Hi everyone, I've been using mik's cm7 for my LG P500. I would like to ask how can i revert back to original LG froyo. I know that upon flashing CM7, a backup using nandbackup should be saved but unfortunately I lost that backup and now its nowhere to be found. Someone help me please.Is it safe to go back to the stock rom?Please teach me or if anyone knows the link on how to do it please tell me...
Please help me oh Gods of androids

Q. How to get back to stock? I need to give my phone to warranty services how do I revert to official LG rom?
A. Check this thread. It is the v10b 2.2 stock rom as a flashable zip package. If you can't access the recovery, then see if the firmware for your country is available here or use this tool. Download the firmware and use the KDZ tool to flash. You will find instructions to use the KDZ tool on this thread. For a picture guide, check this thread.
Also for official GB lovers, see this. It is a v20g rom in flashable zip package. Or if you'd rather flash v20c/g roms from LGMDP, the links for that can be found in this thread.
If you are on the Optimus T, see this post. Uses the KDZ method.
If you are on the Optimus V, see [URL="http://forum.xda-developers.com/showthread.php?t=1025911]here[/URL].

use kdz updater (search xda)
or
use lgmdp (http://forum.xda-developers.com/showthread.php?p=19006040#post19006040)
or
if u like to use indian froyo (http://forum.xda-developers.com/showthread.php?t=1324105)
Many thanks to all of you guys. Another thing, is there any danger in reverting back from cm7 to stock rom? What I want to know is what will actually happen to my phone? will my Sd card be deleted?how about the applications? I have saved cm7 backup using nandbackup..would it still be available once I decided to return to cm7?
Sd card wont be deleted. You can copy your CM7 nand backup to your computer if you want. The nand backup rests on your sd card. Since your sdcard will be untouched, it will still be present after you revert to froyo.
Sorry for being such a nuisance and I know that I've been bugging you guys for a while..But Just one last question though. Currently Im using CM7, but when I try to flash franco's Kernel or Goldenleaf by fserve, I am encountering a very annoying problem.
1. When I lock my phone and try to unlock it by pressing the home or option button to bring out the unlocking screen,my phone seems to hang and stay in black screen where I have to wait approximately 5mins to get rid of the black screen and to gain access to the unlocking screen.
This is really annoying
black screen bug is a non problem and it has been fixed in the new version of goldenleaf and GBS
Thanks a lot..the goldenleaf i initially installed was the 111126 version.changed it to 111205 and i think everything is okay now

hey
so i bought an optimus one this week and have already noticed the touch lag and stuff.
was always gonna root it, and have done jailbreaking on ipt/iphones but i know nothing about the android equivalent apart from what i have googled since then.
have read http://forum.xda-developers.com/showthread.php?t=901247 and a lot of other stuff and i thought i got it, but obviously i didnt.
basically, phone was on 2.2.2 so i downgraded to 10a 2.2 so i could root. ran z4root, installed custom recovery and then flashed milk_os's fixed kernel onto it.
kept showing "android.process.acore has stopped working" errors on screen, and i thought i could just upgrade back to 2.2.2 without breaking the kernel.
couldn't find a download of the latest firmware (but have since then) so i used pc suite 4 to update.
phone is back in 2.2.2 but root is gone and kernel is back how it was before.
tl;dr what i want to know is the difference between a rom and a kernel, and if it is possible to update the OS without changing the kernel, or root on 2.2 and then update to 2.2.2 without removing root so i can then install the milk_os kernel.
i have a copy of the latest update 2.2.2 from my provider which i can install with recovery if it will stop it overwriting kernel and/or removing root.
alternatively, cm7 is a 2.3.3 rom, is it worth just downgrading, rooting and flashing that? i assume that wont break my root
sorry for noobness, i just want to play angry birds without lag and im a compulsive fiddler/breaker.
PS also, if i go to 2.3 gingerbread am i correct in thinking my class2 microsd card will not work anymore on account of app2sd or whatever?
can someone please just tell me the best option for me, i have tried to google and read myself to find an answer but new to the scene and some things seem to be taken as understood and i don't get them at all.
thanks

