i can choose option 1 from ram however the usual option 2 for flashing on the chip just gets overridden replacing it with option 3 and booting up normally
here is the example:
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.
9: Load Boot Loader code then write to Flash via TFTP.

2: System Load Linux Kernel then write to Flash via TFTP.
Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)

Well,from what I can see confirmation with Y is needed.
Another thing I can think of Is TFTP booting kernel0 image to RAM and having USB prepared for recovery so when it boots you already need to be pressing reset
prior to flashing pandorabox i just hit 2 and plugged in it would stop and allow me to press Y/N right now i hold 2 and it just reboots and when i let go of 2 it just reboots and picks 3.
i had this in the past due to using my raspberry back at the time as a serial adapter
i will use another serial adapter since i have 2 normal ones check the cables try again and let u know
i did flash stock using tftp and seems im getting a bootloop of this:

and furthermore wont it go into a complete brick after i try flashing kernel0?
that is what you have done right?
U-boot does not like checksum of stock image.
No,mine was bricked after I flashed LEDE image that I made for testing.
It just bootloops without giving me a chance to do anything.
i remember when i first had it and hooked up serial on stock the RX to the device was blocked..
seems i still can choose an option during the bootloader though..
so most probably it can only be fixed if oneday there comes a rom which fully supports this device and is meant for tftp flashing right?
i wonder if there is a .bin file for padavan.
from what i know padavan is flashed through ssh on prometheus.
it also changes partition layout, in my wild geuss maybe that is a way of saving it
it does but unfortunately i think it first requires SSH access and then it goes by the way of rebooting with USB recovery. it also has a backup and restore function of firmware however all demands SSH access if im not mistaking. currently the only thing im able to do is operate the bootloader, try flashing files on the device or loading them on ram.
im also not that experienced to have any more clues.
the only thing coming to my mind if a version intended for this device compatible with tftp flashing
my lack of experience also made me try booting up the lede ram image and after obtaining SSH access to try and restore the router through prometheus ssh however when booting a ram image the partitions cannot be found
That site does not work.
If you have already prepared an plugged usb into router.
Then if you load kernel over tftp you can use reset button to recover.
You can see in stock kernel bootlog when to press reset button
so the kernel0.bin from this backup also can be used for ram booting? just to be sure
going to try it out now
...
just tried it boots up in console and as u said after a bit it says "press reset button to enter usb recovery"
i did that but didnt keep it pressed for long i wonder if anyone can explain more about this proccess since normally it takes taking out the powerplug but in this case its on the devices ram.
should i keep pressing it?
because i dont want to interrupt it im waiting and all it does is show continuous dots
....
update:
turns out i had to press it immediate and keep it pressed until the orange led blinked as the usual way goes
Well,you actually dont need unplugging,you can reboot or in this case kernel loads automatically after loading over tftp.
When it starts booting you press and hold.reset because by the time when you see that kernel asks to press reset you dont have time to react.
