[Android Q&A, Help & Troubleshooting] Geddup:
Hey everyone,

I'm pretty new to this scene and I'm looking to get a semi-technical understanding of the boot process that an Android device takes. I've done the searches and found the articles, threads, blogs and this is what I've found so far. I appreciate any answers at all that anyone can give

Here is my understanding:

1. Power-on Device

2. Boot ROM is executed from known location in System ROM and loads the First Stage Loader into RAM.

However, RAM has yet to be initialized, right?

Also, am I correct in assuming the Boot ROM and First Stage Loader are two separate things?

3. First Stage Loader (aka "Radio" which contains baseband firmware) is executed and initializes radio hardware (Cell, GPS, Bluetooth, WiFi, etc)

4. First Stage Loader loads Second Stage Loader into RAM

Second Stage Loader is also known as the SPL, correct?

Is HBOOT a Second Stage Bootloader? I have seen conflicting/contradicting information on this.

How similar is Second Stage Bootloader to GRUB?

5. Second Stage Loader will either boot to the "System" partition by default, but also has an option to boot to the "Recovery" partition should the user decide to.

(To be continued...)

How accurate is all this information?

Thank you guys very much, I really appreciate your help.

i want to put my phone under warranty with carphone warehouse UK but i flashed my phone to a different firmware, can someone let me know what is the latest carphone warehouse firmware..

my phone version is..

PDA: i9100XWKI4

is there a way I can get back to stock? and will i still be able to get official updates from kies?

In the sticky of general is links to most threads of interest "use" the thread "original firmware" CSC: CWP is in there full firmware and kernel, I'm mobile at mo so no links but defo there as I've got a copy from their prior to root as always a good idea..

Hi, i want to provide a site (with enough of space and traffic ;) to all developers around mobile devices. I dont like hotfile, rapidshare, multistaff.... etc. So i want to do something good i think for us all (as a developer i just start to learning so i want to help in this other way)

I need some advice about what soft i can use what will be best i was thinking about simple wordpress page with file upload plugin, maybe somebody know a specific soft i can use on it and will be better for developers?
[Off-topic] adammwhiles:
I really think this area is already saturated and there are so many options out there now that it's not needed. Some just choose the wrong provider for the file. You would also experience huge bandwidth issues and probably incur a lot of overages. Many hosting companies ban sites that share files at that level because of so much bandwidth being used. You would need a dedicated server for this. Wordpress would not be a good idea just for security purposes, you would be better off writing your own PHP script to handle it or use one that already exist. just my 2 cents
[Off-topic] mobvision:
I have a dedicated server and im able to carry one bandwidth and storage... But problem is with a software now im checking 3 paid scripts for software repository working like a download.com or simillar. But I will be happy if someone give me some suggestions or advices.

If you're running an asop rom, it might have come with the "dev tools" app. Try enabling the cursor position and having a go at recreating the bug while taking note of the position monitors.

Ps: the seller said that it has 2.3.6 stock rom
[Nexus S Q&A, Help & Troubleshooting] Feeshie:
Always wipe when flashing a new ROM
[Nexus S Q&A, Help & Troubleshooting] bmt25:
CWM right sir? Thankyou!
[Nexus S Q&A, Help & Troubleshooting] frutelaken:
In CWM, yes.

Once you've booted in CWM you have a few menu options. One of them is wipe, where you'll be able to wipe data (applications and user data, = factory reset), cache and dalvik cache. Wipe all three, install MIUI ROM.

[Nexus S Q&A, Help & Troubleshooting] swaipa:
Hi, I wouldn't recommend running 1.54GHz on a daily basis, for most Nexus S's it's just not stable.

But lucky for you, KelLMSKing's MIUI and Brainmasters MIUI are both nice and smooth at 1GHz, and you can allways go to 1.2 or 1.3.

Good luck mate.. ;-)

PS. Most custom roms come with superuser preinstalled. But check the rom description.
[Nexus S Q&A, Help & Troubleshooting] bmt25:
I cant find any kernels with 1.3 sir
[Nexus S Q&A, Help & Troubleshooting] albundy2010:
There is a Trinity 1.3 ghz kernel.

