So, I bricked it. All I have is fastboot. It thinks it's locked after I messed with twrp. Partition table is gone, I think, flashing another one is declined due to locked bootloader. The device is unrecognizable in lmsr, thus unable to flash. Deep flash seems to be the only option, but how do I get to there? I'm new with this phone, just 2 days old now. Is possible to open the device up
EDIT: the trick is fastboot oem blankflash

First, let me say this because i've used xda for a while and i know im going to get these responses:
I know this wont reinstate my warranty...
Why? Because I want to. I understand you think it's useless but it's not your phone...
I have tried "fastboot oem lock" and it doesnt work...
I've searched Motorola's site, got on a chat with them which was useless, and searched xda...
So I booted into AP fastboot and connected to my computer. Opened CMD and typed "fastboot oem lock begin"
That seemed to start the process so then ran RSD lite (as admin) and flashed a signed xml of 4.1.2
Yes, I edited the XML first and removed the 2 lines with "getvar" in them
RSD finished and the phone rebooted (which was great because before it was hung up on the unlocked bootloader warning)
Unfortunately after turning the phone off and then back on, the unlocked bootloader warning screen still came up.
And after booting back into AP fastboot it still said UNLOCKED.
did i miss a step?
I need to relock the phone. if anyone has useful information it would be extremely helpful. in the event it just cant be done thats fine. but i feel like it can, because after fastboot oem lock begin the command prompted told me that now i can flashed the signed images.
well crap. i may have just answered my own question. do i have to flash manually through CMD (ie fastboot flash system system.img) AND THEN run fastboot oem lock at the bottom? i'll try it tomorrow.
before i started this the phone was stuck on the bootloader warning screen so if anyone is stuck at that point this will allow you to boot up your phone. and if my results are typical, it did not relock the bootloader (obviously). hope I helped someone. hope someone can help me. thanks.
most likely not feasible
unlocking razr m involves phisically blowing a q-fuse, so you can't go back to locked
even if you could, it would be traced forever that you've unlocked the BL
You can relock the boot loader on the Dev edition, but once unlocked you can never go back to original status 0 of the boot loader and the boot logo will always display the warning even if you relock the boot loader. You have to flash that partition with another logo image to avoid that.
You also need to wipe the user data partition in fastboot first for the fastboot oem lock begin command to complete successfully.
Once that is done, when it reboots you will see that in fastboot it will display status 2 locked instead of status 3 unlocked.
This is a physical change that happens to the hardware when you unlock the boot loader an efuse on the board is blown and that memory location is permanently programmed. Its not even a question of them knowing, even though they do of course, the device itself is altered.

Flash from cwm or twrp.
Trade a locked one for your unlocked one? Lol I'm stuck locked on the newest ota

Before I describe my issue I'll let you know I've been looking up articles on how to solve this for weeks now. first post to XDA, so bear with me I'm new
I have two OPT, both have a similar problem, but one is working (I dare not try to mess with it) and the other I've already tried and tried and now I'm stuck in fastboot, no recovery, no OS.
I HAD an OS on it (Paranoid Android 6.0.1), but I couldn't factory reset, and I needed to, so that I could sell the phone. when I tried to factory reset through OS settings, it would boot loop until I hard reset the phone. I had no recovery apparently (IDK how I did that) but trying to install a recovery requires the "OEM Unlocking" setting to be checked. and for some reason it won't let me check the box. My working OPT phone has the same problem, the "Allow OEM unlocking?" box pops up, I select enable, and the toggle moves itself back to the grayed out selection. so I couldn't install a custom recovery, I can't do any formatting or erasing in fastboot either without that selection for some reason either. trying to only gives me a "FAILED (remote: device is locked. cannot erase images)" or "FAILED (remote: device is locked. cannot flash images)"
AND SO, I tried this (search google for "mega unbrick guide for a hard bricked oneplus 2". I can't post links apparently as it is my first post. it will be on the oneplus website) and now I have no OS. or at least I believe I have no OS because trying boot causes a bootloop. I've tried all the methods, but I'm assuming because my bootloader is locked, It failed with the "A2001_save_brick_mini" tool.
And so, all I have right now is bootloader. didn't have a recovery I guess, and now I think I don't have an OS. and I can't do anything in fastboot because is returns with a "FAILED" hehe. dang locked bootloader. I have no idea how both of these phones have locked bootloaders anyways, because I obviously unlocked the bootloader to install a custom ROM in the first place. did the bootloader relock itself, or maybe during the process of installing the ROM, the bootloader relocked? I'm not sure as I wasn't watching for that. the phones had booted with the new OS, and so I happily went along my business and didn't find out I had a problem until I tried to factory reset one of them.
no I have no phones now with similar problems, but at different stages of the same issue.
My ONE A2005 is working, but I can't toggle the "OEM unlocking". At least it has a working custom recovery (TWRP)
and MY ONE A2003 is stuck in fastboot (fastboot recognizes it via "fastboot devices" and I can reboot and "fastboot oem device-info") with what I believe to be no recovery or OS.
ask me any questions to further explain my predicament, and PLEASE offer me any things to try. I ave two phones to test different things with. I would prefer to keep the working one working though.
Have you tried the fastboot oem unlock command?

