Screen casting never worked on 2012 nexus. Don't know about chromecast support, but it's for sure not capable of wifi direct/ miracast.

Regarding lollipop: no problems at all updating from stock kitkat. Even CF-Auto-Root performed it's magic without a glitch ;) However there are some apps incompatible with lollipop like mx player, sygic etc.
[Nexus 7 General] jetsaredim:
Honestly, if I didn't care about root, I'd be happy as a clam with this build. Works very well. The issue is the increased security from SELinux in the kernel of 5.0 that's causing an issue with installing root.
[Nexus 7 General] desiresiscool:
how do you root, i've tried cf root and flashing the custom kernal with superSU 2.19.zip but i still can' t get root
[Nexus 7 General] jetsaredim:
That worked like a champ - thanks! No need really to run the script as I'd already done the oem unlock, but booted that kernel and root works now. Thanks!

full clean wipe?

Looking to do a full clean wipe and install this as a new (stock) image. What are the commands for that?

I've got adb and fastboot working, and my data is backed up.

Are there any tools to format the internal storage to try and clean it up so it's not so laggy like it is now?
[Nexus 7 General] elfanto:
Well, just flash this image about 10 minutes ago, the first boot took around 5-10 minutes then i restore a backup of my google account and the tablet is now installing all the apps that i use.

So far, all looks great, even better then the port of the Nexus 7 2013. Flashed the image using Nexus 7 Toolkit and i erase all the data, so it was a clean flash.

Everything looks great! :good:

Worked OK using #mirror enabler under CM11 M10.... Was slow, but worked!!

Was kinda hoping for better than an a tray icon that seems to do nothing. Certainly, monitoring logcat whilst hitting "Cast Screen" button results in zero additional log entries.

[Nexus 7 General] RuuddieBoy:
Can anyone write a small guide about how to flash the images and root with CF-Auto-Root, to make sure us noobies don't make an irreversible mistakes?

I see there is some stuff about the fastboot commands you're supposed to execute in the 2nd post, but later in the topic people said some aren't needed. Perhaps if a step-by-step guide can be written, that would be wonderful! :D

Flashed, found it was as laggy as 4.4.4, so moved to an F2FS ROM and have decent performance back. Apologies for what may be a nobbish question, but is there any (non major dev work) way of making this ROM F2FS-compatible?

or

Click on "flash+unroot"

2. there are a bunch of files in the leaked factory img; which one(s) shoud I flash?

Nexus Root ToolKit - Updated for LRX21P - Root achieved

I put the leaked ROM on last night with Nexus Root ToolKit. It made the task of flashing the ROM a pain free experience., especially as my bootloader was already unlocked. I decided to update my copy of Nexus Root Toolkit this morning on my work PC and discovered that the program has been updated to include LRX21P!

I re-ran the root function and I seem to now have root access ( as reported by Root Checker Pro ) but Titanium backup says I do not have root. Does anyone have any ideas on why?

flashed

ok, so I flashed this (clean flash, coming from cm11 official), no root or custom work, just the leaked image.

My hope was that it would bring some life back to the tablet that had become super laggy lately.

It's better, but still not as good as it had been. I was easy on installing apps, didn't do much customization at all.

So far not thrilled. Anyone have any tips on how to get some of the speed back?

I'll let it bake a day or 2, maybe it's still settling in.

Hope it's more of an improvement.
[Nexus 7 General] AJ06:
It is the stock kernel, it underclocks like crazy (50, 100, 200 MHz = laggy)

I rooted (Chainfire), installed Trickster MOD, which lets you change the minimum MHz. I set it to 300 and all is back to normal.

I'll lose some battery life but I NO CARE.

Good luck.

I just ran the .bat file (which is included inside the .zip file) while the tablet was in fastboot (bootloader). You should be good to go, just follow the instructions that appear in the command screen.

Are you running the UPDATE command? ("Update" to 4.4.4 from Lollipop)

If you're going back to 4.4.4 you may need to wipe. Unless you're trying to update TO Lollipop.

Can any other person confirm?

Is it possible to make a flashable zip file?
[Nexus 7 General] Drake008:
So the Bootloader has not changed? The OEM Unlock will be still disabled?

So we do not need to flash radio and recovery. Am I right?

If we flash recovery, twrp would be gone, or not?

Are my installed apps (4.4.4) still on the device or must I install everything again?
[Nexus 7 General] 9Lukas5:
What means oem unlock is disabled?

And yes, if you want to Update instead of factory reset, you only have to flash system and the fixed and rootable kernel. Modem isn't existent in wifi version, therefore also no modem to be flashed (y)

So fastboot flash system system.img is enough.

The kernel is where to be found or is it in the system.img or is there a zip (kernel and supersu) that I install after I flashed the system.img.

I have a newer supersu downloaded from chainfire. So now I need the kernel to get the Nexus speed up and this security measures away?

