12/6 is running great for me. I was on M12 and it went all haywire after a month. I actually can't get more than a month on any CM based build before it starts breaking down. I can't think of any technical reasons why that would happen.

i maked clean installation with all wipes....i think that the problem is in modem o other telephone software...now i want to come back to 4.3 if i can, but i don't know the correct instruction because samsung block downgrade...
[Galaxy S 4 i9505 Original Android Development] 78Staff:
Unless you had a rom installed at some point that didn't reboot (other than stock), it just may be a hardware issue. I had an S2 that would "black screen of death/reboot" no matter what rom was on it, other than stock TW. It's a fact of life, some phones come off the line with different capabilities due to so many different components, and there are some that just won't work as well as others...

Hello everybody , i need some help please :)

I installed this rom yesterday and the battery is draining so fast... Any kernel to recommend me please ? I lost 1% every minute :(
[Galaxy S 4 i9505 Original Android Development] sancho_panzer:
I had same problem with recent releases. Try Alucard, amazingly good, but don't go with latest R version, previous QS is much better:

HUGE. Before August the default CM kernel was very good but after that... Well you know. I'm getting almost five hours of screen time with Alucard qs now, but beware that I'm also using latest radio for my network and I don't use Gapps.

Edit: my advice is you should keep all the default settings on STweaks but change profile to "battery" or even "extreme battery".

[Galaxy S 4 i9505 Original Android Development] !crazy:
Such issues are usually not kernel related. Always use some 'better' battery stats apps (like better battery stats ☺.) and try to find out which apps /processes are involved in holding wakelocks and main battery drainage.

Secondly, <b>always</b> let new flashed ROM, or even kernel to settle for a few days.

When you flash ROM lot of 'tracking' initialise their databases, on phones or in cloud, and this takes a lot of the resources at the beginning. After few days things come down, and even such services like Google now, or plus do not have to drain a lot.

Regarding kernels, on S4 you can even use performance governor and have a decent battery, because device has nice MPU and kernel drivers and utilizes its C States and C3 quite nicely (read about race to idle in this regard.).

So if you just flashed ROM ad you have said, just relax, and give it chance and leave it for a few days to settle.
[Galaxy S 4 i9505 Original Android Development] Soufiansky:
You said everything , thank you :D

But i already had cm11 on my device and waited for lot of cycles of charge , and i got that drain , this is why i want to change the kernel this time without waiting ... I'm looking to flash the GPE 5.0 but i think it is not stable enough.

I have just a question i've been thinking for a long time : is flashing roms and kernels on a device can damage the hardware ? because i think i flashed my s4 more than 30 times :D
[Galaxy S 4 i9505 Original Android Development] sancho_panzer:

Blue LED keeps blinking when ROM boots and even on the screen that says "Android is upgrading". Anyone know why?
[Galaxy S 4 i9505 Original Android Development] 1weener:
To me it just sounds like you got a bad flash.

Have you tried re-downloading and flashing it again? This ROM is rock solid at this point and a reflash has saved my phone more than once... give it a try?
[Galaxy S 4 i9505 Original Android Development] stephendt0:
I've had some time to test this again on Dalvik. Here is what I have found:

1. Definitely still an issue. Not sure why. May have something to do with the fact that I have multiple routers with the same SSID. Other devices do not have this issue.

2. Weirdly enough, this one is almost fixed. I would say maybe 5-10% of the time this might be an issue. It's not very common and pressing the home button usually gets me out of trouble.

3. This still occurs, but rarely. Usually if I am doing some intensive task like web browsing and switching between apps, then I lock the screen. Then for whatever reason I may have to unlock the device again, and sometimes then it will do this. I don't think I've had to force it to reboot. Creating folders rarely works and actually causes Windows Explorer to lock up.

4. Still an issue. It's fairly inexplainable. Camera has been crashing a lot lately too.

5. Haven't used Panorama mode enough to test this, but I tried a few times and it was OK. A client of mine complained to me about this exact same issue on their CM11 SGS4 though.

6. Still an issue. Very reproducible.

7. Fixed with an app update, I believe.

8. Honestly this one is weird. Works perfect sometimes, is a pain in the ass other times. Usually starts to be a problem after the first copy operating (ie if you do more than one thing, it starts to play up). I use Wi-Fi sync most of the time now which is reliable.

9. Again this one is weird. Wasn't able to reproduce it. May have just been something strange with my charger at the time.

