Null IMEI and Unknown Baseband on SM-N9005 - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello All,
Please forgive me if this is the wrong area to post this, this is my first post here.
I have a Galaxy Note 3 SM-N9005 that I purchased. The previous owner had it rooted and the leaked Lollipop 5.0 installed. I tried to flash it back to stock (Australian) however it near bricked it. It was running really slow, a hell of a lot of lagging. I installed the DirtyUnicorn Lollipop 5.0 custom rom, and the phone runs fine, except for the fact it has no radio (i.e. no 4G/3G/2G connectivity and no telephony).
I searched for days and days on end looking for a modem/baseband compatible but nothing seems to work. Would anyone have any info on how to get the radio working? I really don't care about going back to full stock, as long as I can use the radio. I have included some photos of the system info and the sticker under the battery.
Thanks for your help,
Christopher H.

[Q] How to recover IMEI? - - Help please!

Hello!
I have a Galaxy S3 currently running Paranoid Android 3.99-RC1. I just flashed this today from Cyanogenmod and everything went pretty smoothly except that when I was setting up the phone there was no mobile network. I investigated and the Baseband version is Unknown and I can not do anything else with my phone.
I have looked everywhere on what to do, but I am not 100% sure and would appreciate some guidance.
Should I just go ahead and flash the stock rom to backup imei and efs folder? - I don't think I did this before.
With Root Browser I did find this: efs folder --> imei folder ---> mps_code.dat
When I do the *#06# IMEI is blank.
Thanks.
Switch to TWRP recovery and flash the ROM again

The post above me won't help. I had the EXACT same problem. Switched from CM to PA 3.99 RC2 for my GS3 AT&T.
Odin flash the stock ROM for your specific device. Essentially un-root it. Then you will have to re-root it.
This is pretty much guaranteed to work.
Good luck. Sorry, it is a bit of a process. Finding the stock rom can be slightly annoying too.
i9305 not support (hope - only at the moment)
Hello, I also had the problem with my SG3 - i9305, but didn't figure out how to solve that "no baseband problem".
Tried different basebands, flashed from different recoverys (TWRP, new and older versions, same with CWM), finally gave up and went back to PA3.65 wich worked so far (luckily I had a working backup copy).
Do you have an i9300 or i9305 ?
So - for the i9305 thinks look bad, 'cause the developer has stoped this...
you can have a look at this thread for some reasons...

Slow Internet (3G/LTE) after 4.4.2 Update

Hello Guys
Well, let me get straight to the point. After my old rom (Revolution HD3) was draining my battery pretty fast, i decided to update to 4.4.2. Well, i downloaded the latest 4.4.2 for switzerland from sammobile.com. I flashed it and it somehow was all laggy and i had fc's the whole time. After some time i was able to use the phone anyway, but it was laggy. And the problem was that my 3G connection was EXTREMELY slow. I got connection time outs the whole time and wasnt able to download anything. Well, i thought it was the rom i flashed trough odin, so i downgraded to 4.2.2, my original rom, and updated trough KIES. The rom wasnt laggy anymore, but the 3g/4g was slow. I tried different Modems and Kernels. Nothing Helped. I then decided im going back to a custom rom but the flash failed. Then i tried another rom and it failed again. So i thought it may was cause i was on 4.4.2 and tried to flash a custom rom that was 4.2.2. I then tried to reflash my stock rom trough odin, and it FAILED. And that's how i bricked my phone. I can still enter Download Mode, but can't enter the recovery anymore. What do i do? I'd like to solve both problems.
Thanks guys
Btw: I've got an I9505
I assume you didn't wipe anything before you flashed stuff? Thats like rule number 1 to do.
You can try flashing a recovery true Odin.
Hej Guys
Um.. Just to let you guys know, it is possible to downgrad to 4.2.2 from 4.4.2. I just did it this morning and had sucess. But the problem with the really slow internet connction still is here, when im on a 4.4.2. And, it is the same with custom roms running 4.4.2. I tried different kernels and modems, nothing helped so far. As soon as i was back to 4.2.2 it had the usual connection speed. I called my provider and also called samsung itself. Obviously, they both told me to bring the phone back for garantuee. But well, as i know it's a software problem and not hardware, i wont do that. So can you guys help me? What should i do next? Actually im back on 4.2.2. Thanks
Edit: Oh, and ofc, i did everything like wiping/factory resetting, wipping preoload etc. It's not my first time flashing.
It's not possible to downgrade from 4.4.2 to 4.2.2! End of..

