Pls help me flash a clean Vanila ROM... - LG Optimus 2x

Hi All
Received my LG 2X today and so far no random reboots or freezes etc except ONE reboot when I tried to install Swype keyboard but that was before I updated to V10D via LG's software update. Hope it stays that way!
Anyway I would like to install a clean Vanila 2.2 or if available a 2.3 ROM but I have never flashed a Android phone before.
I understand I will have to first root my phone which seems easy enough but what do I need to do after that?
And what if I want to go back to the stock LG ROM, is there one availabe or will I have to back it up somehow?
If someone would be please kind enough to provide a step by step guide then I would be most grateful or even just post links to what I need to do/install in the correct order that would be great.
Many thanks.

Hey,
It's actually not that hard .
First root your phone
Do you have an external sd card in your phone?
If so go to the market and download:
Rom manager> when you open rom manager click the flash button
Make sure you allow superuser
When the phone is flashed you can start downloading roms
And put them on the external sd card.
Then reboot into recovery via rom manager or reboot the phone during startup using power + vol down
The recovery menu is pretty straightforward.
Make a backup then do a full wipe, on my first install i wiped every thing in the menu with wipe in front of it
After this click install rom from sd card and then find rom on sd card
If something goed wrong you can go back to your backup, so just give it a try
P.s. Damn thats alot of work on the phone to type
@other ppl please tell me if i forgot something

About the External SD Card, i could not flash any rom from external..
only from internal SD card..

I believe thats not possible, if you click something like inatall zip from sd card it should go to ext card?

Stuck on N1 logo but not bricked

I searched before I posted this question since I know it is a common question but I can't seem to figure out the problem with my phone.
I recently just bought it and I decided to root it. I following the instructions from wiki.cyanogenmod.com/index.php/Full_Update_Guide_-_Nexus_One_Firmware_to_CyanogenMod When I went through the instructions, everything went through smoothly. No errors, all were complete installs but my Nexus One is stuck at the boot screen now. I waited for over 20 minutes but it wouldn't budge at all. I've done the procedure after "fastboot oem unlock" and "Flash CyanogenMod" already but it doesn't seem to make a difference. The flash that I'm currently using is the update-cm-5.0.5.1-N1-signed and gapps-passion-ERE36B-2-signed. Do you have any idea what could be wrong with it or what do you suggest any steps I should take to fixing it?
I don't think my phone is bricked since I'm able to go into Bootloader mode and Recovery.
Try a wipe and if not reflash and re wipe.
Mine is doing this too and i did exactly what OP did
Even after a wipe. Im reflashing right now
5.0.5.2 has just been released. Apparently fixes this bug. get it while it's hot.
Its still taking forever to boot. Im still watching it. What exactly do i do to do a "Wipe"?
Damn I don't have a microSD reader. =\
Is there any way to put the ROM on the microSD via Nexus One?
I'm having the same problem. This is on the recently released ATT compatible N1. I am able to go into Amon_Ra's 1.7 recovery and successfully install the V5.0.5.2 and gapps-passion-EPE54B-signed.zip but still have the same problem. Stuck on the X with the lock. I keep putting the original Rom back and doing it again after a full wipe and still have the same problem.
you dont have your usb cable? I was thinking about that too. Cause i know the nexus has its own memory internally but it doesn't show up under my computer. maybe you can push files through command prompt or something. or on linux
If you have the Amon_Ra's recovery you can do a wipe once you're in recovery.
If you made a backup of the original rom you can just put that back and boot into the original rom. once there, you can mount the usb and download it to the sdcard
you can also download the cyanogen updater from the android market and download the rom to your sdcard to install.
What did the trick for me was fresh install of Cyanogen 5.0.5 which i got to boot succesfully AND THEN use cyanogen updater to get to 5.0.5.2

2 ways, either plug it in via usb and mount it from your notification bar on the phone, or download the rom via the web browser on your phone, then use Astro file browser(free) to move it from downloads to the root folder of your SD card, then flash from recovery.

