1.1 BL

Anyone tried this rom with 1.1 BL? Currently running DRH ICS that way. Only way I could get rom to load. Wondering how nvflashing to 350mb will affect me.
[G Tablet Android Development] lekhwani:
Thanks to the drh team.

I would like to ask how is the rom performance as compared to other ics roms? Why is this still called alpha when things equal to ics roms work?
[G Tablet Android Development] jheiselman:
Just wanted to say thank you to Team DRH. This build installed flawlessly on my G-Tab and it works great. Haven't tried the camera yet (listed as non-working anyway), but everything else is working without a hitch.
[G Tablet Android Development] Potimto:
Good job Team DRH, its teams like you who keep our faith in the tablet even though the manufacturer's have abandoned it. Just out of curiosity, does this rom fix the battery drain issue that seems to occur on every 2.2 rom? I havent the chance to test this out yet, but would be keen to if the current drain is atleast slowed :)
[G Tablet Android Development] lulonen:
How to male Play market working with this rom?
[G Tablet Android Development] jheiselman:
I have had it installed for several days now and can tell you that the battery life seems great. I've had my daughter playing on it for several hours and then I played a fairly intensive game (Major Mayhem) for about an hour and when I checked the battery after that it still said I had about 60% left.

Follow the instructions to flash the gapps package. I had to do it twice for some reason. After that, you'll have a Market app that once you launch it will eventually upgrade itself to the Play Store.
[G Tablet Android Development] Potimto:
Thanks, I should have worded it better hehe I meant the standby battery drain. If you put the tab on standby does it still drain 20+% overnight?
[G Tablet Android Development] Godzilla10:
Rom has been working great. Its fast and smoother than ICS but I can't get adobe flash to install from the market or see it it says its not compatible.
[G Tablet Android Development] Nospin:
Adobe pulled flash from the market for everyone but the UK, you will have to find it somewhere else.
[G Tablet Android Development] Nospin:
Anybody know how to disable the capacitive buttons on the side? Button remapper doesn't seem to be working (I set all the buttons to "Focus", but they still seem to be functional).
[G Tablet Android Development] gierso:
Nospin cover them with duct tape. And paint xD

Just kidding maybe the app remaper is not compatible with JB but its just a thought

I bought the tf700 but i still keep my good old gtablet :)

Its good to see that it still receives love :)

My Gtablet is VERY SLOW after update

Hi everyone.

After I flashed this rom.

My Gtablet have been almost unusable.

Everytime I touch an object I have to wait, what feels like a minute, before any interaction happens.

No Idea why this is.

Anyone out there who have any idea?

Thanks

[G Tablet Android Development] tsukaza:
You will probably need to apply the system tweaks posted in another forum which make JB runs smooth.
[G Tablet Android Development] firewater88:
I would also like to know where to find these. Are you talking about another device's forum?

I have done the normal tweaks and still have it super laggy.

[G Tablet Android Development] raywaldo:
GTab "tweaks"

Visit my guide. The tweaks are almost at the bottom of the article: http://raywaldo.com/2012/09/jelly-bean-on-the-gtab/

GTab “expert” Rajeevvp on XDA has suggested four things that can stop the LAG experienced by many who use this ROM. (http://xdaforums.com/showpost.php?p=28974462&postcount=619) Here are his suggestions (they work GREAT for me): Try these things to reduce lag:

In Settings > ROM Control (set on boot if you’re happy with)

1. Build Properties/ dalvik VM cache heapsize – reduce to 64M.

2. Performance/ free memory – set to 50MB.In Settings > Developer options (need to set on each boot)

3. Apps/Background process limit – Reduce to 2.

4. Apps/ Don’t keep activites – Check the box
[G Tablet Android Development] dp917:
I haven't tried this yet, but it was posted on the Galaxy Nexus board as a supposed fix for lag on cm10 based roms. I would think this fix isn't device specific.

Bootloop

I have just flashed over to the new Jellybean from Team DRH, following the instructions exactly from:

http://raywaldo.com/2012/09/jelly-bean-on-the-gtab/

This resulted in the aforementioned boot loop, so I booted into recovery, cleared Dalvik/Cache/Data and reflashed the ROM.

Same result...

Quick search on the forums here says to attempt to NVFlash ICS BL 1.2 first. I used this guide/download here:

http://viewsonic-gtablet-for-dummies...om/nvflash.htm

Flash succeeded, booted into TNT. I turned off Tablet, back to NVFlash mode, ran through the instructions for re-NVFlashing the 350MB system partition file using downloads from this location.

http://xdaforums.com/show....php?t=1850994

MD5 on the ROM checks out for my download.

