Flashback Xperia XZ2 SOV37 Back To Original AU Firmware - Sony Xperia XZ2 Questions & Answers

Hello everyone, I just want to ask. I've Xperia XZ2, it's AU Model (SOV37), using Global Firmware (H8216).
I want to flash back into it's original firmware in order to use the NFC.
I already download the Japan Firmware (SOV37_KDDI JP_52.0.C.5.295-R13B), but I'm afraid that it will sim-locked if I flash it.
I'm also afraid that since this device wasn't able to unlock the bootloader (since the Bootloader Unlocked Allowed: No), can I still flash the firmware?
Can anyone show to me step by step how to flash the firmware (Not flash the STOCK ROM)?
Thanks in advance.

as long as you delete all the .TA files there shouldn't be any problem, though the latest japan firmware available is android 9
not sure what you mean by firmware though, since technically what you trying to do is flashing a firmware as in stock rom

Sw update C150B140

Hi. I have a L09C150B140 from cosmote Greece.
Is there any update to this version?
Can I find this version and keep it for warranty purposes and just debrand to an other firmware?
Thanks.
Probably there is not an update available, probably you have the stock rom of your carrier, will recommend you to debrand the device and change you update area oeminfo, you shouldn't lose your warranty because you are flashing and installing an original and stock rom of Huawei.

Hello All
I have unlocked bootloader and rooted my P9, but have recentley seen an OTA come through to turn my current version to B160.
I understand that I need to flash a stock Rom in it's entirety (re-lock BL and lose root) before I can proceed with the OTA?
The issue I have now is that my current build number does not appear to be available anywhere as a stock rom. I am in the UK and with the 'Three' network.
If anyone can point me to the stock ROM for my build or can recommend another stock Rom to flash that will work without issues, I'd very much appreciate it? :good:

My device is Brazil 1802 USA - Could i flash Indian Stock Firmware ?

My device is 1802 firmware USA - BR
Could i flash Indian firmware stock, or will brick ?
I think if yes, its solve my problem, when i try flash oreo custom roms.
I lose IMEI ever, if i flash stock indian, and put custom oreo, baseband is the same, my IMEI remains...all right ?
Or brick ?
PS: this method persist.zip not ok for me, he make me lose IMEI when i put oreo, so, not want more this method.
Thanks for attention.

Just got a Docomo Xperia 1 ii. Did I screw myself?

I haven't been in the phone flashing game for a while. I'm not seeing many topics regarding my Xperia 1ii (Docomo version) Because there are locked bootloaders nowadays or something? Would like to flash a global ROM on it but I don't see official TWRP support for it either.
Not receiving the Android 12 updates either even though I should by now. I'm in South East Asia, is my location causing the update not to get pushed over?
using Japaneses model doesn't mean it always locked, i have AU version of xz1 that unlocked and have xz3 global that locked.. but yeah. most Japaneses model are locked. if you are locked. or only want to flash global. there no need to unlock it. or use twrp or other recovery. in fact flashing official rom doesn't even use recovery mode at all. it use download mode(if im not mistaking it)and with tool like xperia Firmware downloader and newflasher. you can flash any official rom to your docomo one.
BUT. REMEMBER!!
1.Japaneses smartphone use special nfc hardware that different than global. your nfc will go bye bye if you flash global rom in there.
2.careful. do research before flashing. xperia devices is not as easy as samsung or xiaomi. 1 mistake can be fatal. if lucky it only bootloop. but if unluck, from software/feature glitch, locked(sim/ubl) or just refuse to detected(A.k.a permanent dead)
i been use xperia devices since z4 era. and trust me it more scare to change official rom on locked devices than swap custom rom or install mod like magisk,etc on unlocked devices even manually modified system file are better than change to global on locked devices,

NEVER try to flash firmware from a different model number. You could permanently brick your device.
The only firmware you should flash on a S911B/DS is the S911B/DS firmware.
Odin won't let you flash anything that doesn't match up to your model #. I tried on a SM-S9110 with USA software and was soft bricked. The only fix was to unlock the bootloader and go back to flashing a compatible software.
