Recovery hotkey - LG Optimus Black

Hi, dont call me a lazy person for not searching, because i did and didnt find, but can anybody tell me a hotkey combination to enter recovery, the latest-non touch version? I have currently no ROM installed i wanted to install a nightly upgrade but after a wipe an error occured and the phone rebooted into bootlooping. Thanks in advance.

So you had cm10 installed? If yes push power + volume down and hold it. Otherwise use smartflash to unbrick. Only kernel 3.0.8 includes this reboot to recovery option. Older ones dont have it...

thats the problem i had CM10 installed but does it have anybody to do with it since i wiped my phone? im trying the power+volume down method but doesnt seem to work...downloading smartflash
just for sure do I press them simultaneously or one by one?
thanks for the quick answer by the way :good:

Plug in your charger and when you come to the charging screen hold vol- and power. (or maby on lg logo works to)
If you can't come to the charging screen use smartflashtool.

ok i seem to have a problem here. i use smartflashtool and everything works ok i enter recovery and install supeuser but my phone keeps looping, any idea?

i want to go back to ginger yoshi from cm7

hi.. im currently using CM7 on my G1 and i tried to switch back to gingeryoshi. i've successfully install it but after i install it and reboot my phone. my phone always rebooting to recovery. what ive done wrong? i still have the RADIO-2.22.28.25 and hboot-1.33.0013d. how i can go back to yoshi ????
thanks in advance
strange, to get into recovery you must hold down the home key as you power on, this sounds as simple as a stuck home key. but thats unlikely if you have been using your phone without any issue until now (im assuming this)
what recovery do you have and what method did you take to get back to gingeryoshi

... or the phone boots to recovery due to an invalid / non existing boot image.
Edit: ... or the reboot to recovery flag is set in the misc partition and is not reset correctly.

i have ClockworkMod Recovery v2.5.0.7 and i use the common method.
wipe data/factory reset and wipe cache partition and then install the rom. at the 2nd attempt i wipe also the dalvik cache and at the 3rd attempt i use ohsaka-superwipe. but it all the same. after installing, it reboot to recovery. i don't know what the problem is. because i've already tried to install froyo by laszlo and even the AOSP 4.0.1 Alpha 2. but i get no problem going back to yoshi after trying those rom and i use the same recoverymod. and yeah i don't have any button problem at my phone. and here im using my phone again with CM7 because i can't go back to GingerYoshi. so i just install cm7 again. and i got no problem
it sounds like you are doing everything right. best guess is that you have a bad gingeryoshi update.zip - try going to the thread and downloading again gingeryoshi, then reinstall this to your phone.

Phone always boots in recovery

I was trying to restore my phone to previous state using Rom Manager. Phone restarted in recovery mode, formatted the boot partition and failed to restore. I applied existing of CWM ROM update.zip and snce then my phone restarts in Recovery mode everytime.
I tried one click restore using ODIN, Heimdall nothing worked. recreated the partitions wiped everything, loaded stock ROM but still the phone boots up in recovery mode.
Please suggest some pointers on how to troubleshoot this problem.

do you mean the one click for installing stock rom or something else?
I had the same problem a few days ago couldn't figure it Out. searched and searched for the right image
Files for my Nexsus S. I ended up wiping everything and flashed all the image files with TRWP cause CWR wouldn't work
for the stock ICS and and it worked fine. Now I'm running the 4.1.1 jellybean it sweet.Hope this helps.

Yes the one click package for installing Stock ROM. it did repartitioning, wiped all data, loaded everything successfully. but after booting it shows up the recovery screen.

Hmmm... i've heard of cases where the power button on the captivate refuses to be 'unpressed' which makes it boots up just by plugging in the battery,
Maybe it's like that with your volume buttons?
Does it feels a little bit weird like it doesn't click when you press it?

Thats a good point...
The buttons seem to be normal. I tried keytest and the results look fine
Volume Up : 115
Volume Down : 114
Power : 116
Menu : 139
Home : 102
Search : 217
Back : 158
Moreover I can access recovery and flash any ROM that I have on SDCard. Funny part whenever I flash a new ROM I see a new recovery
Do you know of anyway use ADB without booting phone and putting it in debugging mode?
Thanks for your inputs.
Update: Issue is resolved
I'm not sure on exactly what worked. Using System Corps Recovery, I changed all the partitions to ext4. Made some random changes to toggles during boot. Restarted in download mode and flashed a one click stock rom from http://forum.xda-developers.com/showpost.php?p=18370912&postcount=3
it booted in recovery, then clicked on Flash Bootloader in one click and restarted the phone in download mode and flashed it again with the same ROM.
Thats it. I feel that Bootloader did the trick, but I had it flashed earlier as well.
Thanks irfarf & Sammyazel for your inputs on this.

congrats!!
i do also think that it was the boot loader is the problem here
i had a few problem with my friends cappy won't go into download mode and whenever it boots up, it shows a bunch of random colors than a boot image. turns out that the last bootloader flash wasn't done correctly or something.
Confirmed - the problem is with the bootloader. Once I flashed an original firmware from Samsung, I was then able to install CWM and any ROM I wish after that. Not sure what caused the problem, but this was the solution in my case. Thanks to everyone who pointed me in the right direction!!!

