Locked out of my Z4 - how do I get into recovery? - Xperia Z4 Tablet Q&A, Help & Troubleshooting

About 5 weeks ago, I changed my Google password, which is something I do once a year or so.
Today, my Z4 (WiFi version) has an "authenticate" screen popping up. It is asking me to sign into my google account. Once I do, I get a confirmation on my cell phone that I am attempting to sign in, is this you? I click yes on my cell phone to authorize my Z4. The problem is, the Z4 then goes back to the "authenticate" screen. I seem to be stuck in an authentification loop.
I would like to just do a factory reset on my Z4, but I am unable to get into recovery. Is there some trick to it on the Z4?

The answer is: Us another phone with Google Translate and translate the Chinese into English. You can then easily set the default language to English!

[Q] Too many pattern attempts - LOCKED

Hello everyone.
Today I left my phone (galaxy S2) in my cousin's hand, and he tried to unclock my screen lock pattern. After too many attempts, my phone got lcoked and it asked me to sign in using my google account. I did so, and the phone got unlocked.
But when I press the lock button, or the phone gets locked automatically and I press the lock button to unlock it, the "too many pattern attempts" screen comes back again. Also my sim card is not being detected even though its there.
I have tried rebooting the phone, disabling the screen lock patten in security settings, disabling google account. Nothing has helped so far!
When you disabled the screen lock setting, what happens? You could try booting into recovery and wiping cache. If that doesn't work, then you'll probably have to factory reset.
When I disable it, nothing happens, as in it shows that it is disabled on the security settings. But when I press the lock button, the too many attempts screens comes back again. I tried a fctory reset too. Its still there! This is so frustrating!
Flashing a new rom should do the trick.
No you don't have to Flash
Try this please:
It was all about this "Two-Step Verification" security of google!
I tried everything... and I mean EVERYTHING (except flashing my XooM), but at the edge of giving up, I signed into my google account and issued an "Application Specific Password" for Xoom from my Google account.
I used my [email protected] with that Application Specific Password and it worked. (do not enter spaces in the password)
There is one solution
Hello,
I had similar problem with my Motorola Xoom WiFi. My friends was playing with my tablet and they was trying to guess my login pattern. Unfortunately sign in via Google account did not worked and WiFi network was turned off. So I was looking for way how to unlock it without root access.
Finally I found it. I wrote an application which turns on WiFi. It is quite simple. There is one requirement, you have to have enabled debuge mode. After installing app via IDE (eg. Eclipse) WiFi is connected to known network and you can log in with your Google account. There is also possibility to set network parameters in app code before compilation.
I hope this helps someone with this problem. At the end I want apologize for my poor english
Regards...

Sometimes simple is best. If you saved the rom, go into recovery and restore the saved rom.

Just bricked my Tablet with MXTP...

Hi,
just bricked my Z4 tablet by only restarting it.
After the restart the Anti-Theft Protection kicked in and didn't accept my google password.
Google Account Authentication was correct, but the MXTP-Authentication keeps saying: username / password not correct...
Sony Support told me to send in the device to repair it at MY cost!
Nice, MXTP kills the tablet and I have to pay for it...

Try this method to see if it lets you log on?
Done this already, since that, the website doesn't recognize the tablet at all...
This behaviour seems to be caused by the fact, that, after the factory reset, the myexperia-app is not starting on boot so it can't connect to the website....
You can say, this method has deep-bricked the tablet... =(
Got it back from repair (Sony told me to send it to w-support.com).
40 € for a destructive flaw in Sony's own software.
They did some kind of obscure repair-flash, but how?
Thanks and NEVER activate this piece of crapware again...
At least they hadn't changed the motherboard unlike other stories from the M4 Aqua...

You can fix this by flashing lollipop with flash tool. I used the one from the https://forum.xda-developers.com/z4-tablet/general/guide-safe-bootloader-unlock-restore-t3362391
Wipe everything you can when flashing. After it's done flashing you will have about 30 sec on every boot before the lock screen hits.
On the first boot set the wifi settings from the lock screen. Then reboot and start setting up the tablet. Skip everything that can be skipped. You have to continue to reboot and do it over and over and over until you get the hang of it. Once finished setting up tablet. You will have about 30 sec to go into settings from menu on every boot. From here set up experia protection again, choose a gmail and pass thats quick to type because you will not have allot of time. When protection is activated you will have access to tablet again. Deactivate.
This works. I can confirm.

