[Galaxy S 5 Q&A, Help & Troubleshooting] alwathekahmed:
First of all, I have flashed this rom and it's really laggy on our S5

Two times, I flash it, only one or two days and return back to AOSP based rom (Lineage 14.1,Ressurection remix 5.8.4)

Anyway, I want to help you to boot this rom on your phone as it's really nice to test the new Dream UX and this ROM especially doesn't have problems more than:

1.Ires scanner (can't run on our phone)

2.Finger print scanner (on lock screen only due to different s8 finger print scanner driver)

3.the hell much lag in the ROM (and others N7/S8 based ROMs)

----------------------

I think that you shouldn't have wiped the system partition

When I flashed it, I wibed only: (data /cache /dalvik-art)

Partitions, as I remember the developer of the ROM didn't say to wibe system partition

-----------------------

If the above didn't work then you will have to flash the stock firmware and flash the TWRP recovery then install "Nemesis reborn v4" ROM again

WARNING! During the process the whole internal storage will be

FORMATTED

:eek::mad: Which mean that all your data on the internal storage will be erased (Your external SD CARD won't be affected :good::laugh:)

Don't worry because it isn't too hard, just follow the following steps:

1.Open your browser:laugh::laugh::laugh:

2.Go to www.sammobile.com

3.tybe the code name of your device in the search bar: (SM-G900F)

4.Choose your current CSC,which is based on your country, if don't know it, I recommends the BTU for you

As it's the best one for the European S5

5.download the latest release:(Choose the latest one-press normal download-sign in or register if you didn't-wait 10 seconds- the download should start now)

-Note: download size is about 1.5 GB or more (I'm sorry I don't remember how much it was)

6.extract the downloaded file using winrar or any .zip extractor (now you should have a 2.5 GB or less/more with the extension of .tar.md5)

7.download odin for pc (I don't remember the version but you should have downloaded it to install TWRB recovery)

8.open odin, press (PDA)

OR

(AP)

(Due to the difference between odin versions, the PDA button can be called AP in the Modern Versions of odin)

9.Choose the file that you have extracted

(with the extension of .tar.md5)

10.boot into download mode by turning off your phone and pressing on the (power-volume down-home) together in the same time until the phone boots and you see (booting download mode) in blue on the top left edge of the screen

11.plug your phone in the computer via the USB cable

12.There is a section called ID: COM (on the left upper side of the window in odin). The blank space underneath it will turn blue if your device is recognized. (If the phone is not recognized make sure you have installed the correct USB drivers for your device)

IMPORTANT! Do not place anything under the PIT section and make sure that “re-partition” is NOT checked. (On the left side you will see re-partition under the Options tab)

13.Once you are able to see that the firmware file is loaded onto Odin and your phone is detected, you can go ahead and press the “Start” button at the bottom of the application to being the installation process

IMPORTANT! Don’t touch the USB cable while the firmware is being flashed on your Galaxy device. Unplugging the device from the computer during the installation process or closing the Samsung Odin application mid-process can have undesired consequences

14.At the end, you will see a message saying ‘PASS” on a green background. This means that the installation is done. The device should reboot automatically and it should now be running on the latest stock firmware

IMPORTANT! If your device is stuck on The Samsung boot logo (not the splash logo) then remove the battery and boot into the stock recovery and wipe data/factory reset and wibe cache and reboot to the system

15.Wait around 15-20 mins and setup your device as it's new

-Now you are on the stock firmware, 50% of the process has been completed by now

16.Root, Install TWRB RECOVERY,Wibe: (Data/cache/Art-dalvik cache)

DO NOT Wibe System partition

17.Install the "Nemesis reborn v4" ROM normally

18.Reboot and wait around 15-20-25 mins,and then setup your device again

--------------------

Info:there is someone who ported an updated drivers for our GPU (ADRENO 330) from the Nexus 5

The updated drivers gives you 30% better performance

on touchwiz based ROMs and the stock firmware

For more info and download :

It's a normal flashable zip, flash it after you setup "Nemesis reborn v4" ROM

Note:flash it only on touchwiz based ROMs and the stock firmware, Any AOSP ROM will boot loop with this driver as the AOSP ROMs have the most up-to-date drivers.

Let's say that this drivers will make the ROM near to be a daily driver

I hope that this will help you to pass this proplem and sorry because I said too much but I wanted to help you
