Which Nexus device do you have? You can restore your device to working order by flashing the appropriate Nexus factory image for you device found here , using fastboot (If you don't have fastboot setup on your computer this is an easy way to install it). Let me know if you have any questions I'll be happy to answer them for you.

Have you tried reflashing recovery via fastboot? If you see the Google logo it's trying to boot.
Reflash recovery via fastboot and reflash your rom of choice.

I'd tried and didn't work either, but i was able to get to the bootloader screen. I can't get my computer to see the phone while its in the bootloader screen.
Maybe you could boot into recovery from the bootloader and use a nandroid backup of some sort?

I can't get into recovery from bootloader, when I click on recovery, it looks like it's going to boot but nothing happen. I leave the phone on over night and nothing happen.
Ah...no worries..
stay in ur bootloader.
download a clockworkmod recovery image and cd into the directory u r in.
Perform the following commands if you ALREADY have a recovery img installed:
1. fastboot erase recovery
2. fastboot flash recovery _____.img (the blank line is the recovery img name)
3. reboot into recovery and perform ur nandroid
If you DON'T have a recovery img installed, then skip step 1

Soft Brick..no USB to help
Nexus S 4g is not connecting to the mobile network. Because of this I am trying to go back to the Sprint stock firmware. USB is properly charging my phone, but I'm unable to have the device enumerated by my pc. I've tried multiple cables, OS's, and PCs. USB is not enumerated even in the bootload state.
I have reverted to a backup when everything was working, but I still have the same problem with the network and USB.
WiFi works so getting new firmwares from ClockworkMod is an option, but going to CM7 did not resolve the problem.
I've read the forums and not found any solution yet. Has anyone heard of this before? Are there any options I can still try through software?

NEXUS 5 stuck at Google logo

Hi Guys,
After some cleanup in CMW i accidently format EVERYTHING. (formatted all single option in CMW, afterall a bad idea) So now i'm stuck at the google logo.
Now i have the 4.4.4 KTU.zip on my computer. Can i flash this via ADB sideload (as a renamed ''update.zip''? Or can i just copy the .zip file to my Nexus from a computer?
I'm @ work so i;m stuck guessing what i must do to get this thing work!
Thanks in advance guys
i dont know what it is, but if its a rom, sideload then flash away. your phine is empty right now, no rom or anything. you need to put something into your phone(sideload) then flash it.
Yes, the whole zip file is the stock ROM in a zip file.
Luckely i can't login as administrator here or else i could get my device working here
Thanks!
Why not just start the bootloader (fastboot mode) and execute the flash-all.bat? It'a the 'official' way to completely restore your phone. I've done it several times and it always worked great

get the factory image here, unzip it, and run the flas-all.bat. make sure fastboot works correctly. it will flash your phone back to stock.

Phone stuck on boot animation, won't sideload

I unrooted phone to update to Android 5.0.1
Wiped data & cache and tried to reboot but phone won't load past boot animation
I have tried everything I can find online. Phone appears in Device Manager as Android Device, but does not connect to PC when in command prompt.
adb devices shows no devices
when I start phone in fastboot, then recovery mode, I can select to install a file via ADB
when I choose this, and run adb devices in command prompt, it then shows a sideload device
but when I go to load a file, it gives me the same error every time:
E:footer is wrong
E:signature verification failed
Is there anything I can do? Please help! Thanks.

What recovery have you got and what file are you sideloading?
All you have to do is restart the phone in bootloader and make a fresh install of factory image via fastboot.

I'm not sure unfortunately... Is that something I can find out from the Fastboot menu?
I was trying to sideload a factory image 5.0 or 5.0.1

You can't sideload a factory image. You must use fastboot.

How can I make my Acer read Nexus 5 to install factory image via command prompt?
It comes up in Device Manager, driver seems to be installed fine, as Android Device but does not connect properly (no devices listed in "adb devices")
You use fastboot in bootloader if you want to use factory images.

Wow thank you, your thread suggestion was exactly what I needed. I did not know the difference between ADB & Fastboot.
Silly mistake but one that I couldn't solve through several hours of internet searches yesterday. Thanks for your time and insight, have a great day

Can I still install any recovery(CWM or TWRP) after I have forgotten my password?

My question is: Is there any way that i can install any custom recovery now, when I am locked out of my phone, so I can try Method 7 from this post . I have enabled USB debugging, but for some reason, my device is unauthorized from executing adb commands.
I have Xiaomi Redmi Note 3, and have forgotten its password. I have tried Method 2, 5 and 6 from this post, but to no avail.
I tried method 2 and 5 which requires ADB to be installed, but I was not able to access my phone. I have USB debugging enabled and my phone is not rooted. When I tried to run the following code:
Code:
adb devices
adb shell
it showed that my phone is unauthorized and error: device unauthorized This adb server's $ADB_VENDOR_KEYS is not set
Here's the screenshot:
When trying method 6, I had to change the path of ADB driver because the file I downloaded from the post, had its own ADB driver which clashed with my already installed ADB driver, but even after that, it again showed the above error. Here' the screenshot:
Finally I want to try method 7 from the above post, which requires custom recovery to be installed on the phone, is there any way now?
Though it seems now that the I have only one option left and that is to factory reset my phone, but if , there is any other way by which I can bypass my lock screen, please please please inform me.
Of course you can. Just boot your phone into fastboot and do "fastboot flash recovery <recovery image name>.IMG" and you'll flash it. And you can't access the adb because your screen is locked... This is how companies prevent phone hacking
So flash custom recovery, backup the /data , factory reset and after resetting restore the /data backup. And you're good to go. I suggest you using TWRP, because I use it and it never left me hanging Keep me updated.

OK... So first boot into fastboot. When you've done that, connect It to your pc with usb, download fastboot package from somewhere on xda(you'll find it).
Open command prompt "CD" to the directory where your fastboot is located in, put recovery image in the folder where fastboot.exe is and type "fastboot flash recovery <recovery file name>.IMG". I'm gonna update this answer in 2 days, when I get to my pc, so try to do it by these instructions, if something isn't working, comment and we'll resolve the problem. If something isn't clear, just ask. Keep me updated.

Can unlocking my bootloader somehow brick my phone?
Everything can brick your phone. Updating my lenovo phone with official update hardbricked mine... But yeah, it can.

Please help me, I just got the phone.

Thanks so much, I really appreciate your response. I read your thread, my question is that:
Will my device be connected to the system while I run the command scripts?
Also the fastboot in stock recovery mode is not running!
Can anyone help with this

Fastboot deals with device's bootloader, hence to work device must got booted into its bootloader
ADB deals with Android's filesystem, so to work USB debugging must got enabled on device
If you boot device into Recovery then an app gets started what offers you a menu where you can select specific actions from to get applied to the device in hope some common problems get fixed or that device's Stock ROM should get re-installed.