Recopied ROM download to Internal SD twice. Same result

Tried with and without GApps. Same result

Booted it up with NOTHING plugged into it (power, USB, or even External SD card). Same result

Could it be I am not waiting long enough for the OS to initialize? It has been sitting at the birds for approximately 20 minutes.

Any help is greatly appreciated

You'll have to extract only the kernel from one of the older ICS boot.img files (try the one in the 1.5 version of G-Harmony ICS) and then insert that into the JB ROM. Do you know how to do this?
[G Tablet Android Development] firewater88:
Thanks guys. For some reason I had forgotten about the "S" forum.

Will apply those soon...
[G Tablet Android Development] deathcipris:
No. I am afraid I don't know how to do that, but my Google-Fu turned up.

http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images

Is this what you are referring to? Simply extract old ICS 1.5 kernel, recompile JB boot.img with said kernel, and place in the JB ROM zip?
[G Tablet Android Development] rajeevvp:
Yes.

You can use that perl script in your link, or do it using the gTab itself (let me know if you need the steps).
[G Tablet Android Development] deathcipris:
Unfortunately, that link for the perl file is dead so it looks like I may need to just do it with the gTab itself.
[G Tablet Android Development] rajeevvp:
1. Get one of pershoot's kernel update zip files for the gtablet. It has all the tools you will require.

2. Unzip this zip file into a new directory on your PC, then remove the entire system directory from within it--it's not needed on ICS or JB.

3. Now boot the gtablet into CWM; extract the boot.img file from the G-Harmony 1.5 zip file on your PC, then copy it to the gTablet:

C:\> [B]adb push C:\SOME\PATH\boot.img /tmp/.[/B]

4. Copy also the unpackbootimg program (got in step 2, above) to the gTablet:

C:\> [B]adb push C:\SOME\PATH\kernel\unpackbootimg /tmp/.[/B]
C:\> [B]adb shell chmod 700 /tmp/unpackbootimg[/B]

5. Unpack the boot.img file on the gTablet:

C:\> [B]adb shell /tmp/unpackbootimg -i /tmp/boot.img -o /tmp/[/B]

6. Copy the G-Harmony 1.5 kernel from the gTablet back to the PC, overwriting the pershoot kernel got in step 2.

C:\> [B]adb pull /tmp/boot.img-zImage C:\SOME\PATH\kernel\zImage[/B]

7. Create a new kernel update zip file by zipping everything up again. Make sure you keep the same directory structure (minus system, of course) in the new zip file too.

8. Reboot the gTab, then flash the 1.5 kernel update zip file immediately after you've installed TeamDRH JB 5.3.

Caveats:

Since this is an older kernel, some things like mic and camera support (external & internal), and the compressed RAM support for 5.3 JB may be missing. For the same reason, some of the JB related system tweaks mentioned on Slatedroid may not apply, but, the ICS tweaks in post #29 of this thread should still work.
[G Tablet Android Development] deathcipris:
Holy Toledo, Batman! It worked! It boots! ITS ALIVE!!

Thank you soooo much! I hope these instructions find others having the same problem and help them as they helped me.
[G Tablet Android Development] mikef:
Harder to find instructions in posts instead of threads.

rajeevvp, it you want to write this up as an [INFO] or [GUIDE] thread in the GTab General forum, I will add it to jerdog's IMPORTANT GUIDES FOR YOU & YOUR GTABLET stickied thread. Or I can copy the post above into a new thread there for you to start with if you like.

Thank you,

mf2112
[G Tablet Android Development] rajeevvp:
Nah... the info. is not that important: sooner or later this bug will go away and then the post won't be that useful. In any case, most developers already know this stuff, and, users don't need to fiddle around with boot images like this. I appreciate the offer, though.

There's no need for other users to follow the same instructions. Just post the zip file that you've created--which was the whole point of the exercise anyway.

Just edit the META-INF/com/google/android/updater-script file first and get rid of the 3 lines containing references to "system". Use a programmer's editor--something which preserves the current line-endings (LF--\n) --instead of something like Notepad which converts all of them to MS-DOS conventions (CRLF--\r\n).

