Hello, i recently sold an S3 GT-i9300 on ebay. It was rooted but had stock rom and kernel installed. Worked absolutely fine. The fella that bought it, said he flashed CM10 on it, and had no signal. Then he flashed a stock ROM. Still no signal, So i can't figure out what could be wrong with it. He has sent it back to me, and there is still no signal. i tried 2 different sims. i'm hoping i can fix it. either way it was working fine before he got it. its a european model, and he has installed stock samsung for Nordic countries, baseband XXEMB6, build XXEMC3. i live in uk and bought the phone in uk, so would this make any difference? i have even tried ARIZA patch with no luck. Can anyone offer some help or insight please? im really stuck. Thanks.
Basic is user failing to read the faqs and guides before flashing .
Why on earth you took it back as the buyer is at fault for modifying the phone .

Have u tried flashing stock rom?

Hello man!
[2 Questions, 1: get back stock rom]SOLVED maybe next time i better get peanut butter of my eyes first.. Thanks for talking about!
O2 German Ace S5830 stock rom PDA:XWKPY CSC:VIAKP1 BASEBAND:XWKP8 (found on sammobile, its the one from 1969...) flash first other multi-csc rom and set to VIA for future kies updates.
Get my ace a few days ago and flashed sth here and there without thinking about getting back to stock rom later. Had a HD2 some time ago where you get stock rom for all country and provider on htc homepage..
So im sitting here and want my ace back to out-of-box state but no rom ive found seems to be right. looked on sammobile.com, searched xda and at last tons of google results.
didnt know what the name of stock rom was.. only baseband XWKP8 which i only found on some russian site and that it was android 2.3.3. doestn want to try unless sbdy can say me its save..
Got my ace from O2 Germany without contract, so no simlock etc..
My intention is to get some o2 germany rom back, so i can update with kiez to latest. tried a lot of roms from sammobile, modified csc to DBT (germany) and VIA (should to be o2 germany csc code).
[2 Question unsolved]
Had problems with several ROMs with wifi / 3g network, couldnt activate/deactivate or wifi is not getting IP, need to reboot every time to fix that.. Which baseband is best for which rom / my country? (gingerbread, ics, etc...)
Maybe i am spoiled from HD2.. sry for that
PS[Maybe irrelevant: now flashing leaving EFS blank, seems to work fine too, dont know yet if better]: Something else.. Instructions for flashing rom with ODIN are confusing me, sbdy say dont touch PDA others say dont touch EFS. Flashed all the time not touching PDA, putting boot to boot, code to phone, csc to csc and modem to efs. Still have my IMEI so all right or just lucky? Read all the newbie guides (which were very confusing) imo i read sth about backup imei but i am not sure as if and how.
Hope you can help me, thanks for all guys reading and thinking about.
i have Samsung Galaxy s2 gt-i9100(rooted) and suddenly my network signal was missing. and i dialed *#06# and display no imei and unknown baseband . so how to solve that problem?
gt-i9100
android version - 2.3.4
baseband - unknown
kernal version - 2.6.35.7-i9100xxkh3-cl479037 [email protected] #2
No EFS backup ? Try flashing some stock roms. If that doesn't work, service centre or local mobile repair shop; they have equipment to write the IMEI back to the device.
Yes sir i have i have tried to restore but it didnt work
neddinary
Sir give links to flash rom
plz
Samfirmware. No, I'm not going to give you a direct link; did your last slave die of overwork per chance ?
same problem
what firmwere should i download if it dosnt show up any baseband version????
Did anyone gotta solution?? :crying:
Try all the firmwares for your country/carrier (not 4.0.4 though, just in case you flash & forget then do a factory reset. If you've flashed a couple of those & your IMEI hasn't returned, it's fairly safe to say it isn't coming back; take it to a local mobile repair shop, many have the equipment to re-write the IMEI to the device fairly cheaply.
Did you manage to sort this? I was asked to look at a friends S2 which was showing no IMEI number, and I managed to sort it....

Spill the beans then; what did you do to fix it ?

Ah.... this fone was completely stock, still running Gingerbread 2. whatever!!
So.... all using Odin....
I updated-no joy
I rooted-no joy
I flashed newer custom ROM-no joy
Then, I tried flashing Stock 4.1.2, and away it went!!
IMEI number replaced, fone now working, friend well impressed!!
The files are I9100XWLSW_I9100XXMS2_I9100XEULS5_HOME.tar.md5
I'm not sure how to post a link (perhaps someone could show), I got them from YouTube, but have them if anybody needs them.
But if you Google for that, and you're on UK S2 I9100, you should be fine!!
Hope this helps some people, please bear in mind the usual : "I cannot be held responsible for any damage caused...."
Hello everyone,
Firstly, I apologize for my bad english.
so my problem is that : there are two week ago i buy sg3 (i9300) from swiss, and when I got home (Algeria) I realized that I had no network. so i instal a root on the phone, and I used galaxy sim unlocker, voodoo, the ariza patch,regionlock away. no network at all.. . so I understand the problem. xxemg4 modem is intended for the European sim only, then xxemg4 use a new format of efs. so it's impossible to unlock the network for the moment.
So I ask you one thing. xxemg4 modem replaced by another modem supporting efs "v2" ... Algerian for example. would be the solution? whether helped me solve this problem please.
Thank you kindly help me good evening.
No, you cannot unlock the phone yourself. You cannot flash an earlier modem now you have efs v2.
If you flash the right modem for your country the phone might get signal, but it will have to be EMG4 or after at least. Unlocking will still need a code provided by the original swiss mobile network.

