[Q] Cannot boot into recovery - Eee Pad Transformer Q&A, Help & Troubleshooting

Hello guys,
I have a problem. I flashed todays CyanogenMod Nightly, but wasn't really satisfied with the overall performance and wifi signal strength. So I took the latest guevor kernel, which was not specifically for Megatron nor AOKP nor some other ROM. So I gave it a try. Now I have no wifi any more, and cannot boot into recovery via Rom Manager nor the "normal" recovery option the extended power menu. As a last option I considered the 2-button combination when the tablet boots. Now comes the blast in my eyes: It does not power off! After tapping on "Power off" it stucks.
I do have a backup but without booting into recovery I cannot restore ot obviously.
Any ideas? Thanks in advance.

Hold the power button for 15 seconds. Then it will turn off. then hold volume down, THEN power, then press volume up. Voila in recovery!

try the reboot2recovery app from the market aswell. always handy to have around.

Thing O Doom, thanks, I'll try later.
scottyf79, that's the crucial point! When there's no wifi, there's no downloading this app. I've always used it but now I'm pi**** I can't.

Doom,
I try with power Vlo down then Vol up, But showing android with RED ! Mark.
Cannot see recovery or CWM. Boot Looping..... HELP !!!!

well just as an update that may interest those finding themselfs in recovery bootloops, whether be it stock Asus, dev'd Asus or w.h.y.
you may have read i had taken a customers tf home with this issue to try and fix it. ended up rma'ing the unit.
Asus ended up replacing 3 circuit boards to resolve the issue!

The Android with ! is your stock recovery.
Seems like you lost CWM somehow. You'll need to install CWM or a custom recovery again.

If you're on a CM9 Nightly you have root, so just download rouge recovery or a recovery, take the file 'recoveryblob' out of the .zip file. Then put it somewhere on your transformer (Preferably MicroSD or root of internal storage: /sdcard/)
Then in the terminal emulator or adb run these commands:
Code:
su (Get pound sign)
dd if=/where/you/put/recoveryblob of=/dev/block/mmcblk0p4
reboot recovery
Then you should boot, see a blue bar, and be put in recovery.

[Q] Can't get into recovery - Rooted and CWM

Hi,
As the title says, I can't get into recovery. I rooted and installed CWM a few weeks ago (still on 3.1), and now when I press vol- and power buttons the tablet just boots up normally. It does another weird thing, too. If I press only on either of the volume keys, it also boots up.
I'm suspecting a FUBAR'd CWM install, but I'm not sure since I'm no expert.
Also, adb no longer sees the tablet. Typing adb devices shows nothing, and it used to work (otherwise how did I root, right?)
Any ideas on what I have to do? Nvflash a stock blob or whatever it's called?
Did you either intentionally or not run the OTA update? If you OTA'd after cwm - then you will need to unbrick/nvflash. You're behavior sounds a lot like mine, after I tried to OTA a cwm enabled transformer.

For the cwm thing: first of all, with your tablet turned on, try if the VOL UP and VOL DOWN keys are working. Then turn it off.
Press VOL DOWN + POWER until you see a little write on the upper left corner, then release all and press VOL UP.
For adb: turn on your tablet and connect it to your pc. On the screen of the tablet click on the icon of asus sync in the lower right corner then click on the popup. It will search for asus sync on your computer (have you installed it, right?). From that moment on, adb should work normally.
Hope this has helped.
Thanks! adb worked. Still can't get into recovery. I think it's borked, because I used "adb reboot recovery" and the tablet just rebooted normally.
Any more ideas??

Maybe that's it. I'll try it...didn't want to, because I don't want to wipe anything. This nice device of ours is so much more complicated than my SGS
Try this app, if CWM is installed correctly it should work. Cheers.

Thanks! CWM was definitely broken, probably because I attempted OTA update.
So I went and used the guide in the nvflash unbricking thread, and since that guide installs Prime 1.4, I went ahead and updated to 1.7. Now I'm rooted, cwm'ed and prime'd!!!!

