Multi-Window Marshmallow - Xperia Z4 Tablet Q&A, Help & Troubleshooting

Im wondering if its possible to enable multi-window on this tablet now that marshmallow has released. I know its most likely possible on unlocked bootloader with root but i was wondering if the same could be possible for locked bootloader?
Here's a link if it helps:

No, build.prop edits need root or a custom recovery from which you can edit build.prop on the system partition:

I thought so damn although I did notice a recovery boot file in the system folder no idea if there's an actual recovery but I don't think I can access it anyway. If only sony provided us with a stock recovery like other OEMs. Seeing this feature on the Z4T I'm sure will be great. I thought it might have been possible to pull the build.prop without recovery using adb but I guess not. If only there was root on locked BL...?

Yes, if only. Maybe this fresh MM ROM has some vulnerability that can be exploited to gain root. But knowing Sony’s extensive, custom countermeasures, I think chances are very slim.
Just unlock your bootloader and fully enjoy this tablet

Haha lol I could do that but I'm worried about warranty cus I've been having WiFi issues that come and go I plan to unlock my BL after 2 years when warranty runs out so next year.

I'm surprised

I'm surprised this device attracts so few developers. Most devices have several custom roms and kernels to choose between.
I love the device. I had some tough weeks to get use to the size but now I can't imagine having another phone.
It's perfect. I can play with it for hours.
I will send it to some of the core devs in my team when I'm done with it so we'll get official SlimRoms on it.
Can u root KitKat? I am on 4.3 and waiting for someone root 4.4. And I love this phone, too.

Odd thread choice for this post.
The answer is to read, read some more, then think about what questions you still have and search for them and read those results.

After owning this phone for almost a month as my daily driver, I can see why this phone might not be so popular.
Sony does not seem to do as much advertising as Samsung (at least that I can see), and for quite a while this phone was just too expensive. Add to that the fact that this phone for most people is just north of being too big (I came to it after owning the Galaxy note so I am ok with the size), and if you own one of these, you want to use it a lot and even with the stamina mode turned on battery life can be a little short if you turn it on to play with it every 5 min or so.... lol.
On the other hand my S4 build quality feels worse and worse after owning this beautiful thing.
One final thing I can think of is that the stock ROM (at lease 4.3 which I am still using) is not very bloated and really quite nice. I don't feel the need to try to load a AOSP rom as much. Every time I pick-up a touchwiz device I just want to throw up a little.

KitKat has already been rooted for quite some time! I am using 4.4.2 KitKat and am rooted.
Refer to Jackie's root guide. You will have to download the 4.4.2 FTF rom as well as Jackie's custom kernal in order to root.
Have you unlocked your Xperia Z Ultra bootloader? In order to root you must have your bootloader unlocked. It is very quick and easy to unlock.
Here is the link with instructions on how to root KitKat.
Special thanks goes to Jackie for making this possible so fast.

Before telling some one to unlock their bootloader to gain root PLEASE explain to then the consequences of that action:
If you unlock the bootloader before backinf up the TA partition you will lose your DRM keys and warranty. You will also lose the ablity to use some apps that rely on those DRK keys.
If you want to keep these (or have the ability to restore them) you have to downgrade to 4.2 (build ending with .532) and use an exploit to gain root

I haven't unlocked bootloader my ZU yet. And I have backup my TA already. But I dont want to UB my ZU because I want to use my TrackID app. So maybe i should wait until someone can root ZU with non-UB one.

Thanks for ur hint, man. After read some thread, I think I can use this way to root my ZU with KitKat: I am on. 136 rooted and LB, I will download KitKat zip of fnf and install it through dual recovery of [nut]. Am I right? Looking forward to your reply.

[Q] Custom ROM & security

Since large part of us might get their Z2s this week (hopefully including me :silly, I'd like to know what options we have to make our Xperias secure with soon-to-arrive custom ROMs.
From what I managed to find, the most convenient option (at least theoretically) would be to:
- unlock bootloader
- flash custom recovery
- flash custom ROM
- reflash stock recovery to prevent lockscreen bypass and adb access in general
- relock bootloader to prevent flashing custom recovery and regaining adb by potential attacker.
- then if needed, reflash recovery online if rooted, reflash new/updated ROM, reflash stock recovery back
Now, I've read that Xperia Z2 (other Zs probably as well) will softbrick with locked botloader and custom ROM/kernel, rendering this method useless. Am I right?
If yes, what other options do we have?
all i know for sure is its more complicated than samsung models n im gonna wait till there a way to root it without messing with the bootloader
-Unlock bootloader
-Flash kernel of the ROM you want (DooMKernel for stock based)
-Boot into the recovery that's baked into the kernel
-Flash the ROM you want
All AOSP ROM's require fastbooting the kernel from the zip (unless stated).

So there is no way to block access to recovery after flashing custom ROM?
Also sorry for probably dumb question (I'm new to Xperias): do you maybe know if current recoveries baked into CM support encryption? I know there is no CM for Z2 yet, I'm asking about current Z series phones.

