Robin on Nougat Won't Boot After Flashing TWRP

I just upgraded my rooted and bootloader unlocked Robin to Nougat last night by installing the official upgrade files from the Razer Community forum. I've tried installing TWRP several times through fastboot, and each time I can get the phone into recovery, but the phone will never boot into the system. It hangs on the black "Nextbit by Robin" screen, and never goes past it. If I turn off the phone by holding down the power and volume down buttons, and then turn it back on, it still won't get past that screen. I can always get into TWRP, though, but no matter what I do, the phone won't boot. I've been using TWRP 3.1.0. Is there a different version that's required for Nougat?

My guess is you messed up the boot.img, or worse you corrupted some partition. If it's the boot.img, go get the latest factory image, unzip it, and move the file 'boot.Img' onto where your adb and fastboot files are located. Then go into fastboot on your Robin, and run this command on your PC:
Fastboot flash boot boot.img
If you corrupted something, you basically need to go into fastboot and use the flash-all.bat in the already unzipped Robin_nougat_88 folder to bring your phone back bone stock.
Hope that helped
Had this issue with my phone at first, but eventually just fixed it anyway by flashing the decrypted boot.img.

I ended up fixing it the same way you did. No matter how many times I took it back to stock by flashing the files in the Robin_nougat_88 folder and then flashing TWRP, no matter which version of TWRP I used, it would never boot. I finally flashed TWRP, then booted back into recovery, wiped the phone, loaded and flashed the decrypted boot image and SuperSU, and then the phone booted fine. I should have just done that in the first place since it was always my intention to unencrpyt it and rooted it again, anyway.

Updated Android O stuck on G boot screen

Hey all,
So I updated my pixel xl to Android O, and then used the modified TWRP to flash Super Su, SUhide. The phone booted up and everything was perfect. It was a little sluggish so I decided to do a full factory reset... again, phone reset, booted perfectly. I then restored all my apps from the google play store cloud... phone was functioning fine.
I went to reboot the phone after a while... and now the phone is stuck on the G logo after the bouncing dots... and just continues to load.
It's been like that for over 20 minutes.
Is this normal? Anyway I can fix this?
Thanks!

I have the same exact issue after following the exact process described above. After a weekend of frustration, I was thrilled to see this post, but then bummed there are no suggestions. There is no way I can get it back to recovery, no matter what power/volume combination I try. The phone is not detectable by ADB either, so unless a kind soul has a suggestion, there seems to be nothing to do except let the battery die and hope.

Umm boot into bootloader and flash stock boot.img and system.img?

I would love to do that, but how is it possible if there is no power or volume button combination that can get me off of the Google boot screen and into bootloader?

Have you tried Power + volume down ? It'll turn off after release power button only. That or let the battery die and when you try to plug it up next time leave vol down pressed.

I have tried that, thank you. I will let battery die and do the Volume Down method you suggest, and report back.

That did the trick. Back to stock 8.0.0, and hoping to find a stable root method that doesn't hang-up on the first reboot. Thanks for the help!

First of all. Hold the power button for about 20 secs and the phone will reboot.
Hold vol - and you are straight to bootloader.
Second flash full factory to both slots.
And third stop using the - w solution when you are coming from another rom or a different stock version. We had this problems on other forums and it was every time - w or not flashing both slots. I know for many people there will be no problem but some apps are just misbehaving when you do so. And they are causing reboots and bootloops.

OK, thank you! I am not familiar with the -w method. This is a new Pixel XL I received from Google to replace a nexus 6p with a bootloader issue. I made the mistake of not attempting this before it updated from 7.1.2 to 8.0.0, or it may have been a different story.
So I have the the phone restored to 8.0.0 and was going to attempt root. But I didn't realize there are two slots to flash. I simply ran flash-all.bat and the phone came back up. So I guess I'd have to move the Sept security stock image over to the phone along with the SU, SU Config (which may not be needed if on 8.0.0?), and Su Hide. Then I boot up TWRP 3.1.1 and flash stock image to both slots, reboot, then get back into TWRP and run the SU, then SU Hide on *both* slots?
Thanks!

