how do you find out what spl you have ?
can someone breifly explain to me what SPL is
and i right in thinking SPL is what can make a brick ?
hold camera and power to boot in to the SPL (when the phone is off) and it will tell you. A rainbow screen means it's stock.
The SPLs other than stock allow you to use fastboot to flash things like splash images and restore nandroid backups. Haykuro's SPL (aka "Danger SPL") allows you to run HTC based ROMs like Hero and Rogers. Make sure you have the cupcake/1.5 radio (which you should already have) before flashing, otherwise it will brick.
Downgrade to Hard SPL from Danger SPL??

When I rooted my phone I installed Haykuro's danger spl with the latest radio. I didn't know it can potentially brick your phone (hence the danger part lol). I'm running cyanogen 4.0.1 and it's working just fine so far but I had 3 questions
1) Is Hykuro's Danger SPL only risky during the installation process or can it still possibly brick your phone after a successful installation (in other words, elaborate on the "danger" part please)
2) Can I downgrade to Hard SPL after installing the Danger SPL
3) How would I downgrade to Hard SPL?
Thanks guys!!!
If you are using Haykuro's spl there is no need to downgrade, it will allow you to run anything the hard spl will and more. The only "danger" with haykuros spl is when you flash it, if you successfully flashed it then you have nothing to worry about.
Rodey is correct, that H's SPL does everything hardSPL does (fastboot ect) and sloows you to run HTC Based ROMs. I don't know why you would want to downgrade but if you do it should be as simple as flashing the hardSPL update.zip. Get a secind opinion on that though if you want to try it, I'm no hardSPL expert.
You will only brick your phone with haykuro's SPL if you dont have a PVT board (camer+power to boot in to SPL, it will tell you) and if you dont have to 1.5 radio. To check either in the SPL or Settings > about phone check the baseband is version 2.22.19.26 (if you go to about phone there will be some crap before the number, ignore it).
IMO H's SPL is just handy to have. As long as you have the new radio and a PVT board nothing *touch wood* should go wrong.
One more thing, when flashing the SPL, don't play hot potato with your phone ;-)

Thank you guys! In that case I'll just keep H's SPL seeing that I already installed it successfully without bricking my phone (yay)
Really appreciate both of your time!

Unless you are Unrooting and flash the original spl. I've done this many times so I know it works.
Does SPL: 1.33.2005 help the regular ROMS run better (Cyanogen's)?
I use dxTop, seems to run out of memory quickly.

If you didn't downgrade to RC29/7 then you should have the 1.5 radio. Check by going to Settings > About Phone and baseband version. It should be 2.22.19.26I.
I think you can just flash HardSPL as update.zip as you are, but I' not completely sure...

I swear I've heard people say they have, but dowgrading the radio after installing Danger SPL did cause bricks...
I'll go check
You WILL brick your phone if you attempt to downgrade your radio after flashing the new SPL or if you do not have the latest radio installed before flashing the new SPL

@Adrian K and nephron
When I unrooted my spare G1, I got it completely back to stock (circa October original shipment stock)
I downgraded my SPL successfully from the danger SPL all the way back to the original SPL. Also when I downgraded back DREAIMG.nbh, I confirmed at the time that the radio downgraded with it. My original post was on the unlockr.com when I was trying to help David of unlockr.com with some tutorials.
My original quote from unlockr
BTW: I have confirmed via the bootloader that the radio DOWNGRADES back to stock by applying the DREAIMG.nbh update FYI
From the bootloader I am now at
DREA100 PVT 32B
HBOOT-0.95.0000

I think it's downgrading the Radio, while on Danger SPL that will brick your phone b.
I have also gone from Hard to Danger back to Hard again with no issues.
if i use the 1click root method and then install cyanogens 4.0.1... do i actually need to do the hardspl and the radio or is that all taken care of? that's the only thing that's confusing me a little bit...

