No signal, Imei Null, Baseband Unknow - Galaxy Note II Q&A, Help & Troubleshooting

Good night everybody, a quick resume of whats happening.
today at the morning i noticed (after visiting some usual web-pages) that in the blink of an eye i got No Signal at all, i re-booted the phone and nothing.
after a long day at work, with the same problem i got home and start doing research.
First.
this was my set-up (Sammobile Stock-rom)
Model: GT-N7100
Model name: GALAXY Note II
Country: Brazil
Version: Android 4.4.2
Changelist: N/A
Build date: Thu, 01 Jan 1970 00:00:00 +0000
Product Code: ZTO
PDA: N7100UBUFND2
CSC: N7100ZTOFND2
MODEM: N7100UBFND2
as you can see, not fancy at all, no root, just trying to get a better signal of where i live(argentina).
now, i tried flashing the same rom again(ODIN,after full wipe of course), differents roms(using TWRP), i tried using a rooted rom and replace my efs folder with a backup that i have(i think this didn't work out 'cause the efs backup is from 4.3 stock and now im in 4.4.2 stock)
i have no SIGNAL, baseband always UNKNOWN, and IMEN null/null.
i still have warranty, but the only way to recognise them is having the companys rom, wich in this case is 4.3 sooo, as right now, i can't flash it and fix it by warranty, just wait or keep trying to fix it, i still don't get how this happened, from a second to another.
Any help will be really apreciated.
Thanks!!!

The baseband is broken. You need to go to a technical store to fix.

Visit this thread http://forum.xda-developers.com/showpost.php?p=48011830&postcount=23 and download the modem and flash it via recovery.See if this helps in restoring your IMEI baseband and network signal.If that doesn't help check out this patched modem and flash it via recovery https://www.dropbox.com/s/kgffgmzej3shhr7/nb4_N7100_Patched Modem_CWM.zip (to flash both zip one needs to be rooted and on custom recovery) Good luck

search for "i9505 Firmware 4.4.2 z3x". see if it help

Oi, não sei se vai ajudar, mas eu estava com o imei de final 640000 e após tentar o que singhpratik87 falou, eu tentei restaurar o IMEI baseband e network sinal através da troca do modem, mas acabou que meu imei mudou de maldito para null\null. Mas após eu tentar o outro link, o imei saiu de null\null e voltou para 640000. Então em resumo, pode ser mais fácil para você resolver o imei maldito ao invés de resolver o imei null.

[Q] n7100 N7100XXUEMK9 no IMEI odin FAIL KNOX activated

Hi everyone,
I am tried to recuperate a Samsung note 2 GT-N7100 without efs backup and baseband, imei and network lost. KNOX is activated.
Following to "Originally Posted by dr.ketan View Post N7100XXUEMJ5 How to Root + Remove New Bootloader + KNOX Free" from "dr.ketan" I really hope that I can do it. But in the first steep I´m blocked, because when I try to flash "PDA: N7100XXUEMJ5" in the first second appears "FAIL" and the phone said "that is not compatible with this version".
To download the original rom from sammovile like dr-ketan said linking to "http://forum.xda-developers.com/showthread.php?t=2499794" of "Faryaab" and I cant find:

So I download from external webs but am not sure if it doesn’t work or is my phone´s problem.
I explain exactly all my probes that i did before this post, an actually I am really feel that I´m loose this battle, so please if anybody has an idea it´ll be great!
I beging with no IMEI, so the phone can´t take network to use it. Always that become dead the only way to recuperate it is flash via odin:

After that I can swicth on, but steel without IMEI and network; and of course KNOX activated.
Ok, let´s go to explain what I did before in case this can give aut some information:
1.- To recuperate the IMEI with ARIZA-Path
http://forum.xda-developers.com/galaxy-s3/help/solved-siii-network-problem-update-sn-t1918601
I obtain root access to install busy-box and ariza-patch with KNOX activated. The patch was apply correctly, but it wasn’t recuperate the IMEI
2.- To recuperate the modem or base band using different files
Here I used many post from XDA testing different modems, patch and baseband according of my PDA file in every moment. But still no work, sometimes become in CWM mode "signature fail", other via odin "PASS"; but the conclusion in every case is the same, "phone unknown, no baseband, no IMEI..."
Here I have other question, when u flash the modem, for example "XXDME4 / DXDMF1 / DDMG1" do you have to put only the correct one (DXDMF1 in my case) or all of it. I did both, just to try.
http://forum.xda-developers.com/showthread.php?t=1584250 to read and http://forum.xda-developers.com/showthread.php?t=2044937 to download modems
http://forum.xda-developers.com/showthread.php?t=2468119
3.- To recuperate the IMEI via flash Philz after that in CWM using this post http://forum.xda-developers.com/showthread.php?t=2536418
The same situation
4.- To complete flash and recovery with http://forum.xda-developers.com/showthread.php?t=2154890
I did the same operation in other S-4 and works, but here my problem is:
- The complete pack of 5 files to flash it via odin, I only found for android 4.1.2
- If I try to downgrade with KNOX active, become "FAIL"
- If I try to flash a version of android 4.3 without KNOX, appears one more time the same "FAIL"
Posible solution for that ¿¡?
- Find out a complete flash files for android 4.3 (PDA, MODEM or baseband, BOOTLOADER, CSS and in case Pit file)
- Downgrade to 4.1.2 and install OXA pack that I have it
- Restore it for SAT http://forum.xda-developers.com/showthread.php?t=2618261 with flash counter in 0
- Use KIES to restore it (I hate this possible solution) external link obviously in http://www.droidviews.com/firmware-upgrade-encountered-an-issue-solution/
Hopefully u posts it in correct place and someone can help me.
Regards to moderates people and every person who post looking for helps to others.
To Downgrade you N7100 and remove KNOX you need
1. OLD JTAG microSD card
2. Open the phone
3. Short Resistor
4. Power up the phone
5. Wait for success message
6. Assembly back
7. Flash to ANY old SW and Knox will not showed in Download Mode
Many phones checked like that

[Q] [Help] Firmware change

What's up people as they are?
I need unlock my Samsung Galaxy S4 Mini is Movistar (I'm from Argentina), I wanted to release and I could release the RegionLock Away but for a few weeks, then re-locked and this time says "Not registered on network" when I want to make calls, says "No Service" or "emergency calls only" on top where I should say Movistar.
I think it is problem of EFS folder; associated with the IMEI; you ... that I read and do not know how to fix it:
Another thing i was thinking is to change the FIRMWARE / ROM, but I'm in doubt which put as down 2 and were TIGO Personal and nothing to do .. :S; also i was reading and it seems that I have to download this (I download from SamMobile versions STOCK)

You might have trouble getting an Odin flash to succeed due to the 4.4.2 rom and it's bootloader. Try to flash the device's 4.1.1 modem to allow the menu options needed to unlock the device. Once the unlock is completed you can flash the correct modem back to the device.
what you can do is flash the 4.1.1 modem which should give you the options you need to unlock.

Need modem for 7.1.1
