[Galaxy S I9000 Q&A, Help & Troubleshooting] smiles.smiley:
There are several possibilities.

*Your battery Calibration ran off after you flashed. Re-calibrate your battery.

*Note that ROMs or Kernels may cause this to happen.

*Your battery could be faulty and further usage would cause damage to your phone. (If your phone/battery heats up intensively during charging, check it out)

This possibilities are arranged by the most likeliness of what seems to be your issue. If battery calibration does not solve your issue, proceed to checking on your ROM/Kernel. And so on.
[Galaxy S I9000 Q&A, Help & Troubleshooting] claustrox:
Thank you all.

I changed wiped everithing , changed rom and kernel and this morning same problem.

I am going to recalibrate another time , after that I am thinking of buying a new battery.

Thank you guys

Hi!

I'm not asking how to remove the yellow triangle (I have a usb jig for this).

Is there a way to change that image with another of my choise?

Thanks,

L.
[Galaxy S II Q&A, Help & Troubleshooting] HellcatDroid:
Well, no and yes, I think.

No, because AFAIK that image is in the bootloader that fires up the actual kernel and boot sequence.

Yes, because you could mod the bootloader to contain a new image, but you only ONE shot at this, as when you corrupt the bootloader to a point where it doesn't work anymore, the phone is broken beyond DIJ repair and must be sent in.

You really don't wanna go there.

Just remove it and use a custom bootlogo/-animation at kernel boottime.
[Galaxy S II Q&A, Help & Troubleshooting] volpe71:
Indeed I don't.

Thanks,

L.
[Galaxy Tab 10.1 Accessories] Entropy512:
There are plenty of alternatives. A solder blob and a resistor turns an iPad charger into a Tab 10.1 charger. There's also a good possibility that a kernel tweak will allow the Tab 10.1 to use unmodified iPad chargers (I just need to find if there are separate ADC channels for D+ and D-)

There is NO reason why any iPad charger could damage the Tab - USB is USB is USB, 5 volts is 5 volts is 5 volts. Samsung's weird detection resistors violate the USB Battery Charging standard (so do iDevices for that matter), and it is purely a racket to milk money from users.

Your views on OEM chargers are archaic and date back to the days when dumphones were so dumb that charge control intelligence was in the charger/power supply and not in the phone itself. This hasn't been valid for 95%+ of phones for years, and isn't valid for 99% of the devices that are discussed here on XDA, if any. These days, if a battery in a smartphone or tablet gets damaged by improper charging, the device itself and only the device is to blame, because all charge control intelligence has been moved into the device.
[Galaxy Tab 10.1 Accessories] djchad72:
I disagree. I bought non standard non OEM wall charger and cables for a Palm Pre. That was only 2 years ago. It fried both batteries and my battery charger pack. The batteries would degrade quickly upon operation and random reboots crept up. Techs examined the batteries and they tested bad. They had to replace.

I know there are 3rd party makers that can be trusted. But in the end the OEM and end user is going to only take so much before replacement get bothersome.
[Galaxy Tab 10.1 Accessories] Entropy512:
The only thing I can think of there is that the charger was weak and browned out, potentially confusing the phone's charging circuit.

Either that or the charger was SERIOUSLY defective. I'll be honest - before using a charger I do check that it is at least regulating to around 5 volts, so far I haven't had any surprises. The only surprise I've had were Monoprice "1A" chargers that were really only capable of 400-500 mA.

An iPad charger with the charging resistors tweaked so that D+ and D- are around 1.2 volts will be indistinguishable from the real deal for our tabs.
[General Topics] JayD94:
Hello, I was wondering if anyone has possession of this particular dock with the icons exactly like this, even the phone icon with the "phone" text next to it as well. Im assuming that i have to be on an HTC rom instead of a CM7 one to have that phone icon with text included, other wise it just shows the phone icon, i don't know?? Please help me guys, and I appreciate your time thanks.

Now we only need a CM7 Rom to go with it. Thanks for this.
[Atrix 4G Themes and Apps] Rikuumi:
almost cool
[Atrix 4G Themes and Apps] CaelanT:
Care to credit the creator?

Also might want to add which version of CWM this works with. You have the script for the new CWM in there, so I am assuming for people on 2.3.4 using Tenfar's new CWM?
[Atrix 4G Themes and Apps] madnav:
Yes it is for Tenfar's new CWM for unlocked atrix 4g.

I have done the needful.

I assumed the bootanimation.zip for cm7 would have been extractable from any cm7 rom and thus felt that the Original source may be cyanogenMod Team.

