Downgrade LG Nitro - Android Software/Hacking General [Developers Only]

First post, and I'm sure you get this alot but I truly am sorry if this is something that's asked 20 times a day. I've spent a good bit of time searching this site and the www but can't seem to find something that addresses this specifically.
I bought a new LG Nitro from att, flashed it to ICS. Now I want to return the phone as I'm still inside my 30 days. I'm assuming I'd be better off putting Gingerbread back on it, but can't figure out how. What's the best way to do this?
Thanks again

Also, if anyone happens to know if At&t doesn't mind accepting returned phones after they've been flashed then let me know! (their return policy doesn't say anything about it)

Did you flash it by Odin or with the official Update Software brought to you by LG?
If you took Odin you really shouldnt send it back to your provider cus they might recognize that you flashed the sw.
You can downgrade your FW:
Download the Gingerbread Stock Rom you want to flash ( search in the internet or in xda )
Flash it via Odin (If you dont know how to do this --> search in the xda )
Hope I could help you =)

SGS bricked! Please help or mom will kill me

Dear Friends,
I happened to have a perfectly working rooted SGS running JPK on Froyo until a while ago. When I tried installing fonts with typefresh. This is where everything went haywire. The phone now doesn't want to boot. It says SGS I9000 and vibrates there 4 times and repeats the vibrating cycle. I want the phone to be working again else my mother will murder me. I tried going to the recovery mode and tried to do a factory restore but that didn't help. Tried to reflash the custom ROM I downloaded from this site (can't find that link) using ODIN but it doesn't work either. While reflashing I did not check the repartition tab. What are the possible solutions here?? KIES doesn't detect phone in download mode. Is there any link from where I can download the factory shipped froyo rom and try reflashing the same via ODIN.
Guys please help it has now turned into a Black Screen Of Death. Though I can still go back to Download mode....please help guys this is getting from bad to worse....
Update: The phone now only goes to download mode...
BUMP! Please guys a few hours before mom comes home from work...
Try flashing a 2.1 firmware with Odin.
Google samfirmware.
Sent from my GT-I5700 using XDA App
You could also try flashing
Froyo that does not brick
and then flash to JI6
EDIT:
Do you have the drivers set up for your device?
Also, What device are you using? The SGS line has many phones. My advice above was dependent on it being a Vibrant
Yes I do have the drivers for my device. I'll be trying 2.1 in a while. What are the chances of Samsung giving me a replacement for the device??
I live in India. We don't get the Vibrant here. It's just plain old Samsung Galaxy S GTi9000

If you can reach download mode, find you favorite firmware in one of the guides on XDA, and using Odin flash it.
If you know what firmware you were on, you can also just reflash the PDA file of that firmware. The PDA file is Packages inside the rar file you download from samfirmware.com
Best thing is to find a guide, and follow it.
I'd JPK before things went haywire. I'm wondering what's the difference between JPK and JPM. Which one should I go for??
I'm planning to flash to JM8 then doing either JPK/JPM. Is this fine?? Or should I directly flash with JPK/M and forget about JM8? Which one is better K or M? Anything else I need to be aware of before I take the plunge??

Hey pal.
It really doesn't matter which firmware you flash. Over the time, I realized that what works for one does not necessarily work for the other. It really is a very subjective thing.
Between JPK and JPM, the later (JPM) is the latest release. If froyo excites you, go for either JPM or even JP6 (JP6 being a day newer than JPM and recommended i suppose). If eclair suits your use, I would suggest JM9
Links:
Eclair - JM9: http://forum.xda-developers.com/showthread.php?t=802909
Froyo - JP6: http://forum.xda-developers.com/showthread.php?t=807351
It really is not difficult flashing firmwares on the i9000. Just follow the instructions from the thread to the dot and you are all set to go. In the same breath, I would also go as far to suggest that you stay away from custom ROM's till you get familiar with the process of flashing ROM's and troubleshooting (in case anything goes wrong). Stick to the stock ROM's and you should be good to begin with.
Do update on your progress.
Cheers.....
Fixed it. Flashed JPK everything working now! Thanks for all the tips and inputs!

2.3.6 help

Hey im still learning things so please cut me some slack. After the update to ICS, my phone basically felt like a paper weight with all the bugs. so i used odin to get me back to 2.3.5 and figured i could use the ota to update to 2.3.6. well ive found out thats hit or miss. today tho it finally went thru and downloaded, however when it rebooted it went into CMW and was unable to install. now as you can figured when i checked for updates again it told me software up to date check back in 24 hours, but my software is still 2.3.5. All im looking for is the original 2.3.6.. does anyone know if i can download it and flash it through CMW somehow? I did find this link http://forum.xda-developers.com/showthread.php?t=1548750 I downloaded the one that says 2.3.6 untouched but when trying to use odin with it, it ****ed up and almost bricked my phone. Is there a noob guide for this? becasue it contained img files along with several tar files. Im just unsure how to do it correctly. Any and all help is greatly appreciated.

[Q] I need LG P925g Stock rom

Hello,
Recently, i have installed CM7 on my LG P925g and all work perfectly.
But i changed my phone for Samsung Galaxy S2 and i give my old phone for my girlfriend. She doesn't like CM7 and i though it will be more easier for her to get back the Stock rom than CM7.
I did a lot research on the web about this and i can't find anything good.
I find some threads...but with dead links.
Do someone can send me a LG P925g Stock rom that i can flash with CWM with a zip. ?
Or a Backup that i can use with CWM ( zip file )
I hope you could help me please...!!

