thanks all, i have sloved my problem. I also want to share my solution . I took uproom and hard reset hope if someone face to the same my problem, they can read my post hii

I've got the similar problem. My phone says "please put the sim card into the phone". This happened after I flashed Juwes 5.1 custom rom. My IMEI was corrupted after flashing, then I managed to restore it after I edited the nv_data.bin. Now I have an IMEI number, but the phone cannot recognize any simcard.
Reflashing to the stock rom with Odin doesn't help. I've already tried XXJVQ, now I've got XWJVI. Neither hard reset nor flight mode helps. I've already tried to delete nv_data.bin and nv_data.bin.md5 and reboot, but result is still the same. I cannot find any tipps for solution. Have you got an idea what could I try?
Here some information on my phone:
german version, not branded
*#06# shows the right IMEI
*2767*4387264636#:
Sellout SMS Off
Pcode: GT-I9000HKYDBT
Mode: Prod
*#1234#:
PDA I9000XWJVI
Phone I9000XXJVO
CSC I9000DBTJV2
everything seems to bi OK but it doesn't work. I have already found a topic in your forum about SIM initilializing bug, and somebody suggested to flash the following ROM:
(Rom) I9000 Hybrid / No TouchWiz *9/7/2010* for I9000
but its no longer available. EFS backup doesn't exist, as I deleted it some days before That was a big mistake.
Now I have to stay without my phone over the weekend

Hi,
There was no need for you to flash to stock ROM after installing Juwe's ROM 5.1. I am currently on the same ROM and faced the same problem. All i did was flash the JVQ modem via odin and my device recognized the SIM card. Hope this helps.

Thanks for your reply. as I'm now on stock rom, I've already flashed the stock JVI with phone and csc over ODIN. But this didn't solve the problem.

The problem is solved, After restoring my IMEI I was stupid enough, to put the sim the wrong way into the phone Now its working. Thank you guys.

hi tuteary Vtd, what do you mean by "uproom"?? i have the same problem, could you please give some more information about your solution?
thanks,
sami

(yet another!) no signal after unlocking sga gt-s5830

Hello
From what ive seen on here and other forums this is a very common problem with no real solution!?!
Am thinking that theres no fix but thought id ask before i give up so here goes!!
I have a samsung galaxy ace gt-s5830 which was originally on o2 uk that i wanted to use on vodafone uk
I managed to root the phone and get the unlock code from the phone via the bml5.img and the XVI32 Hex Editor
I then unrooted the phone put in the new sim and entered the unlock code
The phone now says vodafone uk on the lock screen but doesnt have any signal!?!
It still has an imei and baseband number and ive checked that the imei number isnt blocked
Ive also checked that all locks are off via samsung code *#7465625#
I have flashed the firmware to UK Gingerbread 2.3.6. using odin 4.38 and a one package tar.md5 file, wiped caches and rebooted etc
but the problem still remains!?!?!
Other than the no signal problem the phone works perfect and also when i take the sim card out theres signal?!?!
One other thing When ever i reboot the phone /system/csc/o2u/system cant be found although ive read this has nothing to do with the signal problem?!?
If anyone has any ideas or needs any further info then please let me know
I am new (probably pretty obviously!) to all this so please keep replys as simple as pos!!!
Many thanks
Matt

hi matt first of all..
1. did you try another firmware?
2. you follow correctly the method to flash firmwares on odin?
seems to me that your download was corrupted, or you didn't flash properly on odin.

Its not a good thing to touch the bml5 partiton wich contains our imei ... even tough u unlocked it successfully you may have made some files corrupted wich can cause that ...
A major way to know this is ... does your previous sim aquire network?
And just to inform the error message is really not relevant ... csc function is to "inform kies" so it can do update your android version to the rom of your Country/Carrier.

