i was using the cm10.2 nightly.
it was fine until i flashed a kernel and a recovery on my i9305.

devil dual boot n7000 kernel
devil dual boot n7000 recovery

after that my phone stuck on the boot logo and then it turned in to blue flashing screen.
then i flashed cwm recovery with odin and did 3 wipe.
next i install cm 10.2 back to my phone and then reboot.
it took a long time to boot form the logo into the cm rom.
it finally booted.
unfortunately, the monitor is not work at all.

so that, i use odin to restore the factory samsung stock rom.

m3.pit
MODEM_I9305XXBMA2_REV05_CL1213990.tar.md5

the phone was restored successfully.
again, it took me a long time to boot into the system
the touch screen is still not working.

additional information:
i flashed a touchable cwm recovery, but the touch function is also NOT working.
everything else works fine. the screen shows graphics, but not response to touches

can anyone help me?

THANK YOU VERY MUCH:'(

The only thing I can think of is flashing the stock ROM again, and wipe Cache, Dalvik, and a factory reset. Reboot.

Thanks for replying.

I did factory reset, 3 wipe. but the problem is still there.
I'm now trying to restore 4.0.x stock rom by odin see if the problem solved.

Re: 【HELP】my touch screen isn't working【urgent】

Your best bet might be to post over on XDA, where all of that stuff originated. I haven't used CM, nor fiddled with alternate kernels, and after bad experiences with CWM recovery I've stuck with TWRP.

I doubt that it's a coincidence that your touchscreen suddenly stopped responding so you probably just need to get the correct firmware, RPM, modem, kernel, etc to get it working again. Good luck.

thank you for replying.
theres a reply from xda
he said i burn out a component and require a paid for service repair ./_\...

i hope not... it is quite expensive.

i wish theres still ways to due with it

Re: 【HELP】my touch screen isn't working【urgent】

You flashed a Kernel meant for a different phone to your i9300? What were you thinking? The kernel is the core code that translates commands from your OS (Android, in this case) to the hardware. For example, when an app wants to draw a box in the middle of the screen, it tells the OS that. The OS then tells the Kernel. The kernel knows the hardware commands to make the screen turn on pixels exactly where needed.

The kernel you installed is for a note 7000. It doesn't have the same screen as an i9300. It's trying to tell the Note screen what to do, and the screen in your s3 doesn't understand. You're hosed. Whether trying to command an S3 screen with Note 7000 commands will damage the hardware I have no idea. The only way you're going to get this phone back, I suspect, is with JTAG service. What you need to do is flash the correct kernel onto the phone, but without a working screen I'm not sure how you can do that.

thank you for giving me advice.

why must i have a working screen to install a kernel?
Is it possible for to do that in recovery?

Re: 【HELP】my touch screen isn't working【urgent】

Don't you need to see the screen to use recovery?

sure. i can see the screen, but the touch fumction is not working.
i flashed the lastest cm, and a competable kernel. however, it is still not working.
probably i had burnt out a component:(

Re: 【HELP】my touch screen isn't working【urgent】

What kernel did you flash? Can you provide a link?
What carrier are you with?

Meyer,
It seems unlikely that flashing a wrong kernel would have messed up the hardware - do you agree?
Don't typical ROM files include the whole shebang (firmware, RPM, radios, kernel)?

You wrote "unfortunately, the monitor is not work at all." To me, that says the screen (monitor) is / was blank.

I agree it seems unlikely, but I don't claim enough hardware engineering knowledge to be sure. If, for example, the kernel he flashed was designed to drive an LCD screen, what effect would that have on an OLED screen? I would guess it simply wouldn't do anything, but perhaps it could trigger a higher voltage than the screen was designed for? I'm talking out of my a$$, of course. :)

I installed TWRP recovery for i9300 with touch capability. The touch screen didn't react to touch. On rebooting into the original Android firmware the touch screen worked fine. I then installed CWM touch capable recovery for i9300 and found that touch still didn't work in recovery but I could use the volume keys to move thru menu items and select with the power key as usual with CWM recoveries. On rebooting into the original OS again to check screen touch functionality I found that the screen was working fine in Android. I then used the CWM recovery to install CM11 for the i9300 onto the phone. One rebooting the touch functions failed to work and the phone just stayed at the language input screen awaiting input.
After reading many comments on XDA and other forums I have come to the conclusion that the problem is not a hardware one but rather a software problem as my installation and subsequent failures of touch screen capabilities under recovery while working fine in the OS shows.
Something here is on the nose!!! My Note II never gave me these problems and works fine with TWRP and CM12 to this day. The i9300 is a bucket of crap!
