HTC desire in boot loop. PLEASE PLEASE HELP! - Desire 820 Q&A, Help & Troubleshooting

My HTC desire 820 keeps restarting itself as it is stuck in an endless boot loop. I have come across threads speaking of the same issue but the solutions don't seem to work on my phone.
My boot loader is locked. When i try to unlock it in fastboot mode, the device doesn't show up on the PC.
I need the boot loader unlocked so that i could push in a custom recovery mode as i cant get into the stock recovery too.
Does anybody have a solution for my kind of problem?
Also, when the phone is in fastboot usb mode, the computer makes a notification sound which indicates it recognizes the phone.
The only thing i can get into is my boot loader and which looks like this now:
***LOCKED***
A51_DTUL PVT SHIP S-ON
HBOOT-3.19.0.0000
OS-3.17.708.3
eMMC-boot 2048 mb
Apr 12 2016, 11:49:54.0
NOTE: I never tried to install a custom ROM. This problem arose on its own for reasons unknown to me. Moreover, my phone is UNROOTED.
PLEASE SOMEBODY HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! PLEASE!
I'm clueless!

Have you installed the adb/fastboot drivers on your PC?
Sounds like a drivers issue to me.
Try this thread to install the drivers then try communicating with the bootloader again.

Thank you for replying, friend.
I did what you asked me to do i.e. installed adb/fastboot drivers and then ran the command to identify.
But all i get is this. I have attached a screenshot of the message i'm getting in the command prompt.
What do i do?

Still a drivers issue
Try installing HTC Sync Manager from here and try again.

I had installed the htc manager again as per your instructions even though i had it on my pc earlier.
HTC sync manager doesn't detect the phone.
Nor does fastboot command in the command prompt.
i have the adb drivers installed as you asked me to install them earlier.
I get the same message "waiting for phone" in cmd. I rebooted fastboot but even that doesn't change anything.
What do i do now? Is it a hardware issue? I do not think it could be a hardware issue because the phone has never undergone physical damage. it just decided to turn itself off one unfortunate day by itself.
Is there another way? another software?

Open device manager.
Connect phone to PC. Does the device manager show a new device added?
And BTW why can't you get into the stock recovery?

When i select "fastboot mode" in the bootloader screen, the PC makes a connection notification sound.
And the device shows up as "Android 1.0" in Device manager.
I have attached a screenshot which shows the same.
Also, when i try any of the options in the bootloader i.e., factory reset, recovery mode, reboot or power down, the device goes back to the endless bootloop and never really lets me do anything.

[Q] How to recover RECOVERY?

Hi guys!
Today I tried to get the rooted desire with Android 2.2 with unrevoked 3.21
Previosly I updated to 2.29.405.2 SW
When I run the unrevoked it (desire) freezed on "waiting for root" step. Desire freezed in boot progress (white screen with HTC logo on it)
I removed battery and inserted it again. But I cant boot it, desire freezes on the same white screen with HTC logo.
I can HBOOT, but when I go to recovery menu my device goes to reboot and freez.
So it seems that unrevoked spoiled my recovery and I do not know hot to fix it.
Please guide me, the working solution will be donated $20
--------------
Radio version: 5.11.05.27.
SPL/hboot version: 0.93.0001.
product: bravo.
mid: pb9920000.
security: on.
build-mode: ship.
Device model is not SAPPHIRE - flash old/new disabled.
This device does not have s-off nor eng hboot.
-------------
Thanks!
Flash a stock RUU and try again, you can get 2.29.405.2 from my signature. Remember to use a gold card if you had to in the past
How can I flash the RUU without access to recovery?
You should flash it via fastboot.
Hold the back button and turn on your phone to enter FASTBOOT, then connect your phone to the pc with the usb cable and then run the ruu.

Did it as you said, result is the same
After the successful flash procedure thru RUU device went to reboot and freezed at the same white screen state.
Recovery is still unavailable to get into.
Now I will try to get the logged data thru Android SDK.
This thing is really mess me up =( I'm phoneless.
You, guys, are the one and only hope.
I have installed SDK, but I cant see anything in adb logcat but "waiting for device", thogh my device is conneted via fastboot usb.
Any clue?
I had that same issue, and it turns out it was a problem with the earlier version of clockworkmod (2.5.0.1) that had that issue, where freezing occurred at the HTC splash screen.
Try unrevoked again, with the 2.5.0.7 image here:
http://koush.tandtgaming.com/recoveries/recovery-clockwork-2.5.0.7-bravo.img
Make sure you select the image when you start unrevoked.
It might fail a few times (freezing at splash), but if it does, just pull the battery and keep trying....eventually it'll manage to go through.
Good luck =)

Latty, how can I run unrevoked with a desired image if I cant boot the phone to get it recognized by unrevoked?
you have to start the flasher without the phone being connected, then you should be able to select the image (top left of window).

