Error: Failed to read REG=0x80010008
Error: Failed to read REG=0x84010008
Error: Failed to read REG=0x80001008


Reason:
Bad Flash IC or Bad Cable


Solution:
1. Can try to change cable, try with slower baudrate and try few times.
2. Rehot the flash IC and try again. if still not then need replace flash IC/

@

Problem Description:
Flashing stops at different percentage everytime. Means first try it stop at 30%, next time it stop at 35%, then 10% and so and so.


Reason:
This can be due to:
1. Bad Flash Chip
2. Low power to handset
3. Bad data inside Flash Chip


Solution:
First i suggest to try with slow baudrate, try flash with slow baudrate. if this not success then better erase the complete flash chip and then try again. This should sure help if its not a hardware fault.
If it still not helps, means can be hardware problem too, in this case you can reflow the Flash IC or replace if necessary.

Problem Description:

Reason:
Unsupported Boot type


Solution:
You need to use supported boot type for this CPU ID. Just select "Boot 3.848" and it should work ok.

@

Problem Description:
"SPD USB TO SERIAL NOT FOUND"


Reason:
The drivers are not installed for SpreadTrum USB communication


Solution:
You need to install the USB drivers for SpreadTrum. when UCT box has finished finding the pinouts for spreadturm handset, it will ask for SPD drivers, these drivers can be found inside folder: "C:\UCT\UCT\SpreadTrum_USB_Drivers\" just need to install them and then UCT can start working your handset.

If in case the computer not asks for any drivers after pinfinding, then you need to un-install the bad drivers from your device manager and then again re-install the supplied drivers.

@

Problem Description:
"Failed to format Flash"


Reason:
Cannot format the flash for older type handsets, cause they not support new boot type.


Solution:
Just try different boot types and it should be ok. Some boot can work for some handsets. This is why it is not important that the latest boot will always work for all handsets. it can be also that only old boot type will work for some particular handsets.

@

Problem Description:
Error "Project ID not found" while connecting the handset


Reason:
UCT Software is not able to find the project id inside the handset flash, project id is the version of the firmware. This can be cause of wrong boot selection, wrong memory type selection or can be due to empty flash chip or hardware fault.


Solution:
to solve this, first try with different boot type and mode type, try all boot and also try with "NAND" memeory type as well. if still not works, then flash the handset with good flash file. if not able to flash, means bad flash chip, try reflow or replace.

@

Problem Description:
Spreadturm handsets show "Failed to RXD"


Reason:
This error can be cause of many problems. can be cause of wrong connectivily, bad cable, wrong boot type


Solution:
Select "6600L-USB" or "6600L-USB" in options and try again

@

Problem Description:
Error: Unsaft EFS Address, Please input the right format address and try again.
Failed to auto format.


Reason:
UCT Software is not able to recognise the flash addresses inside handset


Solution:
Try to do "Reset", If this not helps then only way to fix this is by flashing handset with correct flash file, if u dont have a flash file then u need to arrange a similar handset, read the flash from it and then flash it to your faulty handset.

@

Problem Description:
Read Info, Read Flash working fine for SPD handset, but format anf write flash not working properly.


Reason:
you are not sellecting the correct option type according to cpu id and flash id.


Solution:
Make readInfo of the handset, here in information you will see the CPU type and the flash type of the handset, for eg. CPU: 6600xxxxxxxxx Flash: NOR.
Now in this case, you need to select the option "6600L-USB" and then proceed.

Means it is very important to select the correct options, otherwise format, write flash will not work properly. for details, better read complete guide for SpreadTrum phones.

You need to look for the Full flash file of this handset and flash to it, If u dont find a flash file in that case you need to look for a working handset and read flash from it, then flash it to your dead handset.

Problem Description:
Get error "Invalid IMEI" when trying to repair IMEI for some MTK handsets


Reason:
Some handsets, mostly of CPU 6235 and 6253 have this problem after format. After format cannot write IMEI and show error Invalid IMEI


Solution:
To solve this you need to flash the handset. There is no other way to solve this problem for now.

But you can avoid this error by taking NV data backup before formatting the handset. Just select NV Editor and take full backup of handset before formatting. After format, write NV data back to handset and then fix IMEI.
