Rooting LG Spectrum

**pbolton** · 01-27-2012, 11:20 AM

I have been looking high and low on how to root this phone and have not had any success. Anyone find anything out there. I like this phone and want to keep it but I have to have root.

**k6tcher** · 01-27-2012, 02:35 PM

None of the Gingerbread exploits work. None of the methods for the LG Nitro work. I am returning mine tomorrow morning. I love the phone... just have to have root.

**pbolton** · 01-28-2012, 01:04 PM

I agree I have to have root as well. At the least for backup. Don't know what it will take for some developers or hackers to get their game on. The revolution got some dev love and it was not even near as good as this handset. But I am willing to donate some cash to this endeavor if a Dev comes up with a way to root this hand set. If it were me with these skills I would want to do it just to prove I could and bear them at their own game. I am serious anyone interested can PM me

**k6tcher** · 01-28-2012, 04:56 PM

I returned the Spectrum but I just found this:

Can anyone confirm this working?

**Neph** · 01-28-2012, 05:29 PM

I'm downloading the only firmware I can find being hosted on the LG server. We will see if it is an older version or not.

**DarwinsFolly** · 01-28-2012, 07:24 PM

will be tring this Sunday afternoon. For some reason I think I should e sober for it

**Neph** · 01-28-2012, 07:47 PM

Well, 4.04 is being actively hosted in their repository, but I was able to dig for a link to 3.02. I'm waiting for the file to finish to confirm it is in fact 3.02 and not just a bad archive name.

Sorry to hear you returned it. What you get in its place?

**pbolton** · 01-28-2012, 10:31 PM

Could someone explain what was meant by downgrading. Also how would we accomplish this. I tried it as is now and didnt work. I assume the key has something to do with down grading????

**Neph** · 01-29-2012, 01:26 AM

Downgrading means flashing a version earlier then the 4.04 version that ships with the phone. I was able to find a 3.02 firmware, but the flasher is written in french and I'm not sure if I fully trust it. I will be doing more work on it once I know a Verizon store will be open and I can feign ignorance if something goes catastrophic.

Nothing.

The Razr Maxx is actually a nice looking phone and would serve me well but I cannot downgrade to that screen (ugh!)

Just going to wait and see what quad-cores are coming out. Might be several months before I get a new device now.

**pbolton** · 01-29-2012, 08:50 AM

I figured but wanted to clarify. This is my first LG device. I have had several HTC devices and a few Samsung. I have rooted and used custom ROMS. But as I eluded to I never had owned a LG device and wanted to make sure I understand what they were saying. Please let me know if you get it downgraded and how you did it.

**pbolton** · 01-29-2012, 09:00 AM

Thanks wanted to clarify what was being described. I have owned several HTC and Samsung devices and have rooted them all and most I ran custom ROMS on. This is my first LG device Let me know if your get the device downgraded and how you did it. I really need root so I can get titanium backup on here

yea I tried the Droid Razor and I could not stand it. Motoblur made me think I was downgrading to pre- 2.0 versions of Android. Also for being a Motorola device the signal strength was not that great. Over all the device for what was under the hood was disappointing. At times it lagged and I was also disappointed by the camera. The over usability of the Droid Bonic was much better. Hope the quad core phones come soon. I have a ASUS transformer Prime and love it.

**Shabbypenguin** · 01-29-2012, 10:37 AM

hey guys, just stoppin in to say hi, wanting to know if there was a way to root the phone yet... saw the downgrade method, seems rather sketchy....

**Neph** · 01-29-2012, 12:00 PM

Right now I think it is at a standstill again. I found the lower firmware 3.02

However, all the tools I have tried do not want to find the phone, but the official LG updater works just fine. We may be waiting until the official firmware flasher hits the web. Then again, someone else may have more luck then I have.

**hpchoi411** · 01-31-2012, 12:37 AM

I just posted this,
it works for me!!!!!!!!!!!!!!!!

try it

**Neph** · 01-31-2012, 09:03 AM

I played around with that method this morning for about an hour and could not get it to work. Worse yet, ADB now kicks me out of shell every couple of seconds. I will need to figure out what happened with that. If anyone else gets this working, I would love to know.

**pbolton** · 01-31-2012, 02:32 PM

yea I tried the method hpchoi411 posted over at rootwiki. I also had trouble using his method. Asked him to explain better but didnt get much help. So I am going to wipe my developer box and reinstall Android SDK and ADB etc. Still wanted to know which LG usb driver he used have not gotten an answer yet.

**Neph** · 02-01-2012, 12:31 AM

While wading thru the XDA forums, it seems that a lot of phones released in the last week or so, or that have gotten OTA updates are now immune to Zerg and Gingerbreak. While this sucks that people are losing root, this brings me hope that developers will now focus on finding a new exploit now that the old ones are patched.

**hpchoi411** · 02-01-2012, 10:33 PM

try this method if u can read korean.

**pbolton** · 02-01-2012, 10:38 PM

Sorry my Korean is a little out of practice....lol But appreciate you passing it down. Maybe someone out there does speak it and will translate it for us.

**Neph** · 02-01-2012, 11:40 PM

The page in question is for rooting the Optimus, which we know can be rooted with Zerg rush. From what I can understand of the broken translation, it is as he described it, but it is not a root for the Spectrum.

Also, two things that have come up that may be of use later.

From a fully powered off state (holding the power button until the phone forces itself off)

Down vol + power = factory reset mode

Down vol + Up vol + inserting usb cable while holding both = download mode

**pbolton** · 02-01-2012, 11:50 PM

Yes I had also found the Down vol + power = factory reset mode but had not posted anything about it since it does not do anything for us. But the download mode now that might help us along. Yes I wiped and re setup my development box and that method still did not work but did open an empty word document when it completed...lol Also I was able to root one of my other phones here again with ADB and worked fine. As well as ADB would error with device not found if I did not have the correct LG drivers. So Still looking and playing with it trying to figure a way to get it rooted

**Neph** · 02-02-2012, 01:37 AM

While playing around with one of the KP500 utilities, I was able to get the cab file for the 3.02 version to extract. All it gave me was 3 files.

VS920_WD_1_0_7_0.dll
VS920ZV3_02.S3_02.P58012.R5.wdb
VS920ZV3_02.S3_02.P58012.R5.wdh

No matter what I tried thou, the LG utility refused to flash the phone once the files were extracted, citing a "page error". If any of the above files make sense to you, let me know.

On a similar note, I copied the 3 files and tried to use the KP500 utility to extract the wdb file, but it keep crashing upon trying to extract.
