Failed firmware upgrade - am I bricked?
I was foolish and updated my ReadyNAS 2120 unit from firmware 6.2.x to 6.9.4 without reading the readme (just assumed there'd be safety checks in there by default).
Now I know I was supposed to up...
Hi,
I have this same problem now.
Did you solve it?
At the end I have Trying UART
I have not yet fixed this problem but I haven't really had time to deal with it.
I ordered a 360 nand clip to try and make an image of the nand so I could try to reflash the bootloader onto it.
I was going to try this https://www.raspberrypi.org/forums/viewtopic.php?t=16775
If you have any luck, let me know.
Hi kbo123,
I have the exact same problem with my RN2120, and the warranty has expired. I guess the solution to my problem is to follow what you did... I am going to connect to the RS232 serial port but I expect to have the same problem as you had.
Did you manage to reflash a bootloader with your 360 NAND clip ?
Thanks in advance ! Regards.

Cedric,
I haven't had the time to really dig into this problem. There is a lot of information about this sort of thing out there though. You might need to dig and piece things together. They use an ARM processor with a U-Boot bootloader on the NAND. My approach was going to be to try and capture a dump of the nand as it is. Then I could try to construct/repair a new image to flash back on to the nand with the 360 clip. I did buy one, but haven't tried working with it yet. Raspberry Pi or arduino should be able to interface with the chip to extract the contents. https://www.raspberrypi.org/forums/viewtopic.php?t=16775
Hi, it is a waste of time and resources from my point of view.
First of all; it is not a problem with FW upgrade, but with damaged NAND. During a reboot, it will fail :( That was my problem.
I was resoldering RAM, but without any result, I was expecting damaged RAM at the beginning.
Copy content from another NAND and resolder it seems to be tricky. On AliE you can find such NAND memory, but you need a device to read/write content. (hardware and software). To be onest, I am not sure if NAND from AliE is working at all, I expect that it is fake. So the best way would be to solder a socket for NAND and take it from a good NAS.
From my point of view, it is much cheaper to bay on eBay and other portals similar used NAS.
The 360 clip should be able to attach right to the NAND without any soldering.
If your NAND is indeed bad, then yes the only way to repair is to solder new NAND or try to find a scrap system on ebay that still functions.
Personally i wouldn't bother trying to resolder the NAND because those pins are so close together.
