[Q] Question about modems - Galaxy S 4 Mini Q&A, Help & Troubleshooting

Hello!
Lately, I have been seeing a lot of talk about modems (mainly in the CarbonRom thread). I never heard of updating them, altough I have experience with rooting/flashing new ROMs/installing custom recoveries on multiple devices.
I saw someone claiming that newer modems are usually better, they would give you better reception and call quality, as well as improving battery life.
So I was thinking if it would be any good if I would flash a new modem on my phone, the current version is I9195XUBMJ7.
Should I keep my current modem? Should I flash Modem-I9195XXUCNE6.tar or Modem-I9195XXUCNF7.tar? And if I do, would I notice any improvement?
I live in Belgium, if that makes any difference. I'm on a recent build of CarbonRom by F4K and my device is the LTE variant (I9195).
Can anyone enlighten me?

Try to find a newer modem that is used in official firmware in your country
Or if not in your country at least close, that will give u better results

Where can I find newer/the newest Modem? And can I flash it with Odin and use it with Liquid Smooth for example?

Look on sammobile.com then extract modem only, arhive it as tar then md5, and flash with Odin 3.10 as "CP"

The thread gives another way of flashing the modem, are both correct? Is there a way to make a backup of the modem in case all goes wrong?

U can flash with any version of Odin
Odin 3.10 worked great for me.
No u can`t backup your modem, if anything goes wrong apply my method above and download a stock rom and take NON-HLOS.bin
Linux:
Code:
unzip *.zip
tar -xvf *.tar.md5
tar -v -H ustar -c NON-HLOS.bin > modem.tar
md5sum -t modem.tar >> modem.tar
mv modem.tar modem.tar.md5
Windows
TAR_MD5_PACKAGER
Extract rom with WinRar/7-Zip place ONLY NON-HLOS.bin inside that program, arhive it as tar and then md5 it. Flash it with Odin

Thanks for your answers! Really appreciate it!

[Q] request: just the t889 modem odin flash file - non cwm versions

In order to save my phone, I need the modem flash for file t889 that can be used with Odin and not CWM. Please advise.
Unzip CWM version , you will have Zimage ( Odin file). If I'm not wrong.

thanks for the suggestion. However, in the zip file there's the modem.bin, and the flash_image file and a folder with other stuff. I am uncertain which one to extract. (yes, I am googling this as I ask.)
the modem.bin file is the one you need. would you mind posting a link to the CWM zip you have of the modem? been looking for it..
My experience with Odin and modem cross-flashing is that is fails before writing anything. (T889-LJ1 on T889, T889V-LJ4 on T889V and so on should work. Other partitions made with this method work flawlessly, so I'm guessing there's an additional check in the bootloader for modem images.)
Anyway, here goes. Those files were made by extracting from their respective Odin images, from Sammobile and tarring with the Cygwin tar binary.

[Q] Advice/Help: Opening and re-pack stock TAR.MD5 file

Hi,
I own a galaxy note 2 lte version. I have a situation where i have to open, delete modem.bin and repack the stock tar.md5 file.
So here is the situation,
I recently flashed a MF2 stock rom from a different region (Portugal) onto my phone. If you guys are aware, the MF2 modem changes the efs partition and hence if I have to go back to an old stock rom the imei will not be recognized. So I have to re flash the mf2 modem to get the imei working else with old modem imei will not be correct.
What I plan to do,
Flash an old stock firmware without modem so that the current modem is retained and I have a valid imei.
I would like to ask you guys if you think it would work and in that case can I, using 7zip, extract the tar.md5 file and delete the modem.bin file and repack it to tar.md5 again to be flashed via odin PDA?
Thanks in advance for the heads up.

I don;t quite understand why would you delete modem, don't you need to flash previous modem version? Isn't it then easier to just flash old modem?

I plan to delete the modem from TAR just because in that case the old modem would be retained.
If you are not much familiar with linux, it will be more difficult for you to unpack, repack and adding tar + md5
Here solution which can be followed by newbie too
-Flash old ROM, (you will lose baseband and IMEI, don't worry)
-Extract new ROM (e.g. mf2) and find modem.bin
-Flash modem.bin with PC odin for 'phone' tab (unstead of PDA we are using for flashing ROM)
-Now you will have baseban and IMEI back
Done.

Thanks a lot for your timely help and concern.
I downloaded the Singapore Starhub MC1 firmware from the sammobile website and flashed it using Odin.
Luckily after flashing and setting up the phone -> the Modem was able to read mt EFS and my IMEI is intact.
Everything is okay. Happy :victory:
Finally, one more question,
If the MF2 Kernel makes changes in the EFS partition, in my case now -> how do you guys think the old MB3's modem was able to read the EFS partition and IMEI without any EFS backup / modem change.

ap: N7105xxdmb3
cp: N7105dxdll1
csc: N7105olbdmc1
May be this scenario limited to N7100
Or mf2 you have flashed still doesn't have kernel that causing efs modification.

[Q] How to 'debrand' the SGH M919?

Hi!
I got a SGH M919 (T-Mobile Samsung Galaxy S4) and I just can not find a stock Samsung ROM for it.
How do I debrand it and bring it to a non-branded version of ROM? I don't prefer custom ROMs so, is there any stock Samsung ROM out there which I can flash on this to get rid of the T-Mobile branding and all its apps?
p.s. I am not sure if this question has been raised before because I browsed through the forums but could not get an answer.
Short answer, yes. You could flash the international I9505 firmware. Just make sure modem and kernel is that of tmobile.
Yes the question have been raised before.
☞ Sent from here☜???
Hey, thanks a lot for the reply!
3 questions:
1. Wont flashing the i9505 firmware brick my phone?
2. How do I use tmobile kernel and modem? Im an uber noob at this so dont know how to do this. Is there any thread on this topic?
3. I have currently unlocked my phone to work on non-T Mobile network with help of a thread I found on xda. Will flashing firmware for i9505 make it locked on tmobile again?

