Problem description
How to fix an iPhone 7 or 7 Plus that is bootlooping. When flashing an update or restore, it fails with Error 9
Symptoms
- Bootlooping
- Flashes Apple Logo on and off
- Fails to restore
- Error 9 on iTunes
- Stuck in Recovery Mode
Solution
You'll want to check these first to confirm you have a board issue:
- Get a known good screen, charging port and battery -- Helps validate that you have a board issue.
- Get a known good OEM iPhone cable
- Flash with 3uTools using Easy Flash
- Flash with 3uTools using iTunes Flash
If 3uTools Easy Flash gives you a failure at 19% or 20% and 3u Tools iTunes Flash gives you Error 9, then the issue is NAND. You'll need to replace NAND. NAND is the memory/storage chip.
Compatible NANDs
For iPhone 7 and 7 Plus, you can use the NAND of any of the following devices interchangeably:
- iPhone 6S
- iPhone 6S Plus
- iPhone SE (1st Gen)
- iPad Pro 9.7
- iPad Pro 10.5
- iPad Pro 12.9 Gen 1
- iPad Pro 12.9 Gen 2
- iPad 5th Gen
- iPad 6th Gen
- iPad 7th Gen
NAND Programming Process
Requirements
In order to successfully replace the NAND, you'll need the following from the original device or NAND and write it to the replacement NAND, otherwise it won't activate.
- SN (Serial Number)
- WiFi Mac Address
- BT (Bluetooth) Mac Address
It's also recommended you set these to the correct values, but technically will function fine if you put different values
- Region (USA, China, Japan, UK, etc.)
- LL/A is for USA
- Color (Black, White, Rose Gold, Red, etc.)
- This sets the boot up color of the screen. iPhones with a white screen will boot with a white background and black Apple Logo and vice versa for black screen devices.
Tools
You can use any NAND programmer that supports iPhone 7/7P.
JC P7 seems to be the most popular.
iRepair P10 is another option, that does NAND programming via the lightning port and uses the available "Purple Mode" exploit.
What if I don't have the original NAND data?
You can get the required NAND info from above, by reading the original NAND from the device.
In most cases, you should be able to read the NAND data.
If it can't, you'll need to find it elsewhere
- GSX report (You'll need to find someone who offers this service)
- MagicCFG Recovery (requires Jailbreak)
- Use JCID Drawing + JC P7
Sometimes, the GSX report service is not available.
Using MagicCFG Recovery
First, you'll need to install the replacement NAND, with any generic data filled in for SN, WiFi, BT, etc..
Then restore the phone
Then you need to jailbreak the device with Checkra1n
After, run the MagicCFG Recovery tool, which will capture the SN, WiFi/BT Mac addresses.
Then go back, read the NAND, edit the SN, WiFi, BT addresses and write them again into the NAND
Then restore one more time
Now you should be able to activate the device.
Use JCID Drawing + JC P7
Install a new NAND on the phone with a generic SYSCFG data. The exact values don't matter.
Then restore it
Then pull the NAND and put it back into JC P7 and use JC Drawing software to query the factory code
Then program the SN, WiFi, BT values into the NAND
Reinstall NAND & restore.
It should activate now.
