CP/BL question - Samsung Galaxy S7 Edge Questions and Answers

hi guys,
When flashing a new stock rom on the device is it really needed to have the latest bootloader and modem flashed ?
i mean are there any benefits over the previous one ?
thank u

BenjaminW8 said:
Yeah because when you have lets say apf2
And your still on bootloader and modem from
Apd1bl
Then you know its not quite a match
Plus you boot quicker if your on the latests base with same BL and CP
Makes dirty flashing also better

ok thank you.
for example see these two official roms:
http://www.sammobile.com/firmwares/download/75144/G935FXXU1APF3_G935FVFG1APF3_CYV/
http://www.sammobile.com/firmwares/download/73520/G935FXXU1APF2_G935FPHN1APE2_PHN/
same changelist number, more or less same date released.
which CP and BL should i have ?

[TEST] MM for T715Y

I've extracted the bootloader and modem form the T715 firmware and made them Odin flashable.
Still haven't tested it but It should work on the T715Y
I've also made this Rom with android Kitchen so you'll need a custom recovery to flash it.
So the steps are simple
1. Flash sboot.tar.md5 through Odin on the BL tab
I believe you don't really need the modem
2. Flash the tab2.zip through a custom recovery.
Again I haven't tested this so I don't know if it works

is it an "RQT_CLOSE" error?
that seems to be a security error, it prevents odin from flashing firmware that is not 'original' to the device.
Damn you Samsung!
I guess we'll have to wait for a bootloader meant for the T715Y

Hi, first let me thank you for giving this a go in coming up with work around to get MM with variant T15Y which seems to be totally forgotten by Samsung as its still rocking LL v5. 02
As much as I want to give this a try my concern is tripping the Knox, flashing through twrp, which from my experience with my Note 5 has lasting effect with high battery drain after upgrading to MM. As far as I know there is no way of reverting knox to 0.
On the Note 5 forum, the N920I variant is the last to be upgraded to MM. Someone has come up with work around using the variant N920G (I believe its the India version) by unpacking the rom into 4 files corresponding the BL, AP, CSC, (i can't remember the 4th one) then repacking if into tar files to flash using ODIN. I have initially upgraded my N5 using this method and worked perfectly without tripping Knox. This method only works between the variants N920I and N920G, my understanding is that because they are almost identical versions. I wondered if this this is also the same scenario with the tab s2 T715 and T15Y, if so I was wondering if you or anyone on this forum knows or better yet can give this method a try. I don't have any experience with rom development but happy to give this a go if pointed to right direction. Ihope we can keep this T15Y thread going. Cheers

The 4 files are simply the factory images downloaded via ota. Same as is in the all in one tar package downloaded from somewhere like sammobile. The problem with the Y version is that for some reason it is picky about its bootloader and will only accept a particular one.
Its probably a waste of time trying to flash any other bootloader until the official one is released.

Sad to know.., although I don't really have any issue with my tab as I mainly use it for browsing and as e reader, but as everyone here would agree its reassuring to know that your your device is currently supported by its manufacturer and the option to upgrade is available. Cheers
So, it doesn't work?

Yes, you can downgrade APG1 to APD8!!!!!

First, flash ENG boot in the AP. Then, go back immediately and flash the CSC CP and AP of the ROM of your choice. Simple, easy, DOWNGRADE COMPLETE!!!

when some one tests this can they please do a video to prove if it works, also can we flash CSC that does not factory wipe the phone. also I don't remember for sure but isn't the U firmware bootloader 2 the international version with the unlocked bootloader?
I wanted to know you you could wip up a quick tutorial or steps for us . I can tell its really simple and easy. but once we unzip the firmware wont it then lose the md5 has and signature. of are the 5 files inside also signed.

Yep, if this works then the OP is a genius who's name will live on in the T-Mobile s7 edge forum. People will be able to flash the U firmware again. Can someone also verify that knox doesn't get tripped?

Since they are all official and signed files I would assume that this would not trip knox. But I can not verify for sure. Also I thought knox checks to see if the boot loader is unlocked.
I have another question. with an unlocked boot loader don't we still have the problem of dm-verity being enabled that would stop use form flashing mods and roms.

The main thing that *most* people want is the U firmware. Also, I'm not really sure exactly what knox does other than to not trip it.

