My phone won't boot - G2 and Desire Z Q&A, Help & Troubleshooting

I was on Insertcoin 1.4 rom, and went to CWM to install new kernel with fm radio. I wiped cache and dalvik, but didn't flash the kernel because I realized that there was two of them, so I wanted to reboot to check which is good but I stuck on bootloop. I took out battery, and rebooted again but still bootlooped. So I wiped with SuperWipe+ and installed rom again. It booted but when I was installing apps from market it freezed. I took out battery and turned on but it stayed on splash screen and did not go to bootanimation. I took out battery 2nd time and booted into recovery. It was showing some errors but it booted. I wiped and installed again, but it was still stuck on splash for a long time. I pulled out battery last time but now it don't even boot into recovery.. Also when i connect to charger amber LED doesn't turn on.. What I can do? I need quick help please.

Also when I connect it to usb it is detected as QHSUSB_DLOAD

Stuck on boot screen.

Went into recovery and wiped data, cache, dalvik then went to install Fresh 3.4.0.1. It was done installing and I gave it a reboot. At first I thought it was just the first time installing a rom that was making it take forever to boot up, but I fell asleep and just woke up, and that definitely wasn't the problem. It's still on the boot screen with the white background and black htc EVO 4G. I haven't been able to get into bootloader so far.
Any ideas?

I had a similar problem once. I would just get stuck at the splash screen no matter if i tried going into recovery or just normally booting up. What fixed it for me was to just take the battery out and leave it out for 5 minutes. Try putting it back in, booting into bootloader, then into recovery. From there try wiping everything and then installing Fresh again.
Also, make sure you are using Amon_RA recovery, as it correctly wipes everything.
yea try that what he said. take the battery n try it one more time n see if that works

[Q] CWM Recovery very slow all of a sudden

Hi Folks,
Was running ZYGOT3 2.0 and Franco #6 for last week or so, with no major issues.
Had a freeze-up after a phone call this morning, figured that maybe I was undervolting too aggressively, and didn't think much of it. Pulled battery, replaced battery, restarted phone, phone hung at Google logo.
Pulled battery again, rebooted to bootloader, entered CWM recovery no problem. Figured I'd reflash the kernel if my phone wasn't booting past the Google logo due to the undervolt settings. When I went to choose zip from SDCARD - the screen went black other than the CWM version and logo, and my folder list never appeared at the top of the screen.
Pulled battery, tried again, same result.
Pulled battery, this time went to advanced menu - wiped dalvik cache no problem.
went back to main screen to try to wipe cache again...and it hung again. Got distracted, came back to phone like 5 minutes later, and CWM had finally responded and was showing me the option to wipe cache.
So I was able to reflash Franco #6 and boot the phone back up. Then I just downloaded Franco #7 kernel - rebooted to CWM Recovery to install - and noticed that the CWM is again very sluggish. It seems that I need to wait anywhere from 30 seconds to over a minute before it responds to even a simple command, such as to show me the list of files & folders.
Any ideas folks?
Thanks!

[Q] HTC Desire HD boots but black screen afterwards

So I have a rooted HTC desire HD with Jellytime on it. All was working great till recently when it would shut down by itself. Today after I wanted to test a new boot screen from Rom toolkit I restarted it and while the boot screen worked great after it finished I see a black screen (backlit so I know its on). I tried going to the bootloader but after I try to go to wipe cache for example it restarts by itself and it gets stuck after the boot screen... Any ideas?
ok an update seems that if I go to the recovery via down button and power it lets me do actions. All this time I went to recovery mode when phone was shut down and plugged into a power source. I did a wipe cache and now it says android is upgrading and now it finished saying starting apps. Hope it didnt get stuck there because it keeps doin the cycle animation but doesn't do anything else.. I ll leave it be for a bit like this... :/ Had to restart it by removing the battery after 20 minutes... same problem as before still...
another update... just before it goes to a black screen when the boot screen finishes an orange light appears just briefly (where the green light appears when it charges)
Wipe everything (system data cache) and install a stock-ish ROM. What happens?

