Hi All,
Apologies if I am asking the same question others have in the past I am just wanting to make certain I am following the correct steps.
My Zenfone has an unlocked bootloader, SSJs TWRP and is rooted with the SuperZen R15 firmware.
I am wanting to return to stock recovery and stock unrooted system. Can I just ADB sideload the latest ASUS firmware via TWRPs advanced option or are there other steps I need to take first? Do I need to unroot this firmware first or will the sideload sort all of that out for me?
Hope my question makes sense!
Thanks everyone!
Hi again everyone.
I just tried and the process was successful. For anyone interested I followed the following steps.
1. Unroot via SuperSU
2. Fastboot flash recovery, boot and droidboot images
3. ADB sideload full rom from Asus website using stock recovery
All of these steps have instructions or tutorials on this site and others.
Hope this helps anyone looking for this info.
Where can I get the recovery, boot, and droidboot images?

Same steps for cm12? I just want to get back to stock i'm sick of playing around with a alpha firmware at the moment. I've already wasted a good portion of my day off. Will this get rid of white boot screen
Yeah maybe, you can always try.
I don't think it will remove the white boot screen, you would have to flash the black one before removing TWRP.
Hello devs,
I upgraded my Realme X to android 10 using OTA.
Although there are no serious bugs, the UI has minor glitches now and then. But the camera has lost its quality significantly. It is taking comparatively bad photos now when compared to Android 9.
Can You kindly write a guide on how to downgrade to Android 9? It will be really appreciated.
Thank You in advance.

Download Stock rom released on 19th Feb and flash it manually if your bootloader is unlocked or if you have custom recovery

Bootloader is locked. Can't I flash older versions?
I have the same query. Any help would be highly appreciated.
Bootloader is locked. I just purchased the phone and upgraded to Realme UI. Now I want to downgrade to colorOS so I can either use it or flash the phone to other ROM(s) which is completely impossible as of now in Realme UI.
U can unlock bootloader using In depth test app and adb but u can't use TWRP because TWRP is not supported in android 10.
What about fastboot? Can we flash Android 9 using fastboot? Have you successfully downgraded?

Hi
I've bricked my realme x and that lead me to start searching ow to unbrick it, and with that i can tell you there's a way to make a downgrade of the android version.
The first thing you need to have is the .ofp file of the software version you want (if you have the india/global version you will not have any problem finding it, but if you have the chinese version you probably could not find it *i've been searching a lot for this file, if you find it, please let me know*)
once you have the ofp file you need the flashing tool of oppo, known as msmdownload tool, the issue with this is the tool will ask you for username and password, because its for oppo workers, and a lot of patched versions don't reconize the file.
If you made this far its pretty simple, select the ofp file, connect the device pressing volumen + and volumen -, and push in the icon of flash.
you can do it in another way, unlocking the bootloader (theres a tutorial in this forum), and then flashing a recovery (you migth flash a custom rom first via adb/fastboot) a zip file with the twrp, and then using the flashable zip of color OS
I hope this help you, but if you're not very mastered in this i reccomend u let realme work of improving the rom or using a gcam

you have to flash the recovery after flashing another rom
thats why i suggest you flashing a custom rom via ADB and then flashing the color os rom

It is very simple if you say "I DON'T KNOW"
I am not responsible for any brick.
I tested this guide myself and decided to share it.
Make a backup before this guide because you will lose your data!
The unlock method has been updated and now you can unlock the bootloader more easily without the risk of bricking after an OTA and without changing the bootloader.
Now you can safely unlock the bootloader using mtkclient.
Link: https://github.com/bkerler/mtkclient
TWRP can be installed via mtkclient or manually from rooted Android.
TWRP Download link: https://github.com/XRedCubeX/twrp_meizu_m5c/releases
IF you unlocked the bootloader with the old method you can follow these steps:
1) Download the attached package.
2) Download OTA zip from flyme, link: http://www.flymeos.com/firmwarelist?modelId=70&type=1
3) Download the latest version of SP Flash Tool.
4) Download MTKClient and follow the instructions to install it.
5) Power off the phone and keep unplugged it from PC.
6) Open SP Flash Tool, select the downloaded package and select all partitions, then press the download button, don't plug phone for now.
7) Boot to recovery with vol +, plug the phone on PC, depending on recovery, TWRP or stock, use adb sideload or put update.zip in internal memory and install the zip.
8) Let the phone reboot or reboot it manually.
9) Now start the flash from SP Flash tool automatically, let it finish.
10) After the flash, unplug the phone and reboot into recovery.
11) Paste the update.zip in the phone and flash it.
12) After reboot, let your phone reboot into android and power off.
13) You can follow the guide to unlock bootloader with mtkclient.
FAQ:
A) But will I lose the data with this guide?
Yes.
Make sure to back up your data in any case!
B) But this guide is a bit different than usual, where is "fastboot oem unlock"? Or "fastboot flashing unlock"?
Meizu has not implemented an unlock command and in this case to unlock the bootloader we have to use a tool that makes us change the unlock status.
C) Are there Custom ROMs?
There is only one custom ROM for this device, the Lineage OS 14 but I advise against using it because it has a bit of a bug but I haven't had more time to work on it yet.
D) But wasn't the guide different?
It has been updated with a better method with more advantages.
E) My device is in Hard Brick! How can I solve?
There are various types of Hard Brick and it depends from situation to situation.
F) I have installed Lineage OS 14 but I am not satisfied, I want to go back to Flyme!
Flash update.zip from official website.
G) Can I relock the bootloader?
From MTKClient readme:
for relocking use:
python mtk da seccfg lock
Click to expand...
Click to collapse
H) TWRP? I am interested in Device Tree, where is the link?
Here: https://github.com/XRedCubeX/twrp_meizu_m5c
I) I have a Meizu A5 (Chinese M5c) will it work on it?
I can't assure you anything but it could work, the only way to be sure is to test on a Meizu A5.
J) Can I flash twrp from fastboot?
Fastboot refuses to flash partitions, strangely, I don't know if downgrade or anything changes the situation but for now I was able to flash it with mtkclient.
I can remove the FlameOs from the Meizu M5c and install a custom rom. So far I haven't found any rom for this device?

