My gtab boots 1.6.2 no prob. You may need to nvflash DRH prerequisites to make sure you're on a 250 mb system part. I have done this with all the drh and gharmony roms without any problems.
[G Tablet Android Development] dmahon:
Yeah, I know - a lot of people's boot it no problem. There's a smaller group of tablets that hang in the same way mine is. There's a couple posters on here who have reported the same problem, a lot more on the DRH lists. Unfortunately it's not so easy a fix as nvflashing the right thing first, or clearing the cache or something.

I can run 1.6.2 w/ the boot.img from 1.5. It runs great, I'm pretty happy with it, so if that's as far as I can take it, I'm okay with that. I'd love to be able to always load up the newest latest, but if not, I'm not going to kill myself over it. I'll keep trying new releases as they come out, though, in case whatever is broken becomes fixed.
[G Tablet Android Development] rajeevvp:
I would careful about using that.

A 350 MB system partition entails a much reduced cache partition on the NAND flash, and, if the contents of cache haven't been "moved" to the /data partition--like in the TeamDRH ICS 1.3.2 and JB Alpha ROMs--then you're risking unpredictable behaviour in the future with the current ROM.

I just downloaded SU from Google Play, rebooted

this message brought to you by my GalaxyS3 running Phantom's Blazer
[G Tablet Android Development] BoT@XDA:
i didn't go thru the whole thing but has anybody experienced wifi issues with the 1.6.2? i flashed back and forth between 1.5 and 1.6.2 and wifi works in 1.5 but not in 1.6.2.
[G Tablet Android Development] docsparks:
Right here. Have completely wiped, and even nvflashed. 3 times. Wifi signal shows strong when booted after rom install, when i connect it just sticks on obtaining ip addres, signal drops to 1 bar, and it never connects. bums me out - advice?
[G Tablet Android Development] BoT@XDA:
it' says something like: "avoided because of slow connection" or something similar but not connecting at all.

No luck with 1.6 but 1.5 worked first time

OK, so I tried repeatedly to get 1.6.2 working (160 Supercharged).

No joy.

I followed all the steps (AFIK) - upgraded to the 1.2 bootloader, did the DRH Prep 250 NVFlash step, partitioned SD-Card etc. etc.

It kept dying at the 3 birds, although inconsistently. Sometimes it would just hang there, sometimes the screen would flash a few times before hitting a black screen, sometimes only once. But the ROM never booted.

So, I went and downloaded Clemsyn Caulkin Froyo v8, but before I flashed it, I thought I'd try v1.5 of this ROM for the hell of it. It worked :)

Not sure why 1.5 should work for me, but 1.6.2 not.

I don't know if this is relevant, but I always got the random offset message when flashing 1.6.2.

[EDIT] I also get the message when flashing 1.5 which works, so I guess it's not relevant.

Then I thought "Hey, I'm going to try re-flashing 1.6.2 now to see if getting 1.5 working has made a difference somehow."

Nope :(

So, back to 1.5 again. Worked first time (again).

Looking forward to trying the ROM out - it seemed pretty snappy getting through setup and for the few seconds I messed around after I got to the dashboard :)

Thanks tjohnsonjr!!

---------- Post added at 02:29 PM ---------- Previous post was at 01:56 PM ----------

I tried downloading 1.6.2 again, and this time it came out to only ~78Mb.

According to the browser it was finished.

Could it be that the site hosting the download is just screwing this up for everyone?

Surely it wouldn't flash at all if the ZIP was incomplete?!?!
[G Tablet Android Development] skyforces:
download file

does anybody has the G-HARMONY ICS v1.6.2 V6 Supercharged(160 density). the original website is updating and i can't download the file.
[G Tablet Android Development] jazzruby:
If you have the 120 density zip file, the only difference is 1 line in the build.prop

You can change it manually, the file is located at /system/build.prop

ro.sf.lcd_density=160 < change to 120

Thx i will try that.

Can't see phone WiFi

Was playing with my GTab running 1.62 supercharged, at a meeting where someone had an iPad, and people were questioning if it was worth the extra $850. This is a pretty, fast, and smooth rom. Nice work.

