Can't boot into twrp on DP4 - Nexus 6P Q&A, Help & Troubleshooting

hello I'm trying to make a nadroid backup before updating to dp5 but Everytime I try to enter twrp it won't boot past the twrp splash screen.. how can I fix this? It's worked before for me on dp4 and I didn't do anything that would cause this that I know of.
Does anyone have any suggestions? Thanks.

Re-Flash the latest TWRP recovery using Fastboot:
Code:
fastboot flash recovery recovery.img
Then, try again. If not, you can use:
Code:
fastboot reboot-bootloader
followed by
Code:
fastboot reboot recovery

Last I knew twrp cannot decrypt the developer previews

TWRP does not work on DP, it just stays stuck on the TWRP flash screen. If you want to get it to work, just flash the marshmallow vendor.img over adb, boot in TWRP and do whatever you want to do there and then flash the android N vendor.img.

TWRP 3.0.0-0 works on both DP4 and DP5 but it won't decrypt.

Will I be able to make and restore nadroid backups with twrp 3.0.0-0?

TWRP doesn't play nice with the developer previews. hopefully, this will get fixed for the eventual final release of N, but until then you can just use a M vendor image and then for some reason TWRP works fine. see this guide here: http://forum.xda-developers.com/nexus-6p/general/guide-android-nougat-developer-preview-t3410906
The only difference for you when following the guide is that after you're in twrp, instead of flashing supersu, you'll make a nandroid backup. then you'll go back to the bootloader, and flash dp5, then back to twrp to root, and finally back to the bootloader to flash the dp5 vendor.img.

Shamelessly ripped from my reddit posts. Minor edits from original.
Here's what I did, including complete backup/restore (this assumes you are rooted), on DP4. The same process worked on DP5. Unfortunately, you have to format data in order to get it to work.
I don't know your skill level, so I'll write this as simply as I can, for those who might arrive here from Google.
WARNING The steps provided in this guide could potentially brick your phone if done incorrectly. I am not responsible for the decisions you make that may permanently or temporarily damage or destroy your phone. Use at your own risk. If you are not sure what any of the steps are STOP and ask questions!
Here we go
Download Titanium Backup from play store (pro may be required for some features described here, not sure, I have it)
Use TBU to backup all user apps. There's a batch action for exactly this (I stopped doing system apps on MM+ because it seems the permissions get borked on a different Android ID, and I end up having to factory resetting anyway)
Use TBU to generate an Update.zip from backed up apps (again, in the batch actions, at the bottom).
Download Super Backup to backup SMS/call log history (WARNING MMS will be lost in this, including group texts, I know of no way around it)
Copy contents of internal storage to PC. Sometimes you can get Android Commander / Droid Explorer to work, and it's faster, but I was not able to with DP4.
Download the modified bootloader for your version of android from the Nexus 6P on XDA (if you're unsure, Settings->About Phone->Build Number)
Reboot into the bootloader
Run the following commands:
fastboot format userdata
fastboot flash boot <your-modified-boot-image>.img
fastboot reboot-bootloader
fastboot flash recovery twrp.img
Reboot to recovery
Perform factory reset from within TWRP
Boot into Android
Perform the first run setup
Enable USB debugging from Developer Options IMPORTANT!
Enable "Unknown Sources" from Security settings IMPORTANT!
Put the files that you backed up from your PC back on your internal storage
Rename the folder /SDCard/TitaniumBackup to /SDCard/TBU. If you do not do this, when you restore Titanium Backup, it will delete everything in your original backup folder. We need this just in case the Update.zip will not flash.
Download the latest SuperSU to your phone
Reboot to recovery
Flash SuperSU
Flash the Update.zip that was generated from TBU *Sidenote here
Reboot to Android
TBU will restore data for your apps (some may fail, unavoidable)
Restore SMS / Call logs using Super Backup
Profit
*Once when I was doing this for a friend, his TBU-generated Update.zip would not flash (error 7). Do not panic, because as long as you followed directions, you can fix it. If it fails:
Reboot back to Android
Download TBU from the Play store
Go into Settings->Preferences->Backup Location and change it to /SDCard/TBU
Run the batch action to create another Update.zip (rename it something else, just in case)
Reboot back into recovery
Flash the new Update.zip
Reboot back into Android
Let me know if something was unclear, or you have any questions!

