Fairphone 2: Problem after update

Hello everybody,

first of all, I have a Fairphone 2. Yesterday or so, there was an update available for my Fairphone 2 so I decided to do it. The installation of the update took a bit of time but it went until completion. Unfortunately, the end of the update was concluded with a black screen and the android robot on the floor with the text “No command”.

In the Android recovery mode, I chose the following commands “Wipe data/factory reset” followed by the commande “Reboot system now”. The problem persisted. I tried to do a manual update using Windows but my laptop would not recognise the phone. I am now clueless on the next step, I guess I have no choice but send the device back to the company. Any other tips?

Best greetings,
Yann

Hi Yann and welcome to the community forum!

To make your Windows computer (I assume it’s Windows 10) recognize the phone in fastboot mode you can follow this tutorial: [HOWTO] Fairphone 3/3+ stuck in fastboot/bootloader mode with the Easy Installer on Windows - HOWTOs - /e/ community

It mentions FP3, /e/ and their easy-installer but the underlying driver problem affects all phone OSes and ways to install them.

Sounds similar to what I had - more info in this thread if it helps.

Hello Ingo, thanks for your quick and informative answer!

First of all, I have installed successfully the driver mentioned in the tutorial. I did an extra test with an older smartphone connected to the computer, the computer recognized without problem the smartphone. However, I was not so lucky with the Fairphone 2, it is still not recognized by the computer… Any tips on how to further proceed? Thanks for your help!

Have a nice week-end,
Yann

Is your phone in #dic:fastboot mode when you manually try to flash the system (or try to check if your phone is recognized)?

I think so. I chose the option “Reboot to bootload”. I then had access to a black screen with the printings “FAIRPHONE” + “POWERED BY ANDROID” and a blinking blue light.

I am seeing two other interesting options in the Android Recovery menu: 1) “Apply update from ADB” and 2) “Apply update from SD card”. Because my device is not recognized by the computer, I am kind of blocked to use the first option. How would work the second option?

You put the sd card in your computer, and copy the update file (I guess a *.zip file) on the sd card. Then you put it in your phone, start the recovery and update with this second option.
Hope this helps!

I will give it a try! Thanks for your help

First I need to find a way to transfer the update file on the microsd card. I was thinking to do it with my old phone but somehow I have big difficulties to connect it to different computers…

After a bit of effort, I managed to transfer the zip of the upload to the microSD card via another smartphone. I placed back the microSD card into my Fairphone 2. I then chose the option “Apply update from SD card” in the Android Recovery menu and selected the zip file. It started the installation but procuced the following error messages after a few seconds:
“(…) / E: footer is wrong / (…) / E: Signature verification failed /E: error: 21 / Installation aborted.” Any ideas on how to solve this?
Best greetings,
Yann

Sorry, non, I don’t know. Perhaps @AnotherElk has an idea?

Might be some driver conflict with the older phone then.