Nonetheless I have accredited the source I acquired it from. :)

I upgraded to HoneyStreak and decided to go back to stock. I followed the writeup here and was able to get it back. The only problem is that now I am on the T-mobile version, not the wifi only version. How do I fix this? Where can I find the stock roms for the WIFI only?

Never mind

doing more research I found this post. I don't know if it works yet since it will take 1.5 hours to download the required files. Thanks anyway.

Has anyone's market changed??? I am asking everyone I know but I am the only one around my area that has this...

Yes, that's the new Market that Google is rolling out. Most custom ROMs include it already, but it will eventually be pushed to all (2.2+) phones.

awesome... it's definitely alot cleaner than the older version.

Thanks for the response
[Verizon Droid Charge] Falcyn:
Yeah, it's a much nicer aesthetic... a little Windows Phone 7-ish with the tiles, but I'd consider that a good thing. Hopefully this is the beginning of a new look for the other Google apps, too... some of them need a makeover badly.

[Touch Pro2, Tilt 2 Android General] maff1989:
Here I am providing a link for a modified version of the 20110721 rootfs.img. But before anything else, allow me to explain exactly what was modified and why. And also, I'm running FRX07 with the default kernel it came with and the newest rootfs, OC'd to 614.4MHz (although OC doesn't play much factor in this tweak)

During the portion of the boot cycle when it loads the rootfs, at some point the read_ahead_kb (cache on the SD card) is set to 2,048KB as default with the newest rootfs. For higher-end SD cards, this is a good, wholesome number to work with..

With me, I'm running on a 2GB class 2, and using the program SD Booster (free), I was able to switch the read_ahead_kb while running Android. I tried multiple values and noticed the best results with 256KB.

Before with the 2048KB setting, the boot animation would cease a few times for probably a good 6-7 seconds, was terribly laggy throughout, and ultimately, from my experience, the performance of Android was impacted negatively. The system would literally halt while performing basic operations such as opening the Settings menu... although not all the time, still pretty annoying :\

By making this change in the rootfs.img, I noticed that the boot animation was MUCH MUCH smoother. I did not get the aforementioned problem at all using this rootfs.img with my SD card. And I also noticed a nice decrease in boot time, PLUS a pretty hefty boost in performance and stability after the boot ;) even more than when manually changing the value with SD Booster!

I know not all people are running on premium SD cards and that is pretty much the whole point of this thread: to provide people who DON'T have the best with something that could help with their performance.

And for the record, I'm no dev. I just know some bits and pieces and like to share my experiences. ;)

Please post feedback if it helps you!! It makes me feel better lol :D

ALSO: Before I even thought to post this, I made sure I uninstalled SD Booster to make sure it didn't apply any settings on boot, rebooted the phone into Android, reinstalled SD Booster, and noticed that it was no longer set to 2,048KB as default ;) doesn't hurt to double-check!!
[Touch Pro2, Tilt 2 Android General] highlandsun:
Since you're talking about a 1-line change, it would seem to me to have been far more efficient just to post the single line you changed, rather than make people download a multi-megabyte rootfs img file all over again.
[Touch Pro2, Tilt 2 Android General] maff1989:
Good point.. although most people like swapping rootfs.img's and making things easy, plus I already had the rootfs ready for myself.. I figured why not. ;)

But you're right, it would be helpful to know either way, so this is exactly what I did. I opened the init file within the rootfs.img (after mounting in Ubuntu) and searched for "read_ahead_kb" and found it. At the front of the line read: "echo 2048". That's the command that enables the 2,048KB SD cache during boot (the rest of the line I assume is to apply that setting to the SD card? Not sure..). I changed that value to 256KB, making that: "echo 256". Saved the file, unmounted the rootfs, and voila. :)
[Touch Pro2, Tilt 2 Android General] arrrghhh:
Interesting. I don't think my card would be considered 'premium', but it is a class4 card.

I'll see if this change makes any difference. IIRC this value was bumped in the newest build to provide better performance, not worse! I guess that's the tradeoff - better performance for some, worse for others... oh well. Thanks for your work!
[Touch Pro2, Tilt 2 Android General] maff1989:
You're very welcome :) I know the 256kb setting may not work better for all.. but I think this setting is key to how well Android performs on different cards.

Also, I DID notice that OC'ing is much more stable using this setting for my SD.. currently running at 768MHz and minimal instabilities. :)
[Touch Pro2, Tilt 2 Android General] fortunz:
I appreciate you posting the process you used to figure out optimal settings. I'm toggling between sd tools and sd booster as we speak. I'm still trying different settings. If my settings are different, that'll give me an excuse to figure out that virtualbox build I started on a few months ago.

