Has anyone tried downgrading? Does it work? If you downgrade then take the ota again, does it brick?
I am thinking about flashing the EU firmware then upgrading to kitkat, but want to be sure if I can downgrade since I would like to later install the firmware from Chile instead of EU.

The only thing that can get you into trouble is the gpt.bin. And maybe it doesn't even get u into trouble. The gpt.bin was the only one that got flashed in the update.zip that can break the phone afaik.
So downgrading to JB should be possible. But for the safety, remove the gpt.bin. If u can get the chili ota after it i don't know.
Off course this is at your own risk

I updated my Motorbike X XT1058 for 4.4.4 (KXA21.12 VZW_XT1060_4.4.4-KXA21.12-L1.26_1FF) and it wanted to do the DOWNGRADE for 4.4.3 or 4.4.2. Some way for that?
The GPT.BIN in 4.4.4 is different from 4.4.3, which is different from 4.4.2, which is different from 4.4.0's.
Motoboot.img is different between 4.4.3 and 4.4.2. 4.4.2's is different from 4.4.0.
These will prevent a complete, successful and safe downgrade of the rom version.
If you've seen all the "don't downgrade or you'll brick" warnings, this is what its talking about.
This ^^^
But a better question is WHY would you want to downgrade?
I did not like because of the modification Verizon

Well, you really can't downgrade without great risk.
So better to live with it, or try the Chinese seller and unlock your bootloader for a fee. Then you can root, and change things that you can't change without root. Here is a long thread about the unlock code seller...

Actually you can do something that is risk because everything is a risk you can take and you never know what can happen but here it is: you can flash the 4.4.3 or 4.4.2 or 4.4.0 update over the 4.4.4 by using minimal adb flash tool and then just flash the 4.4.2 or desired version over but DO NOT FLASH THE gpt.bin!!!!!!!!That will screw up everything so after you flash everything but the gpt.bin you should do a cmd to reboot then you will be on the downgraded version!!! I'm not responsible for any bricked phones OK I tried this and the it worked for me so yea its a working procedure that YeS is a risky task so be careful!!!!:laugh:

First this is an old thread...
Next, skipping gpt.bin and/or motoboot.img(or its components) HAS been a cause for bricks, and when it didn't brick, it caused extra bugs (like trying to go App Drawer -> Settings -> Security kicks you back to settings menu... and some having issues toggling wifi on/off... and some who tried skipping gpt/motoboot when applying the 5.1 update also had speaker phone issues).
For more, see the link in my signature on downgrading..

My mistake you need to flash the 4.4.4 gpt.bin over the 4.4.2 gpt.bin so the device thinks your flashing a 4.4.4 firmware but in reality your flashing the 4.4.2 firmware..I think its easier to use RSD lite to flash the firmware but you need to do a couple of modifications to the 4.4.2 firmware.All you got to do is move the 4.4.4 gpt.bin to the 4.4.2 firmware then flash it if you get the moto.bin error just do the same step as said above with the gpt.bin but with the moto.bin file..Hopefully it worked out for you ?

Not sure why you are quoting me saying "hopefully it worked out..." as I'm not the one trying to downgrade.
I can assure you... mixing GPT.BIN/Motoboot.img parts from one Stock rom, with the GPT.BIN/Motoboot.img of another STOCK rom is not a good idea.. it has been cause for bricks and/or features not working correctly.
To suggest otherwise, without acknowledging the risks, is irresponsible, especially if you take some time to search the forums and see all the posts of people who have either soft or hard bricked their device while trying various processes to downgrade. And especially if you are someone willing to help those who have bricked following your advice.

How can you downgrade from 4.4.4 to 4.4.2? I did try to downgrade the XT1060 Verizon,but it cannot be done,did try all options cut a line here ,edit a line there but still end up with the same 4.4.4 version.The idea i have is to downgrade to 4.4.2 and the use the sunshine to unlock the bootloader and after that to flash any ROM out there ,but never upgrade back to 4.4.4...Any help would be helpful...
Best Regards!

It all depends on what rom you wanna flash if you flash cyanogenmod 12.1 you'll get the Lollipop update if you flash Cyanogenmod 11 you'll get back to kit-kat.

But you should know Sunshine developers charge a fee of 25 bucks to unlock and it works but you need to have a pay pal account and enough money for it

its documented in the sunshine thread that once 4.4.4 is on your phone its too late. even if you manage to downgrade it without bricking, the parts sunshine relies on will already have been patched and cant be downgraded. so downgrading wont help you to get sunshine to work
I just got my new Moto X 2014 2 days ago. It came with KitKat installed on it. I remember that on the Moto X 2013 that downgrading caused a lot of bricks. Is this the case with the new 2014 Moto X? Also, has anybody downgraded, then taken the OTA again and it still works?
During the downgrade process would I need to flash all the parts? Or do I need to skip some?
Have you read this thread? http://forum.xda-developers.com/moto-x-2014/help/lollipop-to-kit-kat-t2986044
Yes I have but it didn't answer all my questions. For example if upgrading via ota will cause a brick? If it's necessary to flash all files or if they all can even be flashed.

