[General Questions and Answers] droseofc:
Its going to be near impossible to login without a keyboard popup and sorry about the switchback thing, must be a zte setting. Youve reset the phone using recovery? Power off, hold vol up, home and power until it turns on and let go should get u to recovery. Factory reset, delete cache reboot. Should take you to initial setup until you get to google login part where you will need to log in with same account used the first time phone was setup. Is the phone asking for a pin or does it say this phone has been reset in an unusual way or whatever and to log in with owner google account? If its just the pin screen and u havent reset it id maybe hold off as it may be easier to get through that than the google frp lock. If you have a mini usb to usb otg adapter you could plug adapter in phone and use a pc keyboard, or if u have a rooted phone laying around you can use usb keyboard app which when plugged in is the same as a keyboard. Its not going to help with any amount of accounts made if you have no way of typing them in at that log in screen. If you have factory reset and it does get to google login screen asking for first owner login and no keyboard popup there had to be an issue and i would download/redownload stock firmware and flash in odin because if its asking for a login it should definitely have a way fof entering that in. The only time ive had no keyboard popup is when i have set the default input method to something other then samsung keyboard like sixaxis controller which needs switched back to use keyboard

If u havent reset the phone and it is a pin and if u had enabled usb debugging prior to the phone being locked you may have options. If usb debugging is not enabled or if u did reset it options become slimmer. I have heard that not trying to login on the device for 72 hour will reset the account thing and allow a login. Not sure if it works, never had the patience.

I found by trying whatever i could theres some way of getting to the settings itself. Easiest was by getting the google app to pull up and searching settings. I did this by getting to the app settings from talkback options and finding someway of getting to its app settings and then clicking menu and going to all apps. From there you could find keyboard and make sure its allowed access to each option. If google app doesnt list settings as a option you will have to make sure in app settings you enable access to phone/storage and then it should. I clicked basically every option available in every route there was and some was dead end, some would get into areas not available before. If your issue is keyboard id try to get to its settings by trying everyroute u can and enabling access for it and every application you think may be helpful in getting where you need. I found when its locked out nearly every app has no access to any features by default so for instance keyboard may not have access to phone and wont popup when needed. You will need to show system apps once in the app settings by clicking menu up top. You may also want to go to apps that can change system settings and enable ones that appear useable. If u get there u can also force stop setupwizard and clear data which will allow bar up top to be pulled down making getting there a whole lot easier. Dont get hopes up, i did all of this and in the end gave up. Without being able to install apps its kind of hard to bypass. May have been a simple enable of whatever installs apps to allowing access but didnt find. The last thing i did try which may have worked was getting another phone and turn on hotspot and on locked phone connecting to it at wifi screen and as soon as it goes to checking connection screen turning off the hotspot and phone should go to screen asking for first and last name. U could do this with wifi just easier to turn off on hotspot. It may take a few tries and probably will. 9/10 times itll say there was an error and go back to wifi setup. I was able to enter name and setup a lock for the screen. Didnt venture further. Also when i did get to settings and went to backup and reset clicking reset didnt do anything. This is the way to reset without getting frp locked out but the option was disabled.
