Oneplus 3T flashing issue

I have a stock Op3T from China with hydrogenOS, I'm trying to flash lineage 14.1 onto it, but it's having alot of issues where it just won't take on the rom, it'll start up but then just delete the rom? I'm not quite sure whats the issue here is as according to all my research it shouldn't matter if it's on hydrogen or oxygen, please help as I can't possibly use the phone as it is as it does not have any google framework what so ever.

you could just install google framework on hydrogen os using google installer:
https://docs.google.com/uc?export=download&id=0B0l2sjcF9VU2WkFyWjQxT21pSUU

I really dont like hydrogen's look and since its from china it has alot of chinese pup's and bloatware

I would just use the Qualcomm recovery solution to restore OxygenOS to the phone and update to the latest to get the matching hardware firmwares that are compatible with LineageOS (4.17), and then unlock the phone and install TWRP through fastboot. From there you should change filesystem of the data partition to ext4 (this will remove all your data from phone, so make sure you've backed up everything first) and format data and system. The adb sideload the latest LOS zip and Gapps nano package and reboot the phone (it will say that you don't have any OS installed, just ignore and continue reboot and it will boot up LineageOS).

I tried as you said, but doing the third party recovery killed the phone and i had to rebuild the cache from scratch, and when i booted it, it was back to hydrogen OS, is there any other way to do this?

What about just adb sideloading the latest OxygenOS full zip using adb sideload nameoffile.zip when phone is in recovery/adb sideload mode and with adb driver installed in Windows? (this will probably require that you disable driver signature check temporarily unless you're running Windows 7 or older)

thats the thing, i have been using adb, but i was wondering, does root access or custom recovery need to be present for sideloading or should a clean force abd sideload do?

Well, I wasn't talking about ADB recovery earlier but instead this one as it should be able to convert your phone to OxygenOS and from there to whatever ROM.

MiX Pack for the simple user (TWRP AdAway SuperSU)

Hi all,
Here you may find a zip containing some very basic resources which can be found elsewhere without too much effort however I figured I would make things that slightest bit easier for some who use any of the MIUI 9+ builds.
The following zip file includes the latest custom SuperSU for MIUI Oreo, the latest release of TWRP, the latest release of AdAway.apk and for the hell of it, the stock MIX boot animation if you wish to use it on any other ROM. 20/5/18
https://www.dropbox.com/s/29u1z721blc1mdy/MIX Package.zip?dl=0
You can find guides elsewhere which go much more in-depth but I'll make a quick one for those who have unlocked bootloaders and are wanting to use any of the builds located on the official MIUI site: http://en.miui.com/download-334.html
The following are the steps I take for my usual installation;
1. Download chosen Official Developer or Stable ROM from the site above in FASTBOOT version. (Click "flashing guide", then "fastboot update" on the left menu where you will find all Xiaomi models, select either "latest global stable" or "latest global developer")
2. Extract ROM folder from download (example: chiron_global_images_8.4.19_20180419.0000.00_8.0_global) to C drive root.
3. Make sure fastboot drivers are installed and device can be seen by PC then download: https://xiaomiflashtool.com/
4. Connect your phone, load up the tool and click "select" on the top left. Here you will locate the ROM folder on C drive.
5. Click "refresh", if your phone is discovered then click "CLEAN ALL" at the bottom to prevent re-locking your bootloader followed by "flash" on the top right hand side which will initiate a full wipe of your phone followed by the installation of your ROM.
When complete allow phone to boot completely and then power it off. Continue below for root instructions.
6. Extract contents of MIX Package to your desktop and open CMD: Hold shift and right click your desktop, click "open powershell window here". Once powershell is loaded, type "cmd" and hit enter. When ready for step 7, boot your phone to fastboot mode.
7. You can either install TWRP or single-boot to it which will allow you to use it one time before reverting to stock recovery upon next reboot. For install, type "fastboot flash recovery recovery.img" and hit enter, then type "fastboot boot recovery.img" to boot to recovery. For single-boot TWRP type "fastboot boot recovery.img" which will boot into the img and allow any desired flashing without installing TWRP to your phone.
8. You are now in TWRP and should have storage access to your phone via your PC, copy SuperSU (and AdAway if desired) to your phone storage.
9. Hit "Install" in TWRP and select SuperSU zip file then flash. Once complete you may now boot your phone and progress through the first time setup.
10. Congratulations, you now have a completely fresh, clean rooted version of your desired MIUI. If you wish to enable full-system ad blocking, proceed to your file manager and install the AdAway.apk then follow instructions in-app.
As mentioned, this is not particularly a replacement for any other guide already published for the Mi Mix 2, it is the guide which I follow for all of my installations which gives me the cleanest possible MIUI. If you are using a stable release ROM and need to pass safety net then I suggest you use substitute SuperSU for Magisk however all the developer ROMs are unable to pass safety net anyway and I much prefer using SuperSU as it has never failed me and has the ability to hide the icon completely from launcher.
Kaji.

