Hello all. Forgive my newness, but I was an iOS person who just recently started working with an Android tablet.
My Viewsonic gTablet was not running very fast on Android 2.2, so I decided to upgrade it to Honeycomb (or at least to Gingerbread). I downloaded CWM8 for the gTab, and followed all instructions. I powered it on, used my volume keys to select the CWM file, and left it to sit for the appropriate length of time. Unfortunately, the installation failed to go through. Soon after, I started having problems with apps crashing as soon as they were opened, and having to be forced closed. I decided to go back to factory specs, and started that process. When it restarted the tablet, it came up to the three-birds screen, and a message in the top left says Booting recovery kernel image. It then just stays there, and does nothing. It doesn't seem to matter whether I power up with the volume key pressed or not - either way I get the same message. Manipulating the volume keys doesn't seem to do anything. Once I left it like that for ten hours while I was at work, thinking maybe it was just slow, but there was no change.
Following instructions from AndroidZoom, I loaded a recovery file onto an external SD card, to see if would boot from there. No luck. Still stuck on the booting message, with no option to select anything from the external card. Now for the million dollar (or at least $200) question:
Is there a way to access the tablet's internal SD card from my PC even though the tablet won't boot? I figure if I can, I will delete the new recovery file, and load a replacement file from viewsonic which I was lucky enough to find on the web.

I hope I have this in the correct area.
I am running a stock unit with Market and Rothnic enhancement pack. I have not gotten an over the air update since just before Christmas. I finally decided to upgrade to the 4349 software that was posted here. I placed my recovery folder with the command line in it and the update.zip file on my sdcard (internal). Booted up with the vol + and power key and it started to upload correctly. When it tried to reboot on it's own, it hung on the "n" screen for over 45 minutes. I manually shut it down. Retried to start it and nothing. Now, if I let it go normally it gets hung up at the "n" screen and does not proceed after this. If I try to force it to go to the recovery mode it just sits there with the little messages saying a recovery key was detected.
What can I do to reload my software? It seems like it can't find the operating system? I do have an external memory card. Can that be used to boot the system from?
Any help would be appreciated. Please keep in mind that I am not Android gifted.
I just found a post from butchconner in another area that may help me. I will try to reboot from them memory card. I will let you know if it worked.

You posted this in the wrong section. The Q/A forum section is here:

To answer your question, you need to NVFLASH back to stock. Follow directions found here:
http://forum.xda-developers.com/showthread.php?t=861950
Thank you. I have just tried to reboot from the memory card with out success. I will try the NVFLASH but I am curious how this will work since it will not load from the memory card.
OK I have followed the text. One problem. When I connect the tablet to my PC I hear a ding. I go to my device manager and I see a NVIDA tegra 2 device. I do not have any APX listings and no exclaimantion points. When I run the nvflash program it says USB device not found Press enter to continue. I have attempted to update the drive on the Tegra 2 device but it says the drivers already installed are newer than the one I am trying to load and it stops. So what should I try to do now.
Moved to Q&A.
Eureka Success. The instructions were very clear. Unfortunately, I can't read. I completely skipped over the volume down button. That is why I did not have the APX mode. It is downloading 3588 now. Thanks again dzasta for pointing me in the right direction. And special thanks to roebeet for setting up the cheat sheet.
Glad everything worked out. NVFLASH is a great utility when stuff gets real messed up. Saved me a bunch of times and once you have it all setup, its so easy to use.
Hello,
I tried searching but the results all seemed like they were people who have rooted and have alternate ROM's.
I am completely stock with 3588, no clockwork, not rooted, nothing else.
A couple of days ago I turned it on and it went through it's normal routine until it got the point that it should have loaded the home screen. Instead it flashed something for a brief moment and the only thing I caught was 'Android System' in the top left, then it shut down. Prior to this I wasn't having any issues.
Now when I turn it on it shows the birds, then gtablet, then the tap'n'tap and peacock but instead of of then loading home screen it goes black for a moment then the tap'n'tap comes up again. It will do this 4 or 5 times then simply goes black.
I connect the USB to my PC but of course I can't access the tablet.
I opened it up and tried using the reset button, no help.
Disconnected the battery for a minute, no help.
So no clockwork or nvflash, can't copy files to it. Am I boned? Any suggestions on what I might try?
Thanks for any suggestions,
Neudle
Try a data wipe using Method I from this: http://forum.xda-developers.com/showthread.php?t=1030915
It will delete any apps you've downloaded and installed but it just might get you going again.
Up and running.
First off thank you very much for that help. The tablet is working again.
I didn't realize it would run a recovery from sdcard2 without the command file pointing to it specifically. I thought it only defaulted to the internal sdcard.
Does anyone have any idea how or why this might have happened and any advice on how I might avoid it in the future?
Thank you again,
Neudle
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
Paul

