[Nokia 3 Guides, News, & Discussion] arsalan j:
Before following guide check this:

If you never unlocked bootloader or you flashed Android 7.1.1 nb0 with locked bootloader, then you need to go back to Android 7.0, after that unlock then lock bootloader. If you want to update, use OTA, don't flash nb0 because it have stock LK inside.

Here is the explanation why:

The LK does all the checking down the secure boot chain prior to allowing the recovery or boot.img to boot.

If a device has been officially Unlocked then the LK should write (normally hidden) 1 bite identifiers to partitions like secro, misc, oem, etc etc (Depends on the OEM where and how) so when you flash a new ROM the new LK should still look for these bite's and if it see's them then it will allow the none stock .img's like twrp to boot normally.

So to sum up

1. Nokia made a huge screw up and the Nokia 3 is a totally insecure device like most of cheap MediaTek Chinese phone's out there.

2. The LK knows the bootloader was officially Unlocked before and therefore ignores the secure boot chain.

i really dont understood properly what shaboXD is trying to say here can any one explain.

and also look at the steps that i followed and where i got stuck after each progress.

1) Have Nokia 3 ta-1032 oreo (8.0.0)

2)unlocked bootloader got orange warning on starting( cant be trusted)

3)downloaded spflash tool and TWRP.img

4)loaded scatter file NE1-0-215H-MT6737M and replace DA_SWSEC_CRYPTO20.bin inside spflashtool

5)copied TWRP.img to folder so spflash tool recognizing it and rename TWRP.img to NE1-0-215H-00WW-recovery.img

6)got TWRP but nokia phone wont start only on fast boot loader TWRP was showing.

7)Tried to flash magisk but there was no magisk there.

(here i got stuck so tell me that do i have copy magisk.zip to phone downloads folder)

8) after getting stuck i flashed nokia 3 8.0.0 which on starting updated to 8.1.0

9)even after flashing firmware with OST Tools i was seeing orange screen of unlocked bootloader

10) i tried rooting again by using SPflashtools and following above step 4.

11)on first try red and on second try it gives yellow with tick successful.

12)but issue was mobile stuck and was not opening and on "pressing power button only once" it tries to boot but only boot sound and vibration happen s for 2 seconds which means boot is failing

and device does not even open and this happens in a loop it will fail to boot and then tries tries again and again.

13)tried to flash firmware again this time of 7.1.1 now device opens but without any orange screen warning so bootloader is locked but on going to developer options i see "OEM unlocking on and off" options available does it mean that i do not have to unlock bootloader any more.

so my questions are

A) first explain the above skaboXD has said which is confusing.

B)where to put magisk and magisk manager

C)on installing TWRP does nokia normal boot does not happen

D)the last question is if nokia 3 7.1.1 is giving me OEM unlocking on option so do i have unlock bootloader again and follow the guide.
