Hi guys:

wireless Router: D-link Dir-600

SSID: on

wireless channel: 11

there is wireless router in my house. The laptop connects to internet by wireless

router, but Magic can't find wi-fi network in the same room. Wi-Fi in my Magic works right in other places with unknown wireless router.

is anybody have suggestion?:confused:
[Droid Incredible Q&A, Help & Troubleshooting] Akomack:
I recently rooted to the new cyanogenmod and in an attempt to fix the known wifi error I replaced my kernel. I thought I had a nandroid backup, but apparently not.. To make matters worse I tried to unroot and turn s-on. Well I got s-on and now I'm stuck with the htc splashscreen, I can get into bootloader and I still have clockworkmod installed. My question is, how can I get s-off (unrevoked won't see it because of lack of debugging) and also what could I do to get my kernel back on track (stock or pretty much anything that works).. I'm sorry if this is vague, I'm a pretty tech savvy person but I'm still newer on rooting android systems.
[Droid Incredible Q&A, Help & Troubleshooting] Grooby97:
best way is to follow step #2 here http://xdaforums.com/showthread.php?t=817487

that will get you back to stock.
[Droid Incredible Q&A, Help & Troubleshooting] sevascisum:
Pretty sure you can just mount your SD card in clockwork, then download the stock cyanogenmod kernel to your PC, transfer it to your phone, and install from there.
[Droid Incredible Q&A, Help & Troubleshooting] Ocelot13:
if you want s-off, just download unrevoked forever from the unrevoked site and install it in cwm (mount usb, transfer patch, apply)

now for fixes.

easiest would just be the install the correct kernel via cwm (again, you can mount usb in cwm, transfer new kernel, install it).

or, wipe everything in cwm, reinstall cyanogen and thus being back where you were before tinkering with the kernel.

another step..

use this tuturial to go back to stock

http://androidforums.com/incredible...16-how-revert-back-earlier-version-hboot.html

and youll be back at 2.2 stock (use the froyo ruu instead of the one in the link)

then you can reroot and do whatever youd like

[Droid Incredible Q&A, Help & Troubleshooting] Akomack:
Transferring the Cyanogenmod kernel worked, I kinda feel like an idiot for not trying that, figured with s-on I couldn't do it.. Wifi works now, which is what got me into this mess in the first place. Thanks for your input!

Just wanna know where to go after flashing my root. That way I know who to grab a zip file from when new updates from Sprint are rooted. Plain stock, no themes, no nothing, would even take a stripped version too w/ no Sprint apps if someone is running around making those.

[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
coming form other android phones, ive learned to wipe batt stats in recovery to get the best life.

normaly i wind up seeing voltage @ 100% a little over 4.260v

now on our phones we dont have that option, and i noticed while trying out diferent roms that its hitting " 100% " at various voltages depending on what the batt truely was when flashing.

if i recall the file is : /data/system/batterystats.bin that we need to delete? corect?

well, before i did it, it hit 100% @ 3.782v and wouldnt go any higher...

now, im sitting @4.246... im not 100% sure its fully charged. ill let it sit overnight turned off and see where i wind up.

UPDATE 11-20

SO, voltages have been confirmed.

100% = 4.20-4.25 depending on battery condition

0%= dependent on the kernel generaly 3.2-3.0 {found some as high as 3.7v!} thank you to hastarin for pointing the files out

if your not seeing 4.2v your not getting full battery life.
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
sure enough, i was sitting just shy of 4.3v this am after an overnight charge with the phone turned off...
[HD2 Android Q&A, Help & Troubleshooting and Genera] Slampisko:
Interesting info, but where would you find out the voltage the battery is producing?
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
so, how to wipe the battery stats?

time to get down and dirty and learn to navigate thru the android OS.

download and set up the android SDK

http://developer.android.com/sdk/index.html

heres a newbie guide to adb in the nexus forum

http://xdaforums.com/showthread.php?t=619153

for those less computer literate, you can use droid explorer to do alot of the stuff thru a GUI. it also will set up adb for you.

http://de.codeplex.com/

the code that you type in to remove the battery stats is

rm data/system/batterystats.bin

now to properly condition the battery.

turn off the phone, plug it in, preferably overnight.

boot the phone up while still pluged in.

delete the batterystats.bin file ether thru adb or terminal

drain the battery fully, untill it powers down. wait a min or two and reboot it to completely drain it.

congrats... your phone now knows corect voltage values for 100% and dead.

