Desperate and not working over adb

Hello,
I`m in trouble with my EEE pad. I don`t know what to do to recover my software . Yesterday I did make a Revolution HD Super Wipe Full,and forgot that my battery was not enough charged. My pad remained without battery and it shut-down. Now it remains with the Eee pad Asus logo on the screen. I can enter in APX mode. Also connect with the adb. I attach here one print, maybe someone could help me, what to do....

Can you boot into recovery?
Push Vol down + Power button
When you see words scrolling at the top left
immediately push Vol up within 5 sec.

Um im not sure but couldnt you push the individual images??
Do you have NVflash?
Im not sure how you would do it through adb but maybe something like
/adb devices
/adb remount
/adb push system system.img
/adb push recovery recovery.img
/adb reboot
then go into cwm and flash kernel
If that doesnt work and you have nvflash you can push the images through that or use the OLiFE script so you dont have to write
All else falls i hope someone far more knowledgable than me can help i tried
Sent from my tf Enigmatic V1 Alpha 1.59Ghz Panda.test

I tried with Nvflash, but I`m getting everytime error. My pad is very new. The S/N begins with BB0KA, and the flasher does not workThe ony think that work is with the adb. . .I`m recieving this error when running adb -push system.img. Danzano, I did not find the OLiFE script. Where I can get it..

PROBLEM SOLVED: For other people that encoured my problem on the TF101,do the following to recover:
1. Download from asus your zip firmware (note: be sure to download the rigt version for you ex: (WW, US).
2. Rename your downloaded file to " EP101_SDUPDATE.zip "
2. Format your sd-card to FAT.
3. Create obligatory on the sd-card a folder "ASUS"
4. Put the renamed "EP101_SDUPDATE.zip" file in the created ASUS folder.
5. Hold power button + Volume key down to enter recovery
6. Press within 10 seconds the +Volume key
7. You will see that the update progress-bar will beginn to work . Thats all, and enjoy it...

Back to stock

I rooted, and loaded cm9 rom. I prefer stock rom but when I restored my backup there was no wifi (apparently a common issue). Anyway, I am looking for a way to get back to stock rom. I downloaded firmware from Asus but dont know if that is what I need or what to do with it. I am using the twrp recovery
Thanks for any help

All you have to do is download the full Asus ZIP from my thread and flash in CMW and it will restore your fully stock ROM without recovery

ok thanks now to figure out how to get cwm into my tablet-- right now trying to install sdk

i installed something called eclipse.. I plug in tablet and get to fastboot mode then-- nothing happens- anyone know how one "flashes". Obviously techno noob here

this worked
Terminal Emulator Method
Install Android Terminal Emulator on your tablet.
Download the ClockworkMod Recovery image file directly to your tablet, preferably in the root of the /sdcard directory. Take note of where the file is saved. Rename the file to cwm-touch.blob.
Launch Android Terminal Emulator on your tablet.
Enter the commands below. If you did not save/move/copy the image file to the /sdcard directory, you need to replace /sdcardin the second command below with the correct directory where you saved the recovery image file to.
su
dd if=/sdcard/cwm-touch.blob of=/dev/block/mmcblk0p4
Reboot your tablet. The blob file will be automatically installed as your tablet reboots.

You can uninstall Eclipse. It has nothing to do with Android or flashing anything. It's an Integrated Development Environment, which is kind of like a word processor for programmers. The only relation it has to Android is that it supports the Java programming language, so a lot of Android developers use it. If you're not going to be writing apps or messing with Android source code, it's probably best if you uninstall Eclipse, just because you won't use it, and it's taking up storage space.
Also, what were you expecting to happen when you put the tablet in fastboot mode? It just opens up a serial connection with a host (in this case, your computer) and allows the host to access the tablet via fastboot (sounds confusing, I know; it's not particularly fast, and doesn't have much to do with booting anything; it's like ADB but for low-level [hardware] flashing) and run commands. The tablet itself does nothing except display the message that it's in fastboot mode. Once the tablet says that, you run fastboot on the computer.

