[Q] Unknown Baseband???

been searching for 10+ hours and no luck or solution.
i was on gummycharged ep1f/ep1h rom and everything was working fine until today.
i don't know what triggered it, but my phone just restarted and then lost all signal.
after searching and looking at phone info, i found first line under baseband version shows "unknown".
tried flashing to every possible roms out there using odin and it would not bring the phone back to life.
funny thing is i have no problem w/ 4glte service, which allows me to surf and download but no voice service.....
do i have no choice but to go to verizon for replacement phone?
thank you.

yeah I'd take it into them, sounds like some hardware got fried.. however I'd probably try to flash a froyo rom for whatever good it'd do, if they somehow can check baseband and it shows GB your warranty is void and they will not fix or replace it
blazing through on my VZ Droid Charge 4G

found this over in the Galaxy s 9000 forum (wc8 posted it)
Mine now works fine
so what was the cause - still no idea
so what did help - rebooting the phone couple of times without the sim inside
heads up !
worth a try and not my fault if something blows up...
Begin minor rant:
Isnt it sad that we (everyone including devs and XDA as well as casual helpers like me) have to put that final line in there so they dont get blamed/flamed if things get f'd up?

Had the same problem with my Fascinate. After a flash I lost all 3G and phone capabilities. What I did was reset my phone line with the esn of an old phone I had lying around. Go to this thread. It will show you what you need to do.http://forum.xda-developers.com/showthread.php?t=1051543. I took mine to Verizon, and also spent hours with tech support and, to no avail. This esn swap did the trick. Good luck.

did the stuff you were flashing include the radios? like this one?

or this thread?

yes, all the roms i flashed had full radio from ED1, ED2, EE4, EP1F
none worked....
i'll try to search and see if esn method works that someone mentioned above.
keeping my fingers crossed....
currently, phone is @ stock ee4 unrooted w/ no baseband for cdma radio.

if anyone else is having same problem, do not run esn swap!!!
it will cancel your unlimited data and there is no way to bring it back.
thank god i read it before i tried it....
phone still no go with unknown baseband.....
HELP?!?!? PLEASE?

i called Verizon and had them do it over the phone. In other words, they moved my line to a dummy ESN on their end and some random number to my phone and then switched it right back, all while my phone was off, so when my phone was turned back on it got re provisioned on their network, which fixed my 3G data issues......but i dont think this is the OP's solution. When i had that problem I had phone service, just intermittent or no 3g data is all

You won't lose your unlimited data unless you switch to an ESN that is not a smartphone. I have switched my line a couple times and still have unlimited.

well if you are stock ee4 unrooted I think you are golden. Take your phone to verizon and have them deal with it.

I am not sure abotu this (not saying it is wrong but I never tried) I say take the 20 minutes on the phone with VZW and let them do it...

UPDATE
took it to verizon store twice, got sim cards replaced twice at two different locations.
still no go, rep recommended me to contact replacement center.
talk to tech for and hour trying to figure it out,
the tech announced that my cdma radio is fried.....
so i asked when i'll get the replacement and he said sometime on tuesday.
and i asked if i could use my really old LG non-smart phone for time being and he said i'll loose my unlimited data and moved to 2gb tiered data plan...
so i guess i'll be out of service until tuesday....

Hey I believe ya, I am just in the better safe than sorry frame of mind when it comes to the unlimited data structure. It does make sense though since i did switch from the fascinate to the charge without losing it

they told me this will only work if you went from smart phone to another smart phone.
however, if you went to non smart phone and then smart phone, you'd lose your unlimited plan.

I'm surprised this couldn't be fixed with a software flash. I came from a Samsung Epic and this was a regular occurrence on at least one of the Gingerbread leaks. Happened to me at least once - used ODIN and reflashed the whole shebang (full TAR with modem) and got it back up and running.

i wish there was an easy fix like you said.
then i don't have to wait for them to send me replacement device and also saves me from hassle of reapplying invisible shield. the maximum protection kit is pain in the ass to apply.
i've flashed with every single rom+radio out there in many different order with both odin 1.3/1.7/1.8 and samsung pstlite.
i've also tried flashing radio only and still no luck.

