I tried Power+Vol_up which is not success to goto Preloader

Then i tried Hold Vol_down and plug USB, it can load the driver but it will use MediaTek USB VCOM (Android) by default

I try to flash the Ubuntu Rom by SP Tools it show the following error:

---------------------------

Smart Phone Flash Tool

---------------------------

BROM ERROR : S_AUTH_HANDLE_IS_NOT_READY (5000)

[User] This is a secure Base-band Chip! Please select the authentication file first.

[HINT]:

---------------------------

&OK &Help

---------------------------

I try to change the driver to MediaTek PreLoader USB VCOM (Android) it still not work.

Maybe I need to try unlock bootloader then test it again.(Or is there anyone already tried to unlock bootloader and then flash it?)

On the other hand, I find that [MENTION=6296892]Naphtha[/MENTION] you try short the PIN at the motherboard as the following thread:

http://forum.datadevelopement.com/meizu-mx/general/meizu-mx4-partitioning-t3164344

Is it the missing part of the process?

(Update)

I already unloack the bootloader, but it still show the auth error(At stock recovery and philz recovery).

but i have a question, is I need to flash the ubuntu recovery first before using SP Tool to flash the ROM?
[Meizu MX] Naphtha:
Nope, watch my video tutorial. For change the driver, just go in the manager and when popup the wrong driver, push right button and delete it (more times you need to do this 3-4 times).

[MENTION=3512289]boris2005[/MENTION] delete the driver don't upgrade, do this tentative. Next step is reinstall the driver from the folder drivers&tool
[Meizu MX] boris2005:
I Uninstall and delete all the driver of the device and finally it show Unknow device and can't auto install any driver now.

https://www.dropbox.com/s/76yjk44gp79tfp3/8.png?dl=0

Then which one should I do next?

1) use Install.bat in Drivers Hard Reset to install the driver?

2) use Device manager auto search driver in Drivers Hard Reset folder?

3) choose "cdc-acm.inf" and install the "MediaTek PreLoader USB VCOM (Android)" driver myself

And is the MX4 have different version of hardware make the behavior of the SP Tool have different result?It is because I boot with PowerKey+VolUp is go to recovery, boot with VolDown and plug USB is goto META mode. it seems is not the same as your machine.
[Meizu MX] Naphtha:
Install manually and choose the folder in "drivers&tool". He search it alone and preloader popup.
[Meizu MX] boris2005:
It search the folder:

Then it will install MTK USB Port automatically:

I still get the 5000 error at SP Tool
[Meizu MX] Naphtha:

[Meizu MX] tomas.oqvist:
Any news on this?

I have a Chinese MX4, on which I have installed version 4.2.8.2A and successfully unlocked the bootloader according to this thread. I bought this phone about a year ago with Ubuntu Touch in mind and now it seems that there is a way as explained in this thread. However, like many others, my MX4 doesn't behave as the phone in Naptha's videos or descriptions. So far, I haven't bricked my phone or loaded any other Android image. But one thing I wonder is if Ubuntu can be flashed on a phone without Philz recovery and not being soft bricked? Also, has anyone had any luck fastboot flashing Ubuntu to an unlocked phone?

I would really like to see some progress on this.

Thank you,

Tomas
[Meizu MX] Naphtha:
For now no progress :(
[Meizu MX] Danj1:
Hi there.

I'm reading MX4 threads for some time now and finally flashed my MX4 (Chinese Version) to CM 12.1. As I used Ubuntu-touch on a BQ Aquaris E4.5 for a while and now on my Nexus 4, I also would like to test Ubuntu-touch on the MX4.

For the Nexus 4 there is good guide on the Ubuntu wiki for Android/Ubuntu-touch dual boot: https://wiki.ubuntu.com/Touch/DualBootInstallation

As I understood, they use a shell script to "install" an Ubuntu image to the recovery partition.

My question now: Would it be possible if we just edit the script to be compatible with arale/mx4 devices? Has anyone tried this out yet?

Thanks in advance
[Meizu MX] Naphtha:
An guy is working on that :fingers-crossed:
[Meizu MX] Danj1:
Hi,

thanks for that info. Is there any possibility participating on that process? Something like a GitHub project we can follow/contribute to?

