[Q] Bricked my Moto X - can I resurrect it?

My Moto X now refuses to boot. With stock recovery it'll get past the bootloader, then blink an image of a dead android with the message "Error" briefly, and keep doing so every ~10 seconds. If I flash TWRP, any attempt to boot takes me to TWRP, with log messages reading "unable to mount..." for a bunch of partitions (/data, /cache, storage, etc.)
Can I recover my device?
The short sequence of events: I rooted my phone (T-Mobile phone, unlocked it via Motorola's website) and installed TWRP. Later I tried to accept the 4.4.2 OTA update, but the phone wouldn't take the update, because TWRP. Flashed stock recovery tried again, got stuck in bootloop. Tried flashing back the 4.4 / 140.44.3 images from here, now I'm stuck with a blinking error message.
I see there are a bunch of image files bundled into the 4.4.2 / 161.44.25 update - would flashing those do any good?

What version is your bootloader?

Version 30.B2.

OK, you still have the 4.4 bootloader so you should have no problem flashing the full tmobile/retail/dev edition build of firmware. I'd perform a full flash with rsdlite or with fastboot using all of the commands in the xml file in the same order. Do not skip any files or bypass any files if there are errors.
This will reset your phone and wipe all content!

Did you attempt to clear dalvik and cache, I believe you can do it through fastboot
Fast boot erase cache should work . its trying to flash the it's ,so you need to delete the cache where the ota file downloaded to

so here is abit more help here are the full firmware links
T-Mobile 4.4
http://sbf.droid-developers.org/download.php?device=0&file=2
that is the file you need to flash with RSD Lite or Fastboot and it should get you 100% back up and running.
But then if you want to go to 4.4.2 after you flash the firmware before you add anything or install TWRP just update the phone to 4.4.2 then install the custom recovery and SuperSU.

I have tried both RSD Lite, and applying all of the commands from the XML file manually, following the directions from here. Both ways, I still get the blinking error message

The "can't mount..." log messages I get if I flash back to TWRP suggest it could be some sort of partitioning problem, but I'm not sure how to diagnose that.

And the flashing of all files completes successfully?

I could have sworn that I wasn't getting any errors previously. Now, however, after trying to flash system.img (making sure to use mfastboot, of course), I get an error on the phone, "sp space is not enough". Not sure what it means, and Googling around doesn't turn up any answers.

Ouch, it does kind of sound like the partition table got damaged. I suppose you could try "fastboot erase system" and then try to flash the system partition again.

So I guess more warnings into my noobs guide to accept an ota thread
Maybe I should put a notice not to accept the ota and only flash your carriers sbf firmware when available?

Well, that was very weird. In the bootloader I scrolled through the menu and accidentally selected "Factory". No idea what that's supposed to do, but now my phone boots again! I'm going to really, really, hope I don't break it again...
I want to try the 4.4.2 update now, but given I'm not really sure why my device works again I'm scared to.

Good for you, I would wait for the sbf firmware to be available to flash, seems to me a safer way of getting the update

I'll go with that plan What is it that makes flashing from sbf safer?

So if you perform a full factory reset the phone will boot up normally now? If that is the case then I don't see any problem with accepting the OTA to 4.4.2.

Help PLZ
I had the exact same problem as OP, took the same course of action, and got a successful boot. I do some minimal stuff, check if everything is working, turn on dev mode, etc. I put in my wifi password.
I wanted to check if my bootloader was back to stock, so I turned off my device, and then tried to power on. Pressing the power button does nothing.
So I get into fastboot, and select factory (reset) again. It boots up, but it doesn't seem like it actually did a factory reset, because it automatically connected to my wifi..
Have you any idea what's going on, and how perhaps to solve this weird dilemna?
EDIT: I'm not sure if I actually did anything, but after a couple reboots it just started working normally. I installed the update to 4.4.2 and everything is smooth thus far.

