Hello. This thread is mainly for questioning/research/knowledge, as I don't have any major issue with my phone right now. I had retail ar firmware 4.4.4 with locked LB, converted to 4.4.4 Retail BR, tried to install the ota, it didn't (because locked bl) and when I tried to go back to retail AR i bricked (downgraded for boot) and I couldn't flash it properly due to preflash validation error (locked bl) so I unlocked BL and now everything works fine, and I sucessfully installed the XT1033 OTA on my XT1032, runs pretty good.
I've been reading on the incompatibility between bootloaders of 4.4 and 5.0.
For now I will wait to official update for XT1032 and flash that, but couldn't you just use the reflash bootloader tool that is around this forum and flash a 4.4.4 bootloader and all the stock firmware files? In case I for some reason wanna go back for 4.4.4.
If you install 5.0 on a 4.4 bootloader using cwm, does it work correctly? If it does, why do they update the bootloader in the first place?
Is there any working custom recovery for L? or in development? In case In the future when the OTA gets released I wanted to flash viper4audio (I'm priving myself of that beauty that I used on old phones just for the locked BL [warranty brah] but obviously not a problem now..) or I could just root and use one of those zip flashing apps? (I cant remember its name)
Thanks.

you mean the hard brick when your pc only detects it as qcom-something? that's bad for you
I only softbricked mine luckily, but I'll let you know anyway I felt damn stupid when I couldn't boot my phone because of my sudden impatience after waiting months from this update, just because didn't wait a little more
iirc there are some methods on the forum I think using that tool I mentioned to get it back, good luck with that

I suggest you not to downgrade to 4.4.4 as of now. you flashed OTA and you are in lollipop now.. Enjoy.... And wait for official release OTA for Xt1032 and firmware files. Once it released, Devs will surely create flashable zips... then you can reflash your version lollipop... People reporting bricks and many dspaly issue when they tried downgrading it..

i see 3 topics too... That is awful cause mine is XT1033. i just convert it to GPE 4.4.2, OTA to 4.4.4. One sim works
So scary abt brick the phone cause i want to go back to stock 4.4.3
I mean 4.3 JB, not 4.4.3 KK =.=", it somehow felt a lot smoother in that version...But is downgrading possible from 4.4.4 GPE to 4.3 Motorola?
I was able to downgrade form xt1033 4.4.4 to 4.3 but don't have idea about GPE

Gpe makes change in bootloader and fastboot. So u cant downgrade via fastboot.
But if u have any nadroid of 4.3, u can revert back

I guess the point is partition.stock version use f2fs and gpe use ext4.so it have to reparttition if you want to convert a gpe to stock.but after OTA to 4.4.4 , the gpt.bin(stock 4.4.2) can't be flash.It's that right

Could you please tell me how? I've been looking for 2 days, so many people are trying to do the same thing and there is absolutely no information
My phone is xt1034 unlocked bootloader version 4111, received 4.4.2 and upgraded manually to 4.4.4 and would like to downgrade to 4.3 to hopefully solve the alarm problem and the internet connection stability, as these sometimes drive me crazy!
Thank you

how the hell did you do it? if you're on 4.4.3+ you shouldn't be able to downgrade your motoboot, and if you do it completely bricks the bootloader. i know because i tried. i tried the restore to stock guide but it didn't work on my xt1034.
K finally got back to 4.4.3 Stock, but still cannot make it to 4.3 (version downgraded for boot, partition and motoboot)

when you are on 4.4.2 u can try to go more in 4.3, should work, try with BR firmware if u got XT1032, or other region wich have 4.4.4 from whre u are starting to downgrade. then when you are in 4.3 just flash via fastboot other 4.3 region wich u want.

Thanks for your reply but it'll only works with 4.4.2, there's no way of downgrading it further to 4.3...
EDIT: I recall reverting from 4.4.2 to 4.3 a long time ago, which I forgot to flash the motoboot.img, which then caused a bootlogo loop (not boot animation loop). Is it the case here that motoboot.img can't be downgraded anymore?

i was on same bootloader loop,i bricked my phone wich same,i started to downgrade without searching a bit.i didnt known will cause a brick. in that post i explained how i succesfully downgraded from 4.4.4 to 4.4.2. When u are on 4.4.2 then it should work to downgrade one more to 4.3. for me it worked to downgrade till 4.4.2 , more i dont continued cuz i wanted just to go on 4.4.2 to convert in GPE again, but should work.

Yeah it worked like you said, but only for downgrading to 4.4.2, not 4.3. 4.3 rom required a different bootloader (i think) so with the upgraded bootloader which comes along with 4.4.3 and 4.4.4, it won't work anymore since the bootloader can no longer be downgraded.
There is a serious bug that Motorola have patched in 4.4.3 / 4.4.4. Not only is it very dangerous to mess around with downgrading / updating bootloader, but if you start experiencing the sudden battery drop issue you will regret ever having tried.
From my experience of updating and downgrading.
Once you update from 4.4.2 to higher version number you can no longer downgrade to 4.3. The lowest you can downgrade back to is 4.4.2 from 4.4.4. Also relocking bootloader doesn't seem to work while downgrading only works when re flashing the same stock firmware.

