[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
Let me apologize first of all as I come from 5 years of using Windows Mobile knwoing what I am doing (cooking ROMs included) and now just got my Galaxy /Android a couple weeks ago and am blank at all of it.

After messing up with some system files and (useless) stock applications (like I removed stk.apk and other stuff) I decided to do a full hardware reset as the phone started getting random crashes.

But after the full reset things only got dramatically worse. I quickly realized all the missing system apps are

still

missing (I thought they'd be "restored") and basically nothing works, just crashes one after the next, cant use anything.

So, a hardware system reset on the galaxy, doesnt really reset anything except user installed apps and settings... amazing:(

Can someone please tell me (the idiot here, I know) how to do a

real full restore

where all system files, all missing files and positively everything gets back in the Tab as it was originally?

What a flippin' nightmare... Thanks in advance very much!

deletion of Stk.apk causes FC's in phone and acore.

if you don't have a backup of this apk, download a rom (like Modaco or Overcome),

open with winzip and extract the Stk.zpk from system/app and push it to /system/app on your Tab using adb (remember set the permissions to 644 after push).

A hardreset NO restores deletions on /system

Note: Other files that are not deleteable in /system/app are: Browser.apk, Email.apk, TouchWiz30Launcher.apk and TwWallpaperChooser.apk

Note (2): For your convenience, i attach the Stk.apk file from Overcome-1.1.3. Try it

Note (3): In order to restore ALL system data and apps, you need to restore a full rom.
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
OK, first of all a big thanks for both file and info. Aside from the Stk.apk, the biggest thing that made me run into problems was trying to update my Contacts.apk:

http://xdaforums.com/showthread.php?t=907399

things didnt work out for me and even after restoring the original files (Contacts.apk and Contacts.odex) nothing really worked again, reason for wich I tried a system reset.

Now, do I need to re-root the Tab or its still rooted, and can I perform the operations easily with Root Explorer like I did before? You mentioned to use adb and set permissions to 644 after push but, sorry again for the ignorance, I have no clue what adb is nor what/how to set permissions. Pathetic to be ignorant huh?:(

My last 2 questions are, where could I find the original Contacts.apk and Contacts.odex and if needed a full ROM to do a total restore?... hopefully I wont need to get to that point?...

Thanks a million again.
[Galaxy Tab Q&A, Help & Troubleshooting] Deleted member 267841:
hi,

try to download overcome-1.1.3, and extract all the deleted apk's from system/app directory. push into the /system/app in your tab.

the apk's of overcome are deodexed (you don't need the .odex files). after that, wipe your data/cache and reboot.

if this don't works, try with roto rom
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
Hmmmm thanks again but I think Im beyond all this. I dont have a file manager on my system, just realized I deleted the useless stock one and had repalced it with Root Explorer and ES File Explorer. I have them on my External SD Card to install them again but withou a file manager or an app installer cant get to them. And I tried download an app installer from the Market and get Framework errors non-stop and downloads do not initialize... I think Im beyond a quick fix... how do I get my hands on a stock full ROM to restore everything... and how? What a nightmare... gotta tell you, I love Windows Mobile... I love it... never ran into anything like this in the past 5 years of using it... never...

Thanks again!

use "adb" in order to access to your tab from your desktop pc.
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
Cant. Dont even know if I need Kies installed or not (I did have it installed) but adb just asks me to connect the phone and thats it... its connected aready... this is desperating...
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
OK I did manage to connect with adb but, how to I install applications? I can navigate to my SD card where I have ES File Explorer and Root Explorer but dont seem to be able to install them... Also if i try to copy Stk.apk I get immediately an failute message... this is crazy...
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
OK so I managed to install ES File Explorer and Root Explorer with adb... crazy process. It seems my phone is still rooted after the reset. From the phone I copied Stk.apk back to /system/apps where it was before deleted.

But needless to say nothing got fixed... not sure if Stk.apk is now "actually" installed or just there in the folder. But still nothing works and crashes every 10 seconds... logs provider, dialer, phone, framework, contacts... its all a firework of crashes...
[Galaxy Tab Q&A, Help & Troubleshooting] foxmeister:
Given that you've hard reset your device already, you are pretty much wasting your time trying to "fix" what you broke by messing with /system, and you should really just flash another ROM.

My suggestion would be to follow the advice on this thread.

Dave
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
Yeap, that what i did and it was succesfull. My only issue is that Id like to convert my Tab's file system to ext4 to improve speed and performance and then update to the 1.4Ghz OC Kernel. I have no idea how to do those 2 things... actually Im not sure I understand the difference between a ROM and a Kernel... I assume a Kernel is part of the engine of the ROM itself but I have no idea how to perform the update. I read countless threads and its all scattered info without finding one straight to the point guide on how to do it...

