a water damaged mainboard is ok for testing?

[huzein]

hi all, i want to improve my soldering level, but before i take hardbricked phones like i9100 with very small pins, i want to try and learn first with test mainboards. so i am wondering if i could get a connection to bootloader section of mainboard even if mainboard is water damaged?! because prices for water damaged mainboards are very low.

hope somebody can answer me. thanks and best regards

Since all new models are that small except for the T989 i belive it is worth it. But if you get a water damaged board, be sure you dont brick the eMMC chip or even if possible get a board with good eMMC chip, this way you will get a spare one if you get one harddeadbrick eMMC chip. I am testing in new ways of getting this done easly.... sort of....

Why dont you just buy the jigs? That will help you a lot more, and are cheaper than buying water damaged boards for testing...

jigs are an alternative but can never the replace the solder option. because it takes time to make the jigs. to be able to solder is very important, for sure should be the first choice and then to use or to buy the jigs.

i repaired now successfully my first i9100 and for me personally to solder wires is easier to solder the molex to use the jig.

then you are not up to date, because for the adapter for samsung i9100 you first need to solder molex on pcb and then you can use adapter.

You're right, i wasnt up to date, since i didnt know the molex thing. Are there any other models which require molex or similar?

yes, now almost all samsung models have or you must solder the molex connector if you want to use jigs. But for me it's easy to solder wires then molex. It will be easy if you need use riff box more then one time.
Anybody know where can i find the molex connector but not at multicom?

[huzein]

i think there are really less companies / webshops which offers such molex. Maybe you can find some from china, but i ordered already many times from multi-com, and the delivery was always very fast, i recommend to buy from multi-com.

for every phone model, which has so small pads like i9100, first needs molex soldered on pcb. For me personally is easier to solder wires directly to the pads too, instead of soldering the molex first to be able to use the adapter.

but for example for i9000 multi-com has a very good adapter, very stable. for this model i use adapter, goes very fast, saves times, and for customer the warranty if he had still.

You dont need soldering if your using jig and flat ribbon cable with connectors on both side, one for box and other end for jig.

we are talking about the molex which must be soldered on the pcb and not about this what you are talking about..

yes, but multi- com ask HUGE fee for shipping. It must be some china companies for molex connector.

multi-com send also for 6 euro. you dont have to pick for example DHL for about 35euro.
