Unknown Baseband after flashing rom - Nexus 5 Q&A, Help & Troubleshooting

Last night I flashed Slim-Kat to my phone. I had a few issues and bugs one of which was no cell service, so went back to paranoid android after doing a full wipe.
I'm using paranoid android 4.45 non beta, and my baseband version in about phone is unknown. No mobile networks are seen, and adding an APN manually does not help.
I've searched around a bit and it seems my radio might need to be flashed, but I don't want to damage the phone by doing it incorrectly.
What should I do?

Wipe your cache. Should clear it up.

Two ways: track down a radio flashable via recovery (a .zip), or flash a stock radio via fastboot. The most recent stock radio .img I have on hand is radio-hammerhead-m8974a-2.0.50.2.08.img
Download the stock image here: https://developers.google.com/android/nexus/images
Extract all the files until you find the radio .img and put it into whatever folder you have your fastboot file located.
Put your phone into fastboot mode, navigate a command prompt to that folder, and use the following command to flash the radio:
Code:
fastboot flash radio radio-hammerhead-m8974a-2.0.50.2.08.img
You'll need the Android SDK for fastboot, FYI.

If you flash recovery, keep that command prompt open and be ready to re-flash your custom recovery, whether it be CWM or TWRP.

I don't, not even sure what that is.
Tried flashing the radio image from stock 4.4 factory image which is radio-hammerhead-m8974a-2.0.50.1.16 and the version my fastboot reports which was radio-hammerhead-m8974a-2.0.50.2.08.
Both have resulted in paranoid android going in a boot loop.
Going to reflash paranoid android and see what happens

Flash your custom recovery via fastboot and use it to clear caches (or, if necessary, a reset) and see if that would do it.

Fixed this by flashing the radio image from 4.4 and then reflashing paranoid android after wiping.
Thanks everybody.

Help! Trying to revert to stock rooted from CM10

I upgraded to CM10 from the original OS and I am using the latest version to root my phone, I am using TWRP. Anyway, Everything worked fine, I rooted the phone, I upgraded to CM10. I want to go back to the original OS. I downloaded [ROM][8/3] - Stock Rooted AT&T 2.20.502.7 - Android 4.0.4 - Odex or De-Odex, I got the ODEX version, I flashed it to my phone but its just hangs at the HTC One X Splash screen with the red lettering. What am I missing here? I can get back into recovery and I backed up my old ROM just in case.
How long are you letting it hang for? Try 2 more power downs and power ons. The first few times it took about 5 min to load.

It just shuts off and turns back on again, it basically loops. Did I download the wrong file maybe? Is there a specific ROM I need other than the one I mentioned earlier?

He mentioned in another thread that he did those steps. The only other thing I would try is to flash the boot.IMG from the ROM you want to use
I still want to keep my phone rooted. This wont kill the root right?
No the ROM posted above is stock rooted
But if you made a backup as you said in the first post why are you not just restoring the backup?

Basically where I am right now. I downloaded the original OS, by following instructions, I have managed to delete my backed up rom of CM10 that i backed up earlier. I was able to FLASH the OS I wanted, I flashed the boot.img file using fastboot. I restarted the phone and now its just stuck on the HTC Quietly Brilliant screen with the red lettering at the bottom. It doesn't restart or anything, it just hangs there. What am I missing here guys? ):
I'm going to install cm10 right now them go back to stock rooted and see what's up with this
There's no issues going back and forth. You probably flashed a bad ROM
yea, your most likely just doing it wrong. you need to do a full wipe and flash boot.img
answer: oh yea cant flash the stock rom using twrp 2.3.1.0 you will need to flash twrp 2.2.2.0 then flash stock rom. that is actually most likely your problem.
What hboot are you on? If you separately flashed boot.img from CM10 via fastboot, you might need to again separately flash the boot.img from the stock ROM. Also remember that the procedure employed to root 2.20 is substantially different from the root procedure to root the previous build of stock. Not sure what software you rooted, or whether this would pose a problem, but it's a consideration.
Another option is to just restore to stock via RUU and re-unlock, re-root, if nothing else works. Getting stuck on HTC splash screen sounds like a boot.img issue. Good luck.

