Hi All,
My Nexus 7 LTE is rooted with TWRP.
I've downloaded the OTA for 4.4.3 from one of the posts in the forums. It updates my razorg from KOT49H to KTU84L.
After using adb sideload, the update zip file is transferred successfully to my device, but it fails with the error message
Code:
"/system/bin/surfaceflinger" has unexpected contents.
error excuting updater binary in zip '/data/media/0/sideload.zip
Does anyone have any idea what could be causing the update to fail?
I've already restored to a stock kernel (from franco kernel) as well as uninstalled xposed framework.
Thanks!
Install stock recovery and take ota as normal. Then reinstall twrp and reroot.
If you fail update I have a backup I made with twrp you can use. Just need to extract it to your twrp backup folder and restore. It's 100% stock and was made after wiping data. Can't post a link to my Dropbox right now because of my post count but if you need it I an send it to you by other means.
Thanks for that. I think I might have to flash stock recovery and give it a shot, although I have a feeling even if I do that, it might not work as my tablet is no longer stock, since I've installed apps which made changes, such as FKU as well as CF-Lumen.

To get the OTA to work with either a stock or custom recovery the unexpected contents error will have to be fixed first. Somehow the surfaceflinger file was changed, that's a new one for me so I have no idea what could have changed it. I could upload a copy of mine if you want to try it but I do have the wifi version and don't know if they are the same. Otherwise you will need to fastboot flash the system image for the version you are running now for the update to work. Instead of doing that I would download the 4.4.3 factory image and extract the radio, system, and boot images and fastboot flash those. The bootloader did not change so that does not need to be flashed. Before flashing the images I would download the newest supersu zip and put it in your device storage, then flash the images, once that is done do not reboot, boot into recovery instead and flash the supersu zip then wipe cache and dalvik then reboot. Should take less than 15 minutes. ; )
You could also flash the factory image but that will install the stock recovery, lose root and completely wipe your device. If you are using windows you can open the flash-all.bat with a text editor like notepad and remove the -w from the text, that will prevent the userdata image from being flashed which wipes your device.
Thanks for your reply, wantabe.
I guessed as much, that if I couldn't figure out what changed the surfaceflinger, I might as well do a complete flash back to stock, which was what I did. Now it's just a matter of flashing back TWRP, restoring all the apps and waiting for 4.4.4 :good:
I've downloaded the ota zip and ready to flash it in twrp. But when I flash it, it shows an error saying my device have wrong build number. I'm very sure that i have kitkat ktu84p but when flashing the ota it says i have the previous jelly bean build which makes my flash unsuccessful. I've also checked build.prop and its also listed there its ktu84p. Whats the problem here and if possible show a solution please

Thanks for the link. Now i can conclude that the ota doesnt work with custom recoveries. Tried twrp and cwm. Twrp shows jelly bean fingerprints but cwm shows another kitkat fingerprint rather than ktu84p thats suppose to be

Wonder if you are using an outdated TWRP version. Maybe the newer versions have fixed this

I dont think so cause ive just updated it to 2.8.1.0 which is the newest by now
I tried everything and still get wrong build fingerprint when trying to flash the 5.0

Hello!
Really want to flash the OTA without a total wipe.
First flashed it from TWRP 2.8.1.0 and got the wrong build finger print says I have Flo:4.3/JSS15Q/779366 and it expects KTU84P/1227136
Then using WugFresh 1.9.4 flashed stock recovery so I could sideload then encountered the whole adb disappearing in recovery - eventually solved that and finally managed to adb sideload saw my screen saying it was installing the update using the stock recovery - YAY! It was short lived as the stock recovery screen told me the exact same thing that TWRP had told me.
I looked at my build.prop and it says my ro.build.fingerprint=google/razor/flo:4.4.4/KTU84P/1227136. user/release-keys
Can someone enlighten me? I've wasted so much time on this I would love some keen insight - PLEASE!!
Thanks for any and all help!

