Just bought note 2 - Have I broke it already!? Help please.

Hello,
So bought my note 2 from amazon, international version, sim free.
So i rooted it and fired a custom firmware on it.
Decided i prefer having the functionality of the s pen and wanted to reinstall the original f/w.
So managed to get an original samsung firmware (BTU) csc.
All is well on it apart from my sim card does not work in it (no service).
works fine in my old phone still.
It doesn't allow me to update it over the air and kies is a nightmare.
So im stuck with a tablet at the moment that I cant update.
I think I may not have the correct original firmware but I dont know how to determine which one will work!
Any input would be appreciated....
Thanks
Dan

You seem to have stumbled upon the problem introduced by Samsung in their newest kernels (they are used in newer ROMs).
The kernels cause IMEI number to not be recognised after flashing old firmware once the new one was installed. The only recourse is to root again and flash back one of the newer roms (Phoenix, Omega or Android Revolution will do nicely) or try to find original Samsung firmware for your region, but it has to be one of DM6, DF1 or DG1 at the end of the name and flash it using Odin.
Look here and remember to match your phone model number as well as firmware region.

I hope you've managed to keep a backup of the EFS partition. It's really important that you do.

Efs partition is where your phones unique identifiers like imei are stored. If it gets damaged or wiped and you have no backup then your phone is a brick, pure and simple.

Try and Flash an official dme6 or dmf firmware as per above poster. If imei is still blank then your phone is a brick.
I don't know why there are so many how to root blogs on the Internet and none of them tell you how to back up efs or why it's critical. It's a complete tragedy.
I've had to restore imei once to save my gs3. Was very lucky I'd flashed an omega rom earlier and the aroma installer asked me if I'd like to do a backup and told me it's important. I heeded the developers advice and backed up said files to drop box. Now I always do it immediately after rooting - all custom recoveries give an option to back up efs.
I hope it's not too late, it's sad for people to have to learn the hard way, best of luck.

Ive just read that if you flash the latest modem you should be alright. The post to guide you on this is by Dr Ketan in the original android development section.
I dont think your phone is bricked I think if you flash the very latest modem you should be alright. Just remember when flashing anything to your phone you should always make a nandroid back up first and copy it to your pc just in case for safe keeping plus a copy of efs folder. I hope for your sake you can sort this. And remember to read thoroughly all instructions before anything else. Look here and click the read this first it should help you..

Well I flashed the oldest note 2 rom I could find 4.1.1 and I have an imei number back!
Still won't connect to my phone network.
I does show networks now at least!
Emergency calls only.
So if I install the new modem on this old firmware would that work?

Could I just flash any of them? Even the Indian one?

I'd suggest you backup your efs before trying anything else.
Does your baseband version display now?
If you've already had your baseband updated to the new versions then you can't use it with Perseus kernel. The new modems are interdependent to the new kernels and Perseus hasn't been updated in awhile.
If baseband is newer one then you need an up to date kernel and flashing a newer firmware will obviously address this.

You have nothing to lose at the moment your phone is a semi brick. I think by reading Dr Ketans guide you will be able to get that phone working again. I take no responsibility from the following link but I think you need to give it a go. If you havent backwd up your efs folder than this link may help you. Id say download this latest modem and recovery and again I take no responsibility for your device.

[Q] Samsung Galaxy S II X T989D - Lost IMEI

Hey everybody, my supervisor was installing a custom ROM (IIRC cyanogenmod) when something happend and he lost his IMEI and IMEI SV number making the phone unsuable.
I believe he didn't backup the EFS folder and lost the contents which included the IMEI.
Is there any way I can fix this phone and get it back up and running?
I've found another thread which refered to re-programming the IMEI with some expensive device.

U could JTAG it, or try hemidell, u might be able to rewrite a new imei number, if not idk, how did he lose that? Flashing a ROM shouldn't have erased his imei ?

Thanks guys for the response.
What he flashed to/what he did etc...I have no idea. I have the phone with me and I'm trying to start fresh and get it to work. I have no idea what he did so I'm just trying to start at the begining and learn myself to see if I can correct the problem.
All I know is that when I check the IMEI on the phone info, it says 0 and IMEI SV says 0 also

so there is successfully a ROM installed right now correct ? go into about phone and check what it is running and what kernel what baseband the whole nine bro gimme something else to work with other than being blind trying to help bro lol . are you familiar with any rooting or odin flashing at all ?

