TWRP not loading after flashing Oxygen OS 3.0

I'm having issues with my recovery after flashing the OOS 3.0 to the phone. My phone is working but when i boot into recovery, it stays on the page saying 1+ powered by android. Anyone else have this issue, or any ways to fix it.
I also tried re-flashing twrp, but i get "FAILED (Remote: dtb not found)" when i try to boot the recovery image.

After using this twrp, and flashed with cmd: fastboot boot recovery.img, I return in twrp-recovery.
So I restart (with disable and/or not disable to change the recovery). But after that I am in the same situation. It is possible to flash the same twrp for another time but that is not what we want
This even doesn't work when I restart to recovery.
Is there another possible solution?
Thanks in advance.

I had this problem and got the recovery working again with the modified version from above. Where did you get this? and what modification was needed? This is very strange. I never had that kind of a problem.
I flashed my phone back from OxygenOS 3 beta to OxygenOS 2.2.1 to get a working phone again and will now try to revert to the normal recovery again. From there I hope to get twrp 3.0.2.0 and cyanogenmod 13 to work.
UPDATE: normal twrp 3.0.2.0 works again. So my steps to recover from a brick with no accessable recovery to a working phone were:
1. flash modified recovery
2. boot into recovery
3. flash latest stable stock rom
4. flash latest stock twrp

Thanks a lot dude it worked for me
Keep up the good work guys.

What I did to get a working recovery:
1. flash modified recovery from first post in this thread with flashing recovery from pc
2. boot into recovery
3. flash latest stable stock rom
4. flash in recovery the latest recovery from first post
5. flash beta version Oxygen3
6. flash again twrp in recovery
7. flash superuser
8. disable replace recovery
All is well done.
Thanks for helping me mates!

I found out that it is enough when you:
1. copy modified recovery from first post in this thread to your phone
2. flash modified recovery from your pc to your phone
3. boot in recovery
4. flash the recovery you copied to your phone in installed recovery
5. restart with disable replace recovery
Thats enough to do the trick.

I am sorry to reply to an old post but I am unsure if other people are still having issues with this like I was. Here is some info from https://twrp.me/devices/oneplustwo.html :
"Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install."

Amazon Moto G4 bootloaders can't be unlocked?

I've followed a couple tutorials of that explain how to unlock Motorola's Moto G4 bootloader. This seems to be the "official" one from Motorola:
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-b
I copied part of it up to where I get stuck. Here it is:
Put your device in fastboot mode (power off, then press the power and volume down buttons simultaneously).
On your desktop, open a command prompt or terminal, and go to the directory where you installed the Android SDK tools (or make sure fastboot is in your $PATH)
At the prompt, type $ fastboot oem get_unlock_data
The returned string will be used to retrieve your unlock key.
Example: On a Windows Desktop, the returned string format would be $ fastboot oem get_unlock_data
(bootloader) 0A40040192024205#4C4D3556313230
(bootloader) 30373731363031303332323239#BD00
(bootloader) 8A672BA4746C2CE02328A2AC0C39F95
(bootloader) 1A3E5#1F53280002000000000000000
(bootloader) 0000000
****************************************
OK, so I just bought a Moto G4 for $125 on Amazon's prime day. This means that it has ads on the lock screen. I'm OK with that. But I think they also made the locked bootloader unlocakble as 3 times I've gotten this from a Windows machine in ADB mode:
(bootloader) Unlock data:
(bootloader) 3A45210407248602#
(bootloader) 5A59323233433246534C004D6F746F2047200000#
(bootloader) 1095EFAB6000EDC14660539C503A04F7900B9A01#
(bootloader) 9F93C800000000000000000000000000
There should be numbers in that first Bootloader line and then Motorola says:
You're device does not qualify for bootloader unlocking.
Has anybody else had this happen? This is my second time doing this to a Motorola phone and the Moto g2 was a snap! I was hoping to install a custom recovery like TWRP so I could get a nandroid backup while everything is new

Do u have the Amazon moto g4?

I do and I unlocked my bootloader and rooted the phone already.

