[G Tablet General] roebeet:
THIS MOD HAS BEEN RETIRED. This is a 1.1-based modded ROM. I am no longer developing 1.1-based solutions but I am leaving this post up for current users, or for anyone who still wishes to use it. ​

==================================

What this is

TNT Lite is an alternate 1.1 based ROM for the GTab, based on the stock ROM that Viewsonic supplies. This will flash system, bootloader and your kernel, so be aware of this. Clockworkmod is NOT recommended for use with TNT Lite flashing (as it does not update the bootloader as required by the vendor), but it is an option if you feel you must use it (ie. if you are stuck in a boot loop and need to wipe your user data). It is a "mostly stock" ROM.

TnT Lite makes the following changes to the stock firmware:

- Rooted and has SuperUser app preinstalled.

- Google Marketplace has been added. It might be crippled by default, but it's fixable with this hack: http://xdaforums.com/showthread.php?t=845175. Also added erraskey's mahimahi modification.

- Removes the TnT homescreen and replaces it with a stock Google launcher

- Removes the over-the-air (OTA) updater

- Removes most of the TnT stock apps and replaces them with standard Android replacements (the only exception being the web browser which cannot be changed yet, and the music application).

- Development and Spare Parts apps have been added.

- Busybox pre-installed. Thanks to bekit for his work on cm6.1!

- Adds VEGA IFile Manager, replacing Estrongs.

- Adds back the /system/xbin folder, which VS removed for some reason. Internal binaries like “sqlite3" now work.

- Adds a full YouTube app.

- Flash is pre-installed.

- Adds extra UI animations (thanks to Rothnic for those enhancements!).

- Includes a TnT Lite version number in the "About Tablet" area.

- Adds an Adam keyboard and Sniffer app (thanks to gojimi for that!). Also adds a Gingerbread-based keyboard.

- G-Sensor hack and Calibration hacks (see the archives for nods on that).

Recommended Pre-requisites

1. Setup and learn how to use nvflash. This is your backout in case something bad happens, so I would highly recommend you understand how to use this, in advance. Link details: http://xdaforums.com/showthread.php?t=861950. nvflash is specific to Tegra 2 devices only.

2. Setup and learn how to use adb. This is a standard Android tool that will give you a remote shell into the device. This is helpful to push and pull files, and do general troubleshooting. For example, you can do a data wipe within adb if your device boot loops by typing "adb remount" and then "Adb shell wipe data" and then reboot. A VERY helpful tool for anyone modding their device.

Information on adb and how to install it / use it can found in several area in XDA, or on other Android sites. It's part of the Google Android SDK.

3. Have your device on a stock ROM baseline, or a previous version of TNT Lite 4.x or below. For example, build 3588 is the lastest 1.1-based stock ROM, as of this writing. Details on how to return to a stock ROM are here: http://xdaforums.com/showthread.php?p=9247367#post9247367. An earlier version of TNT Lite (4.x or earlier) is also an acceptable baseline. TNT Lite 5.x is a higher risk -- please see the TwoTapsX post for details on that.

Other 1.1-based ROMs should also work, but the lowest risk imo is 3588 stock or an older TNT Lite version. This is how I generally test my mods.

Installation for legacy 1.0.1 or 1.1 stock/mod users

a)Instructions for those with standard recovery:

- Extract the RAR to the root of your internal memory. So, for example, if your device is mounted on your Windows F drive, you need to extract the RAR so that you have an F:\update.zip file and an F:\recovery folder. Then, unmount the drive cleanly.

- Power off the device, then begin the flash process by holding the power switch and volume up switch for several seconds. You should see a recovery screen and it will take 1-2 minutes to complete.

- After the update is complete, the system will reboot.

- Optional, but recommended. Do a data wipe / factory reset once the device is rebooted. Settings -- Security -- Factory Data Reset.

Note: these instructions are for the internal memory. If you have no access to that (ie stuck in a boot loop), you can add the files to a microSD card and that will work. However, you need to make one edit to the \recovery\command file, which is a text file. Edit it in notepad and change "SDCARD" to "SDCARD2" and resave it. But, make sure that Windows doesn't add a .TXT extension - it HAS to be called "command".

b)Instructions for those with clockworkmod .8:

- Extract the RAR and place the update.zip file anywhere in /sdcard (do NOT just copy the original RAR, that won't work! You have to open up the RAR and copy the update.zip inside. You don't need the /recovery folder for cwm). I would recommend putting the file on the root of /sdcard, since it will be easier to upgrade that way.

