Can't flash latest TWRP, and lost my old install of it. Help?

Hi all,
I was running LineageOS 14.1 on my H830 with TWRP 3.2.1.0. Installed the newest nightly release via the OTA updater, which screwed up. System wouldn't boot, but I could get into TWRP. I ended up having to install it via the TWRP install option, and then had to run this code in TWRP's terminal:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc
to get out of the boot loop that I had.
Now I have the latest LineageOS, but I cannot boot into TWRP recovery. I have the TWRP app and have root from Magisk. I tried flashing via the app, and it gives me a success message, but when I try to boot into recovery either via the app or using power + volume, it takes me to fastboot mode. I tried flashing via adb, but this still didn't work (was getting Failed: remote: unknown command). Really need TWRP back, as I want to switch to XenonHD. Any help?
Update:
Solved thanks to @autoprime
Method (flash via dd):
dl latest twrp from h830 page on twrp.me
rename to twrp.img
place in same folder as install location for adb client (i use Minimal ADB + Fastboot)
push to /sdcard using adb client (adb push twrp.img /sdcard/twrp.img)
open adb shell (type adb shell)
type su
type appropriate dd command found on install guide on device page on twrp.me (in this case: dd if=/sdcard/twrp.img of=/dev/block/platform/soc/624000.ufshc/by-name/recovery)
if permissions denied even if you have root:
go to developer settings
enable local terminal app
open and type su
grant super user permissions
type dd if=/sdcard/twrp.img of=/dev/block/platform/soc/624000.ufshc/by-name/recovery
reboot into recovery via adb (adb reboot recovery) or via key combo (turn off, then hold power + volume down till lg logo, then let go of power for a second and then hold again until twrp appears)
and you're good to go!

[UNLOCK][ROOT][TWRP][UNBRICK] Fire HD 8 2017 (douglas)

Read this whole guide before starting.
This is for the 7th gen Fire HD8 (douglas).
Current version: amonet-douglas-v1.2.zip
NOTE: This process does not require you to open your device, but should something go horribly wrong, be prepared to do so.
NOTE: This process will modify the partition-table (GPT) of your device.
NOTE: Your device will be reset to factory defaults (including internal storage) during this process.
What you need:
A Linux installation or live-system
A micro-USB cable
Install python3, PySerial, adb, fastboot dos2unix. For Debian/Ubuntu something like this should work:
Code:
sudo apt update
sudo add-apt-repository universe
sudo apt install python3 python3-serial adb fastboot dos2unix
1. Extract the attached zip-file "amonet-douglas-v1.1.zip" and open a terminal in that directory.
NOTE: If you are already rooted, continue with the next step, otherwise get mtk-su by @diplomatic from here and place (the unpacked binary) into amonet/bin folder
2. Enable ADB in Developer Settings
3. Start the script:
Code:
sudo ./step-1.sh
Your device will now reboot into recovery and perform a factory reset.
NOTE: If you are on a firmware newer than 5.6.4.0, a downgrade is necessary, this requires bricking the device temporarily. (The screen won't come on at all)
If you chose the brick option, you don't need to run step-2.sh below:
Make sure ModemManager is disabled or uninstalled:
Code:
sudo systemctl stop ModemManager
sudo systemctl disable ModemManager
WARNING: Do not use bootrom-step-minimal.sh if you bricked using brick(-9820).sh!
You will need to use bootrom-step.sh.
After you have confirmed the bricking by typing "YES", you will need disconnect the device and run
Code:
sudo ./bootrom-step-minimal.sh
Then plug the device back in.
It will then boot into "hacked fastboot" mode.
Then run
Code:
sudo ./fastboot-step.sh
NOTE: When you are back at initial setup, you can skip registration by selecting a WiFi-Network, then pressing "Cancel" and then "Not Now"
NOTE: Make sure you re-enable ADB after Factory Reset.
4. Start the script:
Code:
sudo ./step-2.sh
The exploit will now be flashed and your device will reboot into TWRP.
You can now install Magisk from there.
Going back to stock
Extract the attached zip-file "amonet-douglas-return-to-stock.zip" into the same folder where you extracted "amonet-douglas-v1.0.zip" and open a terminal in that directory.
You can go back to stock without restoring the original partition-table, so you can go back to unlocked without wiping data.
Just use hacked fastboot to
Code:
sudo fastboot flash recovery bin/recovery.img
If you want to go back completely (including restoring your GPT):
Code:
sudo ./return-to-stock.sh
Your device should reboot into Amazon Recovery. Use adb sideload to install stock image from there. (Make sure to use FireOS 5.6.4.0 or newer, otherwise you may brick your device)
Important information
In the new partitioning scheme your boot/recovery-images will be in boot_x/recovery_x respectively, while boot/recovery will hold the exploit.
TWRP takes care of remapping these for you, so installing zips/images from TWRP will work as expected.
Don't flash boot/recovery images from FireOS (FlashFire, MagiskManager etc.) (If you do anyway, make sure you flash them to boot_x/recovery_x)
Should you accidentally overwrite the wrong boot, but your TWRP is still working, rebooting into TWRP will fix that automatically.
TWRP will prevent updates from overwriting LK/Preloader/TZ, so generally installing an update should work without issues (only full updates, incremental updates won't work).
For ROM developers there is still an option to overwrite these, which should only be done after thorough testing and if needed (LK should never be updated).
It is still advised to disable OTA.
Very special thanks to @xyz` for making all this possible and putting up with the countless questions I have asked, helping me finish this.
Special thanks also to @diplomatic for his wonderfull mtk-su, allowing you to unlock without opening the device.
Thanks to @t0x1cSH and @breakfastofsecrets for testing.

