If anyone still wants to use Reddit Sync there was a post up on the Reddit page for the Revanced patch. In case you might want to stick to Sync till the Lemmy app launches.
Here is the tutorial shared by the creator, u/KobeW50
I tried it and it worked. You can try it on Sync Pro if you have the apk.
I am pasting u/hihowareyou0_0's simple guide.
-Go to https://www.reddit.com/prefs/apps
Click on "Are you a developer? create an app..."
Give it any name.
Set it as "installed app."
IMPORTANT: Set " redirect uri " to http://redditsync/auth
create the app.
TAKE NOTE OF THE CLIENT SECRET (the gibberish text and numbers below the Name)
Go to any Text editor (I use an app called "just notes")
Copy + paste the client secret. (And nothing else.)
Save the file and call it " reddit_client_id_revanced.txt "
MAKE SURE TO NOT SAVE IT ON ANY Folder, JUST THE INTERNAL STORAGE/ROOT
Download (not install) this sync for reddit apk
Install & open Revanced Manager
Make sure all permissions are enabled (Especially " All files access ")
Go to the "settings" tab.
Enable "experimental patches support."
Restart revanced manager
Go to the "Patcher" tab.
Click on " Select an application. "
Then CLICK ON "Storage" and select the .apk we downloaded.
Click on "select a patch."
Select " Change Oauth Client ID" (and optionally "disable ads")
click on done.
Then finally click on "patch."
Now wait for it to patch and install the patched apk!
If it asks you to update, DON'T. (just a warning)
Yeah... I considered it. And then decided that not only was Reddit no longer worth the effort, but that I actively want to prevent them from using any of my content for their benefit, so I overwrote and deleted my entire comment history. Now I'm waiting a few days to see if they restore them, because apparently that's the level of bull that Reddit is now stooping to, and if I delete my account I won't be able to nuke my comments again.
But I fully understand why someone would be inclined to do all of that. I very nearly kept at it. In the end, I no longer trust them at all as a platform.
