[Milestone XT720 General] CrystalShield:
Hello everybody,

I have a question about bootloader. I have searched before I asked. But most of the thing I got is something for someone who've already know what bootloader is.

So my first question is "What is bootloader?"

And everybody here seem to be happy with any manufacturers that they unlock the bootloader.

So my second question is "What will we get/earn when the bootloader is unlocked" or "What a unlocked bootloader can do?"

Or if my question is common and boring, please send me a link, or a page or something that I can get my answer.

I've searched before I asked but any information I got is for people who already know what it is, like bootloader update news or something new to do with bootloader.

Thank you.
[Milestone XT720 General] mediaon:
"What is bootloader?"

in my understanding the phone company doesn't want the customers to install other roms beside the official rom provide by themself so they make "bootloader " as the "key code" to protect from installing other rom the official roms sbf

"What will we get/earn when the bootloader is unlocked" or "What a unlocked bootloader can do?"

the developers can totally modify and control and test and make us more roms ..you can install and exprience more roms (OS)with more features such as Miui ,cynagonmod nad many others

now that our XT720's bootloader is locked so the devs can only modify with limitation and can only make our rom base on old kernel..is bootloader is unlocked..they can get us more rom with newer or better kernel
[Milestone XT720 General] try-and-error:
The locked bootloader prevents using a custom kernel. So we can only use the original one. The kernel itself cannot be optimized or customized. So we can get features like swap support only using fastboot with usb connection to PC.
[Milestone XT720 General] Mioze7Ae:
Additionally, the bootloader is the phone's version of BIOS if that helps. Unfortunately, there is a lot of misinformation out there. I used to be very confused about this, too. This is what finally cleared things up for me:

There is more detail about the boot process at droid-developers.org
[Milestone XT720 General] CrystalShield:
Now I understand what it is.

Thank you all you guys for your enthusiasms.

How can I change the standard stock Opera browser to another on the internet tab

Which browser is the best ?
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] conantroutman:
To be honest I never found a browser that could even compare to opera 9.7...

I guess its down to personal taste though.

As for setting it as default, I think it can be done via the registry but Im not sure how, sorry.
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Demon_man:
I always preferred opera 10 imo that ask you if you wanna set it as default when you install it, there is a tips & tricks thread here

http://xdaforums.com/showthread.php?t=583638

and im pretty sure there is another thread to it if you answer isnt in this thread mate
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] NTOP:
I use opera and think that is much better than IE.... :-)
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] D13H4RD:
Opera For Me like : )
[HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting] Dr.Move:
For me, it's between opera 9.7 and 10

I use 10 as default, but whenever I have a problem viewing a site I switch to 9.7

10 is more eyecandy and easier to use, at least for me.

you can always try java browsers, I've tested bolt and the old opera mini and they both work fine.
[Eee Pad Transformer General] grainysand:
So I was reading the Ars Technica review of the Tab 10.1 and found a lot comments were *****ing at how "hideous" and like "desktop Linux" Honeycomb is. And, eh, I don't get that. Honeycomb looks pretty good to me (I like blue and black, so sue me), and resembling a desktop environment is a plus, not a minus, the silly *****. What's supposed to be so hideous about Honeycomb as opposed to the blown-up phone OS on the iPad, the cartoonish horror of the Playbook, or another blown-up phone OS on the HP Touchpad?
[Eee Pad Transformer General] eli.kennedy:
I know what you mean. I find it really frustrating reading unbalanced reviews - and yeah, the comments section always turns into a kindergarten.

I expect a breakdown of functionality and usability. One person's hideous is another person's gorgeous - so I wish they would tone down some of the subjective style assessments.

Personal I find honeycomb to be acceptable. Give it a few months and people will be making it look awesome.
[Eee Pad Transformer General] HasC:
I too am no fanboy to any Operating system, well too be honest, I was a hardcore Winmo fan back in the days...

On a serious note though, I tend to go for systems that will do what I want and need from them and what they are capable of doing in the future... Before I make any decision to purchase this or any type of gadget, I do my research to see what the system has to offer hardware wise and OS wise.

For me Honeycomb at present fits the bill nicely due to its flexability, widgets and Androids general openness to be tweaked. Sure other OS's have their plus points but if they are going to highlight what they don't like about a particular OS or its hardware limitations or lack of expandability, they also need to highlight what their preferred OS cannot do against the one they are bad mouthing, this will be true and objective reviewing otherwise their reviews should be taken with a pinch of salt.

These reviewers also tend to forget that Honeycomb is still in its infancy and things should improve as we go along into the future.

Its pretty, I like it but everyone has different tastes :)

[Captivate Android Development] Haloruler64:
That's annoying, I've always adored the vibe and autorotate toggles. They were my FAVORITE. With volume rocker, it takes a long time and it beeps.

That's true. Still like it in the toggles. Considering airplane mode is in the power menu too, and I use the vibe switch ALL THE TIME and the airplane mode rarely.

Thanks though, guys.
[Captivate Android Development] designgears:
I can see the code in there for changing them, I will see what I can do...

Also, hold the volume rock down, it will go to silent without beeping.

OK just wanted to say Great job DG. Speaking of flashing, anyone else been so lucky to see the NEW AND IMPROVED PC/PHONE SCREEN. Yikes. It wasn't the 1click gingerbread that caused it for me but it was fun for a couple hours.

