Help bootloader locked - Nexus 5 Q&A, Help & Troubleshooting

I flashed miui ROM coming from purity to test it, but now I'm not able to restore my backup because I can't access to cwm.. On the bootloader page it says that now my bootloader is locked.. Why? And what I have to do now?

go into your recovery, not bootloader.

Edit
Watching better I saw that my BL is unlocked still.. So I guess that I just have to reflash cwm @adb right ?

if you go to the android laying on its back, that's the stock recovery. all you have to do is flash a custom recovery, i recommend the twrp recovery, not cwm.

I'll second the recommendation for installing TWRP instead of CWM. It's a much nicer interface overall.

Are you rooted? If so you could install BootLoader from Play, press unlock, and then flash a custom recovery to restore your backup.

Use an app called "Flashify" to flash either recoveries mentioned. Super easy

We currently can't flash any recovery (except for stock) on the 4.4 bootloader. If you want to use CWM or TWRP, you'll need to downgrade to the 4.3 bootloader first, or wait until we have working recoveries on 4.4 BL for our MotoG's.

How to Know before flashing custom recovery

Hello I have a chinese opo with cm11s installed.Whenever I run bootloader unlock it says time taken 0.00 sec
okay.Now Im not sure maybe the seller has unlocked the boot loader. Is there a way to know before flashing custom recovery?Thanks.Will flashing custom recovery on locked bootloader will brick my device?

No it will not brick your phone. If your phone's bootloader is locked, it will simply not let you flash a custom recovery. If its unlocked, then it'll flash the custom recovery.
Ensure that update CM recovery in developer options is disabled (to enable the menu, tap build # 10 times in about phone and then go back into developer options)
Thanks it worked,I was right it was already unlocked

that guy used cwm... it seems that that recovery caused his brick.
i think you should use twrp or philz one...

Twrp disappears 5.0

I have unlocked boot loader, but when I flash twrp through command prompt it works that one time I boot into recovery from boot loader but afterwards it reverts back to stock recovery. Any help would be appreciated!

What worked for me is to flash TWRP 2.8.1.0 in fastboot and after booting up flash 2.8.2.0 with Flashify.

Thanks! So what you suggest is to flash 2.8.1.0 flash the new beta of superuser, then flash the new version through flashify?

Thats what did it for me
If you delete /system/etc/recovery-from-boot.bak (or similar) the recovery should stick also when flashing via fastboot and using TWRP 2.8.1.0

Problem with TWRP

Hi guys.
I installed via flashfi the TWRP on my nexus with android 5, original rom. My bootloader is unlocked.
However, when trying to enter the recovery mode, appears the initial screen of TWRP and simply back into the system. What might be happening? Its fix it? And is to return to the default recovery?
Regards,
I flashed 2.8.1 using fastboot... Try fastboot and see if it works

Root 5.0.1?

Hi I was going to use chainfires method but the best the web page it only sates 5.0 with the build number LRX210- which is different to 5.0.1?
Is there any way to root then?

of course there is a way to root 5.0.1.
use fastboot to either flash a custom recovery (TWRP is probably your best bet), or use fastboot to just boot into the custom recovery without flashing. Either way, once your in recovery, flash SuperSU (download here http://download.chainfire.eu/641/SuperSU/UPDATE-SuperSU-v2.40.zip)
done and done.

You sir are very wrong, you cannot flash that zip in recovery because it no longer works with lollipop... (Sigh)
PS. I have a custom recovery and unlocked boot loader so your suggestion are invalid

actually, it does work. with 5.0.1, I'm rooted. Except when I flashed 5.0.1, SuperSU v2.40 hadn't yet been released, so I rooted with SuperSU v2.37, and then updated via the playstore when 2.40 came out. but it definitely works with Lollipop.
p.s. you need to have an unlocked bootloader to install a custom recovery (which is what I suggested doing). So in fact, my suggestion is completely valid and 100% relevant. In fact, I had assumed that you already had an unlocked bootloader when I posted.

Your point is again invalid and 100% incorrect- I have just tried and it has not given Me root. I have to manually re-root not flash the zip. See attachment

yes, and the way to "manually re-root" is to flash the ZIP in a custom recovery. You the app installed, but not the SU binary. So flash it in TWRP.

CF Auto Root and flashing the superSU2.40.zip in recovery both root android 5(0.1/0.2). Did it myself and confirming root access.
You can root with the same chainfires files for 5.0, and then you can update supersu and twrp

It astounds me how you have the guts to ask for help - then someone gives you an answer that is completely right and you do a hard six and blatantly flame them for trying to help you.

Crazy. Done it to me a few times. I even decided not to help him ever again some time ago, then took pity on him yesterday or the day before and the he did it AGAIN!
He's just a school kid, but you'd hope he would learn from his attitude, but apparently not.
What's worse, is he isn't even picking up the knowledge that people give him or reading the stickies. He's been Here pretty much a year in the n5 forum and cannot even be bothered to.understand the basics. Asks the most basic questions every time.
