Need to downgrade the Os from 5.0 to 4.4

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.

[Q] Benefits to a Nougat Upgrade?

The A7U with MM (as I have modified it) has been very satisfactory, but I continue to debate over the upgrade to N7.0.
I did try some early Nougat versions on the old Nexus 5 and a Samsung tablet and ended up reverting back due to various performance issues, but that was a while ago.
Also, some here have reported problems either with the process or with the function of the end resut, so I am looking for some recommendations pro or con about making the move to B15.
Thanks

I'm on N and the only reason im on N is because ZTE fixed the VoLTE and its not roaming on Verizon any more. Pretty much works as it should and acts just like a Verizon device which is impressive, because we never get to play with unlocked devices on Verizon.
Now to the actual B15 stuff. Its a bit more laggy then MM and a few apps are pretty much unusable on N. Those are WhatsApp and LinkedIn on my device. I think I've seen another one or two somewhere else.
Camera is definitely better for me. Battery is great for me but it was great before the update.
Pretty sure im forgetting a few things. Overall im happy with the device and even happier that VoLTE works now.
7.1.1 should be out soon, hopefully that takes care of these few issues.

All of this is covered in the nougat thread.

Seeing a higher build number in About Device

Thanks for your typical, cryptic response. I see lot of ROM threads and conflicting guides, but certainly no "Nougat thread". Can you offer a link?
Regards.

This is the thread that was started when nougat was released.
It mostly covers flashing issues but there is feedback as well.
You can also read the zte forum for lots of N opinions, probably more then anyone could ever need.
Personally I think its ok, but only with custom kernel to speed it up. Hoping 7.1.1 will be better.

Thanks, hadn't seen it & gave it a read. I loaded Stock (rooted) 7.0 and found it fine. Perhaps a touch slower than MM, but certainly no noticeable problems (or benefit).
I had Substratum working 98% (including Android System) in MM so missed the darker theme. Also TB was unable to see its archive on the extSDcard, although worked fine when I moved it to the internal storage.
Also tried RR, but couldn't get Gapps to install over the ROM (TWRP errors: either unsupported device or incompatible ROM errors), so reverted back to B29 for now.
I saved a TWRP BU of B15 w/ all data for a starting point when 7.1 is released.

Stock vs Lineage ROM

Considering modifying stock HTC 10 with Lineage. I don’t use Google. Unfortunately that’s tied to Pay by phone. The only feature I miss. Other than that what benefits do people find going through the root/install Lineage option? Sprint makes it difficult due to firmware, but I can deal with that if there are enough payoffs. Reasons to install Lineage these days?

I love using LOS and it is the pinacle of ROMs for any phone. For Sprint and HTC there are a few different options that you can use with this phone. However if you are new to phone modding and rom flashing, I would approach this topic gently and start with something more fundamental. OMJ makes great stock roms for your phone that you may want to try flashing first just to learn. Moving to lineage os will take quite a bit more knowledge and practice with ROM flashing and phone modding. You will have to have sunshine first of all and you will have to have modded your firmware to go straight to LOS. If you are comfortable with those things, LOS 15.0 for example will take the stock rom size of 3.2gb down to about 450mb for a bare bones aosp stock rom. I love LOS and it is where I want to be with my devices for unbloated roms without any bloat. They are fast, snappy, have great battery life, unlocked tether, and you will reap the benefits of having a bloat free rooted and unlocked device without all that sprint spamware. Using a tool like magisk or xda on a pure android phone unlocks tremendous potential and many options for your device like audio engine mods, theming, gps spoofing, the options are limitless. Let me know if you have any specific questions and I will do my best to help.

Well, I'm not new to flashing ROMs. Would i still be able to use Pay? I realize i'd need a slim version of Gapps. This is the only feature i'd like to keep. I don't use it, have used it and it's quite useful in case i lose my wallet. Know what i mean?

I mean, i've done quite well without Google. Here's my apps...without ever logging into a G sccount.

Well, I've taken the first steps. Unlocked bootloader, Installed TWRP and rooted. Seems phone makers have made ROM installs more complicated these days. What's a good source for getting around the firmware issue on these sprint phones when installing Lineage? Is there a good solid tutorial? I mean, the Lineage OS site is good, but points out the firmware issue and says to search XDA. I can't seem to find a simple tutorial on that aspect. Thx.
Oh, also... I'm no longer on Sprint with this phone. I've had them unlock the sim and I'm on Simple Mobile. Does that make a difference? Is this still considered a Sprint phone as far as flashing goes?

OK, I installed Lineage OS. Weird that Oreo version isn't available. Anyhow. Everything seems to work fine except home button/Reader. Not a deal breaker as onscreen buttons work fine. Is this because I'm on different firmware? I'm on stock Oreo firmware?

Great to hear that your making progress with no hiccups. I'm just patiently waiting for the Pi update for lineage on this device. Now if you want root, you can flash magisk and even start playing around with substratum to do some theming!

Thanks. Does your home button/reader work?
I guess the issue could have been avoided if I'd RUU'd back to N before installing Lineage. Are there any other issues I might have? If not, I can live with onscreen buttons and wait patiently for Lineage on Oreo update.

Well, that didn't last long. I was getting the dreaded password upon entering recovery. When backing up I noticed could not mount data. So I've taken the plunge and installed unofficial lineage for 8.0. Seems okay. Got my home button and fingerprint reader back.

