First let me say ive used this site many times and never needed to post as all my questions were already answered, so for the many times ive not needed to post thank you all for being so great and helpful!!
That being said im hoping im just using the incorrect rom or going about it wrong. we switched carriers at work and my sprint lgog is sitting in a drawer while my wife uses a droid 4 on a regional carrier because they cant flash phones running JB. So for mothers day i thought i would downgrade to ICS and get this phone flashed for her. Thus far ive managed to root, unlock bootloader and fix two softbricks using teenybin's work. The softbricks came after trying to install both LS970ZV9_ODEX_STOCKROOT_1_13 and LS970ZV9_DEODEX_STOCKROOT_1_13 using twrp. I selected backup and wipe before doing both. Is there a different rom i need to use post VZB to install a ICS rom? or are these roms ok im just installing them improperly? TIA
*update* after trying to install the LS970ZV9_02.bin update with lgnpst the phone hung at 85% and upon reboot would hang at the 4glte screen, I tried teenybin unlocker again and the phone wouldnt boot at all. The lg logo would flash and then blank screen...i couldnt seem to toggle the power at all and it wouldnt even charge on wall charger. after 20 mins of frantic "oh #^#$" button pressing i finally got it to go into recovery mode and recovered back to zvb. It seems mostly back to normal now other than the wifi doesnt seem to be on even though it says its on, no emblem in notification area and wont connect to my wifi when told to.
*update2* after doing factory restore i got my wifi working properly. So i then rerooted and then reinstall teenybin with lgnpst i was able to get into twrp and restore my primary backup.... So now i THINK im back to square 1, rooted, unlocked vzb...at least everything seems to be back to normal. 3rd time is the charm which in this case means i think im going to wait to hear from someone more knowledgeable than i before i screw something up i cant fix
4th attemt 4th fail
so i tried to flash LS970ZV9_02, a totally stock unrooted, locked rom i found here on xda...i did a factory reset before booting into twrp, wiped cache and dalvik, loaded the rom and it boot looped....:crying: i dont know what im doing wrong unless these phones just refuse to downgrade....
I suggest you get on the optimus g IRC. They are very helpful. You may need to find the older radios and flash those after you downgrade. LGNPST should work, normally when it reboots at 85% its a good indication that it worked properly. Perhaps you could find a copy of the ls970zv8.bin and try to install that. Good luck.

I have an LG P903, the Optimus 4G LTE from Bell in Canada.
I wanted to see if there were any good custom ROMs for it so I installed CWM using this thread:
http://forum.xda-developers.com/showthread.php?t=1410454
Which worked like a charm.
Then I went on to install Kernelpan1c's 0.3 ROm form here:
http://forum.xda-developers.com/showthread.php?t=1459610
My device proceeded to bootloop. So I intially jsut restored my nandroid backup that I had made, it continued to bootloop so naturally I read through that thread and pretty much all the other threads in the Nitro HD forums to no avail.
I came across this thread:
http://forum.xda-developers.com/showthread.php?t=1412367
So I decided to do that. I tried various ways of working through that thread and read and searched and read and searched, I worked it out trying download mode, flashing various version trying to even be able to go into CWM but I just get the same LG logo boot loop. Ive tried and tried and tried but I can't get past it.
So I've done everything the video says to not be a noob, yet I guess I still am. I desperatley need some help if anyone can help me.
The big thing was flashing SU640 with kdz_fw_upd_en or with uptestex_mod2_marwin.exe wouldnt work no matter what I tried.
Can you try formatting /data manually:
http://forum.xda-developers.com/showpost.php?p=22533342&postcount=235
Then re-install my ROM and see if it boots
If you need more detail than kernelpan1c's post, I put this together for someone else.

Yeah, neither of those work because I'm unable to boot into CWM or have the phone detected and be able to use adb shell.
I just went into the Bell store and told the guys exactly what I did, step by step I even told them it was rooted/screwed around with and they said thats fine, apparently the plan I have actually covers that. So they're sending off to LG to get repaired, they said that if LG refuses to repair it because it's rooted that they'll replace it for me.
However just as a fail safe, I still wanna investigate what happened.
So adb shell wouldn't work for some reason, saying it wouldn't recognize it, however the other two programs and the mobile support tool did. When i botted into recovery (tapped the power button twice and so on) it wouldn't do stock recovery or boot into CWM.
Thanks for the help anyway, but any other ideas?
Ok, so I flashed a MIUI port for the AT&T Note 2, and it was disgusting...it crashed everything, and needless to say I ended up stuck at the boot logo for a long time. FINALLY managed to get it to flash via Odin...so I flashed Stock Rom...and now it's stuck on Samsung logo...Ok..so I go flash CWM...do a wipe and everything, and install CM10.1 via that...stuck at CM logo. I've left each ROM plugged in, stuck on boot screen for over 20-30 minutes each. I'm at a loss of what to do. Could I need to flash a kernel? or am I missing something obvious? The good news, I guess, is with a few steps, I can get into DL mode and use Odin, and I can flash CWM and get into that..but I can't inject anything into my phone so CWM can use it, I only have what's there now, which is CM10.1. I'm so mad...I've never had too many issues with ROMs but this one jacked things up badly...guess that's what I get for using a port even though it noted that everything was working now. Anyway...does anyone have any advice?
Edit: I flashed CWM, and tried to clear cache/dalvik then factory reset...the first two worked...as soon as I hit factory reset, that's where the screen goes black and it resets...it's like it just refuses to do it. I'm seriously at a loss here. Is it toast?
Edit again: sorry but I'm trying more to give more info. I went into CWM and went to advanced and started formatting one by one...it's when you hit format /data that it immediately dies and restarts. So..something weird is going on there. Can I use a PIT file for this phone, if it exists, to reformat and just get it going? I'm desperate...

