Thanks for your reply but I remember, not for 100% sure, that I've tried this too. I sort of gave it up after trying so many possibilities and tutorials.

It's so frustrating, I've spend days and even nights on this problem and it made me scared to root my future phones because of this.

I also found a lot of tutorials here very confusing, especially how they are set up with all kinds of different fonts and colors and sizes. For a non english man it is sometimes hard to follow and understand.

I even can't remember how to do this again and I just can't find the need to try it again. But thanks again for your reply!

[Barnes & Noble Nook Tablet] tmjohnsonfse:
I am wondering if anyone else has seen this. I am playing a game - today it was tip off, my battery is at 80% charge, wifi is turned on. During the game my screen suddenly goes black. I can't do anything. Then after several minutes I am able to shut down and restart. Then google services framework will fc and my main screen will be dark for 30 sec. to 1 minute. Then I will see the sd card load and screen will come back on. This is only the second time this has happened and each time I think that I have bricked it. I am not sure if something is getting hot while playing a game, but I would not think that this simple basketball games is intensive enough to cause it to overheat nor is the battery low.

Any thought or tips to what this may be would be appreciated.
[HTC EVO 3D] gregpyro:
Every thread I see is saying you have to unroot to recieve the ota, which is not true. All you have to do is flash the factory recovery and then update . It updates the radios also

[HTC EVO 3D] gmoney23:
Install latest OTA update without re-locking phone

I’m definitely a noob when it comes to this, but I am on HBOOT 1.5 and unlocked my phone via the HTCDev method. But I was able to flash back to the stock recovery, install the OTA update, then flash back to my custom recovery, and flash Superuser again to retain root. Everything worked fine for me.

1.	Made a Nandroid backup (just in case)

2.	Download and rename the zip file above to PG86IMG.zip, then put it on the root of your SD card

3.	Boot into HBoot (this should automatically kick off the installing of the stock recovery zip file)

4.	Reboot phone and let it load normally

5.	Install OTA update

6.	If all goes according to plan and it updates, I remove the PG86IMG.zip off of my SD card

7.	Plug in phone and flash twrp through fastboot (follow this guide here)

8.	Flash su again to retain root

9.	Probably make a Nandroid backup at this point just for fun

10.	Reboot my phone and use it like normal with the lastest OTA update.

Before OTA update:

[HTC EVO 3D] Luda305:
Well i haven't tried to flash recovery the pg86img way. I flashed it through fastboot and flash image gui but I will try your method n see if it works.
[HTC EVO 3D] gmoney23:
It should work through fastboot with the recovery.img as well I think. One note that I forgot to mention is that I'm on the Stock ROM as well (as in, after I originally unlocked my phone, all I did was flash a custom recovery ... I've never flashed a custom ROM).
[HTC EVO 3D] pagandoc:
I have hboot 1.5 to and also not working never installed a custom ROM just custom recovery (was only interested in getting titanium backup working). Guess the above steps only work for 1.4 or less?
[HTC EVO 3D] Luda305:
Just tried your method and still a no go... I'm also on stock rom... After I flash the stock recovery I do the update n it actually starts to install but after the green bar gets a quarter of the way I get the red triangle with the ! In it.... That has happens no matter Wut method I use.... Don't know Wut else to do...
[HTC EVO 3D] gmoney23:
I have hboot 1.5 (and s-on) as well and it worked for me. I was pretty much in the same boat as you with only flashing a custom recovery. Not sure what your problem is. Maybe you could ask a question in the Q&A section and see if you can get some responses.

---------- Post added at 07:29 PM ---------- Previous post was at 07:20 PM ----------

Not sure what your problem is either. Maybe you flashed something or modified some system file so it can't update?
[HTC EVO 3D] Luda305:
As far as I can remember I didn't modify anything but then again maybe I did.... Thanks for the help though.... I'll keep trying n see wut I can do
[HTC EVO 3D] timezone12:
Did you replace your custom recovery with stock one and relock it ?
[HTC EVO 3D] Luda305:
So I have to relock after I flash stock recovery n then reboot n update?

Edit: I got it.... the problem was that I wasn't on the stock kernel.
[HTC EVO 3D] gmoney23:
Glad you got it working Luda. Did you relock your phone to get it to work, or just flash the stock kernel?

And as a note for others, I'm not sure what method timezone12 did, but for me, I did not relock my phone at any point. In review, I flashed the stock recovery, installed the update, then flashed my custom recovery and superuser again. Nothing was lost on my phone, I still have root on hboot 1.5 with s-on, and I have a working OTA update. One quick note that I wanted to mention is that I didn't use the stock recovery found in this thread (I used one from another thread on xda). This shouldn't matter, but I just wanted to make note of it. A lot of people are saying those in my situation need to relock their phone at some point, but I would respectfully disagree.
[HTC EVO 3D] Luda305:
Well I'm not 100% sure it was cuz of the kernel but that's my guess. Wut I did was nandroid back to my stock backup I made right after I did the htcdev unlock thing then I flashed the stock recovery then did the update n all went well. So no need to relock and do the ruu thing that's going around these threads.
[HTC EVO 3D] timezone12:
when you restored the backup did you use fastboot to restore it?
[HTC EVO 3D] Luda305:
Yea I always use fastboot when restoring or flashing roms.
[HTC EVO 3D] theotrman:
Are these steps proven? I'm on hboot 1.5 S-on and I still have my original Nand backup after I 1st rooted my phone.

