Having problem rooting my Axon 7 A2017U

Hey guys, first of all sorry about my english, im french.
So my problem is: I tried rooting my Axon 7 A2017U many times, with different guides. I always end up with a softbricked phone, having to restore to stock using MiFlash.
My bootloader is unlocked, i have stock recovery and stock rom for now.
Whenever i flash TWRP, either the signed one (from @tenfar) or unsigned (and up to date) ones, i can't go past the menu saying something like "your phone cant be checked for corruption, please lock your phone [...]" it just freeze. i did read somewhere that i should flash chainfire's root or a special .zip that, i guess, disabled some check that could prevent booting a phone with unsigned stuff/edited system (after flashing TWRP, so it could boot) that didn't work out. i think i found that information in some LineageOS thread here on XDA.
My ultimate goal would be to get a rooted stock nougat 7.1.1, up to date TWRP recovery and to be able to switch to LineageOS to try it out soon.
For what it is worth, i rooted many phones over the years, so while i'm no expert, i should be able to follow most of the steps you give me.
Thanks alot!

What version of TWRP did you flash first?

Okay. Download and flash this one alone via fastboot and see what happens. This is one the I personally use. It is required for any of the newer versions to work properly.
twrp-3.0.2-2-a2017u.img
You can choose to rename it to just recovery.img, then:
1. fastboot flash recovery recovery.img
or
2.
if you choose to work with the same filename:
fastboot flash recovery twrp-3.0.2-2-a2017u.img
Select reboot to recovery from the bootloader menu now and try again.
Either way, should work fine. I know you mentioned you knew the basics, but just want to be sure.
Also forgot to mention. If TWRP works but you still can't get your phone to boot, you need to follow this guide here
You can start from the part that says:
-----------------------------------------------------
UPDATING FROM B20_Boot / B20 / B27 / B29 / B15(N)
-----------------------------------------------------
Again, that's the ROM I personally use if I want to go back to stock, not the one from the ZTE site.

Gonna try it and give feedback. thanks for taking time to help!
edit: im downloading the rom from the link you shared.
like you said, i can get TWRP to boot but not the phone.
So if i use full stock from ZTE, it can't boot with modified recovery?
edit 2: i don't know what worked, i think it might be the bootstack. or the rom by DrakenFX. now i can boot to the rom with a TWRP recovery installed. It worked, but i soft bricked again trying to flash SuperSU. So now i'm retrying with an updated TWRP.

I haven't tried that yet, but I really suspect that's the reason you're having problems. I rarely use pure stock ROMs. Like you, I'm not an expert in Android Development so I can't tell you why. Just been a flashaholic for years so made a few observations.

Which supersu are you installing? If you're swiping to the right in twrp, you need to install the dm-verity zip or supersu 2.79. There's some issues with newer builds.

Everything is working like a charm! Now im going to finally give lineageOS a try
I used Chainfire's SuperSU 2.79 stable.
Edit : Everything is working flawlessly! I'm running the lastest LineageOS nightly with root (Chainfire's 2.79). Followed their instruction and installation was smooth as butter. I should also point out i flashed the lastest official TWRP which seems more stable than the one @KwesiJnr suggested. The one he suggested was giving me some "can't read X partition" in red text everywhere in the log section, which the official one doesn't do. It was doing his job properly anyway though.
I can't thank @KwesiJnr enough, it helped me find the single mistake i was making.

Yeah, like I mentioned before that was the base TWRP you needed to flash first, before any of the newer ones. You weren't intended to use it indefinitely.
There's a lot of Dev love for our device now and support is growing ... exciting new ROMs cropping up. Don't hesitate to try them out.

Accidentally flashed boot to TWRP

Good evening!
Well, my problem is, that trying to install TWRP as recovery (which I did). After doing it, I used the following command -stupidly because I wasn't thinking- thinking it was another thing:
flashboot flash boot twrp.img
Now, everytime I try to boot my OP5, it loads the TWRP.
Now, what can I do? I have the full 4.5.12 OTA that I downloaded from a post in the original OP5 forum, but the one I have installed in my phone is the 4.5.10 or 4.5.11 (I'm not sure now, the last one available before the .12).
Thank you very much!

1.Unzip the full OTA file
2. Take boot.img from OTA file
3. Execute following command:
flashboot flash boot boot.img

Thank you very much!
But what if my version is not the same as the OTA I have? Will that affect? Because my version is for sure lower than what I have.

You can flash the OTA (if it's over 1GB) in TWRP too.
That will simply update your software to the latest version and will hopefully also bring your phone to a working state.

In other words, what you did was flash TWRP to the boot partition instead of the normal recovery partition. Simply reflash the boot.img to the boot partition and you should be good to go. The boot.img is mostly the kernel and doesn't usually change much from OTA to OTA so you should be fine.

Help with soft brick

Hi guys,
I got the ASUS Zenfone 3 Zoom and started playing with it. Unfortunately I managed to soft brick it and somehow I can't go back to stock. Here are all the things I did. I would be happy to get any ideas what to try next:
1. unlocked the bootloader - using asus's official unlock tool
2. flashed twrp recovery - twrp-3.2.1-0-Z01H-20180304.img, using:
adb reboot bootloader
fastboot flash recovery twrp.img
3. updated asus's firmware to the latest official one:
copying UL-Z01H-WW-71.60.139.30.zip onto internal memory
android detects the update and applying it using android
4. Enabling lock pattern at boot (from android settings). Correct pattern required even when booting into recovery
5. Installing supersu via twrp:
adb reboot recovery
installing supersu
wiping caches (the cache partition cannot be wiped)
6. SuperSu working (tested via android)
7. Reading about Magisk. Trying to install magisk via twrp. Magisk's installer complained that the system is not vanilla (due to SuperSu modifications). Have to uninstall SuperSu to return to previous state.
8. Tried uninstalling SuperSu from the program itself (in android). The uninstaller got stuck. The phone become unresponsive and had to reboot.
9. Found a script packaged as an executable zip (to be installed via twrp) that will uninstall SuperSu and return system to pristine state (SuperSu makes a backup of the files it changes before installation) - UPDATE-unSU-signed.zip. Uninstallation worked.
10. Magisk installation still complained about the bootloader. Then things started to go wrong. I unpacked the latest firware UL-Z01H-WW-71.60.139.30.zip, took out boot.img and tried to flash just the bootloader
fastboot flash boot boot.img
11. Upon reboot the phone got stuck at the ASUS logo. Reboot into recovery and into fastboot still works (soft brick). Still shows unlock pattern at boot.
12. I tried flashing the original firmware using TWRP (install a zip). However the installation threw some errors. Unsuccessful.
13. I've tried flashing the system.img from the original firware using fastboot but still it's stuck at the ASUS logo at boot.
fastboot flash system system.img
Here I am stuck. I've read that TWRP cannot install properly the ASUS official firmware but if you flash the original recovery, it can probably flash it properly. Another thing that I think might explain why I cannot get out of the soft brick is that I've enabled the lock pattern at boot, which effectively encrypted some parts of the phone and I have a strong feeling this interferes with the boot process. I will look for a script/installable zip (via twrp) that can remove the lock.
I really need ideas/suggestions before I make something that will turn my phone into a hard brick. Thanks.

What you need to do is flash stock MM recovery from bootloader using "fastboot flash recovery recovery.img"
Since it came with MM preloaded you'll have to install the ROM using stock recovery via adb. It'll take a while, but after that you should upgrade to the latest MM update.
After that, update to any Nougat patch update you wish to receive, because I still haven't figured out yet how to apply them all with @shakalaca's recovery images.
Once you're done, you can install twrp again and flash magisk.
Good luck and hope this helped you

Thanks

Thanks,
I tried to find a stock recovery images but unsuccessful. Can you tell me where to get it from?

