I don't have a Verizon device but what I will do is I will go to a Verizon reseller to see if I can use vzw network with the att device flashed to XAA. And to see if that can Send msg. Just to see if I can reproduce the problem.

Then, if in your network mode, there is only LTE. I suspect that u actually lose band. In Canada version. They have full band for LTE and WCDMA. But they don't use CDMA or EVDO. That might be the problem.

When people under this thread switch from 950w to 950u, they don't actually lose any data. That might be the case. Maybe the band limitation information is still from G950w. This is also a guess.

So if I can get connected to vzw CDMA network, it is the clue that the firmware actually unlock bands. If I can not do that. I am pretty sure that the band in the switch back phone is still the 950w version.
[Samsung Galaxy S8 Guides, News, & Discussion] Bladescarr:
Anyone tried flashing this yet?

Anything interesting happen?

I cant do it because I dont have a Plus model.
[Samsung Galaxy S8 Guides, News, & Discussion] sniper7kills:
I can't fund my account as I don't have any payment methods they accept... If someone can fund their account to download I'll flash as a test. (It looks to only be ~5 USD)

Stop posting links to that garbage.. someone tried already with their G950XX firmware and it was for some old device, was not at all what was advertised

+1 to having issues with texting, its mainly receiving mms (pics and group messaging) on tmobile.

tried the odin but the phone was still XAA, reverted back to XAC to test the messaging issue. this kinda sucks lolol
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
I am telling you lol, no coma bands are accessible.. calls, receiving sms and LTE data all work just can't send sms..

Also there is no way to get back to vzw it remains stuck on xaa/xaa/vzw no matter what I flash, how I flash, what I wipe, what Odin I use etc

---------- Post added at 07:21 PM ---------- Previous post was at 07:20 PM ----------

Yea, cannot for life of me get back to xac/vzw/vzw which I think is what we need
[Samsung Galaxy S8 Guides, News, & Discussion] thatotherguy..:
your talking about this one
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
To be honest throwing the userdata in an ap slot and flashing works just the same and it flashes it to the user data partition
[Samsung Galaxy S8 Guides, News, & Discussion] thatotherguy..:
yes I know but still doesn't let you change carrier
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
can you upload that ODIN?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
I don't think it's as simple as everyone thinks.. we can essentially flash everything already as it is including user data partitions from other carriers but in my experience it still does not switch entirely..

For example switching to XAC has in effect removed my ability to send SMS and effectively no way to switch back to full VZW as I am now stuck on XAA even after flashing vzw user data and all other partitions

Lol we'll see if he's all talk

---------- Post added at 07:48 PM ---------- Previous post was at 07:42 PM ----------

You guys do know that is the same site one already spent 100$ to buy similar firmware for the G950U and it was files for like a G920T (2 people actually purchased it) and they both didn't get the files right away and had to email them to get links then have them be completely wrong files so they then had to get refunds..

Point is that site has negative credibility and most likely a waste of your time and money as it has been already proven to be posting crap files

but its confirmed that this issue only happens on verizon?
[Samsung Galaxy S8 Guides, News, & Discussion] bossg4:
I would concur, tried flashing my T-Mobile to Verizon. Using non home csc it flashed fine but was still T-Mobile. Flashed home csc and had the error at 32%. Certainly seems to be something missing. :(
[Samsung Galaxy S8 Guides, News, & Discussion] Whanksta:
Why did you guys flash back to vzw? I went from vzw to xac and everything works perfectly.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
i wasnt able to send sms soon as i switched to xac lol thats why i was switching back.. xac essentially removed my cdma option in mobile networks and it would only connect to lte/3g/2g.. therefore everything worked but text messages and no possible way to convert it back to vzw..

long story short i spent 5 hrs yesterday trying to make it work doing dverything imagineable to no avail..

i just spent 3hrs in a verizon store and of course they couldnt figure it out lmao so i got a new shiny s8+ and all new accessories haha.. not to mention i was able to get black like i originally wanted! thanks XAC firmware lmao
[Samsung Galaxy S8 Guides, News, & Discussion] mweinbach:
do you have the binary. it looks like it is missing the latest version.
[Samsung Galaxy S8 Guides, News, & Discussion] Whanksta:
Interesting, now we have a definitive way to swap return cdma phones LMAO

yea but warranty exchange you dont get a brand new device.. only if its doa which is within 14 days

Has anyone, stupidly, tried to flash any of the ENG BOOT and/or new firmwares with re-partition enabled? I understand it is known not too but who knows, maybe we should try.
[Samsung Galaxy S8 Guides, News, & Discussion] ashyx:
Why not flash stock with nand_erase? It wipes internal storage and has been know to fix issues.

I've done it with several devices. Never an issue.
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
Actually I just bought and downloaded it. It is for G950U but it is a much older firmware. There is 0 bloat in it but I can't see any difference from that compared to the XAA version I was on before. I double wiped before flashing it. But the service provider SW. is the same after I flashes it.

