Just got an E10a off eBay and PC Companion would only update it to 2.0.1.A.0.47. I think I need 2.1.1 and a specific baseband to flash CM, but I can't use a E10i 2.1.1 FTF or I will lose the 3G connection.

I just wanted to verify, from my reading here, that if I wanted to flash miniCM10 I should flash chavito's E10a rom with the appropriate baseband (http://forum.xda-developers.com/show....php?t=1294579) then unlock the bootloader and flash after that?

Yes, and make sure your phone isn't locked to a provider, the bootloader unlock may disable the entire radiochip (2G/3G). You can unlock the bootloader, boot into the ROM and see if you get signal, if you don't you have to lock the bootloader again.

(If you play with flashtool, DELETE the10blrelock.ftf from the flashtool/firmware folder, it will hardbrick your phone if flashed accidentally)

Thanks for the quick reply! Carrier unlocking is the other question I have. I've tried a couple of places to get the IMEI-based unlock code, but none of them can find it. So I'm thinking of getting a USB unlock from this place:

https://www.fastgsm.com/en/sonyerics...ashing-debrand

It says that it will carrier unlock AND unlock the bootloader as well. So I should use that unlock service after I flash chavito's ROM but before I flash miniCM10?

I don't know if your phone is locked to a provider, or which one if it is. The site you refer to says it can only do it for a limited number of countries and providers, but it don't list which ones up front, so be careful with that. If sim-cards from different providers work on your phone, just skip that and unlock the bootloader using flashtool. But yes, you should first flash that latest firmware before you unlock the bootloader.
