Hi guys,
I cant for the life of me get my comp to send anything to the phone's bootloader. It just gets stuck on command prompt. Its really frustrating. My drivers are good and everything is in order. Its a new RMA device that I'm trying to root and send the recovery over fastboot but all it does it gets stuck at "sending." Nothing for a long time. I said eff it and tried restoring with a tar file and still nothing!! WTF LARRY?! Would a factory reset and bootloader relock maybe help it? Bootloader is unlocked but just cant seem to get a CWM sent to bootloader or restore it. Please let me know what you guys think. Much preesh.
Try a different USB port on your computer. Preferably one connected directly to your motherboard.

thanks but still nothing.its just stuck on "sending recovery.img." this is ridiculous. when i had the phone connected via mtp i was also having a hard time transferring anything over a MB.
this is what im also getting after unplugging the cable when it's stuck"

OMG. God Damn USB cable was the problem here. i dont know how USB cables have their on/off days...makes no sense to me.wtf..
I cannot unlock my bootloader. I have a Nexus 16 wifi with 4.2.1 and no other hacks or mods applied. Bone stock.
When attempting this through the Nexus root toolkit or Nexus 7 tool kit or through a fastboot command line device says unlocking now but does not reboot afterwards. When manually rebooting device is not unlocked. I will also add that my device is encrypted through the software provided on the device. Also I cannot factory reset the device through the UI or through the bootloader. Again it says it's doing these tasks but upon boot up I am still asked for my storage unlock password and the device is still back the way it was pre wipe attempts.
Other strange behaviors indicating a wipe attempt are random reboots, Andriod OS process consuming > 40% of my battery. Also device installs the same app updates every time I reboot or if the device reboots on it's own.
I would try un encrypting your device and then try to factory reset and then when you go to unlock the boot loader do not do it through the tool kit instead download android SDK and then unzip the download and then go SDK -> platform-tools and then once inside that folder hold the shift button and right click in the blank space in that folder and then click open command window here, also be sure you have correctly installed the nexus drivers from within the tool kit and then put your nexus in fastboot mode and connect it to the computer and then in the command window type a adb OEM unlock and then follow what it says on the nexus

Unfortunately the only way to un-encrypt device is to reset it to factory spec again which it will not do no matter the method tried. The drivers are correctly installed via the toolkit. The tool kit shows that device serial number. I have installed the SDK and have tryed that method via fastboot 'fastboot oem unlock'. I then follow the directions on device and press the power button. Device is stuck at 'Unlocking now.....' However nothing happens. It does not automatically rebooot or wipe device. When I push the power button the device boots normally as if nothing had happened. Also bootloader is still locked. If I can get it unlocked I think I should be able to wipe it.

Sort of sounds as if the $64,000 question is whether or not the "device encryption" is doing it's job, or whether it has a back door.
I can see why people might actually want the behavior you are describing - so long as Google was making it abundantly clear that such behavior was part of the bargain.
I don't know the answer - looking around ATM.

Wondering too if this is an unintended consequence of encrypting the device. So now that it is encrypted if the device is lost or stolen it's no good to anyone as there is no way to reset it back to a functional device. There has got to be a way to around this. I travel quit a bit for work and that is the only reason I chose to encrypt was in the event it was lost or stolen.
I have an RMA number open with Asus in the event that this cannot be figured out. Really though it is not a hardware issue, it's definitely software related.
Hi all,
I think I just toasted my Nexus 7 3G while trying to upgrade the radio/bootloader, but before I toss it in the trash I wanted to see if many someone had any ideas I have yet to try.
Thanks in advanced to anyone who can help me!
The Problem:
Nexus 7 wont boot and is stuck on the Google logo with the unlocked bootloader icon. Cant boot to boot loader using Power + Volume Down. When I do Power + Both Volume Up and Down the screen goes black after showing the Google logo and my PC detects the device but cant find drivers and dont get anything out of fastboot commands. Power + Volume up does nothing.
Because the unlocked bootloader icon I doubt I could get away with sending it back.
What I did:
I was running CM10.1 with Bootloader unlocked
I installed the following 4.3 ROM - http://forum.xda-developers.com/showthread.php?t=2381991
Rebooted <-- Everything was fine but running on older Radio/Bootloader
I started following the following instructions to upgrade radio + bootloader - http://forum.xda-developers.com/showthread.php?t=2175086
I used TWRP to install the Recovery zip

Hi Mazeri,
I having the same issue as I explained in the original thread.
I was flash the bootloader recovery and radio. Recovery and Bootloader flashes seemed to be ok but the radio flash run ok but when the n7 rebooted got stuck in the google logo.
I have tried all kind of key combinations with no success.
Here is the transcript of my flash commands:

How do you detect the device in your pc? What command are you running?
Im on a mac os x. If I do a fastboot reboot recovery, I get a 'waiting for device' message but there is no information for any combination of key presses.
If you are on a PC, have you tried any toolkit? I've read in a couple of thread that Wug's toolkit have worked to unbrick some devices with issues with the bootloader.
All I did was hold power until the screen goes black, then press and hold both volume up and down. The Google logo shows up and then the screen goes black. Windows then detects a device... but is unable to install a driver for it and it shows up as an unknown device.

Also, I tried with the Nexus 7 tool kit and it failed to detect ADB. Fastboot also does not see the device.
Wug Toolkit also does not seem to work as it requires ADB or Fastboot to be working.
If I could get the device driver to kick in that might work... but something we did while flashs is making the device show up without details such as no device name and no mfg info... so Windows just shuts it down and calls it unknown.
I've got the same prolem Wug or Nexus toolkits cannot detect my N7 .... hix
I just flash the radio and my N7 stuck at Google logo....

