Hi,
This is a router having U-Boot bootloader
https://openwrt.org/toh/zte/zxv10h201l
There are no information on how to boot using tftp method.
Already tried some boot methods using reset button with no result.
Any special info about flashing this model except from general flashing info?
U-Boot, simple (as manipulating a booatloader can be, I suppose).
For the manual, see: https://www.denx.de/wiki/DULG/Manual
You should be able to boot the BIN, then flash sysupgrade permanently via the web GUI. You may also want to update the Wiki after you succeed.
An example using Meraki MX60 (which also uses U-Boot): https://openwrt.org/toh/meraki/mx60#flashing
I [really] hope this helps out.
(I suggest running printenv to backup/copy the config before changing anything.)
The manufacturer has stripped down the U-Boot and removed the needed tools to install another firmware. Especially,
there is no tftp command, so the bin file cannot be loaded to memory in order to boot into it. Without tftp, the commands bootp and rarpboot do not function either.
There is a httpd server command, which accepts a bin file through web GUI but it does not install it (it says something like "bad file type")
If someone could help !
Some info from the UART connection:

I have same device and same issue cant copy initramfs-kernel.bin to ram. I tried bootp and rarpboot but device automatically reboots and loads default firmware, so is there a way to boot initramfs-kernel.bin from ram ?
There is similar device homehub_v5a which has same problem with booting custom LEDE/OpenWrt firmware, we need to Enable UART boot by connecting boot_sel2 to GND to get
ROM VER: 1.1.4
CFG 04
UART
but I don't have and idea how to find boot_sel2 pad/connector on this device
I found bootsel0 and bootsel2 pads on PCB. Make jump wires like I draw it on image
for just short amount of time until you see CFG 04 on serial monitor, it would be best to use two buttons to just release them and then you can upload u-boot.asc.You should use instructions below to make u-boot
please use openwrt master
download https://www.kresin.me/files/add_zte_h201l.patch
cd into your openwrt directory
patch -p1 add_zte_h201l.patch
rm -rf tmp
make menuconfig and select all zte bootloader
make package/boot/uboot-lantiq/{clean,compile}
you should have the bootloader in bin/targets/lantiq/xway/
and use these instructions afterwords
