Unable to root after OTA update

Hi.
Has any one been able to flash custom recovery after installing OTA and upgrading to 23.72-47?
I upgraded to stock version 23.72-47 via the OTA update way. And after that I tried using the fastboot method to flash twrp in bootloader mode. The command is execuded successfully but rebootin to recovery opens the stock recovery and not twrp. Any one was successful in flashing twrp after OTA update?

Just for the heck of it, have you tried just booting into TWRP instead of permanently installing, to see if TWRP will even load ok?

No. Will try.....
Aaaaah, yes. Now I recall why I was wondering the first time I tried to root the fastboot command was 'fastboot boot recovery recovery.img'.
I still wonder why the flash command does not work.. There is a clear 'OKAY' indicating successful flashing of the recovery. It surprises me as to where the recovery was flashed or written (if I have understood flashing correctly).

I had no problems flashing TWRP with "flash" command afterwards. My notes... http://forum.xda-developers.com/2015-moto-g/general/manual-ota-update-process-step-step-t3206049

Boot command worked
As an update I tried the fastboot boot recovery.img command and I could reboot and adb reboot onto twrp recovery mode. But when resorting to the volume button mode to recovery I again was presented with stock recovery.
I tried using the fastboot flash recovery command and it seems to have done the job. Now I am able to reboot to twrp recovery using both software and hardware ways.
What still bugs me is that why did not the flash commands work?
Any insight into this will help me understand the nuances of differences between booton and flashing o I have misunderstood them.

fastboot boot recovery.img=boot into recovery once
fastboot flash recovery=flash it permanently

Thank you, so what I too understood is correct then.
Bear with me but my question is, why the command of flashing the recovery did not work first time despite of the fact that the fastboot command terminal showed "OKAY"?
It worked when I used the boot command to flash and I could root it after that. But after booting and rooting, I was presented with the stock rom subsequently.
So, I used the flash recovery command this time around and it worked to lodge the recovery in place.
Not able to understand why the flash command did not work first time.
Appreciate any clarification or explanation

I don't know if it's same in Moto devices too or not but in Samsung there's a file named installrecovery.sh which replaces custom recoveries with stock on boot.
But once the device has been rooted it can be stopped from doing so.
Maybe this same thing happend with you.
Again this is just mere assumption keeping a samsung device in mind and may be completely wrong logic.

Try using a new usb cable. I have no idea WTF motorola was thinking, including that god-awful charger without a detachable usb. I've seen this problem happen several times, though. When the cable goes bad but still has the actual connection it may not transfer data properly...but since it's connected fastboot doesn't know the file never actually transferred so it reports that it's done.
I bought a 6-pack of Tronsmart USB cables from amazon for $10, and they're absolutely amazing!!! They're made with 20-gauge wires, which are far thicker than those that will come with the phone, no matter what OEM it's from. Fat cable means fast transfer speeds and a longer life, since it will take longer to fray due to its heft.
*** the deal I got is actually back. Last time it only lasted a day, so if you want it, I'd recommend hurrying!!

Stuck in Bootloader (Solved)

So i recently tried flashing a new kernel and for whatever reason my pixel 2 did not like that at all. Upon reboot after flashing it now just goes into the download mode where i have the option to reboot bootloader go into recovery and go into download mode. Normally not a big issue at all but this time when i go to load into recovery or load into Download mode its says Operation Denied. Upon a reboot or trying to reboot into safe mode it says ERROR: Slot unbootable: Load Error. Will ADB still work to flash this? not really sure what to do at this moment.
EDIT: Solved it by using Fastboot and flashing the stock firmware without the -w so far everything is back to normal....know to get that dern kernel again

First off, does fastboot recognize the device?

It does not under adb devices nothing shows up. In device manager it does show up as Android bootloader interface

ADB=system. Fastboot=boot. You can't boot your phone, so you're not in android, thus no ADB devices. Type "fastboot devices" and see if it's recognized.

Good news! So, your best bet at this point would be to re-flash your current factory image, with /w removed. If you still want that same kernel, flash it before Magisk.
Just out of curiosity, what method did you use to flash it in the first place?

