[Q] HD2 not starting (Android Clk) - HD2 Android Q&A, Help & Troubleshooting and Genera

I know there are a lot of threads about a non-booting HD2 but I can't find any solution for my phone. That's why I am asking things again.
My phone was perfectly working when I went on my holiday two weeks ago. I have used it on a wifi hotspot and after that I left it in the safe. When i took it out after a few days (it has been on flightmode all the time) the phone was rebooting itself..
Too bad it didn't boot up my CLK android again. After trying this is what i can do with it:
-Take out the battery, replacing it. Hitting the power button there is a verry short vibration, after that a longer vibration, the HD2 bootscreen and then it starts CLK but stops with this last line [240] --suspend--
-With the phone on the charger that line is: [240] udc_start()
-With the phone on an USB connection i am able to enter fastboot and connect my phone, even installing is possible.
But my phone won't go in recovery (holding the home button while powering on) an won't go in bootloader (vol down)
Seems to me there is a problem with my hardware keys. Not shure, but should they light up when I am powering on my device?
Hopefully someone could help!

Have u try reflash the cLK and the rom?

I can't flash clk or rom, can't enter bootloader..

if you can get fastboot have you tried flashing the recovery again ?

Yup, but still unable to enter Recovery

Wait, you say you cant enter tri color bootloader, dont you? this cant be anything good, sounds like a brick. If you can, I advise task 29 and then reflash

I can't enter tri-color screen, because it seems like my hardware buttons are not functioning (vol-down especially). So task 29 won't work because it is impossible to connect..
Please can anyone tell if my hardware keys should light up when starting my HD2.

OK.. Little update.
I've found out that if I leave my HD2 on power for a couple of hours (no battery in), and after replacing the battery I am able to start into tri-color bootloader. So I did a task29 anf flashed the CLK partition layout and in fastboot i've installed recovery. To bad, I am now unable to enter recovery! Will try again in a few hours, hopefully same problem as with the bootloader. But still seems there is a problem overall. So maybe i have to get a new phone in the short future (Sensation that is)

oh guys, same problem here, i'm unable to enter bootloader and recovery, only fastboot works.. any idea about that?

From described above, I think what you did would not damage the SPL, which loads the fastboot...
Maybe there's a hardware problem
Anyway, try fastboot again! (long press back and then power)
and there seems to be a way to save your phone through ddms (please google it. it is mentioned in one of the threads(
volume Down + power , Home + Power , Back + power.
i press this keys to power up.
it just have a vibrate and the HTC Magic screen then stop........
i wait about 30 min nothing happen.
i need to pull the battery out to stop it.
can't use DDMS cos My windowXP can't see USB device when i connect magic to window.
i don't know how to do.
thankyou for your reply.
if SPL not being flashed (no damage), then u should able to enter "fastboot"
i don't know what i done.
just can't hboot and fastboot now.
You have to hold both buttons (POWER + BACK for fastboot) until the flash screen shows up.

may be i need pick Magic back to repair center.
but i still want to repair by my hand.
thank's for any reply.!!!
This is a long shot, but I had something similar happen to me when I upgraded my SPL. Try renaming the latest spl as update.zip and putting it on your SD card.

What should one do if flashing a new SPL doesn't work?
Exactly the same problem.
I have returned the phone to 3. they gave me a new one.
my problem occurred after I flash a SPL into the phone.
so, must be the SPL making the problem.
Maybe you have to send it to repair.
****ed

My Magic's bootloader is
PVT 32 A, CPLD-12, Boot with Hami
Hboot 1.33.0009
After I flash the hboot with this post then reboot,Same thing happend。
But I Figured Out Somehow,You can still enter the fastboot mode,but not with the original view。
The fastboot Mode shows A Red line words "fastboot usb" at the upper-left corner,and the logo still Hami。
What I did is Volume Down+Power,Then Try to press Other Bottom ( I Don't know Which Bottom Exactly.)。
Sorry For My Poor English。
Mine is also bricked. Same story, I flashed the spl and it just rebooted to the htc screen and will not recover from it. I get no sort of red flashboot menu. It's completely unresponsive on all levels. Such a shame, I'm worried about this being a design fault with the magic. Perhaps there's a line of models with this problem. I can still choose a different phone altogether if I bring it back.
I REALLY like the look and feel of this phone... but I don't want to brick a second one.

