[Q] WSOD brick - G Tablet Q&A, Help & Troubleshooting

I have really enjoyed -and appreciated!- the work that folks have done here...been using this forum a lot since Oct - thanks!
But now I could use some help. I've managed to brick my gtab to the WSOD. I've searched and tried -several times- the different unbrick methods, particularly nvflash, but no avail - I must be doing something stupid/wrong.
The gtab boots to a white screen, whether 'normal' or 'APX mode' boot. If I connect with nvflash, sometimes it reads the USB drive, sometimes not (using Vega drivers under Win7/64). USBDeview shows an active connection as storage device.
Nvflash starts flashing, then (apparently) hangs; after 15 minutes, no change....
Since everything's white on white, all I can do it go by the 'symptoms' on my PC.
I didn't see anything specific to this in searches, and have tried (all?) other methods in the threads....
Anyone have any ideas?
Sorry to make my thread be a request for help, since I've really enjoyed lurking on the XDA boards for some time.....special thanks to you, Roebeet!
Thanks,

I'm no expert but I've had to use nvflash a few times already
APX should be a black screen (backlight off).
I assume that you can't turn off the tablet by holding the on/off button
for a long time (around 8 seconds or so)??
Perhaps you should let the battery run down completely until shutdown
(if the screen is locked on that shouldn't take all that long).
then try apx/nvflash again ...

Thanks for the fast response....
1. I have used APX mode before when it was a black screen...that's not happening, now. But I can power/+ and it boots into a mode (albeit white screen and possibly white font) that nvflash recognizes and proceeds to flash...or so I think.
2. I have tried full-power-drain to where there's no response from the unit at all, until I charge it, at least a little. Have done that several times, no difference.
3. when I turn the unit off (holding in power button), it will turn off.
If I power up in 'WSOD APX' mode, and keep holding the power/+ buttons, it will eventually toggle off (black screen) for under a second, then start up again with WSOD.
Pretty brick.
Thanks again for any/all advice.
Marc

Power on and Volume Up is Recovery Mode, which is why the screen isn't going back off like it should.
Power on and Volume Down is APX Mode. Try this and nvflash.

Sorry for the error - and thanks!
When I go into APX mode (-), nvflash will start and then hang (no response). I must be doing something dumb/stupid (like the power/+ (!)), but it's hung.
Thanks to all for your continued help...

You're welcome. I don't use windows for nvflash so I can't really help there other than to say to make sure you have the correct driver loaded and use the bekit 1105 image.
This: http://forum.xda-developers.com/showthread.php?t=861950
is your best bet for referencing what you need.

Yep...used that/those, as well....
Maybe I'll just boot up Linux and see if that'll work....
Thanks for your help

I've found Linux to be much easier for me ;-) Let us know how it works out.

Thanks - I've now tried it several ways, including Ubuntu and W7/64....
bat file now executes, creating partitions and copying img files, and ends normally. At that point, the driver loses the connection and then regains it. There is no change on the gTab screen, even after 5 min.
Powering back on -normally - goes back to WSOD, with a flash of black screen (less than a second) about 30s into it, then return to WSOD (although dimmer). Stays there (stopped it after 5 min).
Powering back on into Recovery mode - same symptoms as normal power on.
Anyone have any ideas?
Thanks again for everyone's time and consideration!

Is my phone bricked?! (grey battery screen)

Hi guys,
I figured I'll post again here since I think I bricked my phone.... I was trying to install Eugene's Vibrant6.zip and I got stuck on the Vibrant Logo with Samsung at the bottom. I tried to reset with both volume buttons and power button and got to grey battery and nothing else...
What I did prior to this was I formatted system and data on the recovery screen as per some posts here and it would just boot into a loop. Windows won't recognize a device and it just shows grey battery image and it doesn't seem to be charging. Anyone can help me?
EDIT:
Out and in the battery, plugged in to USB and it just loads the battery image and it's all grey color as if fully discharged and just stuck on it. Device is also not found in my system so I can't do any adb commands. If I just reset it without the cable it would just sit on the Samsung boot loop. Anything I can do?
UPDATE: Ok, some good news! I heard the sound as it connected via USB, I can see the 2 drives, but they read as Removable Disk and I can't access them...
adb reboot recovery or download
error: device not found
What if simply format the drives via Windows right click menu? Will that do any good or bad? What are my options here? Any help will be appreciated!
UPDATE: Well... looks like this is pretty much a dead phone.... I right clicked and selected Format in My Computer and it just says There is no disk in Driver F: Insert a disk and try again.
Can I a mount an image somehow via MagicISO? Or is there something simpler that I just can't figure out?
Again, thanks for your help!
Thanks.
Has anyone experienced this or am I the only one?

