[RECOVERY][STABLE]Unoffical TWRP for Xiaomi Mi A3[laurel_sprout]

[Nik001]

Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Stock fw 10.3.8 (global) not booting with this twrp - in 10.3.8 audio modules have strange dependence "saved_command_line" symbol from kernel. For loading this modules need patch kernel sources -

Proper install method explained

Hello!

Please, @Nik001, update the OP with the install method that I'm going to describe next, ok?

It's just to avoid future complications (lost of Wi-Fi, sound, etc...) for "not that experienced users".

1. Your bootloader must be unlocked. If it's not, then follow step 1 of the instructions provided HERE.
2. Download TWRP zip file and copy it to your device (internal or external storage)
3. Download TWRP img file and and store it, on the folder where you have adb and fastboot files, on your PC
4. Open a cmd line and execute these commands (being on that folder, of course):
   
   adb devices (to make sure your device is detected)
   adb reboot bootloader (to reboot into fastboot mode)
   fastboot getvar current-slot (to check what's your current active slot)
   fastboot set_active b (if your active slot was a, if it was b then change it to a)
   fastboot erase boot
   fastboot flash boot twrp-3.3.1-2-unofficial-laurel_sprout.img
   fastboot reboot (NOTE : Before hitting "Enter", long press Vol + on your device until you see the Android One logo. By doing this your device will be forced to boot into Recovery and not into System)​
5. When TWRP recovery boots, if you have a stock boot.img that matches the build on this "currently active" slot, flash it into boot partition. If you don't have, then just ignore this step...(it's not mandatory)
6. Install the TWRP zip (always install the latest build available)
7. Change slot to the one that was active on the beginning of these steps and reboot to Recovery (just to make sure that the slot, in fact, was changed)
8. Reboot to System

Why do I suggest this?

By doing this method (which seems more complicated but, trust me, it's how it should be done) we will flash TWRP img into the "inactive" slot, thus, not breaking anything on the "currently active" slot. When TWRP boots, it will patch both slots boot ramdisks. But the thing is, on the "currently active" slot (the one inactive on the beginning) it will patch the TWRP img but, on the "currently inactive" slot (the one that was active on the beginning), it will patch the stock boot.img, thus, no bug will happen that usually appears when a user accidentally flashes the wrong boot.img into boot partition.

On the other hand, if we have a stock boot.img, that matches the build on the "inactive" slot, we could flash it into boot partition before installing the zip that patches ramdisk. By doing this we will patch both stock boot.img present on both slots (instead of patching TWRP img and boot.img).

Cheers!

 

[Typhus_]

The method Typhus shared works 100% of the times; however I must say, I don't use it, just preference; as it follows, instead of flashing into the inactive slot, I flash the pre_patched boot image into the active slot, this of course will mostly like break network and other components on the ROM, if you mismatch image versions; however, if you flash the stock boot image (using install button, inside TWRP, tapping into 'images', select your stock boot.img) and then patch it using the TWRP Installer right after, you will be using the right image, so no problem will occur, and mostly important, no slot change is needed. Both methods works, choose what you prefer, just read it carefully and I repeat, always use the same boot image from your firmware, a lot of confusion comes to the fact, that when you uses TWRP.img or Magisk.img they aren't boot images, but they are; A/B partition scheme doesn't use some individual partitions anymore, as /recovery, thus is extremely important to patch your boot image, where the recovery, kernel and other components now lives.

So, in other words, your method is this (correct me if I'm wrong):

1. Download TWRP zip file and copy it to your device (internal or external storage)
2. Download TWRP img file and and store it, on the folder where you have adb and fastboot files, on your PC
3. Open a cmd line and execute these commands (beeing on that folder, of course):
   
   adb devices (to make sure your device is detected)
   adb reboot bootloader (to reboot into fastboot mode)
   fastboot erase boot
   fastboot flash boot twrp-3.3.1-2-unofficial-laurel_sprout.img
   fastboot reboot (NOTE : Before hitting "Enter", long press Vol + on your device until you see the Android One logo. By doing this your device will be forced to boot into Recovery and not into System)​
4. Flash stock boot.img that matches your current build using TWRP install Image feature, into boot partition
5. Install the TWRP zip (always install the latest build available)
6. Reboot to System

Is that it?

If it is, the only downside I see is that, when a new version comes out (through OTA for example), you'll first need to get your hands on a stock boot.img that matches the new build.

Right?

Cheers!

As someone who just wants to root his phone with TWRP and few magisk modules, and not miss out on OTAs, seeing these many methods is so confusing and overwhelming ?

 

[RJ-]

After flashing recovery from pc..then go for fastboot reboot from minimal adb and " volume+ key" i saw error in my phone "no command"

 

[bibekmufc]

Use the method Typhus explained, it's more simple in the long run; there will be no need to manually flash stock boot image afterwards, since Magisk will have done a proper backup, thus, you will only need to use 'restore image' feature inside Magisk Manager; When taking an OTA, make sure to read the complete Magisk documentation before proceeding:

Thank you! I will do that. But one more thing I'd like to ask. Do you know where I could find the boot image for 10.3.8.0.PFQMIXM? I checked git for dumps, but I couldn't find the boot image for this one.

 

[bibekmufc]

Sure, read the OP; Typhus has linked a couple of boot images, including 10.3.8.0 PFQMIXM.

Sick! Thank you very much, sir!

What about flashing this on an already rooted phone with Magisk modules and the previously available TWRP by mauronofrio? Any complicated procedures? Is slot changing etc still necessary?

In that case, obviously, simply flash the new TWRP zip.

The install method I've explained is for everyone who never had TWRP, or Magisk patched boot, installed on the device.

Just flash the zip in twrp that you have.
That's what I did and it worked no problem on pe ROM

I did as you said but it says 'NOTE: You are now unrooted!'. Do I need to flash Magisk again?

Yes, that's right.