Can I just restore that?

Then flash stock recovery?

Install update via HTC Updater?

Thank you to anyone that has tested this theory/procedure/protocol.
[HTC EVO 3D] timezone12:
I have done this and works fine here are the steps

1. Backup current Rom

2. Complete wipe

3. Restore backup from original rom

4. Restore stock recovery easiest way use flash image GUI and you do not need to lock the boot loader

5. Take updates 2 if older backup

6. After updates are done install superuser again updates wipe it

7. Reinstall backup from number 1 or fresh install your done
[HTC EVO 3D] gmoney23:
In regards to the naming of the recovery image, yes, it should be named recovery.img. Once it is on your SD card, I would think you should be able to flash it using Clockwork, but I have never done that so you may want to search around for a better answer (I use twrp and just put the PG86IMG.zip and reboot into the bootloader to kick it off).

The part you are missing about using the zip file is that I am already on the stock ROM (which I failed to mention in the original post ... post #10 in this thread explains it though). So, if you have a custom ROM, you may need to install a stock ROM before you try to flash the stock recovery, but I can't verify that since I wasn't in that situation.

Hope this helps some.
[HTC EVO 3D] megabiteg:
I'm also getting the red triangle error when I try to update and I'm fully stock, stock recovery. 1.5hboot unlocked, but I did discover this:

When the red triangle appears if you press power + Vol up (let at least 20 sec pass after the error shows up to do this, you may have to press the combination 1 or 2 times) a description of the error will appear. For me one of the asserts scripts threw a flag on the Flickr.apk, don't know why but it finds an error on that file. Also, apart from displaying the error messages you get it gives you access to the stock recovery menu, which lets you reboot the phone from there :)

Note: upon reboot the update gets erased from the /sdcard/download folder.

EDIT: IF you don't want to reboot your phone back to stock and have to waist time backing up and restoring your phone you need to make sure that you didn't remove any system/app apps because the update will check for them.

EDIT2: After replacing all the files that were missing, update applied successfully.
[HTC EVO 3D] harismahesh:
I have a doubt. After updating, Will i loose root ? and will be the phone on S-ON ?
[HTC EVO 3D] blauciel:
After finally deciding to do this, and finally figuring this out, here's what I found was missing in the steps on page 1 from gmoney23's post:

1.	Made a Nandroid backup (just in case)

2.	Download one of the files that contains some form of recovery.img (e.g. recovery-signed.img)

**MISSING INSTRUCTIONS FOLLOW**

**You need adb working, either set your path to the platform-tools folder in your Android-SDK installation, or have a set of adb.exe and adb. I have this path added to my PATH variable in windows: C:\Program Files (x86)\Android\android-sdk\platform-tools

2a. open a command prompt and enter: "adb reboot bootloader"

--this will reboot your phone into the HBoot bootloader and it will say "FASTBOOT USB"

--step 2b requires that you have one of the stock recovery.img files in this thread.

2b. Now, at the command prompt type "fastboot flash recovery recovery.img"

--this will start loading the recovery image.

3. Verify there are no errors.

***Resume***

4.	Reboot phone and let it load normally

5.	Install OTA update (Menu -> Settings -> Updates -> HTC Software Updates -> Check Now -> Install Now)

6.	If all goes according to plan and it updates, I remove the PG86IMG.zip off of my SD card

7.	Plug in phone and flash twrp through fastboot (follow this guide here)

8.	Flash su again to retain root

9.	Probably make a Nandroid backup at this point just for fun

10.	Reboot my phone and use it like normal with the lastest OTA update.
[HTC EVO 3D] GrimReaper24:
Lol I only tell new folks the best way to take a update is to unroot on the hboot 1.5.. Just to play it safe... I know in the past some new folks tried to update that other way and bricked there phones...

Until they get comfy with root and flashing I tell em to unroot :D
[HTC EVO 3D] ArunOnline:
I have flashed the recovery.img file (which I downloaded as "stock_recover.rar" from the same topic, extracted the "recovery_signed.img" file from it and renamed as "recovery.img" and placed it in the "platform-tools" directory) successfully using the "fastboot flash recovery recovery.img" command on PC and there were no errors. I rebooted the handset after that and checked for update. Note that root was working at this time. When I proceeded to install the available update the handset powered off and then showed the red triangle. Do you know what I did wrong?

