[Q] Boot loops and freezing installing kernals - LG Optimus 2x

I am trying to update my kernal. After installing various zip packages my phone will enter into a boot loop, return a black screen after the first LG logo or freeze during the animated boot logo.
I have tried all different versions of ironkrnl and Vadonka's kernals.
I'm running a clean install of Temaseks CM7 KANG 33 and using clockworkmod recovery version 5.0.2.7-RC2 for internal memory card.
Am I missing a vital step? What is the correct sequence to install a new kernal?
Thanks.

Check the installation guide in those threads....should be some wipe which is missed....Dalvik wipe (inside the Advanced menu in CWM recovery mode)usually the reason.
if you have the connection issues....check the BB and RIL combo....CM7 is with 218BB and check for the relevant RIL

I've tried again wiping the Dalvik cache as you suggested. I received a notification that there was no sd-ext path.
Now the phone hangs at the second LG logo each time. I checked through the kernal threads and there are no specific instructions other than installing from the zip files via CWM recovery.
Vadonka's script includes a cache wipe.
I'm stuck for ideas.

Strange... This problem occurred to me too, but after I used Temasek's P204-28 KANG the problem disappeared. So you might want to try that

EXT 3 or 4 partitions?or re-flash the ROM once again with wipes and then power off instead of reboot....then after a while retart and see....

So it usually happens to me when I install a rom and immediately the kernel; before it, you must reboot. Another possibility is that you have the wrong file system or the kernel is not supported by your ROM

I tried with CM7 204-28. It went into another boot loop, however the system did start up completely. Then it would randomly reboot every 30s to a minute.
Tried rebooting after a fresh install of CM7 (performed a factory reset/wipe). Then installing the kernal later ... froze at the second LG logo again.
As far as I am aware both the ironkrnl and Vadonka's kernal support CM7.
I'll contact them to make sure. Thanks for the help so far on this.

[Q]Stuck on ROM [SOLVED]

kefmaster said:
I fixed it!
I tried installing the older 3xxx CWM from rom manager, and then tried installing the rom but still didn't work. So I just reinstalled the 4.0.0.5 and wiped/flashed EXT3 and everything and now works :S
I don't know if this was some bug, but I got it fixed by just reinstalling CWM. Also the wiping takes a little longer than normal.

I've been flashing ROM's since I got my G1 two years ago, but never had anything like this.
I'm stuck on the Blazingdragon 1.8b ROM, I can only flash that ROM and boot. If I try any other ROM my phone freezes at the LG logo with the loading bar. Even updating to Blazingdragon 1.9b freezes my phone, I tried converting to EXT4 and back but wouldn't help.
Anyone know what to do?
Info:
Recovery: CWM 4.0.0.5
Baseband: 622
Current ROM: Blazingdragon 1.8b
BlazingDragon 1.9b uses EXT3, so you will need to convert to that before installing it, otherwise you'll be stuck on boot.
Use this to convert to EXT3 - http://imperticus.com/android/r1-backtoext3-2x-unsigned.zip
I flashed the back to EXT3 zip and then the Blazingdragon 1.9b, but I'm still stuck on boot.
How long does it normally take to flash the back to EXT3 zip, because mine is done in seconds, is this normal?
If all else fails: Backup, nvflash, root, download cwm, flash it, flash new rom, recover backup

If you're using latest recovery 4.0.0.5, always go to mount and storage in recovery and ensure that system, data, cache all those are always mounted before and after u flash something.

What I did:
Mount all the partitions

Flash back to EXT3

Flash RIL622

Still stuck on the bootloop, did I go something wrong?

