[Nexus 7 Q&A, Help & Troubleshooting] moiloon:
has anyone had any further success getting multiple cameras to work?

i myself have a rca rear camera installed, using easycap viewer, and also using a android head unit usb camera in conjuntion with the app usb camera by shenyao china in playstore for dashcam, but im having a dam hard time getting them to work in conjunction, as with the usb camera app, i can background record from the front usb camera, but if i then engage reverse, easycap viewer opens but just boot loops, so im now looking for maybe a hardware solution to switch cameras by external means, maybe relays, but im no electrician, and cant find any info if this would be possible, was thinking just using relays of some description to switch the power on an off, when rear camera is initialized relay will cut power to the front camera and vice versa.

Does this sound feesible?? if so what relays would i need?

was looking at some of the auto camera switching relay boxes on aliexpress, but they only accept rca connection, which is no good for my setup, front is usb and rear is rca via easycap, now i could get a rca camera for front, but then i could not use the app on the nexus 7 usb camera to background record ect ect

ive tried defaulting the dashcam to usb camera app , and the rear to easycap viewer, and like said above it just boot loops easycap viewer as the front camera is running in the background, and shows that both cameras connect and disconnect over and over

even thought about 2 easycap devices and usb cameras and i think id be in same boat, boot looping

what is very strange though is that whilst pulling my hair out trying to find a solution, i also have a wifi transmitter for rear camera, this worked poor as a rear cam due to delay/lag, BUT i could have the front camera background recording via usb camera app and also view the rear camera picture with reverse engaged without any conflict, but had to manually open the app for the wifi transmitter (wifiavin) to see the picture, which also was a pain

anyone got any ideas if a hardware solution to my problem will work, and parts and links would be fantastic
[Nexus 7 Q&A, Help & Troubleshooting] ScrapMaker:
Curious on this as well. Would love the ability to create an app to open to a specific app. Both my USB webcam and frame grabber are treated similarly by the OS, meaning all the same apps can use either camera. However I've noticed my USB webcam takes priority. If I already have it plugged in and hook up the frame grabber, it still opens the camera app right to the previouslyplugged USB webcam.

I too, would rather avoid the relays, but that might be the only way.
[Nexus 7 Q&A, Help & Troubleshooting] moiloon:
already tried the5v relay route, worked on bench great , but not in the real situation in my car install still looping both apps, due I think to the response time of the relays switching from one device to another grrrrrr

i just downloaded from playstore dual usb camera by shenyao china, new app by developer, now I can use this app so long as it its opened 1st after my tablet loads after re awake from sleep, then selecting reverse easycap opens as expected, rear camera is viewable, then after reserse deselected, front camera is reconnected and viewable on the screen with usb dual camera app once more, works flawlessly, but its missing the auto record and send to background ect that the usb camera (not dual camera app) app can do, emailed the developer to ask if these can be added to his new app, as of yet no reply, but my fingers are crossed

edit- just had a reply from the developer and he says hes going to incorporate the missing features from the dual usb camera app, but will take a little time, happy days
[Nexus 7 Q&A, Help & Troubleshooting] ScrapMaker:
I am a bit confused by your comments... you're not implying that you have to interact with the screen to switch between forward/reverse cameras, are you? That would be unacceptable for most people.

What I can tell you is I have a HIGHLY reliable solution using the relays and Tasker. Here's how I have it set up right now:

- Forward-facing/parking camera is always on. USB 2.0 IR webcam.

- When relay has UVC framegrabber/rear-view camera disconnected, Vcam2 brings up forward-facing camera by default.

- When my car hits reverse, I kill vcam2, then re-open (using rcjoycon.) This is as long as it takes for the device to be recognized and pop up with reverse view.

- After I leave reverse, I have a timer relay to wait 5 seconds to kill the framegrabber. At that same time, I kill vcam2. If I was ALREADY in vcam2 before going into reverse, I have tasker re-open the camera. Otherwise, it just falls back to the previously-open app.

