[Nexus 7 Android Development] JT1510365:
Thanks so much for your Latest build aicprocks but for some reason your latest build is unusable for me. Every time i install it its usable for some while but then i install some apps and my tablet keeps rebooting over and over again and then wifi never works and i think maybe the build is broken. I never had this issue in one of your builds i forget which one btw but i dont know what to do. One of the apps i installed was ebay and i need that to make purchases hopefully you can help me i appreciate your hard work i just dont know whats going on:(
[Nexus 7 Android Development] AICProcks!:
[MENTION=5653319]JT1510365[/MENTION] Hmm, that's really unusual. Are you using the DT2W version? Did you try installing the old April version first, installing your apps, and then upgrading to the latest June version?

I know that AndDiSa made a few kernel changes last month. I heard that the May Security Updates were causing major issues for some devices. Maybe one of those may be causing your described issue. Otherwise, there were no changes to crDroid 7.1.2 in general because now the crDroid team is focused on Oreo and above.

It could be one of your apps. I once installed a game that made the tablet overheat and get severely stuck. I couldn't even uninstall the app without the tablet getting stuck again.

eBay works perfectly fine on my end. And I experienced a few random forced reboots last month and before as well, but those were memory issues due to the Samsung Internet browser having too many demanding tabs open at the same time.

Maybe you can include some more apps that you install, so I can test them on my tablet.
[Nexus 7 Android Development] AimiFox:
Does anyone know the standard size of the /system partition? Mine is 639MB, on install I have 117MB left, not even enough for GAPPS pico, let alone other stuff that is going to be installed over time.

I have also been looking for a method to safely resize it and have run into a brick wall.
[Nexus 7 Android Development] vartanarsen:
Hi guys, I just bought a Nexus 7 and i updated to latest official 6. Then i find out OTG Support doesnt have support for exFat, only FAT32. If i try to do Nougat, will it gain exFat support for OTG?

Also can anyone take my nexus 7 and do it for me for like $20-$30 as i am completely illiterate on all of this...
[Nexus 7 Android Development] AICProcks!:
[MENTION=4288805]AimiFox[/MENTION] Do not attempt to manually resize your partitions on this device. There is a very high chance you will brick it forever.

To install Gapps Pico, just download and place the Open Gapps System Size Fix from the first post in the same directory or folder as Gapps Pico and then flash Gapps Pico https://androidfilehost.com/?fid=745849072291693897

Afterward, you can also root with SuperSU and uninstall some unnecessary system apps.
[Nexus 7 Android Development] AICProcks!:
[MENTION=6072233]vartanarsen[/MENTION] You could try to find an app that is compatible with exFat such as the StickMount app or Paragon's Total Commander plugin https://www.androidpolice.com/2017/...plugin-brings-exfat-ntfs-hfs-support-android/

As for installing crDroid, its not too complicated. Just follow along with this video series https://m.youtube.com/watch?v=CV2gNE6XTxc

Here is the fastboot and ADB program you need https://www.xda-developers.com/google-releases-separate-adb-and-fastboot-binary-downloads/
[Nexus 7 Android Development] sany:
I need guidance please

It has been many years since I played with custom rom installations and in those years things have advance and I am unable to follow several things. All I used to do earlier was flash the custom ROM and GAPP but now I see additional steps, can someone please guide me with the instructions in the first thread:

Can you helps with the below instruction on formatting, as I am confused If I copy the ROM and GAPP after formatting will it be difficult to get my PC identify my tablet?

2. How do I perform this formatting

3. Are these formatting options available only in any specific versions of TWRP?

- If you want (recommended), you can format ONLY Data and Cache partitions to F2FS. System partition must be EXT4! (Once again, you will lose your data!) (If you use EXT4, you can run fstrim to maintain ROM.)

thanks

Hello,

I've got the issue that the circle button for home and the square button for app history in the smart bar don't do anything. The back button works though. Also if I'm in a game app the bar dissapears and can't swipe to appear again. Did I something wrong? (I followed the tutorial on the first page)
[Nexus 7 Android Development] Pumpk1in:
Hi !

I have a huuuuuuuge battery drain :/

Caused by "Kernel (Android OS)" so I assume it's something in the ROM ?

The tablet can't stay more than 24h on with screen off, sync off and wifi off (auto when screen off). Strange !

Any idea ?
[Nexus 7 Android Development] NexuStar:
Hello, just wanted to say thank you for this rom my 2012 nexus 7 just got a new life. Super fast like the first day.
[Nexus 7 Android Development] AICProcks!:
[MENTION=362755]sany[/MENTION] You should be able to flash the newest TWRP for Grouper without much trouble. You will need to use the fastboot adb tools. EXT4 should be fine, but I use F2FS. When you choose each partition in TWRP, there are options to format or to change the file system to F2FS, etc.

Otherwise, you are just updating TWRP, and everything else is the same as you were used to. Of course you need to include the small Gapps system size fix in your rom and Gapps folder.
[Nexus 7 Android Development] AICProcks!:
[MENTION=9358151]Akariu Tamiokiy[/MENTION] When you customize the Smart Bar, long press on the circle or square button to assign an action to the short, long, or double press.
[Nexus 7 Android Development] AICProcks!:
[MENTION=3441915]Pumpk1in[/MENTION] Make sure you downloaded the normal version of the rom, not the DT2W version.

In my case, since I use Gapps :confused: :laugh:, both versions provide excellent battery, but the normal version is the one that should provide you better battery life.
[Nexus 7 Android Development] JT1510365:
Hey buddy just wanted to let you know that i created my own crdroid rom which is based on yours:)

I just wanted to let you know that i will never profit from your work as id didn't compile this rom but i instead based it on your build to let people get something different:)

I hope you can understand that i am not trying to steal from you:)

In the meantime can you check out my Crdroid rom and tell me what you think?

Cheers:)

I also gave you full ownership and credit:)

[MENTION=5653319]JT1510365[/MENTION] Hey there! As I mentioned before to you, the real authors of crDroid are the ones to thank, such as [MENTION=4478519]Cristiano Matos[/MENTION]. :D Thanks anyways! However, I also don't profit from this as its open source. Also, I didn't post a new update since June because I was waiting for new security updates, which seem to be the July Security Updates. Are these the latest security updates in your rom?
[Nexus 7 Android Development] JT1510365:
Security updates aren't changed and they are the same as your ROM which are the june security patches also I thought crdroid 7.1.2 was based on lineage OS 14.1 so you should be able to get the august security patches:)
[Nexus 7 Android Development] AICProcks!:
[MENTION=5653319]JT1510365[/MENTION] I thought you compiled your rom since your crDroid version is newer in your post.

Even though the security updates are based on Lineage OS, the crDroid developers need to integrate these security updates. According to the crDroid Github page, it seems as if the current update is from July even though it was integrated all the way in August:

(The crDroid team seems to be focused on Android Pie 9.0; if only Grouper would get Android Pie :fingers-crossed: )

[Nexus 7 Android Development] JT1510365:
None of the ROMs i make are compiled from source like i said my ROM is based off your ROM. Let me walk you through the steps on how i made my crdroid ROM. I didn't compile my crdroid ROM or even my slimkat ROM as i dont know how to compile ROMS in the first place.

1. Download and flash your crdroid ROM v3.8.8 as well as my custom beans gapps to my nexus 7 grouper

2. Boot up tablet and finish setup wizard and then flash supersu to get root access

3. Download root explorer apk from play store so i can edit build prop to change crdroid version and other things and add or remove files or apps in the ROM and system

4. Download terminal emulator apk from play store so i can use terminal emulator to make the rom into a system.img file right from the tablet itself

5. Copy System.img which is the modified rom i made onto my computer using mtp and copy it to my rom folder

6. Add my custom updater script as well as your boot img i extracted from your rom onto my computer and using my computer i zip all the files and then thats my rom
[Nexus 7 Android Development] AICProcks!:
[MENTION=5653319]JT1510365[/MENTION] :D You didn't need to explain, lol. I know what you meant; I was just referring to the version number in your post.
[Nexus 7 Android Development] AndDiSa:
... wouldn't it be easier to provide an updater script only which can be flashed by recovery and which is doing your modifications on the original ROM? Probably this script could be even compatible to different ROMs / different versions of the ROMs so you wouldn't need to do it again and again ...
[Nexus 7 Android Development] razzor1984:
Hello, any chance that the October security patches will be integrated in your rom?
[Nexus 7 Android Development] AICProcks!:
[MENTION=4894344]razzor1984[/MENTION] Unfortunately, it looks like that won't happen :(. The last update the crDroid team made to Nougat 7.1.2 was in August with old July security patches. They seem to have moved onto Android Oreo and Pie.

Yep, I just contacted Pranav, a crDroid developer, by email, and he says the crDroid team won't support Android Nougat 7.1.2 anymore because of limited resources.

Another way to DL these Fix files?

Is there another way to access these fix files without having to use Zip Extractor? Zip Extractor wants access to my Google Drive and I'm comfortable allowing that. Is there a direct download link?
[Nexus 7 Android Development] AICProcks!:
[MENTION=5820202]bodotdot[/MENTION] If you're referring to [MENTION=5653319]JT1510365[/MENTION]'s initial setup wizard fix, then I can provide an Android File Host link. But why would Google Drive need access to your account? Try opening the link in a web browser instead of the XDA app. You don't need to login to download a file from Google Drive.

