Help...Won't Power On After Boot Looping - G Tablet Q&A, Help & Troubleshooting

Hi,
My device started boot looping while trying to restore to stock ROM to update to a new ROM.
I wen't through the nvflash process successfully (meaning nvflash wrote the images to the device) but it continue with the loop.
Eventually, it powered down and now it will not power up at all. Battery is fully charged.
Any ideas?
Thanks.

OK, so I figured out that the device was stuck in APX mode.
nvflash doesn't seem to be fixing the problem, so I'm trying adb. It doesn't seem to see the device at all. I'm sure I'm missing step on how to work with adb.
Can anyone point me in the right direction for getting adb connected properly?
Thanks.

I'm trying to get adb working following this guide:
http://forum.xda-developers.com/showthread.php?t=902860
but it cannot see the device. The drive is installed fine but the device does not show up.
I know that if I can get into the device I can put it in debug mode, but I'm not sure how to do this now. I'm thinking this could be my problem, that the device is not in the correct "mode"
Any ideas?
Thanks.

did you get this resolved? i'm having the same problem.

I've been able to do that a couple of times, but after nvflash completes, just get into a TapNTap logo loop and eventually just powers down. When I am able to turn it back on, it goes straight into APX mode.

Do you mean to install CW from external micro SD?
Thanks.

This is Where I Stand
1. nvflash from TNT lite post
2. Completes and reboots, goes into GTab screen, no Viewsonic screen
3. TapNTap screen and then to n animation
4. Reboot and go to #3. Haven't counted but at some point it just powers off.
I have tried installing CW from the external SD card but cannot get to it.
Have tried adb but cannot get it to connect.
I'm totally out of ideas...I'm thinking that if I just let it sit there, it'll just work

Finally Worked
I have no idea what made it work.
I decided to just take a break and left the tablet connected to the computer through USB but powered down. Came back a couple of hours later and when I turned it back on, I got the Viewsonic screen.
After that, I was able to reboot and go into CW and do a factory reset, which put it in a really old version. It was all easy from there.

pgonza02:
As I understand, you can now power off and reboot you GTab.
Can you recall what were your steps to get to this point?
I'm stuck in APX mode for almost a month! I don't know what else to try...
Thanks in advance.

I tried many things, including:
Install CW by replacing the image for partition 9 with the update.zip for CW (basically rename update.zip to whatever the img file is called)
Add CW to external SD card and attempt to reboot.
Eventually I just left the tablet alone and when I came back I turned it on I saw the Viewsonic birds (this seemed to be the key, when it was not working I never saw it)
I read a thread somewhere that mentioned that nvflash has the ability to redirect output through the HDMI out so you would not see it in the main screen. My guess is that what's happening is that the output of something, that is taking time to complete, is going out that way and I just could not see it. By leaving it alone, whatever it was, completed. This is just a guess, maybe someone with more knowledge can confirm.
Sorry I couldn't give you more details.

Boot loop and black screen
I'm having the same problem. In fact, I'm unable to boot into APX mode.
I have the cover off and read about a hardware reset button. I tried pushing the
reset button (k2) but nothing happened. I also read that I can disconnect
the batter. But, I don't see where the battery wire can be just disconnected
without soldering.
Any ideas?

[Q] Bricked G-Tab?

Could I have bricked my tablet? Or could there be a way to recover?
As for what it's current state is; (I am sure is is stuck in the reboot loop) When powering on the tablet, it displays "Android", goes dark, and repeats. Though this is a change from when I was trying to fix it on my own. Before it looping, it would show the "Android" screen and just sit there.
No comes what I think the REAL issue is... Running 'ClockworkMod v2.5.1.1-bekit-0.8', I am unable to mount an external SDcard or mount the USB Storage(text in menu implies to me it is the USB cable to computer).
So other than the images already on the tablet, I seem to be unable to get a new image into it. And of course the images on it don't do any good.

