[GUIDE] How to root your ZTE Android device

This method doesn't rely on any root exploits & will work with any Android version on the ZTE Blade (and all variants). It should work on any phone with an unlocked bootloader (all zte android devices are sold with unlocked bootloaders).
Software needed:
adb (windows/linux/mac versions available as part of the android sdk - http://developer.android.com/sdk/index.html You will find adb in the tools directory.)
fastboot (windows/linux/mac versions available here: http://koushikdutta.blurryfox.com/G1/ )
windows drivers for the phone (if you use windows: http://support.zte.com.cn/support/news/NewsDetail.aspx?newsId=1000442 )
ClockworkMod (http://clockworkmod.com/rommanager - download zte blade clockwork recovery image)
SuperUser ( http://androidsu.com/superuser/ Download Eclair/Froyo/Gingerbread/Honeycomb (2.1 – 3.2) version) - Alternatively you can use any rooted custom rom
If your phone is running Android 2.1, then it is probably a 'gen1' device, search for "Mr Pigfish" on Android market if you're unsure. Gen1 blades will need an older version of clockworkmod, 3.0.1.4 - http://download.clockworkmod.com/recoveries/recovery-clockwork-3.0.1.4-blade.img
Method:
Download/install adb & fastboot. Install drivers for the phone if needed (on Windows).
Plug your phone into your pc using the usb cable, mount usb storage, then copy the Superuser or custom rom zip onto it & unmount usb storage.
Make sure that usb debugging is enabled on your phone, there should be an icon in the status bar, you can enable it in settings (settings -> applications -> development -> usb debugging).
Open a command terminal window & change to the directory that you downloaded recovery-clockwork-[version]-blade.img to. Type...
Code:
adb reboot bootloader
This will make the phone reboot, wait for the android logo (or custom splash screen) on the phone then type...
Code:
fastboot flash recovery recovery-clockwork-5.0.2.0-blade.img
fastboot reboot
You have just installed ClockworkMod recovery. Your phone will reboot back into android, when it has done that turn it off, then turn it on with the vol- button held to start clockworkmod. Use vol+/- to navigate, home button to select an option, back button to go back. You should create a backup now before you flash anything, when that backup is complete use 'install zip from sdcard' to either install superuser to root your stock rom, or install a custom rom. If you're installing a custom rom then you'll need to wipe data/factory reset too (you will lose all data). reboot, you're done.

I'm not sure if this is the right section for the thread, it'd probably be better in blade general. I forgot that newbies can't reply here.
Anyway, for those that can reply, can you suggest any improvements? I'll find links for adb, fastboot & windows drivers later.

Everything is clear except where to find adb and fastboot for noob users... (like me).
I did a little search and found out that adb is installed with the Android SDK... so, i installed it, installed the android platform-tools package, the usb driver but i am stuck with fastboot...
There is no fastboot in the Android SDK installation directory... and i can't find it on the web... so, i can't install clockworkmod recovery and i'm stuck...
Can u help me plz ?

Yeah, as I said, I'm still looking for links. you get fastboot when you compile android from source, but that is a bit of a long & complicated way.
Here is a pre-compiled version of fastboot for windows, linux & macos http://koushikdutta.blurryfox.com/G1/
adb works without the sdk too, I'll see if I can find links for that.
The windows driver is on zte's site somewhere, but that's a pain to find anything on. I'm not sure if the Google driver works. I don't even run windows, so if anybody can help write that part...

Probably best to for XP use the exe driver installer (Thats in the pcsuite.iso in the official 2.3.5 rom)
Windows 7 just works (gets drivers from windows update).
Does the superboot apk deal with changing default.prop (to allow adb remount etc).
If not could do that (use the same thing the CM7 universal converter uses to split the boot.img).

Not everybody is running the official 2.3.5 rom, it's probably a tiny fraction of users. 2.1 roms don't have the driver iso. I found the drivers & updated the first post. The drivers on the phone should work fine, if you are running an unmodified 2.2 or 2.3 stock rom, just plug the phone in & it should mount a driver cd image over usb to install the drivers.
Does the superboot apk deal with changing default.prop (to allow adb remount etc).

It's superuser, it's a clockworkmod zip file & no, it doesn't change default.prop. It installs superuser & su.
If not could do that (use the same thing the CM7 universal converter uses to split the boot.img).

