[Nokia 3 Guides, News, & Discussion] darthkfc:
Had lots of problems with different software like SP flash tool and Nokia OST/OUT tool.

All above methods with other peoples guides didnt help me recovery my nokia as keeped getting device detecting issues and stuck at boot loader.

I tried all drivers and images and finally found a setup that works everytime that boots and runs without issue.

I had to download from the mega link the NE1-147 folder and extract all to another folder. (https://mega.nz/#F!1ENgnThL!FyL9uYCC3Dq-16elThKAPg).

Download OSTLAv6.1.2 and extract install OSTLA launcher and install all drivers.

Then uninstall the online updater tool ( yes you heard me ) BUT DONT UNINSTALL THE DRIVERS!!!.

Download from this person the OSTLA v6.0.4 ( https://xdaforums.com/nokia-8/development/nokia-8-official-firmware-links-updated-t3678487)

Also the Patch aswel.

Extract both to folders. run launcher from OSTLA folder you just extracted and install online updater tool v6.0.4- just close when installer finished.

Copy Patch launcher from extracted folder and put in C:\Program Files (x86)\OST LA and replace. Also delete the config file right below the launcher file you just copied and replaced.

Now make a shortcut of the launcher you just copied onto desk top.

Open the Launcher and select the NE!-147 nb0 file.

put phone into download fastboot mode by holding down and power button till you see fastboot mode in bottom left of screen and the rest of screen black.

you can also put phone from recovery mode in fastboot mode by holding down up and power and keep holding and still holding when you see phone will power off if buttons released, keep holding into you see android on screen and let go.

sometimes it may give you a dead android guy with the words no command. just keep hold of volume up and power for 4/5 seconds then release and press up and should bring you into recovery mode. once in recovery mode choose boot to bootloader.

if you phone dont want to turn on press and hold volume up/down together ( i hold the whole button down from the middle ) and power button together intill you feel a vibration then release.

Lastly try all methods above while having the usb in the port. if doesnt work try without it sorts its self out.

it will then say the phones connected click next.. ( if edit phone information is highlighted select it and wait for few minutes till a error comes up then press next).

your phone should go through 4/7 reboots depending on what was your original problem the software is fixing..

phone will reboot once says update completed.

Enjoy.

I must add this info may or may not have been provided to people before and all thanks go to the original makers of the content i take no credit for it.

the only thing i take credit for is finding the right software and drivers that work together once setup in the right way can fix your TA1020 Nokia 3 phone but with out the original sources i coudnt have made this possible so thank you. you helped me repair my phone.

lastly this way has not voided my warrenty at all on my device and i am getting official OTA updates.

Still waiting on TA-1020 Oreo/ installing the TA-1032 nokia 3s Oreo OTA was what killed this phone for be to begin with till i found the above fix.