How to Root without flashing custom recovery

HOW TO ROOT YOUR DEVICE WITHOUT FLASHING RECOVERY
This can be done with two methods.
ADB or FASTBOOT.
I have tested both methods and they worked for me.
I tested this on JSS15J. I am not sure about any other versions but I guess it should work.
SOME BASIC INFORMATION
Usually when you want to root your device, you must have UNLOCKED BOOTLOADER.
A CUSTOM RECOVERY is usually used to flash SuperSU to gain root access.
CUSTOM RECOVERIES ARE USUALLY FLASHED (they permanently replace your stock recovery)
In this guide, You BOOT into custom recovery by going into BOOTLOADER and then using fastboot/adb tools to flash SuperSU .
Booting is temporary and thus once you restart from recovery, the custom recovery will be gone
Make sure, you have USB debugging mode enabled. To go into bootloader you can either use adb commands ( Type [adb reboot bootloader] in cmd in platform tools directory with your device connected) or do it manually by turning it off and then holding power and volume down.
You must also have platform tools of SDK (Fastboot and ADB) for this to work. MAKE SURE YOU OPEN CMD into the folder where platform tools are present.
Try it on OWN risk. I will not be responsible for bricked devices or any damage.
ADB METHOD
Connect to your PC and make sure USB debugging is on.
COMMANDS IN BRACKETS. DON'T WRITE THEM. COMMAND WOULD BE LIKE : fastboot boot recovery.img
MAKE SURE YOUR DEVICE HAS UNLOCKED BOOTLOADER
(fastboot boot [recovery.img])--------------------- Name of recovery to be here
Mount /system and push the necessary files once the recovery has started:
(adb push su /system/xbin)
(adb push Superuser.apk /system/app)
Set correct permissions:
(adb shell)------------------------------ You have got into your device's shell
(chmod 06755 /system/xbin/su)
(chmod 0644 /system/app/SuperSU.apk)
(exit)
Reboot:
(adb reboot)
FASTBOOT METHOD
This is relatively easier as you will boot into custom recovery temporarily and then flash ZIP of SuperSU. Afterwards I recommend to clear davik cache and restart.
UNLOCKED BOOTLOADER REQUIRED
Boot into bootloader.
Type these commands to boot into custom recovery. This will not flash recovery and you will have stock recovery once you restart.
fastboot boot recovery recovery.img where recovery.img will be the file name of recovery
(After 4.4, use this command "fastboot boot recovery.img" instead of above mentioned)
After booting into reccovery, flash SuperSU and you are done.
I recommend clearing dalvik cache before leaving and restart.
And you are done.
YOU CAN ALSO USE A PREROOTED KERNEL WHICH YOU CAN FLASH VIA FASTBOOT. I AM NOT SURE IF THERE IS ANY
For information on how to retain root after OTA, please refer to this :
Update Super SU is also taken from this guide.

If you are stuck in a bootloop, make sure you have cleared dalvik cache in custom recovery.
I got bootloop when i tried with fastboot method as I was new to twrp, I explored it a bit and tried to remove system and tried overwriting data to see how it is different from CWM and check its strength. I got an error clearing cache so I rebooted into custom recovery to clear dalvik and my nexus booted fine (DON'T TRY THIS, JUST CLEAR CACHE AND WIPE DATA and restart)
REMEMBER, UNLOCKING BOOTLOADER WILL DELETE ALL YOUR DATA AND DOING WIPES WILL ALSO DELETE ALL YOUR DATA.
DALVIK WON'T DELETE YOUR DATA BUT
MAKE SURE YOU HAVE MADE A BACKUP using BACKUP PRO (non rooted) or Helium (non rooted) and Titanium Backup Pro (Daah, you are not rooted so this won't work)
GOOD LUCK
Booting into custom recovery to install root works fine.
As you mentioned unlocking bootloader is still a prerequisite.
You may want to just use the SuperSU install zip though. Though I haven't tried Superuser on this tablet, it is my understanding it hasn't been modified to work with 4.3 security. That may have changed since I last looked so if you find differently please post. SuperSU added a daemon mode to deal with 4.3 security changes.

