K810i restart sometime

[riders4sia]

first of all, i'd like to thank this TopSony forums. i always like TopSony from the day I joined. I like this job, really. so my problems, my phone's been 1 year old but since from the day i brought, it get restarted sometime and i don't mind about that at the first place, i had already upgrade it to R8BA024 CID52 with lots of patch and some elfs, i had been using in this condition for a year.
The big question is will it solve my problem if i upgrade the EROM to K810_RED_CID52_R3B025_EROM-FOTA_2007-07-24_14? the current version is R3A022.
Thanks in advance.

Maybe restarts because you have old library.

i have upgrade the library too, it start restarting itself before doing anything, i.e. when it was in brand new condition

Maybe battery connectors are dirty or not good pushing.

you meant like it's old? here, restart means not like off and on again, the screen goes blank for a second and then off, after 3 or 5 secs the screen lights up and search for network and work
i hope philzfog can help me