a. kernal =/= rom
kernel is something that works beneth the operating system.. its like this
YOU -> Interface -> Operating System (ROM/Android/Linux/JVM) -> Kernel -> Hardware
and back.
I also assume LG's updater flashes both the rom and the kernel. so in simple terms, use Custom Rom to flash a new rom (void/CM7/etc) and use it. There is no trick way of the stuff ur explaining to happen.
b. Android 2.2.2 doesn't do jack ****. downgrade to 2.2 then upgrade to CM7 or whatever. class 2 sd cards SHOULD have a random unmount error. i think void might have fixed it; check plz. flashing cm7 should fix everything u explained, but don't expect much from the ROM; its in dev. FYI touchscreen fix is included in cm7
c. custom roms, including cm7 has root built in.
d. conclusion
i. use cm7 route -> flash custom recovery -> flash CM7 (tricky, be careful) -> touchscreen profit!
ii. use froyo rom route -> flash custom recovery -> flash rom of ur choice (void, megatron) -> flash touchscreen kernel -> reboot -> profit
e. press thanks if ur thankful. i would like some thanks lulz
cheers
There is a Kernel you can flash that helps fix the bug
http://forum.xda-developers.com/showthread.php?t=929941
thanks!!!
awesome, thanks heaps for that.
just one more thing, i assume the custom roms like cm7 and megatron/void all have root built in? or does the custom recovery do something to stop the root being removed when you reflash
once you root the phone, no matter what custom rom you use, it will still be "un-rooted".
Only when you use the kdz updater to put back original firmware, phone is no longer rooted.
thanks
awesome, thanks for that
Hello Everyone
I Have A An LG P509 And I Was Wondering If There Was A Rom With Swype Availible For This Phone Thats A Gingerbread Rom.
Also I Was Wondering If I Want To Unroot Later Will The Recovery Rom Have To Be The Same Firmware? For Ex (The Recovery Has To Be 2.3 If I Rooted It To That) And How Is It Possible For The Phone To Be Back To Its Original State When Unrooted?
I KNow I Asked 3 Questions (So Sorry For That) But These Things Been Rolling Around My Head For A While. If You Do Help I Thank You Greatly
1.no, u can get swype for free. Google for swype beta.
2.yes
3.yes unless u installed custom recovery.
Unrooting is not the same as flashing an original recovery firmware. I have not done this so this is just my imagination.
There are some posts for the original P509 recovery if you wanted to flash the LG firmware to return the phone to the original. You can also save the original recovery firmware before flashing a custom recovery. That uses the "dd" command to make an img file. I should have done that first. Look in the posts to find that exact command.
Unrooting is mostly just removing the Superuser app and "su" command and doesn't require reflashing, I imagine.
I don't know about the Swype for gingerbread.
Thanks For For The Help Guys But If It Has To Be The Same 2.3 (Gingerbread) Rom How Can I Return The Phone Back To The Original State When The Original State Is 2.2 (Froyo) Is There a rom i dont know about?

