After not being able to use the dual sim card successfully, I downgraded vendor.img and rom to 8.1 but then realized that the lack of dual sim card on Pie was still better on 9.0.

After flashing the 9.0 vendor.img and rom back to 9.0, I keep getting a "SIM Network PIN blocked. Enter SIM network PUK." I'm getting this for both of my sim cards...Is this a common issue? Is there remedy? I tried re-installing with and without OEM fix, but still the same issue.

edit:

nope rebooted a few times. shut the screen off too. added biometrics and still no issue... the search continues

edit 2:

[MENTION=4499005]gubbilo144[/MENTION] well i think it is expanded notifications. i didint have any so it didint cause the issue. rebooted and sure enough i had a notification come in and it did cause the issue!

Dr. K

I'm running O7 and it's working perfectly.

I just have one question - is there a way to initially log on with biometrics (after reboot) and still have apps like PayPal and Dropbox and banking unlock with finger print after or is it 100% necessary to do the initial log on with the non biometric security method (in my case pattern).

Other than this one small thing your rom is perfect. The instructions were excellent and I had zero issues flashing it on 2 phones.

I'm waiting until you do further development for pie before upgrading.

Also your pro tools are excellent.

This is my first ever post on xda (been a reader for ever) - hopefully I didn't break any rules.

Thanks for the assistance.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] dr.ketan:
Amazing that you wrote first post after long 8 yrs to say this!

Yes, it is absolutely necessary else I may haven't put notice. If I find the way same like you said, of course it will be implemented.

Development on Pie with P02 will be much closure with earlier Oreo built.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Kcginc:
Thanks for the quick reply.

I was thinking about going to PEI but I use so many of your tweaks in regular and pro I'm not ready to give them up.

I'm in no rush.

Thanks for all the great work you do.

I personally really appreciate it and I always make sure to follow your instructions. They are extremely clear.

Thanks again.

I actually have one more question. The Google smart lock works fine when connected to a Bluetooth device or with on body detection but for keeping phone unlocked in a location it's not very reliable at all. Is there a tweak or something that I can apply to fix this.

I googled it and tried a lot of different solutions but they mainly work once or twice then fail. This request isn't for me it's for my GF because she doesn't use Bluetooth but she'd like to keep her phone unlocked while at home with the smart lock by Google.

It's not a big deal at all but figured it couldn't hurt to ask.

Thanks again.

[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Kcginc:
Solved (Maybe)

I think that installing the google find my phone app solves this problem - since it's a Samsung Phone I normally just use the Samsung find my phone but if anyone else is having this problem this is worth a shot.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] €nix:
Ups, sorry, you are right -> "Currently on stock 8.1". In this case you don't need to flash vendor.img and just follow instructions from dr. Ketan.

in a few words

wipe

if not already rooted -> flash twrp per Odin

Flash Modem BL and CP (Odin)

Flash latest Oreo

After installation don't forget to execute bluetooth fix from Rom Tool N9. Without this fix all paired bluetooth devices will be deleted after each reboot. Very bad.

that's it.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] lightdelegate:
Ok so first exercise I do with pie.

Same error I had (before flashing vendor) on oreo started on pie again.

After watching YouTube and using the Bluetooth headphones (iconx2018) then somehow internet get blocked by the phone.

All otger phones or laptops are getting internet.

The solution is to reboot or go into flight mode and out. Internet comes back.

I really don't know what to do.

Just driving me crazy again.

Thanks, I am rooted with TWRP and since my current version of stock coincides with V08 (build N960FXXS2ARK3 Nov Security patch) I don't think I need to flash modem BL and CP (Odin), correct?

My problem on Oreo was with call records missing record button (i recording not all calls).

My solution was to disable Rich Communications (RCS). Of course call record has to be before enabled in cscfeature.xml manuel or with Doc Tool Pro version. This should disable RCS-Camera button on active call and record button is on left side.

I think this is layout/place problem for both option, RCS and CR, and not solution for your problem but you can try it if you want.

How to disable Rich Communications

Go to Chat settings

Choose RCS settings

Un-tick RCS

[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] bober10113:
At least files are there. Then I don't think that is your issue. You can try putting em both to EGY or vice versa both at XEU. It's important that you retain file permissions after modifying them. So note each file's permission before hand. But anyways don't think changing any of the region codes will do anything. Really seems as it's a modem/version issue though.

Anyways might as well try it. You can back up efs and carrier configs(odm) partitions in Twrp to revert back what ever you edit in these 2 files.
