[HTC Sensation] kgs1992:
Problems?

[Last Updated on: 8th September, 2012]

I've seen how everyone struggles with the wire trick & I'm posting to put up some useful info for you'll since the JuopunutBear IRC channel won't support the temp root method unless your bootloader unlock is not supported.

About the temp root:

First & foremost, you need to understand that you are using a method that may take a lot of tries to get the wire trick right.

So, you need to be patient. If you are calm, then this will be easier.​

CAUTION:

If your wire/paper clip is not insulated or wrapped in some insulating material, insulate it first.

Hold the wire on the SD case & tap into the hole. This the right way to do it because the SD case is ground; the other way round is risky!

When can you close CB or disconnect USB cable:

Sometimes, people forget to do something important like removing the back cover or insulating wire before running ControlBear, so when is it safe to close ControlBear/unplug USB & what should you do after it?

It's safe to remove the USB/ close ControlBear at anytime when ControlBear isn't connecting/ connected to the device (i.e. when ControlBear says "Taking a sip" or when it is performing backup or restore).

It is also safe to remove the USB when ControlBear shows the message "Do wire trick" but if you unplug the USB now, then you should do the wire trick with the USB disconnected & then connect the USB, but don't remove the SD Card at this point.​

Why you don't get the JuopunutBear screen:

You don't see the JuopunutBear screen in the temp root method. It's as simple as that.​

Timing of the wire trick:

It is not 100% universal (especially the pause time). 1.5 sec is the ideal pause time, but this may need to be adjusted sometimes. Read ahead.

The video I made for JB S-OFF:

Available in HD! :)​

If your phone goes blank (powers off) before/after the second tap & stays that way, it is indicative of the pause time being too large or the contact being made for too long, due to which the phone powered off. Just press the power button ONCE to get the phone started again. If this happens every time you do the wiretrick, then you have a faulty SD Card; use a different one. If this doesn't get your phone on again, then read ahead.

Too may wire trick messages?

You must make a proper contact. Till you don't make contact, the ControlBear window will say:

Do not remove sdcard from phone

Do wire-trick now!! Look for instructions at http://unlimited.io/​

If you see more than 10-12 of these, it's an indication that you are not making proper contact. The tap must be short but it should make good contact but not more than ~0.6 sec.​

If your phone doesn't start:

Don't panic.

Make sure that ControlBear hasn't found your device yet.

If it hasn't, close the ControlBear window.

Unplug the USB cable.

Pull out your phone battery for a few seconds.

Re-insert the battery & power up the phone.

If it doesn't power up, then put in on charge for 6-7 hours.

If it powers up, then let it boot & then connect the USB cable and run ControlBear again. (it may give the S Off failed message without having to do the wire trick, just exit & re-run ControlBear)

If it still did not power up, then remove SIM, SD Card & Battery from the phone & charge it for another 6-7 hours. follow the previous point after you get the phone back on.

S-Off Failed:

Another frustrating situation is

S-Off failed. Still sober!​

The key to getting the wire trick right is not to keep repeating for perfect timing, it is to try to vary the pause time after each failed attempt, such that it perfectly suits your phone. So when you try again, try making small changes to the pause time (i.e. either reduce it slightly or increase it slightly). The pause time should, however, be in the range of 1.3-1.6 sec. Beyond 1.6 sec is not possible for non-unlocked phones.

Tired of trying to get it right? If you've made over 30-40 attempts, it's a good idea to use the Unlock method if your bootloader can be unlocked. Just restore your phone with CB (Check the troubleshooting points in the OP) & remove temp root. Unlock your bootloader via HTC Dev & go to this guide & follow instructions. (You'll need a different version of ControlBear if you do this. Get it from here.​

When to use a different SD Card:

Finally, a last suggestion, if your phone powers off & you get a pop up about "QHSUSB_DLOAD" drivers on the computer, then you need to follow the steps stated previously about what to do if the phone goes blank (powers off). You will then need to restore the current SD Card using following the instructions for ROM/Data recovery under troubleshooting

Before starting ControlBear again, you'll need to use a different SD Card. This one cannot be used for S-OFF again.

Then, Unzip all files from the controlbear zip that you downloaded to a new folder.​

What if my phone cannot boot properly to Android/recovery after JB?

If your bootloader is not unlocked, this is rare. Yet, something might have affected some partition of the phone. Try flashing a ROM/ reflashing the recovery (depending on which one isn't booting properly.

If that fails, your best bet is to flash the right RUU & then flash the jb_hboot.

If you are able to boot but still see only a black screen with a status bar, then you didn't remove temp root.​

My bootloader says *** LOCKED *** & S-OFF?

This is most likely because the jb_hboot.zip doesn't have your cid in the android-info.txt file.

In order to flash the JuopunutBear hboot, you'll need to add your cid to the android-info.txt file.

To get your cid, make sure your phone is in fastboot USB.

If you are in a black screen with htc in silver, that will work too.

Do this:

Open cmd (Start > Run > "cmd")

cd to your adb folder for example:

cd "c:\program files\android\platform-tools\"

Now, type:

fastboot getvar cid

Copy (Right-click, select mark, hold left click & drag to highlight the cid then press enter) the cid you get. Cid is 8 characters long. for example: HTC__001

Now, open jb_hboot.zip & double-click the android-info.txt file

Replace HTC__*** with your cid. Be careful not to alter the spacing.

Close the file, save changes to the text file & save changes to the zip when prompted

Now, cd to the controlbear folder in cmd

Tpye:

controlbear -i

Done!