Thanks again:)
[Galaxy Tab Q&A, Help & Troubleshooting] foxmeister:
Part of your problem is that you are trying to run before you can walk! Your experience with WinMo is of pretty much no use to you in the Linux/Android world, and until you get a better handle of how everything hands together you are always going to feel a little lost.

Personally, since your device is now up and running again, I'd suggest that you hold off doing anything else for while, until you get a chance to catch up with some of the basics. Once you are a little more familiar, you can then start with something simple like flashing the MoDaCo kernel (instructions here) to support EXT4, and to give you access to ClockworkMod recovery.

IMO, whilst EXT4 and O/C kernels will give you a performance boost, they are not as noticeable as jumping from a shipping ROM to one of the JMx development builds that Samsung has put out. If you are running JMI, you should already be feeling that the device has got much snappier.

Dave
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
Yes Dave you are right, right and right again!!! Thank you for the wisdom and advice!!!

The main thing I have understood with today's messy experience was that the actual ROM files are never deleted or damaged as long as you dont access them via a rooted tool and start deleting them. Now I understand that Titanium Backup, Sprint Backup (my favorite), My Backup Pro and others, only back-up and restore what the user installs on top of the ROM itself. So a full "reset" wipes all that data but leaves the ROM files as they always were. If they got damaged in the process, they'll still be damaged till a a full ROM restores all system data, now I get it.

What I still dont get is the issue of bakcing up and restoring. In Windows Mobile, a toll like SPB Backup has a simple option called FULL BACKUP and that backs-up everything on top of the ROM and then restores everything after a full reset on top of the ROM again like it was before. The problem I have with apps like Titanium Backup, Sprint Backup, My Backup Pro, etc... is that there is not a "BACKUP ALL" option... one has to backup "data", "settings", "apps" and I always feel stuff will be left behind and then not restored.

Till I find an app or way to do a simple one-click "backup everything" and then "restore evertything" I always feel vulnerable to changes I make to the Tab that may get it unstable or corrupt and then not being able to be restored properly without a full ROM Flash and then re-installing all from scratch.

With WinMo, I could do all sorts of crazy experiments and tweaking and after that, a registry restore or back-up restore would bring me back my phone to exactly like it was with all my stuff and configuration in a matter of seconds or minutes. Thats what I need to find out with this Tab/Android and then Im ready to be able to explore messing up with this knowing I can always easily go back within minutes to the state I had before with all my apps and settings.

This is what I need to learn next how to do! Trampoline without a safety net is not a good idea. Ive alwways loved WinMo for the ease of backing up and restoring whatever I was doing on my handsets withjout ever worrying to put myself at risk to loose it all. I need to learn this on Android and its definitely more intricate!
[Galaxy Tab Q&A, Help & Troubleshooting] instechgainza:
just put sdcard into your samsung tab and flash modaco kernel amd it will automatically covert to ext4, after that you can flash the 1.4ghz kernel you wanted.
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
Sorry, I cant follow you. I put an SD card in and flash modaco kernel? What files do I put on the sd card for this effect?...
[Galaxy Tab Q&A, Help & Troubleshooting] instechgainza:
no...you need a kernel to flash via odin, you need sdcard mounted so that it will backup all files automatically while converting to ext4..head over to modaco kernel section amd follow the instruction.
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
Where is the modaco kernel section you refer to? I can search for hours and find zilch... these blogs are endless...
[Galaxy Tab Q&A, Help & Troubleshooting] foxmeister:
What you want is a Nandroid backup, which you can only make from a recovery image like Clockworkmod recovery.

Essentially, this does exactly what you want, but you need to flash a new kernel (e.g. the MoDaCo kernel) which supports Clockwordmod.

Dave

i beg to differ about stk.apk fc's your phone. that's the first thing i delete when removing system apps with no fc's

refer to this link about having a bare bones system. stk.apk is for management of multiple sim cards

http://wiki.cyanogenmod.com/index.php?title=Barebones
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
When I delete stk.apk (for me useless useless useless) the first thing that happens immediately is that when I hang-up on a call made or received, the Tab vibrates then freezes for about 5 seconds then tells me the phone application has crashed. I tried this with 2 ROMs now as a test and its guaranteed. More even, if you use a program like SYSTEM APP REMOVER you can emulate the removal of an app by disabling it... it only takes me to disable STK and a reboot for the phone not to work. cant get rid of it, that simple:(
[Galaxy Tab Q&A, Help & Troubleshooting] VeEuzUKY:
Yes, I know. But after installing Rom Manager, there is no listing (yet) for a Flash Clockworkmod recovery for the Euro verison of the Tab. The closest thing is the AT&T (GSM) version but I not dare installing it so, cant use it.

hye i have a infuse 4g, and i recently downloaded root explorer after rooting my phone and i installed the systemUI.apk from the system/app folder and it took the status bar away and i thought it was cool for a bit but i noticed i have no notifications at all not even for calls, and so i deleted the systemUI. but it did not help, can someone please help me, email me at xshamsher.khan@gmail.com
[Galaxy Tab Q&A, Help & Troubleshooting] rangercaptain:
Do you realize you're not in the infuze forum? The best solution is flash a rom.

