Hi everyone, could anyone tell me a working method to downgrade from the LTE version ZYXELR13A02 - ZYXELR13A04 to the RG502QEA_R11A07-ZYXELR13A02 version? Thanks so much to anyone who can help me.

Could you please provide root/supervisor password for NR7101 with S/N: S220Z33013130? I tried with the tool but the one generated didn't work. Thank you.

is it possibile to revert?
-
I do not think it's due to firmware but to modem firmware. Before updating to latest modem module everything was good (device V10), after upgrading from a02 to a04 the problems started.
-
I suggest you to keep 13a02 modem firmware with V1.00(ABUV.10)C0.
-
for example, for me, speed decreased from 600Mbps to 50Mbps

Don’t do it!

also interested.

same here after last LTE firmware upgrade. Before this update I was on 600Mbps/100Mbps; after updating 50Mbps/70Mbps

Thank you so much. I'm on RG502QEAACR13A04M4G_ZYXEL version, what do you suggest?
-
so please someone can help providing a simple step BY step guide to revert to RG502QEAACR13A02M4G version? Thank you

Hello everyone. I updated to the new firmware and now I noticed a drastic drop in performance... in download it gives me back 50Mbps against the 600Mbps of before... does it also appear to you?
-
And so is there a way to update from RG502QEAAAR13A02M4G version? Thanks!

firmware that is broken and they aren’t able to fix… ridiculous.
