QFIL Helper - Partition/LUN backup automation utility for LG v50/G8

QFIL Helper is a console app created out of the necessity to automate the process of partition backup with QFIL utility. As one of the “lucky” owners of the sprint branded LG v50, I was faced with the grim prospect of making manual backup of every available partition, every time I’d want to upgrade, downgrade, tamper with the system files or mess with Magisk modules.

While researching this subject, I've stumbled upon this guide explaining in great detail how to use fh_loader.exe supplied within QFIL (QPST) utility. Then I've decided to take it one step further and automate the entire process…

• The app now has access to all the info about hidden partitions and LUNs
• Backward compatibility with back-ups created with previous veriouns (except for hidden partitions/LUNs)
• Added optional NTFS compression: - NTFS
• Added userdata backup (with compression enabled, takes at-least 40 mins on a "good" hardware)

Things to remember:

⚑ Every time you make a backup with QFIL Helper, the files will be saved in: Backup-Year-Month-Day-Hour-Minute-Seconds

For Example, if today's date is 2022-07-20 and current time is 18:14:44,
then the backup directory would be named like this:

Backup-2022-07-20-18-14-44

⚑ When flashing firmware, the files must be placed in the "Flash" subfolder and named in compliance with any of the following formats:

lun#_partition_$.bin | parition_$.bin | partition.bin | lun#.bin | lun#_complete.bin
	
For example:
	
lun4_abl_a.bin - will be flashed into LUN4, Slot A
abl_a.bin - will also be flashed into LUN4, Slot A.
lun4.bin - will flash entire LUN4
