Awesome work on link2sd, really appreciate the effort of the development community. There is no problem with the scripts. This is the way that we have got this to work on the Huawei S7. I would be happy to do more testing for you. We currently do not have a recovery ROM and custom ROMs will come, but for now, the only way we can add mods at boot time is to use the install-recovery.sh. I can send you some screenshots showing link2sd working on my device. It would be amazing to have official support for the Huawei S7 for this application, and I am happy to help you out with testing it. I am sure there are many others in this forum that would like to help out too. If you look carefully at the script you will see that it is called a couple of other mods as well. One is the /cache remount mod. The other is a camera fix mod.
