No OS installed. TWRP cannot flash new custom ROM

Hello,
I have a big problem. I don't know what to do.
I wanted to make a clean install of OxygenOS 4.5.8 and so i downloaded it, did it on SD card together with Magisk and no_verity_op5.zip (because i read that this decrypt the data).
So i cleand data and installed no_verity_op5.zip via TWRP, but when i wanted to reboot it takes way to long (i waited 30minutes but it stays on boot circle)
After that i booted into TWRP and decided to made a factory reset and to install OxygonOS 4.5.8 in a clean version. But it was not possible anymore!
When i want to install the .zip it says Patching system image unconditionally... and it loads. after the blue is full it says:
writing static_nvbk image...
patching firmware images...
script succeeded: result was [1.000000]
And when i want to boot into system it says no OS installed.
I tried also to flash this rom or even any other custom rom through ADB Sideload but it does not work. Same like above..
What can i do? I do not know what to do
I hope my phone is not bricked.
Thank you for any suggestion.

Go to oneplus 5 official download page, download stock recovery and latest stock firmware and follow instructions on the download page.... But first with TWRP take a backup of all your data because restoring stock firmware will ERASE everything... Don't panic it will works

First off, don't panic! you're not bricked as long as you can reach your bootloader and recovery.
This happened to me as well and luckily the fix is easy!
You probably tried to flash the OxygenOS build from the Oneplus downloads right?
Somehow these won't flash properly through TWRP and you must therefore also flash the Oxygen recovery image listed in the downloads.
Here are some steps that'll fix your problem.
1 - Backup all of your private data from internal storage because flashing OxygenOS will WIPE/ENCRYPT all data on your device.
2 - Go to the Oneplus download center and download both the latest OxygenOS and it's appropriate recovery:
http://downloads.oneplus.net/oneplus-5/oneplus_5_oxygenos_4.5.8
3 - Boot into your bootloader and flash the stock recovery you just downloaded. (fastboot flash recovery <recovery>.img)
4 - Boot into the Oxygen recovery and flash OxygenOS.
This should get you up and running again.
Once you get tired of OxygenOS simply reboot back into your bootloader and flash TWRP and any rom of your liking.
In the future if you want to flash OxygenOS from TWRP you have to grab a build from XDA I guess. I'm not entirely sure why flashing from within TWRP won't work with stock OOS but I believe it expects to be flashed from withing the stock recovery.
I'm pretty confident this will solve your problems.
Please backup your data first though, don't want anything to get messed up in there!
Good luck!

Ok thank you.
i will try it.
So you are right, i tried to install OxygenOS with TWRP.
So is it not possible to have official OxygenOS with TWRP, Magisk and Root?
So i cannot backup OxygenOS with TWRP?

It is possible to have both OxygenOS and TWRP for sure!
Only a clean flash from a non-encrypted state in TWRP seems to break stuff. You can use a modified OOS build from the forums.
TWRP can indeed backup your OOS install so that shouldn't be a problem.
The only exception seems to be flashing a clean install of OxygenOS (from Oneplus Download center) through TWRP.
Other than that everything works as expected.

Ok thank you.
So i will follow you instructions and i hope it will work.
And i think so.
And after it i will install TWRP again (because i need the backup tool), i will install magisk. will this work?
So i can use everything as in a custom rom, but cannot make a clean install? So official Oneplus OTA will work with TWRP or not?
Thank you soooo much!

Also, Magisk/root works just fine on OxygenOS.
Once you flashed OOS from the stock recovery and have everything set up simply boot into your bootloader and flash TWRP.
From there you flash Magisk and everything should be fine.
OTA's from Oneplus also install fine through TWRP as long as you go into Magisk and uninstall 'root' first. When OxygenOS tells you there's an update simply remove Magisk as I said above and it'll update fine.

Ok thank you!
It worked!!!!! I am very happy!
So i will now install TWRP, and then magisk (newest version).
I have a question, because the last time i installed magisk it did not fully work.
If i install it i have root or? But how can i get saftynet in magisk?

