you sure nothing happens? try pushing down alt hard and keep holding it.. than press down on L hard see if a list pops up.. it only like 3 choices..
[G1 Q&A, Help & Troubleshooting] FireRaider:
Nothing, hold down Alt and then press and hold L. No changes.

The other odd thing is now when I do the camera+power combo it takes me to the welcome screen instead of the HBOOT screen. I was going to try reflashing the image on the external SD card and now it wont do that either.

The return+power combo also takes me to the welcome screen now.

The welcome screen is where I want to be except the 'safe mode' seems to be keeping the keyboard from functioning?
[G1 Q&A, Help & Troubleshooting] ldrifta:
what welcome screen? lol
[G1 Q&A, Help & Troubleshooting] ldrifta:
are the keys sticking maybe? lol
[G1 Q&A, Help & Troubleshooting] FireRaider:
First I get the T-Mobile G1 screen.

then the Android guy

then the Welcome to T-MobileG1, touch the android to begin.

That all seems normal to me, except for teh grey box that says 'safe mode' in the corner.

So i touch the android and it moves to the Setting upp your T-mobile G1 screen and wants me to enter my account info, which I cannot do because the keyboard is not funtioning properly. Its almost like the image flash borked the keyboard drivers or something.
[G1 Q&A, Help & Troubleshooting] FireRaider:
the d, e ,f , x keys are all working so I think its not a stuck key. no other keys seem to work though. nor the menu buttons.
[G1 Q&A, Help & Troubleshooting] FireRaider:
would safe mode mean some of the drivers are disabled? kind of like on a desktop computer?

And if so, how to get out of safe mode?
[G1 Q&A, Help & Troubleshooting] ldrifta:
uhhh i never even been on safe mode.. is the led blue while its on? my advice would be to unroot but you cant get recovery functioning properly so im not sure what to do.. do you know what radio and hboot you have?
[G1 Q&A, Help & Troubleshooting] ldrifta:
does it go to safe mode when you just boot up normally?
[G1 Q&A, Help & Troubleshooting] FireRaider:
Yes, safe mode shows in the bottom left corner of the screen when I power up normally.

I should have writen down what radio and such as I saw it displayed when I was in HBOOT and installing the DREAIMG.nbh file but I didnt think to.

Now I am either getting the Welcome to T-mobile screen or the first step of the recovery screen depending on the button combo I use.

But I am unable to proceed to do anything useful.
[G1 Q&A, Help & Troubleshooting] FireRaider:
Update

So apparently the phone was running CM7 and had an issue of some sort.

The owner placed DREAIMG on a micro SD and couldnt get it to do anything. I inherited the phone and got it into HBOOT and flashed the DREAIMG. The image file was of the stock ROM, or so I was told.

I know on my Galaxy S the CM7 uses a whole new boot loader, and you cant just reflash back to stock without going through some additional stepps. I think CM7 is ext4 and stock is ext3 or something?

Could this be part of the problem?And if so, how do we fix it?
[G1 Q&A, Help & Troubleshooting] ldrifta:
well im just not sure how there was a cm rom on there with no custom recovery.. uhhhmm only thing i know about is unrooting through recovery.. your ext has nothing to do with it, but if you can.. try to remove all files from sd card.. but keep the card in your device and than try power on with camera+power
[G1 Q&A, Help & Troubleshooting] FireRaider:
the micro SD only has the image file on it.

However!, I plugged it into my xp desktop and its says usb device not recognized like it was doing.

But... once i turned it on it went through the multi colored HTC bootloader screen that i recognize from my Tilts. And now its back to the HBOOT screen where I can press the power button to start update image. But the power button had no result.

So I unplugged, pulled the battery, and the micro SD, rebooted while plugged in and it will stay on bootloader screen. HBOOT is 0.95.0000 and radio is 1.22.12.29
[G1 Q&A, Help & Troubleshooting] FireRaider:
replacing the micro sd and rebooting while plugged into the usb cable gives me a quick view of the bootloader screen and then it sees the DREAIMG file on the SD and wants me to select action or power but neither button has any effect.
[G1 Q&A, Help & Troubleshooting] ldrifta:
so it says to press power to apply update, and when yu press it nothing happens..? hmm maybe try a diff DREAIMG.nbh file.. can you try recovery again and see if it works..?
[G1 Q&A, Help & Troubleshooting] FireRaider:
ya, nothing happens. and the screen is different from when I successfully flashed the image this morning.

