Hi .

Do you have a source code for your TWRP ?

Thanks :good:

[MENTION=477335]Blackball[/MENTION] When attempting to switch from this TWRP to the one by Tkkg, afterwards I get this screen when attempting to boot into recovery. So I end up having to switch back to your TWRP. How can I succesfully switch wihtout getting this error screen?

[MENTION=477335]Blackball[/MENTION] Thanks, much appreciated! I have one more issue with your TWRP, as it doesn't allow me to flash any .imgs or zips. When attempting to install LineageOS on my Mate 9 (ARM64 A-Only), I get an error message: "cannot flash images to file system twrp". Flashing zips like Magisk, for example also fails with an error message: "updater process ended with error: 1". Any idea what the issue could be?
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Blackball:
You can flash aosp images only with fastboot.

If you wanna flash official Magisk please use my latest twrp from P10plus forum.

Its working with mate 9 too.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] ante0:
First question: TWRP can't flash images to ext4 partitions. You can however unpack this TWRP and edit etc/recovery.fstab.

And add this line (Under the current 'system' line, for example).

/system_image	emmc	/dev/block/platform/ff3b0000.ufs/by-name/system	flags=display="System Image";flashimg=1;backup=1

Easiest way is probably just to boot to fastboot though, as you'd still have to factory reset from stock recovery.

As for Magisk, it's because Magisk looks in /dev/block/bootdevice/by-name/ for 'ramdisk', but there's only ramdisk_a there so it fails.

One way would be to edit magisk installer to look for ramdisk_a, or use the P10 TWRP as Blackball said.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] luyongfeng:
Dear Mr.BlackBall

Good TWRP! Thank you. In "Mount" menu, there is a function "mass storage", I click it, but no any reaction. Theoretically speaking, it should mount the MicroSD card as a removable flash disk on PC.

Would you please kindly make this function workable? For all Huawei devices with EMUI4.1 or earlier, this function is workable. But from EMUI5.0, this function seems not workable any more.

This UMS (USB mass storage function, connect pc and turn Micro SD card in photo to be a removable flash disk on PC) is much better than MTP function. I compared the files in EMUI4.1 and EMUI5.0 (or up),

and found in EMUI4.1 or lower version, there is such a folder "/sys/devices/ff200000.hisi_usb/ff100000.dwc3/gadget/lun0". But from EMUI5.0 (including EMUI8.0), this folder is no longer existed.

Thank you very much.
[Huawei Mate 9 ROMs, Kernels, Recoveries, & Other D] Blackball:
Install a custom kernel. Then you have access to your SD card after you booted into twrp.

[HTC U11+ Questions & Answers] HrBorggreen:
As title says, the backlight started shining through on my U11+. [IMG="Picture of backlight bleed"]https://i.imgur.com/mdG5MUV.jpg[/img]

It happend today, i was on my phone. i put i down to go get something to eat and when i came back the bleed came. it's around the entire screen.

i haven't contacted HTC yet because i wanted to ask you guys and get your opinions first.

i haven't dropped it, i haven't thrown it after somebody. i've been looking after it.

Sorry for the unacceptable quality on the picture, it's taken with my work phone.
[HTC U11+ Questions & Answers] devsk:
That's not good. RMA it if you can.
[HTC U11+ Questions & Answers] jaylo2003:
Did you get yours repaired? My u11 plus just did the same thing today. I am wondering if too much squeezing the edge sense warpped the screen.
[HTC U11+ Questions & Answers] HrBorggreen:
No i Didn't. It "fixed" it self. it's actualy done it a couple of times now and i have never used the squeez fuction.
[HTC U11+ Questions & Answers] DHD22800:
It happened to me too: I was watching a film, checked phone and it presented the same symptom, but in always on display. Rebooted and same problem. After a little time (just 10 minutes or down there).

I am using edge function and it is no longer happened .
[HTC U11+ Questions & Answers] HrBorggreen:
I think the last time it happened to me was in January.

It's a bit bizzar that it comes and goes like that, I still haven't figured it out what's causing it.

But it doesn't seem to be a problem any more so I'm not worried.
[LG V30 Questions & Answers] pisanty:
So with the drawer locked (little button) it's not see through but with it unlocked but on screen you can see through. Why can't I see through on locked mode like on Google phone.

https://imgur.com/gallery/Hrnc5
[LG V30 Questions & Answers] ChazzMatt:
EDIT: SORRY, re-reading for like the sixth time I see I did misunderstand your question. You are only asking about ONE on screen button that is opaque vs translucent -- and the conditions WHY -- not about the entire navigation bar (which LG calls Home Touch buttons) being translucent or even visible. Anyway, hope my answer below this helps someone else!

To answer YOUR question... maybe LG feels that one button being opaque is an easy visual indicator it is locked. Then, unlocked it's translucent. Whereas Google doesn't have such styling concerns.

____________

If I'm understanding the question correctly, and I admit I may not...

It had to do with whether you are in full screen mode or not. Sometimes called immersive mode. When NOT in that mode, you will always have the navigation buttons at the bottom. LG calls them "Home Touch buttons".

When in that mode, navigation buttons are translucent or even missing (invisible). When missing you can swipe up from the bottom to make them appear. They will then appear and be translucent. You might want immersive mode for videos or such.

There's a Settings menu to decide which apps you always want to be in immersive mode. Or you can manually do it by clicking on that very left small arrow button on the by navigation bar (unless you've rearranged the icons). I think you referred to it as "locking the drawer" which confused me.

I really only want video to be immersive. With this V30 tall screen, I don't mind visible navigation buttons at the bottom.

I found this issue because my corporte email app, called Nine, didn't have arrows at the bottom for me to go back easily. I could swipe up and force the navigation bar to appear, but other apps were not that way. Sort of irritating. So,I found the Settings menu with all my apps listed, where Nine had this "feature" enabled. I disabled it for that app.

This may not be exactly what you're asking about, and if so then I apologize.

Ah , we all know miui 8 beta 6.7.21 had a feature called app invisible to hide apps installed on the phone. but later on it was removed .

I downloaded the whole rom package and search every corner of the rom but couldn't find any such app in the rom package . Perhaps it seems , it was some kind of coded sort of thing which I am unable to understand . If anyone of you could help me to have the feature again on my miui 9 beta , I would really be thankful (not only I , but many other redmi 2 prime users too want the same .)

I am ready for any experiment to be done on my redmi 2 prime for that feature . (except that I can't move out from miui rom).
