Hey guys, I have my wifes z5 compact that was playing up and not charging right, so I ordered a new battery and USBport/ribbon and pulled it all apart to replace as I've done in the past to other phones, but when I got in there I have discovered the clip where the usb ribbon connects to the logicboard/motherboard is damaged (see attached image)
The device otherwise boots just fine and runs great with the new battery, I am however unable to charge it now.
I attempted in vein to find a replacement port to re-solder onto the board, but I can't find the model of the port or where to get it from. If it comes to the point where I need to get a new logic board I think I'll just get a new phone.
I do not really require USB access to the unit, but is there a way to jerry-rig some of the service points on the logic board to provide power to the phone, in which case I could just divert the USB plugs power channels to those points?

Hi,
I currently repair XDA Exec's for a client of mine who use them for their delivery drivers. They are constantly breaking the screens which are easy to fix, but more often than not they smash off the usb connector and leave it rattling around inside. This is not usually a big problem to fix unless the pads that the 5 pins are soldered to have been ripped off the board. I have found that even if I successfully replace the connector with a new one and solder the two outside pins (which are the gnd and 5v pins) the battery will not charge. The puzzling thing is, if I remove the battery, the red led comes on, presumably indicating power to the device. As soon as I connect the battery the led goes out and the unit boots up only to reveal that it is not charging. So I'm presuming two things:
1. There is some other electronic component damage in the unit caused when the connector broke (due to it being on the end of the charger cable at the time, if this is the case I will scrap the unit)
2. There is some feedback from the battery that the charger needs to continue with it's output and because I didn't reconnect the data pins it won't charge.
Does anyone know how the charging circuit works and what pin / connections are required for charging. I guess the same principle will apply to many PDA's & mobile phones.
Thanks
Rick

Forget that last post ok...
I'm starting to have real problems with my USB plug. At first it would drop charger plugs when it was on the wall, so I put it upside down. But now I can't connect to the PC all the time either. I have to jiggle the plug a bit or even breathe down in it (the moist makes the connection better). Has anybody else had that problem and fixed it in any way? I suppose the plug is soldered on in such a way that it has to go to a workshop, right?
i strongly suggest you to send it for repair or resolder the base of the connection(this is user servicable provided you have some soldering skills) so it doesnt wiggle. i'd probly even suggest to hotglue the plug but before you do so make sure the plug is sitted properly and it does sync
the same thing happened to me and with a bit of jiggle the plug broke off and now its permenently damaged(ie it will never sync via USB again) so far with self repair i only manage to make it charge
i got no idea how to reattach a 10pin mini USB plug to my board and some of the copper tracks looks damaged which means if i send it to the shops, its a $500 repair and a board swap
need help please people.
my phone hasnt been charging properly for a few days now, to get it charging now i have to get one of my missis hair bands and wrap it round my phone and then round the usb cable so it stays in , although today it doesnt want to charge at all now .
ive noticed that the connection in the phone is loose and you can move it round a litle bit,
now the bit i need help with , is do i take the phone apart and try to fix it.?. im thinking of doing this but unsure about taking phone apart ( dont think my phone is under warrenty anymore,) and im guessing the usb connection on the phone is fixed onto a board.
is it worth me trying that or should i just take it to a repair shop ?
take a dry toothbrush, give the usb port a good scrub. dirt often builds up in the bottom of the port and stops the usb plug pushing deep enough to get a good contact.
Have a good inspect of the usb port, bright light and magnifier is good, see if you can see buildup, or a bent connector, or somesuch.
Also look at the usb plug on the cable, its uncommon but not unknown for the metal outer enclosure to open slightly, and make for a weak contact.
Sometimes a cable simply doesn't fit well for no obvious reason, , i have a generic cheap ebay cable that will only work when angled up or down, like yours, but looks perfectly fine, and feels to fit the socket, while the HTC cable works perfectly, so i know its not the port.
If it all looks good, then chances are you have a dodgy connection from the usb port to the mainboard, which will get worse every time you wiggle and bend the cable to get it to work. In this case, you COULD try a repair, but there have been reports on here of some repair shops pronouncing it too fiddly to replace teh usb port, and a new mainboard would be the only other option.
edit - just reread your post and seen that you can wiggle the port. Broken solder, gotta be. Its not an easy solder, so if your a dab hand, then go for it, if not, see above.
Hi iainbp, heresandyboy had this same trouble in http://forum.xda-developers.com/showthread.php?t=903977 from post 16.
It looks tricky!
Just a thought though, I recently bought a cheap phone charger with multiple interchangeable heads for different phones. The microUSB one became difficult to charge with and it took me a while to realise that the metal bit at the end had detached from its plastic casing, and when I plugged it into the phone it just got pushed back into the casing. (got my money back)
Possible with yours?
Hi all!
I ask because I've got the "classic" phone will not recharge problem on my i9505.
However, I've ordered two boards from different places, both of which function worse than the original.
Original board: Phone will not charge, or thinks it is charging but the cable isn't plugged in- but buttons work. Switching phone off, shorting the battery pins, then inserting the USB cable and battery gets it to charge, however it will not know when you have removed the cable. I am using this board as the phone remains somewhat usable.
New Boards: Phone constantly shows "charging". capacitive buttons do not work.
Are any of you a dab hand at these repair jobs? I'm not new to phone repair (have had to repair most of my phones at least once) but this one doesn't seem to want to play ball.
Any thoughts? Am I doing something stupid? is there a specific board I need for my i9505?
My USB port died a few months ago - no data, no charge. I've been getting by with an extra battery and the external battery charger, but I'd really like to be able to transfer file between my computer and my phone faster than Kies does.
I watched a few videos on how to do the replacement and ordered the part. When I got it, though, I notice on the replacement board it says "rev 0.8" while mine says"rev 0.7." On visual inspection they look nearly identical, some different in the shape of the USB port. But I don't want to take a chance on frying anything.
Anyone have any idea if I can use this replacement or not.
Thanks in advance.
