Greetings, sharing here my particular problem from top to bottom just to take advice in general.
First of all, I live in Cuba, so my one and only network is Cubacel which runs GSM 900 mhz, so far so good with most phones.
I am between phones so I boorrowed this used J100h from a friend, which received it as a gift and has never been used. I performed a hard reset to wipe password, data, etc. Phone boots ok but no calls with cuban SIM.
The curious thing is that it does recognizes Cubacel network, it evens shows the changes on signal intensity. Bu when I try to manually add it, it finds and displays the network by its name, but reports an error when trying to register.
After 3 days of internet search I´ve narrowed to the following: I suspect the phone was unlocked or flashed previously, there is no network promo when turning on the phone but there is chinese rooting software installed and the cell is, or seems via root checker, rooted. Thought an extra /01 after the IMEI was a sign of corruption until I leraned about IMEI SV. Anyway, following this thought installed busybox and root explorer, checked efs folder, finding subfolders such as imei, factory app, etc, BUT NO .NV file. inside imei folder ther is a imeino1 file with the correct imei, but no .nv file outside. Is this fixable?? GSII repair doesnt work because seems theres is an error with the busy box install, what gives me doubts if the phone is really rooted, and if i need to be online to install busybox properly.
So, If I decide to try and flash stock rom and see if this fixes the problem here is my main doubt, which may seem obvious for some but i simply can figure out. Which stock rom version do I choose? the product code of the cell is ITV, and the bootloader also points to the italian version but the currently installed rom ends in AOG2, seemingly a greek version. I live in Cuba and everywhere I look people say that since the telephone is sim free you can install any rom, but the is no "any" or standard rom either in samsung firware o sammobile. Do I flash the same rom? do I flash the one matching the bootloader? Which stock rom version should I choose?
Very much appreciated if you have gone so far in this reading and have some piece of advice. Also excuse terrible English.
Hi !
I see plenty of firmwares on samsung website so pick one and see how it works , it doesn`t matter the region , you won`t damage anything , maybe the modifications that has been made on the device borked the network , clean stock firmware flash may resurrect it and try the one which matches the bootloader

Good luck !
Hello,
For some days I had a thread where my audio suddenly cut off or some weird noises appeared.

What I´ve seen the problem is not uncommon and it is software related. So I wanted to ask you about your experience, could you fix the problem by flashing a custom Rom?

It is different because I think it software related and I want to know if it is possible to fix it throught different Roms.
My prior thread was different I didn´t know why it happend.
No, it's exactly the same, with the exact same problem and exact same video

So what? Making multiple threads isn't going to fix it, make 1 thread and wait for an answer
Happens to me whenever my phones swaps from WiFi to LTE or vice versa. Otherwise if it is a software issue it's most likely a bootloader/modem mismatch. Have you been jumping between 6.x and 7.x Android? Because if you use a 6.x bootloader/modem with a 7.x android or the other way around, it will break vibration and other aspects of the software.

No, I stayed on android 6 never updated or downgraded but what do you mean with modem? or bootloader/modem. Maybe I should add that I rooted the phone to gain twrp and root. And vibration and other stuff works well besides this sound problem
There are 4 firmware components, the OS/ROM, the bootloader, the modem, and the carrier config. When you change the OS/ROM, you should be changing the rest to match.
If you've stayed on android 6 you should be okay, however it's not a bad idea to go to updato.com, download the most recent 6.0.1 stock firmware for your country/carrier and flash the bootloader (BL) and modem (CP) files. There's a guide on updato.com showing the step by step process, just make sure you don't do a full flash. Only the bootloader and modem.
Since the bootloader is essentially the backbone of your phone, it's always beneficial to have it up to date with your version of android (Don't use a 7.x bootloader on 6.x). Modem updates also help with your phones signal and data performance.
You should find most ROM guides say always update the bootloader and modem before installing the ROM.

And that is how you fix your problem? Update the bootloader and modem? But after the flash I can still keep twrp or do I need to do the process anew?

So thats the version with the correct AP, CP and CSC when I flash the modem and bootloader everything should be fine I hope.
Yea my problems were fixed doing this, and if you only flash BL and CP you won't lose any data or TWRP.
I can't guarantee it will fix it, but it's a good start.

I flashed it but the sound problem remains it didn't make that aggressive sound cut off and noises like in my video but the sound still cuts off
After flashing a stock android 7.0 firmware with Odin my phone boots up normally without any problems, however it doesnt detect my network.
The firmware I used was from argentina, which is not my country but uses the same 4g bands so i figured it wouldnt matter.
is there a way to fix this? or i just have to flash to my old firmware (which I totally forgot which one was it).
I would appreaciate any help, Im a novice when it comes to this stuff.
back to stock
After the root to the stock firmware, did you a factory reset?
Sometimes it will help after you put your phone back in stock firmware.

Call your provider and ask them to reprovision your device on their end. That helps often.
Please help me.
My S7 duos (G930FD) doesn't accept official stock updates or custom ROMs. If I install any of these, my phone gets stuck on "EMERGENCY CALLS ONLY" unless I return to my nandroid backup. I upgraded to Oreo and had no network at all. I searched for new networks but found none and even sometimes I could find my network, if I try to register it, I will get network not available. I also tried some custom ROMs and had the same experience. Its like I only have to remain on my official stock ROM. Any attempt to upgrade ends us frustrating as my phone will never get network. Only thing working will be WiFi. I can't use nougat custom ROMs as well as Oreo ROMs. No upgrade at all whatsoever as my phone will completely lost network. One time I upgraded to Oreo and tried to do a restore of my EFS but yet nothing positive, I even tried to patch the network with Z3X box but all attempts went in vain. Am so confused about this situation.
Please I need urgent help.
So I have lineageOS 19.1 (android 12) on my tmobile variant oneplus 9. It was a long bloody war and much sleep was lost along the way. Everything seems to work okay, kind of. Phone gets stuck in fastboot for 2/3 times every time I restart it. And I have no data or sim card even detected when it does boot. I think it all comes down to the modem.img. I assume that I just need a modem.img from a stock android 12 tmobile variant, so if anyone could supply me with one of those (I have searched and haven't found one anywhere) I would be quite thankful.
Or if you know something I don't and that's not even the problem, please let me know.
