Default [Q] downgrade questions

Hi

Noob here

If someone could shine a light here it would be appreciated.

I have an xperia z1 that I was happy with on jelly bean. The first buggy kit kat upgrade was not pushed to me by my Canadian carrier probably because of the issues. The supposed fixed kit kat did get pushed to my phone ota and I took it.

Short story it sucks. Still lots of bugs

I want to go back to the last jelly bean version 4.3

I read somewhere that I should not flash 4.3 but instead flash the previous version then upgrade to 4.3?

Do I need root to flash a compatible ftf to my phone?

If I do flash to an earlier version of jelly bean 4.2.2 I think? When I upgrade, will it skip the 4.3 and push me to kit kat again?

Thanks in advance

No root needed

Just find a FTF that you want that is compatable with your phone in the Mega Collection thread in the general section. Then flash it with flashtool

All instructions, files and downloads are in that thread

If you are unsure, then read this.
If you are still unsure, watch this.

If you flash 4.2.2, Yes, a notification will pup up of the latest version, but you don't have to flash the 4.2.2. Same when you will downgrade to 4.3, you will have the notification so you will have to disable that by hiding notification in Update Center App or disable that app permanently.

Thanks for the insight

I flashed a generic 290 jelly bean ftf to my phone
Though an update notification came up saying there is a 51.2mb update 14.2.a.1.136?
I don't remember getting this when I was on 290 jelly bean. the next update was the 2 kit kat versions

.136 is a newer Android 4.3 version. Then it goes to .681 and then the newest .757.

The easiest is to just flash .757 with Flashtool:

I was on 757 but too many bugs on my phone
battery drain, weird crackling sound from speakers with ringtones and notifications, practically inaudible call volume person can hear me but I can barely hear them even with all volume settings maxed out

there are probably more but just those above made me flash to a jelly bean firmware
