When i am come back home. I will try.
I have also order a New sim

I have same issue since latest carrier services update. Can barely make a call since yesterday.

Sounds like the update disabled VoLTE. Check *#*#4636#*#* Phone Information section and look to see if VoLTE provisioned is toggle to the left (off). If so, it sounds like a carrier profile update broke it. You may have to go back to old firmware.

Thx u i will check When i come back home.
I hope your right.
But i sûre update suck because troubles come after.
It s difficult to Come-back Old firmware ?

On all Google Pixels, you can downgrade to any firmware you like as long as you accept that you'll have to wipe the phone. The only exception to this rule was when the Pixel 6 Pro was updated to Android 13 Stable since the old firmware's bootloader had a big exploit.

June 20, 2023 TQ3A.230605.012.A1 Verizon/MVNOs / June 13, 2023 TQ3A.230605.012 Global - Unlock bootloader / Root Pixel 7 Pro [Cheetah] / SafetyNet
Pixel 7 Pro [Cheetah] Updated May 13, 2023 Note that more than three users have said that 34.0.1 (even May 10, 2023's binary update of 34.0.1) did not work correctly for them. I recommend sticking with 33.0.3 (just below these quotes) Someone...
forum.xda-developers.com
Either my instructions there or Official Google Android Flash Tool (OEM Unlocking needs to be toggled on - you do not have to manually unlock the bootloader - their site will do that on its own). You're welcome!

I Really appreciate. Thank you.

I have the same problems and more in Romania, on Vodafone. I think the modem is completely broken.
You shouldn't have to downgrade or root to fix any kind of problem. How Google can release crap like this is beyond my understanding.

I had the exact same problem, I asked RMA because it was impossible to call someone.first they refuse saying to me that an update will solve the problem but I insist and now with the other phone no more problem.i think there is a batch with broken modem

Can you provide the next update log? Thank you!
probably something to do with your apartheid state
you probably have a phone sold by a carrier, they get updates slower.
If you're AA you get 9.5.4, TMobile in the us gets 9.5.6, apparently AA gets 9.5.6 for the Verizon fix. EU people get 9.5.5. all of them receive camera update and I think April security patch.

use a VPN route to US and try again.
or use the oxygen app updater (if it even has the firmware)
otherwise VPN will work.

VPN to US? I live in Texas. Why do I need a VPN? So you really think something is wrong with my phone? Maybe because I RMAed it (my wife didn't want it, but I decided to keep it after I had already started a return)?
Oh... I need to VPN to UK? What? lol
Do I have to be off WiFi? I am like always on wifi, but I have turned it off and tried (TMobile SIM, but phone is unlocked from OnePlus)
UPDATE!!! You can now download it here: https://support.oneplus.com/app/answers/detail/a_id/4312
Downloaded file, moved the file up one directory from downloads to root, did local update. I just got done rebooting and all looks good. Time to take some photos.

If you're not getting it means that OP is rolling out slowly
They don't roll out updates all at once, they do it in batches incase there are issues and need to pull the update back

phone sim locked tmobile sim will not work

so i flashed to international rom then updated to android 10 and when i put in any tmobile sim card it says
Network Lock: This device can be remotely unlocked if eligible.
Please use the "Unlock" application to unlock the device.
Make sure the device has an internet connectivity to use the "Device Unlock application".
there is no unlock app on the android 10 open beta, im rolling back to android 9 to see if it fixes issue...
Rolling back does fix this issue but I am not sure why the issue exists in the first place. I did this yesterday - had the same problem and I used the rollback and phone was fine again.

Hey forgot to update the thread, yes you are correct. Just rolled back. Really sucks because Android 10 is a really big difference to me. I just sold my pixel 3xl and I'm already used to it. I'll probably give it another try when there's an update.

Android 11 for x2 Pro is out

https://cntechpost.com/2020/06/22/oppo-releases-coloros-based-on-android-11-beta-1/
*** It wipes all your data. So do backup.
It has Color OS 7.2 and still has GMS.
Download the zip and update in recovery. MAY BE BUGGY.
If you are in Beta, you may not be able to receive beta even when you rollback to 10

My model is CPH2025EU and their file is for the 2025PU... How can i fix that ? :-/
Oh dear, looks like this beta might not be worth trying yet.
But... well done to Oppo on offering it and to those of you willing to flash it.

