Wow I just flashed this f2fs ROM and its blazing fast!

I only got this tablet a week ago and it was unbearably slow on any ROM using ext4. Switched to f2fs with rastapop and m-kernel and it was much better, now this is ever faster.
[Nexus 7 Android Development] miqz:
Finally can change my grouper to f2fs...damn it's so fast and better than ext4...finall i can feel smoothness again on lollipop
[Nexus 7 Android Development] agent00f:
Possible to dirty flash this over Slimkat 5.7 (4.4.4) already running F2FS?
[Nexus 7 Android Development] BlueKnightedDragon:
No you must clean flash or you will have issues.
[Nexus 7 Android Development] thefunkygibbon:
good god. I've just installed this cleanly over on my n7 and now it doesnt boot past the black google logo. any ideas?
[Nexus 7 Android Development] jamminjon82:
More info? Like which version, on f2fs, did you check md5?
[Nexus 7 Android Development] BlueKnightedDragon:
If you flashed the f2fs version, did you convert your system, cache, and data partitions to f2fs before flashing?
[Nexus 7 Android Development] Reiven89:
Anyone know why Camera is not working? I use a lot Skype and right now i can't use it since the calls&videocalls doesn't start, also facebook app force closes without any message of crash

ps: i have not updated to the latest freak slim version....maybe this have been fixed?
[Nexus 7 Android Development] :
Bad news :/ ...My laptop is broken so I don't know when I can upload a new build
[Nexus 7 Android Development] amangupta53:
Well, this sounds bad. Hope you get you laptop fixed soon.
[Nexus 7 Android Development] ivicask:
Okay i need some info/help, i cant get mine nexus to work properly, i flashed latest recovery openrecovery-twrp-2.8.2.0-grouper.img, converted partitions to new F2FS it botoed and all, but it works TERRIBLE slow, and also my partitions are locked somehow, any app i delete, it returns after reboot, i cant apply ad blocking because it says my data/data is FULL (its not), i cant even push hosts directly to system via recovery i get write access error.

Does anyone has ANY idea whats going on because im going crazy already!
[Nexus 7 Android Development] amangupta53:
By the looks of it, your /system partition is full. Seems some sort of bug really. Have you tried formatting it to f2fs from twrp again? (and you have the right Rom from op)

Btw, I have the same 2.8.20 recovery and worked fine.

Your experience does shed some light of the recurring problem with us N7 users. The system lag when storage gets full. Seems it is still present with f2fs.
[Nexus 7 Android Development] PrizmaticSmoke:
Most full GAPPS packages won't fit on /system with F2FS, it appears to use up more space than ext4. Just use a smaller GAPPS package to avoid this, you'll need to wipe system in recovery, then re-flash the ROM and GAPPS.
[Nexus 7 Android Development] ivicask:
I already removed lots of apps from Google apps zip before flashing it, so how come nobody else got this problem, nobody else flashed full Google apps? Also that doesn't explain why my system seams write protected, I deleted apps and freed 15mb from system, after reboot apps are back and system again full..

Well i Will try reformat partitions, and delete as much of apks I don't need from rom and gaps and see if I have luck this time, thanks for ideas, will report back tomorow.
[Nexus 7 Android Development] BlueKnightedDragon:
Did you wipe the partitions before formatting?
[Nexus 7 Android Development] ivicask:
Hm..think not, why is it that necessary if I'm formating partition, it automatically wipes all data...?
[Nexus 7 Android Development] BlueKnightedDragon:
Idk if it is necessary it's just a suggestion
[Nexus 7 Android Development] ivicask:
Maybe your right, if it only converted partition without clearing data it may explain the bug I have...Damn spending too much time with Windows, same logic doesn't apply here I guess, thanks for good tip, will try tomorow as I said :)
[Nexus 7 Android Development] SkOrPn:
Anyone else having issues with Tapatalk Pro working? Yesterday I went to use it and it FC'ed, so I kept trying, uninstalled, re-installed and it kept on doing it. So, I reflashed the ROM and all my files, gapps, moab etc and it still force closes. However, it only seems to force close on the second try and every try after that. During the very first try, after install, or after fresh rom install it works fine. From the second Tapatalk launch onward it just force closes.

Probably something to do with alpha 8, since it worked fine on alpha 7?