Yes I have the Amazon G4

Well, these posts gave me hope that I was repeating the same mistake and I was. Forth time worked to unlock the BL. I was deleting the # signs at the end of each line. That was the mistake. It should be this from 4 lines:
3A45210407248602#5A59323233433246534C004D6F746F2047200000#1095EFAB6000EDC14660539C503A04F7900B9A01#9F93C800000000000000000000000000
Now I'm trying to boot into the TWRP image I flashed with fastboot and fastboot gave me errors about it not being signed so I'm not sure it worked. Where are people here getting the Moto g4 TWRP images? I went here:
https://www.androidfilehost.com/?w=...23bf15e9165ccc3b437c48af2047195d3fae863dca817

This is what I get when I try to flash TWRP now and then reboot into it with adb:
C:\Users\Huntz\Downloads>fastboot devices

Just FYI, Motorola's bootloader unlock website has a webtool that you can use to clean the output of get_unlock_data, so you'll only get the relevant info. Copy-paste the raw code into the tool, hit clean, copy paste the output into the unlock code line on the website, submit.
Regarding TWRP, yes I think everyone gets that "Image not signed or corrupt" message. Also, you can't "adb reboot recovery" from fastboot. Just flash it via fastboot, reboot into fastboot, then go into recovery.

Maybe it did install twrp OK since it still boots into the original stock ROM OK. How do u get into twrp with the buttons on the phone?

Boot into fastboot (press and hold power + volume down, let go when the bootloader screen shows up), press down on the volume rocker twice, and it'll say "recovery mode" on the screen. Press power once and it'll boot into TWRP.

Something's wrong then. I get to the fastboot screen OK but when I go into recovery it says your device has been unlocked and can't be trusted. It will reboot in 5 sec and then I see a dead robot.
EDIT
it does boot OK into the stock ROM from there if u do nothing for a minute or two or if u just hold in power button for 15 secs to get a black screen and then release the button and hold it 4 secs to get a normal boot

Sounds like TWRP didn't flash correctly, or maybe was a bad download (can download directly from TWRP's website here: https://dl.twrp.me/athene/). Reboot back into fastboot and try flashing TWRP again (you might also want to try renaming it to recovery.img, so the flashing command would be "fastboot flash recovery recovery.img").

I'll try again later today-hopefully it works and thanks for the link
I'm gonna try doing adb in Linux too.

When u reboot now, do u get a 5 second delay screen that says your device has been unlocked and can't be trusted?

Yes, that is normal for devices with unlocked bootloaders. You can get rid of it by rebooting into fastboot and following this guide: http://forum.xda-developers.com/showpost.php?p=67031810&postcount=5
(if you don't have mfastboot, you can use plain-old fastboot as well)

I'm puzzled-the md5 on twrp was right and I unlocked the BL OK. I'll try it in Linux later and see if it takes.

Might be worth trying another USB port or even another cable. Some people have issues when trying to flash things on a USB 2.0 phone plugged into a USB 3.0 port.

About how much time should it take to flash twrp? I don't think it even flashed anything yesterday because it was too quick.

It is almost instantaneous. As for the booting into recovery and seeing the dead robot, that is probably due to the fact that the phone tries to re-write the recovery when you reboot automatically. Just flash the twrp.img, and then go to recovery from the bootloader without rebooting and you will be fine; just make sure you have whatever you want to flash (e.g. supersu) on your device storage when you get there.

Sounds like a plan! What's the md5 on the supersu file?

Unable to flash TWRP on Moto G4 Plus

I had previously rooted my Moto G4 Plus and used multiple custom ROMs before switching back to Stock firmware.
Now, I'm unable to flash TWRP on my device. Any attempts to flash TWRP ends up with the following error:
Code:
reboot bootloader
mfastboot flash recovery twrp.img
target max-sparse-size: 256MB
sending 'recovery' (12530 KB)...
OKAY [ 0.406s]
writing 'recovery'...
(bootloader) Image not signed or corrupt
OKAY [ 0.203s]
finished. total time: 0.608s
Any further tries to reboot via adb commands results in the following:
Code:
adb reboot recovery
error: device not found
adb reboot
error: device not found
adb reboot bootloader
error: device not found
The device says the bootloader is unlocked while rebooting. the ID field shows 'bad key'(I feel this is weird).
Can someone please help me with this?
Thanks

It has got flashed correctly as you got "OKAY" at end of command. Try to boot into recovery and tell us what happens.

