Google pay is not working for me, even with safetynetfix 2.2.1 installed and passing safetynet test.

"Phone doesn't meet security requirements."

Any help much appreciated.

Could be because the system is running in permissive mode ?

First of all, this is a Samsung s4 rom. Not a Poco one. Secondly this rom is actually tweaked for s4 in order to work better.

Thirdly, oxygen os? For jf?

I think u r confused a bit
Sir, i am sorry for disturbing you, i just want to know if the team has made the optimized lineage os 19.1 rom for s6 edge plus or will they be making any in future

Some progress. Google pay works if accessed from the task bar, but not if accessed from the app. Maybe that's a feature and not a bug 😉😉😉

Is it just me or does the YouTube app show a corrupted videoscreen when playing any video?

How do I fix this?
Some (probably old) screenshots about the ROM:

Anyone that has an other model than GT-I9505 but the model is compatible with this ROM:
Can you test my unofficial TWRP 3.6.2 build?
I would thank you!

    Doing nothing for a while has fixed my YouTube issues. Wish everything was so simple 🙃🙂🙂🙂
    Waiting only helps when opening YouTube in a browser. But the videos in the YouTube app itself stays corrupted for some reason
    ... unable to make outgoing phone calls or receive incoming calls ... Mobile Data work fine, but perhaps it doesn't recognize my sim card entirely? there's an exclamation point embedded within the cellular signal icon in the notification bar.
    my carrier is H2O Wireless (AT&T mvno)
    I've never heard of sim cards which only get recognized partly by a mobile phone. If mobile data works fine, your phone should be able to make and receive calls, too. I've read some time ago, that carriers switching from "classic" calls to VoLTE. Maybe that's with your carrier, too. Unfortunately, our old S4 doesn't support it at all.
    follow up to my post #234 above..
    ... carrier (H2O Wireless) and they said the S4 is no longer supported on their network (AT&T) since they've shut down their 3G network. they said the S4 "lacks the necessary 4G bands that AT&T requires".
    ... is this info they told me correct - the S4 lacks certain (or all) 4G bands? ...
    IIRC, that's not entirely true. Obviously I was right to assume your carrier switched to VoLTE. Until now I thought, VoLTE works with the existing 4G bands. But - of course - in any case your device has to support it. If you want to know more about it, you can just search for VoLTE. I'm quite sure, the internet is full of information about it.
    thx downloaded optimised 19

    usinng odin is .img.tar for twrp ok to use

    at present having laded pixel pye on 19505 twrp dissapeared it only boots to pixel, so far ive been unable to reload twrp even though it shes success withodin, any suggestions
    If you've got problems, you should (always) first check op if there are known problems / information about flashing etc. If you would have done it, you could have seen the reference to SAMSUNG GALAXY S4 UNIFIED GUIDES & COLLECTION 👨‍🏫 from @Retrial - a great collection of flashing (and troubleshooting) guides. I advise to check it out.
    important! if you wanna flash gapps on twrp 3.6.2-9, flash BiTGApps from here:


    this is the only compatible gapps that i heard flashing and working so far
