Problem to configure LTE after flashed new ROM(

Hello ,All
i am new to this experience and need help here.
I have recently flashed S6 PORT by Albe95 over my Galaxy S4 ,baseband V # I337MVLUEMK6 (Fido). Every are allright except could not endable LTE .after input all infos requires it allways got message the current profile is blocked .what should ido?
thx

Have you tried updating the baseband?

No.and how to do it?

The simplest way would be to flash the latest stock ROM from sammobile.com, then install TWRP, then flash the ROM.

Ok thank .will try

I am having a similar problem. Ever since I upgraded to Goldeneye my LTE coverage is not as good as it had been.
Does this sound like a baseband issue? Would appreciate guidance on how to check that?

It could be a baseband issue. How was signal quality on a stock rom? If it was fine, it sounds like it is a rom issue.
You may also want to try upgrading to the newest bootloader and modem too. Update options for the i337 and i337m will vary.

galaxy j500h 5.1.1 downgrade problem

okay so i have this lil problem on my galaxy j5
a few months ago ive found this thread: https://forum.xda-developers.com/galaxy-j5/how-to/tutorial-upgrade-j5-2015-to-6-0-t3443904 so i tried to upgrade my phone to android 6.0.1(firmware: http://updato.com/firmware-archive-select-model?record=D2F21816700B11E69B2DFA163EE8F90B) and it works perfectly fine tho
but im trying to downgrade to 5.1.1 coz i cant install any custom mods and kernels so i tried to flash a android 5.1.1 firmware(http://updato.com/firmware-archive-select-model?record=F33B6BD4400411E6815B0CC47A44B7B2) which it gave me bootloops
i tried to re-flash it to android 6.0.1 firmware i recently downloaded. it works and it starts up ok but it says that the system is not running and it should be factory reset--something like that. so ive factory reset my phone and again..it gave me bootloops
fortunately ive recently did some twrp backup and good thing it worked fine. but the problem is that the recovery didnt backup my phone password(which im stucked rn bcoz i cant type my main phone password)
im preety stuck here and if i factory reset again it still gives me bootloops
pls bear with me if you dont really understand my problem(im not that fluent in english)

I dont own that device, but i thing this would work:
Flash latest 6.0 firmware with samsung smart swich (PC), enable oem unlock in settings, flash twrp for 6.0 with latest odin, do a factory reset and a full wipe (except external sd an android secure). Then download latest 5.1 firmware for your device an flash it with odin (it will take some time).

You are stuck on Marshmallow

Hai bro,,,
u try this one after flashing offical firmware simply reboot your device into recovery mode by pressing Power + Home + Volume UP and do a wipe data/factory reset, and wipe cache partitions then reboot your device, it will start properly and all problems are now solved,,,,,

With the J500H, Samsung decided to lock the bootloader, meaning you can't downgrade. J500h seems to be the only locked device. Unless someone finds a way to unlock the bootloader then you are stuck on 6.0.1.

You can't downgrade anymore. I have J500H too. Im using Custom ROM right now.
More info here: https://forum.xda-developers.com/galaxy-j5/how-to/warning-flash-marshmallow-updates-t3500396

There is no solution.

update: after spending days of searching from google, i found a 5.1.1 firmware that is compatible with my 6.0.1 firmware since they have nearly similar baseband versions(J500HXWU1APE5 for the lolipop and J500HXWU1BPG1 for marshmallow). so now i can upgrade and downgrade the phone's firmware with ease

please, help me.

u can show me. how to flash with odin (

Firmware downgrade Samsung J500H from MarshMallow with the second loader to LP.
Those who are faced with the inability to roll back to version 5.1.1 are uncomfortable with using their phone.
We need to either use the Philippine firmware or install a custom firmware Belousova.
I found an acceptable way to flash my phone with a stock firmware.
For rollback, we need a four-file stock firmware J500HXXU1APA5 or J500HXXS1APE1.
File BL with the second loader BL_J500HXXU1APA5_CL958143_QB8363487_REV00_user_low_ship_MULTI_CERT.tar or BL_J500HXXS1APE1_CL1011281_QB9453563_REV00_user_low_ship_MULTI_CERT.tar .
Odin.exe.