It still is a driver issue.
Start from scratch..
Remove all HTC Drivers
Reboot
DC from internet
Connect phone in two modes-Android, Fastboot
It should get recognized but drivers shouldnt be installed and you should be prompted for driver location. If you arent prompted, get Device Manager, uninstall the driver which recognized the device.
Now install Unrevoked drivers as per guide.
Phone should be recognized..

Ok, thanks will do it now.
But one more question, should it be recognized from hboot usb mode with "Android Bootloader interface" driver, or from fastboot mode?
Cant confirm that without my phone..
But, I believe drivers would recognize it in both..And seperate drivers too..
A small tip..If you have dual boot, try Unrevoked in another OS in which you havent installed HTC. Should work

Faced with problems
1) I uninstalled HTC Drivers.
2) plugged phone and deleted Bootloader interface device then Boot Interface device.
3) rebooted
4) disconnected from internet
5) plugged and powered device and got Bootloader Interface driver installed without a single promt!!! And Boot interface as well.
So I had no chance to manually set the path to the drivers. And unrevoked still doesnt see the device =(
It turns out that I should try another OS???
PS and the key point, should it be recognized in hboot mode or unrevoked only works with booted to OS devices only?
Not really..But that's the easy way out..
Difficult to show you what exactly to delete..
Mostly these are driver clashes..When you uninstall the driver you should tick the option to delete the driver from system.
Try again and you know you've succeeded when it doesnt find any driver installed, and asks you for the location, when you can choose the unrevoked drivers..
Hm, I cant find any options prompting to delete driver from the system... But I will look into more carefully.
ADDED
Found it, trying now.
Tried, was promted to specify the path to the drivers, installed again and with no luck =( Unrevoked doesnt see the device.
I will try it tomorrow on another PC and with another OS.
Thanks for help, I really appreciate this, and I hope we will find a solution.
PS. Is this problem called USB brick?

fastboot mode not working

hi everyone, i'm trying to install CM9 on my LT15i, i've tried using the CM wiki instructions and both the following guides...
androidauthority.com/xperia-arc-lt15i-root-android-4-0-ics-80265/
and
androidforums.com/rezound-all-things-root/506466-scottys-noob-friendly-root-guide-start-finish.html
the phone is already fully unlocked and has CM 7.2.0 anzu installed. i've tried simply using the clockwork recovery mod bootloader to wipe the phone and install CM 9.0.0, but on reboot the phone gets past the boot logo then just shows a black screen, so i assumed i needed to flash an appropriate ROM for CM9; this is where my problem begins.
every forum i've read about this process says i must enable usb debugging (done) and "disable fastboot" under settings>power, i do not have a "power" option in my settings and cannot find anything related to fastboot on the phone; although i'm not sure this is the problem. when android is running normally and i attempt to list devices with adb.exe on windows, it successfully returns the phone's serial number. when i shut the phone down, hold the menu button and plug in the usb cable, fastboot mode appears to work correctly as the LED comes on blue and "android adb device" appears in the windows device manager (i've tried installing the arc usb/adb drivers from various sources, they all seem to work correctly). but when i attempt to list devices after restarting in fastboot mode, adb.exe says it cannot find any device. fastboot.exe has not communicated with the device whatsoever, but i assumed i might need to get the adb.exe usb daemon/server running correctly first for this to work.
i did this process once already when i installed CM7, it was successful the first time and everything went smoothly. from what i recall i just did exactly as described above and fastboot.exe was able to find the device no problem. but that was a number of months ago, hopefully i'm just missing some obvious step.
cheers

There is no such thing. And USB debugging is only required if you want to root stock ROM, every other action can be done without it.

Drivers, drivers, drivers.
If your phone is in fastboot mode, make sure drivers are installed. Proper drivers.
You do not need ADB server for installing a kernel.
Just open up Command Prompt and install the kernel with command
Code:
fastboot flash boot boot.img
.
Assuming boot.img is in the same folder as fastboot.exe.

thanks for the reply someguyfromhell. i've tried every "android adb interface" driver under the sun for the S1 fast boot device that appears in the windows device manager when i put the phone in fastboot. when i try to send any command with fastboot.exe it just hangs at "waiting for device", i've fiddled with this stuff every which way and just cannot get fastboot.exe to see the phone. i've tried switching up the usb ports on this computer, but haven't had the opportunity to try a second computer. you've let me know i'm going in the right direction at least, if i have the same results on a second machine i'll pursue the issue further.
thanks again

You need to unlock bootloader, if you want to install CM ROM. Arc S can only have bootloader unlocked via official method, there you can also download the correct driver which you need.

