memory problem

i had performed all the steps properly and my phone now has the stock lollipop given above...

now my phone "htc desire 820s" comes with 16 gb internal memory... when i had the factory kitkat 4.4.4 it had 12.4 gb usable and out of which 6 gb was always free...

now after flashing this stock lollipop i have 2 gb free...

if you go to the settings and select the storage option there you will find that the "system and other" are using 8.6 gb...

plz help as to why so much space is being occupied by the lollipop...

please help!!!!

what i think is that the "firmware upgrade" option on the sp flash tool overwrited the lollipop on the stock kitkat...

is this correct ???

Hello people,

First of all i am no developer, just a 11th grade(commerce) guy trying to do things on his own.

i am from India and i own a HTC Desire 820s Dual sim bought in Dubai, UAE.

It came at KitKat.

i rooted it using kingo root, it did root successfully and tested.

i flashed cwm.img using flashify.

i read all posts of all these threads:

https://xdaforums.com/desire-820/general/htc-desire-820s-dual-sim-lolipop-rom-t3142496/page15

I tried upgrading it to lollipop and was even successful doing it.

i used this D820S_LOLLIPOP_1.20.401.1_WWE.zip (downloaded it from the link given in the first post)

but did a small mistake doing it, i selected "format all+download" in sp flash tool, instead of upgrade.

it lead me loosing my IMEI (its blank).

i know that i need to go back to the stock kitkat (i am trying with this "D20S_KK_1.20.707.2_g.zip") to restore my imei but can't as the phone starts (normal boot, as its shut down) and sp flash tool shows the following error (image 1) while flashing.

while i was reading these threads i found 2 solutions to this issue (forgetting bad cable, bad windows, bad drivers, etc [i know all these are working fine] )

Solution A. 1. click on download button

2. press the vol up button

3. connect the phone holding the button

4. release button after the flashing starts

Solution B. 1. click on download button

2. press the vol up and down buttons together

3. connect the phone holding the buttons

4. release button after the flashing completes (The green OK symbol appears)

None of these solutions worked for me.

when i do it with solution A download mode (image 2) appears.

when i do it with solution B boot loader mode (IMG_20170310_192451) appears

in both the cases the error on SP Flash tool is the same (image 1)

there is one other thing i want to ask: what should be the position of the drop down list in sp flash-tool (Format All+Download/Firmware Upgrade/Download Only) while degrading to kit kat

i have a few other questions (these ones might be silly but kindly answer them, i genuinely need to know):

1. what is OP

2. what is s-on/off

3. what are these for "pgf-s"

4. What is MM

5. What is sense

6. ref post #129 of this thread by gibz97: i found some differences in this and "https://xdaforums.com/desire-820/help/desire-820s-how-to-root-invalid-t3281455"

[Desire 820 Android Development] Gibz97:
Are you using SP-Flash-Tool-v5.1532.00 from this link?

https://mega.nz/#!55cmxLzC!r-as99TN7AnpB2KQsUekf4a3TUkr2n88WHLd5SNM8E8
[Desire 820 Android Development] amirarsyad97:
1. Original post (first post) or original poster (person who post the original post)

2. Based on what I know, it is an extra layer of security by htc on the partitions so that it cant be modified. It is different from unlock bootloader or root. You can read more about it here https://xdaforums.com/showthread.php?t=1680928

4. Marshmallow i guess?

5. Htc sense, modified android skin for HTC devices

The rest I leave [MENTION=4951021]Gibz97[/MENTION] to answer it.

You cant unlock through the website.
[Desire 820 Android Development] Ranchoolal:
thank you very much for the answers

and yes i can't unlock it using the website (check the screenshot)
[Desire 820 Android Development] Ranchoolal:
at first i was usin this version (capture)

after u posted this (post #362), i downloaded it and tried again(capture1) , but again the same results
[Desire 820 Android Development] Gibz97:
That is strange. Does the volume up button work when you are booted into the system?
[Desire 820 Android Development] Ranchoolal:
Yup it does

Have u seen the video??
[Desire 820 Android Development] amirarsyad97:
When connecting to the pc, do you press the power button? Because that is the way you enter bootloader and download mode. Try pressing only the vol - and vol+, and do not press the power button
[Desire 820 Android Development] Gibz97:
Yes I have seen it.

Does the red light turn on before the phone boots into download mode when you try to flash it?

I could not see that in the video
[Desire 820 Android Development] Ranchoolal:
no i am not pressing the power button

---------- Post added at 03:52 PM ---------- Previous post was at 03:32 PM ----------

thank u for replying

yes the red light does appear for a second (the second in which "Download DA" gets to 100% from 0%)(the red progress bar)

there is one other thing that i noticed this time:

the first time i tried(here i mean now after i read your suggestion), i mean i when opened the SP Flash-tool it took a while to load the system.img(pink progress bar)

changed the drop-down list thing to "firmware upgrade"

clicked on download button

connected the phone while pressing only the vol up button

after a few secs the red progress bar appeared and instantly the tool gave error (it did not take 10 secs as i said in the video)

after that i gave it another try and it then took 10 secs (the 2nd try on the same tool already opened up)

also there is another thing, here when i released the vol up button it did not go to the download mode, it instead booted up

here is what i think

somehow whenever i connect the cable the power button gets active, that is why bootloader / download mode boots up after 10 secs

and here it did not have time to boot to bootloader / download mode so it booted up normally

i seriously need to get this done as its a friends phone
[Desire 820 Android Development] Gibz97:
What is the model name of your phone? It is usually found at the bottom back of the phone.

I think the problem could be with the volume button, it could have been connected differently from the usual Desire 820s.

(It could be the same model but that single unit could somehow have been connected differently)

That SP Flash Tool error means the phone's security (s-on state) is preventing flashing with SP Flash Tool, however for our phone that can be solved by pressing volume up and the phone's security is toggled to allow flashing.

Since that did not work, try holding all volume buttons together with the power button while connecting the phone to flash, try other button combinations as well.

And BTW have you tried using another USB cable?

Trying doing what I have suggested while I'm thinking of other ways to bypass the volume button.

However if you have access to a java card you can s-off the phone and flashing it will not require the volume up button pressing
[Desire 820 Android Development] Ranchoolal:
I have used 3 different cables on 2 different computers so that is not the issue

The back of the phone says:

Use only power supplies listed in the guide

Model: opoziod d820ts

Can you please explain a little more about that java thing, i have no idea about it
[Desire 820 Android Development] Gibz97:
It is a tool for turning security of HTC phones to off. It is found in some phone shops.

I will give you a solution that I have high hopes is going to work in about two hours as I'm currently caught up
[Desire 820 Android Development] Gibz97:
First root the phone with this app and tell me if it was sucessful

[Desire 820 Android Development] Gibz97:
If you want to write back imei you can easily use chamelephone app but the imei will disappear again if you factory reset the phone.

However if you want to permanently write the imei, there is way but it will be risky because your phone was not able to flash with SP Flash Tool
[Desire 820 Android Development] Ranchoolal:
Is it same as the engineering mode

And is there a way to find my original imei

Now i think i have bricked my phone

I tried flashing unlocked pgfs in op and now the phone is not even booting up

Just bootloader and download mode:confused::(
[Desire 820 Android Development] Gibz97:
That should be very difficult to get out of for you.

How did you try to flash pgfs? And was it successful?
[Desire 820 Android Development] Ranchoolal:
Using flashify, yes it showed flashing succeeded message and asked to reboot, since then it reboots to bootloader mode
[Desire 820 Android Development] Gibz97:
Did you flash them to the boot partition? because flashify does not have an option to flash the pgfs partitions.

If you did so, then you could have corrupted the boot partition.

You should have told me before doing that, I would have showed you how to do it with an android terminal.

Anyway, since it has already happened.

Now the only way to get out this mess is if SP Flash Tool can be able to flash the phone, have you tried rebooting the PC?

Try applying a little more pressure to the volume up button
[Desire 820 Android Development] Mohamed Yaser:
I use filezela client , which one u use
[Desire 820 Android Development] Gibz97:

[Desire 820 Android Development] joehanh88:
D820ts confirmed flash with this ROM. Thanks [MENTION=4951021]Gibz97[/MENTION] and others that behind the scene of this ROM. :D:D:D

but there is another update. how can i apply the update.? i have downloaded the update, but it fail to install. any other way to apply it?
[Desire 820 Android Development] PrateekBHT:
A few questions are arising in my mind:

1.) Is there any need to change CID of the device, since the Taiwanese firmware has CID as HTC_621 while my device, ie of Asia WWE has CID as HTC_044, so I am afraid that this should or not create any problem with SIM related features?