Are you serious dude? Im running 4.2.2 right now. What is your point?`I didnt even ask about it. I asked about a solution to the problem that i get slow 3G/4G on my I9505 when running 4.4.2. If you want a proof Pic about it running 4.2.2, i can give you one. But i dont really get what your point is.
Hang on hang on hang on, it is common knowledge that you cannot downgrade from official samsung 4.4.2 to official samsung 4.2.2 because in odin you will get failure at aboot.bin because you cannot downgrade bootloader.
How ever what would be really good is instead of just trying to say it then jumping out saying what's your point, we'll my friend the point is, it would be advantageous to everyone in the entire samsung galaxy s4 i9505 community if you can tell everyone how you did it.
My perspective is your doing a bit of flaming.
Pictures really won't prove a whole lot as anyone can do some build.prop edits and show different rom name and version.

Well, if it sounded like flame to you, it wasnt. I didnt create this thread to flame others. But i wasnt kidding saying that i downgraded to 4.2.2. Here how i did it:
Was running 4.4.2 (I9505XXUFNB9)
Flashed TWRP recovery.
Flashed custom Rom 4.2.2, which FAILED!
Flashed Official 4.2.2 trough odin, which FAILED!
Flashed TWRP recovery again, since it was somehow damaged from the flash before
Flashed Wanamlite 4.4.2
Flashed Custom Rom 4.2.2
Flashed Official 4.2.2 with succes.
Im not sure what part of those flashes were essential, but i have no reason for liying to you. What would be the perks if i did?
But now again BTT, Did anyone else have that problem of slow interenet connection? Or is it just me? Maybe some ideas?
Regarding slow Internet maybe it's your carrier with issues.
Maybe the downgrade back to 4.2.2 has created issues in its self. Have you checked your baseband matches bootloader and build?
A problem we have is we can't see the version of the 4G modem (non-hols) so that might be also an issue.
When you flashed back did you do a factory reset?
In regards to downgrade do you still have the Knox bootloader?

Well, i called my operator and the girl on the phone said that some people already called with the same issue, but its not on their side. It's a problem with the update samsung released. After the downgrade i had my Knox Bootloader and everything worked like it always did.
Yesterday Sammobile released a new ''rom'' for my country. Downloaded it, flashed it and it works great now. I have a bit of a fast battery Drain, but the problem with the slow internet seems to be fixed.
Again: 4.2.2 worked perfectly after downgrade. It had no issue, No FC nothing at all. Maybe i was lucky? No idea, but im happy my 4.4.2 works now
Thanks anyway for your help guys
Edit: Yeah, my bootloader matched both baseband and build.

If you had done your homework, you would know that in almost all cases Samsung repairs it even with Knox set to 0x1. They even publicly stated it in the Netherlands that they will repair your phone even with custom roms.
And you don't know the law in Switserland. Nor do I. So you can't say that in Switserland his rights are voided by flashing.
If Samsung doesn't give you the warranty, then you still have your consumer rights in the European Union (not that Switerland is in it). No flashing, modding or other chances decleine you your rights if it's not related to a hardware failure. In the countries that you and I live in, it will never void your rights if the damage is not related to flashing or modding.
So well, i think that in switzerland they actually WONT repair it if you flash it, but i aint sure about that, since i never had to send it to repair. But anyway, it was only a software problem on their side. They released another version for switzerland and it seemed to have fixed the problem. I have a bit more of a battery drain, but i actually think im just too used to some other custom roms. Anyways, thanks for the help guys

Galaxy S4 without network signal. Please help.

First, I have a Galaxy S4 i9505 (4G), the problem does not affect my device, but the device's my cousin who is a Samsung Galaxy S4 i9500 (3G).
He recently purchased the unit from another person, the unit worked well, but had a small defect in the charging connector ...
He asked me to sell one of my cases and battery why his battery was apparently bad, why was not possible give loads on the battery, I managed to solve this problem.
The problem came when he asked me to update the device to Android 4.4.2 KitKat by several improvements, I downloaded the latest firmware available at SamMobile site and after that did the flash using Odin.
Knox had in 0x1 (the unit had been modified) and I read on some forums that night, that when doing upgrade directly from 4.2.2 version, especially XXUBMGA the EFS partition changes shape, thus having little network problem and signal.
Link : http://www.grupoandroid.com/topic/83400-modem-mg9-y-posteriores-modifican-la-efs/
My questions are, it is possible to resolve this situation? I read previously that the IMEI is restored from a backup made previously it is possible to recover the network signal, but made no backup of EFS ....
I also read a long time ago that it is impossible to downgrade to ROM's with lower versions if there Knox installed.
I did the update of Android 4.2.2 to 4.4.2 using Odin.
If possible downgrade, any of you can share the ROM XXUBMGA 4.2.2 for S4 i9500? Or tell me some possible solution installing another ROM / modem?
I am currently trying different modems and using the OmegaROM in my cousin's S4.
Thx
Extract the modem.bin file from the ROM download and flash that through Odin to correct this. Or simply flash the ROM itself again if you don't want to go through the hassle of getting just the modem file out of the download. Either option will restore the network.
The IMEI in this case likely has nothing to do with the problem you're having, unless the IMEI reports itself as null or starts with 049. If you want a proper backup of the IMEI, you want to download AntaresOne's backup tool from the I9505 Development subforum and follow his instructions to make the backup.

