Analysis of newer Sony Ericsson models
Models such as w200, k510i, k310, k320, which allow sending SMS messages, are disassembled as follows:
When disassembling the phone, you should remember, write down or photograph the order of removing parts and some complex nuances. Because, as you know, it is always much easier to disassemble a device than to assemble it.
The materials of this article are aimed at novice mobile phone repair specialists. The information presented allows you to get a general idea of ​​the structure, methods of restoring software (software) and the necessary software tools intended for SONY ERICSSON (hereinafter - SE) mobile phones manufactured in 2004-2011. The first part of the article will outline the basic theoretical information required to perform work with phone software.
The history of SONY ERICSSON ended at the end of 2011, when SONY acquired its share in the joint venture from ERICSSON. Currently, the phones of this manufacturer come out exclusively under the SONY trademark, and the company itself has focused on the release of smartphones running the Android operating system (OS). Nevertheless, users still have a lot of phones, released by the company during its heyday (2004-2007) and later. At the same time, due to high-quality displays and cameras, as well as convenient software (including support for JAVA applications on older models), successful phone models from SE (for example, K790, W580 and others) remain for their owners to this day. relevant.
SE mobile phones use three types of interface connectors - proprietary (Proprietary - owned by someone, not shared. The word is formed by transliteration of the English term proprietary. There are proprietary software, protocol, format ) 11- and 12-pin (see tables 1 and 2), as well as standard microUSB. At the same time, all relatively modern phones from this manufacturer are equipped with either a 12-pin connector or microUSB. It should be noted that the 12-pin SE connector also has a standard USB interface (pin 1 - USB 5V, 9 - GND, 10 - USB DATA +, 11 - USB DATA-), so the differences in software repair phones with 12-pin and microUSB-connectors are only in the type of cable used. The 11-pin connector does not support the USB interface, it only supports operation via the COM port or cables with a USB / COM converter (Prolific PL2303 and others).

Note. The phone recognizes the connected accessory as a headset Hand – Free (that is, the headset microphone is used during a conversation) with a resistance between 8 and 9 contacts of 170 Ohm, and with a resistance between these contacts of 820 Ohm, the phone recognizes the accessory as headphones / speakers (that is, the phone microphone is used during a conversation)
When working with the SONY ERICSSON phone software, the following common terminology is used:
CID - SE phone software protection against unauthorized access: saving a copy of the phone software, reprogramming it or unlocking third-party software. CIDs are also used to protect OTP and EROM areas. For direct work with CID phones, the proprietary EMMA software is used - used in authorized service centers SONY ERICSSON. A smart card is used to protect it from unauthorized distribution and use.
CDA - an identifier used to determine the main parameters of the phone: brand, language package and blocking the device for a specific mobile operator.
OTP (one-time-programmable) - a memory area intended for one-time programming. In SE phones, OTP is used to store IMEI and CID, while the CID stored in the OTP may be a younger version than
EROM - Expanded ROM: An area of ​​memory used to store the system settings of the phone. EROM also contains a boot loader that allows the system to control the remote software update interface. If the EROM is damaged, the phone will not work, and when you try to turn it on, it only blinks with an interface lamp, usually located in the area of ​​the infrared port. When restoring the EROM of a phone, it is not allowed to download data from other models or from phones of the same model, but with a different CID.
Phone “color” - BLUE, BROWN, RED: defines the purpose of a particular phone. The “color” of the phone is stored in the EROM. RED phones are intended for sale to end consumers, BROWN are technology phones designed for testing and debugging software, BLUE is an empty board assembled at the factory, but never sold.
Gdfs - an area of ​​the phone's memory where settings and calibration data are stored, including IMEI and operator lock parameters. In SE phones, the IMEI is stored in two memory areas - in the OTP and in the GDFS. SE phones use NVRAM (Non-Volatile Random Access Memory) to store GDFS. If the IMEI values ​​in GDFS and OTP are different, the phone will not turn on.
DBŃ…Ń…Ń…Ń… - designation of the hardware platform of the device.
