Been trying to flash Cyanogenmod and I hit the wall with a IMIE number that becomes all zeros. I've tried going back to 4.2 and also tried not flashing the baseband. But I can't flash back or install Cyanogenmod without loosing mobile connection.
I'm running generic EU c6833 LTE. Any pointers?
Have a read of this thread http://forum.xda-developers.com/showthread.php?t=2575359, but I think the gist of it is to downgrade to an earlier ftf (.532?) and exclude baseband then flash a recovery boot.ing from the rom then flash the rom...
I think that is it, not tried it though.

Hello all,
I have this Vibrant I’m trying to get to run JB 4.1.2 or 4.1.1 I’ve tried 5 ROMS and none of them seem to find a network... When I go back to my Backed up Stock ROM I get network no problem. And yes I’m wiping both letting sit for 10 to 15 before first reboot.
You are either losing baseband, or losing your imei. I don't know why this happens to some people?? It can be fixed but you will have to fix after you flash the JB ROM of your choice. Because I don't know if its baseband alone, I have to assume its your imei. You need to backup your /efs folder. This might already be done. You can check by going to /sdcard/backup/efs, if you have efs folder in backup, you are good. If not you need to use a root file explorer app to copy /efs and put it on your /sdcard.
The efs folder holds important phone/network specific info including imei.
Once you get a JB ROM up and running,
Go to settings>about phone what is your Baseband-????
Check imei as well
If only baseband is missing just flash a modem
If imei is missing you will need to copy and paste the efs backup you created to the root of your phone and reboot. There are some more detailed guides on this.

What do you flash after you odin back to stock? I lose IMEI, APN, &, baseband if I go directly from stock rom to JB.
What works for me is: stock » GB BL (optional) » update.zip » CM7 (vibrantmtd) » CM10 (optional, I only use the kernel to full wipe) » JB.

When was the last time you tried? The issue where going from a non/old Cwm recovery would break your efs was fixed a while back (with the assistance of a user who was kind enough to send me the rundown of why it was not restoring)
Although you may still need to flash again once in a new recovery.

FE, always spreading solid wisdom throughout the Vibrant forum. Really appreciate all you do for our ancient rigs.
As for the IMEI issue, it was from a crack-flashing & Odin session - ie. I was testing out whether I could jump from an Odin .tar straight to Semaphore kernel .tar then to Slim Bean. I should mention that my phone is one of those post-EU (Encryption Unsuccessful) ones, so it wouldn't surprise me if that alone plays a hearty role.
IIRC, I had tried the T959UVJFD, GBBOOT-T959UVJFD, and Bionix-FishmanMod_odin tar's ... but none of those roms would boot up on my phone after the flash. Again, most likely EU related.
I then flashed Eugene_2E_JK2_Froyo.tar (+ 512 pit). IMEI, APN, & Baseband all fine once booted. Then, Odin'd a Semaphore JB 2.4.0sv.tar (CWM 6.0.1.4), wiped, and then flashed Slim Bean 2.7.0 (4.1.2). Once booted, there was no APN or Baseband, and IMEI was now the generic one (004999...).
What eventually worked was Eugene .tar > GB BL's > update.zip (s15274n's CWM 2.5.1.2) > cm-7.2.0-vibrantmtd > CM10 nightly (kernel only to do a full wipe) > Slim Bean 2.7.0.
For some reason if I don't flash cm7.2.0 before jb...My phone is off and then plugged into the charger it will reboot, its not 'stay awake during charging,' its just a fluke on my phone.
No two vibrators are the same...
I approve this message.
I also have one Vibrant that has a very strange issue that it can't keep its bootloader and the only way to fix it was flashing the Eugene odin file. Even with the factory odin and updating to Froyo via Kies. The bootloader retains with cm7, cm10 and aokp, but with any other roms like Paranoid and SlimBean the bootloader gone missing, even if the modem.bin is still in /radio. Not sure why the Eugene odin fixed this issue.

