Help S5 Running dog slow

hi i wanted to see if anyone else is having a similar problem to me with their S5

Its been running 5.0 for a few months now and I did a clean install when I upgraded it.

however over the past few weeks at times it runs horrendously slow to the point where when you try to put your pin in to unlock the phone it displays a set of white blocks instead of numbers

I am regularly running Ccleaner on it and rebooting the phone but soon after the same thing happens

Any ideas

Cheers

Bart
 
so i am using the G900F

Bootloader G900FXXU1POD1
CSC is G900FEVR1POD1
PDA G900G900FXXU1POD1

i dont use any task killer apps

dont use those apps.

Can anyone suggest a firmware I can try even if i have to root the phone please
 
Thanks for this

So I see the link to root the device using Chainfire method
Is TWRP - used for back up and restore ? If so where do I get this and how to install?
And where do I find the Cyanogenmod 12.1. firmware?

I need to do something its driving me nuts !!!!!
 
So I think Ive managed to do the first part and root the device

Ive then installed twrp

Unsure whether I now need to boot direct into twrp or I can launch it from within the phone??

When I have tried to boot into recovery I don't see twrp and the Android figure is on it's back
Other than just installing twrp from the store do I need to launch and do anything with this app before I use it to locate the firmware that I want.

And finally to confirm I would download the new firmware to the phone on a SD card or onto the laptop and navigate to it via twrp.

Sorry for the questions, first time I'm trying to install a non stock rom on a phone
 
Update so I have gone ahead to try and install twrp by launching it from the phone and then trying to install recovery, however after it finishes downloading the file I get a message stating

Please confirm your partition.... Etc and then gives a path name

Ive no idea here. Help please
 
Update:E:unable to mount 'data'

managed to root the device and install TWRP
then managed to boot into TWRP
I then tried to create a back up and get the error E:unable to mount 'data'
what does this mean?
am I still ok to go ahead and try and flash the rom?
 
have also tried a new micro sd card
and tried to format it using NTFS, exFAT and FAT32

also to double confirm I am trying to create a back up to the micro sd card and NOT the local storage

I read somewhere about using ADB to install the ROM but wasnt sure about this

any more ideas gents??

You can format a new SD card in the phone... Settings > Storage > Format SD card

Are you talking about a nandroid backup or a Titanium backup or something totally different?

Most, if not all, custom ROMs are flashable .zip files that are installed via TWRP. You will need to read the ROM developers installation instructions... slowly, carefully and thoroughly!
 
ok will format through the phone and try again

i was just trying to make a nandroid back up - do i need to? as I knwo the phone will be wiped in any case

am i safe to try and flash the Cymogened rom?

ALWAYS! ALWAYS! ALWAYS! make a nandroid backup to your ext SD card and even copy it to your computer or upload it to Google Drive or DropBox as well, before doing anything on your phone.

So long as you carefully and thoroughly read the installation instructions, and follow them, first.
 
ok so at the moment i cant make a back up using TWRP as i keep getting that error

what do you advise? otherwise I wont have a back up?
 
thank you ill try that now

also to confirm once i manage to create my back up to install the ROM I would do the following

- copy ROM to sd card
-boot into TWRP Recovery
- Choose WIPE partition and wipe the local partition
- then choose INSTALL - navigate to ROM, follow instructions and Flash?
?
 
damn damn damn

so i downloaded and ran the fix you suggested which says it worked on the phone

then booted back into TWRP and went to create the Nand back up

however agsin i got the Red E:unable to mount messages , it tries to create a back up onto the micro sd and then fails at the end.

Can i back up to the laptop?
