[Galaxy S 4 Q&A, Help & Troubleshooting] recipientsuperior:
Hello everyone! I'm just getting my feet wet in customizing my device, and I'm looking to improve battery life.

Now, my question is: what is the difference between undervolting the CPU and lowering max CPU frequency, in terms of their respective effects on battery life? Should I try doing both or is either one sufficient?

Thanks!

Guys I recently installed wanam lite rom on my s4. The problem I am having is that for the past few days since installed the rom a lot of people have been complaining to me that they were calling me and my phone was off. And I also noticed that my signal strength is very low nowadays. Which was fine before.

Did installing the rom change my modem which is responsible for the signal and reception ? If yes what can I do to solve the issue ?
[Galaxy S 4 Q&A, Help & Troubleshooting] nnikooo:
I can help you a little, i think flashing custom rom changes your modem, you need to flash right modem for your country and your operator. Someone can enlighten you which would be the right modem for you.

Hi,

I have no idea if the ROM changed your modem.

Upgrading GE rom without wiping data

Hello forum!

I've a Galaxy S4 i9505 device where I installed a Google Play Edition 4.3 ROM (v1.3 by CoOoL_BoY).

Everything is great, however I keep receiving the "system upgrade" notification, probably as I'm not running JWR66Y yet.

I know that OTA upgrades will not work, so these are my questions:

1) If I upgrade from coolboy 4.3 rom version 1.3 to latest 1.5, I absolutely need to wipe my user data? Or things may work well just doing the Dalvik Cache and Cache wipes?

2) It is ok to try installing 1.5 without wiping user data and wipe data only later if something does not work as expected?

3) Assuming data wiping is absolutely required, what do you do in order to upgrade to a different rom but retaining everything else: applications, messages, call history, photos, ...?

4) I saw that ClockworkMod recovery has an option to backup to external SD card. If I perform a backup, try to install a new ROM, and want to return back, I'll just need to restore from ClockworkMod and everything will be as before installing the different ROM, including applications, photos, and everything else?

Thanks in advance for your help!
[Galaxy S 4 Q&A, Help & Troubleshooting] kantjer:
1. Normally you don't need to wipe data, only cache and dalvik is needed.

2. yes

3. make a nandroid backup and backup all your user data with Titanium Backup or something similar

4. That's a android backup, if you restore that, you will have your old situation, including all data back. It's a complete system/data image.

EFS partition format is modified with new firmware. so:

- Restore EFS (that is backed up before this change then flash old modem) or

- stick with MG9 modem which can still read the modified EFS.

Unable to use S4 Google Edition internationally

I have an S4 Google Edition and am using it on AT&T. I recently took a trip to Ireland and wasn't going to be there long enough to justify purchasing a SIM from an Ireland carrier, so I figured if I needed to use the phone, I'd just use it with the AT&T SIM (for calls only, I did not need/want any data access so kept Data Roaming off).

The trouble is, the phone was unable to register itself on any of the available Ireland carriers, whereas my spouse's AT&T iPhone simply worked.

Please forgive my inexperience. I'm a complete noob with respect to using my phone internationally. What am I missing? What did I need to do to get the phone to be usable in Ireland?

I have had to take the plunge for now, as I cannot restore that device, and purchase another...

Basically I want the Google Play Edition ROM, has anyone had any problems with it?

My device crashed whilst using it and that's what put it into a bootloop... (I assume)

Is it really worth doing or is there a safer more stable way to remove all the samsung bloat. I much prefer the purer android rom

it remind me of my nexus 7 tablet, and was much more comfortable to use, even if it was only for 10 minutes or so before it crashed :crying:

No matter what method I use I always get these results...

all other versions of odin I tried (v1.83, v1.85, v3.04, v3.06) just fail;

(again all usb ports, original usb lead, kies is disabled, drivers un-installed/re-installed)

And this read out...

flashing pit and rom > Complete(write) operation failed.

flashing only pit > Complete(write) operation failed.

However on Odin3 v3.07

flashing pit and rom > There is no pit partition

flashing only pit > There is no pit partition

and on v3.09

flashing pit and rom > re-partition operation failed.

flashing only pit > re-partition operation failed

I am at a complete loss of what could be the reason for this, what (if anything) I am missing or not doing correctly?

Honestly I'm baffled... According to every single guide I can find anywhere this process should have worked.

Thanks :)
[Galaxy S 4 Q&A, Help & Troubleshooting] XxLordxX:
Hi,

I'm using the AOSP on a GT-I9505 (not the GT-I9505G!), and I can tell you that there's no difference in data partition, due to the ROM not being able to repartition it and no developer tried to do it (very risky process). I have the 16GB model, which comes with 9.92GB for data and 2.85GB for system, the system partition has "only" 2.16GB free lol. So my suggestion is to you get the Google Edition (you'll install a Custom ROM anyway) and a 32 or 64 GB sdcard, and as you will install a ROM you'll have root access, so install an app called FolderMount, to put app data in your sdcard.

Hope it helped ;),
