[Q] Only bootloop and sw update mode - LG Optimus Black

I bought a Optimus Black and i wanted to delete old account, so i reseted all phone options in settings. After that phone turned off for 5 seconds and turned on with LG logo and flashing keys. And it's not end. The only thing i can do is turn to SW Uptade Mode, when i pushing Volume up button and connect with USB to my computer. SmartFlashTool didn't work, B2CAppSetup.exe don't want install. Can I do anything else? Is it BootLoader broken?

i dont know what is B2CAppSetup.exe but if you want to run smart flash, you should install usb drivers first.
Look this page for drivers. http://www.lg.com/tr/telefon-destegi/lg-P970-LG-Optimus-Black

sorry, B2CAppSetup.exe is LGMobile Support Tool. I have USB drivers, and Smart Flash worked corretly (i think, there is a text on green background "... completed" at the end), but phone reseted and still have a bootloop.

you flashed cwm integrated bin file?
if so, after opening cwm, did you make wipe data?
if you didnt, it will bootlop

I did everything according to the tutorial http://forum.xda-developers.com/showthread.php?t=1448803 and i can't open the cmw.

try this
it is cwm integrated bin and fls files
flash with smart flash tool
after flash, cwm opens automaticaly
after that choose wipe data
and reboot phone

Please I dont wanna make fun of you, but I already saw it once on another forum.So please make sure to have a P970 and not any other phone. Otherwise you ll never be able to recover, if you use the wrong files

i'm sure i have i LG P970

If it still doesn't work after flashing with Smart Flash Tool then take it into repair shop. It's a hardware problem.

[Q] Help. Thrill wont boot (at&t logo), messed up pretty good

1. Rooted
2. Don't think I had USB Debugging on prior to this situation
3. Didn't flash a rom (dont even know how)
4. don't have clockworkmod
I installed the root required app LCD density changer by beansoft... tried permanently changing my lcd density (resolution) to 200, looked back at phone several minutes later and it was stuck on the at&t logo. I didn't do a backup like they said, in case anything goes wrong (didn't expect anything to go wrong.........). Now, everytime I try to boot my phone, i get stuck at the At&t logo screen (NOT infinite loop... just frozen logo). I have tried factory reset multiple times... but ofcourse that didn't work because that doesn't affect system preferences ( like the density/resolution).
Beansoft suggests this to fix the issue... but i can't get it to work
densitychanger.blogspot.(com) (towards the bottom, where the highlighted green text is)...
How can i get that file onto my phone's memory? My phone wont even turn on. I tried putting it on the microsd card, but the file doesnt show up in recovery.
Someone please help me... I just want my phone working again... By whatever means... Flashing a new rom, the update.zip method by beansoft... idk ... just want it working...
HELP :'(
P.S. I dunno how to work adb... every time i try and use it, i get the "device not found" thing... ( i have the drivers installed)... So if that's how I have to fix my phone... PLEASE be very descriptive in instructions....

the 200 dpi setting does not work on the Thrill, which is why you are stuck in "bootloop"

Well looks like you're kinda screwed since you don't have clockwork installed, I'm not sure if you can install a new ROM... but have you tried EVERYTHING in android recovery?
If you don't know how to get to recovery... it's Hold down volume key + 3d + power, until it vibrates then use arrow keys to move around and 3d to select if you dont have clockwork...

Do you havet the emergency mode like most LG smartphones?Here is how you check pull out the battery and the plug it in(so your phone turns off) and then hold down the volume up +voulume down and power button if it worked you should see a yellow screen and a "Emergency mode!!" title.Then google for a kdz update tool and a kdz firmware for YOUR phone.You will also need the LG mobile united drivers.If you are on windows go to control panel and disable the lg modem.Then connect your phone(in emergency mode) to the computer open the update tool then click on select KDZ and navigate to your KDZ then in phone mode select emergency_something iys the only one.Than click flash KDZ and after about 5min your phone should reboot and it wilk work.Its importiant to note that you will lose everything on your phones memory its like you flash a rom you start out fresh you also loose root.Good luck!

About the ADB it shows "device not found" because you didn't enable usb debugging.

