 Same thing happened to me. The service center also denied any help saying stuff like the previous versions had bugs and all sorts of non sense and telling me that the next update i will be allowed to download.

Due to this problem Nokia care decided to change motherboard , they said we already flashed software thrice,so its a hardware problem.... Hope this time after replacement my device will become certified
Simi started a topic a day ago I just found a working trick to certify Nokia 6 in playstore, my Nokia 6 is also uncertified after service centre flashed it.... TRICK- First of all u need (1)- OST tool 6.0.4 version... (2)-PC running windows 10 ( use any but works perfectly without drivers issue in windows 10) (3) SD card (4) Data Cable... (a-)First off all install the OST tool with patch... (b) Download Firmware update of TA 1021 India from the net, extract it ,it should be .nb0 extension (c)- Download December 2017 security patch of naught of TA 1021 / TA 1023 ,put it in SD card (d)- Now reboot to recovery menu using hardware buttons to install this update from SD card... Select apply update from SD card... Phone will end the operation with error i.e update is aborted... Again using hardware button power off your phone... ( We apply December update to downgrade Bootloader) Now open OST tool, select .nb0 file that you selected.... Flash it, it will take around 3-5 minutes... Now you downgrade to naughat 7.1.1 Now check for updates again... You will get oreo via OTA... After installation of oreo via OTA your phone will become certified again... And you will recieve all security updates upto September month... Cheers happy flashing... Trick working 100 %<