I got rid of the safe mode notification temporarily but it comes back every time I reboot. I think maybe the menu key is stuck down? would that cause the rest of the keyboard to fail?
[G1 Q&A, Help & Troubleshooting] ldrifta:
yes if any button is stuck it can mess your phone up.. i suggest trying to clean the buttons or something than trying it again.
[G1 Q&A, Help & Troubleshooting] FireRaider:
Fixed!

I tore it completely apart and cleaned everything with achohol wipes and compressed air.

Put it back together, and it works fine now!

Thanks for the advice and suggestions.

I will leave it stock for a few days and then flash something new onto it.

Thanks again. :)

[Galaxy S II Q&A, Help & Troubleshooting] appro77:
Has there been any resolution to the 1 - 2 second wake up lag yet? I've seen several "fixes" like reducing the resolution of the lock screen wallpaper etc but none of these work for me. I've experienced the lag on KE7 stock ROM, Cognition ROM, Villain ROM and now on Lite'ning ROM.

Not sure if I agree that it's being caused by the CPU clocking down when the phone is asleep either. When I use SetCPU to set the minimum clock speed to 1.2Ghz the wake up lag is still there.

Also the lag does not occur when the phone is plugged in and SetCPU is telling me that the phone still clocks down to 200Mhz when asleep and plugged in.

Someone must have some idea what is causing this #$%$## lag.
[Galaxy S II Q&A, Help & Troubleshooting] DruNKfuX:
I use Softlocker Free for this.. Works perfect for me, a bit reduced battery life but not enough to stop me from using it..
[Galaxy S II Q&A, Help & Troubleshooting] appro77:
Thanks for the reply. I tried Softlocker a while back and found the battery drain pretty heavy. Might give it another go. I was thinking there must be a permanent fix for this lag problem though. Hopefully it's just a matter of someone finding it.
[Galaxy S II Q&A, Help & Troubleshooting] blue265:
I also noticed the lag on my old i9000 as soon as I updated to GB so know this is across the different samsung models on GB in addition to SGS2. I really do think its the clock going down despite your setcpu settings. Use cpuspy free from market and you will see what I mean. Once its in standby it goes into deep sleep which I believe is lower than 200? But set it to 1200 min and see if cpuspy logs it as going below that just to see

It will happen on every rom right now since they are all based on the firmware. I really think it saves battery going into that clock mode and if someone comes up with a fix the cpu will have to run at a higher clock rate and battery loss will be significantly higher

I've tried this app,and it did seem work. I'll try to see how about the drain of power.
[Galaxy S II Q&A, Help & Troubleshooting] appro77:
I was using No Lock and it didn't make any difference. What is really annoying me about this is that some users are seeing the lag and others apparently aren't. The lag on my phone is probably about 1 second. This isn't a really big deal unless this sort of thing annoys you. My iPhone didn't have the lag, my Desire didn't have the lag and I feel a high end phone like this shouldn't have the lag either.
[Galaxy S II Q&A, Help & Troubleshooting] appro77:

[Galaxy S II Q&A, Help & Troubleshooting] djsaad1:
do you guys get lag when using the power button? I get a small lag when using the home button, but if use the power button its instant.
[Galaxy S II Q&A, Help & Troubleshooting] appro77:
There seems to be nearly as many combinations of symptoms as there are phones. :) Mine has the same 1s or so lag regardless of how I wake it up. I tried SoftLocker again. Not only does it chew the battery, it was randomly causing my phone not to wake up at all, which then required a reboot. Softlocker has since been uninstalled.

The lag definitely doesn't show itself if the phone is plugged in or if music is playing in the background. Also if the phone has only been asleep for 5 or 10 seconds the lag is generally not there.... but not always. This seems to be inconsistent.

Then there are the fortunate users who aren't seeing the lag at all..... unless of course they are failing to mention that they have something running in the background like the music player that is stopping the phone going into deep sleep.