First off! YAY!! glad it worked out!
Be sure to use the TWRP build from the twrp.me website. The one listed on these forums are 'unofficial'. Not saying those are bad, but the official one has a pretty impressive track-record.
After flashing Magisk you are root-enabled so yeah, congrats you are now root! In order to pass safetynet you must enable 'magisk hide' in the magisk manager (the app that should now be installed on your phone).
If you do not have an app called 'magisk manager' then you can download this app from the magisk forums. It should however install itself while flashing the Magisk zip. So assuming you have it installed find the 'magisk hide' service and enable it.
From my experience you sometimes need to reboot in order for it to pass safetynet check.
Glad it all worked out for you!

Everything worked!
Now i have OxygenOS 4.5.8 (with OTAs in future), magisk + root + saftynet and i can install something throug TWRP and backup.
SO PERFEKT.
You are a hero

Can't you just connect your phone to your PC and use MTP for the file transfer? Make sure to have MTP disabled under TWRP-> Mount -> Enable MTP

Well just flash a different twrp via fastboot flash recovery *path to file*

Magisk hell resolved??!!!!!!!??!!!!!!!!!!??

im new at thisxda stuff but i am 90 percent sure i figured out how to keep magisk from uninstalling after a reboot... YOU MAY NEED TO UNINSTALL MAGISK AND ALL MODULES BEFORE DOING THIS USING MAGISK UNINSTALLER basically you have to also install an older version of supersu and it has to be an aroma installer and install as SYSTEM also make a backup of the boot.img just incase you get bricked if you install the supersu app it will say su binary occupied but install should stay install supersu aroma (2.78v2) from https://forum.xda-developers.com/attachment.php?attachmentid=3879523&d=1474248173 before and possibly after magisk install...only tested with magisk 16.2 beta channel and regular install not patched boot on Axon 7 with RR 8.1 weekly 6.0.0 20180225 (us variant) but should work on others probably...let me know how this goes for you
TRY AT OWN RISK I AM NOT RESPONSIBLE FOR DEVICE BOOTLOOPS OR BRICKS
If anyone has a better way to get magisk to hold after a few restarts please let me know
sidenote:this supersu does work with magisk not installed and definately keeps root
(stock boot.img is in initial zip for custom rom) select intall imgs in twrp and flash the boot partition as needed)
ALSO YOU CAN ALWAYS DIRTY FLASH CUSTOM ROM same build or higher IF ALL GOES TO **** AND WONT LOOSE APPS OR DATA AT LEAST ON RR

works for me without problems after last 2 years on any Rom.
dont know what you doing wrong?!

Do I really have to reinstall a stock image? I don't want to lose all my installed data. I've reflashed the phone a billion times getting various things to work, and now that I'm on a stable ROM, I don't want to move over. I've heard this can be an issue with having SuperSU installed. I'm just trying to get certain apps to work, like Fire Emblem Heroes or Animal Crossing Pocket Camp.
I'm welcome to answer any questions anyone has, I just want it fixed.

Why did you flash older version of Magisk? Try flashing Magisk V16 or Magisk Beta V16.3.

Try this method:
1) Flash Oreo RAW
Link: https://forum.xda-developers.com/zenfone-3/development/updated-unlock-relock-bootloader-t3749456 (end of the main post)
2) Boot phone until homescreen
3) Flash TWRP 3.2.1 by @planet9 (make sure you flash the latest version of TWRP)
4) Flash Magisk Beta (v 16.3)
5) Reboot
P.S: Make sure you've backed up all of your important data before flashing

With "Please restore stock boot image" the Magisk installer just want's to tell you to reflash the currently installed ROM: Simply reflash the zip of your ROM (LineageOS), then flash Magisk. No data will be lost by doing that.
The word "stock" is quite misleading here as it doesn't refer to the asus rom.

