Problem firmware upgrade SG3428X(UN) V1
Hello,
I recently upgraded my network with some new devices (SX3206HPP, OC300 and EAP773) but that's not the point.
So my core switch is a SG3428X V1 and I never was able to upgrade it with firmware found here :
https://www.tp-link.com/fr/support/download/tl-sg3428x/v1/#Firmware
I tried all firmwares, I never succeed to have any of them applied : I see the upgrade progress until 100%, I reboot the swith but the update never get applied.
I gave up with firmaware upgrade then...
Now I have upgraded my network with the devices I said before, escpecially the OC300, I was happy to see it wanted to upgrade my SG3428X(UN) V1 with 1.0.2 firmware to 1.30.
So I did the upgrade and... the switch never came back as connected on omada cloud, it says disconnected.
My network was working normally but I was not able to access to administration of the switch (which is a problem for me beacause of specific settings like LACP, QOS etc...).
I tried to reboot several times the switch, no effect.
I used a USB cable to reset the switch with putty : no effect... my switch still remain as non administrable (but working correctly)
I finally restore a backup with the usb cable console with putty and my switch came back.
I adopted it again on the OC300, made again the update, and same problem again.
I repeat this like 3 times, and always same problem.
I spent lot of time and effort (and money by the way) and now I have no clue how to upgrade my switch.... Shall I just give up ?
(I also found this post, the OP had same problem but no solution is given : https://community.tp-link.com/en/business/forum/topic/601790 )
Thank you in advance for answers.
