[Q] Potential brick? Device not powering on

Hi all, i have a ZTE blade which i have rooted and flashed CM 7.0 successfully without upgrading the radio to GEN2. I've done this and much more without problems, however today for some reason the phone isnt even powering on. The only thing i did before was installing theft aware 2.0. Note that i dont have a SIM card inserted so it's unlikely that someone have sent a command that turned the phone into a... vegetable.
I tried removing the battery and trying to turn it on, nothing. I tried connecting it to the USB power charger without a battery, still nothing. This phone is supposed to be a birthday gift for my friends 30th birthday, so i'd really appriciate help getting it back to life.
Thanks in advance
EDIT: I've tried the following: with ADB devices the phone dosen't show up.
Trying entering field test mode with VOLUME DOWN + POWER key does not do anything. same result with VOLUME UP + POWER.
Tried different USB cords without success.

Have you tried holding volume up & down together along with the power button. Make sure you have the usb cable connected from the phone to a pc. So long as you have the zte drivers, it should show up in DFU mode in device manager (from what I remember).
I think from there you can flash recovery using fastboot again.

I tried that, nothing happens. Thing is, the phone dosen't give any kind of life signal at all, not even the button backlights turns on during charging. Could it be that it suffers from a hardware defect? Or is there more things i can try?

Yeah sounds like you may have a hardware issue; especially if none of the LEDs flicker on when trying the above.
hmm, ....out of ideas for now fella.

Any news on this?
I am having the exact issue, phone is like a real brick:
- Won't do anything when trying to press power and/or any other buttons one by one or at the same time
- Won't do anything with or without battery
- Won't do anything when pluging it to the USB/Charger, not even a led response
- I've tried with and without sim, with and without sd card, trie everything and still nothing, seems complketely without any kind of life inside. The only thing it does is get heat when you put it to charge with battery
I had it with cyanogen 7, max overclock to 710mhz, min arround 200, and it happened (turned off) 5 minutes after I installed Launcher Pro...
Any ideas?

I actually gave up and sent it in for service which returned me a brand new one. I suspect that ZTE dosen't have much of quality controls since a friend also suffered a case of "true-death" on her unmodified ZTE blade...

Similar issue here. If I press the power button (with or without any combination of other buttons) it just vibrates - no lights, display or sound. Doesn't power on so no fastboot/adb etc. Same behaviour with battery, charger, or both. If I hold the power button the vibration sort of pulses, a vibration every 0.75 seconds or so. I recently opened it up to get dust out from behind the screen, so no warranty :-(
Will ask at the shop what the options are for maybe paying for a repair..

Your issue is different than the one i had, you phone is at least being powered on since its vibrating.
Most likely you broke when you opened it or you simply didn't reassemble it correctly - if i were you i'd do it again and check that all the connectors are connected.
If its a software issue, you can always try TPT - total phone transfer. google it, i read it but didnt try it myself so i cant vouch for how it works.

[Q] HD2 WP7 Mango out of battery keeps rebooting

I don't know if it is the same kind of pb linked to the SD-card, but there is mine:
I have just flashed the Mango with marketplace ROM;worked perfectly! (a bit slow sometime, but nothing really bad). I used it a lot today.
I think I ran out of battery tonight, and now when I plug the phone on power, the phone boots automatically (so stops charging...) and loads to DFT screen few seconds and shuts down (because of the battery?) then charge 1 sec, then turn on, .... etc.
Of course it restarts before the battery charges again after the system loading.
(Question here, does the battery keeps charging when the phone is booting? as the orange charging led is off.)
I might have found a way to stop drain the battery trying to start and stop at the magldr menu... but still don't know if it charges because the led is off.
Any recommendation/advice for me? (To avoid the auto-boot on charging)
(I can't (don't want to) re-flash, because the battery is almost dead!)
Thx
EDIT: I have used the original SD-card of 2GB, I also have a 8GB/Kingston/class4 that I didn't want to format, but if I need I can do it.
It seems that the phone is charging when it is on the magldr menu because the system loading goes much further (but the points animation is very slow when it was very smoothy before, like 1 transition per second)
Still loading after 2min
1. SanDisk 2GB Class2 (Bundled with EU HD2) - could install WP7, card was recognized, after one day of using and installing several apps the system starts to crash, random reboots each 20 minutes or so.
2. Kingston 8GB Class4 (Bought 1 month ago) - WP7 installs but can't get over startup configuration, it stucks, rebootings and Hard Resets won't help (tried a bunch of different ROMs, nothing helps)

