Redmi 4 (Santoni) bricked. Please help.

I unlocked my redmi 4 (Santoni) boot loader and flashed pixel experience ROM (https://mega.nz/#F!INZgnAZI!9fuWhfCuazOO5YPBjxGlmA). It was working fine for a few days (Small heating issue was there). Then one day while i was charging the phone the phone turned off and never turn back on. When i try to switch on the mi logo flashes for a split second and then turns off. I tried to get into recovery but couldn't.
I can get into fastboot mode. I tried flashing the phone using Mi flash tool and fastboot rom. But it shows an error "flash tz error". When i tried an old version of mi flash tool i get the "Unspecified error (0x80004005: FAILED (remote: Critical partition flashing is not allowed))
Please Help.....

Have you tried installing TWRP via fastboot?

I had the same exact problem, i put my phone on charge & when i came back to check it was switched off. It wouldn't turn on except the mi logo. I tried to flash through fastboot turns out my bootloader was re-locked for some reason. I had to re-unlock it then proceed on to fash fastboot miui rom. Check if your bootloader is locked or not.

This is a good idea! Probably u first try to install trwp in fastboot mode. If this doesn't work try to unlock bootloader again and then install trwp.
When all these Option doesn't work u still can open the phone and use edl fastboot mode to flash miui again.

Tried unlocking boot loader and was not successful because the phone was bricked. My only option was to use edl test point. Now i installed miui 11. (Aprart from some minor bugs which can be eliminated by reflashing some other roms) Thank you guys. Now my phone is successfully unbricked.

For somebody who is having the same issues,
My phone (Redmi 4_Santoni) was completely bricked. The only thing i can access was fastboot by pressing the volume down + Power button combination. But i could not install twrp or any other recovery because my boot loader was locked. I got it fixed completely with the help of you guys (Thanks again) and i want to share the procedure i went through.
Condition: Completely bricked with only fastboot access, Locked bootloader.
I tried this video (https://www.youtube.com/watch?v=j27x5iJSS40) but failed because i could not access recovery. So my only solution was to use edl test point flashing. I followed this guide https://forum.xda-developers.com/showpost.php?p=74818435&postcount=3. It was very easy to do. But in the device manager (Press Windows key + R and then type devmgmt.msc and press enter) instead of showing "Qualcomm HS-USB QDloader 9008", the device is shown as "Qualcomm HS-USB Diagnostics 900E". The problem was you have to plug in in USB cable while the test points is being connected with a pair of tweezers or a paperclip as shown in the link above.
Make sure you already downloaded the latest mi flash tool from here https://xiaomiflashtool.com/ and download fast boot rom from the official website. (Go to https://en.miui.com/ Click rom downloads. Click flashing guide. Download the fastboot rom from there for your device.) Now flash your device using mi flash tool and voila. your phone is unbricked.
Thank you guys..

cannot enter fastboot mode

Hi, there.
I need help, please .
I cannot enter fastboot mode in realme x2 pro CN ver.
Does anyone have the same thing ?
I tried the following 2 .
Press and hold volume up + power button*
adb reboot fastbootloader
Fastboot screen will be displayed for a moment, but normal reboot will be done immediately.

That's honestly one of the most useless answers I've read here.
To even be able to unlock the bootloader, you HAVE TO enter the fastboot mode and he cannot. So what you'r saying doesn't make any sense. Like at all.
I do have the same btw and I'm running out of ideas, so if anyone actually has something helpful to say I'd be very thankful.
Neither the button combo nor the adb reboot bootloader does work. I can see the fastboot screen for like half a second and then it reboots normally without even touching the device.
Edit: I just found a way to enter fastboot on my realme X2 Pro.
You have to click on "Start in depth test" on the official Realme App, which can be found here: https://c.realme.com/in/post-detail...64863306907648&subForumId=1197159778845982720
I totally forgot the last setp before actually unlocking the bootloader..

No, and before relocking bootloader, if your not "completely stock", you can brick your device.

Thank you for your answer. Is it true that unlocking the bootloader causes problems with the camera and the fingerprint sensor ?

In my case, only problem with FP, camera was ok.

I did install the testing app and i'm still having that issue where i only see the fastboot for a split second before the device reboots itself. What am i doing wrong? I also enabled developer mode - OEM unlock - USB debug.
I've flashed my device before and i've even been able to unbrick my own device after "destroying" boot image, but this is something new and it's coming from Realme and i don't appreciate it!
I'm actually looking to replace my device with something more flash friendly, what would you recommend as a good budget device to De-Googlefy?

Hey guys..I am facing the same issue. I cannot get into Fastboot mode using the key combination or adb method. With the ADB method and the unlock tool the phone reboots with fastboot written with some chinese characters for a split second and then boots up as normal.
Has anyone found any solutions?
I am on the 5th March 2021 security update.

I also suffer from the same problem, When I want to go to Fastboot, a logo comes for 2/3 seconds and then the system is rebooted.

I am also facing the same issue. Any Help?

Same here.

Xiaomi mi 9 "system has been destrtroyed"

Hello, I have a huge problem with my XIAOMI MI9 EXPLORER EDITION The system of my phone is totally destroyed and all what I can do is bring it in the FASTBOOT mode. A friend who know a lot did over TeamViewer some work. He try to FLASH the phone , but the UNLOOK TOOL don't recognize the phone. He told me the only possibility would be open the phone and bringing it like this in the EDL MODE. The phone is like brand new and I would like to search another possibility for fixing it. Right now I am in KUWAIT lo for the Corona Virus. I would welcome each kind of help.

Yeah, the only way to flash MIUI again would be to get the phone into EDL Mode and from what I have tried the only way to do this is by taking the phone apart and bridge the pins. What happens when you hold volume up and power and boot to system?

Turn off your phone.
Press and hold the Power + Volume Down buttons together and immediately connect the device to your PC. You need to time it perfectly.
It will automatically boot into EDL mode.

Try getting into fastboot, and:
Code:
fastboot reboot emergency
If you don't succeed, then the phone itself doesn't have EDL mode.

Yes, I think this phone doesn't have EDL mode.. But, FYI the command is correct, but it still go straight to the OS..
F you Xiaomi, what is your goal to make us to wait 168hour just to unlock the bootloader??? F YOU!!!

If you still have warranty you can get fixed from a Xiaomi service center for free, however if now I'm sure they'd still fix it maybe for a small fee

try:
Code:
fastboot oem edl

All Qualcomm devices have EDL mode, on locked bootloader, you can't boot as easy as pressing any buttons or through ADB/fastboot commands, you need to unlock it firstly, or using the test point method.
In all my previous unlocked Xiaomi devices I have booted to EDL mode by pressing both volume buttons, I didn't try it with this device though.
