Flashing custom ROMs on Android devices can sometimes lead to errors during the recovery process. This guide addresses the two most common errors you might encounter: Error 1 and Error 2, along with their respective solutions.

Error 1

Error 1 is probably the most common error, with several potential causes such as corrupted zip files or issues with SD cards.

Solutions

1. Avoid using browsers like Chrome for downloads. Use download managers like 1DM or ADM, which you can find on the Play Store.
2. Flash crDroid Android 10 ROM first, then flash the ROM you want to install. This method works 90% of the time.
3. Flash stock MIUI once as a preliminary step. This can also resolve the issue.
4. Un-mount all partitions from the mount section except for data, SD card, or OTG (if you are using those).
5. Avoid using cheap or corrupted SD cards. Flash the ROM from internal storage if possible.
6. Ensure you are using the latest recovery version. Keeping your recovery tool up-to-date can prevent many common issues.

Error 2

This is another common flashing error, often related to device compatibility or ROM integrity.

Solutions

1. Change the codename in the updater script to "phoenixin" or within the recovery itself (some recoveries offer this option, but TWRP does not).
2. Ensure the ROM is intended for your specific device. Double-check the ROM’s compatibility before attempting to flash it.
3. If you encounter this error while flashing MIUI, try using LrTWRP. This version of TWRP can sometimes bypass compatibility issues.

Reboot to Recovery After Flashing a ROM

If you need to reboot to recovery after flashing a ROM, follow these steps:

1. Flash MIUI or crDroid A-10.
2. Then re-flash the ROM you want to install. This method has proven effective in many cases.

Conclusion

By following the solutions provided for Error 1 and Error 2, you can effectively troubleshoot and resolve common flashing issues encountered during the recovery process. Ensuring you have the right tools and steps in place will help make your custom ROM flashing experience smoother and more successful.
