TIPS TO NOTE TO AVOID DEAD-LOOP-PRELOADER AFTER FLASHING OR DOING SOFTWARE UPGRADE ON XBOX-DEVICES

STEPS TO TAKE TO AVOID HAVING ERRORS AFTER

UPDATING OR FLASHING XBO DEVICES

Make a backup of necessary device partition before the flashing of new firmwares, the needed file that are to be backup include:- 

Uboot, Secro, seccfg, Booting, Preloader, Protect F, Protect S, and all the file should be backed up with the exception of the system and Userdata and cache file. Make it safer so the device could be restored if the internal software gets sundered hence the backup could be done with any software that could backup file on an MTK Devices in scatter format.

Below are The necessary tips which would help an Engineer to have a very positive Result updating XBO Devices:

Make a backup of the preloader partition make sure to know the boot version of the device as flashing a wrong firmware may cause to the device to be hardbricked and can be restored only by test point method.ie RX and TX GND 

Before the flashing of XBO devices for example, XBO V3+ which has 2 different boot version: i.e MT6572:- Kitkat Android Version and MT6580 which is Lollipop Android and boot version hence boot versions are completely different but they are made for the Model of XBO devices. Avoid Flashing An XBO device with a ROM that backed up in(BIN) that is been formatted, because it would leave the device with low battery causes undue stress on the devices “BootLoader” hence the device could be dead at the end of the operation.

How to prevent XBO devices and some Infinix Clone devices from having BootLoops

a. Make sure to power down your XBO devices in a situation whereby the battery falls below (10 %)     percent.

b. Do not let the device power down by itself because it would lead to a bootloop at the end which would reload the new firmware on the device.

c. Avoid installing unwanted apps on the device which may resulting in dullness or hanging occasionally.
