Hi all,
Today I find out that my phone is not connected to Rogers network. I have US phone unlocked and unbranded. I had for 4 months now and never had this problem. Right now, when I go to Wireless setting and try to find operator it keeps looping to find one, any help appreciated.
I had to RMA my phone when this happened
I'm sorry to hear that you lost signal to Rogers. My Captivate had the same problem over the weekend (not connecting to AT&T).
My local AT&T store couldn't find anything wrong with it but recommended it was a hardware problem and can be exchanged for a working phone. Even trying a new SIM card didn't help. Luckily I had flashed to stock and had complete Titanium Backups of my apps & data.
Typing *#06# in the phone dialer brought up my IMEI number. The IMEI displayed should have been the same as what is shown underneath the phone's battery but it was not. It started with 004 instead of 351.
At this point I'm not sure the malfunction had to do with a hardware issue or my ROM flashing hobby. All I know for sure is that I made sure to backup my EFS folder before flashing another ROM.
Generic IMEI number starts with 004
It's hard to stop a TRANE but harder to BRICK your GalaxyS. It's not a hardware problem U have software is your problem and it's easy 2 fix. Just flash back to stock JH7, after that do an ODIN3 Master-Clear. When ur done all will be GOOD ur IMEI will b correct, network will be back
Hello,
I have searched multiple forums for hours today and have figured out what is going on with my HTC Vivid. (It has been upgraded to AT&T Official ICS.)
It was working fine up until yesterday where it was not receiving a signal from the mobile network and the signal icon has an X through it. The SIM card is properly inserted and another SIM card has been tried as well. Looking through other threads it seems like the Radio RIL files may be missing or corrupt. The IMEI number and *#06# code does not show an IMEI number either. The baseband version says unknown. I am not sure what happened as I have never loaded any other ROM on it.
I downloaded the Official RUU ICS upgrade ROM today and tried reflashing it, with no luck.
What is interesting (and the other person who had the radio problem) is that when I left the phone sit off overnight and then turned it on in the morning, the phone connected to the mobile network and I had a signal. When I restarted the phone, hours later, the phone lost connection to the mobile network and that is when I started digging and found the problem with the baseband version being unknown.
Is there anything anyone can suggest? Can I reflash the baseband files or copy them from someone somehow using ADB? It seems like there is where my problem lays. I've searched for ways on how to downgrade from ICS to the official GB stock rom, but it doesn't seem like it can be accomplished.
(I tried downloading the Holiday Cingular version of the GB stock rom but the update failed. I read about the ICS HBOOT version being different and not allowing it.)
Thank you in advance for helping and any suggestions.
Have you gotten a new sim card yet? That needs to be your first step. My captivate did the same thing and turned out the sim went bad

Yes I have tried a different sim card. I don't believe thats the issue though being that it worked with the same sim after I let the phone sit overnight. From reading about others experience, it doesn't seem that the sim is the issue but more the baseband version and imei information missing.

I had a similar problem and thought I solved it, but I later realised all my "solutions" didn't bring back the network but coincided with its reappearing cos no same "solution" worked more than once.
It's a very weird problem as the network shows up once in a while and when I'm using Mobile Network for Data, my phone hangs again and the IMEI, Network, baseband disappears on reboot...till further notice. I gave up trying and concluded it's either a bad modem (hardware) or something AT&T knows about!
You can get HBOOTS for both GB and ICS via Hasoons AIO kit
Flash the HBOOT, Flash the Image from Cingular GB RUU and I wish you luck!!!

I found the download link, but the website says they're updating their drives, so who knows how much longer that will take.
Also, are you saying I should just use the tools within the kit to flash the HBOOT back to the previous version compatible with GB and then flash the RUU GB image after? Can I do that with the phone connected via USB or does it have to be flashed from the SD card? If it has to be flashed from the SD card, how do I go about doing that? If it can be done from the phone via USB, does the phone have to be in recovery mode?
I have tried reflashing the ICS RUU multiple times w/ version 3.26.502.52 and 3.26.502.56, both do not fix the issue. Do the baseband and or radio files NOT get flashed within these updates?
Thanks for the response!

For any issues downloading Hasoon AIO tool, please use his thread (earlier provided).
Yes, use the AIO tool to flash GB HBOOT or read the SUPERGUIDE
and obtain rom.zip from the Cingular RUU
I don't know how to flash RUU via Recovery [email protected]@@!!!
I'd advice you follow my first solution here!!!

