@lilddd

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.

I guess soemting goes wrong...

if I stop updating now

[Vivo X80 Pro] AndroPlus:
hmm, there's risk for brick... It seems progress bar is 0% so if it's failed before actual installation process, you'll survive.
[Vivo X80 Pro] lilddd:
what a gamble... hmmm...

device is really high temperature and keep updating

I'll wait for 2hours and after two hours

I'll cancel the update :(

Hello !

I was able to unlock BL. But do we know have a way to switch from OriginOS to FuntouchOS ?
[Vivo X80 Pro] PriMieon:
This would be great to know. Plan to perhaps get the Chinese one and reflash it. The global one is to expensive. I have a GP6P and it charges so slowly. I want to sell it and get this bad buy.

[Vivo X80 Pro] Ozzers:
Were you able to get Root on the device?
[Vivo X80 Pro] lilddd:
Yes. I rooted. and now i'm using magisk modules
[Vivo X80 Pro] adkana4310:
Do you Installed A13 Beta with recovery or with system update?
[Vivo X80 Pro] lilddd:
with system update

and A12 install with recovery.

if your phone build number is not W20

you can not install A13

there is no way
[Vivo X80 Pro] Ozzers:
Should the firmware update version be the same for CN?

I don't seem to find the exact 12.0.11.2 firmware for it on the developers' website, this is the one I found - PD2185_A_12.0.10.5.W10.V000L1-update-full.zip, and it's not W20 as well..

I also found more versions from unofficial websites - PD2185_A_12.0.11.8.W10.V000L1 Stock Recovery.zip - Still W10 and not 12.0.11.2
[Vivo X80 Pro] lilddd:
first. no. not same with CN

and the firmware is W10

so if your device is W10, you can flash.

update A13 first, and downgrade with recovery to A12
[Vivo X80 Pro] Ozzers:
I dont have the update for A13 from the built-in system update so I installed "PD2185_A_13.0.0.43-BWDATA.W10.V000L1-update-full_1655432757.zip" as a "local upgrade".

Now I want to downgrade to A12 but I'm not sure which version, should this one work? - PD2185_A_12.0.10.5.W10.V000L1-update-full.zip

Also found - PD2185_A_12.0.11.8.W10.V000L1_vivo_qcom_LA.1.0.r1-00372-STD.PROD-sm8450_split.tar.gz

Yes update to A13 mean that install with local update.

download that firmware and paste to your sd part. and then go to recovery mode, install A12 firm

hello sir.. how can I install in in recovery mode? I dont find the Local storage menu.. Its just a CLEAR DATA, CHECK SYSTEM and INSTALL SOFTWARE.. in install SOftware there is no LOCAL storage , there is a NETWORK update.. Im in A13 beta now I want to downgrade
[Vivo X80 Pro] lilddd:
put A12 rom in to your internal storage.

and reboot to recovery again.

if it's not work, just click the update file in settings-system update - local update

and try again to recovery
[Vivo X80 Pro] gerald1290:
when I tried the Local UPDATE it says Unofficial firmware.. or in the RECOVERY Mode.. theres no option to update via local storage.. Maybe I got the android 13 RECOVERY.. theres only 3 options

CLEAR DATA, CHECK SYSTEM and INSTALL SOFTWARE

while the install software its NETWORK SYSTEM UPDATE

No local storage
[Vivo X80 Pro] gerald1290:
its like this on my RECOVERY .. which in intsall software only NETWORK update to conected wifi.. and it is downloading my current android beta
[Vivo X80 Pro] gerald1290:
do i need to root it first sir? before I can perform downgrading?
[Vivo X80 Pro] lilddd:
no you don't have to.

if you don't have the storage update option is recover, try adb to boot to recovery

or not just fastboot ->recovery

try fastboot -> bootloader -> recovery
[Vivo X80 Pro] gerald1290:
I will try adb.. I really can find the option in the recovery

Do you have troubles with bokeh mode on camera or fingerprint sensor when you unlock the bootloader?
[Vivo X80 Pro] lilddd:
Now I have X70 pro+, X80 pro CN, X80 pro GLOBAL

all BL unlocked.

X70 pro+ has bokeh and fingerprint issues

after relock , fingerprint is working fine.

but bokeh, it didn't returm

but X80 pro has no issue at all :)

If you have problem after unlock X80 pro BL

just relock and unlock again

It will fix :)

and after root, X70 pro+ has network problems.

In KR, if the VoLTE is enabled, can not receive messege

but X80 pro has no problem even after root.

hope you have no problem :)

sorry about late answer :(

Hi,

I contacted giztop to check with them which version they have and asking about bootloader and here is the answer:

"hello,

Ok, that is fine, the phone comes as china version with google play installed, the bootloader comes unlocked.

thanks.

Please don't hesitate to contact us if you have any questions.

Thank you and regards.

Jessica

Does that mean that the bootloader is already unlocked if I buy it from giztop?

anyone here ever bought a phone on that website?
[Vivo X80 Pro] Dutch-Vivo:
I don't think the rep fully understood the question .... If it was able then everyone would have known about it by now and it would be sold anywhere with your choice of Rom.

It would have been trending on Twitter and Youtube and we would have seen dozen of posts here on this platform.

Hi,

I'm planning on getting a Chinese version x80 pro from giztop

Could anyone confirm the steps to unlock BL?

2) go to dev settings -> toggle OEM unlock

3) download and transfer Android 12 (PD2185_A_12.0.10.5-BWDATA.W10.V000L1-update-full.zip) and downgrade via fastboot

4) fastboot flashing unlock or do I need to follow https://xdaforums.com/t/vivo-x70-pro-bootloader-unlock-how-to-guide.4444989/

Hi Sir @lilddd

Thanks for the informativo.

