[Android Q&A, Help & Troubleshooting] CuriousNewbie1:
I have an enterprise device (TC 70) and have just upgraded to Lollipop using the image the manufacturer provide. In recovery mode I see the error: "e: failed to mount/persist" in recovery

I'm now without wifi / bluetooth for which they provide zip files for, and they run successfully, but I'm still without wifi. I'm assuming as it's to do with the persist directory as the mac info is stored in there.

There's a page I've found: https://xdaforums.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576

Is it possible to fix this unable to mount error without root as the bootloader is password protected?

So just got the Unicorn Beetle Pro today for my Note 9 and it has a horrible rainbow effect withthe built in screen protector. On my old glass screen protector is was just a little rainbow effect in the middle. This one is causing the effect on the whole screen. Anyone else have this issue?
[Samsung Galaxy Note 9 Accessories] N1NJATH3ORY:
Rip that cheap plastic off and use a regular screen protector!! That one that's built into the unicorn is cheap A$$ Plastic!

Just remove plastic screen protector and use tempered glass full glue covered, its very fix with bettle pro

So a few days ago I changed my battery for my Honor 8 phone, but after that my fingerprint stopped working. Not even the button is working now, I can't even go to fingerprint management because whenever I try it just kicks me out. I can't get into fingerprint management. Someone recommended me to format the phone. Are there any other options?
[Honor 8 Questions & Answers] PalakMi:
Did you make sure that the fingerprint was put back correctly after changing the battery?!

(I mean the fingerprint cable that connects to the motherboard)

[OnePlus 6T  Accessories] ogkillergreen:
Got this case a few days ago. Design is beautiful. If you have a skin, the clear back shows it off nicely. Back plastic is really hard. Feels like glass almost. You can tell it's a high quality case. It does not feel cheap and my phone feels protected. Great front bezel/lip rise. Power and volume buttons are clicky which is always nice. Ultimately it feels great in the hand.

A few things to think about though.

Since the back is clear hard plastic that means it is a finger print/dust magnet. I constantly have to wipe it down. Also I placed it in my pocket for 10 minutes and I guess moisture caused a pretty big rainbow spot on the back.

The sides are smooth so it doesn't have the best grip. It can slide out of your hands if you aren't careful.

Although the buttons are clicky one thing that isn't too great is that they are flush to the case and the groove indicators are not that deep so more times than I'd like, I see myself lowering the volume when I wanted to increase the volume.

Lastly it adds bulk, but not on the level of a rugged style case. I also have a Spigen Liquid Air case that is just a tpu and this Supcase is noticeably bulkier and heavier.

But ultimately it is a case I would recommend. Dropped my phone on tile floor and of course the phone was fine but the case didn't have a scratch on it.
[OnePlus 6T  Accessories] OhioYJ:
I've ordered a few cases, including the official OnePlus bumper case, and the SupCase is the one I like best. It's been on my phone basically since I got it. As you you mentioned the only real downside I've found is the volume buttons, it's hard to tell which one you are pushing at times. Other than that, a great case, at a great price.
[OnePlus 6T  Accessories] kickenwing13:
Got this case as soon as I got the phone. It's gorgeous, it's protective, even saved it for me nasty spell. But I would safe because of the buttons being flush it's hard to find them really easily. Other than that it really has been an awesome case, thanks to everyone for recommending this case.
[OnePlus 6T  Accessories] dermotti:
I agree with this review, good points and bad. Great case overall.
[OnePlus 6T  Accessories] jananan:
i recently bought this case too

- i like that the flush side buttons don't get caught up when taking it out of my pocket

- and yes kinda hard to identify the vol up and down buttons sometimes - maybe a raised ridge in the middle of the buttons would have helped to tell them apart

- the sides have a slight rubbery feeling - not very grippy but still acceptable - it might appear slippery if your hands are very dry

- moving from the original tpu case that it came with - the extra bulk is noticeable but does not hinder usage unless you have small hands - it is a tad bit harder to reach the top parts of the screen

