Aisi Assistant flashing error code list: 4013/4014/53/-1 How to solve it
If you get an error after flashing, don’t go crazy and try again. The vast majority of errors can be solved by following a fixed sequence - this article will give you a general troubleshooting process + a quick checklist of common error codes and detailed explanations of key codes.
1. General troubleshooting sequence (90% of errors are reported in this sequence first)
No matter what code is reported, first eliminate them one by one in the following order - many people spend a long time fiddling with it, but in fact, it is just a matter of replacing the original cable and plugging it into the correct USB port.
2. Error Code Cheat Sheet
| error code | Common meanings | what to do |
|---|---|---|
| 9 | Hard drive not reading/power supply problem | Change the computer, check the power supply of the hard disk, and refresh it several times. |
| 11 | Insufficient space on C drive | Clear system disk space and then refresh |
| 14 | Insufficient power supply/USB abnormality | Replace the original cable, replace the rear USB port, and brush it several times. |
| 40 / 4013 / 4014 | Hardware communication (data cable/hard disk/CPU virtual soldering/I2C) | Original MFi cable + rear USB2.0, turn off the firewall, repair the driver, change the computer; 60% multiple hard drives, 80% rear multiple baseband/power supply |
| 53 | Touch ID / face module or cable | Refresh the mobile hotspot network; the module is damaged and requires hardware repair |
| 3004 | Server refused connection/Authentication is turned off | Confirm that it is still in the signing period, check hosts/agent, and upgrade to a new version of the client. |
| 3194 | Apple has stopped signing this firmware (downgraded) | The old version cannot be restored; choose the version that is still signed. |
| 26 | Verification just closed | Refresh signature status and confirm again |
| -1 | Baseband communication failed | Most of them are hardware, check them in order and then send them for repair. |
| -50 | Server communication timeout | Check the network/proxy, update the client, and try again during off-peak hours |
| 35 / 37 / 38 / 41 / 47 / 48 | Hard drive failure | Mostly due to hardware problems, it is recommended to check/send for repair |
3. Detailed explanation of key error codes
4013 / 4014 (highest frequency)
The essence isHardware communication between the device and the computer is interrupted. Let’s start with the cheapest: original MFi data cable, hostRear USB2.0port, avoid the USB Hub; turn off the firewall and anti-virus, repair the driver, and change the computer. if alwaysStuck at a fixed progress: 60% nearby andharddiskRelated, more related to after 80%Baseband/Power supplyRelevant, this type of problem will most likely require hardware repair.
53 (face/fingerprint)
Mostly related to Touch ID/Face ID module or cable. Use mobile phone firsthotspot networkingTry reflashing; if the module itself is damaged, software flashing cannot save it and requires professional repair.
3194 / 3004 (exclusive for downgrade)
These two almost appear inDowngradeScene: 3194 = AppleSigning has been stoppedThis firmware cannot be flashed back to the old version; 3004 = Server connection refused/Authentication is turned off. First use "Query SHSH" to confirm whether the target version is still in the signing period. If necessary, check the hosts/agent and change to the latest version of the Aisi client.
-1 / -50
-1 is oftenBaseband communication failed(probably hardware); -50 mostlyServer timeout, it is a network/proxy problem, just change to a new version of the client and try again at the wrong time.
4. Still not working? These are the signs that it’s time to have it repaired
- After changing lines, ports, and computers4013/4014 Still stuck at the same progress——Mostly caused by hard disk/baseband hardware problems.
- recurring-1Or hard disk failure type (35/37/38/41/47/48) - the probability at the hardware level is high.
- AisiUnable to read machine inspection information/Invalid serial number——The device may have been deeply modified or the motherboard may have an underlying problem.
FAQ
How to solve the AIS flash error 4013/4014?
Mostly caused by hardware communication issues. Replaced the original MFi cable + rear USB2.0 (avoiding Hub), turned off the firewall and anti-virus, repaired the driver, and changed the computer; 60% of the hard drives and 80% of the rear basebands were stuck, and repeated failures were sent for repair.
Can I fix AISI error 53?
Mostly related to the face/fingerprint module or cable arrangement. First connect to the hotspot and re-flash; the module is damaged and requires hardware repair, but software cannot solve it.
What should I do if I get an error message halfway through brushing?
Don't force the connection, don't be crazy and try again. First "exit recovery mode" and boot normally, then troubleshoot according to the general order and then re-flash; the downgrade may be that the signature has been turned off and cannot be re-flashed.
What is 3194 / 3004?
Common when downgrading: 3194=Apple has stopped signing the firmware and cannot flash it back; 3004=The server refuses to connect/verification is turned off. Select the version that is still signing, check hosts/agent, and change to a newer version of the client.
What is -1 / -50?
-1 is mostly due to baseband communication failure (possible hardware); -50 is server timeout, check the network/agent, change to a newer version and try again at staggered peaks.
Why does it show that it can be refreshed but fails?
"Flashable" only means that the firmware is signed; whether it can be flashed depends on the compatibility of the data cable/USB/driver/hardware and system, and is excluded one by one in a general order.
