I have flashed Haykuro new spl and his 6.0 build.
I was lucky i had the old phone and the new radio
and now we know that we can not reflash old radios with out risking bricking our phones.
I did not know that the radio had any thing to do with the spl.
(may be memory size and location)
My questions about the spl are this.
Was there a over site made / bugs with the old/new spls and radios?
When new radios come out, will we be risking bricking our phones by flashing them with this new spl installed?
With out Haykuro spl will we be increacing the chance of bricking our phones if we install new radios?
will the new spl be needed for all of Haykuro's new builds?
I have a fresh out of the box phone and the spl worked
I would like to know too! however it's difficult to say, we'll have to wait and see what happen when HTC roll out new radio in the future.
maybe haykuro can shed some light on this...
Please search and use already open threads before making a new thread.
will any of this work with the myTouch? im in the US and have one, but havend done anything to it yet. I have a rooted G1, would i be able to use the same JF software? if these are all dumb questions, dont tell me. lol
I was just going to post about this. I cannot seem to get any of the rooting methods to work with this phone. Here is the info:
SAPPHIRE PVT 32B SHIP S-ON G
HBOOT-1.33.0006 (SAPP30000)
CPLD-10
RADIO-2.22.19.261
May 27 2009, 19:06:41
Any help would be appreciated.
You can't root the MyTouch 3G due to what haykuro described as a "perfect" SPL.
That's true. Haykuro is saying that it is the perfected SPL on his blog. Don't fret everyone as this just makes dedicated hackers like Haykuro more interested in being the ones to root it.
Go Haykuro Go!!!! I know you've put in hours upon hours of hard work rooting our beloved devices and moving us forward in the field.
Thanks.
That doesn't mean I forgot others who have put hard work in. I just wanted to let Haykuro know as he has been missing from our scene because of the poor treatment or lack of credit when due.
I'm not sure you comprehend what the SPL is since its not as clear for Android as it is for WinMo. The SPL allows you to overwrite the entire system and the modified SPL's allow you to flash unsigned. Now the SPL resides in a part of the device that stores other vital low level software like the radio and such.
In order to flash the SPL, the new SPL has to take the same exact place as the old one using the same exact memory addresses or else it will overwrite the other vital low level like the radio and one incorrect byte in the wrong place could cause you to be unable to make calls, etc.
This is where it gets to be a pain in the ass because the SPL is what allows you to write to low level parts of the phone and more importanly use the USB port as a serial port. If the SPL is flashed badly and you can't communicate via USB anymore you now have brick unless you know JTAG. Another problem is if the radio or anything else overwrites part of the SPL causing a brick.
In other words you will probably be able to achieve root via a software exploit but if the SPL cannot be replaced then you will never be able to flash a new ROM.
Hope that helps. sry for being so long winded
how about after achieving root (via software exploit), we replace the recovery.img with a modified one via adb shell? Is that possible?
(n00b here)
The SPL will not allow it to be written although there may be a solution like fakesigning ROMs using some sort of security hole.
like previously mentioned the SPL will not allow it. So until a great mind like Haykuro finds away of replacing the SPL with a modified one not in an update.zip or a fastboot flash it will not be posible till then. Maybe a nbh file might be possible but currently there is not one that is available for this device yet.
nope cuz .nbh = updates.zip for winmo and works almost the same way
mytouch
rogers started a fund raiser i think we need to start another one?
Has anyone tried using a Goldcard to flash Dreaimg.nbh or another system image? It's been done on the Dream, I don't see why it would be any different on the MyTouch.
Someone needs to figure this out. This is the only thing keeping me from buying a MyTouch. Someone help free me from my loose hinges and inexcusable lack of system memory on my dream...
So, I just compiled my first test ROM. One big question, can a bad ROM brick my device?
I wouldn't think so, since I have the SPL unlocked by Hard-SPL.
But clarification would be good -- and I can go ahead and click Next.
Just do it. When you have hard spl, it's really hard to brick your phone. There was a dude in the raphael forum who was trying to brick his phone by pulling the battery mid-flash and other similar things, and he couldn't do it. The only way to fully brick it is to kill the bootloader somehow, like by flashing the wrong hard spl or by flashing a radio from a newer device that isn't compatible with your device (must be security unlocked to do it). In my experience, it's pretty darn rare to see someone post about bricking their phone permanently without doing something obviously wrong.
Now, it's possible that you'll cook up a rom that doesn't boot, but you can pretty much always flash a working rom that will boot up fine afterwards.
Yeah, exactly what I thought, Off we go.
Thanks
Hello I just bought a mytouch 3g Ive been doing some research on rooting and all that stuff. I have since flashed the latest Cyanogen ROM, however I am looking to flash a Hero ROM with the sense UI.
It seems to install the ROM image onto the device I need a certain SPL. I checked my SPL and it is one of the "perfect" SPLs.
My question is how come I could root the mytouch and flash cyanogen without changing my SPL, but to install the hero rom I am required to?
Also, how safe Is flashing the SPL, which one should I use, and whats the safest way to go about flashing it?
search in the dream section on how to flash a spl. to run a hero rom, you need haykuros spl, which is 1.33.2005 (i am pretty sure lol)
however, flashing this spl COULD BRICK YOUR PHONE. its not a 100% brick rate, but i know that people have bricked while doing it. so READ ALOT BEFORE YOU DO IT, OTHERWISE YOU WILL BRICK SOMEHOW. SO READ AND SEARCH AND READ SOME MORE.

