[Q] Change google account without hard reset on 2.3?

Hey guys, just wondering if it's possible to change my main google account without factory reset? I know it was possible on older versions of Android, from what I've read, but is it possible on GB?
Thanks

Try the following:
Go to Settings -->Accounts & sync
Press on the account you want to be deleted
Press "Remove account" on the next screen

Tried that, when I select the dummy account I registered with it won't let me delete unless I do a factory reset

It worked for me on CM7. I added a second Google account and then successfully deleted that newly added account.

I tried to do the same the stock non-rooted sense rom, and got the same reply. Had to do the factory reset. Maybe it will only work on rooted phones, or perhaps only some custom roms. I don't know.. Is yout phone rooted? Do u run a custom rom?

Yes my phone is rooted and is running CyanogenMod 7 (CM7), but I really doubt that this has to do anything with me being able to do what I've described, as this is a standard Android functionality provided by Google itself, and not a third party hack/addition.
BTW, are you trying to delete the only one currently existing account? Maybe if there is only a single account, then it cannot be removed... just a thought. I created an additional account just for the test and then deleted it, and did not mess with my true account.

The main account signed into on the phone is locked until you hard reset - no way to change it otherwise

Yeah, I'm on MIUI and I've added a second account but can't delete the first one. Which I don't care much about - but I can't change my Talk account to sign in with a different one, which is what annoys me..
Anyway, thanks for the help guys

[Q] Locked phone and I don't know the email !

Hello.
My brother locked my HTC Desire HD by entering the wrong pattern.
Now I have to sing in with my mail but I can't remember what mail was it.
Is there a way to check what mail is registered or just backup my contacts and than, I'll do a factory reset ?
NOTE: USB-Debugging is disabled and when I concect the phone to the PC it says Charge Only.
If' there's a way to root it with download mode or turn debuging mode on or backup contacts or find the registered E-Mail, please tell me because I have 1000+ contacts and they're not backed up on Google.
Thanks in advance.

If you synchronized ur contacts with google, then after a reset,your contacts would be sent right back to your device after signing in with that acount. If you dont remember that account then am afraid you are going to loose em.
I havent heard of a way to enable USB Debugging remotely. It can only be enabled from the device.

I can't remember what account I used. If I knew i could reset my password or install Lock Bypass from my PC on Play Store but I don't know it.
I can't afford to lose those contacts :/

Then your options are really limited. Unless....
This is going to be difficult as i havent tried it before but it might be possible.
What i would want you to do is flash a custom recovery and back up ur rom. Then send the file onto ur pc and extract the backup. And go through the data part, since your conacts are held by an apk called contacts storage.
I havent tried it before.
But it might work

I can't access my phone because it's not rooted and usb debuging is disabled so I can't put a custom recovery :/

Don't get Panic...
After reading all the conversation, what i was thinking is that, If you're not rooted then you must be on Android OS 2.3.5(last update) or lower. So you can do either login into all your Gmail accounts One by One and check which accounts has contacts sync with number which you were expecting not to loose. If you find that one then just click "Forget Password" on your device. They'll sent reset password to your account or else last option Hard Reset.

I tried all the mails I can remember but non of the works :/
It doesn't give me a "forgot password" option :/
None on the methods in that link worked...
I'll try to do something with Android SDK and terminal when I put the phone in Fastboot mode because it's the only way that my PC recognizes my phone...
I'll let you know what I've done

How does security and encryption defeat someone just booting into recovery?

Regardless of device encryption and fingerprint scanners and the like, couldn't someone just get your phone, boot into recovery, and factory reset it? Wouldn't that undo any security you had on device?

Yes but the actual files have been encrypted. So while they can start the device fresh and use file recovery tools to "get" the old files, they are useless.

And they would be useless to everyone after that, even you? I guess that would be pretty good. So you encrypt to protect your user data, and you fingerprint lock to make sure nobody can ever decrypt, even if they factory reset thru recovery, which will get past your fingerprint scanner but not previous encryption. That right?

Actually since lollipop you must log out of your Google account before a reset. If you just factory reset you well still have access to the device to track it out wipe your account from it.

I could be wrong here, but if you have stock recovery, a factory wipe can only be started in the phone's settings menu. If you have twrp installed, a wipe can be started with out being in the phone, but you need a password to start it.
If you do wipe the phone, it is still useless as you need the persons gmail username and password to complete the setup, so the phone is useless to all other users bar the user of the phone.

