Changing the Bootloader on XDA II? - MDA III, XDA III, PDA2k, 9090 ROM Development

Has anyone really tried to replace the original bootloader e.g. with one from familiar linux or redboot?
Though I didn't manage any of these loaders execute in RAM I found at least that BootBlaster 3900 from handhelds.org runs on the XDA. I only was not brave enough to click "Flash -> Program" :wink:
BTW: Is it true that Windows boots without a bootloader? I read it in one of the posts.
Thanks in advance

I think it is good you were not brave enough, cause it would have been stupid. Chance is very high you brick your XDA II forever. I have a half ported version of bootldr for XDA I, but haven't even flashed that into it. Never assume that something that works on one pocket pc will work on another. Especially at this low level.
BTW: Is it true that Windows boots without a bootloader? I read it in one of the posts.

It was certainly not on the XDA I. There has been talk that it was the case for iPaqs. I have no idea about the XDA II, but I'm not prepared to test it to find out .

Well, if there is no replacement bootloader at hand, how far could we get using the original bootloader. I would like to boot some linux kernel at least to see what is working and what not.
As far as I can see the l command should do the job. My main questions are:
0. Can I (accidentally) load anything to ROM with l (and thus screw up windows)?
1. Can the bootloader be used to pull an initrd and a linux kernel over USB-Serial to RAM and run it from there?
1.a) How do I address RAM?
2. Does the kernel have to be preprocessed / formatted in any way?
3. How do I actually setup the connection for l to load something from my linux box?
Thanks in advance, I'm looking forward to your replies.

[APP] Milestone - Overclock (requires root)

Hi all,
I realize this is a post about a Motorola phone but please bear with me.
As you might know, the Milestone firmware is firmly locked, unlike its cousin Droid. Among many things, this forbids overclocking because we can't change the kernel and unlock new frequencies.
However I developed a solution that allows overclocking by changing key structures directly in the kernel memory in runtime. All you need is a rooted phone; no flashing involved. For this to work, the module must know two memory addresses that are specific to each kernel. Fortunately, Motorola appears to have reused its kernel on most 2.1 firmwares, and I've yet to come across a firmware where it doesn't work by default. Confirmed working are Central Europe, Telus and Brazilian firmwares. Testers are welcome to give it a try.
Now for the relevant part for XDA: in theory this can be applied to any kernel on any other phone. You may say it's unneeded because you can already overclock; but you must flash a specific kernel to get a particular speed. It would be much better to be able to set any maximum frequency/voltage on the fly without flashing or rebooting. For instance, you could overclock to 1.0 GHz before a browsing or gaming session and then return to a lower frequency like 600 MHz, though still overcloked, for battery savings and safety. It's up to you.
Milestone users can try it out now:
http://code.google.com/p/milestone-overclock/
For the rest of you, what do you think?
sounds fantastic, I'd love to check it out but for the life of me I can't find the page.
If you want to pm it to me, I'll post it.
Nice. Telus Milestone User here. Would love to learn how to do this for mine.
Here is the project link:
http://code.google.com/p/milestone-overclock/
found it. looks like a fantastic idea.
How can we help get the addresses?
awesome .....wht there is no milestone/droid section here is beyond me ....wtf
Because it was decreed months ago by someone and no one seems to like changing their mind once they make a decision in this day and age.....
but it's need to root, could you fix it?

what's the problem with rooting the milestone? There's plenty of solutions for that. Just no custom kernel/ramdisk, which this works around by using a kernel module.
hi,
i use the 2.1-reu version on my milestone,
but in order to prevent the 2.1 introduced alarm bug,
i have updated the kernel (only) to the 2.1-telus
(via a sbf).
is possible to use this mod to overlock my phone?
how?
if not, how help you to obtain the addresses?
thank's and continue your great work!

XDA is a HTC developer forum, not an Android forum. Google some moto modding sites, i know modmymoto.com is pretty good, found out how to root the Cliq (garbage) there.

Will the method to find the right address that will be posted at /wiki/Disassembly work with every phone and kernel,too?
Has the app something like a setting where you can just change the address to the one you found with the method above?
Would really love an overclocked 2.1 on the HTC HERO. There is no oc-2.1-kernel for the Hero, yet.
Thanks for the great work, til now!
this is a good via to mod any application.
please, publish the source code of your applicacion ASAP.

