So, I've had a hell of a weekend with my Gtablet. I Decided to try out CM 7.0.3, but it got stuck on the word "Android" screen on first boot. I tried going back to Vegan 7 RC1 but it boot looped on first boot. I learned how to NVFlash back to stock, then installed 7.0.2 stable because from reading I thought maybe since I didn't have 7.0.2 installed the first time and upgrading to .0.3 was what caused my problem in the first place. It installed wonderfully, but when I tried to installed 7.0.3 it got stuck on the word "Android" screen again. I tried to NVFlash again, but it boot looped. I tried the NVFlash format open to erase everything, but it still boot looped on stock. Then I found that I needed to partition again, so I installed CW from sdcard2 and partitioned to 2gb/0. This time NVFlash worked great, but the OTA 3588 update wouldn't installed. I manually installed 3588 and that's where I'm at right now.
Also, before installing any new roms I always wipe data, cache, and dalvik through CW.
Sorry about all that, I just wanted to get it off my chest
Before I install a new rom, I'm curious about something. In this sticky http://forum.xda-developers.com/showthread.php?t=865245 it says to mount /system and /data in CW before installing the rom. None of the other write ups say to do this, and I was wondering if it's necessary?
Also, do you all wipe data, cache, and dalvik before AND after installing roms?
I'm just looking for some tips so I don't have to do all that NVFlash crap over and over again.
Thanks!!!
Having similar trouble
I have been trying to install Cyanogenmod 7.0.3 - I have been running VEGAn Tab 1.0b5.1.1 for some time.
I wiped every thing possible; cache, data, system, Dalvik...I formatted data and system...I tried repartitioning to 4096 and 256, then back to 2048 and 0....
All I get on install is the Viewsonic splash screen. It is a bit strange. I can wipe and reinstall VEGAnTab without issue. It seems that I can run Froyo based ROMs but not Gingerbread based ROMS...
Any thoughts?
I'm not pro, but think this might help:
I think Vegan 5.x is built off Android 2.2 while Vegan 7.x and Cyanogen 7.x are built off of Android 2.3. From everything I've read this weekend it seems that anything that was built off of 2.3 doesn't play well until you NVFlash back to stock and update to stock 3588. I think it has something to do with the way stock partitions stuff, but I can't remember for sure. So, if I were in your shoes, I'd do this:
1) repartition to 2048/0 in CW
2) follow this guide to NVFlash it back to stock http://forum.xda-developers.com/showthread.php?t=861950
2a) the guide is pretty easy to follow, just make sure your tablet is fully charged in case you have problems like I did. Also, make sure when you unzip the files into the NVFlash folder that they all end up in the same folder. When I did it one of the zips extracted a NVFlash folder inside the NVFlash folder, so when I double clicked on the .bat file to start everything it didn't work.
2b) Optional, in that guide there's a link to this post which wipes everything out on your tablet using NVFlash. If you decide to do this, do it before step 2.
3) sign into wifi and install the over the air 3588 update. Mine failed so I had to use this guide to install it manually.
4) install clockwork mod and roms the way you normally would. (this is the step I'm on, but I'm waiting for a reply just so I don't have to do all that crap again ) I think it'll work just fine though.

It might be the bootloader
i remember having a hell of a time with this. i had a 2.3 rom on my gtab and decided to start clean and i used NVflash and suddenly no 2.3 rom would install. the thing i did different was use the Full wipe zip file that erased ALL partitions, because nvflash doesnt do that on its own. try flashing this (replace nvflash files with whats in the zip file. DO NOT INSTALL WITH RECOVERY), which should flash you to the 1.2 bootloader. i dont claim to be an expert but its worth a try and you can always NVflash back. also you might want to check out the NVflash post again they updated the files used.

here's what i do after initial ROM install (Vegan RC1 or CM7) -
-power down tablet
-boot into CWM
-install zip from sdcard - choose downloaded GB kernel (the zip file that is under this heading on pershoots blog - "ViewSonic Gtab/Malata Zpad (Gingerbread):" )
-wipe data/factory reset
-wipe cache
-wipe Dalvik cache
-reboot system
don't know what i'm missing, but i'm indeed curious about your 2 questions, and i couldn't find a clear reference anywhere explaining this...any help from anyone will be greatly appreciated!! thanks!!