D802 any root methods are not working!

hi ppl
it was rooted before. used twrp and some custom roms. but later it unrooted somehow.
I tried flashing super su, magisk and ioroot. supersu and magisk turn with an error msg
io root made it stuck on bootloader animation so I flashed a backup.
how to root it?
thx in advance

1) flash latest twrp http://www.gregtwallace.com/lgg2-projects/twrp/ - then reboot into twrp
2) made absolutely all wipes incl internal and data (delete all stuff) - then reboot into twrp
3) connect to usb - and simply copy rom, gapps, and root solution what you want to flash
latest stable magisk for twrp - https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
latest supersu for twrp - Recovery Flashable.zip http://www.supersu.com/download
3) flash the rom what you wanted and flash gapps
3) flash magisk or supersu
(if android 7.1.2 or higher of course - I recommend magisk, because of working nfc pay features, a lot of great systemless addons etc...)
if you prefer old lollipop rom (for example CloudyG2_3.3 ) - it supersu only.
This is the correct sequence - which will eliminate problems with the firmware. If you deleted and installed the root earlier (as you say)

jeezes)) you already killed the rom.... and then restore the all this restores backup, this is a "dirty flash" with a bunch of "remnants". I recommend to do clean flash it in the specified sequence and everything will be ok.
You will spend a couple of 1-2 hours only on installing (and setting) completely all applications. It is not so difficult. But it will save you from a bunch of nonsense questions...
If you actually don't have TWRP recovery installed or old Kit kat Rom - this is absolutely another question and the instructions will not work for you. Also, Kit Kat and Lollipop based ROMs does not support Magisk - because of this error.

thx bro. I did all the steps but it seems same problem going on. sure I want the latest of everything. better updated all. so, using the latest twrp, I wipe all data then format all data then again wipe everything
this aosp rom and gapps worked perfectly. then flashed teh magisk but again its unrooted.
it installs magisk perfectly but root checker says its not rooted. anyway thx for help
btw, aosp rom android 9 has a bluetooth bug. giving a bluetooth stopped message every 10 seconds.

so any advice anout that problem?

you must grant root permission when popup (magisk) appears.
its not automatically
popup similar as in supersu
root works excellent on d802 with Magisk
for example Es File Explorer or any Root Checker

I used supersu and it turned out to be "certification verify" problem. OS not running because of this problem but says rooted. so I can still reach twrp but it really become annoying. this is my old phone and will use as 2nd in my Thailand trip soon.
what to do now? can I use unrooted with a sim card? with no problem?

Please, don't use this nonsense "overquoting" when you answer to someone. Have some respect to the forum rules, and users.
if you want stable rom for LGG2-D802 flash
1) aosp extended based on 7.1.2 or 8.1 versions of Android.
2) flash gapps nano
3) flash magisk zip
4) after rom starts - do the first quick settings - then open Magisk (and if needed update the Magisk manager)
Do not flash both (supersu and magisk) risk to brick the phone.
"device not certified" messege will be always if you use Supersu. It's obviously. Using supersu you unable to use apps like Google pay or any banking apps, because of system root.
Magisk is systemless solution, that's why Google do not recognize Magisk's root. And Play Store on about screen always show "Your device is certified". Also you can Hide root from some apps using Hide option in Magisk manager (it's very useful for local banking apps).
I have a suspicion that you used an older version of Android KitKat (official). And now you try to flash a new Rom (above the Android 7.1.2+). You can't do this. Because you must have Lollipop bootloader. You must be an Android Lillipop first. And then (get Root, then TWRP). And after all that - you will be able to flash some of Rom we are talking about.

Oh Finally!
dowloaded aosp 8.1 and all done. I was trying to use android 9 to be updated. But, pie becoming to be a "creampie" to me so I listened your word. and did it
just opened recovery mode and deleted all the zips. and copied new ones and flashed in order
1) aosp extended 8.1
2) open gapps nano for 8
3) magisk beta (yes this time I tried beta ver and it worked!)
after settings etc. checked with root checker and it was ok. so magisk.apk is not necessary now
thx again bro

Install TWRP via official app after you have root with magisk?

