Hi,
I recently got my Chinese version Lenovo phone back from the service centre because of faulty reception. They sent it back and said it was ok. I couldn't believe it, I have tried everything.
Indeed it is now ok but I noticed they have replaced the stock software with: P780_S125_130529, P780 V15 2013/05/27.
Before, I have tried every ROW and Chinese ROMs and SLX ROM with combination of all modems available and my reception was still bad and I was loosing signal.
Now, is there I way to:
1. Backup my whole current stock software from the service center
2. Backup only the modem from this current software so maybe later I can use it together with another ROM?
I honestly cannot believe how it is possible that it works now. However I have not tried v15 modem myself with SLX.

Hi everyone,
Today I updated my CyanogenMod Rom to the nightly of 05/13, coming from a nightly that was approximatively one week older.
Once I updated the Rom, the phone asked me 5-7 times for my Pin code, and I didn't succeded in acquiring cell signal . As I read from suggested in a thread (can't find it again sorry), someone suggered that the Modem wasn't right and to update it with the GetRIL app', so I did it, and the app' told me that indeed my radio modem wasn't compatible with my baseband and that I should download the modem it suggered. I did it, (the app' also proposed a backup of my current radio in case of bad flash, so I was kind of reassured), the flash was succesfull, and to try if the pin was working again, I rebooted my phone.
It didn't work at all, so I decided to revert the modem to the old one using the backup the app' created.
It was a disaster, I lost my IMEI, my baseband, and so on. I then decided to flash a stock firmware to repair that using ODIN, and it worked, I regained access to my IMEI, and to my cell phone signal. I then decided to flash the cyanogen nighlty from 05/11, but it broke my IMEI and connectivity again. Am I the only one experiencing such issues? It's not my first flashing a ROM and I followed scrupulously the procedure on the Cyanogen website, so if someone had a solution about it, I will be very glad.
Thanks for reading
Hi,
Firstly thanks for time and sorry if this is a noob question but I only have a fairly small amount of experience regarding custom roms.
Here goes...
I have changed the rom on my phone about 5 times over the last couple of years and never had a problem. I have the latest version of teamwin and I'm currently running Android Revolution HD 50.0 by mike1986. This rom works great as have all the other I have used in the past ie Cyanogenmod, Omega etc but the problem I am having is over the last 4 months I am completely losing network and even if I try to search for a mobile operator my phone can't find any unless I run a full power cycle.
I have been reading as much online mainly xda-developers to find a solution to this problem but I'm afraid I'm now just running into a brick wall. I understand this could just be a hardware fault but I have read somewhere that I may have the wrong modem installed for my phone.
How likely is this? Can having the wrong modem cause intermittent problems? Also if this is the case where the I find a tutorial on correcting this issue. Plus which modem should I be using in the UK?
Again thanks for you time and any help would be much appreciated.
Mike
Do a full wipe and flash the latest stock firmware for your country, then factory reset.
Test fully before you install or restore anything. If it is still the same then probably hardware.

ok, Will do. I am just waiting for the UK stock firmware to download. I left it downloading while I was out this afternoon and for some reason it failed and now is asking me to wait an hour before retrying
I'll let you know if this solves my problem.
Thanks
ok..
I managed to get hold of the stock firmware from another site. I first installed a version of ICS so I could run triangle away properly after rooting with CF auto root as without doing this I couldn't reset my binary counter even after flashing stock recovery. Then I installed the latest version of JB and ran the official Samsung update to get my phone up to the very latest Official software with device status official.
So now my phone is completely back to if it just came out of the box. I finished late last night and installed nothing but WhatsApp. Then at about 3pm today again I completely lost network and couldn't restore in without a full power cycle. Even searching for Network operators in settings couldn't restore the connection. I can't think of anything else to try.
Any ideas what to try next please?
P.S. The firmware I installed is as far as I can tell for my location. I'm in the U.K. and I'm using the stock BTU version on baseband version I9300XXUGMK6
the same i9300 problem

But I have trust that its not better solution (at least for me).
So if you find some solution, please dont forget reply here.

