flashing from slimkat 4.4.4 - do I need to upgrade to Lollypop 1st??

I'm on Slimkat, F2FS and have downloaded this Rom (psyched to install).

went to TWRP (2.7.0 F2FS) did the wipe, installed the rom, it didn't take.

so I restored by backup and redownloaded the rom (maybe I had a bad download?).

but before I go through it again, maybe I didn't do something, like upgrade to Lollypop? or can I go from 4.4.4. to this rom by just flashing it?

sorry if nooby, but no answers in the thread.

thanks.
[Nexus 7 Android Development] SkOrPn:
Make sure your on TWRP 2.8.2.0 recovery and try again please.

Help?

Alright guys, I've been trying to go from unlocked+rooted stock Lollipop 5.0 to F2FS with Freak's SlimLP's Rom. A factory wipe to Lollipop sped up the device for a few hours, but then it returned to it's horrendously sluggish pace. So I thought I'd give a stock(ish) ROM and F2FS a try.

I've been trying to follow this post's steps and I keep getting stuck. Can anyone help? I soft-bricked my device twice, but thanks to the Nexus Root Toolkit I've been able to save my 2012 N7 wifi. My steps are:

Download latest version of SlimLP and PA gapps

Reboot into TWRP (2.8.2.0) recovery

Change system, cache, and data (one at a time) from EXT4 to F2FS, and then repair them (one at a time)

In TWRP, go to ADB sideload to push the SlimLP and then gapps via windows CMD

The last part is where I am stuck. The TWRP ADB sideload never starts, and CMD does not recognize ADB commands since my N7 is in recovery mode. I've also tried loading the files on the SD card, but those were (of course, should've known) erased when I formatted the partition to F2FS.

Where am I going wrong? Will flashing this ROM in TWRP convert the system, cache, and data to F2FS (meaning I don't need to format before flashing)?

Thanks for the help!
[Nexus 7 Android Development] SkOrPn:
Try doing what is in red above instead. Forget ADB sideload and just put the files back onto the device or flash directly from a usb flash drive using your OTG cable.
[Nexus 7 Android Development] Finner42:
Is the latest version of TWRP only required to get all-F2FS working? I managed to install this as data-F2FS without any trouble on an older version (2.7.1.1 maybe..), but am now thinking of switching to all-F2FS. Just to be sure, to do this, I would only need to format my system etc. partitions, and not the internal storage partition, so I should be fine downloading the ROM to the SD and it won't get wiped?

Also, does anyone know if Sykopompos's ART and VM build.prop tweaks will work on this? (http://xdaforums.com/google-nexus-5/general/android-l-developer-preview-discussion-t2795890/page624) I'm guessing yes, but just curious to know if anyone has tried already and been un/successful? And if there was any noticeable improvement?
[Nexus 7 Android Development] teh Phil:
Thank you!! I didn't realize TWRP had the MTP feature.

For others looking to go from Stock 5.0 to Freak's Slim Grouper with F2FS this was my process (It's really not as daunting as it seems):

If you haven't already, unlock and root your N7 with Wug's Nexus Root Toolkit. I cannot thank him enough, it is the most user-friendly and easy to use program I've come across on XDA. I soft bricked my device several times (formatted the partitions to F2FS and couldn't get the ROM and gapps files on to flash), and honestly thought I was going to be without a tablet for a while. No problem, the NRT took me back to stock.

Use the NRT to create a backup of your device. It will transfer the backup onto your PC for you. This isn't a necessary, but it's a nice safety net in case you mess up.

Download latest version of SlimLP and PA gapps

Reboot into TWRP (2.8.2.0) recovery

Wipe the system

Change system, cache, and data (one at a time) from EXT4 to F2FS

In main TWRP menu, hit "Mount", and "Enable MTP" if it is not already enabled

Drag the two zip files you downloaded into the TWRP folder

Hit "Install", find the "TWRP" folder

Select the Slim group zip and swipe to flash

Go back and select the gapps zip and swipe to flash

Reboot the system

Wait a few minutes to boot up

Set up the device as usual

Use the NRT to root (install SuperSU and Busybox)

The NRT will no longer be able to make an easy backup for you. Reboot into recovery again and create a backup in TWRP. Put in on your PC for safe keeping, and so you have a clean slate to return to in the future.

