[Q] Says Bootloader is locked when not. Bricked Nexus 4? - Nexus 4 Q&A, Help & Troubleshooting

Around a week ago everything was force closing on my N4 so I decided to reboot it, when I did it got stuck in boot loops. Because of this I went to wipe the data and cache so I could flash a Rom but when I did all my data from my SD partition had disappeared. This has happened to me before and the way I solved it last time was to unroot and flash back to stock using the Nexus 4 toolkit. However when I went to do that this time it said my boot loader was locked so I couldn't complete the task. So then I unlocked the bootloader which apparently is successful but when I refresh the bootloader it seems to be locked again. Over the last week I have tried sideloading zips, force flashing, unrooting, unlocking the bootloader and all this on both a mac and windows toolkit.
When researching this problem I only could find one thread which resembled my problem on xda however it was about the Nexus 7 and the person ended up sending it back to Asus. Would be great if someone good respond, thanks!
(Also my device is a Rooted UK 16gb if that helps)

It sounds like your emmc flash memory is bad. Not being able to lock or unlock the bootloader is a sign of that. You should warranty the device.

I agree. I faced a similar problem on my Optimus 2X. It started with occasional bootloops, and last week it got to the point where it was boot-looping after every boot w/ force closes, missing data, and e2fsck did nothing, because the fixed errors came back within hours. Definitely sounds like your memory chip has called it quits.

[Q] Boot loop issue - at&t Android 2.3.6

Hi,
I have dropped my phone few weeks back and cracked the screen. Still it was in working condition and every thing seemed working fine. But during the last few weeks my phone has received the OTA updates and now it is on Android 2.3.6. Now my phone is rebooting on it own. If I try to reboot it never reboots. When I try to reboot in 'Android Reboot with No BP' option, it reboots and every thing seems working fine but in few minutes it starts rebooting again on its own. Not sure when I dropped the phone it got some hardware damage or the OTA updates causing this reboot issue.
When I tried to boot up using 'Boot Android (no BP)' option it at least boots up and shows me Motoblur log in screen but again with in few seconds it goes back to boot up mode. Some times it stays for 5 to 10 minutes but never stays there more than 10 minutes and it goes back to boot loop.
I have unlocked my Atrix using Automatic boot loader tool. Did not help. Tried to flash with Motorola .SBF files both 2.3.4 and 2.3.6, no luck either. Did the factory reset, wipe out the cache etc....no luck.
I have even tried to install custom ROM (NottachTrix 4G), that didn't help either.
I am thinking it might have caused by Android 2.3.6 updates. So I want to try to flash it with a custom ROM which is built on 2.3.4 or lower but afraid to do that thinking I might hard brick my phone.
Any help is greatly appreciated.
Thanks,

Well, unfortunately with the screen cracked, you can't return to Motorola. I had a goof with my Atrix when I first got it because I accidentally did a SBF flash to the wrong version and it bricked the phone and fried the motherboard and Motorola replaced it because I said the Gingerbread update messed it up. Ha.
Anyways, since returning to Moto is not an option for you, I would just go ahead and try to install a custom ROM, maybe try Neutrino ROM 2.2 or 2.5?
Do you have ROMRacer Recovery or CWM Recovery installed? Will it let you get into it? If so, put a custom ROM on your SD card, do a wipe data and cache and install it.
I'm no expert, but I have noticed no one else replied and just trying to help.
Hope all works out for you!
Boot loop issue - at&t Android 2.3.6
Thanks andreww88 for your reply. I read in one of the forums that once the phone is updated with 2.3.6 don't try to go back to older versions especially lower than 2.3.4. That would make the phone to be hard bricked. That is why I didn't try any other ROM other than NottachTrix 4G because it is built on 2.3.6. I could be wrong. That is why I need some guidance to try any other custom ROM.
i had the same issue. What i did was get the Atrix Fastool and whipe the phone. Then i extracted the sbf for 141 and then flashed 59 60 and 61 smg files from fastboot. After that everything worked properly. To then unlock my bootloader i used the flashing script and i was set. This is recoverable not easy but you can recover.
Thanks Moneyman1978 for your reply. Can you be more detail what you did to resolve this issue. Can you send me the links or point me to Fastool and 141 .SBF file also SMG files. Thanks again.

