@vugie, @nhedgehog thank you for valuable inputs.
To sum it up for other that might be reviving Touch Lux 3 / 626 hw revision PB626-1.9 without having original SD card.
HW revision 1.9 is using ELAN touch controller and this can be found on its LCD sticker

ED060XH7
U1-50
LET60G7004/(G120)
EJ8509C01R7A0113

Firstly create new SD card (sw_20160524_PB626_5.14.340.7z is only available firmware dump I'm aware of).

Highlights and addition to original guide:
- Before formatting first partition (mkfs -t vfat /dev/sde1) make sure you unplug and plug SD card to be sure that operating system will be working with latest partitioning table.
- At the end of the process plug in SD card once more and replace content of the first partition with content from 8gb.zip https://www.mobileread.com/forums/at...1&d=1620205846. Some files will be new, some are the same and some are different. I replaced all files just to be sure that i'm close to genuine firmware for PB626-1.9. sw_20160524_PB626_5.14.340.7z is probably from PB626-1.6 (4gb.zip is also from PB626-1.6 but contains more files it is newer).

8gb.zip contains default.wbf and waveform.wbf and those files matches 320_R069_AD8A01_ED060XH7U2_TC.wbf as pointed by @nhedgehog. Maybe they call it just waveform.wbf and not 20_R069_AD8A01_ED060XH7U2_TC.wbf because they are lazy or it was their latest and greatest screen before next HW revision so they did not named it properly.

Without using content from 8gb.zip the touch screen is not working.

It is possible to perform manual firmware update sw_20170718_626_W_5.14_1225_5.12_CI_gdb_pn_630_use r.zip. This update is the oldest still available package on pocket book support page.

I'm not heavy pocket book user thus i could not provide reliable feedback but all seems to be working correctly.
