[Q] Can I update a custom rom without losing data? - Galaxy S III Q&A, Help & Troubleshooting

Hello,
Currently I have a Samsung Galaxy S III with the Android Revolution HD 9.0.0 and I want to upgrade to version 10.0.0 which is the current version (Both based on JB leaks).
But I don't want to wipe my data to upgrade.
The reason for this is because even though i've backed up everything using titanium backup, I have a layout which I like and lots of other settings for every app and I don't have a few hours to play with it.
Is this possible?
Thanks in advance

If you are currently running an ICS custom rom and the update is to a JB cumstom rom by the same maker then yes you still need to do a wipe.
But if you did a nandroid backup first before updating you could always try flashing the update without wiping but it could cause problems.
The devs always say to do a full wipe so that there are no problems
Hope this helped
P.S it is adviced not to make duplicate posts as Mods may close this one mate

[Q] Query on ROMS for P500 (to flash or not?)

Hey guys
I have a query from a friend who is in India (so indian ROM). Now he has a P500 with 2.2.1 android on it. He is visiting and asked me to upgrade the phone software after a year of usage. I feel the phone to be but sluggish. On connecting the official software upgrade it says V20 available or something like that BUT will wipe all data to do so. My friend is a noob and does not know much. He is pretty much set and forget. We were also looking at customs ROMS here. Now our questions are
1. Should I just upgrade via the LG software available?
2. How to backup and restore device after upgrade for this non rooted phone?
3. What is the latest android version provided by the update?
4. Should we go for stock / custom ROMS available here?
5. Which on is most stable with features?? He is pretty much set and forget.. Won't be able to troubleshoot and will possibly want all basic phone features working without (much) bugs.
More questions will trickle upon the answer of above queries
Ta
1. Not recommended
2. You'll have to root first, read this http://forum.xda-developers.com/showthread.php?t=803682
3. 2.3.3
4. You should go for the custom roms
5. Many available here on XDA
You should visit this thread by Bytecode which is answer to most of your queries:

I have rooted the phone via Gingerbreak and installed RA recovery 1.2
now
1) Which ROM is most stable out which I can install and forget.. I m currently thinking between 2.3.7 Oxygen and Cyanogenmod port?? any thoughts
2) How to backup the current apps / data and then restore on the new custom ROM?? Is it recommended??

Ra recoverry is outdated... I recommend that you instal rom manager and get CWM Recoverry.
About which rom you should flash....I highly suggest that you wait for andy's phoenix rom next release... it should come out soon

Is it coming out within 6 days?? My friend will not be with me after that.. what thread is it??
Any alternates can be suggested which is fast and stable with all basic features working..
Ta
cosmicxperia is a good choice
stable and good rom is miks cm7 no doubt, other roms are still in repair mode
I suggest you flash CM 6.5.8 (mik_os) first.
after 3 months, you will be sick and tired of it. So then you should flash Oxygen.
I hate CM
For apps you can use Titanium backup or just copy APK files from data/apps to SD.
For SMS and call logs there are software available in market.

Advice On Upgrading from ICS to JB with Omega ROM

Hi,
Apologies in advance for what is probably a very obvious question for those that know. I'm two days into my rooting experience and currently I have rooted my SG3 and then also installed the Omega v13 ROM. I haven't done anything with the kernel up to now.
My question is - when the official JB release happens (hopefully tomorrow) and I want to upgrade to it and then also install the new Omega v16 ROM, do I:
a) wipe everything, install the Samsung Official JB firmware and then install the Omega ROM again on top of it, OR
b) do I just wipe everything and install the Omega ROM directly.
I'm a little unsure of the difference between the firmware and the ROM (unless they're the same thing). Does the Omega ROM contain the actual firmware or is this a separate thing?
Any advice appreciated.
Thanks,
Adam.

Rom is usually the firmware but custom rom may not include the modem .
Uses existing modem .
You will need to root your phone before installing Omega or any custom rom .
Best is to wait for Omega build after the full release of JB then just flash that over current .
JB will not be released to all and sundry on day one it will start the rollout on day one and gradually work its way eventually to all phones .

Thanks jje. As I have already rooted and then installed a custom ROM over the official firmware, I thought it might be "better/cleaner" to do it from fresh. I have not great battery performance and still some redraw issues so I thought starting from scratch might be advisable. I would rather not though - I haven't' tried a restore from Titanium yet and not certain if it will recreate all my apps/widgets including their positions and data.
I'll wait for the release and then figure it out.
Adam.
Agree once JB is released and i decide on a rom it will be with a total wipe .
TB will create all apps but not layouts or folders organization .
A workaround is to install rom boot to recovery mounts and storage and format data .
Then go to your ICS Nandriod backup and advance restore data only will bring back layouts .
But you may find some apps FC or fail to open .

Trouble U/G Android 2.4 to 4.0

SOLVED: Thanks to ares05 I already got the rom I wanted! I didn't find that specific rom in the first place... Anyway, anyone googles for this same matter can use my thread as an Q&A. The only thing I did to get Neatrom Lite working was putting it on Internal SD (Without wiping data). And flashing it (choose zip from internal SD) from the custom CWM recovery, then reboot. (Yes for beginners, CWM is an requirement!). For Nexus layout lovers try regular Cyanogenmod, Trebuchet or MIUI. They are all great.

