I just purchased a 'used for 1 wk' gtab. It has the stock 3588 rom. The previous owner installed Clockwork mod v 2.5.1.8. I'm wanting to install Vegan 5.1.1. From what I've read CWM v.08 should be used for this which I believe is v2.5.1.1 bekit-.08. Is this correct? and if so how to I go about 'downgrading'? I've looked at the NVFlash threads but not sure if that's the route I'd need to take. I've also seen that other android devices have a 'clockwork rom manager' that allows the selection of CWM versions. Thanks for any help you can give. As you can tell I'm new to this.

The best way to do this is actually do the NVFlash (restore tablet to stock) and then installed CWM (bekit-.08) and then flash a custom rom on it.

I was reading the thread on how to install TNTLite 4.4.0 and it recommends NOT installing CWM. However, from what I read on other threads, it seems like people still do it anyways.
In addition to this, I'm using a Mac and so lsusb and nvflash are not easily available to me.
So, should I still install CWM as a backup just in case anything happens?
Speaking of this, if I go into a bootloop, can't I just install a stock rom on an external sdcard, and then boot up the gtablet in recovery mode to load the stock mod from there? Could this be an alternative to having CWM installed?
[edit]
Oops, I clicked on submit too quickly before I was able to check the box to make this a question. Can a moderator please make this thread a question? thanks in advance!
Actually, TnTLite 4.3 and later come with CWM as part of the "Recovery Pack" which is a toolkit that allows you to toggle between stock and cwm easily. Check the first post in the TnTLite sticky thread.
This has been the most frustrating experience I have ever had with an Android device...
I was one of the lucky few who got one for $280 on Amazon and apparently it had the newest build on it that has the boot loader locked down.
I went through all the stickied guides, warnings about the locked bootloader and NVFlash. Needless to say, I have done my homework.
I tried in vain to install any ROM, but the only one that would install is TnT, which to the dev's credit it was a huge step above the stock ROM, but *shudder* that interface...
Long story, short; I managed to install CWM, fail at any install of a ROM (3 bird screen) and and ended up flashing with NVFlash to 1.0-2638, tried to flash ROM's again and again only to reflash 2638. It has been a LOOOOONG day with this thing.
I am at my wit's end.
Here is what I have 1.0-2638, no CWM and a bottle of Patron Silver...
How do I get a ROM on here...

Thats sucks, and i feel for you. I am also someone that just purchased the gtablet from amazon, and have been reading the forums throughly and it clearly says to downgrade before attempting to load cwm and flashing a given rom. So i guess my question is, did you downgrade before flashing?
@Compusearch... welcome to the G-Tablet world...
before you go ahead... look though the forum and FAQ posts...
do you have a particular ROM in mind??
keep these in mind...
if you install the latest 1.2-4329 ROM, you cannot install a custom kernel... so most custom ROMs like CM will not work... there are three 1.2 based custom ROM available (can't post the links so google Century Eyes or Mountain Laurel)
if you install a Gingerbread ROM like CM7, hardware video decoding will not work...
a start up from where you are... get the 1.1-3588 ROM from http://forum.xda-developers.com/showthread.php?t=842000 and flash it with the stock recovery... it's the best base ROM... then you can flash CWM 0.8 bekit if you want to install a 1.1-based ROM (most ROMs available here) or move to 1.2-4329 and install a 1.2 based custom ROM...
you can easily nvFlash back to the 1.1 based ROM even after you move to a 1.2 based ROM...

Trust me, I went through all the FAQ's and Guides here. I even found a bunch of youtube video's showing how to do the installs of CWM and ROM's. I can follow along, but the end result is always the 3-bird boot screen.
I am seasoned veteran of installing ROM's: Droid, DroidX, Nook (too easy), Galaxy Tab, Captivate, HD2 (winmo7, android), MyTouch3G, and HTC Inspire. I know the procedures and concepts very well.
I think the variable that is screwing me over, is what was initially installed on my gTablet when I got it this week.
I assumed that I had 4349 as there was no available update when I checked for it over wifi. With that in mind, I did downgrade it to 3588 per:
http://forum.xda-developers.com/showthread.php?t=1036956
Even with that, I could not install any ROM's other than TnT Lite.
I am wondering of the latest batches of gTablets are locked down beyond what the newest update 4349+ already does.
Technically as it stands, I have 1.0-2638 installed and that should have the unlocked bootloader and I should be able to follow this guide:
http://forum.xda-developers.com/showthread.php?t=865245
I would assume that logically, if I have an earlier version of the original TnT, that I can install CWM and then any gTablet ROM.
Am I wrong to assume this?
[edit] I want to be able to use the Vegan Beta 5.1.1 ROM
Stupid question but have you actually tried to install a rom after nflashing. The problem you were having before was the partition structure was wrong and nvflash should have fixed that. You can also extract "recovery.img" from bekit 0.8 zip file......
Copy recovery.img to your nvflash directory
Rename part9.img to part9.bak
Rename recovery.img to part9.img
Run nvflash again
This will flash cwm for you. Then try clearing data and flashing anather rom

nvFlashing back to the 1.0 release will definitely downgrade your bootloader... and then I recommend upgrading to the 1.1 branch (3588)... install CWM using the stock recovery or using nvFlash (as @thebadfrog said)...
Format all partitions using CWM... and even try re-partitioning the internal SD card using CWM to 2048MB ext, 0MB swap... and then install a custom ROM