You will make a NAND backup before installing the new ROM. If you want to go back -> Restore backup.
Or you cand use KDZ update; it will install a fresh new factory ROM, your phone will be just like when you unboxed it.
try http://www.filecrop.com/
I wanted to change the kernel from my P500 to solve the lag problem and get better overall performance.
I rooted the phone using gingerbreak 1.20
after that i installed from the market Rom manager restarted the phone, and i backup the phone from there.
After that I got stuck with my kernel replacement and I gave up and I wanted to reset the phone to default state. I didn't do anything to my phone.
I unrooted the phone and did the factory data reset.
Now when I reboot the phone and press power+volume down+home I still get the Clockworkmod Recovery boot menu. In an untouched P500 what do you get when pressing that combination? Is there any way to make my phone 100% factory state ?
sorry for my bad english
u should even delete the recovery.....(TO get rid of it)
the recovery is on the sd card, right? i formated the sd card... so there is nothing related to rom manager...
u must try flashing the default rom from the devlopment forum.(KDZ Updater)
blah
if i wait for gingerbread update will the update solve this?
The Recovery is not on the sdcard.
Go here:
http://forum.xda-developers.com/showthread.php?t=1065197
and download the file "Original_Recovery_thunderg.zip" (or something to that effect) and flash it through cwm. This will restore the recovery as it was originally.
The zip is unsigned so you will have to toggle signature verification in cwm recovery.
@mihir he doen't want to get his recovery back(in other word he wants to remove it).
@soberspine http://forum.xda-developers.com/showthread.php?t=944881 check dis thread and install the original rom...
@devil the original recovery zip in the link will restore the condition of the recovery to factory condition, i.e remove it.
this android reminds me of installing windows 95
the new unpdate to gingerbread will come out next month, so the update to 2.3 will get rid of that boot menu and other things that where changed when I installed Rom manager? in other words will the phone go to factory state before rooting/unrooting and stuff.
Yeah most probably the recovery will be cleared if and when you update to gb. But if you want to clear it now use the zip, it works.
Sent from my LG Optimus One P500 using XDA App
I don't think you'll be able to update to GB from a custom ROM or rooted phone. Even if the option comes up, it is recommended to go back to stock state (without recovery and root) or else it might cause problems.
i didn't installed any custom rom. the only thing I did was to root my phone using gingerbreak and then installed rom manager.
the only thing that changed to my phone is that now it has that boot menu clockworkmod.
now i unrooted my phone.
So it is not safe to make official update even if the only change is that i have on my phone clockworkmode?
Step by step picture guide to completely restore to open-box state using KDZ updater
did this for thousands of times and if you are doubted in any steps feel free to ask me
btw for your question, an un-touched optimus one pressing the recovery combination will result in
a stable image of an android jumped out of a white-rectangular box
a bar at the bottom loading
but that's it, nothing more no matter how long you wait
Also for your updating question:
LG WONT recognize your phone with their official updating tool only when you are ROOTED (so of course when you perform any other steps after rooting, it wont either... e.g. installing custom recovery, flash roms etc)
BUT if you go back to the original thing with KDZ, LG will update anything for you -tested by myself!
thank you for all the clarifications and the tutorial.
I will wait now for the new android 2.3 release and ill do the whole thing then.
It is possible after rooting and installing clockworkmod the phone to work slower?
It feels like the phone is responding slower or maybe is just me imagining things .
hehe. nothing like that.

Hi Comm
I am new to SG-A and Android itself. As far as i can say from using this phone for one month now is:
- It is fast (i don't play games)
- It is practical
- It is just VERY NICE
BUT, there are some negative aspects also:
- Battery runs out very fast (1 - 1,5 days) - WLAN/BT/GPS/GP3/2 are switched on manually only when needed.
- Low internal memory (278 MB)?
So, what do i want to do next?
- I would like to improve Battery life duration, and i hear that other ROMs do safe battery life duration.
- I would like to delete all the Samsung Apps and stuff from the phone
Note: I have tried out an app called "juice defender", but i am far from enthusiastic about it - it switches on and off the 3G network automatically what is very practical, but hangs itself up occasionally.
What have i learned on xda-developers.com yet?
- There are instructions on how to root your mobile, to have admin-privileges
- There are instructions on how to update firmware
- There are different ROM's you can use (like Cyanogen and GingerReal)
And - that there is no BEST ROM, only different ROMs for differents tastes.
What would i like to know from you now?
- Is it for real that other ROMs enhance battery life? (more than like 100%?)
- Would you agree to kick out all Samsung apps? Also to free up some internal memory.
- What ROM would you recommend me? As mentioned, i don't play games. I just need a practical and fast operating system on my phone. I make phone calls, write sms, and occasionally look up information on the Internet Browser. And i would like to enhance battery life somehow.
That Cyanogen ROM sounds promising, but ain't ready to use yet?
Others wrote that the GingerReal ROM is the most used one here for SG-A, so can't be a big mistake to give it a try?
Thank you so much for your recommendations!

