[SIZE=+2]LG Optimus One Device Family[/SIZE]​
[SIZE=+1]This a short list of frequently asked questions in this device forum and the answers often given as a response. It should serve as a starting point for gathering knowledge and finding solutions to many common problems. Please only post in this thread with feedback on how to improve this document. Do not post "Thank you" type responses. If you have additional questions or require more help, try to find an existing thread or create your own. Do not use this as a general help thread.[/SIZE]
[SIZE=+1]Q1: How do I root my LG Optimus One?[/SIZE]Rooting can be accomplished with Gingerbreak.apk 1.20 for most devices running stock Froyo ( 2.2 ) and Gingerbread( 2.3 ). There is also Z4Root and SuperOneClick for those instances when GingerBreak doesn't work.​
[SIZE=+1]Q2: How do I install a custom recovery?[/SIZE]This is too broad a topic to cover in detail in this FAQ. Please refer to any of the methods listed below...
Install recovery with 'flash_image' binary or LGMDP
All in one how-to for rooting, installing ADB, installing recoveries, etc...
Install ROM Manager from Play Store. To use ROM Manager you MUST be rooted. Use ROM Manager to install a custom recovery.
Most P500 and P505 models got their official updates. Choose the Optimus One item
The P506 and P509 did not get official updates. Choose the Optimus One (OldBB) item
Device models not mentioned, old baseband models choose the "Optimus One (OldBB)" item. New baseband models choose the "Optimus One" item.
There is also my utility Android Flash Recovery to flash a recovery via fastboot and fastboot mode.
[SIZE=+1]Q3: Why do I have to "trim" my ROMs?[/SIZE]
The allocated system partition on any of these devices is only 190 MB. Not really huge. However since Android 4.0, the space required for everything has increased to a point that it will almost completely fill the system partition only leaving a few KB free. OOne ROM Editor is a Windows utility designed specifically for this task.​
[SIZE=+1]Q4: I've flashed ( any ICS or JB ) ROM and Google Apps. Why doesn't my Home and or Search button work?[/SIZE]Did you trim the ROM prior to installation? If not, see question #3 above.
Did you wipe your /cache and Dalvik cache prior to the ROM installation?​
[SIZE=+1]Q5: Why doesn't Link2SD work with CM10+?[/SIZE]
There are several reasons. There is an actual procedure required in order to get Link2SD to work properly with these devices.
The ROM must be trimmed prior to installing or immediately after installing on to the device. See question #3 above.
The biggest issue with Link2SD is the lack of free space on the devices system partition. I recommend a minimum 1024 MB ( 1 GB ) partition on the sdcard, formatted as ext4.
Now install Link2SD. After it installs, open it and let it create it's mount scripts.
Reboot device. On this first boot Link2SD will create it's symlinks and move whatever files it needs to move.
Reboot device once more for good measure.
From here, assuming that you have removed enough from the ROM when trimming it, the Google Apps package should be installed via your preferred recovery.
Reboot. You should see a "Android is updating apps" notification as the ROM starts.
[SIZE=+1]Q6: How can I get rid of Link2SD before migrating to another *2SD script?[/SIZE]
Link2SD installs scripts etc. in 2 places
/system/etc/init.d
/system/etc/install_recovery.sh
Delete both mounting scripts and delete the /data/sdext2 folder to get rid of Link2SD. For credit and more details please see this post.​
[SIZE=+1]Q7: I have installed CM10.1. What happened to the Developer Options?[/SIZE]
On the device, go to Settings -> About Phone. Scroll to and tap on the build number 7 - 8 times until you get a toast notification that states that Developer Options are enabled. Press the "Back" button. A Developer Options item should appear in the main settings list, usually just before About Phone. Press the Developer Options item and then enable Developer Options with the toggle at the top of the page.​
[SIZE=+1]Q8: I'm running CM10.1. Where is the advanced power menu?[/SIZE]
If Developer Options are not enabled, see question #7 above. Go to Settings -> Developer Options and enable "Advanced Reboot".​
[SIZE=+1]Q9: I just flashed a ROM and I have no network. What should I do?[/SIZE]
All ROMs from CM7 and newer are built for new baseband. This is more than likely because of the wrong baseband. The P509 and P506 are old baseband devices. P500 and P505 devices that didn't get the official update are also old baseband. You can flash the old baseband patch via CWM or any other recovery to remedy this problem. Please see post #8 for the old baseband patch.
It is also possible the the APN for your carrier is either not set up or is incorrectly set up. ​
[SIZE=+1]Q10: What is the best method for installing a ROM?[/SIZE]
In my opinion it is always best to perform all wipes, even when upgrading the same Android version, although it is not really required when upgrading. The following steps are assuming that you are using CWM.
Boot device in to Recovery. If you don't have a custom recovery, please see question #2 above.
Perform "Wipe data/factory reset". This will format the /data, /cache, /sdext, and .android_secure
Select the "Advanced" option and on the next screen select "Wipe Dalvik Cache". Confirm the wipe.
Not necessary but I do it anyway, in the "Advanced" screen select "Wipe battery stats" and the confirm that wipe
For a clean installation I recommend formatting the system partition too. From CWM home screen select "mounts and storage". On the next screen select "format /system" and then confirm the format.
Press the back button until you are back in the CWM home screen. Select "Install zip from sdcard" and then select "Choose zip from sdcard". Browse your sdcard for the ROM to install and select it. Confirm the installation. Now wait for the install to finish.
Go back to CWM's home screen. Select "reboot system now" option and let the device boot. The initial boot will take a couple of minutes. Don't panic.
If you intend to install any patches or Google Apps, reboot device into recovery and repeat step 6 for each additional package to install.​

