Hi Guy,
Yesterday I unlocked my phone in hopes of placing it to another carrier I have at&t. That was successful. I then flashed the modem in hope to get Tmobile 4g working on my phone. But it was giving me issues. I was running Rooted Stock ICS at the time. After doing some reading amount the threads, I've concluded that I probably needed to get a ROM(?) in order for this to work? So I flashed ParaniodAndroids JB on it. Well my new problem is, that I lost the baseband and my IMEI number...and I have no way of getting it back. I did write it down. So I know what my number is, but is there any way to get it back? At this point, I'm ready to give up. I've spent hours looking for info on how to fix this issue. I actually wish I was back to my ICS now. Right now my phone is useless without any signal.
So does this mean that I have a bricked phone? Please let me know if there's anything I can do to salvage my phone.
Thank you.
Reflash the appropriate modem (re download old one could be bad) and then make sure you set the APN to a proper T-Mobile one. That should hopefully get you going.
I'm not sure where your imei went, it should be in the "about phone" section. But it you don't see it there its also on a sticker behind the battery I think. At least that's where I've found the printed imei before.

UPDATE
So I did a complete unroot using Odin. Once I did that all of my info came back to normal. However, I am back to GingerBread. Which isn't great, but I know where to go from here.
If anyone is still having trouble restoring their IMEI number, try Unrooting your phone completely. It worked for me.
Best of luck and Thanks!

Hey all, I come from SGS4G forums, I know my way of flashing and whatnot with that device. However, a friend of mine owns a SGSII and has a weird issue that I hope you guys can help me fix.
The thing is, the device no longer recognizes the SIM card, or any other sim card. She already tried it on another device and the SIM is working fine. Also, the IMEI got corrupted.
I asked her what she was doing or what did she do with the phone. She told me that she was playing the sims and the battery died. So she plugged it in, waited a few minutes and then she turned it on.
After booting up, the phone didn't recognize the SIM card anymore.
As for ROM installed, she never replaced original ROM, nor ever tried to root the phone. This is what her device status states:
Baseband version: unknown
Kernel: [email protected]#2.
Build gingerbread.uhkg7
I really don't know how to proceed in this case. If it was my SGS4G, I would try to flash another modem using odin, but I don't know how it's done with this sgs2. So I ask the experts here to help me a bit.
Thanks in advance!
ps: i have no access to the device, my friend lives in a town far, far away.
I guess she didn't have efs backup, there are guide to recover imei I think it was in general thread, if those guides don't work, her pretty much final chance is to contact xda member called odia, he can restore imei's

If the phone is running stock firmware, why would you risk voiding the warranty by messing around with it ? If you stuff it up, your friend will either end up with a $500 paperweight, or she'll end up paying to have it repaired.
In other words, tell her to send the phone in for warranty repair/replacement. It's a no brainer.

I was just asking if there was an "easy" way to fix this, like, flashing some other rom. If that didn't work we would just rollback to stock.
Anyway, looks like we're going to go with the warranty card this time.
I'm still open for suggestion though, I can't believe this device would damage itself just by running out of battery when playing a game.
And yeah, no efs backup I'm afraid.
There isn't easy fix for this
Sent from my sgs2 running cm9 using xda app
It's not a matter of an easy fix. There's never an easy fix for borked EFS details. You risk stuffing the phone up & voiding the warranty in the process, which means if your friend wants it fixed, she ends up paying whatever it costs on top of what she's forked out for the phone.
Use the warranty, she pays nothing.
Think about it.
Edit to add - Also bear in mind you're going to be telling her what to do with the phone given you don't have access to it yourself. If she misunderstands something you tell her to do, kaput.

You could try first a factory reset
Then flash stock firmware both have been known to occasionally fix IMEI .
Did for me once .

