Dear all,
I have searched the web and flashed my phone for over 20 times in order to fix it after my serious mistake, I got no clue and decided to ask for help here. My phone is N7105 bought in Hong Kong. I would try to describe my issue using the fewest words...
- How things happen
1, I downloaded the latest 4.3 TGY firmware from sammobile, flashed it using mobile odin pro as I want to keep the root. After that I cannot connect wifi. Searching the web revealed that this is due to the old bootloader issue as BL did not update if flash by mobile odin.
2, Biggest mistake here. I know I should try to flash the firmware again by PC odin. However as I was not able to have a PC access yesterday I decided to see if some quick fix can help. I found a wifi fix in XDA (wifi_fix_for_MJ2.rar). I know it is for N7100 not N7105, but as It stated it is a fix I though nothing harm (very wrong!!!) and flashed it. After that my phone got the wifi back but have IMEI damaged. The phone is not able to reconize my sim after that.
3, I flashed the 4.3 TGY firmware by PC odin after I got back to home. (So the bootloader is 4.3 now). IMEI still cannot be fixed and SIM cannot be read.
- What resolution I have tried
Now I fully understand what's going wrong and I tried the following fix, but they all not working.
A, Using PC odin to flash the latest 4.1.2 firmware. This not working as odin refuse to flash, should be the 4.3 bootloader prevented this.
B, Using PC odin to get root and CWM <- OK. And then got a 4.1.2 firmware in CWM update zip format, put it in ext sd card and flash it in CWM <- OK. My phone seems to downgrad to 4.1.2. IMEI still damaged, no SIM. And phone is unstable (may hang after a while if it put idle, need reboot). Although it is 4.1.2 now I think the BL is still 4.3, as I still can't flash any 4.1.2 firmware by PC odin. And everytime I flash 4.1.2 firmware by PC odin it will appear fail on screen, and also render my phone dead. My phone would then cannot boot up and require to flash a 4.3 firmware again...
C, Tried to use Kie firmware restore feature. It flashed the 4.3 firmware but can't fix the IMEI issue.
D, Tried the EFS Professional but I don't know how to use it as I don't have a EFS backup before.
E, I got a param.bin from a thread of XDA (not sure if it is a good one or not, but the writer said it is for N7105). I flashed it using PC odin, status unchanged. (http://forum.xda-developers.com/showpost.php?p=47861647&postcount=242&nocache=1&z=8137774079208057)
- What help I am seeking for
1, Any EFS backup from you for N7105 which I can try? Maybe I can edit my own IMEI no. inside it?
2, Any way to restore the EFS data from flash?
3, Anyway to get back to a true 4.1.2 BL such that I can free to use PC odin to try different 4.1.2 rom? Currently I can only try to obtain CWM zip rom and it did not help.
4, Any other way which you can suggest?
Thank you so much for reading my help request...:crying:

Yes, it helped!
I searched this thread before but it was intended for I9305 but not N7105, so I did not apply the fix before. But the file Param_Bin_I9305.tar turn out worked for N7105!
Still if there is a way to downgrade my BL to 4.1.2 I am very much appreciated.
It helped for my issue also.
Quick description what was my situation as it may help others:
Got a N7105 with a 4.1.2 ROM. For some reason installed rom for a AT&T version 4.4.2. Got a NULL/NULL imei and no wifi, mobile or anything on phone.
Trying to resolve the issue installed stock rom 4.3 (from sammobile) and stuck on loading screen. Few attempts later and waiting at least 20 min after each odin installation I've lost all hope. Installed ParamBin file from the mentioned thread and what a surprise - phone booted and all is working fine.
Thanks for this post, saved me.
I updated to Cyanogenmod 11's latest nightly of 4/26/2015 and my phone started behaving badly.
I kept losing signal and having trouble making calls and in my attempts to resolve the issue by flashing back to a previous nightly it seems I lost my IMEI and with it connectivity.
I found a video on youtube that says to access the service menu to fix it but CyanogenMod doesn't do anything when I enter the codes in the dialer so I was attempting tro go back to stock but having trouble finding a good stock rom I can use and the 2 I"ve tried both fail in odin. Then I read something about needed a pit file but flashing that fails to.
So right now I went back stop recovery but still on Cyanogenmod but the phone doesn't do anything when it boots...just no connection.
Someone told me the pros in this forum could help so here I am, help me Cell Phone Gods!!!:crying:
Got this phone info app that says bootloader is I747UCUEMJB
Update 5/5/2015 I'm on latest bootloader and running stock rom but have no data and both calling and text work randomly. 4G symbol comes on once in a while but most of the service I do get when it works is on edge network.
Sounds like your modem may be messed up.
Load a terminal app and use the app to verify the bootloader on your phone.

