Just odin back to stock
[Vibrant Q&A, Help & Troubleshooting] SimeonAS89:
So go back to stock and follow the same steps as before?
[Vibrant Q&A, Help & Troubleshooting] crazy25000:
Odin back, then follow instructions carefully when flashing gingerbread roms because they are a little more tricky to flash.

In the blitzkrieg rom install instructions, he offered two ways to flash it. Which method did you use?
[Vibrant Q&A, Help & Troubleshooting] SimeonAS89:
I used the bootloader method while on project v and the 1.2ghz kernel for gingerbread. Although I could not get heimdall to work right so I used odin instead and everything worked fine.
[T-Mobile LG G2x] GManLynx:
Hey fellow G2x's. I rooted my phone today and attempted to install CM7 nightly #56. FIrst of all...

I tried just downloading the rom via rom manaer, clicked wipe data and wipe cache. When I did it tried to install and asid "Could not open cm7nightlyetc..." And then it proceeded to reboot itself as if it was a new phone.

I then tried to do it via recovery. First whenever I click install from zip card then choose zip from sdcard, the only file I can see is LOST.DIR/ even though I deliberately moved the rom into the sdcard/. I was met with the same problem.

During both the encounters. a triangle with an ! appears, with a little android dude next to it. WHat does this mean? What do I need to do to fix this?
[T-Mobile LG G2x] techboydino:
First rule of G2X/Tegra2 club... don't use Rom Manager. Use CWR for all your flashing needs. *Install CWR via NVFlash only.
[T-Mobile LG G2x] GManLynx:
Alright, I'm sorry but I came the G2.... And I was wondering what NVFlash is? I'm gonna google it, but it will be nice if you answer it too.
[T-Mobile LG G2x] darbear5610:
Setting up NVFlash

Here's the guide to setting up NVFlash. It's a moderately challenging process, but it's seamless after getting it put on your G2x. This is the only way to get CWM without issues. http://xdaforums.com/showthread.php?t=1054492

Oh, and remember to go into C: on your computer and make the folder "G2x". This is where you put the files from NVFlash.
[T-Mobile LG G2x] sarni84:
yup and when u get ready for commands u can copy and paste them
[T-Mobile LG G2x] gaww:
First - the above is the truth - learned the hard way by many.

From the "triangle" comment, I would have thought you were not able to get into recovery anymore, but you said you had tried flashing in recovery - are you still able to get into recovery? Also, when you said you moved the file to the SD - internal or external?

You could re-download the ROM on you computer and/or move the one you downloaded when in USB connect mode if you can connect through USB. and then try flashing it again.

Otherwise - did you do an nandroid back-up first (add that to the G2X Club rules). If so, and you can get into recovery, you can restore it through recovery. If not, you are truly back to square one (except for rooted).

At some point, you need to NVflash a real recovery. The one-click method in the Dev section is the easier way to go. If you can't get into recovery (you only see the triangle and it only does a factory reset), then you HAVE to start there.
[T-Mobile LG G2x] GManLynx:
Yeah I am still able to get to recovery mode. And external sdcard.

I think i'm just gonna go staright to the NVFlash way. I have a history class today so I have a hour and a half to burn.

And thanks guys for all the inputs.

I'm loving my G2x so far. So fast and sleek :)
[T-Mobile LG G2x] player911:
All you need to do is NVFlash once, just so you can get into recovery on a bootloop (Power+VolDown)

After you install NVFlash once, you can use RomManager all you want (I do).

Rom Manager will install a temp recovery initially, but it won't affect your permanent NVFlash recovery. So just do both. Rom Manager will work perfectly fine without doing a NVFlash, but an NVFlash just enables the option to get into recovery on a cold boot.

Every day, I launch Rom Manager and it will find the latest Nightly and download it plus Google Apps, prompts for Full Wipe, Backup, or Cache options, then it will reboot, flash the items, and reboot back into Android.

