don't manually upgrade to 2.3.4

there seems to be at least 3 users who can't connect to a network after manually upgrading judging from this thread:

it may be best to wait for an ota upgrade. (and let's not fill with this thread with "it works for me" please.)

I'll update my ota thread
Sent from my Nexus S

I hope google can quickly send all the ota. There should be some people try every efforts by downgrade then upgrade or going thru any path to get the 2.3.4, may finally mess up the phone ...

it seems impossible to downgrade.
google, you broke my phone.

Do you have the correct build number?

Try flash an older ROM first, then flash a known working radio for your phone. Hope that gets your phone working again.

under the battery, it's a gt-i9020
the ssn is i9020gsmh

Manually flashed my Nexus S and now im having poor reception/disconnects on 3G data. Also my GPS didnt improve. Im not rooted and have stock android.
Did I do something wrong while upgrading to 2.3.4? Can i revert to 2.3.3?

I did the manual update for 2.3.3 and 2.3.4 nothing went wrong

i manually done mine and have no such problem.

let's stop with the "i did it, and i'm ok" posts, which if you read in op, you'll see i wrote the same.

i too unable to connect to network. APN still there but i can't connect to network. But i still able to downgrade to previous version. if unable to, try restore from the latest nandroid backup? i manage to restore to my CM7.0.2. im gonna wait for a bit longer~~~

did any of you try to use your SIM in a other phone? did it work?
did any of you requested support of your carrier ?
and did any one delete their APN's(yes all of them,total reset.factory ect ect)
and tryd to retype the apn settings manually??
DID any one of you guys notice you have to set the IPV4 and IPV6 options in APN Editor????
or did any one RESET your sim?(yes you can,there are codes for that.ask your carrier)
if i want to connect to my carrier's APN i have to fide a bit with the setting and leave things out.
like BEN.NL( T-mo) says APN type needs to be: internet.
if i type internet in the APN type.
my network(3G ect) wont work.
i i leave APN type empty.
all works fine.

- didnt try the SIM at any other phones
- didnt request support yet (carriers in Brazil suck, they dont even know the APN settings)
- tried deleting and adding APN now, not enough time to test it yet

unlocked and upgraded to 4.5.91 NO DATA :(

Hello guys,
I have a sim unlocked, bootloader unlocked, 4.5.91 gingerbread, AT&T atrix 4g on Fido network in Canada.
I made the apns using the same apns from when i was using .81 but I can not seem to connect via 3g/2g/gprs. The only way to use the internet is via WIFI.
What do you think is the problem?

try a reboot...

I'v rebooted at least 10 times now

did you make a backup?
You can go into your Mobile Settings and do a 'reset to defaults'.. otherwise, if you made a backup of you system file, you can copy 'apns-config.xml' from /System/etc to the same directory on you phone...
I had the same issue, I just did the 'reset to defaults' and got my apns back.. but going to copy my previous apns-config.xml file cus that had custom apns..
hope that helps..

I alread have tried reseting to default and adding the APN's again.
as far as system back ups, I dont have one

You can find the apn settings online, i would create a new apn and put those settings you find in. I had issues with mine, and when I did that, it fixed my problems. I put a link below that has the apn settings.
androidforums.com/htc-inspire-4g/276917-inspire-4g-apn-settings.html
Edit: sorry, I didn't realize you weren't using att...but same idea, just manually set up your apn network

Also, you could have the wrong mobile radio installed. I know that they are set to pick up certain frequencies and that radio might not work on fido.

Hmm.. that is weird, maybe you can pull the apns-config.xml from one of the Bell ROMS or from one of the P-ROMs floating around in Dev section to replace what you have now for APNs... just adb it to /System/etc/ , then reboot and go back into your APN settings to see if doing another reset to defaults will work if they don't show up after the reboot..

How do I check what radio version I have installed?
as far as icons are concerned, I get H+ icon

Go to about phone in settings and its under baseband version. I had a similar but not same problem, which was solved by resetting the apns as that seemed not to work in your case. I would try to flash a new radio.

I have the same problems after 2 day of 4.5.91 update I loss the complete data conection, any apn that I usualy use work, I dont have any idea to solver the problems, work only for wifi, I use a diferent radios and is not solver the problem. I have a atrix AT&T root + bl unlock + 4.5.91 + 30p radio.

Here's a CWM zip file of ton of APNs. Just install and go to your APN list and reset to default. If it's an APN issue.

Just a (possibly) stupid question, but after you reset to default and input your apn settings, are you clicking on it so that it is highlighted in green?
If all of that doesn't work, I would try re-flashing whichever rom you are using through CWM recovery and see what happens.

[UK] My Galaxy S4 never shows 4G symbol in 4G area

I've heard the H+ symbol should turn to 4G symbol when in a 4G area.
I've never seen the 4G symbol appear when I'm definitely in 4G areas (including Birmingham and central London).
Is the information I've received wrong, or is there a setting wrong on my phone?
The phone is set to "WCDMA/GSM (auto connect) and is running the latest Samsung ROM (Android 4.4).
My service provider is Three.
EDIT: Solved! Root, then navigate to Data then Property. Rename Persist.radio.lteon (don't delete in case something goes wrong) and reboot.

