Need help with screen issue

Hi bros
I am using Galaxy. TAB P1000GSM, I don't remember exactly the using history, but one day after flash new firmwares my TAB got into the bootloop state until now.
I had tried to flash any kind of firmwares with any solutions which I found on XDA included the Overcom Experience.
With any Gingerbread and newer firmware, my Tab was flashed completely without errors but always got into the bootloop state.
Finally I flash a 2.2 stock firmware, and after flash completed without errors, the Tab boot normally to the setting screen, but the touch screen and all soft button did not work, except the power and volume buttons.
I there anyone got experience with this problem? Pls give me some advices to save me Tab? You will save my life:thumbup:
Sorry for my bad english!
Thanks in advanced!

I boot into recovery mode, but only can use volume key for moving up/down, select the menu items by press the power key does not work!

when in recovery mode use the up/down volume to scroll and use the Home button on the screen to select. Clear the data then clear the cache. Then go to advanced and clear dalvik cache.
Thanks! But my Tab in recovery mode can be used with volume key, but both home key and power key do not work!

you sure you have P1000 and not P1000N or P1000L (check the back of your tab)
Ofcourse I sure that. It a P1000 GSM 16GB version!

Ok. Just asking.
Because touch screen driver is the only different of P1000L/N to P1000
also GSM and 16GB

No, I mean there are two sets of ROMs/kernel (drivers is in kernel)
one for the P1000 and one for P1000L/N
but if you are sure you are P1000 and already flashing P1000 kernel/ROM, then no, I cannot recommend a P1000L/N kernel to use.
Unless you also have doubt about your P1000.

I used Overcom method already, the Recovery worked well, but the Tab went into the bootloop state.
Assuming that my Tab now has wrong bootloader and it is locked. So is there anyone can tell me how to fix it?
Thanks all!

Restock again using GB stock safe. It contains bootloader, so if your theory is right, that should fix it.

Might be a good idea. Flash overcome kernel, then immediately flash cm9,
The mtd repartition might help.

If he's on stock he probably doesn't have recovery or root access
He's rooted but i don't think he has recovery?

So IF he boot recovery it will just factory reset.

If you are rooted and have no recovery just get Rom manager from play store and install recovery from it, the app also has a reboot in recovery option

This is the easiest way.
Procedure for our newbie friend.
1. Download rom manager from play store.
2. Open the apps then click flash ClockworkMod Recovery (need internet connection to flash)
3. After flashing click Reboot into recovery
I suggest that use the old clockworkmod(Version 5.0.2.6) because base from my experienced i always have a hard time rebooting using the touch version. It's like there is a time out, i ended always into bootloop and it takes an hour to reboot.

[Q] Blackscreen problem please help

Good day to all of you, please help me with my friend's Galaxy S.

You can try a wipe data in recovery, if it works (power button +volume up + home when the phone is off)
Okay do what the guy above said,
1. Get into Recovery Mode(Volume up + Power Button)
2. Wipe data and cache
Please reply if anything happens.

Bricked or What?? And how to fix. Help Please!!!!

This isnt my phone but me and my friend successfully rooted his galaxy mini but when we flashed CWM we must have used the wrong one from the app and bricked the device or something as the device wont turn on. Is this bricked and if it is how can we unbrick it.
Thanks
If you can go into the download mode just flash stock rom through odin

The wrong one from an app... It sounds like Rom Manager. If I'm right, then USB jig or service.

Thanks guys, will the phone still flash even if the phone doesnt tirn on? I will try flashing with odin this weekend but if it doesnt work do you think samsung could fix it?

To find out if it's a "soft brick" or "hard brick" try going to "Download Mode" on the Mini. Do this by turning off the phone simultaneously pressing the Volume Down + Power + Home. When prompted, press Volume Up to confirm.
If there is a Download Mode, the phone just got a "soft brick" which means you can fix it on your own. If there is no Download mode, you're pretty much screwed.
IF there is a Download Mode, then it means you can still flash a ROM/firmware via ODIN. But I suggest flashing the right CF root kernel for the Samsung Galaxy Mini first. That will probably fix the phone's failure to boot. If it doesn't reboot properly after rooting, then I would suggest you flash a new ROM/firmware instead.

Oh, if there is a Download Mode just as I explained above, you can still flash any ROM or kernel via ODIN. Cheers!

If it seems like you can't get into download mode, there is a trick (it worked for me, when I thought my phone was hard-bricked, but obviously TRY THIS AT YOUR OWN RISK.
Get a friend to help - it's almost impossible to do this by yourself (unless you were born with three hands) :silly:
Take out the battery, sim-card and SD-card
While holding down all three buttons for download mode (Volume Down + Power + Home), get your friend to insert the battery.
Keep holding down all three buttons until you see download mode (can take up to a couple of minutes).
If it doesn't work at first, keep trying - it took me about three of four tries before that lovely sign came up :laugh:
Good luck.
PS: sorry I really can't remember where I got this from, so can't give due credit. If I'm plagiarising anyone, please let me know and I'll fix it.

Thanks for the reply, yes i have correct files, still will try yours, (once it will boot then further i will deal easily) currently have given the phone to a local repair person, he said something is wonky with IC chip so ROM is not flashing properly.
Would try your thing soon, thanks!
