Tried that.. I wrote an essay here about my problems with phone and fixes i did but peace of crap restarted before i could post. :'( im so frustrated i can't explain you... I have succeeded in reboot error and it worked for a couple of days but than sim had problems 'cause i messed up nvram (didnt backup efs nvram imei) and sim worked only for sms, calls just hang. Now there is a whole story what i did and didn't but eventually my problem persists. It reboots every now and then. Sometimes when scrolling 9gag, taking pic with cam (fixed with gapps flash), basically when i take phone for a ride that's cpu/gpu/memory heavy it dies like it took rpg in the face.. It would be awesome if someone has, and is willing to share twrp backup of fully functional rom so i could compare differences and maybe find the solution..

Is there any way to update the phone from nougat to oreo treble enable?
[Android Software Development] ghost45:
HI i know that you became crazy with this phone ...me too!! :silly:!!!

Yes probably there is others problems always with flashtool!

This device seems not dialogue correctly with flashtool...

to be continue....I think the solution is fastboot!

If your phone don't realive and have black screen leave more time under usb connection to recharge and try again..

Use Firmware Upgrade in the flash tool?
[Android Software Development] ghost45:
Yes probably there are others problems always with flashtool!

Probably is the preloader i dont' know at this point! Is a terrible device!

flash with flashtool all the firmware without flag the preloader..

I've found an interesting thing - Vernee Mix 2 toolkit. It's based on @Cleopatra Bianchi TWRP, but with decryption support.

Anyone has tried it?

Also, post there: https://xdaforums.com/showthread.php?t=1660354&page=2254. Maybe we will get our own MIX 2 XDA section, that would be cool - but we have chance only when you write a request in linked thread.

@ghost45 could u be kind and, at point 5, write the exact comands to be written in adb, because i'm noob at using adb :crying:
[Android Software Development] ghost45:
You must copy the files of the firmware in the adb folder after decompressed....

Command to use :

You probably are in c:\ xxx folder

Cd x: (letter of the DRIVE where is the adb decompressed)

Cd: adb

Fastboot flash system system.img

Fastboot flash userdata userdata.img

Fastboot flash recovery recovery.img

For moment do not install preloader !
[Android Software Development] Cleopatra Bianchi:
question

Any of you have tried to unpack the system.img ?
[Android Software Development] MSD-Amadeus:
I tried it with Tools Unpack System and with SuperR's Kitchen.

Without result.

If it is extracted, it does not have to have signature.:confused:
[Android Software Development] ghost45:
This is the screenshots of the system :

i think the probem is the preloader files....
[Android Software Development] Cleopatra Bianchi:
answer

@ghost45 :

The preloader had nothing to do with the unpacking process of your system.img

Do you have tried to unpack your system.img with the same tools used by @MSD-Amadeus ?

@MSD-Amadeus :

I have also tried to unpack it with your same tools (Tools Unpack System and with SuperR's Kitchen).

Same resut = the system.img is impossible to unpack.

@to ALL :

Is there someone who is able to unpack the system.img ?

Thank you in advance

Hello, developers. I don't know whether this would help, since I am just an user.

I am a South Korean, and I shared this developing issue about kernel with my regional forum of foreign phone users.

They gave me some information about developing MediaTek devices, and if this issue with shell root is caused by kernel it might help.

There are a developer group called MAD, and they handled kernel of a Helio P20 device, Umidigi Z1, thanks to SONY which opened mt6757(P20) kernel to the public.

Although we are dealing with a P25 device, this source might help.

Followings are the links to MAD and the P20 Kernel they had posted. I hope it does help. Thx.

You need method for unpacking system.img, or just files? Can it be just copied from twrp using tar - cp? That is how i make manual backups....
[Android Software Development] Cleopatra Bianchi:
answer

I need a method to unpack the system.img (without using the twrp).

Do you have tried to unpack the system.img with Tools Unpack System and with SuperR's Kitchen ?

I have also tried to unpack the system.img with Tools Unpack System and with SuperR's Kitchen.

Same resut = the system.img is impossible to unpack.

I will say it again : Is there someone who is able to unpack the system.img ?

Thank you in advance.
[Android Software Development] ghost45:
Cleopatra you are welcome..

Of course that the preloader is not connected to the system... But probably your have misunderstood..

I said... That the problem with the flash process with flash tool .. Is connected to the preloader...

What do you want to do with system decompressed?

If you want i will upload the system decompressed...
[Android Software Development] Darkoholic:
Hello. Does the phone get OTA updates?

Have you got any from them?

and when was the latest update you got? :)
[Android Software Development] Cleopatra Bianchi:
answer

I do not want that you upload a decompressed system.img

I want to point out that the system.img of your stock rom is impossible to unpack.