thanks for the reply. Now I have a brick---tried to install stock rom and hangs on asus with the wheel going round and round. It deleted my cwm so now no recovery on tablet. When I go into fastboot, it doesnt seem to recognize my tablet adb devices--nothing comes up

In my device manager I see no adp drivers- the only driver which keeps installing when I plug in the tablet and go to fastmode is the asus bootloader interface so I cant do anything with the tablet--- no recognition of device with adb devices command Help please

If you're in fastboot, ADB won't recognize the tablet. You need to use the fastboot commands with fastboot.
What to do:
-download the CWM blob on your computer
-put the CWM blob in the directory on your computer with the fastboot program
-boot the tablet into fastboot, and flash CWM
-boot into CWM, and restore the nandroid backup you should have made.
Alternately, if you didn't make a nandroid backup, you can boot into recovery, push the Asus stock ROM to /sdcard on your tablet via ADB (I'm assuming ADB works in the stock recovery), then reboot into recovery, and it should flash the update automatically. This will erase ALL your data, including /sdcard.

is cwm blob recovery.img?

I'm not sure if flashing .img files works with this tablet, but you could try. If it doesn't work, go to the place you got the recovery (as long as it's not from ROM Manager, and you're positive it's not the TF201's recovery), and there should be a file that ends in .blob. That's the one you need.

then I just place it in the same directory and click on fastboot? or is there more to it? seems to be having trouble with drivers mtp driver not installing???

I don't use Windows, so I don't know about the drivers. There's a thread in the development section with all the Windows drivers you need, though.
You put the blob in the directory where fastboot is. You open the command line (open Run, and type "cmd" [no quotes]) and run the fastboot command from there.

got it thanks cwm is back

[Q] Problems Flashing Recovery on Asus TF300T

I have tried literally every method that I've found on the net to flash recovery on my Asus TF300T, and nothing works. The tablet stays at "Starting Fastboot USB Download Protocol" when I plug it into my computer. When I open a command prompt and enter in the command lines, it just keeps saying "Fastboot is not recognized as an internal or external command". The guides say that after entering the commands, a blue installation bar should appear on my tablet, but nothing happens at all. I don't know what else to do. I updated to the OTA 4.1.1 firmware as soon as I got the tablet I can't root nor can I find a way to flash any type of recovery. Can anyone help? Thanks in advance...

Installing TWRP.
I added the file to the message. The latest version of Android SDK Tools pulled adb and fastboot and made a command file to install it, so as not to type it manually.
This archive should be unpacked in the root of drive C. Folder was adb-t. In this folder, copy the file to your custom recovery tablet model and its version of the android, rename it to twrp.blob. We go on the tablet mode fastboot, connect the tablet to the computer and launch twrp.bat.
Installs the custom recovery, expect to fill the display screen tablet and press the space bar (any key) on the keyboard to restart the tablet. Remove the cables from the tablet.
Attention! The current archive file contains the last (2.3.1.0) custom recovery (twrp.blob) for TF300T with JB. If you have a TG or some version of android - do not forget to replace twrp.blob of the edition you need.

Thank You!

[Q] broke asus tf101 eee pad transformer

Hi.
It's been some time since i tried fixing my Asus Transformer...
The problem is : If it has battery life. It boot's and gets stuck on the first screen.
With the logo "eee pad" .
If i turn it off, it automaticly reboots and gets stuck in the same screen.
If i try to get into recovery mode.
Vol down, Powerup... and the vol up , i can see the few line's of code , saying it will boot into recovery mode.
but while trying to start recovery mode the icon changes to a fallen android and an "! triangle above it
I've been looking around forums evrywhere but i cant find a solution for my exact problem.
can anyone help?

Quickly, with the info you provided, I would think your firmware or storage may be damaged.
Can you access ADB? Sometimes you can while it boots, even if it doesn't fully boot. That would allow you to check logs and back up data.
Can you access APX? It has nothing to do with Android, it's a part of the device made by Asus to allow you to "inject" a firmware inside the device while it's in "brick" state.
If you can access ADB, you can "pull" the files you want from the device to your computer. You can see information on ADB here. Basically you install the package from google and connect the device to your computer, then run a set of commands.
If you can access APX (chances are you can unless there's hardware damage), then EasyFlasher can push a stock firmware back to the device. This will wipe your device 100% back to stock and you will lose all your files.

