[Android Q&A, Help & Troubleshooting] BlackenedEDIT:
Just some more information as Sunshine and S-Off were mentioned here a page or so ago. Last night I tried Sunshine to S-Off. Whilst the phone passed the checks and I was able to purchase a licence, this phone is not compatible as it's particular 64 bit architecture is not supported. The good folks at Sunshine troubleshooted with me for quite a while before refunding me the fee. It's a shame we can't S-Off, I did see a kernel module for the desire 610 that disabled system write protection that was flashable in recovery, I didn't attempt as it was for 4.4.2 but if there is a new build coming this is fairly redundant anyway. Just thought I'd share.

Yesterday I tried "cm-12.1-20160121-UNOFFICIAL-a31ul". My initial impressions were really good. Great job Patrik! Unfortunately, I had to return to stock as I could not encrypt the storage and that is mandatory for my Exchange account to work. I know that there are Xposed modules that remove that restriction, but I prefer to encrypt it!

If encryption had worked, I would have tested if TWRP works with CM encryption. With stock encryption, it does not work...

I had the feeling that the battery usage was quite high... Do you think the same?
[Android Q&A, Help & Troubleshooting] BlackenedEDIT:
Just in case anyone missed the announcement TWRP 3.0 is available for our device. https://twrp.me/devices/htca31ul.html

I have it installed and have tested backup, restore and file manager. All working perfectly.

Thanks for the notice. Encryption still does not work with this version, though! [emoji20]
[Android Q&A, Help & Troubleshooting] patrik.KT:
Encryption with stock roms is not going to work, this applies to other htc phones as well. Only CM/AOSP based encryption works and since in cm12.1 encryption doesn't work, we can't test it.
[Android Q&A, Help & Troubleshooting] jamacuco:
That makes a lot of sense! Thanks! If you work on fixing encryption in CM12.1, I will test it!

[Android Q&A, Help & Troubleshooting] patrik.KT:
Good to hear that. I don't really have that much free time, so I don't have time to work on cm. I'm testing out some possible battery fixes and as soon as i find one, I'll rebuild cm and post a new build here.
[Android Q&A, Help & Troubleshooting] jamacuco:
I don't know if the problem is the same, but in my previous phone, CM encryption did not work because the ext4 filesystem created from recovery used all the space in the partition, and to have encryption working, you need to leave a few bytes free to store the encryption key:

http://forum.cyanogenmod.org/topic/116348-cyanogen-121-encryption-setup-does-not-finish/#entry546188

I didn't have time to test this with your build for the a31ul. But I should try it!
[Android Q&A, Help & Troubleshooting] patrik.KT:
With HTC devices, the encryption is a bit different. There's no encryption footer in the data partition, instead they used a separate partition (called extra) to store the encryption key.

[Android Q&A, Help & Troubleshooting] baxter006:
Contacted one-click root, they don't support the 620 and have no plans to. Also opened a ticket with the help desk on ir-file about a custom recover, i've had no reply from the admin guy who sent me that img that didn't work. As a lot of there phones Rom collections have a recovery folder with custom recoveries.

I think its getting to the stage where we are gonna have accept we won't get a recovery. I'm planning to sell this phone April next year anyways as I'll be buying my wife's HTC m8 when she gets her upgrade.

what I didn't realise is only the high end phones seem to get recoveries built

Samsung s1,s2,s3,s4 etc and note series

HTC one series m7,m8,m9

the mid range phones seem to get ignored, I know my old Xperia Ray got root without a custom recovery. You had to down grade and then flash a stock rooted Rom.

from the looks of it the 620 will only ever get kitkat 4.4.4, as it only has 1gb ram its prob not suitable for a stable lollipop release.

---------- Post added at 06:44 AM ---------- Previous post was at 06:39 AM ----------

i unlocked the boot loader pretty much as soon as getting the phone, what i didn't realize at the time was there wasn't a custom recovery build for it. I contacted a admin at www.ir-file.com after getting a subscription to build a recovery. He sent me one back in an email but it doesn't work, and he has't replied back. I've requested one from TWRP website and another guy on XDA who build recoveries, 7alizani is in discussion with someone else to build a recovery. The annoying thing with recoveries is that get made for the high end phones like HTC one/m8/m9, Samsung s3/s4/s5 and note series. But the mid range phones on all brands seem to get ignored, and they need root just as much to get rid of the bloat ware and generally speed the phone up with tweaking apps that all need root.