EDIT: OK, it must be SlimLP at fault for my Tapatalk woes, just tried a old tapatalk apk from 2013, one from mid 2014, and the version before the latest, and all four versions are doing the exact same thing. Interesting.
[Nexus 7 Android Development] secret.animal:
I'm not having this issue with this ROM, but the same issue on cm12 alpha on my phone.

Don't know what is going on. It was working before then after trying different ROMs. It failed, only fix I found was just clear cache after each use.

That seems to allow it to work for the time.
[Nexus 7 Android Development] SkOrPn:
Yeah, clearing cache works in a pinch. Weird though that I can't get it to work and weirder still is the fact that I do not remember it doing it on alpha 8 when I first installed it and I am pretty sure I used it right away.

A scratching my head moment for sure, lol... I am almost wanting to re-download alpha 8 but think I should just wait for alpha 9 or 10 and try it again then. The alpha 8 md5 was fine though, so going to wait for the next release.
[Nexus 7 Android Development] tamanaco:
Two days ago I installed the SlimLp 5.0.1 F2FS ROM and PA GApps Micro 5.0.1 Beta1 on my N7 2012. So far this combination has given new life to my N7. I'm very happy with the performance of the NOVA launcher in this ROM and with the new features of Lollipop, but I would also like to see further improvements. After the installation of both of these components on the system partition I only have 40.4MB left in /system. I don't think this is going to be a problem unless I decide to install other 3rd party system apps like Viper4Android and Greenify so that Android does not kill them while not in use. I guess, as other have said, that F2FS takes a little more room, but this might resolved when the Nano release of PA GApps is released or by tinkering with GAapps configuration.

On the top of my list of things I'd like to see fixed... is a working Camera so that I can use Skype and apps like Barcode scanner. I would also like to see improvements in future releases for the following issues I found in my setup - I wonder if other have the same issues? - Pressing the power button sometimes takes a little while to wake up the N7 - Selecting shutdown or reeboot either via the power button or third party apps takes a while - The Google Play Store takes longer than usual to install more than one update at a time (it pauses... touching the screen appears to revive it) After a while of use the performance drops, but then suddenly it returns. (I can't find the process that might be causing this in the background). Also, don't know if this is WAD in Lollipop, but after I reboot I still find apps from the previous session (before the reboot) via the recent apps button of Android.

Btw, what were the Google developers thinking when they decided that the user needs to bypass two screens to authenticate if the lock screen is enabled. Is there a 3rd party mod around to fix this?

Well, so far so good... Thanks for this great ROM.
[Nexus 7 Android Development] Salamin1:
That really sucks!
[Nexus 7 Android Development] secret.animal:
Tablet no issues, though for the Tapatalk application. Maybe try fixing permissions on it. Not sure if it will work. But can't hurt.
[Nexus 7 Android Development] ivicask:
All okay now after i wiped system partition, whats really stupid is i did Factory reset from recovery, which DOES NOT wipe system partition, which is really stupid as it does on HTC M8 and all other devices i saw, i had to manually go and wipe system...
[Nexus 7 Android Development] Mdknight:
That sucks. I hope you're able to fix or replace it soon. (For your own use. I'm sure we can wait. The ROM is great as is already.) Good luck!!
[Nexus 7 Android Development] tamanaco:
Happy to report that Viper4AndroidFX_A4 v2.3.3.0 installs its driver in the /system partition of my N7 2012 and works fine on this ROM with no other settings changes necessary.. The /system storage capacity went from 40.4MB to 39.6MB.
[Nexus 7 Android Development] sTl2yk3l2:
Anyone else running this on the n7 have severe lag problems? I'm running the f2fs version and after a clean install it's good for a while, but then it's lagging as bad or not worse then stock lp. I guess lp just doesn't work on my decide good. The update made my tablet almost unusable. When I go back to 4.4.4 my runs lightning fast. Anyone else have these issues? Waking up from the screen being off is the worst, takes like 20 secs to turn on after hitting the button.

.=(.stryker.originals.)=.
[Nexus 7 Android Development] SkOrPn:
No its the best ROM so far for me. It's a completely new device now.

