So two days ago my phone started to act up, first it rebooted while I was in the Play Store for no reason then when it rebooted it kept saying "Lockscreen has stopped working" and wouldn't stop doing that. I tried pulling up a backup I made on TWRP (Rooted) but it just did the same thing and wouldn't let me open the settings app when I had the chance. Then I did a Factory Reset but it just made things worse, it booted it up but when I had to choose a language it rebooted and kept doing it. After that I did a full wipe and went I tried to reboot it said I had no OS and now I'm stuck with just TWRP. And I have just found out earlier today that my bootloader is locked. So what could I possibly do? Thank you in advance for those who are able to help.

Yes I have and It does not do anything, I tried unlocking it manually and with a toolkit but no results. Also I have pushed CM11s to the phone and tried to flash it but no luck.

I was stuck in the same situation, unlocking via fastboot just rebooted and did nothing, however I managed to unlock the bootloader by flashing this in recovery...

Urgent help reqd
randomly my nexus 5 restarted
google came on screen and now only those four animated circles are showing up and the phone doesnt go further
went in bootloader but cant wipe cache, cant format, or anything else from there.
usb debuggng must be off as far as i remember
trying to flash through sdk manager. have downloaded image. but stops at "waiting for device" in cmd and it doesnt go any further than that. even tried doing it manually through cmd.
when the phone is connected it is showing the drivers but it isnt installng and can see the yellow exclamation.
manually downloaded the drivers and tried installing manually but shows drivers are up to date.
uninstalled driver and reinstalled but same issue. it is connected to usb 2.0.
now how do i get it to work?
I have tried all the options i could search for on this forum but none of them solved my issue.
Is the bootloader unlocked?
How do i check that?
Ok got it
It is locked
How do i unlock?
I checked some unlocking bootloader threads but they all require usb debugging to be on.
My phone is not starting at all so i cannot do that
How do i go about it now
Tried nexus root toolkit. It isnt detecting the device.
Unlocking will wipe you device.
Google themselves have a guide on how to flash, not sure why you are using toolkits.
Also, you will wipe your device, if you haven't already. Make sure you have the right drivers, make sure you get the device to come up under "fastboot devices"
Already tried all methods mentioned by google or xda.
If you read my initial post my phone is not getting detected as well but shows installing drivers when connected but the installation fails.
Manually install the correct drivers.
Tried that but i get the error that you already have latest drivers. But its not detecting the phone
Try removing the drivers and reinstalling
Also, try different USB ports and cables.
Did all of that a number of times. Still no luck
Other phones are getting connected and detected just fine.

Hi all, i have a similar problem
this morning my n5 boots into "optimizing apps", but stops when reach around 15/20 apps and reboot (3 or 4 times)...
Now, only keeps in android animation like useruser12.
I can see my data in TWRP, battery 95%...
I wipe cache/dalvik... nothing
I reflash the kernel (ElementalX 6.17), still nothing
Any ideas?
PS: latest news. After make a backup, I made a factory reset and restore a system-boot-cache partition from old backup. Now the phone boots but i hate lose all my data xD. I want try to solve my problem using my "corrupted" backup for avoid losing data. If that fails, I can always restore this functional backup. Any ideas again?
Used the nexus root toolkit.managed to unlock bootloader but immediately the device reboots and goes into the bootloop again.
Tried the flash stock + unroot function as well which detected my factory image and everything went smooth till it came back to unlocking the bootloader and rebooting the device after that and again went into the bootloop
Though i have installed the drivers, on reboot windows 7 automatically starts installing the mtp usb device driver but fails. Manually downloaded the drivers and installed as well.
Still its not worked and whatever i do it comes back and get stuck at the bootloop.
Any expert can give a solution? Thanks
After unlocking the bootloader, does the bootloader relock when the phone is rebooted? If it does, the memory chip is defective.
Phone doesnt reboot completely.goes into a loop after the google logo and doesnt go further.
If i switch off the phone midway here without it booting up and then restart the bootloader then its locked again.
But what i read was that the process of complete reboot needs to finish and i need to turn on usb debugging. So is it because of that the bootloader locks again?
Anyways, this what im facing

Lucky that you could do a factory reset. I wasnt even able to do that from the bootloader.

Sorry, i did it via TWRP.
If the bootloader relocks itself upon reboot, it's the memory chip that is damaged.
Hello Guys,
I'm back again (I posted about this issue about 6-9 months ago, a couple users tried their best to help me with it, since than I haven't had any time to fix this issue).
History:
1. Brand new FRD-L14, bought the phone, used it for 1/2 day, fell, cracked screen, replaced it.
2. The phone worked there after, but the OS read "NRM-Test Keys", anyways since I had TWRP installed at that time, tried several different roll backs and such to install a full OS, never worked
3. I did encounter a problem where the fastboot screen would read "PHone Unlocked", but "FRP Locked", at which time I was unable to install anything the error when going through Adb/Fastboot would be "Error: Command No Allowed", a experienced user here did fix it remotely for me, no idea how, but anyways it worked, so back to #2
4. Now the phone has FRP Locked again. So I can get into fastboot, and stock recovery (which doesn't work, states device is unsupported), cannot instal TWRP as FRP is locked
What I need help with is to get rid of this dam FRP Locked issue. I don't understand why it keeps coming back despite me not logging in/putting in credentials when I install the OS.
As I am in the US, Huawei has no authorized repair centers. What a waste!
Any help or suggestions are welcome. Thanks.

Can you get to download mode for the sd card firmware update?
Hi, I was trying to update the phone by OTA with an official firmaware, but something went wrong and now it goes in bootloop with the MI logo that keeps appearing on the screen.
I want to flash a clean firmaware to solve this thing, but without unlocking the bootloader it seems impossible.
So now i'm trying to unlock the bootloader, but using the Mi Unlock Tool I need to give some permission that I can't, because I can't turn the phone on!
It asks me to add my account on the phone (that was wiped during those steps)
How to solve this?!
Just to complete this thread. Now the phone turned on, only God knows how.
I did nothing, nor charging, it just turned on when I press the power button. That's a miracle.
But, the question is still there... If this happens again, how can I solve it?
That's a common problem with the MIUI 11 update, the phone takes too much time to charge system files while updating, and that results in a bootloop that isn't really a bootloop, bootloader tries to recover the phone and solves the problem automatically but requires to reboot some times, after that the phone seems to work normally but is recommended to do unlock process with mi unlock after successful update, and after that do a clean flash with fastboot method using mi flash tool
Hi everyone last night i decided to root my ohone. I have had it for a while but for some reason hadn't got round to doing it.
I followed all the instructions firstly unlocking bootloader, TWRP then installing no verity and magisk etc and every looked to be good phone starts up with the the your device has been unlocked message and something about bad id key but then would start like normal and set about installing all my apps etc again for the phone to be back to how it was just rooted.
However tonight i restarted my phone and when it's went to start up it throws me into the fast loader screen wtih your device didnt stat up successfully use the software repair assistant on computer to repair your device.
I had only been installing my usual apps/ new luancher etc... however the only thing i think that could have caused an issue was i checked for an android version update and it found i already had the most up to date one so nothing was downloaded but possibly just checking has caused an issue ?
Any help with this would be appreciated.
I can still boot into team win recovery mode but was hoping as i've now installed everything a new... i could resolve this without another fresh install if possible ?
Thanks
