No keyboard after factory reset. Can't install keyboard on phone with bluetooth, google play, sd card, etc I have a Coolpad Quattro with Gingerbread 2.3. I didn't like the keyboards that came with the phone so I deleted them and got another one from the app store.
Because my phone was running slowly, I did a factory reset. This is the second time I did it.
Only this time, it didn't restore my keyboards. Now I have no keyboard to use, and I cannot sign into the play store on my phone, so I can't install a keyboard from Google Play. I have tried to send a file via bluetooth, but that doesn't seem to work either. I really need to use my keyboard, and I have reset the phone three times now. What can I do?
You just created a nice chicken-and-egg problem: to install a keyboard via the playstore, you need to configure your Google account on the device first. To do that, you need a keyboard. Note: never delete the (last) keyboard app from the system apps; a factory-reset removes all user apps, so if there is no keyboard app as system app...

Here's what you can do -- provided you've got some keyboard as .apk file:


enable USB Debugging on your device
use adb install keyboard.apk to install the keyboard app


If you don't have ADB installed on your computer, either install the Android SDK -- or see Is there a minimal installation of ADB? for an "ADB lite" variant.