Source code for the kernel module released
Hi all,
Thank you for your support. I've just uploaded the source code for the kernel module and also the standalone module itself (it's included in the apk but still). Will write the Disassembly section soon, stay tuned.

hi,
i'm interested on include this in my system applications directory,
in order to prevent your deletion on hardreset, and in order to make it available FOREVER
the instructions are that:
cp OverClock.apk /system/app
cp OverClock.ko /system/lib
????
thx
The overclock.ko is created automatically when you press the "Load module" button in /data/data/pt.com.darksun.milestoneoverclock/files/overclock.ko. You don't need to copy it. I'm providing it separately so that people can load/bundle it without ever running the apk.

ok,
if i'm interested on have overclocking on my milestone after boot the system, and don't interested on manually execute the apk on each reboot, i need only to copy the OverClock.ko to /data/data/pt.com.darksun.milestoneoverclock/files/overclock.ko on boot time ?
but in your wiki page says to execute "insmod overclock.ko max_rate=800000 max_vsel=62"
please, provide me instructions to set overclock in boot time
The module created by the apk is preserved across reboots. However, if you want to run the module completely standalone I recommend you put it in /data/local/overclock.ko and run insmod /data/local/overclock.ko max_rate=800000 max_vsel=62

Need some help with an Andoird build for my dad.

Hi
First off all I want to say: I can probably find everything here in the forum but I'll spend hours and hours reading and most off the time I'll read useless info that I don't need so if you have the knowledge and it just takes 5 minutes to share it please help me out I'll be thankful.
I myself have a HTC legend and have read LOTS off posts before finally rooting and flashing custom roms. Now my dad has asked me if I could help him to get android on his HD2.
He needs to be able to sync his agenda with outlook (for work (Calendar and contacts) I read something about HTC sync should be working on newer kernels is it included in some builds then?), and have a stable build (its not a ROM if I'm correct?) one that he could use for daily use. Don't need anything too special (not even root but its not a problem if it does have root access)
So I've started reading around in the development section and from what I read I don't need to root or flash anything, just extract a zip to the SD and name it Android. Is that correct? (then why do you have special android roms?)
So is there someone who can link me to a good stable (no OC kernels and stuff please) Android Build and tell me if there are known bugs with HD2 builds that don't get mentioned in those threats because they are known as general knowledge.
Thanks in advance
If I could ever help you back with HTC legend problem or something I'll gladly do it for you.
grts
Jonas (sorry for the pour English it's not my main language)
I'm reading topics and If I find answers I'll update this but please if you have the knowledge to help me in a few minutes PLEASE do so.
Never mind found this post: http://forum.xda-developers.com/showthread.php?t=782930
and solved most of my questions looks like its not as fully operating as I thought :s.
So It's not just as easy as unzipping and renaming that would have been too easy.
It isn't very complicated to run android on the HD2. I don't know what feature you suspect isn't working that scared you from attempting. Every feature I could want is working. You also don't need to sacrifice windows mobile if you try android. Give it a shot and post again if you have trouble.
Problem is that I need to root and flash other wm Rom if I want everything to work as it should. Or isn't that really necessary? I'll just try a build and see what it does. Thx for th reply

if you have to hspl your hd2 depends on your stock radio rom version. it should be a newer one like 2.10 or 2.12 to avoid most issues with android. flashing another winmo rom is only necessary if you have robot voice and/or faster playback of music (just to mention 2 problems)... you don't have anything to loose if you try android from stock hd2. if it's not working fine, you may think of flashing a new radio and/or rom!
So if I unzip the file I can dowload here put it into android folder in the root of my SD, I'm good to go? What about that kernel do I need to flash it??
if he uses it for work then i'd suggest laying off android for now
he could still use the WM? It's just like a program no? So by just removing the folder it would be back to normal?

You basically reboot the phone and it goes back to wmo. Its almost like running a live linux cd...
When you run HaRet Android takes over the phone. When you reboot it will come back to WinMo. Then you run HaRet again and you back in Android. And so on. WinMo 'lives' on the phone, Android on sd.
So the kernel they are talking about is a fake kernel? (not flashed to the actual ROM)
So if anything goes wrong at first boot with the android I can just pull out the battery without bricking the phone?

Its not a fake kernel...it is real but it resides on the sd card so your original wmo stuff will still be there in case you ever need to use wmo again.

