[Q] Generic IMEI after OTA 4.3 upgrade

Hello to everyone, I was wondering if anyone can help with this. I have a Galaxy Note 2 branded by an Italian company (3hg Italia). It recently received its update to Android 4.3 (update N7100XXUEML2). It was the official update OTA, the phone is not rooted and it had the stock ROM on it. The update somehow messed up my IMEI making it appear as the generic 0049 forcing me on "Emergency calls only" mode. I already tried flashing the same ROM with Odin and repeating the update with KIES, but while the updates always results successful the IMEI remains 0049. I never made a backup of the EFS folder for this phone since I haven't rooted it or flashed any different ROM on it yet. There is any chance that the phone made an automatic backup? I live in the States right now and Samsung tells me I need to ship it back to Italy to have it fixed, but that costs a lot and would take forever, and I would much prefer try to solve the problem locally. Any suggestions would be greatly appreciated, if not for any fix that I can try myself, at least some place on the West Coast that can fix the problem!
Thank you!
Lorenzo

Oh I forgot to add that because of Hardware problems I recently sent my phone to Samsung and they replaced the motherboard, which fixed the problem I was having. I don't know if that could be related!

I'm afraid that fix works just if you have your actual IMEI, I instead have the generic IMEI that starts with 0049. But I will check it out! Thanks!

Then you should simply flash another modem from here : http://forum.xda-developers.com/showthread.php?t=2044937 ... flash a custom recovery first.

So I found someone nice enough to give me a hand with this situation, but still no luck yet! Here what they say:
At first glance, the EFS data on the phone was corrupt. I re-generated
that data and restored it to the phone without success.
The GSM radio itself is operational, and the firmware for it is
installed and functional. diagnostic data flows to the towers and back
to the phone but it's not reading the IMEI from the copy of
nv_data.bin contained within EFS. I've re-generated and installed
those files as well, again with no luck.
I rolled the device back to it's original factory firmware and radio
baseband, then ran through the update for the radio baseband, which
also regenerates the contents of EFS, and still no luck.
Given the situation, anyone have other suggestions?

Try flashing 4.3 rom from scratch (wiping dalvik cache, data/factory reset and cache partition) ? May be this will help fixing problem
If you want you can try Stock Rom - http://forum.xda-developers.com/showthread.php?t=2589891

Also make sure you have an APN set. @Bajanman has compiled a list of several AT&T APNs in his thread here: http://forum.xda-developers.com/showthread.php?t=2172110

I had a similar issue and this post helped me.

Also check your SELinux setting.
Once I set mine to permissive all was well.

They are not hacking my friend...
Have you verified that your IMEI and EFS folder are normal ?
And have you verified your APN settings for your carrier ??
You mention flashing several roms on the device...
The items I listed will help you determine if any damage has been done....and also help you get service again...
All are knowledge you must have to prevent bad things from happening...
If your carrier did an official update to 4.3 while the device was rooted and running custom firmware....then you absolutely need to start fresh to clean the device up again...
Are you getting Knox errors or force close issues ??
Basically....in order to help you we need a detailed status of the device...
Software version....kernel version ....and baseband.....
The information is in settings/about phone/....and will tell us how best to proceed....g

Reading your first post, ATT flashed your phone to the latest update??? And changed the SIM? And that didn't work?
Why did you leave the store when your phone didn't work?

They told me they can't do nothing about it and the warranty was voided too.

Interesting. I'm asking questions I guess really dont matter.
But why was warranty voided, or was it expired?
Again more confusion.... Just wondering why they changed sim, flashed update, then told you to hit the street with a broke **** phone.
I can understand not replacing it, warranty whatever.
I took an Atrix2 phone into the shop, no working data. I had called tech support, they had OTA refreshed it, didnt work. Set me up with tier 2 tech support, more resets. Nothing.
Went into store, got another sim. Turns out it was simple. I had turned off the data plan awhile back until I was ready to give it to my daughter.
Got online, picked a plan. Data lite off.
Point is they worked with me to find the problem on a phone that was 2-3 years old.
You probably should follow me how to in this section and flash the stock 4.1.1 and go from there.

Well you have nothing to lose at this point then.
I doubt you will find a canned click next solution.
You will probably have to go the "hacking" route.
Good Luck.

