No 3g - only edge

I recently flashed my G1 to:
CyanogenMod 1.4
JACxROM-v1.3r3
ota-radio-2_22_19_26I
and the newest SPL
I've noticed the phone never actually gets 3g connectivity anymore - only edge.
Any clues?

Hmmm, that is really weird, did you check the settings and make sure the Use 2G network only is not checked? I dont get 3g either way because I am using att but I dont see why it would affect anything like that when you flash a rom.

Yessir. Its unchecked. I noticed this same problem as well back when I had my ATT Tilt (htc kaiser). Soon as I started flashing roms and radios, I lost all 3g connectivity. Had to go back to the dealer to get a new chassis.
REALLY hoping that isnt the case with this one. Did a speed test with wifi tether - I have four full bars of service, but I'm only getting ~20k/s downstream and the symbol by the service indicator bars is an E
I'll have some more time today to test it while out and about, using other towers and I'll report back here once thats taken place

Yea, I would try some other towers. If that doesn't work then I would try going back to the original spl, radio, and rom and see if 3g works then. It would really blow goats if that was the case, and I would brick the phone or something to get a replacement because 3g should work no matter what seeing as how it is a hardware thing. Maybe try a few different romslike cyanogen cuz I know people who use it and still get 3g.

Wont that brick the phone? I heard that going back to old radios is a no-no.

I beleive if you do it in the right order it should be ok but I could be wrong, try searching around. If not I would atleast try using a tmobile rom. I looked around on google and didn't find any info on this problem so I really think it is either a rom problem or something with the towers, I don't see how flashing anything would affect your 3g band or stopping the phone from using it.

If your gonna do this, flash the DREAIMG.nbh file from the original rooting process

F YOU HAVE THE NEW SPLE FROM HAYKURO.. DO NOT FLASH DREAIMG.NBH FILE IT WILL ALSO INSTALL THE OLD RADIO AND THUS WILL BRICK YOUR PHONE.........
It is an easy fix though... just Re-Flash the HardSPLhttp://koushikdutta.blurryfox.com/G1...SPL/update.zip
Do that ^^^^^^ and you can re-Flash the DREAIMG.nbh (RC29) image with no problems

I did alot of searching and this is what I found, so if your still having the problem then this is how I would go back to the original rom. If you just flash back to RC29 DREAIMG.nbh without switching the SPL first then you will brick because RC29 flashes the old radio back along with the rom. Something else I thought of trying would be if your significant other has a 3G capable phone try holding the both in the same place and see if they get different reception (3G/E).

I spent some time driving around - no 3g connectivity at all.
So the consensus is to flash all the way back to rc29 and go that route?
also, that url that was linked above was shortened - anybody got the full one?

Thanks for the tip but tried it ten times didn't work for me. Tried full wipe and really flashing but still don't get it

Same issue here. I notice if I force it to Edge then Edge works, but no 3G after 5.0.5.3 and i flashed the EPE54B radio with the apps. I'm thinking it's the radio but i can't find the previous image to test it out...

I have the same issue after flash CM5.05.3 and radio EPE54B.
It can't use airplan mode to solve the problem, only reboot.
Does any sollution? Help !!

After trying a million things my sister tells me her mytocuh is having the same issue. I called T-Mobile and they don't know crap. It just now started working again for me almost a day later out of the blue.

Yea I still for nothing no edge or roams mg data just got calling network irk what it is so guess just deal with it. Closest city with 3g to me is 40mi lol

Sounds like a problems with T-Mobile and not the ROM. Make sure you have "Allot data connection while roaming" checked also or you'll never have data while roaming

JK3 modem, loss of all reception, drains battery, requires a reboot

So, right now I am using the Axura RC1 CE (I will update later), but I have had the problem described in the topic on various other ROMs using the JK3 modem.
It works fine for a few days (time is random, I have not been able to manually reproduce the issue), then randomly I lose all reception. Switching to flight mode fails, it gives no error, it just does nothing, in the notification bar it just says (searching). I have to reboot the phone to get the phone functioning again.
Anyone else experiencing this on ATTs network, or if there is a fix, I spent the last hour searching and going through the various threads to no avail (or I just suck at searching)..

Did you try the Axura thread?

I'm having the same issue but I've tried Assonance as well and still get the random no service. Tried different i9000 modems as well--anyone know if its safe to use a captivate modem??? I'm guessing no but just want to know if anyone has tried it without borking the phone.

I'm having this same issue as well, that's why I've tried to stay away from the UGJK3 modem, however, it's seems every custom ROM is starting to use it
As far as using a captivate modem with an i9000 ROM, I've tried that also, while it didn't totally brick my phone, I did get random FCs. I've read that is a dangerous path to go down.