Sorry I have never heard of this or witnessed it while flashing anything to my device. Obviously the battery screen signifies that the phone is off but is in charging mode and hitting the power button will boot the device up. (I'm sure you already know of this). Never heard of it being stuck at that screen after flashing. Hopefully you can get this solved soon. Good luck

Slow down for a second. Your phone is definitely not bricked. Ive been over the edge, and been able to bring my phone back to life.
To clarify, you flashed vibrant6.zip through clockwork mod, and then the phone got stuck on the samsung S? How long did you let it sit there?
It sounds like just your ROM is messed up.
Are you able to "get into recovery"? Holding both volume buttons while you power on the phone, without it being plugged into usb.
Do you have Odin? And have you ever used it?
Its totally frustrating when your phone gets messed up and you don't know what to do.
I flashed the stock ROM via Odin and then wanted to install Vibrant6.zip. For that I entered into a recovery mode via Clockwork and as someone in the other thread advised, I formatted system and also data, don't recall exactly. Then it looped to a standard recovery mode and I just rebooted the phone. This is where it got stuck... Vibrant in the center and Samsung at the bottom of the screen. To test it I left it like that from night till this morning. In the morning I woke up it was on the same boot screen.
Before that at night, after seeing it hand at the boot, I held both volume keys and power, waited for it to reboot, and immediately it showed a circular progress bar, but not moving just highlighted the 12 o'clock bar and second later I see the battery image all in gray and nothing else. It just sits on that grey static image without actually charging it (no green section or flashing dots)
Boot logo only appears if I am trying to reset without the USB cable. On the boot loop I plug in the cable and I hear the USB connecting it, I see the 2 Removable disks, but both inaccessible and adb commands don't recognize the device.
Very weird, as in turned off mode it's not charging at all.. just shows this grey battery image with a circle progress froze on 12 o'clock bar.
That's pretty much it.... I was never able to enter into recovery nor download via the buttons. It would just always reboot into this grey battery screen....
Completely helpless.... I did order a new battery from TMO, maybe the battery is fried and that's why it's not charging and just sits on this stupid static grey battery screen.

Holding both volume keys and releasing power once screen goes blank, only show Vibrant logo again... I have tried this a million times
With USB cable it shows grey battery screen, without the cable just a Vibrant boot loop...
I'm assuming that you have the Samsung drivers installed.
Try the following steps:
Take out the battery and then put it back in but don't turn the phone on.
Plug it via USB.. does anything show up on the screen?

Yes, I have the drivers installed as I was able to locate my device and use adb commands to enter into recovery and download. Also Kies worked.
Doing what you asked simply load the grey battery image and nothing else with a progress bar not spinning. Just sort of hangs on this image and that's all.
Booting without the USB cable loads the Vibrant boot loop. Connecting USB at this boot loop state, would play a sound as if it connected to my windows, but I can only see Removable disks that are inaccessible and adb doesn't find the device...
Very strange.... trying to use the button keys to enter into recovery or download is no use, as that just won't ever happen, even when phone was working fine.
Any other suggestions? I would return the phone for replacement... but I am not sure how it would look with all the files still on the internal disk including root if I am not mistaken... I had only few hours of sleep because of this headache

Are you sure that you're doing the right things to get to download? I've been in this situation and I wasn't able to get into recovery but I was able to get back into download mode.
I believe if you return it back and they find out it was rooted, they will charge you for it. If not, it'll appear on your bill.
I'm sure that you're doing the wrong things to get into download mode. If something is appearing on your screen it is a soft-brick and you're not bricked.
1. Take out battery, put it back in. (to turn the phone fully off)
2. Don't turn it the phone on!
3. Plug the phone into your PC, do not hit the power button!
4. See if the phone shows anything on the screen (powers on its own when plugged in)
IF the phone screen does 'turn on' after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold the volume up and volume down buttons.
6. Hold the power button as well as the volume buttons until the screen goes black.
7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons!

