3g issue with MirrorLink - General Questions and Answers

Hi,
First of all thank you for having so much of info and help.
I am having a peculiar issue. I own a HTC 816 rooted device. Android 5.0.2. It has been working quite good until I recently connected it with the MirrorLink with my Car's smartlink connectivity. It was initially reluctant to connect and hung once or twice. However, it connected succussfully after few attempts. But, after that I am unable to connect to UMTS mode, when I manually configure the GSM/UMTS mode. Once the UMTS is chosen, not just 3g but the mobile network too gets disconnected (Cross checked the 3g connectivity with other mobile and also the same sim works in other mobile). The mobile supports 3 modes, Global, CDMA & GSM/UMTS. Out of these only GSM is working now. Earlier Global mode too worked (not sure about CDMA mode). At the same time, when I connect the device with the car, UMTS starts working. Once disconnected, the behaviour is unpredictable. Sometimes it works with UMTS for couple of hours and in some other times need to switch to GSM to get the mobile network.
I tried to do factory reset, relock, etc, except flashing the ROM (which didnt start at all when tried). Tried restoring the stock recovery as well to install the latest updates from HTC. But, its not installing. Any idea to resolve the issue, apart from flashing the ROM? Does android support stand alone driver installation or any other solution?
Note: Hope you wont suggest to throw the mobile and get a new one

[Q] 3G/Wifi don't work together

Hi guys,
My wifi/3G problem started with the 8107 update (Omnia7, not KK2), and i read about others have the same issue too.
The wifi connects to my home/work wlan, and strangely sometimes (but that's rare) working, and get pages to load on, but after a while it still shows the connection, but can't load any page in IE.
After i have done a hard reset, and reverted back to 7740, i don't got any problem to connect to my home wifi. I decided to update one more time to 8107. (If something will go wrong then I have a backup of my Omnia7 with WP7 Easy Backup).
@8107 the wifi keeps giving errors if 3G data connection and wifi is also turned on!
If i switch off and back the data connection switch (!!), then the wlan works again for a while. If i switch data totally off then works flawlessly.
I think the problem is only appearing if the 3G and Wifi is also switched on (maybe the OS doesn't handle properly the network settings in this situation)
Any workaround for that?
Maybe a homebrew, that can switch off data connection temporarily, if the phone is connected to a wifi network, and after disconnecting it will switching back. But I think if it can be done, than just on fully-unlocked roms (i have Omnia7, and unfortunately DFT SammyRainbow is not ready yet)
Or are there any registry entry that I can use to set this?
So any suggestions what to do?
I second that. Exactly the same behavior on HTC 7 Mozart since 8107 :-(
Happening to me too, Optus branded Omnia 7, 8107. WiFi works fine as soon as I turn data off, but its getting really annoying!
Have you guys interop unlocked? Im wondering if its related to that.

[Q] Phone antenna/Sim connection problem to network.

My Motorola Milestone XT720 phone all of sudden crashed while charging last week. I eventually got it to recover and boot, but then it went extremely hot and shut down. After removing the sim and SD card, then rebooting it, the phone turned back on. I reinserted the sim, but it won’t connect to my mobile network or to a wi-fi network. I got Sim replaced from Wind mobile and it still wouldn’t work, but my sim works in a old phone.
The phone seem to search for the network and finds Wind and Wind Away, but it won’t connect to Wind Network and goes to emergency call mode only. At one point, it did find the Wind Away network and connected to data, but not the home network. I did a factory reset with no luck, then a manual reset and still wont connect to the network. Finally today I downloaded RSDLite and flashed an SBF, but it still won’t connect to a network.
I almost think the internal antenna doesn’t send out a signal, but am not sure what else I can do to test the phone.
Any ideas or suggestion on why it won’t connect to wind home?
Hey there,
Looks like the baseband (modem) in your phone is fried. Could you dial *#06# and check if it appears 15-digit number ? Your best bet would be to flash stock rom with rsd lite and then wipe through stock recovery.
Hope it helps.

