I recently rooted my samsung fascinate and had alot of problems with custom roms so i decided to just go back to stock. At some point i lost my 3g and have not been able to get it back. I have tried *228 and *22899. I also tried a custm modem, eh09. I also tried a factory reset. Is there anythng else i should try. I currently am flashed back to the stock modem as well, as the custom didnt work for me.
Did you reflash your gapps?

the stock eh03 build already has gapps (market,gmail,ect.) preinstalled
call verizon and have them do a dmu reset or activate a old smartphone on your line then swap back.
it didnt work, they said i would have to find another phone
do you think an esn swap would help? from the research i have done on xda and samsung galaxy fourms ive tried everything else except an esn swap or replacing the phone. Is it possible to do an esn swap without another smartphone, or with a smartphone that cant be turned on?inc
im also trying a new kernel right now
kernel change didnt work

if you have odined back to stock and still no data, the do a esn swap, if still nothing then its hardware related.

Hi all, I don't think most Vibrant users worry about it (at least from what I've seen), but do you worry about losing your baseband/EFS partition/IMEI info when flashing?
For those of you who don't know or forgot, basically some flashes can result in a generic IMEI number and you SIM card would no longer be readable under any custom ROM. You would then have to ODIN to stock and stay there forever, as that is the only way your SIM would be readable.
I know this was a problem a while ago when CM7 or MIUI was flashed, but is it even worth worrying about anymore?
Hopefully someone can inform me and others about the issue. Thank you for your time!
I'm not cause I got my efs backed up. Plus AOSP ROMS are no longer tedious to flash..just flash like any other rom. Though odining back to stock is the only way to leave AOSP I don't really care.

Hey laylovj,
So we only have to ODIN to stock if we're going from an AOSP rom to some non-AOSP ROM? (How common are these?)
Also, I remember hearing that if we want to go from Gingerbread (specifically CM7) back to Froyo we'd have to ODIN. Not true?

Yea...there are three for us VIbrant Owners...
You need to Odin back to stock w/ repartition checked if you want to go back to Sammy based roms coming MIUI and any other CM7 based ROMs.
That's great to know, thanks so much for the info laylovj.
Anyone else?
I think i backed up my efs at some point but i dont worry about it too much... at one point, flashing kernels in gb, i lost.my baseband i had 'no imei' according to my phone... i odined to stock and now im back on cm7 texting 24/7 so idk
... itd prob be aa good idea to have a backup

Why worry now? I could understand worrying when we were toying with fire--i.e. early voodoo, etc. But almost all roms now are easily flashed and provided you follow instructions to the tee, you will have no problems.

I couldn't stand it if I lost my IMEI and was stuck on a stock, Touchwiz ROM. That's the only reason I worry.
younix258, I do have a backup of my EFS folder, but I guess ODINing to stock will also fix the problem like it did for you. Good to know.