A tip to get into download mode is to put the phone HORIZONTALLY (sideways) and it will make it a lot easier.
I am pretty much positive about it. I know a lot of people can easily enter into recovery or download modes, but I know many can't and I am one of them. It would just load the grey battery image instantly as I let go of the power button.
1. Take out battery, put it back in. (to turn the phone fully off) DONE
2. Don't turn it the phone on! DONE
3. Plug the phone into your PC, do not hit the power button! DONE
4. See if the phone shows anything on the screen (powers on its own when plugged in) FIRST THING THAT APPEARS IS A CIRCULAR PROGRESS BAR THAT CHANGES TO A GREY BATTERY IMAGE WITH A BAR IN THE MIDDLE OF IT. STATIC IMAGE, NOTHING ELSE.
IF the phone screen does 'turn on' after being plugged in without you hitting the power button, so far so good.
5. Now while it's on like this, hold the volume up and volume down buttons. DONE
6. Hold the power button as well as the volume buttons until the screen goes black. DONE
7. As soon as the screen goes black, let go of the power button! But DON'T let go of the volume buttons! DONE
THE STUPID GREY COLOR BATTERY IMAGE APPEARS AS BEFORE....
I'm thinking maybe battery is fried and that's why the grey color screen appears and not the usual screen where you see the battery charging...
After reading this thread it's clear that my handset is one of the new ones that have recovery/download modes disabled via the volume+power buttons.
So that pretty much covers it... I hope TMO will not ***** about the files that are on the internal sd that I am unable to access and remove... unless anyone else has any fresh ideals how to gain access to the disk
I think I might have a similar problem.
I accidentally deleted the touchwiz framework so I can't do anything ON the phone. It boots up, and gets me to the lock screen. As soon as I unlock, I am greeted with dozens of unending force closes.
I can get into both download and recovery mode, however, I have not been able to get ADB to recognize the device. I am attempting to push the stock ROM to the internal memory to flash over everything.
I'm not sure what to do to get ADB to work but it's driving me nuts!
Stuck at vibrant? I have a fix
Check out android Dev Section... I figured out how to access download mode or stock recovery mode when you are stuck at the vibrant screen!!!! BACK IN BUSINESS VIBRANT OWNERS!!!
i got the same problem and nothing seems to work
Try this out http://forum.xda-developers.com/showthread.php?t=1103706
Feels like I'm having same issues..
the previous post requires opening the phone and I don't have tools for that..
Here's my issue.
I can't get into Recovery or Download and computer won't see phone to Odin.
I've got drivers installed and AIO Toolbox as well as ADB(which won't work because of computer not seeing phone.
Using the manual option(vol+ vol- power), nothing works.
I've done all the tricks like unplug it then hold vol keys plug it insert battery..
When I do plug in the phone to to even just get a charge in it goes the the battery, but my is is frozen or something. doesn't turn green or have a charging animation. After about a minute or so it was start up and boot loop. I read something about a bad battery? I've got two of them and they seemed fine before..
Before all this I had to Odin and go to stock. I was attempting to get ics back but I was being lazy and trying to do as little as possible..bad idea. I was following slim ics install and flashed cm9 daily, slimics and commons..and now this..
I'm not sure what to do..I usually search around xda or google..10 hours later.. idk..Anyone able to give help please?

