Phone stuck in bootloop - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hey everybody
My friend gave me his Mi 9t Pro to repair it as he bricked it accidentally and he knew I had experience with changing ROMs and recoveries.
From what I know, what he did is tried to change dpi and then phone jumped into bootloop.
Let me just state that:
- bootloader is locked
- there is no custom recovery
- I have no authorization for ADB
I am stuck and would be really thankful for any ideas. Wiping data is not an option at the moment as we want to recover data from the phone.
Dropping battery to 0% and then charging didn't work.
Adb is only possible at the very short moment phone gets into boot animation, but as I have no authorization I can't pull files from it.
For whatever I tried ADB sideload when connected with Mi Assistant in recovery didn't help me neither.
If you have any ideas please share them with me, I'll appreciate that a lot

I can't see any way you're going to keep the data. Recovering the phone is going to wipe everything. Without an unlocked bootloader I can't see any way your going to be able to access the data first before restoring the phone.
As far as restoring the phone, if you can access the official recovery, then you should, hopefully, be able to flash an official recovery ROM from there, or so I believe, I've never actually tried it.
If that fails, then you will need to EDL flash the phone.
This involves taking off the back to put the phone in EDL mode, then paying someone, who has an authorised account, to remotely flash the phone for you.

Yeah, that's kinda hard situation :/
I can't really flash recovery ROM, cause official recovery has no option for that and adb sideload didn't want to install 'update.zip'. just rebooted the phone and that's all.
I've seen that it's actually possible to put device into EDL without having to disassemble the phone, but fastboot command just reboots the phone.
Thanks for answering either way

Have you tried updating ROM through Mi PC Suite (latest version)?

I tried through MiFlash, but it only allows fastboot ROMs, and because bootloader is not unlocked I couldn't flash it. But that's a good idea, I'll try Mi PC Suite, I'll let you know how it ends.

I tried, but seeing that mipcsutie is same program as mi assistant, I cannot do anything because it doesn't recognize my phone.

Which version? I'm using https://c.mi.com/thread-1015363-1-0.html on Redmi 6 (locked bootloader & bootloop) and successfully restore. Make sure you've correct driver installed.

Because not possible if your bootloader was locked to enter EDL mode, then AFAIK you need Mi Account with authorization to flashing with EDL mode.

Are you talking phones in general, or this phone specifically. For this phone the only way is to take the back off and do the 'Test point' method. I've never heard of anyone successfully entering EDL mode using any other method.

ADB sideload needs the phone to be put into ADB sideload mode first, so to speak. This is why you have the ADB sideload option in TWRP. You don't have this option in the standard recovery.

Also make sure you're using a good USB cable and also try a different USB port.
Also try using your friends PC. I assume they have previously connected the phone to the PC successfully before, so they should have the correct drivers already installed.

If you connect via 'Mi Assistan' option in recovery the phone connects to pc using adb sideload.
I tried different cables and ports, and I have correct drivers.

In this case your only option now is to EDL flash. Sorry. Search for guides on how to do this, within these forums. XDA admins have been removing contact details of anyone with an authorised account, who will remotely flash for you. These people charge for doing this, so it's against XDA policy to give details of people who perform paid for services. You will find recent posts from people who've got details of these people who can EDL flash, that will kindly allow you too PM them for details of such persons.

AFAIK, USB debugging not required just adb sideload to work.

Have you tried looking at the .bat files miflash executes from the fastboot images. You can flash system etc.. without dating perhaps this will reset the dpi

Phone bricked after an OTA update

Sorry, I didn't know where to post this, but okay; I've installed an Oxygen OS update two days ago and I've had my phone rooted, my phone has been bricked since. Whenever I enter the bootloader my device isn't detected anymore by my laptop therefore I can't re-flash TWRP and now I'm completely stuck and don't know what to do, any help please?

You're best bet would be to download the full OOS OTA and then ADB Sideload the OTA.
You should find all the files you need on*
http://downloads.oneplus.net/
First, you download the full OOS ROM and the stock recovery for Nougat.
Then you flash the stock recovery (fastboot flash recovery <file name>).
Then you boot into recovery and select "install from USB" to get into sideload mode.
And finally you sideload the latest OOS (ADB Sideload <filename>).
It will take some time, but your phone should work after it.
FYI, keep in mind that you'll have to manually flash updates when using a custom recovery
Hope this does the trick for ya!
Good luck and happy flashing!

