need a stock recovery to install otazip
[Desire 820 Android Development] YBS14881:
Otazip it self contains recovery img, You should download it and it will download in Download folder,you have to copy it in ex-sdcard and extract it.

Find it in firmware zip, flash through any recovery and don't forget to click on reboot after flash.

Thanks if you get helped.

This link worked for me.

I have some more doubts on this.

please help me on this.

I have restored the backup and when searching for updates a 70mb update is coming.

When trying to install it only goes to recovery (TWRP) and its not updating.

how to solve this issue.. Please help :confused:
[Desire 820 Android Development] harshad_kp:
The update cannot be installed on twrp recovery... You need to revery back to the official recovery... Since you have twrp recovery you must be aware on how to flash official recovery...

If the 70mb update filed is saved on your phone you can unzip it and find boot.img and flash it...

[Desire 820 Android Development] harshad_kp:
you cannot directly put it in the TWRP folder.

Try this

In TWRP folder make BACKUPS folder

Then inside that folder make another new folder name CC4CKYC04099

Inside that folder make another folder named 2015-03-28--10-42-44 KTU84P release-keys

THen inside this folder put all the extracted files

Then go in TWRP. It shld work now....

This is surprising... ne ways good it helped you...
[Desire 820 Android Development] harshad_kp:
What update.zip did you had on your sd card. This is a twrp back it should not create any update.zip. Maybe the update.zip prevented your phone from restoring the lollipop backup. If it fails again you can try deleting the .md5 files and then try again restoring the backup.

Hope you have used the latest lollipop twrp by posted by kinghunki.

Great for you!
[Desire 820 Android Development] Oel:

I think it works for you, because you flashed the firmware zip from the ota before?!

In the firmware.zip is the radio, Bootloader etc, so it can work on thies way. I am not shure, shall i make the sam thing?

[Desire 820 Android Development] harshad_kp:
you are not using the correct recovery. This backup will only restore if you are using twrp recovery. Currently from the picture I can see that you are using CWM recovery and hence you are receiving this error.
[Desire 820 Android Development] harshad_kp:
are you using twrp recovery or cwm recovery... this backup will not restore if you using cwm recovery.

Pls suggest correct twrp recovery to be used to restore the lollypop backup
[Desire 820 Android Development] Kartik13:
Actually I restored the stock backup from twrp that changed my build.prop file That is why my fingerprint and released key values changed .(that's why I'm not able to get 70 mb update it just goes to 990mb lollipop ota.)

Then I flashed stock recovery which then give me that error as shown in attached image.

So just I think that by pasting original build file (kit Kat 4.4.4) I will be able to install that ota .

so pasting that .prop file can make ota installation work if yes can u upload that file??

if no plz provide me solution.

Error show that I'm using htc_chs version but actually I'm using htc_asia_india version
[Desire 820 Android Development] Oel:
It can work. But i have the european version, you need a different build.prop.
[Desire 820 Android Development] harshad_kp:
you can directly flash a twrp recovery and then flash this twrp backup. I am sure there wont be any problem. Later you can revert it back to stock recovery of lollipop without any problems.

This worked Wonderfully

The Lollipop Backup worked like a charm on my HTC Desire 820 dual sim. working perfectly. I really cant thank you enough. :D :D

just an update: the release key folder (containing the extracted files) needs to be put under TWRP/BACKUPS/<device-name>

eg - TWRP/BACKUPS/SH4BTYM03048/2015-10-25--10-09-30_LRX22G_release-keys

the device name can be retrieved using adb fastboot command:

C:\adb>adb devices (when android/phone is started)

OR

C:\adb>fastboot devices (while under fastboot in bootloader)

example -

C:\adb>adb devices

List of devices attached

adb server is out of date. killing...

* daemon started successfully *

SH4ATYC03048 device

OR

C:\adb>fastboot devices

SH4ATYC03048 fastboot
[Desire 820 Android Development] filderge:
The Lollipop backup worked for me. The only problem is that, the system still detects it as something that is modified. Is s-on a factor why it does not work?

Btw, if you have a stock recovery for the lollipop backup, pls do send it to me, since the phone automatically deletes the downloaded ota update because it detects the firmware to be modified, thus, removing my chance of taking the recovery.img from such ota file.
[Desire 820 Android Development] RAMBOSAHA:
Hi Filderge,

The recovery was changed once, so it will always say "modified". Even if youre back to stock rom and stock recovery.

As for the srock recovery, do this:

Download the OTA but dont install

Download ES File explorer, go it internal storage and search for .zip or OTA. You should be able to see the OTA package. Copy it to sd or pc. Open it, open firmware.zip and extract the recovery.img

For me the file was 30mb so had to use htc_fastboot command to flash it.