The first thing I suggested my friend was to do a factory reset. However, it didn't make any difference. In fact, I thing she came across with an error message saying something about not being able to mount efs files or something like that (she wasn't very clear, but she did mention EFS).
I would definitely try to odin (or kies) another stock ROM but since it isn't my phone and my friend isn't too tech savvy either then I think it's better to send it back for warranty.
Thank you all
On Saturday night I foolishly loaded AT&T's MIUI on my phone, then flashed with Scott's patch for Verizon.
-NO GOOD-
Since I did this, my phone was stuck in roaming. So I odin'ed back to stock, and did a ##RTN# from the hidden menu, which gave me back "no roaming" and restored voice and 3g connectivity. Unfortunately, I can't get my 4g back.
So Verizon is sending me a "certified like new replacement" which I'm not OK with. How do I pull the information I need off the CLNR, like the screwed up EFS system, and write it to the new phone using dd? Someone said there are 3 EFS partitions to be backed up, which don't contain the IMEI or anything sensitive (my imei is fine). What 3 parititons do I need to backup and what is the correct dd options like BS, etc. to accomplish this?
If I'm successful, I'll put the CLNR back in the box and send it back to them.
Not sure if you can do that since it goes off you device serial number. Also the new one will most likely have the new ota and you will not be able to unlock until adam releases the new unlock method. I thought I seen someone say that the root 66 odin fixed their 4g issues after making a similar mistake.

Start here these guys had similar issues.http://forum.xda-developers.com/showthread.php?t=2043636&page=163 they had issues with root but I swear somewhere one of these guys did the same thing.
Sorry I can not fi d tbe original post where he had the same problem. Been reading a lot and the threads are pretty cluddered lately specially after the ota.
Back on stock root 66... still no 4g... i download the phone info app and can't select anything related to LTE and make it stick. As soon as I step back out the menu, it reverts.
Actually I think there is a thread where they describe how to restore it with the secret menu. I hope I can find that thread for you or someone else can help out. I will keep looking.

Re: Can't get 4g back
The problem ended up being with the prl... go figure... I grabbed a spare SIM and activated it, which triggered a prl download. I guessed it may have had something to do with that after I was able to force LTE from the hidden menu.

Hey guys,
So I got a real doozy here...
I flashed my Verizon Note 2 (SCH-I605) to the SOKP Rom from a Jedi X Rom (v13 I believe). After the flash, I noticed my network was not working. Eventually I found out that the device was registering as a GT-7105. Not sure what went wrong, as the rom was flashed with no errors. I also ensured that my recovery was on the appropriate version (TWRP 2.6.3.3 in this case) and I also did a factory reset. To try and rectify the issue I wiped the phone and tried various other roms. In every one of those cases I found that the phone was constantly roaming. I had checked my network mode and tried switching between Global and LTE/CDMA which did nothing. Being completely out of options, I just installed to a stock rom through Odin (VRAMC3 4.1.2) and let it update via Wifi to 4.3 and still nothing. (I am well aware of the Knox security feature and will address this in a moment)
Here are the different ways I tried to diagnose the issue after this that led nowhere:
1. Made contact with a Tier-2 specialist from Verizon that tried various diagnostic methods and found that my phone was simply not registering on the Verizon network, or ANY other network for that matter.
2. I went to a Verizon store and got my SIM card replaced.
3. I even went to a repair shop to see if the phone possibly had a faulty connection.
I have already verified that the IMEI is correct based on the sticker behind the battery. The PRL is on 15310. The very last thing I tried was entering "getprop" inside a terminal. I'm taking a guess here, but I noticed my ril.serialnumber was all 0s. Could this be the problem? If there's anymore information someone needs, I'll be happy to post it up. Just hoping I can get a little direction here. If I need to root my phone again to try something, I am more than willing to. My phone is out of warranty and not insured, I'm not really concerned about the Knox warranty trigger unless it will render my phone completely unusable.

If updating the Profile and PRL on a stock based rom doesn't get it back, then you might have corrupted your EFS partition. I don't suppose you used TWRP to back up the EFS partition when you did a nandroid?
FYI: Doesn't matter what the phone is listed as (n7105) for connecting to the network. It's just a build.prop edit away from saying whatever you want it to.

Can't restore what wasn't backed up. The efs is unique to your phone. In some cases you can use another part of another phone's efs partition, but not always and is gonna be a huge hassle either way. But yea, I think you're in a pretty tricky situation. I was reading on another forum that the serial number being 0 shouldn't cause this issue though, so not really sure what to think. Usually when this sort of thing happens, the IMEI gets messed up too. Updating Profile and PRL didn't help?

