ios_examiner.py - UnicodeEncodeError - 'ascii' codec can't encode character u'\u2019' #70

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
1. Successfully uploading custom ramdisk to device using the following:

./redsn0w_mac_0.9.12b2/redsn0w.app/Contents/MacOS/redsn0w -i 
IOS5_IPSW_FOR_YOUR_DEVICE -r myramdisk.dmg -k kernelcache.release.n88.patched 
-a "-v rd=md0 nand-disable=1"

2. Attempting to execute the ios_examiner.py script using the following:

python python_scripts/ios_examiner.py

What is the expected output? What do you see instead?

Expecting to see ios_examiner command prompt ((iPhone4-data) /) and seeing 
instead the following:

What version of the product are you using? On what operating system?

Utilizing the most recent version of the tools via hg pull && hg update running 
on OS X 10.7.4 (genuine Mac hardware, not virtualized environment).

Please provide any additional information below.

Was able to successfully run ios_examiner.py roughly a week ago without issue, 
the only changes to the 3GS device was the implementation of a passcode; have 
been attempting to brute force passcode.

Additionally I have built a new custom ramdisk and kernel utilizing the 
steps/process outlined in the wiki 
(http://code.google.com/p/iphone-dataprotection/wiki/README) and continue to 
experience the same outcome:

hg clone https://code.google.com/p/iphone-dataprotection/ 
cd iphone-dataprotection

make -C img3fs/

curl -O -L 
https://sites.google.com/a/iphone-dev.com/files/home/redsn0w_mac_0.9.12b2.zip
unzip redsn0w_mac_0.9.12b2.zip
cp redsn0w_mac_0.9.12b2/redsn0w.app/Contents/MacOS/Keys.plist .

python python_scripts/kernel_patcher.py IOS5_IPSW_FOR_YOUR_DEVICE

sh ./make_ramdisk_n88ap.sh

./redsn0w_mac_0.9.12b2/redsn0w.app/Contents/MacOS/redsn0w -i

Try changing this line in ios_examiner.py
http://code.google.com/p/iphone-dataprotection/source/browse/python_scripts/ios_
examiner.py#105
from
self.prompt = "(%s-%s) %s " % (self.deviceName, self.volname, self.curdir)
to
self.prompt = "(%s-%s) %s " % (self.deviceName.encode("utf-8"), self.volname, 
self.curdir)

the tools currently fail when printing unicode strings with non ascii 
characters, i still have to find a proper fix for this.

Hello,

Applying the stated modification to the ios_examiner.py script has resolved 
this issue, I am again able to upload the custom ramdisk to the target device 
and utilize the script.

Thank you for your prompt reply and resolution to this issue.

Hi, may I just add that a similar patch is needer for backup_tool.py as well.
I have 2 device backups on my PC, one is parsed fine with backup_tool, but 
here's the output for the second:
