Use QR Code to gain Wifi Access

,

To get WifiWifi access by use of common QR CodeQR Code scanning apps, you have to QR encode the string

WIFI:S:MySSID;T:WPA2;P:MyPassword;;

which can be generated with the open source tool qrencode: 

qrencode -t PNG -s 12 -l L -o MyNetwork.png 'WIFI:S:MySSID;T:WPA;P:MyPassword;;'

WIFI:S:MySSID;T:WPA;P:MyPassword;;Apart from replacing MySSID and MyPassword by the right values for your network, you might need to replace WPA by WEP. I was told, a WPA2 might work as well, but WPA seems to be generic for both WPA and WPA2.

For a hidden network, a H:true is expecte as a last value, seperated by another ; and finished by a pair of them. In case of no password (no encryption), just omit the respective tags completely1). 

qrencode -t ANSIUTF8 -l L 'WIFI:S:MySSID;T:WPA;P:MyPassword;;'

Install TWRP 3.0.2 unofficial on Wileyfox Swift

Some time ago, I found an unofficial build of TWRPTWRP for the Wileyfox SwiftWileyfox Swift (crackling): TWRP_3.0.2-0_crackling_20160524.zip

For some reason, twrp-3.2.1-0-crackling.img from https://dl.twrp.me/crackling/ did not work for me2)

Steps done:

  1. Enable developer options/tools on phone
  2. Enable adb on phone
  3. Enable oem unlock on phone
  4. Extract recovery.img from TWRP_3.0.2-0_crackling_20160524.zip
  5. Boot Wileyfox Swift into fastboot
  6. Connect by USB
  7. Run 
    fastboot oem unlock
fastboot -i 0x2970 oem unlock-go
fastboot oem unlock-go

    on connected computer

  8. Run 
    fastboot flash recovery recovery.img

    on connected computer

  9. Reboot by command 
    fastboot boot recovery.img

    on connected computer3)

  10. Reboot or shutdown from TWRP Menu

Transfer system from one Wileyfox Swift to another with TWRP

This is a guide to transfer an Android system to a new hardware of the same type in case the old hardware is somewhat broken, but the system ist still running.
:!:This will not work as described to transfer the system to different hardware.:!:

Obviously, TWRP saves backups into a phone specific subdirectory and offers restores only for backups found in the appropriate subdirectory
TWRP does not backup the data of your “internal” (emulated) SD-Card
  1. Install TWRP on both systems (see above)
  2. Put old phone into flight mode to avoid sync operations during backup and restore
  3. Boot old phone into recovery mode
  4. Check time and timezone, select correct timezone eventually
  5. :!: Connect computer via USB and backup all data from internal storage to computer by mtp:!:
  6. Select “Backup”
  7. Select storage “MicroSD”
  8. Select partitions for backup
    • System
    • Data
    • Boot
  9. Start Backup
  10. After backup finished, shutdown old phone by choosing Power off from the Reboot Menu
  11. Move all SIM cards and the SD card from old phone to new one4)
  12. Boot new phone directly into recovery mode by pressing Volume down and Power, let go after approx. 5 seconds.
  13. Check time and timezone, select correct timezone eventually
  14. Select Terminal from TWRP menu
    or
    Connect to computer by USB and run adb shell
  15. Set current time by running
    date -s YYYYMMDDHHMM00

    on phone

  16. Do a dummy backup of some small partition (e.g. boot) to get TWRP subdirectory name of new phone
  17. Find new subdirectory either in /sdcard/TWRP/BACKUP or in /sdcard1/TWRP/BACKUP
  18. Rename
    /sdcard1/TWRP/BACKUP/<old name>
    to
    /sdcard1/TWRP/BACKUP/<new name>
  19. Select Wipe → Advanced Wipe
  20. Select5)
    • Dalvik / ART Cache
    • System
    • Data
    • Internal Storage
    • Cache
  21. Start Wiping by Swipe to Wipe
  22. Select Restore
  23. Select storage “MicroSD”
  24. Select most recent backup
  25. Select partitions to be restored:
    • System
    • Data
    • Boot
  26. Wait for restore to finish
  27. :!: Connect computer via USB and restore all data to internal storage from computer by mtp:!:
  28. Reboot into System via the Reboot menu.
  29. Connect to computer by USB
  30. On connected computer run6)
    adb shell date YYYYMMDD.HHMM00
  31. Reboot new phone
  32. Check date and time on new phone
  33. Have fun!
I recommend not to go online with the existing system on the old phone to avoid sync mischief. Factory reset the old phone as soon as you are confident, that the transfer worked well.

meaning no ;T:…;P… at all
2)
Flashing was possible, but fastboot boot <imgfile> gave an error and forcing boot into recovery by pressing Power and Volume down did stall on “Wileyfox” screen
3)
If you boot reboot into system first, the recovery image will be overwritten by the factory default
4)
You might want to do a image backup of the SD card befor exposing it to the recovered system
5)
should be all but MicroSD
6)
Yes, this ist different from the syntax above