I'm working with my new (from woot) Viewsonic G Tablet.
I managed to flash clockwork recovery (v .8) with little to no trouble. However, I am having some difficulty flashing a custom ROM. I have tried several different versions, including many of the ones posted on this forum.
Whenever I try, clockwork says that the install completed, but when I reboot it hangs at the Viewsonic bird-logo screen. After about 25 minutes I give up, reboot. It happens again. I reboot into clockwork and restore to stock and it works fine. I don't think I'm missing a step, but I'm pleading for help.
From clockworkmod -- Wipe Data, Cache, and Dalvik Cache. Repartition sdcard to 2048 and 0. The repartition will format your user partition, so back up any data to an external source that you don't want to lose.
Re-flash ROM of choice, hopefully boot all the way, if not then try wiping data again after flash and then fix permissions from clockworkmod.
I'll give it a shot!

No luck.
My steps:
1) Shut down
2) Boot into recovery (hold the vol+ and power)
3) Wipe data/factory reset
4) Wipe cache
5) advanced, wipe Dalvik
6) advanced, partition sdcard 2048, 0
7) mount usb, copy rom & gapps over (both from xda with reports of success)
8) install zip from sd (CorwinCM7RC4Beta.zip)
9) install zip from sd ( gapps-gb-20110307-signed.zip)
10) re-wipe data
11) rewipe cache
12) rewipe dalvik
13) fix permissions
14) boot & freezes at the birds

Can you flash a stock rom like 3588 and see if that boots?
Stock roms are here:
http://forum.xda-developers.com/showthread.php?t=842000
They have to be flashed with stock recovery, not clockworkmod.
I would probably use nvflash to get a working stock image on it first. This thread for those instructions:
http://forum.xda-developers.com/showthread.php?t=861950
Nvflash bekit's images then flash 3588 through the stock recovery, and you'll be back to latest stock image. Then you might have success with the custom ROM again.
Some tabs had a slightly different partition structure, mine was one of them. I nvflashed bekit's originals and it straightened out some things for me back in December.
It seems like a lot to do, but you may only need it once. I've only needed to use it twice since owning the Gtab, and the second time was by choice.
Having similar issue on the batch recieved from woot. Stock and Vegan 5.1x works but everything else gets stuck at the viewsonic birds screen.
I have no idea why. I'm going to try to do the old nvflash push method of installing cw .8 bekit today, since on the two I had in my possession this weekend got stuck and I used the install via recovery on cw .8 on them.
(btw. My original tab loads any rom(g-tablet) i want to throw at it, I used nvflash in december so it's the only thing i can think of)
Model on the tabs from woot is upc300-2.2 so yeah I am baffled (unless it turns out the way cw .8 installs....)
I am using bekits v2.5.1.1 0.8 clockworkmod and when it try and do a factory reset...I can wipe the data...however when it gets to wiping cache....it just hangs and doesnt move....I have tried going into partion...set it to 2048/0 wiped everything......still cant get past wiping cache....any suggestions?
You could try to nvflash partition #12 (it's the cache partition) by edititing the nvflash format package but I sugest you restrain from formating the whole thing...
Moved to Q&A.
error i am getting:
backing up cache and formatting cache hangs indefinitely
I am having the same problem. I can't backup either since it hangs on cache. Were you able to fix this?
I am thinking of using NVFlash to restore to stock and then start over, but I was hoping to avoid this. I haven't used NVFlash yet and am concerned that I could make things worse. My G Tab is running Vegan Gingerbread edition and seems to work fine, so this is only a problem if I want to change things.
I started with TNT Lite, switched to Vegan (earlier version), and then back to TNT Lite before I installed Vegan Gingerbread. The backup worked originally, but not with the lat install of TNT Lite. Could I ave corrupted something when switching ROMs? If so, why does my G-tab still work? Maybe it is ClockwordMod that is not working. Is there another app I should try to fix the cache partition with?
Does anyone know if a full restore to stock with NVFlash will fix this?
