downgraded p40 pro using hiproxy now stuck on rebooting from homescreen every 20 seconds.
i want to upgrade to another firmware but how would it be possible if the download/update doesnt finish and disconnects.

I suspect you flashed a wrong LGRPx base for your device variant.

i guess so i lost my imei but still can login and see my homescreen and open close apps like normal its just doesnt last more than 20 seconds and reboots again. how i can recover from this? planned on installing another firmware but not possible because when downloading a new firmware it disconnects when it reboots.

Factory reset and Star fresh. It will solve many problems.

which means Star fresh ?
wipe cache + factory reset and still the same error

Yes it is. From my point of view service firmware do the job. I have personally contacted service engineer of Huawei service center. If in case service firmware not flash properly that means one of partition is damaged and we must replace main board which was done by me on my P30 Pro. Don't loose hope last option if you are in warranty period then go to service center because Huawei devices are easily brick.:crying:

Thanks 👍

I don't think that the motherboard would have to be changed immediately, it is necessary to try all the possibilities, try the flash via the already mentioned usb key

i took it to Huawei service center and they changed the motherboard (under warranty) in 6 hours and returned my P40 pro. .. this is the only solution if you have installed wrong OS via Hisuit proxy ..

At least it turned out well that they fixed it as a guarantee
