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
- enable USB Debugging on your device
adb install keyboard.apkto install the keyboard app
I´ve done it without adb or anything else. Just download this apk: http://www.apkmirror.com/apk/google-inc/google-keyboard/google-keyboard-4-0-21173-1568296-android-apk-download/
Then pass the apk to a second phone. After that pass by bluetooth the apk from the second phone to the first. After that the installation option will apear and your problem will be resolved.
Following this advice I enabled USB Debugging (on my Moto g 2nd gen) and then I happened (on a whim) to look at Accounts before proceeding. At the bottom of the screen it said I could add an account so I went to do this - and there, suddenly was a keyboard again! So I was able to sign back into my Google account and get things working. I don't know if I have hit upon some safety feature, or what, but more importantly - it worked!
