Hi everyone, I have a HTC Desire 820s running Kitkat 4.4.4 but there is a Taiwanese variant, the Desire 820ys which runs on Lollipop 5.0.2 and Sense 7 out of the box. Both are MT6752 MTK devices code named htc_a50ml_dtul.
I was able to get RUU zip for the Lollipop variant and thanks to nkk71 it was successfully decrypted without any errors. So I created a zip file using the boot.img and system.img and was able to successfully flash it with TWRP. The problem is that after flashing, the phone cannot boot into the system or recovery, HTC logo appears for about 30 secs, then it switches off for about 5 secs and the cycle continues(bootloop?). I could easily fix this with flashing kitkat boot.img with SP Flash Tool (cannot flash anything with the bootloaders in both phones )
What could be preventing the ROM from booting considering that they are of the same model hence no porting is required?
The boot file I extracted from the decrypted RUU was named boot_verified.img, does this mean it is signed or looks for some signatures before booting into recovery or system?
Thanks in advance

Dear all,
I am very new to android. I want to change better ROM for my HTC one s.
I have my S3 HTC one rooted with superboot following the below post from paulobrien
http://forum.xda-developers.com/showthread.php?t=1577831
I have installed Goomanager and TWRP recovery.
I want to flash the TrickDroid Rom as follows:
http://forum.xda-developers.com/showthread.php?t=1637102
As tell from the heading, it's compatible for S3 ?
But when I scan the Q & A section, it says "Do not use this ROM if you have an S3 processor based One S"
I m a bit confused for which ROMs are compatible for S3.
It also says " Relying on TWRP to flash the boot.img is not reliable. Please use the Boot_flash_script to flash the boot.img or do it yourself in fastboot. Having an incompatible boot.img is the common reason for being stuck at the boot logo.?
I have stupidly tried to flash it with the boot_flash_Script and it stuck at the boot logo.
is there any compatible boot.img specially for s3 processor which can run for the TrickDroid?
1. If the ROM is compatible with s3, how can I flash it ( I m just a newbie, really need those step by step guides)
2. are there any ROMs which are compatible with s3
3. is there any better method to root from phone in such a way that my phone will be compatible with most of the ROM [stupid enough]
4. anyone having the same case with me? [s3, root by superboot, Goomanager and TWRP]
5. I have flashed it with the boot.img from TrickDroid thread and it was stuck in the htc boot logo, fortunately i was able to boot it by superboot (from paulobrien). But then I cannot use switch on my wifi connection and I need to use superboot (through my computer) to boot my phone otherwise it just stuck at the htc logo.
Is there any method that I can restore my phone (restore to the situation before I flashed the TrickDroid) ?
Sorry, I should have posted this questions under the Trickdroid thread...but i m just too new to post in the development page.
Hey guys,
Recently I've tried to port CWM to my device following this tutorial and it bricked...
It did not boot in any mode (Recovery, Fastboot or Normal) after doing this (stuck on motorola logo/boot menu).
@diego-ch helped me and he managed to flash the XT920_2_290_2014 back on my device and unbrick it, but I want to install XT920_2_310_2014 back.
There are some Stock ROMs available on the internet, but these ROMs are outdated compared to my original ROM...
The ROMs available are: XT920_2_290_2014_A01_MP (Tim Brazil) and XT920_2_290_2009_A01_MP (Retail), and my original ROM was XT920_2_310_2014_A01_MP.
The backup script in this tutorial created a few files files: recovery.img, system.img, boot.img...
What I want to know is...
Is there any way to "reflash" these backups to my device?
Here is a printscreen from my original ROM:

And a printscreen from the "new" ROM:
https://dl.dropboxusercontent.com/u/82392755/NewROM.png
Thank you!

go on youtube type in how to adb sideload a rom on moto g that video will fix your problem well it did for me GoodLuck
Is recovery installed? Are the Moto drivers installed on your pc?
I've been through something similar before and whenever I accidentally wipe the OS, I just connect then flash another rom usually starting from here http://forum.xda-developers.com/moto-g/development/rom-stock-motorola-rom-collection-t2854688 and it will pop up under "my computer" where you can copy and try to flash your rom again. I assume it's the same with 5.0+ (I'm still on 4.4)
Which method did you use to flash lollipop?
i have a rooted Htc desire 820 with TWRP recovery installed
ihave also downloaded the OTA file from Xda forum about the lollipop update.
now i want to know if i need to update my phone into lollipop i just need to install the zip file thorugh TWRP recovery and that will work right?
and how can i install TWRP recovery after i have lollipop.
Please clear my doubts.
i have gone thorugh mostly every thread about my phone.
i am starting to lose hope here.
Please.:crying:

Everything else is stock (/system) and this image helped me recover another device which I softbricked by accidentally deleting /system
If you soft bricked your Sprint A9 by deleting /system like I did, boot to download and flash this image:
fastboot flash system system_image
The device will download and flash a couple of times for 5 - 10 minutes.

Can you help on this please?
I dont remember how exactly, but I think you just use the zip file. Don't unzip it on your own before trying to install. LMK if it doesn't work, I"ll try to look back adn remember.
