Only for QHSUSB_DLOAD lumia (black screen, no vibration)

I got my lumia 620 hardbricked about a month ago while rolling back to windows 8.1 from windows 10 tech preview for phone .
i know there is a shit loads of people having their dead phones with them in the dust. about 2-3 days ago i came to a post which got myself a fully functional phone from a toy to my brother.

ONLY THING YOU NEED IS A NEAT INTERNET CONNECTION AND A SPARE TIME

so down below are the steps i followed .
first you need to download some files like drivers and the softwares .

DOWNLOADS

Drivers

X2_FlashDriver_Emergency_XP.rar (up to windows 8 32b)

X2_FlashDriver_Emergency.msi (windows 8 64b)

Nokia_WP8x_NXP_MTKx_Asha.rar

HEX files (subject of changes, please tell me about newer versions)

We only have hex files for x2x lumias (excl. 1520)

Confirmed_HEX.zip confirmed working RM 846, 892, 820, 821

Alternate_HEX.zip nearly all hex files we have

MPRG_HEX.zip

Software

WPRT (contains thor2.exe)

WindowsPhoneRecoveryToolInstaller.exe

Data Package Manager

Nokia_DataPackage_Manager_2013.7.5_fixed

important folders: (dont worry if you don’t have them : i didn’t had them either :P) but helps if you do have them

C:\ProgramData\Nokia\Packages\Products

C:\Program Files (x86)\Microsoft Care Suite\Windows Phone Recovery Tool

C:\Program Files\Microsoft Care Suite\Windows Phone Recovery Tool

64bit OS  32bit OS

DOWNLOAD ROM
install Nokia DataPackage manager and  fix pre dpm  (DataPackage Manager)

locate this label on your phone and write down

Type e.g. RM-846

Code e.g. 059S2G1

If you can’t find it, try searching here

launch DPM, if asked for login, select something from dropdown

enter your Type and Code, press search and click download (the play button)

 

after it’s 100%, we are done with DPM

INSTALL DRIVERS

install WPRT and all drivers from Nokia_WP8x_NXP_MTKx_Asha.rar

create C:\lumia\ folder (important)

We need to install/replace QHSUSB_DLOAD driver

open Device Manager – devmgmt.msc

look for QHSUSB_DLOAD

 

right click, uninstall and tick Delete driver software

now you should have

 

Windows 7 (Try win 8 part, should also work on win 7 and tell me)

extract X2_FlashDriver_Emergency_XP.rar to C:\lumia\driver

right click on , update driver, browse my computer, type in C:\lumia\driver

click next, if asked to install unsigned driver, confirm

 

Windows 8

Install unsigned drivers in windows 8

or

Install X2_FlashDriver_Emergency.msi (please confirm this works)

click in device manager

FLASH BOOTLOADER

(if you don’t undrstand how to edit following commands i attached some screenshots at THE BOTTOM; zoom it and help yourself :P)

We need to extract GPT0.bin, which is in the software we just downloaded

open Admin command prompt (cmd.exe). Commands to enter are Yellow

cd C:\Program Files (x86)\Microsoft Care Suite\Windows Phone Recovery Tool

locate FFU file in C:\ProgramData\Nokia\Packages\Products and change the red part below
thor2 -mode ffureader -ffufile “C:\ProgramData\Nokia\Packages\Products\rm-XXX\rest_of_path_to_file.ffu” -dump_gpt -filedir C:\lumia\

look for this in command output, this is your RootKeyHash (RKH) (THOSE TWO BIG LINES DOWN IN THE SCREENSHOT), save it for later

you shout get two files in C:\lumia\

open  Confirmed_HEX  and  Alternate_HEX  and  MPRG_HEX

look for hex file with same name as your Type

if you can’t find it, look for hex file with name matching your RKH

and copy it to  C:\lumia\ and rename to HEX.hex

 

flash the bootloader

thor2 -mode emergency -hexfile C:\lumia\HEX.hex -mbnfile C:\lumia\GPT0.bin -orig_gpt

Reboot the phone

if you get Red Screen with NOKIA logo go to FLASH SYSTEM

SAFE hex file was used and unallowed memory address was being written

PROBABLY means bootloader flashed (for RM-846)

Reboot the phone (pull usb and battery out OR hold power for ~15s)

If you still get QHSUSB, try again. You should get Red screen in 5 tries

After you get Red Screen with NOKIA logo continue below

THOR2_ERROR_CONECTION_NOT_FOUND
means Phone not detected   common cause is incorrectly installed driver

THOR2_EMERGENCYFLASHV1_ERROR_PROGRAMMER_SEND_FAILED

THOR2_EMERGENCYFLASHV1_ERROR_MSG_SEND_RECEIVE_FAILED
means invalid/wrong hex file

FLASH SYSTEM

You have to charge the device first. Connect it to charger (not PC) and let it sit for 30mins

flash FFU:

thor2 -mode uefiflash -maxtransfersizekb 256 -ffufile “C:\ProgramData\Nokia\Packages\Products\rm-XXX\rest_of_path_to_file.ffu”

optional use only after flashing failed multiple times (Scenario 1)

 

when you get to 100% and get Green Screen on your phone, you are almost done

now just reboot to windows

thor2 -mode rnd -bootnormalmode

First boot takes a long time and seems to have no progress

at first, there is small white NOKIA logo

then black screen with backlight on

this took about 15 minutes on lumia 620, 3 minutes on lumia 520

 

Scenario 1: many fails

It will reach ~5% and then crash. Reboot the phone (hold power for ~15sec) and try again

Now it may reach 10%, next time 15%, then 20.

Above 20 it increments by 10%.

Eventually it will get to 100%

Scenario 2: no fail

It will go straight to 100% with no crash

D_ERR : Rebooting from the WP/MMOS failed

Reboot the phone

FA_ERR_FFU_SEC_HDR_VALIDATION_FAIL

0xFA001106: Signature check of FFU file fails

currently unfixable, unknown cause

Failed to read number of eMMC sectors. eMMC is not working

Might be fixable with JTAG (phone repair shop)

FFU signature invalid

have you downloaded the right FFU with Nokia DPM?

In case your broke while “downgrading” from W10, you’ll probably have to wait until W10 ffu is released.
