Signal Issues - Captivate Q&A, Help & Troubleshooting

Hi, I am new to xda and i'm also quite new to the flashing process. I have a captivate i896 and successfully flashed a rom on to my phone. However after doing so the phone is unable to connect to my mobile carrier. I have also tried to install a modem from the stickied thread how ever it gives me an error::
cwm 3.0.zip error
i'm going to try to flash the helly bean rom in hopes of getting that fixed.
also in the about phone section it says baseband is unknown... ive googled that and it said my IMEI is corrupted or something or other.

It sounds like your /efs folder is messed up. There's a thread in the Development section that goes through steps on how to restore you /efs and IMEI all on the phone.

I can't seem to find the thread... Would you happen to have a link to it?
also!
I'm very lost right now, still cant seem to install any modems on and i checked in the EFS folder, there isn't anything

Please check first if your IMEI shows up in the about phone and that it is the same as the one on the inside of your device. For modems there are diffrent ones depending on what ROM you have flashed so give us that info please. Lastly if your IMEI is diffrent give this a try http://www.xda-developers.com/andro...s-ii-and-other-samsung-devices-in-nine-steps/, i have not used this my self but might be what you need

IMEI shows up as 'unknown'. I flashed the latest cm10 and used the modem KG3 under I9000.
Also, I'm in Toronto, so I'm running the i896 captivate.
i rooted and installed CWM by following the steps in this link http://forum.xda-developers.com/showthread.php?t=1350266
then after when i installed cm10 the IMEI dispapeared

sorry bump. but i think the problem is that i an unable to install the modem.. if anyone can please guide me to install a modem that would be very nice. ive tried to install it through CWM but it gives me a status 0 error everytime i try

If your IMEI shows unknown in the settings menu then it has nothing to do with whether the modem will flash or not. It means your efs folder was wiped. Now you could in fact be without a modem too but you need to fix the IMEI first.
Now with updating to CM10 theres a good chance it made a backup of this for you. Look on your internal SD card for a folder simply labeled backup. If so look in it and see what it has. Hopefully it will contain another folder labeled efs. If thats the case too then all you need to do is get something like root explorer or ghost commander and copy the contents of that folder into /efs in your system.
That will fix the IMEI issue.
As far as modems go you will only be able to flash these... http://soggycashew.weebly.com/cm7miui--ics-modems.html All the rest will give errors when you try to flash.

[Q] CM9 nightly- Network not available!

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.

Urgent Sim Unlock help?

Hey guys before I had 2.3 and I had used an SGS unlocker off the market store to extract my nv_data.bin, I then used the samsung tool unlock code generator, when I used this I remember it unlocking my phone. I'm now running a custom JB rom and my network isn't working at all and when I search for it, it says "error while searching for network" I tried using the same method as last time to do it, i deleted my old nv_data and its just erroring in the samsung unlock tool. It's not asking for an unlock code or anything either What can I do guys

type *#06# in your phone dialer for IMEI number of your phone, if it start with 000 or missing, read this http://forum.xda-developers.com/showthread.php?t=1857054
to solve it IF this happens after you flashed CM 10
Solution:- Reason is you had Jumped from GB to JB (should be on ICS before JB), so now you need to
1) Download Root Explorer from Play Store and use it to
2) Search you internal SD card for sdcard/backup/efs
3) Copy nv_data.bin, nv_data.bin.md5 and nv.log paste them into /efs in your Phone memory
4) Reboot to get back your original IMEI

you can start from the beginning.. go back to GB 2.36 (use a JVU ROM + Root, upgrade to ICS CM 9 and than to CM10
Solution for i9000 on JB:-Try not to jump from Gingerbread to Jellybean, as all upgrades should be done progressively. meaning you need to be on a GB 2.3.6> than into ICS and finally into JB.

When i finished the install, i rebooted. Now my phone is booting into CWM only and cannot pass that...
hello!! my sgs i9000 is currently rooted with GB rom (2.3.4. surface rom) and semaphore 1.5.
can i flash from internal SDcard straight to some JB rom ? (like hellybean or c-rom mix)
i dont want to use odin at all : it has never flashed my sgs successfully on the first try, it always need 3 or 4 attempts and i'd like to avoid that step as much as possible, cause im on old GB already.
so hellybean installation guide,for the example, says:
- make sure to have gingerbread bootloaders (<- this step should be done since im on a GB rom, correct me if im wrong)
- flash allinone.zip
- reboot recovery
- flash allinone.zip again
- flash gapps
i have a backup of EFS folder and i'll wipe everything, also should i revert filesystems to rfs before flashing, or will ext4 work too? maybe that point is not important because of partitions being changed (i dont know...).i know there are tons of installation guides but i cant browse everything. so if i just do it like that way will it be ok?? sounds too good to be true. what do you think?

