CM7 on D2G - issues with APNs, possibly Rogers specifically?

I'm posting this on the four android-related forums that I participate in, in hopes that someone has seen this before and knows what to do.
Here's what I had:
- Droid 2 Global, unlocked, rooted, with Fission ROM, using Rogers Wireless, a GSM network in Canada
- it had been working just fine for 5 months
Here's what I did:
- Used RSDLite and the SBF loader to flash the stock 2.4.330 firmware as seen here: http://droid.koumakan.jp/wiki/SBF
- ended up with a bootloop, as the directions said I would. cleared data and cashe, no problem, phone booted.
- started up phone, switched to GSM mode, entered APNs, immediately had data service, tested phone functionality, all was well, used APN backup/restore and APN Manager to make backup files of my APNs
- Used stock recovery mode to upgrade to 4.5.607 (gingerbread) firmware as seen here: http://droid.koumakan.jp/wiki/4.5.607_Firmware
- I used the file linked to from here: http://www.droid-life.com/2011/08/22/gingerbread-build-for-the-droid2-global-leaks/
- started up phone, switched to GSM mode, entered APNs, immediately had data service, tested phone functionality, all was well, used APN backup/restore and APN Manager to make backup files of my APNs
- rooted phone using the adb method that is out there. rebooted and confirmed root access. installed a couple apps that need root. tested phone functionality, all was well. used APN backup/restore and APN Manager to make backup files of my APNs
- As described here, http://droid.koumakan.jp/wiki/CyanogenMod Installed Droid 2 Recovery Bootstrap and ROM Manager in order to flash CWM. rebooted into CWM, factory reset, installed the latest release (10/06), and rebooted
- started up phone, switched to GSM mode, phone app crashed immediately (as is to be expected, based on known bugs), rebooted for it to take effect
Now here's the problem:
- phone can make calls and receive texts with no problem, but cannot get data. wifi also works.
- went into wireless settings, mobile networks, access point names, nothing shows up. Clicked "add APN". entered the APN info that had worked for me before at the past two junctions. hit menu button, then save. takes me back to the APN screen, but no APN shows up.
- repeated this cycle a few times following reboots, etc. Eventually the phone gets to the point where the "add APN" button will not even come up when the menu key is hit.
- during the above, was also checking the "network operators" setting. The phone does locate all of the networks that are "in the air" but no matter which one I choose it will tell me "your sim card does not allow a connection to this network"
- used root explorer to check /data/data/com.android.providers.telephony/databases/telephony.db. There is a list of about 1500 APNs. There are multiple entries for Rogers including all of the ones I tried to enter that appeared not to save.
- used APN backup/restore and APN manager to attempt deleting existing APNs, restoring the ones that were known to work, etc. Nothing works. These programs do work, and when I check the telephony.db file I can see what they have done to the file, but they are unfortnately unable to make any APN "stick" at the APN screen, and apparently that is the only way that it will work.
more info:
- I've noticed that the list of rogers entries seems to get larger and larger as I go through this process multiple times. I may be wrong, but it seems that this telephony.db file might not actually get changed or updated when you flash a new kernel/firmware/mod/rom to the phone.
- I'm sure that the lack of a list of APNs and the "sim card does not allow connection" message are related. For whatever reason there seems to be a bug in CM7 where the telephony.db file has problems "talking" to the APN screen in settings. But it must not affect most people.
- yes, I have tried a new SIM card.
- yes, I have tried clearing cache, data, dalvik, and fixing permissions.
- Anyone else on Rogers Running CM7 on a D2G? If so, I'd love to talk to you. Maybe I could convince you to send me a working CWM backup. I imagine that if you're a conscientious rommer, you have a backup made folling a fresh install of CM7.

I used to do at one point. The froyo base 2011.08.13 version was the last one that worked for me. Newer ones boot looped if SIM card is inside, no matter what I do. I stopped trying after couple further releases all of which boot looped. Essentially quit using CM4D2G due to bluetooth not working with BT handsfree. Later, after the official Motorola GB release came, I have not even looked back. Since I like few BLUR features, especially dialler, the GB Motorola released suits me very well. With the doubled battery life and the MUCH BETTER GSM radio in 606/607 bulds, phone finally settled down and I can now rely on it.
I have CM7 on another of my phones - actually 2 of them - a Milestone and (recently) a HTC Vision - I love CM7.1 especially on the latter!
I assume your phone works fine with stock rom - right?
Edit: I have a XT860 which is in for repairs - once I get it back and I have a reliable daily phone I plan to experiment with the new GB based CM4D2G. Hopefully this week...

