V200R001B236D30SP00C00
of course, I changed the xex editor and popped up UPDATE FAIL and nothing too I tried updating B710C0UPDATE_V200R001B236D30DM09C11 and the same UPDATE FAIL also tried multicast no error crashes.
I have such a soft V200R001B270D25SP01C11 soft is from August 2015 ver.B SN: S2ZDW14417000442.
I have a similar problem, except in soft V200R001B270D25SP01C26. I also tried to upload probably all available versions of the software without effect. This "watchdog" is a rather different problem, because when you change the Cxx hexeditor we cannot calculate checksums. While some soft versions do not have a problem with this, the Scandinavian versions are protected. Similarly, there is no communication via SSH or telnet. For willing (Cyrillic) descriptions on 4PDA. In the Russians the topic was developmental, but there is no cash either.
Hello,
as for the "shortcomings" of WiFi - a colleague tried to replace the power supply with another one (maybe the current one can no longer bear the load)?
For counting FW checksums, I recommend looking at:
https://www.elektroda.pl/rtvforum/topic3292226 and download the attachment / guide -> there is how to calculate checksums using the free "HxD".
For the sake of accuracy, I closed that topic because of a lack of interest, however, that I have made enormous progress in disassembling the FW code of the entire B593 series of routers, I will soon present my application giving practically unlimited configuration options for this device
PS.
At the moment I can:
- Decrypt and modify configuration files
- Decrypt and modify ALL passwords (CLI and TELNET also

)
- Modify the router's "default configuration" (e.g., replace the password from the device distributor's "sticker" with a different one, etc.)
That's all soon.
GREETINGS
