Now. This is where I want feedback.
I have no "Allow OEM unlocking" or "Enable OEM unlocking" (or anything that says OEM Anything) in Developer Options.
I've read every thread in this xda forum for the Zuk (with exception of the 500+ post TWRP thread).
I've seen multiple people state they also do not have the option listed in Developer Options, but no one seems to address it.
I really, really hate ZukUI. Not to mention I can't access Google Play store.
...but that's a different issue.
Can I have a couple people give recommendations on unlocking the bootloader? Please tell me I can do this.

When you're in fastboot try writing 'fastboot -i 0x2b4c oem unlock' then try to see if it worked with 'fastboot -i 0x2b4c oem device-info'

Please check the last post in this thread from modaco http://www.modaco.com/forums/topic/375804-convert-z1-from-zukui-to-cyanogen-os/?page=2. It seems you need to flash back to earlier zui version before unlock bootloader.

You can't unlock zui 1.2+ loader is locked.

Ok, you're right Gonzaman. I saw your post in another thread and did the 9008 port through QFIL.
I've got the Zuk on CM 12.1-YOG4PAS3OH.
No cell service though. I'm on China Unicom with ! next to wifi and cell signal strength. Any ideas?
Thank you for your help.
Nevermind, I didn't have data connection turned on.

Thanks for the help, Planet X. I'm running CM 12.1 now, loaded through 9008 port through QFIL. I would like to unlock the bootloader, get a different one, etc. But for now, I'm just happy to get rid of ZukUI and have my google services back.

GroovyHistory, be careful - if your situation is anything like mine, you may be unwittingly using mobile data when you mean to be using WiFi. Because we are in China and behind the Great Firewall, Lollipop's screwy Captive Portal Detection protocols will sometimes mark your WiFi with the "!", which means that Android thinks the WiFi data connection isn't working because its attempts to ping Google servers fail. If there's a "!" on your WiFi connection icon, but none of your mobile data connection icon, that means Android is routing your data through your mobile data connection, and not your WiFi (despite being connected to WiFi!). This can lead to unintended large amounts of mobile data usage, which if you pay per MB like (on China Mobile), can be a big pain in the butt.
I think I found a solution last night, however.
If you go into the advanced settings of each of your wifi connections, and add a proxy server of free.kakalook.com, with a port of 33333, it'll ping that server in Singapore (which is unblocked) instead of the Google servers (which are frequently blocked), and remove the "!" on the Wifi connection icon. So your connections will be sure to go through Wifi instead of mobile data.
Not sure if you will encounter this problem, but just wanted to give you a heads-up, since it was causing me major headaches earlier.
(if you want a link to a clearer explanation of this process, message me - I can't put the link in the post since I am a new user on XDA and am not allowed to post links yet)

[Q] Permanent problem with Unlocking Bootloader Nexus S

Hi guys,
I searched forums, web with no positive results. So I start a new thread. Here is the situation: one day my Nexus S (Worldwide edition) froze on restarting with the Google Logo on the screen. Every time I try to turn the phone on it stacks at Google logo. When in the fastboot mode the status is Locked. Every time I try fastboot oem unlock I get Phone’s prompt with Yes or Not to unlock bootloader and after choosing Yes, the status doesn’t change to Unlock. Tried on Linux, Mac, Windows (drivers installed successfully), the same result. Tried to force Flash Stock + Unroot in Wugfresh, doesn’t work due to the Locked Bootloader.
typing "adb devices" in cmd (should return the device number) shows:
List of devices attached
......
Empty line above
Any word of advise how to force Unlocking the Bootloader would be greatly appreciated. Please help. Thank you!