I was able to gget Odin 1click (original) to recognize my phone 1 time out of many tries and flashed back to that slow ass stock. Exited back out and again had a HARD TIME getting DGs Odin Gingerbread to see my phone. Hit start and it made it to the FIRST .bin file and stopped. I let it sit a while then the screen actually turned off. Pulled the cable and tried to start again but it was a No Go. Pulled battery and tried it again with my jig and only got the NEW pretty phone/PC screen. I found out I had 3 bad USB cables after trying it on a second PC. So off to the store and picked up a new USB cable and it worked PERFECTLY. Sweated it for a while but thought well that is why I use my second cappuccino for testing out roms. Hope you all do or maybe do not get to see the New pretty phone PC screen.

Thanks DG. Looking great so far, no issues restoring from tibia and no force closes at all yet. Look forward to your next version/s.

Also I have been on i9000 based roms and never realized that the call volumes were low. But made my first call with this captivate version and it is LOUD AND CLEAR. I guess I was missing the audience chip.

Coming from CM7, do you need to go back to stock 2.1? This seems like AiO package to me.
[Captivate Android Development] Copronymous:
No. 3G.
[Captivate Android Development] RockRatt:
Nope its not, only 3g. But I wonder why. I took the new modem and put it into a cm7 modem file and did have the H show up and download speeds of 2.5-2.7 and upload speeds of 500-1.0 which is about normal for modems on cm7 for my area in southern California.

[Captivate Android Development] littlewierdo:
Ok, just read thru all 20 pages of posts and did not see the one burning question I have answered regarding bootloaders.

I am concerned because one of my cappies cannot be one clicked to restore (it always soft bricks the phone and I end up having to do the 3 button recovery to restore to stock - and the 3 button recovery is what permabricks if the bootloaders arent correctly matched).

Does this contain the same bootloaders as Cognition/Cyanogen/Stock Froyo or are they different?

Go get Trillian, it supports google talk, all the IM standards, Facebook and Twitter.

I can't use Titanium Backup to restore my app. It says my phone isn't rooted and the app can't work. :-(

Update: I tried to root with I897UCKF1-AutoRoot-DesignGears.tar instead of the fugu method and it's rooted. Yay! Now on to flashing Cogn5b2, then b3. Whew! Thanks everyone. Sorry to be such a bother. I'm still fairly new at flashing. Cognition was the first ROM I tried (started with 3), and haven't done much else, so not much experience. Thanks for putting up with me. :-)
[Captivate Android Development] csdibiase@gmail.com:
Other builds of cognition enabled the H icon for hsdpa, current cog 5 betas do not. The default on an At&t rom is to us 3G for both a 3G and HSDPA connection.
[Captivate Android Development] singingmomof6:
Well, I rarely noticed what icon was on most of the time before anyway. However, I've noticed how much slower the connection has been since I upgraded to Gingerbread and Cogn5b3. The web pages take what seems like forever to load now compared to when I was on Cog 4.5.3, for example. I just don't know if this was the ROM itself, or my own mess up in flashing the ROM. Thus, the redoing of the flashing from a clean wipe and stock Eclair (and the ensuing problem with rooting, which, it turns out was my lack of knowledge of what exactly the fugu root method does, since the last time I rooted was with Cog kernel which did everything for me. Tee-hee).

Anyway, my phone is up and running again with Cogn5b3, and I'm in the process of restoring my apps with TB. Then I'll see how the network connection perform with this flash and let you know.

Thanks again, everybody!

I guess that 5 v1.0 is a non-wipe if you're coming from a DG version of 5 vbetax with GB bootloaders. I'd have to follow steps 1 to 3 if I'm coming from 4.5.3, don't have the GB bootloaders installed and still on CWM (Red) version 2.5.1.2.... right?

I could not find a list of known issues associated with the 5 releases in the OP. Is there a short list anywhere?... I understand that certain additional features, like Voodoo, will not be available until the developer gets a hold of the Kernel source. I'm just wondering about features that are native to the Captivate, like the video out as mentioned above .
[Captivate Android Development] RKight:
So is ext4 out of the question now? I noticed it wasn't in the changelog and there's no longer a list of planned features. :-\
[Captivate Android Development] msm903:
I think you would need Source code to implement EXt4 on a Captivated Kernel.

Unfortunately you're limited to Captivate modems.. So, if they don't perform well in your area you're pretty much SOL.. I think the choices are basically JH7, JI6, KB1, KE3, KF1... I know I9000 modems do work on this rom, but you get no voice, only data.

Anyways, here's a thread with a spreadsheet link that shows some testing done on KF1 with different captivate modems:

Make sure you are using the right button combo..

-Hold VOL UP + VOL DOWN

-Press and hold Power button

-Release Power Button as soon as you see the AT&T splash screen, keeping VOL UP + VOL DOWN pressed.
[Captivate Android Development] Uncle Irish:
Good info, thx

The speed is one of the main reasons I have to stay with i9000 based ROMs. Losing the extra is just too much of a hit for me.

You can always get the voodoo control paid version to have voodoo sound even without any kernal mods. UNLESS your talking about voodoo lagfix which I am guessing wasn't implemented due to NO source code for the kernal yet.
