USB no longer works - LG Revo
About a month ago, the USB connection on my revo just flat out stopped working. I've been through just about every forum post on the internet and am left without a solution. If there's anyone who knows of a solution to this problem, I implore you to share it with me! I'll worship you at this point
When I connect the phone to any number of computers (I've tried Win7, XP, Linux, and MacOS X) with any number of USB cords (of which I've tried 6 now), and the phone will generally just start charging but will not be recognized as a mass storage or connection device by any computer. I have tried every combination of mass storage mode, connection mode, with USB debugging turn on and turned off. I've also turned the "prompt me" option on and off to no avail. When USB debugging was turned on, my phone used to show the USB icon at the top after plugging it in. Now, it shows nothing.
ADB does not recognize the device at all either. Under Windows, I've tried both of these drivers from the LG site:
LG VZW United WHQL v2.5.2.exe
These have no affect. I've installed and reinstalled and rebooted too many times to count.
Note: this phone IS rooted but I have not removed any software from it. I have, however, used the factory reset just to see if that would make it work.
In short, I've ruled out configuration issues, USB cord issues, driver issues, specific computer issues, and (with the factory reset) some type of funky software issue in android. The next and last thing I am thinking about trying will be installing a custom rom. Unfortunately, I'm going to have to find a way to do this without connecting it to a computer. I believe a boot loader can be installed directly onto the device but I haven't dug deep into the directions for how to do this yet.
My question, then, is could using a custom rom possibly solve the issue or am I just wasting my time by installing one? Also, is there anything else - anything at all that could possibly cause this issue or is my phone just toast?
Sorry for the long post. I wanted to get the point across that I've done all of the usual stuff. I'm far beyond that point. Thanks to anyone with answers/suggestions/advice!
