Brazilian guy here

Eu nunca tentei fazer downgrade de ROM's Touchwiz que usavam uma certa versão do Android. Pelo que li aqui no XDA, não é possível fazer downgrade para ROM's que usem certas versões do Bootloader knox por que é uma versão antiga.

Isso só se aplica a ROM's Touchwiz. Por exemplo, se tu tiver rodando o Android 5.0 (Touchwiz) agora, não vai poder fazer downgrade pro Android 4.4.2.

Não há essa restrição em ROM's AOSP, se tu quiser instalar a GPE 4.4, pode instalar sem problema algum.

Espero ter ajudado.

Sorry for comment in Portuguese guys.

Hm, but the stuff that gets in the way of installing older TW ROMs won't also take place when installing third-party ROMs even when they need a different kernel or whatever than what Samsung uses? Do you know what is different?
[Galaxy S 4 i9505 Original Android Development] -Deco-:
Root essentially means that you own the device. Once you root the phone, Knox will trip. Nothing will happen except that your warranty will now be void. Sinply root the phone, remove the Knox bloatware and use Odin (if need be) to flash the TWRP 2.8.7.2 .md5 hash file, from there simply flash the ROM as instructed on the mainpage.
[Galaxy S 4 i9505 Original Android Development] TheOtherTiagoTiago:
Not if you're trapped inside a VM/sandbox; which is what some of the stuff I've read suggests the low level part of Knox does, essentially filtering actions by the OS (and also stuff that happens during flashing), only letting some stuff actually be done, sorta like a firewall for commands.

But like I said, I'm not sure what to believe, been finding lots of conflicting information online.
[Galaxy S 4 i9505 Original Android Development] Strephon Alkhalikoi:
[MENTION=4826477]TheOtherTiagoTiago[/MENTION]: You are correct in that you cannot downgrade from a Knox-enabled bootloader to one without Knox, but that is not the same thing as an encrypted bootloader. Just go to the AT&T and Verizon S4 forums to see what hoops they have to go through in order to get custom ROMs on their devices. Then compare that to what we have here in the international S4 forum.

TL;DR: You're overthinking this. Root, install the ROM, and enjoy your phone.
[Galaxy S 4 i9505 Original Android Development] TheOtherTiagoTiago:
Hm, so what is different when installing a custom ROM from when you're installing an official one that is just too old?
[Galaxy S 4 i9505 Original Android Development] -Deco-:
Samsung wouldn't go as far as to integrate KNOX this deep into the S4. It was never meant as a "safeguard", it was originally aimed at business employees, but it did not succeed. I would recommend that you flash this anyway, it has worked for the rest of us.
[Galaxy S 4 i9505 Original Android Development] Strephon Alkhalikoi:
[MENTION=6958938]-Deco-[/MENTION]: And yet Samsung persists in foisting Knox on every device they sell. ;)

[MENTION=4826477]TheOtherTiagoTiago[/MENTION], as I mentioned in my last post, stop overthinking things. You're getting your head wrapped around conflicting accounts of what Knox can and cannot do, when it will all be rendered moot upon installing a custom ROM. This is because the way Knox works, the bootloader and the Knox apps work together to enforce device security. Custom ROMs do not come with the Knox apps, and therefore the bootloader's Knox code is rendered inert.

[Galaxy S 4 i9505 Original Android Development] TheOtherTiagoTiago:
Hm, alright, so it's not necessary to be able to overwrite the bootloader in order to install custom recoveries, custom kernels, root etc, or is the bootloader in the GT-I9505 actually overwritable even after having installed a Knox enabled stock ROM, and even after tripping Knox? Either way, it sounds like I'm in the clear.

I'll take some time this week to read thru the install instructions of this ROM; but in the meantime I wanna understand what exactly is going on with Knox and custom ROMs with this model in specific.

Hi guys using this versio BT One. And im experiencing a shutdown/dead everytime my phone is idle. Should I flash the BT Two?
[Galaxy S 4 i9505 Original Android Development] corolev:
I tried with the first Bluetooth and did not work me, It turned off the bluetooth like other roms.

