Blu C6 , no signal after root - Framaroot

Hi, so, i rooteed my phone because i wanted to install some apps to improve it, the thing is that after a while, i finally got my phone rooted, but my phone didn't receive any signal, it detects my SIM card, and my IMEI is fine, but in the information about my sim, phone number, network and that stuff appears like unkown, idk if the firmware that i installed erased some stuff about my country network, or something like that, but if someone know how to fix this, pleaaase help me, i´ve been reading a lot of forums for help, but most of them are for samsung, and they dont work for my Blu, so, if someone had the same issue and fixed it or knows about this, please help me, i really want my signal back

Sprint HTC Touch Pro cloned 2 metro pcs, no signal, phone off.

Hello there,
I flashed a Sprint HTC Touch Pro, and cloned ESN to MetroPCS. I followed this tutorial here.
http://forum.xda-developers.com/showthread.php?t=571190
First time when I flashed it, I didn't do the cloning. It was just a simple flash and I was gonna take my phone to corporate store to get the ESN registered. It was working fine, I was getting the signal and when I dialed 611, the call would go to metropcs tech support. But I couldn't anyone else because the ESN wasn't registered. Since, Corporate store is too far from my place, so I decided to clone an ESN number of my other old phone and that's when it got messed up. There's is no signal on the device. I restarted it many times but is still said no signal. I manually turned on the device radio but it still says no signal. I don't know what I did wrong. I followed that tutorial exactly as it was. I even flashed the phone with "Telus V1.04.05V Radio R" radio but no signal. Now I've switched it to the stock rom but it still says no signal. stock radio version is 1.03.15F. So if anyone out there could help me out, I'll greatly appreciate it. Thanks a lot in advance.
what??? nobody knows.
no replies, does this mean nobody knows? btw, gps aint working either. I don't know if this rings any bells. Come on people help me out.

[Q] HTC Desire was unlocked, crashed, now no GSM, help!

Hi, hoping someone can provide some advice on this, been trawling forums and no one seems to have quite the same issue...
I purchased a HTC Desire from someone who had unlocked it from the Virgin network. Had my Vodafone SIM working in there without any problems whatsoever for several weeks.
One night, under heavy use (video streaming etc) the phone crashed, and since then there has been no GSM signal, only 3G. Other SIM cards had the same issue.
At first figured it was a problem with the hardware, so sent it to HTC, but they just sent it back saying 'no fault found'.
Then I figured I'd try a Virgin SIM in it in case it had become 'partially locked' again - though didn't really think such an issue was possible, and bingo - this appeared to work - even in GSM only mode it can make calls.
So I guess I have a few questions:
If I take this somewhere to have it unlocked again, are they actually going to be able to do anything with it? It's not asking for a code, it just doesn't find any GSM signal...
Anyone else have this no 2G but 3G ok issue? Can a crash affect a phone in this way?!
Does it sound like something I can solve myself? I'm loathed to do anything too drastic as it is still under warranty.
If it helps I checked out the simlock menu and it is saying:
MCCMNC file fail
CID file fail
Which I presume has something to do with it...

Sorry, but I don't have this phone.
We all where noobs at some point and started with nothing.
The link provides a step by step guide, so trowing your arms up and saying i know nothing - help me wont cut it here am afraid.
Get your **** together and learn how to follow instructions.
If you run into problems, try again, only if all else fails come back and ask for help.
This sounds like a firmware issue. Did you look around for the proper firmwares to flash.. remember don't flash firmwares with an unlocked bootloader. Flash before , then unlock then root. Flashing firmwares on a unlocked bootloader bricked our Sony play. I have since relocked the bootloader and flashed over the UK firmwares. Now we get 3g. Before this we were stuck on 2g (edge). Be careful and good luck

S6 (G920F International Version) No Network Selection/NO SIM DETECTED

Hello,
A friend of mine has a new S6 which is unlocked to work with any network/sim. The phone was working perfectly for a few months.
Now for some reason, it gives the message that no sim detected. Signal bars show up. But no connectivity.
The option in settings Select Network Operator is gone, and no longer there.
I have tried re-flashing stock 5.1.1 ROM and still the same problem. Tried flashing previous 2 modems and got the same error, so flashed back to current one.
Current Baseband: G920FXXU3QOKN
Kernel Version: 3.10.61-5896496 [email protected]#1
Another thing to note is that the phone shows signal bars perfectly, even though there is the no sim message. Also, on removing and re-inserting the sim, it reads the sim and asks to reboot, after which it comes to the same situation.
Any help would be appreciated.
Thanks,
I have same issue, and would gladly fix it. :/

IMEI was reset to 350000000006, then some Russian guy fixed it with Z3X box, SIM was able to register, but reception was awfull (lots of missed incoming calls, etc.). then I flashed some more fw and modem to check wheter it would fix dropping signal issues, and then it started not to recognize SIM.
So to sumarize, IMEI (with my EFS, not @tazaga one) is fine in the IMEI info, in SIM info everything is unknown, and mobile networks menu is missing from settings.
I changed SIM for a new one, just to be sure, and is detected only when inserted/removed, then phone wants to restart to enable mobile networks, but after restart, nothing changes.
Serial number was changed, but I corrected it in a file in EFS folder.

Ya by the sounds of it something is still funky in your efs folder
As far as my problem is concerned, the IMEI and the SERIAL number both match the inside and outside. So its not that.
Any other suggestions as to what it could be? Or how to fix?
Flash stock with smart switch but before that make efs backup ( in case things goes down )
Already tried smart switch and also Odin to flash stock. Neither worked.
Would flashing an EFS backup from another phone with the exact same model work?

well I tried to flash @tazaga efs, IMEI gets unknown right after that, but managed to boot up without custom kernel after Smart Switch initialization.
Beside that nothing changed, still no SIM and no mobile networks menu, and sadly couple hours later, phone went to a boot loop.
I took it to some 3dr party repair shop, without restoring original efs and bootable fw/kernel, they said they cannot repair it, but will give phone to some "software specialist" who may be (I seriously doubt it, according to my prevoius experience with 3rd party sw specialists (last time it took me half a day to reach the state phone was in when I deliverd it to them)) able to fix it with a 50-50% chance of fixing it.

I understand that, but I kinda doubt that no SIM issue is somehow tied to IMEI
Because with my efs backup (which was made after Z3X repair) IMEI is fine, but still no SIM.
I was kinda hoping that it could be something else in the EFS folder that made SIM undetectable, but even with your efs backup (thank you once again for it) SIM is not detected, so I guess that no SIM issue is tied to something else that is corrupted, or accidentally switched off.
I just dont know what could it be, because I was messing with service mode and codes unknown to me to try fix poor reception, so god knows what I did to put the phone in state in which is now.
Perhaps I am just trying to provide every information possible, and exchange it with others who have same issue, or more experience than me, so we can together figure out what has caused this and how to fix it, and help others who will have same issue in the future (and obviously I am not the only one with such issue).
And as I pointed out 3rd party repair shops didnt proove quite usefull (perhaps their services are just flashing/rooting/unlocking, but I can do that by myself without paying someone else to do it)
We will see next week, what will guys from repair shop say, but I am not very optimistic about that.
If nothing else I can still give some money to that Russian guy with Z3X, who fixed IMEI in the first place, I guess he won`t mind
And sorry for the OT.
This problem still going on with exact answer..
I also have same issue on customer's phone.
I've tried backup cert and efs then repair efs (on octoplus).
after repairing efs, it changed IMEI to 3500...006 but still no sim card.
Seems like I can't fix even with Octoplus.
Hopefully someone finds way to fix this asap ;(
So apparently EFS and stock firmware has been ruled out. I already tried different modems using Odin.
Anyone have any other ideas? I mean other than the Sim Not Found thing, I can't even see the network selection option in settings, and using *#*#4636#*#* only gives an error that not registered on network.
well @ariza27 made similar fix for S3...
http://forum.xda-developers.com/galaxy-s3/help/solved-siii-network-problem-update-sn-t1918601
I guess there is nothing to do but wait for developers to create something for S6.
If I am understanding that problem correctly, the SIM/Network problem in the S3 came from the SN or IMEI changing due to upgrade or flashing.
This phone has the same SN/IMEI inside and outside. And its not just refusing to register the SIM, the network options have disappeared as well. I had hoped flashing stock would help, but no cigar.
One thing though, would completely erasing the data partition, and wiping the entire firmware, and then installing stock or even another ROM help? Because even when flashing through odin, it preserved the data for some reason.
Can someone send me their EFS backup for G920F on v.5.1.1 Stock with baseband/modem G920FXXU3QOKN?
I don;t know if those things affect EFS or not, just want to be on the safe side. I want to try comparing the backup from my phone and one other and then try and restore using the 2nd one.
As far as the IMEI and SN changing goes, I am looking into how to prevent that in the first place on in the even that it happens to restore it.
Any help is appreciated.
Bump! Anyone?
Your imei number has been blocked/blacklisted because of a reason like lost or stolen phone, reported by previous owner, the only way to fix it is to replace the motherboard of the same model from a supplier on aliexpress website, there price is about $350.00 Australian dollars thats including EMS express postage,you get it around 4 or 5 working days, dont waste your money or time on anything else it won't work, I had same problem, now after new motherboard my galaxy s6 edge is working fine, expensive though.
Any luck with this issue?

The phone was purchased new. And Already spoken with both Samsung and Vodaphone regarding this and they say the IMEI and the phone are clear. The phone is in another country from that of purchase, but since there is no country lock or phone lock, this is not the problem.
And no such luck yet.