The trick here is to BOOT into custom recovery BUT not FLASH recovery permanently. Once you restart, the CUSTOM recovery will be gone.
You can use simple commands if using Fastboot
fastboot boot recovery [recovery name.img]
This way you will install SuperSU using recovery which is relatively easier than ADB commands.
You will only go into recovery temporarily.
I also read a forum where you can preserver root even after OTA/ Updates.
[UPDATE]

Do check that out as well.
I tried this with Twrp and superSU.
I got bootloop as I have been always CWM person so I accidently tried to delete system too with dalvik cache and hard reset and I got an error
However, I boot again into recovery and cleared wipes and the bootloop was gone

You restart your device. Boot into bootloader and use fastboot to Boot into custom recovery(command given in post above).Once Into recovery, you can easily clear dalvik cache.
And remember, it might not require clearing cache because I was exploring twrp n overwriting data n tried To delete system to see how powerful the recovery is. I will update guide now

The "fastboot boot recovery recovery.img" command is not working anymore. The command prompt returns with a "cannot load recovery" error. At least that's what it does on my Nexus 7 running Android 4.4.2.
This seems to affect Android 4.3 and upwards according to this Nexus 4 thread: http://forum.xda-developers.com/nexus-4/help/solved-fastboot-boot-recovery-img-t2380675
There's a workaround with a different fastboot command line as mentioned in the thread. I wonder if there's also a fix for the Nexus 7. Any replies would be greatly appreciated.

Those who finding difficulty in rooting Nexus 7 (2013) can use Wugfresh Nexus Root Toolkit. It is so powerful that you would find every function you would like to do on your Nexus 7, from the comfort of your PC. Also watch qbking77 's video on using the Toolkit for further information.

[INFO] How to sideload 5.1.1 (LYZ28E), & maintain no encryption - no wipe required

[INFO] How to sideload 5.1.1 (LYZ28E), & maintain no encryption - no wipe required
Simplified procedures with LMY47M / LYZ28E now available as a factory image.
Hopefully this isn't blatantly obvious to everyone, it is a little different than the normal sideload procedure. Thought it might be useful to some who want to load 5.1.1 (and get Wifi calling with T-Mobile!) and not be forced to encrypt.
Requirements:
1. I'm assuming you have adb/fastboot working on your computer / connecting to your device and you understand a little bit about using adb / fastboot with an android phone.
2. Your phone cannot be encrypted, if you're encrypted already - this will not un-encrypt your data - you need to turn off forced encryption and format the "userdata" partition to disable the encryption.
3. You need to have an unlocked bootloader for this to work of course.
How to follow this procedure:
1. If you're on LMY47M (T-Mobile) and unencrypted, you can follow option 2, starting with Step 3 - only a small ~150MB download required.
2. If you're on anything other than LMY47M, you should use option 1 unless you have a desire to flash LMY47M and sideload LYZ28E.
I didn't do much here - except spent a bunch of time writing the procedure.

