So I keep having these epic battles with my tab where it will randomly turn the screen on after I lock it. It happens all the time and I usually just turn the screen off with the power button. Sometimes will turn right back on as if trying t mock me, so I just let it turn itself off. Well after it turns off, it turns right back on. It does this from time to time and multiple times a day. It just starts to get annoying after watching it turn on and off for a few minutes.. any ideas on what to do?
From the OP:
ROM does have issue where at times, will not go to sleep (screen will turn off then flash back on) aka "blinkies"
We're working on getting it fixed.
Stuck on 3 birds after flash
I flashed this version several times on several different GTabs (including one that was brand new) and all but one did the same thing. The first time I experienced it, I did a full NVFlash and repeated the entire prep and flash - with the exact same results again.
After that, I just went back into CWM, did a factory reset and flashed the ROM again and it worked. Now, each time that I have the issue, I follow the same procedure and it works on the second flash.
I have not spent enough time to try to isolate whether it is the specific responses that I provide to the install script, but I doubt whether it matters. As you said, it does it whether you select GAppz or not.
The only thing that MIGHT be a problem is the selection to auto-reboot after flash. Although choosing that option does not allow you to do the clear cache / dalvik (normally important), the script appears to do it for you so I don't think it matters.
For a step-by-step guide (including what to do when you get the "3 birds" loop), visit my site at: http://raywaldo.com/2012/02/ice-cream-sandwich-on-g-tab/

help the cousin - malata zpad t8
Unfortunately whyberg said that the kernel is working but there are many problems, and he's pessimistic about a stable build.
Can you help him?, or point him to someone, suggest starting a thread for the build...
If devices are needed i think the vendor would give 1/2 or maybe there can be some sort of collaboration with their team (i think they would agree to that, it's a lot of pressure here for the promised! ics build . They have ics for other tablets in their portfolio, but not for T8 although they say that are trying).

My tab has a lot of pre-forcecloses meaning the moment it thinksthe apphas frozen giving you the option to wait or close.
Well its doing that many times. Since build alpha 1
even though the app has not frozen yet or at all.and pressing wait. Gets you backlike noting happened ..
Very annoing
That's what makes me go back to cm7 from time to time
(And asking for GB kernels)
Besides that. The rom is fantastic with every build it gets faster.... I like it so much.....
Thanks for your hard work

I was getting a ton of those as well with 1.2. Then I read that the included DSP Manager was CPU intensive. That's the kind of thing that stalls app loads long enough to spawn close/wait dialogues so I froze that sucker with Titanium Backup. Then, as suggested by one of the denizen's of this or that other forum, I wiped the cache partition and the Dalvik cache for good measure. That seems to have settled the stalling issue and everything(!) runs more smoothly now.
You're welcome.
You're welcome.
First off, that's an awesome site you got there. really a gtab bible!
That's the exact instructions i followed while flashing ICS...i've been following your blog since i got my gtab...i installed flashback immediately after unboxing, following your site only.
However, even re-flashing the ROM a dozen times now hasn't fixed the issue. i faced the same issue with the previous version of ICS too. have even trying the long NVFlash method.
Another thing that i'm curious about: you're supposed to do cache and dalvik wipe, however every time and with every rom (HC or ICS), when i select the dalvik wipe, i get the error "E:\ volume path not found" or something of this order. Is this normal? and if the path wasn't found, then what's the point of doing the dalvik wipe? To clarify, I don't use an external SD card.
dalvic should not live on external sdcard
Thanks for the comment about the site. I am pleased that it has helped you and others.
There are errors about the SD ext that are normal. But if the error is about the dalvic cache being on the EXTERNAL sdcard then you have a problem. Did you follow the NEW guide that I wrote a few days ago? It sounds like you need to partition the internal SD.

