Is it possible to unlock the phone and flash only the kernel without wiping any data?
I would like to have benefits of the better performance from the new kernels but to not to have to reinstall everything.

From my knowledge, I don't think it's possible. An unlock requires a factory reset.

I think its not possible to unlock the phone without deleting data partition (for security reasons). How ever you can still backup all your apps+data with apps like Go Backup Pro(its free from market), but not sure if it will require rooting.
Other option: backup your data with adb pull/push commands
if you run out of options: try flashing unlocktoken from RUU mode(it avoids the warning screen, but I think it will still delete the data)
Well that is a shame.
I really wanted to make this as easy as possible.
You can try the app called carbon. Its free and does not require root. After the backup unlock the bootloader and restore the backup. Then you are able to flash different kernels.

I need to do a total backup of my Desire, as I have the Android Market problem, and I have tried everyrthing and I mean everything trying to fix it without having to do a factory reset. So please dont give me tips on how to fix it.
What I do need information on is how I can totaly backup my desire, meaning
contacts
sms
google maps starred loactions
and all downloaded apps with their settign are backed up
I am aware that there are things on the Android market that I can download to backup different bits at a time, but I cant use Android Market app to download anything so I need to get apps that I can put on the desire from my pc.
Any ideas would be very helpful.
My desire is running Android 2.2 and has not been rooted or modded in any way.

Titanium backup is not necessary - after rooting just use Nandroid backup from recovery.
Is there a way of backing up app data without rooting?
i.e. I want to be able to back up Angry Birds data so if I factory reset I can reinstall all my scores

yea, the APK is on the SD, but the data is on the phone - don't want to lose that after the hours I spent getting 3 stars on a lot of it... any suggestions?

Titanium Backup is a more flexible solution.
I don't see how backing up the whole nandroid and restoring it would fix anything, the phone would be in the exact same state.
Nothing that doesn't involve rooting to save data?
No way to do that. The data is simply saved in a partition that normal users can't access. So root is actually necessary in this case. Pretty easy and harmless, especially since you can unroot if you want to.
I thought so - I also assume to restore backups you'd need to be rooted too - silly - you'd think that some way to backup app data would be fairly common (to non-rooted bog standard users)...

Actually, I wouldnt call it exactly harmless. Depends on how you've gone about rooting it and what precautions you've taken.
If you're a newbie, ensure the following before you root:
Make a goldcard-Absolutely essential if you have an SLCD Desire, since RUUs are dificult to find for unrooting, if you're branded
Ensure that an RUU for your country is available, or a generic one which is sure to work.

There are apps to backup certain things like SMS and Application Installations (without data), which can work without being rooted. If you want the restoration to mimic the previous state of that app with data, then you need to access the system as root.
I backed up using Titanium backup after using unrevoked to root my device.
I now have a problem doing a OTA update from T-mobile/HTC (update 2.12.110.4)
It downloads then asks me to install to which I cay yes, it reboots and just sits at a screen. when I press the power button its shows the clockworkmod recovery v2.5.0.7
and says verfication signature failed and lets me reboot and doesnt install the update.
What is this?

OTA updates dont (usually) work after rooting. In most Rooted ROMs they wont download. In some they do, and wont update. OTA are like RUUs. They try to upgrade the factory version of the software and should be used only on non-rooted Desires. Anyway I dont see why you need them. In case you're rooted, the latest version of your custom ROMs would be better than OTAs..
How would I go back to the standard rom - is it by doing a factory reset?

If you mean you want to take your phone back to what it was when you first got it..This is called reverting to Stock
If you have rooted since you got the phone, and have not put on a custom ROM like Cyanogen, Aurax or LeeDroid, your phone is now basically Rooted Stock..In this case, if you just want to remove all the custom apps and data, you can do a factory reset..This does not remove the rooting. The app Superuser Manager will still be in your phone menu, and Recovery ROM-Clockworkmod/Amon Ra will still be on the phone. In brief, the rooting process is apparent to service engineers.
If you have put on a custom ROM like Cyanogen, Aurax or LeeDroid after rooting, if you just want to get your phone to the HTC look, you can flash a Stock based ROM-Froyo or Non Froyo (Just search for "Stock rooted ROM"). This will get you the HTC sense interface.
But if your purpose is to take phone back for warranty purpose and don't want them to know you've rooted it, you need to flash an RUU over your current setup. This will remove rooting process and get it back to factory setup.