It wipes all your data, that's why you remove it from the flash-all.bat script, unless you need to perform a full wipe. Telperion has an excellent guide for installing the lastest software, if you haven't already read it.
I've heard users having back luck flashing kernels in TWRP, as the kernel has something to do with recovery. I always use the method of booting the TWRP image in fastboot, use ADB to push the files to /tmp, and then do an ADB shell TWRP install of those files. TWRP, kernel, then magisk, in that order. I always reinstall all three, just to be on the safe side, and have never had any issues. Takes a little while, but not as long as redoing the whole freaking thing:silly:
Looks like you figured it out, before I finished my reply

Pixel 2 Magisk Bug won't take pin

Pixel 2 XL is soft bricked at the moment and I can't for the life of me think of what I need to do to recover it. I unlocked my bootloader and rooted when I switched to Pie, (I saw people we're already able to use Android pay on a rooted device again and I just couldn't help myself.) I installed twrp accidentally tried to flash TWRP not realizing I needed to temporary boot it and pushing the zip over erasing the recovery I proceeded to just fastboot it and carry on with the normal procedure with my phone. after getting Magisk installed I had my phone all set up until the next time I turned it on and back off again It said I forgot my PIN which I know I didn't I think this was because a glitch with smartlock I just setup so I go to my recovery and wipe the Dalvik cache, cache, Internal storage, and data and low and behold my phone bootloops never making past the final stage before it gets to the lockscreen. I go to Fastboot screen on my phone and my mac can't list my phone as a device in adb and now I am having issues getting back into recovery which I think might be because I am on the stock kernel my Fastboot screen on my phone says Product Name - Taimen, Variant - MSM USF:SAMSUNG(64gig) DDR:SAMSUNG, Bootloader version - TM220j, Baseband version - g899800253-1805232234, my Serial number, Serure boot - Yes, Device status - Unlocked, Vart console - Disabled, HW version - rev_10
I can't get it to stop bootlooping and just turn off.

Try flashing the stock boot.img with Fastboot. That might get you out of it. Since you did all the wiping I can't say for sure. However, when you were at the point where it wouldn't take your password, that's all that needed to be done. I ran into the same thing. It's a Magisk bug. Magisk gets flashed to the boot partition so flashing the factory boot.img will fix it. TWRP also gets flashed to the boot partition so if you flashed it too, flashing a factory boot image will get rid of that too. ADB won't see the phone while it's in fastboot mode. You need to use "fastboot devices". You can download a factory image if you don't have one and extract the boot.img from it. Put it in the folder your fastboot is in, and then open a command prompt (terminal? I'm not a MAC person) from that folder and type "fastboot flash boot boot.img" (without the quotes). Make sure you use download the factory image that's the same as what you currently have installed on the phone.

I stopped my endless bootloop! Now it says my device is corrupt and cannot be trusted and may not work properly when I tried to start it I couldn't get past the google screen. When I plug it into charge now it doesn't automatically going into a bootloop that can only be stoped by going into the fastboot mode or running out of battery, but the the charging symbol on the screen won't go away. I might have wiped system when I was in TWRP when I couldn't boot back after the first wipe. And I accidentally tried fastbooting Telstra img first. Anyway to get past this white Google screen? Also when I trey to go to recovery now it's the android laying on it's back with a red triangle and it says no command. Should I execute the flash-all script?

Downloaded the stock img files and ran the flash all .sh and now I am back in Android ready to mess something up again I could not thank you enough for your help I am so happy right now

Glad to hear you got it working again. As for the recovery screen that say no command, that't the way it works with the stock recovery. When you see that screen, press and hold power and volume up. That will get you into recovery. If you happen to try rooting again and get stuck in a bootloop or some such thing, just flash the stock boot image.. That should get you going again.

