Device detected but nothing happens
Opened this issue · 10 comments
I'm using a huawei Y7 Prime 2019 trying to unlock the bootloader on windows using edl but this happens
C:\a\edl>edl
Qualcomm Sahara / Firehose Client V3.62 (c) B.Kerler 2018-2024.
main - Trying with no loader given ...
main - Waiting for the device
main - Device detected :)
C:\a\edl>
nothin more happens(sorry for my bad english)
Why not give it a command like edl printgpt
Same issue here and this does not change anything.
This is with libusb.
If I try with serial port I get this:
Traceback (most recent call last):
File "C:\tmp\MC7010\edl-master\edl", line 393, in
base.run()
File "C:\tmp\MC7010\edl-master\edl", line 293, in run
version = conninfo.get("data").version
AttributeError: type object 'req' has no attribute 'version'
Solution is to install the WinUSB driver with Zadig.

I have had absolutely the same issue.
I have tried to install "WinUSB (v6.1.7600.16385)".
For whatever reason, it would not work directly (would be empty), but only after a restart of Android device in EDL mode (without disconnecting the cable from the PC).
OS is Windows 10, USB port is 3.0.
My computer: Linux pop-os 6.9.3-76060903-generic .... x86_64 x86_64 x86_64 GNU/Linux
Smartphone: LG G6 H870 with latest (last) Android 9
EDL mode with shortcut on motherboard
lsusb: Bus 003 Device 017: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)
I got the same behaviour as mentioned above:
"main - Device detected"
In Visual Studio code I followed the debugging till ...
edl/edlclient/Library/Connection/usblib.py:391 as in line 395 it throws the "usb.core.USBError" exception with message "Operation timed out".
I changed the timeout to 1000 msec with the same result
As I think this happens before any firehose loader is used ?!
How to continue ?!
Maybe the reason was low charge of the device ?! I charged it up to 100%
Now I get:

Well, on my Xiaomi, we need battery disconnected for EDL mode.
On Linux it can reply with printgpt results, but it does disconnect and various errors (some might be loader related).
Tried many solutions on Win 10 on two (AMD) PC but never get results, program just end after detection.
Seem to be a Win10/libusb issue maybe testing more versions can solve it. But I'm so tired of this.....
Sounds cumbersome and annoying :-(
I had some problems under Linux with edl; device busy, or "restart phone" advice due to some errors ...
As I realized that a possible reason for my problems was too less charge on my mobile, I changed to Windows (11)
and established a stable connection via QPST/QFIL.
But I explicitly use a firehose (obviously the right one) that I found after some research

Mmm, it's fine to do stuff like disconnecting the battery when testing for the correct Firehose.
It makes rebooting easy and doing nothing you're only drawing ~100 mA or so.
But for reliability or flashing there are going to be some peak currents that want a battery.

Yep.
Hey thanks Renate, I found your advice to always keep the cable connected, shorting test points and long-press power while keep on testing loaders worked for me.
Can now read and write to partitions.
I also fed power to USB from another source, for stability, just in case.
