So I flashed my Trio Stealth pro 7" Tablet, which is a knock-off of the Ly-f1 tablet. I apparently used the wrong .img, because on the first boot up, the touchscreen does not respond at all. The screen displays a "Encryption Unsuccessful" error, and asks me to do a factory reset. Holding down the volume button and then powering on the tablet displays a black screen with nothing on it. Upon trying to connect it via USB to my computer, it is not recognized, and I'm not able to find the Drivers for my device. I now have the proper .img file, but I'm not able to get into recovery to flash it. How would I do that?
Thanks.

My Tf got stuck at the logo Eee Pad boot after I tried to restore the old rom, and now it can't do anything except boot and stuck at the logo.
I tried the nvflash unbricking technique from rayman84 : http://forum.xda-developers.com/showthread.php?t=1123429
, but my TF only listed as unknown device when I tried to get to APX mode and it also said,
"This device is disabled because the firmware of the device did not give it the required resources. (Code 29)"
Now I don't know what else to do. Please help! I hope I am not completely bricked the device yet.
Have you tried the button combo to get into recovery?
Press and hold the Vol down + power button.
When prompt, you'll see lines of words at the top left of the screen, push the Vol up button immediately within 5 sec to get into recovery.
Apparently, I didn't know the button combo. Anyways you save my niece's TF. Thanks a bunch
Edit: although the tablet is working now, it still got the message usb unknown device. Do you know how to fix it?
Hi, i don't know if i should post a new thread but my problem is almost the same as bengob3t's one.
I have a brand new TF101 with a B70 Serial number, but i successfully rooted it using the RazorClaw Tool. Then i tried to install clockwork mod followin this topic : http://forum.xda-developers.com/showthread.php?t=1106587
I directly applied the instructions from step 8 (download hashmyfiles etc...) and i rebooted my Eee pad manually step 13
I didn't see any progress bar, but my device is stuck on the Asus screen, and the speakers make stange noises at regular intervals.
I am able to go into recovery though (power + vol down then vol up) but the factory reset doesn't work, and i cant really do anything (at least not anything that i know what it is).
Is my tablet definitely bricked ? If not, how can i bring it back to life ?
I wasn't able to use NVFlash, as i can't seem to go in APX mode. I press power+vol up, i hear the sound usb device connected and immediately after i hear the sound "usb device disconncted"
Nvflash says
"Nvflash started
rcm version 0X4
Command send failed (usb write failed)"
Thanks in advance for your help.
EDIT : When i put the micro sdcard from my phone into the tablet, i am able to mount it. So i will probably be able to flash something from it, but what ? Do i have to flash a recovery ? Directly a custom rom ?
I'm a little lost, but i'll try to give you guys as mush info as i can find.
EDIT2 : I flashed the PRIME rom, everything seems to be back to normal... if you got info on my situation, don't hesitate to fill me in ^^ i'd like to understand what i did wrong, even though i dodged the bullet.

Do you have the correct driver installed? Do you have Asus sync install on your PC?
hmm.. I'm not sure. I downloaded the unbricked tool nvflash file, and the tool already had usb driver inside it. Is that the driver you were talking about? I never were able to get to the point where I need to point the APX to where the driver located because it always said unknown driver the whole time.
I just bought an LG V905 tablet used but there is a password on it.
I can't get it to do a factory reset.
I tried holding the volume button ( both up and down ) with the reset button.
when i use the up volume button i get a screen that says "entering lg mdp mode"
and "DO NOT POWER DOWN" downloading now..."
i left it over night like that and it still was at the same screen in the morning.
when i try it with the down volumne it get
"Starting fastboot usb download protocol" anf the LG logo and it sits there.
can anybody tell me how to reset this tablet ?
Thanks In Advance