GPS lock and Lollipop problems

Hello wonderful helpful android wizards out there! I humbly seek your help.
I recently purchased an unlocked HTC M8 AT&T and had it unlocked so I could use my prepaid carrier (Simple Mobile). I have two issues I would like help with:
1) I cannot get a gps lock at all. I have made sure the device is in high accuracy mode and I have tried downloading and refreshing aGPS data via the GPS status app.
2) I am trying to upgrade to lollipop using the provided RUU file on the HTC website:
http://www.htc.com/us/support/htc-one-m8/news/
I am currently running 4.4.2. I was hoping that upgrading to the latest firmware might solve my GPS problem as a bonus, though I obviously want lollipop anyway to just generally be up to date. HTC sync manager works fine, but when I run the RUU file, it says the phone is not connected. I have tried the PB99IMH solution posted here that seemed to work for many people:
http://forum.xda-developers.com/show....php?t=1928439
The roadblock I have hit is that I cannot copy the zip file onto my Android. I keep getting the error "The device has either stopped responding or has been disconnected." I can copy other file to the phone just fine. I tried fiddling with the permissions of the file, but I honestly don't really know what I'm doing with those.
So those are my problems. I would greatly appreciate any assistance.
While in fastboot/hboot mode. Is your device recognized?
Where you have adb installed just open up a command prompt and do "fastboot devices" ... If your device's serial number shows up then it's being recognized. If not then your drivers are not installed or not recognized.

Thank you for your response.
I never explicitly installed adb. I have sync manager on my computer, and I can see adb.exe in my processes. I tried to open up the command prompt and typed "fastboot devices" while my phone is in fastboot usb mode and nothing showed up. When I tried to run the RUU file while the phone was in fastboot, i never got beyond the "verifying information on your android phone. please wait..." part.
EDIT: I would also like to point out that sync manager doesn't recognize my phone in hboot or fastboot, thought it does recognize it normally.

It not being recognized while in the bootloader via the HTC Sync app is normal.
You could flash an RUU from the phone itself. Simply copy the rom.zip to your sdcard and go into the bootloader it'll see it and flash aslong as its named properly.. ie 0PB6IMG.zip or something in those lines.
To get the rom.zip while the RUU is open go into your task manager and right click the ruu process and go to file location. The only zip in there thats ~2Gbs is the rom.

Ok, i finally got the update to work, but I am still having GPS issues. Any ideas?
I am also having GPS issues. Everything else on the device works fine, it just never finds any satellites. Any help or updates would be nice.
I'm having GPS problems as well. I'm on CM12.1. It used to work fine, but I've been playing with it trying to get LTE to work, and somewhere in there, my GPS stopped locking.

Stuck in bootloop and PC won't recognize drivers

Hi,
I recently changed my broken screen and now my phone is stuck in a bootloop. I want to try and flash ROMs but cant because the PC does not recognize the device. I've tried manual installation of drivers in device manager but it said that it cannot find the driver, even though i chose the HTC drivers folder in HTC Sync. So yeah i've tried putting 0P6G(whatever) on the SD card and it doesn't want to install it.
Device details:
Software statusfficial
Locked
m8_ul pvt ship s-on
hboot-3.19.0.0000
radio-1.29.214500021.12g
openDSP-v51.2.2-00593-M8974_FO.1015
OS-6.12.401.4
i downloaded the HTC RUU.exe file and copied and renamed the zip file to 0P6G... and tried HBOOT and it didn't work. i've tried looking for the European version with the same radio number but i cant find a working link. Now i want to try flashing but cant, because my PC doesn't recognize the device. And also i tried factory reset and wiping and all that **** it didn't work. I didn't have any CWM or TWRP installed and USB debugging was off.
I have a very basic picture of how this works i'm not a developer and this is why i need your help. I'ts kind of new territory for me.
I'm using Windows 7.
Please help and tell me if you need anymore info i think i gave you everything.(if i didn't, it probably shows the level of noob that i am)
Thank you for your replies!!
Zip name should be 0P6BIMG.zip if you have to use microsd method to install RUU.zip
Here you can get the correct RUU.zip -

So i tried the SD card method with the file you sent me, it updated in bootloader, but when the phone rebooted it got stuck on starting apps... I tried the same method but in recovery the phone wrote
E:footer is wrong
E:signature verification failed
Installation aborted.
Still no sign of the drivers working. Windows stills sees the phone as an unknown device.

