[Q] Need to unlock bootloader, but borked device

Basically, I tried to flash the latest 5.1 image but unsuccessfully as the system.img wasn't extracted. For some reason I locked the bootloader and now I can't boot into a working system, and I can't reflash anything as the bootloader is locked. When attempting to unlock, it is telling me to go into dev settings to allow unlock.
Is there anything I can do?

Few threads about this today. Seems a regular user error. Can't think of a fix right now..

Hmm, thanks anyway. I think this means I'm bricked. Moto E time I think.

Can't be done.

Have the same problem and try to solve it with Motorola. No luck at the moment.

Can't. Boot loader is locked and requires a setting in android to be changed but android can't boot. Catch 22

Are you positive? I just flashed a Nexus 7 from 5.0.2 to 4.4.4 with fastboot. fastboot oem unlock worked without checking that box.

Damn, that's really lame...

Wow this craps really ticking me off with this update and all. I have been rooting modding for years and every damn time I get a device that uses fastboot I get nothing but trouble. I hard bricked three devices in the past with fastboot and it seems over the years fastboot hasn't gotten any better or easier. What a shame I love the nexus 6 but I'm seriously starting to reconsider and going back to the good old Odin devices.

I'm an idiot.
I made the mistake of trying to update my Nexus 6 (Stock 5.0 encrypted, rooted, Xposed) while talking to AT&T customer service on my other phone. Distracted flashing is a bad idea. I am sure I made SEVERAL mistakes.
I too was trying to flash the new 5.1 image and got an error when running ./flash-all.sh (I'm on a Macbook). Friend suggested I try to do it by flashing the boot.img recovery.img and then system.img manually. Got the boot to flash. Recovery flashed. System failed. Unfortunately I have closed the terminal windows and don't have the errors anymore. When it failed it said something about insufficient space. So (I'm assuming this is where I f**ked up) I hit start from the boot loader screen to boot into the system and delete some things even though I had plenty of space (over 20gb). It booted fine. When I went to reboot into bootloader, I accidentally selected recovery. It booted back into TWRP which confused me. I thought best bet would be to wipe the device and start over fresh. I wiped everything and booted back into bootloader... blackness. Now I have no response from the device at all. Nothing. No response from the power button. Nothing when I plug to a charger. Just blackness. Just a pretty, 2 day old Nexus 6 (warranty replacement from T-Mobile on Tuesday).

You wiped the boot partition too? Ouch...
Last time I did that, it was with my Nook Color. Thankfully that was able to boot from SD cards...
I have a similar problem with another Nexus 7 right now. Flash went corrupt, won't boot at all. No bootloader, no Google logo, nothing.
My only hope is that the device still talks to the computer, it shows up as a Qualcomm device under Ports in Windows Dev Manager. QPST picks it up and says it's in download mode. If I can source the hex files to flash, I think I can bring it back. I'm only sharing that because it might be your only hope too. Godspeed, sir.

lol, whats so hard with fastboot? fastboot oem unlock is rocket science? how about fastboot flash recovery recname.img? only way to hardbrick with fastboot is to flaah something to your device that doesnt belong there, or flash something into the wrong partition. how did you "hard brick" with fastboot???

The problem is that bootloader got relocked, and the OP is unable to get to the setting to enable oem unlock. Fastboot is errors out saying to Check "Allow OEM unlock", and FAILED (remote failure).

I would find it hard to believe that there is no solution to this. With all the bright minds here on XDA, I'm sure it can be figured out. The unlock setting must be stored somewhere, and it should be accessible.
When I first got my Nexus 6, I booted into the bootloader right after taking it out of the box (i.e., without booting into Android), and I was able to unlock the bootloader without having checked "Allow OEM unlock" in developer options. This could mean that the setting could potentially be located in /data somewhere.
OP, have you tried a factory reset in recovery? Have you tried playing around with the other bootloader menu items (e.g., "Factory", etc.)?

Thank you for taking a look at my post. I have tried all the options in the bootloader menu with no dice. Things aren't looking promising for me...

You're all using the newest fastboot?

