i did step 1-4... but i haven´t restored the drm keys/ta partition.

I don´t know if there are any lags using the ps4 remote play app.

but i think it is a very smooth and fast rom so i would give it a try. ;)

That's great thanks for your help
[Xperia Z3 Tablet Compact Original Android Developm] Fr3lncr:
Hello,

I was looking for some help/direction. I have a Rogers (Canada) version of the SGP 621 which has a locked bootloader. I've read through all of this thread and the previous version but I don't believe I have read of anyone having success installing LineageOS with a locked bootloader? I did find a thread where someone was successful in rooting their Rogers SGP 621 (XDA Thread Link), but that's it.

I was really hoping I could get this working on my SGP 621 as it would delay getting another tablet so I was just wondering if any one who has the Rogers version has had success with this or if it is just a lost cause?

Thanks in advance. Cheers.
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
Working well and seems pretty stable. Thanks!
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
With a locked bootloader you can't flash alternative ROMs, you might be able to root but that's about it. Worth trying the Sony Dev site just in case.

---------- Post added at 11:56 PM ---------- Previous post was at 11:54 PM ----------

Just a ping to see if the thread is still going and if there's plans for official builds or are we stuck until Sony release Nougat code?
[Xperia Z3 Tablet Compact Original Android Developm] Fr3lncr:
Thanks. I did check the Sony Dev site but there is nothing for the Rogers variant and I already came across a thread on a Rogers board where they were unsuccessful in getting Rogers to unlock the bootloader.

Oh well... Guess I'll give this to the missus and get something newer for myself.

Battery

I installed the rom yesterday. Most ist really stable and smooth. But battery life is horrible.

I attached a screenshoot, is this normal?

I have a Z3 phone (almost the same hardware) an this ist not active while Screen is off. I deactivated NFC and installed Naptime, but it doesent help. Any idea?

I did clean install + gapps pico.
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
The latest version has a Bug, that enables keeps nfc enabled and hogging the system. Please look a few pages back and in comment #93 where there is a zip file that includes the files to fix this. This also will be fixed in the next iteration of the ROM which should arrive in a few days. But I am still fighting with some things sony and lineage changed.
[Xperia Z3 Tablet Compact Original Android Developm] SageDroid:
Thank you for your quick response.

I did it, will report if it works.

Keep up ur good work! :)
[Xperia Z3 Tablet Compact Original Android Developm] torben5247:
I use L speed. for optimizing my battery consumption.

If i turn off wifi when screen is off my tablet are using 0,2% pr. hour. If wifi is on it is 0,5% pr. hour.

I think it is the same as stock.....

I'm an android newb can anyone say how I bring up the app draw in landscape mode please?

Portrait works fine.

I'm prob just being an idiot so any help would be appreciated!
[Xperia Z3 Tablet Compact Original Android Developm] SageDroid:
Thanks! Will try it and report.

With NFC Fix i have now 0,5% /h in fly mode. But there is still something with nfc wrong. Logcat is full with nfc entries. Will have a look later on it.

Edit: With L Speed 0,35% in fly mode, do u use aggressive doze?
[Xperia Z3 Tablet Compact Original Android Developm] torben5247:
i am using L speed 1.4.13 beta 6. i am using agressive doze and all the other battery saving features.

I am also using greenify, but that doesn't make that much difference i am only using it for the icon on the screen to turn off screen and shut down Facebook. ;)

[Xperia Z3 Tablet Compact Original Android Developm] Sjd08:
Thank you for your work on this! First attempt at replacing CM with lineageos for scorpion_windy... Couldn't get v6 to install, the setup wizard crashed every time. So tried v5 with nano gapps... Installed but constant android.process.acore nag error. Tried all the usual cache contacts clearing and such, no use. So eventually installed v5 with pico gapps and all works well, very happy. Hope someone finds this useful or am I alone with this problem?!?
[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
It's a problem of v6 itself, you have to flash only the rom, reboot and then do a dirty flash of the gapps, and everything will work.
[Xperia Z3 Tablet Compact Original Android Developm] fryguy7:

Im wondering if its possible​ to get better camera quality with custom roms by restoring drm keys somehow?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Good news everyone! All kinks should be worked out now and it built and ran fine for a few days now. That means, that v7 should be ready later today.
[Xperia Z3 Tablet Compact Original Android Developm] iamnotkurtcobain:
So all remaining bugs fixed?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Nope, sadly not by a Longshot :) But no more bugs introduced (hopefully) and newest binaries and patches integrated, which broke a lot of stuff. Battery consumption should now be even better while getting better performance as well (at least from what I measured over the last few days).
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
V7 is available now. Lots of changes under the hood. Should have better battery life and a little more performance. If you encounter any NEW bugs, please post them. I will try to fix those along with the known ones ASAP.

