Please can anyone help k750 db2010 cid49 flashing led on startup all usual symptoms of needing eprom upgrade but am unable to connect to dcu60 cable only usb service cable and then I get this:

Have tried it seems all alternative routes open setool cracked (dont tel lasyk)

I know the otp is intact because I can get the imei even cid version with setool but will not load empty bootloader. Any help much appreciated.

If it's CID49 you can try with testpoint. If that doesn't work your flash chip is dead.

Yo can revive it with GOT tool or something else (UFS, Semc, SEMCtool8.4...but with setool2 lite edition v 1.08 dont try. For GOT you dont need TP like for many other tools.
What other tools for SE you have? Maybe some box?

I have tms server cable. Some davinci credits, some kk credits. Did have access to multibox but that has gone back for repair (worst thing I have ever bought). The test point route seems the most obvious choice but there is so little reliable information on how to do this. I read at least three different ways it should be done on different forums. earthing out components sounds a little bit risky unless you got a reliable source dont you think?

The way I did it: connect the negative of your battery to the testpoint.
It's not an easy job, you've got to disassemble the phone and the testpoint is very small.

You can use SE Tool cracked for the job.