Yes, everything works really well with stock rom. I was quite impressed, as it was my first GB experience. Unfortunately, as with cars, I am all about the "options", and I can't seem to let go of a feature once I have experienced it. I love CM7 and I really want to make it work for my D2G.
I posted this same thing at the rootzwiki thread, and one of the head developers said "You my friend may finally have identified where the gsm data issues are coming from. it isnt just you, it's 98% of the gsm users that arent having data". Another user got me to change a couple of permissions. I thought he was onto something but it didn't work, either. Nonetheless, I think I brought enough attention to this issue and also gave them something to work with through all my trial and error. I am optimistic.
But, for now, I think I have to take CM7. I want my data! I am really tempted to just give stock GB a shot. But Blur scares me. Most people don't seem to like it, though I admit I don't fully understand what Blur is! I see there is MIUI and apex, angel Hexen and VenusX. I might have to try them first.

hallo!
had exactly the same problem! i bought a verizon phone an using it in greece!
But i simply dowloaded some APNs manager from the market and within 2 minutes my phone was connecting to the internet!! So if this worked for me i`m sure its gonna work for u too!!

Can you be more specific as to what you did? Because it sounds exactly like something I tried already. What was the exact name of the software you used? Was your problem 100% exactly the same as mine, or just similar? I literally can't make an APN show up at the APN screen at all.

Some people have this exact problem with the D3, looks like in the D3 placing the phone in airplane mode and then on again is enough to make the APN manager able to read the MCC/MNC codes and, consequently, to store the provided apn.

I wish it was that easy, but it's not. I have tried a number of solutions similar to that but no dice. I appreciate the attempt though.

For the record I have that problem on the D2g flashed with the latest builds of cyanogen rom, (with the same SIMs perfectly working on D3 and D2g with the stock rom), and the airplane mode trick doesn't works too.
So far I haven't found a solution

To get my wife's d2g to work in japan I had to use root explorer to manually edit a file. The file is located at etc/ppp/peers/pppd-ril.options mount the file rw and manually edit the user name and password to match your apn. Toggle airplane mode on off after saving changes and it should work.

Thanks, i guessed that if a proper fix may be hard to find, a workaround was easy enough, I'll try it later with the gingerbread froyo.

sounds interesting. I will give that a try the next time I flash CM7. I moved on to Apex. It's ok, but absolutely dreadful for battery life. I can't imagine CM7 is any better considering it has about 50 more bells and 125 more whistles. But I do prefer CM7 to anything else so as soon as I actually have some tweaking time again, I'll give this a shot.
Since both CM7 and Apex are built off the same firmware, I could just flash them overtop eachother, and wipe date and cache, right? As long as it's that easy, I could see myself trying this sooner.

I now own a D3. CM9 is doing the exact same thing to me!
I tried what you said and I am still not getting data. phone and texts work though, just like before.

[Q] MW 4.3 - Data connection misbehaviou

Dear All,
it is about a month I am happly using Mildwild 4.3 (Oxy). Quick,no memory hangry and battery last quite enough not to bring my charger along side.
But...there is always a but, I have a small list of issues/questions I would like you to have a look at and maybe give me some heads up:
(listed in order of importance ..for me)
1) Data connection - I go to Wireless & Network settings --> Mobile Networks -- > Data enable I select it. Sometime the effect is the desired one: my data conntection switchs on and I am on the network. Unfortunately 8 times out 10 nothing happen. The workarounds I have found are the following a) Switch to 2G -> 3G (or the other way around). b) go Airplane mode and then go back to normal. c) Let the gsm reconnect on the GSM network
Any idea what s happening? Is it a known bug?
2) Incoming call - The main reason why I migrate from MildWild 5.0 CM to Mildwild 4.3 Oxy is because on incoming call I had a delay in the conversation, basicaly the first 2 seconds were mute. With this rom looks like the 2 seconds freeze period have migrated to the screen. Basically on incoming call for the first 1 or 2 seconds my screen stays black and I cannot neither answer nor hang up. Really annoying expecially if I forgot to put it on silent and I find myself in a middle of a meeting. What I really miss from the original HTC desire OS is the flip functionaly capable to mute the phone flipping it face down.
3) New release - Does anyone knows when a new release will be available? (4.4??...)
Well that s all my androians. I am looking forward to receive your feedback
Ciao
Stefano

Hey folks! Anyone has suggestion (expecially for my point 1) ??

