[Q] GT-i9250 Baseband unknown & IMEI blank - Samsung Galaxy Nexus

I did an OTA upgrade from ICE Stock 4.0.4 to stock JB 4.1.1.
After a day there was no mobile network available, though WIFI work. I tried other SIM but no network.
I see that IMEI, baseband etc. is coming as "unknown"
As all my efforts of factory reset, reboot etc failed, reflashing the latest images and going back to 4.0.4. etc.
But still no network.
In the phone settings
Basebad version : unknown
Network : Unknown
IEMI : unknown
Service state : Out of service/Radio off (keeps changing every 4-5 sec)
No idea what is happening.
I saw similar issues reported but not able to figure out how finally they solved it.
I dont have backup of efs folder as well
I tried with couple of Samsung Service Centres in Bangalore, India but they are not accepting the request as the phone was bought in US and also that Google/Samsung is not selling i9250 in India.
Any suggestions/help is appreciated.
Thanks in Advance

HELP
Also having the same issue. Been researching and still haven't came up with a solution. Thread bump.

Bummmmp
I got same issue, I unlocked a Canadian rogers i9250 with the DOCOMO unlock and haven't had original IMEI since, however when I plug it into ADB I see the original and I still see it on my box. I'd kinda like to fix it too, not sure what the pros or cons are.

Did you guys tried to fully wipe and go back to stock image? When I say full wipe it means using adb and applying a full reset. Try the toolkit on the dev forums if adb is not your cup of tea.

How do you "fully wipe with ADB"?
OP, check 'mount' output. Do you see /efs mounted at mount point /factory once fully booted?

When I say fully wipe is not using the recovery, but using the command terminal to flash the full Google factory image

Unfortunately full wipes and stock restoration does NOT recover your IMEI, there are tons of threads about this, still no simple solution however.

OK, thanks very much for these information. Oh well, seems like I have to buy another mainboard

Just a second! Your phone isn't exactly 'dead', have you gone to the sim toolkit to recognize said sim card or is this a Verizon model? Sorry using tapatalk so having to flip back and forth lol I would suggest trying another sim to make sure you're 100% unlocked.

Also double check APN settings as I'm sure you have heard of this multiple times. Also if you're comfortable with flashing, go for CyanogenMod maybe it will fix what you need as its the number 1 updated custom ROM. Its packed with a kernel that's updated as much as its ROM. Try wiping entire system and flashing via adb side load provided you know what I'm talking about and have a recovery that supports this ( I use TWRP)

Your phone may ultimately end up like my own, my imei and network still say unknown but my carrier is wind and I'm using the 3g to answer you right now in assurance it works regardless of imei

I just realized you could try re unlocking it, Google DoCoMo galaxy nexus unlock!
Edit : because your imei is already blank you shouldn't really need to worry about what it backs up.

Thank you for you reply. I'm not familiar with flash. But I can do following the guider……
Some days ago, I received an OTA update, I tried to install it. however, it failed. because I deleted some Google's apps. So I tried to update my NEXUS using factory image from Google over cable. It was successful. But two days later, I found my phone lost signal. And then I found baseband version unknown, and IMEI too. I did nothing with it except connecting to PC overnight. I tried to find out why and how to fix it. Someone said efs was corrupted. But I didn't backup it. Even I didn't know which folder was efs. factory? or in dev/
block/platform.....? or same? Now there are several files in factory, but no one file in data/radio as you shown in your reply. Now I don't know what to do..I dont want to use my Nexus as a player...

