Hi there,
I need your help with my device which I just bricked in a peculiar way...
So, something I flashed was not correct. That resulted in an infinite reboot loop (the logo is shown for half a second and it reboots... endlessly). I just used the volume-up rocker to go into fastboot mode to fix the thing as I usually do. I booted into fastboot and this is where it become weird: I cannot do anything!
If I try to use fastboot continue, the phone reboots endlessly again.
If I try to boot to any img (TWRP or signed recovery or signed boot), the device tells me it cannot because it is locked.
If I try to unlock the bootloader (again, because it was), I am told that I am not allowed to do it. The problem is that I cannot boot into a ROM to go into dev mode to allow this.
If I try to flash things, it obviously doesn't work either as the bootloader is considered locked.
The worse here is that since my phone is "not" hard-bricked, I cannot go into qhsusb_bulk mode and use Qualcomm tools to unbrick the thing.
Can I still do something myself or am I screwed?

Still you can do that hard brick recovery method it will work for sure..switch off your phone completely and try to connect qhsusb mode.
I had no idea that I could force the qhsusb mode. It worked indeed. Damn ARM devices with their non-standard way of doing anything...
R3 Pro (3GB/32GB, 2015817 version) came with some chinese/sellers custom ROM (and locked bootloader). It was heavy and bloated, so I decided to update it. Tried latest global stable (fastboot) ROM via miflash, flash was successful but that's was a lie - it stuck on mi logo...
Then I tried various other ROMs, global and developers, latest and older, some xiaomi.eu, manhit, etc. (for locked bootloader) and all I've got was either just a mi logo or mi logo with "powered by android" animation beneth. I left it for hours after flash and still nothing.
Then I found some ways to flash twrp, did that successfully, booted into it, wonder around in terminal and file manager, tried some recovery ROMs - but the result is the same - just logo or logo + animation.
I can get into fastboot (but it doesn't realy matters since bootloader is locked), download (EDL) mode, that Xiaomi menu (with Power and Vol+, with "shortcuts" to all the modes, hardware tests - btw. everything works there, etc.), twrp, charge battery (with some ROMs phone just gets warm and I know it's charging, there are no LED and/or animation, but in some everything works just like it should), but just can't boot into OS.
And I'm going nuts!
Here are some logs from the last ROM (i don't even know anymore which one is it) - pastebin.com/qaKVzxue and pastebin.com/dM3nEVj0
I'm not so experienced in looking at that but seems like every other thing in there, like cpu, i2c (touch/sensor), sound, battery, etc. is broken/faulty which is not true - everything was fine before update, and everything IS still fine according to inbuilt (xiaomi) hardware tests.
So somehow it seems that all the ido ROMs I tried are wrong for this device? Or am I missing something (quite possibly, I'm tired and pissed off)
Last night I did a backup of efs/nvram and then wiped internal memory/partitions, flashed latest global ROM, restored efs/nvram - phone stuck, but this time not on MI logo but freakin' penguin logo (like here en.miui.com/thread-377870-1-1.html). Same logo is for fastboot mode, no more bunny. Then flashed twrp and phone now shows mi logo with "powered by android" animation beneath, like before...
I don't know how this works with Xiaomi phones, but looks like it worked with some factory/seller special combination of ROM and bootloader. Then I did update and something stuck, maybe differences between ROM and bootloader, or some inside/hidden security mechanism that stops boot process? And because I can't find original firmware and/or bootloader is locked (maybe even updated?) it's now stuck...
Either that or some HW fault, but it would be insane that official ROM update with official tools and in factory download mode with full battery can cause such problem!
Can you go to twrp recovery?
Yes, like I said in the first post. I can do anything but boot android/MIUI. It's either because of locked bootloader or somehow official ROM installed officialy (via MiFlash in EDL mode) bricked phone, which is catastrophic bug i.e. epic design/implementation fail by Xiaomi.

