[Nexus 5 General] Nexive:
Just download the latest factory image for the Nexus 5. https://dl.google.com/dl/android/aosp/hammerhead-m4b30x-factory-10cfaa5c.zip

Extract the zip file and you can see the radio-xxxxxxxx.img and bootloader-xxxxxxxx.img

Copy these files into your fastboot folder

Then use the fastboot commands given in the OP but with the correct zip names.
[Nexus 5 General] Zercer:
If i want to go back to baseband .29 which one factory should i download?

I tested cm 14.1 and it sucks for now at nex5 caf
[Nexus 5 General] lo2ay:
I have bootloader hhz11k.

I guess there are newer bootloaders which exist since I haven't touched my bootloader since I've bought my N5 (2 and half years ago)

What is the newest version of the bootloader? And do I really need to flash it?
[Nexus 5 General] aldroidx:
could you please give me a flashable link to the latest version of bootloader and radio.

and does it erase internal storage?

I'm using nitrogen 7.1 rom

thanks

Hi,

Got here while looking for a solution for "no sim card found" (nexus 5, 6.0.1). I followed every step from the first post. but got stuck in the step <waiting for device> after "fastboot flash......".

I'm trying to downgrade to 5.1.1, as suggested but I cant get past the update bootloader step. any help would be much appreciated. Thanks.

Locked bootloader

it seems your boot loader is in locked condition. You required to unlock it before any flashing. search the forum for how to unlock boot loader for nexus 5 for any guidance.

Hey thanks man :thumbup:
[Nexus 5 General] nunoleite46:
If you have the original version of google, you should already have the latest version.

Advantages are that it is the version that comes with the 5.1, and is recommended.
[Nexus 5 General] asim0:
no worries, I would trust vomer as well, if the file was his...

It is also the first time I did this, but it worked for me as I was my first guinea pig (using latest twrp)

[Nexus 5 General] asim0:
Agreed! when you have a computer that is...
[Nexus 5 General] ivan.panchev:
Oh, okay. I thought it was something connected to this 'radio-restricted' update that we all applied (having its own modified radio and bootloader).
[Nexus 5 General] FuMMoD:
I agree! Fastboot is pretty fun actually when you're flashing at home. Quick and easy
[Nexus 5 General] Woody:
[MENTION=1632145]FuMMoD[/MENTION] Vomer's BL/Modem.zip is ok man. I flashed Cata without it (worked fine as we suspected), then a few hours later, flashed Vomer's zip (again, worked as advertised). You should be good.

One word of caution: Check the md5 cause DH is ridiculously slow and there is always a risk of corruption when it is that slow. BLs are not something to be trifled with. Modems can always be reflashed, but BLs are the one sure way to brick. As in carpentry, measure twice: cut once.

******************
[MENTION=563966]nunoleite46[/MENTION] Certainly not trying to hijack your thread, as I feel if more people knew how to fastboot on PC, we could reduce soo many of these silly "How do I flash the newest X files?" posts. I was just helping and Guinea Pigging for a few who don't have access to a PC for one reason or another.
[Nexus 5 General] igordevezas:
hey mates,

whats the diference from update this way to OTA links?

Thanks!!

This is for costum Roms not necessary if you get OTA

Nexus 5 ? by Cataclysm + EX
[Nexus 5 General] Eogram:
Well, that didn't go well for me. Hoping somebody can help.

I followed the instructions in the OP. Both files flashed without issue.

Then I did 'fastboot reboot'... and my phone turned off.

And won't turn back on, no matter what I do.

Battery was at about 85% before I did this. I've held power down for a good minute or so to try to force it to turn off/on, same with any combo of power+volup+voldown.

Nexus Root Manager doesn't detect it as a connected device.

Not sure what else to try, any ideas?
[Nexus 5 General] farsight73:
wow.. I was just about to flash my BL & radio using PC.. you're killing my mood now..

[Nexus 5 General] Pete182:
Sorry for the newb question but after updating the bootloader/radio I just need to do a factory reset and I can then install a 5.1 custom rom? Or should I do a full wipe?

