AP621 bricked — both boot partitions corrupted, need AP621 firmware images (5.4.x and 5.5.x)

Hello,

I have an AP621 that has stopped booting. I verified via console that both boot partitions (primary and secondary) are corrupted, so the unit can't load runtime firmware from flash.

My RFS6000 controller does not have the AP621 image loaded (only newer AP models were ever provisioned on it), and I was unable to extract/copy any AP621 image from it.

Could someone please share the AP621 firmware image files for:

5.4.x (e.g. AP621-5.4.2.0-030R.img or similar 5.4.x build)
5.5.x (e.g. AP621-5.5.6.0-019R.img or similar 5.5.x build)

Any working AP621 .img build in this range would help me get it back on its feet via console/TFTP recovery.

Thanks a lot in advance!

Hi,

I'm happy to research this for you. What is your serial number and/or company name?

Thanks!