Well, I had a similar issue. I did the 4.5.141 (OS 2.3.6) OTA update and then it would just bootloop. I'm on stock, rooted, locked BL. I then ran the OTA update again via recovery and that didn't help. I then did a full factory reset, then update via recovery and still didn't fix anything (good thing I had TiBu backup). After calling AT&T they finally admitted that Moto recalled the 4.5.141 build update since there was WIDESPREAD boot-loop issues with many Atrix users. Great.
They're sending me a new phone. Luckily, mine is in good condition.
Any one please have any suggestions for me. Do you think it is a hardware issue or can it be fixed by fixing the software??? Any help is appreciated.
If any of you has any ideas about how to fix this issue I would appreciate if you can share it here.

Nexus 4 TWRP encryption with password - I think the phone is gone

So, I have read a lot about TWRP sometimes bugging out and randomly encrypting phones and adding a password to which the user either never set it up or that TWRP doesn't accept it. This has recently happened to me and I cannot use my phone and I don't know what to do.
I have had the bootloader of my phone unlocked since day 1 when I bought my phone (release date last year) and have been running PA ever since. I have never had any problems with it, until about 5 days ago, when I grabbed my phone and everything started crashing and the camera was apparently not available. I didn't know what was the deal with it, so I rebooted the phone and it entered a bootloop (it hangs on the Google logo for about 5 minutes and then it hangs on the PA logo screen forever). I went on to the bootloader and started TWRP to see what was the deal. I originally wanted to grab certain files off the phone in case I had to do a system format, but when I got to TWRP, it asked me for a password which I have never set up and I tried every combination I could think of but it always failed. Everything was encrypted and without the password I couldn't get to it. I tried wiping everything including a factory reset before resorting to a system format (which I read about it and apparently is meant to be the solution). Everything failed because it couldn't access the /cache, /data, nothing. I went on to do a system format and although that is meant to wipe the phone and remove encryptions, it also failed to wipe the /cache and although TWRP says that the wipe is successful, the phone is still encrypted, the password is still around and it bootloops. I have tried the system format like 50 times and always the same.
Can anyone help me out with this? I am currently travelling around but am at a hostel where there is great internet and pcs, so I can install drivers, toolkits and such. I actually started looking around for new phones, since I cannot for the life of me get the phone to start again.
Note: The phone was working perfectly fine, I put it down to have dinner and once I finished, I tried to use it and it started to bug out. I also read around about this, and everyone's issue gets fixed after a system format.
Any help, would be greatly appreciated, that phone is the only net device I have on this trip and it sucks to not have any way to contact anyone.
Thanks.

Don't blame TWRP for something it doesn't do.
Looks like your device have an EMMC failure, sorry.
You can try installing factory image, or last resort restoring by download mode, but I think the flash memory in your phone is gone.

I didn't mean to blame TWRP. It is just that it was when I am on it that I get asked for the password and I was under the impression that it was TWRP that did the encrypting (I am in no way a developer or even very knowledgeable when it comes to the under the hood stuff, I usually only follow the tutorials). But thanks for the reply and the link, I will try that and hopefully get the phone back working.
Also, I did read in a thread that apparently this can occur due to hardware failure, I was just hoping this wasn't the case.
This happened to me on an old phone. Not sure why. Factory image fixed it. Could be a different issue but its worth a shot.

Did it suddenly happen or did you change ROMs?
I tried a new rom for the first time and then went back to wicked 9.1, I'm thinking that triggered something.

Massive softbrick (haven't found a solution yet)

