LAST UPDATE: 6/21/2011 (alpha 6.0)







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, Slatedroid 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.





Their forum is here: A BIG THANK YOU TO MRGUY, DJ_STEVE, Clemsyn, Pershoot and all the Adam and VEGA developers, for this excellent port!!!!! Most of this port comes from what they've created. I'm just tweaking it a little for GTAB users and packaging it. The alpha 6 is a mashup of both HC16 and the VEGAComb 1.5.1 beta (I'm still calling it an alpha, given the OpenGL issue).Their forum is here: http://tabletroms.co...m-%28Updated%29

==================================This will flash your boot.img, recovery, bootloader and system, so be aware of this. You are also REQUIRED to wipe your user data after you flash to this ROM, so please BACKUP ALL DATA before attempting this.The 1.2 GTAB dev branch and the Adam dev branch seem to be the same exact branch, and the kernels are (mostly) compatible. And we are currently using Clem's HC-compatible kernel, which is 1.2 branch based.The space has been reduced to the point that a vanilla GTAB can now be flashed to run this.This is your backout in case something bad happens, so I would recommend you understand how to use this, in advance. Link details: http://forum.xda-dev...d.php?t=861950. nvflash is specific to Tegra 2 devices only. For users on 1.1-based ROMs (ie. stock, VEGAn, gADAM TNT Lite 4 etc.), learning nvflash is HIGHLY recommended as the risk of a soft-brick is higher.For example, build 4349 is the latest 1.2-based stock ROM, as of this writing. Details on how to return to a stock 1.2-based ROM are here: http://www.slatedroi...sions-g-tablet/ Other 1.2-based ROMs should also work safely (ie. Century Eyes, Mountain Laurel, Brilliant Corners). A 1.1-based source is more risky (see below) but is possible and I have tested 3588 stock to BOS directly, with no issues.(ie. TNT Lite 5 / TwoTapsX / 4349 stock / Century Eyes / Mountain Laurel)- Extract the RAR to the root of your internal memory. So, you'd have a recovery folder and an update.zip on the root of the mounted drive.- Reboot into recovery. The update should occur automatically (click on the Home button to see the build details while it's running) . Once completed, it should reboot automatically.- The device should take some time to initialize (two to three minutes, so be patient), then will boot into the GUI. If it gets stuck (and it likely will if you came from a different ROM), reboot into recovery one more time and wipe data / factory reset and reboot. I would NOT recommend setting up any Wifi at the initial setup screen, wait until the after the setup before doing that (some users, myself included, have had issues doing this at the initial setup screen so I would skip it).Since there's no mount to PC option yet, you can upgrade to each new version via clockworkmod. As of alpha 2.2, cwm is flashed with the HC ROM. So this is my recommendation on how to upgrade:- Download new version of HC, and extract the update.zip from the RAR file.- Run cwm (as of alpha 2.2, I added it to the ROM). Go to Mounts and Storage, then mount USB. The internal memory should now mount to your PC.- Add the new update.zip somewhere to your internal memory. What I usually do is create a "backups" folder, drop the version in there and rename it to something more readable like "BOS_Alpha2.2.zip".- Unmount the device PC from your PC, then unmount from cwm. Then run the update.zip as you normally would and choose that file you just added.Btw, as long as you stay on the 1.2 dev branch, you can add 4349 stock or any other 1.2 based ROM in there and use cwm to install, without risk of brickage.(ie. TNT Lite 4, VEGAN-Tab, G-Harmony, Calkulin's ROM etc.)- Ensure that your device is running build 3588 standard recovery. This is a requirement to minimize the risk of a soft-brick - I cannot stress this enough! gADAM 1.3.0+ and TNT Lite 4.3.0+ have a Recovery Pack built-in to allow you to easily add standard recovery, if you are using clockworkmod. Do NOT use clockworkmod to flash up to a 1.2-based ROM or you WILL soft-brick your device. For other 1.1-based mods, you can install the 3588 Recovery Pack or flash 3588 standard recovery via an update.zip file. Or, flash to 3588 stock (with stock recovery) for the safest baseline.I want to stress this, as this is important - BE VERY CAREFUL on a 1.1 source. If you flash with clockworkmod from a 1.1 ROM to a 1.2 ROM likeof, YOU WILL SOFT-BRICK your tablet 100% of the time. If you are not sure if your device has 3588 stock recovery, don't take the risk -- flash to 3588 stock before you attempt this HC mod!Other than these caveats, the installation is the same as 1.2 users, above.This is a 1.2-based mod and I would recommend that you backout to the latest stock ROM (4349, as of this writing). Please see this post on instructions on how to flash to a stock 1.2-based ROM: http://www.slatedroi...sions-g-tablet/ If you want to backout to a 1.1-based ROM or mod, you MUST