[Rom] How to update and not lose any data? - Android Q&A, Help & Troubleshooting

First of all sorry for my bad language
I've a Lg 2x (Aka Optimus Dual) temasek's UNOFFICIAL BUILD, now i saw an update from temasek. I'm asking how i can install the new room file as a simple update without losing any app/contact etc.
Well if it's possible what's the correct way to do an update of a custom Rom ?
Very thanks,
Sorry for the question but i've googled and nothing, also searched here but nothing

if its a update of the same build jus erase cache and dalvik cache and install the rom. then ur data remains untouched. but if the rom is different u need to full wipe. data will be lost. but u can sync contacts to gmail and retrieve back any time.

What does errase cache and dalvik cache do? Does the settings stay the same or do you have to set them again when you update? If it delets settings...can you update without errasing cache?

Nope...clearing cache and dalvik cache only wipes unimportant info...your settings will be there as long as you don't press factory reset...

exactly. but look for the requirements for the update. sometimes even updates may require data wipe if the dev states it.

All the above is good and true. I'd like to add that I always make a ROM backup with ROM Manager before I update my ROM. That way, if something should go wrong, I can get back to where I was before the update.

Not recommended to Samsung Galaxy Ace this ROM Manager because it bricks your device!

Dude you could just install Titanium Backup from the play store and back up all the apps and data you want to. And yeah, your device needs to be rooted. Cheers.

Scripts and wipe

Hey, so I was wondering quite a long time now (and I haven't found an answer), when I am changing either Rom or just want to wipe data/cache/dalvik cache... will the scripts I installed disappear ? Do I have to reinstall them ?

If you install another ROM you'll have to reinstall them. If you are wiping,you don't have to, because you are wiping them user's data not the system data.

Yes,becuase it gets wiped when flashing a new rom.

[Q] Installing our selected ROMs data/cache

When we reboot into cwm recovery to install our selected roms, do i need to wipe the data and cache AFTER or BEFORE i install the roms / gapps that i want to? Need help here !
- One more, those who are experience like me when i installed (cm10 port by Psyke) noticed that music app does scan SD card, but then no songs are shown when the app launches, thus leaving it to be blank / left only symbols at on top of the screen . Is really music doesnt work yet for the beta release? thanks for any response

If it's the next version of the current Rom you have, then wiping /data and /cache partitions is not nessesary. If it is an entirely different Rom then you should do a wipe as the phone won't boot properly.
As for your second query, a temporary solution is to use a different media played. I had the same problem with the initial cm10 builds for the galaxy s3.

Data cache partition
Erm ok. But wiping cache partition doesnt really wiping my items in SD card right ? and u said if other roms need to wipe the datas and caches but i need to do it BEFORE or AFTER i install the rom? i mean before we install i need to press the wipe data n cache OR after i install wipe data n cache?

Wiping /data and /cache doesn't wipe your sdcard content. It only wipes your installed apps and its data.
Doing a wipe before and after doesn't matter. But generally we do it after flashing a ROM.

You can restore the backup with out data wiping since cwm recovery wipes /data and /cache before restoring a backup.

[Q] apps FC after rebooting any custom ROM....

I've tried several ROMs on my Neo MT15i, rooted, unlocked bootloader, alliance kernel 1.5, firmware .587. Now I'm on Thilinac Ice cream pureness 14 sp1. Everything is working well..... but... Every time I reboot the phone I MUST clean cache and Dalvik cache via CWM recovery. If I don't do it , after booting several apps go force closing in loop and the phone is unusable. I've had this problem also with other ROMs like Jelly-Sandwich, any release. Tried also to format sdcard without benefit.
Thank you for help
Try clearing app data from settings!
Then,reboot

Unfortunely it doesn't work....
It afflicts every app I install as user, either in system /data, or in sdcard.
After installing a new Rom, on a clean system, I use titanium backup to re-install my apps.

I do this every time I install new ROM
I've formatted system, data, cache, everything. Than reinstalled the ROM (Ice cream Pureness 14 sp1).
when booted I didn't reinstall anything from Titanium and tried a reboot......... As usual, Gmail and Google playstore
went FC loop. GMail and Playstore are apps coming with the ROM .... Than I rebooted in recovery, wipe cache and dalvik cache and .... all run perfectly and smooth... The problem is still there.
Next time I'll try formatting all, reflash firmware .587, and than reinstall ROM.