[Q] Stuck at ASUS splash screen after April update (RESOLVED)

Ok so i've looked, cant find anything to help me out here... Its always possible i used the wrong search terms but i think i did pretty good...
Anyway, i had flashed i believe a CWM version of ICS when it first came out because it was easy to do, and i was able to keep root. Well I ended up with the CWM Recovery version that had the problem of constantly booting into CWM, so i fixed that and the tablet was telling me there was a firmware update, so i did it..
Now im stuck at the splash screen... When i try to boot into Recovery, it says its loading the recovery image but never does anything else. When i tried to load the other screen where you can choose recovery or the OS, i think people call it the linux screen? I dont remember, but when i did that, the big battery meter displayed on the phone for a second then disappeared... Wont turn on now, so i just plugged it in.. Is there something im missing? Or something i can do that anyone is aware of?
Check if the Android Debug Bridge works, and is your device a B60 or lower, (sbkv1)? If so you can use NvFlash to restore the tab.

Its B90, SBKv2...
Last time i tried to boot, i tried Power+Volume Up and i saw the large battery that android phones typically show when they are powered off and you plug it in.. If i remember right, TF101 typically boots up if you plug it in when turned on, but it turned on, flashed that battery image and shut off, havent been able to turn it on since... Plugging it into my computer though, it wont turn on, plugging it into the wall outlet it turns on and sticks at the splash screen, so i'm gonna leave it there for a bit and see if it charges, then i'll try plugging it into the comp to see if ADB works... I'll let you know, thanks!
To get to recovery its power +vol down. Power + vol up gets you to apex mode, blank screen.

.....don't know if I read all your info correct but to enter recovery is volume down + power until you get a message at the top of the screen then you let go both and press volume up to enter recovery or if you don't hit volume up it takes you to the cold boot / wipe data screen.
Yes, i posted that... I tried booting to recovery and it freezes when it says its loading the recovery image.
I was trying other combinations trying to remember the linux screen or whatever it was called, but either way. ADB mode doesnt work, im stuck at the splash screen.
SOLUTION: Do not do the update after fixing your TF101 if you have this same problem, because you'll have it again! Either way, here's what you do.
1) Since you cant shut off the TF101, hold the power button until the screen goes blank, then immediately let go of the power button and hold volume down. 2) The splash screen will re-appear, dont let go of the Volume Down button until you see the text at the top left corner of the screen prompting you to press volume up to enter recovery.
2) Dont press Volume Up since it will freeze trying to get into recovery. Instead, just wait and make sure your not holding down or pressing any buttons.
3) After a few second, you will be presented with two icons, one to wipe data and one to boot android/linux, selecting android/linux WILL work and boot, but you'll have the same issue as before without fixing anything if you reboot again. Follow the instructions to wipe your data. YOU WILL LOSE EVERYTHING!
4) At this point, Recovery still wont work. Boot your TF101 and get it setup and use the Play Store to download a terminal emulator
5) Open the terminal emulator and type SU and press enter, confirm superuser access.
6) Type in the following and press enter when done: echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
7) Restart your transformer, let it boot normally the first time, after that, recovery should work.
8) Problem solved, DONT install the update this time! Install a custom ROM the typical way using CWM, and your set!
So, one thing i've noticed is im being spammed out of my mind from the OS to do that system update, so i've found that the best thing to do once your bootable, is to flash a custom ROM.
I tried this but went back to the same ICS version I had before, and ran into the same problems. Ended up with a whole other ROM, and now all problems are solved!
Good luck to anyone that has this issue!
#3
so you lost all data, all apps, all settings, all the effort and work and time to config apps and settings... UGH
I am in the same boat on my TF201 after the JB update bricked my tablet... really pisses me off as Asus says RMA it (which you know they will just wipe your data) or wipe the data yourself and hop it works. So badly want to salvage my app settings and all the work I did to trick out my tablet. F***** Asus, their own update fried my tablet.

