[Q] Can I flash 2.3.5 with CWM without data loss?

For some reason I find mixed answers to this simple question:
I have CWMv4.0.1.4, I rooted with Ace Hack Kit months ago. I am currently running 2.3.3. I would like to update to a ROM with 2.3.5, is there any way to do this without data loss?
Some people seem to say if you use CWM update from SD card option, you don't lose data, other people emphatically answer YES YOU ALWAYS LOSE DATA ALWAYS. Which is it?
Thanks

The sdcard data will remain intact...the phone data can be kept but it is always best to do a full wipe to avoid bootloops or malfunctioning.
Just make a backup of your apps with titanium backup and restore it afterwards...also make a nandroid backup of your current rom just in case...

I also use SMS Backup+ to back up all my text messages to my Gmail account to be restored after I change ROMs.

[Q] Updating, not losing apps"Custom ROM."

I got my Note 10.1 a few months back. Now I have got a lot of apps that I love and don't want to lose.
I am using a custom European ROM made by zedomax "HighonAndroid".
I've decided 2 days ago that I want to update my note to jelly bean.
My question is: How can I back up all my applications before wipe/data reset?
I really don't want to lose the apps nor the root.
Can anyone help me?

titanium backup, buy it. you'll use it all the time
You can make a flashable zip of your stuff. If you do this, I have only had good resaults of flashing it after rebooting into the new rom and then flash the update zip. also would be good if you went ahead and did the thing in your securty setting to allow the non play store apps, especially if you have them.
This usually does a great job of doing the data part of the apps like logins and stuff. sometimes mine dont work right at first but it still saves a lot of time
If the rom you are going to doesnt have root built into it, which I think all here do, then getting root back isnt hard and there is this voodoo root keeper app as well somewhere maybe on the market. but rerooting isnt that big of a deal and shouldnt be nesesary

Ty very informative, but I don't think the root will be installed because im going for stock JB.
Only question is can I flash in germany's ROM when I'm on European now?

Yep, ODIN or mobile ODIN will do it... You would benefit from backing up internal sd card - connect to pc and copy contents of phone/internal.... This means if it does an entire wipe you don't loose all your game saves etc.... Not likely to but the chance is always there, especially if you use mobile ODIN and tick "clear cache/data"...
Though I am curious why you don't flash the stock UK JB rom in developement as all are the same, just csc is different...

I have up and I believe darkman_rs does as well, stock versions of the jelly bean set up to run on an 8013. Mine is for the uk and I think darkman has the nordik. Either will work. I am in the U.S. and use the uk version with no issues. The csc is consumer region stuff, both of these roms have that stuff taken care of so they will not have an issue in any region.
So if you are on a custom rom and want to go to a complete stock, then go to sammobile, firmware, download one from there and flash through odin, then reroot
Or you can grab another stock, or custom rom from here set to flash through cwm and go that route

If you are coming from ICS then yes, a complete wipe of everything is reconremended. If you do not do a full wipe and get FC, then you need to do a full wipe

Please advise
Thanks a million!!!

No man, if it doesn't ask you to do the factory reset than don't do it.
It recommended but why make more work to backup and restore all of your data?
If you updated via Mobile Support Tool than all of your data and apps should be there so just continue using your phone and enjoy...

[Q] Cyanogenmod 11 on 19305t

I have a Galaxy s3 i9305t (australian version) with cyanogenmod 10.1 installed on it. I see there is now CM 11 for the i9305. My question is, can I install the later version "over the top" of my existing version without selecting wipe data / factory reset so I can keep my apps and settings as they are now or would it be better to wipe data / factory reset before I started and put my apps back on after?
Thanks in advance for any help or suggestions.

There should be an option within the ROM for installing updates if I remember CM correctly, however I would always recommend backing any data up with a nandroid backup. Apps should also be backed up using titanium backup and any other data via windows transfer before any upgrade.
Also when changing versions of ROMs eg CM10 to CM11 I would suggest using the advice above, then wipe data /factory reset and cache wipe before installing the ROM to prevent bugs and issues as I have always had issues when not wiping but the good news is you can restore your apps from the titanium backup

Thanks

No problem, hope it works

Sorry for late reply. Nope still didnt work. I have tried it numerous times and even downloaded the file again in case something was wrong with my download. Each time I try to install it fails. I have got 10.1.3 up and running again, so I think I will stick with that as it is working very well. Thank you very muck for your help and suggestions.

Downgrade from lollipop without losing data

Hi everyone
I received an update notification a couple of days ago and updated my oneplus one to lollipop. however I really don't like it, it messed up with many of of settings(taskers,profiles settings etc) and I want to downgrade now back to how it was before.
I didn't backup before updating, is it possible to downgrade without losing data?
thank you

Yes you can downgrade without losing internal storage data only!
All apps with it's data will be lost
I followed this guide for that :: https://forums.oneplus.net/threads/guide-how-to-revert-back-to-cm11s-from-oxygen-guide.290605/
This will work only if you have unlocked bootloader and you are on TWRP recovery(As I tested on it and this works for CMOS12 or any other lollipop based ROM too)

thank you for the reply. Losing apps data it's a problem then, I have apps with data,configurations,settings etc and if downgrading ends up resetting them then it's a problem.

Do you have root? If not, root the device and then you can use Titanium Backup to backup all of your user apps (along with their data), then once you've reverted to KitKat you can root again and use Titanium to restore your apps.