Try this: boot into download and read the screen. Do you see anything about warranty bit on the phone?

Yes, says Warranty bit 1
system status official.
What's that tell you?
btw i just went back to CWM
got this phone info app that says bootloader is I747UCUEMJB
Odin is failing with the stock ROM from sammobile because the phone has at least a 4.3 bootloader on your phone. Do not flash anything from sammobile because attempting to do so could brick your phone.
Since you're back on cwm with an mjb bootloader, try flashing the mjb modem via cwm.

I tried flashing the modem before...I'll do it again...is that going to get me my IMEI number back or allow me to flash stock rom to recover my IMEI?

I did flash the modem you linked and that improved things a bit...I'm back to the original problem, I was having where my phone was having trouble staying on the network. I had even lost all my APNs in my attempts to fix. Now my APNs are back. Still showing unkown IMEI and phone isn't getting on the cell phone network.
So the baseband is now mjb?
Try flashing the latest release of CM10.2. It's possible you need to update the modem and bootloader together in order to support the newest release of CM11. I don't have an s3 so i can't confirm my theory.
You may have to try nvwriter to inject the imei as a last resort: http://forum.xda-developers.com/showthread.php?t=1804117

Yes baseband is MJB.
I'll install 10.2 real quick. In the past that didn't help but who knows this time.
OK. Installed 10.2.1 and still have null imei. Connects to cell networks unreliably but no data and texting.

Did you confirm that your modem and bootloader match? Did you try nvwriter to inject the imei?
I believe modem and bootloader match. Haven't tried nvwriter...can't access service mode on cyanogen apparently.
What do I do now?

The NV Writer method, I get stuck at this point in the instructions
"*If you are running a aosp rom (cm9,cm10,aokp etc) you can use the diag method described HERE"
The link is dead so I've no idea what I'm supposed to do.
Since your imei is null, I'm not sure what else to suggest except to re-flash the existing bootloader and modem or flash a newer bootloader and modem.

There is a newer bootloader and modem?
I sure wish I had an easier time with finding out this info plus the files.

I use both tar and yes i use odin AP
im having the same problem with my 925t =/ just unknown baseband though
Did you chdck the md5 after download? And also where did you download the stock tar? You may have been on oj6 and i cannot find the tar for that? I suggest downloading from sammy and use odin to flash.
Hi everyone,
I know this problem is well known and solved many times already, but I'm not being able to solve it by myself. This is why I'm posting this thread as a last resort to try and get some help, just in case i missed something..
My phone is currently with unknown baseband and IMEI on stock 4.4.2 flashed via kies recovery. If I try to flash any 4.4.4 port ROM the phone locks up seconds after boot, it will only work with stock rom. I already tried a few modems i found on another threads but no success.
Can anyone help?
Thanks.

from sammobile, download newest firmware for your region and unpack it from stock rom and then pack it with 7zip to tar file and flash it with Odin.
you need sboot and modem

Isn't that a bit pointless? Maybe I'm missing the point, but if I already have flashed latest firmwares from both sammobile and kies, it kind of makes the point that modem and bootloader files from sammobile don't solve the problem, right?
Thanks.

Well truly doesnt seem pointless
I got my baseband resolved (Previously showed 'Unknown') by flashing pure stock rom (got from SamMobile) THROUGH ODIN so might be there is a point.
Try stock rom flashing from odin as according to me stock rom has everything in it radio(Baseband),boot(efs), system, etc etc
The unknown baseband and imei can be due to a modem and bootloader mismatch.
To confirm the bootloader and modem on the phone, install the Samsung Phone Info app from the play store to confirm the version.
