Noooooo :(

I am SO happy with 1.8 (and previous), but I now suddenly have my first big issue;

I am at the office, and turn on WiFi for the first time, and I immediately got in a boot loop?!

How can I fix this?! (Please dont tell me to reflash or fastboot -w, everything worked PERFECT without a glitch, from start of 1.8 on!)
[GT540 Optimus Android Development] m4rtijn:
Well, I have some troubles too with my wifi! When I woke up, I've checked my phone and wanted to read the news, no wifi connection! In the menu's it says : "Disconnected"

It seems that the device doesn't find any wifi connection anymore, It was working fine yesterday and the week before (1.8), if I reflash a older backup than its working ok. Does someone know how to fix this?
[GT540 Optimus Android Development] mircea89fzr:
this happened once or happens everytime?
[GT540 Optimus Android Development] hackwerk:
I AM in a bootloop. Removing battery doesnt help. It comes to the pincode keypad, and then reboots over and over :(

I need help, now I am semi-bricked :/

Isnt it possible by fastboot/adb and edit/deleting the WiFi memory or so? Or at least turn it off?
[GT540 Optimus Android Development] despotovski01:
1. Remove the battery

2. Insert the battery

3. Boot in fastboot mode (POWER + CAMERA)

4. Type in order:

fastboot -w

fastboot erase system

fastboot erase boot

fastboot flash system system.img

fastboot flash boot boot.img

fastboot -w (just to make sure)

fastboot reboot

This should help.
[GT540 Optimus Android Development] hackwerk:
Dear Despo,

I know the procedure, this is how I got 1.8 in the 1st place, but I do not want to reflash and erase all, just because I pressed a button :/

All is working, I have tons of apps/configs/logins, but I just want to erase the WiFi-config file/memory and/or turn WiFi OFF (thats why it crashes now).
[GT540 Optimus Android Development] despotovski01:
Try just to reflash the system, without erasing the data. If it doesn't work, you'll have to erase the data.
[GT540 Optimus Android Development] eoghan2t7:
this is the only way to get you phone working again e.g. no crashing what you could do is take a recovery backup then flash the boot and system images once you have flashed them flash the data.img from recovery to see if that fixes it
[GT540 Optimus Android Development] hackwerk:
One of the following not an option?

1) Use adb or Clockwork Recovery (zip) to push/up a file (empty wifi config)?

2) Use adb shell to turn off WiFi by a certain command?

3) Option 1, but replace with wifi files from you guys (1.8)?
[GT540 Optimus Android Development] fishears:
well you could enter adb shell and do:

rm /data/misc/wifi/wpa_supplicant.conf

(not sure if you need to "su" first)

Best to "adb pull" that file off first so you have a backup - it contains your stored wifi settings

This might help, might not... but you could always push it back if it doesn't
[GT540 Optimus Android Development] hackwerk:
@Fishears; Nope, nothing helps :(

Update: I had to totally reflash because of pressing ONE BUTTON (Wifi on) @?##$#!@

Keep yáll posted...
[GT540 Optimus Android Development] maxgreece:
I am having horrendous problems with battery life on 1.8. I have done all the usual jobs (rm'ed the battery stats, ran the battery down to nothing etc. with no joy.

When making calls on the 3G network the battery drops from 90% to 60% in a 3 minute call.

Anyone else got this problem? Anyone got any ideas? Standby, no calls and no use gets through about 24 hours. Any use and that is instantly halved or worse.
[GT540 Optimus Android Development] MomirPeh:
Yea, it happens to me all the time, but only if the battery is around 95-90 percent. After a moderate call (even on 2G) it drops to 70-60 percent, but it drops from there very slowly. Generally I noticed that the battery drops slowly from 99-90, then rapidly to about 75%, then slowly to about 45% and then I look for a charge source. The battery lasted for about 2 days up to this point! I'm satisfied with this.

Battery Issues Fix

For all those having battery issues, I have been following all the comments & tips about it on this forum & I have been doing some experimenting over the last few months. And finally I have a working solution which has been working for me (see screenshot of my phone), it's been working now for 53hrs now & still at 45%. And I have been using the wireless at btw 4-6hrs per day & some long calls.

Here's what to do:

1. Drain your battery totally, put it on & off until it's totally drained (screen refuses to come on)

2. Charge it over night (a good 4-6 hours). It might also be good to unplug and re-plug a couple of times if it reaches 100% prematurely (Bump Charging).

3. Once the specified time has elapsed, without unplugging the phone from charge, go into (clockwork) recovery (from your reboot screen), go to advanced and, wipe your battery stats, then reboot. Once you click reboot, unplug your phone. And that's it!

