[Q] Upgrade while maintaining root - Xperia Z3 Q&A, Help & Troubleshooting

I currently have a xperia z3 running 4.4.4 rooted. I would like to upgrade to 5.0.2 or even try out other roms. My problem is I don't know the do's and dont's when messing with android (previous iPhone user).
I know that the DRM Keys are a big deal and I have those backed up. I just want to know what is safe and how I can ensure that I won't end up bricking my phone.
If anyone could point me in the right direction it would be greatly appreciated, thanks!

If you want to upgrade, you have to flash pre-rooted 5.0.2. Its the best and easiest way for you. Just flash it and you are done. Check the guides in general section.

[Q] Noob Rooting Motorola Cliq - NEED HELP

As the title states, I am a super noob when it comes to rooting, and I've been trying to root my Motorola Cliq. I've been nearly bricked, so I've decided I'd ask around instead of trying to figure it out myself. Before I ask my questions, here's the facts:
SYSTEM VERSION: Blur_Version.1.3.20.MB200.Orange.en.FR
(The thing is, I live in and purchased the phone from T-Mobile in USA. I think I may have loaded a ROM or something that was for the FR version of the phone
It runs too slow, and main reason for rooting is to increase performance speed and whatever other perks come with rooting are certainly welcome.
Questions:
What is the easiest way to root my phone?
How can I check whether or not my phone was successfully rooted?
After rooting, what is the best, most functional, and most stable ROM I can apply to my phone, without losing too many features?
Thanks in advance, I really appreciate it!

Help with my LT28AT

I am looking to upgrade my Ion LT28AT to the CM10 for locked bootloaders and am kind of leery since I only recently rooted it and don't really need a brick. I am open to any advice and of course help with this. I did check out the thread that lists the downloads themselves but I don't know how to go about flashing them to my phone.

[Q] FTF File needed!

(It's my first thread here so forgive me for any errors or unspoken rules that I have broken )
Hello XDA! Today I have come seeking help.
I own a D2303 M2 with a locked bootloader without root sitting on Kk 4.4.2,and I want to downgrade to 4.3 so I can hopefully use towelroot to root.
Here comes the main problem/question:
I'm running the on the UK exclusive 'EE' network. If I flash a stock ROM with the wrong carrier,will I be kicked off of my carrier network? I can't seem to find a 4.3 ROM that begins with the build number 18.3.C and EE to stay on the safe side. If anyone could upload or point me in the general direction of one,that would be great!
Thanks in advance, (hopefully)
Just another JB noob

[Completed] [Q] Having trouble understanding steps to rooting sony z ultra gpe

Ok im having trouble understanding this. Im new and ive read for countless hours but it seems as though i have to install a custom firmware?? Not sure what a kernel is so im leaning against that. I have a z ultra googleplay edition running 5.1 lollipop. Should I downgrade to kitkat 4.4? Is that even possible? Ive heard by unlocking bootloader you lose camera function and screen resolution which I defenitely dont want to do. Any help would be grear. It seems as though even the people that own stores that told me they can do ut are giving me the run around. If anyone knows someone that has done this before and put me in contact it would greatly be appreciated as well.

Deciding on buying a Droid Mini

Hi everybody,
I'm planning to buy a use Droid Mini but was wondering if it is actually worth it, considering the posts here about the effort involved in rooting/unlocking the bootloader/custom rom etc.
I'd be much grateful if someone could advice on the below
- If I were to get something on a version less than 4.4.4, then I'm assuming I can root/unlock bootloader. Can install a 5.x based ROM?
- Is the alternate way to achieve root, apart from SunShine? http://forum.xda-developers.com/showthread.php?p=45598648
- If the above is done, does it stay that way even if we upgrade to a 5.x ROM (assuming it is possible)?
Thanks much