Hi wbaw....
nice to see you posting helpful stuff here....
Can I ask what is perhaps a silly question, about the rooting process for ZTE devices, without relying on root exploits?
How is this different, or better, than using the z4Root modified by kallt_kaffe App, which I have linked (MoDaCo).
Is it just the use of the exploit, or is there another reason?
I have used it on my OSF/Blade, and never lost root or had any other problem, AFAIK.
Also, I see you are not showing your previous GEN1/Gen2 all-in-one TPT for GSF any more...is it available any more for ppl who may want to try it?
Thanks in advance

The exploit that z4root uses doesn't work on newer versions of Android (2.2.2 & above), ZTE are selling some phones with these newer versions of Android.
If z4root works for you, then that's fine, there's nothing wrong with it. It just doesn't work for everybody.
If you are using a version of Android that z4root (or other root exploits) do work on, then you should update Android asap. Otherwise a malicious app could use the same exploit to take over your phone. Root exploits themselves aren't bad (as long as you're doing it to your own device, or with permission of the owner) - the fact that root exploits work is bad & a sign that you need to update the software asap.
GSF has it's own thread. You can get the same effect by using the gen1 to gen2 tpt & then installing gsf. It is buggy & old, I think there is a nasty remote root exploit out there for 2.3.4 too. Just use CyanogenMod, it's much better, less buggy, more secure, they keep up with the latest Android fixes & it has more customisation options.

Thank you for the explanation...I will go ahead and do what you have advised.
I am just continuing to use good old Swedish Spring RLS5, which I think was kallt_kaffe (Cold Coffee) also......GEN 2 thanks to your Gen 1>Gen 2 TPT.
I think t is 2.2.
If I want to proceed to permanently root as you describe, should I use z4root to unroot first?
I will probably move to CyanogenMod, so I should use your exploit-free root instructions first.
BTW, I will be sad to move on from SS, as it does seem to be as near a perfect fit as I have found for the Blade.
I did put on GSF ,some time ago, and to be very honest, I just lasted a night with it, then restored the SS Nandroid.......it didn't feel at all as satisfactory a UI experience as SS.
Perhaps it was me, you know, you get used to an old pair of sneakers, etc.
As you said, it was and is always beta...it was an early version!!!
Thanks again, and keep up the good work in these calm(er) waters

Custom roms are already rooted. You don't need to root a custom rom, you just install it with clockworkmod.
If you already have a custom rom installed then you don't need any of this guide, you've already got clockworkmod. All this guide does is tell you how to install clockworkmod.
This is for people with phones on a stock rom who want to be able to install clockworkmod to root their stock rom or install a custom rom.
You shouldn't still be using Android 2.2 because the root exploit in z4root works on it, therefore other more malicious apps could use a similar exploit without asking you first.

Hi..... does this work on any Android phone?
I have in mind the new Samsung W i 8150.
Getting one for Xmas.... AFAIK

It should work on some other android phones, but they'll need adb & an unlocked bootloader, so it wont work with every phone. It should work on any ZTE android phone or tablet (except maybe the tureis?).

You need to download clockwork recovery & be in the directory that you downloaded it to, to run that command.

Thank you!It works. Now, can I put Cyanogenmod 7.1 on 2.3.5 OS with this root and clocworckmod ?

You can put clockworkmod on, but cm7 might not work without a bit of fixing, it is designed for 2.2 blades, zte's 2.3.5 has a different radio firmware.
Is this a 2.3.5 blade? where did you buy it?

Well, first time i had 2.1 update-1.After that I updated the version to 2.2 Boygues (or something like this) and then i found on this forum the official image.bin (2.3.5) and I decided to update.But now, i want to try CM.

I see, you'll need to use another image.bin to go back to 'gen2' - the zte froyo radio firmware. Otherwise you wont get any phone signal, 3g or gps on CM7 because the 2.3.5 image.bin that you installed contained new radio firmware.
You don't need to root it first, you can install clockworkmod with a gen2 radio firmware using a custom image.bin like this one that http://www.mediafire.com/?jb4crw3em2m4r4x Amphoras made.
The 2.3.5 image.bin contained another new version of the radio firmware, which isn't compatible with CM7.

Uhuuu, it works.Thank you a lot! CM7.1 is awsome.This forum is awsome.

Hey I cant acess adb after doing adb reboot bootloader. When I come to the chinese letter I cant do nothing. So i cant fastboot flash recovery recovery-xxx.img.

Any guide that shows you how to root + install CWM + Tiamat rom but replace tiamat rom with ICS!

Hey, it's pretty difficult to navigate all the threads and guides sometimes, I'm a new to XDA as well.
This thread should help you out, there's a breakdown below from me as well
If anything below is wrong, could someone correct me - my Xoom arrives today and below is what I understand the process to be from my reading ...
http://forum.xda-developers.com/showthread.php?t=1249798
1. Install Motorola USB drivers, Java SDK and Android SDK tools (for adb and fastboot)
3. Unlock the device or "bootloader") allows the flashing or replacement of recovery and boot images
4. Install a modified recovery image (ClockWorkMod recovery for Android). This is known as CWM and is an app that allows you to easily flash new ROMS and Kernals etc to the device.
5. Root the device (Allow r/w access to the device filesystem)
6. Do Nandroid (full backup) with CWM (Optional)
7. Party on and Flash new ROMS / Kernals etc!
====
You can restore your device to Stock by downloading a stock image for your Xoom model and flashing via Fastboot...

