Hi there

Some guys are having issues installing Google apps on their 820us devices(after flashing it with stock rom),can they use this TWRP recovery to flash the zip Gapps file onto it?
[Desire 820 Android Development] Gibz97:
Yes it can install GAPPS package
[Desire 820 Android Development] amirarsyad97:
Will this recovery work on lollipop rom u have made? If do, how?

1. Using flashtool, rename twrp img to recovery.img, put in rom folder, and flash it. Or

2. Unlock bootloader?
[Desire 820 Android Development] Gibz97:
These versions only work in Kitkat. The Lollipop TWRP will be uploaded soon
[Desire 820 Android Development] Gibz97:
Lollipop TWRP uploaded; OP updated
[Desire 820 Android Development] amirarsyad97:
It has been a while since the last post. The aroma installer and aroma file manager seems not working. I opened opengapps aroma installer and it stuck at the start. The only way is to reboot. I'm using lollipop twrp wwe. Also, [MENTION=4951021]Gibz97[/MENTION], can you update the base to 3.0.0?
[Desire 820 Android Development] Gibz97:
The version of aroma installer before the latest one works on our TWRP.

I already have the base for TWRP version 3.0.0-0. I will work on it when I get the time
[Desire 820 Android Development] Gibz97:
OP updated TWRP version 3.0.0.0 for Lollipop links added
[Desire 820 Android Development] Vivacity:
Will you make a version for other htc variants? 820u for example..
[Desire 820 Android Development] Gibz97:
I don't own that device so I cannot test, but I can try it if I get your stock recovery and someone willing to test
[Desire 820 Android Development] Vivacity:
cool i'll send you the stock recovery asap. and i will test it too.
[Desire 820 Android Development] Vivacity:
here it is. https://drive.google.com/file/d/0B54pSHVzMLHQYU9ya3pubEFuTW8/view?pref=2&pli=1

PS: on the version of twrp i am using right now there is only one bug, it keeps rebooting in recovery when you restart the phone from an app.

[Desire 820 Android Development] m0han:
hi guys,

i've got hold of an htc desire 820 Dual SIM phone (India).

i'm not familiar with 'fiddling with' htc phones.

please help me root and install twrp recovery on this phone.

[MENTION=4951021]Gibz97[/MENTION], [MENTION=5111518]Vivacity[/MENTION], how do i get stock recovery out of this phone? :o

btw, what other name is this phone known by - like D820s / D820ys / D820ts / D820us?

p.s.: if this is not the right thread, please point me to the right one. thanks.

I tried this on Desire 820s [Lollipop WWE]. On the 5th step when I give the command it says "waiting for the device" & nothing beyond that.

How to overcome this? Please help.
[Desire 820 Android Development] Gibz97:
It is a drivers issue, try using another USB port
[Desire 820 Android Development] kav4:
I updated my 820s to lollipop & installed TWRP as well. After that I tried to restore my SMS backup through Titanium Backup. But instead of SMS I have restored, phone dialer. Then it started giving me error message every 2-3 seconds without letting me do anything on the phone. Also it stopped detecting the network. Then I reboot the phone to TWRP & instead of doing a data wipe, I have selected "system" wipe.

Now the phone does not boot. It stay at white HTC screen & does not go beyond that. I have to wait till the battery fully dead to make the phone off. I tried to reflash Lollipop through sp flash tool but it does not let me. Can you please let me know what can I do to correct this?
[Desire 820 Android Development] Gibz97:
Press and hold volume up button while connecting phone to PC and continue holding until SP Flash Tool starts to flash.

Next time please either post or send private message, don't do both. Thank you
[Desire 820 Android Development] kav4:
Sorry for the delay. I had to wait for the phone battery to fully down & then recharge half to test. That was because the phone was stucked & I could not power off to test. After sending the private message, I thought you may not look at them. That's why I posted here.

Anyway now I have fully flashed the lollipop & it's working fine.

