Not booting , Black screen backlight is on

[rocket2nfinity]

Same here. Pinephone UBports Edition.
I had problems with booting from the SD from start "of out of the" box.
I succeeded once with Postmarket OS. Made no changes to EMMC. Only booting from SD.
After I tried to SD boot  with UBPorts an older version II can't boot at all.
No Jumpdrive , no factory image works from the SD.
Tried different SD cards. Power should be ok.
After the Pine Logo the screen is dark no read activity from the LED.

Woops....

Now what?

Sounds like partition tables got corrupted. Run gparted on your SD cards and then re-install ubports on one, or the jump drive image. Insert, boot into recovery and see if it succesfully can.  If so, then run gparted on your emmc because it also is likely corrupted. Mine were. I reflashed after gparted and all works now. Running  ubports on emmc and pureOS on sdcard

Erased the SD card completely (SanDisk Ultra 32GB), ran gparted on it and then used dd to flash yesterday's release of jump drive. Popped into the phone with battery fully charged, the display is still not showing anything and only the backlight is turning on. Have a 6MB video of the boot process but not sure I can attach it here, can message or PM if needed (edit: added to the Telegram chat)

Can you try with UBPorts build 54 from this June? Do not do the clock patch, just dd the image file to the SD card and try to boot to recovery

Ahumm, if there was a forum thread named: "Hall of Lame" I will be high listed.
But here is my confession.
I haven't used a SIM-card yet because I only want to discover first. And my old eyes didn't noticed I have put the SD-card in the SIM part.
My eMMC is corrupted that's for sure. But I have Mobian running from the SD.
Thanks for your help and sorry for your time....

A common mistake I keep seeing in both forums. But you're having fun, no? That's what matters...

UBPorts build 54 downloaded, extracted, and flashed to 32GB SD card (erased, formatted in gparted). Same behavior on boot and recovery where the display is only backlit and no images appear. The only difference now is there is a sound when plugging in the USB-C cable that was included in the box, does not make a sound in recovery mode. I've left it sitting for awhile in case anything needs to load, no change.

Sound? From your computer or the phone? There shouldn't be any sound from your phone unless it actually booted. If you're getting one and it's not booting then you may have a short somewhere in the case. It might be worth your time to open the case, remove the screws and check for loose or crimped connections/wires, excess solder traces, anything out of the ordinary.

It could also be booting and crashing due to the clock problem, but your should see some boot activity before then. The USB cable that came with the phone is charging only if I recall. Use another cable to read data from the phone