All I know for sure is that it's a PITA that Samsung needs to address. Given that I've read it was an issue with the S, I'm not holding my breath on that one though. :mad:
[Galaxy S II Q&A, Help & Troubleshooting] AnDruid:
Don't want to fork/derail the thread, but are you guys experiencing only the "Wake Up Lag" or also the lag when pressing the Home button while unlocked. I see some lag when using the home button to go back to Homescreen 1 for example. In case you folks are seeing lag in both the cases like me, could it be that both have the same underlying cause.

There is this other theory about the bundled Voice Talk app from Vlingo having the shortcut of Home button double tap, which causes any Home button tap to wait until the double tap window before doing its thing. I don't see that mentioned in this thread, but it kind of makes sense for the Home button lag, but perhaps not so much for the Wake lag (at least I could not think of a reason for that to happen). What do you guys think about both these problems?
[Galaxy S II Q&A, Help & Troubleshooting] ithehappy:
Well well finally users are reporting this problem, good to see its not only me.

Anyway, I don't think the Phone goes to any underclocked frequency when it goes to sleep. Cause if you can test SetCPU by setting it to 200 MHz then you will notice that in 200 MHz the phone turns itself off, you have to turn it on manually. So the problem is related with firmware definitely. And there are no fortunate users, some users don't take this as a problem, some don't notice it and some notice but doesn't agree, but here or there everyone has the bug. I hope the issue will be fixed in future firmware upgrade.

Regards.

[Galaxy S II Q&A, Help & Troubleshooting] rdy2go:
It may seem crazy but...

The delay depends heavily on the lock image you choose for lock screen.

With stock image it's instant, with custom background it slows down significantly.

My theory is that custom image is being resized while low Cpu frequency, it takes a while.
[Galaxy S II Q&A, Help & Troubleshooting] Robboftw:
I've just tested that, it's the same no matter what background I use.
[Galaxy S II Q&A, Help & Troubleshooting] MasK:
Wow..

Seems like the thread I can finally count on! Lots of behavior that I experience as well. I have the home button lag and the wake up lag and it's bugging me.

One thing to note.. The wake up lag is worse when you have an SD card inserted -> This scenario was the same for the SGS1 too. Anyone can confirm this?

I'm using No Lock as personal preference but the lag is always there. All behavior you guys mention (abt headphones plugged in, charging, within 5-10secs) are all being observed.

Eagerly waiting for a fix!
[Galaxy S II Q&A, Help & Troubleshooting] TheBishopOfSoho:
I had lag on my first SGS2, but it was worse that yours, at about 9-10 seconds (that's no exaggeration) plus high battery drain (Only getting about 6-7 hours battery at normal use). Went and got a new S2, no lag, and battery lasts 36 hours now.

It may not be the case with yours that its faulty, but I think I fixed the first SGS2 by flashing a newer rom, then doing hard reset and clearing cache's. I now have 2 shiny new SGS2's working as normal.
[Galaxy S II Q&A, Help & Troubleshooting] MasK:
I did flash a newer ROM, but didn't do a hard reset.. all my apps were intact. Perhaps I will spend sometime on it this weekend. By the way, which ROM did you flash on your first SGS2 that fixed the problem?

Also, I tried SoftLocker and it works!! The only downside is the battery life. I loose about 4-5% per hour while I was asleep. That bring me to say that the delay is not caused by the voice input function, but rather due to the device going into deep sleep (which may be normal). But it's the waking up that's taking long.

Still seeking for more ideas...:rolleyes:
[Galaxy S II Q&A, Help & Troubleshooting] appro77:
Yes, I found that SoftLocker is not really a solution because of the battery drain and some other bugs it introduced.

Anyone who is experiencing this lag should be contacting Samsung. I contacted Samsung Australia and they told me they had not heard of the problem. If everyone who is experiencing the problem reported it to Samsung, I think there may be a far better chance of a fix. Anyone who is annoyed by this bug, please email Samsung via the link on their website. If they are flooded with complaints they "may" act and provide a fix.

