I don't know if it's the same issue, but I find that (after the lastest update), if I plug it in, it will show warp charging after ~20 seconds, but then drop back down to "Slow charging" after a few minutes. Usually if I unplug and re-plug the cable at that point it continues to warp charge properly. Not ideal, but might work to at least charge at a reasonable speed till the dev can fix the issue.
It was showing everytime I tried to charge.. should've worked by this method, I changed rom anywaysI don't know if it's the same issue, but I find that (after the lastest update), if I plug it in, it will show warp charging after ~20 seconds, but then drop back down to "Slow charging" after a few minutes.

You could try using global firmware .Anyone using this rom and on a verizon based sim? Been on stag for a while but sim hasnt been working. Tried a couple other roms and it never worked on them either.
edit: i see above me that someone said verizon does work, but it aint for me. Sim was working while on stock but never any roms. Wasn't able to msm to proper op9 rom, but indian op9 rom would work. The sim never worked on the indian op9 firmware. Could my sim be an issue? it is a 4g lte sim but idk
edit2: i checked using an app that there isnt even a sim detected. Sim does work an older samsung phone. I remember stag would show verizon on the lockscreen sometimes. If anyone else has a verizon sim and knows of something i could be doing wrong, or a rom that works with it, would be nice to know
Actually, I managed to fix the issue by using lineage os recovery instead. Just follow the instructions here: https://wiki.lineageos.org/devices/lemonade/install (make sure to flash dtbo and vendor_boot)i already knew that part, never used OOS 12 till now didnt realise you had to do extra things to use local upgrade
uhh next problem, i cant seem to get into the latest boot.img recovery to sideload rom, get stuck on oneplus logo, goes back to stock fine when i flash stock image back over it.. le2110 model.. i have vbmeta disabled, so whats going on?? i did all steps in OP, both slots flashed etc..
Great to hear bud. all that into was just a recap of everything EtherealRemnant taught me, step by step, and brought my device back to life.the least i could do was pay the good deed forward.
Thanks for the answer!! You are the most orderly person on XDA !! You always help! One more question, if I run the partitions zip then I don't need to flash both slots in OOS C.48?Flash OOS C.48 to both slots (just flash the OTA, reboot, flash a second time), wipe data, and then follow the instructions here, skipping copy partitions (not needed if you flash both slots):

I don't think the copy partitions zip always works. I bricked my device twice when I was using it to flash ROMs which then worked the second time following the exact same instructions and flashing the OTA to both slots has yet to fail me but it's up to you. If it works, it saves you some time but if it doesn't, MSM back to stock and upgrading again takes even more time. For me, I will always just flash the OTA to both slots because it hasn't been a problem and I haven't seen anyone else have a problem doing it this way either.