I Odin'd the MJ9 radio some time ago and have been able to flash 4.3 custom ROMS based on that radio with no issues at all. The problem comes when I try ANY 4.4 ROM. The ROM and Gapps flash and install with no issue. However, I don't have data or voice connectivity. I'll go into APN settings and it's blank. I've tried manually entering the values, but the changes won't stick. As a point of reference, I'm running the MJ9 radio with TWRP 2.6.3.0 as my recovery.
Ideas?
Use philz or cwm for flashing the 4.4 roms

Where are you getting the 4.4 roms? Just make sure you are flashing ones for our device i605..
Only other suggestion I can make is making sure mobile network is toggled on..
You shouldn't loose data if you are flashing the proper rom
ROMs are all coming from this very forum. I never occurred to me to check the mobile network, because it's never been an issue with any of the other ROMs I've used.
No matter what whenever I flash CyanogenMod I lost my IMEI. I've tried dozens of times go back to stock rom (IMEI FIXED) and the install CM and it always ****** the IMEI. I've tried first going to CM7 and later to 10.1 but even doing that 7 already has lost IMEI. This is driving me nuts. I've also tried recovering the IMEI from stock but it changes nothing.
I've found what's wrong:
1) I had problems with CWM. Was using a bad version or something like that.
So for anyone who is having trobble with IMEI lost, try the following:
Flash the original phone rom
Use a good CWM to flash the new rom (by good I mean the official one as the CWM list)
Hi guys,
I've ordered a new, unlocked i9300 from eBay, and I had some adventures with it:
I've unpacked it, inserted my SIM, powered it on, and found out that the phone always thinks that I'm roaming. Instead of trying to understand what's going on, I though: "I'll just install CyanogenMod and everything will be good".
I've installed CyanogenMod 10.2 (latest stable build), only to find out that my SIM is not being detected at all. It says that Baseband is unknown, IMEI and related are unknown as well.
After trying lots of stuff, I gave up and decided to return to stock ROM (4.3). While trying to do that, I bricked my phone, and the only thing I could do is enter Odin mode.
After reading dozens of tutorials and trying lots of stuff, I ended up flushing GT-I9300_mx_20120329.pit, and that unbricked my phone.
I successfully flashed Android 4.3. This version detected my SIM, displayed the Baseband/IMEI, but it didn't connect to the cellular network. I could scan for available networks, but when I chose my network manually, it said "Selected network not available ".
I tried to flush alternative modems, but all it did is making things worse. Usually it made the phone behave like with CyanogenMod, i.e. Baseband/IMEI are unknown.
Again, after trying lots of stuff, I tried to flush Android 4.1.2. That made no change until I've stumbled on this thread. Flushing Patched_Modem_I9300XXEMG4.zip made my networking work again, and restored it to behave exactly like it did initially. Again, the phone thinks that I'm roaming all the time, but at least it works.
So currently, I have two issues:
My phone always thinks I'm roaming. Is there a fix for it?
And more important: currently, I cannot install anything other than Android 4.1.2!
Could you please shed some light on the situation? What happens with my phone? Why does it think I'm roaming? Why does the SIM work only with Patched_Modem_I9300XXEMG4? How can I make other ROMs (e.g. CyanogenMod) work?
Thanks, any help is much appreciated!

When the phone gets upgraded from 4.1 to 4.3 your efs changes from efs v1 to efs v2 sometimes this upgrade does not go smoothly (as in your case) so then you need to always use a patched modem from version mg4 onwards (not a normal one) if you flash a rom which changes the baseband to anything less than 4.3 then it will not work.You need to keep on mg4 or later to keep signal and because your efs is not fully upgraded properly you need to always use a patched modem and preferably kernel as well.
I am not sure about the roaming issue but if you try patched modem and patched kernel together that might help.Take a look here for some patched modems and kernels and remember you always need to use them >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << You should also be able to use 4.3 roms as long as you use the patched files above ie baseband and kernel.
In general, It would be great if I could use CyanogenMod 10.2.
Should I proceed in the following order? Flush CM -> flush patched kernel -> flush patched modem.
Which of the patched versions should I choose?
Also, what do these versions change? What functionality was patched in these files? Can I read about it somewhere?
Thanks for the help.

No the kernel will only work for 4.3 roms not CyanogenMod roms but the patched modems will work.You can try flashing CyanogenMod then the patched modem but CyanogenMod does not include a modem so whatever modem you where on when you flashed CyanogenMod you will keep.

I tried installing CyanogenMod, then flushing some of the patched modems you've linked. Unfortunately, nothing changes - Baseband/IMEI are always unknown.

You mean flash not flush.
Also you should be careful to by things like this off ebay, There is a very high chance you brought the phone broken like this but did not notice straight away.
Don't hang around on 4.1.2 as you might get SDS.
Upgrade to 4.3 stock of higher using custom roms with a patched modem of mg4 or higher as stated by tallman43.
Read here for what you or the previous owner has done. Also on stock make sure your csc is correct.
http://forum.xda-developers.com/galaxy-s3/general/ref-imei-efs-stuff-i9300-including-t2393289
If you cannot get it to work you need to take it in for repair. Make sure it works on 4.3 before paying.
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?
