How to Select the BEST SPL that matches your ROM
When I was reading the SPL Frequently Asked Question in the wiki.xda.developers I started to search on the topic more and more; I kind of got obsessed with the issues described there by bengalih such as battery drains, power issues, screen freezing see this http://forum.xda-developers.com/showthread.php?t=396235
I decided to shift from Hard SPL to Shipped SPL I was running shipped WM 6.0 [1.81.415.2 (radio 1.27.12.11)] at the time. So used the pre-made SPL file manufactured by sirsycho http://forum.xda-developers.com/showthread.php?t=335568 to return to shipped... my phone screen lagging got better and battery life improved slightly… the problem however persisted…
I flashed several ROMs Shipped/Cooked and kept moving between Hard SPLs and Shipped SPLs… my obsession has grown more with performance and between the relationship between SPL and ROM… I even posted a thread but it was closed as being redundant information
Last week I decided I will start doing some real experiments using sirsycho’s excellent guide… I was ripping the Shipped SPLs from Shipped ROMs and flashing them simultaneously trying different Hard SPLs on the Shipped Roms
I was noting the version numbers and apparently a very obvious correlation existed between the version of the SPL and the best ROM. I have observed that the first four characters (I am counting “.” as a character) must be the same to obtain the best ‘marriage’ between your ROM and your SPL
e.g.
If you have the Shipped ROM 1.81.415.2 (radio 1.27.12.11) your best SPL will be 1.81.0000
If you have Shipped ROM 1.56.405.5 (radio 1.27.12.11) your best SPL will be 1.56.0000
If you have Shipped ROM 3.29.707.0 (Radio 1.65.16.25) your best SPL will be 3.29.0000
Now transferring this knowledge to cooked ROMs your base ROM version will determine the Hard SPL you must use. Thus, why HardSPL v3.07, v3.28, v3.29 and v3.56 by JockyW2001 are recommended for WM 6.1 the next question that this thread is attempting to answer is which Hard SPL must be chosen
Concluding Remarks,
To Revert back to Original ROM and Original SPL (Make sure you get the right Couples) for warranty purposes
Cocked ROMs must get the best Hard SPL match for optimal performance
Don’t mix AT&T ROM with htc SPL or vice-versa (I did not try that but I assume poor performance)
Such information might be useful for Hard SPL developers – obviously it seem a new Hard SPL will be needed with each kitchen
Moderators
I genuinely have searched the forum very well before posting and never found any obvious information as described here

Battery life testing ROM, SPL, Radio
GREAT post, can someone sticky?
there really is some great information in here that i will also test out
thanks - please report your observations here
best wishes,

This is how Jocky created the new 3.xx HardSPL's. He ripped the original SPL from known good ship ROMs, and cracked them.

I use HardSPL 3.56, ripped from an AT&T base, with all custom ROMs I flash. There are no performance issues with HTC-based ROMs. All of the chefs will list the recommended SPL version in their threads, and they rarely match the SPL of the base they used.
-Edit-
Bengalih created an SPL thread covering this information back in May. But your thread seems to be more concise.
This is still very very useful and provides a nice summary and insight into SPL choices. Well done!
Mr. NotATreoFan
Hello ...
Definitly - JockyW did an excellent job in ripping the original SPLs and cracking them - i was just trying to highlight that SPL/Hard SPL version mut match ROM choice
Cooked ROM and SPL - Chefs don't always point to best matching SPL
About performance - i disagree with you and multi-tasking is the real test if a person use a bad match device becoming sluggish
As for AT&T SPL with htc i was just predicting, i did not tried this [but i do trust your experience]
Battery drain is another issue - i assure you if you use the best match power consumption (standby) increase - i will try to run a benchmark if time allowed
After all - any Hard SPL will work with any ROM (cooked or shipped) it will only need an obsessive person to complain about performance
Thanks for your insight

Not to be rude or burst any bubbles......
The info you provided is great, if you're flashing BACK to the official ROM for your device or carrier.
If I'm not mistaken, all official ROMs when flashed.....will change the SPL to what it's supposed to be. When doing a warranty return, the last step is removing the HardSPL.
Back to the question of the thread:
How to Select the BEST SPL that matches your ROM ?
The chef should/will tell you within the 1st 3 threads, if not....that would be a valid question to ask that chef in the appropriate thread.
Your SPL needs to match the ROM Build for best performance.