Sent from my Nexus 7
[Nexus 7 Android Development] tamanaco:
After the first install I also experienced lag problems, re-installing and using PA GAapps Micro and making sure to wipe and then change the partitions to F2FS helped. After rooting my N7 using Wug's Toolkit I also had to update Busybox to version 21 and had to make sure that apps that required SU were added to the SuperSU list of authorized apps. After a few reboots the performance improved, but once in a while I experience some lag. I have the same issue waking, shutting down and rebooting the N7. It also takes a few seconds, but sometimes it works like it's supposed to. I find that this F2FS ROM runs better on my N7 than KitKat, but it's not perfect yet... then again this ROM still an Alpha level driver. I also tried the "Official" Lollipop LRX21P stock ROM, but it was dreadful on my N7. Hopefully we'll see more improvements when the OP gets a working laptop.and tries to fix some of the remaining issues. I'm hoping to get a few more months of use from my N7, just waiting for the price of the N7 2013 32GB to drop further. The N9 is very expensive and I don't like its form factor for portability... anyway there is alread an iPad Air in the household.
[Nexus 7 Android Development] SkOrPn:
I wonder if the OP's laptop is something I can repair for him, or if he just needs time to do it himself?

---------- Post added at 11:27 AM ---------- Previous post was at 11:18 AM ----------

Yeah I think we need further improvements from TWRP. Every time I reboot to recovery from within a ROM it just hangs at the Google logo. I have to hold down the power button and go into bootloader. I tried re-flashing it several times but the hanging up remains.
[Nexus 7 Android Development] :
I need a little bit of money to buy a new monitor... Cause my display is broken. I think it's cheaper than buying a new one
[Nexus 7 Android Development] SkOrPn:
Well if you need any help with electronics hit me up in a PM. I will do it for nothing. I'm retired now, but that is what I do. At Intel for 10 years as a QA dept manager, with tons of electronics training. Then Sandia National Labs as a IT tech responsible for keeping several thousand computers running. I just built my own 2560x1440 IPS display, using various components off the internet, just because I can. Give me two dead laptops and I can turn it into one working laptop. That is how I got my nice laptop by buying dead ones for next to nothing on ebay and then repairing them myself by swapping chips, parts etc.

If it were my laptop I would just swap out the display, or buy a cheap 24" off of ebay and install the laptops mobo/tray on the back of it, lol. Build your own AIO pc.
[Nexus 7 Android Development] :
Thanks???? I'm looking for a 24 monitor but the problem is I have no money any more. I'm a student and spend my money for a moto g 3 weeks ago
[Nexus 7 Android Development] secret.animal:
Kudos to you brother. Being a student and this development.

Skorpn, I might hit you up with stuff like that.
[Nexus 7 Android Development] SkOrPn:
Gotcha, I know how it is being a student. Been there and done that. Now I am watching my Daughter go through the same troubles, and she's a Mother, Wife AND a full time College student in her 5th year... :good:

So, I understand...
[Nexus 7 Android Development] :
Great news .. Found a monitor. The display is crap but I can build . So I am able to push new builds
[Nexus 7 Android Development] SkOrPn:
Woa, you just made my day. I was bummed all day trying to think of a way to keep SlimLP coming to this device. I re-tried all the other roms over the last few days, and it is crystal clear SlimLP is the single best rom to ever have been flashed on my Nexus 7. Was preparing to flash alpha 7 here in a few hours.

Was also looking into figuring out a way for you to use my fast 4Ghz Hexa-Core Xeon machine remotely, but still have not looked into it yet.
[Nexus 7 Android Development] alan081954:
any chance of getting the camera to work?
[Nexus 7 Android Development] SkOrPn:
OK, just re-installed alpha 7 after trying every LP rom available, and all my apps fresh from the play store etc, and did so using a fresh clean install. I must say, I am now thinking about completely unsubscribing from all threads at xda and never flashing another ROM as long as I own this device. It works so brilliantly fantastic, minus a few little issues, that I do not want to ever risk losing this insane level of performance. And it took only two years of insane amounts of ROM flashing to find the proper setup...

