Question: Rather than incrementally update from 4.4 to 4.4.2 by OTA, can I just wait until the full 4.4.2 image is available and flash the full image?
I see a nice list of firmwares here, for example:
http://sbf.droid-developers.org/phone.php?device=0
I'm reluctant to do the update incrementally via OTA or manually, because I don't want to revert from TWRP to stock recovery. As things stand, I believe have a non-stock recovery is preventing me from receiving the OTA that TMobile is currently rolling out.
I have a DevEd GSM and am using TMobile. I'm entirely stock except for TWRP.
Thanks.
Once the US TMobile is available for 4.4.2 you should be able to fastboot (or mfastboot for the system.img) flash the update without losing your recovery. I'm sure someone will post specific steps to update unlocked bootloader, custom recovery phones once the 4.4.2 image is released. I have seen posts warning about not flashing the boot image because it can't be reverted, but I don't know if that affects phones with an unlocked bootloader.

It does affect the unlocked bootloader people, that is why some people are waiting for the sbf. If you update via the OTA, it will install the new bootloader, regardless of lock status. Once on this new 4.4.2 bootloader, it is impossible to flash any stock images before 4.4.2 (you cannot go back to 4.4 or 4.4.2).
But why would you want to go back if you have an unlocked bootloader already? I don't really see any reason to flash an image that is earlier than the latest... if I were Moto, I would let people flash the earliest system image of that version of android (4.4 kitkat in our case). This would rectify the root situation (because 4.2.2 isn't kitkat), and it would keep the people happy as well.

You absolutely can manually flash the system image while having the 4.4 bootloader, you can also flash any 4.4.2 stock based ROM such as the 1052 European ROM that showed up today.
I was actually running the gummy ROM 4.4.2 while still on the 4.4 bootloader without any issue

I have rooted every phone i've had and for some reason the MOTO X is confusing me! The phone is a bone stock developers Ed. 4.2.2 pre camera.
I am confused as to which jcase method to use or if there is another option.
I am guessing PwnMyMoto 1.4.3 verizon. but i'm not sure.
Any help would be fantastic.

PwnMyMoto and jcase's methods are for locked bootloaders. You first need to unlock your bootloader. Then you need to decide if you want to take the OTA to 4.4 or not because once you upgrade to 4.2.2 post-camera, you can never downgrade to 4.2.2 pre-camera without bricking your device.
If you want to upgrade to 4.4, here are the instructions to unlock and gain root:
[STEP-BY-STEP INSTRUCTIONS] Unlocking and Rooting a Dev Ed Moto X Running Kit Kat
I have read of others who kept the 4.2.2 bootloader and other partitions and just selectively flashed those partitions they wanted as each new upgrade's sbf firmware was released. I don't know what advantages there are to doing that.

It's a Developer Edition. Take all the updates available (4.2.2 camera update, 4.4 and now 4.4.2). Get the unlock code from Motorola and unlock your bootloader. Once that is done, flash twrp recovery and then install root via twrp.
Very simple on Dev Editions just because you can unlock the bootloader and flash an alternate recovery (twrp, cwm, etc..).
I agree. Unlock your bootloader (Doesn't void warranty on Developer Edition), flash TWRP recovery, then boot to TWRP and install/flash SuperSU. And it doesn't matter what ROM version you're running. (there is a TWRP for 4.2.2 and one for 4.4/4.4.2).
As mentioned, the bootloader included in the android versions can prevent you from downgrading the rom version. (i.e. bootloader in 4.4.2 prevents you from downgrading to any previous ROM). Why would you want to downgrade? If you have a locked bootloader, you'd want to downgrade to be able to use the root processes needed when you have a locked bootloader. But if you have an unlocked bootloader, because you can flash an alternate recovery (not possible with locked bootloader) and root no matter what ROM version you have installed, the only reason to downgrade would be if you encounter a bug you can't deal with that isn't present in the older roms.
because 4.4.2 fixes the exchange and bluetooth issues, and doesn't introduce anything new, its suggested you update to 4.4.2 if you have an unlocked boot loader (4.4.2 isn't rootable on locked bootloaders and may not be, so its recommended that those with locked bootloaders who want to root stick with 4.4).

From what i have read 4.4.2 isn't rootable at all. Even if you have an unlocked bootloader. Is that correct?
Great info, thanks.
I thought that the Verizon DE already had an unlocked bootloader? Or is it like an HTC where i have to go the the MOTOROLA webite and get a code?
I did something like that for an HTC ONE i have on straight talk. I unlocked the bootloader from the HTC website, then installed TWRP, and then rooted and its running a 4.4.2 ROM that is great.

