Any way that you'd be willing to do the same for hhz12d? Pretty please?
[Nexus 5 Android Development] jd1639:
Don't know why you want a bootloader zip, but you could make your own pretty easily from one that is already posted. Just extract it, replace the bootloader.img with the new one, edit the updater script, and zip it back up.
[Nexus 5 Android Development] Sc4ryB3ar:
Seems to be a popular question to me today ;)

My daughter fried my computer....so I have no PC.

I'm good with the replacing of the stuffs (I'm assuming I have to find all the same files as in the existing one), but not sure if there is a particular way to zip it back up. Also, were would I find newer updater binary?
[Nexus 5 Android Development] g2uzer:
If you update to lollipop or if you update recovery (twrp) is a new efs backup needed ?
[Nexus 5 Android Development] jd1639:
Nope, efs won't change
[Nexus 5 Android Development] :
The most recent modem is still from the preview, right?
[Nexus 5 Android Development] jfim88:
Yes
[Nexus 5 Android Development] :
Actually it's not. There is a newer one included in the final lollipop build.
[Nexus 5 Android Development] phaino00:
The L preview baseband (radio) is the correct radio for the most recent releases.
[Nexus 5 Android Development] sjknight413:
No it isn't, there's a LRX21O radio pulled from the official release.
[Nexus 5 Android Development] phaino00:
This is not most recent?

M8974A-2.0.50.2.21

What is most recent?
[Nexus 5 Android Development] Holer Togni:
Yes, this is the one still included in LRX21O, so it's the latest.

Since I seem to find excessive battery drain on Lollipop OTA (google play services keeping mobile radio wakelock almost all the time!) I'm willing to try the KK radio. Will KK's radio work on lollipop?
[Nexus 5 Android Development] mo976:
I don't know if it will help your battery drain but I just flashed the KTU84Q radio with my CM12 (lollipop) ROM and everything works fine data/WiFi etc.

Yes. And work well it does.

4.4.2 Radio

I'm experiencing constant no service messages and my battery isnt the best either. I'm on offical lollipop, rooted with elementx kernel. Would you guys recommend flashing a kitkat radio? Spefically which one?

I've read the 4.4.2 radio was pretty good but i can't find a download link for it in this thread :confused:
[Nexus 5 Android Development] neopbm:
Maybe you can extract the .img from a factory image then flash it ?

But it seems it's the same as 4.4.1 : http://www.randomphantasmagoria.com/firmware/nexus-5/hammerhead/
[Nexus 5 Android Development] anwarkhan25:
That's probably why it's not in this thread. I'll just flash the 4.4.1 modem than

Ignore this post. Under TWRP 2.8.1.0 backup is created under /data/media/0/EFS_Backup/
[Nexus 5 Android Development] jcsww:
No issues here flashing with CWM also.
[Nexus 5 Android Development] nate51:
Wait, are you saying using CWM it created the restore zip on your sdcard/EFS_Backup/ ?
[Nexus 5 Android Development] jcsww:
My EFS was done with CWM along with flashing radios. I haven't done an EFS in a long time but the file in the OP is flashable with CWM and TWRP and the same for restoring it. Like stated in the OP, keep a copy off of your device because a full wipe will also wipe out the backup.
[Nexus 5 Android Development] nate51:
[MENTION=2684188]autoprime[/MENTION] ignore my first post. [MENTION=3116388]jcsww[/MENTION] I made a mistake, I read in the OP that the zip creates a restore zip in your /sdcard/EFS_Backup/ folder. I was looking on my sd storage for 5 minutes before I did a search and saw someone asking the same thing and someone said it created a restore zip on /data/media/0/EFS_Backup/. I just noticed now in the OP it does state the backup is created in the /data/media/0/EFS_Backup/ if you cannot find it on /sdcard/EFS_Backup.
[Nexus 5 Android Development] jcsww:
I'm glad you found it. I usually just use the search function in Root Explorer to find anything I don't directly know where it might be.

