Still no OTA but you want KitKat AND keep your data?

Hello friends!
I want to share some information for the beginners here:
While there is the Nexus 4 factory image for KitKat available, there still are non known OTA urls.
But you can flash KitKat anyway AND keep your data (as long as you have an unlocked bootloader):
1. Download the factory image from here:
https://developers.google.com/android/nexus/images?hl=de#occamkrt16o
2. extract ALL the files contained into the same directory where your fastboot.exe is saved, for unpacking I recommend using 7zip
3. boot your phone into bootloader
4. type in the following commands:
fastboot flash bootloader bootloader-mako-makoz20i.img
fastboot reboot-bootloader
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.84.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot format cache
fastboot reboot
You're done, KitKat on your Nexus 4, your apps and data still available!
Note: Your phone has to be full stock!!!!
UPDATE:
I'm really sorry for the mistakes I made in this thread.
I corrected them all by now, I think.
To make it more easy for you: You can rename the radio and the bootloader files let's say to radio.img and bootloader.img. Then use the fastboot commands with these new names. So you're a bit more safe not to make spelling errors.
Once again: I am sorry and I hope nobody got stuck due to my mistakes!!!

Some errors here.

If you're making a guide, make sure you give people the correct commands (the numbers of the bootloader and radio are wrong). Not to mention there already is a guide where flashing the update without losing data is explained.

The numbers of radio & bootloader in Factory image itself are wrong

I am sorry for the two "spelling errors". I corrected them, should be all fine now.
I did not notice that the other guide contains information about flashing KitKat without losing all your data...
sometimes it can be hard to keep an eye on all the threads in every detail...

fastboot flash bootloader bootloader-mako-makoz10i.img still wrong should be 20 instead of 10

Don't really want go threw all that ..
dose somebuy just have image I can flash without having to use the above
I want down load the Image

there are some stock images with root on android develop or orig android develop.
edit: can use dd command to flash images if u have root.
do dd if=/block of/img
like dd if=/dev/block/platform/by-name/system /data/media/0/download/images/zipextracted/system.img

I thought it was excellent! Anyone who knows what they are doing in the Command Prompt/Terminal understands that they can hit the Tab key to auto-complete the filename. Its up to them to make sure they are accessing their correct folder/file name, not yours!

good work, although i have a different question, why is it that everyone always recommends 7zip for extraction of factory image, i have always been using winrar, i googled this and got nothin, so plz do tell anyone who knows the reason

In my opinion 7Zip looks slightly better and it doesn't spam you with that your trial is over every time you open it.

what to do with a custom rom?
I have PA on my N4 and was wondering what to do to get KitKat? is the procedure similar or different?
Thanks a lot!

7zip is far more friendly towards archives other than rar and zip formats. it's also the only archive app I've found that will allow you to open a flashable zip or apk and replace files inside (like an icon's image file, for example) without having to actually decompile/recompile either the zip or apk (assuming you don't change too much with either file-type)

whether it's a custom or stock rom does not matter. the procedure will be the same either way

Upgrading 4.2>4.3>4.4 was always a piece of cake with Wug toolkit and never had to reinstall any application.
Keeping my settings and applications was important for me.

how is this method different from if i just removed the -w wipe parameter?

the method you refer to will still install the userdata.img file, which will wipe your rom's userdata, as well as anything on your storage partition. The method mentioned in this thread's OP omits the userdata.img file and relies on the user manually wiping the rom data in n custom recovery, therefore wiping only rom data while leaving the storage partition untouched.

Confused as to why people take all these steps when its just unlock>flash recovery>Flash update rom of your choice and done. All these threads on the same thing makes no sense and lets be honest its not that hard to keep up with threads if you search extensively prior to making up a thread which at week three of KitKat you should of thought would be up already.
Not flaming anyone just trying to understand the thought process. Mistakes happen I get it but we got to do better especially with so many people destroying their phones over simple things.... Jus Sayin'

I updated from 4.3 to KRT16O (and later, KRT16S) by omitting the "-w" from the batch file, and I didn't lose a byte of userdata. My bootloader is unlocked, but everything else is stock.
It was so painless, I wonder why I ever bothered waiting for OTAs in the first place.

[Q] How can I reinstall a good image after flashing my boot with CWM?

