What about those 5 points: Xperia ZL testpoint.jpg ? Did you tried that trick with battery?

Tried those five points, also the battery trick - no dice  Phone still shows up (with the battery disconnected) as ZEUS flash drive on device manager. So that's what I had at the beginning. Is there any way to change the type to 'qhusb_dload device'?

By the way, are you aware of any s1 tool issue with 64 bit versions of windows 7? That's the only thing I haven't tried to change yet. Thanks, mate!

Tried all USB ports - no luck. Took out those metal shields and I don't see anything similar to those test points on Z!! Could it be  under the sim card metal shield? That one doesn't look like removable! Or is it located on the other side of the board (second picture). That doesn't sound right! Attached few pictures

Hi Jurij,

I followed all your instructions, but at step 8, I got this error message on my ZL (c6502) -> "can't get S1 command header  Loader not responding" (screenshot attached). Do I have any hope left ?

Few things:

  1. I'm using win 7 64 bit

  2. My device connects as a ZEUS flash drive to PC (not as 'qhusb_dload device'). So I tried both ways - with or without test point method, still got the same error.

  3. I see only one possible candidate for test point on ZL (circled in the second picture)

  4. My phone is 100% stock - not rooted, bootlocker's not unlocked.

Thanks a lot for your help! Keep up the good work. 

Great info, Thanks a lot! My phone is Xperia ZL (c6502). Do you think I can flash c6602 .sin_file_set onto my ZL? If not, can anyone please provide .SIN_FILE_SET for ZL (c6502)? Thanks!
