ROOT for AT&T Impulse 4G (Huawei u8800-51)
NOTE: I take no credit for SuperOneClick, or the actual guide. I simply found it, simplified it, and reposed here. Thanks goes to CLShortFuse for SuperOneClick, and all the members at XDA-Developers, specifically in the Huawei Ideos x5 forum.
Also, I am not responsible for any bricked devices, loss of data, zombie infections, Rage fits, or thermonuclear warfare caused by this guide. Oh, and also, if you succeed, your warranty is now void. PLEASE follow the instructions to a T.
This guide is for Windows PCs. I don't have any guide for Linux or Mac, sorry.
This guide will teach you how to root and install ClockWorkMod Recovery your AT&T Impulse 4G, also known as the Huawei Impulse 4G.
Put the device in ADB mode (Settings\Applications\Development\check USB Debugging)
Plug device into computer and let the drivers install.
to make sure the ADB driver installed (Right click "Computer" and click Manage, and click Device Manager) If 'Ideos' is in 'Other Devices', you will need to start at Step 2. If 'Android Composite ADB Interface' shows up in 'Android Phone', you are good to go to Step 3)
STEP 2 (Ideos in Other Devices)
When the device was plugged in, 'CD Drive (E:\) Mobile Partner' should have popped up for AutoPlay. If it did not, check 'Computer' to see if it has. If it hasn't, unplug the device and plug it back in. Once it shows up, go back into Device Manager from Step 1 and right click 'Ideos' in 'Other Devices' and select 'Update Driver'. Click on Install Driver Manually instead of Searh Online and browse to E:\drivers. This will install the ADB drivers needed to root.
STEP 3 (ADB Drivers Installed, now to root)
Now that your device has ADB drivers installed and working, download SuperOneClick v2.1 from http://forum.xda-developers.com/attachment.php?attachmentid=674200&d=1312258565
Extract all the files into a folder, and run SuperOneClick with Admin permissions (right click SuperOneClick, select Run as Administrator)
After SuperOneClick opens, simply click the 'Root' button on the top.
NOTE: It may freeze up a few times, as if it stopped responding. That is normal.
As it goes through its process, it will eventually stop and tell you 'busybox is not installed. Install?' Hit yes, and yes to all the other prompts. At the end, it will tell you that your device is now rooted. TA-DAAAAA. Reboot your device and the root is complete.
STEP 4 (CWM Time)
Download CWM here
Turn the device off, and press and hold Volume Up, Down and Power buttons simultaneously. The AT&T logo will pop up, and then a pink-purple screen will pop up over it. Plug the device into your computer and let the drivers install. A popup may tell you some drivers didn't install, that's ok. A single, unnamed Removable Storage device will come up; open it. Take the 'recovery.img' file in there and rename it to 'recovery-backup.img', then copy the recovery-clockwork-18.104.22.168-u8800.img' to the storage device. Rename it to 'recovery.img'.
IMPORTANT: Make sure to 'Safely Remove Device' before unplugging!
After unplugging, remove the battery and reinsert it, and hold Volume Up and Power buttons to boot into CWM.
There you have it, Root and CWM. I've begun toying around with ROMs, I will try to port CM7.1 to this device, along with a customized, clean version of the stock ROM. Enjoy!
