Can I reinstall original recovery on LG Optimus P500? I didn't make backup, only nandroid backup with custom recovery
Sorry for my english, my native language is spanish
Theoretically it's possible to reinstall via adb or the terminal, but flashing recoveries is dangerous. Most people just advise you to reinstall via KDZ Updater, which installs everything to stock.
Why do you want the original recovery anyway? It just restores factory originals and stuff It's not really that useful, unless you're taking your phone to a service center.
I'm taking my phone to a service center. I can't fin the KDZ for my carrier (movistar - telefonica, Chile).
When I install the custom recovery the cellphone lose the warranty?
I don't know how to undo the installation of the custom recovery via the terminal or adb since I lost the old one.

Most likely. There's a list of original firmware downloads on the Development forum. Check there, but be extremely careful.
EDIT: Wasn't in the list. Try doing the stuff here: http://forum.xda-developers.com/showthread.php?t=865479

Few question
What is the difference between flashing from zip / restoring a nand backup / using kdz.
I have gone through all the posts and have taken a Nand backup after flashing the custom recovery. However this part am still confused about.
I know I need to use the kdz if I need to change the firmware ( 10b to 10c) and also there are cases of people bricking their device by using the kdz updater.
I know that I can upgrade to a different ROM by flashing the zip provided as part of the custom ROMs, however can I do a Nand restore of my original backup ? Would it matter if the version is different eg 10b of my backup and probably a 10e of the custom ROM ?
If the Nand backup restore / zip is much more stable then why are people still using the kdz to change the version.
Any answers would be really appreciated.
I have a question too: How do you restore nandroid backup from ADB ?

Flashing from ZIP is done in custom recovery, usually done for a fresh install of new ROMs.
Restoring a nand backup...I'm not sure if this is "nand" back up...but in custom recovery menu, you can create a backup image of your current phone/rom. I guess it's kind of like a restore point where u can go back to if **** hits the fan.
KDZ Updater, I believe is a tool where you can flash/install "official" roms. At least from what I know of LG Optimus One, official ROM packages are in .kdz package. Where as for example, for HTC, official ROM packages are know as "RUU" installers.
I think if you stick to your carrier's official KDZ ROM packages, there are minimal chance of bricking your phone. I was lucky to install one of Australian KDZ on my Telus Optimus One and got away with it.
You can do a (nand) restore of your original back up. To do this, root your phone, flash the Custom Recovery (follow one of the stickied posts in this thread), and create a backup. When you restore, your ROM version will be whatever the backup ROM version is. So if you backed up v10b, and you update to v10e, and then you restore your back up, you'll revert to v10b.
As I mentioned above, I think KDZ are for flashing official ROMs. It's the tool that LG uses I believe, so probably that's why all their official ROMs are in KDZ. People are using KDZ to downgrade/switch ROM versions because some of ROM versions, such as v10e, can't be rooted using conventional tools.
So which is the command for nandroid restore in ADB ? Thank you.
Nand restore/backup is not ADB tool. You have to boot into recovery mode (if you have custom recovery, just turn off phone, press volume down+home and keep preset power on button. Hold volume spek+home till custom recovery menu didn't appeare.)
Warning: If you will not have installed custom recovery properly, you will do only hard reset!!

nanddroid backup (i think can be restored using nandwrite linux utility try sudo apt-get install mtd-utils) ..NAndroid is more Like(HArd Drive Cloning) whereas FLashINg USING KDZ is like upgrading Your PC's BIOS system...U know what i mean ??? U screw up FlASHING phone is dead until fixed by the manufacturer..HOwever for same model i cud use my friends nandroid backup on my phone..Its like CLONING a OS
If using NANDroid restore from ADB you should navigate to the folder of your backup and run "nandroid-mobile.sh restore". The rest is explained above.
And by the way, sarfaraz1989, the only way to brick your Optimus One is to delete all the "/" directory, as even if you mess up the kernel, you can enter "Emergency Mode" and restore from a KDZ file. Second - NANDroid creates a binary image of the "system", "data", "boot", "cache", and optionally ".android-secure" directories. Third - flashing ROM updates is not the same as flashing a KDZ file - KDZ is LG's restoration archive containing the original ROM, recovery, kernel, etc... and most ROM updates contain updates to one or several system directories.
@Ianis DOesn't FLASHING rewrite the EEPROM chip on the phone??? Doesn't it repartition the ROm into boot,system,cache etc...??? And does't cloning (Dd) create "binary images" What imeant by FLASHING was using the KDZ file only... u missunderstood the post or mayb i didnt put it correctly
it's weird... i'm successfully backup (indeed four kind of nand back up available @ recovery) my source for backup was void#echo + latest fixed multitouch kernel, it just work beautiful before.
Some issue that require flash back to origin 2.2 rom using KDZ, then root + install recovery but any kind of restore still return LG LOGO and hang. (all 4 kind of backup same result)... already clear /davik-cache + /cache even try to clear /data and /ext as well but still the LG logo.
P/S: i'm using Recovery version 1.2. and my card already partition as 0 for swap + 512MB for ext4 that working beautiful @ void rom before.
Any solution? I can redo all the step by step for reaching the same VOID rom but without restore fully function like that... it waste lot of time for "boring HOME WORK"
Many Thanks and Best Regards
I think you have to flash the raw rom again.
Hello! I bought the Optimus One in a telecomunications operator's shop (Movistar). In the first splash the LG logo appears (I don't want to remove it), and then, in the second splash, you can see Movistar logo. The second splash is the one that I want to remove. How can I do that?
You need to use a custom rom, e.g. Prime or Void, those are the two main ROM's for the p500, they both have custom spash screens.
So, I have to install custom recovery, and then flash my phone with a custom rom?
Can it brick my device?

