Dodgy...

Thought this forum was about helping people if you could, not charging for the information. If I know anything that will help someone on here, I'll pass it on. If I physically fix someone's equipment in my workshop, then I charge.

The 3GS power IC image is terrible and the explanation in pidgin English is too poor to follow, which is odd for someone who apparently worked in league with the very person who designed the iPhone. I think you are stating that the voltage supplied by the USB cable goes to the two MOSFETs in the image (not fuzzes - is that an attempt at fuse? You do know they're MOSFETs and not fuses?! - or whatever you call them), and then to the 338S0768 power management IC, which outputs the voltage to the inductor (or coil, if you prefer) and onwards to the battery. My concern with the 'fix' of directly connecting the unprotected USB power line to the battery is that there is no voltage or current control of the feed to the battery or charge monitoring, and li-ion batteries are known to be fussy about that kind of thing... The schematic does state the USB charging voltage to the 2 MOSFETs is unprotected.

Your right chapster. Only a idiot will do this to connect this directly without any protection. The phone can burn down and your house too.

[/QUO

dont forget this tip work 100% and its dot dangerous
i know thats little bit dangerous but its working and sorry to say you know about hardware but you tell me how much people know about hardware n hows they hardware skill ?
we all know way we sit on forum . 2ndly 3gs power chip is easy to change for any one ? not its really dangerous after removing power chip u phone is totally in sleep mood you must past power chip perfectly if u cant or if u damage any single point than you loss your cell phone thats y ill post this solution for our juniors they cant change power chip now i am sending complete solution before i am sending only tip

Contradiction in terms springs to mind. It's more than a bit dangerous if the li-ion cell gets hot enough to cause a fire from overcharging...

Anyway, I'm surprised you haven't tried to charge people for this 'tip'.

Are you really an electronics repair specialist? Do you know what causes things like the 1611 error? I'm not sure about you at all.

3G is really slow. Does everything but 4-5 times slower than should. Been updated/downgraded but same with any software-baseband combo. Anybody has an idea?

Hi,
i cleaned antenna switch and SKY77340 components with alcohol,now i get no service all time.before i had no signal/1-2 bars max,and checked antenna trails on motherboard so that was my only solution.Would re-heat those two components help,and what temperature i must use?Thanks!

hi guys need some help. i have a 3g here which has a very weak signal, it will connect to the wifi if it is up close to the router (the router is fine as other devices use it) but once you move about 10 ft away it loses the connection, even when you are up close to the router it doesnt seem to actually be connected even though it says it is, as the pages wont load

thanks in advance for any help

regards

Darren

Wifi Antenna is Ok? Wifi connector on PCB is not damaged? No screw drilled through the Wifi cable? (yes.. i have seen this..)
If you have a 16Gb model (never seen a 8Gb model with wifi probs) maybe the Wifi IC is a little bit damaged, but when you are close to the router, you can open websites?
Check this..

hi thanks for the reply, the wifi antenna is ok , the cable is fine, the connector on the pcb is good, i have re-soldered the connection, its an 8gb and when i stand next to the router it wont open page at all, maybe when i first go over to it, it may open google but thats it nothing else

thank you
