My o2x won't boot when I apply a oc/uv kernel

Hi all
I possess one o2x at present there 1035.21_20110218 on mckr12 Roma fr16 beta 4.
I noticed that when I flash a capable kernel oc / uv, my phone stuck on the log's logo...
Anybody has already met this problem?
Thanx
No but if you reflash the rom it will remove the new kernal and put the original one back on and you will keep all your apps etc aswell
I have this problem too, i flash the new Fr17 & Fr18 mcr can't boot. If i just flash the older Fr16 kernel, it booted...............
soo. no way to have a uc/uv kernel on my o2xs ? :'(
If you flash vork then it won't work cause it was meant for CM7
just reflash back the ROM in recovery
Back to Stock Rom.
Try to back to stock rom as said dusitmon123, then Wipe everything, and reinstalling custom rom will work...

[Q] Installing custom kernel = boot loop

Hello, when i try to install custom kernel i face a boot loop. I only tried with v10, not tried with v20 though. Tried 3 different kernels and the same. Why is that? It just doesn't work.
And can you tell me some working custom kernel for v20l to try?
Thanks in advance.
What rom are you using?
For myself, usually its an issue of partition beinh ext3 or ext4 that will cause bootloop. I will usually try back2ext3 from paul or ext4 converter.. either one usually fix the bootloop depending on kernel requirements.
Cheers!
Not enough details. Which kernel?
On total stock ROM or on custom stock based ROM?
We are talking about kernel do don't use what is mentioned just above, it will wipe your all system.
I had a boot loop problem after installing a custom ROM based on stock ROM. I didn't wipe the phone before updating to custom ROM. After recovering the original ROM, I wiped the phone from CWM and then updated it and all works well now.
Well i have tried Neoblaze, HorsePower, Spica. I don't wipe after/before installing.
I om on stock rom. Then i must go back with back2ext3.

After installing the kernel try wiping cache and dalvik and see if that helps.
that's your problem, you have to wipe cache and dalvick cache after flashing. hope this can help
Thanks you, im very happy - working now. Flashed HorsePower.
Does Flashing a Custom Kernal Using Orange Fox Recovery Leads to Bootloop ?

[Q] Flashing ICS Roms when you are already on ICS

Hello guys!
I was wondering how should I go about flashing another ICS Rom. I am already on AOKP build 23. If I want to flash another rom do I just wipe data, cache and dalvik cache and install from SD card?
Also, to change a kernel do I just install from SD card?
Many thanks!!
its no difficult man
Just reading. No so difficult like he said.
erm, so is what i said correct?
Factory reset (which is the same as wipe) -> install from SD. Done.
Yes, you got it right. Also follow instruction for the specific rom you want to use.
If there are problems flash to stock with odin + repartition.
Restore and flash
I tried to flash slim rom from sharing rc 4.2.but failed to pass the kernel screen. Don't know what went wrong

Flashing from one custom firmware to another

Hello guys,
actually I've darkysrom with darky kernel on my SGS but I want to change to another custom firmware, mainly because of ICS.
Can I flash the new cfw just by using clockworkmod? Because I remember that there was something concerning the kernel which was important before flashing to another cfw.
Do I have to disable the lagfix before flashing?
Yes you must disable lagfix to avoid problems with the new kernel.

Do I have to seperately flash another kernel or is that been done by flashing the cfw?
Disable lagfix, wipe (data, cache, daliv cache), Flash ROM via CWM, flash new kernel. If it gives you bootloop go to CWM and flash kernel again. It should work ;-)
Hi,
i tried to flash slim ics but something wrong happened. first i opened clockwork recovery and wiped everything. after that i tried to install from zip and choosed the base file of ics slim rom but there came a message which said that the installation was aborted. then i've read in the tutorial that one has to format the system but it still didnt work.
now the phone doesnt boot anymore but i can get to clockwork recovery. i recognized that it is a modificated version from darky with the name "cwm darkycore recovery" or something like that.
can someone please help?
EDIT:
ok the phone is back alive. i flashed darkyrom with odin.
but i guess the same will happen if i try to flash slim ics again so there must be another way right?
EDIT2:
i got it. just installed the cm9 with cwm darky core recovery and after that installed slim ics.
if you've got to the trouble of odin-flashing the darkyrom back ,why didnt you just flash something else ?

[Q] Few questions about Roms, flashing and Kernels

Hi guys. I just decided to use custom Roms because stock is slow. I checked some Roms and 2 interested me: CM 11 and Zaiben.
1. Could you tell me about differences between them? At the moment I have got orginal Android 4.1.2 V20B. Is it possible to flash Zaiben from V20B, I am asking because in Zaiben's thread there isn't any information about flash from v20b. There is only about flash from v20a. And I can't post in that thread yet.
2. Also what should I do before flash new Rom. Will wipe data/factory reset and wipe cache partition be enough?
3. And could you tell me if I want to flash new Kernel I just use install zip option? And which Kernels do you recommend guys?
Thanks in advance.

1) Zaiben is a modified stock rom, cm is a completely independent rom based on open source project.
All you need to do is have the most updated recovery and you can simply flash right away.
2) If moving to zaiben you can probably dirty flash and don't need to wipe data since it's basically the same basis
If moving to cm you will most likely need a full wipe (system, data cache and dalvik
3) Yes - you canno't ask that question
Before you do any of the above you must unlock your bootloader to install cwm or twrp recovery!
Thank you for the help And last question: If I change Kernel what do I need to wipe after this?

Flashing kernel doesn't require wiping anything.
Each kernel has it's advantages and disadvantages. You need to read through their topics and find out which one will be more suitable for your needs.
Then I will try some. Thank you for help
