Downgrading your Bootloader to OEM - 8525, TyTN, MDA Vario II, JasJam Software Upgradin

Well I just thought I would put this information in one place as I was not able to find a really good explanation of some of it and the rest was burried about 75 pages deep into some threads.
For those of us who are using the newest version of Oli's bootloader, you will notice that no matter how many times you flash the device it never overwrites the bootloader. If you are sending in a device for warranty this can be an issue. But there is a way to do it though it is not readily apparent. The newer versions prevent the bootloader from being over written so you have to downgrade to an older version then upgrade to your OEM ROM package.
1) Download the 1.10 - Olipro SPL
2) Flash the bootloader of your device with the 1.10 bootloader
3) Download the OEM Flash for your device, either from your OEM website or check here.
4) Then Flash your device with it and all should be back to what it was before ya started flashing your device.

An easier way: from olipro's sticky:
-SPL protected from all HTC retail SPLs being flashed by accident (to bypass, use SSPL)

If you have radio bootloader 0108 on your device (ie, a radio version > 1.27):
- If the shipped rom you're flashing has radio bootloader 0106 you will end up with a brick (no GSM error).
- As you're using 1.10.oli (which is based on 1.04) to flash your device, the original shipped radio will not be flashed (needs SPL >= 1.09). You'll have to flash it later with SSPL if you want the radio on the shipped rom to be flashed.

Worries about Upgrading

I will soon have a Cingular 8525. I was thinking of upgrading it to the South African ROM. The one with the 1.09 bootloader.
I know the phone will have either a 1.04 or 1.06 bootloader so I can definitely unlock it, but I am looking for a full procedure thing. There is a lot with this, such as not being able to downgrade from 1.09 to 1.04 (which I found out you can actually do), and getting the SuperCID working, etc.
So could somebody be so kind and write up a procedure so I dont screw up a brand new phone. Thanks a bunch.
I second this request.
Actually I have read quite a lot about this on these wonderful forums by wonderful people but I am still not confident and therefore want to ask some specific questions:
1) My Jasjam original ROM is with bootloader 1.06. On the I-Mate site there is a ROM available with bootloader 1.04 and having the same CID as the one currently on my machine. If I install this ROM will my bootloader change to 1.04 from 1.06??
2) If after installing the ROM with bootloader 1.04 I attempt to install any other Hermes ROM say the Dopod ROM will it be possible simply by connecting my device with the computer through active sync and running the installation file on the PC?? Personally I think this will be possible as the bug in the bootloader 1.04 will allow me to do so.
3) My last question is that if after installing the i-mate ROM with bootloader 1.04 I install another ROM with bootloader 1.09 will I be permanently stuck with the bootloader 1.09 and afterwards not being able to install any other ROM.
I know some of my questions may sound foolish but I need the answers to gain some confidence that I have understood what I have read in these forums.
Kind Regards
@staulkor:
- Downgrade to cingular 1.30 rom to have bootloader 1.04 on your 8525
- Follow unlocking process as explained in the Readme file
- Double check that your radio version has changed from 1.13 to 1.16 after flashing the patched radio, once you're running the patched radio run Herm_Unlock_v2a.exe to SIM/CID unlock your phone.
- Upgrade to cingular 1.34 ROM again if you want the original ROM back on your device
@srmz:
1. yes
2. yes
3. yes, but read this
Thank Pof. I have heard much about you and all of your greatness throughout these forums. Thanks again

Hot to downgrade raido 1.29.00.11?

Please help!
I have upgraded raido 1.29.00.11 form "Experimental", now I can't change radio to any version.....
How can I do?
Thanks
You've Probably Flashed Radio Bootloader 108 On To Your Device.
This Means That You Will Not Be Able To Flash Just A Radio Rom Any More. You'll Have To Flash A Whole Rom Just To Upgrade The Radio. There Are Notices About 108 All Over The Forum

If you accidentally flashed your Radio Bootloader, how did you go back to the previous version.
My guess is that you were already SuperCID and you had to load a complete older ROM to get back. Am I correct?

Yes, I had SuperCID.
My method was upgrade to latest ROM (Include SPL-1.09) and twice successive flash.
First, SPL will upgrade 1.09, but radio still 1.29.00.11
Second, Radio will upgrade 1.34.00.10
not quite. Your radio bootloader is not downgraded. You can no longer flash radio in nbf with bl 1.04. You must flash in nbh using bl1.09. Then you can downgrade bootloader to 1.01MFG and flash os/extrom of your choice.

