[Commboard & Battery problems] wtf?

[KoSoVaR]

1 iPhone doesn't boot
2 iPhones don't get reception (wifi, gsm, bt, etc)

I plugged that one that doesn't turn on in to a wall outlet, and it turned on.. unplugged the cable, it shut off.

As for the other two phones, I've fucking tried everything.. jesus christ. I can't get anything to work, and I don't know how I would have fried to comm board if I didn't put any needles on it..

any suggestions or tips? :)

Suggestions(at your own risk):

1. Take the commboard from the phone that does not boot and put it in one of the 2 iphones with no reception, see what happens.

2. Take the logic board from one of the phones that have no reception and put it in the iphone that deosn't boot.

3. Take the battery from one of the iphones with no reception and put it in the phone that does not boot.

See what happens, maybe something valuable will come up. Don't do too much swapping though, or you might end up with 3 phones that do not boot :p

You have damaged the protection circuit. Soldering a lead will from the battery to pass the circuit will help. Look in here for a picture!

has anyone tried this succesfully?

I have :D
Right now I have 3 phones that do not boot. When I make that jumper with the testpoint tool that I use for hw unlocking, any one of them starts up, battery level is displayed correctly, charging is fine, etc. However, if I disconnect the testpoint, the phone dies. As the guy that suggested this method -Francis- said, it seems that this circuit easily breaks and it needs to be re-created. I will take the commboards to a friend of mine that is good with soldering sometime next week and get back to you.
Good luck!