Ah yes, I forgot to write that in. That also results in a "FAILED (remote: unlock device to use this command)"
I can't unlock because of the OS, or perhaps lack of OS now; And I can't install a new OS or recovery because my bootloader is locked
use qualcomm recovery tool if you can't get any help. it'll restore your phone to 100% stock
Long story short. I had an Axon 7 A2017 B11 which I updated to B13. I was able to unlock the bootloader, root the phone then flash a custom rom Z.A.D.Mix7_v0.3. I was having fun with the phone but I did something very stupid when I realised I could not use Android pay due to unlocked boot loader. Without doing enough research, I went to fastboot and did a fastboot oem lock. The command was successful but I could no longer boot into the system or recovery or fastboot. I tried MiFlash with B07 which was posted in this forum, but it did not work, came back an error of bad format. Then I used axon7tool to flash TWRP 3.0.2 and the boot.img which I extracted from B13. I am now able to boot into TWRP and fastboot. But I still do not have a working system. I tried fastboot oem unlock, it does not let me do it. I flash ZAD Mix7 again but once I flash that it does not boot anymore. I am now really stuck. What should I do to go back to stock then start everything again. Thanks a lot for the help.
I understand your device doesn't boot into system anymore, but can adb on your pc detect it at all? If so, you can try following all steps after "B)" in my tutorial. I think your aboot img and fbop partition are messed up. If you can use adb to replace the files in aboot and fbop with files that allow the fastboot oem unlock command to be executed, it should be unlockable again. After that, custom ROMs should boot.

I'm having a similar issue. Although my phone boots to stock rom I seem to have messed up my bootloader. I had TWRP and unlocked bootloader. I, similarly, locked the bootloader and things seemed to be fine. After attempting to install Nougat received from OTA I realized my bootloader is corrupted. When I hold the power and volume up the phone seems to just turn off (or go to EDL mode? I'm not sure) I can always just hold power and it'll boot up normally. Is there a way to get the stock bootloader to work and keep it locked?
I also bricked my A7 after relocking my bootloader. I used tenfar's tool to make TWRP my boot.img, then flashed ZTE's stock B20 image. Here's the thread where I found the file links.
From there I updated all the way up to the OTA Nougat, but I suppose you can decide where you want to go after it's unbricked. Hope this helps.
Why are so many people relocking bl? Regardless, always take an ota before locking to ensure you are completely shock.

Don't you have to be running a locked bootloader in order to be able to install OTAs?