It may sound difficult but it's not all that bad. Now, if I could somehow get an app that allowed me to specify a hard-coded camera mapping, I would pay good money for this.

Imagine a tasker-controllable launch of each camera view. I would enjoy this, so I could potentially record all cameras full-time, despite what I choose to view. I have a feeling the tablet would drain awfully quickly while recording, and a dedicated dash cam might be more realistic. I really do like the idea of a hidden dash cam though, that cops/criminals might not notice.

I offset the unavoidable drain on my N7 by using yet another timer circuit. When my car turns off, the tablet stays powered for 30 minutes. I detect the loss of power through my rcjoycon, which tells tasker to go into airplane mode, and gracefully shutdown what it can, then kill the rest, and turn off the screen properly. With this setup, I have no issues. I am considering installing a switch to allow the tablet to have power 24/7 for when I am away for extended periods of time. Since I leave my car on a battery tender during those trips, it could be handy to have potential connectivity to the tablet over Wi-Fi. (Just thinking out loud.)

I didn't do that at all due using Ubuntu, I download flash tool, I used the bell firmware didn't exclude baseband (they use the same bands plus h+42 for T-Mobile in case this phone has it). Rooted it and added a recovery, flashed a 4.3 ROM by our doomlord and flashed superuser update thus 4.3 no bloat and got LTE working on T-Mobile

[Sony Xperia T, TL, TX, V] bsined:
Which rooting script did you use? I couldn't find a working one so I had to wait for a good flashable release. How's the battery life on Bell firmware?
[Sony Xperia T, TL, TX, V] Durteedee:
I used the one that came with the flash tool 4.1.2 only, battery life wouldn't know it was only on the bell firmware for about 30 mins at most before flashing doomlords 4.3 ROM

That's strange. I've tried every single root method in Flashtool and none of them worked on 4.3.

Because I rooted bell 4.1.2, 4.3 can't be rooted yet without an unlocked bootloader

Thanks for this. Its been a long time since I've upgraded, came from XperimenT 3.5, and I wasn't sure where to start reading first. I'm curious though. Do you know if the cpu control is working for us locked bootloaders?

Also, do you know how to get rid of this "close all x" button at the bottom of the recent apps list? It covers the bottom ago in the list. Plus I like the one in the top corner thats enabled by gravity box. I'm not sure how it even turned on. I don't remember it being there at first. Even disabling all the xposed modules doesn't remove it.

[Sony Xperia T, TL, TX, V] bsined:
- Judging by the CPU states reported in BBS, governor changes are working. Though I'm also using CPU Tuner for automatic downthrottling.

- "Close all X" is a part of the ported Z2 UI. There's a request to remove it in the ROM thread.
[Sony Xperia T, TL, TX, V] Happy-J:
How did you root? is it the dual recovery that does that? or another method. Just asking as I understand that rooting the AT&T TL is extremely hard.
[Sony Xperia T, TL, TX, V] bsined:
Dual recovery will prompt you to root the phone on reboot during installation and the new ROM retains root access. However, rooting 4.1.2 on its own was very easy, too - the scripts provided on the forums work flawlessly.
[Sony Xperia T, TL, TX, V] Happy-J:
Thanks for the quick reply and answer. One last question for you, can I use flashtool to root 4.1.2?
[Sony Xperia T, TL, TX, V] Durteedee:
Yes its what I used for my att TL

[Sony Xperia T, TL, TX, V] Happy-J:
Thank you for your help, I think I'll be installing this very soon!
[Sony Xperia T, TL, TX, V] bsined:
FYI: the install might fail if the phone is rooted by a method other than the one included with recovery. If that's the case, see the bottom of the guide for troubleshooting - just don't forget to backup your existing setup before trying to flash.
[Sony Xperia T, TL, TX, V] Happy-J:
Ok, I will keep that in mind when I start the installation, and just use the recovery's root. Thanks for the tip.
[Sony Xperia T, TL, TX, V] Happy-J:
I can't seem to get into recovery. I have tried pressing volume up at said time, and long pressing, but no dice. Can anyone offer assistance?
[Sony Xperia T, TL, TX, V] bsined:
Did the phone boot into recovery during installation? If not, you need to reinstall it. If yes, there's now a new app called NDR Utilities - use it to boot into PhillZ Recovery. Otherwise, please ask the recovery script author.
[Sony Xperia T, TL, TX, V] Happy-J:
No, the phone did not boot recovery any of the times I reinstalled it, which was about 5. I am going to try flashing back to stock and try it again. Thanks for the helping hand again, very much appreciated.