I don't have a Note 2 in front of me, but generally it should be in Settings / About Phone / Update or Software Update and for most Samsung CDMA phones, the Profile and PRL options are in or around there.

Yeah, it's actually in the Status section. It does not allow me to edit anything in this area. I don't see anything that says Profile.
Hmm I guess VZW decided you don't need to have access to those functions. Weird. Sorry man, I dunno what to tell you at this stage.
Edit: Found this -
"The only acceptable way to update it on LTE phones is to take the SIM out, boot the phone back up, let it sit for 5 or 10 minutes, power off, reinsert SIM, reboot phone. That's the only one I know of, there may be other ways to do it but that is the easiest."
Not sure if it will help, but certainly isn't going to make it any worse. What baseband version do you have installed?
First thing you need to do is write down your IMEI number. You do NOT want to lose that. Seriously, write it down with a pen. Also your serial number and anything else you find in the EFS partition you might need that's specific to your phone. THEN: at this point it sounds like you'll have to find someone's EFS partition. I've seen it around on XDA multiple times as I've gone through threads similar to this one. Once you find an SCH-i605 efs you'll have to flash/replace/edit yours somehow, try editing your own first to match the same values as your peer's. Don't replace personal information tho. If you end up replacing it you'll have to go in and re-enter your own IMEI number somehow. I am not an expert on how you can do this, but stated here is/would be the process.

Hey guys, I just gave up and traded it in for an S5. I knew a guy so it was a good deal. I appreciate all the help!
Hello people, I will try to simplify and be concise on the problem/doubt I'm having:
Last week I decided to spice things up a little installing a custom ROM (was in 4.2.2, rooted) and gave a 4.3 custom ROM a try.
First flash was successful but didn't get any network. Went back to stock and all was fine (of course I had made previous nandroid and EFS backup). Second flash, during installation in AROMA installer, I ticked an option to update to latest modem. After that, I could only get emergency calls :S, even if I flashed back to stock. IMEI was right, S/N was right (I think), but no signal. It was suggested it could be a modem problem, but I still didn't grasp all the EFS v1/v2 format thing, was growing desperate and didn't want to screw things up more than already did, so, lastly, took the phone to repair service where they used BOX and my phone is all operational now on 4.3 stock build: XXUGMK6.
I want to learn from my "noobness" and am tempted to flash a custom ROM. As you would imagine, I'm still quite traumatized with the past problem and afraid I might screw things up AGAIN.
Now, I've noticed that, while my IMEI is still correct, the S/N is incorrect (not the same as written on the back), yet, my phone is fully functional.
could that cause problem, be it with EFS folder or modem, if I decide to flash a custom ROM again? Aren't IMEI and S/N suppose to coincide with what's written on the back of the phone?
I hope I explained clearly and wasn't boring! My apologies if my english isn't perfect.
Many thanks in advance!
Take it back to repair service, get them to put the right serial number back on it. Also make sure they didn't used the patched kernel and modem, to test flash the latest stock firmware or OTA update, if network is lost you'll know they didn't fix it properly.
Don't flash things you don't fully understand, read all the stickies before to do anything.

Many thanks boomboomer for your reply. Before any flashing happened, I thoroughly read and understood at least an 80% of stickies, read all details about the custom rom and familiriazed myself with all main reference and guides threads. I've flashed custom roms on previous phones I've owned. The loss of network connectivity caught off guard and was looking for a definite solution.
So, I should flash latest stock rom before taking it again to service? what really happens if phone shows different S/N? again, thanks.
hi all,
can anyone point me in the direction of a stock rom/guide for GT-i9300 on EE uk, ive tried quite a lot of places but the links are very dated (i.e 2013)
i need to reflash my phone cuz my signal is messed up due to an unknown reason, think imay of messed somethin up in the field test menu
any help would be greatly appreciated
The dated ones work as well.
Just grab the latest stock ROM for your device at sammobile website and follow the steps
Thanks a lot conanDO, i was gonna wipe the phone as a last resort.
Came across a thread sayin to flash a patched modem as the efs may be damaged (not 100% what that is atm)
But i done it and BAM back on the network.
Thanks a lot either way for your input
