HELP CANNOT INSTALL ROM AFTER BOOT-LOOPING PROBLEM(PICS shot included ) !!

Device - MMX canvas a1 Android one
Os- 5.1.1
Problem HIstory:- phn was not getting started to main menu , it just open and shows either just an Android logo loading screen or shows message optimising app (some times 106 someone 40 or someone 86) after optimising it shows message starting apps and then load screen continues to load

(in pic) . when I opened recovery mode it shows screen Android icon with a triangle and exclamation mark in it with message line no command , I presses volume up and power key
To hard rest it from that screen, I did factory hard reset , wiped cache partition , then boot it , still it just stuck on Android logo loading screen , nothing happens , also I tried different boot modes , flash boot , boot +ftrace( I dunno what's that) ,slub debug off(dunno again) . nothing happens it stuck on black screen ..
History :- previously phn was acting weird from many days ,like it gets restarted abruptly any time , some time it's brightness gets stuck to low or high , apps. No work and few days back it's Google account and Google play services automatically disappeared .. And not even letting to sign in Google play store was not opening , so did its reset , from phn menu , now like after 2 days it shuts off , and this happing ..
also phn is not rooted ,
till now to solve the issue I did the following:-
From this thread http://forum.xda-developers.com/crossdevice-dev/android-one-general/rom-t3120737
i flashed twrp 3.0.x version from fastboot after unlocking boot loader
but it shows this error
and phone keep on restarting (had to remove battery )
then i flashed twrp 2.7.x version ,it again shows this error
and phn again keep on restarting
so i flashed the philz recovery from fast boot itself .then i wipe cache ,factory reset is and wipe data
after wiping data it shows this error .
.
then installed the stock rom zip file from ex-sd card
after installation it shows this error
i reboot the system the phn starts in recovery itself after some time loading and remains in recovery
i then dissabled signature verification and zip md5 check but this this rom doesn't get installed.
also
device is not listing in adb devices but listing in fastboot
and phn mtp drivers do not get install on my system or any other system no matter what i do .
after some time it shows message device driver can't be install (i have already installed the S9320AE driver for mmx)
Please help .im so frustrated right now been trying to make the phn working again from 5 days . its my sis phn she will kill me if didn't get it fix in 3-4 days .
p.s i also tried sp tool method but couldn't find the .txt file needed .

anyone please ??

Bro it is booting properly .. just shows message oem unlocked before booting .Also then i insert sim in it the shows message optimizing apps . is it coz of unlocked bootloader ?? this same message "optimizing apps " was coming before when phn was stuck at boot loop logo animation .. i am afraid
and what would be the best and safe method to relock ?
by fastboot command or android one tool-kit or unlock-relock for android one devices ?tool ?

Redmi 6 pro bricked

Guys,
I need help, I was upgraded to Redmi 6 pro for the miui 10, but when I did an update the phone did not start the system and hence I can not find a solution to install a new system. I have tried some methods because I can not separate the OEM to use Miflash.
Help me please !!!

Have you tried to enter fastboot and flash than with miflash?
Another thing you can try is to enter stock recovery and do a wipe.

I already tried to perform a wipe, but it is still in looping, when I try to use Miflash it has a "erase boot error"

Then you need to enter edl mode.
If your Bootloader is locked you have to use the testpoint Methode:
https://forum.xda-developers.com/showpost.php?p=77709470&postcount=3

Testpoint EDL mode also wont work.
Need EDL Flash permission from the Xiaomi, which they wont give..
My device is in bricked state for the last 10 days.
Better visit your nearest Service point ..

i need huge help!!

hello guys. after a update my redmi note 8 pro (global) cannot boot. i can only get on fastboot but i never open my bootloader. i cannot get to recovery mode with vol up + power no matter how hard i try. what can i do? i cannot flash from mitool with locked bootloader i guess cause i get a stupid error.

