Xperia SP flickering screen when flashing new kernels / ROMs. - Xperia SP Q&A, Help & Troubleshooting

Hey,
Whenever I try to flash another kernel which is required to flash a new rom to my SP, everything works just fine. Except that when I finish the flashing and boot up to the ROM, the screen seems to flicker a lot...
I tried turning auto brightness off, flashing another compatible kernel, and flashing a couple of scripts that claimed to fix the issue...
I am currently at the stock firmware, rooted and with unlocked bootloader.
What is weird is, when I flash the stock 12.1.A.1.205 firmware back...the screen stops flickering.
Any ideas?
Thanks in advance

It's not only the cm11 kernel, other kernels like DooMLoRD kernel, which is based on the stock fw also has this problem..
Are you saying that I use a lower firmware kernel on a newer firmware?

DooMLoRD kernel based 12.1.A.0.266.
I advise you use cm11 for LBL + wiliams kernel v7.. => no flickeris bug

Ok so I should've mentioned that my bl is unlocked...
Also, williams kernel v7 is for 4.3...
I'm trying to flash cm11, for cm11 there's williams kernel v4...
I tried both the stock cm11 kernel and williams one and they both gave me flickering screen...
Any other ideas?

Ok so I tested it out today...and it doesn't work
I am now convinced that it's a kernel problem, since I tried a lot of different versions of cm11, but I also used 4 different kernels, each one at the latest version, NOTHING!
Any other ideas?

Hm... I don't know..=( sorry
I tried to write in support of the CM. But the answer is no.

Thanks for your time anyway

As win32r said, you should try a cm11 based ROM but for locked bootloader (they work for ubl too). With these roms you can use a kernel based on stock ( for example stock kernel or Williams kernel Sony version) which should fix your issue.
All roms that are for LBL will work with the stock kernel or Williams kernel v7. I wrote something about this in the Williams kernel website : http://williams-kernel.tk/help.php and I'll probably write this info on xda too if I have some time.

Wow. Apparently, your kernel is the only one that that doesn't give me a flickering screen
I tried an unofficial cm11 build along with it and it worked like a charm!
I just can't thank you both enough...
Finally I got a fully working cm11 on my SP

[PRO][KERNEL] Riyal-based kernel with better touchscreen precision & SE logo

Hi, this is my first kernel, this based on the latest Ultima ICS kernel from riyal, with two minor tweaks
-now touchscreen reponse while swiping is 4px instead of 9px, so no more bumpy movements while draging items
-official "Sony Ericsson" boot logo
Information about the touchscreen problem (if you have not noticed it):
http://talk.sonymobile.com/thread/40474
the problem is present in latest FXP (but probably not in next's) and also in stock kernel ICS
The solutions was 99% done by nicklas lof, here:
http://review.cyanogenmod.com/#/c/22164/
Works in Stock ICS, 431 and 587, it should work with FXP releases too
Installation:
Flash kernel using fastboot
Flash original Riyal wifi Modules using CWM
Riyals kernel thread is here
I do not deserve any credits on this, I just moved a line in code to compile and changed logo. :good:
What is Stock ICS 538? or you mean 587
the recovery are same or did u update it too ?
I have to install the img with fastboot ... And I have everything right???
Thanks for this kernel. will give it try one of these days
New Kernel for PRO [MK16a/i]
Thanks dafsoftware :good:
So just to clarify. Everything is the same as Ultima ICS Kernel v1.4 with the changes you made for the touchscreen precision and SE-X logo. The WiFi modules to flash are also of the v1.4 too right?
I'll try this when you confirm my query, as I am running on the Stock ICS MK16a 4.1.B.0.587 (US) build. I'll try to post any issues that I come across after flashing
[email protected]
MK16a Rooted, BL Unlocked
Kernel: LuPuS-PRo-v3-LiNaRo
Stock ICS ROM .587
BB 77

You are right, this is based in Ultima ICS v1.4, in fact Riyal already has this in his sourcecode, so next's versión should already have this fix, you have to use v1.4 modules

I think GB was 2px, but with the current driver is quite hard to tap on links at 2px, I will compile one at 2px if you want to try
I use this kernel with stock ICS 587 and my phone gets freeze every time I unplug from charger and PC.
Anyone has the same problem?
Can you please update stock kernel to use this fix.
Or give some link to add recovery to stock kernel.
Thanks,
Rajesh

This is based on latest riyal changes, I think it has voltages messed up, so I will have to build it from stock kernel someday. I dont know how to add recovery to it.
I am, but not exactly when disconnecting the charger, only when its charging and very randomly, I think the source I am using has a messed up voltage table, I need to find the original voltage tables to fix it.

thanks again.

OK - after reading more it sounds like there has been some structural change to the driver model (something that needs fixed at a deeper level). Anyway, it would be great if you could additionally provide us with a ROM set at 2px just so we can see for ourselves.
Ext4
Does this kernel support the Ext4 partition? Great kernel by the way...
Edit : and.... Swap partition?
Even better than that, I notice that the Touch Move app has a "tune" mode which allows the user to tune the sensitivity themself. It's currently only compatible with a couple of GSII custom kernels:
http://tegrak2x.blogspot.co.uk/2011/10/touch-move-tune-compatible-kernels.html?m=1
It would be interesting to see if we could get Touch Move Tune working on Xperia devices too.

In settings, can you open up the PAC-man setting? Mine crash the settings... "Unfortunately, Settings has stopped".

Repair with official firmware and check the camera there or flash latest gdx top on nAa kernel
The official firmware it will flash stock Rom and kernel to
Info:
Also if you have plans to relock the bootloader must do it only in stock kernel..NEVER RELOCK BOOTLOADER ON CUSTOM KERNEL

I flashed elemental kernel on latest hrc ota and seems to have broken the accelerator. Where can I get the stock kernel?

Which kernel to use with samsung's new bootloader

Hi, so unfortunately I'd flash the new samsung bootloader (the 4.4 one) and now I can't flash a custom kernel (e.g. : pureCM), it just boot into a black screen
I can just boot on latest Samsung roms with official kernel ans CM/CM derivatives with the stock kernel that comes with
So do someone knows what to do? Is there a way to go back to the old bootloader or to flash these kernels?
Thanks in advance and sorry if I mispelled some words !
both boeffla and agni don't work? Maybe this should be directed to @Hbohd since @psndna88 has no phone atm

Do you know which bootloader it is - XXUFNI3 or XXUFNJ1? (It should be the same as your baseband unless you flashed a new modem).

My baseband is XXUFNI3 and I haven't flashed another modem so my bootloader should be the same I guess

So I just flashed everything from zero. I reflash samsung official rom through Odin, reflashed crDroid and finally flashed Boeffla kernel, and it worked great ! Guess maybe the boeffla kernel I first downloaded was corrupted or maybe something else. Anyway, thanks a lot!
