&lt;p&gt;I am happy to hear that it seems to be working now!&lt;/p&gt;
&lt;p&gt;If you experience new difficulties with getting the boards to work, there is a list of checks for common problems in the thread&amp;nbsp;&lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/24592/my-nrf52-nrf51-dk-kit-doesn-t-work"&gt;My nRF52/nRF51 DK kit doesn&amp;#39;t work&lt;/a&gt;. If none of that works it is probably a deeper fault, comparable to what you got after system recovery.&lt;/p&gt;
&lt;p&gt;Regards,&lt;br /&gt;Terje&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: DK boards (nrf52832DK and nrf52840DK) fail to load JLINK driver</title><link>https://devzone.nordicsemi.com/thread/209027?ContentTypeID=1</link><pubDate>Tue, 10 Sep 2019 18:38:15 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:4a52419b-1cc2-45bd-9b7c-1dfe36ba7180</guid><dc:creator>Keith Brafford</dc:creator><description>&lt;p&gt;When I used the J-Link configurator on a working machine I verified that my boards have the latest firmware (jan 7 2019).&lt;/p&gt;
&lt;p&gt;I was finally able to get it to work, but I am not sure which of these steps was the solution:&lt;br /&gt;&lt;br /&gt;&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;I &lt;strong&gt;did another system restore&lt;/strong&gt; to a previous date about a week earlier than the one I did before&lt;/li&gt;
&lt;li&gt;Plugged in one of the nRF52 boards.&amp;nbsp; Failed driver.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Copied the inf&lt;/strong&gt; file into the Windows\inf folder (a potential solution from a thread on segger:&amp;nbsp;
&lt;p&gt;&lt;a href="https://forum.segger.com/index.php/Thread/3918-SOLVED-J-Link-driver-issue/"&gt;https://forum.segger.com/index.php/Thread/3918-SOLVED-J-Link-driver-issue/&lt;/a&gt;&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;Re-enumerated.&amp;nbsp; Failure.&lt;/li&gt;
&lt;li&gt;Right-clicked on the failed load in the device manager and tried to &lt;strong&gt;update the driver&lt;/strong&gt;.&amp;nbsp; I pointed it to the JLink 6.34b\USBDriver folder and &lt;em&gt;it seemed to recognize that it is a valid driver&lt;/em&gt; (which is new&amp;mdash;before this system restore, pointing it at 6.44e didn&amp;rsquo;t work, but this earlier system restore left me with more JLink drivers to choose from, so I picked the next older one that I had before 6.44: 6.34b). &amp;nbsp;&lt;em&gt;But updating it didn&amp;rsquo;t cause it to load correctly&lt;/em&gt;&lt;/li&gt;
&lt;li&gt;Right-clicked on the failed load in the device manager and &lt;strong&gt;Uninstalled the driver&lt;/strong&gt; (while keeping the device plugged in and turned on).&amp;nbsp; I also told Windows to &amp;ldquo;remove the files&amp;rdquo; after it uninstalled. It uninstalled, then &lt;strong&gt;immediately self-installed the 6.34 version of the driver&lt;/strong&gt;&lt;/li&gt;
&lt;li&gt;It worked for a few minutes&amp;hellip;I was able to enumerate and see all the components of the driver for all of the boards, and I was able to use Nordic&amp;rsquo;s command line tools to connect through the segger-ob processor to halt, run, and reset the board&lt;/li&gt;
&lt;li&gt;Then the driver hung the machine on an enumeration, again&amp;hellip;kinda like what seemed to happen the first time.&lt;/li&gt;
&lt;li&gt;I waited a long time, and had to power off the machine&lt;/li&gt;
&lt;li&gt;Had to wait over night to let the RAID boot drive do its sanity check&lt;/li&gt;
&lt;li&gt;This morning, so far, the driver still loads.&amp;nbsp; I have two nRF52840 boards and one nRF52832 board attached at the same time, and the command line tools seem to be working.&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;I&amp;#39;ll let you know if this situation seems stable, or if the problem returns.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: DK boards (nrf52832DK and nrf52840DK) fail to load JLINK driver</title><link>https://devzone.nordicsemi.com/thread/209015?ContentTypeID=1</link><pubDate>Tue, 10 Sep 2019 16:00:13 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:825da563-4449-4194-a754-8812bfe75498</guid><dc:creator>tesc</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;As some boards work and others do not, this is extremely unlikely to have anything to do with the particular J-Link. Also the fact that boards work on other computers, just not this one computer where something seems to be wrong with the drivers...&lt;/p&gt;
&lt;p&gt;Can you check in &amp;quot;J-Link Configurator&amp;quot; what Emulator Firmware is found on both the working and non-working boards? (On a different computer, that is.) Should be a date and time, e.g. &amp;quot;2019 Jan 7 14:07&amp;quot;.&lt;/p&gt;
&lt;p&gt;I have found that when installing a newer version of the J-Link drivers, Windows 7 needs to install drivers again when I connect boards that are previously used with the same computer. Did you get any indication of such activity, and/or any message such driver installation failed?&lt;/p&gt;

&lt;p&gt;On the non-working boards, can you try, from Device Manager, to right click to get right-click menu, then &amp;quot;Update Driver Software...&amp;quot;? (Or, in the case of no driver, probably something like &amp;quot;Install Driver&amp;quot; or similar.)&lt;/p&gt;
&lt;p&gt;Regarding the nature of the issue, what happens when the board is connected to the computer and you try the command &amp;quot;nrfjprog --recover&amp;quot;? (I.e. what is the error message printed by nrfjprog, and is there anything else happening? &amp;quot;ERROR: There is no debugger connected to the PC&amp;quot;?)&lt;/p&gt;
&lt;p&gt;What is the output from &amp;quot;nrfjprog --version&amp;quot;?&lt;/p&gt;

&lt;p&gt;This is the same on the windows 10 machine as well&lt;br /&gt;&lt;br /&gt;When I plug in a non-working &amp;#39;32 board, I get only a COM16 (badged as no driver) in &amp;quot;Other devices&amp;quot; whose Hardware Ids show as:&lt;/p&gt;

&lt;p&gt;And there are no conflicts with regards to what machine (host or VM) takes ownership of the USB port and boards?&lt;/p&gt;
&lt;p&gt;Regarding removing JLINK versions, removing them through the &amp;quot;Programs and Features&amp;quot; method has always worked fine on my Win7 system...&lt;/p&gt;
&lt;p&gt;I have sometimes experienced that I must give Windows time to &amp;quot;install drivers&amp;quot; when I plug a DK into a USB port which it has not been connected to before, but after that everything has been fine. (In some occasions it has taken several minutes, though.)&lt;/p&gt;
&lt;p&gt;Is there anything left in the registry, after uninstalling J-Link and Nordic Semi software? (E.g a SEGGER folder under HKEY_USERS -&amp;gt; random folder name -&amp;gt; Software in the registry.)&lt;/p&gt;