Best Rom
Just want to say this Rom is so buttery smooth, hulu works, hardware acceleration and games are working good. Just Love this Rom. Much Love to those developers. Thank you

So I wanted to ask this somewhere but it slightly related to the ROM.. has anyone else seen the g tab case with built in keyboard on amazon for $23? I just saw it and I thought it was a decent idea since my last case went to crap. I just wonder if there is a better case out there for the money and I also wonder if the USB keyboard will work with ICS. I know people design things for un-rooted devices. Is this a good case to buy or should I look somewhere else. Heck I could just leave it naked. Any ideas will help!
Nice find .... will try that later but I thank you since right now

gTab USB Keyboard on ICS
I did a review of it over a year ago here: http://raywaldo.com/2010/12/review-gtab-case-keyboard/
Since that time, my impressions have gotten even worse. You get what you pay for.
If you want a case, get a cheap slip case (I found one for about $7 that works great).
For the keyboard (and mouse), a better solution is to use standard USB devices. See my review here: http://raywaldo.com/2012/04/usb-keyboard-on-gtab/

Thanks! I really didn't care about the keyboard in the first place. I thought it was a nice feature, hit my main objective was to find a case that my tab fits securely and snug in. The keyboard would have been cool for notes in class and what not. Thanks for the review. Definitely helped me make my decision

Hulu? Really?
Hulu works?? Whether Dolphin HD, Dolphin for Tablet or Opera, I get the "Hulu doesn't support your platform" message (after the video struggles at length to load." I have all agents set to "Desktop" as any mobile platform seems to be a non-starter w/ Hulu.
It's the basic Hulu.com service I'm trying to use, not Hulu Plus.

I have a few things that are a little funny going on. I did a very clean install following directions. This update gave me the binkies-which I know is being worked on. I get a lot of times where it seems to be grinding away and I get the force close or wait message. Also, my battery in the status bar seems to lock at some percentage that I start with when I unplug it. It doesn't show that it's charging either. Sometimes it acts as if there is a bad connection with the charger-odd since it is only with this rom. This is new, it worked fine for a while.

I have been using that particular case since I had my tablet and I am still using it currently. It is a nice case and with the help from mr. Velcro my tablet stays put in it. The usb keyboard works great and I haven't yet found a rom that hasn't worked with it so far. Don't pay attention to it being cheap. The only thing that broke on me is the kick stand, and honestly I really didn't use it much anyways.

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...

HOW TO INSTALL
- Boot into current version of CWM and "Wipe data/factory reset"
- Partition Internal SD Card (2048M/0)
- Turn tablet off
- Download the following file <--- Seriously don't skip this step unless you are 100% positive that you have a 250M system partition
- 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.

That's unrelated to whatever slowdowns you're experiencing. But, to clean up /cache, just boot into CWM and "format /cache".
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.
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:
To check ROM state (on gTab):Code:$ [B]sha1sum `find system data -type f` | tee ROM-files.sha1[/B]
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]5
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):
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").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) /dev/block/mmcblk2p2 1582 1825 1959930 83 Linux /dev/block/mmcblk2p3 1826 1862 297202+ 83 Linux /dev/block/mmcblk2p4 1863 1936 [B]594405[/B] 83 Linux ~ # [B]/root/mke2fs -j -m0 /dev/block/mmcblk2p4[/B] mke2fs 1.42.4 (12-June-2012) Filesystem label= OS type: Linux Block size=[B]4096[/B] (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 37200 inodes, [B]148601[/B] blocks 0 blocks (0.00%) reserved for the super user First data block=0 Maximum filesystem blocks=155189248 5 block groups 32768 blocks per group, 32768 fragments per group 7440 inodes per group Superblock backups stored on blocks: 32768, 98304 Allocating group tables: done Writing inode tables: done Creating journal (4096 blocks): done Writing superblocks and filesystem accounting information: done ~ # [B]mount /dev/block/mmcblk2p4 /root/[/B] ~ # [B]df[/B] Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 224188 32 224156 0% /dev /dev/block/mtdblock4 222208 1296 220912 1% /cache /dev/block/mmcblk2p4 [B]585040[/B] 16860 568180 3% /root ~ #
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:
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.Code:~ # [B]time dd if=/dev/zero of=/dev/block/mmcblk3[/B]
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.

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.

Nope.
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.5CWM 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.
