Steps to follow before flashing a new rom - Nexus 4 Q&A, Help & Troubleshooting

Hey guys, im currently on paranoid android and want to try the xenon hd rom, i read it's recommended to do a full wipe before installing a rom if your running a different rom. Is there any steps I have to do other than a reset, flashing the rom and the gapps, plus the wiping of the cache and the delvik cache?
Regards.

its always recommended to make a backup(nandroid) of your current rom before flashing anything, just in case. backup, wipe data, flash the rom, flash the gapps or kernel if needed, reboot and profit. you dont have to wipe the dalvik/cache because when you flash a rom it automatically wipes it anyways.

One little thing to add to what simms wrote, whether it's recommended or not in the corresponding thread, when you move from one rom to another a full wipe should be a golden rule.

[Q] Question about updating ROMS.

So I've flashed between ROM's a few times now, but never updated a ROM that I am already running. Was curious if I have to do a full wipe before the update like switching between different ROMs, or can just flash the newer version over the older version? If I don't have to do a full wipe, do I still need to wipe the cache and Dalvik? Thanks!
Cache and dalvik.

should i do this before or after flashing the rom, updating from PA 2.99 b8 to b9. thanks
Before.
All ROMs have threads, those threads have op's, they are usually full of the info you need. Each rom is different and requires a different approach.

Help a noob

Good day guys/girls
I am brand new here as you can see in my total posts.
I am also new to android coming from crappy IOS.
I own a Galaxy S4 I9500, the device is rooted and has philz_touch_5.06.0-i9500 CWM on.
I want to install WanamLite rom and Adam kernel....but have no idea how to do this.
I am using this page for the downloads http://forum.xda-developers.com/show....php?t=2268569
Which one should I run first, the rom or the kernel?
Baseband I9500XXUAMDE
Any pointers and directions would be appreciated greatly.
Adam kernel is included in This rom. Download Rom on sd Go to recovery wipe data/factory reset, wipe cache, Wipe dalvik. Then install Zip. But First backup everything. And Make a nandroid backup
Thanks for the reply, is this the ROM GT-I9500_WanamLite.XXUBMF3.V1.4.NO-WIPE.zip ?
Yes that.

Its up to you, you can try a "dirty" flash and not wipe and see how it goes, If there are problems then do a wipe.... If you don't want to set up your phone again then make sure you have a nandroid backup and stay on the older version.
Some people need a different modem because their reception is no good with the new modem or it causes battery drain. This would be the reason you would flash a new modem. Easier to leave a lone and see what happens, you can flash a modem.bin file later if needed through ODIN or, my preference, Mobile ODIN....
Read the changelog in the thread to see what kernel is included...
1. Should I do factory reset, wipe cache and wipe dalvik when upgrading from 9 to 10?
You should full wipe when flashing a new rom, but wiping cache and dalvik cache will wokr fine too
2. Why should we flash modem seperate than rom ?
Because each modem works different from other in your region
3. Which kernel will be included in omega 10?
Modified kernel based on stock one
U don't need to do a factory reset specially upgrading from 9 to 10 cause both 9/10 are 4.2.2 based Roms and moreover they are from the same developer.... As for wipe/dalvic cache, the installer does it itself...
Simply go into recovery and flash the file... U should be good to go...
Good luck!

Sorry to hijack this thread but do we need to change gsm and lte modems if getting poor reception after installing omega (I have installed omega 19 and getting poor recption ever since)
Thanks

2 quick questions regarding TWRP and the Pardus rom on the LG G2 (D802)

Hey guys, I just had 2 quick questions.
1. I'm using TWRP and the first time I rooted and installed the Pardus rom, the factory reset worked perfectly. However, now if I try to factory reset and wipe cache it always fails. Any ideas on how to get past this?
2. This one is for users of the Pardus rom for the g2. I'm currently using the "reborn" build, I'd like to switch to the "classic" build. Would I have to wipe all my data in order to do that or would just wiping my cache and flashing the rom work fine?
Thanks in advance for any assistance and please pardon my noobiness with regard to the above
If the base of the roms are different make a full wipe.

GAPPS remover tool for Pure Nexus - layers- marshmallow

Currently I m on Pure Nexus (6.0.1) rom.. it's really amazing in smoothness.. I have installed Bank's gapps.. all is well till now except battery drain.. it's almost 1.5 times more than my stock LP.
So I want to remove gapps..
I know that I can reinstall rom after wipe and not install gapps that time..
But that can take time as I ll have to reinstall all my apps and data again..
I was using gapps remover on gingerbread roms..
Is there any gapps remover tool which can save me from all that reinstallation trouble?
I just want more battery life and not to charge my phone twice in a day..

Just dirty flash your ROM and don't install GAPPS. Problem solved!