Im having the same problem as the person before me, but my phone is stuck on the lg logo screen. My phone is rooted and I do believe I have installed clockworkmod when root manager asked me to. My phone froze on me while going through the root manager app, when I tried formatting it through the reboot screen I ended up with E: can't mount CACHE:recovery/ command, E: can't mount CACHE:recovery/log, and E: can't open CACHE:recovery/log.
I've tried following instuctions from this site: http://www.lg-phones.org/how-to-flash-lg-thrill-4g-to-android-2-3-gingerbread.html
Until the last one cause i don't have an option to instal stuff from my sd card
I've also tried this one: http://http://forum.xda-developers.com/showthread.php?t=1270832
but again I have no option of the sd card or running abd commands
only options i have are:
reboot system now
wipe data/factory reset
wipe cache partition
wipe cache partition and package recovery
wipe nv dynamic partition

You don't have clockwork then.That is your stock recovery.I had this problem too.I flashed the wrong recovery and i got stuck on the LG logo.I fixed it using fastboot flasher idk is it the same combination but on my phone it is volume up+call+power button.Uf it is correct you should see a sign saying fastboot mode udc_start or something like that then use the fastboot flasher to flash a recovery image for your phone.After the flash is complete reboot your phone but first do a NORMAL boot so you can see if the problem is solved.If it worked then you can safely boot into recovery.

Thank you for your support guys, but as it was to difficult, I just got a new one from at&t
I am in similar situation but I am rooted AND I have CWM on my phone. I can boot into recovery just fine and install from sd card and all that jazz but when I try to boot normally I don't get past the LG logo. It just hangs there forever. Do I just have to get a flashable ROM onto the SD card and boot into recovery and flash??
I have already tried wiping data, cache and dalvik to no avail.
Any suggestions??

I rooted phone, everything fine. I flashed CWM, everything fine. When I rebooted system from CWM then phone booted but hung at the LG logo. Now only thing I can do is boot into recovery or boot to the LG logo for hours... Don't even know how this could have happened as I haven't flashed anything, just root and CWM...

lg p970 problem flashing,reset

i messed up my lg with installing ICS,now when i turn on the mob everything is blocked,picture of android is v10 and version inside is v30,i can charge it and i can get in s/w update mode. i tried smartflash but it goes to download complete but mob. wont reboot just turns on lg logo,i tried kdz updater but when i press upgrade start and normally its supposed to ask me which country to choose so i can put different country in my case it goes automaticlly to update. i have teamviewer 8 if maybe someone has time to help me so i dont have to take it to service(no money). thanks
now in lgmobile tool i did phone recovery and after i turn lg on on version it sais v10a and it sais i can start update to gingerbread and when i start on update on 15% it stops,any help?
after error i put manually in s/w update mode and it went all the way,it sais gingerbread installed but cell want reboot and when i turn it on there is no change.
on 90% of update on cell comes lg sign and stayes like that
hey man sorry for the late, I'm a little busy
just a question, when you flash a patched firmware, can you access to the recovery ? if yes, that's all, from there just do a wipe of datas (flash superuser if root is needed) and reboot. done.
no problem its never late, unfortunately not,thats was i am trying to do,i know i need to come to recovery but so far i didnt manage
which firmware did you try ? (give a link if possible)
unfortunately i am at work but i dowloaded v10a from, http://lg-phone-firmware.com/index.php?id_mod=1
these from that site are not patched, but stock...
download this (run to extract binaries) and follow my pdf guide if you have already the upk package
edit : or follow this online guide
ok i will try with this,can you just tell me will i try with kdz updater or with smartflash?
smartflash of course.
kdzu is obsolete since LG has restricted this method (there is a way though, but more complicated)
i have upk ofcourse,i tried so many combinations,maybe i tried even v20s patched but i will give it a go tonight after 10 p.m. when i get home and i will post results,thanks for now Ilko
Ilko this stock v30 recovery,would that maybe help in my case?
If you need a reset, it won't help,because as said before, ICS stock firmwares don't have recovery
From my funky phone
here i am,i tried,download went ok but cell is stuck on lg logo
with vbscript i managed to run r&dtt and change country to diferrent but on 90% always cuts me off,i noticed in device manager that it cuts usb connection,i know that i must put cell on usb debbuging mode but i cant when my cell is completely locked when its turned on,is there any solution for this or we can say i can through it away??
well, I don't know what to say friend. if smartflash fails, other ways will fail too. you may try r&dtt with the shttp tip. I'm afraid this is the last chance
Hmmm, what if he tries to flash a stock ICS? Since SFT tries to reboot in recovery mode, it will wipe data, and maybe will help...
As long as it doesn't drop the usb connection, of course
Sent from my LG-P970 using Tapatalk 2
i used v30b and sft download complete and it turned on lg logo and stays like that,no reboot, with shttp tip i tryed again but it always cuts me out on 90 %, do you guys know if i take it to a special shop for mobile they could reset it with some special cable or something????
when download on smartflash completes usb immediately disconects me and than cell can not reboot,smartflash automaticlly finds a com port,do i need to do something manually with installing drivers or something?????

