THIS GUIDE IS FOR ALL MIUI BASED ROMS WHETHER IT IS OFFICIAL, UNOFFICIAL(Xiaomi.eu,sphinx) OR MODDED(smiui).This is for the people who unlocked bootloader through the unofficial way.
http://forum.xda-developers.com/redmi-note-3/how-to/unlock-bootloader-waiting-permission-t3349886
People with officially unlocked bootloader can also try just to be on safer side...nothing to lose right?
Many people after unlocking their bootloaders flashed miui recovery/fastboot roms through twrp/miflash and got their device hardbricked with locked bootloader, which is a pretty messed up situtation, (follow this guide if you are a victim
http://en.miui.com/thread-245347-1-1.html
) and the only way to unbrick from that state is test-point method which voids warranty of course. Others who flashed fastboot roms with default recovery using miflash ends up with locked bootloader too, so I'm gonna share steps by which you can flash full recovery/fastboot roms and not get harbricked/locked bootloader:-
1) First let me tell you why it happens, every recovery rom zip file has a firmware-update folder containing a emmc_appsboot.mbn file, that file relocks bootloader everytime a full rom recovery rom is flashed, fastboot roms also have the same emmc_appsboot.mbn file.
2) To flash recovery roms through twrp, delete the emmc_appsboot.mbn file from the firmware_update folder inside the rom zip file, and then flash rom. Winrar works best, open the recovery zip file with winrar and open firmware-update folder and right click on the emmc_appsboot file and select delete, wait for it to complete(takes some time). For fastboot roms extract the download fastboot file and delete the file emmc_appsboot.mbn file from the images folder. Also in order to keep your desired recovery like TWRP intact, delete the recovery.img file. Edit :- Tested it on my Redmi note 3 pro, deleting only the emmc_appsboot.mbn file works, no need of deleting entire firmware-update folder.
3) To update roms, first download OTA through updater app (or download it from pc) and then open the OTA zip file (located inside downloaded roms folder) and delete emmc_appsboot.mbn file inside the firmware-update folder and then flash through twrp. OTA's can relock bootloader and hardbrick(as it happened in Mi4c).Can't flash OTA due to build fingerprint error? Follow this guide
http://en.miui.com/thread-262947-1-1.html
4) After flashing rom through twrp, flash modified boot.img specific for that miui version, or else you will get bootloop. Guide to make modified boot.img http://forum.xda-developers.com/redmi-note-3/how-to/creating-modified-boot-img-enabling-adb-t3359916
Original Boot.img is located inside recovery rom zip.For those who dont want to do it manually, link for downloading modified boot.img
http://miuidroid.com/rn3/boot_images/
(credits to magdag)
It is required to flash modified boot.img even if you updated through OTA.
P.S:- I've tested all this using my Redmi note 3 pro, should work on other devices too. Any suggestions for improving the guide is welcome.
If I helped pressing thanks won't cost you a thing.:good:
Can you update or post the modded boot image for latest SD 7.2.3.0 Stable global rom?
I have 7.1.8. global rom with officially unloced botloader and TWRP. If I want to install the update I just download the OTA from the updater app in my phone, then remove the emmc_appsboot.mbn and flash. Do I need to flash a modified boot image after that?

img file can flashed via TWRP, when you select install option on TWRP , look for "install image" option on right bottom part of screen, now select the modified img and then select boot and then flash.

Yeah you can use china dev rom for unlocking bootloader, and after that to upgrade to global 7.2.3.0 you need a full recovery rom, OTA wont work, also WHENEVER YOU DOWNLOAD A OTA/ROM OPEN IT WITH WINRAR, OPEN THE FIRMWARE-UPDATE FOLDER AND DELETE THE emmc_appsboot.mbn file or else you will hardbrick your device and the only wasy from recovering from it is by opening your phone

Hi , can you make sure again that China dev ROM will work in place of stable 7.1.8.0 without any problem ?
Also 7.2.3.0 which I've is full ROM i think it's "miui_HMNote3ProGlobal_V7.2.3.0.LHOMIDA_74136dde89_5.1.zip" and it is 0.99 GB in size.
So after unlocking bootloader , i can normally boot into current china dev ROM and directly upgrade to 7.2.3.0 through updater app with just emmc_appsboot.mbn deleted from it ?
I guess there is no need to delete boot.img as i still haven't flashed the twrp and root yet and will flash both of files after upgrading to 7.2.3.0 .
Plz tell if my steps are correct or not ?

What about you use the miui global 7.2.3.0 directly for unlocking bootloader the unofficial way? after that you can flash TWRP if you want, and you cant update using updater app, you have to update directly from TWRP.