ADB Works, Fastboot still "waiting for any device"

I have been blundering my way though the internet to get my ROG Phone 2 rooted. I have unlocked the bootloader, I have a modified boot image from magisk, I have the ADB connection set up through USB and it works fantastically. I honestly don't know how I got it work, it involved many different driver update attempts and then figuring out I hadn't put the phone into USB debugging, but now fastboot doesn't work.
ADB will list the device, but fastboot cannot see it. I have tried rebooting the phone into the bootloader, but there is no connection on either. Not sure why I thought that would work, but I tried. I really don't understand enough about fastboot to get any farther on my own.
I have the tencent version and I was pretty certain I have the CN android 9.0 on it, but I am no longer certain of that. I am running windows 10.
This is my build number: PKQ1.190414.001.WW_Phone-16.0622.1906.19-0
I honestly don't know, but does that WW mean my tencent phone is running the WW firmware?

Fun fact, I just got Fastboot access from my computer by using the side USB port and rebooting into the bootloader from ADB. Still not to sure about the version bit. I think I'm just going to give it whirl and brick my device, maybe.

1. You are running a WW rom, but that doesn't necessarily mean your fingerprint is matched. To update you need to have both WW rom and WW fingerprint. You can check if your fingerprint is CN or WW using device info hw from playstore under 'system'
2. In order to root you need to have a matching root boot img for your current rom ie root img for 1906.19, just checking that your know this?
3. Have you managed to get the phone recognised using the cmd 'fastboot devices'? Also are you using the side port?
4.when you say bootloader, have you definitely got the phone in fastboot mode - hold vol up and power button until you see the screen with some options. That screen is fastboot mode, you don't need to select any further options. Once in that mode, connect to pc, open adb and run the fastboot devices cmd. Once your device is recognised, report back here for further steps

Thanks for the reply! I did indeed get fastboot to work over USB. Fastboot devices reported back the serial number and everything. I did not know that the build need to match on both the boot and the rom, but that does make sense and I probably should have realized that before I went ahead and copied the rooted boot.img I had over. Then my phone couldn't boot up proper, and got stuck in fastboot. Then I went ahead and copied all of the contents of the same rom over and now it is literally just a black screen. Won't turn on any more. I think I super bricked it.
Sorry I didn't see your post earlier and I know I am not father into the deep end, but is there a way out from where I am.

Nope. The only response I can get out of it now is when I plug it into the fastboot port, the computer recognizes that something was plugged in. I don't even get a device on a device manager.

Try holding the power button for around 20 secs until it shuts down. Then try vol up and power together and see if you get back to fastboot. If that doesn't work try vol up vol down and power buttons all together. Then try again to put it in fastboot mode using vol up and power. Let us know what happens /if you can reach fastboot mode

Unfortunately, nothing. Holding power for 20 seconds showed nothing, and like wise for volume up and power. Battery was fully charged too. Had it plugged in for most of today while I was trying to get fastboot to work.

Is there any sort of illumination to the black screen ie do you think the phone is on but the screen is black or do think the phone is completely off?
Holding power button for a while should switch it off after a while. Try holding for longer than 20 secs, then try booting into fastboot mode

Try a USB 2.0 port? Surprisingly this works for some phones even though it's compatible with 3.0.

Well, It's been untouched for a day now, and it still will not react to input. No response from long hold on the power button. I will try again in the morning. Is it possible that I somehow wrote into the BIOS of the phone? Android does use a BIOS, right?

Android itself does not have a BIOS, since Android is an OS and BIOS is more similar to firmware. But yes, the phone does have firmware, and it could be that the mismatch in firmware versions (from which you tried to flash), has caused the bootloader to "not know what to do now" when trying to start the phone up.
One thing which comes with all phones with a Qualcomm chipset is something called Qualcomm Crashdump Mode. You can try to see if you can get your phone in EDL (emergency download) mode and restore the correct firmware in that way:
https://www.the***********.com/rog-phone-2-unbrick-guide (URL gets censored for some reason; it should be "the custom droid" with no spaces)
Also, if you continue to have driver issues with connecting the phone to your PC, are you able to test another PC or even a Mac if you have access to one? I find Windows can be a giant pain for getting ADB and fastboot to work properly at times.
Good luck and let us know how it goes.

