[Nexus 6P Q&A, Help & Troubleshooting] jhs39:
If you want to keep your data flashing individually is necessary. My problem is that it isn't necessary to flash the individual pieces if you want to do a clean install but the instructions on XDA make it seem like it is. I've come across many people who followed those needlessly complicated instructions to do a clean install and ended up having problems. They follow those instructions because they trust XDA to give them the best information but I don't think that's happening in this case. The instructions should include the easy way first and then the complicated way in case the easy way doesn't work or you just want to do it the hard way for your own educational benefit. Making things more complicated than they have to be doesn't make sense to me--particularly when you are dealing with people who might not be comfortable entering fastboot commands on their computers. Everyone who roots their phone isn't a techie or a programmer or a developer. Some people just want the simplest solution to get from A to B rather than a step by step lesson in Android flashing and architecture.
[Nexus 6P Q&A, Help & Troubleshooting] b-droid:
Yep, I usually remove the "-w" switch from update command and run the flash-all.sh file from terminal. It really is an idiot-proof way of flashing the OS. Although this time around, fastboot was unable to flash boot.img and system.img files. Using individual commands didn't work as well. I just got an "file size too large" [paraphrasing] error. So I Googled and found out a switch to change the size of some sort while running the "flash boot" and "flash system" commands. I think that's the culprit. I also think factory reset won't do anything and I would have to flash the OS.
[Nexus 6P Q&A, Help & Troubleshooting] jhs39:
What does removing the "-w" switch from the update command do?
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
the -w switch is there to wipe data. removing it with a text editor before running the script prevents the update from wiping your data... basically a dirty flash
[Nexus 6P Q&A, Help & Troubleshooting] jhs39:
That's what I suspected. But you don't think a clean flash might not fix your issue?
[Nexus 6P Q&A, Help & Troubleshooting] v12xke:
Well, consider trying FlashFire before the nuclear option. Also use FF to look at your individual partition sizes and we can compare. Try flashing the system partition only in FF (from your current build number of course). If that doesn't work, try using the new N4F26J (full image, not OTA) and choose boot, system, & vendor only. If this does not normalize the size of your system partition then I think formatting them is the only way. From ADB, fastboot format cache, system, userdata first, then run flash-all, leaving the -w switch in place. Good luck!
[Nexus 6P Q&A, Help & Troubleshooting] b-droid:
-w switch wipes internal storage not the data partition. I believe dirty flashing is about overriding a new ROM on top of previous one without factory reseting or wiping dalvik cache partition, right? It can be done outside of the -w switch using recovery.
[Nexus 6P Q&A, Help & Troubleshooting] bjartskular_257:
Try wiping your cache partition.

I had the same issue on my N6 and a factory reset fixed it. It took it like 10 minutes to complete the reset, all of which was spent formatting the cache. Rebooted, went through the setup process, checked the storage use in settings, and it went from 35 gb to 3.6 gb.

Maybe there is something wrong with the cache partition in the 7.1.1 factory image, as I have always individually flashed the partitions and until now never had a problem.
[Nexus 6P Q&A, Help & Troubleshooting] Yamalito:
My girlfriend had the same issue, I formatted the userdata and cache with fastboot while the phone was in bootloader mode.

The problem was solved
[Nexus 6P Q&A, Help & Troubleshooting] dratsablive:
I never use the flashall.sh script. In my linux install (Fedora 25) it tries flashing the system.zip file instead of unzipping it first. Also I only flash

boot

system

vendor

I will flash the others if anything has changed, but I never flash the cache.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Awesomeness_1307:
So, anyway, I just installed Cyanogenmod 13, which is amazing, BTW. Thanks to [MENTION=5153662]Android-Andi[/MENTION]. Also Happy New Year to you. I have a few concerns and issues. Before I start, I would like to say that I installed this ROM with the following modifications:

1) Xposed

2) PurePerformance X

3) Kernel Aduitor

4) L Speed

5) Dhollmen Kernel

6) SuperSU

7) BusyBox

8) ViperFX [NOT V4A MK MOD]

Issues:

1) After installing Dhollmen Kernel, the lockscreen seems to be stuck in landscape mode. It's not a very big issue and I can live with it, but I would like some fix if possible.

2) IRS files won't show up in the Convolver section of the settings in ViperFX. The ViperFX folder doesn't even show up in the Cyanogenmod File Manager. I even tried creating the folder manually. Doesn't work.

3) The official Facebook app won't work. It starts, lags a whole lot, and then crashes. Is Facebook really that harsh on our tablets? Am using Facebook Lite for now.

4) And finally, this is the issue that kills it for me and I will have to change my ROM if this doesn't get fixed. MOBILE DATA IS NOT WORKING FOR ME. I am getting a signal and when I switch on mobile data, nothing comes beside the icon on the status bar. No 'E' or 'H' or 'H+' or '3G'. Nothing.

