Greetings!
I apologize if there has been a similar thread, but I couldn't find anything that worked, so here I go:
I flashed to the official XWJW1 firmware (which I got from here: http://forum.xda-developers.com/showthread.php?t=1102881) successfully, I then proceeded to root it by flashing Semaphore 2.7.4, again successfully. I then booted into CWM recovery and flashed Slim-I9000-4.2.2.build.3-OFFICIAL.zip. The first time, the phone rebooted almost immediately and got stuck at the boot screen, which I assume was because it installed the new Semaphore kernel only, so I removed the battery, went back into recovery mode (this time it was indeed the new version of CWM) and reflashed the ROM successfully. I installed Slim_Gapps.4.2.2.build.8.zip as well and booted into SlimBean. All is working great apart from the "minor" problem of no mobile network. I went in the settings > mobile networks > network operators and got "Error while searching for networks". I went to check the information under About Phone and saw this:
Baseband version unknown
I read it could be due to messed up /efs folder, so I reflashed the official XWJW1 rom (with working network and correct baseband version), rooted it and copied the /efs folder (using ES File Explorer and Superuser). I installed the SlimBean rom again (still no network and no baseband version info) and tried replacing the /efs folder: first with the AROMA file manager from within the recovery mode, then with ES file manager, then with Android Terminal Emulator - NONE worked. I tried deleting the entire folder and then copying the backed up one, I can't delete it (even though I have superuser permissions). For example ES FM gives "error code 39" when trying to delete the folder and it either deletes all files from inside (apart from Lost+Found folder) or only some of the files. Same with AROMA. I checked that /efs is mounted rw... (I'm not even sure if I should try to alter it while it's mounted and the phone is running, but this was one of the ways I read about while searching. When I enter CWM recovery, it does not appear to be mounted and thus is empty.. so I assume whatever I paste in there will get wiped once it's mounted at boot)
Any idea how to restore the folder from the stock firmware or how to get a working mobile network?
Model number: GT-I9000

Try flashing "stepwise", ie.
2.3.6 ->CM9 -> Slim Bean.
This ensures that your IMEI is kept. When you flash CM9, let it boot completely first, then reboot into recovery and flash Slim.

Thank you! That indeed worked! One question: when I installed CM9 the firmware changed to XXJVT (and this is now the one shown under baseband version in SlimBean). Is there any major difference between XWJW1 and XXJVT, does it matter at all?
Modems do differ, mostly in terms of region (most modems are localised for certain countries). The differences between XXJVT and XWJW1 I have no idea about.
For most people it doesn't really matter, XXJVT is fine for them. Changing modems is only really something that you do either to save battery (some modems are better at battery than others), change for region (say XXJVT doesn't work too well in your region) or just to test other modems.

I'm having a similar issue now too. Going from jw6 to cm10.2 and lost my imei. Tried the advice above. jw6 - cm9.1 (imei fine) - cm10.1.2 and get the imei missing message. Maybe I'm gonna just have to stick with cm9. In the end it's just a backup phone for my kids but I want nova on it.

Hmmm.
Try
JW6 -> CM9 (If your IMEI was fine, then I don't really see why there's a problem...)
Then CM9 -> CM10 or CM10.1.0 (as another intermediate step, to see if your IMEI survives)
If your IMEI is fine, then flash 10.1.2
Odd though, the only time I've had IMEI loss going from CM9 to Jelly Bean was because I didn't let CM9 boot up properly first... So try to flash CM10.1.2 straight from CM9 and see if you run into the same problem again

Upgraded my SGS stock 2.3.3 yesterday to CM9 nightly posted on 07-06-2012. I love the ROM, but the only problem is - i don't have any network signal on my phone. Wifi works. It seems to scan the mobile networks and registers also and creates APN connections automatically. But on selecting any of the networks, it shows the message: "unable to connect to this network at this time. Please try again later." The IMEI number shows up correctly. Using Vodafone India network.
I feel it should be just a minor setting somewhere that is missing...
Does anyone know how to make this work?
...or should i switch back to the stock ROM, and maybe later to CM7? I'm on Linux. Found XXJVU ROM in Heimdall format. Do i need to install clockwork again after installing XXJVU?
Thanks in advance.
Wipe again.Flash again.
hey! make a copy from the zip file of the ROM and replace the file (apns-conf.xml) which is uploaded here as a zip file with the file (apns-conf.xml) in this directory "System/etc". it worked for me and i wish it will work for u bro.
send me if it work with u or not.
Why you don´t install de modem from the your ROM stock 2.3.3 ( via Odin ) ?
I think the new modem ICS is not compatible with the system of their country.
Tell me how you solved your problem.
Sorry, for my poor English.