Try asking another question. But I suggest using a USB jig. They usually work. Then odin
Sent from Mount Olympus via Hermes
Did you ever get it fixed man? I literally did the very same to mine a while back and It works like butter as we speak. It is fixable with a mini-usb jig or dongle. You can make your own with about $3 worth of parts from radio shack but I recommend buying one, it will be easier. I for the record made mine simply twisting together the resistors and though it was tough to touch the right pins it did eventually work and get me back into download mode.
Hopefully you already got it fixed though. If not I can help you out.

TnT Lite issue

I had installed TNT Lite v 4.3.0 a couple of weeks ago and it was working pretty good. But today my tablet has gone into a bad state. Every app that I run results in FC. Even the ADW launcher EX that I had selected default is crashing. It then gives me the options: ADW Laucher, ADW Launcher EX, and the regular Launcher. The plain ADW Launcher also fails, but fortunately the regular Launcher still works so I can access the apps.
But unfortunately almost every app that I am trying fails. The only one that doesn't fail is the Web browser. The Settings starts and I can access Applications menu but once I choose say System Applications, after that if I try to choose some other option such as Installed Application, it crashes as well.
Last night however when I started the tablet the battery was probably down and while it was powering it up, it turned off and then restarted by itself and then turned off, without reaching the lock screen. I don't know if it has something to do with all this.
What do I do now? Any help will be appreciated.
Thanks.
A well known issue.

This is why I'm an advocate of people doing the partitioning right before they flash their first custom rom. This way, they won't have to wipe everything later on.
I could only wonder why people aren't mentioning this in every custom rom thread.
Thank you so much. Will try it out tonight.
Unfortunately it seems I have run into a worse issue (without even doing anything yet). Now when I power it on, it starts and shuts off within a few seconds, just shows the birds for like 5 secs and bang, black screen.
The tablet is fully charged (if I put it on charge the light turns green in no time). Looks like the battery is dead.
You might be dropping into APX mode. Do you know how to use nvflash?
Thanks for the reply. You are absolutely right. After multiple tries it did boot up and I was able to install clockworkmod and it all worked great. It wiped off everything but I could live with that. And I turned it off and back on and it was working fine.
But then it went back into the same mode - shutting off immediately after turning on. I decided to return this tablet thinking that it is bad. But before I would do that I thought to restore it or else Viewsonic won't honor the warranty. So I started reading the thread about restoring the tablet to stock using nvram flash. In that procedure it requires me to put the tablet in APX mode and that's when I thought that maybe it is going into APX without pressing the volume - button.
Anyway I was successfully able to flash nvram. Or so it said. I still have the output from the batch file. But now my tablet is totally bricked. It does not boot at all. No pretty birds for me.
I hope there is some way out of it. Please help.
Edit: After re-flashing and using a different file, it seems to have made it a little better. At least I am seeing the birds again. But the original problem of shutting off, or going into the APX mode without pressing Volume button, has returned. All I am getting is the birds for a few seconds and then black screen. I will continue to retry, and if I see it booting up successfully to the stock, this thing is going back to the factory.
1) What image did you use to nvflash?
2) What happened when the flash was finished? Did it boot normally at least once?
3) Does the screen just stay dark all the time now?
1) First time nvflash_gtablet_46_2010112600.zip and after that it did not boot at all. Only black screen. I flashed it couple of times, no avail. Later I flashed nvflash_gtablet_2010110500.zip. This at least recovered it enough that it shows the birds, but soon after the screen turns black. I have confirmed that it is going in APX mode. If I have USB cable connected to my PC, the PC reports discovering the NVIDEA APX device.
2) It hasn't booted normally since I flashed nvram.
3) No I get the birds, but after that it turns dark.
Ok. Using Bekit's 1105 image...
1) Replace part9.img with the recovery.img out of the clockworkmod installation zip.
2) Put the tablet into APX mode.
3) Type in the command to start nvflash but before you hit the enter key hold down the Volume Up key and continue to hold it down until the flash finishes.
4) The tablet should boot into clockworkmod recovery.
5) Repartition 2048 and 0
6) Clear everything (cache, data and dalvik)
7) You might need to re-nvflash at this point.
Thanks for your response. I tried it. Did not work. When you say Replace part9.img with the recovery.img, does it mean copy recovery.img into the NVFlash directory and rename it to part9.img or leave it as recevery.img. I renamed it to part9.img and backed up the original part9.img to part9.img.tmp. The size of recovery.img and the original part9.img are very different. I am confused. Please help.

