After following a process elsewhere on XDA to set up a pin lock, (here: http://forum.xda-developers.com/showthread.php?t=1848962&highlight=lock) I've been locked out of my device, with the response Too Many Pattern Attempts.
It says: "to unlock, sign in with your Google account." But I do that, and receive an invalid login response. (This is without active wi-fi, which I can't access for the settings!) I'm not certain that it's trying to connect online, but that's my only explanation for why my google credentials aren't working.
I was hoping I could use ADB to reset the PIN again, but ADB doesn't appear to recognize the Nook; maybe it's not opening up the device to USB until it gets unlocked. And ADB Wireless is something I can't even access until I get past this!
I'm currently on the road so I can't go back to my home wi-fi... and I'm not even sure that the nook would connect to the home wi-fi anyway.
At the very least, I'd love to find out how to boot it in recovery mode, maybe re-install and re-root everything. I've seen a few posts online about rebooting in recovery mode, but nothing consistent.
Any suggestions?
First of all, I would like to point out that the XDA Developers website has made this problem harder than it needed to be. This post is originally from Stack Exchange, but people said I would have more luck here with this problem. But every little thing I do it a problem. Try to use a proxy on the website? Nope. Try to post this in the Samsung Galaxy S7 section, where it's SUPPOSED to be? Nope. I know it's all to prevent spam, but I mean come on. Be a little lenient here. Anyways, I'm done with my rant. Back to the post.
I have made the mistake of trying to root my phone. Which is fine, but it's a lot more complicated than I thought it was, but since I have asperger's, once I start something, I feel like I have to finish it.
I have a Samsung Galaxy S7 (SM-G930U) with Sprint. I've heard that these phones are EXTREMELY difficult to root. Some even call it impossible. But I can at least try.
I ended up getting tunneled down a endless loop of tasks to complete before I actually root my phone, for preparation. One of the things I must complete is I have to install a TWRP Recovery Image in case of failure. But in order to do that, I have to unblock the bootloader.
To do this, I am using Platform Tools, with includes ADB (Android Debugging Bridge), and Fastboot. I connect my phone to my PC via USB cable, open the CMD, and type:
adb reboot bootloader
Once I do this, my phone reboots into the bootloader, just like it should. Normally, the next step I would take would be to type in:
fastboot oem unlock
When I do this, I am left with the message:
< waiting for any device >
I'm assuming that means that it's not detecting my phone at all. It's odd though, because it was able to detect my device perfectly fine whenever my phone was booted normally, but when I go into the bootloader, it doesn't detect my phone anymore.
After hours of searching around the internet, I found that a potential problem could be the drivers of my phone that are installed on my PC.
Sure enough, if I open up the Device Manager, when in the bootloader, under Universal Serial Bus Controllers, I found the driver "SAMSUNG Mobile USB CDC Composite Device", with a little yellow arrow next to it on the icon.
If I double-click on the entry, in the "Device Status" box, it will say:
This device cannot start. (Code 10)
An invalid parameter was passed to a service or function.
Code 10 means that Windows is saying "There's a problem, but I don't know what." And well, I'm stumped by this.
The drivers work perfectly fine if I'm booted normally, which is why I'm confused. In the meantime, I'll continue my rampage across the internet for a solution to this problem that actually WORKS.
If you're wondering, I using Windows 10.

I am having similar problems with my Galaxy S7. In order to make any significant changes, the bootloader MUST be unlocked FIRST. Hence, the dilemma, if you can't make changes without an unlocked bootloader, and you can't unlock the bootloader, what can be done.
As far as I know Samsung devices simply don't have no fastboot support. Refer to Odin flashing tool instead.
Hi all,
:crying: - Looking for a way to get my Mi Note 2 back to life!
This device has never been unlocked or ROMed before (although it has been re-flashed successfully via Xiaomi's own pushed updates).
It is running MIUI 10.0.something (cannot access menus to verify exact).
The problem
----------------
I did a standard factory reset on the phone.
Once restarted, it takes you through the normal setup screens such as 'language', 'region', 'wifi network' after which I am given the option to select "copy your data from an old phone" or "set up as new", no matter which I select, my phone goes to the next screen which shows "Checking for updates". Here it stays - endlessly...
What have I tried?
----------------------
I have tried a different wifi network but it does the same.
I have also tried selecting "copy your data" instead of "set up as new" but it does the same.
Thoughts
------------
I thought I would try to install a new stock ROM to see if that would fix the issue. However, in order to unlock with the Mi bootloader unlock tool (and then use their flashing tool), apparently to do this, I need to enable something under developer options - clearly impossible when I cannot get to any android menus.
The phone *can* be re-started into the fastboot screen but does this help me at all?
