[HELP] Desire 820G+ Stuck on Boot Logo - Desire 820 Q&A, Help & Troubleshooting

Hey guys,
My friend has an HTC Desire 820G+ Dual Sim. It was running Android v 4.x (not sure what version exactly), was on a stock ROM, locked bootloader, and stock recovery, with USB Debugging disabled.
He was performing an OTA update to Lollipop, and after it downloaded (i.e. while installing), it gave an error message (he doesn't recall what it was exactly). It is now stuck at the HTC boot logo. (I think this is called soft brick?)
I can access the phone's recovery menu via Power + Volume Down.
Here's what I have tried to do to fix it:
1. Go to HTCdev and look for stock firmware to install on the phone, by means of copying the downloaded files onto the SD card (the recovery menu has an option to install files from SD card)
The problem with this is that I have found four different downloads for Lollipop, all having the same carrier (hTC Asia), version (5.0.2), region (TW), and kernel (3.10.61) but different "description" (e.g. 1.01.709.8) and "type" (CRC vs MR1).
I was desperate after I tried to look for alternative solutions, including the one outlined below, so I tried to install the .zip files (downloaded all of them), but not one of them would install.
2. Unlock the device's bootloader, install custom recovery, and flash a custom ROM.
The problems with this are:
a. The device has USB debugging disabled. I tried to look around for methods to enable it, and I will continue trying to do so tonight. Please let me know if you know how I can do this.
b. I could not find a TWRP image for the Desire 820. I tried to access the CWM website, but it is (for some unknown reason) blocked in my university, so I will try to look there again tonight.
c. I couldn't find a custom ROM for the Desire 820G+. I could find ones for the 820S and 820N -- can I install them?
d. The phone isn't detected anymore when I run adb devices or fastboot devices. I managed to get it to be detected as "sideload" once, but never again.​
To summarize:
1. Phone is HTC Desire 820 G+ Dual Sim.
2. Stock ROM, no root, locked bootloader, and disabled USB Debugging.
3. Phone is stuck on HTC boot logo, but I can access recovery mode.
4. Phone doesn't show in cmd when I run "adb devices" or "fastboot devices" (I know that drivers were installed properly because it worked once earlier).
Let me know what I should do.
Thanks in advance.

No don't ever flash Desire 820u, 820n or 820s files on 820G+, they are different hardware.
Was the device rooted before installing the OTA?

Here is the stock firmware for 820G+ which you can flash with SP Flash Tool:
http://easy-firmware.com/index.php?a=browse&b=category&id=2696
SP Flashtool link:
http://easy-firmware.com/index.php?a=browse&b=category&id=2697
How to flash (This will wipe internal storage)
1. Extract both files
2. Open SP Flashtool folder and run flash_tool as administrator
3. Click on scatter loading and navigate to HTC-Desire-820G-PLUS-dual-sim folder and choose MT6592_Android_scatter
4. Select all items except preloader

7. Wait for flashing to end, then disconnect USB cable and switch on phone

Have the same problem. I have tried to install the stock ROM with SP flash... But nothing happens. My phone is also desire 820g+ dual sim grey.
When I start the flash tool and choose the scatter than click download, switch the phone off to connect to PC via USB cable after this procedure nothing happens.
Waiting and waiting.
The USB cable is the original one.
What I'm doing wrong? Give answer as soon as possible.

You correctly install the driver on the Bootloader? Open Device Manager and plug the off-phone if there is an unknown device and disappears, so do not set the driver.

As he says. Follow the tutorial in this link to install the MediaTek USB drivers:
https://forum.hovatek.com/thread-440.html

I am more than sure that it is not properly installed driver for the bootloader, so Flash Tool can not pick him.
In the all critical condition phones on MTK flashing without any problems. The main thing that was a working memory and a connector.
Upload a photo where we can see that the drivers are installed on the bootloader. The device only a two - three seconds is displayed in the manager, then turns off.
Very often, the drivers are installed crooked, it is necessary to clean and re-deliver them. Very often, drivers are not suitable for the operating system or mobile phone, you have to try others.
Sorry for my English!