- TeamWin - the TWRP Developer ( https://twrp.me/ )
——————————————————————————————————
OPTION 1 - Easy Method - Flash the LYZ28E factory image directly:
1. Download hlxanthus's NO FORCE ENCRYPT mod and put it onto your phone so you can flash it later (in /storage/sdcard0) - https://basketbuild.com/filedl/devs...u/misc/NO_FORCE_ENCRYPT_shamu_v1.0-signed.zip
2. Download LYZ28E for Nexus 6 ( https://dl.google.com/dl/android/aosp/shamu-lyz28e-factory-b542b88a.tgz ) and extract the files, there is a zip file you want to extract that too.
Boot to the bootloader ("adb reboot bootloader") and fastboot flash the boot, cache, recovery, radio and system:
Code:
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img (OPTIONAL - If you have TWRP or another alternative recovery you can skip this step)
fastboot flash radio radio-shamu-<variable>.img
fastboot flash system system.img
3. Restart the Bootloader, and flash TWRP, found here: ( https://twrp.me/devices/motorolanexus6.html )
Code:
fastboot flash recovery twrp-2.8.6.0-shamu.img
4. Restart the Bootloader again and then go to Recovery (TWRP). Now flash NO_FORCE_ENCRYPT_shamu_v1.0-signed.zip through TWRP, and flash SuperSU if you want root and whatever other zips you want to flash (Xposed, etc)
After flashing the NO FORCE ENCRYPT mod, reboot and you should be running 5.1.1 with all of your data and with your userdata partition intact and unencrypted!
———————————————————————————————————————————————————
OPTION 2 - SIDELOAD Method (Makes sense if you’re already on LMY47M):
1. Download hlxanthus's NO FORCE ENCRYPT mod and put it onto your phone so you can flash it later (in /storage/sdcard0) - https://basketbuild.com/filedl/devs...u/misc/NO_FORCE_ENCRYPT_shamu_v1.0-signed.zip
2. Follow the normal procedure, if you're already on LMY47M you can skip to step 3. Download LMY47M for Nexus 6 ( https://dl.google.com/dl/android/aosp/shamu-lmy47m-factory-5228e84a.tgz ) and extract the files, there is a zip file you want to extract that too.
Boot to the bootloader ("adb reboot bootloader") and fastboot flash the boot, cache, recovery, radio and system:
Code:
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash radio radio-shamu-<variable>.img
fastboot flash system system.img
3. Now flash TWRP, found here: ( https://twrp.me/devices/motorolanexus6.html )
Code:
fastboot flash recovery twrp-2.8.6.0-shamu.img
4. Restart the bootloader, and enter recovery mode (TWRP). Once in TWRP, go to Advanced -> ADB Sideload. You may need to unplug/plug in the USB cable to your computer again.
Download my version of LYZ28E from here: https://www.androidfilehost.com/?fid=23991606952609905
Note: I modified this version to work with TWRP, it will not work with the stock recovery (because I modified it, the signature on the file is now invalid). The only thing I changed was I edited the updater-script to remove the release keys check which seems to fail on the stock recovery and doesn't work right with TWRP).
Code:
adb sideload f69096766706fab3c721163f02aad9073a989d00.unsigned-shamu-LYZ28E-from-LMY47M-fullradio-fix-superblock-use-TWRP.zip
5. After it finishes, do not reboot yet. Go back and I recommend rebooting to recovery again. Now flash NO_FORCE_ENCRYPT_shamu_v1.0-signed.zip through TWRP, and flash SuperSU if you want root and whatever other zips you want to flash (Xposed, etc)
After flashing the NO FORCE ENCRYPT mod, reboot and you should be running 5.1.1 with all of your data and with your userdata partition intact and unencrypted!
why would you think that you have to be encrypted to push anything to recovery??? plus sideload is only one method to do it, the other is adb push. and if you use twrp recovery, you don't need any of those method's, as you can just move files over to twrp via your usb.

Sorry if I gave the impression you need to be encrypted to push to recovery, that wasn't my intent. Where did I give that impression? I can try to fix it in my original post. At no point in this procedure will your phone be encrypted - there will be times that the kernel will have the force encryption option turned ON in the fstab but you never will boot the phone when that is the case (like right after LRX22C is loaded, after LYM47M is sideloaded, and after you flash the stock boot.img for LYM47M - but you are not booting in any of these cases - not before you install a no forced encryption kernel)
adb push requires the phone is booted right? I wasn't able to get adb push to work in recovery.
I also didn't know TWRP allowed you to copy data over to your phone via USB, I know CWM recovery can do it - but that was a feature missing from TWRP - maybe they added it, I didn't check. You can do an adb push with TWRP, but what in my procedure would you change to use the adb push method in TWRP versus whatever I put in there? The only thing I can think of is asking you to put the mod file on the phone in the beginning.

"So I just figured out how to sideload LYZ28E on my Nexus 6 without enabling forced encryption. "
actually adb push is very easy.. boot unto recovery, type adb push filename.zip, then it pushes to your phone and is listed in the main storage filesystem. id say its nearly identical to adb sideload.

Sorry maybe that first sentence is poorly worded. What I meant was, I figured out how to get LYZ28E onto my phone and disable the forced encryption on the OS too. The process wasn't as straightforward because the 2nd sideload wouldn't work correctly without booting into the OS first. After that, I couldn't get the LYZ28E image to sideload on stock recovery or TWRP without errors - but I was able to modify the LYZ28E OTA file so it would load with TWRP, and then I was able to load the no encrypt mod and supersu and get the phone working the way I wanted again.
Are you saying it would be easier if I push the zip file to the phone and install using TWRP as a zip file instead of trying to sideload it?
Step 3: "Hold down the Power and Volume Up button (may need to do it a few times) to get to the Recovery menu".
Actually, the correct key combination is: Hold power, then (while holding power button) press and release volume up.
Works first time, every time.

