a) install userdebug gsi (phh, los, leos etc) with dsu sideloader apk from github

or

b) take any recovery for your phone and change prop values for adb root in recovery

ro.secure=0
ro.adb.secure=0
security.perf_harden=0
ro.debuggable=1
persist.sys.usb.config=adb,mtp

boot into gsi or recovery

adb root
adb pull /dev/block/by-name/boot
this method has problem

change rhe prop of reocovery.img

EX)
chaning prop 12.0.14.4 recovery.img and flash to 12.0.14.5 device is working fine.

but when I flash to 12.0.16.6 device
with same 12.0.14.4 recovery.img

it has bricked.

So I flashed original recovery.img of
12.0.14.4

it is bricked status

So I send china, get mainboard change.

I guess if we want to get boot.img from flashing recovery.img

middle version (14. / 15. / 16. ) is important.

well, you have unlocked BL and working fastboot, right?
Yes enter to fastboot and bootloader is all fine
just can not go to recovery or Main UI

so I sent china and get repaired.

in this case what can we do?

we are using this method (changing prop of recovery.img) because we can't find newest firmware at all place.

so we can not flash current version's recovery.img
to replace all images of original current version

PLS give us the method to solve :)

If same problem has come again, we have to send china again :(

1) start downloading of ota update, wait for some time, then

mount /bin /data/vivo-updater
it's should prevent system from checking ota.zip (but shouldn't stop download), otaupdate will be hidden - no file - no reboot

umount /data/vivo-updater

then copy
(this method most likely will work, I'm not 100% shure)

2) right after download you can try

su -c setprop ctl.restart zygote

from pc or whatever

(warm reboot should also prevent ota.zip check)

3) alternative should be pressing vol+ when phone reboots, so you will be booted into fastboot

then

fastboot erase misc

(misc partition contains commands for installing update after reboot)

I don't know what it is (I don't own x80), but you should be able to boot in recovery with right vbmeta

You tried to boot in recovery 12.0.14.4, but you had vbmeta for 12.0.16.6

Flashing right vbmeta should have helped you, also you could try to flash vbmeta with flags disable-verification disable-verity

ps. having unlocked BL and working fastboot means that your device isn't bricked (in most of the cases)

tested->>>

mount /bin /data/vivo-updater

this prevents reboot and installation on my vivo y31

umount /data/vivo-updater

then copy ota update

No. there is no person that try to flash global rom

and some amazing man try to flash
X70 pro+ CN -> GLOBAL
his device had hardbrick.

PLS do not try to flash :)

if MR. pervokur will know :)

Global Rom over CN absolutely can't be done via Recovery.
Mandatory is to not flash Modem files, the phone will break and brick.

A Global Rom over CN can be done editing the Chinese System image using the Global system files...
reconstruct the system.img creating a sort of Frankestein System... and then flashing It to deceive the system.

if you can install this vivo apk, then there is hope... it's uid1000 debuggable app from vivo

how to use this https://forum.xda-developers.com/t/...t-not-root-how-to-escalate-privilege.3417498/

commad to activate factory mode in order to run "upgrade/downgrade sw" in activity from com.iqoo
engineermode

print new java.lang.Runtime().exec("setprop persist.sys.factory.mode yes")

Of anyone able to do this, then I can try help with others things

    Hello. sorry for my bad english

    I have X80 PRO, X70 PRO PLUS, X NOTE

    ALL CN MODELS
    and one Global Ver X80 pro

    and I unlocked bootloader X70 PRO+, X NOTE with this thread


    but only X 80 pro is not working with those method.

    I have one CN model, two GLOBAL(singapore) model.

    CN model - S/W version is PD_2185_A_12.0.11.7
    GLOBAL - S/W version is PD_2185F_EX_A_12.0.11.8

    both ORIGIN OS, FUNTOUCH OS are not unlockable.

    anyone did bootloader unlock??

    When you said the method that worked for your x70 doesn't work for your x80, what do you mean by doesn't work?
    Did the unlock command return OKAY and then it was still locked?
    Or did it fail with some error message? If so, what's the error you're getting?
    X70, I unlocked Bootloader.

    and with same way
    X80 failed
    CN and Global both failed

    unlock cmd said Okay
    flash cmd said failed (check signature~)

    and press power button and it reboot to UI

    so I try agian,
    unlock cmd said Okay
    flash cmd said failed (too many links)

    and try agian
    unlock cmd said failed (max download size~~~)
    flash cmd said failed (check signature ~)

    So I totally have no idea how to unlock BL
    the way of unlocking doesn't work

    You mentioned in one of your posts that you also have the Vivo X Note. Did the X70 unlocking method with on it?
    Yes X note can unlock BL with X70 unlock method

    At least I could unlock global X80 Pro.
    You can use this Android 12 rollback ZIP to downgrade fw to "2022-04-01" patch level.
    For global X80 Pro, I had to update to 13 Beta first, then reboot to recovery to install rollback zip.

    hmm, there's risk for brick... It seems progress bar is 0% so if it's failed before actual installation process, you'll survive.
    amazing....
    you are the best...!!!!
    I stopped update and it is reupdate automatically
    and after I downgrade 12.0.11.2 with recovery.
    I can unlock BL :)
    really thanks to you
    one more time, you are the best
