FREE XDA

[einas_canada]

Hello all,
well it is not 100% free, you need to earn it.
The price is to allow me to downgrade the RSU to 4.16
I am unable to do this and have tried so many things so far without any success.
I have RSU 3.23 now

ROM wise, I have no problem, I can change it using the SD method and the ismgtool.

Well, I am sure you will ask, what is the guarntee? Tkae my word for it for the time being and try me.
You can send me a private message or e-mail me (einas_canada@yahoo.com)

If I receive the solution from more than person, I will look at the time I have received the pm/e-mail and the prize will go to the eriler responder.

HURRY :!:

Hello

as far i know and if my memory still works i read something which says you Can not roll back to older version and that was on the 3.23.01 release note.

HTC Advice not to try to downgrade your GSM cause you might distroy your device and lose the GSM capabilities.

also few other issues include

Fixed: SIM unlock code hacked
1. Disable memory dump function.
2. Unlock code encryption.

Fixed: Do not auto-reactivate PDP context when network reject PDP context activation

Fixed: Specific message should store in SIM without affecting the VMI
Solution: Change the DCS of specific OTA message from 0x00 to 0xf2 (Store message to SIM)

Fixed: After dail a wrong number, dail second call with correct number within 30 seconds,
this call will be established for 2 seconds, then be automatically cancelled.

Solution: ACI state is not syncronize to MMI state. Syncronize the state of ACI and MMI.

Fixed: USSD Problem

Fixed: Inter-SGSN Issue

Othman,
are you replying to a different topic? :?
What is the relation between what you have written and the downgrading issue?

Place adaptrom.exe in the up or down grade application folder.
run adaptrom, then the up or downgrade application.
This will change the rom as well as the radio stack.

[falconeyez]

you can send me the device, i can run over it with my car, get AT&T to replace it with a new one ( I have insurance from them) and BAM! start from scratch

[JoshB]

OK, how about this:

1. Obtain the RSUpdate.exe and accompanying files for the radio stack version you want to upgrade/downgrade to.
2. Copy them to the \Windows folder on your device
3. On the device (use File Manager), run RSUpdate.exe. This will manually update the radio stack.
4. Send the free XDA to me, since a winner is me! :D

2JoshB: It is not so easy as you wish.
You may not downgrade 4.21 radio to 3.19 and below in this way (though it is Ok for greater versions). The restriction is by design and appears during actual uploading to radio module due to some kind of _internal_ checking.

I can suggest the following:
-convert RSUpgrade.cp64 you want to upload to binary format. Let it be 3.19 for example
-try to find 03 13 and 13 03 entries (= 3.19 in hex)
-If entries are exists -try to replace them with 04 15 or 15 04 accordingly (= 4.21 in hex).
-convert RSUpgrade.cp64 back to text
-try to flash these files in the usualj way (upload to windows etc...)

But this way is very dangerous. I mean that such a stupid replacement may corrupt radio stack code, so your radio will be broken completely.
More than that: radio stack version checking may be implemented not by number but features available in RSU. So version changes may not be enough to downgrade radio.

the more reliable way is to disassemble radio stack and bypas version checking in more sensible way. But unfortunately my qualification is not enough for doing this.
