LTE+ The Easy Way!

I've been pullin out my hair trying to get LTE+ and root at the same time. I was doing something differently two days ago and couldn't figure out what it was. And then BAM!

If you do the carrier switch and go with unlocked firmware, let's say Att or Tmobile, you at a certain point "Echo" in the sales code for that company... like ATT or TMB. I changed mine to TMB for UNLOCKED Tmobile, but TMB is ALSO the code for LOCKED Tmobile. Basically when I would reset for SamFail, the system was seeing a US based phone, asking for a TMB setup, so I got LOCKED TMB.

All I had to do after SamFail install was go through the phone setup process, install Terminal Emulator, run TE, type SU for Super User (You have to grant it Su access, and if the SU command works the $ symbol in TE will become a #)

Then type the follwing:

echo "XAA" > /efs/imei/mps_code.dat

That changes the sales code to US unlocked. Then reboot into recovery, do a factory reset, and when your phone boots it will probably show H for signal. After setup if it isn't LTE or LTE plus just toggle Airplane mode on and off and Voila! You should be now able to get LTE/LTE+ !!!

Hopefully this can save people some headaches and provide faster internet to the masses!

(I had max download speed on speed test 103mbps)

Hi. Can you confirm if after flashing from vzw to non carrier sw you're able to gain access to samsung caller ID and spam blocking features?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jdoggz:
Yes, both of those features work.
[Samsung Galaxy Note 8 Guides, News, & Discussion] spaceghost21:
Ok so I followed the switching carrier and also the flash carrier firmware guide on my sprint branded note 8 to switch to ATT firmware with bloat to get its features. Everything went smooth, the wifi-calling toggle appared in my notifications drawer but when trying to activate i get an error (EDS 0008). I did call att and had my imei provisioned they said they were pushing an update ota to get features working since i had mentioned i bought it from "samsung". I am on AQIA firmware with no problems with regular calling and text(not sure if video calling works but the button is on my dial pad). How can i fix this wifi calling issue?
[Samsung Galaxy Note 8 Guides, News, & Discussion] arrrstin:
I wish I could confirm it to that specific degree. I can only confirm that is it working with my AT&T Note 8 cellphone. I re-flashed back to stock (uncompromised) rom and everything works including OTA updates and samsung pay.

Is anyone going to stick to 950u1 odin builds and ignore otas? The carriers push out branded unlocked firmware. And the carriers will restrict certain modules or lock down the OS. Is that correct?

SPR -> TMO

I'm going from Sprint to TMobile but after updating through ODIN the phone reboots and tries to update Android but only makes it to 32% before stopping and cancelling the update.

Any ideas?
[Samsung Galaxy Note 8 Guides, News, & Discussion] jmdomini:
So went ahead and flashed my Sprint Note with the unlocked firmware. Much appreciate the lack of bloat! Thank you BlueFox for the instructions!

One question for those of you on Sprint. As you probably discovered, not only does Sprint's visual voicemail app not work on the unlocked flash; but you will also cease to receive any notifications at all for carrier voicemail.

OK fine, I setup a Google Voice number as suggested and setup conditional call forwarding to that number. Trouble is it rings about a dozen times before voicemail picks up. I set "When someone calls this phone directly and I don't pick up" to "Go straight to voicemail" in the Google Voice control panel. However this setting seems not to have any effect. I'm guessing the OCN isn't getting passed so GV doesn't honor the "go straight to voicemail".

Am I missing something stupid, or is this just the way it works?

im on N950USQS2BQL9 sprint. I want to stay on sprint but flash the unlocked version for less bloatware but I think now that im on an updated bootloader I cant... Right?? or am I not looking at download files right ?
[Samsung Galaxy Note 8 Guides, News, & Discussion] _Dennis_:
You're on bootloader 2, so it's all good. There are bootloader 1 and 2 files.

Going backwards from the software number yours means:

9: version 9

L: month released (A=Jan)

Q: year (2017)

B: Android version (7.1.1)

2: bootloader version (number 2)

Hello. If I'm on verizon and would like to go to unbranded sw, what's the best way to back up phone settings, apps, messages? Vzw blocked the Samsung Cloud. Can I use the Smart Switch?
[Samsung Galaxy Note 8 Guides, News, & Discussion] woodyjlw:
thanks! I guess where im still confused is where mine is the 950US and the others are 950U1. I am looking at this one (XAS) Sprint Non-Branded - N950U1UEU1AQH9/AQI5/BQK1/BQL2 as the one I need so the question is dose flashing to unlocked firmware change my firmware numbers from what the factory sprint ones im use to seeing? and I know that this dose not unlock me to use other carriers unless I pay or get sprint to unlock but since im staying with sprint this is just to get less bloatware. do the apn settings set up auto with a sprint sim card already in? thanks!
[Samsung Galaxy Note 8 Guides, News, & Discussion] unloop:
My apologies, I am sure this has been asked in on of the first 90 pages.

