Hi

Please if someone can help me your most welcome to reply to me.

I unlocked the bootloader on my phone via htc dev and installed twrp recovery via fastboot. Every thing went perfectly well until I tried to get into the recovery mode in order to flash a custom rom. It displayed on the screen entering recovery but it got restarted and did not go into recovery. I flashed the recovery image again via fastboot and now it is stuck in a boot loop and I cannot use my phone as the dialler is not working and it is not picking up any mobile carrier. It starts up and rest you can see in the images(please send me your email so that I can mail you the pictures). I can't even turn it off and keep it turned off because when I long press the power button the home and the back button at the bottom keep blinking and the power menu does not show up. Please help very it will be very much appreciated.........................!!

How do i do this on my phone pls help
[Desire 820 General] ray.77141:
I don't have the device anymore, but last time I checked HTC Desire 820 Dual Sim Indian variant (A51_DTUL) already got marshmallow update. So if you already updated your device to android marshmallow it is not a good idea to install downgraded RUU. If you are still using Android lollipop in your device, you can install this RUU. But I would recommend to install an updated RUU (android marshmallow). You can search for RUUs in google or xda forums. You can follow the instructions from OP of this thread. Try to flash the RUU using your phone, not with your PC. It's easier and safer.
[Desire 820 General] Shrey@s:
It runs on kitkat..... Its got other problems too... No update option in settings.... N

I had MM firmware and everything went fine upto installation of twrp v3.0.2-0. After that I tried installing KingSense MIUI 7 (based on 4.4.4) for my d820u and it resulted in a bootloop. From there onwards my hboot installation of the same firmware does'nt show any errors but says "press power to reboot". From there it just goes to htc display and nothing changes. I hope this RUU would solve any issues. (yes, i did relock bootloader)

Does this method help me.I need lollipop in my 820.

Please help me.

Thanks.
[Desire 820 General] h1dd3n_sn1p3r:
- 1st thing never ever go for OTA update if you have Custom recovery .

- 2nd thing if i am not mistaken you must be running KK

- 3rd U are htc 820U A51_DTUL & You are free to go through this process..

*Important*

Go to recovery & make complete backup of current ROM if incase some thing goes wrong

_____________________________________________________________________

- Read the steps follow the process :good:

- Do let me know if anything i can assists!
[Desire 820 General] friendlynandy:
Thanks.

But I tried OTA update before I unlocked and installing a custom recovery .

And yes I am running KK

I also have that 300 mb downloaded zip file can i some how install it through twrp.
[Desire 820 General] h1dd3n_sn1p3r:
Mate You cant make OTA system update with custom recovery. You will stuck at loop

- forget about 300MB file

- follow that all process

- before doing anything i recommend you to make TWRP backup of ur current ROM

- Proceed with out worries
[Desire 820 General] friendlynandy:
Hi done everything you said. After I downloading 70 mb it throughs same error modified system . Please help.
[Desire 820 General] h1dd3n_sn1p3r:

Hi , I installed Lollipop. Everything is fine but after a use of 4 days I booted into recovery which is TWRP Recovery 2.8.7.0. Now its not getting rebooting normally. I mean when I try rebooting into System or boot-loader or switch-off from TWRP reboot option its getting back to only TWRP. I also tried using power button and volume button. I tried every possible way I know.

After a long I tried restoring the Lollipop backup then after its completing the restoring processes I got a option to reboot I done that and it rebooted normally into in system. But I tried again to go to recovery now the same problem its not rebooting into system. i also tried changing the TWRP . But no use. Please help.

Thanks.

To be really honest i'm confused since days (somebody too asked for this issue here in forum) that why HTC desire 820U is using bootlodder of HTC desire 816 .

- what is this actually is module number mistake or the bootlodder ?

As per info this is http://www.easy-firmware.com/index.php?a=browse&b=file&id=1462 Ruu but it's for 816!

-before doing anything contact HTC support what actually is this problem

Is the MID correct?
[Desire 820 General] h1dd3n_sn1p3r:
Looks like you made a simple mistake.

Can you re-name the downloaded RUU and rename it to "0PFJ11000" & then put in SDCARD . now reboot to the bootlodder it must auto detect the file
[Desire 820 General] fshami:
Thanks for your guide & reply. Well i am able to reflash 1.22.720.1 while keeping the RUU named as 0PFJIMG.zip in the sdcard. After setting up the phone, it prompts for an update 1.22.720.10. It downloads it but while trying to install it gives an error of Wrong Variant & i cannot update the phone.

Then i downloaded the Android L OTA file also containing 1.22.720.10 firmware.zip.. file name is OTA_A51_DTUL_L50_DESIRE_SENSE60_MR_hTC_Asia_India_2.10.720.1_R-1.22.720.10_release_453049wea2pi2o56gw96qr

I renamed the file to 0PFJIMG.zip. Fastboot detects it but when it starts Parsing immediately it says Press Power Button to continue & the phone reboots without being flashed

I extracted firmware.zip from the above OTA & flashed it via Fastboot. At the bootloader / fastboot screen it shows 2.10.720.1 & then the phone boots into recovery & returns error sota file missing & the phone keeps booting between bootloader & recovery

Then i tried to flash the OTA file using fastboot & get this error:

C:\adb>fastboot oem rebootRUU

... (bootloader) Start Verify: 0

OKAY

Execution time is 31(ms)

C:\adb>fastboot flash zip firmware.zip

sending 'zip'... (1014237 KB) OKAY

sending time = 54.003 secs

writing 'zip'... (bootloader) zip header checking...

(bootloader) zip info parsing...

FAIL24 parsing android-info fail

FAILED (remote: 24 parsing android-info fail)

Execution time is 68(s)

Does it have anything to do with the MID? What is the MID of your device?
[Desire 820 General] h1dd3n_sn1p3r:
Forget about CID & MID coz you are S-off & have super cid 11111111!

Looks some thing error that i can't figure-out ATM.

You are telling that RUU flashed & phone got started that means that you should be able to make an OTA update from setting>about>software update of phone without any issue but could't understand here why it threw an error.

Hope you will not mind if i tell you to upload your current bootlodder snap
[Desire 820 General] fshami:
Hi there, after 2 days of headache to rectify the issue. I've identified the exact cause & found the cure :). Testing it right now on the device i have.. will post a guide once i fix this device..