1) i9505 has the same hardware as the m919 so flashing the firmwares won't brick your phone. The radios, modems, etc, those are all different, which is why you need to flash a T-Mobile kernel after you're done flashing the i9505 firmware.
2) You are already on the MK2 modem/bb. You can flash one of the MANY kernels available. Check here and look for the threads that have the [KERNEL] tag in it. Simply download one of them to your phone, go into recovery, click on "Install zip from sdcard" and click on the file you downloaded. Most of the threads have instructions on how to do it if you're not too comfortable.
3) No, unlock is not firmware based. Flash any roms you want, just make sure you flash a tmo kernel afterwards.
Good luck and hope that helps.
Worth noting; whatever ROM you decide to flash, make sure you use a custom recovery to flash and not Odin. The Odin images for other carriers will likely brick the device because they come with the modem, radio, etc.

Thanks a lot! Will make sure of that. Just for my knowledge: I downloaded a carrier-free ROM from samfirmware (I9505XXUEMKF_I9505AUTEML1_AUT - Switzerland) and was going to most likely use CWM to flash it on my cell - will I have an option while flashing to not flash the modem, radio, etc.? Or when I flash, the modem and radio etc. will not be getting flashed automatically? (this might be a dumb question so please bear with me!)

You won't have to worry about it if you're installing the ROM by itself. It won't be affected. As long as you just install a Tmo kernel and the ROM of your choice, you'll be good. The modem and etc are separate unless for some god awful reason the Dev decided to throw it all into one zip. I have never seen this nor do I think it even exists. When installing the ROM you won't have to worry about the modem. Dude, just make sure to do a backup and you'll be fine. Good luck

If the file ends with tar.md5 it's an Odin package and should be avoided. If it ends with .zip though it's CWM-flashable and, speaking for XDA's ROMs, won't include modem, baseband, bootloader, etc.

I actually prefer stock samsung ROMs over customs ROMs so I downloaded the one I mentioned from samfirware.
Now as for flashing a T-Mobile kernel is concerned, I was going through the kernels on xda and they all seem to be custom with tweaks done to the hardware clocks, etc. Is it possible to flash a 'stock' T-Mobile kernel on the 4.3?
Btw, I am not able to flash the stock ROM (in .zip format) that I downloaded from samfirware using CWM. It gives me this error: "Installing update... Installation aborted." How do I flash a stock ROM downloaded from samfirmware (using CWM)? I am being advised not to use ODIN (due modem etc issues), so what do i do? I reiterate, i don't prefer the custom ROMs.

Samfirmware downloads are in zip format and you have to extract them to get the .tar.md5 file. That .tar.md5 file HAS to be done through Odin. You can't use those in CWM. The CWM ones are the ones you find on these forums.

The point I'm trying to get across is to not use Odin to flash anything that's not specifically meant for your device. It looks like he's trying to use the stock Odin-flashable firmwares for the i9505 which would be bad... Any of the CWM-flashable ROMs in the i9505 (not i9500) are good to go.

You are absolutely correct. I don't think he understands the difference between the two... :crying:
Um, guys, my question still seems to be unanswered: since samfirmware roms are not cwm flashable, WHERE do i find non-odin flashable stock rom? Is it even possible? I downloaded samfirmware stock rom because of the very first reply to my thread which mentioned it.
And my second question: is there a stock t mobile kernel i can use instead of the custom 'tweaked' ones?
Forget about the firmware you downloaded from sammobile it will brick your device go to the i9505 section here in XDA and download one from there and then flash it in CWM then the Tmo kernel and your done.

[Q] i9195 upgrade from 4.2.2 to 4.4.2

Hi guys! I have the italian firmware for the i9195, i9195XXUBML4. I have alredy tripped my knox, so i don't care about the warranty...
If i flash the GT-I9195XXUCNH5_R1 deodexed from @ladislav.heller, will i face problem with modem or something else? I already have some experience with my ex s advance and with my current tablet ( tab2) wich are both with cyano, so i can understand something
I cannot try it because if i flash something i want to be sure that it is compatible with my phone, i wouldn't brick it
Sorry for the bad english xD
@Alecotro Before flashing that ROM you must upgrade your modem to cnh5. Links for that modem are on the ROM's thread.
When u download that modem file extract it and flash it with ODIN as PDA / AP. Repeat and verify if your modem changed. Check baseband in settings>about phone for confirmation. Once u are done upgrading the modem u can flash the ROM via custom recovery.
Without modem u will face connectivity issues and force closes. I am using that ROM and it is perfect.

Thank you very much! Will the different modem have problem italian carrier like wind (don't know if you know it)? Cause with my s advance i always had the same baseband whatever the rom i flashed...
And, in the future, if I flash something like cyano, will i have to switch back to my old modem?

If I flash a firmware different from the ITV one, will it be different with signal of Italian carriers?

Modem question

I currently have a m919 and using an AT&T sim. The ROM I'm using is AICP and I'm on the NB4 baseband. I had a problem with my signal strength using the lollipop version of AICP and was told to use the NH7 baseband. But I'm seeing HLOS and Non-HLOS versions both tar and zip files. I'm busting wanting a time that I can flash on my custom recovery that I won't be needing to download a huge factory file that I'll have to flash through Odin. Can someone please give me a link or at least guide me to the right path to take? Thanks in advance!

If I recall correctly, one can extract the modem.bin (modem) and non-hlos.bin (LTE modem) directly from the full stock rom.