2-Yes if you have ClockWorkMod you can install new JB ROM.

4-If you had problems with IMEI check quoted post in my first comment.

In my case I didn't back up anything, yet I found efs folder in sdcard/backup/efs, so check it first and see what you have, and about the ROM version, it doesn't matter, you can flash any stock ROM even if it's region doesn't match yours, but I'm not sure if that can resolve IMEI problem.

Well I didn't go through this before, but I'm sure a lot of members here did and they'll tell you what to do as soon as they see your post, but don't worry since your problem is software related the solution would be relatively easy to apply, you can still flash stock ROM anytime with Odin, but make sure to stop KIES before you do it.

[Q] No Service after Installing Custom ROM

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.

Also no signal as you would guess
Now I cant even downgrade to any roms apart from 4.4.4.
Phoen is rooted and tried 4.1.1. I9305XXALI5_I9305EVRALI5_I9305BVALI5 through Odin and Mobile ODIN
On Mobile odin phone looks like its working then stays on the SAMSUNG Logo for ages and nothing, just stays there
I have a Back up of an efs which I done through Rom Manager but not sure if its corrupted or how to restore it
If someone coud give me a walkthrough :highfive:

Hi,
About IMEI null/null with 4.4.4 firmware, you should search in this Q/A forum, there a lot of threads asking for this issue. Maybe you should get an answer yourself
However, you should try again to do a clean flash of latest official 4.4.4 firmware with ODIN v3.09 by following this GUIDE HERE from @MaHo_66.
AFAIK, it's impossible to downgrade from 4.4.4 because of KNOX bootloader. It has been said many times in this Q/A forum. Maybe it exists somewhere a tricky trick to do it but I'm not aware of this.

In Addition to @FLooDW 's answer:
Try to use Philz 6.48.4 or 6.59.0 as your recovery rather then TWRP or the old CWM (6.0.4.7), especially DON'T use the latest TWRP from their official website, its a broken build and its known to mess up the partitions! That could be your problem if you have done that before...
Any recovery you want to use, download from my RECOVERY/GUIDE thread that FLooDW linked to you, use those they work fine.
PS. before flashing official firmware with ODIN, make sure you have a custom recovery installed, then boot into recovery, wipe system/data/cache/dalvik-cache/internalSD/boot/modem etc. this is to ensure when you have flashed the firmware, there is nothing left from the previous firmware that was installed.
Note: when explaining your issue, try to do that by providing as much as possible info about your actions before and after the problem occured, that way anyone who wants to help can help you the best way possible.

Really helpful addition !
Trying what you guys have mentioned just now, let you know as soon as :good:
What 4.4.4. om do you suggest?
Also the efs I backed up (not sure if its working or not as it was with Rom Manager)
How do I restore, can it be done with root explorer?
Tried the [ROM][i9305][18.10.15]>>>4.4.4<<<[KK][STOCK][TW][STABLE][+AROMA] S5 Elite Lite v4.0
which I posted a few days ago, left a post with no reply and thats when I started getting the null/null
PSN_AGNi_pureSTOCK-v5.9.5-4.4.x_I9305_AROMA
Currently trying this rom.. watching the installation set up and says so far that set_perm: some changes failed
used philz_touch_6.59.0-i9305
Rebooting and stays on Samsung Galaxy boot screen ??

AGNi is not a ROM, this is a kernel. Did you flash AGNi kernel over official Samsung firmware ?
As MaHo_66 said, you have to explain more what you have done and what you need if you want us to help you.
Steps :
reflashed a Stock Rom then Rooted it then added Philz Recovery
Then Tried this rom : I9305XXUFNL1_O2UFOB1_4.4.4_KK.zip
Currently trying various modems to see what this gives me
Failing this will need to try QPTS or EFS Professional again.
* I know how to flash and root roms if you look at my signature along with kernels I am basically telling you what I have tried to get
this null/null away as I think its a baseband/modem issue somewhere as I have read various posts and some people agree.
Cant even do the *#197328640# or *#*#197328640#*#* to get into certain modes
Thinking it maybe the sim card slot now .......... I am losing my mind now!

There are few other possible solutions you could try:
- try this, it shows you how to get in service mode and the restoring of the golden efs backup, that should be present if its good.
If above doesnt work, then try the one below.
- have you tried to flash the param_bin file? if not try that with ODIN, it might work.. file attached.
Let us know how it goes.
H yes tied that file and didnt work
will the imei work from another phone or efs?
isnt that link just gps?
