Hi, I am a happy owner of the HP Slate 7 Extreme which is basically the same device as you guys are using.I am still on the 4.2 Jelly bean since HP are not pushing over the air updates with our devices.I want to use the script from the development forum "[Script] [Utility] Nvidia Tegra Note 7 Kitkat Unlock BL, Restore, Recovery, & Root", I want to know if anyone has tried to use it with the Slate Extreme or if it simply should work on the Jelly Bean aswell. Thanks guys.

i have not test that yet but i believe it should work because i have tested the 4.4.2 and 4.2.2 evga ROM from here using the cwm install from sdcard method..
http://forum.xda-developers.com/showthread.php?t=2627671
The only thing that puzzles me now is i am unable to perform a system recovery from HP update.zip using cwm.
http://h10025.www1.hp.com/ewfrf/wc/...en&cc=us&dlc=en&sw_lang=&product=6608632#N147
So right now i am stuck with 4.2.2 evga ROM all is good and functional.
I have read some post that by updating OTA fix issue in 4.4 but i have no idea on how to get the OTA update.
p/s: This is my first tablet and root attempt...
edit:
i found out that rootjunky has already released the 4.4.2 with 2.3 OTA i will give it a try and feedback later

First, nope, you'll still get freezing. I've tried all the ROMs.
Second, If you want to go back to HP's recovery, do the following:
Create a copy of update.zip and navigate to META-INF\com\google\android and open up updater-script
Delete the first three lines.
Transfer your new update.zip to your device and flash. Allow it to re-write the recovery partition.
NOTE THAT YOUR DEVICE WILL NOT ADVANCE PAST THE BOOT ANIMATION. THIS IS NORMAL.
Copy the original update.zip to a SD card and insert it into the device.
Now go to the HP recovery partition that now exists on your device and follow HP's restore instructions.
You're done, the stock 4.2.2 that came with your device is now installed.
Had to figure this out the hard way after I lost my original backup.
To the original poster, you can get it to work, but you need to make modifications to the script's fastboot commands (they will require "fastboot -i 0x03F0" before they will do anything) and you will need to setup your machine for ADB with the Slate 7 Extreme. It won't work out of the box, you can find support for that here: http://h30434.www3.hp.com/t5/Android-Tablets-e-g-HP-Slate-7/ADB-drivers/td-p/2574571
There was an individual who has received the 4.4.2 update from HP on his Slate Extreme over at the HP forums. I believe he stated he received 20 units donated directly from HP and was wondering why only 1 of them received the update. I believe the reason stated is that he most likely received a non-retail unit by accident. Not sure if he ever dumped the ROM or even knows how. I don't know either otherwise I'd try to contact him to get him to do so.
Re-write recovery partition?

I did flash the modified update.zip but CWM doesn't give me the option to re-write the recovery partition. I go straight to "Install from sdcard complete". How is that re-write done?
*Update* All done - Had to select NO to questions on reboot (Replace recovery and root). Thanks so much - back to stock 4.2.2

