Hi guys,
I flashed my phone with the latest checkrom revoHD V6 as per Spider's instructions (full wipe). Afterwards my phone couldn't connect to 3G. Wifi and 2G work ok. So I flashed the same baseband I'd had previously, but that made no difference. So I flashed back to the restore (VillainRom V3) I'd made with CWM before checkrom. Now I can't even connect to 2G. I tried reflashing the baseband, but again no difference.
Any ideas of what to do next?
Cheers.

Check your IMEI (*#06#) and report back.
Don't post your full IMEI or anything, just say if it starts with 24 (I think) and has loads of 0's in it, that's the default development IMEI.

Hi rev,
Cheers for that. I checked my imei number, but it was blank (small panic). Having just read that some people got theirs to reappear by turning off, removing sim, and rebooting, I tried that. It worked.
I also have a efs folder back up.
I think the problem may have occurred because I flashed the modem (using CWM) while the ac charger was plugged in.
Lesson learned: ALWAYS MAKE A FULL BACKUP, ESPECIALLY THE EFS FOLDER.

Yeah well I flashed Jose51197 miuiv5 Rom and had no signal, was expecting that since it was a port, but I booted into recovery wiped ( factory reset, cache, and dalvik cache ) and restored back to 4+ but once booted it showed a trangle over my singnal bars. And I read in Jose's post that you had to set apn manually if that happened and wipe cache&Calvin but it still shows the trangle. What do I do I know it means roaming. And can't connect to Verizon, send text but under settings> enable data roaming then I can only use settings> select find data network, and it connects to some service

Which ROM is your phone on?
Do you know your APN setting?

I had the same problem till I ditched TWRP for CWM. My I717 seems to like ClockworkMod better. Just couldn't get TWRP to flash the modem correctly. *#06# will give you the "Null Null" IMEI message if you have the same problem as me. Use Kies to recover and initialize the device, its under "Tools". When done you will be on JB with proper IMEI. Flash CWM through odin and go from there.
**EDIT**
Turns out that the problem I was having might have been because of outdated modem files. The issue is resolved for me with the modems at the following link. 4g lte has never been this fast before these drivers. Fast and stable, be sure to give the OP a thank you.

I've been having the same issue. I started with Stock, went to CWM ver 6, CM 10.1. Decided to flash a modem, and then it would say unknown baseband / no phone number / no IMEI. After trying many modems and restores, I have restored through KIES back to factory as of now.
If anyone has an idea, it would be appreciated.
I live in Florida the only way I get 4g LTE is with stock modem...I used to have the same issue...so I just keep it stock...

no need to do anything.just go to app setting ...running ..you will see ''sim'' app running just close it and restart your phone it will show your imei ...n baseband all....
Well the problem is that My phone has lost it's IMEI.
It happened when I was using my phone and it started lagging, therefore I restarted it and after that it has stuck in the 'Airplane mode turning off'
Radio is not working, I think because IMEI is lost unknown that is why.
I Flashed Boot.img , custom roms and reverted back to stock rom but all in vain
Local mobile repairer said that he cannot fix it, therefore I went to another and he also failed.

Do you know how to access fast boot? You may have a bad radio you flashed. I flashed a bad radio on my Nexus 4 before on fastboot and I got those IMEI unknown. Best bet is to check the HTC One X section here on Xda and look for a collection of radio's thread and download it and flash the radio via fast boot.

It happened before flashing anything. My phone was stocked when this happened and after the issue happened, I flashed the phone.
Hello,
I didn't do the system update before rooting the device and perhaps I should have, with the epic, touch, and note2 it was a bad idea to do system updates so I just skipped it. I rooted the phone and flashed TWRP on it without issue using the tools from galaxynote3root.com's. I then made a backup of the rom using TWRP. I then went to flash Galaxy-S-fre3-MD4FirmwareModemAIO.zip through TWRP which I think is what killed it but i'm not 100% certain, I just know it errored out / wouldn't let me flash the zip. I tried restoring from the TWRP with the backup I made, no luck.
I'm now stuck unable to get anything to boot stable, it always shows "Process system isn't responding" and dies shortly thereafter. I can occasionally get to the point where it sees icons but usually it just reboots. I think I might have nuked the modem but I can't seem to find a radio/modem thread for the sprint model and I don't know if the modems from the GSM thread are safe for the Sprint.
I have tried flashing N900PVPUBMI3_N900PSPTBMI3_N900PVPUBMI3_HOME.tar.md5 on it through Odin with the auto reboot on and off without luck.
hmm

flash the odin tar reboot into recovery wipe data and cache this should get you up and running

Ah forgot to mention that I tried that, no joy. It goes through the caching of apps, sits forever at 'finalizing boot' and then goes into the reboot cycle.
Restore doesn't work and once u do that it borks your file system. Your phone is bricked and using Odin to go back to stock will not work. You can try but u need to get ur phone replaced and hopefully sprint doesn't look at your knox counter if not u got ur self a $700 paperweight