So until now nobody could change in 80x pro (Cn version) of Origion OS to Funtouch OS (The Global Rom)?
[Vivo X80 Pro] Dutch-Vivo:
No, so far we have no knowledge of anybody doing that successfully (or willing to share).

As I stated before. The companies in Asia that sell these phones for export don't sell a Funtouch version either even though they get asked that question daily.

If it was possible you can bet that these companies would all be over it and boost sales. It's as simple as that.

I used the boot.img file from PD2185_A_12.0.10.5-BWDATA.W10.V000L1-update-full_1652273279.zip

phone is booting just fine

doing the setup in chinese was fun but ok

moving to installing Magisk

I ordered my phone from wonda and received a PD2185 still running version 12.0.10.5 so I didn't have to jump to A13 and then rollback. saved a lot of time on that
[Vivo X80 Pro] Washo4evr:

now running 12.0.13.5 with Magisk

[Vivo X80 Pro] Pervokur:
did you try to flash any full ota A12 for your device?
[Vivo X80 Pro] hamisgood:
Vivo fixed the rollback link so right now I am back to A12. However it seems like my security patch is too high and I am unable to unlock the bootloader with the June security patch. I am hoping someone still uploads the 1 April security patch and I can try rolling back to it in order to unlock the bootloader, but until then, I guess I'm stuck with locked bootloader unrooted.
[Vivo X80 Pro] Pervokur:
why do you think that you need special ota for rollback from A13? maybe there's no signature check and you can install any ota by editing metadata file like it was with earliest A12 on vivo phones

Can it working vivo Y85A 4/64 qualcomm devices?
[Vivo X80 Pro] Pervokur:
In theory it's possible, but needs further study.

After downloading 200GB of ota firmwares I have found vgc partition with uid 1000 (system) debuggable app com.vivo.vtool which can be flashed on any(?) qcom vivo/iqoo with dynamic partitions.

but If you will not be able to unlock bootloader then you will not be able to flash otas(most likely)

read this (I don't know if you can use any oem.zip)

https://xdaforums.com/t/how-to-become-uid-1000-system-vivo-y31-2021.4481887/

with uid 1000 you can change prop and some directories in /data, in theory it's possible to run commands as root by exploiting commands in .rc scripts

like this

on property:sys.cota_vgc.mount_to=* && property:sys.cota_vgc.mount_cota_img_path=*

mount ext4 loop@${sys.cota_vgc.mount_cota_img_path} ${sys.cota_vgc.mount_to} ro nodev noatime

maybe with setprop you can overlap original binaries and force to run your script with root privileges and flsh some partitions(like aboot.img [I don't know which partiotions is enough to boot with old fastboot])

[Vivo X80 Pro] Music&Art:
I have the boot img for this. I pulled it from the zip file of the 12.0.14.5 update. I'm not sure if it will work for you or if somehow it depends on the specific update you get on your phone but this is the one I have.

boot.img

[Vivo X80 Pro] Washo4evr:
Excellent :D

Thanks for sharing

will update now then
[Vivo X80 Pro] Music&Art:
Did it work okay?
[Vivo X80 Pro] Washo4evr:
it did, thanks

also, in order to save the update.zip file / interrupt the process, I found out that the easiest is actually to call adb reboot for instance after reaching 100%

here is a quick guide for keeping update files:

1) start downloading the update directly from settings -> software update

2) open up a terminal and be ready to adb reboot (bootloader or whatever)

3) when the progress reaches 100%, for a short period of time, it will display on screen "verifying the data integrity" (something like that)

4) at that time, run the command in the terminal

5) this will reboot the phone without installing the update

the update.zip will be available in /data/vivo-updater/com.bbk.updater/OTAPackage/
[Vivo X80 Pro] Pervokur:
you can prevent installation by erasing misc partition after reboot

also you can try to mount any dir after download start

mount /bin /data/vivo-updater/
[Vivo X80 Pro] Music&Art:
Honstly even simpler then all that the way I did it.

I turned off the smart upgrade and the automatically update over wifi options and watched it.

When it gets to 100 percent, it will pop up an option asking if you want to install it with a 9 second countdown.. You just click remind later.

Then open an app like Total Commander, go to file system root > data > vivo updater

Then you click on the folder there until you get into ota update

The zip will be in there

I then moved that over to my phones internal storage which is easy with total commander.

Opened the zip in total commander too since it won't install it from there and get the boot img file.

Voila.. Pretty simple. And you don't have to do any extra things.

You just have to watch when it gets to 100% on the update because it gives you 9 seconds and it will install if you don't put remind later.

Also if the file is not a 6gb ish file the boot img will only be a patch and those can't be used that I know of.
[Vivo X80 Pro] Givemobus:
You just patch boot.img file with magisk, then use on pc commands:

1. adb reboot bootloader

2. fastboot flash boot magisk_patched-25200_RsdJL.img

that's right?

Because for me i get stuck in fastboot mode after flashing patched boot.img, but i get unstuck when i flash non-patched boot.img from "Music&Art"
[Vivo X80 Pro] Music&Art:
Yes, that happened to me too. Try repatching it again and then try to flash the new repatched one.

I don't know why mine did the same. The second time I tried to flash the patched boot.img it seem to work.
[Vivo X80 Pro] lilddd:
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.
[Vivo X80 Pro] Pervokur:
not booting into fastboot?
[Vivo X80 Pro] lilddd:
after flashing

it stucks in Fastboot mode

after I go to main UI, It stucks in VIVO logo

if it fastboot loop, is there any option??
[Vivo X80 Pro] Pervokur:
well, you have unlocked BL and working fastboot, right?
[Vivo X80 Pro] lilddd:
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 :(
[Vivo X80 Pro] Pervokur:
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)
[Vivo X80 Pro] Pervokur:
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)