Google changed the way OTAs work in 5.0. You will usually not be able to flash a OTA if your OS is modified. Means no custom recovery or root. You will have to flash your tab back to stock kitkat.
Before it would patch individual file blocks, now it patches the whole system partition as a blob. Read more http://www.androidpolice.com/2014/1...e-means-update-will-fail-system-modified-way/
Workaround that helped me upgrade
Following the steps below seems to have done the trick for me. My issue was that Android 5.0 updates the system partition all in one go now, rather than each file separately. Following those steps will unroot your device but will allow you to install the OTA updates.
So follow these steps to refresh your current Android version (e.g 4.4.4) then use OTA or adb sideload to update to, for example, 5.0.
This will not wipe user data or the cache.
Download the Factory Image for your current version of android from google (4.4.4 most likely)
Extract each level of compressed files until you get to a .zip file (inside will be boot.img, recovery.img, and system.img)
Move these files to your ADB directory (optional step, makes the commands shorter)
make sure your device is connected with working drivers and is in bootloader mode ( adb reboot bootloader )
perform the following commands:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system
fastboot flash system system.img
Finally, (Re)start the system
After this if you want to root and reinstall a custom recovery , follow the normal steps.
I would post my source, but as I only just joined to say what helped me, I'm not allowed to post links I'll just say Google "flashing-a-stock-android-image-without-wiping-user-data" and (as of 19/11/2014) it's the top result.
Please continue here: http://forum.xda-developers.com/nexus-4/help/android-5-0-0-to-5-0-1-update-t2972371#post57515317
Finally finally!!! A fix!

Thank you Raingram! This worked perfectly!
Hi all, so I have Verizon's Pixel XL. I have unlocked it successfully and had rooted. I asked on the forums about upgrading the OTA update and was told it was fine. After doing so, I noticed my SuperSU was gone (although I might have lost it earlier and not noticed). So after trying to get it back and keeping getting stuck, I bit the bullet and ADB sideloaded the factory image from google (NDE63X) and got it able to boot up. Yay.
So then I ran the 'adb reboot bootloader' command, then verified my device was connected with 'fastboot devices' and finally I ran 'fastboot boot boot-to-root.img'. And here I am, stuck on the splash screen again.
So I looked around and saw some mentions of people that had used older versions of Chainfire's SuperSU. I tried the newer one (2.78 SR3) and the same thing happened. I do see that there is a SR5, but I also see Chainfire's comment "Do not use the SuperSU ZIP on work-in-progress TWRP releases for Pixel, it will not work - use the model specific links above instead.
I can get it to run just fine without using chainfire's supersu...but then I don't have the supersu app or any real gains from having rooted.
So, I feel like I must be doing something wrong. Any suggestions?
@smokeydriver,
You probably should update your Android SDK package. This problem can also be caused by an obsolete fastboot.

The OTA update I took only got me to a new version of 7.1, not 7.1.1 (from NDE63P to NDE63X). It still shows an available update to 7.1.1 which I have *not* done.
Try using the Unified Toolkit. It saved me from having a bootloop disaster when I tried upgrading from 7.1.1 due to poor instruction availability around the web. It should fix whatever problem you are having, even if that means flashing the factory image first again.

I've tried, but keep getting an error 21 code that it can't install...I tried this with SR5 and SR2.
How I Rooted
Personally, I'd flash to latest OTA via Unified Android Toolkit before starting this process.
Then use Minimal ADB to flashboot boot twrp.img (The Alpha2 Version)
AT this point you should already have 2 zips on your phone, TWRP-RC1 and SuperSU v5.
Flash TWRP, then SuperSU.
Reboot into OS, confirm root, give it 5 minutes.
Reboot back to Recovery and flash Kernel if desired.
Do not flash root with RC-1 (thats why we flashed root while using Alpha2 adb twrp.img), do not restore backups made with Alpha2 using RC1 or vic versa. AKA Backup and Restore with same version of TWRP.

