[EVO Shift 4G Q&A, Help & Troubleshooting] rchris494:
Anyone successfully downgrade and unroot 2.77.651.8?

I flashed UU_Speedy_S_Sprint_WWE_2.77.651.8_Radio_1.08.01.0111_NV_SPCS_2.97_01206_PRL60674_release_275849_signed.exe

I followed indirect’s method. That did not work. Followed his method without the script.

Then I tried JohnnyCakeXM’s method with indirect’s.

Best I get is either caught into a bootloop or it just say’s permission denied

Here is a log of my output in command prompt typing each item one at a time

the only reason why i used shifty son of a. is because it had all the tools needed in one download.

i manually typed everything in.

C:\ShiftySonOfA>adb push tacoroot.sh /data/local/tmp/taco

adb server is out of date. killing...

With great assistance from Reid Holland (Erishasnobattery)

----------

TacoRoot: HTC Edition v1 is based on a vulnerability independently discovered by

both Justin Case and Dan Rosenberg (Rosenberg first). I believe unrevoked and

AlpahRev were also aware of it.

----------

Usage:

--recovery : For this exploit to work, you must have booted recovery at least on

ce after your last factory reset.

--setup : Setup the phone for root, must be done before --root.

--root : Root the phone.

--undo : Remove TacoRoot.

----------

Rebooting into recovery, please press Volume+, Volume- and Power at the same tim

e, and reboot the system.

rm failed for /data/data/recovery/log, No such file or directory

link failed No such file or directory

reboot: Operation not permitted

*REBOOTED INTO RECOVERY WITH HTC Quick Root v1.1.13. press Volume+, Volume- and Power at the same time and rebooted the system. once phone was back up and running i did the following.

C:\ShiftySonOfA>adb shell sh /data/local/tmp/taco --root
