Is deeb data recovery possible on P20 with locked bootloader? - Huawei P20 Pro Questions & Answers

All data recovery apps & software requires "root access" in order to make deep data search.
My bootloader is locked.
Is it possible to gain root access just for the above scope?
e.g. is there any root method without flashing the phone that gives root access?

[Q] Re-lock after root, and keep root?

Hi all - I've read that in order to root it is necessary to unlock the bootloader and then root, but I've also read some threads where the bootloader can be re-locked. My question is whether I can still be rooted then, maybe with the use of OTA rootkeeper or some such. I haven't rooted yet (my prime uses would initially be for adblocking and wifi tether), but I'm thinking I will soon. However, I'd really like to be able to hold out until the 4.2/4.3 OTA comes out before flashing ROMS (need stable bluetooth in a bunch of areas, and want to wait and see if there are problems with that update in stock).
So, any way to be stock, re-locked and rooted?
Can't you just root using the normal method then flash stock recovery to remove "*** Tampered***" and then re-lock with fastboot? You're system partition wont be stock obviously because it will have the su binary. You're boot loader will say "*** Relocked ***" though. I'm thinking it might be possible to remove "*** Relocked ***" using JTAG if someone can find the area in memory where the history of unlocking is stored.
Unlock bootloader, flash custom recovery, use Aroma File manager to copy su to /system/bin and set permissions, reflash stock recovery, relock bootloader, install Superuser from play store. This should work but I haven't tried it.

[Q] Can root lead to unlocked bootloader?

Since root has been achieved will this aid in unlocking the bootloader? Did it ever happen with the S5?
Root and bootloader unlock are two very different things tbh. Just because we have root doesn't mean it'll help unlock bootloader. Only thing is that maybe the devs attention will be turned to BL now that they don't need to worry about root.

Ok, I didn't know if having greater access to the system would help with the bootloader issue. Thanks!
Finding root gives you elevated access to the file system. To get a customer recovery, the bootloader must be modified (which requires root to access). But, to modify our locked bootloader to put on a customer recovery, you'll needs it's encryption key. Without it, no changes can be made and the 'chain of trust' is broken and the phone won't boot.

Gain TempRoot w/ KingRoot.
Run Sunshine and let it do the tests it needs to do, then get a code for it to activate the license and it will unlock the BL & S-Off for ya.
After that, install TWRP with Flashify & run SU, letting it update and you should have PermaRoot then.

[Q] Re-locking the Bootloader after availing Root access is possible??

Dear all,
As far as my understanding goes, unlocking the bootloader will disable data encryption making the device less secure; will it then be possible to relock the bootloader after gaining root access, i.e. use a device with full root functionality with a locked bootloader??
Thank you!!
Cheers!
No, it won't disable data encryption unless you intentionally do it by doing "format data" in TWRP (or any other means with similar purpose).

Cerebrus Anti Thert

I have a question, I know if I root my device, modify a couple of things, unroot and relock the bootloader it will probably stop me from booting my device because it was tampered, the thing is, can I temporarily root the phone just to install Cerebrus then unroot it and lock the bootloader?
This would be killer because without the OEM Unlock option and with Cerebrus as a hidden system app, you have full on Anti theft which is what I want in the first place.
it most likely won't work and if if it did you will no longer receive OTAs