Thanks for the quick reply.
Your thread was the one I saw earlier with the simliar problem that I am having, only I have not loaded any custom ROMS. The phone just stopped receiving the signal the other day. I am still waiting for the download website to become available to use the tool to perform the flash of HBOOT, however, once I do that, will that erase the ICS rom from my phone? If so, what steps do I have to perform to get it in a "download mode" to accept the AT&T GB RUU? I'm a little confused on that part.
I read your first thread and I am a bit confused on exactly how you were able to correct the baseband/RIL issue (which I am assuming is the root of my issue). Do I have to extract some files from the RUU executable? Are the commands you provided to be used in ADB? I am confused as to what to do with [setprop ro.baseband 3.26.5XXX (<--- mainver: in android-info.txt in RUU.zip)] from your post. If that command is copying a file or just setting information (almost like as a registry setting within Windows) to point to the file or set a version number. Also if the XXX needs to have a certain number.
I thank you for your time and am trying my hardest to understand what to do to accomplish these steps.

I did find the extracted files within the RUU executable and found the rom.zip which included the .img files among other files I assume needed as sources to flash the phone. I see a radio.img file would I be able to do anything with that?
Thank you.

And I have a question, if the radio/baseband files are included in the RUU flash, what is happening as to why it is not being reflashed, or if it is being reflashed, why it is disabling the mobile network and providing an Unknown version to Baseband and clearing the IMEI number?

Here's where I am:
I successfully unlocked my bootloader, downgraded to GB, rooted. Tried to gain root access through adb terminal but it was not working properly.
I relocked my bootloader. Installed the ICS RUU AT&T ROM update. Unlocked my bootloader, rooted.
I see the commands you ran in your previous post. I am also receiving the same message of N/A when running the getprop ro.baseband
I tried the second command setprop ro.baseband 3.26.5XXX and then restarted the phone. I have tried it as posted, and also with swapping out the version that is located in my android-info.txt file: 3.26.502.56
Still no luck with setting the baseband version. IMEI still is cleared out.
Am I doing something wrong?

Please see my initial quotes above...
All the previous steps I took were only a coincidence (not proven to work)!!!
We may need to contact AT&T to be sure its not a lock IMEI (and I'm wondering why it would be) or an experienced Dev

Hey thanks for all of your suggestions. I contacted AT&T the day everything happened to see if it was on the block list. They said no. I tried multiple things including trying to re-flash the radio, but I was getting a signature failed error that I could not get around. I really think that's what the problem is. I gave up and ended up selling it.

I gave up and ended up selling it, as is, on ebay instead to get a few bucks out of it and getting a new phone.

I really wouldn't mind selling mine too if I get a buyer. I'm just tired of all the troubles and no dev is willing to help.

Exactly. It was my sister's phone. The sh*tty thing is we bought two off of ebay at the same time, 1 for me, 1 for her. Well, her phone was not in the box (either never shipped or stolen) so I had to file a claim through eBay which took 3 weeks to get the money back. Meanwhile, I gave her my phone (which is the phone in reference) to use instead. I bought her an iPhone instead now, along with purchasing one myself. I loved Android, but the bugs and fragmentation is getting too much for me to handle.
Dude, if you don't have an IMEI showing up, something is WAY wrong. That goes beyone the RIL not working... The RIL is probably fine. If your phone doesn't have an IMEI somehow, the cell towers are NOT, NO WAY, NEVER EVER going to register your phone on their network. You can put a billion SIM cards in there, or flash a billion stock ROMS, and if you don't have an IMEI, you will never be able to connect.
Something is probably corrupt or broken in your firmware or the hardware itself. I think your device is probably screwed.
My advice, is follow the steps to put your phone back to stock (including changing the bootloader message back to **LOCKED** and S-ON), and get it back to the phone company. They will be able to tell something is boned on the phone right away since it isn't displaying an IMEI.
Sorry to be the bearer of bad news and for your many wasted hours... But on the plus side, you now know a LOT about flashing and how your phone works now
Good luck with everything man! Hope they get you up and running soon!
I have the same problem as the OP but I have a IMEI showing up and a Basehand But won't connect to AT&T or anything they resent me a Signal & everything it shows a X with no bars it happened after I did a Factory Reset
anyone got the Radio.img?

That's weird..you try creating the apns again? I don't see how a factory reset would do that. Try toggling airplane mode too

I am currently having the same issues right now, it works if i leave the phone off for 1 hr it will work until i reboot then its down again, tried every thing possible, airplane mode will crash, reflashing the radios from gb and ics does nothing, setprop does nothing really. from this point it feels like a hardware issue.
sorry to revive an old thread, i just wanted to know if anyone came across this issue and had it fixed
i will get a log to see if there is errors showing up
Return it.