So doing a factory reset wont remove the clockworkmod from my phone then?
How would I go about doing a RUU as I dont really need my phone rooted generally, and really only needed it for the Titanium backup?
Speaking of Titanium backup once I do the RUU I'm guessing I wont be able to restore my titanium backup bits, as I wont have root access anymore?

You just got your wish answered! Check out this thread. Apparently Titanium can be run in a Temporary Root mode, thus allowing us to restore items even after unrooting!
So doing a factory reset wont remove the clockworkmod from my phone then? No, it wont!
How would I go about doing a RUU as I dont really need my phone rooted generally, and really only needed it for the Titanium backup? How to Unroot If you want specific help on any step, you may ask freely. Just do a background readup by searching though, since there are a lot of guides here too.
I am not sure how installing a new custom ROM and kernel affects my device (R900x), but I already have root and unlocked the bootloader. Will I lose any of my data (music, contacts, etc.) if I flash DooM's Kernel and the FTS rom? And how should I backup data (preferably through CWM), even if installing a new kernel/ROM doesn't wipe everything?
The main reason I am doing this is because I constantly get software update reminders and I have to shut off my wifi/data in order to stop getting notified, because it will no longer let me click the "Remind Me Later" option.
Make a backup anyways
You wont lose data for kernel
but for Custom ROMS to be 100% functional i reccomend you make a backup and WIPE DATA
Thank you.
I also need help flashing FrAsErTag's FTS ROM. Can someone confirm these steps?
Backup data.
Flash UK-Generic firmware.
Factory reset data.
Get root. (Do I need to unlock bootloader and get root again after flashing the generic FW?)
Flash DooM's kernel.
Flash FTS ROM.
Run CDMA, Facebook, and gapps patches (CWR).
Restore data.
just do what the instructions tell you in his first post.
Well I'm not sure how to do it exactly, but I think I'm going to see if I can flash the full 2.3.3 update manually with FlashTool before I do anything else. I have an unlocked bootloader though, will manually flashing the update brick my phone? Thanks again for your help.
So the new update for AOKP http://aokp.co/index.php/releases/_/jb-build-2-r29 has pretty neat features. I am going to flash it to maximize my GNex's potential.
Just a noob question, I understand that flashing new ROMs will wipe my data. Can i restore all apps, apps settings, files on virtual SD like camera roll and downloads folder, as well as system settings simply by using Titanium Backup?
Would not want to risk all my data. Thanks.

If your bootloader is unlocked: yes, you can root (if you haven't done it already) and use TiB to backup apps + app data. Installing a ROM will not wipe your /sdcard. It's always a good idea to back it up though before a flash. Use TiB to restore apps + appdata to your new AOKP ROM. Be careful with system apps and settings, restoring such data can lead to issues.
If your bootloader is locked and you don't have root: not easily. Unlocking it will wipe your /sdcard, you need it unlocked to gain root, and you need root to use TiB. Your best bet in that case is this guide: http://forum.xda-developers.com/showthread.php?t=1420351. Follow the guide to gain root and restore the ADB backup. Then proceed with TiB and new ROM flash.

Thanks for the info. I forgot to mention that I am rooted and has an unlocked bootloader already.
Just one more question: people say to wipe data before switching to a new ROM (stock -> AOKP in my case).
- Will it be OK if I don't wipe? I don't really want to set all my system settings up again
- And will wiping data/factory reset erase everything in SD card?

You have to wipe or it simply won't work.
If you were going from an older version of AOKP to a newer version you wouldn't have to wipe; however, since you're coming from stock (a completely different ROM) data won't be compatible and you will have to wipe.
Note: not wiping will cause a bootloop.

Factory reset in a custom recovery will not touch your virtual sdcard.

Hey there!
I have a question? What's the best option for backing up my whole device? I want to flash CM 12.1 but I need TWRP for that, and for TWRP, I need to unlock my bootloader, which (according to people here) means to wipe my data and apps.
If I use the Backup app pre installed in my phone, will I be able to restore if say... I re-flash my stock ASUS ZenUI ROM again?

Yes you can restore from the backup using the stock Asus backup app if you decide to go back too stock. If you stick with cm12.1 then I would use titanium backup from the play store to backup and restore apps from a custom rom. However titanium backup also works with the stock rom but if it restores stock apps on a custom rom they will likely crash like mad.
Fun note when I unlocked my bootloader using the unofficial method it didn't wipe my data so I didn't need to restore any app backups. As always backup anything you might need just in case something goes wrong and you need to restore anything.
Pro tip, when doing backups on a phone like that zenfone 2 if you can backup to a removable sdcard cause if something goes wrong and you cant power on your phone you will always be able to access the backups using a sdcard reader.

