Phone very "laggy" with stang5litre rom - General Questions and Answers

I just flashed my wife's Galaxy S4 (SCH-I545 ) with stang5litre's Lollipop rom (see: http://forum.xda-developers.com/galaxy-s4-verizon/development/stang5litre-ediition-5-0-t3132555).
I have the NK4 bootloader with Safestrap installed. The previously installed stock OS was 4.4.2. I installed Stang5litre's rom over the exising ROM using SS (in other words, I DID NOT use a new ROM slot).
The method I used was (from the ROM's announcement page):
If coming from any Rom Before OC1 Ex 4.4.2 or Below
1. Boot into SS
2. Flash stang5litre 5.0 Edition v2NON-MDK Rom.zip
3. Flash OC1_firmware.zip
4. Flash SuperSU v2.49 Beta
5. Flash OC1 SS/FF Flashable kernel.zip
6. Reboot system.​
Everything seems to be working okay, but the apps take 10+ seconds to open. Once open they seem to run normally.
Any suggestions?
Also, the instructions included nothing about wiping the phone before flashing, so I did not do it.
Should I have?
Would this ROM/method still work if I did a wipe to factory settings before installing?​Thanks.

You apply al wipes? Data,system,caché, dalvik cache?

[Q] Root + Custom Rom

Hello Everybody!
I am new to android and this rooting/custom recovery scene. I have rooted my Nexus 5 on 4.3, updated to 4.4 then rereooted, but that's it.
I have now done this:
Previously running stock android 4.4.2 with root/unlocked bootloader/TWRP/SuperSU working great
Wiped device (via TWRP bootloader)
Flashed custom rom (Omnirom, 4.4.2)
Installed SuperSU from gplay store
I opened SuperSU and it says I'm not rooted. What have I done wrong? And can you help me understand this process, because evidently the custom Rom (or the wipe beforehand?) broke my root. Can I get it back without flashing Omnirom again?
Thanks!
Adam
P.S. Anybody know a good Multiwindow Rom for Nexus5?
Download and flash the SuperSU.zip through TWRP from here
Then when you open SuperSU should work. You can apply this same procedure for most ROMs if they don't come pre-rooted like Omni.
Additionally, there is a setting which you should tick "Install SuperSU backup script" which means it should remain rooted after you flash an OmniROM delta update.

[Q] Update to Lollipop without USB and with root

Hi, my N5 has a problem, it has the USB port broken so i can't connect it to the PC. It now has KitKat 4.4.4.
Here is my problem:
I want to update to Lollipop but i can't do it with Factory image and/or Sideload because the USB problem.
I tried to "unroot" but i couldn't do it right, i've downloaded the 5.0 OTA and my phone rebooted with a red triangle and it said "error" i know this is because i still keep my phone rooted.
So i would like to know 2 things:
1) How do i unroot definitely? because i did it before but it seems it didn't do right, i clicked "unroot" on SuperSU (i read that sometimes when you press "unroot" it doesn't erase all the folders and files so you have to do by your own, but what files and what folders are they?)
2) If i unroot and i if update to Lollipop, can i be root without using the USB port?
Of you're rooted, why would you want the stock ota anyway? There are PLENTY of 5.0 Roms in the development section with custom kernels (custom kernels are needed in 5.0 lollipop for root). Flash one of those in recovery. Make sure you have the latest TWRP which you can flash with flashify if you can't fastboot flash using USB.

Is really needed to flash a custom kernel to get root on Lollipop? I'm asking because in this thread [ROM] [STOCK] Android 5.0 LRX21O - Stock/Flashable (11/12/14) FAQ nº 2 it says:
Q: How do I get root?
A: If you want to keep the stock kernel, use CF-Auto-Root. If you flash a custom kernel, just flash the newest SuperSU ZIP afterwards.

So i understand that we can have root with stock kernel, is this ok or did i misunderstood something?
If i want to flash a custom kernel, where can i get "SuperSU" Zip to get root? and does it need to clean something after or before flashing this file? caché, data, etc?
Yes CF AUTO ROOT will allow your to root the stock image. However since youre already rooted youre running into issues flashing it successfully. I attached the SU zip below. My recomendation is if you want the stock ota image, download it from the developer thread, flash francos custim kernel for lollipop ans then flash the root zip i have attached below. I would complete a full wipe of system, data, and both caches (not internal storage or you will lose all on sd card) before flashing. Once you wipe just flash the the rom, kernel and root zip in that order.

It worked perfectly!
I tried first with CF AutoRoot but it failed, but it worked with SuperSU.

Hi,i would really appreciate it if you could just spare some few minutes of your time to help me out with my phone.
So I bought this barely used Samsung Galaxy S4 (i9505) from a guy. It came with android 4.2.2 and a boatloader/Baseband of SC04E0MUAMG2 and when I boot on it shows ntt-DoCoMo before booting up (so am guessing it was locked before, it came unlocked because every SIM I have tried has worked, and also it came rooted).
The issue is I really want to upgrade to Stock Lollipop or a custom lollipop rom like Aurora or Albe95 roms, but each time I try flashing a stock rom using Odin, it says fail (usually its when it gets to ' NAND write start, Auth fail '). Since Stock refused working I decided to try Flashing a custom rom using a custom recovery, it flashed successfully but when I tried flashing the modem and boatloader for the custom Rom, Odin would show fail again, I tried if on every port on my system and even unticked F.reset and auto-reset, but the result was still fail.
So I bought mobile odin pro to try out the stock again, it did install the stock but it was buggy, camera wasn't working, Mic wasn't working, the back button wasn't working. I just had to remove it. Currently am on Imperium 12.1 custom Rom( i installed it because it didn't require flashing modem and boatloader. The only problem is camera and Mic still won't work on this rom, but when I go back to the backed-up android 4.2.2 everything works fine. So yeah, that's my predicament. I am clueless as to what to do next so please help me out. I would really like to use a stock or custom Rom.
Am having a bit of an issue here, I followed the steps listed here to install a custom lollipop rom, I finally got my camera and microphone working after I flashed that Laneham but my wifi (which was working with the custom rom before) is refusing to work now. It won't come on. Is there any solution for that? Have tried doing a data reset and wiping my internal memory but to no avail.

