[GUIDE][OREO 8.1] How to recover from soft bricks [UNLOCKED BOOTLOADER] - Honor 9 Guides, News, & Discussion

DISCLAIMER
This guide requires your bootloader to be unlocked. If it isn't, you'll most probably need DC Phoenix.
This guide applies to Android 8.1 roms because the TWRP for it doesn't support decryption which makes recovering harder and made me want to create a guide.
GUIDE
When can this guide be applied:
- You installed an Xposed module that caused a soft brick.
- You uninstalled Magisk while Xposed still being active.
- You flashed an Xposed version that caused the soft brick.
- You flashed an oreo system.img that won't boot.
- Any other issue caused in the system partition that gets overwritten by a system.img flash.
1. Reboot to Bootloader
2. Re-flash your whole system.img
3. Reboot to stock recovery
4. Format cache
5. Reboot
You won't lose your data.
If you installed a substratum theme causing a soft brick, you can apply this guide but unluckily you will have to factory reset as well.

Any way to recover files from D6616 bootlooped by SuperSU bug?

Is there any way I can grab files? I have very important data on this phone and wasn't expecting it to brick itself without warning.
I can get into flash mode and fastboot. Fastboot mode does report the phone.
It was bricked upon reboot by the recent SuperSU bug.
I cannot get into CWM/TWRP anymore, so I don't have ADB.
I have reflashed same ROM using Flashtool without wiping USERDATA. Installed newest cracked SuperSU 2.82 and disabled automatic update.

Stuck on bootloop TWRP without decryption, help.

Hey guys, so i had weird problem (status bar not visible after unlocking device) when updating my phone to 9.5.8. so i decided to flash the rom again to see if the issue goes away. I am rooted and unlocked and everything was working fine (apart from the status bar). I tried this method:
1. Downloaded the 9.5.8 update from Oxygen Updater (DONT REBOOT)
2. Went to Settings\System\System Update and click on the wheel on upper right corner.
3. Select Local Upgrade, then install the update (DONT REBOOT)
*DO NOT REBOOT after applying the update.
4. Launch Magisk, and click the first "install"
5. Choose the "Install to inactive slot (OTA)" option
6. Reboot once completed
On step 6 it failed, i rebooted directly into the Oneplus recovery and not TWRP. So i tried fastboot boot twrp.img and flash the installer. After that i rebooted the device and now it goes directly into twrp but without decryption, it wont ask for my PIN and i get the screen "Unmodified System Partition. Keep System Read only? Installing zips or performing adb operations may still modify the system partition." On the bottom i can "swipe to allow modifications", which i swipe to allow but i can't access any files on my phone, and that is my dead end. Help would be much appreciated.
I also tried flashing Magisk and also Magisk Uninstaller (uninmod wasn't found).
Also tried command "twrp decrypt password" in the Terminal and got "Failed to decrypt data"

So to be clear: right now, you have access to twrp but not the data partition (twrp does not prompt you to decrypt), and when you reboot to system from, you are bounced back to twrp. Right?

Yes, but i got frustrated and as i had done a Titanium Backup i just wiped everything on stock recovery and flashed the latest rom with twrp. Is there a clear instruction on how to update the rom when rooted? I just don't want it to happen again.

Don't mess with stock recovery if you already have TWRP and Magisk aboard.
Here's how to update to 9.5.9 (or whatever) when it arrives:
- download your 3 zips: the latest full ota ROM, the latest Magisk, and the latest TWRP installer.
- boot to TWRP recovery
flash the ROM and TWRP installer
- reboot to TWRP recovery
flash Magisk
wipe dalvik
- reboot to system
There's a possibility after these steps and you're happily on the ROM, you might find that you're not rooted (it's more likely on a custom ROM than OOS). In which case you just reboot to recovery and flash Magisk, and then reboot to system. Done.
Discussion:
If you want a clean flash, you'd simply do a TWRP factory reset (standard wipe) instead of wiping dalvik.
Consider flashing both slots (A and B) whenever you update OOS, for two reasons. First, you don't have to keep track of which slot has which version of OOS should you flash a custom ROM or kernel with a specific version of OOS required as a base. The second reason is more compelling: the way the data partition changes encryption every update has obviated the reason for A/B slots, in that if newly updated B changes data encryption upon boot and then something happens, you cannot revert to A because A can't read the new data encryption. So the solution is to update both A and B at the same time so both slots use the same encryption and can both access the data partition.
Or like me, run the device decrypted (i. e. without forced encryption).
Good luck