Thank you for your time.
[Desire 820 Android Development] gonz1:
Hi, my situation is that my device is rooted, (i used kingoroot) and i have flashed cwm recovery, I am unfamiliar with the term "unlock bootloader" does this mean having a custom recovery? and is cwm ok to proceed with these steps? or should i use twrp? if so would you know how i can go about changing it to twrp? thanks for any help
[Desire 820 Android Development] Gibz97:
Unlocking the bootloader is only necessary if you are on Lollipop, if you are on Kitkat you can just flash TWRP and it will replace CWM and does not need unlocking of the bootloader
[Desire 820 Android Development] gonz1:
Ok now to flash TWRP which option under 'Downloads' should i proceed with? The 3.0 820s (Lollipop WWE)?
[Desire 820 Android Development] Gibz97:
If you are have lollipop download version 3 but if you have KitKat download version 2.8.4, it's clearly shown in the downloads
[Desire 820 Android Development] gonz1:
Ok ok sorry my thinking was i have to download the one that i want (eg i want to have lollipop on my phone so i choose the lollipop version). After i flashed twrp what is the next step?
[Desire 820 Android Development] Gibz97:
If you wanted to flash lollipop then there is no way you can flash it with TWRP you have to flash it with SP Flash Tool using this thread http://xdaforums.com/desire-820/development/stock-lollipop-5-0-2-ruus-guide-mt6752-t3279089

Hi, sorry this is another topic I want to know if I bricked my 820s or not.

I need some help. I just got this device 820s it's running Kitkat (already rooted). I flashed CWM recovery from this thread:

http://xdaforums.com/desire-820/development/desire-820s-root-cwm-recovery-stock-t3251639

I follow this instruction and use Flashify to flashed the: cwm-recovery-htc_desire820s.img

Install CWM Recovery:

1. You must have your phone rooted

2. Download the recovery here : cwm-recovery-htc_desire820s.img

Then you can :

Use flashify to flash it.

After flashed I rebooted it as normal to enter recovery. But the phone turn off/got black screen I think during try to enter recovery. Since this happen I cannot charge or power on the phone anymore. No led light when plug in charger or plug in computer.

Is it a brick? I have other phone G2/G pro2/Htc one M8. I never seen like one this even brick we should power on the phone to boot it.

Also Since I got this phone last week I was having problem the phone cannnot charge and cannot power on. Then yesterday somehow it can charged (battery was 0%) and power on for the first time ever. I charge to 100% and use it coupple of hours before flashed the CWM recovery, now look like it's dead again.
[Desire 820 Android Development] Gibz97:
Have you tried flashing the stock firmware with SP Flash Tool?
[Desire 820 Android Development] Moon75:
Hi, thanks for the replied.

No I haven't try to flash stock firmware. The thing is the phone cannot turn on, not show led light or anything when connect to charger. It's not show when connect to pc via usb cable either. When connect to pc I tried press:

- Volume down + Power button,

- Volume up + Power button

- Volume up and Volume down + Power button. None of these combination is working so far.

I mean at least it should have power, can turn on even stuck at HTC logo or bootloop etc.

Anyway I will check out the SP Flash Tool, thanks
[Desire 820 Android Development] Gibz97:
If the PC can recognize the phone by producing the connection sound, then you can revive it with SP Flash Tool, but if it does not then it is likely a hardware issue
[Desire 820 Android Development] goldenevil47:
Hey bro i m unable to install recovery in 820s...i flashed TW lollipop and unlocked pgfs files as well..but when i type command to flash recovery it does nothing and is stuck on WAITING FOR DEVICE...even the fone is in download mode..plz help
[Desire 820 Android Development] Gibz97:
its a drivers issue.

You can flash with SP Flash Tool. Rename recovery to recovery-verified then place in flashfile folder then tick recovery only on SP Flash Tool then flash
[Desire 820 Android Development] Moon75:
Hi, thanks for your help so far. I tried flashed with SP flash tool, it got sound when flashing, I got this error so far:

BROM ERROR: S_FT_ENABLE_DRAM_FAIL(4032)

[EMI]Enable DRAM Failed

[HINT]

please check your load maches to your target which is to be downloaded

I attached photo of the error. SP Flash tool show my phone as MT6752 on the left side, that mean my phone use this CPU right?