Noobs guide to root MZ604 GED 4.1.2

Ok so I am in the process of doing this myself. I'm kind of doing this off my own back as I cannot get the AIO tools etc. to work, but there is a nice way of gaining root on 4.1.2. This is on a UK bought Xoom, but it is a MZ604 that has been added to the Google Experience Device program.
Disclaimer: This should be obvious by now in these threads, but I, nor anyone else who's work is involved in this are NOT responsible for anything that happens to your Xoom. By following this guide you are accepting this as fact. All that being said, good luck!
So, assuming you have an unlocked bootloader and with your xoom connected to a PC running Windows do the following:
1) Download the root zip attached (thanks to matt4321 for sharing solarnz zip in the original thread: http://forum.xda-developers.com/showthread.php?t=1965330 )
2) Download the latest version with install scripts from here and extract the windows file to your desktop: http://forum.xda-developers.com/showthread.php?t=1782235 (I'm assuming you can use any recovery image with the installer, however with this at least its all in one and ready to go. I used 2.3.2.3)
3) Put the "Xoom-Universal-Root_modded_4_JB.zip" onto the external SD Card (MAKE SURE IT IS A .ZIP, do NOT extract)
4) Run the RUNME file inside the windows folder on your desktop
5) Use option 2 to boot into fastboot
6) Once fastboot is loaded use option 1 in the prompt
7) This will then install the recovery.
8) Power + volume up to reboot
9) Do not let the device boot into android, it will get rid of the new recovery menu, hold power (on the Motorola dual core splash) and get the device to turn off before android starts loading.
10) Once the Xoom is off, start it again, pressing the volume down key rapidly until you see some options at the top, select recovery, press volume up.
11) Welcome to your new recovery! So, we need to install the root update. So select install zip.
12) Choose the root zip, go through the options and install it.
13) Reboot your device
14) Check for SuperSU
Congratulations, you should now have root on your 4.1.2 GED'ed Xoom MZ604.
Hope this helps someone, as I've been stuck doing this for a few hours now and just figured it out by reading countless threads about this.

Worked for me after I sorted out the Motorola drivers on my PC so that the adb driver worked properly.
Good work

Flash your favorite rom
Tada you will have awesome rooted xoom

Thank you, that is a nice and easy guide.

[Complete Guide] SHIELD Tablet K1 Root, Custom Rom and Xposed Framework

Hello Guys,
At first a little background story:
I bought the Tablet 3 Month ago. I have got the Update to Android 6.0 in January and unfortunately, I applied it.
So If you don't want to apply a custom rom do not update to 6.0, because 5.1.1 is much better.
I am not responsible if anything goes wrong.
Ok, so let's get started:
At first you must install Minimal ADB and Fastboot on your PC/Laptop/Mac.
Windows: https://forum.xda-developers.com/showthread.php?t=2588979
Linux/Mac: http://rootmygalaxy.net/install-adb-and-fastboot-on-mac-or-linux/
Here is the link for all OSs: http://lifehacker.com/the-easiest-way-to-install-androids-adb-and-fastboot-to-1586992378
Before you can Root or flash a Custom Rom you must flash the recovery:
You will need:
-Nvidia Family Drivers(Extract it in a folder of your choice): http://nvidiashieldzone.com/files/shieldtv/shieldfamilydriver.zip not working anymore, official link:
http://developer.download.nvidia.com/mobile/shield/SHIELD_Family_WHQL_USB_driver_201801.zip
-As many of you are experiencing problems with my previously mentioned TWRP 2.8.7.3 version I am replacing the link with the official TWRP Shield Tablet Download Site. Just take the newest stable version: https://dl.twrp.me/shieldtablet/ (Put the file into the ADB+Fastboot Folder)
-TWRP 2.8.7.3 Recovery(Put the file into the ADB+Fastboot Folder): Download URL: https://www.androidfilehost.com/?fid=24269982087009777

Connect your Tablet to your PC
Windows:
Open your Device Manager
If there Is a device with a yellow ! klick on it and update the Drivers Manually(select the Folder where you extracted the Family Divers)
Linux:
You don't need any drivers
(For every fastboot command in ADB+Fastboot you will need a "sudo" in front of it...)
Mac:
You also don't need any drivers
(For every fastboot command in ADB+Fastboot you will need a "./" in front of it...)
Flash Recovery
1. Open Minimal ADB and Fastboot
2. Type in
Code:

Please Leave a post if you are getting errors or something isn't clearly explained! And if I could help you, consider giving me a Thanks
Troubleshoot
If you are stuck in a Bootloop:
Without data loss(e.g. when you installed Xposed framework zip and its stuck in a bootloop)
1. flash the stock rom boot image BUT ONLY IF YOU DONT USE A CUSTOM ROM (it will probably loose root). go to https://developer.nvidia.com/gameworksdownload#?search=SHIELD Tablet K1&tx=$additional,shield and download the latest NVIDIA SHIELD Tablet K1 Recovery OS Image
2. Unpack the zip file and flash it to your Tablet
Code:
fastboot flash boot boot.img
If something went wrong while flashing a custom rom (after that you will need to flash the custom/stock rom again)
wipe the /data partition. It could be encrypted from the previous rom. Be aware that you need to reinstall the rom, therefore loose all your data. Troubleshot guide by agentbob123

Credits:
@xsquid mac support
@agentbob123 suggestion to mention to wipe the /data partition as a solution for being stuck in a bootloop
@champs777 suggested the newest TWRP
@grävling mentioned importance of waiting until the recovery flash is finished

My tablet just keeps rebooting to the lock screen whenever I try to go to recovery mode... Somehow twrp doesn't stick... It did when I was on Lollipop. I have already tried to flash the recovery, do a full reboot before trying to get in twrp but without success.

On mac
You dont need any drivers
(For every fastboot command in ADB+Fastboot you will need a ./ in front of it...)
example being ./fastboot oem unlock

Try other TWRP versions like 2.8.7.0 or 2.8.7.1 i think the 3.0.0.0 is for Andoid 6.0 devices so if you are currently in the newest version of the Android OS try this one out
The 3.0 versionof TWRP was unstabel on my device so you should flash it wipe the storage and flash one of the older ones

How can I remove this file without root ?

Try your normal command line for flashing recovery except change flash to boot. It doesn't flash it, just boots to it.
In other words, if you are using:
1. Fastboot Flash recovery recoveryname.img
Do instead:
2. Fastboot boot recovery recoveryname.img
While in recovery (make sure the supersu zip is on the sd card or wherever you normally flash files from first) flash supersu. You should now be rooted but without a recovery.
Go then to delete the file and then reboot, flash the recovery as normal (#1), reboot and then it should be good to go. It was for me.

rooted device no need to unlock bootloader it will unlock for ittself
just go to playstore and dowload twrp manager
choose the name of your device
and choose one of the two versions available
for shield tablet the version 3.0.0.0 doesnt work well it spilts the screen but wthe other version Works great
the link is twrpmanager on play.google
this way you dont need to connect your tablet to your pc

Great work!

Thank you for the awesome guide. Besides deleting the TegraOTA apk, is there any other app/service that I should disable to prevent OTA updates?

Followed the guide after screwing my device up with official firmware. Thanks for nothing Nvidia, why are you offering OTA that cause the device to stop working correctly.
Nothing happened other than appearing to boot itself to the "powered by android" (kernel) screen over and over.
Held down power + volume UP ...
And it factory reset itself.
Somehow.
Did I mention that Nvidia is a terrible company?
Edit: Fixed using TWRP v3.0.0 - this guide should be updated to reflect this particuarly as people who screw their device up after trusting Nvidia OTA MM will be using it.

I'm sorry that you had that problem but this guide is a general guide and not an screw nvidia (besides they are awesom giving us a really good tablet for 200 Buck, but jea?) guide. TWRP v3.0.0 has his bugs so generally when you have finished deleting the stock rom you should flash TWRP 2.8.7.3 works the most stabel.

Add TWRP to M image (Shield 1.1)
Folks,
Just received Nvidia Shield K1 and OTA immediately upgraded it to M (Shield 1.1) and I unlocked bootloader no problem. However when I go to flash or temp boot twrp 2.x or 3.x it flashes OK, but when I reboot (either via fastboot or hard off/start to recovery manually) it appears it is overwriting the recovery partition and it just boots normally.
Is there a limitation to flashing twrp bootloader in M, and do I have to downgrade to L to flash recovery partition?
I seem to be happy w/ stock (limited stick time), I just want to root at this point and install my favs. Once I get this running will supersu pro preserve root, or do I need to turn off nvidia OTA process.
Also I see optimization for chrome, does this do anything X1 optimizations)?
Thanks

After you flash twrp reboot to recovery. I may be wrong, but I think the stock ROM overwrites the custom recovery at reboot. If you reboot to twrp first after flash, twrp will disable this.