[SOLVED] Installing ANY custom ROM bricks Oneplus 6

Hello!
I'm having quite a hard time figuring out what is happening on my new Oneplus 6.
The first time i flashed LineageOS 16 microg edition it booted but since i tried to restore stock ROM backup with TWRP it all went to hell.
Device immediately bricked, only booting to fastboot.
Had to use msm tool to unbrick. ( the first of so many times.... )
Then updated from settings to latest OOS 9.0.9.
unnlocked bootloader
and flashed again.
NO OS INSTALLED.
phone boots only in fastboot.
can't boot any recovery from fastboot. gives error.
if reboot to recovery blue led and black screen is all that i see.
only fix is msm.
From that point onwards i tried EVERY guide I could find (and recognize as valid of interest) here on xda, youtube, google.
Multiple times per guide.
here's an example of a "last resort" guide from https://forum.xda-developers.com/oneplus-6/how-to/guide-microg-oneplus-6-source-ligthway-t3874469
INSTALLATION TUTORIAL
Italic = recommended, but not mandatory. Do it if something doesn't work properly
0) DON'T RESTORE your apps until everything is set up, otherwise you'll have issues with GCM (getting instant notifications from messaging apps for example)
1) Reboot to blu spark TWRP
2) step deleted
3) Flash OOS
4) Flash TWRP
5) Reboot to recovery
6) Flash OOS
7) Flash TWRP
8) Reboot to recovery
9) Flash your custom ROM + TWRP + reboot to TWRP
10) Flash again your custom ROM + TWRP
11) Reboot to recovery
11 bis) Wipe data ("factory reset")
12) Flash Magisk
13) Reboot to system. It's just to make sure the installation worked.

Tried also official lineage, SyberiaOS. Different previous version of the two (since I read in the lineage official thread others have this issue)
Basically at the point after flashing any of these roms results immediately in TWRP warning "no os is installed" at reboot attempt with or without re-flashing twrp after.
Then if rebooted just hangs on blue led. can't boot anything.
Meanwhile flashing OTAs + twrp results in bootable system.
Other things that i tried:
before unlocking BL update to latest OTA_34 -> 9.0.9, reboot, install again.
using mauronofrio twrp version https://forum.xda-developers.com/on...overy-unofficial-twrp-touch-recovery-t3860815
Any ideas?
[SOLUTION]
If you're bricked follow this: https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892
1 - Have last OOS installed in both slots
- update from settings, local update, latest OTA (Pie) from oneplus support site.​- reboot, let it complete​- apply again​2 - Enable OEM Unlock in Developer options
3 - Boot to Fastboot and unlock bootloader:
Code:
fastboot oem unlock
4 - Once in OOS reboot to fastboot and boot twrp:
Code:
fastboot boot <twrp-img-name>.img
5 - Push twrp + custom rom:
Code:
adb push <custom-rom-name>.zip <twrp-zip-name>.zip /sdcard
6 - Flash twrp in twrp
7 - Reboot to recovery
8 - Wipe system and Data
9 - flash ROM
10 - flash twrp
[IMPORTANT]
11 - Tap Reboot to recovery then if it says No OS installed! tap home button! Don't reboot! reboot = brick = msmdownloadtool
12 - Go in advanced menu and select Fix Recovery Bootloop and swipe
13 - THEN TRY TO MOUNT /system.
IF YOU'RE UNABLE TO MOUNT /system APPLY AGAIN THE FIX AND REPEAT FROM STEP 7​14 - Reboot to recovery
It WILL stil say No OS installed but now you'll be able to reboot to recovery​[/IMPORTANT]
15 - Once in recovery reboot to system.
If you've done everything correctly it won't complain again about no OS being installed and you'll get your rom up and running.​16 - Let it reboot to system and complete first configuration
17 - Now you can reboot and flash every module you like from twrp.
That's it. Hope this'll spare nightmares and storage write life.
This is a bad phone .. I have it too

But you seem (from post history) to be able to install ROMs :crying:
As most of those who try i guess.
Maybe my phone is somehow damaged
What some guides miss out is that you have to install everything twice. Once on slot A and once on slot B and after each install, verify what slot you are on before reboot and then check what slot you are on after reboot. I ran into issues flashing Havoc OS onto my phone too and figured it out in the end after so many times that I was in fact installing stuff twice on the same slot because it never switched over. I'll run you through the order I did things so hopefully you can follow.
-Use MSM Tool to revert everything back to stock and once the phone is booted, update to 9.0.9 either by downloading the update through the phone or by local upgrade if you have the file to hand. (remember to only have the OOS file present as any other OS in zip form crashes the local updater). You don't need to do this if you are already rocking stock Oxygen OS.
-Once the phone has restarted after the upgrade, let the post update procedure finish before continuing.
-Enter developer mode and enable OEM unlocking, Advanced Restart and USB Debugging. From here, reboot to bootloader.
-Plug your phone into the PC now and assuming you have fastboot setup ready on your PC, type 'fastboot oem unlock' and use the volume keys to select the option to unlock and press the power button to select.
-After the phone has completed it's wipe cycle, re-enable Advanced Restart and USB Debugging. The OEM unlock option should be greyed out as it's already been enabled. Make sure you don't add a pin code or password just yet as you will enable encryption which will make the next steps harder than it should be.
-Boot back to bootloader and type 'fastboot boot twrp.img' (or whatever you named it. Make sure that the image file is in the same folder you initiated cmd or powershell)
-Once booted into TWRP, flash blu_spark TWRP as that supports encryption apparently and is more stable than any other. To make sure that the script executed on both slots, hit reboot and check what slot you are on and tap the button for the other slot. Now reboot back to recovery, check you are on the other slot and flash it again.
-Now flash your 9.0.9 OOS zip followed by TWRP once on slot A and once on slot B while making sure you are on the other slot when doing it a second time. Remember that you have to re-flash TWRP after any flashable file that alters the boot partition before you reboot or you will undo all your work. Just make it habit that you re-flash it every time and you should be good.
-Once OOS and TWRP have been flashed on BOTH slots, reboot back to recovery and do the whole process again with your custom ROM (Remembering to flash TWRP before you reboot and checking which slot you are one before and after each flash).
-Once that has completed, reboot back to recovery and flash Magisk on each slot and GApps or MicroG if your ROM supports it. You don't need to re-flash TWRP after this but I do anyway to keep the habit lol.
-Entirely up to you, but before you reboot to your fresh new OS, you can wipe internal storage ONLY if you want all traces of your previous OS gone, but this will also remove personal files etc. I generally just head into TWRP file manager and delete the Android folder and keep the rest.
If you run into issues like crashes on your new OS, reboot to recovery and do a factory reset, but you will also need to re-flash Magisk again. GApps installs itself to system, so you won't need to re-flash that. MicroG does not and will need setting up again. One thing that took me a while to realise is that if you try rebooting while your USB is plugged into your PC, you will sometimes enter download mode, so only keep it plugged in when you need it for MSM Tool or to transfer files across.
I'm pretty sure I put everything down the way I did it and didn't miss anything, but it is late and I am half asleep. Will check back in the morning and double check with a fresh brain.
Many thanks for your exhaustive reply!
Will follow this tomorrow morning with a fresh brain
Fixed!
Now I'll write a guide for those in the same situation.

