Problems with MT4G after digitizer replacement - myTouch 4G Q&A, Help & Troubleshooting

I picked up a MT4G for cheap with a badly cracked digitizer and decided to replace it. I'm not new to taking apart and fixing small electronics so I didn't feel like there should be any problem. I looked over the videos and info about taking apart this phone, and replaced the digitizer with no problem. The problem came when I booted the phone up. it boots into fastboot but when on none of the hard wear buttons work. I can also boot into Hboot by holding up and down while powering on the phone, but after the phone is turned on again none of the hare wear buttons work. Anyone have any suggestions???

either you broke your ribbon or your ribbon is not fully connected in check agian and try

Well it doesn't sound like you broke anything internally because you can boot into fast boot, you probably wiped the phone of software somehow tho, can you choose selections in fastboot menu by pressing the volume and power keys?

No. non of the buttons respond when the phone is on. The funny thing is the buttons respond during power up because I cab boot into Hboot. I'm going to take it apart again and have a good look to see if anything came loose.

Sounds like a strictly software issue, I'm pretty confident that if you can get adb access you can flash a rom through there. Can you mount the phone to your computer?
In the development section there's a guide for getting adb access, if you absolutely can't get the phone to respond than adb is your best bet.

Installed ADB onto my laptop and got it to see the mytouch 4g plugged in by showing the serial number. When I enter commands I get errors, I think the phone may be toast.

No way dude if it's recognizing it you're in the clear, if it gives you errors try to remount, you might want to get one of the developers on this since I'm not so technically proficient.but I do know that it's completely recoverable as of this point

Do you have any suggestions on who to contact?

Have you tried re-formating the phone?

Hey sort for such a late reply, hope you got it working, try contacting option 94 or any one from team royal.

Dead wildfire

Hey guys
I am really sad because my wildfire became handicapped today...
I was playing around with it surfing and playing games
Then I put it on the table played abit on the pc but when I picked it up again the screen didn't turn on when I press unlock I felt feedback so it means the phone works the screen isn't tried restart it vibrates but doesn't turn on screen...
What can be the cause?
Is it because I updated nightlys every two or so days?
Thanks
Plug battery out. And plug it. It happen for me a few times in nightly
Sent from my HTC Wildfire using XDA Premium App
tried everything...
battery pull out, charge it, remove sim\sd... anything...
----
oh and forgot to mention
right before the screen died it went white then it never turned on again
is there a way to flash an rom to the wildfire without touching the device? i.e cable?
i currently have no screen but the device is alive...
Is your screen completely dead? Or only after booting? I.e can you see the bootamimation? Try booting into bootloader mode (volume down + power)
If your screen is completely dead it might be a hardware issue.

Why is this in the Dev Forum? Please move!
Yes perhaps it is in the wrong section but by posting that your basically spamming up the forum.
Anyway on topic i agree find out if it really is your screen or just a dodgy flash of a rom

sorry didnt know where to post,
and no i dont even see the animation... as i turn it on i only feel vibration for a sec then i can hear it boot.. but still no screen..
oddly it was after flashing a nightly..
and as i asked:
can anyone tell me if theres a way to flash RUU without screen ? i suspect it might be a problem with software..
Hmmmm you could get sdk and get mobile on pc screen.
not too sure but exhaust all avenues. Have you tried soft reset?
Vol down + power + trackball

hi,
Download the original RUU from Shipped Rom, it happen to me,,and connect ur Buzz (at least it should be turn on, just white scree thats ok) ,,,and just wait, it will return it to the original 2.1 Eclair,,so u can do unrevoked to root ,,CM7 is not stable, i choose wildpuzzle more fasst and stable.
MC
In my experience with ipods, a white screen is usually a hardware issue (ie it needs changing), which seems to be consistent with what you experience (no startup logo).
I hope it is not the case for you, and that your problem will be solved by flashing a different rom.

HD2 charges but won't turn on

Hi guys. Friend of mine asked me to have a look at her HD2. Problem as stated in thread name. I haven't got the phone yet, but would like to see if anyone has any suggestions. It's standard HTC without any mods at all.
Thanks
Sent from my HTC Desire using XDA App
Do you not get the standard short vibration or any response when trying to turn on? What happens when you connect to a PC? Do you get the Qualcomm in device manager?
Lastly, you are positive she didn't flash anything?
Will report on your questions as soon as I get the phone. Quite positive that she didn't flash anything. Thanks for the reply,at least I have a starting point when I get the device.

Also check the battery pins too. One of the two positive pins or the middle pin may be bent. The middle pin has to be making proper contact with the battery as well as the positive pins. But if the middle pin is not making contact the HD2 will not turn on. Check to see if it will turn on while it is plugged into the charger too.
Right, just spoke to the girl, she said that it does turn on, vibrates, shows pink (i guess red) circle and some small writing and then shuts down. Does it give you any clues? Will get hold of a phone tomorrow. Is there a RUU I could run first of all?

