Flashing Stock ICS v4.0.3 and then proceeding to JB would be the best thing IMO

Updating to new firmware/kernel

Hey all so after I update my firmware to XWKK5 do I have to wipe everything while in recovery mode is it really necessary?
What do you want to achieve with deleting all from recovery?
If you've upgraded, then the phone is in the version upgraded. If you delete all from recovery, you have to reinstall the entire ROM or the phone wont boot...
Thought I had to Wipe Data / factory reset and Wipe Cache Partition?

Instructions are to be followed .
Custom roms usually ask for wipe but not stock roms .

You don't need to do that if you are upgrading from a Stock ROM. If you chose the wipe version of ROM for flashing then it'll automatically wipe you device. If you use non-wipe it'll upgrade and everything remains same.
Wipe is only recommended when you are switchin from Custom to Stock or vice-versa else after a version downgrade say KK5 to KJ3.
Hope it helped.

happens with almost every rom...i've tried everything wipe data/factory reset, wipe cache, wipe dalvik nothing works!!
Do you wipe data,cache and dalvik before flashing?
Try to wipe data,cache and dalvik after you installed a Rom

Does it start normally after you wipe after you flashed?
I would try to flash stock 2.3.5 GB or 4.0.3 ICS with stock recovery and the flash cf root with odin.
Try this and then try flashing some roms

[Q] How to install this rom? xD

Hi guys, you can tell me how to install this rom? http://forum.xda-developers.com/showthread.php?t=2012666
What kernel should I use for better results?
I think like any other rom...
Put it into your sd-card, reboot to CWM and do the wipes(Factory reset, wipe cache, wipe dalvik cache, format system) and the install the .zip
But first of all you should flash the kernel which is given in the download(together with the rom)
AW: [Q] How to install this rom? xD
I think he better should not format system
Just wipe data/factory reset, wipe cache and advanced -> wipe dalvik cache!
Sent from my Nexus 7 running Android 4.2.1
I'm doing it everytime I flash a new rom
Nothing wrent wrong :fingers-crossed:
Any ICS kernel is compatible. I strongly recommend MESA Hybrid v3.5 or LuPuS v3. I also recommend to format system before flashing new ROM. I've done it over 100 times safely. You'll avoid a lot of problems.

I think he should first do it without wiping system and incase it was required and he stuck in a bootloop, then he can simply do the process again with wiping system
Press THANKS if I helped,
Regards,
AJ
I tried the rom(with rage kernel 3.2), and always go in bootloop
make sure u already have ur ROM on sdcard and the others (wifi-fix.zip or whatever)
on CMW, u can safely wipe /system when u wanna flash new ROM, but REMEMBER not to reboot your phone AFTER u wipe /system. if u do this, u will see "new boot kernel animation" a.k.a BOOTLOOP.
after wipe /system,/cache,/dalvik,/data,/sd-ext then next thing is install ur ROM.
if u using TWRP, its not necessary to wipe /system bcoz TWRP will wiping /system by itself when u install new ROM.
yes, i sent from my phone using Xda Premium, so what?

[Q] Downgrade from CM11 to Jelly bean 4.1.2

Hi guys im an xperia s LT26i user and i have an unlocked bootloader. Im currently running cm11 rom by raymanfx. The last time i tried to flash 4.1.2 rom i did NOT wipe system and i ended up getting a bootloop and soft brick. So if i am running cm11 and if i want to downgrade to 4.1.2 do i need to wipe system, data, cache and dalvik cache? cache and dalvik is a must but if i wipe system and data will it work?
You should make a full wipe probably everytime you switch your ROM. So:
- factory reset
- wipe dalvik cache
- format system
So your entire system is clear and if this don't work flash latest Stock ROM first and then the ROM you'ld like to run on your phone

Ok so i formatted my whole phone with the suggestions you gave and when i flashed the existenz rom by niaboc79 which is the stock rom it says "E:Error executing updater binary" and "Error flashing zip" and im on TWRP Recovery mod version 2.6.3.0
Ok i fixed it i just had to flash doomlord kernel which gets me back to cwm then flashing again fixed the problem. Thanks alot for your help though it did help me at some stages.
