[P1i] Restart loop after putting too big fonts for FontRouter

So, here is the thing - I was just looking for some fonts that look nice and I replaced the system fonts successfully, until I put a font that is just a bit too big to fit in text buffer and when I restarted the phone (executed Z:\Sys\bin\EStart.exe) it went to restart itself and not being able to turn on again. I've spent all evening and night trying to find a solution on the internet, and I need to delete one file in internal memory of the phone, but I can't do that... So only thing left to do is to reflash the ROFS, but I can't do that because SEUS does not work anymore and Sony does not provide P1i flash files anymore... :(

Ones I found apparently had wrong header or were corrupted files. (Used XS++ 3.1) Can anyone please help me or can anyone please at least give me the flash files for this phone? (R9K009, R6G05)

Thank you for any support! :)