1) That TWRP message of 'Image not signed or corrupt' is normal, since the TWRP custom recovery is not signed. After you see the [OKAY], reboot to recovery directly to fix the TWRP, else the stock recovery will overwrite it. Afterwards, you can boot as normal.
2)If you're still in the bootloader on your device, adb commands do not work - you need to use fastboot commands, or use your device volume keys to select 'Start' (to boot to system) or 'Recovery mode' (to boot to recovery) and press the power key to select. Of course, in this case, after flashing TWRP, you'll want to select 'Recovery Mode' in your bootloader and press the power key. This should then boot into TWRP.
If you find yourself in the bootloader in the future, then 'fastboot reboot' or 'fastboot continue' (both commands to be used without quotes, in the ADB terminal) may get your device rebooting to system.
3)ID Bad key is normal with an unlocked bootloader, on subsequent boots this may change to ID:N/A

Hi @echo92,
Thanks for pointing out what I was doing wrong. I now realize that the TWRP recovery was being overwritten by stock recovery and I didn't know adb commands don't work while still in bootloader mode.
I did boot into recovery mode from the bootloader (using the volume buttons from the phone) and it worked.
And the ID: bad key is also gone and now it shows ID: N/A.
Thanks again for your help!
Regards

Pre flash validation errors suggest that your bootloader is locked (i.e. you have not unlocked your bootloader, or it has been re locked). Can you confirm your bootloader is unlocked, e.g. if there is a warning screen on boot saying your device is unlocked?

That TWRP won't work, if it's for Titan. The codename for Moto G4/plus is athene, only TWRP images specifying athene in their name will work.

Moto G boots only into TWRP

My XT1625 has an unlocked bootloader and TWRP installed. Today I got a notification that the Sept security patch was available so I downloaded it and tried to install. I was paying attention until I noticed it booted back into TWRP and does it everytime so I guess accepting and installing that patch was a no-no. I got it to boot into Android from instructions in another post.
Can I locate the patch in TWRP and flash it from there? Btw, I did notice that the patch was only 49MB so it clearly wasn't the entire Nougat ROM.

You cannot flash an official OTA update. You need to be on official recovery for this. Have a look at here, same question https://forum.xda-developers.com/moto-g4-plus/help/luck-moto-g4-plus-flashable-logo-bin-t3701652
For update its advisable to use the full stock rom to be flashed with fastboot like this one https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138

Is this going to wipe my system like a factory reset? If so, can I just restore the backup I made after I installed TWRP initially? Or just do a factory reset?

@lmacmil ignore it, use both commands then try to boot.

Don't use it if you are thinking to just run script and not to flash... since it has "erase modemst1 & 2" it will erase modem, but will not flash fsg/modem, also "erase data" will wipe everything on phone.. this can put you in trouble..
Instead of doing this, as strongst said in his post, flash complete firmware, see the link for september's update he gave in his post.
Then move everything from your phone to PC (images / video/ etc)
Then flash firmware...

Still boots to TWRP. Maybe this is the time to move to LineageOS 14.1. I was going to wait until 15 was stable but if I'm going to lose everything, I might as well get more up to date.
This seems to have killed my cell signal too. Just noticed that last time I booted to Android.

Did you flash complete stock ROM ?
Move your files to External Storage then try it.

I decided since I would have to reinstall all my apps anyway that I would flash LineageOS 14.1, which I did. I did the appropriate wipes (data, system, cache, Dalvik/ART), then flashed the latest nightly and Gapps. It was successful but it's still booting into TWRP and I still have no cell service. I thought that a complete wipe and installation of new ROM would correct those issues but it did not. And since it didn't, I'm not confident that flashing the stock ROM would either but unless there's something else to try, I will do it. One concern I have is I have a plain G4 and the ROM is for the G4 Plus. My build was NPJ25.93-14.5 and I think the Plus build is NPJS... Not sure if that makes a difference.
Maybe I should restore my original Nandroid backup first and see if that fixes things.

