[Q] Locked out of Nexus S - Nexus S Q&A, Help & Troubleshooting

A few months ago while I was visiting family my cousin decided to lock me out of my phone by putting in the wrong pattern 30 times. I was then asked to provide my Gmail account and password to unlock it. However, when I input my Gmail account and password it says "Invalid username or password". I wasn't able to do much searching there since their internet was very unstable and rarely worked, so now that I'm back I checked and the Gmail account and password that I entered are correct, it just happens to not work on my phone. My WiFi and data off too, so that could be the reason why it's not verifying it.
When I turn off my phone and turn it back on while pressing the volume up button it does say that it's on fastboot mode and that it's unlocked. Not sure if there's any other information that I can provide that will be helpful. I really want to access my phone again without having to factory reset it since I've a lot of pictures that I haven't saved and I don't want to lose all my contacts again (not sure when I last backed up my phone or if I have ever backed it up).

Try this.

Thank you for the link. I tried both methods posted on there but it didn't work. when I typed adb shell it would say device not found. I believe my USB debugging is turned off.

If you have a custom recovery then you can try the same commands.
If you have an unlocked bootloader, then flash a custom recovery and give it a go.

I went into bootloader mode and selected recovery.. but that didn't do much. it just showed an android with a red triangle and an exclamation mark inside of it. Then it went back to asking for a gmail account and password.
I'm trying to flash a custom recovery but its still not working. I was using this site for guidance http://forum.xda-developers.com/nexus-s/general/nexus-s-guide-unlock-bootloader-root-t2034264 but in the "early necessary requirements" it says that USB debugging should be enabled.. which it isn't for me.
I tried using all 3 commands but all I get is "waiting for device" and nothing happens after that.

Can't even log in (stuck after lockscreen)

Hello
A friend of mine gave me his Xoom (MZ601) to rescue the data. But the problem is, that the device has pattern lock with state of too many wrong tries. I also received the credentials that was used on this device. I tried typing this credentials and i can't even log in. After typing email and password, clicking log in, it clears the password field and nothing happens.
Is there any way of rescuing the data on this Xoom?
I've thought about rooting it, but it needs USB debbuging enabled. Or at least make backup of data somehow (he said he has photos on it and few docs).
It seems to have 4.0.* android and looks oem locked.
Please help
//now im trying to oem unlock it and install cwm

nevermind, everything is lost
lol oem unlock will do factory reset

[Completed] Recovery mode is gone, Factory mode is gone, help me XDA you're my only hope...

So here is a string of steps I've already been through in trying to save my bricked Nexus 6: [Can't post outside link yet...]
Basically I got the 'your phone is corrupt' message from google and it kept forcibly shutting down. It would not boot up so someone suggested I side load a rescue OTA. At this point recovery existed and I went through all the steps and had it installing, only to fail mid-way through (~52%) and give me a 'read error' on my command prompt. I started the whole process over again just fine and it got to 73% before 'read error' failing again. I thought no big deal, I'll just keep doing this until it gets to 100%. Nope, recovery is gone. I cannot get there anymore. I start into Fastboot mode and scroll to recovery and hit power and it just goes to a new Fastboot screen and keeps flashing every time I try to select it. The Bootloader logs give me a 'failed to validate boot image: ret=-1' message and says 'Boot up failed.'
I can't find a single guide online that doesn't require recovery mode to work. At this point I don't care about my data and just want to get this phone working again before I throw in the towel and pay Motorola $175 for a refurb. I'm just barely over a year too. The Nexus 'expert' gave up and blamed the memory and maybe he is right but I wanted to run this by you guys first. This phone was completely stock and unrooted.
The only reason why I feel there is still a chance is because when I connect USB my computer reads it as an Android Device in Device Manager with 'Android Bootloader Interface' as a sub device. If the computer can read it, isn't there a chance that some kind of software exists that can forcibly load a new bootloader onto this phone without recovery? I'm 'competent' with computers and android phones but I haven't rooted or done any custom stuff in years so I'm at a loss for what's out there.
Thanks in advance for any help you can give me, even if it's to tell me I'm SOL.
Ok so far I have tried to load a custom recovery but that requires an unlocked bootloader. Then I tried using a toolkit to flash stock as a soft-bricked device but that also requires an unlocked bootloader and I can't unlock the damn bootloader. You know, I thought I was just playing it safe by leaving this phone as-is instead of playing around with it but it looks like I screwed myself by doing so.

Locked out of phone, no recovery, usb debugging disabled, not sure of next steps.

Long story short - I thought I had lost my phone so I used Google's ADM to lock my Mi4c, it asked for a password and I entered 8 characters incl. numbers and letters, as I normally would. Anyways found my phone and now it's asking for a 4 digit pin, which I've never set up, I have no idea what the it could be. I've tried all the usuals.
So in the past I've used the tutorials on here to flash my device (thank you very much ), but it seems which ever way I updated it last time, it has relocked the bootloader. I was just re-granted permission (I was surprised to find that the permission expires) to use the miflash unlock tool, which completed successfully (as far as I'm aware). I thought this would allow me to access the recovery but it seems to be gone, no Mi recovery or TWRP! Nothing happens when I hold down the vol up and power button. No trouble accessing the fastboot though.
My questions is, before I go messing trying to fix this device:
Can I flash TWRP without USB debugging enabled? I can't access the settings due to the pin.
What is the best approach to solving this? I was hoping to use TWRP to delete the *.key files and hope that would unlock the device, but honestly I'm not precious about my content anymore I just want my phone back.

