  • BND-L21 unsupported security patch!

    After an interrupted update on an "Honor 7X BNL-L21 (originally BND-AL10)" touch screen stopped working.



    I cannot flash using DC-Phoenix neither unlocking the bootloader using HCU client (or even DC-Unlocker client)


    Is there a workaround?

    Can only try method 3 via testpoint maybe with loader + oeminfo.

      I cannot seem to find any 'board firmware' in the support area (DGTKS with and without test-point) just in case

          No thanks I'm using a dongle with an unlimited access.. Does it mean that I need to consider these files don't exist?

            I do not know about oeminfo file but loader should be available, depending on processor of your mobile.

              Thanks for your answer.. oeminfo and bootloader are available on DC-Phoenix,
              I was wondering about the existence of "factory firmware" (aka: board software) for this model (codename: bond)

                If you entered in search field on dc-phoenix "bond" word and no file that would include board software showed up then sadly, but this version does not have such file.
