[Q] official 4.3 downgrade to official 4.1.2 - possible?

Hi, I've searched the forums here for a while but have honestly not found the answer so I hope someone can help. I have an S III I9305 which I updated OTA to the official 4.3 last week. the baseband version is I9305XXUEMK1 and the kernel version is dated Thursday 12th December. From searching I've only found the baseband I9305XXUEMKC which I believe was dated around end of November 13.
I simply wanted to know if there is any way to go back to the official 4.1.2 (i.e. as it was before the update to 4.3). I have not rooted the phone or done anything else with my phone. I have read all the stuff about Knox which I believe could prevent the phone to be downgraded without voiding the warranty, but this is not really a big issue for me as I've had the phone for over a year now. I was not ever planning on rooting the phone or adding any custom roms either. Just looking for a way to restore the phone as it was really!!
Hope anyone can help, and advance apologies for what is probably a very nooob question.
thanks

The 4.3 bootloader (Knox) does not allow any downgrade irrespective of Knox flag status. This is an issue many users are not happy with.
Sorry.

thank you for replying to me, this is thoroughly annoying and I am gutted that I didn't see the problems people have described before updating! Just assumed that an update would be an upgrade!! clearly not. Is there anything else that I could do to make this bad situation slightly better? or have a made a rod for my own back?
appreciate you taking the time to reply.

Standard reply .
Factory reset .
Or flash a stock or custom rom .

There is nothing you can do for now except to wait and see what developers come up with. I would advice not to update to 4.4 kitkat yet unless you are sure you want to do so. There is no way back from 4.4 to 4.3 either.

i wasn't aware that 'no way back' can be fractioned into bits haha
please stay polite with your goys fellows, they can insult you as well

thank you all for taking the time to reply.
I think i am going to stick as I am for now. Incidentally, I ended up doing a factory reset and the issues I was having with the battery drain and lack of email notifications have all been fixed! so I am fairly happy now!
that's good to know that there is no way back from 4.4 either, this will make me more cautious for any future updates!
peace out.

Knox: rooting, custom ROMs and kernels

*** AS I SAID EARLIER I WILL UPDATE THIS OP (Original Post) IN ORDER TO REFLECT ANY INFORMATION THAT COULD BE OF INTEREST ON THE SUBJECT ***
Hi there!
I have bought my device a couple week ago and since I did not know about knox, I just allowed Samsung to install the 4.3 update that was pushed to my device.
I have since decided I want a custom ROM on my phone, and when I started researching, I found out pretty quickly that knox may cause issues.
I don't really care about voiding my warranty, because I have now tested the device and made sure it is works, and I'm usually careful about what I flash.
The thing is, I have read so many things about knox that I don't know what's true and what's not. Unfortunately I don't have all the links to everything I've read, but i'll update this OP with the links later (some posts were worth reading and very interesting)
So, what I've read about once you've got knox:
- You cannot get rid of it (everyone pretty much agree on this)
- There are ways to root without tripping knox to 0x1, so you keep your warranty, but what about unrooting? Or do you just flash a stock rom not rooted? I guess you keep the bootloader as it is?
- even flashing stock 4.3 will trip knox (really? always)
- if you have knox, you cannot flash anything below 4.3, even custom ROMs, or you'll have issues with wifi, etc. (this is what I've read somewhere, what seems to be a fact is that if you try to downgrade the bootloaer to anything smaller then you may break wifi and other features)
- and it gets better: once you've got knox, if you flash a 4.4 ROM (custom, of course, since there is no 4.4 stock for our device yet), there's no going back to anything smaller (not even 4.3)
Some of the above statements are clearly facts at the present time, until knox is cracked, if it is ever, but some of it sounds like BS, or at least i hope it is, because otherwise I'm not about to flash anything :-/
And this is just the beginning, I'll keep updating this post, and I'll try to separate fiction from facts. anyway, feel free to comment on these and give me answers if you know things for a fact (no guesses please).
Now I gotta go, sorry!
Cheers,
fa
Edit:
You will find a lot of threads on knox especially in the Galaxy S4 and Note 3 forums. But I guess most of the info on how knox works is valid for our device as well (I9305).
A lot of people seem to place a lot of hope in one of the greatest Android devs: Chainfire.
Here are a few links with info on knox, for those who like to read:
http://forum.xda-developers.com/showthread.php?t=2447832
http://forum.xda-developers.com/showthread.php?t=2597774
http://forum.xda-developers.com/showthread.php?t=2569349
http://forum.xda-developers.com/showthread.php?t=2447832 <== This is actually a thread you want to follow. Very interesting, but there's a lot to read. If a solution comes to get rid of knox, that's probably one of the first places on XDA where they'll talk about it.
It would be great to know if there is hope to see a knox removal tool.
Meanwhile, I see the following different scenarios. Could you share your experience and tell me how it works for you? As answers trickle in, I'll update this post with the answers themselves or links to the posts where the answer is provided:
1) You don't have knox: lucky you, enjoy and DO NOT UPDATE TO 4.3 or flash a 4.3 ROM with knox bootloader, or you will one day regret it!
2) You have knox. So if I got it right, there is no way to change your bootloader, but there are various scenarios:
a) you don't care because you're happy with stock and no root (then keep moving, nothing to see here, I wonder why you are even reading this...)
b) you want to keep your stock ROM and default kernel, but you want to root. I have read many threads where it is said to be possible. WHAT'S THE BEST WAY FOR THIS?
c) you want to keep your stock ROM but you want another kernel: IS THIS POSSIBLE, and if so, WHAT KERNEL WORKS/DOESN'T WORK?
d) you want to get rid of the whole Samsung ROM, so you want to flash a custom recovery (CWM or TWRP) and a custom ROM/Kernel. So what works, and what does knox prevent you to do in that case?

