How to install Windows 10 on DigitalOcean?

Published on August 25th, 2018 under english, tutorials, cloud.

Updated for 2019: New link to download is here: https://files.kragujevic.tech/public/10.ENT.x64.EVAL.US-English.gz For whatever reason, DigitalOcean chooses not to offer it’s users the ability to run Windows on it’s virtual cloud platform. Many people, myself included, wish to run Windows in the Cloud, and find DigitalOcean’s services to be competitively priced, but until now, this was thought to be impossible. Thanks to good people at WhatUpTime.com, this is now possible! The system image we wi...

How to restore TP-Link MR-3420 V5 to factory firmware

Published on July 15th, 2018 under english, tutorials, networking.

If you’ve upgraded your TP-Link MR-3420 V5 to OpenWRT firmware, you might find that you can no longer flash back the original system firmware. Trying to flash the official firmware from TP-Link results in a “soft brick” (all lights light up and then WAN lights up orange and the router reboots). If you already have a soft-bricked router, re-flash OpenWRT using a TFTP server, like shown in my tutorial here. Log in to OpenWRT with SSH (192.168.1.1, user root, password empty or whatever you set) and...

Kako "izvući" PPP i SIP parametre iz ZTE H267N VDSL IAD modema

Published on May 11th, 2018 under serbian, tutorials, networking.

Ako želite da koristite sopstveni modem, umesto ZTE H267N modema koji Telekom Srbija daje za korisnike BBTF linije sa VDSL-om, možete zatražiti od Telekoma da Vam izdaju podatke za SIP i PPP, ali to može potrajati i najverovatnije ćete morati da se odreknete nekih prava time što koristite sopstveni modem. Međutim, postoji lakši način, a to je da izvučete podatke iz svog modema. Potrebno je da priključite modem na telefonsku liniju, sačekate da skine konfiguraciju sa Telekomovog servera, i povež...

OpenVPN in 4MB - Or how I learned to stop worrying and love the TL-WR840N

Published on May 5th, 2018 under english, tutorials, networking.

I'm a big believer in privacy and don't want my ISP to collect data about my browsing. I have decided to setup an OpenVPN server on a DigitalOcean droplet for $5/mo (Get your own server here with $10 credit). However, for whatever reason, I wanted to set up the VPN on the router level, so that all my devices get it's benefits. The router I choose to do this is TP-Link's TL-WR840N V5, which only has 4 MB of Flash memory, but has 64 MB of RAM. The 4 MB of flash are a showstopper in most cases for...

Restoring a bricked TP-Link router with TFTP

Published on May 5th, 2018 under english, tutorials, networking.

If you accidentally brick (install wrong firmware or misconfigure) your TP-Link router (in this case a TP-Link TL-WR740N v5), you can easily restore it without UART access by utilizing the built in bootloader's recovery feature. This works by setting your computer's IP to 192.168.0.66 and then holding the Reset button while the router is turning on. It will pull the recovery image from TFTP and install it and then reboot. Resources Stock firmware for TL-WR740N v5 (or as a ZIP) TFTP daemon for W...

Introduction This guide will show you how to write a new IMEI to a Mediatek Android device quickly and easily, and without damaging the device!