Ok, so here's where I am: I have left the phone unplugged for a long time now. Really had no effect. I just downloaded QPST and I can actually get my computer to see the phone. However, I am still not quite sure how to USE QPST and not make things worse. So this is my plan: I am going to look through the forums here for info on how to use QPST to get my phone working again. Not really sure what that will look like, but fastboot would be a good start. From there, it sounds like I have to get the original firmware back on it, and then go about the process of rooting once again.
Still leaves me with the issue that started me down the path of rooting this phone, but at least it will not longer be bricked.

You may not HAVE to flash complete firmware, it is quite likely that the boot.img is causing the problem as you flashed an incompatible version. Below you'll flash the correct version which HOPEFULLY will fix your phone, provided you can get into fastboot mode now.
Haven't read back through all the thread so i can't recall all the details of where you're at. As far as i can tell you're still running WW 16.0622.1906.19-0, correct? Can you get the device to now boot into fastboot mode? (from a powered off state, press and hold vol up and power at the same time. You should then be presented with some options, DON'T select any option. With that menu screen open is fastboot mode.
1. Download and install ADB Fastboot from here to C: drive of your pc/laptop.
2. With your phone in fastboot mode (as detailed above) connect it to pc/laptop using the side port of the phone.
3. Navigate to C:\Program Files (x86)\Minimal ADB and Fastboot folder and double click the cmd-here.exe, this will open a cmd window.
4. Type 'fastboot devices' to check that it's recognised, there should be a serial/key shown after entering that cmd.
5. Provided the serial/key is shown in fastboot mode, download the following boot.img (which is for WW 1906.19) from here.
6. Copy that boot img to the same folder you have open for ADB (C:\Program Files (x86)\Minimal ADB and Fastboot)
7. In the cmd window type 'fastboot flash boot boot.img'.
Now, that boot img is the STOCK boot img for your rom version. Don't worry about rooting for now (if i recall correctly, your phone won't boot to system), let's just try to get the phone booting first. Providing there are no errors when flashing the boot img, on the phone fastboot menu, scroll through and choose 'restart'.
Let me know if the device boots to system now... Good luck
I'll pm you my email address so you'll be able to get hold of me if you get stuck at any stage...
EDIT: was forgetting you tried so many times to get into fastboot mode, without success.

Dude, is your phone screen still black but switched on? When you tap the screen does it vibrate. I'm thinking you might already be in edl mode (which could be a good thing). Let us know
Check your pm's dude for further info. I can't post links to the site required so have sent via pm

Just dropping you a quick note to say thanks for thanks! LOL. Yeah, your post earlier seems like the best place to go. Have used Miflash Tool a few times on Xiaomi devices, it's pretty good and straight forward. Should be a LOT easier than using QPST and having to change EMMC to UFS.
Can't remember where i saw it now, but i'm sure i read that if the phone screen is black (but switched on) and vibrates, then it's likely to be in EDL mode already. Which will hopefully be good news for @RichDoe252. Before that (having never been in that situation), i wasn't aware that an all black screen could mean EDL mode is active. Fingers crossed for Rich it'll all work out just fine.
@RichDoe252 If all goes successfully using the QPST file download (and using the Miflash Tool the guide mentions in the pm i sent you) and flashing, DON'T ROOT JUST YET!!!! LOL. Let us know how it goes and then we can look into, and point you in the right direction, for getting you rooted and up to date on latest A9 or A10 whichever you'd prefer

Well I must say Rich, I'm surprised you haven't been back here yet to give any updates on progress!! Sent you a couple of emails through pm... Man, if it was my fairly expensive phone that was in the poo pan, I'd be all over trying to fix it lol