Most definitely not bricked. I've recovered from a much worse situation (bootloader wouldn't even budge - couldn't boot into recovery or regular at all).
Since you are able to boot into recovery, there's probably a way to get things working without resorting to nvflash (we'll get to that in a second - nvflash is the failsafe mechanism, and you should be able to re-nvflash your tablet back to its original state if all else fails).
Here's roughly what I'd try in order:
Option 1) Figure out why you are unable to mount as USB in recovery. I've actually never heard of this problem. Are you using the right cable - i.e. a working USB-to-mini-USB cable (I don't think this works at all with the full sized USB port under the latch cover). Have you tried it with another computer - perhaps there's a driver issue on your PC?
Option 2) If for some reason you really aren't able to get USB mounting working in recovery (I'm skeptical - again, I've never heard of that problem - unless you really did flash a bum recovery image or something - but seems unlikely), then I'd see if you can get ADB working properly when you are in recovery mode. Search around and read about setting up ADB if you haven't already - just a matter of getting the right driver installed on your PC and installing the binary stuff (either from the full Android SDK or one of the packages that just has the ADB stuff floating around). Search the forums, you'll find some references to help you get this working and download the right stuff.
If ADB works, you can always use "adb push filetoflash.zip /sdcard/filetoflash.zip" to put a new file on your internal SD card area and flash it.
Option 3) You can always use nvflash. I'm not going to write up a tutorial on it here - search the forums for nvflash, there are several HOWTOs. Look for the stuff Roebeet posted. You'll need to install the APX driver on your PC first before this will work, and Roebeet's posts don't explain how to install it on Windows, so you'll need to search separately for that. I have gotten this to work before, but it's a pain and I only recommend it if your recovery image is truly trashed or your bootloader is malfunctioning as mine was. In other words, don't bother until you've exhausted the first two options.
So in short - you are in a pain-in-the-ass situation, but you have by no means bricked your tablet - it is very, very far from bricked. Give us more info on *exactly* what happens when you try to "mount as USB" while you have your mini USB cable plugged into the G Tablet - do you see a drive appear on your PC? Are you running a Windows box? Mac? Linux? Have you verified that a USB keychain drive works fine with your PC but the G Tablet won't mount? Basically we need some more info to guide you in your search.
Ok finally had some free time from cleaning/packing and house hunting to try fixing the tablet.
Good news is that I was able to mount the USB. I didn't notice the cat nibble on my cable... So once I dug a spare out, I was able to copy a TnT-Lite image (still had on computer) onto it right quick. Restarted and it installed the image.
So now it has TnT-Lite, though it is weirdly stuck on the setup wizard. It tells me to touch the android to continue and shows an animation of a hand touching the android. But when I touch the android, it turns white and thats it. Also I can change the language to UK or American English. Plus when I press the menu button, I can go to wireless settings, as in cell phone wireless settings. Lastly, I can make an emergency call. So new worthless image. YEY!
I next tried to reboot back into ClockworkMod to see what I could possibly do to get by the lack of continuation in the TnT. But the image install did something interesting. When trying to enter Clockwork Mod, here is what it does from powerup: Displays "Detect a recovery key pressed" then on the next line "Booting recovery kernel image", blanks the screen and then displays "Android" for a few seconds, lastly switching to an exclamation mark in a triangle and rebooting.
So how do I go about screwing it up more?

It almost sounds like you now have stock recovery in your Gtab.
If that's the case, then maybe copy a stock TNT update.zip onto the external Sdcard, and create recovery/command file on there with the string for SDCARD2, then reboot w power and volume+. If you do have stock recovery, that should flash it back to stick TNT. Try Stock TNT 3452, since that'll also flash a stock recovery for sure.

Looks like Brian and I crossposted each other .
For the recovery/command file on the external SDCARD, put the following text in it:

No really, I've Bricked It
So, G Tablet arrived about 5 hours ago. I got it rooted and tried to install CMod 8.1. Things went wrong but I'm not sure what. Anyway, the last thing that I did was to boot in Recovery and then I selected, Format System. Now, when the tablet is turned on, in the top right corner, I have a tiny red message, Magic Value Mismatch. I get this message whether the SD card is installed or not.
I know this information is a little vague but as a Nod, it's all that I have.

