[Q] Phone Stuck Operator Logo (no USB debugging)

Hi,
My HTC Desire HD is currently stuck at the operator logo screen. I've tried removing rebooting battery going into boot-loader, resetting factory settings but still no luck.
Also as there is no way for me to boot into the phone to turn on USB debugging to re flash what can I do.
I've tried fastboot via boot loader it doesn't recongise the device on the pc (as I believe USB debugging not enabled)
please help

How did you end up like this? adb works only with a fully booted rom and not in hboot. Factory reset deletes the usb debugging drivers, so you wont be able to use it now. You can use fastboot command to flash in fastboot usb.
Are you able to boot in hboot? and are you S-OFF? then try flashing a ruu from fastboot. Use the guide in my signature to help yourself...if you need further help, just let me know.

Yes can boot into Hboot, Yes I have unlocked my device via HTCdev.
I have tried installing custom roms but they all fail and I believe this is due to me not having root.
I have also tried the t-mobile stock RUU that has failed aswell from fastboot

Have you flashed the boot.img in fastboot? That is the way to flash a custom rom with an unlock bootloader....check the guide in my signature to help yourself. If you need further help, just let me know.

[Q] Stuck on HTC logo after flashing custom rom

I have an HTC Desire HD.
I unlocked it
s-off
rooted
flashed with cwm recovery
installed from ZIP file on SDCARD
rebooted
stuck on HTC logo regardless of what I attempt.
I have no idea where to go from here.
Any ideas?
Thanks

did you made full wipe?

What ROM?....which version of cwm? These are important factors

ClockworkMod Recovery v 5.8.1.5
I have tried different ROMs, all end up with the same scenario
cm-10.1-20130301-unofficial -ace
cm-JellyTime_R17.zip
I hope this answer helps you help me

Can you access boot loader? If so , go to it and post results of "fastboot getvar all". Maybe running an ruu will get u back on track.

Yest, bootloader is accessible and I attempted an RUU and ended up with the same result.
I will post the results of getvar all when I get home, stuck in traffic now
Thanks

Is this were it stops?
No one has any idea to what it could be, no need for an absolute solution, a mere possible or a reflection as to what I could have done wrong would be appreciated.

LOL
What can i say to you?
As you stated on very first post of yours where you mentioned that your device is S-OFF? then why "INFOsecurity: on" ??
Simply flash any custom rom then extract boot.img from that custom rom .zip file and flash it through fastboot using command "fastboot flash boot boot.img"
Afterwards it should boot normally. Recovery has no issue nor given rom as you've mentioned on your post. Just requires boot.img to be flashed as your device is S-ON! not S-OFF.

I read a little sarcasm in that LOL
Thanks for the valuable info, I will attempt that as soon as I get home.
I will give feedback as to how successful my attempt has been.

I have attempted the proposed solution and I got the following error:
failed (remote: signature verify fail)
I read that could have to do with the fact that my bootloader is locked again. I did run a while back fastbood oem lock.
oem unlock returns an error.
So I attempted with the htcdev unlock code.bin again and unlocked it.
I ran the boot.img as instructed again and this time it was a success although it gave me a scare with the 4 reboots it performed
Thanks for the help, the tip from dr.patron99 was very helpful.

S-OFF Problem

Hi all.
i apologise if something similar has been posted, I can see nothing that matches my situation thus far.
I used to have a DHD which was S-OFF, sim unlocked, rooted and so on which I passed on to a relative when I upgraded, and went with samsung suff for a while.
Now I'm back on a Desire HD I bought from eBay, which works fine, its unlocked, and so on.
But I want to go to an older revision of android, or a custom one for performance reasons, because as it stands, the stock rom on it is useless.
I have CWM Touch recovery installed, and I have an unlocked bootloader, but no matter what I try I cannot S-OFF the phone.
I have tried installing custom roms which go nowhere, because from what I can gather, S-ON wont let it boot.
The phone was originally locked to Orange, and is branded with thier logo etc.
Android 2.3.5
Sense 3.0
Software Number 2.13.61.5
HBOOT-2.00.0029
RADIO-26.14.04.28_M
Is it possibe to S-OFF this phone or am I stuck with it this way?
I've tried ACE Hack Tools, but it didnt really get very far. I tells me to download PD98IMG-GB2 which I did (once I managed to find it) and tried to flash it, which also went nowhere. Nothing works, that I know of at the minute anyway.
Anyone know anything else to try or what I'm missing?
Thanks.

