[Q] not able to downgrade to 5.1xxx htc mozart...please help

hi everyone, i got my handset a few days back as i exchanged with one of my friends. the tricky part is that its not locked to any network and i am not able to get what should i do to downgrade in order to flash custom rom. what i got from goin to all the threads is that u need to downgrade before u do rspl/hspl. for downgrading i need to get a proper rom. i tried perfect rom by ansar, and a few others too..
this is my first post to any of the forums..... so please dont disappoint me and try to help me out thanks.......
details
os version. 7.10.8773.98
firmware revision no. 2250.21.51205.707
hardware revision no. 0004
radio software version 5.69.09.05a_22.50.50.21U
radio hardware version A.102.0.D4
bootloader version 5.12.2250.5(139188)
chip soc version 2.2.5.0
it would be great if we exclude the way in which a Y cable is needed. if that s the only way out then let me know which rom to use with this handset????
thanks in advance...
hi, the only way is y-cable and goldcard. this is a good tutorial: http://forum.xda-developers.com/showthread.php?t=1597837
you need a asian rom . the tutorial provides a link for a rom collection. there is only one asian rom.
thanks for the link....

thanks vincent
Will try this as soon as possible. One more thing i wanted to ask. I ve seen some place how to change the internal memory card of mozart. If by any chance we able to replace it by gold card, will that be able to downgrade? I know it sounds crazy but still is there a chance
By the way
happy new year to u n all........
Try flashing the SLSPL rom by ansar and then any rom 1.xx
ansar´s slspl rom is a europe rom so don´t work. is the phone operator branded ?
SLSPL doesn't work on my French Orange Mozart. I had to flash an Orange rom vers 1.XX to downgrade the SPL with the Y-cable solution.

Hey buddy , thank u for helping . Could u let us know , did u pay money for ur phone to be flashed or not ? Because as u know rooting phone voids its guarantee . By the way , i havent tried them because after that i need unlock code and huawei hasnt sent me any code yet . So i prefer my phone to be rooted instead of having my bluetooth working and unfortunately there is no solution for rooting u8950-1 yet . Im wondering why they dont email us any unlock code for u8950-1 but they have sent to people unlock code for u8950d . Did u ask huawei service about unlock code ?

i didn't paid anything.i think they were so kind with me and didn't avoid my guaranty.
you can unroot your device then take it to service center.
or flash one of that ROM on my previous post.

Hi everybody,
I try also to find an original firware for my u-8950-1, I downloaded the V100R001C326B953 firmware but it doesn't install on my phone (i have U8950-1V100R001WEC00B942).
The 3 firware versions are only work with Czech phones i think.
Anyone have link to other official firware? I try google and of course huawei website but couldn't find anything.
Thanks for your help guys.

First of all, never, ever do duplicate threads on a forum, and this forum ain't meant for troubleshooting. The correct forum would have been EVO 3D Q&A, Help & Troubleshooting, where you already had one topic regarding EXACTLY THE SAME problem. Read the forum rules since this here, is lame...
3.28 means ICS, so get the appropriate ruu. Most likely* you will need the European RUU from there http://www.androidruu.com/getdownlo...00U_11.25.3504.06_M_release_262714_signed.exe
Thank me later. And your bootloader must be locked prior to flashing the ruu and to flash the ruu you must have the adb drivers and your phone in fastboot usb mode.
Thank you so very much,,,srry but i have bad internet connection its only for aboute that....i go to try that,,,thx..

Post the exact file name of the RUU you are trying to run.
What versions Windows (7, 8, etc.)?
Are your ports USB 3.0?
I've seen this issue posted a few times. I don't know if a solution was ever found; and you may need to try on another PC.

Thanks for replying. The exact file name for the RUU is : RUU_M8[email protected]50319A_40.45.C33065.00_F_release_426617_signed_2.exe
iam using Windows 7 32 bit and the usb ports are 2.0
I have tried it with other computer but with no luck
Try downloading the RUU file again.
Try running the phone in fastboot mode, if not already.
Other than that, those are the only ideas I can think of.

The following just got bumped. I forgot dottat made a zip version of the Lollipop RUU. Give it a try: http://forum.xda-developers.com/att-htc-one-m8/general/exe-zip-ruu-m8att-4-4-4-s-off-onlynewest-t3015680
EDIT: Oops, realized the above RUU ZIP requires s-off, and the OP has s-on.
