Hi guys, i am doing this for a friend, hes on offial 5.0.1 LP accidentally updated it and he doesnt like it.
we need to root it and then downgrade Bootloader and Modem then flash a Stock based ROM yes !?
i have fetched latest KK modem/BL from a thread on xda , one with WiFi fix supposedly.. and the latest KK BL as well.
but i cant find a Flashable Stock KitKat Rom anywhere.. can someone help me with this please !?
and maybe link me to the stock Modem/BL as well.. cause i dont wanna brick his phone.
for now i have only Rooted it with AutoRoot.
You don't need to root it in order to be able to downgrade. You might even trip Knox in the process, so you're on the safer side if you don't do that. But as you have probably already done that, you could back EFS up using EFS Professional or terminal, just in case it gets corrupted during flashing.
I'm not completely sure about the downgrade process and what it takes not to brick your I9505, but you can find stock KitKat firmwares (flashable in Odin) here and here. There are some stock KitKat firmwares here as well, but some of them are offline. You can find some firmwares at SamMobile too, but you will probably need to pay to download from there.
Some pre-Lollipop modems can be found here, some more modems and bootloaders here.

hi guys!
i am having samsung s5 g900h, i updated it to lollipop few months back n now i want to downgrade it to kitkat(too much battery drain issue), so i want to know is it safe to downgrade? any problems after downgrading? and what about knox it is 0x0 now will it get affected?
please give me procedure for downgrading and method to root it on kitkat (towelroot will work on kk?)
you should be fine, I updated to lollipop then downgraded back to kitkat easily, you just need to find the file you need for your model and odin that and it should work, for the knox, im not sure about it, but there might be a chance it will be reverted back to 0x0, but you will need to wipe your data in the recovery, or it might not boot at all, and for downgrade/root i use skipsoft android toolbox, it has all the items you would need to downgrade or install root if you want.
Hi.
Question, is there a way to root 5.0 (stock) without tripping knox?
Tried to search\google it, nothing came up.
It's very important to me not to set off knox I still have warranty.
please help :fingers-crossed:
Device model SM-G900F
Nope not really
There was some info about downgrading to KK and rooting with towelroot, then using Mobile ODIN Pro to inject root into a stock Lollipop ROM and upgrade that way, never got that working myself though
No way to directly root stock Android 5 on the Galaxy s5 without tripping knox. However, you can downgrade to a stock 4.4. ROM and then use Towelroot. Afterwards you flash Alexandr's prerooted Lollipop ROM. There are guides everywhere, you could use this one for example https://www.reddit.com/r/galaxys5/comments/2ubsbs/guide_rooted_android_50_for_the_international/

Can I just downgrade to 4.4, root it and leave it like that without upgrade it back to 5.0?
Yes, you can. No one is forcing you to use Lollipop. I find this thread very useful: http://forum.xda-developers.com/galaxy-s5/general/how-to-root-triggering-knox-2nd-method-t2843044
If you just want to use towelroot on 4.4. follow the root instructions and do not flash the Lollipop firmware afterwards.
Hey Everyone!!
Thank you for looking at this thread.
In a nutshell, I got my i9505 galaxy s4 since June 2013, rooted it straight away when i got it, its got twrp recovery, and im on omega v9 4.2.2. Havent touched it since to date
It does not have knox.
Is there a way I can simply upgrade to something like cm 12.1 with 5.1.1 with everything working, by simply flashing latest cm with gapps using twrp, or will I have to upgrade bootloader, radio, get knox, or even just start over, flash stock samsung lollipop firmware with knox using odin, in order to do so?
I already a while back tried updating twrp to latest, and tried flashing cm with lollipop 5.0 when it first first came out, but only 2g was working, and signal would cut if i lock my phone. Im guessing this is due to bootloader/radio incompatibility, or maybe because it was early builds? Apparently i cant flash lollipop bootloader and radio over old 4.2.2 stuff without consequently installing knox? Is knox that bad? I heard its better to not have knox but if its the only thing stopping from lollipop then so be it.
Any help and advice much appreciated.
Hope to hear soon,
DJ
You can try upgrading just the modem to be able to flash an Android 5.x ROM, but it likely will not work and thus you will have to flash an updated bootloader as well. The good news is that since your S4 is out of warranty, whether you trip the Knox flag or not will not matter.
You should be able to flash the updated bootloader and radio without having to install an entire ROM, though you might want to download the latest ROM for your S4 anyway. There is a thread in I9505 General that has a list of bootloaders and modems that can be downloaded and flashed through Odin. From there, you should have no problem flashing the custom ROM of your choice through recovery.
