iPhone panic reports
Find out which part makes an iPhone restart. The report is read on this computer and never uploaded. Free, no credits used.
How to get the report from the iPhone
On the iPhone: Settings › Privacy & Security › Analytics & Improvements › Analytics Data. Open the newest panic-full-… file, tap Share and send it to this computer (AirDrop, WhatsApp to yourself, email), or copy all the text and paste it above.
Windows: sync the iPhone once with Apple Devices or iTunes, then open %APPDATA%\Apple Computer\Logs\CrashReporter\MobileDevice\<iPhone name>.
Mac: sync once in Finder, then open ~/Library/Logs/CrashReporter/MobileDevice/<iPhone name>.
No panic-full file? The phone has not restarted from a fault since the list was last cleared.
Reading the reports straight from the phone needs the iPhone to trust the computer through Apple's own tools, which a web page cannot do.
Android crashes and restarts
Why an Android phone restarts, freezes or closes apps, and which part to check. Read from the phone over USB debugging (the owner taps Allow), or paste a bug report or log. Read on this computer, never uploaded. Free.
Settings › Developer options › USB debugging on, then plug in.
Fault finder
Pick the phone and the symptom, answer a few checks, and get the likely part and the fix — with the phone's own readings, what fixed it before at your shop, and the AI if you need more. Free.

Connect a phone in three steps
0016 reads information exposed by your device’s Fastboot interface. The available details depend on the manufacturer and model.
01
Start in Fastboot
Power off your Android phone and enter Fastboot / bootloader mode using the manufacturer’s key combination. The exact steps vary by device.
02
Make the connection
Open this workspace in Chrome or Edge on a computer. Connect your phone using a data-capable USB cable. A charging-only cable won’t work.
03
Get the full picture
Sign in with an active account, select Connect device, and choose your phone in the browser prompt. Keep it connected while the information is read.
Fastboot & Xiaomi Recovery
Xiaomi / Redmi / POCO, Motorola, Pixel, OnePlus: switch off, hold Volume Down + Power.
Huawei / Honor: connect the cable, then hold Volume Down while the phone starts.
Xiaomi Recovery: hold Volume Up + Power, choose “Connect with MIAssistant”, then press Xiaomi Recovery.
Qualcomm EDL: with the phone in Fastboot, press Fastboot to EDL. It restarts as QHSUSB__BULK (05C6:9008). Then press Qualcomm EDL. 0016 reads the chipset, serial and storage. If the phone stays in Sahara, press Send programmer and choose the loader file for that model. 0016 does not include a loader and sends only bytes from that file. When Firehose is running, Read saves a full partition and Load writes a file that is exactly that partition. Demo writes the backup partition from a backup.img you choose, and only when that file is exactly the partition size. Tick partitions and press Save ticked to save each full file. Tick Restart the phone when this finishes to reboot after Read, Load or Demo. Cancel stops a long read. A programmer you have used for that chipset is remembered on this computer, and 0016 still asks before sending it. The Helper's own page has the same partition list when Chrome cannot open the phone, and it keeps the saved files in one folder on that computer. Nothing else is erased.
MediaTek: switch the phone off, hold Volume Up and plug in, then press MediaTek. 0016 reads the hardware code. It does not send a download agent.
Unisoc: in Download mode (USB 1782:4D00) press Unisoc. 0016 reads the USB name and serial. It does not send a loader.
Motorola and Huawei usually return the IMEI; Xiaomi and most others return the serial number. EDL reads the chip serial, not the IMEI.
USB debugging (ADB), phone switched on
Turn it on: Settings › About phone › tap Build number 7 times, then Settings › System › Developer options › USB debugging on.
Plug in, click USB debugging (ADB), choose the phone. On the phone tap Allow (tick “Always allow from this computer” to skip it next time).
Reads: brand, model, codename, serial, Android version and security patch, build, baseband, bootloader and verified-boot state, SIM and network, battery level, health, temperature and cycles, storage, RAM and screen. Nothing on the phone is changed.
The IMEI is not shared over USB debugging: dial *#06#. Turn USB debugging off again when you are done.
Modem & Download mode
Read via modem (IMEI): phone switched on and unlocked, connected by USB. Choose the “SAMSUNG Mobile USB Modem” port.
Download mode: switch off, hold Volume Up + Volume Down and plug in the cable, then press Volume Up. 0016 starts the Download session before it reads the model.
Firmware: after the model is read, choose BL, AP, CP, and HOME CSC if the customer's data should stay. 0016 does not include those files. A CSC that clears the phone, a partition table, and a storage erase are not offered.
Share with an admin: on the Helper page, press Share this phone with the 0016 admin and type the code here while you are signed in. The phone stays on the shop computer for 30 minutes. A site admin uses it from Admin → Shared phones. The admin does not get the USB port.
Exit Download mode: use the button, or hold Volume Down + Power for 7 seconds.
On Windows the Samsung driver can block Download mode in the browser.
iPhone: switched on, Recovery & DFU
Switched on (normal): unlock the iPhone and connect it. If it asks “Allow accessory to connect?” or “Trust this computer?”, tap Allow or Trust. Reads the chip, likely models and ECID; for the IMEI and serial number use Recovery mode.
Recovery (iPhone 8 and later): press Volume Up, press Volume Down, then hold Side until the computer-and-cable screen appears.
DFU: Volume Up, Volume Down, hold Side 10 s until black, keep holding Side and add Volume Down for 5 s, release Side and keep Volume Down 10 s.
Exit DFU: Volume Up, Volume Down, then hold Side until the Apple logo.
Close Finder, iTunes and 3uTools first.
Questions
How do credits work?
A successful first check of a device costs 1 credit. Rechecking the same IMEI on the same account is free. Incomplete reads cost no credits. An administrator can add credits to your account.
Why isn’t my phone showing up?
Check that your device is in Fastboot mode, try another data cable or USB port, and close other tools that may be using the connection. Windows may need the manufacturer’s USB driver. Some manufacturers do not expose a compatible Fastboot interface.
Which browsers can I use?
Use a desktop Chromium browser with WebUSB, such as Chrome or Edge, over HTTPS. Safari and Firefox do not support this connection method. Browser compatibility is shown in your studio.
What can 0016 read?
Device model, IMEI, and hardware variant, when exposed by the bootloader. This is a device-information tool; it does not run a complete hardware health test. A missing identifier may mean the manufacturer does not expose it.
What happens to my device information?
Successful and incomplete checks are stored in your account history on the server. IMEI values are masked in the interface by default. Your administrator can access inspection records to support your account.