Rooting
Hi everyone,
Yesterday got my new Nvidia Shield Tegra K1 and upon using it I noticed it's a great tablet for it's price range and will do my job easier while flying my Phantom 4. To be honest it's seems very stable and solid but was thinking about rooting it. I have some questions regarding the process wince I haven't rooted anything since my HTC Fire, log time ago that was. What are the benefits of rooting this device ? Will I still be able to update the Shield with its official updates ? Will I be able to roll back to an unrooted tablet should I need too ? I wasn't planning on flashing a custom rom but if I'll do what are the pros and cons of doing so ? I know that maybe searching this forum I would find all the answers needed but since there is so much information and threads I'm lost as from were to start from.
Would be nice to guide me about how to properly root my device with all the necessary links. My tab is running on Android 6.0.
I thank you so much guys for the hard work you all do in providing such information. I know it takes a lot of time and patience.

I just got a Shield K1. I like it a lot but I wanted to root it. Then I saw how confusing it is to distinguish between it and the previous model. My guess is whatever is out there that says Shield Tablet means the old one not the K1. I also updated mine to MM cause I'm using and 128GB micro sd card for internal storage. I guess I'll just have to wait until more support comes out for this tablet such as a stable TWRP 3.0 Recovery and the ability to gain root access and custom ROMs like CM 13.

do you recommed to install all OTAs before install custom recovery and custom roms or is it better to install twrp-2.8.7.1 out of the box and then go for the custom stuff ?

I would install all updates to get the latest bootloader. Do not install twrp 2.8.7.1. Install the official 3.0.x from the official site.

Boot loop even after stock recovery! My bacon is cooked!

Okay boys Just got this phone like a week ago. Used it to replace my Samsung that was acting up. Convinced my wife I needed it and then proceeded to toy with it.
I unlocked the bootloader, flashed custom recovery (TWRP latest), and rooted (Magisk latest) to stick recovery. I was running full stock 8.1.0 no custom ROM yet I was doing reading before I wan
ted to flash. Got to feeling comfortable so I got everything ready files downloaded USB hooked up and decided to be safe and make one more back up.
So thats what I did, I made a full TWRP backup, every single partition onto an external USB. So I am safe, right? Best to be safe... But that's when I rebooted from TWRP it boot looped.
So now I am currently stuck at boot. I get the warning screen about the unlocked bootloader then "Google" logo boot screen then a black screen and back to the start again. I knew that wasn't right, so I booted into fastboot with Power + Volume Down, cycled to recovery and selected it then... boot loop. No recovery. Hmmm... That's not good. But keep calm... did some research and found a few things. So i did this...

FAQ can be found in post #3!
[SIZE=+1]10. How To Flash The Factory Images (And Return To Stock)[/SIZE]
Prerequisites: unlocked bootloader (section 1).
This section will explain how to return the phone to be like it was when it came out of the box. This will wipe everything from the phone. If you wish to flash the factory images without wiping your personal data from the internal storage please move on to the next section.
Go to Settings/Backup & Reset and perform a factory data reset. This will remove all of your user data from the device (apps, settings, photos, music, etc).
Download the appropriate factory images for your model here.
Unzip the angler-xxxxxx-factory-xxxxxxxx (x's replace variables) into a directory on your PC (for this guide we'll use C:\angler\).
Once unzipped you should have a folder named angler-xxxxxx (x's replace variables). Open it and move the following files to a new directory named C:\angler\images\:
bootloader-angler-angler-xx.xx.img
radio-angler-angler-xx.xx.img
(Please note that radio and bootloader naming changes from build to build so the filenames and below commands will change with them)
Within C:\angler\angler-xxxxxx\ you'll see another zip archive named image-angler-xxxxxx, unzip the contents of that zip into the C:\angler\images\ folder we created before. Now within C:\angler\images\ you should have the following files:
android-info.txt
boot.img
bootloader-angler-angler-xx.xx.img
cache.img (not present on Android 7.1.2 and above)
radio-angler-angler-xx.xx.img
recovery.img
system.img
userdata.img
vendor.img
Boot into the bootloader and connect your phone to your PC via usb cable.
Open a command prompt from within your fastboot folder (navigate to where you have fastboot.exe located on your PC, shift + right click anywhere within that folder, select open command prompt here), enter these commands to flash:
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash cache C:\angler\images\cache.img
(above command is unnecessary on Android 7.1.2 and above)
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
On 7.1.2 and above you'll also need to boot into TWRP recovery and wipe cache and dalvik cache.
If you wish to you can also relock the bootloader with this command:
Code:
fastboot flashing lock
(This command will wipe all user data from the device)
Important: do not lock the bootloader unless you have first flashed the stock images. Locking the bootloader while you have a custom recovery installed can result in a brick. Please also note that the locking procedure will wipe all user data from the device.
Once all operations are complete you can reboot the device.

