Help Please

I rooted my phone and somehow messed it up. I took it to sprint but they told me since I have custom roms they wont be able to help me. The guy at the store pointed me this way. He said something about stuck power cycle on splash screen. I need to get back to the original roms. Before this happen the phone was on android 2.2
Thank you soo much

Best fix, is to ODIN back to stock and start over. If you flashed a ROM, you could try going into CWM and wiping data/cache/dalvik and reflashing...

Go to Development section and follow the thread near the top in the stickies regarding how to fix a semi bricked epic.

With the phone off, press and hold the 1 key on the physical keyboard then add pressing and holding the power button. Yellow triangle saying download mode will pop up. Then you connect the cable to the PC with Odin or Heimdall running.

Soft keys flashing then to CWM 5.8.2 cannot install rom

I'm fairly a noob when it comes to rooting and whatnot, however i've learned quite a bit since i've started. I rooted nexus s with no hassel. My friend the other day gave me a LG Nitro HD, the phone boots shows the LG logo then goes to the Clockworkmod touch 5.8.2. I have tried installing roms on it, it will install the rom and run then when i try to reboot, the soft keys will flash for 2 mins before showing the LG logo and going back to the Clockworkmod again. Keep in mind there is nothing on the SD card besides the signed_HO!NO!_p930 i have tried other os's too. I don't know exactly what he did to his phone. Please help me out. Thanks a bunch guys :laugh:

I know I cannot get into download mode, Will be interested to see if Lugman can or not ... So unbricking is not an option at this point for me. Tried that yesterday also.
Lugman please post any progress sounds though we are in the same river of CWM... Why the HOX is so easy compared to this ....

Try charging it then do a battery pull then plug in the USB while holding the volume update. This should bring up a screen saying download mode. Then unbrick from there.

Are you using the file that is stated in the post you referenced? Im no unbricking expert but Not sure putting verizon firmware on a tmo phone works very well...
Also I had a problem with Odin awhile back and it turned out to be the cable I was using...
If you can get into download mode and have odin recognize your phone I believe you will be good to go if you put the correct software on your phone...
Think you should try to Odin back to a stock firmware for your phone instead of using some sort of "unbrick" method... use only one from this post

Agreed on both accounts.

From an Odin guide I read, can't remember the one now. I believe it said to use the cable from the wall charger. Other cables may work, but that is the one that should work for some reason no matter what.
Good Luck.

If nothing else works on it, search for mobiletechvideos.com. I flashed I-9300 ROM onto my T-999 phone. Hard bricked it. I sent it to those guys and within 1 week, phone was back and was like it was before I flashed the wrong ROM. Great service they provide. It was also my only option. ha.

[Q] Think I bricked...

Bleh just got my Optimus yesterday, came stock with zv9. Decided to root today and had no trouble, flashed TWRP recovery using FreeGee then updated to the newest TWRP version using GooManager. Made a backup using TWRP then used GooManager to download Lifeless ROM. Just downloaded, didn't flash. After the download was done I shut off my Optimus but when I went to restart it, it powered on, showed the LG logo for half a second then just went to a black screen. Can't boot to recovery. Whenever I try and turn the phone off it just restarts again showing the logo for brief period of time then black. Any ideas? It's gotta be bricked but I just don't understand how or why. Probably going to try and take the battery out and see what happens.

okay well your not bricked if you can get even a little life like an LG screen. hook phone up to computer and use adb to get into bootloader and try to reflash the recovery img again. it just sounds like you need to reflash your recovery. thats why it didnt flash. lemme know. ill keep checking back on the thread for awhile

Okay perfect I appreciate it. Downloading SDK right now, I'm away from my desktop and didn't have it on my lappy. LG has a program similar to ODIN too right? Would that maybe work as well?

You would need LGNPST. you can find it in the IRC if you can get to download mode you can flash back to stock and start over.

Yeah that's it thanks. But forgot- can't get in to download mode so that won't work.

I ran the command "adb devices" and the Optimus didn't show up. Is there anything else I can do/try?