**\\OFF TOPIC//**

Rajeevvp, would you mind taking a look at this thread about swapping internal and external sd cards: http://xdaforums.com/showthread.php?t=1422158&goto=newpost. I have looked at your suggestion and I do not feel advanced enough to attempt it. I was successful in doing it on my Acer iconic a100 tab and I asked the dev if it would work on the Gtab and he said it should but I would like for you to look at it first. I could not find the recovery_sh in /etc. I have not downloaded the zip file yet. Thanks

Hey you guys I had no problem flashing this ROM it works and it's responsive my one issue is I can't dl from the market or update the few apps that are on it please help. I get could not dl due to an error RPC:AEC:0
[G Tablet Android Development] rajeevvp:
Why do you want to swap SD cards? Is your internal one not working?

That script won't work on the gTab with DRH JB 5.3 for a variety of reasons:

a) the mount locations are different,

b) the device names may not be correct (I haven't verified this one), but more importantly,

c) no /etc/install_recovery.sh file exists, or, is called at boot, on any of the ROMs for the gTablet, so the script, even if installed correctly, will never run.
[G Tablet Android Development] renildrah:
Have questions.

1. Do I need to do steps 1-4 of the install process if I already have Clockwork Recovery installed?

2. I have tried to install this ROM twice now and I get the following error.

Magic value mismatch: .

'

Critical failure: Unable to start kernel.

Unrecoverable bootloader error (0x00000002).

Now, before each time I installed this ROM, knowing I already have Clockwork Recovery installed, I did wipe data/factory reset, wipe dalvik cache, then partition SD card 2048M/0M.

am I doing something wrong here?
[G Tablet Android Development] raywaldo:
Full NVFlash with 350MB system

The OP says that you must expand the system partition in order for this ROM to work. To do that, you should run the NVFlash in the OP. It will also update your CWM to the new (TeamDRH) version. It is a very simple process and it eliminates all the problems that you may encounter.

If you need assistance, here is a link to my step-by-step guide (with real-time video): http://raywaldo.com/2012/09/jelly-bean-on-the-gtab/
[G Tablet Android Development] lartomar2002:
Thanks, the reason I wanted to try swapping is that I read that we can not move apps to the external micro sdcard. How true this is I do not know. Not being as experienced with android I am afraid to try because I might mess something up. I have a lot of games that require extra data and it can fill up my internal emmc fast. I know I can put my movis and music and books on the external sdcard. And it has double the emmc at 32gb class 10.
[G Tablet Android Development] renildrah:
Ray,

I want to thank you for your video. It made me realize that holding down the PLUS button on the volume button was what I was needing to do to get into APX mode. Once I followed the directions correctly, everything went as smoothly as possible. My co-worker that has the Nexus 7 is now jealous over the fact that I now have a 10" tablet with the same Android version as him.

Change of subject, I'll re-read this thread and check out TeamDRH's web site but the only issue I've noticed is a little bit of lag time when I load an app or even when I am trying to type out a word.

The simple answer is to repeat the NVFlash and re-install the ROM.

[G Tablet Android Development] Naddict:
Your ROM has revived my lowly performing tablet...thanks for taking the time on doing this port/development :victory::victory::victory:
[G Tablet Android Development] rajeevvp:
I looked into this a couple of weeks ago for another user, and it seems to be a few bugs in the DRH ICS ROM build, rather than anything in the actual code itself, which prevents the moving of apps to the SD card. (I couldn't, however, verify my conclusions because to do so I would have to build the entire ROM, and I just don't have the disk space, or the CPU horsepower, or the time, to do a complete build.)

In any case, the move-apps-to-sdcard feature is a hack for devices with fixed-sized (and small) /data partitions (usually on NAND instead of on MMC cards). Its loss is not a big deal on the gTablet where you can resize /data to whatever you want.

The smaller games might put their data and support files in /data along with the game apk, but, all the large games that I've installed have automatically put their (very large) support files into /mnt/sdcard (the game code still lives in /data, of course). Additionally, since the move-apps-to-SD card feature only moves the apk file (and not the data or support files as mentioned before), you, generally, won't save much space by moving most of the games themselves.

