Kernel reset problem

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][HELP!] Arc S won't boot into recovery

Hey.
Just rooted an Arc S via Eroot, installed Rom manager and CWM and booted into recovery via Rom manager.
I then wiped everything (data/cache/dalvik) and installed SuperJellyBean Rom + Arc S Update + Gapps. I then wanted to reboot the phone, but I'm stuck at the bootscreen.
I googled and searched the forums, but I have no luck. No Key combination would work (Menu + Power gets that little light flashig blue briefly, but that's all) I'm always stuck with the "Sony Ericsson" boot logo.
Can anyone help? :crying:

Did you flash the correct kernel for SJB?
僕のLT18iから送られてきた

Bootloader was obviously still locked :angel:I unlocked it via Fastboot, and also flashed a new kernel (Fusion 5.4) that has CWM included.
Now I'm stuck with the Fusion boot logo :victory: Any more ideas what to do?
Is there anyway of flashing a *.zip rom via USB (Flash mode = Back button + Cable)?
EDIT: Finally solved it, though i admittedly don't really know how. Just wanted to plug the phone back into the USB in fastboot mode (menu button + cable) and suddenly i was in the CWM. I re-flashed the Rom, Patch, and gapps and everything works perfectly now.

[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...

[Q] Cant flash custom kernel

Hi, im trying to flash the perseus alpha 3.36 kernel but for some reason whenever I try to install it I get a black screen on boot, or boot loop on device name logo, to fix it i simply load up my nandroid backup.
I've tried installing it via odin:
Once it finishes installing it says Pass with a green background but when it resets , bootloop/blackscreen
I've tried installing it via twrp using a kernel changer from the assassin ressurection custom rom thread.
Oh and 1 important detail: I'm using stock rom (rooted)
I did check see someone saying they got it to work on there phone using a stock rom, so why cant I?
ThanQ

after flashing and the bootloop / black screen can you still get to recovery ?
i copped this a few times when i first had android on my i9000 turned out although designed for my phone the phone didnt like it, and had to use a different kernel.
if you can get into recovery try flashing it again
or get to d/l mode then with adb
adb reboot recovery

No more recovery or fastboot.

My device is an Xperia Xa1 Ultra G3223.
Long story short, I was on rooted Android 7.0 with magisk v16 or 17 don't remember and TWRP. I was unable to update my firmware using the system so I used XperiFirm to get the latest firmware from my carrier. I used flashtools to built a .ftf for branding I wrote Sony and version I put 48.1.A.2.101. I did a factory reset then flashed it.
Now I can boot into android no problem but if I try to enter recovery it just reboots into android using adb reboot recovery. And if I try to use adb reboot-bootloader it just boot loops and the only way I can get out of it is to hold vol down to enter flash mode and reflash my .ftf. I tried using flashtool to enter fastboot but it still boot loops.
Now I'm at a loss for what to do. I was going to try and flash a kernel and recovery from another thread here but I cant do that. Is there a way to flash a kernel/recovery without fastboot or something ?
Thank for any help

Ok well i finally got it working again! I tried using Emma and that updated me to 116 but i was unable to get to the bootloader. Funny enough i unplugged my phone from the usb hub i was using and plugged it directly to my pc i was able to get to the bootloader. So i re flashed 101 and then flash a kernel and a recovery and all is good now no more bootloop when i try to go into the bootloader.
