Stuck on Edge (2g) - G2 and Desire Z Q&A, Help & Troubleshooting

Today I noticed that one of my G2s was stuck on 2G and so I thought maybe I had reached my 5gb limit but then I switched SIM cards and I know it hasn't reached anywhere near the 5gb limit. I also switched SIMs and put it in another one of my G2s and I have H and 3g. I restarted the phone that has been stuck in 2G and it was still stuck I restored a rom that I had installed a few days before (H and 3G were working on it) and it was still stuck on 2G so I wiped it and reinstalled cm6.1.1 and it's still stuck in 2G.
Any ideas?

Did you make sure that you don't have use only 2G networks in the settings?

yes I did and I also use superpower but I checked it and after wiping it just remains in 2G so I don't think superpower could be doing it. I'm lost not sure what else to try I've just put Enom's new rom it and it's still stuck on Edge. While my other G2 is sitting right next to it pulling H while I tether my laptop to it while I'm at work.

Try dialing *#*#4636#*#* then go to phone info. and change the preferred network type. I think it's supposed to be on WCDMA preferred, but you could put it to WCDMA only if you want, that's how I have mine.

Wow it worked I've never tried that before how does it affect battery life?
Thanks for the help.

I just set it to that a couple of hours ago so I don't really know how it affects the battery. I thought I had it on but I guess it changed from when I tried out a Sense ROM then went back to CM.
Glad I helped.

[Q] Signal problems at my DHD

Hello guys,
I need some help here with my DHD. My serious problem is about its signal. I am in my home and i am talking on my DHD, but sometimes it loses the signal. In my house, the signal is very good, not always at 3G but at 2G it is always at full signal.. Although, it sometimes loses its signal and my call is closing.. By the way, to be more clear, when my call is closing i check the signal, and i see it to be full... At this step, when i am checking about the signal, sometimes i see the signal to drop down to zero, after 1-2sec.. But the other times it stays full.. But in both of these cases, my call is closing many times.. What can i do to solve this problem, anyone knows?
Thanks, and i hope to help me with this.
P.S. Sorry for my bad english guys And one more problem that i have is that my DHD few times, it lags, stucks, dont know how to say it, and in first case it unstucks afters 30-40 sec, or in second case it restarts..
AFAIK, the gsm antenna is located in the bottom cover that the sim and microsd is hidden behind. If the contacts inside dont make a good connection you will probably get lost reception from time to time. You could try another cover, or bend the two gold coated spring contacts near the simcard very slightly outwards to make the connection more reliable.

I tryed it mate, and tnx for your reply. But today in the morning, when i was talking on the phone, my call closed 4-5 times in a 20min call.. Dont know what is happening, but maybe anyone of you guys knows another tip to help me? Maybe any change on the software? And by the way, my phone had in automatic the choice about 2G/3G, but i changed it some days ago only to 2G because in my house the 3G signal is not so good always, and if it loses the 3G signal and it needs to change to 2G, the call is closing for sure..
I have the same problem with my DHD, I live in an area where the 3G signal is crap. I found that when running CM7 you can switch off the 3G and just use the 2G which helps. If you using a sense ROM you don't get that option which is a pain, so I'm sticking with CM7 for the time being until someone produces a workaround for the other ROM's.

You can swith off the 3g in Sense ROMs, press Menu > Settings > Wireless & Networks > Mobile Networks > Network Mode change to GSM Only not GSM/WDMA Auto (WCMDA is 3g)

Try your sim in another phone. If the signal is still bad you should try contacting your network operator and ask them if there are any faults or if they can do anything to improve your signal.

No sense is like CM7 (Cyanogen Mod 7). They are as close to standard google android with added features. Standrard android is found on googles own devices like Nexus and Nexus S. Although CM7 is based on AOSP (google it). Sense has a different (rosie) launcher and added extras included such as widgets, Icons, and other extra HTC only features. Look in the Desire HD andorid development thread for different ROMS with sense no sense.

I was using some times another phone but i didnt have this problem same as i have it on my DHD. Yeah, maybe i had it few times on my other phone but occasionally, and not so many times like these on my DHD.
I had the same problem. I had to order a new sim because my sim card was old and apparently wasnt very compatible with my DHD. I'd suggest getting a new sim from your service provider
Hmm leaked from my thumbs through my mobile device....

