return to official rom - Sony Ericsson Xperia Neo, Pro

So I had this rom (http://forum.xda-developers.com/showthread.php?t=1876792) and i wanted to go back to my official rom. I went to CDW wiped out system, date, ect etc and I tried to restore my backup which I did with my CWM before I use the custom rom. Everything ok but when I reboot me device it shows the bootlogo of the custom firmware and not the sony and after that it goes black. How do I solve this? I searched but I didnt find anything

Please be more exact on what you wiped and formatted all. What kernel and cwm version are you using? Did you made the nand backup with the same cwm version?

And you flashed back stock (based) kernel?

When you flash .ftf rom using a flashtool, it flashes all official components (rom, kernel, baseband) by default. I apologize flashtool is a most useful method to go back at stock rom. What do you think?

Download flashtool. Download ftf of firmware u want to flash. Open flashtool and drop that downloaded ftf file in flashtool window. Then check no final verification. Click ok. Then follow instructions given by flashtool. Done. Simple as that.

And be careful with device drivers. Install it from a Flashtool folder to avoid a flashing problems.

One last thing, as I said in my first post before i go to jelly bean i made a back up using CWM(The backup was on official ICS 4.0.4 + rooted + BL open). If I want to go back at that backup the only thing i need to do is go to CWM, delete system, delete data, detete etc etc and I do the restore?
Or I need first to flash a kernel for ICS and THEN restore the backup? Im still kinda confused with the kernel thing and the restoration...

Yea. Cwm doesn't reatore kernel. Just the system, data dalvik etc.
You'll need an ics kernel like alliance or suave to boot into the restored backup.

So that was the problem. I can use any ICS kernel or the official kernel( because the backup was on the official rom even though it was rooted) ???

I recommend you to flash a kernel that has been used at time you created a backup, because I had a problems with Wi-Fi when I do «hot-flashing« from suave kernel to night - elf.

If I format system will it delete the backup?
Also If I install stock kernel back from custom kernel then do I have to install CWM again?

The backup stays on the memory stick so copy it in your pc in case something happen
No you will still have cwm

If you used cwm from kernel, then yes, after you flash stock kernel, you will need to instal cwm to system.

From where?
I highly doubt that someone with custom kernel would go and install cwm in system.