Ok, so i have my phone unlocked, updated to 4.4 and for some reason i can not flash the TWRP.
I get the error (bootloader) variable not supported!
Any ideas.
I have tried both mfastboot and fastboot and i get nothing.
I also moved all files into another folder and CD into that folder and still the same error.
Can i install the TWRP with goo manager?

did it finish flashing? mine says that when i flash a recovery also, but it flashes.
after you flash it dont reboot, just go into recovery (volume down to move the selection, volume up to execute)
then select reboot system, and it will ask if you want to root.

i recently bought a bell xperia z1, went on to the sony website to unlock bootloader to find that mine is locked, unlike the international version which has an unlockable bootloader.
ive updated it to see if the updates would unlock the bootloader but alas they did not, now im running :
model c6906
android 4.3
build 14.2.A.0.209
Main question :
Will i be able to downgrade and bypass the bootloader?
ive rooted a S2/Htc HD/ Desire Z in the past im just worrying about bricking my phone that ive had for less then a week.
and all other guides ive seen are for different versions, ive heard of flashing the 6903 stuff but that makes me worry way to much.
so pretty much want to know is it possible to do via downgrade to achieve root or should i just wait till a safer method becomes available.
sony bloatware is annoying
Yes, you can get C6906 Rooted with Locked Bootlader. First you have Read a bit more about it, starting with this thread and also watch the Video Tutorial.
You have to use Flashtool v0.9.15 to downgrade to .534 using Rogers FTF for your model from here.
When you are on 4.2.2 FW .534 Root it with Bin4ry Method, then Install Dualrecovery, SuperSU and Upgrade to your favorite latest Android Pre-Rooted, like KitKat Here or JB 4.3 Here.
Done.
Good Luck!
you sir are the man, followed the video and got root, now to find a rom to use.
edit : went to install a rom + gapps and had to do the whole process over again. right from flashing nuts custom. got stuck in a sony logo boot loop. zz
so attempt #2 with a different rom.
edit 2: was able to update to 4.4 kitkat so now i hope i can update my rom. since i was trying to do a 4.4 rom on the 4.3 firmware ?
edit3: nope stuck on sony logo so went back to nuts again... hrmm well atleast i could upate to 4.4 going to try boot to cwm and see if that works
Before I flashed mine I was reading for weeks, You did in few hours and I think to quickly. If the phone stuck in Boot logo, I think you did something wrong but I don't have the phone with me so I cannot tell.
Now you have to go back to stock, keep pushing Volume UP and Power, 3 vibrations, phone in off, keep pushing volume down and connect to pc in flashmode, flash a Stock FTF for your model from the link I give you. Now you phone should boot. Repeat the process to get Root and be careful.
Remember to Wipe Data, Appslog, Cache, every time you flash a Fresh Installation is recommended.

You should not connect the phone to the PC until the PC prompts you after flashtool has prepared the files for flashing

Ok, that is why I saw in Flashtool Disconnect and Connect my device few times but never had a problem. Good to know.
i was able to go back and use flash tool to flash nut's ftf
so im on 4.4 kitkat rooted which is good.
but when i flash any custom rom trough any recovery it boot loops im guessing its because locked bootloader.
so im guessing any rom i want to flash has to have 2 parts. The flashing process in recovery and the flashtool flash firmware for that rom.
unless like you said update my kernal
Hi i just read about the i9295 and the i537 and they are the same device accept the different in the frameware version (the i9295 - 4.2.2, i537 - 4.4.2).
so i have the question can i install the i537 4.4.2 stock rom on the i9295?
and if not i'll be happy if you can explain why (just so i can understand).
thanx ahead! :laugh:

While the i9295 and the i537 have the same hardware, they have different software. More specifically, the i9295 has an unlocked bootloader while the i537 has a locked bootloader. What this means is that the i9295 is able to flash/install a custom recovery, custom kernel, and custom ROM while on the i537, in order to flash anything it must be signed by Samsung. Only official firmware is signed by Samsung, so there is no way to flash a custom recovery or custom kernel. There is a way to flash custom ROMs, but that's not important here.
To answer you question, theoretically you could flash the i537 firmware on your i9295, but you will most likely end up with a bricked phone because bootloaders are only compatible with their intended models. So the i537 bootloader will only work with the i537 and will brick the i9295.
If you still really want the i537 4.4.2 firmware on your phone, I'd be more than happy to trade my i537 for your i9295. This is a great phone and works great in every respect, I only wish it had an unlocked bootloader like the i9295. If I could do it all over again I would have bought the i9295 instead.
EDIT: I think @mythi is working on a stock 4.4 ROM for the i9295, you might want to ask him about it.