[GUIDE][TREBLE] How to erase ghost fingerprints

Surely, some Huawei P9 owners are flashaholics like me. I've rebranded, danced left and right with OTAs in order to install EMUI 8.0 and the B540 firmware, juggled recoveries up and down and played with numerous Treble ROMs. If you're like me, you have soft bricked your device numerous times, or you did factory resets from AOSP without erasing the fingerprints first. The issue is, when you forget to wipe your fingerprints and factory reset, they are gone from AOSP ROMs, but not from the sensor hardware, which leads to the issue of ghost fingerprints.
What are ghost fingerprints? Fingerprints that occupy a space in the fingerprint sensor's memory without being registered as existing in pure Android. This causes issues at the moment of registering a new fingerprint since the sensor won't register an already occupied fingerprint which leads to the enrollment not being completed on that fingerprint, reducing the available number of registerable fingerprints and being a security issue as the ghost fingerprints are recognized by an active sensor as valid even if they are not the fingerprint registered in Android.
But there is a (painful) solution, fortunately. Your fingerprint sensor is not crippled for life. This guide involves flashing several times so be careful when following it and investigate every step. I am not responsible for soft or hard (OOF, my wallet hurts) bricked devices. Also this guide is intended for rebranded P9s running a Project Treble compatible firmware stack.
I DO NOT support people running EMUI 5.0 B3xx pre-Treble firmwares or older on their phones. You need a modern B5xx firmware with the new bootloader and partition layout of EMUI 8.0 to follow this guide.
NOTE: This tutorial involves formatting the internal storage. There WILL be data loss.
First, you need the following:
* The update.zip file of the EXACT SAME EMUI firmware image that you are using
* A computer with ADB drivers and an ADB and Fastboot stack.
* Any keyboard APK (I'll explain later)
* The Huawei Update Extractor
* The ROM image of your AOSP Treble OS.
* A Huawei P9 with an unlocked bootloader, an EMUI 8 firmware installed, and/or running any AOSP Treble ROM.
PART 1: Preparations
1. Open your firmware's update.zip in any ZIP file manager.
2. Extract the 'update.app' file to the location of your ADB and Fastboot stack.
3. Open the Huawei Update Extractor in your computer.
4. Disable the signature verification checks.
5. Right click and extract the following images: SYSTEM.img, and if you use a custom kernel, KERNEL.img. After that you can close HUE.
4. Enable developer options, and turn on USB debugging.
PART 2: Going back to EMUI
1. If you have Magisk, uninstall Magisk and everything that depends on Magisk.
2. Open a command prompt or terminal, depending on your computer's OS.
3. Connect your device to USB, and confirm that it can interface with ADB using 'adb devices'.
4. 'adb reboot bootloader': This will reset our device into Fastboot mode.
5. Confirm that communication with Fastboot is possible by using 'fastboot devices'.
6. If you were using a custom kernel, do...
'fastboot flash kernel KERNEL.img'
This will reflash the original kernel image that came with your firmware update.
7. Verify that your device has at least 20% battery, just to make sure that it will work if your battery is old or faulty.
8. The actual procedure.
'fastboot flash system SYSTEM.img'
Have patience. We're flashing the stock ROM through Fastboot now.
9. 'fastboot reboot'
Self explanatory. You can disconnect your phone now.
10. Keep Volume Up to boot to your recovery image, whatever are you using.
11. Do a factory reset, then reboot. This is required to switch between AOSP and EMUI ROMS, and recommended when switching any ROMs in general.
PART 3: Making the ROM usable
1. Skip through the first time wizard.
2. Enable developer options.
3. Go to developer options, enable USB debugging.
4. Connect your device, enable file transfer.
5. Accept the RSA key of your computer, and do 'adb devices' to make sure you can communicate with ADB.
6. 'adb install keyboard.apk'
This will install a virtual keyboard, as our barebones EMUI 8 lacks one. This ROM is not usable in this state, so don't keep it.
PART 4: Killing the ghosts and leaving the battlefield
1. Configure your lock screen, put a short PIN, then go to the fingerprint settings. Your ghost fingerprints will be there, exposed to the light thanks to EMUI's dark magic.
2. Delete each fingerprint. You cannot leave any fingerprint.
3. 'adb reboot bootloader'
4. 'fastboot flash system my-aosp-treble-rom.img'
Be patient. We're returning to AOSP once more.
5. 'fastboot reboot'
6. Boot into recovery
7. Do a factory reset.
8. Disconnect your phone and reboot to system for the last time.
Your ghost fingerprints are gone. Now you can enjoy your clean fingerprint sensor once more.
And remember, make sure to flash responsibly the next time!