Exactly what I said, with the exception of your last sentence. Generally I would agree with you, but for whatever reason, my personal experiences with 3.56.Hard have been the best, regardless of what build the ROM came from.
hello...dwny...
yes - in most cases chefs will point to the best spl when they release a new rom - we are all aware of this fact (but let me ask this question, how many of us using the best spl? dude up to a one month time i was using Olipro Hard SPL with wm 6.1 and i was not the only one for sure... read the signing remarks of people and u will see them using bad spl, bad radio, with a good rom) pls look next time at this BTW my devices info ar out of date
this thread is aimed to answer the question [How to Select the BEST SPL that matches your ROM ?] by each one of us, as i have demonstrated above!
i will try to PM the figures of hard spl (Olipro and JockyW) to get their engineering knowledge on what performance aspect we speak about here.. spl (hard spl) is what save our devices from bricking and apparently it does morw than this - so lets have a better understanding of it

HardSPL allows us to flash whatever ROM we choose & will not uninstall with a flash
The best SPL is the one that comes with the base of the cooked ROM (so they say).
Due to screen freezing, matching the SPL w/ROM became the standard.
I, myself noticed differences when applying the standard. Before then, it was a crap-shoot. We all kept flashing or just dealing with the screen freezing.

I've been on 3.56 for a while also but the ROMs I've been on required it also except for one ROM and it didn't lockup on me.
Hi,
would it possible to port Dude's Cupcake v1.3 RC1 to our HTC Magic?
Is there someone who can do this for us?
For more information; look at this thread:
http://forum.xda-developers.com/showthread.php?t=507151
Thx
Kindly Regards
Puky70
I'll try it.
First of all, I'll extract the zip and change boot.img with the rogers boot...
And try if boots correctly...
----edit----
updating.....
fingers crossed.....!!!!
Just wondering how it went?
I tested it..installation aborts
Thanks for the reply, thought that might be the case as it had gone quiet. Maybe time for me to learn how to port ROMS!?
I would be very happy if someone can rewrite Dude's Cupcake v1.3 RC1. I would love to use it on my HTC Magic!
Greets from Germany!
After weekend tests I've ported successfully this rom, but...
Bugs:
First and important but: Wifi does not start...
I've changed wifi.ko file, but wifi doesn't work...
Maybe somebody can point me in the right way...
If anyone is just interested in the look of the screen shot in post 1 (ie. Hero)...
I thought i'd give tehseano & MOONSSPOON's hero theme (from the dream forum) a shot on the Haykuro ADP1.5H port for Magic as I had noticed that it had been reported to work on the Dream version of his ROM and it Worked!!!
Hi
I have one question.
What rom with SENSE UI on this forum is the least bugs and it is most similar to the original.
Double. See next post...
32A or 32B ?
If B I woud say:
- QTek as original Hero port
- ttran001's OTPA as SenseUI for Magic
Both are mature, very stable and clean ROM's. And have also Bluetooth partially working.
eVil is too striped and eugene's one is to customized (for my taste).
Because of very active development some bugs here and there...
32A most probably MyHero (haven't tried tough).
32A from orange
What do you think of GyD?
whats the deal with all this 32a stuff at the moment???
have the devs forgotten about us 32b users???
more 32b pleez!! is all i can say!!
32 is just that much sicker
whatzz the deaal withh all theese "???" in the development section???
have the users forgotten about the time of us 32b devs???
more brain pleez!! is all i can say!!
(Sorry for that)
Go to the Dream section. The majority of roms will work with 32B. THAT'S why there is so much 32A.
Ex. Cyangenmod: UNIVERSAL! Runs on both Dream and Magic 32B

Because its that much better! 2x flash memory etc... etc... etc... Dats why 32b needs the apps2sd crap. If it was'nt for the dream as a dev platform 32b would have been dead ages ago... but, don't woryy 32'bers still have the luck of having all the new stuff first so i don't know what your complains are about.

Competely wrong.
Memory is exactly the same. Just RAM is different.

Sorry maxisma.. did'nt want to offend you. I was referring to dream, but for the record...
Dream : 256M flash & 192M ram
Magic (32A) : 512M flash & 288M ram
Magic (32B) : 512M flash & 192M ram

32B always had and still have the most development going on.
But its because of guys like you they are else where now, guess they got tired of people cluttering up their developer thread with things!!!

you been flamed enough, but the deal is because most roms in the dream forum works on 32B devices. They do not on 32A devices, we have to wait for someone to port for us. That is why there are not much specific 32B, cuz u can just go into dream and take any rom you like!
I'm running fasttest v3.03 and i want to upgrade to 2.1 build but everytime i do its so slow and lags. I would like to know what the newest radio and spl are and was wondering if i upgrade to a new radio and spl will this help the performance. Right now i have hard spl and 2.2219.26i. Thanks in advance for any help.
Please check the forum threads and use search before posting
http://forum.xda-developers.com/showthread.php?t=605239
thanks for the help but the link u gave me sends me to a radio and spl that are only for 32a this dosent help me
Those aren't even the newest.. but if you tried to do some reading instead, you would understand that radio and spl have nothing to do with the performance of 2.1 roms. So don't bother changing it. It's missing drivers
