Hello folks, it all started with the N5X stuck on google logo and now it wont turn on anymore. Red flash light will blink and phone is sometimes recognised as Qualcomm HS-USB QDLoader 9008.

Will doing this procedure wipe out the internal sdcard / data storage? My sister needs to retrive important data from this suddenly dead phone. We really dont care about the phone.

Phone is non rooted, bootloader unlocked. At least I need to restore bootloader functionality to try an attempt anything else. Than again, phone wont turn on.

Any help will be appreciated.

Boardiag will work with empty emmc without any problems. I'm writing from n5 with today soldered emmc from dead LG g4 (emmc v5 I think). All programming done with boardiag only, just dump phone specific partitions from old emmc (IMEI) if phone still can be powered on and after emmc change only software you will need is boardiag.

I'm not 100% sure how my partition tables were screwed up. But maybe one was previously off and runing the repartitioning flash somehow brought it to light.

Anywho, I wound up following this to restore my partitions. I had to modify a bit in order to work on my windows 10.

I had to remove all C++ libraries from "remove software" and install just this (i'm on windows 10).

Could you elaborate a bit on what you've done?
I'm trying to do exactly the same, fixing my working n5 which has a repartitioned /cache


I'm on windows 10 (in a vm) and the device doesn't show under com ports, only as bootloader or android device.


Thanks!

To be completely honest, I don't recall. I believe I uninstalled any some packages and installed the one that downloaded when you clicked the link I provided. It was a while ago.

OK, thanks for your quick reply!


I'll fiddle a bit more, trying to get ubports on the nexus but /cache has been recreated in the past and is too small now.

    Requirements:

    • Bricked Nexus 5
    • EMMC should not be fried
    • Image files: 16GB (mirror) and 32GB (mirror)
    • BoardDiag (mirror) tool for Nexus 5
    • Windows XP - 7 - 8 - 8.1 (Virutal Box or VMware good too)
    Let's start!
    • Connect the phone to your PC
    • Open Device Manager

    1: Find Qualcomm HS-USB QDLoader 9008 device under Ports (COM & LPT) and note the COMxy port (in my case it is COM3).
    If you dont see Qualcomm HS-USB QDLoader 9008 click on the CLICK TO SHOW CONTENT button bellow, otherwise don't and follow the guide.

    y_www.kepfeltoltes.hu_.png

    1: If you see LG Android USB Device under Other devices or LGE AndroidNet USB Serial Port under Ports (COM & LPT), then press VOLUME_UP+VOLUME_DOWN+POWER keys until you see QHSUSB_BULK under Other devices or Qualcomm HS-USB QDLoader 9008 device under Ports (COM & LPT).
    z_www.kepfeltoltes.hu_.png

    1: If you see QHSUSB_BULK under Other devices, then you have to install drivers (mirror). Just click on Next, Next... and Finish.
    You have to turn off driver signature enforcement if you are using Windows 8 or Windows 8.1 to make the drivers work.

    • Extract the downloaded images 16GB.rar or 32GB.rar to get the image files
    • Start BoardDiag
    3_www.kepfeltoltes.hu__www.kepfeltoltes.hu_.png

    1: Select Nexus5 (MSM8974_HammerHead).
    2: Select the Com Port you see in Device manager (in my case it is COM3).
    3: Select the 16GB or 32GB folder.
    4: Select AP check.
    5: Select RESTORE BOOT IMG.

    1: Click on START.
    5_www.kepfeltoltes.hu_.png

    If you were successful you should see Boot images download completed.
    Your phone should turn on, but it may stuck at Google logo. If it is stucked at Google logo you have to reflash a stock rom. You can use either LG FlashTool or fastboot method. You can also flash custom rom from custom recovery if it didn't get replaced by the stock recovery, otherwise flash custom recovery from fastboot.

    Extra fun

    I want to make a little comment about this boarddiag tool, and how it works.

    Emmc test:
    Erase: erase the whole emmc. Even if you select a partition from the dropdown menu,
    Read only: Only reads random blocks from the emmc. If you check DUMP it will read back the amount of blocks of a the chosen partition given in the partition.txt
    Write only: writes dummy data to the emmc (55AA hex values and some other other random writes on the actual partition).
    Read/Write: writes dummy data to the emmc (55AA hex values and some other other random writes on the actual partition) and then verify them by reading it back​

    SDRAM test:
    I think this test the memory. There is a Level option for it. I dont know what is the differance between the two.​

    PIMC ON:
    No idea, but in some LG documentations it is for only APQ8064 chipset.​

    Restore boot img:
    Restores the images.​

    How it know which partitions have to be restored?
    There is a rawprogram0.xml in model\Nexus5 (MSM8974_HammerHead)\boot_partition_info folder.
    The partitions declared here will be flashed to the device if you select nothing in the partititon dropdown menu or in the restore boot img dropdown menu
    Boarddiag only cares about the "label" value (have to be tha same as in partition.txt) from rawprogram0.xml. The rest info like startblock, files size and file name will be acquired from the partition.txt.
    Partition.txt is a binary file:
    0x00-0x03: start block
    0x04-0x07: file size in block numbers ( 1 block = 512 byte)
    0x08-0x0F: always zero
    0x10-0x2F: partition name (must be the same as the label value in rawprogram0.xml)
    0x30-0x4F: file name
    and the pattern goes on.​
    I wrote a little program which converts this binary partition.txt to an actual txt. You can get it from here
    Copy the partition.txt to the same folder where the bin2txt and txt2bin exes are. Run bin2txt then it will create a readable_partition.txt file. Edit it with notepad++. The start block is in HEX and the file size is in bytes (must be multiple of 512). Partition entries is the number of partition declared in the partition.txt. If you done with the editing then run txt2bin and it will create a new_partition.txt file.​

    The tool is working. I tested on my nexus 5. I dd zeroed out the sbl1 partition. The phone refused to turn on no matter what I do. I did that what is shown in my first post and now the phone is working again. I also tried to help a guy, but it turned out the emmc of his phone has an I/O error. I used the EMMC TEST option to check the emmc for bad sectors.

    I am also summoning @rootSU to let him know what a cool stuff nexus 5 has.

    It is fine to do the r/w test. Better to check the SDRAM test too because after a successfull emmc test the bootloader will be not restored then you have to hold the powerkey until you see the qualcomm qdloader 9008 device disappearing and reappearing again or removing the battery connectors if that not works. So if you check the SDRAM test too then it will restore bootloader. Keep in mind that SDRAM test takes about 5 minutes and also during this time your phone will not show up in the device manager. Just be patient the phone will reconnect when the test is done.

    Can we adapt these procedures for other devices. If we can how to go about it ? What files are needed and how to get them from a similar device?

    Maybe. What you will need:

    Flash programmer
    Essential images to make the phone boot. These are the generic: aboot, sbl1, (sbl2, sbl3), tz, rpm, boot, and there are some other necessary partitions which depends on the device for LG phones it is the laf. You will need the primary and backup GPT too if you want to fix them too.
    Edit rawprogramm.xml
    Make a partition.txt

    The choke pont is to find a working flash programmer for you device.

    But you can try an SDcard method. Some LG (like LG F460/LG G3 Prime,/LG G3 Cat.6) and Samsung (Note 3 ???) boots to download/odin mode if you make an emmc dump of a working phone and raw write that image to an sdcard. The dump size is determined by the start block of the system partition.
