maemo leste for nokia n9 in 2021
 

Hello community! May I ask for help in writing a step-by-step instruction for the maemo leste firmware method on nokia n9? My search for answers to the questions was unsuccessful - I'm at a dead end! Here are a number of questions that I don't understand as a beginner:
1. Do you need to flash the native firmware or is it enough to flash zImage_2.6.32.54-openmode_l2fix?
2. What to sew first openmode or ubiboot?
3. Options for partitioning sfdisk? MOSLO? GParted? How to do it?
4. What is preinits.tar? What is this archive for?
And the last one to take the image itself here - https://maedevu.maemo.org/images/n9/20190315/? And which maemo-leste-1.0-armhf-n9-20190315.img.xz or maemo-leste-1.0-armhf-n9-20190315.tar.gz?
The instructions at https://leste.maemo.org/Nokia_N9 are not meant for beginners.
I would really appreciate your help!