MSD-Amadeus tried to unpack it with Tools Unpack System and with SuperR's Kitchen (post number #108 )

I have also tried to unpack it with his same tools.

Same resut = the system.img is impossible to unpack.

If your system.img is impossible to unpack,

probably there is something wrong onto your system.img

Guys, what's the point in flashing rebuild rom, any changes?

[Android Software Development] ghost45:
New Upload in progress.... Vernee_Mix2_firmware_rebuilded_Ver3 2/12/2017

My presuppositions and doubts were founded about the preloader that have problems ..

(attention please DO NOT FLASH the preloader file in any case )

I have read also in others forums about the doogee and others Mix series that seems clones to its selves and all of them have problems with preloader.

So at this point am not able to understand what is not run correctly,

the file preloader is correctly rebuilded

in comparison to the allocation table written also in first page and descibed from the command adb, fastboot, and sgdisk that have read the internal allocation block of memory and size builded from Vernee.

But according me, probably, there is o are problems hardware connected to this block of memory or, like the CLONES devices, this vernee have Fake data, Fake details that is written inside ...like the Clones Devices.

In this new upload i have adjust, correct and tested (obviously) all the files inside and i make a log review when i finished the ulpoad.

I'm in a closed street without exits so i think this is the last firmware that i i'm able to rebuild in this strange device.
[Android Software Development] Klaus69:
Awwww, please don't ruin our dreams to have a well working device :crying::crying:

At least can you, please, solve the known issues in it(low volume, low GPS and WI-FI signal and maybe the camera)?

Anyway, big thanks for all your efforts.
[Android Software Development] rolandvb:
I don`t understand , i made twrp backups and with flashfire and works flauwlessly, my conclusion is that there must be something in the phone that is not compatable with the flashtool

i think that the proof is you also can not make a readback with flashtool either, maybe the solution will be we send all our phones back bacause they are not giving proper support and when problems occur you are not able to flash the phone to stock , all MTK phones should work with the flashtool it is made bij MTK themselves to be able to flash te phones, if it is not it is in fact a defect product ,if so we should all send the phone back and get a full refund. it is a MTK phone and teh flashtool should work flauwlessly, because it is not these phone cab be considered as phones with a defect. (that is my opinion)
[Android Software Development] Klaus69:
Send it back to China? :) :) :) Who'll pay the transort(hint, chinese sites don't)
[Android Software Development] rolandvb:
I think it will be a lot of work for making a flashable rom because there a problems that mtk flashtool can not handle.

Hope Vernee will post a downloadable original firmware soon, they did for other models to.
[Android Software Development] leongheng70:
[MENTION=4945206]ghost45[/MENTION], don't give up.
[Android Software Development] rolandvb:
i won`t

i will not give up , i know a lot about android stuff but not on at that level i can make my own readback rom, certainly not when it is not working with the provided original MTK tools and

not compatable, because it is giving a error on the mtk tools

that means that Vernee did temper with some files and the cause it does not work, think it has to do with the costomization of the VOS android.

i did download the vernee mars pro rom and looked at the stuctures and is full of patches and is not a normal stock android rom, maybe that is why it is giving problems

with mtk provided tools ,maybe some costimizations in the rom are causing some kind of conflict because they did alter things that way that it is not compatable with the mtk tools

i think they did not followed the official rules to make it work, if you can not even make a normal backup of you`re phone say`s it all.

maybe a hint for developpers working on the device. the problem with mtk tools is that i can not readTotalBytresPerChunck, it says it has a Unknown Rom stucture, i think that this ussue has to be resolved and it will work, how?? i don`t know
[Android Software Development] leongheng70:
this phone display is awesome, but the software really stucks, these few days i have an issue with bluetooth that disconnects frequently when i am either listening to music or talk, oh God am not sure why i am having all these issue, am almost on the edge of tearing my hairs off, and i don't have much...hahaah

If someone can repacks it correctly, i think my issue should solved correct ?
[Android Software Development] fxnoob:
Actually, they want to extract the rom in case of soft brick. So far they didn't modify anything.
[Android Software Development] ghost45:
Thanks to everybody,

[MENTION=1337075]Middelburg[/MENTION] yes propably Vernee don't have pubblished one official rom for mars device from zero start ...but there are a lot of patch and only ota.

Probably the Vernee brand make a customization in their phones and not pubblish for this reason the original firmware .