Sent from my R800a using XDA App
mine has a glitch where it switches the network it's assigned to by itself. Rogers shows up as two networks, one edge and one 3g/hspa, and I noticed if my reception is bad at a certain location it will sometimes switch to edge only, and not turn back. It's only been doing this after the update to 2.3.4
Edit/update: I figured out you can force the phone to never use edge, if you change it from wcdma preferred/gsm to only wcdma

Odd data problem

Ok so I have an unlocked LG Nitro HD with custom ROM (CM10) and it has a very weird problem. I've tried two different AT&T MVNO SIM cards (AirVoice and Consumer Cellular) both have the same issue. My data signal keeps changing from H to H+ and occasionally to 3G like every few seconds regardless of where I am using the phone even outside. I don't understand what the problem is. What could be the issue?

Data does work but it seems to drain the battery with the networks constantly switching and on occasion I get a "No Connection" screen on certain apps, I guess because if I open an app while its swapping networks the app cant connect. It's strange.

I had another odd problem, just a few minutes ago was texting someone and all of a sudden phone froze while vibrating then restarted! Don't know if that's a bug in CM10 or what, maybe the network swapping is as well.

I tried installing CM9 and it appears to have fixed the problem, the phone doesn't try to connect to the H+ network anymore, only the H network and seems to stay on it so far. I did see it quickly go over to the 3G network but it doesn't appear to be causing any issues, it went right back to the H network. However, I really wish the CM10 ROM worked right, as CM9 is so old...

CM10 is snappy and oh so buttery smooth, I give you that. On another note, did you try any other CM10 variants? I'd give tdmcode's AOKP a spin. He says he might have fixed that problem you were talking about in his build.

I downloaded the CM10 ROM. It seems to behave slightly differently. It stays on H normally, but when I start to do something with data, it will go to H+ until the data loads, then go back to H. So far no disconnects, I'll keep you posted. Right now I have very limited data, I'm switching to T-Mobile as soon as UPS decides to deliver my SIM card (just found out they have a 1900MHz HSPA+ network in my area!) I'll be able to test it better then, but for now I'm trying to stick to wifi, especially since I wasted so much data tonight playing around with this stuff, lol.

Ditto... H and 3g are subsets of each other. Namely they can handle simultaneous voice and data 4G (h+) and lte can only handle data. So it switches back to H so you can receive and make calls plus it uses less battery. If you are on either 4G techs and receive a phone call while downloading it will automatically switch to H from h+ or lte, this is why. The only way you will never see this is on an AT&T rom where it only has 4G and lte icons.

H+ isn't a subset of 4G is it? I know that the CM's have separate icons for 3G/H, H+, 4G, and LTE.

That certainly is debatable but the US's largest carrier considers it to be, it behaves like 4g, H+ may not be as fast but it is 90%+ as fast in most markets small enough to not make a noticeable difference as far as people's perception and the technology behaves like LTE in a lot of respects, CM is international so it just conforms to International norms so that's why you get H+ AND 4G (LTE) designators.

No LTE after rom install

I have a S3 i747 and have tried several different roms and always lose my LTE. After install it jumps back and forth between H+ and 3g it never stays on one. I have tried installing LTE fix and it does not fix problem. I also tried manually entering correct ATT setting but still nothing. I tried speedtest after to see what my speeds where and H+ is around 3mb download and 3g is around 500kb download. please can anyone help

Yeah that happens when going back to a tw rom from an aokp. What you have to do is backup your current rom, restore a backup of your stock rom once you're in there go to more settings you should find the option for lte in there choose it wait for it to connect and once you're connected just restore you're rom and you should have lte.

This is slightly different than the guide posted above and has worked for me every time.
Go into your phone dialer. Enter *#*#4636#*#*. Go to phone information, and find the drop down menu. Select "LTE only". This should force LTE. Then you can select LTE/... Whatever one you want, and it should start connecting to LTE by default. If it didn't work, then LTE is unavailable to your phone for whatever reason.

So if i am not in a LTE area will i still have 4g cause right now it bounces between H+ and 3g. it does not hold H+ very long then goes to 3g for few minutes then back and forth and download speeds are crap. I was getting .22MB.

If you are not in an LTE zone, you cannot connect to it. If your phone says "4G", it is referring to LTE. "H+" refers to HSPA+ which is more accurately 3.5G. If your phone is switching between H+ and 3G, it may just be corresponding with your data activity, where H+ is active and 3G is inactive. It may also be because of poor connection, which could too be why you're getting bad download speeds.