Before upgrading I had taken the back up of EFS Pro application, after upgrading since EFS Pro was not detecting my mobile. I had installed root explorer on my mobile and copied the EFS data into /efs folder but it did not helped.
Ok, so this is the story so far:
I purchased the phone
Rooted the phone
< some weeks/months pass >
Installed BMA6 for I9305 (not N, radio not working) (at this point I had sboot for I9305)
Installed radio for I9305N (radio not working)
Tried CM10.1 (radio not working)
Restored my stock ROM with cleared data partition: XXALIA system with COVALI7 CSC and XXALI8 modem (radio not working)
Restored nandroid of XXALIA... see above (radio working)
Installed I9305NXXBMA2_I9305NNEEBMA2_NEE (sboot for I9305N now) (radio not working)
Restored my stock ROM with cleared data partition: XXALIA system with COVALI7 CSC and XXALI8 modem (didn't try booting)
Restored nandroid of XXALIA... see above (radio working)
Installed XXBLL1 modem on top of nandroid (radio still works)
So it seems that the radio is only working when I am at literally the stock software that shipped with my phone. I have no idea what's going on.
I am open to pretty much any suggestions here, please help me!
UPDATE: Discovered that installing Perseus kernel on Samsung roms fixes the problem. Still need to figure out why...
I'll add that when the modem doesn't work, I cannot get the IMEI number at all.
You must be going wrong somewhere. Do a complete system restore (emergency firmware restore on Kies if you have to) flash CWM or TWP recovery, then just wipe both caches, data, system, install CM or LS, wipe data then boot.
If you go through that whole process exactly like that and your radio still doesn't work then I will be amazed as both CM and LS don't flash your modem

Both current AOSP ROMs (Liquid Smooth & Cyanogenmod) currently have kernels based off Perseus so you should be fine running them.

I am not.
Sorry, don't know why it specifically only works on Perseus, but I use quite different sources to the official Samsung ones so there might be something different in the modem APIs which makes it work.
Right, I've had enough of this, sending it to service center tomorrow... stockified of course.
EDIT: Change of plans, system status in bootloader won't reset to stock so I am back to Perseus kernel... guess I'm gonna have to actually figure this out after all...
Hi,
I'm pretty new to the whole custom ROM scene and have come across a problem when installing CynogenMod version 10.1.3-RC2-galaxysmtd. I've been able to get everything else working but can't seem to get any network service or GPS.
I've read numerous articles on flashing a correct radio or installing a new modem (not sure if this is the same thing or not?) if you can't get any service but haven't done this yet. I've also read articles on moving the files from sdcard\backup\efs into the efs folder in the phone memory which I've tried but doesn't seem to work either.
My baseband version is I9000XXJVT and the rom is running on android 4.2.2. Before the ROM I'm currently on I came from a stock Gingerbread ROM. Was there something I needed to do when coming from a stock ROM that I missed?
Any help on this would be appreciated as I've hit a bit of brick wall
Thanks
Hey there,
So long story short, you've probably lost your IMEI. You can check this by going into Settings -> About Phone -> Status then scrolling down to IMEI. If it begins with 044 or something similar then you know you've lost it.
So to solve this:
1. Flash back to the stock Gingerbread you were on by means of Odin, there are many guides for this but the one http://forum.xda-developers.com/showthread.php?t=2444308 is quite comprehensive (and leave the OP a thanks as well)
2. Download CM9 from the Cyanogenmod website.
3 Root your S again (this will depend on which Gingerbread rom you flash).
4. Boot into CWM recovery. Do the usual data/cache/Dalvik wipes.
5. Install CM9. Let it boot. You don't need to download ICS gapps for CM9 as all you need it to do is boot.
The reason why you install CM9 is to make sure that the IMEI sticks when you then flash a JB rom. Flashing straight to JB from GB tends to lose the IMEI as said before.
6. Once you've let it boot, reboot into recovery again. You don't really need to do the same three wipes again. Install CM10.1.3 RC2. You'll need to flash the zip a few times- three times at least. Flash Gapps as well, of course.
That should hopefully make your signal reception and GPS work
(I covered this quite briefly so if you do need clarification on any of the steps don't hesitate to ask)

Hi
I checked and I do have an IMEI number which begins with 3 not 0. I also checked the IMEI number and it brought back the correct phone details.
Should I still follow the guid you have linked to or do I not need to do that?
Thanks.
Odd... If the IMEI is intact then you should be geting reception. What you could do is make a backup of your rom and then try the steps I suggested to see if you get the same problem.
Most likely however its due to your modem. In the development thread there's a list of modems compatible with the I9000. Try flash XXJW4 or one for your country through recovery and see if that fixes anything- if not, try the steps.