Changelog:

06.06.2017 - V7:

- Integrated new RQBalance-PowerHAL and librqbalance from Sony's GIT

- Newest Lineage, Sony and Android Sources

- Android May security patches

- Small fixes everywhere

I didnt have time yet to install v6, can I upgrade directly from v5 to v7 or better install v6 between?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Directly upgrading from v5 (or any earlier version for that matter) should not be a problem.
[Xperia Z3 Tablet Compact Original Android Developm] jacktheriefla:

I cannot connect to my 5ghz WiFi anymore in v7. worked perfectly in v6. what logs do you need? thanks:good:
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Strange, seems to work for me here. Drop me a logcat from bootup. Then disable and enable wifi, wait until wifi is back and send me the log. The drivers and firmware have been updated for v7, so I will have a look there.

Also please post the output of

adb shell dmesg

Update: Tried with three different 5Ghz only APs here and all worked. So I may need more specific logs.
[Xperia Z3 Tablet Compact Original Android Developm] b8drf:
Thanks lowtraxx for your continued support for our great little Tab...

Smooth (dirty) install from v6. The first thing I always check is in call volume control which is a big deal for me, still think the same problem as earlier releases - is this something I will need to live with or do you think there is some hope of a fix?

Keep up the good work! Cheers. :svetius:
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Volume control issues (in and out of call) are still my top most priority, but sound problems on Android are really really hard to find and debug :)
[Xperia Z3 Tablet Compact Original Android Developm] finalista:

as always very good release:svetius:

5ghz WiFi signals missing!

Firstly thank you lowtraxx for all your hard work, love the rom, very much appreciated.

Upgraded Scorpian_windy from v5 to v7 and 5ghz WiFi not working. So set a country code (Europe) within advanced setting, then restarted WiFi and all is well and working happily again!

Thanks.
[Xperia Z3 Tablet Compact Original Android Developm] b8drf:
I am not experiencing volume issues in general, the only one I have is in-call volume via the built-in speaker - if I make a call via a bluetooth headset, then the volume control works fine - weird :confused:

NFC not working?

V7 scorpion_windy, NFC toggle button doesn't switch NFC on, is it supposed to work? It just flips to grey? Thanks.
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
Great job! Is this close to getting "official" builds at this point? Sorry if that's a rude question.

Thanks :)
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
NFC should work. Just tried it again. Flips on and off as designed. Could you drop me a logcat so I can investigate? Could other windy users try as well please.
[Xperia Z3 Tablet Compact Original Android Developm] wulfiss:
I have a windy and I can say that the NFC turns on at least the button turns white and the switch seems to turn on normally. I don't know if the NFC works because I don't have another device with NFC.
[Xperia Z3 Tablet Compact Original Android Developm] KuLakow:
Caught old bug: auto-volume. When set volume low, it become loud. When set on middle or higher, volume become quiter. Restored backup on V6, now It's 'ok' (loudest on the middle).
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
Anyone using the WiFi setting for "enabled during sleep” -> "only when plugged in"?

For me this setting leaves WiFi disabled when waking the tablet (unlocking), and I need to manually enable WiFi each time. Occurs on V6 and v7.

Sent you the logcat for this, was that enough detail? Also did a complete factory reset and flash of v7 to see if this fixed it, but no use error persists, NFC will not enable. Others suggest NFC works, so is it more likely my tab is broke?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Yes, I had a look at it. From the looks of it the tablet is not able to enable the NFC hardware.

Which was the last official Sony Firmware you had on the tab before flashing Lineage? Did it work on v5?
[Xperia Z3 Tablet Compact Original Android Developm] CrazyPeter:
5Ghz wifi doesn't seem to be working in V7. Anyone else confirm?
[Xperia Z3 Tablet Compact Original Android Developm] phillamg:
Works for me, but I had to toggle wifi / reboot (can't remember). Then I went into my saved networks and it connected to my 5GHz one.

Wifi doesn't seem to come back on when the device wakes from sleep (with wifi set to never stay awake). I'm still testing it - can anyone else confirm if this is a known issue?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
See a few posts back. You need to enable your region/country in the WiFi advanced settings. Otherwise it will not connect.
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
Is that related to my issue of no WiFi reconnection when setting "WiFi on during sleep” to "only when charging"

I get that too. Trying with the country code set at present.
[Xperia Z3 Tablet Compact Original Android Developm] milox_x:
So first of all im very thankful for this rom and your work [MENTION=615507]lowtraxx[/MENTION] . I was using AICP for 2 Months and i've discovered that after switching to LOS v7 that performance on Clash of Clans dropped down, by this i mean that it is running slower than on AICP. Can I maybe do something for this to run better?
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
I don't know which CPU governor AICP uses by default. This version of LOS is more fine tuned for battery usage. You could try to change the governor to something more game friendly with kernel adiutor for example.
[Xperia Z3 Tablet Compact Original Android Developm] milox_x:
Changed CPU Gov to performance and I/O Scheduler to zen and it is a lot better. Even better than AICP now. Thanks.
[Xperia Z3 Tablet Compact Original Android Developm] CrazyPeter:
Yep, perfect, thanks. Now working correctly.

