No you can't take an OTA if you have any modifications to /system (root). Have a look at my guide:

I got an 8MB update for the november patch. Being on TWRP and root i need to convert back to stock before i can have it leave me alone? Is there a way to flash the patch without doing that?
Thanks for answering my question

No way around it, any modifications will cause the update to fail.

@amoeller had me flash the modified boot.img for MDB08M then flash the MDB08M system.img and vendor.img from the factory image. I rebooted bootloader, the booted to TWRP and re-flashed supersu. I am now on the November patch without having to remove TWRP and all works well. My user data was also untouched.

User data should never be affected during an OTA anyway.
This is actually the first time I've unlocked a phones bootloader and stuck with the stock rom. I usually use some kind of popular rom with it's own built in OTA (CM/Viper One)
How often do you guys actually update your phones for OTA? It seems like a real hassle

I am rooted now so I'll wait a while before updating an ota until there's a big deal of info. However, in the past if I was sticking with stock there's usually at least one developer who posts the updates with root and stuff built in so you can easily flash with twrp. So I'm kind of waiting for that. That or cataclysm or another awesome rom that's close to stock.

I wait for factory image for that build and flash over the new images when they become available (provided that root can still be achieved). Some will do a clean wipe and start fresh with the new build and reload in their apps and user data, others will just dirty flash the updated system (and boot/bootloader or whatever else was changed too).
If you think about it, it really isn't all that different from taking an OTA, the difference is that we're applying the commands to flash instead of having it automated. It's not that big of a trade off in my book.
I have 2 questions...
What is the easiest way to make flashing updates a breeze if I have mods in /system partition? I have heard of "freezing" them. Or is the only option... to delete every mod and flash updates? If so, should I keep a note of every change I make to/system?
And last... Should I make a backup of any file i am replacing or overwriting in /system? And if so, do I have to put them back how they were before flashing an update?

If you're rooted then you need to download the full factory image, extract system and vendor and flash those. Reflash SuperSU.

It’s probably easier and quicker just to flash stock factory images separately instead of having to jump through hoops with OTAs. Like I told @roughriduz just flash the updated partition(s) that were updated like system.img, vendor.img, or whatever and just flash SuperSU in TWRP after.
The steps @roughriduz took was
1. Download and extract latest factory image.
2. Download matching modified boot.img for that build (For example MDB08M).
3. Flash system, vendor, and any other partitions (like radios, etc) with fastboot if they were updated in the OTA. Don’t bother to flash stock recovery because we’re not using an OTA. Flashing userdata.img is just like a factory reset.
4. Boot directly into TWRP and flash SuperSU.
5. Reboot and profit.
This method gives you the latest stock build rooted with TWRP while keeping your data because I hate having to redo my phone.

A couple questions:
1. Step 1 refers to the latest factory image that contains the update, correct?
2. Step two refers to the boot.img that contains root?
3. At what point in this process do you flash the modified boot.img, before or after applying the other images?
Thanks for your help!

1. Latest factory image is the latest factory image from the nexus factory images page. It's not an update like ota, but rather the entire image they would return you to stock if all is flashed.
2. Flashing a modified boot does not give you root. You still have to flash SU, so saying the modified boot contains root isn't right.
3. I flash boot first unless there is an updated bootloader.

1. This can be whatever the latest factory image is at the moment. It’s currently MDB08M. All the OTA does is update your phone to whatever build it was made for. Factory images already have previously released updates built into them. You can upgrade but avoid downgrading unless you want to factory reset your phone.
2. I’m referring to the boot.img without root by @mrRobinson found https://www.androidfilehost.com/?fid=24269982086992320 although this process can be used for systemless root also. For systemless root you wouldn’t flash SuperSU in TWRP but instead sideload the SuperSU APK as per Chainfire’s instructions and use the matching systemless root boot.img
3. I don’t think it matters but as long as you have the matching modified boot.img with the system.img installed before you restart, you should be fine.

