Hello everyone ... I have a xiaomi mi5 in bootloop.
- Initial ROM fake seller (learned later)
- I tried to update with MiPcSuite and is now in bootloop.
- I DO NOT unlocked bootloader
- I did NOT access Xiaomi account on mi5 (so I can not unlock it now even if I have permission from Xiomi)
- First of all, I activated the "developer mode" and "USB debugging".
- I can only enter Fastboot mode
-I Can not use the recovery mode
- I can not get into EDL in any way: no adb, no tool here (with the tool says restarting EDL success but restarts and reappears MIUI logo, does not turn on the red light and nothing appears in the device manager)
Thank you
Try to wipe system and install
1. Go to fast boot.
2. Wipe all partitions
Code:
> fastboot erase boot
> fastboot erase recovery
> fastboot erase system -w
flash fresh fastboot image from Mi
Code:
>fastboot flash system <image name>
It works? It has already been tested? I could not find any other guide that told you to do this ... I will not say that I do not trust this, but I want to do other s-h-i-t! I remember that I have the bootloader locked, and I can not go to EDL mode ... thank's
Not sure you are allowed to run the flash command when you're on locked bootloader. I'd try it without erasing, since flashing overwrites the partition in question anyway.
I have experience like you... Get bootloop.
But when I wipe/erase all of internal memory through Mi PCSuite China version, it's boot normally and MiUI8 started.
I tried the same method to apply the official china stable rom on my friend Mi5, it's bootloop... Then when I wipe all, it's boot normally.
Hope this will help you...

You can get help from Google translate app.
Take photo from Google Translate then translate to your language.
Use the Chinese mi pcsuite if the English one doesn't recognize the phone. I am not sure if you cannot enter in any form of recovery you have luck with that though.
Fastboot and miflash that was suggested will not work with locked bootloader.
Your best and last bet is to use EDL mode. The issue with Mi5 is that it doesn't go easily in EDL mode. not with key combo at least. Have you tried this? https://forum.xda-developers.com/an.../guide-how-to-reboot-to-edl-fastboot-t3394292. Otherwise, check for deep flash cable or make one yourself.
in lineage's Usermanual it says after a few steps:
Hold Volume Up and Power buttons simultaneously. Continue to hold both buttons until the “MI” logo appears on the screen, then release.
I get only fastboot-image nothing else.
i did the following comands:
> fastboot erase boot
> fastboot erase recovery
> fastboot erase system -w
>fastboot flash recovery recovery twrp-3.1.1-0-gemini.img
Both Power and + or Power and - : Same result: Fastboot.
I had unlocked the phone and usb-debugging was enabled.
I do use Linux by the way
Hey, did you solve it? I have same problem and I'm desperate
No I didn't solve the problem. I realized that I completely was wrong. I had an Xiaomi Mi 5c in stead of Xiaomi Mi 5.
I finally was able to flash it because I choses the wrong Recovery and Rom.
Then I sold it and bought a Xiaomi Mi 5 which I wanted because it is supported by lineageos...

Hahahah what a story man, I fear I didn't choose the wrong Rom and I have a good brick :') Lineageos is just amazing, have fun!
.....And anyway, in the end I had solved it with a home-made EDL cable 3 years ago ???...and my Mi5 is still alive in my hands 3 years after ?
I had forgotten this thread
I hope you can now sleep well again at night now that you know that everything went well ?
Goodbye
The situation is that I just bought the K20 Pro. Then i unlock and flash by miflash with Global Rom via this thread then the device has bricked and has the message "This MIUI version can't be installed on this device".
Tried boot into recovery but the TWRP has gone and the bootloader has been locked.
Flash back to China Rom by miflash is doesn't work either, help me please, i don't know what to do now, i tried every thing i can.

Miflash only works on an unlocked bootloader. It appears that you have a Chinese Model and you just did what was supposed to be avoided. You should get accustomed to Miflash moving forward. Never use Flash_All_Lock while cross flashing China/Global roms. You'll have to wait to unlock your Bootloader now and post that flash the China rom to get back. If any time you wish to move to the India rom, either use a twrp recovery or just use Flash_All while using the fastboot image which should eventually avoid locking the bootloader

