I just installed the zip through TWRP and then i wiped data. Is this a clean flash or not?
All apps, settings and data removed. Also root. Only bootloader remained unlocked.
I am on Nougat 7.1.1.
Can you help me pls?? On this install i had 5% battery drain during 8 hours of sleep. Only wifi enabled.. I guess gapps drain to much battery, or its the nougat?? How can i go from 7.1.1 to oreo?
If the factory reset is done in twrp. Factory reset will clear cache, user apps and data that those apps were using, after flashing the Rom. A clean flash is complete.
Factory reset and wipe data/format data has the same effect for clean install?

Hello,
actually I'm using a SGS4 I9505 with cm-12-20150304-NIGHTLY-jfltexx and CWM 6.0.5.1.
I've tried to flash several TW Lollipop firmware wich i found in the I9505 forum:
1. Kushan+Touchwiz+Lollipop+Lite+Rom+v.1.2
2. S4_Echoev42_EchoePop2_020315
3. OA7-2.1F
4. XXUHA07-v2.01
Before flashing any oft this firmwares i made a factory reset, wiped both caches and installed the modem Firmware via Odin.
After flashing firmware # 1 and 2 my phone was stuc in a bootloop (only Samsung Galaxy S4 Logo appears).
Flashing firmware #3 and 4 fails and cwm reports error 7.
Flashing cm12 afterwards isn't a problem and runs fine.
I think the wipe fails or doesn't work properly. Is it enougth to select factory reset in cwm and wipe the dalvik cache manualy?
What can I do?
With besteht regard

What if it is a recovery problem?
Thought about that too.
Should i try twrp or philz?
I switched to Philz Recovery and flashed S4 Echoe Rom v42 without any Problems.
CWM seems to have a problem to falsh TW Lollipop images ower an existing CM12 an the I9505.
You need to do full wipe not just cache.

As I wrote above I did a factory reset before flashing and wiped the caches with cwm. If that is not enougth it would be nice to explain what else I have to wipe or post a link.
While using philz recovery the factory reset for clean system is enougth and the new System is working fine.
Factory wipe is not full wipe, you need to do a full wipe as in format to install new rom, phillz recovery has this feature can't remember exactly where, I think its under advanced.
Just have a look in the sub menus.
Just to explain it better when you do a full wipe it deletes every part of the existing
Rom including the system, data and cache and some other stuff completely removing the android operating system, so unless the rom you install does a wipe before install parts of the existing system will remain and can cause boot issues. For example as you've already discovered you are trying to install a tw rom over an existing cyanogenmod 12 installation which Will cause it to hang on boot.

Do you mean a factory reset from within Android itself? If so, then that's a complete obsolete step. When before flashing a rom you should perform a factory reset, then they always mean a full wipe from the recovery. You need to do a full wipe from the recovery. That means the /system partition is being wiped. You will see it in the screen during the wipe if it wipes /system.
But it also could have been a problem of CWM. I don't think it is being updated anymore, so better use TWRP or Philz.
I have updated my phone to latest official 5.0.1 and have also installed the 355 mb update that came after the main lollipop update Have wiped cached and data and done a clean install yet i still have some of the lolipop bugs..They are as follows:
1. homescreen Wallpaper gets set to default wallpaper randomly.
2. Keyboard crashes few times in a day.
3. Using snapchat and other apps continuously causes the phone to reboot
4. Overheating...phone gets heated like mad.
I noticed most of this happens when I am on 3g and on wifi everything works smooth.
my phone is rooted. Please let me know if there are tweaks or apps that i can install to fix these bugs. Thanks so much!

I think you should try some custom roms which base on android 5.0.1 for S4, suggest Omega Rom v28 .
This will fix those bugs easily

Start with a clean device. Thus wipe your data.
It's not needed to wipe your internal storage. But make sure to wipe /system, /cache en /data (without internal storage).
Hey thanks for your reply. Can you tell me how to wipe data without wiping internal storage ?? Generally when i wipe data or do a factory reset it wipes everything.

Use custom recovery like TWRP.
Hi,
I've recently done a succesful flash of Blisspop after a full wipe.
Now I want to update, but I don't want to do a full wipe. Simply installing the zip on-top gives a permanent booting screen. Can you update without starting from scratch?
Did you wipe cache & dalvik after flashing updated zip?
I did not. Is that the only required extra step? And will I lose data if I do so?

No, you only lose data when you wipe the data partition
In recovery, you'll see different named partitions, cache, dalvik cache, system, data, etc etc
If you wipe System, you wipe the ROM
If you wipe Data, you wipe your user data
Caches are just temp partitions, safe to wipe any time, only side effect is a longer first boot as Android needs to re-cache everything
But yes, you do need to wipe the caches when updating to a newer version of the same ROM/Droid version, and no you won't lose your data
Here's how I do it:
Wipe System
Wipe Caches
Flash new ROM
Flash new Gapps
Flash SuperSU if needed
Wipe Caches again
Reboot
Result = New ROM with no loss of data
That's a clean flash, a dirty flash is how you did it without wiping System
If you are moving to a newer version of android, or a different ROM, wiping data becomes more necessary, especially if the move is to an older version of droid
Thanks. I'll try it out.
Hello everybody
So this is weird asf..
So I got Mi 9T with MIUI 10.3.7 EEA stock rom. TWRP and Magisk flashed. I wanted to update MIUI to the latest 10.3.12 and I found a method online to update via TWRP by flashing the new MIUI stock rom then flashing a zip "Lazyflasher-no-verity-opt-encrypt.zip".
I backed up (system, data, boot) and then wiped (sys, data, catch, dal/art), then flashed the newer MIUI rom, then Lazyflasher zip. But I got an error installing Lazyflasher. So I wiped and restored my backup and the device booted into system. But then I discovered that the system is acting crazy. Fingerprint, wifi, all sensors aren't working.. etc.
I tried re-restoring my back ups, and tried wiping Dalvil/Art cache, Data and, Cache (TWRP factory rest) but nothing changed.
I'm considering flashing stock room but I don't want to lose bootloader unlocking and wait again.
Any suggestions?
Thanks in advance
H'ola,
so i'm running MIUI 11.2 latest beta from xiaomi.eu on my 9T , rooted with twrp. i like to "reset" the phone, just soft-reset .. deleting everything, a complete wipe.
When i'm using the miui option for it, the phone going to restart into twrp and then nothing happens?
maybe someone of u know, how to do it?
thanks
From TWRP, format data, wipe cache and reboot.
thanks, i was a bit unsure about that .. coz i read a couple of times "never wipe system,data partition on a 9t" ..

I confirm that you should never wipe system or vendor on the 9T, even prior to flashing new ROMs. Doing so causes soft "stuck in fastboot" bricks on many Xiaomi devices.
Wiping or formatting data is totally fine (well assuming you want to lose your data). Formatting data is required after flashing a different ROM or if you want a true Factory Reset.
I just wiped data and cache, it worked.
Thanks