seems dead for both cards, but I will try anyway with the second one if I can't boot the system anymore!

After 30 min charging on the magldr menu the phone starts again! Everything seems to be ok, but I am still wondering WHY it is not possible to charge the phone without it to start and try to load windows... Or maybe I missed something...?

I had the exact same problem let phone die... couldnt recharge i just used task29 wiped magldr let phone charge while was off :-\
The reason it wont charge during boot is reason why ur keyboard/mouse dont work and flash on and off during actual booting of windows... dont know what process that is .. but i can only imagine its something from going bios (using those drivers) then going to the operating system (utilizing those drivers) and inbetween doesnt work

I got the same issue. I put it to charge and refrained from entering my pin when it asked to, until the phone got a full charge. Looks all fine now...
Out of topic, may I ask how much storage your phone shows in settings with your Sandisk 2gb card? I also got the same card, and it got only 35 MB total storage and 0MB left. That's right after installation...

Sorry, but I don't know. After booting, it rebooted few times then couldn't find the SD-card anymore, so I formated the SD, took the other and reflash.
Then new one (kingston 8GB class4) is showing 7.22 total / 6.80 available. It has been working great today, and still

The best way to get around this problem if you run your battery dead is:
-Hold both the volume up and down keys while the phone is booting
-It will ask if you want to delete your data, just leave it as is for 10-15 minutes
-Pull the battery and restart your phone
The battery doesn't charge while booting up, so that's why it gets stuck in a boot loop like that.

Hum, just pressing the red button enters the magldr menu, maybe safer than the erase data menu There you can also charge the phone without draining too much.

Yes there is this kind of a problem this is how i solved that!
First of all i rebooted, the device was almost %0 percent of battery.
I just plug it to electricity and close its lcd and wait. I dont know why.. Charging device takes very long time. But it still works. Battery drainage is because of huge LCD, i think the battery drainage caused by the lcd canot be compansated by the charging state, so it keeps rebooting everytime.
When you get you first opportunity, please try turning off the lcd.

unless your charging from a laptop which may only give you 200mA the power from the USB will be more than enough to keep it alive with the screen on. the reason it keeps rebooting is because your sucking the last remaining mA out of the battery, like a sponge, it takes several squeezes to get all the water out, DO NOT keep doing this, or you will need to invest in an external charger or attach some wires directly to the terminals of the battery.....or use a WM HD2!
as others have mentioned, put it in to bootloader(best choice) hold VOL DOWN on restart and theres no chance of deleting data here! or put it in to magldr.
dont leave for any longer than 30min though, get it charging in windows as soon as its got enough to boot, its unclear if the battery full cut off works in the bootloader/magldr

I've been using the Magldr to charge my battery on the occasions when the battery gets too low. Today I managed to wait to long I guess. Even in magldr my phone sits for a minute then reboots itself. I also tried the hard reset screen. I don't have an external charger. Any ideas for me?

I have the same problem when I use my HTC charger. But when I use my Samsung charger (came with my Galaxy Ace) HD2 boots normally. Also I noticed that when I use the phone on HTC charger battery keeps droping. I think it uses more power then the HTC charger charges. With my Samsung charger i dont have this problem.

