Unable to install TWRP recovery on Zenfone Max Pro M1 - Asus ZenFone Max Pro M1 Questions & Answers

Hi all,
I have this X00TD model, and I recently updated firmware to WW-16.2017.2002.061. The phone has Android recovery, and I want to install Lineage OS. Whenever I try to install Lineage, I get the error 21 "signature verification failed". I read somewhere that I can disable the signature check in TWRP. But TWRP fails to install, whatever I try. I tried 3 different unofficial versions of TWRP (as my phone model has no official version of TWRP) and in fastboot, when I give the command "sudo fastboot flash recovery <filename>.img", nothing happens, and the process just freezes, and I need to kill the terminal to end the process. I have Ubuntu 18.04 installed. ADB and fastboot seem ok. When I type "sudo fastboot devices", my phone entry comes up. Any help would be welcome. I don't have windows os.
Thanks.

If you can't install TWRP on pie, try reverting to Oreo with AFT and then flash TWRP in fastboot. Also make sure you have unlocked the bootloader whether by the official tool or the unofficial method. THIS WILL DELETE ALL DATA SO BACK UP.

Thanks arko. Is there Asus Flash Tool available for Linux also? Will try and revert. Thanks :svetius

Tried reverting to Oreo with AFT, doesn't work. I installed windows 10, but fastboot doesn't work.
#fastboot devices gives me no output. I have the Oreo zip file, any alternate way I can install it? As you mentioned, there seems to be an issue with the pie ROM on my phone. Any way I can downgrade to Oreo using windows/Linux?

Windows 10 ? Its bcuz Driver Signature Enforcement
Disable it and reinstall adb and fastboot drivers, it will work for sure.
Windows driver security wouldn't accept drivers without proper Signatures,so like i said, just disable it and you are good to go.
:good:

​
Tried steps you mentioned, doesn't work. In fastboot mode, #fastboot devices gives me no output. Looks like my pie ROM is buggy. Basically, I need to install lineage on the phone.

Hi all,
Finally got everything done in about 5 mins I booted up Ubuntu Mate (32 bit) on my other laptop, and found I'd already installed adb and fastboot on it from the repositories (not from google). I booted my phone in fastboot mode, and tried the #fastboot devices command, and voila, my phone got detected! After that, it was a matter of a few minutes, following the installation instructions (of twrp and lineage) from the lineage website. Thanks for all your inputs and help
P.S: I realised (again), after more than 2 decades, that windoze mighty sucks lol.

Doogee X5 Max Pro Root Recovery OTA

******************Root Recovery Doogee X5 max pro*******************
Your waiting Time IS Now Finished Here is Complete Guide to Root Doogee X5 Max Pro install twrp And More,
Hit :good:
ADB & Fastboot
Before doing most things mentioned below you will need "adb" and "fastboot" installed. Two of your options are to install the Android SDK Tools or the Minimal ADB and Fastboot tool. If you are somewhat new to this I highly recommend the second one. Go here, download the latest version (1.3.1 as of this writing), and install it. When setup is complete you should have an icon for the Minimal ADB and Fastboot tool.
Note: I highly recommend you add "C:\Program Files (x86)\Minimal ADB and Fastboot" to your PATH variable in Windows. This way you can open a Command Prompt anywhere and use adb or fastboot.
1) Unlock Bootloader
Power on the phone and skip through all of the setup options
Go to Settings -> About device
Tap Build number five times to enable Developer options
Go to Settings -> Developer options
Enable OEM unlocking
Enable USB debugging
Plug the phone in to your PC and authorize it
Open a Command Prompt
Type adb reboot-bootloader
The phone should reboot and in a very tiny font at the bottom you should see => FASTBOOT mode
Type fastboot devices to verify that your PC sees it correctly
Type fastboot oem unlock
Press Volume Up to say Yes and wait for this to finish
Type fastboot getvar all and look for (bootloader) unlocked: yes
Type fastboot reboot
You should see your phone reboot a couple times as it erases the phone
Install twrp-
Power on the phone
You can configure your phone now or just skip through all of the setup options and do that later
Go to Settings -> About device
Tap Build number five times to enable Developer options
Go to Settings -> Developer options
Enable OEM unlocking
Enable USB debugging
Plug the phone in to your PC and authorize it
Open a Command Prompt to wherever you extracted the .img file
Type adb reboot-bootloader
The phone should reboot and in a very tiny font at the bottom you should see => FASTBOOT mode
Type fastboot devices to verify that your PC sees it correctly, rename twrp to recovery.img
type fastboot flash recovery recovery.img to flash recovery
Type fastboot reboot
Rooting-
Download BETA-SuperSU.zip and save it to the phone's internal memory or an inserted microSD card
Plug the phone in to your PC
Open a Command Prompt
Type adb reboot recovery
You should now be in twrp. Go to Install zip, find SuperSU.zip, and install it
When it finishes go to Go Back -> Reboot Phone -> No
Once the phone boots up launch SuperSU and configure it as you like
Other Solutions-
i have doogee x5 max-s (i geuss limited editon in algeria ) with mtk6735 . i do evrything and all steps but when i reboot to recovery mode i have ( no command ) in the screen .... how to fix that ? sorry for my ****ty english XD
I had the same Issue but i have found a solution!
After you have flashed the twrp recovery, dont reboot the phone! the "recovery.sh" will replace the twrp on every boot!
Just pull off the battery after flashing, disconnect usb and put the battery back in to the phone.
Now get in to the recovery by pressing volume up and power button together until the select bootmode menue appears.
select recovery with the volume up button and enter with the volume down button.
and now you should be in the twrp main menue.
i hope it works for you too!

