[Q] please help ! Pc cannot detect LG optimus one - Optimus One, P500, V General

Hi
I had rooted my LG Optimus one and had deleted some applications with Titanium backup.
Now when i attach my phone to any computer it is not getting detected. i tried resetting the phone to factor default, reloaded drivers and LG pc suite . tried almost everything possible.
It is not even going into usb mass storage mode. The device manager on PC too does not detect any usb conection happening. Everything else on the phone is working fine.
Is that any usb related module on the phone got accidently deleted ?
Whats the possible solution now ?

Have you checked the USB-MASS STORAGE option in SETTINGS-> SDCARD & PHONE STORAGE SETTINGS ?

yes
yes i have done everything . selected mass usb storage too..
the problem is that no PC even detects a USB connection happening when i attach the phone

This happened to me twice now... I just sent it in to the LG service center. The tech guy said he did a "software update" which I took to mean reflashing the original ROM all over again.
I recommend doing a KDZ update if possible then install custom recovery and do a nandroid backup so you will always have a failsafe.
Dont take my word for it yet though... Hopefully someone else can enlighten us. I now use the void custom ROM so that there will be no unnecessary apps on my phone ^_^

Dear all, can any body tell me how much space is required on sd for nandroid backup?
I have limited space on stock sd card.

IIRC, around <500 MB. Each backup you make wont overwrite the last one so watch how many you make. But this is actually a good thing. And each backup type you make (nand, nand + android secure, etc.) also makes its own folder.
Backup and try to restore first to see if it works (backing up the nand+anything else didnt work for me).

Thanks a lot. I believe I'll have to delete some files on sd. And after that I can make a nandroid backup. I also feel we can copy the backup to pc and can use it later if need arises?

I believe so as long as it is in the correct folder where you found it.
What I feared for my phone before was that I cannot do a KDZ update because the PC wouldnt see my phone and I did not have custom recovery installed (nor a backup obviously...). Thats why I sent it to the service center...
When I got it back, I didnt abuse my phone as much (used it for call and text only) until I was finally able to install custom recovery ^_^

Important update
Hi guys
I had gone to the LG service station. Got my phone re-flashed with the latest firmware V10C . But the PC still can't detect the phone .
Now LG is giving me a new handset in exchange. They say its some problem with the hardware.

any info u might want i am open to tell you (like my kernel version etc) i just dont know what u need to "solve" my problem ;d just ask!

bump
so i somehow managed to downgrade my hero, flash it through recovery and i can access the new menu from home + power button but it still says am not rooted... any ideas?:/
You have achieved major hurdles.
To get root you have to flash rooted rom like Mocado's. I have v2.8 which I think has everything I wanted. You can have your own choice>>>

