[Q] Help! Phone not receiving any signal and missing softwares!

Hello!
Am using Samsung Galaxy S i9003 running on android 2.3.6
My phone is not fetching any cellular signal even though sim card is inserted in it. It is asking me to insert sim card when I check for mobile networks. After a thorough check up what I found is the IMEI number is missing. It is showing blank pop up when I check in for IMEI (*#06#).
Also what I've found is:
PDA: I9003XXKPQ
PHONE: Unknown
CSC: I9003SERKPQ.
So I thought this cellular signal problem could be due to missing "phone" file in the software of the operating system. So I flashed a custom ROM (Jelly Bam). I was successful in flashing but am still facing the same problem. No IMEI and "PHONE"
I flashed it back to official stock ROM and I still see the same. No IMEI and versions as:
PDA: I9003XXKPQ
PHONE: Unknown
CSC: I9003SERKPQ.
NOTE : I Have flashed the Stock ROM finally with ODIN with all the four files by appropriately selecting them.
Is this happening due to software error or is this a hardware problem?
Why the IMEI number is missing?
Please help me.

the data present in your efs folder which includes files like "nav_data.bak" "nv_data.bin" they assign IMEI number to your phone... these files might be missing or corrupted... better try any previous restore to fix this problem

Tried that!

I guess you are correct but the restored file on the sd card is corrupted one, I guess. Because the same problem occurred after restoring the previous backups. Can I get any custom restores online for efs? I don't want any warranty for my mobile, I just need it working. In case if it works on a fake IMEI by flashing a custom EFS it is fine with me.

you are on froyo right?? if yes then you simply flash another stock rom of base froyo or gingerbread through ODIN and this should restore your IMEI

No. Am on gingerbread. I've tried Jelly Bam though. But it is of no use. So I reverted back to gingerbread official ROM.

hmmm... actually stepping up for some custom roms based on CM 9 and above solve the IMEI problem.... I recommend you to first download a stock gingerbread ROM and flash it via ODIN... if it doesnt work then download a CM9 based ROM (4.0.4) wipe data/cache/dalvik/ and flash it via CWM recovery then wipe cache/dalvik... it should work and there is like 30% chance to get your IMEI back

But my main point is how u lost ur IMEI suddenly?? You must have flashed something which lead to missing IMEI.

Will Try this once!

IMEI is lost when you delete/edit efs data or when you flash a firmware ,but the chances of loss of IMEI are during firmware flashing are very slim

How to copy cwm backup to many devices of the same type?

Sorry for don't knowing the correct section for this thread.
I installed a custom rom (CM 10.1, with special settings and software) to an Android phone (Samsung GT-S7710).
Now I have to copy this exact system to about 150 devices of the same type.
Is this possible with an cwm backup??
I've also tried to build a odin flashable *.tar file, but don't successful.
What's the best way to make an image of the entire Android system, with all the settings and data. (if possible also from the internal sdcard)
ps.: I have to do the same with a samsung galaxy tab 2 7.0
Thanks very much in advance!

Make a new nandroid back up after toggling the flight mode and then use the new one to modify all the other devices.

Thanks for your help, but it's still not working. I'm using the cm 10.1 rom by flxo.
I flashed the correct stock rom (like flxo mentioned) and installed the custom rom, but the signal returns not before toggling the flight mode or waiting for about 10 minutes...
Any other ideas?

EFS is the one partition you don't want messed up. It contains the IMEI info for your phone.
First things first: you should try to do a factory reset from the stock recovery you have installed now and see if it boots.
If this fails, then: do you have any NANDROID backups made with CWM recovery? If you do, did you also backup the EFS partition? If you did, try to restore a full NANDROID backup and you should be fine.
If you somehow get your phione to boot up and you can't get a network signal, then it means you EFS partition (and IMEI) is corrupted. If you don't have a backup for that, the only solution is going to a phone service repair shop (at least I don't know of any way to recover that without a backup).
Good luck

No. You'd screw things further. Don't flash backups from other devices. The IMEI is unique for each device.
Did you try the factory reset from the recovery you have now?

I don't know. Try it. I think there was an option for it.
You could also try reflashing stock firmware with Odin. If everything fails, I suggest taking it to the nearest phone service repair shop. Restoring the IMEI is a more complex operation. I think a JTAG is required. Not sure though.
Good luck

I do not have the time unfortunately to go into details. But please search on google: "Odin explanation" or something like that. A good example:
http://donandroid.com/understanding-odin-a-beginners-guide-on-odin-buttons-checkboxes-629
Unfortunately like I said, none of the available options can help you.
And never try to use Re-partition unless you really know what you're doing. That repartitions your internal memory to a different layout (like number of partitions and sizes) and requires a PIT file specific to your device.
In the future, always make full NANDROID backups before flashing anything. This will also backup your EFS partition. There are also applications like this one:
https://play.google.com/store/apps/details?id=ma.wanam.efs
And many more examples which I am sure you can find on XDA in your device specific forum. This way, if your EFS ever becomes corrupted, you can easily restore it to a working condition.
Cheers.

Could we get a proper instruction for flashing this rom? Is this rom the one leaked from vietnam ? and also what would be the procedure to revert back to kitkat 4.2.2(ODIN or CWM Backupfile?)

Odin flash is always works and yes u can go back to 4.4.2 but make sure ur using CWM recovery and make one copy of it before proceeding.

When you restore nandroid it will replace all files from your backup so no meaning to have specifically indian version. It should work like all custom ROMs
When you restoring from nandroid, No root requires
CWM Nandroid restore doesn't restore modem and bootloader (at least on chenglu's what I am using) so provided recovery does so?

How did you do that with the MD5 mismatch errors, I verified every file in the backup and they do match Nandroid.md5, so something is obviously wrong, are you sure about the version of CMW?

Hey Doc.
I tried it with a new bootloader and what did happen is that it was impossible to use ODIN to flash any other

Depends, you can either do a normal flash of your current ROM or you could do a CSE flash that would wipe everything.
Here's a rundown:
1.) Normal Flash - flashes stock stuff on top of whatever is running on your phone at the moment. I did this after I installed MLKernel which, unfortunately broke my WiFi and Camera so I had to flash back to stock. I tried this option first because I didn't want to redownload/install everything. Surely enough, I restored stock kernel and got unrooted, but the WiFi and Camera were still broken.
So if you're looking to just remove root and not lose anything, this is what you'd want to choose. Look for the correct KDZ for the current stock ROM you are on. Flash it wrong, and I can't guarantee anything.
2.) CSE Flash - nothing much to write about. Cleans the entire 16/32GB of your internal. that includes apps, files, pictures, documents or anything really that's stored on internal storage. If you've got Titanium backups in internal, well kiss those goodbye after CSE flash.
