What kernel did you flash, CM have their own set of kernels and using the stock kernel with CM will cause boot-loops and this may be your problem! Flash the kernel from the CM package first then reflash the ROM, or if the kernel was the problem then flashing it via flashtool will solve the problem altogether without reflashing the ROM!!
Hit THANKS if I helped!!

What where you trying to flash? If it was the CM kernel, then are you sure that you have unlocked the boot-loader the right way?

Is it a drivers problem?!! Have you installed the fastboot drivers first?

No, no, no!!
You flash the CM10 kernel via fastboot. Boot loop is because you're missing the correct kernel (you still have stock kernel)

miniCm9 3.0.3 not booting.....

Hi,
I just recently unlocked my bootloader and attempted to flash the nAa-ics-004 kernal on my X8.
After booting into ClockworkMod Recovery I wiped and flashed MiniCm9 3.0.3.
Now when I boot, I get stuck on the "nAa" screen and the logo keeps repeating itself but I can still press back to get into recovery.
So how can I boot into minicm9 now?
Ummmm.... help would be nice.
EDIT: I'm a noob, I unlocked with X8Toolbox, flashed with flashtool but flashtool only said "loader.sin is flashing" or whatever it says, should it say both? I did select both loader.sin and kernal.sin using SHIFT.

okay
1. first check your baseband is xxx015 (if not, you can find the baseband from B.jay folder and flash it!)
2. Root your phone
- with flash tool by clicking the padlock icon
OR
- copy these files (password=cintaindonesia) and extract on your SDcard, copy paste to system\bin with rootexplorer
4. then unlock bootloader by s1tool or flashtool (NOT FOR 11w29+ !!!)
5. flash the latest ICS kernel
6. backup
7. factory reset, wipe data, etc
8. flash the ROM
9. Done!
Thanks!
Thanks alot guys for your help! I now got MiniCM9 working! Thanks once again.

have u tried to use SEUS?
we fixed it.
I dont have this phone, so I didnt know you needed to have custom kernel and unlocked baseband.
How can I get the:
1. Latest baseband
2. Unlocked bootloader
to unlock the bootloader you have to check This
for latest baseband update the phone with Update Service

Thank you.
Where can I find this kernels
nAa AND ALFS KERNEL ?
or do they come with the ROM and automatically flash?
you can find in one of the Development Thread, you have to flash it first with flashtool then you can flash the ROM via CWM..
U means u didn't install X recovery.... If u install cwm its possible u having this problem... Cwm only work on stock rom.... Use flash tool and repair.. Install X recovery....i installed it too.. I got the same before, though it was on that Site.. This will work on stock rom

[Q] Problem with CM10.1

I decided to flash CM10.1 the newest stable v.
That is what i do:
1Root the phone [latest official firmware updated via update center]
2Installing CWM
3Going in recovery and make factory reset, wipe cache, wipe dalvik
4Flashing CM zip
5Flashing Gaps zip
6Pressing "reboot now"
And then the phone goes off and that is all. If i hold the power button for ~3sec it vibrate and nothing more. No booting img no error sign no nothing. Cant go in recovery too.
Does anyone have a solution?
I tried it around 5-6 times - black screen all of them.

Please read the instructions for flashing CM ROMs.
It needs an unlocked bootloader.
Repair your phone using pccompanion, or by flashing a stock ftf with flashtool

AFAIK not. CM uses its own custom kernel (hence the unlocked bootloader) and Doomkernel is for stockbased roms

Xperia SP 4.3 by DooMLoRD

Hello. I did all the steps in DooMLoRD's post, but there is something wrong. The phone is freezing all the time and really slow. After this 1 message appears "System UI has stopped" and then it works better, but when i try to start a game... "(name of the game) has stopped". I ask other guys, but they dont have problens like that on this ROM.
Can you tell me why is that? Thanks in advance!
Did you wipe your phone before installing? Try to install the DooMLoRD's rooted kernel and do a wipe in Recovery. Then, install the ROM again.