Here's a link to Shakalaca's recovery images.
In the Old folder you'll find MM stock recoveries.
https://mega.nz/#F!p90wgAaY!l1JbJilmAUEKTKWu43pT9w!I89QgZpK
Flash 11.40.86.75 recovery
Boot into recovery
Flash 11.40.86.75 stock rom via adb (it'll take a while)
Once it's done, boot into Android.
Download your respective region's latest MM rom.
Send it to your micro sd.
Install it once Android detects the update file.
(It won't work with custom recovery. I tried every recovery Shakalaca has and only those two seem to work)
Once on the latest MM rom install any nougat patch update you wish to apply, because once you have a nougat rom, you can't boot stock recovery. (As far as my testings went)
So if I were you, I'd go for any update after the zenui 4.0 update since it's a bit better looking imo.
After that final update you can flash TWRP to root your phone. I prefer using magisk, since it doesn't modify the system files.
All you need to do is flash magisk and that's it. No need for SuperSU or anything else. And by any means, do NOT wipe your cache partition once you flash TWRP, otherwise you'll get stuck on the Asus logo during boot.
If you wish to retain the "certified" status in google play store's device certification, do NOT go into the play store before installing magisk. Also, don't delete play store data, otherwise you'll lose your previous purchases.
This post was longer than I initially thought it'd be, but I guess this sums it up pretty well.
Good luck

Thanks, I managed to flash 11.40.86.75 and stock ROM using your instructions. I will look now into updating and applying magisk. Just a final question. You mentioned to install Nougat patch update and not a full firmware, but my phone came preloaded with Nougat. Will this be a problem? I installed stock 71.60.139.30 and it worked fine (i was able to boot into twrp).

Hi I managed to flash stock ROM - 71.60.139.30, but after that I can't flash twrp - twrp-3.2.1-0-Z01H-20180304.img. I tried with:
adb reboot bootloader
fastboot flash recovery twrp.img
but when I try to boot into recovery with:
adb reboot recovery
it goes into the stock recovery. Is there something I missed? Do I need to downgrade to flash TWRP?

Quick question: which of these warnings do you get when you boot?
https://www.androidauthority.com/go...rrupted-and-modified-android-software-629180/
Also, did you try power cycling to get it to boot?
And since the version number made such a large jump, I believe they must have changed something internally with the latest update and that it's probably going to be one of the last Nougat updates before Oreo (which was delayed until June).
I still need to update to that version to check it out, but I might reset soon since I was waiting for Oreo to reset.

I have the Orange warning. It looks a bit different but the wording is the same. Yes, i tried powercycling and still I boot into the stock recovery. What can I do now? Is it possible to downgrade? I am not sure if I boot into stock recovery if it will let me flash an older stock ROM.

Hi, I managed to get around it by directly booting into TWRP from fastboot. Yes, apparently unless I flash some TWRP files to the system partition upon next reboot, the recovery will return to stock. Anyway, I managed to install Magisk and Exposed framework and have been poking with those two for the last couple of days.
The youtube vanced app is great, but I found something that worries me. I can't login to facebook/twitter. I checked and the reason is I can't connect to the facebook.com or twitter.com https sites (even over chrome). I think either:
- I've installed some module which is messing with that
- my rooted phone is hacked
I've installed a module that is meant as ad blocker, that updates the hosts file. However I removed all modules and the problem remains. I really don't wanna start all over again just to check. And even if I reflash and it works, I will not know what caused it and how to fix it myself next time. Do you have any ideas on how to figure out what the problem is?
Regards,

First off, my apologies for this late reply (Been superbusy with school and internship assignments)
Secondly, and that is why I only use magisk. Because once you mess with the host file, depending on what module you install, it can range from tripping safetynet to bootlooping.
So quick question, is it still in this state right now since 9 days ago?

it seems youre trying to flash a new twrp image that is higher than the allowed 3.2.3-4 in the root process,go to fastboot mode reflash twrp image 3.2.3-4 or an older one.If that's not the issue please provide more information

Where does it exactly say that I cannot flash anything higher than 3.2.3-4. All it says is to download the latest twrp from https://forum.xda-developers.com/v20/development/recovery-twrp-3-2-1-0-t3720239
Do you have a link to 3.2.3-4? It seems like 3.2.3-5 is the lowest twrp I could find in Phoenix591's android filehost https://androidfilehost.com/?w=files&flid=235271
edit: while waiting for responses, I went ahead and installed unofficial LOS15 then I was able to boot without any problem. It seem like this will only happen with stock/stock based roms.

