Question Downgrading firmware - Xiaomi Poco X3 Pro

I now have a phone that had 12.5.3 installed from the start.
Is it safe to install the 12.0.4.0 firmware on this phone?

Yes, do it carefully, following all the steps. If it is running stock MiUi also read about Xiaomi's fallback protection or else your phone may get bricked.

Sprint Samsung Galaxy S3 - I was on Gummy-M1.2-03-10-14-NIGHTLY-d2lte with pa_gapps-stock-4.4.2-20140207-signed.
I was on I upgraded the other day by flashing:
Furnace kernel 1.0.8-aosp_m8
Gummy-M2.3-07-15-14-NIGHTLY-d2lte
pa_gapps-stock-4.4.2-20140608-signed
Only then did I find out that my 64GB external SD card is read-only and basically worthless in Android V4.4.4, (thanks a BUNCH, Google!!) (NOT!).
What is preventing people from being successful in downgrading back to 4.4.2? If re-flashing the old stuff isn't a good answer, do you know if a simple restore of my Nandroid backup would take it back?
What a pain!
Thanks!
i would like to know this aswel ,is it possible to go back to 4.4.2 from 4.4.4 ?

Finally i was also able to downgrade to 4.4.2. Always when i tried to flash 4.4.2 as usual via fastboot i got stuck at the Bootloader unlocked Screen. Magically after flashing CM i was finanly able to downgrade to a working 4.4.2. Do not really know what happend and if it is somehow related. I'll try to reproduce it later..
I was able to downgrade from stock 4.4.4 to 4.4.2 but not any lower.

Ok. No need to worry. Here is the next step. Download your ROM from http://www.sammobile.com/firmwares/database/SM-N915F/
There you will have instructions on installing and then you will be able to update your base-band manually. This should fix your problem! Let me know how it went!

121
u can unroot it in super su . but u don't need to do it .. just downgrade to very first ROM like B120 or B121 I actually tried and flashed B120 and I have feeling that phone is much faster ! believe or not because B120 and B121 IS official but anything else up is unofficial
(for L09)
I'll try to flash my L10 today and replay back

Looking for Official Support [Mate 9 Lite - BLL-L23]

Hey, everyone,
I just bought a new Mate 9 Lite [BLL-L23] and would like some help with how to make it my own. I am familiar with other devices - but, not the BLL-L23.
I am very appreciative, my friends! Here's what I'd like to know:
1. Does anyone know when we'll get Android Oreo (or, at the least, Android Nougat)?
-- I am currently running 6.0; EMUI 4.1.
2. Is there an official support forum for the BLL-L23?
3. Does anyone know how to root the BLL-L23 using Magisk or Chainfire (which is better)?
4. Is there a recent TWRP recovery available?
5. What else should I do to take full advantage of my device?
THANK YOU VERY MUCH FOR EVERYTHING, EVERYONE!

I am currently downloading the latest full firmware, and I know it's not a problem to install it - but, when I check the Firmware Status, it says that the firmware is not approved for installation. Is there still a way to install it? What does this mean? Thank you very much, PalakMi ?

Mate 9 Lite is a rebranded H6x, OpenKirin's TWRP works fine. You can also use Firmware Finder for updating. Magisk works fine too. I think all Custom ROMs on this forum should work. I'm planning to flash RROS but I'm waiting for some bugfixes.
The only thing I suggest you is, if you want to update your Stock ROM, you MUST flash the right ROM for your device.

FF update may not work all the time. But for twrp, check and you should get the openkirin twrp from 6X thread working.

Does anyone have a stock boot.img for the FRD-L14?

I stupidly flashed the wrong boot.img and i'm stuck in a boot loop. Anyone have or know where to find the right one?

I don't think you can still check sadly...
Maybe the boot.img doesn't change through the firmwares but i'm not sure about this...
I would suggest you to do a rollback to get to the stock firmware
But wait, maybe a more competent person will have a better solution for you.
By curiosity were on Android 6.0 or 7.0?

Android 7.0. Will doing a rollback wipe data?
Yes, doing a rollback will wipe all your data...
I guess your phone was up to date?

It was emui 5.0 and Android 7.0, so yes.

Sadly, I expected it a bit...
What you need to do is to find the latest firmware for your phone (supposingly your phone was up to date) and then extract the boot.img with HuaweiUpdateExtractor.
Otherwise you need to do a rollback and get back to stock firmware...
Also you can wait for someone with better acknowledge than me to help you.
Good luck!

Hi:
This is an old post, but just curious about the firmwares for frd-l14 at romfirmware.com. Is it a trustworthy site? Seems a little sketchy. Wanted to make sure before I download anything.
Thanks
