G-Tab with TabnTab
Right out of the box... it would not boot. The Viewsonic splash came up... then the "G" Tab splash... then screen went dark. Pressed the Power button to turn it off - and after 3 attempts to start, I got the TabnTab splash and the thing started. After running battery down, turned it off and when tried to boot... same thing -- only worse. After dozens of tries, nada. Finally did the Power + and On/Off and reset to factory. Did this a couple of times during the day as the problem reoccurred.
It's finally running somewhat... keeps going into some deep sleep mode that requires a reboot -- and then more of the same... the latest attempt how has the TabnTab splash up... but it is "running" a LONG time.
I left a message at the dump tech support number -- after some lady answered w/o even saying a company name. I'm not holding my breath for a return call.
I'm a complete newbie... but has a slight background with other OS'... so if there is something relatively "safe" to fix this... send your suggestions.
I do have a 8GB SD card in the machine.
Thanks in advance for any help...
Follow this link to all the info you need to install a new os or just install cwm to clear cash and factory reset.

Simple easy to follow instructions.
Good luck
Boot Problem
Mine does the same with build 4349, and has done it since 4349 was released.
I talked to "Ken" at G-TABLET Support, and he said my tablet just needed to be re flashed in a way that only the "factory" can do it. He issued me and RMA and I am sending him the unit tomorrow.
I you want more info Email me at [email protected]
You might also want to try an SD repartition (but you'll need the 1.2 version of clockworkmod for that) - the gtab for dummies site has the link.
You could RMA it and get something just as bad, so I wouldn't do that quite just yet. Usually we try things in this order, before we give up completely:
- Wipe data (which you already did)
- Re-flash the ROM. For 4349, there are ways to do that, as well as older stock ROMs.
- SD repartition, via clockworkmod. This actually solves a LOT of issues, so I would definitely attempt it.
- Re-flash with nvflash (the last ditch effort).

Probably either an SD repartition or nvflash is my guess.
Good luck!
Going RMA route
Well, I did everything but the ROM and Kernel mods... and it worked for a few hours.... but after turning it "off," it went back to not booting completely.
I finally got a response from the 3rd-party support company ("Ken" -- who signed his email "Joe" -- go figure....) and he promptly issued a RMA when I told him... "It wouldn't even boot right out of the box...)
Kind of funny... U.S. Merchants is in freaking Beverly Hills, CA! "Biz must be good!"
I came home from work this morning and my wife said my daughter was reading a book and she turned the page and it just locked up. Now when I boot it up it will go to the lock screen, but when I try to slide it to the right it will not do anything, even the clock is at the top left like it should be. Usually you can see the wallpaper on the lockscreen, but now it is just a black screen............
The only thing I can do on the lock screen is just power it off, even then, I have to hold the power button down a couple of times before it will boot up again then it just goes through the normal boot up until it gets to the lock screen and then its stuck again. What can I do to fix this? If I do a factory reset will I have to root it again?
i honestly dont know but a suggestion i see a lot is to do the hard reset which is pressing the n button along with the power button and you have to do it 8 times ill try to find a vid
If you do full factory reset you will loose root.
but the good thing is that its very easy to root
Yeah, I was afraid I would loose everything. I may wait a bit and see if this has happened to someone else before I do anything. If not, I guess I will go ahead and do a reset. I really hate to do that!
have you tried plugging the NT into your computer via the USB cable? I wonder if that would allow you more access?
I would do a factory reset and re-root if necessary. Worst thing that could happen is that you'd have to restore back to 1.4.0 before re-root.
Well I did a factory restore, made sure I was at 1.4.0 and I was, set up everything and connected to the wifi.......downloaded tgps then turned off my wifi. Went through turning on debugging...got that. Started zergy and it noticed my nook since my drivers were already installed. It recognized my nook number and asked if I wanted to root, I entered Y then hit enter. It then restarted my nook and did nothing. My tablet came up with a warning that said I may now move items from my PC to my tablet, please eject nook from computer to avoid file transfer problems. I restarted zergy and it said that my nook is already rooted???? It did not install gapps, launchers or anything.......
I did another factory reset and went through the process again and it did the same thing. I know Im missing something but I dont know what it is. This has happened to me 2 times, once I had to go back and get rid of the update proceedure and reroot and now this. Very frustrating to say the least.
I thought that doing a reset would unroot my nook??? I am wondering if now I have to unroot it and then go back and root it again?

