Hi,

I think I bricked something here. Can someone give me a little help? =D

I was running some 5.1 rom. Copied chroma and gapps (from first post) to my internal storage, rebooted to twrp, did a factory reset, wiped /system, installed chroma.zip (it was really fast, oddly fast), installed gapps, rebooted.

... and got stuck at that black boot screen with an open lock and the name "google".

Tried factory reset + /system wipe once more, then installed chroma and gapps at the same "batch install", but the same happened. Also tried installing and not installing the superSU (twrp asks for it when rebooting).

How can I correctly install chroma?

Thanks in advance =]
[Nexus 4 Android Development] fireillusion:
Maybe it's a bad download of the rom zip. Did you try downloading the files again?
[Nexus 4 Android Development] yochananmarqos:
Sounds like the ROM ZIP is corrupted. Download it again & check the MD5.
[Nexus 4 Android Development] lampsBR:
I'll re-download and try again. As soon as I get the results I'll post'em here. Thanks!

edit: Unfortunatelly both md5 are matching, so I don't think it was just an error copying to the phone. Anyway I'm trying again

edit 2: file inside android fs has only 150 MB. Trying again with correct file. lol

thanksssss dude!

edit 3: Working perfectly. The first file was corrupted while transfering to the phone. Thanks dude! This is probably the easiest to install rom i've used. =D
[Nexus 4 Android Development] fireillusion:
Good morning and merry Christmas to everyone.

I have a question:

When installing gapps am I supposed to see all basic Google apps installed on first boot, like gmail, Google+ etc?

I installed the rom successfully and I am very satisfied with it but had to install all the apps manually even though I chose to restore my previous configuration.
[Nexus 4 Android Development] Benjamin_L:
Yep, most 6 gapps come without additional apps which i love because i dont use them
[Nexus 4 Android Development] sam 4x:
Urgent help Please !

I was playing around with layers on the 6.0 build and to be safe had made a full nandroid backup. Now that i restored it, the restoration is successful but im getting a bootloop. It wouldnt go past the chroma logo. Sitting there for a while now. What should i do ? Dont want to start from scratch. Please help !
[Nexus 4 Android Development] burningwipf:
Did you try flashing the rom and restoring only the data-partition from your backup?
[Nexus 4 Android Development] sam 4x:
No i didnot. Had no clue as what to do ?

So, are you suggesting that i wipe everything and then flash the rom and restore only data-partition ? It will be helpful if you can elaborate please ?

Thank you

Can anyone please help, im without a phone right now !

Can I pull the kernel that comes wit the rom from the zip? I installed Quanta kernel but after a few hours of use the phone lags really bad. Clearing recent apps helps for 30 minutes or so but in most cases I have to reboot. I'd like to return to the kernel from this rom. I know I can just reflash the zip but I'm just curious if I can just pull the kernel from the rom zip and flash via fastboot.

Edit: I just flashed boot.img from the zip. That's all to it right? (Sorry been out of the loop and getting rusty :| )

Thank you. I'll try this out as all the other options aren't working.
[Nexus 4 Android Development] yochananmarqos:
Yes, you can extract the boot.img from the ROM ZIP and flash it. However, I recommend dirty flashing Chroma instead as Quanta modifies the ramdisk.
[Nexus 4 Android Development] fone_fanatic:
Isn't the ramdisk included in boot.img? I'll reflash if it starts acting up. It's running smooth as new currently.
[Nexus 4 Android Development] yochananmarqos:
Quanta V10 was rebased on AOSP, so you might be fine. When it was based on franco.Kernel, I had issues without dirty flashing.
[Nexus 4 Android Development] Bazim:
I have still big problem with notifications. Facebook messenger is delayer or nothing at all and my alarm clock too doesnt auto run in setted time. Like today i set alarm to 8.30 AM ... I wake up in 8:25 AM and i wait for it. In 8:35 AM still alarm doesnt run. So in 8:40 i unlock the phone and alarm started facebook messenger get a meswsages etc. My phone very badly taking notifications when its locked. Please help me.
[Nexus 4 Android Development] burningwipf:
Yeah you could either wipe everything and try restoring the backup again or you wipe everything, restore only data from your backup and flash rom and gapps new.

Not sure if it works but i guess it can't do any harm to try
[Nexus 4 Android Development] biondi53:
I'm on cm13 and I have the same issue, sounds like play services issue....
[Nexus 4 Android Development] dcop7:
The boot.img does have the ramdisk modification. So, if you flash boot.img, you don't have to dirty flash anything.

Just to explain a little more...

The boot.img contains the kernel (including ramdisk modifications, if it has modifications). The most important question is "why do we need to dirty flash the ROM before flashing a new kernel?"

