RN102 unresponsive after initiating FW update from 6.10.6 to 6.10.7
Initiating update from local admin page, everything seemed normal including the blinking power light during the update process. I received a status email that the unit was rebooting, and I watched...

Question about Marvell ARM chip:
Which one, exact part number please, does this unit use?
I would like to know if it is an SOC device with flash memory.

I am waiting for a reply on another post regarding testing the only thing
I haven't tested, the serial port.
If the serial port yields nothing, I am off in search of documentation.
FULL DISCLOSURE:
At some point while inspecting the insides of the failed unit I discovered
the battery was at 1.98V. I used a fixture to keep battery voltage applied
to the board while I replaced the battery. Even though the original battery
was in this poor condition during the OS update the RN102 was always on a UPS
and never lost power.

Not convinced that the cost of repair is worth what you'd get. We're talking about a 9 year old entry-level NAS. But if you want to give it a try, of course you can.

Netgear doesn't provide the hardware documentation you are looking for - and I don't work for them, and have no access to internal documentation.
Googling suggests it is an 88F6710. But it's probably best if you look at the system board and confirm this.
Few users have the equipment to de-solder and solder ball grid array parts. Many of the parts cannot be purchased in small quantities. And just figuring out what part(s) need to replaced is going to be quite a task without a schematic. The board most likely won't hold up to just replacing things until it's fixed.
Even Netgear doesn't repair them.
So, at least for most, it is a matter of capability, not will. If you have the appropriate equipment and skills needed, then go for it and please share whatever you learn with the forum.
Thanks for all the input!
Yeah, the time & resources I spend messing with the failed unit are just part of my hobby.
Some people like picture puzzles or crosswords. I like resurrecting broken machines.
Well folks, it's been fun. Guess we'll leave this issue unresolved.
The unit died using the online update, causes unknown.
(Makes me wonder if the manual update would have been successful.)
If I learn more I'll post it, of course.
