Re: Calkulin's E4GT v1.5a [Rev 5 l Fast l Tweaked l Battery Saver Script]
Tried to reply to the thread in Dev section but said I didn't have permission. But I wanted to get this out there:
This is the best ROM I've tried on the GSIIE4GT yet. Battery life is phenomenal.
I'm 1,200 miles from home visiting my very sick mother in the hospital. After a fresh charge, I was able to keep my family updated about her status via email and text. The battery lasted 13+ hours with a display time of over 5 hours. Call time was around 90 minutes too. Today is more of the same. Display has been on nearly 2hours straight and I have 76% battery left.
Thanks for an awesome ROM!

As far as battery life, you are 100% correct when compared to all other custom ROMS I've tried.
However, 3 things bugging me about the current Calkulin ROM:
1. Can't run Polaris Office
2. Can't install any ICS theme
3. Every time you upgrade a Calkulin ROM you lose all your installed apps and data.
I tried only wiping cache, davlik before a Calkulin update and phone wouldn't even boot
which forced me to do an ODIN reinstall before I could even regain CWM 5
which allowed me to do a complete restore from backup.
For anyone who wants a very good custom ROM without those 3 exceptions,
I suggest Phantomhacker's Starburst 1.9.8r

1. True
2. Actually there is a great ICS theme made by Overstew (search for it at theme section) and its pretty cool.
3. It is possible to upgrade Calk's ROMS just wiping cache and dalvik, but changing from another ROM you have to format all. (At least I havent encountered a problem doing it this way, been using it from version 1, would recommend not restoring anything from titanium the first time you change to Calk's Rom).
Calk's ROM is very fast and stable, Starburst its also very fast and stable... We are lucky to have great devs working on our phones.

Sometimes true. It's different for everyone. Some people have to do a full wipe (like me) and others don't. TB makes re-setup rather painless anyways. My phone was back to its previous state in about 15 mins after wiping and flashing 1.5 over 1.1.

Thanks guys. Appears Overstew posted an update that does work with Calkulin's 1.5a which i just installed after wiping cache & davlik 3x each. As far as what happened when I tried to upgrade from Calkulin 1.0 to 1.5 I tried to do it with the same wipes plus format SD and could not reboot past initial boot screen, which is when I had to ODIN a ROM & CWM5 to fix things.

1. Yes, Polaris Office does work, I just installed it to check. Here is the apk if you need it -->> http://db.tt/113UwR7Z
Update: I take that back, I know what you mean. You try to open a document, and the screen just flashes black, and goes back to the file explorer.
2. As someone else mentions, the theme has been updated to work with the latest version of Calkulin's.
3. You should use titanium backup to backup all your apps + data. And use Go SMS Pro to backup all ur text messages. I been doing this since I had the OG Evo, and I have not lost my apps and/or data even once.

Some folks say you don't have to wipe anything to jump from 1.1 to 1.5a. Some say wipe cache. Does it just depend on the luck of the user, or was there an OP somewhere for the migration from 1.1 to 1.5a.

I decided yesterday that I'm going to give this rom a shot as my first flash on an Android. I've seen that the "bare" is the same as the full version, minus some bloatware apps. However, I can't find anywhere what apps are missing from the "bare" version. Can anybody tell me what kinds of apps are removed? I don't need a full list, just an idea of what is missing.

Calkulin's 2.5.1 Battery saver script script with Tegrak

[Q] I'm Novice and need some help with BeastMOD 4.0

Hello Everyone,
I'm novice and received my SGSII last week. I was able to rooted with odin method. After reading review on this forum, i want to update my ROM to BeastMod 4.0 and kernel to Faux .006 but bit worried about the method.
Can someone who has above combination flash on their T-mobile SGSII phone can help me to correct steps.
My main concerns are:
1. When i flash BeastMod 4.0 ROM will it also flash synergy kernel? If yes, then how can i reflash only kernel because i want to use Faux .006 kernel.
2. If i do step#1, hoping it will wipe out all the default T-mobile factory apps, what is the best way to save all the apps and needed informations.
It might sound stupid questions but I wanted to be on safer side and dont want to crew my phone.
Thanks in advance.

Use titanium backup to backup apps+data. You can YouTube a tutorial or read around the forums here for a guide. Then boot into cwm and do a nandroid backup. Then you're ready to flash.
1. Wipe data, cache
2. Flash the ROM
3. Flash the kernel you want
4. Wipe dalvik cache, fix permissions
5. Reboot, let it sit for 10 mins
6. Reboot.
7. restore data+apps from titanium
There are better guides out there, this is more of a quick overview.

