[Q] Possible to downgrade XT1072(Thea) to KitKat/CM11? - Moto G 2014 LTE Q&A, Help & Troubleshooting

Hi,
The Bluetooth A2DP stuttering bug on Lollipop is unacceptable, and I have heard that KitKat users did not have the same problem.
Is there a compatible KitKat 4.4.4 factory image that I can use to downgrade my XT1072?
Cheers,
Sunkai.

Having looked into ROMs a bit further, I am now targeting getting CM11 installed on my Thea device.
This would not only eliminate the Bluetooth A2DP stuttering, but also remove the infuriating "increasing ringtone volume" setting that is baked into the factory image by Motorola.
Has anyone got CM11 running on their Thea device? I couldn't find an official build on the CyanogenMod web site.

Thea was never released with KitKat as far as I know, so finding a ROM would be unlikely, tbh.
I can't recommend the AOSP build (http://forum.xda-developers.com/moto-g-2015/development/rom-android-source-project-t3141139) enough, smoother than stock, no launcher redraws and no bluetooth issues for me (I use my bluetooth speaker every day for an hour or two).
The ringtone also doesn't increase, highly recommended with TK stock Gapps, basically turning your Thea into a mini Nexus.

Thanks for the recommendation. I will trial the ROM and let you know if it has fixed my BT issue.
With system storage space being such a concern on the 8GB Thea devices, does the AOSP build's "Move To SD" function work for relocating apps?

Yes AOSP does let you move apps, in fact I think it lets you move more of them. But as TK Gapps installs all the stock Google apps to the /system partition, I've ended up with a bit more free space on my device. Obv YMMV, but give it a go.

My initial impression is good. I have not encountered the extreme Bluetooth A2DP skipping that I experienced with the factory 5.0.2 LL image. It is unpredictable, and can take some time to manifest though, so if it does occur I'll report back here.
I wouldn't expect to get OTA updates for a custom ROM, so I assume that I will need to use TWRP to install any subsequent Android versions?
If I do this, will I lose all of my installed apps and data, as with the initial AOSP load?
Also, will I need to side load the TK stock Gapps to keep them up to date?
Thanks for your advice.

No, you won't get OTAs. You will flash updates to your phone the same way you just did, via TWRP. keep an eye on the thread for update notifications and changelogs from the devs. Don't flash different ROMs over each other without a factory reset, or a "full wipe".
When updating a ROM you will only flash the update and NOT need to factory reset, that way you retain your data. Clearing the cache partition can help with initial crashes or problems you incur afterwards.
Yes, you can load the gapps and keep them up to date if you wish, TK's generally see updates on weekends. This is however optional and totally dependent on you bandwidth availability etc.
I generally just download and reflash one gapps package. Until there is a big change in the Gapps, then I'll update mine. Check the relevant thread for more flashing instructions.
Hope it helps. Also, backups in TWRP are a good thing to have.

Maybe useful to note here, that I got my moto g 2nd gen xt1072 with kitkat loaded on it.
Bluetooth stuttering not occurring at all, it started with lollipop
So the stock kitkat rom must exist !

Can I install Lollipop or Marshmallow stock on this device? And it'd run smooth or it's better to use other ROMs?

Nothing? No ROM images?? Come on!

There is NO stock KitKat ROM for thea (XT1072,XT1077,XT1078,XT1079).
Lollipop update was a huge one with deep changes and I don't recommend downgrading a device to an earlier version that the one it was sold with.
On other devices, the bootloader is not compatible and downgrading can brick the device.
According to these reports, it seems KitKat custom roms can be installed but it is not recommended !
As Thea doesn't have any kitkat rom, I suppose you took it from titan ? (Titan = no-4G variant)
Don't forget that Thea (XT107x) is a DIFFERENT device than Titan (XT106x,I think).
It doesn't only add 4g, it has a different Soc (different processor...), a different battery. So Titan ROMs are not compatible with Thea. End of the line.
Some may work, but are not made for it.
Flashing a titan ROM on thea is just like flashing a galaxy S6 ROM onto a Sony xperia Z3. They are different devices.