Hello everyone,
So here's my story: I got a 6P short after release and it's been amazing. After switching from a S6 I couldn't be happier until 3 days ago.
I was playing around with my phone (checking for updates on the play store if I recall correctly) and I was going to switch from 4g to wifi. I went ahead and pulled down my notification shade and went to press WiFi but misclicked and hit Hotspot which was below it. My phone suddenly froze big time and this is for the first time ever since purchase.
At first I thought I'd wait it out since the device was completely unresponsive, home button didn't work and neither did anything on screen. Buttons didn't make a difference either. 10 minutes went by and I ended up force restarting by holding down power + volume up. First part of my bootup went fine but when it got to the android boot animation after I put in my pin to allow the device to start it dropped from the smooth usual framerate down to 1 frame every 10-15 seconds and it slowed down further until it came to a complete halt around the time the android letters appear.
My first thought was corrupt rom so I went ahead and wiped data from the stock recovery. I was running completely stock with no modifications whatsoever. That didn't do anything. Phone still froze in the same boot phase. Desperate I unlocked bootloader to flash a clean fresh image to try to fix it and to my surprise that didn't change a thing.
As I was getting pretty desperate already I had one more idea and that was to flash up to the Dev preview. To my huge surprise it booted and I jumped from excitement. So I started setting up my phone again. I got past the prompt to insert sim card and I was now at the screen to choose a wifi network. As soon as I clicked into that the phone froze up again and at that point I lost all hope.
I wiped data in stock recovery and shut the phone down for the night. On day 3, today I woke up and tried starting the phone and it worked as if nothing had happened. I went through the setup and set up my phone on the N preview. At a certain point I was planning to go back to the latest official build but for now I was happy my phone was back from the dead. Later today I tried to restart my phone to clear all running apps etc and it froze up on boot.
I'm losing all hope that I'll be resolving this myself so I'm reaching out to the community to see if anyone's had this happen to them before and hopefuly for a solution. It's still under warranty so I can eventually send it back to the retailer but I'd rather not have a phone for 3 weeks.
Any and all help is appreciated.
Thank you for reading through my long and probably pretty boring story!
Have you tried flashing the factory image? If yes, did you made sure to wipe/erase the system, boot, vendor, and cache partition before flash the corresponding img files?
To the OP, is there any reason you did not flash to release version 6 instead of Dev preview ?
Also, any reason you can not simply do the "unenroll" from https://www.google.com/android/beta ?
It will require you to setup certain settings again as you will be back to a "factory reset".

DJBhardwaj, i haven't specifically erased those partitions. I was under the impression wipe userdata along with reflashing did that. I will try that tonight when I get home!
Xdafly, I only updated up to N as a last resort because at first I had a locked BL. I was planning to unenrol but that would've been too late as it self bricked after a restart.

Well I just did the erase thingy and my phone booted but wifi won't turn on. Enabling hotspot doesn't brick anymore but I now suspect WiFi might've been the issue. Any tips on how to find out what it could be and possibly fix it?
Edit: 2 restarts and a factory reset later I'm back to bricked same way as before.
try safe mode

That was my first thought, that was the restart that bricked it again. Safe mode shouldn't have made a difference since I hadn't even logged into Google account for apps.
After reading the very first post; sounds like bad WiFi hardware.
All the hanging has been related to WiFi or Hotspot.
I think you should get a replacement

Is your phone rooted and did you install Xposed?
Over the weekend I shutdown my 6p (stock rooted with April security patch, Xposed v80) and charged it. When it turned it back up I kept getting "Unfortunately, nfc service has stopped". Long story short: I ended up factory reset my phone and reinstalled EVERYTHING and I still got into bootloop. Then I came across
https://github.com/rovo89/Xposed/issues/113
https://github.com/rovo89/android_art/issues/28
At the end of the second post rovo89 (developer of Xposed) fixed the bug in V83. I wiped my 6p once more and installed everything with v83. Problem solved.
Good luck!

Anybody else have a main board failure? Here is my story.

Last week I was minding my own business, doing usual stuff on my phone and the device spontaneously rebooted into a bootloop at the Google logo. So I think "OK, no problem... I can try wiping cache/dalvik or at worst I have a recent nandroid backup" and proceed to reboot into recovery... except that it still hangs on the Google logo. Stuck at work I did a bunch of googling and found one other user who had the same thing happen recently.
When I got home I tried to fastboot flash TWRP again... but alas was still stuck at the Google logo. Next was a full flash of Google stock images, but that did nothing either... so I relocked the bootloader and had my provider (TELUS) send it in for warranty repair. I just had it returned with the repair stating the main board was replaced.
I have noticed a few users posting about being stuck on the Google logo and this concerns me a bit, as it almost seems like there may be some inherent hardware flaw causing the issue.
So I'm throwing the questions out there: Has anyone else had similar problems and is this something we should start to be concerned with?
You're not alone buddy. I'm in the same boat. Have sent mine for repair yesterday.
Thats discouraging news. How long have you guys owned the phone? Did you buy it new?
I love my 6p but if enough of these units are defective they should probably be recalled. Hard to gauge if its an anomaly or a serious issue. Hope for the former...
I think I may have the same problem. My phone wont boot past the logo at all. IDK what to do at all.
I have the same problem, stuck on the google logo, I already wiped the cache partition and nothing, did a factory reset and nothing, what else can I do??

