Yes, yet another JH7 thread. But this one might help you gain your sanity back.
JH7 will (but not limited to):
1. Remove PC Internet option for tethering: When you go to Settings, Applications, USB Settings, you will not find the PC Internet option. If you currently have "Ask on connection" selected and you connect your phone to your computer, you will not see "PC Internet" as one of the options. This means, you will not be able to tether your phone to your computer (using the built-in tether feature).
2. Give you a better GPS lock: Some people have commented on how fast their GPS locked. It may have even improved the GPS accuracy. After installing JH7, mine locked in 45sec on the first try. After a reboot, it locked in about 15sec. Also, you cannot access the GPS Lab Test by dialing the *#*#.
3. Install Quickoffice: While you can download and install this yourself from the Market, JH7 installs it for you.
4. Update YouTube widget: You will see rotating thumbnails of the "Most Viewed" videos on the YouTube Widget.
5. Adjust the display's lowest brightness settings to even lower (is it just me or are my eyes tired from reading through so many JH7 threads?): I have my display to not adjust automatically. This allows me to slide my finger across the top status bar to manually adjust my settings. I always leave it to low (under normal room lighting conditions) and I can still see the display just fine. After JH7, I'm having trouble seeing the display. I just manually adjust it to one tick brighter. Problem solved.
6. Removes unlock code: http://forum.xda-developers.com/showthread.php?t=789888

Having said all that (based on my current experience with JH7) you should think twice before updating. I (kind of) did. Keep reading.
This is what I did while still on JF6.
A. Rooted my phone using One-click Root.
B. Installed Titanium Backup.
C. Installed ROM Manager.
D. Deleted AT&T bloatware.
E. Created a backup of my current (now semi-stock) ROM.
then, I...
F. Updated JF6 to JH7.
G. Played with JH7 and noticed 1-5 above.
H. Restored my phone using ROM Manager using the backup I've created (see E.)
Even though my Baseband still says JH7 after the Restore...
a. I got PC Internet (tethering) back!
b. YouTube widget is back to the old version
c. GPS takes longer to lock, >1min
d. I can access the GPS Lab Test by doing the #*#*...
e. Quickoffice is gone (of course. I never had it in when I did E.)
f. Brightness setting still behaves like JH7
Lesson: Create a backup before updating if you want to retain some settings and features!
EDIT: One last note...it may brick your phone, according to some people.
AT&T wants to remove phone tethering? Big surprise there.

If you can get to the factory reset in the settings menu that would the first thing to do. And then check for an update. Make sure you set the wifi to not turn off and I would keep the screen from shutting off while downloading the update. Check in settings "about Device". If your not 3389 or higher then you need to update
I had this problem back in November when I first got my tab. Even though nothing seemed to work right, I was able to connect it to my desktop and push across clockworkmod v .08 and a custom rom. So, I never used the original rom more than 10 minutes.
If you can't get it connected while booted in original rom, then Bekit's NVFLash full restore procedure works really well. Just follow the steps carefully and it's a quick and painless factory reset to a known working rom.
These things are virtually unbrickable (is that a word?).

