just to let you know i tried this to boot up three different kernels and three different roms to switch between (cm10.1, 4.1.1, 4.1.2) and unfortunately it did not work in any order because i believe (i'm no dev or anything) safestrap cannot swicth kernels when you boot into different slots so you have to manually boot the right kernel (boot.img) in twrp recovery and whenever you do that it stops safestrap from working. probably because it was just made for moto based roms only and not meant to switch kernels because we didn't have access to the bootloader when it was made. so bottom line... i would say don't waste your time like i did. i am just going to wait and hope that hashcode is possibly working on a twrp recovery that has the ability to boot multiple slots and kernels, if thats even possible. but either way once we get a fully functional cm or aokp rom life will be good right?!
p.s. if i'm wrong and you get it working let me know.

Yeah I see your point. I think you are correct that SS can not switch kernels so the slots have to be the same Android version or compatible with whatever kernel you have. I think folks were working on a recovery that had rom slots. Until now it was not useful to everyone because of the locked bootloader. Thanks for telling your experience.

just to be more specific about this, when you backup and restore in safestrap you'll notice 3 check boxes. system and data by default and cache is optional. when you switch to twrp, like i did, you'll now see 4 check boxes, system data and BOOT and cache is still optional, and the BOOT checkbox is the important one, that's your kernel

Can you just use safestrap

Can you just use safestrap

Yeah, you can continue to use safestrap. If your bootloader is locked, this is your only option. If you unlock your bootloader you can use a recovery like TWRP which will allow you to flash roms and kernels even older or newer versions. You don't yet have rom slots in TWRP but you can backup and restore roms to SD card, internal or external at will.

Yeah, question: what can we do from the bootloader screen? I have no options, if I press power the phone starts. Vol up/down don't do anything. Is this normal?

If you are in AP fastboot then yes that is normal. AP fastboot is just used you flash images and such to your phone via rsd lite or fastboot commands.

In TWRP, is it necessary to wipe system/data/cache before restoring a backup of a different rom?

Its not necessary but do it anyhow just to be safe. The restore process automatically wipes these partitions for you.

Ah thanks. I'm still trying to piece this all together. So this is the same screen you perform fastboot actions from. Got it. Now to figure that out.

If you need any help feel free to pm me or find me in the chat room this evening.

Thanks a lot! I think I will need more help, I'm new to motorola and I'm afraid to screw anything up.

I want to flash the 4.1.2 DST ROM and I'm coming from 4.1.1. I'm just not sure which order to do things. Do I need to flash the the boot.img before or after flashing the ROM?

[jld]

Oh, no kidding. In the other topic, it seemed as though people were having to flash the 4.1.2 boot.img along with the ROM. Looks like I'll be flashing soon then! Thank you!

[jld]

It's all good. I did need to flash the boot.img, but it wasn't a problem at all. Everything is running smoothly so far. Your post gave me the push I needed!

I always backup the ROM and include boot and cache. Theoretically you should be able to restore this and come up running since you will reload your kernel (boot) and cache. I have been successful doing this, However, it is never a bad thing to wipe cache and dalvik as others have said. It only adds a few minutes to the first boot of the restored image.

I'm in TWRP v2.5.0.0 and looking at the Mount section and the only options I see are:

Unmount Data
Unmount Cache
Unmount SDCard

Use external SD Use internal SD

Mount USB Storage

I'm not seeing the option to mount Boot. Is this because I haven't wiped my phone? I am rooted and unlocked, deleted SS but haven't flashed over my stock 4.1.2 yet.

[jld]

Do you mean mount system? That's the one you need.
