[Q] Loss of signal( LOS ):confused: - Vibrant Q&A, Help & Troubleshooting

here's my problem:
when ever i leave phone to be in deepsleep mode,
i cam back to find it looking for GSM signal with no hope,restarting fixing the signal.
tried diffrent roms, CM7, MIUI,with all kind of kernels nothing works
phone condition is fine,did't drop it or hardware issues on it.
was working great for last 6 months, but after i flashed a ton of diffrent CM roms this starts to happen,
my thoughts:
could it be a NVdat.bin issue doing this?
if so, what i can do to let the phone re build fresh ones,
+ i have old backup of EFS folder.
can you share your thoughts please?

I had the same thing happened to me and my friend's phone in the last week. Both running the ported gingerbread roms. Had to Odin back and finally working. Not sure if it was the Rom or something. My phone says it shows a baseband of UVKB5 which is the correct modem.
Finally flashed back to froyo and had it working, now just reflashed a gingerbread rom and it's working again.

[Q] Flashed HTC sense ROM Odin to stock Now no Mic on inc/outgoing calls

SO anyway earlier this week I was screwing around with some roms I had decided to try the team galaxy sense goine rom it stopped working for a few minutes but then the screen wouldnt turn on so I went into download mode and flashed back to stock with T959JFD & 512.pit and then I went ahead and flashed to the new m9 rom and to my surprise my microphone does not work anymore on calls it is constantly mute but not showing the mic muted and since forth Ive tried odin on almost four sperate occasions and different roms including axura and nero and have done so for the last 16 hours to no avail the only thing I have not tried yet is installing a Fresh JL5 Rom, Modem and, kernal would this most likely fix my problem? any help would be appreciated thank you
EDIT: Tried the jl5 modem and kernal this problem seems to persist regardless of which rom I flash what the **** is the problem with this thing

[Q] Lost signal in new CM7 Kernel. Anyone else?

Unfortunately I can't post this question in the thread that the issue originated from but :
last night I was on com rom 2.0 with OTb1.6 kernel and ec01 radio. I did the ODIN flash to DL09 modem and then up to ED04. Had no issues at all. This morning I decided to take the plunge into gingerbread and used this thread here JT1134 CW7. I played around with this for a few hours and didn't seem to have any issues besides the known bugs. So then I decided to up to the newer rom by nemisis2all
Nothing seemed to have any issues in the orange CWM while applying the update
Now I have no signal.
Has anyone else experienced this?
Also is there a link anywhere for just the original kernel from JT1134 CM7 test build 06/09
EDIT: looking at the phone status is says baseband unknown. So I think I'm just going to wipe all and go back to the original 06/09 build byJT1134 unless anyone has just the kernell.
Thanks up front

You should try flashing a recent modem first to see if that resolves the problem. I am using EC01 just fine with the 6.09 build from the thread you linked. I have noticed on occasion mobile data will drop, but it seems toggling wifi fixes that (cannot say for sure). But I have not had any problems with voice signal.
It is still an alpha, so keep that in mind, but it has been working great for me.
with the ED04 modem, I did have the signal drop for a few moments earlier, but it seemed fine after reboot. and I have noticed that the mobile data does drop occasionally after being on Wifi for a period of time, but reboot seems to fix that too.
Ya i even just tried to flash all 3 times data, dalvik, cache and then install the CMW7 test 2 from JT again thinking it would jsut revert to the old kernel included in his and work again. But it is still no signal and no baseband version.

I probably should have read in a bit deeper, in order to flash to the ED04 modem I actually had to flash back to a touchwiz rom then flash over the DL09 and I used CWM 3.0.x to flash up to ED04. I had tried to do it in the orange CWM that came with CM7 test 2 and it failed multiple times. After I had gone back to DL09 and updated modem I just flashed CM7 back over and have not had much problem since other than data dropping.
I Just Odin the modem back to DL09 and then CWM Orange from DL09 to ED04 and working again. Thanks for the input guys.

