IOS Recovery via XMODEM / ws-c2960G-48L

Cisco IOS Recovery via XMODEM / ws-c2960G-48TC-L
ICND2 - CCNA Preparations


When refurbishsing 2010 Cisco Catalyst WS-C2960G with new IOS and fan, after reload i get memory allocation error and stayed in Switch rommon.

Access:
- via console Serial-to-RJ45 only
- just few commands working
- image corrupted on flash:

Switch :

during IOS update one of the switches stayed down


















sudo apt-get install lrzsz screen
sudo screen /dev/ttyUSB0 9600

dir
dir flash:
set
set BAUD 115200

Ctrl+C

sudo screen /dev/ttyUSB0 115200

copy xmodem: flash:c2960-lanbasek9-mz.122-55.SE10.bin

Ctrl + A
:
exec !! sx /cesta_k_bin-file/c2960-lanbasek9-mz.122-55.SE10.bin

...and IOS image was there OK ;)

So i enabled routing with commands below:
sdm prefer lanbase-routing
ip routing

and L3 switch is working good

iPhone 4 (GSM) - 7.1.2 iCloud bypass tethered

(Baseband 04.12.09) activated with iTunes (from Win+Linux)

 Appz needed: 

iphone3.1 ... restore.IPSW (restore image)
SSH RAM Disk Tool
WINScp + Putty (or similar)
Newlibmobiledevice - (Win + Linux as well )
-- see the link .RAR5 on the end - no ads w/ complete tools

-- all was done from ThinClient Ubuntu which runs VM with Win7 ;)

How to bypass iCloud Activation on iPhone 4 7.1.2

- take out simCard!
- if not working - i forget something :D
- first restore to IPSW restore (iREB + itunes with shift)
- then from DFU - restore newest iOS (yes, 2nd restore works:)
- check the pictures below for some explanatory details








1. Device into DFU from iREB (only first time - limera1n)
2. Start SSH RAM Disk Tool and let it run (restart w/new DFU wrks better)
3. if going to Recovery - return back to DFU normally (power+home ...)
4. root + pass with port 2022 in green seen in Java console

5. edit /bin/mount.sh - mount_hfs rw /dev/disk0s1s1 1 0 (change ro to rw)
6. ./mount.sh
6. cd mnt1/Applications/ and rename setup.app to setup.app.old

7.  reboot

8. kick out from recovery -- > back to DFU
9. copy files from zip into directories:
-- cd mnt2/root/Library -- copy Caches + Lockdown folders from zip
-- in Lockdown place .pem files
-- cd mnt1/usr/libexec -- copy lockdownd file

10. reboot

11. ideviceinfo.exe (drag to cmd) - if FactoryActivated -- DONE!

12. go into iTunes and voila! >> NEW iPhone :)

12.5 -- if still not, activate FindMyIphone, activate Lost state, Erase and restore device -- than you will get lucky finally :F
-- really sorry lads, was playing with more iOSes and get lost in it / just don't put in the sim card until it shows up New iPhone in iTunes..


13. use Pangu 1.2 jailbrake - you have activated device now - but not needed, already having root write access to mnt1 and mnt2 ;) 

edit: Dunno if you need to restore twice - i had to...