Well... On newer Xperia's (2012+) you can flash a recovery to the TArecovery partition, so you could remove it I suppose... But if the kernel you are using has a custom recovery baked in (they usually do on Xperia) then you could flash back the stock kernel, if you don't want recovery on stock based ROM. but as far as CM is concerned, you cannot remove recovery.
And yes all CM has recovery baked into Xperia kernels. We'll have official CM support from FXP team as soon as they receive their device too. Good times ahead

You lose the DRM keys. You can't keep the DRM keys if you root as of yet, because you have to unlock bootloader to root, and you can't do TA backup without root. Vicious circle.

Flash TWRP from here
Flash the boot image from here (angler-mdb08k-boot.zip)
Flash the latest SuperSU beta from here
then you'll be good to go!
Does it require a custom kernel? I couldn't find mention of it in the link. Also, what the heck is a "boot image?" I know bootloader, recovery, and kernel. Do we now have another thing to consider?

If you just reflash the stock system image that would erase any trace of root. You wouldn't lose any data. You'll only be able to flash the root zip/kernel if you've already unlocked your bootloader. If you've not done that you'll have to do it first and the process of unlocking will wipe the device.

Quote from Chainfire.
Acquiring root without modifying the boot images is still under investigation. Please note that the current method will not be officially supported. Future roots may require a clean system: we are at a very early stage of root for 6.0, methods used are subject to change.

I'd download the factory image and update to the latest build. you can edit the "flash-all.bat" so that it doesn't wipe your phone. Change the command
"fastboot -w update" to
"fastboot update"
to preserve your data.
I have re-opened this thread, because the linked thread isn't the same - this isn't a duplicate.

Just boot loops for me , even with Chainfire's boot.img. Is it necessary to do the steps one right after another?
Neat! Glad it is all happening quickly. I think I want to keep encryption, so I will probably wait to root and install TWRP until wiping data to remove encryption is no longer necessary.
Can someone please confirm if the damn fingerprint sensor still works after rooting?

Have you tried Odin to do the flashing? While not the same device, I have rooted my SM-A526B without TWRP by patching the boot image with Magisk and then copying over the patched boot.img file to a computer, then finally flashed it over using Odin.
I have played with TWRP and Odin in the past with other phones; But I don't feel comfortable experimenting with this phone since it's my only source of work right know. After the process is proved ok by other people with the exact same model as mine, I can't risk experimenting like I have done other times.

This won't work on Samsung "U" variant phones because of their locked bootloader. Once you modify boot.img with Magisk, the phone will automatically detect it as custom firmware and it won't allow it to be flashed because of locked BL.

ONE CLICK ROOTING TOOLS

Is there any one click rooting tools that work with Android 9 - 11? Preferably 10 - 11. I want to root my droid (I have an AT&T LG G8 Thinq) and I don't want to unlock my bootloader. Please don't say "C'mon dude just unlock your bootloader", I'm looking for an actual answer(s) here. Spyware or not. By one click root tool I mean something like a tool that you can press a or a few buttons and it roots your handset. Yes I'm aware many of great old ones are spyware.

Can't someone just flash TWRP or something else and take a looksee in ALL my files? Or flash something to bypass the lockscreen?
If I could bootloader lock it while having TWRP and Lineage OS that'd be GREAT, but unfortunately we don't have the signatures for that ) :

It is possible to have LinageOS with a locked bootloader. You can relock it and revert back to stock recovery, so people can not flash anything to bypass your lock screen. This is very common for OnePlus devices. You can sell it and buy a OnePlus, throw your phone.

No, you just need a OnePlus device. OnePlus allows a self-signed signature, you can generate it yourself, and no leak is required.

Only works with some OnePlus devices. You can sign your ROM with your self-signed certificate. You can modify your ROM to whatever you want(including root) then just sign it, flash it, and re-lock. The bootloader now checks your self-signed certificate.
I don't think your needs can be fulfilled with your current device, maybe you have to sell your device.

Only works with some OnePlus devices. You can sign your ROM with your self-signed certificate. You can modify your ROM to whatever you want(including root) then just sign it, flash it, and re-lock. The bootloader now checks your self-signed certificate.
I don't think your needs can be fulfilled with your current device, maybe you have to sell your device.

So basically with a OnePlus I could just flash whatever I want and relock as long as the ROM is flashed LAST?
Also what's so hard about getting a signature? Why can't someone just pull it from the existing stockROM and put it on a their own ROM, so they can relock an Xperia or LG or something with a custom ROM?

Yes, and you also need to build and sign the ROM with your self-signed key and flash the custom key to the partition via the following
fastboot flash avb_custom_key

You can not simply use the prebuilt ROM downloaded from somewhere and re-lock, it will not work because it is not signed with your self-signed key.

lol, impossible. If what you said is possible, then SSL will be a piece of * because everyone can pull the signature simply by visiting a site. You need to learn what is "private key" and "public key". You need a "private key" to sign a thing and that private key is secret.
OK, so the solution is... Break into LG headquarters and obtain the key signatures and spread'em all for the world to see!
The less exciting options include infiltration or bribery...

Also with unlocked BL, can't someone just flash TWRP and delete security stuff to bypass the lockscreen?

I know , but I mean if it's NOT relocked!
get an oneplus device and that's all, one clicking root tools are unusable for a while..... or just unlock your bootloader (on AT&T you can't, i guess) . and after you wanna sell the phone, reflash stock ROM and RELOCK THE BOOTLOADER.
