[HTC U11  Questions & Answers] yanxinchao3:
Masters! Hello, everyone, I am a user from China, and I have gone over the wall and came to the xda forum.

Due to my limited level of English, I have read XDA's htc forum with the help of Google Translate, and the resources of domestic players are scarce.

After watching the S-on mode to modify the MID and CID tutorial I began to try

https://xdaforums.com/u11/how-to/how-to-change-cid-s-sunshine-t3888170/page4

I modified the three files sdf1 sdf2 sde1 in the /dev/block/ directory according to the above tutorial, and ran adb push sdf1 /dev/block/ in TWRP mode

adb push sdf2 /dev/block/

adb push sde1 /dev/block/

Then restart in the twrp mode and enter the download mode, and the phone cannot be turned on after a black screen

The previous state of my phone was

HTC U11 SPRINT version

s-on

Officially unlocked

Version is sprint2.33.651.10

The mobile phone now has various combinations of keys and all kinds of constant keys are all in the black screen state, I will show the picture

The problem now is to enter separately under cmd

fastboot devices This command can discover devices

fastboot getvar mid pop-up error message

fastboot getvar cid pops up error message

fastboot getvar all

So is there any other way to use fastboot

Return the modified file to the original directory

I changed the cid and mid to 5000 for the mainland China version

The phone is now under a black screen

Run fastboot flash radio

fastboot flash boot

fastboot flash boot

They are all fed back such information FAILED (remote: verify HOSD fail)