So he can change radio or not?
He can change. But he must start with a specific Bootloader and flash a full RUU in nbh. Then he must put on BL1.01MFG and flash seperate os.nb and extrom to change to the os build he wants. The "radio only" upgrades flash in nbf and will not work any more.

ok thanks, i'm iterresting for radio upgrade only (after bigggg mistake Flashed HTC_BOOT 1.08).
SO no issue for me now:-(
The key here is that Bl1.09 and radio bl 1.0108 work together. 1.09 will not allow the radio to upgrade unless flashed in NBH. Radio bl 1.0108 will not permit upgrades unless initiated from bl 1.09. If superCID is enabled then bl 1.09 will permit any operator's rom, flashed in nbh, to upgrade the radio.
I really need to flowchart this for the wiki... I barely understand this myself...
but why, after restoring all, bootloader 1.01mfg etc. it is still impossible to flash radio rom only?
i can´t get it.
Actuality, I used this ROM "RUU_Hermes_HTC_WWE_2.05.255.1_6275_1.34.00.10 _108 _Test.exe".
After flashed, I don't change SPL to 1.01 MFG or 1.04, just re-flashed it again.
The radio will be change 1.34.00.10.

Device BL 1.09 acts as the "key" for Radio BL 1.0108. By flashing to Device BL 1.01, or any other, you have broken the "key" and now can't access the radio rom...basically.

radio bl 1.0108 won't allow upgrade to occur unless initiated by bl1.09. bl1.09 won't allow radio flashing in nbf (which is what all extracted radio rom only files use)

PLEASE??? Radio only upgrade questions...

I've read around the forum and wiki, and it is not clear to me the requirements of upgrading only the radio. My questions are:
1. I have a cing/Att 8525, running the latest WM5 release by att/htc from htc's att site; My phone has not been sim / cid unlocked. Can I upgrade my radio only without unlocking the phone? I upgraded to the official ATT WM6 release from this site, but I lost sync functionality for Microsoft Money for PPC; this is 90% of the reason I bought the phone in the first place, so I'm going to go back to the WM5 release. However, the 1.48 radio in the WM6 release gives me better reception. So, can I upgrade the radio only in the wm5 release w/o unlocking the phone (which is still under warranty)?
2. If the answer to 1 is yes, the second question is that if I clear storage and reformat the phone sometime in the future for warranty purposes, will the radio revert to the WM5 version?
Thanks in advance!
Yes you can flash the radio ROM only. Have a look at the wiki for instructions and download links to extracted radio ROMs (including 1.48). You do not need to unlock your device but installing Hard-SPL first is a very good idea if you want to avoid having to make a call on your warranty.
Yes you can downgrade by flashing over another radio - provided that it (like 1.48) uses radio bootloader 0108. If it uses an older bootloader version you will not be able to downgrade at all. You can check which bootloader version is in use on the wiki page listing radio roms. However, I wouldn't worry about it for two reasons: 1) if you can't downgrade you are stuck on 1.48 now anyway (anothe reason you ought to have Hard SPL installed as a failed downgrade may brick your device); and 2) virtually all official recent WM5 updates will include a radio sufficiently new that it uses bootloader 0108.
U R The Man....
I had read and read and read, and finally stepped out on a limb and did exactly that (hardsplv7, and radio rom 1.50) Prior to reading your response. but you actually answered my remaining question, concerning my warranty. I greatly appreciate your response.

But if you follow Mrvanx's guide to downgrade the SPL to match your radio version, this should also work not so?
The "radio bootloader" is part of the Radio ROM image, and completely separate from the main SPL bootloader. Once you are on a Radio ROM that uses radio bootloader 0108 you can't downgrade to an older radio bootloader version.

