Default [Q] Screen flickering during boot.

If there already are threads about this, please direct me to them instead of flaming. I have searched through the forums without finding anything.

I got my 10.1 WiFi about a month ago, and can't figure out why this is happening, and if it is happening to anyone else. Every ICS rom I install makes the screen flicker during boot, and it will continue to flicker until I turn off the screen, and then back on. After that there are no problems at all. I had the same issue when I install CWM recovery. I had to try 3-4 different ones, before I found one that didn't flicker.

It seems to me, that it might be kernel related, but I am not sure.

Any input is welcome.


The box said 'Requires Windows XP or better'. So I installed Arch...

Same here, even 3.2 ROMs flickering for me . The only one that doesn't flick is Task ROM

Hey man, just got this sorted out

Try to follow this http://forum.xda-developers.com/show....php?t=1555984
Key part is that we need to unroot our tabs with North America stock. I think our "Non-NA" stock ROMs weren't really "unlocked" that's why custom kernel won't work well on them.

Super happy now with CM9 + latest pershoot kernel + latest CWM, smooth no flickering

Happy unrooting !

Make nand backup (if recovery flickers use rommanager)
Save it to PC
Wipe everything
Flash P7510UEKMP_P7510XABKMP_XAB.tar.md5 with odin
Reboot
Wipe everything again
Flash recovery.tar.md5 with odin
Reboot
Put this http://www.shabbypenguin.com/users/s..._10.1_root.zip to storage
Put nand backup to storage
flash the zip
Reboot
Restore nand

Finisch! You can now flash another recovery and any other rom without flicker
In fact there is no way to get the flickering back^^

Hello all.

I have the exact same problem as tristan202 which is

Every ICS rom I install makes the screen flicker during boot, and it will continue to flicker until I turn off the screen, and then back on. After that there are no problems at all.

I am sorry but i think that solutions bringed by "hylde" is not related to this problem but to another problem, through very similar, in clockwork recovery tool : same flickering screen.
I used the link, 2 weeks ago to solve this problem, using 5.5.0.4 version.

But the original thread problem is still unsolved. I tried other ICS roms but with same problem. I'd also like to keep root access.

Thanks to all

Well, I have almost the same problem. I am on overcome's rom, and I have a screen similar to yours. It is static, not rolling and it happens only once after reboot for two-three seconds before the lockscreen. After that it is ok, even when I lock the screen. Flashed again but nothing. I haven't found anything about that. Oh well. It may be weird but I can live with it. Has anyone encountered something like that before?

From

http://droidbasement.com/db-blog/?p=2479

Put it at the Root of your tab and reboot into recovery, then flash that zip file!

You should be good to go!

If not then you will have to flash back to stock kernel listed at the bottom of the second post or just re flash the Rom your choice, this will be nessesary if you flashed another kernel, Then go back and flash boot-cm_2636.4_ux_hc32-oc-xtra-vfpv3-d16_fp-010912.zip then you will be GTG!

Oh ya it took me 3 hours to figure this out for my self Your welcome! ------------------------------------------>
