Hi folks sorry if this is in the wrong place but I’m very new to this so I hope you don’t find my questions is stupid

My phone is a

LG Optimus P500H

, with android v.2.2.1, s/w version v10b-DEC-13-2010, build FRG83.I have rooted the phone with GingerBreak-v1.20.apk with no problems I have made a full backup with

Titanium Backup PRO the backups in my sd card

Then I find that if I have to do an Emergency mode!!".

I will have restore I will have to use a

CUSTOM RECOVERYWhat would you recommend (something very simple with a walk though

Second where can I find ahd how to Flash original firmware on P500H

and would this return the phone back to factory settings

Many thanks for any help and sorry if this is posted in the wrong place

regards
[Optimus One, P500, V General] dongimin2:
first of all, correct forum. congrats.

You may read my response if you agree not to charge any responsibilities on me. i.e. its all your fault if your phone breaks.

1. installing recovery is getting easier lol

get ROM manager from the market. install it, and run it, the first option should be something like "install clockworkmod" clockworkmod = recovery.

then go to terminal emulator if u have it and type

you will be able to flash roms from then

2. the custom roms can be found here

thank me please by pressing the THANKS button
[Optimus One, P500, V General] sopaipilla:
Hi, first of all do a NAND backup to revert changes to original FW, when is done you can flash and test roms and go back if anything goes wrong.
[Optimus One, P500, V General] GonDr:
AmoRa is the best custom recovery .. ClockworkMod not all roms can flashs with it
[Optimus One, P500, V General] andy4uall:

well am not a fan of either Rom manager or CWM. rom manager can easily brick your device if you do not know what ur doing, best n00bs method is amonra...its foolproof.
[Optimus One, P500, V General] andy4uall:
Can i get cm7 rom for froyo and gingerbread? Also where can i find amonra?

ADB tool isn't working on your Ubuntu/Mandriva/Arch Linux/openSUSE system(Linux)? When you type adb in Terminal you get a command not found? I'll show you how to fix it.

You'll need:

The Android SDK(Software development kit)

Extract android-sdk_r11-linux_x86.tgz and with the Terminal give:

$ cd /home/user/extracted_folder/android-sdk-linux_x86/tools
$ ./android

Download all necessary packages by clicking on "Available packages" and checking "Android Repository". Then click on "install selected" button and another window will pop up. Check "accept all" and click on "install" button. Wait about 30 minutes and you will have all SDK packages installed,adb too.

Go into your terminal and type:

$ sudo gedit [SIZE=4]/etc/udev/rules.d/99-android.rules[/SIZE]

Then paste in 99-android.rules this:

#Google
SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666"
#Acer
SUBSYSTEM=="usb", SYSFS{idVendor}=="0502", MODE="0666"
#Dell
SUBSYSTEM=="usb", SYSFS{idVendor}=="413c", MODE="0666"
#Foxconn
SUBSYSTEM=="usb", SYSFS{idVendor}=="0489", MODE="0666"
#Garmin-Asus
SUBSYSTEM=="usb", SYSFS{idVendor}=="091E", MODE="0666"
#HTC
SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
#Huawei
SUBSYSTEM=="usb", SYSFS{idVendor}=="12d1", MODE="0666"
#Kyocera
SUBSYSTEM=="usb", SYSFS{idVendor}=="0482", MODE="0666"
#LG
SUBSYSTEM=="usb", SYSFS{idVendor}=="1004", MODE="0666"
#Motorola
SUBSYSTEM=="usb", SYSFS{idVendor}=="22b8", MODE="0666"
#Nvidia
SUBSYSTEM=="usb", SYSFS{idVendor}=="0955", MODE="0666"
#Pantech
SUBSYSTEM=="usb", SYSFS{idVendor}=="10a9", MODE="0666"
#Samsung
SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"
#Sharp
SUBSYSTEM=="usb", SYSFS{idVendor}=="04dd", MODE="0666"
#Sony Ericsson
SUBSYSTEM=="usb", SYSFS{idVendor}=="0fce", MODE="0666"
#ZTE
SUBSYSTEM=="usb", SYSFS{idVendor}=="19d2", MODE="0666"

Then in terminal type:

sudo chmod a+rx /etc/udev/rules.d/99-android.rules

Type this too:

sudo gedit .bashrc

Add this to the bottom of the file:

export PATH=${PATH}:/home/YOUR-USERNAME/android-sdk-linux_x86/platform-tools

Reboot your PC.

