(q) mk2 aosp

I just recently rooted my Samsung galaxy s4.i purchased it the other day and it's running MK2 I was able to use safe root to do so. I also have safe boot installed as a recovery. My question is, how can I install aosp roms? I couldn't find any information on this. The only roms safe boot supports is stock. Where do I go from here? I am new to s4 so please be nice. Thank you so much.

Its to bad you didn't get the S4 back when it was released or earlier last summer when it was shipping with MDL firmware. This firmware allowed us to use loki and install any custom rom we want, including pure kitkat. Maybe you can trade your new one for an MDL one.

Well. ... Is there a way that I could downgrade my firmware and root from there?

I wish you could. Devices running MF3 firmware or higher blew an eFuse when they upgraded from MDL firmware. There is no way back. AT&T and Samsung are doing everything possible to make it so we can't root or flash custom recoveries. It's beyond disgusting how much AT&T goes out of its way to stop us from getting into our own devices.
I'd recommend not purchasing the AT&T branded devices from here on out. Let's hope that the international version of the s5 supports AT&T's LTE bands.

Latest Update for AT&T I337?

You're currently on mdl firmware. This firmware allows you to put on a custom recovery and flash roms. Are you sure you want to update? You will no longer have the ability to put on a custom recovery.

Yes to all your question.....i337MK2 tar md5 contain 4 seperated files ( first released ) follow the image guide where u have to place into ODIN SLOT ....the one that said combined ALL IN ONE ( newest released ) mean that u just flash into PDA ODIN SLOT ONLY.....just follow that guide on second post it would get u to latest ATT MK2 4.3 firmware. But like @jd1639 said with MDL firmware u can install anything even 4.4.2 rom and also there is alot of custom stock rom without ATT bloatware out there that u can install .....goodluck and PM me if u need more help. FYI if u got helped by someone please hit THANK button to show your appreciation ....:good::good:

I'll update my S4 to the latest update and you can send me yours. I'd kill for mdl firmware...

Yes it contains all the bloatware, another reason not to upgrade and flash custom roms.
Edit, it has not been mentioned yet but one you upgrade you can not go back to a previous firmware.

When I upgrade to MK2, does this mean I will need to perform factory reset and all my existing app will be gone or will the app remain on the phone even after the upgrade.
I will do the backup before the upgrade but at the moment when I connect the Phone to the PC, it would mot pick up so maybe I will need the latest software driver, is that correct? I have the same problem with Kies which does not recognise when phone is connected.
Any suggestion would be great.

Not always, most times a factory reset is needed to clear the phone of old apps and data. Root, is lost, but apps that require root can still be present which can become a problem when root is no longer available.

Why doesn't your friend flash a custom rom instead

He wants a stock touchwiz ROM. If their is a custom ROM based on the latest firmware then by all means direct me to it and I'll flash that for him. Thanks.

He's on mdl which allows a custom recovery and easy flashing of roms. If he upgrades to mk2, the latest, he'll lose that ability. Try this http://forum.xda-developers.com/showthread.php?p=47713264

Right, we have a custom recovery and an unlocked boot loader and I flashed an older build of that Google edition ROM, but he just really wants the ability to move his apps2sd. I didn't see a mention of the apps2sd feature in the change logs. Thanks for replying so quickly.

[Q] Downgrade from OE1?

I just switched back to my GS5 because I broke my iPhone 6. I am currently running 5.0 Baseband G900VVRU2BOE1. I've been trying to Odin back to KItKat. I get a fail in Odin every time. Is there something going on with the bootloader that prevents downgrading?

It sounds to me like the aboot qfuse counter changed which would mean that there's no going back to any previous FW. It was only a matter of time before they did it since the VZW S4 lollipop update did that.
We won't know until we get ahold of either the update.zip or the odin tar. I have 2 VZW S5's and both refuse to tell me there's an update available even when I Odin back to a stock FW.

Nice. That's what I hated about Apple. You own the phone, yet, still can't do what you want with it. Well, thanks for checking it out.