Sounds like my old problem actually heh, well unfortunately it seems you won't be able to recover your original IMEI because it at some point was rooted and unlocked with DoCoMo method (Like myself, you won't recover IMEI but connections will work!) What I suggest you do is download the Galaxy Nexus Toolkit by Wugfresh and flash stock 4.3 factory image. Then go from there. (Best for you because it will restore STOCK radio)
The reason your OTA didn't work is because the Google apps you have removed are linked to gapps (where the ROM went to update them but there is nothing to update) also because you're device was/is? Rooted.
I suggest the Wugfresh toolkit because it's especially useful for beginners.
I'll find the link shortly, just at work right now.
As for your English, I'm a Canadian and I can tell very clearly what it is your typing.
EDIT - here you go good sir and hopefully we can breathe life back into your amazing phone! http://forum.xda-developers.com/showthread.php?t=2208863
Those logs almost look as if a wrong radio was flashed, I could be wrong though if you haven't flashed before.
Let me know if there's anything else you need.

My S3 says "upgrading" all the time

After updating the phone with an ATT update, every time I restart or boot up my device it says that "Android is upgrading". Does anyone have the same issue? How do I get rid of that?

I suspect that the update didn't go quite right. It says that when the system is rebuilding your cache/dalvik cache. It sounds like maybe one or both of those is getting cleared when you shut down or they may not be getting built properly in the first place. I'd suggest backing up whatever you care about and doing a factory wipe. It can be a bit of a pain, but it'll probably solve your problem.
Also, bring on the details yo. Phone? Android version you came from/upgraded to? Aaaaaanything at all.
I has Android 4.0.4 and the latest update. It's a rooted phone and AT&T is my provider.

Are you running a custom ROM? I agree, you should do a factory reset. Just be sure to back up your data beforehand.

No, I am not running a custom rom, all I have done to the phone is root it. What's the best way to back up your data? I useTitanium backup. How do I do a factory reset? I am new to the Android world and don't know much, any help will be greatly appreciated.

What phone do you have? Titanium backups are fine. Make sure the backups are on an external SD card or get them off the internal flash. If you need to shuffle files around, you can use ES File Explorer but BE CAREFUL if you give it root privs for some reason. No offense, but since you're kinda new to this if you screw up and erase the wrong thing, stuff's gonna break. Without knowing who makes your phone, the best I can tell you is to go into settings and dig around for the factory reset. Good luck!
I fixed the first problem with the factory reset but now I can't connect the phone to my Mac using Android file transfer. Could the update had something to do with it?

Like the other guy said, the update could be a possibility.
Reminds me when I had iPhones before I discovered Android. If you wanted to stay jailbroken, you'd have to make sure it's safe to do so before you update. Like you had to make sure it was iTunes safe, etc.
Did you install Google wallet?
Sent from my SAMSUNG-SGH-I747 using xda premium
So if AT&T has an update and your phone is rooted, don't update? I went ahead and updated without thinking about it. I am an iPhone user and didn't think that ATT had anything to do with Android OS. I took care of the upgrading issue, before the update I was able to use Android File Transfer with my Mac and I would connect to the phone, now forget about it. I can only do it now using VMware Fusion. Kies works but it's kind of limited. My next thing will be to install a ROM, but I can't find exactly what kind of phone I have. I know it's a Galaxy S3 from AT&T.

What kind of specific rom's I have to look for, I've herd that if you install the incorrect rom you will brick your phone.
Im not very familiar with mac or iOS but your problem sounds like a driver issue on the mac, not android. Is usb debugging enabled by chance? Settings>developer options>android debugging....if its on try turning off then reconnect your phone. If its off try turning it on and reconnect and see if it changes. Beyond that i would suggest deleting any samsung/android usb device druvers from the mac and reinstalling....although someone with more iOS experience will have to offer some advice in exactly how to do that if you dont know, i certainly dont.
As far as installing AT&T OTA updates with root, its generally not a good idea, especially if you do install a custom ROM. Even on a stock rooted ROM there is a pretty good chance the update will 'fix' your root access and if you are on a custom ROM there is probably an even better chance of screwing up the operating system to the point that it doesn't boot properly, or even brick. Only install updates to your ROM from the developer, and follow any instructions they give on how to apply the update.
Lastly, you are looking for AT&T i747 roms and you also have to pay attention to which version of android you are on as to how you go about installing the ROM. For instance if you are running the stock AT&T ROM and try to install an AOSP based rom without formatting the device you are more than likely to have all kinds of issues, IF the OS even boots properly. I would suggest you take some time to read up and become familiar with the terminology, differences in versions, etc with android before you just dive in. If you are unsure about something ASK SOMEONE...much better to look like a noob than standing in line at AT&T with a bricked phone.
I was under the impression that all of these show that when rebooting, its just a matter of how long it shows this message. I dont think anyone with a stock rom does NOT see this when they boot for a couple of seconds.
Any good place to begin looking for stock ROMS?