There is more than one recovery process. The nook+power button seems to do a factory reset (reformat and restore /data). The 8 bad boots does a full factory software reinstall (reformat and restore /system and /data).
yea the 8times thing is what i was referring to
*How to make a hard reset - This reset the /system folder to factory (removing gApps, restoring bloatware, removing root, etc)
*How to make a factory data reset (Wipe Data/erase-deregister): Go to Settings> Device Info> Erase and Deregister Device - This will clean/format /data (All your installed apps will be gone)

did you eject your nook when the warning was up?
Yes, I ejected it from the pc. When I plug it back to the pc it gives me the same message.......
At this point, could I just do the one step unroot and then go back and root it again? I will not be able to do anything else to the tablet until Friday because of my work shedule, so I am gathering information until then. Thanks.
Also I was wondering if anyone else has seen this message pop up? I'm almost tempted to mess around with it to see if I can get apk files to install while using the Barnes and Nobel software since it says its rooted, lol. Then again, I don't have the 999 version to block OTAS either.
I received a G Tablet which had been used for development work for a few months. The person giving it to me (not the dev who has left) said the tablet was working fine, but had just become frozen at a reboot after he had tried to erase personal data from the tablet. I asked him if he had erased the sd card and he said "maybe" but that he couldn't remember. I powered the tablet on and sure enough it displayed two lines on a black background, one of which said something like loading kernel.
Now, these tablets were all rooted, and had Android 2.3 on them, via one of the ROMs discussed here. I don't know which one however.
So, I tried using NVflash to flash the tablet back to a stock ROM. Tablet then got stuck in a boot loop; I would see the Viewsonic logo, then the G Tablet logo, and then this would go on forever.
So I shut it down and tried again. This time Nvflash failed almost at the last step after having written most of the image.
And so here I am now, with a totally dead tablet. I cannot power it on. No combination of power or volume up/down buttons work. The only sign of life is when I plug it into its charger, and see the charging light come on.
I confirmed again with the person who gave me the tablet that the device was working just fine before it froze at a reboot after his erasing attempts.
Is there a way out of this? I hope so. Please help!
Thanks very much

I would try popping it open and unplugging the internal battery then plugging it back in. Also hit the internal reset button while you're in there. It's pretty hard to actually kill one of these tablets. PM me if you need any other help.

