Hey guys, Im trying to fix this mt4g for a friend.. It wont boot, I cant get into hboot or recovery, all it does is flash the LED. I have read post saying its because I was unsuccessful at loading bootloader, however it doesn't vibrate like the others are saying. I left the battery out for a couple hours along with sd and sim, also tried charging through the night... I cannot figure this one out, also, the computer will not recognize any new hardware or drivers. Is this phone bricked beyond repair?

I put the battery on my battery charger and let the battery charge outside of the phone now when I put the battery in the phone and plug it in to the computer, the red LED comes on and stays on, along with a red glow on the trackpad... Anyone know what to do?

Blinking LED is either the battery is charging to at least one percent, or you didn't press the right button combo to boot into bootloader. Power + Volume Down is bootloader, Volume up will give you three vibrates and a flashing LED, where you will have to pull your battery.

Thanks, I cant get the phone to do anything... I plug it in with the battery in, without pushing any buttons and the LED comes on and the IR trackpad light comes on... It wont respond to anything, no drivers popup.. Is there anyway to recover a bricked mt4g? Im new to it, as I have an Evo and have never had anything like this occur with all the evos i've flashed and rooted... If someone knows anyway to fix this feel free to give input..

Thanks everyone!

ya .. mine is doing the samething.

I just try to turn it on and I get one vibrate ... nothing else

I hit down and power and I get one vibrate .. nothing else

I hit up and power I get 3 fast vibrates and a flashing orange led ... I try to plug the USB here and I get 3 fast beeps on the comp

I hit up and down vol and power I get 5 fast vibrates with a solid green led and noting else... usb again beeps 3 times on the comp

neither will recognize the usb and I have reinstalled the drivers .. and of course none will work with adb either.

I think we are screwed really ... but maybe someone knows something i dont on this here. Thanks for any help.

if you fix your phone. let me know

ya .. no luck so far ..I have tried a lot .. different drivers .. HTC sync .. etc.

I have tried different button pushes .. usb ports .. wont work in adb .. nothing is doing anything.

all I hear thru my speakers when I plug it in is that damn the fast 3 beeps .. ike a "hell no go F yourself you arent connecting it"

and there isnt a lot of info online bout this .. other than some others have the same LED blinking and stuff .. I still dont know what the different LED modes mean.

so IM screwed .. BUT I am getting an LG G2X as an alternate exchange thru T-Mobile warranty though. goodbye mytouch 4G :( Hello to G2X AND Galaxy S II(bought) .. fun times!

Its not bricked. Somethign is wacky with the phone, mine has done it and thats why im trying to find out what the hell is going on. My phone acts like its completely dead. This post migt end up being really long.




Ok, i notices this, i used my phone as a wifi hot spot. Turned it off. Left my phone alone, i then put it on charge and went to sleep. Woke up looked at the battery, no color other than the lighting bolt. Unplugged it then went off. Pluged charger back in and orange led flashes. Tried to get into recovery nothing. Tried to power it on, nothing, tried the volume down and power, three vibrations. Ok then i decided to take out the battery in and out, didnt work, tried leaving the battery out for a few minutes, then put it back in, same. Took out memory card, sim card. Then plugged in the charger. Let it sit for awhile then it works. I notice if you dont use the orginal charger that may also be the problem. I dont have my orginal but i used a walmart charger and seems like a super charger and some how charged my battery enough to be booted up, i daily use a charger that i found with the same connection x-( , that could be the problem. I dunno what makes this happen but it happened to me at least three times. I kinda figure the battery or the emmc chip is involved, could be the hotspot, could be anything, but we dont have enough evidence to figure it out, ill try to post what my battery usage on here. I use cm7 and it only happens when i use it. I tried all other roms but no repeats. That was my story.

I have done all these as well, and still unable to get past the black screen, or acheive bootloader as well. I have even left the battery out for a couple of hours, and still no different. Going to try recharging the battery once more, and some other things.

As for adb it is of no help as of now. I keep getting an error saying no device found. Has anyone found a way past this yet, to try rebooting through adb?

*Edit*
After trying to replace files on the sdcard I was not able to get past this issue. Also spoke with tech support, and was not able to get anywhere with their help. After speaking with them, I have come to conclusion the is bricked. I still cannot figure out what caused the phone to do this I broke down and sending it out to be replaced. Thankfully I have the insurance so I don't have to pay anything for the replacement.

Apparently its not bricked cause I'm still using mine. Try a different charger probly a stronger one like walmarts. I think the battery has a fart and is messed up for a little when it doesn't have a good charge

Its not bricked.
Download the stock rom, and put that .zip in the root of your SD card. Put it in, press Power + Volume DOWN and wait for the bootloader. Once it boots, it should recognize the .zip and ask if you want to update it, run the update and your phone will be at stock again. Then root again, install Clockwork, and hopefully you backed up your ROM. This won't effect S-OFF, but you will have to run VisionARY again to get root permissions to run clockwork.

Hope this Helps.

I too had this problem not too long ago. My power button wouldn't work though... I just connected via USB to my computer with the battery out, put it back in while connected and it turned on. Maybe I'm just lucky but give it a try