I think you can factory reset from stock recovery.
So I don't get it. I thought user data was encrypted from phone, i.e., the internal storage. If I factory reset, I don't need a Google account to start the phone up. So then couldn't I access the internal storage data with a file explorer?

You have to authorize the phone to sync with your computer so you can not get on that way either. If you do not authorize you can not push adb or anything else.

As km8j said, yes, you can factory reset the phone, but you won't be able to recover any of the encrypted data. That's why before you get rid of an old phone you should encrypt (if it wasn't) and wipe it.

Thats not quite right. If you factory reset your phone, you do need a google account to complete the initial setup wizard. The only exception is if the user releases it from his or her's google account so it can be sold on.
But yes to complete the instillation it will ask for a google account that has been authorised and wont continue until it gets it. This happens automaticly the first time you sign in to play store.
Also factory reset will fully wipe the phone, brand new out of the box. It also wipes the users data, so if you were able to get on the phone, there would be no data to access. I really do like the way google have thought about it. Also I never keep anything on the phone that I would consider critical.

A lot of inaccurate information here. You have been able to skip that Google account setup on all android phones for the past few years. Also in basically any file system, when joy delete a file, even formatting, the content is not deleted. So while the information is not there at face value when you wipe the phone it can easily be recovered without encryption.

Yeah, that keeps confusing me. I have activated so many phones without inputting a Google account. It says "skip" right there on the screen!

Didn't Google introduce the security features with the Nexus 6 and 5.0? It locks the phone to your google account even after a factory reset but requires compatible hardware.
I haven't seen it mentioned with this year's devices but when setting up a pin on the 5x I believe it asked if I wanted to enable that feature.

No. If your data is encrypted, no one can access it without your decryption key. As for access to the device, if you had set up a Google account on the device, and had a lockscreen password/pin/pattern/etc., then no one else can use the device other than you unless you remove your Google account and lockscreen password before you factory reset. This was a new feature introduced with devices that sold with 5.0+

With the stock recovery, you can reset either from within Android or from within the stock recovery.

Prior to devices shipped with 5.0+, this was true. No longer.

Yes, you can skip Google account setup. However, IF you do set up a Google account and a lockscreen password, THEN you cannot skip the Google account setup on that device after a factory reset (if you hadn't already removed the account prior to the reset).

Unable to bypass factory reset protection even with the correct Google account

Hi, I bought a Nexus 5X for a friend a few weeks ago and got it updated to Nougat. I used my own Google account to setup the phone and install some apps. Then, I removed the device from my Google account, factory reset it, and gave it to friend. When he switched it on, it asked to enter the original owner’s Google username and password, so I gave mine. But after logging in without any error message, the phone displays the same screen over and over. Asking to enter the original owner’s Google username and password. We tried to wipe user data in recovery mode also. But the same issue occurs. Anyone knows how to fix this? Please help.

Did you change the password on your google account.
If so, there will be 72hr lockout on that account for activations.
If you try to early, it resets the 72hr counter.

@minnix wait the 72 hrs as advised or check online for a current bypass method or flash the TOT with the LG Up tool as if your phone were bricked.

One other thing, the best thing to do to avoid factory reset protection is remove account from device as opposed to what you wrote (remove device from account)

Install an OEM Rom (to bypass google authentication)

Hello!
I have been using a z2 well for the past 3 years. I like it so much that I purchased about 2 years ago a used z2 as a back up. Well, now I am going to send my primary z2 for battery change, so I tried to set up my back up phone for service, but I am stuck on google authentication. I used to be able to log on to my google accounts without any problems, but after I changed to a treble rom, the phone asks for a google account of the previous owner, it seems.
Just installing a rom (AospExtended-v5.8-z2_plus-20180813-1655-OFFICIAL.zip) and not installing opengapps doesn't help because it still asks me for email account.
So, here is my question. Is there anyway for me to wipe the phone storage, system partition, install a factory rom, so that the phone doesn't ask for previous owner's account?
I downloaded tool-all-in-one and verified that my pc sees z2, but not sure how to proceed from here.
I would really appreciate your help on this.
Thank you!

1. U can qfil stock rom and unlock bootloader.
2. Don't select option of restore account while doing initial setup.. Always select start as fresh option ..
3. Wipe all from twrp.. Select wipe internal storage as well..
You can go for any one option.. Should work .