I am still on a Note 3, I haven't done any custom phone stuff in a while. From what I've gathered here, if I purchase a 2nd hand T-Mobile Note 8, I can then flash a "carrier free" version of the firmware, correct? I use Straight Talk and really hate the bloatware. If I do this, will there be any issues with getting firmware updates straight on the phone, like the incoming Oreo update? I don't want to root right away (maybe after Oreo if possible).

Why you say Verizon blocked Samsung cloud?

I think Samsung cloud is working!

Do you have any error when you try to use Samsung cloud?

I'm not saying your are wrong, mine has Samsung cloud working. But mine is unlocked one, not Verizon brand. I don't know is there is any difference.
[Samsung Galaxy Note 8 Guides, News, & Discussion] yanik73:
Unfortunately, there's a difference between our phones. Mine is loaded with Verizon sw and features like Samsung cloud, caller ID and spam protection are blocked.

I used phone all day today with no difference on service or speeds and I like not seeing the sprint startup screen too :) OH and now I am able to use samsung caller id that sprint blocked on stock.

Flashing U1 From ATT Carrier BLQ5 to Verizon Carrier BLQ5

Hi all,

I recently flashed my U1 to the AT&T BLQ5 Firmware to see if I could go through the AT&T Office of the President to get them to whitelist my phone's IMEI from the top of their foodchain. Unfortunately, the representative declined and simply told me at this time it is not officially their policy to allow non-branded devices outside of a few outdated iphone models this courtesy. She is, however, making an official report on her end of the inconvenience and forwarding an official request to top brass to request a policy change (whatever the hell that's worth lol). Anyway, I'm trying to flash my direct from Samsung U1, which as of right now has complete ATT SM-N950U BLQ5 firmware on it, to the Verizon version of the BLQ5 firmware to try my luck with getting WiFi Calling enabled on their network.

I tried going into download mode and flashing the Verizon carrier software over the ATT version using standard Odin (following the instructions under "Flashing Carrier Firmware" (in OP), but every time the device PASSED and rebooted, it booted with the ATT firmware and not the Verizon version which had just been flashed. I then attempted to restore to XAA Unlocked BLQ2 with Prince Comsey Odin, and it PASSED and appeared that it was successful. It booted without any sign of the ATT bloatware being on the device. So, then I figured I'd just follow the same process laid out in the OP I'd used to flash the ATT firmware originally with standard Odin "Flashing Carrier Firmware" (in OP), which I again executed successfully with the Verizon firmware, but when the device rebooted after PASSING the flash, it AGAIN rebooted with the ATT bloatware! No sign at all of the Verizon firmware which I had flashed to it.

I assure you no stupid mistakes have been made here: ie. I did not flash the ATT firmware again by mistake. I have double-checked all the files each time before flashing. Any idea what's going wrong?

How would one enable enhanced/advanced messages with stock messaging app? I believe it is RCS. I have enabled it through shortcut light but it doesn't work unless i use Google Messenger. I am running the unlocked software for sprint.

Edit: NVM BlueFox stated it wasn't available for the unlocked note 8 on Sprint. I can get it working through Google Messenger, but I'd rather use the stock app due to I can theme it black. Google, can't be done from what I gathered. I'm not rooted and don't plan to. If someone has figured it out please share. Until then, I shall keep on trucking the way I have been.

:confused:

L☆ and K☆ :cyclops:
[Samsung Galaxy Note 8 Guides, News, & Discussion] OptimuSlime:
Like tmobile software might end in L5 or LA... you can flash a lower letter (like ending in K2 or K3) firmware. You can flash ANY US CARRIERS FIRMWARE and as long as it has the same bootloader revision number (1 or 2 currently) you can downgrade. Then you can use the guide. It's like the first thing written in the guide. There is a K2(3?) Factory binary but not a LA, L5 or any L*

So you could flash a Verizon firmware, it will see that you don't have a Verizon phone, and will boot as tmobile or whatever carrier you have

You would download a supported firmware, load it into Odin, flash it, then use the guide on your new lower firmware:D
[Samsung Galaxy Note 8 Guides, News, & Discussion] unloop:
Sorry, I now understand part of what I am reading on the 1st thread:

"For use withBQL1/2/5/A Firmwares

N950USQU1AQL1_COMBINATION - Uploading when I get it...try downgrading firmware and use the previous version until uploaded

HOME_CSC_OYV_N950WVLS2BQL? - Uploading when released..."

Is there a thread here on XDA or anywhere that would show steps to downgrade firmware? Do I just download the BQJA version of T-Mobile first, use odin to flash, and then do a carrier switch?

I want to ultimately put the XAA Unlocked version on it. If I ever get there, would I benefit from putting the ATT carrier XAA version on it, since my Straight Talk account uses the ATT towers?
[Samsung Galaxy Note 8 Guides, News, & Discussion] OptimuSlime:
Yes the BQJA is perfect. Yeah just flash it onto your phone (after saving files from it... they get wiped) using Odin. Then use the guide. I got caught up on that part myself when I read the guide, since I was on LA firmware. I read that you couldn't downgrade, but it's just below certain firmware, and can't downgrade below the revision number. LA firmware is U2 so anything with a U1 in that place won't flash. Like you couldn't use tmobile N950USQU1AQ** ... because of the 1 where you currently have a 2.
[Samsung Galaxy Note 8 Guides, News, & Discussion] unloop:
Thanks, I think I have a better understanding.

