Xiaomi MI4C don”t start ! - Xiaomi Mi 4C

Hi guys
I have a big problem with my Xiaomi MI4c , last night i flashed a incomatible room , not works and now my phone is dead. i Cannot boot , i can not use the download mode ,i cannot use the recovery mode, i cannot connect to pc:/
i need help, someone know how to fix it?
Thanks.

If the pc recognizes nothing at all and you can not enter fastboot, I don't know of any options.
However if you're bootlooping and can still enter fastboot, this seems by far the most successful unbrick method so far: http://en.miui.com/thread-237832-1-1.html

[Q] How to unbrick Xiaomi Mi3

Hi guys.
I have for a few weeks one Xiaomi Mi3 16GB Snapdragon (WCDMA). Because I thought it was too slow, I flashed another rom by Mirecovery, but I think I used a wrong one because the phone is completely dead! I am not able to get access to the recovery mode or fastboot. The keys don’t work anymore.
This is the rom I flashed: xiaomi.eu_multi_NX403A_4.7.11_jb-4.2. downloaded on miuiandroid.com.[later I heard this is a rom for zte z5s mini, so really wrong one ]
After installing of MiPhone2.11.6, the first time when I connected the phone with the pc, the red led kept lighting on and the driver wasn't installed, but the phone was recognized by MiFlash(com20, i think): flashing did't work because there wasn't a communication with the port. After that I tried to reinstall MiPhone and afther some attempts, when I connected the phone with the pc, the red led kept lighting on for a few seconds and the driver was installed. But the phone wasn't anymore recognized by Miphone, so again no possibility to flash it.
I’m really desperate because i used the phone just for 2 weeks.
I would really appreciate if somebody would come with a good solution.
Thank you.

if you have no access to recovery or fastboot, the phone is finished
one of the worst things you can do to a device is flash the wrong software, as you see.

[HELP] Bricked Oneplus 6 - Qualcomm CrashDump - already tried everything

Hi everyone!
Well guys, sorry to bring this subject on thread again (because this forum has a lot of guides to solve this problem).
But I'm without hope with my phone at this moment.
Let me tell you guys my sad story...
I have an Oneplus 6 since december 2018, and never, NEVER, tried to use any modification on my phone.
I am from Brazil (so sorry for my bad english =] ), and here we CANNOT use Oneplus Support services (I've tried but only received the response "sorry I cannot help you on your country"), so because of this, I've decided to never apply any modification to avoid problems.
This week after a simple reboot my OP6 started with "Qualcomm CrashDump" error and my despair begins.
I'm not able to enter on Fastboot Mode. When I try, the systems attempt to boot (the fastboot mode logo appears) and fall down into crash again.
I'm not able to enter on Recovery Mode either. This method shows nothing, only black screen and after some time the crash screen comes again.
I do not have Bootloader unlocked too.
Any suggestion to use TWRP via fastboot.exe or ADB are useless, because I cant make the connection. At least I think that is impossible because the 'adb devices' command does not find the device.
I followed a lot of guides from XDA to solve my problem, including the Mega Unbrick Thread.
I already downloaded at least 8 different versions of msmdownloadtool in consecutive attempts of unbrick my phone. Nothing really helps.
The most weird situation is that msmDownlodTool can finish the proccess with success. The driver installation is working... everything seens OK using the tool but my phone does not revive
Someone have a suggestion for me?
Any suggestion, tool or alternative method is welcome in my actual situation.
Sorry if I posted at wrong local, just tell me and I can fix if necessary.
Thanks in advance to all of you guys.

Hi!
Thanks for your reply, but I think you do not read my entire post
As I said, i've already tried at least 8 different versions of msmDownloadTool.
If you have any other suggestion, I'll appreciate.
so you can't boot into fastbootmode anymore?
Had the same problem once before and solved it by flashing the correct twrp by fastboot

Yes, I am unable to enter into Fastboot Mode.
When I try, the logo saying "fastboot" appears, but after 4 seconds, the systems stucks on CrashDump error screen again.
That way my PC cannot find my phone with ADB or FASTBOOT commands.
The only tool that works is msmDownloadTool, but even with a success run with that tool, my system does not start and stills under CrashDump error.
I was thinking if exists some version of msmDownloadTool that justs restore the fastboot and unlock bootloader with brute force.
Thats my last hope

Source is a videotutorial. google oneplus 6 hardbrick and click the video of Max Lee
(it worked for me)
the download takes an awful lot of time
first get your phone into qualcomm download mode by holding down volume up + power button and plug your device in your PC.
(first unzip the hardbrick zip folder) then the oneplus 6 folder and than the .exe file and click 'start' if it detects your phone.
That is flashing every chip and Hydrogen OS 5.whatever.3 but that is not important. Your phone should boot and than you can install Oxygen OS with android 10(thats the other zip folder) using the local upgrade feature.
(make sure to enable google play services after upgrade from hydrogen OS)
Hope it will work for you too if you haven't tried it already.

Need help! No fastboot!

I was on Crdroid and wanted to get back into Miui since there was weekly miui 12 version now. Downloaded it and flashed it but it would not boot. I remembered on poco i had that i needed to flash latest miui andro 9 before flashing latest miui andro 10 for some reason so i got back into twrp and did it. After reboot it went into some sort of boot loot and i lost any recovery and fastboot. Cant get into edl for that matter also. Anyone has any suggestion?
Can you elaborate a bit more, when you try to boot into fastboot with the button combination, does it work?
Do you get any indications when trying to turn on your phone?

