computer won't recognize my phone - Galaxy S II Q&A, Help & Troubleshooting

Hi,
My Computer won't recognize my galaxy s2
before was a "unknown device" so i've installed drivers & kies..... tried many things ... and the "unknown device" doesn't appear anymore
but when i plug in the phone nothing happens , just charges.. and in download mode nothing happens...
HELP

Turn on USB debugging in settings/developer options.

tried.
and what about the "download mode"

But you didn't say you'd tried it in your OP, did you ? (Saying please when you're asking for help tends to work wonders as well)
Stuff to try - and if you've tried all this, either you're doing something wrong or your phone is busted, in that case take it to a service centre:
*Must run Odin as administrator in Windoze.
*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)
*Uninstall Kies, reboot, redownload & reinstall it, reboot, try the flash again.
*Run Windoze Update.
*And if all this fails, try a different PC.

[q] odin cant detct my s2 gt-i9100

I was having a rooted phone yesterday with stock gingerbread
I unrooted my phone by instllaing the stock ICS.
Now i want to root my phone but odin cant detect my phone.
I tried reinstalling samsung kies but still cant detect.

1st make sure your Samsung USB device driver got installed completely (IMPORTANT)
2nd tick the USB debuging at the developer options.
Then you should be able to detect your device.

Stuff to try/check when Odin doesn't work:-
*Must run Odin as administrator in Windoze.
*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 (you need the drivers that come with Kies for Odin to work unless Windoze has automatically downloaded/installed them the first time you connected your phone to your PC).
*Check the rom/kernel you download for corruption. Programs like 7Zip, IZarc, WinRar, etc will allow you to 'test' the rom file you download. If there are any errors/any of the files fail the test, bad download. Try again/try downloading with a different internet connection if it keeps happening.
*Run Windoze Update.
Try all of these if necessary. Not just one or two & say 'But I tried two things on the list & they didn't work'. And if all this fails, try a different PC. And if it doesn't work first go on the different PC, go thru as many of the above steps as necessary on the 2nd PC.

[Q] Help ~ After flashing firmware.

I Did what as mention in the firmware change guide.
everything seem to go fine.
after flashing the firmware with odin the phone auto reboot, it can start but after the samsung logo and then it don't move anymore
i can go to xRecovery and Downloadmode.
Anywhere to get the phone back?
Boot into recovery & do a wipe/factory reset.
Done, still can't ><
Well you didn't say that in your OP, did you ?
Bootloop thread. Pay particular attention to the title of the thread (might want to read the thread as well).
Hope it work. I Trying to flash the rom now :X
Erm, i tried to flash the PDA/Phone/CSC
but it almost end and it stuck at the flashing there?
i waited for nearly 10minutes?....
That's either a bad download (I'd re-download the package you're trying to flash) or you need to go thru the following steps:-
Stuff to try when Odin doesn't work
*Must run Odin as administrator in Windoze.
*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.

*Run Windoze Update.
*And if all this fails, try a different PC.
If you do get to the last step (trying a different PC) and it doesn't work first time on the other PC, then you go thru the steps with that PC.
Wait now i'm having a problem
Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again
HELP Please! ><!!!

[Q] Usb and rooting problem please help me

Hello all i just go a samsung galaxy s2 GT-I9100 and when i plug my usb cable my pc wont recognize my phone resulting in a unknown device i cannot use mass storage,debugging mode etc.. all i get is a mpt connection and my phone is charging.Im using windows 7 ultimate 64.
Now i did use the search function on the forum i found and tried these next solution.
1.I installed the latest samsung Kies 2.3.2.12054_20 it wont see my device.
2.I tried the usb_drivers_GalaxyS_x64 i went to device manager and manually installed the drivers (including subfolder)
3.I did a factory reset about 3 time, i even tried the *#7284# code whit pda option on usb,
4.I installed the 1.3.1900.0 usb drivers that i found on the forum, i used
usb host controller i even installed the google usb drivers 0 luck.
All i want is to root my phone using odin in download mode but my pc wont recognize my phone in debugging mode im using a 2.3.5 android and want to upgrade to aokp 4.0.4 is there any way to root my phone??
Try a different USB cable, different USB port and/or different computer.
I did 3 different cables on 3 diferente computers.
Try everything on this list if necessary, and if you still can't get it working then it's probably user error:-
*Must run Odin as administrator in Windoze.
*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.
*Check the rom/kernel you download for corruption. Programs like 7Zip, IZarc, WinRar, etc will allow you to 'test' the rom file you download. If there are any errors/any of the files fail the test, bad download. Try again/try downloading with a different internet connection if it keeps happening.
*Run Windoze Update.
And if all this fails, try a different PC. And if it doesn't work first time on the different PC, go thru the above steps with the different PC.
As mentioned above, if it's not happening after going thru the above steps, probably user error somewhere along the line, and that's going to be impossible for anyone here to say what as we're not looking over your shoulder.