If you are talking about the one click method that is know on the market as recovery flasher, that only takes care of granting root access and flashing cyanogen's recovery image. The radio and spl upgrades are on you.
Try here for more explanation
http://forum.xda-developers.com/showthread.php?t=550050
yea that's what i'm talking about... now don't get me wrong, i believe you guys here on xda first and foremost... but theres a video tutorial on android and me, and it doesn't show them installing the radio and spl between using the recovery flasher and then installing cyanogens 4.0.1... are they not doing it right in the video or are the radio and spl optional? all the guides on here seem to say you do have to flash them but the video clearly shows them not stopping to do it. so maybe their video just sucks haha. but any idea on that?
thanks so much
I have 1 click rooted and installed Cyanogen 4.01, I am on CRC1, my understanding was as I was already on 1.5 Cupcake, my current SPL and Radio were current.
I read somewhere that the 1 click method is only temporary root. But if someone could elaborate on this it would be very helpful. Also what is this hard spl ?
Hi,
I seem to have some issues delievering SMS under the new radio (I assume it to be the cause).
I'm currently using both SPL and Radio from Haykuro (that I flashed in order to try on Hero roms), but, having the above in account, I'd like to return to stock radio (version 1.smth).
So, taking teh brick factor into account I was considering doing the following:
1) Flash DangerSPL
2) Flash Stock Radio
Is the procedure safe/correct/in correct order?
Where can I get the stock radio?
DO NOT flash the danger spl and downgrade radio, youll brick for sure. Id just try a reflash of the radio, rom or both first.
Download the older radios at getyourdroidon.com
Ok, so my phone's currently on eBay. I'm leaving the android world and heading back to iPhone land. So I'm going to need to unroot.
My specs:UK phone, 26I radio, 1.33.2005 SPL, Cyanogen 4.04 + 1.4 recovery.
So do I simply flash the RC7 update to get back to 1.0 (it's a UK phone, so not 29) via the SPL (which isn't stock)? As far as I'm aware the recovery image on stock G1's allows the user to flash official updates, so can I just flash the one for 1.5 or 1.6? Does anyone who where I'd find those offcial updates for UK phones?
you want to flash the original SPL first, then you can load up your RC7 and that will overwrite everything else
**edit** I know the official OTA UK cupcake update was posted to Phandroid around May, cause I used the UK version to check out cupcake before it was available in the US
I thought the RC7 NBH would also flash the SPL...at least that's what I read. I guess I can always reflash the stock SPL, I'm just trying to be uber cuatious and not brick this thing...
no the nbh file will overwrite everything excepts your spl, you have to flash the spl first then boot your phone using camera + power to acess it to flash your nbh file, then you'll have RC7, then your phone is back to stock, then you can search out your official updates like rc9 and higher if you choose or sell it with rc7 and let the buyer wait for OTA updates
Ugh, you're right it even says it in the root guide. Thanks!
Now all I need to do is find the uk update.zip for 1.5...
this link still seems to be valid for the UK cupcake update

I was also under the impression that the nbh replaced the SPL as well. I have read many posts in which users stated that they safely downgraded to RC29/RC7with the DangerSPL and didn't brick. Also, the .nbh flash also states its replacing the SPL during the flash IIRC. Anyways, better safe than sorry.
Don't you think that you would get more money for selling a rooted G1 over stock? AND WHY IPHONE :'(
AdrianK shall be missed
I have the latest cyanogen rom and i know it flashed a new radio when i did that (via the htc update)
now if i wanted to swtich to a new rom like MLIGN hero 2.8 would i need to flash back to the older radio(radio 2.22.19.26I)?
im just trying to avoid a brick, i've already bricked one of my phones switching radios lol

Pretty sure 2.22.19.26I is the latest radio.
2.22.19.26I is the latest radio and has been since cupcake.
Boot into hboot [camera]+[power] and it'll tell you what version you're using. I will bet my own anus it's 2.22.19.26I.
yea it is... i was pretty sure in order to get cyanogen's rom it changed your radio image when you flashed the htc recovery image, im guessing it was the same one i already had then

Yea the HTC recovery image does include a radio, but its the same one we've been using for ages.
Incidentally, it's not radio images that brick your phone, its the 1.33.2005 spl (also known as Haykuro's spl, deathspl, etc), which is only compatible with radio 2.22.19.26I, so unless you're using that spl you can flash radios freely.
lol i wouldnt say freely.... radios can cause bricks just like spls lol
After trying some custom roms I decided to flash back to stock one from Era GSM (network provider that branded and released the fw). However, I got stuck on T-Mobile G1 logo. The firmware was in flashable zip.
On Polish android forums I was told that I have wrong radio and spl and that another thing that may interfere is custom-MTD recovery. SPL is 1.33.0013d, radio is 2.22.27.08.
How do I flash correct SPL, radio and recovery without bricking the phone?
Or maybe there somewhere is Polish locale for DreamTeam froyo or Froyo Melt? Then the problem won't exist
If you didn't already bricked your G1 (sound like you did if you can't get into the fastboot)
Follow the instruction from ezTerry, link below:
http://forum.xda-developers.com/showthread.php?t=831139&highlight=2708
Recovery works. I don't know about fastboot.
I already have the radio and hboot mentioned in thread you linked to. So basically the only thing that I have wrong is MTD-recovery. Does flashing only Amon_Ra recovery will make android 1.6 boot?
That, I am not sure.
any reason you were going back to stock? there are many options to get you back there, which i could help you with but im just curious why you want to go back to aosp1.6?
