What rom are you using currently?

If coming from another rom you will lose data yes, but not contents of your sdcard. I would make sure to copy images, downloads, etc to your computer just in case though. There is no fix to flash at the moment.

First make a backup with twrp of your existing system, then in twrp:

-factory reset

-wipe cache

-wipe dalvik cache

-install ROM

-install Purity gapps

-install supersu zip (may have to reboot and install supersu again)

This will give you a clean install of Purity Rom. You will need to setup all your settings and re download all your apps. You can backup app data with titanium backup before you flash the rom, but sometimes it causes errors when you restore on your new rom. I mainly use it for game data.

You will have the stock kernel that comes with Purity Rom. You will have to reboot and install m kernel if you want (flash kernel separately, not during initial rom flash)

Always have a rom backup available. I have a copy of the twrp folder on my sdcard on my computer just in case.

Thanks!

I tryed that but, my tablet is charging like 10% each hour.... :eek: Battery life seems Ok once is charged.

I flashed with full wipe (sdcard too)

I dont think it have something to do with but I flashed the lastest TWRP 2.6.2.0
[Nexus 7 Original Development] waz675:
I'm also experiencing the slow charge thing. Same cable and chargers will charge my spare nexus7 that the kids use like 300 to 700% quicker. So I know the cables or chargers aren't 'bad', everything else is fantastic though.
[Nexus 7 Original Development] slebit:
I have no problem with slow charging. I have tried a couple kernels, and i don't have this issue with any of them.
[Nexus 7 Original Development] tcat007:
Curious why people keep mentioning SD card in this nexus 7 thread.

I'm on stock ROM rooted with Wug's toolkit, jwr66v, m-kernel, vr theme buttons. Normally use my backup pro, TWRP back up the same? I need to do this connected to PC? I assume so since factory reset will wipe device of any zip I put on it, right?
[Nexus 7 Original Development] :
You don't have to be connected to a pc to do any of this. I just figured you may want to copy important files to your computer for safe keeping just in case.

When you rooted your device a custom recovery was installed: either twrp or clockwork mod recovery.

Twrp (Team Win Recovery) is a recovery you boot into to flash roms, kernels and to backup or restore your entire system. It is not the same as using mybackup pro or titanium backup. It backs up your entire system as is, in case you want to restore it later. Always factory reset before a restore.

Titanium or My backup pro are for restoring app data on a newly installed rom. Trwp backup is to restore an old system if your newly installed one gets messes up.

In Twrp factory reset will erase the entire system (rom, kernel, etc) but will leave the internal memory (internal sdcard) intact. You will not lose contents of internal storage or zip file that you have placed there.

Its very important to NOT wipe or format anything else unless you know what the outcome will be. In twrp in the "wipe menu" only select factory reset, cache and dalvick cache buttons before installing a rom. Make sure you have gone into backup menu first and swiped to backup.

[Nexus 7 Original Development] tcat007:
Thanks! I was afraid when I did the TWRP back up, then did a factory reset, that my back up and any zip files would be gone, since the N7 doesn't have an ext. SD card.

edit: Just flashed it and all is well (other than setting everything back up). I assume I can restore "data" from My Backup Pro of various apps (like Solid Explorer, K9 to get themed settings with the apps), or do I need to set up app settings again? I am waiting for all the apps to restore from Google at the moment. I have Purity Rom and JWR66Y. If I reboot to recovery will TWRP be there still? Will give feedback once I flashed M-kernel and set-up back to where I was.
[Nexus 7 Original Development] PulseDroid:
By far the smoothest, not fastest but smoothest ROM I've used on my N7! :) Thanks, will be running this from now, with Metrosphere icons.
[Nexus 7 Original Development] :
Yes everything should work fine. I don't use ss launcher but it should work without trouble.

