[Q] I9300 - Laggy Phone - Galaxy S 4 Q&A, Help & Troubleshooting

[Edit] Big mistake in the thread name!! It is of course a I9505 phone, sorry for the inconvenience.
Hello everyone, please excuse me if my English is not perfect, it's not my mother tongue.
I looked in the forum and I couldn't find an issue similar to mine, so I hope you'll help me to solve this problem and to find what's wrong because I'm really stuck.
My phone is a S4 I9505. I was running Cyanogenmod 11 M7 and everything was fine. But I updated to CM 11 M8 and my phone began to lag but after a few minutes the lags was disappearing. But a few days later it began to be too Laggy so I flashed the phone to reinstall CM and at my surprise it was as Laggy as before the flash!
So I tried to install an other custom room (Google edition) and I had the same problem.
Now I have a stock Rom and it's running fine. But I don't understand why my phone can't handle a custom Rom...
Can you help me?
Thanks a lot for you future answers.

I had same problem and I solve it .
First, try install any AOSP/GE ROM, CM11 if you like.
Then format your ext SD Card (you can backup data from SD Card to PC) and it should help

Thanks a lot, it works !!
Tou're a genius. :highfive:

[Q] Imperium ROM SG S4 question, updating! (4.4.2 KK)

Hey!
New to the XDA forum, not new to Android!
I will cut to the chase and explain really fast what I need help with.
I have been using the Imperium ROM 4.4.2 KK for a few weeks now and I love it.
But as of a few days ago, Update 4.0 (up from 3.6) was released, and my phone just won't stop spamming me with "upgrade to the latest version 4.0!" . However, as far as I can tell, I have to re-download the 4.0 ROM and flash my phone entirely over again.
So, TL;DR:
I am using the Galaxy S4 Imperium 4.4.2 ROM 3.6 and I want to;
a)Upgrade to 4.0 without re-flashing my and having to re-install all apps, backup photos etc.
b)Turn off the spam notifications about updating.
Thanks in advance, sincerely

Guys come on. These are really basic questions.
- If you are not prepared to wipe everything from time to time, then you should stay away from custom roms.
- You can just try it yourself if it works. Make a backup and flash away. If you got problems, fully wipe and restore your backup.

[Q] Flashed N9006 with AOSP, no baseband now

Hello dear xdaers,
I have an n9006 which I have been using with Omega rom for quite a while. And the phone itself is a genuine n9006, not a clone, I checked the first day.
I just recently decided to get my hands on a new rom and get the kitkat feeling so I have tried some custom roms and they worked fine. Then I decided to try an AOSP rom, W03 Slimkat v23 (http://forum.xda-developers.com/showthread.php?t=2638116)
This thing seems really well working for me except for one little! problem and it is the fact that there seems to be no baseband. And the status page shows unknown for practically everything except wifi.
In the light of this I panicked a bit and flashed latest stock rom from sammobile with odin. Everything works fine again (except the exclusion and the effort to make sure google services stay away. I remember struggling a lot to get google playstore and services installed. Then giving up and installing omegarom which kept me going for a while)
After this I backed up EFS and Radio from twrp recovery and flashed the W03 Slimkat v23 again, did the restore from the recovery and bam!
nothing.
Everything seems to be the same. I went back and forth between stock and slim and couldn't fix it.
The thing is I have nowhere the knowledge level of the users in this forum and I just have to learn all the things like odin and recoveries and download modes in one day and apply them. I probably am missing some fundemantal stuff. (heck I don't even know if EFS and Radio has anything to do with baseband) So please feel free to correct me on what I'm doing wrong and thanks in advance!
Update: I just tried to flash slimkat NON aosp version : http://forum.xda-developers.com/showthread.php?t=2669713
Same thing all over.
Backup EFS

[Q] Roms ( New user )

Hello everyone I'm new here I just recently rooted my Galaxy S4 i9500 and I want to put in cool speedy Rom.
I also heared that I can combine it with lolipop or something? I dont realy understand it yet I hope you can explain it to me help me choose what's best for me without bricking my phone....
Also I would like to know what apps I must have after rooting or what apps you recommand for me?
Any help will be aprreciate thanks for all !
Start reading as much as you can on this forum and learn from it.
You won't brick your phone, that's almost impossible. That has never happend when flashing custom roms.
Just flash a custom recovery for the i9500 and start flashing the rom you want to try. Always read the first post of the rom and probably the last few pages of the thread.
First of all thank you for the reply, Finaly!
Someone offered me the omni rom with lolipop.
I mainly looking for speedy tweakinish rom and it seems awsome,
but maybe there more roms even better?
also I saw you need to delete anything from the phone
b4 you put a new rom so my question is how I save the
important apps and data and if i can skip all the crap i used to have??
Question
Hi! I have a Galaxy S4 LTE (I9506) and i'm on stock rom (4.4.2, I9506XXUCNF3). I successfully installed a TWRP recovery via ODIN. Root done and it works. Now i want to flash the PAC lollipop ROM. Do i need something else to do before flashing? Thank you in forward!

S4 restarts when slightly moved after flashing rom

Hey guys,
I'm new to these forums. Therefore, I've been using a lot of your answers to other people as solutions and tutorials.
I have just install my s6 port on my GS4. My I337M will work fine only if it stable. In other words, if I move it, it's making a quick restart and it's just with the rom installed.
I have tried getting back to stock rom and it didn't have this problem. The thing is that I really like what how Albe95's ROM changes my phone. It's awful and I can't enjoy it completly.
Hope you guys have something.

Unfortunately (app) has stopped

Hello everyone
First of all sorry for my bad english and also go easy on me. Im still a noob
I own a note 3 n9005 and i have successfully installed the darklord n5 costum rom. It works fine and i love it (thanks to the developer) but here is the thing. Since ive upgraded to lolipop from kitkat, 90% of the games that i used to play on kitkat now gives me that damn "unexpectly app has stopped" error.(hd games mostly. Like modern combat 3,4-amazing spiderman 1,2 etc and some apps that i really need) I tried and flashed the official lolipop rom but still gives me the error. It's so annoying and ive tried everything. (Clearing the data and cahce and fix primission) but i havent figured it out yet.
Thanks in advance
And again sorry for my bad english
