I have been running on Cooks I777UCMD8 rom for about 2 months now and have had multiple powering issues. Have tried all the basic trouble shooting, not sure if its the Rom causing the issues or the AJK noswap Kernel, but nothing has been tweaked, running as is. The booting issue is when connecting a USB cable while the phone is powered off, if you try to turn the phone on while the USB cable is still attached you get a POWER RESET OR UNKNOWN UPLOAD MODE error message, only way to avoid it is to remove the usb cable and hold power button then it powers up normally.
now the problem with the USB cable, and i feel these two are possibly related, my phone no longer recognizes when its attached to a computer usb hub, it charges, but dose not enter into mass storage mode, nor does the computer recognize that the phone is attached, i have tried on multiple computers with same results, and yes all drivers are downloaded on computers. Further information; Before this problem began accruing, I would get error messages after attaching the phone to a pc VIA usb cable saying ( ONE OF THE USB DEVICES ATTACHED TO THIS COMPUTER HAVE MALFUNCTIONED, AND WINDOWS DOES NOT RECOGNIZE IT ) also, after plugging in the usb cable and windows attempted to download the drivers this error also appeared ( DEVICE SOFTWARE WAS NOT SUCCESSFULLY INSTALLED, CONSULT WITH YOUR DEVICE MANUFACTURER FOR ASSISTANCE ) it later resolved itself for a short time ( couple days ) but now when i connect the phone, nothing happens... i'm hoping somebody has had similar USB problems after flashing a new rom and knows whats going on.
additional information:
- i have two Galaxy S2 phones both running cooks-i777ucmd8 rom and both phones have had the exact same issues.
- previous problems also include boot looping, and frozen lock screen upon powering up the phone. has not happen in a while.

Hi all... i got my V for a month and now it is not charging anymore. neither from the ac adapter nor my computer usb..and my computer couldnt detect my phone is plug to the USB port....just nothing pops out. The debugging mode status icon, and the storage icon is not shown on my phone.
basically... i tried everything i found on Google...
reboot my phone, pop out the battery, change cable[from other optimus V], changed battery, different ports on my computer, different computer, different AC adapter, different SD card, format my SD card, factory reset, and the last thing i tried is to rooted my phone and flash with a I.H.O CM7.1 ROM.
no hope at all; however, when i plugged to the usb port or the ac adapter, then i take out the battery.. the phone does power up and say required battery....
so, if anyone had this problem before and solved it.. please help me out. between, i cant return the phone anymore.. it is over a month.
forgot to mention... it is the second time this charging issue happened. the first time, it fixed itself after i plugged into the PC, windows recognized it, and installed the drivers. [well, i already installed the driver before this happened, because i was doing some coding and debugging]
this time.... windows is doing nothing, no message pop out, no new driver found.. just nothing. and my phone doesn't shows the debugging icon on the status bar even thought i ticked the debugged mode On, and connected to the usb.
sorry for my bad grammar =[
maybe see if your pc recognizes it while rebooted into recovery.
you could also try removing all the lg and Android drivers in device manager (select show hidden devices to get at them) and then plugging the phone into the pc again.
or use a Ubuntu "live cd" to check the connectability... micro$oftware is uppity, my kid's windoze computer doesn't like my v, although it used to see it fine.
I've also read that toggling debugging, disconnecting and reconnecting the cable, then toggling usb debugging again can help.
also, froyo roms are supposed to go to a charge mode when turned off but still plugged in.
So the ota screwed up my phone. I was able to connect and intstall the stock eoh3 for xda the phone now starts up but I am unable to connect USB to root or flash any new rooms with Odin I can only connect Odin if the phone is booted up and debug and mock locations are on. If I pull the battery and put it in download mode it will not connect to the pc it just shows as an unknown device. I have reloaded drivers ect but not getting anywhere. Any ideas?
Try another cable if you have one, and try putting the drivers on another PC. For reasons I still haven't figured out, my home desktop PC quit connecting a couple of ROM's ago, and it won't even let me reinstall the drivers. I have a laptop that works fine (so I haven't gone into major troubleshooting) and my work PC also connects fine.
If the same issue repeats on other PC's and cables, there may be something wrong with your mini USB port. I had to have mine replaced a few months back.
Hi guys, i realy need your help, my phone is dead.
My I9100 worked fine for two years, I flashed lots of custom firmwares by Odin. Half a moth ago, when I was going to sleep, I plugged in the charger as usually, and noticed, that it started beeping occasionally. On the display it indicated smth like: Charging... than Not Charging... than Charging and so on.
I thought that I plugged the charger incorrectly and replugged it, but it didn't helped. I was very tired and just simply turned the soud off and left the phone charging. In the morning it indicated that it is charging even when the charger was unplugged.
So I've flashed the firmware - no help, than kernel from stock to fillz - no help , than siyah than again to stock - no help. All flashings were maid via CWM. I realized that flashing will not help when I turned off the phone and it was indicating that it is charging.
I decided not to do anythig. Only USB mode didn't worked because when you want to use your phone as USB you should open the apropriate mode on the phone than there will be smth like : plug the USB data cable to enter the USB data transfer mode. I couldn't do this because my phone thought that the cable is already plugged. In forums i've got hints that my micro usb should be cleaned or small board should be replaced. So i decided to clean it. I disassembled the phone and cleaned that board with micro USB. Than turned on the phone, and connected the cable. Phone recognized it and I managed to transfer files from pc to phone. From this point I can say that all terminals on micro USB are ok.