Hi,
I recently tried a custom rom on my old phone and it worked pretty well. I liked the OS and now want to also do that on my current phone. But i do still have a few questions i hope you can help me with.
- Can i make a full backup of my phone (with app data) to my PC or maybe to my old phone? I am currently not rooted and tried helium backup but saw that sadly not all apps allow a backup.
- I know about titanium backup. Is there some way (if the above cant be done) i can root my phone without wiping the phone? So i can then use titanium backup to make a proper backup with data, then install the custom rom and after restore the apps+data.
In short: I hope i can somehow make a full backup with app data so i can install the custom rom and restore my app data again.
Looking forward to your replies.
Thanks in advance.
Nothing? No one ? =(
To root you need to unlock the bootloader, which wipes all user data. So you can't use root to backup your data. This is why I unlock the bootloader immediately after getting a phone.
You can try an adb backup though.

Thank you for your reply and thx for the tip. Ill be doing that too from now on when i get a phone.
As long as i can make a full backup with abd (with app data), Im fine with wiping to root it. But just wanted to make sure i can get app data back after the root process.
Do you happen to have a link to a proper backup using abd guide?
Thanks
no

Well with a few side searches i was able to open the cmd (admin), do a adb devices (which found a device) and then run the app + data command.
('adb backup -apk -shared -all -system -f C:\backup.ab')
I saw the screen on my phone to start it, which i did but it stays on Shared Storage (where before this mentioned the apk's that were being backed up). This is taking pretty long (as in hours). Is this normal or did something went wrong and is it stuck on that part?
Edit (Update): I stopped the whole thing and tried again. Now it finished in about 10 - 15 min. I did get a message "backup finished". However in the folder i gave up, there is nothing to see. folder is still empty
Edit2 (update): Found the backup.ab file. Apparently it was in a different folder i thought it would be. So if i then also make a copy of the internal storage and do this command, i should be good right? After doing that, unlock and root, i can use the 'adb restore C:\backup.ab' and have all apps + app data back as it was before the unlock/root ?
no

In a sense. Yes, but you might wanna read some threads about that first.. Otherwise. No one would wanna go back after unlocking his phone. Since restoring a backup from a locked phone on an unlocked phone can cause some issues.

I'm not really sure what you mean though.
If i unlock my phone with my code and then make the backup with adb and just in case, a copy of my internal storage, can't i use restore on the unlocked/rooted phone to have the apps + their data back and use them again ?
no
sm00th4f3 said:
No you can't. It will brick your device. The backup can only be used when your phone is still locked. So it is basically not needed at all.

So you are saying that there is no possibility to backup my apps+data, unlock/root/custom rom, and then restore my apps+data at all?
That was some what the question of my first post.
So its either, fully wipe with everything lost, then root etc. etc. or just keep it the way i have it now?
no
sm00th4f3 said:
The normal procedure is as follows:
After an unlock.- your data always gets formatted. So a backup is totally wasted time.
The backup isn't wasted time - if it is done after unlocking your phone, while it still has stock rom.
In case flashing goes wrong, make the backup while not having flashed twro etc at all.
You don't have to wipe anything if you just want root, since the phone will reset-wipe your data on its very own.
Just unlock it, let it reboot, Flash twrp, install root zip file. Reboot
In case of flashing a custom rom. Flash twrp, boot to twrp. Use the Reboot menu and reboot again into recovery
Reboot->Recovery (in twrp menu).
Then Wipe-> Factory Reset
Wipe-> Advanced Wipe-> Wipe System partition only
Wipe-> Advanced wipe-> select Data partition-> Change file system to ext4
Reboot Menu in TWRP->Recovery
Wipe Dalvik and Cache
Flash Rom
Flash Gapps if not stated otherwise in Instructions of Rom Thread
Flash Magisk or SUperSu , depends if you want root or not. If you don'T want encryption on older Roms, flash one of the two.
Encryption will later on be optional through Phone Security Options.
Wipe dalvik and cache.
Reboot.
Wait a bit.
Setup phone, done.

Yes but as you mentioned, unlocking means a full wipe. And i cant restore apps + their data from a stock phone backup to an unlocked phone as it can cause issues.
In my very first post i asked if i could make a backup of the apps + their data to restore them after unlocking/rooting/custom rom or whatever. Simple answer then is no.
So i either have to just wipe my phone and basically start all over, only unlock/root etc etc first.
Or just keep my phone stock like how it is now and just do nothing and wait until i get a new phone (which will be in a long time still)
