[Sony Cross-Device General] AndreyAleks:
I have Sony Xperia XA2 Ultra H4233 phone and Lineage OS on it. I wanted to update my firmware to the latest available using that guide (maintainer wrote it).

I downloaded firmware files using XperiFirm. I select "Hong Kong" regional edition (see attach 1), but previously there was different one (maybe it's important?). Once it downloaded I remove these files (just like mentioned in guide):

- boot_X-FLASH-ALL-18AE_0x00.hash

- boot_X-FLASH-ALL-18AE.sin

- persist_X-FLASH-ALL-18AE_0x00.hash

- persist_X-FLASH-ALL-18AE.sin

- system_other_X-FLASH-ALL-18AE_0x00.hash

- system_other_X-FLASH-ALL-18AE.sin

- system_other_X-FLASH-ALL-9B8D_0x00.hash

- system_X-FLASH-ALL-18AE_0x00.hash

- system_X-FLASH-ALL-18AE.sin

- system_X-FLASH-ALL-9B8D_0x00.hash

- userdata_X-FLASH-CUST-18AE.sin

- vendor_X-FLASH-ALL-18AE_0x00.hash

- vendor_X-FLASH-ALL-18AE.sin

- vendor_X-FLASH-ALL-9B8D_0x00.hash

There's no simlock.ta in the list by the way, so I didn't delete it.

I turned off my phone and boot it in 'Flash Mode' (green light).

I copied newflasher.exe to that directory (H4233_Customized HK_50.2.A.3.77-R3B-orig) and start it:

newflasher.exe v42 by Munjeni @ 2017/2020

Determining available free space by GetDiskFreeSpaceEx:

Available space to caller = 140718 MB
Total space on current drive = 238467 MB
Free space on drive = 140718 MB

Reboot mode at the end of flashing:
typa 'a' for reboot to android, type 'f' for reboot to fastboot, type 's' for reboot to same mode, type 'p' for poweroff, and press ENTER.
p

Optional step! Type 'y' and press ENTER if you need GordonGate flash driver, or type 'n' to skip.
This creates GordonGate driver installer in the same dir with newflasher.exe!

Optional step! Type 'y' and press ENTER if you want dump trim area, or type 'n' and press ENTER to skip.
Do in mind this doesn't dump drm key since sake authentifiction is need for that! But it is recommend to have dump in case hard brick!

I see "Processing simlock.ta", it's not flashed?

Next, after closing newflasher I disconnect the USB cable, and then start the phone (according to guide).

My phone starts, it asked me PIN code for my SimCard (does it mean that the problem is not in 'simlock.ta'?), then - graphical passkey. When boot process is finished, I can't call - it returns me "Turn off Airplane mode to make a call." (but it's off). The indicator of cellular network signal strength is at 0 with little cross (see attach 2).

WiFi doesn't work normally - it doesn't see network on 13 channel (2472 MHz), other is visible, bluetooth is OK.

Well, accordind to that guide I have to flash FW to second slot too. But I didn't do anything else.

One thing I've tried: reboot to 'fastboot mode' and switch to another slot to see will it return back.

But there's the same on slot b.

I used Newflasher 2 years ago without problems (same guide for firmware update). But what was wrong in my actions now?

Sorry for big post.
