Downgrade this 2.12.127 firmware ??

My Cloud OS 3 Personal & Network Attached Storage My Cloud EX4

Hello everyone.
I have access problems similar to the ones many of you comment on, and WD support does not solve them for me.
And they say that they will no longer generate new firmwares for My Cloud EX4
Although WD does not recommend it, someone downgraded this 2.12.127 firmware to the previous one: 2.11.178 which worked fine.

Please, if someone did, let them comment.
Thank

У меня тоже есть проблемы с доступом по мобильной сети. Я недавно обновил прошивку вручную ( 2.12.127 - > 2.12.127) на моем ex4, но ето не помогло. Также я не могу зайти на my cloud через Google Chrome потому что браузер отклоняет SSL сертификат от WD.
