[Q] No GSM signal after repair??

Hi to everyone
I bricked my phone after flash. It was compleatly dead.
The problem arrives when I collect the phone from repair shop.
They did not charge me coz the phone don't see any network. I thing they resurrect my phone and flash it from basis.
Phone was unlocked by code before I bricked it.
Now everything is working fine but after inserting a sim card it saying "no network"
Any ideas or sugestion??
Thanks
When you send something for a repair and get a non-working thing back, do NOT mess with anything and send it back where it came from. They were supposed to repair it, huh?
Thanks for a quick reply
The phone was compleatly dead after my flashing, it was not reacting at all. I was flashing with unofficial firmware so I'd think that sending it to LG it's not good idea.
So I give it to repair shop. After a week the phone was ready but with no GSM. They said "it's only this what we can do about it".
Second repair shop tried to flash it with official T mobile firmware. The same- no gsm.
So I'm left on my own.
Well, phone without GSM is useless.
How did you brick it exactly? What were you flashing and how?
What is the ROM installed there now? What is the baseband version? Is there any IMEI shown in phone info?
Yep, but is good for wi-fi
I was flashing with LG official software and it fails. I forgot to enable LG virtual modem driver. The software utility hangs up for 4h. I woke up pissed off and i took battery out, I know, I'm genius. After that I lost ability to enter emergency mode, even fast boot was not working. Oh my Lg R.I.P
I was updating from 2.2.2 (KDZ flash) to 2.3.3 (LG update tool)
IMEI is showing
Baseband AMSS6038
Rom LG-P500-V20e (2.3.3.)
One more thing
When I collect phone from repair shop the IMEI was 0 and they change it to normal, like on the label.

Should work... The SIM is good? (Try another one ) Is there some GSM signal around?
Other than that, you can try to flash again via LGMPD or whatever. If it does not work, then brick it again (you have the know-how apparently ) and take it to LG for PCB replacement.
Send it to lg service centre..they have more knowledge and experience den repair shops
I'd try 3, vodafone, orange and O2 sim card
Signal coverage in my area is good
I was also flashing throught LGMPD
When phone was in repair they opend it. There are marks on screws and on the top from prying tool. You think I should try send it to lg??
Well... if you want to use your phone as a phone, then... Ask them whether they would charge you and how much.
prying tool

OMG... is that the job of the "repair" shop?! In that case...
I know. They should sell potatos on the market, not fixing the phones.
Oh well. I'll call later to lg and ask about that or brick it again, cover marks on the screws and hope it'll go throught.
Thanks a lot for help

One more thing - does the current IMEI match the one on the box you got with your phone?? Cause what I suspect that they took some ****ty broken board from a phone with non-working GSM and did put that into your phone. Kinda doubt the morons who are using prying tools would know what JTAG is and how to work with that.
@Omen-am: I have the same problem, used the same flash methods and also got my phone bricked. Go someone on ebay to jtag resurrect it and now I can switch it on, have already flashed all the versions of firmware that used to be on there to the latest GB but none of them recognize my sim card (which work fine in my old phone). So now I have a perfectly working "mini-tablet" working fine with wifi, bit no gsm service. So my question is, have you been able to fix yours? Do anyone out there know of a fix?
Thanks

The phone had android 2.3 operating system which was upgraded by the dealer to 4.0
i used upgraded from sony web side and from software nothing work
it's not working. It's been like this for around 1 months now, and I really want it to work! And i've tried reseting, updating the ROM, changing SIM card and put in a totally new SIM card and it's work but signals:crying: drop every time, oh i am so upset.... SIGNAL DROPS EVERY TIME !!
dealer refused to return the phone , i bought the phone from the dealer so it's under seller warranty
the sony service center in india is so poor that they will steal my mobile parts if i will take their help.
i have shown the phone to some local mobile repair experts and some says that network ic is the problem , emei is the problem , some say the phone might not unlocked , some say that do not have the files to solves the problem because the phone is imported.
Is there anyone who can tell me what is the problem with this cellphone

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

Unable to connect, try later

Hello XDA,
I have recently bought a Samsung S6 Edge (SM-G925F) from ebay.
On arrival and using the phone i noticed some red text saying 'Kernal is not SEandroid enforcing'. I assume the phone had been tampered with and i figured the best course of action would be to install stock software on the phone, so i went ahead and did this.
I installed the following firmware : http://www.sammobile.com/firmwares/download/57658/G925FXXU3COI9_G925FBTU3COJ1_BTU/
Now i have a new issue, the phone no longer can connect to networks.
When i try to connect to a network i get the following message 'Unable to connect, try later'.
P.S
I have noticed that the IMEI number on the back of the phone does not match the IMEI number found when dialing *#06#.
Thank you for reading

You better try to get your money back if he didnt say something was wrong with it (hope you used paypal or a creditcard). The device is probably rooted and or a custom rom was running on it. What imei do you get when dialing *#06#? is it all zero's?

No, the imei number is very similar but with 2 different digits.
The seller is willing to refund me.
Such a strange problem though, I almost wish I could understand how to fix it but I guess that will never happen now.

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.

Dude it it can be fixed its just you need octoplus box or z3x box

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.

No service and mobile network. Really no fix? :(

Hii... Have been searching forum but seems like no one has the answear

Has anyone got any solution of this? It's been quite a long with this issue, I've searched a lot of topics but no solution.
I have the same problem. Phone don't see simcard somehow. Flashed latest original firmware works for 1 min. Pull out trace with sim insert it again works for 2 min and stops working. When it works for small amount of time i think IMEI its not blocked and almost sure its software issue. Yesterday flashed different roms and CSC and modems no luck. SimCard changed for new one. Have someone some clue what to do ? I can provide logs if needed.
After instaling Samsung Phone Info app from market gsm wen't back online. Probably a coincident but when I go to Hardware screen ther was no modem model. I tap it few times. Close apk run it again modem went show itself after a while GSM signal is back.
After reboot no signal again. Then i make magic with phone info apk again and signal want back.
This apo make some sort of device discovery and reset modem device / driver or this is pure luck.