I got a second one from "3". I would recommend u not to touch the spl again.
Sad as it may be to brick a phone, I don't see failure as a reason for giving up. I haven't successfully modded my phone yet, and that bothers me. I'll do it, and I'll succeed. If not, I'll go back there and replace it again
I WILL do it right.
Anyway, enough of the power speech.

Maybe a solution
Hi
I had my phone end up in a state in which it would immedialtely show a black screen with HTC logo and do nothing else - even when just inserting the battery. The whole thing seemed pretty stuck
But then I found out that holding "back" and "power" down before and while inserting the battery did the trick - then the phone booted into the fastboot mode and I could start revovering it using some appropriate recovery image and an update.zip that I had placed on the SD card in advance.
This has helped me a couple of times since then
Seems to me that as long as you have not messed up the SPL, there are ways of recovering.
Hope this might help.
well, I don't have a chance to test your method.
can anyone, whose phone is bricked, try !!holding "back" and "power" down before and while inserting the battery!!

Magldr 1.12 instalation problem

Hello,
I wanted to ask if someone clashed with problem like that and knows how to solve it. I had 1.66 rom eastern euope and installed 2.08hspl, tried to install latest magldr and I am guessing problem occured because I didnt installed latest radio. Now when I am turning on the phone it shows white screen and green logo and stuck. Tried turning of the phone and holding - volume button when turning on that didnt make any difference can someone help me to revive my phone ?
So you tried to get into bootloader, but the thing is you have to try harder.
Bootloader should work just fine.
So again, turn of your phone. while the phone is turned off, keep the vol down, and press the power button.Release the power button, but keep the vol down pressed.
You can try the other way: hold the vol down pressed and reset the phone(red button on the back).
If you want to use the SD card method to flash something you still have to enter the bootloader, so you must keep trying.
Forgot to ask: did you manage to enter the bootloader or not, cause you only said it did not make any difference????.What does that mean?
I already trying to enter bootloader for the five hours, so I guess it's impossible, also tried that thing with red button it didnt load up that bootloader screen. The thing is that holding volume key down didn't work for me before to get into bootloader even when the phone was ok but it did install all roms which I tried so I didnt think that this would be problem either apparantely it is... Maybe youu have some other suggestions how to fix it ?
If you can make the pc recognize the HD2 then you can flash anything.
But i think that this is only possible in bootloader or windows or android.
So this is a problem.
No ideea for now.
Anyone help???
But you *do* push both vol. down and power buttons and keep them pushed until the screen turns on, don´t you?
I didn´t get into the bootloader as long as I didn´t kept both buttons pushed long enough... had to learn the "timing" kind of...

Strange brick

After an eng-off attempemt my dhd became in a strange brick situation: no turn on if I press power button but if I remove the battery for 5 minutes it turn on with a long vibration in the boot. When I power off the phone the brick condition return. Please help me
CAn you hold the volume button down and power on to get into the bootloader?
Nothing happened...Only if i remove the battery it power on. I suppose the bootloader was corrupted, you know how to reflash it?
I have also try to use this http://forum.xda-developers.com/showthread.php?t=905003 to flash another hboot, succesfully but after the reboot another brick...the phone power on only after 5 minute battery off. No solution found...
Nobody can help me? From my latest test with terminal I discover that i can't write hboot, why? Damaged? please help me
Had you achieved s-off? where and when did it all fall apart? You dont have a brick as it will respond to some input, even if it's only dragging battery out and replacing it. But I suspect the easiest root if you can't persuade it to boot at all is going to be attempting a warranty repair with HTC just play dumb.
I don't know if I have got the s-off because I can't enter in hboot, if is possible I prefer to avoid the warranty repair, in Italy they offer a very poor service (my dhd was already been sent 3 times unsuccessfully for the GPS)
if there is fastboot and you can't overwrite the bootloader you might have some issues with flashing a recovery version. You may want to try running the RUU software but i doubt this will help. I know it is difficult to kill an android but i think a corrupt boot partition might be the death of a smartphone.
When you load the battery back into the phone next time, press the power button, wait for the white screen to appear and immediately hold vol- might get you into the bootloader.

