|FOTA Impractical at AT&T for Current Lumia 900 Issue |
<< [engineer] The software glitch is so bad that the phone cannot remain stable during over hte air updates. ... My understanding is that the glitch disables the data connection, and that for some, not even resetting the handset brings it back. If so, it is kind of tough to tell people that they need an over the air update. >>
Your understanding is correct. Some users receiving preordered phones shipped for arrival a day or so before Sunday's official launch and also some reviewers who received devices 10 to 12 days or so ago lost all (EDGE/HSPA/LTE) packet data connectivity on their mobile devices. Some could reset to solve the problem. Some couldn't. Some that were able to reset lost packet data connectivity again. Some did not.
The issue hit various support forums well before any store openings on Sunday. The 1st post to WPcentral Forums was recorded at ~6PM on Friday. Since then there were ~160 posts. The Nokia Support Discussions forum got its 1st post shortly after midnight on Sunday. Since then there were ~25 posts. Phone Arena was the 1st media publication I'm aware of to report the issue and they did so very early Monday morning. I clipped these from the media or various support forums on Monday ...
We had similar issues with our Nokia Lumia 900 review units, as did other reviewers like The Verge. As we understood the issue, it had to do with activating the review units on AT&T, and the issue wouldn't affect retail units. ..... There is a defect with the IMEI's registering to the data network on 2g, 3g and 4g data. AT&T and Nokia have quietly addressed and are removing stock of the defective devices. ... A fix is coming, and it will hopefully solve the problem in both review and retail units. ..... The problem reportedly happens when the Lumia 900 is powered down, restarted, or put in airplane mode. Indeed, we saw the issue on our review Lumia 900 late last week, and the only thing that brought data services back was a full hard reset (we had no issues the full week we were using the phone before our review was posted, for what it's worth). ..... The issue supposedly stems from the way the IMEI (a unique serial number) of the phone is registered to AT&T's network. AT&T is pulling the phones with the affected IMEI's from store shelves, but that hasn't stopped a few from being sold to end-users. ... For many users problem is mysteriously fixed. And the problem was the same with the Titan.
As you say it is kind of tough to tell people that they need an over the air update when they have no wireless data connectivity. Microsoft servers (not vendor's servers and not carrier's servers) push tested and straightforward wireline/cable/FTTP updates to PC via Zune which in turn sideload over USB to Phone although recently and since OS 7.5 simple updates or apps under 20 MB can be pushed by the carrier. AT&T is feeling its way with that, even with Android and iPhone (since iOS 5). OTA and FOTA can be a tricky business. So far as I know Red Bend supplies an OMA-DM client for vendors of all four of the Major US networks for FOTA and other device management tasks.
Wise to remember that The Lumia 900 and HTC Titan II are the 1st 2 LTE enabled devices on AT&T. It is difficult to know exactly who and what exactly caused the existing problem: i.e. Nokia, AT&T's back room, AT&T's SIM card vendor/personlizer(s), MS WinPhone OS 7.5 limitations, some combination of the preceding. It doesn't really matter. There's been no finger pointing. Nokia has taken ownership of the problem in very timely fashion although Microsoft who controls updates on their servers and AT&T were undoubtedly involved in choosing and validating the solution and while it won't erase the stigma of a blemished launch entirely, it certainly minimizes it.