I feel the same way. I might try the CogKernel and see if that helps...

Please, please, PLEASE do not post these types of things in Development.

+1 Lets keep this forum area clean .. its just for development stuff guys.

I have had the same issue with all I9000 modems, the only fix that has worked for me is to enter the service menu and force WCDMA 850 Band only. Also, questions should be posted in the question forum.

[this thread is pretty relevant to development - considering the rom chefs are using this modem in their releases and it has a potential major flaw. if the mods find it better to be in Q&A, then please move it - otherwise, i think the right eyes will see it here]
yes, yes and yes!
ive been posting about it in the perception thread, but no one (save for 1 user) chimed in with the same issue.
we both noticed that we both have an issue where we will bounce from 3G to H and back fairly often. this leads me to believe that it could be part of the problem.
i just odin'ed back to stock because my phone isnt receiving incoming calls now.
what i had planned to do was flash the latest perception but use a different modem... but it seems like the only sensible modem is the JK3 (although there is word on the street a new one just leaked?). so that idea is kind of out.
someone here said they were going to try cogkernel2, but i was on setirons and cogkernel2 and it happened with both. it seems to be a modem issue.
i wanted to lock the phone to use 3G only to see if that would help, but no one shared a way how... but reading this post it seems i can do it from the service menu - though i dont know exactly what to set/change to keep it only on 3G. (any help would be great).
so i believe im going to flash perception 8 and see if i can lock it into 3g mode and go from there. this is getting pretty tiring. im hoping if a new modem releases that will help, but i honestly am not sure i can wait since it is making the phone unusable.
below are my posts from the perception thread on the issue.

i searched but did not find...
i see others have had issues with APN force closing. i do as well, but assuming that isnt a problem, i dont mind.
my issue is that after a certain period of time left asleep, my phone will completely fall off the network. changing flight and data mode dont work, nor help. a restart works. this has started a day or two ago, but was not an issue for the first week (give or take). if it is relevant, my network constantly swaps between H and 3G where i live.
i have not found a setting to force 3g (and disable hsdpa) as i figured it was the network hopping that was doing it. am i just missing that setting? anyone else with this issue? (again, i saw people with the apn force close but not complete loss of network unrelated to initial flash)
also, i think that each build should get its own thread. it is VERY difficult to find accurate information on the current build once a thread has 4 builds and 250 pages in it. even with search, it would still be a good idea.
thanks and thanks.

of note: going into wifi settings is also borked. it will eventually time out and FC. i also think that the times my phone has completely lost network and not reconnected have happened more often when charging. but that could be coincidence.

this continued the same way on perception7 with cogkernel2. no real difference.

in relation to my post below yours, does locking the 850 band only force the phone to use only 3G, or is HSDPA/HSUPA still enabled but you found the 850 band to be more stable.
this is what my next attempt will be to get a solid platform going.

I've tried different modems other than jk3 and it doesn't fix the problem. Stinks that you've used Cogkernel2 and it doesn't help. I also tried the different band selection in service mode and it also hasn't help me (apparently this worked for some people). If you want to give it a shot do the following:
1. Dial *#0011#
2. menu button then soft back key
3. then phone control -> network control -> band selection
4. good luck!

ugh. that is disheartening. i will try the band lock, thanks.
can you confirm or deny that when you notice your phone goes completely out of service that it has been hopping between 3G and H? it would be interesting to see if we all have that issue as part of it.
also, fingers crossed for that supposed new modem.
/sigh

Yeah this really sucks because these roms are great with this one very big exception. I haven't noticed the hoping before I need to reboot. I have noticed that if I switch into airplane mode once I drop service I can't turn it off.

I had the same issues with Axura and Percetion. I found that switching my network control to WCDMA 1900 only pretty much fixed it. The only problem I had after was that any time I lost service naturally, ie, bad area, or shielded rooms, whenever I came back into a good service area I could never get a signal again. So I would have to reboot.
In the end, I'm back on Cog, 2.3b7 and no issues for about 14 hours now.

I'm using the non oc. I'm not gaming or doing anything too wild with my phone so non is just fine for me.

hmmm, makes me think that's the issue then. most of these roms have kernels that have the oc feature.

hey keener, did you have the oc version of cog?

[Q] Wi-Fi To 3G

Hi,
Got a really annoying issue with my Nexus One that has been happening since the Froyo days, when I leave home to go to work I turn the Wi-Fi off on my phone to save battery. Sometimes I use the widget sometimes I go through the settings.
The problem is that the 3G doesn't alway's kick in, the only way for me to get 3G working is to turn my phone off and on which always works.
Any suggestions on why this is happening and how to resolve them?
I am running Stock Ginger Bread on my Nexus One on the the Vodafone network in the UK.