Correct MTK VCOM USB Driver Installation!
For those having problems flashing or upgrading with FlashTools, USB connection problems with this phone HTC desire 826G+ or any other Mediatek powered phone, sometimes you have to disable Windows driver signature enforcement (DSE) before installing MTK VCOM USB drivers. Check this post on my blog to properly install MTK drivers and get your phone recognized by the Flashtools program for successful flashing: http://www.selftechgenius.com/andro...-android-5-1-lollipop-latest-official-update/
Jump to the "Installation Process" part.
Hope this helps!:victory:

Can't flash hboot - Fastboot waiting for device - drivers up-to-date

I can't flash cm7r2 hboot neither through pb99img.zip, nor through fastboot.
flashing pb99img causes a short blink of some message (can't even read it), while fastboot is waiting for device indefinitely. drivers are up-to-date, Device Manager shows present Android Composite ADB Interface while plugged in.
I don't know if it is odd but connecting a phone via USB while in recovery shows unknown ADB device in dev mgr but can't update its drivers...
current hboot 0.93.0001, PVT-1 S-OFF
EDIT:
had a problem with recognizing the Android Phone when booted normally - i've manually edited the android_winusb.inf and changed pid value to this corresponding to my device's and have chosen Android ADB Interface as the device's name but still adb shell does not see any device ...
EDIT2:
solution in post#14 http://forum.xda-developers.com/showpost.php?p=16956020&postcount=14 . thanks guys!

have you installed the required drivers on computer?
I think so, but could you point those required, just to be sure?
Try this: http://unrevoked.com/rootwiki/doku.php/public/windows_hboot_driver_install
If that does not work (works for me on win7) - then try the official HTC drivers (by installing HTC Sync).
I've already used this driver. when the device is in fastboot mode, dev mgr recognizes it, installs drivers and everything seems fine, but when I reboot, it appears as Android Phone with no possibility to install the driver. strange :/
what is bothering me though is not the driver issue but impossibility to flash the PB99IMG through recovery. should I take some special steps to do so?? I put the PB99IMG-cm7r2.zip on sd, change the filename to PB99IMG.zip and try to flash it through recovery. I even tried PB99IMG-downgrade.zip but still no effect.

U have to put the PB99IMG.zip to the root of ur sdcard (not flash it in recovery), and reboot ur phone in the bootloader and wait it to ask u automatically to apply the update..then select yes with volume keys, and confirm the choice with the power button

If your phone is branded you won't be able to flash hboot via PB99IMG.
AFAIK a so-called goldcard might help, but not sure here so you may want to check this out on the forums.
As for the driver, I installed mine by the age-proven method of installing HTC Sync app on the PC and then uninstalling it.

U need the goldcard in the sdcard then
you are probably right, as I forgot that I bought a new one... can't I make a second GC ??
Sure. The goldcard is only sd card connected and it doesn't matter which system you are running.
SwiftKeyed from Oxygen with Transparent XDA App
I've made my SD a GoldCard and now get "CID Incorrect! Update failed." or sth like that. I guess I need to instert my original GC?
Guy I had this problem,too.
I downloaded the PB99IMG_cm7r2.zip renamd it to PB99IMG.zip,put it on Sd card but it doesn't work.
Then I opened rootExplorer and saw there that the filme name was PB99IMG.zip.zip (on pc only PB99IMG.zip) so I renamed it via rootExplorer bootet into fastboot & it worked.
Maybe you have the same problem.
installing and uninstalling HTC Sync + making my SD a Gold Card did the trick! both PB99IMG.zip and fastboot methods work.
soooo freakin happy, will try Lee 3.3.3 R5 with dalvik2nand now!

[Q] ADB won't detect my phone

Hi, I have a rooted Desire 816 currently running unofficial CM12. Before this, it will detect my phone, and thats how I root it and install custom recovery, but now, I tried to go back to stock but I couldn't get adb to work. It kept saying ADB error no device found.
Any help? I've already installed the HTC driver, same. Went to fastboot mode, on the phone it says fastboot USB but nothing happened.
In CM12 did you go into developer settings and enable adb?
yes i did. and it even showed up in the status bar. but still the same.