You unplugged the device while it was formatting, consequently it no longer has the bootloader, that error means that the device needs an authorization file that unfortunately only meizu has, shortly if I can try to release a tool to unbrick it in cases similar to these

Ok i found a working guide, tried on my M5c and it works:
Search on YouTube: flash mtk without da ,
You will find a video called, just exactly as I write here: "How to flash MTK secure boot devices without a custom DA" and follow the video tutorial for unbrick your device.
P.S:Obviously when the guide ends you flash the ROM from SP flash tool as you normally would

XRed_CubeX, I followed the tutorial from start to finish. I used the SP Flash Tool to install the M5c stock ROM, the ROM was flashed 100%, but after disconnecting the USB cable the phone did not turn on.

Have you flashed the Stock ROM or the Engineering ROM? I remind you that even if you have flashed the eng rom only once previously, you can no longer return to the flyme bootloader so use the normal stock ROM but you will have to flash the Engineering rom

Well, I flashed the stock ROM a second time, using the Firmware Upgrade option, and it worked. My phone turned on and I'm in the initial setup screen.
By the way, this Engineering ROM is the ROM you shared above? Do you think it is stable enough to be used? Maybe another day I'll install it, with care to not do anything wrong again

Yes, the ROM in this thread is ROM engineering, about the stability I can't tell you why I haven't tested it, the main purpose FOR ME was to get the bootloader unlock with this ROM, if you want to switch to ROM engineering you CAN install the flyme after installed the Engineering ROM but you must always modify the OTA zip so that some partitions do not flash but if you are interested I will talk about it in more detail and maybe I will give you a hand to flash flyme safely on bootloader engineering

Actually, the ROM I installed with SP Flash Tools was not the update.zip from the official Flyme OS website. I downloaded the stock rom from needrom.
I have done this several times before.
But now, strangely I can no longer update to the latest version. The version I'm running is Flyme 6.0.2.0G. I tried to download the update.zip file and install it manually by clicking on it, and it appeared "corrupted file". I also tried to use the Update application and "network error" appeared. But everything else is working perfectly.

Ok, I'll explain in detail how it works: In the guide you will have read that you cannot return to the flyme using the stock rom or an unmodified OTA. This is a tip because once you flash the Engineering ROM, the engineering bootloader (which is essential for unlocking) will also be flashed, but the problem is that if you flash the stock bootloader (the flyme one, the one you surely have when you get the phone), the device for a reason unknown to me, probably the Engineering ROM modifies something in the device (?) and then goes into brick if you try to return to the flyme bootloader. To flash an OTA flyme on TWRP, you must first have some precautions: you must take the OTA on your computer (or a file explorer capable of editing zip files) and remove the following files: lk.bin preloader.bin (it will have a name longer but you still have to remove that) and tz.bin / trustzone.bin. Done like this, now the OTA becomes safe to install, you install it from TWRP, at the end of the flash it will give you an error but it is because it does not find the files we have removed but we can safely ignore it because it will have successfully installed the flyme on the device.
Regarding lineage: I'm still working on it a bit and gradually I'm discovering bugs. I already warn you that the camera will not work in the Lineage, I have tried in every way to try to make it work but it does not want to go, I have asked for help everywhere but no one has been able to answer so I do not know what to do, for the rest I want to keep a little longer the ROM under test to fix the remaining bugs
Can use some help flashing back to stock
Can't seem to find a decent working rom for Pixel C Tab been running LineageOS 18.1 and Chrome is just to buggy super slow loading and freezing up unusable seems to be an issue with all the dragon roms
Unless someone knows a better solution guess i need some help to restore back to Factory image
Here you can find the original firmware files. Latest one will be Android 8.1 Oreo. There will be no security patches.

It is... Flash it via TWRP after wiping your device and profit. Think about that´s a factory image with own recovery, lost root etc... And sorry for my ignorance - but as a senior XDA member you should know how to flash original firmware...
If you made a mistake like doing fastboot flash boot init_boot
You have a bad boot now or boot loop, the solution is
Flash Boot files of the exact running OS version from fastbootD
This will fix the issue
I have extracted this from the partition backup application hopefully it will work for you
Boot Files below
Can you access fastboot? If not, it's hard bricked. You need to goto service centre or Get it flashed remotely by paying someone.

did you get a full zip rom by chance? idk why it's so hard to find one or why Oneplus doesn't offer downloads from their site anymore....
What i find funny is that by following that guide 100% would have you up and running with root. This tells me following directions is hard to since we can only give directions and hope you can following them. Reading the full guide before proceeding with it. Step 6: BOOT the kernel. DO NOT EVER FLASH THIS PHONE!
