My Universal Dead . Please help...

Hi,
My Universal fail to power on.
It do not enter boot loader with light + power + reset and show no signs of life. Batteries are both new and tested in other working units.
When connected to USB, PC reports "USB device not recognised"
I had ROMS flashed but failed at 99%. When reset the units did not power on or showed any signs of life.
It had been working fine up until the unsucssesful flash update.
I would like to be able to use it for work .
Please either post replies here or email me [email protected]
Your time and efforts will be greatly appreciated.

Please try to enter the bootloader mode in a bright room as it is very difficult to see in poorly lit environment. Till you enter the bootloader mode your device will not be recognised. Perhaps one of the three keys is getting released..the light button is the usual culprit. Once you are in the bootloader you can reflash.

Thank d_ranade for your answer.
I am sure the screen is 'all black' and I've tried to press the buttons several times.
I think the main problem now is how to enter the Bootloader.

I sometimes find it takes several goes to get into Bootloader mode. If not, have you tried a hard reset?

I've tried whatever i can do. Hard reset is useless too.

Unable to start/see bootloader
I seem to have the same problem with my upgraded universal which was working fine for about ten days. Then I installed TomTom on it and again it was all working that evening.
Then, when I turned it on the screen went blank (white), so I re-flashed it, but, part way through the screen went black, so I left it connected for further hour and nothing. I have since been unable to get it to do anything, it is not recognised by activesynch, it will not charge (either from the mains or the USB on either of the batteries) nor will it turn on or respond in any way.
I have unset ‘allow usb connections’. I have tried solidly for +/-10 minutes doing the backlight + on/off button and reset bit - repeatedly, with my wife helping to ensure all buttons were being pressed. All I got was a message from MicroSoft telling me that ‘One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it’. The only positive thing is that every time I do it and depress the reset, the red LED flashes (provided I leave the USB cable in) but at no point have either of us been able to see any writing on the screen.
Any guidance (apart from where to take it for recycling) would be welcome…

It happened to me several times too. Even in the old ROMS. But had learned many things out of it. I removed the battery. Wait for several seconds or maybe minute before placing it back. And after placing it back wait again for some time before doing the "power + light + reset" (bootloader). At some point when I am in the bootloader mode already and reflashing, connected to the PC already, the screen went blank again. So I'm sure that something went wrong again. I repeated the procedure again (removing battery, placing it back etc...) and the reflashing continued. It takes patience (maybe).
After having experienced this so many times, I'm beginning to assume that it is not because the battery is "bad" or there is a problem on the ROM being reflashed. It is on how it (the battery) is connected to the unit. The reason why it does not turn on, charge even if connected to the charger, does not hard reset, does not react to anything... I just don't know.
One thing more, the procedure I said above sometimes does not work at once. But at least I managed to "resurrect" my device several times.
This I am sure, it is not in the ROM that is being flashed or the update...
Hope this helps,
Lelen

lelen, Thanks for your assistance. I tried last night, but it still could not enter the bootloader mode...

I have the same problem =( and i don't know what to do, someone told me that i have to change motherbord to resolve this problem, i hope there are some other solutions.

Dead Uni
I too had this problem. With the device not responding at all and not able to enter bootloader stops mtty from working.
Only way i could get it to work was to take it to an O2 shop to send it away for repair (luckily the O2 XDA range has a 2 year warranty and because its completely dead they cant tell the OS has been modified).
Unfortunatly like the previous post i think it can only be fixed by replacing the mainboard.

Hi all, i found this thread http://forum.xda-developers.com/showthread.php?t=291097&page=6
so many people have the same problem , and nobody found a solution? i can't believe that on all this universals died motherboard, and there is no way to fix it with some special cable or some programm.

yes,i post the last reply of the thread you mentioned above, but nobody can resolve it.