The process of dirty flash the rom is just to flash the ROM's default kernel. You can skip the dirty flash the ROM if you extract the boot.img and flash it with ADB or create a new ZIP (but it is more easy just to dirty flash the ROM).

So, why do we need to flash the ROM's default kernel before flashing a kernel?

You will only need to flash the ROM's default kernel before flashing a kernel if the kernel you are flashing was the AnyKernel script to install the kernel. The AnyKernel uses the ramdisk that came with the ROM, so that is why you need to flash the ROM's default kernel.

You can check the thread here:

It appears that the AnyKernel2 doesn't need the ROM's default kernel, but the DEVs of the kernel you want to flash need to update the installation script to AnyKernel2. But just to be safe, flash the boot.img :)
[Nexus 4 Android Development] fone_fanatic:
Thanks for that info! Learned something new :).

I had quantas kernel flashed and didn't like it (really laggy no matter what governor out scheduler I tried) and wanted to come back to the one with from this rom. I flashed boot.img from the zip via fastboot and now the rom is back to being buttery smooth!
[Nexus 4 Android Development] sam 4x:
Thank you for responding. When you say wipe everything does that include internal storage too or just the 'Swipe to Wipe' which is the default option in TWRP recovery?

Sorry about so many questions but iv lost track of many things. :angel:
[Nexus 4 Android Development] fr3quency:
Advanced wipe > wipe /system, /data, /cache & dalvik-cache. Internal storage doesn't play a key role in the whole thing. if you wipe internal you will lose everything. The things that matter when flashing a ROM are /system, /data and /cache.
[Nexus 4 Android Development] sam 4x:
Thanks mate! This is a life saver.:)
[Nexus 4 Android Development] cry0this:
This option is in Settings -> Display
[Nexus 4 Android Development] zaclimon:
Quanta is still "based" on Franco kernel. I Just have left the kernel version on 3.4 instead of upgrading because it was causing the mentioned issues.

Though it is better to flash the boot.img directly from chroma without flashing the whole rom.

[Nexus 4 Android Development] oliver7:
Just wanna say: quanta v10 is running awesome :good: on my chroma, i only use custom gamma, speaker vol., and d2w, but it's all still buttery smooth unlike other kernels i tried.
[Nexus 4 Android Development] sam 4x:
I did try both ways but none worked.

In scenario 1: Wipe everything and restore, it was just stuck on Chroma splash screen for a very long time.

In scenario 2: Wipe everything, restore data and flash ROM and gapps, it booted to optimizing apps and then 'error message- process.phone.android has stopped working' and then boot loop.

I tried a 3rd scenario where I flashed the ROM and restored only the data but same behavior as scenario 2.

I even did a clean install and tried to restore data using Nandroid Manager but just ended up in errors.

I'm really confused and sceptical after this incident that whether I should be relying on Nandroid backup anymore.

Unfortunately, I had to do a Clean install and start fresh.

Thanks for you suggestion, though !

Why in the last build is not used the hellscore kernel?
[Nexus 4 Android Development] WarioNeila86:
Great ROM for a great phone! Thanks for your work.
[Nexus 4 Android Development] 320flyboy320:
Just wanted to say thanks for the great work on this ROM, I'm really enjoying it :)

I do have one problem, and I apologize if this has been answered before, but after searching for some time I can't find a solution. When I try to open Gmail, it opens for a split second, and then closes saying Unfortunately Gmail has stopped. I can't seem to update it with the play store and I have downloaded the apk from APKMirror and tried to install that, but it says installation failed.

I did as instructed by the OP for flashing, and used the Gapps posted on the first thread.

Anyone have any ideas?

EDIT... I was missing one important step...forgot to wipe "system" in advanced in TWRP. All is good now ;)
[Nexus 4 Android Development] caesium2:
Anyone else having problems with bluetooth headsets? I got two headsets. I can pair both for one time, but when I switch off bluetooth and enable it again, it does not reconnect.

I am on Chroma with standard kernel.

Anyone got an idea what I could do to troubleshoot? Logcat just says "failed to connect A2DP device".

EDIT: After a clean flash (chroma + recommended gapps) it does not work either.
[Nexus 4 Android Development] smaaz:
I am loving this rom for its above average battery life, but this ROM is so minimal, please someone tell me how can I get stock email, music, clock even SMS all of these features are missing.
[Nexus 4 Android Development] caesium2:
Just install the apps you want from playstore.
[Nexus 4 Android Development] fireillusion:
is doze implemented in this rom? and if it is, does it work as described by google?
[Nexus 4 Android Development] Spiralzz:
Doze is an Android (OS) feature, and is implemented in ALL Marshmallow ROMs, so yes.

Does it work? Yes.

Hi

I saw in a post on G+ that in this ROM the navbar problem is fixed, could someone confirm that please ?