Enjoy!

Two notes:

I couldn't get the N7 to mount in Windows the first time. I reinstalled the drivers from ASUS and Google, and it worked. When it finally mounted I was not able to drag and drop the zip files - all that showed up was "internal storage", no folders. I rebooted into recovery and tried to mount again, and this time it worked.

Some people mentioned they were having trouble with the launcher. I selected the Google Now launcher during setup and haven't had any problems. I got an error about Google Text to Speech being unable to start during the sign-in process, but that went away.

The OTA Lollipop update slowed my tablet to a crawl, to the point that it was almost unusable. My N7 is almost TOO fast now, it's incredible! Here's an AnTuTu benchmark shortly after flashing. I think I was somewhere around 17000 on stock 5.0 and EXT4.

Thanks to freak_97 and the Slim group for the ROM, SkOrPn for the help, and all of the other developers in this subforum. You all rock!
[Nexus 7 Android Development] SkOrPn:
EDIT: LOL< I see you got it working... Good job

I just deleted a few minutes worth of text because you figured it out on your own. Yeah the new TWRP is MUCH better, in fact you should make it a rutine to always make sure your on the latest when you plan on doing things like this. They are always releasing fixes and adding new features and MTP was one of the best, next to built in f2fs support..
[Nexus 7 Android Development] idivorceyou:
Thank you! upgrading to the newest TWRP did the trick and I am happily on the rom and am about to now re-install my apps.
[Nexus 7 Android Development] heymoe:
Just an FYI post:

I installed SlipLP + LGapps + All-F2FS clean / fresh and noticed I was getting Google TTS errors / force closed messages. To fix this I just deleted the GoogleTTS folder from /system/app in recovery, booted back into L and then installed it from the play store. Everything seems to be working fine after that.

Sorry for the double post if this has already been mentioned.
[Nexus 7 Android Development] ChavitoArg:
This will be mi first ROM in months literally, and first time with F2FS so... cheers!
[Nexus 7 Android Development] SkOrPn:
Yeah, I just deleted TTS altogether and have not had a problem. Thought I would have errors doing that, but nope not a one and its been several days.

Good luck and enjoy the new device you will end up with after you get it running. It is so much more pleasurable then KK it just amazes me. Sometimes it is so much faster, that I have to do a double take to make sure its my N7.
[Nexus 7 Android Development] barakisbrown:
I am amazed by my journey with Android L. Started off with Google Release via sideload which was sluggier than molasses. I then upgrade to CM11 by euroskank and it was a excellent improvement. I then decided to see what the whole F2FS and this thing FLIES. Is this the same nexus 7 that I bought 2 yrs ago .. :)
[Nexus 7 Android Development] sTl2yk3l2:
Blahhhhh
[Nexus 7 Android Development] SkOrPn:
Yes, lol it is the same device, but only now it is FINALLY running the way it was originally supposed to. Lol, twice now I almost sold this device but now I finally like using it.

[Nexus 7 Android Development] carlfinity:
I'm getting used to seeing people getting amazed by how goood this rom is. To be honest, i stopped using the Slim rom for quite awhile, and here I am again, back to my first love. No regrets. :victory:

---------- Post added at 11:55 PM ---------- Previous post was at 11:51 PM ----------

Boy i'm lucky, I dirty flashed it and I didn't encounter any issues. I always do a reboot to recovery after flashing the rom, gapps & the supersu file.
[Nexus 7 Android Development] jdiamond7:
I am blown away. I had been putting off going to f2fs for awhile now but finally bit the bullet. Flashed slimlp with M Kernel and can't believe the difference. I'm pretty sure my device has never run this smooth even when I first took it out of the box 2 years ago. Antutu benchmark is over 23000.
[Nexus 7 Android Development] :
I am glad that I make so many people happy with this Rom...Thanks

