Why is my DS sometimes not waking from Sleep?

Hello friends!

I bought a Modded New Nintendo 2ds XL sometime in 2017 or 2018. Since then stopped using it for awhile formatted the micro SD that had come with it. Now I have recently picked it up again and was having issues with getting to boot properly. Turns out I needed to get all of the Luma Files,GM9 (GodMode9) back onto a new SD card. After that I was able to get it to boot properly again.

After that I was able play games for awhile but noticed that after playing some games that intermittently it would not wake from sleep! Now I have tried a few things to resolve this issue. Here's a breakdown of what I have tried.

• I have ensured that both boot.firm, boot.3dsx, and config files from the latest release of Luma are pasted to the root of the SD Card.
• Checked that boot.firm file has been updated in CTRNAND via GM9
• Updated GM9 to latest version from GitHub
• Used a new SD card and repeated steps from Above
• Forced a rebuild of exdata
• Re-seated battery a few times during this process

At this point I'm assuming that there is an issue with firmware corruption and will try a CTRTransfer before I start to assume that there is some weird faulty hardware.

My question to you fine folks is. What else is there left to try, did I miss anything while troubleshooting here? Does anyone have any idea what is going on and have run into any similar issues? I have went ahead and ordered a new battery as I am assuming that this one is worn and would need to be replaced at some point not that I am expecting this to fix the issue. If anyone has any suggestions please let me know and I will probably give it a try.

Thanks ahead of time to anyone willing to help!
