{Q} Updating custom ROM

Let's say i have gignerDX5 installed and want to update to v6. Do I have to backup all my apps and data (sms, phonebook) again?

Simple answer is no, you can just upgrade and it will keep all user data.
You should however make a backup in Xrecovery just in case something goes wrong, if all goes well then either move the backup to PC for later or just delete.
I updated from Froyobread to GingerDX and still kept my data and apps.

I make somethimes fullfactory in Xrecovery,if I switched to new room.It´s not bat to make back up in Xrec.of old room.It´s your game,wher you have back up.I use Titanum backup pro and my acount for phonebook and calendar.I do´nt need anything else for change the room.

Hi...
I have a question, and I didn't wanna create new thread, cuz its related to title
When I flash a new rom, its recommended to do a Full Wipe... Do I have to do that before or after flashing a Rom?

You don't need to do a full wipe when you update GingerDX. Just install it and reboot. I didn't have any bugs by not making a full wipe.

If you're coming from 2.1 to DX do a wipe, I tried first time yesterday installing rom and got stuck on cyanogen mod boot screen. Did a wipe, reinstaled and worked.
So do wipe if coming from other rom

Will flashing a new ROM wipe everything?

My main question is that I want to go to the ROM F1 Galaxy S II V6 - SP1 [Look & Feel Of Galaxy S II] or to another updated ROM.
I am coming from froyo 2.2 JK2 (with VooDoo). If I do this flash will I loose all my app data/other data? Is there a way to flash the ROM and save this data? I don't mind losing messages or bookmarks, I just don't want to have to install all of my apps again.
Thank you!

each rom is different, some are wipe version, some are non-wipe. There are a lot of good arguments for cleaning your phone and doing a clean install every time you change rom -- although most people don't, hence the length of threads with people having issues from legacy data and programs having incompatibility issues.
As a general rule prior to flashing any new rom or kernel you should:
1. do a complete nandroid backup in recovery
2. backup your apps using Titanium backup or similar
3. copy the Titanium backup, your photos, music, contacts etc. to your PC
4. then flash, clean and reformat as required without fear of being able to recover important data and files.
Again, some do this. Many don't. Depends how frequently you are flashing and how replaceable your files are.

+1 to that, I highly recommend you do a full wipe, Its not that difficult with apps such as titanium backup, It does all the hard work for you.
Doing a wipe ensures no bugs will be carried over and you will get the best result.
i wouldnt say a wipe is necessary when upgrading to a newer version of the same ROM

You can sync your all your contacts with your Google account and then just install and re-sync Facebook after flashing need Rom..

Nandroid backs everything up. It makes a disc image of the current rom. When you restore a nandroid backup, you restore the entire image.
You won't be able to restore the facebook links using titanium backup. Samsung updated the contact app when upgrading from Froyo to GB. I tried restoring data from Froyo apps to GB apps, and I got so many force close I ended up having reflash the rom. Note this only applies to stock apps. You can restore your market apps without any problem.

[Q]Nandroid Backup

Hello guys,
I bought SGS1 a while ago and changed some roms it was annoying losing my apps then my friend told me to use titanium backup it was more annyong cuz i had to backup one program at a time
then i heard about Nandroid Backup , so my question is:
if i change ROM lets say from MIUI to Darky or something and i used Nandroid Backup, all my apps will be there after i restore?

Your phone will shift back exactly where it was when you nandroid backed up ! And any progress from their will be lost !

Titanium Backup offers the option to backup all your apps at the same time, in case you didn't know. This may be only for the paid version though, I'm not sure. But considering it's the most useful app I've come across, it's definitely worth the money.

Actually if you try to restore a nandroid backup after switching to cm7/miui, your phone simply wont work as the file systems are completely different.
To go back to a Samsung ROM from miui you would need to flash a stock Samsung ROM via odin, and THEN restore the nandroid.
Anyway, beyond that remember the following...
Titanium backs up apps and app data, use after changing ROMs to regain apps.
Nandroid takes a snapshot of the entire ROM, use in case of problems to repair your phone.

Correctly said rschenck!!
Basically if you are on CM7 and want to give a try to MIUI just make a NANDROID backup for full ROM backup and try MIUI ,if you don't like it then flash back CM7 first and then restore the NANDROID backup!!
when it comes to Titaniuim backup , it backs up your app data,freezes them and the apps you want (only in pro version) on any ROM and restore back after flashing any other ROM, if you are on free version then you must select manually which apps to backup that's a pain in the ass !!
Use these according to your requirements....and dont ever restore one rom's nandroid with another as the Kernels,Filesystems,Modems,Bootloaders are entirely different and that could mess up your phone !!
i would prefer NANDROID over Titanuim !!

