&lt;p&gt;Are you asking whether it&amp;#39;s possible to re-upload the J-Link firmware onto your debugger chip?&lt;/p&gt;
&lt;p&gt;If your&amp;nbsp;interface MCU is the SEGGER chip (this should be your case, since you mentioned you have the v2.0.1 DK, but please re-check), then it should be possible to re-flash the J-Link fw using the programmer app, by putting the DK in Bootloader mode. You should be able to find the appropriate firmware from the following location:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/6431.pastedimage1732693000758v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;But if the interface MCU is the 5340 SoC, then I&amp;#39;m afraid it&amp;#39;s not possible to re-flash the J-Link fw onto it.&lt;/p&gt;
&lt;p&gt;Regards,&lt;/p&gt;

&lt;p&gt;The four LEDs flash, but Windows does not recognize it us a mass storage device and also Programmer cannot see it either without the 5340DK acting as the debugger probe.&amp;nbsp; Also, the nRF Connect Desktop -&amp;gt; Quick Start does not recognize it either as a 52840DK development board.&amp;nbsp; Is there a bootloader hex or some other firmware to restore the factory nRF52840DK firmware on the board?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Is there one in the&amp;nbsp;&lt;span&gt;nRF5_SDK_17.1.0_ddde560&amp;nbsp;&lt;/span&gt;example folder?&amp;nbsp;&lt;/p&gt;

&lt;p&gt;I am using the P20 method:&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/94001/programming-custom-nrf5340-board-using-nrf5340-development-kit?ReplySortBy=CreatedDate&amp;amp;ReplySortOrder=Ascending"&gt;devzone.nordicsemi.com/.../programming-custom-nrf5340-board-using-nrf5340-development-kit&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;But nRF Connect Desktop -&amp;gt; Programmer can see the 5340 DK board, and if I remove the VTG cable then it maps out the memory of the 5340DK. But when I re-connect (as it should be) the VTG cable, it says &amp;quot;core protection status is unknown...etc&amp;nbsp; &amp;quot;Press erase all button to recover protected memory&amp;quot;&amp;nbsp; . But in&amp;nbsp;Programmer (nRF Connect Desktop)&amp;nbsp; if I try to &amp;quot;erase all&amp;quot;, I get this red error message:&lt;/p&gt;

&lt;p&gt;Apologies for the delay.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;In order to flash the nRF52840SoC on the nRF52840-DK, you can use the 10-pin DebugIN port:&amp;nbsp;&lt;a href="https://docs.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/hw_debug_in_trace.html"&gt;https://docs.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/hw_debug_in_trace.html&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;And connect this to the debugger SoC on the 5340DK using it&amp;#39;s DebugOUT port:&amp;nbsp;&lt;a href="https://docs.nordicsemi.com/bundle/ug_nrf5340_dk/page/UG/dk/ext_programming_support_P19.html"&gt;https://docs.nordicsemi.com/bundle/ug_nrf5340_dk/page/UG/dk/ext_programming_support_P19.html&lt;/a&gt;&amp;nbsp;&lt;/p&gt;

&lt;p&gt;When I connect the J2 USB port (long side) of the PCA10056 DK to my Windows laptop and turn on POWER on the board, nothing happens. No LEDs, no sign of any device in Windows and in nRF Connect Desktop -&amp;gt; Programmer 4.2.2.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;If I disconnect the board, leave the POWER switch ON and hold down the IF BOOT/RESET button while reconnecting the J2 USB...then the LED5 starts flashing, and BOOTLOADER mass storage device shows up in Windows (with 108KB of 128KB free). It does not show up in nRF Connect Desktop -&amp;gt; Programmer.&amp;nbsp; &amp;nbsp;And after about 30 seconds the BOOTLOADER mass storage device disappears on its own, while LED5 remains flashing on the board.&lt;/p&gt;
&lt;p&gt;I have a &lt;strong&gt;nRF5340 DK&lt;/strong&gt;, PCA 10095, 2.0.0., 2022.4 and several nRF52840 PCA10059 dongles.&amp;nbsp; I also have the &lt;strong&gt;J-Link Edu Mini.&amp;nbsp;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;It&amp;#39;s a bit late here tonight, but if you could describe how to flash the PCA10056 with the PCA 10095 or with the J-Link Edu Mini, I will do that tomorrow.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;EDIT:&amp;nbsp;&lt;/strong&gt; when I connect the J-Link EDU Mini to SWD CLK/IO/GND/V-in pins on the PCA10056 DK and I open Programmer 4.2.2., J-link shows up as device, and the Programmer is trying to read the DK memory, but get this error message in red color:&lt;/p&gt;

&lt;p&gt;Could you tell me the revision on your DK? (white sticker on DK)&lt;/p&gt;
&lt;p&gt;When you connect the J2 USB and normally switch on the DK, is it being detected ?&lt;/p&gt;
&lt;p&gt;If you have any other DK could you please try flashing the problematic DK using that, or if you have any other debugger, could you try flashing your DK using that? This will help us isolate the issue to the Debug chip.&lt;/p&gt;
&lt;p&gt;Regards,&lt;/p&gt;