There is no need to root first. It actually makes no sense at all unless you want to make a backup of your rooted stock rom. Otherwise you don't root the rom just to wipe and flash a pre rooted rom in the next step.
[Samsung Galaxy Nexus] whyamihere:
As the Official car mount isn't out till January and currently costs £50 (no way am I paying that much) I decided to go down the cheapo route. So as the Nokia CR-115 proved popular with GS2 users and the Nexus is only 1.8mm wider I ordered one at £5.88.

Can't get any pictures of it in daylight till the weekend so here they are at night.

Out of the box it's an extremely tight fit with the Nexus, but trimming down the generously sized 'cushions' allows for a better fit.

As you'd expect of a Nokia product, it's well designed and built well.
[Samsung Galaxy Nexus] AverageCanadian:
Looks pretty good. I much more prefer the official case design, but not $70 more. haha
[Samsung Galaxy Nexus] mingoid:
Looks like a good idea for me until Brodit release their model. Does it not press the volume button though?

Nope.

Yeah I had room to spare with the rubber using this case.

[HTC Flyer, EVO View 4G] joebob2385:
Given my (extremely) rural location and my lack of funds, I was somewhat forced into purchasing a view instead of a flyer. Best buy wasn't planning an immediate restock. Amazon was extremely overpriced. Oddly enough, a "32 gig 3g refurbished flyer" became available and fell into my price range. Given that it came with all the extras I needed such as the scribe, I jumped on the opportunity. However, the seller immediately emailed me notifying me it was the view. I accepted.

To make a long story short. I don't, nor will I ever have a sprint line. I am only using it for wifi.

Would it be possible to port roms from the flyer over to the view and it work, with all things considered?
[HTC Flyer, EVO View 4G] Snow_fox:
It is hard to say how easy it will be to port it.

One problem I think that your going to have is that there isn't an overwhelming support for the flyer to begin with, and I think it was the more popular HTC tab.

With that said, if you managed to get a good price on the view, I would probably just roll with it, if it has nearly the quality of the flyer.
[HTC Flyer, EVO View 4G] globatron:
Possible, probably yes...but practical no. It wold require far more effort than it's worth. I'm my opinon it would be better to wait for honeycomb and ask for the features you're looking for from Contradude or others if they apprear. Porting ROM features is a much more achievable goal than porting entire ROMs.
[HTC Flyer, EVO View 4G] joebob2385:
I already own the view.
[HTC Flyer, EVO View 4G] joebob2385:
Actually globatron, you are the very person I wanted to talk to. You have roms based off the official releases. In the thread with over 30 pages of replies, you mentioned that a view specific version was soon to come.

I'm all but desperate for honeycomb. I don't have a wireless network at home. I have no use for the net features. However, I really need that extra pen functionality that honeycomb offers. That and the ability to use honeycomb apps.

The features I need ported over is honeycomb itself.
[HTC Flyer, EVO View 4G] globatron:
Both Contradude and myself are trying all avenues to get our hands on a HC leak for the view, however this is proving extremely difficult. We know an official release is close but everyone we have spoken to is too afraid for their job to leak it. I would not ask anyone to take that risk but I do not think anything sane coule be ported any quicker than it would take to wait for the official release.
[HTC Flyer, EVO View 4G] joebob2385:
I definitely appreciate the effort and all the information. I wouldn't ask anyone to sacrifice their jobs either. I'm just sad to be left in the dark.

I may be forced to do some experimenting on my own until something does surface.

Again, thank you for the help thus far.
[HTC Flyer, EVO View 4G] globatron:
whatever you do, don't load a flyer hboot.
[HTC Flyer, EVO View 4G] m00nelph:
it's awesome to hear there is HC hope for us few View users out there, can't wait to be able to use the all the cool art apps out there like sketchbook with the pen! :D
[HTC Flyer, EVO View 4G] joebob2385:
That's exactly what I'm talking about. I really could care less about aosp on this device. My only source of internet is on my fascinate which won't even tether to my view. I can side load anything I really need. I honestly just want to see my view reach its true potential. I can't afford something like a cintiq. I'm trying to work my way up to that point. How can I accomplish that if my digitizer only works sometimes? How can i even access PhotoShop touch or sketchbook pro?

