At last, I installed the fixed2 app over the 1.17.1 patch, both with the same signature (I changed with apk-signer) and works without installing the maps again...
Thanks to DeltaFoX & company

Well, I changed the signature on 1.17.1 & 1.17.2 to avoid uninstalled, installed, downloaded maps... Bla, bla, bla...
Needs time to upload to the cloud
