Question: The tablet does not turn on after flashing

Acer Iconia B-A71
Android 4*
arm
I wanted to put ROOT rights. I went to the website 4pda.ru
It was written there that the firewood was official.
After installation, the tablet turned on once.
Now it won't load.
IN safe mode There are 3 download options:
SD Image Update Mode
Fastboot Mode
Clean Boot
Neither option leads to further action.
Acer appears, then disappears, the black screen shudders and the tablet turns off.
I need to reset the firmware and return it to how it was.
How to do it? Maybe I can somehow reflash it from a PC?

Answer: No. The commands don't give anything.
You need some kind of low-level formatting.
Only if the tablet is not visible from the PC, then the signals from the tablet are not coming and there is no access.

Question: What are the features of layout for tablets?

Can you tell me how the interface layout for tablets differs from the interface layout for smartphones? Well, the screen size of the tablet is larger (you need to take it into account) but what other points are there? Can you explain in more detail?

Answer: You need to draw your own markings for tablets, the only difference will be your imagination, the arrangement of elements can be completely different. If you simply copy-paste the markup into values-w...dp, either everything will stretch or shrink in the corner. Even if it is normal, as a rule, it will not look ergonomic and most likely will not be comfortable. You also need to consider the screen size (approximately 7 to 10 inches), orientation and view (single-panel/double-panel). But in general:

Question: The SIM card is not detected on Asus tablet ZenPad c7.0

Tablet for Android 5.0.2. It is unclear why, but it stopped detecting the SIM card after turning it on until I entered the “Dual SIM card settings”. If you enable data transfer in this state, the graphical interface crashes. What can be done about this and what can be connected with it in order to know for the future?

Answer: specifically with a specific SIM card, or with any one?

Message from waretwolf

What can you do about it?

Replace the SIM card, wipe the contacts with alcohol, reset the tablet to the factory

Question: How to remove the password on Samsung galaxy note 4

I can’t remove the password on my phone, I used to remove it without any problems, but now it doesn’t work. Maybe I accidentally turned something off...

Answer: HotBeer, thanks for the answer! I did it, but it didn’t help. There is an opportunity to change the password, but to remove it has disappeared somewhere, but it definitely existed before. I reset settings I did it, it didn’t help either. Even after this problem appeared, the battery began to run out very quickly, if before the charge lasted me for a couple of days, now it only lasts for half a day, or maybe a day if I don’t use it much.

Question: Charging the tablet via HDMI

How can you charge a switched off tablet via HDMI, since there is no unit (how to insert the cable and then into the outlet).

Answer: bring it to the workshop... if you don’t know basic things.

Question: Transferring a file from FTP to the Tablet download folder

Good afternoon, please tell me why the program, according to the debugger, stops at the line with new FileOutputStream(downloadFile1). The task itself is that I have to download files from FTP, copy them to the tablet in the download folder, read the information from them, and then delete them from the tablet. I download in the second stream, because... mostly it doesn't work.
I have 2 classes in total

Added after 10 minutes
It turns out that I connected to FTP normally, went through all the files in the folder I was looking for, found them with the extension I needed, but I just can’t download them.

Added after 2 hours 10 minutes
e.getMessage() produces
java.io.FileNotFoundException: /storage/sdcard0/download/666.xml: open failed: ENOENT (No such file or directory)
I understand that this says that a directory or file was not found, but I’m trying to write that I want to create it there, and I tried to specify just the directory /storage/sdcard0/download - it also swears, although on the Internet I found that when using internal memory The tablet indicates exactly this path. What am I doing wrong to download a file and burn it on the tablet?

Good time! Demo versions of Apple devices such as the iPhone or iPad are not very common, unlike the notorious ones. However, sometimes they come across on free sale (usually at a price much lower than the market price). Which, naturally, attracts the attention of potential buyers - after all, this is simply a great opportunity to save money. Who among us doesn’t want to keep our money? The correct answer is that absolutely everyone wants this.

Therefore, if you are just looking at such a gadget (or maybe you have already become its owner?!), you have come exactly to the right place - this article is just for you. Let's take a closer look at what kind of demo firmware this is, why it is needed and, most importantly, is it possible to do something with it?

Get ready... Let's go! :)

What does a demo version of an iPhone or iPad mean?

