[G Tablet Android Development] zyhong:
MOD EDIT: AS WE ARE REORGANIZING THE GTABLET FORUM - ALL ROMS/KERNELS/ETC WILL HAVE THEIR Q&A POSTS MOVED TO THE Q&A SECTION.

THE Q&A LOCATION FOR THIS ROM IS HERE

Thanks.

---------------------------------------

STANDARD DISCLAIMER: USE AT YOUR OWN RISK. By running this firmware mod, you agree that there is the possibility that you may brick your device and neither myself, XDA nor Viewsonic are responsible for supporting you if that occurs. In this case, it is required that you learn and setup nvflash prior to running this mod.

This is a port of AdamComb with pershoot kernel and some tweak for performance and usability. Thanks all the greatest Adam, Vegan, Gtab devs that make this rom possible.

Install instruction:

1. Make sure the version of your bootloader and download the corresponding rom

2. I guess most of you should already be in CWM, but if you are not. update the recovery to CWM first. Stock recovery might work but you need to do some work and CWM is much better anyway.

3. Wipe data / Factory reset. It might work well, but you will most likely have problems without doing this.

4. Using the "install from sdcard" to install and enjoy.

Features: Very fast and stable

For AdamComb features, check its original post at tabletroms.

1. Overclocked by default, max frequesy adjusted by battery level.

-- you could use setcpu to adjust the min, max frequency. The build-in script for cpu management respect the setting from setcpu

2. Tweaked internal storage & SD card read speeds

3. Annoying ads in programs are blocked

4. Calkulin's battery saving script

5. data2loop works super well

6. pre-load some useful modules at boot time, e.g. cifs, ntfs, utf8, tun.

Known Issues:

1. Anything related to hardware acceleration

2. Stock Camera App does not work.

Beta 3.3: AdamComb v0.2 + pershoot's kernel 07/25/11

[BL1.1]

http://dev-host.org/bsnx1bmz8pgy/GtabComb_b3.3_bl1.1.zip

[BL1.2]

http://dev-host.org/k0zcozlozwgi/GtabComb_b3.3_bl1.2.zip

changelog:

1. update to pershoot 26.32.43 kernel. As already confirmed by some users, this version runs faster and hopefully it also resolve the BT tether issue

2. fix the "import" bug in init.rc.

3. change the label of sdcard and mircosd to be the same as in stock version. So far I have not got any issue and it does fix the "install unsuccessful" problem for some app.

4. remove some libs that does not use in gtab to free up some space. now all the libs in pershoot kernel are available in this rom. just edit the /system/etc/init.d/05modules to add your desired lib in the modules string.

5. Thanks all you guys for testing this and digging into issues. This help me a lot to resolve some issues here. It is the effort from all of us that make this rom better and better.

Beta 3.2: AdamComb v0.2 + pershoot's kernel 07/02/11

[BL1.1]

link: http://www.mediafire.com/?sy8oxpcrdufr4e3

[BL1.2]

link: http://www.mediafire.com/?xqoo08e1m49no1d

changelog:

1. battery life improved a lot

2. overall system performance improvement.

3. partially fixed bluetooth. Not sure how much it works (pulling some of bluetooth libs from flashback)

4. remove street and office app. put back camera app (it still fc, put it here so that some power user could play on it to see if we could find a fix here)

5. fix an issue that usb connect and debug notification does not disappear when the usb is disconnected (well, it still do not work if the usb is disconnected when the system is on sleep)

6. code reorganization and clean up. make it easier for some power user to change settings and plug in scripts without the need to unpack/repack boot.img. Hopefully we could have more power user to play with the system and further improved this rom.

7. change the cpu governor to respect on cpumaster, so you can use both setcpu or cpumaster to adjust the voltage if you really do not like the cpu managed by the buildin script.

8 change bootanimation (pulling from the bootanimation collection by thinkdevoid @tabletroms)

Again, back up and wipe data and factory reset (at least wipe dalvik cache) if you want a smooth experience. Almost all unexpected FCs are related to NOT wiping data
