CLICK PIC FOR TEAM HOMEPAGE

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...


List of Common ICS Problems
http://forum.xda-developers.com/show...php?p=23146434

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.

TeamDRH-ICS-Beta-1.3.zip 07/02/12
  • Kernel changes to help stability
  • Wifi Updates (latest bcmdhd android code)
  • Changes to sound (should reduce audio lag)
  • Mic Partially Working (Will record for roughly 6 - 8 seconds)
  • Dock Support with HDMI and Ethernet (No Sound over HDMI yet) This includes a dock clock mode
  • "Blinkies" Have been fixed
  • Updates to CM9 code. Now includes lots of the CM9 features
  • Overall stability improvement
  • New Boot Animation
  • Added Sound to Boot Animation (Optional)
  • New Default Wallpaper (created by annel)
  • Installer Updated
  • Gappz Changes
  • Updated Google Plus
  • Updated Google Books
  • Updated Google Chrome Browser
  • YouTube Updated
  • Google Drive Updated
  • Google Play Updated
  • Google Currents Updated
  • Added Google Magazines (From JellyBean)
  • Added Google Ears (From JellyBean)
  • Probably more changes too this is just all I could remember

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.

IF ALL ELSE FAILS (Only do this If I tell you too)

Wow I bought my Gtab Yesterday and this is the first thing I have tried... it is mind blowing !! If the Out-of-the-box feeling of this tab disgusted me to 50% this has excited me to 200%

Keep up the good work guys !!

Just one thing - the text on my gTab appears kind of blurry is it a resolution thing or is it because of the screen.

Overall superb !! Thanks a million for making my $275 INVESTMENT worth it !!

Some Donation Definitely Headed Your Way.!!

For those of you who are really struggling to install this build here is a (most likely) fail-safe method of getting it to work. It is lengthy and sucks, but is most likely worth it in the long run.
  1. NVFLASH the following http://www.mediafire.com/?brd9u48iefdqcc7 Upon reboot, boot into recovery and partition sd card. 2048M/0M
  2. Turn off tablet
  3. NVFLASH the following (full 1.1 stock) http://www.mediafire.com/?48roksff1xji3y0
  4. Fully boot into TnT (yes, you have to do this!)
  5. Turn tablet off
  6. NVFLASH this (full 1.2 stock) http://www.mediafire.com/?0rgkcd0k4v30z4u
  7. Let TnT fully load yet again
  8. Next NVFLASH TeamDRH recovery found here http://www.slatedroid.com/topic/2875...very-team-drh/
  9. Boot into recovery
  10. Mount usb and delete all folders that were made from TnT. Then copy on ROM and Gapps.
  11. Flash our current build of ICS (found in OP)
  12. Cross fingers and hope it boots

The technical aspect behind this is supposedly TnT tags bad blocks in the nand and moves them. This method got me out of a nasty bootloop spree the other night, so it does work. If this works for you, let me know.

Very unlikely.

The internal SD card is not a "raw" NAND device, so any bad block handling will be done, transparently, by the hardware. I doubt if TnT can get to that layer. In any case, most of those steps only touch the built-in 512MB NAND flash.

Could that re-allocate bad blocks in the NAND?

What kind of bad block? Factory-marked bad blocks on raw NAND devices are not reallocated. The filesystems (YAFFS2, JFFS, UBIFS) for these raw NAND/NOR MTD devices are designed to skip marked bad blocks. CWM and the utilities that come with it (dump_image, erase_image, flash_image) do this too.

BTW, fosser2, can you use the gtablet.cfg in this post instead of roebeet's version for people enlarging their system partition and installing the 1.2 bootloader.

For example these are the bad blocks I'm talking about:

Code:
<6>[    3.334646] yaffs: dev is 32505859 name is "mtdblock3" rw  
<6>[    3.334798] yaffs: passed flags ""  
<7>[    3.334890] yaffs: Attempting MTD mount of 31.3,"mtdblock3"  
<7>[    3.441293] yaffs: block 1393 is bad  
<7>[    7.661086] yaffs: yaffs_read_super: is_checkpointed 0  
<6>[    7.661433] yaffs: dev is 32505860 name is "mtdblock4" rw  
<6>[    7.661520] yaffs: passed flags ""  
<7>[    7.661613] yaffs: Attempting MTD mount of 31.4,"mtdblock4"  
<7>[    7.733488] yaffs: block 1255 is bad  
<7>[    7.733613] yaffs: block 1256 is bad  
<7>[    8.188697] yaffs: yaffs_read_super: is_checkpointed 0
full dmesg here http://pastebin.com/tyPm3DpH

As for expanding the system partition: As far as I know, we aren't doing that. We are using "stock" values.