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 a TF201 that I don't know the history on. It turns on to gears and a red triangle exclamation. The weird thing is if I tilt it, half of the screen shows android start and setup.
I figured I could find the stock rom and flash it using MicroSD, however looking everywhere I can't find a true stock rom. I can find stock roms that are modified to unlocked devices, but not true stock.
When I try to do a wipe, it says 9.4.2.7 at the top I noticed. I don't know if that helps.
Suggestions?
EDIT:
Good source for firmware
http://forum.xda-developers.com/showthread.php?t=1429873
So I found them on ASUS's site. I had no idea they were under Android on there.
However, I can't get adb to find a device on the computer because I only have two icons holding volume and power (Wipe Data, Android).
If I put a SDcard in the tablet like on a TF300T and go into RCK, it doesn't work. Android goes belly up with red triangle. Is it the name i'm using? I tried update.zip, the stock firmware name, and EP201_768_SDUPDATE like I use on the TF300T.
Also, when it's hooked up and I type fastboot device, all I get is waiting for device.
I don't know if this is because it needs to be in a debug USB mode, but I can't get there to check. It does recognize the tab on the computer when I plug it in though.
Ok, so I fixed it.
I downloaded US_epaduser9_4_2_7Updatelauncher.zip
I then put it on a MicroSD card formatted Fat32 and renamed it EP201_SDUPDATE
Then I put it in the tablet and held volume down and power until it prompted to go into RCK and no more dead android, it took and loaded.
EDIT:
DIDN'T WORK (
It loaded like it was going to work, but I am back to the gears and the red triangle.
FUUUUU.JPG
haha, I feel like I am in here by myself. However, I want to document all of this in case somebody else runs into the problem I ran into and they're a rook too.
I fixed it. I wasn't sure what ROM was originally on it and when holding volume and power I noticed the 9.4.2.7 so I assumed that was it. However, I tried that ROM and it seemed like it was going to work but kicked the gear and triangle.
I then figured what the heck and tried the newest rom I could find. The 10.4.2.18?? I think it was. Whatever is the newest on the link I put in the first post.
It ran, and rebooted and Wahla, worked.
It's important to note my directions of FAT32 and the EP201_SDUPDATE as it took me a while to realize those had to be in place properly for the MicroSD card update to work.
I have the GT-S7560M through Solo (Bell) and I rooted it shortly after purchase last year. I've been happy with the phone and for the last few weeks an upgrade notice has been appearing but would fail when applied. Some searching suggested the root was interfering. At first I started to look into un-rooting the phone, but then thought that a factory reset would be the simplest, least-risky solution. I had done a factory reset on my last Galaxy phone without a problem so it seemed like a safe choice. I backed up the contact info, etc with Kies (I don't use many apps so I didn't go all out ie Titanium Backup) and removed my SD card.
Now the phone boots to screen asking me to pick a language and press Start. Then it moves on to a black screen with the info bar at the top (clock, cell strength, data xfer) and nothing else. It is auto-rotating. The phone does react to touches with the buttons lighting up, but I can't get anywhere. Kies can see the phone, the phone number, the firmware version and all that. It reports Internal Memory as 84.83MB used of 1.58GB. I can navigate through the phone using Windows Explorer. I did a Restore with Kies but it doesn't seem to have had any relevant effect.
I am able to boot into CWM Recovery. I don't remember doing a back-up with it, and when I ask it to restore from either the SD card or the interal SD it says it can't mount.
At this point I would start thinking about taking the phone back to the store, but a flash counter appears during start-up and I'd rather they didn't see that for obvious reasons.
When I google I just get people who have bricked their phones. I just want my phone to work again. I'm not worried about modifying it further to achieve that.

I've just finished doing that, and it appears to have worked.
For anyone else with a similar problem who finds this thread:
- Go to the FAQ here: http://forum.xda-developers.com/showthread.php?p=45767157#post45767157
- Download Daver18qc's root kit at the link provided (you'll have to scroll down to the second post). You want this to get Odin; don't worry about the zip's other contents.
- Go here: http://www.sammobile.com/ and register. It's free and all it wants is an e-mail and your country.
- Go here: http://www.sammobile.com/firmwares/ and type s7560m in the search box. The list will automatically update. I'm a Solo customer and chose 'Canada (Bell Mobile)'. When I first tried this in Firefox I would get a screen telling me I wasn't logged in. I tried it in IE (which I never use and so is 'clean') and the download went through.
- Go back to the FAQ http://forum.xda-developers.com/showthread.php?p=45767157#post45767157 and scroll down to 'Short Tutorials' and 'How to Flash with Odin:'.
- One thing it leaves out is that when you boot into Download Mode, you will first get a warning screen that asks you to either press Volume Up to continue or Volume Down to abort and reboot. Not a big deal but it caught me off guard. Odin will not detect the phone until you get past this screen.
- Continue with the Tutorial. After it is done you will have to setup the phone again. But at least it's working now.
