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, specifically the H918 T-Mobile variant, I created a TWRP flashable package for the recent H91810q 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 10q is not rootable,failure to do so will probably cause you to lose root and/or lose TWRP!  and worst of all, because 10q can't be downgraded to 10j (last version where you can still obtain root via dirtycow) because of Anti-RollBack, you're fscked!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 stockold 10q md5sum:new 10q md5sum: c7d4086b3a0a786d1501ef7e4ce22f32 - re-zipped in Linux for proper alignmentwrong 10r md5sum:(this is actually the md5sum for the KDZ)correct 10r md5sum: 194b2bc41aa6dbdd7b9a371392f7b93010s md5sum: f187fdefe4c3612c5811e9fbeb0748c5 H91810t.zip - rctd and triton both disabled, previous versions only removed rctd10t md5sum: b00c2f644b15eb15e459c48830caa5da H91810u.zip - rctd and triton both disabled, previous versions only removed rctd10u md5sum: f51b2b11a30dc448b0da0edc750bb587BIG 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
