[FAQ][HELP THREAD][Noob Friendly] LG G2 Ask any question

[SIZE=+3]Frequently Asked Questions[/SIZE]
[SIZE=+2]LG G2[/SIZE]​
[SIZE=+1]This a short list of frequently asked questions in this device forum and the answers often given as a response. It should serve as a starting point for gathering knowledge and finding solutions to many common problems. [/SIZE]
[SIZE=+1]Q1: How do I root my G2?[/SIZE]There are several root methods depending on what android version you're on:
IOroot (Jellybean 4.2x/KitKat 4.4x)
New Root Method for LG Devices (Lollipop 5x)
[Japanese L-01F] Root your L-01F [HOWTO]
[SIZE=+1]Q2: How do I restore my phone to stock?[/SIZE]Visit the Back to stock thread. This has detailed instructions on how to flash factory firmware. If you have bricked your device or are trying to fix software issues then this is the go to method.​
[SIZE=+1]Q3: Can I recieve OTA updates while my phone is rooted?[/SIZE]Short answer, no. If you have any modified files at the root level of your device this will break OTA. You may have to flash the stock firmware before you take an update.​
[SIZE=+1]Q4: My phone won't connect to my PC. How do I fix this?[/SIZE]You might be experiencing driver issues. To resolve it take the following steps:
Download the LGUnitedMobile driver here
Open programs and features and delete the currently installed drivers
Launch the exe file of the drivers that you downloaded and let it install
Reboot your PC and try connecting your phone again.
If your still not connecting then try using PDAnet drivers. Again, delete the LG drivers you installed and launch PDAnet on your PC. Let the drivers install and try again.​
[SIZE=+1]Q5: I have a f320/ isai/l-01f . Where is the development for my variant?[/SIZE]These variants aren't as widely supported as the other ones unfortunately. Many ROM devs support the f320 but the ISAI and l-01f don't get as much love. There are dedicated threads for these variants here:
LG isai LGL22 Central Index - TOT&DLL | KDZ | Root | Recovery | ROM | Discussion
AOSP for Japanese G2 L-01F
[SIZE=+1]Q6: Is it possible to sim unlock the Sprint G2?[/SIZE]Yes. See these threads:
Sim Unlock ZVG lollipop
Permanent SIM Unlock for LS980 (OTA, APN) JB 4.2.2, KK 4.4.2
[SIZE=+1]Q7: How do I flash a custom recovery?[/SIZE]If you are coming from stock you need to root your device first (see Q.1). Here are the recovery methods based on android version:
KitKat
Use Autorec from this thread. Pick the correct one for your variant.
Lollipop
Use the Autorec app from the playstore. You can find them here. There is a separate app for each variant so pay close attention to which one you use.
Launch the app and follow the instructions to reboot to recovery.
Jellybean
There are several methods of doing this. Here is the easiest one:
[RECOVERY] [TWRP] [FLASHIFY] Quick & easy​[SIZE=+1]Q8: What is ADB and fastboot?[/SIZE]ADB stands for Android Debug Bridge. These are the android tools developed by Google for developers and users to connect devices to a PC and send commands to it. There's a detailed guide to ADB here.​[SIZE=+1]Q9: What is Bump!!!?[/SIZE]Bump is a bootloader exploit developed by team Codefire. It's purpose (in a nutshell) is to allow KitKat bootloaders to load custom boot (kernel) and recovery images to allow the flashing of custom ROMs.
By bumping a boot.img the tool signs it using it's magic keys to trick the bootloader into thinking that it is, in fact an official boot.img.​[SIZE=+1]Q10: I bricked my phone and it is now in fastboot mode. How do I fix this?[/SIZE]There are several ways to fix it. If you have download mode you can flash a stock image (see Q.2). You can also use the fastboot tools to flash over the damaged partitions (see Q.8).
@somboons has developed a utility called SRK Tools which has a function to fix fastboot mode, and do many other useful things. You can find his tool here.​[SIZE=+1]Q11: I rooted my device and now I need to RMA it. Is there any way to unroot/hide root?[/SIZE]If your device is rooted then there will be a root flag in download mode. This will be there even if you unroot from within superuser.
To remove all traces of root you will need to flash the stock firmware again (see Q.2)​[SIZE=+1]Q12: What is a bootstack and why is it important?[/SIZE]A bootstack is a set of partition images that are needed for android to boot. In the case of the G2 partitions need to be slightly modified because the LP bootloader will not load custom images. In other words, if you want to flash a custom recovery and ROM, you need a KK bootloader and bumped kernel and recovery images. Autorec does this automatically or you can flash your own hybrid bootstack ​[SIZE=+1]Q13: My phone is dead or my PC recognises my phone as QHSUSB_BULK/Qualcomm 9006/8 or security error. How do I fix this?[/SIZE]These errors occur when your device has mismatched/corrupt or missing partitions. This can occur by flashing the wrong ROM, Autorec or bootloader. (eg. nuking your bootloader will give you a security error.) In the case that you still have download mode, you can just flash a stock image to fix it. If your phone is not booting into any mode but it's recognized by your PC then pay attention to device manager to see how windows sees your phone. For QHSUSB_BULK see here and here.
Alternatively you can use the Srk Tools. For qualcomm 9006 see here For Qualcomm 9008 or if your phone is not recognized by PC (windows/mac OR linux) and does not boot then you may need to follow this guide to revive your phone.​[SIZE=+1]Q14: How do I enter recovery with the button combination?[/SIZE]If you have a custom recovery you use the button combination to factory reset.
Power off the device
Hold volume down and power button until you see the LG logo
For JB/KK Hold volume down and power
For LL Hold volume down and volume up
Enter at the factory reset screen
[SIZE=+1]Q15: What is an EFS and why is it important?[/SIZE]Your EFS partition contains some important and some basic info related to our device identity like Bluetooth MAC address, wireless devices MAC addresses, product code and the very main IMEI address, radio settings, programming parameters for the device such as your account information (phone number, etc), data provisioning parameters, etc. An EFS cannot be replaced. It is unique to every device and it is highly recommended that you back it up soon after rooting your device. See this thread for a how to. EFS Partition Backup and More [All G2 Variants​[SIZE=+1]Q16: I updated my phone and now the touch screen is erratic and my IMEI is gone. What is happening?[/SIZE]This scenario is common to G2's that are refurbished with mixed parts of many G2 variants. Typically the vendor has used a motherboard from any random G2 variant and packaged it as a d802. It is fixable however, see this thread for more details on how to identify your model. You must get the real model number which is written on the bottom of the mainboard and then flash a stock image accordingly. Restoring your IMEI is trickier though. It is easy if you have previously taken an EFS backup (see Q.15). You can flash the EFS backup zip or use dd to restore modemst1 and 2.
Without an EFS backup you cannot restore a lost IMEI. There are methods that claim to work and they are worth exploring but there is nothing that is definitely known to restore a lost IMEI.​*​Forum Rules | New Users Guide | XDA Tour | Report Posts​A special thanks to everyone who contributed to the production of this FAQ​

