[Q] Wierd 4.4.4 to 5.0.1 Update Issue

I am trying to update my Note 4 OTA and am running into an issue..
Both my phone and SD card are encrypted. My phone is stock. Previous updates I have done via Samsung Kies.
When I update it, it downloads the package and goes through the reboot sequence. When it starts the update process, it gets to about 2% and then says that the update failed and reboots and restores the previous settings. If I try to update via Kies, it goes through all of the screens and when I click the OK on the screen that says to not try to use the phone during the update, it just goes off into lala land and doesn't do anything at all..
Does anyone have any ideas as to what could be going on?
Thank you for your assistance.

Do you have reactivation lock enabled
BAD ASS NOTE 4

No. Reactivation lock is disabled. I verified it just in case, I have never used the feature.

I dunno man. By encrypted what do you mean. Knox or ????
BAD ASS NOTE 4

No. I mean I used the on-board encryption tool to encrypt the SD card and the internal phone storage. In the Security settings. I encrypted the device and the external SD card.

U might want ask a dev. U might get faster answer

Have you tried to Odin the update?

You will need to disable the encryption before going forward. The encryption is doing what it's supposed to do; preventing writing new code.

Will I be able to decrypt it without losing the data?

Disabling the encryption was the answer. I did not lose any data.
I would like to thank everyone for their assistance.

[Q] Root and Encryption? (Bootloader locked, Rooted, Firmware 23.0.1.A.5.77)

Hello everyone
I have now finally been able to root my beautiful Sony Xperia Z3 Compact. The bootloader is still locked. I did downgrade the Firmware in order to root the phone. Afterwards I made a backup of the DRM Keys via TA Backup. Additionally I updated the Firmware to 23.0.1.A.5.77. As the bootloader is still locked I did not install any kind of custom ROM and I am yet not planning to do so. The Sony ROM will probably do a good job. (My old phone is a Sony Xperia P which is now running with Root Sony's ROM since 3 years at least)
I am running on KitKat 4.4 and also not planning to change. I have a 64GB SD card in my phone as well.
Now my question:
Can I still use the encryption function or will this interfere or make problems because I have root (Bootloop)?
I am not planning to encrypt the SD card because I do not need encryption on the SD card but encryption for the Android System would be nice.
Thanks for your help guys :good:
Best wishes,
Dicey

No idea guys? Did no one ever try this before?

I'd like to know this as well.

I tried this today. Left it encrypting and when I came back it said encryption had been interrupted and it then did a factory reset, after which I was unable to enter custom recovery.. As I had chosen to encrypt the SD I was left with an empty SD card too.
Somehow I kept root so I was able to install XZDualRecovery again and then restore from nandroid backup.
There's a thread on androidforums where Samsung owners have reported success with temporarily disabling SuperSU while running the encryption.

Anyone tried this method or found another way to achieve root + encryption? It's the only thing keeping me from rooting again.

Dirty ROOT solution - for unlocked BL

Abandoned
This rooting method is deprecated. Use TWRP for Z5C instead.
Old post:
I have rooted my Z5 Compact and figured you might want a short how-to.
Disclaimer
I am well aware that this is not the nicest method of rooting, but I got the phone a few hours ago and haven't got the time to put together a better way.

Guide
First, you need to unlock you bootloader (I know, I know, now stop weeping :crying::crying::crying
A rooted device does not boot using default kernel, so you need to install an insecure kernel.
I am using a repacked Zombie b1 kernel, with a small modification (wrong owner on all files in ramdisk).
All credits fly out to @Tommy-Geenexus : [Kernel][Sony5.x][Z5C]Zombie[13.10.15]
Flash using:
Code:
fastboot flash boot zombie_b1_fixed.img
Reboot your phone using:
Code:
fastboot reboot
And verify that it works as expected.
Now, reboot your phone to bootloader again (see info how to at the end of post).
Then issue:
Code:
fastboot boot recovery.img
This recovery is partly broken, but it works well enough to install root.
Thanks to @AndroPlus for TWRP code.
The phone will boot to a black screen, but you can connect to it using ADB.
You need to manually mount the system and userdata partition by issuing:
Code:
adb shell mount /dev/block/platform/soc.0/by-name/system /system
adb shell mount /dev/block/platform/soc.0/by-name/userdata /data
If you get this error:
mount: mounting /dev/block/platform/soc.0/by-name/system on /system failed: No such file or directory
You probably just need to wait a while and try again.
You can also try this command (and then re-enter the mount commands above):
Code:
adb shell mount
adb shell cat /proc/partitions
If you got /system and /data to mount, you can now push SuperSU to the phone and install it:
Code:
adb push UPDATE-SuperSU-v2.46.zip /data/media/0/
adb shell twrp install /data/media/0/UPDATE-SuperSU-v2.46.zip
adb shell rm /data/media/0/UPDATE-SuperSU-v2.46.zip
If it all works, just reboot and enjoy root:
Code:
adb reboot
Files
zombie_b1_fixed.img
recovery.img
Extra info
Boot to bootloader by adb command:
Code:
adb reboot bootloader
or by turning off the phone, and then hold down VOL UP while plugging in the USB cable.