Thanks, Craig and Frog for the tips. This really should be added to the current FAQ.
Sadly, now that I can actually use the tablet, I am HATING the view angles on it.
For a company that prodomiately makes nice monitors and LCD's this is some BS right here.
I know that ViewSonic slapped their name on it, but seriously, who over at VS said that the screen was great and ready for production?
Yeah, the viewing angles aren't great... but it's perfect for a traveller like me... I can sit on the plane and use my tablet without anyone seeing what I'm doing!!
And ignore the dalvik wipe error!!
I wish more people would look at repartitioning as a "step" during the flashing process as apposed to a maybe. All the roms and recovery images are built off of one specific partition set and it is in my book a necessary step to make sure we are all on the same page.
Glad you got it sorted

We have debated that for several months since discovering the different partitioning. The only real way to "brick" for real is through a bad nvflash therefore it makes since to skip that step until necessary.
I think all roms should be nvflashed anyway so you have to understand and be able to use the recovery tools to even modify your tab. But thats my own opinion
Hi,
i just got my G tablet recently and I decided to install Clockworkmod and TNT Lite.I followed instructions to install Clockworkmod using the a USB cable and it worked perfectly.I installed v3.0.2.8.Then, I downloaded TNTLite and moved the update.zip file to the root.When I did that, the only option to put it on the root was to replace the update.zip file from Clockworkmod with the new file from TNTLite.I went ahead and installed TNTLite and installed pefectly.I booted the tablet but it got stucked on the splash page with the Viewsonic logo.I don`t know what I did next but now every time i boot it goes straight into Clockwordmod.I reboot and doesd the same thing.When the splash page appears, in the top left corner it says:booting recovery kernel image.
Can anyone help me?
There are a couple of issues here.
First of all you need to determine which bootloader your gtab is on. There is a sticky which will help you with the whole bootloader issue. You are likely on 1.1, which is incompatible with the version of clockwork you loaded. You need clockwork .08 for the 1.1 bootloader. v3.0.2.8 only works with the 1.2 boot loader.
TNT lite has been retired, and although it is a solid ROM, it isn't being actively developed. The active "version" of TNT lite is hosted on slatedroid and is called Mountain Laurel (almost certain of the name, but I could be mixing them up). Both of those are based on the 1.2 bootloader.
Also TNT lite and Roebeet's other mods are typically installed via standard recovery rather than clockwork mod. This is at Roebeet's recommendation, and should have less rick of brickage.
Goodintention's site http://viewsonic-gtablet-for-dummies.webs.com/ should get you up to speed.
Your best bet at the moment may be a full restore with nvflash, which you can read about on the site above. The site will also help clear up the 1.1 vs 1.2 issues.
Thank you very much for the post!
I will follow your instructions and I will post a message tonite with the results of my experiment
Wish me luck
Good luck. Be careful though, my instructions are only a quick guideline, be sure to stick to gtab for dummies site, or something like of these tutorials:

You really need to go to my site gtab for dummies linked in my signature. There you will find step by step instructions on how to flash (install) a new rom. I hope you used the files provided on my site because the nvflash on my site came with cwm pre-installed. And on my site, you will also find a list of all available roms at this time. Just go there and see for yourself. Make sure you use the "start here" page.
If your on stock 3588 then this tutorial is a great reference guide:
http://forum.xda-developers.com/showthread.php?t=865245
As for installing a ROM it's pretty straightforward and it doesn't sound like you'll have much trouble. Vegan Froyo and Vegan Gingerbread are great solid roms. There's a lot to try out so have fun.
Thank you very much for your help! I will work on this tomorrow and post the results!
Really appreciate your help! Thanks!

Just to add my two cents - it looks like you are mixing up 1.1 / 1.2 dev branch items (luckily you didn't soft-brick!).
TNT Lite is a 1.1 ROM (no longer being developed), but my 3.0.2.8 rev5 cwm is for the 1.2 bootloader, so they aren't compatible. Perhaps you used another 3.0.2.8 that's not mine?
"Mountain Laurel", over in Slatedroid, is he successor to TNT Lite. It's based off stock 4349, and it's 1.2 dev branch based.
As for the cwm reboot issue, did you try and wipe data in the UI, with cwm installed? If so, the "cwm forever reboot" is known to happen. The "fix" is to get standard recovery installed so that way the data wipe completes.

