Got the latest build from Patrik from January running on my Girlfriends device. Its used for backup now with a fairly light setup, works just fine and way smoother than the kitkat that she got it with. These days many of the apps dont play to well with old android versions anymore.

As for the kernel. I remembered the days when I had a samsung galaxy SL i9003. And that one didn't get kernel 3.0 which was a huge problem getting ICS 4.0 to work correctly. Eventually, dhiru1602 built a kernel 3.0 by himself and incorporated all the necessary samsung code. The device lived on and received a good stable CM11 in the end. Today someone is working on an omni-rom based on 7.1.2 nougat. Just impressive.

If you find someone with some time and kernel knowledge to help you i think it could go very well.

You are very motivating [MENTION=4650658]felixchris[/MENTION] , This is my first time doing a big project like a device so I have 0 experience, but I think I can make this work. It's amazing that someone got a phone that wasn't kernel 3.0 to kernel 3.0 .

I think I am having a much bigger problem on my device. I built cm-14.1 and cm-13 but they didn't boot and booted straight to fastboot, now I made a cm-12.1 just now and now It still boots to fastboot. Can you provide me with a working patrik build? I would really appreciate it if you have one handy. I think it's just my device. Also, We should find more people that have HTC Desire 620's or even ask a Administrator to make a thread for our device. Maybe we should make it in a HTC Desire 510 Device Thread. The more people we get, the faster we can make this for our device and the better support we can give it......

I was watching Google IO and saw that they are making "Android Go" which is a platform that runs on devices with 1GB or Less for optimum performance, If we can get this done, It would be interesting to make Android Go 8.0 O

Can you tell me if this build works IN your free time, I'm not in a rush and it probably wont work so have a backup of your data and/or another copy of OpenGapps and the latest patrik build.

Hi Liam,

Unfortunately I have no device at my hands right now. My GF gave it to a friend that uses it daily now, since he broke his entirely.

I'm uploading you the exact build and gapps combo I used to drive, since I didn't want to bother searching.

I used the newest twrp that you can get from their site twrp.me

Be sure that your bootloader didn't get relocked or something.

Also I started off a clean device. The unlocked Europe version. I did it with the HTC Rom zip on the SD card called some 6 or 7 characters. It automatically loads then, takes forever and you then have a fresh, debranded device to start with.

Not sure if that does anything but well. Too often things are as trivial as wiping everything in twrp when you flash, being on the right Firmware to start, different recovery versions etc.

So try if you can get patriks build running. If yours then fails with the same procedure you know that's the culprit and move on from there.

Keep it up!

I just wanted to let you know I have tried your build. It boots to fastboot for me too. I have tried dirty flashing over patrik build (20160121) and also clean flash through TWRP, but neither did work.
[Android Q&A, Help & Troubleshooting] liammendes:
Unfortunately I just to figured out why perfectly fine older builds do not boot on my phone. I have tried patriks build hut it still boots to fastboot. This is due to the NFC module being broken (the two pins at the back above the battery is broken allowing the phone not to boot on any builds. I therefore can't continue trying to make builds on a phone that doesn't work on working builds. HTC Desire 620 is not dead yet and I think we are just in time for Android Go - O 8.0.0. But until now I think this should be postponed. If any developers want to try taking on this project theirselfs, the device tree is good, you may just need to change a few parameters from cm12.1 to los 14.1 such as MALLOC in one of the make files. The really challenge is and has always been the kernel in our case. The kernel is too old therefore it needs to be updated to be compatible with the latest code from Qualcomm. One of the updates that need to be made is to upstream the kernel to 3.10.49 (I think around there would work).

Okay, here is a TWRP to help you get permanent root. It is not stable yet, i will fix all the bugs later.

https://drive.google.com/file/d/0B5KRmU8P96dld3NkTkNCTzc0X1k/view?usp=sharing

This is only a port from Yureka's official twrp 2.8.6. I have some problems with building from source (screen turns on and off repeatedly), but I will try to do so asap.

Bugs:

- glitchy colors on first screen poweron - you can get rid of them by waiting till the screen turns off and then press the power button

- no offmode charging (when you charge it while powered off, instead of showing the charging screen, it will boot into twrp with touchscreen disabled)

- mtp

and more...