SIM-LOCK - blocking the phone for a specific mobile operator. Unlike other manufacturers, SE phones store lock settings in NVRAM. The presence of blocking for a specific operator is also reflected in the phone's CDA. If you insert a SIM card of another mobile operator into such a phone, the message "Insert correct SIM" will be displayed on the phone screen
USER-LOCK - phone code set by the user.
According to hardware and software components, relatively modern SONY ERICSSON phones are divided into two families - A100 (A1) and A200 (A2), and within families - by platforms, denoted by an alphanumeric code. A100 family includes hardware platforms DB2000, DB2010, DB2011, DB2012, DB2020, and A200 family includes DB3150, DB3200, DB3210. Older models belong to ARM, AVR, CR 16B platforms, as well as a number of ODM platforms. See Table 3 for hardware platform details for some of the popular models.

Phone disassembly video
VIDEO
Hi all!:-)
Hello. Such a moment. I dug up my old K790, decided to restore it ... I started to disassemble it today, and when I removed the back cover with the shutter, 2 parts fell out (one the size of a crumb, white, looks like a “whirligig”, and the second is a spring). Without them, the shutter "flies" back and forth, not fixed.
Hey! If I'm not mistaken, in the second photo you can see where the spring is placed near the lid, you need to try, I can't say there.
I tore out my eye, but did not consider it) well, in the evening I will try to trick))) ATP
The upper left corner (if you look at the circle of the camera) seems to be where the spring is sparkling 🙂
I see, And such another question, perhaps you remember from old memory ... When to remove that part of the case, should the lens cover be “closed” or “open”? When I was filming, it was closed.
closed, then sign off what happened.
closed, then sign off what happened.
It turned out to be assembled yesterday.))
You are engaged in bourgeoisie) k790 has already become a spare, and my main one is still Nokia 3310, though it is stitched.
4 years have passed, the phone is still working 🙂
I changed 2 more firmware, and began to use it a little less often, because it's a pity) But it's still the same)
Damn I have the same stolen ... Damn I want the same now!
There should be a ride to Gorbushka)
I also have an excellent k800 device
🙂
he took pictures on the main page by the way he was brought from germany and the sticker above the joystick is not a cybor shot but it is written VODAFONE
Today I will talk about how to repair a cell phone myself. SonyEricsson Z520i ... This phone fell into my hands by accident, one girl I knew said that her phone had broken, which served her faithfully for 4 years, in the workshop they told her that the video processor had to be changed and called such an amount that it would be easier to buy the same and more and a lot of money will remain. And so I was offered to look at it, well, of course, I agreed.
I’ll say why right away, I decided to start repairing the Sony Ericsson clamshell. True, my Sony Ericsson phone is not a clamshell, but the quality, durability and functional set of this phone pleases me for the fifth year already. If we talk about a specific phone model SonyEricsson Z520i, then of course its functionality is simpler than that of my SonyEricsson K770i, but the model is quite attractive, functional and not too expensive. Typical design for SonyEricsson, the best traditions of quality and low prevalence in our market (not to be confused with popularity and success) make Z520i a worthy mobile travel companion.
- attractive design, it is possible to change the design by replacing the body elements
- good performance in sound and communication
- battery charge lasts from 4 to 6 days
In general, we can say more positively about SonyEricsson Z520i than vice versa. Based on all this, it was decided to save the life of the apparatus.
And so the first thing I did was to recharge the phone's battery, since it was out of operation for a long time. After the battery was charged, I installed the SIM card and turned on the phone. The phone started up, but there was no image on the displays, although they were backlit. After that I tried to call him. The phone worked. The conclusion that could be made is that the train is most likely worn out or broken.
After I decided what the problem was, I decided to check it out.
He turned off the phone, removed the battery cover and took out the battery. I took off my SIM card. I took a special curly screwdriver and unscrewed 4 screws in the part of the case where the battery was located and removed it. Having experimented a little with the break in the train, I saw a running image on the screen. The assumptions were confirmed, the train was broken, and the rest everything is functioning normally.