Remember: Flashing a new Android build erases the battery stats, and automaticly rebuilds them based on voltages it see's .

ie: you need to recondition after each flash to get max battery life.

i use the "battery life" widget by curvefish to show me temp, voltage etc.
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
some builds will show actual voltage under menu/about phone/battery use

otherwise i use the " battery life" widget by curvefish, available for free from the market. once you add it to the screen, tap it, hit settings, then check both charging info and extended info.
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
after conditioning the battery, im currently @27 hours since unplugging, gps, and wifi turned on the entire time, im @ 3.873v or 61%! granted, its been light usage its my secondary phone right now, but i am on the outskirts of service, and the week signal usualy sucks the battery...

ill update again , probably this time tomorow once it finaly dies...

just a little food for thought: its been over 27 hours since i unpluged, and my voltage is still higher than what the phone assumed was 100% @ the time of the initial flash....
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
@ 50 hours (still 10%) i finaly got sick of waiting for it to die. i turned screen on full bright, and ran gps test and locked the screen on. phone finaly died @ 2.988v im now charging it again with the phone turned off.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ZaZu90:
Umm why do we need this though ?

Wont the phone keep running as long as there is sufficient voltage in the battery ?

What is the use of this method ?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Reno_79:
This is for people who have found a build they are happy with and want to use for a while so that their battery lasts longer, much longer. As the OP has posted, his phone is currently lasting about as long as it does in WinMo which is an impressive feat, more so being as he's running his GPS non-stop at the same time.

I for one am going to do this myself when I get the time. If I knew whether my alarm would go off while the phone was switched off (for the overnight charge) I'd do it tonight but cannot risk being late for work tomorrow lol
[HD2 Android Q&A, Help & Troubleshooting and Genera] ZaZu90:
Thanks Reno but I meant HOW does it work ?

I thought this method just helps you see your battery's percentage .. Wont the battery run no matter what the percentage show as long as the battery has a charge ?

Can someone please explain this ?

Yeah I cant afford not waking up late as well, so im charging it while its on, would that affect anything ?

It will still charge up the battery wouldnt it ?
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
as stated in the op.... when you flash a build, android assumes whatever that voltage is =100% so if you realy only have 50% (about 3.7v) thats all it will charge to...

100% is realy 4.2v , this recalibrates it to alow it to fully charge.

do they not teach reading comprehension now a days? its not just this thread... its the whole forum!
[HD2 Android Q&A, Help & Troubleshooting and Genera] ZaZu90:
Oh ok thanks ! Makes sense ..

Well I charged my phone during the night while it was switched on, in the morning the battery stated it has 4.212mV

Do I need to recalibrate it ?
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
recalibrating cant hurt.
[HD2 Android Q&A, Help & Troubleshooting and Genera] ducvader:
For those of you who are using droidexplorer.... when right clicking on batterystats.bin and selecting delete the file does not disappear... is this how its suppose to be? If that is not suppose to happen then where exactly do you type "rm data/system/batterystats.bin"
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
in the console
[HD2 Android Q&A, Help & Troubleshooting and Genera] t1h5ta3:
for what its worth: Li-Io battery technology realy isnt different whether it be a phone, rc car, etc...

our batterys are a single cell. ie: rated 3.7v

4.2-4.25v is concidered by the industry as fully charged

3.7v is nominal voltage

3.2v "shorted" voltage : ie: voltage sag due to max discharge @nominal voltage

3.0v discharged

2.5v protection circuitry kicks in.

this jives with what i am now seeing on my phone after wipeing stats and calibrating...

it is also a industry standard to fully discharge ( 3.0v )about every 30 discharge cycles.

people please post what you are seeing for voltages 100/0 % before complaining about battery life.
[HD2 Android Q&A, Help & Troubleshooting and Genera] mattfmartin:
So this ^^^^ is the adb command?

Then I would type in

adb devices

rm data/system/batterystats.bin

Is this right,or is there any other commands I need after I put in adb devices?
[HD2 Android Q&A, Help & Troubleshooting and Genera] elitishtc:
very interesting

maybe i should try it..
[HD2 Android Q&A, Help & Troubleshooting and Genera] mattfmartin:
4.2v @100%
[HD2 Android Q&A, Help & Troubleshooting and Genera] Reno_79:
This is just a quick question from a bit of logical thinking really...

Once we've got a properly calibrated Batterystats.bin file, can we back that up and use it with other builds?

Can we also therefore share it with other peoples phones as well?
[HD2 Android Q&A, Help & Troubleshooting and Genera] E90 Commie:
I experienced something interesting a few days ago. I was forced to reflash my phone because of a destroyed data partition causing the reboot loop of death (it rebooted every time it tried to load Sense). After a successful reflash I got everything going but when it hit 34% indicated battery it switched off. And this time it was total - the battery was really depleted. So I put it on charge and rebooted. Now it read approx 15%.