If this works, this would be amazing. I don't want root, I don't want to even unlock my bootloader, I just want to put the U firmware on my T-Mobile S7.
Not to get off topic but what's the big deal about the u firmware is it Universal or is it unbranded with a lot less bloat. Or additional features?

It is unbranded, let's you uninstall bloat apps completely, and unlocks most us bands.

"Yes, you can downgrade APG1 to APD8!!!!!" pd8 i guess is bootloader v3. if he downgrade to bp8,this thread thread will be on fire!!!
I'm pretty sure pd8 is v3 bootloader also. Shouldn't be any issues downgrading pg1 to pd8 regularly, both same version bl.

I'll be happy to try on the next couple days, but I'm having a hard time finding a good link to the U firmware that doesn't require payment. Anyone have a link?

It is not bad, but comes with a later bootloader which can limit some options.

Android Nougat for G935FD (Australia)

Hi there, just wondering does any Australian users who own G935FD flashed the Nougat beta firmware? Does it perfectly work with any carriers? And will I still receive OTA afterwards? Cuz I really want to try the new rom but couldn't find any official stock as backup. Many thanks

1) Yes
2) Yes
3) No
4) Official firmwares - flash via Odin. http://www.sammobile.com/firmwares/
I'm on Nougat Beta 1 flashed via odin. Definitely recommend.
Next time, please read the forum title before posting. As you can see this forum is for news&discussion NOT q&a.
I am an Australia user who flashed Nougat beta 1 as soon as it came out. Haven't had any real problem with it. It has minor bugs here and there but its good enough for my daily driver.

No I flashed a generic XSA CSC from the latest Marshmallow official firmware. Download and extract from the zip on Sammobile. This was an attempt to get Samsung Pay working, but it looks like they're disabled it for Nougat regardless of the CSC.

Thanks for remain, one thing I am still concerning that when I flash back to official stock, will I still get OTA? Since my Galaxy note4 is running on an official stock and still can receive OTA after I flashed many times of different ROMs.

EPK2 bootloader and modem for N910T

I downloaded the EPK2 firmware from sammobile and parted out the BL and CP for those of us on custom ROMS. This allows you to ODIN just the BL and CP w/o losing yer custom rom or any data or anything. Tested it myself and am currently running it trouble free.

I've been on FireKat for a long time which uses 4.4.4. I'm a little rusty on this but can I update my bootloader and modem now with this one and still use FireKat on 4.4.4 until I find a newer rom on 6, 7 etc I like later? Was thinking yes but wanted confirmation first or reasons not to.
Thank You kindly for any info!

This may sound stupid to some, forgive my ignorance, but if I flash the BL and Modem over my current DOK2, can I then just download and install a custom rom that is based on EPK2 and flash it like normal? Or do I need to actually flash the OFW?

You will have to flash a newer ROM. Whatever DOK2 ROM you are using now will prob not play nice with the updated (not upgraded) BL and baseband. Personally, I haven't found a MM ROM that I liked for this device.

Yeah that is what I had planned on doing. I was just wondering if flashing just the modem and BL would allow me to then flash a custom MM rom without having to first flash the full firmware. Was just looking for a short cut. But I have not decided if I want to upgrade or not. I am currently using Maximum Overdrive v7.1.1, just seems a bit sluggish these days.

Help me identify the correct FW to flash/update to Pie 9.0

I have an Sprint Samsung S8. I want to update to Android Pie 9. Its currently on Android 8.0.0 - R16NW.G950USQU5CSA4. And I want to flash with Odin to any compatible Android Pie FW. I am personally not looking to unlock or anything. The confusing part is that when I research the FW version (G950USQU5CSA4) it comes as a Verizon FW. So I am not sure if is safe to flash any of the Pie FW available on sammobile for Sprint.
It is safe to flash for example to one like G950USQU5DSD3 that appears in Sammobile and is for Sprint?

For any newbie like me who ever had a look at this thread. This definitely work as said by @kpwnApps, I downloaded SM-G950U, build G950USQU5DSD3 (3.92GB) from Sammobile and flashed with Odin. Flashed AP, BL, CP, CSC (not CSC_HOME) on its respective place on Odin. 5m 32s later it was updated with no trouble.

Last question, I am personally not interested. Just curious. As long as is the same android version, would it be possible to downgrade too by flashing with Odin and earlier version? or would something like that cause a brick?
