[Q] oem unlock resets to locked after reboot - issue - Nexus 4 Q&A, Help & Troubleshooting

Hi Everyone,
I have some experience of unlocking, rooting , flashing custom roms etc. but this issue has me really stumped and searching for the past couple of hours only led me to 1thread with a similar issue and no solutions. So here it is:
stock (4.3) N4 stuck in boot loop.
Fastboot oem unlock will not survive reboots, so I am unable to flash stock image back on my device.
Please Help with a solution to get this phone working again!
History:
Last night I turned on my wife's N4 (Android 4.3 stock) and put it on charge and walked away. This morning I found it is stuck on the "X" boot screen and red hot. I powered down, let it cool for 1/2 hour and then fully charged it (while off).
It will no longer boot, sticking on the "X" screen.
Booting into fastboot and choosing recovery leads me to android with red "!".
This phone has never been rooted, unlocked, custom recovery or custom ROM. ( I have however done all of this to my other N4)
Attempts:
Decided to wipe it and reisntall stock 4.3, lots of errors because it is locked.
So 1st step is to unlock, however whenever I do fastboot oem unlock I get the prompt about unlock and YES/ NO. I select YES and it successful erases and report LOCK STATE - UNLOCKED in red.
I reboot the phone into fastboot and LOCK STATE - ENABLED in green. Now stuck on what to do next.
(Secure boot - enabled).
Many thanks in advance.

Go into the stock recovery and do a factory reset. Go into the bootloader, choose Recovery Mode. When the dead android/red triangle comes up, hold power and tap volume up. Then select wipe data/factory reset.

Sorry, I re-read and followed your instructions :good:. I went pass the red "!" and did the wipe data / factory reset.
I rebooted into fastboot and issued
Code:
fastboot oem unlock
LOCK STATE- unlocked
I then rebooted again into fastboot
LOCK STATE- enabled :crying:
update:
I see errors after the wipe cache (successful)
E:failed to mount / cache (Invalid argument)
then lots of errors of failure to mount other cache sub directories and flies.

the android with the red "!" IS the stock recovery.

Summary so far:
N4 (stock) stuck at "X" screen.
booting into recovery and doing factory wipe + reset formats ok (but results in errors mounting cache)
"fastboot oem unlock" will unlock the phone for next reboot (google logo + unlock symbol) where it will then hang.
Subsequent reboots the device is locked (hang at Google screen withOUT unlock symbol).
Booting into Fastboot the device is locked again.
More help gratefully received.

it sounds like you might have an issue with the storage. at least when the storage goes bad, it follows the same symptoms. usually when the storage goes, people just find their device on X. if unlocking the device results to going back to locked after a reboot, it sounds like its actually not clearing the storage of the device, which would happen if the storage went back.

Thank you. I was reaching the same conclusion of a hardware issue. I'll arrange a warranty repair. I have 3 days left on the Warranty....

Stuck on google logo

Hey guys
i just wiped all my data and tried to reboot my nexus, but now it's been stuck on the google logo for ages...
trying to flash to stock + unroot with nexus toolkit doesn't work, any way to unbrick it?
please help...
do you have fastboot driver installed?
Step 1: Power down your Nexus 4 (hold the power button until it shuts off) before rebooting into fastboot mode. You can do this by holding down the the Volume Down and Power buttons simultaneously.
Step 2: Connect your device to your computer. Open up a terminal or command prompt, and navigate to the folder containing the fastboot program.
Step 3: Type fastboot devices into the command line, and you should then see your device’s ID, which means fastboot is setup correctly.
now go back to Nexus 4 toolkit. Flash back to stock.

Thanks simms, i managed to get into fast boot between the reboots, and I flashed the rom and gapps.
Damn it scared me even more then the red light issue that happened to me last month.

not booting after flashing something or modding something is the easiest of all to fix, just reflash the rom(gapps and kernel too if need be), no need to wipe anything. since i test all the trinity kernels before any get released, and pre-kernels, i get many that dont boot my device or bootloop(among some other funky behaviors), reflashing a good kernel always works
I left my phone for a few minutes, and when I picked it up it was bootlooped again, and i had to use fastboot again. What should I do now? Maybe a factory reset would help me. I don't want more unexpected bootloops. :/

