Hi,

First of all thanks for the thread :)

Just a quick question; After some trouble flashing DEV rom (had to do it firstly via MI FLASH TOOL); Then I flashed the this threads DEV ROM but there is still all Chinese app bloat-ware and no play store even after a factory reset (still waiting for unlocking code to flash TWRP)

Can you please validate how can I get rid of all of this and have a fresh install( since if I manually install google play store MIUI Store will autoupdate the installed apps changing names to the chinese ones)

Thanks
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Perfectdevil:
Just download (( system app removal )) from play store

Actually, no. I figured it out - after flashing a rom with TWRP, you must flash "cracked" boot.img for THAT particular rom. So if for example you are flashing 6.3.24. you must flash cracked boot.img of 6.3.24. rom right after flashing the rom. Here you can download this toolkit, in the "cracked boot.img" section you can find cracked boot images for specific roms. :good:

EDIT: here is the link for the toolkit if you don't have a miui account

[Xiaomi Redmi Note 3 Guides, News, & Discussion] 1emrys1:
You need to do your homework before acting smart. Global developer rom of all phones that have been released globally is being released. These roms are not released every week like China developer but they are certainly updated. You say that 4 months since any of the phones got global developer! Really? Here are some screenshots of Redmi 2 and Redmi Note. I could give you more.

Redmi Note 3 has recently been released outside of China and has got global rom. It will soon get global developer like every other xiaomi phone. And to reiterate my point, you should inform your readers that the developer rom you're providing is China developer. Don't be extra smart.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] :
[MENTION=7367577]jazzzu4ia[/MENTION]

It does no work for me either. I'll explain what to do:

1. relax :P

2. download this and extract it somewhere easily accessible

3. edt file "boot.bat": right click->edit ** delete last line (reboot fastboot) ** ->save file

4. read "readme.txt" and follow all the steps

This procedure is for flashing chinese developer rom 6.3.17. You could also apply it for flashing 6.3.24. but you need cracked boot.img of 6.3.24 rom and rename it to boot_1.img for it to work with boot.bat executable

Hi everyone. I bought a Xiaomi redmi Note 3 pro from gearbest. It comes with a locked bootloader but with a ROM cooked by them with version 7.1.99.99. The weird part is that I can't flash an official rom, neither by fastboot nor the updater app. Grrrr. Can someone give me an idea of what I can do, besides applying for the bootloader unlock which I already done... Thanks

Guys you don't need TWRP to get root. Just unlock, and enable root through the security app
[Xiaomi Redmi Note 3 Guides, News, & Discussion] _ossie_:
That is correct on the DEV ROMs (not sure about stable), but native root is not as functional as e.g. SuperSU.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] sanjib734:
U can always install Super Su from play store after getting native root, it works perfectly.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] _ossie_:
Super SU from Play Store will not work on its own. You need to flash the binary using a Custom Recovery such as TWRP.

You also can't write to /system with the native root, which sucks. Still good enough for my needs though

Hi,

First of all sorry for the stupid question! In some forum I have read that it is not possible flash the global stable Rom from the update app but here I read the contrary. So I'm just asking the confirmation. I have the China stable 7.2.1.0 and my goal is to flash the official global stable Rom 7.1.8.0. My phone had the bootloader locked. So please can you confirm that I can download the global Rom, save it into the internal memory, run the update from the app and wait for the reboot? Should I reset the phone to the factory before or is not necessary? Thanks in advance for your answers.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Rajdip:

so now heres the thing i got the 7.2.2.0 update (gloabal)

so i figured lets just try unlocking bootloader on this rom (got permission) and surprisingly it worked

now i want to flash twrp but cannot find cracked boot.img for miui 7.2.2.0

any ideas
[Xiaomi Redmi Note 3 Guides, News, & Discussion] Rajdip:
you need to flash modded boot.img for twrp or you will get bootloop, theres no modded boot.img for 7.2.2.0, but can you check whether theres a boot.img file inside the recovery zip? I dont think theres a fastboot file for 7.2.2.0, need the original boot.img from 7.2.2.0 for creating the modded file, if you can provide it to me, I can mod it for you :)

---------- Post added at 11:59 AM ---------- Previous post was at 11:41 AM ----------

@Perfectdevil add this to OP, flashing full fastboot/recovery roms through twrp will relock bootloader and the device will get hardbricked, for updating rom use OTAs. For flashing full recovery rom delete the "firmware-update" folder from rom zip file, and then flash the rom and then flash modded boot.img specific for that miui version :) Also you can delete the firmware-update folder from OTA zip files just to be on safer side
[Xiaomi Redmi Note 3 Guides, News, & Discussion] _Latino2_:

So, please tell me is it east to hardbrick your redmi note 3 or is it just soft brick and flashing stock rom via fastboot ROM will restore it to normal conditions. On my previous devices moto g and Oneplus One hardbrick was extremely difficult to do.
[Xiaomi Redmi Note 3 Guides, News, & Discussion] _Latino2_:
If you don't delete that folder before you flash your bootloader will lock again. Fastboot won't do any good. I had to disassemble the phone and connected two pins to be able to enter edl mode. From there I was able to flash latest China developer rom with miflash. Though but it was not my first time opening a MI so I was confident. If you need I'll try to find the post I followed to unbrick the device
