Ok at the end I could update the t9 + with the Sdcard method but now this appears

Here the kernel log again

Topic: T9+'s Chain/Card Problem (Read 259 times)
This is a well-known issue for t9+ miner here in the forum and I don't see any issue on kernel logs except for err_nonce.
There is a thread here that same issue as yours and according to OP he solves his issue by changing the house wiring.
Take a look at this post here Antminer T9+ Low Hashrate on chains
I have an original power supplu APw3++ from bitmain, does not affect any hardware or psu in addition to more power consumption? that is to say, the psu will support that capacity?
here the kernel log

are you on 110-120 volt or 220-220 volt? for APw3++ on the former the output would be about 1200w so it's a NO , on the second the output would be 1600w so it's a yes.
so if you plugging it into a 110-120 v, don't even try it. unless you going to underlclcok your miner.

It seems a hardware issue and maybe some capacitor or resistor is missing from the hashboard. Try to compare the other hashboard and find the missing capacitor and resistor.
Have you tried the microSD card flashing? or they called it program recovery?
If not try this one and maybe solves your issue. Follow the guide from here T9+ Control Board Program Recovery
Why not, try the overclocking method from here https://bitcointalksearch.org/topic/how-to-overclock-your-s9t9t9r4-to-18ths-free-4425212 to increase the hashrate but expect for power consumption to be increased.

Well I tried with a different psu and the same, 9.5th and with the update of the firmware, I downloaded the firmware from the antminer's website
sadly, this is now very likely a failing hashboard, and there is nothing you can do about it unless if you it's still under warranty, then open a support ticked on bitmain's website.

... or perhaps just switching the power cables?
yes this will do.
2- a falling PSU
solution : try a different PSU

If it is a PSU issue, could it be diagnosed by disconnecting the other boards, or perhaps just switching the power cables?
unfornated totaly true ....
too bad, well on my shitty D3s sometimes increasing the volume and/or lowering the frequency helps, but usually when a board starts to act funny this way, it's only a matter of sometime before you lose hope and send it to the garage to sit next side the other wasted bad boards.
Hi, I can answer dessuit with certainty that the problem does not come from the pic, so my tutor will serivra strictly nothing unfortunately ...
I just think the hashboard is defective, I have the same problem, with also, it does not support that I used 600mhz maximum, beyond, it's the same problem ...

there are a few possible causes. will list them from most likely to least likely
1- the board is dead ( could be fixable but chances are slim)
solutions :
this could be a hex related issue, can be fixed using this great guide > https://bitcointalksearch.org/topic/repair-a-t9-after-a-bad-firmware-lost-chain-5032987
2- a falling PSU
solution : try a different PSU
regarding the error message you get upon flashing the firmware, looks like the firmware is bad, try using a different one, also make sure you using the T9+ and not just T9 firmware, also a hard reset could solve your issue.
* posting the kernel log will help troubleshoot your problem

Hey! I have a T9+ and I've mining for around of 4 or 5 month with 10.5 th/s and now i'm mining with 9 th/s. The Chain/card number 12 went to 0, I Reboot it a couple time and It's get back to 10.5 th but after 30 minutes It's gets back to 9th/s again. I really don't know what to do. I need help..