Reserved #3

Awesome!

if you can't get in the recovery by long pressing the volume buttons and power button simultaneously, during the boot keep both the volume buttons and fastly tap the power button
i had some problems getting by long pressing in the recovery and this worked every time

Works perfectly. Thank you very very much!

On a rooted device with a locked bootloader, if I back up system and data only with Flashfire, will I be able to restore these partitions with TWRP after unlocking? Presumably I wouldn't restore the boot partition?

I think that you can. TWRP supports flashfire backups but as you say don't restore boot.img neither recovery.img.

Haven't tested, but should work fine, also boot.img should give no issues when restoring.
Only userdata is erased during unlocking, so it should be enough to restore userdata.

Doesn't the unlock procedure include a factory reset which will wipe settings and apps? By 'userdata' do you mean 'data' or data plus internal storage (user files and photos etc.) or just internal storage?

Yes it does wipe data/userdata including the internal storage.
But it doesn't touch the system-partition.

Everything went super smooth. Many thanks for this, and all your unlocks.
Also, I was able to flash my flashfire system and usedata backups in TWRP with no issues.

How do you flash Flashfire backups? I now am unlocked and have TWRP installed, but when I try to restore, TWRP can see the backup folders but does not see any backed-up partitions.
---------- Post added at 10:49 AM ---------- Previous post was at 10:36 AM ----------
OK. I've got it figured out. You have to install the relevant 'twrp.zip' archives from the Flashfire backups.

dear friends
I make backup with twrp ( just system ) and transfer it to other device but when restore system the device stock on amazon i try to flash system by hacked BL flash success but when reboot also stock on amazon logo

Maybe you need to do a wipe of userdata and flash the latest boot.img.

thank you Rortiz2 i will try

I have unlocked three tablets now. It is very easy, thanks @k4y0z for making it that way. The only problem I had was with my first try on step 1, but that was because my adb and fastboot drivers needed updating.
Is a similar unlock planned for the HD 8, 2016/ 6th gen. Giza?

I still have problem in twrp restore my device now stock on amazon logo please help me