Judgment Came....
There are a lot of people joining xda on daily basis, and there are a lot of repetitive questions being asked which fill up Development threads. Point them here. Feel free to ask or answer questions. Idea of this thread is to get users to help other users with their problems/questions. Please do not spoon feed, but rather point in the direction where that user can find an answer and educate himself
I do have the G2 fortunately, in order to make XDA a better place, I thought I'd open up a help thread for those who need it. I will be able to give lots of help to fellow G2 users. Hopefully some of the experienced G2 users help out on this thread, because it'd make everything easier. Thanks!
First thing first. I strongly advise you to read THIS thread before posting ANYTHING on XDA.
Then, have a quick look at the names of threads in post no2, you might find what you need right away.
For ROM issues please do mention in your post about:
ROM name
ROM version and base
kernel version and its settings
any mods applied on top of it
flashing "style" aka dirty or clean
something like this
...and be sure you have asked before on the ROM thread unless you have less than 10 posts on XDA
Third. The second post will be used to link to threads for some of the most common problems+fixes. You'll be surprised how much time and frustration it will save you in the future.
ASK ANY QUESTION HERE,adb, drivers, superCID, problems, mods etc...... You will either get an answer or will get pointed in the right direction.
No abuse towards noobs tolerated here! No question is stupid in this thread.
***I feel that a little OT is healthy to the success of this type of thread. The people here who help the most will develop a comradery therefore OT is allowed within reason. Common sense will be applied ***