Where trying to get someone with Linux experience to compile a recovery either TWRP or clockworkmod from the files we have posted. The annoying thing is we have all the files needed to compile a custom recovery but don't have the experience to do it. I've been using windows since windows 3.1 so Linux is completely alien to me.
[Android Q&A, Help & Troubleshooting] baxter006:
Just been on www.ir-file.com under the desire620 they have added a recovery section Which has the recovery.stab file from stock we have extracted from the stock recovery.

http://www.ir-file.com/portal/index.php?dir=Firmware/HTC/HTC_Android/A31_UL/Recovery/

which is labelled exactly how I labelled it. Meaning they must have been on this tread . Still no reply from there admin who sent me the non working recovery.
[Android Q&A, Help & Troubleshooting] 7alizani:
Our problem is, that we do not have a custom recovery. We unlocked the bootloader already. I seek and pray for someone to compile it from source, long time ago. I have a promise from one moderator here on XDA, but that person is too busy, so even there I had no luck. I have no Linux experience, using Windows 20 years. Thats my sad story.

USB Tether not working

Hi guys, I was able to root, install TWRP and install the latest version of Patrick's ROM, I tried to connect my phone to my RT56U router to use the data connection.

I factory reset both the phone and the router, but the little toggle stays grayed out when I try to start tethering. The router recognises the phone as an HTC android phone.

Also, I'm not able to change USB Connection type, it kind of hangs and doesn't recognise the change.

I've had this problem before with a Galaxy S3, and was able to fix it by flashing a custom kernel.

Will Xposed help with this problem, or does anyone have any idea how to fix it.

Is the usb tethering support kernel related?
[Android Q&A, Help & Troubleshooting] Tribal life:
Thanks for the tip, however no luck!

I tried with all versions of TWRP and I get ERROR 7 with them all.

I've re-downloaded Patrik's rom to make sure there where no currupted files.

I then tried manually removing the device singutures to get rid of the error. Still no luck installing a custom rom!

I've rooted the phone and unlocked the bootloader, but I've had problems with busybox. Does this hint to anything? Maybe I'm missing something obvious! ? :confused:

The State of the HTC Desire 620 (a31ul)

Hey guys,

so for the past week, I have been trying to build LineageOS for A31UL even if there are bugs. This phone is compatible with the latest Version of android which is Android 7.1.2_r2 as the WIleyfox Swift 2 has the same SOC and runs just fine. I will try to get in contact with [MENTION=4814653]patrik.KT[/MENTION] and see if he can guide me in building LineageOS.

How to install HTC Desire 620 System

I was a little confused as to how to do this. Any zip file from firmware.gem-flash.com isn't corrupted i'm pretty sure. But you cannot open the 0PE6IMG.zip on your computer. Don't try to install System using the RUU as you need to download Microsoft Visual C++ Redistributable 2008 (x86) and even then I haven't had success on Windows 10

Step 1: Download any zip you want. (The website only allows max 3GB worth of downloads), PM me if you need another zip.

Step 2: Lock your bootloader (connect your HTC to your phone and run fastboot oem lock)

Step 3: Format Micro SD Card and then copy 0PE6IMG to SD Card and rename it to 0PE6IMG.zip

Step 4: Boot into HBoot / Bootloader, within 5 seconds of you booting, it should AUTOMATICALLY open 0PE6IMG.zip and then install it (This step will take a long time and no MATTER WHAT YOU DO, just leave it. Give it 1hr and 30 mins to complete the process (it should only take 30 mins) and it should tell you to press the power button to reboot or something similar.)

Step 4a: if it says FAILED TO VERIFY UPDATE FILE (or similar) MAKE SURE YOUR BOOTLOADER IS LOCKED, IN HBOOT IT SHOULD SAY **RELOCKED** (if you unlocked it before)

IT does not matter if it says **Software Modified**

Step 5: Boot into Stock HTC Sense Android xD

Fixed my primary phone, going to start with the HTC Desire 620
[Android Q&A, Help & Troubleshooting] liammendes:
The latest from patrik was cm12.1 and it was pretty stable, it was GOOD not EXECELLENT, the OS was sometimes sloppy and sometimes we had a crash hear or there or a bug such as you couldn't see the In-Call UI to end a call and although there was a attempt to release cm13, that never happened so there are only cm12.1 builds for our device, I tried yesterday to make LineageOS 14.1 and it compiled but I can't get it to basically boot. Our kernel is way behind everyone else and therefore out of date. I am trying to compile LineageOS 13 now and if that dosen't work Ill think of something else, maybe getting cm12.1 to fully stable before porting to 13 then 14 then hopefully by LineageOS 15 and Android 8.0 we have more people on this helping us port it. I wont release the LineageOS 14.1 because it boots straight to Fastboot so there is no point. Neither does the compiled recovery work.

I invite many of you guys to work on this with me and even invite some Device Maintainers help me do this because I do not think I could do this on my own.

That's just a little sneak peak into what's going on, as for the active development for our device, Is it Dead? I don't know we will have to find out :D
