Use External SD Card as Internal Memory on Droid Razr

Advertisement

One of the limitations of having both an internal storage and an external SD card in our phones is that some apps are unable to read data on the external SD card, as the internal storage is seen by those apps as the external SD card and hence they don’t read the actual external one. This is specially prevalent on MIUI ROMs, as it fails to find music on the external microSD card as well as not being able to browse it in the file manager.

XDA modder pajn has come up with a script that mounts the external SD card on your Motorola Droid Razr as the internal SD card, and vice versa. Though it has only been tested on MIUI ROMs, it should work on most other ROMs as well.

Let’s take a look at the procedure.

Compatibility

This ROM and the guide below are compatible only and only with the Motorola Droid RAZR. It’s not compatible with any other device. Check your device model in Settings » About phone.

    Can someone PLEASE get this adapted for the Razr HD!?

    I’ve looked at vold.fstab and it’s different than the one linked to in this article.

    Here are the relevant bits as they appear on my Razr HD:

    dev_mount sdcard /mnt/external1::lun auto /devices/platform/msm_sdcc.3/mmc_host
