Hard Brick Poco F1 - Xiaomi Poco F1 Questions & Answers

Hello!
Im green in topics of roots, ROMs, flahshing, etc, but i was trying to solve my problem which is bricked soft. I never flashed anything or pick at soft. After android auto update my phone started lagging, and when i drained my battery to 0%, I have reach an impasse.
I was digging this forum to get some clues how to repair it by myself, but i get to the stage where i wonder if its even worth rescuing my poco.
Here's the deal:
I have only acces to fastboot, but my bootloader is locked. There is no possibility to unlock it by miflash_unlock. I have authorized MI account but i hadnt enable unlock in dev options in menu. So when im trying to unlock i get error that i should enable this option which is impossible in these conditions.
Is there any possibilty to bypass locked bootloader? I had read about EDL, but cant find any tutorial for poco. Also i havent special cable for that.
Now im wondering if i should go to GSM point and get them paid for unlock this, but i wanted buy new phone anyway at black friday. The cost of repair wouldnt be higher than selling this 3 years old phone?

The LG L52VL from ST/TF

OK, So I purchased this LG Treasure about a month ago and of course. I'd like to root it, Problem is Tracfone has this thing locked down tight. the bootloader/Recovery is not accessable. If you do the volume down/power button combo, it only brings you to a Factory date rest option. . I went to LG support and had a chat with them. I was informed by the tech that the bootloader access has been disabled. I asked if there was a way to enable access and he said that there is a way but he is not allowed to tell me and suggested that i come here to inquire. So i am hoping some here might be able to help, I don't even care if brick this device , it's worthless as is. Adb will see the device but fastboot will not leading me to think it's disabled by the carrier as the tech suggested. So any help would be greatly appreciated. Some one please point me in the right direction with anything i can try . Thanks All.
thank you..

Thank you so much for posting this question as I have that same issue. Your question was well put. Yet no one has responded. I hope there is a solution to this issue. :good:
these questions regarding the rooting of the lg treasure, which is my phone ironically, brings us to 1 definate answer, and that is that tf already knows how to unlock the bootloader, and thus, root the phone. it seems logical if any other tf/st phone has a similar os/locked bootloader that has been rooted, we might try those, or find someone recently seperated from the employment of tf who may spill the beans perse. just my input.

Thank you for giving me some hope lol. But still I have had no luck rooting this phone. Pretty aggravating. It's a decent phone and all. Sad they ruin it by locking it.
oem unlock
Did you first go and turn on oem unlock in the developers section of the phone? It is required by many phones under loli to unlock the bootloader. Might need to turn on usb debugging too in order for fastboot to be able to access the bootloader to get root on the phone.
My OEM unlock option has been enabled. However I have had no luck at all rooting this phone. It's unfortunate. Again I'm asking any developers available to please work on this project. The LG treasure is a very popular phone. Not only because of the price, But the features the phone has. Please I have done my best getting this phone to root.. But I'm out of ideas.
I have the lg rebel 2 lte and same problem. There is of course a way, their official unlocking policy is they'll grant us the unlock after a year of service paid. So they charge you for the device then charge you for a whole year for full access to said device. $$$
But lg has an official developer thing now where they'll email you the unlock.bin file to unlock it.
However the only; and I can't stress this enough, the ONLY problem is they've coded the bootloader to skip fastboot entirely. Somewhere between the first and second splash screen the bootloader and fastboot are working, soon as it shows the tracfone logo that's when you know its booting android. I have yet to figure out how to read the logs of the boot process to see how.
Yes, enable oem unlock and usb debugging.
However everyone with a new lg phone under any of the tracfone subsidiaries will find that those options don't matter. There must be a dialer code for the bootloader deal.

