So, i have s7 G930F which has bootloader version 4. I'm thinking about flashing some custom roms, but i'm not sure if i should flash older bootloader and modem via twrp.. Is this safe via twrp? Will i brick my device? I'll surely brick it if i flash older bootloader via odin, but what happens with twrp? Thanks in advance.

It is very difficult to downgrade the bootloader and methods which worked in the past have been patched. If you don't know what you're doing leave it alone.
And to answer your question no, you can't just flash an old bl in TWRP and expect a rom to just "work". Your better off installing a custom rom with the version of android you want. Then you don't have to mess about with bootloaders.

Hi. Been out the loop for a while and struggling to find the answer to my question.
I'm on 4.4.4 no custom revovery but with root.
I have an OTA notice to go to lollipop, which should be fine, as I have stock evetything?
How do I simply get root back afer the update?
So many posts with options, I'm struggling to find the right answer.
Unlock bootloader, and then either use cf-autoroot or flash latest SuperSU BETA through twrp.

Thanks, bootloader is already unlocked. I don't really want to install any custom recoveries, so the cf-autoroot sounds like the way to go.
Do you have a link for how to use this method?

to use a custom recovery you don't need to flash it.. just boot it.

hi, i really want to downgrade my S6 to lollipop but i have one of the latest bootloader (DPFX).
Downgrade was perfectly possible when i was on first build of marshmallow, but now, since i upgraded to DPFX bootloader, i have only fails with odin, and bootloops with custom roms...
is there any solution? if only i could flash an older bootloader, then i will be saved.
but if i flash an old bootloader with odin, i have a fail, so i don't know what to do
Some people suggested to me to use an old TWRP backup and i found it on my pc (with all partitions files: bootloader,system,radio and data, but i didn't use data) but using it, it's the same of flashing a custom rom: bootloop, and i suspect that the old bootloader never was flashed.

As far as I know if you're on a newer bootloader official or not there is no current method to downgrade. Maybe a phone shop has specialist equipment to do this but that's me taking a shot in the air
I was able to downgrade but not because i wanted, i flashed a corrupt firmware with ODIN and i have to do an emergency recovery with Smart Switch, my carrier doesn't have Marshmallow on the S6 so my phone restored in Lollipop

Good.
What version Android was your phone on before the problem?
Were you on stock (factory) or on custom ROM?
Surely you weren't on Kitkat for almost 3 years?

When you downgrade back to lower stock, you have to omit gpt.bin command. Because you have a newer bootloader.
This is also why you can't take OTA. Because it tries to install a different bootloader (which is probably still older than what you had with custom ROM). If you wanted stock 5.0.2 again, you have to flash full stock image and omit the gpt.bin command.
Are you able to use volume and power button to the bootloader screen?

Before this trouble, were you ever on stock Marshmallow 6.0.1? If so, you can flash back to full firmware of that, but needs to be the very latest. I'll find a link for you.
Also, do you have TWRP installed and did you have a backup you can restore?

Yes before this problem I was in the latest 6.0.1 and the stock I have here when I installed had a security update

OK, then that's the bootloader you were on and will always be on. You need to reflash that latest version (with the security update) to repair. Just reflash the entire full firmware.
There's a link to it here in this forum. I'll find it when I get home, if you don't have it.
Then in the future, if you try to downgrade, you always have to flash full stock version EXCEPT you omit the gpt.bin file. Whether 4.4.4 Kitkat or 5.0.2 Lollipop.
And you can never take OTA.
Because you really have 6.0.1 bootloader.

This is the most likely because all the methods say so old and not one was and when I try to pass any old stock also will not always get that error in the bootloader in the gptbin downgrade logs

You can not flash any older gpt.bin files. You have to omit (leave out) that flash command.
Your gpt.bin file is 6.0.1, and you cannot downgrade. Even on 4.4.4, trying to accept the 5.0.2 OTA update is still older gpt.bin file in that OTA than your 6.0.1.

Hi! I'm really humbly sorry, I'm new to this stuff, so I have to ask you...
I have a Galaxy S8+ Duos (SM-GD955FD). I bricked it once or twice trying to root it. So I had to flash a sammobile.com ROM...
Now this is done, I have a successfully rooted phone with with the Baseband version G955FXU1AQH3 and the irritating "security notice" (since I was not able to install Magisk, and the NotifyClean app doesn't work either).
I would like to flash the latest Oreo and root it. I also heard good things about the Oreo ROM by alexega.
So: I'm on AQH3 rooted. What can I do?
Thank you for your patience.
If wou want to install stock ROM you must follow this instructions: https://forum.xda-developers.com/galaxy-s8+/how-to/guide-how-to-flash-crap-using-odin-t3748555. Bear in mind that if you install stock due to security issues you can't unlock OEM for 7 days after flashing (you must not reboot your phone for 170 hours).
If wou want to flash a custom rom you must have TWRP installed, move the zip rom to your SD card and just flash it from recovery. Make sure to format data before flashing.

Nice, thank you. So I have just flashed the thing with the sammobile.com ROM again (so, no root) and updated to the oroginal firmware Oreo following your link (I worked parallel).
I was just about to root Oreo and was googling for a way... But did I get you right? I should not reboot my phone for 170 hours now?!? So, no rooting until next week?!
Edit: I have developer options enabled and the "OEM unlock" switch is on (it says: "Bootloader is already unlocked.""). So... confusion...

Excuse me, are you currently on Nougat 7.0? If so, you obviously have OEM unlock option available. The problem is in the new 8.0 stock rom, wich sets RMM state to pre-normal preventing you to flash TWRP and to get root in OREO. To skip that you can directly flash a custom rom with 8.0.- Otherwise (stock rom) you must wait 7 days with no phone reboot to get ridd of that pre-normal issue and then flash TWRP and flash Magisk.
Just rooted the new Oreo ROM with TWRP. Works just fine, thank you.
So, what are the advantages of the Oreo ROM by alexega compared to XXU1CRAP?

Do you need a custom rom to not have the RMM lock anymore? A stock with BlackMesa's RMM START .zip is not right?

There's no need to have a custom rom, if you flash the fix in stock RMM lock gets killed everytime.

First you have to install OREO and wait 7 days without reseting your phone. After 170 hours, you get OEM unlock in developer options and you will be able to flasf TWRP. After flashing TWRP you flash RMM-State_Bypass_Mesa and that´s all.

Use Odin to flash the older firmware. Keep in mind that the bootloader may have an anti-rollback to prevent this.

Then you won't be able to flash older firmware unless you flash a custom ROM zip in TWRP.
