[Q] About kernels and basebands

I've searched the forums but to no avail, so I'll just ask this here. I'm interested in changing the ROM of my Xperia X8 (E15a). With S1Tool I checked whether I could unlock the bootloader of my device, however the certificate is not recognized so that's a no-go for me. For this reason I'm stuck with stock kernels only.
Here is my device info:
Code:
Model number: E15a
Firmware version: 2.1-update1
Baseband version: M76XX-TSNCJOLYM-53404006
Kernel version: 2.6.29 [email protected] #1
Compilation number: 2.0.1.A.0.47
Here's when it gets confusing. All the ROMS I find here on xda say that I should use a baseband that ends in 015 and if I don't have that baseband, I should update with PC Companion to the latest one. PC Companion says that my device is already up to date, so I can't get another baseband. So I thought of trying flashing with FlashTools a baseband that actually ends with 015. However I read that that basebands work with specific kernels, so my best guess is that I should find a baseband for kernel 2.6.29, right? Well, I'm out of luck cause I can't seem to find that thing.
So, basically the question is: How do kernels and basebands are related and what should I do if for instance I want to install this ROM: http://forum.xda-developers.com/showthread.php?t=1079463... should I flash a older kernel for which a baseband with 015 does exists or what?
Thanks in advance

GT I9305 Android 4.3 RO Orange how to root?

Hello to all.
I have a GT I9305 with Android 4.3 from carrier Orange country RO, I need help in rooting my phone, I want to put the S5 project on my S3 smartphone.
For the beginning I have done some research on the forum and found some related topics but I'm stuck. I want root so I can back-up my efs partition so I'll not lose my IMEI.
The steps that I fallowed are:
Read topic : http://forum.xda-developers.com/galaxy-s3/help/frequently-questions-t2148708 and http://forum.xda-developers.com/galaxy-s3/general/howto-rooting-wiping-flashing-ultimate-t1911726
Tried Safe root, but it fails with msg: Kernel patched!
Read about CF-Root but I don't understand all the codes from the list, wich one to use? Is the one from the GTI9305 appropriate for me, hope will not break my phone, or is just for the international GTI9305?
Model: GT I9305
The base-band version is: I9305XXUEMK1
Android: 4.3
Kernel 3.0.31-2051278
Can I obtain root on this smartphone? Thank you in advance.

I have a GT-I9305 Orange device which was on 4.3

flashtool showing different imei, imei unknown issue.

hi guys, i want to ask something, i am having serious issue here! my phone was running android 4.1.2 but having no imei and unknown baseband. some thread stating if i was downgrading my fw, i will be having lost imei and unknown baseband issue, but in my case, the only fw that working was just android 4.1.2, and in my country, my phone was supposedly running on android 4.3. but when i am trying to install stock fw, i got a bootloop state. i have tried different method as such using xperifirm to download stock fw and updated fw, using pcc, but still suck in bootloop.
and my another question was, when i tried to relock my bl, flashtool showing different imei for my phone.