Yup. Gingerreal is the most stable. Cyanogenmod roms are still beta so for a new user you may wanna explorer stock based roms and mess with Odin and clockworkmod before going into beta roms. Of course, it's personal preference.
Everything is pretty simple. For Gingerreal, just get a 2.3 update, then get clockworkmod, then flash the rom. Follow instructions in the development threads to the letter, you'll be safe and happy.
I have been using the official 2.3.4 rom with CF-Root, and Link2SD to account for the lack of space, and it works amazingly fast.

In the GingerReal thread there is a link to another thread which has the clockworkmod recovery. download it, power off, boot into stock recovery by holding home while powering up, then install the zip you downloaded. You get clockworkmod then.
You don't need root. After clockworkmod, download the GingerReal zip and install from sd card.
If you wanna use darktremor app2sd then partition your sd card. Google for that.

The point is to have GingerBread bootloader~ it's tested on that firmware so its good if you flash it~ just to avoid problems~

No don't flash it while on an another firmware,flash the firmware to the version stated or you might end up with a bricked galaxy ace.As stated it has been tested on those firmwares and its safe..

Hello,
I have had my T-mobile LG P509 Optimus T for about a year now and I have had it rooted just as long. My husband plugged it into his PS3 the other day and it went to the fastboot mode started screen, thanks to the wonderful posts on here I was able to fix it. Then the following day it got left outside all day long, battery was drained and the phone was off. I charged the phone and when I turned it back on it would not go past the Android Logo screen. Again thanks to all the wonderful posts on here I was able to get it back up and running. The problem I am having now is that every time the phone gets turned off, it gets stuck on the android logo screen again and I have to re install the ROM. the recovery is not helping. It is quite tedious to have to constantly re install everything from Google Play just to get my phone to work. Is there anyone out there that can give me a permanent fix or give me a ROM that is specific for the LG P509 instead of the one I am using currently that is for the LG P500 Optimus One.
Android Version 2.2.2
Kernel Version 2.6.32.9
Build Number NuDroid T1D-S
Software Version LG-P509 V10s
Recovery Rom is Original_Recovery_ThunderG.zip
ROM is FRG83.zip
p509
the roms are the same
my phone is a p509 but im running every rom on this forum fine and everything goes well except some cases of data because tmobile uses a "funny sim"
P509
I figured they were. I am just trying to find out why every time my turns off and I turn it back on I get stuck on the Android screen and it goes no where, Doing the recovery of my back up from the recovery menu (volup+home+power) does nothing I mean I actually have to re install the ROM. Is there anyway for me to find out what is wrong. What ROMS are you running if you do not mind me asking. Also is there an actual list anywhere of the Factory System Apps that I can freeze with my Titanium Backup. I have the Pro version. PLEASE HELP. I have had this rooted for over a year with no problems and now it just wants to act all crazy.

It sounds like the rom is corrupted. I believe from your description it fails to load properly on reboot. there are a lot of options available for you. Most of the roms are for new baseband. Unfortunately you will have to experiment. Read the posts carefully, start here first http://forum.xda-developers.com/showthread.php?t=1152306. Next I would read this http://forum.xda-developers.com/showthread.php?t=901247 this will tell you almost everything you want to know. I would upgrade to the new baseband v20g http://forum.xda-developers.com/showthread.php?t=1149530 . Then I would upgrade the rom there are many good roms available. I wish you luck when I first stated flashing roms there were three days of hell before I started to get amazing results. I have a P509 on t-mobil network, and currently running cyanogem mod rom 7.2.0 RC1 it is gingerbread 2.3.7 New basband with lots of script tweaks. the performance is very good. good luck I will check back to see if I can help.

Thank you,
I will give those a look and see what happens. I will let you know.

i have same problem i have p509 and my phone fell during kdz and i think it partly works but no rom can load up :O
P509
I have done many different options. The one that I found to be the easiest is to take your micro sd card and put it in the adapter into your PC. Then in the ROMs section of this forum find a ROM that suits you. or you can use the Rom I listed in my initial post being the FRG83.zip download it to your PC then copy it to your SD card. Put your SD card back into your phone. Then go to the recovery menu. Volup+home+power hold until the recovery menu pops up. then wipe the data, then install zip from sd card choose the file that you just downloaded and let it do its thing. It has worked for me numerous times. All else fails follow the guide that is posted above very good info to have.