[Q] Help flashing SwiftExtreme Kernel

Hello.
I´m currently running CM7.1, and I wanted to flash the newest swiftextreme kernel for CM, but I get a black screen after the lg logo. I´m not sure if I´m doing it properly. Do I need to wipe cache or dalvik-cache in orded to do it, or both? and also, if i need to wipe something, should I do it after or before I flash the kernel?
Any suggestions?
Thanks in advance

No as it is kernel it doesn't concern system partition, except for writing some files for example in init.d folder. Perhaps the dev forgot to put the info line.

the latest version for CM 7.1 stable support is 05112011, above that version is not CM 7.1 stable version
Thanks everyone. I tried everything, and that´s right, i don´t think Cn7.1 stable supports the latest swiftextreme. I´m now on Miui android 1.11.18, it runs very well.Battery life is very good.

Problem to install ICSSGS RC 4.1

I try to install but don't work... after that i flash it, the phone lock to logo screen "google" and i can't go to CWM i must use odin to reflash. If install rc3.1 it's all ok.
Where is the problem?
Thanks.
Did you try looking at the help page on the thread in the development section? It's right before the post is finished, there will be a link that will lead you there.
Hope that helps, if not I can try to just copy and paste the instructions hahaha

Ensure you have backed up your EFS directory; if you don't know how ask.
To be honest, there appears to be some inconsistency in the reliability of the 4.1 RC release (across handsets); I have had persistent WIFI issues and then when the wifi fix was released I found the phone to just be a little laggy.
My advice if RC 3.1 works well for you is to keep it on there for now and wait for the next release they make.
However, if you still wish to flash it, there is no 100% working way - just keep factory reset, dalvik wipe, cache wipe, reset until it starts working! That's what I did as the original instructions did not work for me.

I agree with you... RC3 was fine for me... fast and all worked... RC4 has some wifi issues... It switch on/off and doesnt stop till i reboot the phone... im thinking about to downgrade to RC3.1 and wait till the next release...

If i flash 2 time the rom the phone stuck it and i can't enter in cmw
.. is the only rom that give me this problem... bha...
Hello, have you tried to download the rom again? Maybe it's a bad download..
That's odd, for me i got stats 7 but was because i was flashing the I9000B version and my phone was with the CWM for I9000. Try using odin and flash a sotck rom, after that install the CWM and then the RC4.1.
If anyone want to know the procedure that i do to install the RC4.1 is this:
Starting for CM7 --> flash the ARO 2.3.3 rom to re-write the bootloader (check this option in odin) --> flash the ZTO 2.2 rom to re-partition in original size partitions --> flash the 2.2.1 ARO because it's a nice rom and don't have all the trash that is present in ZTO version --> through kies flahs the ARO 2.3.3 original.
After that the procedure to install the RC4.1 is the standard: flash CWM then install the ROM.
I had problems going from 3.1 to 4.1. Same issue as OP.
Process I followed:
-Flashed CWM through heimdall
-Flashed devil kernel
-Flashed CM7 (had to do this twice in a row)
-Flashed ICSSGS 3.1
-Flashed 4.1 but before I rebooted my phone, I flashed Devil one last time.
Since then, phone has been rocking along just fine!

Yes... three times.
I'm having the same problem here.
I tried the first point on the Common Issues page but I'm still not able to go into CWM!
I flashed the Speemod Kernel using heimdll but I can't go back to CM7. I'm getting a Stat 7 error.
Also tried the Devils kernel (Devil_1.0_CFS) with no help ....
Any ideas?
Just wondering...

why on earth did you flash the CM7 as a part of the process? I always have just downloaded an appropriate kernel (devil, stockplus etc..) + ICS ROM (latest was RC4.1), once I'd rooted my stock 2.3.6 ROM with CF-Root (takes only 5 minutes). ICSSGS' ROMs can be applied straight on top of any previous ROM, the only requirement is that you have root privileges + CWM installed. Flashing CM7 is often frustrating, at least for me. I personally see no point in flashing it before the ICS ROM. If you know better, pleasy enlighten me

