I've got a bit of a problem with my Nexus 10, I want to do a factory reset to remove encryption, but the factory reset fails every time. I've tried the stock one via the menus, and the clockwork one via recovery, but neither works. I thought I'd have a go at re-rooting it to see if I could force the issue, but the recovery isn't able to mount the SD, so I can't get to the file to flash. The unit is spoofing a Galaxy Nexus for SkyGo purposes, which seems to be causing the adb drivers to not work on my PC, as it's obviously not seeing it as a Nexus 10 when I connect. I can't remove the spoofing, as it needs to be rooted, which brings me full circle.
It's a right pickle!
Any ideas what I might be able to do to get the unit rooted again?

Custom recoveries don't deal with encryption, if I'm remembering things correctly. If your stock recovery's not working either, then that's a serious cause for concern (and is likely why factory reset isn't working for you). To be honest, you may be kind of hosed on this install around. I'd recommend that you boot up, back up your data using Titanium Backup, offload it (connect it to a PC/cloud service while device is on), then plonk into fastboot and just reinstall (or RUU).

Therein lies the problem though, for whatever reason my PC won't recognise the nexus 10, despite the drivers being installed from the ADK etc.
Because of that, I can't use fastboot or anything PC based. I suspect it's because the device is spoofed as a Galaxy Nexus.
The device is currently unrooted too, so that also limits my options.
My data isn't really a problem, I'm happy to wipe everything, it's all backed up on my NAS anyway.
Isn't there any sort of physical reset button anywhere that will force a factory reset?
Managed to get the drivers working on my gf's laptop, not sure why my PC wasn't playing ball, but this is all fixed now.
Ta!
So, I am new to the community and just recently created an account to make a new topic because something happened:
I have a N6P and I was disappointed with the whole "Pixel exclusives" thing, so I decided to root and flash some of the new features into the phone. Everything I wanted I could find in the threads of this forum and it was nice and easy. I did get to a nice point where I had all the features I wanted, and then, I saw that there was a beta update for the new android version 7.1.1. From there I realized how little I know about the android system, and for that reason I want to ask a few questions. First, I'll describe the steps I took and the result i got:
1 - Backed Up data with TWRP (Boot, System, System Image, Vendor, Recovery)
2 - Updated to 7.1.1 through the phone settings
3 - Reboot
4 - Checked everything (all working fine until here), I had lost my root and TWRP because the new system took place.
5 - Reflashed TWRP
6 - Patched again the Pixel Launcher and SuperSu through TWRP
7 - Reboot
From that time on, the phone did boot, but the default launcher didn't start and a system app presented errors: Everythime I closed the error box, if popped again, blocking me from doing anything.
After the inicial problem, I promptly went to TWRP and tried to restore the backup I made. Now the phone became unable to start the OS, it runs the boot animation forever and nothing happens.
Now I am downloading a Stock ROM to flash through fastboot and do everything again.
Now to the questions:
1 - What did I do wrong? Why didn't the Backup work? What should I do differently from now on to have a reliable restore point of my device(just in case I screw up again)
2 - What can I do (besides flashing stock room) in order to recover my system? It is annoying to have to start from zero again thinking i had a backup made just to prevent that.
3 - Where can I learn more about the Android filesystem and OS architecture? (I am a developer, but I'm also lazy as ****, so i'd appreciate "explain like i'm 5" links)
Thank you all.
Howdy, so I have been a member of the forums for quite awhile, and I just got this Moto G5 from swappa in the mail today and I am having a wee bit of probs with it. I was able to set it up no prob on the stock firmware and took the most recent software update that addressed the KRACK issue, however I noticed under security that Encryption is turned on and I have no option to turn it off. I may need to replace stock recovery first and try to send a command to it like adb shell recovery --wipe_data --set_filesystem_encryption=off which did not work thru twrp at all sadly, also I have tried to fastboot erase userdata which does in fact erase the data but once I go back into the rom and I skipped the fingerprint and locks etc the encryption stays on, does anyone know of some way to turn it off as I want to use multirom and keep the stock as primary in case I have probs and since twrp cant access the data folder like this i dunno if I should even try to run multirom at all, should i maybe root first I did not flash magisk yet? Any help would be awesome and appreciated as always I am sure someone on this forum knows exactly what to do thanks for your time.
Well update here I ultimately did more digging to find on an old post in which the download links were dead a spanish speaking dude tried to explain it in english best as he could, eventually found the links to a zip you flash after twrp to allow for workaround on the dm-verity checks etc flashed that then rebooted to system turned off without setting up then went back to twrp and swiped for system mods then flashed my rom and when it prompts to have you install the twrp app in system just choose no or at least not in system then it should go head and boot into your rom.
Yes this post is correctly dated. I've had this device a LOOOONNNGGG time.