and that didnt work either so next I tried this

Like other curious 6P users, I flashed the "full ota" zip to check out Nougat. Then I tried to restore my nandroid for Dirty Unicorns, and apparently TWRP 3.0.2-1 had a fatal flaw that borked the EFS backup. I tried literally everything I could think of, until I saw the process @be_vigilant did to revive his phone. I'm going to be using his process as the base for the guide, as well as linking you to my nandroid that has now helped two other people revive their device.
What you need:
*MMB29P factory image (although MTC20F also worked for someone).
Direct download link: https://dl.google.com/dl/android/aosp/angler-mmb29m-factory-616cf265.zip
*My nandroid backup (its stock MMB29P, decrypted and rooted)
https://www.androidfilehost.com/?fid=24686679545612465
*TWRP recovery image (3.0.2-0 or one of the newer builds that fixed the EFS stuff)
https://dl.twrp.me/angler/
*Android SDK or at least platform-tools (for fastboot, adb, etc)
The Process:
1. Extract the factory image into the location where you have fastboot.exe (mine is C:\Android\sdk\platform-tools)
2. Extract the nandroid backup - doesn't matter where, I'll explain later
3. Make sure you are in bootloader mode, and run flash-all.bat from the factory image
4. Flash TWRP (fastboot flash recovery twrprecovery.img)
5. Boot into TWRP, and make a new nandroid backup. This step is just to create the TWRP backup folder on your device
6. Now go to wipe, advanced wipe, click on each partition one at a time, choose "Repair or Change File System", then select "Repair File System" - do this for dalvik/art, system, data, internal storage, and cache. It may not work for all of them, but its ok.
***you must mount data again in TWRP after doing this, or you will not be able to see anything***
7. Copy & paste my nandroid onto your device in the correct location (sdcard/TWRP/BACKUPS/XXXXXX)
8. Restore my nandroid and try to boot.
9. If it still does not boot at this point, then you need to run these adb commands (while in TWRP) that @bogomil4e kindly reported to wipe the EFS partitions
adb shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst1 bs=16384 -and-
adb shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst2 bs=16384
Now you should be able to boot up and do anything you want again. Please do not mirror my nandroid or take advantage of it - I am making it available only for people to utilize as a way to unbrick their phone!

And that didn't work either. To be clear I left my bootloader unlocked. Each process works as far as flashing all the files via fastboot. But if I try to reboot or boot recovery, stock or custom, I boot loop. I have been looking everywhere and I dont see a solution and was hoping to get some help.
edit: Now I have also tried this... Doesnt seem to be the bootloop of death.