if i flash a rom do i loose my messages/contacts if i DONT backup?also can i partition my SD without rooting? and i have already tried Amon Ra with better terminal emulator but it fails ;d btw if possible try pm me
f--k this-.-
after all the good progress i've had..
i managed to root it, partition my SD and when i tried to move my apps it, midway, it asked me to restart my device..so i did.. and now all my apps are gone, factory reset has been made, contacts are lost, messages are lost..almost EVERYTHING is lost apart from application shortucts-.- :S i have made a backup but i dont know how to use it (lol-.-) pls reply
freaking p----ed...
sry for all the bumpness.. really in need of help
whenever i try to fastboot it says not allowed..and am about to cry..
stupid nandroid backup cant get it to work! pls help!
You flashed Amons recovery... With it you can format and partition sd card, and flash rom of your choice.
Yes you loose everything when flashing rom. You could have copied your contact on sim or sd, same for applications. You can reinstall but a word of advice,
Do your wipes first, I mean to ensure smooth running of rom. Hope it helps.
And when not sure please read, read and read, we are all here to help one another. Regards.
how can i do a backup for my contacts and messages? i have the .img files ;/
when i fastboot it says remote: not allow
also htc sync doesnt work now
and when i restore from recovery boot it says nandroid mobile sh failed run via console ;/
No dont flash .img.
Re- restoring contacts, I dont know any easy way but all your sim contacts can be copied. All phone contacts will have been wiped ,that swhat happenes when we install new os.
i thought it was the other way around and i copied everything on my mobile.. lol..
anw doesnt matter ;d just had 40 contacts anw ;d
can i restore messages, application saves and application folders at least? btw my phone aint working on htc sync now ROMS are still on btw
and how can i correctly partition my SD so any application i add it is saved on SD?thx ;d
Just one thing. Refrain from using foul languages as this forum is open to all ages of members and it will also reflect bad on you.
Install something like Astro, open it ,click menu and go from there to back up all your installed apps.
yeah sry forgot :/
will edit it right away
also thats what i mean, all my apps and their saves/settings are on backup.imgs :/ my hero is like a brand new one with modaco installed and nothing else... and htc sync doesnt load it, although i can use mass storage
Back up images are actually of rom itself. Sorry I dont know how to reinstate sms messages. This questiones was asked by a friend about his iPhone and again I couldnt answer as I never owned iPhone.
Anybody out there to answer question raised in above post?
meh doesnt matter i guess
i'll just "rebuild" it from scratch ;/
just wanna know what to do now so i get a partition on my SD.. i have a 2gb card which was partitioned before but i restored it.. i want 2 things
1) howto partition it for automatic saving apps on SD! and not having to move them everytime
2) how to make HTC sync works -.- i think i "broke" it:S i reinstalled it 4 times so far..nothing..
1) Format and partition feature s in your recovery. Format the whole card as fat32 and next make partition but again you will loose everything on card! After that you will need to mount your sd card ( option in recovery) so that you can put copy back everything on it. But why do you want to do it if everything is working?
2) Do you see ADB in system properties? If yes, drivers are installed correctly.
It is worth browsing Dream forums as Dream was first Android phone hence more to read and almost all can be related to Magic and Hero units operational practices except rooting and flashing bits.
one last thing man
atm i am looking for another application to connect to my hero to install other apks :/ currently i have apps2sd on hero although and i was wondering if all i have to do is Copy apps to SD and thats all? (whats dalvik cache that asks me to copy btw?)
i asked about formating and partitioning cause i am getting an 8gb in a few days and i was wondering if i should do it like that
and no i cant see ADB in system properties ;o how can i install the drivers ;/
1) i've read that modaco doesnt work with HTC sync anymore sometimes.. so i was wondering if there is anyway i can install apk without htc sync?
(tried with adb had 2 different errors)
2)is there anyway to like load 2-3 roms and swap between them without loosing anything? (if yes, how)
thx
edit: i reinstall htc sync and my drivers are gone! cant get them back..my pc doesnt even load APK files! :S

deleted photos in the interenal storage

like the title says i deleted a whole folder of photos of my daughter by mistake. is there anyway to get them back, anyway! money no oject, they was and are very important to me i am madly saddened.
thank you adam
You can try recovery softwares on your PC like easus data recovery or such. Just plug your phone via usb. Havent tried it though but it wont hurt if you give it a try.

Try this: http://www.squidoo.com/recover-deleted-photos-from-galaxy
Or this: http://www.slideshare.net/Selena201...deleted-photospictures-from-samsung-galaxy-s3
Or: http://www.wondershare.com/data-recovery/android-data-recovery.html
Of utmost importance is that you immediatly stop using your phone until you are ready to use a tool to recover files
since any activity runs the risk of overwriting the photo data.
However I'm not sure if any of the tools really work on the S3. Reason being that the internal storage where the photos are often (but not always) located is not USB-mountable on the S3 (regardless of what some articles linked here claim, it's not true, Easy-UMS can only mount the external SDcard)
The data exchange protocol (MTP) on the S3 is not able to restore files, you'd need a tool which runs on the phone itself and has full root access. I'm not aware of any such tools, especially not working ones. This does however not mean you should give up.
You can take a backup of the EXT4 partition through dd so you can attempt to restore it on the computer while continuing to use the phone.
On a sidenote; can anyone confirm the S3 is not using TRIM on it's SSD? Since that whould effectively make any restore attempts pointless due to the data already having been physically wiped a long time ago.
I had this issue too and spoke to Samsung Directly..there is no way to do this on INTERNAL memory! external yes
I did that last week
So the solution is download undelete pro from Market and it will recover 98% of your lost photos & Videos, but keep in mind that you shouldn't use your storage meaning take photos, copy files, etc... just straight to market install the app and it will do an almost perfect job.
Hope this helps.

