[Q] Phone is not recognized in download mode (hardware problem) - Galaxy S II Q&A, Help & Troubleshooting

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?

[Q] [Help] Optimus V is not charging

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.

[Q] Windows Not Recognizing Device

Hi guys, was having a few problems with my phone and decided that I'd flash the stock ROM again.
Went into ODIN as you do, and as I was flashing the stock ROM, for some reason or another I heard the disconnect/reconnect noise that Windows makes when you remove a device then FAIL came up in ODIN.
Now my phone's stuck with a phone connecting to a computer on the charge screen, it can't go into recovery mode but it can go into download mode.
Tried connecting it to my PC in download mode, and even though I've got the Samsung USB Drivers installed I get the 'USB Device Not Recognized' message, which means I can't flash the stock ROM in ODIN anymore.
Does anyone have any advice? Thank you.

I have it installed, and I installed the USB drivers from the soft bricked sticky in this section. Neither have helped.
Hi!
Hi, you guys install ADB on your system? And also USB debugging mode on the phone?
Should be turned on which can be done by going to Settings>Applications>Development and select USB debugging.
Try this, for me its works

I can't even turn the phone on at the moment. Only thing I can do is go into Download mode.
Help
Try this, take out the battery, then press and hold the ON button for 7-10 seconds (the longer the better). Reinsert the battery, then press ON button to start it. This is a soft reset, and wipes the temporary memory and empties all remaining power in the circuits. This helps on many phones and even laptops that won't start properly or show anything on screen.
If this does not work, try the next step. Again, do as above. But after inserting the battery, do not turn the phone on, but press and hold the ON button and the HOME button at the same time for 7-10 seconds. This is a hard reset, and works best if done after a soft reset. Just be sure the battery has at least some juice in it and isn't empty. If possible, try with another battery if this does not work.
Hope this helps!
Try going to device manager, you will probably find your device as an unrecognized device, uninstall the drivers, unplug and then plug it again and see.
if the prblm is hard then do a fresh installation of kies,device etec etc.....but if u have ur device in the device list on pc then first uninstall it...if possible try recovery mode and reset...
I tried everything you guys have suggested and none of that worked. Anyone else got any ideas?
Try everything (and I mean everything) on the following list. Given the problems you've had & that you've already tried some of these things, I'd try another PC. And if it doesn't work first go on another PC, then go thru the list & try everything on the 2nd PC.
*Ensure Kies & it's processes aren't running in Windoze task manager. Kill them if they are.
*Try different USB ports; you must be using a 'powered' or mainboard port.
*Try different USB cables (particularly the cable that came with the phone if you're not using it now)
*Try different versions of Odin (search on here/Google)
*Uninstall Kies, reboot, redownload & reinstall it, reboot, try the flash again. Also run Windoze Update.
*And if all this fails, try a different PC.
Tried all the above and a different PC.
It didn't work. I could fix the phone if the computer would pick up that the phone's connected - it just doesn't.
Total Removal of KIES including registry entries .
Reboot PC install a new copy of Kies .
Phone backup data and factory reset .
Set phone to USB storage mode using the Samsung cable connect to PC and wait for Windows to find USB drivers .Remove cable reboot phone .
Start Kies connect with cable wait for Kies to find the phone .
Note USB Debugging OFF and cable connects to a direct motherboard port only .
Nothing then only further suggestion would be to Format the PC and start over with a clean Windows install .

I can't turn the phone on, it's stuck on the phone, triangle, PC screen.
I've tried fresh installs on three different PC's.

That's a forced download mode.
Try a blind flash to a stock firmware from Odin while connected to your computer with the phone on this screen. Even if Odin doesn't seem to register that it's connected. I've heard of at least one person this worked for.
At this point, you really have nothing to lose by trying this.
Bit of an update, I plugged it in again and it installed some drivers and ODIN picked it up. Only for it to disconnect a few moments later, now it keeps disconnecting and reconnecting over and over but ODIN's not picking it up.

I know you said you tried a different cable, but that sounds suspiciously like a bad cable.
It's not the cable, thanks any way.
Update 2: I managed to get it to connect long enough to flash the stock Kernel. Still didn't reboot. Then I connected it again and flashed the stock ROM, which bricked it again. Then I flashed the stock kernel and it works!
However, there is a problem:
When the phone gets turned off, it constantly shows the charging battery icon with warning triangle and a thermostat next to it. I can't turn the phone on because of this unless I go into Recovery mode and reboot system.
Any ideas? Thanks.

Now this sounds like a faulty/dirty/bad usb port.

This was my original thought and my reasoning for flashing a stock ROM in the first place!

I in no way recommend this, and not sure I would do it if I ever started having this issue...
BUT - I have heard that some people faced with this condition have fixed it by physically moving the small wafer board inside the USB port with a precision screwdriver (gently!) to a more "centered" position.
If that doesn't work, look at replacing that part. Either via warranty service if you still have it, or a service center.

SGS2 is not recognized as a USB device by windows

We had a power bump the other day while my phone was charging. since then the computer started to not recognize the usb device. I downloaded new drivers and tried all the old tricks I used to use to get it accepted by 4 different windows PC. I have tried multiple usb cables as well still no luck. The phone is still charging but sometimes it will be at 15% and then the indicator will flash to 100% charged and I have to restart the phone to get the indicator to ready properly and continue charging.
I have tried a factory reset to see if all the phone needed was a kick in the butt to start working again but that did nothing but lose my data. I think the usb mini port is blown from the bumps but if anyone has any suggestions it would be greatly appreciated. I am on the jellybean official all phone details are in my signature.
Is there any way to update the firmware and do rooting without a usb? Can i take external sd card and load stuff i want onto there and get to a rooted unlocked phone via recovery mode?
Replace the USB board/port. Cheap/quick/easy to do yourself. KeithRoss39 has a guide in General section which has all the info you need. Flashing stuff to/messing with your phone without having a way to recover (I.E the ability to Odin flash via USB) is foolish & invariably leads to a busted phone with no way of fixing it until you fix the USB board/port. So you might as well do that first.

[Q] Booting and USB problems running on Cooks-i777 Rom

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.

[Q] USB connection to PC suddenly not working. OTG and charging works.

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.
