[Q] Help a complete noob flash Nex 7 please ;)

HI All,
Long time lurker
I get a bit overwhelmed with rooting / flashing and such but yesterday i received my RMA Nexus 4 and decided to give it a crack as it was a fresh start.
Used CF-Root on my Nexus 4, then i flashed Paranoid Android (v3) using Rom Manager (both excellent bits of software and really easy to use) i was so impressed with Paranoid Android (love the tablet mode) so decided to give it a go on my Nexus 7
Used CF-Root again and unlocked boot loader and rooted ok, installed Rom Manger and booted to recovery but it gave me errors when i attempted to load Paranoid Android so i exited and now back just stock software.
I used the same ROM for Paranoid Android that i used for the Nexus 4, i wasn't able to fine a specific build for the Nexus 7 so assumed that they use the same ROM? i now think i was wrong but cant find a specific ROM for my Nexus 7
Would someone be kind enough to tell me if i do need a different build for the Nexus 7 and also if i need a different GAAPS download?
Thanks in advance and sorry if this has been posted before, so much conflicting information and out of date links around the web, i just wanted to be sure.
Cheers
Steve

All I did when I got my Nexus 7 was downloaded the Toolkit http://forum.xda-developers.com/showthread.php?t=1809195
Use that and run the "All-in-One" unlock,recovery,root,busybox etc.
Note: Technically all you really needed was a custom recovery to stick and you can flash a custom rom, but I like to run the All-In-One just in case.
As for the rom, you should not flash another device's rom. Only use the one designated for your specific device. Flashing another device's will likely brick/bootloop your current device.
To make things easier, think of it like this:
Custom Roms likely already have root privileges, so flashing them automatically gives u root access. In order to flash a custom rom, you simply need a recovery like CWM or TWRP. You can achieve that however you like, but the Toolkit is easiest in my opinion.
When you flash a rom, read the requirements on the thread. It should be as easy as wiping Cache/Dalvik/Data, Flash Rom, Flash GAPPS, Flash Kernel if you want to, Flash Multi DPI Play Store if you change dpi of your apps, then reboot.

Paranoid android thread of nexus 7 is HERE, ROM is available for both grouper and tilapia.

+1 on aria807. Nexus toolkit is great for beginners and is very error proof. I've since moved onto fastboot and abd command line, but I still use the tool kit to restore to stock because its fast and easy. Damn program even downloads the images for you.

Dumb question about mix Build Numbers

Well i am a fresh Nexus 6P user and come from Samsung with custom roms and etc.
What happend if i mix build numbers for my Nexus 6P? An example..
i go to google dev and downloads a build that is ex. NRD90U and my Nexus originally use MTC20F.
What will happend if i flash NRD90U? Does they contain different radios? Can this fuc* up OTA? Break warranty?
I have searched around on google what is the downside by mixing build numbers. Is there any? This it totally new for me..

Go here. You need to do a lot more reading before you try anything.

If you flash the newer build it overwrites the older one. You might benefit from looking at my guide:

Using MM ROMs on Nougat firmware?

I've flashed Nougat bootloader,radio, vendor, etc and currently I'm on Benzo. I was wondering is it possible to flash a MM ROM on nougat firmware. Will flashing a MM vendor IMG on nougat work?

Yes to question #1. Radio and bootloader can be used interchangeably.
No for question #2, your phone will not boot if you run MM vendor on N rom. The opposite also applies, N vendor will not work on MM rom.

I'm content with MM right now (addicted to xposed) but if you want to run both you could head over to the MultiROM thread. A couple of users said they're using N as the primary rom and MM on secondary. Then I believe you can swap secondary to primary. Just a thought.
***of course this involves some research. I've been using MultiROM since last spring with no issues at all but haven't tried N yet.

So if I update to N I can't use the pure Nexus ROM?

In short, if you want N & you want to run Pure Nexus you should sit tight. PN will be updated to N soon (hopefully this weekend).
This will be the simplest way. You can always go back, its just not always convenient (using pc or mac with fastboot)

Not sure...where do you wanna be? AFAIK theres nothing wrong with N. Only reason Im not there is cuz xposed hasnt got there yet. If youre content, stay there. Like I said, keep checking the PN thread to see if the new build arrives.
If your asking me how to go back to MM, Id use fastboot and flash the factory images (go to complete stock) start over, flash twrp, root then flash your preferred M rom.
Its a bit of a hassle but in the long run youll have less hassles (bugs and whatnot)

I'll prob just try to find a decent N ROM. Right now As long as it has hotspot working I don't really care what ROM I'm on. Hopefully the N Roms have it
I appreciate your help bro!

no problem. And like I said. Keep checking the PN thread. If youre staying on N it's probably gonna be the gold standard for 6p roms
Update--but if you want a suggestion I think WETA is good. It's got all the sound mods built in so you don't have to flash Viper, Dolby atmos etc.

Please help upgrading Nexus 7 stock 4.4.4

About a year ago I was going to upgrade my nieces stock Nexus 7 wi-fi tablet on 4.4.4 but come to find out there was some bug in the OTA update that would brick the tablet. You had to jump through a bunch of hoops to update it like factory reset. Once my niece heard erase she didn't want any part of that. Fast forward to now and she got a fitbit type device and the software isn't compatible with the current version of the OS. So my question is...Is that bug fixed so I can take the OTA update now or do I still have to jump through all those hoops to do it? If I do have to jump through the hoops then how do I do it? Thanks in advance for any help you can give.

I did update a few days ago and it was ok untill it was time of the 5.1.1 update - brick, so I downloaded nexus root toolkit to get it quickly done.
Make backup using gmail or just root using nexus tool, backup with titanium backup and update to 5.1.1 or custom without worry

Ok so I root with the tool and then flash the 5.1.1 rom or do I have to go up in order?

