write new SN from the battery with sigma
OR if it is new OEM battery, never paired with other board, should work w/o any problem

Huawei P30 pro and all P40 models.
1. Switch on the cell phone with the old original battery and leave it connected to the charging cable.
2. Change the new battery in the switched on and connected charging cable.
3. wait until the mobile phone has charged to 100%.
NOTICE! Be sure to wait until 100% has been reached and then leave it on the charging cable for 5 minutes longer to be on the safe side.
The battery can sometimes remain at a % level when charging, DO NOT unplug before 100% ,
a detected error from the battery is corrected directly by the mobile phone and the battery is recognized.

PS: keep the old battery, if at some point the battery has to be put back in the phone, then you have to do it again. That's why the battery isn't thrown away.

Even brand new original batteries can sometimes cause reboot upon change.
(i've had such case on p30pro)
And, yes - if you have active tools, reprogram, if not - battery swapping trick works, i've personally test.
Zero problems after such swap.

Hi,
Dear forum members I have seen the video about battery replacement of normal huawei android phone but my view is that normal huawei phone battery and your smart chip based phone battery are mostly different. If you have an old battery sticker with a serial key, set the serial key with professional tools and hopefully your Rebooting problem will be completely solved.

absolute trash phones, like the rest of their "companions" - xiaomi, oppo, vivo, zte, etc.

at least, after US ban on android, nobody is buying that crap anymore

p.s. chinese trash phones with "battery protection", it's like their chinese neighbours cant make the same battery with same chip ? lol.
at least i'm happy not to see that trash brand anymore, like sony disappeared in this region
