DATAPUISTOKEMISTI

This is updated version of my original post. I purchased additional modem that's externally identical to old one but had different serial port USB ID (USB\VID_12D1&PID_1442&MI_00) missing from earlier driver pack causing original instructions to fail. I have also included latest Stick-mode firmware 21.200.07.00.805 I've found and corrected some incorrect information on original post. Modern Huawei USB LTE modems can be used in two very different modes. Default is HiLink mode where it functions as router doing NAT and other nastiness much like more traditional 4G routers connected over WLAN or Ethernet. Unsurprisingly default mode is HiLink, but luckily it can be changed to Stick mode getting rid at least one layer of NAT and related issues. Actually there's also third mode which is subset of Stick, instead of native NCM interface it uses legacy PPP over emulated serial port. This can be sometimes useful with older routers with USB port but you won't be able ...

Trying to upgrade Huawei E367u-2 from old 11.810.09.00.00 to latest available 11.838.01.00.1131 ends up with error code 16. This one was easy to fix - flash first  11.810.09.33.00 and then to latest.

Sierra Wireless 319U is fairly decent USB 3G dongle that supports up to 42Mbit/s DC-HSPA+. However it has nasty tendency to randomly hang .

I recently found old decommissioned Wyse Z90D7 Windows Terminal. Old BIOS, messed up OS, etc. So exactly how do I update this thing without all those complex management systems and active Wyse support contract?

My B593s had ancient Sonera branded firmware that has DNS issues when IPv6 is active. At least IPv6 reverse queries stall causing long delays. There's some rumors going that Sonera provides updated firmware over-the-air, but I couldn't trigger update despite trying hard. Might be because I was using Elisa SIM card. Since Elisa does have fairly recent firmware available for download I thought why not use Elisa firmware instead - get IPv6 bug fixed, have correct operator settings as default and also future updates should work without extra hacks.

Server in question was HP Proliant DL320 G6 from 2010 without any firmware upgrades ever made. Those old versions have multiple known issues, both usability, stability and hardware component compatibility related. Downtime required to perform these steps will be around 3 hours.

Some time ago I purchased external 3TB USB 3.0 hard disks, TrekStor DataStation maxi light 3TB to be exact. It seem disk models and manufactures used by TrekStor vary, which is no surprise. Therefore I have externally identical disk enclosures with three different models of disks due making three separate purchases over few months.

After realizing that LSI SAS1078 based controller wouldn't do what I want I ended up purchasing card from eBay, 65€ including shipping for unused, new in box Dell PERC H310. Prices are bit higher than I like, but this was acceptable knowing it will do exactly what I need. Despite trying hard card will still show up as DELL after making these changes but it's in IT-mode and accepts generic LSI firmware.

I wanted to use Fujitsu OEM (D2516, "LSI Logic MegaRAID SAS PCI Express(TM) ROMB") of LSI MegaRAID 8708ELP in JBOD mode, which apparently is not possible . Out of MegaRAID products only 9240-4i and 9240-8i support true JBOD. Also 9260 and 9280 series can apparently do it via MegaCLI which is another beast to master. Rest of models can only do single disk RAID0 which isn't the same thing.

New HP LaserJets are like Windows PCs. Operating system is bloated and buggy. Recently I had to fix HP LaserJet 600 M602 that said "49.38.03 error, turn power off then on" each time you tried to access network settings via menu - and via ethernet it was completely dead. To fix this turn printer on, press (X) button when all three leds on front illuminate, login as admin, clean entire disk and reload firmware from USB stick.