Go to settings, about device, updates and install all the way up to 5.1.1, it might be a few updates. If the error shows then just use toolkit to recover nexus from soft brick and that's it

Ok I used the tool and flashed the 5.1.1 stock image on it and relocked the bootloader. Now it is very laggy. Anyway to fix this?

The stock 5.1.1 image makes the Nexus 7 really laggy, even when running the ParrotMod fix found in another thread.
My recommendation would be to run Pure Nexus ROM by GtrCraft (links are in the Download section for ROM and GApps, which you need for Google App Store and services). Of course, use the Nexus Toolkit or TWRP as the easiest ways to flash.
Then, flash the ParrotMod fix by parrotgeek1 to help speed it up.
Once all done, it should be as fast as it will get and you won't have any updates or OTA updates to install. Pure Nexus ROM has SuperSU in it, so it will be rooted. Some apps will not work when rooted, so keep that in mind (mainly banking and some streaming apps).

Well I would rather not have it rooted if I can help it. I don't want my niece getting into anything a messing it up. I have read that the marshmallow pure aosp is much smoother or was that what you were talking about? Can I flash that with the nexus tool? I want to keep everything buttoned up for her.

You can use tool to flash recovery TWRP, then boot recovery copy rom aosp or slim or whatever you like, flash it and you're good to go. It'll take up to 15min.
Just read rom description and follow install instruction

Sorry for my ignorance but if I use the aosp rom I would have to keep it rooted or no? When I updated to 5.1.1 I just unlocked the BL and then flashed 5.1.1 and then relocked it. Should I have installed a recovery? I didn't think I should since I didn't want to keep it rooted.

There really isn't anything to mess up when the tablet is rooted. It mainly just gives you access to more settings and more customization.
If you are dead-set on using a non-rooted ROM, you could also use CyanogenMod, which is updated regularly.

This is great but is there a way to uninstall it (if necessary) and get back to the primary ROM (stock or Lineage OS) without losing data?

tried to do a bit of light research and couldn't find what's different between this and other preexisting multiboot solutions. I've been using Dual Boot Patcher for sometime without issues. Is this somehow better? and if so, how?

EFIDroid is what you would call a "second-stage bootloader". The main advantage over Dual Boot Patcher (at least for me) is that you no longer have to patch zip files before installing. Also, EFIDroid is more than just a multi-boot solution. Quoting @m11kkaa:
efidroid tries to focus on simplicity, and doesn't require any kernel modifications etc.
in general: well having such a powerful bootloader in your boot stage gives you lots of possibilities, like multiboot, replacements/additions for kernels/ramdisk/cmdline.
This project has a lot more potential than what's currently implemented. i.e. you can give samsung devices fastboot and sony devices a standalone recovery. Also you can natively boot GNU GRUB if you're into booting linux kernel's the desktop way.

The two solutions are similar enough that you can migrate your setup from Dual Boot Patcher to EFIDroid without losing any data. I'll try to post a guide later this week.

I was I under the impression dual boot required multiple ROMs running the same kernel... If that is the case a huge advantage efi has is each ROM having their own boot img. I'm currently running 3 ROMs a lollipop a marshmallow and of course a nougat. I really just wanted to see all 3 latest android os running flawlessly on 1 device. And I did just that hats off to the developer for this.

There's an uninstall button in the app. Or, you could just flash the original boot.img via TWRP (basically what the uninstall button does).

I'm a noob...What is this? Where do I need to go to learn about why I would want this...Please explain lol

Thanks for bringing us this tool. One thing I can't figure out...how do we Odin a different bootloader? I have DOK2 loaded now, and want to put Dr. Ketan's on the phone. The sub instructions say to Odin the BL and CP, as the ROM is generally generic. There us also a datafix and an essential fix that needs to be applied. Doing all of that is easy, but how do I keep two separate bootloaders (LP and MM) totally separate? If I flash a LP over a MM, my camera breaks, and if I flash a MM over LP, WiFi breaks. And I'm not talking about dirty flashes, a full system, data, and cache wipe 3x. Only Odin back to the base ROM keeps my phone happy.

There's no way to have two different bootloaders. EFIDroid comes between the bootloader and the boot.img, so it has no control over the bootloader.
EDIT: EFIDroid may be able to emulate the behavior of another bootloader... you would have to ask @m11kkaa for details...

I will have to look into it... The EFIDroid app error messages are not exactly the most helpful kind. (Good thing the app is being phased out soon). That particular error message could mean many things, but most likely it's a connection issue. We will continue this in Slack.

Will this work on tw 7.0 if i was porting a rom. Also why wont aosp kernel work on tw.. i always thought tw was aosp with skin..

Go to back to the link posted above where you got the unofficial apk and go to post #83. The OP posted an apk there that works fine on our phone.

Tried what you suggested but it didn't work either. So, I chose the 'nuclear option': I wiped the phone completely then reinstalled the stock Marshmallow ROM. using Odin. After that i installed TWRP v3.0.2 (trltetmo) and Supersu v2.79 as well as Busybox v1.26. Only then was I able to install EFIDroid successfully. Now, I'm able to boot the stock rom as well as Resurrection Remix.
It seems that if your going to install EFIDroid you must have the phone rooted using SuperSU. Using Magisk to root your phone instead of SuperSu won't work (at least it didn't work in my case).

This should work anywhere, regardless of ROM... But btw, it's a stretch to say TW is just a skin on top of AOSP. In fact, TW is probably the farthest you can get from AOSP... There's a lot of significant differences that make AOSP kernels incompatible with TW ROMs...