I always do the boot routine before flashing a new kernel. I think I remember reading that somewhere and ive done it ever since. Also when wiping in clockwork mod I like to format system to ensure a 100% clean flash. You could private message me if you have any questions!

I would recommend becoming very familiar with booting into cwm by the 3 button combo. This could be really important not bashing rom manager but I used to use it and when running into problems with my vibrant I found the. Button combo to boot recovery was a much better way and u also control everything u do that way ... just a heads up

I take a slightly "cleaner" approach to wiping, but similar. One thing that's missing is the "system" partition from your steps. Which is under the "Mounts and Storage" option.
I recommend wiping the "/system", "/cache" and "/data" partitions in there. (I always do each twice, to ensure full wipage)

Not really a true "backup", but it'll work.
Just hit "backup" and it'll tell you where it's going.

Before you wipe everything you use titanium to backup all your apps and data. it stores it all on your internal storage (by default I believe). After you flash the ROM, you use titanium which will auto detect the backup and allow you to restore everything.
Edit: the wipe doesn't delete the internal storage. At least when I wipe it doesn't. I'm still a noob at this stuff too

Correct.
Just be sure to backup and it doesn't matter if you screw something up or not (and by backup I mean a backup in CWM as well as Titanium) I don't even bother with Titanium.

Why is this happening to my Gnexus?

Hey fellow gnex community! I recently left stock rom due to freezes and random reboots. I've tried out various rom and kernel combinations this week such as xylon/AK, Purity/AK, AOKP/franco/lean, CM10.1/trinity/franco, Rasbean/trinity, PA/lean/franco/trinity/AK and Xenon.
The problem is they all freeze and reboot constantly after 2 minutes of use. I never changed the kernel settings and this is only happening on 4.2.1 roms. My favorite rom/kernel combo would be purity/AK, Xylon/AK but they freeze, wifi disconnects and never connects back and reboots constantly.
So the question is why is this happening to my phone recently and are there specific kernel settings that will stabilize the roms or is it just my phone?
Any help would be great,
thanks.

I haven't had that problem before, and I have flashed several roms (though not a custom kernel in a while)
Faulty hardware perhaps?

I've done that twice already and usually wipe after it freezes but then still happens

Are you sure you know how to flash? Not trying to offend but it saves a lot of time if your a noob.
I currently wipe dalvik cache 3x, cache 3x, and factory reset 3x in twrp. I read somewhere its safer to wipe like this or use super wipe scripts or w.e
I am running the latest rasbeanjelly with latest rasbean gapps and latest lean kernel. I haven't had any resets and haven't tweak anything. May I also add that when I do get errors with roms normally when I flash extra mods I always go back to recovery and hit fix permissions. Idk why but it does solve some issues.
Good luck
Sent from a slice of Galaxy Nexus with some Rasbean Jelly!

lol. Ya I've been flashing roms for like a year and it's only recently these issues are popping up. I do pretty much what everyone does - wipe data, wipe cache, wipe dalvik, flash rom, flash gapps and flash kernel. I never use mods so nothing to worry about there.

Try flashing rom and gapps only without a custom kernel.
If you've fully formatted your drive, have updated recovery, and are positive you have good downloads then your problem is most likely hardware related

Try the kernel cleaner script before flashing/changing between kernels.
It's a cwm flashable .zip.

Alright will do as suggested

How about fastboot flashing the stock rom's .img-es? (Galaxy Nexus ToolKit is the easiest way to do it)

Alright so it seems like the rom HumberOS with built in kernel did the job. Been using the phone for about 4 hours non stop and no freezes or reboots so far. Finally something stable for my phone! Thanks for the help everyone!

update: After a day without any hiccups on the humber os rom, my phone finally froze and rebooted. Since I was using cwm, I decided to see if twrp would solve the problem. I restored my phone to stock and started from scratch by installing twrp. Then I decided to give PA a try and to my surprise no reboots or freezes at all but will have to wait a day to confirm.

You did restore the factory images by running the update script included in the package right? This will make sure all data is up to date.. Fastboot erase all partitions first as well..

yup did all that and everything seems to be going fine so far

So... what would be causing the problem you think?
You installed TWRP and PA both at the same as I can read in the previous posts?
So that way we will never know if it's a recovery problem, or ROM problem...
Well, as long as your device doesn't freeze and/or reboot we should be happy I guess.

[Q] reccomend me a rom.

