OK, so since I have been getting terrible battery life on my Xperia Z3 Dual (around 3h SOT, not even 24h since last unplugged), and highly affected by the "Mobile Radio Active" bug on Android Lollipop (as seen on https://code.google.com/p/android/issues/detail?id=165558), I have been tempted to downgrade my Z3 Dual to KitKat to see if I can manage to get better results.
However, even though I have looked up both here on XDA and on Google, I haven't been able to find an accurate guide in order to downgrade Android versions.
I have already found apparently a good ROM to fit my needs (D6633 KitKat for Brazilian region):
http://www.stockrom.net/2014/12/baixar-stock-rom-original-de-fabrica_11.html
According to this website, using this ROM along with Flashtool and Fastboot will suffice.
Can anyone confirm this info? I know the tutorial (http://www.stockrom.net/2013/03/tutorial-como-instalar-uma-rom-original.html) is not in English, but it does seem accurate according to the comments...
Therefore, I kindly ask anyone who has already downgraded to confirm these procedures. Will I need anything else? Will I lose anything on my phone?
Thanks a lot.

Interesting, I own Z3 Dual and run Lollipop ROM with no significant issues. To downgrade just flash appropriate ROM with Flashtool. Once you go back to KitKat do nandroid backup, wipe your phone and do clean install of Lollipop again. That way you can go back and forth to test both ROMs. Perhaps your issue stems from upgrade from KitKat to Lollipop instead of full wipe and clean install...

I (finally) got the OTA update notification to switch to Lollipop from 4.4.4 KitKat. I believe there is a 5.0.2 version out there as well, but haven't gotten this alternative yet?
Would I gain anything from this update except aesthetics upgrades? What can I expect from battery life (a big concern)? Is the update reversable (i.e. can I go back to KitKat)? What are the pros and cons of Lollipop?

Hi, I would do the update if I were you. I'm on Cataclysm and the battery life is great. Version 5.0.2 is only for Nexus 7 and 10 AFAIK.
You can always revert back with wugfresh's toolkit.
For a not-so-detailed listing of the new features have a look here, or search for youtube presentations of LP.
All of my Android devices (N5, 2014 Moto X, 2013 N7) are staying on KitKat. Aside from all the bugs that people are complaining about with Lollipop, I just don't like the look of it. Google went way too far in their attempt to create mainstream appeal, and made it way too pretty and colorful for my tastes. I think KitKat is still the best version of Android to date. All my devices are stock rooted + Xposed, and I will likely never update them. The only way I'll use Lollipop is when I buy a new device that ships with it.

I got the OTA at around the same time as you did so i quickly updated, i haven't experienced any bugs on 5.0.1 yet (i don't think 5.0.2 will be coming to the nexus 5) but i must say lollipop feels soo much smoother
I'm also staying on kitkat on all my devices.
In case I get tempted or "accidentally" update, won't my current twrp nandroid backup allow me to return to kitkat or will it be more complicated?
If I wanna stick to KitKat, how do I remove the constant notification in the drop-down bar? Also, how does Lollipop deal with managing contacts, merging duplicates, contact list layout, etc (not too happy with that in 4.4.4)?
I foudn my battery life got decently better on kitkat

You can always flash factory image and then flash your backup, there's no problem.
Hey guys, I just saw that 5.1.1 has been available for my N915G for some time now. I would like to ask how people are feeling about it in terms of performance? I was on 5.0.1 awhile back and it was so laggy and slow that I eventually downgraded to 4.4.4 (at times, I wouldn't even be able to answer calls because the phone would ring but the phone was so laggy that the screen wouldn't turn on until after they hung up).
I'm very happy with the performance of 4.4.4 now but I do like the features in Lollipop so I just wanted to ask if it's safe to jump back in? I heard that it's not possible to downgrade after flashing 5.1.1 so I need to be sure before taking the dive. Thanks a lot in advance!

Phone works really smooth, no lag at all! Even multitask works really well

Thanks for the reply. Although I am always a little cautious when I hear people say there's no lag at all. I have never had a non-stock Android phone that was lag free (well, with the exception of my old Z1 Compact maybe). Even on 4.4.4 where the performance is far better than on 5.0.1, there is noticeable but tolerable lag at times. But still, I'm glad to hear you're having a good experience on it!

