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.

Thanks a million mate ! I was afraid I'd have to do a factory reset or some long process.

No problem. That's why we are here. To learn and ask questions.

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.
Sorry I'm not of much help for you on this one.

I don't have my bootloader unlocked , so no twrp installed. So can't flash anything.

hold the vol up+down while plugging the phone into the comp instead of pressing the power button. that should work

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.

Cant factory reset my note 3

Hello, I just got my note 3 the other day and I just love it. I just want to be able to get the most out of it that I can. I decided I wanted to root it and put a custom rom on it. I wanted to put the rom wicked because it just looks amazing. Anyways I tried following this tutorial /watch?v=A6qt8sSTKYI (cant post full link) The last step where I had to hold the home, power, and volume up I messed up a bit. I am not sure if it is because I didn't hold them down long enough or what but it didn't work. So when I got back to my phones setting I wanted to factory reset it to start from scratch. When I tried this the phones powers off and then when it powers back on I am stuck in odin mode. The ONLY way I was able to get out of it was taking out the battery for a few secs. Put the battery back in, held down the down volume, home, and power button. Then when that menu came up it said press up to continue or down to cancel or reset. If I pressed up I would be stuck in the odin mode again. When I pressed down the phone then booted fine which was a big relief.
I am just wondering what I did wrong. I really would like to factory restore it before attempting the root again. Maybe this time I can have someone help me on skype? If you are willing to help me that would be wonderful. I will PM you my skype and it will be just through text no voice.
Thank you in advance

I'm just guessing but perhaps you need to just go ahead and flash stock firmware through Odin. Your files or partitions may have got messed up somehow. Its pretty simple. Goto dev section and read up on it. Gonahead and download the files and research while downloading so less wait time.

Thank you, I will try this now. Hopefully this will work for me and not leave me stuck on odin mode again. I just tried to boot into recovery and I still get stuck in odin (cant boot normal). By the way does 0x1 mean I void my warranty? Just curious

Yes, flashing anything will get the ticker to 0x1.(although I heard from some people, you CAN reset it, but it's not solid yet)
Now as far as getting to RECOVERY, it's volume UP, home and power, not down. down is download mode, up is recovery. Hope it helps.
---------- Post added at 08:56 PM ---------- Previous post was at 08:52 PM ----------
also, in order to start anything on a brand new device that not rooted yet, you have to install the root BY going through odin, at that point you should google root note 3 and go to the website(which i cant access im at work) is rootgalaxynote3.com. he has the files you need and tutorials to root, AT THAT POINT install goo manager and install recovery, which you need root access to do. when thats done, you can get into TWRP recovery by holding down in this sequence: volume UP,home,power(always hold down power last to make sure it recognizes you holding down the other two buttons) at that point youre all set to flash!

Yeah that's good. Let us know what happens. That will stock your phone to out of the box. THEN Odin install the root.

Well, That seems to have worked very nicely
After I did what I said above I was able to factory reset without a problem. NOW, before I go ahead and screw up again what procedures should I take exactly? I was having problems when in the videos they where saying clockworkmod. I had the rom manager and then it wanted me to pick a recovery or something and I was confused. Any tips?

Goto the twrp thread and DL 2.6.3.7. Flash that and start flashing.

[Q] :( HEEEEEELP! STUCK AT LG LOGO WHEN I TRY TO BOOT! But wait, there's more......

I have spent the last 3 days searching XDA & trying every possible fix, no luck!
Here's my dilemma.....
I have custom recovery, TWRP 2.6.3.3, don't know what I did after trying to flash something........ I wiped everything except SDcard by accident. Like a darn fool, forgot after backing up everything via computer, to put a spares on my SDcard. Sooooo, I tried restoring by using LG FlashTool..... Here's where my problems began:
1. I can't load into download mode, it sticks at the logo to enter download mode but doesn't connect.
2. I tried ADB Sideload, sticks at "STARTING ADB SIDELOAD FEATURE.........."
3. No matter what mode (including Fastboot) I try, just won't connect to my computer the way I need it to. (*ALL DRIVERS HAVE BEEN REINSTALLED NUMEROUS TIMES, STILL NO LUCK.*) When I look in DEVICE MANAGER, it shows in "OTHER DEVICES" as "LG-LS980" (*Which is a good thing right? *)
At this point i'm at my wits end...... I tried to HARD FACTORY RESET, but didn't go thru. I'm afraid that if I tried it again, I could cause even more damage.
I've been without my phone for days & I'm about to go crazy if I have to pay LG or Sprint again for another phone!!!! I'd rather use my $600 on something else.
PLEASE TELL ME SOMEONE HAS FOUND A WAY TO GET AROUND THIS!
I've searched just about every forum & tried different methods.