On the gTablet, it's simpler to just resize /data. (And, if you really, really do want the external SD card to be mounted as /mnt/sdcard, you can just change /system/etc/vold.fstab using CWM. However, it's better to incorporate this swapping feature into the ROM itself--like in CM >= 7.1--rather than relying on hacks of this kind.)
[G Tablet Android Development] renildrah:
Would it be worth running this ROM through the kitchen and telling it to allow apps onto the external SD card and see how it reacts? Thinking about doing that tonight.
[G Tablet Android Development] nobe1976:
Wouldn't be much worth trying since you would have to change the updated script in Kitchen in order to do it. Just Partition the Internal SD Card 4096/0 would solve allot of worries.
[G Tablet Android Development] redhonker:

Followed every step in raywaldo's guide and got it up and running without any trouble. It boots up in about 1 min -- granted that I have not loaded it up yet but still very impressive. Thanks a lot!

A few questions:

1. Titanium Backup keeps complaining [Your system settings may cause problems. To correct this, go to your phone's Settings, then in "Applications" then in "Development" and tick the "USB debugging" checkbox"]. However, I can't seem to find this option. What should I do to get rid of it?

2. Gallery (1.1.40000) appears to not working (gmail and Market work fine). It does not even show any setting (blank screen). I restored Gallery 1.1.30682 from CM7 and deleted the DCIM folder and my Picasa albums do show up. Apparently these are different applications as they co-exist. But I can't find any update in Market. Is there a new application?

3. Is there any new way to mount a shared folder from a Windows PC?

4. Is there a way to disable the flash during boot up and reveal the actual actions (just like a Linux box)?

5. Where can I find Adobe Flash Player?

6. Is there a MP4 player?

Thanks
[G Tablet Android Development] generosity21:
1. This option is in different places depending on the ROM. Can't remember where it is right now, but check the settings categories, it's in there somewhere (developer/security/apps... somewhere in there).

2. Not sure. If the CM7 Gallery app works though, than it's all good right? I'm guessing you restored it to the user apps folder rather than the system apps folder, which might be why they can sit side by side. Or they could be different apps with different APK names, as you suggest.

3. Pretty sure you can do this with some of the file browsing apps (ES File browser, etc.)

4. Not sure, sorry.

5. Flash Player is not officially available in JellyBean. There are apk files floating around, search XDA and you should be able to find an ICS version of Flash and sideload it. Also, many browsers (including Chrome, ironically) won't support flash even if it is installed.

6. There are many mp4 players. Don't know if there's one included, but just go to the play store and install MX Player or Mobo Player.

Good Job

Thanks team drh for all your hard work and thank you raywaldo for a very helpful video!!!

The dev's instructions are great, but if someone is still a bit hesitant or unsure then just watch raywaldo's video guide which will take you step by step thru the process!!

If the dev finds the video helpful, he can perhaps add a link to it in the OP?!!
[G Tablet Android Development] redhonker:
1. Find the option for USB debugging under Developer Options

2. It's Gallery3D. However, the 2 Gallery3D under Market no longer works (same as the one bundled with JB). This one came with CM7 and worked fine. I guess the difference might be the camera?

3. Can't get Astro SMB to work. ES File Explorer is less desirable as you have to use a different manual. Can't get Cifs Manager to work -- kernel module fails. So still waiting on solution

5. Adobe flash player installed fine and the stock browser or firefox works. However, it seems SmartSWF is still needed for standalone swf playback.

TeamDRH Prep

Everytime I run the TeamDRH prep, it seems to gets stuck in APX mode. I have used NVFlash a number of times, in fact its how I recover from this mode. Not matter what I do, I get stuck in APX mode after the prep NVFLASH. Anyone else experience this?
[G Tablet Android Development] nobe1976:
You have got to remember that this prep doesn't install a system image. It will install only the bootloader, boot image and recovery. It was designed to boot straight into recovery after the prep is complete. There a very few woot sold devices where the volume rockers were put in backwards. So if after the prep is complete it tells the machine to enter into recovery mode (volume + & power trigger), but instead the device will go into apex mode (volume - & power trigger). Just power down manually and put it into recovery mode yourself. Other then changing some of the commands in the .bat file that is about the just of it.

Sent from my Smooth A$$ Gtablet
[G Tablet Android Development] rajeevvp:
This happens sometimes after a full nvflash step for some people. To recover, try:

1. Put back the stock recovery.

2. Copy a VS ROM update to sdcard and then install it using stock recovery.

The stock ROM installation process which writes a bootloader (and other NAND partitions), also tends to fix this always-boots-into-APX mode problem.
[G Tablet Android Development] markmac:
Thanks Rajeev. I was able to find a sure fire recovery method on another forum. In hopes of getting JB on my GTab I did try to run the prep again, unfortunately it resulted in the same APX bootloop. I was able to recover easily this time. Guess I am stuck on GB for now.
