  1. Hello Zibri,
    please help me.
    I tried to unlock my:
    Sierra GPS MC8781 3G WWAN HSDPA GPS 7.2M
    PCI-E MINI, but the message "MEP locked" didn't
    disapear !
    I made the donate, your program says:
    checking, unlocking, upgrade firmware ... ?!
    Maybe i made a mistake ?
    Kind regards

  2. Yes.. you did... you need the newest possible firmware for mc8781 (you can use the USB 881 firmware since it's the same card)

  3. Can you provide the extended at command interface unlock code for MC8775 and if you can on what conditions

  4. @Александр: YES. I can. What do you need it for? Changin IMEI? ;)

    Drop me an email and we can discuss it.

  5. My EMAIL can be found at the top of the donation page.

  6. thank you! amazing work! had a couple hickups, had to update fw and after, run a file i found to kick my sierra mercury out of software mode. ran your program again and voila, unlocked! thanks again keep up the great work to keep OUR devices OURS!

  7. Hi, I have payed the doantion, but when I put the "Paypal Donation ID" in, then I get an Error (wininet error #18: (Unknown WININET error #18).

    What can I do now ?

  8. Wininet error #18 is not from my program but from a component it uses: in other words it means that the component is not compatible with ie8/ie9, you must use ie7. This is an old program that was tested with windows XP Sp3.

  9. To everyone: instead of complaining by e-mail, please READ and UNDERSTAND the instructions inside the zip file. And the comment before this one.

TP-LINK Configuration file encrypt and decrypt.

Here we go! TP-Link is another company that thinks that security by obscurity could ever work. If you "backup" the configuration from most TP-Link routers, you will get a .BIN file which is "encrypted". Use this utility below, to decrypt it (so you can edit it) and encrypt it again. Have fun.

Powerline Ethernet fun and secrets.

Many 200 Mb/s powerline adapters nowadays are based on the INTELLON 6300 chipset. Despite what can be thought looking at them, they are all using the same hardware and firmwares. I heard many people with Netgear XAV101 or Linksys PLK 200 or PLE 200 having problems after firmware updates and many other people with other brands having much more problems because of lack of support or configuration/upgrade utilities. So let me explain a few things I learnt studying them. Many of 200 Mb/s powerline ethernet adapters follow the "HomePlug AV" standard. (85 Mb adapters use HomePlug 1.0 standard which is completely different). This standard uses ethernet broadcast packets using the HomePlug AV protocol. The interesting thing is that their firmware is made of two different parts: a .PIB file (Parameter Information Block) and a .NVM file (the code itself). In the P.I.B. there are many interesting things: The branding (mac address, device name, etc) and the tone map. I test


Hello again! Many of you probably hate as I do CORS because it hinders the very nature of internet, which is SHARING. There are some services to circumvent this commercial  restriction, one of these is the famous "cors anywhere". So yesterday I decided to make my own and allow you to make your own in only 2 minutes. To do so you just need a cloudflare account (can be set up in 1 minute). The you can upload my worker on it and have your personal very fast cors proxy! So, enough talk, just head to: The is also a demo online at: Enjoy! Zibri