What the heck did I do wrong here? I just tried to apply the November OTA update to my MBD08K build, it didn't work, and now I am in the process of doing a full reset and rebuild of my phone (flash-all of factory images from Google)
Here are the notes I made as I attempted to follow the procedure in this thread:
Code:
- Download latest build for MBD08K from https://developers.google.com/android/nexus/images?hl=en
- Extract boot.img, system.img, vendor.img to C:\adb (or wherever where adb and fastboot are
installed). You have to
- Right-click, open command window here
- Ensure USB debugging is enabled on phone (grant permissions on phone if you get the popup)
- In command prompt, "adb devices"
- Should see serial number and "device"
- type "adb reboot bootloader"
- Should get to bootloader screen with little android man lying down with hatch open
- type "fastboot devices" - should see your serial # again and "fastboot" beside it.
- type "fastboot flash boot boot.img"
- type "fastboot flash system system.img"
- type "fastboot flash vendor vendor.img"
- Use volume keys to boot into recovery (in my case TWRP)
- Swipe to allow modifications
- Install -> SuperSU.zip that you should have on your phone from last time.
- Reboot system
I saw a red "your phone is corrupt" scary message on startup... took a while to boot. Couldn't get past the dancing circles.
Interrupted boot, rebooted to fastboot, tried to flash old modified boot.img
Booted again, got encryption unsuccessful warning
Flashed most recent boot.img again, stuck booting forever
try again:
- flash system.img
- flash vendor.img
- flash boot.img (modified)
reboot to recovery - your device can't be checked for corruption (yellow warning instead of red)
- swipe to allow modifications
- reboot with TWRP, swipe to install SuperSU
- Encryption unsuccessful. Prompt to factory reset. Click OK. Boots through TWRP.
Give up, start flashing factory images.
EDIT: I might be the stupidest person alive. I think I should have been using the files for MDB08M. Arggghhhh. Someone please confirm I am an idiot.
Edit 2: Factory reset worked, I am at MDB08M. Now rooting again... grr. At least I backed up all my apps & settings to Google Drive with TB.
Edit 3: Rooted and restoring all apps with TB. If anyone has any insight into where I F'ed up I'd appreciate it.
Hi all,
I got a brand new Wileyfox Storm which I liked to have rooted. When I booted the phone I got several updates which I installed first.
After updating I followed this guide: http://forum.xda-developers.com/wileyfox-storm/general/root-wileyfox-storm-t3250992
And also with a little bit help from the Cyanogen wiki: https://wiki.cyanogenmod.org/w/Install_CM_for_kipper
Reason I chose for this method is because I tried the recommended WinDroid Toolkit before but the server doesn't has the required files anymore so that program is useless for the Wileyfox Storm.
I'm running Cyanogen Os version 13.1.2-ZNH2KAS3NA-kipper btw (offical FOTA).
When I followed Bobslesbricoleurs tutorial to unlock the bootloader I got a message but not one I expected. It said:
<bootloader> Device already : unlocked !
OKAY [ 0.000s]
finished. total time : 0.000s
Does this mean I got my Wileyfox Storm with bootloader already unlocked? That how I read it...
I continued to start rooting it, but not before testing if I could still boot but everything was fine.
I tried to flash the attached custom recovery I got OK and a 'remote: size too large' error. It didn't successful flashed the recovery.
I checked if everything still was ok and it was. I could boot and everything.
So I tried something different. I'm not new to flashing (I've had a Galaxy S2 for 5 years which was running on CM13) so I went to the Cyanogen site and downloaded the latest stable (snapshot) recovery for kipper which was cm-13.0-20160820-SNAPSHOT-ZNH5YAO0J4-kipper-recovery.img.
I tried to flash that recovery and it succeeded. I could still boot recovery and system... except that after booting system the ROM would replace the recovery back to stock.
I did some research on this but I couldn't find any helpful information about it for the Storm device. So I Googled it in general and read somewhere that COS had a developers toggle to disable 'updating recovery'.
This is probably where I made my mistake because I unchecked that update recovery toggle and reflashed the snapshot recovery that worked before.
I'm not very sure, I should have written this down, but if I remember correctly the system could still boot.
I didn't know how to flash the SuperSu-v2.46_signed.zip with fastboot, the tutorial didn't specify this and I'm used to flashing from recovery (fastboot is kinda new to me, although I have worked with adb commands before).
So I booted the rom, installed AirDroid to push the zip to my internal storage and I went back to the recovery.
I flashed the SuperSu-v2.46_signed.zip with the update option in the recovery.
And now the rom is in a boot loop.
I already tried a full factory reset but it's still boot looping.
I know that in the tutorial topic FluffyTwit has had a similar problem, not sure if it's the same but it looks like it.
The given solution is "Flash stock boot.img from stock rom zip, reboot" to which he replied " flashed the whole .zip file because I saw a tutorial on some website...".
But at this stage I'm a bit afraid that I'll do it wrong again, as the instructions are either out-dated or they're just not 100% correct. Could someone help me out and/or confirm the exact steps I should do to get my device back up and running?
I'd rather keep the device stock without root than rooting it with risks of bricking. I have a feeling this device isn't as safe to rooting as I'm used to..
Thank you in advance.
Edit: I've found my solution and had to change something.

