Mine did the same thing. I downloaded the Quick Boot app from the playstore to get there. https://play.google.com/store/apps/details?id=com.siriusapplications.quickboot&hl=en
[Nexus 7 Android Development] melp57:
I reformatted data and cache, incredible smooth and fast everything. Just what this do to make such a profound different?

Thanks for the help. I have used quick boot before and was missing it on the rom. Didn't know that it was in the Playstore. Everything is fine now :)

Thanks for the new 9.6 weekly from August 18. With this version, everything is running great again on my Nexus 7 in combination with M v77 kernel and Xposed framework (got bootloops with official 9.6.

[Nexus 7 Android Development] leechheart:
guys help me please!!

i installed franco kernel with dirty unicorn rom.

the problem is when i am starting my tablet nexus 7 2012 wi fi it appears the system shuts down and i can t do anything only to restart the tablet

the only way to enter in recovery mode is by laptop with nexus root toolkit, when i am trying to enter in recovery mode it is appearing an android with an red angle inside

please help what to do?!
[Nexus 7 Android Development] howasparty:
Press Volume + Power for some seconds and then release Volume (not Power). It should switch to the recovery then
[Nexus 7 Android Development] leechheart:
I tried howasparky but it doesn t work
[Nexus 7 Android Development] bbc0:
I have 9.6 and everything works well except for the home button which seems to do nothing. I have tried to have it do different things using DU tweaks but still nothing. Anyone else having this issue?
[Nexus 7 Android Development] howasparty:
Did you try several times?

You could try, getting into bootloader and then use Nexus Root Toolkit or just fastboot to start your recovery.

Switch Nexus off, then start with Power + Volume DOWN. Connect your device to your computer and start the toolkit. You should be able to use it now.
[Nexus 7 Android Development] leechheart:
"your device will boot into twrp", but it doesn t boot, it is stuck on bootloader

Last night the battery in my N7 2012 died. After charging the N7 was stuck in a bootloop. I decided to try to reinstall DU 9.6 but stupidly wiped everything. Now I can only get into Fastboot and also TWRP but I have no zip to flash. How do I get an image back onto my N7? Any help will be appreciated.
[Nexus 7 Android Development] MauroRTR:
enable MTP in TWRP and copy the ROM from your PC to the internal storage.
[Nexus 7 Android Development] bbc0:
In TWRP MTP is enabled already but when I connect to my pc the N7 does not show up. I tried disabling it but still nothing.

I think that this is because I can't get in to enable USB debugging etc?

When I look at Device manager on the pc I can see the N7 show up when I connect it and disappear when I remove the usb connection so it looks like something should be showing.
[Nexus 7 Android Development] bbc0:
I managed to reflash DU 9.6 from a thumb drive to my N7 , but after rebooting I am back where I started with the DU/Lolipop logo spinning for over an hour.

Any suggestions?
[Nexus 7 Android Development] vusun123:
Thank you for the releasing this wonderful ROM. It revives my Nexus 7 from the terror of stock Lollipop :D
[Nexus 7 Android Development] bbc0:
OK, so I loaded another older Jellybean ROM that I had from the thumb drive using OTG and it booted up just fine. I can move into TWRP and back using the buttons with no problem at all. I'd sure like to know why I can't do all this using DU 9.6?
[Nexus 7 Android Development] mikle_01:

[Nexus 7 Android Development] QuickNET Tech:
A dirty flash should be fine. You should experience no issues, but if you do, just do a clean install.
[Nexus 7 Android Development] zoko:
ok, tks.
[Nexus 7 Android Development] JeanPi23:
I'm not able to access my internal storage. I'm guessing it has to do with my previous rom being f2fs. This rom isn't f2fs, right?

You should be able to run f2fs for data and cache. Not system tho

Sent from my Dirty Nexus 6
[Nexus 7 Android Development] JeanPi23:
Thanks for the quick reply. Any suggestions to what it could be? Should i go back to an F2fs rom to be able to access internal storage or should i format back to ext4 and start from scratch?
[Nexus 7 Android Development] Treboeth:
Hello all

I wanted to to a clean install of 9.7 and format my device as well.

I have a Kingston 32gb microdrive which I have all the necessary files on.

When I plugged in the microdrive it crashes my nexus and it can only be restarted by plugging in ac cable.

Googled and there is a known problem but I can't find a fix for it.

Any suggestions?

Hello the 9.8 is lollipop or 6.0.

What the news for 9.8?
[Nexus 7 Android Development] biondi53:
LP
[Nexus 7 Android Development] Spiceworm:
I have horrible wakelock problems in 9.8. Leaving it unused, full charged, 10 hours later the battery is empty. Empty like it won't show charging screen when a good 2 amp charger is connected.

9.7 had lockscreen unlock lag. Why even bother to go to Marshmallow if you know you can't get a working rom because google already released the next buggy OS? Why not make lollipop fully functional and perfectly working? That is a lot more usable than the next-gen OS that has bugs...

I have 4 android devices to maintain and those are generating wakelocks faster than that I can fix them. It is driving me crazy!!
[Nexus 7 Android Development] DutchMan_1990:
Install Better battery status and find the wakelock culprit. Or maybe your battery has doomed.
[Nexus 7 Android Development] ummduh:
I was having this issue when I was flashing DU + the GApps linked in his post. GApps wasn't really working for me for some reason so I reflashed just the DU itself and didn't install GApps and the home button now works correctly. Also an oddity was that there were a lot of SU requests from the system, and the settings wouldn't load for a couple minutes after opening them.

I ended up downloading the CM GApps micro version, everything is working great now.
[Nexus 7 Android Development] meatfest1974:
...yeah, I was having the same problem with all the Grouper Banks GApps alongside with v9.8. Instead I ended up using the CM 12 GApps from another post (gapps-lp-20141109-signed.zip).

