First time poster, but thought I'd share how I managed to fix my problem, in hope that it helps someone else out.
I recently received the OTA Marshmallow update for my Stock Nexus 9 (unrooted and locked bootloader), but unfortunately it didn't work, and threw me into "bootloop" where it continually tried to apply the update but failed. First off I followed instructions to clear the Cache, which only made the problem worse, as all the tablet would do then was boot into the “swirling colour dots” and do nothing else until eventually the battery died.
After reading several forum posts I discovered that the usual solution is to flash via fastboot, however on a Nexus 9 you need to unlock the bootloader by activating "Enable OEM Unlock" from within Android. As I'm running a 100% Stock Nexus 9 I had never done this, so couldn't flash it.
Eventually though, after having an absolute nightmare trying to get it to work again, I found a working solution! Just use "Apply update from ADB" under Recovery, along with the correct update image!
A lot of what's in the steps below is likely to be known to most of the community, but I’ve tried to keep the steps extra simple so anyone can pick this up.
Steps:
1. Reboot into HBOOT (Hold down Volume Down + Power Button).
2. Press Volume Down to highlight Recovery, then press the Power Button to enter it.
3. Wait until the Google logo goes away, and you should see a picture of an Android laying on it’s back. Hold down the Power Button + Volume Up (very important to hold Power FIRST).
4. On the Recovery page it lists a few details about your version at the top. Note down the 6 character identifier for your device (which is in the format of 3 text characters, 2 numeric, and another text char). For me I was running 5.1.1 before the update, so my identifier was LMY48T.
5. Find the OTA update that upgrades from your current version to the next version. For me I was going from 5.1.1 to 6.0.0 on a Nexus 9, so I searched for LMY48T on Google and found that this was the OTA update needed: https://android.googleapis.com/pack...83199e.signed-volantis-MRA58K-from-LMY48T.zip
6. If you don’t have it already, download and install “Minimal ADB and Fastboot”: http://forum.xda-developers.com/showthread.php?t=2317790 – when it’s installed let it run straight away, and leave the command prompt open you’ll need it in a min.
7. If you don’t have it already, download and unzip the Google USB Driver: https://dl-ssl.google.com//android/repository/latest_usb_driver_windows.zip
8. Copy the OTA update file you downloaded to the folder that Minimal ADB was installed in (usually C:\Program Files (x86)\Minimal ADB and Fastboot\).
9. Back on your device use Volume down to get to “Wipe Cache Partition”, and press the Power Button to activate it. If you want to be really sure this will work you should do a “Wipe data/factory reset” too, but be aware you will definitely lose your data.
10. Use Volume up to go to “Apply update from ADB”, and press the Power Button to enter it.
11. Plug your tablet into your PC (if it’s not already). You’ll need to go to your Device settings on your PC and you should see a new device named the same as your device or possibly just “Android”. Go to the Properties of the device and force the Driver to be the ADB Google driver from the Google USB Drivers that you downloaded earlier. (There’s plenty of other longer tutorials on how to do this if you’re having issues)
12. On your PC, in the Minimal ADB Command Prompt (that you should still have open from earlier) enter “adb sideload {NAMEOFOTAFILE}” e.g. for me this was “adb sideload ab835e17c874202049463ccd916f86fede83199e.signed-volantis-MRA58K-from-LMY48T.zip”.
13. Let it run. It took less than half hour for it to install for me, and I’m now the proud owner of a working Stock Nexus 9 with Marshmallow!
So why does this work but applying the stock images via fastboot doesn’t? As far as I can see it must be due to the “signing” of the files. The regular stock Google fastboot flash images don’t include signature information (as far as I’m aware) so they’re rejected as unsafe by the locked bootloader, whereas when you run the OTA update files through ADB sideloading signatures are on the OTA update files, and your device determines that these are safe to install.
Yeah, as long as your system partition is intact, "adb sideload" is a good option. I'm not so lucky...
nothint to do with mine, it doesn't show any OS versione unfortunately.
works well
Hi,
I had exactly the same upgrade failure, despite of a clean stock Nexus 9.
I followed the procedure and it works great for me.
Thank you for this post !
FYI - You don't need to go searching for OTA files on Google. They're all conveniently posted here:

Ok, so I found where mine said lmy48i. I downloaded the upgrade file a8f87fa059f17f2fd4cd773921e888366b1dfa0e.signed-volantis-LMY48M-from-LMY48I.a8f87fa0.zip. When adb starts sending it, it gets to about 48% and the tablet starts verifying already. It winds up erroring out with the following information:
************
system partition has unexpected contents
E:Error in /sideload/package.zip
(Status 7)
Installation aborted.