I recommend you remove the battery and leave it over night. Put the battery back on, ensure it is properly mouted and try booting it.
It worked for some, no idea why though. I'm actually suspecting a bad battery mounting, which results in the motherboard unable to detect a battery is iserted, thus refusing to boot.

finally managed to get mine fixed, mine was out of warranty too and sent it off to carphone warehouse express service, took 3 weeks but was fixed with a standard chargeable repair charge of £40

I have a somewhat similar problem but not from upgrading. I accidentally dropped the device after a successful upgrade and the screen got damaged. Someone picked it up, opened it and noticed it was on even though the screen was damaged, and then closed it back. By the time I got it back it was dead and could not come on again. I have since replaced the damaged screen, but the device will not come on and cannot enter bootloader either. The device get warm if the battery is left on.

Black Screen of Muerto!

during a rom upgrade some time back, my screen started to fade, at first very very dark etc, the just black.
I could not connect diamond to pc (never even came up as a usb device) it was dead!!
The phone was hard spl'd and had been through 20 or so roms without issues...
I have managed to re hard spl it,, put radio back to 25, and put an old simple duty rom...
it now active syncs, receives calls, etc
but screen is black????
any clues besides ebay??

Does the screen turn on at all when you Hard SLPed it?

NO, no lights on Unit anywhere
Not even below on the Phone or Home buttons etc, the unit has 0 lighting power at all times (after hard reset, after hard spl etc) , but it active syncs etc. and makes sounds??
Is it software or hardware? Strange thing is this happened after a rome upgrade, which makes me think software, but I have upgraded, re hard spl-d numerous times to know affect.
So if hardware, I can see new sreens on ebay for 20GBP delivered, and I was thinking of ordering them if they are not too hard to install?
Any input appreciated
it appears after a rom flash, now the screen seems to be actually light in black for awhile, so slowly patient is being revived but I still do not know how to get it back...
UPDATE: Screen came back but on low power (ie no backlight) and it is now stuck installing opera??: bug Microp Mismatch during installation. We are slowly getting there

ok - if it's software, the best way is mtty - as far as i can tell, it'll make sure everything is wiped out...
but from the sound of it... u said it went down while upgrading - so i might not be the software, coz while upgrading (%ages shown) software is being "written" - but it's not really "active"...
but worth a try:

good luck

Updates: Lights on Bottom coming on
I am having a difficult time getting MTTY to work, but the device white lights on the lower end of the screen turn on now. (when I seem to reset the device etc)
I can update the rom to other roms without problems, is there a reason to use mtty to update or should I just order a new screen?
UPDATE: Energy Rom works! but screen is very dim, no brightness, and I get this infamous Microp error???
looks i'm still screwed this is a hardware error...screen went black again...

Phone always has a white screen, but seems to work

Hi Forum,
I got a dash with the WM 6.1 from this great forum.
Somehow since yesterday the screen turned completely white
There was no physical impact on the phone what so ever...
When I turn the phone on, the screen is all the time white... but the phone is still working since the alarm is still ringing....
I've tried already the following:
- took the battery out for over 6 hours and tried again
- with and without sim/sd card
- to reset the phone but with no success since I cant see anything (2 softbuttons, powerbutton etc.)
- putting WM 6.5 with no success with the Error 270
- pressing and holding any button
- tipping the jagger for 3 times
- and finally hitting the phone
All these steps didnt use me anything...
I'd be gratefull for any sudgestions
Maybe the screen is just damaged and its not because of the software...
thanks a lot,
RedDot69

Hard-reset will be best option and can be done blind since it's button sequence as known then green key, i knopw that peeps have done it blind and with you spending enough time it will be sorted... The other option is bootloader and flash your stock ROM as won't get an error 270

thanks for the fast reply.
ok about the hard reset.
I hold both buttons beside green and red button then while holding i turn on the phone (power button more then 3 sec.) after it turned on i let go of the buttons and press the green button (I pressed it a several times). What after that?? will everything happen automatically??
if yes then the hard reset wont help since its still white...
unfortunately I dont have the original ROM anymore (WM5).
Do you know where I can get it??

