2. Error: The connection to ADB are down, and a severe error have occured. Who can solve this problem? Resolve: cmd jumps to the SDK tools file path under ADB kill-server and then adb start-server
3. Error: The connection to ADB are down, and a severe error have occured. [2010-03-11 09:36:56-helloopone] You must restart ADB and Eclipse. [2010-03-11 09:36:56-helloopone] Please ensure this adb is correctly located at ' D:\OPhoneSDK_1.5 \platform-tools\adb.exe ' and can be executed. Workaround: Method 1.cmd in adb kill-server, then Adb-startserver Method 2. Method 1 doesn't work, kill Adb.exe in Task Manager, and then restart Eclipse. Method 3. Methods 1 and 2 do not work, then look at the last sentence of the error: Platform-tools Adb.exe (my error is that there is no Platform-tools folder under the relevant path, so I chose to create a new folder, and copy all the files in Tools to Platform-tools) 4. The previous method tried or not, it is recommended to re-install a system, it is better to change a system. Some Daniel also said: Ms has some minor problems [size=large][/size]
