MY network doesn't work.After i flash the data fix it recognizes for like 10 seconds then drops and i cant make a phone call says not registered on network.It does recognize my my ph# in setting though.

Also to fix the dim display turn off Always on display.
[Sprint  Galaxy Note 4 General] aaron74:
I heard peeps can't get Sprint service? So maybe?

For anyone with Sprint service. I might have found solution. I can't test cause I use gsm. But anyhow if you install an app that will allow you to edit your radio, like idoneapps or whatever you like. Cause I noticed mine was on wcdma by default. Maybe try changing it to lte/gsm/cdma auto. Which is where it should be for Sprint service.

Just a suggestion.

Plus it looks like the build.prop might need some editing.
[Sprint  Galaxy Note 4 General] aaron74:
Sprint service?

you guys get this working with Sprint service yet? If not, ive made progress getting it to work on Norma note 7port. But text don't work yet. I'm working on it. I'd like to see these rom's work for Sprint people. Here's a data fix i made for this Rom. If someone with Sprint could try it. Let me know if works? Thanks.

Just so I don't step on anyone's toes. This data fix original came from [MENTION=2685386]louforgiveno[/MENTION] here.

But I replaced and edited most the files in it with pg1 files.

[MENTION=6195198]aaron74[/MENTION] i tried on PG1 FW/BL. it boot fine with your data fix. x-rom data fix gave 4G but keyboard fc (customer.xml file) while the other data fixes gave 3G. Data work better on x rom data fix. none of the data fixes are we able to send text. From what I can see, the network option are GSM, we need the one that can allow us to select CDMA/LTE which what made it work for US Sprint on Dr K M6 rom for example. Hope this help.

There is someone calling our for tester to test datafix for our N910p at Norma N7 v5 thread.
[Sprint  Galaxy Note 4 General] aaron74:
OK try these steps and see if it does anything.

1. Download "Phone Info Samsung" app. I can't get link. Download from play store.

2. Open it, click menu button.

3. Select hidden codes, goto 4636 and select 1st root option. If Testing menu doesn't pop up. Try it again. You should get menu.

4. Select device info and change radio to "lte/gsm/cdma auto"

See if this sticks. Pics below

If this don't work, we might need another kernel or csc files need edited.

What kernel you using? One that came with rom or H-vit for 910f?
[Sprint  Galaxy Note 4 General] aaron74:
We all should get together and start a special thread on sprint to figure all these data fixes out and put them together.

I got some know how (a little), and some ideas. But my down fall is i don't use sprint service, (I'm unlocked and use cricket/at&t). so it's time consuming to try every little change with some one over the net.

These roms work good for me. I'm just trying to help out and get sprint people going good.

Just let me know if i can do any thing. Thanks.

[MENTION=5695250]shadowcliffs[/MENTION] [MENTION=1919231]KLPFL[/MENTION]

I think we're gonna have to dig deeper to get cdma working. If we look at an earlier post from [MENTION=1503720]tx_dbs_tx[/MENTION]

here.

He is a very good developer with these sprint roms. And his post sums it up. Maybe i can decompile the framework and see if i notice anything.
[Sprint  Galaxy Note 4 General] KLPFL:
Yeah.. i am in his hangout. He is trying to port the n7 rom for sprint but he is very busy.

Strangely whatever Lou did to verizon for the n5/s7 port it works for us sprint user

---------- Post added at 02:43 PM ---------- Previous post was at 02:39 PM ----------

The rom run great just the hick up is sending text
[Sprint  Galaxy Note 4 General] aaron74:
Maybe try comparing all the csc features in /system/csc/others.xml with our stock one. Look for all 'ril' 'messages' and 'cdma' lines. Try adding and swapping what makes sense. A good Linux program 'Meld' is great for comparing files, think they have for Windows too.

It's a lot of trial and error and flashing. Time consuming, but I've gotten allot of stuff done that way.

Also, I'm not a sprint user, so i don't know alot about there service, but i notice these roms don't have the sprint apps, like sprint extension and such. Do they have anything to do with it?
[Sprint  Galaxy Note 4 General] KLPFL:
There is only two Sprint apps that are link to Sprint but I don't remember... I am not a computer or code wiz at all
[Sprint  Galaxy Note 4 General] shadowcliffs:
I agree with your guys: there is nothing wrong with the current datafix file, it's the rom, i.e., Norma N7, Aurora or X-Rom, because I just used the datafix file on Noble rom 3 and sms/mms works fine. The obvious difference is in the settings of preferred network type in mobile network. Norma/Aurora/X-Rom all have something like LTE/3g/2g, instead of LTE/CDMA auto. It means those GSM based Rom is not ready to be a CDMA phone, at least not from the settings. I used an app called Mobile Network to set the network type as LTE/CDMA auto, but I guess that still doesn't switch the phone to CDMA.

The easiest fix is to use a CDMA ready rom (rom ported from stock Verizon or Sprint rom).
[Sprint  Galaxy Note 4 General] Droidman61:
I finally got the X-rom working on my Sprint Note4 CDMA, although it only shows 3G. But I can send and receive messages, and have wi-fi.

I can't post the links but this is how I did it.