Can someone walk me through how to Unlock the bootloader, root, and install TWRP? I'm so confused. I tried to do the newbie way, even though I'm not a newbie, and I lost my B29 Stock Recovery and can't find the download for it.
Sent from my ZTE A2017U using Tapatalk
I haven't done it yet but I've done a lot of reading and this seems to me the best guide.
Head over to this link which is the TWRP thread. https://forum.xda-developers.com/axon-7/development/recovery-official-twrp-zte-axon-7-t3515715
Once you're in there go to bootloader unlock section. Download all the necessary files and on the bottom of the guide there will be instructions link which will take you here https://build.nethunter.com/misc/axon7/INSTRUCTIONS.txt
Follow that and that should do it.
When i get a weekend off ill be using this method to get the Lineage OS 14.1 on my device.
Search, Read & Follow --CAREFULLY--.
It's been a while, but this worked great for me, starting from B29.
Goodluck
Let me tell you, this is the guide that should be pinned. It gives very easy/clear instructions on what you need to do to root/flash recovery and even going back to stock. Very well written and I wish I had seen it sooner. I was going to write a clear guide on this subject only to find.. it already existed.. --nolimit78
@amphi66 I am on 2017U B29 and want to unlock bootloader, install TWRP and root. I also read newbies thread. I am confused about one thing. which TWRP recovery image should I use? a2017u B27 http://d-h.st/kRgq or TWRP recovery 3.0.2-2 : http://d-h.st/dgWW ? There is no file for B29 on newbie's thread and in FAQ, the OP said B27 should work for B29. Which one did you use?
After reading, I also see some people said tenfar's tool is too dangerous and it may brick your phone. Some people also claimed the back up of TWRP recovery 3.0.2 provided on that thread has some bugs may cause you to loose your IMEI number when you do recovering. Do you have any issues? Thanks!

