saw someone posted this, any Guru can verify the steps? or make it clearer?

On the 5033T fastboot will flash only the system.img not the boot or recovery
image,so Magisk or TWRP cannot be flashed via fastboot. Also to flash via SPflashtool for the MT6739 you now need a custom DA and Auth file for that phone.
The downloaded edited 5033D system image will give you root access but install
RootCheckerBasic app to check as sometimes the root access disappears.
The phone modem is in the vendor.img partition and so should be unaltered as you
have flashed the system.img partition only.Your bands should be unaltered. Install the MTK Engineering Mode apk and use the bandmode function to see the bands. (Phone Developer option must be on(Tap build number untill developer options appear)).
Now that you have root access you can now network unlock the phone. Using ES File Explorer or Root Explorer. In the phone /vendor/protect_f/md you will see a file ST33_004. This file determines whether the phone is network locked.
If you get this file from an unlocked phone and put it in place of the one
in the locked phone the phone will be then unlocked and vice versa.
Download the 5033A firmware from the Needrom site. From the download get the protect1.img (in another files). Download to your PC the Ext4Unpacker tool.
Use the tool to extract the ST33_004 file from the 5033A protect1.img .
This is the unlocked ST33_004.
Using ES or Root Exp rename the existing ST33_004 in the phone as ST33_004bac
and copy the new ST33_004 file into the directory. The phone will now accept
non Telstra/Boost SIMs .
Also download the Mobile Upgrade S Gotu2 v5.3.5 tool to your PC. This is the TCL(i.e.=Alcatel) official firmware upgrade tool. It replaces the firmware in
your phone with the latest version on their server for your phone. For a stock
phone it will upgrade to their latest stock version.
For the 5033T+5033D 'hybrid' ,when started the tool appears to be downloading
the 5033T firmware from the server, so it seems that the tool could be used
to return the phone to stock, but this not tried or tested yet.
The Alcatel 5033T (Telstra) I have is Telstra-locked to the point that most online unlock-code providers can't get a code to free it up. The only places which say they can do it require you to bring it in (they're in other states) or they want you to install Teamviewer (!) and they'll do it remotely.
I'm sure this is a FAQ on other phone models, but I see nothing for the Alcatel 1 here yet. What are the chances someone with past experience on ADB can figure out how to get this working with a non-Telstra SIM?
