[Xperia Z2 Q&A, Help & Troubleshooting] mshipXZ:
Well with this settings I usually got this SOT. Well today I got from 95% to 94% in battery within 8 minutes so 1% = 8min of SOT while google chrome browsing with wifi ONLY no other activities just browsing. No Youtube yet. With youtube only I got 89% to 88% in 5:30-6 minutes. @ 360p and 70% volume I think with 12/15 volume. Well with my cousins Z3, I got 1% = 8-9 minutes in Web Browsing and 5:30-6minutes in Youtube like my T2. With same settings Z3 was able to achieve what my T2 can. I wonder how Z2 will fare? I dont know if my test are going to be consistent but in what I test earlier that was the result.

- No Bravia Engine.

- Auto sync turned off.

- Just enterprised on in Device Administrators.

- GPS Location turned off.

- NFC turned off.

- Network set only in GSM.

- Stamina mode on.

- Queue Background on.

- Scanning wifi always off.

- No underclocking.

- Brightness set to lowest and no auto brightness.

- Wifi only.

- Phone in silent mode.

- Browse with Google Chrome and watch youtube 360-720p. With 80% volume most of the time.

- Facebook not log in sometimes I use Facebook Lite. Or not using any at all.

- Don't have any Twitter installed or Instagram. No syncing games.

- I don't do calls.

- No Tap to wake.

- shooting photo like a few sec or min.

- Rooted phone with no greenify or purifier.

- ALL apps installed are 57. I counted in my app drawer.

Running STOCK 4.4.3 Kitkat.

I think Xperia Z2 can do the same whike.browsing? Compared to my old lost Z1 which even witbout wifi It drains drastically. Even with reflashed firmware. I saw someone said that he drains 1% in 8-9minutes from his Z2 with his screen on.

I'm running EuphoriaOS (Euphoria-OS-1.1-ls980-OFFICIAL-20150622), which is a custom Lollipop rom. It's been working ok so far up until a few days ago, when my data connection just suddenly broke. Granted, the 4G/LTE wasn't functional before either, but I use wifi a lot and 3G is tolerable. But now I get nothing. Texting and calling are fine, though. I've had to mess with flashing APNs separately to get any cellular functionality before, but reflashing that to fix this new issue hasn't worked. I've googled how to fix this for hours, and I've tried pretty much every "fix" out on the internets. Still... nothing works. When I try to add APNs through the phone settings menu, it says "APN settings are not available for this user." I can tap the 3-dot icon and add the APNs and then tap Save, but the new APNs (or any existing APNs in system\etc\apns-conf.xml) are visible in the APNs settings menu. I tried resetting to default. I tried wiping cache. Tried reflashing the rom. You name it, I tried it. I guess the only thing left is to flash a stock rom and update prl and whatnot. That's a ton of hassle, and I don't even know if that'll work. I could only find stock kitkat roms too... would fixing data on a KK stock rom even do anything?

Help! Thanks in advance!

[Nexus 7 Q&A, Help & Troubleshooting] Mechixx:
Hello there everyone!

This is my first time posting, but have been using xda for awhile now as this community is amazing with all the work everyone puts in and the beautiful work they do!

So to get to the point. Ive been working on setting up the NERV Evangelion theme for my nexus 7 being a huge fan of the anime and love the look and functionality of the skin.

Upon setting this up, theres a choice to change the software buttons on the nexus 7 from the normal white 'back, home, and recent' buttons to custom ones that are orange to match the theme and also change the way they look.

I have it rooted and running AOKP with Nova launcher. and within the AOKP settings it allows me to add/change/move the software keys at will as well as change the icons etc. which is great, and works great! however after changing the button icons, as soon as i put it to sleep or the screen turns off, the custom back button icon changes back to the stock one whilst the others stay.

If i go back to change it back to the custom, it does it fine, but then as soon as the screen sleeps, again it changes no matter what. even if i have it in a different position...

