[HowTo] [FP2] Update baseband & other firmware


  • Infrastructure

    Motivation
    The Fairphone 2 has got some interesting firmware updates that most users seem to have missed on Ubuntu Touch. While Android users can utilize the updater App made by Fairphone, Ubuntu Touch users are mostly stuck with the stock firmware that came with their device, which might be outdated. Support suggests to update firmware for battery stability and reboot issues. So I thought I give it a try.

    Note: My results are probably skewed since I also use 16.04 on this device, but I will flash another one with 15.04 to verify them

    My reboots have dropped, and the battery life has been extended. So I am seeking users that can confirm or disprove this.

    How

    1. Download the latest Android update package for Fairphone 2 to your PC: https://storage.googleapis.com/fairphone-updates/3c9e6339-28cc-498c-9fe5-89c8a9c3c9db/FP2-gms-18.03.1-ota-from-18.02.0.zip
    2. The zip file contains a "firmware" folder. We only need this, extract it to a location of your choice
    3. Connect your phone, developer mode must be enabled
    4. issue the following command: adb reboot bootloader - The phone will enter fastboot mode
    5. Open a shell at the location where you have extracted the firmware folder
    6. Issue the following commands exactly as stated:
      6.1. sudo fastboot flash modem NON-HLOS.bin
      6.2. sudo fastboot flash sbl1 sbl1.mbn
      6.3. sudo fastboot flash rpm rpm.mbn
      6.4. sudo fastboot flash tz tz.mbn
      6.5. sudo fastboot flash dbi sdi.mbn
      6.6. sudo fastboot flash aboot emmc_appsboot.mbn
      6.7. sudo fastboot reboot
    7. The phone will reboot normally

    That´s it - please report your success or not :)

  • Hey Florian, thanks for the heads-up!

    I followed the instructions on a windows 7 pc (don't think that matters, but there you go :-) ) and a Fairphone 2 running UT 15.04 devel r280

    flashing went smooth, phone is up and running. i will keep an eye on stability.

    i have been experiencing signal loss (take it out of my pocket, see an X on the signal indicator, unlock the phone, indicator jumps to at least a little signal. seems as though being in my pocket is enough to lose signal?) would this patch help with that too? lets wait and see...



  • Thank you @Flohack
    worked flawlessly on my (old) FP2 with 15.04 rc22 from ubuntu 16.04 PC
    The only thing I would reccomend is to add sudo before all 6.x commands



  • Thank you @Flohack
    I also did it on FP2 with 15.04 RC3, it then reboots and runs correctly.
    I will see then if there is some improvement.

    @Yougo I also experience the signal loss you mention (the X in the signal indicator).



  • After two days I observe significant energy savings. Very good!



  • Thanks @Flohack :)
    Just updated my FP2 and will report back in a few days as well!



  • Hi
    On my FP2 15.04 RC3,

    For energy saving, difficult to say, battery consumption varies so much with the use of the phone that I did not succeed to conclude for an improvement (at least this is not worst!).

    Here an example before the firmware update with only 4G (disabled when i take the picture, but enabled before) and no bluetooth, no wifi, no gps and few use of the phone
    0_1524087999606_screenshot20180410_224742714.png

    and an example after the firmware update:
    0_1524088102128_screenshot20180418_232333532.png

    For reboots, there was may be less reboots but I still observe ones. I have them when using navigator, another web application and switching or closing one of the app.

    In conclusion for me there was no regression and I did not observe obvious improvements, but this was not serious testing, this is more a user feeling.



  • I have to agree with @ublublu, it is hardly impossible to tell if it "performs" better or not, i managed to run close to 2 days without charging this week which had not happen for a while.
    But also experienced multiple reboots with the motherboard getting very hot as previoulsy (when browsing or high wireless traffic apparently)

    Just a note, the FP2 mobile baseband update was from "4437.1-FP2-0-07" to "4437.1-FP2-0-08" in my case, stable with no observation on that end so far



  • I'm trying to install the base baseband firmware and have hit a snag. Should I enter the first command in the computer terminal or the phone terminal? On the computer (which is an Ubuntu 16.04 machine), it gives me 'device not found' and on the phone it gives me 'command not found'.

    I know I am probably missing something very basic: I'm a long-time Ubuntu user but not very confident with the command line.

    Any pointers would be much appreciated.



  • @danceswithcats you have to type the commands in your computer. Also you probably need to install adb and fastboot tools.


  • Infrastructure

    Amending now the instructions:

    In case your adb does not find the FP2 make sure:

    • You enabled developer mode in the system settings
    • Your USB cable is ok

    You can also manually enter fastboot mode by pressing POWER and VOL DOWN simultaneously until the phone reboots. Check with sudo fastboot devices if its there :)



  • All done. Thank you again for your help. I'll report back as soon as I notice anything.



  • @advocatux Thanks, Advocatux. Florian very kindly guided me through my ignorance and it is done now. Appreciate the help.