This is an idea, fabecoool.There would be nothing wrong if someone is responsible for making a guide/tutorial/ to our terminals in version 4.3 Stock with all this questions.There are many people who are lost right now and this would be helpful.
Many people do not know that really brings the version 4.3 and this will help them not to get into trouble.

I installed miui rom yesterday that has android 4.1 and it actually work very well
I was running cyanogenmod 11 and flash it successfully

Flashing stock wont trip knox. Once ur on official 4.4 with new bootloader u wont be able to downgrade no matter where u come from. Knox or no knox. Official 4.4 will have a new bootloader which prevents u from downgrading. Sounds like apple doesnt it. Lol

Thanks hayabusa08,
Do you mean that you won't be able to downgrade to a stock ROM smaller than 4.4, or to a ROM (included custom ROMs) smaller than 4.4.
Anyway, it does sound like Apple indeed.

Yes u wont be able to downgrade to 4.3 or lower once yur on 4.4

Well yes, you're lucky. Especially if you care about custom roms, if you do, don't flash official stock 4.3. Even if you like the Samsung UI (touchwiz), I would recommand you find a 4.3 stock without Knox. Just look for it in the forum.

hi there guys, i had my galaxy i9305 updated to 4.3 and im trying to install a custom rom. When i go to download mode to flash a recovery, the device doesnt show up in Odin nor in Windows Device Manager(as unknown or as modem) anything.
OS: Windows 8.1
Stock USB cablu,
OS on the phone: 4.3 stock

Ya, so those months ago I was telling you all not to use Odin any more for flashing, unless you want KNOX...

I rooted my phone on 4.1.2, and flashed CM11 through CWM. Does this mean I have kitkat bootloader and can't downgrade to 4.3 roms?

Greetings!
There is a lot of paranoia theme Knox, from my point of view the only problem is the warranty for ODIN and flash an earlier version, I do not see another problem. However, those who want to return to a previous version do through recovery, I've done it many times and have not had any problems (have a look at my signature) those ZIP'S I've modified to share.

Unlocking/downgrading/flashing/OTA question

Hi all!
I've been reading all day about how to SIM unlock my I9305 UK 3 Hutchison 4.1.2, and I'm getting somewhere, but feel I've hit a dead end with the sources available online and here. If I've missed something obvious I'm sorry! Would really really appreciate some guidance on where to go next.
I need to downgrade from 4.1.2 to 4.1.1 to do the simple unlock trick from the phone dialer code, but the first impediment is I can't find any UK 3 Hutchison firmware for the I9305 anywhere, not on any of the main firmware sites (http://www.samsdroid.com and http://www.sammobile.com) or here on XDA forums, or using Google. Neither 4.1.1 nor later versions.
So first off, if anyone knows where to find that then I guess I'm sorted? Even if I found 4.2/4.3 then I think I could downgrade to 4.1.1 using any carrier's firmware, then sim unlock, then flash the newer 3 Hutchison firmware and be ready for OTA 4.4, right?
If not, I need to know the implications of flashing a ROM from a different region/carrier. I'm going to sell this phone, and Kitkat might be coming out soon, so I need it to be able to accept OTA updates, and this is what I can't find clear answers on.
The ROMs I can find are:
non-UK, non-3, stock 4.1.1 firmware at samsdroid.com, a few versions from different European countries, all from a particular Euro carrier.
And from here pre-rooted UK 4.1.1 EE carrier firmware. My reading suggests that the rooting shouldn't be a problem, that an OTA update will unroot it, which is what I want. But they're not 3 Hutchison.
So what 4.1.1 ROM is best to flash, and how do I get it to a state where it will accept OTA updates?
I think that covers it, let me know if anything isn't clear.
Many many thanks you lovely people!