So anyone have any ideas on this? no idea whats goin on, and cannot find anything on this subject and would appreciate the help a bunch, thanks!
[HTC Tornado] bdesmond:
Wondering if anyone has any ideas on how to reapir this if it's possible:

I have a TMO SDA which I apparently got confused and thought was an HTC Typhoon last night rather than a Tornado.

I decided to follow some directions to upgrade the Typhoon to WM6, and after the first reboot (http://www.geocities.com/gggbitonti/typhoon.htm), all it does is turn on to this white screen and not do anything.

Is there any way to repair this or is it KIA?

Thanks,

Brian
[HTC Tornado] tejasphatak:
Are you able to get into the bootloader mode.. Check by holding the camera button and connecting the USB. Please also mention what the screen says?? if it says tornado.. SPL 2.xxx something.. then its cool you can install a new system and your phone will be fine.. If not.. you are having a expensive paperweight...
[HTC Tornado] bdesmond:
No, nothing happens if I hold hte camera button and connect the USB cable. If i hit the power button it will just come up with a white screen - no messages. I let it sit for a couple hours like that and it was just a white screen the whole time.

Thanks.

[General Accessories] MeCJay12:
Let me preface this by saying this is my fist time posting here so if I screw something up, tell me and I'll fix it but I've gotten a lot of good information here about coding and other things so I'm going see if someone could help me over a little road block I've met in my current project. I am not a great electrician.

I'm trying to build a portable battery that will charge all my devices. I want it to have a common port to charge from, be lightweight, and relatively cheap (under $100). The two main devices I want to charge are my phone and my chromebook (power specs to follow).

Phone: Nexus 6p

usb type C

charger in box does wall (US) to 5 volt, 3.1 amp

3.1 Ah battery

Chromebook: acer c710

proprietary connector

power adapter does wall to 19 volt, 2.15 amp

2.2 Ah battery

Here's what I have so far. I was thinking of a usb type c input jack. The three power lines on it would be converted to 19.2 volt then stored in a drill battery. The drill battery could then be brought down to the 19 volt for a direct connection to the chromebook on one port and brought down to the different voltages for a type c port.

Here's why I cose these parts:

The types c input jack would be about to charge from a standard usb a wall plug with a cheap adapter and charge the battery, just slowly. If I get a charger for home that has a faster charge rate I could get really, really fast rates because of the type c 20 volt line when chargers for 100 watt type c come out.

the drill battery seems like a cheaper option than anything else plus the 19.2 volt storage would mean much less converting. I don't need a huge battery as you can see by the sizes of the devices' batteries I intend to charge. I can see there being a much better option here that I missed.

I chose the direct 19 volt out because it seemed easier that going to a 120 volt ac wall plug then back down (again I could see myself being wrong here).

lastly I chose a type c out basically for the same reason I chose it as the input jack. I can be made to charge and usb device with a cheap adapter. I'm not against a type c port and a type a port if that is easier or so easy that I just should.

anywhere you see something in this plan that could be done cheaper/better point it out. If nothing is wrong with this then all I need to ask is how do I wire a type c port with the different voltages?
[General Accessories] barbe31:
Good luck if you know what you do. Sometimes it's better to buy than to make;)
[General Accessories] AAnderson298:
I like DIY but I'd rather buy one from a trusted company.
[General Accessories] MeCJay12:
The problem is that no one makes anything like this yet. USB type c isn't well adapted enough. Closest thing is ones that charge with proprietary cables which I'd rather have a common cable everyone has.
[XDA Assist] XDA Visitor:
Dear All:

My work e-mail server got hacked and it went through a complete shut down to prevent further damages. We were told we will likely not be able to get access back to the e-mail we had before and will change to a different e-mail server with new e-mail addresses. However, I have copies of my work e-mails sitting on my phone now that I am able to read offline. A lot of them are useful information or conversations between myself and my clients so I like to be able to copy these e-mails and save them on my PC so I can view them before they are deleted from my phone.