It looks like your device is not recognized in Fastboot mode...
Have you turned on USB Debugging while connecting PC and Allow in Device when Prompt some message ..
Go to fastboot mode and write this command... fastboot devices
If it will give you a message like this
List of devices
1235456785164
Then your devices is successfully recognized...:good:

Pretty sure you have a bad USB cable, the error means the fastboot binaries are working on PC but can not connect to device, often this is due to a bad USB cable or port
Try a new cable, one you can verify works transferring data

Thanks, I tried 3 different cables on 3 different operating systems, with the same problem unlocking the fastboot. When I send fastboot oem unlock the device opens a prompt with Yes or No choice, but after choosing Yes, it stays Locked
Something indeed is strange...
So fastboot is for bootloader and adb is for within os and in recovery.
Try booting into recovery and see if adb works, also boot normal into your bootloop and see if adb works there too

Loading into basic recovery and trying to wipe data/factory reset - doesn't work. adb devices returns the following output:
./adb-linux devices
* daemon not running. starting it now *
* daemon started successfully *
List of devices attached
****empty line here****
Somehow, adb doesn't recognize the device, whereas fastboot devices shows it.
Is there a way to flash new bootmode with the currently locked bootloader?
Thank you!

UPDATE (resolved)
Here is an update. Hope this would help others with similar issue, as I've read many threads and folks complaining that they weren't able to unlock fastboot and further root their Nexus S, and who can't boot the phone, which stacked with Google Logo (soft loop). This was the case with my device and finally I got it resolved. I've read some guy tried to hit the phone and after that he was able to boot phone normally. It related to some hardware electrical circle issue. Anyways, I tried to hit my phone by placing it under the direct sun in balcony for some time until the phone got hot and then power it on. And ooops, my phone started booting passed by that Google Logo which was the good sign. Once the phone booted up, I went ahead and activated USB debugging and restarted the phone into the Fastboot mode. while the phone was still hot and in Fastboot mode I run "fastboot oem unlock" and hey, fastboot is Unlocked! Again, this was done while the phone was hot, any previous attempts (read above) weren't successful. From that point, I went ahead and rooted my Nexus S by Nexus Root Toolkit, available on wugfresh.com/nrt, without a slightest problem. Now my phone is fully rooted, bootable and working fine. I thank all who replied to my thread and tried to help and hope this info would help someone with the similar issue.

Try the first method in this page https://forums.oneplus.net/threads/...ck-guide-for-a-hard-bricked-oneplus-2.347607/
Its worked in my mobile, when i lost everything (even fastboot also gone). Its surely work. It will flash Oneplus 2 official recovery. You should ensure that your device is detected in your computer and Its shows as Qualcomm 9008

Thats means your device is not detected, Did you check device manager in your computer? Is is showing your mobile as Qualcomm 9008?? If it is not please follow the steps on the website, I already given. No need wait 1 hr. If your device is detected, then you can see a green line, and it will finish within 5mnts.

Hi Eldos,
In device manager it shows as RELINK HS-USBQDLoader 9008 (COM8)
i followed your instructions but it still does not work. When i run the MSM8994DownloadTool, it does not do anything.
Anything else i can try. I am stuck in this big problem. When my phone switches off, the only way i can boot is by going to FASTBOOT and running command "fastboot continue" only then my phone boots.
Please help.
Thanks,
Pankaj

Problem Solved
Deep problem
I have gone through all the unbrick guides, even with a Oneplus technician but we weren't able to unbrick it. I'm guessing that after the oxygen 3.0.2 update, I wiped out the partition (not sure). The phone was unlocked with some TWRP version before that. I totally forgot to update it the right way. I can get use fastboot to go into the OS, but trying to flash doesn't work since it's locked. Trying to unlock it supposedly works but it remains locked. We tried the Qualcomm drivers, installed the certificates and the device is seen as Qualcomm 9800 yadda, yadda, yadda, but the MSM8994DownloadTool.exe doesn't detect the device, therefore it stays there doing nothing. Yes, we changed the developer options in the settings but nothing seems to work. The LTE doesn't work properly either...it shows an exclamation mark, so I have to switch to 3G. I'm in dire need of help, and if anyone can help me, you'd certainly qualify for a master tech support agent or something cause not even they could help me with this. Thanks in advance if any of you can help! I'm using a Windows 10 on a Mac, using Parallels VM...