Eventually the phone prompted me to apply the 4.4.2 update so often the phone was actually unusable - it'd go back to the "do you want to update?" screen as soon as I backed out of it. I was thus forced to apply it OTA. Fortunately, the update went through fine this time, and my phone continues to work fine
Thanks for your help, folks!

[Q] Rooted 4.4.2 with locked bootloader factory reset safe?

Hi, I have a republic wireless moto x I just successfully rooted and updated to 4.4.2 from 4.2.2 with a locked bootloader with no write protection (wp)
Since I updated it to 4.4.2 I have this error that pops up that I can not resolve
"Unfortunately, the process com.motorola.process.system has stopped"
I googled several pages of several website results and several pages of google but can not find the solution.
Solutions found was to:
Safe Mode (I tried this first with no apps installed on non safemode and non system apps updated, didn't work and popped up even on safe mode)
Change date & time method (didn't work)
Wipe Cache (didn't work)
Wipe Cache & dalvik cache (didn't work)
I am debating about factory reset but unsure if it will make me lose my root because I have a locked bootloader (if that matters in anyway I am still new to this, and that my moto x is from republic wireless not like other carriers with unlocked bootloaders).
Please help me and discuss with me how I can get rid of that error.

You shouldn't have done it. You obviously didn't read or follow any of the guides here or you would have known better.
There was ONE (very tricky and convoluted) way of retaining root and it involves SafeStrap.
Sorry to say - there will likely be no root in your future.
A factory reset will most likely not help. You will have to download the 4.4.2 SBF and re-flash the entire stock rom.
There's a guide here: http://forum.xda-developers.com/moto-x/general/guide-moto-x-return-to-100-stock-using-t2446515
^ This is the only way to get your phone back to being usable again. MAKE SURE you do NOT try to flash anything but 4.4.2. Flashing a prior version will likely permanently brick your phone.
After this process, the ONLY way you're going to obtain ROOT is to unlock your BL.
I hate to hear this happened to you, but its posted -all over- this forum that you cannot take the 4.4.2 OTA if you are rooted on a previous version. If you had followed the guide, and used Safestrap, you would be OK.....but now its too late. Once you've flashed the 4.4.2 OTA, it updates the bootloader, patching all of the exploits we used previously. Game Over.
Good Luck

I did not have a root before 4.4.2. And I did not take the 4.4.2 OTA. I did follow the guide and have used Safestrap and still have it. What do you mean flash the 4.4.2 OTA? You mean installing it through the update notification? Well I didn't do that if that is what you meant. I flashed through the using the guide to get me no WP, root, and 4.4.2. So am I still doing it wrong?

Sorry for the confusion...
Hmm...you didn't mention safestrap in OP - just that you "successfully rooted and updated to 4.4.2 from 4.2.2"
OK so if you followed the guide exactly your bootloader should still be on the JellyBean bootloader.
Assuming you followed the guide, you can start over. If you're ABSOLUTELY SURE you didn't update to the 4.4.2 bootloader, then I suggest starting from scratch.
Use RSD Lite to restore the 4.2.2 (JellyBean) rom (Again, you've been warned. If theres any possibility you flashed the 4.4.2 bootloader last time, this WILL brick your phone) Also, be careful to NOT flash the 4.4.2 ROM, or you will NOT be able to root as this patches the exploit.
Just follow the guide step-by-step: http://forum.xda-developers.com/moto-x/general/guide-republic-wireless-moto-x-kitkat-4-t2738233
The first step is to restore back the 4.2.2 stock rom, so this is where you should start. Don't forget to re-install safestrap and MotoWpNoMo as described.
Please let us know how it works out.

Aslo, before I start to do the RSD Lite to restore the 4.2.2. Is there any other way how I can identify what is causing that error "com.motorola.process.system"? And isolate and get rid of that problem somehow or finding that stock app and preventing it from doing that?