How long does it usually take to restore? I have about 18 lines of dots. Should it be taking this long?
5.0.5 first then update
Install the base 5.0.5 first then the google add on if you want the apps. After you boot like that update to the latest CM. I saw this some other place and this worked for me, don't wanna take anyone's credit.
Thanks everyone. 5.0.5.2 worked flawlessly once I was able to put it on my microSD.
If you guys don't have a MicroSD Reader, and have the AmonRA recovery, just boot to the recovery and chose I think the 3rd option (Toggle MS USB). You'll be able to see the phone as a mass storage device.

Nexus one repetitive restarts

Hi,
everything was fine until I have performed a restart to my nexus one CM7 and then repetitive restarts started taking place. nothing recent has been done except the regular updates.
I have booted into CWM in order to restore from a previous backup but unfortunately when i enter all the options of the CWM i get a black page with the ROM manager logo.
could you please help me out on how to restore my phone, or at least how to flash a new ROM from zero via ADB or so
Thanks,
There are many ways but you really can't flash a rom easily with ADB. Read the tutorials if you need to learn how to flash a rom. But you should be fine if you just wipe and flash whatever rom you want.
Please look at Nexus One Wiki, section "Unroot/restore", PASSIMG method.

Sounds like a corrupted sd card maybe. Do you have EXT partition? try format the sd card, new sd card or even try booting without an sd card to see what happen.
Had this happened once when i was on CWM, my EXT got corrupted and it was endless bootloop. Format my sd card, use Amon Ra to partition to Ext4 again and all was good.

[Q] Challenging technical issue

I have a problem and i would be very thankful if anyone could help me solve it:
I looked around the guides here and on youtube and found out that installing a custom rom is much better than sticking with the original gingerbread, so that's what i did. I tried RocketRom for a while and decided that i want to try checkrom to see which is better. So i downloaded the rom, performed all the wipes (cache, dalvik and battery stats) and reset the phone to factory. However due to my immense stupidity i forgot to put the rom on the internal phone memory and i saved it on my microsd card instead. so now i'm stuck: I can't access my internal phone memory because my phone won't start (either bootloops or it shows the boot animation once and then a black screen with nothing on it). And i wasn't able to use CWM to flash the rom using my microsd card because it keeps giving me the error "unable to mount". I looked around again and read that i should format the microsd card but nothing changed and i kept getting the same error.
So this is basically it. Is there a way to access the internal phone memory with my phone turned off? If not, what should i do? I just need to paste the damn rom but i couldn't figure out what to do :S
Any suggestions will be very very appreciated, and thank you for your cooperation

Seems like you have issues with CWM as I can access the external sd card without problems..
I think that your only solution is to:
-flash a pre-rooted GB ROM from THIS thread
- Use Chainfire's corresponding kernel to the ROM you flashed so you can get CWM recovery, get it from HERE
- after having both rooted ROM and the CWM recovery transfer the ROM you want to the sd card and flash it from CWM Recovery
Hope this helps
thanks
Thank you for the prompt reply, but i am still quite confused: how can i flash a rom if my phone does it boot? how will i get the rom to the phone memory? Remember the microsd card isn't working so i can't use it for flashing.

Ok which version do you recemmend? and should i use a wipe or non-wipe version?

Help! Meday!! Phone Reboots into cwm

Hi All,
I am in desperate need of help.
I have a nexus s. rooted, with cyanogenmod kernel and slimbean rom.
My friend has a galaxy s1 that had unrooted froyo.
A friend of his rooted it, and put gingerbread on it. I wanted to put slimbean on it for him.
I did so.
Except, that his mobile network wouldnt connect.
I googled, and found that this could be because the kernel is not compatible with the rom.
So I downloaded cyanogenmod kernel and flashed.
But this didnt work, because I think the download was corrupted or something.
I tried to re boot into clockwork, but it just got stock on the first loading screen.
Since then I have tried everything and have been googling for hours... I dont know what to do. I have tried so many different things.
Please can some guru help me figure out what to do?
My friend is pissed as hell at me, I told him it will be painless quick and easy. Thats how it was for me and i assumed same for him.
PLEASE!! I need HELP!! :'(
Edit: I reflashed semaphore and it now goes into cwm. But now when I flash the rom and reboot it, it just reboots automatically into cwm again. Anyone know where to go from here?
Thanks in advance,
Zeddicus