There's no link to that, flash this: http://downloads.codefi.re/autoprime/LG/Nexus_5/Nexus5_Flash2BackupEFS.zip

By flashing it, it's going to create a backup zip of your EFS called "Nexus5_EFS_Flashable_Restore", which you need to store safely somewhere.

5.0.2 is not a factory release for the N5 (yet); there is no 5.0.2 radio image for the N5. You'll have to use the last 5.0.1 modem.

Is there a reason the lrx210 radio was removed from the list? was it the same as lpx13d?

---------- Post added at 08:35 PM ---------- Previous post was at 08:32 PM ----------

I just tested my phone sitting in the exact same spot on my desk at work with LRX22C, LPX13D and KTU84Q and they all had the exact same db. I would say something else is causing your issue. I'm on rogers LTE in Manitoba.
[Nexus 5 Android Development] starche_old:
Well, I'll test those radio one more time. May be the reason is LTE, I'm not using it. If drains the battery way faster for really nothing
[Nexus 5 Android Development] nadrojcote:
I did not test 3g or hspa, so it may have different results.
[Nexus 5 Android Development] kafe4ever:
hi

my N5 has problems with dropping reception after changing bands (e.g. LTE to 3g, 3g to 2g). I Know, that it happens correctly for a few seconds (Base Transceiver Station transfers my signal, and i am off), but i lost my reception for maybe 10 seconds (signal bar is completely empty). After 10 seconds phone finds signal again i am back online. Maybe, my modem (i try LRX22C, LPX13D,KTU84Q) needs to increase frequency of checking my reception.

And I live in a big town with coverage 100% 3G and 50% LTE ...

edit: running stock rom all the time

any idea how to fix this issue??
[Nexus 5 Android Development] flushell:
Same here. LPX13D 2.21 has no problems and LRX22C (2.22) does. I'm in the Netherlands: Hi/KPN network but the problems are also on WiFi...

Also the reception is better with 2.21 than 2.22 like suggested here: http://xdaforums.com/showpost.php?p=57612145&postcount=1496

So I flashed back to 2.21, happy with that. :good:
[Nexus 5 Android Development] crossmission:
Bought a faulty nexus 5 a few days ago that says "no service" for 90 euros( around 110-120 dollars), I thought I might be able to fix by flashing another radio or reflash the stock image but nothing has worked, the guy who had it was running a custom ROM and because he didn't bother to wipe the internal memory I found loads of different ROM zips in there so I guess he probably somehow corrupted the EFS partition, I asked if by any chance he kept a backup but he didn't. So to my question, is there any way to restore the EFS partition or troubleshoot and check for possible other faults that might cause it?

Oh.. and merry Christmas/Happy Hanouka or whatever rocks your spiritual needs guys :)

Any idea what will happen if we flash other snapdragon 800 radios? It's made by quallcomm so maybe we can use more recent one?

Baseband version: M8974A-2.0.50.2.21

Bootloader version: HHZ12d

The only thing I know is that I need to update my baseband, because OP said my current version is LPX13D (L Preview), and the latest version is M8974A-2.0.50.2.22 (LRX22C (5.0.1)). But I don't know about bootloader version, is it already the latest version or not.

Is it ok if I only update my baseband without updating bootloader version? Since I don't know what's the latest version of bootloader, and don't know where to find flashable zip of bootloader update.

Thanks for answering it.
[Nexus 5 Android Development] AutomaticFailure27:
Yeah, that's fine. There is really no reason to update your bootloader unless there is an issue or you're like me and like new versions, but, as in the radios, newer isn't always better. They are two separate things so flashing one radio over with this bootloader or vice versa is perfectly fine

Also, latest bootloader is HHZ12D from the LRX22C image and radio 2.0.50.2.22 from same image.

should work fine on both. people are using both cwm and twrp with this. if the folder is there in recovery then the folders somewhere on your phone when you boot up.
