Four or five years of old mobile phones, even though the hardware is still intact, the more we use the card, the more we use it, the more we use it for half a day, the more we burn the frame when we play the game, the first reaction of many people is that the phone is old. However, a number of recent users of millimetre 11 and millimetre 11 pro have found that the problem may not be hardware at all, but rather that the system is becoming more “thining”。
In the recent past, official mi officially opened the two old flagships to de-escalation of compliance without having to find a third party to brush the kit, without fear of poisoning the bricks, and with official channels to return to the best version of the classic miui. A number of downgraded users have indicated that, after brushing, mobile phones have been able to find a smoother handing back when they were opened, amounting to a free one or two-year extension of old mobile phones. Today we can tell you exactly how it was downgraded, how it was downgraded, what pits were to be avoided, and what friends were suggesting in their hands。
I. How can it be harder to use a flag pole
Let's start with the mi11 series, when it was released in 2021, the first platoon of the achilles. The first batch of 2k-resolution 120hz highscreens, hamancarton double loudspeakers, mi11 pro and 5,000 mah large batteries and 67w fast-filled, were loaded high-end machines in the country, sold on the market, many of them for value。
The time just bought was really good, the system was smooth, the screen was clear and the photo was enough. From the beginning of the second year, a lot of people have been feeling uncomfortable: the system has been updated, the cell phone has been stuck and the fever is getting worse. It was initially thought that the back-office software had been overloaded, deleted, cleared, closed and activated, and had not improved much for half a day. The problem became even more apparent after the upgrade of the os — daily short video is felt hot, half an hour of play is burned and the flight continues to collapse, and the day before it was filled with electricity at noon, and several more aps are often killed backstage。
Why is this happening? The central reason is that, as everyone has heard, the chip, which itself is not well controlled, is called the dragon of fire. When the chip first came out, it did have great performance, but it was also very hot. When the new mobile phone is on the market, the system movement is radical and efficient, but as the use becomes longer, battery ageing and the system is constantly updated to include the new feature, the manufacturer has to tighten the movement of the performance step by step in order to contain the temperature, which, in plain words, is to give the processor a “reduced frequency lock” performance, with the result that the temperature drops a little, but the cell phone is stuck。
Moreover, the newer the system, the more functionality and interfaces, the greater the consumption of hardware resources. New mobile phone handlers are strong, memory large and running; but old flagships four or five years ago, hardware performance is not at the top of the list today, and it's natural to drag on a swollen new system. A lot of people say, "the more the cell phone gets stuck, the more the manufacturer forces you to switch, the less the conspiracy theory, the new system's adaptation to new hardware is industry normal, the old machine is forced to go up, and the probability of experience is compromised."。
Ii. Official downgrading channels open, with two formal routes available select
The most important point of this downgrading was to give older users a “regrets drug” and to be a formal channel for official certification, which is far more secure than a third-party brush kit found online. At present, there are two main approaches, namely, a free downgrading after sale, suitable for small white users, and a self-use of official tools, suitable for users with a certain ability to perform。
It is also the most recommended method for ordinary people to begin with the best down-sale and downgrade。
It's easy to operate without having to prepare anything. Opens the app in millet, finds the “services” page and points the “services centre” to locate the network of authorized services in the vicinity of the house. Before doing so, it would be preferable to make a phone call and make sure that mi11 can be downgraded and that there are no corresponding versions of the solids in order not to go in vain。
When sold, the staff member was told that the downgrading system would normally allow you to sign a risk notice and leave the phone there to brush the machine. The whole process was about an hour, and it was completely free, with no cost. Most importantly, the officially sold brushes use original signature solids, which do not incorporate advertising and viruses, and do not affect the normal maintenance of mobile phones, with zero risk for white。
It should be noted, however, that the downgrading will empty all the data on the cell phone, that photographs, chat records, software will be missing and that important information will have to be backed up before going. It can be backed up with a mic cloud or it can be copied to a computer。
The second is a downgrading of your own line, suitable for a user who likes to dump a cell phone。