Then you don't have the proper drivers. You know adb and fastboot are different right? The rooting process doesn't involve adb, only fastboot. They're separate things and require separate programs to work.
Yes. But fastboot not working either. It's stuck at <waiting for device> and I can't lock the bootloader or flash the firmware.

Try to redownload fastboot, and uninstall then reinstall the HTC drivers. If that doesn't work your screwed.
Try this, its a program that tethers internet from your phone to your pc. It has all the drivers you can possibly need. I use it when I cant find the drivers to my phone online. Friends use this when adb devices dosnt show up with anything. Its worked for me 100% of the time. http://pdanet.co/ (just download the windows exe file and follow the directions. I believe you have to keep your phone plugged in during installation but I cant remember)

How about this. Put a nandroid of stock on your device. Plug it in the PC and create a folder called "clockworkmod" then inside there create one called "backup" now usually you have to move your nandroid to the root of your phone but if you use Philz Recovery, you can change the directory it searches for backups so it will be on your regular internal memory.
Drew recommended a flashing program for recoveries before. It was called Rashr.
Use that to flash Philz recovery.
Then just flash the nandroid and boot up.
Now remove root, flash a stock recovery, then relock your bootloader. Factory restore afterwards and your done.
Also, make sure if you factory restore that your nandroid backup never used titanium backup to remove any system apps as it might make your device act out with force closes. If you have done that either find a full stock with just root backup or use an RUU.
Done.

No "Yes or No" page when Unlocking bootloader!

Hello,
I tried to unlock the bootloader of my HTC Desire 816 Dual SIM, but the last step does not occur; that is, the page that should appear on the phone's screen and ask me to choose Yes or No (the page you see in the first attachment below), does not appear on my screen.
1. What is wrong?
2. Please help me to unlock the bootloader.
(Some points about the conditions my phone is in:
1. does not boot normally,
2. boots directly into Fastboot page,
3. in fastboot page I can select and enter Hboot page,
4. in Hboot menu, when I select Recovery, or Factory Reset, it only returns to Fastboot page.
5. as the attachment shows, the OS- is blank)
If you connect your phone to pc and select Fastboot, is Fastboot usb written at the top? Does your pc recognize the phone?
Have you tried flashing your original RUU?
For flashing RUU bootloader won't need to be unlocked. Just place your RUU zip on sd-card and it should flash the file on its own.

1. Yes FASTBOOT USB is written at the top
2. I have installed HTC Sync Manager; when I connect the phone, HTC Sync Manager starts but it says "no device connected". I think this is because the phone is not in normal mode but in fastboot mode.
3. I downloaded an "0P9CIMG_A5_DUG,... 2.34.401.2..." zip and put it in sdcard; it started to update but at the stage [1] BOOTLOADER, -FAIL-PU appeared and at the bottom of the page "Device halted due to Large Image". (see attachment)
Now I want to download "RUU_A5_DUG,... 2.34.401.1...exe" and I will try it. But before downloading, Let me ask the following question:
If 'adb devices' command won't work even if FASTBOOT USB is written on the phone, what does this mean?

Plz select another ruu from the link
If the command adb devices doesn't work, it's most likely not the snapdragon version. then the whole flashing process is completely different and most ruus you'll find won't work.

My procssor kind is: Quad-core 1.6 GHz Cortex-A7
The picture of the result of "adb devices" command I have attached.
1. You said "whole flashing process is completely different".
How is the flashing process for non-snapdragon version?
2. You said "most ruus you'll find won't work".
a. Do you know why? b. What kind of RUU might work for non-snapdragon version?

