華三 H3C Magic RC3000 電信定製版固件是否支持降級？

請教一下，有沒有人嚐試過將 H3C Magic RC3000 電信定製路由器的固件降級？目前固件版本功能受限，想刷回之前版本，但擔心有降級限製或安全校驗機製。有沒有可行的降級方法，或者哪幾個版本之間可以自由切換？如果有成功案例或教程，麻煩分享一下。weibo.com/ttarticle/p/show?id=2309405160209890017429weibo.com/ttarticle/p/show?id=2309405160211634847928weibo.com/ttarticle/p/show?id=2309405160211735511071weibo.com/ttarticle/p/show?id=2309405160210544066693weibo.com/ttarticle/p/show?id=2309405160211538378806weibo.com/ttarticle/p/show?id=2309405160210842124308weibo.com/ttarticle/p/show?id=2309405160209810325513weibo.com/ttarticle/p/show?id=2309405160210137481550weibo.com/ttarticle/p/show?id=2309405160209990680679weibo.com/ttarticle/p/show?id=2309405160209541890210weibo.com/ttarticle/p/show?id=2309405160211831980155weibo.com/ttarticle/p/show?id=2309405160210397265975weibo.com/ttarticle/p/show?id=2309405160210691129566weibo.com/ttarticle/p/show?id=2309405160210250727548weibo.com/ttarticle/p/show?id=2309405160210929942578weibo.com/ttarticle/p/show?id=2309405160209491296314weibo.com/ttarticle/p/show?id=2309405160210980536378weibo.com/ttarticle/p/show?id=2309405160209642291252weibo.com/ttarticle/p/show?id=2309405160210497929223weibo.com/ttarticle/p/show?id=2309405160209504141526weibo.com/ttarticle/p/show?id=2309405160209743216704weibo.com/ttarticle/p/show?id=2309405160210586009645weibo.com/ttarticle/p/show?id=2309405160210636603402weibo.com/ttarticle/p/show?id=2309405160210732810305weibo.com/ttarticle/p/show?id=2309405160211785842705weibo.com/ttarticle/p/show?id=2309405160210783404068weibo.com/ttarticle/p/show?id=2309405160211189989453weibo.com/ttarticle/p/show?id=2309405160210091343876weibo.com/ttarticle/p/show?id=2309405160209453809694weibo.com/ttarticle/p/show?id=2309405160210535678063weibo.com/ttarticle/p/show?id=2309405160211588710405weibo.com/ttarticle/p/show?id=2309405160210338545795weibo.com/ttarticle/p/show?id=2309405160210007457797weibo.com/ttarticle/p/show?id=2309405160210041012278weibo.com/ttarticle/p/show?id=2309405160210103926854weibo.com/ttarticle/p/show?id=2309405160209650942055weibo.com/ttarticle/p/show?id=2309405160211038994579weibo.com/ttarticle/p/show?id=2309405160209399283844weibo.com/ttarticle/p/show?id=2309405160209843879957weibo.com/ttarticle/p/show?id=2309405160211240583196weibo.com/ttarticle/p/show?id=2309405160209386701038weibo.com/ttarticle/p/show?id=2309405160210242338845weibo.com/ttarticle/p/show?id=2309405160209759994004weibo.com/ttarticle/p/show?id=2309405160210791792701weibo.com/ttarticle/p/show?id=2309405160210447859808weibo.com/ttarticle/p/show?id=2309405160210833473546weibo.com/ttarticle/p/show?id=2309405160210741461152weibo.com/ttarticle/p/show?id=2309405160209701273760weibo.com/ttarticle/p/show?id=2309405160210153996294weibo.com/ttarticle/p/show?id=2309405160210292670481weibo.com/ttarticle/p/show?id=2309405160210888261848weibo.com/ttarticle/p/show?id=2309405160211139657787weibo.com/ttarticle/p/show?id=2309405160210682740982weibo.com/ttarticle/p/show?id=2309405160211488047163weibo.com/ttarticle/p/show?id=2309405160209906532388weibo.com/ttarticle/p/show?id=2309405160210594660393weibo.com/ttarticle/p/show?id=2309405160210053333042weibo.com/ttarticle/p/show?id=2309405160211089326201weibo.com/ttarticle/p/show?id=2309405160210301059086weibo.com/ttarticle/p/show?id=2309405160210439209031weibo.com/ttarticle/p/show?id=2309405160211437715732weibo.com/ttarticle/p/show?id=2309405160209600348225weibo.com/ttarticle/p/show?id=2309405160210485608573weibo.com/ttarticle/p/show?id=2309405160209592221776weibo.com/ttarticle/p/show?id=2309405160211387383837weibo.com/ttarticle/p/show?id=2309405160210879611019weibo.com/ttarticle/p/show?id=2309405160209940086866weibo.com/ttarticle/p/show?id=2309405160210200395953weibo.com/ttarticle/p/show?id=2309405160210644729877weibo.com/ttarticle/p/show?id=2309405160210388877437weibo.com/ttarticle/p/show?id=2309405160211685179558weibo.com/ttarticle/p/show?id=2309405160211337052249weibo.com/ttarticle/p/show?id=2309405160209793548310weibo.com/ttarticle/p/show?id=2309405160209957126198weibo.com/ttarticle/p/show?id=2309405160210346934375weibo.com/ttarticle/p/show?id=2309405160209856462957weibo.com/ttarticle/p/show?id=2309405160211286458495weibo.com/ttarticle/p/show?id=2309405160209692622883weibo.com/ttarticle/p/show?id=2309405160210192007259weibo.com/ttarticle/p/show?id=2309405160209441226821weibo.com/ttarticle/p/show?id=2309405160209554473040
