Hi Everyone,
Does anyone have any instructions as of right now on how to recover a potentially bricked OnePlus 3? Doing some googling around yielded me to the conclusion that my OnePlus 3 bricked itself.
Thanks!

Contact support.... you're the first one with a bricked device....
And it would be great if you could share the support e-mail.... it would help me get unbrick files for this device

Fastboot on op2 is already a mess and we don't have enough info of what could happen in op3... best avoid fastboot except for flashing twrp
Flash the stock ROM through twrp

Your oneplus bricked itself?
are you sure there wasn't a human involved in the process?
As other people says, you're the first one with a " bricked" device, so please tell everyone what your device status is, and how it got bricked.
did you unlock bootloader, did you have root? as much info as possible..

Why a mess?
Fastboot itself is very simple.
fastboot flash <<partition you need to flash>> <<file patch>>.
Is it different from the "common" fastboot we can find on a Nexus?
When I try to do this I get the following message:

And have you enabled OEM Unlocking in Developer Options ?
BTW Please reply to my PM ASAP if possible.
Thanks.
Best Regards,

I can't OEM unlock in developer options as I no longer have access to my device
PM answered
Experiencing the same problem here.
I had the same in other thread. OEM unock was disabled. Do You have working stock recovery or TWRP? If stock works You can flash stock rom by ADB sideload.
My bootloader is locked so it's showing FAILED (remote: Partition flashing is not allowed) and cannot get into recovery.

try this:
http://www.androidbrick.com/unbrick-oneplus-one-two-3-qualcomm-hs-usb-qdloader-9008/
you need the OnePlus3_Unbrick_Tool_Full.rar to unbrick your phone, i was also in your situation,
you need also the Qualcomm_Diag_QD_Loader_2016_driver.exe with this two tools you can flash to restore the OP3
me helped al lot this thread http://forum.xda-developers.com/onep...icked-t3405700
a had a success with this part How to Make the device show as Qualcomm 9008
it is important that you have the correct driver installed on your pc that the phone will be recognized as Qualcomm 9008
I did the exact same stupid thing... locked bootloader before flashing stock recovery.
This post saved me:
https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/
I used method 2 in the post which wiped everything but at least i got the phone back.

Since im a new member I cannot post links so ill have to give you directions.
Search google for Hard Bricked OnePlus 3 and it will be the first one called Mega Unbrick guide.
Use method 2. Ive used it multiple times when flashing goes wrong on my oneplus 3.
Another step, download the latest stock recovery from OnePlus and name it recovery.img and replace the one in the folder. You should understand more when you have all of the files.
You can download the latest recovery from OP at the bottom of the page linked here:
Google OnePlus 3 beta download and it should be the first one saying community build.

You are trying to flash TWRP with a locked bootloader and it obviously fails. Download the full official ROM from OnePlus site and the corresponding recovery also. First flash the recovery and reboot to bootloader and then flash the OS and reboot. If you are successful, you can enable Developer Options and from there OEM unlock and USB debugging. Thereafter you can try TWRP, Magisk and other ROMs.
Hmm, I thought he said he can enter bootloader and recovery. If so, reboot the phone in stock recovery and flash full Rom from local update.

NO.
So that is where you are committing a mistake. You have not been reading the posts carefully.
All of us are asking you to download the STOCK recovery compatible with the version of the stock ROM chosen by you and to FLASH THE STOCK RECOVERY FIRST, NOT TWRP.
Because TWRP can't be flashed with a locked bootloader whereas the stock recovery can be flashed from bootloader. Then go for the ROM, sideload it using adb and boot.

I'm trying to unlock lenovo z2 plus bootloader using adb and fastboot on fedora. I'm using platform tools version 29. I'm trying
fastboot -i 0x2b4c flash unlock unlock_bootloader.img
but this command won't work. I get this error message
fastboot: invalid option -- 'i'.
Apparently fastboot --help also doesn't shows -i as an argument.
So how can I unlock the bootloader?
Ignore that i part,
Just use fastboot flash unlock unlcok_bootloader.img
According to my experience, under Qualcomm's EDL mode (9008), it can actually flash TWRP without unlocking the bootloader.
"fastboot oem reboot-edl" or "adb reboot edl" will reboot the phone into 9008 mode. You may try special EDL USB cable as well, especially under tricky situations.
You need to download (and install) qpst 2.7.474 and stock ROM (for prog_emmc_firehose_8996_ddr.elf). QFIL has a nice partition manager feature, which allows you to flash anything you want - of course, this will introduce risk of data loss/bricking etc, if improperly operated.

