Hi there guys, i had redmi 3s prime. i guess have to unlock bootloader and root to flash custom rom. right? so if anything **** happens and if want to take it to service center (or if not i just want to), can i revert back to original state with MIUI stock os (which can receive official miui ota updates) and eligible for any warranty as same as original handset?
Of course.You can do it,use unbricking method or fastboot mode flash using miflash app.
Yes, ofcourse...you can backup using TWRP and restore everything ...
and secondary you can use MI Flash to flash fastboot rom and bring back everything to normal
Of course you can. Just do what you did when flashing custom ROM.
I have a Samsung Galaxy J5 2015, SM-J500F. I successfully flashed TWRP and installed Lineage 14 over my stock Android 6 (or 5, I don't remember) over 2 years ago. I thought that I could move to Lineage 15.1 as it's already 2019 and the OS is stable right now.
I successfully flashed TWRP 3.2.1 on my device using Odin (I unchecked auto reboot option since I read that it causes some troubles). However, when I try to boot into TWRP recovery mode (Vol UP + home + power), the Samsung logo appears but after a while, it disappears and nothing happens, there's just black screen. When I take out the battery and put it back in and power the device on, as usual, I can still boot into Lineage 14. In developer options, I checked Advanced Restart and USB Debugging.
Anyone had a similar issue?

Wrong bootloader and modem.
You have lollipop (android 5) you need marshmallow (android 6)

Oh, now I remember... When I was flashing Lineage 14 over 2 yrs ago, for some reason (maybe I understood smth wrong on xda) I had to downgrade from stock Android 6 to 5 in order to be able to do it. Now, Lineage 15.1 requires firmware of Android >= 6.0 but it cannot be provided by custom ROM, only by stock ROM upgrade. Does that mean that I have to go back to stock 6.0 ROM in order to upgrade the firmware and then flash Lineage 15.1?
Btw I read the thread you linked and can I ask what does exactly mean "to flash a marshmallow bootloader"? Do you mean some specific TWRP version?

Instead of flashing the whole stock rom you just need the bootloader and modem which is required by the rom to boot up. Its not twrp or anything its just how the device boots. Just flash the bootloader and modem from the instructions on that thread then boot back to twrp and flash the rom and gapps again
Good day i have a problem with my mi 9t. I have installed the miui 11 eu version on my phone and i was using it for a few weeks. I have decided i want to go back to miui 10 global but when i go to flash the rom with mi flash tool i get antiroll back error as seen in the image on this post. I have tried to install via TWRP chinese recovery but the phone shows the logo for a few seconds and then goes straight to the TWRP recovery automatically. I tried installing havoc os pie still same problem. I was reading up about the anitroll back that the miui eu has and i think that the phone is soft bricked because i tried flashing via twrp with anitroll back on my phone. I did the anitroll back test to get the index and i have a antiroll back index of 1. If anyone can help me with this problem or have the solution please give me some help. Thank You
I am able to get into twrp recovery but any rom i flash just reboots back to twrp recovery
Ok I fixed it I just flashed back the miui 11 eu I was using before and it boots up but now I want to flash the new miui 11 global but I'm afraid it may brick again. Only one way to find out.
Have a same problem, what version eu rom work in your MI9T
Android 10 downgrade.