My question is similar to 'nikpmr's troubles but different enough I think they deserve a separate post.
The Problem as Understood​I was trying to root my device following the guide at this website. It's so simple it's a wonder I messed up. I think my failure was that I thought the drivers installed when I connected the phone were enough so I skipped that step. Then when running fastboot flash recovery.img the install failed. So I saw on some forum that it was supposed to be fastboot flash boot recovery.img of course now I know if anything it ought to have been "recovery" not "boot".
What I've Tried & Partial Solution​At first I was just stuck in a boot loop and selecting "sideload" from the CWM recovery failed to allow me to connect with ADB or fastboot. i.e. Running "fastboot devices" and "adb devices" both returned as having no devices connected to my computer. So I installed the HTC Sync and promptly uninstalled the non driver parts of the app. Then I installed USBdeview and used it to uninstall all the USB devices associated with my HTC First. After doing that I learned booting into HBOOT allowed me to connect to the computer using fastboot and after then booting to the CWM Recovery I was able to connect using ADB to do a sideload. So I guess I'm about halfway there. Unfortunately after looking up the newest RUU and attempting to sideload it using "adb sideload OTA_MYST_UL_1.08.502.1-1.08.502.4.zip" the sideload failed. After selecting "- install zip from sideload" I get a message twice of "failed to open driver control: No such file or directory". It also failed when I attempted it with a similar fastboot command. So from all that I surmise my ROM is ruined and just needs to be replaced.
Question​So how do I go about replacing this ROM and boot partition? And, which ROM should I use? Is the one I got from the RUU site suitable? And what about the radio? I just need my phone to work. I can worry about rooting later. At this point I think I know what's happened but I don't know where to begin reading to figure out how to fix it myself.
Thanks for reading,

1. you had to type in fastboot flash recovery recovery.img NOT fastboot flash boot recovery.img

Well there was an actual all in 1 tool to get cwm/twrp & root with a click for this specific device somewhere around these threads.
1) what exactly is the problem? (Sorry it was just so many words)
I don't think side loading the RUU would work bc I haven't heard its possible to flash it in the phone itself.
2) why don't you just sideload an existing pre-rooted ROM instead of the RUU file?
3) I see you're s-on, did you try flashing just the boot.IMG from the ROM you've got on it?
BTW I've only had luck with twrp on having it successfully detected when wanting to sideload

1) The issue is I did "fastboot flash boot recovery.img" rather than "fastboot flash recovery.img" now I don't seem to have a boot mount point.
2) That sounds best. I didn't realize the RUU want a flashable ROM. More I just have to find the updated stable stock ROM.
3) I didn't have a ROM on it. I was just trying to root stock. Seems like I'm pretty close once I find that ROM.
Thanks y'all! Between your answers I think I have enough to go on. Feel free to point me to your preferred stable ROM. I'm content with stock but it would be nice to have Tiranium BU.

Thanks guys I know I always like to know when something I said was successful in helping someone. I just wanted yall to know after sideloading the most recent Odexed ROM then pushing it to memory after it wouldn't boot I succeeded after taking abrahammmmmm's advice of flashing the boot.img from HBOOT. After a longer boot than I'm used to I was able to get into my phone again. I wasn't able to use my TitaniumBU to restore but that just meant I had to spend a few minutes selecting apps to install.. And restoring a data backup for the only important app that doesn't keep the primary data off the phone.
Thanks again!
tl;dr Flashing the Odexed ROM boot.img fixed my issues. Thx!

i think what happened, when you typed in "fastboot flash boot recovery.img" is this
boot, is also known as kernel in aosp and rom building terms, because if you look inside a rom.zip, you will see that the kernel is the boot.img
so what happened is you flashed a recovery as kernel, and duh it wont boot cause if the kernel doesnt work, the os doesnt either
so what YOU did is you simply reflashed the stock kernel, usually after changing a kernel, it takes a while to boot cause...well you get it right?
the kernel is what android is based off of, kind of like ubuntu, its a linux os based on the original linux kernel.