Thanks for this thread and I do need help here.
So I have barely unplugged three in a half hours ago from full charge and I have 79 percent right now. 21 percent drop in three hours. That's a ton.
I have the 12b rom which I manually got since I'm rooted and couldn't update via Verizon. And flashed the pure audio 2 mod but that's it

So you're using a custom rom right? In that case I'd suggest a full wipe then a clean flash followed by flashing PA or Banks gapps. I use those steps on my Nexus 4 and Nexus One (I don't have a G2), but I've never run into any battery issues

Well, I'm no expert at G2 stuff, but if your kitkat rom includes a different radio, then I would suggest that you do flash the jb baseband. Don't mark my words, double check the rom thread just to be sure

g2 framework
is it possible to embed g2 original framework in aosp roms so we can install original g2 apps with no problems?

Hi,
I'm searching for a new phone to buy and this one caught my eye. I have 3 questions.
Is there anything (bad) I should know about the phone before buying it? All the good points are well advertised and easily available to read about on the internet, but the bad things only surface after you used the phone yourself for a while. (No need to mention back buttons though).
Making a custom kernel on non-nexus devices is always a tad (or more) harder, I hear. Are there already (very) stable kernels available like you can expect to see on a nexus device?
Is there any G2 developer looking into/developing Ubuntu Touch for this device? I'm interested in Ubuntu for Android you see, and it'd be awesome if I can use it on this phone like on my gnex.

It's be very hard to accomplish that as porting manufacturer specific stuff is quite difficult.

Wifi Hotspot and other questions
I purchased a Sprint LG G2. It has been rooted and unlocked. Unfortunately, the person I bought it from doesn't know much about the rooting process that was followed and he just followed instructions given to him by a friend. As far as I can tell, there is no custom ROM on the device. Here are my questions:
- At this moment, there is no Wi-Fi Hotspot option on my device. I'm planning to follow the instructions from here: http://forum.xda-developers.com/showthread.php?t=2675280. But this link is for non-activated devices. Question is: How do I know if my phone has or has not been activated?
- If I do decide to follow the instructions in the above link, what would be the best way to backup my device first? Would you recommend Titanium Backup?
- The 3G connection on the phone seems to be awfully slow. Is this a 'Unlocked Spring G2' issue? Is there anything I can do to fix it?
Thank you in advance for all your help.

HELP.. deleted my stock LG camera app
Hello all,
In a quest to improve everything about my phone I seem to have completely deleted my camera app!!! I was attempting to apply the upgrade to the software that can be found here: http://forum.xda-developers.com/showthread.php?t=2471900. I changed the names of the files and permissions exactly as said, rebooted, and poof the camera app was gone. I have since downloaded a third party app to replace it, but I'd like to have the stock app back. No, I did not back up immediately before, I know STUPID!
Any help?? There are great third party apps and I can get by, but thought I'd try.
Thanks!

For what you are seeking, nexus devices will be your best bet. They have the easiest developing because of not needed custom code. I really like the G2, but for me, the kitkat update was a bust (battery wonky, lots of random reboots, audio issues), so I went back to stock rooted JB. Very nice device that is very stable, but I don't care about AOSP, if I did, I would have gotten N5. Almost everything can be done through being rooted and xposed modules these days.

are you rooted, on a custom ROM? If you are on custom ROM you can just reflash ROM without wiping data and it will be added back. If stock, maybe someone can make you an apk you can install or the files can be pushed via adb.