At its core, this is a full-fledged and absolutely working device from Apple, used as a demonstration sample in electronics stores. It is installed on a special stand so that any visitor can look, touch and evaluate for themselves whether to spend their money or not.

Naturally, as new models are released, old devices are removed from these stands and sold at a discount, and new ones are put up in their place.

True, if you purchased a demo version of an iPhone or iPad, this does not always mean that a lot of people managed to touch it. Sometimes it happens that a store receives several similar devices, but there is no opportunity to display them all. They put one or two, and the rest are in storage. Although this is more the exception than the rule.

What is the difference between an iPhone or iPad in a demo version and a regular one?

Despite the fact that inside it is absolutely exactly the same original and real device (processor, memory, etc. - everything is genuine), there is still a slight difference:

1. Equipment.
2. Firmware.
3. Box (with the inscription “Not for Sale”).

If we talk about the delivery package, then the box does not include a charger, headphones and other things. There is nothing there, only the device itself.

By the way, only “initial” iPhone versions or iPads are “demos”. That is, for a phone this is 16 GB of memory, for a tablet this is the same minimum amount of memory and the absence of a slot for a SIM card.

Regarding the firmware - a special demo has been installed software, a characteristic feature of which is a constantly appearing advertising video-saver (usually activated after 1-2 minutes if the device is not touched), as well as various restrictions - it is impossible to delete applications, settings are blocked, and a ban on changing various data is allowed.

All this is done with one goal - to give potential buyers a taste of all the “Apple magic”, but without breaking anything :)

How to remove demo mode on iPhone or iPad?

Since the demo mode is essentially a special firmware, you can disable it only by installing regular software. In short, you need to reflash it. However, there is nothing to be afraid of, everything happens in an elementary way. Three simple steps:

1. iTunes is also required.
2. Click restore.

That's all, after a while you have a full-fledged iPhone or iPad without any limitations of the demo mode.

Is it worth buying such devices?

Here everyone decides for himself, I will only tell you about the pros and cons.

The positive side of this purchase is undoubtedly the price. And now about what could be the catch:

• Constantly connected charging (this is how it is installed on the demo stand) does not always have a positive effect on the battery capacity. And if he's standing long time, then the conclusion suggests itself - with a high probability, the battery already holds a charge very poorly.
• It is necessary to remember that it begins from the moment of activation. As a rule, this happens upon purchase, but not in the case of demo devices. They are turned on and activated at the moment they are put on display, and it is difficult to immediately find out how long ago this happened. Therefore, there is a high chance of being left without warranty service.
• Natural abrasions and scratches are also typical for this type of device.

Of course, this all applies to those demo versions of the iPhone or iPad that were put on public display in the store, and not just lying in a sealed box somewhere in a warehouse.

Users of modern gadgets very often have a problem - the word “demo” appears on the tablet. Usually this only applies Chinese tablets low quality, there are rarely exceptions and “good” tablets suffer.

To get rid of this unpleasant and disturbing inscription, you can use different ways. Let's start with the easy ones, and if that doesn't help, let's move on to the difficult method.

First way. Regular discharge can help get rid of the “demo” sign on the tablet. Fully discharge the tablet until it turns off completely, and then charge it.

Second way. If discharging does not help, try resetting all settings.

Third way. If simple ways they didn’t help you, then all you have to do is reflash and upload the working version of Android, then the inscription will disappear 100%.

1. You will need to download the file (the file is safe, scanned by an antivirus), since sometimes it happens that some software triggers false alarms on such files, enter the password for the archive - 0987654321. You can search for the firmware yourself.
2. Unpack the package. You can unpack it onto a flash drive or tablet memory - it’s not particularly important. If you unpacked it to a flash drive, transfer the file to internal memory.
3. We start installing the firmware. We humbly agree with everything.
4. Turn off your tablet.
5. If a flash drive is inserted, remove it.
6. Turn on the tablet.
7. We enjoy the screen, clear of the “demo” inscription.

It happens that it is not enough to simply turn the tablet on and off. Press reset, to do this you will need to take a paperclip, straighten it and insert it into the hole. Then turn on the tablet.

If you encounter a problem such as the “demo” sign on your tablet, don’t despair, just follow the recommendations above, and then the “demo” sign won’t bother you anymore!
