[Q] baseband, imei, imsi, phone number all unknown. no signal...

Hi there
Ok starting from the start.
My phone is not rooted (it is still s-on).
The phone was bought on ebay a couple months ago.
It has been working fine.
Yesterday, when pressing the power button to unlock, the lights came on but the screen did not.
This happened a number of times after rebooting the phone, then eventually it randomly came on again.
However, the signal, never came back. The phone thinks it's in 'airplane mode' when I press call. There is no airplane icon up top. I have turned airplane mode on and off each way, rebooted, hard reset and cleared all the data from sd card and phone. Wifi works, but signal is still 0.
Still same problem.
When pressing further, I noticed in the 'About' section of the phone, that the BASEBAND is UNKNOWN! So is the imei number etc.
I did a few google searches and couldn't find much; although it was suggested that I reflash the stock rom. I am unsure how to do this.
Please could somebody point me in the right direction, because I am panicing here.
Thanks very much

You can use the European version in Canada as well just fine if you happen to be here.
I flashed it to upgrade my radio version to get rid of GPS issues while using Jikantaru's XE ROM and it worked.
Ended up using the Euro version as my main ROM until 7.2 of Cyanogen from Alquez came out.
Still have an issue with the wifi in that so I, at Alquez's suggestion, use the libril.so from that Euro stock rom in Cm7.2 and it works much better.
The Euro stock release was solid in all regards, strong wifi, GPS, phone signal, etc.
Just follow the instructions on how to flash a stock rom.

Thanks guys. Will let you know how it goes.
I just turned the phone on without a sim card and it all came back (nothing was 'unknown'. Does this mean that the sim has something to do with it!?

Radio issues with 4.2 Roms

Hi all, I am again posting about having radio issues. (NO T-Mobile signal) Any 4.2 Rom I try to install, I am unable to obtain phone service. (signal)
Here is what I did:
1. Start from scratch, total erased phone and sd card and micro card.
2. Odin flash stock Rom and Odin flash latest TWRP
3. Copy Rom to SD card and flash. (flash is fine)
4. No signal, flashed newest UVM6 radio, all kind of wipes.
My phone is SGH-T989 T-Mobile. I even changed the APN, but still only pick up AT&T which still having no signal bars. I tried flashing all radios available with no help at all. I am able to use certain 4.1.2 Roms such as Infamous 3. I even tried different kernels, different wipes and just can not get any T-Mobile signal service. I have tried searching for any and all radio issues for this phone. NOTHING works for me. Can anyone or does anyone have same problem that came up with a solution to get a signal for T-Mobile for these Roms? I am currently using the Infamous 3 Rom using Arc kernel. Actually the only other Rom I can use it the stock deodexed rooted base. Very frustrated not being able to use these great looking Roms, HELP please! Thanks for any information or solution. BTW, I have tried everthing and every type of wipe to no avail.

do you still have your IMEI or does it shows blank and unknown ??

I am having the same issue. It does show my imei # though. How do I fix this?

Oh boy.....again.
K....here is about everything. If none of this is your problem, since you say you've checked everything....and yes, I have read your other thread....in which you repeatedly say you tried everything, then you have a hardware issue, or are simply doing something wrong and telling us you did it right.
Not getting a signal.....
- not using latest T-Mobile or Telus radio. Maybe you flashed it, but is it actually showing as that radio in settings??
- APN settings are wrong or don't exist. Lets pause here. You said you checked apn and only pick up at&t. Or am I misreading that. If you don't have the correct T-Mobile apn settings, then you wont get a signal or data. Period. This has to be correct before bothering with anything else. You said you checked. Against what?? I've seen plenty of apn settings when Googling it, some simply don't work. Maybe they are old settings, wrong phone, whatever. I'm Telus, so can't help you with the settings for T-Mobile.
- what has already been posted above needs to be correct.
- maybe radio file you flashed was wrong one or corrupt. Perhaps try the Telus one. Should work too. Since T-Mobile radio works on Telus.
- restoring any system data after a flash? Huge no no.
- wrong mobile band selected?
- and a possibility .....simply no signal where you are. Or it's a weak signal, and your assuming it doesn't work?? Ignore this if you have a very strong signal usually where you live. 4.1.2 to 4.2.2 shouldn't affect signal much if any.
Anyway.....that's about all there is to it if you are CLEAN flashing roms and following instructions to the letter. I am confident you will say all the above is good....and if so....I am afraid you will probably find no answers like your other thread. Meaning you have an extremely rare issue. Or a wierd hardware issue, sim card maybe....tho before you dismissed that as a cause. Another possibility is that you aren't correct when you say apn is fine, or the radio you flashed is fine. Not accusing you of misleading anyone, just saying perhaps you are innocently wrong when you tell us this or that is fine when it is not.. I've done tech support.....happens all the time! !!
So, good luck. Hope you find a solution ......tho this is your second thread on same issue....so you may have some rare issue....and may be boned.