I'm freaking out, I think I bricked it...
I'm only getting the black android screen, I can't seem to mount USB, suggestions?
Ive been stuck right where you are a few times, not to big of a deal, just NVFlash back and start over. I am assuming you are getting the black screen you mention is the APX mode one you get by starting your tab by pressing vol down and power at the same time.

Tablet will not turn on

I followed this guide http://forum.xda-developers.com/showthread.php?t=861950 (Roebeet's post) which brought me back to stock.
However, when I apply the 1.1-3588 the tablet shuts off and is unable to be turned back on. The only way to turn it back on is to run the nvflash_gtablet batch file. At which point a receive a notice saying 'The update to version 1.1-3588' was not successful. Please try again or contact customer support.'
Why is the tablet unresponsive after the failed update? Why must I NVFlash to reactivate the screen?
I searched through the forums for the past hour and although I found similar problems I have yet to run into my exact one. I am hoping to find some help.
Edit*
I have the same problem as another user which can be found here http://forum.xda-developers.com/showthread.php?t=903684
I can NVFlash the stock image (or even the NVFlash of TnT-lite 1.02) and the tablet will boot after the flash and function. Power it off (or do something that requires a reboot) and the tablet will no longer function. No power on (that I can tell), can't boot to recovery......and if I plug the tablet in to the PC I can NVFlash it and it boots. It's like it's stuck in APX mode now. I just have to plug it in to the PC, no Power + Volume- combo.....just plug the USB in and run NVFlash. It boots (to whatever I flashed) and will run until I power it off or try to reboot.
Getting APX mode to function is not a problem......so I can NVFlash it but what I've tried so far has not worked (it doesn't delete the data partition, etc..as I reflash and it's right where it was before I turned it off).

The fix posted by acidburn89 was unsuccessful for me
Citi,
I'm not sure exactly what you are doing, but if you are getting the message
you described, that sounds more like you are booting in recovery or a regular
boot and not APX (Power/Volume - to be the white, the black APX NVFlash screen).
My suggestion is to do the stock recovery NVFlash Procedure again. Check
everything step by step to make sure the right files are there and the right
things done.
See if you can complete that and get back to a working bekit 1105 (Stock
Version 2638).
If you can do that, go into Settings/Display and set it so the display does not
turn off).
THEN, if it offers you the OTA Update, let it run.
If it is unsuccessful again, post back here and I will see if I can find the file
and instructions to load 3588 manually.
Hope this helps,
Rev
Ok so I reread Roebeets NVFlash post and double checked my files. All of them are there and in the correct location. I set up my USB drivers, booted into APX mode and ran the nvflash_gtablet.bat
Then the tablet loads properly into the stock TNT 2638. After setting up my WiFi I get a notification that the 3588 update is available. I download the update and after it ask me if I would like to apply now or later. I have tried both options however both seem to fail.
At this point if I hit apply now it shuts down the tablet however it does not turn on. The only way to turn it on is using nvflash_gtablet.bat file. Which it then boots up properly (and it is not wiped, it's as if it is jut turning on normally)and I either get one of two errors.
'The update to version 1.1-3588' was not successful. Please try again or contact customer support.'
or
'The update process cannot proceed due to an unrecoverable error. More information about the error is below, 'Verify checksum: file was not found. Downloaded file does not exist.null'
Hope this helps, I am not new to rooting/flashing roms but this is a completely new error to me.
Citi,
Did you do what I said about setting the display not to go off?
I tell people to do that because I have heard that it can
interrupt the download.
Whatever is happening, it seems like the download is not happening
or not finishing.
You can go to the Developer Forum (or there may be one in General)
and find the thread that tells where to download the .zip version of
the OTA 3588 download.
Then go down to end of the top 4349 thread in General and I wrote a post there for a
guy on how to install an update from the .zip file.
Rev
Yup I set the display to never turn off. However, it seems as if I have this problem http://forum.xda-developers.com/showthread.php?t=999832

