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....)

To begin with, I am a complete noob with any and all phone mods. I'll run down what I've done and whats happening when I do it.
I used the adb method to root my tbolt. Once that was done, I installed Superuser, and Rom Manager and flashed with the latest CWR, after clearing the download manager and turning on the erase option in settings. I have done this (flash cwr) before each attempt to flash a rom.
I have tried 3 roms: Das Bamf 1.3.2 themed (tried twice), The Perfect Storm 1.2 and VirusROM RC1b3. I used identical steps to flash them:
1. Booted to CWR
2. made a nandroid backup
3. wiped data
4. wiped cache
5. wiped Davlik (sp?)
6. wiped battery
7. install zip from sd, choose zip from sd
8. after installation, reboot
When I reboot, the white boot screen with green htc logo appears, disappears, appears, disappears, and so on. I assume this is what people are referring to as a boot loop. It happened with both Roms, and luckily I am still able to get back to recovery and restore the stock rooted rom.
I've asked for help in the android forums, and a couple of people there have been trying to help, but the only real suggestion I've received is bad dl's. I haven't been able to find the md5's for the .zips to compare to what I generate, but I can't believe 3 straight dl's are corrupt.
Anyone have any suggestions as to what I'm doing wrong? Any help is greatly appreciated.

Did you try hitting install ROM from SD card in ROM manager and just flashing it through the app? Not sure that will change your result but it flashes it for you and you can choose the options to make a backup and wipe. Can't hurt to try it.
I did try it with Das Bamf, but got the same result. Thats when I read that using rom manager to install the roms could cause problems and started doing it manually.
After uninstalling/reinstalling rom manager and flashing cwr again, I got TPS 1.1 to flash, and its working great. I then tried to flash 1.2 thru cwr, both with a data wipe and without, but both times it boot looped.
I've dl'd TPS 1.2 from a different source, and I'll try to install it when I get home. But any other suggestions are very appreciated. I'm just glad I finally got something to flash.
I'm stumped. I tried new dl's of TPS 1.2 and Das Bamf 1.3.2te, and both of them failed. I even tried turning off my antivirus while dl'ing and moving the file to my sdcard, but it didn't make a difference.
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
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.

i'm having a hard time myself...i nvflash and boot to stock Vegan RC1, or CM Harmony Stable 7.0.3, very well...but when i load pershoot's latest kernel, it falls apart, and i get wifi error!
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!!
Hi,
Currently using latest firmware KI3 with root.
I'm able to use CWM, backup, install zips, everything.
However, if i install a ROM trough a ZIP, i get a boot loop.
Only way to get back the phone, it's to install via ODIN with latest KI3.
Even tried with Litening Rom, and got the boot loop.
Any ideas ?
I was very keen to return to CM7.
Tx in advance.
Did you exactly what's mentioned here?
Install via ClockworkMod (do not use ROMManager for initial install):
Make sure you're running a rooted device.
Root your device and install ClockworkMod Recovery (http://forum.xda-developers.com/show....php?t=1118693)
Do a Nandroid backup!
WIPE (wipe data/factory reset + wipe cache partition) - do it for real.
Install the ROM from internal sdcard using ClockworkMod Recovery.
Do not reboot! We mean it - do nothing except choose zip and continue next step (if you come back to us with permission issues in install, we will know you did not read the directions and will call you an idiot). If it just plain hangs, reboot directly back into ClockworkMod recovery and continue at the next step.
Install the ROM from internal sdcard using ClockworkMod Recovery, again (due to a bug in the install).
Reboot
Install the Google Addon through ROMManager which is easiest, but you can
download the gapps.zip and install via ClockworkMod recovery instead.

Did you try flashing a old stock ROM like KH3, root it then try from this base?
I went from Villain ROM 2.3.5 to CyanogenMOD without any problems.
It's essential that you flash CyanogenMOD !TWICE! in a row when you're coming from a stock ROM.
Thanks.
Gonna check, as soon as i'm @ 127.0.0.1
Same behaviour, back to boot loop.
Tanx anyway!
I had a similar problem so here goes my help.
Cf root kernel uses a modified version of CWM that isn't compatible with CM7 or something like that. So what I did was flash this kernel http://forum.xda-developers.com/showthread.php?t=1118693. Get the kernel with CWM 5.x.y.z With that I got a compatible version of CWM and from there I flashed CM7. It is important that you do a full wipe, wipe cache, wipe dalvik cache, format \system, everything so you don't get any trouble. THen you flash the CM7 zip file, when tha t is done, flash the zip again for a second time (don't reboot just do it after the first flash). After that reboot. That worked for me at least.
A tip: If you can't reboot your phone and you have no ROM zip file to flash via CWM you can mount usb storage from CWM for putting the ROM in sd card and flash with CWM. That way you don't have to use ODIN to recover.
Tanx Tomas.
Tried with CWM 5.x.y.z and upon "WIPE" always got an error for mounting partitions.
Could't mount CACHE, SDCARD .....
Tx anyway.
Back to ODIN, back to stock 2.3.5
PS : I have to get a JIG to reset ...
Currently stuck in bootloop and would like to return back to stock rom.
These are the steps I've taken:
1) NVFlash full restore using bekit's original image
2) Bootloader update (1.1 to 1.2) with CWM
3) installed gtabcombover 3.4.2, slow response rom
4) formatted sdcard to 2048/0
5) Ran TeamDRH 350 Prep to install TeamDRH ICS
6) Installed TeamDRH-ICS-Beta-1.3 (included TeamDRH recovery)
7) Software was unstable so I went through step 2 again.
8) Boot loop at Tap n Tap splash
9) Ran bekit's NVFlash, still stuck at bootloop.
Are there any links that I can be guided to that will help correct this?
Will need to look at logs to find out precisely why you're stuck in a boot loop, but, try one of these to wipe all data (except ROM) on the tablet. That usually fixes boot-looping.
1. If you have CWM recovery, then a) format cache and b) repartition the internal SD card.
2. If you have stock recovery, then see this thread.
Did you delete dalvik and do a factory reset? I would try that.

An FYI: A factory reset in recovery mode, and in the ROM (when it works!), will clear the dalvik cache.
And, a factory reset is functionally what's being done in both steps in my post #2.

Don't need all those steps--only step 4. is needed here. In this case, the user's problems are most likely caused by not repartitioning the SD card/wiping cache between installing different ROMs.
