my android ver.4.1.2
baseband last 3 is MD4
my question is how can i fix it do i have to be rooted to flash a diffrent radio

You can use Odin to flash firmware. You just need to find it in the dev section. There's a whole thread for it.

I don't know if you are still looking for this, but everything you need is here

[Q] Update modem/baseband to XXUBMJ7 without KNOX - possible?

hey guys,
i'm just wondering if KNOX comes along when you update modem version to XXUBMJ7 by flashing only NON-HLOS.bin (not the rest of the rom!). Is it safe to do so? Anyone already tested this?
I want to update modem, because reception with my I9195 is really bad...At the moment i have modem version XXUAMH4.
THX for any help!

Nobody tried or has any informations about that???

I can confirm now that flashing modem to newest version is possible without getting Knox

Ah and here is the screenshot...

is the reception better with the new modem?

I think so, but i'm still testing. Perhaps tomorrow i can tell you more

Hey guys I am veeeery new to flashing and stuff so i tried to get baseband I9195XXUBMJ7 on my phone and have I9195XXUCNK1 right now (I think).
I followed a step by step guide on how to use Odin and I had no error messages coming up but when i checked in the system infos it said Baseband: unknown and in an app I got to SimUnlock it said Bootloader: I9195XXUCNK1 (I guess that's my current baseband)
I could really need some help and you seem to really know what to do
Best regards

[Q] baseband unknown, trying to downgrade rom

Hey guys, so I finally decided to go back to a stock rom for the t989 (4.1.2)
i downloaded tiberus for the kernel
uvmc6 stock for the rom via this thread <<is that even a legitimate stock? i'm not sure because that's the only one i could find that doesn't seem to be tampered with.
and uvmc6 for the radio
for some reason, after flashing, everything works great but i have no signal. the baseband in the "about phone" reads "unknown"
I don't know what i did wrong because it seems like I did everything right by getting the same version, kernel and radio for it but it's still not working.
even tried going to an earlier radio but still no success.
can someone tell me if i'm missing a step? did i do something wrong? can i even downgrade (specifically coming from this ROM and i want to go back to stock)

I am facing the exact same issue. Can anyone please share any pointers. Thanks so much.

Not sure about the rom you linked, it's not official stock is about all I can see just from the filename.
If you really want to go back to official stock 4.1.2 ROM, then you need to download either one of these, this is for T-mobile/T989 or this is for Telus/Koodo/T989D
Either of those I linked are flashed through Odin in Download mode. unpack and flash in Odin, If you need a re-fresher on how to use Odin check here, at Step 9 just replace that with the rom you downloaded/unzipped.

[Q] Not registering on Network / Wrong IMEI after flashing stock 4.3

Hi, I have just flashed Rooted Note 2 on 4.3 to the latest stock ROM which I downloaded from the SamMobile and now it will not register on the network.
The new version I flashed was the same as the old as i found it with the CSC N7100BTUEMK2 on sam mobile.
I checked the IMEI and it says 00499010640000 in status menu which is different from the one under the battery.
I did not perform a backup of anything as I was not worried about losing any data.
Any ideas what has happened to it and how to get the IMEI correct again?
I understand this is something to do with an efs file but in what way it has become faulty from flashing the same rom I cannot decipher
Any help much appreciated! :good:

From my experience:
1) Reflash the ROM.
2) Flash a custom ROM.
Both worked for me.
N7105 rocking AOSB with AGNi kernel,
Click "Thanks" if I was of any help!

Thanks, I have reflashed the current 4.3 rom UEMK9 and a slightly older UEMK4 with a DEMJ9 radio.
I have tried lots of radios - DM3, XXDME4, XXMI6, XXMJ5, XXMJ2, and some other modem.bin
From what I understand its when you go from newer to older roms that you get IMEI problems, so its prob useless to try pre 4.3
Its all a bit confusing to me and which rom has which radio seems like an arcane mystery.
It is quite possible that I flashed a same version 4.3 rom but my old radio was different and not knowing it was such a minefield on Galaxy phones I never checked that or bothered with a back up.
I may have to resort to paying the people at unlocksamsung online £26 to reset my IMEI
Can anyone tell me, is it just the radio that causes the IMEI problem and should I just trawl through flashing radio zips until my IMEI comes back so I can save the efs file?
BTY everything else seems ok SN is correct and wifi works fine, I just can't get on a network without my correct IMEI
Thx

i also have the same issue on my note 2 gt-n7100 and now phone does no respond to the touch post rooting and all..i am tired of rooting and unrooting the phone like 100 times allready and now my phone is stuck in loop