Assuming you have ADB on your laptop, does the command "adb devices" list your device?
I think your problem may have been caused by attempting an OTA update while using a custom recovery. I have learned this is not recommended.
Try and connect with ADB and if you can follow the instructions to sideload given by the other member

It only lists my device when I'm in the booting process. Everywhere else, it does not
Use the usual Qualcomm recovery solution, it will work as long as you hold the buttons correctly and don't power it on, else you will not end up in Qualcomm preboot mode.
It's just like MTK recovery on Mediatek phones if you've owned one of many MTK-devices. ?

Yeah follow the unbrick thread
I just updated my own thread that has ULTRA-BRICK in the title a second ago for how I solved my issue haha
edit: if needed, can PM me too. I won't hold your hand, but since I just came out of the worst brick I've ever managed to do to myself, I might be able to help if you encounter the same things
Also brick is a misleading word, as you can't really brick this phone unless you tamper with other partitions than the visible ones, which nobody does as they don't see them. ? (unless your tampering with firmwares or trying to unlock frequency bands)
Alright guys, I solved it. I just had to flash TWRP really quickly in the bootloader and install a substratum legacy rescue zip or something through TWRP, thanks for the help.

MI 9 Bricked After trying to change CN rom to Global rom.

Hi Guys, I hope someone of you could help me out.
Recently a Chinese friend of mine gave me an MI 9 as a present. But unfortunately they ROM of the new phone was the CN version.
I found a way to change the ROM by doing the unlock bootloader and flashing TRWP, after that, I downloaded the MI9_Global_V9.5.30_vendor_fw_flash, went back to the Recovery and wiped the "Delvik, cache, SYSTEM and Data. When I was trying to install the rom I got an error telling me the Global rom file was corrupt and restarted the cellphone.
The problem is I am stuck in the Fastboot loop, can't access the recovery and my computer don't recognize the cellphone.
I know I ****ed it up, I was wondering if I can revert that or did I just lost a phone.
Thank you Guys.

Hi,
How did you unlock your bootloader?
It asks for binding Mi account and it's not possible when your phone is bricked.
Yeah, the rule is simple. If it boots into fastboot, it can be recovered. Just flash the global you want with the MI flash tool and the fastboot file.

Guys I am too stupid for this,
I flashed the fastboot global rom in my phone with MI flash but locked it in the end (can't believe I am that retard), now I believed I have bricked it for good.
Now I can't flash the correct fastboot ROM with miflash because I have locked the bootloader while trying to flash the Global ROM. I am at the fastboot loop again.
Can I do something now or I just have a expensive paper holder?
Thank you guys.

flash another official firmware on a locked bootloader BY XIAOMI TOOL V2 https://www.xiaomitool.com/v2
https://www.youtube.com/watch?v=UMkDAxiDdKs&t=10s
Here’s something VERY important before you flash or update the ROM.
1. Xiaomi Phones manufactured for Chinese market are not able to run MIUI Global ROM.
2. Xiaomi Phones manufactured for Global markets are not able to run MIUI China ROM.
We highly recommend you to buy Xiaomi Phones via official or authorized sales channels and double check the system information before flashing or updating.

I think the problem is that he locked the bootloader after install the global ROM.
There are several user that flash global ROM in Xiaomi chinese market phones.

Hi guy,
Same thing happened to me, I felt very stupid, but it was on a MI 8 SE.
According to my experience, only there's a way to solve it and it's booting on EDL mode.
You'll need an authorized Mi account to flash the original ROM.

It should recongnize with no problems.. Just check if you have the ADB drivers and try unlocking the bootloader and then flashing the Rom with the miflash tool. Still, if you have access to fastboot, things should be fine! Don't panic hahha

Read carefully and report
1. Try to hold down the buttons vol down and power, see if : fastboot devices sees it. If so XiaoMi Tool will restore it. If not do the same try recovery vol up + power. Do adb devices and see if anything shows up. Worst case you'll have to open the phone up and connect the EDL pins together and it will flash anything. I use minimal ADB and Fastboot phone plugged via USB cable into the computer and run those commands.
2. Fully bricks their device here is the unbrick factory method
https://c.mi.com/thread-1479882-1-0.html
that's connecting EDL pins with the phone case removed for a phone that doesn't boot at all

