I've received the ColorOS 11 update on my Chinese PDEM30 device. Since then the Google app is crashing and is not usable.

Any way to change the region on a Chinese device? I'd also like to have VoLTE and VoWiFi both of which are not an option on the Chinese rom.
[OPPO Find X2 Pro Guides, News, & Discussion] Sage:
you may need a factory reset.
[OPPO Find X2 Pro Guides, News, & Discussion] golemagg:
For? The Google ap crashing issue or the volte and VoWiFi?
[OPPO Find X2 Pro Guides, News, & Discussion] barantunc:
Hey there fellas, after the process everything works normal except my region setting is missing now, is that normal?

I have free EU version with 1 sim tray model. Let me tell you what I did in order: I changed my region to Singapore in settings, flashed Pakistani A.45 (I was A.46) , then unlocked by the software. Did dialing codes thing to change region to Singapore EX, then updated Android 11 C.05 then C.06. Build version is CPH2025SG_11_C.06 now.
[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
I've been wondering the same thing, the codes don't work on the Chinese version. I've tried copying some of the APKs from the EU version to my Chinese version, like the engineering apps, phone aps, etc. Also tried starting the engineering network app (that's the one that's changing the region) through ADB, but with no luck so far. To be honest I have no idea how these USSD codes work.

Anyway, have you tried clearing the cache of the Google app? Maybe a factory reset and reinstall all the Google services, play store, etc like Sage suggested might fix it.
[OPPO Find X2 Pro Guides, News, & Discussion] golemagg:
The Google app uninstalling and reinstalling a few times seemed to do the trick. However VoLTE and VoWifi are still not available as options and that is what my biggest problem in this device is currently. Need to find a solution for PDEM30 for this.
[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
Hmm, not sure you actually need to change the region in the phone settings to Singapore first. The language and region options on mine has moved to Settings / Additional Settings / Language & Region. Do you just see the language option only?
[OPPO Find X2 Pro Guides, News, & Discussion] barantunc:
So it is not supposed to be missing. Hmm. Now I am sure you dont need to change region setting before unlocking. However I didnt think it would cause such thing.

It is now Settings / Additional Settings / Language. Codes also wont work now. Havent tried unlocking again. As I said it is not a problem for now; but I might not get upcoming OTAs?

Got the Google feed to work by removing that awful smart assistant

---------- Post added at 02:32 PM ---------- Previous post was at 02:30 PM ----------

Well I changed to Singapore ex and they seem to get all the updates rather fast so I'm happy staying on that region and right after I upgraded to Android 11 I got another OTA right after reboot so otas are working

Can send me one sim tray ceramic black?

What am I doing wrong? I get the numbers on the left but no, okay on the right????
[OPPO Find X2 Pro Guides, News, & Discussion] kevinireland11:
Did you follow each and every step, I found it hard to find my ethernet adapter but I found it and then changed the properties then plugged my phone in and it came up the numbers on the left then I selected unlock and it flashed ok
[OPPO Find X2 Pro Guides, News, & Discussion] koloure2211:
Thank you for your swift response,

Yes I found my ethernet adapter, input the numbers,(correctly ?) I even disabled my WiFi adapter, (that's how the computer access the web) but nah?
[OPPO Find X2 Pro Guides, News, & Discussion] kevinireland11:
Have you enabled USB debugging in developer settings and set your phone to media transfer?

My OEM bootloader is unlocked to in developer settings but I don't think that's got to do with this

Then a pop up should come up on your phone, click allow
[OPPO Find X2 Pro Guides, News, & Discussion] koloure2211:
Yes to both, bit no toast message?
[OPPO Find X2 Pro Guides, News, & Discussion] kevinireland11:
So once you've done all that when you connect your phone you should see random numbers appear on the left hand side of that tool then click on unlock and wait a min and it should start flashing "ok" then exit the tool then you type them numbers *# into your keypad and should say (switched) as a toast message then delete that number and type in the other number *#
[OPPO Find X2 Pro Guides, News, & Discussion] koloure2211:
When I connect my mobile I get no random numbers till I click unlock,

Then they appear, but no okay on right pane?
[OPPO Find X2 Pro Guides, News, & Discussion] kevinireland11:
Are you trying this on a China phone or global
[OPPO Find X2 Pro Guides, News, & Discussion] koloure2211:
Global, my Chinese version already has Android 11.
[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
Sure, they're coming from China so will probably take a couple of weeks.
[OPPO Find X2 Pro Guides, News, & Discussion] kevinireland11:
Ahright, only think I can advise is to go right back to step one and re do the steps, maybe have missed out on something small, I'm not to sure I just followed the guide and got it right away.

Does anyone know what the best region to choose? Some regions give you theme store some don't some regions give 5g some don't same with call recording ect.... Is there a region that will just allow me to use everything? As well as receive updates
[OPPO Find X2 Pro Guides, News, & Discussion] koloure2211:
Thank you for your help
[OPPO Find X2 Pro Guides, News, & Discussion] Leuviah:
But is original oppo?