Ok I guess I managed to hard reset this thing.
Unfortunately with no success
can anyone help?
will the problem be gone if I change the display?

Can you sync with your PC? That's something that you haven't state in your original post.

From what you have posted in the first post, looks to me like your phone has suffered water/moisture damage. Classic white screen, nothing shows, display turns off after default timeout seconds, phone functions smoothly. For this to occur, you dont have to dunk the phone in water, phone in pocket when exposed to light rain, snow will do it.
If this is the case, the first thing you can do to salvage the phone is to remove the battery, otherwise the charge will short circuit more, leading to irreparable damage.
Second thing, try and keep it open for 24 hours or more and try ONCE more, just once, if the moisture has been evaporated. If not, remove battery again.
Next you will need to find a service center where they will dismantle the phone and physically air dry the PCB, and hopefully if it hasnt already shorted, it will come back to life.
The cost for this could vary from minimal to astronomical, depending upon which country you are in.
Do not take my words for granted, do a google for phone water damage, find out if those are your exact symptoms.
All the best.

yes I can. I already saved the contact list The phone is perfectly working beside the white display...
@ ccpraveen
I really dont think thats the case. Since I was sleeping on the couch, the phone's alarm went of like at 11 and it was all ok, then 30 min later the screen was all white
And the night before I left the phone at home...
Bringing the phone to some service center is out of question, since I live in Germany... If possible, I'd have to repair it my self...
By the way the Display time out works too... Somehow I got the feeling that it wouldnt use me anything to change the display

please, can no one help

install this on your computer http://www.mymobiler.com/
it will silently install on your s620 when it syncs with activesync and you will be able to view your screen from your computer monitor
if everything works buy a new lcd from ebay and replace it because its probably broken

--- sorry didnt want to post ---
Please skip this reply and read the next (cant delete this anymore)

My impression is that you have a hardware problem, maybe your screen has something loose. If you state that you will fix it by yourself, you can read the sticky on how to take apart your dash.

There are also power management settings that will turn the display white, however if it is white all the time, then it's probably hardware. Loose connections does sound possible. I'd check that first

You can try the following:
*- COMPLETELY disassemble your phone.
*- Take the PCBs apart on a table or something.
Then... take an hairdryer!!!
You have to dry your PCBs: take a PCB in your hand and do the work.
Be aware of not using TOO HOT air, or you'll melt all.
If it doesn't work, try to dry your LCD.
Doesn't work?
Okay, then the only 2 possible fixes are:
*- Replace the LCD Flex Cable if not integrated in the LCD.
*- Replace the LCD.
Hope that you'll get your phone fixed and running

fault - no display, can only see backlight

ROM: LeeDroid v1.3 i think
Recovery: Clockwork
Over the week I've noticed my screen been playing up abit. The display sometimes went dim (though it was natural due to my auto brightness).
Today, I cannot see my screen at all. Did the obvious troubleshooting steps.
- take out battery, simcard, sdcard,
- insert battery, enter to recovery mode
nothing, I can feel the phone vibrate on bootup, still no display.
Was thinking sending it away for warranty, but the phone has been rooted.
Will this cause any issues?

I suppose it will cause issues. Except if they swap it instantly in service.
The only thing you can do is to run a 1, 32 ruu and than if it does not fix going blindly and try to revert ENG s-off if you had.

I was haa similar issue. The lockscreen would show for like 2 seconds after boot but then the screen would go black and the backlight would still be on It was like my phone had frozen with the screen off. I flashed the rom again but without wiping so i could backup everything then done a full wipe.
Leedroid 1.4.1

To be honest, I was reading the Limited Warranty pamphlet that was in the phone's box last night.
It explicitly states that ONLY hardware components is covered by the limited warranty and specifically excluded software and accessories from the limited warranty. (Sorry, dont have the exact wording now, but it is noted in point 4)
So if there is no warranty on software, how can modifying the software that does not alter the function of the hardware void your warranty?
I am no lawyer, but this sounds pretty straight forward to me.
I highly doubt it will hold up in court, if tested.
If they do contest it. Tell them to put on the default stock ROM and see if the problem still persist.

