the battery that i’ve been mostly using has 99% charge and was able to hold a charge for 4-8 hours normally before i started trying this. i keep restarting in regular mode and it keeps showing 99%. Battery 2( charged to 66% ) is brand new has never been used before today. I’ll try booting that up normal, charging it and then trying to reflash when it’s at 99% next.
also tried on devuan ceres(13.0?) on different machine, same result
There are 2 way to put the phone on: Burn Mode.
One way as you described it above.
Second way is keeping the vol+ pressed before connect the cable, but the cable need to be connected on host first, have u tried the way?
I have given up on that method of reflashing.
Instead I use a micro-SD card with a clean L5 image burned onto it.
If you want help with that I can share step-by-step instructions
Given that you apparently have a working bootable phone … how about just connecting the normally booted phone to your host computer via USB and confirming that your host computer sees the phone at all (using lsusb)?
If the host can’t see the phone when the phone is in normal mode, I have my doubts that it is going to work when the phone is in serial download mode. (In other words, don’t worry about the Vulcan death grip and don’t worry about uuu / the flash script until the phone at least shows up when booted normally.)
FWIW, as my computer doesn’t have a USB-C port, I have never used serial download mode via the Purism-supplied USB-C to USB-C cable. Instead I have always used a USB 3.0 USB-A socket on the host computer with an Irvine-supplied cable that is USB-A M to USB-C M, and that has always worked for me. This also has the advantage of reducing the number of orientations for the USB-C plug(s).
You realise that the µSD card goes in the SIM tray on the side? So you could never have used this as a mobile phone?? (OK, I admit that I have not used the Anti-Interdiction service, so I don’t know which things get covered in glitter polish.)
