same thing

Noticed when attempting the cwm fixes tab showed Viewsonic screen for a second but then rebooted with just the Gtab screen. Turn it off and back to the same thing...

Yes it goes straight to Gtablet logo
[G Tablet Q&A, Help & Troubleshooting] johnseidel:
Citi,

I am having identical problems and frustrations. Tried everything you have, as you and rbansal2, and gone down this tortuous path. Please keep as much of your discussion public as possible, or, if you can, please PM me.

thanks

John
[G Tablet Q&A, Help & Troubleshooting] Citi:
Dont worry when a solution comes along that works for me I will type up a guide. But until then we haven't really made much progress at all, rbansal is currently attempting to recreate the issue, with no success.
[G Tablet Q&A, Help & Troubleshooting] johnseidel:
The abscence of the bird screen when the NvFlash is applied might be a clue.

I'd volunteer time and energy but I have an obligation tonight and have to let this rest. And I am going out of town tomorrow afternoon for the weekend. I will try to keep up as best I can.
[G Tablet Q&A, Help & Troubleshooting] Citi:
I am on the verge of announcing a reward for whoever could fix this..for now I guess it's a permanent brick. I have searched these forums for the past few days nonstop with no luck. Seems as if my tablet is unique and the fixes that have worked for others are very unsuccessful for me.

Tablet will not Turn On - APX Mode - NV Flash

I decided to revert to stock ROM after troubles with wifi adhoc and USB connections using a MOD ROM. I was even more motivated by the OTA update on 4/17/2011.

I used the NVFLASH with Roebeet's update to a 3588 build. It failed. I got stock in the APX - bootloop will not turn on mode. Reading and reading I read about using NVFLASH 151kb in lieu of 139kb versions. That seemed to help. I also went to the 1105 version of the original. For some reason I tried to toggle APX and got the birds, when I got the birds I switched from Vol- to Vol+ that actually started a boot loop that would go to a black screen. But, I could do that now without using NVFLASH.

Reading further I was able to push the CWMOD image into partition 9 per the thread above. When I got CWMOD to load I went through the steps to start loading a mod rom and set up to load the 3389 build which is what my original unit came with as stock.

Now I can power on/off and start the enhancement portion and OTA updates for my unit. Hope this helps.

Gotta say the forum users are awesome with their Tips and Tricks and the Developers are well how's that go "Next after God" Thanks.
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
Are you familiar at all with ADB?
[G Tablet Q&A, Help & Troubleshooting] johnseidel:
There is something in common between my tablet and yours, and apparently a few others. I spent yesterday and today doing almost all the things that you did. I had great hopes when I discovered this thread. I have come to the conclusion that we are looking in the wrong places.

There is something that we are missing? I am going to review the problems and the failed solutions over the next few days. Start systematically documenting and looking for potential suspects or problem areas.

I'm not ready to give up. But my family owns most of my time for the next five days. So I'm going to allow myself to be distracted for a while. Then I'm coming back to this problem and figure out why we are in this black hole and how we can get out of it.

Besides, I'm in deep trouble here. The bricked tablet is my wife's. She's not a happy camper now, especially when she see's my tablet running Vegan Gingerbread.
[G Tablet Q&A, Help & Troubleshooting] JoeMofknDot:
citi have you tried the flashing internal cw.08 via nvflash without a removable sd card installed.
[G Tablet Q&A, Help & Troubleshooting] Citi:
I want to say no because I was familiar with NVFlash and that completely bombed my system, so I guess I wasn't familiar enough.

Yes many times, I can get into CWM. I have repartitioned, I have wiped, I have done it all with no success.. Permanent APX continues
[G Tablet Q&A, Help & Troubleshooting] JoeMofknDot:
are you on the irc now
[G Tablet Q&A, Help & Troubleshooting] cyberpyr8:
Sorry to hear the one you bricked is your wife's!

I think that somehow one of the partitions got corrupted or erased and that the NVFlash process cannot rebuild it. My NVFlash doesn't error out and the system boots, albeit without the Viewsonic logo showing up. I think that because that isn't working it is bypassing the CMW startup. When you try and reboot it cannot load that partition and therefore won't boot. /SherlockHomes :)

I have used ADB before but I cannot seem to get it to connect to the tablet. I was hoping to be able to reboot recovery mode that way. No luck so far.
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
I too am stuck in this loop as well now. It's like my tablet is in permanent groundhog day. Anything new since last night?

edit:

Also, should I be able to power + "-" volume button (I'll just call it "P-") to get it to no longer be in apx mode? I've noticed that with the device off (or at least appears to be), when I do the P- I get the new device noise from the pc and it shows up in the listed devices. When I P- again, it disconnects.

Weird thing is the exact same behavior (pc "new device" sound, plus listing in devices) seems to occur if I just to the power button alone, as well as the power button and + volume button (P+). This continues when I do the action a second time, in that the device disconnects.