[Q]Help, Phone does not turn on

My friend is running CM 7 on his Tmobile G2.
He was describing that yesterday was acting weird with market downloads.
Here is what he he emailed me on what happened.
the phone was acting normal throughout my day until the evening towards the night, i noticed it failed to finish downloading the update for google earth along with google maps. the phone was fine, and then i pulled it out of my pocket a few times and saw multiple times that it was randomly turned off. i would turn it back on and it would still give me the same issue. when i got home and plugged it in to charge, it would boot and then get to the main home screen telling me that google maps is downloading to update. however the update would be frozen, and a few seconds later the phone would freeze altogether, forcing me to turn it off by pulling out the battery. this happened about 4 times, and now has reached the point that it has become a brick and refuses to turn on or show the charging light
any suggestions on what might be wrong with the phone? Thanks in advance. Im running Cm7 on my phone and never experienced this issue.

same happend to me 3days ago, phone running then freezed... bootloop after batterypull... recovery worked for 2 times but had problems with flashing new rom/backing up -> errors with cache partition...
after 4hours of letting it stay off -> it wont turn on again und wont charge (no LED)
tried it with another dz battery+charger... no change... i wrote htc and they answered within 1hr that i have to send it in without battery...
i guess its a known problem (or why wouldnt they want to have me sending in charger+battery .. if its a power-on problem..)
there are semibrick threads here and in other forums.. but they all don't suffer from the power on problem... so i guess i did the right thing sending it in
edit: never had heat issues, never had random reboots, no overclock, no indication of an update from any app did any harm to my phone, running cm7 for 3 weeks without any problems, no hboot flash, no radio flash ... nothing that would indicate a risk of brick (according to guides & forum threads)... first htc that ever failed for me ;(

Thanks for the reply. I will forward it to my friend. I think he is going to try to exchange it at the store and if it all fails we are going to try HTC.

have any of you tried to boot into recovery? did you have eng-hboot on your devices? go to #g2root

its complete dead as in dead... no LED light, no turn on, no hboot mode (or what its called when you press vol+power key).... i dont have a g2 but a unbranded european dz.. hboot and radio was never touched by me

Similar thing happened to me. My phone kept frozing on me running cm7..was fine for a week though.
So I booted into recovery..wiped cache,factory reset flashed another rom got bunch of erros recovery thing rebooted stuck i n htc logo for like 20min yanked out battery rebooted and it never rebooted back. No hboot,no nothing.
My light indicator still worked though but no hboot or anything.. got a new one now have to send the old one back to tmobile but I'm scared that they're gonna charge me for removing void stickers.
Even though I checked twice that removing void sticker won't avoid warranty according to tmobile customer chat sevice..
So I'm thinking about swiping out the sticker that contains serial number and such on back of our phone with the old one and tell them the new one came without a void sticker lolol
Sorry I got way off topic rofl..

We went to the store today and exchanged it for another g2. The guy didnt ask any questions and exchanged it happily for a new one.

This very same thing happened to me today. Updated to CM 7.0.3 from 7.0.1 and the phone was freezing when installing items from the market. Pulled the battery and the phone was stuck on the boot animation. Pulled the battery again, and now it will not start at all. No charging light, no nothing. Had more than 50% charge, and now it seems entirely unresponsive. I can't use the power w/ volume button technique either, because the phone does not respond.
Seems like somehow I have bricked the phone, or the phone just coincidentally died just after updating to CM 7.0.3? (seems unlikely)

just a short update on my case:
i got the mobile back from HTC repairs.
they exchanged my "mainboard" (changed IMEI) under warranty.
i don't know what emmc chip i had before cause it died so fast, but my usb deviceIDs changed completely and are now simmilar to the ones in the cm wiki.
my current emmc is now:
$ cat /sys/devices/platform/msm_sdcc.2/mmc_host/mmc0/mmc0:0001/name