2.) Will my device Kernel v3.10.48 support it? Taiwanese 820s has different Kernel Version.

3.) Will I receive any FOTA updates, if available in future, for Taiwanese variant, with Lollipop installed that belongs to some other region, ie Taiwan, in my own region?

4.) Is it necessary to edit the partitions of the device before installing the firmware that you provided, since you posted that both Kitkat and Lollipop devices have different partition sizes?
[Desire 820 Android Development] Mohamed Yaser:
nice to see people interested , lets get a kernel specialist peps , we need a Premisive kernel
[Desire 820 Android Development] smartpal:
Cheers mate. I had the same doubts coz my device is also same as yours
[Desire 820 Android Development] Gibz97:
Have you tried redownloading and reinsatlling the OTA?
[Desire 820 Android Development] Gibz97:
The firmware will change your CID, kernel and partition table and you should receive OTA
[Desire 820 Android Development] PrateekBHT:
So, an Indian SIM will work without any problem. Am I right?

Also, does 5.0.2 has screen mirroring option inbuilt?
[Desire 820 Android Development] Ranchoolal:
Yes i did flash them to the boot partition..

Yes i have been trying to use sp flash tool since then..

Applying different methods..

There is one another thing:

I googled about sp flash tool alternatives and found a software "mediatek flashtool" it says that the scatter file is invalid.

I have even tried removing the battery, but that's too not helping

I would rather donate u guys a few bucks than giving it to some tech shop...
[Desire 820 Android Development] Gibz97:
It's the same thing as SP Flash Tool.

There is still hope, turning the phone to S-off will definitely solve the problem as SP Flash Tool will be able to flash.

One more thing can you send a screenshot of the drivers you have installed?

Control panel > Device Manager
[Desire 820 Android Development] Ranchoolal:
Hi

I finally found a way to flash the phone.

I think the issue was with the drivers.

I had a zip of the drivers saying "All MTK drivers 2014"

I extracted it.

When the computer asked for drivers i had it search the entire "All MTK drivers 2014" folder.

This time i formated my computer and did this:

Opened the "All MTK drivers 2014"

Copied the drivers for MT6752

Pasted them on desktop then had it search the desktop. It worked !!!!

I would love to thank everyone, specially gibz97.

Thank you very much

There is still a small issue

I do not know whats my imei number

I am right now on kit kat

Even i somehow get them do i have to use sn write tool?

---------- Post added at 09:46 AM ---------- Previous post was at 09:08 AM ----------

I fortunately found one of them on google dashboard, but how to flash it
[Desire 820 Android Development] Gibz97:
I am glad you have finally solved the issue.

Yes, to permanently write the imei you have to use SN Write tool using my guide.

You can find the original imei on the box that came with your phone.

If you don't have it then you can use random imei generator from here https://dyrk.org/tools/imei/

Sim problem

Good day. I have a problem with my HTC Desire 820s. It came with android 5.0.2. But I have a sim card problem, only the radio of the sim on 3g/4g comes on. The other radio stays off. No one seems to have this problem so I reflashed the lollipop ROM from this thread. But that didn't solve my issue. I want to know if this can be a deeper software problem or a phone hardware fault. I plan on flashing the KitKat ROM on it soon. But I decided to ask you guys for you take on it. [MENTION=4951021]Gibz97[/MENTION]

does it matter?

The Firmware is strictly for Desire 820s which has MediaTek CPU.

Desire 820u has a Qualcomm CPU that's why the PC cannot recognize the hardware as MediaTek

[Desire 820 Android Development] Gibz97:
That happens when SP Flash Tool gets interrupted, could have been due accidental cable disconnection.

Keep the phone connected to a wall charger for now, it will power on after some hours, 15 to 20 hours.

Then flash it again, but this time hold the volume up button while connecting phone to PC to flash
