HTC Desire 616 Dual SIM does not turn on

It is like that. The phone is Kitayuz, that’s it. However, I'm trying to raise this body. It came with a periodic shutdown, in principle, it turned on. I think, well, there is a business for a couple of minutes – I’m plunging and that's it, it wasn’t there. I have been unit with the device for 4 months from time to time.

What was done: after the tinning of the CPFLEKIKP, the phone fell off in general, i.e. We clamp the inclusion button Visit 280mas, release – we fall in 0, while there is no start and heateds everything allegedly works. Well, I think it is necessary to skate – I skated, the situation is the same, absolutely. Replaced the percent – to no avail, the same. He replaced 3. Flashki from Samsung, and threw exactly the same as his native – one outcome. We draw conclusions that percent and flash drives are in order. We go further – skipped the RFA, replaced the RFAK – in the same way. The KP remains, which I do not have, but, having looked at the neighboring board from 816 HTC, where all the details absolutely coincide (the remaining periphery) that all the stresses are present, I list: 1.8, 2.8 to Fleh, 1.2, 1.8, 2.8, 3.3 on CPU -called out of Mapkarta, everything that is possible, without cliffs in the range of KP – CP. Quartz generates frequency, i.e. The initial phone 50-90ma on the rise of the pen takes place, then 280mas. Shorty, leaks (the multimeter went through the entire board), do not – excluded that it is rolled up in 4 months 30 times for sure.

Fleha replaced was carried out in a standard way through the merging of the old dump, the flood of the new. He did not plow on the fee – Flah was thrown into the Xsa, i.e. The power no could not leave.

I also exclude the cliffs of the CP – Flash also exclude, “Loss: D” Each nickname CP and flash drive with a needle. I called the adherents of the CP-flash, there are no breaks, there are no cliffs-including measurements of the imprisonment resistance-all within 0-1 Ohms.

In general, friends, help out with thoughts – already exhausted. 4 mikrukhs are required for launch: CPU, flash drive, RFC, KP, only if there is no Bat_ok signal on the charge chip there. I have FAN5405 on the board, and it does not have such a signal. I cut everything that is already possible, there is no sense and changes. Thank you in advance.

Set Mikrukh Standard: MT6592V, Flah is noble, MT6322GA, MT6166V

I put it to replace the Communist Party.

And you win AB-mobiiil. ©

In general, on the topic: the device was sewn with a broken KP, connected to the PC, the KP issued all the shoulders. I searched for the officers 100% working MS – I never found it. I spat, it turns out 6322GA can be replaced with 6323GA without loss of performance. Figure 1-V-1, voltage +-0.1 V. Prevroders with spelled flash drives took from TPS7900. – With them the flight is normal

It turned out I have a team of a hodgepodge of 4 devices. KMK7X000VM-B314 flash drive (instead of 4 GIG-8 GIG), MT6592V, KP MT6323GA (instead of MT6322GA), RFC MT6166V.

And all because it is not enough to start the stresses)

OK then. In my understanding, the launch of the device is as follows:

1) When the KN Clips Clouds (no matter 1.8 or 3.3 volts on the button), the voltage is dropped on the pwr_on bus – hence the KP understands that you need to apply for the crusts for the RFAC and turn it on
2) As soon as the crust arrives at the RFA, it starts, and begins to swing quartz, the frequencies swing to the minimum threshold for the start of the mind – all this goes on the CLK tire (I don’t remember with which prefix). – In parallel, the food with the KP has already been given.
3) As soon as the percentage receives the minimum frequency – it picks up it, swinging, turns on, redirects the generated frequency already relative
4) the response of the flash drive to which, along with the promotion, the voltage of the clamping of the inclusion button was given (it is not necessarily true, it may at once scatter all the seals of the CP). If the answer of the flash drive and the RAM is obtained, the device is already turned on according to the plan prescribed in a preloder, then in Bout, then in android.
5) Further, the voltages are already controlled programmatically. What is the nutrition of the loser, that flash, what charges, that any periphery.

It follows from clause 5 that you can disperse the phone if you make your firmware with your handles from scratch.

How does it really happen? Of course, I understand that my understanding is primitive, but still somehow.

well. If the interest itself can disperse all its 4-8 nuclei to a frequency of 1.2-2.4 GHz, then he will do it ten years.the original frequency is supplied from the quartz, isn't it? if not, then you can then step by step and in words, otherwise I only partly entered the scheme.

and then why some voltages are not enough?

well. if the percent itself can overclock all its 4-8 cores to a frequency of 1.2-2.4 GHz, then it will do this for ten years. the initial frequency is supplied from the quartz, no? you can then step by step and in words, otherwise I only partly entered the scheme. and then why some voltages are not enough?

If only voltages were enough, 10 legs would be enough for the gearbox 😀
There are all sorts of feedbacks from the periphery, self-diagnosis, control, etc. I can't write exactly. If you are interested, you can look for super-detailed service manuals for old Nokias or SE and read how the launch happens. The basic principles remain unchanged.

Why are you so quick-tempered and critical of helping if you want to figure out how the TA is turned on with this type of processor? All the more attached to make it easier to understand. Otherwise, they took the question of “frequency buildup” sarcastically. I never delved into this moment, I really don’t know what to hide a sin, that’s why I asked, but out of good intentions, and you are hostile.
That's right, quartz generates a frequency (I didn’t delve into the manual, but I assume that these are the usual 32.5 kHz, I2C bus) and the diagram is tied specifically to it.

