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.
Ok so, this isn't my first time flashing and returning to stock with phones, just the worst. Any help is appreciated.
I unlocked the bootloader, installed TWRP and tried to flash a few ROMS which were not working great so I went to go back to stock and then the **** show happened. Its the LO4 Model. I flashed stock recovery, Relocked the bootloader and tried the Force Flash Update method. Well now the phone is stuck in a boot loop(Cant power it down), cant boot to erecovery/ recovery -- I can get to fast boot mode but the FRP is locked so I can not do anything all commands fail with an error.
Any thoughts? I just need to get it back to stock OR a working ROM- I plan on selling this phone and My wife (it was her phone) has upgraded to a Galaxy S9. If I cant get it to work, I will post it on swappa as is for a cheap price
Thanks!
Same Issue
I did the same thing, however when in fastboot type fastboot oem unlock (put the code here) and this will unlock your bootloader. I did this I even managed to flash the stock system cust recovery and boot, but it doesnt boot into recovory, erecover, or even download mode to download the software from the sd card. Any ideas?
I tried that fastboot code and I get an error because of the FRP lock
I deleted my bootloader. Whatever rom I flash it's just went into bootloop and when it boot the second time it boot into Huawei erecovery. My model is mha L29 cc636. I used to run on Android 8.0. Plzzz help
Try typing "fastboot oem relock (your phone's unlock code)" but this method will factory reset your device.

Fastboot won't work since I deleted my bootloader. I couldn't get into fastboot mode.
hmm.....I didn't;t know you could delete the bootloader.
If your phone still goes to eRecovery, then you couldn't have deleted your bootloader. (Fastboot is the stage 2 boot loader, which loads the various other partitions for startup, boot or kernel + ramdisk for normal, recovery or kernel + recovery_ramdisk for recovery, and erecovery or erecovery_kernel + erecovery_ramdisk for eRecovery.)
In any case:
Power off
Hold volume down while plugging into computer.
That should start up fastboot.

I believe that relock is impossible and but to make the device recovery to installed status of stock rom keeping with unlock bootloader.
Please see my post. May make it help or not.
When I try to burn rom with TWRP, img burns but it doesn't start and zip gives an error and cannot burn.
When I first burned custom ROM (unofficial AEX), it did not start, so when I deleted the data from TWRP, it seems that I deleted things that should not be erased, so even if I burn it from the zip file, with the error message in the image below I...

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.
