Installing CM 12.1 over stock without loosing data? - Nexus 4 Q&A, Help & Troubleshooting

Is this possible? Im familar with extracting bootloader, radio, system and boot img's from the factory image zip then using fastboot to install while keeping all settings and data. Can I do this to install Cyanogen or will it break everything?

What type of data are you talking about?
If you are talking about apps and app data, then I don't think this is possible. All your data (pictures, music, and other files/ folders) on the second partition (other than device) would be intact even if you do factory reset from recovery.

First this is a question, you are in the wrong sub forum. Second, system apps you can forget. But user apps (those you install), just backup with titanium Backup and restore after installing a new rom. I do this every time I change roms

Thanks. I thought that there would be too many differences between stock and CM especially gapps. Think I will need to do a clean install from TWRP to have CM12.

What are the bugs of CM12?
Sorry for my bad English

[Q] Need to update rooted T-Mobile G2

Rooted my G2 in December 2010 but did not install any custom ROMs on it. I have SuperUser and ClockWork Mod on it. The OTA 2.3.3 update finally made its way to my phone, but does not update because of root.
I have seen too many threads explaining how to update the phone, leaving me confused Can somebody please explain how to or point me to a relevant thread.
Thanks.
There are pre-rooted versions posted in Development. Just download from there, put on your SD card, and flash from ROM Manager. You are also S-Off?
If you install an official ROM, you lose root. You don't want that.

I used this one: http://forum.xda-developers.com/showthread.php?t=1211143
bone stock pre-rooted OTA. Flash through CWM recovery. Doesn't replace Radio or anything. Its just a ROM.zip you can flash. Wipe data/factory reset before flashing of course.
Thanks redpoint73 and martonikaj for your help. I was able to update the ROM.
One last question for the folks here, I performed a Titanium Pro Backup before upgrading the ROM.
Which one of the following restores should I perform now that I have upgraded to 2.3.4?
1. Restore missing apps with data
2. Restore all system data
3. Restore missing apps + all system data
4. Restore newer versions of user apps
5. Restore all apps with data
Thanks.

I usually do 5. Restore all apps with data when moving to a new ROM. (never restore system data unless you're re-flashing the same ROM). I usually select it, then scroll through the list and uncheck some apps that may cause issues. Things like Clocks, Browsers, etc. often overwrite system-level apps and can cause problems. YMMV.
Its in your best interest to perform a nandroid backup before doing a big restore of 100's of apps, as there is a chance that there may be some problems or incompatibilities that cause issues, and you want to be able to go back to a state before installing all those apps to troubleshoot without having to re-flash the entire ROM.

ROM Backup

Hi,
Is there a way to do a complete backup of the current ROM? I know I can always reflash the stock firmware but I'd like to keep all the installed apps/customizations.
Thanks!

If you flashed CWM recovery, doing a nandroid backup (boot into recovery, backup and restore->backup) will back up your entire system, including ROM, your installed apps, accounts, settings, the whole kit and caboodle. If you're just worried about your own apps, you can use an app like Titanium Backup to back up all your apps and their data and restore them after a wipe.
Just to be clear, flashing stock ROM through odin won't actually wipe any of your apps or data, but it's usually a good idea to do so manually when changing firmware versions, as you may run into problems, usually apps force closing, if you don't.

Thanks for the info, and sorry for the late reply...
I would be interested in doing a full ROM backup. Are there any known issues in flashing CWM? so far I have only rooted the stock rom.
Thanks!

You won't lose anything. Just make a CWM backup (as a failsafe, you shouldn't need it) then flash the new version over the old version. Don't do a wipe or anything like that, just flash it. After the update is completed, clear the cache partition (from the CWM menu) and the dalvik cache (in advanced in CWM) and reboot. First reboot may take some time but after that it should be as it was before, just with all of the updates to the ROM.
Just install new ROM
I have some situation like you have, Typhoon 3.7.0 update to 3.8.0! What I did is just pull the ROM to SD card, and then enter recovery choose " install a zip from sdcard" choose your files, and install and it just all set! Your personal data will not be delete!
i just installed this ROM from MIUI, didnt do task29, installed and wipe cache and dalvik.
i like this ROM but the Cynogen settings keeps giving me FC
anyone knows how to fix it without dong a wipe clean>?
also if i have to do task29 how to backup and restore my data? sorry noob here.