I have already tried to push the volume button in the power on but the dhd doesn't enter in bootloader.
I have tried a RUU but it give me an error, maybe an incorrect version? Can you send me a link?
I have discover that if fastboot is active I have no brick in start up, but obviously I cannot enter in recovery
adb is working but brick if a try a reboot command, is possible to use adb (without a reboot) to fix the boot?
WOW!!! after another battery pull out and 5 minutes pulling down volume dhd enter in hboot but it is stuck and doesn't react to input.........
I didn't understand, when you power it up with battery pulling, you can use it normally, or not?
Sent from my HTC Desire HD using XDA App
yes but i must wait 5 minutes without battery and other 5 minutes with, after this the phone power on automatically with a strange long vibration (1/2 minutes) but it is the only way that I have found
If you can get into hboot, and you issue the command fastboot devices (via terminal on your pc) does it list your DHD?
Sent from my Desire HD
if i try from pc no response, command fastboot devices get nothing and the hboot is very slowly and stuck on reboot command
If the PC sees the phone when is connected, try to run a RUU corespondent with your area http://www.filefactory.com/f/efa28fefafc4af9c/
Edit: I don't know if is the same situation but I read here that the devices shipped with Gingerbread cannot Eng S-OFF.
the pc doesen't see the dhd. could I try to flash the PD98IMG.zip with the hboot?
I could start with the hboot the zip indicated above, but then freeze the update process in step 9 "TP" what is it? The hboot indicate program firmware image

[Q] Motorola APX ATRIX 4g does not go

Motorola ATRIX 4g phone, and ATT is discharged and the battery during the update.
Now it is switched on, type "Failed to boot Nvflash 0x1000 Entering recovery mode."
APX Nvflash tried to start but windows 7 does not recognize the device manager did not even know.
What should I do? This field may improve through usb?
thank you
depending on where your phone ran out battery it may be a brick, or you may be able to recover it...
Take the battery out and put it back, then hold Volume down and boot the phone. IF you see "fastboot" (Press the up key) and hope you boot into fastboot mode
You can also press down to see if you can get to RSD....
If you can get to these 2 then you can recover your phone...If it gets stuck on starting nvflash and doesn't give you a menu then your phone is bricked.
No, that won´t work as he is stuck with an empty battery and if the phone won´t boot the battery won´t charge. Catch 22
Either charge the battery in your backup Atrix
or search for the "McGyver method", which means sacrificing a USB cable. Oh well...
What's wrong...........

Battery charged 80% of the vol up + power does not respond to the power + vol down to either the Irish problem APX installed but nvflash RCM 0x4 version.
Could not be fixed some way because it would be urgent!
Non-root your phone and locked the bootloader, RSD does not come in!
noob troubleshooting
OK we all have to try read and fail. Atrix 4g with 2.3.6 Unlocked and rom manager, titanium backup attrix 2 boot strap. What I did. did search and found this great reading rom. Followed all the info. Reboot great. Works. OK all but it will not access data other than in wifi. email, browers both say no connection. I have gone back and tried to clear all data and load other ROM. Can't get any of the ROMS. to load. either through update.zip or named.zip. Here's the stupid part. It was a victory ROM v2.0 it was for a samsung captivate. the link brought me across and I didn't look at the top to see if it was a dang attrix. Any idea on which how to get at least the data to work other then the wifi? I can access the recovery mode and it will reload the VictoryROM but nothing else. As F Gump says Stupid is ..as stupid does.
appreciated

I don't understand half of the things you wrote...
If you hold vol down and press power...Does your phone boot and go into fastboot mode? Yes/No (It will say "fastboot" and pressing Vol Down will cycle other options....Then you have to press Vol Up to enter into Fastboot mode)
If it's "NO" then when it does boot do you have any other options besides NvFlash? If yes then you can recover, if no then your phone is bricked.
Victory, and A2 Bootstrap? wont work on a 4G. Either you are in the wrong forum or you have managed to put A2 tools on a 4G, which shouldn't work, and apparently doesnt.
If you can get to CWM, put a copy of CM7 on the sd card, CWM flash it. clear caches. etc.
Hope it helps

Zuk Z1 Soft Brick

Dear XDA friends,
i always hoped not to be one of those guys, who f****d up their phones to the point of no return. I really screwed up this time. Well, here I'am writing you about my screw up.
I unlocked, rooted, flashed and repaired all kinds of android phones in the past years, never without problems, but I could always fix it somehow. Not so much this time.
Now I'm stuck at Bootscreen with the Zuk logo. I even have problems pinging the phone via ADB.
Sorry for my noobish question guys. Any help would be much appreciated.