Sorry to intrude, I have pretty much the same problem.
Phone is stuck in bootloop and I can only access fastboot mode and EDL mode (but in EDL the phone does not connect to pc) and when I try to flash a stock ROM (since I know it is a software issue due to an unfortunate update) it says "locked device". So I tried to unlock it via MiUnlock... but phone cannot be verified 'cause "account not bound to this device" and obviously I cannot change any options since I cannot use my phone.
Please, help
it was happened to me about 3 days ago when i play around with the twrp & rooting thingy... tried everything from youtube to various forum solutions... just one link really works when you only have fastboot options and your phone bootloader is still unlocked. just follow the steps in the OP... key things here is downloading the tool to read your phone as mentioned in the OP i.e [TOOL]Minimal ADB and Fastboot [1-6-17]
1) Download Tool -> https://forum.xda-developers.com/showthread.php?t=2317790
2) Follow all the steps in the OP -> http://en.miui.com/thread-277276-1-1.html
3) Enjoy your phone from back from the dead.. LOL!
4) Remember here, the key is NEVER GIVE UP and PATIENT!
NOTE : The Device will start, wait till completion , it can take up to 10 Minutes. -> for me around 15-20 minutes for I have flashed the current beta rom of MIUI8 7.6.8
cheers, guys!

I had a similar situation.
Officially unlocked boot loader. Flashed TWRP using fastboot. Only got the mi logo and a boot loop on start up.
Could not turn on. Could not boot into TWRP.
When the phone was boot looping I could still get into fastboot mode by holding power+volume down.
I booted from fastboot mode into TWRP by opening the command prompts and using
"fastboot boot twrp2.img"
That got the phone available from windows explorer. I was able to move a new ROM image to the SD card and install from TWRP.
Currently running lineage 14.1 -20190112.
I lost a bunch of **** but my phone seems to turn on for the moment.
Note, I still cannot boot into TWRP using the phone only. I can only boot in from fast boot as above.
My Device - Redmi Note 3 QC
I was using the MIUI9_MiuiPro_Port_Hydrogen_to_KENZO_Stable_V9.5.1.0_MOD_KISASANYA. Suddenly it restarted and never booted up. It is not dead cause it still booting into recovery, I can flash ROM's but the problem is it never get past the MI starting boot logo(not the booting one which has an android written below the mi logo). The CPU is heating continuously on the logo screen. I don't know what to do at this point. I've tried every method on the forum but nothing helped.
At this point, I think the CPU has died:crying:. Please if anyone can help in any sort of way. Thanks.

Use Format data(not wipe) option in twrp before flashing rom.
Stay on latest firmware too.
As @naik2902 said use format data but do not wipe or flashing lazy flasher might work for you. I suggest flash lazy flasher first it it still does'nt boot up then try formatting.
Hello, I have a xiaomi redmi note 4 mtk phone that got stuck all of a sudden in a bootloop, and I have no idea why or how to fix it, the phone's bootloader is locked, there was no new version installation going on/attemp to update software or anything similar to that, the phone just started to bootloop for no reason, stucks on MI logo for 1-2 minutes, then shuts down and restarts.
The real problem is that Im unable to enter fastboot or recovery mode as both doesn't work, so I can't think if any way to reinstall the system, connect the phone to the pc and somehow fix it or anything like that. Does anyone have any idea I can try? Cause Im pretty much lost...Thanks!
update: I managed to get to fastboot, but my usb debugging is disabled, what should I do?
Hi All,
I am currently in the phone repair business. Well i buy as much as i can fix and sell on. Its all fun. I have a very nice one currently and looking to see if anyone has ideas. All i want to do is boot to recovery that is my current goal.
So phone clearly has corrupt installation, likely a flash Rom or update gone wrong. It boots to Huawei logo then reboots and that's all it does. Tried de-powering and all sorts including removing battery cable but to no luck.
There is no recovery mode
No download mode
Can get to fastboot but unable to run commands it seems due to FRP lock. I am not worried about FRP lock at this time, i only want recovery back.
Tried:-
All flash commands and all fail
Any attempt to get to receovery or download mode fails
All three buttons to force SD card boot fails
Currently trying to boot using SD card but seems i need to change boot devices from within recovery. Well it has no recovery mode so no luck there.
So it is pretty much a brick at this point and could be a write off but before I give up does anyone have any other ideas? maybe a FB command i can run with FRP lock and bootloader lock on?
Thanks
Karl