Sorry, I've had issues with my own phone the last few days( bad flash) and have been working to get it back to normal.
1. If you had the Mediatek processor like the 816g you would have to use the MTK toolkit to flash roms to your phone. Your device has a Snapdragon processor so that's not an issue. Nukaru was just saying if your phone wasn't responding to fastboot command then it might not be a Snapdragon but it is so your fine there.
2. No RUU you find will work unless it is the "exact" file for your version. These are signed files from the phone carrier/manufacture and they check your bootloader for the CID/version ID before allowing any rom to flash. Also trying to flash an older version of your rom than the one that was previously on the phone won't work. You can only flash either the last firmware version(401.2) or a newer version if available.
Your problem is twofold. Your phone's firmware is not readily available on the net and your OS seems to be either missing or corrupted with an unlockable bootloader. Unless you can either find or get your phone's carrier to find and give you the stock firmware zip/RUU so that you can restore your rom things aren't looking good and I don't ever like saying that trust me. Contact your carrier and request access to a flashable zip/RUU of your current rom. You haven't modified or changed anything on your phone so what can it hurt to ask? That's the best advice I've got without being able to unlock your bootloader.
Can my phone's lacking a ROM be the cause of non-appearance of "Yes or No" page (described in original post)?
Okay, was saving this for last. Please only post yes or no answers.
1. Are you a 100% sure your phone wasn't tampered with? Was the sealing intakt when you bought it?
2. Have you ever send your device to HTC to get it repaired?
3. Have you tried flashing another RUU before the error first popped up?
4. Did your device lag after you updated to lollipop?
5. Was this (drained battery) the first reboot after OTA update?
6. Have you installed all drivers correctly? HTC, java and adb? If you're not sure, try installing them again. After that try adb command again.
6. In which region did you buy this phone? Is it an Indian dual SIM version?

Can my phone's lacking a ROM be the cause of non-appearance of "Yes or No" page (described in original post)?

1. Yes. I am sure. because it was sealed.
2. Yes.
3. No. I have tried only one 0P9CIMG.zip and got "Device halted due to Large Image".
4. I am not sure. It worked a long time with 5.0.2 before the problem.
5. No.
6. java and adb are good. I have installed HTC Sync Manager successfully and when I connect the phone to PC, HTC Sync Manager starts but cannot recognize the device.
7 (actully). It has been bought from Iran. HTC middle east chat, told me that its Carrier is "Paratel FZE" which is in United Arab Emirates.

There's S off using the Sunshine app but you need to be rooted first and that means unlocking your bootloader thru HTCDEV first to root it then re locking your bootloader before running the Sunshine app which then unlocks it again. So basically the answer is no. Sorry.
1. Is it possible to flash bootloader?
2. My 0P9CIMG.zip fails at the stage "[1] BOOTLOADER". (look at attachment)
Why it stops at this particular stage?

1. Not unless your bootloader is first unlocked and the phone is rooted and you have the proper bootloader image to flash
2. Are you using an SD card that is formatted fat32( 32gb/64gb?) The larger 128gb cards are formatted exfat I believe. The file your trying to flash was never unzipped after download correct? If your transferring the file to your phone via your USB from your computer you might try using an SD card reader and remove your card and put it in the reader and transfer it from your computer to your card that way to ensure it got transferred ok(not corrupted in the MTP transfer.)

I think the bootloader of my device is ill or damaged, because rom zips or ruu.exe's stop just at bootloader stage.
How can I fix bootloader?

It's probably not because you've had no access to it as it is still locked. Even if it was damaged it can't be flashed over unless its unlocked and you'd need the correct bootloader image and that might be hard to find. Might be getting close to the time to consider getting another phone as your operating system is gone or damaged and can't find the correct ffirmware to flash back.

I have found the correct ruu.exe. The problem is that when the ruu.exe reaches the stage of "Rebooting to bootloader.........." (attachment 1) and sends the command to the phone, the phone is so slow in booting to bootloader that ruu.exe stops and says usb connection error.
I extracted rom.zip from ruu.exe.
Should I rename "rom.zip" to "0P9CIMG.zip" before putting it in sdcard?

