Hi,
Nokia has changed life timer read, reset, edit field from PM latest rapu phones.
In latest rapu phones life timer is stored in PM '382,1' if you want reset - use below PM to reset it to 00:00:00 - write as PM file!
@Dzirt
Now even inf-BEST do not supports this ;o) software says 'life timer is already reset or '0' :-)
PS: thx @Moosani for test phone.
PS:2 This should work also in Nokia N8 or other latest phones.
BR, Ali
