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.
hi there note 3 user.. my friend used odin to flash his note 3 n9005 from kitkat to the official lollipop and when its about to finish. it failed so then he flash back to stock kitkat but then the imei baseband was gone! and the phone very lagging and keep reboots and looping at the start screen showing galaxy note 3.. there was no sound and camera too.. anyone can help out here? i googled and searched all the ways of fixing already still no luck.. and he doesnt have an efs backup.

!! Sm-n900k !! Imei null / baseband unknow / sw rev check failed fused 4 > binary 3
Hi Guys!
I have a SM-N900K (KT version - South Korea) Galaxy Note 3. I upgraded it to Lollipop 5.0.1 and now IMEI is NULL. I can not fix it. I don't have any EFS backup.
I tried to downgrade by flashing stock 4.4.2 rom : N900KKKUENF2_N900KKTTENF2_N900KKKUENF1_HOME.tar.md5 but got error: SW Rev Check Failed Fused 4 > Binary 3.
I flashed with Stock 5.0 Rom: ALL_KTT_N900KKKU0GOC4_N900KKTT0GOC4_CL4362511_QB4250245_REV00_user_low_ship_MULTI_CERT.tar.md5 and another Rom: GALAXY_NOTE3_N900K_SPACEX_LOLLIPOP_MANHIT.tar.md5 but still same IMEI Problem!!!
There are not much Custom Rom for SM-N900K. So I tried to flash Sm-N9005 Custom Roms but there are always "Could not do normal boot!" problem.
I live in TURKEY! So I can't send the phone to South Korea. I gave my phone to a phone repairman. He couldn't fix it, even if he used up-to-date box.
I also looked for how to unlock bootloader. But there is none as I saw.
Please help me guys. I couldn't downgrade to 4.4.2 KitKat and still have IMEI null problem.
Thanks in advance...

Why did you flash other variants roms? Because if you flashed right rom it would not brick it and lose imei.
Have you tried efs recovery method somewhere here at q&a forum?

I have same issues, but cannot find the way to fix it. Did you fixed it, can you share ?
Thanks
I had this problem 3 or 4 years ago. I found the solution that time. The solution to this problem is kernel if I remember correctly. You have to find a suitable kernel. When you find a suitable kernel for sm-n900k you can use many custom rooms.
Another thing is;
You have to install a custom rom then before starting the phone, flash suitable kernel and the you are good to go.
I hope this information helps you.
Hello friends, I need some help.
I was replacing the firmware of a Galaxy Note 4 (SM-N910C). Unfortunately something was wrong with the update and I lost the IMEI. I did not back up. Well I was already used to doing with the S4 Galaxy and I never had a problem.
The firmware he was on was 5.1.1 and the rom I loaded was CyanogenMod 13.
I would like to count on your help to find a solution to the problem

Try to flash the stock modem.
You should have backed up the efs in twrp.

Hi All,
I have a newly refurbished Korean samsung galaxy s4 LTE active (LGU) SHV-E330L with baseband E330LKLUDPH1. It heats up heavily and have battery draining issue due to wifi reconnection and mobile signal searching in countries like India, pakistan and Bangladesh. Also, it does not have LTE band 3 support which is usually available in the international version i9505 or i9506 of the same device and is also supported by the chipset.
I updated the device with custom ROMs but it could not change the baseband, if I try official firmware, I get fail : auth error in odin along with secure check fail for: aboot.
I also tried flashing bootloader and modem from i9505 and i9506 only but could not change the baseband and get the same auth error.
I also tried NV writing to NV item 6828 but it gave success message only but did not update the values, as I checked by backing up again.
Currently I have twrp recovery installed along with 6.0.1 marshmallow and it shows model SM-G900M galaxy s5 but still all those problem exist.
My questions are :
1. Is it possible to change baseband? How ?
2. Is there any stable baseband for galaxy s4 without any issues?
3. Will it softbrick the device if I update the bootloader and modem now?
4. How do I backup/restore/flash modem or bootloader using TWRP ?
You cannot cross-flash the bootloader from another s4 to this phone using Odin. Also, cross-flashing the bootloader could hard-brick the phone.

Thanks for replying .
with Heimdall , is it possible ?
I can leave alone the boot loader , I only want to flash compatible modem.bin and non HLOS bin .
Do you know a way to fix this ?
I have tried many custom roms but none seem to help about network .

Really?
You can only flash firmware from the same model as your device.

I don't recommend cross-flashing modems either and an incompatible bootloader/modem could hard brick the phone.

Thanks for your reply .
Hi , I understand , it can brick the phone but how do I resolve the problem ? if not the boot loader but a compatible modem firmware such as international version of GT-i9506 could help ? Is there a compatible modem software other than the original firmware ?
As I stated my problems clearly in the original post, I have several problems with device software as i think they are software problems.
Is there any fix or solution for that other than what I tried ?

1. You can only flash a baseband that applies to your device. Attempting to flash other basebands will fail and could damage the device, as @audit13 mentioned. As @krasCGQ makes clear, using Heimdall instead of Odin won't change this fact.
2. There may be other basebands available for your device, but that requires downloading the ROMs from sammobile or samsung-updates and extracting modem.bin and NON-HLOS.bin from them.
3. Updating the bootloader and the modem won't brick the device, so long as they are for your device. For example, you can flash an I9505 modem and baseband on any I9505, but cannot flash the same baseband and modem on an I9500.
4. You don't. You need Wanam Partition Backup and Restore to back up the modem partition. Backup up the bootloader you can do as well, but there's no point to it.
You asked how to resolve the battery drain and your other issues. Start downloading older ROMs and trying to flash their basebands until you find one that works well for you. Since you cannot flash basebands from other devices onto yours this is the only viable software solution other than "sucking up and dealing" with it. To answer your most recent question, changing the motherboard could in fact solve the issue, but like the basebands, the hardware is specific from one model to another. For example, you cannot place an I9505 motherboard in an I9500 device. You would need to purchase a SHV-E330L motherboard.

Thanks for the reply.
1. I9500 has different Chipset but i9506 has same as SHV-e330L . I understand the risk. My question is are you aware of compatible basebands for shv e330l other than original ?
2. I backed up using twrp recovery including bootloader, modem and efs, is it sufficient or do I still need Wanam Partition Backup ?
I will try older basebands for the same too.
One thing strange, originally , NV 6828 bit for original device should have been 15 for 1+3+5 LTE but are (08 10 00 ) band 4 + 13 LTE .
1. Chipset is irrelevant. If the baseband isn't for your model of S4 you will not be able to install it.
2. TWRP doesn't back up modem partitions at all, because the partitions in question cannot be seen by TWRP. Wanam is required.
I never was able to add bands to my I9505 and nearly bricked the device in trying it. I would stop trying to add bands.
