Was this discussed? Where can I find info on...?

You’ve tried on the TCL?

yes make sure to send three empty vb first

With fastboot?
How do I make an empty image?

It will probably work to change a text file into a bin format. I once did a damaged recovery, empty should work to, just proceed at your own risk and Make sure to send empty 3 vb.

?

Yes

Check this out for flashing empty vb. You could use the empty image from there for recovery

Does US Mobile Dark Star work on the Kyocera E4810?

Someone I know just tried it and he only call. Texts don’t really work and data doesn’t work at all.

Is it an APN issue.

Likely it wouldn’t work
The 4810 is verizon

Even if it’s unlocked?

Hmmm… How was it unlocked?
If it was unlocked and it has the correct bands to run att then yeah, it’s the apn. But,
does it have the att bandwiths??

Not true if unlocked, it most likely will work.

Yes it’s probably an APN issue.

What is the cheapest service to get for an unlocked waze device?

Don’t know for sure, but should be around US Mobile…

Not so simple, their data only (“apple watch”) plans have to be connected to a regular line…

Search for iot data plans.

Does anyone know how to block app installation on the TCL?
I mean even with having a rooted boot img.
I think it may have been discussed somewhere but I can’t find it.

possibly could be added in build.prop also

that would work too, but a boot image running resetprop can change that, so the best way would be to change the line in services.jar