It's most likely more of a Verizon thing than a Samsung thing. Although with the 5.1.1 S5 update on T-Mobile, the kernel prevents rooting and T-Mobile phones are on unlocked bootloaders which means they don't care if you root or install a custom rom so maybe it is becoming more of a Samsung thing now.

the thing is, with Verizon, you can choose to not accept the upgrade a few times, but ultimately, it is forced on you...which is why I rooted my S5 the same week I bought it (to avoid unwanted 'upgrades')

You can't root g900a on Lollipop as of right now. AT&T locked the bootloader when they released 5.0 BUT.. you can downgrade your phone to KitKat. Then root it using Towelroot root and then flash a prerooted lollipop rom using flashfire Here is a link with a bunch of people that downgraded there g900a to KitKat and how they did it and worked around everything: http://forums.androidcentral.com/samsung-galaxy-s5/489071-tutorial-downgrade-samsung-galaxy-s5-5-0-4-4-kitkat-6.html This will help you out in starting the root process on your phone.

This is not true. If you are running completely stock lollipop either becuase you purchased the phone with it on it, or you took the ota it is not possible to downgrade to KitKat, you will brick your phone. If you were rooted on KitKat, you can update to a prwrooted lollipop, which I am running now for example, and using that method allows you to downgrade as well with no issues so long as you don't take the ota. This only applies to the g900a.

Also not true.. You can downgrade your phone from 5.0 to KitKat DEPENDING on the version of bootloader. That will make or break the whole possibility of downgrading. Check the link I posted and read through the forum. It has been done by multiple people but the general consensus is if your phone's bootloader is past a certain version you're screwed for now and if you can't downgrade and root but you want to in the future I would suggest not updating for a while until there is a method of rooting your current version bootloader.

I did check the link you posted and only found people that tried it on a g900a unable to downgrade. There was no time that you could go from stock L to KK on the g900a.

To be quite honest dwade. You can save yourself a lot of headaches and stress by putting your phone on craigslist and getting yourself the g900f unlocked that way you can avoid all of these processes and the risk of bricking your phone lol If you're looking to root and get into modding your phone, AT&T & Verizon phones are the worst when it comes to locking things down.

It's certainly the case for the F variant that towelroot only works on 4.4.2 that was compiled before the end of June 2014......If there is a build that matches these conditions for the A variant, towelrooting may be possible.....If not, I guess you'll have to try CF Root or similar...

You have to sell your phone and buy an i9505. Then you can install TWRP or CWM on your Galaxy S 4.

I believe the ATT version of the s4 has a locked bootloader so flashing TWRP or CWM is not possible atm.

Is there any way to perform a nandroid-style backup/restore then?
I'd like to flash the latest stock ROM but would like a return path to what I currently have now if things go badly.

I would check out the Verizon s4 forum to confirm whether your bootloader is locked. If it is locked, there's very little you can install in terms of ROMs. Not sure about TWRP or CWM.

It's easy, if you have updated your phone to a newer version of Android, then your BL is locked.

NB1 4.4.2 is My Official ROM. I Updated It To NJ4 4.4.4 Using Android System Recovery And Then I Updated It 5.0.1 Lollipop Via Same Way.
I Think My Bootloader Is Locked.

Bootloader on LP is definitely locked.

So What Should I Do "audit13"

Once the bootloader is locked, you will need to use safestrap to flash files. Also, you'll be limited to tw-based custom ROMs.

Hi Dude.
Whats Up?
I Have Bought Samsung Galaxy Note 3 (SM-9005)
I Have Rooted It But I Want To Downgrade It To It's Official ROM And Than Update It Step By Step After Rooting My Device.
Whats Your Opineon About.

All you need to run OTA updates is use the unroot option from the root program and have a stock recovery. OTA updates will not work on a rooted system.
The quickest way to update your phone to the latest ROM would be to flash the lastest stock ROM from sammobile and then check for OTA updates.