PLEASE READ THIS THREAD FOR UP TO DATE INFORMATION : http://forum.xda-developers.com/showthread.php?t=655097
***O.P. EDIT***
The link above does contain some more detailed information but the guide below has yet to cause a brick.
IF YOU PLAN TO FLASH THIS SPL PLEASE READ THIS WHOLE POST
This is for the Dream/G1 ONLY. If you have a Sapphire/MT3G this SPL is not needed.
If you have no idea what a SPL is or you are looking for info on other SPLs please read this page http://code.google.com/p/android-roms/wiki/SPL
Let me start off by saying that I have nothing to do with the actual development of the SPL. I also take no responsibility if you do decide to flash this SPL and brick your phone. That being said I decided to create a "How To" for the SPL for the simple fact that I would have switched to it long ago if I knew how easy and safe it was.
The SPL that you need for many of the new Eclair ROMs along with Hero ROMs and some Donut ROMs like Super D is a special SPL created by Haykuro that basically gives you more space to flash larger ROMs. When Haykuro first released the SPL there were reports of people bricking their phones. It turned out that the reason for the SPL causing a brick was because the SPL needed to be flashed over the latest radio and requires a PVT board. If the SPL is flashed over a radio version prior to "2.22.19.26I" or on a DVT board it will cause a brick. After people heard about this SPL causing bricks it became known as the Danger or Death SPL because of the danger that it can cause death to a G1.
A lot of people including my self were very worried about flashing the SPL in fear of a bricked phone. The result being many people not wanting to flash certain ROMs because they do not want to brick their phone. Some devs have actually changed their ROMs just to make them small enough to flash with out the Danger SPL so that more people will use their ROM.
Well if you are reading this and you don't have the Danger SPL because of the fear of a brick well then don't worry its ok to be scared but this "How To" will get you through it safe and sound.
IMPORTANT: Before going any further make sure that you have PVT board. You can do this by rebooting your phone and holding the camera button. The first line should say "PVT" if you see "DVT" then DO NOT flash this because odds are you will get a brick but If it says "PVT" then you are good to go.
First you are going to need to download the latest radio and the SPL. both can be found here http://code.google.com/p/sapphire-port-dream/ There is also a new radio that is compatible that can be found here http://forum.xda-developers.com/showthread.php?t=640535
Prior to starting the installation process please make sure that your battery has a good charge. Also DO NOT pull your battery out at anytime during the installation process. I know it seems like common sense but I read a thread where someone had pulled their battery in the middle of the installation process and they ended up with a brick.
Now that all that's out of the way lets get started!
1. Copy "ota-radio-2_22_19_26I.zip" or "G1-radio-2_22_23_02.zip" and "spl-signed.zip" onto the root of your SD card.
2. Reboot into recovery. I suggest using the RA-dream recovery you can download it here http://forum.xda-developers.com/showthread.php?t=566669
3. Wipe your phone "factory data reset" (this step isnt really necessary since your phone is wiped after flashing the SPL but I always like to wipe before flashing anything)
DO NOT SKIP THIS NEXT STEP OR YOU WILL BRICK YOUR PHONE
You must have the latest radio "2_22_19_26I" or "2_22_23_02" to flash this SPL if you already have the latest radio you should not have to flash it again but it will not hurt if you do flash it again. When in doubt flash it anyway.
4. Flash the Radio "ota-radio-2_22_19_26I.zip" or "G1-radio-2_22_23_02.zip" it will install and then it will ask you to reboot to finish the installation, so reboot, it will then finish installing and then reboot back into recovery.
5. Flash the SPL "spl-signed.zip" it will install and then ask you to reboot to finish the installation, so reboot, it will then finish installing and reboot into recovery so you can flash your ROM
A simple way to make sure that the SPL flashed correctly is when you reboot to the boot loader screen by holding the camera button you will see HBOOT-1.33.2005. You can also see that it flashed correctly by checking your system size it will now be 89mb a very easy was to check this is with the My Account app available in the Market.
Great idea to post this again, since so many people are asking about it.
I flashed mine way back when Haykuro first posted it, and I seem to remember that you had to have a PVT board as well. Is this still the case? I can't remember whether or not anyone found out otherwise.