- Reboot into recovery. Do a backup first, as that's always a good idea. :)

- Then, choose "apply sdcard:update.zip", assuming you added the update.zip to the root of /sdcard, and run it.

- Reboot.

- Optional, but recommended. Do a data wipe / factory reset once the device is rebooted. For cwm users, you would do that within the cwm tool itself.

Note #1: The first reboot might sit for a long time (as of 4.4.0, it's a Honeycomb animation) - just wait and it should finish within 3 minutes or so. If if does not or you see the device looping, you might need a user data wipe.

Note #2: "Status 7" errors. I had this happen to me once, and an SD re-partition corrected it. I believe it's some kind of partition corruption that eventually manifests itself.

Backout

- Setup and install the 3588 stock ROM. Stock ROM is here: http://xdaforums.com/showthread.php?t=842000

New for TNT Lite 4.3.0+ : GTAB 3588 Recovery Pack

This is a set of scripts to change between standard recovery and clockworkmod recovery, without having to reboot. All you need is adb or a Terminal Emulator package.

I don't use clockworkmod for flashing ROM's anymore, due to its inability to flash the bootloader (something that may be required, in the future). But I still use it for nandroid backups and data wipes, so this is how I can easily switch between the two.

a) To flash recovery to 3588 stock recovery, using your GTablet

- Download the app "Android Terminal Emulator", by Jack Palevich.

- Run the app, toggle the soft keyboard and change the font settings, if desired (default is very small)

- Type "su" (Superuser should allow su access.

- Type "fixrecovery.sh". This should run the flash_image tool and complete in 5-10 seconds

Reboot into recovery to test. 3588 stock has no options, so assuming you have no update.zip in the root of your /sdcard, it should just error out with an "!" error (that's what we want to see).

b) To flash recovery to legacy clockworkmod .8 bekit version recovery, using your GTablet

- Follow steps 1 to 3, above

- Type "cwmrecovery.sh". This should run the flash_image tool and complete in 5-10 seconds.

Reboot into recovery to test. You should see the clockworkmod .8 bekit screen, which means the flash was successful.

c) To flash either recovery with adb

Just use an "adb shell" and then run the shell script needed.

Issues / Caveats

More than a few users have reported a reboot looping issue either during, or shortly after, upgrading to this firmware. I would go on the assumption that this could happen to you, so I would be prepared for that and try some of the possible fixes that users have reported, below.

Pre-req: Have a microSD card ready of use. This will be the only way to re-flash or install clockworkmod, if you get stuck in a reboot loop. If you don't have a microSD card, then you're only fix would be to use nvflash to fully erase the system (see the steps in the nvflash link in this post). With that in mind, I would try these steps, in this order (you'd try the next step if the first step did not fix the issue)....

- Try to reflash first, using the microSD.

- Try to reflash to TnT stock - again using the microSD.

- Install clockworkmod recovery (see below) using the microSD, which will give you extra capabilities. Then, run clockworkmod recovery and wipe your user data.

- Re-run clockworkmod recovery and re-partition your SD card. Suggested setup (as of Jan 2011) is 2048 and swap of 0. (this last step will wipe the /sdcard data, so keep that in mind).

Lastly, check out this thread for acore FCs: http://xdaforums.com/showthread.php?p=9454175#post9454175 (thanks, digger44!)

- Sleep mode (clicking on the power button) doesn't seem to work. There is no known fix, other than adding a customized kernel. Another suggestion is to leave the device to "never sleep", at least for now. EDIT: Should be fixed with 4.4.0.

- When clicking on the "Notifications" button in Settings (the one that's greyed out) the device semi-locks. To unlock, just click on the "!" button i the uppper right side on the device, on the status bar.

Other Items of Note

- Clockworkmod bekit v.8 only update.zip (for technical users only -- ONLY use with TnT Lite 1.x to 4.x, or other 1.1-based legacy mods) : http://www.mediafire.com/?dvleg4oatkfxm7w

This is a replacement for standard recovery. It adds the ability to backup and restore system images, for example.