badfrog is correct. If you factory reset the device it should be fine from there - then you set up your wifi and get the update.
Go into your app drawer and choose Settings. I don't remember if you can do it from the menu button as I'm on a different launcher.
Inside Settings go to Security and select Factory Data Reset. Do this, the unit will reboot and come back up at which point you'll be asked to set it up. It may take some time. Set your Date and Time correctly and set up your Wifi and such.
Once that's done you'll likely get a prompt to update very soon after Wifi connects. DO NOT DO IT, yet.
Within Settings, go into Display and set the Display Timeout to Never.
This ensures that the tablet doesn't sleep or turn off your wifi while it's downloading the update. It's not likely to happen but if your connection is on the slow side and the timeout is set too low, it can mess things up.
Once you've done that, proceed to let the tablet update itself. Again, it may take a bit of time.
Once it's done, make sure you take not of what you have. You'll find this information under Settings in the About section. The last version I got was 3389 - but something newer MAY be there for you. If you get anything less than 3389 then you will have to wait until you get another notification for an update. I don't remember how they work - but I THINK you should get the newest one there.
Once you've confirmed you're on the most current build, It may not be absolutely necessary to do it, but I would factory reset again just to clear the 'gunk' of the older TnT out in case there is actually any.
When I got mine and powered it on the 1st time, I got a bunch of FCs. I powered off and then on, and no more FCs, and it was fine after that. I think I posted asking about that, and someone (roebeet, I think) said it was a known problem. I don't remember the TNT version, but it was the one before 3389, or one before the one before 3389.
Jim
It is a known problem, especially with the older firmware. Sometimes the FC's are so bad that you can't even get into the settings to do a data wipe.
I've actually called CS about this, as an example of why they need an offline updater of some kind to get around issues like these. Suggestion: if you don't want to install clockworkmod, at least try to update the firmware to the latest and greatest, via one of the newer stock ROMs we're retrieved:
http://forum.xda-developers.com/showthread.php?t=842000
That might get you enough access to get into the Settings menu and do the factory restore.
Congratulations on your new Purchase. The Tmobile LG G2x is a beast. Like all new devices, you may experience new service options and features you may not be familiar with and may cause some trouble down the line if not set up properly. We also want to make sure you are away of all of the known issues and some faulty units so you are aware and can check while still within a reasonable exchange window.
1. Get Connected! By default you won't be able to access the SD card via USB because it is defaulted to mount the Internal Storage, which requires the LG Driver.
To get around this, or if you only want/need access to the SDCard go to [Settings>SDCard and Phone Storage] and check "Mass Storage Only". This option doesn't require special drivers and will operate like most other phones.
The folder hierarchy is as follows:
Code:
Internal Storage: /sdcard
External Storage: /sdcard/_ExternalSD
1A. How to Delete your LG Drivers to use MASS STORAGE and to advert the Blue Screen of Death:
Obviously on Windows: Go to Start>Control Panel>Programs and Features find "LG Android Drivers" in the list and uninstall.
2. The first big problem on a few handsets is a backlight bleeding. You can test this by viewing a black screen in a dark room. You should have a solid color throughout. If you have really bad bright corners, you may be a victim of the bleed. While not quite a set back, it may be noticeable while watching movies or playing games in the future. If this is something that bothers you, I advise to swap it out for another unit.
3. There seems to be lots of "weird" issues ranging from grayed out options or behaviors such as lockscreen sounds not working. Most are assumed from faulty Titanium Backup restores or by simply skipping the initial setup. It is recommended that if you have done any of these things, to do hard format and set it up manually, recreating backups and program restores.
4. Like other later handsets by Tmobile, you may see WiFi Calling in the App Drawer. It works fantastic and is great for desperate times when you don't have available cell service. What you need to know is that it is ENABLED by default. The problem is WiFi Calling is designed to disable your actual Cell radio to save battery. What this means is that if you enable your Wireless and bounce around stores or in/out of WiFi service, you may be missing calls and messages while you are offline.
I recommend turning WiFi Calling OFF and enabling it only when needed.
5. WiFi is set to go into sleep mode after X amount of inactive minutes to conserve battery also. While a great feature, if used in conjunction with WiFi Calling, you may find your WiFi goes to sleep and you can start missing calls and messages also. To change this to go [Settings>Wireless & networks>WiFi Settings] + Hit Menu>Advanced]:
Change WiFi Sleep Policy to: Never
6. LG, like most other manufactures, develop their own drivers which may or may not be compatible with everything. With the LG G2x we are finding that some Bluetooth profiles may not play nice with your gadgets. Please check these as soon as possible. Some items may be Car Stereos, Specific programs using certain bluetooth profiles, and handheld gadgets such as gamepads or wireless speakers. Most will work but a few reports suggest the drivers may be off. Again, for your satisfaction, please check as soon as possible.
7. Root:
-Enable "USB debugging" [Settings>Applications>Development] and connect your phone to your computer via USB.
-Install ADB Drivers LG Driver.
-Run SuperOneClick: SuperOneClick
-Choose the option "Root".
8. Get rid of Bloatware using Root and Root Explorer (from market):
Here are a list of apps you can delete from the (/system/app/) folder:
Code:
AppPack
TeleNav
NOVA Demo
NFSShift
LMIRescue (LogMeIn.Rescue)
LMIRescueSecurity
EAPK = EA Mobile
MyAccount.apk = "My Account" and "My Device"
ZinioReader
ZinioSettingsProvider
9. There was also a report of using a HTC EVO Micro HDMI cable that shorted out the phone. This was a big deal over in the EVO thread. The problem is the way the cable was made and can short out with the external metal casing. If you purchased one of these I would proceed with caution.
10. If you want to make a solid backup of your current configuration or FLASH ROMS then you'll need ClockworkMod Recovery. There are two current methods to doing this. Both work but this is the best option because you can boot into Recovery via Volume Down + Power in case something gets screwed up and you get thrown into a Bootloop. The other method is by simply downloading Rom Manager via the Market and installing it that way. Although the second method does not allow booting directly into the Recovery console. So just do yourself a favor and download the latest ClockWorkMod NvFlash App for Windows
Feel free to add to this or perhaps add this information to the Wiki. Please give me a THANKS if this information was useful.
thanks, getting phone wendesday and will do all this. shouldn't the charging battery and discharge thing and factory reset be on there also from what i read.
Very helpful! Thanks a lot