I have the 4450 extreme and one the things that was a little different- is that I had put the update zip on the sd card prior and it did the update on its own... WEIRD but acceptable! rooted and on 4.4.2- thanks man!
I didn't have any luck doing it this way. I ended up getting there by a slightly different avenue.
My s7e was totally non functional beyong fastboot and recovery mode being operational. I ended up downloading tegratools 2.2. Using the fastboot included in that I unlocked my boot loader with fastboot by the command
Code:
fastboot -i 0x03F0 oem unlock
(The '-i 0x03F0' is a code relating to the specific model, apparently without this the tablet will ignore your command. Please also remember that the unlock factory resets the tablet.)
It may be overboard again, but I also formatted all the system partitions
Code:
fastboot -i 0x03F0 erase boot
fastboot -i 0x03F0 erase system
fastboot -i 0x03F0 erase userdata
fastboot -i 0x03F0 erase cache
fastboot -i 0x03F0 erase preinstall
fastboot -i 0x03F0 reboot
I uploaded cwm recovery from the above version of tegratools to my s7e as it seems a bit more forgiving with signatures than the stock recovery. I used that to upload a version of update.zip with the "assert" lines removed from META-INF\com\google\android\updater-script. I also self signed the .zip to reduce the likelyhood of my upload being rejected by the tablet, it may not be needed, but I did it anyway.
Code:
adb sideload slate7update-signed.zip
when completing the firmware flash, apparently there is a common problem of the kernel not flashing correctly when recovery takes place and giving an "Error 7", this is the problem I think you solved by re-writing the unmodified firmware (but that didn't work for me)
Anyway I had to fix it by dropping back to fastboot and flashing it to "staging", which puts the kernel in a placeholder until the next boot, at which point the kernel will be written to the correct spot. Because of this writing to the correct partition, you will notice a quick double-boot as the updated kernel is written to the correct point in firmware.
Code:
fastboot -i 0x03F0 flash staging "c:\fastboot-s7e\blob"
I hope this helps.
Oh and to those curious, the beats version appears incompatible with the standard s7e, I tried modifying a rom in the same way as above and it just went to a blank screen. My guess is they've done some form of sanity check in the kernel, given that every "beats" version I've read about in tablets has been a software-only modification. I've not bothered trying to use the beats version rom with the s7e kernel, I'll leave that for someone else to try in greater depth as I'm just happy that I got everything working again.
references:
Fastboot (previously this): This is a copy of the twrp/cwm roms as well as fastboot & adb taken from tegratools 2.2 mentioned above.
SignApk (Previously this): The java files and self signing certificate I used to sign the .zip file. It was actually a bit of a pain to find a working signapk.jar that had the valid certificates included, most were broken in one way or another when trying to sign on ubuntu 12.04.
slate7update-signed.zip (previously this): A signed copy of update.zip with META-INF\com\google\android\updater-script modified to remove the assert validation lines sanity checks, be careful with this, you could nuke your tablet if you use it on an incompatible bit of hardware.
guide.txt (previously this): A full how-to with a number of things I've omitted from this response.
To those wondering, I collated the above procedure from a dozen different links on a good four or five websites, including a number of threads here on XDA. Thank you to anyone out there that contributed to the information I found, you really made my day so much better in being able to recover my tablet.

I was able to unlock my bootloader using the above method and it worked. My s7e rebooted and everything was working normally. I loaded the bootloader again to go in and do a cache wipe and my 3 year old bumped into me as I was holding down the volume+ and power buttons. Now I'm stuck in ADX mode (black screen but recognized by my pc, have tried connecting to charger, volume+ and power, volume - and power, nothing works) . I've read that Advent has released adx files for the Vega Note 7 and you can use Tegra Note 7 Super Tools to restore the Nvidia Note 7. I'm wondering if I can use the update.zip file and the nvflash files from Nvidia to restore my tablet from ADX mode.
Any suggestions?
Mike-S, Thanks for the in depth how-to. I tried to sell my Extreme 4450 and the guy that I sold it to said when he received it was in boot loop. I got it back and it is indeed the one I sent him, however, now I have a bricked tab that doesn't even allow fastboot. I have, like others tried calling HP, tried installing per you instruction and finally considered just throwing away or selling. I almost seems like the recovery was wiped... I can get to uploading from SD and have tried using your info to accomplish with no success. Any suggestions? I hate to smash it or try and sell if I can fix it.
Thank you in advance for anyone's help

Damn, I'm sorry to say that I'm unsure if i'll be able to help much or at all. All i can suggest is look and see if there is any pre-boot subsystem that connects to your pc via usb, similar to the mediatek "preboot mt65xx" which can sort of provide a last gasp chance of recovery.
help with ROM
Hi there,
Need desperate help. I followed the instructions here but ended up with no OS in the s7e. I kept on trying to install a signed ROM via ADB, it reaches 100% senidng but always failed inside TWRP. Not succesful even with CWM. I even tried installing from SD card but no success. Please help, thank you.
Anyone still around here?
Mike S ... not sure you (or anyone else) is paying any attention to this thread anymore (and the HP Slate 7 Extreme at this point is a fairly old device) ... but I can't get any of these methods to work and my S7E (model 4450) is basically useless right now. When cold (i.e. not booted up in prior 30mins or so), I can boot it normally, but within about 10mins, it will "crash" to the all-white HP splash screen and will never recover. Holding the power button just has it go through initial startup, get to the white HP splash screen, and sit there until the battery runs down. I haven't been able to root it yet, so the bootloader still shows "locked". What's ironic is that this device is really all I need -- I don't play high-end games and mostly just stream shows -- but now it's completely unusable. I'm not sure which is easier ... trying to get this to root or just buying something else?
So far, to root, I've tried towelroot and Cydia Impactor, but both of those returned errors as others have reported. I tried following the steps that Mike S put up here, but without my tablet being rooted, adb and fastboot don't even detect my device from the PC (though the PC detects it because I'm able to see it in Windows Explorer and drag files to the storage) ... so it seems like I can't even get to install CWM or anything further.
Maybe the right thing to do is just to dump the paperweight ... it used to work so well but about 6 months ago this stupid HP white screen crash started happening, and since then it's become a regular thing that only takes about 10 mins (at most) before it craps out. I can get to the bootloader and onboard recovery mode, but that doesn't let me load anything.
Not sure where to go next but any advice would be appreciated!

