طريقة تغيير معالجات كوالكم لأجهزة شاومي

(NOT fused) يجب احضار معالج جديد حصراً

بعدها يجب رفع الذاكرة وعمل فورمات لجميع اللونات

 يمكن تفليش فلاشة مصنعية 

EDL أو ترك الذاكرة فارغة وتفليشها من خلال

تركيب المعالج والذاكرة وتفليش الهاتف والقيام بإصلاح الايمي بالطرق المعروفة

هذه الطريقة تصلح لاغلب المعالجات مثل 

sm7150

sm7250

sm8150

sm8250

الا ان بعض الموديلات تحتاج الى بعض الخطوات الاضافية

POCO X3 PRO هنا معنا مثال على تغيير معالج هاتف 

SM8150 503-AC يحمل معالج

 قمنا برفع الذاكرة من نوع مايكرون وعمل فورمات لها على الميدوسا برو ٢

بعدها قمنا بتركيب المعالج والذاكرة والرام 

 edl وتبويت الهاتف بوضع 

 على واجهة ايزي جيتاج بلس ٢ باستخدام اللودر الموجود داخل الفلاشة المصنعية بدون الحاجة الى حساب مصرح

auth

HW_ID : Qualcomm نلاحظ أن 

fused اما في حال كان المعالج 

HW_ID : Xiaomi ستكون 

نقوم بتفليش الفلاشة المصنعية وسنلاحظ عند اقلاع الجهاز ان البوتلودر مفتوح 

 

bord_id و تبديل مقاومة qcn تم كتابة 

وتفليش فلاشة رسمية

 

اسئلة وأجوبة

لماذا يجب علينا عمل فورمات للذاكرة او ماذا سيحدث اذا تم تركيب المعالج فوراً؟

fused  سيتم عمل 

بشكل جزئي للمعالج ويتحول 

Xiaomi الى HW_ID  

 عند التفليش auth وسيحتاج الى 

ولن يقلع الهاتف بعدها الا على ذاكرة كلين 

 

؟ fused ماذا تعني كلمة

هذه الكلمة لها عدة معاني حسب السياق مثل (منصهر – ملتحم – مغلق )

تقريباً المعنى المراد منها في مجال المعالجات هو مغلق 

 

ماهي الطريقة التي يتم عمل

فيها  للمعالج في المصنع ؟ fused

حسب تجربتي يوجد فلاشة مصنعية من نوع اخرغير المنتشرة عند تفليشها من خلال 

للمعالج مباشرة fused يتم عمل  mi flash

 

هل بمكن تغيير المعالج بدون رفع الذاكرة؟

نظرياً نعم يمكن ذلك من خلال منع الهاتف من رؤية الذاكرة عن طريق لحام سلك بين نقطتين التست بوينت وفصلهم 

 edl عند دخول الهاتف وضع 

وعمل مسح للذاكرة وتفليش الروم المصنعي 

لكن من وجهة نظري الموضوع فيه بعض الخطورة وسعر المعالج مرتفع 

 

ماذا عن باقي الشركات هل يمكن تغير المعالج بنفس الطريقة؟

حسب تجرية بعض الاصدقاء نعم يمكن تغير معالجات لهواتف

ONEPLUS

حتى بدون فورمات للذاكرة او تفليش فقط تركيب المعالج وعمل فورمات من الريكفري واصلاح الايمي

 

 

 

In the name of Allah, the Most Gracious, the Most Merciful.

Method to change Qualcomm CPU for Xiaomi devices:

It is necessary to acquire a new CPU(NOT fused) .

After that, you should proceed to chip-off memory chip and perform a complete format for all partitions.

You can flash the factory firmware.

Or leaving the memory chip empty and flashing it using EDL.

Install the CPU and memory, flash the phone, and then perform IMEI repair using the well-known methods.

This approach is suitable for most CPUs such as:

sm7150

sm7250

sm8150

sm8250

However, some models may require some additional steps.

The POCO X3 PRO serves as an example of changing the CPU of a phone with the SM8150 503-AC CPU.

 

Afterward, we performed a memory chip-off on a Micron memory chip and proceeded to format it using the Medusa Pro 2.

After that, we proceeded to install the processor, memory, and RAM.

We performed EDL boot using the EasyJTAG Plus 2 interface, utilizing the loader present in the factory firmware without the need for an authorized account.

We observe that:

HW_ID: Qualcomm. 

In case the processor is fused we will see :

HW_ID : Xiaomi

We flash the factory firmware, and upon the device’s boot, we will notice that the bootloader is unlocked

Then Write QCN and change board_id resistance

And flashing the official firmware.

Q1: Why is it necessary to format the memory or what happens if the CPU is installed immediately?

Formatting the memory is essential because, if the CPU is fused, it will turn into HW_ID: Xiaomi. When flashing with “auth,” it will require authorized access. After this process, the phone will only boot with a clean memory.

“Fused” has multiple meanings depending on the context, such as “melted,” “fused,” or “closed.” In the context of processors, it generally means “closed” or “locked” by the manufacturer.

Q2: Is it possible to change the CPU without lifting the memory and perform a memory wipe, and then flash the factory ROM in EDL mode?

Theoretically, yes, it can be done by preventing the phone from accessing the memory. This is achieved by soldering a wire between the test points and then disconnecting them when entering the EDL (Emergency Download) mode.

Then, you can perform a memory wipe and flash the factory ROM on the device. However, from my perspective, this process involves some risks, and the cost of the CPU is often high.

Q3: Can the same method be applied to other companies’ phones to change the CPU?

According to some people’s experiences, it is possible to change CPU for phones from other companies like ONEPLUS, even without formatting the memory or flashing. Simply installing the processor, performing a format from recovery, and repairing the IMEI might be sufficient.

Q4: What is the process of fusing the CPU in the factory?

According to my experience, there is another type of less common factory firmware that, when flashed using Mi Flash CPU become fused .