get the recovery.img from from cwm .8 zip file and then use nvFlash to load that.
nvflash --bl bootloader.bin --download 9 recovery.img
(make sure you put the recovery.img in you nvFlash folder and then issue the command above. That will install cwm .8)
from what you wrote above it seems like you are getting stuck in apx mode when you reboot. So my question is what files did you download to setup your nvFlash????
I will attempt to load CWM using NVFlash, and I followed this guide EXACTLY http://forum.xda-developers.com/showthread.php?t=861950 for NVFlash for windows

which files did you download from his dropbox????? I am more interested in knowing if you used nvflash_gtablet_2010110500.zip or nvflash_gtablet_46_2010112600.zip????
I initially used that nvflash_gtablet_2010110500.zip and had the same problem as you few weeks ago. So I tried using nvflash_gtablet_46_2010112600.zip and that worked a lot better for me .
hope that helps...let me know if you stuck anywhere.

Unfortunately I tried out both with the same result
So the problem has changed from not being able to load an update to being in an APX loop? If I understand your original post correctly you were indeed able to nvflash back to original stock and boot normally. Then it failed when you tried to do the update to 3588. If you can still do that...
1) nvflash to bekit's 1105 stock
2) do not install the update
3) clear cache and data with Method I from: http://forum.xda-developers.com/showthread.php?t=1030915 - If this fails due to not being able to enter recovery then your nvflash was no good. You'll need to verify that you have the correct drivers installed, you're using the correct version of nvflash and that your image is sound. Easiest way to do that is to download them again.
4) install ClockworkMod .8 using MicroSD card method.
5) Re-partition 2048 and 0
Were there any error messages in the output of your latest nvflash attempts?
I posted on how you can get cwm .8 installed on your tablet if you are stuck in apx mode. There are also other threads that are pinned under the development section that explain how you can get cwm .8 using nvFlash. You will need that to get out of the apx loop that you are stuck in.

If the screen is blank then connect it to your computer and see if your tablet is in APX mode. You will probably hear the usb connect sound and you can go in device manager to see if it is connected. Let me know and then we can go from there
Yes it has been in a permanent APX mode since my original NVFlash, with the only way to turn the tablet on is to use the nvflash_gtablet.bat file. This will bring the tablet to TnT however my data has not wiped since my original NVFlash and the Wifi and other information is still present. It prompts me to download the new update however there is no need since once the tablet shuts down it will go to APX mode, with a rinse repeat of the cycle and I use .bat file to turn the tablet on.
ok try this...not sure if it will work but its worth a try
1. replace part9.img with the recovery.img ( i m sure u have done this already. this is so cwm .8 gets installed when you do a full nvFlash)
2. when you boot on for the first time.. press the power & + so you go in cwm .8.
let me know if you access cwm .8 if you do this ....we'll move forward from there
Failed first time I did it, but I just tried again and what do you know...success, unsure why.
Currently sitting in CWM looking at that beautiful green screen. I am in the IRC room if we could continue there that would probably work better and faster.
ya i m still at work and cant get on irc here :/...but if you are in cwm .8 then first thing i would do is wipe data then clear cache and then clear dalvik...then go under mounts menu and mount all the partiontions and then format all the partitions...once you are done with that i would mount your tablet so you can see is as a mass storage device on your computer and upload stock frimware 3588 on there...
use this link http://forum.xda-developers.com/showthread.php?t=861950 and go down to post nvflash and get the 3588.zip
from the 3588.zip get the update.zip and copy that to your tablet...once u have that go to the main menu of cwm .8 and choose the option to install update.zip form sdcard...i thikn thats the second one down
try that and see if it works...if not then i'll on irc in the evening today and i'll help you out ...dont stress we'll get your tablet up and running again

[Q] Help! Can't even use NV Flash!