So, again, NVFlash just enables Power+VolDown to get into recovery but Rom Manager works great without it. You SHOULD do BOTH initially and just get it out of the way.
[T-Mobile LG G2x] GManLynx:
Alright thanks. I just installed via NVFlash and now I will try again to install CM7
[T-Mobile LG G2x] gaww:
Agree with all the above (I have and use both), except for making nandroids, which was not mentioned above. The only ones where I have had a check-sum issue with trying to restore are nandroids I did with ROM Manager. I would stick with doing them straight from recovery.

Others have had issues with flashing nightlies also, but I have not noticed that as I always head straight to recovery to flash.

Question - I had flashed real recoveries with ROM manager on MT4G - why the "false" recovery issue on G2X?
[T-Mobile LG G2x] Mikeglongo:
So player, once I have NVFLASH and CWM, I can download ROM manager to backup/restore/flash any ROM from the list without worrying about anything?
[T-Mobile LG G2x] GManLynx:
Hey, I installed the 4.0.0.3 and I still have the same problem. I can't see any roms I put on the SD card, and when I try to install it by naming it update.zip it gives me the same error. Any ideas?

OKay so here is what happens

Installing: /sdcard/update.zip

Finding update package...

Opening update package...

E:Can't open /sdcard/update.zip

(No such file or directoy)

Installation aborted

THere is definately a file there. I just named it that cause it wont shop up when i choose zip from sd card.
[T-Mobile LG G2x] Mikeglongo:
I would redownload the zip file over the computer, happened to me before with a different rom, make sure it doesnt unzip. and then drag it to your SD card.
[T-Mobile LG G2x] GManLynx:
Okay I am perfomring that now, will edit with results.

My goodness... I think you fixed it for me. I feel like an idoit. I've been saving it to hte internal Sdcard i didn't even know that was possible.

Damnit... same problem.

Yay I got it. Thanks so much guys for all the help.
[T-Mobile LG G2x] gaww:
The ROMs were probably going to the internal SD by default. Just move them with a file manager to the external SD (unless you set up recovery to use the internal SD).

Also, do not rename them update zip - leave the names as-is so you will know what your are dealing with if you have multiple ROMs .

Then you flash it as a zip file on SD card - not as "update.zip" - that would be for the OTA update - if we ever actually see one for the G2X!
[T-Mobile LG G2x] Mikeglongo:
Good job Gman:)
[T-Mobile LG G2x] player911:
Different roms put the external SD card in different places.

By default Rom Manager is set to read/write to /sdcard/... not /sdcard/external_SD that is the norm with the stock(based) roms.

Once you have CM7 on there and everything setup under standard conditions, Rom Manager will work as it should.
[G2 and Desire Z Q&A, Help & Troubleshooting] ajhavery:
I have searched through the roms availbale for download via the ROM manager, but I couldn't find the Virtuous Unity ROM anywhere.

Everytime when an update arrives, I have to download the ROM through my laptop and transfer it to my phone, then only I could install the ROM.

Can someone tell me how to fix this problem?
[G2 and Desire Z Q&A, Help & Troubleshooting] Nipqer:
The devs have not put it on rom manager yet, there's nothing you can do.

[Fascinate Q&A, Help & Troubleshooting] poppajules:
Two friends at work have samsung galaxy s's.. one has a fascinate and the other has i9000. i would like to know the differences between the two and the differences in the rooting process for each. from what ive gathered in the short time of research, they seem very similar.

have there been any recent OTA's blocking root privileges? (friend had evo, didnt listen to me, downloaded OTA, and currently cant root with 2.3 OS.)

What are the most common errors or 'bricking' to avoid? i would like to NOT have to build a jumper lead if i dont have to, but i do know anything is possible. (short story, rooted friend's droid x this morning, and it boot-looped on the ROM i run on my x, following typical procedures, so had to start from the beginning of the process before i had successful root)

I wont say that i am a noob to root. ive lurked xda, CM, droidxforums, etc., etc., rooted my eris, OG droid, three droid x's, sprint hero, incredible, and looking now to continue to expand the horizons of phones with root, as well as people at work i can 'nerd-talk' with about themes and root-only apps.