Get your device drivers right (try androidsdk if it's still not getting recognised) and fastboot the stock system images (fastboot is not root dependent). By the way why were you trying those weird rooting methods ??? Just flash supersu from cwm/twrp and be done with it.
Thanks ... I'll try androidsdk. I actually am a root n00b and so I was trying to figure out the simplest way to go. I guess I guessed wrong! But of course before I can get that working I need the right drivers ... So I'll try that first. I was thinking the drivers were OK since my PC recognized the S7E when Android loaded (before it crashed to the white screen).
Couldn't get androidsdk to work
Hello again... I never could get androidsdk to work. My computer never recognized the tablet to be able to fastboot. *sigh* As much as I hate to give up, I don't know what else to do.... I might try another PC?

Hey Mike, you wouldn't still happen to have that signed update.zip since you've don't have it on Dropbox anymore?
So I recently grabbed me a Grouper recently to *cough* remember my first Android powerhouse (before I met the Optimus G) and decided to tinker with it as usual. I've owned 6 (now 7) different Groupers in this lifetime and have great experience with it, how to get those pesky drivers working, etc. This is my first 32GB model ever. Anyways, I unlocked the BL, rooted and flashed TWRP (thanks to WugFresh's toolkit) and decided to play with the newer roms (last time I owned one, KitKat was a rumor) and kernel combos. Anyways, I decided I prefer its stock performance and battery, and that maybe I'd use Xposed to tweak apperance instead. My mistake was, I should have flashed a flashable stock rom. But NOOOOO...I decided to flash it back to stock with the fastboot method (which we have various threads on, and toolkits including WugFresh's). Trying the manual method, I followed the following guide using a 4.4 image zip file:
http://forum.xda-developers.com/showthread.php?t=1907796
Claims that the sysem.img doesnt exist when it gets to that part. I extracted the entire file and it DOES exist. Anyways, I tried WugFresh's tk and sort of gives me the same ending (after literally almost an hour of waiting TWICE due to my old PC).
THERE WAS A GUIDE I SAW SOMEWHERE while Googling "how to" get back to stock on Google which actually point ou how to MANUALLY flash each .img yourself one by one via fastboot, which I really intended on doing instead of the above methods (DIY anyone?) but I can't find that guide and I'm not even sure if the post was here on XDA or Android Central. I should have done all Google search on the PC instead but ATM the tablet seemed more convenient for a search.
Anybody know the guide I am mentioning or know what I am talking about? I am assuming that method will solve my dilemma, and I like doing these things manually at times anyways....
EDIT: To my disappointment, found the post, but no good:
http://www.androidbeat.com/2013/11/flash-factory-image-nexus-device/
Apperantly everything flahes fine until it gets to the system.img part...adb/fastboot just freezes there and wont budge at all. Since I noticed that it did flash things, I've decided to flash TWRP and just flash a rom from my flash drive (thanks to a USB OTG) but I would still like to actually FIX the thing properly and return it 100% stock. Any ideas?

