You can also use this method. It doesn't involve NvFlash, just replace the image inside the .zip with your own and install it with CWM.

Yeah I have used that method before but I would rather have the splash screen changed before I need to go into CWM. Those damn 3 birds are an ugly site and brightens the screen. I have a few custom splash screens where the backdrop is black so its not so bright. I give them a try later.

After the NVflash process shows up and completes you have to press the power button in order to get the tablet out of apx mode for some reason. The NVflash file in the OP for some reason doesn't auto reboot after finished. Then you power the tablet back up and you should boot into TNT. I have flashed that file probably 10 times, reverted back to different roms, and every time I flash it I had to force the power down after NVflash was complete.

Will you be able to send the ICS Rom to my email ?

The gmail limit on attachments is 10mb and the rom is over 100mb so that is really not an option. Are you having trouble downloading it from our site? I just checked the DL and it is working fine here.
i can download. just that the sum check is not right . that is why i cannot get out of apx mode.

thanks

Thanks for this wonderful ROM.

But can anybody tell me how to prevent crashes while using MC video player with equalizer audio effects while playing 720p videos? This is very frustrating. Kindly help me out in this regard.

Will surely be donating via Paypal.

Thanks

I'm loving this ROM.
Its stable except for a few glitches>
I appreciate your hard work.
A request if possible for you.
I use a Zpad T2 and it works perfectly with it.
But my tab is with 1GB RAM but in your ROM ony 512MB shows.
Can you enable 1GB ROM support for my tab.
Or can you tell me how to do it myself.
I would appreciate your help.

Well there is your issue. You are trying to use apx mode to load the rom and not the CWM recovery. The NVflash using apx mode is just to load CWM 5504 along with the stock TNT rom. Thats the only need to ever boot into apx mode is for that reason. Installing the ICS rom would need to be done in CWM 5504. To get there you will need to power down the tablet. Then power back up the tablet while holding down the volume + button. Then you should see in the left top corner on the 3 bird splash screen it loading into recovery. In there you will have options to wipe data factory reset, install from sdcard and what not. Follow the OP instructions and you should be just fine.

Try changing the DPI setting under Settings - Rom Control - Build Properties. I messed around with it over the weekend and set it to 160 and saw less issues. You will need to press the reboot system that populates above after changing it to take in effect.

Ok after allot of compiling my thoughts of what to say all I can come up with is "Your right man". I couldn't go without saying this and I do appoligize for my last post towards you.
I wasn't looking for an apology, actually. What I was expecting is, as I said before, signs of understanding. If you've understood the point I was trying to make, then that's all that's needed... which brings us to this:

So, let me get to this question. If some people are still on stock everything and see this tread and say "Ohh let me try that". Will they be able just to flash the NVflash file in the OP and do everything they need to do with CWM 5504 or will they need to first flash the 1.2 w/CWM 3028 to perform the 2048/0 partition to clean the entire nand then flash the 5504 files on the OP?:rolleyes:
It looks like you're not entirely clear on the 2 storage devices we have on the gTab, and, which programs work on each. Read these 2 posts:

SD card on gTablet

Android partitions on gTablet

Basically: Only nvflash is used to "partition" the 512 MB NAND flash device, and only CWM is used to partition the SD cards (both internal and external). You can't use nvflash on the SD cards and you can't use CWM to partition the NAND device.

To address your question specifically: You don't need to install CWM-3.0.2.8 and then 5504. Just use version 5.5.0.4Beta15.

I have not played w/ the sound crashes that some people experienced. I know there was a kernel side patch that I did add to the kernel that may help fix a few sound crashes. Try it and let me know.



Well I went ahead and started messing around with one setting at a time and you will not like my findings. Just to make sure that the findings were correct I went ahead and started from scratch with the latest firmware and the latest gapps. After letting it sit and rest in I went and changed the LCD density setting to 160 and rebooted. Since fully charged to resting in standby every once in a while I still have sound. As a matter of fact my keyboard is still clicking away while I am typing this. Battery level is currently at 47 percent and still going strong. Also no need to use the soft buttons since the Capacitive buttons have going strong as well.


