Hi Saturn. Since you are very knowledgeable when it comes to our beloved N900, I don't suppose you know of any solutions other than reflashing for rectifying a reboot loop caused by 'messing' with the transitions.ini?
I have previously edited the file without issue but earlier today, things didn't quite go as normal and my N900 is now stuck in the dreaded reboot loop. I updated to the latest CSSU yesterday and have theme customiser installed (but not used - fast transitions not activated). I had been using my own customised transitions file previously, but allowed CSSU to replace it with the latest CSSU version. I didn't like it as much so copied back my custom transitions file (as I did with the last CSSU update, without problem). Upon restarting my phone, my reboot loop began!

Any advice you can offer to correct the problem without reflashing would be greatly appreciated. I did do a standard backup with the Nokia utility before updating CSSU yesterday, but my previous experiences restoring backups previously have been disappointing - conversations missing, all apps need redownloading/installing etc, so would rather avoid a reflash/restore from backup if at all possible.

I thank you in advance for any advice you can offer.

Kind Regards,
Matt
