[Sony Xperia XZ2 Compact Questions & Answers] Quarzkopf:
Hello

Yesterday I tried (Xperia XZ2 Compact H8324) to flash on the new Android 9.

My device was built in Hong Kong.

I went like this:

First I downloaded the current German Android 9 Stock Rome via Xperifirm. H8324_Customized DE_1313-6204_52.0.A.3.84_R2B

Before the flash, I created the * .ftf file in flash tool 0.9.25.0, as shown in a Youtube video. The whole thing worked fine.

Then I put my device into Flash mode and integrated the latest drivers into my PC.

Before I could start the flash process, I had to move the *. Fsc script from the folder "devices \ H83XX" in the folder "my devices" and rename in the current firmware. Since he gave me the message when starting the flash process that no update script would be available.

Then the flash process started asking if he should skip certain things stored in the script. Of course I confirmed that.

The flash process ran without any further error message and ended with the message that the flash was successful.

However, after starting the Xperia, the message "Your device is corrupted - it can not be trusted" was displayed. The device shuts down after 5 seconds.

Fortunately, I was able to recover my original firmware through the PC Companion.

Can someone tell me where I might have made a mistake on the way and how can I fix this? I would like to have Android 9, but that has not arrived in Hong Kong yet.

This is my first tutorial, hope you enjoy it and take you further.

Thank you first to juandiazmora

So you get Android 9 on your smartphone without any regional restrictions.

The following programs are required: Xperifirm, flashtool 0.9.25.0

1. Download the Rome at Xperifirm which is compatible with your device and you want it. For me, the firmware was unpacked directly by Xperifirm otherwise uses Flashtool Tools> Bundles> FILESET Decrypt

!!! Important with the downloaded files the "fwinfo.xml delete" !!!

2. In the Flash tool go to Tools> Bundles> Create

2.1 There you choose the folder in which the firmware is located.

2.2 Then select your device at Device.

2.3 When branding enter your country version. In my case Germany.

2.4 In version your firmware version you want to install.

2.5 Now important and careful. With folders list you add all files except * .ta files to the firmware content.

2.6 Then click Create and wait.

3. Adapt Flashtool. Go to the folders "Users" \ flashTool \ devices \ H82XX and the

"User". \ Flash tool \ devices \ H83XX

3.1 Copies the 52.fsc from the H82XX to the H83XX

Deletes the 51.1.fsc

3.2 Then copy the complete folder H83XX into the folder "User" \. FlashTool \ mydevices

4. Connect the mobile phone in Flash mode to the PC. Do not forget to install the appropriate driver. Flashtool also provides drivers and Xperia Companion.

4.1 If everything is ready then go to step 5.

*

5. Flashing

5.1 Click on the flash symbol in the flash tool.

5.2 Select flash mode

5.3 For Source folder, select the folder with the previously created firmware file in * .ftf.

5.4 Select Device for Device Filter.

5.5 At Firmwares, select your created firmware.

5.6 For Wipe Sin, select APPSLOG / USERDATA

5.7 Select Disable final verification.

5.8 Flash

6. When flashing, he asks if he should use the 52.fsc.

Simply confirm everything then works well.

For me it all worked out but of course I take no guarantees. Everything at your own risk.