[Q] No Service After Flashing ICS Passion V4 ROM

So, xda won't let me post this in the actual ROM post, but I was wondering if anybody else was having this issue (or new a work around). After installing the ICS Passion V4 ROM, I've completely lost all service (says emergency calls only in the notification tray).
I tried manually setting a couple things in network settings but nothing worked. I eventually flashed back to Froyo with odin and all is well (so it's not a hardware issue).
Any suggestions?
after flashing passion look in setting - about phone and see what's listed under baseband. It should be T959UVKB5. If it says unknown you need to flash the KB5 modem that is in the OP.
Ahh, duh! Now that you say that I remember reading that exact thing and making a mental note to try that if I run into problems.
Thank you so much! I'll have to give that a try when I get home tonight, I'll update if it works.
Yup, that fixed it. Thank you!
Now i have that problem
i have no service either and i did flash the KB5 modem. not sure if im doing anything else wrong. my baseband says unknown and and its been the same when i had cm7 running.
any help??

Android 3G going slowly?

So i tried some different modems on my i9000. and i decided to go back to JPY (original) before I couldnt flash them in cwm for some error. so i flashed all the modem.bins directly through odin and everything went well, After a day i decided i didnt like the battery life so i went back to the JPY modem. But now the internet is so so so slow it just times out. I have even restored the apn setting and everything, (GSM/HSPDA is on) Data mode activated. It just hardly works. Am I going to have to reflash my custom rom? Simplicity Rom 2.2.1 or 2.1.1 or whatever. ?

So you have the captivate? If so yes you should reflash the rom.

[Q] No CDMA Service on Custom Roms

Hey guys, I'm not new to rooting or flashing ROM's but I've encountered some issues. Basically, I was on an early JB Rom and everything was working fine but it mostly was in roaming and would go from 2-4 signal bars.
I backed up and have attempted to flash:
PACman
MIUI 2.11.23
As well as CM10 by joker and AOKP CM 10.
Every flash I end up with no signal bars and no roaming, also following all install instructions in the threads.
I have tried flashing with and without prop tweak, i have even restored the backup all with the same results:
Empty signal bars, occasional R for roaming, every call says mobile network unavailable.
I have also fixed permissions, and have tried to flash via TH3Bill CWM and TWRP recovery... what am I doing wrong? The backup isin't even working!
I wouldn't know off hand, but here's something you can try while waiting for a more professional member to come to the rescue.
System Settings> More>Mobile Networks>System select>Home only
What's your current PRL, APNs?
if it was me I'd sbf back to stock and see if I had signal then go back and try a custom rom again

Before sbf'ing if you have a back up of your stock ROM or any ROM that has the update profile/prl setting in it, restore that back up and try updating your profile/prl then wipe/flash your new ROM.
I usually have this problem when I switch back to my Photon from my ET4G, but updating the profile usually does the trick.
When I restored my old backup, I had the same problem. The only fix I could find was on MIUI and selecting automatic netowrk before flashing options chooser. Any other rom would make no changes on automatic or home only. I am going to try a fresh install and if no luck will sbf today. I'll keep you guys posted.
Thanks!
**EDIT** Does it matter if I use Th3Bill's CWM recovery or TWRP? I have tried both with similar results. I jut noticed CWM is usually posted with the ROM builds... does it makes a difference? If so, what should I use?
Normally both work just fine, as long as you're using one of those two
I spent too much time flashing roms and wondering why they wouldn't work right, when I was using the stock CWM
I think It's just my opinion but I have preference for bill's cwm
Having this exact same problem. Did anyone figure it out?
No Radio/Signal
I recently flashed the latest MIUI.US V5 3.4.5 for the Photon provided by Th3Bill. I am familiar with the process of applying ROMs. I tried to go back to Beanstalk, JB, and ICS and could not recover the radio signal. I even restored a few backups with the same result, no signal. I flashed the MIUI V5 3.4.5 ROM back to the Photon and it worked flawlessly. Can anyone please help? I would really like to get off the MIUI ROM, it does not appeal to me like the standard versions of Jelly Bean that Th3Bill has produced.