I just got a used AT&T Vivid with what turns out are 2 anomalies that I failed to observe initially.
First I tried to put my ST sim card out my AT&T SGS, and get no service. No big shock initially since I have to change the APN info. Couldn't do that cause option is dimmed.Checked further, No IMEI, IMEI SV, or baseband. Took sim out and observed that I get NO sim error at startup, just "no service". Tried an AT&T sim from a friends Vivid, same result.
I was hoping that the sim card reader just might be bad, a cheap easy fix and apparently some what of a common issue. Haven't ordered one yet until I get more info on whether the no sim error and no IMEI etc are related and it's not a more serious hardware issue. I don't have a problem with repairing hardware if needed.I'm a noob here, but have a brain like a sponge, so any thoughts on how to proceed with diagnostics would be appreciated. Thanks in advance
No imei is really bad...
No one here can help you recover it without a proper backup... I have no idea how to back it up nor restore...
If you don't figure it out I'd have to suggest flashing to stock... prolly via ruu and go to an at&t store...

I don't think (but don't know 4 sure) that this phone is anything other than an out of the box stock configuration. I don't have service with AT&T so I don't know how much help they would be. I did check with them to make sure IMEI printed on the phone wasn't blacklisted and it's OK. All I have done was to do a factory reset to clear all the PO's stuff.
Does anybody have any more ideas? I am wondering if I don't need to replace the motherboard and or just the simcard/sd part. Changing the motherboard would mean a different IMEI right?
No imei means something went wrong with the bootloader. It's unlocked? Did you try to S-OFF?
I believe flashing a rom stock via RUU (that's it, flashing the PD.zip file) maybe can fix the problem.
At worst you must change the motherboard and yes, you will have a diferent imei.
I may be wrong, but I see no sign that anybody has done anything to change ROM or anything else on this phone. I'll try to do a S-off, and unlock it since I want to use it on ST anyway.
hello,
i've also same problem here
flashed with stock rom but no luck ,
bootloader locked and s-off
searched forum but no success story
i think i'll return it
Well I finally got a new SIM/SD card reader and installed it. No change.Tried ST, AT&T, and T-mobile sims
Still get no SIM error when booting with or without a SIM card, has an X on signal strength, and it doesn't even say "no service".
Same as to IMEI etc. info, nothing shows up.
Am I going to have to change mainboard? Or is it possible firmware/ROM changes could fix it?

Unlocked the bootloader tonight, no problem. Will try s-off tomorrow.
Where can I get a stock rom file?
I'll only ask this dumb ? once: Is the OS (JB,GB,ICS) different than the rom? I'm still running gingerbread 2.3.4, should I got to ICS or? Will that have any affect on the imei issue?
I might just be getting some experience with this phone if I have to do it all over with another mainboard.
OK, so I decided to play with this phone again after my SGS1 was freaking out yesterday. I finally found and used a phone dialer code do download the ICS update, and it downloaded (via wi-fi), installed and rebooted fine. In fact It apparently fixed my IMEI and SIM card problems because when it booted the first time with ICS it showed a big icon "no SIM installed" ya hoo!! checked IMEI in settings, all was good. Played around with settings/menus a bit to familiarize myself with the differences, then restarted...NO IMEI again, and no sim error without any SIM installed On the next 5-6 restarts it worked fine all but once, (total on time of around an hour) but now every restart (10+) it's back to same original issue: no IMEI shown and no SIM error. I still have no AT&T compatible SIM card to really test it but if it doesn't give me a SIM card error (no SIM card installed) it's a moot point.
It really puzzles me that it appeared to work at all if I have a bad mainboard. My daughter in-law has a Vivid with a bad screen she's going to give me to use for parts (mainboard) but I'm not sure if there's not still some hope of salvaging the current one.
Comment, thoughts etc... Please
Hi everyone,
Hope you can help me solve this, cuz I'm way out of my knowledge..
My phone broke the lcd and was out of action for a few months.. After I finally got a replacement screen, the phone wasn't working and said IMEI unknown, I've tried to flash a few roms via recovery but nothing. So I just went crazy and flashed it via kies. It worked, the imei appeared but the phone was locked again..
Back to the shelf a few weeks until I could afford to pay for unlock.. When I picked it up, it was unknown IMEI again and the guy at the shop basically told me he couldn't help.
Was he right? I refuse to believe I can't recover the phone.. Can you please help?
Thanks!
Anyone?
Are you sure is that phone imei is not blocked, because provider may block if it is stolen reported.
I had the same problem after changing display IMEI unknown
But somehow it was saved from 'unknown IMEI' I don't know how.
restored efs from previous backup (twrp & philz recovery)
- no imei
I flashed stock
- no IMEI
asop
- no imei
tried different modems
again stock
- suddenly its worked
(some users reported flashing different modems worked for them)
Yes I'm sure imei is not blocked by network. Have a friend that bought a phone which he discovered the hard way it was stolen, anyway, blocked imei by network behavior is completely different.
This is what happened to me first time only valid imei after kies rom update.

If you see imei again, Make a backup using pc, there is a guide in development section. So, you can easily restore again.
