[Q] Back up the stock rom without wipeing it from the root process?

I just got my Nexus S. Before rooting it I wanted to take a back up of the stock rom. All the tutorials I have read for rooting use fastboot oem unlock which wipes it clean.
I did find another tutorial that roots the phone without wiping it, but in reality it still wipes the phone and just leaves the bootloader locked. Totally not what I want.
How do I back up the rom without rooting it...or how do I root the phone without wiping it so I can do a rom backup?

Distortedloops guide does not wipe anything.

Root stock tmobile us rom.

Is it possible to root it? I have unlocked the bootloader already. It's my understanding that falshing a custom recovery wipes my phone but I see no stock roms available. How can I root it with out wiping and if it must wipe, how do I back up my rom?

i dont think you'll wipe your phone with a custom recovery..i have rooted mine without wiping data..you can back up your phone using the custom recover first..

Follow the steps in the dev section in the unroot thread
you can use MyBackUp Pro before you root. But you can't keep all thru this process. Although not wiped, I would still bu sdcard before rooting.
flashing a recovery will not wipe phone--i recommend twrp
if easier to follow thread to unroot and flash cwr. do that. you can always flash twrp later
do a lot reading on all this first, so you have an idea of what/why of flashing steps

[Q] Bootloader unlock WITHOUT Factory reset?

Is there any method to unlock my bootloader WITHOUT doing a factory reset?
I like my phone how it is but am itching to try some other roms and see what else is out there - would be perfect if i could unlock BL, Install boot.img with CWM, then do a full rom dump so as I can just restore to EXACTLY how i like it should i feel the need to do so.
If no option to unlock without factory reset then is there another way to backup my phone in is current state and re-install when i want to?

Trying out Cyanogenmod

I've decided to give Cyanogenmod and therefore will need to unlocl BL.
If i backup via TWRP on stock, can i restore this when on Cyanogenmod if i decide to come back to stock?
Or would i need to relock bootloader etc?

You can run stock on an unlocked bootloader. Just ensure you backup the boot. Img a week and restore it if you want to go back

And be careful with CM, it has some problems with the sound.
Don't use a maximum volume, it might blow your speakers, and this is not a joke.
Otherwise, CM is a good ROM.

No i mean PROPERLY go back lol
Like Locked Bootloader, DRM keys restored etc.
Is this possible from a stock TWRP backup, or would i manually need to relock, restore TWRP, then restore TA partition?

no the twrp backup only does the rom it doesn't do any TA partition or anything like that, you would have to relock the bootloader on a stock kernel, restore the TA partition and flash a stock ftf file

TWRP without wipe?

So I just got a brand new Pixel 3, and my usual mistake is that I buy a new phone, install everything and then figure out that I need to root, and regret having installed everything. This time I tried to be smart and root using Magisk before I transfered my Google account. I screwed something up and soft bricked the phone. I was able to flash a factory image and get it up and running.
Long story short, my phone is working, and the bootloader remains unlocked.
With the bootloader already unlocked, if I try to flash TWRP, will I have to wipe again? I've tried to look this up, but most of the posts and other Google links I've found always include the bootloader unlock process.
I'd like to do this right away, but I'm hoping that TWRP doesn't wipe. If it does, it is what it is!
Thanks for answering.

Nope, you don't have to wipe anything to install twrp :good:

Backup with fastboot, unlock, restore. This should work...