Read First: This method is relatively drastic, and will hurt device performance some. You should only use this as a last resort, if the more basic methods of fixing a soft brick didn't work (e.g, factory reset, flash stock firmware, etc.)​
*Update 8/22: Android O is working with 4 Cores now! Big thank you to @xls654 for finding out how to get Android O to work.
*Petition:
I made a petition for Google to officially release and sign modified boot.imgs, so that people with locked bootloaders can fix their devices too. Check it out here. (I apologize for dumbing it down so much, I wanted to make sure everyone could understand it)
*Changelog:
8/25 - EX kernel for Android O added.
8/22 - Android O DPR6 boot.img and source added.
8/16 - Started making this fix open-source, source code section added in OP. Also uploaded modified Franco and Flash kernel & source.
8/10 - Added PA 7.2.2 and DarkROM boot images.
8/08, 2nd change - Uploaded modified boot.img for firmware 48C.
8/08 - Updated EX kernel to version 4.1.2. This updated zip adds the CPU utilization patch to the init.elemntalx.rc, instead of removing the old init.angler.rc and copying the new init over. That should mean more compatibility with Roms/kernels that modify the init.angler.rc. I also modified the camera-daemon to use cpus 0-3 instead of 0-2, so hopefully this should make the a camera bit faster too.
8/07 - Added boot.img that only uses 1 core. Someone suggested I make a boot.img that only uses 1 core, just to see if it works for devices that didn't work with the 4 Core fix.
7/30 - Added universal EX zip, this zip should modify your kernel to use only 4 cores, and it should modify it to utilize all 4 cores. You can flash this over most ROMs and it should work. Also added a donation url, and this changelog.
7/29, 2nd change - Added Pure Nexus and PA dev version boot images, modified to use 4 cores, and utilize all 4.
7/29 - Updated this fix to greatly improve performance. Before this fix, the device was only using 1 core for foreground tasks, now it will use all 4 cores. Also revamped OP.
7/21 - Fix created, stock boot.img, TWRP image, and EX kernel modified to use 4 cores.
*What this fix does, and how to apply it:
The problem:
The problem with most of the devices in a BLOD, is that a hardware failure related to the BIG cluster has occurred. This fix remedies the problem by disabling the BIG cores. Unfortunately, this does mean that you will take a performance hit. However, I am continually working on ways to improve the device's performance.
The update: If anyone remembers device performance with the first fix, it was hurt a lot, however, after finding out that the device was only using 1 core for all foreground tasks, I modified the ramdisk to utilize all 4 cores more effectively, and it helps a lot.
Requirements: For this fix to work, you need:
A brain
A computer
A bootlooping 6P with an unlocked bootloader/OEM unlocking enabled
The modified files of your choice
Fastboot on your computer (preferably installed system wide). If you do not know what this is, or do not have it, look at this post. Answer yes to all of the prompts to install it.
How to apply the fix:
Boot your phone into bootloader (hold power and volume down).
Connect your phone to the computer.
Go to the folder where you have the modified files, then hold shift and right click in a blank space, click on "open command prompt here" in the menu that pops up.
In the command prompt: type "fastboot flash boot [name of the file here]" and then press enter. If you're flashing TWRP, replace boot with recovery. (Linux users, make sure you're running as root)
Edit: With the new EX zip, you shouldn't need to flash the boot.img anymore, you can just flash twrp, and then flash EX in twrp.
Boot up your phone, and hopefully it should work!
*If your phone is bootloader locked/OEM locked:
You can try to get your phone to boot long enough to enable OEM unlocking. Some users have reported success by freezing their phone for a bit, then booting it. Others have let their battery drain all the way, and then tried to boot their phone, but the most successful method seems to be heating up your phone (a lot).
If you do attempt any of these methods, make sure you have time and patience, as it will take a long time.
To enable OEM unlocking and unlock bootloader:
Go to settings.
Go to developer options, if you do not see that, go to "about phone", scroll to build number, and then tap it 7 times. You should now see developer options in settings.
Once you're in developer options, click on "OEM unlocking" and accept the prompt.
Now reboot your phone to bootloader, connect your phone to the computer, and type "fastboot flashing unlock" Your bootloader should now be unlocked.

Boot.img from stock 6.17, 8.0 firmware: Download | Mirror. This Image is the from the first official release of Android O, and is modified to use 4 cores. It also disables forced encryption as a bonus. Thank you to @xls654 for figuring out how to get Android O to work.
Boot.img from stock 48C, 7.1.2 firmware: Download | Mirror. This Image is modified to use only 4 cores, and is modified to utilize the 4 cores more effectively. I have had multiple people say that first boot takes a while after flashing this, so just wait about 20 minutes before you declare something is wrong with it.
Boot.img from stock 48B, 7.1.2 firmware: Download |Mirror. This Image is modified to use only 4 cores, and is modified to utilize the 4 cores more effectively.

TWRP version 3.1.1: Download | Mirror. This TWRP image is modified to use only 4 cores.
EX kernel version 5.03: Download | Mirror. EX kernel 5.03 works with android 8.0.0. This zip applies the 4 cores patch, but you will need to flash it over an already modified boot.img to work.
Elemental X kernel version 4.12, universal zip: Download | Mirror. This zip is EX kernel, modified to use only 4 cores. Update: I modified it to apply the CPU utilization patch too, so now this is a universal zip, flash it over almost any ROM, and you should now have the BIG cores disabled fix, and the little core utilization fix.
Flash kernel version 2.5: Download | Mirror. This zip is modified to use only 4 cores, and utilize all 4. Works with android 7.1.2. You can flash this over almost any ROM, including stock, and it should boot again.
Franco kernel r55: Download | Mirror. This zip is modified to use only 4 cores, and utilize all 4. Works with android 7.1.2. You can flash this over almost any ROM, including stock, and it should boot again.
You will most likely not need these images. It will be much easier, and much more universal to flash one of the custom kernel zips above ^^^
PA boot.img from PA version 7.2.2, build 8/10: Download | Mirror. Uses only 4 cores, and has core utilization patch.
PA boot.img from PA version 7.2.1: Download | Mirror. Boot.img from PA dev preview 7.2.1, uses only 4 cores, and is modified to utilize 4 cores more effectively. Flash it after you flash the PA zip, either with fastboot, or TWRP image flash.
Pure Nexus boot.img from Pure Nexus 7/25 build Download | Mirror. This image is modified to use only 4 cores, and it has a tweak to utilize the 4 cores more effectively. Flash it after you flash Pure Nexus, either with fastboot, or TWRP image flash.
DarkROM boot.img from 7/21 build: Download | Mirror. This image is modified to use only 4 cores, and has the utilization patch.
Boot.img modified to use only 1 Core. Some people were reporting that the 4 core images weren't working for them, someone suggested that I make a 1 core version to see if that helps at all. Edit: seems not to help unfortunately. Here it is: Download | Mirror
Unfortunately, I have not been able to get Android O working yet, but I am working on it right now.
If you have a favorite custom ROM or kernel you want to ported over to use 4 cores, let me know, and I'll put it up.