If i remember correctly you can download and install the lg mobile support tool (http://www.lg.com/us/support-mobile/lg-LGP925G scroll down a bit) write down your imei, (settings>about), then pop out the battery hold volume up and plug the usb cable in, aka download mode, the mobile support tool if you have it running and on the screen will try to look at it don't worry about that, Click on the customer support tab, the bottom item recovery phone, this is where your imei comes in, from there type in the IMEI and check, it should find the stock 20c firmware and from there it may need a few more clicks but you'll restore to stock 20c no custom recovery/root, but completely stock 20c.
Hope it helps, worked for me last time i screwed up lol
I justed registered to say thx!
Same problem here, screwed up and didnt know how to establish a working data connection with the pc..
the hint with the download mode really helped a lot, I didnt know that you had do pop out the battery, hold the volume up button and plug in the usb cable..
You can install any custom rom so there are many ROMs which are very stable and it's like the official rom too much not like the CM7 .. but you MUST do a backup before flash any CWM .zip so how cloud you install CM7 with out do a backup ??

[Q] Help - I bricked my phone with latest VZW update

Ok, I have a phone that I purchased used. When my S3 got the Jellybean update in December, I found out it had Clockwork Recovery Mod installed on it. It scared the hell out of me, but I went ahead with the update and it was fine. I am a complete newb to rooting and would never root my phone (I lack the skills). When the update went through in December, I was relieved. For more details on all that, see this thread: http://forum.xda-developers.com/showthread.php?t=2048805
Today's update was a different story. This update appears to have broken my phone.This time, it won't even boot up. It just say "System software not authorized by Verizon Wireless has been found on your phone and go to the nearest Verizon Wireless Store for help." Any suggestions on how to fix this? Am I completely screwed? I have almost no knowledge of rooting, ODIN, etc.
R: [Q] Help - I bricked my phone with latest VZW update
It's not bricked.. you should be able to get in download mode and flash a stock firmware with Odin..

The weirdest thing just happened. Ok, I put in ODIN mode and pressed cancel. Then like 3 minutes later, it just started up all on its own. The update failed of course but the phone is working again. Weird. Was able to turn it off and restart.
I think I may trade this phone back into the same folks who sold it to me. I am clearly not cut out for this.
i'm glad the problem solved by itself
anyway if you still want to attempt to reset the phone to stock here is everything you should need to know :
http://forum.xda-developers.com/showthread.php?t=1762709 (take a look at section 5)
it's really not as hard as it looks...just be aware there is always a chance that something could go wrong....just take your time, read, and only go ahead if you are fully confident and willing to accept the risks...
let us know how it went and don't hesitate to ask for help if you are still in doubt after reading the forum
I hate how I am average Joe with my root knowledge and I could fix your phone without thinking twice.
It surprises me you have an xda account and can not even root and unlock boot loader.
You ask for help then say. Never mind.
Haha whatever works for you at the end of the day.

Installed New update, soft brick. Need an official signed rom

Anyone know of, or or have a link to a factory rom (hell any rom would do at this point) that I would be able to flash with the stock S3 recovery? Just trying to unbrick my phone. Story of what happened below:
I'm running stock 4.1.1 rooted touchwiz. I wake up this morning to a notification saying I had an update on my phone. Should have definitely waited but without thinking I went ahead and updated, which of course soft bricks? The phone. (boots up, and but hangs at the 4Glte, flash screen)normally this would be an easy fix, I could Odin back to stock or something but I'm down in Mississippi till Monday for training and do not have access to my pc.
I can access the factory recovery on the phone but that's it, have no clue where CWM is. I've tried flashing some backups but the factory recovery says that it's not a signed package or whatever. Anyone have any idea how I can get this sucker booted up and running using just an android tablet?
What about reflashing CWM so I can access my backups? Could I somehow flash CWM with factory recovery?:

first of all you can't flash anything on a stock recovery hence the need of a custom recovery. Second you don't accept the OTA when rooted as it can cause the exact issue that you have. Last there isn't a way to fix your problem via another android device that I know of.
U are going to need a pc and then u will need to download Odin http://forum.xda-developers.com/attachment.php?attachmentid=1165122&d=1340993443 and u can get the official software from here on XDA http://hotfile.com/dl/182822657/9f6...WBLK3_381038_REV09_user_low_ship.tar.md5.html this is the 4.1.1 software. Here is a link to some official pre rooted software http://forum.xda-developers.com/showthread.php?t=1984436 all of these software's you can install though Odin just look up here on XDA on how to use Odin and you will be fine once your phone is up and running again then you will need to get you a custom recovery. Then you can access your backups.

He was asking if he can use an android tablet to fix his phone. He doesn't have access to PC at least until Monday it says so in his post. I wasn't even criticizing you at all. Unless he knows someone with a PC in Mississippi or someone here knows how to use one android device to flash something on another android device he sadly will have to wait until he gets home to fix his phone. You didn't do anything to be criticized for trying to help all I did was point out the info that you missed without personally attacking you making it a critique.

hey all, I've been reading , downloading etc for hours trying to get back into my GS3.. i was as usual roaming around and saw a post that said something to this effect "do ya need to get back to stock?" and figured yes i need to so i jumped in with both feet ..i had my boot loader unlocked and for some reason locked the darned thing remembering it was locked before i rooted and then i get the screen that says ie: "System software not authorized ~~~~~~~~~~~~" with a yellow triangle over it with an "!" mark in it..
all would have been ok except the line up of the way to do things was kinda outta line.. after i had locked bootloader "which is the way the GS3 came" i thought. at any rate i am now where i said i was and if i can be helped it would be appreciated.. and no repeated.. next time i'll read their whole line up first.. so help me if ya can and i am game right now for about anything ..