Check if you can boot twrp. If you're not successful send the phone for repair. No option available to recover from this king of hard brick yet.
Weird thing is anything and everything is doable in fastboot. Moment you try to boot OS or recovery, gets stuck indefinitely in Google logo and reboot.

this exact thing literally just happened to me on Thursday. I was fully stock never unlocked the bootloader or anything. phone suddenly started looping, tried wiping cache, doing factory reset, finally went nuclear and unlocked the bootloader and flashed system images. nothing worked. warranty replacement is enroute.
I bought it on release day.

I got the phone new from TELUS at the end of December, so about 6mo before I had the issue... Thankfully fastboot still worked so I could return to stock and relock the bootloader before warranty claim...
Starting to wish I had done the insurance option if these things are failing after 6mo and I'm on a 2yr contract

I'm also having this issue, but I get stuck at the boot animation instead.
I have Nexus 6P, Stock Android 6.0.1 July, SuperSu v2.74, franco kernel r23, Xposed v85. Everything was running fine when suddenly the phone rebooted and got stuck in boot. I reboot into recovery, deleted the /data/data/de.robv.android.xposed.installer/conf/modules.xml, flashed xposed unistaller zip, cleared cache and rebooted. Still stuck in boot. I reboot into bootloader, flash boot, system, vendor image of July factory image and reboot. Still get stuck at boot. This is happening for the third time to me. Happened in May, in June and now in July. Only thing that works is restoring a nandroid and then again flashing the latest factory image. But that way, I lose days / weeks of data, depending on when that last nandroid was created.
That really sucks, but doesn't sound like a hardware failure from my understanding... I lost ALL my data when I had to send it in, since my failure resulted in no access to the internal memory... Lost a few pictures which was a real bummer, but lesson learned and now I'll be backing up my memory more frequently and also setting up cloud backup for photos

It's likely a software failure. When you flash via fastboot, do you reboot back to bootloader after flashing radio and bootloader? If not then that's likely what's causing the fast boot method to fail for you. The first time after I did a complete fastboot flash of the software I fell asleep and woke up in the morning to my 6p still at the boot screen. When I re-traced my steps I found out that my mistake was not properly rebooting after flashing radio image, then doing another reboot after flashing bootloader.
Got my device back. Same exterior. Was told that motherboard was changed. I could notice that from fastboot.
eMMC changed from Samsung to Toshiba
DRAM changed from Hynix to Samsung.
My device joins this list. Gonna send it for repair tomorrow and hoping it is covered under warranty.
Additional update. I know I missed the bigger scheme that changed. My IMEI.
Just curious what happens if I restore my previous efs partition backup after backing up current.

my phone randomly locked up, then rebooted today. But when it rebooted it was stuck with the white google logo flashing. I can get into the bootloader mode, but from there, choosing recovery or anything else gets back into the white google bootloop. I called service and they're sending me a replacement. Phone was stock with a locked bootloader.

XT907 bricked (probably partitions in read-only)

Good morning.
After almost 3 years with no problems with a XT907, I have again an issue with it (this time, my father's one). Again, I come to you requesting help.
It all started with all apps crashing over and over. With an old XT907 I have for emergencies, the common fix method is flashing VZW_XT907_4.4.2-KDA20.62-15.1_1FF.xml.zip with RSD Lite v6.1.5 and all solved.
I tried that method with my father unit, and when it started again, all process were still crashing. I thought it was still nothing (just a harder issue), and tried flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip, just deleting all his data, to fix it.
When the process ended, it turned on and it had still the same problem. In this point, I got worried the /system and /data partitions got locked
I re-started, went to stock Recovery, and wiped system and cache. Then, went to Fastboot a third time and tried again flashing VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF_SVC.xml.zip. Guess what? Still the same problem
The phone turns on, but ALL apps keep crashing over and over. I can't even take an screenshot, as it immediately reboots.
Someone know what happened with it? And... how to fix this issue?
