Ahah yes ! :)

Since one or two weeks I'm searching a way to root this phone and to upgrade it to Lollipop or Marshmallow, then I found this topic, it's like an Eldorado for my 620. :p

Patrick does so much work for 620 users, it's amazing.
[Android Q&A, Help & Troubleshooting] baxter006:
Glad l you got it working, I find the whole adb thing very fiddly. Flashed my nexus player recently took me two hours to get the boot loader unlocked.
[Android Q&A, Help & Troubleshooting] Kainey:
Thank you, yea it's hard when English is not your native langage and you don't know everything on Android. I haven't flash a smartphone since 2012 lol.

Well I've tested CM12 on the 620 during 3 hours and I noticed some issues :

-Sometime the phone is ultra smooth, and sometime it becomes more laggy, maybe just a little optimisation problem.

-3D games are freezing (Fallout Shelter is unplayable) when 2D games are more smooth (Drive Ahead ! for exemple) than with original ROM.

-I have LTE instead of 4G, and a strange "!" in network indicator, I must confirm an error before data be avable.

-Wifi takes more time to be enabled than stock ROM

Hope it can help.

EDIT :

Oh, and, I'm back on stock ROM, it's rooted but when I remove an application with Titanium back up it returns in my phone after a reboot. Do you know how to definitely remove a system app ?
[Android Q&A, Help & Troubleshooting] BlackenedEDIT:
I believe you need to make /system writeable by setting the S-Off flag. There are several tools to do this, although I can only find them for older HTC phones. There are several commercial services that claim to do this for a fee, but I would wait for someone more knowledgeable than me to offer another opinion first.

hello so is there a fully custom recovery working for this device please,,????
[Android Q&A, Help & Troubleshooting] baxter006:
There's a script you have to run in terminal wp_mod.ko, it's mentioned earliar in this thread. This allows you to remove system ups etc, but who have to run it each time you reset the phone.

---------- Post added at 09:19 AM ---------- Previous post was at 09:17 AM ----------

Yes patrik has built a TWRP recovery and cyogenmod 12.1 for this HTC.
[Android Q&A, Help & Troubleshooting] bygrave:
do u have links please cant seem to find them,,thanks
[Android Q&A, Help & Troubleshooting] baxter006:
I have the files on Google drive

https://drive.google.com/file/d/0Bw7S-kfd-L-RQ3FEODhvLTh3RzA/view?usp=docslist_api

Put this wp_mod.ko file on the phone not in a folder just the root of the phone.

Then install a terminal app from the play store

Open the terminal app

Type "su" then enter, terminal will ask for root permission so allow

Then type "insmod /sd card/wp_mod.ko"

Not you can use titanium backup to remove system apps etc.

You won't actually have s-off, so you need to so the terminal thing every time you reboot.

I take it you didn't like the performance of cm12.1 I've not gone back to stock since patriks third build of cm12.1 ( one from end of November)

[Android Q&A, Help & Troubleshooting] baxter006:
Sunshine is $25 right? No one on this forum has mentioned they have done it.

I'm personally not that worried about it, I've gained space through link2sd converting user apps to system and moving large obb files from games to the extenal SD card.

[Android Q&A, Help & Troubleshooting] MadChuck:
The new build is so much better and stable, but there is one huge issue. It's about dotcase app, because every time you get called or call someone, the dotcase displays contact details and it doesn't disappears till the phone restart. It wouldn't be a big deal, but it keeps the screen on, even when in the pocket. In effect the battery die really fast :(
[Android Q&A, Help & Troubleshooting] patrik.KT:
https://drive.google.com/file/d/0B5KRmU8P96dlZFJrSmw0ZWZTNXc/view?usp=docslist_api

Copy this to /system/app/Dotcase/ and reboot. It should be okay with this. I forgot to cleanup the dotcase app before uploading this ROM.
[Android Q&A, Help & Troubleshooting] baxter006:
Should tap and pay work in settings, my bank has just added NFC payments. To use Barclay's apps I have to unroot, but when I go to turn tap and pay on settings crashes.

