[Q] HELP! 4g LOST

HELP! 4g LOST / not working
THE SHORT OF IT: I flashed a custom ROM & kernel. They didn't work properly, so I flashed my nandroid to get back to rooted stock. NOW I HAVE NO 4G or signal of any kind (wifi works)!!!!!!
THE LONG OF IT:I'm in South Korea using the Galaxy Note 2 on the carrier LG with their U+ LTE service. As far as I could see and have been told my phone ONLY uses 4g (no 3g or other options to check). I was advised to flash a Tmobile or ATT Rom (I chose the Tmobile AOKP) as our U+ phones don't have their own Roms & Forums and I flashed a custom kernel from sjkoon a developer posting kernels that work for our phone. Others have done the same thing and reported no problems. After flashing, the new Rom & kernel, the phone booted in the Google startup helper I could not gain access to any signal or wifi to access or create a gmail account.
So, I nandroided back to stock (rooted, mind you, using chainfire's exynos exploit) but my 4g won't work, only wifi does. So, I have NO way to make/receive calls. I've verified a number of pieces of information through various avenues and have the following:
PHONE INFO
My Access Point Names says "LG U+" with "internet.lguplus.co.kr" underneath. There is no option to change it or edit it, just a radio button with no other options (is this is fine?). I was advised in another forum (http://forum.xda-developers.com/showthread.php?p=36895160#post36895160) to change mmsc's value to http://omammsc.uplus.co.kr:9084, but I dont' know where that option is to change it, or if this is a problem.
I also used the the "Phone Info" app and got some of these readings:
In Telephony, have a Device ID, my Network type is 3, Sim State 5, it shows I have a SIM operator and country, Serial Number Subscriber ID, etc. The only things that MAY be strange (I don't know what their original values should be) are that Call State, Data Activity and Data State are all 0 and my Network Operator Name, Network Operator and Network Country ISO are just blank. Even if I wanted to change any of these I have no idea how...
PLEASE HELP & THANK YOU!
It's strange. I spent the night/morning searching forums for a solution but not sure exactly what to do. Please, help me or point the way to fix this issue if you know how and thank you very much. I'm willing to buy you a beer or buy your newest app, say thanks on all your posts for the next month, whatever! Hehe. ...:crying:

[Q] Problem with phone already activated on VERIZON INC2

Dear All
first of all, sorry for my bad language.
my problem started when i purchased an used Inc2 from swappa, i am expert in flashing ROMs for HTC phones.
when i got the phone, i s-off, installed recovery and installed custom ROM supports GSM, as i am living outside USA, and everything was good (GSM and data)
one day, suddenly the phone was not able to get a H data, only E, so i decided to factory reset to solve the problem, i return to stock ROM using RUU, then when i turn it on for the first time i discovered that its still connected to verizon Network and gave me a roaming signal, i know nothing about verizon network or how to disconnect my phone from their service.
don't tell me to contact the original owner, because i purchased this phone more than one year ago and i totally forgot from whom i toke it.
THE MAIN PROBLEM NOW, every time i insert my local SIM, the phone switch from roaming mode (CMDA) to global mode (GSM), which is OK, but when i receive or make a call, it restarts automatically !!!!
i had tried all the ROM, RUU, radios in the development section, with no hope, so, i think the problem is occur from the conflict between CMDA signal an GSM signal!!!???!! or something else, so i guess the first thing i have to do is disconnect the verizon service, BUT HOW?? somebody please help me

any thoughts folks?

Can you post your phone's settings, mainly the ones under "About Phone" including kernel, mobile network type, service state & software information, etc.?
With a local Sim card, it is possible that you device would boot up & switch to Global Mode (by default) with preference for CDMA, but you should be able to manually change it & semi-lock it to GSM only? What happens when you tried that?
There is a # of GSM only Rom that you can flash, assuming you've rooted it again & maintained S-Off with a custom recovery re-installed - and, that it was properly Sim unlocked.

Im on GSM with chilly's beanstalk 1.30 (4.2.2) and I have no problems, check if a wipe with antivenomSDW, helps.

[Q] At&T Note 4 on T-Mobile - help / questions

Hey XDA World,
I just bought (3) AT & T Note 4 devices off ebay, stating to be factory unlocked & for use on GSM networks (such as T-Mobile USA)... I have (2) questions.
# 1 - How do I get rid of the AT & T Boot sequence / firmware on the device.. I really want either T-Mobile, or International screen
#2 - How do I get Lollipop updates without locking the phone ? Can I get them via OTA on T-Mobile network ??
Sorry for the newbie questions, but want to make sure I do the right things to avoid an expensive mistake. Thanks in advance for the reply
Thanks,
Rick

Question 1. These phones are unrootable at the moment so know messing with system files and it's possible that they will never be rootable.
Question 2. I doubt you will get lollipop update ever unless you put AT&T Sim in the phone. Updates are carrier specific and AT&T OTA will never complete without there Sim. It will error out every single time.
Good luck

[Q] Which ROM for an Unlocked HTC M8 branded Verizon, running on MetroPCS carrier??

