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?

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.

I have a T-Mobile Samsung Galaxy S3 (SGH-T999) and I made the mistake of allowing an upgrade??? to android 4.3 which has been very unstable for me. T-Mobile, Samsung, and Google all say that there are no updates to 4.3 and I can’t downgrade, so basically I’m out of luck.
Can I downgrade 4.3 to 4.1.2 without bricking my phone and hopefully without voiding my warranty? If so, please give me some instructions. I downloaded Odin 3.07 and firmware: root66_TMO_T999UVDMD5.7z. Thanks a million.
I don't think it's possible to downgrade anymore due to Knox. There was a thread talking about it

if you flash the root66 of the md5 firmware via odin after you have already upgraded to 4.3 you will HARD BRICK your phone. Taking the 4.3 ota updates your bootloader and flashing anything other than 4.3 in odin will wreck your life.
You need to download the root66mjc firmware here:
http://www.androidfilehost.com/?fid=23212708291682181
And flash it in odin. Then from there install a custom recovery and download a rom of your choosing and the compatible modem. I recommend you download the md5 modem. Then you're gonna wanna boot into recovery and flash the rom and the modem only (kernels are ok of course) JUST NO BOOTLOADERS. I don't even know if you can do that in recovery but trying to mess with the new BL will brick your face I mean phone.
full steps?
so does anyone have any full list of steps and links on where to get the modems and all to downgrade 4.3 with knox down to 4.1.2

I was referring to the 3 persons who responded to the OP's question similar to yours. @jtl_777's response is pointing to the 4.3 Firmware.
Its more implied in this thread than stated matter of factly. This thread is several months old, and I know your question has been asked countless times in many different threads, much more recently than in this one.
I suggest you read the stickies in each section. Just by doing that you will find all firmware and modems and more. You will also find that the answer is no, you cannot downgrade your full firmware from 4.3. And you never will be able to.
If your having problems I suggest flashing the latest 4.3 build via Odin, then factory resetting. Start over clean with minimal restoring of backups (only the essentials).
Every time an update comes out there are people who have problems. The majority are solved by doing what I just said because most bugs are caused by using old data created by old apps on the new build.
Even if you could downgrade, chances are youd run into even more issues and still have to factory reset.

thanks but I read online and some youtube videos showing that people have gone from 4.3 back to 4.1.2, just trying to make the phone the way it was before any updates were done and wondering if anyone knows the proper steps without bricking the phone.
They probably just flashed a rom. It is simply not possible to downgrade the firmware though.

so do i just download the below file, extract and flash via odin then do a wipe via recovery? If not can you please explain how to go about this so i can have 4.1.2 running on the phone

great thanks so much for your help, can I flash the recovery via odin mobile app or is it safer to do it via pc?
Safer via PC.
It is possible via Mobile Odin. But that's one of the partitions I don't want to mess with when Phone is Booted/
If you know how to use Mobile Odin then it should be fine. I agree that its better to use pc odin if youre not familiar with Mobile Odin. However, it actually doesnt flash the recovery while booted. It flashes the flash kernel which is MO's temp recovery. It then boots to this and flashes. (So, perseus is right in that regard. But I personally love Mobile Odin and find it extremely useful and consider it safe unless you are brand new to all of this).
In fact Mobile Odin is another way you can flash 4.1.2. Itll flash the firmware, but only the system, kernel, recovery and modem. (I didnt bring this up previously because I didnt want to confuse, or go too far too fast).
If youre thinking about flashing recovery via MO, though, you can also instead just flash the rom you found. No need to flash the recovery unless you just want to. Put the rom in the update.zip slot and itll flash just fine.
If any of this is confusing, just stick with the original plan for now. The rest will come easy if you dont rush things.
One more thing, while you can usually update stock without wiping, you may find you have to factory reset after downgrading as the old system was not built for using data created on a new version.

thanks for all the help.. had to do the wipe since it kept showing the samsung logo but after that it booted just fine.

some of us need the updated bootloader because the current wave of custom kernels doesnt play nicely with wifi calling and you cant run a KitKat kernel without the KitKat bootloader

The only "benefit" is running the new TouchWiz kitkat builds with WiFi calling on the TMO network. The new bootloader is otherwise considered a downgrade.

