Bootloop - TF101G please help

Hi,
i tried to unroot my TF101G with method posted here and it ended with bootloop. I made all steps of instruction (I used Eee Pad Transformer TF101G Firmware: V8.6.6.23 from this site).
I tried wipe data as well. Could anyone please tell me what to do?
Sorry for my English.

You know you're probably the 2nd person I've seen this week with this problems after following that exact thread.
http://forum.xda-developers.com/showthread.php?t=1507322
All you can do at this point is try to put the latest TF101G firmware on your sd card, boot into stock recovery and see if it will flash it.

you mean holding vol down button and then up?
I tried, there is process bar, and then android image with ! sign in it :/

Did you extract the files out of that zip after download?
I think there's an Asus folder than an Update folder after that there's a zip folder inside that. That's the file need to be on the sd card.

tried both in folders and with WW_epad-user-8.6.6.23.zip on root of sd card, neither of those worked .
Any hope Asus service would fix it and won't find out I messed it?
They can void my warranty, I just want my tablet working .
edit:
I fixed it thanks to rayman84 and his Nvflash unbricking tool (http://forum.xda-developers.com/showthread.php?t=1123429)
I was so scared

same problem, but if I start download.bat (Nvflash), the device just disconnects and the bat window collapses. What to do?

Solved
1)Enter recovery
2)connect to PC and install adb driver
3)use "adb push" command to copy a firmware file to PDA
4)install the firmware in recovery
P.s. it's important to update the recovery first of all

Congrats!

[REQ] Tutorial to backup to original firmware

hello i'm trying to original firmware (the last one i can find) but i can't do it with adb or custom recovery maybe i 'm too stupid or french ^^
but if someone can make a thin tutorial , then i can send my tablet to Acer for the screen issue (not solved by the tricks of parameter)
thank a lot

@Amidamaru87,
If you already have CWM installed then it's very easy.
1- Take the original (base) firmware, not the last one. Very likely the last one is not a complete firmware but an update to the original one.
2- Take the update.zip file and unzip it to a folder.
3- Go to folder "\META-INF\com\google\android"
4- Edit the updater-script and put a # as first character of first line. This will avoid this line to execute: #assert(getprop("ro.product.name") == "a510_...");
5- Zip all files again and name it update.zip.
6- Flash it with CWM.
7- When asked to avoid bootloader installation say "NO". This will restore the original bootloader and lock it again. You will not have CWM any more but I think this is what you want right?
That's all.
From this point on you are at factory state. If you connect to internet very likely Acer will send you an OTA update but it's up to you to install it.
Regards.

fast , accurate ! thanks a lot

but i have only image ...

I tried to get back to factory state , but i got an "instalation aborted" message every time that i tried
I downloaded the R28.RC02.WW.GEN1 from the site that you linked, unzipped , added "#" character to the first line at the update script file, rezipped and renamed to update.zip
I also copied the file to ext sd and internal sd
I'm currently at franken a700 with nothrills recovery

@ursur,
I would recommend:
- Unzip and zip with another application. Some times wthis could be a problem.
- Edit the script with a linux compatible editor like Notepad++, freeware, google it. Avoid Wordpad or other editors that insert line feeds of CR.
It works for me using internal or external SD.
Regards.

One Hint:
8- When CWM asked to avoid root say "NO".

What does it mean 'flash with cwm'?
IS it this command : fastboot flash recovery update.zip?
Sorry for stupid question.

Recovery verified failed
Hey guys,
i installed a stockrom from acer with your instructions and it was completly done. I had Nothrills 700 Franken before.
i just answerd this question : When asked to avoid bootloader installation say "NO". This will restore the original bootloader and lock it again. You will not have CWM any more but I think this is what you want right? with YES because i wanted to keep cwm.
The tablet restarted normaly and when setting up acer told me that there is a update so i did the update.
Now the tablet restarted and i get the message : booting recovery kernel imag
and in the second line: Recovery verified fail...
in the middle of the screen you can see the acer logo.
WHAT CAN I DO NOW??? I can't reboot the tablet. Holding the power button get no impact. Shoud i wait till the battery is empyt and then?
I read smthg about fastboot and get a stock recovery. Is that a possibility? if yes, who will give me an instructions what i have to do.
Thx for your help.
But at the Moment i'm very desperate
P.S. Sorry for my bad english

Ok, about 2 months ago, I flashed to a Nothrills ROM and all. Then, I wanted to go back fully stock, and I did the same as you mentioned above.
Today, I tried updating my tab OTA and I am getting "Recovery verified failed..." error. Nothing that I can do. Mind you, I was on stock ROM and all, just that I was rooted.
Thanks.

maybe just root is a problem

With system powered off, press and hold ‘Power’ and ‘Vol -‘
b. When the system vibrates, release the ‘Power’ button.
c. When the system vibrates a second time, slide your finger from ‘Vol-‘ to ‘Vol+.”
d. When the system vibrates a third time, release that button.