First off, you are a freaking saint. I really do appreciate all the help you have been offering up, and I am sorry I have not been very quick with a response. As my phone currently stands, I get 0% response from anything I do to it. No vibrate, nothing. No indication it even is plugged in. I had it connected to my PC with QPST installed, and it was able to pick up that the phone was there, and then immediately tried to download something to it. Not sure what, not sure why, but that kinda typifiies my interaction with this whole process so far. If you haven't guessed, I'm kinda in over my head.
Back to the problem: QPST started some opperation to download something to it. Wouldn't let me do anything else, said the phone was in "download mode". Either way it stopped at 30% and didn't progress for 30 minutes, so I tried to unplug it and plug it back in. Same interaction. Unable to do anything to the phone, no reaction from the phone what so ever. This was, by the way, plugged into the fastboot side port.
I saw that you PM'ed me, and now I can't find the email notification or the PMs on the site. Forgive me for being unfortunately new at this. I will get back to you bud, and thank you again.

Pixel 5 Stuck on boot loop

Hi All,
I'm hoping someone will be able to help as I've spent most of the day chasing my tail it seems.
My 'stock' (non-rooted/non-flashed) Pixel 5 went into a boot loop randomly last night.
I've restarted, I've gone into the recovery mode and have tried to flash an OTA via ADB (which may not sound like much but is an achievement for someone with my limited technical skills), it's getting to 94% and then I'm receiving an error on the cmd prompt saying 'adb: failed to read command: No error' but on the phone itself it says that is was a 'success' status 0.
I've tried the current OTA and the developer version and I'm getting the above issue on both.
I tried copying the 'zip' to a USB stick and have plugged that in using the USB A to USB C dongle that comes with the pixel but I'm receiving an error stating that it cannot be initiated.
Can anyone suggest a possible next step? I have some files that I've realised don't go to my cloud backup and they are important to me so I'd like to if possible not have to wipe the device.
Many thanks.

Are you using the latest ADB from the android SDK?
You can always try the factory image and remove the -w from the flash-all.cmd file.

Hi, thanks for taking the time to respond. Everything was downloaded yesterday so is up to date. I re-downloaded just now and checked again and am still getting the same.
(~94%) adb: failed to read command: No error on cmd
Install from ADB completed with status 0 on the phone.
Is there a simple guide on how to flash-all (for someone as not technical as me) that you can point me towards?

Have you try to flash your new firmware on the web? Go to web https://developers.google.com/android/images. Click on Flash and follow instructions.

did you try a different cable or usb port? borrow your friend's pc perhaps?

Hi, thanks for this, I'll try another sideload with the April update and attempt it from another laptop, if that still doesn't work then I'll try the flash as you suggest.

Hi, no not yet. I think this will be the last step before I factory reset. Will try another cable, laptop and the April OTA this evening when I have time.

Also a note on trying to use the web flash utility. Make sure to look at the advanced options on the installation page, it gives you an option to flash the latest update without wiping your device at all.
That could help in getting the phone running again so you can recover your important files, before deciding to do a compete wipe, if that's what you have planned.
Just look around the settings carefully before flashing and everything should go well .

The same thing happened to me, it must have been the April update, I updated my phone, everything seemed to work and then all of the sudden I was watching a video last night and the phone rebooted itself and kept being stuck in boot, it won't load the os but it keeps restarting itself.
I tried accesing recovery mode but on the bootloader screen it won't let me use the volume keys to start the phone in recovery mode or to try and hard reset it, while on the bootloader screen it resets itself... :/ I'll give google a call

The same thing happened to me, it must have been the April update, I updated my phone, everything seemed to work and then all of the sudden I was watching a video last night and the phone rebooted itself and kept being stuck in boot, it won't load the os but it keeps restarting itself.

That sucks. Hopefully they'll be able to do something more than just a factory reset.
I've tried sideloading the April update and that also failed at 94%. Will try another laptop in a while and see if that works, then try the flash as suggested above, if not then it's a factory reset for me.

Also a note on trying to use the web flash utility. Make sure to look at the advanced options on the installation page, it gives you an option to flash the latest update without wiping your device at all.
That could help in getting the phone running again so you can recover your important files, before deciding to do a compete wipe, if that's what you have planned.
Just look around the settings carefully before flashing and everything should go well .