You should flash latest after installing this one by installing recovery img in TWRP i am telling you cause i have tried 3.2.3-5+ with the dirty santa process for my phone and thats the message i was getting unless downgrading to 3.2.3-4
Also decryption is unsuccessful comes as a result of not formatting data on twrp after the first install of twrp but you said that you did format data so i thought you were trying to flash newer twrp via the root process of the H918

I am never new to this problem and usually this get solved by going to twrp and wiping data(the one you have to type yes) but it did not solve this problem. Really need help badly.

I have this problem too for a couple days a go,
but now it have been fixed.
Flash TWRP 3.2.3 via fastboot
Boot into TWRP
format data
reboot system
done
I think Its TWRP 3.3 bug or something that not decrypt perfectly..

do you have 3.2.3-4? I couldn't find it anywhere unfortunately
edit:already solved it by using 3.2.3-0/1 from official twrp website. but the problem is that i get 0mb storage on internal storage on TWRP. I am not exactly new to this problem but even after flashing no verity op encryption zip. I still get it. sigh.

I did format data so many times already that it nuked my twrp(just stopped booting into it all of a sudden, still unsure if that caused it though)

Yes me too, and it almost make me crazy back in the days ?
the solution (at least for now) is downgrade TWRP it into v3.2.3-4. flash it via adb fastboot command, format data, then reboot. But sorry i dont have TWRP for H918, becoz im using F800L.. and since your TWRP has been nuked, youll have to reflash TWRP again yes? ?
Or, if youbdont want to downgrade TWRP, you can use AOSP based rom such as LOS15.1.. i already tried that rom and it dont have problem with encrypt/decrypt thing like stock based rom.

Thank you so much, no wonder i wasn't able to find v3.2.3-4 because it's labeled as the release date. What does the sim unlock do? I mean, I can receive messages and stuff but just not get any once in awhile. Will this actually solve that?

Yes i knew that. My TWRP 3.2.3-4 IMG file is labeled with same date like that.
About sim unlock, Actually I dont know for sure because in f800l we dont seeing any sim problem at all.. but in my opinion just download it, in case you seeing problem with locked sim after flashing, it will be very useful..
anyway, i found a thread that discussing about h918 sim unlock thing

Thanks, I will try going back to stock roms and will report back to you.
And I forgot to mention that I already got twrp fixed after it got nuked. Sadly, I don't think fastboot flashing works on h918 so I had to do lafsploit method to flash twrp again.

Where does it exactly say that I cannot flash anything higher than 3.2.3-4. All it says is to download the latest twrp from https://forum.xda-developers.com/v20/development/recovery-twrp-3-2-1-0-t3720239
Do you have a link to 3.2.3-4? It seems like 3.2.3-5 is the lowest twrp I could find in Phoenix591's android filehost https://androidfilehost.com/?w=files&flid=235271
edit: while waiting for responses, I went ahead and installed unofficial LOS15 then I was able to boot without any problem. It seem like this will only happen with stock/stock based roms.

Where? Right in the portion where it says Known Issues of the first link.
Downgrading TWRP to 3.2.3-4 will fix it. I had the same issue.