I'm not sure what you mean by stock. Are you trying to flash a "Stock" rom from the community or the stock images provided by google?
If you are using nakasi-ktu84p image, the flash script contains:
Code:
fastboot oem unlock
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-4.23.img
fastboot reboot-bootloader
sleep 10
fastboot -w update image-nakasi-ktu84p.zip
You can see here the exact process of getting back to stock.
The boot, cache, recovery, system, and userdata are erased.
Then an attempt to flash the bootloader. This will fail on nakasi-ktu84p and several images back.
Google has been negligent in addressing this issue.
I was able to find success with bootloader-grouper-4.23.img which I extracted from nakasi-krt16s.
You could save time and bandwidth from acquiring it here.
This bootloader also failed to flash for me!
If you have flashed a custom bootloader in the past, you may need to go all the way back to JDQ39 bootloader-grouper-4.18.img.
fastboot flash that, and then you will be able to flash 4.23 from krt16s.
Once you have passed this small ordeal you should be able to install the latest ROM.
In summary, you should be able to do the following from a system that has the fastboot binary:
Code:
EXTRACT nakasi-ktu84p-factory-76acdbe9.tgz
OVERWRITE bootloader-grouper-4.23.img with one acquired from krt16s
Code:
nakasi-ktu84p bootloader-grouper-4.23.img
MD5 = 5bdb2e87370cdb1a7ea14bb0c3e21390
krt16s bootloader-grouper-4.23.img
MD5 = df53028033c9eccf4fe5ba7bc198ce24
Code:
run flash-all.sh or flash-all.bat
PS.
I have been lured by the idea of stock stability, performance, and battery life. Something about Xposed seems dirty to me.
Battery life and Performance have always been better on a custom ROM / Kernel in my experience.
Stability can be rock solid when you've got a good system.
My favourite solution is to have the stock image installed and stripped down for size. This always you to boot in and update your apps from playstore.
I then install a custom ROM alongside via multiRom. This rom also has extras stripped out and no gapps installed.
From Rom 1 you can copy your apks into Rom 2 as needed.
I tend to avoid any apps that would be incompatible with this method!

I'm not sure what you mean by stock. Are you trying to flash a "Stock" rom from the community or the stock images provided by google?
If you are using nakasi-ktu84p image, the flash script contains:
Code:
fastboot oem unlock
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-4.23.img
fastboot reboot-bootloader
sleep 10
fastboot -w update image-nakasi-ktu84p.zip
You can see here the exact process of getting back to stock.
The boot, cache, recovery, system, and userdata are erased.
Then an attempt to flash the bootloader. This will fail on nakasi-ktu84p and several images back.

Your on the right track that's exactly what I was looking for, but to me it doesn't work on the system.img flashing part, it stays stuck there forever without a hint of movement at all. I left it flashing from 4am to 7am with no progress. I though it was working as the Windows Task Manager was showing fast boot constantly changing in CPU usage as it does when its at work. But sadly, it gets stuck there for good. Then closing fast boot won't work, I have to shut down the PC in order for it to leave

WugFresh is a toolkit made to root, unlock boot loader, relock, restore to stock, etc. And yeah I used the fastboot erase and fastboot flash commands via ADB/fast boot and as I said, everything goes well except the part where its time to flash the system.img, it just hangs there doing nothing. Tried and left it for several hours and still nothing
Try a different USB port on you computer or a different USB cable... or both.