Hello and thanks for both your replys
Firstly to answer matias.s
These are the instructions i followed to flash the fw
Flashing the Samsung Galaxy Ace GT-S5830 Firmware
1/. Enter Download mode by pressing and holding Volume down, select and power button simultaneously
2/. Connect phone to computer and open the Odin Multi Downloader v4.38 (it should show the com port it is connected on)
3/. For OPS, browse and select Cooper_v1.0
4/. For One Package, select the MD5 flash file attached and click start. (The attached firmware is for UK Gingerbread
2.3.6. You may use any firmware at this stage)
5/. Enter Diagnostic mode by pressing and holding select and power button simultaneously and clear caches
6/. Root the Samsung Galaxy Ace using the root.zip update
7/. Download, install and Open Root Explorer (File Manager) from Android Market
8/. Add Directory csc/system/XEU/system and move files over from CSC/system
9/. Enter Diagnostic mode again by pressing and holding select and power button simultaneously and clear caches
10/. Unroot the Samsung Galaxy Ace using the unroot.zip update
11/. Enter Diagnostic mode once again by pressing and holding select and power button simultaneously and clear caches
Odin came up with pass at the end
The only instruction i didnt follow exactly was 8
Firstly it wouldnt let me create the folder and then when i went into my directory there was already a /system/csc/XEU/system which had files
Could this be the problem?!?
And to answer snowpluralism
The sim im using works fine in other devices and as i said in the op the phone even has signal until a sim is inserted!?!
Update...
I flashed the fw again with a vodafone one package md5 via odin Odin passed the download and the phone is now branded with vodafone logo and apps
It is now on android version 2.3.5 build number gingerbread.buks but still has no signal
One strange thing when i first turned the phone on after the download it updated and downloaded vodafone apps and in the phone status said it was connected under mobile network state even though it still had no signal?!?
Thanks again for your replys and any ideas again please let me know!!
And thanks to snowpluralism for explaining about the csc error That explains why kies cant update my fw!!

Highly Challenging Network Issue

I've had this samsung galaxy ace s5830i (my first android) for 4 of the most frustrating months now.
The problem first started with the phone being stuck on EDGE regardless of signal strength. I tried flashing it with new roms but had zero success. I tried manipulating the menu under *#197328640# but that led to a dead end as well. Every time I tried to select WCDMA only, the network bar changes to a "circle and cross" type of thing. I tried to dial *#7465625# to check for network locks but everything reads off i.e. no locks of any kind. Finally, I tried to select a new radio band by dialing *#4636# but that operation crashes a "com.android.phone" everytime.
So in summation, service mode changes don't help and flashing the rom doesn't help.
Recently, I to switched one of the strongest networks available (other than the one I'm on) but the phone is stuck on "emergency calls only" mode. When I try a manual network search and select the network to which the SIM card belongs, I get and error telling me that the SIM card can't register onto the network.
I have used these SIM cards on nokia phones and other samsung galaxy ace devices and have experienced none of the problems listed above, even in remote areas. The support guys of my network say nothing is wrong with my account.
So there you have it. Is there anything left that I can try?

Flash the latest firmware available for your region in Odin. Because this will wipe and reinstall your modem and other data as well as your ROM. If that doesn't do it then it must be a hardware problem, isn't it under warranty?
By the way just to rule this out, check you haven't lost your IMEI number with *#06# as this can also cause network access issues.

The IMEI ok. What section of the operating system controls the com.android.phone process or the phone's ability to select or switch bands? In my lay man understanding, this is where the issue lies and every time I flash, this region remains unchanged

Try changing manually CSC of the ROM.That's the most reasonable thing that I can thing of right now...if it don't work after changing it go to samsung service..

If you mean the *#272*IMEI# trick, then I already tried that and samsung has no presence in my country so no service centre to speak of

I have your exact same problem .
and I've been looking for a solution since last week , i'm starting to think its a hardware problem.