Lrx21p image working - need to check for bugs

Just to give my experience in a few lines to help 'newbies' and others who had problems:

1. Used Wugfresh 1.93 with updated list of images for Lollipop

2. Flashed stock LRX21P without any problems. After booting flashed TWRP using Wugfresh.

3. Copied Boot-Root-5.0.zip from an earlier page and Supersu beta 2.19 using usb drive.

4. Booted to Recovery and flashed Boot-Root-5.0.zip from USB. Then rebooted to recovery and flashed Supersu.

5. Reboot and everything works ok. Should when connected to W/L install your apps, email, contacts etc.

6. Good to go.

Shows correct amount of space for 16GB Nexus 7.

Need to give it a proper workout for bugs.
[Nexus 7 General] demolition23:
May I ask what's that star?
[Nexus 7 General] 9Lukas5:
[MENTION=798069]Drake008[/MENTION] the kernel is provided as a flashable zip on the third page if I'm not mistaken.

So you need the system.img, the kernel as flashable zip, and Supersu Beta 2.19 or later.

Then

- fastboot flash system system.img

- goto recovery

- flash kernel and SuperSU

- wipe cache

- reboot to lollipop

[Nexus 7 General] Nasalhair:
The star relates to priority notifications. You can disable notifications during certain times (via sound settings, Interruptions) - go to the "When notifications arrive" setting and set it to "always interrupt", and the star disappears. If you change it to "allow only priority interruptions" the star appears, indicating you are in DND mode.

I wondered this too when it appeared on my Nexus 5 last night. Found the answer myself on Google :)

Well, I've been on this thing, rooted (using the flashable kernel) for about 24hrs now, & the battery life is crazy bad. e.g. I had it plugged in overnight, as usual, & when I woke up to unplug it for work, it was still sitting at ~70%. Does anyone know if this image has the battery bug?
[Nexus 7 General] Drake008:
Thanks.
[Nexus 7 General] Nasalhair:
Personally the battery life of my N7 2012 is better with this image than it was on KitKat, but I must stress that I've not rooted nor have I used any alternative kernels - I just ran flash-all.bat from the image file and left it at that. I did try the ROM called "straight from source" last week though & the battery life was atrocious - it had the bug where the battery stats had "miscellaneous" eating up most of the resources, but this official image doesn't have that issue.

The one thing I have found is that my N7 is still dog-slow to the point of being almost unusable, something it has suffered from for the last six months or so. Was considering upgrading to a N9 but having seen lots of iffy reviews of it I'm considering just sticking with my N5.
[Nexus 7 General] t-readyroc:
To clarify - I'm only using the kernel that allows root. No other modifications (that I'm aware of, anyhow). Screenshot.
[Nexus 7 General] Funnnny:
I just use faux kernel zImage, with fstab and the original boot.img from factory.

The first time I success, I can't get root working, now I'm trying something different.
[Nexus 7 General] Drake008:
- flash kernel and SuperSU - DONE for Kernel and FAILED for SuperSU

I downloaded the file from https://plus.google.com/+Chainfire/posts/ZzXaU1W7Uzm and after that from http://autoroot.chainfire.eu/

Both give me a failed.

OK now were coming to an end, i hope.

So after the KErnel flash from TWRP I have to go back to fastboot and boot the img in the zip it seems. Booting up for the first time after wiping dalvik and cache.

LEt'S see if everything works.

Works fine. A little bit "laggy" but it works.

Flashed the official image after flashing the leaked version yesterday, rooted using cf auto-root (I already miss the days of fastboot flashing a recovery, then the supersu zip) and everything seemed fine. Root just isn't working right for certain apps like ES file explorer and Quickboot. Both are showing the "position independent executables" crap in su logs. I flashed a pie-enabled zip file that's kicking about, that other users reported success with on a variety of devices but it apparently hasn't worked. Is this experience the same for everyone else?

I also have a problem with ES file explorer
[Nexus 7 General] ichigo_kurosaki:
Same here. Did the image flashing and rooting using NRT.:D for flashing factory image, just click on "flash stock+unroot" and follow everything. But obviously you first need to set up your device for adb and fastboot connectivity, which you can also test using the toolkit.

[Nexus 7 General] bhargav143:
Performance is acceptable.. Antutu scores nearing about 20k mark.... Some apps run smoother some take much more time to start... All credits to NAND dependency of Lollipop...

Anyways... On the other hand....

I felt Google did not solve anything they have just hidden the miscellaneous battery issue....just to release the lollipop as scheduled..

I get much lesser SOT (3-4 hours) compared to 5+ hours on KK... and while using with WiFi battery decays exponentially... While Wi-Fi not being used... it acts normal....

Another thing, WiFi was on for 12 hours almost and accounts to only 1% battery? I don't agree.... Google(battery stats) is faking this time I feel....

I hope the above is not true......

Is there anyone who agrees and experience the same?

When swiping over my homescreen I can count almost frame by frame. When clicking, I touch the screen, and 3 or 4 seconds later the animation comes, then more 2 or 3 seconds to execute whatever I've clicked.

My Wifi disconnects everytime, and I have to go to settings, rescan and reconnect, 'cause when the connection is gone, my N7 can't see any other network (until I refresh it).

I was so excited about lollipop...but how it did come to this?

It's just me or anyone else is facing those same problems?