Here's the Android File Host link to [MENTION=5653319]JT1510365[/MENTION]'s fix https://www.androidfilehost.com/?fid=11410963190603880732

P.S. I'm not sure if this answered your question. You don't need to extract the zip files. You need to flash them in TWRP. But if you actually want to extract the zip files, use ES File Explorer instead of Zip Extractor.
[Nexus 7 Android Development] bodotdot:
My mistake--all set

[Nexus 7 Android Development] tuserr:
Hi AICProcks,

Thanks for your efforts for porting this awesome Rom,

I just want to ask you about the performance of this ROM in compare to [MENTION=2188693]AndDiSa[/MENTION] - AOSP 7.1 and [MENTION=3729448]aaopt[/MENTION] LOS ROMs as you know that Nexus 7 is very slow and you ROM has a lot of customization, so will the performance as good as [MENTION=2188693]AndDiSa[/MENTION] - AOSP 7.1 and [MENTION=3729448]aaopt[/MENTION] LOS ROMs or less than them? :)
[Nexus 7 Android Development] AICProcks!:
[MENTION=9512894]tuserr[/MENTION] That's a good question, but in this case, I might also add stability to this question. In my opinion, the "most" stable rom with performance is either AOSP or LOS. Since I like a little more customization, and with stability in mind, I would pick LOS.

I basically made crDroid since it had the most customization available with the SmartBar and I like SlimRecents. And also, for some reason, crDroid usually provides the best battery life for me on different phones. But as for stability, crDroid is less stable than AOSP or LOS. Some users claim that even though crDroid on Grouper is less stable, it provides faster animations. In my experience, I found crDroid stabilizes after a few days, but overall, it was a somewhat frustrating experience since I had to keep force closing more feature packed apps.

For what its worth, I would possibly try all three so you can see which one is the most stable for you. In addition, I recommend the ButterFly Web Browser even though its outdated because it is lightweight and gets stuck less often.

If you want good battery life, do NOT use crDroid with DT2W. This DT2W feature keeps the screen awake.

P.S. crDroid 7.1.2 is no longer updated since the developers do not have enough resources available and have moved on to Oreo and Pie.

Mod edit: OP quote removed

Hi there. First off: Amazing ROM!! Now for the troublesome part. I have tried to flash openGapps 7.1 pico and it always come back as Insufficient space or something of the sort Error 70. What am I doing wrong? Thanks in advance.
[Nexus 7 Android Development] JT1510365:
you dont need to flash gapps as its already included in the rom:)
[Nexus 7 Android Development] ecobio30:
The guide even says to flash openGapps 7.1 pico, since the ROM does not come with any Google-related app. Hence the question as to how to flash it and avoid the Error 70.
[Nexus 7 Android Development] AICProcks!:
[MENTION=4748608]ecobio30[/MENTION] Just place the Open Gapps System Size Fix in the same directory or folder as the Open Gapps Pico zip on your tablet. The file is named "gapps-config-grouper.txt" and is available here https://www.androidfilehost.com/?fid=745849072291693897
[Nexus 7 Android Development] ecobio30:
I did. Even went further and put it inside the zip (to see if it worked like that) but I am still getting the same error
[Nexus 7 Android Development] JT1510365:
sorry i thought this was my crdroid thread my mistake why dont you just use my crdroid rom it has gapps already included:)
[Nexus 7 Android Development] ecobio30:
Is it for the grouper? Where can I find it?
[Nexus 7 Android Development] AICProcks!:
[MENTION=4748608]ecobio30[/MENTION] You do not need to unpack the Open Gapps zip. Just place it in a folder. In that same folder, just place the fix text file. It should flash without any problems. Make sure you're using Open Gapps for Nougat 7.1 and ARM. If it boots up, you will likely face an error too, but [MENTION=5653319]JT1510365[/MENTION] provided the fix as well. I provided the original crDroid rom without changing the source files.

Otherwise, [MENTION=5653319]JT1510365[/MENTION] modified rom is here: https://xdaforums.com/nexus-7/development/rom-crdroid-v3-8-9-unofficial-grouper-9-t3844534

Hello. Thanks for the firmware.

I have got Build 2018-06-18 (7.1.2_r8_DT2W).

Trying to install microG as the alternative to GAPPS. I can't make it work because can't enable spoofing signature. Searching in settings gives nothing. How can I enable

spoofing signature

?

edit: I have found it in settings - crDroid settings - miscellaneous
[Nexus 7 Android Development] AICProcks!:
[MENTION=4863730]gintama_me[/MENTION] I am not sure if it will work, but you can try enabling spoofing signature in "Settings>crDroid Settings>Miscellaneous>Allow signature spoofing".
[Nexus 7 Android Development] jasius:
The only issue I have is that sometimes it takes a very long time for the keyboard to popup and occasionally my tablet just locks up for no reason, sometime if I'm running Joey(reddit client) and I open Brave it'll take so long that'll just time out and lock up.
[Nexus 7 Android Development] Badcatalex:
Help, I did everything correctly but the OpenGApps package keeps giving the storage error (code 70)!