I'm in the same boat.
I had a force close happen while installing a 3d wallpaper apk that rendered my touch screen insensitive to touch. This virtually bricks my device as I cannot unlock the screen during start up. Everything else works as I can hear notifications and watch it connect to my wifi network.
I've tried flashing stock images for the lg-909 (system.img, bootloader.bin, flashboot.img) and this did not work on my LG-905. It would get stuck in a continuous boot loop in the t-mobile animations.
My LG-905 is a Rogers device so the stock images are now obviously different than the T-Mobile's.
I need fresh images for the LG-905. If anyone has rooted their device using the instructions for the LG-909 they will have one of these back-up images available. I would ask someone help me out by making this available to me. Mine has been corrupted and is unusable.
Other than this, perhaps someone can help me restore my screen sensitivity by some other means as I have access to the file system using ADB, APX and sometimes fastboot (when it works).
I have an allwinner a10 (looks like this http://www.made-in-china.com/showro...ch-Allwinner-A10-Tablet-Android4-0-M727-.html). I wanted to use cyanogen mod, so managed to get adb working, and cwm. Then tried to install the cema rom from here (can't remember why, but I convinced myself it was the right one):
http://forum.xda-developers.com/showthread.php?t=1821398
The device still turns on, I can access it through adb and eclipse and I can hear it connecting to the PC. However the screen backlight comes on but doesn't display anything. I can reboot the tablet through adb, but still nothing on the screen. If I try to boot into CWM by rebooting whilst pressing the volume up button I get nothing on the screen.
It's hard to give anymore specs on the tablet as I can't view anything on the screen to report! I don't know if there's a way to get specs through adb?
Is this saveable?
Many thanks
Hello everyone,
some days ago I flashed Android Revolution HD but shortly I've found out that the TF101 wasn't recognized anymore by my PCs. When I've inserted the stock cable the tablet turned on but nor win 8.1 64bit nor windows 7 64bit recognized it. It even hasn't appeared between the unknown devices in the related window, so I couldn't install any drivers. Then I've decided to clean cache and system on TWRP recovery and after reboot the TF101 was stuck on logo screen, the boot one, not the next one with the ASUS logo.
Now the stock cable and the stock charger still work, they charge the tablet but the charging screen doesn't appear, if I turn on the device, it shows only the first android logo with the green bar, if I try to enter recovery with volume down button, it says 'entering the recovering' but it doesn't go any further. Last chance is the APX mode, with the volume up and turn on button: I've tried it but I can't recognize if it enters APX or not, I only know that in the devices list doesn't appear any unknown device, and I'm sure that the TF101 has never been connected before to this PC. At least, if I was able to connected it in APX I would use Easyflasher and flash stock rom.
Basically now it's a bricked tablet, any help please? Someon can tell me specifically how to enter APX mode, or is it a cable issue? Is this thing called 'governor' related to this?
I received an Acer A700 from friend and here is the story;
He started getting the boot loop issue, Acer logo and reboot, etc...
He got into factory reset mode, and attempted a factory reset, during the process, it froze on "formating" and he attempted to shutdown the tablet. After he shut down, the tablet no longer does anything! Power LED only comes on during charging, and no beeps, no vibrate, no screen, just black. I have tried to use the usb connector to connect to my PC, but the device shows up as an APX device, but drivers fail to load, and then the device disappears. I have tried to install the latest usb driver from Acer, but no luck. I have the same tablet and I use CM and would like to get him moved over to that if possible! Any one has any suggestions, or is he bricked?
Thanks

If he's booting in APX mode, (black screen, PWR lite on, and seeing it shows up as an APX device), he's pretty well bricked. Problem is, it takes NVFlash to flash the proper files in that mode, and unfortunately also and SBK (Secure Bootloader Key) which Acer refuses to give us.
He can try doing a manual data erase (there's a post sticky on key combinations in the forums that explain how. )
If he can get it into fastboot somehow, it's possible to erase some of the partitions. Might help.
Heres the link for some manual modes. Note that some of them changed from ICS to JB, so might help to read all the posts. If he can get to fastboot, it would help a little.