I have the second Bluetooth now, and does not shutdown it and I have not found any bug.

The only thing that consumes a lot of battery, but A LOT..I think that has to do with the kernel and has disabled Bluetooth sleep mode.

According explains Alucard,when he finds the solution he published the last and final ROM 5.1.1

First of all, erasing all installed, and installs gapps there in the first post.

Greetings!
[Galaxy S 4 i9505 Original Android Development] Jeffie1970:
Triangle away WILL work to reset the flash counter :) I just did it...Had 15 on my counter...about to upgrade phones, so I thought I would try again to flash the counter. I got a factory ROM from Sammobile, then the old fashioned root "tar". Installed Triangle away, and it actually worked on the first try! I did NOT get the latest build of my SGH-I337m's factory rom. Instead I used a 4.2.2 version...wondering if THAT is why it might have worked. I have tried newer versions with NO luck before.

Maybe it was fluke, but I HAD flashed this phone many times before.

EDIT: Got my Flash up to 5 again playing around, so I tried it again....and the pics are proof that the Samsung S4 IS able to revert to 0.
[Galaxy S 4 i9505 Original Android Development] Schnuerschuh007:
I have the issue 1 too, on version BT_One.

On the version without BT the Bluetooth Service dies after some secounds

I Have now installed the version without BT (20151101) and used the fix from this Post: http://xdaforums.com/showpost.php?p=64022298&postcount=1872

Hi guys,

The day has come, we're dropping support of this ROM. :(

We would like to say a big THANK YOU ♡ to everyone which has been involved in this project, everybody in their little always did something to help us and we really appreciate this a lot.

I'm not writing a farewell post, who said we're leaving?! :)

For now we planned to keep only AOSP 6.0 alive, just some days to get everything set back up and new builds for that ROM will come.

30 November "Final" release includes all the most recent updates from our team and CyanogenMod, you can find it here.

We're sorry if some of the remaining kernel-side bugs (random stuttering audio first) haven't been fixed in our kernel, but as a plan B this time I added a CM kernel to get rid of those bugs. Flashing it will also drop STweaks support (app will be removed too), to get Alucard back just reflash ROM's zip without wiping anything. Download here

A clean installation is highly suggested but not mandatory.

Source code for this ROM is in our GitHub at https://github.com/JDCTeam, I'll update post #2 in a few minutes with build instructions for anyone who wants to build/support it :) you're allowed to release updates in this thread and if you want a post with your changelog just let me know via PM

I wish you all the best.

Mattia

[Galaxy S 4 i9505 Original Android Development] gkai:
Just dirty flashed the final release over the mid October release (with BT patch), everything work nicely, no need for BT patch this time, feels responsive, Bluetooth not crashing (no chance to connect to my car yet), hardware key still buzzing for awhile with screen off is still there, but it looks like a nice final release. Will check battery life and stability in the next few days, this Rom should be nice while waiting for a stable cm13 release (I need theme engine, so I will not go to aosp)

A CM13 port for the S4 will not be built by the JDC team, they are sticking to the AOSP 6.0 ROM which will developed on. 6.0 supports RRO layers, so if anyone is staying on this ROM due to theming, then just know it's possible on the AOSP side. ;)

Since updating the ROM last week to BT-One due to the BlueTooth dropping, everything has been working fine.

Today I tried to flash the updated Nov.30 ROM but it will not let me. I get stuck in the Recovery as the partitions will not mount. I have tried newest TWRP and CWM w/F2FS support since I am using F2FS for my partitions. My guess is that it has something to do with the BT-One img as I can still get out of recovery and boot the phone.

Anyone else have this problem? Any suggestions or solutions?

Thanks in advance.

*** I figured out: You MUST use the unofficial TWRP 2.8.7.2
[Galaxy S 4 i9505 Original Android Development] DSA:
you could look through alucards commit history and see what commits were added/removed...that might give you an idea of whats changed in the kernel to affect the audio

Is anyone else having an issue about the screen waking up automatically then going unresponsive unless you press the power button or the main center button? I remember having this issue a while back on one of the builds.