Hi, Crossvxm...
This seems to be a relatively common problem, and I always seem to have it myself when fastboot flashing factory stock.
I've no idea why, but the fastboot connection seems to 'time-out' when fastboot flashing 'system.img'.
Now normally, and just prior to running any fastboot flash commands, you should run this command...
Code:
fastboot devices
This command doesn't actually do anything; it's essentially just diagnostic and is used to confirm you have a viable fastboot connection prior to flashing anything. If do you have a fastboot connection, you should see something like this (with the N7 booted into the bootloader)...
Code:
015d2d42xxxxxxxx fastboot
This is the Nexus 7's unique serial number followed by the word 'fastboot'. If you don't see this, then you likely have a driver problem...
...BUT HOWEVER, I KNOW I DON'T HAVE A DRIVER PROBLEM.. so when having problems with 'sending system', and upon opening a second command prompt window on my Windows laptop, and typing fastboot devices again, the Nexus 7's serial number now no longer appears... and this is AFTER the bootloader and boot img's have been sent and written successfully.
At this point, I can only conclude, and that for unknown reasons, my fastboot connection has 'died'... and 'sending system' is now permanently 'stuck'.
And the fastboot flash attempt has failed.
-----------------------------------------------------
The solution for me, was to change to a different USB port on my laptop. Another possibility might be to try a different USB cable... I haven't tried this... just a change of USB port on my laptop was sufficient, and the problem with flashing system.img was resolved.
Either way, reboot the N7's bootloader using a differerent USB port on your computer or a different USB cable... and attempt the flash again.
One final point... 'sending system' does take longer than the other .img's, probably due to it's size... but it really should take no longer than around 5 minutes... 10 minutes maximum.
Hope this helps... and good luck.
Rgrds,
Ged.
Tired of waiting for the OTA? Can't use it because you're rooted? Don't want to wipe your entire phone? No problem! Here's how you can upgrade with Google's Nexus factory images without wiping your apps or sdcard.
NOTE: You must have your bootloader unlocked. If you've never unlocked your bootloader, I don't think there's any way to do this without wiping your data.
STEP 1: Install fastboot
Fastboot is Google's utility for flashing factory images. You can also use it to flash custom recoveries like TWRP and CWM. The standard way to get is is through Google's Android SDK, but that's a bit heavy-duty, so you can also download just the most important tools (fastboot and adb) separately, packaged by users. Here are some links:
Official Google Android SDK (cross-platform): http://developer.android.com/sdk/index.html#Other[1]
Unofficial for Windows: http://developer.android.com/sdk/index.html#Other[2]
Unofficial Mac/Linux: http://code.google.com/p/adb-fastboot-install/[3]
Windows users might also need to install drivers: http://developer.android.com/sdk/win-usb.html[4] (can any Windows users confirm whether it's necessary?)
STEP 2: Prepare factory image
Download the latest Nexus 6 factory image at https://developers.google.com/android/nexus/images#shamu[5]
Unzip it and open the resulting folder
Unzip the "image-shamu-*.zip" file in there
You should now be looking at something like this: http://i.imgur.com/mzrfwrP.png [6]
STEP 3: Flash! (Ah-ahhhhh! [7] )
Connect your phone to your computer via USB, and enter the bootloader. You can enter the bootloader by holding down the power and volume-down buttons to boot. Once you see the bootloader, you can release the buttons.
Open a terminal/command prompt. The syntax might be slightly different on Windows than on Mac or Linux, but basically the same. Anything you see in <> you need to replace, e.g. with the actual path to your factory image folder. The rest you should be able to copy and paste. (Tip: you can easily enter a folder path into your terminal/command prompt by simply dragging the folder onto your terminal window. This works on Mac, Windows, and the vast majority of Linux GUIs.) Enter these commands:
cd </path/to/shamu-lmy47d>
fastboot flash bootloader bootloader-shamu-moto-apq8084-71.08.img
Reboot the bootloader.
fastboot flash radio radio-shamu-d4.0-9625-02.95.img
cd <image-shamu-lmy47d>
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash system system.img
If you DO NOT use a custom recovery (like TWRP or CWM), then also: fastboot flash recovery recovery.img
Don't worry if you see messages like "target reported max download size of 1073741824 bytes". Just wait and let it finish.
Reboot your phone and enjoy. It's normal for the first boot to take a while. Going from Kitkat to Lollipop took about 20 minutes. Going from 5.0 to 5.0.1 took 5-10, I think. YMMV.
A WORD OF WARNING: If you're moving between ROMs, you generally should do a complete reset, including wiping data. Many users have reported problems going from KitKat to Lollipop without wiping data and recommend a factory reset anyway. If you're okay with wiping everything, you can simply use Google's included flash-all scripts, or flash the userdata.img file yourself. Personally, I'm not going to bother wiping adta for an incremental update like 5.0.1->5.1. As always, be sure to back up your data!

Shouldn't you also fastboot reboot bootloader after radio flash?
This is the scenic route.
I tried to update using wugz, without unlocking the bootloader. failed. Oh well, I'll wait to receive ota
Unless this method doesnt require unlocking?
If you have an OTA zip file, this is different than using a System Img?
I do not think you need to lose data or unlock your bootloader?
Found a link for the OTA zip file.
If I remember right you can copy the zip to you phone with a USB cable.
Go into the bootloader, Volume Down and Power.
Select the zip.
I did not think you needed a terminal and all the commands if you had the OTA zip on your phones SD card.
Am I wrong does something like this not work?
or
I can just wait.....
This worked great.
I was unbranded with VZ sim, unlocked, rooted with TWRP recovery. Didn't want to lose all that nor my apps or data. This method upgrades to 5.1 without any loss.
When I was done with the flashing, I rebooted to TWRP recovery (not system) in order to wipe dalvik and cache (just to be certain). I wiped and then rebooted to system. TWRP noticed I didn't have SuperSU installed so it installed it for me. Meaning, once I got my system rebooted, I still had root too.
All in all, this process worked great for me. Thanks.
I run the first two commands
fastboot flash bootloader bootloader-shamu-moto-apq8084-71.08.img
fastboot reboot-bootloader
they worked, then i moved to the radio
fastboot flash radio radio-shamu-d4.0-9625-02.95.img
but it failed.
Any idea?