Read about http://forum.xda-developers.com/showthread.php?t=900905
If you want to be fully involved in modding, tweaking your phone, then best way is to:
1.Root with z4root,
2.Install custom recovery,
3.Install any good rom.
By doing above you will have full control of your device, you will learn a lot of new things and can apply them on your phone.
But if you simply want a new boot animation, you can do this:
1.Root via z4root,
2,Install absolute system root application from market or other sources,
3.from absolute system root application you can change your boot animation.
I used Absolute System Root Tools, but it changed the android animation, not Movistar's splash.
Or if you don't want to install a custom rom, you can flash an Original LG Firmware.
You can get the firmware following this instructions

And here is how to flash it to the phone.

I too had the Movistar logo and after flashing an unbranded firmware i got a simple android logo.
Just make sure you read and understand all the instructions befor proceeding.
Cheers
I flashed the phone with some unbranded firmware and it works perfect.
And can you install the original firmware even if you bought the phone in an operator's shop?
I just wanted to flash a custom ROM, I have read and googled a lot but I couldn't find anywhere, how to backup the original recovery, so that if the phone needs to be repaired under warranty, the phone would look completely stock if they try out a factory reset.
So, is there any way to backup the original recovery?
1. How to install nandroid backup?
2. Can i install it in my phone xperia min st15i rooted ics .587 (locked BL)?
3. where can i download the latest official/working nandroid backup for my xperia min st15i?
4. If Im installing custom ROM's and failed, and having boot loop problems.. Can i use nandroid backup to restore where I saved? that means from all files settings? will be back to what state you saved?
5. And If I successfuly installed and boot new ROM, then after many restart/reboot or after tomorrow, can I still use nandroid backup to restore to its previes ROM/OS? without having any problem? Is that how nandroid backup work?
Please answer THANKS!
1.)Nandroid backup is Total Disk Image(think dd command) of the partitions of a phone .This may or may not include ,/system,/data,/cache,/sd-ext,android-secure,kernel and recovery depending on the recovery and phone ...
2-3.)Nandroid Backup is created by the user and should not be shared amongst each other for security and privacy reasons ...So basically they are hard to find and probably it's not a good idea to flash one to your phone...
4-5.)Basically you create the Nandroid backup of your phone from the recovery ...Then you can install a custom ROM ...If you have a problem then you can restore the original backup
So there is no "install" as such of a nandroid backup ....It's Backup from your phone via recovery and restore to your phone via recovery ....
A point to ponder is that the recovery for the Locked BL lies in /system ...If the Custom ROM doesnt flash the recovery to /system properly then in case of a boot loop ,you have to go for Downgrade-Upgrade Root-Recovery-Backup cycle ...
This is relevant to you...
Fastboot, Custom ROMS & ClockworkMod Recovery:
A custom ROM is a fully standalone version of the OS, including the kernel (which makes everything run), apps, services, etc - everything you need to operate the device, except it's customized by someone in some way.
So what does the "customized" part mean? Since Android is open source, developers are free to take stock ROMs, modify them, strip them of garbage, optimize them, add things, and pretty much do whatever their imagination and skills allow.

- Custom ROMS for Android Explained And Why You Want Them
In the Development Section you will find a variety of Custom ROMs, some require you to have an an Un-Locked Bootloader and some don't, it's usually stated in the thread title if it's required or not but modding your Phone with an unlocked Bootloader is much simpler. Most ROMs usually come in .zip format which require ClockworkMod (CWM) to install them.
You can find a great Guide HERE that will show you how to use Fastboot which is the method used for installing Kernels required by certain Custom ROMS.

- What Is ClockworkMod Recovery And How To Use It On Android
To use CWM on an XPERIA then it's recommended to unlock your Bootloader because then you can simply flash Custom Kernels that come with CWM pre-installed, it's also safer imo because it's separate from the system, but if you haven't unlocked your Bootloader for whatever reason then you're going to have to use [APP]/[RECOVERY]x-Parts [CWM Installer] [Version 7.0] 29/6/12 which is installed to the Phone's system, although it's less effective should you accidentally wipe your system while trying to flash a new ROM as you won't be able to access it.

Hello,
Anyway, I managed to format my phone, how can I restore my phone? I do have CWM installed, but I'm pretty sure that there is nothing we can do now? I can boot into CWM if I want, but there ain't much I can do. Would it work if someone would zip up their entire internal storage in CWM and send it to me, so I could restore my phone? Does it work this way? Anyway, any help is appreciated, otherwise I'll have to order a new phone probably. Oh also, I have stock KDZ file, is there a possible way I could install a stock ROM in CWM mode somehow?
Thanks!
Use this list to find the correct stock kdz for your phone according to the region(Ctrl+F -> type E460 -> search).
Then use the instructions in this thread to flash the stock kdz.
YOU WILL LOSE CWM RECOVERY! But since you want to revert back to stock, this shouldn't be a problem for you.