"Unfortunately settings has stopped"

Gonna restore stock back tonight and see what's sposed happen in settings with tap and pay. Chrome has been really sluggish on cm12.1 recently.
[Android Q&A, Help & Troubleshooting] MadChuck:
Thanks, Patrik, dotcase works properly now :)
[Android Q&A, Help & Troubleshooting] patrik.KT:
To every user of my cm rom: are you sure the battery life is okay? Can you send me some screens of the battery usage page in settings? Did you install any extra packages on tip of the cm zip?

The only reason I'm asking this is because I'm still experiencing high batters drain and I'm not sure if it's caused by the rom/kernel or my battery is just slowly dying.
[Android Q&A, Help & Troubleshooting] baxter006:
Yeah ive had no problems with battery life, i'm just doing a recovery to stock to see if the Barclays NFC payment works on stock normally. I have never installed extra packages at all, and my phone is always on 2G only as i don't get very good phone signal at work, i imagine 2G users less battery. Wifi is on but only as i need it, and i changed it to turn off when the phone is in sleep mode. Will send you a screen capture of the battery usage later tonight.
[Android Q&A, Help & Troubleshooting] baxter006:
Been on stock again for a day, forgot the smoothness of stock. Cm12.1 I know chrome would sometimes be rather laggy. I'd been on cm12.1 since December last year, the other issue i had was you tube kept bringin up a retry error before it would play every video. I actually thought it was an issue with my wifi at home, but turns out it wasn't.

Gonna stay on stock until patrik has released another update, as its a bit of hassle for me to swop. Each time I have to ring my bank to reset my registration on the app. I do miss the notification system of lollipop though.
[Android Q&A, Help & Troubleshooting] patrik.KT:
Did you have the youtube retry error in stock? Because I did. If you did not, could you upload your system dump of the stock rom?
[Android Q&A, Help & Troubleshooting] baxter006:
No first timer I had the error was using your 4th version of cm12.1. I'll upload the system dump later this afternoon, did you get a chance to look at the pay and tap in settings. .

Going back to stock I've noticed the battery had faired better. I'm at work and the wifi has been on all day and I'm on 80%, I'v had a 30 minute phone call as well.
[Android Q&A, Help & Troubleshooting] patrik.KT:
I haven't check the tap and pay yet. I didn't have any chance to fully test nfc, as this is my only nfc phone. Also tags and cards will most likely not work, because HCE is disabled in CM.
[Android Q&A, Help & Troubleshooting] baxter006:
Didn't know CM hasn't got HCE, its not a massive issue. But tap and pay is becoming more common here in the UK, so maybe its something Cyogenmod team need to look at for the future of development. I'm currently uploading my system dump to google drive now.
[Android Q&A, Help & Troubleshooting] patrik.KT:
It's only disabled in my builds, I'll try to enable it in the next builds. The settings FC is caused because of the disabled HCE:

EDIT: So I enabled HCE and settings don't FC when going into Tap & pay (proof). I'll upload a new build in a few minutes.

[Android Q&A, Help & Troubleshooting] baxter006:
Great work will probably test over the weekend, are there any optimization or battery improvements?
[Android Q&A, Help & Troubleshooting] patrik.KT:
I fixed the voip speakerphone bug, but no optimizations from my side, only mainstream cm updates. I'm rebasing our kernel to the latest caf tag with 64bit support in my free time, so if I get that working, it should have some optimizations from qcom.