This method requires unlocking the bootloader lock on the phone, which is often called the bl lock. Unlocking procedures are not complicated, but there is a waiting period: first, opening the developer option in the cell phone setting, opening oem unlocking and usb debugging, then binding the millet account, going to the millet network to apply for unlocking, downloading official unlocking tools, and usually waiting seven days for cooling. Once unlocked, cell phone data will also be completely emptied, and if unlocked, it may affect some of the main plate maintenance, which should be thought out in advance。
When the lock was unlocked, they went to the official rom download station in xiaomi and found a swipe kit of the same type. Mi11's machine code is vinus, mi11 pro's star, so don't drop the wrong model, or you'll brush it into a brick. The better version is miui 12. 5 stabilization, which is the most balanced flow and temperature control system during the period of the plant, and miui 14, which is the leaner and more fluid than the latest version of the system。
After downloading the solids, the miflash tool, which is official for millet, is installed, the lower volume button and the power button are pressed into fastboot mode under the hand machine, the computer is connected, the brush kit is loaded with tools, the brush is activated by point, and the automatic restart of the mobile phone is completed when the progress strip is completed. The whole process cannot be powered, data lines cannot be drawn, or bricks can easily be painted。
In particular, the so-called unlock degraded “one-key brush tools” on the internet, many of which are modified third-party solids, are hidden in advertising and malicious software, are easily corrupted and have no official warranty. Now that official access has been opened, formal access is of paramount importance。
Iii. What's the experience after the downgrade? We're talking data
With all these methods, it is certain that the most important concern of all is: is it true that after the downgrading, it becomes smooth? Has the continuity and heat improved? I have found two millimetres for more than four years and millimetres for pro, which have tested the actual performance before and after the downscaling to provide an objective reference。
Look at daily fluidity. Upgrading to the latest os millimetre 11, which waits about two seconds to open the micro-letter, sometimes falls from the frame to switch the circle of friends and chat interfaces; when brushing treasures, shivering the sound, the quick-sliding power senses a clear decline in handyness, with three aps on the backstage to reload. After downgrading to miui 12. 5, the most intuitive feeling is that it comes with the hand, with almost all the apps running in seconds, with no drag on the slide interface, with five or six commonly used software in the backstage, and with no frequency of killing the backstage when switching。
With the rabbits running, the whole machine before the downgrade was about 580,000, which could then reach 650,000 below, and the performance was released. Of course, running points is a reference, and the smoothness that is used on a daily basis is the real thing, and many say, “i feel like i've changed a new cell phone”, although a little exaggerated, but promotions are quite obvious。
Let's say we're all interested in heat and continuity. Mi11 pro, 25 degrees room temperature, half an hour short video, approximately 38 degrees on the back of the fuselage, can feel the heat; and half an hour of king's glory, with the paint open, the temperature running straight to 43 degrees, the border is a little hot and the frame rate fluctuates, occasionally falling below 50 frames。
After downgrading to a lean version of the miui 14, a half-hour short video is also painted at a temperature of about 35. 5 degrees, almost a little bit of temperature; and a half-hour of the same game, temperatures are stable at about 39 degrees, and the frame rate is much more stable, largely above 58 frames, without sudden fall of the frame of cardon. This distinction is made because the movement of the old version of the system is more radical and does not allow the chip to operate in a more rational load zone in order to control excessive temperature lock performance。
Improvements are also tangible in the continuation of flights. In the same state of full power, the average daily use before the downgrade is about 20 per cent of the electricity left at night; after the downgrading, the same intensity of use leaves 35 to 40 per cent of the electricity available, equivalent to an additional two or three hours. On the one hand, the backstage of the old system is cleaner and less redundant; on the other hand, the movement is more rational and does not waste electricity on temperature control and backstage activities。
Of course, it's not that demotion is all good. Some of the new features of the old version are less than the latest version, such as the interconnectivity features of partial os, new privacy protections, and some new little system tools. Also, the old version of the security patch is less up-to-date and may be of some concern to users with a special focus on information security. In addition, after the downgrading, the system also plays an updated hint, requiring it to turn off automatically and manually, otherwise it goes back by accident。
Iv. Guides to demoralizing pits. Don't worry about them
It's easy not to look down, but there's a lot of people on the pit. In combination with feedback from many users, several of the most common pits have been sorted out, and it is important for everyone to be careful before downgrading, with fewer curves。