!DISCLAIMER!
Most people I know (including myself) who used my Guides and steps, did that with success many times. If you don't follow exactly the steps or you do a mistake during the process, I do not take any responsibility for any unexpected results or damage that may happen. However I am here to help if something goes wrong, just ask in the thread.​
AMD RYZEN FASTBOOT FIX
Some AMD Ryzen Systems may have problems to recognize your device in fastboot. Try the following ways:
1. Install AMD Ryzen Chipset Drivers.
2. Enable USB Debugging at device (Settings > Additional settings > Developer options > USB Debugging) and give authorization after connecting it to PC.
3. Use USB Hub.
4. Use USB Type-A 2.0.
5. Download this .bat file (unzip it) or manually create a .bat file with these lines below, and run it as an administrator, then reboot:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "osvc" /t REG_BINARY /d "0000" /f​reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipContainerIdQuery" /t REG_BINARY /d "01000000" /f​reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\18D1D00D0100" /v "SkipBOSDescriptorQuery" /t REG_BINARY /d "01000000" /f​Check the steps an another user did to make it work here.
If this doesn't help, unfortunately you have to use Intel System.
UNLOCK BOOTLOADER
Note: Some AMD Ryzen Systems may have problems to recognize your device in fastboot. [Read the AMD Fastboot Fix Guide above]
Please keep in mind by Unlocking Bootloader the device will reset and all your data will be lost. Make a backup of your data first to PC or to USB.
1. Create a Mi account on Xiaomi’s website.
2. Add a phone number to your Mi account.
3. Insert a SIM into your phone (If you haven't added already).
4. Enable developer options in Settings > About Phone by repeatedly tapping (7 times) on MIUI Version.
5. Link the device to your Mi account in Settings > Additional settings > Developer options > Mi Unlock status. Also enable USB Debugging.
6. Download the Mi Unlock app (Windows is required to run the app).
7. Run the Mi Unlock app and follow the instructions provided by the app.
8. Reboot your device into Fastboot mode. For that simply turn off your device, press the Power Button + Volume Down (–) button at the same time. Then connect the device to the Windows PC/laptop via a micro USB cable.
9. After device and Mi account are successfully verified, the Bootloader should be Unlocked and your device will restart by itself.
INSTALL CUSTOM RECOVERY
Fastboot Method (No Custom Recovery currently installed)
Note: Some AMD Ryzen Systems may have problems to recognize your device in fastboot. [Read the AMD Fastboot Fix Guide above]
1. Make sure your Bootloader is Unlocked.
2. Enable developer options in Settings > About Phone by repeatedly tapping (7 times) on MIUI Version.
3. Enable USB Debugging in Settings > Additional settings > Developer options > USB Debugging.
4. Download a custom recovery of your choice. [You can find a recovery of your choice in my Collection]
5. Download the portable Minimal ADB and Fastboot and run adb.exe
6. Reboot to Fastboot mode by pressing Power Button + Volume Down (–) and keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
7. Once the device is in Fastboot mode, connect your device to PC and verify you can find it by typying in adb: fastboot devices.
8. Flash Recovery by typing in adb: fastboot flash recovery <recovery_filename>.img (The file may not be named identically to what stands in this command, so adjust accordingly).
9. Reboot to Recovery by typing in adb: reboot recovery or manually hold Power Button + Volume Up (+) until you boot to Recovery.
10. Done! You now have a new Custom Recovery installed.
Recovery Method (Custom Recovery already installed)
1. Download a custom recovery of your choice. [You can find a recovery of your choice in my Collection]
2. Reboot to Recovery by holding Power Button + Volume Up (+).
3. Press Install Image.
4. Locate the recovery.img you recently downloaded.
5. Select it and choose the option Recovery and Flash.
6. Go back and Reboot to Recovery.
7. Done! Your new recovery should be installed.
MAGISK ROOT SOLUTION
The easiest way to root your device is via Magisk, it should work in all ROMs, Stock and Customs.
Install Magisk:
1. Install latest TWRP Recovery. [Read the Install Custom Recovery Guide above]​2. Download the Magisk [You can find it in my Collection]​3. Reboot to TWRP Recovery by pressing Power Button + Volume Up (+) and flash it.​4. Reboot and check whether the Magisk app is installed. If it isn’t installed automatically, manually install the APK. [You can find it in my Collection]​Note: From Official TWRP Recovery 3.5.1 and onwards (and other recoveries based on that), Magisk.apk can be flashed as apk without the need of rename it to .zip. So you can simply flash the Magisk.apk in TWRP.​Manually Creation of Flashable Zip:​Download the latest Magisk APK and rename the Magisk.apk → Magisk.zip.​
Uninstall Magisk:
Flash the Uninstall.zip in TWRP Recovery and reboot. [You can find it my Collection]
If Magisk App isn’t uninstalled automatically, manually uninstall the app.
Manually creation of Flashable Uninstall Zip:
Download the latest Magisk APK and rename the Magisk.apk → uninstall.zip
Uninstall Magisk directly through the Magisk app. Simply press the Uninstall button.
DISABLE FORCE ENCRYPTION (DFE) & Encryption
