[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] iamsiddharthmall:
I found a workaround for this (kinda). Not sure if it will work for everyone. So I just logged out my google account from the device. Settings>Accounts>Google - remove account.

Then opened playstore and logged in. And this problem was solved. A similar thing used to happen when I flashed MIUI a few times. If I searched for an app, play store showed me all apps but the one I was searching for. I used to follow the above procedure. My guess is it has something to do with multiple device logins, as in logins when booting a rom for the first time. I would also suggest you open your gmail from some other device and approve the new login (review login activity). Hope this solves it.

Latest build impressions

Battery life has become amazing. From screen on discharge of 16% per hour to 7%. Drastic. Had 4 small magisk modules which I have disabled after updating. That shouldn't make this big of a difference should it?

Bug

Although I have show all notification on lock screen enabled, I just see app icons whenever a new notification comes.

Battery temp is currently 47°c after 25% charge from 40 to 65.

[Touch Cruise ROM Development] gbds:
First i would like to say hello,

and secondly i would like to say that this is my First XDA and i apologise in advance if i appear a complete n00b! But hey that what i am!

I finally made the plunge to go for Orbot 2 which is why i am posting in this forum since from my understanding it is a polaris ( correct me if im wrong)

reasons for change was that i have tried lots of so called smart phones and just not found one that i am completley happy with, mainly the e90, most un reliable wifi and gps ever! and have been using a SPV500 for about 3 months and still love it, its 5 years old (feels like it) and still is probably hands down the phone i rely on the most! and new HTC phones still built like a bunker?

anyway to get to the whole point of the post! (finally i hear you say)

So since im new and not knowledgeable in xda things as of now i have a few questions,

1) ive download all the SPB programs and menus, are these worth it?

2) and killer programs that i shouldt be without? browser, games, themes etc

3) ive read loads of reveiws and mostly positive, the one thing i read was that the 02 formware is sloppy since the video drivers dont work too well, Is this true? if so can i replace them and speed it all up?

4) when i tried using tomtom on me E90 here wasnt support for internal gps receivers, is this still the case? is it worth getting tomtom and ditching copilot?

5) shoudl i use a silicon case or is the phone housing good enough to avoid scratches?

if you could answer all or some of these it would start we off on a good foot!

also any advice will be warmly received!

Thanks in advance

HARD-SPL

Welcome to xda-developers

First of all to do whatever you want you should HARD-SPL your phone.

HERE IS THE LINK
[Touch Cruise ROM Development] sumitescp:
The case that comes with the orbit 2 (uk) it is pretty good that is what i use. However if you want to protect it with a higher level of protection, silicone case will do the job. I don't use it because of my car mount, the phone will not fit on the car mount that comes with the orbit 2.

[Android Q&A, Help & Troubleshooting] indestructible master:
Install custom recovery, make a backup and give it a try.

But dont expect it will work, because of diffrent hardware drivers.

If it doesnt work you will end up in bootloop.

If you dont know what is it, first read some posts about bootloop, how to cure it, and bring back stock ROM again
[Pixel C Q&A, Help & Troubleshooting] bosscharles:
Hi all,

I purchased a job lot of 9 faulty Pixel C's with the usual issues, screen, touch not working, etc.... and have managed to get one going. Sort of.

I foolishly sideloaded the very latest stock Rom dated June 2019 (ryu-ota-opm8.190605.005-079b7ec4) on it without realizing FRP was enabled on the device! So when I power on it says it's been reset and needs the right user etc....

Javascript is disabled on the latest build so the youtube workaround to disable FRP is not possible. You can't gain access to a google chrome browser window. I tried downgrading to an older stock rom but that didn't work....

I'm now trying to get adb/fastboot access but unfortunately USB debugging is disabled. Can anyone tell me how to enable USB debugging from outside Android?

Or is there a way to enable usb debugging on a stock rom and then flash it back on my device? Any advice would be greatly appreciated. Ultimately I want to get it running again.

Many Thanks.

This is the only solution for me right now since I'm talking from my Athena in a loud environment and sometimes from the streets...

It would be great if someone from France could buy it and then sell it to me through Ebay... of course with something extra for his time...(if you ask for too much I might get a secretary as well... :) )

If someone wants to help lets set the price, I need 2 off these (just in case), and let's do it!
