[Xperia Z3 Themes and Apps] Black Plague:
Latest version needs no root but it has no numbered row, I can make numbered row version but its better if u used [MENTION=4509922]perufaso[/MENTION] style of adding number row through Xposed per app setting and its more flexible. Root is required for later parts.

Guys i need your help

I was in stock rom 5.1 (XT1097, bootloader version 60.16) and sometimes i like to trie custom roms but at the end i always come back to stock, so today i flashed ressurection remix , then i return to stock by restoring my backup and got stuck on a screen with a dead android with a message that says not command.

i said wtf, luckily i still had the resurrection zip in my phone, flashed it and boot up ok. then i wiped everything, flashed the stock rom and again the phone didnt boot, stuck on the screen with the dead android

On the boot mode option i have

1 normal powerup

2 recovery

3 factory

4 barcodes

5 bp tools

6 qcom

the phone boots ok with options 3 to 6

any ideas why

==============

I solved the problem

reflashed teh rom and before i restart the phone i enter this command

mfastboot oem fb_mode_clear
[G4 Q&A, Help & Troubleshooting] dgoemans:
Hi all,

After installing some OTA on a stock G4, the phone has itself stuck in a bootloop, where i get a screen: "Security Error, authentication fail #9". I can get to the recovery, where the only option is erase all, but even selecting that goes straight back to the error.

I was hoping i could use fastboot to reset it, but no PC i plug it into (windows and linux) is picking up the device. As in, my windows device manager doesn't even see something new plugged in, and linux lsusb doesn't see a device either, so of course fastboot isn't working. Any ideas? I've done much googling, but couldn't find anyone with the complete set of circumstances i have. I'd prefer to not have to send it back :(

Cheers,

David
[G4 Q&A, Help & Troubleshooting] aquavalanche:

if not, I highly suggest you to send it back than fixing it yourself, as the development of G4 is not yet matured and this *could* be a hardware problem, IMHO.
[G4 Q&A, Help & Troubleshooting] rfarrah:
You don't say which model you have, whether you are rooted with a custom recovery, etc. If you WERE rooted with a custom recovery and you took an OTA (intentional or not) you could be screwed until/unless someone finds a way to address it.

PRESENTATION

Hi XDA-members;),

I present to you HADES-ROM. A custom ROM very fast and stable build for the Xperia E SS.:highfive::fingers-crossed:

You will need an unlocked bootloader for this. Unlocking the bootloader will void your warranty. Under no circumstances will I be held responsible for anything bad that might happen to your phone. If you make a Nandroid, nothing can happen. You have been warned.

When I first got G4 I put in SD card and set photos to store there which it did, last night I was taking photos and noticed the phone was storing them to phone memory and had been doing for a few days, I corrected it back to SD card and carried on taking photos.

This morning I moved the photos from phone memory to SD card but all these ones now a have modified date of 04/07/2015 by the side of them and sorting into date puts them in the wrong order.

Any ideas to get original date back? Cheers.

[Galaxy S6 Accessories] foreignfez:
Hi guys,

Just got an S6 recently and really don't want to put a case on it, so I thought I'd use screen protectors instead. However, I've yet to come across any that cover the entirety of the front or back glass. Has anyone found any like this that they can recommend? I understand that the glass curves slightly at the edges, which makes it difficult, but I've seen iPhone 6 protectors that specifically say that they curve at the edges, and hoped that someone had done something similar for the S6.

Thanks folks!
[Galaxy S6 Accessories] quangtran1:
I don't use anything but Moshi edge-to-edge tempered glass protectors for my iPhone 6, Note Edge, and now S6. They're a little costly but they're good stuff. In the US, they can be purchased at AT&T corporate stores. As far as the back, I use an inexpensive Skinomi back protector. It gives the slippery phone a lot of grip.

As others have stated the phone was only officially announced on the 28th of April.....It is essentially still just a baby.

Not to mention the fact that as it stands there are only a handful of DEVs that have root access. So just give it time, we all know how the game gets played and once the general pop gets hit with the root method then the custom ROMs will flow.

[G4 Q&A, Help & Troubleshooting] Z3ldaFan88:
It is really not. Sure the phone has been out for a little bit of time now, but for one it is not like our devs managed to all get one on launch day, so you have to consider the fact that in reality we have only been working on it for a short period of time.

Secondly, When you consider the fact that "Plan B" would be to staring down the phone and yelling at it to Root itself......I would say however long it takes for us to get a safe method of gaining Root Access is the exact perfect amount of time for it to take.

I don't know about you, but I would rather wait 3, 4, or even 6 months for something safe and not end up with a $600 paperweight as opposed to rushing it and ending up with just that.

The official unlock voids your warranty, so I do not expect to be able to ever relock the bootloader. Flash the Black bootscreen, and I figure there is a good chance they will not detect the unlocked bootloader status if you send in for something like a bad sim card slot.

Check your local laws, good chance that unlocking the boot loader does not invalidate the warranty.

Anyone try this? If so can you unlock it again?

I really doubt this works as the factory image UL-Z00A-WW-2.20.40.97-user.zip flashes both dnx_fwr_ann_a0-mofd_v1-ze551ml.bin and ifwi_ann_a0-mofd_v1-ze551ml.bin

More likely a flag gets changed inside a partition that is not touched by a normal flash. the factory partition is a good candidate. If someone with an unlocked bootloader could upload copies of /factory/mfg.fastboot.mfgget.out , mfg.fastboot.mfgset.out , Voucher_enc.bin, or if you could just make a zip or better a tgz of the whole folder I can compare it to mine and look for a difference that might be flagging the bootloader that it is unlocked.

[ZenFone 2 Q&A, Help & Troubleshooting] davepmer:
As long as you have the oem (ASUS) recovery, and OEM (ASUS) rom she will OTA from ASUS. That said the real reason to unlock the bootloader is to flash custom recoveries and custom roms. With a custom recovery, the OTA updates from ASUS just wont work. with a custom rom you wouldn't want the ASUS update anyway. But, some custom roms, have their own updates.
[ZenFone 2 Q&A, Help & Troubleshooting] cnsngr:

[ZenFone 2 Q&A, Help & Troubleshooting] Hawtpants:
Just flash the black boot animation and 99.9% of the warranty shops won't tell the difference anyway lol
[ZenFone 2 Q&A, Help & Troubleshooting] davepmer:
It should work, what happens? The Ota updates should be controlled by a cert file in the etc folder. The recovery has to be oem to do the update and as Ota updates are only the differences you have to have the previous oem build. The bootloader locked looks for a correct cert in the update to allow boot or recovery to be flashed. An unlocked bootloader just does not check the cert.