The would be you best bet, I've run it and its great and although its says it's an EE Rom there is no carrier bloatware, in effect stock Samsung

Hi, thanks for replying!
I guessed this was my best bet, but can you or anyone confirm for me, what will be the situation with OTA updates after flashing it?
Thanks!
PS. Don't want to take any unnecessary risks here seeing as I can't find any 3 Hutchison firmware to use as a backup! If only I had that, I could experiment more...

Rooted phone OTA update may well fail on install and phone refuses to boot . See multiple posts .

Oh right, thanks for clearing that bit up!
So what about the issue of using another carrier's firmware?
If I use th EE pre-rooted firmware and unroot, or use the European firmware? Can I then receive OTA updates or do I have to do something or is it not possible?
Thanks

Just trying to interpret JJEgan's words. They cite 'multiple posts'. So I guess the task, when I'm at home, is to search for these posts and decide for myself if there's anything to it. Don't mean to offend you by not taking your word on it, but 1 is a very small sample size!

Multiple posts means multiple users have posted help OTA update has failed usually at the same % in every case phone has been rooted .
Obviously if other multiple users have not had a problem they are not going to post help i don't have a OTA problem due to root .
Searching may not be that easy as many users don't exactly describe a problem in the title .
Me try OTA no i never use stock but i have read the majority of posts on the I9300/05 forum to know that some have a problem with root and OTA .
If it is actually totally untrue better get RootSu to remove it in the sticky .

I have no idea what accusation you think I'm making against Liquid Perfection, and I'm fine with appearing like a newbie, my true identity.
Is there anyone out there who isn't a horrific internet cliché who knows what will happen if I flash a different carrier's firmware on my phone and try to OTA update??

Thread cleaned.
Please stay on topic.

For anyone coming across this in future: I decided to take the plunge and flash 4.1.1 EE software on my 3 network S3, and behold, OTA update worked just fine. No problems so far. Fingers crossed it stays that way!

Roosted now on 5.0.2, want to updated and re-root. Is this possible?

I want to update and reroot. I'm on build LRX22G.G9925WRU1AOC3, Android 5.0.2.. Can I update and then reroot? I found an article that states PingPong is no longer working for root. Have we found another way?
I want to upgrade to see if the update gets rid of the Cell Standby battery drain issue. Nothing I've tried has worked. Plus the whole Stagefright thing........
Thanks in advance!

The only build you can update to and keep root is the OE2 build. There is a thread in the development sub forum that explains how. If you want the stage fright bug patched you need to update to 5.1.1 which does not have root

I see that there is a Trailblazer ROM - is that what you mean? And do you happen to know if it addresses the cell standby issue?
There's two dev forums and I want to make sure that I'm looking at what you described.

This has radio improvements I know but I do not think it addresses cell standby battery drain.
However, if you want better battery with root, install a custom ROM.
My favorite is this one. http://forum.xda-developers.com/ver...rom-esl-extreme-syndicate-l-v2-1-9-5-t3194532

Downgrade EPG2 to DOK2

Hey forum.
Quick question, how would I downgrade my SM-N910T3 that's currently on EPG2 to DOK2? I've been having issues with 6.0 ROMS (Mainly Bluetooth sync with my car, getting a massive delay after a few seconds). I'd like to go back to Cyanogenmod 12.1 and stay that way. I've tried flashing the DOK2 firmware but I get the error "fused 2 > Binary 1" if possible, could someone provide with a legitimate DOK2 stock link?
Thanks

Tried following it to no success. On EPG2 bootloader. Hope the Note4 community is big enough to get AOSP ROMs to TRY and support Samsungs new blob structure. I have no idea what other devices it exists on. If a bounty starts I think I'd throw a few dollars in.
