OTA updates don't wipe the device: all apps and data are preserved across the update. Even so, it's always a good idea to back up your data frequently. As you point out, not all apps support the in-built Google backup mechanism, so it's wise to have a full backup just in case. See our backup tag wiki and top questions to learn about what options are ...

For Galaxy Nexus these are different builds: takju: devices sold through the Play Store in the US. Contains the Google Wallet aplication. yakju: devices sold through Google outside the US. yakjuxw: devices sold by Samsung. If you buy yakjuxw I would recommend that you update to yakju with factory images provided by Google. This way you will get the ...

If the date of activation matches the date of adding your Google account to the device, there's an easy way to check (unless you did a factory-reset in the meantime, and had to re-add the account): with your Google account's credentials, log in to the Google Dashboard Scroll to the section labeled "Android" and expand it (by clicking its title / the LGM [...

I found out how to do it with the official firmware from asus.com. I'll post this for the benefit of all sentient beings future readers with the same problem. I'm writing this in a very beginner-friendly fashion. Note: I had stock recovery. These steps will not work if you have a custom recovery. Disclaimer: This is only what worked for me. It may or may ...

The info of this exact firmware is shown on this page. As written, G930FXXU2EREM is the PDA version, and G930FOJV2ERE8 is the CSC version. PDA represents the "core" OS build, while CSC - "Consumer Software Customisation" or "Country Specific Code" (didn't find an official explanation of the acronym) - represents the region-specific customizations. The two, ...

There can be several differences, or reasons for having two firmware versions. Sometimes there are two completely different hardware variants, sold in different regions. For example, the Samsung Galaxy S III has a variant based on a Snapdragon MSM8960 system-on-chip (SoC), and another based on an Exynos 4. Because the hardware is different, the variants ...

By workspace you mean homescreen ? You could try a custom launcher, like Apex or Nova, which allow you to backup your homescreens.

It's device internal codenames. Reasons: Device specifications is secret before release. After release, firmware not renamed, to exclude misunderstanding for developers. One device may have different firmware versions, depends on target market and hardware configuration (modem, NFC, Wi-Fi settings).

As for your first question: no, wiping data from the recovery just wipes the content of the partitions, not the partitions themselves. So your device's disk will still be divided into /data, /system, /cache etc., but those partitions will be blank. As for your second question, yes, you will be able to restore the stock firmware, as long as you make a backup ...

4 years is ancient in tech years. Your first pic holds your answers. The model Gt-p5110 and with Google it states that it was released in 2012. Came with android ice cream sandwich 4.0.3 and it is upgradable to android jelly bean 4.2.2. Also if you look at the kernel version you will notice that it was compiled in 2013. For update firmware you could check ...

The first part G930FXXU2EREM is the "serial" for this ROM. The second part G930FOJV2ERE8 is the "serial" for "previous" ROM (i.e. before an OTA update). TUR is a region code, this case it's Turkey. So you can think it's: {to}-{from}-{region}.zip

Is the firmware really stored in another eMMC than the Android firmware? No. Baseband firmware, kernel and userspace Android are all stored on the same eMMC (there might be some exception but I don't know of). Some SoCs have boot area partitions which are somewhat isolated at hardware level (usually used for bootloaders) but technically those are also on ...

1) You can boot into TWRP recovery from fastboot fastboot boot twrp.img 2) Then you can backup your whole emmc from adb adb pull /dev/block/mmcblk0 Does /dev/block/mmcblk0 include my internal storage, my app data, contacts, sms, wifi passwords, bluetooth pairings, system settings etc? Have you personally tried that method on an encrypted device? It ...

Please check the backup tag wiki, which already gives you some "first-aid" advice. Take a closer look at the Nandroid section, as that is what you will need: First, you will need to install a custom recovery (see e.g. recovery-mode). The most common choice here is clockworkmod, as it is available for most devices. Depending on your device, there might be ...

OTA update will depend on the CSC of your phone. CSC is Country Sales Code; it tells you which region your phone can be used in and which networks it will work with. If you are in India (and your phone is connected to an India network), and your phone has CSC for Saudi Arabia, you will not be able to get OTA updates. What you can do is flash a stock ROM for ...

I had the same problem, did everything I could think of. Finally last night, I decided to try something different. I ran Kies in "Compatibility Mode for XP SP3" it took forever, left the phone plugged in while I went to bed, woke up this morning with 4.1 finally on it. I run a Windows 7 Premium Home 64bit. Not sure if this will help with everyone's ...

Just run the Kies with Administrator permission. For windows 7 right click on the "Samsung Kies" or the "Samsung Kies(Lite)" version and select "Run as Administrator"

Summing up from the comments: No "reset" will ever roll back any system updates applied. For that, you would have to re-flash the original ROM. For the device to show up with adb devices or fastboot devices, you must have your computer configured accordingly. If your computer runs Windows, you will need a special driver (Koush's Universal ADB driver might ...

According to the manual for your tablet, there should be a "Reset" button. Try holding it while powering on the tablet and see if it boots into special mode (recovery) that lets you perform a reset.

"Fastboot" is another name for the bootloader. On the devices I've used (Galaxy Nexus, Nexus 5, Nexus 10), the bootloader is stored in a partition called "bootloader", and you can use it to overwrite itself by running fastboot flash bootloader (filename) from a PC. Overwriting the bootloader partition with something that isn't a working bootloader will ...

It depends and differs by the mobile manufactures. For Sony, Samsung and Motorola devices you can find in Settings > About phone > Build Number. If you have a Samsung device you can also check the version of firmware you currently have by dialing *#1234#. In HTC devices it will be under Settings > About Device > Software Information > ...

To answer the question, no. It's not possible to extract firmware without having an unlocked, rooted Moto G. To help with your original problem, see this thread on xda-developers forum (assuming you are talking about the original 2013 Moto G, and not the newer 2014 model.) It has step-by-step instructions for flashing stock firmware onto Moto G. It links ...

Huawei P8 Lite: This is the basic model; design, UI and features are usually assigned to the model name.

Modular may offer official long-term support Not quite ready today are modular phones, like that for Project Ara. Be aware that the schedule for modular phones has already slipped by years, so I would still treat the dates as questionable. Due to their modular nature, the expectation is that they will continue to be supported for a long time. Update: ...

Other answers mention that aftermarket distributions can provide you with security updates. This is only true to some degree. They usually integrate low level-code (proprietary blobs) from the manufacturer and those parts don't get updates after support from the manufacturer ends. The same is true for firmware bugs of hardware components. (e.g. Broadpwn) ...

Are updates digitally signed before being shipped? Yes, updates are cryptographically signed by the publisher. This is to ensure the integrity of the update, both from unintentional corruption during the transmission, and willful manipulation from an attacker. Who signs the updates? Is it Google? That depends on who publishes updates for your phone. If ...

I then tried uninstalling Gmail by deleting the file and then trying to reinstall it from the play store You can't install it from the Play Store, you can only update an existing version. This is to prevent phones that haven't met Google's official criteria from getting the core Google apps, though there are workarounds (see below). the apk deletion ...

The progress bar being stuck for a while is not unusual as progress bars are fairly difficult to get right. An update taking more than half an hour, on the other hand, doesn't sound right to me. Of course your phone could simply be slower at this task than mine.

Connect to kies in this mode as shown in your photograph. Follow instructions for emergency firmware recovery. It worked for me.