Also to add, battery life is 4x now!
how did you update 5.1.1, I'm on 5.0.1 and OTA doesn't show any update available?

It depends on what version of the Note Edge you're on. Mine is SM-N915G (yours could be 9150, 915F, 915FY etc.) and sammobile.com listed 5.1.1 as being available. Then you need to flash it through odin. There are tons of guides around for that if you do find a compatible firmware for you.
I have 915G. Can you please provide any updated working guide /links?

Well I haven't done it yet myself but I'm pretty sure it works the same way as with previous firmwares. There are heaps of guides here and elsewhere that describe the steps to using Odin such as this one. And get the firmware from here.
Question for the more knowledgeable people: Does the baseband version on my current firmware have to match with the one I'm trying to flash from Sammobile?

Shouldn't matter, it's the "G" that's important.
There is both a Telstra rom and a generic rom of 5.1.1 so you should be good to go.
If you want to get root access you will need to flash a 5.1.1 root enabled kernel however...
Hi guys.. I bought the new xperia z3 dual d6633 phone. It came with lollipop 23.4.A.0.546. I already made the a pre-rooted ftf build using PRFcreator on the latest lollipop build available. But when I was about to root, I came to realize that I would need a working root and Dual-Recovery manager installed on my phone to flash the pre-rooted latest build. I searched across the internet but its quite old and confusing. Here I believe as our fantastic experts on xda-forum, will know everything for everything got to do with the Android world. Please buddies help me out. I would be humble thankful to you. :fingers-crossed::victory::victory:

Google is your friend. You have to downgrade to kitkat, use giefroot tool to root, then install recovery and finally flash your PRF.

It was much to have my post left only seen by the visitors but not left with a useless junk comment like yours. You came like a tornado, left a piece of junk and then simply flew past like lightning struck the tree and people never knew what burnt the tree. Neither you pinpointed where I will get this tool and secondly you didnt even bother to give the exact Kitkat build number to flash before even attempting to root using Giefroot tool. Anyways. I did find out myseld the giefroot tool and for you pathetic knowledge, it is stated that the tool doesnt even bother to work on the kitkat version i downloaded and flashed on my Z3 Dual D6633 phone. It's always giving me error that ADB server is out of date and killing. Will you bother yourself explaining to a noon like me to figure out what to do next when stuck in the middle of such a mess. Any further detailed elaboration would be highly appreciated by me. Thanks.
here is the screen shot for the error.:crying:
@noob_coder
Look, its not my fault you cant read. The first post in the giefroot thread says to use firmware from October 2014, and as for my pathetic knowledge, ill take it elsewhere and let you figure out what you have done. A bit of advice though..... Read read read before you do anything.

Try downgrading to 5.0.2 and then root using kingroot and then install recovery. Then flash a prerooted rom or stock based rom.:good:
So lately I have been on and off between lollipop and marshmallow. However the mobile radio active bug has been getting out of control for a while. I live in China. OPO bought in Germany though. So I don't know if that makes a difference. The general theme I noticed is that standby time and SOT was best on KitKat. Can I just flash a KitKat Rom in order to downgrade? Or is the other thread in general on how to go back to 100%stock the only way?

1) You posted in wrong section of this board
2) You did not used search option for your query
3) You did not visited any of the sticky threads
4) Follow guide 8 of this thread to revert to stock kitkat : forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471
Read it properly and proceed.
This is not a 'best ROM' thread, simply a request for assistance.
My friend experienced abysmal battery life when her phone updated to the (stock) Lollipop ROM. I rooted it, installed Multirom and flashed a Kit Kat ROM for her, which means she could actually use her phone for more than 7hrs without it dying.
Now Marshmallow is out I want to give her a secondary ROM to test out. But I don't see her that often and I want a ROM that offers auto-updates so that so long as the dev releases delta updates then she'll get them. This is to assuage my concern regarding her going for the next year with no security updates.
1. Can anyone recommend a MM ROM that has this feature?
2. Is there any reason why Multirom would interfere with an update system like this?
Thanks.

Why would you install MM on a device that belongs to someone else?
a hammerhead wrote this.
I'm struggling to understand the question. If your friend isn't technically able, then surely the simple course is to wipe and install MM, leave it stock, and she'll get all the Android OTA updates as they arrive. Is this not exactly what you want? Why over-complicate her life with multiple ROMs?
Just asking...
