[Q] How badly did I mess up?? - Nexus 5 Q&A, Help & Troubleshooting

I got the nexus 5 from freedompop for $140 a little bit ago. I had it sitting around for a while to gift to my sister, because I already have a nexus 5 that I've rooted (stock rom). But I got the idea that since my old nexus 5's battery isnt so great anymore, that I could transfer all my files from it to the new one by nandroid and make use of the better battery! Great idea except I didn't do any nandroid backup of the original freedompop rom or partitions in twrp for some stupid reason. I just restored all partitions (system data cache boot efs) in twrp from my old nexus 5 to the new nexus 5 without thinking.
It booted up fine but when I inserted my sim in the new n5, it said no service. I thought ok, maybe I just need to add APNs. I added the T-Mobile APN listed on their support pages, and I got a signal but it was only EDGE (at full strength). I'm getting emails and text messages so I thought it just needs further tweaking to get to LTE. Now I tried adding APNs again, resetting them, switching airplane mode on/off, switching 4g/3g/2g, turning data roaming on/off. I even tried flashing a factory 4.4.4, a factory 5.1.1 image, even M preview, and did all those steps with the APN again but I still can't get LTE signal.
After mucking about with it for a few days, I realized my mistake: I overwrote the EFS partition of the new phone with the old EFS and I have no backup of the new EFS.... Is this the reason I can't get LTE signal? Is there any way to rebuild the EFS data? Am I screwed forever without LTE?

Cant you just use Googles flash all bat file to wipe the phone over and start it from scratch? Or does that not help with efs?

Unfortunately it doesn't look that easy. I used the flash-all.sh scripts from nexus factory images for 4.4.4, 5.1.1, and even M preview, and they dont seem to do anything to the efs partition. I checked it by booting and then dialing *#06#, and all of them show IMEI as 0. I'm not 100% sure why it doesn't show my old phone's IMEI. Either way, I'm guessing T-Mobile won't allow LTE to a phone with a 0 IMEI. I dunno what to do and how to fix it

[Q] Sprint settings for Nexus S

Hi,
I have a Google Nexus S phone with Sprint. I was playing with QPST and CDMA workshop and for some reason the SMS messaging and data aren't working anymore. Phone calling does work well though.
Unfortunately, I didn't save the settings for my phone before using CDMA workshop. I called sprint but they were not able to help.
Please help! :\
I'd try full factory wipe, wipe cache, wipe dalvik. Then I'd flash whatever rom I was using before and keep my fingers crossed when I reboot that everything is fixed. Then I'd keep my fingers out of the software you were futzing around with so it doesn't happen again. I'm not trying to be a smartass, I'm saying what I'd try.

None of the things you've suggested affect the Radio (qpst/epst) settings.
Get a flashable zip of the latest OTA update, unzip it, and fastboot flash the radio.img. Either that or, if you're on the stock rom, dial *#*#72786#*#*, enter your MSL, and clear the settings (it factory resets/re-activates your phone's radio without wiping any data.)
You probably messed with the NV settings..
Flash back to stock
Go into setting and do a system update so sprint can reconfigure your setting ota

Bradart, I had the stock ROM, I dialed that number and now I can't even make/receive phone calls.
lilgrass71, yes I was testing something with NV items. I had a friend telling me his settings (but unfortunately he's on Verizon). I tried them on my phone and now I can't even connect to sprint network! it keeps searching for network and never finds anything. With this I can't even connect to sprint and update my profile or do anything! :\
Is there anything I can do to restore EVERYTHING (NV items, etc) to factory setting? the power-volume thing and privacy->restore-to-factory settings aren't working...
I'd greatly appreciate your help!
You have to go back to stock.... I mean stock stock by running the exe from Samsung

Then you can update profile one the phone is set up... But that's only of you didn't mess with any meid or pesn settings in qpst and qxdm.... That'll be illegal Tsk tsk....haha

IMEI restored, still no data

Trying to help a friend who lost his IMEI (showed as 0), I restored it with the QPST method successfully. All the numbers are there and the IMEI is correct, but it still doesn't have data. I tried calling the number in the older efs backup thread to reprovision, and it didn't seem to do anything, but while I was messing around with it the icon popped up and I had one bar of 4G, but it disappeared after a few seconds. I'm out of ideas and I would greatly appreciate any help. Thanks!

