i think i didnt flash engineering abl to a and b,i only backed up,probably, but i used keys to get into fastboot but nah,didnt work
The stock abl's don't have fastboot. No matters what keys you use, with the stock abl, you'll never get to fastboot.
fastboot devicesin that command prompt. it should show "LMG850UM fastboot"
fastboot flash frp frp_verizon.imgthen
fastboot oem unlock
fastboot flash abl_a abl_a.bin
fastboot flash abl_b abl_b.bin
Ok, so maybe you unlocked the bootloader, still not sure. But you didn't even root? How do you consider this a success then?
Well, to answer the first part of your response here are a couple images (jpg type)
And for the rest of your response, I am going to try to finish out this tutorial this morning. I can say this much in advance: I have found that once a phone has been bootloader unlocked, gaining root (whether it be by magisk, the ol' SuperSU, or whatever) becomes an eventuality of overwhelmingly high likelihood of success. I am saying 'high likelihood' only because I realize that there are never any absolute guarantees in XDA, and it's not a good idea to jinx yourself by getting overconfident. So I'm gonna try to get rooted here and keep my fingers crossed, but I personally can not recall ever hearing of a phone whose bootloader is unlocked, that couldn't be rooted.
can't access download mode. getting waring that the phone didn't pass safety check and keeps on booting to fastboot mode. any help will be greatly appreciated. was trying to root and this happened. bootloader is unlocked. can access fastboot but no download mode. V500N
