[LG V10 Themes and Apps] AnonVendetta:
JSYK, I no longer support this anymore, and there will be no more updates.

I can use Galaxy Apps Store on my tablet and phone, but they are both Samsung, so I don't usually need to change my device model on custom ROMs, the store works by just installing the app normally (not into system partition). If your device isn't Samsung, then you may need to change the model. Try just installing the store apk and see if it just works as is. Although you may get an incompatible/unsupported error.

If that happens, spoofing or changing the model will be necessary. I tried XInstaller earlier today, on an Android 13 custom ROM, it appears to have no effects on model changing. So I suggest not trying it. The app is old and will most likely only work properly on older Android versions.

But you still have options.

1. Systemlessly change/spoof the model with Magisk and/or LSPosed

2. Change the model by editing it directly in build.prop

For the systemless option, I think the only app that will help is Android Faker, it requires Magisk AND LSPosed. And changing the model is a premium feature in the latest version of AF, so you would need to pay the app developer if you want to unlock that option.

Another systemless option is finding the right build.prop, editing it, then systemlessly overlaying the file into the correct location. This will leave the original build.prop file unchanged, and it will only be systemlessly replaced by the edited file. Reverting the model change is as easy as deleting a Magisk module and rebooting. However, I don't know much about the specifics of systemlessly replacing files with Magisk, so you may want to ask elsewhere for info on that.

Last option, edit the file directly, which still requires root access. This will be a direct edit rather than systemless, so you will need to back up the original file before editing. Just in case something goes wrong. Direct editing may not be possible if your system/vendor partition is read only and unable to be remounted as read/write, so you will have to fall back to systemless methods if this is the case.

Go to /system/build.prop, open it, search for "model". If not found, try opening /vendor/build.prop, search for " model" again. In the vendor partition build.prop file, you will probably find that search term. Basically, what you want to do is change it to the model of a real Samsung device, like SM-N986N or SM-T976N.

I would suggest the following edits:

ro.product.model=SM-N986N

ro.product.vendor.model=SM-N986N

Be aware that changing these values could have unintended side effects, although I've never personally encountered any. So if something bad happens, you may need to undo the change.

You can go to apkmirror.com and find a Galaxy Store apk there. Don't worry about the other system apps I mentioned in first post, and don't use any zip files in this thread that I've posted. If you can get the store to launch, I also suggest installing Samsung Internet browser and setting it as default web browser, if you have trouble logging into Samsung account in the store.

I'll end this post by saying that I don't really think using Galaxy Store is worth the effort anymore, unless you have a real Samsung device that's running stock firmware. Most of the apps in the Galaxy Store can be found elsewhere.