I don't quite understand your problem with Cyanogen settings, but to backup and restore just use the CWM backup. It will backup literally everything on your phone and any apps you have on your SD card. If you ONLY want to backup your app data and other data which you want to restore onto a different ROM, you can either:
1. Create a CWM backup and when restoring, go to advanced restore and restore data partition
2. Use Titanium Backup to backup apps, Super backup (I think that's what it's called at least) to backup contacts, SMS and call logs and (probably unnecessary but you might need it) APN backup & restore to backup your APN settings.

nandroid + flashing/restoring across roms

I'm having a little trouble understanding nandroid vs. other forms of backup and would appreciate some clarification. I'm running CM nightly on my Fido (Canada) G4. I took a nandroid as well as titanium backup of the factory stock image before I flashed CM.
A poster in the last thread I made suggested if I wanted to restore to stock, I could simply restore the nandroid, but I've also seen people say you shouldn't use nandroid to go across ROMs. My understanding is that nandroid is like having a filesystem backup, which would obviously not react well if you restored it over a new operating system (e.g. two different versions of windows). Or is nandroid more like say Acronis, which takes an entire disk image and overwrites everything?
Other misc questions:
- If I do restore via nandroid, do I need to wipe all data / cache / system data before or after the restore?
- I assume I can use titanium to restore SMS + all non-system apps across ROMs, which would save a lot of time.
- If I'm going from one CM nightly to another, would titanium work for system apps (e.g. all my settings, or contacts, etc)
- If I want to flash a new CM nightly, do I need to follow the entire wipe procedure just as if it were going from one ROM to a completely different one?
Thanks!
always make a nandroid in recovery. i recommend keeping it on your micro sd card. in the event you need to return your device to it's previously functioning state, restore the nandroid in recovery. if you are running an aosp rom and your nandroid is touchwiz, wipe data, cache & dalvik before restoring the nandroid. if the backup is on your micro sd then feel free to wipe system as well.
if you want to flash a nightly or update to a rom you are currently running, simply wipe cache and dalvik then flash the update, gapps and any custom kernel that you may be running.
i cannot answer your titanium backup questions because i do not use that program

yes, that's about what I have. ok, thank you for the clarification of what to wipe! that's good to know.
re flashing a nightly/update: using your method should preserve system data yes? so no need to reinstall all apps or system data?
and thanks, I'll hold out hope that someone with titanium expertise will be able to answer that one

yes, system/user data will remain. understand, however, that if you perform one of these dirty flashes and you have a problem with the functionality of the ROM, you'll need to do a full wipe and flash to see if this clears the issue before you report the problem in the development thread.

Your right on both titanium questions.. However its not recommended to restore system apps you backed up on a aokp/aosp ROM to a touchwiz ROM and the other way around... Other than that like I said your fine

[Q] Change rom question

I have a nexus 4, which unlocked and rooted standard android on it.
I have backed up my apps with titanium and backed up the rom via TWRP.
My question is if I change to a different rom using ROM Toolbox, will I be easily able to restore my apps from the phone or do I need the backed up elsewhere, does all the phone content get wiped?
Related to the above can i restore my existing rom, easily if I want to go back to it?

You do not need to wipe (format) your internal SD card so all your data will still be there (songs, pictures, apps on which you have performed backup on via titanium etc).
You should be able to restore your apps with titanium but sometimes there are apps that cause some problems.
And sure, you can go back to your nandroid backup (your old rom) at any time with TWRP.

Thanks for the advice.
So if I use rom toolbox, I just download and install a rom as zip, but do not wipe anything, is that correct?
