Downgrade dev GDR3 possible? - Windows Phone 8 Q&A, Help & Troubleshooting

Has any been able to do a successful dev GDR3 downgrade? I have an ATT Lumia 920 that was flashed to the Rogers rom for Amber then I installed GDR3 and now I am getting sim error: card is missing (tried a new sim and that didn't work and a reset). I tried flashing the Rogers pre-portico and I am getting the Platform ID doesn't match the ID of your product. Any help?

[Q] Sim Unlock Code Not Accepted

Hi,
I have HTC one on Three UK network. I took Sim network unlock code from 3 different paid servers, All have given same code but code does not work. It says Sim Password incorrect. Spoken to supplier and he said it is some bug in new android system. Can anyone explain me how to fix this. I appreciate that.
I already 3 tried another source and checked imei etc.

Are you on a custom CID ? On a custom ROM? If yes, change them back to the original and it'll work.

No it is original rom, original recovery but still not accepting. In attempt to flash i loaded up custom recovery now but unable to find any stock rom ruu on three. Hbot is 1.54 and s on and bootloader locked (i unlocked it using htcdev now)

This is purely anecdotal but the phone I had before this was the s2 LTE model on AT&T, when they gave me the code it kept saying it was unsuccessful until I ran out of attempts. However when I actually put in a t-mobile sim card it worked fine and it was fully unlocked. Maybe try that?

You do know that to unlock the phone you need a SIM card from a different company inside the phone so that it asks for Network Unlock Code... SIM Lock is not the same...

Obviously phone is asking for sim network unlock code when we put non accepted sim card. So phone is not unlocked. We do quite a lot unlocking and few phones get this error, we have to refund customer but I am seeking solution for it. It is only in Android phones (HTC and Samsung).. Samsung's we usually unlock using unlocking boxes but HTC One is not supported other than code. (Setool support older HBOOT).

AT&T HTC One on Vodaphone in NZ

I'm from the US and am in New Zealand for a month. I own an HTC One which I purchased from AT&T and have been using on their network in the States. I've unlocked the phone, and also have S-Off. I've purchased a prepaid SIM card from Vodaphone in New Zealand. When I insert the SIM card, the phone asks me for the 8 digit SIM unlock code, so I entered the 8 digit PUK code provided by Vodaphone with the SIM. The phone tells me this code is invalid. I'm not quite sure why this isn't working - is it possible I need to load a different firmware to use the phone in New Zealand?
Kernel is 3.4.10-g31f7883
Firmware looks like 3.62.401.1
I'm currently using ViperOne ROM.
Certainly appreciate any input on this issue.
Thanks,
Josh
Well, I did not realize that bootloader unlock and SIM unlock are two different things. That's a bit confusing. Wish I had figured that out prior to flying here.

If I remember correctly (this is all from memory), for the unlock code to work, you need
1) correct (original) CID and MID
2) stock ROM (some were able to do it on custom ROMs, but not sure if all work or only certain ones)
3) stock firmware for above ROM
4) stock recovery
5) LOCKED or RELOCKED bootloader
6) S-Off won't matter, and that will be your ticket to unlock again
you can search the forum here for SIM UNLOCK, there are quite a few similar cases, which got solved by a combination of points 1 through 5.
If anyone stumbles onto this thread in the future...
Turns out I needed a code from AT&T, as I needed to carrier unlock the phone before being able to use the Vodaphone SIM. I tried contacting AT&T to get the code, but they won't give it to you unless you are out of contract.
I was able to get an unlock code using option 5 in this thread:
http://forum.xda-developers.com/showthread.php?t=2242473
I loaded a stock ROM, but left the bootloader and my custom recovery on there, and the unlock code worked just fine.

