lost or deleted imei number



  • Hi folks,

    is it possible to recover your imei number for your phone as I can not make calls with my network provider? After reinstalling android i also have imei invalid warning. I installed ubuntu using the bq flash tool and I have also used the ubports installer. But I still can not get it to recognise making calls.

    My phone is bq Aquaris E4.5



  • @danieltheman
    If all else fails, BQ support,should help



  • Yes i have been in contact with them and they should phone me tomorrow! I hope they speak english!!



  • @danieltheman
    Cool
    I need to contact them to get my nvram fixed on my. M10 fhd ( pretty much the same thing)


  • Infrastructure

    @danieltheman Apparently you deleted the IMEI with the sp_flash tool. Happened to a few users already. Hopefully BQ can help you, there is no other way to get it back...

    BR



  • @flohack Yes that is the case bq have just returned a call from an email i sent them and have informed me of this... I would need to send my phone back to them!! Not sure if there is a cost involved as I had just woken up and in my dazed confused state I didn't ask for any other information on this regard.

    Perhaps I will phone them back and see what they say.

    Flohack, could you please shed a bit light on this issue. Would it help to write down the IMEI before and re-flash this?



  • One way deletion happens is, if you overwrite/format all partitions with the BQ flash tool (which somehow seems to be the default setting???) instead only upgrading the os.



  • This may come late, but deleted imeis can be restored quite simply in Android, hopefully in UB too in near future. I formatted them from my bq 4.5 an this is how i got them back. Should work with other phones too.

    Open dialer and type: * #* #13646633#* #* (NO SPACE between * and #, This forum makes them italic if written together)
    Click: Connectivity
    Click: CDS Information
    Click: Radio Information
    Click: Phone 1
    Type: AT +EGMR=1,7,"NEW IMEI1 HERE"
    Click: SEND AT COMMAND
    If OK was was reported, then go back and choose Phone 2 (If you have 2 sim phone)
    Type: AT +EGMR=1,10,"NEW IMEI2 HERE"

    After that reboot phone and sim should now work.

    IMEI numbers can be checked with dialler command: *#06#

    IMEI numbers can be found from sticker in phone or box or even from old phone. If imei from other phone is being used, then that phone should not be used at same time.



  • Since nearly the "epoch time" of UNIX (1970) there are tools, like cu, or other more sophisticated like kermit or hyperterminal which in principle do all the same: they connect your terminal application (i.e. keyboard and screen) with the serial port of some device, like /dev/cua00, and all you type is sent with the correct baudrate, parity, etc. to the RX line of the device's chip and what it responds on TX line is displayed in your terminal's screen. In the GOD™ I worked a lot with such apps to let dial a modem some number and login into the system.

    Do we have, or can we have, such application to connect to the modem of our UT devices and send down AT commands directly from, for example the terminal-app?

    This would allow us to save such issues in a few seconds and without further apps.

    (GOD™ = Good Old Days)



  • @guru
    cu is in the package repository

    Interesting. How do I install this into my BQ E4.5 OTA3 and how do I connect this to the modem?



  • I can help you with the first part, but not with the second part, because I've never used it.

    # mount the root filesystem writable
    $ sudo mount -o remount,rw /
    # update the package list and install cu
    $ sudo apt update && sudo apt install cu
    # clear the package cache to free up space
    $ sudo apt-get clean
    # remount the root filesystem read-only
    $ sudo mount -o remount,ro /
    

    You should still be able to apply OTA updates, but you would have to repeat the above after each update.



  • I think, mounting the root device writable, is the most wrong idea. If there is no real app for this 'cu' it would be better to install it into a chroot'ed system.

    The access to the modem with 'cu' remains to solve.

    To each their own. I like to be able to have the commands I need immediately at my fingertips after starting the terminal app.

    But there is also the possibility of wrapping them in an app. I think someone did this for htop and some other commands in the OpenStore.

    The access to the modem with 'cu' remains to solve.

    Yeah... Anyone?