Have an mx4 android version and want install ubuntu touch?
[Meizu MX] Danj1:
Yes, that's exactly the case. I have Chinese 32gb version with unlocked bootloader and CM 12.1. I would like to have the same dual boot configuration as possible on the nexus 4 until Ubuntu touch is stable enough for my daily usage. As I understood flashing the arale Ubuntu touch image with MTK-tool is not possible due to partition incompatibility or flashing restrictions.

How to know if my phone have a chipset security.

Finally after a month, a got my meizu mx4 32GB new from amazon

a want to install ubuntu touch, but reading all post, i see a lot of complaint about " chipset security "

and then bricked phones for this reason.

is there any tutorial on how to know if a phone have this chipset.

my phone is unlocked Flyme Os. 4.2.2.2A
[Meizu MX] jorj.jorjevi4:
Just to reconfirm:

- when I push vol.UP + Power - the device goes into recovery mode and in my device manager I see a "Recovery" device.

- when I push vol.DOWN+Power I really get an identified device, for which Windows tries to install a proper driver. I was able to install the provided "Preboot loader" drivers and my win7 detects the device as "Preloader USB VCOM Port". However the SPTOOL returns an error related to security chip. This error was discussed above.

MX4 16gb, ver 4.5.7.I, i did not unlock the BL

Maybe for different versions you need to try vol.DOWN+Power button instead of Vol.UP.

nome for me before i bricked my phon not using this method :D was same because vol down is bootrom

Just to add to this:

I have a meizu mx4 ubuntu edition.

It went into a serious bootloop and the recovery got corrupt.

The only available tool was fastboot but i couldnt write to recovery partition.

In windows 10 i was unable to get the Flash tool to work to the phone. the device was shown in device manager but no writing.

I installed ubuntu on a spare drive and used the ubuntu flash tool with the scatter image provided here.

It wouldnt work with power + volume up , but strangely worked when i plugged in and held volume down.

Phone now saved... thank you very much for all your effort on this device ... my phone works perfect now and i am very happy!!!!

[Meizu MX] meh301:
We may have found a possible way to get the preloader to work and to truly unlock the bootloader but someone needs to test it out (it might brick your device, be warned).

What you need is a working meizu MX4 with the unlock bootloader hack (I prefer to call it the unlock fastboot hack).

There is one file in the factory ROM that is very interesting which is the third secro image, the sro-unlock-sign.img. Theoretically you should be able to flash this via fastboot to the secro partition and by doing so, your phone SHOULD be fully unlocked and work in preloader mode.

If this works, it should prevent any future bricks and allow for safe modification and installation of any OS.

[Meizu MX] turbotuck:
I'll consider this. I have a MX4 which came with 4.5.7i, downgraded to 4.2.8.2a and unlocked via the "unlock app", now with custom recovery and emmaus CM12.1.

When you say factory rom i'm guessing I have to use flyme 4.2.8.2a?

I'll look into it and then make a decision.
[Meizu MX] meh301:
No, there are stock android kitkat factory ROMs floating around on the internet which include all the signed images for flashing via flash tool

Also I flashed an unlocked secro partition and my phone works fine. Issue is, that only gets rid of the second secure boot check, there is still the first secure boot check which involves the preloader, the seccfg partition and the seclib binary. This is much harder to hack since there's a huge chance of brick
[Meizu MX] turbotuck:
Ah, that makes more sense.

So the risk is that the first secure boot check might notice the changes? Better odds than I initially thought though. But what will this resolve? Are we hoping it will allow us to change partition sizes and give us more access?
[Meizu MX] meh301:
Well with a full unlock we would be able to do anything we would want with sp flash tools, that includes partition changes.
[Meizu MX] turbotuck:
Ok, so we are talking about a full unlock. I'll gather the files and have a look tomorrow, I think I have downloaded the factory rom already and SP Tool is up and running. I'll probably setup OBS so I can make a video of the process if anyone wants it.
[Meizu MX] meh301:
What meizu MX4 do you have? Android or ubuntu? Also, did you already follow the unlock bootloader hack? Because you can't normally flash via flash tools so every modification is done via fastboot
[Meizu MX] turbotuck:
If I had an Ubuntu Edition I wouldn't be doing this. As I said earlier, my phone came with Flyme 4.5.7i(new motherboard, old one had 4.0.4U), and I followed this tutorial, and I now have TeamWin 2.8.6.0(4pda, ported) and CM12.1.

Is there a specific method for unlocking you're referring to?

I know about flash tools, I've tried with 2 different motherboards and got the secure baseband chip error.

