[Q] Downgrade 4.4.2 to 4.3 Galaxy S4?

TheCatsDad said:

Can anyone help me please? I've never had an problems upgrading or downgrading my old Galaxy S2. I got a Galaxy S4 last year and it was running perfectly.

A couple of days ago, I was backing my phone up through Kies and it said an update was available. I didn't use Kies to update my phone though as I wanted to back up my data first. I disconnected from the laptop and did an OTA upgrade.

Huge mistake!

Since the upgrade, my phone keeps locking up/freezing. The gallery app freezes constantly. If I try to attach a photo to a Fabecook post, it freezes my phone and in all cases, the only way out is to restart my phone.

This update has left my phone worse than useless. I can't do anything on it without it freezing.

I've tried factory reset quite a few times. I've wiped cache partition a few times. I've taken the SD card out. Nothing works.

I've read that the new bootloader renders it impossible to downgrade.

If I find an official 4.3 Jellybean firmware, will I be able to revert back to Jellybean by flashing it through Odin?

Otherwise, I'm stuck with a phone that no longer works.

Does this mean I'm stuck on 4.4.2? I really want to go back to 4.3 as that was stable.

Do you know anyway to fix it please? I use my phone constantly for work. I can't use it as it is.

So it's possible to download original 4.3 firmware from Sammobile or somewhere else and flash that? I'm scared of bricking my phone.

Thank you all.

I think I've fixed the problem without having to downgrade.

First of all I formatted the SD card, I switched my phone off, removed the SD card and restarted it. Then I did a couple of factory resets, turned the phone back off and reinserted the SD card.

I think with it having a complete wipe of everything, it fixed the problems with the phone lagging and freezing constantly.

So far, so good.
