Hi,
I have experience with the Canadian S4 I337M, currently running custom Validus ROM 5.1.1, originally was on TouchWiz 4.4.2;
I have altough a question that seems quite.. debated, did looked around I can't find a definitive answer and know who I should trust. I wonder if options changed in 2015 rather than 2013 when KNOX was still new.
Out of simple curiosity (I will not attempt it, risky, probably useless and I'm running 5.1.1 anyway): I keep reading that it's impossible to downgrade the S4 to 4.2.2, due to the KNOX bootloader on 4.3 / 4.4, I understand that you cannot downgrade below 4.3 which is the "new" KNOX bootloader.
1. I'm simply curious: On the I337M, what happens if you grab the stock 4.2.2 firmware and flash it with Odin anyway, considering I'm on 4.4 ? My guess, if I'm correct, Odin detect the bootloader version right away and says "FAIL". Correct?
2. I used to think it was possible to downgrade from 4.4 to 4.3, since 4.3 has the KNOX bootloader as well. Is this possible anyway, or will Odin fail (Not going to try it, not worth it)? Considering what I've read just today, 4.4 is also a new bootloader. In any case, since that 4.4 bootloader cannot be downgraded (I guess?), there is no way to downgrade from 4.4 to stock 4.3 either? Odin will show "FAIL" ?
3. Is there any other way to downgrade it anyway? I understand that KNOX 0x1 remain irreversible yet, and to my knowledge, it's impossible to dowgrade to 4.2.2 (Or even 4.3?), but I've been reading that it was possible to downgrade if the bootloader is excluded from the TAR archive, make sense to me, but is that true, was that patched? Should I recompile an ODIN package excluding the bootloader, is that how it's done (Too dangerous, not trying it)? Or maybe by using Mobile Odin / FlashFire, downgrading from 4.4 to 4.3 / 4.2 can be acheived, if the bootloader is left untouched? What happens if we try it anyways? Odin fail, or device does boot but doesn't get past Samsung boot logo?
I'm just wondering, and quite confused by the different opinions that were shared. Remember this is for the Canadian I337M variant.
Thanks for confirming, appreciate!
Hey there I just got a new samsung galaxy s5, and I have been searching on the internet since yesterday, and haven't been able to find a thread that gives me information about installing custom recovery or installing a rom based in stock without any bloatware.
My phone is the samsung galaxy s5 sm-g900v (not rooted, i haven't been able to do it, maybe it's not posible yet )
android 6.0.1
kernel version 3.4.0
So my questions are:
Can I flash the twrp.tar file with odin?
Is there anyway to install a rom based in the stock of samsung but without bloatware?
And finally, can I root android 6.0.1 in my verizon s5?
Thanks in advance
you have alot to learn my friend.. if you are on 6.0.1 i dont think you can downgrade. you need to be on a 5.0 and then root then if you have a samsung board you can unlock the boot loader to install TWRP if its a toshiba you cant..

I just got the s5, but i get rid of it,im back on my old lg g2, seems it was imposible to install a clean rom on that device.
6.0.1 is downgradable. If you had a 15 chip then you could get TWRP. Even if you had an 11 chip you could still flash a debloated rom on Lolipop.

I've searched but I'm lost on where and how to downgrade 6.01? Is it just flashing over a 5.0 ? or is there more to it because it's new? And where can you find a guide for rooting 6.01 or downgrading it and then rooting?

I already gave the phone to my gf, but what would happen if I try to flash a stock based debloated rom with my pc? I mean flashing the debloated version of 6.0.1?

Flash a G900V 5.0 Lollipop Odin TAR. If you have a CID 11 chip then you can either:
- Downgrade to lollipop and stay rooted their.
- Stay / upgrade to marshmallow but not have root.

you can downgrade from marshmellow to lolipop however you cannot downgrade to kitkat due to the fact that the bootloader is different
I advise you DO NOT make move to unlock bootloader on locked device.Like install 900f roms 900f kernels. Because i tried this **** and my s5 is turned to trash. Do not try belive me.

Why are you advising those with a locked bootloader not to unlock it? If you have the right emmc, there are like 4 different methods to do it. It's simple!
I have a Verizion S5. This means that long process of downgrading and unlocking. So, I followed the steps, downgraded, rooted, and then unlocked the bootloader. I had the most recent TWRP and then installed Cyanogen based on 6.0.1. Everything is working fine but I'm just curious as to the process.
My question is, how is it possible that Cyanogen (based on 6.0.1) installed on Android 5.0?
The other question I have is more technical. But I'm confused on what I did to my phone with all of the flashing kernels etc. when I was unlocking the bootloader. Was it that a program changed some setting in the phone to change it to a Developer model?
Thanks to anyone that can help me out on this.
Hi, is this even possible on an ASUS_T00P running Lollipop WW_12.4.5.58 ? I've seen threads where you need to downgrade it to Kitkat first before you can unload the bootloader and then root it. Was wondering if it was possible doing it straight from Lollipop. All the other threads which say you can do this seem to mention a different version of firmware on the phone. Thanks.
Hi guys, i absolutely need to downgrade my Oreo 8.0 to Marshmallow 6.0, but i cant simply flash it with Odin becouse of that damn bootloader, there's a way to downgrade the bootloader?
As far as I know, the bootloader cannot be downgraded. Sad truth, I ran into the same issue with my s6 edge + and lollipop.