1. if you can still enter fastboot mode, there is a possibility that you can do TWRP flashing again (the TWRP version must be correct so that the data on the cellphone can be read properly) / Flashing from the PC (if you are lucky, the flashing will work properly without any problem or you can bypass the bootloader locked using software or something else). [make sure ROM version must be appropriate because this is very crucial]
2. You can try using the test point method (EDL / Emergency Download Mode) [This method is usually used if your K20Pro is constrained by Hardbrick due to ARB4] , but this method requires you to open the case / body behind your K20Pro. and I cannot guarantee that the flashing process will succeed easily because in some cases if the K20Pro is detected damage / error due to ARB4, then you are required to have an Authorized Mi Account. I might be able to help you remotely, if you agree with the risks & requirements in the flashing process (I can lend my account, but it's not free).
Hi All, I did the same thing - whoever build the UI for MiFlash should be shot - why default that selection to something that will be undesirable!!?
Anyway, i tried to flash indian rom and forgot to set to Clean All, it locked the bootloader.
So i now have redmi recovery and Fastboot options only on phone.
Have tried fastboot + miflash but all options (now with Chinese rom) - says Erase Boot Error.
Tried MiAssistant + Mi PC Suite - it is not detecting the phone in either MiAssistant recovery mode nor Fastboot mode. what is weird is the phone and connector animation on phone is correctly depicting when it is plugged in/unplugged. But the PC suite isnt detecting the device.
Soft bricked - *sigh.... any help will be greatly appreciated from the community
BTW i am more worried that the phone will run out of battery and never wake up once battery drains completely as it is in bootloop into Redmi recovery and can't be turned off (someone tell me how!?) - I don't see the phone respond to charging in any state... : (
Can you still reach fastboot? If so you can unlock phone again and flash TWRP using ADB. After that boot straight into TWRP and connect it to your computer, internal SD storage should then automatically mount. Drag and drop ROM .zip into internal storage, use TWRP file manager to move it out of the data folder and do a default wipe using TWRP. Then flash .zip ROM (for example xiaomi.eu stable) and you should be back in business. Please let me know if you need any files like working recovery image and further instructions.
I had some trouble with my TWRP recovery yesterday, flashed it on unlocked bootloader with Chinese stable ROM installed, on reboot out of fastboot it boots straight into ROM and overwrites the TWRP recovery with default recovery. I fixed it by flashing recovery again, boot straight into it and flash xiaomi.eu stable, now recovery is TWRP and does not get overwritten.

You're probably going to have to open up the phone and pay $20 for someone to use their authorised account to flash an official ROM whilst remoting in to your PC.

Some great ideas - Just tried to unlock bootloader - This device came pre-unlocked so the device is tied to the seller's account.
I have unlock permission - but unlocker say device is not bound to my account matching my assumptions - anyone know what's the best way to re-claim ownership? Especially when I can't get into ROM at all?

My comment was meant for OP but I hoped it would help you as well! I am personally not well informed about the Xiaomi / Redmi ownership situation when the seller unlocked the phone.. maybe you can contact them and get a corresponding password to the account, it has been the solution I have seen offered here. Maybe the emergency flash solution from Robbo.5000 works?
I just got this phone a week now and was only able to unlock and flash yesterday, I was aware of the ownership problem thanks to this forum so I bought the sealed CN version. Hope you figure it out!
Thanks guys. I am going for the Test Point solution - have made contact with the Russian tech the others did and made an appointment. I just have to pretend to be Jerry Rig before then and open her up! Fingers crossed!

You need yo flash magisk after you flash twrp if you want to run regular miui, to prevent it from overwriting the recovery. Its the same on poco and all xiaomi phones

Did you flash the global rom on an existing running Chinese rom or on an empty device (formatted)? Just for myself cuz I'm not sure whether to unlock and then unable to relock. Thanks.

Could you please point me to the person you have contacted?
I'm in EDL for about two weeks now, unable to solve it by different means (seller sais 'send it back', which I'm not goong to do; S-unlock has the service unavailable, even though I've paid them and the guy I contacted there tried through TW to no avail, waiting for a 'money back' now)..
Yeah, I'm not feeling very smart right now.
Short story:
Accidentally wiped OS in TWRP, now only seem to have access to fastboot. Can I fix this? Flash another ROM? Anything? Bootloader is unlocked, can't seem to get into TWRP anymore. Power + Volume up only takes me to fastboot again.
Long story:
Magisk module caused a bootloop. Wanting to try and avoid a factory reset, I tried sideloading Magisk for TWRP which didn't work, ultimately gave up and wanted to perform a factory reset via TWRP, but I've been working late and ticked the wrong box without thinking. Bad idea, I know. Wiped system, yes.
Aside from feeling exceptionally stupid, can this situation be salvaged? The phone doesn't switch off, it just sits in fastboot. I have Minimal ADB and Fastboot on my PC. Any help will be greatly appreciated, really.
Just in case anyone else ends up with a similar problem, the resolution was fortunately rather straightforward - I needed to grab the Mi Flash tool (as it turns out, this version worked best), stock firmware for my version, go into fastboot (which was no issue as that was the only thing my phone would do) and then open the Mi Flash tool and flashing the firmware was pretty straightforward from there. I even managed to get a BSOD during the process, but it's not like it could get any worse, anyway. Rebooted, restarted the process and about 10-15 minutes later, my phone was happily booting again.

With Fastboot mode and Mi flash as fail safes , we can flash to our hears content with no worries !
Also a more automated tool is a custom mi flash tool by a developer called XiaimiToolV2 ,which has a dedicated mode for bricked phones or downloads the latest fastboot roms for you.

I had excaxtly that witha my mi5 , completely dead .
Leave it on the charger for a little bit,mine after an unsuccessful flash with mi flash (catastrophic error message) it turned back on.
IF not download XiaomiTool V2 and try the option for bricked phones.
I tried that yesterday but that option is still in development. Only the modifications one is supported currently. As for the issue mentioned, maybe it's really just a matter of charging the phone first. Can't hurt either way.

