How to Downgrade BB5 SL3 Phones
 

Could someone tell me the correct way of Downgrading BB5 SL3 phone such as 5800, 5130 etc.

I have MX BOX and Cyclone which box is most suitable for downgrading?

Back up all first.
After back up erase & write flash then restore your back up.

I could not get the phone into Local or Test mode eventhough I flashd it with the latest firmware. Therefore I tick the New Downgrade radio button in the cyclone and select down version firmware and finally flashed. Cyclone tried to get a back up of RPL but due to enabling to get the test or local modes cyclone could not make a backup and I did continue without a backup

Cyclone said that failed applying backup and fleshing inturapted

Then i flashed with latest firmware which phone had at the first of all

Flashing compleated but phone now get contact service.

I buscheckd with MX BOX and got that,

SIMLOCK seems to be invalid
WD timer activated
SUPERDONGLE_KEY seems to be invalid
CMLA_KEY seems to be invalid
WMDRM_PD seems to be invalid
SIMLOCK_TEST Failed
SECURITY_TEST Passed!


This disaster happened to me finally

I know that its very important to backup everything before do risky things but some phones can not get to local or test modes even they are working phones.

BX BOX is veryyyy bad in getting Local and Test modes

Why??

I can get the same phone in to local and test modes with ufshwk micro with the same cable set.

I have HTI Orange Box

which mobile your ?


u need
blank_504KB_pmm and

ENO
after flashing and eraseing
mobile canot show local modes and test mode

use this files
your mobile come in local modes test mode..
then wirte backups

SIMLOCK_TEST Failed

This is a 5130 RM495
SL3
BB5

So if i did not have rpl backup ??

I could not make it could i?

yes you can't repair it only solution buy rpl

could you tell me where to by BB5 RPL ? Is there RPL service for BB5 ?