[Nexus 5 General] nunoleite46:
First time I heard such a thing. the phone charges? I have no idea of what might be.
[Nexus 5 General] nunoleite46:
Yes, you just need to do a factory reset (wipe data, cache, dalvik) and then install 5.1 costum.
[Nexus 5 General] ek69:
Might as well wipe system too at the same time to be safe :)

Hello!

Sorry for my n00b question, but what's the point of this thread? You can simply extract whatever factory image you want and flash it all or just any individual img inside.

Regards, Zagor
[Nexus 5 General] procitysam:
It's so that if you don't want/need the factory image, you can just download this and be on your way.

[Nexus 5 General] Avensac:
Is there a way to check which version of Bootloader and Radio is on device? And what brings updating to the new bootloader and radio? Is it a must, and for what?
[Nexus 5 General] ameyk85:
To check bootloader, reboot to bootloader and check the version. Radio version can simply be checked by going to the Settings -> About Phone section

Its not mandatory, but recommended to update the bootloader when installing 5.1 ROM as the official OTA update from Google updates these things automatically
[Nexus 5 General] ameyk85:
Thanks, was able to update the bootloader successfully by updating the PC drivers. :good:

Im lazy and just copied the whole command with filenames in tutorial and it worked perfect. It just you cant ctrl+v as paste, you can either paste with right click on mouse or I think it was something like ctrl+shift+v or ctrl+alt+v. There you go, happy flashing.
[Nexus 5 General] Adrianrff:
Hi, I have a few doubts.

I'm on Chroma 5.1, coming from CM 12.1, coming from stock 5.1 (installed via official OTA). Do I need to flash the official radio and bootloader images or does the fact that I'm coming from 5.1 stock updated via official OTA and haven't flashed any radio or bootloader images (knowingly, at least) guarantees that I already have those? In case I need to flash them, does it make any difference if I just put the images in the internal storage and flash through recovery? Finally, how can I be sure, i.e., how do I check which bootloader and radia I have on my device (Nexus 5)

Thanks in advance
[Nexus 5 General] Bas Schilperoord:
It could very well be that Google has included the Radio and Bootloader update in its official OTA images. You can check the version number of Radio and Bootloader by powering on your device, holding the power and VOL - button.

[Nexus 5 General] pringled:
I just got my Nexus 5 yesterday and couldn't install PAC or Xenon because they required me to update my bootloader to HHZ12F, so I upgraded it to HHZ12H thinking that'd suffice but they still said I needed F. Also, to anyone one using MultiROM who winds up in my situation, to downgrade to F through recovery you've got to flash the bootloader/radio zip through multirom as though it were a ROM and then inject it. If you do it normally it won't take, even if you inject it from the main screen.

[Nexus 5 General] seilogeo:
I have flashed the new bootloader and radio.

I have multiboot. Primary is Euphoria 5.1.1, secondary Cataclysm 24.10, both work perfectly.

Same signal to both roms, no problem on 5.1.1. Flash with no fear!!

Also before I flash it, cataclysm was also working without a problem with the previous lollipop radio.
[Nexus 5 General] bikerabhinav:
Pardon my ignorance but why is this a separate step? I thought flashing a M stock image would update bootloader and radio as well because it did in my case.
[Nexus 5 General] seilogeo:
Because not everyone flashes the stock image, especially if someone uses multiboot like me for example.
[Nexus 5 General] luke9631:
So if I want to flash a custom rom, lets's say the 6.0 cataclysm version, should I first follow this procedure?
[Nexus 5 General] seilogeo:
If you have flashed the stock image you are already updated to the the latest radio-bootloader no need to flash anything else.

In contrary if you havent flashed the stock image, you need to flash the latest radio-bootloader manually, in order to be updated and use a 6.0 rom without issues.

fastboot flash success

I flashed successfully via fastboot from PG.1 instructions.

And then installed the latest CM13 Nightly. It downgraded my BL and radio back to h and .26.

So I guess I'll have to wait until CM changes them

To make it easier to locate fastboot folder with CMD.exe

I just copy cmd.exe into extracted fastboot folder and execute from there

Renamed Bootloader to BL.img and Radio to R.img for the flashing process

Kept a copy of the zip with original file names to archive