Yesterday I experimented with the lowest possible level and it switched off with approx 3.5 V left according to CurrentWidget. I emptied the battery totally after that (so it switched off immediately - i.e unable to even start the boot sequence) and put it on charge.

After booting it read approx 3.6 V and approx 10% battery. I don´t believe it managed to get so much charge during less than a minute of charging. I didn´t delete the battstats.bin this time because I got the impression that it "recalibrated itself" after the switch off at 34% indication.

Now it seems (according to CurrentWidget) I got full charge at approx 4.2 V (4250 mV is the highest reading) and switch off at 3.5 V. It seems to be slightly better in the lower region but it would be good to be able to reach 3.2-3.3 V for switch off. It´s still able to do approx 2 almost full boot cycles (i.e load everything until it should load the launcher) before it switches off.
[HD2 Android Q&A, Help & Troubleshooting and Genera] obaidr:
woldnt it work if I just fully charge my battery, then delete the batt states in CWR und restart my battery with the phone unplugged. That should mean i have the highest voltage and the phone would recognize that as 100% which is true.

Hi I'm having trouble finding the batterystats.bin I'm using the ultimate Droid ram build so would the file be in a different place in a ram build oh and when I plug the charger in with the phone off it turns the phone back on so does anyone know if the phone would charge if I boot into crw and leave it for half hour to charge the last bit

[HD2 Android Q&A, Help & Troubleshooting and Genera] lude219:
Did you happen to switch to a different kernel perhaps? (refer to the first post)

I've tried on a few kernels and I can say that some shuts off at 32xx, some at 34xx...and the one im using now (GL_Core_v5b) shuts off at 35xxx. Usage hasn't changed much and the drainage from one kernel to the next is more or less, still the same at 3-4% after 8hr sleep. So it seems that the phone is drawing less voltage (more efficient?) and sustaining the same amount of time. I'm not that knowledgable in battery so I'm wondering the same thing as you, if the battery somehow drops down lower to 32xx, wouldn't that mean we get longer battery life? :o

So I've been doing this for the last 2 months and my battery dies within 10 hours and overnight, I lose 8% over 8 hours. This is what I do

1) Drain battery to 0% using transformers and google navigation. I then turn the phone back on immediately and wait for the battery to die three times to make sure it is completely drained.

2) Plug in the phone into my charger which turns the phone back on. Let it fully recharge.

3) When it's fully charged, I reboot the phone twice to make sure its 100%.

4) While plugged in still, I open android terminal and type in

su #enter

rm /data/system/batterystats.bin #enter

5) repeat 1-4 two more times.

6)Charge battery to 100%.

After step 6, the battery typically loses 6% per hour in idle for a few days. Around day 4, it moves to 1% an hour in idle (only if I am one location). Walking around school or driving home to school, i lose 15% an hour.

Am I doing something wrong?

Once, I did step 1-3, but in step 4, I unplugged the phone and wiped battery stats and the phone lost 1% an hour in idle. The problem is that I do not get a full day out of the phone, and when I surf the internet non stop, my battery drops 25% an hour.
[HD2 Android Q&A, Help & Troubleshooting and Genera] lude219:
What I found out is that it doesn't really matter which way you delete the batterystats.bin file (fully charged or around 1% when the battery about to shut off). Sounds like you probably have something syncing in the background or other processes running. Maybe update to a different kernel or run a stock android and see. I typically lose 2-3% after an 8hr sleep.

My stats - are they alright?

I have tried various methods of erasing the batterystats file (battery calibrator, CWM wipe battery stats), and here's what I'm getting:

Min range: 3406mV

Max range: 4194mV

Is that alright?

I can't seem to get over 4194 no matter what I do, and can't get under 3406, no matter what I do either.

Is there something I'm doing wrong? I've had the phone for over a year, I've always suffered from short battery life (12-15hrs max in light to moderate use).

And one last question: when I get the green light even with the phone turned off, should I still keep it plugged at least overnight? I mean, will or will not the battery stop charging when it gets green light with phone off?

Thanks for your answers.

From all the work that went on with the Nexus One battery calibrator app, the low voltage number is coded into the battery itself.

So, on a N1, with the right kernel, a non-cheapo imitation battery with the proper chip, and the Nexus battery calibrator program, you can reprogram the low voltage from 3.4 to ideally 3.2. Lets you squeeze out a little more from the battery before it autoshuts.