First, i'd like to thank our atrix hd wise guys for all the knowledge you've put on this forum .
Now to the issue at hand, i'm currently running CM10.2 nightly 05 oct. I've been having modem crashes for weeks now as described in this post:
http://forum.xda-developers.com/showthread.php?t=2385048&page=24
Weird thing is, i only get these crashes when in the area where i work. Back at home i get no modem crashes at all.
My Baseband is MB886_BP_100740.071.65.04P
I'm considering flashing mexico retail modem (which has good user opinions) using the procedure described in this thread:
http://forum.xda-developers.com/showthread.php?t=2233871
I've figured the backup process for the modem should be something like this:
Code:
dd if=/dev/block/mmcblk0p1 of=/storage/sdcard1/modem.bin bs=4096
So, now with the questions:
1. Before proceeding, i'd like to know if this would be a correct backup procedure for my current modem files?
2. Would i be able to restore this newly created modem.bin file with fastboot in case mexican modem doesn't work/solve my problem?
3. From what i've researched, the mexican 4.1.2 modem file should be compatible with CM10.2 JB 4.3, am I correct?
Thanks in advance for any help on this!
From my experience with other phones, modems work regardless of android version. If that backup procedure is correct (which I have no clue if it is), you can restore it by reversing the command.

I went ahead and backed up / flashed a new modem, so to answer my own questions.
1. The backup method for the modem partition was correct.
2. I was able to restore the backup i created.
3. A 4.1.2 modem worked fine on 4.3. I believe tho there could be incompatiblity between ICS and JB for example.
Sadly i haven't been able to solve my modem crash issues, i will report if i find anything. Thanks to the previous user for the input above.

Hi
I mistakenly formatted m7y modem via CWM two days back. How can I restore it, seeing that your process was successful?
Thanks in advance.
I have a SGS Captivate I have been using as a sports tracking device and as a music player for the past year. I now have a few questions before changing ROMs on it.
History >> Two years ago I soft bricked it while on CM9. Not being able to resurrect it at the time I purchased an SGS3 and set the Captivate aside for a while. I resurrected it using a KK4 Heimdall One-Click and immediately flashed it to CM10.1. Having been on CM10.1 for a number of months I upgraded the device to CM10.2. After doing so I noticed the bootloader was listed as unknown and the baseband was KG3. I have checked this in terminal emulator and using a "Samsung Info" app from the PlayStore. I've verified the KG3 modem is for the i9000. I checked in the updater-script of the CM10.2 I downloaded and installed and observed it being coded for captivate and for i897. So, I am not fearful that I downloaded the incorrect ROM.
I have known of the above discrepencies for months and have not been terribly concerned. I do not know if they could have something to do with the fact that I have not had a sim card in the phone since before I resurrected it. Even though I do not currently plan to use it as a phone I intend to have it in a condition to do so if needed. That, and I was interested in flashing a ROM I have seen recommended several times by @BWolf56, Gamerzrom Legend 4.0. The questions I have stem from the fact that I will be going from a ROM based on Android 4.3 to one based on 4.2.2.
To correct the bootloader and modem I intend to flash, again the KK4 stock ROM (Gingerbread). This will be with the Heimdall One-Click from the forums, Odin is not an option - I run Linux. Once installed I will verify bootloader and modem. Based on the Gamerzrom blog I will then install CM10.1 before installing their ROM. (This could be avoided if I were not going back to stock.) At each step I will wipe and format as indicated, I will probably wipe and format to excess.
[Q1] Is this the best approach to get to having the 4.2.2 based Gamerzrom installed from where I am?
[Q2] Should I not do this at all, the donwgrade, even to stock, could seriously damage my phone?
[Q1] Is there anyone who thinks I could safely shortcut the above by simply flashing the KK4 bootloader and modem?
(If I can still find a download on the forums.) This would eliminate going back to stock GB and then to CM10.1.
[Q2] Is there no reason to worry about the bootloader and modem? The discrepency is simply an artifact based on there being no sim card in the phone and I would be best off advancing directly to flashing Gamerzrom from CM10.2.1.

1: don't need to flash cm first but you do have to flash the ROM twice to repartition it then flash the gapps.
2: flashing stock should recover/fix your unknown bootloader issue but unless your imei is unknown, you shouldn't have any problem using as a phone if needed.
I do suggest flashing KK4 before going to GamerzROM to avoid any issues.