[TRIAL] T-Mobile S6 Permanent Unlock by Code

After doing some research and doing a little bit or reading, the HTC ONE M9 T-Mobile variant has the same unlocking issues as The T-Mobile S6 and S6 Edge where the software only allows for an unlock through the unlock app and will reject any unlock codes. However, flashing the International model's firmware will rid of this road block and allow for an unlock (HTC ONE M9). I wanted to try the same method with the Galaxy S6.
Wanted to ask if a brave soul who has rooted and flashed TWRP on their T-Mobile S6 could buy an unlock code, flash the XtreStoLite Pure Edition rom from the regular S6 forums and try unlocking the phone with the international rom on it. Again, this method worked with the TMobile HTC ONE M9 and will likely work for the S6. I would try it myself but I have the edge and we dont really have any ROMS at all.
Also a heads up, if you do try and it doesn't work, wait until the dev of XtreStoLite Pure Edition updates the rom to add back some important files. it may be missing some important system APk for the unlock just like its missing important APK that enables LTE
I was thinking this exact thing. I wonder if it will work...i mean if it worked on the HTC One M9, it should be the same in this situation. Also since its just a software thing, i wonder if there is a flag we can set to trick it into being unlocked as well. Thoughts?

Tried this already and it does *not* work.
All codes are unsuccessful with unlocks.
We need kernels!
Of course if I were in the market for the M9, I'd just buy it from ATT since its bootloader is unlockable from HTCDev. Or did they change that too?

Still works the same.
Can we flash international firmware?

Ktoonze posted a kernel yesterday - I have not tried flashing the International rom yet - someone said data is not working on it when flashed on N910t? but would love to try to unlock if data is working?
Yeah cant try this myself since the 925t doesn't have any custom roms yet. :-/.

Failed at writing NVRAM.
Tried the Xtrelite rom and did get prompted for code but the code (from cellunlocker.net) did not work.
I dunno, I have a new IMEI since I swapped for an edge. Just going to wait this out and see if it activates in two weeks once the "remorse period" passes.
Do you think it would have worked if you had used the same IMEI that you purchased the unlock code for???

Go to www.sammobile.com and download the latest firmware for metro pcs s6 (SM-G920T1) and that should work for you. according to sammobile tmobile and metro pcs received updated firmware on the same date. downloads on the site take quite some time though, just a FIY.

What would happen if I flash Lumia 635 rom to Lumia 630?

I have Lumia 630 (RM-976) and it doesnt support 4G. If I flash Lumia 635 (RM-974) rom to my phone what would happen? Has anyone tried something like this? Can I get 4G support?
You won't be able to, either the FFU signature checks or the platform ID check will fail.

Even I change model info using registry? I saw a topic about unbranding at&t lumia 635 devices with flashing rm-974 rom to rm-975.

FFU flashing doesn't use the registry, it uses the platform ID which is related to files in the PLAT partition. (contains ACPI tables and other configs)
FYI, a friend of mine ****ed about with PLAT partition and hard bricked his lumia. So it would be a good idea if you did not mess about with PLAT partition at all.

MetroPCS L640LTE to WM10?

Ok, I have in my possession a Lumia 640LTE from MetroPCS and I would like to get it Window Mobile 10. I've already unlocked it from MetroPCS (got the unlock code and put in a non-MetroPCS SIM and entered the code).
I've been going through the forums and I can't quite determine the best method to go about this? That is also the easiest, sure fire way (no bricking). The only thing I have done so far is use WPInternals to unlock the boot loader, and I've tried to put "RM1073_02166.00000.15084.41001_RETAIL_prod_signed_1005_01DE1D_000-CA.ffu" on, but it fails via WPInternals.
I'm sorry if this is such a Newbie question in advance. Just please point me to the proper thread. Thanks in advance!!!

Unfortunately, it says there are "no updates for this device". Which is the same thing when I try the upgrade advisor. This has been an issue with this phone since it was from Metro PCS, as they never allowed WM10 for the Lumia 640 LTE
Flash a diferent variant then.

Could you recommend a different variant? I'm not sure which ones were allowed to be upgraded to WM10 in English besides the "Retail" version (I think).
The phone is the following from (w w w.lumiafirmware.com/ser/RM-1073/guid/059X0M9):
Phone model: Lumia 640 LTE
PackageTitle: RM-1073 VAR NAM US METROPCS SL
Product Code: 059X0Q4
manufacturerHardwareModel: RM-1073
I used RM-1073 VAR LTA 7R CV on my T-Mobile 640 LTE then used the OTC updater tool from Microsoft to push the update to my phone. I only use it for a Wi-Fi device though so I don't know if cell/data works or not.
