[HELP PLEASE!] Forgot encryption password cannt recover! - Nexus 4 Q&A, Help & Troubleshooting

Hello XDA
First off let me tell you what im running.
Nexus 4 running Cyanogenmod 11 with USB debugging turned off.
So my I bought this phone used and allowed my brother to install a custom ROM on it. I also gave him the OK when he asked me if he can encrypt the phone. (No problem, what can go wrong right?) Well it turns out nothing did go wrong but the only thing is when I went to go change the password I only changed the SCREEN LOCK password not the encryption password thinking they were the same. When i went to go boot up my phone today it asked for the encryption password but wont accept the lock password. Went to ask my brother for the password and he said he forgot because he had already told it to me.
Now im stuck with a possible broken phone =[
Steps I have tired: after painstaking hours on google and XDA looking for an answer
- I have tired to download TWRP but cant install the zip file because i cant get the fastboot to show USB FASTBOOT
- I have tired recovery mode with ClockworkMod Recovery v6.0.4.7 and tired the cwipe data/ factory reset with no luck
Can someone please guide me in the right direction on what I should do to fix my phone?
Many Thanks!!

Flash the factory image in fastboot. It'll wipe the device and return it to like new. If you don't have fastboot Google 15 second adb install xda

I installed the 15 secs ADB but when i run the program, it quickly shows a DOS screen then auto closes. Would this still work with USB debugging turned off on my android?
EDIT
the phone doesnt even show up on my device manager, after typing "adb devices" no devices show up. I have tired to manually install the drivers but it wont show up on device manager

You can just factory reset the phone to remove encryption. Boot the phone into recovery mode. When you see the "no command" screen hol vol-up and tap power, then you can wipe the device.

Please help! Nexus 10 stuck on google X during failed root :(

Hey guys
I tried the one-click root toolkit for mac from android rootz.
Something apparently has gone wrong during the root and I got some error messages and it didn't proceed. Next thing I know the nexus is stuck on google X logo and that's it. It won't load. I tried to recover through the recovery mode a couple of times but now I get the red warning sign when I go into recovery mode. This is only the second day I've had the nexus for. I feel like crying. Please Help
When the red sign appears press the volup down buttons and power button randomly until you get into recovery then factory reset
My 7 and 10 both did that. Just hold power until it turns off, then boot a recovery, wipe everything except system and reboot. It'll come up ok.

I'm having the same issue. However, the recovery I have installed is the non-functional CWM. So I can't factory reset. (I managed to once before CWM bombed, but it didn't change anything.)
I've tried several options via the toolkit. After fighting with the app all day it's finally wound up just saying it can't find adb? (I have a growing dislike for this app and have since uninstalled it.) Adb is right where it belongs and seems to run fine from cmd.
I also can't seem to flash anything via fastboot for some reason. The device throws "failinvaild id command" and fastboot immediately crashes on my laptop.
I managed to get it unlocked. However, I'm unable to flash anything to straighten it out...
Any help would be great.

Thanks for the info. My situation wasn't quite the same as my CWM was the real issue, which wouldn't run long enough to allow for the factory reset boot-loop solution. Kept at it and managed to get CWM to finish the individual formats/resets one at a time.
With a now bootable device, I'm off to replace the recovery... Thanks again.

locked bootloader wont unlock

Hi everyone. Here is the deal im having with my nexus 7 (not the 2013 model) with jop40d.zip. The person I purchased from didnt tell me it was soft bricked. It seems as though he tried to root it but failed while at the same time relocked the bootloader. So I've tried almost everything in my mind to get it back to normal. It wont let me adb sideload the stock rom it says "installation aborted" or any other rom. Also when i boot up it goes directly to the bootloader which gives me the options start, restart bootloader, recovery mode, power off. start obviously does nothing. restart bootloader just for some reason turns the device off, recovery mode takes me the caution sign where i can adb sideload or factory restore. factory restore hangs and doesn't do anything then shuts off. adb sideload always fails when loading up the zip files. i factory restored the cache. I'm not sure what to do anymore. I spent a fair amount of money on this device but now it all seems like a mistake. Can anyone who has fixed this issue help me out? I would deeply and greatfully appreciate it.
-Cheers

also I wanted to add. I have the android sdk installed and all drivers installed properly. as well as adb/fastboot.
Stop trying to use adb, follow the sticky at the top that says flashing a factory rom using fastboot/return to stock. If you can't type fastboot devices and get a serial number return then the drivers are not installed properly.
Sent from my Nexus 7(2012) that has zero issues.

[HELP] Nexus 4 Stuck in Google logo NO ADB NO Fastboot

So i was having problems with PA 3.99 so i decided to check out Carbon and i decided to do a "flash to stock + lock" before hand to have the phone completely wiped. but i ran into problems when the toolkit i was using (Wug's Nexus Root Toolkit v1.7.2) made me use twrp to re wipe the phone i guess i must have deleted a system folder or something.
Now when i turn the phone on it stays on google logo and no toolkit recognizes it saying no adb or fastboot device found
Can Anyone please help me? I really need my phone, i never meant for this to happen.
sorry if this problem has been solved before i looked and couldnt find anything.

hold power + volume button to go to bootloader you can perform all adb commands from there for example "adb reboot recovery" etc.
if your device is on google screen just press and hold power button for 10 sec.