Here is the backbone, and then the devil will break his head here, and even if we now start to smoke all the transient processes implemented in one microcircuit, we will not soon meet the successful solution of the problem))

)) Excuse me if something is wrong. and the truth, I re-read it, it became sickening myself). edited, you can’t convey the intonation written.

in general, you threw me a circuit only for the buildup of the processor and there is no frequency in it. as I understand it, the frequency goes just c quartz. the total power (hence the current consumption is visible on the block) is relatively small, but the power supply of the processor has a very large current.
During inclusion, the percent interviews all nodes, i.e. The periphery, to presence (this by the way, can be viewed during the assembly of the firmware, which modules are interviewed when turning on, and as a rule, the entire periphery is involved there absolutely) hence even more consumption.
As can be seen according to the block, it eats approximately 60-70-90ma on turning on (when the button is clamped), then the step above-280-290-300mas, then 500mas and jumps. And here the periphery is just checked.

HTC Desire 616 Dual SIM does not turn on

Modern smartphones, even with the most careful handling, can fail. More often they arise due to violations in the operation of the operating room, however, mechanical damage can make themselves felt. If the phone does not turn on, then you do not need to rush to contact. Previously, it is worth performing several simple and safe actions that can help reanimate your favorite gadget.

Why is the HTC Desire 616 Dual SIM

There are many reasons for violation of the stable operation of the device – often problems arise against the background of everyday use. According to the masters and representatives of the manufacturers of the devices, the failures when turning on can be associated with the following events:

  • After updating the operating room, any system files were installed with errors;
  • The device stopped loading due to viruses that got with applications installed not from the Play Market;
  • After falling onto the hard surface, the display or battery train disconnected;
  • The USB connector was clogged or small, but harmful spots of rust appeared due to moisture on the contacts.

It is worth noting immediately: to cope with mechanical damage on your own is not easy. During the home repairs, you can involuntarily break any compounds, thereby making the smartphone not a non-combination. If the proposed methods do not give a positive result, then it is recommended to contact a proven SC for diagnosis and repair.

Forced restarting HTC Desire 616 Dual Sim

To begin with, consider several methods related to restoration through the recovery mode. It will be possible to get into it if the gadget is charged by more than 15%. At the same time, by connecting the charger, you can verify the integrity of the screen and the operability of the USB-separation.

So, if the phone responded to connect the charging, displayed the battery replenishment process, then after reaching a suitable level, you can proceed to such manipulations:

  1. Squeeze the power buttons and increase the volume at the same time. Keep them like that until the phone starts to vibrate. The boot screensaver will appear and vibration will follow it, then the power button can be released. Important: sometimes a combination with a volume reduction button is triggered, not an increase.
  2. In the menu that opens, select “Reboot to System” (in some versions – “Reboot System Now”).

The device should immediately go to the reboot, which will follow the standard loading of Android.By the way, if the gadget is not charging, it is recommended to try other USB cables and chargers. It is possible that the problem lies precisely in them, and the phone is simply dead.

Reset to factory settings

After the actions described above, several options for the development of events are possible. In addition to the usual reboot and power on, the phone may turn off again or hang on the splash screen. You should not be too upset because of this, because the manipulations done helped to make sure that a number of important functions and systems are working.

Rebooting through Recovery is an option suitable for situations in which the firmware received minor failures that resolved themselves. If the violation in the operating system is much more serious (for example, after a firmware with errors), then you will have to perform a factory reset. It is important to consider: during such actions, all files, including photos, videos and music, are deleted from the device’s memory.

  1. Open Recovery, as in the instructions discussed above.
  2. Select the item “Wipe data/factory reset”..

The device should go to reboot. It can last much longer than usual (up to 10-15 minutes), after which you will have to perform the initial setup.

Additional Methods

What to do if the methods described above did not help? The gadget suddenly turned off, stopped responding to pressing the power button or charging – with a high probability the problem lies in mechanical damage. If earlier it fell or fell into the water, then it makes sense to contact a service center for diagnostics. Another likely cause is a battery failure. The main symptom is a fast discharge from 100 to 0 percent until a malfunction is detected. For smartphones with removable batteries, you can try to buy a similar one and simply replace it. If the case is solid, then it will not be possible to do without the intervention of the masters.

What to do if your HTC smartphone won't turn on or charge

Once, when I put the gadget on charge, I noticed that my HTC smartphone did not turn on. Moreover, there was no indication that the device was charging. At the same time, the smart did not drop, did not flood, etc. For no apparent reason, it stopped turning on and that's it.

Deeds, I think. And since the prospect of problems with service centers did not particularly attract me, I decided to try to figure it out on my own. Smartphone HTC One M9, operating system Android seventh version. In principle, the quality of HTC's electronics is quite high, but even an old woman can be a mess.

At first I assumed that the problem is still at the software level, and not in the hardware. Therefore, I decided at my own peril and risk to play around with the physical buttons of the device. And you know, friends, the solution to the problem was found empirically.

If your HTC smartphone does not turn on and, like mine, does not respond to the charger, then you can try the following method. But remember that this publication is for informational purposes only and describes my personal experience using a smartphone.

  1. We connect the smartphone to the charger. It is clear that the charging must be original, not fake. In the latter case, the result can be sad.
  2. Simultaneously press the power, volume up and volume down buttons. Only these three buttons, do not touch anything else.
  3. Keep the buttons pressed for a long time. 40-50 seconds was enough for me, but just in case, hold the buttons pressed for 1-2 minutes.

Voila! The smartphone starts to reboot and then works normally. If this does not happen, you can see a menu on the screen, as in the image above. In this case, just press the power button and the smartphone will work.

Please note that the mode must be active. REBOOT, like on a picture. If this is not the case, then you can select it using the volume buttons. As you can see, there is nothing complicated about this. And if after such manipulations your smartphone did not turn on, then most likely you have a problem with the hardware of the device.

In this case, it is better not to experiment and contact a specialized service center. If this method helped you or if you have any questions, write below in the comments!
