Nice! I'll need to clobber my 4.4.3 tree to free disk space then I'll try this
[Nexus 7 Android Development] fmedrano1977:
Can't get 1.6 to boot. Tried both links, keeps rebooting twrp recovery, I'm on the latest one.
[Nexus 7 Android Development] ffejy462:
Correct bootloader? Verify md5 of rom? Twrp is the latest version?
[Nexus 7 Android Development] fmedrano1977:
Bootloader=4.23, TWRP=2.7.1.1, Did verify MD5.

---------- Post added at 11:30 AM ---------- Previous post was at 10:50 AM ----------

How do you flash with flashify? Only has options for recovery and boot image.
[Nexus 7 Android Development] ffejy462:
You have the correct bootloader, so there's no need to flash.

Wipe cache and Dalvik if coming from previous kit kat version and flash rom.

Wipe cache, Dalvik, system, and data if coming from jelly bean, and then flash rom.

Do not wipe SD card.
[Nexus 7 Android Development] fmedrano1977:
Running Dirty Unicorn, same applies?
[Nexus 7 Android Development] ffejy462:
I'd do the full wipe (except sdcard).
[Nexus 7 Android Development] fmedrano1977:
Ok, I've been doing the full wipe, definitely something is wrong in the zip. After it kicked me back into twrp. I selected the backup option, to make sure I had a system, and kernel. The the system size was some 12 digit number or so megabytes.
[Nexus 7 Android Development] ffejy462:
Which version of 1.6? Odex or deodex? I had a couple issues going from cm11 to 4.4.2 (1.4?), but the two updates since, I've had no problems. I can verify that 1.6 odex flashed fine on my Nexus 7 (2012).
[Nexus 7 Android Development] fmedrano1977:
I tried deodexed as I need to be able to run XPOSED, which if I'm not mistaken, can't run on an odex rom. I'll flash the odex version may to verify if it's the deodexed rom that's an issue.
[Nexus 7 Android Development] ffejy462:
I'm running xposed on three devices, all odex roms. As far as I know, xposed just doesn't work with art (yet).
[Nexus 7 Android Development] bshiznit:
Xposed does not require a DEODEXed ROM :)

Regardless of which one you use - I would definitely redownload from the other mirror and verify the MD5 sum... Then retry.
[Nexus 7 Android Development] fmedrano1977:
Got odexed working, so I'm good now. I did download from both links, and verified md5, had same result. Initially I got the same issue with the odexed one, so I'm guessing it was an issue on my end (device). For some reason after the flash, system size was 1xxxxxxxxxxxxmb, some outrageous number. I then did some option in twrp, where it fixes system position, reflashed and all was good in my world once again. It's running smooth.

Sent from my Nexus 7
[Nexus 7 Android Development] bshiznit:
Yikes! Deodex should actually take up less room on the system partition (since the .odex files go away)... That is the first I've heard of that happening besides a few test builds I made trying to inject the play store updates in (which of course overflowed /system)...

Glad you got it working!
[Nexus 7 Android Development] ffejy462:
Glad you got it running. I was running out of ideas. ? There are a few other things that might have worked...
[Nexus 7 Android Development] funkpod:
HEllo! I have a rooted Stock Nexus 7, 4.4.2 on it. I've been trying to install the OTA updates, but it doesn't work when it gets to TWRP. I also tried using ADB sideload in TWRP, but it FAILS. Doesn't seem to be the file itself, md5 seems to maybe match with other downloads i've used.

Is the only way to get 4.4.4 stock onto my nexus7 grouper 2012 to flash this ROM? or is there another way?

Would I need to factory reset, or could I flash 4.4.4 on top of 4.4.2, dirty flash style?

THANKS!
[Nexus 7 Android Development] ffejy462:
There are a few ways to get back to stock. You could go back to stock recovery and take update or use wugfresh Nexus toolkit to flash anything (rom, recovery, SuperSU, etc) that you want or need.