So...I can't install either of the two CM based ROM's I've downloaded. However, on the first try, I installed VEGan, and then tonight TNT Lite, with no issues. Any CM ROM I try to install just sits on the loading screen, regardless of how long I wait. Is there something special that needs to be done to install them, different than what I do for other ROM's? (Clear data/cache, flash the ROM, clear data/cache again, reboot.)

I believe you have ClockworkMod 0.8 recovery, since you were able to flash Vegan Rom.
In general, before you flash the different rom
1. Back up your current rom
2. wipe data (factory reset)
3. wipe cache
4. flash the rom
5, flash gapps
6. reboot
Hope this helps
There have also been some reports of G-Tablets coming out of the box with incorrect partitions.
Using NVFlash has cured those issues. You should then be able to flash CM7 Roms through CWM like everyone else.
I repartitioned with 2048/0, shouldn't that rule out any partitioning problems?
I'm trying it again right now with flashing the rom then gapps.zip, waiting for it to boot...or just stay on the boot screen.
Format system and data, then follow those steps again. I ran in to similar issues when I hadn't formatted.
Also, do the three wipes again after installing the ROM and gapps.
Holy crap! I see the CM boot screen now! Thanks for the help guys. Now, do I still need to do the market fix (http://forum.xda-developers.com/showthread.php?t=865245)? It looks like from their changelogs that the latest version of Flash is cooked into the ROM so I shouldn't have to do that part from the guide, but I'm wondering about the market.
Well, the market seems to have everything, including an app (power control plus) that none of the other rom's let me see, so I seem to be good to go! Thanks again guys!
Thanks for the suggestion - and I'll readily admit I'm WAY out of my comfort zone with Android.
When I format the /system /data do I have to mount first?
What order do the steps run in? Do I partition and then format /system /data?
cannot install cm based roms
I was trying to reset from factory rest but failed when my gtablet stucked and apparently did something wrong along the way. Now when I turn it on, I get the 3 birds screen, followed by G-Tabdevs screen, then dead. I do have clockwork mod installed on it.
1 when I clicked factory rest, it just return to the manue and said cannot find the file.
2 when I did a back up, it went through boot image,recovery image,system and then taskbar stopped in the half at settings.apk and then dead.
3 when I tried to followed this link http://forum.xda-developers.com/showthread.php?t=865245
to use the external tf card to flash, Gtablet doesnot recogonize the external card, while I can read all the files in gtablet. I can copya single small file but cannot paste a recovery and update.zip on gtablet. Each time I copied a file from gtablet, then it is dead. I have to return on by pressing power and volume+.
4 I tried adb to push update.zip to gatblet,also failed. I feel my gtablet can only allows me to read it and refuse me to do anything on it.
Any ways to reboot my gatblet brick?
Please help! I've been reading forums all weeks trying to figure out how to fix it and am not having any luck!
Appreciate any suggestions
I have tried several different Rom Managers without a problem on my G Tablet. Have been using TNT lite. Recently I switched to Vegan Gingerbread edition, but when I went to backup my old Rom (TNT Lite) the backup hangs on backing up the cache. I tried wiping the cache and formatting the cache, but it always hangs indefinitely.
I installed Vegan Gingerbread anyway and it appears to work perfectly, yet I still cannot backup the rom with Clockworkmod (always hangs on the cache). If I try to look at the cache partition in filemanager, it shows empty, though I am not sure it is actually recognized. I can't seem to do anything with the cache at all.
I am, by no means an expert, but have had no problems with this before. Backup did work before the recent problem.
Since everything is working with my G Tablet now, I am not sure there is an actual problem with the cache, except that I can't backup the Rom without it hanging on the cache. This may limit my ability to load other Roms in the future.
Please help.
I have the exact same problem. I've had no issues backing up and restoring ROMs myself, but now I'm having issues with my tablet not being able to format or restore cache. I can install a ROM, but it takes a long time to actually load up - it can sit on the first splash screen for easily 5 minutes before it boots into the ROM, wher as before it took around 1 minute or less. Are you having this slow boot problem as well, or are your problems strictly with the cache? I'm going to continue to look into it (currently looking into using nvflash to do a restore and see if that irons things out), so I'll let you know if I come across any solutions. And please, let me know if you do as well.
hey guys i had the exact same problem before but nvflash fix what ever the problem was and the newly installed cwm work as it should. are you getting "ANDROID" screen right before it goes into cwm?
