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

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

OEM Locked, and Device is corrupt. Unfixable?

So, long story short I recently decided to try and root my oneplus7t I unfortunately made some mistakes and somehow corrupted some files. I read elsewhere in the forum that I could download the stock rom which I did and then use flash-all and that would allow me to go back to the factory settings so I could lock the oem and just go back to normal because I was tired of the headache. Unfortunately, after using flash-all I locked the oem thinking everything should be stock and it would work properly. But it says device is corrupt and trying to unlock the oem says oem unlocking is disabled.
So did I just completely brick my phone? I don't know of anyway to fix it at this point :/.

Can you still boot into bootloader via the hardware keys, whatever that combo is on the 7t?
Boot to bootloader or recovery and factory reset it or so.

I can get to the bootloader but it's Device State -locked and when I tell it to boot into recovery it says the device is corrupt. When I use fastboot to oem unlock it says I cannot, and I can't flash when oem is locked either.

Try
fastboot erase userdata and
Fastboot erase cache
Let me know if that works or not we will move on. Probably won't work since it's bootloader locked
You may have to contact OP and while you're at it, get the MSM tool for us all :good:

It says erase is not allowed in locked state . I think this is probably all she wrote for this one. I think I'm just going to send it back tbh, the whole reason I was trying to root it was because it didn't work with Sprint like they said it would. and I was wondering if I could find a way too make it work with custom software. Thanks for trying

Are you able to flash one of these Fastboot ROMs?

Maybe Sideload can work!

I unfortunately no longer have Twrp installed as I did a flash-all with a stock rom already . If I try and flash recovery it says "flashing is not alllowed in lock state". Sideloading wasn't functional back when I had twrp either as the functionality for it is still in progress. I'll probably try contacting support one more time and see if I can get a T2 who can unbrick it, otherwise I'm just going to send it back. Thanks for the attempts guys!
Edit: As to the flashboot roms I flash-all'ed one of them and that's how I got into this mess :/.

I ended up needing to flash the fastboot 10.0.3 firmware and was able to do a local upgrade to 10.0.4 that way, then flashing a patched boot.img via fastboot

I can't run any flash commands as my oem is locked. I don't suppose there's anyway around that?

How did you flash twrp with it oem locked??That doesnt make sense

I had twrp on it when the oem was unlocked, I was trying to reset the device to stock, so I did a flash-all and then oem locked it. But for some reason the repair was unsuccessful, and now it says my device is corrupted and I forgot to turn on oem unlocking in the settings on my phone after the flash-all before I did the oem-lock.

You should have no issues reflashing the stock images

I cannot flash anything. Because my OEM state is locked.

Looks like you will need the MSM tool to fix this issue. You'll have to contact OP support and they will remote in your PC, load their software and flash it 100pct back to stock.
Also, disconnect them before they can delete the MSM tool so we can have it here in the community

Press volume up/down and power, reboot to fastboot. Unlock bootloader again. Install update from settings, reboot and install it again. (local install)
Factory reset in setting, reboot fastboot, lock bootloader. Reboot and untick unlock bootloader in developer settings.

Don't know if it's too late but I believe there's a working MSM tool now

Bootloop and unable to reflash stock ROM

Hello,
I have a Redmi Note 8 pro (China version). I unlocked the bootloader and flashed the Global ROM. Unfortunately, the phone didn't reboot and it is now stuck with message "this ROM can't be installed on this device".
I realized afterwards that many other users had the same problem. Now it is impossible to flash the chinese Rom again (I get the CRCLIST flash error).
I believe my only option now is to re-flash the China stock ROM using the EDL method and an authorized Xiaomi Account. Can anyone help me do that?
If anybody has other suggestions, that would be really helpul.

You may flashed lower version of miui. If you can enter into fastboot mode, flash with latest China miui, then install TWRP, then use TWRP to flash global rom. I used twrp here and it works for my china phone, now im on global rom.

Just my 2 cents:
1. Always flash stock ROM via fastboot. ALWAYS use option "clean all". NEVER use option "clean all and lock"
2. Make sure the ROM's folder path is not containing space characters. Several stupid errors can come from this.
Ex: C:/this_is_the_rom_path
3. Use USB2.0 port from your PC. Better plug the device into USB2.0 rear port.
I couldn't make any of my USB front ports to work. Only the USB2.0 rear port.

