I just finished the jump from 18.1 to 20. I wasn't able to update the recovery (fastboot couldn't see my device), but other than that everything is working as well as I can tell. VoLTE is disabled in my settings, but calls/data are working fine.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] xdabushrang3r:
Calls and data working fine for me too. I still need to patch the new recovery with Magisk and install, but other than that, all seems to be working.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] dor_pauli:
Isn't recovery included in the installation zip file? I jump from 18 to 19 some months ago without any thoughts of recovery and it is on the latest build for 19.1. Beside that the boot image and not recovery should be patched with magisk. 🤔
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] xdabushrang3r:
Oops, yes, that's what I meant to say. Patch the boot.img with Magisk.

I rceently updated from LOS 19 to LOS 20. Everything working perfectly.

One odd issue though, in both OSes I cannot send sms, tried several apps just in case.

On the other hand, is it possible to update firmware now that oneplus released F18?

It's recommended to use LOS recovery with LOS roms.

[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] DasGundi:
Installing of LOS worked perfectly along with MindTheGApps. But i cant get a Play Protect Certificate. I tried it with the adb command from the Register-Site from Google but all i get is the error "inaccessible or not found". Has anyone had this problem too and knows a fix?View attachment 5968261

Running on LOS 20, MindTheGApps and used the SafetyNet-Bypass in Magisk.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] DasGundi:
Fixed it by reinstalling LOS, installed MinedTheGApps and directly install the ih8sn and no magisk

Thank you very much for your work on this tool! Works nicely on my OP7T with LineageOS 20. I see that you mention also OP5 which I will be testing some time as well. But I was wondering whether this is somewhere a centrally maintained thread or website on this tool? Could be useful as pretty hard to gather bits and pieces spread over all the different forums and threads.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Eric_Lev:
About ih8sn:

@LuK1337 and several LineageOS developers are the creators of ih8sn.

==> You can find their work on ih8sn at: https://github.com/luk1337/ih8sn

@althafvly plays a significant role in maintaining and enhancing this tool, making them one of the most active developers.

==> His contribution to ih8sn can be found here: https://github.com/althafvly/ih8sn

For more information about ih8sn, there is a comprehensive XDA post available:

==> Check out this XDA post on how to bypass SafetyNet on Android using ih8sn: https://www.xda-developers.com/how-to-pass-safetynet-android/ ... (Part 5)

As far as I am aware, there isn't a dedicated discussion thread for general conversations about ih8sn.

For clarification, I'm not an Android developer myself. My involvement mainly revolves around editing the configuration file (ih8sn.conf) for my devices and sharing the results.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
Thank you very much for taking the time to enlighten me! One more question for now: I saw a bunch of device specific on your Sourceforge files. You list in your earlier post also some devices where there is no device specific file. Am I right to assume these devices are covered by 'ih8sn-aarch64-All-OnePlus.zip'?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Eric_Lev:
Not all OnePlus devices are compatible, as firmware updates to OOS13 have sometimes broken ih8sn... This is the case with the OP9 and 9T... and I haven't had the time to fix the issue yet.

In my own usage, I opt for a customized configuration because the generic one can occasionally lead to problems with specific apps such as banking, social network or Netflix.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] js-xda:
OK, but it sounds like it could still function with an OP5 as no firmware updates anymore, right? (Sorry, somewhat off-topic but I will report outcome on the correct forum.)
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Eric_Lev:
Right.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] dimoochka:
Hi Eric! Having an issue with this out of nowhere. Basic passes, CTS doesn't. Do you happen to have an ih8sn config that works for the OnePlus 9? This is my current config:

Thanks LuK1337 .. Flashed to LineageOS 19.1 from Oxygen OS 11.0.9.1 HD65AA without prior upgrade to Oxygen OS 12.

The install went well, slow startup though during reboot or power off. Shows capacity for 2 SIM cards, which is good.

Model Shows HD1901 any difference from HD1905? Or should I say any difference from the India vs US varient?

Is there actually any downside of first going to LOS18 and then upgrade to LOS19 while skipping OOS12?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] LouMinartey:
Is the 48mp camera accessible from this ROM?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Syed Numan:
You don't even have to go to LOS 18 in the first place since LOS 19 is shipped with OOS12 firmware. So in short, if you are running OOS 11, you can directly flash LOS 19 without updating your Oxygen base to 12. Also do note that in case you like to go back to OOS, the only way to do so is using MSM tool.
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Fap4k:
Have two questions

1. As you said this rom shipped with OOS 12 firmware so in that case we can flash this over any rom I mean I am on PE 12 right now so can I flash it??

2. If the answer for above question is yes, then I will have OOS12 firmware in my device so can I flash other roms which require OOS 12 firmware over LOS 19 without going back to stock?
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Fap4k:
Delete
[OnePlus 7T ROMs, Kernels, Recoveries, & Other Deve] Syed Numan:
1. You can flash it over PE 12.

2. Mostly yes. I'm still not sure though. Haven't tried but technically it should work if other rom is OOS 12 based.

Issue encountered.

1. Always on VPN (OpenVPN) will display error waiting for usable network. Have to switch to airplane mode and off before VPN connect.

2. Screen will turn black when standby, unable to turn it back on. Only way to resolve it is by call my HD1900 from another phone and accept the call to access the screen.

About bypassing Safetynet attestation without Magisk:

If you don’t want to rely on Magisk to pass SafetyNet attestation, use ih8sn !

1- This tool is mostly intended for people who don't want to use Magisk.

2- Credit to: @LuK1337 ... https://github.com/luk1337/ih8sn

3- Successfully tested on the following devices: OnePlus 3/3T, 5/5T, 6/6T, 7/7T, 8T and 9 on LOS 18.1, 19.1 and 20.0 !

Prerequisite:

1- Recommened: No root so No Magisk !

Installation :

1- Download ih8sn zip file (see here)

2- Boot to LOS recovery

3- Flash the zip file via Apply Update from ADB or USB OTG

4- Reboot system now

5- Optional: install Magisk

Note :

1- After the first reboot, do not forget to clear storage of Google Play service and Google Play Store apps ... then restart your device ... in order to get Play Protect certification.

2- Re-flash ih8sn zip file to uninstall.

3- The safetynet bypass is preserved after updating the build via OTA so no need to reflash ih8sn at each update.

4- The safetynet bypass is also preserved after updating the build via recovery on A-only devices so no need to reflash ih8sn at each update ... but it is not the case for A/B devices, you have to reflash the ih8sn zip file in sequence with MindTheGapps.

5- I use the release of @althafvly ... (Add support for removing ih8sn - https://github.com/sdm870/ih8sn)

I wiped my OnePlus 7T, installed LOS 19.1 2022/10/30, and it works great... until I plug in a SIM card. Then it just shuts down, reboots to recovery, and gives me a warning about possibly being corrupt. If I remove the SIM it boots up and runs perfectly again. I tried 3 different SIM cards; same behavior. I have never seen anything like this before.

Before I spend the rest of the day troubleshooting I figured I would ask here if anyone has seen this reported elsewhere and if there is a known fix?