Try another rom. You might have downloaded corrupted zips. Also, make sure you flash the things you need first. Eg, flash rom and gapps. Don't restore anything if you're using titanium backup. Try restarting the phone, see if it gets into a bootloop. If it doesn't, then try restoring apps from TB. (if you use TB.)
Hi!
I´ve got a big problem. Today i flashed the new PA version, but it seems that the download had some issue. I could install it but after a while, I wanted to reboot the phone and it got stuck at the Google logo. I can only access fastboot mode and recovery.
So the problem is, i made a full wipe, so i have no rom on the sdcard anymore. Also I am now able to enable the debbuging mode. I tried every toolkit i couzld find, but everyone needs debugging mode enabled. windows doesnt recognize the phone ( it says unkown device). So i tried to install the adb drivers, but nothing happens.
i wanted to try to push a rom with adb on the phone but it says no device found. i am such a noob, i hope some can help me.
thx

same problem here and cant find solution ...
I had the same issue. when you press to reset button when the phone boots it should reboot and for a short time go to recovery and try to write some commands, right? if it does like mine did then what i did to fix it was boot up the phone and wait for the page saying encryption unsuccesful to popup and on the computer have the adb reboot recovery ready to go so when you press the reset button and the recovery menu pops up press enter on the computer before it goes away and it should send you to the regular recovery menu. from there you should go back to wipe and press the format data button where you have to type yes to erase everything. let me know how it went.
you will have to reflash the supersu but it should now be working like it should
Flash the latest su and your fine.

Make sure your on charging mode and you have adb debug enabled
send the adb reboot recovery command as soon as the twrp connects to the computer. as soon as you hear it connect to the computer it should work if your drivers are working.

What screen are you stuck in? Do you have adb up and running?
Same as before Encryption unsuccessful. I was able to do the trick, got into two and wiped data. Then rebooted to system and it went right back to that screen. I've tried 100 times or so to get back into twrp with no luck. I hear the computer recognize the device when it goes into twrp for 2 seconds after you click reset. Not sure if that means add is up and running or not.

Had the same problem and could not for the life of me do the adb thing. Someone here stated something that I thought I'd try: Press volume down while plugging in the phone to get into fastboot. In a command window issue "fastboot oem lock" (this will relock the boot) > Let the phone reset and you'll see the "Phone corrupt message" > Plug the phone in again to do a fastboot and issue "fastboot oem unlock" > Take the battery out let the phone boot and BAM-E WHAM success!
btw. I followed the steps here to do the whole root thing with Android . how (google "how to root the v20")
I think the "data" wipe did this and according to this site it's not a necessary step so skip it.
This option works!

I go my T-mobile LG V20 H918 on 11/23/16 and sure enough, I followed the same thread as listed above where it added the step of "data wipe" crap. I was caught in a bootloop, where phone kept bootlooping back to the "reset to factory." The other method of entering the adb command at the right time was more frustrating than anything. (I never got it to work). I spent all day yesterday trying to get this phone working. I re-read (x30) the above thread and on the first attempt it worked. I did not get the "Phone Corrupt Message," but I went ahead and entered the "fastboot oem unlock" and the F#$king phone finally reboot to the setup initial screen. It wiped everything, but having a phone working rather than a nice $800 paperweight, I wanted to kiss SkyHusky for sharing this simple method. YOU ARE AWESOME!!!!
By the way, since I am a glutton for punishment, I followed the steps to root again. After flashing the SuperUser, I rebooted to System. I was at the initial setup screen. My phone is rooted, has TWRP, and SuperUser! As soon as I got the phone working, I went back to TWRP and made a BACKUP!!!!
It is amazing that every time I f-up a phone, I can always come to XDA and get a solution. THANKS GUYS!

No problem!! Also I forgot to add I only rooted afterward and didn't try to install a ROM or anything. I would think you risk danger with some ROMs without that decryption thing turned off. So maybe in the short future there will be better fixes.

Stuck on bootloader

A couple days ago, my volume buttons were not working so I thought a quick restart would fix it. But when I restarted it, it went into bootloader. Its stuck on the 'Restart bootloader' option and I can't select it with my power button nor can I select other options with my volume keys. I try and hold down the power button and it restarts into bootloader again. I booted into recovery and tried to restore it with a nandroid I made that had everything stock but that didn't work. I also did a factory reset, but every time I try to boot into system it goes to bootloader instead. The only problem I can think of was that I held my phone when my hands were wet so maybe water went inside? I'm tempted to get rice to get the water out but I want to be certain that this is the result of water damage. If it helps, I had TWRP and a very early version of Lineage OS on the device before it happened.