Other than that, the device works quite well and is still fast and snappy. It's not the buggiest I've used and I've put up with it for some time now. The camera issue is becoming highly frustrating for me at the moment as I have to take a lot of photos for work, and I have to reboot between each time it screws up. Switching between auto flash and no flash will often make the camera crash so I have to be careful.

Might update to a newer nightly. Can anyone recommend a nightly that they've used for two weeks at least?
[Galaxy S 4 i9505 Original Android Development] simonbigwave:
Fully agree with all your points. I also always wait for the Rom to settle few days, and find huge battery improvement with BBS, changing WiFi settings+greenify+lux, still on default kernel. I usually don't even need to charge my phone at all thru whole day (But agree everyone's usage+apps is different).
[Galaxy S 4 i9505 Original Android Development] Soufiansky:
You mean i flash again and wait some days for the rom to be stable ?

I usually can get 4H of screen in a full day with 20% left, every day .. You think it will be possible with cm11 and it's stock kernel ?

Because a lot of people complain about battery life in cm11 , it's a disaster :D

Thanks for your help ;)
[Galaxy S 4 i9505 Original Android Development] 1weener:
No, just reflash it. 1% an hour is way more than the ROM needing to settle. It flashed badly I think.

I am currently able to get 6 hours screen time under heavy use, and right now have almost 3 full days with 3 hours screen time during 3 days of light use, although I do track my jogging and use bluetooth audio everyday for almost an hour. I am at 18% and using 12/13/14 stock ROM and kernel with Delvic.

or you are talking about m13, right ?

M13? Are you kidding me? There's no such thing yet.
[Galaxy S 4 i9505 Original Android Development] Heathered:
Drop the M13, go to CM12... :)
[Galaxy S 4 i9505 Original Android Development] stephendt0:
Nah I'm talking about M12. Believe it or not but there are people (like my grandma) who enjoy the features of CM11 but don't even know what a nightly is and certainly don't like to crack flash new roms all the time. Besides I like to test things extensively. Crazy, I know...

I'm highly sceptical of CM12 considering its not official yet and is a brand new OS. If it takes CM about a year to get a stable ROM then I don't expect it to be acceptable for at least 6 months.
[Galaxy S 4 i9505 Original Android Development] foxbatul:
I see. but I ve seen complain about M12. - this one it s sooo old so it's no point to use.

I this situation, taking in balance that m12 it's ooooollld ( so it's uselles to use ) my opinion regarding your granma it's to stick to the STOCK ROM.

have a great day

[Galaxy S 4 i9505 Original Android Development] stephendt0:
It's the latest M-Snapshot build for the i9505. To many people that's the most recent "stable" version and a lot of people will still be flashing it. Not everyone wants to gamble with a nightly ROM, they just want something that works and something that isn't Touchwiz. How you can say that it's no longer relevant is beyond me.

[Galaxy S 4 i9505 Original Android Development] fjuniper:
To say that M12 is old and useless tells us more about you, than about CM. A clean install of M12 today is as useful as a clean install the day it was released. Software does not become useless over time. (I do accept that M12 was not the best M build of course).
[Galaxy S 4 i9505 Original Android Development] Jsilver73:
CM12 running very stable for me, everything works that I need, and battery life is good, performance is excellent, actually it's much more stable than any cm11 base that I was running prior to L ;)
[Galaxy S 4 i9505 Original Android Development] maltinbay:
Which rom do you using?
[Galaxy S 4 i9505 Original Android Development] foxbatul:
again,I'm sorry but I have another opinion.

M12 it's old and with problems. latest nightly are perfect. as all CM11 , to be honest.

on my S4 black, s3, s2 , s1, note, and so on, I did not have any issues ( only very few glitches on 2 or 3 nighlty in more than 2 years .. ) ,.

on s4 I have 4 days battery life and more than 10 days up time..

form me it's the best ROM ever.

every time I follow all steps to install, no dirty flash or other " user mistake". this software is't 10 times better that original stock.

I can prove this with all details from my own device(s) so , please, DONT spam this great forum/site/thread.Thank you again .

[Galaxy S 4 i9505 Original Android Development] Mittaa:
If you use TWRP or other CWM-based recovery ... then this will do CyanDelta ...
[Galaxy S 4 i9505 Original Android Development] simonbigwave:

regarding the battery life, I dont know if it;s related with my phone ( i have black edition ) or it's the same on the octacore version.

On my old s3 I had not such a good batt live even in the same usage manner so maybe there are some improvment in newer model.

on the latest stock ( nk4 I think ) , the power management it;s also very good ( but on CM11 it;s better ) :) taking in balance the old version.