If on stock (root66 sounds) dial: *2767*3855#
Back up anything you may want on the internal storage before doing so. Should fix it if it's fixable.
This ^^^^.
I had lost mine also and followed the same instructions, got it all back, but no data return. You need to reprovision your phone by following the key sequence. I think you need to be stock to do it too (could be wrong). After doing that, all my stuff returned to 100% fully functional.
You definitely need to be on stock for it, though? What's it do specifically? I never outright lost my IMEI, but I did have a problem where data would intermittently cut out and it didn't display a phone number in the system info.
After a wipe and install it seemed to be okay, but now I'm without data. Phone number and all the other numbers are there, though. If I dialed that on CM10, what could I expect?

I already tried that, it didn't work. I just tried it again and it still didn't work, but I left it locked for a while and when I unlocked it, the 4G icon was there for a few seconds, and then went back to no signal and it hasn't come back.

Hmm if that doesn't work I'm not sure what else there is. Maybe a new SIM or phone, all I can think of
a new sim is needed, or you just have a data-bricked phone if that wont work... sorry bud
I'm not sure what it's doing, but I don't think it's unrecoverable. If I leave it for a while, when I unlock it I'll have a bit of 4G signal, then it disappears after a few seconds. I was able to use the browser while it had signal, but when I try to make a call it says "Mobile network unavailable." I did receive a few texts, I'll test sending them. Under Settings>About device>Status, all the numbers are there and everything looks normal except these:
Network - Searching for Service
Mobile network type - Unknown:0
Service state - Out of service
Mobile network state - Disconnected
Thanks for the help so far.

Have him activate another phone on his account and then reactivate the s3. I'm not sure if this will help. It's only a theory really! If you decide to try please Let me know if it works. Thanks

On mine, I restored to the Nandroid backup I made of the stock rom before switching and dialed the number mentioned before. That brought it back to out-of-the-box stock. Set it up, tested data, rooted, unlocked bootloader, installed CM10, tested data, restored apps, tested data, made another Nandroid backup, restored system apps and preferences, and everything's fine now.
My problem was really similar to that one, too. It started when the phone wasn't coming on when I pressed the home or power buttons, and after a battery pull it showed the phone number as "Unknown." A wipe and reinstall of CM10 showed all the correct numbers in the right places and seemed to fix it all, but data was back out in time. That was how it was every time I reinstalled that way; it'd work for a bit, then stop until I reinstalled again. Restoring my IMEI backup as a "just in case" hadn't helped either. Getting everything right again was arduous, but worth it.
Alright my dad has got a similar problem. He lost his IMEI before, we managed to get it restored and data working and all that good stuff. Well today he had to fly to Denver and put the phone into airplane mode, well when he came out of airplane mode it was stuck on roaming mode, and network is "Unknown" his IMEI, phone number, and all those numbers are correct but hes still stuck in roaming. We tried pulling the sim card, and going back to a root66 backup and then reprovisioning the phone. Any other ideas? Should he go back to complete 100% unrooted stock and then reprovision? Any help would be great
I've had the problem come back for me, so disregard my earlier post. I'm back on stock now with no data issues so far, so I'm going to sit on that for a bit to see if the problem is definitely with CM. It's been gradual every time I've fixed it; last time I lost LTE before 3G.

Restored a Nandroid. LTE isn't working though, so I may dial *2767*3855# to go back to full stock and see if that fixes it. Currently 3G is still okay.
A question...
Those losing their IMEI numbers... Is this happening on the locked bootloader? Unlocked bootloader? Both?
I've been digging through the forums trying to ferret out a pattern, but it's not presenting itself to me. Maybe someone else has seen the pattern?

[Q] Problems flashing an already rooted 4.4.3 over 4.4.2

I flashed the ROM and baseband per instructions in this thread: http://forum.xda-developers.com/goo...-android-4-4-3-ktu84m-rooted-busybox-t2557523
I had 4.4.2 and he said it had to be stock, and it was with the exception of potentially having some system files modified due to other apps, like Android Tuner. I wiped Dalvik cache and regular cache, installed both files as mentioned through TWRP, and yet upon starting I get a notice to update to 4.4.3 despite already being on 4.4.3, and it can't connect to T-Mobile which is my service provider. Am I doing something wrong here? I figured by "stock" ROM he meant the original and not CyanogenMod or anything like it. Was that supposed to mean stock Android with zero modifications to the system files?
I didn't want to do a factory reset and have to redo all my data and applications, but if I must then I will.
There is a rough thunderstorm going on so maybe that knocked out T-Mobile service, but I find it rather coincidental.
]UPDATE] Turns out that the storm coincidentally disabled the towers at around the exact time I updated my phone. The phone was flashed fine. T-Mobile is the problem. Thanks for the help!
It doesn't matter what ROM you're coming from but if it's not stock you need to wipe. But whatever mods you have on stock is irrelevant.
If you're having issues connecting,, wiping cache is often the cause. Check. Our imei etc is correct. Maybe fastboot flash a stock cache image or Nandroid restore