It does not work from step 12, all the drives are correctly installed and windows recognizes the cell, the recovery image is in the internal memory and also in the sd but of the error "can not load Recovery.img". I tried all the tutorials on the net to do root and nothing worked.The flash does not recognize to pass the recovery also the installed drivers because windows recognizes the cell phone.

use sp flash tools to flash recovery, scatter also added with twrp
Flash does not pass the file in the download only option, the process does not start. I reinstalled ROM by firmware mode all ok, but the process of passing recovery on command 12 and 13 of the error message. I manually copied the recovery to the sd and internal memory but also from the error. Does not find the file speaks that it is not a command found.

Until today I could not do root on x5 max pro. In the method below even downloading the twrp when starting with the power + volume down button start with a menu in Chinese and if you start with volume up + power goes in the default recovery mode.
Same as Pitro1 I am on 16.01 update and I cannot install twrp no matter what I try.
I tried x32 and x64. I tried rebooting directly on recovery or first load system and then adb reboot recovery. I tried to format all first (now I lost my Imei and so on lol). I downgraded and updated again. Downgrading works only with 26.12 version. All others are giving me Colorado lines on the screen and nothing else...
OEM unlock, file transfer, adb, fastboot, drivers detection, are all working good. Only I cannot install twrp...
Also I cannot write nvram nor with SN Writer 2.1504 nor with Imei & SN Writer 1.7.2, MetaAP mode fails all the time...
I'm just about to send it back...

How old is your phone and what build version was it at before you started? Because this doesn't work on mine. Which of the "Android 6" ROMs did you flash to start with as I've tried flashing mine back to an earlier one in case it's something with the later stuff that my phone has come with but they either don't make a difference or they won't even boot.
I tried the method in the first post here and the phone wouldn't even boot (switch on and you get the Doogee logo in silver for a few seconds then it reboots and does the same again). I had to flash the stock ROM from NeedROM to get it working again.
I've tried flashing TWRPx32 and x64 available NeedROM both with SPFlash tools and with ADB. Generally flashing it with ADB from the command line leaves the phone in that boot-loop. If I flash it with SPFlash when you try to boot into Bootloader afterwards you get the Doogee logo in silver for a few seconds then it seems to reboot again on it's own and boot normally - you don't even get the menu to choose Fastboot, Recovery or Normal. From then on trying to boot to the Bootloader gives you the menu but choosing Recovery gives you the standard recovery.
It's almost as if something is overwriting the recovery partition with the original after I flash TWRP onto it.
Anyone got any suggestions about where I might be going wrong or a way around whatever additional security they might have put in there?
Hi. I have tried to root my x5 max pro with flash tools to load TWRP, but it always restarts normally and the TWRP does not come out. I found you and I started to try this method to load the TWRP. Does everything good, unload bootloader and load recovery, but loading the TWRP gives me error .:
Device unauthorized.
This adb's $ ADB_VENDOR_KEYS is nor set; Try adb kil-server if that seems wrong
what I do?
rooting X5 Max pro in Ubuntu 16.04
Hi all, this is my first china phone and I basically bought it only to experiment, I'm a linux power user but this is the first time I 'play' with an android OS.
thanks to multiple guides and posts on this and other forums I'm getting somewhere and learning a lot about how to manage an android OS, I'm sharing a bit of info I unovered about doing this under ubuntu but I'm also stuck and in need of guidance, please help me.
Linux specific issues:
I'm running ubuntu 16.04 LTS, installed fastboot and adb tools from ubuntu repos, with these tools and no other modification to my system I could follow the tutorial on how to unlock the OEM bootloader with adb and fastboot.
accordingly to this post about SP flash tool in linux you might need to blacklist a modem manager module in order for SP flash tool to connect to the phone, you also need to install usb development tools (package libusb-dev) and check through dmesg that your linux OS can actually properly read mediatek usb devices.
After following the above mentioned instructions (both the linux sp flash tool tutorial and the bootloader unlocking howto) I could get SP flash tool linux (multiple version) to see the phone after you connect it while SP flash is downloading the new recovery image and flash it with an ok message.
If you get stuck with a BROM error 1013 remember to start sp flash tool with root privileges.
Phone specific issues:
I can get SP flash tool to flash my phone recovery with an ok message confirmation but the phone keeps rebooting with doogee recovery and not twrp. I'm on the newest stock ROM update (20170116) as of current post date. I've been using 32 bit TWRP images from multiple sources and linux version 5.1620 of spflash tool from their website
so my questions are as following:
1) after reading other posts I think I might have to play with different versions of SP flash tool and TWRP until I get the right combination, I think I might be using 64bit spflash tool for linux to flash a 32bit rom or something like that, can anybody confirm precise version number of the stock rom, TWRP and SP flash tool that worked out for you?
2) should I try to install the whole stock ROM posted in this chinadevices thread before trying to flash only TWRP recovery? please also check the linked thread for multiple custom ROM being ported to this phone, please also note that the full stock rom this poster uploaded (it's in the "all firmware" link) contains another flashing tools with chinese instruction called MultiDownloadTool.
www.china-devices.com/forum/index.php?threads/doogee-x5-max-pro-mt6737-custom-roms.20527/
3) I don't have access to a windows installation right now, but I do have a Win10 VM under Vmware workstation 12 pro, so I could try windows version of sp flash tool, do you guys think that USB passthrough would work?