A: Link2SD installs in 2 places, /system/etc/init.d & /system/etc/install_recovery.sh
You need to delete them both mounting scripts, and also delete the /data/sdext2 folder to get rid of link2sd...

We need a list of working *2sd with cm10/10.1
Does this F.A.Q. meant to be only for cm10/10.1?

No. It's not meant for any specific Android version at all. This FAQ is still a WIP. This FAQ is intended to be a starting point for new members. It is not designed or intended to go in to too much detail about anything. Questions with lengthy answers are answered in short form when possible. If more explanation is needed, then a link or links will be included to direct the member to the correct thread.
As for what you have stated, I will see what I can come up with. Some of the *2SD scripts can be problematic setting up and require special details. Link2SD and Mounts2SD are two problematic ones right off the top of my head.
Thanks for the suggestion.

will all roms will work on this baseband

That "oldbasebandfix.zip" is to make a new baseband rom work with a phone that has old baseband. Check the thread for the rom to check for baseband requirements.

I'm afraid that I cannot personally answer your question. One note, this is not a general discussion thread. Please read or reread the OP.

Ok so I have a couple of problems with my p500.
First of all my phone, doesn't want to connect to my pc. I don't have a clue why, I think it happened for the first time a long time ago while I was fidling with it (can't remember what) and once it connects, my computer says that the device got disconected when it is still connected! I've tried to factory reset but nothing happened still the same.
Secondly the problem that I have is that sometimes the phone boots into emergency mode for no good reason.
It is running on 2.3.3 android and it is not rooted or anything but stock!
Looking forward for your sollutions guys!

This is not a general help thread. Please reread the OP. In this case you should've started another thread. But in any case...
A partial answer to your question can be found here
Sounds like the drivers need to be reinstalled on your PC. They should be uninstalled, reboot PC, reinstalled, and reboot once more. Power off your device. Attach data cable to device assuming its already attached to a USB port that is not a hub. Now power on the device and let the driver installation do it's thing.
The above is assuming you've managed to get your device to properly boot.
Best of luck.

Hello everyone!
Since xda won't let me ask directly in the relevant thread (as I am a 'noob' here), I guess here's the correct place. So here we go:
Does anyone know how to enable a hardware video playback on P-500 with Evoking 2.1 ROM (Skydragon)? I use Mobo Player, and in several earlier versions of Evoking it simply did a software mode fallback. Tried V-Player, but it simply crashes (as well as 'Now playing' and some other media-related apps in this ROM).

Android L - Sdcard error specific thread...

I know it's another L thread but bare with me!
I'd like to figure out (without all the other chat getting mixed up with the other threads) the sdcard missing error issue as it's bugging the hell out of me and others...
disclaimer - yes i know it's a preview! But.... We all have the same device coming from the same firmware to the same firmware...
when I first flashed L from vomer's zip, with the then modified boot.img and su zip everything was fine. I could use the camera, see my files and pictures in the photos app etc.
Then I went back to 4.4.4, ever since if I try to flash L. Either with the new su zip not needed modified boot.img. Or the original way including it. I just get sdcard missing in camera. No files seen in photos or any file exporer.
And I know others have too.
I've tried the 3 different restorecon commands in terminal emulator that's been floating around etc but always nothing..
So what's the defining difference??
Why could i see it fine the first flash but never again since??
I know some have no issues what so ever where as others have had to do full wipes for it to be seen.
But we all have the same phone, same hardware and same firmware??

I flashed L, got tired of it, restored my backup 4.4.4 ROM and had no issues. Flashed L again, but this time I didn't restore a backup, just clean flashed my 4.4.4 ROM and now I'm getting the no SD card error as well.

