You may try using sfos-upgrade.
Ideas how to transfer the RPM file to your phone:
- Try directly downloading it using
curl -LOwith additionally all certificate checks etc. switched off, see curl’s man page for these options. Maybe Openrepos still allows for downloading via HTTP, e.g.
http://openrepos.net/sites/default/files/packages/5928/sfos-upgrade-3.11.4-release4.noarch.rpm?
Caveat: Likely you are also unable to enable “developer mode”, hence no terminal app.
Idea: You may try inputting the aforementioned HTTP link into the Jolla Browser. - Download to your PC / Laptop and use
scp sfos-upgrade-3.11.4-release4.noarch.rpm nemo@<ip-addr>:
I wonder if that works without “developer mode”? - Use MTP or Bluetooth file transfer. If this fails repeatedly, try some more times with
.txtappended to the file-name; i.e. rename the downloaded file on your PC / Laptop fromsfos-upgrade-3.11.4-release4.noarch.rpmtosfos-upgrade-3.11.4-release4.noarch.rpm.txt. But do not miss to un-rename the file later (e.g. by using Jolla’s mini-filemanager inSettings→Storage→…) even though installing it may even work without that. - More, alternative methods for this file transfer are denoted here:

If you have transferred this file successfully onto your Jolla 1, enable “Allow for installing untrusted software” in the Settings.
Then try installing it:
- For method 3 (both, MTP and Bluetooth) and method 1 with the Jolla Browser, you should find the download listed in
Settings→Transfers, can tap on it to select it and then hitInstallin the top pulley menu. - For all other cases you have to locate the transferred RPM file by using Jolla’s mini-filemanager (usually in the home directory of
nemoor theDownloadsdirectory there), select it there and then hitInstallin the top pulley menu.
If all that fails, one can potentially achieve something by using the recovery console, but for that you should really know Linux (sysadmin work) very well, and have or acquire knowledge about some specifics of SailfishOS.
After that: Do search this (aka “FSO”, e.g. here) and the original forum (together.jolla.com aka “TJC”) thoroughly, similar threads do already exist!