So, until someone tells me differently, I'm guessing that I now can only boot up in APX mode, despite whatever button combination is used. Maybe this will help... Anyone know, in very dumbed down language, how I might reset the button actions?

Thanks
[G Tablet Q&A, Help & Troubleshooting] cyberpyr8:
I have noticed when I have the USB cable hooked up and I hit just the power it sounds like the device is powering off. So you have APX and off only. I am seeing more and more posts with this same problem. I would advise against doing an NVFlash right now unless you are bricked until someone can fix this.
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
What's the activity that NVFlash is used to seeing as far as updates/ bug fixes? At this point I'd be fine hitting a red button on the thing and starting the whole process over if that was an option :)

Thanks

Tablet will not Turn On.

I was stuck in this same mode until I found the thread about NVFLASH having two different versions. One application is 151 KB the other is 139 KB. the thread posted a zip file listed as rev 2. It talked about the fact that Partition 2 is the critical partition for recovery.

So I checked roebeet's file and found that it is using the 139KB application file. I deleted that and pasted the 151 KB into my NVFlash Directory. I installed the original G Tablet image files - not the 4/19/2011 update version. I flashed that to the system. It went to Boot cycle. when the screen went blank. I went back to try and toggle out of APX mode by pushing power & vol+. I got a screen to come up but no effect so I toggled power & vol-. At this point I saw viewsonic birds. This was a small step but not complete. However, it gave me hope.

This is when I flashed partition 9 with the CWMod image. At this point I was able to toggle into a recovery mode. (I've forgotten how but, I pushed the 3389 ROM either from the USB drive or a microsd card and triggered an update with the recovery command. At this point I had a working gTablet again. This morning I pushed the update to 3588.

I hope this helps. If there is a detail missing the respective threads probably have it. I don't have time to find those right now.
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
Anyone know where I can go to get the 151 KB file, plus the original Gtablet files? Out of the long library of files I've now amassed I've probably already got it, but I no longer am in the mood to assume anything... Thanks!

Though I just tried it on 2 PC's and it crashes at the end and doesn't seem to be finishing the process.
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
Pulling down now. Was it failing for you on dl or when trying to use?
[G Tablet Q&A, Help & Troubleshooting] cyberpyr8:
After the last file is flashed it crashes in Windows. I have tried running manually from an admin command prompt as well. It doesn't like something at the end for me and crashes. It doesn't reboot the device and then I am stuck manually rebooting it and that doesn't work.
[G Tablet Q&A, Help & Troubleshooting] cyberpyr8:
From Roebeet:

That doesn't sound encouraging! :( I will try the erase
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
So are you saying you can't boot up at all now?
[G Tablet Q&A, Help & Troubleshooting] cyberpyr8:
No I can still NVFlash with the 139kb file and get it back to where it was. I just tried the format_all switch on it and the app crashes so it is a no go for me.
[G Tablet Q&A, Help & Troubleshooting] cyberpyr8:
Just tried the verify all partitions and it said:

ERROR: Partition with Id 0 does not exist.

ERROR: Verify partition arguments check failed: 0
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
Yeh, my flashing bombed out too. I'm gonna rerun and see if I can determine which file it's on. I suppose if it's one of the replaced, perhaps I could regress it to the old on.

So mine seems to fail right after the line "11_App.img" sent successfully.

Poking around in the files (since I don't actually know what I'm looking for) I looked in the cfg file and found a sequence that appears similar to what I see happen in the cmd prompt. After "11_App.img" comes the following block:

[partition]

name=CAC

id=12

type=data

allocation_policy=sequential

filesystem_type=yaffs2

size=0xFFFFFFFFFFFFFFFF

file_system_attribute=0

partition_attribute=0

allocation_attribute=0x10

percent_reserved=0

Also, this is the last block.

Comparing both the configuration files and bat files from both, the commands inside are identical.
[G Tablet Q&A, Help & Troubleshooting] Citi:
I assume there is no way I can return this now? The irony is I was hoping to return the tablet to stock and return it to VS due to a dead pixel

Edit* It was bought from woot, so the only chance of return would be warranty with VS which is voided I assume...
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
so switching out the files one by one, and even editing the config file to try to take care of the last block using the smaller nvflash.exe didn't work

sd: I thought I was doing pretty well at keeping my source files in both flash directories untouched and doing everything in a sandbox folder, but somehow I ended up causing both batch files to error immediately upon running... don't know if there was corruption or something else, but a reboot and re-extraction of the files seemed to get things going again

now, things seem to be a little different- while I continue to be unable to not boot up in APX mode (as in can't turn it off), which also means I have to flash just to get to the default os, the newer flash that was failing for both of us at that last block now exhibits a different behavior. Upon running it now, I get something entirely different that just seems to stall... image is attached.

later add-on:

since it's been over 20 minutes since cmd prompt got to the point in the screenshot, I powered down the tablet, at which point cmd prompt spit out

"command failure: bootloader download failed

Press enter to continue:"

...so I guess it was still at least pretending to be doing something
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
If any of you would like to put your malfunctioning tablet in my hands for a day or two so I can pull some diagnostic info I will do everything possible to get it working again. Any of you in/near the Florida panhandle?