It doesn't have to be lying at all. It is possible that he really gets what he claims. The point is, that is NOT a rule, not a real example of what can be achieved, or what CM really is, and what CM offers /can offer.

His battery life can be a product of multiple factors which happened, and which are all extraordinary.

That can happen if one gets the best battery which can be produced under circumstances, when all relevant factors happen to be best possible, and when other relevant things match.

What is silly is when someone start advertise how great CM is, or an app, or whatever. That kind of battery life you won't achieve by using specific ROM, or an app /tweaks.

So be thankful and satisfied you got best possible battery, processor, hardware, with nice ROM, apps etc.

On the other side, you are maybe not so satisfied with the fact you make a one minute phone call per month. I am not much better in that regard than you ☺ (this is not directed to you sushidog, that should be clear I hope.).

ota with twrp

hey i was just wondering since i made a clean install with the cyanogenmod installer. on my i9505 intl.

right after i installed twrp recovery with odin. and i now have got an update and i was just wondering if i can update just as normal or does it only work if you have CWM installed?

since twrp is not supported i think by CM i might not get an answer to this but please if anyone of you know does it still work to update as normal with TWRP?
[Galaxy S 4 i9505 Original Android Development] Soufiansky:
I recommend you to flash the CWM recovery or philz recovery , then do the update ;)
[Galaxy S 4 i9505 Original Android Development] kewinhdorff:
what could happen if i do it with TWRP? i don't like philz that much. and i want to try something new so i choose TWRP ^^
[Galaxy S 4 i9505 Original Android Development] Soufiansky:
You can try but do a back up ;)
[Galaxy S 4 i9505 Original Android Development] 78Staff:
I've been using it with CM9/10/11 nightlies, for some time. CWM recovery is no longer being updated anyway, thus Philz is probably in for a change soon as well.

You'll be fine with the correct TWRP for your device. Both CM Updater and CyanDelta work great with TWRP.
[Galaxy S 4 i9505 Original Android Development] kewinhdorff:
i read on the onplus forum that if i update with TWRP root will be lost... but i don't see how it will be affected by that. they also mention that as long as i keep the update recovery box unticked i will still have TWRP ond it will not be updated to cwm.
[Galaxy S 4 i9505 Original Android Development] 78Staff:
I've never lost root on an update - Superuser is included/flashed with each nightly.

I use SuperSU which installs a script to preserve root across nightly updates, otherwise it would need to be manually installed over the built-in superuser after each update. If you use the built in superuser then of course you won't need this.

Yes, just leave update recovery unticked under dev options (it's unticked by default, iirc - I've never needed to change it).

EDIT - Actually, they may be referring to a message that occurs in TWRP on *some* devices, where when you reboot into recovery it may say "Root lost - Install SuperSU?" or something similar. It's a bug in some older versions of twrp - root is not actually lost, you just select ignore and continue on as normal. Most recent versions of twrp have corrected this (it's updated pretty regularly).
[Galaxy S 4 i9505 Original Android Development] kewinhdorff:
oh i see. yeah i have seen that very often in CWM when i am going to reboot in CWM. i didn't know it was a bug. thnx for the information! :D

but nothing mayor bad will happen if i update cm when i have twrp right ?

also one more thing i think is important. when i was using my sgs2 on cm nightlies. when i did factory reset inside the phone in the backup and restore settings, the whole os was deleted from the phone. so i had to reflash it. now that i have installed it with cm installer on my sgs4 if i do factory reset in the backup and restore settings, will the same thing happen? or will it be reset to as when i installed it with cm installer? does anyone know?
[Galaxy S 4 i9505 Original Android Development] 78Staff:
doesn't matter what recovery you use, if you do a factory reset then yes, you will lose all your data. Factory reset is just that, reverts the device back to "out of the box" status, essentially.

When you do nightly updates, you don't have to factory reset. You just flash the nightly over the top of your existing nightly - also known as a "dirty flash". Generally you only need to do a fact reset when jumping from nightly to snapshot or vice-versa, or changing roms, etc. For your basic nightly flashes factory reset is not needed.

Just use cm updater to download and flash the nightly update, and you will be fine. It clears cache/dalvik cache for you, but does not factory reset. You typically would need to then re-flash any gapps or system installed apps as well...
[Galaxy S 4 i9505 Original Android Development] kewinhdorff:
does the cm installer install another modem? because when i flashed to stock with a firmware that has another modem when i installed with cm installer after i got another modem. can anyone confirm