Run flashall.bat on the slot you are now in. Reboot to system
Back to bootloader. Switch slots through fastboot
fastboot --set-active=_b
fasboot reboot bootloader
Now you should be on the other slot
Flashall.bat
Reboot to system
Back to bootloader
fastboot boot twrp.img (latest)
In twrp put latest su or in my case magisk 14.2, twrp zip on device.
If you use su just flash it
If you use magisk. Flash magisk, flash twrp.zip and magisk again. With magisk twrp will stick.
Reboot and you are good to go.
If you want a kernel you have to flash twrp and magisk after again.

Thank you! I will be able to perform this sequence in a few hours and will report back. :good:

Ok. Will be in bed than. If you have any problems give me a PM and we can do it together via hangouts.

Update: I successfully flashed A & B, got to the step where I flash Magisk 14.2. It finished unmounting partitions, but when updating partition details fails, "failed to mount '/system' (device or resource busy)...done
It said successfully installed, so I flashed twrp to the boot image, flashed magisk again, and it is now rebooting endlessly. Wrong place to flash the twrp image I'm guessing?
EDIT: Just noticed your message, good night - thanks again. I'm working through it and will take you up on your kind offer should I not find success.
I did a 'flash-all.sh' on both A and B again, copying over my old phone, then will attempt to gain root by booting into TWRP 3.1.1, installing "SR3-SuperSU-v2.82-SR3-20170813133244", reboot bootloader, go into TWRP again and then install "UPDATE-suhide-v1.08-20170815171034"
EDIT #2: EDIT #2: Stable root achieved using newer versions of files "SR5-SuperSU-v2.82-SR5-20171001224502" & after booting, applying "UPDATE-suhide-v1.09-20171001222116". So far it has survived several reboots, so I'm hoping it's all good now.

Installed substratum theme, phone died on reboot. Can I backup data before reset?

Long story short installed substratum and it was working fine, had a navbar theme already running and installed another one. Few hours later rebooted phone and when it booted back up systemui crashed and it went into bootlooping into that over and over again. Now it bootloops a few times and goes into a recovery menu that only gives me the options to try rebooting again or a factory data reset.
The phone boots into bootloader/fastboot just fine and I can get into recovery but the only options I have are 'try again' and 'factory data reset' I know that FDR is basically my only option and so be it. BUT IF POSSIBLE I want to try and backup the internal data or at least as much of it as possible.
So, is it possible to backup any internal data with only having access to bootloader/fastboot.
I've spent over an hour searching to this answer but either I was searching wrong or simply was not able to find the answer. Pixel XL is 100% stock. Never modded, never rooted, stock recovery, stock latest official Oreo from OTA update.
So again. Absolutely no access to the OS. Only access bootloader/fastboot and a form of the recovery menu and I would like to somehow backup the internal data. I don't care about apps or any app data, specifically just the user data if at all possible. If not well then I'm screwed and that's that.

Hello,
Happened to me also something like this. The phone rebooted and the only option were those presented to you also. But, I pressed the "Try again". If this still doesn't work, when the device is rebooting, and the white screen appears, try and hold on to the power button until the moving dots appear.
Also, this didn't wipe anything on my device.
Hope this is useful to you.

Does nothing. Just reboots back into recovery. I've tried Try Again probably 100 times and nothing ever changes. Even safe mode does not work. The SystemUI is completely dead.
I'm 90% sure there is no way to fix the phone other than factory data reset and I'm fine with that. I just want to know if I can backup anything from bootloader/fastboot before I do that.

Have you tried using ADB to boot ( not flash ) a custom recovery, and from there to backup the phone, and after if it's possible, to use the USB-OTG to copy that backup to an USB memory stick?

Looking at the Substratum FAQ in the app it says that if you experience a bootloop you should be able to flash /storage/emulated/0/substratum/SubstratumRescue.zip in recovery and it should fix the boot loop.

As Matt already mentioned, there's a rescue zip file which comes by default with substratum. It's purpose is to remove all overlays which you've currently installed.
In case you don't have a custom recovery installed you can simply boot into twrp via adb (without having flash the recovery)

What if you're bootloader locked? Is there a way to recover from a bad overlay?