[Samsung Galaxy Nexus] GNowner:
Hi guys, it happened that I can still bring back my GN and get another phone. The LG Spectrum will be available on Jan 19. By looking the specs here is what I see:

Processor GN - 1.2, LG 1.5

Camera GN - 5 mp, LG 8 mp

Screen - same resolution, LG has better colors (at least what they're saying).

Storage: GN - 32 gig, LG - 4+.

OS - here is the huge disadvantage: LG has Gingerbread versus ICS on GN. However they claim update will be available early this year.

Also, Verizon will be making LG global and it priced $100 chipper.

Guys, am I missing something? Are there any other reasons to keep GN?

I appreciate your input.
[Samsung Galaxy Nexus] fahren:
Hm, certainly you are missing couple of things.

According to quick search on Google: "(LG Spectrum) won’t get Ice Cream Sandwich until the second half of 2012". This alone kills the phone for me.

Otherwise, it lacks notification LED - one of the main features of SGN for me.

It also has buttons on the front, not soft buttons on the screen like SGN.

If I was in the market for other than SGN android phone, I would either wait for SGS3, or the new Sony Xperia S, or maybe I would just go for the Galaxy Note (ICS update expected in 1-2 months).
[Samsung Galaxy Nexus] zephiK:
Stock Android Experience (esp. on Ice Cream Sandwich) > any manufacturered skin of Android.

Not to mention Nexus devices tend to get a lot of good developer support simply because its a Nexus device.
[Samsung Galaxy Nexus] emuneee:
LG is possibly theeeeee absolute worse at making stable Android software, not to mention their support is lacking, and their skin is horrible. To each his own though.
[Samsung Galaxy Nexus] AdamHart612:
LG is without a doubt the worst phone manufacturer when it comes to system updates. G2x shipped with 2.2, was promised 2.3 within weeks, and didn't receive it officially until 6 months later. Tons of people had quality control issues with 3,4,5 replacements being common. Stay far, far away from LG. G2x was fantastic to hold and was great when it works correctly, but left such a bad taste in my mouth I wont be purchasing LG products again.
[Samsung Galaxy Nexus] mysterioustko:
When talking about processors, there's more to consider than just clock speed. To make a long story short, I'd quickly take the 1.2 OMAP 4460 over a 1.5 snapdragon S3 any day of the week. I refuse to accept a phone using a snapdragon S3.

Camera - Megapixels alone do not make a camera better. That just means it takes larger photos.

Screen - Not sure where you heard it had better colors, but with it having an IPS display that means two things will inherently be true. It will not have anywhere near the same contrast as the Galaxy Nexus and it's color will not be as vibrant. For your reference, some IPS displays are only 800:1 whereas the GNex has a contrast ratio of 100000:1. Needless to say, that's quite a sizeable difference, and visibly the difference is quite ostensible.

OS - LG's reputation with updates is worse than any other manufacturer out there. On the G2x they promised an update to gingerbread in "a few weeks", and that "few weeks" turned into several months. When they do actually update the spectrum to ICS the Galaxy Nexus will be close to getting Jellybean and will already have had multiple incremental updates already. Not to mention that the ICS update will likely be the first and last update the Spectrum will see.

As for things that you might be missing, one the that jumps out at me is the lack of NFC. I refuse to purchase a phone that does not have nfc. NFC is due to really pick up this year, and I'm not the least bit interested in any device that will lack this.

Overall the main reason I wouldn't give this phone a second thought is...

IT'S AN LG PHONE

. That alone is enough reason to give me pause. LG's reputation in the cell phone world is worse than horrid. They make buggy devices and then don't support them. Heck when they finally did update the g2x to gingerbread, they still left it with a froyo kernel! WTF! The fact that this phone is made by LG is enough to make it an object of derision. I would advise you to forego that phone. Friends don't let friends use LG phones.
[Samsung Galaxy Nexus] kendrick16:
Spectrum has the same specs as the LG Nitro for ATT. Horrendous battery life. That's why I returned the Nitro and got the Galaxy Nexus.
[Samsung Galaxy Nexus] Ferradinho:
The Spectrum is thoroughly unimpressive after using it for a few days. Compared to the Nexus it just feels wrong in my hand. I'm afraid to see how diluted ICS is going to be once the manufacturers add their skins on top of them; it will NOT be the same experience that you get on the Nexus.

That being said the great thing about having multiple devices available is there is something to fit the needs of just about anyone. So if that's a better fit for you then go for it...
[Samsung Galaxy Nexus] Ferradinho:
Ha! Well put. I carried the Revolution as my company phone for a while before upgrading to the Rezound and I'll agree, LG Android phones are crap. Also, add stated NFC is something that I wouldn't buy a phone without and there are a lot of things to consider when comparing processors and cameras; clock speed and megapixels are not the only factors.
[Samsung Galaxy Nexus] GNowner:
Thanks to all. I'll stay with GN. I do like my phone. But as always when you see something better at least on paper you start thinking. Several years back I used to have an LG phone (not android). It wasn't that bad.

Anyway, I'm not changing my login to LGowner. GNowner - that is.
