No yaar, not having that issue too
I use Reliance Jio in Sim 1 and Airtel in Sim 2
As i am in MIUI chinese beta, after testing any recent rom, i will have to restore to MIUI so i flash via fastboot everytime
As latest MIUI roms are encrypted always revert back to 6.8.11 5.1.1 version i have via fastboot, flash twrp then flash any rom

Does it matter if the ROM is encrupted?
I mean i am on locked bootload, china dev 6.9.9
I want to move to global stable 8.0.1 .. so fastboot rom via EDL should work fine, isnt it?
How do I unlock my bootloader on cm14? You have mentioned in second step to make sure the bootloader is unlocked before flashing MIUI 6.7.21 but MiFlashUnlock cannot unlock the bootloader.

for that u need just 1 modem file to flash.. and everything is fine.
Or just backup every partition with alka before flashing cm14 and afterward restore it (ignore firmware) to have your previous rom back with the data and everything and no flashing required. People just overcomplicate things. I've done this with every single combination of roms and bootloaders ... And it always works.
Miui lp, miui mm,cm13, cm14, aosp, you name it

well i can confirm this works. just switched back ti 8.0.1 from dev 6.9.9. (i.e., MM to L) and all is ok.
no need for an unlocked bootloader

Yep
For AOSP stock leaked rom
we cant unlock bootloader sometimes, the only way to revert back is fastboot flash via edl
very handy
Any method for unofficially unlocked bootloader here? Thank you.

Hello all.
Im a little bit confused about the bootloaders and their marriage with their standard ROMS.
I am in MM B13 in a 2017 unlocked using bkores toolkit and would like to check Nougat ROMS.
What happens if, from this MM unlocked state I flash an official Nougat for 2017? Is safe? Could I eventually flash a TWR to return to my "original and safe" state? Could I flash back an "official" MM B13 for example?
I am guessing that maintaining the phone in the unclocked area is safer than recover the lock. Is this true?
There is a "Universal bootloader" for Nougat ROMS. How "Universal" is this bootloader? Does this bootloader runs in MM?.
If I apply a SD "complete" update (being MM B13 or Nougat), do I relock the phone's bootloader?
If I upgrade fro MM to N, do I lost the possibility of flashing a custom recovery? (TWRP). This is a non go for me, as you cannot go back...
Hope you can answer these questions
Regards

Forget about the bootloader thing for now - it should be universal for MM and N. Not gonna relock itself.
-If you want to go back from a custom ROM (you'd have the A2017X_Universal_Bootloader, the ROM and the modem that goes with your device, plus a version of TWRP installed) what you would do, at least in A2017Gs and Us, is to flash a stock recovery zip to get the stock recovery. After that you reboot to the recovery, and you'll get to MiFavor's recovery. from there you would flash an official zip and every partition would be overwritten with what's on the zip. I suspect that ZTE packs every update with everything in it so that you can roll back, say, from Nougat to Marshmallow officialy, without messing everything up.
OR you can use MiFlash to reflash everything with a computer. Just download the full EDL file from 4PDA and flash, you'll get full stock (but still unlocked BL anyways)
So yeah, you CAN get back to full stock anytime.
-Don't just try to relock the bootloader. AFAIK if you relock it and you have root or TWRP or somesuch you can brick your device. I'd advise against trying to do that, but if you must, look at a guide or two at least.
-Yeah, pretty universal. I wonder why you'd want a custom MM ROM though. if you want to go back to stock MM it will get replaced by another one anyways.
-Already addressed, no
-I don't know the exact case with A2017 phones, but you said you cannot go back? You can. If you're on official N and want to roll back all you have to do is put an official MM zip on your SD or internal storage and go to Updates.
That being said, you still can use axon7tool on Nougat if it supports A2017 phones, which it should. You use EDL mode to flash the recovery. it is what I always do on my A2017G.

So...
i) Bootloader unlocked is safer than locked and problems can arise if i try to relock.
ii) I can flash from SD every official thing published by ZTE if I flash previously ZTE recovery. (bootloader still unlocked). From that startpoint, I could reflash TWRP using fastboot or EDL. Once in TWRP, every ROM is flashable if partition compatible...
iii) I can stay with my unlocked bootloader with every MM or N. Important things are the modem and other stuff. N is not much different from MM and I like Xposed....
Big, big THANK YOU!!!!

Hello guys i can't back to stock global rom with mi flash tools please someone help me how to fix this error
Me too Mi 9T
I have the same problem here, anyone managed to solve the problem?
I'm same
I also had this problem after flashing android 10 based custom rom via twrp and flashing stock rom back via mi flash tool. It was solved by below for me:
- First flash back android 9 based custom rom by twrp. Boot for first time. In my case, it was bootloop.
- Then, enter fastboot and flash stock android 9 rom with this mi flash tool beta. Find in this link. (mirom.ezbox.idv.tw/en/phone/davinci/)
- It was success for me.
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
I have recently flashed my Asus zenfone max pro M1 to evolution os 4.5 and it has a lot of bugs like wifi not coonecting, random screen off and does not turn back on until I restart, hotspot not switching from setting menu(I can only do it via quick settings.
So I want to switch back to default stock rom. I have twrp and magisk and unlocked bootloader unofficially.
All I can find is a old thread with android pie and I I have unlocked bootloader so I will not get ota to go to android 10.
So how can I revert back to stock android 10 stable?