Its extremely difficult to know why you are getting the error, but if you RSD Lite and start over, it will fix this issue.
Far too many people are running safestrap and not receiving the error. Likely there is a file on your device corrupted somewhere. RSD Lite will fix it as it completely restores the all of the partitions.
Just go -slow- step-by-step, and post here if you get confused or have questions. We will get your phone back to normal...
On another note....if you have $45 laying around, I highly suggest you email the gentleman from China. Once unlocked, you won't have to go through this long drawn-out process. You simply SBF back to stock, fastboot flash TWRP, and you're done. TWRP will install su-installer for you.
Your choice. The BL unlock method is best because you have permanent access and can never lose root.
Safestrap method will work as well, but you have to be very careful to not accept any new OTAs until the devs find a solution and post it here.
Good Luck.

Woops I responded to another post but I am going to expect my bootloader code.
What is the first step from all of this that I should do?
1. SBF = what exactly? Hitting the factory reset button?
2. Fastboot Flash TWRP ? So after SBF. Fastboot Flash TWRP is done in AP Fastboot screen? Stock Recovery Screen? Or what screen exactly?
3. Did the guide I do didn't safestrap (twrp?) installed the su-installer for me as well right? Just wondering.

1.)
You can find the sbf files (stock rom) here: http://sbf.droid-developers.org/phone.php?device=0
Download the correct file for your carrier and try to flash with RSD lite.
You can find a great guide here: http://forum.xda-developers.com/moto...using-t2446515
PAY CLOSE ATTENTION TO STEP 4 - editing the xml file
If for some reason that doesn't work, let us know what carrier you are on and we can help you with manual flashing commands for your specific carrier.
Basically, an SBF is a complete STOCK image of the original filesystem (all partitions). By SBFing, you will be 100% back to factory stock. This method (SBFing) will actually fix a corrupted filesystem.
A "factory reset" does NOT do this. I highly suggest you do the SBF back to stock, and not try just reseting. If there is corruption, reset won't fix it.
Don't bother setting up any apps yet or setting up the phone. Wait until you complete the entire process.
2.
Yes! You'll flash TWRP from the "AP Fastboot" screen (bootloader).
UNLOCK YOUR BOOTLOADER FIRST. Otherwise you won't be able to flash TWRP custom recovery.
Now unplug the USB cord, and power off your device. Hold down the VOL DOWN button, and power back on. You will now be in bootloader (fastboot) mode. Plug the USB back into the phone now.
You must have "mfastboot" downloaded. You'll type:
mfastboot flash recovery twrp_file_you_downloaded.img (obviously replace with the actual filename)
You can find complete instructions here: http://forum.xda-developers.com/moto-x/development/recovery-unlocked-twrp-2-6-3-1-android-t2534850
P.S. If the download link for TWRP in the original post does not work, look near the end of the thread. Someone else re-uploaded it.
3.
Its entirely possible that something went afoul during your flashing process. I doubt the guide is to blame, because nearly everyone reported success. Sometimes things just go wrong...?
Good Luck.

On step 1. It is republic wireless 4.4.2 that I should download right. Correct me if I'm wrong.
Also is there RSDlite for mac or similar software? I tried to google it and xda'd it but I don't think there is. Or any other way to flash it into it.

If you have already received your code, yes, you should flash republic 4.4.2
If you haven't...just wait until you have it for sure. Once you flash 4.4.2 theres no going back. As long as you get unlock code, this is no problem....you'll be able to root regardless.
But, if for any reason he doesn't have your code (unlikely), you'll never be able to root once on 4.4.2....
As of right now (If I understand you completely), since you followed the safestrap guide, you SHOULD be on the jellybean bootloader, so the steps would be different if you didn't have an unlock code (and wanted to retain root).
Don't worry about any of this until we know for sure if you can get unlocked. In the unlikely event you don't get a code, post back here and I will step you through it.
Otherwise (if you get code), yes, start by using RSD Lite to flash the Republic Wireless 4.4.2 SFB per my previous instructions.
EDIT:
Just read the part about being on a MAC. AFAIK, there is no RSD Lite for Mac. We will have to go another route, unless you want to install windows inside a virtual machine....The dev that created the Mac Tooklit sold his X, and its no longer supported.
We will just do manual flashing...make sure you downloaded the "mfastboot" and followed all instructions on the RSD Lite thread I linked, EXCEPT follow the "Manual Flashing" instructions instead.
Extract the Republic Wireless SBF zip file Put the contents in to the same folder where fastboot and mfastboot are located. Here are the commands you will type after booting your X Into bootloader (Fastboot mode):
***Notice that mfastboot is used to flash the system.img. DONT try to use regular fastboot. Just type these commands one at a time.
fastboot oem fb_mode_set