Well if you can not get the HD2 to stay on I would not try flashing any ROM to it. one because that has got to be a hardware problem, two if it shots off in the middle of being flashed it can brick the HD2 then it will have to be JTAGed. If you can get the HD2 to bpot into bootloader and stay on then you can try to reflash the original stock ROM. But I would just try a hard reset first as that will give you the same effect as flashing the stock ROM again, aand get rid of any posinle mobile virus it might have. And before anybody says anything yes there is mobile viruses they are just not that common yet.
To do the reset hold both volume up and down buttons down and power the HD2 on then follow the on screen instructions. Be warned though this will erase all data on the device.
Cool, thanks a lot for your help. I'm pretty sure its software problem, or a virus as she did install something before phone went mad and finally refused to turn on.

[Q] [HELP] Cannot enter bootloader, can still boot android

So, I cannot seem to get into bootloader on an HD2. This isn't my phone and I did not perform the original flash, so I'm not quite as familiar with the HD2 toolchain.
The problem is simple, I cannot load into the tri color bootloader. I haven't ever been able to, so I don't have anything to trace to what apparently removed it.
I still can however use MAGLDR to boot android from NAND and flash android roms etc.
The trouble is this phone needs to be shipped to HTC for repair and I need to restore to stock, but I cannot reach boot loader to use any tools or flash any stock roms etc. I saw something on the JTAG restore product but I thought wasn't ideal if still under warranty.
Pretty desperate here since the warranty period ends real soon. thanks for any help!
Just to make sure....In order to reach the boot loader screen, you need to turn off the phone and then hold the volume down button and power button until the boot loader screen pops up. Just making sure you did this!
yeah, been trying that to no avail
Can still get to MAGDLR real easy though.
thanks

Out of curiosity, are any of your buttons not working?
most are working just fine. Only weird this is the red hang up\power button brings up the shut down menu on a single press from time to time once inside android. I believe it to be caused the original issue (random boot lock ups that take anywhere from 2 min to boot android or 25 min, or doesn't at all before battery dies) but this phone has been so flaky its been impossible at times to reproduce results.

HI,
My reply was not relevant.
Sorry I could not help.
If I am reading right this sounds like a similar issue which I had. I went from my car which had really cold A/C and then went to my room which was really hot. There was condensation on the phone and did not think much of it. My buttons started either acting strange or not working. First I tried putting the phone in some rice as rice tends to attract water molecules. This did not work. I then sprayed windex with the phone off and batter, sdcard, simcard out and then wiped down the phone put it in the rice for about an hour or 2. After I did this a few times my buttons started working normal again. No more safe mode and all my buttons work.
Either that or your volume down button is just not working. In which case I don't believe there is any other way to enter the bootloader. If you can connect through microsoft activesync you may be able to restore the original windows 6.5 that way.
Only thing is the vol down button works fine once boot in android. Power button is only weird one and its only acting up depending on the moon phase apparently.

Ok so I was searching for some links on using active sync to flash but any guide I find also is using HSPL to do the flash which is not apparently present on the device. Would you happen to have any links on performing a flash via active sync that doesn't involve any sort of SPL?
Thanks a bunch
Sent from my HTC Vision using XDA App
HSPL is what is used to flash any rom that is not an original from tmobile. SPL is the original that would have come onto the phone and locks the phone from installing any roms except tmobile. With the hspl program you need to be able to boot into boot loader. I have tried windows mobile device center which is what is used in windows 7 instead of active sync but it does not connect. I am afraid that you are stuck unless you can get into boot loader somehow. The only way I know is to hold the volume down button as soon as you power the phone on.

I'm sending mine back to HTC
FINALLY!
All I did was...wait. I took the battery out for a couple hours, and tried again and bam it came up! I tried for like two days before this. I then followed the standard LEOIMG.nbh to the sd card and it restored win mobile and SPL just fine.
I guess it sounds crazy but just take the battery out for a while or overnight perhaps. I really didn't do anything so that's all I have to offer.
I think this HD2 has an overheating issue or something because it starts to act up once on after a while (power button...boot problems as described above).

Check SPL problems

Awesome guides! No doubt about that. I'm not a complete noob but I am new to the HD2 and I feel stupid bc I can't get past the first step I am frustrated cuz I have been looking all over for ways to check SPL my trio screen that everyone talks about is not coming up. Idk what to do. I've done the volume down with power button and also tried pressing the reset button in the back just to see if it works. I boot into Windows to make sure the volume down works and it does.
I have the tmobile version Leo 1024. Any suggestions.