No, you do not. I thought that was the case at first as well, but I was mistaken. You do, however, need the stock recovery and an untouched system partition.
My problem is that I don't seem to have a recovery at all. I realized once the ZTE logo pops up I can hold down both volume keys and get to the bootloader. The bootloader is locked but does not display a bootloader version or basedband version. I tried the tenfar tool (axon7root.exe) and now my phone doesn't boot into the system either. I really need help...
Just an update to everyone that helped.
I finally managed to fix it.
I used axon7tool to flash a signed TWRP, so that i can boot into TWRP. The signed TWRP is the only way to make it work. Then I downloaded the A2017 B11 from this thread
https://forum.xda-developers.com/axon-7/development/rom-guide-updates-to-stock-files-via-t3469484
There are two zip files. The boot stack and the rom. Because it is a stock rom, I can boot into the system. The next thing I did was to enable the developer option and turn back on the option to allow OEM unlock.
I went back to TWRP. boot into the fastboot screen. Then I simply typed in 'fastboot oem unlock'.
I went back to TWRP, which says can't read encrypted device. I formated everything. mount the USB then flash the custom rom again.
Hola, phone fixed. Made me sweat for the whole day.
deleted...forgot I had a micro sd card. Flashed stock update from the card and it worked. Phew!
I had hardbricked my devices while installing an OTA update and the device was Hardbricked .
I blank flashed the device and it booted and bootloader.
Now the problem starts here.
I flashed the OEM_Lock.bat as I wanted to relock the bootloader. I'm not sure what went wrong but the flash didn't complete and stuck in middle.
The problem remains here is it shows
Fastboot Reason: Failed to initialize partition table
I am unable to flash anything now. Recovery.img fails, bootloader.img fails, twrp flashing fails.
Nothing flashes as Bootloader is locked.
I went to Motorola Service Centre. They also couldn't do anything and simply said that their software doesnt read the phone.
Is there anyone whoe can really help me out with anything left to do?
Any method to force flash recovery, even twrp?
Phone is detected as Fastboot athene_16mp S in computer. It doesnt detect as "Qualcomm HS-USB QDLoader 9008".
What firmware are you attempting to flash?
Your device looks like it's still on the blank flash provided bootloader, which means you have to flash at least the GPT and bootloader. The lack of a serial number and the generic identifier implies you have not been able to flash an actual GPT and bootloader. Also, OEM_locked is normal until you get an actual bootloader flashed over the blank flash bootloader, which usually means trying to flash a GPT and bootloader at least as new as the latest version you had on your device (regardless of downgrades).
I'd suggest downloading the latest Nougat stock ROM we have from here. Do not use any of the scripts at this time.
https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
Unzip the file, delete any old stock ROMs from your ADB folder and copy over the new stock ROM. Try to flash just the GPT and bootloader then reboot to fastboot. See if you reboot into a fastboot screen with details.
If you do, I would proceed to flash the rest of the new ROM without locking your bootloader. If your device boots then, then you can reflash with the locking commands.
Edit - also, this post probably is better suited to the Q and A section...

The files in mentioned firmware did the trick. It flashed GPT and Bootloader and showed the needed info.:highfive: After that I flashed the same firmware via fastboot commands and device has booted to the stock 7.0 - Bootloader Unlocked. How crazy was I to ignore the proper files to flash? I probably tried 100 times to flash files (wrong once for sure). Thanks alot though for providing the link and instructions. :silly:
Now one last thing, should I flash OEM_Lock file to lock the bootloader so that I can get the lastest Oreo update? I might even think fo selling the device after locking the bootloader. Need your genuine opinion on this as well.

Eh, you live and learn. Besides, you've now got your device running now!
Honestly, it's up to you. Having a locked or unlocked bootloader will not affect your ability to receive OTA updates - you should still receive updates so long as your firmware matches your software channel (and since your device was XT1643, the NPJS25.93-14-18 April 2018 security update should be the correct firmware). At this moment in time, you'll have to use the NPJS25.93-14-18 firmware to re-lock your bootloader - we don't have the stock Oreo firmware at this time. Thus, if you update to stock Oreo, you will not be able to re-lock your bootloader until you can get a leak of the Oreo firmware.
If you're selling, I'd choose to re-lock the bootloader. Else, a potential buyer who is not used to flashing custom ROMs might wonder if there's any tampering with the device (the bootloader unlocked warning, to someone not used to flashing custom firmware, might scare off potential buyers).
Back to Locked Bootloader, complete stock.

I am back to Locked Bootloader as feel the same as you said that anyone buying might get scared by looking the warning sign. Thanks for helping out. :highfive:
Oreo Update via OTA has already started rolling out as per the news I've been reading. I just wanted to see the oreo 8.1 before I sell the phone.
Anyways I got a new device now, Realme C1, 3|32GB as my smartphone usage has declined a lot recently and might remain similar. This device will suffice my requirements.
Thanks for the help and support. :victory:
I did something stupid while trying to restore my phone... I forgot to Enable OEM Unlock before I flashed some boot images and now the phone constantly boots into the boot unloader screen with only two options: Restart or Power Off.
Is there a way to flash firmware on my LG V35 from fastboot?
Edit:
So far I was able to get it into 9008 mode and flashed the abl_a, abl_b, laf_a, laf_b, boot_a, and boot_b files that I had backed up before unlocking and rooting my device.
It seems no matter which img files I have on the device it will forever just boot up into fastboot mode.
Edit2:
It appears most of my problems are because I didn't enable usb debugging and didn't enable OEM Unlock... Not sure what to do from here or who to contact
So far I was able to get it into 9008 mode and flashed another abl_a and abl_b and boot_a and boot_b that I know works, but it still keeps booting into fastboot mode and won't let me turn the phone on.
Yeah I know I'm the only one who posted and commented. Story of my life. Always talkin' to myself.
Anyway. Found a guy I highly recommend that helped me fix my phone remotely.
You can find him on facebook here.
He's in Vietnam, so be aware of time difference. He only asked $20. I gave him $35 because I was so happy with his help.