Well to do that i have to download again the GB of flashboot rom of miui global 7.2.3.0 and i really have painful slow internet so thought of first unlocking bootloader and then later upgrade through Recovery zip file.
What do you suggest for best way as i just don't want to f**k up my device..
So if updater app can't flash the Official MIUI roms even with unlocked bootloader then what's the point of recovery ROM of different types such as global stable,beta china stable beta if you want to switch ROM's ?
Why in redmi note 3 there are so hurdles to switch /downgrade/upgrade ROM after unlocking bootloader ? I have done all flashing stuff on some other android phones too but there was never a risk for relock of bootloader and overwrite of custom recovery while flashing ROMS ..so why all this hurdles in Redmi Note 3 as it doesn't make sense to unlock bootloader after each and every upgrade /downgrade of ROM's or it is only due to the fact that it has been unlocked through unofficial way ?

This is what xiaomi made of themselves, every move is f*****g hassle right now. I understand the problem of slow internet. You have unlocked bootloader right? why dont you just leave MIUI and install the AOSP rom. no more hassle no bricks.
To be honest I'm a noob ,but messing around with my phone I rooted my phone accidentally with kingroot n kingoroot and later unrooted clearing su and also busybox .recently that is on 1 October HTC released an OTA of Android 6.0.1 for Indian customers but when I downloaded and started installing it, it fluently went till 25% but then it completely stopped and rolled back to normal state , I guess this is because I rooted and hence few system files might have been modified
My questions
1) can I remove the modified files so that I can install the OTA
2) how to install stock recovery version (5.0.2)from htcden because the kernel file is not in zip format ,and please mention step by step procedure to do so if there is any
3)if Incase I re install the stock recovery will I be able to receive OTA again ?
NOTE :BOOTLOADER IS LOCKED AND S_ON .SO I DONT KNOW HOW TO INSTALL STOCK IMAGE
Build Fingerprint of now htc asia wwe :5.0.2
Kernel version : 3.10.61
Build number 1.90.707.3.

Hey guys!
I recently read many Questions About downgrading the Galaxy S8 to 7.0/8.0 after we got the 5x Bootloader.
Well many of you say NO but What many of you forgot is that there is a way to Downgrade your phone.
I already had that Problem with my S6 back in 2016, where I wanted to Downgrade it to 5.1. All you Need for a Downgrade is a Combination File.
Combination files are basically used for testing purposes in the Samsung devices. These files are there to make sure that the functionality of your device is error-free, before making its final release. These files are created by Samsung company and are found in only their devices.
Combination ROM Advantages:
Its help you to repair imie number in some models like S8/S8 plus S7/S7 Edge S6/S6 Edge…
Its very useful in bypass samsung account in too many models.
Its very useful in bypass Google account in too many models.
Its very useful for downgrade in some models.
Its help you to enable usb debugging.
its help to remove any security FRP / Reactivation Lock from Samsung like 2016-2019
You can find Combination Files for Galaxy S8 devices here:
G950U with latest Bootloader: http://www.mediafire.com/file/j8xi2n73zhh37q1/COMBINATION_FA70_G950USQU5ARG4.zip
G950F (currently only for 4x Bootloader): http://www.mediafire.com/file/c37zq...QB19841686_REV00_user_mid_noship.tar.rar/file
Here is a Video of Downgrading a Galaxy S6 Edge with Combination File : https://www.youtube.com/watch?v=dOKJcHU1pXM Should work with S8 too
Hello, nice tutorial!
Want to ask:
"Combination files are basically used for testing purposes in the Samsung devices. These files are there to make sure that the functionality of your device is error-free, before making its final release. These files are created by Samsung company and are found in only their devices. "
So only Samsung releases these files to public? or are leaked?
I`m asking to check if I should wait or not, I had V4 bootloader but recently by accident with the latest update I got V5

I would recommend you to wait till the latest Combination File gets public for the G950F/G955F. They do work very good and are also stable. Usually I think Samsung does not public These files online but they get leaked very often. I used the Combination File to Downgrade my S6 from 7.0 with Bootloader 6 to 5.1.1 with Bootloader 2.
Im sorry but I can only explain the function of a Combination Rom along with the Galaxy S6..
Once Cthe latest Combination File is available, do this:
1. Download your Nougat/Oreo Firmware you want to install
2. Download Combination File with the latest Bootloader Version
3. Downlad 7zip, since you Need to edit the firmware you want to install
3b) Extract the firmware you want to install to a new Folder
3c) Delete all files except for boot.img, cache.img, recovery.img and system.img
3d) Open 7zip from your Start Menu and locate the firmware Folder
3e) Mark the remaining files and press the green "Add" Button at the upper left corner and create a tar (Odin Flashable) file
4)Download Odin
5) First uncheck Auto-Reboot
6) Now first Flash the Combination File
7) Afterwards go directly again in Download Mode and Flash the tar- firmware File
8) Reboot your phone and do a wipe
9) Congrats! You now have Stock 7.0/8.0 Back!
Notes: Fingerprintscanner wont work, because it is a part of cm.bin, OTA Updates wont work as well, Dont worry if you see a green text next to the Phone logo while starting it. Thats normal and not an error.
Backup your files before you do that!
I hope it helped you

