Hey kinghunki you hav ported sense 7 in the past ,can you do the same with sense 8

That would be great
[Desire 820 Original Android Development] AeonWorld:
@kinghunki

Thank you very much, Its hard to find good devs like you in here. Well I havent flashed it :D , but to know its here is a big relief.

My phone have an issue now, bootloop at optimizing apps ( official android 6 ) looks like a corrupt install, correct me if am wrong, I tried everything wipe cache,data factory reset..., and since its 6 , i cant find any RUU , is there anyway to fix this, even if I find the culprit app I wont be able to remove it, no root. But since warranty is over I can unlock and root if required.

And for strange reasons factory reset doesnt show a progress bar, the phone restore symbol turns but usually there is a progress bar ( was when was in 5 ) its not there.

I have a lollpop firmware in hand, but will downgrade be possible? does it come with a stock rec? will adb firmware flash be able to downgrade?

please help me out, I like to think I'm not a noob so throw me anything you have in mind.

Htc desire 820u (Q615) android 6.0.1 official update. And yes I do get past the optimizing apps sometimes ( very rarely ).

I'm new to HTC family.

Thank you,

Aeon
[Desire 820 Original Android Development] tomal:
Welcome to HTC family.

From MM to Lollipop downgrade is feasible but I suppose yours may not work. It has to be custom made.

Anyway, do it as follow -

- unlock your device

- flash custom recovery from this thread

- wipe cache, dalvik-cache, android-sec, data including internal sd (take sd backup if required)

- reset the device
[Desire 820 Original Android Development] QkiZMR:
I'm already updated to 6.0.1 but didn't test if it's work properly. I always enter to recovery from bootloader.

1. Go to recovery mode(

It must be set TWRPrecovery )2. Then go to wipe

3.Then go there and format data "yes" type and press the Enter key

4. After the go ahead to wipe wipe partition, and then ... chache, delvik cache

System, data, internal sd ..then wipes

5.then restore your backup twrp

6.after install backup Ur perform factory reset to wipe section.

7.then again go into formate data section to wipe it "yes" type and press the Enter key

8.now preess system reboot. PS This can help
[Desire 820 Original Android Development] AeonWorld:
Thanks for the info, but none of em works. Currently custom rec.

I'm gonna root and remove almost all apps, see if that works
[Desire 820 Original Android Development] vuk1963:
Okay
[Desire 820 Original Android Development] AeonWorld:
Anyway found the solution & issue.

Its the CPU temp, the choke point is set to 60 deg, which basically was not there! (or wasn't there that much heating before?) , and when the phone switches on, the temp rise up due to high brightness, blah blah..., and drain battery causing more temp, so it restarts before it can complete, I put it close to the A/C and it completed. Donno why, I never had this issue before. The best part is I rooted and unlocked the phone for no reason whatsoever :D :D , well I guess I will have to find a way to make updates available, using stock ruu when it hits XDA and methods from fine devs in here, S-Off still not available :(.
[Desire 820 Original Android Development] medohatem:
anyone know how to do that ? :confused:
[Desire 820 Original Android Development] QkiZMR:
Stock recovery is in OTA file.

Wysłano z Tapatalk / Sent with Tapatalk
[Desire 820 Original Android Development] AeonWorld:
You can try this,

Boot TWRP without flashing, (hot boot) i think the code was

fastboot boot YOUR_TWRP.img

then backup the recovery using twrp. Well thats the theory, I forgot to do this and I feel really really bad :( , thus I dont have stock MM recovery, now MM is running on lollipop (stock) recovery. I forgot am using htc desire 820, :D stock files don't hit here fast you know.

Note the code DOES'NT have "flash", DONT accidentally add that

After you backup please upload that here.

I flashed TWRP for M and then flashed superSu might be v2.46 and i got stuck at bootscreen. Bad Luck is i had not created backup for my Marshmallow Rom.

Is there any way to solve this issue.

[Sprint LG G4] Rally187:
So I downloaded an app while waiting for my wife to get to the gym and noticed that it downloaded instantly. The app was 40mb. I was curious and had time so i did a speed test, I was getting 96mbps which is insanely fast compared to my 9mbps dsl connection at home. So my question.... do you think i could get away with downloading large files? I was thinking about using it to download steam games when i bought new ones, seeing as how my ATT dsl connection recently got limited to 250gb per month. I would just tether to my laptop and let it download while working out. No torrents, nothing shady, just steam games so it doesnt take up my home data.

How crazy is it that my cell phone has unlimited data and my home internet is limited. What a world huh?
[Sprint LG G4] KingFatty:
Would sprint just throttle your speed to very slow? If you download lots of data, i think they would slow down your speed. So they can still claim you are unlimited, but just very slowed down so you can't really enjoy it, assuming you are pushing your luck if you download multiple gigabytes of steam data in a short period of time.
[Sprint LG G4] andrewwm:
Sprint could deproirtize you ab 23 GB but it won't lose speeds. They will make you a lower priority but still good speeds.

Go ahead and do it, good you are getting 96 Mbps.
[Sprint LG G4] DominicGresham:
Sprint actually doesn't thottle

I been using sprint and they don't throttle on the LTE+ network
[Sprint LG G4] QuickNET Tech:
What plan do you have? Is it the truly unlimited one or one of the ones where they offer 'x' gigabytes before they slow you down to (I believe) 2G speeds. If it's truly unlimited, then you will be fine, just note that you will be "deprioritized" when you surpass 23GB of data usage in one billing cycle and when you are in an area with lots of traffic putting strain on the network. This is barely noticeable 99% of the time from my experience as I often use close to 100GB/month. For more information on this, including why they do this, see HERE. However, if you are on a plan that is throttled after 'x' GB, do not do it. 2G speeds are nearly unusable nowadays. Say goodbye to all video streaming. Pictures will load s l o w l y as will everything else, including basic html websites.

If you are unsure of your plan, see the main page within the Sprint Zone app.
[Sprint LG G4] andrewwm:
What the crap, over a TB a data? What does it say on the Sprint Website?
[Sprint LG G4] DominicGresham:
it says the same usage xD they really dont throttle like i said

---------- Post added at 08:10 AM ---------- Previous post was at 08:07 AM ----------

the only time they throttle is if the towers are being upgraded so they can keep consistent speeds to the lte+