Exactly. I had this problem with JellySandwich too, I tried several ROMs, but, at last, what I like more is IceCreamPureness for its balance , smothness and for very good battery life.
And how u solve this FC problem?

explained in previous post.
The problem is related to the moving of apps to sd card or in system partition. It afflicts the managment of dalvik cache

I asked about that b4 and they told me it's ok about partitioning sd card.. I was suspicious about link2sd and u confirmed that now but iam disappointing the basic reason that I root for is to move all applications on sd card

[Q] Switching ROM and wiping

Hey guys,
I have had some issues with my current ROM. I want to change the ROM. I am looking to switch to OMEGA.
How would I do this, I currently have AROMA rom. Should I do a factory reset the just reboot into recovery mode and install that way? Or will just installing the ROM from zip work? Or if I do a factory reset do I need to root it again with Odin, or will I not need to root it?
Also for wiping the phone should I wipe my SD card? Or no?
Thank you I searched and found half answers for most of this.
You have to format /system partition and /data partition in order to get a clean ROM, otherwise you may run into some unforeseeable problems.
Don't have to wipe sdcard
Most ROM except stock are pre-rooted.

Ok just to double check what your saying.
I should do a wipe using the built in android factory reset.
Then just install the ROM using the recovery boot.
I will not have to use ODIN or any other soft ware. Just factory reset and install rom.
AW: [Q] Switching ROM and wiping
I'd factory reset in recovery, wipe cache and dalvik, format system and then flash the new ROM from your external sdcard
Please report if that way worked for you
But be sure to backup your apps with titanium backup

He's talking about wiping in recovery.
Dalvik, is kinda Java virtual machine on android, it does concerns you...

Nobody can tell you which rom is better .. All roms are amazing because of the work put into them try them out one by one.. you're not going to lose anything..
Ok cool. I installed OMEGA and I like that rom. I did a factory reset and wiped the Dalvik cache and cache. Will look around a bit more but so far so good....
however same issue with the phone. But now when the call ends it says process com.android.phone has stopped. Then i hit ok and phone is ok. It doesn't automatically restart then go really slow.
No idea about this, I searched however couldn't find a answer. Lots of phones and versions of android had this issue.
Any ideas would be great guys.

why not you backup your current rom first then try to flash a new rom without wipe data. if you not facing any issue on the new rom, then it's ok.
if you facing any issue, you must flash again the new rom with wipe all data. if you not happy with both, then you restore back what you are backup before.:fingers-crossed:

Yes I did. I factory reset. wiped cache and dalvik as well as formatting in the advanced options. I currently have Omega 44.2 installed. But I had the iphone app crashing with AROMA 30.1 and 30.4
Is there away to uninstall the phone app and then re install that cleanly?
I did this and still have the phone crashing issue.

There is no white data. only buttons available are force stop and clear data. If I press clear data it says all data will be deleted permanently including all files, settings accounts, databases. I assumed the files were the actual app.
I went to settings. Applciation manager and chose Phone.
......hit clear data then, do that for phone and contacts storage, the data bases get rebuilt the only thing you will have to set up again is which contacts to display and any ringtone options etc you may have chosen

As far i know, i wiped both Dalvik Cache and Cache without data loss.
The data you might refer is stored in Data partition (and if you wipe this, everything is lost).
Feel free to correct me, if I'm wrong.
Titanium bkup mate. Saves all game data +app Great app of playstore. Change rom and restore data and all will be well.

No but flashing a new rom will wont it. Op back up your game and data with titanium bk up before you even try and flash a new rom. Or dirty flash from rom to rom
And risk it. Dont worry about if you go to 4.1.2 or 4.2.2 or even 4.3 it will restore and work. Titanium bkup is a standard thing to have.

No it wont. Flashing a rom modifies /system. Data is in /data/data or /sdcard/Android/data
Much detail about backups in general > sticky roll-up > understanding the basics before rooting

Standard in flashing is wipe data. Dirty flashing is not recommended by any dev. Your telling me that if I do a proper install then the game/data will still be there? No chance. You can reinstall the game from playstore and your data wont be there. But if I did a dirty flash then yes if it boots up then it will be but only with a dirty flash. Thats like saying your contacts and texs will still be there
