[Q] LG - P970 bootlooping

Hey guys, i really need some help asap. I really know i will be called a noob for asking this, but i had flashed V20n into my Lg Optimus Black (P970). After i installed Zeus mod on it i got a few bugs, very rarely and some times it wouldnt start. I used to take the battery out for a few hours and everything worked perfect. The last 2 days to it refuses to open. Stays on the LG screen and the buttons flash (has reached CMR screen, i have done a format and then restarted it, and nothing works now AGAIN). I have used easy flasher, trying to install the v20s from 3 different forums but none of them helps. I would really appreciate if i could get some useful fast answers or other link refferals. I have absolutely no personal time within the day, and i will need to know fast in case i need to take it to the service center.

What about smartflashtool, did you try it yet?
If not, download it (use search to find it), then go to my noob how to, download the patched v20s provided in there and then it should work fine again. Dont forget to flash the superuser.zip and do a data, cache, dalvik wipe.

I have tryed it 3 times but with nothing happening. I flashed the AP and the CP file through smartflash :-/ everything in the console succeeds but when it resets target and phone reboots, it wont open. It was just lying there 30 min on the lg sign and the buttons flashing

Try to flash a v10 version. Or try b2c app and emergency recovery.

Are you using touch version of clockworkmod recovery? If yes try to use normal clockworkmod recovery. I have a case before whatever rom i flashed i always ended into bootloop because of the touch version of clockworkmod.

i cant install cwm with the kdz file... i tryed to reflash with smartflash and your patched rom, but stuck into bootloop. Every time i use smartflash i bootloop ... :-/ when i run the kdz file update, everything works great but i canw find a way to flash cwm on it :-/

methods tryed:
i used the method described here: http://forum.xda-developers.com/showthread.php?t=1512203 "FAILED" i have tryed all applications like R&D Test tool, BlackJack etc. But tey all fail... Only one that used to work was the smartflash one, that for some odd reason says it succeses but makes my phone bootloop :-/

Try to flash a very old one like V10A_00.kdz that you can root with GingerBreak-v1.20.apk

[Q] LG990 won't boot.

I installed a rom called Eaglesblood from ROM Manager.
When it was all installed, the phone just loops and won't start. The only thing that is showing is the Eaglesblood logo. I tried to boot ROM Manager, but it wont start since the LG logo is not showing.
Is there anything I can do?
One more thing, I tried to connect it to the computer and it is charing, but it does not show as any device on the computer though.

You must wipe your phone before installing a new rom, otherwise you can get bootloops, try it good luck

search around, there's a few very good guides on this and other forums.

You must reboot in cwm and there you can wipe the phone... in option advanced are mire wipe option, best way to install a custom rom is making a fullwipe.. whatch in xda there are many guides for this.

I tried to access the CWM by holding the Power and -Vol on the phone. The phone just boot up and doesn't even go into the cwm. The Eaglesblood logo just repeats all over.
I can take pictures if you like, if it is easier to understand.
Is there anyway to access the phone by USB? I can't even find it on the PC when I plug it in, it just charges itself

If you are unable to recover your phone you can always use NVflash. It will flash one of the first Froyo versions on your phone. Then you can root it, install ClockworkMod and install any ROM you like.
http://forum.xda-developers.com/showthread.php?t=1007825
It's low level flashing so use it only when there is no other option.

Thanks! But I still have an error trying to connect my phone to the computer. The USB is charing the phone, but the computer won't recognize the device. It doesn't even popup anything.
I have windows 8 on my desktop, and I tried to plug it in the laptop aswell, but it doesn't do anything. And yes, I have the LG drivers installed already.

If you remove battery and you push vol down key and power button and you connect to usb then you get into recovery mode?

No, it doesn't. The LG logo is just flashing then it turns black and repeats itself like that.
However, i tried only to hold down the vol-down button and plugged the USB in and then it starts something saying:
"S/W Upgrade please wait while upgrading..." but it does not show up on the PC as if it was connected.

Yes, so try to reflash cwm.. look at the guids in the section android development..

I'm very thankful for linking me this, but the problem still exist that I can't find my device on Windows. If i remember correctly, the USB connection to the phone stoped to work when I fixed root access to the phone and the CWM.
Is there anything I can do to fix this USB connection issue?

Try this, you can get to the stock via s/w upgrade and smartflash this must work, there is a completr tutorial how to get on stock via smartflash. I hope i can help

Try this exitrecovery.zip. If it works, you phone still may not boot. just flash the zip, reboot; if it doesn't boot re-reboot :laugh: and flash your rom. I would recommend reflashing your rom anyways after fixing the cwm loop issue just to be safe.
If that fails, go through and start the flash. it says phonebook but do it anyways. pick your tot file and let it rip. It will put you into test mode. get the fix here http://forum.xda-developers.com/showthread.php?t=1626198. with the fix, just run it as many times as possible, until it works. You'll know, you will see the usb icons in the status bar. Test mode = no usb icons.

