Install anyway?
And when pressing yes i get
Error applying update: 51 (ErrorCode::kPayloadTimestampError)
ERROR: recovery: Error in /sideload/package.zip (status 51)
do you know how to fix this?
(for steps i took. i flashed
boot.img
dtbo.img
vbmeta.img
vendor_boot.img
recovery.img
from https://xdaforums.com/t/rom-16-unofficial-beta-evolution-x-11-2.4760259/ and then booted into recovery and tried sideloading the unoffical build)
I assume you are already on A16? This is a A15 build
if i remember correctly i had firmware version 15.0.0.860 so that means android 15 right
Which ROM did you had initially?
I had the original stock one plus oxygenOS. Then tested stuff like camera calling SMS and updated to the latest update. Afterwards i tried the above steps to flash e/OS, that is:
Unlock bootloader
Boot into fastboot
fastboot flash boot boot.ima
fastboot flash dtbo dtbo.img
fastboot flash vbmeta vbmeta.img
fastboot flash vendor_boot vendor_boot.img
fastboot flash recovery recovery.img
Where the above files came from the evolution link you provided.
Then i tried:
adb sideload e-3.1.4-a15-20250921-UNOFFICIAL-dodge.zip
Which gave:
This package will downgrade your system
Install anyway?
And when pressing yes i get:
Error applying update: 51 (ErrorCode::kPayloadTimestampError)
ERROR: recovery: Error in /sideload/package.zip (status 51)

Since my abl.img was still original i used the following to unbrick my phone:

I tested with EU .860 firmware version and followed the .bat script provided in the forum and in the end chose to format the data.