Yes, many thanks for response!
I guess I will wait until I get the combination of files, but until then I want to switch CSC, found a solution to use THAI sim card, but not sure, if everything goes ok, I guess the new OTA update will be the latest from THAI, there are no changes to get bricked by this method right? ( I will be able to get back to the ROM stock that I have now? )

Hi, ok but it means that i cannot use fingerprint or ota update anymore or after dowgrade could i install full stock firmware with odin and recovery functionalities?
Will this trip Knox?
Any idea if I can downgrade from pie on a S8+ on bootloader 6?
I've tried this method on my S7 edge but I've stucked on step - deleting files.
After extracting the firmware I get 5 files- Ap, Bl ect.
When i extract the AP file (previously deleting "md5" from the name, and becoming rar file) there are only 3 new files (nothing for delete if i remembering correctly)
Files i need to delete are on other files from extracted firmware.
At the end I finished on unsuccessful flash.
I want to go back to nougat on my S8+ (955f), but i dont want to take risks, so I did flashing on old device with corect firmware.
I'm really mad at Samsung. Battery life become horrible at pie. Thats why I want to go back to nougat or at least oreo.
I will post some videos after day or two how is possible to downgrade android version on some Samsung devices with higher bootloader version. These methods didn't worked for me but may be they will encourage some of you to make possible the downgrade.
As I promised:
1. Interesting way to downgrade Samsung Device (J series) when touchscreen does not working:
https://www.youtube.com/watch?v=SmfgxoUhflA&feature=emb_title
2. Second method:
https://www.youtube.com/watch?v=ZKg1DC4ul_g&feature=emb_title
As I remember oreo and nougat have pro mode on video recording and faster charging speed. I hope someone to explain is it possible to downgrade S8 and whats are the steps with this method.
so if i want to downgrade to firmware with bootloader v4 but my phone has now v6, will i download combination file with bootloader 6 or 4? I didn't get that part, sorry. i have s8+
edit: ok, 4 didn't work, so i guess need to get 6
Does anyone know the password for the linked Combination file?
Thanks for this thread.
I want to downgrade from Oreo to nougat too, I'm on "U1" security patch, but I don't understand the order of bootloader version... Can you try to explained how to ?
I found this if it can help : https://combinationfirmware.com/combination-samsung-galaxy-s8/

Since you are on bootloader version 1, you don't need the combination files. If you were past version 2 they would be needed.
Once you update to a new bootloader you can't go back to software on the older bootloader without the combination files.

If you have an Exynos version, maybe ask around on that thread.
If you have a Snapdragon variant, you can't flash that ROM.

Hey guys!
This is my first ever thread on XDA! And my problem goes like
I have a Asus max Pro m2 device. And also I'm familiar with things like custom ROMs, custom recovery, rooting and all that stuff. I have been using custom ROMs, etc etc.. from a long time. And I use TWRP as my recovery system. Recently I tried to install lineage OS on my phone, but it gave me an error 7. Then I searched on google about what is error 7. Tried all the solutions, nothing worked. Then I thought it's happening because of my phone's modem. So I searched for the latest modem file for my device, then I got a file on XDA. And that was a TWRP backup file of the Modem and the EFS. So I downloaded it and restore the file through TWRP. And from there, I'm not able to install any custom rom on my device. I tried many of them but couldn't. All of them have me an error 7.
But before that everything was fine. I was in evolution X custom rom. And that file ruined my device completely. Now I'm completely helpless, clueless. So what to do. Any expert suggestions?
PLEASE RESPOND!!!
Hi, if you didn´t solve this problem watch this video that has the solution for asus zenfone max pro m2 brick devices. Keep in mind that when you do this, the phone gonna be with the first oreo version, relock bootloader and unroot your device so you have to uptade manually.
Copy the zip ROM file to your PC and unzip it using your favorite archiver (for example, 7-zip);
After unpacking find META-INF folder and go the META-INF/com/google/android line. In the last directory you will find two files called "update-binary" and "updater-script". We are interested in the latter one;
Rename "updater-script" to "updater-script.txt" and open it in any text editor (for instance, Notepad++);
Now remove the line starting with "assert" to the next semi-colon. Usually it is the first or a few first lines in the beginning of the text file;
Save the modified file;
Rename "updater-script.txt" back to "updater-script";
Update all files you have unpacked;
Copy the modified zip-file on your phone;
Reboot your Android device to recovery mode and try to update it again. Status Error 7 should be gone.