Yea, I am rooted but am stock. I have a stock camera APK but when I try and install it just says "App Not Installed" over and over again. Reset permissions, put in privat_apps folder and no lock. May just have to live with third party... Camera Zoom Fx and Procapture are both good. Thanks!!

You would probably have to push it via adb.
something along the lines of
adb push camera.apk /system/app
chmod 644 /system/app/camera.apk
reboot device
If you have an adb folder, put the camera.apk in the root of it, then run the commands. Should work.
You could also have a look at xdabbeb's camera mod. Might be able to get that to install.

Finally fixed it. Turns out just moving the LGCamera.apk to system/apps instead of priv_apps did the trick. Thanks again for hte help!

Bootloop, nothing works

Hi guys,
So I'm a little lost. After flashing the 01/05 ParanoidAndroid rom for the D802, I got stuck in a bootloop. So I did a hard reset and entered twrp recovery again. There I flashed the other rom which was working before, but also after that I got stuck in a bootloop. Now I don't know what to do anymore.
I already tried to flash the kdz file, but it didn't work.
Can someone please help me out?

You can't flash a kdz only a tot, not tried it yet though. Though I'm in the same situation
There is also mention on the PA page that you need an official LG KK modem image to flash after the ROM & GAPPS: http://forum.xda-developers.com/showthread.php?t=2502789

The first link you proposed worked for me. Very nice Thnx. You should try it also

Yup, I can get into download mode and TWRP, and I've tried to flash what I had (0430) twice, in various ways. No joy. Now I'm going to try sideloading a file via ADB in TWRP, as I'll need gapps and possibly the LG KK modem too. I'm just documenting it all, so I have a complete workup of what worked and what didn't. I'm sure somebody else will find it useful, (as will I) when it inevitably happens again. Luckily I have my old Galaxy S (Omni 4.4.2) that I can jump my SIM into, so I at least have a phone

Video of somebody unbricking a phone: https://www.youtube.com/watch?v=kqw_LFuyHbE AT&T in this case but the same procedure as above for the d802 in general.

After many hours of diligent back and forth last night, I gave in and restored from a backup, my last stop before flashing back to stock. That actually worked. So I'm back to the point of being rooted with TWRP installed, (Seriously, make a backup) but at least I have still have all my data.
I've actually used the stock LG interface for more time now than I did after I picked up the phone. God it's awful. I can understand that as an OEM, you need sales bullet points, and something to fill a product launch with, as such you largely have to add to what exists in stock android. But I doubt they ever did any UX tests, either that, or the focus group they had were all "normals" who've never seen a smartphone before. But I digress..
I spent most of the time getting adb to work again, and experimenting with that. I re-installed the drivers, available at my first link above. After that nothing seemed to work, so I manually found the 64bit USB installer and ran that, still no joy, then rebooted the PC. Once I reconnected the phone, then the installers kicked in, though MPT failed. But all you really need is the ADB interface.
I also found out that "adb devices" only ever sees the phone when it's booted into the system, and stuck at the boot animation after the LG logo. If I booted into TWRP recovery it, even in sideload mode, Nothing worked.
adb is part of the SDK which you can get from here:
http://developer.android.com/sdk/index.html
Though all you need is a couple of binaries and a few dll's, and you can find all that in IORoot25 here:
http://forum.xda-developers.com/showthread.php?p=45692679#post45692679
File: http://bit.ly/1hPLwsj
These are basic guides for adb:

http://www.herongyang.com/Android/adb-push-and-pull-Command.html (push & pull)

http://www.androidcentral.com/android-201-10-basic-terminal-commands-you-should-know (10 cmds)
The adb shell is UNIX, not DOS, just FYI. these have you covered:
http://forum.xda-developers.com/showthread.php?t=502010
http://developer.android.com/tools/help/adb.html#shellcommands
I used it to upload more PA roms, gapps, etc. None of which worked. regardless of how I did it. Dirty or clean, (with the exception of fully wiping data.) I found the most useful functionality was the command, adb reboot recovery, which will drop you directly into TWRP without the need for the Vulcan handshake. Which is often frustrating, a bit hit & miss, at least for me.
I tried to flash 0429, 0430 & 0501, none of them worked, though I was on 0430 when it borked.
Just FYI