What to prefer daily updates, an update every second day or when a new alpha is released ?
[Nexus 7 Android Development] shaman_Turtle:
For me,

Update when USB Stick available :o and weekly.
[Nexus 7 Android Development] idivorceyou:
for new update, the file does not say "F2FS", so I am reluctant.

is this the F2FS version: "Slim-grouper-5.0.alpha.0.6-UNOFFICIAL-20141202-0633.zip" ?

thanks,
[Nexus 7 Android Development] :
Yes it's the f2fs version in the f2fs folder but I am too lazy to rename the files
[Nexus 7 Android Development] SkOrPn:
Just take the UNOFFICIAL word out of it and rename it like so "SlimLP-alpha.0.6-F2FS-20141202-0633.zip" then you will know its the F2FS version.

---------- Post added at 11:18 AM ---------- Previous post was at 11:00 AM ----------

Yeah agreed, every few days to at least once a week for me.

This is clearly the best ROM on my device to date, so you made me happy too. :good:
[Nexus 7 Android Development] x3dnd3x:
Can I check, to try out F2FS, I just download the one linked by OP and flash it using Wug's toolkit. Is that right? :confused:

I'm on stock now.
[Nexus 7 Android Development] EvilDeadFan:
Guys, I've been searching all over.. But do you need a custom kernel for f2fs on this room as well? I followed all the steps forever i keep getting promoted for a password. I followed the posted instructions.. Must have missed something somewhere.

Flashed a F2FS Kernel, everything works. Nevermind. :)
[Nexus 7 Android Development] SiNJiN76:
Thanks for your very informative Post. Been away from the Grouper forum for quite awhile...and I was scratching my head when I saw F2FS. I failed a few times...and then saw your post....and then I won. :silly:
[Nexus 7 Android Development] bigmook:
No google search or google now in get install error 505
[Nexus 7 Android Development] carlfinity:
IMHO, every second day or weekly is good. Whenever you think that is convenient. Longer than that seems to be a long wait tho. I'm glad that you asked.
[Nexus 7 Android Development] Prof Peach:
If its a full wipe fresh install or changes warrant that, once a week is best.

If its a tweak or smaller update that can be dirty flashed without any issues I'm happy with every couple of days.

Real life comes 1st so I'm happy with whatever you give us. This LP is awesome.
[Nexus 7 Android Development] treesurf:
I decided to finally go f2fs and flashed this ROM for the first time. Holy crap is it fast! The animations were a little too dizzying for me, though. I had to go into the developer options and slow them down.

A top notch ROM here. Many thanks to the Dev!
[Nexus 7 Android Development] labrazil:
this is an excellent rom. my n7 has never been so smooth and fast. i have a question, what is the difference between the two gapps you listed for lollipop https://s.basketbuild.com/devs/RobbieL811/Gapps/L/? i am using the slim version.
[Nexus 7 Android Development] brooker88:
cant flash via adb? keep getting errors

EDIT* didnt notice it had MTP. Fixed. And SuperSU binary will not update, searched topic couldn't find a fix any solution? Tried both options. Fixed flashed v2.37
[Nexus 7 Android Development] EvilDeadFan:
Seems to work really fast, however my only thought is that Google Search cannot install. It just comes back with an error, which means no Google Now launcher.
[Nexus 7 Android Development] Crowmaster:
Just flashed this ROM and damn, its fast. Much faster than stock 5.0 (but i changed animations to 1x ;)). But a have one problem.. google play is almost all black. I flashed gapps from first post.
[Nexus 7 Android Development] :
Flash the L gapps and not the slim ones. The real black gapps are the main feature of the slim gapps
[Nexus 7 Android Development] zarac:
I am having the 'location icon bug' with this rom where the status bar icon doesn't disappear once activated.

Other than that the rom is absolutely perfect. My n7 never felt so snappy.

Coming from factory 5.0 - wiped everything and converted to all-f2fs. Used alpha PA gapps and had zero issues.

