bootloader problem ?

I have a mda compact which when the battery is inserted reads "serial v1:2"
nothing else happens unless the usb cable is conected then the screen changes to "usb 1.2". and the pc says unidentifiable device present and dosen't sync.
any help apriciated ! mda is other wise in as new condition.
The red led iluminating breifly when the usb is conected.
UPDATE
The mda compact was showing no indication of charging with just a red indicator from the led for 2seconds when the charger was pluged in.
When conected to the PC the screen changed from serial to usb, how ever would disconect after a while and was unable to conect to the mda via the usb as not recognised.
After leaving to charge for a night, with no indication of charging, the MDA did not then self disconect from the PC and so the battery must have been flat !
Was then able to down load the "1.13 T-Mobile rom" on to it from the upgrading link and now all is well.
Still don't know why it was stuck in bootloader mode ?

What phone model is this?

Anyone?
Also would HTC Desire charger work with it? (the sticks looks same - microUSB, but looks like the phone is not charging)
Also if the phone is dead, is there any way i can check if the battery/screen or whatever else is faulty?
When i connect it under Windows with USB cable, it says that the device cannot be recognized and the drivers cannot be installed.
When connected with USB, i did hold the power button to turn it on but it doesnt start and the phone keeps vibrating continuusly.
Look on the back, or inside, even under battery, for more information.
I already know it's Samsung Galaxy Mini II, homever i have issues turning it on.
All microusb chargers are the same except for amperage. Try all you have. This phone is probably terminally damaged, but try a new battery if possible.
It's really strange (the phone was little wet) homever, sometimes it's starting just fine and sometimes wont turn on at all.
I have removed battery and put it to the bowl with a rice for a night and will see if that helps.
My "dampness" recovery is to disassemble and put phone/tab/laptop in in very low oven ie 125-135 degrees F for several hours. You may have ti turn oven on & off manually to get that low temperature. Your mileage may vary.
OK so basically the phone is in following state:
It's charging fine, homever the biggest problem atm is i cannot get the usb mass storage to work.
I'm connecting it to the PC and the phone is detecting it as AC charger not USB - PC is not even trying to install any drivers.
PC is not detecting the phone at all (phone is detecting that its being connected, the button backlights are lighting up)
I got no dropdown in the phone to select charging, mass storage etc. (when i do it in settings/communication/usb settings it keeps saying to connect the usb cable, but the phone is charging so its connected just fine)
When i was connecting it for the first time windows tried to install drivers but failed, also it was constantly disconnecting the phone from usb cable (now its fine it seems)
When i connect it using "Kies Air" it's working homever i still dont see the SD Card in "My Computer" for example.
What a mess, anyway any idea how to get the USB working again?
Try different cable, and/or different PC.
I ordered new usb cable, homever i doubt it's the problem as the phone is recognizing connection and also it's charging fine.

Sony Xperia L (C2105) charging problem

I will tell the whole history just in case, it might be relevant.
It started with battery problems, it was charging at a very slow rate (4-5 hours) and it was lasting 1 hour top. The camera was the cuplrit, it wasn't working at all and by disabling the camera app the phone worked fine for a week.
Suddenly stopped charging now.
When the phone is on it doesn't recognize the charger not even the computer, no bottom led. The computer doesn't recognize the phone either.
When the phone is off, if i connect the charger, the bottom led turns red for a second, SONY logo appears, battery appears for another second and reboots... infinitely.
I thought that the USB connector was the problem but i can connect it to my laptop in fastboot mode and flashmode, the phone is recognized in both modes, i even "repaired" the phone with Sony PC Companion and i'm having the same problems like before: no camera and no charging.
I don't think it is a firmware problem, i've re-flashed two stock firmwares from XPERIA Firmware website and no success.
Any ideas? Thanks in advance!
Dude I have the exact same problem. Would like to find out a solution
Could be a hardware problem.

i used power bank to charge my phone,Suddenly stopped charging now.
When the phone is on it doesn't recognize the charger not even the computer, no bottom led. The computer doesn't recognize the phone either.
It is charging properly with power bank always but not with charger and computer with usb. if i connect the charger, the bottom led turns red for a second, SONY logo appears, battery appears for another second and reboots... infinitely.
I thought that the USB connector was the problem but i can connect it to my laptop in fastboot mode and flash mode, the phone is recognized in both modes, i even "repaired" the phone with Sony PC Companion and i'm facing the same problem still.
Any ideas? Thanks in advance!

[Completed] Charging Problems!

The problem started a few days after flashingMegbyte Kernel r_4 on top of RR 5.5.8 on my 1.5 year old Moto X.
Here's what i did and what happened after that-:
-Kernel Auditor->Battery-> Enabled "Fast Charging over USB"->Apply on boot (Wasn't available in stock Kernel)
- Worked fine for a day or so
-Phone starts to misbehave. I plugged the usb cable, but it used to take a few seconds for actually start charging
-The ROM becomes unstable
-I switched off my phone and plugged the charger. The motorola "Bootloader Unlocked" warning shows up. It shows that big battery indicator, but then switches off automatically.The process repeats and this keeps happening until i don't unplug the charger or force boot.
-Meanwhile, when my phone is turned on, and i plug in the charger, sometimes it shows the charging indication in statues bar, but when i got Settings-> Battery, it shows that it isn't charging.(Can't post any link to screenshot yet ._.)
-Sometimes, when i plugged in the charger, the phone didn't show any indication or charged
(MY CABLE AND CHARGER IS COMPLETELY FINE. USED ON OTHER PHONES)
-I thought it was the ROM's fault, so i flashed CM 12.1
-I am on CM now and still facing the problem
-I've tried callibrating the battery, no luck!
-My computer detects that theres a device when my phone is connected via USB, but cant detect what device it is. I've downloaded Motorola USB drivers. The computer did detect which device i was using but only for a minute or so.
I am in need of help and your help would be appreciated! :]