In the south, but not close enough... Anything you can walk me through that I could pull and send you?

[G Tablet Q&A, Help & Troubleshooting] Leachpunk:
I was experiencing some of the same similar problems as Citi up till a bit ago.

I now have 3588 booting and rebooting correctly with screen able to go to sleep and wake up again.

I used the 1105 nvflash with the rom boot. Did everything as another poster stated earlier. I set my display to never timeout. I downloaded the update making sure that it completed, and rebooted when asked. It reinstalled and I saw the Viewsonic logo again for the first time in a while after being in the APX loop.

Now if only I could successfully flash a rom.
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
Yes... everything ;-) I have no idea what to ask for since we really don't know what we're looking for at this point. It would be nice to see the partition tables, logs, debug reports, etc. but mostly I want to actually have the machine in my hands so I can control everything that happens to it during the process to make sure nothing is overlooked.
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
Congrats! Here's something to consider... If you ever want to try a different ROM start from the most basic configuration you can. Clear cache, wipe data, flash to a known good configuration before you start (I even repartition just before installing anything experimental). But most importantly... if you have trouble DO NOT use the shotgun, try anything method to troubleshoot it. Many of the folks I've helped have done themselves more harm than good by trying the most invasive procedures first. The basics will fix most issues. Clear Cache and wipe data before you try resort to partitioning and nvflashing. and do one thing at a time and check the symptoms to make sure they're the same.

Doesn't hurt to ask questions and have someone walk through it with you either. Best of luck to you!
[G Tablet Q&A, Help & Troubleshooting] CodeNamePapa:
This is something I wasn't able to fully complete the other night, I didn't set the screen to stay on, but I kept tapping it to keep it awake. the download failed when it was halfway-ish complete.

(of course, I was pulling down huge files to try other recovery options, so perhaps the tablet didn't like sharing my bandwidth...)

I will add "get 3588 OTA installed!" to my list of stuff to try...
[G Tablet Q&A, Help & Troubleshooting] Citi:
I've already set my display to never timeout and have downloaded the update however upon restart it goes back to APX.

Anything you do differently? My optimism has taken a steep decline due to this issue :(
[G Tablet Q&A, Help & Troubleshooting] CodeNamePapa:
This method worked for me...

Citi, I can't recommend highly enough K J Rad's method he posted here

http://xdaforums.com/showthread.php?t=1030915

Method 1 worked for me - in 20 minutes I went from days of apx boot loop drama (and failure) to the stock 3588 that actually reboots to the ROM and NOT APX MODE.... after days of searching threads, and 10x or more nvflashes, geez.

and my lengthy "hey it worked" post here

http://xdaforums.com/showpost.php?p=13077016&postcount=23

EDIT: FWIW - I never got the 3588 OTA update to complete when I nvflashed and booted to stock - it would download about halfway and bomb out.
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
Going to give this a try...your matter-of-fact tone gives me some hope, which is good as I've kind of lost most of mine in the last two days.
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
After reading through the linked thread, I'm unsure as to whether I'd be able to complete the sequence. I've pm'd K J Rad about this, but I'll put it here too - Since booting up in recovery mode is part of both method options, is it safe to say that if I can't currently boot into recovery mode that I won't be able to then, at the point when it's time to? Or do the steps that come prior to the recovery mode boot up fix my inability to do so? Thanks for any help
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
Look at it this way... if it doesn't boot into recovery... then it can't possibly cause you any more harm ;-) Seriously, this method is a complete waste of time if the tablet will not enter recovery mode. But you have nothing to lose by trying it to see. If more people would try less invasive procedures like this before they reach for nvflash or repartitioning right away it might save them all this headache. Many problems can be cleared with a simple data wipe.
[G Tablet Q&A, Help & Troubleshooting] CodeNamePapa:
aeneas_shrike & K J Rad -

All my nvflashing never resulted in being able to:

- restart the tablet w/o jumping into apx

- restart into recovery via the "recovery.img swap with part9.img" technique

I was skeptical that --wipe_data would be a fix-all but it sure was.

Again, I'm dealing with a weakened brain due to sleepiness so I apologize for not having a firm answer on what EXACT steps I did. I had the command file in place on the microSD and either:

- fired up to recovery (power & volume.plus) and saw Recovery Key Detected and BIRDS

or

- had the microSD card loaded and held down volume.plus as an nvflash finished, and then saw "Recovery Key Detected" when it rebooted.

like K J Rad said - it won't hurt to try.