I tried charging in MAGDLR menu, but that only drained the battery more. (v1.13) I had to buy a universal charger ($4) to get my phone working again.
Any idea why this hasn't been fixed in MAGDLR yet? Or might there be an alternative?
For now, I think I will program Tasker to shutdown the phone at 10% battery...

worked for me! thanks

no boot, no lights, not anything =S

hi, sorry to disturb with an usual question around here, (yep, i used the search function) i got a hd2 about 3 hours ago (TMOUS, T-mobile below the speaker and red and green buttons)
so, i went to support.t-mobile.com/docs/DOC-1173 and download the .exe in step 4, i open it with winrar and try it to make the SD upgrade, format (8 gig sd micro in fat32) and reboot the phone in bootloader mode (vol down and power, and yes, i rename it too)
(NOTE: the page asked for my imei, i entered the one behind the battery and it gave me the download link)
the phone innmediately started upgrading.
it get stuck at 8-10% of the upgrade for about 15 mins... in a stupid moment, i took the battery off and put it again... you know, to try again.
No lights, no vibrate, no screen, nothing, tried the usb battery charger, nothing, tried the wall battery charger, nothing, not a led in the phone, and is still dead, the pins are ok, i checked that about for 30 times, noooooooothing.
the software package name is: T-Mobile_HD2_MR_Software_3.14.531.1. (it´s an .exe)
Any ideas? please? anyone?
other things:
no softreset
no hardreset
doesn´t charge
battery seems fine (it was about 75% when i try the first upgrade)
oh, sidenote: i tried to install the stock ...firmware? because the cell was stuck on "stick togheter" and was trying to unblock it, and the "insert code to unlock" never came up, btw (if this is relevant) i was trying to boot the phone with and without incorrect sim, and got stuck, with and without sd memory, and same, only about three times in around 3 hours, the phone booted normal into windows 6.5 and launch htc sense, that´s why my guess was that the guy that sold me the phone make a mistake upgrading it.
ok... i think that´s it. Sorry for the choppy english, it´s 2.30 in the morning around here =P
Any one got an idea? Thanks in advance!

power down your phone.
pres volume down button. (keep it pressed)
pres power button.
you should be able to see a multicolor background. plug in your cable let it install the needed drivers start your favorite rom + flash tool and ur done

[Q] HTC HD2 won't turn on<don't recognise Charger or USB

Hi,I have a Android gingerbread 2.3,haspl v.3,MAGLDR113,it's second time my htc block and dont want to restart from the buton,i have remove the battery and it dosnt want to turn on ,there is no screen,the battery was charget,but the red light don't light when i plug the cabel,in my PC dont recognise usb,nothing and the phone,i try for 1 day to remove a battery,but no result,1st time when it happens it work,but for a week i can't use it,Sorry For my English,Some ideas what can i do before i took it back in the store

sounds like it could be a simple flat battery. when magldr is installed you cannot charge the phone unless android is running, so when it is off it does not charge.
if you can try another battery, or your battery in a winmo hd2, that will tell you if its teh battery.
If you have a spare usb cable (any type, doesnt have to be a hd2 micro usb cable) cut end off, bare red and black, hold red to + and black to - on teh battery for about a minute, which should give it enough power to charge.
Also check very carefully that you dont have a bent battery pin from all teh battery in/out. they bend easily.

i hava a Bat charger and charge the bat all night,and the morning it show me that bat is charget,put it on the phone,but nothing ... cant turn on

Maybe battery is dead. Do you own a volt meter an can check the voltage provided by the battery? It shoud show up about 4 volt.

i took the bat to my friend with devace to check the battery,and everything is OK,but the phone didn't turn on,Can i reinstal the Android ?and how can i do it

Is there a program that can connect to the phone and erase everything

To wipe the phone install the HD2 toolkit, you can download it here.
It includes every tool needed for maintaining your HD2.
Be sure to install the drivers!
Start the program and press the Task29 button, follow the instructions provided. When it's finished your HD2 will be fully wiped, so you would need to reinstall everything.
Do so by doing a MAGLDR repartition. After that choose MAGLDR update recovery to flash the Clockworkmod recovery.
Then go into the Clockworkmod recovery and flash your rom.
Now your HD2 should be fully wiped
BUT! If your PC doesn't even recognize your HD2, and you can't even get to the bootloader screen by pressing and holding both volume down and the "end call" button. Then it's probably a hardware failure.