So what you showed me on manual way was if I was to install virtual windows right? Also that link showed it was 4.4 not 4.4.2... so am I still good or I shouldn't do that method? Thanks again for your effort.

No. What I showed you was the manual fastboot method. This will run on Mac natively. You'll have to download the android SDK for mac, and install, then download the mfastboot binary (either 32 or 64 bit) here: https://gist.github.com/crazed/7670423 *** after you download the file (moto-fastboot-osx64), RENAME it to mfastboot.
Although the link on how to SBF back to stock shows android 4.4, it doesn't matter. The SBF process is the same no matter which version you are on. You just need to download the right carrier/version from here http://sbf.droid-developers.org/phone.php?device=0
Not to confuse you but if you were to install virtual windows, you could probably use the rsd lite method.
Do one but not both. The native (manual) version should be simpler for you. I had assumed you already had the necessary android SDK since you said you went through the whole safestrap process and everything. Were you on a different computer when you did that?
Have you received your code yet? Hold off on SBFing until you have it in hand.

Just got my code at 23hrs.
I just wanted to do add onto the process and make minor adjustments to make it clear.
Did Step 1.
and then at the end
He will say reboot, but don't go waiting to install your apps or update it or setting it up. Just start it up normal power up. Then when it says select language (not sure if needs debugging or not but I did) go to developer options by clicking on settings. go all the way down to "about phone" tap on "build number" a couple times you will see developer options pop up. Go back and go down to developer options and go find usb debugging. Then hit accept on phone pop up when usb debugging is enabled so your phone trust your computer. then do ./adb reboot bootloader
It should get you into ap fastboot mode then do my step 2.
Step 2 - Unlock bootloader before doing mfastboot-ing the twrp so you don't get the
invalid image size on your phone
or
writing 'recovery'... INFOPreflash validation failed
FAILED (remote failure) on your terminal
So by doing this to unlock bootloader
fastboot getvar all
then
fastboot oem unlock CODEHERE
Should give you a "unlock" blue text with black screen.
Then the step 2 mentioned by samwathegreat for TWRP which will download the file without the invalidity error message on both computer or moto x on ap fastboot screen.
Then step 3. I used the Down arrow to select "recovery" which gave me the TWRP screen.
Step 4. I went into the TWRP screen and hit reboot and a pop up for SuperSU popped up notifying me to install SuperSU. Swipe next and it'll install and then voila!
Step 5. Click on SuperSu app and it should reboot and try to install.
Step 6. Hit the thanks button to samwathegreat

Excellent! Thanks for pointing that the instructions didn't specify that you must unlock your BL before flashing TWRP. Edited Post # 8 to include the step. You can also unlock BL before you start any of the steps, but must do it before flashing custom recovery as you have pointed out.
I did suggest a slightly different method, however, that doesn't require enabling developer options or usb debugging. If you unplug the phone and power it off, you can get straight into fastboot mode without 'adb reboot bootloader'. You just hold down VOL DOWN, and power it on. Then you plug the USB cord back in. It only works if you unplug the phone first....for some reason if you leave it plugged in, you can't power off the phone...it just immediately reboots.
So, to wrap this all up, just a couple more questions:
Did you complete the entire process on your Mac? And can you confirm that the error you were originally receiving (in Original Post) is no longer popping up?
And finally, check out xposed framework installer and "gravity box" mod. You can do some really cool mods with gravity box. I suggest you boot into TWRP and make a nandroid backup -just in case- before you go playing around with xposed.
Have fun.

