So my LG G watch is the latest one 5.1.1 and i rooted it but then i tried to flash a custom rom and it just sits at the LG screen with the little lock on it, i can get into boot loader and TWRP recovery, What do i do? when i exit TWRP it says you dont have an OS installed. Could i just flash the factory image in TWRP?
use the tool to go back to stock lca43 or z22d

Probably. Alternatively, if you can get into TWRP, use my backup. Go into TWRP, make a backup of your broken setup first, then push the backup folder (LCA43) to the TWRP top backup folder (probably "/sdcard/TWRP/BACKUPS/dory/", but you can adb shell to explore this). Then just restore my backup. You will want to factory reset once that is done.
Hope this helps.

Shouldn't have to mount anything. Just use " adb push LCA43 ‹path to dory TWRP backup on sdcard› ". Use " adb shell " to cd and ls for your destination.
i got it all done. Thank you.

I am an newbie for the android world and lokking for the article about how to backup the rom of LG P500 for several days.
There are many articles about HTC's rom backup and recovery but I dont know it works for P500 or not.
Could any one tell me how to do or some apps I can download to backup full rom of P500?

I know about way, that you flash the custom recovery into phone and then boot into it and choose backup. But I have question too - is it possible to make full backup without install of custom recovery?

What you said is the point. If I flash the custom recovery into the rom, I'll lost the warranty. So I need to backup the original rom in other way, apps or adb command.
any tutorials?

I'm not sure, but I think that it will be problem. You can not make dump of system if this system is running = you have to run some another "system" which is independent on system which you want to backup.
What are you thinking guys? Or can be make dump of system which is actually running?
I haven't tried yet to flash or to use a custom recovery, but I suppose that if you run the recovery without flashing it (via USB and ADB), you will not loose anything at all.. exactly like I did for my HTC Magic a while ago..
If my idea is correct, you can plug the cable, make a backup of your phone as it is, then do whatever you want

If someone can find an early lg test rom or earlier than first shipped rom from lg updater that the bootloader allows fastboot there is a way to boot recovery via fastboot without flashing it. Without fastboot you have to actually flash it. You can easily backup your stock-recovery and reflash that back if needed for warranty etc.
If you would like to back up your stock recovery you can do it via this command from a root shell PRIOR to flashing recovery
Code:
dd if=/dev/mtd/mtd2 of=/sdcard/stock-recovery.img bs=4096

Without a leaked rom with fastboot enabled bootloader then no as nandroid has to be run from recovery.
I have found the rom version v10h of LG Optimus One P503 (P500 in China),
here's link: link.52lg.com/52lg/GSM/P503/P503-V10h.rar
but I dont know it's reality.
With fastboot disabled, you can't backup your rom without flashing a custom recovery. And it seems nobody has found a way to enable fastboot yet. See also this thread.

Or in phone use "Terminal Emulator" app and type this command via it.
Hi all.
This is an interesting topic to me: the hard reset is able to restore a "warranty included" situation (obviously loosing any data in the internal flash memory)? What exactly does a hard reset on LG Optimus One?
thank you.
Will this command enable me to backup the default rom without installing a custom recovery rom? If so then how can I restore it later on? Will it keep all my current applications, cache, data, system definitions, etc?
No, this command backup only original recovery.
If you install custom recovery for make a nandroid backup, you can return back of the original recovery, just like that warranty is not lost
Sounds great, I want to do a Nandroid backup but was kinda nervous about losing the default recovery permanently.
So what would be the command to restore the original recovery if necessary?
You only posted the one to do the backup : )
Hi guys.
So i've a question: How can I flash my backup of the stock-recovery?
I did the backup how it's described here.
I've got the drellisdee custom recovery.
Do I only have to flash the recovery via the custom recovery?
Do I have to delete the files which I flashed when I did flash the custom recovery?
Thanks

NO, you can't flash recovery via custom recovery,
NO, you don't have to delete files what you are already fleshed.
For restore just enter command
Code:
flash_image recovery /sdcard/my-original-recovery.img
You don't have to do rest of command.
Sorry for all the noob questions which follow, but I've tried reading up on related stuff & still feel lost. Also, the above posts answer the questions already, but I'd still like some clarification/confirmation. Thanks for your patience & time. Much appreciated.
1. When I open Terminal Emulator on the phone, I get this blue screen which says-
$ export PATH=/data/local/bin:$PATH
$
Can I simply copy paste the given command viz. dd if=/dev/mtd/mtd2 of=/sdcard/stock-recovery.img bs=4096 next to the above prompt & get a backup of the ROM? If not, what else needs to be typed in?
2. & can this same ROM be restored using the command given viz. flash_image recovery /sdcard/my-original-recovery.img at the same prompt? Would restoration then put the phone in a state whereby LG cannot know that the phone's ROM had been changed & thus make it eligible for warranty?
3. Will this save contacts & messages as well, or do these need to be backed up separately?
4. What does the 4096 in the command signify?
Again, thanks a lot.