However, here's a wierd one. I can connect the GTab to my verizon or dir601 running DD-WRT as a bridge, but it can't see my HD2 running JB PA and Barnacle wifi tether.

I can see and connect two different laptops (Acer & Toshiba) to the HD2 with Barnacle tether without issue.

Any ideas on what I did wrong, or how to fix this?

Is there a fix or a app to fix battery percent
[G Tablet Android Development] nobe1976:
A little bit more information on your question.

Do you mean to mod the battery status? No unless the OP can create a deodexed version of the rom then maybe.

Do you mean a app to calibrate the battery? Yes check the Play Store there are different free versions but only one that I have used that works great. Just do a search in the Play Store and you will find it "Battery Calibration". You can also just use CWM to clear battery Stats also.
[G Tablet Android Development] Enmi:
Ok, so I started from scratch after playing with TeamDRH Jelly Bean (still as sluggish as their ICS release) and NVFlashed back to stock, flashed the rom and cleared caches. I let it sit for an hour, and even before signing in or restoring apps from backup just in case, it refuses to connect via USB properly. Restored apps from backup with ROM Toolbox, and the tablet will not connect as a media device as it should.

It crashes / freezes my file manager, explorer and gnome nautilus alike. Arg!

I love how fast and smooth this rom is, but that's really infuriating to not mount to a PC properly.

Anyone has any insight into what may be causing it? I'm not sure how I'd be able to get a logcat if that can be useful here.

Anyone else experiencing this?

Thanks for any help on this, I'd love to be able to get USB mounting going on this Rom!
[G Tablet Android Development] tjohnsonjr:
You can also boot into recovery and transfer your files that way.
[G Tablet Android Development] skyforces:
Thx i will look it up.
[G Tablet Android Development] Enmi:
While it solves the immediate problem, it's not a real solution. :/

Not to mention the fact that usbsticks and memory cards (microsd) are mounted readonly on this rom.

I cant write data to external memory on this tablet. It works fine on any other rom.
[G Tablet Android Development] rajeevvp:
It's a battery hardware problem with no known fix at present.

See above. As the battery ages, the RSOC % displayed at full charge will decrease. No app is going to fix this on the gTab.

It's a myth that clearing battery stats will fix battery calibration problems. Google's own engineers say this.
[G Tablet Android Development] nobe1976:
I read the link that you posted and much thanks on passing the knowledge. To my understanding is that when erasing the Batterystats.bin file all its really doing is after a complete drain and fully recharging allows the UI to read the battery level properly. Mainly done when flashing different roms in one period. I didn't mean that it will clear the actually lifetime of the battery.
[G Tablet Android Development] jazzruby:
Deleting the batterystats.bin has no effect on battery level, this value is read from hardware.

The batterystats.bin provides app usage statistics (cpu, gps, wakelock, etc...) to the Settings > Battery UI and maintains these stats across reboots.

After a full charge and disconnect from charger the batterystats.bin is reset.

The reason it exists in recovery (wipe batt stats) is to start a fresh reporting of app usage statistics and not app usage stats that may be irrelevant to or apps not included in the ROM you're flashing.

[G Tablet Android Development] redhonker:
choice of ICS 4

I've never really understood the different variants of ROM for gTablet. I am currently running CyanogenMod 7.0. This one mentions G-Harmony, which is in CyanogenMod build name. Should I go with this one or DRH (looks like the only other option)?

Thanks
[G Tablet Android Development] rajeevvp:
Correct. Most usually after you've upgraded the ROM.
[G Tablet Android Development] jazzruby:
Hi redhonker,

Maybe I can shed some light; the CM 7 ROM -as I'm sure you already know- is based on Android 2.3.7 (Gingerbread). The reference 'Harmony' is the NVIDIA platform used by the gTablet and a few other Tegra II devices.

G-Harmony is built from source -Android Open Source Project (AOSP)- and is based on Android 4.0.4 (ICS).

Team DRH has (I believe) frozen their developement of ICS to focus entirely on JellyBean; which is now their 'flagship' ROM.

