[Xperia Z2 Q&A, Help & Troubleshooting] mr.loverlover:
New cm 12.1 doesn't allow for most rom installations, so you just always have to change your recovery (like eg. Cwm) and then flash your rom (and recovery if it's needed).

[Xperia Z2 Q&A, Help & Troubleshooting] markussk:
Just to make sure I got that right: Before flashing the new 12.1 versions I have to install another recovery, then flash the new rom version? Why is that so?
[Xperia Z2 Q&A, Help & Troubleshooting] mr.loverlover:
Yeah. Exactly. The new recovery that is included in cm12.1 allows flashing only few files. Idk why they keep using it, but we just have to use other recovery to flash stuff.

I will try that, thanks a lot. Odd anyways. Can you recommend a recovery that works well with CM?
[Xperia Z2 Q&A, Help & Troubleshooting] mr.loverlover:
Nah. Unfortunately not. I don't use cm these days by my own anymore. Somebody else would had to come with help.

FYI now really weird, even this post didn't come out right on the initial posting. The information attempts to be there when I edit it (additional CODE boxes, there are clearly four total CODE boxes with both beginning and ending CODE tags when I posted and when I edit the post), but as usual, URLs and other information is missing from my examples. I'll probably be forced to give screenshots when I have time later.
[OnePlus 2 Q&A, Help & Troubleshooting] napes22:
I've encountered an odd error, and I'd prefer not to factory reset. Ever since I upgraded to Oxygen OS2.1 (and subsequently installed AK Kernel), nothing happens when I plug my phone into any computer. However as soon as I disable USB Debugging in Dev Settings, the phone is immediately recognized. Has anyone else encountered this, and if so, how did you fix it?
[OnePlus 2 Q&A, Help & Troubleshooting] dcontrol:
The drivers that are on the phone didn't work for me with debugging on , assuming that's what you used? I grabbed the drivers from the android sdk and that seems to work fine.
[OnePlus 2 Q&A, Help & Troubleshooting] napes22:
I'll give that a try. Thanks!

How to enter this mode for drivers? Vol up + power enter recovery mode. And do we need to have unlocked bootloader for that or what we have to do? Because it's not working
[Meizu MX] Naphtha:
Little bit first of recovery, and turn on with volume up from first...you need to see fasty on the device manager the unknown device

Turn off the phone---> Plug In the phone to the pc----->Hold volume up + Power---> In "device manager" popup an unknown device (really fasty)----> install the driver (vcom preloader listed now!!)---> turn off the phone-----> open sp tool---> load scatter----> set firmware upgrade-----> push download-----> Hold the volume up+power-----> flashing start (if you do all good!!)
[Meizu MX] DeadAngel43:
When I am doing this, nothing popup in device manager, if I keep up holding volume up + power phone is rebooting every time, when I stop holding this buttons my phone goes to recovery. What am I doing wrong?

If reboot is ok... pay attention on device menager...popup really fasty an new device and disapper

Preloader come and i try to flash ubuntu with SP Tool...and work :fingers-crossed:
[Meizu MX] DeadAngel43:
I've installed correct drivers, sp tool says it's need auth file first. [MENTION=6296892]Naphtha[/MENTION] when you had flyme do you had Meizu logo as a boot animation or Flyme? Have you installed any flyme on lollipop?

go into fastboot (power + vol down)

[Meizu MX] aa4772041:
e,i 'm come from China, and now i have some questions. my pc no have this PLUG THE PHONE TO THE PC AND HOLD VOLUME UP + POWER BUTTON (HOLD IT AND WATCH DEVICE MANAGER A UNKNOWN DEVICE POPUP FASTY) and pc have

mt65xx Android phone why？
[Meizu MX] Naphtha:
actually i have flashed ubuntu and in this version fastboot and bootloader are unlocked..(i want test it today)

32 gb replacement? They don't know this, aren't able to flash ubuntu on customer service... When i turned on the phone for the first time, he has 4.2.8.2 I version and when i reflash it with 4.2.8.2a for install the cynogen ,give me bootloop (flyme logo bootloop), after this i decide to return back to the I version, but nothing change. But in the same time i see this popup device on device manager, and i decide to test again the SP Tool (my pc was clean without drivers for the phone). After a little bit searching, i have founded the Bq drivers and when i have installed it, the preloader popup. This give me the sprint for flash the phone with SP Tool of Bq....and "BOOM" flashed.

