Reboots every 3 mins after battery replacement

I did a refurbishment on my 3GS and replaced battery, front panel kit and the rear case.

The phone boots fine, everything works, but after 3 mins the phone suddenly reboots. Also the battery seems not to be charging.

I reopened and remounted everything and made sure that all connectors are in place, all skrews are straight and locked and so forth.

I also weared an anti-static wristlet during repairs.

Any ideas? Is there a way to run kind of logic board tests for an iphone?

dieter this is perhaps one of the most common questions on ifixit for iphones.. there are plenty of similar answers too, so have a browse under the photo of the phone at the answers. Basically your phone isn't recognising the new hardware. If you put your old battery back in then all should be fine again. If you try and restore in its current state then you'll most likely get error 29. The solution is to request an exchange from iFixit. It is a bit of pot luck whether your phone will accept the new battery as not all apn actually mean anything on OEM batteries these days. good luck. if that doesn't solve the problem let us know.

Well, I bought the replacement battery from ifixit.com, so I assumed the replacement parts they sell would work.

Tonight I´ll replace the battery with the old one and see what happens.

Thanks for the answer.