Thanks for the notes. Unfortunately this did not work for me. I ended up in this position after updating Magisk to 20.2, or trying to. My H918 went to being stuck in the fastboot mode. I was able to get to TWRP, and reinstalled H91820h.zip, but then faced with "Decryption unsuccessful" I downgraded TWRP to twrp-3.2.3-0, and deleted everything except the external microsd card, reinstalled H91820h.zip, but still stuck at the "Decryption unsuccessful". Are there other things I should try?
Thanks,
Rob

From TWRP thread:
Changed one last thing to try to fix stock Oreo decryption.
There were an upstream TWRP change that should fix the issue where formatting was still leaving /data encrypted as well (this was actually in the last build, but I didn't notice it then)

If you still have your non-Encryption-supporting TWRP as download mode, wipe data from there. For some reason which was documented in the TWRP thread, most versions of V20 TWRP doesn't remove the encryption flag even on a full wipe. I've gone through the pain several times, but here's roughly what I went through about a month ago. It's possible that using the latest TWRP may allow you to skip straight to step 8. As of this latest wipe, I'm finally at a point again where my phone works properly and TWRP can still see my data.
Basic process to hopefully have a working ongoing phone and TWRP:
1. Reboot to download-mode TWRP
2. Wipe dalvik/cache/data from the older download-mode TWRP
3. Factory reset with YES, still in older download-mode TWRP
4. Reboot to system; it should give you the new-system-setup past the Decryption unsuccessful screen on your wiped device
5. Setup without a Google account or fingerprint
6. Reboot back to recovery, not download TWRP; use download mode to get there if you need to
7. Flash the latest TWRP version from the thread (no older than October 25, 2019)
8. Reboot back to recovery
9. Wipe dalvik/cache/data
10. Reboot back to system
11. Setup as you like
12. Reboot back to recovery and make sure you can see your storage
If it gets a decryption error on latest TWRP at step 12 and you can't see data while in Recovery, try skipping adding a fingerprint during setup (run through steps 8-12, no fingerprint on 11) and see if that fixes it.

My solution turned out to be formatting /data. Wiping it was apparently not really wiping it clean. Formatting it got me back to a working phone, though I had to re-install everything.
Thanks everyone for the help!

anyone knows how to fix fingerprints not working? h990 oreo rom mk2000 kernel is there any fix?
do i need to return to nougat but than what? please help
edit: was able to fix that by flashing nougat modem
now wifi wont turn on tho anyone know how to fix?

I keep loosing root after reboot, Pls help.

Hey guys,
first time posting here so i dont kow how to style the text, so sorry about that.
last time i rooted a phone was on my sony xperia sp , where all i had to do was to go to towelroot .com and click to root.
I tryed to root my OP6T yesterday, after some setbacks i managed to sucessfully do it.
I did it like this:
1. Downloaded full ROM of OOS 10.3.2,
2. copied the payload to a program called payload dumper that extracted the boot image.
3. Copied the boot image to the phone
4. opened Magisk manager and selected install from source where i chose the boot.img
5. it created a copy called magisk_patched.img
6. booted in fastboot
7. on my pc used the command prompt to "fastboot boot magisk_patched.img"
booted normally and i had root.
but then problem appeared
#Problem 1
everytime i rebooted my phone i would loose root and it would say Magisk not installed. To get it back i would need to perform step 7 again and it was not ideal to do that everytime i turned off my phone.
#Problem 2
While tryng to solve problem 1 i read that i needed to open magisk manager and "Install to Inactive Slot (After OTA)."
After doing that it rebooted but now it wont boot at all, even if i try to "fastboot boot magisk_patched.img" the cmd gives me error:
fastboot boot magisk_patched.img
downloading 'boot.img'...
OKAY [ 0.838s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.845s
now my phone is just sitting there i dont want to reset it again. it would be the 4th time that i need to set up my phone in 2 days, so im trying to see if there are alternatives.
If reset is really the only way, i read that with root you can make a full backup of your phone and then restore it. How to do that? can i do it in the situation im in?
How can i root my OP6T running OOS10.3.2, and keep it? Whats the right method bc the one i followed seemed flawed.
I also tried one that had TWRP but maybe i did something wrong bc it didnt work., also there is no official one working for 10.3.2.