ADB Is now fixed.

Check if your device is known by adb.

On your phone,go to Settings>Applications>Development and check USB debugging.

Type ./adb devices in the terminal.If you get an output like this:

[I]List of devices attached
XXXXXXXXXXXX device
[/I]

Your phone is recognized.

Great Job ciaox, too bad this guide is coming out now, I completely bricked my phone 2 days ago using KDZ :/ thanks god i didn't even have root, nor a custom recovery installed.. :D

+1 thanks
[Optimus One, P500, V General] luxox:
a question when you say that your terminal type the following code:

$ sudo gedit / etc/udev/rules.d/99-android.rules

as you do because in my case, my phone will start from the fastboot and so I want out
[Optimus One, P500, V General] lekhwani:
Is it really so risky using rom manager?

Or only persons with some Linux know-how should use it?

Where is the recovery flashed?

And when can't we flash a recovery? (Kindly give some info on bad sectors on 5 MB reserved for recovery)
[Optimus One, P500, V General] Bytecode:
Yes do not ever use ROM Manager. And,guide is only for linux. With our fastboot you can only flash recovery image.
[Optimus One, P500, V General] Roqu3:
Hi I unbricked my phone two days ago (after bricked by ROM Manager) using KDZ, is it really dangerous? because how can you restore the original firmware without KDZ?

I use Windows btw

thanks
[Optimus One, P500, V General] ashokabs:
Getting out of fastboot loop

I got into the fastboot problem as I was careless in running a recovery script. I put the phone in emergency mode i.e. return key + volume up key and connect usb to pc. Used KDZ to recover original 2.2.2 and had no problems whatsoever. Took 4-5 mins max.

Would strongly recommend noobs to read as much as they can and be very careful when running commands from the terminal related to recovery installation and flashing ROMS. Also do not use unstable ROMS. Go for those that are most used and with minimum problems/bugs.
[Optimus One, P500, V General] holymolys:
what about using ROM manager to install the clockworkmod recovery? any harm in that? or should i use some other recovery instead
[Optimus One, P500, V General] Master619:
Why didn't I see this thread sooner? ****! Now I have bricked my phone. ROM MANAGER TOTALLY SUCKS!!!

How can I apply your guide on Windows? Which steps need to be changed?
[Optimus One, P500, V General] ppraveen576:
thanks for u r tutorial this will be help full the users who met with fastboot
[Optimus One, P500, V General] Bytecode:
@askoabs: I suggest not to use KDZ because one of my friends used it for flashing original unbrand 2.2 and he COMPLETELY BRICKED his phone.

@holymolys: DO NOT install recovery from ROM Manager. I tried to install it and i got fastboot. I then flashed this and i got out of that malicious loop :)

@Master619: Agree with you dawg,rom manager sucks. Well,it doesn't suck but is unstable. For Windows:

BTW guys why aren't you thanking first post?

Just kiddin' :D

Adding this on first post(windows tut)
[Optimus One, P500, V General] franciscofranco:
I see no problem with Rom Manager as long as people read what they are doing... I installed it and then used it to install the newest CWM (I was running 3.0.2.4 CWM) for p500 and no harm was done...
[Optimus One, P500, V General] Master619:
I still don't know what I have done wrong. I was using void #echo, rooted, then I installed ROM Manager from market, then download CWM 3.1.0.0 through it, then reboot into recovery and my phone is now bricked. So I have a reason to say that it sucks.

@ciaox: thanks for the Windows guide. But these SDKs are taking forever to download.