Xiaomi Mi Play -bricked by official update

Hello All,
Hope you and yours are doing fine in these worldwide complicated days.
Regarding the subject, I have a Xiaomi Mi Play mobile that was working fine, with official MIUI, never rooted, never done something else than usual "office" daily usage.
One day, came the famous Security Update notification and as usual, I've confirmed.
Since then big headaches...
Next morning I found the phone in the loop reboot, Fastboot being the only available feature, no more recovery, no more OS, no more personal stuff... Everything has been deleted by the update.
When trying to go to recovery only the magnificent message with the red triangle, saying "The system has been destroyed. Press the power button to shutdown" stays for 10-15 secs and then the whole crap reboots again and again.
No, Developer Settings haven't been enabled, OEM Unlock has not been enabled, USB Debugger neither, bootloader has not been unlocked, MIUI account has not been added in Developer Settings or elsewhere... and no I haven't wrote to Xiaomi support yet.
I've tried around 60-80 different methods to unlock whatever could be unlocked on Xiaomi phone, EDL, bootloader, with dozens and dozens of methods proposed, so far nothing worked. Impossible to install anything, impossible to unlock anything, impossible to do anything.
I've applied for the phone unlock, but since 2 months, impossible to finish the process, it says "Couldn't Unlock - Please add your account in MIUI's Settings > Developer options > Mi Unlock Status"
But I CANNOT access the system anymore at all....
This is it...
Thank you for reading and if you have any other ideas out of everything I've tried, feel free to let me know about.
Take care of you and yours
Kind Regards,
SK
ooophhh no. did you ever get a solution? i had my mi play brick just oputta the blue.. its on communist lockdown fighting the war on capitalism ..... well the hardware wasnt bad for the price and it ran well.,but im not buying a phone from them ever again.
It's very sad. Did you get any update?
Hello All,
No update since March, still looking and trying to unbrick the device....
I'll keep you posted if I find anything that could be called a solution.
Thanks for your support.
Be safe all, you and yours.
Kind Regards,
SK
Same here, bricked device since March by the same update, "The System has been destroyed", fastboot doesn't load.
I guess i've lost 150$.

There are many thread for issues like this, for example:
https://forum.xda-developers.com/mi-9-se/help/lock-bootloader-destroyed-help-t3965825
It seems that in some way, same issue was fixed on a different model, but most likely it will work also with Mi Play.
Af far as I have understood, basically the solution is to download the official firmware and flash it back. The main issue is that by default the bootloader is locked so nothing can be written. The point here is how to unlock the phone, and there is an official procedure from Xiaomi:
https://forum.xda-developers.com/mi-9t/how-to/guide-unlock-bootloader-flash-xiaomi-eu-t3952443
I have the same issue for a couple of hours and I am struggling now, so as first step I am trying to unlock the bootloader, but the problem is that per Xiaomi instructions it may take up to 7 days.
So, I will apply for that, while in the meantime I will look for any alternative solutions (if any).
Regards,
Thanks a lot!
But, the're now way to get my phone into fastboot mode.
I've tried all button combinations and there's no response, just the same loop "your system has been destroyed"

After some tests on my device, I have found out that it's not easy as I have believed, but if you don't get even in Fastboot mode it's more complicated.
However, can you please clarify what's your cellphone model?
Regards,
I have exactly the same problem since early May, if I just unlock the boot loader before they fall down :c

Cannot add mi account to mi unlock status to unlock bootloader

Hi
I want to unlock my Pocophone F1. I enabled developer options, activated OEM unlocking, USB debugging and created an xiaomi account. However, I have a problem, when trying to add the account to mi unlock status. I keep getting the error: Couldn't add. Device does not exist in the server
When trying to use the mi unlock tool, I get the message to add my account to mi unlock status when I'm at 99% which I can't due to the error above. Tried serveral versions I found.
I have a sim card inserted, tried logging out and back, even factory-resetted the phone but still getting the error. Already waiting since 3 days. Does it help to wait a few days more or is this just waisted time?
My Pocophone F1 is brandnew. Could this be an issue?
Thanks.

Hello,
Did you followed the Unlock Bootloader guide in my thread?

Yes, but there isn't really much to follow because I can't get past step 5.
Well, that's kind of frustrating.
I've tried pretty much everything with no success. I wrote to Xiaomi customer service and they basically told me that they will not help me because unlocking the bootloader is not a typical customer service (I thought unlocking the bootloader is a feature of this phone as they provide an official way and tool for it). They also told me not to do that for security reasons and that I will void my warranty (although that's not true afaik - I don't care about the warranty anyway). I don't know if I'm allowed to post the content of the mail, but there isn't any other useful information in it anyway.
I'll try again occasionally over the next two weeks or so and then just sell it. Unfortunately, the back of the phone has a very small, almost not noticable scratch, so I don't think I can return it to the store where I bought it (the phone is only a week old).
Too bad, I really like the hardware, but the phone is unusable for me with a locked bootloader. It's like buying a TV, but the TV only has one channel and you're not allowed to change the channel. Well, it's not really the same, but you get the point.
This was the first and last time I bought a Xiaomi phone.
Cheers