[GUIDE] [HOW TO] Fix VS986 dropping down to 3G/H+ from 4G LTE

I've been working on a fix since a long time now. If you are in SD community then you prolly know me. Anyway I was able to fix this on two of my phones and it's working fine. I tested for 12 hours now. I'll also tell you in the end what problems I'm seeing. I'm also working on a fix for that.
I noticed that a service is started when the fallback happens but if I kill that service the network also dies. But if you follow the below method it safely starts a new service which kills the one that's responsible for killing the 4G/LTE
1. Upgrade your phone to 13B firmware
2. Root 13B
3. Now download Shortcut Master lite app from play store.
4. Now add these shortcuts to your favorites in the "Shortcut Master lite app". You can search for "LTE" and click on search button
LTEBandSelection
LTETestMain
LTE System Selection
CDMAPreference
5. Now click on "LTEBandSelection" and enable all the bands
6. Save and reboot
7. You now need to enable your data and turn off your wifi. Make sure your phone is in Global mode (in settings >> Mobile networks >> System select)
8. After your phone is rebooted open "Shortcut Master lite" app.
9. Now tap on LTETestMain
10. Select Click on CDMA preference.
Now choose Band preference and select "any"
P_REV_Preference ---> "MOB_P_REV 3
This is important.. EVDO Revision --> Rev A
11. "LTE Connect w/o IMS PDN" must be checked
12. Now go back to your main menu in shortcut master lit app
13. This step is very important. Changing the timeout is important. Tap on LTE System Selection
Except "Scan duration" add a couple zeros to all the other timers. For eg: T_mpsr timer (Min) is 200
The fallback timer will reset itself after reboot. But don't worry the configuration is already updated with the new value. For some reasons the shortcut master lite app is not picking it up.
14. Now finally click on "CDMA preference" in the main menu and make sure it has the value you set in Step 10
At step 10 or 13 your network should go away and your phone should complain about "no network". That's fine. just ignore the message.
Now finally reboot your phone. That's it. You should now have 4G LTE and it won't fallback to 3G or H+
The only problem is when I'm on a call my 4G LTE is dropped to 3G/H+. But after I hang up it goes back to 4G LTE after 12 seconds. I don't know if it's an expected behavior. But I'm trying to see if there is a fix for that.
I tested this with Tmobile. Make sure your APN settings are correct.

Awesome, thank you! worked for me T-mobile.
it initially didn't work but I had to turn data off then on.
It also cycles me to 2g speed for a few seconds sometimes but that may be due to poor signal in building.

Yeah It's due to the poor signal. I got that too. You can check your signal strength using LTE discover app.
But overall it's working fine for Tmobile. I'm gonna try and fix ATT tonight.
Is 13B the main thing in the solution? I've changed these settings before on 11A and wasn't fixed. I tried these numbers on 11A and still don't work.
Also, unless a phone supports VOLTE, it'll fall back to 3G/H for calls.

I tried in 11A and it didn't work for me. So I guess it needs 13B.
So I tried various combinations last night for AT&T/Cricket, but I was not able to get it to work. No matter what I tried, when I had 4G LTE, voice wouldn't work and whenever voice worked, I was back to H+.
If others are reporting that T-Mobile works reliably on 4G and nobody can figure out how to make this work for AT&T, I guess it's time to switch to T-Mobile.

So I tried various combinations last night for AT&T/Cricket, but I was not able to get it to work. No matter what I tried, when I had 4G LTE, voice wouldn't work and whenever voice worked, I was back to H+.

No. Hold on. I have a solution for ATT too. I tried something last night. Actually while I was working on a solution for ATT I found that we don't even have to go through the steps I mentioned in my OP to solve the problem. It boils down to invoking a service and killing a native VZW service.
The ATT solution I have works but in low signal area 4G fades and it doesn't fallback to 3G or H+. I had to recycle data to get 3G or H+.
It's Working!!!!!!!!! Thank you!!!!!!!
You just made my life much better now!
I finally have a phone which is great and also finally have good reception!
I Love U!

Yes, that same thing happens when you switch to CDMA mode with AT&T. Voice doesn't work then (obviously), but it also doesn't fall back to H+ automatically, when you lose 4G coverage you pretty much lose signal all together.

Yeah I know. I also know why that is happening. Actually I think it's a bug in the baseband firmware. But we can fix that issue by just overriding the command that was sent by baseband firmware.

Do you have a working fix for AT&T/Cricket? Is it different than the T-Mobile?

Ha! You are repped!
What root did you use? and steps?
easyroot?
did you split the file and merge it back?
I must have really bad luck or something. It doesn't work for me. The Tbsr_cdma timer resets back to 2 at reboot.
Edit: Appears to be working. Nice job!

Root? I just flashed the rooted sys image. That's it. instead of copying it in the FAT32 memory card just copy it to your phone's internal and you don't have to deal with split and merge stuff
If it drops out of 4G on a call then you're talking on 1X. So no video chat, no HD voice and no voice + data?