Yes I complete the whole process on the Mac. Yes the original error is no longer popping up. What is a nandroid back up? I did a back up after I installed all my apps and updated it and dragged that copy to my desktop and uploaded it to my cloud.
I hear about xposed framework and gravity box but I have no clue what it looks like and also forgot what nandroid is but I'll look it up.
And yes android reboots can't stay on shut down when cord is connected. Which is funny.

If you backed up from within custom recovery (TWRP), thats the same thing. Some recoveries call them ''backup', some 'nandroid'....same thing.
Thanks for the final follow-up. Take care...

[Q] I done screwed up big time - the mystery of the unflashable recovery

Back story: Verizon Moto X, unlocked bootloader via China Middleman, running Eclipse ROM 4.4.2, TWRP 2.7.0.0 recovery
Objective: wipe everything and flash back to a (rooted) stock for device retail
Why I'm screwed: everything is wiped - phone has no OS, recovery, etc. It simply hangs out on the Motorola M at boot and doesn't move. fastboot loads and will flash recovery (seemingly successfully) but rebooting to recovery always gets stuck at the logo
How I got there:
1. Backed up with TWRP, then flashed new recovery CWM (the one here) and backed up again. Saved both folders of nandroid backups to my PC (yay)
2. Flashed back to TWRP (but this time the new one v2.8.0.1 here, which I downloaded and flashed via that fancy new TWRP app [I selected the "ghost" model]) clicked about every type of wipe option I could get my grubby little fingers on, then adb pushed the ROM and kernel/radio combo from here.
3. Attempted to flash the new ROM via TWRP. It failed. something about an "Error executing updater binary in zip". I sighed, said "meh", googled the problem a bit and figured I'd reboot the recovery and try again. This is where things get weird.
4. Phone hangs out at boot logo (that kaleidoscope "M"). Fine, I accidentally did a normal boot, and there's no OS installed. I go into fastboot and boot to recovery. SAME SCREEN. TWRP has apparently disappeared. No matter. I go into fastboot and flash it again, then boot to recovery. SAME SCREEN. Flash back to CWM. SAME SCREEN. Back to TWRP one more time just for giggles? SAME SCREEN.
No idea where to go from here. Anyone have any idea how this happened and what my options are at this point? Is there a way to manually flash a ROM via fastboot? Restore either my CWM or TWRP nandroid backups without access to the recovery? Any guidance would be appreciated.
Attachments:
a) boot logo I'm stuck on
b) command line log of commands from flashing recoveries

From fastboot, flash your recovery and then use the volume down button to highlight recovery and then volume up button to enter into recovery.

Well I wiped my system partition when I must have been drunk or something b/c I still can't believe I did it. But I did. Then from bootloader mode, I ran the command mfastboot flash system system.img from a command shell on my PC using the system image from the sbf that my bootloader was currently on (in my case, it was 4.4.4). All was good.
Then I could restore my nandroids by moving them to my phone from my PC.

Could you elaborate a little more on this? How do I get the system.img file to flash? I'm guessing my bootloader would be on the 4.4.2 one since that was what Eclipse was on, but is there any way to check? Deleting the system partition was definitely what I did. Also, why mfastboot as opposed to just fastboot?

because the moto x system images are too large to flash with fastboot, you have to use mfastboot.

yeah he really needs to check b/c it really matters what version of the bootloader he is on.

Flashing the 4.4.2 system.img (and boot.img just for good measure) worked! I was then able to boot normally and then upgraded to 4.4.4. Oh happy day. Thanks for the help everyone.

Sorry, meant 4.4.2.

So glad!! If you are unlocked, as long as you can get into a functioning bootloader mode and have access to the sbf for your version of the OS you haven't bricked.
I about near had a heart attack when I deleted my system, but no biggie to restore it. I think I only paid $35 to unlock b/c I did it straight through tao bao, but it was the best $35 I have spent in a long time. I drop $35 every time I go for sushi, so I can't imagine not paying to unlock if you have the option.