You could try to flash the factory image if you've unlocked the BL, just remove the -w from the flash all script

If you have checked the option to potentially allow unlocking your bootloader in dev-settings you can use fastboot to unlock your bootloader and boot into the bootable recovery image

Missing Recovery on Android 10

I just noticed after doing a clean install of the C3 factory image using -w that I am unable to boot to the stock recovery. It seems to be missing from my installation. Any ideas why I may be unable to boot to recovery? All I get is a dead Android logo with "No command" or it boots up my system after restarting. I've tried booting from the bootloader numerous times and never seems to work. Is it possible that the stock recovery was never installed? I did no perform a --slot all when installing Android 10 so maybe that's the issue? Any suggestions would be great as I can't seem to find a solution to this in the forums or Google searching. Thanks.

You have to go one step beyond the no recovery screen to see the recovery commands. If presented with an image of a broken Android with “No Command” printed on the screen, press and hold the Power button. Press the Volume Up button once. Then release the Power button.

Seems I can't even get to the broken Android screen now. In the bootloader if I select boot recovery it just boots my system and never shows the broken Android anymore. Very odd. I'm stumped.

I am not sure what you are referring to "boot recovery." Are you entering the bootloader in some way other than volume down +power? The option when using the up/down in bootloader is Recovery mode. That will get you to the broken android and no command. At worst though, you can flash boot.img and get your stock recovery/kernel back/unroot.

I can enter the bootloader via adb or with the power + volume down no problem. When I select recovery from the bootloader it boots to the Google logo then blank screen and seems to reboot again straight to my system. I may have to try to revert to the stock boot.img like you suggested and see if that solves the issue.

I get the same thing where it won't boot to recovery from the bootloader, but goes back to booting to system. It's because I'm rooted. Flash the stock boot image and you'll be fine.

OK, that makes better sense. You are pretty clearly in a bootloop. Just confirming the terminology. Flashing stock boot might get you out of the loop, but after rereading your initial message it sounds as if some info is missing. After the flash-all, did it ever get to the setup screen where you enter your gmail account name, etc. Did it get through that to the actual OS, and if so what else did you do that got you into the bootloop? Root attempt?

Ya my phone setup fine through all the initial setup steps as if it was a new device and the system works perfectly. I did root and install Kirisakura kernel but only after few days of using stock. Just noticed after setting everything up the recovery seems to be missing when I tried to boot into it. I may try and start from scratch again cuz obviously something got broken during the factory image installation using -w.

I missed the post by @jd1639 while I was replying. It doesn't sound like anything got messed up as a result of the -w. Because stock recovery is part of boot now, you just need to stay out of there unless you flash boot.img first. Not doing the --slot all wouldn't have any impact unless you install a custom ROM, an OTA or do a manual slot change. Since it was the first time I had done a completely clean wipe in a while when I flashed 10 (after custom ROMs, OTAs, etc), I actually did flash-all (with -w) to both slots. I did a flash-all on B and finished setup, and then booted back to BL, changed slots manually to A and did a second flash-all. Only after that did I start gettin gthe phone ready for daily function. Not sure it helped anything but my OCD, but it was fun to watch the fastbootd thing run a few times. :silly:

I never would have assumed having root could cause this issue.

Unlocked bootloader - boot loop after trying to put stock firmware back on

My telephone keeps booting to fastboot after trying to update TWRP.
I am trying to restore the original ROM (apollo_eea_global_images_V12.5.12.0.RJDEUXM_20220208.0000.00_11.0_eea) and I can get the rom installed through fastboot but the phone enters a boot loop cycle. It starts up, vibrates shortly then reboots.
If i press volume up it goes into the original recovery menu. I have tried clearing everything and even entering safe mode but the phone will not boot.
Am i screwed?
Thanks in advance.

I installed the Pixel Experience recovery and side-loaded the zip and at least have a working OS.
I must be doing something wrong with the stock mi10t

Now i sided the miui zip and its working agian. I think i have misunderstood the procedure. I thought you only need to install the rom with flashboot and that was it.