Yes you can. But prefer roms like Cyanogenmod it's clean you install gapps (any version you want).
It's far better than stock ones

someone has cm11 for mto g XT1078 thea ? if please have me send the link to download please

there is no stock kitkat and also no cm11 for this phone!

This link a picture of the moto g 2nd gen without LTE
The variant without LTE can be downgraded to KitKat because it was released with KitKat.
The variant with LTE was released with lollipop and CAN'T be downgraded to KitKat.

Not possible. Although Titan and Thea share the same board, bootloader restrictions and source tree changes will not allow you to boot CM11 or any KitKat code, let alone a full ROM. Try CyanogenMod 12.1 or 13 instead, although you have to unlock your bootloader and install TWRP. It has many improvements over stock Android without losing stability and even gaining some speed. Also most CM kernels for Titan will work in Thea as well. I am currently running CM12.1 snapshot and it's butter smooth with zero bugs.

They are variants of the same motherboard AFAIK, same camera, same CPU and GPU and resolution, same SD unit, but on the bootloader and RIL level they are fully different. Some kernels can be cross-flashed, and even some Titan recoveries boot on Thea (although a very bad idea with zero good results) ROMs must be adapted to the full board and cannot be cross-flashed.

[INFO]WARNING: Android 5.0 Bootloader and Kitkat Compatibility

Android 5.0 (Lollipop) Bootloader and KitKat Compatibility​
Everyone wants Lollipop, however it is worth considering some of the possible consequences of upgrading via OTA update.​
Bootloader:
A new Bootloader (BL) will almost certainly be included in the OTA update. It is also very likely no KitKat Kernel, stock or custom will be able to boot properly with the 5.0 BL. Perhaps the Kernel DEVs can find a workaround.
Root: (ETA: Unknown)
It may take some time to gain root access on Lolipop as on other devices this has required a custom Kernel. A custom kernel itself may require kernel sources to be released - something that has taken weeks / months in the past.
Xposed Framework:
Developer has said he will wait for CyanogenMod based on Lollipop before properly starting development of an ART version of Xposed. CM12 may take a few weeks to release. Expect to do without Xposed for at least a month, probably longer since root is also required (see above.)
Custom Recovery:
This has not been an issue before, but it is always possible a new Bootloader could break compatibility with existing Custom Recoveries. Obviously, you would not be able to restore a CWM / TWRP backup without a functional custom recovery; but even then, it is unlikely you will be able to boot your KitKat backup.
Custom ROMs:
This is another area that could be affected by a new Bootloader. It is unknown if existing custom ROMs will require new Kernels / system changes in order to work with the new BL - something that could take days, weeks or months.
Performance:
Currently the performance difference between KitKat and Lollipop is unknown. If the first release of Lollipop for Android One has performance issues, you may be unable to revert back to stock KitKat.​Possible solution:
Wait for a flashable zip [NOT OTA Update zip] of Stock Android One Lollipop ROM - this would mean your Bootloader remains at it's current version and potentially allowing you to change 'back and forth' between Stock KitKat and Stock Lollipop. However, it is currently unknown if the newer BL is a requirement for Android 5.0 Kernels.
This is taken from the Moto G thread and all credits goes to @lost101.The sole motive of this is to create awareness about the new bootloader included in 5.0
Thanks For The Info @DC07 :highfive:
Thanks For The Information Bruda !!
This thing is only for device like motorola, samsung etc.. As I never saw same thing for nexus.. Motorola does not allow to downgrade so they update bootloader in every android version update.. I dont think it will be same for sprout
Let it arrive ,no point in discussions on thongs that are not confirmed

Nope. The bootloader was updated on my nexus 7 flo for the 4.4.2 OTA. Since this update is much bigger I think we'll have a bootloader update too.

No, there is no rom out in the public. I did have a test version that booted, but it had the same problems as with CM10.1. No sound, GPS and SIM. Everything besides that did work just fine. But u can't call it a phone anymore .
It is just to difficult without some proper sources to build one.