Mi9 Global - Accidentally locked bootloader and stock in recovery/fastboot

Hi,
Recently purchased a Mi 9 Global version, got the OTA update to MIUI 11, and everything was well. It is a superb phone, but I like to have root on my phones (mostly for Adblocking and System2, better control overall). I tried to install TWRP (custom version for Mi9) because I wanted to install Magisk/Root or try a different rom eventually. Anyway... I made a huge mistake. After trying to reboot, I noticed things had gone wrong, and was stuck in a boot loop. I guess I panicked and tried to flash the phone back to the latest global MIUI rom (Version 11, Android 10, from official site), using the Xiaomi Flash App but I did not uncheck the "clean and lock bootloader" checkbox on the bottom right of the app, which is somehow enabled by default. The flash failed at that time, for unknown reason, but it seems like it succeeded in locking my bootloader, with an empty partition, except for fastboot access and Mi Recovery module. I have to admit I've always been pretty lucky with all my previous flashes on other devices, and I guess I got a little careless. That was pretty stupid of me, in retrospect.
Since then, I am stuck in either Mi Recovery or Fastboot, and it seems that my originally Global Mi 9 with unlock bootloader has now a locked bootloader. Any attempt at either using the Xiaomi Flash utility gives me an error message ("Erase boot error"), and if I boot into Fastboot and try to flash TWRP, I get the "Remote:Erase is not allowed in Lock State" error.
From what I understand, my options are pretty limited now. The phone is still powered on, stuck in Recovery mode and rebooting every 5 or 10 minutes by itself (probably a way to avoid screen burn-in?), but I can't seem to be able to shut it down in anyway, as there are no fastboot commands to send a shutdown signal. And no matter what button combination I press, the phone always ends up rebooting.
I tried the Xiaomi Unlocker utility, but it needs the phone to be out of recovery to check the credentials binding the phone to my account. All data on the phone has been wiped already, so that's not an option. Two options I have seen :
1. Open the battery cover (required a heat gun and risky), to short some pins and try to flash while there is a short to circumvent the security. I'm not that brave yet, and since the phone is still running and has probably about 80% battery, I don't want to use a heat gun on the device.
2. Shady stuff involving paying 30 or 40 Euros to a random guy who can somehow make everything work magically by remotely logging in on my computer via Teamviewer (Not happening in a million years).
I'm wondering if there is an alternative, other than bringing the device to an official Xiaomi store (I'm in Bangkok and they do have one official shop at Fortune Town), but even then, I don't know if they'll just tell me I got myself an expensive paperweight.
Any help/insight regarding this issue would be much, much appreciated!

Every possible combination on reboot will either bring me to Fastboot or Mi Recovery. I have wiped the data partition, there is no OS on the phone as of now.

Xiaomitool V2 is completely useless. The "My phone is bricked" option is not implemented, and I cannot boot into the OS, unfortunately.
To enter fastboot mode, long press the volume down key and the power key. Then unlock bootloader with Xiaomi app.

From what I understand, the "normal mode" needs the tool to be able to access the OS while it's running. I don't have an OS. I will give it a shot tomorrow (3 AM here, exhausted, and don't want to boot into Windows again!), but my hopes are not so high. Anyway, thanks for the help, much appreciated! Will let you know what happens! Cheers!

Unfortunately, this is not true. I have downloaded an old version of Mi Unlock (2.2.406.5), which is supposed to work with Fastboot mode. The result is "Couldn't unlock --> Please download the latest version". And the latest version needs to access the OS to verify the Mi account credentials. I don't have an OS installed. So this won't work. Thanks for the suggestion though!

I came across this Mi8 thread, not sure if it's possible on the Mi9, but he seems to have been able to flash it through EDL mode, you might ask him the question: https://xiaomi.eu/community/threads/mi-8-bricked-from-nowhere.55723/#post-543605
There's also this Mi9 thread: https://forum.xda-developers.com/Mi-9/how-to/unbrick-mi9-bootloader-locked-destroyed-t3924966

So I tried to unlock via EDL...

...and I thought it had worked but as it turns out, it did not. I found out it did not when I tried to root to which the phone proceeded to tell me it was lock.
Now, when I go into Recovery Mode, the phone does not come up in ADB even when trying to unlock after using the ASUS unlocker tool... Is the ADB bridge fried forever? How do I reinstate it to be able to root? I don't mind wiping, I just want to recover the possibility to root. Any way to do that? God I feel dumb right now...
Edit: I've gotten ADB to recognize the phone in Recovery Mode by installing the exact Manufacturer and Model ADB drivers but the second I get into Fastboot mode, it's like the side USB-C suddenly becomes non-existent, same goes for the bottom one. Feels like a kill.switch from ASUS to me :/
Edit 2: Is there a way to flash while in Recovery? Or in normal OS operations? (sounds like a bad idea but I'm out of ideas as of now)
So neither of the two USB ports in the phone seem to work for you in bootloader mode?

