can i backup my TA partition on 28.0.a.8.272 (5.0.2) ???
[Xperia Z4/Z3+ General] rameses:
I've just got a Z3+ after years of having Samsung phones, which I've rooted, flashed etc. I've followed the guide in the OP but so far have not managed to get past downgrading the ROM to lollipop. The ROM appears to flash ok using flashtool but when the phone boots I get a loop of errors, "com.process.android.phone has stopped" and "com.process.acore has stopped". The only option is to click "ok" on the messages and then the phone reboots. I can't get passed this stage to do anything else. Are there any specific options I need to select in flashtool (current nothing is selected)? I'm using the latest version and all drivers are installed. I've reflashed the ROM a few times but get the same errors. Any advice on how to resolve would be appreciated.
[Xperia Z4/Z3+ General] grinna:
Try select the wipe options APPS_LOG, DIAG and USERDATA on flashtool
[Xperia Z4/Z3+ General] rameses:
This is turning out to be hard work. I've managed now to downgrade to Lollipop following the advise above about wipe options. Along the way I had to uninstall and reinstall flashtool on a couple of times on different PCs.

I've now got E6553_28.0.A.266_1295-4730_R8A.ftf installed on the phone but can't work out how to set bootloader unlock allowed to "yes". All security and device administrator options are deactivated, USB debugging is on. Where do I go from here?

I'm looking to root my phone and I'm assuming that the bootloader needs to be unlocked for this.

Hi All,

First of all, I like to thank you for your work and assistance. I have a (maybe) newbe-Question. As far as I understand Emma and its documentation, that flashing with it only works with unlocked phone. But I need to Flash 28.0.A.8.266 before I can do the TA-Backup. So How can I do the "clean flash to 28.0.A.8.266"?

Regard and Thanks for your help.

You need to download the 266 ftf file and flash all of it onto your phone using a tool called androxyde flashtool. There ought to be a million tutorials on how to use the flash tool if you Google it.

Download the stock rom which is given in description and use flashtool to flash the rom.

For drivers use 'drivers' folder in flashtool installed directory and install z3+ drivers.

I can't Restore TA with iovyroot

it shows an error: Device Not Supported

My Device Is Xperia Z3+ E6553
[Xperia Z4/Z3+ General] prasad.asr1978@gmail.com:
First, you have to flash Lollipop .266 Firmware -> USB Debugging Mode On -> command prompt & change directory to the IOVY Folder and run the command -> type the key word "Yes I want" exactly (case sensitive & without "")

Then it will definitely works. I done it several times and got 100% success:good::)

Hi there, any solution for safe unlocking bootloader on z3+ dual mm? I can't unlock, I tried with the two imei without success.

I think i have all required drivers installed because I can flash normally ftf with flashtool. Please help.
[Xperia Z4/Z3+ General] prasad.asr1978@gmail.com:
Read the Post 2 - 3 times thoroughly then you will automatically understand.

This post having all answers to many FAQs and safety tips.

Have you backed up your DRM Keys (TA Partition)? it is very important to keep the DRM Keys backup for getting back the warranty (if it is still under one year)

after that you need to request Sony official site for BL unlocking code by sumbitting IMEI Number.

Then using flashtool, you can unlock the BL.

[Xperia Z4/Z3+ General] prasad.asr1978@gmail.com:
If you flash DRM Fixed (Patched) Kernel, then you will not loose any features. All features work like as before unloading bootloader

Guy. I have a Z3+ dual and i wanna sell it. Só, i wanna restores it as original state. I makes a downgrade to 266 firmware then use ivyroot to restore the backup That i create from itself. The command works fine. When i check the status everything appears restored. No line for FIDO_KEYS. So, i update to Nougat, via Ota. Alter That, i check the status again and appears a link for FIDO_KEYS at this time but itself says: "not provisioned". I spend all My Day to try to fix it but i won't the able to make it works. My device don't have FIDO_KEYS? It's normal don't have it?

question

if i just root the phone, do i lose the keys if i do not open the bootloader?

