Tozed ZLT X21 review aka Unicom VN007+

Sponsored Links
I am trying to figure that out currently. But i am bit confused about exact model.

A. I have VN007+ with 1.15.1 and it is clearly written at bottom of shell that model is VN007+

B. Now this is where i am seeking expert opinion from @All. At bottom of router, Model name is written as ZLT X21 (So it should be VN007) however when i log in as root, it shows "X21G"

Infact, have a look at system information page - attached side by side and most of important fields matches exactly.

So,

1. For my X21 (Right side of image), shall i use 1.15.1 firmware which is ideally for VN007+?
2. How do i ensure that i am not using wrong firmware to avoid bricking?

PS : I wont be able to tear down X21 at this stage to check exact chipset.
Faced some challenges but managed to change firmware to latest 1.15.1 with ADB superadmin. It is confirmed, VN007+ firmware can be used for ZLT X21 with below specifications.

Running at 50+ C without any cooling aid and WiFi is Off. With WiFi on, temp. goes up to 70+ C.

The SIM works in another device / phone ?
Power supply working? does it actually power on and you can log into it's web admin page? Not locked to any specific cell ID or network ?
 
Hi guys, I'm trying to access SHELL COMMAND Tozed ZLT X28
. I detected an open port and adb is connected to the modem, but when I send this command "ADB SHELL" to access the SHELL, the response is "error: device offline".

1. Is it possible to "ONLINE" an "OFFLINE Device"?
2. Do you know other ways to access SHELL COMMAND?

I have access to the Admin user, but I DO NOT have SuperAdmin user.
