Hello everyone,
I was thinking about installing Lineage OS on my Samsung Galaxy S4 GT-I9515 (Value Edition) currently running Stock Android Version 5.0.1 without root.

Is the version of Lineage OS and TWRP I found at https://forum.xda-developers.com/gal...i9515-t3534552 appropriate for that purpose?

Now, my confusion arises from the fact that different guides seem to give incomplete or even contradictory instructions on how to approach that. As a first step, I need to install a custom recovery, such as TWRP:
  • Does this require my device to be rooted?
  • Some guides apparently require my bootloader to be unlocked; Is this necessary? If so, how do I do that?
  • Other guides suggest that I use Odin. Is this the correct approach? Does my bootloader need to be unlocked for that method? Is a root required?
  • Anything else I should pay attention to?

Thank you very much in advance

You need to find a guide for your phone
Different phones have different processes

For example Motorola phones require you to unlock the bootloader where as Samsung phones Iv worked with you don't

Some devices you have to root first before you can flash twrp while others you flash twrp first then root


For most Samsung phones around the age of yours you can root using CF-Auto-Root
This is done via odin and all you do is put your phone in download mode load the img file into odin & flash
The same is true for flashing twrp

Here are the files for your phone
CF-Auto-Root
TWRP

Flash each image in odin

What do you mean by brick?

Does the twrp boot?
You must boot twrp straight after it's flashed - if you don't and your phone starts to boot you need to reflash it (once booted to twrp for the first time the recovery will stick)

Also if you swipe to allow modifications in twrp your rom may not boot unless you disable dm-verity - this can be done with a root zip eg CF-Auto-Root or magisk

Remember you may need to do other steps like enabling adb debugging & oem unlock before using CF-Auto-Root
You also may need to root before flashing twrp

That is the twrp for the S4 GT-I9515 - if you have a different variant it will not work

If you have a different model of S4 check the twrp website to see if there is an official version

I don't own your device - I'm sure there's guides that will you step by step process if you Google

Flashing a recovery should not brick your device - you are just replacing stock recovery with a custom one - your phone should boot regardless but anyway

I assume you have enabled USB debugging - enabled oem unlock (if it's on your device) and flashed CF-Auto-Root first

I also assume you are flashing the tar image in the AP section of odin (you may need to Unzip to get filename.tar)

If you have done all the above search Google for a step by step guide for your device

Since I don't own this device I can't offer anymore support than that

Long as it's the correct firmware for the device no reason why it wouldn't flash
Check download mode & make sure that the model number matches the firmware

If the firmware is also failing to flash I would guess there is a problem with your setup rather than the files (assuming the files are correct)
