Im using the newflasher v43, now my Xperia 1ii is flash from HK version to SEA version
After flash to SEA version, my Xperia 1ii can use the VoLTE on Malaysia telco (Celcom)

1. Just download the firmware using XperiFirm
2. After finish download the firmware, you will get a folder with firmware version (like XQ-AT52_Customized SEA_58.1.A.5.280-R2B)
3. Extract the newflasher_v43, you u set alot file like newflasher.exe, newflasher.arm32 etc, copy all the file to your firmware folder
4. Now make your Xperia 1ii boot to FLASH MODE, back to the firmware folder, run newflasher.exe
5. Reboot mode at the end of flashing, I select poweroff, so i type "p" and ENTER
6. Optional step! Type 'y' and press ENTER if you need GordonGate flash driver, or type 'n' to skip. This I type 'n' to skip
7. Newflasher will start flash your Xperia 1ii
8. While newflasher ask if you want to flash persist img, just type 'n' and it will skip flashing persist
9. Waiting until finish, then power on ur Xperia 1ii and you will flash to SEA version (or other version your download)

is it correct to delete only persist.sin file before flash? (as told here: https://xdaforums.com/t/guide-flash...-xq-at51-with-flashtool.4119707/post-84866179)

Is this need delete any file before flash?
Or just only delete the persist_X-FLASH-ALL-2389.sin file?

I flashed mine from HK to SEA, basically you will need to download SEA fw with XperiFirm and then flash with newflasher.

In the newflasher, it will ask if you want to flash persist img, just type 'n' and it will skip flashing persist. And no, besides persist, there's nothing to worry about.

Anyway, if you are not sure, you can move persist img out of the firmware folder first and newflasher wont ask if you want to skip anymore.

Ps. Dump your TA with newflasher first just in case. (it will ask you to do so.)

please skip

 

[Gigio755]

work?

yes
only a tip if you will backup TA

extract newflasher in a folder .. backup your TA and then it will close

Now extract newflasher in the "XQ-AT52_Customized SEA_58.1.A.5.280-R2B" folder .. remove the persist_X-FLASH-ALL-2389.sin file and start flashing, that's all (and use the proper usb cable)

there is no need to delete the file as there will be a warning message you want to flash persist it or not. please select skip or no
