[Q] Will firmware update loose my data & apps? no root cant backup apps

I have a new (2weeks) samsung GT-I9003 which kies report a new firmware update & before doing that want me to take backup but it will only backup my contacts/sms etc. how do I backup my installed apps as I have not yet rooted my phone, I searched the forums & found a way to root but got to know that even rooting will loose my apps/data so what should I do first?
I need the following things
I am testing various apps to find the best ones which I will using long term so as of now lot of install/uninstall hapening, after few days once I settle I want to update new firmware but should I root before that or after updating to new firmware.
Does rooting remains rooted after new FW updates in future?
Once rooted I can install apps like Titanium, unrooted I can't use Titanium yet to back up my apps & its data so its a catch 22 situation for me & atleast once I will have to loose my apps data but this time I should do it once for all so I can streamline future updates.

Hope some one can answer this.

If you update with kies you wont loose anything, if you update custom roms(for the first time) you will loose your apps and data.

Thats a good news for me, so should I 1st update the firmware via kies then root it as 2nd step?

I took backup & then started the firmware update, it downloaded a small file showed 100% complete & then strangely it opened another windows & its now downloading a huge file of 400-500Mb...........is the firmware that big?
The downloading is going on past 10 mins on 1mbps connection.
Finally it gave error in mid way I assume that something happened & made the usb connection loss, I got these screen shots & the phone is now hung displaying "downloading do not turn off the target"
What should I do, need help?

Since i did not get any answer i took the battery out & then plugged in again the phone booted fine.
I now have rooted my phone, if i update the firmware will I need to root it again?

depends on the firmware, most custom roms have root already build in

[Q] VZW update and CWM

I'm running decrap 1.1...My phone automatically attempts to install the vzw update every day, usually around 5 AM. With CWM installed, it seems that when the phone reboots after the install, it prevents the upgrade from actually being put in place. In theory this is a good thing and prevents unwanted downloads. The problem is that it is preventing my alarm from working and I wake up every day with my phone in CWM recovery mode. Plus I was late to work today. So, I would actually like to try the vzw update and replace it with the revolt rom if I don't like it. Does anyone know where the VZW update gets stored so that I can flash it out of cwm? Any thoughts on this would be appreciated.

You will need to flash back to stock and remove root to have the update install, and then if you change your mind, you will need to downgrade to the old software before being able to root again.

Do NOT install the update if you want root and Revolt. Just flash Revolt or Home-Less as instructed in their threads, and you will be good to go!!!

[Q] How to downgrade to Kitkat from Lollipop without losing any data?

I'm using locked rooted Kitkat,
updated via Sony PC Companion without wiping anything
after the updating to lollipop, it charges so slow, even when it's turned off
I used all the chargers here.
I'm planning to go back to kitkat without losing any app data.
I have no recovery and not rooted in lollipop. What can I do?

Backup your data using Titanium Backup or something app like that, and copy your backup OUT from your phone.
You can't downgrade WITHOUT wipe internal storage, because Sony implement encryption by default, as Google recommended it for used in Android 5.0.x
You can try downgrade without wipe internal data, if you don't believe what I say xD

I believe in you, But it's just hard to backup my data esp using titanium backup because im not rooted.

I think your only option is to wait for a Root method for Lollipop that does not require a downgrade first so you can use Titanium again. I tried to keep Data last night when I downgraded in prep for a rootable re-upgrade, and it froze during boot. Trying again while wiping the Data partition worked flawlessly.
Honestly, unless there's something stuck in there that you absolutely can't do without, your best bet would be to just take the loss and format the Data along with your downgrade.

I was eager to wait for the root without wiping data on lollipop.
But last night I solved my problem, I uninstalled Xposed and the apps from Xposed.
My phone is not discharging so fast now.

hello guys ,, dev.
i have problem with downgrading lollipop to kitkat on sony c3 d2505 it stop on flashing looder and there is no blue light on phone led .... please help what to do ??

[Q] I357 Lollipop Interruption

Hello, I just today found out about the update to the Lollipop 5.0. I checked and attempted the download. It got all the way to the restart and install and then it stopped and instantly booted back up. It came up with the notification "Update Interrupted" or something very similar. I tried again after resetting the phone back to factory mode. It did the same thing. I have seen people have the problem of not enough storage but i had plenty. Especially after the factory reset. I know that this is an over wifi update and i am trying to understand why my phone isn't accepting it or why it isn't working. Thank you for any help you can offer.

If you have rooted or modified the system apps in any way then the update is going to fail. You have 2 options:
You can wipe your phone and start with a clean stock ROM; or
You can follow the guide to retain root on OC6. You don't have to be rooted for this method, but this method will allow you to update if you've modified your system.

My system has been rooted before but it no longer has root access.
When you say wipe and start with a fresh rom, isnt that also the same as resetting the device?

To explain a bit further, the way the update works is there's a program built into the OTA. This program checks the signature of all the system files on your phone against a database included in the OTA. If all the signatures match then the update will proceed, but if even 1 of the signatures doesn't match then the update will fail as you have experienced.
When you root your phone you are exploiting a weakness in some aspect of android that allows you to modify system files. Once you modify system files by rooting you change their signature. Even if you unroot, it is impossible to change the signatures back to what they originally were. This is the reason that even if you unroot the update will fail.
By resetting the device you are essentially deleting all the user apps and settings, the system files go virtually unchanged. So if you unroot, your signatures still don't match and when you factory reset the device the system files don't get touched so the signatures still won't match. The only thing you can do to get the signatures to match is to flash the NE3 full Odin package. This will completely wipe out our phone and install everything (the bootloaders, modems, system files, etc.) from scratch.
So like I said you have 2 options:
Follow the guide I linked to above; or
Flash the NE3 Odin package and take the OTA.
Either way you have to use Odin at some point.

Can't install system update after I unrooted on Moto G (2nd Generation)

I recently rooted my device, and want to install a system update. I unrooted my phone using superSU, and tried installing the update. It downloads, then restarts the phone. After 10 seconds, the phone restarts and it tells me that the download was unsucessful. I rooted my phone using mobileGO. I am thinking about doing a factory reset - will that remove any files preventing the update. I really want this update, and any help would be appreciated.
:fingers-crossed: Thanks.

I have never user Mobile Go. I don't know how it works but I think it disables OTA.
You can always flash the complete stock ROM (There is a tool in the dev's section) but you will loose everything.
A factory reset will not help because it will not delete any file in the root directory. OTA updates verifies all files while flashing.
Try redownloading the update first.
Then if you don't mind loosing everything, flash the complete stock ROM.
There may be an easier solution, but I don't know it...
Hope it helps

Thanks for the reply; I tried redownloading the update with no success. Would you still need root access to flash the stock ROM?

No