5.1.1: https://samsung-firmware.org/download/Galaxy__J5__/zvs5/MBC/J500HXWU1APE5/J500HMBC1APE5/

First update to MM have the some botloader like LP. But next update have other bootloader and you can't boot LP with odin to your telephon.
10:32 And some more - Philippines firmware LP 5.1.1 have second bootloader. You can downgrade from last update MM to LP 5.1.1 very easy.

I found how I can help for you.
You may download firmware from here :"goo.gl/Yk1Byz" and unzip and flash in odin this firmware.
Then if some hardware not working you may download firmware for your region from here:"goo.gl/SdcwhA"
and unzip repeat the flash with odin but with one file firmware.
And If you don't update your telephon to MM you can flash telephon using only this stock firmware. Save it. First file you can delete.
I am sorry - in first step you may set BL for APE1 file from my blog . It have second bootloader for firmware.

Lenovo Z2 Plus/ZUK Z2 Plus Baseband Update Guide(Keeping Bootloader Unlocked)

Q. Whats Baseband?
Baseband in laymans terms refers to the radio drivers or blobs of the device.
Many users have complained of their bootloader getting relocked after updating their baseband through a zip file through TWRP or even through fastboot
This guide is for updating the baseband through fastboot WITHOUT RELOCKING THE BOOTLOADER
Using this Method Wont Touch Your Bootloader Keeping it AS IT IS (In the same state as without flashing this baseband)
Many a times after updating baseband or restoring firmware backup through TWRP we cant hear sound or the reciever cant hear us during calls OR sometimes in your custom ROM or sometimes even in latest ZUI you cant get VOLTE working despite all correct APN settings
If you face this problem then updating your Baseband will Solve the Problem Most Of the Times
DO NOT USE THIS ON MARSHMALLOW STOCK ROM OR MARSHMALLOW BASED CUSTOM ROMS IT WILL CAUSE PROBLEMS
USE THIS ON NOUGAT STOCK ROM OR NOUGAT/OREO BASED CUSTOM ROMS
CAN BE USED WITH LOCKED BOOTLOADER ON STOCK ROMS
If TWRP is installed then take a backup of your efs partitiom
Using This Tool Will update the Baseband to M8996FAAAANAZM-1.76387.1.92759.1 (Latest Nougat Baseband)
1.First download the tool from this link https://drive.google.com/file/d/0B2CgYqnPbCh_Q2N0Vmd1d00ySFk/view
2.Download and unpack archive
3.Load the phone into fastboot mode.
4.Connect to PC.
5.In the folder with the unpacked package: Run cmd and then flash_radios.bat - follow instruction on screen.
6.Reboot.
For Installation without PC flash this zip file by davide which i have edited so that it doesnt lock the bootloader or change the splash image, using custom recovery.

If u don't need volte than u can dirty flash baseband on any rom naugat or oreo.
But i think volte is gone because baseband is being flashed with some errors. So it can cause problems like signal fluctuations and wifi instability..

For those who getting volte and calling voice bugs...
Flash deodex zui 2.5 indian ..
How i solve my prob
Basically i try oxygen os marshmallow based rom(which degrade my baseband to a mm one) and then i restore my naugat twrp backup....then the voice bug happen.....
Then i flash the latest indian baseband from zuk fans forum....on my custom naugat rom(viper os)
After flashing voice bugs gone...but my volte stops working....
Then i flash deodex stock zui 2.5 indian and enable volte(volte works at this stage) and then flash my custom naugat again ...and everything is fine
SO THE STEPS ARE
1..Flash baseband ..then check if everything works fine or not(basically check ur volte and voice call)
If not then follow step 2
2..Flash stock zui2.5 indian....after zui flashing check everything will be working great ..(don't forget to enable volte in stock)
3...Now its upon u whether to flah custom or not
..................ENJOY.................
NOTE: MY DATA IS SAFE...BY ABOVE STEPS U WILL NOT LOOSE UR DATA
M giving some reference link down below hope i helped u

If you already flashed the baseband then you don't need to flash it again, if volte doesn't work for you then you can flash baseband and clear modemst1 and 2 yourself and clean flash rom/gapps/magisk.