Ok, I must be doing something wrong on a very basic level. It gave me error 21 (signature verification error) when trying to use the unified android tookit to install 7.1. Anyways, I'll just move on and skip that step and see what happens.
Flashing SuperSU SR5 works just fine with TWRP RC1. All you have to do is delete the file you're told to before flashing.

I transferred those 2 files to my download folder on my phone, ran the twrp.img script, and then when I go in...the file names are not normal. Everything is random letters and numbers. Again, I feel like I'm making some stupid basic mistake that I don't understand (and I've rooted plenty of phones).

Ah, I see. I misunderstood. I thought you were just under the impression that you couldn't flash SU with RC1. My apologies.
Ok, so can someone tell me why I am getting stuck with 1 thing. I go to my stock recovery and into ADB sideload. When I tell it the file, it keeps failing to verify whole-file signature. What is wrong with this one step?
Or alternatively...when I'm in TWRP Alpha 2- why are all the files within the sdcard random letters and numbers?

Twrp is not decrypting you're data. Try rebooting twrp from fastboot a second time.

Can I ask you how you fixed this? I'm having the same issue and this post popped up on Google.
I have a brand new Pixel XL from Verizon that I received today and was successful in unlocking. However, I tried to root and now I am stuck on bootloop. I cannot post in DEVELOPMENT because I haven't posted here in years (haven't had ANDROID in a while). Can anyone help? I am able to access via fastboot (I believe) but I must be flashing the wrong images. I don't want to brick this nice new day-old device. I have been at it for 5 hours via research on my own, but now I am looking for someone that can help me via P.M. or what it may take. I really want to get back to enjoying this device! Thanks in advance!

Read the third post in the thread below to get set up and back to stock. Then we will work on root. If you tried to root and you bootlooped it then you used the wrong SU.
https://forum.xda-developers.com/pixel/help/stupidly-bootloop-help-t3554242
1. Download a ROM. A stock version is probably in the forums somewhere if that's what you want.
2. Download TWRP image and zip from the TWRP thread.
3. Download SuperSU from the SuperSU thread.
4. Download a vendor image. There's no "official" vendor image thread AFAIK, but you can grab one from the Pure Nexus rom thread. NMF26V is compatible with all 7.1.1 ROMs & stock.
Now you have two options:
Fast: Put the ROM, TWRP(zip only), SuperSU and vendor image on USB flash drive, then connect the USB 3 to USB C adapter to your flash drive. Don't connect it to the phone yet. An external HDD/SSD should also work if that's all you've got.
Slow: While in TWRP(Instructions below) push the ROM, TWRP(zip only), SuperSU and vendor image files to your phone through ADB with "adb push C:\file_path\ /sdcard/" sans quotes. You will need to do this for each file, or alternatively push a folder containing the four files. adb file transfer is very slow.
5. Boot your phone to the bootloader, and connect it to your computer. This can be achieved by holding volume down and power from an off state.
Note: If your device is still bootlooping you won't be able to get to the bootloader. Hold volume up and power until the device shuts off to get out of the bootloop temporarily, then boot to bootloader.
6. In a command window, "fastboot boot twrp.img"
7. Connect your flash drive to your phone if you chose that option, or push the files through adb if you chose that option
8. Flash TWRP zip, ROM and vendor image. STAY IN TWRP
9. Return to TWRP's home screen > advanced > file manager. Scroll down until you see 'fstab.marlin'(in the root '/' directory). Tap on 'fstab.marlin' and delete it. Skipping this step means SuperSU won't install.
10. Flash SuperSU zip, reboot to system and you're done.

Thanks for your assistance. I now have root installed and I think I'm good except for one thing. I keep thinking TWRP is installed but for some reason when I reboot to bootloader, then select reboot recovery mode, it takes me to android recovery. I am used to recovery taking me to TWRP. I know TWRP works but I feel like I'm temporarily flashing it each time or something. I even installed the twrp app and I see I can flash zips that way, etc, but I wanted to know if you knew how to make the phone boot to TWRP in recovery? Or is that necessary?