That's what I thought happened. If I had stopped to read the help on fastboot before running "fastboot flash boot recovery.img" I wouldn't have made that mistake because I would have seen I wanted to flash recovery. One thing I *did not* know, which I'm glad to know, was that the boot.img contains the kernal. I was thinking Android was more similar to IBM style PCs than it is and therefore the boot.img was analogous to a bootloader like grub or lilo.
So the one thing I don't get is how is partitioning done? I take it Androids have some reserved partition for boot and the boot.img takes care of all system partitioning and mounts /sdcard/ for everything else. i.e. userland; appdata, media, and files. Am I guessing correctly?

in a nutshell yes, the boot.img uses the fstab

Yep that's correct.
The name correlation is booting up requires kernel there for kernel is called beet.IMG
Thing about custom kernels, they aren't like that and simply contain modded files and pretty much an in packaged kernel.

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.

3. Click "Flash stock plus unroot"
4. Check all the boxes under "Settings", including "Post-flash factory reset" then click OK.
5. Follow the toolkit instructions from there.
This got me out of the bootloop, successfully installed 5.1, and kept all my apps and settings. Good luck.

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.

Thats how I feel because its so easy my wife could do it and she doesn't know anything about flashing. Toolkits are good for non Nexus devices, I just don't see a point when we need to learn things the correct way first.

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?
Thanks again

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.

[MoFo IMG] 5.1 Rooted AT&T XT1097 with Tether

Below are the instructions for using MoFo to flash the AT&T XT1097 to 5.1. The rooted image has a modified build.prop file for free tether. Thanks go to @Slack3r for making the ext4 image and @btdownloads7 for developing the root method.
Since this is a 5.1 image, in order to get it to boot, you need to do the following BEFORE flashing the 5.1 system image:
1) Download the stock 5.1 files and extract them:

2) Using a root file explorer (like ES Explorer with root enabled), delete everything in /data/dalvik-cache and /cache - YOU MUST DO THIS!
3) Reboot into bootloader mode and run the commands below to flash the following stock 5.1 files for the XT1097:
Code:
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot flash recovery recovery.img
Do NOT flash the 5.1 bootloader (motoboot.img) or partition table (gpt.bin) - if you do, you will not be able to use MoFo ever again!!!!!
4) Download the rooted 5.1 image from here, extract it and flash it using MoFo.
https://mega.co.nz/#!ct8DlQxQ!DRMC_TvCcUk7V-FjCBfjsmIoOvw_f0WEdM7gx2waqzM
MD5 of the unzipped file = 146B6A65D925B985857A2F28D4294765
Note that with the XT1096 we had issues if we tried to boot into recovery after initially flashing the 5.1 system image so instead of booting into recovery and wiping cache where you might get weird flashing dead androids, we had to boot into system first.
Obviously if you want Xposed or anything else in the image, someone will need to add it in.

Thank you!
Those of us already rooted with mofo on 5.0.2 need to return to stock 5.0.2 first, correct?

No, the instructions as written in the OP are complete. Like the instructions say, you need to do step 2:
2) Using a root file explorer (like ES Explorer with root enabled), delete everything in /data/dalvik-cache and /data/cache - YOU MUST DO THIS!
Then you can flash the rest of the 5.1 stock files for your device EXCEPT for the bootloader (motoboot.img) and partition table (gpt.bin). Then use MoFo to flash the rooted 5.1 image for your device.

Thanks for clarifying.
I followed the instructions precisely, and the phone won't power up normally. It goes into recovery, and the android icon with exclamation just flashes intermittently. I'm unable to enter options to wipe cache. I can boot into recovery by holding volume down, but normal startup presents this behavior.
Any ideas?
EDIT: I chose BP Tools in boot options, and now the phone at least appears to be booting normally -- currently optimizing apps.
EDIT 2: Okay, so selecting BP tools evidently kicked the phone into booting normally. Looks like everything is just as it should be. Not sure what happened here, but in the end everything is good. Thank you (everyone involved) for getting this done for us!

This was happening with the XT1096 - you have to get it into system before recovery. You likely hit the wrong button and ended up in recovery instead of system. But once you get it into system, then it is fine.

Thanks again @JulesJam I am downloading now! Do you notice a big performance difference in 5.1? Will be nice to finally kill these memory bugs, so major thanks for that!

The OS is much snappier than 5.0.2. You can tell by going into multitasking and seeing how quickly the tiles load. Very, very nice. No re-draws at all yet since I flashed.

Step 2 implies that I'm already rooted. If I'm not, I assume I need to start with Step 0: Root the device with a 5.0 IMG?

