[Q] Transformer TF101G unable to boot to recovery.

Hi all,
This may sound like an old problem but believe me, it's not. Let me explain.
I've rooted my Transformer TF101G (B90) last year sometime on 3.2.1. This works fine with no issues. I've flashed ClockworkMod after installing ROM Manager. This worked fine, I can boot normally, I can boot to recovery, no problem.
With the latest update available from ASUS via the web, I decided to to allow the annoying icon complaining about upgrading to download and run the upgrade. After downloading the update the Pad rebooted so if to install the new update. This landed me on the CWM with an error message that stated the verification (or something failed). After this, the Transformer wouldn't boot directly to Android, but ended up booting to the recovery partition every time. I had to use the fastboot option to "cold boot" into Android.
This was annoying, so I googled and found the solution on this forum to fix the issue with 5.5.0.4 that kept rebooting to recovery. This solved that problem and I was still able to boot to recovery whenever required.
I decided to update CWM to version 5.8.2.1 via ROM Manager. This seemed to work via ROM Manager, but restarting the transformer and going to recovery showed version 5.5.0.4 still. So I went back to ROM Manager and it showed that it was upgraded to 5.8.2.1. I decided to update this to ClockworkMod Touch by purchasing it via Google market to support the guys that do development on it. This claimed to install also. "Reboot into Recovery" from ROM Manager still showed version 5.5.0.4.
I was now very confused.
So I decided to downgrade CWM from the 5.8.2.1 version it stated was installed to version 5.8.1.9. This worked according to ROM Manager, but rebooting into recovery still showed 5.5.0.4. I mean, WTF!
In the meanwhile the freeken update icon on the task tray still complained about updating Android. I allowed it again to try and update. At the point it rebooted it left me stuck on the "EEE Pad" screen.
Booting up with Vol - and Power takes me to the screen that gives you an option to press Vol + to boot to RCK. Doing so the Pad freezes at "Booting Recovery Kernel Image". My PC then detects USB ADB interface but any adb commands respond with "error: device offline" or "error: device not found".
Booting up with Vol + and Power leaves the screen blank. My PC then detects an USB APX interface. Using "fastboot -i 0x0b05 flash recovery recovery-clockwork-touch-5.8.2.1-tf101.img" only responds with "waiting for device".
The only way to boot my tablet at the moment is to use the "cold boot" option.
I would like to think I've tried everything out there and would appreciated anybody that could point me to maybe something else I could try.
PS: In ROM Manager I get "An error occurred while attempting to run privileged commands" when I use the "Fix Permissions" option.

Fixed the privileged error by installing Busybox, but still unable to boot to recovery even when reinstalling CWM with the "Erase Recovery" option ticked.

I had the same problem. It seems the 5.5.0.4 or whatever recovery has borked the transformer. First, I was just in a recovery loop and when I followed how to get out of it, I have no recovery at all now it seems. I need to find a recovery.img and fastboot to manually install it but I can't find a recovery.img that is current.

I can't get fastboot to work either. I though I might reinstall ClockworkMod via
fastboot.exe -i 0x0b05 flash recovery recovery-clockwork-touch-5.8.2.1-tf101.img
but it never connects.
Is there no tool that could be used from the adb shell that could re-flash ClockworkMod or even the original recovery (if that is available somewhere)?

Same problem here(tf101g): tried to update to ics.... stuck on cwm 5.5.0.4
Resolved problem using: echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
Now i can't access to cwm, even if i update to the last cwm touch....paying...any idea?

recovery
Sorry for my bad english,
I think I have the solution
First invites you down the driver and the nvflsh see appendix are the drivers are too large as a single file
2 go into the apx and the modern transformer connected to the PC
Third drivers instalation
4 instalation nvflasch
then you have a new recovery
This worked for me
ps I have a B60

I tried this combined with the instructions on android.modaco.com/topic/335416-nvflash-setup-instructions-drivers-links-active because I'd never used nvflash before.
I managed to boot my TF101 in APX-mode, but as soon as I do any nvflash-command (e.g. nvflash --sync) the connection to the TF is lost:
C:\Program Files (x86)\nvflash>nvflash --sync
Nvflash started
rcm version 0X4
Command send failed (usb write failed)

Click to collapse
After that I have to reboot the TF and shut it down again to be able to go into APX-mode again.
What do I miss? Mine is a B80.