The device has been rooted since shortly after I bought it new years ago. I've had very few problems since... which is why it's never been replaced.
I believe I have the stock ROM, sorry it's been a while.
When I start the device it gets stuck at the splash screen with the sprint logo.
I can get the device to "download mode" but I don't know what to do once there and I'm not sure I can do anything from here.
I can get the device to "android system recovery."
I know I installed TWRP when I rooted and installed the rooted ROM but when I boot to recovery it doesn't go there.
I've wiped the "cache partition" but the problem remained. I'm not sure what else to do from here and still be able to salvage data.
I'm trying to salvage the data on the internal storage. I'm pretty sure I could successfully "wipe data/ factory reset" and get it to "function" again but that's not the priority. I'm going to replace it regardless of success or failure. Data recovery is the priority here. (pictures and videos of my young children as well as less important stuff like contacts.)
I have an old laptop with an old version of ubuntu I can use or a newer one with windows 7 to work with. I mention this in case it makes this easier to help?
Thank you very much if you try to take a stab at this or refer someone that might!
Update:
So I managed to install TWRP via Odin.
I booted to this recovery and my data partition appears to be empty?
When I try to back up I get the error message "unable to mount '/data'"
I tried doing a wipe, not one of the fancy extra options ones just the regular wipe and it failed.
Any guidance will be extremely appreciated.
Edit:
So I've come to the conclusion that the data isn't accessible because of encryption and my pass code. Is there any way to enter it via recovery and access this info?
Is anybody out there?
Edit 2:
I hope this helps someone someday. I haven't solved the problem but I think I'm making progress.
First I had an old version of TWRP. I installed the latest for my device and tried backing up again. I'm not sure but I think it's working. TWRP dosen't seem to need my password for the backup. I imagine I'll just need it to access the data later.
Edit 3:
No sooner did I save the last edit and my backup failed.
Process ended with error : 255
Hi,
I have a Oneplus 6T A6013. Yesterday my phone had this state:
bootloader u
nlocked
root installed with magisk
a couple of magisk module installed
latest stable
stock rom (10.3.0)
Then an OTA update (10.3.1) arrived to me and I installed as usual:
OTA full download and
installation, without reboot
Magisk installation o
n other partition and reboot
Here begin problems. My phone reboot and get stucked on OnePlus animation.
I can force shut down, enter stock recovery, enter bootloader.
I can not rely on
Code:
fastboot boot twrp.img
because phone reboots and stucks on fastboot logo.
I decide to do factory reset phone, with Google backup it is not a big problem, during configuration I obviously login in with the same account and obviously backup is on cloud, but phone says "no backup found".
Moreover it seems that magisk root files were still present on the phone, and even "uninstalling" them from magisk manager doesn't remove sucessfully them.
At this point I have tried to make a completely fresh install of the OS:
during configuration still no backup found, even if I have created more backup in the meanwhile, one of them jsut before fresh install and on Drive I can see all of them
Google Pay sais that my system is not right, maybe cause root
using Magisk Manager I have checked that this time root is no more installed, but I can see that "cts check" fails
Play Store -> settings also says to me that "my phone is not certified"
Maybe I am not able to recover backup cause cts check fails. I have still bootloader unlocked.
So here are my questions.
Someone knows beacuse my phone doesn't recognize its own backups?
How can I pass cts check?
In case I should relock bootloader, how can I check that everything is truly stock and avoid a possible brick?
Thank you so much for your future answers, I have searched on internet and made tries for a whole day and contacted OnePlus chat assistence twice, but without any luck.
You have to actually wait a few minutes after running "fastboot boot boot.img" command to boot the TWRP, and you MUST use the latest one (always use up-to-date tools) which in that case is TWRP 3.3.1-31 - you have to use "Q" version of bootable TWRP image for OxygenOS 10.3.1 which is obviously Android 10 Queen Cake so be sure to use the right one.
Tethered Fastboot TWRP boot works just fine for me, in fact I installed crDroid 6.2 ROM atop OxygenOS 10.3.1 on my converted T-Mobile OnePlus 6T.
As for the bootloader, once it's unlocked, I strongly recommend leaving it alone unlocked unless you really like to use MSMTools more often. Use SafetyPatch in Magisk's module manager, it will fix the CTS SafetyNet issues. Locked bootloader actually causes more problems compared to unlocked one in my experience.

First of all thank you very much for your answer.
Is this type of twrp right?
I thank you really much for your suggestion about locking bootloader. I don't want to specifically remove root, the real problem Is that I am no more able to recover my old backup. I have just supposed that bootloader and root could be tha causes.
Before I fully reflashed OS I was able to Hide robot and pass all checks using Magisk, buy as I said I was not able to recover backup, neither a fresh and new just made backup.
I worry about the future. Now I could set again all the phone, but what will happens if tomorrow I will have to reset again?