I chose to flash this rom because it was stock and in a flashible zip. Since you already have twrp and stock 4.4.2, you should be able to dirty flash this with no problems.
[Nexus 7 Android Development] funkpod:
I think I'll just dirty flash this, this seems the easiest way to go. I goes you need to be on stock recovery to take an ota? Thanks again!
[Nexus 7 Android Development] bshiznit:
Yup! Bone stock or the Google official ota is gonna fail... That includes recovery partition.
[Nexus 7 Android Development] bshiznit:
Bummer - it is not full source :'( Good news though at least grouper is in the device tree! Means when 4.5 or 5.0 releases (I'm guessing it will be 4.5) we should be able to compile! https://android.googlesource.com/device/asus/grouper/+/l-preview
[Nexus 7 Android Development] nathantaylor:
Yeah, I realized it shortly after I posted it that there was only partial source. :(

But I think we'd all rather wait to have the full deal than just the preview anyway
[Nexus 7 Android Development] ffejy462:
I'm thinking considering how many changes are being made (especially visually) this will be 5.0.
[Nexus 7 Android Development] bshiznit:
Either way- I'm looking forward to it! :good:
[Nexus 7 Android Development] ffejy462:
Same here. We've had basically the same ui since fall of 2011. The l preview (other than the Playstation nav keys) looks pretty nice. Android is finally getting some of the polish that ios has always had. Don't get me wrong, I think Android has a decent ui and it was somewhat stylish at one point, but it has become stale. Good thing it's easy to change anything and everything to your liking.
[Nexus 7 Android Development] bshiznit:
Yup! ART is also revolutionary and will make a big impact. I'm glad developers got a taste in 4.4 and now have this preview to work against! Also I do have a build box and some sabermod toolchain experience see this post http://xdaforums.com/showpost.php?p=52567501&postcount=359 so yup really looking forward to full source!
[Nexus 7 Android Development] Domino5:
4.4.4 r2 (KTU84Q) is out. Can we expect BSZKitKat v1.7 ?

Edit: doesn't matter its only for nexus 5 in New Zeland and India. :(
[Nexus 7 Android Development] bshiznit:
Bummer - no new Nexus 7 factory image... Otherwise - yup I'd update the ROM in a heartbeat!
[Nexus 7 Android Development] twics:
And theres me getting all happy:eek:
[Nexus 7 Android Development] numus:
Been noticing some serious battery drain... Any idea what could be causing it? I am been trying to keep up with this f2fs and can't tell if it would be a big improvement over BSZKitKat.
[Nexus 7 Android Development] bshiznit:
For f2fs you may need to clear some space on the /system partition - see this one by [MENTION=1876393]Monfro[/MENTION] which will take care of all that for you and is based on this ROM http://xdaforums.com/showthread.php?t=2791580

In terms of internal storage performance - yes you will see a boost. In terms of battery - the difference is probably marginal. I would say check for any apps causing wakelocks.
[Nexus 7 Android Development] numus:
So you just flash the rom with f2fs and it takes care of everything? I thought there was some kind of prep you had to do.
[Nexus 7 Android Development] bshiznit:
--Dupe post--
[Nexus 7 Android Development] bshiznit:
You will need a recovery that supports F2FS recommend TWRP 2.7.1.1 http://xdaforums.com/showthread.php?t=1779092 then you will want to backup your stuff and move it all OFF the tablet and format /data and /cache to f2fs in the recovery. You will lose data...
[Nexus 7 Android Development] numus:
Nevermind... I figured it out... Gotta get be usb-otg since I don't have a download folder anymore :p
[Nexus 7 Android Development] T_L_O_T_D:
when i want to flash got this error:

zip signature verification failed: 1

use TWRP: v 2.7.0.0

any idea?
[Nexus 7 Android Development] bshiznit:
Try turning off zip signature verification... Also be sure the MD5 of your download matches the MD5 in the OP :)
[Nexus 7 Android Development] Domino5:
I keep loosing root with any stock rom can you recommend me alternative to supersu? Or how to fix root on stock roms
[Nexus 7 Android Development] bshiznit:
All seems OK here. Any particular app?
[Nexus 7 Android Development] ffejy462:
No issues with losing root either. I highly doubt that SuperSU is the problem...
[Nexus 7 Android Development] Domino5:
SuperSU show binary error message and every app lose root access. Its strange because everything works fine for couple of days and then this binary error. I tried to flash SuperSU.zip but it dont fix root and i need ro reflash whole rom and then newest SuperSU and root will be fixed... But only for couple of days. Anyone have this issue?

It happened on every kernel i tested (stock, oxydo, M-kernel and lean kernel)
[Nexus 7 Android Development] twics:
I'm getting itchy fingers been a long time since iv flashed something ?.
[Nexus 7 Android Development] bshiznit:
Same here! Plus my daughters have been using my tablet for all their goofy doll, dressup and fairy games cuz my oldest daughter's 32 GB tab needs a new motherboard :( My bad the freakin USB cable was loose to begin with and came out during a bootloader flash. OOPS.