[Android Q&A, Help & Troubleshooting] baxter006:
You know how to get to booloader screen? Upload a picture of your booloader. You'll need to take a pic with a camera. RUU is a exe file thay will let you flash the htc back to stock using windows.

very nice rom unfortunately im having issues phones works perfectly for 5 min the almost stalls and wont do anything until i take the battery out and boot it bk up not sure if im the only one or not ill try to re flash the rom and keep my fingers crossed its just a one in a million thing ill let u know how i get on
[Android Q&A, Help & Troubleshooting] baxter006:
I started to get the same issue last couple of weeks, not something I really had when I first flashed cm12.1 mid December. Kept with it till early this week, but wanted to test NFC with my banking app so went back to recovery image of stock. Which is giving me better battery life and less chugging as your getting. I guess it's just optimization for the Qualcomm cpu via the kernel maybe.
[Android Q&A, Help & Troubleshooting] sidewindersnake:
yea sounds like the same thing not bad tho for how quickly this has moved along be nice to see option like on the htc sensation kernel that let u choose to over or under clock you cpu to just saves one more thing ill have to download and a swapfile between the ram and sd card to help the ram along a bit as it is lacking another month or so and i think this will be a very viable rom to use looking forward to it gunna flash mine bk to stock now for the time being

Hi baxter006

Would you mind sharing the link to the Europe RUU in your Google Drive? I saw the link to the UK Orange version, but not to the Europe one!

Thanks for the amazing work that you and patrik are doing to get the most of this phone ;)
[Android Q&A, Help & Troubleshooting] BlackenedEDIT:
I've just done a full wipe, including the system partition. Removed the gapps package I was using and flashed the new build yesterday. After picking a choosing the gapps I wanted and re setting up the phone, this build already feels more stable.

I was having fc problems in the last build with the cm browser so have gone with chrome and removed cm browser. Battery seems good, about 75% of stock I'd say and I've not had any of the stuttering or stalling I was getting with prior build but only time will tell.

I'm a very grateful user of the build patrik and if I can be of any help please just ask.

Its not a RUU file, you need to rename it to 0PE6IMG.zip and place it in the root of an external sd card. Then in booloader it should ask you if you wanna flash.
[Android Q&A, Help & Troubleshooting] jamacuco:
Thanks! But I believe that is the pre-OTA version... I already got that one from you at the very beginning of this thread! Unfortunately that version is useless after the OTA... I would like to get the post-OTA Europe version without having to get a susbscription for ir-files, if possible [emoji6]

Or... Anyone can share a TWRP backup of the stock Europe /system without any change??
[Android Q&A, Help & Troubleshooting] MadChuck:
I must share my experiences with using the latest build, because there where some issues since last week. Don't know why, but CM has been too laggy for some days. After updating I was thinking it had been much more stable. Till now. On a previous release I was able to play GTA SA (on low, but still playable), but now it ain't possible no more. I can't even use Snapchat (Ok, I'm using Snapprefs, so it may cause some bad performance) and am no more able to send any picture using this app, which was also hard, but still possible, on a previous build. I often get messages that apps are not responding.

I think it isn't caused by the count of apps on my phone, because I use Greenify and keeps as many apps greenified as possible (except for Messenger, Facebook Lite, Swiftkey and ofc Google Play Services, which I can't greenify) to get high performance. I've also freezed some apps I hadn't been using (FX and some other stock apps).

Also Dotcase app is not working properly again. Have put dotcase.apk in indicated folder many times. It worked only for a first time, don't know why.

I hope another release will fix the laggy problem, but for now I hesitate to get back to stock rom.

-Wifi takes more time to be enabled, and also photo are

-Sometime the phone is ultra smooth, and sometime it becomes more laggy

-3D games are freezing (Fallout Shelter is almost unplayable and Hearsthone simply freeze my phone), but 2D games are fluid.

The ota update patched a vulnerability, I actually flashed an RUU then updated, then rooted again. Some people looking at going from patriks cm12.1 back to stock would need to either use a twrp backup or flash stock roms from ir-file.com.

I kept a backup of stock using twrp, used patrik cm12 for a month , then this month went back to stock. It seems some people didn't use twrp to make a backup before flashing cm12, which is a bit silly. Especially if you don't like the build or ever wanna sell the phone.
