Well...my wife's transformer is incredibly slow and she is giving me permission finally to root it. However I have had difficulty doing so because the charging/interface port on the tablet has issues. A while ago the port stopped charging the tablet. We have multiple chargers for that tablet and nothing will charge it via that port. The only way she can charge it is by plugging it into the keyboard dock and charging the dock. Therefore when I try to plug the tablet into the computer so that I can forego the root process the computer will not recognize it.
So my question is.....can this tablet be rooted by downloading files to it and not need a tablet to PC interface? Or, can the tablet be plugged into the dock and interface with the PC somehow? I looked through all the rooting methods I could find and all of them required a tablet to PC interface.
Unfortunately you need a computer USB connection to root it. There was only 1 firmware (8.6.5.19) that could be rooted without a PC. In order to downgrade, you need a computer as well.
I have been able to root mine using the dock charging port. I just booted to APX mode (VOL UP and POWER).
I wrote a guide on how to root here: http://www.transformerforums.com/fo...t/31927-frederuco-s-guide-root-rom-tf101.html
If the dock is charging the tablet surely the issue must be with charger/cable ive had issues with tf101 cable before, mine would slow charge at rate that was bearly noticable, and the tablet didn't show a charging icon, but the cable did allow a data connection still. If infact it is your tf101 thats the issue root will be out of the question but i belive the stock kernel can be overclocked with an overclocking app which might help a bit.

One would think cause that is the most logical explanation. However, I have tried 3 cables (one the original and other 2 brand new ones) and 2 different OEM power supplies and one that I made which has the proper output ratings and none will charge the tablet. However, all of them will charge the dock. The only way to get the tablet to charge is by plugging into the dock. I know it uses the same port and I am clueless as to why one charges and the other doesn't on the same port. All I know is that is what is going on.
The only problem I ever had with flashing while docked was flashing Ubuntu. But I always flash while docked, so that shouldn't be an issue.
I just flashed back to stock, then re-rooted (wanted a TWRP backup of rooted stock) using the OEM cable via the dock charging port.
No issues here.

I've been having some trouble with my TF101. It started with the charger that simply stopped charging. Tried putting on the freezer and a bunch of other stuff but nothing helped. I've then tried to use a tool - Ai Charger - that changes the voltage of the PC's USB port so I could charge it just like the charger.
But the PC couldn't recognize the tablet as a USB device, probably because of no USB mass storage. So I decided to go back to stock to see if it helped. It didn't. And now I'm stuck with the TF101 using stock ICS and I desperately want to go back to Megatron 1.1.6, but I have no root, and no way to USB it into my computer to root it.
Any suggestions on how do I get root back?

I'm pretty sure the AI device thing does not trick the TF101 into charging. If you turn on USB debugging does it detect anything?

Absolutely nothing. It does charge the device at an unbelievably slow pace when it is turned off. Like, two entire days for a full recharge.

Have you try to use another cable?
I was there once, pulling all my white hair, everything solved after using new cable. Now I can go back and forth from various ICS and JB.

Yeah, I'm guessing this is really the issue. There was one time since the beginning of this post that my PC recognized the tablet and started installing the drivers for it. Guess I'm gonna order a new cable and test it. Thanks for the help, guys.
And to get root I recommend this: http://forum.xda-developers.com/showthread.php?t=1689193
It can root almost all TF101, in a very simple way
My TF-101 external interface is messed up. When I plug into my keyboard, the keyboard works, but USB and SD cards aren't recognized. When I try and connect directly to my PC (Linux or Windows) my transformer is not recognized. I tried to boot into apx mode, and my transformer will not do it.
I've tried switching MTP on and off, usb debug on and off--nothing.
I opened my transformer and switched out the physical interface port with my other working transformer, and it made no difference (i.e. it is not the physical transformer port).
any ideas or suggestions?
What ROM/firmware are you running?
Judging from your tests, it tells me there's 2 possibilities:
1. Software is creating the problem
2. The issue is deeper than the USB interface, could be the controller on the board or a number of other hardware issues.
Can you still boot in recovery? If so and if you're rooted, do a nandroid backup just in case. Also do a full backup of your data and copy over wifi using samba or airadb or ftp or etc. Then do a complete flash using easyflasher, get it back to stock. Check if the problem persists. If yes, then I'd assume it's something hardware. You could compare voltage at different test spots on the board.
Edit: I assume APX/transfers work while not docked?
The USB and SD cards are on a different circuit from POWER from the dock, as well as the physical KEYBOARD. I am pretty sure the touchpad is also on the USB/SD circuit, so I would bet that is not working.
Most likely this is an issue with that circuit/board on the dock.
As far as PC detection, I would try getting a new cable. I (and other) have had an issue where our tablets were NOT recognized by multiple PC's, but using the same cord did work to power the device to charge it from the Asus wall wart. My cable has been badly abused by about 12 trips around the world in the last 2 years.
Thanks but it's not the cable given that I have a second transformer working fine on it. I'm on a stock non-rooted build on this one. (The other working transformer is stock, rooted).
Perplexing. Keyboard works with other transformer, as well.

Just to lay out the symptoms: No connectivity with computer (Linux or WIndows) over USB when transformer is booted normally. Transformer does not come up in APX mode. I'm plugging directly into tablet with a known good cable. No hardware problem with connector (pins are good).
Running pure stock US 9.2.1.27 (ICS 4.0.3)
Can boot recovery, but have no good update to use. Anyone with a tutorial on how to "update" a downgrade to honeycomb using stock recovery and a microsd, I'm listening.
thanks,

You will need to use Wolf's Downgrade method to install an older recovery from the HC firmware you want to flash.
Since your computers don't recognize it, you cannot downgrade as you need ADB via USB working.
How do you know it is a good cable? My original cable works to charge just fine, but one or both of the data wires (pins 2&3) are not working so it is basically just a charging cable.
Got a new cable and computers can detect it.

Hello there
Ive got a problem. I wanted to Root my SL101 (Firmware 4.0.3 Android) with Peri or THe 1 Click Solution. But the original usb cable only charged my device when I plugged in to power socket. BUt USB on PC didnt work. PC never found device, didnt search for driver and no "BLing" for USB device plugged in. So I ordered a new usb cable (not original, cause asus sl101 already 3 years old). The new cable worked. USB found on PC. Data transfer worked. Charinging over power socket worked, but no charging when connected to pc. When I enabled USB Debugging, it said "Device removed" and then "device started". But there was no deivce seen on computer. No "internal storage". So there is no possibility to transfer data and Root won't start cause it doesnt find device. I installed all driver (ADB driver, also tried Asus Pc Suite), but it doesnt work. Is my device broken or is it because of the cables? Are there any working cables on internet with better quality and supporting USB Debugging? The non original cable is from vhbw.
Is this a common problem with Asus Sl101? I searched for related problems. SOmeone also had problems with Asus original cable. It also charged plugged in to power socket but not with PC and Pc never fund USB conection, never searched for drivers. He ordered a new cable (original, cause his case was years ago) and it worked.
Any ideas how to get it work? Its not really important to root it though, but I wanted to buy Titanium Backup so I can save my apps, and I need root for it. There are f course plenty other apps needing root. Any advices?
Not sure about the data transfer error apart from lack of drivers, but the PC will not charge the tablet while it is running - at least for the TF101 anyway, the only way to get the PC to charge it is to either turn it off while its plugged into the PC and leave it overnight for trickle charge, or I think also if the tablet is in sleep mode, it will also trickle charge - but you have to use the main charger to get a fast charge into it - PC will only trickle charge

First of all, thanks for answering. I tried it, but when I plug in USB, Asus SL101 turns on. I won't charge turned off. It turns on automatically when I plug in USB to charge. And when its turned on plugged in on PC USB, as I explained before, it won't charge.
Somene know where I can get a working cable? Maybe an original working one? Asus SL 101 is maybe 2 or 3 years old know. Shouldnt there be still original ones left in shops? Actually it doesnt have to be an original one. A working one is fine, too. (Working means for me: USB, Charging, USB Debugging). So anyone knows good stores/internet offers (amazon, ebay...) for sl101 cables? Cause I really dont know which one is a good one.
Plug it in to USB and then turn it off, you won't see it charging, it is a very very slow process when you charge from PC (If it works the same as the TF101) - leave it overnight plugged in and turned off
Sounds like your cable is working fine, you get a data connection with USB debugging - so data side of the cable works, and you get a charge when you plug it into the charger, so power side of it is working too
It's likely drivers stopping you using the media transfer mode
eBay would probably be your best bet if you want another one
asusparts.eu sell some stuff too - fits SL101
http://www.asusparts.eu/en/Asus-KIT-AC-TF101
Ya actually I didnt want to complain. The cable really works fine, but I cant root cause USB Debugging Mode is found by PC, but showing no storage icons on computer. So Root Software dont find device and no data transfer works while it is in debugging mode. Could it be because of my device? Actually it was from germany and the firmware also was DE. But for updates, I had to change it to WW code. Maybe its cause of firmware. I really dont know. Its strange cause for everyone it works, only for me it doesnt work. So original cable was to begin with not working on usb pc. So I hoped the fake one would work full. *sigh*
Thanks for the link. I searched for only the cable (on the given link) and I found it without adapter. But its a pity, Im in germany and if they send the cable to me, I have to pay 46$ for the cable. For US people its 25$ (cause they dont have to pay oversea sending costs). If its also not working, so it would be a problem.. even warranty is expensive (sending back ~20$).
Is there a way to downgrade SL101 from 4.0.3 to Firmware Version 3.2 without using USB Debugging and root?
Case closed, Watson (I always wanted to say that)
I found the error. The cable is working now and USB Debugging working, too. Root was successful. I opened device manager and deleted Asus Epad Sl101 driver and plugged sl101 in. So windows had to search for drivers and it installed the right drivers. I dont know why preinstalled ADB Drivers didnt work, but now everything works.
Thanks for your effort
Great, yea sounded like a driver problem, pleased you got it working :good:
Hello,
I recently flashed TWRP and CyanogenMod 13 on my Mi4. It was working quite well, I had some problems with the rotation sensor and some bugs in the software, but Quick Charge and also the Connection to the PC worked without problems.
Today when I was on my way home I was charging my Mi4 with a Qalcomm 2.0 Quick Charge Powerbank from Aukey (i have used it in the past on other phones, always worked great), but it seems that the USB cable was broken, it was charging very slowly and it also seemed to have a defective contact (the cable charged if i moved it around a bit, but in certain positions it wouldn't charge).
However, when i got home and plugged it in, I noticed that the phone also charged very slowly with the charger, so I thought that I would just flash MIUI back on the device to fix it, maybe it was a problem with Cyanogenmod. But that didn't work at all, the phone couldn't connect to the pc.
So, here's my problem: The PC can't detect the phone and it also seems, that the phone doesn't recognize, that its connected to a pc. Charging via the USB ist still working, but very slow. Also Quick Charging isn't working, it doesn't matter which charger or cable I use, it's always slow. When I connect the phone to the charger or the PC it takes like 5 seconds to recognize, that a cable is connected, then it starts (slow) charging.
The phone doesn't show up in the windows device manager at all (there are no unkown devices shown, the pc just doesn't react when you connect the phone). Also there is no message on the phone when you connect it (usually you can choose if you want the use your phone as a usb drive or just charge it). I also tried to activate MTP in the developer settings on the phone and turning USB Debugging On/Off, but it didn't help.
I managed to download a MIUI Rom from xiaomi.eu with the phone and installed it with TWRP, but it didn't help. So I think I actually broke the USB Port of my phone with a defective Micro USB Cable. The phone can still charge (very very slowly, no quick charge possible), but I can't connect it to the PC anymore. The pc also won't detect the phone when it's in fastboot mode.
I tried to look it up on the internet, but all I found were people with driver problems, and I don't think that I have a driver problem, because it seems like there is no connection between PC and Phone besides the charging.
Anyone knows something about this? Is it even possible to just break the data connection and the quick charging with a defective cable?

No, I didn't find a solution for the problem. Phone is still not working, I even ordered a new charging port, but I made a mistake and ordered one for the LTE version. I have the 3g version, so the new charging port didn't even work with my phone. I don't want to spend any more money on it, so I just gave up on fixing it.
Same problem, and I am also stucked in recovery for now, never will buy phone without SdCard now...
Somobody found solution?
So I've had my S7 for around two months now, and all of a sudden fast charging just stopped working. Thought, oh, must be using the wrong cable (have loads of them micro USB cables floating around)
Now I'm certain I'm using the official Samsung fast charge plug and cable that came with the phone, and still no fast charge. When I try to plug into my Windows 10 Desktop or Laptop I have a message that says the device can't be recognized
Phone has already been rooted and flashed with a custom rom. Didn't think that was the issue as it wouldn't even show the mounted storage in TWRP, or identify the phone in ODIN.
Now I've flashed back to the stock rom that I made a backup of when I had the phone, and I still have the same problem!! Can't access internal / external storage using the supplied USB cable and can't fast charge.
I'm thinking the USB port on the device is just knackard.. but really, I've looked after it so well I fail to see how this could happen, unless it's a common fault.
Might just get a wireless fast charger, but do you guys have anything else I can try before giving up on the USB connectivity?
Cheers
try to connect to a different pc, if same it means your usb connector is faulty
Sounds more like the cable is bad tbh, you won't get fast charge from a PC USB port, only from the Samsung charger
But if the device isn't recognised by the PC, and won't fast charge from the charger, the common thing between them is the cable
Possible it's the phone USB port, but more likely the cable is bad
Afaik certain cables can not fast charge either, so chances are the ones you have lying around that are not the official cable can not support it
Genuine Samsung USB cable is white with the USB port symbol on both ends and the phone end has two small ridges to grip when inserting and removing it, should help identify it
Yep I'm using the official cable and fast charger
I'm trying to fast charge via the fast charger and not USB. Only trying USB to access the internal / external storage.
Tried on my desktop and laptop and both have the same issue where my old HTC m8 connects without any issue.

To fast charge I've tried the original Samsung cable with the fast charge plug.
To connect to the PC I've used x3 different cables that all work with my HTC one m8. With all of them I get device not recognised. Already tried installing Samsung switch and reinstalling drivers which didn't work.

Does sound possible the phones USB port is faulty if you can't get any connection at all to the PC with multiple cables

Unfortunately not. Well it's been rooted and flashed so I guess not.
Ordered a wireless fast charger so hopefully that will see me through and WiFi network for file transfers.
I reckon the USB port will need replacing but I'm not really inclined to do that myself.
Just noticed you said you flashed back to stock using a backup you made
Have you tried stock using ODIN and 100% stock files, using CSC to reset?
My dad has a5 2016 with the same issue, and no warranty. I bought flex + connector , replaced it and still nothing. No fast charge ( it takes cca 4hrs to charge it fully ) and no usb connectivity. I gave up on that
@ClowsTyle
Any luck? I seen your recent post in another thread and it sounds like you tried to replace the USB but that didn't work.
I'm having the exact same issue now. Device suddenly stopped fast charging, Windows does not recognize it when plugged into PC. I ordered a new cable to double check and also tried on different computers. I also tried reinstalling drivers, but nothing has worked.
Hi my is doing the same thing no Fast charge and no pc connection, did anybody find out what happen with yours ?
You have to change power ic s535 for s7 edge.
When usb gets moisture power ic will damage.
I have same problem my phone charging 0-100 6hours but ı install notorious kernel and it takes 3 hours it is better than 6 hours
Same Issue
I've had the same issue for the past 3 weeks now and I've tried everything I know...
1. Tested cable and charger with another S7 and they work fine.
2. Factory Reset.
3. Changed the USB port chip.
4. Turned on "Low Battery Dump".
So far, the issue hasn't changed.
was this issue solved?
I´m having same issues whit my galaxy s7 active, I can not fast charge my phone no matter what cable I use, then noticed that evrytime I plug it to any computer it says the devicescan not be recognized, I´m about to buy a new charging port and install it, but I want to make shure this is not a software related issue.
I´ve tried several cables and several laptops/ pc´s
I´ve factory reseted my device and turned on low battery dump, wiped cache partition, and problem still there...
The charger could be faulty/damaged did you try a different charger?

Is the USB faulty?