Used NVflash last night to install CM. Almost immediately there were problems. I was able to boot in CM recovery only once. After that, I could only get to apx mode. Tried to flash again this morning using NVflash and now my tablet won't connect to the PC at all even in apx. Can anyone help? I can't even get the PC to read the tablet at all so I can't transfer files or anything.
EDIT: Finally got into CM Recovery. Did a factory wipe and still can't connect to my PC. Please help!!!
Some severe APX loop problems can look like a completely dead tablet. The screen might not light up at all but you might still be in APX mode. Check to see if your charge light comes on when it's plugged in. If that works then hook it up to your computer and check to see if it's in APX. If it's not press the power key for 2-3 seconds and check it again. You might find that it's just being stubborn.

bricked??!!

i have a gtab and it is giving me a headache already trying to figure out how to fix it. I have search high andd low for a solution but havent quite found one, yet.
This is my brother-in-laws gtab. For some reason he tried to flash to a different rom and update the tablet. Right now, the tablet won't boot. It gets stuck on the 3 bird screen. If i try to go into recovery, i still get the 3 birds with the "detected a recovery key pressed."
What i have done...well since i can get into apx mode, the first thing i did was flash nvflash 1.1, that should clear things up, then i pushed recovery. But that didn't work, i am still at the same place i started. So i flashed nvflash 1.2, still didn't work. I re-downloaded the files again from different sources and tried it again, and again, and again. I have tried it atleast 6 times but all with the same outcome. I am still stuck at the 3 birds. I tried holding the + while in nvflash to boot into recovery but that didn't work either. I am fresh out of ideas. Everything i read tells me to wipe cache/data, but i can't even get into CW. And nvflash isn't working for me either.
I am still on the same screen, this darn gtab is giving me the bird three times over. so right now i am going to allow the battery to drain then try again. unless anyone can suggest anything that will give me some hope....or even to tell me that i have bricked the "unbrickable."
oh and everytime i do the nvflash the device does not reboot itself...it stays stuck on the "entering nvflash recovery mode / nv3p server"
I had a similar issue with my gtab except I keptrebooting into apx mode. I then downloaded some nvflash from roebert that said deprecated not use (in a dropbox) and flashed that, my gtab came back to life there... funny thing is that I'm pretty sure I ended up on 1.0, luckily I was able to flash came from that and it's all been good from there.
I would say give that a try, then again I'm relatively proud to say I'm a n00b at Modding these things so tread carefully.
PS : as unbrickable as the gtab might or might not be it can (and to me it is) quite frustrating ; so I feel your pain

I am still on the same screen, this darn gtab is giving me the bird three times over. so right now i am going to allow the battery to drain then try again. unless anyone can suggest anything that will give me some hope....or even to tell me that i have bricked the "unbrickable."
oh and everytime i do the nvflash the device does not reboot itself...it stays stuck on the "entering nvflash recovery mode / nv3p server"

You're a code red. You've been missing a very important step. Please follow instructions precisely.

I have done every step on both code red and code double red...code triple doesn't apply since i can still get into apx mode. either way, after i flash nvflash the tablet does not reboot it stays at the nv3p server screen. If i turn it off and back on again the birds come out again. i have even held to the volume + during nvflash and it shows the nv3p server, detect a recovery key pressed, and booting recovery kernel, but no go...it's just stuck...i can turn it on and off, i can get it in and out of apx but it will not reboot after nvflash or boot up a rom or clockwork recovery.
btw, i do have my own tablet as well and i ran nvflash on it just for giggles, and it works as it is suppose to. After it flashes it boots up to tap n

Try code detox, you need a pc/laptop and load the proper driver, run the bat file from the directory. This mode completely reload all the petitions and usually fixes the issue. I think your boot petition is toasted.
Good luck.

