The porting was easy enough - brilliant tutorial! - flashing with SP Flash Tool was successful as well.
However: when I boot up my phone after flashing, holding the "Vol -" button, it boots into "Factory Mode" (it always does that even with stock recovery). But adb works in Factory Mode, so I "adb reboot recovery" which... reboots it into nothing. I just get a black screen. And after a minute or two the system normally boots up. The next "adb reboot recovery" gives me the stock recovery. I tried with two different versions of K-50 TWRP, they gave me the same result.
So I am wondering, did the port actually go wrong somehow and this just means that TWRP I built was corrupted? Should I maybe try with a different one, for a different device? Or is it my device's fault? That it cannot boot into recovery before it gets overwritten by the stock one? Or is it something else entirely? Has anyone experienced a similar issue?
My bootloader is locked and I cannot unlock it via fastboot, since my "Vol +" does not work in fastboot for some reason (which seems to be a common problem on some phones) so maybe it's that? But from what I read SP Flash Tool should work regardless of the bootloader lock...
Any ideas?
Hi !
To test if your porting is ok,
please follow carefully the next steps :
1) Install the adb drivers and fastboot commands :
[Only registered and activated users can see links Click here to register]
2) Unrar the rar. Run “adb-setup.exe”. Hit “Y” to all 3 questions.
3) Tap on Settings --> About phone --> Tap Build number seven times.
Developer options --> OEM unlocking enabled and USB debugging enabled.
4) Download SuperSU.zip and BusyBox.zip at the next link :

5) Unrar the rar. Copy the two zips onto your microSD.
6) Plug your phone to PC via USB cable.
7) Allow the pop up request on your phone to give your PC USB debugging.
8) Open CMD (command prompt).
9) Type the next command :
adb reboot bootloader (and press enter)
10) Now type the next command :
fastboot oem unlock (and press enter)
11) Press volume up (into your phone) to confirm to unlock the bootloader.
You will see in the CMD prompt the next messages :
"Start unlock flow", and when it will be finished, you will see "OKAY".
12) Reboot in normal mode.
13) Be patient, when you unlock the bootloader, the phone reset to factory.
14) Now tap 7 times on Build number.
Then Developer options, and re-enable OEM unlocking and USB debugging.
15) Copy the TWRP (recovery.img) into the same folder of fastboot.exe and adb.exe ( c:\adb\ ).
16) Connect your phone to the PC via USB cable.
17) Open CMD (command prompt) and type the next command :
adb reboot bootloader (and press enter)
18) Now type the next command :
fastboot boot c:\adb\recovery.img (and press enter)
19)
VITAL :
keep the phone connect with pc by USB cable !