Really (I mean *really*!) bricked my phone. Nothing works.

Hi p970ies,
EDIT: NEW problems, see last pages.
here is my story:
I was on IZS v1.1, when I decided to go into recovery and make a full-wipe for having a "fresh install" again. You know, the phone was laggy, I had to many apps etc. I pressed the on/off-button for 1-2 secs to reboot into recovery, then my phone turned off and restarted but just with a "bright" black screen, the display was on. I thought "something went wrong", pulled the battery out and put it back in again, started, but then same screen again.
A few months ago an easy "unbricking" method (I know, not really unbricking) was to flash Redy2006's touch-recovery and boot into it with his scripts. So I flashed it (I know it's dumb, because of the u-boot and v30 thing, Idk), same result.
After that, I grabbed smartflash and two .bin/.fls packs of 2 roms, went into that special mode (phone off, press vol+, plug in) but there was no "sign" (screen that shows that you are in that mode) like the other day, the screen kept being black, but on.
Nonetheless the flashing worked and the software said everything alright. I started the phone but same result, in addition that there was now this effect: When the battery is put in and/or the phone is charging, the screen changes from being on and off. I can't do anything, no restarting with buttons, no LG screen, nothing but on and off, on and off. Every few seconds.
Thank you, I hope you experts can help me. (Even when I have the phone 2 years now and I was a ROM-junkie since the first day )
Edit: Tried smartflash with another patched v20 ROM. Tried KDZ Updater, just errors. But now the phone seems to boot, but there's nothing on the display, just the 4 softkeys are fading in and out.

Oh man, its sad to hear that.
I can just think on two situations.
One is a broken screen, but thats pretty obvious.
And the other is a broken boot partition. Its very strange that you cant get into software upgrade mode. You sure you removed SIM, battery and SD, and then plugged it to the cable while holding the volume buttons?
I dont doubt you did it well, just making sure. Anyways AFAIK you should be able to enter that mode unless you got a broken boot partition.
Best of luck, sorry Im not of much help.

Hi, thank you for your answer.
Yesterday oder so, I connected my phone without SIM, SD and battery while pressing vol+ to my pc and it showed the S/W-Update "Wait while update is in progress" or something. I was happy because the display isn't broken. But then I flashed again and the display is as black as before...
I thought about a broken bootloader. Do you guys know a way to fix it? Or the boot partition?

Im pretty sure that if you can see the software update mode, you can unbrick the device.
When you said you reflashed something, do you actually mean that you smartflashed the fls and bin files from a stock v20 rom? AFAIK the bin file carries a bootloader with it so it should get fixed if your problem is the bootloader.
And by the way, while the phone has that black screen and is stuck booting... Are you able to use adb commands? You could try to jump to the recovery with "adb reboot recovery" to see if you got a working recovery.
Best of luck, tell me how it goes

yep, I tried every version (10, 20, 30) in bin/fls and kdz. But I never got the screen to show something again.
And no, I can't use adb commands, sadly. It says "cannot find device" or something like that.

Huhmmm... Quite strange.
You can try to open up device manager, look for the phone (will probably have no drivers and the icon will have a yellow triangle) and force installing adb drivers. After that you are supposed to use adb even in middle of a boot.
I'd say that your best chance is to get to your recovery, so you can wipe everything (even formatting system) and start from scratch...
Anyways Im no expert at all... Just trying to help.

Sometimes ADB works, but it says "device offline". When I flashed PRE-IZS fls/bin from the spanish forum, and then V30B bin/fls, something really weird happens: The phone is on, the wake-button works well - it turns on and turns off the display and the softkeys. But the screen doesn't show anything - just black.
Hello there!
Did You try out the B2C tool provided by LG? And there is one other tool provided by LG. Just try these oit. If they dont work, then try claiming it under warranty. They might replace the motherboard.
P.S: If You have the money, sell this piece of **** and get a Sony or Samsung. Cheers!

