You may need to reboot after altering this to get it to actually turn WiFi on. 

This solution comes from <a href="http://develnetwork.blogspot.com/2012/05/turn-on-wifi-from-adb.html">a blog post</a> that remarks it works for Android 4.0. I don't know if the earlier versions are the same.

Try out the following which did work for me.

Method 1:

<ol>
<li>Turn on the device</li>
<li>Plug in the USB cable </li>
<li>You will get the screen for turn on USB storage.</li>
<li>Pull down the notification drawer</li>
<li>Turn on wifi/Data</li>
</ol>

Tested on AT&amp;T Fusion working fine.

Method 2:

Use the method given by shkschneider

<pre><code>adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell input keyevent 20 &amp; adb shell input keyevent 23
</code></pre>

This works only if you have USB debugging turned on. If you do not have USB debugging turned on under Development do the following.

<ol>
<li>Turn off the device.</li>
<li>Boot into recovery mode (Power button + Volume up)</li>
<li>Plug the device into computer.</li>
<li>Use the ADB tool to execute the same commands given by shkschneider</li>
</ol>

Tested on AT&amp;T fusion working fine.

However, I'm pretty sure that Google actually stores your email and password (at the time of saving to the device) for times like these. So when it needs to be unlocked, it won't require an internet connection.

I could be wrong. Either way, when I had this issue, I had internet connectivity, and I knew my username and password and it didn't care, kept saying they were wrong (even though I was logging into my email). Had to format the phone at the time!

Good luck.

You should start the WiFi activity from <code>adb</code> then simulate inputs:

adb shell input keyevent 20 &amp;&amp; adb shell input keyevent 23

Here is the list of <code>adb</code> inputs: <a href="https://stackoverflow.com/questions/7789826/adb-shell-input-events">#7789826</a>

I'm not sure if those keyevents are the right one for your case, but I think it will do.

I was in the same situation on a Samsung Mini II. I got around it eventually by holding down the power button until the "power off" menu appeared. From this menu it was possible to enable the network data connection. 

Then signing in to my google account using @googlemail.com (rather than @gmail.com) seemed to do the trick. Though the change of address may just have given the phone time to warm up the 3g connection rather than making any real difference.

blocks|key|277870|text|不确定这个相当简单的解决方案是否已经发布在这里的某个地方。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|277871|问题是手机没有wifi连接，没有根连接，USB调试被禁用(见鬼，更糟糕的情况)。不能使用ADB，因为"Adb设备“检测不到禁用USB调试的设备。已尝试恢复模式(无法进入)。已尝试紧急模式(Adb仍未检测到设备)。当我几乎要放弃的时候，就像是离硬重置只有一英寸之遥的时候，奇怪的事情发生了。当我像往常一样将手机连接到USB时，USB进入屏幕出现了。没什么新鲜事。然后我注意到的是，在这个屏幕上，实际上可以降低下拉栏和宾果…我能够打开wifi。然后进入谷歌账号，手机就被解锁了。|277872|希望我帮了什么人。|277873|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Not sure if this rather simple solution is already posted here somewhere.

The problem is locked phone w/o wifi connection, not rooted and USB
debugging disable (hell, worse possible situation). ADB can not be used since
"Adb devices" do not detect device with USB debugging disabled.
Tried recovery mode (can not enter it). Tried emergency mode (Adb still don't
detect device).
When I almost gave up and was like an inch from hard reset something strange happens. When I connect a phone to USB as usual USB entry screen appeared. Nothing new. What I noticed then is that in this screen it is actually possible to lower a drop down bar and bingo....I was able to turn wifi ON.
And then just entered google account and phone was unlocked.

Hope I helped someone.

我的电话已锁定(模式尝试次数过多)。要解锁，我需要在我的gmail帐户上输入用户名和密码。这是我唯一能解锁的方法。我无法启动任何活动，甚至无法打开wifi连接。没有互联网连接，我无法登录以恢复我的电话。也许在adb中有什么命令可以打开我的wifi连接，这样我就可以使用我的手机了？
