Interesting. How are you getting into the test menu by the way? (The one where you see network status, can select LTE/WCDMA/CDMA, etc, and see VoLTE provisioning and whatnot)? *#*#4636#*#* hasn't been working for me -- is it working for you?

What does it show under About Phone -> Software Information -> Service provider SW ver? With mine, original HK on HK firmware now, it shows TGY/TGY,TGY/TGY

Was all this caused by odining the HK firmware once?

I had a weird thing happen where, out of nowhere, I can now choose to enable VoLTE on my Japanese sim card (not CDMA) when I couldn't do it yesterday. I had been switching to every CSC I could think of to test how CDMA worked, but couldn't get it working, at all, in any of them. I tried CHC, TGY, OWA, OWO, OWB, OWT CSCs but had pretty much the same result. Chinese/HK ones show my MEID alongside my IMEI but don't seem to attempt to connect to CDMA. Non-Chinese/HK ones don't show my MEID at all, and don't try to connect to CDMA at all either.

I'm not in the US right now so I don't have a way to check with a Verizon sim, but with a Japanese CDMA sim. When I was in the US earlier this month, though, I tried several CSCs and couldn't get any kind of connection to verizon whatsoever. So if you solve it or find anything new, let me know!

Update: Even weirder -- I tried moving the sim which gave me VoLTE options to Sim 2 slot, and it didn't anymore. Then I put it back to SIM 1 slot, and it also had stopped offering VoLTE as an option. I guess I may have lucked into a bug which allowed VoLTE to be set on an unsupported carrier? No idea. Really wish I understood the conditions under which it shows the option. It seems I may have to factory reset several times to understand it, though, which is something I definitely don't want to do.

Is TWRP like so completely slow that it is basically unusable for anyone else? Is there a work around or should I try fixing it?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
I use the App shortcut master light and select app explorer and select the Settings app and pick RadioInfo.

Another one that used to work for me using shortcut master was the "'Hidden Network Setting" app and selecting Main Activity.

In the hidden network setting you can select what bands you want to use, and before when I got Cdma working I saw the cdma bands listed. Now I only see GSM, WSCDMA and LTE bands. Arg.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] duraaraa:
Thanks. I can confirm I also see nothing about CDMA there. But CDMA wasn't ever working on my phone, even out of the box.

If we can figure out what you did to make it no longer show up, let's hope we can figure out what to do to make it show up again!
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
Can anyone confirm that flashing the Combination rom in the OP will allow you to flash any snapdragon variant combination rom like the unlocked sm-g965u1? Cause that version should have the cdma radio enabled.

https://xdaforums.com/galaxy-s9-plus/how-to/sm-g965u-sm-g965u1-combination-files-t3765760

Last I tried flashing the combo rom I didn't have the Odin repartition checkbox checked which the OP said might me needed so I will try when my RMM is no longer pre normal. Because I'm pretty sure I need that to be Normal before I flash stuff in Odin right?

Is the Z3X Samsung Tool Pro needed to flash the combination Rom, or can we just use ODIN? Most sites Ive seen that let you download download the Z3X tool look like virus download sites. It looks like ver 32.1 is the latest that supports the galaxy s9.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
From my brief analysis of stock firmware, you need to flash a version of stock that comes with the OWA csc package. CSC_OWA is in the CSC filename, not CSC_OWO or anything else. Most sites that provide zips of firmware have their contents listed somewhere on the download page
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
Do you have an example of a CSC that has this "OWA csc package". Unfortunately I can't follow what you are trying to say here.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
Its pretty close to unusable but the only option we have so I'm not complaining. I disabled sleep mode which seemed to help because I had great difficulty trying to slide that bar to the right to unlock. It would be awesome to get a cleaner version.

I wish the OPs kernel supported wifi or if we had some other stuff to flash through twrp. I'm still trying to get root and getting cdma working again.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
Here is the zip of firmware I was running until rmm prenormal finally reset yesterday:

See the 3 capital letters after CSC_OMC? that is the "name" or some other kind of identifying symbol on that particular group of carriers. I originally flashed this bundle because there is one for puerto Rico they are still on v1, so when I needed a v2 I picked one that Dad the same CSC and it worked exactly like the first one did.

I highly suggest you study up on the naming conventions Samsung uses for their firmware as it will yeild very useful information when trying to figure out what to flash at times like this
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] bigmaster:
Hi, I have the SM-G965W model on Rogers' network. Could you please enlighten me how you have unlocked the bootloader option?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
Sure, here are the steps:

- find box your device came in

- put phone in box

- return phone to store or carrier where you bought it[

- OR: sell device used on swappa or ebay

- buy sm-g9650

- wait 7 days

If you would have read any of this thread or the dozen or do others on here, you would have read that none of this is for your device
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] duraaraa:
There has to be something apart from the firmware. I tried exactly the one you said as well as every other csc I could find but the inability to use cdma persists across all versions for me.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
One other note(s), I dont think I ever got cdma out of the box on the 2 CSC versions that previously worked for me. I had to always first put it into 2g/3g or even GSM mode for it to initially register with the network, and only then could I set it to the default 4g/3g/2g mode and I would then get LTE as well as cdma access. Sometimes it would take all night leaving the phone on overnight with the screen on, and disabling wifi. It seems that the band modes of GSM only, WCDMA preferred, etc dont always line up with the true bands being enabled...
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] duraaraa:
Weird! I'm a few installs away from having tried every CSC in existence, so I'll give leaving the phone on for a long time a shot...
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
Yes, terribly weird. Here is the extremely random case I'm dealing with now in LTE/CDMA mode. My SIM is really MCC 311/480 and shows that way in the Auto PRL mode but for some reason in LTE/CDMA mode it gets set to 310/003 ... which is another Verizon combo I'm guessing. So my LTE data works fine, but no voice service. I have no signal bars but in reality I have a decent signal.

Maybe with root I can change the default MCC/MNC somehow? I think my phone reports out of service because this is set wrong in the phone somehow and not paying attention to my SIM properly?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] alex.do:
[MENTION=3463480]travis82[/MENTION] I know I may become annoying but it would be great if you could share the how-to steps. all i want to achieve is just stock ROM with root (by magisk). and by the way latest FW for this variant is now G9650ZCU2ARE6. you may already know and having it updated by now.

Failed Magisk 16.4 install with Magisk Manager/ODIN method

It looks like we are missing some instructions ... I just tried installing the latest magisk beta 16.4, patched with magisk manager and flashed with ODIN on my Hong Kong CSC version. Everything went great until I got the "Verification Failed" message when it was booting after the flash. Pretty sure I was hosed at this point ... but maybe not .. I went ahead and agreed to reset my device knowing my RMM would be tripped and it rebooted ok .... Pokemon go wouldnt run so I thought I may have Magisk but NO!!! It wasnt detected, thought I would reboot for the hell of it to see if it removed verity ... NOPE!!

It says Only official released binaries are allowed to be flashed with a security error Bootloader'ish warning saying my phone is locked. Rebooted bootloader and verified RMM status is prenormal again. Attempted flashing Combination Rom with re-partition checked, and it Failed ... details below.

It looks like I may just be hosed, I can't re-partition in ODIN 3.1.3.1 ... it tries to start but ODIN turns on the Red Fail Flag and nothing happens. Happens on both the Combination ROM and the Panama build Im trying to roll back to again. Wonder if I have to be RMM normal to re-partition?

<ID:0/008> Odin engine v(ID:3.1301)..

<ID:0/008> File analysis..

<ID:0/008> Total Binary size: 6657 M

<ID:0/008> SetupConnection..

<ID:0/008> Initialzation..

<ID:0/008> Set PIT file..

<ID:0/008> DO NOT TURN OFF TARGET!!

<ID:0/008> Can't open the specified file. (Line: 1892)

<OSM> All threads completed. (succeed 0 / failed 1)

So either my phone was hosed from the beginning because I never had re-partition checked or we are missing some steps like we may need TWRP installed to install magisk regardless of whether we use Odin or Twrp to flash it.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] travis82:
When I borrowed the phone I did this.

1. Crom apk flashed launched unlocked.

2. Dev options oem unlock.

3. flashed twrp.

4. rebooted in to twrp and formated data to remove encryption and factory reset in twrp.

5. installed rom.

6. if magisk is not flashed with rom flashed magisk.

That's it that's all nothing more nothing less.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] alex.do:
So you didn't flash kernel? After flashing magisk you will need kernel for magisk to patch it?

And doing this won't trip knox, will it? On s8 forum there's an official TWRP thread, the OP says flashing custom binaries will trip knox for sure. that's why im asking, just wanna make sure..

Thanks for the response.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] travis82:
As soon as you flash a custom rom and sometimes even twrp, knox is tripped.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] alex.do:
thanks for the confirmation [MENTION=3463480]travis82[/MENTION]. this guy above confused us all.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] duraaraa:
I've never unlocked the bootloader or tripped knox, and choosing repartition in Odin has always caused the same error for me.

I'm guessing you need to specify a PIT file when you choose repartition, maybe?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
This error is from your PC, not your phone. Odin can't read the file it's trying to flash, probably due to permission denied
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] duraaraa:
Not so sure you're right about that. I have the same error, only when repartition is checked. Does repartition work for you?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
I was running your ROM/kernel combo fine a month or 2 ago but the lack of WIFI made me switch. I'm pretty sure we need your kernel as well right? I'm pretty sure it didn't work for me unless I flashed your kernel. Or am I mistaken and the ROM has its own kernel with potentially working WIFI?

