Hi everyone, I have a truble with Z8102 ax v2 The wifi would not work after I restored nand it will install uboot with no problem and flash firmware, but wifi fails to load. any idea why?

It can’t find the eeprom data from the calibration data partition

3

how i can restore it if it possible

4

Do you have a copy of it?
If so, write the data back to the partition.

5

unfortunately no I restord the boot loader via mtk uar and flashed the firmware everything works except the wifi tried installing the drivers no use :expressionless:

6

The missing data includes factory calibration for your individual device - it's often called the ART partition. There is no way to recover it and nowhere that you can download a 'generic' file.

Attempting to use a backup/dump of another device will not work properly -- since devices are calibrated individually. A mismatched file could cause your wifi to perform very poorly or even out of spec (including for regulatory compliance) -- or all of the above.

You've hit a dead end as a result of the lost data. The router can be used for wired purposes, but it can never be used as an AP again.

7

Isn't supported by Openwrt, is it ?

8

It's supported but you have to change the bootloader to v1 it can be done

9

thank you for the reply that's really bad but i learned something today

Something strange has happened. I flashed the official firmware and the wifi worked, but other firmware would not. any ideas?

Seems the statement isn't entirely accurate ...

12

yes i tried it dawnload rooter frimwere you will find a folder named serial recovery the instruction is there

13

rooter <> openwrt.

if you're using rooter, ask them for assistance.
the device is unsupported here.

It appears you are using firmware that is not from the official OpenWrt project.

When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.

You may find that the best options are:

  1. Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
  2. Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
  3. Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).

If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.

I found the device of the firmwere selector(openwrt) and installed it its working but no wifi also on rooter does not work . i will be using the official firmware for now until someting comes up thanks for the replays

16

that's not what your (now deleted) firmware URL said ...

anyway, best of luck.

17

yes i was thinking you wanted to try it at first sorry for misunderstanding