Inviato dal mio CPH2025 utilizzando Tapatalk
[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
I think I'm sticking with Singapore EX for now. Theme store, 5G, call recording all work, plus we know the OTAs work ok. Don't think anything is actually missing apart form the ringtone maker, but that might be software version more than region. On top of that it also enables dual SIM (which as far as I know is only standard in Singapore, Malaysia and Thailand.

Does 5G work on that MultiLingual EX, didn't think to check when I briefly switched? Also worried might not get updated on that one, or of we do we might lose featured after its updated.
[OPPO Find X2 Pro Guides, News, & Discussion] belloni:
I don't seem to get 5G on either Singapore EX or Multilingual EX unfortunatly, any other ideas?
[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
So you mean you can't see it in Settings, SIM card & mobile data, then clicking on SIM 1? Under preferred network type? Did you have it before the region change? Just thinking maybe you don't have a 5G enabled SIM.
[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
I have no idea. I'll check the quality when it comes, as long as the water seal looks good I think it should be ok. Pics from the website attached - looks decent enough.
[OPPO Find X2 Pro Guides, News, & Discussion] simonecapo:
I don't have a 5g sim but in the menu there is the possibility to deselect it.

I've tried 10 different dialers but the codes still don't work.
[OPPO Find X2 Pro Guides, News, & Discussion] ferchu91:
I know this is not the place. But has anyone tried this on find x2? Cph2023?
[OPPO Find X2 Pro Guides, News, & Discussion] Texan1:
Check my posts over the last few pages as I initially had the same issue. The thing that fixed it for me was deleting some network adaptors that appeared in the list in device manager (eg. some VPN programs create them).

Hope you get it to work.
[OPPO Find X2 Pro Guides, News, & Discussion] anasmhds:
Same comments for my CPH2025 in UAE, after rebranding it to Singapore EX. also not willing to change to MultiLingual EX or any other region.

I ordered dual SIM tray from AMAZON and will update you soon.:cool:
[OPPO Find X2 Pro Guides, News, & Discussion] hunhool:
I've ordered 2(1 gold and 1 black) but couldn't fit into the hole. What I have discovered, the rubber is slightly thicker than the original one ,and that prevented to push into it completely.

I managed to change region to Singapore EX but I could not update Pakistan. . 45 over Europe. 46. Is It even possible to downgrade from 46 to 45?
[OPPO Find X2 Pro Guides, News, & Discussion] kevinireland11:
Well I was able to do it, it's not a downgrade it's the same version only lower number, it let me go from A.46 to A.45
[OPPO Find X2 Pro Guides, News, & Discussion] kiko_san:
EU A46 to PU A45 can be downgraded
[OPPO Find X2 Pro Guides, News, & Discussion] mmeidl78:
Worked like a charme. Changed the region on my .45 and checked the Updates. Android 11 was shown and installed it. After the reastart C06 was shown and I upgraded it.

Right now I left the region to singapure cause even 5G works here in germany with t-mobile.
[OPPO Find X2 Pro Guides, News, & Discussion] belloni:
I have the option but it doesn't seem to be connecting to 5G. I definitely have a 5G sim as i had it before this region change. Might try a factory reset later today, will report back.
[OPPO Find X2 Pro Guides, News, & Discussion] kevinireland11:
Anyone having issues adding there card to Google pay after region change?
[OPPO Find X2 Pro Guides, News, & Discussion] Craphead:
It's not really a downgrade, the version is basically the same despite a different number, just like for example the German .46 and the German .45 VODAFONE variant are also the same.
[OPPO Find X2 Pro Guides, News, & Discussion] Pkmtre:
I finally was able to update EU. 46 to Pakistan . 45. I tried several times dowload-update process and now I am happy with Android 11. Thank you all?

[OPPO Find X2 Pro Guides, News, & Discussion] WeeTax:
Are you giving access on your phone? I didn't get an "OK" till I allowed the PC to access my phone. Hope this helps
[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
Oh, that doesn't look good. Maybe your phone is network locked, as in to a particular carrier. Slot of carriers don't bother locking there's days, but perhaps yours does.

There is a secret code you can dial to find ou but can't remember it. Can be accessed from the engineer menu, I think that's *#808#. If you do get in there though, be careful :)
[OPPO Find X2 Pro Guides, News, & Discussion] enginkpt:
Thank you ,As you said it says as I atteched in English also
[OPPO Find X2 Pro Guides, News, & Discussion] Texan1:
So as mentioned earlier, got the Android 11 update using the sec5 method and all went well, changed to Singapore, restart phone, A11 appeared as an update, flashed, OTA update to C06 then came through.

Couple things I noticed...

- now I just have a "Language" setting, where as before I could change Language and Region.

- now when I check for software updates it shows the full C06 update and changelog (which I already have) but no button to update obviously. Previously it would just say something along the lines of 'software already up to date'.

Is this the same for others?
[OPPO Find X2 Pro Guides, News, & Discussion] anasmhds:
Yes, I have the same
[OPPO Find X2 Pro Guides, News, & Discussion] backfromhome:
But then the question remains, is that due to playing around with the sec5 method or due to the Android 11 update?
[OPPO Find X2 Pro Guides, News, & Discussion] bartek45:
I think this is the way they present it in the new ColorOS. It lets you avoid clicking an extra button for the changeling, all the info is readily available from the moment you enter the update menu.