So if i just root and i do not open the bootloader, do i lose the keys?
[Xperia Z4/Z3+ General] najoor:
If you do not unlock the bootloader you do not lose the keys, but I don't know how you can root the phone without unlocking the bootloader.
[Xperia Z4/Z3+ General] cashflow67:
You cannot root the phone wtihout unlocking bootloader. First Unlock Bootloader then root phone. But be careful. Before unlock bootloader, back up your TA Partition

Hello! I'M new to the Z4 and looking for improvements

is it worth to root this phone? I've been through popular development threads of the Z4, the one that i have my eyes on is the lineage os 14.1 nightly.... especially when it's lighter and probably handles high temperatures and workload better than stock. But again it's still in development and things can go wrong.... so what are the risks? and what are your recommendations?
[Xperia Z4/Z3+ General] Sangeeth Mk:
i have one doubt, if i root in Lollipop and backup TA PARTITION / DRM KEYS... can i restore it to Marshmallow or Nougat without any error?... i mean i need root & Complete TA & DRM KEYS should be in Nougat... All sony app should be working. is there anyone who did like this?.. it will be helpful if you share your experiences..
[Xperia Z4/Z3+ General] DiamondPlus:
You don't need root to back up your TA Partition if you're using ivy root v0.4 (as i followed the guide) but you have to downgrade to lollipop to get it to work. You can downgrade using Flashtool, i haven't tried re-installing official stock rom (so i can't tell you much about it) , but ivy root tool works flawlessly as i successfully backed up and restored TA Partition without the need of root.
[Xperia Z4/Z3+ General] teamz111:
Awesome!!!!

Man, thank u.
[Xperia Z4/Z3+ General] Sangeeth Mk:
I'm asking that i required root, without Recovery it's not possible to root in Android N or M.. so i have decided to do that first root in Lollipop & backup whole TA/DRM keys.. and later flash stock Android N then add Recovery by unlocking Bootloader, then root the device after that relock bootloader and then restore TA/DRM keys.. I'm asking is it possible?.. without any error.
[Xperia Z4/Z3+ General] DiamondPlus:
I have no idea about re-flashing stock ROM with recovery and root on (bootloader must be unlocked for root and recovery to work??), but thanks to this guide I managed to properly back up TA Partitions before rooting or unlocking the bootloader (so that I can restore TA, relock bootloader and then flash stock....if I ever needed to).. Now my Xperia z4 dual is running Lineage OS and performance is better than stock imo, but flashing it was a long and tedious (not quite noob-friendly :rolleyes: )

hi all. i have Z 3 + Dual 6533, on android 7 i try to flash android 6 before backuping TA partitions; but the device keep rebooting; is there a way to unlock bootloader in android 7 with keeping drm keys; because i like custom roms.
[Xperia Z4/Z3+ General] prasad.asr1978@gmail.com:
I think, you have not done Android 6 with full wipe (Caches, Data & System). You can reflash Android 6 with full wipe, then it will boot normal.

Note: For backing up DRM Keys, you need to flash Lollipop (E6533_28.0.A.8.266) to use Iovyroot tool. This version only support for Z3+ for backing up or restoring DRM Keys.

i need to back up TA partition not drm keys; what is the easy way to do that? i am on android 7 ; and how to downgrade to android 6 or 5? thanks in advance.
[Xperia Z4/Z3+ General] prasad.asr1978@gmail.com:
1. TA Partition is contains DRM Keys (both meaning almost same)

2. To get back your warranty, you need to restore TA Partition and need to lock bootloader, else it is not required. Patched / Custom kernel will do the job.

3. You can flash any version of android (upgrade or downgrade) without unlocking bootloader using FLASH TOOL. But, you need to select all the check boxes of the following in wipe section APPS_LOG, DIAG, PERSIST, SSD & USERDATA (flash tool screenshot enclosed for reference)

Note: Please read about Patched Kernel (DRM Fixed) for Stock ROM, Custom Kernel for Stock ROM, Switching of "My Xperia" (required for Patched / Custom Kernel, else phone will be soft bricked), USB Debugging Mode and other topics for experimenting with your phone / Stock ROM.

