I have been lurking in the shadows of this forum and it has helped me out alot so far. I finally registered after developing a bug or hardware problem (not sure which) with the original FW (rc33) that is preventing me from rooting my phone. Its with my QWERTY keyboard. It seems the entire top two rows are now activating more than one key stroke when i only press one, ie. press "e" and it comes up "3e". This really sucks when i get to the part of the rooting process to type "telenetd" before launching telenet. I have tried every combination i can think of to fix, but i am at a loss.
So, my question to all who can assist, is there an alternative way to root my phone other than the common way i find on all the forums? Anyway to do this thru the computer or anything? My computer uses windows vista. My phone has a non-rooted rc 29 (i did get that far in the process. i downgraded from rc33, got the recovery img on the root of my sdcard, along with the update.zip file. i also installed telenet from the apps store). I am ready for the next step is there is one for my situation.
I don't care how difficult or how many steps are involved, i just want to root my phone. Am i screwed or do i just wait for the official g1-1.5 and live with that version?

P.S. please don't tell me to turn it in for servicing. I am currently located in the country of Bahrain and that isn't an option for me for about another year. yes i am in the military and kinda stuck. Thank you for any and all support you all have to give.
since you cannot send it in you should try servicing it yourself. i do not have the link to the service manual on hand but i know there is one out there. download that and get a few torx srewdriver heads(i'm sure there are a few laying around the base) take the phone apart and try it that way. or as i have done in the past firmly press your thumb over a few keys in those rows and run it back and forth a few times, occasionally it can help it the buttons are stuck beneath the casing in some way, or stuck together
if you can connect to a wireless network and get tenetd typed correctly you can get into your phone from the comp using the telnet command on the comp
have you tried the "app for that"?
http://code.google.com/p/androidroot/updates/list
I haven't tried it so I don't know what's involved exactly but it is worth a shot.
simply type out the commands as if your phone were working normally...then use the trackball and backspace key and go back and delete the unnecessary keystrokes
Here's how the keypad works, if you're going to open it up and try to troubleshoot it:
The keys are capacitive, so there's no direct electrical connection when you press one down. There's typically one set of contacts that run in rows, and one set in columns. When you press a key, it activates the sensor in that row and column, whereas the other keys on that row and column only see half the signal. That reduces the number of pins necessary to get inputs from all the keys.
So if you're pressing "e" and getting "e3", the column wire is probably working correctly but you're getting the number row and the top text row.
Try taking it apart and seeing if there's some dust or grit between the keypad and the circuit board. If that's not it, usually there's a ribbon cable that connects the keyboard circuit board with the rest of the phone. Both the socket and the cable itself for this type of connection are notoriously finicky.
Let us know how you make out. Also, why will it be a year until you can get it serviced? Are you in the pokey?
great advice!! and timely too!!!!
Hey guys!,
Thanks for the options, it didn't take long for replies and that shows how wonderful this community really is. I will keep you all informed as to my progress. unfortunately i am going to have to wait until the morning to attempt to find a set of torx head screw drivers. right now its 11:52pm and everything is shut down. No, i am not in the pokey, just unable to get back to the states until then and if you thought the mail service was bad in the states, you should really see this place. i am not going to risk my phone through that service.
ohnoezmahfone, thanks for that information. my gut feeling is it has something to do with that ribbon cable. about 60% of the top two rows of keys are doing the same thing. Now, i have never dropped the phone or jarred it in any way, so i don't know why it just started doing this. but then again, it could be dust too. That one thing this place has plenty of!!! Sand and Dirt!!!. as soon as i get my hands on those torx screwdrivers, i will report back.
Now, if someone has an alternate method that might work before i perform open heart surgery to this android unit, by all means speak up! I can build computers but have never dove into something this small, nor do i have all the tools i am used to having. But i will give it a shot. Whats the worst that can happen? I hose it up and spend 400 on a G2 later this year? . Not a total loss, i guess.
i will follow up soon,
thanks again all!!!

in case you dont have the service manual...

I used it to open one (got wet ) and it made the job very easy! One step at a time, and it really REALLY helps to have a plastic opening tool (or a plastic knife may work in a pinch).

