My skywriter hat worked until there was some Hill something update notice. The firmware update did not seem to go well. Focal point of error: An invalid GestiIC Library was stored, or the last update failed The rest…any ideas? My error: ython [synth.py](http://synth.py) Got firmware info LL0:100.14;p:H Exception in thread Thread-1: Traceback (most recent call last): File “/usr/lib/python2.7/threading.py”, line 810, in \_\_bootstrap\_inner self.run() File “/usr/local/lib/python2.7/dist-packages/skywriter.py”, line 107, in run if self.todo() == False: File “/usr/local/lib/python2.7/dist-packages/skywriter.py”, line 336, in \_do\_poll handle\_firmware\_info(data) File “/usr/local/lib/python2.7/dist-packages/skywriter.py”, line 296, in handle\_firmware\_info raise Exception(“An invalid GestiIC Library was stored, or the last update failed”) Exception: An invalid GestiIC Library was stored, or the last update failed Populating temp PD file: /tmp/tmp3SmxXi Started PD with PID: 1525 File: /tmp/tmp3SmxXi Attempting to connect to PD Connected to PD ---

I’m not clear on what created your issue, a Pi software update or something else? Please, give us as much details as you can about the steps that lead to a working system leading where you are now. ---

I attached sky writer hat to pi zero w and installed software. [Test.py](http://Test.py) or [synth.py](http://synth.py) ran and returned position data along with the north,south or east west . Cannot remember which example…but it worked. I shutdown the pi at command line and went to sleep. Next day, after boot I ran [synth.py](http://synth.py) and got this sort of error: f I move my hand over or tap the sensor nothing happens, except the same stream of firmware info. Got firmware info 1.1.18;p:Hills Got firmware info 1.1.18;p:Hills Got firmware info 1.1.18;p:Hills So I followed the instruction to solve this from the thread and: git clone [https://github.com/pimoroni/skywriter-hat](https://github.com/pimoroni/skywriter-hat) cd firmware sudo python ./update.py I do not have exact errors, but it it went through blocks 1 to 108 and then would say update failed and then try to update again. So now it gives the error I posted first. ---

Wow…is that it? I followed directions from another blog post and now I am out of luck? So is it now just a waste of my money and a paperweight? ---

Can someone give me options? Or should I just consider the Skywriter and Pimoroni a waste of time as well as money? ---

I suspect that @gadgetoid may be able to help here. If we can’t get the problem solved, then of course you’d be welcome to return the HAT to us for replacement. ---

Before chalking it up as a fail, try: ```auto sudo python3 ./update.py ``` Sorry it took so long to get a reply. It’s always worth pinging support, or sending a DM on the forums if your reply goes unanswered. The forums are tricky to keep on top of. ---

I will try that and see what happens. Thank you. ---

I finally was able to get to try this and it fails and loops. Every line item gives a BLOCK OK. At end of each sequence of successful BLOCK update the result is as follows.: Finishing update… Finishing update failed!

How are you connecting the Skywriter, and onto what type of Pis? Additional question: what type of power supply are you using? ---

Pins are soldered to pi as delineated on the pin out diagram…resoldered(or heated to re-melt) to ensure good connection. Then the pins on ends of these short jumper wires are pushed into the correct sockets on the hat. Pi zero w is used Power supply is a USB supply made specifically for the pi. Keep in mind, the hat worked perfectly. Then after a command line shutdown of the pi…and a reboot the next day, the issue illustrated at first post above began to happen. ---

There must be a connection issue. Can you please post a picture? Also, how many ground lines have you used? Try to link additionals.
