Secure boot is enabled on all Nexus 4's, and you cannot disable it. By the way, Secure boot has nothing to do with the lock state of the bootloader -- it has to do with the secure boot chain of the AQP8064 chipset.
Unlock the booloader using "fastboot oem unlock" and then flash the factory images. See here.

If simply flashing factory images, an unlock should not be necessary. Is customer wanting you to try and preserve data?

Thanks for the answer but the wierd problem is that after I unlock the bootloader and try to flash any thing I get":
sending 'bootloader' (2188 KB)... FAILED (command write failed (Unknown error))
Click to expand...
Click to collapse
and after I reboot it shows that the bootloader is locked

I managed to boot into twrp recovery but no screen by "fastboot boot recovery.img" and I get adb access.
ant thing I can do from here ?

You are seeing a black screen because you are not using the correct command. It should be: fastboot -c "lge.kcal=0|0|0|x" boot recovery.img

Two options before we decide it's hardware.
Procedure #1:
1) Download the LATEST version of fastboot.exe from here and extract it to C:\android.
2) Download the latest factory image from Google's dev page and verify the checksum with what is posted on the website.
3) Extract all the images from all the .tgz, .tar, .zip files within and put the 6 image files in C:\android
4) Reboot your device into the bootloader and plug into your PC.
5) Open a command prompt in that same directory and type the following commands:
Code:
fastboot oem unlock
fastboot reboot-bootloader
fasltboot flash bootloader bootloader-mako-makoz20i.img
fastboot reboot-bootloader
Does that work? If so then continue with flashing the radio, boot, system and recovery images. If not, then go to procedure number 2:
Procedure #2
Follow the instructions in this thread.

Cant make the NPST recognize the phone ;\

Any thing else to try ?

[Recovery][H830] Team Win Recovery Project for the LG G5

Team Win Recovery Project 3.0.2
WARNING: The stock boot image has dm-verity, which prevents you from booting if you swipe to enable system modifications!
SOLUTION: Flash a root such as SuperSU or phh-superuser. You can also flash no-verity-opt-encrypt.zip.
NOTICE: The LG G5 H830 currently has flashing locked!
You will need to use a tool to get around this limitation. At the moment, Team Win nor myself cannot provide anything for this.
The community, and user @tungkick has however provided an alternative method of flashing, which can be done via a full firmware flash using a TOT file.
See here for instructions: http://forum.xda-developers.com/tmobile-lg-g5/development/root-h830-t3384526
A message to those with other variants of the G5:
Should there be a time where your flashing mechanisms get cracked, simply mention my name on this thread or via private message and I would be happy to create a thread with TWRP for your device.

I'll be able to test at about 7PM tonight.

I'm interested in assisting.

i may be able to do it in a few hours as well but until then, I wanted to ask, is it not possible to fastboot boot <img> without flashing it? Only asking because that's what i've been doing lately with my huawei watch for testing without overwriting my recovery.

tried it get unknown command

I wonder if we need to put the phone into download mode for it to take the flash... Not sure how to get there. The old hold volume up and insert usb cable trick from the G4 isn't working for me.

Awesome, anyone else? Looks like they really did lock it.
fastboot flash returns unknown command
fastboot boot returns unknown command
It seems that attempting to send an unsigned boot image returns in unknown command. I'm assuming that's just a generic error code returned by qualcomm secure flash due to invalid signature, rather than the command actually being unknown. (maybe fastboot does not have "invalid signature" return codes?)

im getting the same cant flash it apparently they put us in a cage and only unlocked one out of two locks

fastboot flash recovery twrp.img didn't work. Fails with the unknown command error.
fastboot flash:recovery twrp.img doesn't work because it doesn't like the syntax.

mhhh, very strange, it seems a "custom unlocked" bootloader like Meizu products....
I hope to be wrong

But the command to unlock bootloader hasn't changed? In the 6P its "fastboot flashing unlock"
https://source.android.com/security/verifiedboot/verified-boot.html

No visible recovery partition available
Take a look at this post, and see where would recovery be hiding (actually hiding, or new name)

I was already unlocked and tried to run that command earlier and it didn't work at all, as in, didn't like the syntax at all. I updated my fastboot and ran it just now on my already unlocked device:
Code:
fastboot flashing unlock
...
(bootloader) Device already : unlocked!
OKAY [ 0.020s]
finished. total time: 0.021s
Locking / unlocking with the newer fastboot won't yield any different results will it?

