[Q] Have to Reboot to get the Network Back<<<<

ok, so i have this thing for a lil over a month now i think maybe more....
but i have noticed that no matter what Rom or Kernel, even Stock.
if im in an area where i lose signal.....it may NEVER come back unless i reboot my phone. not a big deal in most cases but unless i look to check i may have no network for a couple hours before i notice that i have to reboot my phone. which means i get no calls and no text.
is there a fix for this or is this just something that i am experiencing??

that is strange that it does not auto-reconnect. my suggestion would be to try a different modem than the one that you have been using, if you have not already tried all 3. find them here:
http://forum.xda-developers.com/showthread.php?t=1173704
both odin and cwm flashable versions. maybe you'll have better luck with signal with a different modem, so that your signal doesn't drop completely at all.

on my SD card i have had all three modems for a while now that i had been flashing to see which one i would stick with. but my phone has been doing this since day one. on any rom or kernel or modem. i just wanted to know has anyone else seen this or is this just specific to my phone........
at that point i would be looking to get another one.

you may not have to reboot - have you tried just toggling airplane mode on and then back off? that restores data when it goes out for a lot of people.
if you've tried that, and it doesn't work... not sure what to tell you, except to exchange the phone.
i rarely ever have a strong signal - usually worse than -100 dbm, especially at my house - but i've never had the problem you are describing.
hope you get it worked out. maybe contact at&t or samsung for support also, while you are on the stock ROM.

So far the airplane thing seems to work. so i will ride with that, it doesnt seem to happen but once a day or so......so if i can just do that then i will just deal.
thanks for the idea bruh.

No Network problem on samsung Infuse

GB baseband Canada??

Does anyone know of a fully working Gingerbread baseband for Canada?
I'm nervous about flashing new baseband and being unable to get signal/data on my device.
Thanks

Good Morning,
A couple of us have been discussing this in some other threads.
What I have found after flashing the GB Baseband is that it takes several minutes to register on the network. Once registered, voice and data work for a few minutes, sometimes only a few moments. Followed by a complete signal loss, that usually returns to follow the same cycle; sometimes only returns after a reboot.
I have gone back to FROYO for the time being. I heard rumours that updates for the Rogers Optimus 3D and the LG Thrill are expected by the end of the year.
I am not sure if the current baseband could be modified; or if the baseband from another GB device could be used or modified for use on our devices.
Thank you!
- Audi.

thanks for the information! Its too bad it wont really work. Froyo it is for me too then.

Good Evening,
Just an update. I reinstalled the GB KDZ for fun and it seems to have worked this time.
I have no explanation as to why.
Thanks, Audi.

Hi my friend.
Thanks for info again. Can you please let me know how you flashed baseband and kdz gingerbread ? Maybe ill try it.
Thanks

Good Evening!
I followed the instructions found here: http://forum.xda-developers.com/showthread.php?t=1287236
When I had issues and had to go back to Froyo I followed the same process to flash an early version then used the LG Updater to return to the stock Rogers rom.
Let us know if it works for you too.
More than 24 hours now and no network issues for me to report!
Thanks, Audi.

Thanks Audi!
Was flashing baseband difficult? What instructions did you use for that?

Good Evening,
When you use the method of flashing the GB KDZ file the baseband is included in the KDZ.
The instructions for flashing the KDZ are outlined in the KDZ thread in the Android Development Section.
Please let me know if you if I can help in any other way.
Let us know how you make out!
Thanks, Audi.

Only edge
I don't know if it's because of this or because my 3G reception was already bad.. Will be sure tomorrow but since this update my phone is only catching edge and i've checked my APNs and they're ok so i don't know what it could be...

Good Morning,
When you run speedtest (available in the market) what are your results?
As I said earlier I am getting the same speeds I was on Froyo; so I have no complaints.
Once the GB update is released in this area we will see the full benefits of HSDPA+.
Thank you, Audi.

well, I did it! I got GB loaded and running well. Although, as you and others have said, I'm getting mixed connection results. Sometimes it says 3G, others H but usually its E. At least radio is always connected though.
Sucks for me because I notice big drop in internet speed. I will do that speed test when I can and let you know what happens.
Thanks

On Rogers here too. Hmm, I tried this and ended up with a boot loop. Still working on a way to fix it back up. The phone just plays the sound, displays the LG logo then restarts and repeats.
Whoops
EDIT: Nah I fixed it, I forgot to boot and wipe my old data/cache. BUT, no HPSA. Just E. My apn settings are correct so there almost surely is a baseband issue here.
EDIT2: Don't flash your phone on a retard day. I forgot to enter the password on my apn thing. BTW, King3D rom had all the rogers APN stuff already filled in. Its pretty nice! Cheers

OK, I've had a little more time to test this... And yeah, unfortunately, there are a few nasty issues with this base band. Signal quality is very strange, e-only in a lot of places. Stranger still, my wifi is broken and drops its connection after a second or so of usage. This is tested on both the stock gb and king 3d (which is really nice, btw).
Back to froyo ;(
Really sucks, it sounds like people will be getting ics by the time we Rogers customers get gb. And they are getting gb now that others are getting ics, LOL.

