Hi Max and Greg,
I’m reaching because I have appreciated your youtube videos (good work with the site, by the way). I’m hoping one of you may be able to assist me. While in Mexico in February, my Note 9 fell into a bootloop. I didn’t attempt to flash anything, I was merely on the beach, not paying attention to the phone at all (maybe it tried to update- I have no idea).
I could factory reset the phone, but I don’t want to lose all the notes I’ve taken on Samsung notes app (and no, unfortunately that data wasn’t backed up anywhere).
This is a T-Mobile phone (I don’t believe it’s rooted)
I wiped the cashe
I’ve attempted Safe Mode… it just loops to restart
I’ve attempted to force an update through ADB via my PC. it shows that it will connect from CMD or a Powershell when I check “adb devices”, but when I attempt to sideload, after “opening update package” it reads:
“E: footer is wrong
E: signature verification failed
E: error: 21
Unable to open sysfs usb node (no such file or directory ). Trying configs
Failed to open configs node (Permission denied)
I also attempted to force the firmware update via SD card… also with no luck.
I believe android debugging is enabled
I don’t have a custom recovery installed and I haven’t attempted to flash CWM or TWRP, mainly because I’m not confident that I wouldn’t erase my data.
Apologies if I’m not including important info, I’m not well versed in this type of thing.
Thanks in advance for taking the time to read this…love the videos!