[Q] SGH-I737M - modem issues

Hi all,
I have a Bell Canada Samsung Galaxy S3 that I can't get the modem to work on. I have Philz recovery on it and have tried a few modem files but neither the wireless or the mobile carrier works.
I have tried putting cyanogenmod on it but am back on a stock ROM at this point. I am at a bit of a loss as to what to do.
The phone boots fine, looks all normal but I just can't get on the mobile network(tried multiple SIM's).
I am really hoping you can help!

Does your phone display the correct imei when you dial *#06#??

It does, it shows my IMEI with a /5 at the end.
At this point, I am running I747MVLUEMK5_I747MOYCEMK5_BMC
I also do show cellular signal but can't seem to connect. When I scan wireless networks, I pick nothing up.
Any ideas?
Thanks again!

Is the phone blacklisted?

I don't think so, how can I verify that? I did buy it used just over a year ago and it only broke about a month ago?

You've had the phone for a while so I didn't think it would be blacklisted.
Since you have the 4.3 bootloader, you need to have a compatible modem and, from my experience, only the mk5 modem will work.
Did you use Odin to flash back to stock?

Yes, that is how I put the current stock firmware on it. I had cyanogenmod on it at one point...

I am at a loss as to why you cannot connect to a network. Which carrier do you want to connect with?

Need help - No call audio on rooted phone w/ m919uvufnb4

Hey guys, I recently received a new s4 via warranty. Phone came with 4.4 m919uvufnb4 and NB4 boot loader.
I followed the CF root technique to get root, but for the life of me not a single rom I have tried gets working call audio. It seems all solutions posted on the forum are for people with the same issue but on an MDL boot loader.
I have tried playing with the different modems/diff. LTE modems from 4.3 and 4.2 but no luck.
Tried 4.4 GE rom, and Cynogen/AOSP roms - no luck
Any help is appreciated guys - Really want to get his working if at all possible and haven't been able to find anything. Thank you :good:

No my friend didn't try that. But shouldn't the phone already come with nb4 firmware being that it came with nb4 out the box vs an upgraded phone?

Yes it should, but those symptoms sound like maybe something didn't flash right, if that doesn't work I would contact T-Mobile for a replacement.. Looks for Fenny's 4.4.2 firmware

Now that i think about it, i have flashed original 4.4 back on it but never tested call audio.
But just to further describe my issue. On custom roms audio does initially work but eventually stops working after a call or two.
I wi definitely flash nb4 firmware back on and test. Ill paot results shortly.
Thx!

Honestly im not the best reource to answer your question, being this happened to me so long ago. I do remember the struggle of dif. Roms, and flashing the correct baseband didnt work. Last avail was flashing back to stock via odin and still no sound.
At that point i contacted my phone carrier who was responsible for sending me the defective phone. Since then my new exchange was all good.
Hope that was some assistance, i know this is a real headache. Goodluck!

plus help
Has anyone figured this out? *#0*# TEST . Receiver making sounds like Speakers . BMW microphone does not work on voice commands or text nor voice recorder. But if I record a video clip .you can hear my voice. Is there a fix for this? Can't return phone.

[Q] Insert SIM card to access network services

Hey all. I made a big mistake. I accidentally flashed Android Revolution HD on my T889, not realizing that it wouldn't work. The ROM worked great, but I had no service or data.
I figured just flashing a ROM that was actually meant for the T889 would fix my issue, so I jumped on over to Jedi and the same issue persists. I'm at a loss and I'm not sure what exactly I can do to fix this. The information out there on this issue seems to be pretty spread out and inconclusive. I'm perfectly ok with reverting to a stock ROM if that is what I need to do. Any help pointing me in the right direction would be so greatly appreciated. Some answers I've come across are "flash the latest modem for your phone" but I can't for the life of me find working downloads for that.
I've also seen a few posts about IMEI related stuff. Unfortunately, I jumped right into this without the knowledge that I needed to back up my EFS folder. Do I have a brick on my hands?

I don't believe it's a baseband issue if it shows up under Settings-->About phone, you can also check your IMEI from the Status option there. Here's a modem I believe is the latest for your phone UVUCMK7 I don't have this phone so best of luck!

Thank you for the link. I'm going to try it and see if it works. Under Settings-->About phone my baseband shows up as unknown and under status so does my IMEI.
