Firstly I muz say that there is nothing wrong with the theme itself.. the only difference is that the bamboo theme has a much bigger iconres.ezx (abt 1 MB)... the phone internal RAM(i tink shld be the /usr directory) can only accomodate up to 5 MB of info... this includes the themes, your sms, mms messages, etc... so if u install too many themes at 1 go.. the chances of failed installation is very high..cos the iconres in that directory is not completely deleted also even if u delete the theme manually, unless u used Yantz theme_uninstaller.lin or manul telent to clear off the "garbage".
Usually this problem happens if u have the fw version like R51_G_0F.
51.A1P, after installation, the installations showed a "failed installation", u go n set the theme in the theme changer, it will crash the phone as wat u have described! this is becos this firmware version does not suppt custom themes!
If u cant use the telent method suggested by Yantz cos u never set the phone to modem mode, u can try this hard reset method to see if it works:
1) Power Off phone
2) Press n hold the following 3 keys :
Volume lower key(side bottom left) +
Camera Key (side top right) +
Power on/off button (front bottom right)
3) U will see some sort like windows "Blue screen" or BSOD like appearing:
reset bp
endreset bp
.........
..................
start reflash code
4)
Note: u muz see the "start reflash code" before doing step 5, else keep repeating the same procedures till u see it
5) wait for 1 min, power off... restart...
6) Everything should be back to normal, u may still have ya contacts lists n messages intact.. u only lose the manual installed programs
7) Once u get to step 6, i suggest u do a syn with ya PC to "save" the contact lists....n then after that perform a master reset to get back to factory default, else the crash problem may come back.....
Btw, I have not tried this method b4, cos i never have crashing problems.
but this method can be tried without any harm if ya phone really cannot wotk due to the failed installation n activatin of custom themes...
If u try alot of times still cannot, i suggest u get it to the customer service to "flash" it....
Pls post a feedback if u r successful... thanks !!
Good Luck!
