How to Update Tx-Power with Magic Power v5.0

Nick Wenzel · Nov 17, 2016

Hi PapaTita,
I'm considering the mod for the P3 Standard. What are the potential risks of installation? And can it be reversed?
Many thanks.

There is always a risk in modding stuff that aren't supposed to be modded. My personal opinion in this case is that the risk aren't that high. Also there are lots of people that has done this, including myself, without any issues.

It can be reversed.

Beware though that you are potentially risking your warranty if you do this.

any modding done by accessing "backdoor" which may available on the first place. but when it goes wrong, it might close the backdoor itself.

in this case, mods are working via wifi. when something goes bad, we might no longer connect to the wifi it self. example, when we set the channel out of our PC/laptop channel range, so we can't do anything more. and this is just an example that might find some workout by using other PC/laptop. but in some other case, there almost 99,99% no way out.

another example is doing upgrade of PC's BIOS. there are stright requirement to be held carefully... once we make mistake, then the board is completely dead (bricked). unless some board which has 2nd BIOS containing backup, but they are realy rare only for highend (gaming/server) series. or we replace the phisical of the board's BIOS chip.

so, what is actually the real danger of modding? some people says it's reversable, when they know another way other than the first "backdoor" it self. and some other people says it is not reversible, because they don't have any other idea (yet) about another way other than the backdoor.

sorry for talking a bit out of topic.... [emoji16]

Did you find the difference on vsftpd.conf under 1.7.9 firmware?
/////////////////////////////////////////
local_root=/tmp

anonymous_enable=NO
local_enable=YES <---------No ???
write_enable=YES
local_umask=022
check_shell=NO

So how have DJI restricted FTP access? Is there any way to reverse it?

See post 691

Post 691 allows you get around the change DJI made. I'm asking if there's a way to reverse the change (i.e. so that you can browse all directories via FTP).

I don't have P3S but with help of a friend this is a range comparison using firmware 1.5.7 + Magic v5.1 and 1.7.9 + Magic v5.2 at:

- Same location
- Same day
- Stock antenna + windsurfer

1. FW 1.5.7 + Magic v5.1

2. FW 1.7.9 + Magic v5.2

3. FW 1.7.9 (No Magic)

Im using magic 5.1 on fw 1.5.7. Would like to go to magic 5.2 and 1.7.9. How would I do that? Use magic to go back to original settings before upgrade/ etc

Yes. Revert back to stock, upgrade fw 1.7.9 through DJI GO and mod again with v5.2
