That is interesting. Mine still says "Your device has the latest available system updates".

same here, maybe it was just some sony app update

Newflasher didn't seem to work either. Fails to flash couple of the firmware, as well as bootloader specifically.

Newflasher v11 just came out, and i can confirm it works. If you get on the newer baseband and bootloader, you can fastboot flash the patched boot.img. TWRP is also available now

flasher v11 worked like a charm with my Sony Xperia XA2 Ultra H4213
after flashing started my device like a new device and everything was ok..

but the message on the boot still remains :
Your Device Software Can't be Checked for Corruption
Please Lock your Bootloader..

i dont know if there is a solutiuon for this matter ??

I'm having the same issue on the XA2 Ultra H3223 as well. ADB detects my device fine but when I go to the bootloader Fastboot doesn't detect the device and Device Manager (running Windows 10 x64) says the Android devices aren't installed. Yet I have the Fastboot devices installed via Minimal ADB And Fastboot. I feel like a dog chasing it's tail at this point. Normally I never have issues doing stuff like this as well.

I will take it you have already installed Sony USB drivers.
You may to check to see if you conflicting USB drivers.

The Sony XA2 Ultra device shows up when it's running normally. But when in the bootloader mode under Android this is the message Windows gives me.

The drivers for this device are not installed. (Code 28)

There are no compatible drivers for this device.

I tried using the "Latest USB Driver Windows" that Sony linked to with no success.

go into the device manager, update driver, select Android device, update driver, select driver, have disk, browse, navigate to the folder where you extracted the zip drivers for the XZ2, select the ini file.

that's what worked for me

how did you unlock the bootloader? i was told by sony that h3223 is not unlockable

H3223 Magisk root confirmed using unsin! Thank you so much!

EDIT: "Busybox for Android NDK" magisk module also installs and works without a hitch

I got it! These drivers finally let me get Fastboot working which in turn let me finish the bootloader unlock process. My XA2 Ultra is now unlocked with TWRP installed and Magisk rooted. Thanks for helping everyone involved! One thing I noticed is TWRP doesn't seem to want to stick even after flashing it (temp install via Fastboot then flashing the zip within TWRP for perm). Did I miss something?

If you have a 3rd party App such as GravityBox for Xposed or Quick Reboot from play store, you can reboot to recovery, but the only way to get in TWRP if you bootloop is through fastboot. but you can reboot to recovery with a 3rd party app if you sideloaded the zip

I'm having issues getting Xposed to install. Which version did you use? I tried using the 90.1 beta 3 SDK26 one but sadly that sends my phone into a freaking boot loop.

I feel like such a freaking noob lately with this phone. Thanks everyone for helping me.

Xposed worked on the earlier firmware I originally had, but then when I updated the firmware to the newest version, it bootlooped on me

it works on 50.1.A.4.102 and lower, 50.1.A.5.59 breaks it.

I flashed the older firmware, but the baseband version won't downgrade, not sure if sony has something preventing it from being downgraded, so I'm waiting on a new version of Xposed. I already reported the issue on GitHub

From what I see on the Xposed thread it's a bug in the current Sony firmware not just on the XA2 Ultra but other devices that is causing this. So hopefully either a work around is done or Sony fixes the issue themselves that is causing this. Thanks for the info. I was going nuts trying to figure out why I was boot looping after flashing Xposed.

thanks for the help 2 times on this lionh3art3d. that flash did not work i was still in a boot loop upon completion. So i tried something that actually worked. i flashed the original boot image that i pulled with sin. then i booted up and flashed the patch boot. boot loop again.... so after again flashing the original boot img, i uninstalled the xposed app and flashed patch boot, and all is well. everything was still set up too, apps and settings.

Hello, I am interested in installing custom recovery (twrp) and rooting with SuperSu. I have my hands around one XA2 Ultra, but so far I can't find anything on the web. If anyone has the solutions, please inform! Thanks.

I made this topic on the sony forums,
it is for xa2 bit it might work for the ultra too as they both have snapdragon 630.
Make a backup just in case the twrp is not compatible.