I've seen behaviour a bit like this with MW 4.3, I think it was because it didn't have the right APN settings for my network. I looked up the right settings and created two new APNs, and my phone is behaving better now.
It seems like MW 4.3 has a limited range of network settings, eg. here in Germany it lists the main networks but not all the MVNOs (resellers).

4.4 is out this week: http://forum.xda-developers.com/showthread.php?t=1353861
However it won't boot on my Desire (PVT4), despite a full factory-reset and wipe. It just sits there on the boot screen until the battery runs out, so I'm back on 4.3 for now. And I'm caught in the "you have't posted 10 times yet so you can't post in the main thread" trap, so I can't report it in the most obvious place.
Cheers m'dears,
Bryan

Hi Bryan,
I could not resolve the connection problem. my parameter are ok. I made few more identical APN (just to give it a try) but with no benefit.
On the other hand I have just downloaded the 4.4 installed on top of the 4.3 (no wipe) and apparently it s working fine (could not no major improvement so far)
Cheers
Stefano

Thanks, maybe I'll try 4.4 on my other Desire (a PVT1, I think) just to see if it works there.
This wouldn't be the first time I've had odd behaviour from the PVT4, by the way - its GPS wouldn't work under Mildwild-CM5, whereas earlier models were fine.

Intermittent Data/Cell -Exclamation Mark in Signal Indicator

This happens on every Lollipop ROM I have flashed, no problems on 4.4 ROMS. I do clean installs, do not restore anything from Tibackup. So basically what happens is I will randomly but very frequently lose all data and cell service. Like once every three minutes frequently. It only lasts about 5 seconds at a time. The signal bar triangle will have an exclamation mark in it (see attached example). I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option. I have read some threads about this exact same thing happening on Nexus 5 after Lollipop update but they are old and it seems to have been fixed with an update. Does anyone have any ideas about what is going on? I'm on TMO in the US and like I said, it ONLY happens on Lollipop ROMs it does not happen of Kitkat.
I read this as sort of an explanation as to why but nothing as to how to fix it. It is driving me insane.

I'm in the same boat, I cant make calls with hangouts or with Dialer or it will disconnect. I haven't seen a solution yet. I've tried every ROM I can, but it keeps crashing. drives me up a wall. I want to logcat it, but having issues while at work.

Only discussion about this I have seen is in the Nexus 5 forums, nothing in OPO

Any insight to this would be greatly appreciated.

Come on guys, am I really the only one with this issue?

You're not alone, I have this as well but I don't get the exclamation mark but instead the triangle appears completely empty, as if I have no signal at all.

anyone know a way to fix this awell? i flashed the new lolipop alpha modem and still same thing if not worse

The only time this has happened to me is when I toggle Wi-Fi. It for this every time, but have no data issues otherwise. Seems to be when switching between ip addresses. Are you possibly between towers or roaming on another network? May be the issue, but I can't say for sure. Running the lollipop rom exodus, no issues at all.
EDIT: also what baseband are you guys on? I thought I saw something similar and someone flashed a test baseband and it fixed whatever issue they were having. Link coming shortly.
EDIT 2: just now noticed the list above mine about the alpha modem and it not working for them. If anyone else needs to try however, link is http://forum.xda-developers.com/sho... work for some and not others.

Does anyone know if we can flash the CM11S modem on CM12?

Go to Settings -> More - > Mobile Networks. Make sure all the items are set correctly.

In OP "I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option."

Same issue here. Running SlimSaber using alpha radio.

Same problem on two OPOs here, both running Temasek CM12

Anyone found a solution yet?
I have the same issue on CM12, BlissPop and Validus ROMS.
Strangely I do NOT have the issue on Euphoria.
Think it happened after I flashed the Alpha L modem.
Tried flashing an older CM11S modem, but no luck...