---------- Post added at 01:07 PM ---------- Previous post was at 12:59 PM ----------

OK, a clean flash of the stock firmware did the trick. Thanks again for the help.
[Sony Xperia T, TL, TX, V] bsined:
Was your device rooted before? I had issues installing that recovery only when I was running European .145 firmware. I hope that wasn't the case with you. =)
[Sony Xperia T, TL, TX, V] Happy-J:
Nope, didn't have no root access, stock AT&T firmware. However I was using Helium Backup for my backups. Not sure if that was the problem, but reflashing the stock firmware fixed the problem, whatever it was.
[Sony Xperia T, TL, TX, V] Happy-J:
Anyone else having problems with play store refusing to connect? I have tried everything I think of, to no avail. Any advice?

Nevermind, If you're having issues with Play Store not connecting just flash GApps from here http://xdaforums.com/showthread.php?t=2397942 use the 4.3 package. That will fix the problem most definitely.
[Sony Xperia T, TL, TX, V] bsined:
Try connecting on Wi-Fi and let it sit for a few minutes after installation - it needs to update itself and Google Play Services.
[Sony Xperia T, TL, TX, V] Happy-J:
I tried that, along with a few other possible fixes that I found on the web and nothing worked. However just flashing the GApps package through recovery worked for me to get it back up and running.

SIMPLER GUIDE

1. Install FlashTool

2. Download 4.3 Central European FTF

3. Flash 4.3 excluding the baseband

boom!
[Sony Xperia T, TL, TX, V] bsined:
And lose your data and root access. Read the subject before trying to be the smart guy.

I keep getting this Unfortunately, "NFC service has stopped", and it won't let me get past the first screen. I've re-downloaded the Rom I've done all troubleshooting. I've even tried to flash with different recovery's. Any help would be appreciated greatly :confused:. If it matters i'm coming from the Xperiment rom
[Sony Xperia T, TL, TX, V] redincali:
It's usually because you didn't do a complete wipe before flashing. Do a system format, clear the cache, then clear dalvik cache in advanced options. Then flash the rom, and the update_supersu.zip after.

[Sony Xperia T, TL, TX, V] victor_pv:
I had the same problem, and I was coming from Xperiment T. I had other problems and flashed a couple of stock roms before getting everything right, but I did not have to delete my data.

What I think that solved the NFC errors was installing the Bell 4.1.2 stock version with the flasher. Just clear the box about clearing Data, so you don't lose your data.

Let the phone boot with that one, it will install and NFC update, and you should have all your data and settings.

Next root that one and install a recovery bootloader (I used CWM v8) and install the 4.3 Purex.

If that doesn't work let me know and I will tell you everything I did (but I had other issues aside of the NFC error).
[Sony Xperia T, TL, TX, V] MaxVenkman:
Thank you for posting your upgrade.

I am having a problem installing this. Edit: I figured out the problem installing it. For other users, if you have a problem, you might double check to make sure you downloaded the Ultimate PUREXT Rom, *and* the OTA update. Originally, I only had the OTA, it was not pretty. Install both.

So mission accomplished, *but*... my Sim is still locked. I'm so glad to have all that AT&T software off the phone and be rooted. But how do I unlock it to use with my local network?

Thanks!

