First thing to do is to shut down your phone. Press the volume up and volume down buttons and then while the 2 are still pressed, press the power button. Your phone will boot into the recovery mode in 8 to 9 seconds. Once in the recovery mode, use the volume buttons to navigate to the "power off" option and use the power button to select it. This should power off your device and stop further power drainage. Then charge the battery to full while waiting for expert advice...

Is it possible for someone to create a 09 TWRP correctly configured to install rollback or with rollback already installed?

I just cannot get further then 5% when installing rollback. Would be very useful for everyone.

Thanks in advance

Gesendet von meinem HUAWEI MT7-L09 mit Tapatalk
[Ascend Mate 7 General] Blue.Ember:
Before install the rollback give me a screenshot for the location of your device and the model.

There is a reason that's why it's keep falling.
[Ascend Mate 7 General] marcus.linkenbach:
Here it is.

You see, all preparation is done.
[Ascend Mate 7 General] Blue.Ember:
Disconnect the phone from computer then make a restart then reset, then put the rollback into dload on internal storage, turn off your phone and upgrade with 3 buttons.

If it still failed replay to me and we will try something different.
[Ascend Mate 7 General] marcus.linkenbach:
OK, I will do so. As I am not at home, it could take a "moment"
[Ascend Mate 7 General] marcus.linkenbach:
I am very sorry, but it won't work. What to try now?
[Ascend Mate 7 General] Blue.Ember:
Replace build.prop but this time use the one for MT7-TL10 but before that take a backup for what you have now.

And send to me ur email so I can contact with you hangouts
[Ascend Mate 7 General] Mansourkamel:
thanks alot

i done it and it works good thank you but for the file build.pro .... where i put it and in which step cuz my phone is TL10 Jazz
[Ascend Mate 7 General] Blue.Ember:
Downgraded already to 326 or still?
[Ascend Mate 7 General] marcus.linkenbach:
Still won't work. Always the same error.

5% is the end. Several Times I did it again and again. I did it with root Explorer, ES Explorer. Not with FC Explorer. But this couldn't be the reason, could it?

I still can't get my phone to boot up properly. :(
[Ascend Mate 7 General] marcus.linkenbach:
Hola!

As it seems not possible for me to update the rollback in no way I ask again for help by providing a twrp backup in wich a rollback update is already installed.

Please help, because marshmallow is useless for me.

A few minutes after screen off all apps are sleeping and no messages arrive til that moment I switch it on again.

[Ascend Mate 7 General] Blue.Ember:
Everybody please, the method is worked 100% and tested on the both model, MT7-TL10 and MT7-L09, I believe that you are making something wrong and you don't know it, so please don't blame me if you're not make it correctly, read the method carefully again.

If your device is L09 you can ask for support from [MENTION=4190256]chudy_85[/MENTION] he already rolledback from this method.

[Ascend Mate 7 General] stanlawren:
I think doze is messing with you
[Ascend Mate 7 General] marcus.linkenbach:
Yes. I think so, too.

I try everything to adjust. Even with Doze editor. Nothing prevents whatsapp from sleeping? I want my LOLLIPOP back!

But I will be patient...
[Ascend Mate 7 General] stanlawren:
Have you tried making WhatsApp or whatever other app you're having issues with a protected app?

Go to phone manager >>Battery Manager >>Protected apps and turn on protection for the apps you desire.

I think it should work for you
[Ascend Mate 7 General] sanggria:
I got my phone to boot up to system okay. Thank you much to Blue.Ember for the help he has been providing me with.

It is just that Wifi and Bluetooth are not working properly.
[Ascend Mate 7 General] marcus.linkenbach:
Thanks for your reply.

I tried really everything.

Last try was the doze editor.

Am I the only one with these issues?

Maybe my phone is over!?

Thanks and nice weekend everyone...
[Ascend Mate 7 General] stanlawren:
Well honestly I have no idea what really could be wrong with your phone. Keep trying to get back to lollipop.

For me marshmallow ist die beste.

Am never going back to lollipop or kitkat except huawei doesn't let me move from beta to an official version like they did on lollipop.
[Ascend Mate 7 General] marcus.linkenbach:
Which Version do you use? 511 or 513?

Both are not really fluently for me.
[Ascend Mate 7 General] stanlawren:
B511. I actually have the TL-10.

B513 wasn't released for the TL-10 but I've come across people using the TL-09 complaining about a lot of issues. They all said B511 is much better
[Ascend Mate 7 General] tjoseph623:
I do not have root installed on my phone. Since I installed b513, I am able to browse system folders through es file explorer. I can see build.prop file. Would you advise to replace it with the one in forum to change model name JAZZ?

-open fx file explorer and grant it from SU, go to system root and make sure you mount read-write

-copy oeminfo from the extsdcard to /dev/block/platform/hi_mci0/by name and agree for overwrite, after that select the file and choose security and mark for all "read-write-exec"

2. download & install B522 full firmware Then factory reset, everything will be ok,

"-now make a restart but first you should be on official recovery, if you are not turn off the phone open it again on bootloader and flash the official recovery ten restart

-after restart it should make "optimizing"

-after it finish take the roll back and put it in dload on the extsd

-make a local update ( if you don't have it go to dial and type *#*#2846579#*#* and choose 4)

after you make a local update the roll back should complete 100% because this file is the only roll back that compitable with B511

I promise you it will success with 100%"

For me Mt7-l09 australia vodafone version. After restart, the system doesn't show "optimizing" . and the update stuck at 5% then failed. I flash stock recovery but didn't do unroot.

in this step it gives me error. I can not continue with the tutorial.

*************how do it

flash b511 backup

wipe/wipe advance and do it wipe data, cache, dalvick cache

flash supersu v2.64 for mm and reboot

after boot install fx explorer and set su permision

Go to system root/system and edit build.prop

ro.build.flavor=JAZZ-user

ro.product.model=JAZZ

to

ro.build.flavor=MT7-L09-user

ro.product.model=HUAWEI MT7-L09

and save

now copy oeminfo to dev/block/platform/hi_mci.0/by-name/ and set permissiom to 0777

now copy custom bin to system root/data and set permission to 0777

check your region it must be china if you have china reboot to fastboot

Now flash stock recovery ( if you have fail you must unlock bootloader using code )

[Ascend Mate 7 General] stanlawren:
I don't understand your question. You said you're rolling back from lollipop to B331 right?

B331 = lollipop

So why rollback if you're already on lollipop?

Or did you mean to say Marshmallow to B331 lollipop?

If yes, then why are you using the old method?

The method was for the time when there was no official downgrade package.

Now there is an official B500 downgrade pack. Just download and install it for your device and then install the B331.

All those steps you took are unnecessary.

Es ist oft frustrierend, wenn man alle Antworten weiß, aber niemand kümmert sich darum die Fragen zu stellen :|

@Blue.Ember

I apologize, I need to also thank you for the MM to LP downgrade. I originally followed [MENTION=6249201]chuddy[/MENTION] method for 513 to LP, but somehow went down to 511. That's when your post helped me out with reviving a boot looped HAM7 stuck on 511 and then enabling it to downgrade back to 331. I got carried away and assumed the whole process was only provided by one dev, but I realized you were involved as well. Thank You for your post again, it helped bring my unit back to working order!! :good::good::good:
