Help me please! My phone was bricked.

Hi,
My Mi4 was bootloop on logo MI. It was just always going to the MI logo and would keep restarting after 3s-4s. I tried to get it into fastboot then flashed roms like:

cancro_global_images_V8.1.6.0.MXDMIDI_20161230.0000.00_6.0_global
It show me "operation completed successfully" but it still bootloop when it restart. I cant get in recovery mode.
Lastest rom i used: AospExtended-v4.6-cancro-20171101-0156-OFFICIAL.zip
Lastest rom i flashed then my phone was brick: miui_MI3MI4GlobalEdit_V8.2.1.0.MXDMIDL_6.0

Thanks for your attention.
Try to flash ROM via fastboot
With miflash
Yes I think you need to flash your phone with OTHER MiFlash.
Sometimes I got failed/unsuccessfully flashing with MiFlash, but revivify successfully with MiFlash Beta...

Fastboot loop

Hi, i had unlocked my bootloader and made twrp/eea rom on it. Now i wiped via twrp and got stuck in fastbootloop.
while using fastboot flash recovery twrp, it doesnt go to twrp.
trying to use xiaomi flashtool it says updating crc list failed.
please help!
1.You have wiped system and rebooted without flashing any ROM.
2.Have you tried to flash latest fastboot ROM with Mi Flash?
3.You can try xiaomitool v2 also.

Are you using latest miflash?
Does your computer recognize your device in fastboot?
Have you tried to install TWRP again?
Problem solved after i downloaded fastboot rom from another link and flashed it.

twrps not installing

is there any reason why flashing twrps via ADB would send z5 pro gt into boot loop into bootloader unable to access the custom recovry or phone needing to do emergency flashing via qfil to stock firmware i did previously use trwps on device to flash files and to sign boot to always boot twrps recovery when trying to access recovery mode . (before bootlooping)
affter bootlooping and fixing via qfil i have been unable to successful install trwps if i do it bootloop to bootloader.
whats the difference between "meta" / "flat" options in qfil
tried locked and unlocked bootloader on both 10.5.304 and 11.1.021 also tried to go straight to recovery mode affter twrps flashing on both firmware same thing lead me bootloop needing to qfill to 10.5.30
another question can i qfil flash to 11.1.021 straight away without having having to qfil 10.5.30 then ota updating to 11.1.021..
thanks in advance

if you want OTA(over the air) updates you need to lock bootloader. otherwise the updater will say something like phone has been rooted and they cant provide you an update

http://anago.2ch.sc/test/read.cgi/sm...ne/1577014188/ theres a lot of information on this link here are some highlights for me
_____________________________________
>> Crash dump loop of 113 ROM burnt Z5PROGT can be restored by burning CNROM for the time being,
Even if I tried it again, it was useless, so if I look at the syntax at the time of batch execution, it seems that vbmeta.img is not burned.
It says unrecognised option `--disable-verification '.
This time, the boot loader loop only started, and TWRP couldn't start.
This time it may be packed
__________________________________________
>> 117
I'm sorry I want to confirm.
Where did you use the fastboot command?
①fastboot --disable-verification flash vbmeta vbmeta.img
②fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
It is ① that I instructed, but it looks like there are two kinds when I check it on the net.
He seemed to have hit it without knowing it.
Excuse me, can you hit both again?
________________________________________

>> I burned 113 ZUI11 version Gro ROM.
I re-added TWRP, but when I started it, it was usable normally, so I could add Magisk,
After that, it only seems to be unavoidable that it only starts up in normal recovery mode.
It is troublesome to do it every time you want to use TWRP, but it can't be helped.

Stuck in fastboot :(

Hello everyone!
As the title states, my Xiaomi mi 9 is stuck in fastboot mode, after i tried installing the latest unofficial port of Lineageos 17.1 for the Mi 9.
I can not exactly remember how it happened but i guess i must have wiped the phone after installing the custom rom. Silly me...
I tried the following things to try to unbrick my phone:
1. Using the Mi Flash Tool in order to flash the official Xiaomi firmware onto my device. I flashed these versions: 11.05 global fastboot, 11.08 EEA fastboot, 11.06 global fastboot. None of them worked. My phone would show up on the flash tool and the flashing itself was always marked as successfull but sadly my phone would not boot into MIUI and just stay frozen in fastboot mode. Restarting the device did not help.
2. Flashing twrp and trying to boot into it. Sadly, this also did not work out for me. Every time after i would successfully flash the .img file and reboot my device, the damn fastboot screen appeared.
So is there anything i can do? No matter what i try, my device goes into fastboot mode. I tried searching for the answer myself but those who had the similar issue did either not receive any useful answers or the Mi Flash Tool magically worked for them after a few attempts.
Thank you in advance!
Hello,
As long as you have access to fastboot mode, am sure you can recover your device.
You need to download the official ROM that corresponds to your specific devices. If it is global version, download the global version.
Also, before flashing, make sure you unlock the bootloader.

fastboot --cmdline "lge.kcal=0|0|0|x" boot twrp.img
this temporarily boots you into TWRP so you can reflash TWRP again. with this method the TWRP will be deleted once you reboot si you need to reflash TWRP in TWRP. then dont reboot, flash a Good working rom.
Similar problem here.
The line fastboot --cmdline "lge.kcal=0|0|0|x" boot twrp.img
brings up
FAILED (remote: 'Failed to load/authenticate boot image: Load Error')