I lost my IMEI a long time ago while flashing an unlocker or maybe CM7. I have this generic IMEI that has been working every since though with all the ROMs. Even Tmobile can't identified what phone I am using but they haven't shut down my service probably because I am paying $200 a month on 3 lines,.
Hmm, I wonder how often that's the case though.
From http://forum.xda-developers.com/showthread.php?t=859914,
"In case you screwed your IMEI by playing with the nv_data.bin and you are experiencing issues like:
Fake IMEI (usually 004999010640000)
Unable to download apps from the market
Unable to unlock your SIM card using your PIN
Weird apps are downloading automatically from the market
Blinking SIM card icon on the top tray… ETC"
So I'd definitely like to avoid losing my IMEI, even if everything seems to be fine without it.
I really need some help yesterday i flashed cm7 from stock. Eveything was working fine then after I made a phone call my mobile data dropped out. I tried everything I could think of while running the rom but I couldn't get it to work So I used odin to go back to stock, which didn't work. I then tried using heimdall to go back to stock and that didn't work either. If anyone has any advice please give it I'm desperate.
is it bricked? Do you mean that you can't odin back to stock?
no i went all the way back to stock and I still dont' get any service
what baseband version does it show?
baseband is S:i500.04 V.EH03
did you try doing *228 yet? It might just need to be activated. There was a thread last summer about losing data and having to call cust service and have them do some sort of reset on your esn or something.
The modem on my second fascinate went bad, but would at least get 1x data. It just wouldn't get 3G. Verizon swapped it out under warranty. I guess there's a chance that your modem actually died.
i actually can't even make calls.
I have a quick question because I've run into a problem I can't seem to fix.
First, so everyone knows what I'm dealing with:
Phone: i717
Changes: Rooted (Shows super user access), CWM v5.5.0.4, Unlocked (Tested)
Rom: Stock AT&T Rom
Sim Card: Works in a T-mo branded Exhibit II 4G.
I flashed a radio (tried KID, 0331122 from the radio thread in the dev section, and reflashed the original AT&T radio).Even w/ the original radio installed, it cannot seem my T-Mo sim now.
Do I need to flash a new Rom or what? Wipe data to factory reset?
I would rather not change anything w/o asking since flashing radios seems to be a straight forward thing that most ppl have done w/o touching the rom.
Thanks ahead of time.
Mine worked with a rooted stock rom at first it didnt see the sim then i tried searching the network under wireless and networks it took a few minutes but then it came up.

don't forget if you are running an ICS based ROM you need an ICS based Radio/modem.
EDIT: i see you're running the original GB rom so you need the GB radio.
give it a few minutes to find a signal or go to settings/mobile networks/network operators. choose manual. then let it search a few minutes. then select t-mobile.
I find the Blaze 4G radio worked best for me, but depending on your area, your results may differ. try em all.
You guys are insanely fast.
I'm currently on the stock radio & I'm still getting the same message after letting the sim sit in the phone for 9 minutes (yes, I watched the clock, lol):
Insert SIM card to access network services

Where should I go from here?
Edit: Is the answer flashing another rom? Maybe something has become corrupt? I don't see how as I've read & re-read walk thrus for doing this to make sure.
I've done a little more reading. Flashing the beta ICS rom flashes to the old AT&T modem.
Would this be the best bet?
Edit: After looking through the "about" phone...
I'm on 4.0.3
Baseband: Unknown............. that's really bad.
Edit 2:
After reading, I needed to back up the EFS. No where is this stated anywhere, unfortunately. That contains IMEI and everything else.
Edit:
So, after reading MORE, the IMEI number is on a sticker behind the battery, along w/ the S/N.
Huh? Efs? I dont even know what that is nevermind backing it up. Goto clockworkmod and flash the radio.zip and reboot. Thats all there is to it.

If you look up EMEI number related to flashing the radio, there's a lot of hits.
XDA has a thread on it here: http://forum.xda-developers.com/showthread.php?t=1352371
I'm quite shocked it's not mentioned everywhere as this happens to people now and again.
I have my IMEI number, i just don't know how to input it into the phone.
As for flashing the radio, I've flashed 2, then back to the original. To no avail.
Sorry never had anything like that. I would almost odin back to stock and start over. You dont need root for the sim to work on calls and edge with tmobile.

If you're baseband is unknown don't worry just flash a stock at&t modem and it should go back to normal. Your imei is under a different menu in about phone..the status one.
Also its no ones responsibility to tell you that modifying your phone may break it.