I dont do it that way on this phone. TWRP and SU are modifying the same parts of the phone, and there are cases where it could conflict. Rare, not a big deal, but since i don't need TWRP installed i don't.
To install it ypu first boot to it.
Fastboot boot twrpFilename.
Then from within TWRP you install the TWRP zip.
Make sure it is TWRP RC1
All set
Thanks again for your help. I am running pure ROM as I mentioned and I seem to like it. Do you K or if Franco works with Pure or do you have a suggestion on a good rom/kernel? Is there anything else that you can suggest I should be using with the new phone? I remember there used to be tools that you could install that allowed you to customize the system even further but the name escapes me. . Is there anything like that or even a theme tool which is a must have when you are rooted and running custom roms? No big deal if not. Very happy with where I stand now. Really appreciate you getting me back up and running!
You are most welcome. I don't ROM so I don't know what kernels work with what roms for sure. But my understanding is that they are all pretty universal. I run stock with Franco.
Other than that i dont mod much. Ad blocker, black themes and a few adjustments to Franco.

Im running pure and elementalx with excellent results.
?Tapped from my pure pixelXl?
have you ever seen an issue where the phone boots to twrp even though everything was working fine? It starts happening if I do a restart. Then no matter what it boots into TWRP unless I wipe again? I believe it's happening after I flash root but I'm going out of my mind with trial and error. Any help would be appreciated.

HELLO!!! I understand any frustrations you may be having, as the pixel devices have changed a good bit for us as far as development. Anyways. I'm just going to throw some knowledge out there, then proceed to help get you up and running!
You couldn't post in the development section because of your post count, but even if you could, it would have been in the wrong section and it would have been removed, or moved to the questions section.
Also, I see someone has pointed it out earlier, but I'll say it again just to make sure everything is clear. The command you were running "fastboot boot TWRP.img" only boots TWRP temporarily. You are suppose to have two files, one IMG file and one zip file. You boot the IMG file, then once you're in TWRP, you flash the zip file, then reboot to recovery and you will have installed TWRP properly.
With root, flashing wrong files or using the outdated root method will cause boot loops. The correct way to root (again already been said) is the get TWRP up and running, delete the fstab file (see earlier post) then flash SuperSU and reboot. Just throwing this out there Incase someone comes across it, if you manage to boot loop your device due to to rooting, you can fastboot flash franco's kernel and it will fix the bootloop (,but you won't have root) this isn't the correct way to fix it, but it will get you back up and running without downloading the large factory image.
***About to edit this post to continue giving more info***
Here is a correct guide and good template to get you running.
start by flashing a clean factory image, then let it boot and get it set up.
Reboot to fastboot, fastboot boot TWRP IMG then flash TWRP zip using the latest versions (RC1 is latest, pm me for more info).
Reboot the phone to recovery to ensure TWRP stuck.
Go-to advanced, file manager in TWRP and find the fstab.marlin file and delete.
Then you can go ahead and flash the latest SuperSU (I use 2.79 sr3) and when it's done reboot to system and verify root.
After rooting you can go ahead and flash a kernel if you want, I use elemental which you can flash in TWRP, but see the kernel instructions prior to flashing.
Reboot and you have a nice stock ROM with root and kernel.
For flashing Roms, kind of follow the same template, most Roms require you to flash part of or the whole latest factory image.
If your on a clean install, go ahead and install TWRP as mentioned above.
Then use TWRP to install whatever ROM you want per ROM developer instructions.
Side note, some Roms replace the TWRP with cwm or stock recovery, so it's always nice to flash the TWRP zip after flashing a ROM.
After flashing ROM, boot to system to make sure all is well, then boot back to recovery and follow instructions above for root/kernel.
As far as the problem you're having now, it usually comes from flashing outdated SuperSU images. Do a search for 2.79 sr3 and use it to root (pm me if you need help)
You might have to start clean one more time, And flash factory image.

