Turn AT&T into a the global variant

[filfat]

After a bit of experimenting (and a lot of fights with the bootloader since it always decided to relock itself preventing me from simply using fastboot) I managed to get the global fw to run on an AT&T device.

TLDR: You can just dd the global partitions while rooted and then restore through adb sideload.

quick question.
for step number 2 "Use payload_dumper from the rooting guide to extract the partition images", am i extracting the partition images from the Global version or the AT&T version?

So does this mean anyone using this firmware has sim unlock? I saw on the GitHub you mentioned it works on another network outside of AT&T

The global version. The script will then dd those to the correct place

I had great success with this and have relocked the bootloader as a normal duo device thanks, if anyone has any questions about how i managed it let me know. Thanks so much @filfat

I just wanted to thank the OP for making this process easy with the instructions and for the new life given to this phone. Now that the phone has been converted to the global version what happens if another update comes down the pipe? Do we flash the global version, at&t version or sit tight and await further instructions ?

First:

1|duo:/data/local/tmp # chmod +x globalify.sh && ./globalify.sh;
./globalify.sh[7]: syntax error: unexpected 'newline'
1|duo:/data/local/tmp #

Why error?

I'm on step 8. At 47%, it shows me an aborted installation message. Reason: incompatibility.

How to solve it?

I took the system from:

The way i did it to simplify was to just copy and paste the commands unfortunately my shell wasn't executing the script correctly I had some errors

I have the same question when the duo announcing the newest OTA. The at&t Duo which turned to a global variant can update by OTA or must flash the new images by this method.

copy and paste what commands exactly? are you saying do each .img 1 by 1? or something else? i copy/paste the commands from the github but i got stuck at 47% same as the other guy.

I just received a OTA update and it failed. I followed this method to unlock my At&t version.

How do I go about updating, but more importantly which OTA should I be looking to flash, At&t or Global?

Can you please confirm if esim capability was available or not after installing global variant image?
thanks!
