Hey,
I'm having trouble with my 9790, the majority of the time the phone can't get past the boot screen and reboots but the odd time it manages to boot up fully but after a few minutes it turns off again. I noticed what looks like red ink on the pins that connect to the battery, which makes me think it might have some water damage or a damaged battery. If anyone else has any other ideas or have any possible solutions that would be great.
Thanks.
