[Solved] Vol Up+Power - G2 and Desire Z Q&A, Help & Troubleshooting

I ran into this one day and then again today. I know vol down+power is hboot and vol down+trackpad+power is fast boot, so what is vol up+power?
When I did it the phone vibrated 2 or 3 times and the orange LED started flashing. It wouldn't power on, fastboot, hboot, nothing until I pulled the battery (with it unplugged). So what exactly is it doing when I press that combo?
Just curious.

The thought on what that might be is an unknown utility to communicate with the qualcom chip set, no ones really sure how to use it or what it can be used for, but it only becomes active if you have radio S-off thru the use of GFree.

Well that's interesting... very interesting. Far beyond my level to even attempt to figure out how to utilize it if that's what it's actually doing. Still though, it would be neat to put some effort into messing with it to see what we can use it for, obviously only for those extremely knowledgeable or with large disposable incomes.

Its for factory jtag, problem solved
The G1 has something similar commonly refered to as "blue light mode" which is used to bring bricked G1's back from the dead.

Do we even have the JTAG printouts for the G2? Would be nice, then we could really mess with this phone since we could bring it back from the dead. Seems like we're only scratching the surface with this thing.

Vol up and power

I guess I accidentally held volume up and power instead of vol down and power. My phone vibrated 5 times (3 times?) and the green light came on, I think. Anyway, it would boot again and I had to pull the battery.
Does anybody know what vol up and power does?

I actually started a thread a looong time ago asking the same question. The answer was, and still is, no one really knows.
Though the thought is it has something to do with communicating with the processor, JTAGs, and unbricking your phone like they use to do in the G1 days.
too bad we don't know. Thanks anyway

Help plz. Inc brick?

Ok i ordered a relpacment Droid inc. I got it and before i decided to send in my old inc i went to unroot it. But after the phone shut off after running the first step of the unroot process my phone didnt reboot it just stayed on a black screen. i held the power button to try to turn it back on and all it did was vibrate. The phone still charges when plugged in so i know its not a TOTAL brick. But is there anything i can do to fix this. Also im running the new radio version but i have unrooted before with this radio.
Have you tried a battery pull? Sounds like you may have done power + vol up instead of vol down.

Yeah i did a battery pull. And when i do volume and down it vibrated but the screen stays black. I know its not my battery cause I can put my battery in my new inc and it starts up just fine. the process I used to unrest as I stated I've done many times. so I don't know what could've gone wrong.

Help wanted, is my HOX hard bricked?

Hello all,
I have a tegra hox with cm10.2 installed. this morning i updated cm10.2 to last nightly version. I forgot to flash boot.img so it crashed somewhere during the update process at the first boot. Rebooted the phone to flash boot.img via fastboot, but I selected recovery instead of fastboot. Powered off my phone again to go back in hboot to select fastboot. Surprise, my hox wont boot at all. holding power button or vol - + power button wont turn on my phone.
-My hox was 100% charged
-no noticifation led when plugged via usb cable (tried 2 different cable, 1 is the official htc cable)
-no notification led when plugged via wall charger
-menu buttons blue led wont flash with vol- + power button
-screen is always off, cant boot in hboot mode
-when connected to computer, no detection of hardware changes in devices manager.
I can't understand why my hox would be bricked because I rebooted it.
any suggestion?
I think my motherboard is dead.
I bought my hox last year at launch, s/n:HT23XW....
motherboard p/n is 50H00755-18M and I can't find a replacement board on the internet. Is there others motherboard p/n compatible for the endeavoru? (like p/n 50h00755-47m) I'm considering replacing it by myself and i dont want to send it to HTC for repair, I don't want to deal with their poor service again. Anyone on xda selling their broken HOX for parts?
HTC customer service sucks my one v was acting up so I warrantied it and got one back that runs worse than ny first one.

Sure you have a Tegra HTC One X? Cause mine does not have a blue led!
Maybe you have a hardware failure, have you tried pressing and holding only your power button for more than 5 seconds?

Yes, Tegra 3 HTC One X Endeavoru. Sorry for the confusion about blue led, im talking about home, recent app and back buttons that are blinking blue when holding power and volume down just before booting in hboot.

So im looking for a motherboard but im a little confused about wich one i need. I have the early motherboard p/n, the one with wifi issue. I think i must search the new motherboard p/n, after htc fixed wifi?

My HTC 10 just died today :(

So my 10 just died today.. what happened was... it still has around 41% battery but I decided to change is already since I will be going out. after 30 minutes I checked the phone but it was turned off and not charging, led is turned off. I am using a Choetech quick charge 3.0 charger with original HTC type-C cable. I already tried some possible fix around the internet but none of them work. So I assumed this is a hardware issue caused by maybe an incompatible charger. Although I use this Choetech charger for over a month already without any issue whatsoever.
My question is.. Which part/s would be possibly damaged of using an incompatible charger? (battery, charging board?). HTC devices are no longer released in my country anymore so no HTC repair services are available. Sending it to country where I bought it for repair might take months so last option I'm thinking is to repair and replace defective parts myself.
Hope someone with HTC hardware expertise will help me...
Maybe you could only ask HTC about this issue, they could have an idea. But, for sure, you won't be able to make it repair with warranty as you used a non-htc charger.
Unfortunatelly, I really don't know about it.
As you had still 41% of charge, there is power in so rather sure the battery is down but what about the rest?? I hope someone can help you more
So it doesn't power on at all, even with holding the power button for 20 secs?
Download mode also?
I would definitely contact htc about getting it replace/repaired...a bit expensive of a device to not use its warranty...which has to be honored.
You used a QC3.0 compatible charger...that is the requirement; OEM is not the requirement.
Unless someone can prove a defective charger is the cause (it's not like OEM equipment can't be defective or break), it would be an assumption made in bad faith.