The phone have to be set in LTE/WCDMA/GSM for receive 4G. The firmware installed should be the problem. Anyway dial *#1234# and attach the screenshot pls :highfive:

Trying to root a Moto g4 from Amazon

Hello, everyone. Thanks in advance for any help provided.
Recently, I purchased this phone from Amazon, and I like it a great deal, except for one thing -- the wireless hotspot does not turn on. When I try to activate it, I get the following message, after it checks subscription status:
"Account not set up for tethering
To enable, go to att.com/mywireless or dial 611"
Here is the issue though -- I have the service through Tracfone's BYOP program, and they do not support the feature, even though they do not mind you using it if it happens to work. So, they will not enable it. Further, AT&T cannot help, as the service is through Tracfone and they do not have access to their customer's account information.
I have looked around this excellent forum, and I have found that this issue can be fixed by using ADB shell to enter this command:
settings put global tether_dun_required 0
as well as adding this line to the build.prop file in the /system folder:
net.tethering.noprovisioning=true
I was excited by this, and attempted to do it through ES File Explorer using root explorer -- and then told the option doesn't work on this device. The reason, of course, was because the phone is not rooted, so I figure, if I can root my phone, then I can edit the file, reboot the phone, and enable the hotspot. So, I continued researching.
I learned in the last day or two I learned that you cannot unlock the bootloader on this phone, something to do with Amazon's agreement with Motorola as a way to keep people from removing the advertisements. So, I cannot go that route.
I downloaded KingRoot (version 4.9.6) and attempted to root with it... and it failed, multiple times.
So, I was hoping someone might have a suggestion of what step or steps to take next. Any help would be greatly appreciated.

Hotspot works
On my 32gig Amazon G4 the hotspot works without rooting and no additional software. I've got FoxFi loaded, but it has never been used on this phone, and was not running.

I would avoid Kingroot as that won't get you rooted. Tethering is iffy at best depending on your carrier. Some will suspend your service if they catch you tethering which they can easily do. Tracfone used to be pretty quick about suspending service for anyone tethering so good luck on getting it to work.

You can use adb mode if you turn on USB debugging in developer settings. Settings > about phone > tap build number a lot of times to enable it.
Then it'll be in settings. And you can use system-wide adb for Windows to make it easier to use ADB.
Or, you can try an app called EasyTether to tether.

I know the ADB commands to try; I listed one of them in the OP. However, it didn't help in my situation.
EasyTether doesn't have a wireless network tether option, and I have tried other apps too -- such as Pda+ -- that will not enable the wireless tether.
What I need is a way to edit the build.prop file, but it appears that I cannot do it without rooting.
Someone mentioned there might be an issue with Tracfone not permitting it. I conferred with Tracfone, and, though they do not support the feature, they do not mind if you can get it to work.

Xfinity Mobile Data Not Working

Hi,
Is anyone else having a problem with Xfinity Mobile data? I can make phone calls, but I can't get any data connection. This was a phone I bought from Sprint, and due to their messed up unlock system, it got relocked, so I manually unlocked it by using this method: https://forum.xda-developers.com/showpost.php?p=75994498&postcount=360
After that, the phone got unlocked successfully. It accepted a TMO sim, and I was able to update to newer firmware. Today, I decided to put it on my Xfinity Mobile line, and I just can't make data work. Any help would be appreciated.
Thank you,

OK. I think I narrowed down the problem. APN setting has VZWINTERNET. It's supposed to be COMCAST.RSLR.VZWENTP based on what I read on the internet. The problem is, I can't edit or add a new APN. I saw someone else talking about this APN setting problem, and his was resolved with the April security patch https://forums.androidcentral.com/e...cant-add-edit-apn-all-sudden-lost-4g-lte.html
I have that security patch already installed, but my problem persists. I can't change APN. Any help would be appreciated.

It's possible Xfinity locks the APN settings or that it has something to do with yours being the Sprint version. I would power the phone down and remove the SIM. Power the phone on with no SIM card and when you are booted up go into settings and reset the network settings. Power down again and insert your Xfinity SIM. That should ensure that the new SIM populates all the network settings.

Thank you for replying. That did not work. I don't think it's Xfinity. The problem is that APN gets locked to VZW instead of Xfinity's APN, which is why data doesn't work. I can put a TMO sim card in it and it works fine, so I don't know that there is something wrong with the phone itself. If you have any other suggestions, I would appreciate it. I'm desperate to get this working.

In a Reddit thread, a user says you need to disable Enhanced LTE:
Under Settings > More > Cellular Networks, disable "Enhanced 4G LTE Mode" and set "System select" to "Automatic"
Haven't tried it myself, but I'm thinking of switching to XM and would like to know how this works out for you.