+1 I have the same question. Please help us.
So, I have a HTC Desire with Android 2.2 on it. Some time ago I rooted it with the unrevoked program. Everything went fine, until the phone rebooted in recovery(after the root process). In ClockworkMod recovery, it gave me 5 errors like: Can't mount Cache. Then I realized that nothing in recovery works, not even the factory reset.
I wanted to flash a new recovery (AmonRa) with the terminal emulator ('cause the recovery flash function won't work), but it didn't recognize the command "flash". After some research I found out that I have to "put" the command file in xbin on my phone so that it could work. The "flash command" file has 3mb, but i have only 2mb system memory free.
Ok, so I ditched the recovery problem, and installed the "root" uninstaller so I can uninstall the default Flickr app on my phone. But, whenever i try to uninstall a system app, the phone reboots and the app doesn't uninstall. Same with the Titanium Backup "integrate update into ROM" function.
Sooo, first question: How do i fix my recovery so i can flash a new one? Can i flash one using Adb?
Second one: Does the rebooting of the phone when i try altering the rom has any to do with the recovery errors? If no, then:
Thrid one: How do i fix the rebooting?
1)You need to make sure that your fastboot and adb are configured correctly first of all, if adb/fastboot doesnt recognize "flash" then you probably are in the wrong directory in CMD prompt. Yes you can flash a recovery and even a rom with a properly set up adb
2) All I can recommend is try flashing a new recovery and start fresh. If the new rom continues to reboot then that is a whole-nother issue.

Sounds like your CWM needs to be updated. Simple way is to download Rom Manager from the Market. Open it and Flash the latest Recovery for your device. Yes as the person before me stated. If correctly setup you can Flash a Recovery, and even a Rom throught ADB. You can also remove unwanted apps, or push apps to the phone. HERE is a good guide about ADB. Also another good one is HERE.
I tried to install a KitKat Rom but ended up having my One boot up and reboot to recovery. Unfortunately I decided not to make a backup because I felt I had gone through the motions enough times to know what I was doing, and now I can only boot to the Rom that won't work. I found another rom that I used before sitting in my computer, but I can't seem to use adb to push it (unless I'm doing it wrong) into my phone's storage so I can use recovery to boot into it. Help!

First kitkat roms require s-off and the newest version of TWRP 2.6.3.3
so you can update your recovery and get s-off and reflash the kitkat or you can push the old rom you have to the phone.
http://rumrunner.us/ for s-off
recovery is here - http://techerrata.com/browse/twrp2/m7
ADB Push from Recovery
adb push rom.zip /data/media/0/
the file you push must be in the same directory as ADB

I did the same thing yesterday, as it was my first time using TWRP (always been a CWM guy), All you have to do to fix it is go into advanced and go into adb sideload, put your rom in you adb folder and run this command
adb sideload nameofzip.zip
Then the zip will be placed in internal storage named sideload.zip and you can flash it.

I would try to plug in the USB after your already in recovery.
If you cant get that to work you can always buy this:
https://shopmeenova.appspot.com/st/order.html
its a microusb to microsd its a good worst case and will get you up and running.
do you still have the rom that errored out on you on your internal storage? if so you can always try a fresh wipe and try to install again.
Hi, i recently got new phone and manage to break it in few hours trying to install cm-11-20140130-NIGHTLY-enrc2b and forgot to do nandroid backup.
I want to go back to stock rom but i can't figure out how to do anything.
After i cut my sim card to mini size i don't have any other phone to use with it so i need to fix it asap. Please anyone help.
Flash the boot img in fastboot . Just google how to flash fast boot. The boot is located in the rom zip . Or try to run the latest ruu specific for your phone

You have a custom recovery installed , i suppose..TWRP? you should ADB sideload a custom rom. If you have international or AT&t version both are available in the Rom sections(http://forum.xda-developers.com/htc-one-x2/development?nocache=1) . Before doing sideload erase all.
Goodluck.
I have CWM installed now, tried to install from sideload but didn't work, "error: device not found" or "device offline"
Installed TWRP and adb sideload don't work anyway. Or wait, it worked. Sending now.
After installing, i press Reboot System and "No OS Installed! Are you sure you wish to reboot?" warning shows up. After rebooting i'm back to start.
Just tried to install other custom rom and still phone won't go past that screen.
ok stop
breathe
sideload a new rom on twrp (is a pain) it will never flash 1st time
once it's "sideloaded" you can install a zip called sieload.zip under the rom install menu.
MAKE SURE you wipe
data (not storage) system and cache
INSTALL the rom
fastboot flash boot boot.img in the bootloader
reboot
adb shows up "error: closed"
adb shows up "error: closed"
used adb kill-server and start-server and error gone
And still does not start, stuck at white htc screen.

ok, you NEED the boot.img from the zip file.
so on your pc open up the zip, and extract boot.img to the adb folder
then reboot your device into bootloader and do
fastboot flash boot boot.img

tried first installing rom then boot.img and vice versa but still nothing works.
Is there some other way that will work?
I don't know why but it never install rom, it says that installation is complete, but it's not.
Did i just waste money for that phone?