The imei is still present at least according to "Samsung Info" and using getprop in terminal emulator.
Okay, flash stock KK4 rom, no need to flash CM10.1, but flash Gamerzrom 4.0 twice.
I was getting CM10.1 from Gamerzrom 3.0 installation instructions for those coming from GB. I was thinking going back to KK4 would reset the partition scheme to GB. I guess the double flash of GLE4.0 takes care of the repartitioning back to JB layout.
Thank you.

That's exactly it, whether you flash cm or gamerz twice, it will do the same thing and repartition. Just don't forget the gapps after.

While it's an old device, it's really great and some of us keep supporting it
Mixed Results with increased understanding
Well I went through the process I outlined above, or tried to do so.
I downloaded a One-Click stock rom, android 2.3.5, from this thread. It is actually the same leaked stock rom I used two years ago. I flashed it twice per instructions to get the bootloader, doing so to correct my unknown bootloader issue. After this was installed I used a "Samsung Info" app to verify bootloader and modem. The modem was KK4, yet the bootloader was still unknown. I repeated the process twice more with the same results.
Rather than download a different stock GB rom I proceeded with the remainder of my plan. I flashed Gamerzrom Legend Edition 4.0 from here on the recommendation of @BWolf56. I wiped, formatted, and then flashed twice as he recommended. The ROM didn't boot, but not to worry I repeated the process. Still no boot. I next went ahead and flashed CM 10.1.3 and booted into it. The bootloader was still unknown and the modem was now listed as KG3, an i9000 modem, again. My guess is CM did this since this how it was listed before I went back to stock. I now went back to Gamerzrom and successfully flashed it. (Still showing bootloader unknown and modem as KG3.)
I am setting up the phone this evening. So far in addition to installing ROMs and adjusting settings I have verified wifi works. Later tonight I will be testing the GPS and bluetooth. With the "wrong" modem my results could be decremated, but I don't expect them to be. When I was previously on CM 10.1.3 and 10.2.1 and on the KG3 modem all worked. Bluetooth, wifi, and GPS worked that is, I didn't try calls because I wasn't using it as a phone and didn't have an appropriate sized sim to borrow.
If I need this device as a phone I will first try it as is with bootloader unknown and modem as KG3. If that doesn't work I will flash an i897 modem, probably the KK1 modem, and see how that works. If that doesn't do the trick I will try an earlier GB stock One-Click rom, either KK1 or KJ3.

Bluetooth, wifi, and GPS worked that is, I didn't try calls because I wasn't using it as a phone and didn't have an appropriate sized sim to borrow.
If I need this device as a phone I will first try it as is with bootloader unknown and modem as KG3. If that doesn't work I will flash an i897 modem, probably the KK1 modem, and see how that works. If that doesn't do the trick I will try an earlier GB stock One-Click rom, either KK1 or KJ3.

Modem doesn't affect BT so it should be fine. It's odd that Gamerz didn't boot but glad it turned out fine. Also, having a different modem won't change anything about the bootloaders but that being said, I highly doubt it would stop you from using it as a phone.
You're seeing I9000 modems cause the ROMs were often built off the international version of the Captivate. Both I897 and I9000 work well on the device and you can flash whichever one gives you the best results in terms of networking (which you don't seem to be using anyway).

True, the kernel controls BT and wifi. I'm not sure why I was mentioning BT w/ modem.
I think I didn't organize my thoughts too well in that last paragraph. Closer to what I meant was that if needed as a phone I would try it as is >> unknown bootloader and KG3 modem. If I had any troubles with it working I would try a different modem. This is where I was erroneously thinking that the i9000 modem may turn be a problem. If that didn't fix it then I would go with another stock ROM to give another go at fixing the bootloader issue. I actually think/hope it would work as it currently is. The phone has repeatedly booted, so at least the sbl (?) secondary boot loader partition is intact.
BTW, the GPS seems to be working well, even though I have a 10/08 build device. Bluetooth, on the other hand, is not pairing with my Linux laptop nor a cheap bluetooth speaker. The same held true when I was on CM 10.2.1 with the cappy. Both, the laptop and speaker, pair with my SGS3.
Could the reason the Gamerzrom didn't flash straight off is that I was coming from a stock TouchWiz 2.3.5 rom instead of from any JB rom? Thank you for helping.

BT not working can be cause it wasn't updated in so long or kernel issue. Or could simply be that it doesn't work with your specific devices.
I flashed mine off stock KK4 (same one you flashed), tried to boot without flashing it twice, which of course didn't work but then went back in recovery, re-flashed and it booted just fine.