What if you went from 4.4.4 to 4.4.2, then from 4.4.2 to 4.3? Will that work? I am desperately trying to get back to Jelly Bean as I hate KitKat, but I am unable to as I went to 4.4.4 Stock Rom (XT1032, Retail GB firmware version).
Can you explain me how you did that?
Once Bootloader has been updated by flashing 4.4.2 or newer, there is no going back. Even with a nandroid backup, I suspect there is a check in the 4.3 kernel regarding Bootloader version and it won't progress. There was only ever one custom kernel for 4.3 made by @faux123, but I cannot locate it since he removed the download.
Here's the scenario:
I converted Moto G XT1033 4.4.4 to GPE 4.4.2
Then upgraded to GPE 4.4.4 and GPE 5.0.1, both by OTA
GPE 5.0.1 OTA ended up in softbrick
So now I cannot repeat the process beacause of the new bootloader, GPE 5.0.1 OTA brought with itself. And that bootloader would cause a hardbrick if I tried GPE 4.4.4 OTA on the device now
Questions: (No question is related to the other)
Would I be able to install Stock Lollipop OTA when I get one on 'Stock rom'? (I can revert to Stock 4.4.4) Would Stock Lollipop OTA mess up with the current bootloader, GPE Lollipop OTA has installed?
Is there any way I could flash Lollipop Stock image later, when it's available?
What can I do to set things right with the 'bootloader messup' that's caused right now?
Thanks, in advance!

You are another who has made a stupid mistake, you should HAVE READ MY THREAD!
You need to wait untill the Lollipop Factory images are published, then we can get a blankflasher and restore your bootloader.
Once your bootloader is working again, you can flash Lollipop without problems.
You need to wait 1 or 2 months.

Nope. I did read your thread after softbrick. And that's why I didn't install any OTA's after v5's.
I flashed 4.4.4. It's not an OTA!
I'm currently running 4.4.4 on 5.x bootloader.
Now what I'm asking is,
Would I be able to install 5.x OTA when I get it?
Before the factory image and all that thing.
PS: 5.x hasn't arrived for general public in INDIA yet. What I was trying was Brazil OTA.
Hi all,
I just tried to upgrade my old CyanogenMod from January to a recent nightly and got hit by an error caused by my old KK bootloader (http://forum.xda-developers.com/mot...uently-questions-t2996087/page24#post59520890). The guy in that thread offers a supposedly official Brazilian Lollipop bootloader, but I'm a bit hesitant 1) downloading something like that from unknown origin on the net and 2) I have a UK XT1032 (I think it was unbranded, bought in Tesco), not Brazilian. So what are my options?
Can I get the official bootloader from Motorola, by downgrading to 4.4.4 and then get the OTA? Or is it not available yet for my phone?
If I were to do that, can I unlock/root the phone again and get a custom ROM or is there no unlock yet for the Moto stock LP stuff?
What are my options, besides staying on my January CM ROM?
Thank you very much for any input!
You could manually flash the GB 4.4.4 stock ROM for the xt1032, update apps, take the 5.02 OTA update, and be running a Lollipop bootloader.
I just flash manually stock 5.0.2

Which version do you recommend for the xt1032?
Or, if you're skilled enough, just manually fastboot flash the tz, rpm, sdi, aboot and sbl1 partitions extracted from any 5.0.x OTA package for XT1032. I did the procedure on my 1031 (with corresponding files for the 1031, of course) and it worked nicely.

That sounds like a good plan. So
1) GB 5.02 OTA is already out for all XT1032 devices? I read somewhere else we're still waiting?
2) Is my phone still unlocked after this, i.e. can I install a custom recovery, root etc. and custom roms afterwards?
Thanks =)
The 5.02 OTA for GB ROM has been released from what I have read.
Once the phone is sim and bootloader unlocked, flashing ROMs, recoveries, etc. will not relock the bootloader or sim lock the phone.

That's great to know! My worries was about that flashing the bootloader could result in a newly locked one. Thank you very much!
hi, so i flashed the brasilian 5.0.2 version, its possible to install another 5.0.2 version without making a downgrade and unlocking the bootloader, i want to flash my original firmware (which is the mexican one) when lollipop comes out
If it was the flashable zip from @lost101, then yes, you are free to do so. Lost101 made flashable zips that do not mess with the bootloader and you can install anything you want afterwards.
If you flashed the entire brazilian firmware via fastboot then I believe your boot loader may be a lollipop one, and I'm not sure if you could go back to kit Kat stock (which would not enable you for being print for the update)
so you mean i have to make a downgrade in order to install a new firmware? its not possible to directly install the lollipop update from another region?
Well... Long story short
If you want to update the official update for your phone, you'll have to flash the full stock firmware in order to be prompted for a lollipop update.
If that happens, your boot loader will update to lollipop and the downgrading is impossible
If you use the flashable zips you can flash anytime, from any ROM, from any version
---------- Post added at 11:36 PM ---------- Previous post was at 11:35 PM ----------
The Brazilian and all other flashable zips here on the android Dev section from @lost101 have updating disabled, because they don't recommend boot loader update (if you want to continue using root or flash roms efficiently)
yes i know that, i flashed the entire brazilian firmware amd updated to 5.0.2, the thing i want to do, is to intall the mexican lollipop firmware when it comes out, without making a downgrade to KitKat

In your case, there should be no problem with flashing the Mexican Lollipop firmware when it is available.
If i downgrade my Xt1541 which has marshmallow stock rom on it , without flashing bootloader.img or gpt.bin , would that all go to plan ?
Also, if I accepted an ota update when on lollipop, would it hard brick my phone, and if it did , would there be a recovery method?
Because if I accepted an upgrade back to marshmallow via ota, surely it would not break the bootloader because it is upgrading to the one which is already there? correct me if I am wrong.
Thank you for any advice with this
I downgraded mine without flashing those two files and it worked perfectly and I see no reason why an OTA wouldn't work. You'll have to unlock your bootloader to downgrade though.