Magldr repartition flashes cwm so no need for the update recovery step. That's for, well the clue is in the name,,, updating the cwm version on an already partitioned instal.

Okay, thanks for clarifying that!
Didn't know it worked like that, I only use CLK.

Electrical surge, perhaps? Overheated circuits? Who knows.

Somehow the phone start,I have put on my router,and plug in USB all night,in the morning i remove a battery,remove a SDcard put back batery,plug usb and it go,I replace infromation from the card with onother sdcard,flash the phone. 10x for the help,maybe now everything is ok

- the screen freeze on image and not respond on touch neiter button
-after 2-3 minutes phone temperature became very hot and screen again on freeze
- removed battery (for power off button not responding)
- insert battery
- no power up, no green LED with AV adaptet, no USB recognized
I'll trying to charge battery but i don't have a table battery chager.

Could you please repeat me what you did, since I didn't get the first part, what did you put on your router (what kind of router please)?
I've tried using my phone with another HD2 phone's battery which is working (and which also started with my own battery?!) but my own phone wouldn't start at all with the other battery...
The battery wasn't fully charged, but did it have to be, if so how long should I charge the battery with the cut USB cable for it to be charged enough please?!
TIA
P.S. I've tried a voltmeter on my battery and it said 4.14V (should it be 4V exactly?) and should I even try the cut USB charge trick again (since I've tried another phone's working battery)?

Ok if I understand you correctly you have tried your battery in a working HD2 and it worked. Then you tried the battery from the working HD2 in your device but your device still did not boot up. If this is correct I do not feel your battery is the problem, but still check the battery pins on your device to make sure none of them are not slightly bent and not making contact properly.
Also if you can provide more info on what you may have done to cause this or what happened when your device reached the state it is currently in. This info can help others and me help you better.

I have a similar problem.
The phone won't start, it gets to the white htc screen sometimes but quits within a fraction of a second.
This has been so since the first Android boot hung (I suspect I have not followed the steps accurately enough...). I have charged, decharged and recharged the battery using the suggested USB-cable technique, but this was of no aid so far, so it's not the battery. Pins and all's fine.
It's someone else's phone, too, so it would be rather unfortunate if I bricked it.
Are there any other common reasons for this behavior? Most tutorials rely on a PC connection, but as it does not recognize such a thing, that's a bit of a problem.

Finally the same problem here.
Battery status was about 70% and running smoothly (WinMO Custom Rom) since installed.Unlocked the Screen and tried to start programs.
The Icons were lightened up but nothing happened.Tried to softrestart...Nothing happened.
Removed and reinserted the Battery.
=> Not turning on.
-another fully charged Battery => nothing
-charging on Charger => nothing not even charging light
-plugged into (running) pc => nothing not even charging light
-5 hours in the fridge => nothing
-charging over night => nothing
Any hints ?
Thx for the goot work around here and greets from Germany !

[Q] black screen and white stripes (CM9)

