[Q] Help - Defy is stuck in bootloop

[syddd]

Hello

I've tried to upgrade my Defy (525, green lens) to CM10(jelly bean), but im stuck in a boot loop!

My phone had originally Android 2.1 installed, one year ago i successfully rooted it and Android 2.2 successfully.

What i've tried:
- load into 2nd init, wipe cache/wipe data
- install kernel-froyo-222-179-4-signed
- install CM10-20120924-NIGHTLY-mb525
- wipe dalvik cache(this does not promp for confirm, and prints nothing to the console, is this normal?), wipe data
- reboot. Now its stuck in an endless boot loop.

I can enter bootmenu/bootloader/2nd init/stable recovery. I can share here the SD card, so i can copy stuff to my phone
But as i turn on the phone, the red moto logo appears, the top LED is blue, then green, then reboot.

Did i miss something? (I've read somewhere about flashing SBF, do i need to do it?)

EDIT: I've tried to install cm-7-20120930-NIGHTLY-jordan.zip, but this gets stuck at the moto logo forever...Can i someohw see the bootlogs to fund out the problem?

Thanks

EDIT2: Solved it!

1. installed back Nordic froyo with RSD lite, rooted again
2. instaaled CM7 with this tut: http://forum.xda-developers.com/showthread.php?t=1054447
3. installed CM10 with the instructions from here: http://forum.xda-developers.com/showthread.php?t=1795647

dunno what went wrong for the 1st time, maybe upgrading from 2.2->4.1 does not work...

What went wrong

You have answered yourself. In the link to install Cm10, you will see the instruction requires you to flash froyo kernel.

For MB525 builds:
1) Go to Stable Recovery.
2) Wipe data/factory reset, wipe Cache and go to Advanced ► Wipe dalvik.
3) Go to install zip from sdcard ► Choose zip from sd card.
4) Flash froyo kernel
5) Flash CM10-2012xxxx-NIGHTLY-mb525.zip.
6) Flash Gapps.
7) Wipe Cache and Dalvik again (recommended).
8) Restart.