Not sure how much more official images we'll be getting from Google - if any - for this device. Still I do have that build box in my basement and wouldn't mind compiling!
[Nexus 7 Android Development] twics:
Well I shouldn't complain really cause everything is working good, but the only thing I've noticed lately is the battery seems to drain a little quicker than normal, but that could be the age of the battery.
[Nexus 7 Android Development] bshiznit:
I agree on the battery thing... Could be 4.4.4 but good point my current tablet just turned 2

At least you didn't break one of your tablets!
[Nexus 7 Android Development] Luigiesin:
That's weird.. My battery is insanely good! But once again, I'm using Franco kernel.. So idle battery is amazing... I can have it on idle for days! Maybe you should try it... It's even smoother than stock.
[Nexus 7 Android Development] cpvm:
Where can I get franco kernel for f2fs?
[Nexus 7 Android Development] bshiznit:
Took me a sec to find it - here you go!

can someone post download link for TWRP 2.7.1.1?

I can't able to flash any of this, it gets error 7, I am using philz touch (latest) so probably that's the issue.
[Nexus 7 Android Development] bshiznit:
http://techerrata.com/file/twrp2/grouper/openrecovery-twrp-2.7.1.1-grouper.img

Also be sure to check MD5 sums...
[Nexus 7 Android Development] jazzespresso:
interesting, I used twrp-2.7.1.1, still nothing....you may be right I need to check MD5, maybe I need to re-download...

I am testing some stuff, so I need to switch back to pure stock deodexed ROM...
[Nexus 7 Android Development] jazzespresso:
i can't get it work, checked MD5, and I got wrp-2.7.1.1-grouper installed, and flashing...nothing happens...strange part is it does not throws any error this time, but when it reboots, it tells me no OS....too bad that this is the only stock deodexed ROM, which I needed it...oh well...maybe need to find a way to flash this using latest philz touch recovery!
[Nexus 7 Android Development] twics:
Wow......well before flashing Franco Kernel I was using M-Kernel a67, if I left my nexus alone without using it, it would last just a day or just over, last Saturday I used it for about ten fifteen mins maybe more and pop out to a BBQ, it is now Tuesday 18:14 I have just picked it up expecting it to be flat but no it still has 48% battery left three days, now that's what I call a Kernel.
[Nexus 7 Android Development] bshiznit:
Yup - I think Franco has double tap to wake and swipe to wake off by default? Wheras M-kernel they are on by default. Those features are battery killers :P
[Nexus 7 Android Development] twics:
Yes that's right and I had them activated, loosing them options is a small price to pay when it comes to having longer battery life IMO, however them options do come in handy at times. [emoji4]
[Nexus 7 Android Development] bshiznit:
Agree 100% - I'd be curious to know which is less draining on the battery and just use that one. Perhaps I'll ask around.
[Nexus 7 Android Development] twics:
That would be [emoji41]......if you have the time please do.

[Nexus 7 Android Development] twics:
Ummm I'm guessing even if you turn off double tap to wake and just keep swipe the same battery drain will occur, I'm no dev but I just got a hunch loooool ?

If I had the time I'd test it myself.
[Nexus 7 Android Development] bshiznit:
Good news - I replaced the motherboard in my daughter's tablet that I had hosed the bootloader on and it is now working! If anyone ever has any questions about this process feel free to PM me. I bought the part on eBay http://www.ebay.com/itm/ASUS-Nexus-...crews-and-lcd-cable-guaranteed-/121393339106? - the seller was very friendly and offered that I contact him if any issues installing the new part.
[Nexus 7 Android Development] Ralphyralph:
So using Franco kernal on this ROM is the bomb? Downloading now...
[Nexus 7 Android Development] ffejy462:
Been using Franco kernel on Nexus 7 and gnex for a couple years now and never had a problem. There is some color banding in some cases, but not a big deal.
[Nexus 7 Android Development] Snuzzo:
For those who wish to try it

http://vp-zp.com/snuzzo/kernels/grouper

It uses an AnyKernel installer that pairs up with existing ramdisks. This can be used on either f2fs or ext4 ROMs.

[Nexus 7 Android Development] Monfro:
I think it will be good if you create a thread here on XDA for your kernel.