I am not getting the Android screen before ClockworkMod, but I generally boot with the power/vol + combo. I also have not changed Rom's recently, so I am not sure if this would be a problem or not. I do not have any boot problems that I am aware of, nor can I see and performance problems resulting from my inability to format the cache. The only problem is I can't wipe the cache, backup the rom, or format the cache as it stops on formatting cache partition and therefore can't continue the backup process. Other than incomplete backups I am not sure what problems this actually causes. Do you know.
I haven't used NVFlash yet, but I guess I will have to give it a try. Am I simply restoring the ROM to factory state and starting over or is there some other process I am looking for? Unfortunately, I did not get a proper backup of my original factory rom, so I will have to rely on downloads. Any tips on NVFlash would be greatly appreciated.
It's Fixed! Thanks for the tips.
Here is how I did it:
Ran NVFLASH - it was much easier that expected. It fully restored the original stock Rom, but I still had trouble with clockworkmod. Mostly it would not boot into recover mode. I then re-rooted the tablet using the Update.zip method, Then everything worked fine including backup and cache format.
I continued to restore my tablet and tried the backup each step of they way.
I installed Vegan Gingerbread - Worked flawlessly
I reinstalled MyBackupsPro and all my apps and Data - Also, worked flawlessly
I reinstalled Rom Manager - also worked flawlessly.
I used Rom Manager to upgrade ClockworkMod to 2.5.1.8 - then the backup/ format cache problem reappeared.
I then ran Rom Manager again and selected flash alternate ClockworkMod. It restored version 2.5.1.1. Then the backup and format cache worked again.
It appears that my Gtab does not work properly with Clockworkmod ver 2.5.1.8 and that was the entire problem.
Since Version 2.5.1.1 works great, I see no reason to upgrade this again and consider my problem fixed. I hope this info helps others
I've had Android on my Touchpad 32G for quite some time now, both CM7 and the latest CM9 alpha.
Recently I wanted to upgrade to the official nightly, so I downloaded that, Gapps, Rohans tweak and various other small things and was ready to go.
I did a wipe/factory reset, wiped cache and dalvik as I usually do.
Then I tried to update to the nightly, however it just rebooted my Touchpad.
When it starts to install it shows the usual "finding package...", "opening package..." and "installing package..." but when it gets to the "installing package..." part it freezes for a second and then reboots everytime I try it.
I have both CWM and TWRP, and TWRP now refuses to run. I can select the option in moboot and it is actually trying to run, and even go as far as showing the splash that is supposed to "roll up", but then it reboots just like when I try to flash a rom.
CWM works perfectly as well as the original webOS 3.0.5 installation.
I have tried clearing the uiImages from /boot (using webOS and classicnerds cleaner) which doesn't solve my flashing problem.
Now, upon flashing any new rom, it always reboots as per the description above.
Any solution to this? Help would be much appreciated.
I have created a 4GB partition for Ubuntu chroot that can be started from within webOS.
Does creating that partition break the ability to flash?
It was created using Tailor from the webos-internals testing feed.
I actually had this issue myself yesterday, in that I couldn't flash anything. What I ended up doing was deleting ALL the partitions, doing a factory reset to 3.0.0, then upgraded to 3.0.5, then reinstalled using ACMEInstaller. There's a guide here on how to reflash back to factory (which removes everything - Android, WebOS, all the partitions and data of everything), which I followed, then I reinstalled the latest nightly (20120402) with ACMEInstaller.
That's what I would suggest. Yes, wipe-everything-and-reinstall is kind of annoying, plus you lose everything from WebOS, but this way you're sure to have it working again, like I did.
Then, as a suggestion, when you flash the ROM, flash JUST the ROM, and the GApps zips first. Boot up and make sure they work. Then flash Rohan's tweak, reboot, make sure it works. Then reboot, do a backup, and flash the other stuff one at a time, so you can try and troubleshoot where the problem lies.
That seemed to work, thank you.
Before I did that I tried repairing the partitions using Tailor, however it didn't work.
