Hi all..
this is a general question really about the issue with Micro USB cables and the connector's ability to stay connected.
I know it isn't my phone as when i buy a fresh cable it clicks in nicely.
Does anyone recommend a decent cable where the connector stays connected after more than a few weeks of use?
I've obviously used Stock HTC, but also PortaPow (power only), Blackberry cables, Nokia Cables, Samsung with varying success.
Thanks
Since I do not have the original one for this phone I tried my Nexus 7's USB cable and its rather loose, I don't think I can flash a ROM with it due to the chance that it comes off during flash(which it does from slight movement when connected as MTP; its not coming off per se, but it does get disconnected).
But why does it? MicroUSB should be identical, or is the DHD USB port broken?
All microUSb cable are the same.
You can try to clean usb port.
You can find plenty help page on internet with: how to clean microUSB.
It doesn't matter for witch phone. All are the same.
So my USB Port is broken. I use this phone as my back up. Also just swap out batteries. However I was wondering how easy/hard would it be to replace the USB Port. Has any else looked into doing this?
I had the phone for like 2 months now,anyways the phone stops charging if i move the cable slightly.I noted that the second cooper pin from the micro usb is missing of pushed idk.It's charging but its annoying when I use it while charging.I tried different cables but they don't work or chargr slowly.Do you think I can fix it with a needle or something?
I'm not able to get to the bootloader screen because the front usb port is not functioning on my unit. Has anyone been able to use one of the USB ports on the back to get to ADB and/or get to the bootloader? Is this a known issue with a workaround? I've done quite a bit of searching and have not turned up any solutions. Considering what is involved in shipping this back, I'd much rather figure something out. Thanks in advance for any help!
Edit: I should mention that I have used the adbon password and it does acknowledge that adb has been enabled. Just nothing seems to work on the front port. When I connect my Linux machine and run lsusb nothing shows for the unit. I have considered buying or making a USB-A to USB-A cable to connect my computer to one of the back USB ports, but I'm concerned about how these back USB ports are designed. Is it as simple as a built-in OTG cable? If so I'm probably fine. If it is more like a computer's USB port I could damage my laptop, my headunit, or both. I'd really like to hear if anyone else has had to deal with this. Unfortunately I haven't verified if the front USB will charge a phone. This is my next step.

My front USB also doesn't work. I even got mini to standard USB cable with unit, but plugging flash drive into it doesn't produce any reslt.
I also plugged extension cable to one of back USB ports and tried it (plugibg same USB flash) but it doesn't work either.
So I'm also confused.
Does that mean you are still running the stock ROM? I have been hesitant to install the custom ROM because they say you must be able to get into the bootloader even though I couldn't find a step in the process that required it.
Regarding the USB ports not working at all, you may find that you need to use a powered USB hub. I've seen reports of USB devices acting up due to the low power. This is one of the reasons I thought it might be safe to use the rear ports with my computer. (My first real test is going to be mangling a male-to-male USB cable so only the data lines are connected to see if I can get those rear USB ports to talk to the computer. I figure that way there is no chance of frying any circuits.. Each side already has its own power and I don't believe any signaling is sent via the power pins.)
On my unit (MTCB-KGL-V2.80), I have used a T-Mobile USB broadband modem successfully on the rear port, so I know rear ports are live. I did take it apart to see if something was obviously wrong with the front port, but nothing jumped out at me.
So I have a bit more information on my headunit. BTW, I have the BMW E46 model with MCU MTCB-KGL-V2.80.
On my system, both the front USB port and the rear 3G USB port are wired as device ports connected to an AU6258 USB controller (http://www.sunnyqi.com/upLoad/product/month_1403/201403162331285643.pdf). I don't remember exactly which USB ports they are connected to, but I believe the 3G port is connected to port 2 (pins 6 & 7) and the front USB port is connected to either ports 3 or 4 (pins 9 & 10 or 11 & 12 respectively). Nothing is connected to port 1 or to the upstream port. The other rear USB port is wired directly to the MTC_RK3188 board.
All three ports are wired with only four pins, so I'm concerned that none of them could work with the computer. The USB controller doesn't have USB ID pins, so does that mean that the 4 downstream ports are OTG and the upstream port is for a computer? Unfortunately I don't know the hardware side.

No I flashed Malaysk ROM from GPS SD card. No problems. Just follow instruction. I had luck that I didn't need to recover from USB.
Did you tried with USB powered hub? I don't have one to try it myself.

I checked on my Linux workstation with
Code:
lsusb |wc -l
plugging and unplugging all three USB cables and the number did not change. BTW where did you use the "adbon" command? The only place that I could even try was at Settings > Factory Settings. Regards Flint
