just before i flash,
this is the ouput in XS++ when i let it identify my phone:

09:52:13| Baseband ID: 9900
09:52:13| Protocol Version: 3.1
09:52:13| Warning: IMEI name does not match GDFS name (IMEI:NULL GDFS:K550)
09:52:13| ...using GDFS name

09:52:13| Phone ID: K550

09:52:13| CDA: CDA102295/1 R2A
09:52:13| Firmware Version: R6BC002
09:52:13| EROM: R3A011
09:52:13| Ready for operation!
09:52:20| User chose NOT to update EROM CID!



now you can see that i have a cid52 firmware on a cid51 phone, can i still flash an old cid51 firmware on it ?
another thing, will it be safe to do cid upgrade on this phone via wotanserver ? since the cid and firmware don't match and the phone can't be identified through it's imei. i'm asking about wotan since XS++ doesn't upgrade it and SEUS doesn't upgrade my phone firmware.