If you want to use stock lollipop rom, you have to flash the lastest offical rom(SC04EOMUGOI4 ).
First, you flash the stock rom, you will find everything works well except back and menu button. If you have other problem(eg. wifi does not work), you may try flash the stock rom again.
Second, fix the back and menu button problem. You can find solution here.
Then, you can enjoy the stock lollipop rom.
If you want you try other custom rom based on lollipop rom. Please follow this post.
And you have mentioned, your odin did not work via PC, sometimes it is caused by usb cable. You can try with a replaced cable, buy one or two repalced usb calbe, and usually it will help you solve the problem.
If repalced usb cable can not work, you can try with other computers.

[Q] Xperia L Lollipop

Hello Guys,
Need your help. Please help me out here.
My wife has a Sony xperia L which is still running Android 4.1.2 version. Now I rooted it with Root kit and tried flashing various Lollipop Roms like Cm12,primexperia and resurrection. But wifi does not work on all these Roms
I have tried almost every solution available on Xda.
I have used multiple custom recovery, N number of kernals and have flashed Boot.img and Thunderzap 4.16 from recovery after flashing the Roms. Still not luck.
Steps followed for flashing the Rom
1.Rooted with Rootkit and updated Supersu binary
2.Installed Busy box with Flashtool
3.Flashed a kernal (Tried TZ 4.14,4.7,4.8 Extended stock kernal and some more)
4. Booted to recovery ( Tried Cwm, TWRP, Philz)
5. Wipe data and all for clean installation
6. Flashed Rom zip (Cm12, Omni 4.4, Primexperia, Resurrection)
7. Flashed Gapps (As per the Rom)
8. Flashed Supersu zip to regain root access
9. Reboot to boot into new Rom
10. Wifi is not working so flashed boot.img from Rom via flashtool
11. Flash TZ 4.16 in recovery for cm12 ROMS.
Still wifi not working not sure what is the issue. It's working fine in Stock Rom.
Now I am upgrading to 4.2.2 via Sony update software.
Masters please help me out here. I can think of 2 solutions now.
1. First update to latest Sony official update (4.2.2) and then try again.
2. If there is any firmware file for stable lollipop version (with system.img, data.img and boot.img) which can be flashed using flashtool.

How to flash stock ROM in XT1040?

Hi, I've read many guides on how to flash stock roms and stuff, but I'm still not sure how to do it in my case.
I bought an XT1040 from a guy and it came with bootloader unlocked and Lollipop 5.0.2 (CM 12-20150126-NIGHTLY-peregrine)
I wanted to install the stock LP rom, but then I found an optimized version on this thread: http://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-lollipop-rom-t3142816 I think that would be better, but the problem is I'm following this guide to install a stock rom: http://forum.xda-developers.com/showthread.php?t=2542219 but it says you have to flash every file, one by one, yet this .zip I downloaded (Retail Latin America 5.1 ROM (Optimized) v1.0a (331mb)) only has a "boot.img" and some folders named "supersu", "system" and "META-INF". Does that mean I have to flash the whole ZIP in the recovery? (oh and btw I installed TWRP v2.8.7 [recoverytwrp2-8-7encryption.img] using adb, I didn't wipe the other recovery with "fastboot erase recovery" because this had CWM already installed... is that okay?)
What should I do?
In short:
I have a bootloader unlocked phone with Lollipop 5.0.2 (CM 12-20150126-NIGHTLY-peregrine) and CWM
I flashed TWRP v2.8.7 without wiping recovery (at least I think that's what "fastboot erase recovery" does)
I want to flash a stock rom (optimized) with LP 5.1 from here http://forum.xda-developers.com/moto-g/4g-development/rom-stock-motorola-4g-lollipop-rom-t3142816 (Retail Latin America 5.1 ROM (Optimized) v1.0a (331mb)) but I'm not sure what to do.
Thanks.
_______________________________________
I just decided to do what the guide said:
1) Boot into latest TWRP and Format Data (Wipe > Format DATA > Yes) - This step is essential, and will wipe Internal Storage (Downloads, Music, Photos etc, **backup important files**)
2) Transfer ROM to SDCARD or Internal Storage. This may be done in Windows via MTP, or using adb sideload or adb push ROM.zip /sdcard/
3) TWRP > Wipe > Factory reset and flash ROM.
4) Reboot.
5) Call / WiFi issues can be solved by flashing 5.1 Radio Firmware (Below) for your Model.
now I'm in the step 3, trying to flash the ROM but the bar doesn't fill at all...
_________________________________________
Lol that was me panicking, the device managed to flash the ROM and it's working now, I also flashed the radio firmware so I have working WiFi, but the screen flickering keeps happening each time I reboot the device.
I'll probably want to downgrade in the future... any tip on that would be appreciated.
You don't need to use Fastboot other than when changing TWRP version. Simply flash the Optimized Stock ROM (or any custom ROM) via TWRP. Screen flickering is caused by not having updated your Bootloader - this utility will do that for you: Bootloader Upgrader Tool.
I highly recommend you try the following optimized Stock Marshmallow ROM: (It's faster than Lollipop)