"No sim" issue on Skyrocket

I've been using NexusMod on my Skyrocket for a few weeks now, and all of a sudden while walking around in the mall today, my phone said "no sim" while it was low on battery.
I couldnt' do anything about it, but by the time I've gotten home, I've looked up everything about a "No sim" issue, and tried the following:
reflash to Buoyancy 1.3.1 (GB) via restore
flash to different radios, then back to UCLA, then to Rogers, then to Telus, back to Rogers, and every other combination
restore to stock via Odin
after restoring to stock, reflash the original K7 radio (when it didn't work)
more various flashing of roms and modems
Ultimately, nothing has worked. I've tried putting a piece of paper to force better contacts, and obviously switching sim cards which didn't help.
I've noticed some other people had this issue, but it looks like flashing the T-mobile modem worked, but didn't work for me. Any other tips or experiences?
Thanks in advance!

You try giving the carrier a call to reset the signal?
Sent from my I727

Called up Rogers, they asked me if the SIM worked in another phone (which it does because I'm using my SIM in my old HTC to call) and they said it's not an issue on their end. Not to mention they weren't too eager to help fixing a phone I didn't buy from them.
Anyways, it's been brought back to stock now, using the sammobile (also tried the XDA tar) and neither fix the issue so it's probably a hardware problem unless someone can suggest otherwise.
I've tried the Blaze, Tmobile, Telus, Rogers, and various AT&T (UCLAx, UCLDx) modems to no avail against a combination of ROMs.
Oddly though, occasionally on certain radios, I noticed it would show a reception bar, but also say no sim at the same time. It doesn't happen in stock GB, as it only says no sim and then a "x" on the reception bars.
I'm sure it's a one-off issue, but can't say I'm impressed with Sammy right now given I've had the phone for only 4 months and it's never been abused.

It does sound like a hardware issue but for future reference for when you call rogers:
Don't tell them you didn't buy the phone from them.
When you ask them for help, say x isn't working so can you do y. They will say have you tried this, this and that, say yes and get what you want.
This is the only way I have survived rogers since inception (long time customer helps too I guess).
Sent from my I727

This may sound crazy to you but from many years of experience with electronics and in IT I would say that since it sounds like a component failure or loose contact I would say try gently tapping it with the battery out and reboot. If under warranty tap a bit harder
Just my opinion please no comments if you disagree...

Turns out the sim card tray was loose. Samsung wouldn't fix it saying this is not a warranty item and wanted to charge $120 to fix it or $35 just to return it to me.
Luckily, after complaining, rogers graciously footed the bill since the phone is less than a year old, though the Hup period got extended 6 months (but not my contract)
Kudos to rogers but shame on Samsung for not taking care of its customers. Aside from day to day use, the phone was never abused nor was there any external physical damage. Not sure how they reached that conclusion. Sure it might have slipped out a pocket or what not over the few months I used it, but it should be able to withstand abuse from daily use. my old HTC Evo 3d withstood a hell of a lot more damage than that, I dropped it down a flight of concrete stairs that dented the entire side of the phone. it worked perfectly fine until I lost it. I am sure I will get a lot of heat from the Samsung fans here but I can't help but vent my frustrations.
To think I supported Samsung by buying a GS2 for my wife and I...

Still have sim error after update who else?

Yeah just another update thread. Who here is still getting the no sim error after installing the update it is now worse for me! I am more of a reader and not a poster im just curious is there a work around for this like for example has anyone installed a rom and the problem went away?
LIttle Rant: I have had nothing but motorola smartphones Droid X, Droid Bionic, Razr Maxx so I got curious since the S3 is one of the top selling phones to check it out and let me tell you love the phone but getting that stupid error all the time is annoying I picked my s3 up thinking I could make a quick sell on my razr maxx but now im stuck switching back and forth between the S3 and the razr maxx Verizon even sent me a replacement did that help? nope now its been 3 days they have a ticket open so who knows any help would be apprectiated and lets hear your story!

I'm still getting it, even worse than before I installed the new modem (radio). It seems to be more prevalent in areas where it's switching from 4g to 3g and back. If I'm in an area that has a strong 3g or 4g signal, it never gives me that problem. Has to be a Verizon thing or something with the SG3 that can't handle the switching between the two modes, just not sure......

