First I would like to apologize if this has already been answered. but i didn't find it!
So I have a Samsung GT-N7000 Galaxy Note running the JB 4.1.2 Rooted.
When i upgraded it from ICS to Samsung JB update, it went Network lock.. I Googled the Issue and Solved it with the help of some Galaxyunlock.apk thing..
That night i came to know high pitched screeching coming through my speakers when i play anything (Video,Music even during calls), I thought that it's speaker's fault, I Plugged in Earphones, they also produced that noise.blah blah blah
IN SHORT: My Note's Sound system gone mad ..
It was rooted by somebody, I know about rooting but i haven't done it yet, I've never flashed roms, i did nothing because i can't afford it to brick!
But Now Situation is Different,
I want to get my ICS Back
.So I decided to downgrade to the latest ICS ROM , and, I found Baseband Version is N7000XXLSO.
My Phone is Rooted..
I want to get ICS back because i think it may fix it!
Please give me the step by step instruction to downgrade it (Using Odin or Any thing)..
Thanks in Advance!!