Hello there, back in the day (2019 in March or April the phone shipped with Android 9) I rooted my galaxy S10+ Exynos with Magisk and stock recovery (because TWRP method did not exist yet or did but non twrp method looked safer, I forgot the reason)
Then I forgot about TWRP and even upgraded to Android 10 like this:
(standard procedure, download android with Friya, then patch ap file with magisk, then flash it with odin)
Well I used my phone as always, forgot about twrp, but always had a little voice in my head telling me, that twrp is good idea, what if something happens, I would at least be able to copy my data)
So I decided to flash twrp, to ease my mind a bit, and also be able to copy apps to /system/priv-app
So I am using Android 10 (see no reason to upgrade, what I need is there I prefer OneUI 2.0 over later versions and I dont want to make my device slower or loose some obscure api function that I dont even know exists until I need it)
Now, can I just use official twrp app and let it do its thing (I have root), or do I need to download twrp with the app, but prepatch it with magisk before I install it? (I read conflicting info, on xda they say you need to prepatch it, while on twrp guide: https://twrp.me/samsung/samsunggalaxys10plus.html
They say to just use the app if you already have root, so I am confused now
It seams using the app is the easiest and most safe method
Thanks for Anwsering and Best Regards

only in case recovery and boot share the same partition, you will lose magisk after flashing TWRP (does not apply)

well, I gues this did apply to me, because I tried to flash TWRP with the app (latest version: twrp-3.7.0_9-2 that the app offered, it offered 2 files .img or .img.tar, and I chose to flash .img), and now my phone cannot boot, its stuck in download mode it says with red letters
kernel: Could not do normal boot, (DT LOAD failed)
I don't know know what happened, I only flashed recovery, and bootloader is unlocked
adb doesn't work
I cannot even get to recovery
So what now? Can at least flash TWRP somehow back so I can get ot my files (I have most of my videos on an SD card, but 2 or 3 are on internal storage )
I would reflash Android 10 anyway if it wasn't for the files

you can flash recovery.img as tar file but that is useless for backup stock ROM userdata. if you still have the magisk_patched.tar you can flash it to get your data back. don't flash unpatched stock boot.img this will most likely result in data loss.
I would first try older TWRP as DT LOAD failed (device tree) looks like TWRP problem to me.

OK
after installing TWRMP
3.4.0 I got into recovery​
I guess the latest version twrp-3.7.0_9-2 is broken (because I tried flashing from Odin and I got the same error
but 3.4.0 works now
Well then I got into a non rooted android state (I couldnt boot into the rooted one because if I held volume up I just got into TWRMP)
I do have my magisk patched AP file (I did keep that), so I tried flashing it by odin to get into rooted state again, but then got scared because I was aftaid it would delete my data, so pulled the plug out, immediately after I discovered its flashing system.img (it just started)
thats where I interupted it
<ID:0/035> SingleDownload.
<ID:0/035> dt.img
<ID:0/035> dtbo.img
<ID:0/035> system.img
<ID:0/035> __XmitData_Write
<ID:0/035> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
So then phone would not boot, not in TWRMP not in android anymore, so I flashed TWRMP again and now at least
I am in TWRMP (I can see my files, but they are encrypted (they have wierd names but size does seam to match my files)
So how do I reflash android now, without messing with /data partition?
or can I somehow backup just data partition, reflash android and flash /data back?

let the magisk_patched.tar flash, just make sure you don't flash CSC (HOME_CSC is fine it won't erase userdata)

Yey, that did it (that was scarry), now root works, as well as android 10 (for some reason Magisk Manager does not open (but all the magisk modules work)
Now, I did patch this ap file back in the day I updated android to 10 so
I used Magisk Manager 7.4.1.291c718b
and if I remember corecly (thanks got I recorded everything) I patched the AP file for Magisk 20.2-11b7076a)
Now I have Magisk Manager 8.0.7 installed
So after I downgraded my Magisk manager to 7.5.0 it opened
Now I just have to figure out how to install Magisk v21.4 which is the version that belongs to my Magisk Manager 8.0.7, because Magisk Manager won't let me install a custom magisk, it only wants to download the latest version

you can install latest Magisk apk and patch stock boot.img again. Anyway I would do a backup with Migrate and adb pull -a /sdcard first.
or you can paste this url as custom channel and install older magisk if you want to.