Try to use the EDL mode
How to force it to EDL by key combination or maybe deep flash cable ?
My Mi account is authorized for EDL flash but I cant get Mi9 into EDL mode on my PC ( Windows10 )
No OS, but working TWRP
Hi,
I have a similar problem with my mi 9.
I followed a really bad description for the update xiaomi.eu from MIUI10 to MIUI11.
https://www.chinahandys.net/xiaomi-eu-rom-update/
It recomended to wipe alvik / Art Cache, Cache AND System :crying:
So I do not have no OS any more. However, TRWP is still working.
I have a Backup but it did not work :crying:
Is there a better option than the Mi Flash tool?
Please help me!
Since you already have TWRP, download the latest Xiaomi.eu custom ROM available for the Mi 9, which is 9.11.7 to your computer.
Also download the latest TWRP by Mauronofrio from XDA which is 3.3.1-42.
Then use adb to transfer both the ROM and TWRP to your Mi 9.
In TWRP, install TWRP first and manually reboot to twrp using the vol up + power button.
In TWRP, install the ROM, do a factory reset, then finally reboot.

Thank you very much for your reply.
When I tried to make my TWRP backup work I had several problems.
First was "vendor read only". So I went in TWRP to "mount" and unticked the "mount vendor partition read-only" (sounds easy, took me some time to find out)
Then I was able to do the restore without error message. However just boot loop and only the possibility to access TWRP.
After some while I realized that this restored the wiped system partition.
So I flashed the aktual MIUI 11 9.11.7 again and rebooted.
And it worked perfectly! :victory:
I did no Factory reset all the time, it seems that everything is perfect!
No lags, no problems with the camera, no issues with auto rotation.

Hello, after unsuccessful OTA update my phone doesnt boot into Android any more.
I had an original, untouched xiaomi system (not a custom one, not rooted etc).
Bootloader locked like default.
I think update.zip could be faulty - I have no idea how.
I am able to run Fastboot but due locked BL I cannot do much there.
I deasemble phone, pull out the battery, connected EDL pinouts with a wire, and all this togetcher connecter to PC.
Phone is visible by PC.
Downloaded ROM, and tried to flash via MI Flash..
On last moment I am getting error with information that my mi.com account is not athourised to do such a thing.
I tried also Mi Flash Pro founded on Cyanogenmod forum, but without luck - still getting same error.
Does anyone know how to get out from this situation or should I rather open warranty process in Gearbest?

Just flash a custom recovery, the device even had the offical twrp. So?? Just not into fastboot and then flash the recovery by the -- command
fastboot flash recovery recovery.img
(You have to rename the twrp file to recovery or whatever, just write the image file name instead of recovery in the second one. Ex fastboot flash recovery 123.img)
Then command
Fastboot reboot
(Hold the power up button for booting into twrp before hitting enter)
Download a miui recovery rom for your device from anywhere, I don't know I'm lazy.
And before flashing, go into mount select vendor and system if not selected.
And then select wipe
Advanced wipe
Select vendor system data cache.
Swipe to clean
Move the rom to your device
(If your device does not show up in your pc, then go into mount (twrp) select enable MTP if it's disabled, if it shows disabled then enable it again)
After that just flash your rom and then a permissive patch you can ask anyone. Or just flash pitchblack recovery. Fixed my problem of not not booting.
Sorry for the wrong format, wrote it on mobile, as I am a lazy bum.
Wut bruh.
Something similar happened to my friend's Poco F1. It was locked and I only could boot into fastbook, looked everywhere for a solution and found this lifesaving tool . It may work for Redmi 8 too.

thanks so much, that helped
Yesterday I unlocked my phone with the official Xiaomi unlock tool, Then it wiped everything, after setting my phone up, I flashed TWRP (not for my device but for redmi k20, I thought 9T and K20 is the same) and now I'm stuck on fastboot, I tried power button + volume buttons but still stuck on fastboot, I tried adb but still stuck, I tried Reiboot for Android but still stuck. So I used XiaoMiTool V2 (unofficial) and selected 'my device is bricked' then it asked me to select what device am I using, I selected k20 bc I thought it's the same with redmi power, after downloading a rom for an hour, it tries to install but fails because it detects that it's not k20, so I closed it and rebooted my device, now my device only shows the charging battery icon, can't boot into fastboot, can't boot into anything, PC can't detect my phone including adb. Please help me (for free), I really need your help. Thanks!
Your mistake was booting a wrong twrp and then a wrong fastboot rom. You could have saved your device when it was in fastboot mod by flashing an official fastboot rom for your device. But now your device seems hopeless. I think you have no option but to send it to a service center.
In this Case, buy only from Trusted Places! Or Learn how to Flash properly.
If the bootloader is unlocked...
Flash vbmeta.img
Then flash the suitable recovery for 9 power... It might boot to recovery then