I would really appreciate anyone who helps with any of these issues, especially the last one.

Happy New Year to everyone on XDA.

I would have two questions:

1. Does SlimRom include privacy functionality like "Privacy Guard" from LineageOS?

2. Does encryption work properly in this custom rom?

Can't seem to get the download link. I don't receive the email. Can you upload it somewhere else?

Sorry , I did not tested , you have to test that .
[G4 General] dianxxyyzz:
Ok . I just reuploaded to another hosting
[G4 General] dianxxyyzz:
No problem . That was because video drivers . I included all video drivers and you ready to go :D

I just reuploaded
[G4 General] steadfasterX:
I believe this thread should be moved to android development?!
[G4 General] kessaras:
maybe. we don't know. it was my suggest. you see , lineage os unofficial was moved in general from forum admin , so i didn't want to suggest a new thread where it could be a problem.

besides he made it correct, he set the devdb information so it appears in rom section :good:

And since he is the only one and slim doesn't have a official thread in g4 he can make it more fancy :p

he can put logos, pictures...etc. Maybe he got bored haha, but its working from what i saw when i flashed it.
[G4 General] dianxxyyzz:
I can say , yes you have Privacy Guard manager , It must be enabled from Developer Option .

I did not encrypted my phone , you have to check that .
[G4 General] steadfasterX:
Many thanks for providing another current MM ROM!!!

I still believe that only MM can work great for this device atm. Until N is officially released by LG at least.

So thanks keeping MM alive ;)

Anyone tested device encryption with this ROM?

[G4 General] dianxxyyzz:
Thank you .

I did tested . It works
[G4 General] Deleted member 7812879:
Tested the encryption. Unfortunately it has the same lock screen issue as the LineageOS 13 rom.
[G4 General] dianxxyyzz:
You mean you can not unlock the screen when phone is crypted?
[G4 General] Deleted member 7812879:
Yes, exactly.
[G4 General] dianxxyyzz:
I saw this one time , I tought I forgot the pattern .

I do not keep my phone encrypted . I just need a fast room with a better battery , by the way I'll upload in 1-2 hours a new version that has a faster startup cause I fixed the problem with the flashlight that disappear from quick settings . Wll post here when will be uploaded , now startup speed is very good . I like this rom simpel , long battery life and fast .For me works very good is what I use every day . I'm sorry encryption do not works , I have to see if was fixed in Lineage OS ,and I will fix too , if tehre is a fix .Thanks for testing
[G4 General] dianxxyyzz:
have you tried the fix from this link ? https://www.reddit.com/r/cyanogenmo...ing_default_disk_encryption_password_in_cm13/

to change default password for decrypt
[G4 General] Deleted member 7812879:
I am new to Android and I am astonished that most people using custom roms do not seem to care about encryption. One has to be aware that not using using encryption makes it very easy to download all the data from an unlocked device (just boot directly to TWRP or via fastboot). One normally stores a lot of personal information within a smartphone: photos, contacts, password logins, notes, ... Even if one does not care about this, one should at least consider the fact that one puts at risk the personal information of ones friends, family members or work colleagues (contact information, photos).

[MENTION=5545101]steadfasterX[/MENTION] posted a workaround for the CM 13 rom: [TOOL][TWRP ZIP] Lock screen fix for encrypted devices.

It seems SlimRom shares the same code to handle the lock screen for an encrypted device and thus shows the same symptoms. I was hoping SlimRom would have a definitive fix for this issue.
[G4 General] dianxxyyzz:
Yes , of course encryption is very important , I'm just trying to see how fix it .

If it was fixed in CM13 I will fix it for sure . Saying that I just never user encrytion in my phone and I never knew it dnt works in cm 13

You dnt need encryption when you use a recovery that has minimum options .

-clear cache

-factory reset

-reboot bootloader (that also do factory reset before entering bootlaoder mode)
[G4 General] :
Unfortunately there is no fix in CM13 at the moment. The workaround of [MENTION=5545101]steadfasterX[/MENTION] disables the gatekeeper libraries.
[G4 General] steadfasterX:
And this is bad because...?
[G4 General] :
You mean when you use a minimum recovery, one cannot access the data on the phone.?

That's not true, simply:

1. connect usb cable

2. boot phone in fastboot mode (press and hold (at the same time) the Power and Volume Up keys)

3. boot TWRP on the smartphone with a TWRP on your computer with fastboot: fastboot boot [path to twrp image on your computer]

4. download all the data from the device

5. while your at it, disable any password/pin protection by deleting some files

6. reboot the smartphone

7. use the browser in the device and see where the smartphone owner is already logged in

8. ...

---------- Post added at 10:32 PM ---------- Previous post was at 10:29 PM ----------

Never said this would be bad ;) I my opinion it is better to use encryption with this workaround then no encryption at all.