Haven't received a reply, so I'm updating my question with some new information.
I used Sunshine & am now rooted & s-off.
However, I still don't know what ROM I'm supposed to use:
- My HTC One M8 is a branded Verizon phone, but I've been running it successfully on MetroPCS
SO:
- Do I use a T-Mobile ROM (MetroPCS was purchased by TM and I believe my LTE & 4G comes from TM network)?
- Do I use a Verizon ROM?
Thank you in advance,
Hello,
I purchased an unlocked HTC M8 branded Verizon and have successfully been using it on MetroPCS' LTE network.
I'm considering a different ROM in order to:
- Remove all the Verizon bloatware
- Get as close to Android as possible (I'm dependent upon all the Google apps, gmail, hangouts, calendar, etc.)
- Hopefully get a working FM Radio
From all the threads/replies, I still have not been able to figure out which ROM I'm supposed to use:
- Since my phone is Verizon branded HTC M8, do I have to use ROMs developed for Verizon?
- Which ROM would get me closest to my goals?
Thank you,

Answers to my question
Okay, here's what I had to do to get my Verizon M8 which (thanks to Sunshine!) is s-off and unlocked and rooted to run lollipop (5.01).
1. So the good folk at therootninja.com were able to answer my question and they told me that I have to use Verizon ROMs.
2. I used these instructions to upgrade my phone to 5.01: http://forum.xda-developers.com/showthread.php?t=2727831
3. There are 2 issues I've encountered:
A. My mobile data says "disconnected" and no matter what I've tried, can't get it work.
B. Smart screen security (so my face can unlock my phone) does not work
Does anyone know how to fix "mobile disconnected"? Here's what I've tried so far and doesn't work:
- Used different combinations of APN that I found posted in this forum & via Google searches
- Recovered to my previous version (4.4.4), copied down the APN settings, re-recovered 5.01 and used the settings;
- Factory reset & put in the APN settings
At this point, I'm back to running 4.4.4 because I need my mobile data to work and my next step might be to go back to 5.01 and take the phone to MetroPCS and see if they can get it to work.
I honestly don't know what to do & would appreciate some help from this community.
Thanks in advance,

Some more answers
Okay, so today I restored to my last 5.01 image (twrp backup) and walked into the MetroPCS store.
Here is the APN info the gal, Tiffany, input which worked(!!):
Name: metro pcs
APN: fast.metropcs.com
MMSC: http://metropcs.mmsmvno.com/mms/wapenc
That's it, nothing else. I left the store estatic, drove home and when I clicked the menu, Mobile Data>GSM/UMTS Options, I reviewed the settings, BUT... when I exited the menu an automatic save was done and I lost my mobile data.
After much futzing, to include deleting the APN info & adding a new entry with the same info, I've found that by selecting LTE/legacy 3GPP mode in preferred network, I'm able to get mobile data working again. Go figure! :-?
In any case, the only final two things which are not "perfect" are:
1. Unrecognized SIM error (@DOTT suggested an xml file to edit)
2. Smart lock does not work, facial recognition never appears.
Hopefully someone will read this post & provide a reply. To date, I've submitted many questions and have not received many replies (2).

Getting a Verizon rom to work on another carrier is pretty easy. Since you are s-off you could use qpst to unlock the bands needed to get 3G and 4G working for MetroPCS. If you cannot get data to work, try a Verizon rom from the Verizon section. Verizon phones and Sprint phones have odd mount points,so flashing a rom for a different phone is not recommended. I know from experience on my m7 that a Verizon cannot be Co vetted to another variant. I don't know if the m8 is the same story as I have an AT&T branded converted to T-Mobile for the m8.

Long story short: try the Verizon m8 section instead of this one for help please. The people in this section have the T-Mobile branded m8 and yours is different.

The phones that you purchased are all "gray market" meaning that they have been unlocked using methods not supported by the original manufacturer. They were never intended for sale outside the U.S. (Whether this is illegal or bot is not a question that I will try to answer.) If you try to update them, you will lose the unlock (they will revert to Sprint) and you will need to unlock again yourselves.
This is happening with many phones, not just the S6. You can read about it here: http://www.androidauthority.com/beware-the-grey-market-retailers-648562/
