I have an LS990 that I had paid to have unlocked using the cloudy rom. I had it unlocked to be able to use T-mobile. I am having alot of difficulty with signal as I'm at between -90dBm and 3 asu. I've switched between all the bands and options that it gives me under the network options and nothing seems to help. I have debating on reflashing to a different Rom to maybe get better results. One thats maybe more optimized for T-mobile and just more updated in general.
I have jailbroke Iphones before but never an android so I am not sure what to do exactly even though I believe it would ultimately be the same concept.
I know this is my first post on these forums so alot of members might night be willing to help but any help would be better then know help
So I guess this is what I ask
1. Can you give me the steps to flash the rom
2. If I would need to unlock the phone again to be able to use T-mobile the steps needed to do so
3. How to update the PRLs with T-mobile so I can achieve a better signal(if needed or able to using my current ROM
To confirm my current Rom is the CloudyG3_1.2

I've read that the att version of this has a locked bootloader. I've also skimmed and read there are different versions of the bootloader for this phone as well.
My question is that I'm going to try to buy one off ebay but I want to make certain that I can root and install custom roms and kernels. I don't care about warranty info so thats no problem. However can you root on any bootloader or only the old one? If there is any info on this I'd to read about it. I just don't want to buy an updated phone and not be able to do anything with it like I did my optimus g pro which is not properly unlocked. Because if the bootloader effects this then I'll have to ask selllers what version it has and they likely won't know. I also read there are different modems and such with this. I just want to make sure i have total control over this phone unlike some that haven't been hacked thoroughly.:angel:
So if anyone wants to call me a noob and direct me towards a thread here I would gladly appreciate it.
The T-Mobile version DOES NOT have a locked bootloader, only Knox. Make sure you get an SM-N900T if you don't like locked bootloaders. The AT&T version is labeled SM-N900A, verizion is SM-N900V, and sprint is SM-N900P. All except the SM-N900T (and the Canadian SM-N900W8) have locked bootloaders.
Rather than start a new thread, I got a note3 in the mail. I know its an n900t but i don't know anything else about it yet.
my question is, I've seen a few things that say hlte and hltetmo. I'm researching how to do this stuff so I kinda know about it when the phone gets here. My question is, Ive seen this on the cyanogenmod website and twrp website.
Whats the difference? if any? I assume the tmo versions are for our phones, but if the regular hlte work then why the "split" in versions?
also what is generally the "best" most compatible recovery? I've seen cwm, philz cwm and twrp. I was just wondering if someone could just tell me which is the most stable
I just got the phone so i'll be looking into whats the best but if anyone has any suggestions for my previous post I'ld greatly appreciate it
I suggest avoid 'hlte' and always choose 'hltetmo'. 'hlte' might be the international version and with some things, like custom Recovery, it will cause boot-loops on the SM-N900T. When you see something contradicting what I just wrote assume it to be true for only that thing.

Ok, so I have the us cellular version sm-n910r4 and I'm having the hardest time finding any roms or even forums for it. I know about team us cellular but there's just not much going on over there. I am rooted, running twrp 2.8.6.0 (I think), and have supersu 2.49. I know there are some roms out there and I've even tried cm12.1 but there has to be more options! I've read a few places that certain other model numbers work with the us cellular model but I'm not sure if that's true. Does anyone know? Any help is greatly appreciated. Sorry for asking about us cellular here, but I don't know where else to go and xda has the most active and helpful forums.
yep no info anywhere
I can't find anything anywhere I can't even get it rooted I'm on a note 4 also same us cellular you mus be on 4.4.4. Even less info for 5.0
I'm actually on 5.0.1
How to root the phone runs on 5.0.1
I got the same phone this couple dates. But the phone is updated to 5.0.1 and I got no way to root it. Is any help for that? Thanks.
Some help not much. I did have root on it and nearly sure it was 5.01 . Am fairly positive that I used odin and a tar file I found published. I found the tar file but now and bricked and cannot get it to work any more. I can get the file to load or so 0din says success but cannot get past the usc screen on boot now.
BTW USC agreed to set me carrier free and I SHOWED AT THE store agreeing to do so in NC only to find I was bricked.
Ever since I got my m9's I have been a flashing fool! I absolutely love it. But I recently learned a trick to improve my reception so I decided I would share.
I live in a city and my reception should always be 5 bars but ever since I got my phones I was only getting 3 bars max regardless of firmware or rom. I know because I have flashed them all. I have a developers edition and an AT&T edition m9 and both phones got the same reception.
well about a month ago I just wanted to try an experiment so I took my att m9 and changed the cid and mid to match a tmoble version. I then flashed the 1.32 firmware and then ran the tmobile Ruu. As a result I then had a stock t-mobile edition m9. But for the first time I had full bars for my reception!
Naturally I then flashed twrp and put a cutom rom back on it but I had the volte and wifi calling along with full bars reception. So put I that observation in the back of my mind and carried on with my business.
Well recently the tmobile update came out and I just flashed the firmware package that sneakyghost (thanks btw for your firmware files) put up and updated the custom rom I was on. But I noticed immediately afterwards my reception returned to 2-3 bars again. I really didn't care too much but then the rom I was using started acting funny. The developer decided to mess with the cpu cores on his update and in extreme power save mode over night it would eat 10% of my battery. And that is something I can't tolerate...
So, I decided to run the 1.32 tmobile (that's my carrier) RUU on my m9 and then accept the 2.7 ota. My reception then returned to 100%. after that I reflashed twrp and super su and restored all my data.
I told my wife about the reception and she wanted me to do the same on her phone (the dev edition) and so I did and got the same results....
So moral of this long post is that if you have poor reception than flashing an ruu for your carrier just might be the trick. This in return will save battery life.
If you decide to try it let me know if it worked. Thanks
This is the link with instructions on how to change your phone from one carrier to another. clsA gives instructions to convert ATT model to developer edition. But you can change your cid to whatever you carrier is and flash accordingly.
Tmobile cid= T-MOB010
At&T and develop edition cid can be found in the link. Also make sure your mid match the firmware you flash. Tmobile mid is 0PJA12000