I am currently using the MOAR rom by NOOBZ, and love it except my phone reboots about 30 times a day.
when they updated the rom i flashed the new one and still have the same problem and reading the thread so do other people.
I want a rom that has good loud audio, i've read features on a lot of roms and couldn't find any except the noobz rom that had extreme volume
listed. 1 with beats installed would be cool also.
but i've got to get a new rom it reboots in calls and at bad times.

Most likely you did something incorrect. I would wipe phone completely clean and reflash the rom.
Transmitted with a portable device using Xparent Blue Tapatalk 2

Do a complete wipe before install. If you are using another custom kernel make sure, it is not a cause for reboots.
Sent from my SPH-L710 using Tapatalk 2

There is a flashable zip that will enable extra loud volume in any TW rom

MOAR is my goto rom and runs better than stock, how did you install it and with which options? If I had to guess in the dark, I'd guess your kernel voltages are too low but who knows...
If you want something different maybe try TPR or venum?

Not enough info to assist you, what kernel did you flash? What audio mods have you flashed? Sounds to me like you want audio so I am curious what type of mods you have flashed following the rom and what kernel settings you have.
I suggest you boot into recovery, wipe dalvik, cache, factory/data and the flash the stock or optimized stock kernel and whatever mods via the aroma installer. And DO NOT flash or install anything else for a day or two.
Phones rebooting are 99.99% kernel related, the other .01% is bad phone or just plain bad karma related.
Hope this helps, let us know.

Try a fresh download to your pc, then transfer that to your sd card. Could also be a bad download
I cannot hold on,
I will not let go

i fallowed all instructions on the rom page for install, and stock kernel and extreme volume.
i have reinstalled the rom 3 times and 1 of those was the latest updated version.
it's a problem listed in the lond thread on the rom, but low post count can't post there yet.

its probably Bad kernel install or bad download. Naddict is more than likely correct. This I have to say, I don't recall seeing anyone reporting multiple boot loops running moar. This rom is one of three of the most stable and well put together roms I have run. Good luck

[Q] Horrible battery life.

I feel as if I'm the only one with horrible battery life. On average my battery lasts around 8 hours and that's if I check up on it once in a while. I was at 41% charge and I watched a 4 minute youtube video and my battery dropped to 33%. My phone was rooted but that was it, I don't have any knowledge on roms or anything. Can anyone else recommend what to do with my phone? I don't want to sacrifice usability but I really need a longer lasting battery. Are there any ROMS I can download, or kernels, basically anything to help out.

Try out the infamous 2.0 kernel, can grab it from the infamous rom i believe.
its known to give really good battery life. also kts kernel with good set up can also give good battey life.
can also download betterbatterystats and see what is draining your app. try disabling sync and look at how many accounts are synching...all those are factors in battery drains.

Before you flash ANYTHING you should ALWAYS do a nandroid backup. This backs up what your currently running and if you get in a pinch you can always restore your nandroi d backup. Never install anything without doing your backup first. You will be very glad you have that backup at times. To flash a rom or kernel you must first be rooted. Then your steps are first do your nandroid backup then go into recovery by pressing volume up power and home button. This will take you to your custom recovery that you installed after rooting. Then you wipe data factory reset then wipe cash and dalvik now you won't have a system and you can cleanly install your rom. You will choose zip from sd card.scroll through and find the rom you placed on the root of your sd card. Now install then reboot. That's it. If there is any issue with the rom you can restore your backup the same way but you would wipe then press restore backup and choose the backup you wish to restore. Hope this helps. But read read and read again. Do not make any changes to your device until your comfortable and have read and understood the processes thoroughly!!!

Thank you so much! I've successfully installed the infamous Rom and it looks cool so far, the question that I have is can I have a rom installed and can I download Kernels from other Roms. I'm still trying to maximize my battery life .

Yes you can download and install other Kernels as long as they are compatible with your rom. For example, if you have the Infamous Rom installed which is TW (TouchWiz) based as opposed to AOSP/CM based, you can install compatible TW kernels. I'd recommend looking into the KT-SGS4 Kernel at http://forum.xda-developers.com/showthread.php?t=2393708.

Its true. It will help. But keep in mind you have to sacrifice some features to achieve it. Its a great solution for some, a horrible solution for others.

I installed Infamous rom yesterday and in total i got 6 hours and 30 minutes of screen time... this was a huge improvement, i was using it heavily the entire time, i was watching video after video... I dont know if its the best rom out there but it works for me.
Edit- Just installed the KTS kernel, hopefully this will further extend my battery life.

6:30 of screen on time is pushing the upper limit of what you can expect to see. So it sounds like you have fixed your issue as well as you can.