Thanks for your replies...
I will try to contact HTC Taiwan. Sure they can help but I am concern on how long the process would take to ship my device to them for repair and send it back to me.
just for info.. this is the charger I used > Choetech
And this cable I used in the office to connect my device to my computer > Choetech cable

Incorrect. There is no way for HTC to know what type of charger was used.

Yeah, I think that HTC should be a nice option. even if you don't send the phone back to them, they could give helpfull informations. And maybe, ask other users that live in your region if they already had to send a phone back to htc and see with them if the delay is acceptable. As HTC will be thet best for it for you to keep your warranty safe

Their service is actually very fast. The offer an option where they will send you a replacement phone right away and put a hold on your credit card and remove it once the device is in their hands. If you do not choose that option and send the phone in and wait for repairs (which i have done before) it took less than a week.

While unplugged did you hold volume up and power for 30 seconds?

With the 10, try power + vol up + vol down. A bit different than on previous models. The capacitive keys will blink several times, then the phone will reboot. If you need to get to download mode (or bootloader which you can access from download mode), switch to power + vol down immediately after the phone shuts down to reboot.
I had to use this method myself twice today while testing a beta ROM and getting a black screen after the flash.

The capacitive buttons don't blink holding down all buttons (vol up and down plus power)? Crappy. It sounds like you've got a hard brick. After my response, I got black screen four more times and was able to get back running. Six times in total. If they are blinking, keep holding them down 'til reboot

No response at all. It's a hardware issue I think.
Already contacted HTC SEA (Singapore.) They just redirect me to their HTC TW counterpart as my device came from Taiwan. Unfortunately, after days of trying to chat, no response from them until now . Really disappointing!

No! The volume buttons are a rocker and if you hold both of them, you may break the button. There was a case review video that showed this happening (no idea which one; I've watched many).
You only need to press power + one of the volume keys (I don't remember which one, down I think...for download mode) to get the effect you described.
It worked when my phone was comatose from the PC BSODding during an RUU.

Incorrect, but I was too.
Vol up + down + power forces a reboot. I was responding after beers, and didn't realize/notice that he was trying to boot up from a powered down device. That's why I said as soon as it powers off to switch to power + vol down.
It won't break the buttons. It's the way that HTC has made the 10 to force reboot. I don't think they would do that if it would break the volume rocker.
Power + vol down from a powered off state should boot to download mode in the situation he is having.

Tell htc to update their documentation then:

HTC 10 not responding?
If HTC 10 does not respond when you touch the screen or press the buttons, you can still restart it.
Press and hold the POWER and VOLUME DOWN buttons for at least 12 seconds. HTC 10 then restarts.

And it works. Thanks for that.
When I tried this a few weeks ago when having issues, my phone didn't respond to it. I had to ask in the Venom Beta Hangouts chat what was up. I was told press both vol up and vol down + power, and that did work for me so I stuck with it. Maybe it was a problem with the situation I was in at the time.
Thanks for all your suggestions.. but none of them work.. the device does not respond..

HTC One M8 Totally Dead (No Access to Boot Menu)

Hello everyone,
Thanks for always helping in times of trouble.
I was using my HTC one m8 normally, playing with facebook. The battery was on 82%. Suddenly the screen frooze then the whole phone went dead completely. Not even a screen backlight. I tried to power it up. It didn't work. It had original ROM, with no modifications whatsoever.
Here is what I did so far, without any results.
- Charge it for few days with original charger and cable directly from the wall. No sign of life. No charging flashing light.
- Charge it with another cable. Nothing.
- Tried to access the boot menu to wipe everything clean. Pressed power+volume down. Nothing. Dead Screen.
- Pressed power +volume up. Nothing. Dead Screen.
Pressed power + both volume buttons. Nothing. Dead Screen.
- Connect it to the computer with updated HTC Suite. The computer said no phone connected.
I using a crappy old iphone now, but would love to get this HTC back to life. Any past experience with similar situation?
Any tips to resuscitate the dead phone?
Thanks a lot for your help.
In some "stuck" or powered off conditions, you may need to hold the button combos for a minute or so, before it actually reboots. So make sure you are holding them long enough.
But the fact there isn't even a charge LED, is concerning. Even in brick conditions, you should get at least an orange/red LED (maybe blinking? Can't remember). Makes me think the battery is bad.
Also play around with the button combos with the charger connected. I've seen a couple folks have luck with this, when nothing else seemed to work.
Additionally, the phone won't connect to PC when powered down; even on a working phone. You at least need to get to a bootloader screen to connect to a PC in any way.

I tried to do as instructed but it didn't work. I held the buttons on different combinations for at least two minutes but the phone stayed dead.
The only changed I noticed is one point I saw a very weak charging flash then it quickly disappeared and never came up again even when I repeated the process. Does this say anything?

Hard to know if this means anything specific. The symptoms don't look good. Might be bad battery, or other hardware failure.