EDIT: hmmm, I'm not sure sd tools is going to be a useful bench tool. 2 different runs on the same settings vary pretty wildly. I think the meter animations might be interfering with the testing. How did you decide which setting performed best while using sd booster? Were you just going with what felt best?
[Touch Pro2, Tilt 2 Android General] maff1989:
Personally, I never benchmarked my results.. I would change the kb setting in SD Booster to different values and resume normal operation of the phone (opening programs, checking for any abnormal "halts" during opening/closing animations and general program operation).

Basically, you're right; I found the best setting for my card based on trial-and-error and what felt right, then applied that setting in the rootfs to further increase performance over applying this setting AFTER boot.

Whichever setting feels right to you will most likely yield the best results. :)
[Touch Pro2, Tilt 2 Android General] championc:
Should I use DroidExplorer after booting the phone and then should I be looking for a file simply called "init" with no extension - or how do I do it ? It's just that I now see that a new rootfs 20110724 has just been released and since I'm sure it won't be the last, I'd like to know how best to edit these myself

C
[Touch Pro2, Tilt 2 Android General] maff1989:
Yes, the init file will be located in the "/" directory (where you find the /system and /data folders), and in that file, seach for "read_ahead_kb", and once you find that line, go to the bbeginning of that same line and change "echo 2048" to whichever value works best with your SD card.

Personally, I would use a program on the phone such as Root Explorer to modify the file, save, and reboot to have the effects instantly. That would simulate the same process I used to modify the rootfs in Ubuntu.
[Touch Pro2, Tilt 2 Android General] Starfox:
Gee, why all this complicated workaround for something easily done in one line inside froyo.user.conf...

echo "256" > /sys/devices/.....

-- Starfox
[Touch Pro2, Tilt 2 Android General] maff1989:
Um, it's not anymore complicated... Although my wording might have made it seem that way. The only difference was mounting the rootfs.img and changing the value in the init instead of the froyo.user.conf.
[Touch Pro2, Tilt 2 Android General] arrrghhh:
Well... the user.conf method probably is easier, considering you won't have to change it with any rootfs updates - you can swap rootfs', so long as that entry is in the user.conf file it will always get reapplied.
[Touch Pro2, Tilt 2 Android General] maff1989:
Yeah, that's true, since you put it that way lol. I was simply looking for the most direct way to apply the change, and the modding the rootfs seemed like the logical choice. Tbh I didn't know the user.conf was that significant.. besides applying some user-based settings and whatnot.

Boy I have a LOT to learn... ;)
[Touch Pro2, Tilt 2 Android General] arrrghhh:
You and me both! I still have quite a bit to learn about how Android has been pieced together on our phones. Doesn't help that I don't really know jack about Android itself :p.

The user.conf file is quite powerful, assuming you don't need stuff applied too early in the boot process...
[Touch Pro2, Tilt 2 Android General] maff1989:
For me, Android as an operating system is easy to understand, since it operates similarly to any computer system. But the fine details like how the rootfs, initrd.gz, kernel, and (most recently) the user.conf work puzzles me like no other. +1 for a Dev Learning Thread! :D

And yeah, the initrd.gz is what is loaded first, and to my knowledge it's that portion of the boot process that handles the Apps2Ext2/SD function... Fun little tidbit of info :)
[Touch Pro2, Tilt 2 Android General] Starfox:
You just need to study init (the file) to find out where everything is located, then adjust what you put into froyo.user.conf. Anything that is done before userinit.sh parses *.user.conf can be manipulated directly, anything after you need to get creative with sed or similar.

Initrd is the INITial Ram Disk. Basically, the kernel when loaded does not have enough to load the whole root/etc. so the initrd contains enough tools to get the kernel to recognize where the rootfs is and load it, then pivotroots with the real root then exec init.

App2sd has nothing to do with initrd. /sdcard/.android_secure, if you look in a real Android handset, is a world-unreadable/inaccessible directory. If you look closer, you notice it's been bind-mounted with those permission to "hide" the content. If you umount it, you have files named *.asec, which is a encrypted (to my knowledge) mini-fs containing the files for each program moved to SD. When Android boots it loopmounts each file to a dir in /mnt/asec or something. I don't think XDAndroid has the necessary stuff that goes through .android_secure yet.

-- Starfox
[Touch Pro2, Tilt 2 Android General] maff1989:
Thank you for the information, it's very enlightening :)

I mentioned Apps2SD because I owned an HD2 and was able to modify the initrd.gz to remove the Apps2SD functionality in a NAND Android ROM.. But thank you again for helping clarify any misunderstandings.