It appears to be a bootloop. That means flashing messed with boot partition and you have to reflash boot. Is this phone i9000 or i9001?
Search for similar topics like: http://forum.xda-developers.com/showthread.php?t=1590747
If you can get to CWM or download mode nothing bad happend - you can repair everything, however it would be wise if you had backup of previous, working ROM
Calm down its fixable first you try to fix it without Odin by
- flashing slim bean again don't forget full wipe flash i9000.zip twice the first time it will reboot half way through at least it did for me
-then pull out the battery and boot into cwm
- flash both slim bean files
- this should get the phone starting again after that to get network working flash this file in cwm http://www.mediafire.com/?fbgxblhbip7bkuv it should get network running credit goes to pwneman for that
Let me know how it goes

Try to format your sdcard in fat32 filesystem (through Windows/CWM or any other various ways if this won't work)
Also try other sdcard...
If formatting card doesn't fix the problem try to reflash CWM via Odin in Download mode.
ok i did a hard reset and left batt out for a good few min and got the sdcard back again.
i followed the steps u said latrop and it didnt fix it... still booted back into cwm...
since i now have the sdcard back i am making a backup zip file of it just in case lol
@divibyzero
i followed that post but it didnt fix the problem
OK you will have to flash with Odin I'll get back to you with instructions

OK follow the in this website and use the new sourceforge mirror http://www.darkyrom.com/index.php?threads/odin-darkyrom-10-2-resurrection-gti9000.4272/
Make sure you have the Samsung drivers installed http://forum.xda-developers.com/showthread.php?t=961959/ then once that's done phone should start up if it does follow my previous instructions

Wait, before you odin flash:
Let me get this straight, your rom .zip is on your external sd card? it has to be in your internal sd card.
From the recovery main menu, go to mounts & storage. From there, plug in your phone to your computer and select "Mount internal USB storage."
You'll be able to then copy the rom file into your internal sd card. While you're at it, I'd recommend X-Bean, as it's currently faster and more stable than SlimBean. Then, unmount your phone and return to the recovery menu and select install zip and choose the file you've just copied.
Please let me know how it goes.
@kngroo
thats what i did.. ive flashed tons of roms and kernels before on my nexus s...
its this galaxy s 1 that isnt working for some reason... it was meant to be a quick and painless proceedure which has turned into a nightmare
gonna probably have to format the sdcard now :*(
Hi All,
I wanna give a SERIOUS thank you to latrop.
This guy is a freaking legend. He just sat with me for almost 2 hours helping me sort out the phone. We did almost everything you can think of and then some... But ultimately it was latrops great experience and knowledge that helped save my ass here...
Phone is running full on slimbean rom with great reception etc.
Latrop... you are a legend!!!
Just wipe/factory reset and wipe cache
its work for me and maybe it would work with you too

[Q] Which SD card do they refer to?

My brother has a Galaxy Ace(As do I) and he was wanting to put a rom on it, so I showed him a few tutorials on xda and helped him through the process. I myself don't have a rom on my phone, but I spent a good half month trying to fix my phone after my friend convinced me to flash a rom designed for the S3...Yeah, bad mistake...
So in all the tutorials they say to just put it on your sd-card and then flash it from recovery and etc. So we tried that and it ended up not working(At least it seemed like it didn't, I know you are supposed to wait 10 or so minutes to see if it gets out of the boot loop, and we waited about 20 mins) so I just reflashed a stock rom using Odin and everything was fine.
But it got me thinking, is there a specific location you should be putting the file on when you flash it? Because it was just on the external SD-Card, not the internal SD-card, is that a problem?
Also, is CWM Recovery required, or is it just to prevent you from needing to reflash a stock rom after you screw up?
Still kind of a noob when it comes to this stuff, thanks in advance =)
Put the file on the root of your external micro SD card, not inside any folder, not in internal memory, just on sd card [ sd/*here* ]......
Some ROM can't be flashed via phones recovery, they do need CWM Recovery + CWM recovery (backing up the data) help you to save your phone's data if anything goes wrong
