Hi, my phone is Virgin Mobile LG Optimus F3 LS720V6, Android version 4.1.2
I had the same problem as Tolkien. My original goal was to back up my phone, before I install some things on my phone. So I followed the instructions here to get CMV 6.0.4.8 on my phone. Then I booted into CMV to see if it worked. It did, I didn't make a back up yet. I was checking out the recovery rom. Then I just wanted to get out of it and get to my android os to make sure I still have all my programs, etc.
It displayed the same message as Tolkien said. And I was confused, and I didn't know what it meant.
"Rom may flash stock recovery on THIS CAN NOT BE UNDONE."
No
Yes -Disable recovery flash
I clicked "No", and for some reason the first time, it reverted to factory defaults without my permission. (Even deleted some of the apk apps I saved in folders) Why would it do this? I just wanted to exit safely without it doing anything!
I didn't have much stuff installed on my phone to begin with. Anyways, since, then I rerooted my phone. And figured that this was just a one time factory default on the first install on this. Or is this a threat every time you go into the recovery program?
Anyways, I rerooted the phone. Now, I went to back up my phone per options. To see if this program works. I got this error:
"Error while making a backup image of /data!"
I figured this was because, there wasn't enough space on the phone. That's why I got this error. It was running out of space. I'll probably have to buy micro sd card, to test it. To make sure it can keep back ups, as I'm installing new apps.
But anyways, my main concerns are this:
Why did it default to factory settings, when all I was trying to do was get out of it? It only does it once? If not, how do I prevent it from doing this? What does this really mean? Should I have pressed yes? Is this a normal function when you flash something, your phone goes back to factory defaults. I'm kind of new to using phones. So just asking.
2nd, not sure if this will work when I test the actual back up before installing new apps, and if it decides to revert to factory defaults, and then I go to recover back up, and it doesn't work. Per what Tolkien was saying.
3rd, what if I want to uninstall this rom, how do I do that? Just in case, I choose to go with another one. Just in case, because I still want to use this app, but I want to make sure it works correctly.
Sometimes the phone has a Kernel Panic. When it does, it wipes the /data partition. When you reboot into your phone, it's the same as performing a Factory Reset. (Which wipes the /data partition)
For the Yes, or no question, choose 'no'. You should go back into the recovery and wipe any backups you've already made. Make an 'advanced backup' and just backup your system partition to test. You shouldn't have any issues. For a complete backup, you should have a minimum of 2 gigs free. I'd recommend at least 3 gigs free. You'll need an external sd card to make that happen. You'll never get that much space on the internal memory. The maximum size you can get is 32 gigs.
To answer your question about uninstalling a rom, To remove android, you only need to wipe the system partition. I wouldn't recommend doing so unless you know what you're doing. Usually when you install another rom, it will wipe the system partition for you during the install. All you need to do is follow the directions given to you in the rom forum thread in the first post. Usually all you need to do is wipe the 'cache' and 'dalvik cache' and then install the rom.
