Kernel reset problem - Xperia Arc Q&A, Help & Troubleshooting

Hello,
i've got a problem with my sony arc.
I was on jjhybrid 3.2 and doomkernel, and i had some problem with battery. So i tried to change the kernel with arcknight 3.3. After flashing the kernel with the fastboot command (fastboot boot boot.img) the kernel did not load. It appeared the new "logo" of arcknight kernel (batman) but after trying to boot, the phone did a reboot and then automatically appeared again the doomkernel, and the phone was bricked on the kernel logo. (android wouldn't load).
So i flashed via "flashtool" the original kernel, now the phone works and it does load the stock kernel and android too.
But i still can't change my kernel.
Every time i try, it flash the kernel, the new kernel tries to load, the new logo appeares, the phone reboot automatically, the stock kernel logo appeares again.
Does anybody know which problem it could be?
Thank you and sorry for my english.

Did you check if the kernel was compatible with the rom? if it is do a full re-flash of the ROM and re-flash the kernel

Thank you for reply.
By now, i don't know why, i tried again and it worked.
Now the phone works with new kernel.
Before that, i tried a full refresh of rom and kernel, but it didn't worked. Still the same problem appeared. The kernel was correct.
In practice, now the phone works and i don't know why. I can't comprehend what the problem was. Hope it doesn't happen again!
I suggest a movie: Paranormal phone activity 3.

[Q] Switching Kernels

Hey
So well I have a CM 7.2 Installed on my Arc with CWM Default Recovery.
I thought If trying out new firmwares so ThoughI'll download the Alpha of ICS from Doomlords post.
I downloaded all the stuff and started out with switching kernel to doomkernel from CWM. I opneed fast boot and flashed his kernel .img file.
It rebooted in His kernel and I flashed both of his files and the wifi patch or whatever. and Wiped chache and data and other suff and dalvick cache aswell.
When I rebooted then, It didnt show dom kernel's logo but CWM!
And Well, Then nothing happened and it froze for about 10min. :|
I tried flashing his kernel again and rebooting, It just shows doom's logo once afer reboot and den CWM!
Help somebody
You need to wipe it after flashing all too.
But CMW is appearing, a Recovery Mode? Or a boot image?
I tryied to but no result, but i dont installed the kernel from the post, than i will use my MIUI Rom
But good luck, if news, post to me
Well, Its a boot image but it goes into CMW recovery mode only
It's like the doom kernel is flashed only for 1 time booting :|
After 1st boot, Its CMW Recovery
I Have to wipe Kernel?
How to do that?
Via doom recovery?
Where's the option?
after flashing kernel,power on your phone,hit volume down,enter cwm,wipe everything,n go to "advance",wipe dalvik,then flash the rom..

How did you flash the kernel?
You have to flash it with fastboot flash boot boot.img .
If you're only typing fastboot boot boot.img, it'll only test the kernel and check if it boots.

Thats what I did!

[Q] Wrong boot.img can't connect to computer

So here's the full story.
I wanted to try a new kernel and a new ROM. I was running AOKP so I used the utility for kernel repacks to repack ncx for AOKP. I followed the instructions (wipe cache, flash kernel, install modules) but then I couldn't connect to my computer via USB. So I decided it'd be a good time to try a new ROM and I thought I'd be able to flash the boot.img for that ROM so I went back to recovery and flashed the ROM, but when I went to bootloader to try and flash the boot.img (with OneX one click) my phone did not appear to be connected. I rebooted the phone and to my surprise it booted just fine, even though it has the wrong kernel. Problem is I still can't connect via USB to flash a proper kernel.
Rebooted PC and it's working now

[SOLVED] Phone bootlooping (R800a, 3.01 Turbo Kernel)

I was running PACrom perfectly fine, I made a TWRP backup. I was trying to install AOKP 4.2.2 (which appeared to be successfully installed) and now my phone is bootlooping at the "Sony Turbo" logo, or it hangs there. I can't seem to reboot in to TWRP recovery either (power + VOL up at blue led). I tried reflashing the kernel in using fastboot tool but still the same result. Can't figure out what's wrong :/
Have unlocked BL w/o fastboot menu.
EDIT1: I also tried flashing the stock FTF for the R800a (4.0.2.A.0.42), and it's still stuck at the exact same screen (Sony Turbo logo). Which leads me to believe that it did not even flash the stock kernel.
EDIT2: Alright, nothing was working. So I decided to use the Sony PC Companion to "repair" my device. It's working now booting in to the OS (2.3.4), so I'm gonna try reflashing Turbo Kernel 3.1 and see if I still can't boot in to recovery.
EDIT3: Reflashed Turbo Kernel 3.1 successfully using FTF and Flashtool and am back on PACrom

[S-ON][Latest TWRP/4Ext] Urgent...

Hello folks,
Those who are using latest TWRP or 4Ext recovery,Please comment below.Also i want to know which custom rom your on? I do flash roms in every 2-3 days and problem took place i guess somewhere from CM11 nightly 06/12 onwards.
So my question is: Anybody has encountered a problem where flashing latest nightly or any latest build beyond 4.4.3 causes reboot into recovery automatically soon after flashed boot.img and reboot system.
I always prefer Clean wipe, Install rom, Appropriate GApps, Inspiremod Patch, flash boot.img via fastboot.
Also i would like to add,that when i use Musta's CM11 nightly after successfully flashing it and rebooting the device. But nothing comes after typical htc logo and complete blank screen for few seconds and redirects me into TWRP recovery again. Where as If i use any rom made chinese devs like for ex. Mokee Open Source's latest weekly(randomly) it flashes correctly but it stuck at bootanimation.
Yesterday i've tried one more modified version of Musta's 20140622 nightly made by chinese dev, It flashed correctly but hangs up in bootanimation, i couldn't able to see anything beyond that.
Any sort of help will be appreciated.
Thanks.

[Q] My Xplay reboot only in recovery mode by itself

Hi all, I got a problem I can't understand, suddenly my Xplay touchscreen (unlocked bl, Lupus kernel, don't remember which version, and custom rom) stopped works, so I've decided to reboot, it rebooted in recovery mode by itself, I've tried to wipe cache and dalvik, wipe system and flash another rom, flash a newer version of Lupus kernel and a rom, no hopes, it only reboot in recovery mode.
Any help? Thanks.
EDIT: I've just flashed the latest official firmware, but it don't boot, I see the sony ericsson splash screen and nothing happens. I'm a bit worried
EDIT: after a few minutes I've pulled out the battery and restarted, it booted correctly, but touchscreen don't works anymore like before. So I think it's near to be dead...