I downgraded to kitkat and took the OTA to lollipop with no issues. When downgrading, you don't really have to skip any commands. If you try to flash an old bootloader (as was the case when I downgraded to kitkat after getting the newer bootloader from the OTA, well, I think it was a newer bootloader anyways), it will just fail to flash. No harm done, at least not on my XT1095). You can skip flashing the bootloader altogether, which is what I did the first time I downgraded to kitkat, and I had no issues.
Thank you, I took the plunge and installed lollipop. I was worried about downgrading since I was not sure if everything would work or not. So far so good.

I would like to know if the process is the same downgrading back to kitkat from lollipo 5.1???
Hi, I already have te brazilian 5.1 OTA installed on my xt1097 but in my country they released 5.1 few days ago. I wonder if I could have my country softwt but the only roblem is that I have to downgrade to 4.4.4 and the directly install the OTA to 5.1 because they jumped directly to 5.1 in Argentina.
I want to know if there is any risk of hardbrick if do this in the proper mode (I have the bootloader unlocked and I know how to downgrade but beacause it is to 4.4.4 I have the doubt o fwhat could happen if I do it).
I thin that this could be very usefull to other users that are in the same situation that me.
Thanks in advance!
Yea there is a risk of bricking. The downgrade to 4.4.4 then taking OTA's has caused many brazilian moto x to brick.

Even if the ota update is to 5.1 directrly?
I´m asking becasue i have understood that the problem was due to the vertsion of the bootloader.

The issue is due to the boot loader version. The OTA updater script sometimes fails to check for the boot loader status and flashes/bricks anyway. There is no guarantee if you downgrade to 4.4.4 and take 5.1 OTA that you will brick, but there is no guarantee that you will not either. Just take it through MDM and be safe. MDM will do the proper checks.

with no brick at all.

The brick is not when you downgrade. The brick happens when you downgrade then take an OTA. Don't take an OTA or you risk bricking it.

You are saying that if I do the downgrade succesfully and then I upgrade to 5.1 by MDM y will have 5.1 with no brick risk ?

Correct. Because MDM doesn't upgrade the phone like an OTA. MDM flashes the complete images.

Hi all,
I know it's a known issue on Android. But my question is another.
I've a Moto Maxx from Brasil with locked bootloader. Is there anyway for me to maybe downgrade and afterwars upgrade again ?
I don't know if this can help with my problem, but maybe worth the risk. My battery is not lasting one day with normal use.
There's a way, but you need to unlock the bootloader.
You'll be re-flashing all of Kitkat EXCEPT for gpt.bin. (That part cannot be downgraded.) You will then have KitKat back. You can also then upgrade back to Lollipop.
But if you mess up the flash, you can brick your phone if the bootloader is not unlocked.
IF your bootloader is UNLOCKED, then you just go back into recovery and re-flash again. Everything can be fixed if your bootloader is unlocked. If you try flashing with a locked bootloader, it's much harder to fix mistakes, if they can be fixed at all.
Go here and read. Be sure to thank @Jaocagomez for writing the tutorial...

Hello
I have a moto g titan xt1068 dual sim which was originally running stock lollipop 5.02 and was updated with the OTA stagefright update and then the OTA MM6.0 official by motorola.
I have since installed custom roms cyanogen 13.0 and cyanpop 6.2
I know my bootloader is now the latest, so my question is can I now only install MM based roms? or can I still install KK & LP based custom roms?
or will installing LP or KK based roms hard brick my device?
Many thanks for any help
i'd like to know it too...
I'm not sure, but I can't really see why not. The bootloader being the latest changes jack squat on the question of being able to install older versions of Android or not. I mean, I WAS able to install the stock LP ROM on the MM bootloader, but your mileage may vary.
Yeah you can. Just don't try to downgrade your bootloader while downgrading to previous stock Android version. Itll brick your phone.
But just flashing custom Roms is safe.

That's bullsh-t.. You can always downgrade your rom, but you have to be sure you're not downgrading your bootloader. So if you're using oneclick installer you have to remove the command from the script which will try to downgrade your bootloader. Also after downgrading you have to be super sure that you will not update it with OTA!
Btw.: I'm not sure downgrading through fastboot can even brick your phone.

That's right.. You can touch your bootloader only when you have to upgrade it, for example in case of updating to Android N. Which I think will never happen (of course officially).
Here you can find a nice guide to downgrade your Android version.