Tutorial to backup to original firmware on A511
You have a Acer Iconia Tab A511 with e.g. A510 (Custom-)ROM without 2G/3G and you can not install the A511 firmware, cause Status 7 or Status 4 errors?
Deleting the line in the install script with the name of the device doesn't work? Using an other editor and 7zip for repacking is not the solution?
try this way

What problem exactly are you facing?? Can you boot into android??
Do u have CWM recovery or TWRP??
Did u follow all steps?? r u using the same SKU as u r tablet??

The problem I am facing is that I do not have a recovery working. I cannot access recovery at all. I was trying to update the tablet by downloading the official firmware and placing it on the root of the sdcard. But it wont recognize the update when in Android. (I can boot into Android.)

HI
I think then try to re flash your recovery first using fast bot method...then try this guide again..
or the last option is send to ASUS..:silly::silly::silly:

Is this method work with every firmware, and is it work on me301t?

After Update 7-29-13
Similar problem 300t does'nt go past the asus startup screen, when i tried to do a wipe and restore it just goes back to the asus load screen (with spinning circle)and sits and spins, so then I tried reinstalling from micro sd card using the trick where u rename the file to EP201 after trying to reinstall the newest version and an earlier version from the microsd and got the dead android (same results for both )and when I use recovery I get the android guy and loading bar and he fall over dead with error, but when turning it back on, everything goes back to the stuck loading screen. If you connect the tablet to a pc it says usb driver install failed and if you try to force driver install through device manager, the driver install completes but then says the device cannot start. asus sync does not see it , I want to try to put the ep201 file in the SDCARD folder in the internal sdcard but cannot perform this because the pc cannot see the tablet. any help or suggestions would be appreciated.The un rooted tablet Was running 4.2 just fine before i tried the new ota update 7-29-2013 and thats when this happened , I tried to call Asus, since my warrenty had expired last month they said they would fix it , but it would cost me .....i explained that their update is what made it unusable, but they didnt say anything about that fact. and told me the same .... if you have a idea or have solved the same issue PLEASE post
Thanks

[Q] Attempted CM11 Upgrade Gone Wrong

So I've installed/changed ROMs numerous times but must have slipped up this time.
Attempted to use TWRP to install CM ROM; got an error (can't recall exactly). Used TWRP option to reboot and now I'm stuck in an endless Asus logo loop.
I can get to the 3 icon screen (RCK - Android - Wipe Data).
What are my options at this point?

The tablet drained down to 0% overnight (due to the boot loop). I downloaded your file and transferred it to the microSD card and then plugged in the tablet to charge.

I rooted/unlocked the device more than a year ago; didn't right any of that down so no idea.
Last ROM I was using was a CM build.
Never used fastboot or adb (AFAIK) so no idea if I can; never pulled a logcat - is there a process for that somewhere to follow?

UPDATE - it appears I can get into APX mode - PC doesn't find the drivers so that's my next step. Once done what are my options?
No luck on TF700 APX drivers. Windows sees it as "Unknown Device". Found 1 thread on Google that referenced TF700 APX drivers but the file it links to is gone.

[Q] Stock Mini won't boot past splash screen

Hi
I'm trying to fix my Mother-in-law's HTC One Mini.
It suddently went black, and when she tryied to turn it back on, it won't boot past the splashscreen (with the "One" logo) It just freezes there.
I can reboot it by holding the power button for 10+ sec. I can also get into the bootloader.
I tried to go to recovery, there was a red triangle and exclamation mark and no options. (Is this normal if the phone is not hooked up to a computer?)
I have ADB drivers installed for when I was rooting my One X.
I think she was doing a lot of updates from play store when i shut down.
Is there something to do, besides doing a factory reset?

Ok i got some more information.
It turns out that she was doing an OTA update when the phone crashed.
Is there ANY way to get the pictures out of the phone?
#EDIT
Don't know if I ruined everthing... But I installed a custom recovery TWRP, thinking I could mount the internal storage and dump the data to my computer.
In the file explorer in TWRP, the "sdcard" folder i empty.
Did I wipe it when I unlocked the bootloader?

I wan't to try and recover some data from it by pulling a raw dump of the flash memory. Using this method http://forum.xda-developers.com/gal...de-internal-memory-data-recovery-yes-t1994705
BUT Before I can do that I need the phone to boot up. What is my best route to getting a working copy of Android into the phone?
Is it possible to push it via ADB? I wan't to write as little to the memory as possible because I'm trying to recover files.
Also afterwards, how do I get her phone back to stock firmware? I have looked at this method, but can't realy figure out it would get me back to EU stock phone.

No backups :-/ She's an average user...
I managed to make a raw dump of the entire flash memory and run data recovery on that. But I didn't get any files. (Only found system files)
Now I want to try and get it back to stock, but for some reason I can't S-OFF the phone.