UPDATE: I can confirm that if I place myself in a particular position in town where my phone will constantly switch between 3g and 4g and I attempt to send SMS messages my phone inevitably drops all data signal and gives me the no sim and no connectivity message.

I haven't been to were I used to get them bad....but I got one in an area yesterday where I generally get a strong 4G single that I had never had the no SIM issue before.
I was not happy.
galaxy. s3. synergy. yadda yadda.

I am getting it all the time at my house sometimes to the point where the phone does not work at all but if I drive down the road phone works flawless no errors even at work no errors im starting to think it might not be the phone it could be there network but for the hell of it lastnight I switched back from my razr maxx at home and the phone worked fine and when I woke up phone was fine im wondering if this only happens when the network is more at peak operation im growing very frustrated with this phone might off it and just use the razr maxx or hope for another update.

I had the same situation just moving from one room to another in my house. Yesterday evening I received a text from my neighbor asking if I had noticed we were receiving a 4g signal in our area (we are in a rural area about 12 miles outside of Tallahassee, FL.). Since yesterday I have a solid 4g in my home area so the no sim problem has disappeared. But there are pockets of weak coverage areas on the way to work in town and at the Florida State University where I work and I continue to find small areas where the problem persists. It has to be the SG3's inability to handle the hand-offs between 3g/4g which produce the no sim problem. My Thunderbolt would handle the switching from 3g/4g much better and not produce the no sim error. I'm sure Samsung could remedy this with a software change (at least not display the no sim) when switching service.

I still have the error on 2 phones. Funny thing is it seems that now it is worse on my wifes phone where it was the other way prior to the update.

From reading this thread and similar threads/topics regarding the sim errors with the GS3, I figured I'd post this here. This is confirmed, my friend and I both have a GS3 bought on the same day at the same VZW store. She keeps getting a sim error while I have never gotten one regardless of coverage or 3G/4G switch frequency, I frequently switch from 4G to 3G when on the subway. She went into the store and requested a new sim card, wound up arguing with the rep, according to him there's no possible way the error could be related, she finally got a new card by calling reps at various levels. After doing a factory reset and reprovisioning the internal SD card with the new sim, she has not yet had a sim error with the newest OTA. So it seems many Verizon sim cards aren't necessarily defective, but are improperly configured with the VZW network. This is just an educated guess based off personal experience, hopefully this is helpful to those with frequent sim errors.

How do you reprovision the internal SD card with the sim? If you are correct, some people may be able to fix the problem by doing so with their existing sim cards.

I would also LOVE to know how to do this!!! Very frustrated with this!! Hopefully reprovisioning the sim finally works!!

After searching around, I found to reprovision, you need to go to stock and dial this in the dialar, *2767*3855#. My question is,
- Is it def not possible to do this from an AOSP rom?
- When they say "go to stock", can I just flash a TW based rom and do it?

Agreed, I have reprovisioned before, to no avail. I thought it might be my SMS client, GO SMS, but I am getting the same NO SIM error with that client that I get with Handcent as well as the stock messaging client.
I called Verizon back today, to note my account that it's still happening, and spoke to them about a replacement phone. (I am already on my second S3 and second SIM) They offered me my choice of Android device, which currently is a bad deal. So I asked them if their deal would hold true once the Note 2 came out, and the nice lady at level 2 support said yes.
So unless this gets fixed prior to the Note 2... a switch is almost inevitable for me.

Dont waste your time doing the reprovision does not work I tried it earlier today.

Interesting...I might be doing the same thing. This issue is beyond frustrating. However, I have not called Verizon about it yet. Mainly because there doesnt seem to be a fix. I dont want a refurb S3 and there currently isnt a valid replacement. Might try the Note 2 if its possible.

call verizon just so that they can put a note in your account.