This is where I was, LMY47E, rooted, unencrypted and with TWRP. I followed the entire procedure - went back to LRX22C using fastboot, then sideloaded LMY47M (T-Mobile version) - then flashed the no force encrypt boot.img - booted, after it finished booting, rebooted to the bootloader and so on ...
When you go to LRX22C you flash back to the stock recovery. So you need to boot into the stock recovery, pick "apply update from adb" and then run the adb sideload command from the PC.
Cheers for this.. just what I was looking for. I'm at work so I only scanned this quickly, but any major change in the directions from what you've posted going from an unencrypted LMY47D?
With the factory images being posted, I just did the following:
Flashed the factory images
While still in bootloader, flashed TWRP
Rebooted into TWRP
Pushed SuperSU and the No_Force_encrypt to the /sdcard/ partition
Installed via TWRP
Profit.

For LMY47D you need to get to LMY47M first, so you would follow the entire procedure, downgrade to LRX22C and then sideload LMY47M and so on.
Heavily updated the procedure since LMY47M and LYZ28E factory images are now available directly from Google.
Should be a lot easier and more straight forward now!
I just recently have this Nexus 6 and came from an LG G2. I went through the process of unlocking the phone and installing rooted LMY47D which meant 2 factory resets in a short period.
I'm now on 5.1 and would like to get rid of the memory leak which this build apparently has.
The title mentions "maintain no encryption".
I never found the time to find out about Lollipop. The title implies that encryption is mandatory on 5.1.1
Is this so?
I merely want the latest upgrade to 5.1.1 and don't want to enforce encryption on my data (Google already knows everything about me) is this the way to achieve this?
I am correct in thinking that I will not get an OTA offered anymore?
Boot loader and radio only...
So if I understand the instructions correctly, if you are still encrypted but rooted, from any Lollipop installation, fast boot flash the factory images... then flash TWRP ... root and done right? Then I have another question... the kernel I am running EX 1.07 along with Flar's app is running perfect for me.... any dangers in just flashing the boot loader and radio? I would like to wait on the system part until the kernel has been updated.....
Also, if I needed to do a restore, if I only flash the boot loader and radio have I pooched being able to go backwards to a nand backup?
FYI, step 3 in option one should read:
fastboot flash recovery twrp-2.8.6.0-shamu.img
vs
fastboot flash twrp-2.8.6.0-shamu.img

I just recently have this Nexus 6 and came from an LG G2. I went through the process of unlocking the phone and installing rooted LMY47D which meant 2 factory resets in a short period.
I'm now on 5.1 and would like to get rid of the memory leak which this build apparently has.
The title mentions "maintain no encryption".
I never found the time to find out about Lollipop. The title implies that encryption is mandatory on 5.1.1
Is this so?
I merely want the latest upgrade to 5.1.1 and don't want to enforce encryption on my data (Google already knows everything about me) is this the way to achieve this?

Starting with Android Lollipop (5.0) and newer - at least on the Nexus 6 - encryption is turned on by default for the userdata partition.
You would - if you wanted to - backup all of the data on your userdata partition (e.g. Any pictures you've taken with the phone, etc - all of the data basically that shows up when you plug your phone into your computer).
Then you need to be running an OS that doesn't force encryption (for example if you follow my instructions) - this would also get you running 5.1.1.
After that you need to format your userdata - it wouldn't be encrypted at that point, and then copy your data back if you want to.
If you don't care about encryption, you can simply flash the factory 5.1.1 image following my instructions and skip the TWRP parts.

Help with bootloop

Hi,
I did search, but I didn't find any solution to the issue. I got the Nexus 6P 64 GB.
I unlocked my bootloader using the 6p Multitool. Thereafter I used my normal method of fastboot (Minimal ADB) to flash the boot.img from this thread http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344.
After that I flashed TWRP. Basically I followed the instructions here: http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928.
But my phone is not booting up.
It gives me this error:
Your device software cannot be checked for corruption. Please lock the bootloader."
But I tried that and it doesn't work. I tried from fastboot restoring to factory, but get the same message.
Please help me!
Did you check the enable oem unlocking in developer settings?
Sent from my Nexus 6P using Tapatalk
Yes. As I said, I achieved the unlock. Now I just can't get back into my phone or recovery or anything other than fastboot (where it says unlock)
isn't "Your device software cannot be checked for corruption. Please lock the bootloader." the new msg on boot when you are unlocked, and you have to wait ~10 secs before it startup ?
After that, I'm stuck on the Google screen. It just goes on and on. Left it for over 20 minutes at one point and it didn't get past it.
Edit: The multicolored animated google screen. The animation just keeps going and going.
Del.
Your issue might be due to the encryption of the phone. Take a look at this thread: http://forum.xda-developers.com/nex...recovery-twrp-2-8-7-0-touch-recovery-t3234976
From this thread:
NOTE: Decrypting data is not supported yet. The Nexus 6P will normally attempt to encrypt the device automatically on first boot. To use TWRP as you normally would, you will have to format data and install a slightly modified boot image with forceencrypt disabled. My Nexus 6P should arrive tomorrow and I will start working on decrypt once I get my hands on it.
Team Win Recovery Project 2.x, or twrp2 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
Read through that thread. Part of the issue is that I don't know which variant (MDA89D & MDB08K) I have, or how to find that out seeing as I can't boot into the phone.
If I have the variant I may be able to fix this through the unified toolkit (though I'm not sure of that)
Did you ever fix this?
Try flashing the factory image and starting from scratch. You must have messed up somewhere. Re-download the boot.img from Chainfire's thread, maybe that was corrupt or something.
1. Download the MDB08K factory image (it's not a variant, it's a Marshmallow update) and unzip it.
2. Download the MDB08K boot.zip from Chainfire's modified boot.img thread
3. Download latest SuperSU beta zip
Wipe phone in TWRP, to include format data.
In bootloader, fastboot flash MDB08K
fastboot flash modified boot.img (from zip)
In TWRP, ADB sideload SuperSU
Reboot and it should perform normally.