Yes, that is exactly what I meant.
Are you sure you're holding the volume UP key? Birds and then black screen is APX mode which is normally entered by holding volume DOWN.
Well it goes into APX mode even if I don't press any Volume button at all. That is the problem I am trying to fix. When I press power button (without touching the volume button) the birds come and then black screen. And this is APX mode because if I am connected to the PC it brings up an NVIDIA APX device on the PC.
Now if I press the Volume UP button along with the power button, nothing happens, not even the birds come up.
So the fact that the recovery.img (3.7k) is much smaller than part9.img (16k) is ok? Or I am doing something wrong.
Any ideas?
I was thinking about formatting the gtablet. Please let me know if this is the right move, or there is something else I could try first.

A little more than "It did not work" would be helpful.
What step failed? Please tell me what happened after each step.
Did you get into CWM and repartition?
Did you get everything cleared?
What happened when it rebooted?
What was the original filename of the image you tried to flash?
What version of clockworkmod do you have installed?
Have you ever used ROM Manager?
All of this is important and no one can help you if you don't provide enough information.
Oh, I am sorry. Here are the answers to the questions you asked:
What step failed? Please tell me what happened after each step.
Ans: Out of the 7 steps you provided, the steps 1, 2 and 3 worked fine. It is the step 4 that failed (and of course I can't proceed with the steps anymore). In other words I cannot go into clockworkmod recovery.
Did you get into CWM and repartition?
Ans: No I was not able to do so. If I press power and Volume Up key at the same time, nothing happens, screen remains black, not even birds come up.
Did you get everything cleared?
Ans: I believe you are referring to step 6. No, I could not get to that step.
What happened when it rebooted?
Ans: Nothing showed up. Because when Volume Up is pressed while it is powered on, nothing shows up on the screen.
What was the original filename of the image you tried to flash?
Ans: Actually first time nvflash_gtablet_46_2010112600.zip (and this is before you provided the 7-step recipe - see post #6, 7, 8 of this thread) and after that it did not boot at all. Only black screen. I flashed it couple of times, no avail. Maybe that was my mistake. I chose a wrong file. Later I flashed nvflash_gtablet_2010110500.zip. This recovered it enough that it shows the birds now, but soon after the screen turns black (goes into APX mode).
What version of clockworkmod do you have installed?
Ans: v08
Have you ever used ROM Manager?
Ans: No. What is it?
I really appreciate your help.
What happened at the end of step 3?
Did you start holding the volume UP before you pressed the return key for the nvflash? If not... go back and do it again.
Did you continue to hold it until the flash was happening? You must continue to hold it down for at least 5 - 10 seconds after the flash starts.
When the flash was done did it say "Recovery Key detected" on the screen? If it didn't say this that is an indication that you didn't hold the volume UP key long enough.
If all of the above was done correctly and did happen but you didn't get to clockworkmod then what did you get? Did it look like stock recovery?
It sounds to me like you did the nvflash then tried to reboot into recovery.
Its unbelievable. Tonight when I powered it on it started booting up normal instead of going into the APX mode. I was glad. The stock UI came up, but some of my apps like Quadrant, File Expert etc were still there. It also notified me of the Update 3588. So I downloaded it and started installing it. Pretty soon it rebooted itself (sooner than I thought - I don't know if the remaining installation was supposed to happen after the reboot).
