[Q] who can share 15 to 21 OTA cache file.

---

We are from china, we used CN pad.
CN pad not have google service. The only way is flash other area rom.
21 root, must 15 root install root keep OTA to 21 get root back.
But CN pad can not OTA after flash to US rom, OTA may check serial no.

Does anyone can share this file /cache/dlpkgfile? Get this file after OTA download finished before reboot, need root right.

Just to clarify:

You need a rooted user to be on update .15, download the OTA update but don't install it, navigate to /cache/ and copy over the dlpkgfile? And this is a US user you need to do this?

I'll be glad to downgrade and update again if it will actually help you out, what will this file do for you?

I actually need the .21 OTA cache file as I have an Unknown serial nuber problem with my prime and can not receive OTA updates.

So then, would that be the file I get when upgrading from .15 - .21? Because right now there is no such file in my /cache directory and I'm at .21.

The cache file is deleted after you update.

K. I'll go about downgrading later, I wonder if there's any way I could get the cache file moving from .11 to .15 or whatever again. I'll post the cache file as soon as I have it.