Hopefully I'll never need it, but it's sure nice to have this sitting on my hard drive. Thanks!
gospeed.racer you are a lifesaver!!!! i recommend that .pdf to everyone. It bailed me out of having to enter the "g1, long distance throwing competition". Anyways, i followed the service manual step for step, took the g1 fully apart and when i got to the keypad module i didn't find any dust. kinda feeling like this was all for not, i proceeded to put the phone back together. once complete i powered it on. then i started to type and Holy Crap!!!!! it is fixed. all the keys are the way they should be and soon i will be on my way to rooting my g1!!!!!!
All of you here are outstanding and i am really proud to now be part of this forum. Thank you again, for pointing me in the right direction. I guess it must have been the ribbon cable not being seated correctly, causing my problem. well, not any more!!!!
Red
p.s. BTW i would like to thank all that posted in this thread. i couldn't have done this without you.
awesome that its fixed now. welcome to the world of root
get one of these http://www.androidaccess.com/sdcard/store.html
you wont need the top two rows of your keyboard to use it
it should reset your keyboard once you go back to rc 29 then it will allow you to just enter two commands that will root your phone. you can read about it here:

I bricked my TF300T as hard as possible and I don't want to pay a fortune to asus for fixing my tablet.
So I bought an used mainboard for 75 EUR / 97 US$ and replaced the bricked one.
First, if don't have any experiences in electronic stuff, don't read further.
What ever you do, you do it on your own risc.
Let's start:
Step 1: Case back removed from the tab
Remove the back with your fingernails, popping it open between the black border, and the plastic backing.
Be careful near the buttons and headphone jack.
Step 2: Remove tapes and the heatsink
Take off the heatsink carefully. Some glue fixes it on the cpu.
On the left and on the right site are black or grey tapes. Remove the tapes carefully.
Your tablet looks like this now (see mainboard.jpg)
See mainboard2.jpg for the colored hints.
Step 3: Disconnect the battery (orange loop 1)
Remove the cable with you fingernails. Don't pull the lines!
Pull with you fingernails at both sides of the connector.
Step 4: Disconnect the free cable (orange loop 2,3)
Remove the cable with you fingernails. Don't pull the lines!
Pull with you fingernails at both sides of the connector.
Step 5: Unlock ribbon cable and disconnect (blue loop 4,5,6)
The ribbon cables are locked. To unlock open the locking bar.
Now you can pull off then ribbon cable easily.
Step 7: Remove cameras (red and green loop)
Lift up the parts with the qr-code on.
Step 8: Remove the screws (greens loop)
Step 9: Unfix the ribbon cable from the mainboard (red arrow C)
the buttstraps are sticking on the board. It's easy to tear them off.
Step 10: Remove the board
Caution, don't spoil the ribbon cable (red arrow B). Close to red arrow A is a small black part, made of rubber.
Remember it's position and catch it while you are removing the board.
Done!
Take the new mainboard and install it. Follow the steps in reverse order.
Caution ! . The black pin must fit into the whole of the mainboard! (see pink arrow)
That's all!
Good luck! :good:
Thanks for this. Very appreciated.
I will be ordering a replacement board soon to fix my bricked TF300T. However, I've read that some people found their touch unresponsive after doing this, they were even saying that the touch board and motherboard had to be compatible ?
http://forum.xda-developers.com/showthread.php?t=2091233&
I don't know anything about incompatible motherboards. Probably some ribbon cable were not installed tight enough.
Just ask the mainboard dealer.