With my Ubuntu, if i do the command ./adb device
Then i can see a number. So the device is connected i think.
I am not sure if i can access APX, i do not yet how to test tis yet.
Is there an easy way to see / test this in ubuntu ?

APX mode is just a black screen, but your PC will install drivers and see the device when you enter that mode
Hold Volume up & Power until the USB connect sound appears, now you are in APX mode - there will be nothing on the screen of the transformer until you are flashing a new ROM maybe
What serial number is your TF ?
NVFlash is the quickest way to get back to 100% working stock

That's good, its working, you can watch command prompt I think if it stays open to watch the progress as it sends the files across, can't remember exactly, but the TF should reboot on its own when its done
It can take 10mins or more iirc so just leave it to do its thing, then it shoot boot up
The only thing I remember having to do, was once it had booted, and I manually reboot the TF, it would hang on a black screen (Only that first reboot though) holding power for around 30 seconds, then powering on normally fixed it and it never does it again, just that first boot
Might not even happen on yours, could be a fault on my TF

You could flash the pre-rooted versions too although I think it's easy enough to root yourself these days
This is the XDA Fileserver for different ROMs if you need them
http://www.xdafileserver.nl/index.php?dir=Asus/Asus+Transformer+(TF101)
I was just reading someone else who had the same display stuck on their TF while trying to use NVFlash and they said re-downloading the ROM and trying it again fixed it
So if this fails for some reason, try another NVFlash ROM from the XDA Server

NVFlash contains everything you need, ROM and NVFlash tools to install it to the TF, I've used that exact same download on mine so it should be working
Did you have any progress showing in command prompt ?
It should say something like
Deleting partition
1
2
3
4
5 etc
Then creating partiton
1
2
3
4
5etc
Then sending boot.img
sending system.img <<<<< This one takes a while
Try it a few times until you start seeing progress in CMD, if you don't see it after a few minute, cancel it again try again
There is also a Linux version of NVFlash you could try

Have you tried booting it manually by holding power for 30 seconds then powering on normally ?
That all looks like its working fine, sending the files across

I think maybe the linux version is the older .img version, and the files are .blob so it can't find anything
The one I linked you is the .img windows version, hopefully you'll have more luck with that
If not, put all the .img files into the linux folder and try it that way

