"Backup" to fix your Lumia dead bricks without jtag? Absolutely OK!

Believe it or not, I fixed it anyway. How many people need a tutorial? A lot of words to write (hello, hello, I want to play lol), less people on Weibo m me.
Explain, what is dead brick: boot black screen, can not display the Nokia words, and, press and hold the volume down with the power button, no vibration, unable to enter the brush machine mode, and, the phone plug on the USB cable, computer display qhsusb_dload.

Write in front of the words:
This tutorial is only for dead bricks, however I cannot guarantee 100% salvation, though my own 620 have successfully saved,
The most important thing is: I do not guarantee that after using this tutorial will have any impact on your machine, if you are going to the tutorial and then machine problems, I do not assume any risk and responsibility.

First, confirm that your machine model is in the following list, if not, please give up directly:
RM-820
RM-821
RM-822
RM-824
RM-825
RM-826
RM-846
RM-860
RM-867
RM-875
RM-876
RM-877
RM-885
RM-887
RM-892
RM-893
RM-910
RM-913
RM-914
RM-915
RM-917
RM-941
RM-942
RM-955
RM-994
RM-995
RM-996
RM-997
RM-998

Before saving bricks, you need to do the following 4 parts:
1. Download and install wprt:http://go.microsoft.com/fwlink/?linkid=525569
2. Download ROM, before you use WPRT fallback 8.1 will first download ROM, you can find the downloaded ROM, do not know how to find, you can search your C disk search. Ffu this file, and then you can find the corresponding folder
3. Install the driver: http://server1.infinity-best.c ... P.rar Drive Installation: Right-click the INF file, and then tap Install (of course, you install NCS is the same, that is, installed NCS will not have to install the driver, installed the driver will not install NCS)
4. Download hex file Compression package (Mprg_hex.zip or alternate_hex.zip, because I do not have so many machine tests, if you do not find your hex in Mprg_hex.zip or did not successfully reach the red screen, then, please in the Alternate_ Hex.zip inside to find hex test)

Okay, we're officially starting.
1. First open the command line in Administrator mode, and then navigate to your WPRT directory, my directory in: C:\Program Files (x86) \microsoft Care Suite\windows Phone Recovery tool\
Then the command is typed:
CD "C:\Program Files (x86) \microsoft Care Suite\windows Phone Recovery tool\"
Thor2-mode ffureader-ffufile "C:\rm-914\XXX.ffu"-dump_gpt-filedir C:\dump
Where C:\rm-914\XXX.ffu is the path to your Ffu file, C:\dump is the path to the file you want to dump

Dump out the file into 2 parts, Gpt1.bin and Gpt0.bin. One of the things we need to use is gpt0.bin, and gpt1.bin just ignore it.
2. Change the Gpt0.bin file name to Msimage.mbn
3. After the dump file, do not close the window, note the RKh of the string of things, and then from the hex file compression package to find the corresponding hex file, For example, my string is F771E62AF89994064F77CD3BC16829503BDF9A3D506D3FACECAEF3F808C868FD, Then my hex file should be F771e62af89994064f77cd3bc16829503bdf9a3d.hex, which is the same file name prefix part
4. Change your f771e62af89994064f77cd3bc16829503bdf9a3d.hex to Hex.hex

5. Well, now that you have 2 of the most important files Hex.hex and MSIMAGE.MBN, then connect your phone to your computer and click the command:
Thor2-mode emergency-hexfile Hex.hex-mbnfile msimage.mbn-orig_gpt
Reconnect the data cable, you will see the big Nokia words, this shows that has entered the Red screen mode, you can in the Red screen mode to brush the machine.
(It is recommended to flush the power and brush ROM)

Enter the brush machine section below:
Find the folder where you downloaded the ROM, note that the ROM folder has many files, not just one ffu file
Thor2.exe-mode vpl-maxtransfersizekb 1-vplfile "C:\PROGRAMDATA\NOKIA\PACKAGES\PRODUCTS\RM-915\XXX.VPL"
Where the C:\PROGRAMDATA\NOKIA\PACKAGES\PRODUCTS\RM-915\XXX.VPL corresponds to the path of the VPL file under your ROM
When the progress is completed to 100%, the red screen turns green and the command is typed:
Thor2-mode Rnd-bootnormalmode, the phone will automatically restart, into normal use mode.

Okay, the tutorial is over.
