Have You Killed Your Modbo or Cant flash Modbo Blue?
Have You Killed Your Modbo or Cant flash Modbo Blue? –
If you have killed you Modbo V1.1 or V1.2 attached is a 1_4MI firmware.
All you have to do to fix it is desolder the 8pin chip SAIFUN - 25F010 or SAIFUN 25F005. Reprogram with the f_ware attatched. Hope this helps someone...

Is this the normal 1.4 or a modified version ? Can you be more precise about the re-programming part ? Are you saying you can reprogram the main chip without the Saifun chip ? And then, do you just leave the Saifun chip off ?
South Africa. Repairs, chips etc.
What I am saying is that you can reprogram just the SAIFUN chip. Not the main chip. This has been a very useful discovery for me because I have just had a new batch of Modbo blues arrive and they are not flashable by disc. The code I have supplied is read directly from a successful flash by disc of a modbo1.1. I then took the saifun chip off. Read it in a ALL-11P3 programmer, saved the code and then used it to reprogram the new batch of modbo blue wich are protected internally from disc flahing. I unprotected the SA25F005 with the ALL-11P3 and then used the saved F-ware form the old modbo wich uses SAF25010 (not protected internally). The 1_4 f-ware I have supplied works fantastic and there is no alteration.
If you can get your hands on a programmer like the ALL11p3 then you can see the advantage of repaird bad flashes and flahing new modbo blu with 1_4 f-ware wich works a treat. If you have an smd rework station it is eay to remove and replace the SAIFUN chip.
Where did you get these blue modbo's at? Can you post a picture of one of them?
Got it from a China supplier.
Hi everyone. I am also working on putting the MI 1_5 full DVD+DL firmware onto the Modbo clones. As we all know, the Modbo dies if you try to flash with F-Ware 1_5. Stay tuned. I think I am very close to releasing this for all to enjoy
Hmm, we need some sort of flashing device to reprogram it huh?
Not if I strip the 1_5 F-Ware successfully. Cos someone could use it to make our own flash disc that won't kill Modbo.
the issue with 1.5 firmware is not the flashing, the modbo has no problems taking the firmware.
The issue is 1.5 has anti-clone protection. So the solution would be to disect the 1.5 firmware and figure out whats going on.
My guess is the protection is achieved by either using commands that the Modbo does not understand, or that it makes calls to the main chip's memory for some data required in a calculation.
I'll make up a purely fictional example for illustration:
On boot up we have a simply conditional statement, making a call to address ####. If the contents are xxxxxxx, then continue to boot as normal. If the contents are not the same, then simply do nothing (and the result is the system doesn't boot correctly)
Has anyone actually obtained the 1_5 code and tried to program the SAIFUN chip and then solder it to a Modbo? I guess I am wasting my time if someone has allready tried that. What I am saying is that I am very close to aquiring that 1_5 F-ware without the disc and separately programming the Saifun. I understand that the main chip on the clone is different to the main chip on the genuine MI. But is it still worth a try if no one has done what I am trying to do? Anyways... I am about 4 days away from knowing if my idea and teqniques will work
