Your device is corrupt. It can't be trusted and will not boot

Hi friends
Please give me suggestion or guide how to solve problem about handset booting after mistakenly handset OEM locked through fastboot
It enter to fastboot mode but not going to recovery mode or restart in system mode
Is there any solution
If yes then please help me

fastboot oem unlock ?

Actually ive unlocked OEM and install twrp recovery and installed freedom os
Then while checking OEM status ive enter command fastboot OEM lock
It ask me I've pressed yes after that the massage is came after restart as your device is corrupt it can't be trusted and will not boot
After that it enter to fastboot but not going to recovery mode or system
While type command in fastboot OEM unlock massege come failed

This happens because your bootloader has been unlocked at one time. There is no going back, even if you use "fastboot oem lock" later.
Edit: Just noticed the part about your device will not boot. You need to find the system image and flash it. I read somewhere today that OnePlus just released the system image for 4.7.4.

Can you unlock again?

@op, IMHO the best possible solution will be to flash stock rom image and stock recovery if required but I think when you flash stock image it will also flash stock recovery.

When you turn off the phone and boot it with VOLUME UP plus POWER, this should send you straight away to Fastboot. Try if you can unlock again, otherwise... bad luck - you'll need a restore session with 1+.

Not to be unrespectful, but you're wrong, it is absolutely possible to relock bootloader without problems.
IMHO, trouble happened because he had a custom rom onboard... and a locked bootloader does exactly its purpose... to not boot insecure firmware!

After looking into it further, I agree with you. That's what I get for having a bootloader-locked Samsung device for two years. I must be getting rusty!
Yes, the bootloader can be re-locked. There may still be a tamper flag as with previous OnePlus devices. But having a locked bootloader with non-OEM software would likely cause the problem he is describing. So, he needs to flash the factory image from bootloader.

I've requested to 1+support for restore remote session
Support send me file link and l2 will assist me in within 2 days

DO NOT RELOCK BOOTLOADER UNLESS U READ UP FIRST!!!!!, its worth just waiting the few seconds after reboot, then to go and try to relock the bootloader

Have you dumpling files and MSM download tools for oneplus 5t
If you have then restore op5t after success it work as new mobile.
But you can get basic dumpling file from oneplus support remote session.
You have to create ticket and chat with oneplus support

Did you by any chance re-lock the bootloader with a custom recovery and custom ROM flashed?

It's because of custom recovery.
Just flash stock recovery image before locking the bootloader.
This fixed for me.

You unlocked bootloader, flashed rom (custom) and relocked bootloader? Never lock your bootloader on a custom rom! Just enter fastboot again flash twrp (manual/force reboot recovery), copy internal storage to pc then wipe/format everything. Format data. Factory reset then flash latest official rom and reboot

I am bricked my phone

bootloader unlock code different from frp unlock code.
installing other device firmware has chance to replace oeminfo.img partition. Changing this partitin often causes locked frp.
If lucky you can wipe from the erecovery that is loading. maybe even couple times. Then maybe it will boot. Other that that there has been no public mention of any fix.

do your best to fix it using hisuite or other methods if you can. if you have twrp that can help if you have stock recovery and locked frp your only hope might be hisuite and if that fails you will need a paid option like dc-phoenix or funkyhuewei. i only have experience with dc-phoenix, and it did fix my locked frp completely bricked phone, but i read that funky also works well but is nearly 3 times as expensive. (15€ vs 50€)

The displayed build number comes from the data part of the update. (Update_*hw_*.zip)
If you reflash again all three files , might be fixed

If flashing again is the answer to solve problem. Use my guide here.
You are on Oreo now so use the top portion. "Flash update"

I don't want to sound like rude or anything.
But I put it all pretty simple, I thought. Like 4 steps
Download files
Put files on SD card
Install twrp
Install file I shared
If that is over your head, maybe you should not have modify and phone.

Update a locked P20 with stock roms

Hi to all,
i have a P20 branded (and with bootloader locked), with verey delayed software updates.
I would like to if i could update it using the roms downloaded through Firmware finder, and which is the procedure, since i tried to download the latest update.zip found on FF, unpacked in the dload directory of my phone, rebooted on stock recovery (vol up+vol down + power) and had a generic error.
thanks a lot for your informations.

Packing yourself a 'non-working' dload with extracted update.app from original firmware found on Firmware Finder won't work...
To force an update with a locked bootloader, you could :
-Try to update with FirmwareFinder's DNS, Hisuite 5 and an IMEI-approved OTA-MF ; You'll be updated without any userdata erased.
-Use a working dload firmware for your model and cust to update. Download said dload archive for free from http://androidhost.ru ; Your SDcard or your USB-OTG must be ExFAT formatted for dload update to work !!!
All your userdatas will be erased this way.
-Buy your bootloader's unlock code online from a third-party. Unlock your bootloader. Install a working twrp custom recovery. Use HuRUpdater with any updated firmwares for your model and cust you can find with FirmwareFinder. You'll be updated without any userdata erased.

Working dload archives should upgrade fine with your model's and cust's archives.
Working dload archives should downgrade fine with unlocked bootloader.
Only some users are reporting successfull dload downgrades WITH a locked bootloader on SHT and CMR for now. Most fails.

I would not keep locking/unlocking the bootloader unless you want to brick your phone.
If you can get to the bootloader, flash-all the latest factory image #4 'Keep data' in this guide: [Guide] Pixel 3 XL Android 9.0 (Pie) Unlock/Root/Install Images/Kernels/Recovery + by homeboy76
Then look at #11 in the guide.

- There is also no 'fastboot' nor 'adb' in your Platform-tools folder.
First, download the latest SDK Platform-tools r28.0.1 from here.
Then read #4 again, pay particular attention to #4B.

From your first post:
"when i couldn't install the new update i wanted to lock the boot loader again and i locked it by typing fastboot flashing lock and of course the device did't boot up"
You got lucky, you locked it and it bricked. When that happens and you are locked you can often end up on a situation where you can't unlock again.
So I said what I meant, stop locking your bootloader unless you are 100 percent stock and working perfectly.

System Update Failed? Here is Possible Fix

This Is For those Who Stuck At Android 9 In WW Roms With ZS660KL Model
This Method Will Use Raw Firmware so there is risks if you do something wrong and maybe data loss so always backup​Bootloader Must Be Unlocked
How To Flash Raw Rom:​1-Bootloader Must be Unlocked! (To change fingerprint to ww and relock the bootloader to get OTA) If you are already on WW fingerprint this step aint needed or you want to stay on cn fingerprint just skip)
2-Install adb and fastboot
3-Download and extract the raw version you want i will give some below
4- reboot the phone to fastboot mode and connect it to the pc Use Side Port
5-in the raw firmware folder double click flashall_AFT.cmd This will take sometime and no progress will be shown so all you have to do is to wait till the phone reboot or get black screen if you got black screen just hold vol down and power button for some seconds
6-if your Fingerprint is cn Change it to WW With root explorer you can find posta about this step by step (skip this if you are already on WW Fingerprint)

or you can install update zips from asus if you want to keep bootloader unlocked :silly:
