[Q] Hisense Sero 7 Pro APX - Hisense Sero 7 Pro Questions & Answers

Hello, another user posted about a similar problem some time ago but did not get a response. The tablet does not respond to any button combination. When I plug the tablet in to the PC, it comes up as an APX device and the Asus Transformer Prime APX Interface drivers can be loaded. I've made sure my charger is working and have tried charging it overnight and also charged via PC. Can anyone please help? Thank you.

[Q] Transformer without USB with 8.6.6.9-20110804

Hello! I've a problem with my Asus Transformer (wifi version)
Today I tried to connect it to the PC with the USB cable and nothing happened: no charging, no usb detection on PC. Can you help me?
I think the cable is ok because I can charge the pad with the cable and the AC. I restored the tablet to factory defaults 3 weeks ago, after updating to 3.2. After that I sent the tablet to ASUS for warranty because a problem I had with the AC. They returned me the same tablet, cable and AC with a "Test ok" message, so I think they made no modification.
But today I've listened that a new firmware versions is landed, the 8.6.5.9. I looked at mine and I have a new one, 8.6.6.9!! I don't know if it was the update I made at first days of August.
The thing is that now I can't connect the pad to the PC. ¿Maybe is for the firmware version? ¿Someone with the same problem?
Thx
I'm not sure its firmware. Sounds to me like a bad usb connection. Can you verify all the pins are in place in your device?
Yes, I think the pin's are all ok, I can't see nothing bad there. It can be a problem with the firmware? Is it normal this 8.6.6.9-20110804? I read that people now have the 8.6.5.9-20110816

P7500 (WiFi/3G) doesn't charge, instead goes into MTP mode when plugged in!

I don't know if anybody else has had this problem before, but I hope there is somebody out there who can help me with my problem.
Basically, until a few days ago, my Galaxy Tab 10.1 was working fine until I did a reinstall from a backup as I was having a problem with the device due to it running sluggishly slow and crashing every so often.
Now, for some weird reason, the device won't charge at all when the USB cable is plugged into the official USB AC Adaptor and instead all I get is the "MTP Initialization" message that somebody would usually get when connecting the Tab 10.1 to a PC or Laptop.
It seems to charge when hooked up to a laptop very slowly but that's about it.
If there's anybody out there who can help me fix this problem, it would be most appreciated at all (to be honest, I can't wait until I go back to university in September and I can sell this POS and buy a 64GB Transformer Pad Infinity instead!)
EDIT: I've tried another cable and now it's saying that it's MTP-Connected instead of not MTP-Connecting at all!
Bump as I have a feeling that this isn't a one-off problem and that it's affecting a lot of other Tab 10.1's as well...
Never had that issue.
Are you sure your cable is ok?
Having exactly the same problem, no idea how to fix it at all. Looks like it's faulty usb port, because sometimes my laptop 'recognize' the tablet, but it's very rare (don't really know what does it depend on). I'm afraid sending the tablet to service is the only solution .
Try a different charger, different cable and check the port for debris
Sent from my GT-P7500 using xda app-developers app
I've checked the port and there's no debris in it, I've checked the new cable that I've bought and it's already worn through from the look of things at the end with the plug that connects to the device itself.

TF201 and PC will not connect

Greetings!
So, recently, my Transformer Prime stopped being able to connect to my PC. When plugged in, the Prime does show that it is receiving current on the cable, as the charging symbol shows up, but that is all. Windows shows no indication that the Prime is plugged in. This includes looking in Disk Management and in Device Manager. Nothing. Oh, and USB debugging on the Prime is turned on.
I have tried two different cables (both of which will definitely charge the unit), and 3 different PCs, all with no change. Additionally, there is no visible damage at all to the port.
I even ROM'ed it (after the problem started) with Cyanogen10 and nothing changed. Finally, I tried it with the dock, and while the dock works fine when they are coupled, if I plug the dock into a PC, still nothing.
I am sort of out of ideas. Anyone else have any?
Thanks!
Jonathan

There is another thread with a discussion on this. Perhaps it will help. Read through the posts to see any trouble shooting suggested, but I'm guessing your USB port is dead and will need to send the tablet back RMA to get it fixed - sorry to say.
See the thread here: http://forum.xda-developers.com/showthread.php?t=1624175
I had the same issue, and unfortunately soft bricked my prime while trying to see if different ROM's would fix the issue. the soft brick would have been recoverable if my prime would connect to my PC, but it didn't so I ended up paying Asus to repair the unit.
If none of the troubleshooting works, I'd flash back to a stock ROM and then send it in. mine would only boot into CWM so once they saw that, they figured that was the problem and charged me for the repair. I had seen a couple of people say that even though they were unlocked, the prime was fixed for free since they were able to boot up into the rom.

Can I ask how much they charged you to fix it? I'm about to send mine in for RMA, but have a cracked screen from a drop. USB worked for weeks after the screen crack, but I'm concerned they will say it broke due to my neglect. (Basically I don't want to spend too much to fix it with a broken screen). If I can get the USB working again, I'll consider spending some cash to fix the screen - but to pay for both I'd be better to just but a new tablet.
Never mind, I see you already answered me on a different post. $232.

TF700T Device root USB problem

Hello everyone, thank you for your attention.
As you already know I got TF700t (with docking keyboard) and everyone knows that this device is slow if it's not rooted. So the problem is that my usb cable broke and I first bought cheap chinese cable but when I connected it to the pc something happend. It was working fine just to unlock my device. But now when I try to connect it to the PC , the only thing that is happening is tf700t display turns ON. So I went to the shop and bought better cable but it's the same thing. And now I can't root my tablet. I tried with APK roots but they don't work on my tablet. So if you can help me somehow.
Thank you !