Can you unroot with that method of rooting? I'm afraid to root because I'm not tech and android savvy and have no idea what I am doing. Plus, I have all macintosh computers, will downloading that stuff be a problem?
This is excellent. I figured most of this stuff out on my own, but for anyone still trying to figure out his or her device, you've pretty much taken care of everything. Needs to be stickyed.

Well Root just gives you admin access, which means you can do anything. Some programs require root to really get down to business, such as some of the better backup programs so they can backup a lot of the stock apps and personal settings.
Once you root there is no reason to unroot. It doesn't change anything, except permissions.
And not to worry, any application that requires root will pop up asking for access which you can accept or deny.
The main reason for Root is to use Rom Manager, which installs a custom recovery so you can flash custom roms and other files that can alter the look or functionality of certain parts of the OS. If you have no intent on altering the existing OS, you don't need root access.
Without Root, you will still be able to upgrade to new official upgrades and fixes.

Good question. On my Nexus One you hold the Track Ball, Vol Down, and Power. Lacking a trackball I guess there is not a way. Would be nice since there isn't a "Reboot" in the power menu on stock android.

Okay, well I plan on changing the look of the phone most likely, not I think mostly what I want to use it for is to delete bloatware like the t-mobile apps that may be using up a lot of my battery. Then is it worth rooting?
And also once you root it, is it complicated to alter the look and functionality?
My G2X and my Nissan Altima 08 doesn't go well over Bluetooth. No sound. I thought that was fixed in Froyo
good one !
AppPack- is it applicationsProvider.apk?

there's a reboot widget in the market. works great.
Can we delete/freeze SmartShare? I guess it only works with LG TVs.
Having a crazy day. Got the new ChevronWP7 unlock last night. Did the internet sharing interop combo. Now get error trying to reload xap files. Trying to put on accentchanger file.
Error - failed to connect to the device. Ensure that the device is connected..
The xap app is not supported
You have to deploy supported xap only
Ex:
Screen cupturer
Nokia maps
Battery status
Tango, but it is now in marketplace
Some other apps like Native keyboard are not working.
Good luck.