Alcatel OneTouch POP C7 (7041d) Bootloader unlock

Hey guys,
Ive been trying to unlock the bootloader on my phone to install TWRP. I have ADB and fastboot installed properly, I have usb debugging enabled on my system and I am my computer's administrator. When I turn off the phone and then open the terminal in platform-tools, I can type in the command to reboot into the bootloader, and my phone will turn off but the screen will stay blank. If I then type in fastboot devices, I can see my phone and that its connected and ready.
However, when I type in fastboot oem unlock I get back 3 dots in the command line, and nothing hapenns. I can wait there as long as I like, nothing will happen. If I unplug my phone, it says
FAILED (status read failed (Too many links))
finished. total time: 4.945s
I'm running an unrooted 7041d on Android 4.2.2. I also have my phones USB drivers installed (or I think I got the right ones)
Does anybody know what to do / how to help?

Unlocking your device is failing because you haven't ever enabled Allow OEM Unlock or USB Debugging from within the OS. The only way you will be able to unlock the phone is to get it to boot into the OS first, and going into Developer Options to toggle these two settings on. You may be able to use the method linked above to briefly get your phone booted into the OS long enough so you can do this. If you are lucky enough to accomplish this, then you can disable the big cores using a custom kernel.

If you are lucky enough to accomplish this, then you can disable the big cores using a custom kernel.

Hello v12xke,
Thank you for your response.
I am totally failed to go into the os. I am getting only Google Logo and its looping. so I am unable to go in to setting and enable OEM unlocking option in developer option.
do you have any other option to install, repair current version with Unlocked OEM devices ?
Thank You so much.

Hello SlimSnoopOS,
Thanks for giving the link. I checked it but in that links it showing the method to enable OEM and I am totally failed to boot into the OS. I got only Google Logo and it loop again and again. I tried fastboot flashing unlock but It showing me Remote: Device is locked.
Is there any way to installed the New OS or downgrade or repair current version with unlocked OEM Devices?
Looking for your response.
Thank you.

You have to try either of those two methods (extreme heat or extreme cold) to see if you can get it to boot even for a couple minutes. Neither method is quick nor do you have time to mess around once the phone finally boots. You can only upgrade with a locked bootloader. So you are stuck unless you are under warranty or can try the fix.

I'm at work so I can't watch your video. I don't recommend opening up a device if you aren't technically sound enough to follow whatever the instructions are. So, try at your own risk and loss of warranty.

Hey man, here is what I did though my device was rooted/unlocked/custom kernal (EX)
- Put the phone on charge
- Switch on, let it bootloop, eventually it booted [takes a day at times]
- Backup if you need to (eg. ADB pull).
- I have EX manager so I enabled power save mode which disables the 4 big cores. As long as the phone doesn't reboot or die no bootloops.

You will need to get into the OS somehow to toggle the dev settings. Otherwise you will not be able to unlock the bootloader. You will not be able to apply the fix (flash custom kernel) with a locked bootloader, and there is no way to unlock it unless your phone can boot. There are a few "tricks" to use with the heatgun/hairdryer that force the phone into limp mode so it will boot into the OS. Others have claimed that once booted, they have enabled "power savings" under settings>>battery and that prevents the phone from going back into the looping. Keep trying, and good luck with the hairdryer!

Same problem... , i tried several flashes ... nothing!
but seems to me it's a fault on the software ... a bug or a glitch, because it came at the end of february! or a malware of some kind!

If it's a software issue best thing to do is completely wipe your phone. Easiest way is to install Twrp and wipe all incuding internal then flashing fresh stock image. I'm sure there is fastboot commands also to erase (or some other way if can't do neither.) This will remove every last thing from your phone so make sure if you are able to back up pics,docs,downloads,music etc. Last thing though don't think it's causes issues make sure your flashing the right version of February stock image Google finally labled them. Or March if it's out.

