Cannot communicate over adb/fastboot after flashing image

[Alex Kushleyev]

@Kashish-Garg-0 , I understand, thanks for clarifying.

My colleague, who has more experience with this, was out of office last week, coming back tomorrow. I will make sure he takes a look at your post, he may have some suggestions. @tom

@Kashish-Garg-0 With your device plugged in to your host pc via usb, what do you see with lsusb on your host PC?

@tom

Bus 005 Device 008: ID 05c6:900e Qualcomm, Inc.

Thanks for your help!

@Kashish-Garg-0 Okay so the device is booting into EDL mode, which is what is used for QDL flashing. Can you confirm that the EDL switch is turned off?

[Kashish Garg 0]

@tom Yes the EDL Switch is turned OFF, pointing away from the Processor

@Kashish-Garg-0 And when you went through the QDL process did the QDL flashing complete as expected? Should take around 10 minutes to complete

@tom I just re ran it and it took around 7 minutes or so and gave the appropriate output:

@Kashish-Garg-0 And then if you remove and replace both power and usb is it still booting to that same mode?

[Kashish Garg 0]

@tom You mean is it going to EDL mode after replacing power/usb and moving the EDL Switch to off?

Is what is being printed with lsusb now

[tom]

@Kashish-Garg-0 Sounds like we'll have get an RMA going for this one: https://www.modalai.com/pages/rma

@Kashish-Garg-0 It's possible your board has a QSM8250 (M0054-2) instead of a QRB5165 (M0054-1), see here for the diffs: https://docs.modalai.com/m0054-versions/#m0054-1-and-m0054-2

If that is the case then you will have to QDL using a different build, which you can download from downloads.modalai.com, look for M0054-2 Starling QDL Image 1.7.4 2024-02-09-1.7.4-M0054-2.zip under the "All" category
