I tried to delete the abl_a file using qfil and upload it again.
The whole file has been erased so there is nothing.
Download mode is not accessible, adb is not available.
It seems that only qfil is possible to connect to the computer.
How to put the entire file back from the abl_a file using qfil
do you have?

Never delete a file, because you delete the parttion, only replace. You are mostlikelly bricked

Finally done root with my Sprint G8x with 20f.

1. QCOMM Driver need to install with option ETHERNET-DHCP (2nd option)
2. BACKUP abl_a/b boot_a/b modemst1/2
3. for fastboot driver, need [Disable Driver Signature Verification] for win 10.
4. after root w magisk, can flash back your backed up abl_a/b

Let me know if anyone wants my backup files or magisk patched boots.

Anyone know why my g8x sprint 20h bootloop after flash patched boot.My phone successful unlock bootloader.

i think hidden menu not working in sprint variant, i have sprint g8x, and other users with sprint variant say the same
Yeah, could that be, not sure though. I'm conversant with none other than "unlocked" (for any network) variants. To the extent of the variants available in India (IND and INV) I am aware of... But in a Telegram group, people could make it (I mean the "sprint" too) work...🙂

    Sprint hidden menu is 5689#*850#, but there's no Port Check Test option.

    you right, my apologies

    Interestingly, if you replace the abl_a and abl_b with the modified abl_a on a Sprint phone and reboot it, it becomes a T-Mobile phone and then getting to HiddenMenu becomes *#546368#*850# and there is a Port Check Test option.

    How to FIX Network?

    1. Boot to edl mode.

    2. Open Partition Manager in QFIL, restore backup of abl you created before flashing.

    3. Reboot, and network will be back...

    THIS IS NOT EDL MODE. (This is Download mode for flashing KDZ, many people are confusing this with EDL)

    IN EDL MODE SCREEN WILL BE BLANK AND YOUR PHONE WILL BE DETECTED AS Qualcomm HS-USB QDLoader 9008 not LGE AndroidNet Serial...
