random reboots - T-Mobile Samsung Galaxy S II SGH-T989

im currently using the juggernaut rom with faux's kernel. i just had my 5th reboot in 3 days now. what could be the problem? not much apps installed, didnt underclock or overclock with any cpu apps......i really dont know what to do.

also can i flash another kernel over the old one without going back to stock first?

Yeah, just flash the kernel in recovery and wipe both caches and fix permissions before and after flashing the kernel.

It's cache related.

You wiped cache and dalvik, then flashed?
Yes, always end up in a bootloop

Try this:
-boot into your rom, backup all your apps, home screen, ect
-boot into recovery, do a complete wipe, flash your rom, boot into the rom
-boot back into recovery, wipe cache, dalvik, then flash kernel, reboot.
You're also flashing an aosp kernel for an aosp rom, and sense kernel on sense rom, not mixing them?
There's one time I manage to flash taimat sbc on sense the only problem it made graphic flickering so I restore back to stock kernel. The was it after that i can't even flash any kernel.

That's your problem right there. Tiamat is an AOSP kernel and you're flashing in on a SENSE rom; its not gona work. If you want to you use Tiamat, you need to be on an AOSP rom, like CM7, Evervol, Salvage Mod, ect. For Sense, try the netarchy kernels.
Netarchy tried that too same problem.

What recovery are you using? It sounds like something isn't getting properly wiped. When you flashed to a new rom, did you happen to try using Calkulin's Format all.zip? It certainly wouldn't hurt. Then get the new rom flashed and booted, then try wiping cache and dalvik cache again, then reflash your kernel. What kernel are you trying to use and on which rom? Perhaps the kernel has major undervolting and you're phone doesn't agree with it, which is not uncommon. There are options with netarchy kernels to use more, less, or no undervolting. With aosp kernels, there are some scripts you can use to change/alter the undervolting, to adjust it to where your phone is stable. So I guess that it's either because something isn't wiping properly, or because your phone doesn't like to be undervolted, or doesn't play nice with HAVS.

Random hot boots

Well as a few days after flashing wicked rom, I keep getting random HOT boots, no boot animation, and reboots behave the same as hot boots, no animation, just black screen then its on. I reflashed rom, kernel, but did not wipe yet. I may soon, but ill wait until I get a better answer. Also I did not overclock or undervolt.

Sounds like a kernel issue. Have you tried using an alternate kernel? And always wipe cache and dalvik cache after flashing a kernel

What rom did you have before? You're saying that you didn't wipe the first time you flashed Wicked? Always wipe before reporting issues that nobody else is reporting. More than likely that is your reason.
Did you flash a different kernel? If so, did you wipe both caches before flashing?

[Q] Flashing Custom Kernel... help...

Is it possible to flash a custom kernel like Trinity to my Gnex stock 4.2.2 rom without wiping?

Unlocked bootloader is needed to run a custom kernel. Root is needed to tinker with and make proper use of said kernel unless you wanna run the stock values. And really, what's the fun in that? Since (if I remember correctly) unlocking your boot loader requires a wipe, then no I don't think you can. But considering most of us have probably done fresh installs literally hundreds on times, I can tell you it doesn't take long at all to set your device back up. Just do it.
My Gnex has unlocked and rooted already, so I can just flash without doing any wiping, right?

I dont run the script but i do wipe internal sd data cache system and pre partitions. I have also tried various recoveries and still happens, its somehow kernel related, it always happens with latest perseus, but today it happened with sotmax and neak kernel, once i had it working i reflashed sotmax again with neak (full wipe) and camera failed. Again i can easily fix this by flashin stock or older perseus reboot to system check the camera and then flash what i want

Yup, first time it happened i freaked out because phone was 1 day old and i have spent one afternon trying to solve this.
I asked in perseus thread and i was only one with this problem, Googling only gavr me answers like "clean cache of camera app and rma the phone"

Hmm...really no idea since im not the pro.
Why dont you try to reflash stock rom thru pc odin and see what happen? If the problem still exists then you can claim your warranty.

If you flashed the latest Samsung Touchwiz 4.2.2 UVUAMDL stock firmware and replaced
the kernel with a modified or custom one then you are surely going to loose root access
and you will need to re-root the phone.
Good luck!

Generally speaking, flash, clear both caches and reboot. Some say fix permissions also. Either way should work.