Now major problem 2 is that I was trying to install a rom using twrp I accidentally but it wit no OS loaded and now it can't be recognized by the computer. How to I get to load the OS back?

Do you still have twrp recovery? Not sure about you twrp part you said you accidentally did something. You will get that no OS message after you perpormed full wipe then reboot device without flashing a rom. Download a custom rom and save to external card then flash using twrp recovery if you can still access it.

Then downgraded to 4.1.1 and went through the secret menu method to unlock but it still will not allow calls and still shows the stop sign @ the top right on the signal bars then it disappears. The apn settings are being recognized as t-mobile and everything as far as I can tell is ok but it can't call, says only emergency...any help here?

[Q] Tmo T999 No 4G

Hello,
Obviously from my posts I'm new posting, however, I've been reading the forums for a while now and have been a huge fan at the massive support of devs and other helpful people. My question, and I've tried searching hi and lo on this site and others to get an answer:
I rooted my phone about 2 months ago and kept ROM, kernel, etc. stock until about 1 month ago when I flashed CM 10.1. Everything was awesome, loved the layout and the customization of the ROM. About 2 weeks ago, I lost 4G/H+ coverage, and voice service was sometimes spottier than usual. Wifi was and is still fine, but anytime I left and wifi network, I was immediately given EDGE speeds. I ran speedtest.net and the display is accurate.
I tried searching a couple of sites and I read that flashing a different ROM could fix the issue. I flashed Wicked which again was a great layout, but didn't fix the 4G issue. Lastly, today I followed an unroot thread and unrooted my phone. I didn't reset my counter with triangle away because I didn't think that was an issue in the lack of 4G. And I didn't want to dig myself any deeper on possibly bricking my phone. So now, my phone is stock (minus the counter) with ROM, kernel, and recovery. Any tips or suggestions?
Something to note: When I tried flashing CM10.1 the very first time, I received an error 7 message on CWM recovery. After reading a couple of posts on here, it looked like the workaround was to remove the first line of code on the updater-script file in the zip. Doing so made the ROM flash without any hiccups. Or were there?
Again thanks in advance for taking the time to read my post.

Its not really bad, but its not great. It means you lost your imei, it just happens randomly when flashing a ROM (no one knows why, it just rarely happens). Its not the ROMs fault, it just happens.
If you haven't made a backup of your imei, then you'll have to restore/inject the imei so that you can use 4g again. I'll have to look for the threads that explain how to do that and I'll post them for you.

I wouldn't worry bout it. Unless you get lucky it can take a lot of searching and piecing info together to find all that's needed. Imei restoration can still be found, but a lot isn't too clear. Data restore after imei restoration is not so easy.
Also, one or two of the important threads are gone. If you ever need help with this issue, you can just pm me.

And thank you too Doc! I'll post my results in case anyone else has this problem. I'm certain this will work. Thanks for the future reach-out invite as well.
Hey Doc, does everything in the video I posted restore 4g or does it just restore the imei? If it doesn't restore 4g, could you please post here or pm what steps are needed to get 4g going again?
I would just like to have a copy of everything just in case something goes wrong with my imei backup, If I end up losing my imei.
Edit: Hey keeeoh I removed the video (thank you Doc for the heads up). If you need the link to it, just let me know and I'll pm it to you. Once again, thank you Doc for letting me know.

