Sorry for cross posting at D-Ultimate Unlocker - CID53 to CID52 - Top Sony Forums but somehow I didn't see this forum at the time!

Anyway, here is my question.



I have the following phones (OTP/EROM verified by XS++ 3.1)

K810i OTP=CID51 EROM=CID53 RED
K770i OTP=CID51 EROM=CID53 RED
DCU-60 USB cable

Can I use the D-Ultimate Unlocker software with my DCU-60 USB cable to downgrade both phones from CID53 to CID52 to end up with

K810i OTP=CID51 EROM=CID52 RED
K770i OTP=CID51 EROM=CID52 RED

It seems that their website says it can but I have seen others report that their software leaves the phones as BLUE. I really need the phones as RED.

Once I have downgraded I will be able to use XS++ to read/write the FS in the phones. This is why I want to downgrade as I can't do that with CID53.

How many credits do I need? I think I might just need one supreme credit for 20 euros (3 unlocks) which will leave me with the ability to do a 3rd phone at a later date. Am I correct?

Thanks
Darren