Sent from my SAMSUNG-SGH-I747
[Nexus 7 Original Development] tcat007:
Must say, I like it! As smooth or smoother than stock. Like the dark Playstore! Love the notification options. I'm assuming battery will be at least as good or better (I had no complaints). Faster with M-kernel:
[Nexus 7 Original Development] Bentso:
Still using 5.7.2. It's rock stable and very fast. I wait until 4.3 version has dual panel prefs and pie before I update.
[Nexus 7 Original Development] stonebear:
I don't think there are any plans for pie, next release has expanded desktop though so just use LMT.
[Nexus 7 Original Development] veeman:
No way sequential write can actually be that high.
[Nexus 7 Original Development] tcat007:
I ran the test a few times, thought it can't be right. Must be Andrbench glitch.
[Nexus 7 Original Development] bjcrj:
I think it is due to the dynamic fsync that postpones writes until screen off.
[Nexus 7 Original Development] tcat007:
What I thought, but it's turned off in Trickster.
[Nexus 7 Original Development] bjcrj:
Is fsync off too?
[Nexus 7 Original Development] DariosF:
New build (08/9) is out! Sorry for the delay!
[Nexus 7 Original Development] slebit:
Thanks! Downloading as we speak.
[Nexus 7 Original Development] stonebear:
I think more of a fanfare was required, this is a big release. You can feel the speed. ;)
[Nexus 7 Original Development] Pinktank:
Can you choose functions for long press of nav buttons?
[Nexus 7 Original Development] stonebear:
Yep. Kill app, (happy now) etc.
[Nexus 7 Original Development] Finner42:
I can't find where to set each of these..? Hold back to kill was part of earlier versions (not sure for how long), found under developer settings - is there now some way of setting the app switcher/home button long press too?
[Nexus 7 Original Development] slebit:
Settings->System->Quick launch shortcuts.
[Nexus 7 Original Development] radekg7:
Is this rom to set transparent statusbar and navibar?
[Nexus 7 Original Development] Pinktank:
To clarify, the slim gapps are only inverted when dark UI is selected correct? Not all the time
[Nexus 7 Original Development] slebit:
Yes.
[Nexus 7 Original Development] Pinktank:
I am asking to many questions, but does it have the function where you can flip over to notifications bar to show the quick setting tiles? It's done by swiping sideways on the notifications drop down
[Nexus 7 Original Development] Pinktank:
You fooled me! There is no way to assing functions to long press of nav buttons anywhere.
[Nexus 7 Original Development] stonebear:
Sorry, it's not a long press thing, I was thinking of the "quick launch shortcuts".

edit

You know that thing at the bottom of the screen tha normally brings up Google Now? You can set other functions for it, that is what I meant.
[Nexus 7 Original Development] pointman_12:
installed on first gen n7...stuck on purity boot screen...forever...it seemed to boot and I got the updating/upgrading android then it rebooted and it seems to be stuck on boot screen...coming from bamf rom...I did wipe cache and dav before install...
[Nexus 7 Original Development] stonebear:
Do a factory reset and format system. Then install.
[Nexus 7 Original Development] Finner42:
Yup, I too am after the long press shortcuts, not quick launch. Seems there's only hold back to kill available at this stage. I like to add hold app switcher to switch to previous app, etc.

Anyway, ROM working very well - running with M-Kernel now, fast, smooth, and great battery life! :D
[Nexus 7 Original Development] stonebear:
I noticed the battery life too! I am using Faux overclocked to 1.7Ghz and it is still good, lol.

PS

What is M7?
[Nexus 7 Original Development] Finner42:
Opps, sorry, meant M-Kernel (http://xdaforums.com/showthread.php?t=2168787), getting myself confused this morning, will fix :D

I'm running at 1.2Ghz, simply for extended battery, but haven't had any problems with speed in either general usage or games.
[Nexus 7 Original Development] pointman_12:
thanks stonebear...booted right up after that...
[Nexus 7 Original Development] stonebear:
Cool. :)
[Nexus 7 Original Development] pan.droid:
Thanx, you got an md5 for this?
[Nexus 7 Original Development] RealCaracas:
Hi!! I am on previous version, and everything looks a feels great... Is the latest update a must have?

Also can I dirty flash? Or is better to wipe system and data?

Thanks again for this great ROM!
[Nexus 7 Original Development] slebit:
It's not a must. But it's often best to have the latest release. And you don't have to wipe, just flash it over the one that you have right now.
[Nexus 7 Original Development] tcat007:
Latest is 11/9 right? Changelog says 8/9. Can you update the changelog? I am on m-kernel, do I need to flash it again after flashing your update?
[Nexus 7 Original Development] slebit:
Latest is 8/9. But it was posted on 11/9. Yes, you have to flash m-kernel after you flash update.

Tablet UI

Lovin this ROM! Coming from SmoothROM 5.2. This is deffinitly gonna be my daily driver! Only question I have is about Tablet UI. Is this going to be an option any time soon? :fingers-crossed: Its the one thing I miss. Other than that, I couldn't ask for a more buttery ROM. Pure and simple! Thanks! :victory:
[Nexus 7 Original Development] RealCaracas:
Thank you! I'll update then...
[Nexus 7 Original Development] tcat007:
Just flashed update, with slim gapps. No issues. All data, widgets, settings, remained intact. Quick question, is Google drive supposed to be inferred? It doesn't appear to be. Any way to black theme it?
[Nexus 7 Original Development] pointman_12:
is there a way to add the purity settings to the quick tiles?... if not that would be a nice addition... so you wouldn't have to go to settings then go to settings again
[Nexus 7 Original Development] :
try flashing this for tabletui:http://d-h.st/G2m hopefully it works out.
[Nexus 7 Original Development] DucatiMon:
Thanks for the reply. I will let you know of it works. :fingers-crossed:
[Nexus 7 Original Development] DucatiMon:
Tried flashing it and its a no go. Just gets stuck in a boot loop. Thanks for the help though. :good:
[Nexus 7 Original Development] tcat007:
Can purity gapps be flashed over slim gapps? I'm have a wake lock issue with Goggle search (or NLP), or both. Thought I'd try a different gapps, since it started since I flashed slim.
[Nexus 7 Original Development] Auke11:
I am always flashing this gapps' only 17 mb: http://xdaforums.com/showthread.php?t=2012857
[Nexus 7 Original Development] slebit:
I would recommend to flash rom first. Then flash gapps again.