Moto G 2014 XT1068 became very slow after upgrade to v5.0.2

Hello everyone,
The phone worked fine with version v4.4.4 after the upgrade (v5.0.2) he became unbearably slow.
I do not know too much about root, rom and and so (last time I change rom it was on my HTC Desire ).
Generally I would be happy if there is a simple way (or at least a detailed guide) to restore the phone to the version he came with.
I would appreciate your help :fingers-crossed:
If you want to restore to stock 4.4.4
Then go to the general section of this phones forum and search for your model and the firmware (4.4.4) you want. Then just follow the steps to restore. (I can't tell you which firmware since you haven't mentioned your phone model). Or install CM 13 Official, it's stable as hell, and its better than stock. (Guide to flashing roms also exists).

Thanks for the quick response.
My phone model is Motorola Moto G 2014 XT1068 as appearing in the title, any additional information needed to specify ?
About CM 13 Official from what I've read here and in other places It seems like if it not stock there be problems like camera does not work, low battery, problem with SMS and so... Or is it only in certain versions ?
Sorry. I didn't read the title properly.
This link : Stock 4.4.4
There's no thing wrong with CM. It's better than stock for sure and there's no additional problems seen when you use CM. Just don't flash Xposed.
Its stable and fast even though it's in Alpha stage.
Thank you !
You have any idea how do I know whice fireware I need ?
A) Firmware KXB21.85.14 (earliest version)
B) Firmware KXB21.85.23 (DSDS ALL)
C) Firmware KXB21.85.27 (latest version)
D) Firmware KXB21.85.23 - GB Region (UK)
E) Firmware KXB21.85.14 - DE Region (Germany)
Depends on your country.
A and B should work on ANY XT1068 as it's a Retail for ALL Dual sim, (it may or may not have certain languages)

Android Nougat Custom ROMs?

Hi what is the state of these Android 7.0 custom ROMs I have seen some available but what are the current bugs?
Does the camera work and etc?
I tried compiling using the instructions here: http://developer.sonymobile.com/ope...uild-aosp-nougat-for-unlocked-xperia-devices/ - ended up getting a "(remote: size too large)" on the userdata.img, and couldn't boot the phone. I might try again some other time, see if I can get a basic build working.
Has anything changed in the last month?
The Xperia Z3 Compact looks like my ideal phone... but not if there's no support for new ROMs on it.

Fast Nexus 7!!!

I have found a fast rom for the 2012 N7, I went through CM12.1, Omnirom 5.1.1 and 4.4.4, Lineage 14.1, RR 5.8.2, but none of these were good, with or without custom kernals or parrot mod. The best rom I've ran (and am currently running) is stock 4.1.2 with no mods (unless you count root). Happy flashing guys, and frankly, if you don't want to update your hardware, just downgrade your software. I also tried stock 4.3, 4.4.4, and 5.1.1, 4.1.2 is the best by far. It took an hour to settle but when it did, it was lightning compared to the others.
Also no, I tried CM 10, it's somehow slower than stock 4.1.2

Before buying my 2012 N7 3G (I bought it some months ago) I've read the same on some forum. I use this rom base on 7.1.2 and it is acceptable for me.
I believe some apps/versions are not compatible with 4.1.2 by now, so it may require a bit of digging for apks no?
What I do notice, is that if you want a fast tablet you have to carefully choose your apps (and maybe versions) due to ram consumption. From example as an app for e-reader: Kindle (127mb ram) vs fbreader (27mb ram).
Since you had all the work trying roms I guess you may have choosing apps. Do you have any recommendation?
So far I can tell some apps that I believe are the best/lightest that I use:
k9 email material
xodo pdf
nova launcher
opera beta (may not be the lightest, but it has facebook notifications and messenger notifications so minus two apps I need)
greenify
amaze file explorer
hope to ear from you, right now I am in need of a good keyboard (I am a fan of swiftkey, but it seems somehow slow in my Nexus 7 3G with 7.1.2)