Well, Success!!! Needed to do a couple more things but both of you were able to get me back up and running on 4G.
Dakine - Already got the video, so thank you anyways.
Doc - Finished those steps, for some reason I can't PM you so if you can PM me again to let me know what I need to do avoid this in the future, as I'd love to go back to a rooted phone.
Thanks again guys!

Awesome! Glad you got it working again.
Next thing is to create s n on-device backup of your nv data. This should only need to be done once, as you can't delete or overwrite it with common methods. It is also preventative so you shouldn't ever see this issue again.
Two methods
1. Install Andromizer and backup nv data
2. Install and open Terminal Emulator and enter this:
su
reboot nvbackup
That's it. Your phone will reboot and create the back up. If you do ever need to restore just enter this:
su
reboot nvrestore
Note: you cannot make copies of this as its stored across several partitions that are not easily accessible.

What were the "couple more things"? My IMEI was wiped when I installed CWM and I had no signal showing at all. I have restored my IMEI and it now connects to Edge but it does not connect to 4G as it did. My wife's phone still gets a good 4G connection so I think it is the phone. I have tried wiping it, installing Cyanogen and have now reverted to Samsung factory UVDMD5. Everything about the phone seems to work great except it has no 4G. Tried changing APN type and forcing WCDMA -- no luck
Thanks!

Low 2g and 3g but no 4g
I also can never get 4G in the metro. Even right next to somebody with the exact same phone and same T-mobile service who gets it fine.. I had flashed Synergy ROM and now S3Rx (stock kernel) but no improvement. My IMEI is valid, the Mobile Network type is shown as: GPRS:1. It shows the APN as T-Mobile USA (epc.tmobile.com). Baseband version is: T999UVDMD5.
I don't know anything else to check. Sure would like some ideas.
Test with someone else's SIM card. Or call T-Mobile as it sounds like it may be an account issue. Odin back to stock. If it still continues, it could also be hardware.

Hello Doc, I tried to pm you, but never received a reply, maybe my message is blocked.
I hope you can help me find cure for my phone!
After regular update of CM 10.2. using CWM my phone stopped connecting to 3g and 4g, I checked with T-Mobile and no problems on their end. I thought it was a failed upgrade reinstalled CM 10.2, didn't help. Then I totally reformatted Internal Storage and Installed LiquidSmooth 2.3.7, same thing, only EDGE data. Then I thought maybe I have to unroot and go back to Stock, and this time unrooted, upgraded baseband to the latest version, then installed Stock JB 4.3 but it didn't fix my problem. Then I came across this info about missing IMEIs, and there it was IMEI was showing Unknown at one point and now it is showing 0. I tried to follow some guides about nv_data.bin but my EFS folder doesn't seem to contain that file, it actually doesn't have more than that when compared to other user's screenshots.
At this point I rooted my phone again using TWRP with SU and De-knox and installed CM 10.2.0. Still EDGE only and IMEI showing 0.
Please, help! I can email screenshot of About Phone Status Page and EFS folder if you need.
Thanks!

Doc,
I just purchased a T999 on eBay with this same problem. When I got the phone, it had CM installed on it and had no IMEI (IMEI=0). I put it back to stock 4.1.2, still no IMEI. I did IMEI repair using Z3X box which worked, now IMEI is normal. Problem is that it always stays on EDGE network. I'm sure this is something to to with the phone and not something else. I have a couple of other T999's available to use to test SIM card, location, etc. and all other T999's I've tried work just fine. Only this one that I had to restore IMEI.
Can you please give me some advice?

Bricked?

So I found my old s2 and when I turned it on it always boots to safe mode where nothing comes up only screen with status bar and absolutely nothing else. Volume up works only when holding power button and volume down isn't working at all even in recovery so I am unable to get it into download mode or navigate recovery to try factory reset. Is it a lost cause? Or any ideas to fix?