Things to note: you must have one of the newer versions(versions 3+) of clockwork to go into recovery from full charge & develop the habit of charging your phone before it runs down completely . I hope this is helpful & compliments Mur4ik great work & Joost's wonderful thread :)
[GT540 Optimus Android Development] mind_challenge:
Battery issue

Well you've all been talking about pulling the charger out and then back in when it reaches 100%, well I've tried it, and here's what happened: It stayed on 100%, and when i connected the charger back in it rapidly dropped to 90%. I tried to repeat the procedure, hoping that it will charge back to 100%, but no, it fell down do 85%. At that point i stopped trying to charge it back to 100%. Anyone experienced this issue on 1.8?

edit: I've recently noticed that keyboard that is installed besides Android keyboard keeps switching off in settings after every reboot. Does anyone have similar problem?
[GT540 Optimus Android Development] :
Thanks edy4sure!! I have put it in the startpost

Joost
[GT540 Optimus Android Development] waydownsouth:
THIS might help explain why the battery drops after taking the phone off the charger...
[GT540 Optimus Android Development] EazyLuke:
@edy4sure:

The "uptime" doesn't really show how long your battery lasts. It just tells how long your phone has been switched on since the last reboot, no matter if you connect the charger or not.

To really show how long you are on battery since last charge, you must go to settings->about phone->battery use.

My battery lasts about 42-48h, I think that's okay.
[GT540 Optimus Android Development] edy4sure:
@ joost: You are most welcome!

@ waydownsouth: Thanks for the link it really confirms (to a certain extent) my method. So I guess I better start calling it "bump charging" then (take note Joost).

Also lets take note that:

* bump charging shouldn't be done everytime but on occassions when we notice that the battery's service is falling.

* Let me quote, Battery University, "Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory."
[GT540 Optimus Android Development] edy4sure:
Thank you for the correction, in my excitement I captured the wrong screen! So here is my actual battery stats:

After the drama of ruining my 1.8 installation (non-clean) by turning on WiFi, resulting in a boot loop (see last posts), a little status update:

I now reflashed 1.8, totally clean (with fastboot -w and erase), and no backups restored (system is totally unstable when recover).

All works and is smooth, 40 apps reinstalled, but 2 problems now occur:

1) I now have the battery problem for the first time ever (1.4, 1.4b, 1.5, 1.6 and 1.8 were ok). :(

2) Another problem is the crashing (FC) of GApps now and then.

Devs are probably trying not to bother with until we get an official froyo so that they don't have to keep redoing it.
[Epic 4G Q&A, Help & Troubleshooting] mkasick:
The linked module works in Eclair only. No one has built an Epic-specific tun.ko module for Froyo since we don't have the source code.

It's possible that a tun.ko module compiled from the same kernel version (2.6.32.9 ARMv7) will work even if it's not from the Epic source tree. I haven't bothered looking for one since I'm still running Eclair.

The Eclair module is attached to the second post of that thread.

Update Jan 31, 11:

Updated kernel with sound driver v4

View attachment 504817

Don't forget to update your Voodoo apk on market, to control all features!!

Updates of sound driver v4:

- add ADC 128x quality oversampling control

- fine-tuned FM radio volumes. DRC compress only to prevent saturation in non-standard case

- remove full_bitwidth SNR booster option (killer samples expose artifacts)

- restore high frequencies by allowing to control a filter and bump the input gain

- apply headphone amp levels only on media and FM radio

- mono downmix applied automatically at play, no more click at power up with 128x oversampling, improved code quality

More info on https://github.com/project-voodoo/linux_gt-i9000/commits/froyo-voodoo/

Old Jan 27, 11:

Updated kernel with sound driver v3 and new mono downmix option

View attachment 501826

You will also need to update the Voodoo apk.

Old (Jan 24, 11):

This is a port of voodoo's kernel to latin devices (I9000B), based on JPD version (JPM+Latin) with working DTV. :)

Included in this kernel:

- ClockworkMod 3

- Voodoo sound driver v2

- Voodoo color gamma 2.2 and mDNIe color and sharpness enhancements

- Voodoo lagfix

Unzip and flash with Odin (Windows) or Heimdall (Linux):

View attachment 498680

You will also need the Voodoo app to control the driver

Hello mantrajt,

This is only the kernel, the same of Vivo´s ROM plus add-ons. With this kernel you will be able to use the lagfix, color enhancements and the voodoo driver, that boost your sound experience with your I9000B Galaxy S.

Also have a modified recovery (ClockworkMod)

Just upload with Odin with PDA pointing to the tar image, and download the voodoo´s app.

Good luck!

SERIOUS BUG IN FLIGHT MODE! WHEN IS ACTIVATED IS IMPOSSIBLE DISABLE IT

PLEASE PACKET THE ORIGINAL KERNEL TO REINSTALL IT, I CAN'T GET OFF, THE FLIGHT MODE, IT DOES NOT RECOGNIZE SIM CARD[/SIZE

03:57AM

FIXED:

WHEN INSTALLED THE KERNEL I PUT THE PHONE IN FLIGHT MODE. FOR STRAGE REASONS, AFTER THAT, THE DEVICE CAN'T START THE PHONE APP AND HAVEN'T RECOGNIZED THE SIM CARD. FOR FIX THE PROBLEM REINSTALED OLD KERNEL BUT NOTHING. THEN REFLASHED PDA AND NOW IS WORKING.