U need to connect device to PC and issue a cmd prompt "adb reboot bootloader". Then in bootloader ,type fastboot getvar all..and post its results
WE need these details so we can properly assist you.

If you want to S-OFF your device you should read this guide very carefully.
In the first step it's telling you to take a backup your kernel (boot.img) using dd command from root shell if you want to make the current rom working again after the s-off process.You could also make a nandroid backup from your recovery instead.
Then you have to make a goldcard in order to flash an RUU without a signature verification.If you want to downgrade your firmware you should downgrade your misc version to a lower value from the version of the RUU you are going to use to downgrade.You have also to flash an unsecured kernel (for example the boot.img that's included in ace-tools folder) and the revolutionary recovery (included in ace tools) in order to make the process correctly.
After that you can flash the firmware.zip cooperative with the radio exploit to be able to s-off your device with g-free.(In order to be able to flash the zip you have to relock your bootloader)
After this process has been made correctly you should be able to see S-OFF in your bootloader and you can restore kernel and recovery or a nandroid backup to make your device working again.You can also use an RUU.But definitly you have to upgrade your firmware after the process.

At first you have not to make a boot.img.
Secondly with dd command you can copy a hole disk or partitions either sectors in raw mode.The only think that the S-OFF guide describes you do with it is to backup your original kernel by backing up your hole boot partition in order to make you rom working again (after the S-OFF proccess).
The guide for S-OFF I gave you describes exactly how to make a goldcard using a root shell.You have not to do something special but to follow this guide.
A little more specificly:
Code:
adb shell cat /sys/class/mmc_host/mmc2/mmc2:*/cid
This command gives you the goldcard number of your phone.
Code:
adb shell /data/local/tmp/goldcard -c {sd card cid above} -o /data/local /tmp/goldcard.img
This command creates a goldcard token with your goldcard number.
Code:
adb shell dd if=/data/local/tmp/goldcard.img of=/dev/block/mmcblk1
And this command writes the goldcard.img (token) we created on your sdcard in raw mode.(By making your sdcard gold you could flash anything.It could also break your device if you don't know what are you flashing)

means I should stay away, as I AM novice user. If any thing goes wrong i will be in deep trouble.

I just explaned you what you are going to do with those proccesses like you asked me.If you don't understand or you don't feel free to make the proccess you shouldn't try it at all.As long as you follow the right instractions and you apply them correctly you have nothing to be afraid.(You have to remember that any time something could go wrong even if it is not your fault like some power failure).
But personally I think the only risky part is to make the proccess of radio downgrade right.After that it should be a piece of cake to make the S-OFF trick.

Aahk 2. Here on xda

Yes, the AAHK2 does not work for me, hence starting this thread. However, I solved my issue. The trick to it is not S-OFF at all, it merely requires an unlocked bootloader. Is probably slightly more hassle than S-OFF, but I don't care, it works. All you need to do is extract the "boot.img" from the ROM you want. Place it in your ADB folder.
Install the ROM via recovery and then reboot to the bootloader (you can do this via adb but for my sakes I removed the battery and used vol- & power to boot into it.
Then you flash the boot.img using "fastboot flash boot boot.img" and then "fastboot reboot" and it should work fine, I managed to load up cyanogen mod not a problem this way. Whereas before, installing a rom would not work whatsoever.

