I decided to experiment a bit and used this rom "http://forum.xda-developers.com/galaxy-s5/unified-development/rom-cyanogenmod-13-0-android-6-0-t3237502" which is CM13 with the experimental 6.0.1 on my S5. Everything worked flawlessly except I cannot use my signal at all. I decided to mess with my APN settings but couldn't get it to connect to no avail. I want to downgrade back to my phones stock firmware (5.0). Can anyone help?
Also my phone model is a SM-900P. Its the boost variant but they're interchangeable between the Sprint/Boost variants.
If possible, I would like to just downgrade back to 5.0, but if anyone could help with restoring my signal on 6.0.1 It'll be greatly appreciated!
Check your APNs

I successfully installed a CM13 ROM for a different variant than my phone. Installed ROM jfltexx variant intended for a Gt19505 model S4 on an i337z S4. It worked and now the device model in phones settings shows listed as GT19505.
ROM works fine, phone dialer functions but I read that I should update the radio firmware. I have had a call or two drop off with no ringing sound but call is apparently going through but I can not hear person on receiving end.
So what baseband modem firmware do I update to? The true hardware i337z or the GT19505 that the phone is working as? I went from Kit Kat 4.4.2 to Marshmallow 6.0..
Baseband Version after installing CM13 jfltexx remains the original i337ztuuboa3. Everything else has changed to reflect CM13 ROM. Build, Kernal etc.
I'm baffled so any help would be greatly appreciated.
I'm suffering the very some issue and few others.
Just noticed that my present baseband is I9505XXUGNF1.
I've downloaded the I9505XXUHOJ2_I9505ITVHOJ1_ITV nd extracted both modem.bin and NON-HLOS.bin and flashed using Heimdall on OSX via cli.
But the phone is still reporting the old BB number.
You need to flash i337z model's RIL files & Modem. Don't know where you will get that but that's what you need to flash for sure..

Thanks. I'll search around. Problem with calls is few
Few. I say 5 % of time usually when I'm going from one area to another so I'm not certain I want to mess up phone. Couple of questions, I am using latest modem for phone as far as I know, bought it in Oct 15,and Cricket has no new update beyond 4.4.4. Are you positive it will not mesd
To flash should I use existing TWRP recovery, Odin. for those file types? I'm guessing Odin.
Once again thanks for your help

Just flash this. http://androidforums.com/threads/bo...al-boost-apn-fix-for-d2lte-builds-mod.840501/ When flashing roms flash any g900p kltespr. And you will be fine. That's all i ever do
Ok im really hoping someone can help me.
Bought a N920F (yup doesnt exist but N920p's have taken a trip to China to be turned into this strange model)
Now the phone was working fine on Lollipop, and model used to show N920V and baseband Sprint it was like a hybrid custom firmware probably hacked up to be used in UK, but download mode etc. showed it was a N920P originally. Now I wanted to upgrade to Marshmellow, before this I made a nandroid backup and also backed up Radio & Efs using app.
Upgraded succesfully with stock N920P and now no network, tried everything. Then thought I could downgrade via flash to Lollipop to no avail as I think its now locked to do so. Nandroid restore not happening as I believe its locked to restore also unless maybe I was on lollipop.
So now im stuck on stock N920p firmware thats not working in UK networks. Im about to give up, is there any solution. Would unlocking the phone in its current state unlock it to UK networks. I hope there is a solution.
Any help to the right direction is much appreciated.
Things ive tried
Downgrade-unsuccessful
Restore Partitions-unsuccessful
Flash N920V-unsuccessful
Full restores etc-unsuccessful
nandroid restore-unsuccesful
Kind Regards

Check if there is a service menu in your settings
It should be named "activate this device"

now the 920p firmware is locked out of the box if it was unlocked sometimes certain rom flashes will relock
as prev poster said activate device is for sprint users only will never work
have you tried to goto network settings and making sure its set for global or automatic.
also is it saying invalid sim or anything like that normally first signs of being relocked.
i paid 34.99 for a unlock from the idone app worked great.
I've been looking all over the internet to find the stock firmware to flash in order to get back to stock on my S8+ and haven't found anything. Can anyone help me? I made a mistake along the way with rooting using the SamPwnd method, phone boots but I just want stock.
here you go i had the same issue haha
http://updato.com/firmware-archive-select-model?record=90229397555E11E7963AFA163EE8F90B
i have used this on my device it does work
did it work?
I flashed the G955U1 firmware from the UCS version and everything works fine, actually its working better than the regular stock firmware cause this U1 firmware is so smooth: data works, calling works, and i can receive texts but i cant text anyone else. Could you help me with fixing my texting problem? I'd prefer to stay on the U1 firmware hopefully.
Will this work on s8 smg950u from xfinity?
I bought this phone recently and immediately jumped into the rom scene to see what stock roms I could load up. I have tried Ressurection Remix, Carbon, and Lineage. All three of them refuse to make or receive calls when I'm on LTE; from what I understand from searching through the forums is that it might have something to do with VoLTE. I tried to disable it via build.prop but nothing changed and as I mentioned prior attempted to install other roms. I'm going back to stock for now because it makes little sense to only run the phone on 3G only in fear of missing calls.
Model: FRD-L14
Carrier: MetroPCS (It shares the same network as T-Mobile)
Any help would be greatly appreciated.

Honestly your best bet would just to stick with stock for now until the main Developers get more things fixed because no custom ROM supports VoLTE and there have been numerous reports that T-Mobile has a problem with custom roms.
