seeking solution for nexus 5 on bootloop with locked bootloader. - Nexus 5 Q&A, Help & Troubleshooting

Nexus 5 stuck in bootloop with locked bootloader ..Can anyone help me with procces to stock flash it? ? Thanks in advance

You can flash stock images without unlocked bootloader.

If you want to flash stock, you can unlock the bootloader, which will wipe all data, and flash a stock Google ROM using a script. You could also use the NRT: http://www.wugfresh.com/nrt/

That toolkit is handy for many uses. Glad I don't have to use it much. Still have it installed on my laptop just in case.

[Q] Flashing Real ics v6 to Sony Ericsson Live with Walkman

Hello!
I want to flash Real ics 6 to my lww with locked bootloader but can't! I mean, i tried like three times following the instructions step-to-step but I would always get stuck at the first boot( black screen). Do you know a way to flash it with unlocked bootloader and worked for you?
Would it be better to unlock the bootloader and install a kernel? But how do I do that? Fastboot? Flashtools? The only instructions on kernels is
1. flash via fastboot
and nothing else...
And, yes, you guesed it! I am a noobie! But how do I get to be a pro if I don't become a noobie first?
Thank you for your answers!

As I know Real ICS wants custom kernal. It is impossible to flash custom kernel with locked bootloader. So 1st you have to unlock the bootloader and flash a custom kernal.

did you follow the steps for locked bootloader in the Real ICS r6 Aroma installer? If not, with the steps to reproduce the problem u r facing, drop a direct message to Kobzaar (developer of Real ics). He will revert with the solution for sure

You don't need to flash a kernel, it is recomend for those who have the bootloader unlock, you just follow the steps in the post of the RealICS6 for the locked bootloaders.
every think work on this ROM?
1.Factory reset in cwm
2.wipe cache partition
3.wipe dalvik cache
4.Format /system (in mounts and storage)
5.Format /cache
6.Format /Data
Try this and if it doesn't work then i think it's only for unlocked bootloader mate...
I am also having the same problem. I tried a few times already & followed all the instructions. I have an unlocked bootloader, but I can't recall whether I am on a custom kernel right now (last remember flashing the cm9). Is that the problem? If so, what do I do? Flash a kernel using flashtool & then follow the steps? & which custom kernel do I flash? Can someone give me a suggestion?

Modified Boot Image Android L (5.0.0_LRX21P)

Flash in Bootloader (this is not a flashable zip)!!!!
Flash the stock root able rom, here available on xda.
Don't worry it's for our FLO device, just a name. Sorry, i was in a hurry.

Whats modified about it?
use this, if you want to flash the stock rooted rom via twrp etc...
if you use the stock one, your bootloader is locked after flash the stock rom

Incorrect mate, it's still unlocked after flashing factory images. I flashed factory files yesterday and I only lost root and recovery which I expected to happen.

It's just the latest bootloader.img, he thinks if you flash it separately you won't lock your bootloader before flashing the stock rom via recovery.
To my knowledge, nothing locks the bootloader, except you (via fastboot or a toolkit).
So i can install the stock image i downloaded from google and still keep root? What about recovery?
Sorry for noob question, i've only used custom ROMs in the past.
If you flash the stock L image with fastboot, you lose root and recovery but your boot loader stays locked/unlocked (whatever it was before).
To get recovery back, just flash it with fastboot.
To get root back, flash the boot image from the OP or a modified kernel like ElementalX and then flash SuperSU.
Done.

Fido Razr HD 4.1.2 Upgradeable To Lollipop?

Hello all,
Asking this for a friend who has a rooted (I believe) Fido Razr HD (XT925). It's currently running the stock 4.1.2. What is the easiest/best way to change the phone to 5.0? Unlock the bootloader, install custom recovery, and install CM? If you could also point to the best tools for the job at this time it would be great as well.
I perused the original android development sub-forum here but I could not make heads or tails out of it because some threads say not to use the tool on the "latest" 4.1.2 OTA while some say to not use it unless the phone has the 4.4 KitKat OTA update!
Thanks all in advance.

Did the first link - updated it to 4.4.2. However, after the update, the boot sequence is stuck at the Motorola Dual Core screen. Going to the recovery menu does not seem to help. How do I troubleshoot from here? Thank you.

The bootloader is not unlocked and the phone does not have a custom recovery so there is no option to clear davlik cache. Any alternative suggestions? Thank you!
No bl unlocked, can only flash original carrier ROM.
suggestion: unlock BL via motorola website, all data will get wiped

Sorry I misspoke. The bootloader is actually UNlocked. What should be the next logical step from here? Thanks!
P.S. Tried to install CWM recovery but trying to boot into recovery immediately after installing it via fastboot takes me back to fastbook with fastbook reason, "flash failure".

[Q] Error message while installing android lollipop on Nexus 5

Im trying to install Android Lollipop on my Nexus 5, but once it downloads I try to install it and it gets about halfway through the install before an error message appears and my phone restarts. My phone is unlocked and has been rooted before, but it isn't at the moment. Any help would be great, Thanks!

I am stuck in the same situation. Tried it twice with no luck.
I too rooted my phone with towelroot and unrooted it with superSu.
Did you find any solution? Please do share. Thanks.

You either have a modified system file or a file left over from being rooted. The easiest and fastest solution would be to fastboot flash the system image. You could of course flash the factory image.

Well now i remember changing the mixer_path.xml ... Will i have to unlock my bootloader to flash the factory image as i had rooted my phone with towelroot so i didnt have to do it earlier..
Also is it possible to replace the mixer path file with the original one from the internet

That sucks! ; ) I've always used the sdk so I don't know a whole lot about towelroot. Your bootloader will have to be unlocked to flash the factory image. If you can reroot you could then use the app BootUnlocker.
I just looked and I don't have the stock mixer_paths.xml anymore or I would link to it.

Thankyou for your efforts and advise. I guess i will just rerrot with towelroot, unclock the bootloader with the app you suggestee and flash factory image..
Btw. Will flashing the factory image unroot my phone and lock the bootloader or is there some procedure that needs to be done to do that?

Flashing the factory image or a system image will always unroot your device. Lock the bootloader using the sdk. The command is fastboot oem lock.
Is there a reason why OP needs locked bootloader? Just leave it unlocked, unless you have a really strong reason to. It will spare you hassles in the future.
That said, after unlocking bootloader, you can (at least, we could in the past) flash the update file through twrp (you just need to fastboot boot twrp.img and then flash the update), that will tell you exactly what file(s) doesn't match. Those are the ones you need to replace back to stock.

Thankyou.. I am more of a soft modder. Like playing with rooted apps and xposed mainly. I dont see myself flashing a custom rom. Love the stock on my nexus 5. So i dont see the need to leave the bootloader unlocked.

Do you mean restoring a TWRP backup? It won't touch your recovery or your bootloader. Just make sure you wipe properly (system, data, cache, dalvik cache) before restoring.

Don't use a toolkit, they're nothing but trouble and inevitably cause problems. It's perfectly safe to flash the cm-12.0-YNG1TAS2I3 stock images and you'll find detailed instructions in my guide thread:

I think @EddyOS's script does relock the bootloader, which you definitely don't want because once relocked sometimes it won't unlock again. He'll need to confirm that though. It definitely flashes the stock recovery but you can flash TWRP again.