For the first 30 seconds I did not understand nothing..... I have bricked 4 phones in an attempt to do it by myself.

Next week an MX4 32gb Chinese version come to me. I will try it on this other phone..:fingers-crossed:
[Meizu MX] Naphtha:
more people aren't able to do it...and i don't know why :(

Standing by to test

I have just bought brand new MX4, it has Flyme OS 4.2.2.2I. Right now i have only Ubuntu laptop, so standing by to get hands on Windows workstation and will try to flash and testing those great guide at beginning of next week. Thumbs up for your works Naphtha, i am desperate to run Ubuntu on my phone at last and show finger to both Apple and Google !
[Meizu MX] Naphtha:
You can try to flash the rom with SP Tool for ubuntu :) http://www.mibqyyo.com/en-download/2015/05/22/flash-tools-ubuntu/
[Meizu MX] deu23:
Tried, so far no results.

I have firmware 4.2.2.2I, downloaded 4.2.8.2A from flyme web, when i push volume up and power on, it mounts, i upload update.zip into recovery, It takes archive, always ends up with Firmware corrupt and wont update.

Tried also push volume up and power up when download started on SP, will never find serial port (ens up in flyme firmware updater always). When i power off and power on with cable, no change it normally boots.

Only option is to go fastboot by volume down and power on, then the SP Flash detects ttyS0, but fails with S_BROM_DOWNLOAD_DA_FAIL (2004) OR S_BROM_CMD_STARTCMD_FAIL (2005)

Seems no luck even to put the firmware which can unlock bootloader - no idea why the update.zip always ends up with Firmware corrupt.

Do you have any Ubuntu phones on stock ? Maybe easier to buy, dont have that much time to mess up with mysterious chinese firmware bugs - problem is that this phone with ubuntu is virtually unable to get, with Meizu playing puzzle game with users...
[Meizu MX] Naphtha:
On manager device no popup device?
[Meizu MX] deu23:
For now testing from Ubuntu 14.10 only - will take me some time to get some Windows machine to try. Testing to dowload I version of fimware from Meizu now, so i can move on Bootloader unlock. Doing anything i can - Volume UP + Power On doesnt work in any combination - SP tool only able to look up serial port after Volume Down + Power On, but fails anyway with errors above.
[Meizu MX] Naphtha:
If you see my video i do it with Volume Up+ Power. I don't understand how many people aren't able at do it... I care the preloader is standard for all the MX4 (mine like your)... :confused:
[Meizu MX] deu23:
Interesting. Volume UP + Power will ALWAYS bring me to firmware upgrade page, without exposing serial port to SP flash tool. I tried push Volume UP and then Power, Power and then Volume Up, simultaneously, always same result, firmware upgrade page. Also, if i hold Volume UP and Power, it will cycle with vibration and Meizu logo in loops, until i release - then i end up in firmware upgrade page again. Really no way for me to use Volume UP + Power to expose serial port for SP flash tool - unless you have some special black magic how to push buttons.

---------- Post added at 09:51 PM ---------- Previous post was at 09:34 PM ----------

I am curious too, can you try ? Maybe your board is just completely unlocked bootloader and propably this happened due to guys at Meizu service doing this while refurbishing board ?
[Meizu MX] richish:
If you have " I " FW version then u will not be able to flash "A" FW ( i was't able to do it )

I had 4.2.2.2 when i bought phone i was able to update ONLY OFFICIAL 4.2.8.2 FW from flyme.cn and then to 4.5.5. ALL of " A " version got "FC" error

P.S. A read that lot of guys cant upgrade/ downgrade " I " version from flyme.cn, try to download from other sites.

I have I version, and cant flash anything else than I. Yesterday i finally flashed 4.2.8.2I. Tried to flash 4.2.8.2A, no luck firmware corrupt error.

