[Q] Flickering screen after bootloader flash

[nicktaken]

Forgive if there are similar threads about this topic.

I suffered from scrolling cwm so i tried this fix: http://xdaforums.com/showpost.php?p=27830023&postcount=41

It worked excellent but when i lock my screen and unlock it again it starts flickering like shown in this video: http://youtu.be/P6fMxjFdpJE

I have tried to do factory resets both from recovery and flash an original firmware. Nothing works.
Is it possible to get this fixed or am i screwed?

I just wanted to say the same. Flash the kernel from pershoot website, it should fix it.

It doesn´t work for me.

But I dont use 3G anyway so can I just go with P7510 firmware which works?

Alright I got it to work! I didn´t get it that I should flash the kernel in cwm so I flashed it in Samsungs recovery

When you tried the fix noted above, I assume the screen didn't roll when you rebooted then into CWM recovery. At that point did you flash a ROM and THEN reboot to find the flicker after locking the screen, or did you do a reboot back into the same stock HC after flashing the bootloader and experience the problem?

I'm contemplating flashing this same bootloader because I have a rolling CWM5.5.0.4 right now and I want to stabilize it - but just so that I can root...not thinking about a ROM just yet...

Just to inform you all, i also had to flash a different bootloader after installing cm9 on my p7511, wich is in fact a 7510. For the records, pershoot made the new bootloader for exactly that issue, not backwards. But seems to work also.

What i deal now with, is that after flashing the uk ics for p7510 to my tab, the stock recovery doesn't recognize my sdcard. Can't mount sdcard...

Could be that a repartitioning with pit file will be necessary afterwards for us all.

Edit: thanks to the wise help of msedek, i know by now that my hind was totaly wrong. My mentioned point has to do with the Changes within stock recovery of ics, which have been made to prevent changes from there.

 

[djmatt604]

Getting more confident..

OK so it is sounding like this is definitely better. One more question:

I'm following the stickied root guide in General and that method uses CWM 4.0.0.4...I had reflashed that version. If I want to flash this boot loader should I flash 5.5.0.4 first? Or does it matter if I'm just trying to root right now?

EDIT: Flashed the bootloader which straightened out the recovery!! Successfully rooted after that. Downloaded root apps (ROM manager/Titanium/etc). Then turned off my screen - FLICKER CITY!

http://xdaforums.com/showthread.php?t=1680738 <<< THIS fixed it. Load this kernel into the root of your tablet and flash it with CWM. Seems to have done the trick nicely and I'm exploring my newly rooted tab! My wife no longer wants to kill me either.

What ROM or firmware are you running? What exactly have you done with the device up to this point? Are you 3G or WiFi? Need more detail...

Flicker screen after screen lock\timeout

I have the same problem on my P7500 3G and the minute i load the bootloader to fix CWM recovery rolling i get the screen flickering after lock screen.

Rom: ICS 4.0.4
Build Number: IMM76D.XXLQ8
BaseBand7500XXlQ8
Kernel: 3.1.10

 

[Compendyum]

Still stuck.

Hi guys,

Gtab 10.1 Wifi here. Fix didn't worked, somehow...

After installing official ics from Samsung and rooted, i had the same insane flicker issue. I followed this thread - http://xdaforums.com/showthread.php?t=1680738 - , flashed new kernel, and now i cant pass Samsung Galaxy Tab logo for some reason, not even past half an hour.

Im in a dead end, even tried installing back CM9 but it also wont pass the splashing blue screen.

Any ideas?

cheers!

EDIT : After some reboots, finally managed to boot into ICS (CM9) but now i was pushed back to the step 1, where I don't have a working camera, but I have root access and non official ICS from Cyanogen. I am afraid re-doing all my work and get stuck again in the scrambled screen after it updates the kernel..

I'm I missing something, guys?

Hi there!
Are you still having problems?does this guide here work for you?:
http://xdaforums.com/showthread.php?t=1555984
I've found something,the kernel flash package changes our devices' WiFi driver,that's why it doesn't work.
sorry for not giving a fix until tomorrow,it's sleep time here,I know my excuse will be accepted because you all care for basic human needs...

But please inform me if that guide(Pershoot's) has fixed your problem,thanks for that