O2 by any chance? .. if so it's a network issue. It happened to me a while back but cleared up after a day or two.

This is exactly the issue I have now - I can get some signal, but can't get anything in terms of using 3G/Mobile data :/
Hello,
I've been facing this problem for days now, tried almost everything and still no luck, so I'm sorry if it's been asked before, but I'm truly hopeless.
Right now, my SGS3 works only on stock ROMs. Every time I try to install a custom ROM (JB or KK) I have a problem with the signal - either baseband, IMEI and everything is "unknown", or everything is good (IMEI not "0049...", there are full correct APNs) but it still displays the "error while searching for networks" message.
Fortunately (as I realized on other threads),I can always go back to square one, flash a stock 4.3, with no problems with IMEI or anything, but, you know, stock sucks.
I tried installing every modem I ran into, but nothing helped. Is there a secret step from stock to custom on samsung devices I'm skipping (I'm an ex-nexus user...)?

Same problem, no solution until now

When you install a custom rom, based on samsung 4.3, do you have emergency calls only/no network?
If yes, install Boeffla kernel 5.3/or beta 5.4 because Boeffla is a patched kernel i.e. it can read patched modems, and then install a patched modem .
From the on you will have your network (no emergency calls/no network problem) and signal should be good.
But first backup your EFS and store it on a very safe location, you have ann app for that, k-Tool on Playstore (requires root).
Ok, so I used to have cm11 installed, but it got sort of buggy in the long run.
I decided to try Foxhound rom, just for kicks... When it was finished installing, I got the default IMEI and the phone wouldnt connect to the network. I found a way to fix this (without backing up my efs folder), by installing an old rom. After that, I installed ef extreme rom (the one with the s5 ui).. It was supposed to be the most stable and smooth rom... But the camera and hotspot wouldnt work -_- ... I never understood why.
Anyhow, the problem is, now that Im trying to get off that crappy touchwiz rom, I NEVER get service anymore. My IMEI will always go blank.. Now the baseband goes "unkown" too (which hadnt happened before)... For ****s sake, I was trying to go back to my old cm11, and still, crazy IMEI... However, if i install the old rom all over again and the region modem: boom, mobile network works again... I dont understand why it fails to work after i have gotten it fixed over and over again...
I even made a backup of my efs folder when the mobile network is working (on the old rom.. Revolution HD)... When i restore it on newer roms, the IMEI and everything comes back.. however, it wont let me access the network (radio off?)
WTF can i do? Im desperate for help, please!!
@niko: standard is to get your actual firmware from sammobile.com & flash it with Odin … to get a stable base.
Your device serial number is probably corrupted. You can use service box to fully repair this issue. Or you can flash Ariza's patched modem. It will work but your efs folder will be permanently screwed and you will be forced to flash it every time you flash a new firmware.

I had my s2 hard bricked and now i got a new motherboard for it, the thing is that on all stock roms (2.3 and 4.1.2) the phone works perfectly but all the custom roms 4.4 5.0 6.0 the cellular does not work, it gives me no service, tried flashing modem from cwm but no change.
i also tried different recoveries etc but custom rom no service
sometimes in custom rom imei used to be blank but it comes back after reboot, in stock no issues at all
any idea what im doing wrong or is there something up with the new board?
thanks,
Update
I was searching and I read somewhere that installing NeatROM by Sale will help, i downloaded and installed it, the good news is that cellular works and i have full 3G access.
Question: How to proceed further?
i could experiment but the thing is that if i flash a non-working rom (no cellular), i will have to flash stock from odin and start all over again
any ideas?
Update 2
i tried NeatROM and it worked perfectly, then i tried installing slimLP and boom, no service again, this time,my IMEI was blank too, so now i'm flashing stockrom again.
any idea anyone please?