The bad thing is that the app drawer is a pain in the ass when you have a crap load of apps to navigate through.:D

Well if this thing didn't throw me a curve ball. Been using this all day with a 160 dpi and of course whenI got home no sound. :( ........ I guess I'll be back trying different setting.

Now I'm not fully sure why, but during development there have been a few times where my tablet gets extremely messed up. I have no knowledge why (in the technical aspect), but in logcat all of a sudden I will have out of memory errors and the whole tablet will break and even a factory reset will not fix it. Next I will format the sdcard (2048/0) and then NVFLASH stock 1.2. During that bootup, it will bootloop at the TnT screen. I then have to flash all the way back to stock 1.1, let that settle then move on to 1.2 and then back to DRH. I have no idea why this happens, but it has always seemed to fix any issues.
Is what you're talking about related to the yaffs2 bad block error messages in this post of yours that you asked me to look into?

I guess what I'm trying to say is that I really do believe that booting into TnT does help "something" in the tablet fully stabilize.
...
Basically I'm going to leave post #4 for anyone that is really truly struggling to get this rom to install although it seems like a lot unnecessary flashing.
I have an idea relating to the above, but, its rather theoretical at the moment--meaning it can certainly occur in theory, but, I've not seen it "in the flesh" so far. I'll have to do a few tests to confirm my ideas first.

Get me a logcat and dmesg output using adb the next time this happens--both in your ROM and in TnT after you boot into it following the first nvflash as you say. For TnT you'll have to flash the zip file in the attachment immediately after doing the nvflash to enable ADB (and root) to grab all the logs.

EDIT: I looked at the updater-script for the TeamDRH-ICS-Beta-1.1 ROM as part of troubleshooting another problem I was having a few days ago, and I noticed that you were formatting the cache partition as part of the install. This isn't a good idea: Since /cache is always kept mounted by CWM recovery, formatting it while it is mounted will trash the filesystem for sure. If you want to wipe things clean, let the user do it via CWM--the install procedure already does this. The same logic applies to the other cleanups the script is doing.

Unlike some other ROMs (notably the HC ones and the latest Stock 5699), TeamDRH-ICS does seem to use the /cache partition actively, and using a corrupted filesystem might be one of the reasons for the problems that some people seem to be having. It's worth looking into.

No, what I was talking about I believe was unrelated to the yaffs2 issue. What I was talking about only happens like once every 2 months because I flash so many roms.

I will grab you a logcat next time.

Since /cache is always kept mounted by CWM recovery, formatting it while it is mounted will trash the filesystem for sure. If you want to wipe things clean, let the user do it via CWM--the install procedure already does this. The same logic applies to the other cleanups the script is doing.
I looked into this. Even during the CWM /cache wipe, cache is not unmounted during the format. I do not believe that the unmount is necessary. One thing I was thinking possibly happened was that the format command unmounted the drive automatically, but I am unsure here.

I can get into apx to nvflash. Its suppose to flash tnt 1.2 and cwm. However , after I run nvflash, I am not able to reboot. I am thinking its the bad check sum. Meaning I was not able to download the file properly. (The stock 1.2 with cwm )

recovery boot loops

I did the nvflash, let tnt load, it told me there was an update, so just for the hell of it, I let it load the update. When my tab rebooted, the new update was not applied, and I cant find it to apply manually.

Now rebooting always takes me back to recovery. I cant load the system.

I know I can re-NVFlash it, but in the interest of understanding whats going on, how can I tell my tablet *not* to boot into recovery? Where is that set and how do I change it?

    Now for the moment you all have been waiting for...

    Team DRH (Dirty Reset Hole) is proud to announce the public beta for Ice Cream Sandwich. The name "DRH" came from the hole that all of the developers had to drill into the back of their tablet to access the on-board reset button. As you all probably know, development for this project started back in August and has finally developed into a mostly stable release. Ice Cream Sandwich is a huge jump for the G-Tablet community because along with the building of ICS specifically for SMBA1002 (G-Tablet), the Linux kernel backbone had to be reworked from the ground up.

    DISCLAIMER
    Attention commuters of the intertubes! The group of individuals known as Team DRH take absolutely NO RESPONSIBILITY for any DAMAGE that YOU cause to YOUR device! This "labor of love" we call and Android ROM comes AS IS and is not an official release by any means. If you have not already SOILED your device by flashing a custom ROM then to do so will VOID any WARRANTY you may have left. Team DRH and its affiliates are not responsible if your G-Tablet does any of the following: Explodes, Flies off to space to battle the Flying Spaghetti Monster, Is generally awesome, solves world hunger or explodes... again. (OK We take responsibility for you Tablet becoming Awesomesauce.) So in essence... Flash this totally rad ROM at your own RISK and prepare to Spontaneously Combust with AWESOMENESS!

    WHAT WORKS
    • WIFI
    • Hardware Acceleration
    • Sleep!
    • WiFi
    • Bluetooth
    • Sensors
    • Sound
    • USB/MTP (If you plug in USB while your tablet is asleep you will have a SOD)
    • Capacitive Buttons
    • Hardware Buttons
    • USB Flash Drives
    • Proper SD Card Mounts
    • HD Videos
    • More to come...

    WHAT'S NOT WORKING
    • Camera
    • Microphone (Works but drops after 6-8secs)
    • Possible ROM Slowdowns
    • HDMI Audio
    • More to come...

    • NVFLASH the file following the instructions that are included for Windows/Linux users
    • Upon reboot of tablet let T&T fully boot and then shut it down
    • Reboot into recovery
    • Flash the Rom/Gapps
    • Enjoy

    HOW TO INSTALL VIA DRH NEWS APP
    1. Open DRH News App (You Will be notified that you have an update)
    2. Download Update
    3: Reboot into CWM
    4: Wipe Data and Cache
    5: Flash Update.zip
    6: Flash Your Gapps
    7: Reboot
    8: Enjoy

    FINAL THOUGHTS
    This build has been tested but not to the extreme. It is called a "beta" test for a reason. Sleep is properly working and I have not had to use my reset button in weeks. I'm not trying to scare anyone but the possibility of a kernel panic is still there. This build is very stable and deserves the beta tag but if you find yourself in a snag you might have to press the internal reset button. Here is a picture of where to find the button if you are really in a bind. PICTURE If you have the balls to open your tablet, just drill the reset hole while you're in there. You already voided your warranty ;)

    DOWNLOAD LINK
    ROM/GAPPZ Package: TeamDRH ROM
    ROM (Includes GPS Mod): TeamDRH GPS ROM <-- Only use if you physically installed the internal GPS mod as documented here. This rom is not updated to 1.3 yet.
    Remember this is a beta build. It will run nicely for the most part but I'm sure that there will be glitches a quarks that we have not seen. I will keep the what works/doesn't work section updated so we don't have tons of posts cluttering the thread. Also these links will be updated pretty regularly when we have new builds to release.

    CHANGE-LOG

    The ROM's system folder was very close to the max size our system partition could handle on the G-Tablet and with any bad blocks, it was more than the G-Tablet could handle and installing GApps made it even worse. So on initial boot everything was fine, because all the apps that make temporary files don't make them until after initial boot, but in the process of making those temp files it corrupts system files that are already loaded and running, so on a reboot the system fails because the files are now corrupted. This also effected the overall speed of the ROM. This should be fixed with the increased system partition from 200M to 250M.

