i9505 Set Warranty Bit: Kernel

[ReevPL]

Welcome guys,

I have Galaxy S4 and I wanted to install Custom ROM. Unfortunately when I installed TWRP (the newest build), my phone displays "Set warranty bit: kernel" and then it boots into Recovery Mode (twrp works fine), but stock ROM doesn't boot. I don't know how to deal with it. Will custom ROM install fix that problem? I don't want to brick it.

I have access to download mode, TWRP (as I said before, when I turn phone on, it boots into TWRP instantly), but unfortunately ODIN doesn't recognize phone at all.

Please help :crying:

Does the computer recognize the phone?

After installing, did you select the option to allow changes to the internal memory?

Tried different USB cables and USB ports?

If you get the phone recognized by Odin, I suggest flashing a stock ROM via Odin and checking the phone to ensure complete functionality. Once you know the phone is working on a stock ROM, maybe start with an older version of TWRP such as 2.87.

Flashing a custom recovery should not prevent the phone from booting a stock ROM.

I'm such an idiot. When knox is tripped you cant run stock ROM, so basically I just installed LineageOS and it works hah

Tripping knox does not prevent a phone from running a stock ROM.

So it's strange though. I couldnt boot stock ROM and the only thing I had to do was install a custom one. Anyway, thanks for the answer

I've flashed TWRP to a number of Samsung phones which cause Knox to trip and the warranty bit to change from 0x0 to 0x1. Despite this, I have been able to flash and use stock ROMs with a tripped Knox indicator.

Maybe the phone needed a factory reset using the stock recovery after being flashed with Odin?

Aaaand here we got the problem. I tried to install twrp many times and unfortunately the stock one stopped running (dont ask, i dont know how it happened). Despite this everything worked but I wanted to install custom ROM and then that problem happened. It was just the lack (??) of stock ROM or knox blocked the availability to boot it.

Oh, completely forgot. I installed TWRP by LineageOS' tutorial on their page

It all worked out in the end which is the important part.

Thanks for sharing your solution.