Same here. May a work around would be finding out the oem commands in fastboot. I have seen a tutorial to get them, but you have to be root: https://www.xda-developers.com/how-to-discover-hidden-fastboot-commands/
I search a simple method
Why all so complicate? I am searching for a simple way to root.
For my old Doogee X5, I discovered just
update-ROOT-DOOGEE_X5.zip
Copy the zip to the micro-SD-card
Settings -> Phone info -> Update -> menu "update local" -> choose zip from micro-SD-card.
Start update.
That's all!
Now I search for such a simple solution for my new Doogee X5 MAX pro.
I do not want any methods with "volume down power", because my X5 MAX pro has the menus after "Volume down power" start in Chinese language.

Hi there,
I just tried the first file you posted, (twrp-x32-rom), and this one works for me after all previous attempts to boot up TWRP failed. Thanks for the link !
What I had tried before:
I have a relatively new X5 Max Pro, which I ordered a week ago. I updated the firmware to the newest version (20170116) using the OTA update function.
Then I tried to flash TWRP using the files from "needrom.com" which seem to have worked on older versions of the phone/firmware, but did not work for the newer versions.
I tried 32bit and 64bit TWRP versions and flashed them with SP flash tool, but when pressing Vol+/Power the phone would not boot into TWRP recovery. Insted, when selecting "Recovery" from the boot menu, the phone would show the Doogee logo in silver, then blink once, then boot up normally. When repeating this process, then phone boots into Stock recovery, indicating that the TWRP I flashed was replaced by stock recovery.
However, I just flashed the recovery.img from "TWRP LATEST" (the first file posted by Neaw) with SP flash tools and was finally able to boot into TWRP. I installed the superSU-zip 2.79 included in the link, and I am now rooted. Once again, thanks for posting this :good:

Huawei P9 lite VNS-L21 Massive Fail. Please help me out

Okay let me explain situation...
I wanted to unlock bootloader,install twrp, root it and install custom rom
I did unlock bootloader with SKRToolHuawei and it was pretty easy,also I installed twrp, then I installed SuperSu in my phone and everything was fine.
Until i dowloaded wrong version of CM 14.1, being a massive noob i though i could change my android 6.0.1 to 7.1 and i got the wrong gaps. In the tutorial it said to wipe cache,dalvid and system. Once i deleted system and got a fail error i realized what I have done and tried cm 13 (Meticulus) and again i got an error message saying that i need twrp version of meticulus.
So I dowloaded that version tried to install with adb using command:
1.Fastboot reboot bootloader
2.Fastboot flash recovery (In the tutorial it said its going to replace old version of twrp so I don't have to delete it)
And I rebooted my Huawei and it does't have a custom recovery for some reason. Now SKRToolHuawei and adb does't see my device and I'm in panic because I don't know what to do: crying::crying::crying:
Nothing works for me and I really need my phone.
Please help poor man out :crying:

what am I missing? adb sideload twrp fails

I am following this guide here to root oneplus 6t (european variant), 9.0.5 Android:
https://www.xda-developers.com/onepl...otloader-root/
bootloader is unlocked and I can see there is a positive connection between phone and PC by checking the output on adb devices and fastboot devices. both work as intended.
the problem is that when I try to adb sideload, it says that I need version 1.0.32. so this means I cannot flash the custom recovery.
any tips? been looking online for quite some time now and cannot figure out what to do anymore. where can I find this 1.0.32 adb version?
I am a long time user on nexus 5 and just bought this phone, want to root it aswell. (note: this does not mean I have high level of knowledge on these types of hacks, just wanted to have this clear.)
Are you trying to boot or to flash the recovery from adb ? If you're trying to install the recovery from adb it wont work, on a/b devices the recovery is part of the boot image wich needs to be patched, boot twrp.img and then get the bluespark twrp zip and flash it.

I can start the twrp, the problem is when I go into adb sideload and try to flash it. on pc is says "error" and on the phone it says I need to get adb 1.0.32. I am trying to flash that bluespark recovery with no luck.

You need to flash the zip from within the recovery that you booted using adb, not sideload it.
I already tried that, copied the files to the phone but when I try to access them through the bootable trwp, I cannot access them.

Can't install TWRP on OP6T

Hi - I am trying to reinstall TWRP on my OP6T after upgrading to OOS 10.3.0.
I am running Minimal ADB and Fastboot v1.4.3 on my Win10 PC. I have connected my phone to my PC, and entered Fastboot mode. The OP6T is detected when I do a fastboot devices command.
Next, I try doing a temporary Recovery Mode boot into TWRP with a fastboot boot twrp-3.3.1-1-fajita.img command. This is where I run into a problem ... While the Minimal ADB and Fastboot window says that the TWRP image was sent to the OP6T, I am still stuck on the Fastboot screen, and the phone is locked up and doesn't reboot the image.
What is going wrong?

Thanks, @jp0469! This helps a lot!
Just to be clear (and to get to a successful conclusion without a bricked phone), I won't be installing a TWRP installer ZIP file after booting into this TWRP image (The old style method), but instead installing the same TWRP IMG file as a "Recovery RAM Disk", correct?

Need a little more info before you proceed.
I know you said that you're currently on Android 10.3.0
Are you rooted with Magisk? If not, are you planning on rooting?

I was rooted with Magisk, but that got lost when I did the 10.3.0 update. Definitely planning on TWRPing and rooting again, as long as it's safe.

Stick to good old ones...
Once booted in twrp via fastboot flash the installer zip. It has always worked and will always. Always latest version. And flash Magisk after.

Put the latest Magisk zip and TWRP installer (zip file) on your phone's internal memory if you don't already have them there. Now you can fastboot boot the TWRP img file (Q version). Next flash the TWRP zip to permanently install TWRP into recovery. Reboot back to recovery to make sure it worked and then flash Magisk to re-gain root.
Reboot
Thanks, guys - The only reason I asked about the alternate "RAM Disk" method was because it was listed as the installation method by the developer on the link that @jp0469 provided earlier.
I'll try the old-fashioned method, since y'all say that it works OK.
I have a brand new hp windows 10 PC and a new op6t converted to international version. Running pie latest oxygen os. I need to get minimal adb fastboot installed so I can install twrp and root. Ik it's a little different process to get twrp on 6t but I need some help. Can someone provide me with the correct fastboot to install

I always install the latest directly from Google. There is a link on this page to the latest version of Windows ADB and Fastboot. Just unzip the file you download into a directory of your choice.
Everytime I try to boot twrp It says waiting on device. What's that mean

Hi - I am trying to reinstall TWRP on my OP6T after upgrading to OOS 10.3.0.
I am running Minimal ADB and Fastboot v1.4.3 on my Win10 PC. I have connected my phone to my PC, and entered Fastboot mode. The OP6T is detected when I do a fastboot devices command.
Next, I try doing a temporary Recovery Mode boot into TWRP with a fastboot boot twrp-3.3.1-1-fajita.img command. This is where I run into a problem ... While the Minimal ADB and Fastboot window says that the TWRP image was sent to the OP6T, I am still stuck on the Fastboot screen, and the phone is locked up and doesn't reboot the image.
What is going wrong?

press volume down,up and power button same time for 10sec your phone will boot to bootloader mode.
After doing the fastboot boot twrp-3.3.1-30-fajita-Q-mauronofrio.img in Fastboot Mode, I installed twrp-3.3.1-30-fajita-installer-mauronofrio.zip in the booted TWRP Recovery Mode, and everything is working fine again.
Thanks, guys!

Google Pixel 3a (sargo) brick - error boot prepare

Hi,
Today I wanted change my recovery. I had the Lineage OS recovery, but i was trying to install the twrp recovery.
So, the guide of twrp says that you should boot the twrp via fastboot boot twrp.img and install via the booted twrp. But I mistaken the command and I wrote fastboot flash boot twrp.img, I tried to reboot and the device booted himself in fastboot with the enter reason "error boot prepare" and I can't boot into the system or recovery.
I tried to flash the official image downloaded from the Google Developers website, but when i run ./flash-all.sh, console get stuck. I waited for about 15 minutes but nothing. I tried even the official Android Flash Tool but after 10 seconds it says "Your device stopped responding. You may have to select restart in the bootloader menu in order for it to be recognised again."
Does anyone know how to help me? Thanks in advance.

Yes, I wrote in the post, I tried both the command line tool and the chrome version. Btw i'm on linux
Okay so, I fixed.
For anyone who will have this problem you just need to flash official Android 9 and next Android 10. Only with Android 10 you can use fastboot flash boot recovery.img (you can't use twrp in android 10 with the Pixel 3a)

It depends if your pc were authorized, if it was, you can use fastboot to flash the stock version of Android 9, just running the flash-all(.bat) script.

I'm not certain I understand what you mean by PC authorized? I'm using a Windows 10 tablet. When the phone is attached to the computer it sees it as a device that can be disconnected through USB.

I just had an encounter with this. I was rooting my device (Pixel 3A) and messed up my partitions through accidentally attempting a downgrade which broke all my ****. I was unable to easily reset this device to factory, so it took me several days to figure out and root. I'm getting better though as a hacker, because a year ago this would have taken me a month.
I was able to enter recovery mode (lying down Android, NO COMMAND). From this recovery mode, adb devices -l recognized my device, although I was unable to get a shell.
At first, ADB was telling me the device was authorized, but I messed with a bunch of other stuff (tried to flash a bunch of different partitions and monkey around in general trying to install Magisk) and then ADB started telling me it wasn't authorized when I used devices -l.
Once it said unauthorized, I was unable to issue the device any commands with ADB, so I just used hardware keys to get into recovery mode. From there, I selected OTA update, and it got into sideload mode. At that point, I used adb sideload with the OTA package that I downloaded here https://developers.google.com/android/ota
^^^ That operation did successfully restore my device to factory
This following guide here describes the details of how to use hard keys to enter recovery on this phone (don't download anything from there tho, and make sure your adblock is on)
How to Hard Reset your new Google Pixel 3a [Tutorial]
In this article, you will learn how to start your Google Pixel 3a up into the Recovery Mode and perform the Hard Reset to make it work perfectly again.
thedroidguy.com
I just wanted to say, I've been wrestling this hardbrick for a couple of days with my Pixel 3a.
I've finally overcome it by sideloading the most recent OTA update after using a hard key combo to get into recovery mode. The hard key combo is hold Power Button, tap Volume Up, then release both. Then, all you need is to use the command:
adb sideload <OTA.zip>
^^^OTA wasn't the actual filename though, you can download OTA packages for Pixel 3A here: https://developers.google.com/android/ota
the OTA binaries are NOT the same as the factory images, which is here
Factory Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
Sideloading the OTA package brought my phone back from only having fastboot and recovery mode, even when flash-all.sh from the official downloaded firmware failed. Now I know how to undo damage that I cause by rooting this thing. Since I sideloaded newest firmware, it was also like applying an update. I easily got root after that, and I've logged the process. I'll make it into a guide soon
I'll just note that if you accidentally flashed the TWRP boot image instead of simply booting into it, I believe all you have to do is flash the stock boot.img to fix the problem. Obviously you can sideload the entire rom image, but that shouldn't be necessary.
Using the Windows computer (or whatever computer you are sending ADB commands from), download the full stock image directly from Google. Unzip it and then upzip the folder inside. You should find the boot.img file inside that folder. Take that file and then flash it to the phone using the normal ADB command: fastboot flash boot boot.img
While I haven't tried this myself recently, it should work in theory. The command "fastboot flash boot twrp.img" flashes the boot partition with a non-working twrp image, so replacing the faulty image with the stock boot.img should fix the problem.
If I did the same I would first attempt to manually put device in bootloader/aka fastboot mode then fastboot flash the stock boot.img , sudo fastboot flash boot boot.img --slot all
I only read the op (first post here);but I betcha that would have worked. Then sudo ./flash-all.sh and let it do it's thing.