i tried all the mentioned steps, nothing worked for me. Even i tried all the guides, here on xda and on youtube i am not able to boot my 1+6 it is getting booted to fastboot mode, after installing custom rom. But if i flash only OOS then it boots back properly.
But in case of a custom rom it boots back to fastboot mode, and then in the end msm tool is the last resort to lock bootloader and make it stock.

If you are stuck on fastboot try
fastboot set_active other
then try rebooting recovery if fails try
fastboot boot pc-stored-twrp
I found changing the active slot via fastboot may unbrick it without msm. It all depends on what steps you actually take during installation.
For installing LOS try not flashing twrp after installation. Los comes with its own recovery. Anyway if it says no OS installed you HAVE to fix recovery bootloop.

Guide for rooting Realme 5 on stock rom.

I tried to root Realme 5 on stock ROM after a lot of failures and a visit to their service centre to flash stock ROM [It's free].
Code:
I am not responsible if anything goes wrong, this worked for me, I am not guaranteeing that this will work for you.
You should know the risks of rooting and mucking around where you are not supposed to be.
Code:
After rooting, stock ROM will show you an annoying red blinking pill in the status bar saying your phone has been rooted.
And no it can't be removed because xposed doesn't support our device.
Code:
You won't be able to set a pin or fingerprint after unlocking the bootloader.
Realme 5 is a pain in the ***, piece of **** phone if you want to root it with stock ROM.
1. Unlock the bootloader.
2. Flash twrp from fastboot mode. Download it from here.
3. Flash patched vbmeta immediately after flashing twrp. Download link.
4. Boot into twrp. Backup System, Vendor, Boot partitions on YOUR SD CARD [important].
5. Format Data (not wipe).
6. After formatting data download dm-verity disabler from here and flash it via twrp.
7. Now restore the backup you took before and download magiskmanager and flash it via twrp.
8. Boot into the system. Voila! your realme SHOULD boot up now with root.
The only thing I need now is a stock recovery for realme 5, can anyone please provide it?

Why there is need to restore backup ?

Because you have to remove encryption and to remove encryption the phone has to be formatted, After a format, you have to install an OS on it, in my case, it was the stock ROM, so I restored the backup of the stock ROM I had taken before.

No need to restore backup, because it only format userdata partition.
Help me my real 5 wifi and sound not work after instal root magisk..
My firm V A23
Or share boot.img V A23
Thanks for all

I specifically said FORMAT data, Format data deletes all of your partitions. Including system.
unlock fail
is there any method to unlock the BL?since mine realme 5 showed this is a carrier customized phone after i start depth test.......
by "patched vbmeta" do you mean that the vbmeta has the magisk? so after that I don't need to separately flash magisk too? just go to directly flash the dm-verity disabler?
proper root for rmx2030 didnt came out till now as i tried everything possible got root access and the device was open but as soon i restarted my phone went to bootloop

Flashed TWRP by accident, unable to boot to OS

Embarrased to say that I screwed up my phone pretty badly.
Series of events so far:
- Flashed TWRP by accident, thereby wiping everything
- Now unable to boot to the OS because I wiped the OS inadvertently
- Managed to access TWRP via fastboot
- Factory wiped and attempted to flash an oxygenOS zip through TWRP - didn't work
- Attempted to flash a new rom from fastboot using this tool - didn't work
- After using the tool above, the phone bootloops on the bootloader warning
- I am still able to access TWRP
EDIT: Solved. The only way to fix the phone was to use the unbrick tool for OP7.