Good Morning!
I am sorry to hear about your network issues; I wish I had could tell you why mine works!?
I had not yet tested wifi; just tested it this morning and it is working.
Bluetooth works great too.
I wish I had the answers to help more!
- Audi.

I suspect it has to do with the towers around where you happen to be. Rogers in Saskatchewan is a bit strange, it might be that with the different baseband its only talking to certain towers. Thats a guess anyway. Can't think of what else it could be -- I live on the first floor of my apartment building, I get edge-only. I visit a friend on the fourth floor and its HPSA and fast as lightning. No idea about the wifi though.
Cheers!

hi guys,
Mine has actually improved lately. I no longer have issues with connection, maybe once a day for like a second or too, but then its fine.
I am getting 3G more often now and H at times as well. I am in the Toronto area so maybe thats why? More towers?
Anyways, I found that I had to manually enter my APN settings to get it to work.
Bluetooth and Wifi work perfectly for me too. Although my battery life sucks big time for some reason. I think, when the screen is on, it drains like 1% every 3 minutes even when idle!
Thats brutal! There must be some blood sucking LG apps that are eating my phone for breakfast, lunch and dinner!
I guess I have to do some digging to get this GB running super sweet!

Sim card not allowing connections? [Help]

Flashed a few roms on my phone and never bricked it whats so ever. It shows the IMEI, how ever it doesnt match the IMEI it have on on the back of the phone. The phone came with 2.2.1 Froyo and i upgraded it with ODIN using KJ6 2.3.6 GB rom. I can connect to wifi and such. It's not the sim card cause it works with all my friends tmobile phones. I get bars on the phone with the sim card in it. But when i attempt to make a call it says "Not registered to Network" i went to Settings>Wireless and network>Mobile Networks>Access Point Names, i went there to do the APN Manually i tried setting it to Default and it didnt help either.
Anyone know's how to fix this?

Thanks for the quick reply, Does it have to be exactly 10mins? Not to sound like an idiot.

I'd say at least 10 minutes, going longer won't hurt.

Alright , Im giving it 20mins. Hopefully it works. It's been too long and i'm starting to give up on this phone.

Still having a problem, You know any other solutions? I don't wanna have to pay for a new phone lol. If you do can you have it in FULL DETAILS. Cause i want to make sure i have have every thing correct.

I got all day to try to fix this. I don't want to try reflashing things cause i don't know if i can mess it up or cause more problems.

So.... you have flashed a few ROMs..... meaning you have at least ONE nandroid back up from when the phone worked?
If you do... you are good to go. If you don't..... good luck to you. You have what sounds like a generic IMEI.

Well i don't, didn't know i have to. So in other words it's impossible to get this phone back on?

I had the same issue with my phone, it just wouldn't stay on Network, and the SIM would go back and forth from being recognized or not. I flashed back to stock and it still didn't work. The ten minute battery pull was suggested in another thread and a few people swear it works. Mine played up before this was suggested so I never tried it.
I had the same thing happen with my wifes phone and all I could link it to was the Kj6 modem...see link below. I reflashed the whole ROM and it came back.
With my phone I just called T-Mo and told them that since I upgraded to 2.3.6 via Kies that my phone wasn't working properly (Technically true, but a little stretch). I flashed Bhundvens 1click to stock, factory reset, etc...etc... then paid $20 and got a replacement phone via UPS in about 4 days.
I not saying you are having the same problem as I did, but it sounds very similar.
As a side note, the replacement SGS4G (refurb) they sent me absolutely blows my original handset out of the water when it comes to signal strength. I get solid 4G speeds of 5MB+ in my house, where before I only got patchy edge. I was amazed at the huge difference in performance between two supposedly identical handsets.
I hope you can get this remedied without an exchange, but you should be able to get a new one for $20 as a last resort.

Back ups are suggested all over this forum. Now you know. It is not impossible... google 'generic imei' and look at the dozens of ways people have had success and failure trying to remedy it. There are a ton of threads in the SGS 4G forum alone.
And whether you fix it or get a new phone... make a back up of your efs folder FIRST thing along with a nandroid back up. It will save your ass if this ever happens again.

Atleast i managed to Flash and root the phone with out failing nor bricking the phone. Even though it was my 1st time. Majority of new comers get there things bricked. But anywho yes, ill always make back ups for now on.

Still having a problem, anymore ideas anyone??

Data connection issues.

Hi. I was using my Sensation last night, went to bed and woke up the next day only to find that my 4G connection wasn't working! The signal bars were white and the icon (currently an H) is flashing. What does this mean? How can I fix it? I can only use Wifi at the moment, and I DO NOT pay an extra $10/mo to deal with this! How can I fix this? I've checked my data settings, rebooted my phone, scanned fir viruses, but can't figure it out!

this happened to me the other day, even in 3G/4G mode my data would never connect and E would just keep flashing over and over again (in like 10 sec. intervals) thought it was a ROM problem so I restored a backup and sure enough, the problem was still happening. I could still make calls and send texts fine tho. its not happening to me anymore, but I found it weird. could it possibly be T-Mobile messing with their towers or something in preparation for LTE?