No issues, but a couple of questions, fast charge, will it ever be in this ROM? (is this a kernel thing or a OS function?)? I understand the reasons, bit I really miss it.

Secondly, I always have trouble getting ROM working in conjunction with TWRP. To use recovery, I jsve to put the tablet into fastboot, flash TWRP, which only boots TWRP, and to get the main OS ruining, flash the boot.IMG from your zip.

Is there a better way??? Or is this it?
[Xperia Z3 Tablet Compact Original Android Developm] belrik:
Still seeing WiFi reconnection issues coming out of suspend unless WiFi is set to "always on” any ideas? Using correct country code now.

Just trying to eek out a few more days battery life when I leave it lying round the house and forget about it...
[Xperia Z3 Tablet Compact Original Android Developm] Sjd08:
ERM haven't been on stock for a couple of years, so I'm guessing it was probably 5.1.1 or something?!? Also as you may of guessed NFC didn't work for v5 either. Are you thinking I need to flash the last stock ROM to get it back up to date, then reflash v7? Thanks in advance for your help!
[Xperia Z3 Tablet Compact Original Android Developm] lowtraxx:
Yeah, that was exactly what I was thinking. You see, once you flash a stock firmware you get the "Updating NFC firmware" dialog. I guess maybe the "firmware" that gets updated there is no longer compatible to the newer blobs that we use in lineage. But that is just a guess. Maybe your NFC really is broken. Give it a try and report back :)
[Xperia Z3 Tablet Compact Original Android Developm] ccgx:
Got problems with updating from v5 to v7. Had to reflash v7 and reflash gapps. But since I had some problems with updating some time ago, I'm pretty sure something is borked and I should reset my device and start from scratch.
[Xperia Z3 Tablet Compact Original Android Developm] Sjd08:
So recovered to stock 6.0.1 after a bit of head scratching!!! Why is Emma only Windows? I have no windows machine so that was fun! Mono with Flashtool/XperiFerm saved the day! When flashing I noticed updating NFC firmware pop up. When finished I went into the Sony service test area and tested NFC as working correctly.

Then reflashed LOS v.7

NFC tested and now works but...

Ive noticed the NFC toggle switch can start irrationally flicking between on and off, if I try and logcat this via a USB cable the NFC toggle stays on and scans without issue, so I cannot get an error log?!? Very strange! If I then remove the USB cable the switch will undoubtedly start flicking again causing NFC scanning issues! Hope this makes sense!

If I just toggle NFC off it stays off without any flicking!

And thanks for the help! :good:

Out of interest... because its been a while since flashing stock back on the Sony I couldn't quite remember the correct way of flashing twrp. In the end I did "fastboot flash boot twrp.img" which allowed me to load on LOS. Then I thought about it and realised I probably shouldnt flash twrp to boot, but it seems to have worked and I have no issues. Is this correct? :confused:

Camera images of near distance shots very blurred

Dear Lowtraxx, many thanks again for your amazing work.

Sometimes I'd like to take photos of some text on a monitor, i.e. document some BIOS errors, etc. When I take such shots with SGP621's camera (distance to monitor roughly 30-50 cm, 22" monitor) I can not read any of the text on the monitor since the image is very blurred, the photo seems entirely out of focus and touching some parts of the live image of the camera to set the focus does not help. First I thought that my camera may be broken (some time ago my tablet fell to the floor, but no visible defects). But now - for a test - I installed the latest Sony firmware (SGP621_23.5.A.1.291_1290-4945_R3D - without DRM keys). With that firmware I can read without any problem even text written with a 6pt font in images taken with the camera. The image is sharp and with all details. When I switch back to lineage-14.1-20170605-UNOFFICIAL-Lowtraxx-scorpion I can hardly read text written with an 18pt font, one can only guess. All blurry. The usual font sizes (12pt, 10,pt, 8pt) are impossible to read at all.

I know that some other comments reported some camera problems too. But I was not aware that the problem is that drastic for near distance shots. Larger distance photos like a room or landscape are not so much a problem since that seems to be the default focus of the tablet's camera.

It would be great if you could fix that problem some time. I appreciate very much the time you devote to the ROM and to helping us.