If I remember right, once on 4.3 you can no longer use the free unlock method. You will have to buy a code online. If you have a T999, you can try flashing the 4.1.1 modem and see if you can do it though. You wont get any signal if you are on a 4.3 rom until you flash back to the 4.3 modem btw.

You dont need to be rooted, but you do need a custom recovery (TWRP or CWM) in order to flash the modem. I never made any odin flashable packages for the modems, only recovery flashable.
Just so you know, flashing a custom recovery will void your warranty if its still valid and you care about that.
Thanks bro, I don't care about warranty.... So all I have to do now is flash a recovery then flash the modem, hmm wonder if anyone has ever got it to work like that before tho.... If it doesn't tho can u recommend a cheap unlocking site please

All I remember for sure is that on 4.1.2, samsung patched against this unlock method, but we were still able to flash the 4.1.1 modem and unlock. In 4.3, you cant use an older modem or youll get no signal, but Im just not sure if you can still use the free unlock method that way.
Ebay had several very cheap options at one point. Also, http://gsmliberty.net has/had(?) a promo where if you posted a video of yourself unlocking using their method they would refund you your money, essentially making it free. Not sure if that is still valid though.

There were several mentions of specific sellers that only charged a few bucks in the unlock thread if you want to dig in to find them.

Any 4.1.1 modem, as long as its one for your model device. If you wanted you could see if flashing a 4.1.1 or 4.1.2 rom would make a difference, but as before, I kinda doubt it will.
When we were updated to 4.1.2, and found that the unlock method was patched, all we had to do was flash an older modem. Didnt matter what build it was from.
agree

i guess this way is ok.
use rom 4,1,1 and the modem for rom 4.1.1, phone should work fine, hope someone can try this way. and tell us the result.
Hey all. So im usually not in these threads, i own a sprint note3 myself. But my friend has a metropcs s4( SGH-M919N, jfltetmo). And he wants to root but dosent know much about rooting, roms ,and such. I would say im pretty good with these things, ive had a lot of experaince, just not with the s4. So basically i did some research and im putting a mini guide below of my understanding of how to pimp out this phone! If anyone could correct, add-to; and answer some of the questions I had. Thanks Folks!
General Questions
First off. My understanding is T-mobile and metropcs software is NEARLY identical.
1.What is the current version/ name of the latest T-mobile s4 software.
2.What is the current version/ name of the latest metro pcs s4 software.
3.Are they identical, or compatible. Meaning could i odin the latest stock tmobile s4.tar software on metropcs phone, and have everything work properly. (In case i were softbricked)
4. If not could someone please link me to where i could find the official stock metro-pcs..Tars (flashable with odin)
Rooting methods:
1.)This is Chainfires Auto-Root for t-mobile S4 which some have said worked well for them. Thou I have read of issues (loss of wifi- Fails)
http://forum.xda-developers.com/showthread.php?t=2294005
is this the best most current rooting method for metropcs phone? Again any success or issues?
OR..
2.) Injecting twrp then flashing Update-Supersu
This is the most used rooting method for note3 and it seems fairly universal. Would this likely work for Metropcs S4?
Step 1: Place "UPDATE-SuperSU-v1.94.zip" on sd card. This is Chainfires flashable root (http://download.chainfire.eu/396/SuperSU/)
Step 2: Odin twrp-2.7.1.0.tar for tmobile s4 (http://teamw.in/project/twrp2/179)
Step 3: immediately boot into twrp. Flash UPDATE-SuperSU-v1.94.zip.
Reboot: Done
Theoretically this should easily root phone and instal twrp recovery, without changing stock software...thus, no issues. YES?
Unrooting
Again could someone please point me to the correct stock software .tar that I could odin to unroot, un-soft brick the metropcs s4
Custom roms:
I hear that the custom roms for Tmboile and Metropcs are very interchagnale
Obviously the AOSP unified custom roms should be safe to flash without issues. (jflte roms)
(Cm s4 unified nightlies: http://download.cyanogenmod.org/?device=jflte&type=nightly)
BUT:
what about touchwiz based roms. Are there any specifc toucwiz metropcs custom roms to flash. Or can any of the t-mobile toucwiz custom roms be flashed to metropcs phone.
so again. If anyone could give me their thoughts/ideas, and clear up some of the questions i had and point me to best/safest way of working with the metropcs s4. Thanks in advance, sorry i know its a lot of reading: :good:
:cyclops:
4.3 or 4.4.2? I have a Metro Gs4 and I used saferoot on 4.3 with no complications at all. And any TW ROM will work.

