[Help] How to prevent the phone from auto booting?

Hi all,
I dunno if any of my steps goes wrong, but my phone keeps auto booting even i dont push the RED button, even i remove the battery and put it back again, it keeps auto booting so i cant choose fastboot mode or recovery mode.
All i did is:
- fastboot boot recovery-RAv1.2.1H.img
- choose Apply sdcard:choose zip and select update.Engineering-SPL-HBOOT-1.33.2004-signed.zip
Is it bricked? Could anyone help?
Thanks in advance.
1st off wrong section man you gotta take this to general...
2nd try press and hold home and power see if you go into recovery...if you do then your not bricked.
sorry i'll move this to general
so did you get it to work?
no i cant boot to recovery or fastboot, it just keep showing the htc splash screen, i'll take it to the htc care guys to see if they could help me. thanks btw
is your phone plugged into your PC when this happens? Dumb I know but when my phone is plugged into my pc it autoboots
Yes i realized it afterwards, i just unplug the usb cable and it stops auto-booting, but i cant reach the recovery and fastboot afterwards. Anyway, i've already take it to the customer service and seems that they have way to flush back all the software part and i could have my magic 3 days later
Actually i just wonder which step is wrong for me, should i root the spl before flashing a new one? or i should just skip it? i wanted to know this more

[Q] I screwed up my brightness.

I wad messing around with a widget and lowered the brightness on the screen to much and the screen dosent come on where I can see the on screen buttons. Is there any way to reset the brightness by remote or reset the whole phone by the buttons on the phone. The phone is rooted.
These threads *might* help...

I have tried everythingto get it to come back. those posts dont help me much in my problem. i have tried the odin flash and tried restoring the sysmtem diretory but still no screen i dont know if i need to do the kernel and the recovery part of odin. this sucks the most because where i am at this thanksgiving i have no internet access.
I actually just did this to my phone a week back.. this is how I got it back. I started to call my own phone with someone elses phone and once out of every about 5 calls my screen would turn on for a second so I kept doing that until it stayed on long enough for me to go and change the brightness back. lol I know its not a full proof fix but thats what did it for me..
IF you have a nandroid backup, you can boot into recovery and restore that backup. That's what I did when it happened to me.
I wish they'd get this problem fixed. Most apps that adjust brightness fixed it, but apparently not all of them.
I never made a backup of the system. The the call idea I just made ten calls to my phone and no luck any other ideas.
i tried put my phone back in stock factory reset using odin. the threads are located under development and its pinned
or
u can just get a replacement if ur under return policy
I tried the stock reset to factory with Odin but my screen still disentangle come on.
i recall someone saying that flashing Clockworkmod Recovery fixed this for them
Now that im back home from vacation and have internet i can figure it out. Like i said i tried the stock rom and no go then i tried the Clockworkmod and no go, i cant use the rom manager because i cant see the screen to use it. as for the update.zip in the root of the sdcard (/sdcard) i did that and held volume up when i turned on the phone and went to run the update.zip from the recovery menu and it says it cant find it.
Did you install Clockwork with Odin?
Yes and im going to try it again now that im at home.
with clockwork i can get in but as i try to sign into google the screen goes black and i cant get it to turn back on.
I can get it to start up in the recovery menu choose to wipe data/factory reset, then restart. it starts up but screen dosent come on. plug it into my computer screen comes on try to get to settings and shuts off and after to start over again.
Would it be possible to dump my wifes phone rom to the computer and use that to start off with or will that screw everything up.
Maybe try this?

After playing for two hours I finally got it to work.what was happening was the phone will go to sleep and I couldn't unlock it after the screen shutoff. But I kept the screen alive long enough to reset the brightness.
Now the big problem is I can't log into my Google account, I can't do it though wiring or 3g any ideas.