Forgot to add that every time I power off from recovery, I get a the message about my device not being rooted, would I like to install..... When I swipe to install, nothing happens. Just powers off.

So try this...
Push the power button to turn the device on. Let it sit.
After you know that the g2 is on and trying to do its think, Press and hold power buttton, do not let go. It will force turn off the phone, but it will start to turn back on, if you keep holding the power button till it shuts off for the second time, you'll be set and the device will be fully off.
Have Lg Flash Tool open, make sure you have manual mode on and you point to the right dll and right tot file, could be zv7 zv8 or zva.
Click the arrow to have the flash tool biin check the files. when that is ready, do this next part fast. Plug in your phone, and immeditaly press and hold Volume up and Power. Download mode should appear.
and you should be good from there! If you try to enter download mode by using volume and up without the cable plug in, you'll hit the factory reset menu which is tied to the recovery, it'll do nothing, only take you to recovery. I hope this is of some help!

Edit:try new boot loader or system flasher via twrp
proplem i faced is one button which used to enter recovery is damged
Flash stock Ignoring the unmonted ianot able to be mounted then change system partitions u will be able to mount
Enjoy

I'm having withdrawal symptoms now. LOL! I MISS MY PHONE!

P605 stuck at recovery booting...need help

So I just tried to flash 4.4 on my P605 (file being P605XXUCNE2_P605OXACNE2_NEE.zip).
Sadly, I forgot to tick 'phone bootloader update' in Odin, soooo....now I'm stuck on the Samsung logo with 'Recovery booting' written in blue on the top left edge.
I've searched the Net for a solution, but all the ones I've found require me to remove my battery, which is kinda impossible on the P605 without hardware modifications.
I really need some help here, as I'm sure there is another way to get to Download Mode.

Flash stock JB rom,let it reboot then Flash Kitkat rom after... Flash TWRP 2.7.0.1 and let reboot, go into recovery, now should be TWRP, flash latest supersu.zip file(1.99r3). Now Kitkat, rooted and custom recovery.
If you don't want root and TWRP, skip those steps...
Just be aware you will have difficulty accessing external sd card with any but stock file manager and not all 3rd party apps will be allowed to use it (unless rooted)...

I had the same problem, just hold down power and down vol and get to into download mode so you can tick that bootloader update and it will work.
Took me a few goes to get it to go there... but it did work for me.. Hope that helps

I also found the flash jig for the S2 works to get to download mode...
Don't know what I mean, here's a youtube video demonstrating, just forget the bit with the battery, you just need to insert and power down - https://www.youtube.com/watch?v=V8yqWf6JU3o
Worth around $3 on ebay... Look for S2 usb jig...

You must do it at the right moment between screen cycles. Took me 1 minute, but for some people here on forum it took 30.

What does a screen cycle mean exactly? Sorry if the question is dumb.
Edit: Just got into d/l mode.
I did that by holding Vol- and power. It restarted a couple of times but in the end it got there. Thanks for all the help.

Try Power + Volume Down + Home instead of just Power + Volume Down, there is a different if you are stuck.

I deleted my Android OS, stuck on LG's logo

Hello to everyone, i hope there is someone could help me
Like i said in the title i deleted my Android OS (yes, i'm an idiot) and now i'm stuck in the LG's logo with the label of unlocked bootloader. I tried to enter in download mode or in TWRP but nothing works...
Do you any advice for me? Thanks and i'm sorry for my bad english

How did you manage to delete your OS? lol.

i wiped all internal data for install a new rom via TWRP but this new rom doesn't exist XD

Okay, so you wiped all data. Then what, you tried to flash new rom via ADB?

just reboot to twrp by holding vol up and power. when you see the lg logo release power and press and hold it again. Then a screen asking to factory reset comes up. say yes and yes, then you are in twrp. Connect phone to computer and enable mtp mode so your computer see the phone. You can then transfer another rom to phone to flash.

Wiping even with internal data checked doesn't wipe twrp...you will have to use button combo to boot as another user suggested...hold vol down+power and when screen comes on release only power then quickly repress power...do not release volume...many people are giving instructions from g2/3 which are slightly different than g4...i have accidentally done this myself...trust me twrp won't overwrite itself it's still there

With phone off. Hold bottom vom down and plug usb connected from pc to phone. That will force download mode. If so, go here http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848

Then you did more than you stated you did because i have erased all in twrp including internal storage and had only to do the button combo to get twrp going and send rom file from pc...retrace your steps and make sure you give as much info as possible and maybe someone can help...but none of the things you mentioned would have touched custom recovery...nevermind it seems you fixed it...enjoy

haha this i have done 3 days after buyed my G4 xD
i was so happy that a KDZ exist... Flashed and well done xD