I have been dealing with this problem for weeks, and I can almost guarantee you don't have the radio right and that's the problem. http://forum.xda-developers.com/showthread.php?t=2385987.
Here is the link to a radio I just flashed literally 5 minutes ago and started running 4.2 roms after weeks of struggle and frustration.

That would certainly make sense!
He's got something wrong for sure. Or he's got a strange phone that won't work with 4.2. And I doubt that very much.
He's got wrong radio, or wrong or missing APN settings.
Or wrong phone, sim or carrier.

Thanks for helping and I think your right about being boned or hardware issue. I have tried different downloads of radios, both Telius and Tmobile and copied APN settings from working stock Rom. Maybe bad Sim, anyway I will have to stay with what I have until I get new phone, which is soon. Thanks again!

Stumbled across this. I've never heard of this particular issue before, but sure sounds the same as your issue. Try this fix if you haven't already.
Everything below is copied from another thread......
i had this problem with slim too. i thought something went wrong with my phone or my area. but nope. what you need to do is go to mikeyman777 cm10.1 thread and find the uvmc6 tar file, then use odin to flash it. apparently just flashing the newest radio with twrp isn't enough because it's missing some files or something like that lol.
anyways i haven't had signal problems since flashing radio tar file. i've lost signal like once. before i was losing it everyday. hope this helps.

And finally you have paranoidandroid or back again in the previous rom? With a little search in the forum i found this "Hey...I found out why I didn't have service and was able to fix it. When I had flashed AOKP, there is a setting in the Mobile Networks screen to change the CDMA subscription to RUIM/SIM. Somehow (probably playing around) I changed it from the NV to RUIM/SIM. THEN, I nandroided back to stock, and had no service. As far as I know, that CDMA Subscription option isn't on the STOCK ROM...so I was baffled. Good thing I remembered what I did."
Try it and report..!

i'd recommend that you flashed again your previous rom to see if it is rom related or not. I ve read somewhere that some people had problems with the signal when flashing aokp.

i going to take it to the samsung cc....... lets see what they will say about this problem

I am suffering a very similar and strange problem. I have a Dmc3 deodexed and rooted Rom with NEDLK1 baseband (3 ITA operator) since 3 months. I have done nothing special (no new apps nor flashes) in the latest weeeks. I have never flashed any other ROM. But 2 days ago I saw NO service. I have correct imei, could even surf the web but no telephone functions. Rebooting the phone did not work.
I thought of a SIM card issue and yesterday I asked my operator for a new sim. While I was waiting the new sim to be enabled, today I pushed in my Note 2 another SIM by another operator. After some hours I had the same trouble with this SIM.
So the problem is the Telephon. I don't know if hw or sw, but there is an issue.
Now to see what may be, first I changed the baseband Modem and flashed a stock XXDLK7 and inserted the new Sim inside. Now I will wait and see.
In case of continuing issue, I will try and go back to full stock operations.

Hello guys. I had the same problem, and it was a hardware problem. The solution is really simple: put onto the left of the camera, inside the chassis, a small piece of papero of 3 mm. It's enough to strenght the connections of the flat of the SIM card connectors to the motherboard