Hi... How did you manage to boot into recovery without the volume rocker?
Have you tried a simple:
fastboot format cache
fastboot format userdata
fastboot reboot
From bootloader?
Is your bootloader unlocked? If yes, try loading a factory image from Google if none of the above work.

I used 'fastboot boot recovery.img' to get to recovery. I tried to format the cache and userdata again, but still didn't normally boot. I also tried flashing the stock images from Google's website but still it won't boot.

I never seen this before. If you type fastboot reboot, it reboots directly into bootloader, right? I first thought avout the bootloop issue many currently report. But if you can boot a recovery.img or if your phone only reboot into bootloader, I think this scenario can be excluded.
Hmm you said you touched you phone with your hand wet?!
Could it be the moisture that oxidized the volume down contact inside of the phone? I don't have another idea. Wait for other people to chime in. Hopefully it's another (easy to solve) issue which I am unaware of.
Good luck.

No error came up when I flashed it and holding power button at bootloader restarts the phone back into bootloader. I might just stick it into some rice and use my old Nexus for now unless another solution presents itself.

Sorry for late reply, but I did manage to get if fixed. I sent it back to my phone company to get fixed since it was still under warranty (even though its rooted with unlocked bootloader). Though, they didn't really tell me what went wrong. I assumed it was a hardware problem (a piece of rice was stuck in the speaker hole and was impossible to remove but was gone when I got the phone back).

You can select factory reset by pressing the volume button . Factory reset will come up. Select by pressing power button and press again to wipe.

you are not alone...?
Same issue on one I have my hands on. This could get interesting.
From fastboot can anything be pushed/flashed like a previous actually functional firmware? Is there other specific software to do so? Only got my hands on the defective non functional device today but I'm planning and scheming a fix if possible.
One thing is really interesting. Why only after this update???? Why not after update from 6 to 7 then 7 to 7.1 and after 7.1 to 8.0. I think Google or Huawei is cheating us and forcing us to buy Google pixel.
I also have this issue (I'm using a nexus 5x, but this thread is the closest to my issue I've found), but it came incrementally. First, I started getting reboots every 20m or so, while doing normal phone things (reading, mostly). Then it started getting into bootloops that were 2-3 boots long, and would then work normally for the 20m mentioned above. I tried a factory reset, but it just got worse, and now either reboots on the Google logo or during the Android animation. My fastboot menu only has the regular "Start" as green. The only other options are Restart Bootloader, in red, and Recovery mode, also in red. Power off is there, obviously, but that's it. It started happening yesterday, and worsened to its current point within only a few hours.
Well. I have just joined the club. What is going on with that?
Happened to me today and I was using the latest build of SuperXE 6P.
Guys! lol
1. Dev options in ROM is same old. Settings/about and tap build 10 times to see count down to developer. Back to settings. In there for OEM unlock
2. Factory reset can be done any number of ways.
a. In ROM. Settings/backup and reset/factory reset.
b. From anywhere, hold power+volume down until you see the bootloader. There are 2 possible screens in there. One of them has factory reset. Beware! From here it will likely wipe your sdcard!
c. From recovery. You can get there from bootloader. You can also flash an up to date recovery image from bootloader.
The rest of your recovery process should be provided by the ROM thread by which you will get your choice of ROM.
Make sure you have access to a PC with adb. You will likely need to flash a vendor image
My device is only recognized in fastboot mode. No ADB, no recovery. Tried to uninstall and manually install latest USB drivers, it didn't work. My Nexus is now just stucked in a bootloop. I even tried to flash factory images to no avail. Really don't know what to do...
FYI I have no screen in bootloader allowing me to factory reset: only Start/Reboot/Reboot bootloader/Barcodes, as others stated above.

HELP! OnePlus 6T Black Screen - Won't Boot

I successfully rooted the device and until recently I wanted to unroot the device, so I uninstalled Magisk.
However, after doing so my device rebooted into a black screen and the only response I got was a vibration when I tap the right side/edge of the screen or press the power button.
I tried pressing the Power button + Volume +/-, and was able to enter recovery and fast boot mode. However, I tried wiping cache, resetting, and formatting, my phone would still reboot into the same state.
When this problem occurred I had 30% battery and I also tried MSMDownloadTool for 6T, but my computer simply does not recognize the device. My device is only two weeks old.
Any help would be appreciated.

Can you tell me how do you do that? Because I tried connecting my device I couldn't get my computer to recognize it. All I see in Device Manager was: LeMobile Android Device or something.
Thanks!
