Instructions for customizing the bloatware removal:
Located in "/s5mods/bloat" is a text file named nobloat.txt, Open and review this file it contains a few default apks to remove.
To add your customizations simply add the file name of the apk (Case Sensitive), if the apk also has a coresponding odex
file you will need to add the path to that as well following all case sensitive patterns. Be careful when adding apks to this list if you
add an apk that is required by the system to boot you will be required to flash the stock rom and start over from scratch.

Bug Reports
Please follow the instructions below to report bugs.​
1 - Go HERE To report bugs and request support.
2 - Include all relevant information in the Bug Tracker.
a) Device Model (Tab4 7.0/8.0/10.1)
b) SU version (SuperSU 1.94/1.99 etc)
c) Check busybox version (1.22.1 installed by script)
d) Include a logcat (run logcat during script to generate all errors) CatLog from the Playstore is a great tool.

Hey thanks! Already finished! I was really busy, but before that I actually exchanged my 7 inch for an 8 inch. Does this tweak also work for 8 inch? I am guessing it is because you just said Tab 4 without screen size. Also, you are aware that tab 4 7.0 has Marvell quad core chip while 8.0.and 10.1 has snapdragon 400, right? Just making sure cause you don't have this tablet and maybe you weren't sure.
I'm still deciding if I should keep my ipad and return this tab 4 8.0 or keep this tab 4 and sell my ipad. Ahh can't decide! There are both goods and bads..
Anyway, I'll try this tweak soon. I hope other users will also find this tweak helpful.
Thanks!

tweaks SHOULD be independent of screen size and processor, that being said the performance gain most likely will behave differently between the three devices

yep, ok i dont have a folder specific to the tab or tab4 sorry, it should work for the 8.0 and 10.1 as well.

So ran it on my 8.0, it completed and I'm able to boot successfully, however it was unable to set bootanim, it was unable to remove default bloat ( stated it was read-only), and init.log and the memory recovery.log do not exist in data/local/

You are rooted, correct?
did it install all of the prerequisite components? busybox etc?
you ran this through script manager correct?
chose the SU options in script manager?
did you go in and modify the nobloat.txt (per the instructions)
Remember I don't have this device I am flying blind abd need some detailed information in order to help.

---

I am rooted yes. I also had busybox preinstalled. I did run through script manager as linked, with su chosen.
I didn't touch the nobloat.txt at all, rebooted twice immediately and checked for the two files that didn't appear
The only problem I initially encountered was i am unable access menu of script manager, so i had skipped that step about the text size

you will need to modify the nobloat.txt file for your device (remember I don't have the tab 4 so the txt file is based on my tab3)
you really need to change the menu size so you can see the prompts and answer them appropriately it should work the only reason i can think of that it didnt is that kitkat behaves differently but it shouldnt as far as running scripts go. you mentioned read only which leads me to believe that the system folder did not get write access correctly.
ill look thru the script and see if i can find anything that needs changing

Any updates on this?
I'm eager to see if the "better network stability" helps with the Wi-Fi issues on the tab 4