Thanks freak_97 for finally discovering what my N7 needed :good:
[Nexus 7 Android Development] Niropa:
like pretty much everybody else who has tried this rom i have to agree that his is hands down the best rom ive tried in the past 2 years since i've had my nexus 7. thanks for putting the effort into making it. do you think its possible to make a similar rom/port to the moto G? that would be awesome to be running this on both my tablet and phone lol.
[Nexus 7 Android Development] BlueKnightedDragon:
The camera is working on Rastapop is there anyway to use the camera files from there to get the camera to work on this
[Nexus 7 Android Development] SkOrPn:
install rastapop, make a tb backup with data of the camera app, then copy your tb backups as usual for safe keeping. Then install SlimLP and restore the camera app? Would that not work?
[Nexus 7 Android Development] BlueKnightedDragon:
If anybody wants to try it I can upload a backup of the camera app from Rastapop
[Nexus 7 Android Development] SkOrPn:
I guess I can try it for you.

https://docs.google.com/file/d/0BwM4yt6h0OQ5VkF2VE56QUFqSEE/edit?usp=docslist_api
[Nexus 7 Android Development] SkOrPn:
Nope, its not working on SlimLP. Installed just fine but getting a force close when opening the app. Deleted its cache etc to no avail. Sorry...
[Nexus 7 Android Development] carlfinity:
I thought I read here somewhere that it was caused by the optimizations applied on this rom, not because of a missing app.
[Nexus 7 Android Development] blinde:
never mind...
[Nexus 7 Android Development] BlueKnightedDragon:
When you wipe your partitions there should be a repair/change option which allows to change to f2fs. Wipe and convert each partition separately or you could have issues.
[Nexus 7 Android Development] blinde:
Yeah I found those and managed to convert. Rom installed okay but I can't add google account. I installed Slim_full_gapps.BETA.5.0.x.build.0.x-427.zip.
[Nexus 7 Android Development] BlueKnightedDragon:
Use pa gapps cause people have issues with slim gapps http://xdaforums.com/showthread.php?t=2943900

You may have to do a full wipe to get it to work also remember to flash the newest super su for root
[Nexus 7 Android Development] blinde:
Apparently that MICRO MODULAR PACKAGE is only option to flash since there isn't other available links?
[Nexus 7 Android Development] BlueKnightedDragon:
Yes it has everything you need like playstore and google search
[Nexus 7 Android Development] carlfinity:
Use PA gapps for Android 5.0, it's the one that works even on dirty flashes
[Nexus 7 Android Development] thelangosta:
I used Banks' minimal 5.0 gapps the last time I flashed a ROM and they work fine too.
[Nexus 7 Android Development] LucentBirch:
Anyone else have the "miscellaneous" stuff popping up in battery stats? Thought they fixed that stuff before the official release? Although I can't tell if it's using any battery or not though,there's not any info showing in it except for " computed power use" and "observed power use"
[Nexus 7 Android Development] Salamin1:
I used to have it, but it disappeared after clean flashing the latest build. Maybe you have to do a clean flash again. Good luck!
[Nexus 7 Android Development] SkOrPn:
[MENTION=5373714]freak_97[/MENTION]

I been meaning to ask you what this OptiPop Optimization is? Is there something I can read more about it somewhere please? I tried searching for some info but all I find is your rom and some rom called OptiPOP ROM, and nothing specifically about optipop optimizations. Did you create these optimizations yourself?
[Nexus 7 Android Development] LucentBirch:
I keep having the location icon appear without turning location on... Anyone else?
[Nexus 7 Android Development] Salamin1:
Me too!
[Nexus 7 Android Development] carlfinity:
Same here, I guess its a known bug.
[Nexus 7 Android Development] mikeymesina:
For me, that disappeared after a reboot...
[Nexus 7 Android Development] liltbrockie:
Hi there.. did all of the above... worked great all fine... only problem was I could not add a google account... Play was not installed and I could not manually add a google account... i flashed this Gapps

Slim_full_gapps.BETA.5.0.x.build.0.x-427
[Nexus 7 Android Development] luckyrumo:
Maybe full is too large? Have you tried the normal or minimal gapps?

The normal ones work fine with my current rom.
[Nexus 7 Android Development] liltbrockie:
Changed to this gapps and it worked:

Slim_mini_gapps.BETA.5.0.x.build.0.x-427
[Nexus 7 Android Development] SkOrPn:
Same here slim mini gapps works just fine.

Sent from my Nexus 7
[Nexus 7 Android Development] myxXx:
Hey try to install normal gapps... Thatvshiuld do the job. Dont install micro or mini gapps..
[Nexus 7 Android Development] Darrian:
I'm also going to recommend the PA gapps. I haven't had any trouble with them.
[Nexus 7 Android Development] SkOrPn:
Anyone feel up to helping me update freaks newest alpha 9 build please? He gave me the newest build in a PM and then asked me to update it for m-kernel and all-f2fs but I can't seem to figure it out, even though I told him I would. He had to get some sleep for his school tests. This is his build of SlimLP alpha 9, so I think its the least we can do to try and help reduce the work load for him. I think all I have to do is update the updater script by copy/pasting the files from alpha 8 (?), but its not working on my Ubuntu 14.10. I copied over the newly created rom zip and twrp says it failed almost immediately. I used Ubuntu 14.10 to open, extract swap files, and re-compress the zip. I tried twice but both times it fails to flash and I do not understand why.