Bootloop and cannot boot into recovery

Hi Guys,
My nexus 6p is running stock firmware with no root or any custom rom or recovery.
Suddenly, while i was browsing the internet on my phone, it restarted and went into bootloop through the google logo.
I tried to boot into bootloader and then tried to go to recovery mode from the bootloader but it went again into bootloop.
I then tried to download the latest image and tried to flash it but was surprised that i cannot unlock the bootloader except from inside phone settings (if it was working) which is very inconvenient.
Any thoughts as recovery mode is not working to be able to reset to factory settings and cannot flash any rom or original firmware as it's locked.
Are you saying that you did not have OEM Unlock turned on or have USB debugging enabled in developer options? Is your phone recognized by ADB when you are connected to your PC? When you enter the Bootloader, can you select ADB Sideload with bootlooping? I have been trying to help a couple of people with this issue for the past few days Also, when you enter the Bootloader does your 6P show DOWNLOAD MODE is Disabled?

Try this:
Press and hold the POWER BUTTON + VOLUME UP and continue to hold them. Watch the screen. Does it still continue to bootloop or does a screen show up that says "NO COMMAND"? If the NO COMMAND screen is displayed, let your device sit without doing anything. There are some devices that have sat at this screen, rebooted on its own and booted back into the OS. Let me know what happens.

It showed no command once and then rebooted into bootloop again.
Tried it again after and it did not show no command. just went into bootloop.

Yes. i left it as you mentioned and it went into bootloop. Even the one time i managed to get it in recovery mode and made factory reset and wipe cache partition. I did not get it to be detected by ADB as debugging was not enabled in the setting menu.
This recovery mode is really useless if you cannot start the phone. Its supposed to be RECOVERY mode but its completely useless.
Previously, you could just unlock the bootloader and flash new image. Now it must be enabled in the setting in a phone that does not even work.
The only option you have with a locked Bootloader is to attempt to ADB sideload a zip or OTA and that's only if you could select adb sideload from recovery. When you open the Bootloader does your device show that DOWNLOAD MODE is DISABLED? Also, have you checked to see if you can issue any fastboot commands while in the Bootloader?
Sorry, I asked about the Download Mode showing disabled again. I've read so much about this and so many threads I forgot. Try this for me:
Open the Bootloader
Type this fastboot command:
Fastboot oem ramdump enable
Fastboot reboot Bootloader
Power down
Power up to the Bootloader
Try selecting adb sideload again and see what it does.

You are asking the same questions again. YES, download mode is disabled.
after the first command, it tells me "locked device to enable ramdump"
I tried adb sideload but did not work because its not enabled in the phone settings as i already mentioned before.
I apologize for asking the same questions. I got confused on which thread I was posting in. I have been trying to help someone else with the same issue.

Adb sideload won't work in bootloader mode, only in recovery. The only thing that will work in bootloader mode is fastboot but seeing as the bootloader is locked (with no way to unlock it) you can't use fastboot. If you can't get into recovery there's nothing you can do except send the phone for repair.
But how can anyone troubleshoot any phone if the OS is not working. This new way of security is simply impossible.
So if the OS fails like my case, i am screwed.

I'm not sure what you mean by new security, this has been standard fare for some time now. I'm sure if your phone was stolen you'd be thanking this security feature because it'd mean that the thief couldn't possibly access your data.
People in the know usually go into the settings menu and tick the "allow oem unlocking" box even if they don't plan on unlocking the bootloader at that time, there's a slight security risk but it's insurance against situations like this.
And what you're saying isn't entirely true; even if the OS fails the phone can usually still boot into recovery which would mean being able to revive it via adb sideload. What you're experiencing is relatively unusual, not being able to boot into the recovery as well as the OS means you're basically screwed.
If there's anything to take away from this it's that electronic devices fail sometimes. If you can handle the security risk it's worth ticking that box in the settings menu, or even completely unlocking the bootloader, to give yourself some insurance against these rare situations.

My phone just did the same thing yesterday morning. I'm currently waiting for Hauwei support to get online because Google wont do anything for me since it's been about 13 months (Google only offers a 12 month warranty). Hoping for the best, but without being able to access Recovery makes me very doubtful.

You both might want to take a read of http://forum.xda-developers.com/nexus-6p/help/figure-brick-t3450921 - it has many people who have experienced the issue you both have. tl;dr - you'll probably need to contact goog/huwaei for a replacement.
Had the exactly same issue the day before yesterday, tried every possible way to flash different versions of images, none worked. My warranty expired 2 weeks ago, so both google and huawei told me that I am on my own for this.
Wow.. I feel for you all. I've had the exact same thing happen some weeks ago, phone freezing, then reboot, then couple of days later bootloop, then able to flash and reinstall, then after one final bootloop with the phone unable to 'take' the flashing through recovery, etc, etc. I've been playing with xda since the days of Froyo and that was the first time I had to send a phone back under warranty.
I was just about to try to manually rebuild the whole partition system at the block level but I'm glad I could send it for repairs. You might have a chance if you go as low as that. Good luck
* edit * I got the TWRP to stick by flashing it in Fastboot a couple of times in a row at that time, then I was adapting a Linux guide on reformatting and repairing drives partitions and all that through an adb shell.I did not get it to work yet before sending it, though.