Hahaha

Well, I'm back on Official 14.1
I need my speakers and there are too many crashes for me to use 15.1 as a daily. I do understand that 15.1 is not even beta yet. That guy has obviously done quite a bit of work. Nice to see the HTC 10 has not been forgotten.

Old Lenovo b8000-f, what can i do?

Hi, my wife give the other day an old lenovo b8000-f she had at her work. I't new with little use with use, but of course i can't be perfect i shas android 4.4.2, very old. I don't want to use it as a brand new modern tablet, but with android 4.4.2 i can use it for almost anything. Is there a rom to upgrade it, i already search and i can't find anything. I fanybody know some roms plese tell me.
Thank

Aloha, I looking for any ROM to update my Lenovo B8080-F as well, however, at the moment I couldn't find anything relative to this even on Google. I just found this to Install a Recovery TWRP https://forum.xda-developers.com/android/development/recovery-twrp-2-8-7-0-touch-recovery-t3282520
We appreciate if someone read this and got any idea where can we find a ROM to update our old tables.
Cheers!

Does anybody have a link to a custom ROM for a Lenovo B8000? Seen the instructions to install TWRP but don't see much point in doing that unless there's a ROM available.

I'm looking too. It seems such a shame to let an old decent tablet like this go to waste...

Any way to remain on stock, but get the security updates?

I've use ROMs in the past, but never with the Essential phone. In fact my phone has run so well, I've never even factory reset it a single time, let alone put a ROM on it. But with Essential gone, I need a way to keep my phone secure.
I'm wondering what the best way to keep stock android (nothing wrong with stock) but allow myself to get the latest android updates as they come out. In looking at the ROMs there still seems to be some issues with bugs, and since this phone is my daily driver, I'd like it to be as stable as possible.
So is there:
1) A way to get the PH-1 on stock, but still get the important security updates somehow?
2) A rom available (even if android 9) that works for PH-1 that would be super stable but also get all new security updates?
Thanks in advance for any help.

I could have sworn I saw something that basically said you can download the latest stock version (that includes security updates) and flash it every time there is a new update. But I guess I could have misunderstood?

That was the case until Essential went out of business - you could do OTA updates, or download and flash yourself. The stock security updates were only provided by Essential, and the Feb 2020 update was the last one for this phone...

No way to stay on stock & get security updates (well you will get some direct from Google ie the Google Play System Update, the last one shown lower down this page
https://source.android.com/security/bulletin/2020-03-01
and can be found in your settings under security, but its only a fraction of patches)
That means your best option is probably the Android 11 GSI when it's out of Developer Preview in a July (?) and hope it's bug free, else Lineage etc .... not that you want custom roms, sorry.

Basically I'm looking for something safe and stable, whether it is ROM or otherwise. Right now I'm stable, but not safe. So you think my best bet is move to Lineage (to become safe) and then switch to the GSI when it is out of developer preview (and stable)?

From what I have read and asked here: https://forum.xda-developers.com/essential-phone/development/rom-evolution-x-4-1-69-t4073153
This ROM will give you what you are asking for as far as regular security updates are concerned. I have been waiting for Lineage to release an "OFFICIAL" version of Android 10 for our PH-1's but so far nothing. Also I would not mind going on Android 11 but then I do not think that will get monthly security updates either so I am thinking about trying this Evolution ROM out.... I have never worked with a phone with A/B slots so that is my only concern but after reading all the threads I am starting to understand how that works.
Hope this info helps you out.

I'm the same boat as you, had hoped to flash LineageOS 17 months ago then move to Android 11 in few months time, guess it's decision time now.

Guess for stability & functionality it would have to be LineageOS.
Looks like May version is ver 17.1 (Android 10), not sure how this compares to previous version re bugs/working functions, but that means previous ver is already a month out of date on security )

Also DO NOT use the Essential USB cable & DO NOT relock boot loader!

I'm on EvoX the only thing tht is not t working very well, is tht if u fast forward or rewind on Netflix ur phone reboots, hopefully fixed next update, but I'm happy with this ROM, the touch lag is almost non existence for some reason, glad they managed to fix tht. Also L1 certification is still there. The 360 camera workes better in this Rom for some reason. The best part is the customization though, so much

Very strange that no one has started a new thread in the Custom ROM section about this... (This being an official release version of Lineageos 17.1) you would think it would be bigger news? There is still only an Unofficial thread... strange..
Anyway IronRoo let me know what you decide to do and how it goes... I am still on the fence as my PH-1 is currently working perfect on stock 10 but it is of course on the Feb 29th security patch... plus I haven't done a custom ROM install since my LG G5 but I hear it is like riding a bike... lol :silly::fingers-crossed:

For LOS, I think we should wait until their server is back, and few more releases come out.
LineageOS 17.1 for Essential is so new, only couple releases, and still in updating state.

Yes, many will agree, though I'm OK with giving it a go but I need to buy a new high quality USB cable as kid damaged my Samsung one and have only a cheap 6" one which I'm not sure I trust to flash without bricking phone.

Just did a quick websearch and a few have tried flashing it reddit and here on the 16 thread, and it's suggested wait for next release (first recovery had issue, but now fixed, but next release of ROM should have a few fixes & Lineage build servers are down so not sure when new release will drop)