Need help upgrading to 5.1, Tired of flashing all the things.

My nexus 6 is unlocked and is running stock 5.0.1, rooted. . It has twrp and is decrypted.
I tried to sideload the 5.1 ota but it doesnt work.
I tried flashing the new 5.1 factory image but that doesnt work.
I'm tired of all this now, I just want my phone running stock 5.1 , locked , encrypted ,unrooted so I can just get ota next time from Google whenever they send it out.
Any guidance on what I need to do would be appreciated.

Use Wug's Nexus Root Toolkit :good:
Edit : Now I'm currently "Optimising app..." loop.

I tried using tge NRT to flash it back to stock but it didn't work.

I would first make a TWRP backup, then I would flash the boot image (decrypted if you want and make sure its the new one), system, radio and then reboot. I flashed everything fine while keeping twrp on my phone but I didn't like not having a custom ROM plus it was a little laggy so I restored a TWRP backup. My phone did bootloop for a while but eventually it booted 5.1. I would be careful since 5.1 seems to be having some issues in general.

It worked for me after that. Now I'm booted in 5.1

When I try to flash the factory images directly from Google I get the following errors even though the MD5 checks out.

I agree that always works without fail and is much easier than a tool kit. I don't like tool kits because people need to learn the correct way to flash things before using one because its better to understand what you are flashing should there be an error.

I don't have anything against toolkits on some devices, so long as it is not used as a shortcut to learning the basics. That said, on a nexus, I don't really see any need to be honest.

Im a complete fastboot novice since this is my first nexus device (always had samsung phones up until now) and although I managed to root and unlock the boot loader I want to make sure I learn all the basics including flashing (side loading?) subsequent updates.
So Im currently rooted, unlocked bootloader on a 5.01. custom rom. How would I go about flashing the 5.1 update manually?
Im assuming that once I extract the update zip file I will find all the images that need to be flashed....what order do i do them in? How do I take into account the boot loader locking issue people have been facing that results in a bricked device?
Thanks in advance.
EDIT: I found this thread which outlines what I need to do http://forum.xda-developers.com/nexus-6/general/using-image-to-update-nexus-6-data-loss-t3053158
I only have two question now:
1. Im assuming the system image will wipe out the custom rom im on but not the data will leaving the data cause a problem? whats the command line to wipe data?
2. This doesnt address the boot loader locking issue causing a brick that people have been facing. This process involves updating the boot loader what do i have to do to make sure I dont brick my device?

You could simply not update the bootloader. Bare minimum requirements is update system and boot (kernel). if you want to learn more about fastboot, go to general > All in one guide > Question 28.
If you do not update the bootloader, you'll never get an OTA but it doesn't seem like you're wanting that anyway.
In regards to data, yes it could cause a problem if you're using a custom rom. You can use fastboot erase data command. This also wipes your /sdcard though.

[A2017U][TWRP System Image] Stock System Image of B20 for full stock restore and OTAs

THIS APPLIES ONLY TO THE A2017U VARIANT, DO NOT USE THIS FILE ON OTHER VERSIONS
Disclaimer - don't blame me if something goes wrong
As title says, this is a full stock unmodified B20 TWRP system image. It kan be used in addition to stock boot and recovery images to restore the US A7 to conditions which will be like stock and allow to flash upcoming OTA. This was tested by @jkuczera here http://forum.xda-developers.com/showthread.php?t=3459107

If you are BL unlocked, you will need to lock it before flashing old recovery and boot (this may not be necessary to get MR2 to flash, depending on what it checks, but the phone might not boot, unknown). This will make your phone verify boot, recovery and /system again, so flash TWRP from tenfar's thread to be able boot after relocking since his is signed
To restore, unzip the file above to TWRP folder on the SD Card, then in TWRP under mount points unmount /system and put check mark on mount system as read-only. The read-only part is important so that TWRP does not modify the /system apon exit. You can then restore boot, recovery and system image.
Another partition, fastboot, was altered if you applied B20_boot, but so far no OTA has check it so it should be fine as is. Chance is it will be just overwritten by next OTA, but in case that changes, info will be added. This step is more risky since it involves using dd command and has to be applied carefully.
EDIT: looks like @Unjustified Dev posted new build that will flash fastboot image http://forum.xda-developers.com/showpost.php?p=68677272&postcount=133
You should then boot to stock recovery and factory wipe
In case you did not dump your boot and recovery, they can be found in @rczrider's post here

