CWM Recovery is considered the major utility among rooted devices. But sometimes, certain phones like Galaxy Mini or Galaxy Ace show an error on system mounting. Thank God, it can be fixed quickly. Moreover, the possibility of getting troubled by the same error is very few.
The error is an expected one and happens generally when you are trying to back up a stock ROM using the clockworkmod recovery. Please, note that you can’t do a completed nandroid backup of stock firmware. So, just install any custom ROM and then you can backup and restore anytime.
Clockworkmod Recovery Error Messages Also, sometimes you also face errors as given below :
E: Can’t open /cache/recovery/log
E: Can’t mount /cache/recovery/last_log
E: Can’t open /cache/recovery
Such errors are normal when you visit clockworkmod recovery while on stock Samsung firmware. Since
clockworkmod on galaxy mini is not fully compatible with stock ROM, you’ll get these errors.
Simply flashing a custom ROM on your Galaxy Mini handset removes this message from clockworkmod recovery.
However, if you don’t plan to install custom ROM, then it doesn’t make sense to install custom recovery like clockworkmod. So, I suggest removing it by flashing stock ROM via Odin which will overwrite clockworkmod recovery with stock android recovery.
Then, How do I back up my stock Android firmware? What if I want to go back to stock ROM after flashing any custom ROM?
Well, the fact that you can’t back up a stock ROM could be troublesome if you want to return back to official stock firmware on your handset. While some Samsung stock firmware is made available by sites like sammobile.com and sampro.pl, not all firmware might be available.
Moreover, not all devices can install these leaked firmware. Depending upon your handset and the fact whether Odin Multidownloader — a firmware flashing utility for Samsung smartphones — is available for it or not, there’s the possibility that you can return to stock ROM.
If required flashing programs are available and if (upgraded) firmware is available for your region then you can download it, load it in Odin, reboot your handset to download mode, and then flash/install it within a few minutes and change your handset to make it look alike to that of the very first day you bought it.
That’s why it’s always recommended to keep the firmware details of your handset (you can dial #1234# Samsung secret code and get the PDA, Baseband and CSC details of your current firmware).
If Odin or similar firmware flashing tool is not available for your handset, then I’d suggest you think carefully before moving to any custom firmware.
