Flash Issue - Sony Xperia XZ2 Premium Questions & Answers

I flashed a global model H8216 ROM on Sony Xperia XZ2 Sov37 Japanese variant.
Now i wanna revert back to Sov37 stock rom but flash tool says "the selected bundle doesn't match the device'
Whereas my device is sov37 and the rom also is sov37, please help to resolve the issue.
The main reason to revert back on sov37 rom is nfc missing driver draining the battery quickly.

[Q] Rogers Official Gingerbread Update Help

Sooooo, like alot of people here that either couldn't wait or didn't think we were getting the update, I flashed my x10a with a generic firmware(now an x10i). I believe my original region code was 1233-6929. My question is, how would I go about putting the official firmware back on? I've searched and can't seem to find out how to do this. Any help would be greatly appreciated.
According to this
http://forum.xda-developers.com/showthread.php?t=1186045
1233-6929 has been updated to 2.3. There is no need to go back to 2.1.
Did you not make a backup of the 2.1 ROM with xrecovery before you flashed 2.3?
Why do I get that feeling that I'm going to kick myself in the butt for not doing that? Anyway, I should have added the fact that I am currently on a generic gingerbread firmware but would like to know how to put the official update on my phone?
No, no you're fine unless you absolutely need to go back to Eclair.

Flash the 2.3 firmware for X10a with the flashtool. I've got to tell you, all the 2.3 upgrade has the same build number (3.0.1.G.0.75) and the firmware you are currently on is no different, except what the "model number" says on phone's property.
You can try updating the firmware through SEUS or PC Companion, but there will be no difference.....
Alright, thanks for the info. Looks like the owner of the thread you linked here doesn't have all the x10a kits added yet (which I'm assuming includes the Rogers one I mentioned) so I may have to wait for a bit before it's available for download so that I can use it with flashtool? The only reason why I want to go with the official update is because I've had a few glitches with the generic one I currently have. Every once in a while I get some error messages pop up on the screen, one that I can recall is "failed to create media transport" and some other ones. Plus if I ever plan on selling the phone, it probably would be best if it had the official update on it (just itching to get the galaxy s2).

[Q] Flashing a Stock ROM to the Xperia X2

Hello, XDA members
I've gotten my hands on a really cheap Xperia X2 that was originally sold in China, and as a result the entire interface is in Chinese. I've managed to find a copy of a generic English ROM, but I have no idea how to flash it.
I'm familiar with the process of flashing ROMs to the older Xperia X1, but that phone was built by HTC, so I'm going to assume the method is completely different for the Sony-built X2.
The file I've downloaded is X2_1233-7729_GENERIC_EN_R3AA035_CDF1234-0918_R10A.software
I've also downloaded a cab that will change the phone's region and allow the phone to install software from a different region if connected to the Sony update service. I don't have the phone yet, so I'm not able to do much testing. But the update software available from Sony's website only supports Android-based Xperia models.
So, I have two questions:
1. Does someone know how to take that funky .software file and flash it to the phone?
or
2. Can anyone verify that if I download an old copy of the update service, it will still be able to connect to Sony and download a ROM for the phone?

German Stock ROM ftf File

Hello,
Does anyone know where I would be able to get any (Customized DE) Stock ROM for the Xperia X Compact (F5321)? I found the site xperiafirmware.com but they only offer the CE Version. I also tried to download and unpack the German Version with XperiFirm. But I couldn't manage to bundle the files with Flashtool, since there was no Xperia X Compact to select from the Devices Menu. And I also didn't know which files exactly to include and which not. Also what about the files in the "boot" folder, should they be included? I also can't upgrade the Phone via the "Emma" Flash Tool from Sony either, because the phone isn't recognized by it.
So the simplest solution would be to just be able to get the Stock ROM ftf File from somewhere or someone and flash it via the Xperia (non official) Flashtool.
Thanks in advance for your help.
Best regards,
Simon
You have to close all windows except main flashtool after downloading. Then file will be created. Do you need nougat or marshmallow?
Since there is no operating system currently installed on the phone and the update from Marshmallow to Nougat failed. I guess Marshmallow would be the best option to recover the phone.
And even if I close all windows, I still can't select the Xperia X Compact in the Flashtool Devices Menu.
Which version do you use? Here you can download latest MM ftf.