Nope, your phone is fine. Your volume button is stuck, which makes you boot into safe mode.
Open up your phone (if comfortable) and gently wipe the switch for any debris present.
Will try. Thanks

I was kinda weary on taking apart since its still insured but it was a lot simpler than I had anticipated and wiped it down with alcohol pad and sure enough it worked like a charm. I was then faced with android.acore crashing but since I can now navigate recovery just did hard reset and back to normal. Any advice on best ROM and kernel combo and best way to flash? Thanks again

Personally, I like the Hellybean 4.2.2 ROM. It has excellent performance, overclocked GPU, init.d support, overclocking/volting support, and a sick dark theme. (Don't go with the 4.3 Hellybean, it has memory leaks). I'm pretty sure there is a Hellybean 4.4 in beta at the moment, you can check that out if you wish.

For CM10 and abovre, the minimum version radio firmware that you need is UVMC6. If you do not have that installed already, baseband will show up as unknown. Your SIM card is probably not being recognized because of this.
Search for the UVMC6 zip and flash it FIRST in your recovery (CWM,TWRP), before you install any ROM.

Well then, install CWM or TWRP via ODIN, then install the UVMC6 radio zip.
Most likely, your current radio firmware is corrupted.
my issue with this is as follows. i can only odin into stock ICS any other attempt to odin jb or flash custom ROM on it results in constant rebooting during "android is upgrading" upon first boot... wipes have not alleviated this issue. on stock ICS i get a circle with a slash through it no baseband or imei. have flashed multiple radios and they dont seem to stick at all. the one thing i havent tried is flashing an ICS rom like cm9 or such and flashing the radio to see if itll stick that way. so i guess my question is is there a way to fix this issue or could the radio be fried?
Try using Odin 3.0.4. Only version I had luck with flashing stock jelly bean. Before you Odin tho....use the 2 infamous wipes. Cache one and superwipe one. Found in dev section.
Give that a go.

That is where things like the IMEI and MAC address, etc, are stored.
Boot to recovery;
mount /efs;
Open a terminal:

# cd /efs
# ls -a >> /sdcard/efscontents.txt
# exit
adb pull /sdcard/efscontents.txt
Paste the file here so I can compare it to my /efs.

Did you flash the latest TWRP (I believe 2.6.3.1) via Odin or Heimdall? If not, do that first.
Unless your USB port is broken on the phone, it should work and get recognized.
Have you used adb before on your phone?

If it is dying, and the screen and other components are in working condition, you could sell it on eBay for around $85-90.
The SGH-I727 (Galaxy S2 Skyrocket) has similar specs to the T989, and you can find those being sold on eBay for around $100 to $150. I am not sure exactly why it costs lesser than the T989, but it is (and I bought one for my dad for $133 USD). Both have the same specs, same processor, GPU, storage, etc.

baseband error [CHINA]

That's my first post on xda, I'm sorry for my English.
The problem is that i changed the GSM band to USA BAND in *#*#4636#*#*, then it cannot match chinese GSM band. Before I did this change, GSM has worked well and phone or SMS could work. Someone said that the same problem has been reported on Moto X, but esay to solve: erase modemst in fastboot. Or the same problem on Sony Xperia series, it needs flash radio.img.
NOW I HAVE TRIED THEM ALL, but still cannot work.
unlock and reset to factory data
double wipe in recovery
fastboot erase modemst1 ------failed, failure information is "REMOTE: not support to erase this partition"
flash factory image, both MDB08I and MDA89F
flash radio file
so...I think that i need the baseband file to flash, but such a new phone how can i find it?
OR maybe caused by same reason that TWRP cannot work before FORMAT but not wipe to unlock the secure partition?
------------------------------------------------------------
UPDATE: QUESTION SOLVED
Thanks a lot to developers. bidomo gave a effective method on #10, and #31 may be helpful too.
At last, i tried to erase modemst1 and finally solved this problem, but it's so hard, it must through ADB to open the Linux file system immediately, find the modemst1 folder's location and delete it.
I did the same thing with my 5x a few days ago. I am so fed up looking for solutions that apparently do not exist. I have factory reset the phone. Flashed a few roms, flashed 3 different stock firmware versions and investigated a few toolkits to see if there are any interesting options that might help me out. Nothing.
Im in Croatia though. I bought the phone from Amazon.de and its a Dutch model. Everything was working great before I had a brain fart and changed the setting.
Im getting quite despondent about this.
Would love some input for me and the guy above.