100% agree with Ripken... call them and have them note it in your account. Basically, I am documenting it once per day (it happens more, but calling more than once per day seems redundant) so they see it, but more importantly, I have some ammunition if I finally move to a new phone. Today's call to 2nd level tech support was a bit frustrating to me, as the nice lady said that, in fact, verizon did get a bad batch of SIM cards. When I pointed out that the bad batch must have been sent all over the country, because it's not a localized issue, and there was a software update addressing it... she didn't have a response. We went thru the same rigamarole with the phone... ie pull the battery, read the number on my SIM, read the numbers from my software build, etc. Again, she offered me any Android phone in exchange, which I turned down. But, at the end, she mentioned she was sending this issue up to a different tier of support that (her words) works with Samsung to fix these issues. I kindly asked her to have them address the headphone jack - bluetooth non-coexisistance, which she giggled at but assured me was working as intended.
So, back to waiting for a fix... or an inevitable new phone.

VRLHD Modem
Ok guys try this at your own risk! I might have found a fix looks like there is another modem floatng around called VRALHD I just flashed it in odin and guess what my phone seems to be working good here at home so try this at your own risk!
Download Link:
http://goo.im/devs/invisiblek/i535/modems
also if you google VRALHD modem galaxy s3 something will come up I cant confirm for sure this will help I will report back after some usage between now and tommorow.
Here it is on rootzwiki
http://rootzwiki.com/topic/34053-of...zon-sgs3-sch-i535-odin-or-recovery-flashable/

Guess I had high hopes for that modem does not fix the issues nevermind lol I am hoping when the jellybean update hits with a new modem this will fix the problem the waiting game begins.

Installed the HD modem last night. I have one area at work that I can test it. I'll report back later with my results.
Update: Flashed the HD radio last night (in CWM touch recovery), install went fine. Didn't have an opportunity to check it out till this afternoon when I put myself in a exact known location where I could reproduce the 3g/4g constant hand-off with the "no sim" notification. Sent out 6 text messages and a couple of phone calls with no problem. Either this new radio did the trick for me or it may be coincidental that Verizon has corrected this "dead" area that would produce this problem without fail everyday I was at work. Couldn't tell you for certain. All I know is that it's not happening anymore at this particular location. I used to have the "no sim" "out of area" notifications constantly at my home until just last week when Verizon finally covered this area with a strong 4g service. Only time will tell as I travel thru areas that have weak coverage. It's very obvious that this problem stems from weak coverage areas and the SG3's inability to handle the transfers effectively.

NO SIM 100, my patience, 0

Upon returning home from a business trip, the dreaded NO SIM error started creeping up on my phone again. 2.5 weeks in Salt Lake City, no issue. Back in TN, horrid NO SIM errors abound. I called Verizon tech support today, and he noticed I already exchanged the phone for a new one, along with a new SIM. One thing he mentioned, it looked like I was "roaming" in the system, so he reset some routers (his words) after having me pull the battery and wait a couple of minutes before powering the S3 back up. Sure enough, on the drive home from work, the phone had a NO SIM issue... so I unplugged the battery for the rest of the drive home. Once inside, I plugged the battery back into the phone, everything looked hunky dory, so I went about my business... and sure as s***, the phone gave me another NO SIM. So I contacted Verizon again, and she offered me any Android phone as a replacement. Now, I don't know if you guys have looked at the current line up for Verizon's Android based smartphones, but it's basically the Moto Razr or the Samsung Galaxy S3. I have not found a case that I absolutely love, so I have invested in quite a few so far, plus additional charging cradles, car mounts, etc... frustrating because I love this phone, but I use it for work, so I can't deal with this issue much longer.
If you had to select another phone to replace it, what would you go with? The new RAZR M? (lose NFC, smaller and crappier screen, etc) The RAZR Maxx?
Thanks, in advance.

No other phone on Verizon can touch the S3. Only phone that can be comparable is something that is not out yet.
Then when it comes out, they will tell you it is to new.

Might hold out for the Note 2. Testing something currently... wondering if Go SMS is the issue, seeing as the problem seems to creep up with some sort of combination of texting and calls. Will update tomorrow.

Did you apply the latest update? It should have updated automatically OTA, unless you are running custom unlocked rooted whatever ROM. In that case go to dev section and download latest radio and flash it. Should fix that damn no SIM problem.

Yep, already flashed last week. Tech Support told me tonight they have been fielding calls post patch showing it didn't fix the issue. If they are offering me any android of my choice, they are probably as flustered as I am. Almost went to a Rezound, a step backwards, I know, but I am at wit's end. Will see how the next week goes.