So, in summary, with the ROMs you mentioned, you have 3 choices of different versions of Android

CyanogenMod 7 - Gingerbread

G-Harmony - Ice Cream Sandwich

Team DRH - Jelly Bean

HTH,

-JR-
[G Tablet Android Development] redhonker:
Thanks for the info, JR. I guess I should go with G-Harmony ICS.

Is there a detailed instruction (like the one for DRH) on the upgrade process? And what's the difference b/w 160 and 120 density?

Thanks
[G Tablet Android Development] jazzruby:
Your welcome,

A system of 250 MB is required and you can use the NVFlash pkg from DRH ICS thread to obtain it, then do full wipes (factory reset) and format system in recovery (mounts & storage) prior to flashing G-Harmony.

Density - 120 would be the norm for most, however, icons; i.e. in app drawer, text, etc.. are very small, 160 'blows up' the UI globally and may be good for weak vision; I find the 160 too much and am using 120.

The diff between the 2 (120 <> 160) ROMs is a build.prop edit, so whichever you download/flash you can experiment with the 'Density' as follows:

Navigate to and open the fie > /system/build.prop

Find and edit the line:

ro.sf.lcd_density=160 < change value to 120 or 160

-JR-
[G Tablet Android Development] redhonker:
Sorry that I am not too comfortable doing this type of work -- I can follow instructions though.

Here is the instruction from DRH thread. Looks like I need to download NVFLASH to create 250M system partition. Do you know I can check the current size?

Boot into current version of CWM and "Wipe data/factory reset"

Partition Internal SD Card (2048M/0)

Turn tablet off

Download the following file <--- Seriously don't skip this step unless you are 100% positive that you have a 250M system partition

NVFLASH the file following the instructions that are included for Windows/Linux users

Upon reboot of tablet let T&T fully boot and then shut it down

Reboot into recovery

Flash the Rom/Gapps

Enjoy

Here is the steps I followed to install CM 7. Will this work?

1. Clean your MicroSD card or delete the update.zip in the internal storage from Objective 1 (installing CWM 0.8)

2. Create a folder called ROMs on your internal storage.

3. Copy the gharmony.zip/yourrom.zip to the ROMs folder you just created. (Do NOT unzip the file. CWR uses .zip files. If your file has an update.zip in the original zip file (ie. tnt lite 4.20has an update.zip inside of the gtab_tnt_lite_4.20, rename it to romname.zip or something for easy identification.)

4. Power off your device.

5. Boot into ClockworkMod.

1. Press the power button and the + button at the same time until you see "Detect a recovery key pressed”. Release the buttons and your device will boot into CWR after a few seconds.

6. Backup your device

1. Go to "backup and restore"

2. Highlight "backup" and press the home button. (This will take a few minutes depending on your data)

3. You will now be able to go back to the stock ROM if you mess up the rooting process.

7. Go to "mounts and storage"

8. Highlight "mount/system" and press the home button. It should now say "unmount/system"

9. Do the same for "mount/data". Will say "unmount/data" if done correctly.

10. Press the back arrow to return to the main menu.

11. Flash the ROM

1. Highlight "install zip from sdcard" and press the home button.

2. Highlight "choose zip from sdcard" and press the home button.

3. Highlight "ROMs" and press the home button.

4. Highlight "G_Harmonyv1.2.zip" or "yourrom.zip" and hit the home button.

5. Highlight "Yes - Install yourrom.zip" and hit the home button.

6. Once the process is complete you should see something like "Install zip from sdcard complete" at the bottom of the screen.

7. Press the back arrow until you return to the main menu.

12. Highlight "mounts and storage" and press the home button.

1. Make sure /data and /system both say "unmount". If not, mount them the same way as steps 8 and 9.

2. Press the back arrow to return to the main menu.

13. Highlight "wipe data/factory reset" and press the home button.

14. Highlight "Yes – delete all user data" and press the home button. (You MUST do this for the ROM to run correctly. If you do not, it may cause a boot loop.)

