There is also an issue that affects Vodafone and Orange users (possibly other networks, but so far these two are the only ones known to have (had) issues). Their SIM cards appear to force a different update channel. If this is the problem you’re running into: Whilst they sort this out, the only other option that’s been reported on the Forum relies on having access to a SIM from a different provider: remove the Vodafone or Orange SIM, insert the other SIM (if it wasn’t in the other SIM slot already; note that removing all SIMs appears to be insufficient to reset the update channel), perform the update, and switch/put back the SIM(s).