This was back last Nov, but I followed the guide, using the recommended files (was on B29, but used the B27 OK, then reflashed B29 at the end).
The warning involved backing up and then restoring the EFS partiton with tenfar's tool. DON'T! If you stick with system, data, and boot partitions you should be fine.
Good luck. You may want to check with @nolimit78. He has done this much more recently.
Yes, I agree with you @amphi66 that there is a lot of different places to get information about how to root/flash recovery for A2017U B29. Here's what I've done with two different A7's and both have worked each time.
1. Boot the phone to EDL Mode (Both Vol+Power on boot it'll quick flash the red notification light and then act like it's off.. it's not)
2. Use tenfar's tool to flash the recovery. (I renamed the updated TWRP img and named it "recovery". This used tenfar's tool to flash the updated TWRP on your device.
3. Once in TWRP, run the command (reboot disemmcwp and relaunch TWRP) and flash the package to use modifiable bootloader from B20.
4. Once that flashes now you can send the command in Fastboot "fastboot oem unlock" which will unlock the bootloader that doesn't trip anything notifying ZTE
5. At this point you can flash a B29 rom and have a grand ol' time. However, I would recommend using the LineageOS Rom that's available. Trumps everything else out there IMHO.
6. To do that You'll need to flash the Nougat Bootstacks for that rom to boot prior to flashing the Rom itself. I would recommend flashing the nougat bootstacks, reboot to TWRP, flash LineageOS, reboot.
Like I said, I've done with this with two different devices (Thanks ZTE) and both worked out just fine. I did this method with a device with b27 and b29, both ended up updated and flashed with CM/LineageOS with ZERO issues. This post here should also be pinned as the one true guide (THE KING OF THE NORTH) for unlocking/rooting a stock Axon 7. I spent probably about 4-5 hours working, trying to figure out how to get my device unlocked/rooted. However.. at the very end I wrote out instructions trying to help those who would come after me.. I searched the threads to make sure there wasn't already a thread out there.. and then.. it turns out there was.

Hi all, I posted this in the 6P bootloop thread, but didn't get a response. As that is a pretty LONG thread, i'm thinking my question may have gotten lost in the jumble.
Quick run down.
A few months back my 6P started the BLOD. I found the fix listed on these pages, applied it, and have been happily using my phone ever since. Phone is bone stock 7.1.2 other than the TWRP recovery and the modified EX kernel for 4 cores.
Since the fix, my phone FINALLY got the OTA update to go to Android 8.0 and i obviously want to get it done. My concern is HOW to do this without causing more headache.
Can anyone point me in the right direction? Should i use the OTA update or download the factory image from Google?
I've got some knowledge as i used to be into the "rooting" scene back in the day, but haven't for a while, so i feel a little lost.
Thanks for any help.

Well, for starters do NOT take the OTA. It will either fail or boot loop your phone. Due to the fact you have a modified boot.img you will need to update manually using fastboot with the full image. Re-apply the modified kernel after you finish updating the partitions, but BEFORE booting the first time. You can follow most guides on how to manually update a full image using fastboot, just add the step of flashing the modified kernel before booting.
Thanks for the reply and the help. If i could ask for a little more help, as this is my only phone.
Can you explain the difference between the modified boot.img and the modified kernel?
If i download the factory image from here (https://developers.google.com/android/images) is it ok to the get the latested one (Nov 2017) or do i need to get the original one (Sep 2017 as i'm on Fi)
Once i flash the factory image, is it going to replace the modified boot image as well as the modified kernel?
Follow the OP on this thread (https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279) in the downloads section there appear to be 2 files i would need, the "Boot.img from stock 6.17, 8.0 firmware" and "EX kernel version 5.03". Am i understanding that correctly?
Like i said, this is my only phone, and i'm probably just being overly paranoid about bricking it, but any clarification would be greatly appreciated.

Use the latest November image. The boot.img contains the kernel and ramdisk, critical files necessary to load the device before the filesystem can be mounted. When you flash the new boot.img contained in the Google image, it will overwrite the patched kernel. You then need to re-patch it by installing EX kernel before booting. EX writes to (modifies) the stock boot.img. There are also pre-modifed boot.img files floating around. You will probably get more detailed help in the dedicated thread. Learning to flash manually (or remember how) is not really a big deal and a necessary skill for modding (and for getting yourself out of trouble). Good luck. :good:

Ok, so 1 last time (sorry)
1 - Downloaded the latest 8.0.0 factory image from google (this contains the bootloader, radio, and partitions (.zip).
2 - Get phone to fastboot and apply the above 3 new images
3- before rebooting, flash oreo4core (new, modified boot.img), TWRP recovery.img
4- reboot to recovery (TWRP) and apply the modified EX kernel
5 - reboot and (hopefully) profit
Am i missing anything, or doing anything that isn't needed?