Already have tried the exit recovery

I dont think you can just downgrade with smartflash tools. V30 has a locked ICS bootloader if im correct and apparently my O2X bootlooped when i did that. Now i stuck and even NVFLASH fails

i downgraded my v28g to v20s with smartflash

Thats the answer....
Use Nvflash i downgraded many times from v28a,g,v30a down to v20 or cyanogen mod Its the savest way.
Im form germany... only found the german forum but the zips of nvflash work very well use it:

Anyway although I doubt smartflash could work for my case, I decided to give it try and flash V20B rom (starhub) via the .fls and .bin files method. It gave me an error when it was about to partition the "7 partitions". So i exited and unplug my phone as the SW upgrade screen on my phone turned to a blank screen. I wanted to try again and plug back holding the VOL DOWN button to enter SW mode. I heard the Windows sound notification (when a device is plugged or unplugged) as i do so but the screen was still blank. So i checked the device manager screen and saw that i entered the NVFLASH recovery mode.
Im confused as to how it would work now but anyway i was grateful to your post and that made me give smartflash a try still. :laugh::good:

the easiest way in your situation is using this [TOOL] Full Brick Repair (Clean & Easy)
It's nvflashable and already includes a CM10 nightly. Boot it up and upgrade CM10 with the built in upgrader. That's what I did yesterday. Then boot into recovery and flash gapps.

after reading some information, i solved my question using this thread

thank you all guys that tried to help me.

[SOLVED] - i think swapper bricked My O4X, please help,

hi last night i installed swapper from market and ran it. afterward when i restarted my phone, it got stuck on LG logo. i waited even half hour but it doesn't go any further.
condition is that i can't access adb at lg logo screen, but i can have adb on flashing mod which comes when you press power button + vol up .
secondly it doesn't detect my internal sdcard in default recovery. when i try to access sdcard from adb by cd sdcard, it doesn't go in sdcard. when i try to flash another update.zip from ext-sdcard from default recovery, it says unknown volume for path [/sdcard].
so did swapper deleted my internal sdcard partition or what did it do? what is the solution? i tried to find swapper app from adb, went through folders to folder but i couldn't find it out. may be if i can find it from adb and remove it and also it's created file from sdcard my phone come back to life?
in the last my phone is in warranty. atleast someone show me a way to completely remove rooting from my phone through adb so i can take my phone to their customer center.
i also have lg pc suite and mobile support tool.
i had root access with supersu and i installed cwm recovery in my phone. but since phone is not starting up, i can't go into cwm recovery, i can only go in the default recovery.
please help

bro its ****in up my mind. there are a lot of things on internet, lots of guides, on xda forums there is a post i saw http://forum.xda-developers.com/showthread.php?t=2069723
this post is a tutorial to flash kdz, but i don't know what is my current firmware version, if its 20x or 10x. and how can i see that? coz he says don't downgrade from 20x to 10x with this tool, and i don't know if my is 20x may be? and i might make my problem more complicated by doing wrong things.
please guide me with right path. i'm in trouble and i'm not very experienced in these stuff, i just wanna know things i don't know like i don't know which version of kdz i should download from his link, my country is pakistan and it is not in list of countries over there, and there is european open kdz which is 10a 10b etc. which is for me? your signature says you have 20x, i don't see any 20x over there?
i repeat my situation again.
installed swapper
restarted phone
stuck on LG logo
restarted again n again, no luck
tried adb commands to remove swapper package but can't find sdcard in my root.
tried default recovery, wipe data, wipe cache, restarted, no luck
copied a custonexus rom on my ext-sd, renamed it to update.zip, went to default recovery, tried install update from ext-sd, it gives error "unknown volume for path [/sdcard]"
tried to push update.zip to cache "adb push update.zip /cache", it gives error "permission denied" file system read only.
tried to do these things by connecting my phone to pc while phone is in recovery by removing batteries and inserting, Vol down + power long hold, no luck
tried to do these things while in strange mode lol, removing batteries and inserting, vol up + power long hold. no luck
tried LG support tools, menu > customer support > recovery phone while in strange mode lol vol up + power long hold, it downloads, extracts, and on process of updating it gets stuck on 4%, waited half hour, but no luck
tried the above while going in recovery mode on phone and same options above, but it doesn't connect device.
tried to power on and on LG Logo, same did same above but no luck.
tried to go in S/W mode and do the same above, but it says communication problem, remove batteries and insert and restart update.
now thats all i could do and i know at the moment to do. flashing kdz is new thing for me, im gonna try it but i'm not sure where to start. where to download my kdz and which are right kdz for me.
this is where i need your help. please spare me some time and just tell me and think about what could i do now,
why my phone is stuck on lg logo even internal sdcard is not available, i don't know if it's unmounted by swapper, deleted or formated or partition removed. i can't use adb commands to push coz it's read only, I'm stuck
i can't even take my phone to warranty center coz it's rooted, it has root files in it which will show them it was rooted and warranty will void , even if i delete root files, how can i convince them what did i do with my phone that it's system files are touched and they can't be touched without being rooted.
