Hi. Sorry for asking similar question. Actually I sold my note 2 to someone. At that time i was using 4.3 test build, he downgraded it to 4.1.2 and now signals won't appear/ no network issue. My guess is that EFS folder has been corrupted (no backup). So should I flash a clean 4.1.2 from odin or try flashing any 4.3 to make it work?
Try to flash MJ5,MJ2 Modem.
I don't remember the test build but try all 4.3 Modems.
If you have EFS backup then restore.
Already moved bck to 4.1.2 so why flash the 4.3 modem?

With the mj5 modem, the phone can read the new path for the efs file. He should try it. Nothing to lose.
Correct me if i'm wrong

Recent stability update is not allowing the flashers to downgrade or limited to only roms with particular modems as it is causing to corrupt the IMEI.
Though our clever developers have found many solutions it has become a hindrance to many of flashoholics like me.
What do you think? Can there be a permanent solution to this? and most important why Sammys have done this. I do not think this is some kind of bug. It is done on purpose,like preventing people from frequenting flashing?
what do you say?
I agree with you, efs problem and partition table corrupt are such problems which make people to think before flashing

I am not flashing any rom for the moment.
Do asop roms suffer from efs problem?
After an update my IMEI has changed from what is under battery cover to something like 004999xxxxxxxxx after which I can't make phone calls any more , after checking I've discovered that the EFS file doesn't contain the IMEI anymore, when happened this my phone was not rooted so obviously I have no backup.I've flashed back the original ROM many times but it's still the same.
Do you think there is a way to find a solution to this?
Please give detailed description of what happened like which was previous rom and which rom you are now on and trying to flash....

Latest update is not allowing the downgrade of modems, so please reflash the nordic rom so that atleast you will have your IMEI back. I was on ARHD 17.0 , tried Omega rom which is DME6 and reverted to ARHD 17.0. In the process I lost IMEI. So I reflashed Omega and I had my IMEI
NOw ARHD 18.0 is also DME6 and I can flash it but not below that
Ok will try it.
Just one question please,do I need CWM installed on my rooted phone to flash a modem?

Hi all,
I'm planning to flash my phone back to 4.1.1 via Odin and then to to 4.1.2 firmware, found on Sammobile to carry out the unlock method.
However, I am on the DMF2 baseband, and have heard that flashing a new modem over this will mess up the IMEI.
Will this happen if I'm only flashing a stock rom over it?
Thanks in advance!
I used to flash 4.1.1 stock ROMs onto my N7100 from 4.1.2
I would go into a bootloop after flashing it but booting to recovery and wiping data and cache solved my problem. Just backup your EFS to be on the safe side though

flashing new modem will not mess up IMEI.
but to be safe, back up your EFS before you do.
Normally IMEI will be messed up if EFS corrupted during the flashing.
Most of the time, it will happened if you change ROM with different base version (and normally happened when you never read the instructions of the OP very well).
So, when you want to downgrade, please do backup your EFS first (especially if you are coming from 4.3, due to different bootloader/partition of internal storage).

I flashed this TW 4.3 last night
http://forum.xda-developers.com/showthread.php?p=48048833#post48048833
And I already miss AOSP smoothness/faster feel. What's the easier way for me to get to any AOSP 4.3
Going thru other threads. It seems, If I try odin back to 4.1.x stock, it may not work/i may brick the phone.
Advise plz
P.S: Currently on I747UCUEMJB MODEM as part of this TW 4.3

Did you flash the mjb (4.3) bootloaders? If you did, you will brick by flashing backwards. If not from what I have read it is relatively safe. There is always a risk of bricking even with the simplest of tasks involving flashing.

NO I did not flash the bootloader. I was on Quantum 4.4 for quite some time.
I am planning to travel abroad in couple months. So, to unlock wanted to try TW ROM. hence picked this one (it didnt work though)
This is what I did from 4.4 quantum
Nandroid backup.
flashed the I747UCUEMJB Modem
wiped everything
flashed the ROM
flashed dkp test kernel for TW 4.3
Reboot.
As i took nandroid backup of 4.4 quantum. Now I wiped everything from this TW 4.3 and restored that backup.
So, currently i am on 4.4 quantum (through nand restore)
But phone baseband version says I747UCUEMJB. that's why i am asking the question here.
Hello I want to back to the stock mod but I already build the kitkat.
Can I go back to stock mod? Please help me!
also I found this rom

but my phone is from at&t, can I install this?
please help me!
That is my Sprint port (StockMod kk) just repackaged for flashing in odin.
To your original question, if updated to kk firmware, you can still run all the roms as before. Just you can only use the 4.4.2 modem. Some 4.3 rom threads say to use the 4.3 modem, but ignore that if updated to the new firmware.
Thank you

Thank you! so I can not use this mod ;(
yesterday I tried to back to stock mod but my phone hard bricked ;(
I tried some of image flash thing so get back to normal phone but still don't have imei or data
*sigh* I have to find fix shop
If you have got the phone booting again you don't need a fix shop. The imei problem is probably due to flashing back to mjb modem. See this thread: http://forum.xda-developers.com/showthread.php?p=53851558

My data still drops on the new 4.4.2 kitkat update on m919. Like always airplane mode solves the problem. Is there a fix for this?

That does not resolve the problem, the problem is the 4.4.2 kitkat and 4.3, Im having that signal issue also, and I have tried other firmwares. I also have a Note 2 and when it runs 4.1.1, this version has no issue. The new firmware with the modem inside it, its what causing it the problem. Your best bet is, as I have posted in a few section is for someone to make a back up copy of the QCN, of the original stock M919V modem file QCN, its very easy to make a backup of the QCN, with that we can reflash it in QSPST and make the AWS work, I need someone here with a videotron s4 model M919V to make a backup copy of the QCN file so we can try it out, if not we need to wait till they release a newer version. My model is the S4 but my model is i337M, but you can flash the M919V firmware because its the same modem inside it, NE1.