SIM card not allowed after coming back from Japan

Hello guys,
Im coming at you for a question which I can't have any answer.
I bought a Note10 Plus in October to somebody on the web, the phone was brand new (on its original sealing and packaging) and working perfectly. I was first on Three network, the phone worked, then I switch on GoMo, working perfectly too. On the 10th of November I traveled to Japan with a local sim card (Docomo) and same, all working. But yesterday, I came back to Ireland where I live, and still as of today, the phone show me 'SIM 2 not allowed'.
The phone is unlocked, I've checked with the Samsung support and they confirmed it (but didn't bring me helpful troubleshooting steps). I've contacted my carrier too who said that there is no issue on my account, and they will send me a new sim card too.
I'm not expecting it to work though, as the SIM card is working on the iPhone X of my gf, and her sim card is not working on my phone too. So it's only on my Note 10+.
I've tried to remove the sim and reinsert it, restart it, reset network settings, check the date and time, nothing to do, all go to the same error.
After making research, I tried to check some IMEI Blacklist check websites, but I don't trust them as I don't know where these infos comes from, but one catch my attention because it told me that the phone was blacklisted : https://www.imeipro.info/
All the others says that the phone is clean. Again, that's why I don't really trust it, and my carrier didn't mention any block. I'm still curious why my phone appear as blacklisted so I send them an email to try to know more.
I receive signal too, but can't send/receive calls or text, and I don't have access to data neither.
So now I have my phone with no any SIM working, and I don;t know what to try to get my phone working again.
I think I've explained all I did today, I don't know what to do more, I don't have any idea of what's going on with the phone, that's why I need your light to see if you can help me to find a way.
Thank you guys, I hope to hear from you soon!
From the sounds of it, it sounds like it's been blacklisted, that's my guess. Do you get any message when you insert the sim? I had a similar thing happen to me, turned out the guy I bought the phone off on Ebay didn't pay he's bill and phone wouldn't text or make calls anymore. O2 was the company that barred the phone, and they couldn't help me even though I had proof I'd purchased the phone from the guy, only he could sort it out as it was he's account. Anyway thankfully PayPal came to my rescue, they just needed proof it was blacklisted, carphonewarehouse did a check and printed out the results for me thankfully as I knew the guy that worked there. I got a refund and promised myself I'd never buy a phone off Ebay from a personal seller, if its a business account then maybe. Awful experience though. I hope you get this sorted.
I'm guessing you've never rooted the phone or flashed it as that can sometimes delete the efs folder which causes the phone to have no imei.
Thanks for your answer !
No usually I root all my phones but this time I wanted to keep it as normal, because tthe phone looks like there's nothing more to improve to me (except a little bbit the camera when the light is low..)
I didn't knew that it could cause such things ! I should have done that
Honestly that was the first time I bought the phone to somebody, and more of that, the phone was sealed on the original plastic with the label ''eu sim card only''. So I was trusting it, even if I know, that doesn't mean it's safe behind that.
Since I've posted the message, I contacted few carriers, like mine GoMo, and they dont know anything about the blacklisting (I was surprised) then I contacted Three, they told me that the device does not belomg to the; so they can't check.
I tried Eir, and they refused to give me infos for data protections, which I think is stupid because the phone is not a personal information who could reveal an identity but anyway. I didn't though about Carephonewarehouse, I will visit them because it seems like this is the best idea.
The weird thing to me is still that it didnt worked suddenly... I was in the flight and this is when I came back that it didn't worked. Well, maybe that was a bad hazard.
Something I've discovered yesterday more of that is when I have this issue, turning off the 4G and only allowing 3G/2G will allow me to use the data. Still no phone or text, but the phone is detecting the H+ signal and I'm free to go on the web.
Yes for your question, the issue happened instantly when I insert the card on the SIM1 with the error SIM not allowed, the SIM 2 slot works perfectly, that's what I'm using for the moment but I can't use any SD card at the same time, so it bother me. :/
Thanks for sharing your experience, then I know a little bit fore of what to do. I wanted to go to the police but I don't want to spend 2 hours there. Maybe I'll think of it as a last resort...

I just came from Japan as well I had the same problem but with my Sony Xperia 1.
I bought it from the states and I took vacation to Japan and used their sim card.
When I came back here in Florida I switched back to my at&t sim card I couldn't make calls or texts only data works for some reason I tried everything I used sim card on other phones (sim card is fine)
I tried everything, nothing worked !
I factory reset the phone and it worked, fixed the problem (it's strange because I used Galaxy s8 also with that sim card and it's working fine)
My Sony Xperia 1 had similar problem to yours
I don't know if this will help you to be honest but I had kinda same problem.
Hope you solved you issue.

Thank you for that, I've tried this yesterday after a backup, I used the sim card with the phone completly as new (well, I've restored it from the settings, so I don't know if it was the good way) and it didn't worked.
I think I will try carephone warehouse as jadaress1 requested, it might give me lot of infos there. Im also starting thinking that the phone is carrier blocked, but I can't see any reason why the phone was new and already unlocked so I don't see any reasons...
I'll let you know
