Watch Dog Definition

Watchdog stored in UEM, first used for controlling the system power-on and power-down. Both are used to block IMEI security and storage, the Watchdog will control the IMEI in UEM ROM with the IMEI stored in the IC flash, if there is a difference between the IMEI in UEM IMEI and IMEI in Flash then the Watchdog will provide the Shutdown command in 13detik time. Example watchdog could occur if the UPP who recognize the IMEI of sync as below:UEM IMEI: 35153200064744IC Flash IMEI: 35153200147706
* FLASH memory for the IMEI in UEM UEM Inside there is a place used for storing data and Tuning Values ​​IMEI. IMEI data storage properties in UEM is OTP (One Time Programming) where the IMEI data can be written only once and can not be removed or replaced, therefore UEM used or has ever entered the IMEI number can not be used to other phones, except where IC IMEI in Flash can be equated back to the UEM IMEI itself. The process of returning the IMEI mensikronkan called Calculate RPL. Of course there is the IMEI flash IC that can be written back.If IMEI in UEM UEM problematic or corrupt then it can not be used or can not be repaired anymore! UEM IMEI is corrupt can easily be identified if we do the info on the flasher box and stated: UEM IMEI: 351p32e% 064 724 <<IMEI in UEM is no longer display the numerical data! There is no any solution other than replacing it with anew. In the above case nokia phone will usually display the IMEI ????????? when we type the following code: * # 06 # <where the IMEI that is on UEM IMEI is different than it should, although there is only one number was different. This causes the phone can not accept sim cards (GSM) and will die automatically in a few seconds.WD BB5 reply in terms more familiar with Superdongle key. so if there BB5 SD yg watchdog corrupt so well, auto restart every few minutes. gampangannya wd be interpreted as a time bomb .. dct4/wd2 if only the range of 40 seconds dah barking his alias ****** explode om, hehe .. (I wrote this term) BB5 rather lengthy reply in the range 3-5 minutes, but in principle the same aja ..wd cause is a corrupt RPL.
for the case of the WD what hars done depends on where the source of the damage, if imei diuem yah yg dah walopun calculate RPL remains an injectable solution UEM wd wrote his will in the new locker injected both UEM and flash ic (and data1 data2)kecuai if the source of the flash ic aja corrupt, and injecting enough ask2rpl/calculate data1 (ic flash) dah wrong.
specific areas that store BB5 RPL not only in Rap, but also in nandflash. who can make beautiful BB5 RPL 123 456 ... the cause of data on nandflash tereset / kehapus. solution to this problem just re-write rpl well if there is data backupx, kalo beli deh yah ndak rplx. of the process via a read ask first (when readask who read the master data that are on Rap)