NavBar Problem: Unresponsive nav buttons. (I already tried NavFix on Github but worked for a few hours, Do i need to replace the Digitizer ? )
[Nexus 4 Android Development] caesium2:
I have no idea what you are talking about. I never had any problems with the navbar.
[Nexus 4 Android Development] speedypoint:
It's a hardware issue and cannot be fixed via software.

A temporary solution is to use the command wmoverscan 0,0,0,10 in terminal.

Try to increase the the last value in increments of 5 till you have removed the unresponsive section.
[Nexus 4 Android Development] ashjas:
Syslog does not work on this ROM for some reason... Nofiles exception it gives... No logcat etc... Anybody too?

Could you link the thread for the fix, can't use my keyboard so please bare with me. Wmoverscan command returns nothing 4 me.

I guess you mean increase. 10 by 5 increments until job is good. Having to switch between landscape & portrait just to write this.

It's OK I have discovered how to do it now , thanks j

Has anyone gotten WIFI tethering to work on the 6.0.1_r3 version? A WIFI AP gets created and I can connect to it however, no traffic is passing thru it. Checked the build.prop in /system and it has the noprovisioning=true bit set. anything I'm missing here??

Well, I think that this issue appears at almost every page in this forum. If you will take a look back at some pages or search, you will find that turning WiFi scan off will fix it.

Is it me or is there no significant news of further developments in chroma! can anyone tell me what is going on?

Good grief! Read the last few pages. Posts like these discourage development.
[Nexus 4 Android Development] dragos281993:
The dev may be enjoying some drinks under the lovely burning sun of Hawaii apart from all this development that can get pretty tense and exhausting sometimes. In other words, he's probably taking some time off. There aren't any major bugs in his ROM so the latest build is stable enough for everyday use, for every device that he's currently maintaining.

(* the bugs reported are due to moving between kennels without following the necessary steps, no necessary wipes before and after an important procedure, etc)
[Nexus 4 Android Development] Sonoo:
Dude the previous pages had nav bar issues, wiping issues etc. Thats why i asked. Sorry if i offended u
[Nexus 4 Android Development] yochananmarqos:
"Dude", you didn't read back far enough then. It helps if you find out who the dev is and finding his last post. Common sense.
[Nexus 4 Android Development] dragos281993:
The "navbar issue" is not ROM related. You'd know if you actually wasted some of your precious time for some actual reading. And there's no wiping problems. 75% of the people that complain on every thread either don't even read the comments on the same page for answers, or don't do the necessary wipes when needed, they flash kernels over other kernels, etc, then start complaining about bugs. The search function in each thread is resting and waiting for people to start using it.
[Nexus 4 Android Development] GIL0802:
Thanks for the help. I temporary fixed with GravityBox increasing the height of the navbar. It's working now but i know i have to replace the digitizer.

Thanks anyway! :D

Hi people!

I'm in the latest Lollipop version of Chroma. Two days ago I started to have a strange battery drain, and with BetterBatteryStats I think it's the android.process.media process (it's the first in the list).

I didn't do anything nor put new media in the mobile. I provide the info you'll need as soon as you ask and I can.

Could you help me, please? Thank you so much :)

Hi guys, I am using this rom with LMT launcher and there is sighnificant lag when I use LMT`s back and home buttons,any idea what may have caused it?

Solved.
[Nexus 4 Android Development] bigb1234:
You should consider upgrading to Chroma Marshmallow... with a combination of doze, greenify, custom kernel, underclocking and undervolting you can get greater battery life...i have a faulty battery but still i squeeze full 24 hr battery life using the above...

P.S.- Greenify has exclusive feature for Marshmallow which helps in taking doze to the next level.
[Nexus 4 Android Development] arjundas86:
I've been using Chroma (Dec 7th - currently latest build) as my daily driver for just over a week now. Finding it quite stable, fast most of the time (a few lags here and there), and has most of the features I want (coming from CM12.1). Battery life has been decent too - without Amplify and PowerNap on Chroma, I get about the same as what I used to get on CM12.1 while using those - Biggest factor seems to be Marshmallow's doze.

One thing that has been bugging me is that the phone sometimes charges slowly from chargers where it used to charge quickly before. On the lock screen it displays the "Charging Slowly" message, and it charges about 5-10% per hour. At work, I'm using the same charger and cable that I was using while on CM without this issue (it would charge ~30% per hour easily), so I don't see how it could be a charger or cable issue. Plus it seems intermittent - yesterday it charged fine, but today it's slow. Any ideas?

---------- Post added at 11:19 AM ---------- Previous post was at 11:11 AM ----------

Can you elaborate on this please? I use Greenify (yes root, no xposed, no donation package)... but haven't seen any difference from back in Lollipop.