I too am stuck in CWM. I was on the 1.2 ROM branch, and was using the CWM v3.0.2.8 (1.2 branch). How did you get out of CWM? I'm guessing you had to do a nvflash - I've done that before, but how do you get to the APX screen? (if that's what you did).
Roebeet also said "As for the cwm reboot issue, did you try and wipe data in the UI, with cwm installed? If so, the "cwm forever reboot" is known to happen. The "fix" is to get standard recovery installed so that way the data wipe completes."
1) yes I did a wipe data using CWM but not sure what Roebeet meant by "UI (user interface), with cwm installed" - I'm not sure how else I could do a CWM data wipe using the UI?
Edit: got it. In the UI, sometimes under Security, you can do a factory/data wipe from there.
2) The "fix" " is to get standard recovery installed - what is the "standard recovery"? and more importantly, how do I install it?
Edit: Is the standard recovery - going back to the gtab stock (depending on what branch you are on)?
I am currently running:
TNT Lite v4.4.0
Kernel version 2.6.32.9-00001-g6e47897-dirty
[email protected] #221
Build FRF91
I updated from stock to this using clockworkmod a few months ago. I was looking to install the latest version of Vegan from CW but it did not work. Did some searching earlier this evening and found out I had to update clockwork mod. Searched for about 2 hours and could find ZERO instructions on how to update from clockwork mod 2.5.1.8 to new CWmod v8. Finally came across a post that mentioned using an app called ROM Manager which would do it automatically, so I said cool and went for it.
Now I can't access CWmod at all
I hate to ask a newbie question but I can luckily still boot into TNT, but no clockworkmod. What do I need to do in what order so that CW can work again and then I can move on to VEgan (I'm looking for a more stable ROM and as told that would be a good bet) Thank you to anyone who could lend a hand. Been at it trying to read and fix on my own for a few hours now. I even tried looking at this site but again, do not know what to do in what order to fix (http://viewsonic-gtablet-for-dummies.webs.com/rom.htm)
I hope this all made sense. Take care.
Oh, also, when I searched here I found this http://forum.xda-developers.com/showthread.php?t=1023164
but did not find it applied completely to me. Thanks again.
There may be simpler ways to solve your problem, but at the very least you can nvflash back to stock with clockworkmod 0.8 pre-installed. See this page:
http://viewsonic-gtablet-for-dummies.webs.com/nvflash.htm. Go down to the section entitled 'NVFlash to Stock with CWM pre-installed'.
From there, you shouldn't have any problem getting Vegan Ginger Edition installed, or any other ROM for that matter.
Ladies and gentlemen,
I'm getting my viewsonic g tab tomorrow and have been reading the threads about nvflashing bootloaders. My question is (if my tablet comes with bl1.1) can I just nvflash from bl1.1 to bl1.2? I ask this because it seems some of the folks here either don't want to upgrade their bootloaders to 1.2 because theyre either too scared of bricking or "like" (?) bl1.1 but I like the rom branch and veriety of the 1.2 bootloaders. Thanks in advance folks.
BTW, I have read the guide on nvflashing (very great write up and summary of nvflashing the g tab) and it covers everything except if you can nvflash back and forth between the 2 bootloaders. This is my first tablet and please excuse my noobness on the subject of nvflashing. I know most topics regarding cwm and how to use it and have owned, rooted and flashed MANY ROMs on a total of 4 android phones. Thanks again.
You should be just fine to nvflash to 1.2. Many consider it "safer" to flash to the stock 1.1 TnT first but if your tablet comes with 1.1 you will already be there. Once you are on 1.2, you probably will not want to go back, but it is possible.
However, if your tablet comes with 1.1 you could also just take the OTA update to get to 1.2 and not have to nvflash. Then you can install CWM and a rom. Check out this site for lots of good info if you decide to use nvflash, and also make sure you read this thread. Backup your .bct file and use it any time you use nvflash. Some roms will require you to nvflash to change the size of the system partition (ICS for example).
Also, be sure to use the correct version of CWM:
CWM v08 - use for bootloader 1.1 only
3028 rev.5 - use for bootloader 1.2 only
5504 touch - use for ICS rom only (is included in the nvflash file found in the ICS thread)
BTW - if you do take the OTA update to get to 1.2 make sure you have the stock recovery installed NOT CWM.
OK, so my understanding here is; tab comes with 1.1-update to 1.2 with ota (no cwm, install after update)--> tab comes 1.2-downgrade with tnt 1.1 tool then nvflash back to 1.2 w/cwm? Hope that sums it up. And my whole point here is to end up with 1.2 w/cwm so I can start flashing bl1.2 branch ROMs. I think I'm pretty sure what I'm doing now. Thanks bud.
Yep, except that if the gtablet comes w/ 1.2 already there is no need to downgrade, and you only need to nvflash if you are going to use a rom that requires it. Just install CWM and then your rom of choice.
Thank you again daggerdave. My g tab didn't show up today. Tracking says tomorrow. Excited to have my first tablet!!!!