Eee Pad freeze screen and unable to recover in CWM

ASUS TRANSFORMER ROOTED 3.2.1
I am having major issues where my tablet keeps freezing on eee pad screen when turning on and the only way to start it up again is by pressing volume down and power and then waiting for it to start up.
If I try to get in to CWM i just get this message:
Android ww_epad-user bootloader (e) released by ww_epad-8.6.6.19-2011101
Checking for android ota recovery
Skiping android ota checking
checking for RCK.. press key (vol_up) in 5 sec to enter RCK (press volume up and the next line of text appears)
Booting revovery kernal image (nothing happens, should this not take me to CWM??)
Also when I turn the tablet off, it turns itself back on almost instanly but only to the Ee pad screen this has happened since last night.
Dude try following steps
Probably you might have tried all these steps, if you haven't then try it once
1) Re-install CWM by downloading from
http://forum.xda-developers.com/showthread.php?t=1213723
I use version 3.2.0.1 because it allows MMC card access and latest versions only allow internal memory access. Donload in copy to your MMC.
2) Put the MMC back in your tablet and restart with holding down vol down key and as soon as screen turns on press vol up key and that should let you into CWM recovery.
3) If you can get into recovery i would advice you to wipe everything clean and install the CWM you downloaded.
4) flash the ROM and enjoy..
Hope these steps will help..
I'm afraid that the problem is that he is unable to start cwm....or boot his TF.
serpicoUK, do you have Nvflash capabilities? (what is your serialnumber?)
if so then maybe this will help you to install cwm back:
http://forum.xda-developers.com/showthread.php?t=1446019
or maybe this will help if you still can use ADB:
http://forum.xda-developers.com/showthread.php?t=1592120&highlight=freeze+recovery
see post 12 and futher of above thread
I cant get CMW to work, when I try to flash it, it says need to reboot to go into recovery mode, all it does it freezes on the Eee pad screen.
S/N B7OK........
it looks like your CWM is broken(i know its obvious so don't laugh), so how about you trying unroot your tablet using nvflash. this link should help you in that
forum.xda-developers.com/showthread.php?t=1524302
i say unroot because getting your tablet working is more important and you can always get root back, so stop worrying about getting fixing CWM and unroot it through nvflash... btw this my personal opinion as whenever i face issue with CWM on my tablet or phone i unroot them...
you know you can always get into nvflash mode, so either flash CWM or unroot using nvflash....
What ever I do nothing seems to work.
Its now working, not sure how but it is.
Thanks for all your imput

Broken CWM

I have flashed the CWM from TF201 by accident. Now the tablet is stuck in that CWM mode. I can't connect to usb using adb mode. Power+volume down does not work anymore. Any way I can reflash the correct CWM?
THanks
If you can boot to OS - you can use fastboot to flash any recovery.. or flash TWRP from goomanager.
upd: sry..don't see about "stuck".

I have made the same mistake. Although I can get the device to fastboot USB mode. I have tried to use CWM with the restore I made before I put in Cyanogenmod 9, as well as putting on the Cyanogenmod experimental #2 for TF300. No error messages at all and it wipes data and cash without any problems.
But I get locked on the Asus boot screen and it does not continue ie I am stuck as well.
I have as well tried to use the TWRP 2.1.5. I get the Teamwin loggo screen, it wipes all the data and verifies all the filesystems and reboots. Still stuck.
Is the device bricked ?
upd:The TF300 can not be shutoff either. When you hold the power button the screen goes black, but after ~5 s the device is starting again and is still stuck on the Asus bootup screen.
if you reboot it holding vol down and power, can you get back into the boot menu, to reselect fastboot?
if holding the power button doesn't switch it off, what happens if you leave it to run out of batteries then do this?
then you can flash the correct recovery.img

Yes, I can get access to the fastboot and I have already tried to flash with the recovery.img. I have as well let the battery run out and tried it once more with the same result.
Still stuck on the asus bootup screen.
power
Hare,
I have same problem.tab cannot power off. Just reboots into cwm.
I was thinking to drain bat. Thanks for sharing that info.
There are a lot of topics about people who broke their devices with TF201's recovery.
Afaik, no one recovered it. Send to Asus.
So the device is bricked then :'(.
Thanks for clearing it up.

