USB port does not work, any way to fix or root?

[TripFlex]

So for some reason my USB has stopped working and i can no longer connect to a computer or charge the phone.

I've already purchased another phone so i'm trying to repair this one to use as a backup.

I took the phone apart and the USB port looks to be in tact without any problems, does not appear to have any loose connections or broken connectors.

I did find what looks like maybe some type of corrosion that may have seeped under the tape and bridged two connections on the board.

The phone works perfectly fine except for the USB port, as long as i use a charged battery the phone does everything is has been able to since i purchased it the day the EVOs came out.

So my question is, does anybody know a way to root with hboot 2.16 without using USB? The only method I found to root was the most recently beta released version located at http://revolutionary.io/ which requires a connection to the computer.

I found a possible fix for usb not working and in order to try it out i need to have a rooted phone.

Does anybody have any type of schematics for the EVO? Showing pin outs, etc?

Here's a picture of the section i'm most concerned about, so maybe i could possibly bridge the connection if for some reason it was damaged:

I'm pretty good with electronics and have no problem soldering connections, i do it all the time with traffic signal electronics. Just wondering if someone knows where a schematic or something would be?

Any ideas guys?

Please don't waste a post by telling me to file insurance claim, I did that already and already have a new phone, this phone i want to try and get working so i can have it as a backup in case something happens with my current phone.

Thanks for all the help in advance!

Oddest thing! I came to the forum to post about the same problem. I just noticed that I cannot mount my phone to my computer anymore. I did not change ROMs or anything. It was working before.

It will charge but when I plug it in my computer says an unrecognized device is found and that's it. It won't install it and just gives me an error on the PC. This occurs on my desktop, netbook and work computer where I used to be able to mount.

Not sure about any schematics or is any exists for this certain occasion but with the problem you have there I'd say if your experienced enough you best getting brand new charger port from ebay rather then fixing that busted one. you can get a good OEM charger port for $5 on ebay

To everyone that says they can charge but no data connections via usb. We busted our ports somehow guys and girls... It's not aofwatre. Bootloading problem etc.. It's hardware. Known issue if I recall as well.

Also you should try to sand the corrosion with a fine grit if you can. Or maybe it was bridged and you fried something. Have you seen any burnt parts on the boars?

Is there an official post regarding this "known issue"???

Or is there a DIY fix for this? It is quite annoying to transfer files on and off my MicroSD without a USB connection.

 

[GuestX0011]

No but I have heard people taking their phones in due to USB port issues and said that the people said it was a known issue. As I recall if you look into it you should find that there is alot of problems wiht people and USB port issues.

Yeah i still haven't been able to figure it out, got busy with work and didn't have time to mess with it until just now.

I'm going to order a new usb port and solder it on and see if that works.

I will update this thread with my results, should be in about a week.