Started my own thread, didnt mean to hijack. =)
Thanks, I will try removing the battery and let you know.
As for NVflash, I believe the latest version is here:
http://www.slatedroid.com/topic/171...-using-either-11-or-12-based-images-g-tablet/
However in my case I have no idea whether I have 1.1 or 1.2 and there is no way to determine this. Which one should I choose?
Paul
Doesn't matter for NVFlash, just download all of the flash files again because it might be that you have a bad download. Also make sure you have the right drivers installed since the drivers that automatically install when you plug it in sometimes don't work.
I'm pretty sure that if it boots past the birds, the hardware is working okay, so you should run the FORMAT version for NVFlash and then I'd run just a CWM flash setup and see if you can get into CWM and delete the partitions from within that.
The best thing to flash as far as ROMs would be Bekit's 1105 which is stock OTB with a few key changes. If you can't get the 1105 to play nice, you might really have some hardware problems.
I would go with the 1.2 BL, it will give you access to the newer roms as it appears that dev for the 1.1 BL seems to be dwindeling. I upgraded mine to 1.2 the other day and it worked great.
I have gotten a g tab from my father in law after he tried to fix it and ended up buying a new one saying "if u can fix it you can have it" I have tried for hours and days to fix it on my own and have now tried to reach out for help
Basic problem:
-When I got the device it would boot to birds and go to g-tablet screen and no further
-Found viewsonic gtablet for dummies tried nearly everything (i believe correctly)
-Called G Tablet Support and got the "send it in to us and we can add the correct software for $60 if there is no problems otherwise the $$ may go up"
-went back to trying to fix on my own
-failed
Basic info:
-able to NVFlash with 0 errors on any packet
-can boot to g-tablet screen but no further
-can boot power & Vol+/vol- no issue
-cannot partition
-cannot wipe data/ factory reset
-can install zip from SD
Help! any ideas are worth a shot when it means (possibly) a free tablet. Eager to fix and try most ideas to get this thing fixed!
Also, This seemed to me a repost but i have looked at, tried, and failed to fix with several different posts/ideas from this site
I've seen a number of posts suggesting that you power off, open the back, pull the battery, wait a few minutes, plug the battery back in and turn it back on. It seemed to work for a number of people.
There is also a reset switch under the back cover.
I honestly don't know if one of these will work, but it's worth a try.
Can't suggest which rom you might try, since there's no way to tell which bootloader you have (v1.1 or 1.2).
I'll have to try pulling the battery plug tomorrow I don't have small enough tools. But I do know that im running 1.2 got that much outta tech support before they went grabbing for mytwallet lol
Here's a thread that explains how to open the GTab. http://forum.xda-developers.com/showthread.php?t=994881
If you are on 1.2 (and are absolutely sure) you might want to start with http://forum.xda-developers.com/showthread.php?t=1525424 to get the latest recovery ClockWork. Do this after you "pull the plug".
If it doesn't work after that, come back and let me know and I'll try to do some more troubleshooting with you. Since you said you actually had NVFlash working before, this might actually get you up and running on the latest stock rom. From there, you can move up to just about anything you want, upto and including Ice Cream Sandwich (ICS). Just remember to check the forum information about what does not work. For example, if you move up to Gingerbread (3.x) or greater, there is a pretty good chance that you won't have camera or mic support at this time. Some roms don't support hardware acceleration at this point, but many do.
Anyway, come back and let me know how it went.
Awesome thanks. I'll be getting into that soon (after I finish cleaning) just wanted to thank you for your interest in helping me
Hey! finally got around to it but pulled the plug and grabbed that cwm recovery u had linked but i'm still hangin on the g-tablet screen. any other ideas?
I'm guessing that the tech support for GTab was wrong and you actually have a 1.1 boot loader.
Try following the thread here http://forum.xda-developers.com/showthread.php?t=974422 on formatting the gtablet and starting over from scratch.

what 1.1 should i use?

There is no reason to go out of the way to figure out what Bootloader you have. the NVflash files that you found on the ViewSonic Gtablet for Dummies guide will be your best bet. If you can get grab the NVflash files that include CWM recovery those are the ones you need. After NVflash is complete and you see the Gtablet splash screen press and hold the power button till the tablet shuts down. Once shut down you need to reboot into recovery by pressing down the volume + and press the power button to boot up. That should get you into CWM where you need to do a wipe data fatory reset, wipe cache and also wipe dalvic cache under the advance menu. Once that is complete then you need to back out to the main menu in CWM and reboot. Make sure that you do not select Reboot Recovery. Give the device some time and it should boot into the Stock TapUI where you can mess around with it from there.
I would choose 1.2 build 4349 w/CWM preinstalled (Old) NVflash file found here http://viewsonic-gtablet-for-dummie...65610&fw_sig_premium=0&fb_sig_network=fw#2310
Many times in the past the wipe data/ factory reset and wipe dalvik and most anybody those options lock up the tablet. It will just hang on the screen (depending on the option chosen) and not move from there for hours on end... Thoughts on why? Hoping not a hard drive problem

