The battery of my phone is not removable, and I do not know how to connect it, it should charge rebooted or connected to the pc but it does not charge, so I ask if it is already hardware problem of my phone lumia 1320.

Regarding your problem, have you tried the emergency files that are left at the beginning of this topic?

I will leave the command that helped me to recover my device from the emergency state, maybe it will help you:

Code:

thor2 -mode emergency -hexfile %HomePath%\Desktop\YOUR_HEX_FILE.hex -mbnfile %HomePath%\Desktop\YOUR_MBN_FILE.mbn -ffufile %HomePath%\Desktop\YOUR_ROM_FILE.ffu -skipffuflash
The problem continues... help please.


Now when I connect it by usb, the phone disconnects and connects every two minutes and does it again and so on, the phone is in flash mode (NOKIA FLASH). I am afraid to flash it in this state, will there be any solution, the usb ports are in good condition and the usb cable too.

I have bought the universal charger that was posted earlier, and I'm charging the battery.

Still haven't got any idea on my 730, i've charged it using charger from previous post, it still stuck on DLOAD. When i flash it, it's okay, but fails with FAILED_TO_BOOT_FLASHAPP after reboot. It's not emmc, since i've killed boot handy when attempted to unlock bootloader(and loosened cable). However, i've noticed some strange things:
Battery is charged MAX to 75%. Probably battery is just loosing it's charge(2015 year), so can i try to connect some other nokia battery and flash from there? Also tried to flash without battery, no luck. May be try press some buttons? Found few topics about my phone on xda, and people successfuly restored their devices but without any files or mentions.

Hi, does that mean memory failed? Can't you get up to it already?

I think you need to use windows recovery tool, sometimes this commands don't work.

this command will create gpt0.bin and rename it as msimage.mbn

mine was F771E62AF89994064F77CD3BC16829503BDF9A3D506D3FACECAEF3F808C868FD so my hex file in binary format was F771E62AF89994064F77CD3BC16829503BDF9A3D.bin
I don't understand these step. I see gpt0.bin in C:\dump folder but there's no msimage.mbn. Am I supposed to manually rename it?
And where can I find this string F771E62AF89994064F77CD3BC16829503BDF9A3D506D3FACECAEF3F808C868FD? I don't see anything like it in C:\dump.
Still get my Lumia 930 brick for 8 years or more, don't even remember, I bought it since it's released.

I tried to unbrick my Nokia Lumia 720 and it's fixed LOL, I have some error with thor 2 but after I removed battery and install right driver and it's worked LOL!
My phone has been felt to QHSUSB_DLOAD after I used Windows Phone Internals to unlock bootloader, and I think I have put wrong bootloader hex file... or something.
command: thor2 -mode emergency -hexfile FAST8930_RMxxx.hex -mbnfile RMxxx_msimage_v1.0.mbn -ffufile RMxxx.ffu
the ffu you can download on lumia firmware:
First install Windows Device Recovery Tools from Microsoft, or you can download in thread 1.
And secondly, install the QHUSB driver because the Lumia use Qualcomm SOC, so you can you any Qualcomm USB driver.
And driver is QHUSB: https://androidfilehost.com/?fid=674106145207490601
NOTE: IF YOU USE WINDOWS 8 OR 10 YOU NEED TO RESTART TO ADVANCED BOOT OPTION TO INSTALL UNSIGNED DRIVER BECAUSE THIS DRIVER IS OLD ENOUGH.
and all Lumia hex file I collect from someone on Youtube:
you need to put the all file needed to C:\Program Files (x86)\Microsoft Care Suite\Windows Device Recovery Tool\
and run the command:
thor2 -mode emergency -hexfile FAST8930_RMxxx.hex -mbnfile RMxxx_msimage_v1.0.mbn -ffufile RMxxx.ffu
It's error or not, don't worry disconnect the battery and turn power on.
flash the ffu file with WP internals: https://windows-phone-internals.en.lo4d.com/windows
You can search how to flash default FFU on the internet.
with xxx is the model of your phone.
if the link died, tell me. I will update soon.

Peace!

Try to install Qualcomm driver I used in my thread and use thor2.exe to detect phone. I have the video for tutorial on YouTube, link in the below the thread. Let try it!

    And THE WAIT IS OVER ... after almost two months without telephone, as this has happened to me in February, with the help of you... have achieved UNBRICK LUMIA DEVICES WITHOUT JTAG ONLY WITH USB. Thank you, thank infinitely.

    Warning: use this tutorial at your own risk, I do not responsible of anything. To me it worked.

    05/25/2015
    Simple method:

    Yesterday update to WPRT 2.10 was released, which is able to fix DLOAD scenarios for lumias.
    Here is the link.

    --------------------------------------
    If this does not work, try the advanced method:

    Let's to the steps:
    Attachment files in the same thread.

    1) Install Thor2 (incluiding on WPRT): http://go.microsoft.com/fwlink/?LinkID=525569
    2) Download your firmware lumia with NaviFirm
    3) Install Drivers
    4) Go to the folder where it is thor 2 from cmd (run administrator)
    cd C:...