What is happening is normal with those instructions (they aren't right).
All you need to do is install TWRP. Do not use the official one, it is out of date. Use TWRP from this thread Link here. The TWRP from that thread is from the official maintainer. It works fine with OOS 10.
- You need to get the phone in fully working order again. Which may mean you need to use the fastboot ROM, as you've probably "goofed" something up at this point. (no offense meant). Make sure your phone boots and such after this.
- For OOS 10 with the phone in fastboot, fastboot boot recoveryimgfilename.img (<-- For OOS 10 you will need TWRP 3.3.1-32 Q Unofficial by mauronofrio from the thread I linked to above) This will boot to TWRP.
- Now run TWRP 3.3.1-32 Unofficial Installer by mauronofrio this will install TWRP. The installer is the same for Android 9 and 10, doesn't matter.
- Once the installer runs, click back, choose reboot to recovery. If you boot to the system, you have to start over. Reboot to recovery!
- Install Magisk 20.3 <-- The current version. The official download page. After that you can reboot to the system. You should now have a rooted, phone with Magisk, and TWRP installed.
Any questions ask.

So getting it straight, i need to first reset my phone and then do the steps you described.
Can i backup the data first with TWRP to restore it later and avoid setting up everything again?

Supposedly. I've never used that function of TWRP. Some people have luck with, some people restore things that shouldn't be restored and end up having to wipe the phone again. Personally I just use TitaniumBackup like I always have. I would search for information on that in the TWRP thread if you want to try method. I don't know enough on that to provide solid information.

Hey man,
Thank you so much. It worked and i stay rooted even after reboot.
May i ask how you use the Titanium Backup, i think back in the days all i used it for was uninstalling system apps. Or if you know some nice guides. If you know other good things to checkout now that i have root i would appreciate it, i have been far away from rooting for too long.
Once again thank you so much

I use it to back up app and app data primarily. It allows me to restore data to apps after a clean install. Since I have the Pro version it's just a batch action (one click essentially). There is also a way to create a flashable .zip you can use in TWRP, although I haven't tried that method, as I'm typically not restoring apps, just data. I also use it remove apps from time to time.

Hey man, im sorry i am once again in need.
Idk why but at first i can reboot the system normally without issues. but after a while once i set up everything it just doesnt boot anymore. Am i missing something? do i have to do anything with magisk? download a module or something?
Could it be that google security update is the fault?

When you installed everything originally did you fix everything with a clean install? Both slots are the same version of Android? (Like you don't have something weird going on like Android 9 on one and Android 10 on another?)
You definitely have something abnormal going on. There shouldn't be anything in Magisk that you have to do, at least not to prevent crashing. I normally hide it, but that has to do with keeping apps from detecting root.

I got it to boot by uninstalling magisk,
I am 100% sure i dont have two different version of android in different slots, bc yesterday i was in big trouble and nothing was working and i flashed on both slots the same version of android 10(dont remember exactly wich one as i tried a couple, but they were the same).
Today when i couldnt boot anymore i went into stock recovery, factory reset -> when it booted i placed the stockOS.zip file in the phone and applied update from local file -> after that i factory reset again from the system settings, so i think the phone should have installed it properly.
Only after that i did what you told me and installed TWRP and Magisk. and as i said it worked and i could restart my device etc..
After a while when i restarted i couldnt boot anymore and went to bootloader. Removing Magisk fixed it,apperantly on install magisk creates a copy of the boot.img that it restores on uninstall, and i booted to system.
Now i can use my phone but dont have root.
Im very thankful for you being there and helping me out trough this, i cant thank you enough

Not sure if you're still having this issue but I'll post the solution just in case anyone gets stumped, does a google search, and comes across this post. You were using the wrong command.
"fastboot boot" just lets you boot with the img so you can verify that root works.
"fastboot FLASH boot" will flash it and root will stick after reboot.
No need to jump through hoops with TWRP and such.