Oops. Fastbook doesn't seem to work either. Any ideas?

Yeah, I can't get fastboot to work either. I still have root access on the device. Is it not possible to flash the recovery from to root prompt on the device?

I tried using ADB. That way I actually can access the device and copy the recovery.img to the device using:
adb push recovery.img /data/local/recovery.img
adb shell
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock2 /system
# cd /system
# cat /data/local/recovery.img > recovery.img
# flash_image recovery recovery.img
Click to expand...
Click to collapse
Works out until the last step. Then I get a message sh: flash_image: not found. Am I missing some files I have to flash first or have I forgotten something else?

Success!
Finally I succeeded!
Flashed recovery using Gnufabio's RecoveryInstaller. (After that the TF101 rebooted itself but still got stuck at the splashscreen. Did a cold Linux-boot).
Opened an ADB-session:
C:\Program Files\...\platform-tools>adb shell
/ # su
/ # echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
5+0 records in
5+0 records out
5 bytes transferred in 0.039 secs (128 bytes/sec)​/ # exit

Finally, using ROM-manager I downgraded to CWM 5.5.0.4.
After that I was able to boot into recovery, but not from ROM-manager. I had to hold Vol- but at least I have a working recovery and was able to upgrade to ICS.
I'm not sure if the first step was really necessary but this is how I did it.

Hey hans_zelf,
Wow, I'm glad you got it going. I'll give it a go aswell and give feedback here. By the way, where did you get the recovery.img file you originally tried to flash?

Not really sure. I did a search within the forum and found several img's and zips.
But in the end I didn't need it because both RecoveryInstaller and ROM-manager download their own.

Ok,
I did the following:
adb shell
su
echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
exit
Used ROM Manager v5.0.0.6, selected "Erase Recovery" in the settings menu, then flashed ClockworkMod 5.5.0.4, and powered down.
I then tried to start with Vol + and Power, just a blank screen but the 0955:7820 usb driver loaded. Then I used Vol - and Power, it booted to the Eee screen with the blue progress bar, after this is booted normally to the OS.
I powered it down again, and this time booted with Vol - and Power. Got to the screen that says use Vol + to load Recovery. I did that, and Bobs-Your-Uncle !!!!! IT WORKS !!!
Thanks hans_zelf, I'd still be stuck if it wasn't for you !
PS: I think the trick might have been to flash the 5.5.0.4 back, I'm not sure, and I'm not trying this again

You're welcome, but all I really did was combine some very helpfull tips from this forum
In the meantime I flashed my recovery to repacked Touch CWM v5.8.1.8 by Roach2010. Works like a charm. Not only touch support but also keyboard!

Thanks hans_zelf & PeekNPoke. Got my tf101 back into recovery mode from following what you guys said. I had this problem because I upgraded CWM in Rom Manager. Is that what happened to you guys? If so I think this should be stickied because if was a easy mistake and this is the only thread I could find that helped get my recovery back. Thanks again

Yep. Mine was also barked after I upgraded CWM from ROM-Manager.

[Q] TF101G (B80) lost CWM but still Root

Hello,
I tried upgrading CWM via ROM Manager...and can confirm: It dont work
If I try to go to CWM, equal how (Software or Hardwarebuttons) he says starting CWM and nothing happens. Only way is to boot with Vol+.
Also failt install CWM via apk.
Only way I can imagine is to flash a old rom with CWM, maybe honecomb, via MicroSD? Any working link to such a old rom? And how to flash?
Thank you in advance.

You say you lost cwm, so how are you going to flash an older rom via cwm?
Team Rouge has an nvflash version of their recovery or try RecoveryInstaller

Rom manager is bad news for the tf101, please don't use it in the future.
To fix this (Run in an adb-shell on a computer or terminal emulator on the device, if you can boot, I hope you still have root.)
Download any cwm-flashable recovery. Extract the recoveryblob file out of the zip and place it on your tf, via mass storage or ADB (I recommend rouge)
Then run these commands in term em or adb shell
Code:
su
dd if=/your/blob/here of=/dev/block/mmcblk0p4 (Please note the your/blob/here part, you need to type the path of where you placed your recoveryblob here)
reboot
Should get you backing into a non-borked recovery.