Lets look on my fastboot:

<pre>

root@deu-thinkpad-x301:/home/deu/work/ubuntuphone/unlock/copy# fastboot devices

75HACLC9YV36	fastboot

</pre>

My guess is this indicates your fastboot is UNLOCKED, while mine is LOCKED. Most propably because of this SP tools will fail as well. Next think to do i try is to unlock the bootloader via method on russian forums, lets see if fastboot changes its attitude after that.
[Meizu MX] Naphtha:
Yes, do it. After this, flash the recovery of ubuntu touch and go in Ubuntu desktop and download the version with phone connected and developer options opened. Open terminal and do this command: ubuntu-device-flash touch --channel=ubuntu-touch/stable/meizu.en --device=arale --bootstrap

When finish the download, have a little bit possibility of starting the flashing. Be patiente take a lot of time.
[Meizu MX] zspudsz:
i also cant install the preloader. my M1 note can be read by the pc but my mx4 cant. is it an issue with the mt6595?
[Meizu MX] Naphtha:
Yep, now i'm at work i want try later. How meizu can lock preloader? mmmm
[Meizu MX] Naphtha:
With this recovery don't work the command: adb shell
[Meizu MX] deu23:
Studied sources of ubuntu-device-flash, its simply using fastboot as wrapper. Here is the commands which result in failures on flash:

Obviously, fastboot is locked for partition formatting

Next error:

Here fastboot doesnt support booting of just uploaded recovery, what a shame. It is 100% your phone has unlocked Fastboot, that can do what this cant do. My assumtion ? Result of Meizu's stupid lock policy, this ****ing phone of mine for sure isnt "Unlocked"
[Meizu MX] Naphtha:

If you change the build.prop of your phone after installing the apk, the program recognize the phone. Change all the entries mx4 in "arale", reboot and open the program: he recognize the channel and download all but you need to build the "dualboot.sh".
[Meizu MX] deu23:
I dont think i can use it for anything ATM, but thanks anyway. The way would be now to figure out to unlock or update Fastboot (which is highly unlikely), or to fix Ubuntu's recovery tool so it can work in some kind of workaround mode to flash even with broken fastboot. Another way around is to use SP tool and do complete firmware upload in META MODE. BUT, i was not able to enter the META MODE and intiate SP Flash tool. Read suggestions on http://xdaforums.com/showpost.php?p=34914486&postcount=3 , looked at video people.canonical.com/~alextu/tangxi/tmp/VID_20150408_162220.mp4, no success, cant enter META MODE by ANY MEANS.

[Meizu MX] Naphtha:
I remember this popup device from my others 3 phones (mx4 bricked..). Plug out the battery and plug in the usb, power and volume up(but in this case you need to plug out the usb for do another tentative). I remember this popup device in all the MX4, but the drivers are all time wrong. If you can test it..
[Meizu MX] deu23:
Nope, i have another brick. After little changes on filesystem reinstalled Flyme, but it wont up anymore, just flipping logo. It did update correctly, though. Another problem is that Flyme updated fastboot to totally crippled one:

fastboot flash recovery meizu-unlock/custom-recovery_mx4/philz-mx4.img
sending 'recovery' (10000 KB)...
OKAY [ 0.681s]
writing 'recovery'...
FAILED (remote:
Security deny - Err:0x2017
)
finished. total time: 0.747s

So, right now i cant do anything, neither flash Philz and fix, neither boot Flyme (to fix fastboot again). I will simply return this to customer service, lets hope they reflash and send back. Dont you have your Ubuntu phone for sale, just by accident ? I will try to get one no matter what, i am quite annoyed already by this stupidity around - not only you cant order the MX4 with Ubuntu because its out of stock in EU, but also stupid policy with locking bootloaders, preventing you to install one on this otherwise great piece of hardware. This agains reminds me Apple's plays with jailbreaks, and i just hate this, especially when comes to Opensource which Ubuntu is....

I start the MX4 with Power+Vol UP, it only show meizu logo and goto recovery.

I find that it install the default WPD FileSystem Volume Driver(Show "Recovery" at device manager).

It seems not the Preloader we needed.

And i try to reload the driver and force install the driver you provided at Drivers&Tool it show an error message said it is not supported.

I am using MX4 internation version and using Windows 7 SP1 for flash the MX4

Do you have any idea about it?