thank very much for your answer.
can you link me a mirror for a modem unbanned and supporting efs v2. or can i updating my gt-i9300 to 4.2.2 or 4.3 and use modem ubanned ? . so please link me a modem or a solution to unlocking the network.
thank you
Hi Everyone,
I am typing this query under severe worry about my galaxy s3.I am dying for any help experts would be able to provide please.
I had 4.2.1 stock ROM installed on my s3 and im a very frequest visitor to xda for custom roms.
I downloaded the Android revolution 40 ROM for S3 and installed it after taking a backup of my stock ROM using recovery
When i booted into the new 4.3 revolution i was getting the error " not registered on network".
I searched the threads here in xda and did everything like ariza patch and flashing mg4 modem but even now the phone was not able to register to network Airtel
the most strange part is i get full signal,I have baseband and also IMEI still it doesnt connect to network
now the most strange part.If anyone calls me they are able to get the ring but im not getting any notification and the phone is idle.
I tried to search for network from mobile networks but it gave msg as "error when searching for network"
I took the phone to Samsung service centre and they told me they will reinstall 4.1.2 and it will work
I waited for 2 hrs and they told me its done.I put the simcard in and again i have same "not registered on network error"
Im sure they dont know how to sort this issue and the only thing they did was reinstall firmware which did not help
Im very afraid now that my mobile is permanently gone and i feel very bad for this
I hence request the experts to help me and bring my device back to normalcy which will releive me of stress mentally.
Please help ASAP.
Thanks in Advance
VJ

Hi Sir,
Many thanks for youre reply.
Today i got a call from the Samsung Service Centre that they are unable to fix the "netowkr not found problem"
They told me that there is some problem with the motherboard and it will cost 9000INR which is approx 155 USD to change the motherboard
They told me that is the only way the phone can get the network back and there is no other option.
I read your reply and I will download stock 4.1.2 from sammobile and flash with odin at home and flash the patched MG4 modem today.
That is my last hope as i cannot afford 155 USD for the motherboard as it is 1/3rd the price of my mobile.
They din charge me anything and gave my phone back.they have installed 4.1.2 stock I9300DDEMG2 modem and build number I9300XXEMH4.
I will post tomorrow what is the stauts of my phone.
Many thanks anyways for your help,this is my only final attempt to save my S3.
I hope it works.
Many thanks anyways for all the help

Hi Everyone,
I would like to inform you all that finally I have revived my S3 and it recognizes the network now.
I flashed the patched modem on my stock Indian firmware and my IMEI became 0049....
I found out that my SGS3 was bought in UAE by my cousin and hence i downloaded the 4.1.2 stock UAE firmware and flashed it.
Again no signal and no network
Finally as a last step before giving up i again flashed the patched modem and restarted the phone and it connected to network
My baseband is back,IMEI is back to normal,able to connect to network and everything works now
The only glitch now is that the serial number is 000000
I dont think it affects the phone in anyway.
Aslo one more question,can i update from OTA software updates in Samsung or again my phone will have "no netowkr problem"
Kindly advise
Many thanks anyways for all the help
OTA updates only available to unmodified handsets, running unrooted stock rom, recovery etc. All this and more is in the general forum, sticky threads -go read them.

Hey guys, I was recently on a custom Rom, which i liked but had so many bugs
I heard good things about the newest 4.3 update, the ones with all the bug fixes so im trying to go back to it
I flashed a really old 4.0.4 version, which for some reason was in dutch? and it had taken away my Imei and luss i couldnt change the CSC within the menu
Ive tried countless other firmwares and ran into nothing but trouble, I tried the leaked 4.3 firmware which was a Irish vodafone version and i couldnt do anything with that
Sam mobile is pretty much useless with the new host, can someone please give me a link which has the right firmware ( Unlock Galaxy S3 gti9300 ) normally i flash BTU. So yeah, The right firmware, where I can update to the latest 4.3, quick download speed and a firmware which has everything included ( I.E IMEI, Signal Etc )
Many thanks, Jack
You'll need to understand the basics if you are going to repair what you've already done to your phone.
Flashing yet another rom won't fix it, if the 4.3 firmware didn't.
You can't repair the imei, unless you have a backup of the efs folder. Instead you'll need a repair centre.
Start with reading the sticky threads in general forum, in particular efs 'know this stuff'.