My phone is DUAL SIM, I downloaded this firmware and try to flash:

STOCK KITKAT FIRMWARE LINKS

Desire 820us

And this LP firmware, tried to flash got same error as the Kitkat stock firmware:

D820s_LOLLIPOP_WWE (EUROPE WORLD WIDE ENGLISH FIRMWARE), Build 1.20.401.1

What driver under computer device manager I should have, now I got:

- Mediatek DA USB VCOM port (COM5)

- Mediatek Preloader USB VCOM port (COM10)

- Mediatek USB port(COM14)

I bought my phone from here: https://www.fastcardtech.com/htc_desire_820us_dual_sim.html

I guess I tried to flashed the right firmware, like D820s_LOLLIPOP_WWE, it would be ok for D820s/D820us.

For Kitkat I teied both for D820s and D820us but not working so far.

[Desire 820 Android Development] Moon75:
Hi, thank you for your help. There is no model number on the back cover or anywhere on the phone. I forgot to check using software when it was working. I order the D820us with CPU MTK6752 but I check on the back of the phone box and plastic screen protector it said D820 with CPU Qualcomm Snapdragon 600. But I can't be sure it's refurbished phone they might just use the box.

I am asking the shop I bought from what did they send to me: D820us (MTK6752) or D820 with Snapdragon 600.

It seems like the SP flash tool flashing error tell me it's wrong firmware I was flashing, may be.

If the phone is D820 with Snapdragon 600 that would make sense. I need to find it out first I guess.
[Desire 820 Android Development] Gibz97:
It's an external sdcard issue, FAT32 file system supports a maximum file size of 4GB only and the system image you would like to backup is 4.4GB.

You either need to backup the system image to your internal storage or use an exFAT formatted external sdcard
[Desire 820 Android Development] m0han:
i'd like to know whether the card would be read while connected to pc (through data cable or card reader).

fyi, a usb disk (8 gb) when formatted as exFAT was NOT read by the phone when connected using otg cable.
[Desire 820 Android Development] m0han:
please help me with the issues i've posted about here. logs & screenshots here. thank you, [MENTION=4951021]Gibz97[/MENTION], [MENTION=6891123]iSaidyiu[/MENTION], [MENTION=5071796]Kellwa[/MENTION], [MENTION=3834462]QkiZMR[/MENTION]
[Desire 820 Android Development] Kellwa:
I think the problem is that the sd card is fat32 formated and this type does not support large size in single file like system image your trying to backup

If you want that system image backup it to internal and copy it to your pc

Because you only can use using fastboot i think wich mean you have to copy to pc anyway
[Desire 820 Android Development] Moon75:

So, I got a small update just now for my N900T. The changelog says OS 5.1.1.

I'm installing now. Will update when it's finished.

Edit: Added screenshot.

Build number is N910TUVU2DOK2
[T-Mobile Galaxy Note 4 General] blindskater39:
I have a update downloading as well, lets see how this goes. You meant to type N910T I presume?
[T-Mobile Galaxy Note 4 General] Techngro:
Yes, I know the N910T3 has had 5.1.1 for a while, but no, this is for the N910T.

Unfortunately I am not rooted, so I can't provide any firmware dump or anything else that would be of help to devs. :(
[T-Mobile Galaxy Note 4 General] blindskater39:
I have the N910T as well. I am not rooted either for now... How did you view the changelog?
[T-Mobile Galaxy Note 4 General] Techngro:
When the install finished downloading, it asked me to confirm the install. That's when it showed the changelog. I should have taken a screenshot of it. Probably had good info. Oh well, too late for that now.
[T-Mobile Galaxy Note 4 General] blindskater39:
I got you ;) I hope this doesn't cause any troubles for rooting.
[T-Mobile Galaxy Note 4 General] twister99403:
My phone just started downloading an update as well. Couldn't find what update it was downloading until I came here. Hopefully no issues?
[T-Mobile Galaxy Note 4 General] Techngro:
Haven't played with it enough yet. Time for bed. Have to go to work in a few hours. But the install went smoothly, and the first boot was fine.

Let's hope it stays that way.
[T-Mobile Galaxy Note 4 General] Techngro:
Thanks. Security update. Yaaaaaaay!

As for rooting, I'm sure the usual suspects from XDA will be on it in no time. They'll probably have root before I get home from work. :)

Bars don't mean anything. What's the change in dBm under settings/about phone/status/signal strength?

Might not mean much but having any signal vs no signal is an improvement.