- i still have the protective film at the back of the casing on - LOL - so i can't tell how smudgy it is going to get

now my question is - what tgsp are you guys using ? i am still on the original film protector that came with it and want to change to tgsp but not sure which one will fit nicely with this case.
[OnePlus 6T  Accessories] OhioYJ:
Any should fit fine. I'm using the official OnePlus 3D one on mine. I just put a SuperShieldz 3D one on my friends 6T with the case a couple weeks ago. She hasn't had issues either.
[OnePlus 6T  Accessories] strictlyphat:
I tried this one on op6 and couldn't live with the buttons.

Hi, all!:)

Simple instruction how to install AOSP rom. Plus overview and feedback, i hope)

First, you need:

1.1. basic knowledge how to using ADB, fastboot and recovery

1.2. clean flashed 9.6.11.0 stock rom

Files:

2.1. TWRP for daisy (official or patched by me for external SD-card and UTF-8 support)

2.2. GSI v110 AOSP rom for arm64-ab (gapps and vanilla variants tested by me)

2.3. attachments

Procedure:

3.1. format you DATA with recovery (!CAUTION! all files from internal storage will lost!)

3.2 on the PC unpack *.xz rom archive to system.img with 7-Zip archivator

3.2. connect phone to PC and go to bootloader mode

3.3. flash unpacked rom image:

fastboot flash system system.img

3.4. when done, run TWRP:

fastboot boot twrp-3.2.3-0-daisy.img

/or fastboot boot twrp-3.2.3-0-daisy_zero.img/

3.5. in TWRP mount /vendor partition and run on the PC (this fix for disable ForceEncryption):

adb push fstab.qcom.txt /vendor/etc/fstab.qcom

3.6. in TWRP mount /system partition and run adb:

adb push uinput-goodix.kl.txt /system/system/usr/keylayout/uinput-goodix.kl

this fix tuning fingerprint gestures: swipe from left2right is "paste-text-from-buffer", swipe from up2down is "wakeup-screen"

3.7. unmount partitions and reboot to system from TWRP. all done!!!:fingers-crossed:

Ok I successfully installed and tested it, everything is working as intended but what I'd like to know, what is the difference to the latest Stock Rom?
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] eremitein:
well good!

this is a pure AOSP android, it was created to be simple and work quickly and without problems))

in stock we have a lot of crap. in recent stock versions after update sometimes system are broken. did you have problems on the Pie stock, no?)

and I ask you to check in AOSP whether the camera starts up in "Do not disturb" mode. thanks
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] cd492:
Sorry I already flashed PixelDust again and didn't test the camera in dnd mode.
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] kftX:
With all due respect, no one should flash GSI roms. No matter how cool it is, they are unoptimized and don't receive any updates. I was on a GSI rom for the longest time and never once was it updated. Which means you'll be behind on security patches, which unfortunately, is rather important.

Project Treble is a failure. Good tutorial for those willing to risk it tho.
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] nehuy:
So, if you don't care about security updates it's a win?

The only reason people search for other roms is because of the features they have.

Also, good maintainers update their roms weekly (or daily for betas)
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] eremitein:
man, stock version for our device had sec update on the 17-th or 18-th january.

phhAOSP released january 8.

so, which version is better supported?)

and more important - after stock update many people have very huge problems.

i'm search a good GSI only because stock version not good
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] Voodoojonny:
Yeah, keep doing this!

I used havoc for a long time, but in the end bb was too bad, compared to stock. RR7 is much too laggy, and freezes and sometimes has no incall sound...

What we should do is focussing on one or two gsi's and modifying everything, sothat it will run on our device properly.

Under QA section there are many solutions for those problems. We only need to put them all together in one thread, connected to the right gsi...
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] cd492:
I tried almost all GSI Roms and the only Rom which satisfies me is the PixelDust for Daisy. Only the notch isn't perfect but that's not so important.

The Stock Roms are a now go for me, I can't even swap the nav buttons and I don't care about security updates at all.