As to the region setting missing - in my case it was never there since I believe the a.30 update.

One more thing that I noticed has changed is the Ultra Vision Engine. I had it on by default previously and I could not notice it working in any app. Today I was watching YouTube and it seems to kick in - videos look like they're 60fps now. Same thing with MX Player playing videos from storage - there is a difference now. Haven't tested it yet with the likes of Netflix or Amazon Prime Video, but the update clearly seems to have done something to finally get it to work as advertised on my unit.
[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
It looks this way on my Chinese version too, it doesn't say "Up to date", just has the change log.

One thing that is concerning me now is that the Unlock tool doesn't seem to be working for me now. I see my serial number on the left, but no flashing OK when clicking unlock. Not massively bothered as happy with being on Singapore region, but wondering if Oppo have blocked something?

Is it still working for everyone else, and if so do the *#3954391# and *#391# codes still work to get you to the region change screen?

EDIT: The unlock bit still works fine on my Chinese variant....weird!
[OPPO Find X2 Pro Guides, News, & Discussion] dread123:
cant seem to get the ok message from the unlocking program... i get the device id -but seem to wait forever and no ok message? i have changed all the network settings and enable usb debugging and connecting in file transfer mode?? please help
[OPPO Find X2 Pro Guides, News, & Discussion] koloure2211:
I had same problem, I re-downloaded

[OPPO Find X2 Pro Guides, News, & Discussion] dread123:
Tried a different pc and still the same... Tried the unlocking tool and it shows in connecting via debug and mtp ?
[OPPO Find X2 Pro Guides, News, & Discussion] dread123:
Tried redownload.. Tried unlock tools.. Tried sec... Tried everything just get no ok?
[OPPO Find X2 Pro Guides, News, & Discussion] simonecapo:
Same mistake my mah, if I use Sec5 from ok, but then you can't give the codes, it doesn't accept them, example * # 06 # it doesn't give you IMEI.

In other words, you cannot change Region anymore.

[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
Mine is the same, I've changed region to Singapore EX, updated to ColorOS 11 and all working well, but codes don't work any nore e.g. *#800# used to get to the engineering mode. *#06# works for me though.

Not really a big deal as all is working well, just a little strange. I do have some issue with colour shift though, depending what's on screen. Keeps going yellowish.
[OPPO Find X2 Pro Guides, News, & Discussion] simonecapo:
If someone can help so as to avoid wasting time.

After entering former Europe as a region, some things didn't work and neither did the dialer for the codes.

I reset but the problem remains as the latest firmware.

Read the bottom part, once you in install it it won't appear right away reboot phone then keep swiping left on home screen and it will just appear out of no where lol
[OPPO Find X2 Pro Guides, News, & Discussion] Craphead:
Yes it's being recognized by the AV but not as malware but as potentially unwanted, and there's a big difference in that. It's like when you use a crack for a computer game, those also are always being recognized by the AV because they work in similar ways as actual malware but that doesn't automatically make it malicious in a way that is going to do stuff in the background that you don't know about...

[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
This is weird, but the sec tool doesn't work for me any longer either, it did though after updating as I tried Europe EX (Dual SIM) for about a day and then realised I wasn't getting a 5G option, so went back to Singapore EX. Was going to see if the Multilingual EX offered anything else but don't get the OK to appear.

Weirdly though, it does work on my Chinese version (which has ColorOS 11 too). Perhaps there is a limit to how many times the region can be changed, or perhaps within a certain time period from changing the first time....who knows. We might have triggered a switch to lock us out.

But my guess is this will work for people doing it the first time (assuming they follow the steps and don't have Ethernet issues), but probably stopped working for people who have changed.

Can anyone who changed their region more than a few days ago still unlock with the sec tool? And if so, how many regions did you try?
[OPPO Find X2 Pro Guides, News, & Discussion] simonecapo:
I changed EUROPE 1 time and got back there after 5 minutes.

Nothing ok and no codes.

Monday I deliver it to the service center.
[OPPO Find X2 Pro Guides, News, & Discussion] dread123:
I've not managed to switch once..so it's not a lockout down to the amount of times changed?

Updated to Android 11 a few days ago using the sec5 method.

When I go into Settings and then click on 'Home Screen, Lock Screen and Always On Display', I'm asked which app do I want to use and have a choice between 'Live Wallpaper Selector' twice.

Depending on which one I choose, I'm presented with two slightly different settings screens/options!

Anyone else get this or know why and how to fix??

[OPPO Find X2 Pro Guides, News, & Discussion] klanbo78:
Even if you could install on your phone, which is unlikely if you have a newer version installed (,e.g A42, A46), the quota for the beta was 5000 and that got filled months ago, plus the stable version has rolled out in those regions so the beta is probably closed by now.

Also, ColorOS 11 will be rolling out in Europe in the next few weeks (apparantly) so what's the point in fiddling at this late stage? :confused:
