You should mention that downloading and installing of g-apps is not necessary in most cases. F-Droid is a really good alternative market. And if you still need apps not available on f-droid you may use yalp or aurora...
And if you depend on some google services microG may be a good solution for you, especially in the flavour of NanoDroid.

Hi,

For an average user, GApps is recommended so the device can be fully functional with access to the main Google Play market and to avoid "issues". For example, push notifications to work in Pie need Google Services etc.

I agree, F-Droid is a good alternative market but some apps may missing from there. About microG and NanoDroid I am not a fun.
However, I want to mention the alternatives options but unfortunately I have hit the maximum words I can contain to OP. I am thinking to split OP to two posts but I am not sure yet, I will see how I will do it.

Btw at reserved posts, will be included Battery Save tips and more.

Thanks for your suggestions.

In your lists of variants (bootloader etc.), I don't see SM-S975L. Has this variant been dropped?

Sorry. In my school they only taught Russian, but there are translators. Stupid to ask but have to. I have s4 9505 variable modem and bootloder from I9505XXUHOJ2 to XXUHQK1. Now I don't have LTE only EDGE. I know for you builders to laugh and for me a riddle so I am asking builders for a tip that I would come back to LTE.
Wi-fi enabled is ok, just outside edge

Welcome to XDA and this forum. Here on XDA we use the English language. But a lot (most?) of us aren't native English speakers. And automated translations sometimes aren't clear and correct. So it is good practice to try to translate your text to English and doublecheck the translation yourself. And to add your original text for native speakers, too, if in doubt...

Make sure you have the same Firmware version as your Modem & Bootloader version. If you have flashed QK1 Modem and Bootloader then you need to flash QK1 Firmware.

 

[kurkawodna]

As I mentioned, English is a translator. QK1 Firmware need to be installed after changing the modem and bootloder? This is for Croatia and Austria. Is Polish in your settings? Clean and upload v12.1? I guess the questions are at child level but I am asking for help anyway. After all upload v12.1?

Doesn't matter if you flash Firmware after or before. Your Modem and Bootloader will stay as it is, unless you flash again different Modem & Bootloader.

Country doesn't matter, you will find your language in settings.

What do you mean "clean and upload v12.1"?

Don't worry, ask anything you want. I will try to help.

Let it not be, without petroleum jelly, nice that a professional wants to help and not to instruct. S4 small, grateful phone, not the pingpong rackets. I started with cyanegen through other mods and worked out after changing the boot. I understand that after this change you need to upload the official I9505XXUHQK1 and then flash on v12.1? I just downloaded I9505XXUHQK1 T-Mobile.

I don't really understand what you wanna do.
You can find everything in my guides and collection in OP and post #2.
What is v12.1 you are talking about? Optimized LineageOS v12.1? You wanna flash that ROM or you want to flash Stock ROM?
What ROM do you use right now and what you wanna do?

I was on LineageOS16.0 on XXUHOJ2 versions up to 11 I had no problem with LTE. With version 12 there was a suggestion to change the boot and modem to XXUHQK1. I did it and I don't have LTE but only EDGE. I ask what I did wrong because obviously the fault was on my side? I want to have this soft but with LTE.

Do you mean S4 mini when you speak about small S4? This device isn't i9505 aka jfltexx.

Perhaps you should look at https://forum.xda-developers.com/galaxy-s4-mini/orig-development/rom-lineageos-16-0-s4-mini-t3833063 or it parent forum.

No. S4 i9505 LTE. Writing small I meant the difference in the size of current phones.