Hi thank you very much for your answer it helped me a lot.
and about the locked bootloader, are you sure that it can't be revert?
and one more thing i bought this phone like two weeks ago so what is the best custom rom for now? (i saw only the carbon rom 4.4.2)
and one more question, if the i537 4.4.2 is signed by samsung but with locked bootloader and the i9295 4.2.2 is also signed by samsung and with unlocked bootloader so cant i just flash back the i9295 framewere over the i537 framewere?

Once you have a locked bootloader, the only way to get another bootloader on the phone is to flash one that has been signed by Samsung. Samsung uses a different signature on unlocked bootloaders, so there is no way to revert.
I don't think you really looked? I just opened the Development forum and found the following on the first page:

The just flash it to the phone. To simplify the way the bootloader works, it is the first thing that loads when you power on the phone, it then tells the phone what other pieces of software to load (aboot, sbl, kernel, etc.).
With an unlocked bootloader, it does just that, it loads the next piece of software during the booting of the phone. With a locked bootloader, the bootloader checks the signature of the next piece of software to load, if the signature matches the signature that the bootloader expects then the next piece of software loads. If the signature doesn't match, then booting stops.
When you flash something to the phone using Odin (currently the way you flash bootloaders), with an unlocked bootloader Odin will flash it, for better or worse. But with a locked bootloader, the bootloader checks the signature of the file you are trying to flash and if they match then it can be flashed, if it doesn't match then the flash aborts without any changes being made.
So, how can Samsung put an unlocked bootloader on the phone without it being signed? When you start with empty hardware you can essentially put any software you want on the phone, there is nothing there preventing it, but once you put a locked bootloader on the phone if will then check every single piece of software you try to flash to the phone.
TL;DR Think of the hardware as an empty room. You can put anything you want in the room to start with, but if the first thing you put in the room is a door with a lock, then the only things you can put in the room from then on are things that have a key to that lock.

NONONONONONONO ... never ever i say never ever repeat what u said in here ... flashing a other devices bootloader will destroy your phone and you will need something called jig to fix it ... this happens because every device that sammy realeses has a private key for certain partitions on the mmc like the bootloader the rbm etc ... flashing other devices partitions even if the share the same hardware (yes) even if they are from the same family will kill your phone and you will end with a paper that need 200$ service . i request you to edit your comment since alot of the people here are noobs or have little knowelge .

I'm going to edit my post, but I'm also going to disagree with you. Back when I had a Samsung Captivate you were able to flash Galaxy S i9000 ROMs with some minor tweaks. Inadvertently I accidentally flashed an i9000 one-click to my i897. The flash finished and my was messed up, but not so bad that it made the phone unusable (i.e. buttons were mapped incorrectly and the display was inverted). I discovered I had installed an i9000 bootloader on my phone because the partitions were different and I couldn't boot the phone after flashing i897 stock firmware. The only way I could get stock firmware back on my phone was to flash i897 bootloaders which lead me to believe that my phone had the i9000 bootloader on it. Maybe I'm wrong and maybe Samsung has changed the way things work in the past 4 years, but I do not believe this was always the case.
That said, I will make sure that everybody understands that they could brick their phone if they flash a different bootloader.

Well the captivate is another story the developers got a leak of a signed rbm of the chipset of (i suspect) the humming bird chipset ... when you have something like that minor modifications can be done ... the same happened a while ago with some 8xx and i not sure of the 6xx -which runs in our phones- the leaked rbm would help devs to make other variants easily compatible in the low level side .
bootloaders :good:are also different story ... each and every device these days has a private key as i said earlier this key gets checked before booting by something in chipset (hardware side) and if key mismatch the device will enter a qcom mode for debugging etcetcetcetc........
trust me you don't want to brick a 600$ for simply to flash a bootloader :good:

Thanks for the info. So here a related question, what would happen if you took an i9295 with 4.2.2 on it and flashed the i537 4.2.2 firmware minus the bootloader? Would it fail to boot due to partitioning or would it work?

