Ive been fidiling with andorid devices and root for a long time now,l but I never went into dual boots, I was wondering if I can dual boot on my nexus 6p, say like stock rom and purenexus?
Use a twrp nandroid and just flash between the 2?
I've never seen an actual dualboot with a menu or whatever.
Eventually multiRom will be ported over, until then, sit tight.

If I do decide to unlock my boot loader, could we dual boot roms?

Not as of now though it *may* come though I doubt it seeing how not many other tablets have dual boot features either. One way to simulate it is to just set up a ROM then back it up in recovery and then wipe and set up a new ROM and then backing that one as well. Then restore the one you feel like using. Sure it takes ages for backups to restore but it works for now.
Hello XDA,
First time posting so I have to ask in Q&A rather than the thread for MultiROM itself. I've been to these forums quite a few times for rooting and unlocking other's devices, but now that I have a Nexus 7 myself, it's time to start messing around with it.
So the situation for my problem is that I have successfully installed MultiROM and was able to boot up my stock image fine, but when I installed Cyanogenmod 10.0.0, the screen automatically goes to the boot screen for Cyanogenmod rather than asking which ROM to boot and then just hangs on that boot screen forever.
I have not used the kexec hardboot patches for anything yet so it can be that I should be using those somewhere along in the process.
Also, how do I go about uninstalling MultiROM so that I can start all over again? Do I just go into TWRP and hit "install" and choose the stock image for 4.2.1?

It's overwriting the kernel with one of its own... that's the only thing I can think of. Flash a kernel that has MultiROM support like m or motley.

Does this mean that I should find a version of CM that has one of those kernels? Or do i simply flash the kernel by itself and that would overwrite the CM kernel so that the problem would be resolved?
Also I tried installing Kaos Droid and chose the option to install the M kernel before CM actually and I remember that it also would just boot to a completely black screen and nothing past that. So i'm not sure if it's the kernel. But i did just successfully go back to stock and rooted again so that I will try out your suggestions tomorrow. Thanks.

You can flash the kernel separately and it'll be fine.

Hey. Long time reader, first time poster. I've had Android devices for forever, never had a problem with flashing/installing ROMs, or anything else. That changed today.
My Nexus 7 (2012) had CyanogenMod 10.1 installed, and I decided I wanted to go back to stock. I used ClockWork's ROM Manager, found the highest rated N7 stock ROM, downloaded it, and started the install. I have TWRP installed. Installation was going fine, no errors or anything. I had it plugged up to the charger, left it alone, and went downstairs to eat breakfast. Twenty minutes later I come back, and it's still on the X boot animation. So I left it, came back thirty minutes later, still there. Assuming there was a problem, I tried to reboot into recovery to see what the deal is. I cannot seem to get into recovery mode no matter how hard I try. What can I do now?
TL;DR - N7 flash from CM 10.1 to stock; stuck on boot animation; can't get into recovery
Thanks!

Download the Android SDK and the latest Nexus 7 factory image, and then flash the image via fastboot.
Or, you can find a "back-to-stock toolkit" that will flash the factory image for you.
If you need further help with those tools, Google is your friend There's tons of documentation out there on how to flash Nexus devices back to stock.
Hi all,
I've purchased a Nexus 4 which had a broken screen to play with as a testing environment, I've replaced the entire digitizer and confirmed the screens working through TWRP.
From what I can see when I got the phone to boot to recovery, the previous owner has attempted to flash a Nexus 5 stock image onto a Nexus 4.
I've wiped all available partitions and tried;
1) Stock factory Google Android Images
2) Latest version of CM10 for the Nexus 4
So far in stock Android I cannot get the phone to boot past the Google Android 'X' splash screen, the phone boots after imaging CM onto the phone, but the screen is not responsive. I know for certain that the hardware isn't at fault as the screens responsive in recovery.
Any ideas on what I can do to get this phone back to stock? I suspect there's something wrong with the partitions on the phone from the previous owners failed flash attempts.

If they tried flashing ROMs for another phone try this:

That might do it

Thanks man, I'd have had a hard time finding that thread. I'll give it a craic later this long weekend.
Again, thank you very much.
For everyone interesting into upgrading to Android 7 be warned that are some issues going around right now and no one really knows what is causing the problems or what the fix is. So I was running the latest Pure Nexus rom and upgraded to Android 7 using the OTA file and the boot.img provided. Everything went fine and the system boot correctly. Well I decided to flash Pure Nexus back and the system was stuck in a boot loop between the white google logo and the "The system can't be checked for corruption" screen (unlocked boot loader). Well the good man Heisenberg got involved and recommend his full system stock restore guide (without locking the boot loader; don't do it or you will be completely out of luck). I used his guide and flashed 6.0.0 (MDA89D) and also 6.0.1 (MTC20F). The phone continued to boot loop and never boot. I was still able to boot into TWRP, so I tried a manual flash of Pure Nexus and MTC20F Vendor, no luck... Then I tried reflashing the Android 7 OTA update and boot.img, still a boot loop... There was an earlier thread about this issue, but I felt led to make sure this news and warning gets out!!! I ended up contacting google and project fi and I am getting a replacement phone.
While this issue seems to be rare I want to list my conditions in hoping preventing the issue for you!
- I was on MTC20F Vendor (with Pure Nexus)
- I flashed the Android 7 OTA update from the latest Pure Nexus build
- I did a semi dirty flash (could be root of problems) (I did this due to a recommendation, that was meant for a stock android 6 to 7 upgrade)
- The root of the issue could be going from a custom rom to the stock Android 7
- My system was rebooting and restating just fine with Android 7
- I wiped my system and flashed Pure Nexus back and the issues started
- This issue for now has no fix; Heisenberg (really thanks man) was a big help but didn't know what to do about it
Hey anyone who sees and reads this; would super appreciate answering the poll so we as a community can collect data about this problem to help prevent it in the future. Currently there is no fix for this weird semi(can access recovery)/hard(never boots into system) brick
Thank you!
Sounds like you should have just flashed stock before flashing the N OTA.

same thing happened to me, i cant return to stock or 7 or backup, nothing
An important warning to all upgrading to Android 7 right now!
I currently find myself stuck on the boot animation (the colored circles) after trying to flash 7 then going back to Pure Nexus. I did a full data and system wipe before trying to install 7, but it still hung on the boot animation. Now after restoring my nandroid and reflashing Pure Nexus I'm still stuck on the boot animation.
Edit: Whew, reflashing Pure Nexus then restoring just the vendor image seem to have gotten me back to M.

I am stuck like this as well. I can't figure out how to fix this.

My computer is not even detecting my phone with ADB... You know anything I might not?
UPDATE: Just had to unplug and replug my phone when in Recovery/Apply UPdate from ADB
stuck in bootloop as well....having google rma my device...flashed the aosp build of nougat just to test it out, then restored my backup of official noougat and got the bootloop...no clue what else to do in this case
I updated to 7 and then downgraded to 6.01. Boot loop city. I've spent 10 hours trying everything I could to fix it.