At the moment I do not have enough knowledge to assess whether not using the gatekeeper libraries is a security risk or not. Even you mention in your post:

.
[G4 General] dianxxyyzz:
You can also hope the one who stole your phone is not a andorid expert and he will just choose to do a factory reset , so you can help him doing this , bu using a custom rom that every startup display this message :

"Dear thief , thank you for let me without my dear phone please press below 'Factory Reset' button so you can clean the phone and happy start using it .

I'm a good man so I customized and spend 2 weeks to compile this rom just to be easy for you to have a clean startup and you to do not lose time searching how to boot my phone in recovery mode .

Have a nice day and enjoy my phone will be clean after you push 'Factory reset' "

:))
[G4 General] :
Lol :)

Probably you are right that 99.99% don't know how to do this but I personally like to lock my house ;)
[G4 General] raptorddd:
no h811 support.?
[G4 General] dianxxyyzz:
Yes ... sorry this is just for h815 . I do not own a h811 . I can compile one and make another post for h811 cause they are very similar , but the testing must be done by users ,I know it will work for sure but I'm not the one who can see it working cause I dnt have a h811 ...
[G4 General] dianxxyyzz:
Ok , that's great . thank you very much , I'm implementing now .great !
[G4 General] dianxxyyzz:
I can say ,,, You can see... that ... you have slimport working , laser camera working , the phone for me stay with 100% battery after 3 hours I unplut it from charger ,....so I think you 're a little happy , and after I'll implement the encryption fix , maybe you'll be more happy :D :D :D :D
[G4 General] dianxxyyzz:
Ok , encryption is fixed , I switched from vendor hw encryption to software .

Everything is fine ,works like in CM/Lineage official builds for N5 .

Will upload in half a hour , will let you know when new version is up .
[G4 General] dianxxyyzz:
Link updated , you must really try this rom .

I'm not affiliated with any hosting ,if you know the way it can be uploaded to androidfilehosting or any other specific hosting I agree will all

[G4 General] dianxxyyzz:
Oki , thanks , I do now .
[G4 General] steadfasterX:
Thanks dude.

What exactly is fixed now in terms of encryption?

Which security patch level has this version btw?
[G4 General] dianxxyyzz:
Man , what you did in your twrp zip ,as I also read on google is the right way to do it.Thanks for pointing me in right directions .

Slimrom ecrytion was fine ,and was working but adding gatekepper library from vendor introduced the bug ,that do not let you unlock the phone.

Without that vendor so file , rom use his software encryption ,and that works .

So I did not added that so file from vendor ,and rom works like it was made to work.

The security patch is 5 november 2016 .

Thank you !
[G4 General] steadfasterX:
Sure. Lol. No problem. so from now on the lock screen fix is not needed anymore for slim. Nice.

thanks for your work.

Any chance to get newer security patch level?
[G4 General] dianxxyyzz:
Yes ,I will keep thia rom updated . is the one i use every day in my phone . have all features of device working ,slimport etc.

Battery life is better than in stock .

Will post updatea here . i 'm maitaining this rom.
[G4 General] steadfasterX:
Cool.

Just wondering why the patch level is from November and in other ROMs we have January sec level. :rolleyes:

[G4 General] kessaras:
did you try f2fs if it works ? i see in git that slim supports f2fs.

kernel support it already since a few months. the fstab is already set to recognise f2fs. [MENTION=5545101]steadfasterX[/MENTION] twrp already has f2fs support since a long time.

it must work. check once! if its working then slim is the first for our g4 with f2fs support, unless it has a bug :p
[G4 General] dianxxyyzz:
It works .You have mkfs.f2fs in bin. What do you want to format f2fs?
[G4 General] kessaras:
nice :D imma test it tomorrow! f2fs is faster. it just takes more time at 1st time to open/run something cause it caches everything, then it goes a lot faster than ext4.

~EDIT:

/data and /cache of course. system is always ext4
[G4 General] dianxxyyzz:
OK I format now my data using twrp and let you know
[G4 General] kessaras:
:good: :fingers-crossed:

if it works you have here now the best rom :D

f2fs + slim (debloated cm/lineage) + llama kernel ...... haha :D
[G4 General] dianxxyyzz:
Twrp 3.0.0.0 don't have f2fs . you have a link for a twrp that support this ?
[G4 General] kessaras:
yes since 3.0.2.+ we have f2fs

https://xdaforums.com/devdb/project/?id=16696#downloads

use any you want after 3.0.2.x

beta 5 is the best right now and unifies h811 and h815

---------- Post added at 06:21 ---------- Previous post was at 06:01 ----------

omg! fingers crossed. im booting now f2fs + slim + llama

---------- Post added at 06:29 ---------- Previous post was at 06:21 ----------

its working !!!!!!!!!!!!!!
[G4 General] dianxxyyzz:
Yes I just installed twrp 3.0.2.2 and formated data and cache f2fs .