Update4: (14.01.2012 1244): This method didn't work. I sent my Defy back to Amazon and they repaired it under warranty
They will send it back to me next week. It seems that it was a production failure.
Anyway, thank you very much for your help cengiran!
Hi Guys!
I do have a big problem with my Defy.
I updated the CM9 onto the newest version and had to activate my google-acc. I didnt finish the smartphone registration and put my Defy to the side. Today morning the battery was empty and I reloaded the battery. After that I turned the device on but the only thing it shows is a black screen with stripes (even in cwm and bootloader). Does anyone know how to fix my Defy??? The Defy boots completely but the screen remains crappy ;(
Please help me!!!
With best regards
HT
Edit1: (27.12. 1421): New day, same problem ;( Still found nothing helpful...
Update: (27.12. 1736): Flashed a new fixed sbf with RSD Lite. Still the same problem. Could it be a hardware problem??? LCD-Display broken or stuff like that? Didnt throw the phone through the room like others (^^);
Update2: (29.12. 0801): Error still remains... Is their anyone who had the same problem or who can help me? Do I have to replace my Defy? Might there be problems with Amazon (warranty) because of root and stuff like that?
Update3: (30.12. 2217): Now trying the tip by cengiran:
cengiran said:
hi there,
i have the same issue but not due to CM9 installation but due to hardware issue. judging by your writing, this has nothing to do with software and so hopefully this helps.
My screen is also black at boot with some part of it are stripes (and some bad white and blue square w/ noise) and looks like a broken LCD monitor.
This is due to hardware malfunction (probably your battery went bad) in my defy the battery have some water damage and somehow it screws up the voltage regulator or the grounding part, but does boot with the correct screen using some techniques on every boot.
Try this solutions:
1. completely discharge your battery, take it off, hold the phone power button for 30 seconds to make sure every power stored in phone is out. Put the battery back on and connect the charger while the phone is still off. DO NOT turn the phone on. Your screen will look all mess up when showing the green battery, wait until 3hours and take a look at your screen again. In my case, the screen showing the the battery charging image is clear again after i did this. - this is to make sure that your screen is actually okay. Try turning your phone now and see...if its still bad then go to step 2.
2. turn phone off, open the battery case. Connect phone to charger again without turning it on. The phone will do its regular boot up until showing you the battery icon again. when the battery icon is there, PULL the BATTERY out of the phone (the charger cable is still connected to the phone). the phone will reboot itself with the correct screen usually, if it doesnt boot itself, quickly pull charger cable and reconect it again (with the battery still detached from your phone).
mind you if you get to the okay screen, this will not boot your phone, this will bring you as far to the battery icon with a question mark (we know for sure is just battery issue now). regardless screen is okay or not, proceed to step 3.
3. turn off phone, battery out of the phone, and press the power button for 30 seconds. release power button and re-insert battery and boot. (usually still bad but this is to ground any left voltage in there). after it boots (with the bad screen, if the screen is okay then proceed to using your phone like usual) before the LED lights blinks (the 2nd.init lights) pull out battery, press the power button for 2 seconds, re- insert, and boot. repeat this as necessary until it boots with an okay screen.
tips:
battery empty is for step 1 only, steps 2 and 3 needs power form the battery.
You can actually go to step 3 if you wishes, but my experience is by using step 2, it will talke less retry until i boot with the okay screen (i need to do this everytime i restart the phone mind you, so its a daily thing) .
the LAST tip: there no rules of thumb on how many retries it needs, if you have been retrying for 20 minutes on step 3 with no avail, revert back to step 1 or 2 and retry step 3. If this is sill fails, then you might need to consider purchasing a new battery, or take it for a repair!
Im still waiting for my new battery, but now it only takes me 5-6 tries before it boots correctly, in the apst it took me 15 minutes of constantly retrying so be patient, but still need to set a line when to give up!

how does it go?
to completely discharge your battery is tricky...and actually not recommended because i heard our kind of battery should never went completely gone, it can mess up the battery capacity. i suggested it because thays what i did and in this case, battery cost much less then actual repair,,call it collateral if you will.
heres what i did to completly discharge it...after the phonse turned off automatically due to battery running out, it still have around 2% in it so reboot and enter 2ndinit/boot loader. let it stay there until the phone turned off on its own again. in 2nd init, the phone wont turn off screen so it will continue using whatever is left in the battery. keep n mind that even at very small amount of juice left, this process can takes up 2hrs or more.