RMA..
Guillaume,
Thanks for clarification.
I have read that ASUS wants 700USD for replacing/reflashing the bootloader. That was for the tf201. Any way to nvflash it back to factory? I don't believe that they have to change the MB.
I have no warranty left, but I don't want to be gouged by them either.
Any thoughts, info?
Hi,
I've do the same mistake, but I can use adb.
Do youhave any news about our problem?
Thanks

unable to power off
My issue is that I have the CWM for the tf201. I did the update from the CWM app in Android. Bad idea. So now the tab does not power off s.t. I can get into the power+vol down mode. Adb does not work since I cannot ( don't know how) to make it go into the usb debugging mode. I have tried several things none of which have worked. Still stuck.
I wanted some feedback for a RMA from ASUS, posted it here but sor far no answers.
Not sure if it would really work, but on my Evo, I don't have to completely power off the phone to do the recovery sequence. I can do it during a normal reboot. There is a point just before the device starts booting again where it is technically "off", and if I hold volume down (don't even have to hold power on my Evo; volume down seems to be the only necessary button) starting at this point, the phone will boot into the bootloader.
So, next time the device reboots, just start holding volume down (possibly power also, just in case) at the "off" point.

[Q] Help! Can't reboot into recovery...

Hello everyone. I have Katkiss Kitkat #19 and TWRP recovery 6.something but I can't remember which. Anyway, I use to reboot into recovery by holding down the Volume down, then press Volume up when prompted to get into recovery. Now the power and volume buttons are completely busted. I can't press any of them. And I need to go into recovery to flash the new Rom.
So, here is what I tried:
1. Rom Toolbox. I tried to "Reboot into recovery" option but it just reboots the ddevice.
2. Terminal emulator: su reboot recovery, it says reboot: no such order
3. Tried to hook it to my laptop and use ADB, but no devices attached. I have Windows 8.1 64 bit. I have Android drivers installed and in the device manager it say Asus ADB and it shows Asus in the "safely remove" but I still can't see it in the My computer. I have USB debugging on and it asked me to allow my laptop keys and I agreed. Still, ADB doesn't work.
I don't know what else can I do. I can't go into recovery, bootloader or APX mode without the power and volume buttons. Is there anything i can do, or am I stuck here?
Any help will be greatly appreciated...:crying:
There's a few different apps that let you boot to recovery

When you say the power and volume buttons are completely busted, have you tried taking the plastic bezel off and pressing the micro buttons under the normal silver ones ?

I tried the first one and six from the second link and none of them work. Actually, when I was installing Xposed, I pressed reboot, but it said Reboot: No such tool. I don't know what's going on.
The problem with the power button is that my kid dropped the tablet many times and it got so many dents, so I took of the casing (or whatever it's called0 and then straightened it out, out the buttons in their places and then glued it in place. Now it's really hard to press the power button (the one underneath) but it works. But how can I do that every time I want to power off or reboot into recovery, specially if there is a boot loop. I can't do anything except pressing the power button.
That's why I wanted an easy solution at least to reboot recovery.
May be I should take off the casing one more time and try to fix the power and volume buttons one more time.
I just want to thank you for your super fast reply and taking the time to find those apps.
Thanks a lot...
In the past, while still on stock ROM,I have been using this tool to overcome the missing "reboot to recovery" option in the regular Asus power menu: https://play.google.com/store/apps/details?id=com.transformer.recovery
Now I have tested it on KK #19 and this tool apparently does not reboot the tablet BUT:
when I run this tool and then reboot the tablet normally (with the power menu...) I get into recovery.
So if you are already able to reboot normally through Rom Toolbox you might try to run this one first before rebooting with Rom Toolbox.
NOTE I imagine you are perfectly aware that you are playing with fire here.
In case your tablet gets into a boot-loop while installing the new ROM, you might end up with a useless tablet. Is it really worth the risk?

OK, you did it. You got me scared, so I separated the casing in the power button part and clicked on the original button with a small screwdriver and it worked. Also the volume buttons. Now I don't know what to do. May be the buttons are broken from the inside. I'll try to see if those are sold on ebay or something. If not, I'll try to attach something to them from the underside.
Anyway, I'm really grateful that you made me take this step. I'll fix it tomorrow first thing in the morning. Well, we both know I'm not gonna sleep until I get it fixed, hahaha.
Again, thanks a lot...