I went to the nearest cell phone repair shop and asked if there was a SonyEricsson Z520i cable. The train was available and it cost 450 rubles. I also bought super glue. For repairs, you will also need a small piece of thin and flexible plastic. That's all that was needed to repair the phone. Now I will tell you, in a photo-report, how to independently repair a SonyEricsson Z520i phone from start to finish.
The Sony Ericsson Xperia Arc S LT18 smartphone was accidentally found while vacationing at the sea. We pry off the back cover from below, then unscrew the six screws. I snap off the case near the headphone jack. Prying off the HDMI connector flap, I snap off the case in this place too.
We fold back the back panel and see a sad picture - sea water got through the battery connector and the SIM card connector inside. The chemical salt reaction was not long in coming, and the electrolysis process was in full swing. It's amazing how quickly rust stains form on metal. In some places, for example under the insulating sticker, water could not flow due to the presence of a layer of surface tension. There is relatively little rust under the metal screen. In some places on the motherboard there are microcircuits filled with compound along with their strapping - this can be used by anyone - no water got here.
Diagnosis: the display and the board are corpses, the speakers are half-dead, the camera seems to be normal, the body of the mobile phone is in relatively good condition. Some mikruhi from the system stalemate can be used as a donor for repairs.
In accordance with the algorithm in the service manual, carefully disassemble the mobile phone and take out the motherboard on which the joystick is soldered. Due to the fact that radioelements sensitive to overheating are located next to the broken element, it is not recommended to dismantle the joystick with a soldering iron, but it is better to use a special hairdryer for this.We set the temperature on it to 250 degrees, but not more, and warm up the joystick contacts, as soon as the solder begins to melt with tweezers, we take out the old joystick, and then, after cleaning the contact pads, for example with a copper braid, we solder a new one.
Replacing the touchscreen with the Sony Ericsson WT19i is quite simple. For this, a special "thanks" to the developers of this phone should be said, because the disassembly-assembly process is quite simple due to its design features. In principle, no special difficulties should arise in the process - you just need to be extremely careful and not lose the screws, which will be a lot during the dismantling process.
So, to the point. Sony Ericsson WT19i disassembly begins with removing the rear protective cover. It is fastened with latches. There is nothing new in this step, since you already had to remove it, maybe more than once to install a SIM card.
We take out the SIM card, memory card (if available) and the battery. To disassemble the Sony Ericsson WT19i further, you will have to unscrew 9 screws, 5 of which can be unscrewed with a Phillips screwdriver, and 4 with an asterisk.
... and gluing a new one.

Consider a mobile phone repair Sony Ericsson T700 with a constantly displayed connection mode in the car.The device was already under repair, but the qualifications of the craftsmen were not enough to understand the malfunction.
Again I begin to describe the repair after the "masters". Came to me, this time not turning on Sony Ericsson X10i , which did not react to the power button in any way.
So all the holidays have passed and working days have begun again. The first entry this year will be dedicated to the repair of a mobile phone Sony Ericsson K850i with a rather common malfunction for it - it does not turn on.
Today I want to share my experience in repairing a mobile phone that does not turn on. Sony Ericsson C905 ... Symptoms are very hazy, when you press the power button, consumption 20 mA and nothing more. When connected to a computer, nothing happens, no reaction, not a combination of buttons “C ”And connection USB no cord with buttons "2+5 ”.
Another phone repair Sony Ericsson W205 , it is not very often necessary to repair them due to the difficulties with finding spare parts. This time the malfunction was in the missing backlight of the display and keypad, the phone had already been disassembled in some workshop and the loop was changed, it is not clear why ...
A fairly common malfunction of the Sony Ericsson S500i / W580 is a faulty microphone. But there may be several reasons for such a breakdown.
Video (click to play).
I had to repair a lot of phones of this brand. Due to its low cost and rather wide range of functions, it quickly gained popularity. As a rule, teenagers use this model, and this is a frequent change of SIM cards, constant falls and mechanical stress and many other factors leading to its breakdown. True, besides everything they have their own factory flaws, which appear after the expiration of the warranty period.