Maybe we should check what do ourt n7's have in common... It's strange that the flash worked for other n7 but not for ours.
Maybe that radio file is intended for certain devices (?).
Mine is a EU Nexus7 3G bought in early January this year. I guest is in warranty yet but because of the unlock icon in the start screen, the warranty is void
But I think this is not a problem related with the bootloader since the google logo appears and the unlock icon (so the n7 bootloader detects that it is unlock).
The flashing worked with the bootloader but it crashed when the radio was flashed for the three of us, so it is something related with the baseband. The OS installed should not be related since the bootloader and radio baseband are independent from the OS (Maybe you can get a soft brick, stuck in the colored X logo but bootloader should work).
I'm going to try to work finding a solution... but personally Im not feeling very optimistic
Now when I use three button (hold down power & vol + & vol - ) my computer show in device manager : "Android devices/ASUS Transformer APX Interfaces"
Sorry to say, but unless you can get your devices to fastboot mode, I think you're out of luck. It sounds like it doesn't get completely into the bootloader, which is problematic.
It was discussed a while back, and APX mode is a programming mode, but we lack the proper drivers and software to be able to recover anything on the N7 from that. Sorry.
I have a US Nexus 7 3G, got it right when they went on sale.

Bummer news :'( but I was expecting as much. If we don't find a fix, can we replace the main board to fix or is this problem beyond that point? Don't think selling a bricked device is worth it unless we have 0 options.
adb/fastboot commands
Another one bites the dust.
I should have followed the thread more closely. One of the steps (noticed this after the fact) is to "fastboot reboot", unfortunately this does not reboot the bootloader.
I should've noticed this yesterday after the initial fastboot reboot when I flashed the recovery image. Anywho, I believe the last step after flashing the radio should be "fastboot reboot-bootloader" not "fastboot reboot"? Maybe someone with more adb/fastboot experience could verify? Thanks.
bootloop after radio update!!!
my nexus 3g is from poland!!!
please, help!!!
Still no update guys, and no luck also
Right now I am thinking we will need to replace the main board, but I want to get that confirmed before buying a replacement.
I think that radio and bootloader must flashed first before upgrade to 4.3 . I do that with my N7 3G and now it works fine
my radiobands for device is for Poland Region
i hate myself
the only way is to flash radiomodule via APX, i have installed drivers, but have not .cfg and other parameters to flash Nvidia chip.

There isn't a place to know the parameters or whatever we need?
What can we change physically (motherboard, or any specific chip) to solve this problem?
If we return it to Asus or Google can it be repeaired? How much does it cost? Assuming the warranty is void because of the unlock icon..

That was not the reason. I didnt upgrade to 4.3 before flashing the bootloader and the radio and I got the same result. The bootloader is not connected to the OS, but the OS is connected to the bootloader. I mean that it doesnt matter the OS in order the bootloader to run. But maybe it is possible to have the n7 soft bricked if the bootloader installed is not compatible with your OS.
Softbricked is when you are stuck in the OS logo (in case of the stock version is the colored X). This is very easy to fix, just runt in fastboot mode and flash the new OS and that's all. Everyone has experienced this situation eventually.
Our n7 are hard bricked. This mean that the bootloader or the radio (or both) are corrupted or bad flashed. In our case is the radio band (since we can see the google logo that is the bootloader). The weird thing is that while the bootloader is running (we can see the google logo and the unlock icon), we can't enter in the fastboot mode. Since we cant put the n7 in fastboot mode then we cannot flash anything (not os, not radio, not bootloader).
For now, the only way to flash bootloader and radio chip of the n7 is via APX. the problem is the APX configuration to flash the nvidia chips has not been released (as far as I understand, correct me if im wrong), so there is no way to know how to do it.
The only hope is changing this chips physically. Because everything is integrated, that means to change the motherboard, my guess (you can find tutorials in iFixit). What's the downside? The motherboard is basically the N7 so if you change it you change everything (the storage, the 3G, etc). You can check for motherboards in ebay easily just with search: Nexus 7 Motherboards. Range price varies from 20$ for 8GB to 140$ for 3G . Another question is if we can put a 8GB or 16 GB motherboards in our 3G N7, but I think so... it would not be a problem.
Everything I said a personal opinions and I can be wrong, so correct me if I'm wrong.
I have to say, I still have a very very very little hope that could be a fix for this, since we can see the google logo. But I'm thinking in ordering a 8G motherboard just in case
i`m thinking to give my n7 3g to my brother for parts and never buy tablet anymore, only ultrabooks.
My brother had the same problem and he managed to flash 4.2.1 with the nexus 7 toolkit.
The device got back to life again and then took the 4.3 OTA.

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.

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!

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, 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)

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.

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.
Nexus 6P Huawei H1511 Bootlooping fix with OEM Unlock off
sumitpetal said:
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.
Can you guys help me to overcome this problem and install the new android os.
Looking for your response.
Thank You guys.

*** 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]

C:\ADB>fastboot getvar 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.
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
ANDROID+10+OOS+10.3.2+fajita_41_J.44_200222.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 have tried sending "fastboot oem unlock" from pc while i am in fastboot mode. but gives error as
FAILED (remote: Flashing Unlock is not allowed
)
finished. total time: 0.005s
Thanks

None of what I had typed will work because your bootloader is blocked correct?

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
fastboot boot twrp-3.4.0-2-fajita.img

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........
looks like locked bootloader will not let me do anything

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...

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?
