@simon27gr,

This is not a RR Rom issue. Not on mine anyway, nor have i seen any reports of a continued sound issue for this Rom. I use this Rom as my DD and have no issues what so ever.

Have you installed any sound mods? Did you do a clean install. Did you format the data partion in TWRP. To format you would have to type yes?

If you installed a sound mod dirty flash the Rom and see if corrected. If no sound mod(s) installed try a clean install after a nandroid, format data then wipe cache, system dalvik cache. Remember to format data you have to type YES. After format and wipe reboot to recovery and then flash. Not always necessary to reboot to recovery, but sometimes the data partition will not mount after a format until a reboot.

Use TiBU to backup all apps and data. But before you install your TiBU see if the clean flash fixed the problem. Trial and error fixing.

Hope this helps.

have some problem

the network is much slower than the Sony's system , also the quick charge is not work~~am i the only one? and how to slove these ? sorry ,i'm chinese and my english is not good~
[Xperia Z2 Tablet Android Development] _Sherrif:
What do you mean by "the network is much slower"? Are you talking about transfer speeds, connection times, or other. Of course transfer speed depends on the network connected too.

I have never had true QUICK CHARGE on my castor_windy. I know it is supposedly in the hardware, but from what i have read about it, it takes a custom kernel which activates the QC. I have only found this available on the Z2 phone (SIRUS) forums. I do not get true QC when charging but Ampere shows i am charging at 1040mA https://xdaforums.com/showpost.php?p=74330259&postcount=190 . If you are not at least getting 1000ma, check your cable and charger. They may be bad and do go bad.
[Xperia Z2 Tablet Android Development] 球球l笑一个:
Thank you! I use the original cable and the QC goes well. "the network is nuch slower" I said is talking about the transfer speeds, now only 200-800KB, before is 1MB-3MB. Maybe my school's network is not good now, when I go home, I will test it again.~~Thank you for reply.

Hi Guys - I need some help if that's ok.. love RR and keen to get it stable

Hi - I've the same problem described previously (idle reboots). I got a new Z2 Tablet, dowgraded from 4.4.4 to 4.4.2 then rooted, backed up the TA, then flashed TWRP 3.1.0 castor_windy then flashed RR.

Whilst I don't have the exact same ftf file above; I've tried flashing a number of ROMs including the closest I could find.. SGP512_23.5.A.1.291_R3D_Australia Generic_1282-3578.ftf

Everytime I flash via the latest Flashtool; I get an error..

ERROR - null

ERROR - Error flashing. Aborted

I know this has been mentioned in other threads, the solutions (try different ftf - tried about 4 versions, lock bootloader first - ?? if the lock procedure is flash stock, then restore TA - I'm stuffed) don't seem to work for me.

Can anyone help out a newbie (on Xperia's).. Love the tablet; just can't work out the flashing twerks..

Appreciate any advice.

Cheers

Dont use the latest Flashtool Version. It always fails with our device. Not able to check the working Version no. right now, but it was one from 2 years ago orso...
[Xperia Z2 Tablet Android Development] erosco:
Thanks - managed to get 0.9.15 to work.. mind you it had no concept of the Z2 Tablet - but it worked enough for a flash..

Thanks so much for your help.. now to try and get TWRP running again. :)

Have got TWRP installed and up and running? Let us know if you need anymore help.
[Xperia Z2 Tablet Android Development] glowaaa:
The ROM is fantastic, everything works perfectly.

However, I found one bug related to VPN.

The connection is established correctly and works, but when the connection is disconnected (manually or due to lack of network) the tablet will restart every time.

The problem occurs on many custom ROM's with android 7.1.2

Please, solve the problem ASAP.
[Xperia Z2 Tablet Android Development] erosco:
All good now thanks. Couldn't work out how to get twrp running with stock.. but it's fine with RR. I think the stock boot.img doesn't allow booting into recovery. Now back on RR with twrp and all is fine.

Also found a stock that can be flashed from twrp so can go back to it if need. ?

Thanks again for everyone's help. Still keen to know the right/best version of flashtool to use.. but not a biggie now.

Cheers

[Xperia Z2 Tablet Android Development] _Sherrif:
To run TWRP with stock you need to have Dual Recovery installed, https://xdaforums.com/showthread.php?t=2261606 by NUT. Here is the link.

I have always used Flashtool 0.9.19.8 I think there is a newer version or there was but this is the version i have always had the best luck with. If you need a copy of this Flashtool let me know and i will give you the link.

Anyway glad you got working, but if you want to go back to stock use NUT's recovery. You can flash a custom ROM with NUT's recovery, then you will need to flash the recovery you are using now, i assume from rcstar6696, to have a working TWRP on whatever custom Rom you choose. FYI-NUT's recovery is made specifically for Xperia stock devices and will not work with any custom roms. PM me if you have any other questions about NUT's recovery so we do not get to far OT in this thread.
[Xperia Z2 Tablet Android Development] glowaaa:
Bug is related to VPN wich is native build in the android, not a 3rd party apps like OpenVPN.

I havent option to OpenVPN at my provider.

I tried PPTP, L2TP, IPSec and every time reboot occurs.
[Xperia Z2 Tablet Android Development] SkOrPn:
Hey guys, I am trying to find a RR or LOS 10" tablet and have narrowed it down to either Nexus 9 (slightly too small and no sdcard slot), or this Xperia Z2 which has the right size screen.

What I want is stable Ressurection Remix or stable LOS, one that has TWRP support, will get Oreo and stay updated, and will be great for reading articles and keeping my Google Home updated. Nexus 9 looks like it has better support, but not the better hardware. However, Xperia looks slightly more expensive, especially if I want it new.

What I am trading it for. I have a prestine condition Galaxy TAB S 8.4, and it runs RR perfectly and has great TWRP 3.2.1 support. However, the screen is too small for my eyes and I don't trust this Exynox5420 device to keep getting Android updates. My AMOLED screen is perfect, and the device looks brand new thanks to always on case and sp. But being only 8.4" I think I can only get about $130's on ebay. Xperia Z2 10.1" is about $200 now?

Would you guys say this device works great in 2017 and maybe will work great in 2018 on Oreo? Or should I go with Nexus 9, or stick to my pristine Galaxy TAB S 8.4"? I really like the idea of getting a Snapdragon device too because I interpret this as a better change for future updates. I see some people complaining about Nexus 9 in their LOS threads saying things like "This is the worst device I have ever had" etc. lol, I wonder if anyone feels the same about the Xperia Z2 10.1 Tablets?

Do you guys love your Xperia Z2 still?
[Xperia Z2 Tablet Android Development] solved:
Besides that, u can't use the IR anymore and that Games will .. well .. not working great, everything else is perfect on it. Even that we now have an Oreo 8.1 build for this tablet.
[Xperia Z2 Tablet Android Development] SkOrPn:
So as far as you can tell ONLY IR and Games are bad on this device when using RR? I rarely play games, but when waiting at the doctors office I like to open Solitaire on the device. But mostly I want the device for reading articles from within Chrome, and I need a working Gmail, Google Home app, so flawless Gapps is a must. Still surprised that this device is $200 though. These 3 year old devices shouldn't fetch more than $100 imo. Oh well.
[Xperia Z2 Tablet Android Development] solved:
with Games, i meant something like Lineage II. Small Games like Card Games (Solitaire, Bubble Crasher) or simple games (Hearthstone) are working. Gapps and such stuff never had a problem with that, reading manga through Crunchyroll App, watching Streams through Netflix or LiveTV, browsing the internet via Chrome / Canary or Samsung Browser. Even Camera and Facecam Chats working (with proper light) almost perfect. My Tablet replaced my laptop a long time ago .. with all of my email communication, chats and social media stuff. When I'm at home I have my Sony soundbar via bt connected and listen to Spotify.
[Xperia Z2 Tablet Android Development] PVL_93_RU:
I think whatever crashes or perfomance issues one may experience with the games might be poor optimization for Nougat (and Oreo in the future). I had several games crawl to hilariously low FPS counters on Carbon ROM and had crashes with various titles on both RR and Carbon, especially with older games that haven't seen updates in a long time
[Xperia Z2 Tablet Android Development] warthog9:
I might be blind, and not finding the setting, but i've got the tablet locked to portrait mode, however the lock screen only seems to handle auto / landscape. Is there a way to get the lock screen to respect the system rotation, and/or lock it to portrait sans a 3rd party service app?

[Xperia Z2 Tablet Android Development] luispauloben:
I need help. I installed rom but I did not install the gapps and the device rebooted directly into the system. I can not access recovery anymore. the light that was true when the device started, is now purple and the light that was once purple when you pressed the volume down button is now yellow. I already installed recovery via adb and using the towelroot method, I still can not access recovery. someone help me please. also tried installing a new firmware with the flash and could not.
[Xperia Z2 Tablet Android Development] _Sherrif:
[MENTION=8534758]luispauloben[/MENTION],

Not sure about the towelroot method, never used it. I would try this first.

Use 7zip to view the zip archive of the RR rom you downloaded and want to install. While viewing the archive right click the boot.img and copy to the same folder you downloaded your rom to, easiest to find it there. Download TWRP recovery from here https://drive.google.com/drive/folders/0BwBZlgiV0lNiQmo1c1VHakVJcUE use 3.1. This TWRP recovery is from rcstar6696 download section for castor_windy. IF YOU HAVE A CASTOR GET THE CASTOR RECOVERY FROM THE CARBON ROM SITE. I always take anything i want to flash or install and place them in the abd-platform tools folder, then open the cmd prompt in the folder and do the below.

Turn off the tablet. Then press and hold the vol up button and connect to your pc. You should get a blue light, you'll be in bootloader mode. Then fastboot flash boot boot.img, then fastboot flash recovery recovery.img, or whatever the name of the recovery is. Then fastboot reboot and press the vol up to get back into recovery and reflash your rom.

If the above doesn't work, not sure. You may have to flashtool an FTF and start over

[Xperia Z2 Tablet Android Development] solved:
GPS working for me without any Issues (Germany) for the SuperSU Problems .. stop using SuperSU .. oO use Magisk instead. You are using a Tablet with a different Boot Image and unless you are using the old boot image inject for supersu it won't work. You have to change the boot image on the z2 tablet in order to use root and that's exactly what magisk does.

Any tips for tweaking the CPU frequencies or improving deep sleep situation? I noticed the device charges really slowly on this ROM compared to stock firmware.

I could go from 0 to 100% in about 4 hours on stock, but here it seems to take twice as long. Turning the tablet off and charging that way doesn't help - the screen stays lit up while the charger is connected.

Trebel support means that it will take days instead of months to update to android p when it's out and a newer kernel means that we are a lot more secure.