I got this translated from a chinese website:
For fastboot mode:
The phone turned off; keep the connection turned off the data cable to the computer, press: [volume down key] [Power Key] waiting to enter the fastboot mode.
For recovery:
Turn off the device
Press and hold Power key
When vibrates Volume UP key + Volume Down key about 10 seconds
Release all key when Android logo appear then you will see Android System Recovery
Use Volume key to select Menu
Use Power key to Confirm
Can you enter any of these 2 modes?

Does anyone know where can i find the scatter file , MTK ROM for zuk z1, i would like to try the SP flasher tool. Or if anyone have any idea how to solve this issue on lenovo zuk z1,pls. help.tnx
Can y get to fastboot ?
im facing the same problem after i had the stupid idea to lock the bootloader again, before that i flashed the phone successfully with the cm mod recovery and cm 13.
Has anyone found a solution to this ? or do i have to send it back ?
What i did exactly :
I locked the bootloader again and just to test it i tried flashing the recovery again , ofcourse it didn't work which was what i wanted.
Afterwards i rebootet the bootloader with sudo fastboot -i 0x2b4c reboot
now im stuck in a bootloop that i cant even stop , in other words i cant turn my phone off nor can i access the recovery or fastboot
Im feeling so stupid that i locked it again .... i will try to get into recovery after my phone ran out of battery but so far it looks quite bad...does anyone know if i will get a replacement even though it was my fault ? ( i don't need to say that it was my fault ..and the bootloader is now locked again )
UPDATE::
I found a promising thread about this problem, i will report back here if i was successful.

Please help , same problem
I am facing same issue too from 2 days. I didnt even try to flash custom roms or play with boot loader or recovery or anything. All of a sudden my phone entered boot loop. After two three bootloops phone is entering "12 apps optimized of 230 apps" mode, completing optimizing all apps and then failing to start apps, entering boot loop again.
Effort made so far to fix -
1) Went to recovery and cleared cache - didnt work
2) Went to recovery and did factory reset - factory reset did happen but boot loop didnt stop, I realized that factory reset happened because now its saying optimizing 120 apps instead of my 230 apps during the bootloop.
3) Went to recovery, Entered fast boot mode but not able to connect to PC. Fastboot devices is not showing anything. I made sure proper driver is installed after researching on XDA.
4) Went to recovery, Tried "Install update". Didnt install anything but browsed through folder structure and realized my data is intact
It will be great if someone can help me atleast recover my data before I handover phone to service center for fixing boot loop issue.
Same problem

Sorry For Re-posting Here. This is Solution
Why this is happening ?
Due to Dirty Flash from Zui or from COS/CMOD but suddenly Bootloader gets locked
May be Due to Some Custom Rom which only works with Old Bootloader ( And you are on latest 2.5 Zui QPST Flash)
Reasons are many. I also did same mistake. I flashed ZUI 2.5 using QPST then unlock bootloader using official site installed twrp after wiping cache system and data , Installed Lineage 0S JAN Build then without rebooting installed Lineage Nightly build (Latest) with Gapps After rebooting Phone goes into Restart endless loop on ZUK Logo. Blink and Vibrate .. After 1hr I figured it out but its 5am So slept.
HOW TO FIX ENDLESS REBOOT ON ZUK Logo ?
-> Identity vibrate patterns (Press Power Key I count 6- 7 Vibration pattern ) After long Vibrate immediately remove finger from power key.
->Once its Done (Phone completely off)
Download QPST and Official COS QPST from this Link https://goo.gl/InWQji OR https://goo.gl/iqrnlI (I am personally Very Thankful to D tech Terminal for posting Wonderful video on Youtube https://www.youtube.com/watch?v=4Dl6JkAVpuM
<- please install all drivers and software.->) @ankurpandeyvns Thanks bro.
Main Task is here and Lots of Patience is required and You also need to be very Blazing fast to achieve this.
-Once you download and install Qpst open Qfil
-Now press Volume Up only and connect USB (Just press POWER KEY only for 1 sec It will vibrate and connect)
-Without waiting hit Download button.
-Voila It will start flashing your phone again and Hence Your phone is now Revive..
-Once Revive You can use it to again flash custom Rom or stick to stock Rom if you want.
Keep Flashing !!!
Patience is Key here. And Don't lose hope.
:good:
EDITED:
While connecting to pc and by pressing Volume key you also need to press Power key for 1 sec or 2 sec until it gets detected. Thanks addicted777 (for tip)
