    Hi I’ve read your article about the upgrading of the uboot version on the networkspace v2 (http://www.arm-blog.com/update-uboot-on-the-networkspace-2/) I was wondering if your compiled u-boot image contains GPT support (>2TB disks), and if you would like to share it with me. I have a hard time compiling it myself and I’m afraid I will brick my device. Many thanks, Tjalling

      I’m not sure what you are trying to accomplish, neither do I support Juniper devices myself. My best bet is that you need to have the modem in bridge mode so that the SSG5 takes over the router parts and the modem itself is wel… just a modem.

      Juniper does have a excellent forum and documentation on that part, so you may want to try that out. Let me know if you succeed!

      Kind regards,

    Hi Langerak,

    First of all, I want to congratulate you for a great blog site. I noticed your article about an SRX100: https://www.arm-blog.com/reinstalling-juniper-srx100-corrupt-flash-via-cli/. Would it be possible if you can share me a copy of the firmware package you used? I badly need it. Please. Hoping to hear from you. Thanks.

    The SSL certificate of your website has been expired for some days now, maybe you would like to renew it (I see you are already using Let’s Encrypt).

      Thanks for letting me know, I forgot to renew it :(. Fixed now!

      Kind regards,

    You have a lot of info here, so thought I’d ask (“can’t hurt”) your opinion on unlocking the Surface RT. It’s a great tablet but MS dumped it even though it runs 8.1! You can’t install anything unless it’s in their store– which is basically empty for the RT. Your thoughts?