Hi,
Sorry for the noob answer but anybody tried settings>mobile networks>preferred network type and set it to 3G? I flashed a new rom from stock CM and noticed that I was experiencing signal trouble, I checked my status and the signal detected is LTE so I changed my network to 3G and network signal improved. Downside is that you cant use LTE (but thats ok for me since here in our country, LTE signal is still kind of limited)

Zino same for me. Ever find a fix or a rom that doesn't do this?

OP here, it's strange that all of us have this issue, the same issue that came up on the Nexus 5 thread when L was first released but know one else seems to have any knowledge of it. I am almost certain it doesn't have to do with our carriers but rather something software related.

I'm also suffering from this issue, until now the only way I knew how to fix it was to wipe the cache in recovery which takes ages!

got the same problem :<

I have a similar issue. I use t mobile in the USA and LTE works, H+ works, but 3g shows signal and won't load anything. No idea how to fix it.

I'm Roaming... OR AM I?!

Having a weird issue with a custom ROM I'm trying to install. I've got a Xiaomi Mi Mix 3 and I'm trying to load an unofficial version of Pixel Experience. It hasn't been a totally smooth ride, as I need to pre-load a Xiaomi ROM before I can load PE and it took some trial and error, but I got there (see here https://forum.xda-developers.com/mi-mix-3/development/rom-unofficial-pixel-experience-p-t3882080 - I spent many hours today reading every comment to see if anyone else had my issue; they don't).
So far, everything is smooth and working as expected, EXCEPT the mobile data thinks I'm roaming. I'm not. I'm in Austria with my Austrian SIM. On the mobile internet icon I have the familiar 'r' logo next to the bars, and I cannot get mobile internet unless I tick 'allow roaming'. If I go to *#*#4636#*#* and go to phone information, sure enough it says I'm roaming there too.
The weird part is, not only do I not have this issue on the stock ROM, I don't have the issue with the Xiaomi ROM I had to pre-load before PE -- they both recognise my SIM fine and consider me not roaming. Furthermore, I get this issue with other custom ROMs loaded on-top (AOSP and ArrowOS -- using the same pre/base ROM). It's clear this is either an issue with the base ROM I'm using (although weird that I don't have an issue before I load the intended custom ROM on top), or some configuration issue once I load the intended custom ROM on top of the base ROM. To make things harder, I'm limited in what base ROM I can use as this process is pretty picky, and one wrong move and I get a boot-loop and have to start again.
Any idea on what this could be, or if anyone has experienced this before? Better yet, any solution would be great!
Thanks

Antenna radio signal shows an "X" where my signal strength is shown after system update

Hey guys, I've been nearly driving myself insane trying to find a fix for what seems to be a pretty serious, near-system breaking bug in the most recent Android 11 system update for the Blu View 3 (B140DL)
I had working antenna signal and strength working perfectly fine, after marrying my new SIM card's iccid to my carriers account. After marrying, I was told to reset my network settings, apply system updates (if any) and reboot the device. There was an update, so I proceeded with it, and when my phone was done rebooting, there was an empty antenna signal triangle with an x in it. I've heard about and seen ota updates have bugs in the firmware that cause issues but it's always been with top tier flagship type devices and there's a fix rolled out almost instantly. This being a budget unlocked device, I have had no luck with any kind of information about possible fixes or any being released; hell, I can't seem to find if anybody else has experienced this problem with the specific update on this build or not anywhere on the internet, and this update is from January of this year. I am going to post the build and specific software update that caused the radio firmware to not work, so hopefully that helps. I'm hoping that maybe there's a fix for this that doesn't involve reflashing the official firmware (can't seem to find the stock firmware for this device at all) and I'm humbly asking for any help or advice that anyone is willing to share with me. I'm having to resort to using text now & voice over WiFi with no access to my carriers services. Thank you in advance!
P.S. I also put a screenshot with the current kernel and baseband as well, because I'm not sure if either of those got updated during the last system update.

There is now firmware available. I'd try flashing stock

Dial *#*#info#*#* which will open up a menu to change radio from 3g to LTE only, and others, try them.
Also is your apn set?