The one who can find the solution must be "OPPO" themselves. Since nothing can be done with our device. No MSMDownloadTool nor OPPOdownloadtool (for consumer like us). Nothing can be done here. Guess they have a problem signing their package in the Kernel section.
Mine is Thai version. Dual SIM, CPH2025.
I tried to warn people in the comment section of ColorOS but sadly, I can't comment since my OPPO ID hasn't participated anything in their forum yet. So, I will let it go.
What about flashing a firmware through ADB ?
SIM card will no longer be read when you roll back in China version. The only solution is to install Android 11 Beta 1 again. I can now read the SIM card.
By the way, some people in the ColorOS community in China have similar symptoms.
Well in Beta 11, the phone detect my Sim Card, but i have no date mobile showing up even though i have my Operator setup appearing for MMS and 4G Data... Soits still a little problem.. i'm gonna flash Android Beta 11 then and hope for a second beta for Global version very soon...
EDIT : Beta 11 is really unusable ! The screen goes black and light up like crazy, multiples reboots, the phone gets warm as hell.... So no other choice than roll back to android Q, even if it means that i';ll not able tu use my Sim Card.... I can understand that a Beta may be buggy, but for this one, they really messed up !!
no sim card too

I think we need to contact Oppo to ask them to release a rollback firmware specifically for others variants, but i'm afraid they'll tell us that they warn us that Beta 11 was just for the Cbinese model...

Google Pixel 3 noobie queries

Hi!
I come from the Galaxy S series (S4, S5, S7) phones and I m considering of buying a Google Pixel 3
I can find many decent options, all of which are carrier unlocked
My concern with the Pixel 3 is whether I ll be able to install Android vanilla (without any carrier-related bloatware)
For all of my Samsung's so far, I could easily pick the retail ROM (well not exactly 'vanilla'!) from sammobile and load it with Odin (without breaking the knox)
Can I do something similar in the Pixel 3 or are there any security mechanisms to prevent me? (I m talking about installing original ROM - not custom..)
Bonus question - does any of you know if the Pixel 3 from Verizon and US Cellular have branding [carrier logo(s)] on the device?
Thank you in advance!
Well, you will certainly avoid the Samsung bloatwear. I have a P3 from Google and got my son's P3 through T-mobile. It did not have any additional T-mobile bloat on it, but I don't know about the big V.

I can find it via Verizon and US Cellular - hopefully none of which have put logos on it..
I have one more - rather embarassing question: do you have to use a Google account in order to use the Pixel 3? For several other Android phones that I know of - it's optional. You can still skip this step and use the phone without having to tie the phone with Google. But can you do that on the P3?
Any more hints on that and my ROM-related queries would be really helpful! Thanks

Verizon branded Pixel 3s have locked bootloaders, which prevent rooting or custom ROMs (vanilla AOSP would be a custom ROM). According to the flashing instructions at https://developers.google.com/android/images, you also need to unlock the bootloader to flash a google factory image.
I'm not sure if you can skip the google account. If you really want to avoid google services, my recommendation would be to install LineageOS, with no gapps.

Hmm...if the 3s has that, then the 3 will also have it :/
But I m confused...would I be able to unlock the bootloader?
I can see from this page: https://developers.google.com/android/images#blueline that 'blueline' is that vanilla AOSP version that corresponds to the P3 (right?)
The G account issue is less important. I just don't like 'syncing' stuff (accounts, photos etc). Worse case scenario, I ll create an empty profile, just for the logon

3s is not a model, it is the plural of 3. A Verizon Pixel 3 usually cannot be boot loader unlocked, but if you search this forum, you will find a few special cases where it has been done. One such case is at https://forum.xda-developers.com/t/...branded-pixel-3-how-is-this-possible.4267273/
Vanilla AOSP generall refers to a ROM without any google services. See https://android.stackexchange.com/questions/53171/what-exactly-is-in-aosp for more info. Blueline is the Pixel 3 factory image, which has all the google services. It does not have any added carrier bloatware, but I wouldn't call it a vanilla AOSP.
You can turn off all the syncing stuff, and you may be able to skip the google account part. I just can't definitely say you can skip the google account because I have not tried it.
Another consideration with a locked bootloader is the end support date. Google support for the Pixel 3 ends in October, 4 months from now. There will be no security updates from Google after October. If you have an unlocked bootloader, you can switch to LineageOS and continue to receive security updates. That is what I plan to do.

Clear!
I ll check on the resources you ve listed here
If the V-branded P3 is troublesome as it sounds, perhaps I should just go for the US Cellular carrier option. Bootloader may also be locked (but we know for sure that the V is..)
Interestingly, the US Cellular P3 is unlocked to all GSM carriers except Verizon, Boost, Virgin Mobile and Sprint
Is the carrier lock specified in the bootloader?
Btw, thanks for all the help!

