TeamDRH (Dirty Reset Hole) presents the first public alpha for Android 4.1.X (Jelly Bean).

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!

HOW TO INSTALL

• Download the following file <--- Seriously don't skip this step unless you are 100% positive that you have a 350M system partition (md5: 256a4bf1da503f4a1ec1f998a00a05f2)
  
• Boot tablet into APX mode by holding volume down and power for about 6 seconds
  
• Plug tablet into computer
  
• NVFLASH the above following the instructions that are included for Windows/Linux users
  
• Turn tablet back on (it will boot into recovery)
  
• Partition Internal SD Card (2048M/0)
  
• Enable USB connection and copy DRH ROM onto internal/external sdcard
  
• Flash ROM that was copied over
  
• Enjoy!

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. In this release the system size has increased from 200MB (stock gtab) to 350MB. Since Jellybean is so large in size this is needed. The cache directory has been syslinked to the internal sdcard as to save space on the NAND. This is the same setup that ICS 1.3.2 had.

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
• Dock
• More to come...

WHAT'S NOT WORKING

• Camera
• Microphone (Works but drops after 6-8secs)
• Possible ROM Slowdowns
• HDMI Audio

Version Info:
This build of JB will be starting at Alpha 5.0. Reason being in the ICS ROM version's 1.x interfered with bootloader version and Android version. We are trying to get away from that mess so we just decided to jump to 5.0. 5.0 is basically the equivalent to 1.0.

Final Thoughts:
This build has been tested and running on some "unbootable" tablets. This is not a guarantee this ROM will work on your tablet. Also this ROM is still going through the testing phase so there is most likely to be bugs. Finally, I have mentioned quite a bit about the 3.1 kernel. Right now this ROM is still running on the .39 kernel. This will change in the near future. We are still ironing out kinks in the 3.1 kernel and it is not ready for public consumption yet.

If you like this project and appreciate the extreme amount of time that the devs put into this please donate:

This ROM would not happen without all the brilliant minds behind the CM10 project.

This Is great, I can now run JB on BL 1.2 Great job dev team. Thanks.

[Mike West]

I know what I am doing tonight! And to think, my GTab will be running JB before by brand-spanking-new Galaxy S III!

In the install instructions you say, " Download the following file <--- Seriously don't skip this step unless you are 100% positive that you have a 350M system partition." Is the 350M a misprint because it is normally 250m?;-)

[rozelle25]

First, thanks to Team DRH.

I was going to flash but wigged out. When I connected my gtab to my computer it wasn't recognized (I don't remember if this is normal). So I couldn't transfer the download. No problem, I downloaded from the DRH app direct. I compared the instructions with 1.3 and then was worried that after I wiped partition my computer won't recognize my tablet in order to nvflash. Obviously I did this once before becuase I'm on 1.3 but I guess I just feel a bit rusty. Is there something I'm missing?

[chowhoundb]

Wow even the boot animation looks crisp and buttery. Great work devs cant wait to dig into it more.

On an ICS side note, I was goofing around with trying to update the initlogo.rle last night on 1.3.2, and was able to get one to flash properly, but then during boot up I just get the birds twice. Total guess at this point but it leads me to think that something changed in the code about either the reference to the intilogo or that the current logos we have are incompatible. I read on another thread that we are seeing the birds flash twice because the framebuffer is not being loaded with the initlogo so whatever was still stored in it (the birds) is being reused. I looked into logo.c but it appears to have not been updated in the past 6 months.

I will keep digging, but rusty programming skills are really holding me back.

It's not a misprint as it's further explained that Jelly Bean required the larger system partition. This is the same for my HTC Desire running Jelly Bean. Possibly the same reason why CM team decided to not continue support for HTC Desire and similar devices with small ROM(?).

i got an error downloading data from the android mar.. i mean google play store, it tells me there is some RPC error fetching from the server. I solved it by doing the good old market fix for the gtablet, clear data and force stop the mar.. i mean googple play, clear data for google framework services, reboot the tablet, enter market again, if it asks you to retry, go and clear data force stop market again and this time it should load and u can update or download apps from the market now

Download the following file <--- Seriously don't skip this step unless you are 100% positive that you have a 350M system partition
Is there a simple command to check the size in terminal emulator. My linux is incomplete but would something like df tell us the size? Sorry, I don't have my g-tab with me to test and when I get home my ice cream will be melting and my jelly beans will be rolling. I continue to be amazed at what it has been possible to do with this tablet. My only regret is that I don't have the skills to participate in it. Great job Team! Time to punch the Pay Pal button again folks.

[Amplify]

Great job team DRH! Can't wait to flash this later today.

Nope its not a typo. New Android = New system size

You can run the command

df

Then look for the system partition size.

When you go in df, list will say "system" then it will tell size .

flashed by following instructions to a 'T"...back to 350 stock and then DRH JB. No hitch so far and pretty amazing...great work

[desteele]

If we were "laggy" on ICS, is it going to be a similar experience w/ JB?

[deuce]

Did a clean install and this is a thing of beauty. Install went very smooth and I agree, the boot animation looks more crisp.
My YouTube has the same problem as always with the buffering but not a big deal.
Thanks Team

I found that with all the prescribed tweaks from the ICS thread, the 1.3 ROM would get laggy over time unless I cleaned the cache partition regularly. That said, in JB and 1.3.2 the cache partition is moved, so if it is still necessary I dont know if cache cleaner apps will work properly. Does the clean cache statup tweak in ROM control work for 5.0? If so I would suggest a manual reboot with this option if you feel lag creeping up on you. Seems to work well for me.

[djrakun]

Is "Google Now" functional? I know there are problems with the mic although it's been reported to work longer than 8 seconds on voip apps. Even without voice recognition, I'd like to play around with Now a little more. I loaded a ROM on my samsung fascinate and it's a lot better than i expected ( after being un-wowed by Siri and Vlingo and the like), but that phone is not a daily driver for me like the gtab.
