Update from 6.5

[kameleon25]

When I first got this Blu R1 HD Prime version I was able to remove the ads and such by using the SP tool and directions here: https://forum.xda-developers.com/r1-hd/development/blu-r1-hd-remove-amazon-ads-ota-updates-t3427303. It is currently on 6.5. I have never updated it since then because I did not want to deal with ads again. Now I am having issues with it not wanting to connect to any mobile data (wifi is fine though and the sim card works in another phone) I figured an update might not hurt things. So with all that said, what is the best way to get the phone updated without bringing the ads back and not losing any data/apps?

Not knowing what is causing the data connection problems, it is not positive making update will help, but worth a shot.

I have posted updates that can be installed without being forced back into the ads system.

Will need to install TWRP recovery to install them.

Rooting the system is not needed to remove ads with twrp installed, if you do not want to have room rooted.

Since you are on 6.5 and not 6.6 you can use spft to flash recovery, or you can also use the dirty-cow method "tool" to unlock bootloader and then install recovery with fastboot(built into the tool )

If you don't have recovery then my opinion is use this to get recovery installed

Then use twrp to install one of these ROMs (recommend v21)

in my case two amzn 8.7 will show that it recognize sim, but no service, would need root to try and change IMEI, probably these phones are from a batch reported lost or stolen, but to be blacklist even in my country, a bit farfetched.

could just be an APN setting needs set to your carrier number/ settings.

Rebooting about a dozen times seems to have fixed it. I double checked the APN and everything but nothing worked. It just started working again. However I do still want to update it just to make sure it has more recent bug fixes. Thanks all.
