[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] DeepPurple72:
sorry i had the cid backwards. lol. its the cid 11 thats locked BL. the CID 15 can be unlocked. minebis cid 11.

dont flash the g900v via odin!

flash the sm-903vl factory test 4.4.2 md5 via odin AP

root with pc using kingroot windows version - internet required!

install busybox

extract the system & cache files from the G900v KK 4.4.2 AP file ( after extracting the main md5

use simg2img & create the system.img & cache.img files

copy to phone internal sd

adb shell

su

stop

etc....

basically, same steps as the 902L , but using the files from g900v instead. i think that you must use files from kk rom, since only the /system & cache files are written to phone via 'dd' commands. its not "flashing" other partitions, such as data, BL, recovery, csc, etc.... its overlaying system files to "upgrade" factory test 4.4.2 to a "full" version. idk if 4.4.4 kk will work or not. recommend 4.4.2. but feel free to experiment.

then root g900v via towelroot apk

install busybox, fix apn via phoneinfo.apk if no data, etc

i posted exact steps here: https://xdaforums.com/verizon-galaxy-s5/general/tutorial-root-sm-903vl-downgrading-to-4-t3580168

i dont think its possible to root 6.01. the kernel & security updates & SElinux wont allow 'su' to run... at least thats true with PH3 build. i may have read a previous 6.01 was rootable either by KR or TR. If its even possible to downgrade from ph3.

maybe from factory test 4.4.2 you can odin the md5 of the 903vl mm 6.01 that is rootable? idk.

idk about g900v lollipop - im guessing it prob wont work.

root is achieved on sm-903vl by downgrading to factory test 4.4.2.... but its test rom. dumping the system & cache from a compatible ROM gives you a full KitKat version with root. upgrade or flash another stock rom, and goodbye root.

i havent played with safestrap for g900v ( which should work on sm-903vl also ). personally, id like to run Lineage rom on mine vis safestrap, if it will even work. has anyone tried that?

If you could downgrade to factory test 4.4.2, and then flash an early version of 6.01 ( not PH3 ), that can be rooted with kingroot, stock kitkat 4.4.2 ( or maybe safestrap ) only way to get root on the locked bootloader. any attempt to flash custom recovery like twrp or custom kernels (boot.img) and you brick your phone.

you can flash BL, but only official stock ( signed ) bootloaders.

It took a very long time to download the roms, get it to where 902l was rooted, busybox, xposed, lucky patcher, viperfx & viper xhifi, ie.. setting up the phone.

902l kk running on my 903vl very good. just no mobile hotspot, and fingerprint reader dont work. data, wifi, sms/mms, bluetooth, phone calls all working good. it even natively usb tethers w/o 3rd party Apps too ( after some hacks ).

one more VERY important thing!!!!

BEFORE running playstore updates, use lucky patcher ( or titanium, or other root app that can freeze/disable packages )

Disable the Security Update package!!!!!

if you let it update, you may lose root and have to start all over from scratch! be warned!