I did the same thing. Ran L for a couple of days, made a backup and restored slimkat just fine. Went to restore L backup and it wouldn't boot and it screwed up my partitions. So now I just backed up my SD card (the one showing my stuff actually in it lol) and will be restoring to stock and starting over tonight to hopefully fix partitioning issue

That's why I use MultiRom

first time I flashed, it was a dirty flash, and all was fine, just the pulldown wouldn't go down all the way. second time i flashed, I "lost" my storage. but I was in recovery(twrp) playing around with their file explorer, and accidentally found all my storage/files. I booted up, used root explorer to move all my files manually from the original location that got moved, to the new location where they should be. everything was fine after.

Don't know y exactly but flashing the user data.img works to get SD card corrected. I'd wipe everything including data then flash vomers zip and the user data.img that's posted I believe on page 23..

I know we can do that. But this is more to figure out why second time flashing screws the internal memory up?
Sent from my Nexus 5 using Tapatalk

Same exact problem as me. @Ben36 I played around with Restorecon /data/media/0/* and it bit me. I wasn't able to boot up in MultiROM. Mananged to boot into 4.4.4 by way of erasing internal ROM. Backed up my install, and flash-all L image.
I'll agree that the Sdcard issue is HELLA confusing. Good thread man.

Asking Ambychy (or perhaps anyone else willing and able to assist)
From http://forum.xda-developers.com/xperia-j-e/development/xperia-e-tools-t2841797/page2
First of all thank you Ambychy for this thread thus helping noobs like me.
From your thread http://forum.xda-developers.com/xperia-j-e/development/xperia-e-tools-t2841797
I have downloaded the following :
Xperia E ss stock Deodexed Rom.zip + Xperia E Dual stock Deodexed Rom.zip
Im TOTALL noob at flashing ROMs (especially remote-wise via usb).
I manage to root my ("Xperia E C1505", I belive was called) through some youtube video advice...
Some Indosiean (I think) modded rootmaster thing. Whatever... I had too because for some reason I could not get Frama solution to work, but this did....
So anyways... Now Titanium and all that worked.
My problem is :
I managed to screw up my phone. I certain its hardware-wise ok...
Long story short = its stuck at "Android is updating" forever and ever until I psycichally remove the battery.
I cant back into it. software-bricked.
I removed too much from the ROM as I had faith in using Titanium to restore my saved system-apps.
First making them into user-apps and removing them that way, later on leftover odex-es in "system/app", all dalvics and
whatnot whould do it. To lastly finish off with "make phonereset" via normal "settings"...
I was stupid...
After removing most, and about to reinsert later on via TB, I took a wildcard and removed "Home" aswell.
It was stuck in an infinite loop of pressing ok on it as it kept saying "blah had crashed" without ANY gaps in between at all, leaving me no choice but to reboot and sending a prayer I at least come back into it to continue restored sys-apps via TB.
So i belive i must use some remote PC program to reflash it...
So what program for my PC do do you recommend I use?
(and it even more kudos to you if you can direkt me where to grab it).
I also got a 4 GB external memory.
Perhaps putting whats in the zip onto that via another phone, then moving that external back into my broken one might do the trick?

[Completed] [Q] Stupid mistake flashing OPO with cm 12.1

Hi,
just want to flash the latest cm 12.1 nightly to my still 11s OPO. I copied the image, gapps and supersu to the storage, rebooted to twrp and wiped dalvik, system, data and (please don't ask why, I simply did it) internal storage :silly:
I have no idea how to transfer anything to the phone know, adb does not find any device of course. If I try to sideload, the OPO console tells me I have to use adb 1.0.32 or higher. I use 1.0.32. Is there a way to flash or transfer data using fastboot?
Thanks for any advise, even that I'm sure it's a noob question.

read much, post less...
I found the noop corner and understand the difference between a flashable image and installable distribution now. Found everything I need, simply ignore or delete this thread :angel:

Glad you found your answers.
Yes search and read more is always the best solution on XDA.

sp_flash ROM Backup a MT6779V/CE Device - Tricks&Errors

According to a hint de-scripted here: https://github.com/do1fmd/BV9900Pro-optimization
It is possible to build a full rom dumb of a Blackview 9900pro device just by enabling the
[ReadBack]
ShowByScatter=true
in the option.ini in the sp_flash tool folder.
I did this procedure, did successfully a fully backup which included 42 Partition Files, labelled from ROM_1 till ROM_42. I modified the scatter file for pointing to the new Names, like preloader to ROM_0, recovery to ROM_2, misc to ROM_3 and so on...
Then i did a test restore to make sure, this works. Unfortunately, for some reason it is not.
After restoring the device, which process went through without any error, the next boot went first normal, logo and animation apears, then it reboots again and goes straight into the Recovry, showing in red letters a failure "cant load android system, your datas are proparly damaged" with two options to select: retry or reset to manufacturing default.
Its a rooted Android 10, Partition is not encrypted.
Is someone doing the same way of ROM backups and successful restoring them? Is there a partition which must be included in the download procedure? or what else i am missing here?
