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.

FFS, Did you actually read my post. I said NOT to Downgrade the bootloader while downgrading to a previous stock version via fastboot.

My bootloader is currently unlocked and I want to relock it. I have an XT1064. I've tried downgrading to 21.11.17 and following the instructions for KitKat but it never works. What can I do?
Unfortunately I have yet been successful doing this. I think it's because some parts of the firmware can't be downgraded. I keep getting pre flash failure
i did just for kicks... and was successful on XT1069.
from what I understand when this problem happens, is related to the ROM you used to do the process that is described in this thread follow these step with a ROM that is perfect and will succeed.
I did with the good xml ROM for my device and it was perfect.
try other ROM xml file... all i now here
One thing, to receive an OTA is not need to be with bootloader locked...
But you must have a untouched original ROM and Recovery installed on the device...
So no root original ROM and recovery just that.
I say this because many worry that is need to have a locked bootloader to receive OTA, and is not.
Have you tried locking after being on 5.0 firmware
I don't remember (i think was 4.4.4 to 4.4.4)... but i will try (5.0.2 to 4.4.4 and lock it) and report. OK, maybe today if not tomorrow...
In theory is the same friend of my did form 5.0.0 to 4.4.4 no problem...

Pretty sure you can only relock 4.4.4 bootloaders (motoboot.img) with the oem lock
If you have updated to a lollipop 5.0.x bootloader you cant downgrade from a 5.0 boot loader and hence cant relock it (yet?)

You can downgrade if use a ROM or a backup to update. the bootloader will remaining the same.
I dont know if you update via OTA to L if the OTA is updating the boot loader...
But yes you can downgrade from 5.0.x to 4.4.4 regards the bootloader if did not update don't see way will not re-lock, if update the OS and bootloader maybe because will not recognize the OS and ROM even if it is all original, but i think it should...
I will tested and report... downgrade and re-lock the bootloader... But my bootloader is the same version it did not update because i use a ROM or a TWRP backup do upgrade to L.
I will update the ROM i using do a clean flash, before i will try the downgrade and re-lock process. :good:

yeah i'm talking bootloader I know you can go up or down between 4.4.4 roms and 5.0 roms , i've tried mfastboot, fastboot (different versions) as people say 'only this version works' and so far not found anything that works
Ever since I upgraded to 5.0 then downgraded 4.4.4 I can not lock the boot loader. I don't think anyone will be able to until there is 5.0 firmware

You can read it above, you can do it if you are on 5.0.2. If you are on 6.x you have to be careful not to downgrade the bootloader and never ever update via OTA!
(Infos about downgrading android versions here: http://forum.xda-developers.com/moto-g-2014/general/xt1063-t3018818
But if you´re on 5.0.2 you should be on the safe side.

You can read that in the link given above:
Lollipop 5.0.2 to Kitkat 4.4.4 : If your bootloader version is 4882/4883(Lollipop Bootloader), you need to make some changes while flashing the ROM manually.
- Download Kitkat 4.4.4 Factory Firmware image zip.
- Unzip the contents.
- Delete the motoboot.img file inside the extracted contents..
- Do not type "mfastboot.exe flash motoboot motoboot.img" while flashing the Kitkat 4.4.4 firmware image manually.
4. If you downgrade your bootloader version i.e flash a 4883 Lollipop bootloader on your existing 4886 Marshmallow bootloader, your phone will be hard-bricked / permanently dead. Therefore follow the instructions above carefully. I am not responsible for dead phones.
You´ll find a lot of infos about that in the general section. Read all that carefully, downgrading stock is a tricky thing.
I personally would flash a custom rom.

That´s right. But never upgrade via OTA again then because OTA doesn´t care about bootloaderversion and will hardbrick your phone.
If you down/upgrade stock rom you´ll have always to spare out boot.img (if you do it by using the commands one by one or if you do it by script. You have to delete the flash boot.img command out of the script/tool then).
This is only relevant for stock roms,custom roms doesn´t have this problem.