Thanks to @swehes for providing the space on his cloud for this file, @rczrider for rest of the files and @jkuczera for trying this all out

So you need TWRP for this, but will this overwrite the TWRP recovery and make it truly stock?

Indeed and before rebooting , you MUST Wipe Data + Internal Storage, cuz you are flashing new boot and system and will get in conflicts if there no wipe.

Just for clarity sake these are the steps I need to take to get back to B20 from B20_Boot?
1. fastboot oem lock
2. put system image from OP's post AND stock_boot_backup.img AND stock_recovery_backup.img from rczrider's post into TWRP folder.
3. in TWRP unmount /system and check mark on mount system as read only.
4. Flash boot, recovery, and system image.
5. Wipe Data and Internal Storage.
6. Profit?

And as option 3 it's inside the B18toB20 OTA file floating somewhere around here

Alright I tried this and something went wrong.
First thing I did was copy all the files where they needed to be. Then I booted into fastboot and did a "fastboot oem lock".
Then my device would do nothing. I would boot up to the ZTE logo then go black a second later. I tried to force into recovery by selecting recovery in fastboot but same thing, ZTE logo then blackness.
I got it back by getting into fastboot and performing a "fastboot oem unlock" again. All it did was wipe data.
What did I do wrong? I thought I am supposed to lock bootloader first before I restore system and flash recover and boot????

Ok so if you modified boot, system or recovery in anyway then after BL lock it will not boot since it will fail secure boot, so you need to load the signed TWRP from tenfar's thread via EDL after locking. That will let you run TWRP with locked BL. Although ig you just want stock for upcoming OTA, then you might be good staying unlocked. If for return, then you should lock it

Yeah, now that we know fastboot will work even on stock boot that will work as well. The only thing you won't be able to do is flash back the B20 fastboot image that way, but enough to pass OTA most likely. The long way you can revert the fastboot image as well. I only wanted to post the image to begin with, but then wrote out instruction as they rolled around in my head. This will change soon anyways so a proper write-up will happen, just not by me, Documentation was never my forte

My BL is unlocked from ZTE right now, If I want to get CM for future but also want upcoming update from ZTE? What are the exact steps that I need to follow to get future OTA but also keep the BL unlocked for future CM? Please help as I'm confused with all these instructions.

If you are BL unlocked, you will need to lock it before flashing old recovery and boot (this may not be necessary to get MR2 to flash, depending on what it checks, but the phone might not boot, unknown). This will make your phone verify boot, recovery and /system again, so flash TWRP from tenfar's thread to be able boot after relocking since his is signed
To restore, unzip the file above to TWRP folder on the SD Card, then in TWRP under mount points unmount /system and put check mark on mount system as read-only. The read-only part is important so that TWRP does not modify the /system apon exit. You can then restore boot, recovery and system image.
Another partition, fastboot, was altered if you applied B20_boot, but so far no OTA has check it so it should be fine as is. Chance is it will be just overwritten by next OTA, but in case that changes, info will be added. This step is more risky since it involves using dd command and has to be applied carefully.
EDIT: looks like @Unjustified Dev posted new build that will flash fastboot image http://forum.xda-developers.com/showpost.php?p=68677272&postcount=133
You should then boot to stock recovery and factory wipe
In case you did not dump your boot and recovery, they can be found in @rczrider's post here

Thanks to @swehes for providing the space on his cloud for this file, @rczrider for rest of the files and @jkuczera for trying this all out

Can someone please explain exactly how to do this. I have an unofficial twrp on my phone and the bootloader is unlocked but after i tried to flash super su it got stuck on bootloop so I wiped every thing and I also accidentally wiped my os too. So now I don't have an os and I want to go back to stock. Can someone please explain step by step on how to fix this? I just got the phone.