Thanks, will have a look around and see what I can work out. It's looking like I'll have to go this route...

You do not need to bootloader unlock to use official firmware. You've been trying to do an OTA update, you can try the factory images above. Use the "link" to get a download, unzip, edit the flash-all.bat file, remove the -w from the fastboot flash update line.
Code:
fastboot -w update image-redfin-rq2a.210405.005.zip
Code:
fastboot update image-redfin-rq2a.210405.005.zip

Thanks, I tried that. Edited the file and tried running the flash-all.bat file but it's giving me an error:
Setting current slot to 'b' FAILED (remote: 'Fastboot command (set_active: ) is not allowed when locked')
fastboot: error: Command failed
Not sure what I'm doing wrong. Am I missing a step? Should the phone be on a certain menu when running the bat file?

Is that a fact? I haven't had a bl unlock for many years now but I thought I could only do an OTA flash from fastboot with a locked bootloader. I know I can factory reset but other than that .. So if I loaded the beta 12 I could go back and flash a factory image? I would certainly flip the OEM switch first just in case.

That's a good question. I assumed it was possible otherwise why have a factory image available. The consensus seems to be mixed though.
OP: I just did an update from January to April and yes I also got the error at 94% from ADB but the phone reported status 0. Booted up no problem. Have you tried booting into safe mode? Is USB Debugging on? Can you get a logcat of the attempted boot?

Hi,
I've tried booting into safe mode by keeping the volume down button pressed but no luck.
I'm pretty sure that the USB debugging is enabled, but not 100% certain.
How would I go about getting logcat of the attempted boot?
Thanks for all the help thus far.

You'll have to factory reset in recovery. I had something similar happen yesterday morning. The reboot was done by me on the way to work though. A factory reset fixed it. Of course all user data was wiped, but Google backups did a good job of restoring almost everything I wanted restored (except for apps not on the G Play Store of course). You'll need to sign into everything again, but most things won't be lost including root.

Question Black screen and hard brick

Hello everyone today i flash an incompatible rom with twrp and my screen turn completely black After reboot twrp in recovery .
Do you have solution ?
Sorry for my bad English

Hi if you can open bootloader, flash stock rom

The easy solution is press power+volume down. Phone should boot into fastboot mode. Then flash fastboot ROM without relocking the bootloader.
The other way is taking phone to service center. They'll flash stock in edl mode.

I can't seem to put it in fastboot mode. but by pressing the 3 buttons or by changing the buttons I managed to put it in something else I think that at times I manage to put it on a fastboot but the screen always remains black impossible to know i have this message in device manager (Unknown usb devices request for descriptor) do you think it causes me to reinstall drivers what could be the cause? how to adjust as soon as i can connect it so l is not a Qualcomm USB hs 2008.

Doesn't EDL need authorized mi account these days? It'd better to visit service center because installing EDL driver & all the fuss will be useless

May be you can find some drivers which can recognise your phone to work with ADB in fastboot and flash a new ROM. If that doesn't work, then a service center is the next best option.

Sounds like your device boots into EDL mode, likely due to a corrupted bootloader from the incompatible firmware you've flashed. If you have the EDL firehose files for your device, you can use QFIL to flash a compatible ROM, alternatively try to EDL flash the boot partition with a working boot (that may get you from EDL to a soft brick with a working bootloader and Fastboot - from there you can try try and flash a working firmware).

I unfortunately tried to install all the drivers but nothing has worked difficult to know if a fastboot is started it's a hassle when the screen is completely black even with the task manager open I don't I did not succeed finally I ended up paying someone who had me unlock my phone it cost me 29 € my phone is now unlocked which I can advise on the other hand for those who would like to install roms or root their phone is good it is to wait until no auth file is leaked

I see it's super interesting as information I did not know that we could flash only a partition with QFIL.
Unfortunately I could not find the firehose files for the phone as the phone is probably very recent.
I had to pay someone to unlock my phone with an edl account of course .
My work now

Was the unlocking done in person or online? Anyways glad to see it's sorted out.