Question TMobile variant won't stay in fastboot

Ok , lemme cover my bases here... OnePlus 10t, Android 12, T Mobile. .
I have usb debugging on, oem unlock on, and device appears in ADB ... Newest platform tools, updated drivers.... When I run 'adb reboot bootloader', the phone shuts off, then I see 'fastboot mode' for like half a second , and it goes off and boots up normal. I can enter fastbootd .. but regular fastboot causes instant reboot! Can ANYONE help me with what I need to do? You can't unlock bootloader in fastbootd... So I need help figuring out how to make it NOT kick out of fastboot when I enter the command. (Usb 2.0)
OPPO locked the bootloader permanently. They do this on the find series as well.. basically bootloader mode is disabled.
I haven't heard about this before, is it a T-Mobile only thing? That seems really bad for oppo to do that...

ok , so how then can i either re activate this mode or root this device? because that is a deal breaker for me! I wont keep the ONLY model of this phone that has Fastboot disabled, and therefore is unable to be rooted! I have about 8 days left to package back up and send back to Tmobile for refund! Now i can fully reach EDL mode, so if there is a software that can let me flash the EU Unlocked FW , then please direct me. I saw some success written about here with the new MSM, but it requires some authentication. I am 100% fully committed to any method, no matter how complex, to rectify this travesty! The ONLY reason i jumped from Samsung to OnePlus years ago was because of how Developer friendly they were... Easy unlock of bootloader... yadda yadda! Now the curse of Beatbreaker has struck again, and the impossible has happened in that SAMSUNG bootloaders are now easily unlockable via purchased token... and Oneplus has become part of an asshat dictatorship.
Please advise if there is ANYONE here who can either help me with this situation, or can direct me to instructions/software that can flip this situation around. I mean, the fact that Fastbootd reports my device in "Fastboot" when running 'Fastboot devices' ... AND that even if only for a glimpse of a second i can see FASTBOOT MODE, before it kicks me out and reboots, tells me that there must be some glitch, exploit, or workaround that can re-enable it! I only state this because some phone companies (carriers) like Metropcs were pre-installing FW that made Download mode disabled for quite a few devices, but thru some low level (edl) actions, we were able to reverse that and load a global fw to the phones, restoring all functions!
ok long posts.... ANYONE... I am up for ALL suggestions, because i can fully brick this phone and return it , but my window closes in 7 days!

Dang! This is a messy situation for yah! I contacted support for an MSM tool and they said I have to send it in for them to flash it.
I think trying to have them flash some other variant would take you past your 7 day window and they may not do it anyways.
I would say least send an email to OnePlus support and ask if they would flash to other variant otherwise you will be returning the phone. You should get a response soon. Otherwise I'd lean towards returning it... Sadly.
Then buy straight from oneplus if you still want a 10t. They may have a good blackfriday deal on this phone as well.

i need help unlocking my device after it has had mi account lock bypass

hi. a while ago (5 years ago) xiaomi note 5 pro was gifted to me when I was living in volos (Greece), now I live in athens and found my old device which was stored in storage boxes, I charged it and it works! i wanted to install a custom rom on it as I hate miui and when I factory reset my phone it locked up, I worry as I try countless passwords and none work, and the phone number linked to the locked xiaomi account is a very old one which I changed about 3 years ago and don't even remember anymore, after trying to get a receipt from KOTSOVOLOS (tech shop where the phone was bought) they said they couldn't find any receipts for such phone. without it xiaomi wouldn't unlock my phone no matter what. so I took it to a shop to bypass the lock and they did. it now works but they told me to never factory reset it as the lock will come back.
they bypassed the lock by corrupting the lock partition, and disableing 5 services (found out myself after digging into the phone by my computer)
now, I wanted to unlock its bootloader to flash a custom rom. but when I try to add an account (from the mi unlock status section in settings) on the device (with sim) it tells me error 20091, and trying to do it straight from mi flash won't work either, as mi flash detects that the device is still locked up and won't proceed. after calling the repair shop, they told me because of the bypass they couldn't unlock its bootloader.
but I don't want to give up right now.
can anyone please help me? any suggestions appreciated, and I will answer all questions you all might have (if any).
thank you!