Hello Friends,
I got the bootloop problem on my nexus 6p from the last few days.
I Google it to solve the problem with various methods but I am unable to solve the problem. I tried command fastboot flashing unlock but I am getting remote: device is locked. I am unable to unlock usb debugging and oem through fastboot command prompt. When I write command fastboot devices then I get the serial number and when I write the command adb devices then I failed to get the device. I am also unable to get recovery mode.
here is some details of my nexus 6p
BL: angler-03.68
baseband: angler-03.81
product/variant: ANGLER-ROW-VN1
Serial Number: XXXXXXXXXXX
CPU: MSM8994 0x20001
eMMC: 64GB Samsung
DRAM: 3072MB SAMSUNG LPDDR4
Console: ttyHSL0,115200,n8
Battery ok
Device is LOCKED.
Qfuse status: ENABLED.
off-mode-charge: ENABLED.
Download Mode: DISABLED.
Connect USB Data Cable
can you guys help me to overcome this problem and install the new android os.
Looking for your response.
Thank You guys.

Hello, you describe a cluster A57 failure, to fix it you need to boot into your phone enough time to enable USB debugging and OEM unlock then flash a modified kernel or a modified ramdisk
See this thread : https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279/
To boot into your device you need to overheat the CPU so the software will shutdown the faulty A57 clusters to cool down the device as soon as it boot up enable USB debugging and OEM unlock before the A57 clusters goes online (because it will shutdown your device) once you succeed enable USB debugging and OEM unlock flash modified files and enjoy your working (but slower) N6P
I had that problem too, but wasn't able to live thinking that my phone was working with CPU issues, so I bought an other Nexus 6P from a guy on the internet, he was selling it because the screen was broken, I got it for real cheap ! I swapped the screen of my BLOD N6P to the one from the guy, it cost me 60$ to completely fix my phone (way less than buying a new phone or buying a new microprocessor)

Hy!
Already done that... Today It comes back from service, they told me they replaced the PCB ... so... it could be a hardware problem or a malware of some kind that ruins the memory... that's what i think about those problem, but i suspect google has something to do whit it!
So... i'll get back to you when I will have IT! :fingers-crossed:
bootloop can't unlock device
I have had exactly the same problem. I tried in vain using heat or cold to get the thing to boot, but independently found the method of leaving it on charge for a few days, occasionally it will get into the O/S.
So while in the O/S I enabled developer options and adb too (the second time) and unlocked the bootloader.
However it still claims to be "device is LOCKED" in recovery mode. This is really weird. I have also factory reset the phone but that hasn't helped.
Luckily I have read the other posts about power saving mode so I'll try that next, it will save having to flash a non-stock OS.
When people ask why unlocking the bootloader is important to me, this specific situation comes to mind. If you had unlocked your device you could have fixed this easily, mind you you would lose 4 cores.

