Restarted today the NAS to try your advises and stuck in another boot loop... After executing kwboot and sending image to device, it starts booting and then:
Can't interrupt the process to enter any command.

Is that the same one being used in this thread before? If it is then it probably expected some envs to be set certain way, and then now the envs are not.

Before I build a different u-boot image for you to boot (our forum member ingmar_k has been rolling a new u-boot 2017.07 for this box).
How far did you get with the steps I've posted above? did you boot into Debian on USB?

Just to clarify - I'm starting kwboot from another linux server, being connected via USB2TTL cable
kwboot -t -B 115200 /dev/ttyUSB0 -b /home/downloads/u-boot.bin -p

egor.tio,
I think you need to power down and unplug for a few minutes, and then kwboot again with that u-boot.bin.
==========
However, here is a test u-boot for 2017.07. Run kwboot the same way you did before.
Please post the entire log here.

That will come after you can boot in to a working system. And then you can reflash flash mtd0 with a good copy.

Spent some time prepping USB with rootfs, was able to login to the Debian installer :-)
Don't want to reinstall it, so restarted again via kwboot and with magic command :
Forgot to save boot log, sorry.
How can I write proper env values to NAND, please? Or I should reflash it fully?

Again, this is not clear enough! which Debian system? stock or Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 ?

In each case above, I will need to see the boot log, and perhaps will ask follow up questions before I can recommend the next step (incorrectly assumption will cause problems).

Please forgive me for making wrong steps, I'm trying to follow your advises how I can understand them :-)
If booting from an USB drive is important step, please advise how to prep it, as uInitrd I found is from debian installer and after booting with kwboot and new uboot.bin you gave, I get Debian Install wizard starting.
For now I'm able to login in my Debian installed on a hard disk in NAS previously after stopping autoboot and issuing that magic command. That Debian is stock one I suppose, can I check that somehow?

I see. You are thinking Debian mainline installer.
The Debian rootfs can be created using Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 from my release thread:
https://forum.doozan.com/read.php?2,12096
It is a complete basic Debian system with kernel 5.2.9-kirkwood-tld-1. It has this box supported.
Once you logged into this Debian rootfs, it should show the correct mtd partitions. And that'll make flashing stock or new u-boot easier.
And something you mentioned above:
I did not quite understand the above. The log would be self explanatory.

Cool! the HDD is untouched when you boot with USB rootfs. But removing the hard drive is a good precaution.
Everything looks good. Except the mtd partitions look incorrect. This is the Zyxel 3xx NAS settings. So we need to adjust them.
Let's look back to previous boot logs to see what the original mtd partitions look like for this box and then we need to set it in serial console.
Let me read them again, and you can do the same.

By the way, this box can be run with Debian mainline, if you choose to do so. Some small tweaks need to be set up, though.

Before flashing stock u-boot image (compiled by yury_minsk), the mtdparts envs and /etc/fw_env.config must have correct values.
Here was how yury_minsk did the flashing with my instruction:

So there are a few items to do.

So I should boot from kwboot, stop autoboot, then
And then from Debian I should flash NAND as yuri_minsk did:
setenv mainlineLinux yes setenv load_uimage 'ext2load usb 0:1 0x800000 /boot/uImage' setenv load_initrd 'ext2load usb 0:1 0x2100000 /boot/uInitrd' setenv set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=orion_nand:0x180000@0(u-boot),0x20000@0x180000(u-boot-env),0x600000@0x200000(uImage),0x1000000@0x800000(minirootfs),0x6800000@0x1800000(jffs2) earlyprintk=serial' setenv bootcmd_exec 'usb start; run set_bootargs; run load_uimage; run load_initrd; bootm 0x800000 0x2100000' setenv bootcmd_stock 'nand read.e 0x1200000 0x200000 0x600000;nand read.e 0x2000000 0x800000 0x1000000;bootm 0x1200000 0x2000000' setenv bootcmd 'run bootcmd_exec; run bootcmd_stock; reset' boot
And then from Debian I should flash NAND as yuri_minsk did:

Not quite. Yury kwboot with stock uboot. The above envs would work only with stock uboot. You kwboot with new uboot so the envs are different.
I will be back tomorrow.

For stock u-boot.
1. Create flash-ready uboot
1. kwboot with uboot-netgear-rnd2.mtd0.kwb
2. Intrreupt u-boot and,
3. In Debian, check the mtds to make sure they look like this,
cat /proc/mtd
4. Fllash NAND as yuri_minsk did:

I'll be back for kwboot with new u-boot.

For new u-boot.
Prepare the rootfs Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 on USB. Note that we are going to boot with the new u-boot, so skip Step 4 (should not be done).
1. kwboot with uboot.2017.07-tld-2-rc1.readynas_duo_v2.mtd0.kwb
The u-boot log should show that there is CRC error for the envs.
2. Interrupt u-boot and,
and then
3. In Debian, check the mtds to make sure they look like this,
cat /proc/mtd
4. At this point, the mtd0 should be flashed with either stock u-boot or new u-boot.
If the goal is to run stock OS on NAND then flash stock u-boot.
4.1. Flashing stock u-boot
Create flash-ready uboot
Flash
4.2 Flashing new u-boot
More needed to be verified that the new u-boot can run stock OS on NAND. If the goal is to abandon stock OS then the new u-boot can be flashed without further investigation.
