Chance for cooked ROM with USBSwitch-App?

Hi,
i have the following problem:
i have used the Chevron tool to deploy the USBSwitcher App to test the debug mode...
i have used the tutorial to prevent my hd7 from relock, but that doesn't work...
The application has been revoked and uninstalled :'(
So im stuck at the debug mode with no chance to change the USB-Mode...
Could anybody make a C-ROM with that app?
Or is it possible to use the Bootloader-Mode to install an xap to WP7?
i hope that somebody can help me
im really desperate... :'-(
custom roms need access to HSPL. We dont have access to HSPL yet
So is there another chance to go back into zune-mode?
I've no idea. There seems to be **** all development going on for HD7. Custom roms aren't available yet. Maybe some one else can help ya.
Sent from my HD7
maybe there is a way that someone make a backup of his phone while the USB-Switch is installed...
then i have the chance to set the mode to zune-mode again when i install the backup!?!?!
hope that sby can help me
Srry for doublepost, but:
Does anybody having the same problem tried to flash another Radio ROM?
did it work?
Yes I know about you trouble.
The only way is to unlock your device, with a super cid.
My friend had the same expr., and solved it.
Super cid unlock will display "security unlocked" on your bootloader mode.

I already flash my device (HD7) with another ROM that match with my Firmware, unfortunately the mode is not switching to ZUNE.

how can we do that?
Sooo
i found out something interesting...
as this device is in qualcomm mode now i installed the Qualcomm Product Support Tool (QPST) and connected it...
it works...
so could anybody which knows that program make a backup of his phone (when the USb-Switch-App is installed) so that i can get back into zune mode?
Would be great to hear from you...
so now the first update is out...
could anybody give me an backup from WP7 with the USB-Switch App?
would be really great...
but be careful:
before you give the backup you must be sure that you don't have an live account assigned because i don't want to mess up anybodys mails (or even read it...)
would be great if someone could post an fresh WP7 backup with only USB-Switch app...
thanks

I dont know where you can find the SPL unlock service, in your place.
In China I only know one place named "Hua Qiang Bei" in Shenzhen City, which is one of the most biggest electronic market.
This unlock service only costs about 10USD, I have some friends bought HD7s from Shenzhen City, all T-mobile version and "security unlocked" shows on the bootloader mode. The devices are network locked when come from USA, I think this is the quicker way for the seller to unlock the network (SIM), by unlocking the SPL.
I heard that they use a set of HTC debugging or testing software to do it, which limited people know about it. Thats all i know.
oberoth, were you able to find a solution to your problem? I am in the exact situation and need dire help. I have spent too many hours trying to figure this one out.
Hi,
i haven't found s solution yet, but now there is RSPL/HSPL so maybe one of our great cooks can make a ROM with the USBSwitch-App?
Would be really great :O

I haven't tested this in a while but ViperROM had a way to access "Advanced Options" in their tweaking center. You might want to give that a try.

Thank you for the response. But I am not looking for the shortcode. But for the PIN once you get the Engineering Mode. When I tried to access engineering mode via the Shortrcut master Lite, The app is asking for the passcode. I will upload the screeshot if possible shortly.

Manufacture Mode for USB issues

So I decided to find the unlock code for my Huawei P20 Pro, and to find it I need to enable manufacture mode for USB settings. I tried to do that but it did not work, reporting "Not support at this state!". If I close the window, the changes do not save. What state - I didn't get it, if someone can explain to me what am I doing wrong and if someone can help me with finding the code, I'll be glad with any help I get.
Thanks for reading, hope you can help!

No, I sold off the P20 Pro. Stuck with my P20 lite, kind of regret my decision, as it was a chinese model and now it has harmonyOS support...