    TeamDRH-ICS-Beta-1.3.zip 07/02/12

    HOW TO INSTALL MTP DRIVERS
    Open Device Manager and find the offending TeamDRH MTP device.
    Right-Click and choose Update Driver Software
    Then choose Browse My Computer for Driver Software
    Then click Let Me Pick From a List of Device Drivers on My Computer
    Then choose All Devices
    When that list populates choose Standard MTP Device followed by MTP USB Device
    Click Yes to the warning and VIOLA!

    Hope you all enjoy the TeamDRH gTablet ICS preview!!

    POSSIBLE MARKET ERROR
    Upon start up Android Market may give you an error when you try to download an app. The fix for this is to go into settings/applications and force close market. Upon doing that clear app data and you should be good to go.

    regarding what you say below...
    That's unrelated to whatever slowdowns you're experiencing. But, to clean up /cache, just boot into CWM and "format /cache".

    it seems very slow now running 1.3, prior to this I was running CM7 and the tablet was much faster.
    Yeah. The performance is pretty bad and I'm not sure exactly where the problem lies. Most people point to the paucity of memory being the culprit, and while it may contribute quite a bit, I don't think that's all there is to it: For one thing, there are phones with just 512 MB of RAM comfortably running ICS on them. For another, I see a lot of ANRs and processes being sent SIGQUITs (SIG 3 in the logs) to generate those ANRs. For yet another, the CPU load looks very high when there's lag.

    I also see that the ro.build.type is set to "userdebug" in /system/build.prop instead of the commonly seen build.type of "user". Changing the build.type to "user" stops most of the ANRs. I don't know how Android is built, but, in the Linux world, we usually have 2 kinds of builds for a product: release (what gets shipped) and internal (AKA engineering). The difference is mainly in what compiler flags are used when building the product. For engineering builds, compiler optimizations are turned off and the debugging flags are turned on. These builds are pretty slow and use a lot more memory and CPU than the release builds. Going by what I said about the build.type and ANRs above, this is one thing for the devs to check.

    Try these things to reduce lag:

    In Settings > ROM Control (set on boot if you're happy with)
    1. Reduce dalvik VM heap size for apps to 64M.
    2. Reduce the free memory setting to 50MB.

    In Settings > Developer options (need to set on each boot)
    3. Reduce the no. of Background Processes to 1 or 2.
    4. Check the Destroy Activities ... option.

    Those last 2 really make a noticeable difference, but, you can, if you wish, skip 1) and 4) and still not impact performance all that much.

    the other issue I have on my Gtab... not sure if this is related to the ROM or not.. is that my battery indicator ALWAYS shows 100%. I tried wiping battery stats multiple times in Clockwork but not luck. I also let the tablet's battery drain down to power off. Then plugged it in, booted into clockwork and did another battery stats wipe. Still not luck.
    It's the battery. Don't know what triggers it, though, or how to fix it. I'm trying to look into it.

    One final thing before I hit the sack:
    Most things that people do to detect bad blocks on the NAND (only looking at the dmesg output, for instance) is not very effective. Here's a simple way to be absolutely certain that the ROM has been installed correctly and fully onto the gTab. The idea is an old one, going back to Dan Farmer and his COPS package (early 1990s). Basically, it is to:

    1. have the ROM packager calculate on his dev box the SHA1 checksum of every file that will be installed.
    2. Install this SHA1 checksum file along with the ROM--as, let's say, /system/etc/ROM-files.sha1. (Remove entries for files not installed during installation--not very hard)
    3. User can check using a shell script (or the command below) that the ROM is OK any time he/she wants. If the checksums compute OK, then you too, like me, can sleep blissfully, untroubled by thoughts of any bad blocks doing naughty things to your nice ROM.