You don't need to S-OFF if all you want to do is flash a custom ROM. You do need an unlocked bootloader, and a recovery installed.
Assuming both of those are the case, do the following: On your computer, download the custom rom you want and and open it (it should be a .zip file) in any file archive utility and find its "boot.img" and extract it. If you can't find it manually, search for it, winrar allows you to do this. Place it in the same folder as your adb and fastboot tools for instance mine is C:\adb
Copy the custom ROM.zip file to your phones SD card, and install it normally via the recovery. Once this is done, reboot the device into the bootloader. I do this by just taking the battery out quickly and putting it back in, and then holding Vol Down & Power. when the boot loader shows, highlight the "fastboot" option and press the power button, then connect it to your computer via usb. Then on your computer, (i assume windows), press the windows flag key and the R at the same time, this brings up the Run prompt. Type CMD in it to open the command promt. then navigate to yoru adb folder using the "CD" command, for example:
CD C:\adb
once you have done that, type the following:
fastboot flash boot boot.img
(remember I said to place the boot.img in the same folder as your fastboot/adb tools)
It should push the boot.img that you extracted earlier to the phone, its usually very quick. Once you've done this, type:
fastboot reboot
and then unplug your usb cable. The phone will take a while to start up, but it will work, regardless of S-ON or S-OFF. My phone is S-ON and I can flash ROM's using this method.

Thanks for This Great Help
I decided to give it a try, did all as you said but when I went to recovery mode there is nothing but Red Triangle and Disk Image.
Now what to do?

it sounds like you need to flash a recovery first of all. I have attached a recovery image you can use, its is TWRP; you need to flash this via the bootloader. copy the recovery.img to the same place as your adb folder, take the battery out of your phone and put it back in and hold Vol Down & Power, and then highlight the fastboot option and connect it to your computer. Then using CMD (Windows flag & R) go to your adb folder (cd:\adb) and type:
fastboot flash recovery recovery.img
when this completes sucessfully, type "fastboot reboot recovery", which should take you straight there, then continue with the previous post instructions.

Update Android to 6.0 error

Hello. My problem is on picture. Please help.
http: // s23.postimg. org/5sizlitkb/DSC_0015.jpg
Please remove space.

Is the OTA file on the phone? Downloaded after getting the update notification?

I got an update and started downloading.
The system asked whether to install the update and clicked yes. And after 30 minutes, there was this error

I have exactly the issue too following OTA stock update
When speaking to HTC Support, they said that my IMEI showed up as a US device, even though the last ROM was definitely European stock. When going into Bootloader the following information is shown:
***Software Status Official***
***Locked***
M8_UL PVT SHIP S-OFF
CID-11111111
HBOOT-3.19.0.0000
RADIO-1.29.214500021.12G
OPENDSP-v51.2.2-00593-M8974_FO.1015
OS-6.12.401.4
HTC UK advised that they cannot help and pointed me in the direction of HTC US, but I cannot get through on their support chat pages, so currently have my phone stuck in this state. My phone is the 32GB version and upon further investigation I see that this was only released in the US.
I have tried to do a RUU update via http: // www .htc.com/us/support/rom-downloads .html#additional with the Unlocked/Developer version, but the RUU will not see the phone when in Recovery Mode, so fails to get along any further.
Any further assistance would be great so I can get my phone back!
Just to clarify, the European OTA stock update was downloaded, and then installed. The phone rebooted and started the install and completed the install. It then rebooted I assume to start up in Marshmallow, and this is when the error occurred and the Recovery screen was displayed. So the issue I suspect is a European ROM on a US device.
Thanks in advance

Go into bootloader-fastboot mode, and do fasboot getvar all, and post the output. Delete IMEI and serial number before posting.
I need this info to see what version the phone originally was, and for that matter what RUU will work.
If you have WWE (Euro) compatible CID and MID, you might try RUU linked here: http://forum.xda-developers.com/showpost.php?p=64869806&postcount=4
I can't personally vouch for this RUU, but I think several folks here have posted the link, and its probably legit.
Also, you need to run RUU in bootloader-fastboot mode, it will never work in recovery.