...can't post a photo of the screen...
Update4: (14.01.2012 1244): This method didn't work. I sent my Defy back to Amazon and they repaired it under warranty
They will send it back to me next week. It seems that it was a production failure.
Anyway, thank you very much for your help cengiran!

hi there,
i have the same issue but not due to CM9 installation but due to hardware issue. judging by your writing, this has nothing to do with software and so hopefully this helps.
My screen is also black at boot with some part of it are stripes (and some bad white and blue square w/ noise) and looks like a broken LCD monitor.
This is due to hardware malfunction (probably your battery went bad) in my defy the battery have some water damage and somehow it screws up the voltage regulator or the grounding part, but does boot with the correct screen using some techniques on every boot.
Try this solutions:
1. completely discharge your battery, take it off, hold the phone power button for 30 seconds to make sure every power stored in phone is out. Put the battery back on and connect the charger while the phone is still off. DO NOT turn the phone on. Your screen will look all mess up when showing the green battery, wait until 3hours and take a look at your screen again. In my case, the screen showing the the battery charging image is clear again after i did this. - this is to make sure that your screen is actually okay. Try turning your phone now and see...if its still bad then go to step 2.
2. turn phone off, open the battery case. Connect phone to charger again without turning it on. The phone will do its regular boot up until showing you the battery icon again. when the battery icon is there, PULL the BATTERY out of the phone (the charger cable is still connected to the phone). the phone will reboot itself with the correct screen usually, if it doesnt boot itself, quickly pull charger cable and reconect it again (with the battery still detached from your phone).
mind you if you get to the okay screen, this will not boot your phone, this will bring you as far to the battery icon with a question mark (we know for sure is just battery issue now). regardless screen is okay or not, proceed to step 3.
3. turn off phone, battery out of the phone, and press the power button for 30 seconds. release power button and re-insert battery and boot. (usually still bad but this is to ground any left voltage in there). after it boots (with the bad screen, if the screen is okay then proceed to using your phone like usual) before the LED lights blinks (the 2nd.init lights) pull out battery, press the power button for 2 seconds, re- insert, and boot. repeat this as necessary until it boots with an okay screen.
tips:
battery empty is for step 1 only, steps 2 and 3 needs power form the battery.
You can actually go to step 3 if you wishes, but my experience is by using step 2, it will talke less retry until i boot with the okay screen (i need to do this everytime i restart the phone mind you, so its a daily thing) .
the LAST tip: there no rules of thumb on how many retries it needs, if you have been retrying for 20 minutes on step 3 with no avail, revert back to step 1 or 2 and retry step 3. If this is sill fails, then you might need to consider purchasing a new battery, or take it for a repair!
Im still waiting for my new battery, but now it only takes me 5-6 tries before it boots correctly, in the apst it took me 15 minutes of constantly retrying so be patient, but still need to set a line when to give up!
Hope this helps and good luck

Hi cengiran,
thank you very much for your help. I will try this immediately. The only problem I do have that my battery doesn't want to go empty XD
There are so many people who want their battery to last as long as possible and now I want to get it empty a quick as possible XD Irony
Since 26th December 1004 pm my Defy runs with one single battery charge XD I think thats a pretty good battery life for a smartphone ;D
If your tips don't work I will sent it back to Amazon and hopefully they send me a new one or repair my old one.
Thanks again and I will post if your method works.
With best regards

P.S. Amazing that this thread is the 1st Google search result for this problem XD

Finally! My battery is empty
Now I try your method and see what happens

Thanks a lot, a mix of these two works for me !
My problem arise after a month that I switched off defy for replacing it with a new smartphone (Xiaomi M2S).
I removed battery to force it to switch off, because I couldn't see anything.
I replaced the battery, I connected the phone to charger and after ten seconds (more or less) I removed the battery.
At this point I can see the Motorola logo. I've re-inserted the battery and it shows that it is at 97%.
For sure, the lcd is working