[Sony Xperia T, TL, TX, V] s_goff:
I was also having trouble getting into recovery (either of the two), but was successful after re-flashing the stock AT&T fw again (had flashed it once, but still wasn't working after the first time), and rooting via Flashtool with SuperSU *first*. Then, I attempted installing dual recovery with the most recent installer version, using the installation option indicating root with SuperSU. After doing this, it booted into touch recovery during the dual recovery installation tool's process. It had not done this in previous attempts. I haven't gone further with updating to 4.3 on my TL yet, but i wanted to post about this, hoping it helps anyone having similar problems!

: Confused:

hi i upgraded the firm to 4.3 x also ok. But I realized that the 4.1.2 was much more powerful, so I would go back to my version 4.1.2 at & t unlook. I did the backup and recovery explained by the guide that I created this folder (1970-01-06.16.45.24_9.1.F.1.120). my doubts are:

- The firm 9.1.f.1.120 unlook I could not find it on the net I can retrieve it from the folder created during backup? how?

with the firm-4.3 I no longer have the 4g lte I tried the steps but it did not work, there is another way to recover it?

- The phone loses signal often and always works on the -100 db there are systems to enter a European band that increases the reception?

thanks to all
[Sony Xperia T, TL, TX, V] bsined:
If you have the backup, just boot into recovery, then tap Backup and restore -> Restore from /storage/sdcard1 -> select your backup -> confirm.

For LTE fixing, see the guide. If the signal is weak (like where I live), the phone will drop to HSPA+ automatically and will pick up LTE later.
[Sony Xperia T, TL, TX, V] sisma1:
I reinstalled the 4.1.2 reception has improved (although I do not understand why, since I had installed the radio bands present in the guide but without success) the fluidity of the phone is much better (it was very fluid with both roms, only with 4.1.2 you will notice the difference) is a little worse sound. the root is left and I started to delete useless apps at & t, now I think the best thing to do. or are there better than the 4.3 purext v3 rom? grazie
[Sony Xperia T, TL, TX, V] bsined:
There're certain settings by at&t that are stored inside build.prop and a few other files that control how the radio behaves. I'm not a developer so it'll take me a while to figure out (I think I'm on the right track for this - I'm consulting with developers). My phone also suffers from intermittent reception issues so it's very much in my interest to get it fixed. Unfortunately, my schedule over the next month or so doesn't allow for a dedicated day or two to be spent on this - it's a huge chunk of work that needs to be done in one sitting. If you feel comfortable reading over thousands of lines of bash script/config files, PM me and I'll explain what I'm trying to do and how you can help.
[Sony Xperia T, TL, TX, V] sisma1:
hello thanks for the replies.

*today I made ​​a new attempt I reinstalled the rom 4.3 but I have not installed LT30_JB NAM 4.1.2 Baseband only_at & t.zip

- I disassembled the phone and I added a strip of aluminum (see htc s ) just above the antenna cable to the signal seems to be improved by -3/-5 db tested before and after with the menu # * # *4636 # * # *

- Now the thing that I would like to understand is another , basically my phone makes me be unreachable phone calls although signal is present , this happens when it is idle ( this was before aluminum are now in the testing phase )

- I compared most phones on the move in the car, and it seems that the sony xperia face more difficulty than others to break away and tie in the new cell.

the next test I will do is to flash the baseband with 4.1.2 jb strip of aluminum to see if I lose or gain signal

in any case I am available to work as a team to solve the problem, even if my English translated by google is bad, and they are not practical programming

hi i need help

I flashed the stock rom 4.3 skyfall tim 9.2.a.0.295, but I lost the cwm and root permissions.

I tried to install the bin4ry tool, but without success

I can not get into recovery with the power button and volume + (cwm disappeared)

I can not restore backups made ​​by cwm on external sd

I ask if there are any links or methods to get root permissions and install cwm again

Flash back to 4.1.2, install recovery, and restore your backup. If you want root, follow my guide. There's no way to root 4.3 other than flashing it in recovery over 4.1.2.
[Sony Xperia T, TL, TX, V] sisma1:
thanks

so you can not maintain the permissions with root and cwm 4.3 skyfall tim 9.2.a.0.295 and even get them back once lost

I say this because the line was improved with this rom

I'm testing them a bit :) thanks

and load the flash tool can not upload this baseband on 4.3 xt v3.0 as well?

or is there a way to get root permissions with the 9.2.a.0.295?