The setup is going smoothly thus far.

By the way, how's the battery life on this?

Oh, are you sure this is for Grouper? If it's Wi-Fi only, why is there "no service" in the upper left? My assumption is that a possible battery drain is a result of a (non-existent) radio.
[Nexus 7 Android Development] lostsurfer:
Every time I boot up this rom, I get android keyboard has stopped... :(
[Nexus 7 Android Development] Thebear j koss:
what bum from DU is maintaining this nowadays? is [MENTION=4433359]spaceman860[/MENTION] still in charge here? i just got a nexus 7 cheapo and will most likely be flashing this unless i'm advised to use something else. ....
[Nexus 7 Android Development] spaceman860:
Lol... Version 9.8 is the final version for grouper. I will not be supporting it anymore for marshmallow.

Sent from my Dirty Nexus 6
[Nexus 7 Android Development] Thebear j koss:
no worries. i mean this device is going on 3 years now, i don't really expect much support for very long, but i figured i gotta at least flash something i know is good and i don't need to worry while i get situated. lollipop is fine for me, i'm no update slut. lol thanks buddy.
[Nexus 7 Android Development] ummduh:
As far as battery life, can't say too much. It's my son's tablet, and he mostly has transitioned to using his 3rd gen moto G instead of this cuz it's pretty laggy (that poor NAND sure makes itself apparent). All I can say for sure is it's dead dead dead after less than 24 hours of 100% standby.
[Nexus 7 Android Development] meatfest1974:
...ugh, my condolences. I have been digging around xda and found out about some fstrip app in the Play Store that helps a lot with the lagginess. I've also applied some other thing called Kernel Adiutor just to tinker with the CPU governor.

Is Marshmallow a little less merciless? I'll give that as a shot with an Android 6.0 custom ROM, if it was worth it.

I'd hate for this device to end up in the legacy morgue so prematurely, in my opinion.

So much potential, so much lag.
[Nexus 7 Android Development] gtr33m:
It's a problem with the gapps package that is recommended in the flashing instructions. The gapps package is for 6.x.x, while this ROM is 5.1.1

Using the 5.x.x version from the DU site will not work either, I suspect because it is too large.

There are several in this topic that will work. I've had the most success with gapps-L-3-14-15.zip

This link currently works, but if it fails in the future, do a search for the above file

Battery Life

I must say, I'm using v9.8 and have NO issues regarding the battery life, it lasts more than a Duracell Bunny.

I do however have issues on wakeup, dayme they are frustrating, have to reboot almost everytime! :(

A few lags here and there, after rebooting a few times it seems to work, when it's on, when I press the power button for standby, and turn it on again, all lag-hell breaks loose!

regards,

Pedro.
[Nexus 7 Android Development] DJB628:
OK, decided to check this ROM out, have not rooted as of yet, as the Nexus 7 was the wife's and she could not deal with the lag and slowness anymore, So I got her a new tablet ;). I was going to sell this one, but for $50 it's not worth selling, so I'll keep it to play around with. Heard alot of good things about DU Rom, Will this Rom speed up this Tablet ?? and as I was reading this thread, I guess the Gapps in the OP post, is not the best to go with as it is large, so to speed up the tablet, do you guys recommend a smaller size Gapps file, and if yes which one. Thanks all in advance.

Or do you guys recommend a different Rom, I want something fast, even if it means going to 4.4
[Nexus 7 Android Development] d0nat0:
Maybe try the Slim apps by dankoman? https://www.androidfilehost.com/?w=files&flid=35754

He has an updated package for 5.1 still. I'm trying it later.

I tested a 6.0 ROM but losing rotation is cumbersome for my needs. Goodluck!
[Nexus 7 Android Development] DJB628:
Let me know when you try it and your verdict. cheers and thanks

I'm also assuming these are simply the Gapps, correct, not a Rom, and there are 2, the Slim addon and the Zero, what is the different.

[Nexus 7 Android Development] Thebear j koss:
If the dev wanted it shared he would have kept the link active. Never share work if not given the ok from the dev.

Best bet is to ask for it on the DU g+ community
[Nexus 7 Android Development] Oajj:
That's also true. Will ask from them.
[Nexus 7 Android Development] kazimserhan:
This is from their web site. I don't understand why people against sharing a GPL licensed freeware. It is GPL ( General Public License) which means it belongs to people. Of course you have to give credits to the devs but every rom and kernel for nexus 7 is down. People like me want to setup a car stereo using this tablet as a cheap unit and its hard to find the best kernel and rom combination in this dead links wasteland.

Here is my nexus 7 collection.

[Nexus 7 Android Development] Thebear j koss:
Read carefully, it is so someone can pick it up, not so it can be shared. It is true DU is built using open sourced material but there is proprietary code added in that make DU unique. It isn't hard to ask permission, you can contact any team member on g+ or find them on xda and send them a PM. DU is still quite active, just not for this device. As I stated earlier, if they wanted it available the links would not be dead.

I am soo tempted to flash this ROM, i am on SlimKat,,,,so coming from diffrent ROMs, and I know full-wipe, etc..in order..

so let me go over the steps;

download and install this: DU_Grouper_v7.7.zip

and last step download and install DU_TBO_Gapps.zip

Two questions:

Now when I flash DU_Grouper_v7.7.zip, should return to recovery and flash DU_TBO_Gapps.zip, and then reboot my tablet and conitunue normal generic setup?

what kind of recovery and version ( ClockworkMod Recovery? TWRP? PhilTouch?) you would recommending?
[Nexus 7 Android Development] spaceman860:
I use twrp recovery v2.7.1.1. Boot into recovery wipe system, data, cache, and dalvik cache then flash ROM & Gapps reboot and enjoy.