Step 1 - Flash BQJA from Tmobile (1st post here) using ODINn to replace the BQLA that is on it now.

Step 2 - Follow the guide, starting with the carrier switching since I am going from T-Mobile to No Carrier (unlocked)
[Samsung Galaxy Note 8 Guides, News, & Discussion] stealthyp:
Clarification Needed...

Does this mean those who flash BLQ5 will not be able to switch carriers or lateral flash until these files are posted? I tried to use the most recent files posted below this entry and it didn't work :eek:​
[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
Downgrade to switch carriers and make sure to change CSC to intended carrier
[Samsung Galaxy Note 8 Guides, News, & Discussion] stealthyp:
So you mean flash an earlier AT&T firmware version to overwrite the BLQ5 like the AT&T BLK2 or BQjA using the "Flashing Carrier Firmware: Steps in Post 3" just like I did to flash the BLQ5 firmware originally?

and this means to basically follow the instructions in the second post for "switching carriers" before heading to the third post about flashing another carrier's firmware?

Please pardon me to trying to be very precise about your instructions, but I'm a little 'gun shy' at the moment: I began to be fairly positive after attempting to follow the instructions in the Second post (by applying the BLK combination file [because it was the 'latest available'] over my BLQ5 installation) that I had flung ~$1000 out the window carelessly, and I'm generally not a careless person lol.. The phone would not go into download mode and was asking to be connected to Smart Switch on PC for an emergency restoration, and when connected to the PC, the PC Smart Switch didn't recognize it as a device that could be restored. Needless to say, a few years of my life were left behind there until I managed somehow to get it to restart, and it was like nothing had happened at all... except to me, of course lol.

Thank you for your help!!!
[Samsung Galaxy Note 8 Guides, News, & Discussion] OptimuSlime:
I tore into my Note 8 on day 1, and have been pretty careless with it flashing wise. Almost anything can be fixed through download mode, using Odin.

Even if the screen looks the color of download mode but has a warning, you just flash stock or Samfail with Odin and Shazam! Back to good.

Ignore smart switch or other software, just use Odin. If the phone seems unresponsive, try holding power and volume down. Usually it's just slow to restart itself, hasn't powered all the way down yet and we try turning it back on.

If you get upload mode or kernel panic just hold volume down and bixby (No Power) and download mode will come on without a hitch.

If download mode is stuck, or bad flash, or cable came out or pc died midflash or whatever, just hold Vol Down and Bixby and Power. Download mode will start fresh and you can flash again.

Samsung has made this phone really hard to get into, but also really hard to permanently brick.

I have used this guide probably 20 times on this phone (didn't realize I could do half of it changing csc with root lmao) and the guide works.

Happy Flashing!

Just found this nice bit of info... says it gets video calling working on Unlocked firmwares. Can we use Shortcuts to enable Wifi calling also?

If so...then XAA would be just like TMB except for the extra 2 bands XAA can access (band 252 and 255 I believe) that are recently active in cities like... Las Vegas!!!

[MENTION=5649240]BlueFox721[/MENTION],

Just FYI, it appears with the new Blv3 firmwares, the device will only accept official firmware. Meaning, no more flashing U1 firmware on the carrier models, or vice versa. No more flashing U or U1 firmware to the Canadian W models. Flashing between carrier firmwares is fine as long as it's on a carrier branded device (running TMB on a VZW device, etc). But running 950U firmware on a 950U1 will result in a brick, that is this far unrecoverable.

If your currently are running U1 firmware on a U device, vice versa, or running W firmware on a U or U1 device, or vice versa, you need to flash back to the firmware version that shipped with your device BEFORE you accept any OTAs that take you up to Blv3. That would include all the January updates.

This has been tested and confirmed.

[Samsung Galaxy Note 8 Guides, News, & Discussion] BlueFox721:
BQL2 is the unlocked firmware...the carrier USERDATA files are in the carrier stock firmware...

Although you could try using the switching carrier guide to change your CSC code to XAA and then flash the BQL2 unlocked firmware...we have found out that the carrier CSC code will block settings on the unlocked firmware and that the XAA code will give them back...the SIM will direct the install to ATT so you will still be ATT but may have access to all XAA settings...

If not, use the ATT stock CSC file before using the USERDATA file...
[Samsung Galaxy Note 8 Guides, News, & Discussion] nelms:
I was under the impression that I was already on XAA BQL2 firmware due to being a factory unbranded note 8. N950U1. I was just gonna pull the csc and userdata from the correct att firmware to hopefully activate the ATT specific features. Which att firmware should I get these files from ? I am worried about mixing things I shouldn't and messing things up.