So what exactly is the problem you are having with your phone?
Mark.
Firstly, thank you for the prompt reply to this issue.
As the first poster did, I changed my radio band to USA and have no applicable settings on my phone which will allow me to change back to my European band. So, as a result I am unable to use my phone. It reads, no service. To be exhaustive, I have obviously turned phone on and off, aeroplane mode, changed to a different sim card, factory reset, flashed radio.img files on top of stock rom, flashed all the firmwares available for this device over fastboot, flashed pure nexus rom to see if it might have an automatic or global mode for providers like i recall CM roms having a few years ago. All to no avail. So now I am standing in front of my laptop with my reflashed stock 5x, downloading my apps over a spotty 3g broadband connection, hoping that someone such as yourself will have a file, zip, or answer for me.

First thing to try is an app called Nexus 5 field test mode. Im not sure if it will let you do anything for the 5X but its worth a shot. You need to be rooted to use this app so you may want to do that first.
Mark.
Thanks for the reply. I will get to it later on today when I get some time. However obsessed Im being over this issue, I cant ignore my 2 year old like I did yesterday. I just wished to ask what would be the second, third thing I might do if this app does not work or help. Just so I can crack on with something else asap.
Again, I appreciate the help.
Marko
'This app is only for nexus 5'. The play store showed incompatibility but I went and downloaded an .apk anyway. Nothing. What next?
Thank you again for any interest in helping me rescue my phone. Like I said before, I can't just "take it back to the store" or anything like that.
Marko
Having read and read and read some more, it seems that the course of action is 'simply' to flash a new or rather original QCN file using QPST software. However....I need a European Nexus 5x QCN file and...well, knowledge on how to use the tool.
Marko
maybe somebody whith knowledge can find out the solution from the source code https://android.googlesource.com/pl....0_r26/src/com/android/settings/BandMode.java

Before both of you start editing and/or wiping your efs to cause more issues
I made a custom rom for nexus 5x which instead of querying the baseband for available band modes just displays all six band modes. I could not test it on a nexus 5x as I dont have the device, but for my nexus 5 it does work
When I set usa band I lose my signal, but when I select automatic band selection or euro band I get back my signal.

Wow. First of all, let me start of by saying THANK YOU VERY MUCH for showing an interest. Im going to download now and give it a try for sure. Im sorry that I did not reply to your prior post, I was just not in a sort my phone out mood in the last few days as I was more concerned with my daughters first few days of nursery.
I stated in another thread that I made a couple of days ago that I was going to send my phone back for a replacement which I did not think I would be able to do. But I still would rather see if your rom works to set back my bandmode instead. Rather than waiting weeks and keeping my fingers crossed so that a truly faulty unit does not make its way into my hands, if at all.
Again, even if this doesnt work, I really appreciate the help, not only as per your second post, but simply for your reply in the first instance.

I think I failed about extracting the proprietary files for nexus 6p from the system image. Sadly google still havent release the proprietary binaries for nexus 6p.
I will try to build a rom based on purenexus rom but I left home and will not come back until weekend. So you have to wait or build your own android by commenting out
if (size > 0) {
for (int i=1; i<size; i++) {item = new BandListItem(bands);
mBandListAdapter.add(item);
if (DBG) log("Add " + item.toString());​
}
addBandSuccess = true;​
}
