I wanna perform a factory reset before upgrading to ICS on my Xperia Mini, but I have a few questions first:
1. Do I have to do it via settings/privacy or for example via PC companion? is it the same as flashing a clean stock rom?
2. Since I lose all my apps, do I have to install them one by one again or there's something storing them?
3. Do I lose root and all the mods to framework and build.prop? Since I want a rooted ICS I need a rooted GB first, do I have to root again after the factory reset?
4. The nandroid backup everyone suggests, is it just to restore in case something goes wrong or is a restore really needed after the reset?
4. If I don't do the reset and upgrade to ICS, which problems may I encounter?
Thanks =)

1. You could simply do it via the privacy settings. Yes, flashing the stock rom (via RUU) will factory reset your device (but it will take more time).
2. You could make a backup then restore them or simply restore them from your Google account.
3. Factory resetting does not make you lose root access. You may only need to re-install Superuser/SuperSU.
4. It is a backup of all the partitions of your device which you can restore if something goes wrong.
4 . Data corruption may occur, your device may not boot (bootloop), overall laggy system.
Thanks! About the number 2, if I make a backup+restore, don't I get the old data back? I mean, doesnt it backup the entire system, or is there a way to backup only the apps? And besides, I didn't mod my rom a lot, except for something in the framework or some tweaks in .prop files, if the only things causing problems are in system modifications, I don't think I'd have many issues.

Yes, you do. You can backup your apps using Titanium Backup, but you can also restore your apps from the nandroid backup via Titanium Backup.

one quick question in setting up the upgrade from 1.3d to 1.4:
When using Titanium Backup, I back up all user apps + system apps.
Once upgraded to 1.4 can I restore also system apps, or I can mess something doing this? It's better to restore only user apps?
Thanks
You don't need to use any apps to restore after upgrade. All the apps should still be there if u only did an upgrade without a reformat factory settings
Thanks but if I understand correctly the Dexter's instructions, he recommends to do a Wipe (Factory Reset) before and after installing the ROM. In such a case, I guess that all apps and settings will be lost. And then, it is when I gess I need to restore from a previous backup or otherwise I would need to restore everything manually, app by app.
Even if you don't wipe out you apps and data, it maybe be better if you do a backup in case something goes wrong... Bad things happens when we least expect
OK, but my original question remains:
Once upgraded to 1.4 (and making a wipe) can I restore also system apps by using Titanium Backup, or I can mess something doing this? It's better to restore only user apps?
What system apps that you want to back up with Titanium? I recommend you to check the change log from each of Dexter version to see if any of your system apps is being changed in the new update or not. If it's changed in the new update then don't back up it, otherwise it's safe to do so.
OK, thanks. That's what I did.
Since after installing the ROM, all applications there were the ones coming with the ROM, I didn't restore any existing app, assuming it is already the last and correct version. I was therefore restoring only those missing, and it worked fine. The only problem, I guess, is that by doing this way I didn't restore the app data for those apps coming with the ROM. Not a major problem.
This might be a stupid question, but is there any way to get my backup restored? I just tried to restore a backup through CWM but it wiped my villainrom flash and went back to what I had before.