I "worked around" it by flashing the phone with a rom that locked the device and then reflashing it with the original rom. At least now it picks network but the other problems haven't left i.e. still no 3G and I can't edit any menu under service mode et al.
On another note, if you have the time, try flashing with different modems... maybe a miracle will happen

There seems to be something wrong with basebands of latest stock roms.Try switching aeroplane mode on and then off.I regularly lose signal..and get stuck without signal until I reboot.

Make sure of your phone model (Under the battery) because there is GT-S5830M GT-S5830C and GT-S5830I.
In my case, I have GT-S5830M and the only modem that worked for me is PHONE_S5830CVJKL4.tar.md5.
Maybea changing the modem will fix your network problem.

You can use a file called Odinatrix (found somewhere here on xda) to split single firmware files into pda, modem and csc. I, on the other hand, still get a circle and cross whenever I set the device to wcdma only. The interesting thing is that setting it on auto picks up 3g but very rarely (twice in many months) and for a short time (like 3 minutes). still looking for answers

Regarding the modem, I found a link for you:
http://forum.xda-developers.com/showthread.php?t=2010116
These modems are all CWM flashable .zips
You say your country isn't officially supported?
It would help to know which country that is.
Good luck though!

A guess based upon the last reply .
Your EFS folder is wrong or damaged .
Suggest you flash the correct stock firmware that came with the phone .

[Q] Help needed, stuck after updating firmware (emergency call)

Hi,
Well my device which is S5 mini g800f working fine, since I have changed the firmware which was old like build on july so I tried to installed latest, but now there is emergency call showing, also I have tried manually and automatically to register on the network but it says unable to register to the (---network). I did it coz my device was not showing LTE network. However my sim supports the 4g and was working on S4 i9505. I have searched on Google and look out many threads on XDA but no success until now.
The biggest mistake was I didn't looked the firmware which was already there and was running with 3g support. I have tried these EUR-G800FXXU1ANL1-20141226162921, SER-G800FXXU1ANG1-20140709112536, MAT-G800FXXU1ANI3-20141218172328. Then I have installed Custom Lollipop but no success was there too.
So now any pro's here who can understand my problem ? My imei is showing, is there any procedure where I can put the imei and it will let me know what was installed on stock :crying:
Sorry for being noobish..

Please any buddy give me suggestions that what should I do ? Or should I look in the specific section of XDA forums ?

Its is mentioned mate what I have written, I said my imei is showing that by dialing *#06# I can see it, because there is a problem where the efs folder corrupted or gone you cant see imei or imei appears to be in these digits 00000 especially by installing custom roms. Anyways my only motive is that I know the imei and how ever I can see it too, so is there any procedure where I can put the imei to the website and see what was installed on stock. Because I dont have the box so I dont know which firmware was there when I installed another rom to get LTE, because it was working properly as I said in my earlier post.
Problem is due the baseband I am pretty sure which is not matching, this is the reason because I cant connect to the network---error msg (Unable to connect).

The baseband firmware is included in the firmware packages that are available on sammobile (.tar.md5 files). If you flash the firmware package with Odin, also the baseband firmware (contained in modem.bin) will be flashed.
If you have problems with a newly flashed stock firmware that were not present with the original firmware it might be because of one of the following reasons:
You flashed the wrong firmware. I don't think that the version name of the original firmware is stored somewhere. Instead check sammobile for the correct one: select the correct phone model and your country. EUR, SER (for Russia), MAT are country codes, choose the correct one for your country, the search function on sammobile will help you with that. You can also try Kies for restoring the firmware. Maybe that is able to determine the correct firmware according to the IMEI or some other information stored on the phone.
Maybe your EFS partition was changed and corrupted. The EFS partition is the partition that contains the IMEI and other information like calibration files that are specific for your device. If any of the files in this partition is damaged, the phone might not behave correctly. If you flash another firmware the EFS partition normally is not changed.
Your hardware is defect.
I guess that you simply flashed the wrong ROM. Otherwise the problem will be hard to fix.
