I am having the problem very similar to this post: http://forum.xda-developers.com/showthread.php?t=1317916&highlight=USB+does+-work
Though the poster has abandoned the question so I thought it wise to repost.
What I have seen:
When Plugging my device into any computer using any USB cable the result is the same.
If on - nothing happens; no notice on the PC and no charge on the phone. I have tried with debugging on/off, I have tried USB Mass storage mode no difference.
If off - It will turn on the phone and then the phone will show charging state though it will lose a charge and the PC will not say a device was plugged in. Also if phone is unplugged after it is on it will continue to say it is charging until a reboot.
If in Recovery Mode - Mounting any form of drive is not seen by the computer.
If in Download Mode - Device will say charging and drivers will attempt to install on the computer and I will see an unaccessible folder in "computer" that says "samsung i-9100"
I have just checked the web for updates and it says none found. To my limited understanding I am using a Stock ROM with an edited Kernel to give me root access.
I performed the update of the Kernel identically on both my and my fathers Identical phones and his has not had any problems. The only difference between the two is He is still on AT&T US; While I have moved to Hungary. But as I said the problem existed before that
If there is ANYTHING I can gather or forgot to submit that may offer some light to my problem please let me know.
Thank-You Very much for reading.
Regards,
Joshua Puckett

Fixed - I was using the cable that came with my Storm 2 BlackBerry; and tried after that a Cable I had bought at Radio Shack.
Once I tried the original Sammy cable it all worked;
Thanks to those who looked!

[Q] My failed rooting attempt, need your help

First thing, I am very very sorry if I posted this in the wrong topic, but I am in an extreme rush.
My phone is Sony Xperia Tipo (Si21), android 4.0.4 ICS.

I don't have a wireless router so I wanted to connect my phone to my PC through USB cable and share my internet to download some things. I found this tutorial which I decided to follow. In it, it said I needed to root my phone. I decided to do it and followed multiple tutorials but later on I found out they weren't working for ICS. I did download Java JDK and Android SDK along with files I needed and the google USB driver.
I found this tutorial from here though and thought it would work since this is quite an awesome community. I downloaded the files and ran the .bat file. Everything was going well and then and my phone restarted (as it should), but once it started again it was very slow (which could be caused by some backup that bat file created and my low phone memory with no SD card in it). That's all fine, but after like 1minute my screen goes black. I push the power button (used to lock/unlock phone) and only those 3 buttons glow on the push and turn off when I push again. All I can do is to pull out the battery and start the phone again. I restarted it a few times and once it acted normal, but when I accessed my galery it was messed up and when I tried xperia galery it was even worse (didn't show 3d well and there was lots of flickering and similar...). After that I restarted it to see if that would fix the messed up gallery and once phone booted screen went black again.
I tried the unroot option in the bat file and it gave me this:
This is my first android phone and I got it like couple of weeks ago so please have mercy on me ...
Sorry, I fixed it after couple of hours of work...had to restart my whole phone in the end.

[Q] S2 USB not working

Hi!
I have a problem with my S2.
So, yesterday, I tried to tether through USB and I saw it was't working and I said I'd change the ROM and it will work. I changed 3 ROMs and realised that USB wasn't working (neither in ROM or recovery) An hour ago, I tried connecting it to Odin and after 5 minutes, I succeded in Odin recognising it and I started flashing official software, but phone randomly disconnected. Now, if I try to connect it, I can't and the phone does not boot and does not enter recovery. What can I do?
PS: Sorry for bad english.
PS2: Tried connecting phone to 3 Windows 7 PCs and a Mac and it wasn't recognised at all.
worn out?
I'm not sure but I think the contact/connecter is worn out... I have a similar problem with random disconnects mainly when charging the phone but also sometimes with usb-pc connections. Changing to newer cables helps a bit but not entirely...
If it is not rom related I don't know what you can do more then trying another usb cable or buying a new phone. I guess that's not an option?
You also said your phone does not boot and you can't enter recovery... But what about "download mode"? As long as you can enter download mode you can fix the software in your phone but to do that you need the usb to be working correctly with no disconnects or else odin will mess up every time!
Replace USB board. Has been discussed here many times over the past month or so; search for those threads.
The USB port seems to be the weak point of the S2. It is seemingly the most replaced part for this phone.....I have had to do it myself, and have helped others in a similar situation. If you search my topics, you'll find one called 'video tutorial' which shows a step by step process for 'tearing down' an S2. This will help if you decide to replace the board yourself. Online shopping sites are a good place to source the part you need. But be advised, there are THREE different versions of this part (REV2.2, REV2.3 and REV2.4) see the photo below to find out where to look for the version number....
Make sure you get the same version as you remove, as a mismatch at this point is likely to cause other problems. ....

Finally....do not attempt to recover your phone until you have replaced this part.......the chances are that you will make things worse.....to the extent that your phone *may* become unrecoverable......

Well, KK has a few bugs on this device and I thought about downgrading to JB using LG Flash Tool. At 80% the USB cable just broke and the device just turned off (the battery was at 100%) and I wasn't able to go into Download mode again.
But, when I connect my phone to my pc (through a new USB cable), i can see my phone in Device Manager:
So I suppose the motherboard is not dead.
What can I do to revive it?
Could a JIG or this (I'm asking about this one as I don't have any factory ROM backup, and it will be hard to get one) work?

S905XQ Tomate - *HELP* How to put this *thing* into bootloader mode so I can flash it using USB Burnning Tool? [Pics included]

Hello XDA community! I need help putting this Tomate S905XQ box in bootloader mode so I can flash it using USB Burning tool.
I tried everything without luck.
What I have done so far:
Plugged the USB cable in the PC, hold the visible RESET then UPDATE buttons but unfortunelly, no dice. (Do I have to plug the ac adapter)
Also tried holding the "hidden inside" UPDATE button but also without any luck.
I want to flash Aidan's Custom ROM v9 on this box (1GB/8GB).
Any help is really appreciated, including how to backup this firmware because I haven't found any version on internet.

Try shorting it , the pins are on the chip just above where it says 905x , have the box attached via usb and have the usb burn tool open , get somehing like sim tray tool and one by one place it in between the pins untill it shorts it will connect ...you may or may not need power plugged in and make sure you use the otg usb slot..
Good luck
Thank you very much for your reply! I'll try that on the weekend.
as mentioned above shorting the pins AKA Mask ROM Mode will be your awnser, look at this thread, look for same type of chip as you have (M logo) even if chip aint the same number mask rom mode will probobly (but not always) be the same, there are 2 chips similar to yours in the thread, so try with those 2 first

Again, not my Picture.
Acording to Huawei, You have to Use HiSuite to recover it.
1. Put the Phone into Fast Boot. AND conect to PC
2. Open HiSuite on Your PC and click on Recovery mode or whatever its called.
3. i donk know i forgot.
anyways, i get this nice little message
(In translated, this means That: Your Device doesnt support System Recovery.
Bro wth
Anyways, our phone story doesnt end there...
I tried doing it without the Computer.
using eRecovery!!! not surprising i know...
Still, it was stuck on booting animation trying to enter eRecovery.
According to Huawei, "this message is displayed when a system file is replaced or modified, or the system is manually updated to an unofficial version". They were responding to another user with the same issue as mine.
I think that this is the Issue. Still, the instructions to fix it, dont work. (as tested above.)
Tutorials show the eRecovery method without the PC.
Here are some info i found:
Another Guy having the same issue:
i forgot the link but someone else on XDA Had the same issue.
please help!!!
