Pocophone Error 7 recovery / Vendor problem cannot install any rom

[jackaros]

Hi i have a problem with my poco f1
Status : UBL , NO OS , Orangefox recovery
Tried : flashing many roms and changed from twrp to orangefox but the problem persists. While trying to install the roms i wiped everything before.
Problem : Whenever i try installing a custom rom i get an error 7 message that says : xiaomi.verify_vendor() failed to read current vendor UTC build date: -2
I am not able to flash any custom rom and when i try i get this error.

The problem occurred when i tried to boot on my installed rom from multirom recovery. I had backed up everything but when i restore the backup (except the multiRom recovery) the phone is stuck on the pocophone logo.

If you need any more info i can provide please ask for it.

try clean flashing global stable fastboot rom using mi flash tool then flash twrp and flash any rom you want

I will try this method first due to the smaller download size. I hope it works so i do not have to flash the stock rom again and go though the whole process.

It worked. I am now flashing a custom rom. My question is why did this happen ?

BRO WHENEVER you are trying to flash new rom be on latest vendor , firmware and vendor can be found on leanage os xda page 1 , updated rom requires latest vendor

I think you came from MIUI10.2.x
since, miui10 on android9, Xiaomi has started using MODIFIED version of VENDOR image*
so when you flash custom rom which works on standard vendor image, it gives your either error7 or hangs on splash screen



*android has following partitions /boot /recovery /system, /data, /internalstorage /persist /OEM
oem or VENDOR partition translates android
using modified oem (vendor) image in android 9, its xiaomi's attempt for speedy android updates (CGI) (treble)

Just a follow up question..
So what will happen to my phone.. if its on miui 10.2.3.0 then i flashed the latest vendor img?? Will it cause bootloop?? Will it have a better performance?? Will it make games much smoother???

miui10.2.x has its own modified vendor image,
to comeback on standard image, you must flash the image (which you did)