With all that said, Odin and some of the processes ive skimmed for this phone are definitely new, so i kinda need an end-item list of the process.

Thanks to all devs, experienced folks, and mods for the help in advance.

no one has complained yet that I know of offhand. I used it for a week or so before deciding the benefits of GB weren't good enough for the shortcomings due to the leak the roms are built off of so far.
[Thunderbolt Q&A, Help & Troubleshooting] chrisjm00:
I ran gb for a week or so and went back to froyo. The leaked radios have horrible lte speeds. Sitting the phone in the same spot I would average 5-7 megs down on gb as opposed to 13-14 on froyo. I don't know if this is verizons way to cap speeds to coincide with their tiered data or what, but either way it was much slower.

I am having problems with openvpn and I would really appreciate any help that I can get. I was not able to make openvpn work on Eagle Blood rom. Here are the steps I used. I installed binary file at the system/xbin using the openvpn installer from the market. I then created a folder at the root of sdcard and named it openvpn. I placed in the folder the configuration files. I then downloaded and installed openvpn settings from the market and tried to connect to openvpn. It would connect to the server (a small key would appear on the top of the screen and says connected) but data would not be tunneled through the vpn. My real IP address would still show while connected to vpn.

BTW, I flashed cyanogenmod 7 nighties #53 and it worked. I use simple mobile and data does not work with cyanogen since the APN needs to manually configured and with all the APN issues going on with cyanogen at this time, I would prefer to use another rom that would support openvpn.

Thanks in advance and I apologize in advance if I posted this at a wrong place. I am new to XDA forums.

[Galaxy S II General] dhruvmalik:
Thanks for the in-depth analysis.

I figured it as much that it had to be Active Widgets that cause a higher drain than normal. I dont have any widgets active and dont have any drain, but I can see them running as a service.

I always wondered that if they were removed from the service, will the battery life improve or not make any difference, since the widget isnt really running, only the service. Force Quiting the Widget Service only has them come back shortly after.
[Galaxy S II General] [germany]merlot:
Ok I jump in. I've the same issues. Now I disabled my lockscreen (widget locker) and deleted all my widgets. I'll report later if this was the key. BTW what about the screen settings for the brightness? I've set my brightness to 40% static.
[Galaxy S II General] TheGhost1233:
What kind of router do you have? Your drain is to high to be just the android-os bug.
[Galaxy S II General] lindsaytheflint:
I haven't looked at the brightness, as I've been troubleshooting the drain issue purely for when the phone is in standby (i.e. screen off). My display is set to automatic brightness.
[Galaxy S II General] lindsaytheflint:
My home WiFi router is not the issue. I only have WiFi enabled for a few hours each day, but my drain is always. My tests included disabling all network connections.

A drain of 30-60% (i.e. resulting in 40-70% left after 8 hours from a 100% charge) is typical of the kind of issues a lot of people have been having. If it wasn't so bad, so many of us wouldn't be so desperate to have it fixed. And yes, my battery usage in both the built-in battery tracking, & SystemPanel, both indicate "Android OS".
[Galaxy S II General] CandyAndy:
Hmm..it could be because I also have high drain and I currently have 13 widgets on my homescreens:Simple calendar, Simi Clock, Spotify, 7xHangping chinese, Snowstorm (update every 3h), CNN(update every 6h), Pure messenger(update every 6hours).

I wouldn't want to get rid of any of those widgets because after all these are the main difference compared to iPhone. What is the point of having Android if you just want the icons on your homescreen.

On the other hand I have been wondering one other issue with the battery drain. When I used to have Touch Pro 2, I used many different ROMs and there the battery was hugely affected by which radio it had. For example I live in Finland and if I used chinese rom with chinese radio the phone did work but the signal was never as good as with European/Finnish radio and also more drain affected.