Hurry up and wait... That's the name of the game.
[HTC Flyer, EVO View 4G] brashmadcap:
Confirmation

So you have confirmation that HC is coming? I'm hearing so many mixed messages on this that I'm getting uneasy and thinking that my recent purchase was likely a mistake. Thanks!
[HTC Flyer, EVO View 4G] oldpueblo:

[HTC Flyer, EVO View 4G] joebob2385:
Android is suppose to be the Linux of the phone world... Considering, it technically is. Why all the run-around? Why is it so hard to get things going for the software? I'm getting tired of all the drama between proprietary hardware, carrier retardation, and false promises of releases that never happen. At least when they are suppose to.

Look at the galaxy nexus. After a decade with Verizon, I am ready to abandon ship due to their back-stabbing business practices, and non-existent marketing strategy. I love android and hope it is prosperous for years to come, but the hoops that everyone has to jump through is getting ridiculous.

Flyer Roms on View

Like the OP, I grabbed a brand new View Cheap. I have no need for the 3G / 4G. I will always be wifi only.

I was under the impression, the View WAS the flyer with a 4G radio... I had assumed that flashing a Flyer rom would work, but 4G wouldn't work because Flyer roms are missing those features. (I'm 100% fine with that)

Can anyone answer the following:

Will flashing a Flyer Rom brick the device? Hard or Soft Brick?

Has anyone tried flashing a Flyer rom on the View? Does it work?

Is the hardware actually different beyond the Radio?
[HTC Flyer, EVO View 4G] globatron:
Yes

Assuming (of course it has to be for custom roms) S-OFF it would be a soft brick

Take my word for it there is no point in trying it will not bot as it is.

Not really, but there are hboot, partition, address space, boot offsets and a few other things that are different. It's simply not feasible without a HC compatible view hboot.

Amazon has some apps for 10 cents as well. I came across it by accident and don't know how to find which ones.

I saw Paper Camera for 10 cents in the Market but when I clicked on it to purchase it said $1.99. So I searched for it at Amazon and they had it for 10 cents! It's a cool app, I like it, takes pics that look like a sketch plus other variations.
[HTC Rezound] xRogerxC:

I had that issue with another app, I just went back and clicked again and it worked fine in the market!!

I also noticed a bunch of apps for .10 on amazon.
[HTC Rezound] feralicious:
I recommend Paper Camera and Spirit HD which are up for 10 cents today.

I thought I wasn't going to put any games on my phone but Spirit HD is kind of cool.

After having seen that I was asked for some intrusive permissions when installing Paper Camera downloaded from Amazon and googling about it and finding out that if you take the Amazon app off your phone you can no longer use the apps you downloaded from Amazon I decided to uninstall it and install from Android Market. They didn't ask for the same access.

I saw a comment from a developer in an Amazon review of another app that Amazon has DRM so they require more permissions. I don't like that. And I don't think uninstalling the Amazon app should cause me to lose the ability to use apps I paid for!

just bought beautiful widgets from the 10 cent sale on my desktop (market.android.com) and selected to have the APK sent to my device, didn't show up. didn't install.

searched for the application in the market (on phone) and it shows as purchased, try to download it and get "The download of "Beautiful Widgets" was declined because you haven't purchased it" this is in spite of the desktop market telling me i've purchased it, 'my apps' saying i've purchased it and it saying i've purchased it when i search for the application.

any thoughts? the desktop market didn't even give me a chance to refund the purchase so i could try it straight on the device either.

I looked breifly but couldn't find the answer, and this may be a stupid question because I believe I know the answer. Since verizon no longer has an unlimited data plan, if you tether your device to a PC and use your 3g on the PC, does this take from your mobile data? I would imagine it would. Since I only have 2GB data allowance, I really need to watch how much I'm doing this, but wasn't 100% sure.