*** I ran into a similar catch-22 issue on my 6P (H1511) the dreaded bootlooping with OEM Unlock turned OFF. ***
*** Couldn't flash the phone because OEM Unlock was off, and couldn't turn OEM Unlock on because it was bootlooping. ***
*** You MUST be able to fix the bootlooping/freezing at least temporarily, in order to turn on OEM Unlock in Developer Options ***
I have tried the "squeezing" method to no avail.
Then tried the heating method, which worked to a point where it has reached the color circles while booting, but then it started looping again.
I figured there's nothing to loose, so I cranked up the heat on the digital heating plate to exactly 140 Celsius for about 10 minutes covered with a paper towel, with only the upper half of the phone's back touching the heating plate (no need to "cook" the lower part with the battery).
It was still looping after the circles appeared, BUT by leaving it to cool off for about an hour, it has finally booted up into the setup page, so I quickly went to Settings > About/Phone/Software Info > clicked the "Build" line 7 times to enable Developer Options, under which I enabled OEM Unlock and ADB Debug.
If it's still bootlooping, you may try to "freezing" method where you would put the phone into the deep freezer for about an hour.
However, heating has worked for me.
Following that, in FastBoot mode I entered the following 3 versions of the flash unlock commands (only one will work out of the 3 which is fine):
fastboot oem unlock
fastboot flashing unlock
fastboot flashing unlock_critical
Downloaded the latest full stock firmware directly from Google.
https://dl.google.com/dl/android/aosp/angler-opm6.171019.030.b1-factory-ab13a98b.zip
Unzip it, and run flash-all.bat
Once the flashing has finished, DO NOT let it boot up, instead hold down the Volume Down as it's about to reboot, which will kick it into bootloader/fastboot mode.
I have tried flashing the Osmosis zip to patch the boot but it didn't work, it was still bootlooping.
So I have flashed a pre-patched 4-Core Boot kernel to fix the bootlooping issue permanently.
For Android 8.1 OPM6.171019.030 flash this 4-Core Boot with the commands below:
https://androidfilehost.com/?fid=13356325061477269711
fastboot flash boot Huawei_H1511_6P_OPM6.171019.030_Boot_4Core.IMG
fastboot reboot-bootloader
At this point flash a 4-Cores patched TWRP, go into TWRP recovery (hold down Volume Down + Power for 10 seconds, Volume Down to "Recovery", Power) and first "format" Data, then "wipe" Cache, Dalvik-Cache, and Data.
Note, all information on your phone will be lost by the above format/wipe operation.
All done, hope this method may help some of you.
And here are some interesting FastBoot commands I've come across....
C:\ADB>fastboot flashing get_unlock_ability
(bootloader) 1
OKAY [ 0.018s]
Finished. Total time: 0.019s
C:\ADB>fastboot getvar all

all:

Instead of "fastboot getvar all", you can also use "fastboot getvar <variable>" (without the quotes and <>)
Any <variable> from the log above, between "(bootloader)" and the second ":"
For example:
fastboot getvar serialno
Enjoy!
My nexus 6P recently went through this bootloop,
Google screen coming up and stuck there, for 5 days, i was going through many possible solutions throughout the web, but they all said it must boot to OS to be able to unlock oem bootloader,
Finally stuck at extreme heat or cold, extreme heat did'nt work for me, but YES extreme cold did actually work, i kept it in the deep freezer for about half an hour, and then waited 2 min, and plugged the charging cable and powered ON the phone, to my astonishment, it did start and i was able to use the phone.
I have rebooted several times since then, it works fine for certain time, and then crashes and restarts all the time, i can still use th phone but its uncertain when it will restart again.
I tried to install new custom rom, but it still says DEVICE IS LOCKED and i cannot do anything else.

Oneplus 6T qualcomm crash dump error, recovery not working

Hi,
I have oneplus 6T which has suddenly started giving qualcomm crash dump error after normal reboot. I have tried msm tool to flash. Tool shows success but when it boots the mobile at end , same crash dump appears again. have also tried multiple version of msm. Also visited service center but they are suggesting motherboard replacement.
Now i want to try manual flashing. Phone is in bootlocked state. also OEM is not unblocked. Is it possible tounlock OEM when my phone is not booting. also is it possible to change boothlocked state to unlock?
I can go to fastboot by pressing vol UP + DOWN and power button but on selecting recovery option it still goes to same crash dump state.
Please suggest what options do i have?is there any way to recover?
Thanks
If your device is a global model 6t then put it in fastboot mode manually then try "fastboot oem unlock* and see what happens.. Unlocking the bootloader won't fix a hardware issue but it won't hurt anything either. ?
Have you ever unlocked your bootloader and then locked it afterwards? If so I wouldn't recommend it again. I've seen a few people screw up their devices that way on here. I've never since Nexus S days when I began modding my phone's locked a bootloader. I always unlock and leave them unlocked.
**I'd either sell it as is online or get motherboard replaced then unlock bootloader and install whatever you'd I like but don't lock the bootloader after you unlock it. That's just my opinion. I've been on XDA a long time and had many devices over the years and I remember reading about people on 5 or 6 phone's I've had in my past screwing up their phones that way..
Edit added: ?
Thanks for responding
yes device is global model of 6T.
I have not unlocked /locked bootloader in past.
"fastboot oem unlock" gives error as "FAILED (remote: Flashing unlock is not allowed)"