I noticed similarity when updated to Hong Kong firmware, I didn't get so good signal in any place and I think I lost more battery.

Of course this isn't the whole solution if the battery drain is high also with the airplane mode. But for me even if I turn the data off and use only 2G I get pretty decent battery. So I think there is more than one problem effecting this.

I THINK that CNN widget might be quite bad for the battery..that I could try to get rid off..
[Galaxy S II General] TheGhost1233:
There have been plenty of reports of people with a specific router that, once connected just one time, will cause high drain until you do a factory reset. And yes it also displays under android-os but it's a second bug.
[Galaxy S II General] thegr8anand:
I lost 30% battery from 100 to 70 in 8 hours i slept. The only thing that was on was the yahoo mail push service. I deleted all the widgets that came pre-installed except the time/date one on the home screen. The phone was locked with screen off and brightness set to 0.

Is this normal? I have frozen a lot of samsung apps and services that are not needed.
[Galaxy S II General] djfatrod:
Maybe its launcher pro, I might try deleting that and see how it goes for a while
[Galaxy S II General] sunwee:
Hi TS,

good effort here. i am wondering, after you removed all the widget and experiencing better battery life, does Android OS still use high usage?

this is the first android phone that i notice Android OS taking up such a significant portion. all my previous phones, one hardly notices it's usage in the battery stats.
[Galaxy S II General] d3sm0nd:
Great list with tests! Although I don't think widgets are causing the high drain. It's something more deep underlying in the stock ROM... All working ROMs are based on the stock one and that's why we all have the Android OS bug.

I've seen people that report no Android OS drain on AOSP ROM (which someone only got booting, it's not usable but there is no battery drain). On the MUIUI ROM which we also got booting is also no battery drain...

What we can do now is WAITING... until we either 1. get a new updated ROM from samsung which solves the issue. or 2. we get a clean and stable CM7 ROM

Thanks my opinion...
[Galaxy S II General] aurelm:
Think I'm going to post this everywhere as there seems to be huge amout of people that blame poor battery life on this bug even if it's not the case.

The example of my phone:
[Galaxy S II General] lindsaytheflint:
Yes, next thing I was going to try was a different launcher. I may still try switch to TouchWiz, and putting on all my widgets. Launcher Pro doesn't have any such issues with other Android phones I've had, but there may be something in the SGS2 code that causes an incompatibility.
[Galaxy S II General] lindsaytheflint:
After removing the widgets, Android OS is no longer high. Other things are now higher (such as when I use the phone etc) which is what you'd expect in Android.

I agree with you - I haven't had this issue on other phones either.

(TS?)
[Galaxy S II General] lindsaytheflint:
I agree - I don't believe the widgets are the cause, but I do think having widgets is triggering the high drain. Something in Samsung's build is doing it.

I'm sure on a AOSP, MIUI, or CM7 the issue won't occur. It doesn't occur on proper builds on other phones. Just something in Samsung's build.

Definitely looking forward to a working non-Samsung build! :)
[Galaxy S II General] pik1:
Personally I doubt, that the Battery usage stats from android give enough details about the battery usage. Therefore I think its misleading...

Btw, I am on stock rom KE7, no bug/drain here...
[Galaxy S II General] lindsaytheflint:
I'm not sure what this adds, or how it's relevant. I don't think you read my first post properly, or if I was unclear, then I apologise.

The issue I was having, was that my phone was discharging very rapidly, even under various different scenarios, including my phone display being switched off for 8 hours, and flight-mode being enabled, etc. After this 8 hours of non-use, the battery would have discharged by 30-60%, and the "Android OS" processes (specifically, "suspend" and "events") were taking up around 90% of the usage.

This thread is not about debating the existence of the "Android OS bug", nor about how to identify it. This thread is about testing to see what can be done to workaround the "bug".

