    UPDATE: the solution is by flashing the zip file named (Signed_Modem_3-4G.zip) through your custom recovery (I use TeamWin) .. the file is found here and you need to reply to the post with 10 chars reply to be enabled to download it

    ************************************************************************************************************

    Hello everyone, the S44 update did break the modem hack that was used to enable 3G/4G on some carriers -mine is China Unicom- and flashing the same modem file as before doesn't work anymore.
    after searching in the Chinese 1+ forum, I found a way to do that but can't totally get what is needed to be done. It says that I need to flash the files attached here but I'm so confused about whither I should flash the whole zip or just some files "did try to flash the modem file inside it but didn't work".

    Any help or tip or hint is so much appreciated. You can't imagine how bad it is living with Edge internet connection while your device supports 4G LTE !!! :(

    This is the chinese 1+ forum thread

    Oh maybe I didn't express the idea well. China Unicom and because of some policies has restrictions over OPO to use 3G/4G .. So we do what's called hacking the modem. It was so simple before, we just flash the modem with *****.bin file using fastboot and we get 3G or 4G back.
    But after the S44 update the procedure to crack the modem is different which I can't understand since I'm a noob.

    The international and the Chinese versions are completely identical. If I go outside China or use the second service provider here my OPO will work just fine .. the problem is in OnePlus as a company and China Unicom it sounds as they don't have an agreement or something.

    I'm not very used to Android (looking forward to my placed order :) )
    But with Samsungs etc. You can enable toggles through third party toggle apps. Try searching for those.

    Hello everyone,

    I have a noob question ¿Can I flash this .zip file to release this bands BC4 or AWS or BC7 and use 4G in my country? I have a Chinese version of OPO but I only use 3G.

    And I really would like to use 4G :(

    Thank you in advance.

    Hmmmm regarding this matter you have to check this thread in XDA
    http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031

    IF AND ONLY IF Oneplus supports these bands and your network does too but it has restrictions then sure you can by flashing the same zip file I did flash. If it doesn't work then I believe doing what the previous link of XDA says will solve the problem.
