i have a nokia 6 ta-1021. until now, there ist no september update available. also, i wasn't able to find an offical nokia or hmd global server to download and install the update manually. only some non official sites offer the september update to download. without at least any offical md5 hash, these update files can contain nearly everything.
how can i get the september security patch for my phone?
No, the carrier is not in the game. The query for the OTA Update Server contains the carrier of the SIM Card. If there is no entry for our phones with our carriers, the OTA Update Server Returns, that there is no update available.
I bet, the specific carrier is still present in the query after removing the SIM Card. With the factory reset the carrier is erased. I will test this in the next days.
Now we have to find the android Service which read and save the carrier Information on the phone. Only with stopping this Service and erasing all of his Service data should have the same result, as removing the SIM and a factory reset.
if you have bought your phone from a carrier with a carrier specific Branding, then it is possible that you get updates later or never, because it is up to the carrier to accept updates from GMD Global
@user1507320204074, thank you very much for sharing the "Factory-reset-without-SIMcard"-trick. I own a Nokia 3, but had the same problems: no updates since July. Your procedure worked with Nokia 3 also.
RichardFQ is my new favourite person. I put in a SIM for a different carrier and rebooted and BINGO - all the updates! No factory reset required even. Thanks for your help mate.
Same problem with my Nokia 3, I think it is problem of the variants that sell the operators since the international variant TA-1032 received 7.1.1 but mine sold by Movistar Chile is the TA-1028 and not received the updates