Guide to fix TWRP or CWM bootloop

This is how i fix my TF300TG stuck on recovery. I hope the steps descried below will help.
Long story, short:
For some reasons, seems like the WIPE command from TWRP and CWM recovery screw the partitions.
No partitions or microSD card can be mounted.
The tablet is now booting only in recovery mode or in fastboot mode (the screen with three icons - RTK, Android and WIPE) instead of Android.
IMPORTANT:
If your tablet reboot in fastboot mode DONT WIPE IT AGAIN! Just skip step 4.
First of all, MAKE SURE YOR BATTERY IS CHARGED!
Recharge your tablet for at least two hours.During the flashing process the tablet doesn`t charge.
Use the original Asus USB cable that came with the tablet or a high quality replacement cable. Cheap cables can and will cause problems.
Use a laptop or desktop with known good USB ports. If you have problems, try a diferent computer, some USB chips can cause troubles.
Disable the antivirus or screensaver, sleep etc...
1.Download these files:
from ASUS website: http://www.asus.com/Tablets_Mobile/ASUS_Transformer_Pad_TF300TG/#support
Drivers&Tools, on the OS tab select Android
click on Utilities and download latest version of ASUS PC Sync (you will need this for drivers)
click on Firmware and download the lastest available (you will need this for BLOB file)
Minimal ADB and Fastboot: http://d-h.st/gbx
install ASUS PC Sync and Minimal ADB and Fastboot (on fastboot installer check the box that make a shortcut to desktop)
unzip the firmware file downloaded from ASUS site
you will get a second zip file, unzip this one too
the folder unzipped from the second one contain a file called blob
copy or move the folder to the root of your drive C: or D: or whatever drive letter you have
2.Installing drivers:
connect your tablet to PC
you will get a message about Windows couldnt find driver bla...bla, ignore it and keep your tablet plugged
IMPORTANT: even if you previously installed ASUS PC Sync or other drivers and Windows recognize your tablet, you still need to change the driver.
right-click on My Computer-Properties and click Device Manager
find the Asus Android device - should be with an exclamation mark on it (the driver is not installed sign)
right-click on it and choose:
Update Driver Software..., Browse my computer for driver software, Let me pick from a list of device drivers on my computer, Have disk, Browse
go to C:\Program Files or Program Files (x86), ASUS, ASUS Android USB Drivers, Android and select android_winusb.inf
Asus Android Composite ADB interface will appear in the list of device drivers - don`t hit next yet!
uncheck Show Compatible Hardware and select Asus Android Bootloader Interface from the list, now hit next
3.ADB mode:
open Minimal ADB and Fastboot from desktop - from this point, keep it open
type: adb devices - and you should see some numbers under the List of device attached - thats your tablet
if you can`t see the tablet, try this command: adb start-server
4.Booting to "fastboot":
there are two ways to do this:
a) from adb window type: adb reboot bootloader
or
b) reset and hold vol-down (didn`t work for me, but maybe will work for someone else)
the three icons will appear on screen - NOW YOU ARE IN FASTBOOT MODE
if none of the above work try this:
in adb window type: adb reboot
wait until the tablet enter in recovery menu and type in adb window:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb reboot bootloader
5. Flasing the blob
the credits for this part goes to buster99. He is the one who figured out the right commands for formatting partitions and flashing back the OS
here is his post: http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
here we go, one at the time in adb window:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system x:\your blob folder\blob (here you enter the path to your blob file, must end with blob, to point at the file)
fastboot -i 0x0B05 reboot
THE FLASH SYSTEM COMMAND WILL TAKE SOME TIME
be pacient and wait until the progress bar is 100% full on the tablet and you get the command prompt back in the adb window.
After reboot, the Android is back on.
Cheers and good luck!!

A big thank you alexhosu,
several months ago that my tablet was blocked, but I still kept hope
a solution would be found. I'm really happy for you and thank you again for sharing.
Long live XDA

me too
Thanks from me too; was enjoying 5.0 (timduru) on my TF300 when I went to upgrade and idiotically managed to get into a TWRP bootloop(interrupted a format of \data and then used 'wipe' from the boot screen by mistake...)
Your solution has saved my tablet
Am now carefully reinstalling Katkiss

Thanks
This saved my (veggie) bacon too, something went wrong when flashing new ROM (most likely user error - e.g. my fault). Tablet woud go into an eternal boot wouldn't finish booting, nandroid recovery did the same. Used this technique and have a working stock ROM from which I intend to reinstall TimDuru's Lollipop.
Thanks again

Followed the instructions.. Worked well, but getting error 963 when installing/updating anything in Play Store. Seems to be related to storage permissions. Some users are suggesting using format instead of erase. What's the difference? Could that help.
I did factory reset, reflashed and used fix permissions in TWRP but no luck...

Big thanks from me.
I killed my tablet with an accidental restore to factory defaults while in cm12, an got stuck in an endless bootloader boot loop.
my tablet came back too life at the end of section 4 after adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3.
although getting adb to talk to the tablet was a fluke.
I just kept trying to send "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" while the tablet was loading (boot looping)

6 months of believing my tablet was dead, after letting CM12 do its own update thing, and now, thanks to the above instructions, I'm back online and its working with the stock rom.
Thank you so much for this. No idea why I couldn't find these instructions before, then I just gave up, back in business now!

Thanks a lot for your guide, this is what helped me fortunately unbrick my device, i was stuck in a boot loop with a broken recovery

Another tablet saved. Know your work is appreciated.

i have the same problem, the system doesn't pass the ASUS logo, i tired to log into fastboot (reset + volume down) and i was able to see the three icons but adb doesn't recognize my device. i see the drivers are correctly installed but no working adb. Any help is highly appreciated.

