طريقة فك OTP تعتمد على بعض تفاصيل الذاكرة
عندما يكون الهاتف يحمل معالج اكسنوس ويحمل ذاكرة UFS 3.0 , UFS 3.1 BGA153 انتبه لحجم قطاع LUN4
اذا كان حجمه 16 ميقا بايت او 20 ميقا بايت هنا عليك فقط بتوصيل isp وكتابة ملف sboot من فلاشة كومبنيشن وبعدها افصل الاسلاك وادخل الهاتف وضع داونلود وهكذا يتم فك otp ويتحول Re config إلى Enabled
اذا كان حجمه 8 ميقا بايت هنا تحتاج إلى رفع الذاكرة ثم وضعها على اي هاتف سامسونج اخر حجمه 16 او 20 ميقا بايت وكتابة sboot +ldfw+tzsw من فلاشة كومبنيشن وبعد ادخال الهاتف وضع داونلود يتم فك otp ويتحول Re config إلى Enabled وبعدها يمكنك ارجاع الذاكرة إلى هاتفها
وهذا مثال عن هاتف E625F
The way to Unlock OTP depends on some memory details
When the phone has an Exynos processor and has UFS 3.0, UFS 3.1 BGA153 memory, pay attention to the LUN4 sector size.
If its size is 16 MB or 20 MB here, you just have to connect the isp and write the sboot file from the flash combination, then disconnect the wires and enter the phone in download mode, and you will see that the reconfiguration has been Enable (OTP Not Locked)
If its size is 8 megabytes here you need to chip-off the memory and then put it on any other Samsung phone of 16 or 20 megabytes and write sboot +ldfw+tzsw from the combination flash and after entering the phone download mode and will see that the reconfiguration has been Enable (OTP Not Locked) and then you can return the memory to its phone
This is an example of the E625F
اما اذا كان الهاتف يحمل معالج اكسنوس ويحمل ذاكرة BGA153 UFS 2.1 هذه سنخصص لها مقال منفصل
اما اذا كان الهاتف يحمل معالج كوالكم ويحمل ذاكرة BGA254 UFS 2.1 , UFS 2.2 هنا عليك برفع الذاكرة وتركيبها على هاتف سامسونج A33 او A53 ولكن هذة الهواتف لا تقلع اذا كتبت sboot فقط او كتبت bl من فلاشة عادية لذلك يجب كتابة دامب سليم وبعد ادخال الهاتف وضع داونلود وهكذا يتم فك otp ويتحول Re config إلى Enabled وبعدها يمكنك ارجاع الذاكرة إلي هاتفها
اما في حالة كان الهاتف يحمل معالج كوالكم ويحمل ذاكرة BGA153 UFS 3.0 , UFS 3.1 عليك برفع الذاكرة وتركيبها على اي هاتف اخر يحمل معالج اكسنوس شرط ان يكون حجم قطاع lun4 هو 16 , 20 ميقا بايت
ملحوظة مهمة جدا (تحذير)
قبل فك OTP لهواتف كوالكم او اكسينوس(LUN 4 8MB)
يجب عليك سحب discreptor وايضا تسحب ملف attribute
باستخدام MiPitester حصراً في الوقت الحالي
(ميدوسا برو٢ ينجح بسحب الملف لكن يفشل بالكتابه)
ملف discreptor مسؤول عن قطاعات الذاكرة
وملف attribute مسؤول عن ضبط REF_CLK
عندما تقوم بفك otp ستجد ان التردد اصبح 24MHZ و الضبط المظبوط للتردد هو 19MHZ لذلك تحتاج إلى هذا الملف في حال الهاتف كوالكم
وهذا هو الحل لمشكلة موت الهاتف بعد فك otp في حال الهاتف كوالكم
But if the phone carries an Exynos processor and carries this BGA153 UFS 2.1 memory, we will devote a separate article to it.
But if the phone has a Qualcomm processor and BGA254 UFS 2.1, UFS 2.2 memory, here you have to chip-off the memory and install it on the Samsung A33 or A53 phone, but these phones do not boot if you write sboot only or write bl from a regular flash, so you must write a full dump and after inserting the phone into Download mode and will see that the reconfiguration has been Enable (OTP Not Locked) and then you can return the memory to her phone.
In the event that the phone has a Qualcomm processor and has BGA153 UFS 3.0 and UFS 3.1 memory, you have to remove the memory and install it on any other phone with an Exynos processor, provided that the size of the lun4 sector is 16.20 MB.
A very important note (warning)
Before unlocking OTP for Qualcomm or Exynos phones (LUN 4 8MB)
You have to pull out the discreptor and also pull out the attribute
Exclusively using MiPi tester at the moment
(Medusa Pro 2 succeeds in reading the file, but fails in writing)
The file discreptor is responsible for memory sectors
The attribute file is responsible for setting REF_CLK
When you unlock the otp, you will find that the frequency has become 24MHZ, and the right setting for the frequency is 19MHZ, so you need this file. If the phone is Qualcomm
This is the solution to the problem of the death of the phone after decoding the otp in the case of the phone as Qualcomm
وايضا هو الحل لمشكلة UFS provision fail عند تغيير الذاكرة لهواتف اكسينوس (LUN 4 8MB)
وايضا هو الحل لمشكلة UFS provision fail عند تغيير الذاكرة لهواتف اكسينوس (LUN 4 8MB)It is also the solution to the UFS provision fail problem when changing the memory for Exynos phones (LUN 4 8MB)