I'm just providing stock kernel for 5.1.1 SM-G530AZ
1. Root SM-G530AZ 5.1.1 with kingroot 4.6.2 or higer (kingroot.net)
2. DON'T Reboot
3. Download and install Flashify on play store or APK
4. Flash stock kernel with flashify (http://www.mediafire.com/download/2fk19cadccq0xd7/boot.img)
5. Reboot.
6. Replace kinguser with supersu (optional) (http://www.mediafire.com/download/x1efi7ev6nf3mvd/Replace_Kinguser_with_SuperSU-v2.0.zip)

Awesome, thank you so much. Going to try it right now, but I'm betting it will work. Thank you again for putting this all together.

Nice, think I flashed the wrong boot.img from that thread, there are two different img's, one as tar and the other as img. We actually need the img in the tar, which you have posted above. Thanks for posting this up.

guys thank you very much! i will try this and report results to the forum!

HELP!!

There are a couple things you can do here.
1. Try re-downloading the boot.img and reflashing with flashify
2. Try flashing the boot.img with Odin3
3. Restoring your phone with Kies http://forum.xda-developers.com/showpost.php?p=61977268&postcount=14
I rooted my phone and had to restore with kies three times before i got my wifi working. This is only if I switched to SuperSU, if you stay with kingroot, you wont have the wifi issue.

Help help help!
I did this and now my wifi won't turn on!! AT ALL

so the root metod its safe??? now there is another metod done from between Android using terminal emulator to switch from kingroot to chains fire super su! you have to be fully rooted to be able to work on terminal emulator.
but the root metod for sm g530az its safe?

flashing the stock kernel, do you click boot image or recovery image?

OK, I got the wifi to turn back on by using the link above again.
I still cant get the wifi tether app to work, tho.
any suggestions?

well..happy to report that root on criket grand prime sm-g530az its a big...SUCCESS!!!
Im rooted on lollipop 5.1.1.
i do have cwm recovery but i need to flash it and see how it goes.for those with the Wi-Fi problem flash that boot image again.i have two one didn't work so i flash that second and Wi-Fi was working again.
Samsung bootlogo reports as "custom" so guaranty its gone
but I don't care abt that,im rooted thnx guys for sharing all that informacion!

I got the root to work with kingroot, but didn't do the 'optional' SU part, but now I want to.
Can anyone tell me what the step is with that zip file? do I download it directly to the phone? use Flashify? if I'm using flashify, do I flash it as a "boot image", a "recovery image" or a "zip file" ?
LOL talk to me like I'm five, please! I'm a noob at this. I'm smart at some things but this is a little overwhelming. LOL I'm a critical care nurse. I can fix a PERSON, but phones are a little more complicated :laugh:

Wait you have cwm compiled for our sm-g530az? That would be useful

Okay thanks a ton for the info, finally got my wifi back after flashing the correct boot.img, not sure where it was on the original forum never saw it but luckily others that had same issue posted it.

Going to try to blow the dust off my builduntu box and see if I cant get us a recovery going for the cricket version, I usually like twrp but now that cwm has touch as well could go that route....is their a custom recovery built for the other variants at all yet....if so then forking those repos would be a good starting point, should only take minor edits to get it working proper for us.

I already built twrp for this phone, but as you found out, the damn security checks prevent the use of it. This is my device tree, can't remember if I pushed my last commits and I dont have what I had, due to a hdd failure.