I did flash back to the stock AT&T baseband as stated in the original post.
If I go to About Phone, the Baseband Version is unknown.
If I go to Status, the following are listed as
Network: Unknown
Mobile Network: Unknown
Service State: Out of service
Mobile Network State: Disconnected
IMEI: Unknown
IMEI SV: Unknown
I've backed up the EFS that I have no just so it doesn't degrade further. I'll try to flash again and see, but I still think the EFS is borked.
I'll see what I can, but I think I'll the EFS is borked beyond flashing it to normal.
My point about the EFS back up is that most ppl here don't seem to know what it is. It shouldn't be that foreign of a topic since flashing a radio is obviously problematic for some. I've seen other posts concerning no IMEI after flashing radios on forums other than XDA. It's odd that it's not mentioned as a sticky everywhere.
Backing up EFS would solve a lot of head aches from unlocking / radio flashing woes. I'm hoping this info will save a few people a lot of time and money.
After more digging, I came across this thread:
http://forum.xda-developers.com/showthread.php?t=1646326
Synopsis: Basically, he followed the same guide I did. The only difference is that I flashed the radio while using a stock AT&T rom. Once he flashed back to GB (saurom), he gained back his baseband / IMEI.
This is what I cannot figure out:
CWM will see and flash any radio file I push to my note. If I push a stock AT&T rom, it won't see it. If I put the rom in it's own folder, it seems the rom, but states there's no files.
Is CWM corrupted? Why would it only read firmware to flash radios, but not android roms? Should I just go back and install CWM?
I've searched all over & used google, but I can't find a thread discussing this.
Fixed.
This problem has nothing to do with any of the radios corrupting the EFS folder. Albeit, it's always a good idea to back it up.
Flashing back to AT&Ts stock rom (2.3.6 or 4.0.3) never fix the issue. You will always be stuck w/o a radio, at least from what I've seen. Even flashing back to the stock radio fails. I don't know if it changes the EFS, but AT&T's rom does not like it and shows no IMEI & a bogus SN .
I had to go back, flash to saurom and a compatible GB (or beta T-mobile) radio to get te work fine. ICS radios work fine on ICS.
Saurom and GB radios dont work in my i 717 trying to connect to wind. I got a CM 9 ICS build and ive tired a bunch of radios. they all failed. i keep getting no sim errors. I can see the operator but when i select it it times out and says it cannot connect to the network at this time. it also says interset sim. Im positive it is unlocked.
Modems(radios) or basebands should have nothing to do with whatever rom you are running. Whether they are GB, ICS, or JB modems, they should all work to a degree, at least for phone call ability. I have flashed many different radios trying to get the best function of my att note on t-mo. The best I got was using the Blaze modem. That got me 3g hspa.
The worst will be just giving you edge speed. My note is unlocked and has been on JB running blaze ICS modem working fine. Maybe you need to start over, evaluate what you have, and go from there. There are great threads on att over t-mobile. Good luck.
I picked my rom, and started flashing 5 or 6 radios, and found what one worked best on t-mo.
Presently, I have switched back to att- sort of- straight talk. I'm not thrilled with the speeds. No higher than 4 mbps DL, and 1-1.5 UL. Thinking about going back to t-mo and dealing with the slow UL speeds. I'm on an ICS rom with the ucle6 modem.
Also, flashing a rom does not change your modem. You have to physically reflash the modem you want. Some modems show up as unknown under the baseband. Blaze is one of them.
Another thought- sometimes a reboot will get your sim recognized by your phone.

This is yet another case of the "no sim" bug ....
Damn I wish we could find the answer to this issue, but none exist .....and for some users the return to complete stock even fails to recover service ..

Really what an incredible unlucky glitch.I got my note for only 360CDN good condition but missing the stylus, even still it was a good buy. I'm on Wind mobile, T-mobile here in Canada. I even gave it to somebody who's done a bunch and they ran into the no sim problem. I guess I'll be going back to my HTC HD2 and sell the note .
---------- Post added at 11:48 PM ---------- Previous post was at 11:44 PM ----------
So just to confirm I have followed the process correctly over 20 times and no matter which cm9 cm10 based rom and any ics or gb based radio will allow connection or recognize the sim to the 1700 aws network. With a cm9 based rom I can see my network, but it will not allow connection like the phone is locked, even though i have unlocked and tested the phone on other networks.

Yes, I have the same 'No SIM' issue with a working WIND SIM. I've tried everything, multiple Radios, multiple ROMs. Very strange problem. I wish we had the tools that the SGSIII has for dumping and restoring the NV ram. Even stranger, I do have a the correct IMEI number in Phone, About. I have a feeling it's something to do with how the phones were carrier unlocked.