On the MIUI website I noticed the following in the tips and tutorials forum: How to install a MIUI update without unlocking the bootloader: https://en.miui.com/thread-3852597-1-1.html
The above got me slightly excited before I realised that I have no way to place a ROM into the ‘downloaded_rom’ folder in the internal storage of my device (as the article instructs). Note that the reason for this (on my phone at least) is that although a Windows explorer window does open when I connect the phone to my laptop, it is empty (i.e. you cannot see any files/folders in it). BTW - I know what causes that specific issue as that bug was present in the device ages ago - basically, the phone seems to default to be in USB charge mode and in order to see the folders in Windows Explorer, you have to go into developer options and manually change the USB mode and then change it back to MTP mode. Once that is done, you can see the files/folder structures. However, I cannot get to any developer options as I cannot get to Settings at all.
What can I do?
------------------
So my burning question is this: How can I re-ROM this theoretically 'working' device, given the above constraints?
Is there any way to do anything while the phone is in the fastboot mode perhaps?
Is there some method maybe used to recover a bricked device that I could employ here?
Thank you for any help offered!
Cheers!
I bought a used Oneplus 5 phone, but every time I start it, I get this warning from Google that the bootloader is unlocked. So I tried to lock it again, but it always fails because when I enter: adb devices , the device is not displayed. I have already tried several articles from the Internet, including one from this forum, but without success. The device is only shown in the list when it is normally on.
i have now made it. The device was not displayed in the list, but I was finally able to lock the bootloader. The problem was apparently the Onplus driver from Windows, so I uninstalled it and installed one from the Internet.Reconnected and it did not get stuck waiting for the device.
I think I have an unsolved problem. I know it doesn't exist, but it's very hard to find it.
I know it's not the Plus, but the Model is the Moto C XT1754 (NAMATH) Android 7.0 Nogaut - NRD90M.060
And there is no specific topic for it, but they are very similar and I thought I could post it here.
It's a very complicated problem, so I'll explain in detail what happened and why I had to come here to solve it.
(translated)
- STARTING:
I installed a TWRP through the app, without unlocking the Bootloader.
Whenever I turned it on, at boot still, the message appeared:
'red state
Your device has failed verification and may not work properly
Your device will boot in 5 seconds'
But it called normally.
I installed 'Magisk Manager 24.2' by zip and app afterwards.
I activated 'Zygisk' and in DenyList I activated/hidden from Google Play Services completely. All.
I restarted the smartphone and Sitema started having numerous errors. Most of the apps that I opened, closed with error, and other apps in the background too, mainly Google Play Services.
I tried to solve this but I couldn't because the smartphone was unusable.
I decided to format by TWRP.
But when I tried to restart the device, I always entered TWRP and continued that message in Boot ('Red State Your Device...')
I decided to reinstall Stockrom from Moto C XT1754.
When I tried to install Stockrom through flash_tool, I couldn't.
It always gives error.
'BROM ERROR : S_BROM_CMD_STARTCMD_FAIL (0x7D5)
[BROM] Can not pass bootrom start command! Possibly target power up too early.
[HINT}:'
or this one is the most common:
'BROM ERROR : ?? (0x1)
[HINT];'
I even tried installing a Custom Rom via Sdcard , 'Viper-namath-20171206-Coral-v3.1.1-UNOFFICIAL' with the GAPPs, etc.
I can install the ROM. (but the GAPPS gives an error at the end of the installation) 'open_gapps-arm64-7.1-micro-20220215'
But I think this case is because it is not installing the Custom ROM correctly. (Because of the Locked Bootloader? Maybe... I'm kind of a layman on the subject)
Because when I restart the device after installation it goes back to TWRP.
I can't get into Fastboot mode with the command by the buttons on the device, only by TWRP when I access 'Reboot>Bootloader'.
Reboot and go to fastboot (Black screen, down there written '=> FASTBOOT mode...'
I've already tried to recover/rescue the device by Motorola/Lenovo's 'Rescue and Smart Assistant'. But when I try to rescue it (with it connected to TWRP) it asks to accept the message to enable USB debugging.
But I don't have access to this window through TWRP.
Here comes the big question, why I am not able to solve my problem:
I think my 'USB Debugging' was off/disabled before I erased everything (formatted).
I'll try Stockrom's Flash through TWRP to see if it solves the problem, but I don't think it will.
I think the problem may be with the 'USB Cable' as well. He's old. I tested with a non-original USB cable that I had to see and I can't either, the errors persisted.
I plan on getting another original to test as well.
Just an observation.
My device is being recognized as 'USB MTP Device' (under 'Portable Devices')
If anyone can save me, I'd really appreciate it!
Thanks in advance for all the help! Every opinion matters!
And when I give the command 'ADB Devices' my device appears 'unauthorized'
'ZW3223CGWK unauthorized'