You will need to get your partitioning working. You can boot into recovery? And what happens when you attempt to partition.
If you are able to go past the 3 birds splash screen and see the gtablet screen, then you're on the stock ROM and the problem is most likely with the partitions on the internal SD card (or the card itself). In which case, nvflash will not help you.
Set up ADB and then run these 2 commands and post the output after you've tried one of those operations you mentioned in your 1st post:
Code:
C:\SOME\PATH> [B]adb shell dmesg > dmesg.txt[/B]
C:\SOME|PATH> [B]adb pull /tmp/recovery.log[/B]
I am pretty sure I know the answer but want to make sure its true as its a costly issue: I did some searching and found a lot of threads with different options over the last few years, so just want to confirm; I have:
Asus Transformer Prime TF201, unlocked with latest ICS official (WW) installed via SD Card
I was intending on giving the tablet away to a family member, so decided to factory reset the device. I went to the PWR+VOL Down menu, and selected wipe which I read was the way to perform a factor reset. After a long time of this process, the tablet powered off (was plugged into mains with full batteries). I powered on by pressing PWR button some time later. Now the tablet just boots onto the screen that states "The device is UnLocked" in the top left, ASUS in the middle (and some lies about perfection), and the bottom right "Powered by Nvidia TEGRA".
If I power on:
1. PWR + VOL Down, nothing happens, it boots to the same screen, no menu
2. PWS + VOL UP, the screen is black, the tablet vibrates and if i have it plugged into a PC it detects it in APX mode.
I've tried a full power cycle, and read about the nvflash tool. I unfortunately have no nvflash backups, I'm not sure that tool was around when I unlocked the tablet, and as i'd not been flashing any custom roms (although I had intended) I'd not seen that tool before.
As I understand the state of affairs is:
1. Somehow the bootloader is jiggered, i guess the wipe didn't work right
2. APX is useless if you don't have some backups created with a tool
3. The only current solution is to send it to ASUS and pay almost exactly the same price as a new tablet costs
Is there any other options I can do with an unlocked tablet and only access to APX?
Any likelihood that there is anything that can be done with nvflash in the future without needing a custom backup that is unique per tablet?
I have exactly the same problem please someone help us :angel:

Bricked TF201 - Stuck in bootscreen
I have the exact same problem. :crying:
Please, I know that there are many brilliant minds in this forum, help us n00bs get out of this mess and lead us into the light. Oh, and bump this thread
I hate to be the bearer of bad news, but I hate hit and run thread posters so I will provide an update.
I am afraid that my tablet was bricked. No way back from that state after reading the entire internet. I have purchased a replacement motherboard, popped open the case and replaced this. After replacing the motherboard, I now have a working tablet. I wish someone would have documented the NVFlash process requirements previously, but that's the risk of following guides on android sites I guess.
So to summarise the initial post, if you are in that state, at current and likely forever, you are hardbricked and the tablet can not be recovered in that states without a previous backup. The only way for it to be repaired is to send it to Asus who have a database of firmware, etc. and will charge you for repairs (~200€), or to go on ebay and purchase this motherboard:
0K0AMBA000
This will cost you ~80€ + shipping, and you must be comfortable working with electronics. Its mostly very clear when you pop off the case, everything has its place. You will need some plastic case pries and a small screw driver.

This sucks, I did the same exact thing last night factory resetting it to give it to my brother. I still don't understand what exactly I did wrong as I've factory reset this thing before. I had CM on it before but have been using the stock rooted ROM & recovery for the past 6+ months.
bricked?
I've been scouring that internet and haven't been able to find a case exactly like mine, but most are similar. From what I can remember (it's been months since I initially 'bricked' it), I was upgrading a cm nightly and did the data/cache/dalvik wipe like the instructions said and I became stuck in a bootloop after leaving recovery. When I tried volume-down and power, I was left with the original 3 options and after some reboots and shutdowns I ended up doing a factory data wipe. From there, when I rebooted the phone I was left with just 'Wipe Data' and 'Fastboot.' Wipe data does nothing more and when I choose fastboot I am left a message 'Starting fastboot usb download protocol' which never changes.
I have tried to push TWRP onto the device but I can't get into recovery (unless I'm doing something wrong of course). Sorry if I missed a duplicate of my post somewhere on here, but if so can someone at least point me in the right direction? Thanks!

try another ROM
This has worked for me everytime, possibly due to dud bootloader install or some other thing: so long as I was able to recover to CWM with pwr+vol down, I installed virtuous prime rom. This rom was on sdcard already, not sure if you can get from adb if machine in this state. Anyhow, this virtuous prime rom replaced the booting sequence, restored OS and machine worked again.
Asus TF201 stuck on Asus Logo
My Asus Tablet was slow while browsing, and it had JB 4.1.1 with stock rom, so i tried to unlock the device, which was successful and was planning to push the CM11 Kit Kat. I booted in to recovery mode as i could see the 4 icons and then tried to do wipe data/factory reset and then it rebooted and got stuck on the asus logo and at the right bottow with the message powered by NVIDIA Tegra. I tried all the options to get into recovery and also downloaded drivers on my laptop for APX, but no luck at all. What are my options or if any one was successful to get it fixed. Appreciate any help here from smart guys out there. Thanks
