ok, the connector is broken.
I disassembled cover parts,
fixed connector,
I'm sure there is 5V inside (the connector inside I measure by voltagemeter) when I plug-in the external charger. The connector has 3 pins for GND and 3 pins for 5V and I'm sure there is volatage inside.
But the battery is not charging. O/S say the battery status as remained, but do to charge.
how to fix? what next to check?
crying:
You could check to see if the protection fuse has blown, if so you can bridge the circuit, if you search for charging or charge on the forum you will find pictures and methods.
the protection fuse just beside the battery? under small piece of white scotch tape?
fixed
thanks for suggestion.
yes, it was broken micro fuse, the one right beside the connector pins on motherboard.
Glad to be of assistance, hope its all ok now. 8)

Hi Jgui, could you tell me how you managed to repair borken connector at th bottom??
I search for a repair shop for my MDAII or th way to do it myself...
thanks a lot for your answer

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 have a problem with charging and i guess also USB connection.
When i plug in a usb cord to the phone i have to hold the cord upwards for the phone to recognize its there and start charging.
I guess the connector on the phone is somehow damaged but i cant see any damage to it.
Is there a quick solution for this or can I replace the connector?
Maybe you have torn off your mikrousb connector from the board. If you have good soldering skills, then you could try to disassemble the phone, and re-solder the connectors contacts. If you have no such skills, then better take it to a repair center to do it for you. I suggest not to charge your phone before you repair it, because you can damage the charging circiut, or force the charging socket to come loose, and damage the circuit board.

Thanks mate, I've got a good friend which is very skilled in soldering, i'll try to dissamble the phone and take it to him.
Is there any good dissamble guides for the HD2?

Thanks again thats perfect..
I fried my charging port socket (don't ask -- coffee, I think). It smelled burned and the charger tip would get hot in the port. I bought a new charging port panel and properly installed it with the protective film removed from the bottom and carefully connected the ribbon cable. The phone will not accept input through the charging port micro USB, but it will charge on a wireless charger. Could I have fried the connector at the battery through which the plug-in power goes? Is there a separate circuit that inputs current from the wireless charger? Could that explain why changing the charging port circuit panel did not fix the problem? Should I buy a new battery and try that? Diagnostic help would be appreciated.
Hi folks. A friend gave me his phone after he dropped it in water, and then tried to fix it himself.
The connector on the motherboard has been pried, so half of its cover is missing and some pins are tangled up inside.
I'm guessing about 4 pins are mucked up; the rest are fine. But the phone will not power on..
I'll try to include some pictures.. Any ideas how to proceed? I thought about soldering tiny connections from the MB to the ribbon connector.
Replacing the connector seems equally difficult due to the number of unsoldering/soldering to do..
Any ideas what to do?
PS: Forum attachment limit is silly; I'll link to external images on my server instead..
Check the pins of the connector that has an "MB" label on it:

Hi folks,
I'm trying to fix my old Nubia with a broken USB port by bypassing the port.
Since it's soldered to the motherboard, it's almost impossible to solder right on the usb pins.
But I've noticed testpoints, and found the VCC one, on which I soldered a wire. another being soldered to the outside of the port for grounding.
I thought I would be able to charge it that way, but it's not showing any signs of life (with or without the battery)
So I have 2 questions:
-can I charge through the testpoints ?
-do I need to send a signal to the ID pin ? (I guess not, I opened up a charge only cable and it had only 2 wires)
Pic of the connector
I tried charging it with a lab psu and an Aukey Quickcharge 2 charger
Thanks for your help