Try checking your signal strength: *#*#4636#*#*
You can try to enable 3G only and see if you can keep a signal.
My signal is sometimes intermittent due to topography. Stupid flat Ohio. Haha

Thanks, it won't be that though because once I turn the phone off then back on it's there. Also once I turn W-Fi off and 3G doesn't kick in, then it won't do untill I restart. Also another reason why I know this isn't the case is because even when I do this at work 3G doesn't kick in and there is a Vodafone 3G mast on the roof

never seen this problem before, but it sounds like something that might have to be fixed by doing a full wipe and reflashing your ROM. i know its drastic, so maybe do a nand backup first. then flash and see if the problem remains. if its still there, than just go right back to your backup and no harm and nothing lost. worth a shot.

I'm on a stock Nexus One unrooted so I shouldn't have to Root to fix an Android problem. Never Rooted before but considering it.

I got the exact same problem with Froyo and Gingerbread ROMs, can't remember if I had that issue with MIUI ROMs, but definitely with CyanogenMod ROMs.
Instead of rebooting the phone I suggest switching flight mode on/off it's faster than a full reboot
Haven't found any real solution yet and always thought I'm teh only one with that problem as I couldn't find any other person with that issue. Right now I'm testing different Radio/ROM combination and if that doesn't work I'll need to check if any app is causing the problem.
Any chance you are using Tasker?

[Q] When I turn wifi off, Note does not connect to 3G or HSDPA

Hi guys,
I have this strange problem, it even seems random.
After I turn wifi off, my Note does not connect to 3g anymore.
And I have to reboot the phone to get it working again.
Does anyone experience the same problem, or knows a sollution?
I rooted KK1 and flashed LA4 using Mobile Odin.
Cheers,
Daan

I've had this problem once, but it worked again after a reboot. Haven't experienced it again. It happened on KK5, but i flashed LA4 yesterday, so it's too early to tell if it will happen again.
It also happened on my Desire HD with MIUI and also while running CM7, so it might turn out to be a bug in Android.

I guess you had turned/switched off data network mode by pressing and holding the turn off button for two seconds.
Try and turn it off and see if it is the same symptom that you had before.

No, this is not the issue.

I manually set the APN settings for Telfort, removing MMS and setting it up for "internet" only.
Did a wifi on/off cycle, with a short interval and it seems to work.
Going to test with a longer interval. Not completely convinced yet.
Hope it's fixed.
---------------
edit: Not fixed!
On wifi for half an hour, turned it off and [email protected]#$% 3g does not connect anymore.
Maybe it's just Telfort. They don't have the Note listed on their website, but still.

My infuse 4g does this. I have to put it in airplane mode then back to get my data to reconnect. It did this stock and on serindipity 7. I couldn't find a fix either.

Annoying stuff! Cycling airplane mode does not work for me, only a full reboot.
But if you had the problem too, It could be that it's the network's (in my case Telfort's) problem.
Maybe I have to get my sim replaced, but I'm switching to T-Mobile in about a month.
So it's a bit of a pain.

I am currently using the infuse on o2 in Germany, but it did it on att in the states also. I can't wait to get my note. I am just waiting for it to be released on o2 over here. They have the black but I really want a white one.

Telfort used to be O2, it has been using KPN's network for a while now.
So it's probably not connected. Though it is a strange coincidence.
I'm off today, I think I'll walk by the Telfort store to ask for a new sim or something.
Maybe they'll have to flip a switch somewhere.

Yeah you're right, I have to troubleshoot properly. But it's such a pain
And I think I recall having this problem a few roms back as well.
I'm not sure because I was on wifi all the time.
But I have to wipe, I'll use titanium backup so it won't be such a hard blow
Man I'm going to pissed if it turns out to be the network

Thats a pain i was so tired of formating,..reformatting....coz many custom firmware have some error and new updates keep coming almost daily...and all ask to wipe for best experience..dat was when i finally decided to come bk to stock and stick to it...
yeah it doesnt hav those fancy colors and throbbing speed which a custom rom boosts about but...but hey everythin works flawlessly and i dnt have any tension of random reboots and alarm not ringing..or any smartphone related error to comeup...plus all my apps and schedule is there forever no reinstalling tension....enjoying my phone....

Okay, so I I did a full wipe and installed a deodexed rooted LA4.
I still have this issue.
Also tested on KK1 stock and still experienced this issue.
If it does this on KK1 and LA4 it's reason enough for me to believe it's the network.
I'll just wait for my T-Mobile plan to start. Meh.
edit: It seems to work just fine on CM9 :-/