Have read about it. But you had give me the way to try.
Have tested Rouge and Rouch recoveryblob.
Both the same.

Via and with are the same... xD pointless from here.
Last step is to try to reflash the bootloader EBT partition and see if that's the issue, since your recovery flashed fine.
If not, NvFlash here you come!

Ok. How do I do that?

Blobunpack a stock OTA from asus's site,
then take the .EBT rename it to blob with no extension and use the same command to flash it.

I think the best way now is to go back to stock.
Same way use NVflash to flash full firmware and start again rooting and installing CWM...

Agree with you. But then I need a link to a easy rootable firmware (up to 8.6.6.19 for Razorclaw) and a short description how to flash.

Try my PERI one-click, it should install recovery and walk you through rooting just fine, if you can boot into android. If not just flash the latest OTA completely (Everything including ebt) should fix any recovery and bootloader problems. Then you can run PERI and it will install recovery and root for sure. If you want

I think I going to be crasy, because 3 days later and no sucsess
to sum up:
1. Gnufabio's RecoveryInstaller.apk
work, reboot, stuck, Power&Vol-, Vol+ stuck at booting recovery kernel image
2. NVFlash
somebody wrote NVFlash is inpossible for B80
seems to be true:
rcm version 0X4
Comand send failed (usb write failed)
3. my last hope: ADB
a) Power&Vol+, adb shell-> device not found (Device Manager: Nvidia USB boot-recovery driver for mobile devices)
b) Power&Vol-, Vol+, adb shell:
List of devices:
0123456789ABCDEF offline
Device Manager: Asus Transformer ADB Interface
c) normal reboot, stuck on EeePad Screen, same as b)
Now I'm on the end of my ideas...
BTW. Tried also this, but dont work.
echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0 in Terminal on the pad->done, but nothing happens
BTW2 Im on Megatron 1.1.4 - It works but I cant take part of the development on this.
BTW3 @Thing o Doom: Your PERI also dont work. Think it belonges to the ADB Problems.
BTW4 If I try to going into recovery there is written:
Android WW_epad-user bootloader < e> released by WW_epad-8.6.6.23-20111202
Checking for Android ota recovery
Skipping android ota checking
Checking for RCK..press key <VOL_Up> in 5 sec to enter RCK
Booting recovery kernel image
If I understand that right it may possible to flash a OTA-Update with this method?
Which schould i use?
BTW5 Tried to copy Rouges recoveryblob to mmcblk04p. Was sucessful, but nothing happens

EDIT:
I just talked to Rayman and this won't work for you, TF101G devices have another SBK. I'm sorry.
Hi there.
I made this tool for you.
http://www.mediafire.com/?5wi7ga8c7b4wz1p
Unzip and start EasyFlasher.exe
1. Put your tablet in APX mode (Hold down Power and volume up)
2. Install APX drivers if needed
3. In EasyFlasher, click on the "Wheelie" button, this prepares your tablet for nvflash.
4. Click Flash recovery.
This should work if you have a SBK2 device, I have heard that newer TF101Gs have a newer SBK, if you have a newer SBK, this will not work.
EDIT:
This tool will only work with any SBK2 device at the moment.

Have NO Recovery

Hi all !
Two weeks ago I somehow lost my recovery...
I had CWM 6.0.2.1 and decided to flash compatible TWRP zip 2.6.3.0 and switch recovery. I think i forgot to wipe something. It did flash it, but not successfully. When I tried to enter the recovery it stucked in "searching RCK" and didn't enter the costume recovery. I rebooted it and it get stucked on the ASUS screen. So now I have 2 options:
(The tablet is off)
1. Turning on- holding POWER- stucked on ASUS boot screen.
2. Holding POWER+VOL DOWN- enters RCK. from here I have two options, again:
2a. Enter recovey- press VOL UP - doesn't eter recovery; stucked at "searching RCK".
2b. press nothing- I have two options:
2b.a. cold boot - boots normally to the ROM (CM10)
2b.a. wipe data - haven't tried it, but i belive it will wipe my data XD
I've tried PERI and 1ClickTransformerRoot - no results...
In my opinion, the main problem is that the tablet can't reboot normally...
I need your help, I'll apritiate it a lot !

