I picked up one of the Roamio OTA with Lifetime Service off of Amazon the end of last week and I'm trying to complete a 4 TB upgrade using a WD Green WD40EURX (Mfg 16 DEC 2014) and not having any luck. Here's what I've done so far:
1) Called TIVO and had them activate the Roamio. It's showing up as Active with Lifetime service on their site.
2) About 24 hours later (had to wait for the 4 TB to be delivered) I just tried popping the 4 TB in with the hope the Roamio had 20.4.6 or later, but no dice, so went into an endless green screen boot loop.
3) Reinstalled the original 500 GB drive and worked through the guided setup to get the latest and greatest software. Tivo started up and worked fine.
4) Put the 4 TB back in, this time it was recognized and the firmware pushed onto it, eventually leading to guided setup. Powered down the TIVO, then hooked the 4 TB up to my PC and used the MFS Reformatter tool (v 126.96.36.199) to resize to the full 4 TB. Seemed to work successfully and had no errors.
5) Reinstalled the 4 TB in the TIVO, and started guided setup. During the "Getting Setup Info" phase the TIVO errors out during the verifying portion with a "S308
" Error Code, "Problem Verifying Info. Your device cannot complete Guided Setup. Please check your cable connection and try again."
6) Called TIVO support, they said the S308 is usually an account/device activation issue, but they don't support internal HD upgrades so I should put the original drive back in (which works).
7) Waited another 10 hours or so, put the 4 TB back in and tried again and still getting the S308.
8) Just for grins, put the 500 GB back in, did a system wipe/reset, ran through Guided setup again and it's now getting the S308...
Anyone have any ideas? I don't think this is some sort of timing issue related to activation because if that were the case I don't think the 500 GB original drive would have been able to complete guided setup. Plus it's been almost a day and a half since I first called TIVO and activated the Roamio.
