## Clearing NVRAM
- For A7 devices, this might only work on older iOS versions.
- For 32-bit devices, this is to clear up NVRAM values from downgrading with cherry/powdersn0w.
- For iPhone4Down, this is for fixing 7.1.2 recovery mode, or getting stuck at Apple logo after downgrading.
- For fixing 7.1.2 recovery mode, try disabling the exploit first. If that did not work for some reason, you may restore to 4.3.5, 5.1.1, 6.1.3, or any other version other than 7.1.2 with the jailbreak option enabled before continuing.
- For fixing getting stuck at Apple logo, you may disable the exploit, then restore to 7.1.2 with the jailbreak option enabled before continuing.
- You may also use SSH Ramdisk, and run the `nvram -c` command from there.