Wipe data won't wipe data as it relies on stock recovery.
Here is what I would do:
Download the TWRP you want to use.
Unzip so you have the TWRP.blob and put it in the /sdcard/ directory.
Then run the following in a terminal:
Code:
$ [b]su[/b]
# [b]dd if=/sdcard/TWRP.blob of=/dev/block/mmcblk0p4[/b]
# [b]reboot[/b]
Wait for it to fully reboot (should see an Eee Pad with progress indicator on boot)
Once it is booted, reboot to recovery.

I would add to first do this when booted to the ROM from either terminal or through adb shell:
Code:
su
dd if=/dev/zero of=/dev/block/mmcblk0p3
And reboot normally. This will clear a flag or something that's causing the boot loop and allow normal reboots. Then do as Frederuco says above.

Can I try a similar method with CWM ? :fingers-crossed:
Btw. you two are great !

You can do the same with a CWM blob file.
Also, if you have a TF101 (non 3G) you can boot to APX and install using NVFlash (EasyFlasher).

I was trying to root and install KatKiss on my Asus SL101.
Somehow i messed it up.
I managed to root it, installed twrp but couldnt get into recovery.
Somehow i installed CWM too and when i hit format it stucked.
Now i can enter recovery CWM but it says it cant mount the sd card where i put the Katkiss, the apps and the SL101 compatibility pack.
I cant go back into the original rom cause it just says asus and the cyrcle goes on and on.
I could use some advice on how and where to enter those lines as i am not very familiar with android

Have you tried cold boot?
Read through the OP in order to cold boot into ROM:
2. Holding POWER+VOL DOWN- enters RCK. from here I have two options, again:
2a. Enter recovey- press VOL UP - doesn't eter recovery; stucked at "searching RCK".
2b. press nothing
2b.a. cold boot - boots normally to the ROM

2b. press nothing
2b.a. cold boot - boots normally to the ROM
in my case
2a. it does enter recovery cwm, but cant format and it doesnt see the sd card - cant mount it.
2b. press nothing
2b.a cold boot - doesnt boot normally. it stays on the asus logo page and the bubbles rotates
therefore i dont know where could i install that terminal

I too am having this same problem. I had one of the Cyanogenmod nightlies installed, I wanted to upgrade to katkiss so I tried to install TWRP. I installed it using the TWRP app. I thought I installed it successfully, but I didn't. I got stuck at the boot loader. After cold booting android, and installing Rom Manager, I find out that both CWM and TWRP are installed some how? I tried the easyflasher method, but every time I try to install the APX drivers, Windows 8.1 gives me an error about a corrupted hash. I also tried Frederuco's method, and that didn't work either.

Rommanager = not good for Asus tf101. Also, you don't need any app for installing twrp. If you have a working, up to date recovery, you should be able to flash the twrp zip directly from recovery. I recommend my builds of twrp, of course.

I still was able to unlock and root the device but I still can't get past error or figure out how to install a new recovery.
Any help?
Thanks

The error triangle means you have to install a recovery (before you use it).
Make sure the recovery you will install is compatible before flashing it.

All instructions I find for flashing a recovery have you booting into RCK to flash it. Is there another way?

You can use Terminal Emulator to flash it if you are rooted correctly.
Code:
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Make sure you install the -42 version.

Thanks for the help. I finally can boot into recovery. It took a bit to realize sdcard meant internal memory not the microsd like on my phone.
Thanks button hit. :good:

TF300T 4.2 TWRP Error

Hi XDA,
I am a complete noob, and this is my first time posting, so bear with me.
Some time ago I rooted and unlocked my TF300 with SuperSu. Recently I wanted to upgrade to 4.4 kitkat. However, my Tablet was stuck at Andriod 4.1 because of the the unlock.
I went to manually update my TF via the Asus website. I installed the 10.6.1.8 using my TWRP 2.5, and Oem 4.1 OS. Installation worked just fine. After install, I booted up and I had 4.2 with everything working correctly.
Next step was to install TWRP 2.7.0.1. I reset my TF and went into RCK to see something went wrong when updating.
My TWRP will not load, and I get the Android on his back with the red triangle when I try to enter RCK.
Thanks in advance!!

