Microsoft's official Windows Phone recovery tool has been updated, but the win10 mobile phone preview version of the downgrade wp8.1 brick problem has not been completely resolved. Let's take a look at the win10 mobile phone preview version downgrade wp8.1 brick brush recovery tutorial, I hope to help everyone!
The previous Microsoft official Windows Phone recovery tool recovery equipment may face horror "change bricks" The problem can't be brushed back normally, and the connected computer is recognized as QHSUSB_DLOAD driver.
Although a lot of writing, but the key code is only three lines, many details need to pay attention to everyone, pay attention to the whole process of cmd do not close, are continued to paste the operation below.
My mobile phone: Lumia520T
Computer system: Windows 8.1 64-bit (it is recommended to operate in this system environment, because the tutorials are all in this system)
• First of all, to put this Download the installed software, the driver is downloaded and installed, click here to download. (Only put MPRG_HEX.zip and X2_FlashDriver_Emergency_XP two files, other believe that can be downgraded into bricks know how to download)
to download the software: MPRG_HEX.zip, X2_FlashDriver_Emergency_XP
driver installation: EmergencyDownload.inf right Click ——Install —— OK. (Many people can't install this driver, the solution is to download a Nokia Care Suite software, click here to download) Windows Phone recovery tool, click here to download. (This is the culprit software that causes your mobile phone to become bricks, and remember not to choose the installation path when installing)
Download the firmware package of the corresponding mobile phone, download the firmware package folder directly to the root directory of the C drive.
Pre-preparation steps: Create a new dump folder in the C drive
and then start flashing:
Open cmd, step: start (win) —— run (above the shutdown button) —&mdash Enter cmd——OK
and then jump out of this interface
Copy and paste and hit enter this line of code cd "C:Program Files (x86)Microsoft Care SuiteWindows Phone Recovery Tool"
Copy and paste code thor2 -mode ffureader -ffufile "C:rm-913RM913_3056.40000.1349.2004_RETAIL_apac_prc_213_04_356607_prd_signed.ffu"-dump_gpt -filedir C:dump
The blue part of this is the firmware package you downloaded The name of the .ffu file, replace the file name with this code, and don't forget to change the rm-913 to the model of your phone.
Remember this RKH code, the rest don't care.
After completing this step, you will find two files GPT0.bin and GPT1.bin appear in the dump folder created by the C drive. Find the RKH code with your MPRG_HEX.zip file. The same .hex format file, then rename the GPT0.bin file, name it RKH code, and then copy the two long-named .hex and .bin files to the file where the C drive Windows Phone Recovery Tool is located. Directory, as shown in
Continue to copy and paste and run the code thor2 -mode emergency -hexfile
A74593CEE9F88EDA6D4950CA46A3A634381F9458.hex -mbnfile
A74593CEE9F88EDA6D4950CA46A3A634381F9458.bin -orig_gpt
Note these two very long RKH codes That is the name of the two .hex and .bin files you just copied, don't forget to replace them.
There may be problems here. I have to try several times. I also encountered it. My solution is to re-run the above three pieces of code several times. If it doesn't work, restart the computer, and the miracle will appear. It’s red screen. Today, the small partner Lumia520 brush in the bar also encountered an error code. The solution was to connect a computer with a data cable, and then succeeded. A red screen brush appeared.
The error code encountered during the period is:
85021 85030 error, I understand that there is a problem with the driver or bin hex file
85034
This error code is the closest to my success
84000 this is The computer can't find your phone, the driver problem.
The sign of success is that the command line scrolls a lot. There are probably more than 3 screens.
At the end of the mobile phone red screen, this tutorial is over, and then directly use the Windows Phone recovery tool software to connect to the mobile phone brush machine, after all, Microsoft has updated, fixed the brick problem.