Thank you for your detailed instructions and pictures. I was able to successfully remove my main board and replace with a used one from eBay. My bricked Tablet is up and running again for under $70!
Sorry to resurrect an old thread like this, but wanted to say a big thanks for helping me get my bricked tablet back up and running.
I have a question someone might be able to help with - my TF300T is UK and the mobo I replaced was from the US as I couldn't source a 2nd hand UK one.
As far as unlocking, rooting and bootloaders and such do I now treat my whole tablet as a US tablet? Does anyone know? I assume so as it's now listed with build number JOP40D.US_epad-10.6.1.15.3-20130416 but don't want a 2nd brick.
Thanks
Thanks for this tuto, it's help me a lot to change my motherboard
BTW, there is a little switch on the motherboard, that you should turn OFF before plugging or unplugging wires :
So, the right way to change motherboard is :
- set switch to OFF on the old and new MB
- remove wires
- remove MB
- put the new MB
- plug wires
- check all and then set switch to ON

I did replace my logic board also with a spare part from USA, but didn't care and flashed WW SKU - and it worked. But don't sue me if it doesn't work for you.As far as I understand the whole architecture, bootloader is the same on all SKU versions; that counts, because you will change the other partitions anyway by flashing custom ROM. But: don't sue me!
That's cool man, in the end I flashed WW too and the were no problems and I've been running it for months now without issue, so a sample size of 2 says that was the right choice
Picked up a motherboard from US on ebay, got it shipped to UK. Just used this guide and chucked it in my expensive paperweight - MY TABLET LIVES. Thank you Huebinger!
I'm hoping someone can help. I've replaced the motherboard with one I purchased off of ebay (actually a busted screen) for pretty cheap. The issue I'm having, is I do get life, but it's the red led next to the power button blinks twice when I try to power it on. Did I miss something in the repair?
Battery not plugged in securely or needs to charge? That is usually what the red LED is for
Figured out my isse.

Well, I unplugged the battery, and left it on the charger, and it worked fine. so it was my battery that was broken. so technically I replaced the Motherboard for no reason. Oh well,
Thanks for the tutorial. A good suggestion to help understand how and where things flip up, is to watch a video on how to replace the battery, technically most of the cables used in changing out the battery are done for the motherboard too. Good luck all.
So we're currently in a bit of a heat wave here in Brisbane, Australia, and I think the heat has affected the glue on the tape around the power switch ribbon (the unit continually reboots after displaying the Asus logo - doesn't get to the ROM splash screen at all!). Does anyone know how I could look up a part number for it?
I was thinking about doing this, but at this point you are better off buying one of the tablets with Remix OS instead as the TF300T is no youngster anymore.
But the KatKiss Rom makes it a youngster again. Thanks to Timduru!

I guess that's relative, but for productivity purposes, until someone ports Remix OS to this tablet (if they ever do), it is not that great, as the keyboard and trackpad would be great for a multi window ROM such as Remix OS.
Replaced a motherboard on tf300t that Asus quoted me $224 to do, out of warranty ...... Cost $30 to buy motherboard on Ebay. Followed description on the first post and have revived a dead tablet. Thank you, huebinger for your big time help!