Sorry to hear. Try and hold out for a fix. I came from a rezound, and while I loved my HTC phones, this s3 is great. Too different to compare.

A fix is being pushed out today to address this issue. S3 is bar far the best phone you will find out there...

do you have a source about that?

Verizon is super frustrating. I switched from Sprint and got the Gnex, along with the "mute issue" where all of a sudden your microphone stops working during a call and you have to hang up. I've had the phone replaced and the replacement still does it so they offered me an "early upgrade" if I buy the S3 for $200.00. I did some research and found out about the no sim issue on the S3 so when I called back to tell them I didn't want an S3 they offered a RAZR M at $99.00 :/
I'm really considering breaking my contract with them to get a phone I like that works as it's supposed to.

Ya. This issue is really bugging me. I honestly believe there is a hiccup between the phone and the tower when a text is sent. I noticed at home that when I have wifi connected, and then send a text, the S3 will connect to 4G to send the message. At that point, something triggers in the phone and it loses connectivity with the SIM.
Not that this helps much... I explained it to level 2 support and they kept telling me how it was a new to them issue.

Not that this helps much... I explained it to level 2 support and they kept telling me how it was a new to them issue.

You're not kidding. I don't know if they REALLY don't know about these issues or they are just lying.
Tier 2 was who was helping me with the replacement phone and when I mentioned the No Sim error they said they had never heard of it and the only problem he's ever seen with an S3 is when a user doesn't turn off their old phone when activating a new phone :/

Ya, it amazes me that their "level 2" support still tries this excuse. Every time they try this with me, I ask them to tell me what the latest S3 software update addresses, and then the phone gets quiet, followed by excuses and them never hearing about it... even tho Verizon put out a patch to fix the issue.
Keep documenting it, tis the only way it's going to get addressed, or at the very least you will have ammo to get a new phone.

Have you tried the new HD modem for S3 yet?

Following guidance from the 2nd level tech after calling tech support, I stopped by the local verizon store today to pick up a new SIM. This is my third SIM, but she assured me there was a bad batch floating around the stores. We'll see... fingers crossed.

A friend of mine had the same issue, we both have the GS3 and live in the same area. She gets constant sim errors while I've never got one and I switch between 3G/4G frequently. She recieved a new sim a few weeks ago and hasn't had an error since. Seems a lot of sims are incorrectly configured with Verizon's network, just an educated guess.

I am amazed. 24 hours, not a single NO SIM error. Maybe I was un-lucky enough to get two bad SIMs the first time...

Still not a single no sim error. I am about 24 hours from saying it was a bad batch of SIM cards... never thought I would say that.

SIM Card gets disabled

Have any other crack flashers out there experienced no cell service, no data or stuck on 3g after switching roms? I'm on my second lte sim card?

I'm experiencing the same symptoms as you. Sometimes 4g will pop up but it mostly stays in 2g, 3g, or mostly None. I have tried going back to stock and switching roms. I'm guessing its Samsungs poor antenna design? Or could it be, because we are in the same area? And some s3's are defective and wont communicate to central NY's towers? I have gone to verizon to replace the lte sim card as well. I have seen a few others on here that are having similar problems with no real answer.

I'm in DC right now so I don't think it's the area. I was at a verizon store for like an hour while the guy tried to get the new sim card to work. I was on cm11 and then I restored a stock rom. Still no signal but i had data. Went to BestBuy to get a new replacement. Then the stupid thing started working like 15 minutes after I left. So I don't know if I'm going to take the replacement or not.

I was actually in NYC when it started. Was running PA3.99 at the time then kept flashing other roms and going back and forth from stock . Did they offer to replace it as defective?

Yeah. I have the BB insurance. The new one will be in tomorrow. I think I'm going to refuse it because I feel like going through the hassle and I don't think it's a hardware issue.

I'm kind of under the impression its a hardware issue with mine at least since it has very minor water damage. I may try to tackle replacing the internal antenna so i don't have to shell out the money for insurance. Although I have esecuritel, they have allowed me to upgrade devices(originally had a razr maxx). Also they give me a new phone out of box in store. So i'm kind of up in the air ATM.
