[Galaxy S6 Q&A, Help & Troubleshooting] Apotrox:
Let me tell you a story (you can skip if you want to):

Once upon a time I ****ed up the back layer of the touch screen during repair and desperately tried to use my phone with my PC, found some tools online that let me simulate my phone's screen via ADB. Didn't got that working, ADB was unable to recognize my phone. Ok. Then i taped together the touchscreen (one of the absurdest things i ever did), reconnected it to the phone and guess what. It worked. I booted into recovery mode first and it worked flawlessly. No issues whatsoever. "Wonderful" i thought to myself, booting into system mode eagerly. The boot animation went by without any crashes, graphical issues or anything one could think off, and i even was able to enter my pin. When i did that i was full of enthuisasm. But that didn't last long. The SystemUI began to crash constantly, the lockscreen hasn't even finished building and it crashed again. I was absolutely unable to use the device and utterly devasted. Then i absolutely knew: i. ****ed. up.

But that didn't keep my from trying things out and eventually i was able to get past the lockscreen (without a SIM card so no PIN required) without any crashes and back up at least Whatsapp and a few other apps. But then i made the mistake of turning the screen off which set me back to square one: constant SystemUI crashes. I tried again and again and again and finally, after hours of work i got in a second time. This time, i thought to myself, i gonna make things differently. I backed up everything with Titanium, thought of myself to be safe. Which i technically was, i got backups of everything now. Then i decided to re-flash the rom without a factory reset which didn't do anything. Luckily there is an unofficial build of the ROM i'm using (Resurrection Remix) and i clean flashed it. It worked. Flawlessly. I was thrilled. The phone i was ready to toss into the trash finally worked again. I set everything up, thought myself to be safe but boy was i wrong. Google made regular (i think daily) backups of my apps and contacts and all so i wanted to restore that first. But it required a Pattern which i don't have because i always had a 5x5 pattern and it gave me a 3x3 pattern. I didn't know what to do with it!

I continued setting up my phone after failing to restore that backup and then instantly continued to restore the backup i made with Titanium, It installed all the missing apps, apparently restored the data. Nice. But there are a few apps that don't like that restored data so they just didn't use it and started from scratch again (like SwiftKey). Also, some of my contacts are missing and i'm lowkey too lazy to like the existing ones to Whatsapp again.

Tl;dr: ****ed up phone, got it working again, some apps didn't accept the Titanium backup and now i want to restore the Google backup which requires a 3x3 pattern which i don't have because i always used a 5x5 pattern.

Well, the question is simply: Is there a way to unlock the Google Drive backup without that pattern or do i need to try my luck again accessing the old Data (made a TWRP backup before flashing the new ROM)? If i do need to try again, how do i disable the lock on my backups? Do i only need to change my pattern to a 3x3 one?