20e semi stock fastboo/twrp flashable images

Hey guys,
This is for people who already unlocked the bootloader!!
Since there hasn't been any flashable images via twrp or fastboot, I have decided to create one for the stock 20e. Now it's semi stock because the twrp is included with the boot image I uploaded. I'm doing just 20e because im too lazy to go back and forth firmwares just to upload different versions of fw of stock.
You can flash them via fastboot or twrp.
To access fastboot you need to be rooted in your custom rom or stock:
1. Use terminal or adb shell and do these commands
Code:
Su
dd if=/dev/zero of=/dev/block/bootdevice/by-name/laf_a
Then reboot and hold the vol+ button while it's plugged into the PC
Don't worry about losing download mode on slot_a cause the other slot will still have it and you can switch to the other slot via fastboot or twrp then you can have download mode
To flash via fastboot:
Code:
Fastboot flash boot_a twrpboot_a.img
Fastboot flash system_a system_a.img
Fastboot flash vendor_a vendor_a.img
To flash via twrp:
1. Move these files to your internal sd or external.
2. Get into recovery mode and then hit install
3. Tap on select image and find the image files
4. Then flash them one by one.
5. Format data and reboot.
https://drive.google.com/folderview?id=1-1tRMeDK7sVzta9kKhAvfVF2B9XZu2ki
If you want to help out and upload the other firmwares, here are the steps:
1. Be on the firmware you want to make the image files for.
2. Make sure you are rooted!!
3. Use terminal from the play store or use adb shell
4. And do the following for each partition.
A. First SU in shell then
For system-
Code:
dd if=/dev/block/bootdevice/by-name/system_a of=/sdcard/system_a.img
For boot:
Code:
dd if=/dev/block/bootdevice/by-name/boot_a of=/sdcard/boot_a.img
For vendor:
Code:
dd if=/dev/block/bootdevice/by-name/vendor_a of=/sdcard/vendor_a.img
Then upload them to Google drive or wherever and share them if you can.

Repeated update failure AND HOW TO FIX IT OnePlus 8t

I was in the process of rooting when the update was trying to run. Now I keep getting an install failure and can't seem to get any way to fix it.
Where is this update stored so I can delete it or can I get some advice on how to clear it so I can get it to try again?
I can't find the update for download anywhere :/

Not thing about file/cache. Incremental OTA need unroot frist.

Looking for the full installer package file for
11.0.8.12.KB05AA.​

Same let me know if you find it lol

OK good news I got myself sorted!
1. What I did was use "Oxygen OS updater" (can be found on playstore) with advanced mode enabled and downloaded the latest OS (11.0.8.11.)
2. Use local upgrade under settings to install 11.0.8.11 and restart. This will remove root but not user data or settings.
3. Check for and install update 11.0.8.12 under settings and it should install fine no issues.
4. Re root using your chosen method.
5. Done!

Interesting. How did you get the boot file for x.12? Isn't that required for rooting..

DroidFreak32 said:
Since we don't have TWRP yet for our 8T, having ADB enabled on the stock recovery can be really helpful if you are unlocked and rooted.
For example, removing problematic magisk modules.
I tried to install the EdExposed module and ended with a boot loop. To get back I had to flash the stock boot.img again and reconfigure all my modules again.
Having ADB enabled in OOS recovery will let us delete the problematic module at /data/adb/modules without having to delete the working modules.

CAVEAT
I've only tested this on my device (KB2005 / KB05AA), but it should be universally helpful as it's using your own boot.img so there's no need to find a matching package for your variant and os version.
CREDIT
The steps were buried across a few threads, I'm posting this so it'll be easier for others to find the information. All credit goes to xb360, FullOfHell, and TheUnkn0wn.
INFO​The basic rundown is:
Use the semi-broken TWRP package to give yourself temporary su access through adb.
Extract the boot.img your phone is currently using to your pc.
Reboot to OxygenOS, copy over the boot.img you just extracted and then use Magisk to patch it.
Copy the boot.img back to your pc and use adb to temporarily boot your phone with it, giving you root access until reboot.
Use your temporary root access to allow Magisk to patch your internal as-yet unmodified boot.img to give you permanent root.
There seems to be some confusion in the thread, I'll try to clear up what's happening and why:
The primary issue at hand is that you can't root your device without already having root privileges, for security reasons. Without a custom recovery like TWRP, there are a few more steps than usual (but mostly simple stuff).​
Because we don't flash anything with this guide, it shouldn't cause any permanent bootloops if you use the wrong boot.img, if you get stuck in one just power cycle your phone. ​
Updating with OTAs should be the same process as the other guides here.​
Because of changes in Android, devices that launched with Android 10 and above will not allow you to modify the system partition, even with root. This is not a fault of this rooting method.​
Prerequisites:
ADB and Fastboot installed.​
An unlocked bootloader and USB debugging enabled.​
________________________________________________________
STEPS:​
1. Connect your phone to your pc and boot it into fastboot mode. You can leave it connected throughout this guide.
2. On your computer open a terminal/cmd prompt. Set the directory (on your pc) you want to work from, I'm using the desktop:
for Windows, type cd C:\Users\Yourname\Desktop​for Mac, type cd desktop or cd /Users/yourname/Desktop​
Spoiler: How to set up adb and fastboot properly
To usb adb and fastboot commands outside of the folder those programs are located in, you'll need to add their location to the PATH list so your terminal can still find them when it's pointing to a different folder. If you want to skip this step, set the directory to the folder that contains adb instead of the desktop.
3. Next, use the terminal to check which A/B partition is active on your phone:
Code:
fastboot getvar all
a. You'll find it on this line: (bootloader) current-slot:a/b​b. For simplicity I'll be referring to boot_a.img throughout the guide, make sure to use boot_b.img if that's the one marked as active on your device. ​​
4. Download the semi-broken TWRP package to your desktop. We'll be using it to extract a copy of your active boot_a.img. It will give you temporary su access via adb, but there won't be a gui. Only boot from it, DO NOT FLASH IT:
Code:
fastboot boot recovery.img
adb shell
dd if=/dev/block/by-name/boot_a of=/sdcard/boot_a.img
exit
adb pull /sdcard/boot_a.img boot_a.img
adb reboot
5. Copy the extracted boot_a.img file to a user accessible area of your phone, like your downloads folder.
6. Install the latest Magisk Canary apk on your phone. Open it and:
a. Select the Install option.​b. Use Select and Patch a File on boot_a.img​
7. Copy the patched magisk_patched_a.img file back to your computer. In terminal, type adb reboot bootloader to get back to fastboot mode.
8. Temporarily boot with the patched image that corresponds to the active partition, DO NOT FLASH IT:
Code:
fastboot boot magisk_patched_a.img
Spoiler: Why we're booting and not flashing.
You could flash this boot.img, but it's safer to temporarily boot from it without overwriting your existing image in case anything went wrong along the way. The effect is that you still get root access without modifying your device, and then you can use the much safer Magisk direct install option, which has some safeguards in place.
9. By booting with the patched image, you now have temporary root access. To make it permanent open Magisk:
a. Select the Install option.​b. Use Direct Install (Recommended) to root your internal boot.img​
10. Reboot and verify it worked.

3. Check for and install update 11.0.8.12 under settings and it should install fine no issues.
4. Re root using your chosen method.
5. Done!

This looks like a great app but it won't work if you need to downgrade. The current release (11.0.8.12.KB05AA) is so bad (look at OnePlus forums) that OnePlus has even taken it down and is no longer available for download. The current one is the previous one (11.0.8.11.KB05AA). Because I have already installed the "12" release, the OxygenOS System Update will not let me downgrade to the "11" release. It gives a "to avoid booting up failure, downgrading is not allowed" message.
Can I sideload/flash this "11" zip file via ADB and accomplish my goal of downgrading? Or could I change the active slot to the inactive one, reboot and get back to "11" that way?

Well I tried switching slots but the inactive slot was corrupted from earlier. So I do not have an "11" in the other slot.

Since OP 8T OxygenOS does not have a recovery, ADB sideload will not work.

Now that 11.0.8.13 is out and I'm on 11.0.8.12 right now, and so far I haven't come across a full zip for 13 yet. Not sure, if this will work .. but I'm thinking, I will uninstall magisk via the app. Restart to ensure, I'm unrooted and then do an OTA to 13. After the OS has been upgraded, follow the steps to root the boot dump file. Anyone tried this method and if would work? The 2 things I'm worried about are - 1) if I uninstall Magisk via the app, does it fully unroot and allows OTA, 2) will the broken twrp shared above work on the latest OOS x.13?
Thanks!

For anyone who's interested. This worked!

Hey little bit of an add in! Keep a backup of your non Rooted boot.img!! It is actually easier to flash the non rooted and update just to reroot again.

Oneplus 8T Rooted issues with reboot

I'm on 8T latest OOS 11.0.8.13 and rooted with magisk.
Something I've lately noticed is every time I restart it ends up on a long wait on the initial bootloader unlocked disclaimer and ends up in recovery mode. Removing cache generally reboots back into the OS.
This happens on every restart. Pretty irritating.
Are other rooted users facing the same?