    Sample creation of ROM-files.sha1 on packager's dev box. Assuming that all files that go into the ROM are in the system/ and data/ directories in their correct locations:
    Code:
    $ [B]sha1sum `find system data -type f` | tee ROM-files.sha1[/B]
    To check ROM state (on gTab):
    Code:
    gTablet$ [B]su[/B]
    gTablet# [B]cd /[/B]
    gTablet# [B]sha1sum -c system/etc/ROM-files.sha1 2>&1 | fgrep -v OK[/B]
    gTablet#                            [I]No news is good news[/I]

    I think the main reason to format 4g first then 2g is to make sure the sd card part is cleared out byond the 2g region.
    Nope. No such "clearing out" happens with that kind of double/triple/... partitioning. It's simply a waste of time and a distraction from real troubleshooting. An explanation of what happens when you repartition an SD card might help:

    A repartition step on an SD card using CWM on the gTablet involves 2 operations.

    1. The actual partitioning.
    Here, only the MBR--the first sector--on the SD card is written because all SD cards (and also things like USB sticks) are NAND- or NOR-based flash (MTD) devices, but they all look like regular HDDs which means that they all have interface-matching, sector-translation and wear-levelling circuitry (and, on the expensive ones, firmware) built into them. This is also why you can put the standard HDD filesystems like extn, FAT32, etc on them. Raw (untranslated) MTD devices need specialized filesystems like yaffs2 and jffs2 which are coded specifically for them (and, incidentally, you can't put these filesystems on SD card partitions).

    2. The filesystem creation.
    During a filesystem creation operation, only a few scattered bits of data are actually written to the device. If we run through the creation of an ext3 filesystem on an SD card (relevant bits in bold):
    Code:
    ~ # [B]fdisk -l /dev/block/mmcblk2[/B]
    
    Disk /dev/block/mmcblk2: 15.9 GB, 15931539456 bytes
    255 heads, 63 sectors/track, 1936 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    
                  Device Boot      Start         End      Blocks  Id System
    /dev/block/mmcblk2p1               1        1581    12699351   c Win95 FAT32 (LBA)

    ~ #
    you'll see that the size of the partition is 594405 1K blocks, but, only 9365 1K blocks (594405 - 585040), ~ 9.4 MB, scattered all over the place, are written to initialize the filesystem--which involves, mainly, writing a new bootblock, new superblocks and group descriptor blocks, and bitmap and inode-related blocks; plus odds and ends like the bits needed to create the /lost+found directory and the journal (16MB in our example run above, and even here the journal is not "written" fully--only the space needed for it is marked as "allocated").

    The creation of a VFAT filesystem is roughly similar. So, in both cases, not a lot of actual data is written, and in each case the writes are generally scattered all over the device.

    Thus far, this discussion has been at the level of logical filesystem blocks. When it comes to which physical blocks on the SD card are actually written during filesystem creation, things look even worse for people who think some sort of clearing out happens because of the intervening wear-leveling circuitry: Only the HW knows which MTD blocks correspond to which logical filesystem blocks, and the physical MTD blocks standing in for the logical filesystem blocks keep getting rotated as needed by the SD card itself.

    What I think people imagine happens during a repartition is something like this:
    Code:
    ~ # [B]time dd if=/dev/zero of=/dev/block/mmcblk3[/B]
    That command writes zeros to every sector of the internal SD card. Run the command while in CWM (repartition afterwards, please) and see how long it takes to complete. If a repartition step really cleaned out the internal SD card as people imagine, then you would have to wait 45 mins or so for that operation to complete instead of the minute or so that you have to now.

    This is to ensure no data is left over from the previous ROM.
    See the description above. I can guarantee you that unless there are ghastly bugs in CWM, the parted/e2fsprogs code or in the HW, a single repartition operation will get rid of all (user-visible) data on the SD cards.

    Sadly I tried everything I could think of, still no luck. Hopefully now that someone has sent their "stuck at the birds" device in for analysis there will be a fix. I have the CWM install log if that would be helpful. [Update: log attached]
    Looking at the logs, I see that the ROM installation script is still cheerfully corrupting the /cache filesystem for no good reason. It also seems to be trying to remove the dalvik-cache from non-existent devices. Somebody should really scrutinize that install script.

