[Q] {PRO} Roaming, no 3G/H data after flashing any ROM

I have a MK16a and have happily unlocked the bootloader and flashed a new kernel over the stock ROM; I have the latest baseband installed.
Any time I try to flash another ROM, I can't get mobile data to work. I show as Roaming, and can connect to GSM but nothing else. APN settings are good. Flashing a different kernel doesn't seem to help either. I tried re-flashing the stock ROM and then a kernel and then the ROM I wanted, didn't work. I tried doing a Factory Reset over the stock ROM that works and flashing another ROM, didn't work. If I restore the backup I made before doing any of this, everything works again - I just can't get any other ROMs to work!
I've searched XDA and other sites pretty extensively and I'm not coming up with anything. Anyone got any ideas?

If you can, ask operator to change your SIM. Should be a few minutes process at the store. I had same issue a year ago as well, although I left the country already, so it was not a problem.
Just a note, that all questions should be posted in Q&A section.

Interesting idea. I know the SIM works ok with the carrier-provided ROM on the phone, but it is a fairly old SIM card. Night be worth trying, tahnks for the suggestion!

*facepalm* Yes, of course they should.

Any luck yet?
If still same situation, make sure you are using baseband from MK16a firmware, not MK16i.

If your carrier is so-called virtual network operator, you may need to enable national data roaming in the settings. It's available in the mobile network settings at least in CyanogenMod ROMs.

Finally got around to doing this! Updating the SIM (which we figured out was probably between 5 to 8 years old) has resolved the issue.

[Q] Flashing International Roms

As the title states....
When I had a Galaxy S4 we were able to cross flash ROMs (e.g. use an AT&T ROM on a T-Mobile device). The ONLY stipulation was that you needed to flash a T-Mobile KERNEL after the ROM flashed or the phone wouldn't work. Would this be the same concept for us with the G3? I don't see any kernels at the moment so I'm assuming it's a "no-no" to flash one of the other ROMs but once we start getting custom kernels I'm assuming we're good to go.
Would this be correct?

Not sure with the G3 but make sure the first thing you do is back up your efs. I messed up my G2 flashing a International Rom.

I think we are specifically talking about the LG3 since its by a complete different manufacture and a complete different phones.
Note 3 can also flash international but it get wifi issues, nfc issues, and the fact that it wipes your whole phone.
I'm new to the LG scene as well...so ya, as one mention above they messed up their phone doing so with the LG g2

it is the same as any other phone. the wifi and connectivity issues come down to be a radio/baseband related. you need to flash the correct baseband from tmo to have everything working

yea just flash the correct baseband and call it a day

If you want to flash international ROM just for language you want, you may look at which language T-Mobile version has first.

My understanding though is ROMs don't flash baseband therefore that shouldn't be an issue. So kernel issues... Do we just not know yet?

I assume you mean the D850 since D955 is the original G flex and you should never ever ever even think about flashing a ROM from that phone to this one as they are completely and absolutely different. Also, call forwarding is buggy across all Lollipop ROMs as of now so an AT&T ROM won't fix that. Also, its never really a good idea to flash a ROM for a different variant that's not intended for your device without checking out what partitions its gonna touch first.

[Q] Unlocked Sprint update

Hello everyone!
I would greatly appreciate if someone could show the right way to get my phone fully functional;
SPRINT HTC ONE M8
GSM SIM UNLOCKED for use on GSM networks
S-OFF
Rooted
TWRP
HBOOT 3.18.0.0000
RADIO 1.08.20.0612_4
CID-11111111
software version: 2.16.654.4
android: 4.4.3.
Issue:
1. I can not install any OTA updates, and the notification keeps popping out.
2. Mobile data is just not working properly even though I did everything as said here;
http://forum.xda-developers.com/sprint-htc-one-m8/general/enabling-3g-umts-countries-t2847461
As I did my research, it was some kind of a major bug on this series of Sprint M8 phones with breakdowns in mobile data. However, since I can not get any updates, the problem perists.
I tried installing custom ROM's, but so far ARHD 22 didn't even boot and LiquidSmooth couldn't detect the SIM card at all.
I know there are quite a few tutorials and "how-to" threads explaining all you need to know about RUU, cusotm ROM's, etc. However if someone could tell me what exactly to do and in which order (return to stock, then update?) I would greatly appreciate it.
Many many thanks!

Easiest way to get it back to stock is just flash the Sprint H/K RUU. You can download it from HERE. Just run it and connect your phone when prompted and follow the instructions (I'd probably change your CID back to the Sprint one first to be on the safe side but as you're S-OFF it shouldn't be needed). You might also need HTC Sync Manager installed. If so, you can get it HERE
This process will wipe the phone completely so back up any data first but other than that you'll at least be back to stock and then troubleshoot any issues from there

Thanks
Many thanks to everyone.
Any chances of loosing the SIM UNLOCK when going back to stock completely?