I have adb installed on my PC and like to know if anyone knows where e-mails are stored on our phones so I can copy or move them to my PC. My LG G3 is rooted so I have full access. If anyone can share any thoughts, I greatly appreciate it.
[XDA Assist] OfficerJimLahey:
Hello, and thank you for using XDA Assist! :cowboy:

Interesting problem...probably compounded by that if it's work email (like me), there's a layer of encryption as well.

Also, the stock email app, like many stock apps, is rarely standard across OEMs. So their storage may differ.

Backing up your /data folder would be a good assumption, yet that won't give you anything readable by the PC.

A good place to start is your device Q&A thread:

> LG G3 > G3 Q&A, Help & Troubleshooting > [FAQ][HELP THREAD] LG G3 | Ask any question | FAQ in first post [Noob Friendly]

Please note, you will need an XDA account to post there.

Hope this helps, and good luck! :)

Yes you can downgrade to 5.1. But absolutely do NOT take an OTA to 6.0 because it will almost certainly cause a brick.
[X 2014 Q&A, Help & Troubleshooting] tyus2:
The bootloader in 6.0 marshmallow on XT 1092 is exactly the same as 5.1 (60.16). In theory, I think it would be possible to downgrade to 5.1 via image flash and then OTA update to 6.0.

As a matter of fact, I flashed Brazilian Marshmallow on my XT 1092 (except the bootloader and partition table) and then downgraded to 5.1 image today, and took the OTA to 6.0 from Motorola. Phone works fine, and I see the bootloader is same as before.

What if the 6.0 update has same bootloader and partition table as the 5.1 firmware? It would be safe to restore to 5.1 and take the 6.0 OTA then? I see that the bootloader is same in Marshmallow as Lollipop 5.1 (BL ver-60.16).
[X 2014 Q&A, Help & Troubleshooting] Gus.Ottawa:
I flashed the full RETCA 5.1 firmware over the RETBR 6.0 and it's working fine (even flashed the bootloader and partition table). But I have no idea when, and if, I will get the 6.0 update for Canada, as we are always the last country on earth to get the updates (if at all).
[X 2014 Q&A, Help & Troubleshooting] AGISCI:
Theoretically yes, but there is one problem in your assumption. Remember that there are different models, xt1092, xt1093, xt1094, xt1095, xt1095, etc. Sometimes the different models might be different bootloader and partition tables. So for example I change from xt1092 to xt1097 brazil for 6.0. But if the brazil bootloader and partition table were different there it could cause a brick. It is better to warn people about the dangers of downgrades because it is a large cause of bricks. For example i had this happen to a friend. He had a moto g on 4.4.4 from chile. He then flashed the 4.4.4 from europe to take an ota to 5.0. It worked. But the bootloader and partition from the 5.0 from europe and the one from south america were not the same. So he went back to 4.4.4 from south america then took the ota to 5.0 and it bricked. The moral of the story is that the bootloader and partition table for 5.0 in one model is not necessarily the same in another model. If you are 100% sure that the partition did not change when you upgraded then sure taking an OTA is safe. But remember that many of these people are changing their phone to the brazil 6.0... so when they downgrade and revert to their correct firmware there is a high probability of brick from an OTA from the difference in bootloaders and partitions. It is better to warn them so that they don't end up with a phone that is bricked and no way to unbrick it.
[X 2014 Q&A, Help & Troubleshooting] supremekizzle:
So as of right now since I flashed Brazil 5.1 and then flashed Brazil 6.0, there is no safe way to get back to US 5.1 to take the 6.0 ota. The best course of action is to flash XT1095 6.0 when it's available, which should be the next week or so?

But it won't be just flashing the ota, it'll be flashing everything in the firmware to get back to US version?
[X 2014 Q&A, Help & Troubleshooting] AGISCI:
Yes, you will have to flash everything.