Try running the keytest from recovery mode to ensure all the keys are working fine.
In my case it was corrupt bootloader that caused this issue. you can try flashing stock ROM with bootloaders to fix it.
All the best!
i have same problem. buttons work ok after key test.
how can i reinstall the bootloader?

What exactly did you do to get to this point?
You can find Odin KK4 with bootloaders here: http://forum.xda-developers.com/showpost.php?p=18370912&postcount=3
You will need to flash corn kernel with Odin 1.85 afterwards if you wanna flash a custom ROM.

No, he isn't bricked yet. He just stuck at ANDROID text. So maybe half-bricked. If he can enter Recovery Mode then you are in good luck. If he can't then bad luck, but if he can enter Download Mode, then lucky come to you ! (then if he can't, congrats... you have a trashed phone.)

Agreed. If you can enter recovery and/or download, just go and reflash another rom or the stock rom through CWM or ODIN.
Maybe one click unroot?

oh my, that's a big problem... go to recovery, wipe data, cache and dalvik cache, then format system, flash rom again, and reboot...
Lol...don't be afraid nothing has happened ...since it uses aroma installer you should not wipe data before flashing miui...
Here is what you can do...
Flash a new rom may cm7 or anyother (not miui) ...then again boot into recovery and flash miui without wiping data ...afaik you will be ok...

[Q] Optimus black bootloop

hello!
i'm quite new here and i would gladly appreciate if anybody could redirect me to an existing thread (if any) regarding my concern.
i have my phone installed with rom manager via google play.i made a rom backup as recommended before downloading the recommended cyanogenmod version for my phone. i followed all the instruction about the rom, devlik, cache etc. everything was going well, when suddenly during clockworkmode (forgive my spelling), my phone booted and i thought it successfully installed. but then i noticed that it was booting was continuous even after 10 mins and more. i panicked and i removed the battery. and then i tried the lg shortcut for recovery (i think) which then appear. i chose to restore backup and then reboot. but nothing happened. it still "booting". everytime i power on my phone, it only show the lg logo and the blinking shortcuts. i tried to vol+/- and power but to no avail. i cant go back to the recovery panel. what should i do? :'(
i would kindly appreciate any help you could extend to me.
thank you in advance!
Hello mitzibelle,
Looks like your backup is no good also....
Did you press any keys during the backup procedure? Because backup will stop and not finish if that happened resulting in a unfinished & unusable backup.
What you can do is download the rom you want to install again, to make sure the file is ok check the md5.
Copy this file to your sd card, reboot into recovery and choose install from sd. Browse to the zip file and install.
This should result in a working phone.
Let me know if it was useful or not.

I can't seem to reboot my phone into recovery because the volume+/- and power button combination has no effect. if i put a new rom in the sd card and placed in again in the phone, will the hardware buttons work again? is having a "defective" backup rom affecting the recovery button shortcut or is it a different problem?
thank you for your help
You should be able to enter clockworkmod recovery by pressing the G button below the volume buttons. As soon as the 4 buttons staft to flash. Or just turn it off and on again and start bashing the G key immediately.
As soon as you enter cmw you might also try to flash your previously downloaded file again. Worked for me a few times.
A defective backup does not have any influence on the hardware buttons, also placing a downloaded rom on the sd would not affect the buttons.
Don't forget to clear the caches before you install your downloaded rom if it's different then the one you used when the phone was still working..... Maybe it's wise to clean the caches anyways concerning your previous problems. Wipe factory, cache & dalvik cache also. Dalvik cache can be found under the advanced menu option.
Hope this is useful

If you can't go into recovery you have to do emergency recovery with Smart Flash Tool.
Pressing the G-key repeatedly on boot to go into recovery is only if it has Huexxs G-recovery.

I have to flash it twice because i forget to clear cache, delvik, and restore factory setting.
i hope my battery would not die very quickly (i usually have a battery life of 12 hours on standby with minimal texting) and hope to not encounter any probs in the next few days.

The problem is that I can not connect the phone so I cannot flash the KDZ, do you have a good tutorial how I can flash it?
Have you already got CWM installed on your phone? If you have you need to do power on and volume up, not volume down so put a ROM on the SD card first, full wipe and flash a new ROM and gapps.. If that doesn't work then you need to try get adb access, and run commands such as adb reboot recovery etc, otherwise you need to reflash the .kdz of stock, if you search you'll find it!

@memo357 did you try holding Volume down while plugging into the PC? See if it will light up and show new devices on PC, then start searching here and you'll figure it out. If nothing happens, you're in too deep I'm afraid..

Volume UP still works to boot to recovery, just tried it now, its not misinfo ^.^
If your bootlooping maybe you could use adb to reboot to recovery!
I had this problem. I had to flash the stock boot loader on. Google search should have an lg exe for it. And instructions. I found it pretty easy and once back it should work. You will have to root again and just make sure you unlock your bootloader before applying a custom recover. The exe is called LG mobile support tool, the exe to restore the bootloader.
