Hi everyone,
I just bought a TF201 with the latest update from Asus (end of past year).
As I discovered Android 4.2 has multi user support, I wanted to install it.
So, first, I unlocked the TF201 with Asus Tool => On boot screen, I can now see a white message saying something like "The device is unlocked"
Second, I used MotoChopper to root the tablet and create superusr directories.
At this step, all was fine. I was sure that the hardest was behind me.
I downloaded ROM MANAGER (Clockworkmod) on Google Play then I clicked on something like "Recovery" which asked me to reboot. I don't remember the manipulation as I was sure nothing bad could happen from a Google Play app with a so good notation.
The table never rebooted.
I stay on the Asus&nVidia Logo boot screen.
I can't turn the tablet on. Each time I try, it reboots automatically...
I can't enter recovery menu with Volume - (nothing happens at all)
The tablet isn't recognized in Windows anymore
But... if I boot with Volume +, the tablet screen keeps black (no logos) and Windows detects it as an APX device.
So, I installed naked drivers and now, Windows see an Asus Transformer Prime APX interface.
That's all for now. I don't know what to do.
Does anyone have a clue ?

Sorry to be the one to tell you but I was in exactly the same situation as you (http://forum.xda-developers.com/showthread.php?t=2304071) and after much research it seems that unless you have backed up using NV Flash you're out of luck

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?

CWM is not installed
flash the latest firmware using stock recovery

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.
Jim
Looks like Brian and I crossposted each other .
For the recovery/command file on the external SDCARD, put the following text in it:
--update_package=SDCARD2:/update.zip
NOTE THE 2 DASHES AT BEGINNING OF THE LINE...

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.
Ok, so first off, thanks to everyone here for all the info that I've already used. Here's hoping you can help get me the rest of the way. My problem is that, regardless of whether I boot simply (just power) or to clockwork (power and +), it always displays the three birds, says "booting recovery kernel image", and then goes nowhere. Here's how I got there.
I just got my gtablet new less than a week ago, and tried following the directions on here to get VEGAn-tab v5.1. Somewhere on my first attempt I messed up, so I used nvflash to wipe everything and start over, following again the instructions on xda. The version of nvflash I used include clockwork mod, if that matters.
So here I'm booting successfully to clockwork, and follow all the steps to install VEGAn-tab. Except, when I rebooted, it always booted me back to clockwork instead of VEGAn, including when I booted with just the power button. And I had no idea why. I left the unit alone for awhile to ponder things.
This afternoon I decide to try and nvflash once more, in case I did something out of order. Turns out that now when I try and enter APX mode (power and -) my computer (Vista) isn't recognizing it (I do get that little connection sound, but no pop-up / identifier in the directory). And yes, when the tablet is connected in APX mode, my driver is installed and looks fine.
What is going on here? Hopefully someone will have some fun trying to figure this one out. Help xda-kenobi, you're my only hope.
I am a noob but I just used nvflash on my tablet yesterday and if I remember correctly you aren't supposed to get a pop up when you boot your tablet in apx mode and connect it to your pc. Your computer will make the connection sound and all you have to do afterwards is open the nvflash folder and double click on the nvflash_gtablet.bat file. I think the only time you actually get a pop up when you connect your tablet to the pc in apx mode is when you do it for the first time and windows tries to look for the driver. Hope that helps you out.
Yeah but...
Yeah, I wouldn't necessarily think that I'd need formal recognition, but when I try to run the .bat file in APX mode subsequently, it tells me that "nvflash configuration file error: file not found" which makes me think it really can't find it for some reason.
uses nflash ..
http://viewsonic-gtablet-for-dummies.webs.com/
refer this thing first. I think u did the (installing wrong version of rom for your bootloader kind of mistake)
Assuming that you installed the driver => (check nvflash section about how to install driver), i might want to remind you that apx mode looks blank , u can't tell the difference. But once you run nvflash you should see a line in the tablet in apx mode
Check the site I told you, everything (the stuck in birds thing) is there
Btw, if you happen to able to recover, I would advise you to install Vegan Tab 7.10 by gojimi, it's the stable and updated version of vegan 5.11
Thanks! And watch out for McAfee
Heyall, thanks for the advice pointing back to the dummies site. I cleared all my previous downloads, started from scratch, and have vegantab 7.1 loading now.
One note for others out there having trouble with their computer recognizing the tablet in APX mode - I think my anti-virus (McAfee, don't blame me, it came free from work) was blocking the tablet from linking up. I've had the problem before with McAfee where it'll allow something to link the first time (usually with an online game) but then later will block it, asking for permission.
Anyways, if you're ever in the Ft. Worth area, I owe you a beer. Thanks again
This is old, but I had the same problem and found it in a search. It worked so I wanted to say thanks!
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:
http://i.stack.imgur.com/kcSE4.jpg
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.
Hello everyone,
I'm a bit crying right now, i hope you can help :-/
So, i thought about going to cyanogen on my tf201 some months ago. What i remember is that i unlocked it using the asus software then i installed some versions of twrp (i think). After that i stopped because i was kind of lost between many tutorials.
I did not use the tablet since that, i was abroad.
I get it back today and i tried to reset everything, so i went in the settings and click on the reset thing. It did not work, the tablet just blocked on Asus screen and when i manually restarted it, it was like i did nothing (normal boot and no reset).
So i went in the bootloader (power + vol down) and i tried the (4th?) option to wipe everything. The thing said something like "loading image ...." and blocked.
Now the tablet is blocked on the first screen (with asus writen in the middle) and it won't boot, i can not go into the bootloader either, i only have that screen.
I can not even shut it down, keeping power pressed will only restart it.
Is there anything i can do or is the tablet dead ?
Thanks for any help
Hello, I have a tablet sitting in front of me that I need to repair. The tablet will only boot to a screen that shows a usb logo and a white bar, which eventually changes to red. It appears that the device doesn't have a working bootloader and will only go into what seems like a download mode. Connecting the device to the computer shows "CLOVERVIEW" in device manager. Attempting button combinations doesn't provide any results. I do not know how to proceed from here. Any ideas?
This video seems like what I'd need to fix it (Intel manufacturing flash tool), although I don't exactly know how to apply this to my device.

EDIT: Fixed it and did a write-up: http://forum.xda-developers.com/memo-pad-7/general/howto-unbrick-hardbricked-memo-pad-t3105945
However, I managed to get myself stuck at the ASUS splashscreen. Does anyone know of a way to get past the splashscreen or force download mode on a MeMo pad?