Pull battery, press volume down and hold, push power and hold both. Tri color screen should be there.
Sent from my HD2 using xda premium
Like everyone says. Volume down + end key.
Hold the volume down until the tri-color screen shows up.
I know you've said that.. just make sure you continue to hold volume down
Maybe that will help.
thank you guys but idk why it is not working but i finally managed to get it to bootloader by trying to install hspl3 it automatically sent me to the bootloader screen. After it said "we hacked it" i rebooted and tried to see if it would work with the typical hardware button
voldwn + power button and then let go and it still does not work.? :/
ps . i let go of power button but kept holding the voldwn and still did not work.

You are completely turning off your phone and then doing this to power it up right?
Sent from my HD2 using xda premium
Yes and so I started following your guide to install clk since I know that I at least now have hspl3 installed and in the part where you task29 I followed instructions successfully flashed. Everything is going well until you say to reboot into boot loader mode by removing battery and voldwn + power. I try it hoping it would finally work and it doesn't.
Make story short my phone is stuck at the "stick together" screen. I tried getting into boot loader mode by running the hspl install program but bc is stuck on the screen comp is not able to recognize phone. Am I bricked?
Btw I pm you Kylew

Nice, real slick move,, you can't get into bootloader, yet you still decide to go ahead and wipe the OS, so now you have a non booting phone and no access to bootloader.
That's a handsome if totally useless lump of glass and plastic you have there!
JTAG, or sell for spares. (Well, after trying everything you can think of, but all I can think of is freezer trick, but its a loooooong shot. )

what is jtag and whats the freezer trick? is there any other way to get into bootloader mode maybe with sd?
Im willing to open the phone and remove or unplug a strip to completely erase any stored data and hope that it boots into bootloader?
SOLVED!! hope this helps someone else
i got it to work. My god there are soo many ppl with this phone soo many threads and post not sure if thats a good or bad thing lol anyways out of all the searching I found this guy to have had the same as me and he solved it. It was impossible for me to ever i mean EVER boot in to the trio color screen or bootloader what ever its called using the hardware buttons even tho the hardware buttons do work. I was able to get into bootloader when comp and phone sync and I used the hspl3 program to boot the phone when it was fully on the win mo stock.
Anyways I just followed this :
http://forum.xda-developers.com/showpost.php?p=10644926&postcount=4
I opened up my hd2 (unscrew and removed the back panel) and disconnected the connector flex rigid board (A board) of the hardware keypad from the mainboard….and pushed the battery in and pressed reset (sometime u need to plugin the usb cable to wall charged/pc to wake up the phone) and held volume down key and hopped for some miracle.
Viola saw the tricolor screen after eternity – since the back panel (not backcover) was open I help the battery to the pins and didn’t even move my fingers …run the stock rom installation and held the battery tight in place and waited to get the rom completed…the moment its 100% relaxed my fingers and reconnected the flexboard connector, re-assembled my phone and everything was back to normal.
I also used these pages for reference on parts:
http://www.ifixit.com/pdf/ifixit/guide_5919_en.pdf
http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
ps. no need to take the whole phone apart. I believe you are disconecting the AP FPC from main board which is connected to your hardware buttons if I am correct.
Edit: I want to give credit to kylew1212 for walking me through the rest of the installation of my android.
Interesting, good job.
i have a lot of sympathy for his viewson peace

MyTouch Q bricked

First of all I'm sorry if this is in the wrong section. I can't for the life of me find a section specifically for the myTouch Q so i usually just go ahead to the glacier thread.
But My phone is bricked. It loads the LG and myTouch Screen, then goes to the lock screen (draw pattern) But i cant touch the screen at all. The background is black, and its a matter of minutes before shutting off again and repeating the cycle.
I know that going into bootloader will solve my problem but the phone has no physical buttons. So I cant hit any buttons for a factory reset. I checked all over the internet but cant find any good info on the Q and its touch bottons.
Sorry buddy, but your right , this is the wrong forum. Are you sure there is no hard way to get into the bootloader ?
Sent from my HTC Glacier using XDA
I have no idea. I can't use the phone at all since I cant do anything at lock screen. I was thinking that there would be another way for bootloader maybe by usb or a software but nothing.

What do you mean? does the Q not ship with physical buttons? I doubt that, but I havnt looked at the phone much. Or do you mean ur physical buttons are broken?
IF they are broken u are most likely out of luck, unless u can hold down the power button for that menu to pop up. then u can press reboot and press bootloader or recovery. That is, IF the rom supports it.
also u never stated if the phone was rooted and had a custom rom. that would make a huge help
The phone has pressure sensitive buttons unlike the MY4G. So the Menu, Power, Volume factory reset is i think not usable
It's rooted but doesnt have a custom rom. I am using another launcher though if that helps
never mind I found out. It's a little different for this phone
cant provide url to page but thanks
Just when I got interested, he bailed! The suspense is gonna make me Google it myself!