Question Redmi Note 11 Stuck/boot loop in Recovery mode

I need help, I did some research but I couldn't find a solution to my problem.
I know that others have a problem with rebooting to recovery when unlocking, but my problem is different. My phone is just stuck in a loop into recovery mode and won't boot normally even in safemode.
I haven't tried wiping the data yet because I want to save my files. Do you have a solution for this?
I turned on USB debugging before this bootloop happened.

How exactly did you set up your custom recovery, and when exactly did it stop working? (has the recovery ever worked normally for you?)

I didn't do anything, I just charged my phone while it was turned off. Then I turned on the phone and the same thing happened as with others where when I unlocked it from the lock screen, the phone restarted and that's what happened.
Edit:
I saw this in another thread, we have the same problem.
KMS45 said:
Hello to everyone,
So basically i read all the 10 pages of this thread and I have not found someone that have the same problem as me. I have the “bootloop” but the thing is that my phone is not even turning on. It is just booting and going back to the recovery menu. So I choose the reboot option but still coming back to the menu. I have already turned on the debug usb option because I used to be using it before my phone dies. I have a Xiaomi MI10 Lite 5G. I also tried the MiAssisstant but no succes because device not detected.
If someone have a solution without wiping all my precious data pls ?

If you have your phone to automatically install updates, it might have done exactly that, and it borked. i.e. incomplete installation. There is no recovery partition on the spes so the boot image is potentially whacked. Try reflashing boot and dtmo and vbmeta images in Fastboot from your current ROM. That should get you back to where you were.

Sorry, I'm not really knowledgeable about this. Can you guide me or give me a link on how to do it? I don't have any experience in flashing through fastboot but earlier, I tried using ADB to check if my device is being recognized and I think it was recognized.
And also, I don't know which firmware to download or what is the current version of my phone because I only know the basic details of my device like this is Redmi Note 11 6/128 4G, I think this is the global version, and by the way, I'm from the Philippines.

Enter fastboot, check your phone is unlocked.
fastboot getvar unlocked (response will be unlocked: yes)
If you are global, then get the fastboot version from here: https://xiaomifirmwareupdater.com/miui/spes/stable/V13.0.12.0.SGCMIXM/
This one is mine. Be careful you get the non-4g-in-the-name ROM for your 4g phone if yours is like mine:
Xiaomi Redmi Note 11 - Full phone specifications
www.gsmarena.com
Beware of the other one that has a Mediatek processor and has 4G in the name and is NOT my phone type: https://www.gsmarena.com/xiaomi_redmi_note_11_4g-11241.php
If this one fails to get you booted at the end, drop back a version and try that one. Check your phone box to see what region version phone you bought.
Unpack it to a folder and get the images for boot, dtbo and vbmeta. Put these files into your adb/platorm-tools directory in Windows. (you will need the boot and vbmeta images later if you choose to install Magisk) Since you ran adb already, then you must already have adb installed.
Open command prompt as root, change to that platform-tools directory.
fastboot devices (to ensure Windows sees you)
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash vbmeta vbmeta.img
Reboot system.
If this gets you booted, run Device Info HW app to see what version is actually installed, and look under About Phone as well.
EDIT: I corrected the 3 command lines above.

Sorry for the delayed reply.
It seems that my bootloader is still locked, so I cannot flash it using fastboot. Is that correct?
Is there a way to flash my device without losing my files? I really need to get my files

Then ignore my steps, since they won't work on a locked bootloader. I will defer to others who have clues regarding a locked bootloader and a down system.
You COULD try to unlock it, but that would definitely wipe all your data:
"Unlocking the bootloader will wipe all data"
Get the unlock tool and instructions here, if you so choose anyway:
Apply for permissions to unlock Mi devices
en.miui.com
NOTE: that gives you unlock version 6.5.224.28 but it might/should prompt you after install to install the updated version since mine is 6.5.406.31 from April of 2022. When you run it, it makes you wait a week.
NOTE 2: It does state this warning, however:
"First, confirm that your device can be unlocked
Your device functions normally and not in a bricked, soft-bricked, bootloop state."
