Hello,

I am almost 1 week now with my Jolla1 dead. No recovery mode / no power on etc. Today I connected it to USB without battery, and after some mins I noticed that in lsusb I see:

Bus 001 Device 071: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

Also, at dmesg, I saw:

[268233.413037] usb 1-1: new high-speed USB device number 71 using ehci-pci
[268233.527874] usb 1-1: New USB device found, idVendor=05c6, idProduct=9008

[268576.107322] cdc_ether 1-5.1:2.0 eth0: kevent 11 may have been dropped

Is there any way to bring the phone back to life?

Seems you have broken the partitioning on your mmcblk0 so the qualcomm preboot loader cannot find a valid boot or rescue partition. The device will enter a special diagnostics/load mode in which it can only communicate with special QC software not available to general public.

For some discussion on opening the protocol, see here for example; https://forum.xda-developers.com/showthread.php?t=2086142

Sadly noone have the needed files (Qualcomm tools can be found, but its not legal) . Without proper files, not much to do, only Jolla can restore the partitions. A little bit of investigation started on TMO - but no success.

Truly thank you guys for your comments, helpful to know that I have no realistic hopes for the device, looking forward for Xperia

At least with Xperia, if in the same state (won't boot any partition on flash, even Recovery partition), there are tools, provided both by Sony (pure Windows), and the community opensource Flashtool (multiplatform) that can talk to the Qualcomm bootload in flashmode.