[Q] HTC Wildfire bricked? need help /will give reward

hello i just wanted to see if i still could get help with my useless device
Ok so yesterday ive rooted the phone and today i tried to install cyanogen mod 7 rom
i used rom utility which i ve downlaoded from android marketplace
now sometimes my phone boots and gets to the logo loop
ive heard that clearing cache and settings would work but i cant access these menus as my hboot is not reacting to my key presses , i tried to reflash the phone but nothing came with success.
I used android sdk and RUU but nothing with success .
maybe anyone would teamview me or give me step by step tutorial how to get this phone alive again would be appreciated
You will be rewarded
You rooted the Phone with a App from the Market?
You need if your HBoot is lower then 1.* the unrEVOked Tool.
If its 1.* there is no way to flash it.
Okay, maybe it worked with yout root app from the market, dunno, but i dont think so.
So you cant access while pressing volume down (keep holding) and switching on the phone the bootmanager? oO thats no good.
The Logo will stay up to "15minutes (<-?)" after flashing a new Rom. In this time its possible, that you Phone restarts automaticly. its normal. Switch it on an wait up to an half hour. If it keep staying in the boot sequence while showing the logo you got a problem .
I think there isnt a more unsave way than a "Flash by teamviewer". You have also pay attention to the phone while flashing. on TV you cant keep an eye on it.
But how can you reflash your phone without getting access to the bootmanager/ HBoot? I think you habe to access the clockwork to flash cm7 *thinking*.
If u nowhow to use adb try n get a adb logcat if possible
Sent from my HTC Wildfire using XDA App
Hi borris and daddyspud thanks for your reply ,i cant move around in hboot ,my hboot version i 0.80.0003
Ive rooted it using unrevoked with clockwork mod on it.
now even when i get it to boot it just loops in cyanogen animation,should i leave it for 15 minutes to do its thing?
also im new to this so i dont know anything about sdk and adb,all i did is saw the tutorials using it ,so i thought i would use it just to give it a go
HBoot 0.8 is rootable, so its okay.
If there is still an animation while you see the CM Logo everything is fine.
If it freeze for some minutes is there a problem. The Animation shows you "i am working / installing".
Yes, let him do his thing for some Minutes.
I think everting should be okay and after some minutes it will work like normal.
It reboots sometimes it self, but this is also okay.
I dont know... does the new CM7 also install a new HBoot? So its possible why you cant move around in it.
Do you wait about 10 seconds before you try to move around in it? Because in the first seconds it looks like it freezed an then it start a test or something. this takes about 10seconds then you can use it.
Its not bricked if its turning on.
Can you get into recovery? If you can try flashing the 4.1 kernel.
If that doesnt help, go into recovery and do a full wipe. Clear cache and dalvik, and under partitions menu format everything except SD card. Then flash CM7, then the 4.1 kernel
Remember first boot will take 10-15 minutes. Be patient. If youve done everything right you shouldnt have any problems
Hi and thanks for cooperation ,i left my phone on cyanogen animation for an hour and nothing is happening just animation loop constantly.
I've just tried hboot and it searches for the PC 49 DIAG and says not found after that it freezes and i cant use any menu navigation buttons . in hbot and fastboot.
I dont even know what to do next
Much help appreciated guys
oO
thats weird.
the PC49DIAG is a part of the rom it self. So i think you have to try to re-flash it. Did you try it with or without a goldcard?
before you flash your phone whipe ALL datas on it!!!
If i start in bootloader mode i get also all the "missing" errors but i can still use the vol up/down buttons to navigate around.
That should help.
I think you did something wrong while flashing.
the root failed?
you got an error while flashing?
goldcard?
Try to flash a RUU from shipped roms. DONT flash a Froyo rom, you will get the HBoot 1.* if you do this.
Recoverymode doesnt work in the hboot?
If you try recoverymode you will get a blackscreen with an triangle.
most say "press the power button" to enter the recovery mode. if this doesnt work press the "volum up button (hold it) then the power button" this should enter recovery mode.
**EDIT**
http://shipped-roms.com/index.php?category=android&model=Buzz use a www-rom its without a branding. and use a RUU rom.. and pls dont use a froyo rom. after flashing this your root is gone i think but your phone will be alive again.
dont try the cm7 this time. use a stock rom.
is it alive again?
i talked today to someone who hat exactly the same problem like you.
it was simple to fix the problem... he (you also?) didnt
whipe the phone before he flashed the cm7. thats why it wont stop looping
in the cm7 animation.
after whiping and reflashing everything was fine.
... did you whipe it b4 flashing?

[Q] How to reboot into recovery?

I rooted my G2 about two months ago. I'm currently using MIUI, not the latest but the one before it. Somehow, my phone got turned off and when I tried to turn it back on, it was stuck in a bootloop. I have a custom recovery image so I don't know if that affects anything. I tried to reboot into recovery by pressing volume down and power, nothing happened. I then did volume up and power. It vibrated three times and the orange light started flashing. I pulled the battery and now when I try to turn it on, nothing happens. So how do I reboot into recovery and so I can restore my backup? Any help/suggestions would be greatly appreciated.
Never pull the battery during something like that. It sounds like your bricked. Someone else confirm?
I don't think it's bricked. I plugged it up and then Clockwork came up so I selected reboot now. Clockwork came up again so I tried to restore my latest backup and the screen went black. I'm going to let it charge and then give it another try.
Ok good. That's lucky because whenever you pull on a boot like that, it usually bricks. If you have the option, try to re-flash your ROM. Maybe even try stock. If you were getting a black screen, it's most likely you flashed incorrectly.
Ok, I was able to boot into recovery and now I'm restoring my backup. I don't think I had a custom recovery image with this one so hopefully I won't get stuck in a bootloop. When you say stock, do you mean before I flashed MIUI (it was the first rom I flashed)? Thank you for your suggestions and all of your help.
first install adb on you PC, it helps a lot in these kind of cases.
1. try "adb logcat", it would tell you about what's going on in your machine.
2. once you get your adb working, try "adb reboot recovery" to see if it could boot your phone in recovery.
3. if after doing everything you fail to boot either your phone or in recovery then try using PC10IMG to boot a stock rom and then re-root your phone.
I got it back working. For some reason, I'm just starting to think that it needed charging (the battery had been out for about a day or two). I do have adb installed and configured on my computer since I needed it to root. Thank you for your suggestions, I will definitely rember them if this happens again.
lol of course when you get black screen and led blnking means your battery begging for juice, you're lucky that when the phone booted back in recovery and you tried to restore a backup the phone went off before actually starting to restore, that would've bricked your phone
DO NOT FLASH ANYTHING WITHOUT AT LEAST 40% OF JUICE LEFT

Stuck in bootloop, any way to recover?

My phone randomly rebooted today and now i'm stuck in a bootloop. not took a backup in ages and I have quite a bit of data that I don't wanna lose. is there any possible way to fix this? I believe a dirty flash should at least allow me to get back into the system and let me back stuff up but I'm not sure which custom firmware i'm on its been that long. is there any possible way to find this out from bootloader or recovery mode?

Click to expand...
Click to collapse
You cannot read out which rom you have from recovery or bootloader. Is your bootloader locked? Do you have twrp? Which device?
You can try to power off your phone by pressing the power button for 2 minutes and then start it. Also powering off and charging it to 100% can help.
Hello, I made a wipe cache in TWRP and then restart by pressing the volume up until the system starts
Good luck to you
