What I need to backup to try a different custom ROM and how I can restore it?
Should I need to remove any screen unlock before backupping in order to be able to restore?
Thanks.
You should backup everything of your current rom for restore it in case your phone get bricked while flashing an incompatible rom or missing any step from the rom flashing procedure

Ty, could you be more specific among all options available in backup menu?
What about my question about disabling screen unlock?
Yes you must disable your screen lock in order to be decrypted

I'm currently stock, rooted, S-OFF, and TWRP recovery. I'm flashed to 3.06.651.6 firmware.
I still get the OTA notifications, and my goal is to install the latest OTA update (without RUU) so that I can preserve data. I've created a TWRP backup, but that's the extent of it.
Any help is appreciated.
Other background - I reverted back to 3.06.651.6 after flashing firmware 4.06.xxx because I could not boot normally after that or did not know how.
My bootloader says Tampered, relocked

Ok
I have never done an OTA or Ran an RUU personally.
To the best of my knowledge you will have to flash the stock recovery and a stock rom to be able to take the OTA.
Sidenote: You say you are re-locked...when you unlock again it's going to wipe your device.
Backup everything important to your PC then run the RUU stuff is gonna get wiped either way might as well use the RUU as it's a cleaner method.
You'll have to flash the 4.06 firmware I pointed you to from the other thread to get the required hboot.

Serious Q - Am I not On the stock ROM if I never switched ROMs?
But OK, s=you're saying if I were even able to get the stock revoery reloaded, and receive the OTA, but then if i try to unloack bootloader after that I won't be able to? Also serious Q - Do you have a link on performing a good nandroid backup?
Next - if I did run the RUU, how would i quickly restore my data - just using titanium backup? is that the quickest/only way?

If you never changed roms then yes you are on a stock rom.
To unlock the bootloader again you would use Htc Dev again(unless you still have your unlock token) and by doing so it will wipe your phone.
Only way to nandroid is to have a custom recovery which means unocking bootloader.
I personally don't use Titanium Backup so can't answer that...I backup my phone/sdcard to my PC at least once a month (copy and paste to a folder on my PC)
Hi, m8s!
I'm using the official .283 ROM at the moment. I'm root and have CWM. I wonder if I make a backup of my current ROM and unlock my phone's bootloader (hence I lose all my data), could I restore the backup after without re-locking the bootloader? If yes, should I restore just /data or could I make a complete restore?
Thanks in advance!
anyone?

If you would make a backup of your current ROM, that doesn't backup your TA-Partition (I think), you need to make its backup seperately
Hi,
i have an galaxy s5 sm-g900f unrooted (still on warranty)
Before I try a custom rom on it , I would like to backup the original firmware so i can restore it if something happen. I know some original firmwares are out there to download but I would trust my own one better.
I've searched a little bit but i just found some ways to back up just the data (App data +apks ....)
also i've found some method but they need to root the device first but i'm not sure the if i rooted my device and i backed up the firmware and when i restore it, it will be rooted or not.
does someone know a method to fully backup the firmware without root ?
Can't be done without custom recovery, which will void your warranty
The stock firmwares you don't trust, are identical to the one running on your phone right now
sammobile dot com & ODIN will restore stock
But if oyu are going to flash a custom ROM, then you'll need custom recovery anyway, and also void your warranty
Flash TWRP recovery, backup your ROM, flash what you want

Yea, It`ll be identical to how it was when you backed it up, (Speaking from TWRP full backup)
Hi,
I hope somebody is willing to help me; I couldn't find a guide covering exactly the same problem. Actually, I'm "just" looking for the right order of steps I should perform in order to restore the factory state of my Z3C. I'm currently running Cyanogen Mod 12.1 with unlocked bootloader (obviously). I would like to return to being able to use the DRM Camera functions. Afterwards I'd probably like to try another ROOTED stock-based firmware. (Thus the DRM functions should still be available again, right?)
Current setup: CM 12.1 + bootloader Unlocked + TA Backup has been performed
Aim: flash stock firmware + restore DRM functions + install (pre-rooted) stock-based firmware
What I don't understand: If I re-flash stock firmware the phone won't be rooted anymore, Custom Recovery is going to be lost, right? Is it right to T H E N restore the TA backup? (As the bootloader will be automatically relocked?) Or do I need to perform additional steps or the above mentioned in another order?!?!?
And: Can I then simply flash a stock-based ROM without losing the DRM functions again?
Thanks in advance!

You simply can not restore back to factory state of your phone unless you have backed up your DRM keys. I'm thinking that you haven't so...
Anyways, you can use a pre-rooted stock ROM and you will have stock state of the Z3C and also root. To do this, you simply download any of the many alternatives in xda. I, myself, recommend you to use Wajk's SlimROM. It has good features, good debloat and awesome battery life. You'll be on stock ROM and have root but you won't be able to use DRM functions. If you want the DRM functions so badly there's a way to spoof it. You can visit here: http://forum.xda-developers.com/z3-...ocked-update-conceptmm-root-recovery-t3291722 and follow the instructions. It will give you the concept version of Marshmallow, root and DRM functions!
The thing is you have lost your DRM functions by unlocking your bootloader. So flashing any other Stock ROM will not bring it back as it has something to do with the system of the phone. If you are OK with a Stock ROM without DRM functions, there are plenty Stock Pre-Rooted Firmwares on xda. You can download one, do a factory reset, and wipe dalvik/cache, then flash the Stock ROM.zip through your recovery. Have the best of luck!
EDIT: I don't know about the TA backup as I have never used it :/

Thanks for your effort! But you misunderstood me, I have a working backup of my "former" TA partition/DRM keys. All I was wondering about was WHEN exactly I should perform the restore process. But I found out anyway. For whoever should have the same question:
- revert back to the firmware you used when performing the ta/drm backup
- if necessary: root (as the ta-backup tool needs root permissions)
- restore drm key backup with the ta-backup tool
- do whatever ... I installed a pre-rooted stock based fw and it works with DRM keys and root/recovery

HI
Restoring TA backup Will NOT relock your Bootloader but it will simply restore the DRM keys that you backed up while unlocking Bootloader
So you will restore the DRM keys
flash stock Firmware
flash TWRP via fastboot and the you will be able to root with chainfire auto root flashable zip
or just download a prerooted stock firmware and flash it
The procedure to restore to stock rom on the internet is to flash official stock first.
Is it possible to restore from backup(backup stock rom before installing custom rom) on custom rom?
what need to backup if the answer is yes?

Not a good idea. You’re asking for troubles.
In theory: yes... You can make a backup in twrp, reatores It and lock bootloader. In real world: Just don't do that. There are several possible problems with It and people are bricking their phones doing a lot less...