Only one thing interesting and I think it is worth to share.

The binary size of XAC and the XAA firmware is ~6G but the Vzw and TMB we got is ~4G. The difference is on the user data.

Anyone want this XAA old firmware? I can upload it to a gdrive

link: https://drive.google.com/open?id=0B9HLoiZFSSSVa1VFaWItV0pxX3M

(This is the link of XAA firmware, use with care)

tell me if this can unlock CDMA band? actually When I got to Verizon. They refuse to give me a sim and test if my phone is compatible..
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
question is, is it eng firmware or just yoyr basic xaa firmware? we already have that and more if that is the case and you just wasted $ as it is free lol

i am assuming its larger because it probably contains files for all the carriers to make it work vs. carrier specific only has data necessary for that carrier to work
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
It just the basic one.

Do we actually have XAA firm before? I think this might do something the same as the XAC firm. As XAC firm is unlocked Canada version and no carrier in Canada actually have CDMA network. So I would like to see if XAA version firmware can unlock some CDMA bands for my GSM phone lol.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol every usa firmware is xaa minus the carrier specific partition

---------- Post added 7th May 2017 at 12:01 AM ---------- Previous post was 6th May 2017 at 11:58 PM ----------

if you flash carrier specific to xac then back you willl be on xaa..

before i really messed up my phone it read xaa/vzw/vzw but when i really messed it up it read xaa/xaa/vzw and had no cdma bands.. that was before you purchased and downloaded that firmware..

so it was already possible to be on xaa
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
OK, my question should be. Is there a chance that we can flash XAA firm then got our device to be the US Unlocked sold nextweek? In this case, we are able to switch carrier freely.

It seems the odin right now can not get the userdata flashed properly.

When I am trying to flash the vzw firmware, the binary size would increase when I added AP CSC etc. but when I added userdata(which is around 1.8G), the binary size wont change. Then It stucked at 4G.

But if I use XAC firmware or XAA firmware, the binary size would be 6G. though in those firmware there is no userdata tar at all. This might explain why you can not switch back to vzw. As the userdata never successfully flashed in ?

---------- Post added at 12:07 AM ---------- Previous post was at 12:04 AM ----------

If we can actually be on XAA, then the CDMA band should not be lost. As the unlocked US version should actually support all of the carriers. I don't have a Verizon sim so I can not test it. I really hope someone can flash to XAA and test if all bands can be unlocked.

Then If CDMA can not be used on xaa/xaa/vzw, then service provider sw. should not be a flag telling us if we successfully flashed the band. because XAA version (US Unlocked) should have all bands.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
if userdata nvr successfully flashed in it woukd still be on the device cuz thatd mean the odin flashes didnt touch the userdata partition
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
My guess is that:

The XAA and XAC firmware use some tricks and let the odin reset the userdata, that's why the binary size is bigger. But the odin we got with the userdata field can not actually use the userdata we provided.

It is just a guess.
[Samsung Galaxy S8 Guides, News, & Discussion] sirjes:
Those with verizon problems, tried downloading the verizon text message app and using that?

Don't worry...soon as it downloads I will be flashing and letting you know. Lol
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
So I was just doing the steps that I did on my S8+ and got my SO's S8 to XAA/VZW/VZW and discovered that if you factory reset the phone, it reverts back to Verizon.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
i factory reset mine probably 10 times or more within 5 hours last night lol didnt work at all for me
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
Didn't work for me either. At least 10 factory reset. Got a replacement today. Will wait until I see proof that cdma will work.

willing to throw in $10 for successful root
[Samsung Galaxy S8 Guides, News, & Discussion] sd_N:
So did anyone flash the XAA firmware the guy posted above???
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
Interesting. Here are the exact steps I took to recreate XAA/VZW/VZW on my SO's S8:

1) New vzw S8, didn't set it up, just skipped all steps.

2) Activated dev mode and used "adb reboot bootloader" to go into download mode

3) Flashed XAC firmware with non HOME_CSC

4) Set up phone normally; however, for security I only enabled pin + require pin on reboot. Enabled dev options again

5) Used adb reboot bootloader to get into download mode and flashed HOME_CSC only

6) Restarted and used *#2263# to get into the band selection menu, tapped enable all bands and hit apply

7) adb reboot bootloader and flashed VZW firmware, but used HOME_CSC for the csc file.

8) It takes about 3-4 minutes to reboot after entering pin for decryption

That resulted in the S8 being XAA/VZW/VZW with everything working properly
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
post ur pledge in the bounty thread lol

---------- Post added at 04:07 AM ---------- Previous post was at 04:05 AM ----------

maybe thats the issue as i didnt do dialer codes to enable all bands.. i am not willing to try on my new s8+ tho haha.. personally u can disable all verizon bloat so its essentially bloat free
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
Maybe I will try again after someone else confirms working cdma. I did enable all bands, but didn't see a difference, so maybe I screwed that part up. I am really missing Samsung cloud, caller id, device manager and other things that verizon disable. Bluetooth worked better on XAA as well.
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
For anyone that has messed up, have you tried resetting the device with Smart Switch? I remember back in the day KIES had an emergency firmware re-initialization option.
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
I did use Smart Switch emergency recovery tool, but it did only restored the VZW bloat. Was still on XAA/XAA/VZW.