I managed to install 10.6.1.27, but it did not change anything with my boot loader.
I downloaded motochopper, but that didn't seem to work, just told me my abt was out of date. SuperSu isn't working now either, "No Binary, There is a problem."
How do I install TWRP 2.7 with no boot loader? Please help.

Most people just install TWRP via fastboot like
Code:
fastboot -i 0x0B05 flash recovery twrp.blob
You could try using other root methods, like Framaroot or Kingo. I think Kingo was reported to work on the latest stock version.

I will look into that, but I am pretty sure I was already rooted, unless losing my boot loader means I am no longer rooted.
Another thing, I can't find a twrp.blob for 2.7, just a zip. I have one for 2.5, but that is useless because I already have 4.2. I also have not been able to find a working link to fastboot.
If anyone could give me a link to the fastboot or a link to a tutorial, that would be amazing. I have done my research, but all the lingo and different methods can be mind bending.
Thanks

You can get the img (which substitutes as a blob) from extracting it from the TWRP 2.7 zip file.
1) You will need ADB and fastboot for this: http://forum.xda-developers.com/showthread.php?p=42407269. I would suggest keeping the tablet at least at 50% battery.
2) Install Naked Drivers. This may be optional for you. If you can proceed to the next step without, you won't need it.
3) Enter fastboot by rebooting and holding down the power button. TF300 enters fastboot automatically since this is 4.2 BL.
4) Next we need to enter a command. In side the ADB folder, hold shift and right click. Then select Open command window here.
first check to make sure the device is connected:
Code:
fastboot devices
The device serial number should be listed.
enter command:
Code:
fastboot flash recovery twrp.img -i 0x0b05
Blue bar on device will fill. Be patient.
5) Reboot the Device back into Android. This is an important step.
6.) Go back into TWRP and install what you want.

You are amazing. I will give it a try tonight and report back!

Installed adb fastboot. However, my device does not automatically go into fastboot, I still have to hold down the volume key.
Once I am in fastboot usb (with the 3 icons), I fastboot successfully and get the serial number, then when I type the 'fastboot flash recovery twrp.img -i 0x0b05' command I get this error: cannot load 'twrp.img' : No error
I am attemping to use the 2.7.0.1 twrp from the 4.4.2 page. I have extracted the recovery.img (tried renaming to twrp and left it the same) and placed it in the root of both my external and internal sd.
I have now tried it with .zips .img .blob and I receive the same error everytime. Not sure what I am doing wrong now.

Put the twrp.img into your ADB folder, where you installed it. Then run the next command.

Awesome! Worked like a charm. twrp 2.7.0.1 installed perfectly.
Then I tried to flash the cyanogenmod. Said it installed fine, but it just gets stuck on the loading screen...

I am trying to do exactly what TallMilk is doing...put Cyanogenmod on my tablet. It is my understanding that I have to unlock my bootloader though? Which I have tried doing a million different ways with the Asus Unlock tool which always gives me an error.
If I follow the instructions posted above I will be able to flash Cyanogenmod without unlocking my bootloader?

Finally got it to work. I had to do a wipe first, read about old roms interfering with new installations.
SilentSpartan, I used SuperSU last year to root and unlock my tablet when it was still a 4.0 android to flash to 4.1. This recent update was from 2.5 TWRP on a rooted device running 4.2. When I installed 4.2, it blew away my TWRP, and I had to flash the new TWRP 2.7.0.1.
That flash from OEM fastboot to TWRP 2.7.0.1 is what I needed help with.

Damn, so I'm screwed. Why does Asus have to such so much...? You can no longer unlock afaik.

You're going to have to unlock no matter what. Did you try both v7 and v8 of the unlocker and calling Asus Support to tell them to put your serial number back into the database (get a manager)?

I've tried every firmware and unlock tool combination. Nothing works. I sent them an email a day ago. Depending on there response, maybe I'll try calling. I'm so fed up with this tablet, I'm about to throw it out my window. $400 POS. :good:

Did you ever get your tablet fixed? I am having some problems myself after a miserable m9 update.
