No, you must first write the wallaby patch tool to SD card (using 1k header), insert it, and put it into bootloader. The patch tool will then present its menu, and you can choose to read bootloader from SD (written with a 4k header), and then you're all set.
isit possible for me to downgrade to bootloader 5.15??
I've tried using XDATools by Jeff Summers but it just wouldnt let me downgrade...
is there any other way??
Hi,
Yes, it is possible to downgrade from bootloader 5.17 to 5.15 by using "Fix Broken Bootloader" program part of the XDAtools, as long as you have Activesync connection.

I've never done it before but from what I heard XDAtool can be use to downgrade the boot loader. For more info. on XDAtools visit the Forum Index and look under ROM Upgrades for XDAtools.

Hi Adaoud,
I did successfully downgrade from 5.17 to 5.15 for the same reason you have using the "Fix broken bootloader" of the XDAtools.

I downgrade from 5.22 to 5.15 and upgrade 5.15 to 5.22 many times without problems!
Can you tell me how can i do this please?
Hi,
Is there an expert out here, who knows how to dump the file system from bootloader mode?
thanks,
I know that some variants can't be unlocked,
but what if we downgrade with lgup and edz files, root using an exploit usable on the downgraded version, and then use su to dd an unlocked bootloader (extracted from a lucky guy that had the unlock.bin from lgdevs for the same model). Will it not boot because of imei or unique device ID ? Or worse the bootloader partition isn't r/w from the root ? Just asking because I don't really know how work the protection on Android.
