[Xperia Play Q&A, Help & Troubleshooting] DanielEGVi:
So... here's the sad story:

I finally got my new supah Xperia Play R800i. I was a very, very happy user. It replaced my old iPhone, and when I wanted to play some games, this thing was ultimate entertainment. I installed a lot of customization, LOTS. Installed GO Launcher Ex, Widget Locker, Multitasking Pro and much other stuffs as well as games like Battlefield BC2 and Dead Space. All of that took DAYS of downloading, installing and configuring.

Ok, let's skip that part, I know nobody cares. After a while I did some research about the Xperia Play, and found this awesome forum. Then I learned about rooting and why root. I grabbed a copy of ZergRush and rooted my phone in less than 30 seconds. Awesome experience, installed Tom Toolbox and Titanium Backup, which I only used to erase Chinese applications that come preinstalled. The phone was customized to the Max.

A few days later I found about the unlocked bootloader and about the flashing business, I decided I would change to CM7 for the good stuff, I went to SE Bootloader Unlock Page and followed all the steps. I needed fastboot, which Google forgot to include in Android SDK Tools rev 15 and it took me a while to figure out how to download rev 13, but I finally did it by copying the link of the rev 15 zip and pointing it to rev 13. Then I learned what is fastboot and how does it work. Then I finally unlocked it.

It formatted my flash drive. All the stuff. EVERYTHING. And silly me I forgot to use titanium backup. I decided not to regret, yet. Then just when I was about to flash CM7, I broke the number 1 rule when unlocking bootloader: OTA UPDATES. It bricked my phone. But I didn't panic much because I knew that if you brick your phone with OTA updates and unlocked bootloader, you just lock it again, simple as that. Found this Blagus' relock bootloader script on the forums and applied it, but I accidentally flashed UK Stock firmware before doing it. Didn't know if that would cause any problems, but, the only thing AI noticed is it didn't have the TV Tube Sleep Lock Animation and other non-important things. Then I flashed CWM recovery and wiped my phone (yet again) to install CM 7.1.0.2, when it finished, I installed Gapps and rebooted the phone.

First thing I said was: cool boot loading animation. Then once booted it took me to the setup page. I noticed something: radio isn't working! I immediately went to the about page and it reported: "Baseband Version: Unknown". It isn't a phone if it doesn't include a phone! Camera didn't work, every application I ran just FC'd. I said out loud: "Damnit, I've f****ed up my phone. This is it. All 400 contacts gone, 328 apps gone, hours and hours of gameplay gone. EVERYTHING. Gone. And I had the godd-mn possibility to backup with Titanium Backup." But then I looked at the PC monitor, "There's still hope in there." So I decided to post this.

Sorry for being dramatic, but what can I do to fix the baseband? I've tried with wiping, reinsert Similar Card, what do I do? I also heard about something called "Odin" but I have to much headache to try to figure out what is it, and try to brick my phone again.