[Q] Problem with Signal/Service - weak Signal, breakdowns

my device now: i9195, I9195XXUCNE6-DBT
I experience weak signal and many connection dropdowns. When this occured first, after i upgraded f4ktion Kernel 1.3.6 to 1.4.5 and
an older version of Carbon Rom (4.2.2) to 4.3 Carbon Rom. Until than everything was fine, flash of rom and kernel did not made any problem.
Btw i used Odin3 3.09 and clean install (step by step like in the guides) all the time.
After some days this realy annoyed me, so i went back to the older Carbon and kernel - problem still occurs.
So i went back to stock rom I9195XXUBML4-DBT (original was UBML4) - problem still existing.
Some time later f4ktion 1.5 and Carbon 4.4.4 was available, so i tried this..still no solution.
Now i am back to stock and updated to I9195XXUCNE6-DBT, same problem.
Some research told me many ne stuff to know..like flashing modem only. I tried some, nothing helped.
After hours of pointless googleing i noticed something on my phone.When i dont type the pin, i have normal signal. As soon as i type the pin
and "activate" my simcard, the signal strength drops. So i googled again and found this:
[Bug Watch] Android 4.3 Radio Bugs Causing Cell Connection Drops On Some Nexus 4 Handsets, Fixes In Sight (not allowed to post links)
I changed the network type to WCDMA only - it helped for some minutes(not many..maybe 2-3). I changed to GSM only and i had normal,
stable signal for like an hour. But later signal loses strenght again, and i need to change network type again.
I have the feeling, that its like a reset or restart of the radio.
But now i am all out of ideas and need some help.
Last thing i can do, is to bring it to repair. But my Knox says 0x1, so maybe you can help me before i ask Samsung.

I have similar problem since ugrading to KitKat roms. I had no problems with previous none Knox roms with MH3 modem but now with NE6 and NF7 KK modems the signal swings constantly up and down from 4 to 1 bars. This is in areas I previously had good signal. Internet also keeps dropping out requiring data toggling on and off. I've reflashed KK 20+ times and haven't been able to get rid of this problem yet.
I'm not sure if pre knox modems are installable but I intend to try and reflash MH3 modem, once I manage to do a successful backup.

I solved a similar problem by downgrade to 4.2.2 Brazil NE2, knox 2. Flashing separate modem (NE2), and reflashing full rom again. No problems for now

Now you stay on 4.2.2 ?
I dont understand why some people do have problems and some not. Is there different hardware version causing the trouble ?
Give me pls some information how you did the downgrade.
-Nandroid Backup
-philz
-Odin (if yes which version)
-why did you choose that rom
I tried to, but wasnt succesfull. I used Odin3 3.09 to flash 4.2.2 (UAMF5 i think) rom and got a brick. When trying to fix this nothing helped until i tried to flash with Odin3 3.04. But all i could do was flashing newest FW again. Did not test more after that, because i was very busy.
If you say that going back solved your problem, i will try again go go back myself. I've found some information on that and when its done i give some informations.

Same here, help?
I'm having the same problem with a newly acquired handset. I have full signal on some places and nothing on others, unfortunately in my house I have no signal! So it's quite exasperating.
My baseband version is I9195XXUCNE6
Android version is 5.0.2 with 3.4.0-cyanogenmod-g92aec50 [email protected] #1 kernel
Cyanogenmod version is 12-20150306-UNOFFICIAL-serranoltexx
Would it help if I flash a separate modem file through Odin? In that case, which one should I flash?
Any help would be appreciated a lot.
Thanks

If you have warrenty left then you should go to customer service then they will change your mainboard. and it would bw okay.

Elephone p8000. I think i messed up bad.

Ok so i got the phone is stock form with android 5.1 and a few bugs common to this phone( screen flicker and poor wifi speed). I read more than a few forum posts that said flashing the rom to various other roms would fix it and this wasn't my first modded phone so i did. I am not too sure these flashes took as android looked and acted the same as well as had some of the elephone software. It did however screw up the phones imei. after a google search i reset the imei. I no longer have the invalid imei message but now i have a big NO SERVICE message. This is the us market phone. I really hope you cant somehow change the frequncy bands by flashing the rom. any help would be awesome.
Ps. the screen still flashes.
edit: ok tookjfer671's advice and flashed the us rom. it killed the imei (again) so i reset the imei. now somehow the imei numbers got on the wrong sim cards. They are backwards. will this affect anything ? they wont reset at all.
Edit 2 I guess you can mark this one as solved. The reflash with the us ROM worked but the backlight still flickers. Not a launcher issue the entire screen goes dark and its random.

http://forum.xda-developers.com/ele.../rom-p8000-version-b-baseband-l1-mp3-t3322615
Yup, I believe the US version B doesn't have any other alternative custom roms to flash...although you can root. Version A (Asia/Europe) regions have a whole lot of roms to choose from...it would've been nice if we could flash those as well and keep the baseband out of it so we don't lose network connections.
Anyways...I flashed as well a version A rom and found myself with a no connection to my network (everything else worked fine), flashed the link above and got device back to full working order. Hope it helps you out.

i'll give it one more shot. btw did you use flashtools or recovery?

Sorry for late reply...I was rooted with the A version and on TWRP recovery, flashed stock recovery then flashed B version and now on CWM recovery. All using flashtools.
