Please dev explain wipe which items for flash custom Roms by two.explain category wise for lollipop Roms ,marshmallow Roms and mi Roms.in some mi times full wipe necessary and after reboot into recovery and some marshmallow based on cm Roms after wipe all other than system but after flashing rom only rebooting ,rom is not start so I confused so explain in details if possible.
I asked for flash Roms by twrp
Clean flash: Wipe Dalvik, cache, system, data
Dirty flash: Wipe Dalvik, cache, system
Wiping internal storage isn't necessary usually. I never had a problem.
Also, when changing ROMs, ALWAYS clean flash.
You can dirty flash if it's just an update to the SAME ROM.

You need to read custom ROM threads very carefully before flashing because every developers always include flashing instructions in their thread.
So I don't think you need to ask this question

when updating a firmware?I usually wipe all the 4 options and end up losing all my apps and SMS and stuff.
So, are all 4 wipe options to be performed?and is it normal that i have to reinstall apps each time CM is updated?
If i am not mistaken you do not have to wipe from CM rom to CM rom as of 4.1.99.

Correct, as long as that's what Cyanogen states in his directions. Occasionally devs will release a ROM that makes very significant changes that do require a wipe.
That being said... OP, all you need to wipe is the system itself. You'd only need to wipe an ext partition prior to flashing a new ROM if you had Apps2SD AND the dev recommends a wipe of system.
Disclaimer: I'm used to my old Evo 4G and use a triple wipe script built into my recovery (smelkus) whenever I flash a rom. It pretty much wipes everything.
For the Nexus 7, what needs to be wiped to flash a rom? I did a factory reset, wiped data, wiped cache, wiped system, wiped dalvik-cache, and then flashed a new rom, but I wasn't sure if all that was necessary. I'm using the latest TWRP recovery.
If I'm moving from one rom based on a jelly bean version to another based on the same version, am I ok?
Can I assume upgrading to a new version of the same rom that I don't have to wipe? (I know this one is rom specific, but in general.)
Can I leave data and will that retain my apps? Otherwise, I use Titanium Backup religiously on my Evo and now on my Nexus 7.
I searched within some of the rom instructions as well as the rooting guides, but didn't see anything specific as to what to wipe. Some threads seem to say just factory reset and maybe dalvik-cache.
Instructions with what to wipe usually come in the original post of each ROM. Usually the same ROM with different version only requires a cache wipe while moving between different ROM's requires a full wipe/reset + dalvik.
Worse comes to worse you try something and it doesn't boot and you get back into recovery and fix it.
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
Mirko (NemesisMF)
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.
is there a way to update ROM instead of doing fresh install?
I have unofficial XenonHD for S7 edge
https://forum.xda-developers.com/s7-edge/development/rom-xenonhd-t3544403
And I have Feb 25 ROM and dev recently released March 5th ROM, which fixes number of things
I need help with updating ROM but it doesn't support OTA because it's unofficial version.
Does anyone know how to update this ROM without resetting anything or staring fresh?
for updating the developer has put in this comment.
. Make a full wipe (system, data, cache, dalvik-cache). If you're updating ROM or have other 7.1.1 already you may not need to wipe data (just wipe system, cache, dalvik-cache)
try doing it without wiping the data as per the developer instructions but make sure you have a back up available in case of issues.

Ahh thank you.
Do u think I need to reinstall GAPP softer flashing updating ROM?
Ok, so I am not new to flashing rom but for some reason I am having huge issues trying to install clean stock OOS 5.1.4 rom. Just want to double check I am not doing anything stupid since I mainly been flashing custom roms (xXx rom mainly).
So I simply wipe dalvik/ART cache, cache, system and data (want to start off completely clan) then flashed the OnePlus5Oxygen_23_OTA_037_all_1807181258_7b4b6.zip file in TWRP.
I am currently on the latest blue TWRP and after flashing, it will try to boot but reboots back into TWRP. I have tried the zip file from a number of sources and they all do the same. Am I missing something here?
UPDATE: I did do something stupid after all. I forgot that my Oneplus was decrypted. So all I had to do was go into TWRP and go to Wipe and format data to re-encrypt it.

When starting fresh, wiping of internal storage should be considered. I recommended 2 guides here https://forum.xda-developers.com/on...nos-beta-1-android-oreo-t3710003/post77205633
