There are two hardware versions, and for each, two different kinds of firmware.

So we have:

E3372s non-HiLink (PPP & NDIS)
E3372s HiLink (WebUI)
E3372h non-HiLink (PPP & NDIS)
E3372h HiLink (WebUI)

Then there are the region-specific revisions, like 153 for ours. Those specify
the frequencies where the stick works.

You can go between firmware kinds, so you could convert your non-HiLink key into
a HiLink one and viceversa. But the region code must match.

If you don't need advanced features like IPv6 or NAT avoidance, you might try
this way. But you can kill the stick if you flash the wrong file, so be careful...

You might want to try other values for the tx_max and/or min parameters. Always
remember to set the min back to the value you want, as it defaults to 512 every
time the max is changed.

Also, if you happen to enable the debug interface on your key, any message from
the firmware might help. But if I remember well, the steps to enable it on the
3372s are different than those for the 3372h, and a particular unlock code might
be necessary...

Best,