Samsung Galaxy S4 LTE Modem Baseband flash with Odin

Hello guys,
I am verry sorry to bother you with this, but I am just to dumb for this part.
I am quite familiar with the whole custom rom business but I try to fix my mothers phone where I installed a Cyanogenmod custom rom (12.1) some time ago.
She experiences some mobile network issues which, I guess, are related to a old baseband / modem version causing troubles.
Can you tell me which version is the right one to flash via Odin or preferably via twrp?
I plan on updating it before installing the lastest 12.1 CM snapshot.
I believe she has the Samsung Galaxy S4 I9505 International with LTE and Snapdragon processor.
Under baseband version ("About the phone") it says I9505XXUEML6.
(I dont know if this is correct I can remember that I once installed a Google Play Edition Rom to get rid of the bloatware).
The phone was bought in Germany.
I know that you guys are probably busy with more important stuff but I'd really appreciate it if you could quickly help me with that.
Have a great day.
Thank you in advance.
Update: I got the files, changed the cable Odin passed but no version change!
Update 2:
Manually going into fastboot instead of using the reboot menu did it! Thank you so much. (Maybe add that info to the guide to avoid similar problems with othe people)
Thumbs up & good night!

Need help with a galaxy s4 gt-i9505

Hi everyone,
just a long-time forum-lurker in the dark here, now I'm here asking for help to restore my galaxy s4.
Here's the story:
gt-i9505 no brand, italian official firmware 4.4.4 (kitkat), never updated, only used towelroot to gain rood adn unistall couple of unused apps.
everything worked fine
Then i decided to upgrade to lollipop.
downloaded last samsung lollipop rom for my phone from sammobile, made a full backup via TWRP Recovery, and installed lollipop via Odin.
Then the nightmare begun :
1st problem, no modem, no connection, only wifi, i restored EFS, still not working, reinstalled modem via odin and then i got my imei and connection again.
2) think i've tried to change the rom to a custom downloaded here (i don't even remember the name), then i tried couple other roms.
this as far as i remember
Now the phone has a samsung original lollipop rom, wifi won't turn on, data not working, knox status is obviously altered (so i cannot restore it via kies or whatever the software name is now) BUT It overheats a lot after few minutes and i'm forced to shut it off to not damage it.
I'd like to restore it to a full working condition, i think i've messed up with bootloaders, modems and roms from different android versions.
can anyone help ?

Hey, @dokrobei
Take a look on my Guide.
You need the guide clean install from the scratch. Please read it carefully till the end. There avaible links with all necessary stuff like modem/bootloaders/stock rom-firmware/recommend customs roms etc.
Hi @Retrial, thanks for the answer..
I've managed to reinstall stock KitKat 4.4.2 and working modem drivers, following another tutorial here. Now Wi-Fi, 3g and bt works fine, BUT the phone overheats a lot. It's not a battery problem and sure it's software related 'cause it wasn't like this before my stupid first attempt to upgrade to lollipop.
I've searched the forum for the overtheating near the flash zone problem, some say that is a microsd problem (wich I removed), some other that's a battery problem (wich is not in my case).
Do you think I should start from scratch again following your guide? IHow do I know wich modem / bootloader is right for my phone? I think the problem is there, maybe wrong modem version..

First of all there is no need to still be on KitKat...a lot of apps don't support Kitkat nowdays...and is outdated.
I will recommend first to proper upgrade to Lollipop stock and then use some of the latest android Pie Custom JDC Roms by following my complete guide. As I said above there is a full guide with links and very well explained steps. The latest Firmware for our S4 i9505 is QK1 - No matter which country you will choose, and it's recommened to have the latest. Just read it carefully till the end and check the asterisks.
The overheating it may be no compatible Modem/Bootloader since you messed up with Lollipop. To check what Modem and Bootloder you can simply install "Device HW Info" or "Phone Info" app and check.
Let me know how it goes, and if you have any question or problem feel free to ask. Good Luck :fingers-crossed:

After every flash the device become hot. Let the rom settle for a while.
If you have PK2 Firmware then you need PK2 Modem and Bootloader. So no, don't try other modem/bootloader.

I flashed it last night and checked if it was working this morning. I'm sure the high temps are not related to the usage or to the battery. It become hot eachtime i turn on wifi. Havent tried with data but I think it will be the same thing.