Operators and APN

I just got this model off Amazon. My goal to use my company SIM (Verizon) and personal (T-Mobile). First day I used with just TMobile SIM and worked great. Next day I inserted my Verizon SIM too and at first it wouldn't connect. After playing with airplane mode, turning Sims off and on, and restarting, the Verizon one finally registered. But now my T-Mobile SIM is stuck roaming on at&t in places I know I have coverage. Also now my option to select network operators and APN settings are now gone. Any input on how to get them back or fix this issue? Thanks in advance.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
I dont have the dual sim model so i have no idea how that works
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] xK31THx:
I thought the same thing, and mistakenly ran the ROM with the kernel (sans wifi) for a few days, but then decided to flash the ROM again without the kernel, and WIFI DOES WORK WITHOUT FLASHING HIS KERNEL. I Have found the ROM in the OP to be very stable.:good:
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
Awesome, I wonder if you need the kernel to do the initial flash and wipe data etc, and once you get a booting system go back and reflash just the ROM. That will be a freaking miracle if thats the case!
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] xK31THx:
Someone will surely correct me if I'm wrong, but I don't believe you need to flash the kernel at all. I only flashed the newest HK (TGY) firmware (downloaded using the Samfirm application), flashed TWRP, followed the instructions to flash the ROM, and ended up with a fully functioning OS. BTW, I have the Chinese SM-G9650 DS (dual sim) model (because I bought it here in Shanghai).
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] JDougherty77:
Not sure if there's any certain method to this, but I took the Sims out, switched TMobile to slot 1, it then registered properly but then Verizon wouldn't in slot 2 but my APN and network operators options returned. Switched them back around again (Verizon in slot 1) and restarted the phone and both registered properly... And then the APN and network operators disappeared again. But it seems it doesn't auto switch networks for roaming coverage anymore and you need to be in a good coverage area for both Sims to register properly.

Can you already be root?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
I've seen that error dozens of times and every single time it came from Odin being unable to read one of the firmware files I was flashing at the time. It's possible that whatever you are doing is broken in the version of Odin you are using, but regardless I'm absolutely but wrong: that error is NOT coming from the device, but from the software running on your PC.

Take apart the binary and see for yourself if you must, but choosing not to believe me dosent change the facts at hand
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] duraaraa:
I agree that the error is coming from the software. But I am not so sure the reason is file permissions.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
Will try and do a disc scan on my laptops 512GB SSD at some point but its very strange that the same exact file flashes "fine" in ODIN with the repartition box not checked, but when its checked I get the error fairly quick
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] travis82:
ITS ODIN, stop wasting your time thinking its your laptop. Try odin 3.13 or 3.12 one of those versions. It does work so its a user error on your end and no its not you have a bad HDD but possible you got a corrupt download.

I also updated the OP with new Firmware and maybe later I will update TWRP if I get the time free. Again I do not have this device yet so my apologies if its not 100% perfect.

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] partcyborg:
So don't check the repartition box. Odin does the right thing if you give it an archive with a pit file in it anyway. That check box is irrelavent and uselss anyway.

In fact, this entire exercise is completely pointles, as the partition sizes never change anyway, so your putting huge amount of time and energy into doing something that does nothing. Just forget about the put pit file and move on

Looking for the exact ODIN version to use now

Thanks, I was kind of joking about scanning my drive, pretty sure the issue was with ODIN. Will try to re-download your ROM but I was getting the ODIN re-partition error on a couple other CSC's so the user Error here is me using the latest version of ODIN which I thought we needed that is linked in the TWRP thread for the exynos versions. I guess we only need the older version for re-partitioning then? Or do you recommend using ODIN 3.12 / 3.12.5 / 3.13 for everything?

https://xdaforums.com/galaxy-s9/samsung-galaxy-s9--s9-cross-device-development/twrp-exynos-t3763464

Was literally going to post this question about what ODIN version to use after I saw this site with a decent write up using odin3_v3.12.5 to flash the Combo Rom.

http://www.teamgsmedge.com/2018/03/rom-combination-sm-g9650-u1-samsung.html

Do you only recommend re-partitioning if all else fails? Or do you recommend we always use it?

Thanks again for your time and posting the new version of your ROM.

[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] beachmiles:
Someone in this thread recently said that if you flash just the ROM in the OP that the WIFI is working. So I'm not sure what the kernel in the OP buys you, but I suspect you need it to get the ROM to work initially? Then you can re-flash just the ROM and you may be good to go?

I'm waiting for my verity prenormal to go away before I try to give myself the best chance for success. Not sure if this is needed because it seems my bootloader remains unlocked through the various CSC ODIN flashings I've done.
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] travis82:
You should be able to flash what you want with an unlocked bootloader. The custom kernel seems to be ok building wifi. Also maybe a flag/prop needs added to allow wifi to kick on. We all know samsung needs extra props added to custom roms to make them work correctly. If you ever owned/dev a samsung before you know exactly what I am talking about.

I tried this with Hong Kong dual sim version. Although it was possible to enable OEM unlock, It was not possible to run CROM (unknown error) and it's not possible to flash anything other than stock firmware.

Any idea? I guess waiting for RMM to return to something other than prenormal will fix it?
[Samsung Galaxy S9 & S9+ (Snapdragon) ROMs, Kernels] travis82:
RMM Status should be off. If it's rmm status : prenormal you can not flash a thing except official binaries. So you have to wait a week or until someone finds a fix.