Really? Why is that?
Just curious, I haven't heard this before. Is this a known issue with flashing the 2.20 stock ROM? I haven't seen any cases of ROMs (stock rooted or otherwise) being sensitive to version of TWRP. At least not the case of having to use an older version (keeping TWRP updated is usually the recommendation).
Of course, just because I haven't heard of it, doesn't mean it didn't happen!

im assuming the age of the stock rooted would have conflicts with the new twrp. i have had problems with roms not flashing with newest twrp. it is also a known problem since twrp 2.3.1.0 release.

[Q] Accidentally wiped system, how to revert back to stock without losing root?

So i accidentally wiped the system using twrp. But i got it to work by using a usb flash drive n flashing a custom rom from there (paranoif android) And now ive been getting random reboots and crashes. I also flashed franco kernel. Also some system apps will not work properly, such as the calendar app. And i was thinking maybe thats because i wiped the system. Now i want to revert back to stock kikat without losing my root and unlocked bootloader. Im quite new to flashing roms and i find it easy using twrp. So how do i go about reverting back to stock, to see if those random crashes and reboots will go away?

Try re-flashing another rom, as PA is a beta ROM, and thats where you may be having your crashed apps

You can always flash the factory images here: http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
You can flash any ROM and that should fix your issue
You will not lose your unlocked bootloader unless you flash the stock one which is in the factory images
Your bootloader will not relock unless you lock it yourself using fastboot. Flashing roms or factory images won't lock it by themselves.
And even if it somehow did, one fastboot command and you're unlocked again.
And as far as root goes....it takes 5 minutes to reroot.
So just flash whatever factory image you need and then custom recovery, and you're done. Maybe need to download superSU from play store after.

So i just flashed purity rom, and im still having the same issues, but the crashes and reboots are less yet their still there. Maybe reverting back to stock rom will do the trick?

The crashes and reboots are because you didn't wipe data/factory reset and also didn't wipe dalvic/cache...
If you're keen on using a custom rom follow these steps:
1. Head over to recovery and wipe data/factory reset and wipe dalvic/cache
2. Flash rom.zip and gapps.zip
3. Reboot!
Initial boot can take upto 10 minutes sometimes so be patient...
If you want to go fully stock then follow this thread:

Maybe your flashing a bad version of GApps since the force closes are on google Calander?
Are you using a 4.4.2 GApps?
Im on cataclysm now, and i believe no gapps needed since their included in the zip. Have had about 3 reboots, i believe their because of playstore downloading an update or something, and one caused by either bluetooth or hello messaging app. But who knows. Just one more thing, by me accidentally wiping the system shouldnt be the cause of my random crashes and reboots?

Why don`t you backup your user apps and data with TB and start fresh by flashing the stock image, reroot and reflash a custom rom in recovery. This will eliminate all errors and reboots.

Yes, just flash the factory image (flash-all.batt) in fastboot, reboot and setup the phone. Flash a custom recovery and flash the superSU.zip (1.94 is the latest).

[Q] Firmware Unknown

I recently wiped (sys/data/cache/dav) my opo and tried flashing the aosp .zip OnePlus released.
I completely failed to see it was an .ota and it would not flash. I restored nandroid and its a mess.
The phone boots fine to vanir/ak restore, but no lock screen, radio, etc.
Checked settings and all looks good, except "Firmware Unknown".
Should I just backup my onboard storage and use a factory image to restore?
Reflash the Vanir ROM that u restored from to see what missing elements get restored. If u have no radio though, use fastboot to flash or one of the flashable zips. You shouldn't have to completely wipe depending on which partitions are jacked, if any.

Thanks for the post. I tried flashing a Vanir nightly from Twrp and it was a real mess. It would boot to OS, but constant settings, etc. fail to launch windows popping up.
No radio on nandroid and on twrp zip flashes in any case.
Had a feeling it would take a fastboot flash of a zip.
Thinking stock cm 11s .zip fastboot flash then?

[HELP!] Not booting after stagefright update!

