[XPERIA X10 General] sclip:
I have this exact same problem; just replace "ROM 30.7" with "v32". I am pretty sure that I have a locked bootloader which cannot be unlocked without using SETool2 because s1tool says "NOT RECOGNIZED SIMLOCK CERTIFICATE". I have tried the following techniques:

Install kernel, ROM and kernel (all without rebooting out of CWM5), then reboot and get stuck on SE logo

Install kernel, reboot twice, install ROM, reboot and get stuck on SE logo

Install ROM, reboot and get stuck on the SE logo

jlcunff: Have you figured out how to fix your issue? I didn't see any more substantial posts on your problem.

The following information is from the 'System Information' page of the v32 ROM AROMA installer:

EDIT: So for the 5th time, I tried doing everything again from scratch, and I payed closer attention. I see that during rooting (SuperUser; through Flashtool 0.9.13), the log gets stuck at "Running installftkit as root thru sysrun". The log is produced in its entirety below:

Is this a problem event? Maybe the rooting process is not fully completed?