It has nothing to do with your unlock. If you've followed the steps and are still having no sim issue you may have to get a new 32k sim card from wind the older ones won't connect in a phone with lte

Had to replace the TMo SIM card with a newer one today. Solved the problem of "No SIM".
I know this is old
I have the same problem with "NO SIM." One day i flashed so many things to my phone and one time i turned it on i got ATT on the top right corner and everything was good. I made some phone calls and texts and even browsed the web. I restarted the phone to check if it was just a fluke and it was. Ever since then i cannot get it to read my phone, but i know for sure the hardware works.
ive been having same issue Network not availiable and also where i normally have 4g service i know only get 3g.Ive flashed several different roms still same issue.Could this be glitch in vzw AWS system?Is there any other radios we can flash? I notice that it take a really long time to do network hand offs too. Like I am talking a few minutes to switch from 4g to 3g or 3g to 4g. Signal bars show full, but there is not data and then they go gray and then it takes a few mins and they go blue.
basically im having the same issue as post #2 in this thread.

I also notice that under access points, i dont have anything listed and when trying to add an apn, and hit save, nothing happened
Anyone have any issue similar. I found some threads but they were not any help
Try getting a new SimCard. Those can sometimes go bad when being transferred from phone to phone. They are free anyways too.
im going to try that a little later today. thanks

Possibly. Something could have been corrupted in the process. If it still does it on stock go to Verizon and complain.
i flashed back to stock and my download speed is 800 and upload is 85. it shows I have a 4g signal and the system status shows that my signal is -102 or -98.
anyone else have any ideas?
So things ive tried:
1. new sim.
2. back to stock touchwiz through odin
3. flash stock modem through odin and stock kernel
4. doing the whole process to root and stuff manually, then installed a customer recovery manually and then flashed a new rom, still no results
are we going to call this hardware failure? or is there any other reset type thing i can do

thx man, i hope someone knows how can i solve the problem.
What had you done before you got to this issue of no cellular signal?
Did you flash a custom ROM etc..? Which version were you on before? 4.3?
What did you do after you found out about this issue? Did you by any chance flash an older version?
Because that tends to do that, atleast that's what happened to me.
I had a wrong/fake IMEI ("0049..."), which caused that I had no cell reception and couldn't use the phone to call or send/receive sms etc...
I googled a lot and I tried some of the TUT on the web, but nothing helped. Until I found a thread on the xda that said one could try to flash a newer stock ROM (don't know the exact thread).
So I went ahead and checked the version I was on...luckily it was 4.0.4
I then downloaded a newer stock ROM 4.3 for my region and flashed that using ODIN...once it passed I went to recovery: wiped cache and factory reset.
and voila...when I checked the IMEI code again, it was back to the original one.
If that doesn't help check the following thread on xda: here
I suspect he allowed the battery to run out, which corrupted the efs partition, as he says his phone was on 4.3 and didn't change anything until after the problem happened.
Flashing latest stock firmware is the first step, as suggested above, but I think the OP may have to pay for a repair. Make sure it works on 4.3 before you accept the bill.
I forgot to say, my battery got bigger before that happened, i can't fit it in my phone, is double than a normal one, i buy other battery, have this something to deal with the problem?

That's not good...bulging/expanding battery is a very bad thing and should be replaced asap.
Why it happens, is another thing...could be due to various reason such as thermal runaway or even acid leakage.
Fix that first before you move to any flashing and/or other stuff...

Hi everybody, i finally sent the phone to service and they fixed it for 17€; everything ok, no problem occurred...i flashed stock 4.3 ROM, then CWM and SU, but....then....after one day of use, i forgot to shut down the phone and, again, removed the battery with the screen on....i connected quickly the battery and the phone started without press any button.....and then, surprise!!! Me trying to make a phone call: "Not registered to network"...fu**...but IMEI was still alright(w t f?). Third day i sent again the phone to the service and they told me that i am playing whit the soft (what man? just because i flashed CWM and SU? damn), i told them again what i do with the battery and they said is not true (now what i am supposed to do? they don't trust me) but fixed it again free..for first and last time. Now here is the question: what i need to back up in case that will happen again? It can't be fixed with a backup of IMEI/Modem file...
Go read the sticky thread in general forum.
