baseband and IMEi is null and unknown ,
i bought the phone as unlocked sim phone and now nothing success with me
what i should do to fix this problem?

If you can get into download mode, flash a custom recovery to your phone and then flash an old cm11 ROM to see if you can get the phone booted.

which one to use

The way you say stupid is stupid however mine didn't got flashed just rebooted when tried to flash the raw and couldn't update in system updates or zip files however having some respect ain't bad for your health.

First of all, I just said it was a stupid thing to say because you don't need to unlock the bootloader and you must use the side USB c port to flash via fastboot. Second: learn to interpret proper English because I didn't offend anyone. End of conversation

You will need to enter an command in fastboot mode but be aware backup every necessary things
If you didn't rooted or touched boot.img just use this command in fastboot and the bootloader will be locked again

You'll need to flash stock boot img if your rom version (to remove root) before locking bootloader

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.

so sad

have you tried fastboot oem unlock and flash with fastboot?if fastboot isnt working for you, you should try it in linux, this is what fixed my bricked prestigio tablet.
or try the chipset flashing software?
also this: https://forum.xda-developers.com/t/...nload-mode-after-ota-on-rooted-lg-g2.2582142/, and if this doesent work i think you can try shorting the pins on the motherboard to get it into flashing mode, there is always a way but takes a long time researching and trial/error,
im still trying with my device ill post here if i fix it

Question Bootloop to fastboot logo and back in lock state

Hi everybody,
yesterday I tried flashing the stock pocof3 rom back onto my phone, but since it got stuck in a bootloop at the fastboot logo. Showing the poco logo for a milisecond and then straight to fastboot..
(before this I flashed twrp and the arrowOS recovery and images a few time trying, without succes, to install this rom)
Last thing I did was flash via the mi-flash tool and did't see the "clean and lock" selection so it's also in lock state again.
I cant get adb to find the phone although the mi-flashtool is finding it.
anyone any tips?
I tried the vol up power trick, but this didn't help, keeps loading into fastboot

I dont recall giving an error, so i dont think so
now it is though, when trying to flash the firmware. error erasing boot_ab (failed: erase not allowed in lock state)

I'm not sure, but you may still be able to flash official ROMs.
But in "Configuration" make sure Erase is disabled

BAD NEWS... your Poco is bricked. You cannot flash ANYTHING using a PC when your bootloader is locked.
(I did same thing on a Mi11 5g last week and ended up selling it on eBay for spare & repairs
I tried sideload flash, miflash, copying update.zip to internal storage via ADB, and many other options - all without success).
- if your POCO is under warranty in your country (i.e. not a chinese import)... contact Xiaomi Support they can re-flash correct ROM
- Ask your local phone repair store... they *might* be able to flash original ROM back by using "Chimera" engineering software.

this doesn't seem to be an option. there is a checkbox with "erase all" but all are already unchecked

- Bootloader was re-locked whilst a custom ROM was in the phone.
(MIUI with Locked bootloader will not boot up where ROM is not stock or does not match the region/product code).
You cannot apply for bootoader unlock because you cannot boot up into Android and request the unlock via Developer mode.
You cannot remotely (via PC cable) flash any ROM into a Xiaomi / POCO phone whilst botloader is locked.
You are in a chicken and egg situation.,,, but if you find a way to repair your phone, please let us know how you achieved it.
Good luck!

If the system hasn't booted up yet there is a chance that you will be able to unlock bootloader again. Try it.

That's what I'm thinking too ...
Connect the phone to pc and do the bootloader unlock again via the mi unlock app - you don't need to apply again and stuff as long as you're able to recognise the phone inside app correctly

thanks everyone for all the replies!
tried unlocking it via the mi unlock tool (latest) but it says (in chinese) its locked by nr 123***456 by searching the phone - can't unlock
edit:
google lens translates:
X The phone has been locked by the account number 661****647 by searching the phone, Can't unlock
but it's not the nr. of my account..

Is it not even possible to flash Official ROMs?
Isn't there like a system that it checks the signature of the ROM and if it's a signed ROM it allows the flash? Or am I mistaken?

Nope bootload locked = no 'remote' flashes via pc
Apparently there is an 'authenticated user' mode for Xiaomi engineers in MiFlaah and also an EDL Emergency Download Mode which you can trigger by shorting out 2 pins on the motherboard so bypass bootloader lock and flash any ROM
Neither were available options for me

I'm now in the procedure to sent it back under warranty. any idea if this is possible and what the cost would be if not under warranty?
If all fails i'll try the shorting by pins, should be interesting

I think a warranty repair claim is your best bet ... I have never read anywhere that unlocking bootloader invalidates Xiaomi warranty (Unlike Samsung and so many other brands!)
If warranty repair is re refused try a few independent repair shops
Last resort is get the back cover off the phone and short out the EDL pins
Good luck!
Let us know if you manage to get your phone booting up again

I once hardbricked (complete blackscreen, not even Fastboot reachable) a Poco F3.
I requested a replacement from Amazon and that worked.
I said a software update bricked it.
Of course having to do that is really bad, but I was scared of opening the back.