When i unplugged the cable, phone thought that it is plugged((
The most awful part:
I decided to flash it one more time and go to stock via backup made by CWM a year ago.
But during this process the phone made a reboot by itself and after that there was no loading. I can see only name of the device and thats it.
No recovery. Only download mode.
When i connect it to PC in download mode, there is a sound that USB is connected but the device is Unknown. There is no any information about this device in dev manager on PC. I tried two USB cables, all usb ports, two laptops, all versions of USB drivers for my phone.
Earlier, drivers worked well, but now i can't understand where is the problem: Is the problem still connected with my micro usb port or i just erased boot sector and it is already brick.
I gave my phone to service center, they told that they can't help me with this. They say that usb is ok, we don't know why it is not detecting by pc.
Can the board replacement help in this issue or maybe i can do smth. in linux with my device ??? I'll appreciate any suggestions.
Yesterday I talked to representatives of service center and they told me that the problem is that internal memory is damaged and they cant flash the phone.
I took the phone and tried to flash it via Heimdall with brick fix pit.
After using this pit file, the phone was flashed normally and even turned on normally.
But in the phone info menu I saw no any data about internal memory. (It was damaged and required format). I tried format through phone menu and it did nothing.
I decided to flash the phone via Odin with normal 16 GB pit file and had a bad luck. I experienced freez during repartition. After this, phone is a complete brick.
When I connect it to PC without battery pressing vol down and rower buttons it connects as unknown device but there is nothing on the phone display. No recavery no download mode. Nothing - just reflection of my frustrated face).
Currently i'm tring to make a Jtag, maybe it'll put it in the download mode, but hope is dying....
I've herad somewhere that it is possible to put it in the download mode in linux. If somone did this, could you please give me the contact of this person?
Hi, first post here.. so Hi
I have an issue with my S3, i can't get my pc to detect it in download mode at all, no reaction from windows.. if didnt plug it in to the pc at all, it worked once, and it took me reinstalling drivers for hours to get it working, this is when i first rooted the phone using the cf-root method..
When i wanted to install a custom rom a few months ago i discovered it went back to not getting detected and has stayed that way
it's as if i've not connected it to the pc at all, i'm using a rear usb port, with the original cable, below is a short list of what i've tried
Tried 3 different cables
Used a brand new install of windows 7 with SP1
tried various Samsung ADB Drivers
Tried every single USB port, front and back on my pc
Used as many different USB Debugging options as possible
I noticed that when i turn on USB debugging after enabling developer mode, nothing changes on the pc, if i remember rightly my S2 made windows install the adb driver when i turned USB debugging on..
Any help is appreciated with this, never had any of this happen with my S2 lol :/ i've been messing around on and off the last few months with it, thankfully there's Mobile Odin and also Nandroid backups for me to fall back on
Pulling the battery with the cable plugged in while my S3 was in download mode is what fixed this for me...
With the usb cable plugged into the PC but NOT the phone, go into download mode.
Connect cable to the phone, then pull the battery out.
Once windows detects the phone and installs drivers it's safe to put the battery back in.
Phone will be detected by Odin/ CyanogenMod installer and so on.
Why in hell having the battery in stops windows detecting the phone in download mode is beyond me.. unless samsung did it on purpose? lol..
Installed CM 11 using the above method and it went perfectly, but i do have to use the above method whenever i want to flash something using my pc, so it's more of a work around than a fix..
Fix was found on YouTube of all places! hope this helps anyone else
Hello, I have issues connecting my S3 international model (i9300) to any PC. It has CM11 since at least 6+ months and it worked just fine and connected to my PC two days ago just fine.
Some days ago, it started bootlooping because of the common power button stuck problem [turned on by itself when battery inserted, and rebooted in the Samsung logo, which doesn't even let you go to DOWNLOAD mode or Recovery because it just reboots after a few seconds]
Yesterday I disassembled it following fixit guides and youtube step by step guides to make sure I didn't break anything. I saw the button problem was internal (the button apparently works fine, but internally it has a closed circuit so it seems as pressed). I assembled my phone again and went to bed. Today it was working without bootloop. I saw this as an opportunity to make all the required backups just in case it went to bootloop again but I couldn't get anything from it. Windows doesn't recognize it at all, not even during boot. Here is what I tried:
*Tried in several PCs/Notebooks/OS with different cables that work with other phones
*In all cases it charges the battery, but the PC doesn't see it as a device.
*I rebooted the phone by software (so I don't press the power button at risk of getting bootloop again) going to terminal emulator and using 'reboot' command.
*Rebooting the phone connected to the PCs doesn't either cause any device to be detected by the PC during the booting of the phone.
*Thinking it might be the port of my phone, I tried an OTG adaptor and several pendrives. They all were detected by the phone and I was able to write and read the USB drives.

At first I suspected I left a ribbon/flex cable not connected to the board, but being able to use OTG USB drives and being able to charge it didn't convince me it was the case. I want to avoid disassembling it without knowing first which ribbon to look at and any other test/information you could tell me to provide in order to find the solution.
