OpenWrt 21.02.1 - Fritzbox 3370 - HW Subrevision 3 - Problems flashing

Installing and Using OpenWrt
1

Hi there,

i recently got a cheap Fritzbox 3370 with following data:

HWRevision 175
HWSubRevision 3
urlader-version 2186
NAND device: Manufacturer ID: 0x20, Chip ID: 0xdc (ST Micro NAND04GW3B2DN6), 512MiB, page size: 2048, OOB size: 64

According to https://lists.infradead.org/pipermail/lede-commits/2018-May/006874.html all HW-Subrevision >= 2 are supported.

I tried to flash latest OpenWRT according to https://openwrt.org/toh/avm/fritz.box.wlan.3370 with following output:

Unfortunately, the Box wont boot after reboot, the INFO-Led is blinking red. FTP-Server is still reachable, i can repeat the flashing-procedure with same result.

Did i miss something?

Kind regards and enjoy the holidays.

Edit 1: Pasted codelines of another (full) attempt, in the initially pasted lines i forgot " quote SETENV linux_fs_start 0".

Yes, you omitted one command. As per the instructions the active partition must be set to 0:
ftp> quote SETENV linux_fs_start 0

Ok, my fault, i posted the one of my attempts where i forgot to use thise command. I edited the initial post and added the output of the attempt i did before.

...initramfs-kernel.bin is the wrong image (part), initramfs is generally used to run OpenWrt in memory for testing and debugging, it is not intended for flashing.

You need to use ...squashfs-eva-kernel.bin for mtd1.

Sorry I did not catch this earlier.

Oh boy. Checked the lines again and again and using the wrong image for flashing again and again.

Thank you and nice holidays.

EDIT: Maybe a mod could change topic to "OpenWrt 21.02.1 - Fritzbox 3370 - HW Subrevision 3 - Problems flashing" - to avoid impression of non-working software. Thanks.