[Q] I installed a new CWM via CWM and lost EVERYTHING! Please Help!

I was installing the new RR KitKat via clockworkmod but got an error stating "set_metadata_recursive: some changes failed". I goggled it and many people were saying I need to get a newer version of CWM. Since I usually install things by booting CWM I thought there couldn't be too much harm in installing this new CWM via my old CWM. Boy was I wrong. Everything in my internal storage was deleted. Literally said 11.78GB of 11.78GB free. My heart skipped a beat. Videos? Gone. Music? Gone. Pictures? Gone (still hurts). Even my nandroid backups and titanium backups were erased. Surprisingly, despite this, my phone and apps work perfectly well.
Thank God I made it a point to use onenote and google task to write down my notes or else I'd be crying behind a glass wall of emotion right now.
Is there anything I can do to get my stuff back?
You can use usb mode of your phone and connect to your computer as a usb drive, then you can use a software like recuva and scan for deleted things. Recuva is free as far as i know, you can use any software that rescues deleted files.

[Q] Data Recovery after formatting :(

I had recently rooted my phone and then installed CyanogenMod OS on my Samsung S3.
For installing cyanogen it formatted my phone, now I recall that I had some important data in my Mobile Vault app that I want to recover, most of the recovery software are unable to detect the mobile.
When I try to change it to USB mass storage device, it does how up on the PC but I cannot access it.
I had also created a backup image using ROM manager but it too got deleted in the process, if by some method I could get it back or if I can somehow make my phone be discovered as a mass storage device, I might be able to get my data back.
Sorry if I have posted in the wrong section. Any help would be appreciated I am struggling at it since the last 4-5 days.
There are hundreds of identical threads, I've not heard a single success. Sorry.

Well, If your phone is recognized by windows and you can connect as USB maas storage then use windows recovery softwares which can recover your data but it is very much time consuming may be you have to let your phone connected to pc for a day or 2 and if you have luck you will get back all the data. but its a 80:20 game.

[Q] Transfer suggestions (from Z1C to Z5C)

Hello!
Can anyone give me any hints on what is the best option to transfer my data?
I usually have always used TiBackup because i went from rooted phone to rooted phone.
The Z1C is BL unlock and rooted Kitkat Version 14.3.A.0.757. I have played around with Backup and restore and for some reason it fails to make a backup on the Z1C for me although there is enough space in both internal and SD card. It just fails, maybe due to root.
Then I installed PC Companion and tried to backup from there to no avail. It keeps bugging me to update the old phone. Maybe this is why that fails.
Then I tried the direct Transfer Option (phone to phone) which seems to get as far as the phones connection. Then the receiving phone (Z3c) goes into a loop as it supposedly looking for content on the Z1C to select and transfer. This takes ages, so I believe it might fail, although I am still waiting for it.
Is there any program that is capable of creating a backup file on a rooted phone which is completely installable on a non-rooter? Including data and settings etc.?
Has anyone handled this issue before?
I am scared to try and just update the Z1C as the Companion keeps suggesting for losing root on that phone would suck and I am not sure how hard it is to get that back...
I tried adb backup.
It worked reasonably but some issues..
No comparison to titanium backup..

i had good experience using Helium when i transfered my apps&data from my old phone to the z5c. I bought the full version since direct transfers between the devices seemed to very convenient thing for me.