Quick and concise how to for obtaining a Stock Boot Image from your Oneplus 8, 8T or 8 Pro device and patching with Magisk to create a fastboot flashable patched boot.img.
DISCLAIMER:

PREREQUISITS:
An unpatched Stock Boot.img running on your device
General knowledge and understanding of ADB and Fastboot
Download latest op8, op8p, or op8t Horizon Kernel img from [e.g., op8p_7.img]:
https://dl.akr-developers.com/?dir=oneplus/horizon_kernel/R/images
Download latest Magisk Canary build from Github [e.g., app-debug.apk]:
https://raw.githubusercontent.com/topjohnwu/magisk_files/canary/app-debug.apk
DEVICE/PC OPERATIONS:
→ ADB
Enumerate devices
Code:
adb devices
Boot into Fastboot
Code:
reboot bootloader
→ FASTBOOT
Enumerate devices
Code:
fastboot devices
Determine the current slot (A/B), whichever slot you're on should be the "good" img
Code:
fastboot getvar current-slot
Boot with the custom kernel downloaded from Horizon to use root [NOTE: Include the full path of the img if not in the same directory]
e.g., fastboot boot "C:\Users\User\Downloads\op8p_R7.img"​
Code:
fastboot boot xxxxxxx.img
→ ADB
Copy the boot.img from each slot to the root of the device
Code:
adb shell
su
dd if=/dev/block/sde11 of=/sdcard/boot_a.img
dd if=/dev/block/sde35 of=/sdcard/boot_b.img
→ Android Device [NOTE: Some Android 11 devices experience patching issues on the Beta Channel like bootloop] [NOTE: Some users experience issues on Canary like no SIM detected; if so switch to Beta]
Install Magisk app-debug.apk (Canary)
Go to Settings → Update Channel → Canary
Go to Home → Install → Install → Select and Patch A File
Navigate to internal storage and select the stock boot.img [choose the img from whichever slot you're on]
When it’s done patching copy the file, named magisk_patched.img, from the root → Downloads of your device to PC
→ ADB
Code:
reboot bootloader
→ FASTBOOT
Test to ensure it boots before flashing; if not you'll need to patch the other img
Code:
fastboot boot magisk_patched.img
→ Android Device
If the device boots and you have root in the Magisk Manager app, reboot the device into Fastboot then flash the active slot [NOTE: Both slots do not need to be flashed; just the current active slot]
→ FASTBOOT
Flash the patched image file [NOTE: Include the full path of the img if not in the same directory]
e.g., fastboot flash boot_b "C:\Users\User\Downloads\magisk_patched.img"
Code:
fastboot flash boot magisk_patched.img
fastboot reboot
- OR -​
Code:
fastboot flash boot_a magisk_patched.img
fastboot reboot
- OR -​
Code:
fastboot flash boot_b magisk_patched.img
fastboot reboot
ADDITIONAL RESOURSES:
→ FASTBOOT
If you need to set the other slot to be the active slot use:
Code:
fastboot --set-active=a
- OR -​
Code:
fastboot --set-active=b
→ ADB
ADB Magisk Bootloop Fix
Code:
adb shell
magisk --remove-modules
→ OTA Help
Magisk stock boot.img missing fix [NOTE: Android 11 onwards, the /sbin folder might not exist, so Magisk will randomly create a folder under /dev and use it as the base folder]
Rename to: stock_boot_0.img
Compress with gzip = stock_boot_0.img.gz
Copy stock_boot_0.img.gz file to the root of: /data
Edit the config file: /dev/xxxxxxx/.magisk/config → Change SHA1= to 0
Magisk Manager → Uninstall Magisk → Restore Images
→ ADB
Determine the random folder name generated by Magisk on Android 11+
Code:
ls -laR /dev | grep '.magisk/rootdir'
→ ADB
Determine the Boot Image partition location [NOTE: Will list all partitions; look for boot_a and boot_b]
Code:
ls /dev/block/bootdevice/by-name/ -all

Root with this method probably because of something wrong with the installation or smth.

Rooted using the same guide.. Use the same after each upgrade (full package).

huh, have you updated the kernel and stuff. There are newer releases.
Might be your problem

Adaway and Ktweaks apps, but both execute after boot.
Systemlesshosts (to run Adaway) and Oneplus phone dialer modules on Magisk.
Checked, no newer version for any mentioned.

Use full update.zip update again, see if it can be fix
