I did a factory reset. It was stuck in "Erasing" for an hour.
1. Restart -> Booted back to Erase mode
2. Bootloader -> Recovery mode -> Booted back to Erase mode
3. Bootloader -> Start -> Booted back to Erase mode
4. USB connection -> no device recognized
5. ???
6. Profit!
Anyone has an idea what to try? Android 6.0. Unlocked, Rooted on Kitkat but didnt modify anything after the update. Bootloader HHZ12k, rev_11
P.S.
Im serious about 5. and 6. Verizon gave me 300 USD for trading in the formerly working phone.
I don't know about the Verizon version of the phone but if it is like the gsm version, you could unlock the bootloader and flash a stock rom.

Hey guys...I'm having an issue.
I did the first step for rooting without the Recovery.img or Root.zip in the Folder.
Now I tried to do the reboot to go on the fastboot for 2nd step (recovery.img) and I get this error on my Windows:
QHSUSB_BULK
I believe it was because I had the phone plugged in. Anyway it was not going to fastboot.
So anyway I tried to do a factory reset too, and now fastboot is working, but I have no idea if it was because the phone was plugged in or because of the factory reset.
So, how do I know if the phone is bootloader unlocked or not after my factory reset?
What should I do?
Repeat Step one to unlock it again or do step 2? Thanks!
Is there any harm in doing fastboot oem unlock again just in case?
ok i believe its all done.
I have the phone rooted, should I keep debugging USB on?
Should I check the "Disable CM Recovery Protection" ?
Whats the best to do the OTA's without bricks or issues?
EDIT: so i tried a couple of things.. Everytime i unlock the bootloader and reboot it starts locked again (as if i never unlocked it), i tried to flash factory image using fastboot but gives me "flash write failure", tried flashing custom recoveries (both cwm and twrp) they flash fine but when i boot into recovery mode the stock recovery appears, so i tired sthg new : booting from the custom recovery without flashing... Cwm boots fine..fails to factory reset (it just gives error and reboots the phone especially when i try anything with the cache partition) so i went to boot twrp.. It takes half an hour to open twrp after its "teamwin" screen... But it helped me as it showed that : system and firmware partitions are working well (format /mount) but cache, persist and data partitions don't (no mounting and error while formating) plus data partition shows zero Mb size.... Basically any change i do either gives an error or dissappears on reboot..... Please helppp! ?

You can boot into recovery and do a factory reset. It'll wipe your data. Or you can unlock the bootloader, it'll wipe your data, and flash the factory image.

As far as i understand unlocking the bootloader would require enabled usb debugging right?

No, you'd don't need usb debugging enabled to unlock the bootloader. You just need fastboot on your pc. Google 15 second adb install xda. That'll setup fastboot. Then boot into your bootloader and from a command window on your pc run the command
fastboot oem unlock

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???
Ive been asked by a friend of mine to fix his nexus 5 that is stuck on a Bootloop, I've opened it up to have a look at the power button and that wasn't the problem, the device has not been rooted, the Bootloader is locked, there is no emergency mode and there is no recovery. I am however able to access fastboot and when I try unlocking via fast boot it does unlock but then requires a full reboot and as I've said before this cannot happen because of the Bootloop.
Any suggestions!?!?!?!
After unlocking the bootloader, does the bootloader relock itself? If it does, the memory chip is damaged and requires a replacement motherboard.
I've had this problem when I corrupted my recovery by using FlashFire and my bootloader was locked. Though I was able to restore my device using Fastboot. I had unlocked my device and instead of flashing the stock recovery when unlocking the bootloader I had flashed the Team Win Recovery Project recovery and when I tried to boot up to TWRP recovery it would stay for a couple of second displaying that it couldn't wipe the data partition and then reboot me back into bootloader mode. I fixed that when trying out the following steps:
1= Download the latest firmware of the device found Here .
2= Boot the device to Fastboot mode (aka Bootloader mode) plug the device in and unlock the bootloader (of coarse confirm when asked by the device).
3= After seeing that the device has stopped wiping data indicated the text "wiping..." in the very bottom of the specifications in the Fastboot Bootloader REBOOT THE DEVICE IN FASTBOOT BOOTLOADER MODE by navigating using Volume buttons to scroll down and highlight the option "Reboot Bootloader" and then pressing the Power button.
4= Using the provided scripts for Windows , Mac and Linux flash the device with the firmware.
VERY IMPORTANT: WHEN YOU SEE THAT IT IS FLASHING "userdata" and after that "cache" HOLD DOWN THE VOLUME DOWN BUTTON THIS WILL FORCE THE DEVICE INTO FASTBOOT BOOTLOADER MODE.
5= When you see that the device is in the Fastboot Bootloader mode scroll down (again using volume buttons) and highlight "Recovery Mode" then boot into Recovery and it should automatically start wiping the ("userdata" partition) Data once more that the bootloader said when it displayed the "wiping..." message after being unlocked.
If not wipe data factory reset the device manually by using the recovery and reboot to the system.
Optional: 6= IF the device has successfully booted up power it back down and lock the bootloader again using the fastboot tool additionally before locking the bootloader you can reset the warranty tamper flags.
This tutorial explains in detail how to flash a firmware to the Nexus 5 and shows how to restore the tamper flags.
I hope that I helped in some way.

Yes after unlocking Bootloader and restarting the device into the Bootloader it relocks and I'm back at square one
The motherboard needs to be changed. I recommend looking for a used Nexus 5 with a smashed screen and a working motherboard as this may easier than trying to find a new motherboard.

Thanks for the suggestion but I've tried this already and it doesn't work because when I unlock the bootloader and reboot into the Bootloader it locks itself again making impossible to flash the system image
Hi Guys!!
I tried my rooting adventures again and found some more facts that can help community to attain stable root.
Whats available--
1. Magisk root.
2. TWRP.
3. V4A
4. Baseband.
Whats not available -
Untethered root with baseband and the ability to get into phone if not having a laptop/pc.
Now some facts-
1. Bootloader is one hell of a thing in this model.
If we unlock it, it would re-lock itself on proper reboot.To keep it unlocked, you need to hard reset the device by pressing power button for 10 seconds.The fun part is - if you boot with unlocked bootloader, it wont allow you to access baseband, and if you try to boot with locked bootloader, dm-verity will come into place and will lock you out.Even more funnier part is, on booting TWRP from bootloader, the bootloader will first unlock itself,boot twrp and then lock it self.(this is the part which helps us to attain tethered root with baseband.)
After many trials, i was able to get a boot image which had Magisk/Insecure adbd/V4A/Non-Encrypted Data partition/no dm verity on system partition.
Now , to get tethered + working baseband root,follow these steps-
First Time Steps.
1.Boot into fastboot mode.
2.fastboot boot twrp.img
3. wipe data partition.
4.reboot to bootloader.
5.fastboot flash boot magisk-boot.img
6.fastboot boot magisk-boot.img
7.enjoy.
When rebooting (for baseband)-
1. Boot into fastboot
2.fastboot boot magisk-boot.img
When rebooting (without baseband)-
1. Boot into fastboot
2.fastboot oem unlock
3. Hard reset by keeping power button pressed.
4. enjoy.
P.S. After every reboot done with baseband enabled, your bootloader will get locked and wont boot into the OS, until and unless, you either unlock the bootloader again / boot into magisk-boot.img from fastboot.
Working on fixing this issue.Will keep posted