Well, I'm not sure what caused this very same issue for me a couple days ago. I can say that it ONLY effected my AOSP (CM9) rom, but my Sense rom was unphased. It seems to be a common recent complaint in the OpenSensation thread...
I've since then done a fresh install of CM9 RC1 with the addition of Tamcore's kernel. Although I'm not experiencing the described symptom any longer, I can say that my data speeds are far from exceptional. I'm not sure what is going on, but it does seem to be carrier related.

I experienced the same 1 day after flashing CM9 RC1. I re-flashed the Virtuous Inq. ROM I was using previously and the problem went away

My phone went back to normal later on. I think you were right mulletcutter, they might have been servicing it.

Same data connectivity issue
I have two sensations, both shows similar data connectivity issue on TMobile. Data signal jump to connected and not connected for couple hours, and eventually problem will go away. I have both phones rooted running either CM9 or Kang. So far I have tried couple following things but no solutions. I believe its HTC Sensation hardware issue:
1. Flickering so far seen usually after night long charge in the morning. It will last couple hours, some time days.
2. Changing/reflashing ROMs did not help at all and saw same issue continued.
3. One of my friend has Sensation and he also has seen same issue.
4. Some time going into Phone application(Dialer) and then Settings/Advance settings and come back without doing anything helps but not always.
Please post here is you have temporary/permanent solution or even know the root cause of this data connectivity issue.
Also thinking to call Tmobile to get some kind of help but not expecting much as I bought phones more than year ago but less than 2 years. I don't want to give any more commitment/agreement with Tmobile as planning to move to value plans to save some money. If Tmobile does not help, thinking to try American Express to conver it under extentended warranty as I paid by AMEX credit card.
Thanks

Have you tried the application get ril? I was having some issues myself, I'm also T-Mobile. I tried get ril and found out my radio and ril we're not matching. The application suggested a ril for download and once I did that I went from one bar of connection to five bars of connection on H. It made a big difference for me. Perhaps it could also help you? You can download get ril from the market. It sure won't hurt to try. Best of luck.

Its a defect in the basic aosp framework. There is nothing you can do to fix it. There is also nothing your usage did to start it.
The good news is that it should disappear on its on after a few hours.
Check my threads started history. You will find a thread near the top of that list showing almost all there is to know about this issue. I think my thread might be linked in the first 2 posts of the cm10 faq thread too.

Did I cook my WiFi?

I am experiencing terrible WiFi reception. This seems to be ROM independant. I flashed back to miktouch to get a stock kernel and see if it went away. I've moved from cm9.1 to aokp/jb and have the same problem.
I have never flashed a radio on this phone. In fact, its still s-on (please don't laugh, it keeps me from getting too excited and wiping my phone in a truck stop parking lot!)
The only thing I can think of is I tried overclocking it all the way to 1.7...it behaved very strangely for a minute before crashing and rebooting. So I set it back to 1.5 and went on my way.
Could this have damaged the wifi portion of the SoC or its tiny antenna connections?
Sent from my doubleshot.

Try reflashing just the Wifi modules. Click on the "Blue6IX" link in my signature & look in the 4th post, I believe, then pick the one you need. Couldn't hurt.

So, all the way back to stock, and still almost no wifi signal.
I've finally gone to the point of applying PG59IMG.zip onto a relocked phone, thereby restoring everything including the radio to absolutely stock, and still I got ****e for signal. So I guess something is broken, physically. I dread having to send this one back to T-Mobile. It's my third MT4GS in 6 months!. (The first died four hours out of the box, the second I warrantied after a couple months when the e and u keys started repeating to the degree that the hardware keyboard was useless.)
They're gonna start to hate me...and the sad thing is, It's not even the hacking that breaks the phones! (Maybe the dropping.)

Wow it's either you're an unlucky guy or mt4gs hates you
I had only a one and a second hand mt4gs which got dropped several times by the previous owner and it's been very2 stable to me since the 1st day I got it. Didn't have any hardware issues at all.

Before giving up, try installing a ROM AND fastboot flashing the boot.img from it. I'd suggest either Bulletproof or Miktouch. If I remember correctly if you are S-ON you can't write directly to the partition for the radio using the phone, you can only do it externally. So maybe somehow that partition got botched and reflashing the boot.img through fastboot may fix it. It's worth a shot.

Yeah, I actually drop this thing so much, I couldn't get $50 for it with all these nicks... Still works perfectly tho
iPacman

I always fastboot-flash the appropriate boot.img. this problem persists through all roms, including stock-based, aosp-based, and even relocking and flashing factory firmware as per blue's dev reference thread. Sad thing is, I love my phone so much that so far I'm just living with it. I have unlimited data, and at home I have 2 dd-wrt access points in repeater bridge mode for an 800 sq. ft. house! Everything thing else can hit both full strength. I can hit one or the other.....