Thank you for your reply, but I can't get into TWRP either!! Any way for me to restore to factory or do the repairs from in flashboot without the restore?
I ran into the same issue last night trying to install TWRP. I'm still not sure how to get around it but I did get my phone back. you should be able to get to the bootloader (hold the power button until phone turns off, then hold vol up+vol down+power) once there use ADB fastboot to go back to stock.
this link will walk you through what you need. follow step 7.
http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
here it is as well:
How To Flash The Factory Images (And Return To Stock)
Prerequisites: unlocked bootloader (section 1).
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-01.31.img
radio-angler-angler-01.29.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-01.31.img
cache.img
radio-angler-angler-01.29.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-01.31.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-m8994f-2.6.28.0.65.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash userdata C:\angler\images\userdata.img
fastboot flash vendor C:\angler\images\vendor.img
Thank you. I was eventually able to do tysonwald's suggestion. First I didn't know what my version was, so I couldn't.
At some point I was able to get into the phone with constant gapp errors, check it.
Now my phone is unlocked and rooted. But when I go to settings to security (and when I tried to set up my fingerprint) settings crashes. Any ideas?
There was still some issue. I wiped the phone with the above method again, did NOT set up twrp/root, and everything works. It was something about the custom boot image I guess. Any advice if I want to try to set it up again?
Problem solved. Needed to update to newer image before doing everything. Issue resolve from Heisenberg's thread. Thank you all!
I had the same damn issue last night. Thise bootleg instructions had me flashing build k boot.img on build D. Maybe i wasnt paying attention lol!
I have a very similar problem, I flashed the k boot img. and now I'm stuck in an endless bootloop any idea?

Read thru this guide and follow the instructions to the T. http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
I had a similar issue just now where my phone got stuck at the TWRP logo. Selecting the reboot option in download mode refused to remove it. I had to follow step 10 to get my phone back to stock. I'm afraid to try this again now
Is there anyway to know which version do i need to download? i bought the phone already bricked and i am trying to bring it back to life

Help Me Root This Thing! XT1575

I've done a lot of research on a reliable way to root my Moto X Pure Edition XT1575 and want someone to check my plan before I pursue this. I'm gonna download TWRP for Clark and superSU 2.78 and put them in the same folder and open up the command prompt in that folder. Then hook up to the PC and enter the following command "fastboot boot twrp.img" then I'm gonna replace the twrp.img with the name of the twrp file and backup to the SD. Then reboot into the bootloader again and flash twrp with fastboot "fastboot flash recovery twrp.img" then start recovery and go to reboot into recovery again to lock it in. Then I'm booting back into twrp and going to Advanced & Terminal and entering the following command "echo SYSTEMLESS=true>>/data/.superSU then back home then flash superSU 2.78.
Please correct me on everything that may be wrong. If there's a better way to root, tell me how to do it your way.