    I was just wondering if you were sure you had the 250mb partition would it be necessary to nvflash.
    Nope.

    If you could just do a wipe/factory reset, wipe cache, wipe davilk cache and the flash the 1.3 rom.
    Only a "wipe data/factory reset" is needed. You'll see that it does the other 2 (wiping cache and dalvik-cache) if you look at the messages the operation prints.

    CWM 5504 B15+Touch and ICS

    Process I followed to actually get the latest ClockWorkMod w/touch working AND be able to install ICS (I had a TON of issues with boot-into-recovery-only, not booting at all and only showing the birds, booting into stock rom but not being able to get into recovery anymore... this is how I got it working.)

    Following this exact process I get success everytime now.

    1) Turn your tablet OFF and REMOVE THE microSD CARD!! I repeat, remove the microSD card!!

    2) Download THIS "nvflash_gtablet_2010110500.zip" from HERE (delete the other zip if you downloaded elsewhere):
    http://dl.dropbox.com/u/66090731/nvflash_gtablet_2010110500.zip

    3) Download THIS "nvflash1.2_5504b15.zip" from HERE:
    http://dl.dropbox.com/u/66090731/nvflash1.2_5504b15.zip

    4) Unzip "nvflash_gtablet_2010110500.zip" to "nvflash_gtablet_2010110500"
    5) Unzip "nvflash1.2_5504b15.zip" to "nvflash1.2_5504b15"

    6) Press and hold Volume - (VOL. DOWN) and the power button at the same time, release the power button once the screen turns on, keep holding VOL - until screen turns off; you're now in whats called APX mode.
    7) Plug your USB cord into your computer, and into your G-Tablet

    If you have NEVER installed the USB drivers before, do step 8, otherwise skip to step 9:
    8) Go to Start/Control Panel/Device Manager and hit the Update Driver button for APX. In the popup, choose to specify manually and browse to the "nvflash_gtablet_2010110500" directory and choose the "USB" directory. Let the drivers install and proceed to step 9.

    9) Go inside the "nvflash_gtablet_2010110500" directory
    10) Double click nvflash_gtablet.bat , a CMD prompt window will open and start doing stuff - let it run until it says press any key to exit - that means its done.
    11) Let your G-Tablet do a full boot up into the TnT ROM, then shutdown (Power Off)

    12) Put your G-Tablet back into APX Mode. (Press and hold VOL. DOWN and the power button at the same time, release the power button once the screen turns on, keep holding VOL - until screen turns off).

    13) Go inside the "nvflash1.2_5504b15" directory
    14) Double click nvflash_gtablet.bat , a CMD prompt window will open and start doing stuff - again let it run until it says press any key to exit - that means its done.
    15) Let your G-Tablet do a full boot up into the TnT ROM, then shutdown (Power Off)

    16) Put your G-Tablet into Recovery Mode. To do this, press and hold VOLUME + (VOL UP) and the power button at the same time, release the power button once the screen turns on, keep holding VOL + for a few seconds; now you should be in the ClockWorkMod recovery with touch capability. At the top it should say 5.5.0.4 Beta 15.

    Now its time to follow the "How to install" steps from the first post. DO ALL OF THESE!
    1)
    a. Wipe Data/Factory Reset
    b. Wipe Cache
    c. Wipe Dalvik Cache
    2)
    a. Format boot
    b. Mount then Format data
    c. Mount then format system
    d. Format cache
    3) Re-partition internal sd with 2048/0
    4) Mount USB and copy your ICS ROM and Gapps zip files over
    5) Flash the ICS ROM (this may take a while to complete, do not mess with it until it's DONE)
    6) Flash Gapps (this may take a while to complete, do not mess with it until it's DONE)
    7) SHUT DOWN / POWER OFF
    8) Insert your microSD card back into your G-Tablet
    9) Start up normal and let it boot into the ICS ROM.
    10) Complete first setup and then let sit and sync for half an hour to an hour.
