I have three Samsung handsets—Galaxy Note 8, Note 9, and Note 10+—all still on their original, un-rooted firmware. I simply want each of them running a stable Android 13 build. Here’s what I need from you: • Locate or build a proven Android 13 ROM that is fully compatible with each model (security patches, VoLTE, camera, S-Pen, and Samsung-specific features must remain functional). • Provide clear, step-by-step flashing instructions—or guide me live over a remote session—covering bootloader unlock (if required), custom recovery install, the actual ROM flash, and post-flash verification. • Include any rooting, Magisk, or recovery files only if they are essential for the upgrade; otherwise the devices should remain un-rooted after the process. • Offer a quick rollback plan in case something goes wrong. Acceptance criteria – All three phones boot into Android 13 without bootloops or major feature loss. – SafetyNet passes (or Google Play integrity checks) so banking and wallet apps still run. – I can replicate your steps later using the documentation you supply. If you have prior experience bringing older Samsung models up to the latest Android version—especially with Odin, TWRP, LineageOS, or One UI-based ports—let me know. I’m ready to start as soon as I find the right expert. I have already downloaded the roms for the Note 8 if that helps. We can do this remotely because I am good at following clear instructions.