*Tested custom ROMS/kernels
I have used Pure Nexus by flashing the modified EX zip over it, it has notably better performance than the stock ROM, and very good battery life. It's a clean, stable ROM, with plenty of good features that are actually useful.
I have also used Paranoid android dev preview, very good performance, definitely my favorite as of now. Battery life leaves something to be desired, but I have not tried a custom kernel yet. Also, 7.2.1 seemed smoother to me than 7.2.2.
If you have a custom ROM/kernel that worked for you, let me know and I'll put it up here.
*To improve performance slightly:
Flash a custom kernel. I will upload more kernels as I test more, so stay tuned.
Overclock the little cores. It can slightly help offset the lost performance, on my 6P, I have mine overclocked to 1632MHz, and it works perfectly for me. Edit: I actually recommend not overclocking. Many people have reported their Little cores failing, so I would go for longevity on this device, and keep it at stock clocks, or even underclock it. The speed difference you get from overclocking is negligible anyways.
Disable animations in developer options. Seriously, as soon as I found out about this tweak, I've used it on ever single device I've owned, it helps a ton.
Turn resolution down to 1080p. On a small screen, the difference in between 1080p and 1440p is not very noticable. To do this, first get root access, then download a terminal emulator. In the terminal, type "su" and grant it root access, then type "wm size 1080x1920", and finally, change the density "wm density 400". Personally, I like my density at 400, but you can expieriment with it. Lower density=Smaller items and text, Higher density=Bigger items and text. Also @Adithya FRK mentioned that you also want to put density in build.prop so apps display correctly. Change ro.sf.lcd_density=560 to your density, if you changed it.

FAQs
What's the password for TWRP/Why is TWRP asking for a password? - In android 7.0, Google added forced encryption to the data partition. To get around this, click cancel when TWRP asks you for a password, and then factory reset the device. Then you can flash EX kernel/Magisk to disable forced encryption.
Why am I getting an error when I try to flash the images? - Your bootloader is probably not unlocked, try running the command "fastboot flashing unlock", If you get an error there too, then you will have to enable OEM unlocking before you can continue.
It's not working for me, how do I fix it? - My only advice for that is: "Flash the stock firmware for whatever version image you're trying to flash, then reflash the images again" If you're stuck on the boot animation, wait at least 20 minutes before you declare it's not working. If none of that works, chances are your device may have a different problem.
Does EX kernel have the new speed fix? - Yep, you can flash this over just about any ROM, and it should patch it to use only 4 cores, and use them well.
I would like to help as many people as I can, however, I am much more likely to be able to easily help you/reply to your post if you clearly state your problem and the steps you attempted to fix it. I will be much less likely to reply to posts such as "omggg i flashed the image and my phone won't boot helppp" Please read through post first, I did not spend time typing up this OP for no one to read it. If I can see that you read through the OP and have attempted all the steps, then I will be much more willing to help you.
I set up donations on my profile, for those of you who want to donate. I have spent countless hours modifying, flashing, testing, and helping, don't get me wrong, I love doing this and helping y'all out, but donations really keep me motivated to keep going, and donations also will help me fund new equipment and devices that will help further my android development.

Anybody have any insight?

Were you successful at returning to stock?
If not, I'm afraid you're suffering from the bootloop issue :'(

No i was not, but the standard 4 core fix isn't working for me either so I don't know what else to do.

I did something similar. Tried to update to latest may patch from custom rom. No sim found...so tried some radios..nothing. Thought I better get back to full stock. Similar to you tried the individual flashes and then the OTA as a whole. During that process I locked the bootloader. Now I get the yellow screen text says software isn't standard...then google logo...then the red text says os is corupt possibly...then google logo, forever. No loops it seems but just doesn't boot.
Anyone with thoughts?

i am on my 2nd 6p with the same problem after installing twrp. the first one i got operational by sideloading via twrp a factory img. to get the sideload to work i had to go back to android 6, 7 and 8 would not work. right now the google firmware site is not working, it has been out for a few days, so i have not been able to try it on the second 6p.
edit; now that i recall the factory img would not load after installing. i then went back to fastboot recovery and got the distress robot, twrp was of course gone. from there i did a factory reset which got me back to go and the long climb back to oreo.