@verynuclear: Not sure what you think you're trying to say, but it's totally possible to use high-privilege apps like Advanced Config (which does custom accent colors, among other things). You just need Interop Unlock, which is easy on LG, possible (via an app) on Samsung, and difficult but not impossible on HTC (I have it on my HD7).
The problem is that after using the Interop-unlock app on his or her Samsung phone, the OP seems to be having trouble with the XAP deployment tools. @jgibo, I suggest you read and then post in the relevant threads for those apps, rather than starting a new thread.
The main reason for asking question is if the deployment tool stopped working for anyone else. After I got Chevron on there I was able to install screen capture, accent changer. Screen capture worked. So I removed accent changer and followed instructions for interop unlock install. Then saw the thread for internet sharing and interop in one. Installed that to phone. Got internet sharing Then tried a few different xap files and couldn't install any. So did that xap mess something up? Guess I will look elsewhere for answers.
This is all they have on MSDN site.
--------------------------------------------------------------------------------
This can be caused by several reasons, including if the device is off. If the device is already connected, sometimes disconnecting and then reconnecting the device may fix the problem. Rebooting the device may also fix this problem
You do have internet sharing OFF right? You can not deploy XAP's with ICS on. I don't mean to be rude but it really does pay to read the whole post when someone gives instructions on how to do something before saying it messed up your whatever.
voluptuary said:
As long as your device is unlocked in some way (Developer/Chevron/Other) you can get internet sharing on your Samsung phone.
1.) First install the WP Dev Tools and unlock your Samsung phone.
2.) Use the Application Deployment tool to send THIS to your phone. You do not need to run it and you can delete it after it has been deployed.
3.) Install the Diagnosis app by typing ##634#
4.) After the Diagnosis app starts type *#9908# and select 'System Tweaks' press 'Save' then 'Close' and RESTART your phone.
5.) Your phone now has internet sharing and as a bonus is interop unlocked!
PS: You need to have a recent firmware on your phone or your diagnosis app and drivers will not be new enough to work.
EDIT: I built the file depoyer app using the tools provided by Heathcliff74 so many thanks to him! Also ADC is built in as well so no need to worry about that and I also upped the max number of connections from 3 to 5 devices.
NOTE: If you have internet sharing turned on (active hotspot) you will not be able to deploy XAP's untill it is turned off. Also, as with any xap, you need to have your screen unlocked to deploy.

Of course if you have ICS off then I'm sorry for this little rant and all I can suggest is restarting your phone and PC and trying again.
ICS is and was off. Found other posts with same message. Currently reinstalling dev tools. I do IT support for a living and hate havinng to do troubleshooting on my own stuff From past experience with computers it is either a coincidence or cause when a new problem occurs. Hence the questions asked. I do remember seeing an odd usb error in system try when I was doing step 4. Did a troubleshoot on my Focus connection but that didn't help. Also tried all usb connections. If the reinstall doesn't work will have to get my htpc out and try on it.
Reinstall didn't work. Since it stopped after running system tweaks I am trying again. Wish the instructions had a note on how long after hitting the save button before it was done. Has the Loading GPRS Profile for System Tweaks on screen. I think I may have hit the close button yesterday while is was still showing Loading. Right now I am not touching phone till I see it go away. Unless you are supposed to hit close right after hitting save.
The settings are applied almost instantly, as soon as it says loaded after you hit save then you can hit close and restart. Another user stated they had to turn ICS on then off again before he could deploy XAPs. Another question, you haven't turned on wired tethering have you? I ask because if you don't set your phone back to Zune sync you also will get the error you are getting.
EDIT: Main question, does Zune see your phone when you plug it in at all? Can you sync media? Cause if you can't you have another issue that is beyond anything my XAP could have done.
That kind of worked. Turned on ICS then back off. Got Advanced Config to install. Now get UnauthorizedAcessException. Click ok and app closes. Go from one issue to another.
I picked up a new GoGear last Saturday.
This is my first Android based device, and I do not have a cell phone. Thus in that sense I am a noob.
I was initially able to connect to my home network; however, after figuring out how to root the device and adding a sound file to the the media/alarms folder I was not longer able to use songbird. I fixed that, and now I am no longer able to connect to my home wifi. I have tried a reset, a complete wipe (using the built in privacy erase function etc.) and also tried using the repair function on Songbird - it was fail during the install of the firmware.
I have eliminated issues with home wifi security by setting the network to broadcast, and removed security functionality. Despite that the network search finds the network, displays a message that it is obtaining an IP address, and then after a few minutes it stops, and reports disconnected. The process restarts, and then eventually the message of disabled comes up.
This morning, I tried using the idea of installing a new ROM hoping that would solve the issue: (From this thread).
http://forum.xda-developers.com/showthread.php?t=1396085
Still the same issue, everything seems to work, except for the wifi not connecting.
Any help, ideas, suggestions, etc. would be appreciated.
Thank you.
Update
Problem Solved,
Not quite sure how, but here is what I did.
1) I re-rooted the GoGear again
2) I removed the sound files that I put in the alarm folder.
3) I downloaded FXR Wifi Fix and rescue apk to the sd card:
I cannot post the link but it is from appbrain.
4) I installed this app, and ran it.
5) Reboot
6) It worked- alas, I do not know what the cause was.
If this helps anyone else, great.
Thank you to all who viewed my first post!
I just bought a U11+ as an upgrade to my U11 and am configuring it, which is taking longer than I expected because neither of the two backups I did (htc's and Backup Your Mobile) installed most of the apps (or their data). Also, I've had two System updates in the last two days.
I got my custom background, the Keep Notes app (plus its data) and Facebook; that's pretty much it.
What did I overlook?
Oh, yeah... I cannot find a setting to keep the display on when powered. Anyone know how to do that?
If you did a jump to a new OS version or device that may be why.
If you did any major firmware updates on the new device, it's factory reset time.
Otherwise clear the system cache.
Manually loading them may be your only option.