All right I'm no expert either but I'll try to make this as straightforward as possible.
1) Format your SD card as exFAT. This is important as otherwise you will not be able to transfer the system image to your SD card since it is 6GB. To do this you can just plug it in to your PC, right click, Format and then select exFAT from the dropdown.
2) Download tenfar's tool for B20, rczrider's boot and recovery backup, and the system image backup from the link in the OP.
3) Create a new folder in /external_sd/TWRP/BACKUPS/serial_number/.Move the stock_boot_backup and stock_recovery backup into the folder.
4) Using a program such as 7zip, extract the 6GB system image file and move it to the same folder.
6) Go to into fastboot mode. Before you do anything you have to relock the bootloader otherwise the system will be modified and you want to be 100? stock. Execute 'fastboot oem lock'. You should then boot to a black screen.
7) Unzip tenfar's tool. Go to the unzipped folder, then hold down shift+right click and select 'Open command window here'. Execute 'axon7root.exe -p [COMPORT #] -r. To figure out your com port #, go to Device Manager, then go to down to where it says "Qualcomm Loader..." and your com port number is the number at the end. So for example if your com port number is 5, you should execute axon7root.exe -p 5 -r. Allow the program to do its thing.
5) Boot into TWRP. Do not swipe to allow modifications. Once in TWRP, go to "Install", "Install Image" at the bottom right hand corner, and then navigate to the stock_recovery_backup in the folder that you moved it to to. Select it and then choose the Recovery partition to flash it to. Do the same thing for stock_boot_backup.
6) Once you have flashed boot and recovery, go to the main menu, then "Restore" and then Restore the system image backup.
7) Go to wipe and then slide to factory reset. Finally, reboot system.
Hope that helps! If you have any questions, feel free to ask me.

Has anyone who requested the bootloader unlock from ZTE (and mistakenly installed it) returned to stock and been able to get OTA's? I followed this guide and seemed to have returned to stock fine but the only OTA I can get now is the bootloader unlock OTA. I've downloaded and discarded it several times but that is the only one I can get. Anyone know of a way to bypass this OTA and get the new MR2 that was just released? I want to get OTA's until the custom roms start flowing.
Thanks!

From what I can tell, once you apply for official bootloader unlock, your IMEI is placed on a list that will not get any future OTA updates set to it.
However, the OTA for B20 to B27 has been uploaded here: https://mega.nz/#F!kYtRAJjJ!5tD1zPpo0nw2tJwhANA9pQ
Try flashing that via stock recovery.

Quick question for anyone who might know.
The Link to system image which is : https://cloud.swehes.com/index.php/s/31V7GgihohBCdfy has the following;
1. system_image.emmc.win
2. system_image.emmc.win.md5
Am I suppose to rename system_image.emmc.win to system_image.emmc.img and load?
it's not as clear that's why I ask but I ended up downloading rczrider system.img and reflashed via TWRP since I was a bit confused.
Thanks!
***************
I simply just went into TWRP backed up by boot so it would create a directory that contains the info I needed copied the system_image.emmc.win and system_image.emmc.win.md5 and restored.

I suspected as much. I downloaded the update and tried to flash it via the stock recovery using the update for ADB option but it fails saying that the package is not a ks package. Booooo. I really wanted this MR becasue they addressed the weak cell signal which I think contributes significantly to my battery drain. Not sure if there are any alternatives to get the update installed. Not very a happy about the ceased OTA's due to the bootloader unlock. Thinking the new Nexus (or whatever they are going to call them) is looking pretty good at the moment.

Try the microSD card method instead.
First, make sure OEM Unlocking is checked in developer settings, rename the OTA to "update.zip", put on microSD, boot into stock recovery, and choose update from microSD.