What all would I need to fastboot flash from the stock files to return to stock @JulesJam ? My company just started using AirWatch service to get company email. Problem is airwatch will not work with root. Unfortunatly I will have to lose the ability to use MoFo.. Any help with this is greatly appreciated. Thanks!

FYI - like it says in the MoFo Noob Guide - MoFo trips the root checker and it is not able to be undone by flashing back to stock. I don't know how AirWatch works, but if it looks at the qe, then it will see you as rooted even if you aren't.
First thing I would do is flash back to 5.0.2 by flashing the stock 5.0.2 firware (link is in the MoFo Noob Guide)
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk1 (repeat this for all of the sparsechunks)
then boot into recovery and wipe the cache. Then boot into system. I believe it will need to downgrade the sensor firmware so allow that to happen.
Then boot into bootloader mode and see if your software status still says modified or not. Then boot into recovery and see what your qe status is. If after that your software status is still modified and your qe is still 1/1, I would do a factory reset and see if that corrects it. It probably won't though.
You will then have to decide whether or not you want to take the 5.1 OTA because your phone is going to want to upgrade. Instead of taking the 5.1 OTA which will upgrade your bootloader and partition table, you have the option of flashing stock 5.1 everything but the motoboot.img and gpt.bin. That would keep you stock 5.1 but still keep your bootloader and partition table on 5.0.2 so that if you wanted to sell the phone later, you could sell it with a copy of MoFo that still works. I put this out there because idk how AirWatch works and if flashing back to stock doesn't change your software status from modified or your qe from 1/1, you may not be able to use AirWatch, idk.

Thank you so much for the detailed explanation @JulesJam . Unfortunately I followed the instructions to the T and didn't run into any issues until I tried to boot into recovery. I got the dead android with a line under saying "no command". So I tried running system first. I got through the boot animation and then a black screen. I let the black screen sit for 30 min and nothing happened. I had the exact issue when installing 5.1, I was able to get it to boot using BT tools. Unfortunately this is not working now. I get the same black screen after the boot animation. I tried multiple times with no luck. I can however still get into fastboot without issues
Any ideas how I can get 5.0.2 to boot? Thanks again!

For sure you flashed the 5.0.2 logo.bin, boot.img and all of the 5.0.2 system sparsechunks? That sounds like the system partition was not flashed properly.
Perhaps the 5.0.2 system files you have are corrupted? Are you sure the files you have are the stock 5.0.2 files for the AT&T XT1097?

That's OK as long as he is not flashing. When you have the dead android, go ahead and press and hold power then tap volume up to get into recovery and wipe the cache.

Thank you! I was able to get into recovery to wipe cache, but still won't boot.
I downloaded 5.0.2 from your noob guide, and flashed everything in the order of your first replied post. I am going to start over, just in case I missed something.
Don't think it matters but the sparsechunk starts at 0 in the AT&T file. I flashed the sparschunks in order, and in my case 0-8.

How long do you let the blank screen sit before you try to get into bootloader mode? I remember sometimes it takes awhile for it to boot.
Also, the dalvik-cache may need to be wiped too. That would require a factory reset to do it so you could boot into recovery and do a factory reset. Unless there is some way to wipe the dalvik-cache from bootloader mode.

And after you do, let it sit at the blank screen for awhile to make sure that it isn't an issue of needing time to boot up. If it still won't boot, try the factory reset.

Thank you so much @JulesJam !!! I'm booted to stock 5.0.2 now. I did have to do a factory reset, but not too big of a deal. Unfortunately I forgot to backup my 48 tasker profiles...lol. So glad to have it back up. Thank you again!!!

Glad it worked out, sucks about the tasker profiles though. So it seems like the dalvik-cache has to be wiped, too. I will note that in the future people should delete the contents of the dalvik-cache folder before flashing back to the earlier version of the software.
Does your software status still say modified in bootloader mode? What is your qe when you boot into recovery?

[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

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?

Pretty much. I would reboot to stock recovery after and factory wipe from there. you might wan't to flash fastboot from B20 OTA for extra profit but seems like it's a moot point so far if you have seen the Unjustified Devs trick for BL unlock via TWRP

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

I apologize if I am fundamentaly not understanding this but wouldn't it be easier to flash system, boot, recovery, and fastboot back to stock via my current twrp THEN relock bootloader?

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.

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.