Why the failed message?
I'm decrypted. Will this re encrypt my Nexus or do I have to flash a non enforce img?
Thank you, this really helped.
Since my bootloader was locked i had to unlock it as well.
Had a bit of a scare with the whole erasing screen staying on for too long.
Went back and redid the process, and went downstairs for 5 minutes, came back and phone was booted.
Anyway, thank you again

I don't suggest that anyone read and follow someone else's instructions when doing something like this. Not because the instructions are wrong or anything, but because blindly following instructions doesn't involve *understanding* anything.
So rather than reading and following instructions, read and UNDERSTAND the process of installing factory images as delivered with the factory images (flash-all.sh). If you UNDERSTAND the process and what everything does, then (a) you *already know* what needs to be adjusted to do what you want, and (b) if something starts going wrong in the middle of it, you will understand why, and what to do to correct it.

First, thanks for the write up, I do greatly appreciate it. Second, thanks for the tip on dragging file locations into the command prompt. Very helpful.
Now my question. When I did this I tried using exactly the steps above and had no luck whatsoever. I'd cd to the location of the img files as noted and it would say fastboot is unrecognized as an internal or external command. I moved the file into the fastboot location and got the same issue. I finally ran the fastboot from the adb folder location and just referenced the full file path for each img file (using the drag and drop method) and everything went swimmingly. My question is just about using fastboot. Should it have worked when I used cd to go to the img file location? Is there something I need to do to make it work as you described?
Thanks!

Install this:
http://forum.xda-developers.com/showthread.php?t=2588979
Now ADB and fastboot are installed system wide. Put your files anywhere, I use the desktop. Hold shift and right click on wherever your files are and select "open command prompt here" and flash away. Simplified, no more dragging and dropping.
Will try with the new update (5.1.1 (LMY48M)) to ensure it works. Thanks!

Have been flashing this zip in twrp after the fastboot stage without an issue for the last few updates - http://forum.xda-developers.com/nexus-6/development/mod-disable-force-encryption-rom-kernel-t3000788
Flashed LMY48M with fastboot method and it works great.
My phone is encrypted.
[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.

Shouldn't this step be
Code:
adb sideload f69096766706fab3c721163f02aad9073a989d00.unsigned-shamu-LYZ28E-from-LMY47M-fullradio-fix-superblock-use-TWRP.zip
instead of fastboot flash?
So if your starting out with 47E, your rooted and have TWRP ..... would you use adb sideload in TWRP or you issue the command from the PC?

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

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.
EDIT: Fixed, see below.
Hello all, I have a Pixel 4 running the July build of Android (QQ3A.200705.002). I previously had it rooted with Magisk, but I have reset the phone and it's not longer rooted (verified; originally it was still rooted after a factory reset) .When I attempt to relock the bootloader, I type the command
Code:
fastboot flashing lock
However, fastboot just shows me the help message, as if I were to type 'fastboot help'.
When I try to manually flash an image using flash-all.bat (QQ3A.200705.002 for example), I get the following error:
Code:
error: failed to load 'image-flame-qq3a.200705.002.zip': Not enough space
If I try to manually flash individual images, I get various errors. For the boot image, I get an error that says no partition exists (like my boot_a slot isn't there. I can flash it into boot_b just fine). If I try to flash system, it tells me I need to be in fastbootd; I haven't looked up how to do that yet. I am a bit lost here, I've never had anything like this happen before, and the system is completely wiped from a factory reset, so there is plenty of available storage.
I figured out that I was able to update to the August build (QQ3A.200805.001) by sideloading the OTA update, but I still cannot lock the bootloader. This is what happens when I run the command (reference Fastboot 1.png).
I also tried it in Powershell ISE, and I'm getting this error (reference Fastboot 2.png)
Code:
+ FullyQualifiedErrorId : NativeCommandError
Almost like fastboot itself isn't recognizing the 'flashing' command.
Thoughts?
I was able to fix it by downloading the latest platform-tools from here: https://developer.android.com/studio/releases/platform-tools
However, I am pretty sure I was already on the latest platform-tools (I had flashed the phone numerous times on Android 10 already), but I digress.