Did you try entering "fastboot devices" or just "adb devices"? adb wont find your device in the bootloader, but using fastboot commands should unless it truly is not connecting for some reason.

yeah Fastboot devices worked but it was not letting me flashing the rom, when i push the blob file it says 'sending' and stays in the same state for days.

I would try moving the blob to the root of the C drive and try the 7th command "fastboot -i 0x0B05 flash system C:\blob" just to make sure sometime of file permission type issue isn't happening on the pc side. Other than that the only kind of issue I think it could be would have to be the connection with the drivers, although if erasing the partition's works fine, I don't really see what could be going on.

I followed all the steps and delete, but when loading the file update.blob I get this error:
C: \ Users \ mikel> C: \ Users \ mikel \ Android \ android-sdk \ platform-tools \ fastboot flash system update.blob
error: can not load 'update.blob'
Can someone help me out?

This saved my (veggie) bacon too, something went wrong when flashing new ROM (most likely user error - e.g. my fault). Tablet woud go into an eternal boot wouldn't finish booting, nandroid recovery did the same. Used this technique and have a working stock ROM from which I intend to reinstall TimDuru's Lollipop.
Thanks again

Hey, I know that I'm a couple years late on this. But, I was just given a Asus Transformer TF300T, and attempted to install the Kisskat custom rom. I unlocked the device with little issues. Rooted with little issues. But when it came to flashing the rom. I get his error saying that "no MD5 file found" and holds it there for a couple of minutes. Then gives me the failed install. My only option is to boot into recovery and restore the stock JB 4.2. If you could point me in the right direction, I would greatly appreciate it. I've searched the forum for someone with a similar issue, and couldn't find it. I hope that I'm not alone on this one. It would kill me to be stuck with the stock rom.

Hi i made a format data from TWRP recovery, and now i am in a recovery loop and got error of mount partitions, i can access to recovery and the screen with 3 icons, but when i plug to my pc it shows as uknown usb, i install the drivers but dosent reconose as a fastboot device, in minimal adb when i write fastboot devices the result is empty pleace help me.

Muito obrigado!
I know this must seem odd, being such an old thread and all but, after several years adding apps and changing ROMs on my wife's TF300T (my gift!) only these past weeks I had the need to search for help, after installing nougatella 7.1, which I did with success, only to stumble on endless logo loops and loading processes without conclusion. Don't get me wrong, the ROM looks great and it wasn't that hard to install but, after two weeks or so, gave me this problem and after correcting it and installing again the ROM, I got in trouble again...
After some five hours googling and trying different stuff, I finally found this thread and twenty minutes ago (around 2:AM) my ASUS returned to its (Jellybean) life!
Alexhosu, thank you so very much for such a detailed, yet easy to follow guide and, if you happen to come to Portugal on vacation and visit Setúbal, I'll have a bottle of Moscatel waiting for you!
Many thanks to Droidbound (who got me off the hook the first time the tablet went nuts!), and also Kevinthefixer, Gtanner00 and some other very inteligent, patient and thoughtful people, and all the guys who shared their difficulties and in a way helped me find the people with the fix.
For anyone interested in trying this method, I would say that it's paramount that you should stick exactly with what is asked and should pay real atention to what is the correct ROM update to download and use. If anyone needs help with translation to Portuguese, just say so.
Again, thank you so much for this!

if none of the above work try this:
in adb window type: adb reboot
wait until the tablet enter in recovery menu and type in adb window:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3
adb reboot bootloader
5. Flasing the blob

Thanks for your help :good: and I'm sorry for my basic English, but here is another tablet saved. Your instructions were clear and my tablet is working.
I hope this information helps, based in the next link (user sszyman): https://forum.xda-developers.com/showthread.php?t=2275035&page=9
in which he recommends using the following commands too:
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p2
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p8
adb shell dd if=/dev/zero of=/dev/block/mmcblk0p1
With these commands and "adb shell dd if=/dev/zero of=/dev/block/mmcblk0p3" I was able to solve my Bootloop problem.
Honestly I don't know which of the commands worked, I used all several times.
