Flashing Process (what flashing this zip does):

flash necessary partition images with the exception of recovery (to keep TWRP) from the KDZ rename /system/recovery-from-boot.p to /system/recovery-from-boot.bak to prevent stock recovery from being installed on boot wipes dalvik-cache and cache

with very little activity lately for the LGV20, especially with the unlocked US996 variant, I created a TWRP flashable package for the recent US99610k release. this zip flash every partition included in the latest KDZ package with the exception of recovery to keep TWRP. standard disclaimer applies, you do all of this at YOUR OWN risk! because I have not tested this yet, I can't verify whether 10k is rootable or not or if there's Anti-RollBack (ARB),failure to do so will probably cause you to lose root and/or lose TWRP! if 10k does have ARB you won't be able to downgrade. stay tuned on this.NOTE1: you can find the partitions that will be flashed in the updater-script. to be extra cautious you can back up all of the partitions that will be overwritten with the following: dd if=/dev/block/bootdevice/by-name/{partition} of=/external_sd/backup/{partition}.img.NOTE2: boot partition has been modified only to remove rctd, nothing else so I consider this to still be stock US99610k.zip md5sum: 26da82660579673e5486e0361ff8c6e6 US99610l.zip md5sum: 01423ade5ba4977e1e8ae6d5bc244ecf US99610n.zip* md5sum: bbde6e972305918712b3c51f03a1be10 US99610o.zip md5sum: 6019e92c6e0b3691689820b43b2b0c5d US99610p.zip md5sum: 9875e4da163168c84ce479509bf7e19d US99620f.zip* md5sum: 3AEBED11462D0F4A18D3FB9A4FDE95EB* - unlocked non-US Cellularfor 20f (Oreo) please see this comment about updating TWRP and /data encryption https://www.reddit.com/r/lgv20/comme...m_twrp/ed5olp6 BIG thanks to @ McNutnut on guidance, as well as his script to put all of this together!also thanks to @ bullghost for the KDZ extractor ( https://forum.xda-developers.com/sho....php?t=2600575 Tilde88 for the original updater-script template w/root ( https://forum.xda-developers.com/v20...-v5-1-t3526542