[Newbie needs help 2] I Just installed temasek's KANG build

I'm new here and the first ROM I've tried installing was RC1 91 but after I finished the procedure, my phone doesn´t leave LG home screen and rebooting after 5 sec. What did I do wrong?
Steps:
- Root;
- Download the ROM;
- Copy in external memory;
- Power off the phone;
- Boot in recovery;
- Backup current ROM;
- Wipe cache partition and wipe data/factory reset;
- Wipe dalvik cache
- Finally, flash ROM and reboot.
And the restore isn´t work too.
Do you have p990 or p999?
Sent from my Optimus 2X using XDA
P990 and i was running 2.3.4 V20l Euro Open
What recovery version do you have?, the CWM "touch" version HAS issues with flashing, try an older version , non touch, also its a lot better flashing from the external SD card than the internal memory (a.k.a. internal SD). (I use 5.0.2.7, you can grab it at Temasek thread, second post)
I had flashing issues and here is how they are throubleshoted:
1: Reflash, sometimes CWM (recovery) make bad flashes, reflash, sometimes it work.
2: Format everything, choose factory reset, then flash again, no need to wipe cache or dalvik because everything is wiped except recovery.
3: Use a script to get partition back to ext3, when a rom uses ext4 it automatically changes it BUT when you install a ext3 rom it does NOT reformat back to ext3, it leaves it in ext4 and thus doesnt work.
4: Try another rom, an older or a different rom, I had this issue with topogigi rom once and the modaco rom its 100% incompatible with my phone... dont ask why no one knows.
5: Use a different CMW version, this is no. 5 if you have a non touch version (mine for ej. has modded menus) but if you have the touch version it has issues with flashing, temasek had problems with his own roms...

you're missing one thing you should format/data factory reset first. of course the restore doesn't work because CM7 converts yours system to ext4. while stock rom the system is ext3.
you should try this script
Code:
http://etana.donka.hu/?dir=scripts
if you like you should full wipe or use nvflash recovery there is a thread there in development thread or from this one
Code:
http://android.modaco.com/topic/335474-25-mar-nvflash-stock-rom-release-v10b-dated-1300166062-15032011/
.
the difference between that script and nvflash is the method. vadonka scripts use CWM. and nvflash use the driver for your computer, if you use method nvflash you have already rom v10b.
after you already use nvflash / full wipe in vadonka script, you can flash cm7 again.
or if you like you can search in development section there is convert to ext3 back of course this method is delete your whole partition
Code:
http://forum.xda-developers.com/showthread.php?t=1021549
did you backup your apps first like using titanium backup??
or maybe this method you can use recovery with nvflash but i think with this method you should have your boot.img backup first i haven't tried this method

Before I used CM10 i just used the stock (flashed latest GB) that came with my phone. So I flashed CWM5 and cleared all the three stuff I was supposed to. I installed the CM10 zip and since then its been stuck on the boot animation, not even a loop. Just the animation.
Any ideas whats wrong?

Well happened with me once when I had put AOKP ROM in my Galaxy Note.
Here is what I did:
Go to Recovery.
Wipe Cache.
Try reboot
No results?
Recovery again.
WIpe Dalvik Cache Also
Try reboot.
Still no results?
Try to wipe data/fac reset and re flash some other ROM as of now (which you are confident about that it will work)
Now go ahead and let the old ROM boot. (Surely it will, as you would have used prior)
Now, go connect USB and check MD5 of the file you had kept on SD Card (I mean the CM10 file)
I found that my MD5 didnt match.
If you think it didnt match download again.
If you know it matches then go for reflash.
But this time before flashing the new ROM just use some cleaning script such as Ultimate KErnel Cleaning Script. In Galaxy Note I used Jbroid Kernel Script. I aint sure now if you can use Jbroid in Ace.
Goof luck!
Press Thanks
I got it working, what I had to do was flash CM7, then CM9 then CM10 :/ after that it was fine Thanks for the help
Welcome
The problem was with the kernel being different in CM10 and official version.