Thanks a lot for the Link. Sorry for my late response but I was very busy lately. It all worked out well.

How to switch back to "factory"?

Hi,
I recently unlocked my XC to flash Sailfish. I just would like to know what's the best path to get back to the official Android? Or is it locked to AOSP definitely?
I guess flashing AOSP and then install Xperia specific apps (if present on the Play Store) should be doable, but I wonder if there is a more direct way.
Thanks.
Just found Emma. I was able to flash the factory image...except the TA partition of course, but it's not a big deal.

I think flashing via flashtool wiping everything should bring you back to the original form (except from Bootloader remaining unlocked). Then you have to gain back root, though (if I got your point).
Sorry for this later answer. @eresac it worked...almost.
Indeed it's pretty strange. I didn't notice first, Emma didn't offer to flash Android 8 but 6 instead ! Problem is now the XC never gets the notification to upgrade. Any idea how to change this?

I think Emma might offered you a firmware for non-retail device (ex. Demo unit in store, Review unit, Exchange unit at service center) which has no update and shouldn't be use as daily driver.
Try reflashing it with different firmware. If there isn't any different firmware to select in Emma, use Androxyde's flashtool instead.
Emma offers only one firmware. And this is 6.0.1.
Ok to flash a newer firmware with another tool, but where can I get a factory image?
You can download it from flashtool (via XperiFirm plugin) following this guide. The title said Marshmallow but this method is compatible with newer firmware too.
http://www.xperiablog.net/2016/03/12/install-xperia-marshmallow-using-flashtool-and-xperifirm-guide/
Also, make sure that the firmware you download has version number starting with 34.4 if you want Android 8.0

Can I use normal ROMs with the Japanese version?

Hey guys, I just ordered a cheap Japanese version of the X Compact, with model number SO-02J. Will I be able to use F5321 ROMs with it? It seems like I should be able to since they appear to be the exact same phone...but I'm not sure. If not, is it possible to root the Japanese version?
Thanks.
I seem to remember that the Japanese version of the phone required different firmware, that firmware versions produced for F5321 were not compatible. It's an entirely separate listing in XperiFirm.
But once I had a z3 compact so-02g. And I installed a global firmware on it successfully. What was missing in it the NFC driver which was causing a rapid ? drain. Otherwise worked well and I was thinking the same will happen again in xperia x compact case. Because you're trying to download rom from xperifirm but I'll download global rom from www.xperiablog.net and will select xperia x compact f5321 range.
The main reason for asking the question was that you can't download x compact SO-02j's oreo and nougat roms because you only can implement them by OTA. You only can download marshmallow and to upgrade the phone through OTA to nougat or oreo you'll required a nikimisi japan wifi NETWORK. Which won't be available in our region and in the result you may brick your device or restricted to 6.0.1 mm Japan rom.
I thought if someone already did the trick and I could take advantage from that experience.
I'm thinking to do this by myself and I'll let you know about my experience...
For a long long time I haven't bricked any of my device let's see what happens now...
Good luck; you seem to know what you're doing. I've never flashed individual components or "mixed and matched" myself, so I admire your bravery!
Can i convert or clone my current running stock rom (factory installed) to .ftf rom?
Thanks for the info...will get the phone tomorrow and see if what works and doesn't work....will report back here.
Do you have a Japanese X compact yourself?
Yes I got a Japanese SO-02J X compact.
But planning to flash it with global version rom.
Downloaded both roms a Russian generic of f5321 and so-02j nougat. Just in case if f5321's doesn't work will revert back it to so-02j stock nougat.
Will goto home for this experiment, still outside.

Well, looks like mine is "unlock bootloader allowed: no" so I won't be able to do any modding with this device. Oh well, it's still pretty cool. Has anyone managed to get oreo on this thing outside of Japan? I think the OTA update can only be downloaded in Japan....

Hey, how did your experiment go. Were you able to flash global firmware on SO-02J X compact.

No i didn't try that because i sold the phone... I was in search of a "boot loader unlock allowed: yes" phone and now happy with Sony Z3 D6603.
Unlocked it's boot loader and flashed it with carbon cr8 (android Q) an excellent and perfect ROM. Enjoying my phone...