Hello,
Question to myself: did I researched, googled and watch the video upon registration?
Yes, but that doesn't solve my specific problem or provide enough information to try the risky situation.
Problems:
I have trouble upgrading from Android 2.3.5 to 4.0 through Odin3 v1.85. It's very unclear what Rom I need to get to flash.
I flashed through Odin3 Android 4.0 before, through reading a lot and accepted the try and ended up getting boot loops. So I flashed back my android 2.3.5 XWKJ5. that gave me CWM but also voided the possibility to upgrade through Samsung Kies what I regretted later.
Then I thought, Okay... I'll get the basic Custom Rom: Cyanogenmod 9.1 then, through wiping cache/factory and dalvik cache and flashing through zip file on SD card everything went great. But I was unhappy with CM9 because the playstore app didn't work anymore and I didn't liked the overall layout of the camera, apps and some other minor bug I found - I forgot... So I went back to Android 2.3.5 with nandroid backup.
Also I have ROM manager but that doesn't let me update the specific CWM 6.0.1.0 rom as it says "An error occurred while downloading your recovery." Probably more people have this?!
What I need to know to solve this matter:
I want the default (stock) android 4.0+ ICS firmware on my phone with root. Can someone provide me the exact link of the .tar/.tar.md5 file needed to upgrade my phone to that android version or higher if the rom is available for it (4.1.3?). Since I find it hard to search the correct rom needed to get this result. The rom you might provide me can be slightly modded but that's okay, as long as I have all the ICS features and the layout it naturally comes with.
All the current Phone specific data you might found useful in helping me:
Samsung Galaxy S2 (I-9100)*
Android 2.3.5
Gingerbread.XWKJ5
CF-Root 5 Kernel (Root, CWM, Superuser).
+Has made an Nandroid backup through recovery.
+Backed up my apps through Titanium Backup.
*It's no AT&T or T-Mobile version, luckily.
TL;DR: I WANT TO UPGRADE ANDROID 2.3.5 TO 4.0+, WHAT SPECIFIC ROM I NEED TO FLASH?
I hope someone good willing enough is there to help me and I will check this thread often for any replies,
Scy.
There are a bunch of ROMS here which will give you the stock ICS look and feel. I haven't tried all of them but if that's the kinda ROM you want then you could check out the ROM that I'm currently using, Neatrom Lite. Follow the link on my signature to the ROM thread. The latest version for Neatrom is 4.0.4 and you could download it from the link given on the first Page of the thread.
If you wanna try something else you check out the following links :

Take your pick.
Sent from a GT-I9100 having a mind of its own
Yeah, that's sort of what I want. The biggest reason of wanting to update is that my brother has stock ics 4.0 and his battery consumes like 50% less energy in locked mode(s), factor in the fact that his update cleaned a lot of the processes and unused apps. Also I am fond of the original stock look - especially the camera controls.
I will try neatrom (lite) later tonight I checked out the official forum Page, looks very very to my liking. I am so excited, thanks for showing will report later if it worked out.
- EDIT -
Yaaaay! Everything went flawlessly, it's cool that there is no Wipe needed as the forum thread indicates. I don't know if it works fluidly yet, but it seems everything is up and running like if it was original ICS. I think the Siyah kernel helps alot in battery usage which means alot to me because I travel alot. I will keep this rom for a long while if no bugs/freezes pop up! Seems so promising, thank you thank you thank you~~!!

[Q] A Connection Between Backup, Update And Rooting

I am new to xda forum and I want help from all experts especially from samsung galaxy ace s5830i experienced user.
I have recently bought this smartphone and I want to know in deep.
Like
Q.1 How Will I Backup My Android OS And Other Apps+Data?
Because I am new to this device and want to use some tricks and tweaks and for we should have backup so if something will go wrong, we will recover.
Q.2 How Will I Update My Device To Latest Android Version?
As this device comes with android version 2.3.6, and present is 4.2 or more. I don't know clearly. But everyone wants new things to try. So I want to update my smartphone.
Q.3 What Will I Get After Rooting Galaxy Ace s5830i?
While I was Googling, I got some articles of rooting. I don't understand it carefully. I want it to understand from different views. So, here I will get suggestion from different member with different knowledge.
What Is The Connection Between These Three Things?
When I was Googling, I found relation in these three things. Backup required rooted device like Titanium backup and other famous. Now, Update also require rooted device (Although I am not sure about this). Some rooting apps require android version above 4.0 but for this I have to update and for update I should backup and for this, it requires rooted device, as I have said above. Please! help me.
1. Use cwm to backup your device.
2. We don't have real 4.x
3. You can go deeper into the system after rooting and use root apps.
you can take backup of your system by clockworkmod recovery it takes backup of whole phone (system+apps)..if you want backup of your apps then there are many apps available on market for it..best one so far is titanium backup..
we currently have 2.3.6 version..don't expect official ics or jb update..i think we wont even get 2.3.7...anyway you can get ics or jb ui by any custom rom!!!!
rooting will help you run your phone at full potential with some tweaks and mods..
some apps works only on rooted devices such as titanium backup..
and from now on post in right section

if its 4.1.2 stock firmware than it doesn't need factory reset, but i have seen some users having a boot loop while doing so and to remove the boot loop issue they have to factory reset and wipe cache partition. it would be better if u backup everything before you do this(recommended)..
Backup evrythng using titanium backup or a similar app and restore the data after flashing the 4.3 rom..

Kies will have the 4.3 update when it is released for your phone .

The firmware hasn't been released yet for all carriers in all regions.
You could download it and flash it, thought.

Normally upgrade to a higher version should retain user data, apps & contacts. few weeks before i upgraded from 4.1.2 to 4.3 without loosing anything. But always backup the required data is suggested.

One word of advice: the i9300 4.3 update is VERY laggy and full of battery drain bugs. I would remain on 4.1.2 if I were you until Samsung releases a refreshed S3 update.
This is why the update may not be available through Kies, they pulled it as soon as UK users started complaining.
Regards,
Person who wishes he never pressed "install" on the 4.3 OTA...
