I tried to install a font using Font Installer on my LG Motion which was rooted, and it went into a boot loop. I hard reset it, but it is still stuck in a boot loop. Help me out, please? If I need to download any files, please, give me a link.

  • Might not do the job, but worth a try: have you removed the battery for 10s+, and then re-inserted it? Oh wait, that is a hard-reset -- if you did not mean factory-reset (which would be a last ressort as well). You could try booting into safe-mode and see if that is possible. But if you meant factory-reset when you wrote "hard reset", that won't help either. – Izzy♦ May 28 '13 at 20:40
  • Once again, I hard reset it because it went into a boot loop. But it is still in a boot loop... – Eff EL May 28 '13 at 21:05
  • Once again, too: What do you mean by "hard reset"? Check the hard-reset tag-wiki (hard reset = take out the battery, put it back again), and the other links from my previous comment -- and then please clarify what you really mean. Often people say "hard-reset" when they really mean "factory-reset" -- and I'm not sure if this is one of those cases. Unless you clarified that, it's hard to help you. – Izzy♦ May 28 '13 at 21:09
  • Actually, Hard reset was the short term originally used for "Factory Hard Reset," which replaces safe mode when it cannot be booted. But if it pleases you, Factory Reset. – Eff EL May 29 '13 at 2:59
  • Eff, it's not that I have it with words (as for me, it could be called "potato chipping"). But you will admit that there's a little difference between taking out the battery (hard-reset), and a factory-reset, technically spoken? :) Usually, a factory-reset should solve this issue. So if removing power completely for 10s+ doesn't do it, that's really weird -- and might require a flash (see: Where can I find stock or custom ROMs for my Android device?). Did you modify something in /system before this happened? – Izzy♦ May 29 '13 at 6:09

Usually, you use a to solve a boot-loop -- but it doesn't cause one. Sometimes, a (i.e. removing the battery for at least 10s) solves things, as it makes the entire device powerless so nothing can "stick". In your case, however, none of the two could help:

Analysis

As it turns out, the culprit is a font-package you installed. A little background on that:

While "normal apps" get installed into the /data partition, more system-oriented stuff (font packs, specific frameworks, things changing core system behavior, modded notification bars, and more) need to reside in the /system partition. Now, when it comes to a factory-reset, the /system partition is never touched -- so if things get messed up there, they stay messed-up. As in your case, obviously.

So what's the remedy? You no longer can boot up normally, as your device is stuck in a boot-loop due to some system mismatch. You also cannot help yourself booting into to remove the culprit; while this would work for user-space apps (which are not run in safe-mode), you won't even be able to boot into this mode with a messed-up system. This leaves two things:

  • if you still can boot into , you might be able to undo your changes via adb shell from your computer. But this usually requires a custom recovery (such as or ) on your device, as stock recovery won't give you the required root access.
  • if you cannot boot into recovery mode, or have no custom ROM installed on the device: re-flashing your will fix your issue for sure, as that would wipe /system and install everything anew. With a this usually also means you lost your access. Flashing in your situation can still be done via either recovery mode (if you can boot your device into it), or mode (if your device supports it; I've read many LG devices need to have the unlocked to do so)

Flashing needed?

You might want to check Where can I find stock or custom ROMs for my Android device? for the to be flashed. Further hopefully helpful links include:

Abstract from the latter link:

  1. get the official firmware from lg-phones.org
    • KDZ_FW_UPD_EN to be extracted to your PC
    • LG Motion .cab firmwares need to be converted to .kdz (see Official LG Motion 4G Firmware Download for details)
    • msxml.msi needs to be installed to your PC (ouch, Windows only, sorry)
  2. get the USB drivers from lg-phones.org and install it
  3. start KDZ_FW_UPD.exe
    • "Type" choose CDMA
    • Choose in "Phonemode": Emergency
    • Click the folder icon and choose the .kdz file that UpTestEX_mod2_marwin.exe just made (in step 1).
    • Click "Launch software update"

The rest should run automatically.

Postscriptum

I included a bunch of tags into this question. You might want to follow them:

  • click them for questions relevant to the topic
  • better: hover your mouse over it, and follow the revealed 'info' link to their "tag wiki". Out tag-wikis often include a good description as well as some "first aid"
  • hovering your mouse over them lets you also chose to see...
    • the most frequested questions tagged such
    • top users contributing to that topic (might be helpful to see their profile, as they obviously are "experts" in that area that might reveal further interesting and related questions/answers)