But instead of booting up into 3588 it is unfortunately gone back to the same old issue - the birds followed by black screen - aka APX mode. It never booted up after that. No matter how many times I tried to reboot, it goes into APX mode just like before. I don't know what caused it to complete bootup. One thing I noticed was that the battery was totally drained when I started tonight. I don't know if the drained battery somehow took it out of the APX mode. But now it has a little bit of charge because of hooking up to power supply. I have disconnected the power supply and will leave it in APX mode over night and try it again tomorrow when the battery would be totally drained and see if it boots up fully.
To answer your questions though:
What happened at the end of step 3?
The screen went black and after that it stayed black. No CWM.
Did you start holding the volume UP before you pressed the return key for the nvflash? If not... go back and do it again.
Yes, I did.
Did you continue to hold it until the flash was happening? You must continue to hold it down for at least 5 - 10 secondsafter the flash starts.
Yes, I continued to hold it all the way until the flash completed and the screen went black and quite some time after that.
When the flash was done did it say "Recovery Key detected" on the screen?
I don't think it did.
If it didn't say this that is an indication that you didn't hold the volume UP key long enough.
So I guess I need to give it another try. Tomorrow I will try to reboot the tablet again and if it continued to go into APX I will do the nvflash one more time.
If all of the above was done correctly and did happen but you didn't get to clockworkmod then what did you get? Did it look like stock recovery?
A black dark screen. No CWM or stock recovery.
It sounds to me like you did the nvflash then tried to reboot into recovery.
No at the time of nvflash I held the Volume UP button and nothing happened. Since then I have been trying to bootup or put it in CWM Recovery but only thing the tablet wants to do is go into APX mode.
So I guess my theory of "drained battery takes it out of the APX mode" is correct. I tried to reboot the tablet several times but it just kept on going into the APX mode until the battery was completely drained. And then it started booting up normally but it went into some installation (probably the stock 3588 that I had downloaded in the previous successful bootup). And then the green android with the exclamation sign came and the exclamation sign was rotating for a second or two and then stopped. And it looked like it was hung. I waited for a minute or two but nothing happened, so I pressed one of the buttons, I don't know if it was Menu or Back button, and all of a sudden clockworkmod recovery screen came up.
I have attached the picture of the screen. It still shows the green android with the exclamation sign in the middle of the screen, along with the CWM Recovery.
One other thing I noticed and I am not sure if it is normal is that if I choose say Reboot System Now from CWM menu and it shows like 10 entries with many No's and only one Yes. I can only use the volume Up + button to go down, if I try to go up using volume Down - button it does not go up. Is that normal? Is the only way to go is go down using Voume Up button in CWM menus? I have a feeling that my Volume Down button has gone crazy and it is not functioning properly and that is what is causing it to go into APX mode at the startup as well.
Anyway I first attempted "Apply SDCARD:update.zip" hoping that it might continue with the stock 3588 installation, but that failed. You can see the messages in the picture. Then I tried the Factory Reset and it was successful. I then rebooted the tablet. But now again it keeps on going up into APX mode. I will have to wait until tomorrow for it to completely drain battery again and then try to reboot again.
Any ideas? I know it is overwhelming and the behavior is very weird. At this point I am trying to bring it back to the stock firmware so that I can get this tablet replaced under warranty.
There are quite a few things that are not acting normal from what I see here.
Did you try to repartition 2048 and 0? If not, I would start with that then I would format everything and re-nvflash a stock ROM onto it. That might clear things up. If not you could be looking at a hardware reset.