So can you get a custom recovery working for this device? I have tried many ways but they all ended with my flashing stock img. twrp or cwm would be fine by me. Or another alternative is to find out how to disable the security check. Anyway please find a way to get custom recovery for 5.1.1 SM-G530AZ. Thanks

Okay I think we should put our heads together to try and kick this lockdown to the curb, things I have tried so far...I found that on some other variants they have the option within their settings/developer settings menu to enable oem unlock which is what we are needing to be able to flash custom recovery, I have replaced my settings.jar and settings.odex with theirs with no luck the option is still not showing up for me, but I think it may be the right direction into getting that to show up, the question i am now posing is this. Are the checks in place simply reading carrier info to allow/disallow this option? If so would we possibly be able to change the build.prop or other settings with our newly found root access to trick the device into giving this option? If that is the case then we need to get as much info from the stock devices that have that option as possible and maybe try swapping certain files out with theirs to get the option back and/or editing certain files on our own device to get it to show up. It only takes one g530AZ with unlocked bootloader to share the boot.img i would think. I had thought about flashing another boot.img or aboot.img from another variant but I am pretty concerned about brickage although I think it could be recoverable as long as one can get back into download mode. Has anyone zeroed out the download partition to see if a fastboot is hidden behind it?

No Os Installed!

I left my phone charging and came back to get it. It was stuck on the google logo, I am able to boot into recovery but it says No Installed.
Is their anything else I can do other than flash it again.
I was thinking maybe the wrong partititon was checked, but everything looks fine.

Assuming that the ROM is still there, you can dirty flash the ROM zip over it, and see if it works. There's no harm in trying that.
But "No OS Installed" simply means that your /system or /boot parition are not detected (means, they are empty). Now of course, the last resort is to flash the ROM all over again.

You need to provide more information. Are you on the stock ROM or a custom ROM? Stock recovery or TWRP? Had you made any changes to the device recently?

Someone please help. I just rooted my 6P. Did a little bit of doing. Phone would never boot just the round circles. So went into TWRP and tried to wipe to start fresh, not it says no OS installed. I have no ROMS's on the phone. No boot images. Been a while since I've done this. Really need help on this one. Thanks.

Download the dp3 , boot into bootloader, connect to PC run installer script after you unzip the factory image " flash all" sit back and wait for phone to reboot.
---------- Post added at 10:30 PM ---------- Previous post was at 10:29 PM ----------
It's that simple.

Hey thanks a lot. Couple things, and I apologize in advance for not knowing this already.
1) what's dp3
2) how do I run installer script?
I know I shift right click and open a cmd window within fastest - where I'll unzip the file - and I know how to get the phone into Bootloader.
Again, sorry for asking for simple explanations.

Download any ROM ( like pure Nexus) and gapps
You can use USB otg to flash the ROM using twrp or transfer the ROM file from your PC to your phone in twrp (it supports mtp)
Simply flash ROM and gapps and viola

Download the required ROM and gapps, connect your phone to pc , type in google, Mini adb and fastboot, a page on XDA itself will come, download it, its small and install.
Then copy the ROM and gapps package to the location of the installation of the application.
Now open your recovery and tap on adb sideload, and swipe(twrp)
Go to your PC, open adb application a cmd will appear, type adb devices, it will start a daemon then will give you your device number, a number should appear. Then type
Adb sideload """"name of your ROM package""".zip
It will start installing, wait for few minutes.
Do the same for gapps
Adb sideload " name of gapps package ".zip
Then reboot
Its fixed

Why are you telling him to install the Developer Preview? He wouldn't want that unless he's actually asking for it, which he isn't.

Developer preview 3 is a Android N preview and it is very fluid, battery life is good on stock and reason I recommend this because it is simple to do, gives you good options within the ROM and is good overall but that's just my opinion.

