[Q] [SOLVED] Downgrade SPL on TMOUS - HD7 Q&A, Help & Troubleshooting

Hi, I was just wondering if the method of flashing the Europe ROM to downgrade a 5.10.x.xx SPL could be safely used on a TMOUS phone without unlocking.
Thanks so much for the help, and by the way-I'm not a noob, and actually used to develop very popular Android ROMS. I just decided to move to XDA because of the lack of communication and inefficiency of almost all of the forums I've tried.

if you are referring to SLSPL by ansar, no.
if you have a NoDo restore from Zune, then try this here.
else, you might try this here.

That is what I was referring to, I thanked you, and thanks for the help! Does that mean it would be possible if I unlocked the phone first? I don't have a NODO backup and didn't have any success with the goldcard method, so I would rather just pay for an unlock or call T-Mobile (probably the latter) Thanks again.

to what unlock are you referring to..?
TMO can only SIM Unlock your device... that won't enable you to change Bootloader or install non-Marketplace apps.

I actually am referring to a SIM unlock. The thread tells about how two SIM unlocked TMOUS users were also able to use the same method. I was just asking if this SIM unlock was required, possibly because a Europe ROM would have to be flashed. Thanks again!

SIM Unlock isn't required to change ROM, only XSPL.
did i understand you correctly?

This is quoted from ansar's thread: "Update on 30.12.2011: Two TMOUS users did confirm that after SIM unlock it worked for TMOUS too!!"
The XSPL is what needed to be changed- downgraded from 5.10.x.xx
The method used to do this is flashing a NODO Europe rom with the lesser-versioned bootloader.

i haven't been following the development of SLSPL, but if that is the case, great.
though, i, myself, wouldn't attempt it.
best of luck to you.

Thanks for all the help

If you got your phone from a carrier i.e. with a contract it is most likely locked to that carrier.
SIM lock means that you can only use SIM cards from the carrier you are locked to. If you SIM unlock your phone you will be able to use sim cards from other carriers or pay as you go plans without receiving the invalid sim message.
CID Lock means that your phones software is locked to your carrier. This means that you can only flash updates from that carrier. No custom flashing, no cross carrier flashing. Before you flash anything from this forum you will most likely need to be CID unlocked. Read the stickies to find out how to do this. Make sure you follow all the steps. The process works.
If you have not personally CID unlocked your device you must assume you ARE CID LOCKED. Even if someone before you unlocked your device it will not hurt to do it again. If you have any problems flashing your device this is the first question back that you will get when you ask for help.
god dammit. there is a wiki and nooooooo one reads it.

Great advice and gently put....!
Asking questions is ok but do your research 1st! 90% of what you need to know has already been discussed, so the answers are here. If you don't find an answer, by all means ask...it is a forum.

You won't have Hard SPL.
Carriers don't ever make Hard SPL's, xda-developers do.
Some prototypes are SIM unlocked or Security unlocked, but they will still have an SPL that requires a signed and matching CID image before it will flash it.
Thanks
Dave
Thanks for your response
And...Yes, my phone is SIM unlocked or Security unlocked

what happen if unlocked phone is rooted and upgrade to custom rom

i buy the phone HTC DREAM from the internet (i'm from malaysia) so i don't have T MOBILE SIM, but it's already unlocked.
what happen if i rooted or flash the phone with custom rom such as JACHeroski and etc.
will the phone become locked again ??
if the phone is locked, can i still able to like root and flash the phone ??
a rooted phone with custom rom, can eliminate the unlocking process ???
thx in advance

No. A custom ROM wouldn't lock or unlock the phone. It can be unlocked for any SIM and still be stock firmware, it can also be unlocked for any SIM and have a custom rom.
The two things are completely different.
Hope this helps.
You can do whatever you want to any rom, and that won't affect anything that makes it unlocked
thx for replying,
so meaning, currently the phone is unlocked, and i downgrade to RC29
so it wont be locked again ?
because need to downgrade to root-ed the firmware....
is this mean, downgrade my unlocked phone firmware to RC29
in the process, it will not reset my phone from unlock back to lock status ??
if it will not make my phone locked back again during the process
and i success downgrade to RC29 i can gain root access, then i can update to custom firmware
so another question, in the upgrading process (flasing to custom firmware or cupcake 1.5) will it set back from unlock to locked ??
sorry for my bad english
appreciate for replying, i need to know before i done anything
in the process,
Hi. I also have an unlocked phone. It was unlocked prior I downgraded it, and flashed new custom roms, and it is still unlocked. As the others said no need to worry, if i'm right the locking thing is in deeper level. Of course everything you do with your phone is your responsibility.

Can T-mobile still unlock the phone after I rooted it or would they know that I put a custom rom on it??

Yes, you can still unlock it through T-Mo. No one at T-Mo needs to have physical access to your phone, they can give you an unlock code over the phone.

One has nothing to do with the other. ROMs have nothing to do with the SIM cards and SIM cards have nothing to do with ROMs. T-Mobile isn't going to come to your house and spank you for having a custom ROM because they "know"

[Q] Chevron Unlocking

Hi, I just recently bought a HD7 and I'm new to the Windows Phone OS.
I'm curious on "Chevron Unlocking" my HD7.
My current system is "7390"
Am I able to Chevron unlock my phone, or is it too late?
If I can still, could someone guide me the way to do this?
Thanks in advance.

Hello, as of now, no unlocking method exists for 7390 firmware, but some people are working on it http://forum.xda-developers.com/showthread.php?t=1078007
If you want your device unlocked, you need to flash a 7004/7008 rom, after which you can apply the chevron hack. You can find the rom in the hd7 rom development forum.
After you downgrade to 7004,you have to use the prevent unlock xap, after which you can update to 7392 in the unlocked state

How can I tell which ROM is 7004 or 7008? All the ROMs in the ROM section all have ROMs have a bunch of numbers. Can you guide me which one will fit me? My carrier is T-Mobile USA

[Q] Unlocking device questions

Hey guys I apologize if this has already been posted but I cannot find exact answers I am looking for.
I have an HTC One carrier locked to Rogers running Maximus HD 42 4.4.3 with S-OFF.
To unlock my device is it as easy as purchasing an unlock code from a trusted site? If so which one do you recommend?
I read that prior to unlocking the device may have to be brought back to stock was not sure if that was 100% thats why I am asking. Thanks

Yes you should be on stock rom to use the unlock code, It could also work on close-to-stock roms. You have s-off which mean that if the unlock code doesn't work on your custom rom, it will be very easy to return to stock rom using the latest ruu. 4.18.502.7

So try the unlock code if it doesn't work then just try downloading the ruu 4.18.502.7 and flash it? Sorry for questions
