Hey guys,
I need a bit of help here.
For some strange reason I'm unable to install various apps from the play store like Antutu benchmar, AcDisplay or even unable to update The Google app!
I've cleared the cache of the play store and have rebooted the phone but still the same ! What else could I do?
Edit: after another reboot the system optimised itself and the problem is gone! Weird! Anyway is good now, even the screen turns itself off whereas before it wasn't doing it!

That's how it started to work here, after more reboots it failed completely.

The same thing happened just now. I couldn't install an app from the play store. Had to clear data and reboot. It's OK now.
I also find that the battery drains fast. I started the day with 100% and is not even 4pm and it's down to 39%! Nothing like the reviews I've seen saying that the battery should last 2 days!
No doubt that the OS has quite a few bugs.
I'm starting to miss my old Nexus 5 ?

thanks Alberto..

unfortunatey only with adb you can enter in Twrp recovery..
btw it will work for root and backup purpose..

How did you get twrp? When I was looking to flash it, the only info I could find said that you'd need to build it for this phone yourself

A new OTA Update has been released by Ulefone (20160505), it seems to fix all instabilities but i'm not sure. I'll confirm it after some days of testing.
In the meanwhile i recommend you to update your device in order to get as much as possible feedbacks about it.

If they do not release the 20160505 Full ROM then yes, you need to wait an OTA update.

OK, thanks for your help and thank you for this thread and all the support. It's really appreciated! :good:

I wonder if anyone else has received the update?
I'm having lots of problems with this phone and I don't know who to contact to report them so I'm going to list them here in case some of you are suffering the same problems:
* I don't get a 4G signal despite this phone being compatible with band 800Mhz and that's the band my telephone supplier uses.
* The finger print scanner doesn't always work.
* I have to reboot the phone often because I get an error when trying to install apps.
* The battery life is very poor considering its size. I'm unable to get a full day's use with one full charge and I don't play games!
* The screen comes on while the phone is my pocket.
* The phone overheats often for no apparent reason.
* I get a network error when I try to send a feedback using the OTA feedback form.
* Maybe others that I can't remember now.
In summary, I'm a little disappointed and frustrated. . I hope that the update comes quickly and is able to fix some of these problems!

That gives me hopes! Thanks!

Love the walkthrough style. Thanks for writing this up.

Taking the dive later this week, I have been missing root since moving to QAA. I will try to update over the weekend.

Worked!
Everything worked like a charm. I was already on nougat. followed instructions from step 2 and everything is working. I did have to run root.bat twice to get supersu app to show up, but it was already stated in directions which helped greatly for me not to freak out at that point lol. Anyways as i stated it worked like a charm and anyone on the fence if you rooted before you will be able to do this for sure. Once again thank you very much good sir!

Thanks for the root method I have been waiting for something to come out can't wait to try.
And just a heads up it is frowned upon on XDA to share paid apps.

About to attempt, will post results

How is it running? Smooth? hot?

Im guessing its a package i disabled or didn't disable so it will take a bit to sort out. Its no biggie i might need to reroot. I can still raise the volume if i press volume down and move the slider. This is the only minor problem I've seen.

Does anyone know where I can find the nougat firmware? Trying to start fresh after a not successful root. Thanks

If that's the case I would suggest starting over...But just data? Can you call or text? Bluetooth?Hotspot? Is there an LTE symbol in notification bar with no data? Or is it just bars with no service completely? Double check your package disabler.

Try clearing google play store and google play services cache, if there is little cache then clear data and reenter your gmail. Youre talking about when updating in play store right? If not try only disabling these below instead [from goongydin's thread] and flash engineer. Or manually disabling from list(dont import). But once we disable these apps and flash boot img, these apps aren't supposed to change status which would mean repetitive testing. My honest answer is always going to be try from beginning again.

New firmware B389 for FRD-L09

In Firmware Finder is new ROM with build number 389. Unfortunately, no flashable

Hopefully that means that they will release an update soon

Please stop creating new threads for every non flashable update.

I noticed it too...hope they'll make some of it flashable someday... a lot of updates and i'm stuck on B380 lol.
P.s i know that B381 is avaible and flashable but i don't know how to do it. First time with Huawei/Honor device xD

And if you're running TWRP 3.1 just flash the zips from there. First the update.zip, then the hw_eu one, and then flash supersu for root. https://forum.xda-developers.com/p9/development/root-supersu-2-81-emui-5-t3612258
That's how i upgraded from B380 and it works perfectly.

This method don't require twrp or root, this is the same process of the original ota upgrade application, but in manual mode.

Disregard this comment, posted to wrong thread.

hi
Can someone explain me, why is there this kind of update published, non flashable one? internal testing purpose?
Is there a way to update my phone to b389, b388 or other, more than b381, with or without root, even if I have to factory reset my phone, reinstall stock recovery?

You just have to try reading. This topic here and more ...

Hi guys, i've update correctly with twrp to B381 (forgot to flash supersu so...no root. Lol) but i have a problem. On B360 in "Smart assistence" I had the function "Smart Key" to choose ehat to do when the fingerprint key was pressed. Now, after this update i have no more this function. It doesn't show up, even if i try to search it. It has been disabled or should i try to factory reset?

Bypass Lockscreen

My friend uses Honor 6X. He is on stock Nougat ROM. He is no more now. Is there a way to bypass his phone's Lockscreen without losing data so we could get to know some details we need?
*And his phone's bootloader is Locked.
*No way to enable developer options.
*Can i boot into fastboot mode and using adb commands can i boot via TWRP temporarily?

Since the bootloader is locked, the only thing he can do is factory reset.
Don't forget to remember which Google account he used, as it will be required after the factory reset

Possible to downgrade official to official?

More specifically... Is it possible to downgrade from Official Pie back to Official Oreo?
There is no fault with the Pie OS itself. It's all about various preferences that are no longer available with Pie, as I do not wish to root at this time. Pandora lockscreen controls, the use of Substratum, expanded volume controls, to name a few.

Yea, that didn't work. Someone else mentioned a rollback ROM that could be used, but I am having issues finding it. I'll keep searching, unless someone else has done this already and is willing to chime in on what needs to be done.
Thanks in advance to anyone who replies.

I had problem using the rollback package... Device had been encrypted and no PIN accepted. So i had to do a clean install.
If thats ok for you just follow the steps here and you are back on OOS 5.1.5

Yea, that didn't work. Someone else mentioned a rollback ROM that could be used, but I am having issues finding it. I'll keep searching, unless someone else has done this already and is willing to chime in on what needs to be done.
Thanks in advance to anyone who replies.

That's exactly what I did... Flash the full ROM, flash TWRP, reboot recovery, flash magisk. Disable lock screen before you do anything.

It's a security patch/encryption issue. I believe you have to format (not just wipe) data. Then you should be able to install the stock rom.
Note that everything on your phone will be wiped by this, so make sure you're backed up externally.

Thank you all for the replies so far. To clarify, I'm on stock Pie and want to roll back to stock Oreo.
Full wipe, etc. is perfectly fine by me, as long as it's possible.