I put everything in the right directory, too. (Yes I put the "fix" .txt file in it too)
[Nexus 7 Android Development] AICProcks!:
[MENTION=7398361]Badcatalex[/MENTION] It seems like OpenGapps Pico size increased. Maybe you can try to use an older OpenGapps zip from last year? Then you can try removing some system apps that you don't need. Then, you should be able to install the newer version of OpenGapps. The system size of this tablet is very small, and even just a few megabytes make a difference.
[Nexus 7 Android Development] Badcatalex:
Hmm... where would I get the older .ZIP then?

Plus, how could it not have enough space when it's a fresh install?
[Nexus 7 Android Development] AICProcks!:
[MENTION=7398361]Badcatalex[/MENTION] Yes, the System partition space is very small on the Nexus 7 2012 tablet even on a clean install with this feature packed rom.

I just checked my Nexus 7 2012 tablet, and I have OpenGapps Pico from June 18, 2018. :D Currently using a new highly recommended tablet Huawei MediaPad M5. :good:

You are right, OpenGapps doesn't post these old releases anymore. In that case, you can refer to Post #76 in this thread to remove unnecessary System Apps to make space for OpenGapps Pico (link below).

Or, you can just simply refer to [MENTION=5653319]JT1510365[/MENTION] modified rom (the link is posted above a few posts back) based on this rom which already includes OpenGapps.

Is there a way to increase the max number of users or actually delete the guest account on this ROM? I'm trying to setup this tablet for my 4 kids with family time, but once the 3rd kid was added, the "Add User" item was greyed out with the message "You can add up to 5 users". If not, I can just remove myself, but I'd rather not.
[Nexus 7 Android Development] AICProcks!:
[MENTION=5867321]FlyOnTheWall43[/MENTION] I looked around in the crDroid source files on Github, and I found a lot of files relating to multiple users. However, I couldn't find the one relating to a max of 5 users. Anyways, it would involve modifying the framework source files and rebuilding the rom again. If someone here knows how to properly modify these files, I could rebuild the rom for you. However, I am not sure why there is this limit; possibly because of the small System partition size on this tablet.

EDIT: Actually, it seems like it is a simple change in the source files. I will try to rebuild the rom and see if it works. It will take a couple of hours.
[Nexus 7 Android Development] FlyOnTheWall43:
Really? Thank you!
[Nexus 7 Android Development] AICProcks!:
It might work. Currently, in the source file it says a maximum of 4 users. I guess the 5th one is the guest.

Hi.

I am trying to flash from 4.4.3.

I have wiped cache, data and system.

When I try to flash this ROM, it tries to flash it but stops at 3-5% and does not move (15min already).
[Nexus 7 Android Development] AICProcks!:
[MENTION=4381941]cesedy[/MENTION] I had a similar problem with another rom. It turned out to be a corrupt file so I redownloaded the rom again from the internet.

Also, make sure you have the latest TWRP installed. Which TWRP version do you have? https://dl.twrp.me/grouper/
[Nexus 7 Android Development] cesedy:
Downloaded again and it helped. Thank you.
[Nexus 7 Android Development] AICProcks!:
[MENTION=5867321]FlyOnTheWall43[/MENTION] So I edited the source file regarding multiple users, and I think it should work without any issues. But I am getting a lot of build errors this time around just before the 88% point. It looks like crDroid changed a lot of source files around in their Github repository. I will try to fix them, but no guarantees. And to add to that, the build time is much longer than before. So it will take much longer than expected. Sorry to keep you waiting.

If I manage to sort out this issue, there should be an update in the next few days.
[Nexus 7 Android Development] FlyOnTheWall43:
No worries, thanks for the heads up and for working on this
[Nexus 7 Android Development] FlyOnTheWall43:
Have you had a chance to get this done? Not trying to be pushy, just haven't heard from you in a little while.
[Nexus 7 Android Development] AICProcks!:
[MENTION=5867321]FlyOnTheWall43[/MENTION] The regular build is not building anymore. crDroid does not update their source anymore. I contacted a crDroid developer, but he didn't reply to my message. I doubt he will reply because he already told me a year ago that crDroid doesn't support Nougat anymore. He said there were not enough resources available to continue supporting Nougat.

Currently, I fixed one error, then another one showed up. Then, I fixed that one, and then another one showed up. Now, there is an error that I don't know how to fix. But it looks like there will be a new error as well.

I would need help from a more experienced developer / builder to get the basic crDroid building again.

If it weren't for this, I would already have your build ready on the first day because it only took around 3 hours to build up to 88% at which point it gets stuck.

P.S. And, this error is not related to the multi user modification. The basic build that I have detailed in the second post of this thread is the problem.
