to repair using Borneo scripts?
Operational case: Oppo A5S repair - malfunction power breaker with multiple shorts

ـــــــــــــــــــ____ــــــــ

📱 Device information:
- Brand : Oppo
- Model : A5S
- Outage: Power Interruption (No Power)
- Background: A device that was previously tried to be repaired by another artist
- Source : Richie Riyandie

ـــــــــــــــــــ____ــــــــ

🔍 Initial examination and condition:
- Appearance: IC power is properly mounted but area is full of vix and damp indicating multiple previous repair attempts

- Note: The Charging IC also appears to have been Reassembled or replaced in advance.

- Initial conclusion: Multiple malfunctions are likely resulting from previous failed repair attempts.

ـــــــــــــــــــ____ــــــــ

🔧 Detailed repair steps:

Step 1: Initial diagnosis using schemes (Borneo Schematic)

1. Back to diagram: opening the device diagram (borhardsho a5s) to understand the main input and output circles

2. First check: VSYS (main voltage system) line resistance measurement in non-feed (Pasif).

3. Result: Discovered the presence of Short on the VSYS line ❌. This stops the device from running completely.

Step 2: identify the source of the first shorts (on VSYS)
1. Limited voltage (injection): Using power supply and low voltage injection (4.1V) on VSYS line with low current detection.

2. Note: Charging IC got very hot quickly

3. Procedure: remove the charging IC.

4. Check: measuring VSYS line resistance again. Value returned to normal ✅. First shorts problem solved

Step 3: In-depth diagnosis and discover second shorts

1. Power Circuit Inspection (PMU): After removing the charging IC, the power management circuit was thoroughly examined.

2. Measurement : VEFUSE_PMU line resistance measurement

3. Result: Short detected on VEFUSE_PMU ❌ line.

4. Track Tracing: Using a Bitmap of a diagram, the VEFUSE_PMU track was tracked and found to be connected to the Power IC and CPU.

Step 4: isolate the source of the second shorts

1. Initial procedure: remove the resistance (VEFUSE_PMU) itself

2. Size: shorts are still available ❌. This means that failure is not in resistance itself but in one of the components connected to it

3. Next action: remove the power IC

4. Result: shorts are gone completely ✅. IC power has been identified as source of second shorts

Step 5: repair and final installation
1. Preparing IC: Repolling work for everyone:
*IC NEW SHIPMENT
*IC the new power
2. Installation of IC: Installation of charging IC and power IC accurately on the board.

3. Final check: Measuring all critical lines (VSYS, VEFUSE_PMU) to ensure that any shorts are gone ✅

4. Reassembly: Resistance Welding (VEFUSE_PMU) in place

5. Test: Connect the battery and press the power button

The device has been successfully activated ✅

ـــــــــــــــــــ____ــــــــ

🎯 The lessons learned from this situation:

1. The "Failed Previous Reforms" challenge:
- A vortex-filled and humidity indicates a disorganized handling and may hide multiple glitches.

- of a good cleaning first before starting a new diagnosis.

2. Methodology of dealing with multiple shorts:

- Removing one ingredient is not enough. Mainline shorts (like VSYS) might be temporarily resolved but all circuits should be checked afterwards.

- Tracking the path using a Bitmap is necessary to accurately isolate the responsible component between several possibilities (such as PMU or CPU)

3. The importance of a sequence of reform:
- Starting from the power input towards the heart: first the charging IC (responsible for VSYS) then the power IC (responsible of VEFUSE_PMU)

- Repairing in stages and checking after each step prevents failure

4. The Interpretation of Circles:
- VSYS : is the main voltage that feeds most of the device's circuits after the battery.

- VEFUSE_PMU: is a valve-resistance protected line (Fuse) that feeds the same power IC or sensitive circuits from it

Having shorts on is a direct threat to the power IC or the processor

ـــــــــــــــــــ____ــــــــ

💡 Practical tips for technicians in complex shorts cases:

A roadmap for a completely complex water diagnosis:
1. Cleaned up the panel well of debris from previous repair.
2. Search Energy Path Shorts: Measure:
* VBAT / VSYS → If short, look for heat around charging IC, condensors, power IC.

*VEFUSE line or other PMU lines → if short focus on IC power and processor.

3. Use the injection method (Voltage Injection) carefully: Start with a very low voltage (1-2 volts) and limited current (1 amp or less) to avoid the loss of healthy components.

4. Isolate the main components one after another: (charging IC → power IC → in some cases files).

How to handle CPU damage suspicions:
- Cooling IC power did not solve the problem: the next step will be difficult and it may indicate shorts inside the processor itself.

- In this case: the shorts came from the damaged charging IC and damaged the power IC, but it did not reach the processor, which saved the device.

ـــــــــــــــــــ____ــــــــ

⚠️ Reasons for previous reforms to fail in this case:
1. Incomplete diagnosis: Perhaps the previous technician discovered the charging IC problem and reinstalled it or replaced it, but he did not examine the internal power circuits (such as VEFUSE_PMU) afterwards.

2. Wrong sequence: power IC may have been changed first without fixing VSYS shorts resulting from charging IC resulting in damage to new IC

3. Neglect clean-up: Vix waste can cause electrical leakage or shortage between micro-paths.

ـــــــــــــــــــ____ــــــــ

🛠 Tools and materials that made the difference:
1. Borneo Schematic, especially the Bitmap function for tracking the tracks.
2. DC Power Supply for injection and thermal detection.
3. Thermal or elastic camera to detect the hot ingredient.
4. Precision Hot Air for multiple slide removal and installation.

ـــــــــــــــــــ____ــــــــ

📞 In conclusion :
This case is an advanced example of Domino Effect failure repair.
Important lesson: A previously repaired power breaker needs a deeper, comprehensive examination.
Don't stop at the first break you find, there might be a second break waiting for you. Patience, methodology, and using the plans to deepen your track tracking are the secrets of success

Apple wameongeza simu toleo la iPhone X kwenye idadi ya bidhaa ambazo zinakaribia kukosa huduma ya maboresho kutoka katika maduka yao maalumu ya matengenezo.

Hii ina maana, kuanzia sasa utaweza kutengeneza simu yako katika maduka yao maalumu lakini kutokana na uwepo wa spea utazozipata, na k**a utakosa basi huenda ndio ikawa mwisho wa simu yako sababu Apple hawazalishi tena vitu vyovyote vipya kuhusu toleo hilo.

Baada ya miaka 02 kuanzia sasa wataacha kupokea kabisa simu hizo kwaajili ya matengenezo. Vifaa vingine vilivyo ongezwa ni spika janja za HomePod (2020) pamoja na Airpods (2016).