You s should start your own thread. There are many different unlock so specify which one you're after, sim unlock? This section is only for android so if you need help on something else, post it in the hd2 general section, not here. Unless it is android related, you won't find help here.
Ok so if I install this:

You are correct.
If it doesnt work for you just erase the android folder. I would recommend flashing hard spl, and changing your radio to 2.12.50.02_2. Then load the hyperdroid 1.6 rom. You will have the best luck with that probably without having to change anything in winmo.

I'd recommend using a spare SD card. When you run Android it creates a ton of folders on it, so it's easier to have a dedicated one than to try and delete everything later (if he decides not to stick with Android).
Also, I read through the thread and couldn't see anywhere... did you tell us what radio is on the HD2? It needs to be (I believe) 2.08 or higher, and it's VERY recommended to have a 2.x.50 and not a 2.x.51 radio.
If you flash a 2.x.51 radio on a t-mobile US HD2 you will brick it. Try flashing radio 2.12.50.02_2

Yeah dno the radio version or the bootloader version.
Do i need root to see that?? Is it just booting while pressing volume down to get the bootloader and the info I need?
Also I read that the HyperDroidV1.6 is overclocked and undervolted and I drather not do that. Just want it as stable as can be. (I know my overclocked legend is stable but if he has a really crappy processor,..)
BTW: I know what overclocking does but what's good about undervolting?? better batterylife?
I think I'll just give this a try this weekend (when my dad (and his phone xD)are home)

I'm assuming undervolting is for better battery life, but have never bothered with it myself. Just have a read of the most popular Android builds to see which you think will work for you. I can recommend FroyoStone Sense v3.1, but I would because that's what I use!
It's so easy to try the different builds that it's no big deal if you play with one and don't like it, so don't be shy - give em all a go if that's what it takes!

Xubuntop - A full XFCE4 desktop

The stock Webtop sucks in my opinion. A outstanding concept, but poorly executed.
I'm working right now in a "revamped version" of the stock one. I call it Xubuntop - A full XFCE4 desktop.
Xubuntu is originally a Ubuntu with XFCE4 environment and some optimizations. Check the original Xubuntu project (Google it)
I'm thinking in two versions: Lightweight and Full
Lightweight: flashed in Osh and ready to go!
Full: flashed in Osh and uses Webtop2sd to expand the internal disk space.
I know that many tried to do this and I warn you guys, I'm not rediscovering the wheel. It's just a "easy way" to get those extra applications using the Xubuntu as a base.
It will feature optimizations to make the environment as lightweight as possible, giving the CPU more room to process whatever you want to execute.
I'm working two weeks on this and maybe this will be ready Saturday, but I can't promise nothing
Maybe I'll need help to make the zip to use in CWM.
So... let's go back to work
I have a questions.
Is Xubuntop for cm7/9 roms or blur/stock roms ?
Will it be dependent on the broken/outdated Motorola packages?
By this I mean, will we be able to make full use of the repos to install newer versions of software that are dependent on newer versions these packages. (E.g. the latest verision of Chromium that I can get working now is version 4 due to its dependencies breaking webtop, even when apt-get has been fixed.)

Xubuntop should work fine with the Blur and Stock roms.
CM7/9 boots the Webtop from the Webtop2sd? If yes, then I guess the "full" version can work.

In some parts, yes, it will be dependant.
My intention is to hold the core packages and add the lastest (and functional) repository with Arm support, 10.10 I guess.
The other alternative is get the source code and rebuild them in Arm architeture. This demmands a lot of work and I can't do it all by myself. But with more time and people, it can be done.
If it will run the latest available version of Chromium from the repositories (It was version 14 last time I checked) that's all I'm really concerned about. Good luck!
I guess it's impossible to squeeze a light version to fit inside the 0.8gb osh reserved space. Crap!
By the way, the system is more fluid than before. I'm trying to remove all non-essential packages right now.
With AT&T stock kernel (1Ghz) GtkPerf test run now in 13s. A huge difference.
Please give WebTop2SD a try to have a much bigger osh partition .

Edit:
I'm having a hard time trying to port the lastest Chromium-browser. I need to re-install ArchLinux in my desktop first and see if I can make it work there. I'll delay Xubuntop a bit trying to port it.
I did installed xfce4 after using webtop2sd. But i ended up with a lot of stuff laying around not used, i'd like some more integrated!

