•lvl 3 = 110 (was 100)
•lvl 2 = 100 (was 88)

29. How to put the apps on external SD card? (#2372)

1. You have to install App2SD;
2. For App2SD to see the external SD card you have to checkfrom options din storage/default write disk/external storage; (if you willcheck built-in then app2sd will see just the internal si built in storage).

See posts 2304, 2306, 2308, 2290,2294 from the Softpedia forum.

30. Resolving the lost IMEI (#816)

R: In case you lost your IMEi after an installation, and you use a writing soft to have the IMEI again, you have a problem. You don't know the second IMEI. On the box is just the IMEi from the fisrt SIM.

The idea is this: Both IMEI numbers are the same, except the last digits.

So if the first IMEI it ends with 19 (for example), to find out the last 2 digits for the second IMEI you have toad 1 at the penultimate digit and subtract 2 to the last digit, resulting 27:

1. IMEI 1 = 19
2. 1+1=2 and 9-2=7 2+7=9 < 10
3. IMEI 2= 27

If the penultimate digit form IMEI 1 is 9, it results 9+1=0 but you will add 1 on the digit before penultimate digit:

Example:

1. IMEI 1 = 299
2.IMEI 2 = 307

ATTENTION
If the last 2 resulting digits for IMEI 2, add up, are greater or equal with 10, then the last digit from IMEI 2 will be less with 1.

Example 1:
1. IMEI 1 = 50
2. 5+1=6 and 0-2=8
3. 6+8=14 >10 so the last digit is 8-1=7
4. IMEI 2= 67

Example 2:
1. IMEI 1 = 38
2. 3+1=4 and 8-2 = 6
3. 4+6=10 =10 so last digit is 6-1=5
4. IMEI 2 = 45.