But, I must point out - recovery DID work (clearly) but what wasn't working was stock recovery loading an update.zip, or trying to install Clockwork while still dealing w/ the apx boot loop.

before I tried K J Rad's --wipe_data I decided to try loading clockwork's update.zip and the recovery folder & command file to the microSD and then firing up Power & volume.plus - this failed.

but, recovery ended up working - just not like I had been trying before - a command file with --wipe_data was "read and loaded" when the clockwork update.zip method was completely ignored.
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
I can't argue with that. Initially after running into issues, I was trying anything and everything, just so I could get my one day-old device on something other than stock. After getting stuck in the recovery boot loop, the next suggestion I ran across was flash, so like a monkey that's what I did next unfortunately. I've slowed down since, but I'm still hopeful that something will come along.

I'll give the above sequence a try and report back.

Thanks

I think these links described the issue and solution.
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
Went through both methods. Both times, couldn't boot up in recovery mode - I continue to only boot up in APX mode. Moving on.
[G Tablet Q&A, Help & Troubleshooting] Citi:
Those were both unsuccessful as well, as stated on page one :)
[G Tablet Q&A, Help & Troubleshooting] Citi:
Anyone found any luck towards this issue?
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
Perhaps. We just got through working on aeneas_shrike's tablet and he is now up and running. Here's what we did...

1) Formatted the Cache partition from nvflash

2) reboot

3) nvflashed bekit's 2010110500 stock image

4) reboot

Assuming that you have already nvflashed with that or a compatible image the command for formatting the cache partition is:

nvflash --bl bootloader.bin --format_partition 12

I believe the process could likely be shortened by inserting the "--format_partition 12" (or possibly "--format_all") into the command line in the windows batch file or linux script that flashes the image but I haven't actually tried that.

aeneas_shrike had multiple problems that led to the APX looping condition and yours may or may not be similar. However, this procedure should take the tablet back to a known good "from the factory" condition. If you choose to use some other image or procedure then YMMV.
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
Before I forget... Two last things when the tablet comes back up.

1) Factory Data Wipe. This should clean out any remaining sludge.

2) Re-Partition internal memory 2048 and 0. Many of you won't need this but some will. If you start having trouble again soon... this is your fix.

And there are no dumb questions when you're trying to improve yourself. Besides... how do you know I wasn't googling for the answers...? ;-)
[G Tablet Q&A, Help & Troubleshooting] aeneas_shrike:
what's your preferred method for doing your second item - the repartioning?
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
ClockworkMod is the only method appropriate for most users. I do mine via command line but that is far too complicated for the average user. I am looking into alternative methods.

Citi,

I'm going to try to craft a special image for you to try. I'll contact you tomorrow with details.
[G Tablet Q&A, Help & Troubleshooting] Citi:
Ok, thank you. I have tried everything under the sun at this point.

I was thinking of contacting VS and claiming that after being instructed to go to XDA from there customer service reps for an update, my tablet will not turn on. However, that is a last resort and will involve alot of hassle and stress
[G Tablet Q&A, Help & Troubleshooting] rsfaze:
I was just at this very point, used nvflash and after reboot would get to TnT logo try to load and reboot.

After many nvflash attempts what I did was load clock work recovery update and recovery to my external sd card and flashed them. Once that completed I rebooted into clockwork recovery and did a data wipe, cache wipe and dalvik wipe. Next boot I was able to boot into stock, and from that point I have update all the way to Roebeets latest Brilliant corners.
[G Tablet Q&A, Help & Troubleshooting] Citi:
Unfortunately that didn't work for me
[G Tablet Q&A, Help & Troubleshooting] rsfaze:
were you able to get clockwork flashed or if not where did you hit a problem?
[G Tablet Q&A, Help & Troubleshooting] thebadfrog:
He has what is now referred to as an "APX brick". Something is borked and wont keep the settings on reboot. He has to nvflash on start to get a rom running and cant power off or he has to nvflash again. TCrews was the first known victim of this. Hopefully KJRad or someone will find a fix for this.

And for whover does I think you should have a donate button because even tho I don't have a tab you will save me some IRC headaches and I will donate
[G Tablet Q&A, Help & Troubleshooting] Citi:
^this exactly

CWM can be installed and accessed using NVFlash but it doesn't do much as a data/cache wipe or a repartition has yet to change anything. '

Last I saw TCrews just bought another Tab which if that is the case I would be looking at the Transformer but I will be sure to voice my opinions quite loudly against VS.
[G Tablet Q&A, Help & Troubleshooting] K J Rad:
I've not been feeling very well today but I am still working at it when I can. It would just be considerably easier if I could duplicate the problem.