[You can find it in my Collection]
Disable Force Encryption
Disable Force Encryption (a.k.a DFE) is flashed during installation of a custom ROM to avoid the system encrypting /data partition when the devices boot for the first time.​Some ROMs are not encrypted by default and so is not necessary to flash DFE. However if your ROM comes with encryption by default you can always flash DFE after clean installation of ROM and always after every update or flash or you can use any custom recovery like OrangeFox, Pitchblack, Skyhawk Recovery Project which can automatic flash DFE after every flash.​I don't recommended to use DFE if you don't switch ROMs frequently and you are casual user. Beside the fact that if you lose your device your data are not protected, many people get in confusion while doing OTA or manually updates, which if the ROM is encrypted by default and flashed DFE and in next update you forget to flash DFE you will lock out from your data and you wil get into bootloop (use custom recoveries mentioned above to avoid that).​​
Encryption
Warning - This works only on clean flash:
1. Flash ROM.zip in recovery
2. Mount vendor partition in recovery (for some reason does not mounting with newer TWRP).
3. Flash encrypt.zip.
4. Reboot to system.
Note:
The encrypt zip needs to be flashed after every update.
So flash ROM.zip and follow with encrypt zip.
Encrypted ROMs are recommended if you are stable and casual user of a ROM. Encryption have the benefit to protect your data, in case you lose your device for example. ​Always use the latest TWRP Recovery so you can be able to decrypt the data by filling the same lock screen password you have set in ROM.​Some ROMs are not encrypted by default but devs provide an Encryption.zip (script) which can encrypt the ROM. Same as DFE you need to flash it after clean installation of ROM and always after every update to stay encrypted and not get into bootloop. Unfortunatly there is not any custom recovery automatic doing that like with DFE, so you must be careful, avoid doing OTA updates and flash it every time you manually update a ROM.​
BATTERY TIPS
Advanced Guide
Simple Battery & Charging Tips
Improve your SOT
Battery Calibration
Steps:
1. Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
5. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
6. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
Overheating
Following reasons will lead to device heating issue:
During the initial setup after purchase or when restoring data.
Downloading large files.
Using apps that require more power or using apps for extended periods such as:
Playing high-quality games for long time.
Recording videos for extended periods.
Streaming videos while using the maximum brightness setting.
Using the Screen Mirroring / Smart View feature (connecting mobile to a TV).
While multitasking or when running many apps in the background i.e:
Using Multi window.
Updating or installing apps while recording videos.
Downloading large files during a video call.
Recording videos while using a navigation app.
Large amount of data for syncing with the cloud, email, or other accounts.
Exposing device under sunlight when temperature is high around you.
Extensive usage of mobile hotspot and tethering feature.
Using device in areas with weak signals or no reception or in roaming network.
Charging the battery with a damaged / unapproved USB cable.
Device's multipurpose jack is damaged or exposed to foreign materials, such as liquid, dust, metal powder, and pencil lead.
Solution:
Turn off Wi-fi, GPS , bluetooth and other connectivity options when not in use by dragging the notification panel.
Decrease screen brightness.
Close background running applications.
Too many applications installed in device may result in device heating since their corresponding process will keep on running in background. It is advised to uninstall un-necessary apps if not using them.
Avoid using apps like GPS, data dependent apps or graphic intensive games for longer duration since they require more energy to function, causing device to heat.
It is advised not to use device while charging as it may cause the device to over heat.
General:
DO:
Use manual brightness or dim the screen.
Turn off notifications for apps you don't use. Better still, delete/disable the apps entirely if you don't need them.
Enable battery or power saving mode when you want to extend your battery life.
Use the power adapter that came with your phone. Other chargers can charge slowly/faster but they can also damage your phone or battery.
Turn off bluetooth, location tracking, and Wi-Fi (unless you are actively using it)
Turn off print services from bluetooth connection preferences.
Avoid extremes of heat and cold. If your phone gets very hot or cold it can strain the battery and shorten it's lifespan.
DON'T:
Have Bluetooth or Wi-Fi turned on constantly.
Leave apps running in the background. Instead restrict background usage off apps that you don't need running.
Push email means your device is always listening for new email which drains alot of battery.
Drain your phone battery all the way to 0% or charging it all the way to 100%. Keep it between 20% - 90% for longer battery lifespan.
The more advanced the graphics and animations are (games, videos, photos, animations), the harder the processor and graphics chip in your smartphone have to work. More activity means more battery use.