[Q] Can't boot into clockworkmod

Hi all -
I was attempting to load Cyanogen onto my Gtab. Seemed to be going well. I downgraded from TnT 4349, got clockworkmod on and tried flashing CM. Not exactly sure what happened but I never got CM running.
Now I can't boot into clockworkmod after running nvflash. Tried it dozens of different ways. Here's the cycle of what currently happens:
I power down my Gtab. Put it in APX mode (Power + Vol Down). Hear USB connect on my computer, dont' see the birds logo, just black screen.
Run NVFlash batch file. Gtab screen comes on, "Entering NVFlash recovery mode / Nv3p Server". NVFlash runs successfully according to its read outs.
Gtab reboots, goes through loader screens, and is up and running. TnT works fine.
Power down. Try to get into recovery (Power + Vol Up). Hear USB connect on my computer, nothing happens. Black screen. If I press power again, I hear the USB disconnect sound. If I hold it down for 10+ seconds, I hear the USB disconnect sound, a short pause, then the USB connect sound again.
Lather, rinse, repeat.
I've tried flashing every version of TnT I can find, with/without clockworkmod, nothing works. As soon as I power down my device, it won't turn back on. Just a black screen and the USB connect sound.
I've been searching xda-developers for a solution for days now. Every fix I try that sounds remotely like my problem has not worked. Tried the FORMAT Nvflash as well.
From what I've been reading, it sounds like I am "stuck" in APX mode. Is there any way to definitively get out of APX mode?
Running Windows 7 64 bit, going to try the process from Ubuntu but not very hopeful it's going to make a difference.
Any help would be sincerely appreciated!
Spoke a little too soon...
I must've finally entered the magical combination of search terms, because I finally stumbled across this post:
http://forum.xda-developers.com/showthread.php?t=1038689&page=12
K J Rad's method got me part of the way there... The big secret is:
Hold down the Volume Up before running NVFlash, and keep holding down for a few seconds after it starts.
Once NVFlash finishes, my GTab displayed that a recovery key had been detected! And I got into recovery!!
NVFlash hung up on Step 9 of Part II... and I started to panic... But after another round of repartitioning, clearing data/caches, and a little more fiddling... I am now the proud owner of a GTab running Bottle of Smoke Honeycomb! That reboots and everything HC is bad a$$... A little shaky stability wise but awesome to see what's to come.
Much thanks to this forum and all who spend their time troubleshooting tricky devices like these!

[Q] G-Tablet - boot loop? - Need help!

So a buddy of mine bought one of the Viewsonic G-Tablets, and attempted to root(if this is the right term), and I think he may have bricked it. After reading many threads here, and watching some videos, I'm quite confident now that we could get it back to working order, but after hours upon hours of attempts, I cannot seem to solve the issue.
Model: UPC300-2.2
OS Ver: 2.2
Tap UI Version:
1.0-2638
Kernel 2.6.32.9-00000-10.8.2-dirty
Build: FRF91
As of right now, the damn thing will not turn on outside of recovery mode. If you try and power it on, the screen never powers up.
If I power up in recovery, I also don't get a power up screen, until I run NVFlash. After running NVFlash, it will create partitions and boot up into the OS. Every functions at that point, but if I turn it off, and turn it back on, it repeats its previous offense; no screen power.
When I turn it on though, although no power, it does make a bing on my PC, to indicate USB is getting feed, but it does not try and mount the device.
I am not positive what he has done to get it into this mode, or what I can do to get it out of this mode. I've tried a handful walkthroughs and troubleshooting threads but they have not resolved this problem. Is this common? What are my steps to try and resolve it? He's coming up to the end of his RMA time, and he will soon try and see if he can RMA it, so I don't have a lot of time to futz with it, so I'm reaching out for help.
If there is any other information you need, please request, I just posted the basic info I found on the About tablet page
Thanks!
Can anyone confirm if this is an actual boot loop? What would make it so I have to nvflash each time to load this tablet; is it fixable, or is there an issue somewhere else with the device, that may just mean its bricked.
when you try to boot into recovery are you holding the volume up button and the power button at the same time untill it boot into recovery if it does boot then you need to wipe user data and wipe cash if not try to load clockwork mod do a search in the main viewsonic fourm to learn how to do this I hope this is some help Good Luck

[Q] Bricked phone - Boot loop - Recovery & Download mode not working [HELP]

