Hello, i've been looking everywhere and i can't get an answer, i have this moto g 2014 (XT1063, single sim) on lolipop 5.0.2, the thing is than i want to downgrade it to kitkat 4.4.4 since i've lost aprox. 2hrs of battery life, but i can't find an exact copy of the same rom i have now(lolipop) on 4.4.4, this one works with any provider except Nextel, so i can put in it a Telcel/Movistar/Iusacell sim on it and work with no problems, it didn't include any provider apps
System Version is: 22.41.16.titan_retla.retla.en.01 amxmx
Compilation number is: LBX22.99-16
Can someone tell me if such rom exists, and if not, which one should i use to downgrade it and not lose the ability to use any sim?
Phone is already Rooted and the bootloader is unlocked.
First the the ROM never lock/unlock the phone bands.
If your phone is factory unlocked and don't work with some carrier it could mean that band isn't supported
I think any titan retla.retla will work but downgrading is always risk checkout for a downgrade guide
Hello ,
i bought samsung galaxy s5 at&t model a few days ago and i want to root it and flash new cm13 , boot i cant find anywhere how it can be rooted. its on 5.1.1 firmware. i was thinking , is it possible to downgrade kernel with odin and then root with towelroot ? i am just afraid of bricking my phone.
No, it's not possible to root this phone on Kitkat.
I got a Samsung S6 Edge (Verizon SM-G925V) today and heard I should upgrade to 7.0 (Nougat) firmware and hope it gets rooted soon. Is the baseband version I have root-able? It's G925VVRS4DQD1
To my understanding, the tool on autoroot.chainfire.eu WOULD work, but because the bootloader is locked down, it will brick the device instead? Is that true? Is there any hope that 7.0 will be rooted soon for my device? Any input on this would be helpful, thanks.

I tried it it said something about recovery not sure what but in Odin on the phone screen it said recovery fail
So do i. However, it won't brick your phone. One time i tried to upgrade to 7.0 or downgrade to 6.0, first boot i saw a pic of a lock is unlocked when i first boot. Next time i boot, it disapppears. Any idea?
I think this phone is unrootable for now since Verizon is like "you can't make it because i don't wanna my phone naked, haha"
Same problem here. recovery fail. How can I root my G925V Nougat?
I have a tab s2 sm-t710 on nougat T710XXU2DQCL that was installed OTA and would like to know if i am able to downgrade to 6.0.1. The device is 100% stock and was wondering if ODIN would give me any grief about downgrading. The PDA number of the 6.0.1 file is T710XXU2CPK1 (Cellular South).
Thanks
On paper, I think you should be fine. :angel:
I'd also like to know this as battery life seemed much better on 6.0.1 for me.
i did downgrade my T 815 from 7.0m to 6.01 using odin. didnt face any difficulties. i did a complete wipe/format after i downgraded .
Can you not downgrade with TWRP as well?

I used Odin and firmware downloaded from sammobile and it worked flawlessly. I've performed downgrades on over 100 tablets so far and they have all worked good.
Downgrded my t713 long time ago and didn't have a single problem, you just need to download a compaitable firmware from sammobile!

You're safe to downgrade as long as it's allowed. Older builds will fail immediately so there is no harm to downgrade.
I've seen a few people asking about downgrading. Whats the reason behind this? Is N glitchy?

N does not work at all well with DJI drone remote controllers. I foolishly updated my brand new SM-T719Y 8" and Now I cannot connect to my drone at all. I have an pre 2016 Tab S2 on Android 6.01 and bingo works.
This size pad is the preferred size for drones and has enough grunt to provide stutter free vision. Cannot comment on anything else about N as this pad will only be used for my drone...

Hi Beut,
I have been trying yo downgrade my Tab S2 SM-T719Y LTE from Nougat to 6.01 and have correct downgrade and Odin. Every time I try to downgrade it fails straight away, so I was wondering what you ment by "as long as it is allowed" & "older builds" will fail immediately.
I need to get this happening as I cant fly my drone.
Cheers Yts...
I don't have your model so it cannot verify. However, other models I can downgrade to older builds close to the Nougat.
Like SM-T580 or SM-P580, both are Android 7, QF1 and QE4 respectively. I can downgrade them to PL4 or PL2, Android 6 but not the PG1.
Q: 17 or 2017
P: 16 or 2016.
The second letter is the month it's released.
You also need the right bootloader, different OS has different bootloader. Many just flash the AP file only without bootloader, it'll failed when downgrade.
Is it possible that you cannot downgrade Nougat to 6.01 as every time I try on my SM-T719Y Tab S2 LTE, it fails straight away. I have tried 3 different downloads and all failed, but Odin will let me overwrite my Nougat with a downloaded version of Nougat from the same web location as I got one of the 6.01 firmwares from.
Here are my fail messages.

Is it me or is it this model of the Tab S2 SM-T719Y????
When downgrade to MM you need the BL ( Bootloader ) goes with the AP . Boot loader of Nougat is not the same as MM , however bootloader of LTE version is locked
Sammy doesn't want you to downgrade.. nougat is planned obsolescence, I'd say.

Hey I've been trying to downgrade my T719Y for days now. Constantly failing and googling everything I can to find where I'm going wrong.
How would I know if I have the LTE version? And if I do and the bootloader is locked, does that mean I can't downgrade?
If I don't have the LTE version, you're saying I need the bootloader and AP to downgrade? Where can I find the bootloader?
I'll keep searching and trying but this is wearing me down. Any assistance would be greatly appreciated. My surveyors can't do a damn thing with our giant UAV until I fix this
LTE version is the one that has SIM, usually it's next to SD slot. Most LTE versions have locked bootloader, that's why you cannot downgrade firmware.
I just kept an older phone for apps available only for 6.0. Like scr recorder. Otherwise there are no reasons to downgrade
Hi everyone,
Just got a used S5 from ebay and it's a carrier unlocked AT&T model (I'm in the UK). I've successfully upgraded to Marshmallow using Odin and was looking at root options. I've done some looking around the forums and just wanted to check if I was understanding the situation properly:
1) Are the AT&T models impossible to bootloader unlock?
2) If this is true then I guess any ROMs other than stock based are out of the question?
3) Is it not possible to have root on MM? Is this just because it hasn't been done yet, or is there something inherent in MM that makes it impossible?
4) Therefore, it's only possible to have rooted s5 on LP? And only ROMS based on LP are available?
Thanks in advance !
How did you update the firmware, since i'm having an AT&T S5 with 5.1.1 on it (G900AUCU4COI5), and when searching for updates it's always telling me that there are no updates available, although i'm sure that there are at least 10 mini-patches and patches (5.1.1 -> 6.0).
@tooplanx
Your assumptions are correct. There is an encryption key that has the bootloader locked down and only the carrier can release it. Most Samsung US variants are notorious for this. So yes only stock ROM or a 5.0 based custom ROM is available. Root could be possible through a security exploit on MM (especially since its security patches are now 6 months out of date) but I don't think any developers are working on it that I know of as most of them have moved onto other devices and variants. So at this time yes it is only possible to have root on 5.0.
@Cornul11
Are you using a working AT&T sim card when checking for the update? It won't appear when using another network.

Unless you have an AT&T working sim, you will need to install the upgrade with some software called 'Odin' and the manually downloaded stock 6.0 ROM for the G900A. Kies doesn't work either.
Have a look for 'Odin upgrade' in these forums, it should be easy enough to find.

I don't have an AT&T sim card, so no updates were being shown as available for me. I downloaded the firmware and installed it using ODIN, now i have the latest available version which is G900AUCS4DQD1 (6.0.1).
