Android Public Security Bulletin for March 2018 (partial)
Please note: Due to missing platform vendor specific patches, the Android security patch level will remain December 1, 2017. Protecting our users is our top priority, and as this month’s software update addresses some important security issues, we have decided to not wait with releasing this month’s update. We are working closely with our platform vendor to address the remaining issues as quickly as possible.
Reading between the lines, I’d say the more relevant question is what’s Qualcomm’s schedule on those issues. But with contracts and business relationships being what they are, I’d be surprised if we hear more than:
For the first time ever, the update was not working. Instead, after reboot I save the famous open Android with a big exclamation mark and the word „Error“, nothing else. Then the phone rebooted and was still on version 18.02.
I started a second attempt later, to the same result. This time it seems it started installing, but then failed again. I am upgrading from Fairphone OS 18.02
Afaik at that point you are able to get into recovery and have a look at the detailed reasons (when you see the Android robot: hold the power button, then press the volume up to display the recovery mode).
Verifying current system…
System partition has unexpected contents
E:Error in /cache/fp_update_FP2-gms-18.03.1
I had Lineage OS installed before, but was is strange is that I completely reset the phone afterwards. Also, the special post 18.02 update installed without any issues.
I guess a manual of the 18.03 firmware would fix this. But I would like to find the cause. Evev tried a factory reset, which obviously did not help, since it leaves the system partition untouched.
I am running LOS 14.1 on my FP2. When I did the update to version 2018-03-14 yesterday my phone couln’t read the SD card anymore and asked me to format the card. I did not, instead I rebooted the phone and after that it was all o.k. again, with all data at the SD card.
In TWRP there’s an “Install” button, from there select the storage (Internal or SD card), select the modem file and Swipe to flash it, then reboot.
The modem drivers get installed somewhere separately from the OS, so your OS and data will not be touched.
It should be possible to install the file with the built-in recovery of Fairphone OS, too, but I never used that, perhaps somebody else can give the steps for this way.
I have the stock FP OS and try to update from 18.02.0 to 18.03.1
Twice in a row, I had an error after reboot, while the system was updating. Removing and reinserting the battery allowed me to reboot my phone, the update was not applied.