I also use that one. Working nice for me.
[Nexus 7 Original Development] stonebear:
Yes they are good but won't all ow the "dark ui" feature of the rom to work, you need purity gapps or slim gapps or if you want a small gapps I think slim do a minimal one?
[Nexus 7 Original Development] tcat007:
I ended up reflashing Purity, then the "official" gapps; big mistake, bunches of Google crap started happening, lost many sign-ins, lost calendar... so I reflashed Purity, then Purity gapps... all is well. Then flashed M-kernel, even better. Back to fast and smooth and NLP wakelocks stopped. My conclusion: something in slim gapps was causing an issue.
[Nexus 7 Original Development] :
Yea I have been having the best luck with Purity Gapps myself.

any updates on usb audio?

4.3 tested with oxydo, purified and stock kernel & no go...

heard that the most roms dont have the framework yet?

oxydo = no power to usb dac (def. kernel issue)

purified = boot-hang (mentioned kernel ready, framework/rom issue)

stock = well...stock...

also heard that cm10.2 got it working, but i'd stick with purity

did you try m-kernel? MR-2

Theme in the first post?

Hello guys,

I flashed this ROM and I'm super happy, is fast and smooth. The only thing I'm missing is the theme in the pictures from the first post, does anybody know what theme is this, I love the icons.

Thanks
[Nexus 7 Original Development] annoyingduck:
Haven't run purity since 4.2....this new build is great -awesome work! LOVE that you added the "use battery text" option. It's the greatest status bar feature a rom can have imo. Only ever seen it on eclipse. I love how large the font compared to the standard cm/slim small font.

Would love to see in future builds: add screen time out + sound quick tiles, add the full date/month/day selectable status bar options, and long press nav bar button options.

Super smooth with purified kernel.....

Am currently running the Purity Rom on my Nexus 4 and really happy with it. Just ordered a Nexus 7 so obviously my first choice will be this rom when have rooted it out the box.

Great work btw just wanted to applaude the guys involved with this rom, great battery I find with the purity kernel (have tried a few) and excellent all-round performance.
[Nexus 7 Original Development] slebit:
Yes, this rom is the best for grouper. Really stable with some nice features. And really smooth.

I am using Bricked-Kernel with this rom. It's the best in my opinion. But I guess purity kernel also is good. :)
[Nexus 7 Original Development] Doominq:

"package file was not signed correctly" error when trying to update Google Search. Latest build, Purity Gapps, full wipe, flashed twice to check, redownloaded gapps to check.
[Nexus 7 Original Development] dirtygoldfish:
If you flashed the Slim Gapps (the ones you can toggle inverted) you're going to have to uninstall system apps with TiBu, reboot, and then install the regular versions from Play Store. Can't update them normally from the Play Store, as that would break the inverted functionality.
[Nexus 7 Original Development] stonebear:
I think dirtyfish is right, uninstall search, reboot and install from Play.

Thanks for the update Dario. :)
[Nexus 7 Original Development] Tipkaros:
I actually had Purity gapps (I wrote that in my post) but your advice did help, it's working now, thanks.

Purity Gapps is based on Slim gapps that is how the dark ui function works.

It's recommended to update your bootloader. But I might work well with the older one too.
[Nexus 7 Original Development] stonebear:
Seems like lots of people don't bother updating the bootloader and have no problems...but personally I like to do it, I assume they bring out the new version for a reason so I like to have it. Might be another example of my OCD though. ;)

Anyone use Poweramp with DSP manager with this ROM? Trying to decide between Poweramp and its equalizer, or just DSP manager (they don't seem to work together).

Not at the moment i supposed... None of 4.3 rom-kernel combinations i tried (about everything out there) will work it on the n7.

There's a report at head-fi that CM10.2 worked on a Nexus4 :eek:

It's still early in 4.3 and there are more important things to sort out first, which is right.

Hence i'm still wondering if anyone has a copy of the last 4.2.2 Purity zip? Cant seem to find link to Darios' old uploads...hmm

Would also like to try Noozxoide. Should DSP manager be disabled (or uninstalled)? I read somewhere it should be uninstalled, but it wasn't built into the ROM in that case. Or has anyone tested both and stuck with DSP manager? I was using Nooz before I flashed Purity and was very happy with it. Just not sure how to test "side-by side".