15. Highlight "reboot system now" and press the home button. (Be patient for the first boot up. It can take anywhere from 5 - 15 minutes)

Thanks
[G Tablet Android Development] jazzruby:
@redhonker

Don't sweat it, NVFlash is not as difficult (scary) as it sounds and is basically an 'easy as 1, 2, 3' kinda process

Open/Run Terminal Emulator and type: df then Enter/Return to see the size of your 'system', 'data', etc...

The NVFlash will do (among other) 3 things: (1) install 1.2.bootloader (2) grow the system partition to 250 MiB (3) install a 'proper' -updated- ClockworkMod recovery.

You can skip the booting fully into Stock TnT and boot straight to recovery and do the wipes and format and then flash G-Harmony.

HTH and have fun!

[G Tablet Android Development] schwinn8:
Just installed this on my Beasty GTab. I had bad luck/performance with DRH ICS, so I was afraid to use it... but I was sorely mistaken. The ROM installed easily and is already running. It was "TOO" easy.

In addition, one of my wife's apps that she wanted wouldn't work on DRH ICS (an earlier Beta, admittedly). The app is for magazines called NextIssue. The good news is that the app appears to be running well, without the graphical issues I saw before. Excellent.

It's a fresh install, and I think a little more tweaking (and settling in) is needed, but this is a great start so far. Thanks for the excellent ROM!

EDIT: Extra comment. The 120dpi version was rather small, but looked good. Unfortunately, the Amazon app store would not render properly at this resolution, so I tried switching to 160dpi via a build.prop edit... but then the tablet wouldn't boot up. Even a cache/dalvik wipe didn't help. So, I reinstalled the 160dpi version over the 120dpi install, and now it's fine and running again...

EDIT 2: I don't need the japanese keyboards in there, I presume I can safely remove them with TiBu?
[G Tablet Android Development] tjohnsonjr:
Thanks. I'm glad you like it. You should be able to remove the Japanese Keyboard. I forget the name of it off the top of my head but you won't have any problems removing it.
[G Tablet Android Development] schwinn8:
One more question - the postings say Google Now is included in the release, but I don't see it? I also can't seem to "Swipe up" to get it to activate? Is something missing?

EDIT: Nevermind. Found it. It's activated by clicking the first "Google" word at the top of the home screen...
[G Tablet Android Development] s9amme:
is it normal to have only 259kb left on the system ROM partition? I can't update my hosts file for ad blocking since there's no more space left. Maybe I just need to delete some system apps I don't use.

I am on a 250MB system partition, by the way.

EDIT: Deleted some system apps that I don't care for, got my system partition up to 11MB free. I was able to update my hosts file now.

I noticed brightness adjustment isn't working

This ROM is very smooth and responsive so far. Much like froyo back in the days. Been trying out a bunch of ROMs over the past week, I think this will be my daily driver. Great job on this! Thanks
[G Tablet Android Development] schwinn8:
ROM is running relatively well, for the most part. But I'm seeing a huge slowdown right after waking it up. For one thing, it seems to disconnect from wifi even though I have set it to "never" disconnect.

But beyond that, like I said, it's crazy slow after being asleep. Almost as if it's "hibernating" and has a ton of things to do when it wakes up (my windows pcs do this). Is there any way to prevent the disconnect and slow behavior when woken up?

I'm tinkering with v6supercharge settings as well as setcpu settings (raising the min) to see if that helps. And real advice is appreciated.

To the previous poster, I had a similar issue the first time I installed. I used recovery to wipe /system (via advanced menu) and that helped remove some scraps that appear to have been left in there. I'd suggest trying that next time.
[G Tablet Android Development] kank_fraud:
Its a great ROM

Fast UI and overall response, but some applications keeps crashing, like games and all.

I am using this in the Malata Zpad T2.

Will it be possible for you to use the full 1GB RAM available in Zpad T2.

Or if possible for you to teach me how to or direct me where I can get more info about it.

I have searched how to, but I cant find any info, or forum disscussions or anything as such.

If any help, would be greatfull.

The ROM is towards the right direction.

