Root Time for a change of ROM?!?

I have encountered the "black screen bug" where the screen stays lit. In my case it is intermittent. Most of the time, the screen turns off properly, but once in awhile I had a lit black screen. Since the problem is intermittent, looking for a fix is difficult. I understand this will be fixed in RC8.

It could be a problem in daytime when I won't be able to tell if the display is actually off and will probably have to restore another ROM.

Some questions. The file system of JB is a bit different from ICS. I cannot seem to find the vdd_level file which displays the voltages assigned per clock speed.

Also what happened to /system/etc/init.d/01sysctl?

From the 01sysctl file I could edit voltages, available frequencies, governors and other settings.

Oh, by the way, there is a workaround for the camcorder. Open camera, switch to camcorder, click home quickly, switch back to camera and it will now be on camcorder mode.
 
Made a mistake about the workaround for the camcorder. I can get it up and running, but when I take a video ay 720p 80% of the display is covered in static. I can shoot video at 480p.

I too got the black screen...

Kernel 8 Test 3 seems to fix this problem.
 
Since this has become the "we are all on Jelly Bean except for the OP = JelyTime FAQ" thread... (yes, back on his case again, but he started this thread, and look at the mess it got me into)...

Can anyone tell me what the tan and green line in the "Mobile network signal" means:

Seriously, should some start a JellyTime thread. Basically, the thread has been hijacked. Would rather stay here though if ok with the OP (who shall continue not be named until he makes the leap to 4.1.1).
 
Flashed R7.2, than flashed test kernel 3, and now R8 is out, while R8.1 is being compiled.

Has not even been twelve hours yet. Now, this is my kind of ROM.
 
scotty85 and D-U-R-X... progress?

Ice Cold Sandwich 8.6.1, AOKP desperately holding on to Sense.

JellyTime R8.0, AOKP as pure AOKP.

Several users have, but I would recommend instead:

Back-up App + Data with Titanium Backup
Back-up System Settings with Titanium Backup (but I don't do this myself)
Back-up your Nova or Apex settings (don't know if this can be done with Trubechet or Launcher)

  • Nandroid backup
  • Wipe & Flash
  • Restore Apps plus data (some apps will have to be activated again, but I just activate Viber and Google Authenticator and the rest on first use)... I don't have many apps and only 1 game though so it may be harder for others.
  • Manually restore system settings (since I don'y back-up)
  • Restore Launcher

= 25-30 minutes

If somewhere along the line you have a bug no one else is reporting, battery life issue or something else is bothering you, than you will wonder if you should not try a clean flash.

If you want to wait for R8.1, I would flash the R8 Test Kernel 3 on the first post on this link.

As near as I can tell:

Test Kernel 3 - Backlight issues fixed
R8 - Also fixes camcorder and adds 6-signal bar
 
OK...rocking JB9!!!







Only just installed it...so you are seeing the original screens...now to test it.
 
JellyTime R8. Battery life is not bad, but am not too sold on it.Maybe I expecting too much?

Charged before sleeping, 6 hours 10% battery usage. Seems to be awake a lot when screen is off. Sync is on for Google Tasks, Calendar, Contacts and Tasks. Twitter syncs every 4 hours (I follow 51 people). Running in the background is GTalk and Viber.

57% Voice calls, 27% display (Image).

1 hour 30 minutes voice calls (Image)

1 hours 24 minutes screen time (Image).
 
There's a lot of awake time Vs screen on time there for the first 6 hours where I presume you were sleeping?

One thing I've found with JB ROMs on the One X is battery life is generally much worse compared to Sense ROMs. I wonder if it's the same for JB ROMs everywhere?

Give Betterbatterystats a go and see if there's anything causing wakelocks or any errant processes running that shouldn't be.

Try turning location services off, I've found that makes a massive difference for me.
 
I presume you were sleeping?

Yup. Several short phone calls (5 minutes all together during the day), with one 1:25 minute phone call before the phone died. This is where Sense 2.1/3.0 Power Saver settings become useful.

Will try Betterbatterystats and a third party app to turn off sync and stuff when I hit 30%.

I guess I could turn off location services since I am not using Sense. When I use Sense I update weather every 3 hours... well to keep the widget "relevant" not that I need to know the weather where I am :)

Additional details. 1:25 minute call ate up 33% of the battery. Battery is four months old, official HTC battery.
 
Wait, I think camera.apk is missing. Read this on XDA. Maybe I can extract it and give you the file?

Update: Well, I have to find out were it is store first...
 
For comparison here is a screenie of power consumption on a GNex on Android 4.1.1. Sync is set-up like my own phone but sync to Facebook rather than Twitter, and used a lot as a music player connected to a car stereo via BT.

Now if I could only find the equivalent on /system/etc/init.d/01sysctl and vdd_level in Android 4.1.1, I think I could squeeze out a bit more life from the battery.
 
I've download R9 but so far I've stuck with R3. All seems to work well with this release and battery life seems pretty good. Maybe it's just me but I'll stick with this one for a while. No black screens as reported in previous posts. Wi-fi, camera, camcorder (480p only) work well.
 
Weighed down by withdrawal syndromes, ral runs back to Sense.

Twitter mainly...

Sense 3/3.6 - Peep + Pocket. Share automatically saves to Pocket as it is set to default there.

AOKP - Twitter ---> Share ---> Pocket. No option to set as default, but at least pocket is on top.

Senseless 4.0 - Whatever the new Twitter apps is ---> Share ---> Select More ---> Scroll to Pocker ---> Pocket. No option to set as default.
 
See you all later.

My replacement Galaxy 3 has finally arrived!! so the old DHD is going on Ebay and I'm off into the world of Samsung.

Just reading up about rooting it and I'm off!!
 
One thing I've found with JB ROMs on the One X is battery life is generally much worse compared to Sense ROMs. I wonder if it's the same for JB ROMs everywhere?

The GS3 JB ROM I'm on has terrible battery life, must get about 9 hours with 2 hours screen time max :( And the CM10 ROMs are so buggy I think the DHD has more stable JB ROMs!

Are you on the Exynos or Qualcomm version?

From XDA:

t's not about samsung or sony.
It's about the soc used. In our case exynos.

Samsung doesn't provide proper sources or documentation for their own platform.
And if they do after it's much to late, it's outdated and incompatible.

Compare the qualcom or omap based samsung phones vs. the exynos ones.
All qualcom and omap based samsung phones got jellybean and butter in zero time.
We're still fighting with exynos and the i9100 guys have to wait another months if it will get jellybean at all.
I assume samsung is skipping it and will only do a value pack. There's no single line of code or a leak yet.
It's a shame.

I9100g (omap4, same hardware as i9100) got jellybean pretty instant. opensource hwcomposer, opensource audio, butter, working tvout
I9100: (exynos4, same hardware as i9100g) buggy jellybean, closed source and incompatible audio, no butter, no tvout, bugs which will never be solved.

what do we learn from this?
Don't buy exynos phones.

On another topic.

JellyTime R10 is out. Downloading. Contemplating an install... well I will just put it on my SDCard and see what happens.

I liked R8 more than ICS 8.6.1, but ICS 8.6.1 gave me better battery life. BlackOut gives me better battery life than both. Choices....