Thanks!!!!! I will try this as soon as I go home! will update you

what model do you have by the way? mine is E5823
Thanks

you are the greatest!!! THANKS SO MUCH!!!!!!!!!!!!!!!! it works on my model. dirty or not, as long as it works
UPDATE: OMG, after finally getting all my apps on, i was happy to put my SD card and sim in.
IT WOULD NOT TURN ON. it kept rebooting and the indicator flashed a few times.
after isolating the problem, it does this when the SD card is in. Sim card is fine..
- So I can use the phone without SD card, but as soon as i plug it in, it reboots.
- I've tried the SD card in my old phone and it works fine.
- i've also used a new SD card in it and it's rebooting.
Do you think this is hardware error? is there something in the above scripts that could've affected it?
The truth is i never tried it before i rooted it.. so i'm not sure if it's due to rooting..
Please help me!

That sounds really ominous
I got the phone yesterday and have not yet tried it with SIM or SD card, so I can't really tell you if it is due to the rooting.
The recovery commands or the root should not cause the SD to stop working. The custom kernel could possibly do it, but I doubt it. However, until I (or someone else) test a SD card while on root, I can't really say for sure.
Sorry

Can you please test when you get a chance? I've unroot using super su and have done a factory reset. Same result.
I've also put in a request for warranty... Great work though. Thanks for posting this!

My SanDisk Ultra 64GB is working just fine. No SIM card in the phone, though.
Note that I have upgraded to 32.0.A.5.32.

You guys noticed a change in the official camera app ? Does it still behaves the same and post process automatically images ?

Yeah, I'd like to know this as well. On the Z3c, Unlocking the bootloader lead to really ****ty images. Is this still the case? I don't care much about DRM, but the camera has to perform.

Is there anywhere that I can find a rundown on what I'll actually lose by unlocking the bootloader? I don't particularly care if the camera loses a little quality, and it seems like I probably don't care about any of the DRM stuff, either, but I would like to be sure.

I'm a little unclear on the losing of the DRM (if it is actually lost). Does this occur when you unlock or root?
(I realize you need to unlock in order to root).

It happened on unlock and it can't be reverted. DRM keys are unique for each xperia so flashing another TA partition from another xperia will brick your device.....

Hi, I read about the new TWRP method, but after flashing TWRP, what should I do for get root? Just flash SuperSU zip from Chainfire's site?

Is this... a warning? Or have you yourself never unlocked your bootloader?

Anyway to have Root AND device encryption?

Title says it all. Is there any known way to have root and device encryption still possible?
Thanks a lot.

Got it working with the stock ROM in the mean time. Just don't use TWRP to flash Magisk. Keep the stock recovery, Use Magisk Manager to patch boot.img (check tar format in settings) , then flash back via Odin, boot and factory reset. Done.
No luck with any custom ROM yet. Desperately looking for help. Would also pay quite a bit to have someone skilled looking into this. I don't want to keep the Korean ROM of my N950N

No, flashing with TWRP requires to format data. That step loses encryption.
For some reason it's then impossible with Magisk or pph root to just reencrypt the phone from a custom ROM. It dies with invalid encryption and looses all your data when you try.
It's a bit different with SuperSU. Here it thinks encryption went well and tries to mount it on next boot, but then fails.
From my current knowledge it seems it needs stock recovery to recreate an encrypted data partition that actually works. That's the bit I'm stuck now...

On the Snap version, using SamFail gets rid of encryption. There's no way to encrypt for us with root because of the 80% short coming.

Ah crap, didn't even think of that issue

Anyway, at least to me a phone without reliable encryption is not usable as daily driver. I wonder why this gets so little attention. I spend some days now trying to resolve this, but there is not much information out there or I'm not capable to dig it up.
I couldn't even find a clear statement, what it actually is that prevents TWRP to mount encrypted /data on modern Samsung phones.
I known they do their own SOC based hardware encryption, but what is it that TWRP can't get? Does the trusted zone not release the key if a custom binary boots? I really like to understand a bit more on how this actually works.
Thanks

Looking to install Magisk (root) you're phone? <unlocked bootloader, TWRP>: Android

I've always been a fan of rooting my Android phones...
For theming purposes and to install Magisk...
I had just gotten a Moto G Fast...but when I went to flash Magisk 21.4
I realized that all of my data was encrypted and that wasn't going to be
possible...
No big deal I thought I can just wipe/format data... For whatever reason
that didn't work and my data was still encrypted... So I left it alone
for a few days... I thought what the heck why not? I took my micro sd
Card from another phone I have and put it in my Moto G and wasn't long
before I realized that my micro sd was not encrypted and I was able to
Flash Magisk, V4A... And all the other files I wanted to...
I love Pixel phones but since they don't have an sd card slot.. I might be
Staying away from them until that changes