The new JB ROM released by TeamDRH has 199MB of free RAM, which actually help apps to be more stable, but otherwise its still in alpha, kinda slow.

Samurai vs Zombies crashes after few seconds of play

Was running TeamDRH JB 5.3 previously and everything run ok with it.

I was unable to install DRH's 1.3 because I kept getting the birds loop,

so I went with G Harmony 1.5

Since I see that 1.6 is using DRH's 1.3 kernel do you think if I try to go to G Harmony 1.6 that I will start getting the birds loop?

I mean right now it's running, I'd love more stability / features / speed, but.... I dont want to spend a day or 2 trying to upgrade only to fall all the way back...
[G Tablet Android Development] tjohnsonjr:
1.6 should install fine. The only way to know is to try.
[G Tablet Android Development] heinrich:
This is a very good ROM! Stable, and all my apps and kids' games work perfectly. Thank you :)
[G Tablet Android Development] NiNJA_ONE:
Let me just say - thank you to the OP for this. ODEXED is indeed the best - i've not even applied supercharge, and its the most stable rom i've seen to date. No slowdowns. i'm on loader 1.2 partitioned @ 350.I love Team DRH but their Roms are not as stable as id like. For now this one will run the show until another stable update from DRH.

This Rom is BOSS. If you are having issues, clear your tab as in the OP and start over, you're doing something wrong. Excellent ROM!

Forgot to mention its RIDICULOUSLY fast! - FYI DO NOT use Go Launcher Tablet on this though, Go Launcher is garbage and will freeze your tab.
[G Tablet Android Development] hikouka71:
ok, have tried twice now flashing, everythings fine except i can't get wifi to connect, it sees my accesspoint, attempts to connect up to 'obtaining ip address' and just sits there, everything is correct and it wont connect, nor will it connect to my galaxy in hotspot mode... followed these directions the second time after multiple wipes just to be sure

i was coming from flashback HC rom, any ideas/help would be greatly appreciated

the tab runs much better now (including way faster boot up) but not getting into wifi is obviously an issue

also on first boot, it doesn't go into the initial setup it has a pop up asking me to select which thing to run, and as just once or always, it has some android.com item, and google startup i believe it said. did that on both flashes

Having sound issue, the sound stop working and need a reboot to fix.
[G Tablet Android Development] nobe1976:
Alright finished loading up the 120 version update. At first had issues with market downloading apps, needed a file manager to load some apps and test su. Ended up rebooting into recovery, clear cache and dalvic also fix permissions. During the reboot optimized apps and everything went smooth. Market started downloading once UI finished loading. Also ES file manager works and I changed launcher to Apex since that helped out during testing of DRH 1.1. Very well good port. Going to a bit more testing and report back later. Google Chrome works just about the same as on DRH build, but at lease it works.;)

Quick question regarding this rom:

I'm assuming that HDMI out isn't working?

If I follow correctly, this is more of a kernel issue, rather than a ROM issue?
[G Tablet Android Development] the3dman:
Correct HDMI is a kernel issue that is being worked on. The 1.1 kernel does not have that working.

Downloaded and installed - install went well

Initial setup went well, restore of apps is working, root is good, Citrix remote access works. Still to finish setting up email, Talk, Skype etc and try playing a movie and music.

Major thing so far has been general sluggishness when opening apps, downloading from Play Store, browsing. Boot up took 40 sec. as well

Maybe I have a dud Tab?

Edit: tab just reset itself and is stuck on the Pin unlock screen... Won't type pin and holding the on/off does nothing - time for the DRH?

Edit 2: ran battery out and was able to reboot. Tried rewiping and repartioning, but then started getting offset error and couldn't boot into ROM. (Seems like I generally managed to stuff everything...) So ran the DRH process from scratch, successfully loaded and ran DRH but it would randomly reboot. Have gone back to G-Harmony GB and all is well again
[G Tablet Android Development] markmac:
I blew the dust off my GTab to try this ROM. Unfortunately I tried both the 120 and 160 versions and both gave me an Offset message during install, but said install did complete.

You need to load the 5504 ROM which increase /system to 250m, you can get that using the ICS DRH thread.