Hi,
yes tried couple of older versions too (listed below).
ANDROID+10+OOS+10.3.5+fajita_41_J.47_200717.zip

6T_MsmDownloadTool_v4.0.59_OOS_v9.0.13.rar
Every time on completion of msm flashing in all the above versions, I still get qualcomm crash dump error.
My question is: Is it necessary for bootloader to be in unlocked state for msm tool to work? if no, is there any other command to unlock the bootloader on a bricked phone as "fastboot oem unlock" and "fastboot flashing unlock" fails with the message "not allowed".
thanks again for responding to the post.

As far as I know no. Because in order to unlock your bootloader you must have access to the screen so that after you send the unlock command you can use your volume buttons to confirm and power button to select yes and then it does its thing...

Hi,
The only screen i have access to is "fastboot mode " which has options like start, power off, restart bootloader, recovery mode.
When i choose recovery it goes back to same qualcomm crashdump.

I think the only thing that may work would be a programmer box (ex: Octopus, Mudusa..) and I'm not even sure if it would or not. I was just about to buy two before this stupid Corona bs hit and made me broker than broke. If you had one of these programmer boxes I'm talking about you may be able to fix it but I'm not 100% sure of it and they cost anywhere from $75-300 depending on which one you're looking at. They make many different programmer boxes and they all are compatible with and do slightly different things.. Sorry I couldn't be of any real help man. I hope you can get this fixed.
I'm quite sure the reason you're being denied when trying to send the bootloader unlock command is because your switch in developer options on your device isn't switched to enable bootloader unlock.
yes you are right ... got same error

Have you tried formatting data and then reboot system? I know that sounds kinda dumb but if I were you I would definitely try that. It might boot up to system. To do this you can plug up to your computer and open command window and manually set phone in fastboot mode where you see the "START" screen. Then from PC terminal do: sudo fastboot -w (hit enter) and then once it wipes , push power button on your device which should still be at the screen that reads START. Your device should then reboot. I'd give that a try for sure if I were in same situation.
What did the service center quote you price wise on motherboard replacement?
The process looks doable I think..
https://www.ifixit.com/Guide/OnePlus+6T+Motherboard+Replacement/129570
I'm assuming motherboard is the mainboard. If so OnePlus has the 6t main board costing more than I paid for my mint 8gb 128gb OnePlus 6t.
https://www.oneplus.com/support/repair-pricing/details?code=9
If you end up trying everything and just can't get it fixed ...
If the cost to repair is two hundred plus dollars I would sell it online as is and add some money to it when you can and grab another used device from swappa.com . I paid $200 for my 6t near mint condition on swappa about 5-6 months ago.
Hmm, unlocking the BL is a mute point if you didn't open the developer options and check usb debugging and oem unlocking... So as the phone is borked at moment, I like the idea of reformatting but I wouldn't reboot after the format.. but have MSM ready to go and use the edl tab in twrp to start the msm...flash away..
tried the format with -w,
erase-successful-but-not-automatically-formatting-cant-determine-partition-type........

