Thanks quick Reply.........
I am download Jellybean 4part og fireware
I am Downgrade KitKat to Jellybean
N750 100% On, working good
But Baseband unknown
I Have Original N750 Cert File(Other working mobile)
Then
Any Idea To Write Cert File Without UART Cable Or With UART cable

And N750 Mobile Battery 4pin Close Battery pin use tape?
http://i.imgur.com/wfV60I2l.jpg

And Tell UART Cable communication secret Codes(Samsung Note 3 Neo LTE N750)
Please Reply Fast....

[allumts]

Hi, what you do?

I am download Jellybean 4part og fireware
I am Downgrade KitKat to Jellybean

You are been VERY LUCKY, never Downgrade from KK to JB...Brick you device!!!!!

But Baseband unknown

Not has Solved Nothingh, phone always w/o Baseband.

I Have Original N750 Cert File(Other working mobile)
Then
Any Idea To Write Cert File Without UART Cable Or With UART cable

What you think of do with Cert file?...Nothingh.

How would you write useless Cert file with UART cable W/O MODEM side?...or also in USB?..you are totally Wrong!!!

And N750 Mobile Battery 4pin Close Battery pin use tape?

This is ONLY for NEW phone as Note4 (N910/15 series), sometime for S5 series...you phone is Old model no need any of this.

And Tell UART Cable communication secret Codes

No there's ANY "SECRET CODES"...for use one easy UART CABLE.

At this point (also i not have phone in my handles), phone not BRICKED after Downgrade from KK to JB....for me is HW problem.

Can be you Baseband chip is damaged or other HW problem...not try more if first not repair, (if are able), MODEM issue.

N750 is one easy phone and if have accepted also Dowgrade from KK w/o brick...(not have seen any LOG), 90% is HW problem, have only one 10% that can repair via Sw but as i see you not have enough knowledge in this field....

so put Good in you MIND that until you phone Show "SW UNKNOWN" you cannot do Nothingh in this phone like Unlock, Repair Imei itc...IT'S all.