Just throwing this out there Incase someone comes across it, if you manage to boot loop your device due to to rooting, you can fastboot flash franco's kernel and it will fix the bootloop (,but you won't have root) this isn't the correct way to fix it, but it will get you back up and running without downloading the large factory image.
***About to edit this post to continue giving more info***
Here is a correct guide and good template to get you running.
start by flashing a clean factory image, then let it boot and get it set up.
Reboot to fastboot, fastboot boot TWRP IMG then flash TWRP zip using the latest versions (RC1 is latest, pm me for more info).
Reboot the phone to recovery to ensure TWRP stuck.
Go-to advanced, file manager in TWRP and find the fstab.marlin file and delete.
Then you can go ahead and flash the latest SuperSU (I use 2.79 sr3) and when it's done reboot to system and verify root.
After rooting you can go ahead and flash a kernel if you want, I use elemental which you can flash in TWRP, but see the kernel instructions prior to flashing.
Reboot and you have a nice stock ROM with root and kernel.
For flashing Roms, kind of follow the same template, most Roms require you to flash part of or the whole latest factory image.
If your on a clean install, go ahead and install TWRP as mentioned above.
Then use TWRP to install whatever ROM you want per ROM developer instructions.
Side note, some Roms replace the TWRP with cwm or stock recovery, so it's always nice to flash the TWRP zip after flashing a ROM.
After flashing ROM, boot to system to make sure all is well, then boot back to recovery and follow instructions above for root/kernel.
As far as the problem you're having now, it usually comes from flashing outdated SuperSU images. Do a search for 2.79 sr3 and use it to root (pm me if you need help)
You might have to start clean one more time, And flash factory image.

There is absolutely no need to delete the fstab file anymore. That only needed to be done when TWRP was still alpha 2, and almost three versions of su earlier.
ALL roms replace TWRP with stock recovery unless you are using lineage then you will get Cyanogenmod recovery, so reflashing TWRP before booting into system is a must.
If you are flashing root and or custome kernel and end up in a bootloop, flashing the stock boot.img to both slots via:
'fastboot flash --slot _a boot boot.img'
'fastboot flash --slot _b boot boot.Img'
will fix the issue and you will be able to boot up just fine. Again you will have to reboot into TWRP from the bootloader and reflash the zip. When you are done flashing the boot.img's you might as well just
'Fastboot boot TWRP-file.img'
Then install the zip!
Hi,
Googled a while and looked around in the forum but did not find anyone with the exact same issue as me so here goes.
Maybe someone could tell me where exactly I am doing wrong.
I have a LG Nexus 5X, latest Oreo 8.1 official update.
I want to install a custom kernel to improve performance and/or battery life.
Never rooted or anything like that so I googled around to know what to do.
So I unlocked the bootloader and flashed the latest TWRP custom recovery (v3.2.1-0).
The first strange thing unlike what I kept reading in tutorials and forums is that, although I did reboot directly into recovery after flashing TWRP, and completed flashing TWRP using its interface, I was never able to reboot into TWRP unless I flashed it again. As if TWRP could not avoid being overridden by the stock recovery. So to get back to TWRP I always have to:
reboot into the bootloader: adb reboot bootloader
flash TWRP: flash recovery twrp-3.2.1-0-bullhead.img
reboot bootloader: fastboot reboot
immediately start into to bootloader (power + vol down)
choose 'Recovery Mode' from there
Which seemed odd, that TWRP wouldn't 'stick', although I was not root yet.
Which gets me to the second part. All I wanted was to root my phone.
So after not finding a consistent way to do it - it seemed every website I visited gave me slightly different instructions to do so, I took the chance and did the following:
download latest SuperSU flashable zip file (v2.82) and copy it to internal storage
go through the process I describe in the list above to get into TWRP
install SuperSU zip file (via Install TWRP option, logs seemed ok, warned me it would take a while to boot again)
reboot, wait until it boots
But the phone got stuck in the boot screen - OS does not start to load - for at least half an hour.
Luckily, probably because the OS did not load, TWRP was not overridden and so I have access to it.
My main problem at this point is that, as a newbie on this, I am not sure what can I do in TWRP to try to restore the OS.
I have tried to restore a Nandroid backup I performed before all this, and also tried to Wipe Data / Cache and Dalvik.
Both did not work - OS still won't load.
What can I do at this point? Wipe System partition? Wouldn't that delete my Nandroid backup?
Maybe 'sideload' (not sure if the right term) an official google image for my Nexus?
Sorry again if questions like this can be easily found around the forum, but from the threads I checked I did not bump into the exact same scenario...
Thank you in advance
So in the meantime I have wiped system partition, no success either.
Ended up restoring my Nandroid backup and sideloading the latest OTA from Google, which successfully restored my phone.
Of course TWRP was overridden once again.
So back to the start: can anybody help me out on the best way to permanently flash TWRP and root the phone?
Thanks!
Forget SuperSU - Use Magisk to root your phone. As for TWRP getting overwritten - any time you take an update from Google, it will generally (if not always) restore the stock recovery. The way to get around that is to download the entire current update from Google and then use fastboot to flash the individual parts (system.img / boot.img / radio.img / vendor.img)

