Back up and phone restore?

is there an easy way to switch between stock and a rom?
in other words, i havent been able to succesfully find a rom/kernel/modem combo that gives me as good battery life as stock. i was wondering if there is a way to backup a rom/kernel/modem combo so that i can switch back and forth between that and stock without having to odin and/or flash everything again.
for example, if i am at home and can plug my phone into a charger everyday i would use a custom rom with all the fancy options but if im going on a trip id like to be able to switch to eclair to get as much battery life as i can. when i get back home i could just select an option and restore my rom/kernel/modem combo.
is there a simple way to do this?

are you sure TiBu is able to backup/restore modems? can you name some examples of roms that have a "no-wipe" version? thanks

TiBu is for backing up your apps, it will not backup your modem, kernel, and what not.
The problem you will eventually run into when flashing back and forth with no wipe is residual from your previous rom might interfere with your current rom. That is why most will tell you to flash back to stock, do a master clear, and then flash a new rom.
Your best bet is to keep on flashing roms til you find the one you like, I get 20 hours of normal use with the current rom I'm on, Doc's rom.

Maybe you could use CWM to make a nandroid backup of your stock ROM setup as you like it. That way you can revert back to stock when needed, but not have to reinstall all your apps. Just a thought; someone please correct me if I'm mistaken.

It might be worth considering the option to flash a custom ROM that supports OC/UV, and tweak around voltages, cap the max speed to something a little lower, and turn to EDGE when not in need of heavy data.
This might be easier than switching between ROMs.

thanks for the suggestions!

is this what a nandroid back up is? an image of the entire handset?
does this restore modem and kernels? thanks

No nandroids do not backup and restore kernels or modems.

[Q] How to get back to Stock Rom from ICS!

Hey Guys,
I have a rooted LG p990 from FIDO in Canada. I was wondering if i can get back to stock rom in order to get the ics OTA update.
I have NOVA HD REBUILD 1.1.0 (unofficial cyanogenmod 9) on it currently with the 2.6.32.59-HP-CM9-ICS-SUPERSONIC-RC2 Kernel.
I also have a nandroid backup of GB, but dont want to backup because i read online that the kernels are different and something to do
with the file system so you can brick your phone. Can i just restore the nandroid? or go back to stock? and how?
New to flashing, ROMS, Kernels etc. so i need help

You can restore the Nandroid without any problem. Everytime you change the ROM, Kernel will also be changed along with that. So after you restore the nandroid backup, your kernel will also be changed to Stock Kernel along with ROM. There wont be any problems.
Press THANKS if my answer is helpful.

If you are in Canada then I don't see how you will get ICS ota when LG Canada have said they won't release it there.
I doubt any release of ICS will be ota.
You'll possibly need to flash a downloaded rom to ICS anyway. Not sure if just changing regional settings will work but someone else can chime in on that one.

Are you sure, because i read online that ics changes the file system rendering the nandroid backup useless. And finally I don't need to flash a gingerbread kernel before right?, as nandroid restores my stock kernel.

Stock kernel is a gingerbread, one

Yes... The nandroid restore will restore the stock kernel as well. I have tried a few ICS Custom ROMs and restored my Nandroid backup and it restored the stock kernel.

One more question
Will the nandroid backup also restore the stock baseband and RIL?

Help - boot loop
I did the restore and it restored successfully, but when i reboot im in a boot loop and cant get past the white lg logo! HELP

FIXED
Changed to ext3 file system and it works now

Yes. Download a stock image from xda threads and flash it. You might have flash a new kernel if your coming from ics.

[Q] anyone willing to instant message me about some rom issues

hello friends i could really use some help and if anyone was willing to instant message me via skype or hangouts or fb messenger or whatever i would really appreciate it!
here is the problem i face:
So i was running dynamic kat 4.2, i flashed the 4.4.4 google dialer and it gave me issues, so i flashed back the old dialer (i wasnt supposed to do that!). I ended up getting "core.android has stopped" so i went to do a clean flash of 4.2 in safestrap and i made a nandroid backup then proceeded to wipe everything besides micro sd. (which is the way i have always been instructed to do it), I reboot my phone after the wipe and blam safestrap is gone and i just get a "samsuing galaxy note 3 boot screen". did i totally brick my phone? i know i can get into the stock recovery so i was wondering can i flash safestrap via the stock recovery or do i need to do the whole mj5 restore shebang i REALLY do not wanna do that!
any help asap would be massively appreciated!
thanks so much
-ben

If you have a N900A, you can just Odin to 4.4.2 NC2. It's much easier than the MJ5 restore process and you can use Towelroot to root and reinstall Safestrap. Just make sure you use Safestrap 3.75.

There is a stock backup by @rbheromax on this forum [link]. Also, you can RUU the device and return it completely to stock if you choose. If you detail out the issues that you're having, then a user might be able to assist you.

Revert back to Stock without wipe?

I have a Tmobile phone, but I have a rooted kernel, is there a way I could just flash a stock kernel through recovery and be done with root but keep from wiping all my data? Also links to such kernels would be appreciated, cause I'm not sure which to use.

You have to have a custom recovery installed via ODIN
Download stock firmware (there are several places around here to find it, and if you can't you can get it at Sammobile.com)
Boot into custom recovery and wipe all partitions EXCEPT INTERNAL STORAGE
Boot into download mode DIRECTLY FROM RECOVERY
flash stock firmware via ODIN
Profit

My apologies, but this will wipe my phone, I just want to replace the kernel with a non rooted version, not that firmware.

It will wipe your apps and settings (SMS conversations), but all of your personal data (Photos, movies, music) will still be there and the firmware includes the stock kernel.
As far as I know, this is the only way to revert to stock without losing all your data. I don't think you can simply flash a stock kernel, though I could be way off on that one. This method is how I reverted to stock.

Yeah I appreciate your input, but I have certain needs with the current data on my phone I can't part with yet. But hopefully somebody knows of a way, Thank you.

You can backup all of the data you need. Since all of your internal storage will be untouched, you won't need to back that up, but if you need your SMS and call logs and whatnot that stuff can all be backed up. What data do you need exactly?

I have certain game data, that I need lol.

Hi,
after you reverted back to stock, will you be able to receive and apply official OTAs?

Yes, however most, if not all of the ROM devs are going to update their ROMs to Marshmallow fairly quickly.