Can't you just use android device manager again?
If your phone still boots up to lockscreen and is connected to the internet (mobile or better Wi-Fi) you should be able to access it from your computer or another device...

Unfortunately not, I've tried changing the pin with ADM but it just tells me that a pin is already is place.
The phone is connected to the internet (both data and wifi), I just can't figure out how to get around it.

If you contact Google support? Maybe they can assist a little or Google some more about the 4 vs 8 digits pin - there's something wrong, sure that the 8 digits aren't your PUK?
Maybe use ADM again, there're more options,
If you reset it via AMD?

Unfortunately every time I tried to replace the lock pin, Google told me that there was already a pin assign and it wouldn't be replaced.
Anyways, I'm back into my phone! Ended up having to flash the Chinese official rom using fastboot and the MiFlash tool. From there I could enable USB debugging, and flash TWRP and then install a custom global rom. Lost all my content, but a lesson learnt. No complaints, I'm back to being connected to the world!
Thanks for taking the time to help, I really appreciate it

After factory reset Google Backup asks for pattern, can't restore

My Redmi Note 8 suddenly stopped accepting my correct pattern lock, so I was forced to reset. It turns out I had Google Backup enabled, which was a happy surprise. However, it asks me for the previous pattern lock of the phone, which it still won't accept. This is incredibly frustrating.
Is there anything I can do to get access to the backup file or be able to use it? Will it get deleted if I don't restore it right now, in the initial setup?
Thank you.

Is this a second hand device? It seems that it is linked to another account.
If your device is unlocked, you are rooted and enabled previously USB debugging, you should pull your backup or some other partition.
The initial setup itself can't delete any data.
Interesting. If you did a factory reset with no internet connection would this thrwart it?
Be careful...
Never use bios, screen locks etc because this is what can happen. Ive gotten locked out of a bios before because of data corruption... with disastrous results. Had no lock been enabled nothing would have happen.
Data encryption for data hdds is an even worse idea... don't do it.

No, I had this phone for almost two years now and bought it new. Three weeks ago I tried to fingerprint unlock it with wet fingers and after several unsuccesful attempts it asked me for the pattern lock, which it didn't accept, even though I know the correct one. I've been trying to find a way to unlock it or make a backup ever since but found no solution, so I decided to reset.
After factory reset from recovery mode, it asked me if I wanted to restore a backup, and although I thought I probably didn't have one, I logged into the google account I used on the phone before the reset. Turns out I did have backup turned on! However, when I went to restore it, it asked me for the lock pattern at the time of the backup creation. Predictably enough, it didn't accept it, which is where I'm stuck now.

After factory reset, my device is indeed now unlocked. It is not rooted. I had USB Debugging enabled, but my laptop wasn't authorized, which is why in the end I couldn't unlock it or make a backup previously. I tried plugging it into the laptop in it's current state (waiting for the lock pattern to restore my backup) and tried adb, but it can't find my device at all. Previously, it just said unauthorized, so I suppose USB Debugging is now off.

Plugging it into the computer allowed me to use mtp mode and I took a quick look into the files. All of my files are gone, so I'm pretty sure everything got deleted before the setup stage.

Sorry, I'm not sure what you mean. Thwart what? I factory reset from recovery mode so I don't think internet connection had any role there, but I did have it on before. And I connected to the wifi before it asked me to log into google.

Where's the lock screen code being stored after the factory reset?
In the phone or cloud?
If in the userdata partition it should be wiped.

From what I understand, it was used to encrypt the Google backup file, so it will ask for it even if you try to restore it on another device. So I suppose the answer is cloud.

If you did factory reset device, then all is gone.
Regarding the status locked or not I referred to the bootloader, in case it is locked and the USB debugging is not already enabled then you have less chances to recover the device.
You should try flashing the device through EDL mode but old days (in my last RN8) it requires an authorized Mi account.

If you can factory reset it now FPR isn't active.
So when it first boots up after the reset if you can shield it from internet access you can disable Google backup Transport and Framework.
I think these are the backup pathways but you'll need to verify this.
If you need that backup data though it a catch 22. Perhaps if you keep the phone powered on until the backup is done and fully disable screen lock before rebooting... you can have your data without the lockout.
I may be mistaken. This is interesting but I'm very glad it's not my experiment!

Alcatel U5, flash, recovery, no command

Hi!
I have an Alcatel U5 (4047D) phone.
I want to sell it, so I've tried a factory reset without success. When try to go recovery mode, it says No command. After a while it reboots normal mode.
So I've decided, I flash a stock rom. In SP Flashtools, when I click on download, connect the phone, I see, the phone has connected in terminal, but if I am push the up or down volume, it takes me to the menu, where I can't do anything because of this no command. If I do not push up or down volume, the logo appears and sp flash says, error, try another usb cable, communication port, etc...
I thought I install twrp recovery, but I cant because bootloader is locked. Can not unlock with fasboot flashing unlock. It says: FAILED (remote: unknown command).
I can not enter the settings, because when I turn in normal mode, it says, log in with a google account what has already synced before. I gave it to my friend 4 years ago, he (of course) wont give me his email and pass, this is why I want to reset.
Can somebody tell me, how can I solve this problem?