Lol. Maybe you missed the title under my name.
The dev preview isn't what he asked for, it isn't an easy solution, it isn't easy to come back from if he doesn't like it, it isn't even remotely what he needs. What he's looking for is a simple way to get his phone booted up and working again (a very simple request), and what you're suggesting is he install a beta OS (a complicated "solution").
If you really have a problem with a moderator requesting that a member posts in one place at a time (as per our rules), then I'm gobsmacked. If you'd care to look at the advice I gave him in the guide thread where he also posted you'd notice that I gave two solutions that:
A) Actually address the simplicity of his problem.
B) Give two simple, easy to execute, solutions that are the most common solutions you'll ever see anyone give a member in his situation. Solutions that don't involve having to install a developer preview that he never asked for.
I get that you're trying to help him, but the "solution" you provided him isn't right for his situation at all. There was no need to become defensive and aggressive when this was pointed out.

AT&T Samsung Galaxy S7 G930A Root Install Instructions?

If anybody can put up a step-by-step guide, or a video that shows how to properly install it all, I'm sure myself, and much of the community would appreciate it.
Recently, my laptop that I had ADB, and every tool imaginable for Androids, and specifically the Galaxy Series, took a huge dump on me and I lost it all. I installed it so long ago, that embarrassingly I've forgotten how I did it all. If someone could post how they rooted their GS7 (non-edge variant), I would be very appreciative. And I'm sure much of the community would be too. I'm embarrassed to even have to ask as someone who used to formerly develop mods on phones. But it is what it is. It's been so long since I've set it all up, and I've had to do so much since that time that I've simply forgotten how I did it/how to do it. Any help would be GREATLY appreciated. Thank you ahead of time...
I've tried following the instructions in the sticky above. I ran the 930X ROOT.TAR in the special version of ODIN. And every ran OK. It said "Success" and then rebooted. All seemed well, then it froze on the AT&T Boot Logo. What can I do from here? I know from history that this is one of the points that people panic and claimed "brick" (though I've never seen a real brick from rooting). Any help would be greatly appreciated

There's a great guide in the Verizon forum. Root was universal based on FW. Just make sure you flash the correct 930 or 935 with the modded odin. I recommend you follow the steps to "unroot" for the sake of doing an extremely in depth factory reset. Also make sure you get chain fires latest supersu built for the s7qc.

yup. Great instructions. All set rooted now. Now time to play with xposed and V4A and the like. Yay

OK. Followed the instructions on the Verizon page and used the PrinceComsy version. Stuck at the AT&T logo. How did you go past this step? Should I have used the standard version? thanks

(keep in mind this is only my personal experience...)
but the PrinceComsy version of ODIN was the only one to work for me. How far exactly have you gotten in the process before you got stuck at the logo? You do have ADB installed correctly installed on your PC and turned on on your phone right? and cd-ed the specific "super" folder for the SU adb install, right? FYI: It's not a simple root process, like 1-click roots on previous devices. This is more similar to the in-depth root methods like on the N1 and D1 before super nice devs went out of their way to make it simple. So if you're not familiar with ADB shell and the likes, it'll be difficult for you. But, no matter how high and mighty or condescending people act, we've all had to start somewhere. I'll help you get through the process as much as I can

Thanks for your reply. BTW I am fairly experienced in this stuff. This is what I did to get it to work. ADB and drivers all work fine.
Flashed the boot image using the PrinceComsy version. Got stuck at AT&T logo
Attempted to flash with the other version of Odin. When I open Odin, a window would pop-up with some ini issue and Odin would close immediately.
So I moved the ini file from PrinceComsy version to the other version. At this point, Odin would open and detect the phone at the correct COM port
Tried flashing it with this Odin but I got a SHA256 error
SO..
I went back to stock (which deletes all data, no big deal - everything was backed up)
Boot was successful
Re-flashed with the boot image and viola!

Thanks for the ping. I think so. One thing I ran into which I don't know if its related to rooting. When I am in a phone conversation, audio on the other end goes in and out after a few minutes into the call. This happens with bluetooth or not. Still figuring out this issue.