Just because the screen doesn't come on don't think the phone is off. Plug that sucker in. If you see the logo you should be able to get in download mode. Also, if the phone is on, you will eventually see some green android screen.
The same thing happened to my phone once. I only know of one way to hard brick this phone. I am not telling anyone how. But, I doubt you did that. It isn't something you would accidentally do.

It's on but it just shows a flat black screen. No matter how long it is on it doesn't get passed that. Also, when it's plugged in there aren't any charging lights. Not sure what to do since adb doesn't recognize it.

I had the same situation a month or two ago. Try leaving it off for 20 minutes and see if it boots back up. Worked for me and like you I had no idea why it did that

If that doesn't work LGNPST again. Factory reset. Then update the profile.

HELP !! Phone doesn't boot past recovery !

Hello guys !
I have done something terrible and phone is not booting up part recovery now.
I had rooted the phone with one-click universal method without any hasstles and then try to reboot into bootloader by pressing VolDown+Power button.
Eventually ended up rebooting in original android recovery. I tried rebooting with option in that but it was not responding.
While trying it out, I mistakenly wiped cache partition.
Now NO MATTER WHAT COMBINATION I TRY, phone doesn't boot up past the recovery.
Please help me sort out this mess. I need to sell the phone.

If you don't mind maybe loosing data, LGNPST back to stock, and try again.

I posted this in the other thread you asked about this in, but here it is:
I wipe my cache partition all the time. I am rooted but still locked (I don't think that will last much longer). Anyways, in the android recovery with jelly bean, I found that you no longer use the power button for selecting or confirming. It's now done using the menu button below your screen (on the right) . At least that's how it works for my phone.
I hope this works for you.

Mate.. after getting the phone booted up I installed FreeGee app from Play store to get bootloader unlocked and flash recovery , but downloading recovery stopped due to an error. So I rebooted the phone and since then Wifi is not detecting my home wifi network.
I then tried to do erase cache partition and even factory reset but nothing helped.
Do u know what else I can do to get it right ?
Cheers !

I haven't fully unlocked my phone yet. Only rooted it. However it sounds like you might have to LGNPST to set things right. Maybe someone else that is more knowledgeable with this issue could chime in and correct me if I'm wrong, but I think that might be your only option.

Thanks mate.. will try this

OK.. mate I tried the LGNPST method. Downloaded LGNPST and stock v9 bin file. Used it to flash the stock rom back to stock.
howvere even after full completion of the process without any errors , the phone stucks at LG logo forever. I have tried the process twice.
Is there something I might have missed. I followed the instruction to the line from the pastebin link. Do we have a different Dll for the stock rom then whats there in the LGNPST repository named LS970_LGNPST.dll or something ?

Hopefully this will get you going.
If you downgraded from ZVB to ZV9 heres some needed info:
If you're stuck at the 4glte screen: To get to stock recovery - Power off phone. You need to hold power button for about 20 sec to get it to turn off. Then press and hold vol down+power - The LG logo will come on, then the capacitive lights. Immediatly let go when the capacitive lights turn on.
It takes a few seconds to work. Data wipe/Factory reset. Reboot.
And if you happen to reboot into recovery after this upgrade? Use the "menu" button on the led lights (far right when holding it) to get it to accept your commands. power button won't work.
---------- Post added at 09:14 AM ---------- Previous post was at 09:08 AM ----------
If that doesn't work try this.
Get into DL mode and run "teeny bin" from the post I sent you to, to get LGNPST. Try the main one first, then the optional one if it still doesn't get you into TWRP. You just might have one of those "haunted phones" that seem to be poping up.

Thanks again mate.. I was able to install Teeny bin and then flashed a AOSP rom. Now I have my wifi working again without any issues.
Do u have a link of any stock based rooted deodexed rom for this ? I don't want to flash bin images via LGNPST but want the stock look and feel

Imperium and Lifeless are our only 2 stock ROMs so far. In the Development section. Both are very nice.