need to dm-verity OFF

Phone Stuck | Need to recover photos from internal memory

Hi All,
Due to in ternal memory full, suddenly my home button stopped working and notifications were not appearing. I tried and followed advice written in one of the websites:
"f you didn't enabled developer settings and usb debug prior to the defect, you can create an icon to call this Activity using Nova Launcher.
After installing it and launching, long press home screen, select widgets, swipe right to find Activity icon, place on empty space in your home, search for setup wizard (it changes accordingly to your native language), select .SetupWizardTestActivity and voilá."
But, now my phone is stuck in SetupWizardTestActivity loop. I desperately need to recover my photos and other data on internal memory.
Please suggest.
Additional Info:
Using Moto X play (updated to Marshmallow)
Bootloader is unlocked

Can't you just boot into safe mode and try if that works.
Boot into Safe Mode
With the phone on, press and hold the power key until the on-screen “Power off” option shows up.
Long press on the on-screen button, and select “Boot into Safe Mode.”
or if you have an unlocked bootloader you can flash TWRP and use the build in file manager to transfer the files to your sd.

If bootloader is unlocked then recovering data is easy, I guess you have TWRP recovery if not flash twrp then pop in a sd-card boot into recovery and copy everything to the card. Done.
Edit: the above comment says the same thing, I had not noticed that .

While flashing TWRP recovery, I am getting the following message in CMD:

is the bootloader unlocked, did you input the code to unlock??just checking

Yes. Bootlader is unlocked with input code to unlock.

I guess adb is not authorised then. when the phone is in setup wizard connect it to pc and type 'adb devices' there will be a pop-up asking you to authorise adb. select it. the try to flash recovery again .

"adb devices" is not working during Setup wizard.
Do you mean to say that I run fastboot boot <enter twrp name> during setup wizard?
Also, alternatively, will flashing a rom without clearing user data help in any way?

adb and fastboot are different things and are unrelated to each other. He doesn't need adb to flash the recovery.

Hi,
I tried re-unlocking the phone using code and got following message:

FAILED (remote failure)
finished. total time: 0.008s
Any workaround?

unlocking bootloader will wipe the data in your phone.
I thought you had unlocked.
what is the problem when you try to setup the phone ? or skip the setup

best option now is flashing the firmware manually without wiping data.

RSD lite needs windows 7.
Yes you have to flash manually then using fastboot commands.

Just don't use the command to erase user data. Skip it. Open the zip there will be flashfile. xml/servicefile.xml open it , you will find the list of commands to run. Or the commands can be found here.

If you are on 6.0.1 then flash 6.0.1...better flash the appropriate region firmware.
There is a risk of bricking if you are downgrading and flash old gpt.bin and bootloader
As long as you are flashing proper firmware it's safe thoughi haven't done it but as you can see the comments I linked previously others have done it.

p9 lite stuck on huawei boot logo

My p9 lite is stuck on the huawei logo, its been a week now. it all started when I flashed a wrong update.app (i mistakenly flashed the rollback update.app while i was on b161)
now I cannot use the device anymore, i can only get to bootloader mode but cant flash anything
help

I had the exact same problem. I got out of that situation by rooting the phone, and re-flashing it.
However I already had the unlock code handy. If you don't have that then you are mostlikely f'ed.

My bootloader is unlocked yet I am unable to fastboot flash anything as i get errors.

HEY! I've done the same thing yesterday But now phone working great! I find the way
1. Download C432B160, Huawei Extractor and SRK Tool Huawei
2. Prepare your unlock bootloader code
3. Unpack UPDATE.APP by Huawei Extractor (You need files: boot.img, system.img, recovery.img, cust.img)
4. Go to folder SRK Tool Huawei -> Command
5. Put *.img files to Command folder
6. Put UPDATE.APP (Not extracted) on your sdcard in folder "dload"
6. Hold Shift + right right mouse button "Open the command line here"
7. Plug your phone in fastboot mode (vol- and power button then fast plug USB)
8. Type in cmd "fastboot devices" (Now you probably see your device)
9. Type:
fastboot oem unlock xxyourfastbootunlockcodexx
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img (that command takes 2-3 minutes)
10. Unplug Your device
11. Hold vol- vol+ and power button, it will install UPDATE.APP from your sdcard
12. Done!

I'm stuck at "6. Hold Shift + right right mouse button "Open the command line here"" I have no idea what to do

You have to hold the "Shift" button on your keyboard (under Caps lock), and click on the right mouse button in the folder. Then in the menu, choose "Open the command line here"

HEY! I've done the same thing yesterday But now phone working great! I find the way
1. Download C432B160, Huawei Extractor and SRK Tool Huawei
2. Prepare your unlock bootloader code
3. Unpack UPDATE.APP by Huawei Extractor (You need files: boot.img, system.img, recovery.img, cust.img)
4. Go to folder SRK Tool Huawei -> Command
5. Put *.img files to Command folder
6. Put UPDATE.APP (Not extracted) on your sdcard in folder "dload"
6. Hold Shift + right right mouse button "Open the command line here"
7. Plug your phone in fastboot mode (vol- and power button then fast plug USB)
8. Type in cmd "fastboot devices" (Now you probably see your device)
9. Type:
fastboot oem unlock xxyourfastbootunlockcodexx
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash cust cust.img
fastboot flash system system.img (that command takes 2-3 minutes)
10. Unplug Your device
11. Hold vol- vol+ and power button, it will install UPDATE.APP from your sdcard
12. Done!