Just having HTC Sync installed should have installed the drivers.
Is the phone in bootloader-fastboot mode, when connected to PC?
Does the phone show up in Device Manager? Even if just as an unknown Android phone, or something to that effect?

Yes it shows up in DM as an unknown device and yes i had HTC sync installed. I can access bootloader and fastboot but fastboot doesnt say fastboot-usb. I also clicked ram dump through USB and the computer reacted like a device was unplugged and plugged back in, but it still remains as an unknown device. Ive even tried installing the drivers manually but windows rejects the ones that are in the HTC sync install foldeer

I don't know if there is any different in it saying fastboot versus fastboot-usb or not. Try opening a command prompt (within same directory as fastboot.exe) and do fastboot devices, and see if your device ID is returned. If so, do fastboot getvar all, and post the result (delete IMEI and serial number before posting).
I've never used the ram dump option. Don't think it will do anything helpful in the current condition.

So
-Downloaded SDK tools,
- installed the tools,
- opened a cmd window in platform-tools,
- typed fastboot getvar.
- also fastboot devices.
nothing the getvar was stuck at waiting for device.
Device status in DM under unknown device:
Windows has stopped this device because it has reported problems. (Code 43)
(i dont know if this helps)

Try right clicking the device under Device Manager. Select the option to update drivers software, if available. Then pick the option to look for the driver (forget what it says exactly) then pick the option to select the driver manually. Pick the option "Android MTP device" or something to that effect. Then after the driver is installed, see if the fastboot commands work.

If you want helpful responses you have to be more specific. Assuming you have the fastboot files installed on your PC/laptop ... What LG G4 model? What software version? Bootloader Unlocked? etc.
Assuming you have installed on your PC/laptop LGMobileDriver_WHQL_Ver_4.2.0 available for download from the LG US site as the Windows driver can create issues, have you tried downloading and installing the "Official" TWRP app and installing that way?
Suggest if you are still having problems, you head over to: https://forum.xda-developers.com/g4/development/recovery-twrp-3-touch-recovery-t3442424

Assuming you have installed on your PC/laptop LGMobileDriver_WHQL_Ver_4.2.0 available for download from the LG US site as the Windows driver can create issues, have you tried downloading and installing the "Official" TWRP app and installing that way?
Suggest if you are still having problems, you head over to: https://forum.xda-developers.com/g4/development/recovery-twrp-3-touch-recovery-t3442424
Read the OP thoroughly and post any issues you're having there.

I have the right files, when I get into adb reboot into bootloader
it no longer recognizes the device. I cannot flash twrp
After reboot into bootloader, open your "windows device manager" and see if windows detects your device properly.

Don't allow Windows 10 to update your drivers - you can set that up in Windows. Google it for the how-to.

The device type changes depending on "how" its connected. Windows can "see" it as a ADB device, MODEM, etc...
With the phone connected, uninstall all device related on windows device manager, refresh the device manager for it to detect the phone as it should be (as you need it to be detected).
Sometimes its needed a manual device driver install. Happens some times to me, unfortunately I don't remember exactly how I do it because the issues (when it happens) are kind of random, so, I need to "understand" what is going wrong and fix it.
Just to tell you that is nothing unfixable on the procedure, you just need to have patience and find out how windows is supposed to detect your device.
If you don't find out by yourself, tomorrow (Monday), I'll try to see on mine how it should be detected in fastboot mode and tell you. Today its already late for me...
Good luck

everytime I boot into the bootloader the driver stops working.. when I boot the phone normally windows doesn't recognize my phone. it is unknown, so I remove the driver, reinstall it., get into bootloader and same issue persists "waiting on device:" I think the lg driver keeps crashing or it is windows issue
will try again tomorrow

Your device should be seen as "LGE Android Phone" (if your lg drivers are good).
Now gonna be tricky because my OS is in Portuguese, I don''t know exactly the path name in English... use your imagination
Connect the device on a USB 2 Port !!!
In windows device manager, select "update driver", "search software on the computer", "allow to choose from a list of avalable drivers". unmark the "compatible hardware" and find on the list the needed drivers. If the "LGE" drivers don't work, try to download Universal ADB Drivers, maybe it works.

I'm thinking it could be a corrupted LG driver. Download another from the LG US site, ONLY. Uninstall the one you have installed now, reboot and install the newly downloaded one. Then connect your phone and see if it is recognized and shown correctly in Windows Device Manager. Also, in adb type lsusb and see if the phone is listed in the output.

Boss, no need to struggle with this ADB anymore.. there is a tool called FWUL which was created for people who have driver issues... Check it out here:
