@Zoandroid, so ever since I backed up using the above method I've noticed a significant battery drain. One thing I did in the last few days was moved all the apps I cld to the extsdcard so I'm not sure if that is causing my battery to drain quicker or whether it was doing the whole Safe strap and stock rom backup part. I was thinking of going back to the point where I restore the nandroid backup I made last week but not sure how to do that exactly. Can you kindly guide me if you know how?
In the clone of TWRP recovery you see when you boot to Recovery from SafeStrap, in the right hand column of "buttons" the 2nd one down is Restore. Tap that, and at the top of the screen under the Battery % listing will show "Storage:" and it should show "Micro SDcard" with some value of free storage on your SD card listed in parentheses. If it doesn't show that, and shows Internal Storage, then tap on it and select Micro SDcard, then tap OK at the bottom to get back to the Restore screen. This, assuming you did make your nandroid backup(s) to the real SD Card.
On this Restore screen you should see folder icons followed by the names of every nandroid backup you have made to your SD card. Tap the one you want to restore. The next screen lets you opt to restore any or all of the selections you made at the time of backup. For me, that shows both Data and System. You want them both if you are wanting to take your phone "back in time" to that backup file point.
With your selections checked (both, as mentioned above) at the bottom is a Swipe to Restore sliding button control. Swipe that to the right.
You'll see status messages on the screen and probably a progress bar. (I say probably as genuine TWRP has one, but I have never restored a SafeStrap backup nandroid yet, so I can't be certain). It will take some time, so let it finish. When complete it will show you a Reboot button. Tap that and reboot back to the System (not back to Recovery), and you should see things just as you had them before you made the backup. All your apps, settings, everything. Neat, isn't it? This, and TIBU are THE reasons I started rooting Android devices.
Yes, I've used some custom ROMS on devices, but if there were no custom ROMs I would still root just for these 2 abilities.
One more thing. You might want to verify in the Advanced/Settings/Screen that the silly power saving feature is either gone (it seems to have mercifully been removed from SafeStrap 3.75's 'TWRP v2.7.1.0' version) or is turned OFF if it shows up in whatever version you have. If it is on, it shuts off the display every few seconds, making you think the phone has died during these critical recovery operations. I am SO glad to see it has been removed from the version I have!