Unlock the bootloader first.
https://en.miui.com/unlock/

It's pretty easy to fix if you can enter into fastboot mode but in my case situation is very different my device is completely dead/hard brick just notification light blinks, & only the solution is to get the MI Authorized Account & i don't have :crying: if Someone can help me please help

try with EDL mode ..
you can flash without unlock bootloader
it only works if you are actually updating from your own device and not by manual updating because you chose the MIUI ROM file incorrectly

Phone keeps shutting off after update to miui 12

Hi,
Today I tried to flash the new beta Chinese miui 12 rom. I flashed it through my orangefox recovery. But when my phone restarted after completion, it shuts off as soon as the redmi logo comes. I am unable to boot my phone. I can't go past the Redmi logo, it closes the phone right after the logo appears.
I can't go into recovery mode either, but I am able to go into fastboot.
I tried to flash to a previous miui 11 rom but the problem is the MiFlash tool gives me an error saying " failed, device is locked"
I can confirm my device is unlocked so I don't know why its showing this message. My phone is also rooted.
Can someone please help me, I would appreciate it a lot! Thanks.

If it says it's locked than you should unlock your bootloader again. I had it twice. On redmi 3 unlocking bootloader helped but I didn't wipe data before flash. On redmi 6 pro it locked for and only flash with authorized account in edl mode helped. Try to unlock bootloader. Maybe it will help.

So it was wiped before/during update. So the only thing is flash in edl with miflash. Someone with authorized account have to help you.

Please check again if there is unlocked sign when you turn on the phone. If not then you have to unlock again. If your device sakura_india and flashed sakura the chances are you bricked your phone by flashing wrong firmware.

Try go into Mi-recovery on the device, the official recovery, and flash your device official recovery Rom.
Since there's recovery Rom for this device, there should be Mi-recovery on the device. Even if you did not unlock bootloader, flashing official Rom via recovery should work.
Your Windows user name is very long and contain some non-English characters.
Try put your Rom under Windows C:/ drive when you want to use with PC.
You can see in Mi-Flash the file name got cutout.

If you have another device with you, then transfer the sim to the other device.
After that, use the mi unlock tool in your PC. It asks for a login verification code which now is sent to the second device after verification, just follow the steps to unlock the device.
(Sometimes fastboot logo won't show up even if you are in fastboot mode but it doesn't matter)
Next step is to delete the system, data.... with help of a custom recovery
Then flash your rom with MiFlash

yes, when i go unlocked bootloader seem the message for active option unlock in config, but i cannot start the system

By the image you've posted, you did a flash without locking bootloader, but you said you locked the bootloader. Did you try to flash after locking?

I think he means he did not unlock the bootloader. He doesn't mean he relock bootloader.

under fastboot mode, connect to PC and
Code:
fastboot reboot recovery
This should have the device boot into recovery.
Does this one work?
I don't understand what thing don't go properly.

So, to get this situation clear....did u try to flash a custom ROM using fastboot mode or stock ROM using MiFlash tool without an unlocked bootloader?

You have access to Mi-recovery.
So try this:
Download Mi Phone Assistant v4.2 Beta Official
and install it. Then right click it and select "Run as administrator"
Phone boot to Mi-recovery and connect to PC
In Mi-recovery, select the "Connect with MIAssistant"
Then follow the step similar to this thread:
https://forum.xda-developers.com/t/...ocked-bootloader-mi-assistant-whyred.3798165/
Make sure your device showing in the Mi Phone Assistant is matching the Rom you are going to use.
You cannot flash other region Rom into your device.
You can upgrade MIUI version or maybe same version as you had, but downgrade is likely not possible.
If the English version of this Mi Phone Assistant is not working, try the Chinese version here:
https://www.xiaomi.cn/post/26880473
https://miuiqt.cn/311c73
Use Google translate on you other phone or someone else phone to use camera translation.
If there's account problem

The best solution is indeed find official Xiaomi support.
If finding Xiaomi support is difficult to you, then you can try to find EDL support, but there will be scams.
Another thread of your device had some steps that makes Mi-flash work. Maybe also try that.
