Need to downgrade the Os from 5.0 to 4.4 - Nexus 7 Q&A, Help & Troubleshooting

Hey there, I've recently bought a Nexus 7 with the latest os already installed on it, which has made it run slower with every passing day.
I did a bit of googling and found that a lot of people had issues with their Nexus 7s after they upgraded to the latest os.
So now I'm wanting to downgrade to the previous os and I read in an article on Androidcentral that said getting a custom rom would be the best way to go to (I'm guessing) either get a previous os or get a streamlined version of the one I already have.
So I need help finding the best rom for my purposes, I'm very new to this sort of thing, in terms of roms,flashing and downgrading os and such so any help would be greatly appreciated, as I'd love to be able to use this tablet St something other than the speed of smell lol.

@EddieHades welcome to the community. First of all it's always the best method using a custom ROM, but make sure you have unlocked bootloader. If you don't have unlock bootloader then you've to do it first, make sure you've backed up all your data. Second choice if you want to stick with stock rom. Then just go to this link and download your preffered stock ROM as per your device, make sure you've downloaded proper images. Then download Nexus Root Toolkit and flash that image and you're good to go.

New user on xda-developers needs help..for finding/installing andriod 4.XX

Dear All,
Im a brand new user. Can somebody help me out...I have a Samsung Galaxy Tab 10.1 wiffi...
I managed to rooted my device successfully ..now I’m looking for a stable android 4.XX with the capability to charge the tablet when connect on pc or laptop via usb. It it possible to install android 4.XX without losing all my installed apps?
I t would be even great with a good instruction how to install it on the tablet.
Can somebody guide me in the right direction..
King regards,
Gevonden
You should really do some searching - the search function will be your best friend. Assuming you are rooted and have a custom recovery installed, I would recommend installing AOKP from this thread and giving it a try.
Again, I would do some searching and READ A LOT. Not everyone is kind when it comes to random posts spamming up the forums.
:laugh:
Well aokp it's a really good rom but you should take into account the fack that the camera it's not working on any ics rom at the moment.
As for your question about the apps i find out that the best way it's to make a cwm back up and then using titanium back up pro (you have to spare some bucks) restore the apps + data that i want from the back up. Also you can make the back up using the free version before flashing the new rom.
Cheers!

[Q] Where To Start

Currently I have never even Rooted a Android device before and I have been wanting to get a custom ROM for awhile now. I saw OmniROM on Android Authority and it looked really good and supports the Nexus 10 along with other devices. I learned recently that it is recommended that you should do all of this as soon as you get the device so that you do not lose information that you might want.
I'm looking for a good tutorial and some recommendations on what I should do to back up some of my files and what I should do in case I decide to switch back to stock Android.
Any help would greatly be appreciated!
This ROM isn't really ready for general consumption yet... it will get there tho.

Installing TWRP and custom ROM on d802

Hey guys,
I have a LG d802 phone which a relative asked me to update (i.e install a custom ROM) because his version of Android, 4.4.2 is having its support dropped for different, important applications he uses and he would need to throw this perfectly healthy phone away otherwise.
I am no expert at Android rooting, but I know the basic idea anyway. However, when I look up this device on TWRP.me (as well as their official app), it gives no results. I find it strange that the international variant of this phone would be unsupported; especially since I have seen threards on XDA as well as YouTube videos posted about running TWRP on this device. I am reluctant to try flashing files from random Dropbox (or similar) links however, especially if they are a few years old.
Could someone please provide an explanation how I go about to flash TWRP on this device, and if there is any special rules regarding installing a custom ROM (in my case, ResurrectionRemix) and GApps?
Also, I understood I need something called "loki", what is this and how do I use it?
Running Android 4.4.2, everything in stock except I enabled USB debugging.
Thanks a lot for any assistance!

Newbie here + require a fast updated rom to flash??

Hi all,
I have not been here in yonks but I know this forum is always helpful. I am trying to flash a slim updated rom on my old android galaxy note. Out of no where, so many of my apps on that phone stopped working and it kept saying, this device is not compatible etc. I tried all the tricks and still a lot of apps will not work.
I have Odin pro installed on the phone but I forgot how to use it lol so may require direct instructions. But can someone recommend a fast but small in size build to flash which is updated. It says on my galaxy note that it’s running 4.1.2 which is jelly bean. If I recall it’s probably a custom rom but it’s been so long.
Thanks I advance if anyone can help me with instructions, I know it’s easy to do, but it’s been ages.
Cheers [emoji106][emoji106]

I need to urgently upgrade from 6.1 to 8.1

So, the Quebec government here has come out with a vaccine passport which will be needed to do just about anything. Therefore, I will need to upgrade the wife's S5 to 8.1, from 6.1, as 8.1 is the minimum for this app to work. This goes into effect September 1.
Now, I see a bunch of things online obviously, but as I recall this place here was/is the holy grail for cell phones. Just hoping to not have to buy a new phone as our pensions don't leave all that much wiggle room.
Note that I just need the stock rom for 8.1. Not looking to root or other such things.
Model #sm-g900w8
Just need to be pointed in the right direction is all. Once I know a source can be trusted I should, hopefully, be able to take it from there.
Thanks.
Well, I do need to try anyway, otherwise I will absolutely have to buy a new phone, which I am trying to avoid if possible.
Thanks though.
Had replied to you in a different thread that didn't have as much info as above.
Unfortunately there is absolutely no chance of getting a stock 8.1 rom on the S5 they stopped developing at 6.1
Best bet is to flash a custom rom like LOS or mokee both trusted roms. But you'll need to flash a custom recovery TWRP.
But yeah Unfortunately that's basically your only option without upgrading the device for a newer model
Good luck

No worries, glad you got it sorted eventually
You're going to get a better experience with a newer phone.
https://play.google.com/store/apps/details?id=ca.quebec.vaccandroid&hl=en_US&gl=US App says 5.0 and up. No need for 8.1. Maybe you should read before panicking.
Hi, you will find all you need to upgrade to Android 11 here: https://forum.xda-developers.com/t/...g-galaxy-s5-from-stock-to-android-11.4354951/