Always download and install Apps, Programs, ROMs & Stuff from official sources and do not use redirection links from different sites. Google is your friend to find the official source of the stuff you want.
Always check the permissions an app requires, before download and install it to your device. If an app ask for permissions which has nothing to do with the app functionality then it's should be reconsider or ask the developer why these permissions needed.
If you want to avoid Google and Play Store (De-Google), you can choose a ROM without GApps preinstalled like LineageOS and use F-Droid client which is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device. Note that not all apps from Play Store will be available in F-Droid. Only Open Source projects. You can find alternatives though.
Alternative you can use LineageOS for microG or any ROM which support signature spoofing and can support microG.
For Windows use the default Windows Defender & Malwarebytes to scan your files whenever you want (Prefered before open or install them). Also use the addon/extension uBlock Origin in your Browser. These should be enough for normal users.
For Android Do not use any antivirus - antimalware since it's useless, just check what apps and from where you installing.
Always verify the source of addons/extensions in your browser. Avoid installing random and unpopular addons/extensions. Keep it minimal and clean, so browser can be fast and safe, no need bunch of extensions.
If you are using VPN, always check the terms and rules of the provider. Avoid random VPN Services.
Recommended VPN Services.
Using a VPN will not keep your browsing habits anonymous, nor will it add additional security to non-secure (HTTP) traffic.
Recommended is to encrypt your data/files always before uploading them to cloud with tools like Cryptomator.
Always use unique and strong passwords for each of your accounts.
Use awarded open source Password Managers like KeePass or KeePassXC for Desktop and KeePassDX for Android to manage your passwords and have them with you safe, encrypted and secure. Must be noted you can use the same database file between these programs.
Always enable 2 Step Authentication wherever is available for your accounts.
You can use apps like Aegis Authenticator.
Do not open or click on links attached in unknown emails you may get. Always check the adress of the email and verify it's legit from the official source.
Create and use "burned" email for accounts/sites you have concerns but you definitely want to try them. Do not use your personal or business email.
CLEAN INSTALL CUSTOM ROM
You can also do the same steps below to install Stock MIUI Recovery ROM.
1. Backup all your data to PC or to external SDCard. [All your data into Internal Storage will be lost on step 7 while Formating Data or Wiping Internal Storage]
2. Unlock Bootloader. [Read the Unlock Bootloader Guide above]
3. Download: [You can find everything in my Collection]
Custom Recovery of your choice.
Custom ROM of your choice
GApps (be sure you have selected Platform: ARMx64 and the proper Android version of the ROM you are going to flash) if the ROM you are going to flash does not include. [Optional]
Magisk Root Solution [Optional]
Disable Force Encryption [Optional]
4. Move all these files in one folder to your Internal Storage or to External SDCard if you have.
5. Install Custom Recovery. [Read the Install Custom Recovery Guide above]
6. Reboot to Recovery Power Button + Volume Up (+)
7. Installation:
Steps without external SDCard:
Select Wipe > Advanced Wipe
Select Dalvik / ART Cache, System, Data, Vendor, Cache and then Swipe to Wipe.
Flash ROM > GApps [Optional] > Magisk [Optional] > DFE [Optional - Not Recommended]
Go back and select Wipe > Format Data > type yes [All your data into Internal Storage will be lost]
Reboot Enjoy!
Steps with external SDCard:
go to Advanced > File Manager > External_SD and delete all folders in ur ext sd card (For example you should delete: Android, .android_secure, LOST.DIR, DCIM, etc) except your personal files/folders and the folder with your custom ROM/Gapps/Magisk/DFE you want to flash.
Each app on your phone with the WRITE_EXTERNAL_STORAGE permission may create files or folders in ur sdcard. Most of these folders have once been created by one of these apps and many of them may be deleted with a few exceptions (e.g. Android, .data, .android_secure, these contain important system or app data like a game's downloaded content):
.android_secure: apps installed and then moved to sdcard
Android: app data/cache
data: app data
.estrongs: ES file manager
LOST.DIR: sort of trash folder (collects recovered files after phone crashes)
DCIM: phone gallery's photos and previews
OTA-update: Over The Air update service
ppy_cross: an unknown third-party app's data.
So I recommend to delete them so you can put your phone/sdcard in a clean state and is guaranteed to be able to re-create these folders.
Select Advanced Wipe
Select Dalvik / ART Cache, System, Data, Internal Storage, Vendor, Cache and then Swipe to Wipe. [All your data into Internal Storage will be lost]
Flash ROM > GApps [Optional] > Magisk [Optional] > DFE [Optional - Not Recommended]
Go back and select Wipe > Format Data > type yes [All your data into Internal Storage will be lost]
Reboot Enjoy!
DIRTY INSTALL YOUR CUSTOM ROM
Note: Before you start flashing, keep in mind the ROM you dirty flashing MUST be the same with the one you have already installed.
1. Make a full nandroid backup, just in case something goes wrong. You can use TWRP to do that. (TWRP > Backup > Select everything) [Optional]
2. Remove all Magisk modules. [Optional]
3. Reboot to TWRP and Wipe Dalvik / ART Cache, System, Vendor, Cache.
4. Flash the ROM > GApps [Optional] > Magisk [Optional] > DFE [Optional - Not Recommended]
5. Reboot and Enjoy!
I've skipped some explanations, because if you are going to dirty flash, you already know for example how to boot to TWRP.
CLEAN INSTALL OFFICIAL STOCK MIUI ROM & RELOCK BOOTLOADER