It currently has a ROM installed, the phone functions but has no IMEI at all listed in the ABOUT PHONE section. I will get that info later today after work, thank you very much!
I myself have a Galaxy Nexus which I flashed from ICS to Jelly bean and used the ICS radio file rather then the JB one. I can follow instructions but I am new to android. I'm a Blackberry guy from the past and work with blackberries in a corporate enviroment

lol i know it has a ROM installed but when you go into about phone it tells you what your running ?? and no problem man

Honestly, the only way I could think of where he lost the IMEI of the device is if a nandroid backup was created lacking the EFS partition and was restored or the ROM didn't create an EFS while flashing. I've heard of some ROMs, mere flashing of updates or a clean install, mess with the radio/baseband and leave the phone without one, rendering it unusable when it comes to connecting to a cellular network until you flash a radio but not something like this where the IMEI is borked and lost.

Had the same problem as you did, I always made backups and indeed a tar.gz backup, Unpack the backup and copy it to the efs folder(Root), also make a backup of the current efs folder so you can't sink further. You'll need root explorer for this with read/write.

I tried..still the same..
I used root explorer and copy to the efs folder and then restart..

Latest version of omega rom? Did you update modem or Flash a kernel?
Please post screenshots of your "about device" page.
Most likely you simply have a kernel/modem combination which is incompatible. Should be easy enough to fix if we can get you back to a matching configuration.

Heres one solution to the imei problem on n7100. When you flash a new rom your efs containing imei wifi bluetooth etc gets corrupted/repartitioned this is apparently a fix by flashing the modem posted and a compatible kernel. I will warn you though another guy had the same problem and every guude tutorials we followed did not work and his n7100 was left a brick. In the end he used triangle away flashed a stock rom and unrooted and it had to be sent back to service centre..

You need to flash the modem in the link via odin.. im not sure if you then manually need to extract your backup of efs back to root. You also need an upto date kernel. Im not sure which but it needs to be a recent one..
Sent from my GT-N7105 using xda premium

You need to do things in this order:
1. Flash a stock firmware older than DME6
2. Root again using cf-autoroot or similar
3. Use an app such as root Explorer to copy from your efs backup into the /efs folder on your phone.
I've done this at least 3 times now as I often test new roms and the imei is always messed up until after I restore the efs backup I've had in dropbox since the very day I purchased this phone.
I broke my s3 by failing to back up efs and I'd never make that mistake again.

If you use the search feature and tap in "lost imei" all your questions will have answers. It looks like you have an n7100. And by the look of things you were on mc3 4.1.2 and flashed an older rom of 4.1.1 I dont think you can do that..

for that u will need to flash stock rom via odin. do not panic. this thing has become very common now. search in android development section of note 2.guides are available todouble bled it ok. just do not panic.read the guides carefully and double check what u r doing.

I had a problem like this except it happened when I flashed a rom. The rom corrupted my SD Card so I lost my backup and even after flashing stock it did not work. Eventually I sent it in to Samsung. Now I have learnt my lesson to keep a backup on multiple locations

It is because of downgrade of your rom.
Some time downgrade results in conflict modem and efs data corruptions.
It recommend to immediate take a backup of efs files after root.
Now do fiollowing steps
1. flash DMC3 full rom( Not only modem).
2. Wipe data and cache.
3. Wipe dalvike cache.
4. Reboot device.
It may solve your problem.

DMC3 also older rom for countries mentioned above.
Flash mg1 or simply look N7100 all in one on my signature, look post #6 and download modem for mg1 (it will have kernel, recovery and modem) you need modem only for network issue but I recommend to flash all three as your current rom I think not sds patched.

Any idea ???

I lost my imei number a lil. Time ago and I don't know what could be the cause of this
I tried two different things that day i.e.
I flashed a wifi direct file for kitkat 4.4 based rom and then I partitioned my sd card and after sometime I lost my imei no.
So any one can tell me what could be the reason

Reason u already told main.thing is recovery ... do u have a efs backup???