Is it posible to have that problem if i unlocked the bootloader or root the phone wrong?

As long as your bootloader is unlocked root is not important for flashing this ROM. And if you already managed to install custom kernel (for example for aosp based rom) then you successfully unlocked your bootloader. Maybe as the previous post said, try to install DooMLoRD's kernel (The old one) then reboot recovery, wipe, flash 4.3 zip and it should work

I have installed this one: SP-4.3_leak_256-DooMLoRD_AdvStkKernel-v1 Is that the new one ?
I found this: SP-DooMKernel-v03 and SP-DooMKernel-v04
Is that the older kernels ? Because i try the kernel in the ZIP with the ROM and there is no recovery...
Guys....
Im trying to install leaked 4.3 but have issue
1.flashed .254 using flash tool
2.Rebooted
3.Flashed Advanced kernel via fastboot
4.Rebooted
but when i turn on the phone after that,it vibrates once and then there is no display.
so i flashed .254 stock kernal but that didnt fix the issue
As of now im on .254 stock ROM with bootloader locked again
Please explain me step by step process to get this done with 4.3 plzzz
Please note that my phone even though was c5302 always displayed as c5303 in PC companion but it isnt now.

Okay! Do it this way
Unlock ur Bootloader
Flash stock .254 ftf
Then root and install cwm by locked bootloader method
( by installing previous firmware kernel ftf, root by doomloard kit, install cwm of locked bootloader then flash ur latest. 254 kernel ftf)
Now just flash the 4.3 rom through Cwm without Wiping anything

Of course, cause u havent flashed the rom yet! You only flash the kernel, not the rom.
Now do it exactly as you did before, but after flashing the kernel and rebooting, tap the volume uo button continuously until you boot into cwm. And then you can flash the rom through cwm.
Dont forget to copy the zip in your ext sdcard before flashing the kernel!
Cheers.

[Q] PROBLEM!!! Can't flash anything bellow ics

Hi! I have an lg OB running ics 4.0.4(V30B). The phone it's rooted and I have CWM installed from Rom Manager. I can acces Recovery from Rom Manager and with the phone off ( VOLUME PLUS + G KEY). The problem is that I can't flash any Rom bellow ics (not even with Smart Flash Tools) without getting bootloops. I can flash Roms based on ics and above( IZS,CM10.1,NAMELESS ROM NIGHTLIES 4.4.4).
Could someone help me?

I was hoping you fixed the issue. I don't know what to do.
It's a matter of unlocking the boot loader. Once you do that, you can jump back and forth between ICS-based ROMs and everything else.
Gingerbread ROMs include the boot loader (marvel and Huexxx).

Man I can flash ICS-based ROMs .JB and KK, I can't flash GB stock or GB-based ROMs, not even with SFT.
I think the bootloader it's unlocked because I can acces CWM from switch off phone(key combo)....I am confused because i read many tutorials but they are contradictory
That happends also with me 2 times.
Just flash CWM recovery again.

No, I don't tried to unlock bootloader, but like you , I got the bootloops every time I downgrade from ICS, Nameless or cyanogen roms . I use original Froyo - flashed with SFT , then upgrade to GB with Cwm recovery patch- flashed with SFT, then boot to recovery and install Nameless.

Did you already try the alternative way without the app? Which means load the files to your sdcard and afterwards type the dd if=xxxx of=xxxx? This could show if it works or fails. And did you ever flash the LU5900 port? So the early ICS ROM released by Redy, Gabwerkz and me. Try the manual unlock first.

OK I have the terminal emulator on my phone.
I've read the thread and it says "Move this two files, bootloader and recovery to the root of memory sdcard;
Enter in the command line
su
dd if=/sdcard/u-boot.img of=/dev/block/mmcblk0p2
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p4
And reboot or reboot recovery."
I have downloaded all on my laptop(bootloader recovery and su) but I am confuse....what's with that "su"?
Do I have to put it on the root of the sdcard too?
Sorry for my noob question