[Galaxy S II Q&A, Help & Troubleshooting] minidou-77:
You're totally wrong

It used to work fine while on GB
[Galaxy S II Q&A, Help & Troubleshooting] czesiu:
Maybe it is hard with this hardware, but as minidou-77 mentioned it was better with GB
[Galaxy S II Q&A, Help & Troubleshooting] MarekD:
I can confirm that. I'm on GB for daily usage and was testing several ICS builds for past few weeks and ALL of them were about half a second slower in wakeup. Of course SoftLocker can help with that but in my case the price of battery drain was to high (I'm a heavy user with Skype video calls and generally a lot of screen usage).

Free though: I’m a professional in it IT business for over a decade now so I know a bit. What I can’t get is how this issue can exist at all? To wake a CPU from a deep sleep you need single CPU cycle to order hardware to change state. If the CPU is working at 1MHz (back to the 80s? ;->) it should require 1/1000000 of a second. I know I know, there are more lines of code to process but seriously, 1,5 second in best case?! Came on Samsung, you can do better than that!

Anyway, GB can handle it in a acceptable manner while ICS obviously can’t. Too bad. I’m staying with GB therefore.
[Galaxy S II Q&A, Help & Troubleshooting] cichy3000:
it's really annoying, and it's hard to believe if You compare the old HTC Desire and newer SGS 2... Desire is so fast in waking up...

[Galaxy S II Q&A, Help & Troubleshooting] Visentinel:
In my experience and I have the phone since December 2011 before ICS came out the wake lag was always present, under ICS now it might sometimes be worse, but in no way would the wake lag go "unnoticed" unless this was your first smartphone.

Please tell me how other brand phones preserve battery life without wakeup lag.

It's not exactly sgs2 has amazing battery life compared to other phones.
[Galaxy S II Q&A, Help & Troubleshooting] Pfeffernuss:
No. Wake-up lag on GB is 650ms at least, as determined by the Exynos CPU ramp-up speed. Impossible to have a quicker wake-up than that (when not on the charger of course).
[Galaxy S II Q&A, Help & Troubleshooting] MarekD:
It is definitely not a future. For me it is clear that this is a bug and a large one. It looks like there is a bunch of incompetent programmers in Samsung and when they cannot find another way to reduce battery consumption they use some horribly slow procedure for deep sleep. I still love the phone and can live with this minor delay (at GB) but let’s be honest: we all would very much appreciate if it's gone.

---------- Post added at 10:59 AM ---------- Previous post was at 10:54 AM ----------

Thanx for clearing this up! 650ms is totally acceptable for me. Using GB i measured about 1sec delay while ICS was half of a sec worse so it looks like there is some room for optimization :-)
[Galaxy S II Q&A, Help & Troubleshooting] czesiu:

---------- Post added at 01:37 PM ---------- Previous post was at 01:36 PM ----------

not true, other phones use deep sleep and work normally
[Galaxy S II Q&A, Help & Troubleshooting] Pfeffernuss:
Just said so, because that's the way the Exynos CPU works.

With Exynos? S3 is even slower to wake up.
[Galaxy S II Q&A, Help & Troubleshooting] xmfpdlemalnz@hotmail.com:
on ICS it even became slower.

Takes good 2 seconds to wake the phone up.

It is actually very annoying now.

Dev please mod this 'feature'
[Galaxy S II Q&A, Help & Troubleshooting] htc9420:
Entropy512 demoed that it takes at least 650ms to wake up the modem because of bad implementation of HW. Deeper logging is quite impossible since the logging methods were removed from the kernel. I've personally taken this issue to some G engineers but they have no control over Sammy coders/HW architects. It's not processor dependent, it's the way SOC buses are initialized. The deep sleep issue is only partial true, every device has to achieve deep sleep in order to preserve battery, but the real issue is how the HW wakes up and how the buses are handled.

PS. Somehow, some people don't have it. Ask Intratech.Besides that, the cherry is the S3: over 1 full sec. Way to go, Sammy. Congrats on how you show the users their devices have deep sleep despite worse battery life.

[Galaxy S II Q&A, Help & Troubleshooting] TheSniperFan:
Yeah, it won't go away, but there still is room for optimization. There is no denying that it got considerably worse under ICS. Many people (including myself) have experienced the difference between GB and ICS.