Is that not the whole point you backup XX try ZZZ decide you dont like it and restore the backup of XX which wipes ZZZ .
jje
yes I realized that eventually, I thought the point was to save your data like apps, themes, etc. so you can load them in the new rom. my apologies
You should not restore cache. When you boot up to a new rom, it will just redo the cache anyways.
As for Clockwork Recovery backup and restore, it does a full backup of the rom, including cache and user settings and apps. It restores back to the original rom as well.
I think you want to restore your settings and applications of your old rom into villainrom. I wouldn't recommend it as it settings for stock and custom might be different and can cause weird issues.
on that note, is there any way to access that information after flashing the new rom (to see what apps i'm missing and download them all again so I don't have to just redownload each one as I realize i need it?) without restoring the backup
nevermind I ended up just going back to my old rom, thanks for the replies guys
There is this wonderful app called Titanium Backup, it backup all your wonderful apps. This way, when you switch ROMs, you can just restore all those wonderful apps that you have been stockpiling.
Hi,
4.2 of Jelly Bean update could be imminent for my Nexus 7, and I'm wondering about what and how to backup before the update. The question I think is a general android one though... which is why I'm posting it here.
This was going to be a question about factory reset... but reading other posts I think I now understand that factory reset just deletes data/cache, so I think any time you do that it's just gonna return the device to a clean ROM state without changing the ROM. (whatever flavour/version ROM is)
When a ROM update is applied (either official or manually flashed), I guess it wipes everything, is it like a disk format or something like that? I have installed CWM recovery and rooted my device, I think the update will unroot it, but will the CWM recovery still be loaded?
And then, what backup should I take before the update... I think a Titanium Backup is a must, I understand how that works. But a Nandroid backup too? Or is that more like taking a disk image, would that be useless to restore after the ROM has been updated? And if so, does that mean any old Nandroid backups should be discarded?
Once the new update to 4.2 is installed, is it advisable to take a Nandroid backup immediately, or better to download the stock 4.2 image and keeping it as a starting point? (does this amount to the same thing?) I guess this is where a factory reset would return it to stock (providing I haven't moved anything to the system apps)?
Or is it possible/better to use a Nandroid backup as a point in time image of everything that's been installed on the device after adding back all the apps etc? I guess that leads me to wonder if the Nandroid backup is needed at all if I'm going with the Titanium Backups...
Thanks a lot and sorry for the lengthy question, I've seen many posts touching on this

1. OTA updates should let you retain your apps.
2. Clockworkmod will still be installed following the update.
3. Nandroid backups are like a system image it makes a backup of everything on your phone (Minus sd card external) at the exact point in time when you make the backup. If you restore the backup it will restore your phone to the exact state it was in when you made the backup. You only need to keep a couple of your recent nandroid backups on your phone.
4. After the 4.2 update you can either make a backup or use a factory restore image it will make no difference. Factory reset would return it to stock.
5. You can use nandroid to make a backup after you install your apps in fact I would recommend this that way you have a convient restore point. You can also backup your apps with titanium backup.
Hope this answers some of your questions .

Excellent, thanks for the fast reply, you did answer my questions!
I was misunderstanding then about the 4.2 update, thinking it was equivalent to flashing a new ROM... you clarified it for me, seems it's less severe than that.
I think I'll go with your point 5 to use a Nandroid image for a convenient restore point after the OTA happens
I am currently stock rooted and believe I may have flashed some mods that aren't playing nice with my phone. My backups dont seem to be working as there is a md5 mismatch the second I choose to restore. So, no custom ROM, just rooted with some apps removed and some mods added. What would happen if I were to factory reset?
It erases your data, settings and apps but your mods kernels and roms (if any) stay the same also it would NOT restore any removed bloatware

Do you have a nandroid backup or TitaniumBU? If so, and you're ready to go as far as wiping the phone, you might want to first try restoring from either of these. For CM/Nandroid, you can try an 'Advanced Restore' and just restore System. (is this where you're having the checksum error? if so, never mind).
In Titainium, you can restore backups of your system files (e.g., SettingsUI.apk) that are sometimes over-written by mods.
But if you want to sure, you're probably best off just doing a clean re-install. Find one of the Stock MDK ROMs in the development thread and flash one of those (follow instructions for that particular ROM).
You might be able to save some time after flashing by either doing a TB first and restoring your Apps+Data afterwards, or do a nandroid and Advanced Restore / Data.
Do NOT flash stock ME7 (except for DarkSlide SG4) or you'll lose root and recovery...maybe forever!
Hello all!
I know that there is plenty of threads about going back to stock but what I want to know is if there is a way to restore apps and data of a multiuser environment after the rollback and eventually which is the safest way.
Furthermore.. that's a bit ot.. I've not backed up drm keys when I installed cm10.2.. what will happen when I reinstall stock? will I only loose bravia as I've previously read?
thanks!
Theoretically, the best way to keep data would be by flashing the .ftf without any wipes, but that can cause problems, such as misbehavior and force closes (slow downs).
Another option that is more safe in that matter, however might not save all the data, is to create a CWM backup from your current setup, copy the backup files to somewhere, do a fresh install for Sony fw, then installan app called Nandroid Manager, to restore your data.
And, yes, since you didn't backup your TA partition, you won't have Bravia Engine anymore...