Make sure you flash stock recovery first then relock bootloader if you want the OTAs. Because i spoke to HTC support team and they confirmed OTA will no way install if bootloader is unlocked.

Hope that helps! :)
[Desire 820 Android Development] filderge:
Hello, RAMBOSAHA! :) Unfortunately man, I don't even try to delete the OTA update, but the system simply deletes the update after verification :( Is there a way the system not verify the update so it won't delete the ota file? :(

Edit: it goes like this: Download OTA, then after I finish the download, the system automatically verifies the update, which then after verification, the system automatically deletes it 'cause it detects the system as something modified :( Maybe it has something to do with me, coming from a taiwanese version of the system?
[Desire 820 Android Development] RAMBOSAHA:
Are you opting "dont install" after OTA has been downloaded? Go for "install later" once ota is downloaded and it should work. Let me know if it still doesnt work, and ill upload the recovery.img for you.
[Desire 820 Android Development] filderge:
No sir, I don't even click the download, it just goes straight through verification after the dowload finishes... No choice to install or not...

Edit:

I think a lollipop RUU would solve this
[Desire 820 Android Development] RAMBOSAHA:
I searched a lot but was unable to find a proper Indian lollipop ROM for my htc 820. This one worked fine for me. Is yours A51_DTUL? You can reach out to HTC US support for help or browse xda forum for an RUU.

I'll share my stock recovery here for everyone if that helps. Please check back later today. I am running htc 820 having the Asia, India version.

I'm having the same problem. Android System, Android Kernel and Google Play Services use up about 25% of my battery together.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Galaxo60:
It´s not so hard to search:

http://xdaforums.com/droid-turbo/general/google-play-services-battery-drain-t3083672

:cowboy:
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Slartibartfast_:
The Turbo is still on Kitkat, not on Lollipop. And disabling sync is not a solution, it's merely a workaround (and it doesn't even work for everyone).

Specifically in my case, Play Services only take about 4-5%. System and Kernel take about 20% together.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] StormFreak:
I am having the same issues as well. Seems to have just started in the past week or 2... Wondering if its a server side issue, or an issue related to the new Google Photos? Specifically today, my battery is draining twice as fast as normal. Already tried deleting the cache partition. Considering doing a factory reset and starting from scratch....
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Galaxo60:
Android version doesn't matter because the problem is related to the Play Services which are the same for all, and yes, it's not a solution but a workaround for the excessive drain, because currently there is no solution and I doubt it will have one; it seems that this will be the behaviour of the Play Services from now onwards.

;)

The problem are the new Play Services, they are draining a lot the battery and they are working all the time while we are on mobile data. Something is really messed there, because this happens only while on mobile data, and on WiFi they behave pretty decent. Currently, I have around 3% battery drain with the mobile background data disabled, but if I enable the data, the drain is around 20% and let me tell you that most of the time I spent it on places with WiFi (Home and Job).

:(
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] bill0405:
Download wakelock terminator from play store. Add "Google play services" to the filtered apps, and paste this into the filter wakelock box.

NlpCollectorWakeLock

NlpWakeLock

CheckinService

NetworkLocationLocator

After doing this, I noticed hardly any battery drain and no functionality changes.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] distortedloop:
I don't see that app in the Play Store.

Does it require root?
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] bill0405:
I believe it does. Strange... But I just did a search and I don't see it in the store either. Perhaps you'd have some luck finding the apk on Google as they may have removed it.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Phobophobia:
This has been getting worse and worse for me over the last few days, even after wiping the cache from recovery. Today I've had my phone off the charger for 11 hours (on wifi the whole time, with a solid LTE signal), only 1:30 SOT, and the battery is under 10%. Google Play services has 4:19 CPU total and 3:19 keep awake., and is top on the battery stats with 38% (versus 16% screen).

I never thought I'd see Google be worse than Facebook at battery optimization. This is crazy.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] TechSavvy2:
Did you by chance do the wiping data of play services etc recently trying to check for lollipop updates? That causes sync issues (if you even did that). It's just odd that your battery life is so much worse than most people. I have my screen at 100% brightness all day, screen on time at 2h 47m and I'm at 68% battery left. My play services and Android system are both down at 3% each. And I've even been in and out of service all day. TBH I'd actually wipe your whole phone and start over at this point as you clearly have some abnormal behavior occurring.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Phobophobia:
Nope, just the cache (and only after the battery issues started). I have a lot of accounts syncing, but haven't changed my usage patterns at all recently, and until the last week or so I was easily getting 4+ hours of SOT in a 16-hour day with plenty left over.

I'm planning to wipe when 5.1 arrives, so hopefully we'll get lucky (relatively speaking...) and get it this week. Hopefully.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] pijes:
since you're on wifi most of the time, try disabling mobile data and restrict background data.