Hello guys,
I've got a big problem with my I9300 and therefore I would like to ask here for any help. (If I'm in the wrong section, please move the thread to a correct one)
I had installed the Resurrection Remix ROM, v5.2.6. from 30.12.2014 and Googy-Max 2 recovery (CWM based) on my phone. I was using it for days and all worked fine.
One day I turned the phone off and I wanted to restart it. But it never restarted again; it ends up in a boot loop. It shows me the white Samsung Boot-Logo for some seconds, then a total black screen and the same thing repeats in a loop.
So I wanted to get into the recovery for wiping etc. but I couldn’t access the recovery. Nothing happens by pressing the relevant buttons. The device is still hanging in the boot loop. So I wanted to flash via Odin, but this isn't possible. I also can't go into the download mode. After pressing the relevant buttons, the green warning screen appears, which asks me if I really want to go to the download mode. But when I press volume up for "continue" or even if I don't press anything, the phone turns off and the boot loop with the white Samsung Logo starts again.
Therefore I ordered a USB JIG for forcing the device to go into download mode. When I plug the USB JIG in, the device actually goes into download mode but this status holds on only for a few seconds. After accessing download mode through the JIG, after a few seconds the phone turns off, restarts, (and because the JIG is still plugged in) the download mode appears again and it ends in a loop.
At first I thought maybe the power button is sticking and therefore the device turns on and off autonomous. But definitively I can negate it, because I opened the phone and removed the power button and nothing changed. Also by pressing the power button on the mainboard I can clearly hear the "click".
So I started a new attempt. Although the time, in which the device stays in download mode before turning off, is very short (only a few seconds), I tried flashing an other recovery, namely TWRP v2.8.3.0. So I prepared ODIN, plugged the JIG into the device, by appearing the download mode I switched cables and an other person clicked start at ODIN and it worked. So now TWRP is installed. Now I also can't get into recovery but after flashing TWRP there exist two little differences. First, after pressing the relevant buttons, TWRP appears for less than 1 second until the phone turns off. Secondly, when I plug the device in for charging, the Samsung charging logo appears for some seconds, then for less than 1 second appears a charging logo from Lollipop and the device ends up in a loop by displaying alternately the two different charging logos. Before flashing TWRP, the device booted in a boot loop (as I wrote above) by plugging it in for charging.
So the main question: how can I get my device work again
I tried telling you all details so that you have a better view of the problem.
Maybe I should flash a fully (stock) rom, but as I told you the download mode appears only for a few seconds. Flashing a recovery was possible, because the recovery file is very small - 7 MB. A full rom is much bigger and I think by flashing a complete rom, the device would turn off while Odin is flashing, therefore I ask first here for any assistance.
Thank you very much in advance!

Check and make sure that your volume buttons and home button are not stuck also. If they are not, I would suggest a visit to a repair shop as your EMMC chip might be weak already.

Your power button is failing, stuck in 'pressed' position. Try pressing repeatedly power button for several seconds, then release it completely. It shall bring it back to life. Visit your local service, or prepare tin, heat gun and soldering pistol. One button cost $0.2, they are selling them on eBay in sets of three (and 10, and 100....).
Happened to me some time ago, and video on youtube helped me to dismantle my phone, pull broken button out of it, and change it for new.
My phone was cycling like yours.

As said your emmc chip maybe failing.
The dead boot thread maybe of interest to you.

He said he has tested this and can also hear the micro-switch clicking.

Thank you very much for helping! :good:
So the question is, whether it's the power button's or emmc's fault...
I did a little searching and found this video. I've got exactly the same problem like the guy. At 1:06 following the boot loop, at 1:34 following the problem with downlod mode.
Although he thinks it's caused to the sudden death problem, but at least in my case I think it's wrong because months ago I did the eMMC Brickbug Check.
Also I noticed a probably important detail. When I put the battery in the phone, it automatically turns on without pressing the power button like in 1:04-1:09 in the video. Which normal working phone turns itself on by simply putting in the battery...?
So it must get a command for turning on - (possibly through a defect power button?)
@Virnik0, do you remember, if you could hear the micro-switch clicking on your phone before replacing the button on the mainboard?

Your power button is faulty, replace it before you try fixing anything else.
Thank you very, very much for helping! :good: :good: :good:
Truly the power button was fault although you could hear clearly the "click".
I unsoldered and removed the power module and (by startig with JIG and rebooting via ADB) the phone works as it should. :victory:
Now I'm trying to solder a new power button......it's a bit tricky
Again, thank you very much guys!
I had the same problem, pressed the button many times, and it helped. Thank you for your suggestions