Hello there!
Did You try out the B2C tool provided by LG? And there is one other tool provided by LG. Just try these oit. If they dont work, then try claiming it under warranty. They might replace the motherboard.
P.S: If You have the money, sell this piece of **** and get a Sony or Samsung. Cheers!

I think I'm going to buy a Nexus 4, but I have to convince my parents
Oh and yes, phone is older than 2 years and in Germany we only have 2 years of warranty I think.

Sometimes ADB works, but it says "device offline". When I flashed PRE-IZS fls/bin from the spanish forum, and then V30B bin/fls, something really weird happens: The phone is on, the wake-button works well - it turns on and turns off the display and the softkeys. But the screen doesn't show anything - just black.

An easy, possible fix for The Device offline is to use the latest ADB. Just use the attached zip anywhere and use ADB, its the latest version from the android SDK, but just the files required for ADB. My nexus 4 had the same problem, but Solved it by updating ADB.

damn it says "error: device not found" when in S/W or bootloop... or device offline in bootloop
any ideas?
did you try patched bins ? (for being able to boot into recovery right after the flash process, maybe you just need right wipes)
#700th post yay...

Yes, I did, but Smartflash works "less" than the KDZ-Updater. Actually the phone beeped today while it was on (with some kdz flashed) :silly:
Is it possible to convert patched bin/fls files to kdz?
I don't know, probably not... what I can say is that kdzu doesn't perform full wipes since it's intended to update the system and keep datas at the same time. You probably need wipes...

Oh ok... But with KDZ-Updater, it's possible to turn the phone off and on (screens is "on" but shows the color black while the softkeys are on too).
I'll try again with Smartflash... Do you know another version of it or a good tutorial? Maybe I've done the wrong method or something...
there are several tuts in this forum. smartflash is the quickest and safest way to restore / unbrick as it erases everything in the internal memory

I know, but it never works. That problem is so weird! :silly:
Man, nothing works... After smartflashing display flashing off and on again, after kdz display on, softkeys flashing
ADB side service is not active while in S/W mode. The only chance to access to recovery is to boot normally, and access to the device via ADB. The problems are : device needs to pass initial boot process for being able to be detected by ADB (even if you don't see the desktop it's ok), and USB debug must be enabled by default...
so, if you can't pass initial boot process, no chance to use ADB, and, if it passes, usb debug must be enabled or device will remain offline...

Is there a chance to enable it manually?
the only chance is to flash a ROM which have it enabled by default for the most of them.
mine died because of the new twrp 2.6. It has definitively corrupted the boot partition as even smartflash can't ends its process. I had to buy another device...

My phone won't turn on, please help!

Hi everyone
I've LG Optimus 2x and this morning I wanted to install stock rom again on my phone because I had CM. I used smart flash tool (I used it before so I know how to work with him) and everything was OK untill some error poped out. After that I couldn't start my phone, even can't charge it. Screen is black and nothing happens with it. I tried other battery but, same thing. I know that my phone is somehow OK because i can turn it only with flashtool ''progmaq''. I open flash.bat file and that program turns my phone on to S/W upgrade mode but my computer still it does not recognize.
What can I do to start my phone again? I can't use smartflash tool or LG update tool because my computer doesn't recognize my phone. Please help!!!
Same problem as here on this video. I tried to hard reset, can't do it.

Problem solved. I used all in one tool kit and in main menu pressed button 4, followed instruction and I could again access recovery mode, so I installed again rom and now it works.

hello,
is the same thing happened to me yesterday.
You can download the USB drivers from the LG site and install without plug the phone.
Then off the phone, plug phone via usb on pc and turn on it by holding the volume -, it start in download mode.
Then with lg support tool you can do the update online and install it on the phone.
After this update, however, you lose the root and cwm,
I'm trying to find on xda how to root again with v10d....
sorry for my english....
Here also a problem, can't pass twrp... Can't restore any update...
I removed battery, connect with usb cable & hold volume + (if you have installed and opened LG Mobile Support Tool), it will go to download mode and you can reinstal software.
(I edit post if I have more info)
Bingo!! New software version, 10d, no twrp or root
Root and unlock again, flash twrp again -> also be able to restore old back ups (removed original LG back up, so now on new software LG)
Yes, sorry... it was VolumeUp for starting in download mode...
The good news is that root for me works with this guide!!!

Root is also working for me, I also was be able to unlock the bootloader with about.bin for v10b. After that I reflashed twrp and could use my old back up (deleted my old LG back up!).
