Is there any possible way to get the old firmware of GL4?

catlipsx · 03-27-2024, 01:47 PM

I purchased a GL4 on eBay, and it arrived today in South Korea. While I was waiting for it to charge, it automatically updated its software. Unfortunately, due to this update, I am unable to download any other Android apps using ADB as I cannot enter USB debugging mode. I was wondering if there's an alternative method to downgrade the firmware version?

Sorry, but you cannot go backwards.

Go over to XDA. I think I saw your same post on Reddit, too. Someone responded to this but if that wasn't clear enough, just go over to XDA--there's threads talking about how to. Not hard at all, but you will be eventually updated again, so make sure are not on Wi-Fi while you're doing what you need to do.

Do you have any links for that post? I looked up at XDA and couldn't find it