SIM (carrier) unlock and bootloader unlock are separate, and not related. I have no idea if US Cellular is bootloader unlocked. Google sold a global model, which is the bootloader unlocked version, and the one I have. The IMEI/MEID number of the global variant begins with 990012 (don't know how many digits are significant). If I was buying it, I'd ask the seller to confirm it was bootloader unlocked.
Glad I could help.

The two P3 options I m considering (Verizon + US Cellular), both are sealed in their original box. According to that post, if the P3 hasn't ever being turned on, which is probably then when bootloader becomes locked
So I wonder if there is a SIM that comes with the phone already and that I have to remove that prior booting the phone. Not sure what he means with "VZW SIM". Is it a different type of SIM e.g. an eSIM??
I know for fact that these phones are CDMA-locked and only GSM is unlocked (but that's what I need anyways)
Does anyone here have any experience from an US Cellular P3 - is the bootloader locked? (the retailer of the phone doesn't seem to know much on such details..)

VZW SIM is just a Verizon SIM. It is probably the standard SIM card, not an eSIM. I would remove the SIM prior to booting, just to be safe. According to one of those posts, WiFi had to be connected before they could unlock the bootloader.

I ll find out soon, I ve ordered the P3 (US cellular stock)
Seller claims that it is sealed in original box. If that's really the case, then the carrier can't have put a SIM into it, right? But what about an eSIM? If they have the eSIM pre-programmed, then I can't possibly avoid booting the phone with it..

Hmmm I think the way it works is that when the phone is produced, for a specific carrier, and the carrier wants it to have a sim, it's put in at the factory. So, I think, sealed with a sim in it, possible.
I don't think us cellular uses e-sims. Double check that but it doesn't look like one of the carriers that's capable of e-sims.
cheers, good luck. I have a vzw coming today, hoping it's new and can unlock as others have... we'll know soon.
Good news! Just got the phone and ... I ve managed to unlock the bootloader!
Exactly same case as described here. No SIM inserted, connected to WIFI, and in Dev Options, turned OEM unlocking to ON!
Then, on the instructions (link by opensense), I ve used adb and the bootloader is now unlocked! I m really chuffed about it
(btw the US Cellular supplied SIM was attached on the box (outside) with a sticker. Box was sealed.
Now, all is left is for me to pick that 'cleaner' Android option I always wanted!
But which one should it be? It's currently running blueline MP1.0(ROW)
Is there any clearer (official) Android ROM that I should switch to instead?
From G services, I would like to keep the Playstore and Maps...

Congratulations. You'll have to define what you mean by the term "cleaner (official)" ROM. Blueline is the only official Google ROM for the Pixel 3. Anything else will be a custom ROM. I have no experience with any of the Pixel custom ROMs, so can't offer any advice on those.
You can disable most of the unwanted Google services in the blueline ROM. I'd recommend keeping the backup service, though.
Blueline MP1.0(ROW) is not a version listed at https://developers.google.com/android/images#blueline Go to Settings, About Phone, and tap Android Version. Check the "Android security update" date. Latest is June 5, 2021. I suspect yours is quite old.
If you want to update to the current blueline version, you have 2 options, OTA or flash a new factory image.
For OTA, go to Settings, System, System update, and follow instructions.
To flash a new factory image, follow the instructions at the link above. To prevent wiping your data when flashing, edit the flash-all.bat or flash-all.sh file, and remove the "-w" from the last line.
I you intend to change ROM's, I wouldn't bother updating.
Good luck.

I think I ll probably stick with the official one then. My current is PQ1A.181105.017.A1 (which is very old as you guessed)
Which means I can jump to Android 10 or 11. From my experience, latest isn't always the best so I might have to keep reading, see if I should jump to a latest build of 10 instead. My emphasis is on stability/security - not new features...
And I want to ensure that the camera is at its best

And I want to ensure that the camera is at its best

If security is a concern, you'll want to go to Android 11. 10 has not been updated since August 2020, when Android 11 came out. Also, I believe there have been camera improvements since August 2020, which would not be in the latest Android 10 build.
I have not seen any reports of stability problems with the June 2021 Android 11 update, which has the latest security patches.
I don't know if you can do an OTA update to Android 11 from Android 9. You might have to go from 9 to 10 to 11. You can flash the Android 11 image without going to 10 first.
I intend to do via flashing (whichever version I decide in the end). Not a fan of OTA

Question Changing from Global Rom to EU solved(ish)