HTC One M8 Shows the following message (Pic)

Hello guys,
My HTC One m8 (Sprint) shows this on the screen and refuse to hardr reset or do anything else. Do I have to install a new ROM ? if yes, which ROM can I install through SD card cause the phone isn't connecting to the computer.
Thanks guys,
Do you have custom recovery (TWRP) installed?
When you say "new ROM" do you mean a custom ROM, or do you want stock ROM (and for that matter, what was on there before it got "stuck")?
Do you want to try to keep data? If not, you can try to flash a Sprint RUU (and only a Sprint RUU), which may be the best course of action anyway, as it might fix the radio "INVALID" issue.
Thanks for your reply.
No I don't have TWRP installed.
I don't want to keep the data.
I need the phone to work, so I would appreciate it if you advise me which ROM should I install?
Thanks.
You can flash RUU 4.25.651.14. Either SD card method should work, or the .exe method. Your computer should still be able to connect via fastboot (which is how the RUU.exe works), even though it can't access storage. This is normal and expected - you can only access storage or adb while booted to OS or custom recovery TWRP.
RUU file and instructions here:
https://forum.xda-developers.com/showthread.php?t=2729173
Alternately, you can update to Marshmallow with RUU 6.20.654.3, but you will need to fastboot flash firmware 6.20.654.3 before you can run the RUU. Instructions on flashing firmware also on the linked thread.
Before you flash anything else grab the latest sprint RUU for your device, as already mentioned.

I downloaded the RUU that fits the number showed on the phone 4.25.654.14 on the computer and after few seconds it gave me error 171.
So I downloaded the zip file and put it on the SD card and it failed as shown in the picture attached below
Can you please advise what to do next?
Also : is there a software I can use to install the new ROM instead of the RUU.exe and Zip on SD ?
Thanks a lot.
Did you do anything to the phone to cause the current condition?
I would suggest trying other Spring RUUs, such as 3.31.654.2 or 6.20.654.3
Error 171 is connection issue, which you already somewhat mentioned in the top post. Connection issue is usually on the PC side. Try another USB port, another cable. Reinstall HTC drivers. Make sure the phone is in fastboot mode (fastboot selected in bootloader) when trying to do fastboot commands or RUU.exe.
You may also try to find the device in Windows Device Manager. Then pick the option to manually select drivers, and select the "generic" Android MTP device drivers. I sometimes have to do this, for my PC to "see" the phone in fastboot or adb.

partially bricked

I can get my Zenfone 2 up to the fastboot screen, but no further.
Under PC device manager is shows "Android-Phone" as the device, but no drivers loaded.
I've tried a few different drivers, but even though they seem to install OK, "Android-Phone" (in device manager) still won't show as having a driver.
Some threads say I have to enable Android Debugging, but how to do that when the ONLY screen I can get on the phone is fastboot??
Help???
Boowho??
You can try this.
1. Uninstall all drivers for phone you installed on PC, then reboot.
2. Disable antivirus on PC then install standard Intel android device usb drivers. You can download them from Asus website. Then reboot again.
3. Connect phone to PC in fastboot mode.
4. In the device manager you should see "Asus android device" under which "Asus android bootloader interface".
5. Check connectivity in minimal adb & fastboot software (you can get it from XDA) by command "fastboot devices" without quotes. It should answer "some number<space>fastboot".
If all is ok then you can flash raw stock firmware in fastboot mode & update it to latest version OR unlock bootloader, flash TWRP & install custom rom.
Thank you Sanesh. I got all the img/bin files successful now. However, the ZF2 has this issue when you select recovery from bootloader screen it gives dead android. You can then (extra step) hold power and VOl + and get into stock recovery. This is a flaw in the original firmware, I think.
BUT, this extra step is causing TWRP not to be entered. Stock recovery is OK, but not TWRP.
I had to recover the phone using the SOC drivers; before that TWRP worked perfectly.
Thanks
Have you unlocked bootloader ? Unlock bootloader first then flash twrp using giovix92 method. Then reboot to recovery.
Thanks. Turned out I was using a twrp image that is only for marshmallow. I still use lollipop. Every thing is now back to where it was before I had to recover the thing using the SOC method.
Lesson learned. un-root before trying to upgrade to MM.