aha, I see
is there any other way besides patching my AP file again? (I mean Magisk can clearly update itself somehow)
I mean, Magisk Manager does open (but only version 7.5.0, not version 8.0.7), and I have root its just that I don't have Magisk Manager 8.0.7
So how do I install a specific Magisk version from Manager? (I did try to install like a Magisk module, but now I am stuck in download mode again, so lets install Android 10 again )

look in the json for download link
https://github.com/topjohnwu/Magisk/releases/download/manager-v8.0.7/MagiskManager-v8.0.7.apk

OK, after I installed Android again (with my older prepatched magisk)
Not sure what happened but now Magisk Manager 8.0.7 opens and says I have 20.2-11b7076a installed
of course as this combo should not exist, magisk Manager cannot see any modules (modules are there in /data/adb/modules and they do work, its just that Magisk Manager cannot see them installed, which means you can not easly delete them and you could install them over and over again, since Manager would not know that they are there)
So now I need to find a way to update to Magisk 21.4
So how would I do that (I tried the module install method before (I downloaded 21.4 from official github release pages) , but that just got me stuck into download mode again, so any other way, is there a patcher for computer maybe?
I mean I can only install the latest version, even if I disable internet, I cannot select a specific version

refer to post #8

Thanks, after spending 3hours to get into magisk I decided to share my procedure (because I forget it a lot)
FIrst: make sure your phones last state was power off (you can eather power off from red button or from recovery)
Then turn phone on and start holding power button + bixby + volume up, and count to 10 then release (not 11, 10, if you count to 11 you will get to recovery)
To try out if you are in magisk mode (without ruining your saved wifi passwords), you can plug the phone into the charger, if it turn on normaly, you are in magisk, if it shows battery charging, then you are not in magisk mode)
OK, I tried updating Magisk with https://raw.githubusercontent.com/topjohnwu/magisk_files/b0694fad86/stable.json
but for some wierd reason, it doesn't want to update, its stuck on 20.2-1
OK,. I tried installing Magisk Manager v7.4.1 and when launching it, it said that it patched dtbo.img and it needs reboot, so after I reboot, I am stuck on download mode again
It sayd: DT table header check fail
well, lets install Android 10 a third time

wait, you're booting into recovery to get into Magisk? you can use Nemesis kernel to skip this.

Yes I am, but its allright, I am used to this
one day I will have to compile my own kernel anyway (to add some drivers to the phone)
Now I have to figure out why Magisk 21.4 won't install
I tried patching my AP file with it, but no matter what I do, I cannot get into it for some reason? (even my trust and tried method does not get me into it, while it got me into 20 all the time)
Is this version broken?
Whats the latest magisk version that still supports Magisk Hide (usefull thing that always worked for me)

With Nemesis kernel no need for button dance, it boots straight into Magisk. Magisk Hide exist up to v23 but there is also unofficial Magisk v25

only in case recovery and boot share the same partition, you will lose magisk after flashing TWRP (does not apply)

Magisk needs the ramdisk of the recovery/TWRP to patch it. If flashing a non-prepatched image you will lose root.

Yea, I discovered that already
Now I am trying to get it back and failing
UPDATE: after installing Magisk 23 (last version that has Magisk Hide), prepatching AP file, and flashing it like 10th time, I finaly have root
Do I dare to try TWRP again? (I guess I need to prepatch it with Magisk before I install it with odin? (but which file do I install there are 2 files provided (twrp-3.4.0-2-beyond2lte.img.tar or twrp-3.4.0-2-beyond2lte.img)?

patch the tar file