have a standard 1.2-based recovery (like 3991 or 4349). Since this ROM installs a 1.2-friendly clockworkmod, then you need to remove it - see the "Recovery Pack" section on how to backout to standard recovery. Again, running stock 4349 is your best best to get to a "gateway" 1.2 ROM before you jump back to a 1.1 ROM/mod.Once a standard 1.2-based recovery is confirmed installed, you can use any of the following ROM's to backout to a "legacy" 1.1-based firmware: 3588 stock, TNT Lite 4.3.0+ or gADAM 1.3.0+. You would just use the standard instructions for these (ie. add the update.zip and recovery folders to the root of your drive, and reboot into recovery). Other 1.1-based ROM's may not work (ie. VEGAn or any of the GB ROMs), so PLEASE tread carefully here!I have tested all of these scenarios and the backout does work, most of the time. However, as always, there is a risk here so I would HIGHLY recommend that you setup and master nvflash BEFORE you attempt backing out. That's just in case the backout fails and you need an emergency procedure to unbrick your device.NOTE FOR TNT LITE 4.3.0+ / gADAM 1.3.0+ -- recovery will be broken, after the downgrade. In this case, just run their Recovery Pack and you can fix it (see the TNT Lite first post on XDA, for details).Also see gojimi's post on backing out from a 1.2-based ROM to a 1.1-based ROM: http://forum.xda-dev...d.php?t=1036956 I have included part of the 4349 recovery pack in the last few alphas in case you need to backout to standard recovery. To do this, either use adb or a Terminal Emulator, then type "su" and then this:(this adds back standard recovery)(this adds back cwm recovery)-------------------------(a6.0) Added Pershoot GB kernel. Seems stable so far, adds USB mounting (thus cwm was removed from the ROM, no longer required)(a5.2) Based of HC16 -- Gmail possibly working better(?), media scanning is working, Gallery is working for me.(a5.1) Still based on a5.0, but fixed the blank browser.(a5.0)Updates to reflect Adam HC15 changes (storage is fixed, but we lost the enhanced shutdown screen)(a4.1) Sound Settings now work (storage does not, however), tweaked the app selection a bit.(a4.0) First attempt to combine aspects of VEGAComb beta 1.5.1 and Adam HC14.(a3.3) Tweaked lowmem settings (thanks!) and added ACER buttons back (thanks!)(a3.2) Sleep improved, constant restarts after a data wipe seems to be corrected, as well.(a3.1) Fixed the messy dalvik heap size.(a3.0) Updated to Adam u14 (this moves from an ACER UI to the ASUS UI).(a2.4) Small additions to /data/app (for standard recovery users only, adds additional apps to user data). Added run-parts for Clem. Updated cwm to rev5.(a2.3) Updated to Adam u13, moved Books, Maps, Street to /data (won't install with cwm, keep in mind). This freed up another 15MB of space on /system. Gmail / Email are now working, thanks to u13 and the VEGA devs! If you are using cwm, you can sideload the data apps later or get them from the Market.(a2.2) Updated to Adam u12, adds the new mod name. Also adding 1.2 bootloader and cwm 3.0.2.8 recovery, for 1.1 jumpers.(a2.1) Gapps! At least the Market, and YouTube (again, a big thanks tofor making that happen!) updated to be based on the Adam update10 image.(a2.0) Version 11kernel added for HC, gsensor fixed (thanks tofor the tips!), newerboot logo.(a1.2) Sound! (thanks tofor the fix, andandfor testing!), standard video might work (I tested an mp4). Audio includes EQ, which is actually superior to any vendor build I've used.(a1.1) Added root (thanks tofor the Xoom su!), a few additional apps, better boot screen (thanks!)(a1.0) First releaseSee this TR Wiki for an updated list of issues: http://tabletroms.co...Log&redirect=no . Ours will be very similar. But to summarize:- Camera isn't working (pulled out the app for now)- Browser is working, but OpenGL is disabled for it to work. That means no Flash video on the stock browser.- (High-def) video playback does not work, yet.- For the Market, REBOOT after setting up your Google ID for the first time. This seems to be needed for alpha 6, at least.- I would recommend turning off Compatibility Mode (which is why I added the Spare Parts apk). It will correct screen issues for some apps, and over in XDA it's been said that it might improve Market downloads as well.- For overclocking, you can use "CPU Master", in the Market (thanks nitefallz!) Note that CPU Master free does not install to load on boot like the paid version. You have to set the CPU speed manually each time you start up.- There's an adhoc patch that can be attempted, see this post for details: http://www.slatedroi...post__p__202078 (thanks,==================================alpha2.2 -- this is a screenshot from my GTAB:Adam demo (our device has similar speed and functionality):==========================================ARCHIVESmd5sum: 3de73c9727e1461c947a15c1d503fb30(updated 5/19/2011)md5sum: b120b5dde298a743a9163cab68b434c0(updated 5/15/2011)md5sum: afa130f94a3fce1bb15b51c033853ef1(updated 5/10/2011)
