Router has boot loop after re-resting via reset button.
No idea is it a soft brick or considered as dead.
Followed this:
https://openwrt.org/docs/guide-user/troubleshooting/tftpserver
and this,
https://forum.openwrt.org/t/dlink-dir-853-a3-soft-bricked-after-padavan-software/197805/5
And this is what the result are, I don't see any Manu, looks aliens language.
Some thing with TFTP image loading problem or its dead now, can not be recovered?
Need guidance please
You have either bad serial connection, or have set the wrong speed/baudrate to the serial connection in putty
Edit:
Based on initial commit for that, the speed might be 57600
The layout for the pins is (VCC,RX,TX,GND). No need to connect the VCC.
the settings are:
Bps/Par/Bits : 57600 8N1
Yes It was speed issue, I changed to 57600.
But there is some confusion
https://forum.openwrt.org/t/dlink-dir-853-a3-soft-bricked-after-padavan-software/197805/5
Its said that: kernel == initramfs.
While, here https://openwrt.org/toh/d-link/dir-853_a1
is written " You should never flash images named xxx-initramfs-kernel.bin to the flash!"
Kindly guide me which option (1-9) and file I should choose.
Thanks for the prompt reply
Image1: OK Image2: OK
=================================================
Please choose the operation:
1: Load system code to SDRAM via TFTP.
2: Load system code then write to Flash via TFTP.
3: Boot system code via Flash (default).
4: Entr boot command line interface.
6: System Enter UBoot to Update Img or Bin.
7: Load Boot Loader code then write to Flash via Serial.
9: Load Boot Loader code then write to Flash via TFTP.

After loading "openwrt-24.10.0-rc7-ramips-mt7621-dlink_dir-853-a3-squashfs-factory.bin" still there is boot loop...
The option 1, image temporarily to RAM, likely requires the initramfs image.
Option 2, writing to flash, would likely need the factory image.
(I am not familiar with your router model, so this is just based on my generic OpenWrt knowledge)
Is this means, I should choose option-2?
You could download the initramfs image and test 1. That might help you to understand if the current OpenWrt works for your device, without writing anything to flash.
Thanks for guidance.
Uploaded kernal by using option-1, followed by updating through webui.