Hi guys,
So I got the chinese variant of the OnePlus 9 - LE2110. It came with a global Rom already installed. I'm currently on os 11.2.2.2 LE25DA.
I've been reading through the forums and I'm not sure what I need to download exactly to get this over to EU Rom. I think I also saw that I need to let this update first as it's prompting me to install 11.2.7.7. Things are changing so fast with this phone in terms of recent otas and root options that I'm concerned I'll use a dated method that could brick my phone.
Does someone know what file I need to flash on this and how? Also should I upgrade first. At the moment I'm downloading a zip of this but I'm not sure if this is correct :
11.2.6.6
OnePlus9Oxygen_22.E.09_GLO_0090_2105252341
Thanks in advance for any help or pointers

Achieved it - as another user posted in another post. Set your device to EU before you update in the oxygen updater app.
But what was not mentioned is If you are just setting up, you also need to allow advanced settings in the updater. Otherwise I was getting a warning message telling me I have selected the wrong device.
Just updated using the updater with the device set to EU and I have BA version
Hey! I'm in the same spot as you were, but I updated it to 11.2.7.7.LE25DA. I also have the CN version. Do I have to wait to the next update to move from global to EU, or is there any option to change it now?
Thanks!

That was my understanding. However I've been having reception issues that I did not have with a CN huaweii I had before this phone so I'm thinking it might be the EU rom I flashed, which would be odd as I'm in Ireland.
,
Anyway, even though I changed my phone from oneplus 9 (eu) to just oneplus 9 in the updater, I am prompted to download 11.2.7.7 - even though that's what I'm currently on.
Anyone know if this is just the global version of 11.2.7.7? This would mean I would not have to wait for the next update though.

Regarding the reception issues, bugs are always possible, or maybe the antenna isn't as strong as your previous phone. From https://www.kimovil.com/ I can see that your Chinese variant should be perfectly fine in Ireland. I would recommend that you reach out to oneplus support, what you've done so far is not breaching warranty restrictions.
Otherwise the "nuclear option" is to use an msm tool to reset your device, including the "modem" (or EFS?) partition which controls certain hardware-related functionality. This is because I'm quite certain they don't change when flashing any of the standard update images (not even a "full" update). Not sure an msm tool is available for your Chinese hardware variant. This is also becoming more risky and not sure how desperate you are.

You said yourself that you're running EU version but have set the app to check for "global", so I'm a bit confused by your confusion. If you want to stay on eu branch, then tell the app that your device is eu.

Cheers, thanks for all that info. I may just live with it, I don't think it's bad enough to warrant messing around with MSM tools. The reception issues seems to only happen when I'm travelling across the county and probably switching towers.
Sorry if my post is a little confusing. What I'm trying to say is I'm having reception issues while on EU rom. So I thought if I change back to global rom this might fix the reception issue. I thought I could only do this if there was an update available. I changed my phone to global on the update and it says there is an update available even though it's the same software version, that's all.
Do you think changing back to Global could fix it?

I see, I highly doubt it, but it's a low-risk experiment and only a bit of fuss waiting for the download and update, so probably worth a shot. Not to mention the fuss to come back to eu version if it didn't help.
And to be clear about the app, I guess the app was then just telling you about the latest relevant image matching your preference, the "advanced mode" should probably be turned off once you've settled on the region of choice. It's only giving you persistent notifications, so it's not helpful and also quite distracting in the long term.

thanks, and yes regarding the app, I thought it was prompting me to install the same version of the software but for the global variant, this is not the case if you try it locally. I saw an option to flash it via the root method but this required twrp. Trying to install twrp at the moment but having an issue with the boot twrp.img command. anyway, if there's an easier way any pointers would be great but thanks for your help.
I'm also thinking if my connection issue persists I will get in touch with oneplus like you said - this is not an issue I should be having with this caliber of a phone.
If I get the global rom on, and make the same journey to test it, I will circle back here to let you know how I got on.
Cheers
What are the differences between the global and EU roms? Are there any benefits to using one over the other?

Not a lot, if any. On DA I'm getting the odd one plus notification from the updater or cloud services that I didn't get from EU. Otherwise it's the same rom. I'm testing the different variants to see if it makes any difference to signal strength (which it doesn't by the way).
I'm likely to revert back to EU rom because they say updates are quicker for it and 'should' be better in terms of gdpr issues. But they're basically the same (from what I can see).
So, just to be sure. Now that 11.2.8.8 has been released, I have to switch my phone in Oxygen Updater to EU version and full update? That's it?