I noticed my reception also being worse than my Galaxy S5. In fact, when I woke up I found that my phone was roaming! I never had that issue with the S5. I found it strange. Wi-Fi signal also isn't as good as on the S5. I don't know if it's all the metal or the terrible Snapdragon 810.
I wish your method involved changing something in build.prop lol, that would be simpler and quicker. I'm on a custom ROM also, not by my own will but because I bought the phone like that, I have no idea how to go back to stock AT&T without root and to be able to accept OTAs. I am S-On right now.

There are a ton of excellent guides in the forum to either change ROMs or return to stock. I think you have to be s-off though. When I want to return to stock I just run an RUU. but remember to back up everything you want to keep because the phone will be completely wiped

I can't find any good guide here for the M9. Weird huh? I've been here since 2008, read countless excellent guides for many phones, and let me tell you that in the past guides were clear and informative. Now all I see is people writing random text all over the place, no clear steps, and information isn't always updated. Probably younger people are writing them, no problem, but it's not helping me understand how to do it.
There's a guide that still says that HTC hasn't yet allowed the bootloader to be unlocked for the M9, and yet when you go there you realize that HTC allows us to unlock it now.
Anyways, my point is, I can't find a good guide, it's not that I'm being prideful, it's just that I have indeed searched and can't find a clear guide. I'm not sure if most assume we have to be S-off? In the past people used to mention "you have to be rooted, or unrooted, or unlocked bootloader, or S-on or S-off". Now it's not very clear so I'm confused, especially since those guides have so many links that I don't know what to download and each is 2GB. You're not the first to tell me that xda has many excellent guides without pointing me to one for the M9 haha.
I want a better reception among other things as it worries me that it was roaming out of nowhere and I'd love to go back to stock as I am not a fan of custom ROMs (except for on my 2010 Galaxy S1 lol).
I have to admit this is the most confusing phone when it comes to modding it or removing root to OTA.
I tried to run an RUU for AT&T latest Android 5.1 (when I was running stock 1.32) and it failed many times, even though I unrooted and locked bootloader. I miss the days of ODIN flashing in download mode =(.
I'm happy the ROM I'm using is stable but still.

I can see where you think my guide has a lot of links, but all you need to do is determine what your phone is now and choose the correct link for your device. To figure out your current Firmware just reboot your phone to download mode and it tells your OS version right their.
now you know your version download the one your on now or a newer version and RUU back to stock, It's actually easier than Odin
Read my entire instructions to convert to developer edition and you'll see it's not all that hard.
S-off is a pretty vital step if you plan on flashing your phone much at all, and is well worth the $25 price. But it's not needed if you just want your AT&T phone back to stock. Just lock the bootloader (fastboot oem lock). and Run the RUU.exe and your done you have a stock phone.
If your worried about the modified status you'll have to pay for the s-off to remove it.