[Q] Stuck after Factory Reset - Email Authentication (Galaxy Core Prime)

Hello guys!
I work at a smartphone repair shop fixing phones both hardware and software issues. A customer came in yesterday, they just bought a Galaxy Core Prime from T-Mobile (SM-G360T). The same day she was partying, setup a password to unlock the screen and couldn't remember it the next day.
I told her I could remove the password however she would lose pics & docs since we had to do a factory reset.
A few hours later she came back in and showed me this weird loop the phone is going thru. It asks to setup a Wi-Fi and enter her gmail account. Upon entering the gmail account it goes back to same screen to accept terms, enter Wi-Fi, etc.
I concluded this is the copy of Apple's iCloud lock, obviously, albeit it seems filled with bugs. If that is the case then what is the website I can go to remove the lock - same thing as going into iCloud.com and removing "Find my iPhone" - that would remove the lock for android? Does google even allow removing of this feature online?
I have checked email/pass the information is legit, all the email notifications are there.
My other alternative is download a different ROM (since I can't find the T-Mobile one, seems it just came out - SM-G360T) and try restoring via ODIN, however, I'm not sure it will work since I've done a factory reset, thus removing USB Debugging.
Help me out if possible guys, thanks in advance!

If it was her Google password that was reset, you must wait 72 hours before factory resetting after changing the Google password. That's what this sounds like. Try entering the old password or wait 72 hours.

The password was never reset though, she had the same password before even purchasing the phone. Does that 72 hr thing still apply? I'm just confused as to why there's no place to deactivate this like in iCloud's "Find my iPhone". I can access the account, have searched all settings, I even get the notification email when I login from the phone itself, but it just goes back to terms, wi-fi, enter email, repeat. LOL
I'm guessing the T-Mobile variant is brand-new as well (SM-G360T) since I can find many other ROMs but none for the G360T.
Oh well I'll wait til the 72hr period or ROM shows up, thanks for the help :good:

Galaxy Core Prime Looping Hell
The phones keep looping back to the login screen beacuse of a security feature put in place by samsung. We must contact them directly and submit proof of ownership ( proof of activation or copy of receipt) in order for them to disable this security feature. The number to call is 800-726-7864.
you can remove that device from this account.

Google Assistant Won't Do Anything While Device is locked... (Galaxy Note 8)

Alright, so at first, google was working fine. while the phone was locked, screen off and it was in my pocket, I could say "Hey google, start a timer for 5 minutes" and it would confirm and start the timer.
Then I updated... and for a while it was saying "Sorry, I can't do that while the device is locked, go ahead and unlock the device". I followed about a dozen suggestions online and one of the suggestions (I'm still not sure which one) worked.
BUT: There's now this problem of: if the screen is off and I say "hey google, start a timer for 5 minutes": The screen will turn on and show the pattern unlock screen (as if it wants me to put in the pattern). If I leave it alone, the screen eventually turns off and google finally responds with "ok, starting the timer"... but then it never actually starts the timer until I pull the device out and unlock it.
Another strange thing is that it won't use the google assistant voice I selected (I selected a natural-sounding male voice but it still uses this robotic-sounding female voice).
I've been through countless forum posts, suggested fixes, have tried everything from restarting to the phone to clearing cache, uninstalling/reinstalling google assistant, changing security settings and even went as far as to factory reset the entire phone... nothing has worked so far. The problem I think is that all of those are solutions to problems that are SIMILAR to, but not exactly like, this. I'm wondering if anyone else has run into this specific problem and if you have: were you able to fix it? How?
It's just really annoying :/ This used to work so well. I used
PHP:
it for EVERYTHING. Now it doesn't really work at all unless I have my phone out and unlocked
Darn, it IS actually still telling me "actually, I can't do that while the device is locked. To keep going, go ahead and unlock the device". SO yeah... still just doesn't do anything at all if the device is locked. Only way I can get it to work is to uninstall all updates... but then it it reinstall those updates whenever I tell google play to update all. If I want to avoid that I guess I just have to go install updates individually/manually?... :/ This stinks. Just want my google assistant back to how it was working before (aka actually working - while the device is locked).