[HELP] My i9100 has soft-bricked and odin doesnt pick up my device

lemme start by saying what i did that caused the problem
i installed PFittech 1.0.4 and everything was moving fine untill touchwiz began FCing alot. i dont use touchwiz anyway (as i had set Apex to default) so i thought i could remove it safely without any reprocussions. i used titanium backup to do a force uninstall but the phone rebooted into a black screen. I cannot get into recovery move at all so i tried to reflash the kernel in hopes that my recovery would be fixed.. I got into download mode just fine but neither odin or windows can connect to my phone
i really need help because nothing from the other posts related to this topic is working, i followed a few other posts and nothing is making odin pick up my device in download mode

dont have another pc available so im stuck with this one, tried other USB cables, tried running odin as administrator, tried uninstalling n reinstalling kies, tried another version of odin (1.87)
nothing is working -_-
i should mention that when i attempt to boot normally, the PC is able to discover the drivers and connect to the device. even MTP connects and im able to view the contents of my phone's memory (for some reason, its all 0MB in size)
based on my readings, havent heard anyone having my specific symptoms for my phone.. im getting more and more depressed because i use my phone so much and now that its down and i cant fix it.. just feeling sad :crying:
and all this because i tried to uninstall touchwiz.. :crying:
ok this is what i will try doing
since my PC recognizes my phone only when it boots normally, i will try to flash a recovery image by dropping it on my SD card, then flashing it using droid explorer's "flash recovery image" option - REALLY hope this works
EDIT
nope - not working, even after flashing using droid explorer phone reboots into black screen, no recovery, no nothing..
i recently tried odin3 v 3.04 and odin still doesnt detect my phone in download mode.. drivers are still saying "unknown device" when i boot into download mode.. ive uninstalled and reinstalled and restarted both pc and phone so many times i just feel helpless right now.. like i should just give up and buy a new phone
Need this question answered
does odin pic up the ID:COM on a device whether it is in download mode or not? based on what i read here
http://forum.xda-developers.com/archive/index.php/t-1484607.htm
odin is capable of picking up on an ID:COM even if the device isnt in download mode - in my case, odin isnt picking it up at all nd as is, windows is still able to pick up my device if i boot it normally and load MTP and the correct drivers
24 hours now since problem occured and i have made no progress whatsoever.. feeling like giving up.. dont know what to do, and dont think anyone can help me anymore -_-
After 26 hrs of talking to myself and dedication - i finally solved my problem.. i decided to update my windows base and cleared the registry on all installations and all current associated drivers, reinstalled kies, updated new drivers and when connected my phone which was in download mode my phone connected as a "gadget serial" device.. with this - odin was able to pick up on my phone and i flashed a new kernel + recovery.. with that flashed back my rom and bam - back to status

Just an observation... isn't this more or less what MistahBungle said to do in his post in his last suggestion? (short of clearing the registry entries, which is a good idea as well.)

honestly, i tried everything he suggested, but i suppose without the windows update + updating the USB drivers through kies (not download them by themself) - i possibly wouldnt have been successful. i read a tutorial that told me that kies could put my phone into download mode for an update - so what i did was clear registry, uninstall all current drivers and manually made kies reinstall them.. then after that, connected my phone while it was on (with the screen still blank) and selected the option to peform firmware update from kies (which put my phone into download mode) from there, when my phone got into download mode the new drivers loaded up and thats when odin was able to connect
in my situation, the constant plugging out and plugging in and hoping windows by itself could pick up the drivers never helped at all.. few people stated that i didnt need kies and that it interferes with it so what i did was only install the drivers and got rid of kies.. however in my case if not for kies i wouldnt have been able to connect to odin

[SOLVED] Installed incorrect ROM type.

I was installing the Build 6 AOKP rom on my already AOKP rommed phone. After installing both Gapps and the ROM, I realised I installed the GT-I9300 rom instead. Obviously the phone was bricked. CWM Recovery via the 3 key shortcut isn't working - it stays on the splash logo, but download mode works. From previous experiences ODIN doesn't seem to work, but I'll try it if necessary. I can't get a replacement from Vodafone (it's registered as a GT-I9100T but rommed as a GT-I9100) since its warranty is long gone. Is there anything I can do to get my precious phone back?
Thanks in advance.
Get a Vodafone stock rom from Samfirmware, boot the phone into download mode, flash rom with Odin (search; how to Odin flash mentioned here thousands of times).
That's all you've got. You have no other way of fixing it (and even then you may not be able to).
If it won't work (phone & pc won't recognise each other), try the following troubleshooting steps:-
*Must run Odin as administrator in Windoze.
*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.
*Run Windoze Update.
*And if all these steps fail, try a different PC. And if it won't work first time on another PC, go thru the above steps on that PC. Still won't work ? JTAG repair or repair by service centre/authorised repairer.

Thank you so much, somehow ODIN decided to sense the phone spontaneously.
