Fix HTC EVO 4G LTE after System Wipe
I put together this short guide in order to help users fix their phones after wiping out their OS (Operating System). This guide assumes that your phone is unlocked and has a custom recovery installed on it, and that no ROM or back-up is available to install from the phone itself. Simply follow the steps below to get your phone back up and running.
1) Download a ROM to your computer.
2) Boot your phone into recovery mode. You can do this via the bootloader menu (check out my Hboot guide in my sig if you need help navigating the bootloader menu).
3) Connect your phone and computer via USB cable.
4) Select the "Mount" option in recovery. Use the checkboxes to select which storage you'd like to mount (internal or MicroSD), then hit the "Mount USB Storage" icon. Go to your computer and move the ROM to your phone. Once complete, you can unmount storage (as an alternative to this method, you can boot into the bootloader and connect via Fastboot USB mode and push a ROM from your computer to your phone's internal or external storage. Remember, you need to have a working ADB/Fastboot environment installed on your computer).
5) Do a full wipe. On the newer versions of TWRP, select "Advanced Wipe" and wipe cache, Dalvik cache, data and system. Then flash your ROM. Pay particular attention if you're S-on, as you will most likely have to install the ROM kernel separately from the ROM itself. Just check out the OP for the ROM you're installing and see what the instructions are. If you're S-off, just flash the ROM zip and reboot to system.
If you have an issue where your internal storage is corrupt and fails to mount in recovery, follow the steps above to mount your internal storage to your PC. You should be prompted to format your storage. Just follow the on-screen instructions on your PC. Keep in mind that formatting your internal storage will erase it, so it's good to have a back-up of your internal storage elsewhere.
If you need drivers for your computer, look here. Thanks CNexus for the thread. You can also install HTC Sync manager for the latest drivers.
If you need to set up ADB on your computer, this guide is easy to follow (credit to Jerry Hildenbrand at Android Central for the write-up).
An easy ROM to install if you're S-on running Hboot 1.15-2.09 is MeanBean, since it has a S-on kernel installer built in. Simply flash the Rom zip once and reboot from recovery. The phone will boot to the HTC splash screen, then back to recovery. Flash the ROM zip again, and reboot. I've included a link to MeanBean here. Thanks to MikeyXDA for this ROM. You can also run a RUU from your computer to get a OS installed on your phone.
***If you are on the new partition layout (Android 4.3 Hboot 2.10) the above method will not work. Re-run the 4.13.651.4 RUU while the phone is booted to the bootloader and your device and computer are connected via Fastboot USB. If you're S-on you will need to relock your bootloader prior to running the RUU. If you're S-off simply run the RUU. Alternatively, you can download a ROM based on the new layout and follow the steps outlined at the beginning of this guide.***
Links to all applicable RUU's for the EVO LTE can be found in the OP of my Hboot guide.
