I recently deleted my stock rom and twrp off of my rooted asus 4max. I cant get adb to detect my device cause I'm stuck on the bootloader and fastboot options and cant access developer options to revoke usb debugging authorizations please if anyone can help.
boot into bootloader, flash recovery, ex. fastboot flash recovery recovery.img, after that boot into recovery and flash update package for your phone.

After messing around with my shield last night and not being able to get root access on cm12. I tried to reinstall one of the ota updates from a while back. Now I am bootlooping and when I try to boot into CWM it looks to be corrupted and doesn't load. I cant use ADB because usb debugging is no longer active. Does anybody have any suggestions to re-install recovery or somehow enable debugging or am I dead in the water here? Any help would be greatly appreciated
Is your bootloader unlocked?
Can you get into fastboot mode?
HW method:
Turn off the device
Press and hold "Back"+"Home"+"SHIELD" buttons till device boots

If you can get into fastboot mode and your bootloader is unlocked, you can use a command like "fastboot boot recovery.img" to have the device boot a recovery.img from your computer without flashing anything.
If you can get into fastboot mode, but your bootloader isn't unlocked you could try unlocking your bootloader, but this will wipe your data - so only try this if you don't have anything important saved. The command is "fastboot oem unlock".

The bootloader is unlocked Whenever I try fastboot mode the device is not recognized because USB debugging is disabled .
Update: Fixed
I don't have access to in phone settings
I don't have root
I don't have boot loader unlocked
I can sideload with Adb !
Please can some one help me get my handeset back working

I've android PumpKinx 10.1 tablet with 5.1 Lollipop android os.
I did take backup of its stock recovery image.
Since there is no custom recovery image for this device I tried to flash it with twrp recovery image. But after running below command, device goes into bootloop. I've tried many methods but no success.
fastboot flash:raw boot twrp.img
Any help would be highly appreciated. Thanks in advance.
maybe u have locked bootloader. First turn on oem unlock in developer options, then reboot in bootloader and type
Code:
fastboot oem unlock
Then confirm acion in the tablet whit volume up, then the bootloader now is unlocked.
Note: The tablet get soft reset. Make backup first.
Then try flash the recovery

Do you understand boot loop or not? First of all fastboot is already unlocked otherwise how I will be able to run above command and since my device is in boot loop then how can I go to developer option?

Just send them an email asking for stock firmware with flash tool, along with the purchase bill..
Or if it still has warranty, just go to the service center and say something like you over-charged the phone a complete night & since then it's not working and claim warranty..
Have you tried to wipe the cache partition or even factory reset???
I was installed with Twrp and had rooted my oneplus 3.
I unticked root access in supersu.
Booted to bootloader and typed on my pc in command prompt ,"Fastboot oem lock"
This gave a confirmation on my device,I confirmed locking.
And after that my device did not booted up.I managed to get in bootloader again as I was not even able to open the recovery and unlocked the bootloader once again by this my device booted up.
I flashed stock recovery and repeated the relocking process,this time I was able to open recovery also but no able to boot up.
I again unlocked the bootloader and installed twrp back turned my device up.
Then I unchecked oem unlocking under developer options.
Relocked the bootloader once again.
And now I am stuck at bootloader,not able to unlock it even this time as I turned off oem unlocking.
Now I can only open bootloader.
Please help!

OEM locking a bootloader on a phone that was rooted is a big mistake.
You'll need to flash stock recovery, then flash the stock ROM via adb sideload.
Can be done with this tool http://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Thanks for reply

I can't access it as I am installed with TWRP Recovery as it is also not starting.
Hello, I have a vanilla Pixel 2 which corrupted itself and will not boot. It boots to recovery mode, but Bootloader is locked. I have not done a factory reset, and am attempting to recover the files. Fastboot mode works but will not allow temporary boot or unlocking of bootloader. I can access adb but only in sideload mode. OTA images successfully sideload but it still will not boot... After hours of scouring google I'm stumped. Any thoughts or suggestions welcome.
Hint: Add Pixel 2 to this thread's title thus mainly owners of such a phone get addressed.

I see that u want to keep your files but sorry to say this but your gonna have to do a factory reset because their is no other way to fix this
To do this boot into recovery mode and perform a factory reset
If u can't boot into recovery mode u probably have to unlock bootloader than install twrp
But that's probably only gonna work if u enabled oem unlock and enabled usb debugger before your device got bricked
Because if u try to unlock the bootloader with oem unlock and usb debugger disenable your gonna receive error when trying to unlock bootloader
Try to start in recovery mode. Otherwise only restore is the option.
You can start mobile in fastboot mode. You can back up mobile.
adb backup -all

On Android-side bootloader initializes ADB and mounts partitions. Hence check whether phone is accessible via ADB:
Code:
adb reboot
adb devices
If it is, and partitions got mounted, then you can fetch the user-data you are interested in by means of adb pull method.