Thanks guys for this wonderful explanation...just one more query:
I'm currently using samsung Stock rom, CF root kernel, with lagfix(ext4), and some "framework" tweaks..and am thinking of trying CyanogenMod. So if i do a Nandroid backup now, and later decide to come back from cyanogenmod, can i just use Odin to get to ANY Stock rom so that the partitions, file systems, modem etc get back to a similar old format, OR do i need this exact Stock rom version, Kernel, lagfix etc before i can restore the nandroid?
is "kernel" included in a Nandroid backup? also, are Types of filesystems included (or "Lagfix" has to be repeated)?

[Q] Updatng from Gingerdx v022 to v025

Dear All,
please guide me to update my X8 having Gingerdx v022 to v025 without loosing applications installed. Does doing full wipe delete my data and application ? Also how to update CWM with the update ?

I updated from 22 to 25 without a full wipe. went fine and phone is faster and more responsive.. I dont have that many apps installed though. Just boot to CWM and install zip from location. reboot and you're away.
If you do hit problems just go back into to CWM and do a full wipe..

You need full reinstall , gdx v22 is cm7.1 and the v25 is cm7.2......

Full wipe is recomended because of different ROM bases. (CM7.1 and CM7.2)

To answer your question:
You can always use Titanium Back-up from the market to back up all user apps and data stored with them.
When you upgrade from v22 to v25, as Adrian said, it's a different version of CM, therefor, one must full wipe for better results. No one said it wouldn't work well without wiping, but it's just better to do it.
After installing and wiping, simply download titanium back up again, and restore your back-ups...that's how i do it.
Hope this helps...

Hello guys
I'm new here and in the endless world of Android, so please forgive me if you think that my question is stupid. I've already tried to find a solution inside the forum but there is always some part that I can't really understand..
You've said that v025 has cm7.2. Does this mean that if I want to install this version I need to first install cm7.2? Or is it included with the gingerdx v025 and I just have to do the things that you've already explained?
Besides, is there anything else to do before I install the zip file?
It's the third time that I block my phone and miraculously restore it to the v022, so I'd prefer not to make another big mistake..
Hope my English is good, and thank you all

Yeah welcome and for your question have you tried using the search button and reading the rom thread? Not only did you revive an old useless thread, you also asked a very simple question.
I'm sorry for being hard but this is better then giving you answers and making you think you can be lazy and can ignore searching and reading.

^^^this
@madamemim: it's simple.
1. make a nandroid backup to be safe.
2. install cwm
3. dl the gdx (for stock) version you want save it on your sdcard
4. reboot to cmw
5. full wipe, clear cache, dalvik, etc.
6. flash your new rom
i'm assuming you know how to use cwm since you already flashed a custom rom.

[Q] Installing a ROM and Updating

Hey guys,
Sorry if this seems really noobish, but I seem be to kinda lost in all of this ROM'ing goodness.
I have read up on installing custom roms and plan on doing so but I have a couple of questions first before I take that last step (already unlocked and rooted on my One) - note: I have read through the guides but I still seem a little confused as to what exactly changes.
I notice that all tuts mention that you will lose all data on your phone. Does this include installed apps or are we just talking system files needed for the new rom? I have my phone setup already and have my apps backing up with Helium (Carbon) but this is something I seem to be a little confused with
Secondly, using something like CWM (Premium), can I update my ROM quickly and easily without losing any data?
I know that unlocking my bootloader will not get me OTA's so I am looking forward to using many of the awesome ROMs here on the site!

1) When you flash a rom, you need to do a full wipe in aroma.
Full wipe will erase all but not the sd, so your app in home, your background, your account will be erased.
2) You can upgrade your rom with CWM if is the same rom and the base isn't different.
If the base is different you have to do a full wipe.

One more
How likely is base to change for a ROM package? And if I have to flash that new ROM package instead of doing the update through CWM, am I back at square one again with my apps and data or is it just updating what it needs to?
Thanks again for the help!

Then:
Now, all the rom is based on 1.29.401.13.
When it will change (it depens from htc) and you will flash the latest update of rom, you have to do a full wipe, and you will lose all file, settings and other.
Instead, if you have to flash an update like: you're on 2.5 to 2.6, you can flash the rom with only dalvik cache and cache wipe.
But it depens, you always have to read in thread rom

I guess its not so big of a deal considering I can backup most of my apps using Helium and the rest of the apps can just be redownloaded if I keep a list. Configurations should be backed up anyways.
Thanks for the help!

If you're rooted and you will restore your app after a full wipe, i advise you titanium backup.
With this you can do a flashable zip with all your apps and data

Thanks!
I will take a look at Titanium backup and see what it can do! It would only make sense that someone would invent a way to backup all your apps and data (no matter what) to be able to restore them after a ROM update that wipes the phone completely!

Titanium backup can do this
However, only data app, not system app.
If you backupping system app too, you can have issue with new update of rom