Exactly, the bootloader is also unlocked after using ASUS's tool .apk, I am on 1910.44 WW, I tried different ADB's while in Windows, tried to copy DeviceID, it all works when in normal boot OR in recovery mode but the second I am in fastboot mode, both USB's stop working. As if ASUS locked the access when I mistakenly tried to gain root while the bootloader was locked. Maybe if I could lock it back but that would require me being in fastboot afaik.
Can I lock it back while in recovery? If so, what would be the prompt?
I would be very careful about locking the bootloader at this point. I heard it can cause a brick if the planets aren't aligned correctly.
Jokes aside, does device manager refresh itself when you plug or unplug the phone in fastboot mode? That would indicate it saw something from the phone.

Sadly no, tried 3 different computers, a plethora of cables, different USB ports. It's like the Fastboot killed the function altogether so as of now, I have yet to find a way to get the phone recognized while in fastboot.

Is there an option to apply a full OTA from the stock recovery?

Before anything, thanks for helping, it's greatly appreciated!
So, no sadly, when I get in Recovery Mode my options are:
Reboot system now
Reboot to bootloader
Wipe data/factory reset
Power off
As anyone would, I tried kicking into bootloader from recovery hoping that it would trigger something different to give me fastboot but to no avail, I wiped a couple of times as well, that didn't pan out.
Edit: I feel like my best chance at this point is when ASUS releases a new WW firmware update, that it HOPEFULLY brings Fastboot Mode to it's original value... But according to a thread somewhere on XDA, it does not install a full partitioned recovery so I'm not having my hopes up...
The other thing would be to butcher a USB-C cable and see if I get a response when connected on the orange USB-C but that's also a risk to take. So that doesn't work, that USB-C gets no response whatsoever.
What firmware version are you on? You could try grabbing the stock firmware zip of the firmware you're on now from https://www.asus.com/Phone/ROG-Phone-II/HelpDesk_Download/, and increase the firmware version in the zip name - for example, if you're on the latest .44 build now, change the .44 in the zip name to .45. Then simply push it to the root of your internal storage, and reboot. After boot you should get a message that a system update file has been found, and that you can install it.
I don't know if this will fix your problem, but it should reflash the stock partitions. And yes, it's true that it far from flashes all partitions, but it's worth a try at least.

I did put the stock firmware but I hadn't thought of changing the name to "force" the phone to try and update! Sadly, when it reached 100%, it said install failed and while trying fastboot mode, it still didn't restore ADB but that was brilliant and definitely worth the try. Thanks for your suggestion, here's hoping the next legit firmware will do it!
EDIT: AND YET IT DID WORK!!! That must have fixed it after all... I unplugged, replugged while in bootloader and finally, that USB chime! T-T
Thanks both of you for your suggestions, 3 brains work better than one!

Nice, glad to see it worked! I tried it myself and it also said update failed, but it had flashed, so I think the error message may just be because the firmware version doesn't change.
I'm assuming fastboot works now then? Do keep in mind that you'll need the abl, xbl and xbl_config images from the edl unlock thread to be able to actually unlock the bootloader without using the Asus tool.

Yeah it works, or at least it did long enough for me to be able to root. I haven't tried it since but I would assume that it fixed it, tomorrow I'll most likely do a RAW flash to fix all potential risks as well as try the latest CN firmware. EDL never worked, that's what got me in that situation in the first place... well that and me not paying full attention.

Question REDMI NOTE 10S (Your system has been destroyed+ locked bootloader) error

I have redmi note 10s. I bacame bored of miui because of several bugs. So i decided to mod the device with a nice custom rom. I started the process. Because it is a mtk device, it has complicated flashing process than snapdragon devices. I entered the fastbootD mode and cleared the system by using adb command(which i dont remember). Then i flashed the custom rom. By mistake, I locked the bootloader by typing adb command fastboot oem lock. But now due to complicated case, the device is showing your system has been destroyed and when i try to force reboot it into fastboot, it still give systen destroyed error(means fastboot mode is inaccessible). Can anyone please help me to fix this issue without using edl pins? I am in a great issue
I cant go to service center as my device is out of warranty
in google there is a pc program than can unlock bootloader of mediatek devices, search for it
Bro i cant access the bootloader, so unlocking it doesnt make any difference
I want to restore the bootloader.

Okay so first of all download "mtk client"
Than open the mtk client
It will give you instructions on how to connect your phone, take back of everything except system(super),vendor and userdata. Tap on flash tab there you'll notice a option called unblock bootloader tap on it and your bootloader will be unlocked
Bro Will this restore my bootloader or only unlock it because if it only unlocks then your help wont work.

You need to see the PM I've sent to you. You will find it here.
Start from BROM mode - that is always available. Then you can use mtktool to restore everything. I have an article about it on my blog, but I am not supposed to post it here... find it in my profile, or send me a PM for help.