NPJ25.93-14.5 was for Amazon variant if i am not wrong.
I don't know but in past that two commands [fb_mode_set and fb_mode_clear] worked fine for this problem.
Try this thing, [reboot to bootloader and flash TWRP but with fb_mode_ commands]
- fastboot oem fb_mode_set
- fastboot flash recovery twrp(name).img
- fastboot oem fb_mode_clear
If this too doesn't work, then you have to find correct firmware for your phone and flash it..
EDIT: for easiness to find correct firmware, restore backup, then see "about phone" for build number, it will help to find firmware..
EDIT-2:
I found 2 firmware of version you said,
But one says Amazon and another doesn't. You have Nandroid, restore and check your phone build..
Then go for following one correctly..
AMAZON : Click here
Non-AMAZON : Click here

Mine was the non-Amazon version. See attachment. The software channel was "retus" and the baseband version also said "ATHENE_RETUSA_CUST" The Amazon version software channel is amz.
I was able to get the bootloader unlock code from Motorola and they don't allow the Amazon versions to be unlocked.
I'll try your suggestions. Thanks for your continued help.

=================================
Not sure why I'm getting the bootloader error messages but I backed up just the bootloader recently so am going to restore that and see what happens.

@lmacmil that "not found" is ignorable, just check you get "OKAY" after one command ends... Since GPT and Bootloader commands got "OKAY" they are flashed successfully..... Go for complete firmware...

I guess I need to bite the bullet and do this. It will install stock recovery and erase TWRP, right? If that's the case, and I don't relock the bootloader, will I be able to accept the OTA update? Or does an unlocked bootloader prevent OTA updates?
Last question: I just extract the firmware .zip file to the same folder where fastboot and adb reside? Then type the commands one by one (or copy/paste from the script shown in the thread about flashing stock firmware.)
Thanks again.

Yes, it will install stock recovery, you will have to install TWRP again.

It will be fine, You will have successful installation with unlocked bootloader too, no need to lock back..

You did right, that's why there is "OKAY" when command end, see your own post where you asked for "not found" error... Keep Going..

Success! Just flashed the stock Nougat ROM and as soon as it booted up, I let it download and install the Sept security patch. I am now on NPJ25.93-14.7.
Thanks again for all your help.

LG h918 in bootloop with only fastboot available. Help!

Hi All,
I just followed the instructions to root my h918 and then successfully updated to h91820h. I then used the TWRP app to flash twrp, and the Magisk app to update Magisk. After that I rebooted from the Magisk app, and now my phone is stuck in a bootloop. I cannot get into download mode, or recovery mode, or the system. I can get into fastboot mode by trying to go into download mode (holding the volume down and plugginto a USB port ot the laptop.
It seems that T-mobile removed any commands from fastboot that will help me. If I try to "fastboot reboot emergency", it just bootloops. If I try fastboot boot a twrp image, I get:
Code:
fastboot boot twrp-3.4.0-1-h918.img
downloading 'boot.img'...
OKAY [ 0.667s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.686s
The command "fastboot reboot bootloader" boots to fastboot. The bootloader is indeed unlocked, but it looks like I'm stuck, because the LG fastboot doesn't allow anything to fix the brick.
Code:
$ fastboot getvar unlocked
unlocked: yes
finished. total time: 0.020s
I'm not finding any hope or help on Google. It seems if I can't boot into twrp or download mode, I'm toast, and I can't figure out how to boot into anything but the bootloader.
Does anyone have any suggestions on how to bring this phone back from the dead?
Thanks,
Rob

How are you trying to boot into download mode, are you trying to do it via fastboot or the hardware buttons?

im having the same problem, i dont have download more or twrp now, all i have is fastboot

i am going to assume going into download mode through fastboot is the only option for the two people posting for help here. from what i see from the posts, both hardware buttons sequence , or the plug in & down volume are the ONLY way to get to fast boot.
and fast boot is the only thing available on the phone.
i have labeled that a soft brick .
i asume one of the two help seekers have used the magisk 20.2 trap?
the release proved to be a problem , there is a tutorial on how to fix it.
i will go look for that and try to edit it into my responce later.
for now, are the two seekers already acomplished in this procedure?

ok i found a way to get into twrp (if ever installed)
1- turn off your phone
2- hold Volume Down + Power button until you see the LG logo
3- When you see the Logo release the power button while still holding the volume down and immediately after release press power button 3 times.
4- you will see a factory reset screen, press yes twice and it will go to twrp.