I used latest version by fajita downloaded from my previous link. I have waited for 10 minutes stacked on oneplus fastboot mode logo and nothing happens. Now I have the problem that I am no more able to flash magisk...
That doesn't sound good - MSMTools may be necessary. Did you back up all the files?
If your T-Mobile OnePlus 6T is converted, install OxygenOS 9.0.11 and unlock the bootloader once again (MSMTools usually relock the bootloader, so unlock it again), then update to OxygenOS 10.3.0 or 10.3.1 via update zip file (I don't trust OTA updates at all, they tend to cause problems), then install the TWRP once you're at it, and then reboot back into the recovery and install Magisk if you want to.
Unless... You want to install custom Android 10 operating system which then you must do that; First reinstall OxygenOS 10.3.x ROM (in all slots, it is mandatory because you will install the same custom OS on both slots so it boots properly) then boot into TWRP, and do factory reset and data wipe in the Wipe menu, then reboot back into recovery and then plug in the USB flash drive or copy the TWRP, OS installation zip and whatever else you want installed onto the phone via the computer. Then install crDroid, LineageOS or any of OS of your choosing, and TWRP, and reboot back into recovery once again and install the OS and TWRP one final time in another slot. After doing the last reboot, install Gapps and Magisk. Finally, after you are done and reboot the phone after the installation, it will reboot by itself once - that's due to Magisk doing some configuration.
Android 10 apparently have made installation of custom ROM difficult. I have managed to brick my OnePlus 6T eight - ten times before deciding to find out how to do it successfully, thus the instruction for installation of custom OS above.
As for failure to restore the backup, this is the artifact of the Android 10 UEFI bootloader encryption (which is occasionally buggy, and annoying - just installing the LineageOS 17 the normal way, the whole SSD just gets corrupted, so the trick to get it to work is to, yes, remove all SSD encryption keys via factory reset prior to installing any custom ROM). As of now, TWRP backup is broken on most phones running Android 10 which is due to how the encryption works in this OS version (to the point they are so touchy).

Yes, my device is actually ready to be wiped and I have already the international version.
The problem is that MSMTools' link are down.

Do you mean "manual backup" such as nanodroid, or "automatic Google backup"?
I have no manual backup, only that one saved on Drive, it should be restored automatically during configuration of operating system.
Any way you can back it up. TWRP backup (and any nandroid) in general are broken for many Android 10 phones because of the SSD encryption - I suspect that by each reboots, new cipher keys may be generated every time, thus making it hard to be able to successfully reinstall the Nandroid backup at any point in time - they're like the snowflakes, each and every EXT4 ciphers are different. (All that is meant to resist the hacker attack, even on the custom ROMs - Google wanted to be sure they cover everyone in term of computing security, so all that encryption Voodoos are also in the AOSP and LineageOS repositories for that reasons.)
As for MSMTools, I really wonder. OnePlus didn't object before.

About MSMTools I have still some problem, fault of my really bad English...
I have not understood your answer, what does it means "OnePlus didn't object before"? Actually I am simply no able to download the tool.
Thank you again for your kindness
Striatum_bdr, that will do. The unbricking tool collection looks good.

Wonderful, I will read the "unbricking tool" thread in order to understand how to install it
Hopefully you get it to work once again.

Here I am with some good update
I have used MSMTools to truly factory reset my phone. Initially I had "sahara connection" error, but install again both Qualcomm and Oneplus drivers do the trick. After execution of MSMTools phone reboot with bootloader locked and as it was out of box.
At that point on Drive I had 3 backup (9 Feb, 10 Feb and 10 Feb) and magically last backup of 10 Feb was seen! Saddly even deleting last two backups I am not able to recover my true backup of 9 Feb (at this point it doesn't matter).
Now I have a virgin and working phone. I have no root and can use Google Pay and banking apps.
Really happy and satisfied, thank you thank you thank you very much!!!!

What is up with that? I booted into TWRP the other day, figured I would make a backup before upgrading, and everything was garbled.
That's because of the onboard encryption; all Nandroid backup being attempted on Android 10 only hold half of the overall encryption keys, others just stays on the phone, so when you attempt to put it back on, it is already invalidated because also Android 10 ROM on some phones (particularly the Pixels, and a few OnePlus phones like this one) changes keys upon reboots for security reasons.
Google do not want anyone including the US Government to have their hands on the data thereon as it could be very bad if it falls in the wrong hands so they went extra miles to make it difficult to hack.