Unfortunately I believe that's precisely the mistake I made... Now the bootloader is locked again and I cannot unlock another time because I have no access to the phone. Mi Unlock Tool says "please add your account in developer options > Mi Unlock Status".

What happens next then?

Thanks for the advice. Unfortunately, I believe the bootloader is locked again now. I can put the phone in fastboot mode, but I cannot flash anything (not allowed in locked state).
If anyone knows how to flash with EDL method... But of course we would need an authorized account to do that.

I remember mi unlock tool will work in fastboot mode. I recommend you to use mi unlock tool which you used first time to try in fastboot mode. It may say: you need to wait xxx hours, then you have to wait. Or it may unlock directly like first time. Since you unlocked first time, it will be bounded into your Mi account already.
If you have fastboot mode available, do NOT too worried, more likely to you have it back. using SP Flash tool with paid auth account is last step.

Could you fix it?

i have the same issue of not able to get into recovery but able to go into fastboot while trying to boot normally just gets stuck at logo phone is able to charge. Showed to a local repair shop who says its a power ic issue searched web where someone mentioned about issue w flash memory (this was for some samsung phone not sure if it applies to mi). I have no clue does anyone know how i can eliminate some of my doubs step by step?
1. I think it may be my power/volume button strip but i dont know how can i test thee device without the strip (i have some schematics) .
2. Maybe Rom issue and since bootloader is locked and no usb debugging enabled nor i can unlock it using official tool since it requires me to go to developer settings and link my mi account i cant flash anything (though i came across some posts claiming you can bypass edl authorization using 2017-18 flash tools and anti5 test i dont have a clue as to what to do).
3. due to recent conflicts i cannot access mi india forums and nor can download proper official stock rom( since its my relatives phone i dont know what version it was on )
4. the phone was dropped previously which cracked the glass but was in working condition for more than 3-4 months atleast .Cant find any trace of water damage inside.
5. got some schematics from web by searching here and there but i dont know how to troubleshoot lol.
Any help would be appreciated , i cannot trust local technicians as there have been past incidences of missing parts from device after they keep for a day and return next day(skeptical if there are some parts missing or replaced w defective ones ).
Will update if i get it working.

Elite OS. Was unlocked.

Does anyone have EDL access that would be willing to save me?

I gess u used MiFlash tool if u locked ur bootloader (clear all and lock), so I guess again that u flashed an stock rom (since MiFlash tool works with fastboot stock rom only). That means that ur not on Elit ROM anymore but in a stock ROM. If u can access fastboot as u claimed, try to unlock ur bootloader again....maybe a miracle is happen and it will work without bonding ur account to ur phone In this stage, u can not mess up ur phone more, so give it a try

Try to unlock bootloader again. It should be possible if you unlocked bootloader before.

It doens't work, it asks me to do the old adb, i can't get in the phone to enable unlock.
but yes, i did...rookie mistake, poxy thing shouldn't even be there and now Im more screwed than ever

Personally didn't contact him, so you have to risk it to verify, and high chance to charge you some repair fee.
If you think everyone who offers EDL but request payment is fishy, then your only choice is Xiaomi repair center.
In your state, chances for EDL access free of charge is extremely low, even non-exist.
If you want free of charge, then try Xiaomi repair center. There's chance for free repair, that is, if your device meet the warranty coverage policy.

I had a similar issue with a Motorola. I tried this, so no promises...but generally I think it's "hot booting" the boot image. I ran the command:
fastboot -b flash boot boot.img
It returned some output like "downloading..." and something else. Of course, locate and put your matching boot.img file in your fastboot directory before flashing. Afterwards, my phone booted into the system like nothing was wrong. I suppose it didn't make it to flashing the system partition? which left it bootable?
Please, corrections, I'm uh, new <----.

You cant flash anything via adb if your bl is locked -_-

If you have an f3 and flashed a fastboot rom you shouldn’t get any issue!! There is a little tool to switch to edl from fastboot , but even having access to that you need a verified mi account to flash or pay someone , its around 25$ had the same issu 7 months ago i can provide you the contact of a legit guy who did for me

I think you have to first put your phone in edl mode by opening the case (melt the glue using a hair dryer) and shorting 2 pins. You should start worrying about edl credentials after you have done that.

Yes, apparently you can. My bootloader was locked when I input that command. The phone then booted into the normal system. You have to have a matching boot image though.