and reboot using fastboot command itself
it will go straight to twrp recovery mode.
just give wipe data function which is default...
then flash the android 9 ozip , after that dont reboot to system
go back and flash the stock recovery from android 9 which is attached with this post and then reboot..
now you are back to android 9.
this method is working for me ..
after sitting many hours with stucked twrp recovery i just flashed the stock recovery and it get in to the device
Please read whats the state of my realme x2 pro so that you can understand what I have done.
I purchased the realme x2 pro 12gb/256 in the uk , it is shipped with the android 9, there was some OTA update and I had done that and the phone was still in Android 9 with some bugs fixed. Again I recheked the software update for Realme ui update but nothing was found.
So I headed to realme uk website and downloaded the Android 10 realme ui ozip , copied to the phone and updated. Now the phone was in android 10 with realme ui.
The software update is good but I don’t like the finger print animation and also I noticed a sight battery drain,but I am not sure if it was same like in android 9 , I mean the batter life. So decided to go back android 9 . so after so many tries and all finally downgraded to android 9 with the bootloader locked and widevine to L1 and google pay working. Now all stock and all finger print this and that working !!!
Downgrade procudure :-
Backup All the things that are required, All will be wiped.
1.First thing is to unlock the bootloader in Android 10 because of I updated to android 10.
Follow this link below , download the deep testing apk and unlock the bootloader.
https://c.realme.com/in/post-details/1253651898825703424
2.Make sure you all had the proper working adb drivers in pc and android bootloader drivers,
After completing the 1st step , Download the twrp from the link below:
I downloaded the one in this name TWRP 3.3.1-13 Unofficial by mauronofrio
https://forum.xda-developers.com/re...covery-unofficial-twrp-realme-x2-pro-t3997879.
How to flash twrp in realme x2 pro follow this guide below:
https://forum.xda-developers.com/realme-x2-pro/how-to/guide-unlocking-bootloader-to-getting-t4010189
follow the procedure above and until flashing recovery and don’t flash vbmeta and all
3. Download the Android 9 firmware with stock recovery , this was the lastest one I dowloaded from xda
(https://forum.xda-developers.com/realme-x2-pro/how-to/rmx1931ex11a-10-available-t4059607)
4.Downloading stock recovery :
https://sourceforge.net/projects/rmx1931ex-stock-files/files/RMX1931EX_11_A06_GLOBAL.zip/download
download this zip file and use only the recovery.img after unzip , this is the only file we need from this folder
Second part:
I Assume the bootloader is unlocked , the device wiped and rebooted to os , copy the ozip in the and stock recovery in internal memory, we might need to use this for later.
now flash the twrp using the guide above and reboot to twrp recovery.
In twrp install the android 9 ozip that we downloaded in the phone memory , after it flashed don’t reboot.just go back and flash the (recovery.img) from twrp itself and choose the path recovery and flash , after that the phone will reboot and it will go to stock recovery. Then give a wipe in the stock recovery and reboot. Now you are back to stock android 9.
Now we are in android 9 with the unlocked bootloader. That’s all.
For those who needs to lock the bootloader read the information below
Check the stock recovery version number ( if it shows rooted near the version number) if it says rooted don’t relock the bootloader. From the phone just run stock ozip again and let it boot in to os, after that again check the stock recovery if rooted string is gone. If it is gone now you are good to lock the bootloader.
Because with unlocked bootloader the google pay is not working so for me locking the bootloder is important for me , also I checked in the device info that widevine is change back to L1.

Or why downgrade to 9?

- More battery long lasting on A9, perhaps more services are running in A10 rising power consumption or not well updated.
- In early versions of A10 call recording was capped due privacy rights. With the last update C.26 I can record calls but not tag the records accesing to the contacts list.
- Also in the last C.26 update of A10, you can take RAW photos in 'expert mode'.

Thank you for the info.
Just upgraded, first there was an odd connectivity issue, every GPS fix loss, deactivated mobile and WiIfi for 5 seconds
After turning Smart power savings mode off and on, the issue disappeared.
About raw mode: Odd raw mode that does not save in 64 MPix

Thanks for ur help But is there a way to get a stock recovery for Chinese version ?
Are you sure that we don't have to flash vbmeta.img.because somewhere i have read that if i don't flash vbmeta my phone will be dead

It seems I don't find out how to start a new post! That's why I answer here. I have a Xiaomi Redmi Note 8T. Now I would like to install Lineage. Therfor I have to unlock the bootloader. Despite doing it all like it is written, the Mi Unlock Tool always spits out an error, see screenshot attached. It says nothing about 30 days wait, it simply doesn't work! Any ideas someone?