I flashed the rom again and wiped data and all seem to be ok now. I ll update this because I saw many people have similar problems... thanks in advance for any help!
Have the same problem.
I bought this with the problem that it keeps rebooting all the time.
I unlock the bootloader with htcdev,root with Easy Ace Tool,flashed the new cyanogenmod 11,
but did the same .
At least 3-4 rebooting before open normally.
I said that it must be ROM issue and flashed the KK-LegacyCarbon-4.4.
Did the things should be...flash the ROM and then the boo.img separately.
Now i have black screen and the only screen i am able to get is bootloader and the recovery 4EXT.
I reflased cyanogenmod back but nothing happened,any thoughts???

[Q] Looping Xperia logo

I was trying to install AuroraPlay 1.1, everything was going fine, i unlocked my bootloader, installed doomkernel, booted it up and it was fine until then. Then i followed the next installation steps (factory reset, format system, and flashed the rom, did it all on Clockwork mod) and now the Xperia logo keeps looping. I can't enter recovery, the phone doesn't vibrate like it did before on the doomkernel screen and no matter what i press it just goes to the logo again
I'm pretty new to all this so i suppose i just made a common stupid mistake. Flashtool seems to still recognize my phone when i connect it in flash mode, but not for long, it disconnects itself and reconnects again but not in flash mode. Can i save my phone?
After removing the battery many times, and trying again and again, it booted into AuroraPlay
Everything looked normal, so i turned it off and on again to see if it was fixed, but it's looping again, and i still can't acess recovery
I can't think of anything i did differently when it booted successfully
Start from begining again:
-flash stock firmware and see does it boot up
-reflash doom kernel again, if you can enter fastboot mode (hold search when pluging in usb)
-boot rom again, to see if stock rom can boot up with doomlord kernel
-if you can, reset to recovery(keep pressing back button), format data and system and install Aurora again
If you manage to boot to (any) rom, check your sd card for errors, if any...
Around half an hour after my last post, i left my xperia looping for like 10 minutes to see if anything changed, then took out the battery and booted it up again
this time i managed to go into recovery, but didnt want to flash everything again so i just applied the doomkernel v14 wifi fix that i couldnt apply before
it then booted into the rom normally and i've been using it since without a problem
kinda afraid to reboot though

[Q] JellyTime gets stuck on bootanimation

Hi, I have been running JellyTime 4.2 R11 for few weeks now on my S-OFF Desire HD.
Today, I noticed that the light was blinking and battery was low 6%, so I decided to put it into charger, and somehow when I connected it soon I accidently disconnected the charger, and when I put it back, the phone probably crashed or something, since it went black and the white screen with HTC logo appeared and it started to boot again. Now, JellyTime tries to boot, the bootanimation goes fine for sometime but then it gets stuck after "playing" the bootanimation for a while, nothing happens, even if I wait 5 minutes, it's stuck, bootanimation is frozen, no matter do I have the charger connected or not.
So, is there anything I could do, or is reflashing the only solution? I did full wipe when I flashed the ROM.
If you need more information, sure, just ask.
You could try dirty flashing, but if that doesn't work you'll have to reflash.

Thanks for the tip, but it didn't help, gets stuck still on bootanimation.
Time to full wipe and flash it again then. Wipe&FlashTime
Happened to me a few times. I suggest a battery pull before anything else. Seems stupid. But it can work in some cases

I did battery pull several times considering that the phone refused to shutdown even when holding the power button for 10 secs, so battery pull was needed every time.
Anyway, it's now running fine when I reflashed.

I have the same problem since a crash on opening the outlook-email App (JellyTime 4.2 R9).
I found, that the "data" partition causes the trouble when booting. Formating the "data" partition with "4ext recovery" fixes boot-freezing. But this is not an option for me as my last (working) backup is a couple of months ago (yes, I know - should backup more frequently...).
I was able to backup the up-to-date "data" partition (with 4ext recovery) but when restoring it (even on an fully wiped and updated system) boot sequence freezes again.
Any ideas???
Many thanks!
Solved the problem with the data-backup. Instead of restoring complete partition the APP "AppExtractor" works fine for restoring data of the partition backuped.
For now, system runs perfectly.
Conclusion:
If system hangs in Boot-Animation use Recovery for backup of up-to-date system. Full wipe system and install ROM of your choise. After that restore SMS, contacts, etc. with "AppExtractor". Apps should be installed from PlayStore as far as possible. "AppExtractor" allows restoring of app, data+app, data.