EDIT/Update: Can't seem to find sro-unlock-sign.img in the factory kitkat rom, any tips?
[Meizu MX] meh301:
https://mega.nz/#F!MkNnETAZ!GYPnBc8B_LMgdR1fNI0c_g this should have it (but the sro-unlock.img is not in a fastboot flashing state here)

so here's the flashable one:

https://mega.nz/#!bNYFhKBK!9AqawSiuGx4pNjLB6GBbpEq_WH2Lan1HytXneY6ardY
[Meizu MX] turbotuck:
Thanks!

Just to be sure, as I've not flashed anything but recovery through fastboot, the partition is called "secro"? Making the command "fastboot flash secro secro.img" ?

And thanks again for helping, I've worked a lot with unlocking, rooting on different phones, but never something this complicated. Hopefully it will work, and in worst case scenario I at least hope it wont brick. But at least we're trying.
[Meizu MX] meh301:
Yes that is the way to flash it. There is also a fastboot getvar all log one of the pages of this very thread with useful partition info which I constantly refer to since we can't use the getvar function...

And as a statement, corrupting secro partition shouldn't be that big of an issue (you should always back it up beforehand though) as it is not in direct relation with preloader and is loaded after fastboot mode.
[Meizu MX] turbotuck:
Flashing went fine, and no brick :) Going to boot up windows now so I can try SP Flash Tool(ubuntu version doesn't always work).

Will keep updating

Update: Still not connected to preloader. PID0003 even with preloader driver installed.
[Meizu MX] meh301:
Preloader won't work even after that as I previously stated - flashing secro partition breaks the second secure boot stage which involves partition verification; there's still the first stage which I'm trying to logically work out as information on what the first stage actually does is next to non-existent...

One thing I am sure of though, the secro partition needed to go so that the security verified partitions can be modified in the eventuality of truly unlocking the device.

If you could help, it would be great to figure out what the seccfg partition actually has on it for configuration, it would also be good to know in general what the seclib binary does with both the preloader and the seccfg partition, and finally, and probably the easiest, figuring out a way to make a dump/backup of the preloader partition while the phone is booted (all dumps show up as blank so the people who attempted to flash preloader via fastboot may have never had access in the first place causing brick)
[Meizu MX] turbotuck:
Ah, yes, but I just had to try.

I'll see what I can do. But can't promise anything, my skills are limited, but I'm very keen on learning.
[Meizu MX] jcache:
Hi all,

may I know which firmware version has been successfully flashed over with ubuntu ROM?

I have 4.5.7A and I guess by reading some threads I can't downgrade to 4.2.8.2A.

Bye the way I was not able to install preloader driver on a clean win7 installation cause my MX4 is catched by a generic driver and not correctly detected. Forcing the driver resulted in bad installation. If no solution comes I'll try a new installation.
[Meizu MX] turbotuck:
You cannot yet(install ubuntu touch on a flyme mx4). The issue is we don't have a full unlock yet, which means we don't have access to repartition and preloader.

I have tried everything, and the solution is getting closer but the phone is more or less locked down, and will brick if you try to tamper with it(happened to me once). This solution only worked for Naphtha, but no one else. You'll most likely get a "Secure base-band chip" error.

If I were you, I would try installing 4.2.8.2A if you want to "unlock" and then you could install CM12.1. I did this from 4.5.7I and it worked perfectly. I used this thread.

There are many threads about this issue, if you have more questions. Just reading this thread will give you a good insight.

[X 2014 Q&A, Help & Troubleshooting] Ownage516:
Even after a year on Android, I'm quite the novice, so please bear with me. So, I rooted my Moto X '14 using CF Autoroot because it was so easy. But, I had no idea how to unroot. So I googled some stuff and I attempted to flash back to total stock rooted rom and recovery. Foolishly, I picked the option to not wipe. So, when it rebooted, it went to the boot screen and crashed.

After trying everything, I realized I had no choice and did an external reset. So, hello 2014 because I'm back on KitKat but still was rooted. After looking around, I realized I can 'unroot' by pressing the option on SuperSU. But, I think all I did was revoke root access because on the bootloader, it still says modified.

I tried to go back to lolipop, but every time I take the OTA, the install crashes, but my phone works fine. So, what I wanna know is how I can go back to stock. Is it easy as flashing as flashing a 5.0 factory image? Or is there more I have to do?