Magisk uninstall, boots twrp won't boot back into phone OS

I was downloading a OTA update the other day & in preparation I thought I would go ahead & uninstall Magisk. Magisk asked me if I wanted to restore images or uninstall I just uninstalled, not ever having made a image before I didn't know what it was talking about.
The phone rebooted once then booted again into TWRP, I can't get back into my phones OS.
Later I couldn't get back into TWRP so I had to boot using the fastboot commands in Windows. I was able to see & "Backup" the contents of my phone to an external drive.
Now how do I get back into my phone like normal?
Do I need to flash an image or I've seen other threads they wipe the data & there phone boots?
Please advise.
Thank you

First of all, no need to uninstall Magisk - unnecessary and waste of time.
Once in TWRP (fastboot boot twrp.img, or via your phone if you still can) - flash OOS OTA update (as that was what you were trying to do).
Then flash TWRP, reboot TWRP. Now you can flash Magisk again (so you get root, since you removed it for some reason).
Everything should be fine.

Unfortunately now I can't get the "fastboot boot twrp.img" to boot into twrp? FAILED authentication.
Now what?
Fastboot devices work & the reboot function works, just can't boot twrp.img. I've seen somewhere I can maybe force boot the device idk if it will work. damn

Sorry to hear. You are going to have to provide logs of what commands you are typing into terminal, and what is the output.
So are you in TWRP or not. I literally have no idea what is going on with your device or what you are doing.
Next time, maybe check guides in this forum of how to do what you are doing.
Randomly uninstalling/installing/flashing/issuing commands via terminal/random backup and restores/etc.... does not sit well with android devices.

I'll try another pc tonight.

If you can get back to twrp you need to flash magik to boot normally

Still can't back into twrp. Failedremote: failed to load/authenicate boot image: Load error.)
Tried a different computer. Tried deleting my fastboot files on PC then copying them from a backup thinking I modified the twrp image wrong thinking this unmotified version would work, still nothing.
Can I get some advice links to guides. Thank you.

ARE YOU SURE you are typing 'fastboot boot twrp.img' - BOOT, not FLASH!!!???

I'm now able to boot into twrp. Had to use fastboot --set-active=a. Worked great. Left it like that at home. I'm at work now.
What next?

I would start by reading forum page 1 information about what you are trying to do.
I already explained to you the order to flash to make things work.
If that is not enough, once again, go learn what you are trying to do (via the forum thread).
You will probably save yourself these types of situations in the future if you understand what you are doing.
Good luck.

Everything is FULLY Operational Thank You. What a experience but Ive learned.

[Help Needed] Semi Bricked - Remove substratum overlay or somehow backup my data

Hey Guys,
So my idiot brain decided to mess around with substatum themes after I updated and rerooted my OP7P. I rooted with magisk but forgot to put TWRP recovery on.
Anyways, got the phone semi bricked when applying one of the overlays. The phone boots and I can see my lock screen wallpaper but the screen is just flashing on/off.
I cant use the fingerprint or pin to get it. Is there a way for me to backup my pictures and data or somehow remove substratum?
Biggest problem is that for whatever reason, the update revoked my ADB authorization so it looks like I cant do anything with ADB.
If someone has any way to salvage my situation, please reply. Factory reset is my last resort due to no backup.
Thank You

Try booting into TWRP and using ADB there.

Well boot to fastboot. Flash twrp there and then reboot to twrp.
Flash rescue zip and you should be good to go

Problem is, I dont have TWRP recovery flashed, looks like it reverted to stock recovery after I updated. I rooted with Magisk which does not put TWRP back. I forgot to flash it after.
I also probably wont be able to do anything in fastboot either because the update removed the ADB Authorization and I am unable to accept it since my screen doesnt respond to anything, I will attempt this route though.
Edit: No go. ADB vendor key not set and I dont think I will be able to accept it on my device due to unresponsive screen

Fastboot doesn't need adb.
Switch off the phone, reboot to fastboot.
Then type fastboot boot (filelocation of twrp.img)
Then your phone will boot to twrp.
Flash rescue.zip.
If it is still a no go. Then use msm tool

Rebooted to fastboot, entered the PIN but Fastboot is a no go. Just keeps saying <waiting for any device> and nothing happens. Would that be because the authorization keys were not accepted after the update?
I am downloading the MSM Tool and will try that if I cant get it to work with fastboot. Will update if it works.
Thanks for suggestions

Ended up using the MSM tool. Did not know it wipes data and also put me back to Android 9.
Oh well, lesson learned. Gotta make monthly backups, make sure twrp is installed and working before messing around with substatrum.
Thanks for the help.