You've researched well. Couple things: The command is "echo SYSTEMLESS=true>>/data/.supersu", you added capitols on supersu. Next your first command of "fastboot boot twrp.img (or whatever you rename the TWRP recovery image to)" will live boot TWRP, which for our device is not necessary. Live booting is essentially booting into a custom recovery environment without actually installing the recovery. This is useful for devices that DO NOT have factory images available, which allows you to make a backup in the live environment prior to altering your device. We have factory images and factory recovery images, so you can skip this step and go right into "fastboot flash recovery twrp.img (or again, whatever you rename the recovery image to). Then after the recovery flash from within fastboot, you must reboot into recovery using the button select options within fastboot or your recovery will be overwritten by the stock recovery. Upon first boot of TWRP you'll have an option to keep your device read only or read/write. I personally choose NOT to keep it read only, rather read/write, because I don't care about taking OTA's with a custom recovery, but this is up to you. Then you'll want the supersu.zip on your device already (you want the regular standard current version, not a modded one from here: http://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703), either on your internal or external sd. And yes, prior to flashing supersu enter the command in TWRP without quotes "echo SYSTEMLESS=true>>/data/.supersu" (this prevents the bootloop that our device gets when flashing supersu in systemless mode). And your good to go. I just did this a few weeks ago from clean fastboot flashing the latest factory image, works perfectly.
Now for some clarity, I'd like someone else to chime in on the TWRP command "echo SYSTEMLESS=true>>/data/.supersu" that has to be entered. I know for sure entering the command prior works, and roots properly, but I have also read that the latest 2.78 version of supersu does not require this. I'd really like someone that KNOWS FOR SURE (no opinions) if this step can now be bi-passed, or if our device requires and will always require this step now and in the future. This will help solve a ton of questions about this issue that are spread throughout the forums so users don't have to dig to get a simple answer.
Thanks for taking the time to educate me on this. I'm gonna give it a try in a few minutes. Will I be a developer if I get it right? Hahaha I'll let you know how it goes

It worked! I'm rooted and looking for a stable rom with a lot of features and customizations that works with Verizon LTE. I also want viper4android. I'm glad I backed up because I tried flashing a viper4android zip and it caused my phone not to boot. It just sat at the unlocked bootloader warning so I just restored it. Evidently, I was supposed to unzip the file in esfile Explorer and install the apk. I think I also needed the selinux mode changer app.
What would I gain by installing a custom Kernel to my rooted stock rom? Can I even do that?

I literally did this to a fresh MXPE two weeks ago... misspelled the filename so it wasn't recognized (it isn't supersy apparently), and flashed SuperSU 2.78-SR1, rebooted and stuck at boot logo for 20 minutes. Rebooted into TWRP and entered the correct echo command to create the .supersu file and reboot, it looped twice quickly and then went to the lockscreen after a 2-3 minutes.

Flashable Recovery?

Hello, I know our great device does not have a recovery partition, so we need to use fastboot to boot TWRP. But muy question is, is there no way to boot into TWRP without a computer? Maybe a terminal command from Android itself, or a little script that we can run when needed? This might be a noob question, but I'm sure many here could profit from a positive answer.
Thanks

Assuming youre rooted... Ive used the reboot app on my phone. I have a 1926-7 Moto G6 Plus. It will boot to fastboot, fast reboot, recovery, reboot system etc. Look around xda and see if someone has a good reboot app or else use GP. I actually had twrp flashed permanently to my phone but it would not back up so I have to redo it. Also the phones data was encrypted and I didnt know how to fix it. I hope that you are able to find something that works for you
You can boot into TWRP via terminal command without using a computer. Use the 'dd' command ( 'dd if=/dev/block/bootdevice/by-name/boot of=/sdcard/boot.backup.img' ) to take a backup of your boot.img. Than use 'dd' to overwrite boot with twrp and reboot to recovery (dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/boot)
Later to boot your phone as normal you only have to install your boot.img backup via TWRP.
now we can install a TWRP 3.3.0 ONLY ON DECRYPTED ROMS (the lastest Havoc, Resurrection Remix, AEX, Decendant, PixyOS are unencripted by default) for flashing magisk modules or mods but it will be overwrite when we flash/update our custom/stock rom:
https://drive.google.com/open?id=1CqzvBiEfk9xucXG8UemNZMhBxDCeSV0i
How to install it:
Put the donwloaded TWRP on your plataform tools folder and in your internal/sd storage.
Boot the same TWRP (fastboot boot TWRP.img)
Go to ADVANCED and select Install Ramdisk Recovery
Check backup boot box( in case something goes wrong just restore your boot partition)
Swipe and wait until finish.
Reboot
If every reboot finishes in twrp booting just flash magisk and youll be able to boot into system.