I'm also using the latest lollipop version of chroma. Having this wired bug that after some time I am not able to play any video on my phone. YouTube or any other app that plays videos is affected. Only solution is to reboot...
[Nexus 4 Android Development] ubston:
I'm having trouble getting this rom to function without GAPPS. Perhaps it's not meant to. Has anyone had success?

With the latest Lollipop, the home button doesn't work. With the latest MM, it won't properly mount on my computer (internal storage doesn't show up), and so I can't install F-Droid.
[Nexus 4 Android Development] dragos281993:
Wow, I don't mean to be rude but I see some complains that are not funny anymore. In M, the storage appears on you computer only if you open the notification panel on your phone, tap on "USB for charging" that appears as a notification right after you plugged in the phone, and select "File transfers".

And the ROM should work with or without Gapps. Just make sure you do the necessary wipes before flashing the ROM.
[Nexus 4 Android Development] ariesgodofwar:
It seems some times to have issues properly distinguishing whether the source is USB (in which case you see charging slowly and the phone draws 90-130mA) or AC Charging (in which case the phone pulls the proper 500+mA). It seems reconnecting usually solves this, but the behavior does seem a bit strange.
[Nexus 4 Android Development] ubston:
You're not being rude at all. Thanks for your answer, and apologies for not figuring that out on my own. I hadn't used MM before. However, I should note that I wasn't complaining - I was just asking a question.
[Nexus 4 Android Development] arjundas86:
I tried reconnecting several times, but didn't help.

Definitely strange that yesterday the same charger and cable worked fine and today it's charging slowly. I suppose it's possible, however unlikely, that the cable crossed a threshold in degradation between then and now, but I think it's more likely something in software. I'll wait a couple more days and see if it flips back to normal charging again. If not, I'll try getting another cable.
[Nexus 4 Android Development] purgy:
try turning off wake on charge in settings > display, that fixed the AC being detected as USB issue for me.
[Nexus 4 Android Development] fireillusion:
Concerning the WiFi battery drain I can confirm that sometimes when I press the icon on quick settings although it disconnects the icon doesn't appear crossed out and in battery settings it is displayed as active (green bar). I have disabled WiFi scanning always active setting.
[Nexus 4 Android Development] fone_fanatic:
For those of you having WiFi constantly on and draining even when you toggle it to off, keep wifi on set to never, and wifi scanning off, try updating SuperSU: http://download.chainfire.eu/896/SuperSU/BETA-SuperSU-v2.66-20160103015024.zip

It fixed it for me for a day, but I just checked now and although I had WiFi off for the past 4 hours it's still reporting WiFi was on in the battery graph :/ BUT my drain isn't as bad as before so I'm thinking the battery graph is misreporting that wifi is on when it actually isn't...

---------- Post added at 07:11 PM ---------- Previous post was at 07:06 PM ----------

Just read through the replies/posts and I'm going to agree with several of them that the battery graph isn't reporting properly. After I updated SuperSU my phone isn't draining as fast but still showing WiFi is on in the battery graph although I don't think it is. I'm going to try what several have posted as a fix which is to set WiFi frequency to 2.4 only and disable scanning.
[Nexus 4 Android Development] ubston:
After reflashing, I see that USB for charging option. But I swear it wasn't there before.

Can anyone tell me if Privacy Guard is included in the MM version of Chroma? I can't find it anywhere. It used to be under Settings > Security. But now it's not. From what I can tell, it's included in CM 13. So I don't get why it's not in Chroma!

EDIT: Oh, I guess the Privacy Guard features are now in Settings > Apps > Configure Apps > App Permissions.

EDIT again: I don't think app permissions and privacy guard are the same thing. So, this version of chroma doesn't seem to come with privacy guard!
[Nexus 4 Android Development] arjundas86:
I have always had it off.
[Nexus 4 Android Development] ashjas:
Do you use usb fast charging option available in some kernels? like taurus kernel?

For me, this option does work, the lockscreen shows "Charging" fine even on USB connection after enabling this setting.

But after a USB disconnect, it shows "Charging Slowly".. even when the fast charge setting remains.

This gets to show "Charging" again only on a reboot.
[Nexus 4 Android Development] TNSMANI:
I am also facing the USB/slow charging issue. I also noticed a particular Wakelock being triggered for the whole time the slow charging was on. Unfortunately I forgot its name. The slow charging is totally unpredictable and happens sometimes and doesn't happen at other times. The only sure way to switch it to normal/fast charging is to reboot the phone after connecting the charger. All other methods of switching are only hit or miss.

For me normal charging from 10% to 100% takes about 3+ hrs whereas under slow charging it takes 6+ hrs.

EDIT:

When I connect the charger, usually the batterystats page shows 'charging on AC' but in about 5 to 7 seconds, it changes to 'charging on USB' and then it sticks to that. If it doesn't change to 'charging on USB' within that time, charging continues on AC mode without any issues.