Then maybe link users to your site for download
[Nexus 7 Android Development] twics:
Not sure if this is a bug or not and I don't know if its been mentioned, but when I'm in my app drawer the background is transparent and I can see my wallpaper but if I rotate to landscape the background goes black is this a bug?
[Nexus 7 Android Development] ffejy462:
If you're using the stock launcher then it is. I've always used Nova launcher... If I remember right, didn't the rom come with the stock launcher (launcher 3) and the google now launcher (or whatever it's called)?
[Nexus 7 Android Development] Snuzzo:
Don't mean any disrespect. Most users that have been following my work already know where to obtain it.

Hi bro... I flashed ur ROM thru CWM.. from stock 4.4.2 version. build is KOT49H..

Try that out and then updating through Play Store.

I tried this kernel but had to go back to m-kernel cause when charging it would only get to 83% and not fully charge.
[Nexus 7 Android Development] Snuzzo:
Quite odd but thanks for the feedback. [emoji4]
[Nexus 7 Android Development] twics:
It worked pretty good on gaming MC5 and general use very smooth, just the charging issue I had.
[Nexus 7 Android Development] Monfro:
From my test Snuzzo's FunkyKernel works really well: smooth, consistent, fast and with great battery life.

The kernel has also wake screen gestures.

No problems at all, only positive thoughts from my experience (on f2fs, using m-kernel ramdisk and trickster mod)
[Nexus 7 Android Development] ffejy462:
Been a long time Franco kernel user, and so far this is great. Love having dttw like my g2, and 1.6 ghz is fantastic! M87 was good at making a lot of heat and eating battery and Franco kernel had some color banding issues.
[Nexus 7 Android Development] T_L_O_T_D:
how to enable usb otg?
[Nexus 7 Android Development] ffejy462:
You should be able to just plug it in.... You will need to unmount before removing although. I haven't used otg with my Nexus, but with my g2,you just plug it in and it recognizes it automatically.

You may need to mount it in twrp if you're talking about using otg in twrp.

Edit: now that I think of it, some devices aren't supported regardless of os version etc (Amazon Kindle Fire HD comes to mind; even with up to date twrp and cm 11) I'm not totally sure if the Nexus 7 is...
[Nexus 7 Android Development] T_L_O_T_D:
Since using stock rom when i plug in usb stick it doesn't recognized it
[Nexus 7 Android Development] bshiznit:
Try the stick mount app from Play Store... I lost my OTG cable so cannot test
[Nexus 7 Android Development] bshiznit:
No weird charging thing for me. Running great...
[Nexus 7 Android Development] ffejy462:
I'll plug my otg drive in tonight and give it a whirl... I have to say, otg drives are really handy. Mine has (I'm not sure if they're all this way) one side that's micro usb and the other is regular USB. It's about 3 cm long and holds 32 gb. I think it's even waterproof...

[Nexus 7 Android Development] ffejy462:
The OTG drive mounted and was usable in twrp, but apparently there's no native otg support. Using stick mount app by chainfire from play store works perfectly. You can navigate the OTG drive using a file explorer.

[Nexus 7 Android Development] jazzespresso:
yeap...I was never able to flash either odexed/deodexed ROM....no idea why so..I tried twrp-2.7.1.1, did not do any help, philz touch, did not work either.....

strange part of all these is I can able to flash any other custom ROMs (CM11, SlimKat, etc..)
[Nexus 7 Android Development] bshiznit:
Nice! In for two...
[Nexus 7 Android Development] bshiznit:
Hmmm - mine is just the system.img from the factory image unpacked, rooted, busyboxed and then packed into a flashable zip using [MENTION=673068]dsixda[/MENTION]'s kitchen. So the updater-binary and updater-script may be a little more old school in the zip than with some of the other compiled from source ROMs. I haven't really heard many users having flashing issues despite this though.
[Nexus 7 Android Development] Crossvxm:
Stock doesn't support USB OTG but almost 80% of all other roms do...lol.

