Root without unlocking bootloader - Android Q&A, Help & Troubleshooting

Hello,
talking here just about ROOTING not flashing CUSTOM rom!
I have one simple question. Is it possible to root device without unlocking bootloader? I have mediatek CPU MTK6750T and stock ROM flashable via SP flash tool. What if I just add superSu manually to the stock image and flash ot via SP flash tool just over /system partition?
Or what If I just flashed recovery (TWRP, CWM) over recovery partition? Could I root from there as well?
In both methods I would NOT unlock bootloader right? So I could be rooted without unlocking bootloader?
Please explain me if something will not work.
Or can flashing original stock rom Lock bootloader again so nobody knows?
Thank you: )

Bootloader restricts rooting or flashing recovery, system or anything else.
Therefore, you can't do anything without unlocking bootloader.

But SP flash tool can flash directly to partition right? so what if i use stock rom and just change recovery image file to flash? So it will flash stock ROM with my Recovery img. I will turn of checksum of course..
Or does bootloader really forbid this?

Oh sry, I overlooked the SP Flashtool part. You can flash without unlocking bootloader.

I'm trying to flash twrp by changing the recovery file in the stock rom but I can't seem to find the stock recovery inside the zip folder.
thanks in advance

Reverting to Stock from Custom ROM

Guys , some people are reporting that they are unable to revert to stock rom after flashing custom rom.
If you want to save your phone , then i highly recommend you to make a complete backup before flshing stock rom
go to cwm recovery and select backup/restore then backup (it will make your stock rom backup)
whenever you want to revert , go again to clockworkmod recovery and select restore under, backup/restore option
now last and most important thing to run stock rom ---> flash stock kernel using fastboot method
first grab stock kernel to do that , download your phones stock firmware from here = http://forum.xda-developers.com/showthread.php?p=10885406#post10885406
using 7zip extract kernel.sin file from .ftf firmware file
connect your phone in fastboot mode and run this command
fastboot flash boot kernel.sin
I'm doing it again and again without any problem.. just be sure to flash stock kernel before flashing stock rom.
thanks, i will try this method too
first flash stock kernel , then using flashtool flash firmware , am i right ?
Stock kernel (kernel.sin) is included in the package (of official stock firmware). So everytime you flash an official stock firmware, kernel.sin is also flashed. No need to flash kernel.sin before flashing stock firmware. Correct me if im wrong.
I also think same , i tried that method by noooooob and it worked too

Install CWM without unlocking bootloader
You don't need to unlock the boot loader to install CWM.
Follow instructions here to root First

Install CWM using this tool

This is how I did it on my Ray
I always considered flashing with Wotanserver to be the best way to go back to stock. It basically takes care of everything. Sure, you'll have to root again afterwards, but that's not exactly very hard.
wotan server is also a good choice

download firmware which you have before installing custom rom, then flash it using flashtool.

No, you can flash CWM straightaway.
And don't forget, YOU CANNOT RUN CUSTOM KERNELS ON A LOCKED BOOTLOADER. YOU CAN ONLY RUN STOCK OR STOCK BASED ROMs.
say no to Drugs and ICS!

You can install CWM Recovery without unlocking bootloder but you have to root your phone first.
If you unlock your bootloader, you can flash any custom kernel which is built fir your device which will have CWM Recovery in it. i.e, you don't need to install CWM Recovery separately.
Once you have the CWM Recovery, you can install any custom ROM.
& don't worry, ROMs are built in large packages so that they're compatible with a number of devices. It doesn't mean that whole package will be copied as is to your root. Instead, you'll have some more free internal memory....

Happy Flashing!

tnx, so what do you recommend, unlock bootloader-----flash cwm-----and rom. Kernel and rom are in same file everything could be flashed from device, cwm ?
tnx again
First decide whether you want to unlock your bootloder or not. I recommend you to unlock your bootloder but it WILL void your warranty but you'll be able to do alot more than Locked Bootloder like using custom kernels & you'll be able to flash ANY available ROM built for your device.
So 2 options for you:
1. If you want Locked Bootloder:
Root Your Phone > Install CWM Recovery > Flash any stock based ROM using CWM Recovery.
2. If you want Unlocked Bootloder:
Unlock your Bootloder > Flash any Custom Kernel (Which is compatible with ROM you want to install) > Install the ROM using CWM Recovery.

[Q] Unlock Bootloader, Custom Recovery and Root

Hey guys,
I am trying to prepare my Nexus 9 to receive root (when that happens) and I was wondering if unlocking the bootloader will suffice for the time being? That means it will wipe it once, and I can start using my Nexus 9 without worrying of wiping it in the future.
Then it means as soon as TWRP comes out with a version that supports Nexus 9 I just need to flash that (no need to wipe device) and then flash SuperSU (no wiping either)
Am I missing something here?
You're right but...
Hey ombadboy
I think this will work. Don't forget to enable the oem unlock in the developer settings before. Otherwise your try to unlock will fail. Maybe you shouldn't flash the first versions of twrp, because this will be the first one for Lollipop und encrypted storage. Just boot the image once and flash superSU. So you will still get OTA updates.
After unlocking you should be able to root without losing your data twice.
After a few time and if there are no more OTAs in the near future you can flash a stable TWRP image.

See the guide here. http://www.theandroidsoul.com/unlock-bootloader-nexus-9/
Thanks for the replied guys. Yes, that's exactly what I did; now I have an unlocked bootloader.
So if I understood this well, can I get root without flashing a custom recovery? If so, what's the purpose of flashing one?

The purpose of having a custom recovery is to flash custom roms.
Here's some info for root

Recovery allows you to flash anything to device without doing manually with root explorer, adb or fastboot. Can do most anything you can do with recovery with these 3 tools.

DRM mysteries

HI guys,
After being a sammy boy for years, Sony's android development is still a deep forest for me with all its bootloaders and secret keys.
I've got a rooted 5.0.2 with twrp recovery and just read somewhere, that this is enough to flash a pre-rooted 5.1. Is this true? No unlocking of the BL nor putting the DRM keys at risk?
Have a nice day!
If the "pre-rooted" 5.1 zip is all stock and has stock kernel, then you're good to go. Custom kernel and custom ROM requires unlocking the bootloader.
All you have to do is, go on TWRP recovery, wipe everything and flash that "pre-rooted" STOCK zip WITHOUT exiting TWRP after the wipe.

So as long as the bootloader stays locked, my DRM keys are safe? And flashing a rom through recovery will not unlock a bootloader in any way?

Are you trying to flash through the stock or custom recovery?

The Stock.

It's not going to work through stock recovery. You won't be able to sign it the way you'd need.
If you're already rooted then you might look into Flashfire to install zips. I would make sure you have access to the original firmware and flashing tool to recover the phone if something goes wrong.
If you aren't rooted and the bootloader is unlocked then you might be able to build TWRP if it's not already available.