D6683 - Upgrade to D6633 Marshmallow Firmware - LTE Connection

Hi guys.
Just trying to share my observation and explore if we can do anything.
I am using D6683 (I think it is support to be a HK based handset). Using Lollipop, it has been working perfectly but 16GB not enough hence MM function that allow SD card and Internal memory merge is appreciated.
Since Sony decide to ditch us using D6683, the only option is using D6633.
1. Try using MM .575, it has huge connection problem. The phone will just stay in GPRS mode even connected to a LTE network. Driving from one point to another point, will just cause it to data connection to hang. Putting it in airplane mode and anything else won't work. Only reboot works
2. Restore stock and upgrade to .291, first day testing seem to be ok. Got LTE connection. It did try to swing a bit but it has been maintaining well. This i started driving with Waze. Connection start to go haywire, but it will be still try to reconnect. Data are "maintained" to certain extend. Let the phone along for about 2 days, the next thing I realize, only GPRS left. The signal logo got no more H, H+ or LTE. Check the phone service menu and all info confirm the LTE is available. Again a reboot fix the problem.
3. Change the setting to only WCDMA + GPRS. The phone was "perfect". No data hang issue and etc
Need all the sifu help. Assuming if the phone is rooted, how is the phone determine the connection method? I presume that the phone will initialize the modem to dial the connection. Can anyone share anything that we can probably trigger a redial and probably eventually inject into the phone data connection sequence. Again using Lollipop, there is no issue.
Appreciate any comments/advice.
Regards
Dan

Data Connection Drops on Moto G XT1045 (T-Mobile US)

I was curious if anyone else experienced or has familiarity with this issue. I've been dealing with this since I got the phone almost a year ago. Sometimes when my phone has been idling and I return to check something, the data connection will be unusable. The 3G icon will be visible but internet unavailable (4G works fine, but I prefer to have my phone set to 3G only). It's possible to wait 30-60 seconds for the connection to reset itself, or under settings, switching "Cellular data" or Airplane mode also restores it. Aside from that, the connection is mostly reliable & I don't have any usability issues once data has restored.
I've always ran CM & LOS on this phone so I haven't tried using a stock ROM (solution suggested in an older thread... Mobile data cutting out). I've also flashed the latest Lollipop Radio Firmware (fsg & modem). Thanks for any help.
Edit: I think this may have had something to do with visual voicemail being enabled. I've since switched to AT&T where VVM hasn't worked at all (they suggest using their app) and the problem has gone away.

Flashed US T-Mobile Galaxy s7 SM-G930T to Verizon. Wifi keeps disconnecting.

I recently acquired a Permanently Unlocked US T-Mobile Galaxy s7 SM-G930T. Since I have Verizon, I flashed it to the latest Verizon Firmware SM-G930V from sammobile using the latest Odin. Everything went perfect.
The only problem is that the wifi will not stay connected.
It will connect for a few minutes at a time, and then, despite it saying it is still connected to wifi, videos will suddenly not load, apps will not open. I run a speed test and then it will show the little exclamation mark on my wifi signal, only then showing that wifi is not connect or having problems. It's very tedious as I go based off the wifi signal to and since it says it's connected i am missing important notifications despite my mobile data being connected. I have unlimited data with my carrier so i could simply stay connected to mobile data at all times, but i would like to have my wifi working again. Does anybody know what may be causing this problem.
I tried flashing it back to T-Mobile. and once again everything works perfect. except for the wifi. So i believe it may have to do with the firmware, or maybe i need another file or files that i still need to install? I have been researching it for a week and i just can not figure out a solution.
I tried resetting my router, nothing.
Different older firmwares for Verizon from Sammobile, nothing.
Resetting Cache in recovery mode, nothing.
Unchecking Smart switch (function for it to switch between mobile and wifi automatically), nothing.
Unchecked Wifi and bluetooth scanning, nothing.
Can somebody please help?
Just asking, what were the bootloader versions of the T-Mobile and Verizon ROM's you went back and forth with? *Bootloader version can be found in baseband number i.e SM-930TUVS4CRL1, The 4 is the BL.