It was the original stock that shipped with the phone, with potentially some files modified from an application. Strangely when searching for networks to connect to, Sprint and AT&T show up as normal but not T-Mobile, although their APN's show up as if I am connected but can't get access to their service.
The IMEI within the phone appears to match the worn off label. Either way, I cleared the Dalvik and regular cache again so I'll see what happens when the phone finishes booting.
Surely it's booted by now?

It finished updating the apps and didn't get a connection, however when I traveled outside of my home zone to work, after I reach the spot outside of the city at which there is no LTE support and it drops to EDGE the connection picked up and remained. After I returned from work and got back in the city near my home where it switches back to LTE the connection dropped again and remained that way even after wiping the caches again.
Does this still sound like a software problem or maybe it's on T-Mobile's end?

[Q] Can't turn on Radio. No network.

Hi People.
I have a Nexus 5 that a friend gave a while ago. The phone came directly from google in Mountain View meaning this is/was a prototype phone. (It has a SKU number and a 'NOT FOR SALE' legend in the back)
The really interesting thing about this phone is that in model number it was saying "Nexus 4" even if in fact it is a nexus 5.
The phone was working perfect except for the google play that was crashing every time when I tried to open it. I factory reset the phone several times with no success. The android version it was 4.2.2 (If I remember right)
I decide to flash the phone with a newer version. I flashed everything (system, recovery and radio) with hammerhead 4.4.3.
After this update, I'm not able to connect to the network. If I try to make a call, it display: "to place a call, first turn off airplane mode".
When I go to phone info and try to "Turn on radio" it doesn't do anything.
I reflash all available modem versions with no success.
Any ideas???
Thanks.
Have you checked whether the apn settings are entered properly??
If you've flashed all the factory images then head over to the stock recovery and perform a factory reset.
If both the above things don't work, the EFS partition might have gone bad. If that's the case, then the phone is screwed.
You will need to take it to a lg centre so that they can rewrite the partition.

Easiest way to tell if your EFS is gone is look in Settings - About Phone - Status and look for an IMEI number. If its gone you need professional help to fix it as quoted above. Unless you made a back-up....

Sometimes a non-formatted or messed up cache partition can also show "0" IMEI in about-settings which can be solved by a factory reset. I hope that's the case with the OP. Otherwise he's in big trouble.

When I flash a hamerhead radio I have an imei number. If I flash a occam one I don't.
When I just got this phone it has occam. Phone model was nexus 4 (even when in fact is a nexus 5)
Now I can't flash it back to occam. Even if I disable confirmation before flashing.
Is there any way to query the modem on this device? I'm afraid because this is a prototype the modem version is different from the one it come with the rom releases.

Restored Old Phone To New; Now Can't Connect To Network?

Hey all,
I restored a backup of my old phone made in TWRP – a full backup, including Boot, System, Data, Cache & EFS – onto a new D850 I got. Both the old phone and the new one were able to connect to AT&T before this.
Now the new phone, with the restored backup from the old one, displays a network searching icon indefinitely upon reboot.
Any thoughts as to how to fix this?

Why did you restore a EFS back from your old phone to your new one? Unless you backed up the EFS from your new phone there may not be a way to fix this. EFS Is different for each phone you should never restore an EFS from a different device.

My *guess* is that I should not have overwritten the new phone's EFS with the old phone's? I think I backed up the EFS of the new phone before doing so; will restoring it fix my issue? If not, how screwed am I?

See if you have a backup of the new phones EFS try that and report back. If not it's pretty much a WiFi only device.

I restored the new phone's original EFS, and all is well.
FWIW, my reasoning behind flashing everything from the old phone to the new was that is what it said to do in every guide I read about transferring from old to new. I didn't realize EFS was supposed to be excluded; I didn't realize the EFS from one phone would be incompatible with another
In any case, crisis averted – thanks for the confirmations along the way

It's not that the EFS is not compatible. But the EFS stores info like IMEI etc. you can't have two phones with the same imei. Each EFS is different. When restoring you don't have to restore every thing though. I'm glad you had a backup! As without that it pretty much would had been an wifi only device. Your very welcome .
