I have a spare 2G logicboard lying around which im pretty sure works...i want to test that it works in order to sell it...

Can i remove a different logicboard from the comm board while the battery is still attached without anything short circuiting or burning anything...??

Any recommendations welcome! Thanks

Any 2G logic board (4,8 or 16GB) board is compatible with any 2G comm board. This is the best way to test a logic board.

yeah but will the comm board or logic board burn out because the battery is still connected?? i dont want to have to go through the trouble of desoldering and soldering again...

I've done this many times in the past when I worked on 2G iPhones. I never had an issue. If you want to be 100% safe and have good soldering skills, then remove the battery first. No harm in that. Personally, I found it to be a huge hassle to desolder the battery unless I absolutely had to.

cool thanks a lot...i dont mind soldering but if i dont have to, than so be it..

you dont want to do that my friend. yes we've all successfully moved the comm board with battery still attached one or the other time before but, i've managed to kill two comm boards in this manner.
desoldering just the ground battery cable(black) wont require quantum physics and would save you a lot of hassles as it shuts power of the board completely.

nb when you do desolder, use tape tape to hold the wire against the body of the battery so it dont touch anywhere as yo make your change.


i hope i aint too late
goodluck man!

Just for safe sake, follow ndagi recommendation.