Do you have experience in cross compiling? I'm stucked on this...
Would this run any faster than the current webtop with xfce4 interface? My webtop functions, buts slow as hell off my sd card sometimes. Its a class 10 pny card.
Only on windows (we use windows CE and its variants at work) but let me know how we can work.

I'm working very hard to port the Chromium-browser 18.0.1025 (latest official), I've just bricked the webtop attempting to upgrade some core files... Not a problem... I was expecting this.
I'll not give up.
I broke my webtop so many times trying to get newer software to work that I just made a disk dump of a working partition that was configured how I want it. If I ever have problems, I just restore the disk dump, and within a few minutes I have everything working again.
this has me VERY excited, but XFCE still isn't lightweight enough IMHO.
What are your thoughts about Fluxbox? I remember having DamnSmallLinux on a 200mhz machine with 128MB of RAM, that was very responsive...
That said, we don't have a webtop subforum.
Which we really need, to collaborate efficiently.
Any ideas? This forum is way to frickin busy.

[RK3188/3066/2918] Custom Firmware Tool for Windows

Longtime lurker. But its time to contribute! I recently bought a TimingPower RK3188 and searched high and low for these tools. After endless hours of searching and translating Chinese and Japanese I brought this little package together to build your own CFW. This probably isn't for complete newbies but I made it as simple as possible. I can confirm it works on my TimingPower RK3188 using Rockchip Batch Tool as well as copying update.img to SD. Anyway, enjoy!
This is what it does:
Extract update.img as well as system.img
Pre-root your firmware
Open system folder to edit your rom
Repack update.img
I cant post links so previews are a no no I guess. Let me know how it works. If this is the wrong section I apologize.
Thanks !!

I am quite happy with them. However, some notes are in order. I received them with firmware 20130715 installed, and that does not support 1080p. The timingpower.com website offers 2 updated images for it, one 20131101, the other 20131104. The 20131101 image has some improvements over the 20130715 version, but still offers only 720p, but the 20131104 version does offer 1080p. I updated both units to the 1104 version, and it went smoothly, but it can be a bit unstable at times. The screen and sound cut out at random intervals, but I got used to that, even thought it is quite annoying. Overall the picture is amazing (i use it on a 65" flat screen). Speed is acceptable, not a gaming computer, but fast enough. Takes a bit to get used to using it, keep wanting to right-click stuff for options, and get dumped back a screen.
Suggest that you get a USB 2 hub (more ports are better). I connected a USB keyboard, USB mouse and USB camera (all cheap, nothing fancy), and they all worked fine. However, the tiny Bluetooth keyboard (IS11-BT05) that I got, doesn't seem to work. It pairs up just fine, and shows as recognized, but after that, nothing.
One caution note: if you do flash your device, make sure that you use a newer computer, with USB 2.0 , really old PC's with USB 1.1 will not work.
Making your own version of the ROM shouldn't be too difficult. Plenty of advise here, and there are even some tools available on the TimingPower site. I'm in the middle of customizing mine, and I have not found it particularly difficult. I mainly want to scrap some of the basic stuff, and make it more sleek (to my tastes). I am also considering incorporating a dual-boot option, for Android <-> Linus (not sure of what flavor yet).
BTW, I have an English translated version of the Chinese RKBatchTool Manual, should anyone need it.
thanks!

I'm pretty new to this. I just rooted my phone, but don't know much on about it.
I hear people talk about downloading kernels and ROM, but in clear words, what are that?
I tried Google it, but not quite sure. Kernels is overclocking or underclocking your phone or something like that?
But what is ROMs then? A new "system" on the phone or something like that?
Thanks in advance.

How wrong can i go?
Not doing anything I have no idea about tho. I just rooted with CF-Autoroot, which shouldn't cause problems and now I just want to search more info.

Are you familiar with the Windows PC terms? If so, I will show you a quick comparison for easy understand
- ROM (or firmware): contains the OS (Operating System), i.e Android.
- Kernels: a driver. A software (OS) talks to the hardware via the kernel.
And also some more terms:
- Bootloader: same as BIOS (CMOS) in the Windows PC.

Just FYI, you can obtain the detailed version information about Bootloader, Baseband, PDA, CSC... by using Phone INFO ★Samsung★ app.
(in the FIRMWARE INFO section).
