[Q] Flashing Baseband from 4.1 on 4.3 - Xperia SP Q&A, Help & Troubleshooting

Hi all,
I want to know that, can I flash only the baseband form 4.1.4 stock ftf on my current 4.3? Is there any conflict with 4.1 baseband with 4.3 OS?
Please help me guys :good:
Thank you all! :laugh:

Pls someone can answer that??

I think you can't do that,because every firmware has its own baseband... if I'm correct...

are you sure you can downgrade "knox'ed" 4.3 firmware to 4.1?
all users that have tried simple odin flash report that odin gets stuck at flashing and your knox flag gets tripped
for the moment you can't go back to 4.1....that knox bootloader won't let you...

[Q] How can I downgrade from 4.3 to 4.1 ?

Hello, I`m new here. I got xperia sp c5303, android 4.3, build nr 12.1.A.1.201. The phone is almost one month old, I`m from Romania and I bought it from Emag. My question is this, if I want to downgrade what version of ftf should I download? After i make the downgrade is there anyother update I should be aware of? My phone was running smooth before the update to 4.3,now it`s just laggy.
Please guide me if you can since I`m noob and have no ideea what I`m suppose to do.
thank you in advance.