Thanks for this thread! I have my Z3+ setup with TWRP, root, and running firmware version E6553_Customized US_1294-9984_32.2.A.5.11_R3C. The issue I'm running into is that there's a newer firmware update; version E6553_Customized US_1294-9984_32.4.A.1.54_R2E and no matter how I try to install it -- either by downloading the fileset decrypt and creating the ftf with flashtool or by creating an update zip with prfcreator -- the phone won't boot into that system. It just bootloops. I also noticed that rootkernel doesn't build the twrp package with the latest version like it does with the version I currently have installed. One last thing. I noticed under XperiFirm there's an option for an update; version 32.3.A.0.376 / R2D. However, when I download that it's just a .pkg file and I have no idea what to do with it.

my Bootloader Unlock Allowed = NO

i have googled and searched on this forum with no result..

countless time i flashed .FTF files from 6.0 to the latest..

still Not Allowed

USB Debugging => ON

Unknown Source => ON

MyXperia => Not Activated (i even force stopped the service)

Find My Device (Any Similar) => Not Activated

Location => OFF

On latest build (7.11) there is "Allow OEM Unlock", i switched it ON, but still cannot unlock the bootloader.

i tried using the latest version of Flashtool to Unlock..the problem persists.

Using the fastboot command written in Sony official web, obtained the unlock code, but failed.

What should i do now?

Which ROM i should flash to have my phone Unlock Allowed = YES ???

Please i need a serious help, not a silly question like "Why do you need to unlock?"

i have to root this phone urgently, it is for my job/work which i cannot say in specific.

Thank you very much.

Hi,

I have this box bought on GreaBest website. The first I received was defect and crashed every 5 mins of usage (no idea why). I keep it and for some euros more I got a second one that it is OK.

The powerful of this box is very impressive. Fast as a standard phone for a cheap price. The defect one is now working with the CPU locked to 1,3Ghz max but is slower.

Sometimes I get some crash but it's quite OK. I want to integrate this box in my car as car PC.

I replaced the standard TV launcher by nova by I have a main issue: The background tasks are always killed. I can't keep Waze or Google play music running in background. I try to understand why it doesn't behave as a standard tablet but I have not yet the answer. If somebody can hepl me!
[Android Stick & Console AMLogic based Computers] Ilgard:
I've another box with the same issue. I don't know why there is no multitasking.
[Android Stick & Console AMLogic based Computers] redglory:
Are you sure that apps are not running at all?

Are you using any widget on nova launcher to show running apps? It could be some kind of sync problem between the OS and perhaps a widget?
[Android Stick & Console AMLogic based Computers] ed_bracam:
I don't know but when I'm using Waze or Google play music, if I use home key, the application is stopped (deseappear from the tray).

Another issue is the TV box virtual button style. I want to increase the DPI of the interface (to display on a 6,5 inch Car display in 800x480) and the standard android TV doesn't work on more than 190dpi. I would like to have a simple one.
[Android Stick & Console AMLogic based Computers] redglory:
Can you check if they are running? try this

For the DPI settings if you are rooted:

Method I – Do it from the phone on a Rooted ROM

1. Open Root Explorer.
2. Go to /system
3. Click on Mount RW (It should appear as Mount RO, that’s when it is correct!)
4. Look for build.prop. Long press on the file and press Open file in Editor
5. Scroll down to ro.sf.lcd_density=240
6. Change the value to anywhere between 180 and 240. The lower the value, the higher density your screen will have.
7. Click on the Menu button, and Save and Exit.
8. Reboot.

Method II – Before flashing a Custom ROM (Including AOSP ROMs for your phone)

1. Open the zip file containing the custom ROM.
2. Navigate to System Folder, then extract build.prop to your Desktop.
3. Edit the file using Notepad or EditPad or Notepad++
4. Click Ctrl + F(Search) and enter ‘ro.sf.lcd_density’ or navigate to this line.
5. Change the value to your desired (Higher Value = Bigger font and lower density, Lower Value = Higher Density and smaller font)
6. Save the build.prop file and replace back into the zip file in the same place.
7. Flash the Custom ROM as per directions.
[Android Stick & Console AMLogic based Computers] ed_bracam:
I just checked, the application is not anymore in memory. Killed by the go to home function. How is it possible!!??

I checked with google launcher. Same issue

For the DPI, I use a DPI changer application from the market that works great. And I can confim you the softkey ribbon is not working properly with a DPI equal or more than 200. The ribbon goes to the left side and a part of the screen is not usable anymore. Reboot needed. 190dpi is OK.

I want to simplify it removinf some buttons, it should help.

But the home button killing applications is my real problem