Any thoughts?

The same situation, maybe have any other solutions?
I wound up calling HTC and getting an return authorization. I have to pay shipping to them. They cover shipping back to me. But the whole thing is going to wind up taking about 2 weeks. Couple days to get there, 7-10 days to fix, couple back. I haven't sent it out yet. I bought mine at BestBuy, so I was going to see if I could swap it out there first.
Josh
it doesnt show any OS version either, what can i do?
Guide works perfectly. Massive thanks.
The trick is finding the latest OTA zip. Here for the moment.

I got it to work but I'm never buying another HTC product again. I called warranty service in the first guy refused to help me out unless I had the tablet in front of me. The second guy did help me but I'm still waiting for the RMA ticket, it still has not showed up. So when I got these instructions I managed to resurrect for my Nexus 9 which is good. Now I have a working tablet to which I'm talking to the right now, but other than that HTC still sucks ass and I'm never going to buy anything from them again. Done.
I am on MRA58N currently facing the same issue. I downloaded the MMB29K update. But on running the sideload, I am getting the message
"E: Footer is wrong
E: Signature Verification Failed
Installation Aborted"
Pls tell how to proceed

By some miracle or so, my device has come out of the bootloop and is working fine now. But it is giving me this error (link below), before the boot up begins.

Looks like the OTA corrupted something.
Note: OTA updates only work on completely stock devices.
Backup your devices important data.
If you where completely stock without unlocked bootloader, you will need to flash stock images to get rid of that message (OEM Unlock Command will wipe your device)

I did a stock image flash using the Nexus Root Toolkit. But the message is still appearing whenever I restart the device. Otherwise the device is working perfectly.
When I get to step 4, I don't see device identifier text. I got text in pink saying
Code:
" *** Device state - LOCKED *** "
What do I do now
Just got it back from 'repair' via HTC, if anything it's got worse, with random freezes, lock screen freeze and bootloop.
Marshmallow OTA hose your Nexus device? Just flash the N dev preview.

Posting the above for anyone with a Bricked device from a previous Marshmallow OTA and where not able to resolve it by sideloading a Marshmallow OTA.
Many Thanks!!!!

I wanted to thank you for posting this solution!! I was able to flash N onto my nexus 9 and it is working once again. I was going to post this onto a main thread so that more people can see this but i did not want to seem as if i was taking credit for finding this. You should post this there so that you can help others. Once again, I would like to thank you. I am now trying to get into the usb debugging menu to unlock the bootloader so this does not happen again but i cannot find it in this version of android.
MANY THANKS!!!