Well yes, the last time I expected TWRP to be gone since I have applied the whole image, and I wouldn't expect otherwise. My problem is that TWRP is always getting overridden each time I reboot my phone. Do you have any idea why?
Regarding Magisk, I will look around to see how to use it. Could you point me in the right direction?
Also I think I read somewhere that the kernel I wanted to flash in the end - Franco's Kernel - required SuperSU and did not work with Magisk. Am I wrong?

Here's the guide stickied that should walk you through the TWRP install. https://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930
Just curious you are using "fastboot flash recovery ....." and not "fastboot boot recovery...."? The "boot" method doesn't do the install.
As for Magisk. There is a whole forum dedicated to it - https://forum.xda-developers.com/apps/magisk - Short story install the latest stable version (16.0) and call it good. I haven't had any issues with recent kernel builds including Franco, EX, etc.... One thing to keep in mind is that Magisk always gets flashed after the kernel install as it does some patching of the boot.img as part of its process.

Yes, flash, not boot.
Thanks a bunch for all your help. I didn't meant to be lazy to start by reading sticked topics, but it's so much new information for a newbie that I didn't exactly know where to start. Thanks again for sharing the links.
I'm not sure if you got this fixed. But if not, first fastboot boot twrp. Then flash supersu or magisk. Then boot back into the bootloader from twrp and fastboot flash twrp. That'll solve the problem.

I tried that but I'm getting no luck with SuperSU, always gets me in a bootloop (actually, technically not a loop since it remains Frozen with the Google logo)
I'll give magisk a try and come back with feedback. Maybe it has something to do SuperSU incompatibility with Oreo 8.1..

What version of super su are you using? Use 2.82 SR 3 or 5

V2.82 Stable, not Service Release. Is the last stable not compatible with Oreo? Official website is not specific about it, so I just assumed it was ok.

3 or 5 work on Oreo. I'm not sure about stable. I don't use it.

SR5 worked like a charm. I just wish there was a compatibility matrix somewhere in their website to avoid so many forum threads and misinformation on the subject and avoid all the hustle. The whole process is dead simple but it took me days and tailored help from you guys to figure this one out.
Thanks again to all of you for your assistance.
i had that issue with a nex 6 and flashing supersu fixed it. when i got a 6p i tried the same and get stuck on the boot logo and had to sideload factory firmware to get back to go. i have a 5x on the way maybe i will try magisk.
so after i flash twrp reboot the bootloader, i open twrp and flash supersu sr5 and all is well, no more disappearing act for twrp and no more stuck on the "google"?