DON'T KNOW WHAT WAS THE CAUSE OF THIS STRANGE BUG. I JUST WANT TO HELP, SO BE CAREFUL. AND IF YOU WANT, TRY FLIGHT MODE. YOU KNOW HOW FIX IT NOW.

04:01AM

CONFIRMED BUG WHEN FLIGHT MODE IS ACTIVATED, IT CAN'T BE DESACTIVATED. NEED TO REFLASH.

04:09

Reflashed (JPD JPD JPD + Unknown Kernel)

Dunno WTF, now flight mode problem again.

Reflashing just JPD...

(Really tired of SGS boot sound)

All working.

ULTIMATE FINAL HIPER MEGA LOVELY FIX FOR THIS BUG (for dummies):

0. Set Download Mode

1. FIRST RE-INSTALL JUST THE OLD KERNEL with Odin (without SD card and SIM card)

2. Reboot and hear the lovely sound of boot. (Check if it possibly to disable Flight Mode, if not, go to step 3)(without SD card and SIM card)

3. Shut Down Device

4. Set Download Mode

5. Reflash JPD-JPD-JPD Firmware with Odin(without SD card and SIM card)

6. Reboot and hear the lovely sound of boot again. (And check again to disable Flight mode, at this moment will be possible if yes, go to step 7, if not kill yourself, try again all the process or try with another kernel or fw)

7. Disable Flight Mode

8. Shut down device and put SD card, and SIM Card

9. Hear the lovely sound of boot

10. Enjoy your phone as if nothing had happened.

THIS KERNEL OR THIS FIX WILL NOT DELETE ANY USER DATA, SO DON'T WORRY.

PLEASE SOMEONE PACKET THE JPD KERNEL PLEASE.

The stock kernel is already packed @ post #8

But I really didn't understand your post. Did you tried to put your phone in flight mode and upload the stock kernel? Because it just occurred with your phone.

Anyway, why put your phone in Flight Mode if it won´t receive any calls in download mode? :)

Did you turned off any lagfix before upload the kernel?

Please compress the logs in /sdcard/Voodoo and upload. I think your phone is not with voodoo´s lagfix enable.

GPS

I had no several issues with GPS since I installed from Market GPSopt and GPS Booster. I did it even before installing JPA. Dont know exactly how much they help me, but had no GPS differences between JPA, JPA->JPD and now, with Voodoo.

I got (if outside) my lock within a few seconds, and it keeps locket. Ok, its not as fast as my old N1 (how I miss it), and not so accurate. But works very well. Used on the car, mounted on the windshield, also give me lock in a couple of seconds.

[Galaxy S I9000 Android Development] andifds:
1.The stock kernel is zip file that Odin not recognize, the changed to .tar and prints error.

2.I put your kernel, then booted phone. All working well.

Then I put Flight Mode (FOR TEST THAT MODE, NOT FOR FLASHIG OR ANYTHING ELSE, JUST TESTING). At this moment the phone app stops, and then the sim card is not recognized. Cheked with two other differents SIM cards. And tested at least 4 times, Reflashing, Rekerneling, Reflashing, Rekerneling....

Doesn't matter if you suht down and reboot. Flight mode stills ON but it's impossible to turn off. I've tried check networks settings but it says something like "Insert a SIM Card" but already had

I haven't any lagfix

[english too bad, sorry]
[Galaxy S I9000 Android Development] franks.maia:
Don't worry about your english, mine is bad too. The important is that we can understand each other :)

1. The only reason that I zipped the file is xda doesn't allow to upload tar images, so before upload the stock kernel or mine you need to unzip and point PDA in Odin to tar file.

I think this was the problem.

Try to upload my kernel after unzip the file, and tell me what happens.

Good luck!

Hey, franks.maia!

Mine is working ok, but it gets some random really annoying locks and is crashing applications more often as I use it.

Before installing this kernel I had Steam kernel installed with all partitions formated to jfs. Could be this? I reverted everything to rfs before installing the voodoo kernel but something should went wrong. Dunno... Maybe you could help.

And there is any way to get some overclocking with this kernel on future versions? It's hard to find kernels for i9000b with overclocking capability.

Sorry mate, I forgot to tar the zImage before upload, here is it now:

View attachment vjjpd.zip

I think this is a bug of your old kernel, tried 3 times and can't reproduce this error.

Why don't you try to update your ROM, with a .PIT file (803.pit), modem, CSC with repartition enable? (after backup your data, of course)

Here is the steps:

1. Follow this instructions: http://xdaforums.com/showthread.php?t=807886

2. Boot your phone, you will see that you can't touch your display, but don't worry, we just choose this rom (eur) due the repartition.

3. Upload the JPD ROM, with repartition unchecked.

Here is the link: http://www.multiupload.com/YJ6UH8XI0L

4. Now you have your phone clean, as new, with the stock JPD ROM.

5. Upload the voodoo kernel.

6. Enjoy :)
