How to Unlock LAUNCH EasyDiag Locked Adapters(With Video)

Hi friends, good news for owners of Locked adapters LAUNCH EasyDiag dug .

Note: its not my work. i coped from other
Here you go.

Thread: LAUNCH EasyDiag Unlocking Locked Adapters
around on the Internet, collected information and … it turned out!
I will describe the recovery steps for both Locked and Blown
LAUNCH EasyDiag adapters .
We need a
dump of a non-blocked adapter (with 52 firmware on board). The programer
itself
runs the programmer in the J-link
and the program in which I did everything

Programs recommended by Adminom
program for firmware adapter

native application ST-Link

Before we begin, we will
use the utility from Segger to turn our St-Link V2 (clone) into the J-Link programmer
and install the program (downloaded from the link above) with which we will flash our Device * We disassemble the adapter (I took it apart on the board with a knife by cutting the place of the gluing of the case)

connect the programmer to the pictures

J-Link (ST-Link V2 Clone)

launch the J-Flash application
or ST-Link ( also works with St-Link V2, connect it to USB to get power.)

 

Create a new project select the controller STM32F207 IG

 

after all the procedures connect our adapter to the computer and connect it to the program in the Target tab, select Connect

and well on the video)) ))))

Good luck, the guys write, I will definitely prompt))))

Launch DiagunR71 resistor PCB rework

Topic: Damaged main board R71chip of Launch Diagun. (Professional advice needed.)

I bought used Launch Diagun and one of them has damaged the main board. On/off switch needs soldering and below that switch there is a tiny chip called R71, which broke off for previous user.

Does it contain any specific information/data for diagun or is it generic and interchangeable chip which i could take from a different kind of chipboards? I mean, as long as the name of the chip is the same R71, can I take that R71 chip from not diagun board and use it in diagun?

If not, can it be programmed and then used in diagun?

Sorry, I have no clue about chips and looking for professional advice. Thank you in advance.

Reply:

R71 is a 100 kOhm SMD resistor, can desolder it from any electronics, it is usually marked “104”.

If Launch Diagun freezes, common problem with firmware, flash needs to be reprogrammed.

Here you go…THE LATEST AND MOST CLEAR PICTURES:
Damaged PCB diagun
    

Freezing Diagun no1
 

Freezing Diagun no2

 
Here is chip code and I was told by ‘Gazownik’ on this site that R71 is 100kOhm resistor.

Hope that this helps. Thanks.