Hi,
I have had my lg Optimus G for quite sometime now, almost since it came out. I have had it rooted since day 1 of owning it. We received the JVC firmware update, and i followed the instructions to install and re-root. It was all working just fine, wireless tether, all my root apps, ect. I went to test to see if my boot loader was still installed and i restarted my phone trying to bring up the custom recovery. It brought up the stock recovery menu. The only thing i can do now is go into stock recovery or download mode. It keeps rebooting. I just tried to LNGST but it just simply does the same thing after it reboots, it goes right back to stock recovery menu, or i can get it into download mode if its plugged in. Any suggestions on what i can try next? or is my phone completely pooched. I was using the JVB .bin during LNGST. Please any help you can provide would be awesome, this is my main means of communication.

A factory reset should get you going. You'll probably lose your SD with stock recovery reset though.

Well actually nothing in that menu worked, so i ended up trying teenybins a minute ago the stock zvb and it appears to have fixed my phone. I just reinstalled zvc on it. Im going to reroot and unlock with feegee again, i didnt unlock it last time, maybe thats what the issue was.
So i just Re-installed ZVC, and Re-rooted, and used Free-gee to gain unlock again. I have reboot several times and it looks like im good to go. Hopefully this forum will help people if they ever get the issues i did.
For some reason my phone isn't booting up all the way to the rom/OS. It gets stuck on the boot animation and goes on forever and hasn't been able to boot up since yesterday, when my powered off at 20% battery, which is something normal for my phone. I was rooted and on android 4.3/MK4, but when I put it to charge and tried booting it back up, the phone would boot up, but would get stuck on the boot animation, going on forever. It wouldn't freeze it would just continue to play the animation. I tried removing the battery, factory wiping it, and installing a new rom, which I found out was for a different baseband. When i finished installing it it still wouldn't boot up all the way through.:crying: I then tried installing the previous rom, and still no good. After all that I installed a stock firmware using odin, hoping it would work. I installed the 4.4.2 NE2 firmware, which isn't for my phone but watching zedomax's video, he said to download the latest build date, which is what I did. Well, downloaded it and flashed it through Odin with a PASS and everything going good. Although, when it was rebooting-even after a factory and cache wipe-it still wouldn't boot up. I tried installing other firmwares aswell, but still no luck. I'm just waiting for it to finally boot up, so if anyone can help me out, I WOULD GREATLY APPRECIATE IT, otherwise, anything is going to help at this point. Since I flashed the firmware, I now have a stock recovery and rom(I hope). I've been through these types of situations, but not to this point.. :crying:
It seems odds, but you may want to try a new battery. I recently went through a total disaster with my device and it ultimately was the battery. You may want to try booting with it connected to the a/c wall charger. It may give you an indication.
Have you tried the quick fix posted? My phone did the same thing when i had the stock recovery it showed error mounting efs folder. I noticed after installing clockwork that error didnt show up. It was still the same problem though. Wouldnt hurt to check it out. I got my note two from a friend who described the issue starting the same way you said happend to yours. The phone had never been rooted though. Good luck to you in trying to fix it.

I tried restoring back to factory after being stuck in a boot loop, thinking my root was the issue or something idk. I used flash tool to try and flash back to stock and fac reset and it gets to the end where MiniOS tries to do its thing but i get no promts and it just says factory reset status 2. its driving me insane trying to get this thing flashed back to stock. i dunno if im missing anything or something but im foloowing the steps like to the letter and it keeps bricking. any help or advice here that could help me out? and sorry if this doesnt go here and stuff. im new to the forums and all that.
Hi,
I had the same problem yesterday. Even worse after that factory reset status 2 my phone couldn't be detected anymore by flashtool 1.8. So I tried the kdz method. This worked for me and from stock I was able to use one click root and flash twrp with flashify. Then I went straight to android 8.1 with magisk root. Don't forget to flash mr bump after root without any reboot in between.

yeah i ended up getting it out of status 2 and tried to run stock for a bit but ended up having issues where it would just randomly shut itself off. and then boot loops. switched out like 3 different batteries, (1 that came with the phone, a not so great quality 6000mAh, and a new stock lg battery) and still having boot loop issues. so im thinking that the phone is just dead. so with tax season coming up soon i may just wait and get that new sexy razer phone. i need something new anyway and better than this walmart zte placeholder im using. lol