Button combination gives me blank screen and revovery gives MI logo and just that until it rebots and stays like that in some loop. I can get into test mode after opening it to try QFill flashing but i forgot about account authorisation thing. I do not have any type of service center in my country that wants to deal with this. Issue is probably due to anti rollback policy in 2s. So i need solution to flash somehow thru qualcomm port but aparently only wth that account that has authorisation.
Thats where i got till now. Spent a whole day also at 4pda trying to find solution but nothing there worked for me

Oh that's unfortunate! I think that in this case you will need to find someone with an authorized account that will flash it for you remotely. There have been some people around here offering that service for a small fee but it might be worth paying as that might be the only way to fix it.
Same thing happend to me, first time i tried using custom rom. i dont know what exactly happened. i think its have something common with anti-rollback feature. I sent the divice to OFFICIAL service center.... I told them "use mi flash tool and authorised account to flash fastboot rom in edl" These OFFICIAL trained technicians... ehm idiots... change whole mother board.... atleast they count it as warrasnty repair.... there is one guy on reddit who succesfull unbricked his device via "shady bussines" (there is also contact on reddit page)... some guys offer xiaomi unbrick services via teamviewer. you can give it a try: https://www.reddit.com/r/Xiaomi/comments/ftix9v/shady_services_unbrick_with_mi_authorised_account/ EDIT: its last reply reddit (hope its allowed to post links)
note: you can put yr device in edl mode by pressing powerbutton. im not sure if its pressing or holding. (yr phone need to by connected to pc, then mi flash detect the phone if all drivers are instaled, it should be shown in "windows device manager" as PORT named "qualcomm hs-usb qdloader 9008")
if you dont have authorised acc. this will happen https://imgur.com/a/oJVpKEl so you need someone with authorised account who will unbrick yr phone via teamviewer [Sorry for my bad english]
Ijust dont understand why xiaomi dont allow user flashing in edl mode... or just make harder to brick phone... i had oneplus and i never bricked it. bricking xiaomi is just super easy thank to their stupid anti-rollback and other b****its. i will never use custom rom on xiaomi again. i will dont buy xiaomi again
Did you try the MI Flash app? ...try to fastboot and check if mi flash works
Also try fastboot(combo-buttons only) and see if you can see the phone (cmd -> fastboot devices) ...if you see a device then you are good to go
If you have a fastboot miui rom you can use my guide: https://forum.xda-developers.com/xiaomi-mi-mix-2s/help/weird-behavior-boot-loop-random-t4086703
It's like using MI flash program but doing it manually - if mi flash gives you issues or else
P.S. CMD MUST be with administrator rights of course!

Xiaomi Redmi 9A totally dead after PS Flash Tool

Hello there,
first of all excuse me if its wrong section to post such things.
My Redmi 9A won't turn on after i've flash it using PS Flash Tool , i've tried to charge it, button combinations and other things...
whenever i am connecting 9A to my PC it says "unrecognised USB device" and i am completely out of clue what can i do to bring it back to life.
any help will be appreciated
Got the same problem too i cant find a solution either, been searching for weeks
Same here after trying to unlock bootloader
Hi ! Same problem for me and I'm looking for a solution. I bricked my phone 2 months ago... there is 1 solution that I found but IMEI is lost (not a big problem, you can flash it) and mobile network connection is lost (this is my problem). So you can flash a custom recovery with SP Flash Tools and flash a custom ROM like Havoc OS through it and that's working excepted the mobile network connection...
I found the solution and fixed my friend's 9a. It seems that after doing stuff in brom mode, the phone gets stuck somehow and all hw buttons wouldn't work at all. What I did is I opened the phone and removed the battery cable and put it back to reset the phone state, then turned the phone on.

Poco X4 GT bootloop, can't access fastboot & recovery

Hi, I accidentally bricked my phone flashing the wrong image.
Now i can't turn off the phone, cant access to recovery or fastboot. (device doesn't respond when i click any button).
'Poco' logo is in loop. Anyone knows a way to install a ROM? Any way to access fastboot in this situation?
Try pressing the buttons for a long time. It resulted for me to get to recovery mode, but no to download mode. Sometimes it works.
I bought a poco x4 gt like that too, hoping to get it fixed, I believe the way to get it is via EDL mode and miFlas, but for now miflash still doesn't recognize the image of the poco x4 gt. I hope that in some future update I will recognize it.
i have same problem
Same problem here
did anyone was able to find a fix? or at least locate the test points for EDL?
mtk devices use a different way to access edl mode. in my case I access the edl mode, the computer recognizes it, the software recognizes it, but when running it says that SPflash still does not work with the scartter version of the rom that I downloaded
how did you manage to boot into edl mode? i tried several hw key combinations but it gives me "preloader handshake failed" or several BROM error.
i think my scatterfile seems ok. its just the brom/edl connection.
when you turn it on with the volume button less pressed and it connects quickly to the pc install the MTK driver and then run the python where it will read the brom
Mine already fixed

what did you do?
if any one want to fix his poco x4 gt bootloop only. can't reach fastboot or recovery. at first you need auth to bypass dim 8100 security. i found a person on github name Rafon he fixed my phone and it's working perfectly right now. his username on telegram is @Rafon24
same issue
the only way of fixing is through an authorized xiaomi account sadly
i however found a way to turn it off when nothing works:
press all 3 buttons (volume up, down and power for like 20 seconds)
and then it will turn off