Well that's not good.. as flashing with msm wouldn't matter whether the bootloader is lock or not ... As it automatically relocks it anyways... Has me stumped..
Are you sure you didn't flash anything that wasn't specifically made for your model device? I mean after you started to fix the crashdump issue?
Want to hear something crazy.. Two days ago when we were first commenting about this crashdump deal, about an hour after we stopped chatting I took a shower, got out and went to grab my OnePlus 6t off the Dash ac charger and yep, you guessed it!!! Crashdump mode!!!! ?????
I swear man! And I wasn't messing with my device when it occurred either. I was not able to get out of it by manually holding power+ volume -&+ until I saw fastboot mode and then selecting start using power button like the three other times I've experienced this. So I went ahead and booted twrp, and did a clean install of OOS and formatted data and that worked. Is this **** contagious?! ? Tripped me out! Haha!!
I'd give the data format command: fastboot -w then run msm tool like the other user said to do. See if that works.
that sounds creepy.. you getting is 'crashdump':laugh:
i guess what is different in my case is i did not unlock oem. And so none of the commands are working. Phone was working fine and one morning fingerprint scanner did not reco. my finger so i thought of rebooting instead of other method to open and i get this error. i know there was no physical mishandling on my part so its difficult to believe that its a hardware failure and needs main board replacement as service center suggests. i have tried only msm tools (stated here in previous msgs) after service center gave a huge bill (230+)for repair.
and other commands as you stated but none of them have worked anyways so not sure if i did something wrong while self repair.
guess will do one more round format plus msm...

i guess what is different in my case is i did not unlock oem. And so none of the commands are working. Phone was working fine and one morning fingerprint scanner did not reco. my finger so i thought of rebooting instead of other method to open and i get this error. i know there was no physical mishandling on my part so its difficult to believe that its a hardware failure and needs main board replacement as service center suggests. i have tried only msm tools (stated here in previous msgs) after service center gave a huge bill (230+)for repair.
and other commands as you stated but none of them have worked anyways so not sure if i did something wrong while self repair.
guess will do one more round format plus msm...

Far as I know fastboot and adb commands should still work but not commands like booting custom recovery...etc .. Also developer options and usb debugging needs to be set to "on" as well in settings. It sure seems like they would have made some alternate way to access these settings but if they did I've never heard of it. Tell you the truth I've never even used fastboot and adb on anything other than a device that is bootloader unlocked except to unlock the bootloader usually a a day or two after I get my device.. I really have no clue what works and doesn't with BL locked.
What mind boggles me is all over our OP6/6t forums you see people talking about this crashdump issue. And although I've been there 5 or 6 times on my 6t I've always been able to get out of it by holding down power + volume +&- until I see the fastboot screen then releasing. And I guess many people cannot do that. I wonder why? Maybe there are two different crashdumps...? Sure seems that way to me. I've always been able to hold my buttons down and get out of it by rebooting from fastboot mode. Many report they cannot do that. ?
(I wasn't even gonna mention crashdump. My luck my phone will go to it and I won't be able to get out of it like I've been able to before.) ?
Edit added:
sudo fastboot oem device-info
Use that command to show whether device is bootloader unlocked or not. See what it says if you type that in?
Maybe see what this shows afterwards as well:
sudo fastboot gatvar all
I believe your developer options and usb debugging was probably not flipped on as well, in settings?
bro fixed aleady? i got fix for you.
i have tried the commnads you have stated earlier.. still giving output here.
fastboot oem device-info
output below
...
(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
(bootloader) enable_dm_verity: true
(bootloader) have_console: false
(bootloader) selinux_type: SELINUX_TYPE_INVALID
(bootloader) boot_mode: NORMAL_MODE
(bootloader) kmemleak_detect: false
(bootloader) force_training: 0
(bootloader) mount_tempfs: 0
(bootloader) op_abl_version: 0x31
(bootloader) cal_rebootcount: 0x31
OKAY [ 0.027s]
finished. total time: 0.028s
so it's locked
fastboot gatvar all gives the list of options that you can use with fastboot
most of the commands dont work and gives below error
FAILED (remote: Erase is not allowed in Lock State)
yes developer options and usb debugging was probably not flipped either