These are for older version adb commands so you are facing issues either use older adb files or use new commands

Ohhh no that seems bad I just received my z2 yesterday for sake of custom rom and rooting.If this does not work out, I have to refund it ASAP.
Please follow this thread and reply if anyone got the unlock file
Finally this thread https://forum.xda-developers.com/le...-receive-unlock-bootloader-img-t3731061/page4 Post Number 40 helped me unlock my bootloader as of 16th November 2019 and now I am on custom ROM
didn't need the file at all
Phone: ZUK Z2 Plus (Z2131)
After having tried many times following this tutorial and never receiving any E-Mail, I found a rather simple solution that worked:
I didn't really expect it to work, so this is from memory, wordings may differ a bit.
First: make backup of your data!
Make sure you have updated ZUI to the latest available version.
Enable developer options ( From your device go to " About -> ZUI version" , scroll down and click " build number " continuously until you see "You are now a developer")
Go to developer Options and look for the toggle "Allow OEM Unlock" (or similar) and set it to enable. Confirm.
Reboot.
The phone automatically performs a factory reset (All Data lost!).
Now you can continue with flashing custom recovery (TWRP) and ROM.
For example use Lineage OS. Instructions: (Sorry, can't post the link) go to lineageos.org and look for the decive and go to install instructions.
Finally I can enjoy the phone with custom ROM and up-to-date Android 10.
You may have to be on ZUI 3.5 (Chinese Version) - It may not work with the Indian Version.
Follow this hints to deep flash ZUI Chinese Stock firmware: https://forum.xda-developers.com/showpost.php?p=83808887&postcount=2

From ZUI 3.5.xxx on you don't need unlock_bootloader.img anymore.
You need to allow OEM unlock in developer options first, then just unlock by "fastboot -i 0x2b4c oem unlock-go" .
If you did not allow OEM unlock option in developer setting then you get error message.

always like that , i've tried to get new img but still like that.
I've tried to unlock my device with enable OEM unlock in the developer options, because it is needed for enable VoLTE in my regions(with QPST). But it seems that device doesn't recognize it's allowed to unlock. Every advanced fastboot command in fastboot mode returns "FAILED (remote: 'Command not supported in default implementation')".
Is this possible to you who using the device to unlock the bootloader with fastboot? Or, OTA updates I've received blocked that?
How unlock the bootloader?My HTC U20 5G no download mode in bootloader !!!!!
Try
fastboot oem get_identifier_token --- error
fastboot flashing unlock --- error
fastboot oem unlock --- error
Yes I have the same problem. I thought it was Win 10, so I tried Win 7 as well, but got the same error there too.
Check if "USB debugging" and "OEM unlocking" are activated in Developer options

Yes, both options are activated (at least in my case).
Both commands "fastboot flashing unlock" and "fastboot oem unlock" result in "FAILED (remote: 'unknown command'), fastboot: error: Command failed".
I have no problem with Desire 20 pro and have no guess why it doesn't work with U20
C:\adb>adb reboot bootloader
C:\adb>fastboot devices
CN06D1V02*** fastboot
C:\adb>fastboot flashing unlock
...
OKAY [ 0.040s]

It also works with the U19e, very annoying that they changed it.

for anyone that might come across this problem. I had the same issue trying to use fastboot to relock my bootloader. Found the answer on another forum. I was using adb to reboot to fastboot mode to run the command. This was the problem. I needed to reboot to the bootloader to run the command

Try rebooting to the bootloader screen instead of directly rebooting. This solved my problem.
Hi there,
Just wanted to check in and see if anyone has managed to get bootloader unlocked?
Or is the htc u20 out of luck....

Hi, Just manually enter the fast boot mode with power key+Volume Up or Down depending upon the model and make, You can search this online how to enter Bootloader mode for one particular device. Once you are in Bootloader, Try Fastboot mode and Enter your commands. Should work
Anyone figure this out on Nord n200 5g T-Mobile variant? Please help