This is not normal...
I did the detox and i DID get the "magic value mismatch" in the apx mode. But then i loaded the nvflash it is still in the same state as it was before...not loading recovery, booting, i can only get into apx mode...this is really weird..
I did the detox with both nvflash, 1.1 & 1.2, with and without Clockwork, but none worked. I can do the nvflash "format" and i still get the mismatch message but redoing the nvflash to get the tap n tap stock image or heck even not seeing the darn birds it won't do...
I have even taken it apart, let the battery run out, pulled the battery, pressed the reset button...but nothing!
I can't push anything in adb since i can't boot or get into clockwork...i think the tablet is offically bricked...i have ran out of ideas and have read many...i

I just tried ... and no cigar... i can go all the way to step 2.1 but it won't boot to recovery...it stays at the apx "entering nvflash...recovery key detected...booting recovery..."
to me it seems like it is not retaining any of the info that i am pushing onto it...like a "bios" is being reset and not remembering what to do...
A new error message.

Edit: i reflashed nvflash 1.2 and got rid of the error message...but i am back at square one...but taking a look at the error and from what i am seeing the tab is not finding the kernel image to start recovery. but why?

Did you (or anyone else) discover the "secret" here? What did you do?
Unfortunately, I am now experiencing EXACTLY the same issues. My processes have fixed tons of GTabs that people thought were bricked. I *THOUGHT* that there was no way to HARD-brick the device but I may have been wrong!
I really need some help here. Anyone have an answer?
You could install a copy of Ubuntu and try nvflash with that. That would eliminate any possible driver issues since Ubuntu does not require drivers for apx mode. From the error you posted earlier "entering nvflash recovery mode / nv3p server" it would appear nvflash is not actually flashing anything.

Thanks for the comment. I agree about Ubuntu. I use it exclusively - have for a couple years. I did all my testing and attempts with it. I finally decided to build a WinXP machine and I am now trying to use it.
You are correct about NVFlash not saving anything to the device. There is no bootloader and although all of the NVFlash commands are "successful" it just does not save.
When I try to use the external SDCard to run recovery, the GTab does not seem to recognize it. It acts just as if there was not a recovery file on the card.
One thing that seems to give me some hope. I am seeing the USB connection (while not in APX mode) with the Windows Machine. So, I will install ADB and see if I can grab control that way. But ADB is such a bugger with Windows.

[Q] ViewPad E100 - Stuck at boot screen

I was having trouble with ADB on my newly acquired ViewSonic ViewPad E100. I thought rooting it and/or installing a new OS/ROM might help.
I saw this thread:
http://forum.xda-developers.com/showthread.php?t=2021203
Where someone pointed a guy to a universal root tool:
http://forum.xda-developers.com/showthread.php?t=1886460
I got the tool to run, and tried to use the #1 - New Standard Root - it got as far as to reboot the device.
Maybe I wasn't in trouble yet. But I waited for a bit and the device was still on the "ViewSonic" boot animation. I stupidly pulled the usb plug out to check out the device closer. It didn't boot. Then I restarted. I can no longer get farther than the "View Sonic" boot animation.
Okay, I know there's some special boot methods in Android, so I try a bunch of key combinations. Power+volume down doesn't seem to do anything [yet] but when I press Power+volume up, I get the android guy with a red exclamation in his belly:

It's possible I see a flash of a better image, like this one:
http://www.android-hilfe.de/attachm...ery-rotes-warndreieck-2012-09-22-03.41.16.jpg
So no idea what to do. I figured it couldn't get much worse, so put a recovery "update.img" for a gtab on an SD card and then tried to reboot, with holding vol+power, just power, no luck with any combination.
Then I discovered 'nvflash'
http://raywaldo.com/2011/01/nvflash-for-dummies/
I think I'm following the steps right (for a gtab at least), but I can't get into APX mode. I can get *something* when I hold vol-down+power, I actually get my computer (Windows) to show me some internal storage of the device I guess... There's no way for me to install APX drivers, and I don't see the screen "flash" either, just sometimes I get USB storage attached.
Can I recover from this? Are there any more things I should be trying? Does anyone else out there have this device? Where else can I look for help? I just got this device this week and was hoping to use it for development!
Thanks in advance.