That occurred to me when I (finally) checked the OS version and saw that it was 8.
I've been getting update notices for the last two days and the most recent one (the third) was the Android 9 OS (update # 2.19.401.2). Where can I check on official updates so I can get an idea when this will stop (because manually looking for updates this morning got me nothing, then I saw the update prompt a couple hours later).
Updated to 9, rebooted and verified that Google Drive is connected, but I'm still not getting Backup & Restore to work. Will have to experiment with the others.

I learned long ago that if your OS is fast, stable and fulfilling its mission, let it be.
I've been on Pie for 2 years, my last reload was 1.5 years ago, still fast and stable with minimum maintenance. What's not to like?
Unless you start screwing with the firmware and bring in new issues that need fixed.
Security generally isn't an issue unless you do something stupid.
There's no saving dumb bunnies... be careful what you load and download.

I did a Factory Reset (but it stayed Android 9). I did this because I had 'restored' a lot of files from Backup Your Mobile's (aka BYM) work on my U11.
Two things are bothering me:
1) The HTC Transfer Tool is not working this time (it transfers the PIN Code, but never gets to CONFIRM. After repeated attempts following reboots, etc., I have noticed that the PIN Code sometimes flickers off and back on again; what's up with that?).
2) BYM transferred my SMS and MMS to my U11+, but clicking on a text message that includes an MMS just makes the message thread avatar flicker and stay on the message thread listing (not even a flicker of the thread is displayed).
You mean screen lock codes?
First I don't password lock devices. You're the most likely one to end up getting locked out.
If you do use one I wouldn't attempt to back it up and transfer it. If it gets corrupted what follows won't be fun.
Pie's a good OS.
Clearing the system cache never hurts to try when experiencing glitches.

No, I did not mean screen lock codes. The HTC Transfer utility worked the first time I tried it before the Factory Reset, but it's not working now. The PIN Code is displayed on the source phone, but it doesn't activate the confirmation button to do the transfer.
I have since learned that many of the apps that were copied over via Google Play's utility also transferred the data, but not all the apps were transferred.
More research to be done, it seems.

My bad... I use Google search a lot and it doesn't need to be that specific model or OS version most times. Many of the issues are long standing. I even use solutions for other manufacturers models. Whatever comes in handy.
And/or just play with it until I work it out.
I haven't used that app. If you upgraded the firmware or are transferring data from another device these kind apps can screw up especially with app settings.
If you're doing a factory reset because of an issue or a crash they can inadvertently reload the root cause of the issue.
It's nice to save the homescreen, theme, icon setting on a reload using these though. Most apps I hand reload/configure or use the app's backup setting file like with Poweramp or DIGI Clock which are very intensive to set from scratch.
Critical data I save in a master backup folder(s) as files. Be ready to reload at any time as most crashes while rare give little or no warning. Redundantly backup critical data to at least 2 hdds that are physically and electronically isolated from each other and the PC.
Most times a factory reset is to give the device a clean slate. Looking over app settings while setting them up helps to spot things you may have previously missed. It helps a lot to be familiar with the nuts and bolts at the user interface level. Many times when troubleshooting this is where the answers lurk.
I consider my first load or two on a new phone trail runs. After which it's pretty well sorted out for a clean load. I do the same on PCs. Android's are very forgiving but poorly written apps or the user can still skew hidden user settings that are hard to find/access on a stock device. A stable, fast load is a pleasure to use and will run well for a long time with only simple maintenance on a stock Android.
