Hello guys,
I am facing strange problem on my Mi4. I have connected my Mi4 in fastboot mode trying to check if bootloader is unlocked and I made a typo "fastboot lock" instead of "fastboot unlock" ? and my Mi4 went to black screen with no sign of booting.
I am still able to connect via fastboot and PC shows my Mi4 as Fastboot device and I am able to do commands in fastboot via CMD but I cannot see anything on the screen, it is just black but I can see the white light from back side od screen when I open Mi4 case so it turns on but not showing anything. MiFlash can see my device also as fastboot, no COM drive mounted in MiFlash so I can't flash Fastboot ROM.
When I plug phone to charger, I can see red led light but Mi4 seems to be bootlooped, it restarts all the time.
Any tips what should I do?
you can try Qualcomm HS-USB QDLoader 9008
it is a factory mode it may fix it
but i am not sure
Same problem solved on my mi3w
After "battery change"
Before that
I tried 9008 deep sleep cable (search on YouTube) didnot work
I tried testing points connected didnot work
After one week I buy a new battery and put it in my device
Its worked

Solved: See post below.
So I decided to go back to Kitkat from Lollipop. To do this I went into TWRP and restored a 38R backup I made when I first got the phone in November. TWRP did its thing and booted back into 11S 38R and it seemed to work. What then happened was that I was prompted to update to 44S so I did and the phone rebooted into TWRP. TWRP came up with some sort of screen, I can't remember what it said but the last line said something about an MD5 check not beeing needed. It then turned off and I haven't been able to get it back on. I've tried holding down the power button on its own and after around 5 seconds it vibrates but nothing happens. Also when I plug it into my PC or charger the charging light doesn't turn on.
I've tried to get into recovery and fastboot mode by holding power button+up/down volume but nothing happens on screen but I still get a vibration. However when I press volume button up+power button it seems to be recognised in Windows and it brings up the device as "QHSUSB_BULK" but that is it.
Does anyone know how to fix this?
P.S: I've got a nandroid backup + modem backup from when I first got the phone available if that helps.
I was able to fix the issue using the Oneplus Recovery tool. The issue was that the phone was not being recognised by my PC despite installing the drivers included in the recovery tool. This post in the recovery tool thread had the answers:
"I also deactivate unsigned driver installation but still same fail... I found a Qualcomm HS-USB QDLoader 9008 2.1.0.5 for Windows 7 that I used. I opened the Device Manager, I found my device named QHSUSB_BULK with an yellow triangle. I pressed udate drivers , choose from computer and installed that Qualcomm HS-USB QDLoader 9008 2.1.0.5 I donwloaded. AFTER THAT the tool found my phone and I was manage to flash ROM took me half a day. I cant have done wrong , somethnig must be wrong with the drivers in the tool for w7 64bit or something . this was the first time I have hard bricked a phone EVER and I have flashed a lot . But im glad it worked out with that Qualcomm HS-USB QDLoader 9008 driver since that guy also had same problem as me and later got it to work with that driver. Qualcomm HS-USB Drivers"

So that was how I fixed it.
Why it broke in the first place is a mystery but I'm just glad to be back on Kitkat 44S.
I tried to replace the battery on my Nexus 5.
powered it down and opened it up. actual swap was done without incident​Now the phone does not recognize neithe of my batteries (old and replacement). I can boot it into bootloader just fine by plugging it in a charger, but the screen will show a battery with a ? in it when trying to boot the phone.
When I plug the phone in my PC, it will only get recognized as Forge HS-USB QDLoader 9008 (COM3) under PORTS in Device Manager. I've tried the diag tool here: and all tests look fine.
Rooted, bootloader unlocked, ElementalX kernel, 5.1.1
Thanks for any help!
Hi. My mi5 3/64 variant was functioning great till tomorrow... suddenly i locked the phone and it didn't unlocked....i tried several times to boot up the device. I put it on charge and No Charging LED was showing. No lights. No fastboot mode, No recovery mode, No boot nothing. I am helpless now. Wasted 300$ on this phone 4 months back.Only black screen is what i am watching now. Please help me. Device is not even heating up. If i plug in the device to the pc it says Unrecognized usb device(Unknown Usb Device). I made a EDL cable. Yet it didn't recognize the USB device. What to do now.NB: Bootloader was unlocked and was in official AEX ROM
When the Mi Mix 2S is in fastboot and the Unlock program on the computer says to connect the phone to the computer, when I do the phone screen displays the text Press any key to shutdown.
I've tried different USB type-c cables, different USB ports, tried re-installing the Fastboot drivers and what's worse is fastboot mode stays when the Unlock software is not running. I can plug in the phone to the computer while phone's in fastboot mode and it stays in fastboot mode.
Is the Unlock software supposed to say how long to wait before trying to unlock the bootloader?
Here is the updated bootloader unlock announcement from Xiaomi MIUI forums http://en.miui.com/thread-246705-1-1.html
please read title and help
restore it with msm tool
how to connect the phone screen is black
If the screen is black it may already be in EDL mode. Plug it into a computer and check device manager for something like "Qualcomm HS-USB QDLoader." If that's there, you just need to get the MSM Tool for your model and make sure you have the right drivers.
If you can't get it into EDL mode, you will have to file a warranty claim with OnePlus, no other choice. Mess around with the buttons and see if you can get it to reboot or try the EDL key combo (hold volume up and down and while holding plug in the USB cable that's plugged into the computer). You don't have a chance of repairing it yourself if you can't get into EDL, end of story.
pc recognizing this Qualcomm HS-USB QDLoader in device manager but in msm tool it is showing n/a.and also in device manager it is showing triangle error on device.i am using official driver provided by msm tool poster.
Need some help unbricking (solved)
I bricked my OP9 doing some stuff today. It will not turn on, access bootloader, or anything. When I plug it into my computer, it makes a connecting sound, waits 10 seconds, then disconnect sound, then repeats the process. I tried using MSM...

It's can help you
Well you're not the only one I guess. That happened to me as well. So perhaps, Alhamdulillah I can help you out
The screen still remains black that means your phone is in the EDL and you'll need to get it out of it and then get back to EDL again to use msm.
Anyway, hold the power + volume up + down all simultaneously for a while. It'll take you to the Fastboot mode. Don't worry, it definitely will take you to the Fastboot mode.
Then you can do the rest of the flashing as you wish