thanks for the reply.. but ya i was asking what is the latest official software for the metropcs s4, and what is it called. I havent been able to take a look at the phone yet, so im having to look everything up.
My understanding is that the metro pcs was only upgraded to 4.3 with the name of mk5.
was there a kit-kat update released for metro s4?
1) NB4
2) don't know but I think it does have 4.4.2 update
3) pretty identical but I would not interchange firmwares
4) sammobile.com
Root
1) no issues with me with M919 using that method
2) I wouldn't recommend doing it this way, after 4.3 it doesn't work very well.. It looks like you're looking to flash a ROM, so root isn't even needed, just flash a recovery with Odin and flash ROM.. Although this will trip Knox counter.
Unrooting just flash stock firmware
Custom ROMs: aosp or touchwiz will work without issues.. If WiFi does not work, flash NB4 baseband (safe to flash on M919N)

From what I am told the s4 for Metro is still coming our with 4.3 JB. But once the phone is activated you have to opt out of the update when it asks. I have been treating MK5 just as if it was MK2 and I have not had any issues.

Thank you so much for the Stock firmware! :good:
I'm a bit overwhelmed by all the *seemingly* conflicting responses.
So i got a chance to look at the phone. It is 4.3 Mk5, What is MK2?
So, so far your "saferoot" root method seems to be the safest most compatible root method from what ive read.
thou as far as installing custom recoveries Twrp seems to be the best, but ive read that 4.3 Is now a locked bootloader!???
http://forum.xda-developers.com/showthread.php?t=2544503
that sounds ridiculous. I dont believe its locked. and i should be able to odin the latest version of twrp to the device, right? I know knox has been implemented in 4.3+ but thats no big deal
also about roms:
I know that the actual tmobile S4 did get a kit-kat update (called NB4) the metropcs variant definitely did not
you said that any touchwiz rom would work, as did @serio22 above.
But it seems that they only stock custom roms in these threads are tmobile touchwiz kit-kat roms.
but according to @serio22 above: I should not "interchange firmwares"
So if that is true what touchwiz roms can you flash? they are all tmobile roms
My understanding was I could root, odin twrp. And flash roms. Aosp roms are golden but, i would think that since metropcs even uses tmobile network now, you should be able to flash any tmobile custom rom (even if its kitkat) and have everything functioning... True??
thank you both very much @serio22 and @Kriptik210
and im sorry to be a pain im just genuinely confused, and i really need clarification, i said id have this guys phone figured out by Monday!
Firmware is not the same as ROM, that's why I suggest you flash ROM instead of firmware, any ROM will be ok. Bootloader is not locked I'm sure, Knox bootloader does not mean locked bootloader as many people think. Just Odin twrp and flash your ROM as I said earlier, rooting would be an extra step.

ah that makes sense. Well id still want to root, just to titanium backup his things first, and have a secure stock rooted nandroid backup. Though then just a couple more questions remain :highfive:
So say i were to flash any toucwiz t-mobile kitkat rom Such as.

The OS would be kit-kat. Would i need to then odin flash a kitkat baseband (modem) as well for working signal. If so how?
Also does the kitkat rom change the bootloader already on phone.
reason being. For the note3 once you update it from JB to kitkat. The bootlaoder is changed. Meaning you CANNOT downgrade even odin flashing the previous version .tar will BRICK
is this the same case? If i flash a tmobile rom (thus upgrading), would i not be able to odin the metropcs 4.3 MK5 stock.tar
OR
would i not be able to simply restore the nandroid stock rooted MK5 backup i made.
Thanks again :highfive:

Bootloader will not update and its not needed because kernels are modified to bypass this "restriction" only thing you need to update is the modem to NB4.. There is a thread already with instructions, just follow it and you'll be good.. And yes you can still flash back to 4.3 stock and restore nandroid because bootloader will not change

Thanks a millions times over good sir! I should now be able to put together the pimpest of phones haha
Its a good feeling when things all come together. Like completing a puzzle!
:laugh:
I've heard that my MK5 bootloader is locked and others say it isn't. Serio explained everything else lol. TWRP is great. XDA doesn't permit saying things are better than another but I use TWRP and I haven't had any issues with 2.6.