Thanks for the answer. I saw yours a week ago and I skimmed through it and since it needs S-Off, I kept it for later. I have a question for you and I'll PM you if that's fine as I don't want to take over this thread.

cLSA is very knowledgeable on the m9. When I first made the swith from Samsung to HTC I didn't know jack. But in the past few months I have realized the m9 is the easiest phone to customize that I've ever owned. If cLSA can't help you (I'm sure he's a busy guy) than I'm sure I could. I'm moving and dont have internet yet (right now I'm typing from my phone) but I can always turn on my hotspot and lend a hand.
First thing I recommend doing is to make sure you're adb and fastboot are updated to the latest version. Also make sure you have ever all the right drivers installed.
I'd also recommend getting s-off. Just makes life easier knowing you can flash anything you want (including older firmware). And if a stock phone is what you want than you can turn it back on
If your adb is working then with you phone plugged in and USB debugging clicked open a command prompt (as administrator) and type adb devices. You should then look at Your phone and grant the phone adb privelages. Following that you should see your phones serial number on your pc.
If you see that adb is installed properly, if not then go back and install adb properly. Pm me if you want me to walk you through anything.
Ive done a lot of reading in regards to this. almost every place I read says other roms should flash on device not of those carriers. reason im investigating this is because CM for sprint has all the sms issues. and after reading through all the tmo roms im not seeing anyone mention sms issues. every time I try to flash another carriers rom it reads that they are carrier specific and fail. is there a way I can make another carriers rom flash to sprint. my device is unlocked, though im using a sprint sim for lte and from what im reading also, its just a matter of an apn setting for sprint, and/or a radio flash for sprint. anyways, comments?

I wouldn't flash another carriers roms. it can make your phone brick and just a paper weight. other carriers have different settings and files that our phone doesn't..i don't know how to explain it better but I don't recommend it

That is kind of unfortunate if that's the case that SMS doesn't work right out of the gate on Sprint CM ROM's then. While I have gotten used to it, it does get annoying after a while having to reconfigure using the *#*#4636#*#* method every time.
I have tried to flash a few other carrier based ROMs via TWRP but they typically fail anyways (which is probably a good thing). I don't think I've ever actually successfully flashed another carrier based ROM through TWRP.

You can't just flash a tmobile rom on this device. It sounds like to me you need to get your phone unlocked to use tmobile sim. I would suggest http://www.idoneapps.com to sim unlock your phone.
I have no idea what you mean by password screen. What firmware are you on? How did you root your phone? Did you turn off reactivation lock?
I can try to help you but i need to know more detail of your problem. And do understand I'm limited on time i spend here. I'll check back when i can.
http://forum.xda-developers.com/note-4-sprint/development/steps-to-install-dr-ketans-rom-g-t3379659 This will help u install N910G roms.. i tried. M6 version of Ketan rom. Working food, but am not on sprint.
just like the title says.
All V50 models can be rooted, and you can see the guide further down in this section. As for carrier stuff, I rooted my Sprint V50 (also on software version 20n) and seem to get VoLTE on a T-Mobile MVNO using some VoLTE fix files from the LG G8 section. I haven't done a whole lot of testing with it yet since it's on a backup line and not my daily driver, but I can provide more details if you're interested. I certainly would like to see more V50 users in the U.S. with working VoLTE.

um yea
we still have one lg v450pm (sprint unlocked) that dont work on tmobile last i remembered.
we wound up getting two s21 ultras for free after 2 year commitment.
i sure liked my v50 better.
expandable storage and headphone jack and no commitment as we owned both
im still bitter at tmobile as u can tell probably so i would love to get that phone working.
can you give clear instructions?
thanks
The general guide for unlocking the bootloader and rooting is linked in the first post of this thread:
https://forum.xda-developers.com/t/...isk-root-using-firehose-by-seasee606.4277273/
There is also a video on YouTube showing how it's generally done:
I also provided some pointers in that thread in post #13 here:
https://forum.xda-developers.com/t/...-firehose-by-seasee606.4277273/#post-85443909
The good thing about this weird procedure is that you can actually "practice" going into EDL mode and using QFIL to look at the phone's partition files without changing anything on the phone yet. You may also want to get used to the button combination to enter recovery mode when the phone is powered off (also mentioned in my pointers linked above).
After rooting the phone, grab the attachment file found in this post from the LG G8 VoLTE fix thread:
https://forum.xda-developers.com/t/lg-g8-volte-fix.4113291/page-2#post-85455109
Using the files inside the attachment and following the included readme instructions, replace the corresponding files on your V50 (make sure you backup your original files first). Then reboot, and you should be done.
One major issue I currently have is that every once in a while, the phone signal just drops off and can't come back (it just happened again today). But after putting the SIM card into a different phone for a bit and then later returning the card to the V50, it works again. This is on a Tracfone T-Mobile SIM card, so I don't know if it's something weird about that MVNO or T-Mobile's network in general. I'll have to look more into this, and I hope this dropping off isn't because of the Sprint V50's IMEI number which, like all Sprint-branded phones, does not pass T-Mobile's IMEI checker.
Hope this helps. If you have any more questions, feel free to ask.
