Open My Xperia after UB still get brick? - Xperia Z4 Tablet Q&A, Help & Troubleshooting

Sorry for my bad English but i saw Z4 Tablet now listed in official Sony Developer page for Unlock Bootloader. So if I selected Z4 Tablet in drop-down list to Unlock Bootloader my Z4 Tablet won't get brick even I open My Xperia, right?

If you enable (not just opening), your device will brick.

I following your guide but i saw you choose Z3 Tablet Compact in devices list, but now Sony added Z4 Tablet in devices list, so I think if we UB choose Z4T we won't get brick :highfive:

It's old guide now...
I'll update it, but choosing Z3TC was just a workaround to get unlock code.
Actually Sony generate unlock code based on IMEI, so device list won't affect anything.

Do you have fastboot drivers? What does it say when you enter commands?
You can try re-install adb and fastboot via

Hi!
Had the same problem! Wiped the tablet and after it it worked to unlock the Bootloader w/o problems.
It is because of MyXperia beeing active.
I could not disable it in device administration so i wiped the tablet and after that everything was ok.

Hi All
I used Sony to unlock my boot-loader, everything went well but when I checked my status it says rooting status unknown.

I don't even get to fastboot part - every time I reboot with adb reboot bootloader the tablet goes into some mode with a black screen, green led indicator and fastboot devices returning nothing.
At the same time the device is recognized by windows as something S1???? and unknown driver, and I totally failed to find a proper driver for that.
Any help will be appreciated. Btw, Windows 10 here

Necro to say: YES, you can run "fastboot oem lock" to RELOCK the bootloader. "fastboot getvar unlocked" returns "unlocked: no".
Just tried it on my (two hour old) phone here.

Fastboot getvar all retrieves nothing

Hi guys!
A little background. I am trying to unlock the bootloader, after seeing the root status: unknown, a second time after re-flashing back to stock rom. I could unlock the bootloader perfectly fine on the first try on firmware .251 but after updating to .260, the
Code:
fastboot -i 0x0fce oem unlock 0x<key>
command keeps failing. I was trying to flash a custom rom from FreeXperia, but after several attempts of not being able to send the system.img into the tablet, I decided to re-flash to stock using Flashtool, and had selected all the option for wipe and no exclude.
Which leads to my question: Does the
Code:
fastboot getvar all
retrieves anything at all? I also tried
Code:
fastboot getvar boot
fastboot getvar version-main
but also retrieves nothing.
This is the log:
Code:

Hi, thanks for the reply! I was trying to get back root and unlock bootloader after splendidly failing to successfully flash a custom rom to my Z4 tablet. I was searching around Google for the remote: command not allowed error, and actually found out that some of the users actually have output for the getvar all command, which was bootloader version information and other stuff. I should also point out that I have successfully unlocked the bootloader the first time but not the second time.
Another question: Will downgrading the firmware change the rooting status in the service menu?
Edit: Will re-flashing the stock rom lock the bootloader?
Going to try the link you posted! Will report back if there's any disaster that I've made.
you better search here on XDA and not on the web
SONY devices are a bit special in terms of partitions and bootloaders:
http://forum.xda-developers.com/crossdevice-dev/sony/noob-guide-to-sony-ericsson-xperia-t3209012
AFAIK bootloader stays unlocked whatever you flash after unlocking and only using Flashtool or SONY PC Companoin (the latter useless for unlocked devices) you should be on the safe side.
fastboot flash ... is a bit more dangerous but I would never flash anything were I have a hunch the developer is taking too many chances and were there is no README. And it really has to be for your specific device!
Sometimes I think people complaining here have flashed obscure phone ROMs to their tablet or Wifi ROM to their LTE device or any weird pre Lollipop root tricks (there are scams easiliy found via web search).
I just tried downloading the Flashtool from Sony's website. The Emma one.
However, the program says that my bootloader is locked for some odd reason. I'm inclined to think I am in a state where I can't unlock my bootloader any more though.
I also did enable My Xperia after I reflashed the stock rom during the initial setup, but immediately deactivated it. I wonder if this is causing it to have this error.
the fora for newer Xperia devices are plastered with MyXperia "accidents"

Emma is useless. Does not work on our Lollipop devices. Updates of Emma seem to be automatic but no improvement. Maybe they forgot to switch off their update bot.
You bricked your device.
From SONY (READ before you do risky things!!!):
After unlocking your device, you should not enable My Xperia (found in the settings menu under security on some devices running Android 5.0) as this might cause the device to malfunction.

I do not think so though - if you could unlock the MyXperia Software would be no protection at all. Thieves could just unlock the BL of the stolen device and lough at SONY.

Alright! Thanks for the help! I guess no more rooting for me then. I'll try reflashing the stock rom again and see what are the results.
Reflashing doesn't change the rooting status. So a reminder to all: Don't enable My Xperia.

Question how to use Magisk root this device ?

i try the version of Magisk 23.0 but this is not worked.
It's the same with all other Xperia devices without customise recovery.
You first use Unsin (can find it in XDA) to the boot_blahblahblah.sin from stock firmware for unsin it. Therefore you will see a .IMG is generated.
Second, you transfer the .IMG to your phone, and use Magisk to patch (install - select file and patch) the boot file.
After it's patched (you can find it in the Download folder). Transfer the patched one back to your PC, and make phone enter fastboot mode (or the blue light mode). Then you run this command on Windows Shell (Google it, it's easy)
Fastboot flash boot the_file_name.img
After it's done, boot into your phone, you can find icon of Magisk, install it, and your phone is rooted in this stage.
Nevermind figured it out

Sorted it? Rooted mine earlier on. To unlock the bootloader you can just pick Xperia 1 or 1II it doesn't matter 1III will be added eventually but doesn't make a difference.