______________

May have figured this out. lookes like Cyanogen MOd system, Dream Manager service was on. (Daydream was set as a default with Google clock which doesn't appear). I'll give it some time to see if it does this again. (I used wake lock detector to see what may be causing this)

Nope, that wasn't it as I had daydream turned off and it still woke up and froze. Anyone else have ideas? Off body detection?

[Galaxy S 4 i9505 Original Android Development] eisenbergw:
I had this problem while on stock 4.4.2. I flashed this ROM exactly as they said to on the first page, clean build (reformat system, cache, davlik, etc) and after installing this ROM following their instructions, my GPS came back just fine and I haven't had serious trouble with it since. I don't know if the ROM itself is the secret sauce or if it just took the process of a complete wipe to get rid of whatever caused the problem, but that process worked for me.

Did you try doing what is below?
[Galaxy S 4 i9505 Original Android Development] Sebastiansm:
I tried, but I had bluetooth share FC's (couldn't turn on Bluetooth) and Wi-Fi disconnections.

Also, still can't to reproduce sounds.
[Galaxy S 4 i9505 Original Android Development] sagie:
Up until a few hours ago, I had the 20150817 build on my i9505 (jfltexx). The build had its problems, but it was usable as a daily driver, occasionally needing a reboot after a random Bluetooth Share force close.

I finally took the plunge and clean-flashed the final 20151130 build, installed the Aroma package of open GApps and immediately got Bluetooth Share FCs as soon as I was entering my GMail address in the first boot wizard. This prevented me from finishing up the initial setup since the BT FC apparently shuts the Wi-Fi system as well and so I couldn't restore apps etc. (I don't want to use Cellular data).

So, based on what I read in this thread, I tried dirty-flashing the 20151130 build again (followed by re-installation of open GApps with the same settings) - no improvement, I still got BT FCs right at the first setup.

I tried flashing the bluetooth vendor blob (BT_Fix.zip), and got a permissions error during the install, although the file did seem to have been replaced. Anyhow, it didn't help - I got the same problem.

Tried dirty-flashing the 20151113-BT_ONE build with open GApps - same problem.

Finally, I dirty-flashed 20151130 and installed the Cyanogenmod kernel and then open GApps - now it works. At least, I can finish the initial setup and restore apps without any FCs, it's still to be seen how well this holds after some usage.
[Galaxy S 4 i9505 Original Android Development] bswides412:
Did you try flashing the latest build with a different version of the Open Gapps, besides Aroma? I have had luck with the micro package. I too originally received FCs on BT, but a dirty flash of the ROM seemed to fix the issue.

Constant Google Play services has crashed with latest Open gapps (Nano package). Clean install of final ROM.

Also camera is force closing.

Any suggestions?

Edit: using the Delta gapps (base) solves the Google Play services crashing, but the camera force close persists.

I have flashed the ROM and various gapps numerous times, super clean install, and have experienced a variety of bluetooth, Play services and camera crashes, so I would say this version of the ROM is unfortunately far from stable.

Hi ive been trying to install this rom for days using all kinds of methods. I mainly used twrp 2.8.7.2 by antares one.

Ive attached pictures to show the whole installation process. Once i pressed reboot the phone would just stay inthe boot animation forever(40 minutes)
[Galaxy S 4 i9505 Original Android Development] wpyh:
It should work on CM12.1 . I have not tested it on any ROM other than this one (Optimized CM) though. The binary blob I mentioned was taken from a Custom TW ROM (Imperium LL ROM), and it works on Optimized CM, so it should also work on CM.

I would also like to add that, till this day, I have not had one single Bluetooth crash with the binary blob I mentioned. It has been perfectly stable. However, issues like minor audio stuttering when playing music still persists. I don't care about those (music = play), as long as my Bluetooth calls are working perfectly (calls = work) :p