Thanx, I'll do like you said.
I occasionally loose signal bars, then I can't receive and send calls. It's just for few seconds, but it's still annoying coz I have too much calls with partners on my work.

Works like charm!
I'm running AOSP Extended 5.0 Latest Build by @davidevinavil . I just downloaded, unpacked archive, rebooted phone in fastboot mode, connected to my PC (USB 2.0), and ran .bat file as administrator, disconnected phone and restart. Everything is working. Thank you dev for this guide! :good: PS. Not a Jio user so no idea if VoLTE works. WiFi, 4G, Calls work flawless.

UPDATE. I'm using Vodafone (Mumbai Suburbs) and after updating baseband, I'm getting faster webpage loading speeds than before.

For Changing Baseband Without PC Flash this zip by davide which I have edited so that it wont relock the bootloader or change the splash image. Baseband version 2.0
https://drive.google.com/file/d/1mHdf2kc0ARpRO6kxAKiI3dotAVY0TJdM/view?usp=drivesdk

calling issues: receiver cant able to hear me properly
First i flashed stock (nougat) ZUI_2.5.104_ST (Indian) volte was working fine calling was perfect on both sims.
Then i flashed aex 4.6 i checked the baseband it was version 1.7 (previously it was 1.6).
Volte is not showing then i have to manually add the apn then volte was there.

Uncommon behavior when flashing custom ROM - Please help :)

First of all hello to everyone!
I have quite weird problem:
I have my phone rooted and customized since day one - Installed KitKat, tried some launchers, unlocked UPSM and so on.
It ran flawlessly for nearly 4 years.
Recently, for no particular reason I decided to wipe&refresh it and maybe install some totally custom ROM.
NOW: I can install ROMS like Lineage 14.1, 15.1 or Resurrection Remix 6.0 and they run fine except (yes, You probably guessed it) they mess up baseband and IMEI.
I can still revert to original 4.4.2 stock ROM and both baseband and IMEI work fine so i'm not in any "brick panic"
The point is I still want to move to some custom ROM but can't sort out baseband-modem and IMEI problem.
I tried to flash several different modems to no avail - sometimes (totally randomly) IMEI showed up on first boot after flashing but was gone after reboot.
- On my current 4.4.2 stock, IMEI shows up correctly NO MATTER which modem version I flash (is it weird or normal or what?)
- none of modem versions work on Lineage OS nor RR
- SIM card works flawlessly on all other devices and on my current 4.4.2 ROM so it's not damaged.
Is it matter of proper custom ROM+MODEM combination or something else?
Can anyone help to sort it out?
What more information do You need?
Thanks in advance!

Flash the latest lollipop stock firmware to update your bootloader.

Yeah, meanwhile I did flash lollipop an hour ago and it works fine with IMEI and all.
Latest version I could find for my phone was Lollipop 5.0
How can I tell if bootloader is updated?
Can I Flash sole bootloader independently via Odin?

Yes you can. Go to this thread https://forum.xda-developers.com/galaxy-note-3/general/bootloader-baseband-bl-cp-samsung-t3582504

Thank You all for help and pointing to right direction!
Taking care of proper bootloader version was the key step that sorted things out.
Now I'm enjoying superlite bloatware free 8.1 oreo with LineageOS 15.1 on great 4 yrs old device.
And it works super smooth. Way better then original 4.4.2.
Now I'm being tempted to push the limits and try 9.0 Pie with LOS 16...

Whenever flashing a stock ROM with Odin, the stock ROM includes a bootloader and modem file.

Hi everyone,

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:

rebooted to check if everything was working using stock before going to custom...and...
it started overheating as soon as i tuned on wifi. i only managed to install phoneinfo to check wich modem i have as you suggested, then i had to turn the phone off it off cause it became reeally hot and i thought i could break it. modem chip is "mdm9215m". any suggestion? maybe i should try to instale all the lollipop modems / bootloaders from your post...

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.
