[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.

[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.

[Q] Custom Roms / Kernel Questions

I have a AT&T Samsung Galaxy S3 (SGH-1747) that is running stock with root.
I have rooted my phone using the samsung toolkit located here: http://forum.xda-developers.com/showthread.php?t=1746665
Since that toolkit flashed a CWM Based recovery I have installed ROM Manager and flashed CWM Recovery version 6.0.1.2
My questions are..
- with my current setup.. am I technically running the "Stock" samsung kernel?
- why would you want to flash a different kernel to your phone?
- and is it necessary to flash a different kernel in order to use certain custom roms?
- At first I was leaning towards flashing CM10 nightly but the more I look at it.. I want to flash PARANOIDANDROID 2.22 http://forum.xda-developers.com/showthread.php?t=1818199
Is this rom fully compatible with my AT&T phone? and since i'm running stock with root, do I need to do anything special before flashing this rom? Factory reset? Wipe Data? I've already made a full nandroid backup.
Thank you!

- with my current setup.. am I technically running the "Stock" samsung kernel? I believe so
- why would you want to flash a different kernel to your phone? Different kernels do different things.. some have better batter life.. some let you OC and UC..
- and is it necessary to flash a different kernel in order to use certain custom roms?Well sometimes.. Well technically.. most kernels will work with most of the ROMS out there.. as long as you stay withing your phones threads.. But some ROMs have a kernal with them.. and some ROMS you need to flash your own kernel..

Thank you for the reply.
On the rom i'm wanting to flash for my SGH-i747 http://forum.xda-developers.com/showthread.php?t=1818199
The steps for flashing are as follows:
CWM: Install Zip: Rom: Download Here Make sure the file you download is PA-2.22-d2att.zip
CWM: Install Zip: Gapps: Download (These are the new ones)
CWM: Wipe Data/Factory Reset
CWM: Advanced/Wipe Dalvik Cache
Reboot and edit your Apps Dpi & Layout under Settings/Paranoid Settings - DO NOT RESTORE YOUR OLD PROPERTIES FOR NOW
Would i need to wipe data, factory reset, then also wipe dalvik cache BEFORE I install the rom and gapps since i'm running stock with root?
Thank you

i'm also reading that for paranoidandroid you must first flash CM10 then flash paranoid.. is this accurate?

umm.. not sure where you saw that you need to flash a CM rom before flashing the paranoid ROM..
I believe the Paranoid rom is based off CM
The instruction on the link you have, in my opinion, is wrong..
The way that i flash my roms is...
Wipe data/factory reset..
Wipe Cache
Wipe Dalvik
Format/Data
Fomat/System ( i think deletes backups) only do in emergency.aka optional step
Flash ROM
Flash Gapps.
THATS IT
Some people will wipe cache afer flashing a rom..
But if you wipe data/factory reset i believe deletes the ROM...

If you are already running CM10 then you don't need to wipe Cache. Just dalvik and data. Im pretty sure thats what was confusing, since this is based off of CM10.

yeah, I just keep reading and reading.. probably making this out to be more difficult than it really is just don't want to end up with a brick or anything.
I'm already on stock + root + latest CWM so I just need to put the files on my phone and flash but I believe these are the steps i need to take:
1- Download ROM and Gapps to internal sd card
2- Boot phone into recovery
3- WIPE Cache/Delvik/Data factory reset> Mounts and Storage- format system
4- Flash ROM and Gapps

Dirty flash

sorry for the noob question what is dirty flash

Flashing a rom without wiping /data first. A "filthy" flash would be to flash without wiping even cache and Dalvik
You can dirty flash between minor version updates of the same rom. Whenever you flash a major update (let's say from bestromever JB 4.3 based to bestromever JB 4.4 based) or if you flash a rom from a different developer you need a clean flash, meaning you need to wipe data, cache and Dalvik in your custom recovery.
If in doubt: clean flash

Custom rom + Custom Kernel = Black screen..

Hi,
When i tried flashing a custom rom and a custom kernel it just gives me black screen after starting up again maybe you guys have got the same problem before and what did you do to solve this issue? I tried these custom rom/custom kernel combinations :
FreedomOS-op3-nevax-1.7-CE-signed / blu_spark_r114-OOS-6.0.1 thulium
FreedomOS-op3-nevax-1.7-CE-signed / ElementalX-OP3-0.23
ResurrectionRemix-M-v5.7.2-20160804-oneplus3 / blu_spark_r114-OOS-6.0.1_thulium_e476ded
ResurrectionRemix-M-v5.7.2-20160804-oneplus3 / ElementalX-OP3-0.23
My TWRP version is 3.2.1 official
These are one of the many methods i tried:
Method 1
1. Wipe Cache, Data, Internal storage, Dalvik/art cache and system.
2. Flash Custom Rom.
3. Wipe cache, Dalvik/art cache.
4. Flash Custom Kernel.
5. Reboot.
Method 2
1. Wipe Cache, Data, Internal storage, Dalvik/art cache and system.
2. Flash Custom Rom.
3. Flash Custom Kernel.
4. Wipe cache, Dalvik/art cache.
Method 3
1. Wipe Cache, Data, Internal storage, Dalvik/art cache and system.
2. Flash Custom Rom.
3. Flash Custom Kernel.
These are some of the combinations i tried and even some of the methods i tried are nonsens but i am just trying to get it to work. If you need any more information just tell me . Help is very much appreciated .

3.5.2 base dont work with custom kernel yet. The twrp Version is a non known at my End. I think you better read this forum. From A to Z. Since all your awnsers can be found easy.

3.5.2 base? Can you please explain it a little bit more detailed thank you and i already read alot and can't find it thats why i made a thread.

Please read the freedom os topic. It address well why you cannot Flash a custom kernel. It is simply that kernel sources for Version 1.7 (aka 3.5.2 base) are not releases.

As suggested earlier try reading some ROM threads, going around flashing ROMs and kernels with no purpose is going to get you a soft brick very quickly.
My suggestion decide what you need out of a ROM, that is missing from stock, read a few rom threads to identify one that fills your needs. Then when you've got a ROM in mind go back and read the thread THOROUGHLY before flashing, had you done this with FreedomOS you wouldn't be here now.