Links to Custom ROM is broken ???

Question Touch Issue only on A12 ROMs

Hey, my 9 power has an NVT-TS touch panel. All android 11 based ROMs seem to work such as Pixel Blaster and Lineage. However, when we talk about Android 12, my touch seems to only work on Evolution X.
I tried installing PixelPlusUI and PixelOS, however my touch does not work in them. If I try installing a custom kernel with those two, the OS does not boot and the phone gets stuck on the Redmi boot logo.
I have tried many fixes from various threads but nothing seems to work.
Anybody with a workaround or suggestion?

Update: Only a previous version of EvoX works. The latest version does not boot.

Hi. What kernel and recovery did you used for a12 rom ? Can you put here links to twrp/kernel and roms used in process ? Thanks. I have the same model with nvt touch and nothing worked for me and now i'm back to stock miui 12.5.11 global.

I used PitchBlack Recovery but also tried 2 different TWRP and Orange Fox Recoveries. I tried flashing various kernels but none worked. In the end, the kernel within the evox rom itself had to be used.

Hello,

Hi. What type of screen do you have ? Can you put the link here to download what rom you installed ? Thx.

I have the exact same type of screen than you, NVT-TS
I downloaded the rom from the official website of CrDroid : https://crdroid.net/juice/8
For the stock zip (step 11), i used this one : https://sourceforge.net/projects/xi...i_HMNote94G_HM9T_21.11.24_v12-11.zip/download

Btw, use crdroid 8.6 for juice. ATM 8.7 don’t work with touchscreen afaik. I did have to reinstall 8.6 after update

Thank you, crdroid 8.6 worked. However, I wanted to use ROMs like Pixel Experience and PixelPlus but they touch does not work on them.

Atm, PixelPlusUI or PixelExperience are A12 AOSP with integrated Gapps (probably others differences but no matter), use flamegapps to get full gapps package and there you go!
Atm, i tried a lot of roms, and with A12, only CrDroid8.6 works...