You only think it's unlocked (yeah, it's showing Bootloader UNLOCKED) but no, it isn't. I don't know why, but you must unlock it first.

I'm no longer getting the error I mentioned but now my phone wouldn't respond to the three button boot... it gets stuck on the logo again and doesn't do anything. I don't think I have the correct firmware. I need for VNS-L22C636B101 and I cant find it anywhere :crying: my phone is done for

You have to flash custom oeminfo.img to debrand your phone (it's fully legal). You'll find it on htcmania

thanks but..

Yes, you can't flash C432B160 if your phone is branded by operator, the flashing will always end at error. Flashing oeminfo.img and Huawei firmware is fully legal and you don't loose warranty. And debranding is a good thing because (in future) you can download faster official Nougat.

okay

Alright so let me explain my situation properly (I'm a big dumb-doofy-doo so i'm not even sure if my phone is branded) I bought my phone off amazon last year and 2 days ago I made the mistake of trying to update it to Nougat using http://www.droidviews.com/update-huawei-p9-lite-manually-official-android-7-0-nougat-emui-5-0/ and the files for build number VNS-L22C636B360 however my build number is VNS-L22C636B101 (Huawei P9 Lite). using the first file called "update.zip" I tried upgrading but it said software update failed. I turned on OEM and tried using "update_data_full_VNS-L22_hw_spcseas.zip" to update. it worked but I don't think this was the full update as it rebooted and I was greeted by Huawei eRecovery which had three options: "Download latest and recovery" "reboot" and "shut down" so naturally I chose the first option. It however ended with "Getting package info failed". I tried it over and over but it didn't change. so this is where I because frustrated, and stupid, and factory reset my phone. it didn't make a difference. same eRecovery prompt (but did the reset take off OEM??) I took out my SD Card and replaced the Update.app with another one (I cant remember which I was sad but I definitely complicated matters more by doing this) and I came upon the same problem the person who made this post: stuck on Huawei logo. if I power it off it will vibrate and boot back up on it's own to get stuck on the Huawei logo thing (it wouldn't even do the pretty flowy smoke thing) so because of this it does not respond to the 3-button force update anymore idk why the only mode I can get it into successfully is fastboot mode but even after following the step by step answer I cant get it to respond to the 3-button force update (I also dont have the exact firmware for my build number) I did skip the bootunlocker steps because I dont have a product id or IMEI to generate a code from the Huawei website. in fastboot mode however it says "Phone Unlocked" and "FRP Unlock"
I dont know what to do... I think I need the firmware but I cant find it specific to my build number VNS-L22C636B101

First of all you must have your bootloader unlock code...
You wrote that you get error on flashing by fastboot probably "Command not allowed" because, your bootloader is locked (Yes it's only display "unlocked" I also got on that )
If you don't have code you can't do anything, sorry. You must send your phone to huawei store on warranty.
You don't have phone box?

ya

Ask your seller, hope you'll get a working phone

Mine was solved by booting to fastboot and did fastboot OEM unlock "unlock code" then fastboot flash recovery TWRP.img
Even though my bootloader was unlocked it worked

Help~ US LEX727, fastboot oem unlock-go failed after TWRP restore

A brand new LE Pro 3, LEX 727.
EUI Version 5.8.021S
This is what I did:
Enable the Developer Option. Enable OEM Unlocking and USB Debugging
boot phone to fastboot mode, then connect to PC.
> fastboot oem unlock-go
> fastboot format userdata
> fastboot boot twrp-3.2.1-0-zl1.img
The phone enter TWRP, then in TWRP, I did
(1) backup,
(2) wipe (advanced wipe, select system, data, dalvik/ART cache, cache)
(3) Restore using backup created in step 1
After restore and reboot, the phone back to original.
Then I did:
1. Enable the Developer Option.
2. Enable OEM Unlocking and USB Debugging
3. ReBoot Phone to fastboot mode (Volume Down + Power button) and connect to PC.
4. fastboot oem unlock-go
Weird, this time it failed:
C:\adb>fastboot oem unlock-go
...
FAILED (remote: oem unlock is not allowed)
finished. total time: 0.006s
How can this happen? How to fix it???
Thanks!

Roger, I thought that I messaged you earlier but I see that it wasn't posted. I just answered your PM
So check your messages
Edit: It failed, because you restored the locked emmc_appsboot.mbn
after you prepare the phone for unlocking the bootloader, make sure that you remove any passwords, this way you will not have any storage encryption issues.
