Root Missing OEM Unlock on Samsung Galaxy S4 i9505

[Hoegali]

Hi,

I am intending to install TWRP on my Samsung Galaxy S4 i9505 with the aim of installing a custom ROM but am not seeing the 'OEM Unlock' option under 'Developer Options'

I have looked at the below guides for resolving this issue but neither appear to be suitable for the S4.

https://www.xda-developers.com/fix-m...galaxy-note-8/
https://www.thecustomdroid.com/fix-missing-oem-unlock-toggle-samsung-galaxy-devices/

Does anybody know how to resolve this?

Thanks

i'm not sure the s4 had that feature back then.

here is a guide

once rooted however, i would recommend that you switch recoveries to twrp:

I see both these guides use Odin. Are there any guides which do not use Odin? I am a linux user and this would mean running Windows on a virtual machine.

I used ADP the last time I did this.

All Galaxy S4 models... except for AT&T and Verizon, have unlocked bootloaders.

I also use linux and to flash twrp on my old Note 4 I used Jodin3. It's Odin for linux and mac.

I uploaded it to my github account for you to download if you need it. You can also google it if you prefer to get it from it's official source.

Jodin3 zip download...

It's written in java to make it cross-platform. Here's the source code...