Edit: now I realize that I DIDN'T EVEN see those fastboot lines. Nothing at all. The phone just reboot and stuck at the first LG logo, nothing more.
[Optimus One, P500, V General] Bytecode:
Yeah but many,many people had problems,me too.
[Optimus One, P500, V General] holymolys:
hmmm.... i only installed the recovery from ROM manager, CWM 3.1.0.0, two days ago before i read this thread, and nothing happened to my phone, im not really planing to flash my phone anytime soon but just wanted to see if recovery worked or not, and it worked... so idk why some ppl are having issues, thats weird

i guess to be safe and just not risk it... i should put in a different recovery via adb shell??
[Optimus One, P500, V General] Master619:
I can't get my PC (Windows7) to recognize the phone. I installed the LGAndroidDriver_WHQL_ML_Ver_1.0_All_Win7.exe from your link. But when I tried adb devices it just show

List of devices attached

And no more line. What should I do now? I tried fastboot flash recovery recovery.img and it shows

< waiting for device >

My phone was in emergency mode. I even tried with my phone in "stuck" mode (at the LG logo) but still no luck.

Edit: do I have to do these part?

$ sudo gedit /etc/udev/rules.d/99-android.rules

and

Then paste in 99-android.rules this:

...

and then

sudo chmod a+rx /etc/udev/rules.d/99-android.rules

Because I don't know how to do them on windows.

One more note: after installing the driver I don't even have the LGE Virtual Modem driver like in many posts say. What's wrong???
[Optimus One, P500, V General] lekhwani:
Seeing all these things, I think I got lucky many times. I have used rom manager to flash roms about 3-4 times. All times successful. 2 times I gave the rom manager command to flash two non-rom zips. One time it was successful, another, it was stuck at LG logo. In latter scenerio I went into recovery which was intact.

I have even backedup Mik's CM 7 and Openoptimus by Ciaox. I have done backups three times.

Once I have restored the backup through rom manager.

But reading all the above posts, it seems I have been lucky 10 times. Or too adventurous.

But now I will think 10*100=1000 times before using rom manager.
[Optimus One, P500, V General] Master619:
OK I finally somehow get the phone unbricked and running the original ROM. Now I want to try the OpenOptimus ROM. So I just do these right?

_ Root the phone. I think I'll use z4root. I think there's no problem right? The original ROM I'm using is 2.2 Froyo stock.

_ Install a recovery. I think I'll choose ClockWork. But this time I don't trust ROM Manager anymore. So can you suggest how can I install that recovery? Will the fastboot method above still work? (I am no longer in emergency mode)

_ flash the open optimus. No problem right?

After all this thing I'm afraid of any small change to my phone, so I have to ask first.

Almost completely copied from here: http://www.androidworld.it/forum/mo...king-optimus-one-p500-tramite-fastboot-17304/

Even fastboot Rapidshare links are taken from AndroidWorld.it wiki, and you copied and pasted even the typo on top ("reser", what a FAIL!), but we knew, ciaox is a copycat, he is a master with c&p. Wasn't Androidworld.it a ****ty forum? But you grab all you can from it. You're getting more and more ridicoluos little boy :D

BTW, mik_os already noticed this long ago. It's completely useless to have fastboot on if we can't get the phone to boot.

AND please, i don't ask you to thank the source, but at least fix your guide.

You don't need to put all that lines on 99-android.rules, the only needed is this: SUBSYSTEM=="usb", SYSFS{idVendor}=="1004", MODE="0666"

This is wrong, adb will never recognize the device while it is in fastboot mode, so this step is completely useless, you'll get only an empty line. At least, you can use fastboot devices, to see if fastboot recognizes the phone.

E hai pure la faccia di chiedere i grazie al primo post :D :D

Cheers.

P.S. @all people Franciscofranco is right. Flashing recovery through Rom Manager is as dangerous as flashing it with "traditional" method. 99% of people had no problems with it. You can enter in fastboot loop even flashing a zip or using flash_image manually. If you don't want to risk, you must not flash any recovery.