<<Disclaimer: I don't use the 4 core kernel, so I don't know if it comes with installer script or someone has just modified the latest boot.img>> Unzip the "partitions" zip you refer to and extract those image files to the same folder as bootloader and modem. For example, you can keep TWRP recovery if you don't flash the recovery.img. That is how you preserve your custom recovery. So in other words you'll now have a folder (your ADB folder?) with 5 image files.... bootloader, radio, boot, system, and vendor all in one folder. <<Note: it is my understanding you just substitute the latest oreo4core file (should be boot.img?) If this is true, copy that file into your ADB folder and let it overwrite the stock boot.img. Stop. Copy over flash-all.bat, change the *.bat extension to *.txt and open in notepad. You will see (and can copy/paste) the fastboot commands to get you started with bootloader and radio. Then flash the last 3 (boot, system, vendor). At this point you can reboot into the OS. Since you substituted the oreo4core boot.img file for the stock boot.img there is no need to use TWRP to flash anything. That and since you skipped flashing the recovery.img, TWRP is still there.

Thank for the help! Everything seems to be up and running. I know you said you don't use the "4 cores" (can only assume your either on a different phone or yours isn't affected by the BLOD), but do you know if i still need to apply the EX kernel update, or know of a way to tell if it's already been applied?
Thanks again for all the help. I was pretty much in the right direction, but being as how i'd been away from it for a while, i wanted some backup

I know you said you don't use the "4 cores" (can only assume your either on a different phone or yours isn't affected by the BLOD), but do you know if i still need to apply the EX kernel update, or know of a way to tell if it's already been applied? Thanks again for all the help. I was pretty much in the right direction, but being as how i'd been away from it for a while, i wanted some backup

I don't think you can flash EX kernel from now on. I think you have to use a modded boot.img that will contain his kernel/ramdisk. This is my guess. You really should be getting your information in the dedicated thread where everyone is actually installing and using it. Google "oreo 4 core" and you will find the XDA thread is the first hit. Good luck. :good:
Hiya, after redoing lafsploit on my v20, the device only boots to recovery and only twrp 3.4.0-1 works. anything newer and it boots to fastboot.
as we all know, LG has crippled fastboot.
device also crashes/reboots any time you try and write to the device be it flashing roms or copying a file with twrp.
anyway, I'm looking for a solution.
Hey Eriklion,
I am not a pro, in fact I have only rooted my Samsung Galaxy S4 so far, and right now reading everything I can to root my H918, so read what I wrote with a healthy dose of skepticism, because I am most likely completely wrong, but, since no one else is responding I am compelled to try.
If you have followed the thread:

to KDZ downgrade to "h" and then use lafsploit to flash the TWRP, then in those instructions, there is a slight error:
the instructions do not clearly specify to use only a particular version of the TWRP, yet, that seem to be the requirement.
You can see that discussed in:
H918 Stuck on secure startup "decryption unsuccessful" on boot
after doing this https://forum.xda-developers.com/v20/how-to/step-step-guide-lg-v20-h918-unlocking-t3808258 and finally installing a stock based rom, which is Alpha Omega Rom. I get stuck at secure startup and telling that decryption...

Now, in your case, you do not have a decryption issues, but I think the actual results may vary, depending on what version of recovery you flashed using the lafsploit from FWUL.
As to how to fix..? Well in the latter mentioned thread they seem to all suggest fastboot flashing the correct version of TWRP, being very careful not to forget to use advanced format data from the boot to the TWRP that is immediately follows the TWRP flashing process. However, everything I read seem to be telling me that the flash over the fastboot is impossible for the H918 (and I think you mentioned this in your OP), so IDK what they are talking about.
May-be it is possible to reload the TWRP (this time a correct version) the same way you just installed the 3.4.0-1?
If not, may-be reflashing back the "h" KDZ, and then flashing the correct (3.2.3-4) version of TWRP from FWUL?
And do not forget that advanced format of data partition, which has to be completed no later than the first boot to TWRP immediately after TWRP is flashed on, i.e. before the device gets to complete even one boot to system!
This is all I can say. Please, let us know if your issue is resolved and if yes then how. Good luck!
Hi Eriklion, any progress for your situation?