1. Install X-rom v3 don't let it boot up. Go back into recovery and

2.Install Emotion-TW-stable-MM-r26-RC1-SM-N910F_N7port2 kernel, don't let it boot up. Go back into recovery and

3. Install HighOnAndroid-N910P-APN-SMS-DataFix. then

4. Install FIX_AutoBrightnes_v3.

Let boot up, and everything is working. Don't know how it is LOL but it is. :victory:Hope this helps I know it has been very frustrating for me. :victory:
[Sprint  Galaxy Note 4 General] Droidman61:
Could not get it to work on any other, just X-rom v3. One or the other would not work either wi-fi or data.

Had anyone else tried Norma V6?

Cause I tried it last night, with h.vit kernel, and my phone got so hot trying to boot up. I turned it off and rebooted into twrp, and it reported 70C. So i quit and reinstalled my stock backup.

Anyone else have similar experience?

Edit: The 70c is irrelevant, twrp shows that normally. But this phone was super hot. But by using Ram kernel for 910p took care of this. Everything good
[Sprint  Galaxy Note 4 General] KLPFL:
Have you tried RamKernel? It's doesn't give hotness compare to H-Vit on my phone... It does boot up on my phone with F or P variance but I have to wipe caches after install the kernel. if I'm not mistaken, Norma rom has RamKernel built in.
[Sprint  Galaxy Note 4 General] aaron74:
I always thought we had to install separate kernel.

So you are saying i can just flash Norma zip and reboot?

Or should i manually install ram after?

Thanks.
[Sprint  Galaxy Note 4 General] KLPFL:
From what I can see, as of V4. Sing pre-implement RamKernel in there. I installed Norma V4/5/6 without the Kernel and it booted up fine. The only different between your phone and mine is you are using GSM and I'm using CDMA.

---------- Post added at 03:40 PM ---------- Previous post was at 03:38 PM ----------

Ram aslo created for the P variance too as well.
[Sprint  Galaxy Note 4 General] aaron74:
Thanks.

I've always thought we needed h.vit to boot on our device.

I misunderstood info from past.

I'll try just the zip, see how it goes first. Then maybe after install kernel for our P model.

:good:
[Sprint  Galaxy Note 4 General] aaron74:
[MENTION=1919231]KLPFL[/MENTION] Thanks again. Ram kernel runs way way cooler. I finally got it all working. This v6 took me a while to figure out how to get data. It was others.xml, had to erase.

I finally got moved and I'm getting settled into my new place. I hope to get back on my Sprint N7 port very soon. I have the Sprint N7 rom running beautifully on my Sprint N4 but i run out of time and had to pack up for the move. Man I'm sooo close to finishing the rom. Stay tuned folks. LOL

Yes the Sprint apps are crucial. Also many of the csc features in others.xml, etc are the same between the Sprint N7, N5 & N4, however there are some network/features that are different and/or not compatible between these devices. I have already done this in my port and it's just a matter of me finishing the rom.

Correct. GSM and CDMA (especially Sprint CDMA) is setup different in framework, system apps, etc. You will never get an original GSM rom to run correctly on a CDMA device. Period.

I have my Sprint N7 port booting and running beautifully using the original stock (slightly modified) kernel from Samsung. So it's not a must to use one of the other kernels. I try to keep as close to stock as possible so I decided to give the stock kernel a try and got it to boot successfully. It only needed a few edits in ram disk.
[Sprint  Galaxy Note 4 General] shadowcliffs:
Can't wait. That will be the Rom for my N910P.
[Sprint  Galaxy Note 4 General] aaron74:
Awesome, :D

I don't even use cdma service. But I always look forward to your Roms. They always install and work flawlessly. I'd rather install a ROM made for my device and then get GSM working for myself.

PS, I feel for ya, moving is such a pain in the a$$!
[Sprint  Galaxy Note 4 General] phonetec:
Any prerequisites for your new rom? Like firmware version, baseband?
[Sprint  Galaxy Note 4 General] tx_dbs_tx:
Yes. I used the Sprint N4 PG1 base files for the port which means you will need to fully update your phone to the PG1 software, modem and bootloader. If you're on the newer PH4 software I would try to go back to PG1 as it doesn't have the safetynet root check stuff. I will post updates to the status of the rom once i get it ready. It shouldn't be too much longer.

FYI: In the future I will not be posting here in this thread concerning my rom as it is a completely different rom for a completely different network.

Full disclosure, I was provided this unit by RavPower in exchange for an honest review. The first thing I noticed about this charger was the weight; it a heavier than my other chargers but in a good, sturdy way. The folding plug feels very solid as it snaps into place, and overall the construction seems very good. The size is nice and small, perfect for throwing in your laptop or travel bag. As far as charging goes, it offers USB C charging at a max of 29w for devices like a MacBook. With my Nexus 6p it was able to deliver nearly the full charging speeds, registering at over 2900mAh using Ampere. One thing I noticed is that this charger seems to have less lag than other aftermarket chargers I own. It quickly ramped up to full speed and stayed there.

The Type C port offers max charging speeds of 20V 1.5A, 15V 2A, 9V 2A , 5V 3A max, while the iSmart port will deliver 5V 2.4A max to legacy devices like your tablet or iPhone. Overall I am really impressed with this charger. It's nice and small, offers solid build quality and most importantly has great charging speeds.
[Nexus 6P Accessories] jisddwqs:
Is it compliant? Many cheap type c chargers completely violate the USB Type-C Spec now.