Hi guys, can somebody help me? I received the stagefright update this morning and after downloading it and rebooting, the phone stopped working. It shows the logo animation for a few seconds then the screen goes black. It's a rooted and unlocked phone so i don't know if thats the cause. Also, i can access the recovery mode pressing power and down. Other than that nothing.
If you were rooted and updated ya..the rooting may be the reason
So as you can access the bootloader just flash the stock rom back and you will be done with it..

But, just for curiosity: rooted phones tends to have problems after updates?
Yes It may get error or Somthing Else Thats Why I prefer if a update is avaiable flash back to stock and then proceed
Just a quick update. Flashed stock, worked fine. Thanks all.
Also, sorry for posting under general, i was so worried that i forgot to put this under HELP TROUBLESHOOTING.

Technically, it should not install at all if it's been rooted. It's interesting that Moto has let this slip by.
In the future, if you have made a single change in the system partition...root, build.prop edit....anything...even custom recovery or kernel...you should reflash your current factory image, reboot, then flash your updated factory image. It's VERY IMPORTANT you reboot between flashing one factory image and the next, though. You may have more issues if you don't.

I can not find my oem backup. I tried twrp on recovery and was able to backup other stuff. Is there a way to generate the OEM so that i can flash or any other roms that are compatible with Moto G 3rd generation?
Try wiping cache, dalvik cache and data with TWRP. Don't use stock recovery for the data wipe or you will lose all the files stored on your internal partition, as well.

XT1034 Won't boot after re-flashing stock firmware

Ok guys I'm stumped on this one. I got the OTA notification for 5.1 yesterday on my XT1034 and so I decided to preempt any issues I might have and just flash everything back to stock 5.0.2 in order to install the update.
I was able to flash everything fine then went to reboot, got the unlocked bootloader screen and...... nothing. It just stayed on the unlocked bootloader screen. I figured I did something wrong so I reset back to fastboot mode, tried again and sure enough I missed sparsechunk 3. So I tried again, restarted, and.... same thing.
OK then, reset again and reboot into recovery mode. It booted to the Motorola splash screen, ok this is different..... nope still not loading. Reset again and try flashing a custom recovery.
CWM, flashed ok, reset again, Moto splash
TWRP, flashed ok, reset, Moto splash
Philz, flashed, reset, splash
OK.. so I'm clearly doing something wrong. Did some research and tried:
- formatting the cache and userdata partitions
> cache formatted fine, userdata refused to format, not supported for filesystem type 'raw'
- tried flashing again without erasing the partitions
> flashed fine, no change in booting
- tried flashing back to 4.4.4
> flashed fine, no change in booting
- tried flashing all the custom recoveries with 4.4.4, no change
- I found a thread where someone else had a somewhat similar issue, and apparently resolved by unlocking their bootloader
> mines already unlocked, but sure it can't hurt, tried again, but nothing since it's already unlocked
I looked for anyone that had a stock 5.1 image other than the OTA, but couldn't find anything. I gave up on trying stock and looked at some custom roms, but all of them just start with, unlock your bootloader, load a custom recovery and flash the update zip file.
Soooo I'm stumped. I've tried just about everything I can think of. I made backups of everything so I'm not worried about the data I just want a working phone again. I refuse to accept that it's borked at this point since I can still get to fastboot.
OK so, no clue what changed, but I was finally able to boot into recovery, Philz
I wiped and reformatted everything and tried flashing 5.0.2 again
rebooted and it still hung on the bootloader unlocked screen
I'll try flashing Philz again and updating through there
Captains log, startdate much too late oh clock
I reflashed Philz and wiped everything again, then sidloaded CM 12.
I'm just thankful to have a working phone again so I'll go with this for now.

My experience is that you need to be unrooted, unmodified system partition and stock recovery
It's usually much easier to reflash a stock image and update than trying to unroot, uninstall, xposed tweaks, restore original build.prop settings, restore original hosts file, etc

I think at least in part what my issue was, was that the partition formatting got borked. If you can boot to a custom recovery you can wipe and reformat them. Then you should be able to reflash it normally.
I was just so tired of dealing with my phone at that point so I only tried once and gave up with stock, but I'm pretty sure that's what I need to do to fix it.