If you install 4.3 by flashing any FTF, there's absolutely no way to get root access.

The FTF attached to my guide contains only USA baseband (LTE4 & LTE17).

Hello I write what I did just to help those who need it ... (my not meant to be a guide but only the sharing of tests done on my sony tl)

I had the annoying problem of the line was disconnected in the 'waiting to reconnect on lte, consequently those who called me I was unreachable. I want to clarify that my test has no comparisons with other phones to know for sure if the improvement applies to everyone.

I installed it on at & t sony tl unloock 4.1.2. Stock, 4.3 x rom v3.0 as a guide

- Then keep following the guide I installed the 4.1.2 baseband AT & T attached to the guide

- Not happy with the signal. I flashed the baseband of 9.2.a.0.295 skyfall tim Italy.

- I also added wcdma prefered menu * # * # 4636 # * # *

The problems that I mentioned seem much improved or almost completely disappeared

- I have not lost root permissions and everything seems to work

P.S. my baseband is now in info phone 8960-a-aaaaanazq 10015031-61
[Sony Xperia T, TL, TX, V] jonchance_84:
I have always flashed baseband from AT&T 120 firmware (4.1.2) on my TL. Then using *#*#4636#*#* to get LTE working, but I tried your method here out of curiosity because I sometimes lose connection also (living in the country in Texas). Surprisingly, I do see an improvement in signal by 5 dB's and in Mobile Networks menu, there is actually an option to select LTE directly without having to go into phone info the old way. I'm now using DarkLord's v4 4.3 based on IT Skyfall 205 and the baseband you suggested from 295 IT Skyfall. This seems to be a perfect combo for us AT&T users stuck with the TL. Great work my friend...
[Sony Xperia T, TL, TX, V] bsined:
The baseband thing is quirky. I did an experiment a few weeks back of flashing a few 4.1.2 ROMs and then flashing the at&t baseband. Turns out that the baseband version changed only based on the main ROM. Flashing at&t baseband had no effect on the version but did allow for LTE connection. I've been meaning to compare at&t's build.prop with others in order to create one specific for TLs but haven't had the time yet.

I said in the guide, that all questions about the ROM should be asked in the thread about it. Read this and the posts below it. Nobody knows what it does for now.
[Sony Xperia T, TL, TX, V] bsined:
Do you still have the "normal" LTE access? It worked for me but after a reboot, it all disappeared. I've tried to dirty-flash the ROM followed by baseband FTF flash with no luck. Editing build.prop to set the default network to LTE doesn't help either.
[Sony Xperia T, TL, TX, V] jonchance_84:
telephony.lteOnGsmDevice=1 ro.telephony.default_network=9 ro.ril.def.preferred.network=9

Just did some research and this is what i came up with. After I would reboot, LTE wasn't enabled by default. The first line is changing Cdma to Gsm and changing the 0 to 1. Then changing default network to 9 (basically the 10th item in *#*#4636#*#* phone info menu). This basically sets it as default when phone boots. The third line is a totally new addition.

I've rebooted 10 times and LTE is connected immediately.

I guess the best solution is to compare these values in build.prop in the 120 firmware just to be sure.

EDIT: I also don't have LTE as option in network mode in network settings as I did right after flashing baseband from IT skyfall 295. Not a big deal.
[Sony Xperia T, TL, TX, V] bsined:
I think part of my problem was GravityBox's smart radio. It was messing things up because LTE wasn't being recognized properly on the system level.

Nonetheless, this whole situation is very strange because LTE was selectable at first through Network mode. I think I had rebooted the phone several times before it disappeared, so I wonder what broke it.

I've previously tried default_network=9 (that's actually the only setting in .120 build.prop) but it has never worked.

Also, these changes to build.prop require cache & Dalvik cache cleanups. I was in a perpetual boot loop until I figured that out.