First pit: downgraded without backup data. It was the most important mistake, and i felt that i had nothing to do with it, and it turned out that there was nothing left to cry about. The downgrading is bound to empty all data without exception, even after the official sale. So it takes 10 minutes to back up the demotion, and the turn of the photo, the address book, the chat record, the cloud cover, it's always right。
The second pit: scrambling the kit. A lot of people find a brush kit in a forum or an internet dish, and either the model is not brushed into bricks, or the modified package, which is full of advertising bullet windows, or the presence of malicious plugs, running traffic and leaking privacy. It is important to download the solids from official sources, check the machine code and version numbers, and check the integrity of the documents。
Third pit: too much downgrade. For example, a direct drop from the latest oscillation to miui 12, with several large and android versions, is the most problematic situation, with the possibility of loss of the base belt, failure to open the camera and failure to fill it. If the range is particularly large, it is recommended that the step down be reduced to a transition to an intermediate version and then to a target version, which is much more secure。
Fourth pit: brusher breaker. When you brush your own wire, it is important to ensure that the computer has enough power, that your mobile phone has enough power, that you will never pull out the data line during the brush, or that you will not be able to reset your cell phone by force, or that it will be easy to paint “bricks” and then sell the bricks, which is more troublesome。
The fifth pit: thought that demotion would solve all the problems. If your cell phone has been in operation for four or five years, and the battery's in poor health, for example, has fallen to less than 80 percent, it's limited to a downgrading to improve continuity. This situation suggests that the combination of a battery and a downgrading system would be the best. Official mi also now has old-style battery replacements, which are not expensive, and it is obvious that after the re-routing, the upgrades were made。
Whether to downgrade or not? These categories suggest it
In conclusion, who is fit to downgrade, and who is not recommended。
The first category recommended for downgrading is the daily use of users who feel like carden, who have a fever, and whose mobile phones are mainly used to brush videos, talk about tweets, and play ordinary hand games. For you, the functionality of those flairs in the new system is largely inoperable, and it's very cost-effective to experience a straight step after the downgrading and re-routing。
The second group is intended to use mobile phones as backups or for the elderly. The older generation does not need much functionality to use their mobile phones, and stability, fluidity and power efficiency are of paramount importance. They are down to the classic stabilization system, with fewer advertisements, simpler operations, and older generations using them, and one year or two。
The third category is users who like to play games and toss systems, and after the official opening of the channel, they do not have to take the risk of finding third-party solids, and the official version of the system is reassuring and can experience variations in different versions and be more fun。
What kind of guy wouldn't recommend demotion
The first is the regular use of mobile phones to work and process sensitive information, with particular emphasis on data security users. The security patches of the old version of the system were not updated in a timely manner, were less protective than the latest version of the system, and the safety of the flow was sacrificed to such users。
Second, users relying on the functions of the new system, such as frequent eco-connection with millimetres, multi-equipment synergetics, or privacy protection with new versions of the system, intelligence functions, which may not be used after downgrading, but may affect daily use。
The third category, which is totally digital, has a poor ability to do things and has no friends around who can help. While down-sale downgrades are simple, it would be more prudent if the backup data were not even clear. I really think it's a lot easier to try to restore the plant。
On the whole, it was a good conscience to open the official downgrade to the old flagship. Now that many manufacturers are forcing users to upgrade the system, the older the model becomes more difficult to use, and eventually it can be replaced. It is true that mi is willing to give old users an opportunity to choose systems according to their needs rather than being forced to upgrade。
If your mobile phone hardware is okay, it's just a system card, it's hot, you can really try to downgrade it, and you don't have to spend thousands of dollars on a cell phone, you can get back to good use. Of course, it's best to remember to back up the data before downgrading, to go through official channels, not to mess with third-party bags, and to give old mobile phones a proper “severe life”。
This paper is for personal use experience sharing only, and all test data are derived from individual measurements, and the actual effects of the downgrading may vary depending on the length of use, loss of hardware and different usage habits. There is a risk that the system will be downgraded, and it is recommended that the personal data be backed up in advance and that the equipment problems caused by the self-wiring machine be handled through official formal channels。
