[Q] HELP!!!

i have a unlocked & rooted galaxy nexus....i flash the rom open kang build 22 & flash the gapps 4.0.4 after i rebooted. i stocked in bootanimation & hang up & appear the google logo, always like that...cannot start.....HELP please....

Wipe and reflash the ROM then Gapps, then boot.

Did you do a full wipe. Wipe factory/data, cache partition and in the advanced menu wipe dalvik cache. Then flash rom and gapps

After you flash the rom, wipe data,cache,dalvik and flash gapps. You cant just flash rom than the 4.0.4 gapps you will get the bootloop.

i already do full wipe & still the same problem?

1. Wipe data
2. Wipe cache
3. Wipe dalvik cache
4. Flash ROM
5. Flash Gapps
6. Reboot

In addition to doing what Eddy says, re-download the rom and Gapps.

I always flash like that never have a problem. Never reflash after flash. Try to flash another ROM OP to see if it was the ROM or not.

Flashing a ROM (JellyTime)

I got a simple question about flashing a rom, at this point its JellyTime.
I'm not really familiar with the order that you need to flash and if you need to flash the kernel separately?
My order is now:
- clean/wipe
- Flash ROM
- Flash gapps
- fastboot flash boot.img (is this step required, or does this already happen when flashing the ROM?)
Then the follow-up question is, does it affect the ROM when you boot the first time with an older kernel?

You can flash the kernel basically anytime. I usually dirty flash kernels with no problem.
Also, no need to fastboot the boot.img. The rest of your order looks fine.

My order :
- format all partitions (except sdcard)
- wipe cache/dalvik
- Flash ROM
- Flash gapps
- fixing permissions
- Reboot
But i think your steps should be fine as well.

How do you fix permissions ?
When I flashed gapps I saw that in the end its fixing permissions. Do I need to something manually ?

You can fix permissions using recoveries like 4ext and stuff...remember to wipe cache and davlik if you are flashing just kernel.

Like he said use recovery 4ext there's an option at "tools".

Wiping cache+dalvik cache is redundant after formatting all partitions. A lot of people have this habit and recommend it, but its unnecessary. Dalvik-cache is located in the data partition. It's nothing special, its a folder there like any other, and contains classes.dex files for all apps on the device. When you format all partitions, data is formatted, so the dalvik-cache is wiped along with it. And the cache partition is formatted anyway. So wiping cache+dalvik again after formatting all partitions is of no use and unnecessary.

You don't need to wipe cache and dalvik after flashing a kernel. I used to do it too, but many times the devs themselves have said it isn't required. Lord Clockan said many times that wiping cache+dalvik is unnecessary after flashing a new kernel. When you think about it, it makes sense. Dalvik cache just contains classes.dex files for all the apps on the device and nothing else. When the dalvik-cache is rebuilt after a wipe, it pulls the classes.dex from each apk and puts it in the dalvik-cache folder (please correct me if I'm wrong). This isn't in any way related to the kernel and what it does. Regardless of the kernel flashed, the dalvik cache will remain the same. So it shouldn't make sense to wipe it for every kernel flash.

Hello, I did all of the steps in this order and ROM is booting OK. But after that I have random freezes while doing different tasks (taking picture, going to settings, after unlock). Do you have any suggestions what can I do/change to fix this. This is happening on all Jelly Time releases - i tried R3, R4, R5.1 and also AOKP V6. When I flash IcoColdSandwich everything is running without problem.
I will appreciate your help. Thank you!

My order :
- wipe data/factory reset
- wipe cache
- wipe dalvik
- Flash ROM
- Flash gapps
- fixing permissions
- Reboot

Thanks, that makes it clear.
So its possible that you flash the kernel when you are flashing the ROM!

[Q] How do I upgrade my CM10?

Total newb question but on the CM10 thread they say:
Instructions:
First time flashing CyanogenMod 10 your device, or coming from another ROM?
Root the device and install ClockworkMod Recovery. Instructions are available here.
Perform a NANDroid backup of your current ROM.
Format the system, data & cache partitions of your device.
Perform a factory reset.
Flash CyanogenMod.
Optional: Install the Google Apps addon package.

.... they don't say how to flash if you are upgrading.
Some in the thread say that they just "dirty flash" it.
What exactly is a "dirty flash"?

dirty flash means you didnt wipe data/cache.
most of the time, you can dirty flash newer versions of the same rom over the older version of the rom you have.
HOWEVER, if you have problems, you need to wipe data/cache and reflash the rom completely

Guess I might as well wipe the cache and dalvik even on a dirty flash?
Thanks

I upgraded from CM10 M1 to M2 with only a wipe of Dalvik cache. Works fine.

I finished installing M2 after wiping both the cache and dalvik cache (figured I would do the cache just in case).
Worked great!
Thanks all

***what Nexus version do you have?*** i've used the below instructions with GSM GNex***
If you're coming from an AOSP CM9 rom, Do the following :
Download Maguro (or your models ROM+Gappsl).
- boot into recovery.
- Preform NANDroid Backup.
- Wipe Dalvik cache.
- Wipe Factory reset.
- Wipe Cache.
- install zip from SDcard>choose zip from SDcard>ROM.zip (your ROM)
- Flash Gapps.zip
- Flash kernel.zip (if you have one)
- go to Advanced> Fix Permissions
- Reboot system now !
- Enjoy.
***I've used this method for a trillion flashes !***

No need to wipe anything when updating nightlies. Like it was said before, wipe data and reflash when you face problems.

Note to OP: Don't flash Gapps if it is included already in the ROM you installed.

after flash i wipe the cache/dalvik. I think it is the option after you flash in twrp.

Thanks for your answers

I will try that tomorrow.. I hope it erases all my bugs..

One noob question... Full Wipe is Factory Reset?
Edit: Formated Everything except internal storage before install Rom, then.. something strange happened.. my backgroud menu was bugged.. like seeing another menu behind settings menu.. even in twrp i saw the original USB menu of stock..

Not just factory reset. A full wife is made in cwm recovery and it has 3 stages : factory wipe/data,wipe cache partition,wipe dalvik cache, format /system.

A full wipe doesn't mean format /system. If you format system after flashing a rom then there is no rom exists in your phone anymore. Performing a factory reset also clean cache partition too.

if you would've payed attention, he mentioned he made the wipes BEFORE flashing a custom rom. so, yes, it's recommended to perform a /system format.