Thank you for your prompt response - I'm not sure however to enter any commands in FASTBOOT, as when I select REBOOT FASTBOOT from the options, it just reboots the phone and I go back to the bootloader screen with FASTBOOT highlighted under the date and above the Vol Up Vol down insutructions. From your comments I suspect you are expecting the phone to go into another type of functionality

Nope, if FASTBOOT is highlighted in red, its in fastboot mode, and no need to do anything else. Just connect the phone by USB (if not already) and do the fastboot command.
The only other bootloader mode would be HBOOT, which is not what we want.

Sorry to be a pain, but as I have not flashed a ROM since the good old HD2 days, I'm a bit rusty and probably do not have all the tools on my laptop to do this. I only have HTC Sync Manager installed. Launching a command window in Windows and type: "fasboot getvar all" I get "fastboot is not recognised as an internal or external command". What additional tools do I need to install, as quickly looking around there seems to be a plethora of different thing for different setups

HTC Sync should be enough.
Do a search on Windows for fastboot.exe, once you find the folder where that is located, you will need to change directory in your command prompt to that same folder.

Nothing found I'm afraid - downloaded "fastboot-win.zip" from https://www.htcdev.com/images/uploads/fastboot-win.zip?legal_license_terms=1, but when called from a command window I get "This program can't start because AdbWinApi.dll is missing from your computer", so looks like I only have one part of the jigsaw

You can find a couple good and simple installers if you use the XDA search function and search "easy adb".
Although, if you get Error 12 when running the RUU later, you may need to uninstall this.

I have found an ADB installer at http://forum.xda-developers.com/showthread.php?t=2588979 so have installed this and run the command to get all variable, but command window is just sitting at <waiting for device>. I have rebooted phone again back into bootloader, just to see if this would kick start the connection, but nothing. I have unplugged and plugged the USB cable again to try and get it to be seen, so scratching my head at the moment!

The phone is just not being seen by the laptop at all and does not appear in the Device Manager of Windows. I have tried it in different USB ports, but no difference....

Try to uninstall HTC Sync, and re-install.

Perfect - thank you shade550. That RUU worked a treat.
Thank you redpoint73, your patients and guidance was a god send and I could have not achieved any of this without you

Damn, I should have figured it was something simple like the cable. Its seems the simple, seemingly obvious stuff is most often the answer. So much so, I forgot to even consider it.
Glad you sorted it out. My pleasure helping, really.

Hi redpoint73, I'm still stuck with this problem. I don't understand how to install de RRU that you had post in the first page. My phone is manufactured in the UK.
I already installed the HTC Sync Manager, and the adb.
What's the next step for installing this? Sorry but I'm no quite good with this stuff.

1) Connect phone to PC.
2) Boot phone to bootloader-fastboot mode
3) Run the RUU.exe, and it will walk you through the rest

HTC M8 Stuck in Recovery Mode!!! Please help a noob

Hi there, A friend at work has given me his M8 which appears to be stuck in recovery mde t see if i can get it back to working or can do anything with it.
I have samsung phones myself and while i know how to flash a stck rom etc to these, reading on some of the threads here it seems alot more complicated process on the HTC....
I have not had any experiencewith HTC devices since the HD2 days (what a great phone) so really need someone to walk me through what software/firmware i need and where to find it and what to do with it?
At the moment, it turns on, then goes into the recovery menu, then I choose wipe data/cache, and restore factory etc, but it then just comes up with done, choose the reboot option to come back to the recovery mode again........
I think it is a stock uk/eu release of the M8, don't know what network it was on or whether it was rooted/unlocked before hand.
Any help would be greatly appreciated!!!

In the recovery menu I believe there is reboot to bootloader option. Select that, then tell us what's written on the bootloader
Search on how to do fastboot getvar all then post the result without serial & imei no.
Then we'll see anything we can offer to help