I can flash the new build successfully as-is, and then flash m-kernel a73 manually and it then works proper and boots up with /system as ext4 and both /cache and /data as f2fs, but that is not what freak_97 wants... Anyone have an idea as to what I am doing wrong? PM me if you want to help get this new build working while he rests. Again, its the least we can do.
[Nexus 7 Android Development] reade0871:
What are you trying to swap? The updater script can be edited and repacked to format /system f2fs no? When at a computer I can take a look
[Nexus 7 Android Development] SkOrPn:
Yeah, I thought I could just swap over the file but I guess not. Going to try just editing it.

EDIT:

OK, editing the updater script also does not work. I just opened the alpha 8 all-f2fs updater script (which works), copied all of the text, then pasted all of it into the alpha 9 rom's updater script. Slim seems to have changed something, or I need to only update specific lines leaving the rest as-is. Which is what I think I will try next, lol...
[Nexus 7 Android Development] reade0871:
Just edit and repack ensuring that mkfs is set to f2fs. Are you trying also to pack busybox and m-kernel a73 in ROM zip? I would try creating without and then manually flash a73 prior to first boot.

---------- Post added at 08:33 PM ---------- Previous post was at 08:20 PM ----------

Dumb question but are you resigning the zip? Are you getting errors when flashing or is the /system partition formatting ext4?
[Nexus 7 Android Development] SkOrPn:
Yeah, I was also copying the boot.img from alpha8 to alpha9 and repacking.. I am using Ubuntu to simply right click and tell it to compress into zip. Should I instead not extract and just try to edit the file while inside the open zip? I been right-clicking and extracting before editing it assuming it would just work.

OK, the new alpha 9 updater-script is much different then the alpha 8 one. That is why its probably not working. In fact, the entire rom package looks to be in a different structure. He did comment that alpha 9 is the biggest update so far, not counting 5.0.1.

Here is the pastebin of the new updater-script in alpha9, this is the one I have to edit to work.

Here is the updater-script from SlimLP alpha 8. BIG difference between both.

---------- Post added at 06:41 PM ---------- Previous post was at 06:39 PM ----------

I am getting the red word FAIL during flashing the ROM.
[Nexus 7 Android Development] reade0871:
This version seems to be using the android L block file structure. This can be seen most likely in the ROM zip. I'll look into it tomorrow but I know it can be converted to the traditional file structure and then the updater script can be fixed

Try this:

http://xdaforums.com/showpost.php?p=56957815&postcount=2760
[Nexus 7 Android Development] SkOrPn:
Yeah, browsing the Alpha 9 ROM zip it is clear it is structured differently. I guess I do not know how to edit the updater-script and I can only assume all previous methods/apps will no longer work. freak_97 never mentioned if I could post the ROM here, so I won't be doing that without his consent.

However, I am sure he won't mind if I give out the download link in a unofficial capacity via PM, so just PM me if anyone here wants to give it a try, or if anyone wants to try and get it flashing WITH m-kernel included..
[Nexus 7 Android Development] alwaysadeel:
beginning from Alpha-9 script here http://pastebin.com/NFg9AV3a

just open the Alpha-9 zip file, double click the updater script , it will open in some editor

Replace

with

and

with

Click save, the zip will automatically ask you to update itself.

I havent seen grouper fstab, it also needs editing for system, data and cache
[Nexus 7 Android Development] reade0871:
That will come from m-kernel a73 zip.. I thought he wanted to revert to old file structure and that's why I posted the link. Since most ROMs will package with the new block structure, your edits work better. Thanks
[Nexus 7 Android Development] SkOrPn:
OK, the first edit is listed twice in alpha 9 updater-script, so I need to replace it twice, right?

EDIT: OK, well I made the edits and it hung on the google logo. Now I am confused even more.. LOL, but the editing of the zip worked correctly this time, and the zip asked me if I wanted to update it. I wonder if I can download the original updater-script from SlimROM's repository and update that one?
