[Q] No boot after downgrade from AOKP (ICS) to CM7.1 - EVO 4G Q&A, Help & Troubleshooting

I was running AOKP for a few days and I decided it wasn't going to work for me. So, I reboot into recovery, wipe everything and restore my CM7.1 backup. The CM 7.1 backup restores just fine. I boot the phone once to make sure it works and it does. I then immediately reboot into recovery so I can install gapps. Booting into recovery hangs for a minute so I pull the battery and try to boot into recovery. This is where the problem arrises. The phone doesn't boot into recovery unless it is plugged into the USB. After selecting the recovery option in the bootloader, the screen goes black, vibrates 4-5 times and the green LED flashes. Also, the phone will no longer boot into the CM7.1 backup. If I restart the phone, the white HTC EVO screen displays and then the same vibrate/screen/LED issue happens again.
Can someone point me to the right direction for fixing this?

HELP! Boot loop, cannot access recovery

Hello,
I was happily using CM7, and while reading through a Diablo III news page (hopefully it comes out soon ), my phone rebooted into a boot loop. Weird, but I figured at worst I would wipe data and reinstall a ROM. Unfortunately, I can't get into recovery any longer.
If I boot the phone normally, I see the white HTC splash screen for a few seconds, then it reboots. I can use HBOOT fine, but as soon as I try to reboot normally / boot into recovery / boot into Restore Factory Defaults, my phone will try to boot accordingly for a second, then reset. Let me clarify...
Pull and replace battery
Boot into HBOOT (volume down + power)
Select Recovery
Phone reboots and reaches CWM Recovery 3 for about 1/2 second, not long enough for me to click anything
Phone reboots into boot loop
I've used HBOOT to flash to CWM Recovery 3.0.0.8, downgraded to the stock radio, run the 2.2 RUU. I'm still running up against the same boot loop problem.
I wouldn't be surprised if it was a hardware problem, but I'm anxious to hear if anyone has ideas to try first. Additionally, is there any way to restore to S-ON through HBOOT in case I need to bring this into a Verizon store?
Thanks!

Boot loop with all SBF

So I recently flashed my phone to the newest MIUI. I decided to delete CWM for some stupid reason and now my phone won't boot up.
I figured I can just flash my old 2.2 SBF back in and redo everything. Well, it goes into infinite boot loop.
So now...
Battery won't charge (doesn't recognize the battery when plugged to charger)
Tried all different kinds of SBF and all of them end in infinite boot loop
Only thing my phone can do is bootloader. Recovery mode doesn't work either.
Any ideas?
what happens when you try to enter recovery?(power button + volume down)
if it shows android with exclamation mark then press vol up+vol down at the same time..then wipe everything and reboot.
Battery was too low (0%), won't boot into recovery.
I did the Mcgyver trick and got it going.
System wipe + 2.3.3 flash booted it back up. It can charge again now. Right now trying to get rooted and get MIUI running again.
This time I'm not touching the 2ndinitdefy.
Everything was running so well and I had to go and screw it all up.
it happens....
everyone learns from their experience
All the best

Cannot boot into rom.

For a while now I've been running a MIUI ROM without problems.
Today, the phone didn't want to wake up from sleep (tried using trackpad and power button).
I pulled the battery and started the phone back up but after the boot animation it went to black screen and wouldn't do anything from there.
I wiped cache and rebooted, went through the app checking but somewhere in the process crashed and went to black screen.
After several failed tries of pulling the battery and trying to reboot but only getting black screen, I did a full wipe and tried installing a new ROM but have not been able to boot into it.
According to the ROM installation everything went fine, but when I boot the phone up it starts trying to boot the MIUI boot animation then goes to black screen even though I did a full wipe and flashed a new ROM.
After doing various full wipes and sdcard formats, the phone doesn't seem to want to boot into anything even if I flash a rom, and recovery keeps loading up in Safe Mode due to a problem with /cache.
Any help would be greatly appreciated. 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?

Click to expand...
Click to collapse
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???

Phone shuts off and wont turn back on

I've had a CM11 Official Nightly installed on my phone for a couple weeks, and just today my phone started turning off, and when I try to turn it back on it just shows the Samsung logo for a few seconds, then flashes the CM11 logo, then the screen goes black. It does fully boot up when I pull the battery for a few minutes then turn it on again, but it only lasts for a couple minutes before shutting off again. It does the same thing when I try to boot into recovery (TWRP), it shows the Samsung logo with the boot recovery text, then shows the TWRP screen for a second, then shuts off again. Rarely it will boot into recovery. Any idea what the problem is or how to fix it?
I would try installing the latest version of Philz Touch for the d2lte to see if you can get into recovery and stay in recovery. I used to have twrp on my phone but it gave me problems when flashing ROMs.
Thanks, installed Philz Touch recovery via Odin, and got it to boot into recovery and installed CM11 and it seems to be working so far.
Good news. For future reference, I would load the Samsung Phone Info app from the playstore to confirm the bootloader and modem on your phone as some ROMs may require the latest bootloader and modem to function properly.