NONONONONONONO ... never ever i say never ever repeat what u said in here ... flashing a other devices bootloader will destroy your phone and you will need something called jig to fix it ... this happens because every device that sammy realeses has a private key for certain partitions on the mmc like the bootloader the rbm etc ... flashing other devices partitions even if the share the same hardware (yes) even if they are from the same family will kill your phone and you will end with a paper that need 200$ service . i request you to edit your comment since alot of the people here are noobs or have little knowelge .

hi man i dont think you right because my last phone was xtreamer joyz which is the exact same phone as the newman n2 and i could install both official framewere with no problem and those two phones have the exact same specs and also the i537 and the i9295 so i think it should work just fine.
but my knowelge isnt good as yours so correct me if im wrong here but i think it should work
EDIT: I still asking my question but also joining to Devo7v question about what will happen.

If we get a way of unlocking the bootloader we can do this ... I will explain further ...
A stock Sammy ROM comes in the form of a tar.md5 package the .md5 part holds the signature of Sammy , this signature is a type of code that makes the bootloader understand that this package is a signed one with a Sammy key ... When we take the bootloader out of The package (sbl1.bin , sbl2.bin and sbl3.bin) we have to take other parts such as the rbm after taking these we have to repackage the remaining parts in a new tar package ... After doing this we can sign it with an md5 key but this key will give missmatch errors during flash so we have to get the keys of Sammy ... Even if we find those we will have find away to unlock the bootloader to unlock more things

I have to say that i didn't really understand why i cant install the official samsung i537 over the official samsung i9295 because the both signed by Samsung.
like if i have flashed the i9295 4.2.2 official stock on my i9295 so i can flash the i537 4.4.2 official stock no? they both have the Samsung key no?

I don't have any idea what must be done ... But I need to investigate more on this .
I am currently on 5.1 but work for at&t. I just put my work email on my phone that also requires a monitoring service called mobile iron that monitors my phone. My company now thinks my phone i rooted because I have "prerelease" software on my phone and am in danger of getting in some pretty serious trouble. I talked it over with my manager and they're giving me time to fix it, but I need to get off 5.1 as fast as possible.
I can't root and I can't unlock bootloader but I need to get off 5.1.... can i just flash a 5.0.1 ota zip? Really not sure what to do but don't want my company phone taken from me. all my clients know this number.
Thanks in advance

I think the only way to downgrade the version is to flash through the bootloader or flash a custom rom but you can't do either, but 5.1 is officially out so its no longer pre release software.
You have to unlock the bootloader to flash anything. No you cannot flash an older ota (ota patch existing files to new versions, not replace entire files) and as mentioned l, 5.1 is not pre-release.
How did you get 5.1 in the first place?

At&t hasn't approved the software I guess, so by their standards it's considered prerelease. I honestly don't see why it's even an issue, we use the exact same images that gpe versions get so it shouldn't matter. Not sure what to do at this point.

I just installed it as an update.zip using adb. No unlock required.

FYI, AT&T have no control over the update process. The update comes directly from Google, for all carriers. As long as you didn't install M or I, you're fine. There is nothing that AT&T could do to prevent anyone getting the update. Except maybe sending a memo out to a staff saying "you'll receive an update from Google. Please, please, please don't accept it"

Id say get a tmobile sim card and use that and that way they cant say your on lre release software since tmo just pushed the 5.1 update.

Again, the carriers don't push the updates. They all come from google. Its not the same as other OEMs like Samsung

Can't you root and go back to 5.0 and relock bootloader and reinstall the mobile iron app?

Doesn't need root. He could unlock the bootloader, willing the device and then flash the system.img and ROM.img for a 5.0 ROM. Then relock
But its pointless. 5.1 has been released to both versions on the nexus 6. The north American one and the international one. AT&T do not.control updates going to their "branded" nexus 6 device. They're coming from Google directly.
Edit..
Hmm maybe I'm wrong...
http://www.phonearena.com/news/Turn...akes-a-little-extra-effort--heres-how_id67599
Maybe like tmo, Google will be releasing a different 5.1 for at&t. This is disappointing news for nexus devices.
So yeah, unlock BL and flash system.img and boot.img from 5.0

Its not a different 5.1, but they delay the updates. As soon as the update is apppved it won't be considered "prerelease" and everything will be fine. It's a complete formality. But, it is what it is. I guess I'm going to just pull my email off my device and hope the "trackability" breaks. Not willing to risk boot loader unlock as I'll have to give the device back at some point. Again, as long as I don't put any "at-risk" firmware on the device and relock it shouldn't make any difference, but it does.
*sigh*

You can unlock the bootloader and relock it (so long as you check it boots first). There isn't a flag or trip or anything that they will see.,

Oh, I was thinking the boot loader status would show "relocked" when in fastboot