That´s what´s written in the "[GUIDE] [Titan] [MM, LP, KK] [Unlock + Root + Backup + Restore + Downgrade" thread and that´s what I know about that.
motoboot.img is the bootloader and if you don´t touch it you should be on the safe side.
I personally am on custom roms since 5.0.2 and have never flashed/downgraded/upgraded a stock rom again so I have no personal experience.
If you wanna be 100% sure ask @SharkcpN, the one who wrote that thread.
You can safely downgrade by skipping motoboot.img while flashing.
Once you downgrade to a lower android version, do not install any further OTA updates of higher Android version else it might lead to hardbrick. After downgrading, go to Settings > Apps > MotorolaOTA > Disable it
If you want to update to a higher android version, flash the higher android version ROM via fastboot mode only.
I was just wondering if i can go back from stock ota updated 5.0.2 to 4.4 kitkat with my twrp backup without problems ?
You can downgrade to 4.4.4 without issues. But I never tested such thing using TWRP backup, but, as far as I know, KitKat bootloader is different of Lollipop, so you may brick some files in your Titan. If you really want to downgrade, do it properly, by downloading DSDALL firmware and then, using fastboot to order the commands. If you want to automate downgrade process, you can use my tool that you can take a look here. You still need to download the stock ROM apart, tough. xD
Ok thank you very much. Guess I'll have to use titanium backup and fastboot then. Will definitely check your tool

No you can easily downgrade using twrp.. Just wipe system cache data and dalvik cache and restore the system, data and boot of your kk backup.. You should be good to go
Flashing the firmware will surely brick your device

You cant downgrade your bootloader, and yes you cant use custom 5.1 roms with kk bootloader But anyways, your bootloader is already upgraded, so it doesnt matter. And be careful about one thing, don't directly flash a STOCK kk rom on a lollipop 5.1 rom. Always downgrade to a stock based rom, and then do it.. CM11 based roms can be flashed directly (with wipes of course)

But i saw your RaR rom and i think i will just flash that. I'm really sorry to ask again and waste your time but will i be able to flash other non-stock based lollipop roms then ?

I highly recommend you do the ota update before flashing any ROMs, because it will update your bootloader, and avoid issues After you get your BL updated, you can freely flash any ROM of your choice, just make sure you do a clean flash
And no you are not wasting my time

Currently my bootloader version is 48.83. I dnt remember what it was on lollipop. Pls help!
Just use your backup that you made prior to upgrading to Marshmallow. If you don't have the backup, just flash a different ROM. Plenty of guides on the site.

I have made the backup. But i have heard about many people hard bricking the phone when trying to downgrade and then again upgrading via ota. Thats why i askd.
If u are on custom rom other than motorola marshmallow soak test ota.. you will not get ur phone bricked when downgrading. Hard brick occurs if u downgrad from soak test ota to lollipop. In your case u just need to flash retaildsdsall firmware via fastboot mood. Search for tutorials for reverting to stoc 5.0.2.
Just DON'T CHANGE BOOTLOADER. You shouldn't be able to downgrade bootloaders but Motorola screwed that and with M bootloader you "can" downgrade, but bootloader downgrade results in BRICK. Just flash the rom you want, EXCEPT THE BOOTLOADER. For custom roms you shouldn't have problems.

All I can say is that I was on Nexus Experience 10.0.4 (Marshmallow) but could not get adopted storage to work so restored my previous AOSP lollipop ROM from TWRP backup and no issues. My Bootloader is 48.82. I have never used the soak test version or OTA version of marshmallow.
I have also in the past restored stock lollipop V5.0.2 from other lollipop versions with no issues.

Just don't downgrade your Bootloader and you should be fine, if you're using an easyinstaller script to flash stock Lollipop make sure and remove the lines of code that flash motoboot.img & I'd also recommend removing the line that flashes gpt.bin to be safe.

The easiest thing to do would be to unlock the bootloader, flash recovery, and just install an Oreo rom (I recommend AOSP Extended) and Google apps
you could just flash an 8.x oero rom so there isn't anything to "downgrade" in the traditional sense.Also these Moto phones need sGSI and not just GSI , i think so.
tnx
