[Vibrant Q&A, Help & Troubleshooting] test.im.09:
Hi,

I am new to android phone. I see on the Android development threads, there are multiple version of ROM

My question is what does a ROM consist of?

1. kernel

2. boot loader?

3. Apps comes with phone (e.g. Setting app, Phone app)

4. android framework

5. radio drivers?

6. gps drivers?

and my next question is for different version of ROM what are the differences?

I know some are porting CM9 some are porting vanilla android source.

But are these rom have the same kernel? same radio drivers /gps drivers/etc?

Thank you.
[Vibrant Q&A, Help & Troubleshooting] cashmundy:
A rom is a tar file, meaning an ancient and common type of Unix/Linux archive.

You can see exactly what is inside one by executing

tar -tf <rom>

You can even do this on your phone if you have a good rom.
[Vibrant Q&A, Help & Troubleshooting] bobshute:
first question the Vibrant roms usually have all you listed except for #2 bootloaders (with a very few exceptions)

Different roms will have different kernels, framework and gps libraries. there are a few radios to pick from.
[Vibrant Q&A, Help & Troubleshooting] danvsullivan:
Most ROMs have all of that, except sometimes the bootloaders. Major differences in the ROMs are the Android version, appearance and customization. Some ROMs have bugs, though, like GPS won't work or it take a while to connect to wifi. You can usually find out about these bugs if you read some of the comments on the ROM page.
[Vibrant Q&A, Help & Troubleshooting] test.im.09:
Thanks. The shipped ROM must have a working GPS, WiFi , Radio, Camera, Audio, Speaker, right?

But when I follow the 'Vibrant Development' threads for custom ROM, I see some ROM has GPS issue, others have Mute/unmute problem, wifi issue, etc etc.

My question is when creating these custom ROM, why can't one just copy these drivers from shipped ROM and have everything works?

Thanks.
[Vibrant Q&A, Help & Troubleshooting] bobshute:
The last shipped Rom for the Vibrant was a long time ago and was a 2.2 froyo rom. Everything will work if you choose a custom rom based on 2.2.

The drivers, libraries for 2.3.x Gingerbread and 4.0.x ICS don't exist for the Vibrant so the devs mix and match libraries from other phones and old 2.2 stuff.

Sometimes it works, other time not. It's incredable we even have a working ICS despite the bugs.

Might be more of a google market question, but thought I would start here.

I have 1 MT4GS with 90 or so apps, getting a second MT4GS. Most apps are market, but some from other spots. Is there a way to massively update/download the apps I have on current phone to new phone. In the past, I have just downloaded them one at a time from market.

Thanks in advance...
[T-Mobile myTouch 4G Slide] xdaznx:
Possibly

Just an idea, you could make a backup of your current mt4gs and then restore it on the new one? Ive never tried it but I dont see why it wouldnt work :cool:
[T-Mobile myTouch 4G Slide] leoilios:
Your google account should keep record of your downloaded apps and redownload on the next device you sign in on... Usually...
[T-Mobile myTouch 4G Slide] daviddallas:
Backup to the SD card OR some other form, like using a backup/restart App?
[T-Mobile myTouch 4G Slide] daviddallas:
I know with previous phones this didn't work. I would connect to my same account with the new phone, but it wouldn't show that I had apps loaded. Example, the eBay app would not show installed, I would have to load like it was a new app install. It would be great if that would do that, or it would show 90 updates to be applied. But I haven't done this in a while, maybe newand improved market will allow. I guess I will find out when I get receive the 2nd phone.

Thanks..
[T-Mobile myTouch 4G Slide] marc12868:
Well if your rooted and your next phone is rooted then you can use titanium backup to backup all your apps. If you CWM installed on both then you can make a nandroid backup and either restore it on the new one or use appextractor to restore the apps. But if your not then your best bet is let Google restore the apps that it does and manually resinstall the ones that it doesn't.
[T-Mobile myTouch 4G Slide] polarbearmc:
all of your payed for apps will certainly appear in the market under my apps and you can just go thru clicking on them one after another after another. the ones that were free though, i dont know any quick/easy way. i'm sure theres an app that will track all your downloaded apps regardless of if they were free or not.
[T-Mobile myTouch 4G Slide] Ohgami_Ichiro:
The market website actually keeps a log of every app you downloaded. You can then send them right to your phone from there.
[T-Mobile myTouch 4G Slide] daviddallas:
This is what I'm seeing, it show my paid for apps, but not the freebees. FYI - first phone is not rooted, second one is..

I also logged into google and google market on the pc hoping to see 'my apps', but no luck there..

So looks like a download at a time..

