[Nokia 8 ROMs, Kernels, Recoveries, & Other Develop] ferramenta:
After one week of experimenting with installing this rom, NikGapps and recovery I finally found a setup that works for me.

OneWayGamer’s updated installation instructions are on page 7 comment #130.

Hold Vol- and Power-> Power Off

Hold Vol- and Plug USB-> Download mode

Hold Vol+ and Plug USB-> Recovery Mode

T-Virus is easier to be installed through Windows operative system, on the NOST app.

The rom, by default, installs itself automatically to the slot that is not active.

Recovery, twrp or orange fox, needs to be installed in a different slot then the rom.

fastboot getvar all

#to see the active slot

fastboot set_active a

#choose a or b

fastboot flash:raw boot <twrp.img>

#to install twrp for the first time.

While you are figuring things out you will probably have to change active slots often.

Most of the times it is easier you do this through the reboot menu in recovery.

If the recovery is not setup, use the fastboot commands and type them when the phone is in download mode.

You have to change the active slot to the slot you have the recovery on when you want to access twrp.

Restart the phone often and wipe dalvik often. I guess the format data part is only necessary if you are doing the install for the first time. You can do it whenever you want but if you are inexperienced like me it can make stuff stop working and you might have to start installing things from the beginning.

My phone was still in warranty. I decided to install a custom rom because gmaps and waze and gps and location service overall was not workjng properly, almost not working at all most of the times. I tried the conventional approach, by contacting Nokia’s support and trying many solutions on different forums and nothing worked. So I tried the new rom to see if something would improve.

My first install did not make things work because of one of two reasons.

A – I did not install NikGapps properly or

B – I installed a wrong version of NikGapps, meaning, a smaller version of NikGapps.

The first time I installed basic NikGapps. It's around 150mb

The second time I installed stock NikGapps. Which is a larger packet, around 700mb, with more google apps and other stuff in it.

Through the process I discovered I should not have let the rom run for the first time without having NikGapps installed.

Try to always use the reboot to recovery option in twrp or orangefox. Or use the power button + volume down option to force poweroff and stop the rom from booting up while you install NikGapps properly.

You have to install NikGapps, and magisk and all the other apps, on the same slot where the CrDroid rom was installed.

Install stock NikGapps or full if you use your phone daily like me.

I was thinking the GPS Antenna could be faulty, could be loose. If you think about this, this is very unlikely. All components are jammed pretty tightly inside the phone. Where could the antenna go? To a parallel universe?

Anyway, now, my GPS is working much better then it ever did.

Apparently updated google services are fundamental for all the apps and phone to work properly.

I hope this comment helps.

Many thanks to the developer and all contributors. This is important work.
