What is 'qhsusb_dolad' ?It is the situation when you can't boot into your phone,recovery mode and any other visible interface. When you connected your phone to the PC, the LED will flash and your PC will show that they were searching for the drivers needed(win7/8) but they couldn't find .......If it is commom for you to remove the battery when the phone did not shutdown completely or when you ran into 'No-Response' , as time goes by ,it will be inevitable that you come across the 'QHSUSB_DLOAD' situation .
But from now on ,you needn't worry about that for I have found a way out.
Tools needed:
Hardware: A PC running XP and higher (win7/8 recommended) and your usb cable
Software : MIflash and MIAssistent and a certain mi update rom(It is a *.exe file---fastboot file)
Steps :
1. Install the first two softwares described above(Run as administrator) in your PC (You need to disable the enforcement of digital signature while on win8 in the advanced startup (press 7 or F7)
2.Boot into fastboot mode(you just need to do with your two buttons and usually you cann't see the interface for your screen just won't show in this situation) before connecting to PC
3.Connect you MI2/S to your PC via the usb cable and the pc will recongnise it in the device manager panel(if not, update its driver in the unknown device---qhsusb_dload)
4.Open the miflash and click fresh to load your phone's serial number
5.Flash the update rom(the self-extracted-to folder) into your phone and reboot .

Explanations:
Miassistant contains the 'qhsusb_dload' driver for any phone and it enables the PC(Miflash) to recongnise your CPU serial which is the key part of updating by wire.

Tips:

Try this with your other phone, I believe it will work ,too.

Good luck ,guys !

Hey, guy.
When you want to repair your bricked M2, you need to get the two test points and the battery holder negative to be short-circuit. It will force the low Level system work.
See the picture.

Are you sure you can not boot your phone to fast boot mode? Press key"volume -" and power button at the same time.

When you connect your phone to your computer via usb port, can you find something called"unknown"on the Device Manager panel?

It's easy to save your dead phone with MiFlash. But I have to translate the Chinese guide to English...My god...

I suggest: First of all, connect your phone to your computer, and if the computer find new hardware"QHSUSB_DLOAD", install the driver, then open the MiFlash, and see whether there is device list on the panel, see the picture. If it is, you can flash it and save it.
If not, you should do the "short-circuit" ...

I can not go into fastboot mode but after a short circuit if I try to attach the power cable, the LED turns red when I try to use combinations of keys.
Since installing the battery nothing happens. I have the driver for MiFlash, but i can't find nothing in MiFlash

If the LED turns red,it just says that your phone can be saved(no hardware damage). I had ever met this and I successfully made it. Do what I wrote above and you can defenitely save your phone, not just Mi2/s

The ultimate save method was originally posted in MIUI form:
http://www.miui.com/thread-1130259-1-1.html
http://www.miui.com/thread-1207329-1-1.html

I suggest you try the method below:
1, Take your battery out, find metal wire and make a short circuit between two test point and the negative pole point, see below(be careful, do not connect the wrong point!!!):

2, Connect your phone to computer via usb port(you may ask someone else to help you), open the device manager, see whether a new hardware“QHSUSB_DLOAD” was found, see the picture:

1.png


3, If it is, install the driver attached: Qhsusb Dload Driver
After install the driver, you will find the device below:

4, Remove the metal wire, and install your battery back.

5, Open your MiFlash, you will find a Qualcomm device in the list:

6, Flash a complete rom,such as :QDT10, or JLB15, etc. Your phone will reburn...

If you have found qualcomm device, you could to try use miflash, if device busy, so you need to restart your PC, before Windows starting press F8 and choose "do not check signatant of drivers"

fodev, I have used F8, but the problem remains the same. After clicking flash drive is lost and is only one USB port without being recognized. I try to indicate the correct drive to reinstall win7 but says the best drive is already installed and there. I appreciate any kind of help, please. Thank you.