Thanks all for your inputs...
[T-Mobile myTouch 4G Slide] Ohgami_Ichiro:
That is odd. I still have stuff on the Web Based Market list that I haven't used since my old craptastic Behold II 2 years ago.
[T-Mobile myTouch 4G Slide] jsyi84:
I've done this before with my old MT4G. I would just flash a backup of my previous phone onto my warranty replacements... So I can say it does work....
[T-Mobile myTouch 4G Slide] daviddallas:
roms make a difference

I have been trying out different roms and they act different with Market.

These 2 work like I mentioend before, only show bought apps:

Bulletproof

Doubleshot Lite 1.2.4

But this one does an auto download of all my past downloaded apps, very cool.

Hi guys,

I am on RocketRom v22 with Abyss 3.7.

Today I wanted to launch SamsungApps for the first time. I agreed on the License Agreement and was forced to update Samsung Apps and so I did. But after the download was finished the app was just closed. If I try to start it again, it closes again.

What I already tried:

Clear Data in Settings > apps. --> doesnt work

Then, I uninstalled Samsung Apps with Tit.Backup and tried to install Samsungapps.apk provided by many sites, including XDA.

During installation I get the error "Application was not installed".

I hope you can help me.

Hi Guys...

Sorry to sound dumb, but I am new to the android scene blah blah... Just flashed CM10 (4.1.1 JellyBean) on to my GT-N7000, as you probably guessed, Samsung Apps isn't there.

I have read above but cannot seem to copy the SamsungApps.apk into my system/apps folder... It says SamsungApps.apk cannot be moved (using ES File Explorer)

Any help? Thanks.

EDIT...

Please ignore me... I had to change some settings in ES to allow root access. Thanks.

Double EDIT...

It's still not working for me though... Any help would be great.

[Eee Pad Transformer General] asdfuogh:
So, I will be starting my phd for physics next year, and I am ready to replace my crappy HP laptop. The thing is, what will be the best thing to partner with my Asus Transformer? I'm looking for people with experience pairing the TF with a desktop vs people pairing it with a laptop.
[Eee Pad Transformer General] munsterrr:
I am a firm believer that they both have their respectable spots in life. I would say for a student. Still get the laptop. A tablet doesnt replace ALL mobility needs that you will face. Unless of course you are a splashtop fan and get the keyboard dock. That may work but not a guarantee, ya know.
[Eee Pad Transformer General] asdfuogh:
I have a TF+dock combo already. Do you have experience using your TF with a desktop/laptop? I tried splashtop with my HP before, but it was laggy as hell, though I don't know if it's because my HP sucked or if it's because it's the laptop, or if it's the splashtop app that sucks..
[Eee Pad Transformer General] kookooktchoo:
TF+desktop

When I first got my TF, my ****ty HP laptop became a ****tier HP desktop since it never moved from it's dust spot on my desk. Every mobile application (not app) I needed the laptop for was replaced with the TF.

The only thing the laptop had over the TF was that it had an actual desktop OS, which I replaced with an actual desktop. I am much happier with the better everything I get from a desktop when I need it (keyboard, display, speakers, storage, etc.) and the better mobility I get from the TF when I need it.
[Eee Pad Transformer General] asdfuogh:
Same, my HP laptop never gets moved, though I still need it atm for matlab or labview occasionally.. So I'm guessing there aren't much pros to a laptop with the portability of this tablet huh.
[HTC EVO 3D] TheFlatulentFox:
I was trying to flash a AOSP rom for my evo3D, used GUI flash app to flash the kernel and then flashed the AOSP rom. it was hanging on HTC screen. I've read somewhere if it does this the kernel does not support that ROM. so I restored my backup and when i did I had no wifi (running viperROM sense). I know that was because of the AOSP kernel I flashed, I used the same program and flashed the sprint stock kernel and restored my back up once again. it just hangs on the Htc screen now. my back-up no longer works.

1. is there anyway to flash a kernel using fastboot (I have 1.50 unlocked)?

update:

flashed a new recovery hoping it will change my kernel back (restored backup). it does not hang on the HTC screen anymore. but now its just a black screen, I am getting the received text sounds. when i press on the power button the home, menu, back, and search lights go on but not the screen.
[HTC EVO 3D] k2buckley:
I haven't used the flash image gui app, so I don't have experience with it to say what might have gone wrong with the flash. However, if I were you, I would try booting your phone into recovery using fastboot. It sounds like something didn't flash right, and by booting into recovery using fastboot, you'll ensure that your boot.img (the part that has the kernel) flashes properly. So have a fresh copy of the rom you want to flash. Connect your phone to computer, and adb reboot bootloader. Then you should be in fastboot, and it'll say fastboot usb on your phone. (make sure you're in the folder that has a copy of your recovery.img) and type fastboot boot recovery.img. That will boot you to recovery. From that point, just flash the rom like normal. No need to flash the kernel separately. After you flash the rom, just try booting before flashing anything else, and see if it works.
[HTC EVO 3D] TheFlatulentFox:
I will try this.

update: I did what you told me and I restored my old backup. Thank you!
[HTC EVO 3D] joeykrim:
I not only wrote the tool in question, Flash Image GUI, but have used it many many times on quite a few different devices and can speak to the specific process/steps followed in the OP.