Great job!
[Nexus 7 Android Development] :
It's a general Lollipop bug
[Nexus 7 Android Development] brooker88:
So quick, curious as to what battery life is like compared to the other rom i was using so I'm going to test it out. Thanks for an awesome rom
[Nexus 7 Android Development] Crowmaster:
ok, any fix for google search not working? (error 505 while downloading from store)
[Nexus 7 Android Development] Poerger:
mh, I flashed the newest f2fs version of this rom and I'm impressed ... but I dont have root?!

(and yeah, I ticked the root box in settings :D)
[Nexus 7 Android Development] SkOrPn:
If you flashed SuperSU, then yes you have root.
[Nexus 7 Android Development] edy4sure:
Am I missing something in the installation procedure? I have done this:

- Wipe system, data, cache, dalvik cache

1. Flash the rom

2. Flash Slim gapps or L Gapps

3. Reboot

I've done this 3x and all I get when I reboot is, the Slim boot logo in a loop?

Please help? :(

[Nexus 7 Android Development] Darrian:
Very nice. My daughter's tablet is usable again thanks to this. I do wish it had the camera app though. Camera apps on the play store can't seem to use the camera now so I have no camera and my daughter loves taking photos, even though the camera is front facing and poor quality.

i thanks so much for your hard work on this!

can I dirty flash this? oh, wtf, gonna do it after backing up... if it doesn't work, then I'll do the clean install & all the wipes. It is just tedious restoring 50 apps and setting up emails, browsers, etc. (even with an update.zip created by Titanium backup, there is a lot of setting up I'd prefer to avoid)

will let you know about the dirty flashing effort later.

EDIT:

did not do the dirty flash. did a wipe after creating an update.zip with all apps n data. hopefully that will shorten the process time.
[Nexus 7 Android Development] webdroidmt:
Thanks for another new build, it seems to be running well for me. Looks like SuperSU is no longer needed as the built-in superuser is working just fine. Regarding the camera, just checked the Nexus 5 Slimpop thread and the camera is working on that device.

I also tested an alpha build of Vanir's Lollipop rom for grouper, which is pretty much CM based and the camera worked. Any ideas on why it's not working on this rom?

Mike T
[Nexus 7 Android Development] :
Maybe the toolchain breaks the camera.

I never use the camera on this tablet so it's not important for me. I will have a look if I have time for it

Tweaking question:

I occasionally activate "force gpu rendering" and "force 4xmsaa" which gives an antutu boost of approx. 500 points. Is this an OK thing to do with this rom? Any other performance tweaks we can try?

thanks!
[Nexus 7 Android Development] Prof Peach:
FYI build number in the latest upload shows .6 rather than .7 in case its confusing anyone.

Dirty flashed over .5 with only system wipe. Rebooted recovery. Flashed gapps. Rebooted recovery. Flashed custom kernel. Rebooted system.

All very smooth and fast. Didn't think I was going to like LP after the stock ota but this feels great. Many thanks to all involved.
[Nexus 7 Android Development] carlfinity:
Do it the old fashion way by downloading Stickmount or any similar app to make your USB OTG work. This works for me.
[Nexus 7 Android Development] Salamin1:
I've just dirty flashed the latest build after wiping cache and system and everything seems to be working perfectly fine, just as expected.

I have one doubt: whenever I swipe down to open the notification box, it opens the quick settings, as if I swiped twice. Is that a feature or does it just happen to me?

Thanks again for such a great rom!

Edit: I've just realized that the two-swipes-in-one thingy happens whenever I do it from the right part of the screen (if I pull down from the clock, for example). However, if I pull from the center or the status bar, I have to do it twice to enter the quick setting. So it was a useful little shortcut after all!

The ROM is very fast! But I found one bug i.e. location icon is not go away from the status bar. My location is off. Is it mean it stays my GPS on? How to fix it? Should I restart my tab? A quick reply will be appreciated.

I just flashed this afternoon ROM is very fast no issues benchmark just under 24000 which is amazing. I have no icon in the status bar. Location is on and quick and accurate.