PVT = a must have.
Also forgot to mention that when you reboot after flashing the SPL, you have to reboot with Home+Back

Yeah thats a big reason I decided to post this, so many ROMs now say they require Death/Danger SPL and only a couple actually provide a link or some type of simple instructions. I figure with a dedicated "How To" we can eliminate questions about the SPL in ROM threads and make people feel a little more comfortable with flashing it. I dont believe anyone actually tested it without a PVT board. I havent even seen anyone one here that doesnt have PVT board. Just in case though I will edit the OP, thanks for remembering that because I completely forgot that it has only been tested on a PVT board as far as I know.
also you should include how to know which spl you have. i was about to flash the danger spl again because i forgot i already had it

If I remember right, some people flashed the radio first, and still bricked, and the difference was that they didn't have a PVT board.
Maybe you should also put in big red letters at the beginning about flashing the radio first. You can tell by reading all the questions on here that at least half of the people don't read the instructions, they just flash away in any order they feel like flashing!

Very true red letter warning has been added.
Please if anyone has suggestions for this "How To". Dont hesitate to post. I made this to help people out so if you have an idea that will help let me know.
When I first got a G1 as a test phone I tried to flash the radio/spl and it failed repeatedly. I'll try it again as I have had the phone for awhile and I want to try some of the newer ROMs
EDIT: Still getting fails on the radio flash.
it says:
Install from sdcard
Finding update package
Opening update package
E: Can't open /sdcard/ota-radio-2_22_19_26I.zip (bad)
Installation aborted
could it be my sd card?
It looks good now!
I remembered right:
Ok if u press the camera button + power to power the phone up and if u see "PVT" then ur good to go if u see "DVT-1 or 2" then u should defenetly not flash cuz almost every1 with dvt gets "bricked".

it is called Haykuro SP: .2005 you guys have to get your facts straight.Haykuro is the person that ported the Magic's SPL to the Dream to allow larger roms to be installed.
Both the Radio & SPL are here:
http://code.google.com/p/sapphire-port-dream/
So does SPL flashing only apply to G1's? I have a mt3g. I can safely flash any rom w/o flashing an SPL first?

Thank for finding that I just edited it again
I'm snowed in tonight, so I'm gonna try this out. I hope everything I need to know is here. If I do a Nandroid+EXT backup before, will I be able to Nandroid Restore after the SPL upgrade?
So I tried to flash the spl yesterday cuz i wanted to try out some new roms, but I kept on getting errors everytime I flashed the spl and it aborted. So after a while i just gave up and went back to cyanogen. Does anybody know why there would be errors when installing the spl. and yes I did flash the radio first.

That is correct. This SPL actually is the one that if for your mt3g but edited for the G1 so that it can flash larger ROMs.

Its called Sapphire to dream port for a reason.You can use the .2004 or .2010 SPL or whatever its called instead.
If I already have the correct radio, do I have to re-flash the radio again before flashing the SPL?
The reason I am asking is that I have 2 G1's.. the first I unknowingly did everything right and have the danger SPL without any problems. When I went to root the second one a couple of months later, I bricked it even though I thought I did everything right. Now my "new" phone has the correct radio, but only the engineer's SPL and I want to try some of the newer ROMs but am afraid to brick the phone again.
Thanks
