Answer to: Replaced Battery, Constantly Reboots and unchanging battery percentI found the cause... Magnified inspection of the motherboard revealed two resistors missing from the bottom right hand side of the battery connector next to the standoff hole. (look just right of the green indicator line in this photo at the bottom of the battery connector… on mine the two resistors closest to the standoff hole are gone http://img829.imageshack.us/img829/5991/... ). Each time you shut the phone off then power back up it reboots every three minutes for 6 power cycles then operates normally aside from no accurate battery percentage. It would seem that I must have hit them with the standoff itself during removal or replacement? I would guess that if anyone else has this issue to look at the condition of this group of resistors very closely and perhaps a little love touch from a .5mm solder gun on each end of the resistors or forced air in this group of resistors "MAY" reflow the resistors to the board
Answer to: Replaced Battery, Constantly Reboots and unchanging battery percentI have one in my shop right now doing the same thing… Battery percentage does not change and the phone reboots constantly with the original battery and with a new one. Originally the phone came in with a bad power button so we changed the Power/Mute Lock/Volume button flex ribbon … which appears to have caused the new issues. May try another ribbon just to eliminate that as the cause but Ive personally repaired hundreds of 5 series with bad power buttons and never had this issue afterwards. WEIRD!!! Will post results.