I recommend you only to boot it, which you can do by using "fastboot boot twrp-2.8.6.0-a31ul.img". If you persist on flashing it and dont care about the bugs, you can use "fastboot flash recovery twrp-...img" to do so.

You can flash the following zip to install supersu. https://download.chainfire.eu/396/supersu/

Bloody hell you work fast, will try on mine after work. I did have my boot loader unlocked but have since locked it again. If I unlock it again will it wipe my phone again like it did last time.

Are you looking at building a cyogenmod build for the phone? I used to have cyogenmod on my old galaxy s3 which was awesome. It's a shame the budget and mid range phones get forgotten about with modding.

[Android Q&A, Help & Troubleshooting] patrik.KT:
First of all, download the superuser zip from the link in my previous post and put it either on internal or external storage. Then, you must have a computer with adb and fastboot installed. If you do, download that file, open a cmd or terminal window from the directory fastboot is in. Copy the downloaded file into that directory as well. Then connect your phone and enter this command: fastboot boot twrp-2.8.6.0-a31ul.img

Then flash the zip and you have fully rooted your desire 620 :)
[Android Q&A, Help & Troubleshooting] patrik.KT:
Twrp is now fixed and source built. The only bug present is off mode charging - it shows a blank screen instead of the charging image. After that is fixed, you can download it from twrp.me

You have to unlock your bootloader, then boot (not flash) twrp using "fastboot boot twrp-...img". Then in the advanced menu, open terminal, tap select and enter this: dd if=/dev/block/bootdevice/by-name/recovery of=/sdcard/stock-recovery.img

That will backup your stock recovery to the root of internal storage.

The zip file is not an RUU Windows executable.

With that zip file you rename it to

it-file.com doesn't hold RUU files for every region so I downloaded the boot loader zip files.

Not having a HTC before I didn't realise having S on in the boot loader affected what you can do with root.

"S-OFF reduces restrictions on accessing the NAND flash memory on the device, allowing all partitions (including*/system) to be mounted in write mode while the operating system is booted."

Essentially you can't remove unwanted bloatware by you system app uninstallers from the playstore in combination with root.

If*you are*S-ON*and you don't like bloatware you must do it from*RECOVERY*[custom recovery of course]

Boot your device into recovery mode [TWRP]

Click on :*Mount*/ Check the square where it saysSystem*[so mount system]

Click back

Click*Advanced*/ then click*File Manager

Scroll until you see :*system

Click on*system*/ then click*app

Now, from there you delete all the apps you want, including the*odex*files.

After you deleted the apps you want click on*(Up A Level)

Then scroll to*priv-app

From there delete also all the apps you can find and want to delete and you didn't find in*system/app

After you did that click again on*(Up A Level)*and again on*(Up A Level)

There click on*data / app*[click data, and then click app]

There you will find the apps you deleted and their updates, so delete those too.

http://xdaforums.com/htc-one-m8/general/guide-htc-one-m8-how-to-delete-apps-s-t2947154

I used this method on the desire 620 to remove by bloatware from my UK Orange version.

All Amazon apps

Facebook

Twitter

Instagram

Linkdin

HTC scribble (called LUCY.apk)

You need to be carefully what your deleting as you could brick your phone so do some research into what's necessary for your phone, as the bloatware will range from region and carrier.

Another thing I wanted to do was patch the kitkat sd security issue. On Kitkat third party apps can't write to the external sd card.

There's some apps on the play store that will do this.

SDFix: KitKat Writable MicroSD

NextApp, Inc.

SD KitKat Fixer

JRummy Apps Inc.

However if you reset your phone the issues goes back due to S-ON. So what I did was locate with es file manager and the root explorer.

/system/etc/permissions/platform.xml

This is the file which controls the write permissions on the sd card. Once I patched the file I copied it to my external sd card.

Reset the phone and loaded twrp recovery.

Mounted system

Went to advanced and the file manager

/system/etc/permissions/platform.xml

Renamed this to platform-old.xml

And copied the patched platform.xml file from my sd card to the same location.

Now I have third party apps have permant access to write to my external sd card.

And lastly because I used Barclays banking app and sky go, both these don't work on rooted phones. So I tried unrooting the phone through super user, but the phone resets and root remains.

How to unroot phone, you have to delete the su binary file and the superuser.apk file from within twrp file manager. This covers how I did it.