    Use this command line to extract gtp0.bin from ffu image

    Code:
    thor2 -mode ffureader -ffufile "C:\rm-914\XXX.ffu" -dump_gpt -filedir C:\dump

    this command will create gpt0.bin and rename it as msimage.mbn

    mine was F771E62AF89994064F77CD3BC16829503BDF9A3D506D3FACECAEF3F808C868FD so my hex file in binary format was F771E62AF89994064F77CD3BC16829503BDF9A3D.bin

    convert this binary file to hex using bin2hex.exe

    Code:
    bin2hex F771E62AF89994064F77CD3BC16829503BDF9A3D.bin HEX.hex

    open .hex file in notepad
    insert :020000042A00D0 in first line
    and :040000052A000000CD before the last line

    or
    Hex files already created starting in the bin, use RESPONSIBLY depending on your Lumia device


    Now you have HEX.hex and msimage.mbn

    the use this command line

    Code:
    thor2 -mode emergency -hexfile HEX.hex -mbnfile msimage.mbn -orig_gpt

    Ready, disconnect the battery and reconnect. Now connect your phone to the PC
    Yeah, his phone started life with red screen!
    Charge the battery

    5) Flash rom: Now, in the case of Lumia 520/521

    Code:
    thor2.exe -mode vpl -maxtransfersizekb 1 -vplfile C:\ProgramData\Nokia\Packages\Products\rm-915\XXX.vpl

    .VPL remember it is not ffu. After the process 100%, your device turn with green screen, and:

    Code:
    thor2 -mode rnd -bootnormalmode
    :highfive:


    Some versions of Lumia, especially Lumia 820, 920, 920T, 925, 1020 (several models) have different .HEX, attached in the correct thread files ''CorrectedHexFiles.zip''

    draft for steps

    STEP 1 - find RootKeyHash and GPT.bin

    locate your FFU file. If your phone bricked during Downgrade, you should have it in
    c:\ProgramData\Microsoft\Packages\Products\rm-XXX...
    or
    c:\ProgramData\NOKIA\Packages\Products\rm-XXX...

    It should be best if you have the Windows Phone Recovery Tool updated to 1.2.4

    then go to the Microsoft / Windows Phone recovery folder (thor2.exe is there)
    c:\Program Files (x86)\Microsoft Care Suite\Windows Phone Recovery Tool\

    open up command line there, and make the dump in folder of your choice

    Code:
    thor2 -mode ffureader -dump_partitions -ffufile "RM9xx*.ffu" -filedir "c:\dump"

    the log will display also the hash needed for you to find correct HEX file

    Code:
    Number of partitions found 28
    RKH of SBL1: F771E62AF89994064F77CD3BC16829503BDF9A3D506D3FACECAEF3F808C868FD
    RKH of UEFI: F771E62AF89994064F77CD3BC16829503BDF9A3D506D3FACECAEF3F808C868FD

    also, the files are large, becaue the above step will make complete dump
    you only need GPT.bin which is around 250 KB so get this file only

    STEP 2. find the HEX file in the archive attached here

    it is named with name starting as the RKH from previous step.
    it is the first 40 bytes, so in the example
    F771E62AF89994064F77CD3BC16829503BDF9A3D506D3FACECAEF3F808C868FD
    is infact
    F771E62AF89994064F77CD3BC16829503BDF9A3D.hex

    STEP 3. try to get RED screen

    Code:
    thor2 -mode emergency -hexfile bin.hex -mbnfile gpt.bin -orig_gpt

    the process above will not finish with success, as the provided GPT file is not only file needed to flash it. so I tried to flash it several times, reseting the phone ... etc., after 3-4 times, the phone vibrated, with red screen

    STEP 4. flash your phone FFU image
    Code:
    thor2 -mode vpl -maxtransfersizekb 1 -vplfile "C:\ProgramData\Microsoft\Packages\Products\RM .... \* .vpl"

    don't forget the -maxtransfersizekb flag because this flag perhaps was omitted in the Microsoft tool, making the flash procedure stop in the middle

    I tried to unbrick my Nokia Lumia 720 and it's fixed LOL, I have some error with thor 2 but after I removed battery and install right driver and it's worked LOL!
    My phone has been felt to QHSUSB_DLOAD after I used Windows Phone Internals to unlock bootloader, and I think I have put wrong bootloader hex file... or something.
    command: thor2 -mode emergency -hexfile FAST8930_RMxxx.hex -mbnfile RMxxx_msimage_v1.0.mbn -ffufile RMxxx.ffu
    the ffu you can download on lumia firmware:
    First install Windows Device Recovery Tools from Microsoft, or you can download in thread 1.
    And secondly, install the QHUSB driver because the Lumia use Qualcomm SOC, so you can you any Qualcomm USB driver.
    And driver is QHUSB: https://androidfilehost.com/?fid=674106145207490601
    NOTE: IF YOU USE WINDOWS 8 OR 10 YOU NEED TO RESTART TO ADVANCED BOOT OPTION TO INSTALL UNSIGNED DRIVER BECAUSE THIS DRIVER IS OLD ENOUGH.
    and all Lumia hex file I collect from someone on Youtube:
    you need to put the all file needed to C:\Program Files (x86)\Microsoft Care Suite\Windows Device Recovery Tool\
    and run the command:
    thor2 -mode emergency -hexfile FAST8930_RMxxx.hex -mbnfile RMxxx_msimage_v1.0.mbn -ffufile RMxxx.ffu
    It's error or not, don't worry disconnect the battery and turn power on.
    flash the ffu file with WP internals: https://windows-phone-internals.en.lo4d.com/windows
    You can search how to flash default FFU on the internet.
    with xxx is the model of your phone.
    if the link died, tell me. I will update soon.

    Woohoo!!!! Success with my RM-893! Skiddd thanks for the bin package! Not sure where you got the RM-892 bin but I've tried several before yours and they didn't work but yours did!

    I converted to hex then had to do the edits since that one is larger than 60kb and now my phone is back to life! I've posted the edited file here for anyone with an RM-892/3 that wants to try it!

    Now in every new Lumia from Microsoft there is way to force device to switch into emergency flash mode:
