I pretty sure everyone reading this agrees that CyanogenMod is the best after-market AOSP-based community initiative ROM available... it's got dozens of new features, fixes, modifications and enhancements over pure AOSP Android... And thanks to the efforts of the entire CyanogenMod team, especially bekit, pershoot & mad-murdock, we have CyanogenMod for our GTablets...
I keep experimenting with the latest CyanogenMod build and the tonnes of other contributions by various people in the community (XDA, TabletRoms, SlateDroid, etc.)... trying to mix and match and find a combination which will give me the best of both worlds...
I started this off as a personal initiative... and decided to share it with the community... but this effort of merging various community contributions into CyanogenMod ROMs takes time and quite often needs thorough testing, it is not practical for me to release updates very frequently. But every so often, when I see commits in CyanogenMod or contributions in the community which would be nice to repack and share with the community, I will hope on board and create a new release.
Please read through the post thoroughy, especially the instructions, troubleshooting and known issues section and familarise yourself with NVFlash recovery.
Credit for most of the amazing features of this ROM goes to the CyanogenMod team (especially pershoot, bekit, mad-murdock) and contributors... and the various other members of the community who share their brilliant mods and tweaks...
Big thanks to dev-host.org team for hosting the files with no bandwidth restrictions...

1. Download the ROM from the appropriate bootloader.
2. Verify the MD5Sum of the downloaded ROM.
3. Clear cache & dalvik cache using Clockwork recovery if you were not using a CM7 2.3.7 ROM prior to flashing this
4. Flash using Clockwork recovery.
1. If you are using the 1.2 bootloader version, use the latest 1.2 bootloader from the 1.2-5274 ROM.
2. Wipe data/factory reset is recommended if you were not using a CM7 2.3.7 ROM prior to flashing this.
3. Since most newer ROMs are based on the 1.2 bootloader, it is recommended that you upgrade to the 1.2-5274 ROM so that you have more freedom to switch to other newer ROMs.
1. Extra kernel modules for pershoot's kernel 126.96.36.199 (lib-2632.48_gb.tar.gz) [For advanced users only]
2. Possible SOD (sleep of death) fixes
TIPS & TWEAKS:
1. You can enable and disable the lockscreen from Settings -> CyanogenMod settings -> Tablet tweaks -> Disable lockscreen.
2. You can switch the mount points of the internal & external memory. You can mount the internal memory as /mnt/sdcard or as /mnt/emmc. Go to Settings -> CyanogenMod settings -> Application -> Use internal storage. This is not part of the CyanogenMod-7.1.0-RC1 build.
3. Since hardware decoding of videos is not working, use MX Video Player or Mobo Player which have software rendering for videos. I recommend one of these players since they have ARMv7 (Tegra) optimised software codecs (FFMPEG).
4. If you want to change the LCD density, download & install PropEditor. Click the "Backup" button to create a backup in case you need to revert back. Then click the "Open" button and in the file manager which opens, tap ".." till you reach the system root. Then tap "system" and the tap "build.prop" to open the editor. Look for "ro.sf.lcd.density" and tap it to change the value. Press the "Menu" key and tap "Save". Reboot.
5. Increasing the DalvikVM memory size will improve performance of the bigger high-graphics Tegra games. Go to Settings -> CyanogenMod settings -> Performance -> VM heap size and set it as 64m.
6. To overclock or underclock your device, go to Settings -> CyanogenMod settings -> Performance -> CPU settings and set the Min CPU frequency and Max CPU frequency to a value of your choice. Click Set on boot to make the frequency setting persistent after reboot.
7. If the Clock app opens every time you press the Home button, it's because Android thinks you GTablet is docked (I don't know why yet!). Install Dock No-Op to fix it.
8. If you wish to use Market Enabler, use the one by For2w. It has many more providers to fake and works properly with the Android Marker 3.x.
1. Due to lack of official drivers and/or OpenGL issues, the video camera does not work and stagefright (media framework) FCs.
2. Due to lack of official drivers & codecs, hardware decoding for videos does not work for most video formats other than MP4. Use a video player with software rendering.
3. If audio from the loudspeaker suddenly stops, plug in a headset and then unplug it.
4. Since the video camera does not work, any video apps which use the stock video camera will not work. Users have reported Fring & Oovoo video chat works.
5. GoogleTalk and Skype now support ARMv7 without neon. This version of GoogleTalk is included in this ROM. But due to lack of official drivers and/or OpenGL issues, both GoogleTalk and Skype cannot broadcast video from the GTablet. The reciepent's video is visible on the GTablet.
6. If you have a problem downloading applications from the Android Market and all/most apps show as "not available for device", try wiping Market data and cache and rebooting. If that does not work, edit build.prop and change the resolution 160 DPI and wipe Market data and cache and reboot.
7. Some user may face SODs (Sleep of Death) wherein the device does not wake after sleep until a hard-reboot. Some possible workarounds are
a. Enabling the lockscreen (see Tips & Tweaks)
b. Setting the device to wake using volume keys (CyanogenMod setting -> Input -> Volume rocker wake)
c. Setting the Min CPU frequency to 312 MHz or 456 MHz (see Tips & Tweaks)
d. Visit this thread for more solutions
8. Google Maps 6.x force closes due to openGL issues with Gingerbread on the GTablet. Use Google Maps 5.x.
1. Try a data/factory reset
2. Use ClockworkMod recovery and try a data/factory reset and format the boot and system partitions
3. Use ClockworkMod recovery and partition the internal SD card as 2048MB ext, 0MB swap, remaining FAT32
4. nvFlash to the stock image
While this has been branded a "stable" release, do note that it is not 100% perfect. I will do my best to help you out if you have any problems, but I take no responsibility if you land up with a brick. Much of the actual hard-work behind the functionality of this ROM belongs to the various developers and teams credited in the changelogs above. Throw a nice thanks to them for their hard work.
