[D5833] Lost Root after update - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hello,
I have a z3C running lollipop (updated from PC Companion), which had KK fully rooted. After the update I've lost root and seems I canĀ“t get it back.
Is there a way to fix this?
Thanks!

you can't update via PC companion and retain root. you'll need to downgrade back to kit kat, root again, and then upgrade to lollipop by flashing a pre-rooted rom.

4.2.2 OTA to 4.3 ? Root preservation ?

Hi all,
I have a few questions that burn me. Just received the OTA notification that .569 is available (304.4 MB)
I am running .67 with stock recovery, root and phone encryption. Will those be preserved if i OTA update ?

AFAIK root is lost and recovery is rewritten. I don't use phone encryption but I guess it is ok (or it would be stupid of Sony).
My experience has always been that OTA updates break root, and most of the time you wont be able to get it back until there is an exploit for the new firmware
4.3 OTA update will take away root and you will be unable to root under 4.3 directly.
You have to use the root methods shown as below(root under 4.2-flash another recovery-flash pre-root 4.3).

OTA left my root as it is. Check my post, how I did it:

This was the first OTA that broke my root, even with supersu in survival mode.
I updated ota from 4.2 to 4.3 and kept root.

OTA update after rooting

So.. I was on 14.2.A.1.136 (4.3) stock firmware.. I wanted to root and I had to downgrade to 4.2.2 then root then flashing 14.2.A.0.290 (4.3) firmware.. Thanks to @shem2409 and @[NUT] for this method.
Anyway.. After rooting and flashing and all of that.. I received an OTA update for the stock 14.2.A.1.136 firmware.. And I was really surprised because what I know is that you lose the OTA updates and pc companion updates capabilities after you root your phone.
So my Question is.. If I updated the firmware OTA will I lose thr root? I can't afford to root it again for at least 3 weeks because my laptop is on the maintenance right now ..and I need the root privileges.

Hi
Did the same thing for my phone....however I did not update back to 4.3 via ota but instead downloaded the pre-rooted firmware version for 14.2.A.1.136 pointed out bh someone to me on xda. I'd suggest you do the same as I havent lost root access after finishing this.

is it the same firmware ?? I mean .. is there any differences between the pre-rooted version and the original ?
and I read about that there is a chance of hard brick the phone after doing this .. did you face any similar problem ?
No... I had no issues.... Yeah the same firm ware...

Stock recovery lost!

Hi all, as the title I lost my Xperia Z1 stock recovery!
I had 4.4 with 14.3.A.0.757 firmware rooted and dualrecovery, and I updated to 5.0.1 Lollipop with PcCompanion. Then my Z1 became pretty slow so I wanted to flash this ROM http://forum.xda-developers.com/xperia-z1/development/5-0-rockz1lv1-1-deodex-advanced-mods-t3090064 on my phone, but I recognized I had not any recovery installed! So i flashed the 14.5.A.0.242 Lollipop firmware thinking I'll get back a recovery, but still don't!
How can I fix this?
Thanks

From taking what you have wrote, when you were on 4.4 kitkat you rooted your phone and put dual recovery on, your mistake was to upgrade to lollipop using the PC companion instead of finding a pre-rooted lolliop on these forums, hence the reason you lost recovery, the only way to get it back would be to go back to kit kat and then root your phone put dual recovery on flash the firmware you want from recovery.

Can I update my rooted 5.0.2 to 5.1.1 via official update without loosing root?

So I just rooted my z3c using the guide from above and now have a lollipop 5.0.2.
Is there any way to get 5.1.1. without loosing the root?

If you have received an OTA dont install it. You will lose root. As suggested, download a custom ROM and install. Its more fun like that!

Use a prerooted fw and install via flashtool. A tut how to make a prerooted fw is also in the forum.