For vernee Mars i rebuilded two android 6 & 7 but i didn't receive all these problems fount in this new device Mix2!
[Android Software Development] rolandvb:
i think in the rom of others vernees certainly also will contain the original firmware, a few patches and some updates will never be a 1.5 gigabite file right??

my thougts?? maybe there is a hidden script to deploy there own firmware version and this scipt is kiliing ktm tools??

maybe it stock android 7 and a cript is altering it to there own Vos rom , is that maybe possible??
[Android Software Development] MSD-Amadeus:
These problems with the rom, remind me a lot of development problems, with lenovo.

I have seen other brands, which are not lenovo, use these img in their stock rom:

System-sing can see it in vk mix plus.

if it works like a lenovo, you can only install the signed stock.

we hope that they take out the rom stock, so it will not be difficult to install it with flash toll.

What is the problem with TWRP?

Want a compiled one?

I hope my phone arrives soon
[Android Software Development] rolandvb:
As it is so complicated with this phone to get things right i am afraid developpers will abandon the mix 2 development soon quote developper : In this new upload i have adjust, correct and tested (obviously) all the files inside and i make a log review when i finished the ulpoad.I'm in a closed street without exits so i think this is the last firmware that i i'm able to rebuild in this strange device.

now these problems are dicovered it is suddenly also to quiet on this forum alreddy and i am afraid there will never come a solution to be able to flash this rom with mtk flashtool

i think It will take to much work to solve these problems,don`t count on Vernee to give us a normal flashable rom, it will only at the max

a ota update. i hope i am wrong, the best solution will be that someone will succeed to make a android 7 stock rom for this phone and will remove all VOS elements, but this will probably will never happen.

i think i will sell my mix 2 or return this phone to china, it does not work with the official mtk tools and can do nothing with it without the risk of a full brick. if in a few weeks we will have no new news about a solution and further development it will never come ,mark my words, seems the vernee mix 2 development is alreddy dead on this forum :confused:
[Android Software Development] bombic:
Why is my phone restarting to twrp, again and again? Don't know where i go wrong.

Seems I deleted everything on the device.
[Android Software Development] rolandvb:
rebooting twrp

keep the small button on you`re phone pressed untill it shuts down en then reboot,

if it starts back to twrp do the same shut the phone down holding the start button untill it shuts down and reboot

holding the volume + and the start button and you will get a boot option and chose normal boot

if these 2 options does not work you will have to try to restore you`re phone with the files provided (Rom) and try to restore it in adb

hope the first given options will work 4U
[Android Software Development] bombic:
My phone is blank, ther is nothing on it except twrp.

and sp flash tool delivers error every time I try to install with it because as soon as I conect phone to pc it powers up to twrp
[Android Software Development] rolandvb:
if it is blank you have a problem my friend,did you not made a backup in twrp first??? if not and the phone is blank the only solution will be to try to restore the phone with adb with the readback files provided
[Android Software Development] bombic:
I did stupid thing while backuping, so there is no backup.

I need twrp rom to flash it.

Invalid sparse file format at header magi

I allways get this message when try to install system.img with fastboot

I think image is too big
[Android Software Development] rolandvb:
hello i am not a very skilled developper just a beginner and i can`t help you with this problem , i would try things out for you first ,but this will be with the risk of bicking my own phoene and hope you understand i can not take this risk.

the only way to revive you`re phone is falshing teh files troug Adb , if you lost you`re preloader loader i think you have a big chance thet you will end up with a dead phone at this moment.

if vernee does not provide us with a stock firmware that can be flashed with mtk tools, (they probably will not) the`re will be no other way to restore you`re phone.

as you`re phone is in fact alreddy dead at teh moment maybe you can try to flash the hole rom with mtk falshtools, if thsi works this also will mean that ther is also hope for others who did brick tehy`re phone. good luck
[Android Software Development] bombic:
I never used MTK flashtools and there is no softvare to flash
[Android Software Development] zogu:
Just make twrp backup on your device without data partition and send it to [MENTION=4287385]bombic[/MENTION]

With twrp and working fastboot, we don't need spflash tool at all.

My device is waiting for custom clearance, but my country is slow, hope i will receive it in next ten days
[Android Software Development] bombic:
that will be great
[Android Software Development] rolandvb:
that is tue but a lot of not so enlightened users does not know how to work with add, to conplicated for them, it is a MTK phone so it should

work wit mtk tools, now you have to root you`re phone first and install twrp and make a backup ,that means you lost your warrantee !!

what if TWRP , what are you going to do when the mix 2 will not boot in twpr again afther a corrupt flash??
[Android Software Development] zogu:
Please [MENTION=4945206]ghost45[/MENTION] can you make twrp backup of your device for [MENTION=4287385]bombic[/MENTION] and other users, easiest way for restoring device. Or anyone else :)
[Android Software Development] bombic:
[MENTION=4945206]ghost45[/MENTION] give avay his device, so if someone else can send me twrp backup I will be very greatfull
