E173 updating firmware inserted is not firmware
Feel free to skip them and then start again from beginning when Mr Error #19 and Mrs. If you've tried this before coming to here I'm sure you've seen those "open Project Mode.html" instructions. You can get E3372h-153's from Ebay for 29€/each including shipping from Latvia.
Those are for older models like E3372s and won't work with E3372h. Your E3372h is now in stick mode, presents itself as NCM device that's compatible with Windows Mobile Broadband feature and also with huawei_cdc_ncm under Linux. This means to connect Internet use built in features of your operating system, stay away from "Mobile Partner" etc. :) If you don't root it someone else probably will given Huawei track record on security... Downside on these cheap ones is broken locking tabs on top cover.
Tried using different Tata Photon card (from a friend), still same issue. They were getting "Could not connect to the Internet" or similar error messages and were not able to connect to Internet. If a mobile phone or USB modem Internet works fine in one Windows version, why does it not work in another Windows version?
The reason is different features and functionality of different Windows versions.
There's excellent writeup and step-by-step instructions in English from Ivan. This is because they're LMT branded and were superglued shut with LMT SIM card inside.

The solution given in this tutorial will work in all Windows versions!