I'm going to try and take a different approach to answering this post than I normally do, let me know if this makes sense.

There are essentially three sets of files which need to be loaded on the device in order for the device to boot properly and everything operate properly. By loading these three sets of files, there will be no stuck on htc boot screen and no wifi doesnt work issues.

1) The kernel

2) The kernel modules

3) The system files for the Android OS, slang term, ROM.

If any of these three sets of files have any type of conflict, there will be problems. From the standard recovery boot mode, HTC unlock only allows 2 of the above three sets of files to be flashed. By blocking one of the three sets of files from being loaded, HTC allows the system to easily get out of sync resulting in random boot issues, WiFi issues, etc.

In addition to these issues, even if all three files are properly loaded, if any of them are incompatible with any one of the other, there will be issues.

The key to avoiding issues is making sure all three of these sets of files are one, loaded properly and two compatible.

Flash Image GUI, loads the kernel and the kernel modules, but due to Linux/Android system limitations, is not able to load the system files. The recovery mode with HTC unlock loads both the kernel modules and the system files but is not able to load the kernel.

When using Flash Image GUI first, the kernel and the kernel modules both get loaded. Booting directly into the recovery will allow the system files to be loaded and the kernel modules will get reloaded.

As long as the kernel, kernel modules and system files (ROM) are all compatible, there should be no issues with this process. If somebody wants to experiment grab a kernel and match with a ROM, then we return to the two key points, make sure they are loaded properly and that they are all compatible.

Regarding how to restore a backup, if you refer back to the OP in the Flash Image GUI thread, there are steps at the bottom of the OP under the Troubleshooting section which show the proper process. I've quoted them below and bolded the needed action, for your convenience:

Hopefully this makes sense. Let me know if you still have questions. I'm writing this off the top of my head but trying to think through it from a different angle so things are clear and organized.
[HTC EVO 3D] TheFlatulentFox:
that must have been my mistake, the kernel modules and ROM were not compatible. thanks joeykrim and k2buckley

Change it as you desire. You probably have it set to turn wi-fi off when the screen turns off (default setting).

[LG Nitro HD] S1XXV:
Sorry to hear that things aren't working. I'm not up to date with netgear routers but just search for IP lease time, it could be in the dhcp settings for the router. As far as my profile picture goes that was a picture that my ex girlfriend took, I think its funny.

[Atrix 4G Q&A, Help & Troubleshooting] SaladOA:
Universal Serial Bus is a standard. In Europe that means that all USB wall chargers have to be more or less the same. I use an Amazon Kindle charger with my Atrix just fine. Have also previously used chargers from other Android devices, WP7 devices and Blackberries.

[Atrix 4G Q&A, Help & Troubleshooting] J0s3f:
All proper chargers work fine on mine!

DON'T use cheap 1$ china chargers! They often have badly stabilized voltage and can even destroy your devices!

While on devices with proper stabilisation the voltage should look like the topmost graphic on this image (even under full load), on cheap devices it often looks like the one on the bottom, or something inbetween!

Also, some very cheap chargers allow the device to draw too much current, while grilling some internal components of the device. This could even start a fire!

(file courtesy of wikimedia)

For cables, you can use the cheapest! I never had a cable break in a way it could destroy anything besides itself, and I always buy cheap cables from www.dealextreme.com!

I can recommend this cable. Very solid build quality, better than most cables for 10€ around here!

Funny, my front-mounted USB ports (which put out just about 500mA) do a fine job for most devices including my Atrix. However, do not try to charge from dead via USB. For that you really need the full-power AC adapter. I use one from a previous phone at work (Samsung I think) and it charges in no time.

Just for information.

I recently bought HTC Evo 3D for my wife and installed a self-made 5V/3A charger in her car. The charger converts 12V in-car to 5V/3A stable.

I immediately was stuck with a problem. Whenever I put her Evo 3D it charges nicely. But my Atrix don't.

I remembered there is something special in Atrix USB toward charging. I checked and found that adding 10K resistor between white (receive or transmit?) and red (+5V) wires let my Atrix charges as it should be.

10K resistor has no effect in HTC.