Get your original Xfinity phone factory reset the original Xfinity phone put your Sim in go through activation. This should work for you this also fixes volte on Xfinity If your volte ever gets deactivated. Anyway from what has happened to my other phones sometimes the apn can get changed on the Sim and got carried over somehow. Resetting the original Xfinity phone will bring the Sim settings back to the Sim card thus fixing your apn settings.
(Another way is to use another phone to edit the apn settings)
I also have Xfinity mobile and it's working fine. Just sometimes my apn gets uncheck and I don't know why
If you messed with bands.
Also make sure you go and download hidden settings from the playstore if you messed with your bands and selected American bands you need to select automatic bands if you messed with radio information page settings.
I messed with bands and it caused phone calls to not work.
---------- Post added at 10:08 AM ---------- Previous post was at 09:31 AM ----------
The Sim saves apn settings and I did notice the first time using this essential phone I had 2 options in the apn and I read carefully which one to select. It may have saved the incorrect information to the Sim. I did this once on a Moto phone and I thought if I put Verizon apns instead of Comcasts I could get better speeds. But I caused my data to stop working. I reset the Moto phone and u still had the problems. I looked for the apn for Comcast couldn't find it. Then I thought of either editing the apn using another phone or using the original Xfinity phone. But it does get saved for sure. I ran into this issue before and I'm pretty sure this will resolve the problems.

Yes. I manually sideloaded Beta Oreo build, even though my phone already had the official OTA Oreo on it. That fixed the connection issue altogether.

Yea, it was just a desperate move lol. Glad it'll be helpful for others.

I had the worst time making the XFinity mobile work on Android Pie with the October patches in place and finally got it working. Basically, there was no way to edit the APN configuration even with root on the device via actual Android. What I did to fix this was the following...
-Followed the rooting procedure to get TWRP and Fastboot installed
-I then used "Termux" to copy the APN points configuration file to a writable location. In my case I copied the file from "\system\etc\apns-conf.xml" to a "\sdcard\Download". Keep a copy of the original file.
-I then simply copied the file over to my computer and opened it in NotePad++. I did a search for the following string in single quotes: 'carrier="Verizon"\n mcc="311" '
-This should pull up 5 results in the search and you should confirm that each of the lines has the mnc value set to 480, 'mnc="480"'. On each of the sections that came up, I switched the following variables as shown below...
apn="COMCAST.RSLR.VZWENTP"
authtype="0"
protocol="IP"

-Once you have edited the file, copy it to a writable location on the device, like "/sdcard/Download".
-This then requires rebooting into recovery mode with TWRP and you will need to make sure you have encryption and a PIN disabled on your device to make sure you have full access to the device file system.
-Within the main TWRP page, select "Mount" and you will need to have the "System" and "Data" partitions selected.
-Return to the main page and select "Advanced" and then "File Manager".
-Next, locate the original apns-conf.xml that you copied earlier. It should show up as being in "/system/system/apns-conf.xml". Click on that file, and select "chmod 755".
-Next, navigate to where you have the edited apn file located. Copy that file over to replace the apns configuration file at "/system/system/apns-conf.xml". Just make sure you have a backup of that original file before replacing it.
-Finally, reboot your phone into the OS and you should magically have Xfinity mobile working.
This took a lot longer than I wanted to spend getting it working, but I believe this is because of the carrier ID and MCC being shared with Verizon instead of a separate one for XFinity mobile which forces it to default to the first Verizon APN setting which doesn't allow this to work. There are other ways to edit the APN configuration file, however I found it was quickest to do the actual file replacement with TWRP since that gives you full file system root access.

I had the worst time making the XFinity mobile work on Android Pie with the October patches in place and finally got it working. Basically, there was no way to edit the APN configuration even with root on the device via actual Android. What I did to fix this was the following...
-Followed the rooting procedure to get TWRP and Fastboot installed
-I then used "Termux" to copy the APN points configuration file to a writable location. In my case I copied the file from "\system\etc\apns-conf.xml" to a "\sdcard\Download". Keep a copy of the original file.
-I then simply copied the file over to my computer and opened it in NotePad++. I did a search for the following string in single quotes: 'carrier="Verizon"\n mcc="311" '
-This should pull up 5 results in the search and you should confirm that each of the lines has the mnc value set to 480, 'mnc="480"'. On each of the sections that came up, I switched the following variables as shown below...
apn="COMCAST.RSLR.VZWENTP"
authtype="0"
protocol="IP"
roaming_protocol="IP"

You couldn't cut and paste the file back with a root file manager? Maybe a magisk module? And does this lock you to Verizon?

I'm sure there are other ways to get the file back there, but I found my approach to be a quick bypass for other methods of getting root.
Regarding Verizon, It would probably break a Verizon connection for a sim carrier code of 311480. However, since this post is about Xfinity mobile, this is the quick way I got it working. In the future I want to change the priority on the APN configurations which may allow Xfinity mobile and Verizon to play nicely. The issues that have caused this are Android Pie restricting people from changing settings on the phones they own and Xfinity mobile being either too lazy or cheap to commit to their own carrier code and provide that information to manufacturers.

Breaking a Verizon contract for sim carrier code would be a drastic move, considering.. The only money you have to spend is $5 on a Verizon prepaid phone card. Go into a Verizon corporate store and they will give you a sim, ( it's $20 if you don't go to the corporate store)