---------- Post added at 10:54 AM ---------- Previous post was at 10:48 AM ----------

I'm assuming its because of the bad restore. Not my fault the flashing of the system.img thru fastboot caused a huge hangup in my RAM. That's probably why, maybe the ram is too little to help push the file...?
[Nexus 7 Android Development] jazzespresso:
not blaming your stock ROMs really....I just found it quite strange...but good point you got there about updater-binary and updater-script, that's only thing I think about it...
[Nexus 7 Android Development] twics:
I didn't have any issues flashing this ROM odex or deodex I'm using odex now no issues for me. Also I'm using Twrp 2.6.3.0 recovery.
[Nexus 7 Android Development] jazzespresso:
hmm....have not tried with Twrp 2.6.3.0 recovery....I may give a try to flash using Twrp 2.6.3.0 and see if it works...
[Nexus 7 Android Development] bshiznit:
Worth a shot! Also check the MD5 of your downloads. Whenever I flash a bad download it always hangs on the boot animation like you guys have been describing...
[Nexus 7 Android Development] jazzespresso:
MD5 is good....I doubled check :D

I am making nandroid backup now, in case something goes awfully wrong, i can revert it back :silly:
[Nexus 7 Android Development] ffejy462:
I completely forgot, but I think 2.7.1.1 was buggy (apparently the twrp team never fixed it, and that was a few months ago). Go back to 2.7.1.0, and it should flash fine.
[Nexus 7 Android Development] jazzespresso:
really?? that could explains why I could not able to flash it...I was trying with 2.7.1.1..
[Nexus 7 Android Development] bshiznit:
OH YEAH. I remember flashing that recovery and being like - OK WTF. If that is the case we should report it and ask to have the download pulled. Good call there.
[Nexus 7 Android Development] ffejy462:
Maybe they've fixed it since then. I'll flash 2.7.1.1 and try to flash something else to see if it's fixed. It is still available.

Edit: Well, I think it's fixed. Downloaded and flashed 2.7.1.1 via Flashify. Booted into recovery to verify. Booted system, flashed Franco kernel via Flashify. Booted to recovery and flashed snuzzo's kernel. Wiped Dalvik and cache. Booted system. Booted back to recovery again. Wiped cache and Dalvik. Flashed this rom. Wiped cache and Dalvik. Booted system. Flashed snuzzo's kernel via Flashify and enabled xposed framework, then rebooted. I didn't make and restore backup or clean flash a rom, but I think it's fixed. I know 2.7.1.1 was broken a while ago, but I think they've fixed it since. Maybe it was a bad upload on their part....
[Nexus 7 Android Development] jazzespresso:
yeap that's it...twrp 2.7.1.1 is bad one....but once I switched to 2.7.1.0 or any lower version it is OK, I did flash deodexed ROM just fine.

you may mention it to on OP post to not to use 2.7.1.1
[Nexus 7 Android Development] ffejy462:
Looks like they may have fixed it. Read my post above yours. I flashed 2.7.1.1 and I didn't have any issues. You probably updated your recovery when it was still buggy. The same thing happened to me and I was on cm nightlies at the time.
[Nexus 7 Android Development] ffejy462:
FYI:twrp updated to 2.8.0.0. http://www.teamw.in/project/twrp2. I flashed using flashify.

Edit: Updated to 2.8.0.1
[Nexus 7 Android Development] Luigiesin:
Hey guys.. So I haven't updated Firmware in a long time... Where can I get a firmware package, no wipe, no stock recovery? Basically a package to just update FW without having to lock bootloader or wipe data.

My N7 is so freaking laggy I can't get anything done.. I'm sure it's just a FW update I need.. Thanks!
[Nexus 7 Android Development] ffejy462:
The latest from Google is 4.4.4. If you have a locked bootloader and stock recovery, just take the ota. Your app data (if user chooses) is backed up by Google and restored after a wipe. Personal files (music, pictures, documents, etc) can easily be backed up to a cloud service or a pc.

Unlocking the boot loader, rooting, and installing custom recovery isn't that painful. Considering your lag issues, a wipe (and a different kernel) is probably a good idea.

Other than taking the ota or manually flashing a stock rom, I'm not sure how you could update. You could, I suppose, push the system img via adb, but imo you might as well unlock, root, and flash custom recovery, then this rom.
[Nexus 7 Android Development] Luigiesin:
I'm unlocked and rooted of course... I just need the FW with no wipe and no lock. Also I've been on Franco kernel since the beginning. It was really smooth until 4.4.4 which leads me to think is a FW issue more than anything else... That's the only thing I have not updated, the firmware.
[Nexus 7 Android Development] bshiznit:
Can you clarify firmware? Are we referring to the bootloader or the system partition or something else?
[Nexus 7 Android Development] Luigiesin:
The actual firmware.Zip that comes in the package.
