Galaxy S2 Unknown Baseband/Product & Hardware Codes

[TomMiezavs]

Howdy!

Been visiting this forum quite a lot recently about the above issue which seems to have affected quite a percentage of S2 bearers.

I've searched closed threads, other forums (e.g xda - developers) & all of you experts claim that it's a ' nv _ data. bin'

I've followed instructions, countless times. Performed a stock firmware flash (my phone was open to any simcard but as I'm using a '3' SIM I flashed it to a 3 firmware, before this, I flashed to a stock UK/Ireland firmware from sammobile, either process didn't result in my phone working again!

I'm not sure how this happened? It was working without ANY issues & one day my battery drained... as it does and when turning it back on I get a 'stop sign' looking symbol by the clock. I get null / null when performing *#06#, unknown baseband etc, etc.

I've tried my hand at restoring my EFS which I backed up before performing any moderations like rooting, re-flashing, deleting my nv_ data. bin file through root explorer. I've even tried fixing it via EFS Professional which reports that everything is a success... but nope. Still no baseband. I've performed this on both firmwares... the branded firmware (3) & the open firmware (UK/Ireland)

I'm at the end of my tether. The phone was £110 & I've moved cities since purchasing the phone, although I do have the receipt if I ever visit the place again.

What would you guys recommend? I've got a 'device info' from EFS Professional which is copied in this thread. Thanks in advance for any help & advice & please, do not copy and paste forum/link threads stating the obvious like 'its been resolved here, check it out, thread closed' because I would have already checked it out. Hence my post here.

Would really like some help with this... the better half is cruising around the world and with no phone and just over a tenner in my bank I can't really afford another one!

Sorry for being so inpatient