So were you able to connect to CDMA or just LTE?
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
Something might help. Test carefully.

Like what I said before, S8 in China dont have any sim lock and China telecom supports CDMA. Anyone wanna try the Chinese version rom?

I post it here if you guys wan to give a shot. Feel free.

They use snapdeagon as well btw.

https://drive.google.com/a/bucknell.edu/file/d/0B9HLoiZFSSSVZE1LcjdETXBiS00/view?usp=sharing

[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
Do you know if the Chinese ROM has google playstore?

---------- Post added at 04:10 AM ---------- Previous post was at 04:05 AM ----------

Craya, was CDMA working on XAC after you enabled all bands? Also, am i correct to assume you did not flash the VZW userdata file when you flashed from XAA to VZW?
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
No, I wasn't able to get a signal nor edit my APN settings with a verizon sim with XAC, even after enabling all bands in the service menu.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
yes i tried that as well as the verizon repair assistant
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
I returned my messed up S8+ for an S8. Downloading the 950W and 950 Verizon firmware now. If I drink enough beer, I may have the courage to try again following your steps...
[Samsung Galaxy S8 Guides, News, & Discussion] jerrygenius:
I am not sure. I am not sure if it can be flashed as well. Because Chinese version is traditionally BL unlocked.... so the BL may not able to flash in at all. I didn't test or try this room. I just post it on if anyone interested in it plz try.
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
So earlier I mentioned that if you get the phone into XAA/VZW/VZW state and you factory reset, it reverts to VZW/VZW/VZW. I followed my steps again on the S8 and it worked; however, I was unable to edit/view APN settings when getting back to XAA/VZW/VZW. I freaked for a bit, reboot the phone and it was still uneditable. A few moments later (like 30-60s), the verizon apn settings populated on the screen and worked. I tested sending an SMS and it was good too.
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
Ok. BTW, did you take the Verizon update from last week before flashing XAC? I did and i'm wondering if that is a factor...
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
I had updated on my 8+ earlier this week, but my SO's S8 was fresh out of the box when I did it a few hours ago.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
you downgraded?? lol i was told at store u have another 14 day window from when you activate the new replacement but i could be wrong
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
Yes, I wanted the pixel density of the S8 for VR. Also, it is easier to text and drive with the smaller S8, lol.

They actually cancelled my original contract, so I have 14 days. I don't want to have to replace the new one, cause everyone knows me there now from spending 4 hours in store while they factory reset it 10 times. I would be embarrassed. lol

---------- Post added at 05:31 AM ---------- Previous post was at 05:05 AM ----------

Trying again using craya's steps. Wish me luck. Craya, which version of odin did you use to flash VZW?
[Samsung Galaxy S8 Guides, News, & Discussion] craya:
I used the one linked to from here: https://xdaforums.com/showpost.php?p=72158471&postcount=433

Also the firmwares were all downloaded from updato
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
when i went i told them i did factory reset so they didnt even try that.. my new one rebooted like 5 times before booting up so they thought the s8s were faulty lol

i also told them all the s8s have the same model # so maybe they sent me one unbranded lol they had no idea what happened haha i played dumb for the most part.. tech over phone was like try this n that but i told vzw guy that wouldnt work so he told the tech guy he wasnt gonna listen to him n e more

in fact, the tech guy over the phone told him to reset network settings at which i originally messed with to get everything but sending sms working and when he reset it it had 0 connection at all lmao so the store rep told the tech guy that when i brought it in only sms was not working then after his steps nothing works so he made it worse haha so he was like were just gonna replace it lmao
[Samsung Galaxy S8 Guides, News, & Discussion] VinylJStar:
Same thing. After they messed with it, I had no signal at all. I've flashed everything and rebooting now. Will report back in a few.

Update: Have CDMA and can send text. Waiting for APN to populate.

Update 2: After reboot, APN populated. Everything is good. Thanks Craya!

For all you having trouble sending mms with cdma phones on XAC, did you try editing the message center # in messaging settings?
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
thats not the issue.. they apparently found the right process but the way we did it before we lost cdma bands entirely
[Samsung Galaxy S8 Guides, News, & Discussion] Quickvic30:
Gotcha. When I flashed the XAC firmware I was watching it flash and it did flash USER DATA of some sort even though the file isn't provided separate like the US firmware. I seen it up in the dialog box when it was flashing.

Also why doesn't mine say the XAC/ATT/ATT? Sorry if this has been asked, I just skimmed through the thread so I may have missed it.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
go lower to software version or something and yes, flashing xac does seem to wipe out ca