Ahhh, ok sorry, i got a bit confused between the bootloaders.
Thanks for the reminder ma499. Really appreciate it!

phone is stuck at htc screen and it says no radio

i installed the wrong rom on the wrong hard spl. i had the hard spl a 1.30 installed and dcd 3.2.0. now the screen is stuck at the loading screen that says htc smart mobility. and no radio at the bottom. please help and the phone wont sync.
Good luck on that.. You installed a bootloader for a different model -- likely the TyTn or Trinity. What phone do you have? What instructions did you follow?
If you do have a Titan, then possibly via the SD Card you can change the bootloader to the new 2.47 (I haven't played with it yet but another may provide a solution). You are likely out of luck in flashing to any of the other Titan bootloaders as you must be able to boot into the OS, but with you error of installing an inappropriate bootloader you are out of luck there.
no it was a bootloader 1.30 for the titan
Your information is incoherent.
What rom/bootloader did you have prior to updating?
What rom/bootloader did you try to upgrade to?
You need a minimum SPL of 2.40 to install DCD 3.2.0
I use 2.47 from no2chem and it works great. http://forum.ppcgeeks.com/showthread.php?t=30561
Are you able to boot up the device? If so copy the SPL 2.47 to the card then to the PDA and run it from there.
If not, put the PDA into Bootloader mode and try to install Olipro 2.40
http://www.lifesnotsogood.com/dcd1182/titan/spl/titan_SPL_2.40-olipro.exe
Failing that you can try to flash back to an official ROM if you have one.
You need to soft reset your phone while holding the Camera and power buttons. This will force your phone in to the bootloader. You should then be able to reflash to lower ROM. Then you need to search for Olipro or whatever the 2.40 bootloader is. Your best bet after that is to flash the official Sprint 3.35 Radio and Rom then flash to DCD's.
**Edited**
Sorry Hamilton didn't realize you gave a link to the 2.40 bootloader.
If he is sure that it is "bootloader 1.30 for the titan" then I know of NO such bootloader. He has likely installed the wrong bootloader (for another device) and therefore no amount of flashing to an OS ROM will help him boot into the OS. Unless via an SD card for 2.47, beastmode216 is stuck with a borked device.
So, beastmode216, I'll ask again, where did you get such instructions and where did you source your bootloader 1.30?
What is one of the earlier bootloaders? I was thinking my Mogul orginally had something like 1.30 or 1.40.
thanks guys but the problem is solved. just make the phone go in to the bootloader
Verizon stock bootloader is 1.30 if I remember correctly. It has been several months since I have seen a stock bootloader

My mistake, as pointed out by gc14 the stock bootloader is 1.04.
Ahh, ok, my fault as I thought that he had also installed a bootloader under the name of 1.30.. That could've been an unlocker for a TyTn or another device.
Correct, OEM bootloader should be 1.30.60.

This is incorrect. The stock bootloader is 1.04. The stock radio is 1.30.60.
SPL 1.30 does NOT exist for the Titan.
Stickies exist for a reason...to read them as they contain valid, useful information. http://forum.xda-developers.com/showthread.php?t=392133

Few questions about roms

Hi guys,
I´ve read a lot of posts here at xda.
But i have few questions before i try to upgrade.
First of all, my RADIO version is not listed anywhere here. It is 1.58.21.26. So if i SuperCid it, is there a problem to put another radio version?
2 - If i install another ROM(original or cooked), is there a way to go back to the default rom that it´s in my phone? even after i installed other radio version?
3- supercid, hardspl, sspl or uspl? wich one is better or keeps my original rom and radio??
Thanks!!!!
1. If you CID, and use HardSPL (1.22 latest i believe) you should have no problems flashing new Radios or ROM's.
2. When you flash a new ROM your current one is over written (after you have flashed it you have to set up the OS again - all data stored in phone memory will be lost).
3. They are all different Things. HardSPL permanently updates the SPL on your phone allowing you to flash a new ROM when ever with bricking your phone. SSPL (SoftSPL) allows you to flash a new ROM (or radio, or hspl) 1 time then returns to the normal SPL. uspl, I'm not sure about I have never used it before. and CID unlocks the device to all networks and allows you to flash any ROM (rather than just ones from your carrier or official HTC ones. NONE of these will preserve your ROM if you flash a new one. however if you just flash these bits they should not effect windows or your radio.
DO NOT put a new ROM on your phone until you have unlocked it and put HardSPL or SoftSPL on it. If your brick your phone its near impossible to get it working again!
Questions before proceeding.
My HTC NIKI100 was unlocked for any carrier through the IMEI code, it also has the original radio 1.58.21.26. Perform the installation process of HARDSPL 1:22 as the tutorial here: http://forum.xda-developers.com/showthread.php?t=355730 and got success! now I can put a new radio or need to do the procedures as SuperCID here: http://forum.xda-developers.com/showthread.php?t=395945 ???
