computer doesn't recognize pinephone for OS flashing

[Xzska-collab]

1. never pull battery while phone is on
2. if you see jumpdrive on screen, you are basically booting from sd card
3. find correct path to pinephone via "sudo fdisk -l" on linux computer while phone is connected
4. just use "dd" via command line to write image to drive, more on https://wiki.mobian-project.org/doku.php?id=install
5. the clicking comes from the camera, i get that too while booting

Thank you for your reply. I perform step 3 in the computer terminal  and it displayed: 

Disk /dev/sda: 59.6 GiB, 64023257088 bytes, 125045424 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x7c9a118e

Device    Boot Start      End  Sectors  Size Id Type
/dev/sda1  *    2048 125044735 125042688 59.6G 83 Linux

Is the pinephone /dev/sda1/ ? or is the computer disk?

it's not the pinephone.. maybe try to write the installer to the card

1. download "mobian-installer-pinephone-phosh-alpha5.img.gz" from https://images.mobian-project.org/pinephone/installer/
2. extract image from archive, write image to sd card and put it into the phone
3. boot and follow the steps on screen

 In the terminal I am not able to extract the installer img. so I used my Mac 2011 to burn the sd card with Etcher, both the jumpdrive and the OS. I first tried with Mobian, to see if the pinephone would boot from the sd card, but nothing happened..black screen and blinking green light. Then I tried with Arch, same thing... black screen and red flashing light. On the first boot when I received the phone I used a 2GB sd, which still have the jumpdrive on it and flashing the OS worked so well. Now, I am using a 256GB sd....I don't know why is booting the jumpdrive from the 2GB sd and not the OS from the 256GB, but I'll try to get a sd with less storage and try again, as well as, research more info on how to extract the image on my bodhi linux terminal. I thank you for your help