I did a factory reset too.

All is working fine :)
[G4 General] kessaras:
there is only one small bug with f2fs to the default kernel.

it needs to fix the data partition which is 256mb. thats all.

but if we use llama kernel , that works out as a fix too. Thanks to [MENTION=5776465]genesixxbf3[/MENTION] for his kernel. Too bad thread is closed for no big deal or serious reasons, i hope he keeps maintaining his kernel for us for MM and N, both.
[G4 General] dianxxyyzz:
Yes , I see that , I pm you
[G4 General] kessaras:
[MENTION=5545101]steadfasterX[/MENTION] , [MENTION=5776465]genesixxbf3[/MENTION] , you guys definately have to see this.

your f2fs with slim rom sky rockets.

[MENTION=6051044]dianxxyyzz[/MENTION] , only check one thing for me cause im a little tired to format again.

if you reboot to recovery using the hardware keys , does it format back to ext4 ? It's a common bug in twrp and maybe we can ask steadfasterX for a fix.
[G4 General] dianxxyyzz:
No , all is fine you can boot into twrp using harware keys .Twrp just start like normal .

Twrp switch to ext4 only if you do "Format Data"

It is cool lol :)
[G4 General] kessaras:
niceeeeee !!! here im impressed too. the phone is like a rocket. will post photos much much later for everyone to see whats going on here :D haha.

Good job everyone. I'm happy that i noticed in git that by accident.
[G4 General] dianxxyyzz:
Will upload in half a hour new version that include the new kernel with full f2fs support . :)
[G4 General] dianxxyyzz:

[G4 General] kessaras:
h815 , Slim 6 rom , Llama kernel , f2fs combo.

Here it is. With f2fs!
[G4 General] steadfasterX:
Great so you included the llama kernel?

Maybe a changelog in the OP would be nice to have.. ;)

Btw: as a feature request I would like to see OTA support :cool:

Hmmm,I would like to try this rom but I'm using Dual Boot Patcher to try roms on the second slot,I wanna keep my stock intact.

But then I can't format data&cache to f2fs with Twrp because it will be applied to stock rom,right?

Is there some way to do it? :confused:
[G4 General] dianxxyyzz:
It is not mandatory to format f2fs . :) you can install it like any other twrp room too :0
[G4 General] kessaras:
This phone never stops to surprise me. Read write gave me 210mB around, more than galaxy s7.. I beat them all new phones, but after 5 minutes of stress test I lost 45% battery and then I got a kernel panic at the same time. So I didn't get screenshot and I'm out for coffee.... Will run new test tomorrow lol

And post screenshot
[G4 General] kessaras:
yeah the whole partition will be formatted so it will be applied to your other rom too. better avoid it unless you are sure both roms work on f2fs and you have full backup. formatting to f2fs deletes everything including internal sd.
[G4 General] kessaras:
this is my read write speed on f2fs + slim + llama

our ram random read write is also very fast but i focus now to our read write speed on f2fs. its too fast....

Its our internal sd here, not the external, its just that this is the first app i found in front of me and i used it without knowing if its good enough.

ill bench it on antutu too to see an overall of everything.
[G4 General] papsr6:
Which partitions we formatting to f2fs?

Only data or data+cache+dalvik?

Is this rom better than the others on mm?
[G4 General] kessaras:
there isn't any rom better than the other. they are just different.

f2fs only data + cache.

this is the only rom currently fully supporting f2fs. to go f2fs you must format your partitions to f2fs, then you won't be able to use other roms, unless you format back to ext4.

yes f2fs is better and faster, but if you are totally amateur , better stay ext4.

try this rom on ext4 first to see if you like it or not.
[G4 General] raptorddd:
would you build one h811. i want to try it. not sure if you need another thread..

its been a while since i used CM or AOSP. for best camear settings and features if i want same feature as stock rom.? wich should i use.. i want to give slim a try.. just for the battery.
[G4 General] dianxxyyzz:
Yes ,I will build today the version for h811 too
[G4 General] kessaras:
i'm very satisfied with slim + llama + f2fs. i'll stay like this from now on.

will be nice if someone ever feels like to take upon the official maintain of slim for our g4.
[G4 General] raptorddd:
using F2FS do you get shorter battery life.?
[G4 General] kessaras:
shorter battery life ? No....

Trully, it's all fine, or i would have changed it already. I'm on f2fs from now on.

F2fs only downside , is that 1st time something open up, it fully caches before it can run at maximum speed. F2fs caches everything. That isn't bad by my point of view since /cache partition it's only for that reason. Second time we are going to run the same thing, it will run at thunderbolt speed.
