• Ensure you have US/EU model 3590 with HWID 1258: [Only registered and activated users can see links. ]
• Ensure your US/EU 3590 has latest firmware Version 8.50 (connect to GarminExpress and update if it has a lower version)
• EXTRACT the Flash Kit ZIP file directly to a CLEAN microSD card (look behind Spoiler below)
• Ensure your device is fully OFF, not just in standby mode
• Insert the card
• Power on (if the battery is low, connect to an external power source [NOT a computer USB port] which will power it on)
• "Loader"/"Software Loading" or similar message should appear on screen during start-up
• Wait for it to finish the flash and re-boot itself, then remove the card.

Spoiler: Flash Kit

"Apps" screen should now have Media Player and Video Player icons. Keep the files from the card in a safe place. In the card root you should now additionally have '41_BUP.bin' and '140_BUP.bin'which are copies of your device's non-vol and features regions. In the 1258 folder there will also be a new file named 'last_id.bin' which must be removed before re-using the files or it will prevent further flashings.

Most links are still down, so I have some quesions.
My unit Nuvi 2455LMT. B1371-00 8.30 PCB105-01925-02 TZMap 37.00
1 Does this still work in 2024,almost 2025?
2.After these changes will garmin still update fw and maps without any problem?
3.Where can I find the original firmware for this unit?
4. Mainly I'd like the asr to work, will the asr files and xml download to the unit after updating?
Thank you very much
