New S7E, want to flash U firmware. How to go about it? - T-Mobile Samsung Galaxy S7 Edge Questions & Answer

I have a new S7E that's on the May 1st Security Patch (baseband version G935TUVS3APD8) and was hoping I could flash the U firmware. Is this possible? How do I do it?

I'm pretty sure you won't be able to because your already onpd8 and have bootloader v3. The U firmware needs bootloader v2

Unsure about updates.

Hey guys i have question. I am currently on 24.11.18.lux.reteu.reteu.en.En reteu. I flashed this with a link that was posted on here before the update for 6.0 came to my country. The update that came OTA was 24.41.33 (with the januari patch). I never received this and am wondering if i will still get updates in the future or if I have to keep doing this myself. I am not rooted or anything. I just updated with the link that was posted here. http://forum.xda-developers.com/moto-x-play/help/marshmallow-ota-uk-t3277756/post64971862#post64971862
So basically:
I flashed from 5.1.1 to 6.0 myself with link posted here through recovery mode.
I now have 24.11.18. (december patch)
Others in my country that just waited have 24.41.33. (januari patch)
What do I do now in order to get updates? Wait and it will come? Or do i have to keep updating myself?
Hope everything is clear. :good: Thanks in advance.

The best to do is flash the 5.1.1 factory image for your model and location. And then updating through the normal way. Not manually
Thanks. I'm not sure how to go about doing that. So updates wont come to my phone anymore OTA? I've read on here that the 6.0.1 update should arrive soon. I'm new to all this and don't want to risk breaking my phone. Maybe it's better to wait? I'm from the Netherlands too btw.

You should have the january security patch, if you dont and dont have an update you need to flash the factory image. If you don't want to brick your phone you shouldnt flash updates manually in the first place.
You can also try this: https://www.androidfilehost.com/?fid=24421527759884307 which is the flashable zip for the dutch 6.0 firmware (but you need twrp and unlocked bootloader for that.
But you probably need to download and flash this: https://www.google.com/url?q=https:...sntz=1&usg=AFQjCNGTQx60cH6emtbDNwtOZh-3m7Mdww
And follow this: http://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750
(doesn't need an unlocked bootoader
Thanks. I think I'll just wait until 6.0.1 arrives here in NL and see if it let's me update too before i try and do all this.

Flashing U Firmware

Hi,
I was wondering if there is a way to go from the P Sprint firmware to U firmware. I want to be able to root my device on QL1. The guide on the forum is for U firmware, but I attempted with my stock Sprint firmware and the only thing I couldn't get to work was mobile data, as APN settings are not adjustable on stock firmware. Is there a way to flash U firmware if I am on stock P?
Thanks,
csmyka

It is possible if your bootloader version is lower than 5, firmware for unlocked version have latest bootloader revision 4. Sprint updates bootloader just to remove this possibility of crossflashing. You are on QL1 version so is not possible at the moment

I have upgraded to RA1 since I posted. Does this still make it impossible?

RA1 is still on 4. If you look at past firmware info, this should be sorted out when Oreo drops.

I believe i read somewhere on here that you can only flash the same bootloader version as 8.0 is version 2 so the only one you can downgrade to is one with bootloader version 2 and that is 7.0 i understand. Correct me if i am wrong though,

Correct.
Find 7.0 Firmware that is at least March 2018 or newer (Binary 2 Rom) to downgrade from 8.0 Oreo

Just download the firmware for 6.0.1 and flash it in odin, I've done it several times and it works very nicely.
I'm surprised they would allow 6.0.1 firmware to flash what model is your phone sm-g935f and was it on 8.0?
BL code drops to 6.0 without code but network goes

Hello,
I downgraded to 6.0 but phone is now stuck in boot loop and i'm unable to access recovery mode.
I'm only able to access download mode.
Please how can i resolve this problem?
Hey guys, who knows do we have option like — flash fw with older bootloaders and then do isolated new bootloader flash to make older fw work?
Something like that, because i "heard" similar tricks in internet, like people are flashing modem and bootloader bins separately after downgrade flashing like from android 8 to 6. But didn't find proper instructions on that.
Is it possible? Is there instruction out there?
Yeah, oreo is better than nougat and yeah yeah new features, new updates blablabla. I just believe that every device is always better with its first software - we all saw and know how Apple does, i dont think that other companies dont do something like this...after masscopy of notches personally i dont have any doubts...why you think samsung "upgrades" this bootloader sh*t? It's the same thing like it was with iphone 4s - no downgrade option, and "upgraded" version of fw forcedly reduced the work of processor and other performances - you forced to BUY new one. Same politics in Samsung.
Well, for me marshmallow is better than all others in using S7 - it's faster and bugfree than nougat or oreo, yes it's oldy and even some basic performance features not exist, but still android 6 is the best for S7. I used custom roms but they are really buggy, badly buggy, definitely not a choice for everyday using. Oh i missed the days with nexus phones...not pixels.

Downgrade Samsung Galaxy S7 EDGE

Hello guys! I would like to downgrade my Samsung Galaxy S7 Edge to a version where I have the outdated security patch, preferably in the May 2018 version for me to play Pokémon Go. However, I downloaded a ROM of that date but when it was installed, the security patch remained the same, February 2019. I am downloading another ROM, but with the android version 7.0, but if anyone can help me in knowing what the problem is, thank you!

Possible to downgrade to stock Android PiE with older security patch?

I have an unlocked Samsung Galaxy S8 (G950F) on stock ROM, Android Pie, on security patch June 2019. Is it possible to downgrade it to stock ROM, Android Pie security patch March 2019 using the Odin method? I have already downloaded the appropriate firmware (G950FXXS4DSC2).
No u can't downgrade anymore , your bootloader is on v5 and there is no way currently to downgrade bootloader to older version
Thank you for your response. Theoretically would I be able to downgrade an S8 on the May 2019 update (G950FXXU4DSE4) to the March 2019 update (G950FXXS4DSC2)? If I am correct the digit after FXXU, i.e 4 represents the bootloader version, which is 4 in this case.

Yes u can downgrade to any earlier pie or Oreo frimware as long u didn't install June update
I thought this was possible too. That's half the reason I rooted. A security update messed up my night mode and it's very annoying. Shame. I doubt Samsung will fix it with any future updates.