I think you also missed my statement in the first post: "If you’re not interested, don’t read or write on this thread – save your time, and mine."
[Galaxy S II General] lindsaytheflint:
System Panel gives quite a bit of useful detail around things like CPU usage, which is a significant factor in battery usage.
[Galaxy S II General] CandyAndy:
It is actually interesting to see that there is Accu weather, AP mobile, digital clock and all those rest apps in the memory even thou I dont use them and never even opened them.

Sight...maybe I have to root the phone once again and freeze those apps after all even thou I was wishing that I could just keep my phone close to stock.
[Galaxy S II General] aurelm:
It wasn't adressed to you, however as with all battery drain threads a lot of people that do not actually have the issue but maybe others will popup and the discussion will degenerate. So it's better to have a clear image of what the bug looks like and what id does.

And thanks for the analysis, it's very good but unfortunately without proper patches to the kernel I don't think it will be solved. Yes, you can remove most of the trigger apps, but that leaves a dumbed down operating system and I don't think many people want that. I removed most of my trigger widgets and apps, the bug still appears (with less frequency). However I don't feel good about removing so many apps just because there is a bug in the operating system.

Btw, other phones have it also, like nexus. So it's not a samsung thing (The wi-fi sharing battery drain was one for instance and I removed the process).

Hopefully someone will extract the patches from the generic 2.3.4 and add them to a 2.3.3 kernel, because Samsung dosn't seem to care much abot sgs2 (most other samsung phones already have 2.3.4 and the bug seems to be gone).
[Galaxy S II General] heatfire:
well my problem with the "drainage" was the auto syncing that google did with my gmail.. removed it.. now it uses less then 1%/h when im at work.. before it was more like 2%.

with android os cpu time 26 minutes in 22hours..

in my small world i think its a problem that the syncing uses to much CPU power and unsleeps to much or something funny like that..

some ppl with drainage also install APK and use it to autokill.. well that will just auto-drain your battery even more..

and some whining i guess just ppl have to learn that an smartphone this size will allways drain battery fast if heavy used.. only solution is bigger battery..

its kinda like comparing the PC i use now.. my gaming PC.. uses 180watts right now to type this reply.

if i used my laptop it would use 20watt..
[Galaxy S II General] lindsaytheflint:
Yes, I agree, widgets are too valuable to give up. Just trying to find out how to get the battery life to what we should be getting, on the system we currently have at hand.

My HTC HD2 (running various ROMs) never had these issues, and had great battery life. I was running plenty of widgets on that, and it didn't have any "Android OS bug", even on earlier versions of Android.

Looking forward to a corrected build, but in the meantime, I want to be able to have battery life when I need it. I'll keep testing different widgets etc.
[Galaxy S II General] lindsaytheflint:
Fast drain if heavily used, yes, but it shouldn't be draining battery fast if it's barely being used - i.e., on standby, with flight-mode, doing nearly nothing. A better solution is to fix the code, but that's up to Samsung (or someone who can do something particularly clever), so I'm using a workaround. If others are affected and don't want to accept poor battery, try the workarounds.
[Galaxy S II General] aurelm:
The "android os bug" is ONLY on 2.3 (except 2.3.4) . I had a galaxy s 1 and the bug appeared when I upgraded to gingerbread. I had to revert to froyo, wich never had it. Now 2.3.4 is out for sgs 1 and the bug seems to have been fixed. Still waiting for 2.3.4 for sgs 2.

I would gladly revert to froyo on sgs 2 if there was one :)
[Galaxy S II General] aurelm:
Also the funny thing about workarounds. They all work until they don't :).

I found at least 10 workarounds until now, shouted happy that I fixed it and after 2-2 days the bug came back.

It's like the sgs 1 gps problem all over again :)

Even worse, if i charge my phone, while switched but wifi, Bt, data all turned off. only weather widget on home; when i wake up a icon displays 100% charged, so does the battery widget. the moment i unplug.... 15%.....!!!!!!!!!!!

whn i charge with phone switched off... its perfect!

any ideas?? whats happening?
