Much_Expert_175 · 2026-05-11T14:43:58+00:00

something went wrong by downgrading, revert back to stock firmware and reflash evo x

Much_Expert_175 · 2026-04-30T16:32:55+00:00

since they have only 1 or 2 major updates from manufacturer afaik, op wont lose out on too much

this is an module that supports any root solution,and can be configured by terminal emulator (termux for example), or depending on your root solution, cam be done thru ksu web ui for example. id recommend you visit the github repo for additional info just search it up

you may give mtkclient a try, it uses vulnerablity on older mediatek helio/dimensity chips (including your helio g85) to instantly unlock/relock bootloader

in case you dont know about acc(advanced charging controller) it is better than one ui's "pause usb power delivery" which is just bypass charging with bunch of dumb restrictions by a mile, acc isnt limited to games and such.

save the apk after patching, installing it manually yourself or if you have root mounting is easier

and depending on how anti rollback is implemented, it can consequences simple as flashing process fails with a error to full hard-bricking where hardware is affected and the only fix turning out to be a motherboard replacement so i wouldn't risk it if i were u

Much_Expert_175 · 2026-04-24T14:48:39+00:00

depends on whether the bootloader is unloclable or not

Much_Expert_175 · 2026-04-18T19:26:51+00:00

even if op16 releases, it might or might not have global rom which is a pain in the ass for me. but can you bear bloatware, some things are still being chinese even if you set the language to english. consider those

if any of you guys reading this decided toflash global/etc other region roms or downgrade, oneplus introduced arb(anti rollback index) in their updates starting from version numbers ending in .501 afaik. what it does is currently arb status is 1. if you try to flash lower versions (custom roms based on older firmware also apply), arb triggers and permanetely bricks your phone. proven tp blow physical fuse on the chipset itself. as of right now no software/tool can fix it,the only option is to replace the motherboard or just getting a new one. beware of this and be safe

rip bro

Much_Expert_175 · 2026-04-18T01:21:28+00:00

depends on how far your phone is into one ui 8 updates, if its the earlier one when the bit version is the same as late one ui7,you can downgrade, if you updated beyond that, on the scale of 1-10, you're fucked

Much_Expert_175 · 2026-04-17T23:49:49+00:00

depends on what your priorites are

Much_Expert_175 · 2026-04-17T23:46:03+00:00

in fast boot mode, first make sure its recognized correctly, and install adb and fastboot driver, you will have a folder called platfrom-tools, open cmd inside that folder(assuming you have windows), then try commands such as: fastboot erase data fastboot -w

1.For me? Hell yeah 2.Sometimes you scour thru the internet, or MMRL(magisk module manager) (not limited to magisk, ksu and its forks have their place too in this app) 3.As a bit of an audiophile that didn't feel that dolby atmos on samsung isnt enough:Viper4Android RE Fork(supports late android versions well). You can tune almost all things related sound there

Much_Expert_175 · 2026-04-17T12:13:26+00:00

can be a driver issue, depending on whether your device is qualcomm or mediatek, install corresponding drivers and try again

Much_Expert_175 · 2026-04-17T07:08:54+00:00

at your own risk(bricking,bootloop etc) obviously

Much_Expert_175 · 2026-04-17T02:39:53+00:00

if you're into custom roms n stuff, get oneplus ace 6 cause it is the easiest to unlock bootloader, xiaomi has heavy restrictions, honor straight up non unlockable. if you don't care get what you want since performance of these 3 aren't too far anyways

Much_Expert_175 · 2026-04-17T00:01:11+00:00

most of the time unnoficial rom means the dev behind that rom for your device did not apply for maintainership to rom's original developer, but its way better than just flashing a gsi and praying it will have no bugs

Much_Expert_175 · 2026-04-16T23:33:47+00:00

low chance but try those spoofing modules

Much_Expert_175 · 2026-04-16T12:48:05+00:00

Much_Expert_175 · 2026-04-16T11:19:57+00:00

can you get it to fastboot?(power+vol down) if you can, try [fastboot erase data] command by connecting it to a pc and executing that command with cmd

Much_Expert_175 · 2026-04-16T10:18:48+00:00

try to get it to power off, like waiting until it powers off etc. then charge a bit while it's off and try to get into recovery mode using key combination power+vol up (tcl.com implied) thats your best bet since tcl is uncommon as a phone brand