Can you provide a link from where you bought it? I'm planning to buy one but don't want to take a risk of getting a bad one.
Struggling with copy and paste but I just went into Ebay.com and searched for motherboards for tf300t. There's a variety of pricing. I opened my tablet and compared what I saw to what was in a picture and take a chance. Mine worked out very well. better than what I would have paid.......the posting with pictures does a nice job of explaining step by step.
Sent from my TF300T using XDA-Developers mobile app
I decided to learn tablets..so I took on a TF300T repair for a friend to start learning.Looks like this TF300T was the wrong choice.
Background.
TF300T Original digi was shattered and was barley working. possible ghost touches
Andriod 4.2.1
Original Digi 5158N FPC-1 06WW 2010 on the sticker JA-DA5158N-IBB 18140-10120500
I did check a few post before I bought a digitizer saw the issues with mixing different versions. So I went with an ebay digi from china with the 5158 model. I received the new on visual inspection it looks exactly the same. New Digi revived no white label but printed in small black ink on the new digi says 5158 12.28 D4\ 11205019701012D. At the bottom in white ink it says 5158N FPC-1 06WW 1225. seems like a match
I replaced the cracked screen went pretty smoothly. I put double sided tape on the digitizer plastic frame after cleaning the old junk off. I did not remove the top cover from the new tape,I just put the unit back together without screw so I could make sure it worked the plan was to test, re tear down then glue/tape the new digitizer down after I tested. Well I get no touch after the 5158N to 5158N swap.
unit loaded the first time and updated the camera firmware but not the touch
I did check the fuse on the main PCB around the LCD/touch connectors and found no burning.
the first time I powered the unit up with the new digi the screen jitterd a bit but no touch. after resetting the cables still no touch. the jitters stopped.. So at this point I ordered a USB adapter to connect a mouse.
This morning I received the mouse connector. went into settings it said. Touchpanel version ELAN-3011-4822 Kernal version 3.1.10-g215ac8bf
Also had a message about DMClient has stopped on first boot. went away after a few reboots.
Today I tried a cold boot after reading some post. It booted up showing the three icons RK/ANDRIOD/WIPE.. up at the top I got the following line:
andriod cardhu-user bootloader <1.00 e> released by "U5_epad-10.6.1.27.5-20130902" A03
key driver not found...booting 05
starting Fastboot USB download protocol
at this point in the cold boot booting the mouse and keyboard seem to be unresponsive. If I hit vol up I get booting kernal recovery image then i get an android logo and big error message sits there and then boots up normal.Still no touch.
After 1st cold boot I went back to check the touchpanel version and now it says ELAN-0000-0000 the Kernal version is a tad different now its 3.1.100-G215ae8bf
Is this normal and Ive missed something? Could it not be working because I ave not glued the new 5158 to the plastic frame?
Do i need to root the device then flash the touch firmware? Seems to me that it should have just accepted the new 5158 and worked that's why i spent the extra cash to avoid this kind of issue.
Any words of wisdom from some TF300T gurus would be a big help!
Forgot to mention at the time i replaced the touch digitizer I did not know to turn the service switch off. the battery was drained as it had ran down to nothing because I could not touch the power off. hopefully this didn't screw me?

Barring any hardware malfunction, the only way to find out is to root the thing and flash the firmware anew through ADB. This issue has been discussed so many times, it hardly warrants a new thread.

Thanks for the response. I apologize for the new thread, most of the other threads seem to deal with swapping mis matched digitizers and then flashing the rom. I thought because mine was an exact digitizer match it may be a different situation. i was just hoping that my experience had rung a bell and someone may point out my error.
At this point I'm pretty sure its not hardware the microsd card reader that shares the touch digitizer board works. and the touch ELAN chanaged to 0000-0000 only after I did a cold boot.

Hi, i have the exact same issue. Also the system/etc/firmware/touch folder does not exist. I made it and put inside fw. The device whenever reboots it doesnt automatically update fw from the touch folder as it should. Through adb shell i always get error. Seems like the mobo not recognising digitizer. I also put the old broken one and still the same ELAN-0000-0000 i also forgot the off switch but i cant find any "weird" coil. Any help would be appreciated. I have read the other thread and learned a lot but nothing specific to this problem. Also my micro sd port was not working and i really thought was the pcb, but then i manually updated to the latest asus fw (from 4.1.1 to 4.2.1) and instantly micro sd works. When it wan on 4.1.1 i could find the touch folder and 04-3021-7038.ekt was inside (no label digitizer was the broken one and the new i bought as well). After the 4.2.1 update the touch folder disappeared and had to remake it. Tried with 04-3021-7038 and 02-3011-4820
(sorry, just saw that there's a help forum - but I don't know to move my post, or if I can.)
I had ordered a screen / middle frame assembly and replaced everything, based on a couple youtube videos (I hadn't run across the replacement thread here at the time). It went pretty smoothly, except for the logic board screw, which I had a difficult time getting out, and more difficult getting back in. All because I was impatient - I was visiting family and away from all my tools. So I ended up using needle nose pliers to get the logic board screw back in, but after I finished, the OPO wouldn't turn on. The screen does display the initial charging animation when plugged in though, so I think it's just not getting the power button click. After opening it back up, it looks like I damaged the ribbon to the power button. - I have attached the best picture I could get.
Any ideas on what my next step should be? It's hard to tell where the apparently exposed wire is run - to the other contact? It's hard to tell if it's shorting, or what.
I would appreciate any ideas or help!
Thanks