About linux: the single ADB binary (300k) + fastboot (130k) is more than enough, there's no need for the SDK at all.

I had to configure the rules file differently in /etc/udev/rules, my device wasn't seen on Ubuntu 11.04 otherwise:

SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="d00d",

Ciaox your guide works good, but we end up with AmonRa on our phones (which is not a bad thing, I'm actually using its v2.2.1b).

Even I experienced the same with ROM manager. After flashing cwm with it, tried to boot into recovery, got stuck in boot loop( at lg logo then, dark screen no fast boot udc). Thank god I revived it through kdz via emergency mode.

The problem I found out was when rom manager downloads recovery the file gets corrupted some times. in my case the file was 4.1 mb, (actually its around 5 mb) may be due to network problems.

So, its better to rely on md5 hash check.

Hi , i have a desire s

SAGA PVT SHIP S-ON RL

HBOOT-0.98.0000

RADIO-38.03.02.11_M

eMMC-boot

and i keep getting "limited service". it might work for a minute or so but for the most part it doesn't. Just wondering is it possible to update the radio or any other suggestions would be appreciated.

I also noticed that on the battery / sim cover there are two metal connectors (slightly scratched), anyone know what they do?

Thanks
[HTC Desire S] ben_pyett:
The metal bits inside the battery case help to make up the phones antenna, so scratches could be a problem.

For example if you remove the case completely, you should see the phone signal drop to zero after a few seconds.
[HTC Desire S] psycho_somatic:
Thanks for the quick reply.. :)

hmmm thats what i figured, know any place i could get a replacement cover?
[HTC Desire S] ben_pyett:
I've previously read on the forum that it wasn't possible to purchase a new cover, that was in threads regarding build quality from people who were having problems with the battery cover making a clicking noise, but that was about a month ago, and the device was reasonably new then, you may have more success now, try calling htc support/customer services and request the part?

if you could find someone with same device and try thier case for a few minutes at least you could then determine whether it was this that was causing you the signal problem.

There is the HTC accessory store http://www.htcaccessorystore.com/uk/p_htc_phone.aspx?i=209276 but on quick inspection I couldn't see that particular part.

Best of luck
[HTC Desire S] psycho_somatic:
thanks

another thing is that it might work to make a call, and then loose the signal. i read that a blocked imei number could cause that. I bought this on ebay so who knows where it came from...
[HTC Desire S] ben_pyett:
You network service provider should be able to confirm whether or not the IMEI number is blocked
[HTC Desire S] psycho_somatic:
ok so i've checked some things... the imei isn't blocked, the cover isn't the issue either as it works with that off (albeit a little weaker). it works for a minute when i put it in and out of airplane mode... oh and i tried another sim i had and that one wouldn't work at all
[HTC Desire S] ben_pyett:
So its either a local network issue or a device issue, have you performed a hard reset as yet?

Which would rule out it being software
[HTC Desire S] psycho_somatic:
just to be sure (i think i have) but how do you do a hard reset?
[HTC Desire S] ben_pyett:
Theres a couple of ways, the easiest of which is

Settings-> sd & phone storage

And select factory data reset.

But, I be tempted to try the harder route which is

Power down phone

Remove battery for a few seconds, re insert it

Hold the volume down button

Press power button

Follow on screen instructions and select clear storage

This will wipe all on phone data and will reboot phone
[HTC Desire S] psycho_somatic:
thanks i wasn't sure. Had tried that before but i did it again and its still the same..

am, i'm testing with a three sim and it works intermittently then i tried another newer three sim that i have it didn't work at all but just now tried an o2 sim and it worked perfectly, now i'm lost ha
[HTC Desire S] ben_pyett:
In which case it could simply be that where you live has very little 3 network reception.

I'm not sure if 3 has network coverage maps available online which would enable you to check the expected signal coverage where you live/work.

Perhaps you need to move to O2 network!
[HTC Desire S] psycho_somatic:
nah my three signal is perfect, plus I've tried it in other locations, i'm stumped and i really dislike o2 so i won't be going back to them.... hmmm
