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.

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.
Sent from my GT-I9100 using XDA

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
Midyr

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] Stuck on boot screen

Hi, my Shield is stuck on its boot screen, the one with the green shield and the mist whatever. I've tried restarting it but nothing is happening. I don't even know what caused it, I just picked it up and opened it and it was on its boot screen. Last thing I knew before it, it was working perfectly fine. I don't have recovery installed... It is rooted but I doubt that would cause this... any help?

That's happened to me before.have you tried leaving it off for a few minutes and then restarting it. maybe try while its on the charger.If that doesn't solve it I would attempt to boot into stock recovery and perform a FDR. either way someone will get you back up and running again.

I left it off all night and after I turned it on again this morning it's still stuck. I've tried it both on and off the charger, won't work either way.

That's supposed to happen.you need to press home and back I believe to get the menu to pop up. might not be those buttons but there is a button combination to get it to popup.

Well yes, I hold home and back when I turn it on, and it brings me to a screen with these options:
Continue
Restart Bootloader
Recovery mode
Reboot
Poweroff
Selecting "Recovery mode" just brings me to a screen that says "no command". I tried doing various button commands to try and make something happen, but nothing happens.

I realize that but Keep trying there's a two button combo to get the RECOVERY MENU to show up. If you can't get it I'll go get my shield and flash the stock recovery so i can figure it out.

Nvidia Shield Portable
My sons Shield Portable is stuck on the screen that has a dead looking Android that says no command after trying to install a factory update. I have tried holding down the power button the home button and back button to try and recover. The recovery mode did nothing. The restart bootloader did nothing. I have pressed the power button and the home button at same time to try and wipe the data. I did wipe and hit the factory reset once I did that I hit reboot. when it started back up it still says the same thing. Please help

same problem
I have the same problem if anyone knows the combo to go straight into recovery I would really appreciate it.

Bootloader Unlock keeps on looping and i cant get into fastboot

Hey guys I am in a frustrating situation right now, but i cant for some reason undo the loop whenever i turn on my phone it keeps popping up the warning and loops by powering off my phone and going back to that warning screen. Does anyone know how to fix this by any chance? I only unlocked my bootloader and flashed twrp and its driving me insane that whenever i press the volume down and power button it does this so i cant even enter the fastboot mode.

Pixel Stuck in Bootloop, ADB Unauthorized, Bootloader Unlocked

Hello, I recently came on a pixel phone to build and use lineageOS on. Upon rebuilding, I believe I performed adb sync wrong the device and damaged system. After that, my adb keys became unauthorized and I am unable to access the bootloader menu(I press power and volume, but phone boots into Bootloop). I tried the steps to get to bootloader menu, but the phone doesn't power completely off, and when I press the power button it gives me the launch screen saying press power to pause/continue boot, not allowing me to go into bootloader
My bootloop goes like this: Bootloader integrity screen(bootloader unlocked, cannot be verified) --> Google loading screen --> Android recovery. This shows 2 options with the message, "Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device". The two options are to try again or data reset.
I press try again, and the same bootloop ensues, sometimes getting to lineage loading logo, but then back to the same recovery error regardless. If I press the buttons(power and vol up), to go into recovery, it just shows an android with a warning sign above it, giving a message saying "Error!" on the bottom. My adb on the computer shows as unauthorized, so I don't know how I can fix this. Google has said the warranty is expired and cannot do anything to help. Ideas to fix? Thanks for help in advance!

Use power and volume down (not up) to go into Fastboot mode. Then flash the stock images

I tried that, but whenever I press any button, the phone is never turning completely off unless it dies. Even after that, it goes to the screen showing the secure boot integrity(Press power to continue/stop boot)
How can I completely shut off the device and restart it? And if system is messed up, will that leave my bootloader intact(I'm assuming so as boot is a different partition?)

Does holding down the power button for 5-10 seconds turn it off? Or if you do that does it appear to turn off and then restart?
If that fails to turn it off, try just holding power and volume down for 5 seconds, and if the screen flashes (goes off and then on) let go of the power button but keep holding volume down and hopefully it goes into Fastboot.
That should work unless you have a dodgy power or volume button. The bootloader is completely separate to the boot partition, and the fact that it's doing anything at all suggests that it's still functioning.
Only other option I can think of is trying ADB commands when it's in recovery mode, e.g. adb reboot bootloader. However, if you have the stock recovery, that may not work.

Thank You!!! It didn't work in the bootloop, so I had to let the phone drain its battery and shut itself off, then I was able to enter the bootloader and reinstall lineage. Thanks so much!

Is ur bootloader unlocked? If so, use twrp to perform a full wipe and install from twrp as well. Of you can't access trwp, and are in a bootloop, do the same thing I did: let the phone lose all it's battery, so it's outta the loop, connect the phone to a charger, then hold power and volume down. This should get you into bootloader mode where you can then use fastboot to flash twrp.

My bootloader is unlocked but phone not detected on pc only black screen nothing else.... Red light flashes whenever connect to charger

Possible or Not? Factory reset bricked Pixel 2.

I've spent hours searching and cannot find a definite answer to my question. I see others have asked HOW to fix this issue, I just want to know if it is possible.
Is it possible to factory reset my device or not?
Bootloader is NOT UNLOCKED, and I am stuck on bootloader screen.
"Bootlinux Failed: Not started" when trying recovery mode.
"Slot Unbootable: Load Error" when trying to start.
My device is obviously not found under adb devices as it is locked, but does show up in fastboot devices.
My computer does recognize the android device as well.
Is it possible to factory reset my device or not?
Is there any way to flash a custom ROM and get it operational?

I'd say you're out of luck, I've had the slot unbootable error/ authload error and both usually require re flashing the bootloader, radio, boot.img or a full factory image restore via flash-all to restore via an unlocked BL. I haven't seen any other methods available for the walleye with a locked bootloader I can offer either.

Surely Google or some super nerd would know how? But I think I am also out of luck.
Thanks though.

Hi! I don't know if could helps, but did you try to sideload full OTA through recovery mode? This should be go with locked BL too, but I am not sure if you have to have enable usb debuging...

Hey Somin,
I haven't fully looked into that option yet, started to give up. But I can't access recovery mode or even get out of bootloader, and usb debugging is not enabled, oem is locked.
If you have any further information or ideas I would be really keen to hear.
Thanks,

I do appreciate your help, but as I just mentioned, I am stuck in bootloader screen and get errors when trying to access recovery, download, start or any other option. Obviously using the hard reset only brings me to bootloader where I am stuck.

Hi! No Shut down your phone and try "the game" with power button and vol+ btn... I didn't find any tutorial and it is slightly lottery, but you could get directly to recovery mode if you will press this btns in correct way:
- try to hold them for long time
- try to hold power btn and quick pushing vol+
If you will get to "no command" screen, press again pwr+vol up and you should be in recovery mode. Good luck

Interesting, I get the same error message as I do when I try to enter Download Mode. So this is different than the power and volume down, and different than just restarting it.
So far I just keep getting back to bootloader screen saying operation denied. But might keep trying it here and there haha.
Thanks for your help.

I had the same problem. I was able to solve it by selecting the download mode in the bootloader. There was an error message. Then I fastboot flashing unlock on the console. Then the bootloader is unlocked. No idea why this worked.
Maybe this will help someone who encountered the same problem.