Nope, that shouldn't be touched but as I've not had a SIM-locked device in years I can't say for certain

Why not 34? Lol Sprint is up to date on its software you could just update to the lollipop firmware, and I could pull some of the files I've got to see if I can help you get it running, I'm on Leedroid right now so the process should be the same for ARHD.

Sorry if some of my questions are a bit dum, I just got from a long trip and have been out of this all rooting busines for a while...

You can or you can go to the Sprint android development and flash the updated recovery since you are s-off and it'll permit you to flash lollipop roms without many issues but there is still the files that need to be modified for ARHD to work correctly like the boot.img and a few others.

Power+vol up for about 15 seconds then power+vol down to get into recovery. You cant flash it unless you swap out Sprint specific files otherwise you'll get what just happened or boot directly into boot loader.
Like I mentioned I can pull the files together and see if I can get it working for Sprint tonight when I get home but until then flash either fluent Rom or stock if you want lollipop or just flash bad boyz if you don't mind kitkat

For me, the biggest issue is the mobile data breakdowns... I know I read somewhere a while ago it was an issue with some Sprint M8 models. I would like to get everything working w/o problems since it is GSM unlocked, and via QPST I unlocked all the bands.

[MODEM]/[RADIO] [20B] TMO D851 LG G3 Lollipop Only

I was having a problem trying to find the modem for my D851 here on XDA. There were many plainly listed for D855 and other models of the G3. I am using Paranoid/ASOP 5.1.1 Rom and I accidentally flashed a D855 radio. Rookie mistake, I know... And thought I backed up the modem along with the system files. Well I didn't and lost my imei, apn, signal and all... So while searching and again not obviously placed easy to find I read a thread and found one, flashed it, and it returned everything to normal without having to flash back to stock rom and blah blah blah... From what was listed, this for L 5.0 and up.
1. Boot phone into recovery, preferably TWRP
2. Flash the modem zip DOWNLOAD: https://www.dropbox.com/s/xz26z91hej9ryz3/LGD851.20B.MODEM-iNb4TMO.zip?dl=0
3. Reboot
I didn't make the radio, nor take any credit for its creation. I'm just trying to make it easier for T-Mobile D851 users on Lollipop to find incase they have deleted or lost theirs like I did...
I am not responsible for any issues or problems that may be encountered by using this.
I hope this help those in need like it helped me... Please let me know...

Im currently having a major issue with the lollipop update. I had my d851 with t mobile and I wouldn't lose lte when I would make a phone call... I currently switched to metropcs and now when I make a phone call I lose lte and my signal drops to 4g. I tried everything... APN, restoring the phone, called metro like a thousand times and nothing. Any help would be greatly appreciated.

Flashing the 30D modem seemed to help quite a bit, the signal will drop to 4g while you're on a phone call but the data is alot faster. Give it a try, it worked for me.

Well, I went camping over the weekend and of course the phone dropped service again. The cell signal was weak and the data was almost non-existent. Luckily I brought an old phone, re-activated it, and was good with LTE signal. My question is would flashing a different modem help? I have the LG-D851 with SW version D85130e so I assume that has the 30e modem. Is that correct and would the 30d modem be better? Thanks.

No idea. Could be something else (mechanical) causing the issue. 30e is the latest for our phones. You can also drop it down to 30d & see if it is any better.

That's what I was hoping to do but was trying to see if there was a way to just install the 30D modem instead of loading the entire phone with the older SW version and having to re-install all of my apps. I downloaded the modem file but after doing some research I couldn't figure out the procedure to install it. I saw a few videos about a TWRP recovery but I prefer not to root my phone. If I have to root it in order to get it working then I will...I just wish I could figure out what the issue is. I saw a few other people mention issues with the LTE setting defaulting back to WCDMA/GSM (which I experience) and they said the 30E modem could be the issue. The phone was just wiped clean a few months ago before I bought it from the previous owner.

yeah without having root, your options are limited. If you own the phone, I would say go for it, if you are leasing it, then take it back to where you got it & tell them it's reception sucks.

I own it and bought it second hand. According to the previous owner he didn't have any issues with it but who knows. I assume if I root it and load the 30D SW I will have to load everything from scratch? Is there an LG backup program for this phone? Thanks for the help.

From any home screen, tap Apps.
Tap Settings.
Scroll down to 'DEVICE,' then tap Backup & reset.
Tap LG Backup service > Backup & restore.
Tap Restore from backup.
Locate and tap the SD card backup.

I have the TMo version (D851) & the first thing I did was root it & install a custom ROM to get rid of all the Tmo crap that is stuck onto it. ugh! I don't use my phone all that much for calls, mostly emails data & music playing, so losing the stock Wifi Calling function wasn't an issue for me. Currently on the OctOS Nougat weekly builds, tremendous ROM, great battery life fast & smooth & decluttered. Since you already own the phone & do not have a warranty, you've nothing to lose here. Do some reading in the threads on how to do it, you'll be very happy once you see how much better your phone can be. You put on it only what you want to put on, less junk, less memory hogging.