1. Share the link where you like, the Original Finder of this is mentioned in the link
Posted here
2. Have you enabled developer options? Or does Android N not have that feature.
Found the developer options!!
Thanks and yes I found it. I had to reboot my tablet to see the Android version. It must be a bug but I will be happy to deal with a small bug like that. Much better than a bricked tablet. The first thing I did was to enable unlocking of the bootloader in case this happens again. Fool me once but not twice..lol
Hi all, I am stuck.
I got my Mate 10 Pro (BLA-L29) and wanted to install LinageOS 15. I followed the guide here, rooting and everything went fine. I installed LinageOS 15, the most current build then, via fastboot flash system systemXXX.img. The process went well, the phone rebooted. But since then its stuck in eRecovery Mode. It offered me the "factory wipe" option on the first time, since then I get the options of Rescue (which times out or can't find the files), Shutdown and reboot. It also shows a "this device is not to be trusted" splashscreen during boot, including a link that leads to a 404 on the EMUI-OS-Site. Sorry if that has been asked already i did not find much regarding eRecovery.
I managed to install TWRP, but strangely it still boots into eRecovery. I can force it to boot into TWRP, but it simply will not switch away from eRecovery.
So, what are my options?
1) wait and see, try new versions of LinageOS.
2) use the firmware finder to get the original firmware (any pointers about which one? I'd go for the earliest 8.0 for the BLA-L29?) But how can I get it to the phone since its not an image and the phone does not have a SD-Card? Can I mount it via USB?
3) Get rid of eRecovery or force a switch to TWRP - is that doable?
Any help would be greatly appreciated. I did a lot of custom firmware back when I had the first Desire, but since then I used Blackberry or other, non-rooted devices. I want my control over my OS back.
Thank you in advance, let me know if you need any more information.
Ok, if anyone else needs help:
This helped me, I got back to the Mate 10 Pro Stock ROM
https://forum.xda-developers.com/mate-10/how-to/root-updates-rebranding-unbricking-t3701970
Important: after flashing, you need to remove the USB-cable, otherwise it will just boot into recovery
Firstly, let me quickly outline what I have done.
Unlocked bootloader
Installed TWRP
Installed a ROM. I wasn't happy with it. It was rooted which of course my banking app didn't like. hideSU didn't work, I couldn't remove root so I tried another ROM.
Once installed I reboot and I have stuck in this loop ever since. I cannot get into TWRP. I've gone into fastboot mode multiple times and tried over and over to install TWRP and reboot into it but nothing.
Worse still is the erecovery option to download latest version over wifi just doesn't work, "Getting package info failed".
Another "useful" Huawei feature if the ability to hold vol up and down to auto install a firmware image. Not helpful when I have no ability to put any files on the device in these modes.
Finally, I have no idea what exact version of firmware I need to download. All I know it is a P20 lite and I bought it from the UK.
Can anyone help? I'm literally staring at this brick stuck in eRecovery.
your try to use hwOTA8, this installs 100% all the firmware (I had the same problem as yours).
nm
Never knew that existed so thanks.
I thought I was finally on the right track but it seems my phone is different from every other one.
I used HWOTA8 and it wants to install TWRP right away. I followed the video instructions and mimicked his movements exactly and when his reboots into TWRP mine does not.
UGH
Hello, I am new here and I made a huge mistake!
I purchased Samsung Galaxy Tab S6 Lite (LTE) literarally 1-2 days ago and I wanted to root it, I had my smart phone rooted which did not have Knox protections, it was as straight forward as flashing TWRP and use Magisk via instructions I followed.
I make use of "Root" privileges a lot when using my device, I find it very important to my daily life so I decided to risk rooting it, after doing so my tablet was showing 2 errors, that its not using official samsung software and that the boot loader is unlocked, when I unlocked the boot loader using OEM Unlock everything went fine, the option was greyed out and checked afterwards.
During the boot process, it reboots 2 times and it shows a integrity error, integrity and some very long number, I am assuming its a integrity check? I have the exact matching firmware, so I flashed back the stock firmware and... the "not using official samsung software" warning disappeared, it boots me into recovery mode, I choose "reboot" and the device goes to boot looping with the same error.
I was following this tutorial: https://forum.xda-developers.com/galaxy-tab-s6-lite/how-to/howto-unlock-root-galaxy-tab-s6-lite-t4132289
But there are some things I skipped, here the exact steps I took:
Unlocking Boot Loader:
Followed all the steps from 1 to 4 but I skipped the 5th step entirely, the step where it asks you to mess with firmware date and twrp, I did none of that, I will mention that when I was looking for stock firmware to download before doing anything, I was not able to understand the CSC so I didn't know which firmware to exactly use until a software update came up which told me the exact firmware, I accepted the update and download that stock firmware, because my firmware was updated I didn't think that following the few steps of the step 5 would've done everything as I was already off the path.
I didn't do the 6th step as I just checked of the OEM Unlock is greyed out and still checked in the "developer options" section, I assumed that it was a success, not to mention the boot loader unlocked warning that was showing up and yes, all the data was erased and was forced to go through the setup process again as expected.
Root the tablet:
1. I have downloaded the firmware as it says not just for the purpose of rooting, the firmware that the software update told me about, this is the firmware I downloaded, the firmware is a exact match, everything is matching: https://samfrew.com/download/Galaxy__Tab__S6__Lite__-LTE-__/xs5l/SEB/P615XXU3BTI3/P615OXM3BTI3/
