8.7.5 Firmware over 9.5.17

Can I flash the 9.5.17 firmware over the 8.7.5 one? Is it safe?

Both are anti 3 firmware!
So safe to do so, but why the need?
I know that the stable firmware is slightly newer than beta version.

Yes, both are anti 3.

And from 8.8.2 global beta to 9.5.19 global stable?

Check 8.8.2 anti in fastboot mode with the command fastboot getvar anti. If it says 4, you can go to 9.5.19.0.

I'm using 9.5.19 atm and would like to test MIUI10 without loosing the option to go back to 9.
Anyone knows if 8.8.2 beta is anti-4?

you already in ARB4 so you can try latest miui 10 as itll be ARB4 too. just dont flash miui 10 8.7.5 or miui (9.5) 9.5.17.0
to go back to 9.5 just flash 9.5.19

My bootloader is locked and I have the stock recovery. I can install both roms using the update app and choosing the ROM file?

Downgrade to an old xiaomi.eu rom without triggering Rollback Protection

Dears,
I have a Xiaomi Redmi Note 5 (Global) with
MIUI Global 9.5.19.0 on Android 8.1
--> so the Rollback Protection is ENABLED
and I would like to flash a xiaomi.eu ROM. Specifically I would like to downgrade the device to version MIUI 9.3 8.3.1 based on Android 7.1.
Is it safe? Can I proceed without triggering the rollback Protection?
Thanks in advance

update pie firmware without arb4

hi , i wanna ask about update whyred firmware .
currently my whyred have oreo based firmware with arb 3 , usualy im using firmwareless method to flash custom rom.
and since lattest aosip and AEX rom need original firmware my old method use firmwareless its no use and phone become bootloop.
my questions :
1. does we have another way to update whyred pie firmware without affect to arb ( prevent arb 4 )??
2. if already arb4 can we still flash both EU miui rom and global china rom ( using firmwareless method ) ??

up

1. No
2. Yes, look for arb4 thread (there are 2) on how to flash twrp back in arb4 condition
P.s - you can downgrade to any global miui rom which have arb4 (oreo 9.5.19 - pie 10.3.1) and you can use custom rom with arb4 condition

first you need to know what antirollback you have. you cannot downgrade from ARB4 to ARB3 if you on ARB4 then research if the last miui 9 its also ARB4 if both are then just flash using miflash
check here
https://piunikaweb.com/2019/05/13/m...it-super-easy-to-get-xiaomi-phones-arb-value/
then using fastboot rom and mi flash.
according to this.. (9.5.19 update enables Anti Rollback Protection, ARB = 4 ) so just research and be sure it does

I'am still on MIUI 12.5 the way it came delivered.

Use stock miui12 rom with mi flash for no risk, mi flash errors can be fix easily....search google for accurate resuls
Then flash your desired custom Rom