[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
I've got the same tmobile SIM card in my HD2 now that I had in my unlocked iphone, with the iphone I would get 2 bars average and loose about 5% battery in 8 hours. on the HD2 I get anywhere from no service to full bars. It's killing my battery, I'll loose 50% battery in 8 hours while I'm asleep, with wifi off. battery usage says its the cell service thats using it all. Should I flash to a different radio or what? thanks. I've tried different roms, no difference.
[HD2 Android Q&A, Help & Troubleshooting and Genera] SpiderVenom:
You can try different radio, that does help. If you have your phone in a poor reception area where it needs to constantly check for a better signal that will drain your battery as well, if that is the case you can just try toggling off 3g and that will extend your battery life.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
I actually have data off, it drained 50% while data was turned off. is there some info I can find on which radios are better for certain networks or areas maybe? the only thing I can think of is turning airplane mode on, I don't know what will happen to texts and voicemail though while airplane mode is enabled.
[HD2 Android Q&A, Help & Troubleshooting and Genera] SpiderVenom:
I don't really use airplane mode but I think your calls will go straight to voicemail and your texts won't go through until you turn airplane mode off. Not 100% on that though. as far as radio info you can check the master radio thread on the windows sub forum here

http://xdaforums.com/showthread.php?t=611787

Most people say 2.15 seems to be best. If nothing helps I'd suggest going back to wm and seeing what the drainage is like on that if it is still that bad it might actually be your battery itself.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Digital Outcast:
This is true. Airplane mode makes your phone a glorified MP3 player.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
thanks, I've currently got 2.15.50.14, I guess I will try Leo_RADIO_2.14.50.02**

what are all these radio downloads in that thread? whats the difference between the first set of links and the links I quoted below? are the links at the top and below compatible with the 1024LEO? thanks.
[HD2 Android Q&A, Help & Troubleshooting and Genera] squish099:
As long as its a x.xx.50 radio its compatible with our tmous hd2. Flashing a x.xx.51 radio will make it a paperweight..

Swyped from my Cyanogenmodded HD2
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
ok, thanks again, just flashed Leo_RADIO_2.14.50.02**

I read in another thread to let the battery go through 3 cycles before flashing to another radio, any word on this?
[HD2 Android Q&A, Help & Troubleshooting and Genera] huggs:
that's so you can best judge the effect on battery life, but flashing radios consecutively won't hurt your phone
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
I still seem to be going from full bars to no bars in my house where as my iphone would be steady at 2 bars. I guess I'll see how much drain I have tonight.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
if data is turned off, am I still using either a 2G or 3G network for calls? I'm wondering if seeing full bars is the edge network, and then seeing no service, or 1-2 bars is the 3G network, perhaps its still switching between 2G and 3G networks even though data is turned off?

if this is true, things would make sense cause my iphone couldnt get 3G on tmobile.
[HD2 Android Q&A, Help & Troubleshooting and Genera] upsmanraz:
This is a know problem with the network, not data dropping, when the phone is locked, aka sleep mode. The only thing you can do is go to settings, wireless and networks, mobile networks, uncheck mobile network first, and change network mode to GSM only. Until someone with the knowledge to do so can find a way to fix whatever is wrong in the us **.**.50.** radios, were sort of out of luck. If you have your APN set correctly, you will get the same data stream as you did on the iPhone, unfortunately edge. Emails will sync, weather will update, and facebook all that will work, but slowly.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
the new radio didnt help my battery life, going to see if using 2G only helps, even though I have data off.
[HD2 Android Q&A, Help & Troubleshooting and Genera] lukey-windy:
I am experiencing problems with this also, I can confirm that switching to 2G does stabilize it however I am still experiencing problems with signal drop. It is very annoying. I'm hoping a dev puts more attention to this than ROM making at the minute. When I get some spare time I am going to look myself.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
I don't have any mobile network first option
[HD2 Android Q&A, Help & Troubleshooting and Genera] upsmanraz:
Sorry about the misleading entry, when you go into setting, then wireless and networks, uncheck the checkbox next to Mobile network. Once the check mark clears then go just below to Mobile networks, and change Network mode to GSM only. As of now, this is the only way to eliminate the dreaded cell standby eating away your battery from trying to re-connect to the cellular network.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Gabe3:
I enabled use only 2G networks, with data off. only used about 8% of my battery while the phone was idle for 9 hours. with use only 2G networks disabled, I would use about 50% battery in 9 hours while I was asleep. so I guess my theory is fact, even with data disabled, its still switching between 2G and 3G networks because my house is in a poor 3G area. my signal goes from 2-4 bars now too. It hasn't lost signal yet cause its not trying to connect to 3G
[Galaxy 3 General] shuvabrata:
Hi,

