Sony Z5 - rooting/unlocking bootloader/back up of drm keys - Xperia Z5 Q&A, Help & Troubleshooting

Hi XDAers
Can anybody help me out - I have always rooted my phones and after purchasing my Sony Z5 last year I thought by now there would be a relatively easy way of rooting. Apparently I can unlock my bootloader to go to the next step of rooting, however I would lose my drm keys... of which I cannot backup without root!!! Rooting is still blocked because of the locked bootloader. I have recently upgraded to the Android 7 firmware - ugh, I can't stand it and it really messed my phone up - so I want root even more. I'm not hugely techy and I don't feel brave enough to go through a lot of complex downloadin and flashing of different programs etc - but I would really appreciate some advice.
The amount of bloatware on the phone is horrendous and I really miss my Titanium Backup..... is the Sony Z5 a lost cause and is it time for a new phone?? Don't think I would ever go back to a Sony.
Anyway, if anyone has some advice for me I would be really grateful.
Thanks
Jackie

[Q] Please help me root my xperia x10 mini pro 2.1 update 1

Hey all, this is a great forum and ive got my phone locked, now ive paid for it to be unlocked and i think its only fair that i can be able to remove the software that comes with the phone from the phone carrier which i dont need: like uno trial, guitar hero trial etc...
So ive heard that i need to root my phone but i am totally unexperient at this as ive never done it before and never had an android phone before so please could someone give me a full step by step guide of what i need to do to root my xperia x10 mini pro android 2.1 update 1? its a great deal for me as not only it should help me remove useless apps that keep installing themselves once i restart the phone but it also helps me install apps on the SD card rather than on the limited 128mb phone internal memory.
Thanks very much in advance!

[Q] ZTE (Telstra) T28 rooting

Hi, folks.
I do apologise if this is the wrong place for this - so many forums to choose from!
Earlier today I bought a ZTE (Telstra) T28 phone to replace a damaged Samsung Galaxy Ace, as they have pretty much the same features.
What I forgot, though, is that I had rooted the Ace, and installed a custom ROM. So despite the same features, I'm a bit uncomfortable with the T28.
I did notice that its features are similar to the ZTE Blade. This is probably a long shot, but does anyone have any information on whether I may be able to root it using the same method and files? Or at least if it is possibly to ATTEMPT the rooting method, with a means to identify if it isn't going to work/back out without waiting for the phone to be bricked?
I did install Ask Mr. Pigfish and it suggested I was using a Gen2 Blade, but I suspect that it was simply identifying that it was using the same Android version. (Kernel? Am I using the term right?)
If it helps, when using the usual Android "Check for updates" option in the menu, it tells me I can copy an update image to the SD card, and can update from that menu.
I'm quite happy with the phone; I'm primarily wanting to root and update not for update's sake, but to remove the pre-installed apps. The device is exclusive to the Australian Telstra provider, but I am not a Telstra customer. I am using a different provider that resells the network, so the installed Telstra apps do not work for me and take up a lot of the device's tiny space.
Cheers and thanks in advance for what I'm sure will be a lot of useful info!
Hi and sorry for the grave digging but I really need some info about rooting the T28. I'm completely new to rooting and would love to find a one-click-root or something but no such luck. Has anyone rooted this phone successfully? I'm stuck with this one so hoping for a positive answer

backup of drm-keys on Z5 necessary, when switching to lineage OS?

Hi there,
after owning my z5 for nearly 2 years now, I really want to get back to cyanogen / lineage os. I loved CM on my old Galaxy S4!
I read in several posts and forums that, when unlocking my bootloader without backing up the drm keys of my z5 device, the quality of the photos / camera will get worse, ' cause the sony algorithm for image processing won't work anymore without those keys.
But....
When I open up the bootloader (wihtout prior downgrade to Adroid 5 for backing up my drm keys), in order to get root access, install a custom recovery like twrp and flash lineage os, wouldn't be those drm-keys be useless either way? Or do I have a misunderstanding in anyway? Because when flashing lineage OS , I suppose the sony algorithms for picture enhancement won't be used anyway, because of the different OS (lineage instead of "Sony-Android") ?
Second question:
Does anyone have experience with a rooted xperia z5, without drm-keys (no prior backup) ? Is the picture quality really so much worse? Especially when using cyanogenmod or lineage OS or any other aosp?
thx for your input
Q1.Downgrade android 6 with flashtool. No need BL unlock. Read my thread. Download android 6 ftf and follow step 1 to 14. Use backupTA v2, works with android 6 and no need root access. Then unlock bootloader.
Q2.All custom roms has drm fix solution, so no need drm keys anymore. In my thread there are also patched kernels which means no need drm, everything works like stock.
You have z5 about 2 years, so no need to backup keys. Your warranty is void now. Unlock bootloader, use custom roms or stock with ROOT access and many features.. Try all stock based roms like existens, rsx. They have XZ UI and many more..
Have fun with your new Z5 experience.
My thread on General. Nougat FTF, it has all instructions about installation. @Sy36
Thank you for hints and advices. But I also want to have root-access to my smartphone, because i want to use adblock and a firewall and other stuff, for which I definately will need root access. So I will have to open the bootloader of my device.

Rooting a Xperia 6616

There aren't many new topics on this model so here we go,
My z3 stock came with 5.0.1 and as far as i know never (the 6616) had the 4.4 as an option. SO downgrading didn't work, so i'm stuck trying to root this with 5.0.1 and after two days of browsing this site there really doesn't seem to be a way to do so. Eventually i said $%#* it and rooted it using kingroot but after rooting it, root checker passed the root but would not give proper access when installing root apps such as busybox and the ta backup tool.
So i didn't realize that the keys ive been trying to save are useless anyways if i update android and the main reason for me going through this is i really don't like 5.0.1. Only thing i haven't really looked into doing is seeing if kingroot will let me unlock the bootloader then trying to flash an update. SO has anyone successfully updated a 6616 z3 (to 6) who didn't start off with 4.4?

Verizon Galaxy S7 Edge: Removing bloatware after 1-Clk-Root

Just picked up a carrier unlocked Verizon Galaxy S7 Edge model SM-G935V.
Now that I finally have a model which seems like it should be relatively easy to root, I would prefer to learn to do it using a PC ie flashing ROM, but I have no PC access right now.
My main question is:
After rooting my phone using a 1-click root method, will it be relatively easy for me to un-install ALL bloatware & eventually end up with a phone that's running just as efficiently as it would if I had picked out and flashed a good stripped down ROM using a PC instead of some 1-click method?
I'm also considering purchase and use of Super-sume Pro (if the job is done with Kingroot).
Any advice AT ALL regarding what I hope to do would be greatly appreciated... and jic it helps here s a little of my background:
I have NO successful experiences using TWRP or the like w other phones.. although I believe I came close!!... my last few phone picks turned out to be models which were pretty much impossible to root (locked bootloader was the common culprit best I could understand).... Otherwise I think I'd have been able to do at least 1 previous model the flash-rom way.
I DO have A lot of general experience w PCs and have successfully rooted a few phones using 1 click Android software such as Kingroot, but at that time I did not fully understand or hope to remove bloatware to cool battery or otherwise dial in best performance.
It's been at least 3 years since I last performed a 1 click root on any phone.
Thanks in advance for any advice or assistance... I really appreciate everyone & everything at XDA.
