  • E3276 bricked - how to unbrick


    I tried to upgrade firmware to my E3276 LTE modem

    Hardware ver. : CH1E3276SM
    Dashboard version : UTPS23.
    Chipset : HiSilicon
    SIM Lock status : unlocked
    Wrong codes entered : 0 (unlock attempts left : 10)

    I tried to put
    Firmware update started normaly, updated normaly, update give me result OK
    But after firmwre update, modem ist not recognized anymore!
    Not by router, not by win xp and not by win 7.
    Computer only find Huawei CD rom (not readable) when i plug modem to usb port. No other USB or COM ports.

    Green light blinking, if i put provider card into modem, light start from green blinking to blue (UMTS and LTE signal is found).

    How to unbrick this modem?
    Any way to fix?
    Please for help.

    Unfortunately but dc-unlocker does not have solution to repair devices that were damaged during firmware update process, check if it is possible to update back to original one.

        Then sorry, we won't be able to help in this situation. You might want to try to take it to local gsm shop to check it if it could be restored.

                  Sorry, wrong link, now itīs correct, forget my two older posts.
                  I tried this:
                  Install, then
                  download Hi Link Update:
                  Update, it returns with an error, but after this I was able to upgrade the firmware, I took Huawei E3276s-150 Swisscom from
        , now itīs back!
                  The Dashboard you can update too afterwards, here is a link for elisa dashboard,:
                  Never update any non hilink e 3276 dongle that has a firmware beginning with 21. to any firmware beginning with 22.
                  21. ... are non hilink,. 22. ... are hilink versions!

                      Hi, I live in Brazil, my 3276 is a 3276s-500 non hilink version, but you can upgrade firmware to any e3276 version as long as it is beginning with 21. for non hilink version.
                      Supported Frequencies DONīT change with firmware, I flashed on my 500 a 150 firmware and itīs still a 500 with supported frequencies of a 500 version (LTE Frequencies supported: B2 B4 B5 B7, UMTS: 850, 1900 2100)
                      Modem is fairly cheap here, can find it on (ebay brazil) for ~ 55 Us Dollars.