If i enable auto-rotation from the home screen, the home screen also rotates automatically creating a lot of lag. Is ut possible that the home is never rotated (always in portrait) whereas applications can rotate the screen?

Please let me know. It would be of great help.

regards,

Nandi
[Galaxy 3 General] stubborn_d0nkey:
ok, so more info would have been helpul, you know. however, of course it is possible, this is android isn't it :P. You must have installed a different launcher since your home screen rotates. Look in the launcher settings, there should be a setting somewhere that will turn it off.

tl;dr launcher settings!
[Galaxy 3 General] shuvabrata:
This is Froyo rooted on my G3. And the option is in the notification bar drawer. So it isnt becasue of the launcher.
[Galaxy 3 General] stubborn_d0nkey:
did you even look!?!

Its the home screen! How can it not be launcher related!!

you are really frustrating, but I still explain it to you:

The same way that some other apps dont rotate, some launchers dont rotate, namely stock launcher. If you are using stock launcher the home screen wont rotate regardless of that option being checked or not!! Third party launchers provide the ability to rotate your homescreen! Most, if not all, will allow you to turn it off!!

Sooo go! Check your launcher settings!!

I'm using zeam and its under general. However, you are obviously not using zeam if you are complaining that it is slow.

Soooo go!! Check your launcher settings already!!

P.S. Depending on your launcher turning off rotation for the homescreen might include turning off rotation for the app drawer. I dont know if there are launchers that separate the two.

[Fascinate Android Development] StDevious:
i think punkkaos mentioned in one of his tweets that he was working on kernel, and got hardware acceleration on UI working but had graphical glitches, but he said that it was awesome fast.

[Fascinate Android Development] papstar:
Maybe I'm mislead, but doesn't the i9000 froyo kernel use an rfs filesystem?
[Fascinate Android Development] SirGatez:
I think the nexus s is the only recent Samsung phone not using rfs. The rfs drivers in this kernel are in the stock i9000 source.
[Fascinate Android Development] SirGatez:
I should have source up by the end of the day heading home from hospital now.

I did some googling, correct me if I am mistaken but I can not seem to find the kernel module source for s3c_bc, s3c_lcd, or pwrsrv outside of Eclair. The eclair module for pwrsrv fails to boot, and the sizes of all 3 compiled binaries do not come close to the froyo ones from samsung. Both s3c modulea are less that or about 100k in froyo, eclair and eclair compiled against froyo are closer to 300k each. PowerVR driver is like 350k on froyo, and eclair and eclair compiled against froyo are 1.8/1.9MB. I did find a newer powervr driver from imagination last night but have to rework some code make it compile, and ti has the most recent driver from imagination but will not share unless you purchased a 1,600 evaluation board.
[Fascinate Android Development] StDevious:
I can send a lot curse words TI's way atm.

Btw, how much performance do these drivers improve ?
[Fascinate Android Development] SirGatez:
3d accel nor graphics work without them. Sammies binary works as shown in the alpha posted but ti isnt to blame, imagination (imageon) makes and releases/licenses the driver and its code.

Just read an article saying they may opensource it in 3rd quarter this year :-p I dont see that hindering us much right now with froyo, we can always dissassemble and recompile the binaries if we are left no other options to ensure gingerbread compatibility. Nexus S binary modules should work for gb testers at the moment, not sure how different froyo and gb powervr sgx drivers are right now but their are seemingly major internal changes from eclair to froyo. Every google result says both use the same gpu.

But Samsung is to blame for the lack of opensource froyo s3c_bc and s3c_lcd modules. But they look portable to froyo at the moment, will delve deeper into rabbit hole soon...

Edit: I have not tried to boot without loading these modules but when I compile and use the eclair powervr driver for froyo it driver load loops then boot loops then shuts down. The phone may work in 2d without them but I am doubtful. The kernel does have enough internal code (s3c_fb, s3c_cfb, etc) to display the i9000 startup image but the rest of the drivers are supposed to load before the bootanimation plays.
[Fascinate Android Development] StDevious:
Damn, that's neat info. Where does one go to learn all this neat stuff about kernel, decompiling binaries and then compiling them again for another OS ?
