Hi,
I'm currently having a problem with m N910G Note 4. The baseband version is Unknown. This happened after flashing Norma N7 V12 and different bootloaders and modems for Marshmallow (can't find the G1 BL recommended for the ROM). I had a backup for my Lollipop rooted stock ROM, except data. It has Modem and EFS backed up as well so I restored all.
However, I'm stuck with my phone freezing and rebooting (mainly due to baseband issue). I tried loading different bootloaders and modems available for N910G Lollipop but to no avail.
If anyone knows where I can get the COI1 BL and CP, that'd be great so I can still use my backed up ROM. Else, I might have to stick with upgrading to Marshmallow (since that's the only available free firmware on Sammobile). I'm avoiding upgrading the firmware though due to eMMC issues that mostly occured on Marshmallow.
Thanks,
Vin
Flashed RR 6.0.0 Android 8.1. ROM recognizes the bootloader and modem so no more rebooting. I guess the TouchWiz ROM has to match with the bootloader and modem; else it'd keep on rebooting. I'd have to find the bootloader and modem for Norma N7 though, so I hope someone could still reply here. Thanks a lot XDA peeps!

Yesterday I've tried to switch ROMs from Cyanogenmod nightly (camera was crashing) to AOSP 4.4.2. AOSP ROM had some problem with CWM 6.0.4.7 (Status 7 error) and when I reverted to Cyanogenmod I had no gsm service. Flashing modem from newest samsung firmware available resulted in working GSM, but I've lost all sound!.
Then I've found out that for older bootloaders I should flash other modem file and I've managed to get sound to work. Now I'm back on Cyanogenmod 11 Nightly and suprisingly, camera works! I suspect that newer modem file I've flashed with Odin fixed camera/cyanogenmod problems.
My first question is:
Should I try to find newest knox-free bootloader and update to it? Is it possible that new ROMs will be working better with newer bootloader?
If so, can you point me to the latest knox-free bootloader?
Second question:
My is taken from firmware for "Open Europe". Since I live in Poland, will I benefit in any way from switching to XEO modem (firmware for Poland)?
I wanted to install Alliance Rom for Note 4. I am running Lollipop from Three UK and I have rooted my phone and installed TWRP. I backed up my modem before installing a new modem recommended to install Alliance Rom. BOB4. But I cannot get my phone passed the bootloop even after restoring my backup. Please help.
Non hsl modem file? And many having problems with this cuz different bootloader. I general tip are to first flash latest stock firmware so you get all modems and bootloader. Then flash lp custom rom. Look at sammobile page
What is CP on Odin? If I tell you my Samsung info, can you tell me if I can install Alliance Rom lollipop. I am note sure because my CSC is BOB2
I am on a quite old bootloader and modem as I have not ran any new Roms, or updates to my phone in quite awhile. I was going to try out a new 5.0.1 rom (I am on 4.4.2 now) and was not sure if I would need to update my modem and/or bootloader before I do so.
On SamMobile there is certainly new firmware for my model and carrier, so I was considering flashing the modem and bootloader thru Odin before I try a 5.0.1 rom. Is this recommended/necessary? By flashing a new bootloader, will I lose root or my ability to flash custom roms/kernals/etc?
I tried googling and searching on here first, but could not quite fine the answer. Thank you for any help or guidance.
If you're going to flash a 5.0 touchwiz rom it will update the modem and bootloader I think.
Updating them is not necessary.
People say that flashing newer modems will give you a better signal reception. I have yet to see that "better" signal reception.
You won't lose the ability to flash stuff.
You will only lose root if you flash a stock Samsung rom.
Hi, I have recently rooted and bootloader unlocked a G900V and it works fine on Lollipop roms, but when the device is flashed with a MM rom via TWRP or Flashfire the Wifi wont work. IDK what is up with this. Maybe it has something to do with the baseband or whatnot, I'm out of ideas so I have to bug you guys for help, thanks in advance!
A little more Info I'm on PF4 baseband. Tried the Note5 port rom, the BS free rom and a deodexed debloated MM rom and all have no wifi. Ive tried the phoenix kernel, still no go. Tried flashing the PD1 baseband as its another MM baseband and it didnt take (via odin or TWRP ¯\_(ツ)_/¯) . So idk why flashing basebands doesn't work, maybe it'd solve my problem.
By using Getex's [GUIDE] Unlocking the Galaxys S5 Bootloader using DEV Bootloader [KK-MM]
and following the bottom subsection (If You Already Have Bootloader Unlocked And On A Samsung TW Rom) I was able to fix the problem.
Nice! Thanks GETEX!
I have an EUI 5.8.21s stock ROM zip, flashable with TWRP, from x727 (modded for dual sim x720, but can be modded back) I also have a modem for 19s. I hear the latter will fix my issues with my phone under custom ROMs, but am a bit nervous about modem flashing. My phone came with stock 18s and no OTA upgrade available.
Will the stock ROM also fix this, and also, will it relock the bootloader? If it relocks the bootloader, can I flash the 19s file that unlocks the bootloader without side-effects for custom ROMs or it not unlocking the bootloader?
I know this is a lot of questions, you don't have to answer all of them, just answer with the right solution for this problem.
I went ahead and flashed the modem... hope this solves my issues.
It didn't solve the issues. What now? Is the stock ROM I found here, mentioned above, bootloader-unlockable or will it trap me in it? I think I want to give it a try, but want to go to custom ROMs; perhaps afterwards if the modem/baseband on it help.
i had a similar (but not same) question like this.
You can try to flash CN stock rom and then reflash US modem. The US modem can be found in many threads.
BTW, i did not notice anybody post a modem file with a 'newer' version no.