Also, if you have any links/bookmarks to online resources regarding these topics, I'd love for you to share cuz I'd hate to ask questions that could be answered with the right research. Plus, I'm sure you have better things to do with your time than to answer all the questions I have lol :)
[Touch Pro2, Tilt 2 Android General] großa:
Found this link here on XDA:

Increase Read Cache

I'm using SD Tools and SD Booster to change the cache and test the speed.

Got a class 6 card. Still playing around ;)
[Touch Pro2, Tilt 2 Android General] maff1989:
I have seen that link a while back; never could get that method to work, though I'm not saying that it doesn't. :)

From my experience, the difference between using SD Booster and applying the change to the rootfs/user.conf is that the read_ahead_kb, during boot, will impact the remainder of the boot process and furthermore, impact overall performance. That's why, for me, SD Booster simply wasn't cutting it. Although, it was VERY useful in helping me determine which value to place in the rootfs to get the best results.
[Touch Pro2, Tilt 2 Android General] fortunz:
I've been trying to find a more reliable objective benching tool since sdtools results seem almost random for me. That thread above suggests timing the opening of the gallery, but when I do, not all of the lag appears related to reading the contents of the card -- some of it seems tied up in animations. Anyone have any other ideas?

I actually might try overclocking temporarily if I can't find another card speed bench that less animated. I think the problem with me and sdtools is related to speedometer graphics. It hangs for 15-45 seconds at the beginning of the test while the needle makes its way painfully slowly to the first burst of speed read before continuing the test. Running multiple tests on 2048, 1024, 512 and 256 as set in sd booster, there was almost as much variation at each setting as there was between all the settings.
[Touch Pro2, Tilt 2 Android General] großa:
Yes that's true. No big difference if i'm using 892 or 8192. But I think (could be just imagination) that the gallery is a lot faster with 8192.

Will change the user.conf and see whats gonna happen.
[Touch Pro2, Tilt 2 Android General] fortunz:
Do report back as your experience grows, I'm certainly interested. I'm trying Antutu bench right now (custom, SD read write only). At least there's less animation, but I haven't tried it enough to see if the bench is consistent per setting.

Hello gui's!

i can modify my rootfs in windows? With the help of what program?

I try modify it with Notepad ++ but my android say kernel panic ))
[Touch Pro2, Tilt 2 Android General] arrrghhh:
Well you could modify the files within the .img with Notepad++.. but you need to extract the files within the .img file. I usually just mount -o loop it on a Linux box... not sure how you can expand this file on Windows...
[Touch Pro2, Tilt 2 Android General] aleks.spv:
Thnks arrrghhh!

In Windows to mount an ext loopback file need two program Ext2Fsd and FileDisk

Howto in the link

http://talk.maemo.org/showthread.php?t=27392

Now it is possible and on to experiment :)
[Touch Pro2, Tilt 2 Android General] arrrghhh:
Wow... could not be any easier in Linux.

If you want to continue development work, I highly encourage you find access to a Linux box. If you have a powerful enough machine, you can run it on a VM... VirtualBox is great.

"P.S. Even though Ext2 IFS for Windows supports writing to a ext2/ext3 filesystem, you might not be able to write to a virtual drive (i.e. your loopback file)." <--- That caveat especially makes me wonder why you would want to go through the trouble if you can't push your changes back...
[Touch Pro2, Tilt 2 Android General] aleks.spv:
Write is work, with Ext2Fsd and FileDisk i can change, edit, replace any file, parameters and etc.. in my loopback file

[Touch Pro2, Tilt 2 Android General] arrrghhh:
Ok, this is getting pretty OT. Glad you got it working... but

Dev work on this project is a heckuva lot easier on Linux. If you really need/want to get your hands into the bowels of this project, you will need a Linux box... of some sort. Enjoy!

[Touch Pro2, Tilt 2 Android General] großa:
I've closed background stuff with the advanced task killer and ran the benchmark (3 times in a row).

256kb Cache (fastest with 528Mhz in my case):

~6.9 write / ~13 read @528Mhz

~6.2 write / ~11.7 read @633Mhz

384kb Cache:

~6.4 write / ~12.5 read @528Mhz

~6.3 write / ~13.3 read @633Mhz

Gonna try it further and find the fastest value with 633Mhz.

633Mhz seem to be slower, but there are less halts while performing basic operations.

At least Antutu seems to work better (normally the second and third run are equal).