2. I follow all the steps from 2 to 11 from here.
3. When I reached step 12, I went to download mode and I look for any messages regarding it only allowing for official samsung images, but I saw no such message, didn't really pay attention to anything else, I just glossed over things, considering there was no such message I assumed that KG/RMM state was good, don't know what it was but it might not have been "prenormal" because there was no message regarding official samsung images, from here I falshed the boot.tar file like in the instructions, that lead me to my current problem I mentioned at the very start of this post.
4. There was no step 13 as I can't boot into android due to "integrity" error I have, right now I have my tablet turned off (thank god I can do that) via the recovery that shows up after flashing stock firmware.
Addition Info:
1. I don't have any data to lose, if I need to do a factory reset or something of that sort, I have no problems doing that.
2. As I mentioned at top, I do have a stock firmware downloaded from this link here: https://samfrew.com/download/Galaxy__Tab__S6__Lite__-LTE-__/xs5l/SEB/P615XXU3BTI3/P615OXM3BTI3/
3. The tablet is: SM-P615 (Samsung Galaxy Tab S6 Lite (LTE), I bought the LTE so I could use it as my phone)
4. At the download mode, the OEM (Boot Loader) state is set to NO and the FFS (I don't remember if its FFS exactly at the moment, something FF I believe, I don't want to turn on my tablet at the moment) was set to NO.
5. The KG (No RMM mention that I could see anywhere) state is showing up as "Checking..."
What do I need to do to fix my tablet? do I need to wait for 7 days? if so how do I do so, like does leaving my tablet off count or not?
PS: I am a self-thought experienced low-level windows programmer, I've been doing programming for over 10 years now, never have worked with Android development but I can attempt to build something from source if necesarry, I know very little about Linux OS as I purely work with Windows and use Windows for everything including servers.
I have done some research regarding that "integrity" error and I can't find any screenshot in google images that matches how it looks on my screen, but there are a lot of them quite similar to it, which basically says "verification failed, factory data reset your phone", in my case I don't have that message, it just says "integrity", but when the boot looping stops and shows that failure I do have 3 options, "try again" and "Factory data reset" and the 3th one I don't remember, I am suspecting that this could be my problem! I believe the samsung just changed the way that particular message is shown (visual change), so I just need a factory data reset and it will work, most likely with the rooted boot.img file! I will attempt this after a few hours of this reply, I may have panicked too early.
The issue has been fixed
Well this is surprising, I was about to do the factory reset but before doing so I decided to flash the same magisk patched boot.img file, when I flashed I saw seeing those 2 warning messages as expected, I was expecting for it to fail after 2 boot loops so I can do the factory reset as intended but on the 3th boot loop the tablet booted up! I was brought at the android setup screen, once I was done with that I checked the OEM Unlock, it was still checked and greyed out, downloaded Magisk Manager and to my surprised it worked! Magisk Root latest version is installed and working, it asked me to allow magisk do some "additional setup", the tablet booted up perfectly fine after that "additional setup", I check root privileges using "Root Checker" and it worked, I have root privileges! I most likely have panicked too soon, sorry for wasting your time! Hopefully this post will be useful to someone in the future looking to root their tablet.
My assumption of what happened: When I flashed the stock firmware AP a second time so I can turn off my tablet, it most likely did a factory reset without me knowing, so when I flashed magisk again before letting it try boot up again, the tablet booted perfectly fine because factory reset has already occured, which brought me to the android setup screen.
Hello,
The last week or so I have been trying to flash TWRP onto my Samsung Galaxy A40 (SM-A405FN) to install LineageOS. However, as I started following different guides and methods I have run into several problems that I can't get around and I was wondering if anyone here has had a similar experience or knows the solution.
The first problem I ran into was that when trying to flash onto the phone, neither ADB nor Fastboot detected the phone in download mode (when it was turned on normally they did). I tried various things to solve it: uninstalling and reinstalling different drivers, trying to find the device in device manager (it wasn't there) and nothing worked. I got around it, however, using Odin to flash. Odin did recognize the phone. I had already unlocked the bootloader and made sure VaultKeeper didn't lock it again. I believe it is fully unlocked now, I have even waited the week period to remove the RMM thing (I'm not entirely sure what it is and if I've done it properly, it's been a while since I've messed with android, but it used to display "KG state: checking" and now it's gone).
So, with Odin recognizing the phone I tried to flash the official TWRP recovery for it, following the instructions on the website. However, after flashing it, the phone bricks and boots into download mode all the time, with the error "Error validating footer (6)" on the top left corner. I have googled far and wide and the only solution I find is to reflash the stock ROM. Of course, this works, but I would like to be able to install LineageOS on the phone.
Thank you for in advance and let me know if you need more information or pictures of some sort.

Hello,
You can try the tuto on the following link:
It's for samsung A20, but you can apply the same practice for the samsung A40.
The first part of this tuto is woking for me (TWRP) but not the last one: "Rmm bypass"
