Thanks

No you can't restore a data partition on another ROM, that'll cause problems. You use Titanium to backup only the apps and teen you can restore them on your new ROM.

Exclamation Question Regarding Firmware
I am quite confused about the 'firmware' part of the OPO. I have used a number of Samsung phones wherein I just needed to flash the ROM file only. The only thing I had to flash separately was the modem.

Coming to the OPO, what I don't understand is what the 'firmware' actually means/does? I am on stock CM12S 2I3 ROM right now which I have rooted. So if I wanted to go to say, CM12 based ROMs, is there something extra that I need to flash? I hope I am putting across my question properly! Any help would be greatly appreciated!

Firmware is everything in the rom that isn't system, data, cache or boot (kernel) i.e. modem etc.

Custom roms often only include system and boot so if you're moving from a cm11 to a cm12 based custom rom, you probably need to update the firmware.

Stock CM11S & CM OS12 roms and CyanogenMod nightlies include the firmware.

OK. So as I understand, a 5.0.2 ROM needs a matching firmware and same goes for 5.1.1 is it? Also, is there a way to check on the phone itself the firmware version I'm running? Also, if I go to a CM12.1 based ROM now, will I need to flash the firmware separately or can I download it from somewhere?

Hi all,
I have an issue with oné Enterprise app, not able to restore it via Titanium Backup. Seems like something is not backuped and then not restored. So app does not work after restoration.

I would like to "investigate" what's missing... how to do this...???
1) make a list of all files on /system, /data, Cache and Dalvik partitons?
2) then install app, test functionality, malé list of files again and create TB backup
3) uninstall app, restore it from TB and make a list of files for 3rd time
4) compare 1st and 2nd list - to find what was added
5) comapare 1st and 3rd list - to find what was added
6) compare last to lišta what's missing

How to do this? Thank you for help

Yes, you need firmware to match your rom.

The safe way is to flash the firmware whenever you change rom versions, so, moving from 5.0.2 to 5.1.1 you should flash the 5.1.1 firmware first.

You can get the necessary firmware from any full rom fastboot zip: CM OS12 (5.0.2) or a CyanogenMod nightly (5.1.1)

This may have been asked already but there are a few hundred pages to sift through and I've already been looking for awhile. I'm experienced with rooting and using custom recoveries and everything but I've never used a device without expandable storage, so if I were to create a nandroid back up, would I lose the backup when wiping to install a new ROM? Or is my best option one of the flash drive adapter things?

No, wiping doesn't touch your internal storage unless you specifically choose for it to. The best way to ensure this is by entering the wipe menu in TWRP and then selecting advanced wipe, from there you can select exactly what partitions you want to wipe (usually system, data, cache, dalvik cache).

Regardless of whether your device has a microSD slot or not, part of the internal storage is partitioned into an emulated SD "card" where your data gets stored. Pictures, videos, downloaded torrents, etc. Nandroids get stored there too. When flashing a ROM, first you wipe Dalvic Cache, System, Data, and Cache. As long as you don't wipe Internal Storage, all your saved content, including nandroids, Titanium backups, etc, are untouched.

It never hurts to use a USB OTG cable and flash drive though. Keeps your phone's storage free for other stuff.
