[Q] TWRP backup, now bricked
I posted this elsewhere, as XDA was in the blocked sites.
Only 3 hours left at work now though, and for some reason, all sites seem to not be blocked! (Who knows how long this will last)
So, long time android user here. Yet, for some reason, I have never, EVER done a backup.
Never needed to. Odds are, stock backups are online if you REALLY dun goofed, but I never really have data I care about between wipes, phones, and new ROMs (I would, but google backs up 99% of what I want backed up). However, only one ROM has 4.3 for my phone from a ROM maker I trust. However, since I put so much work into my current setup, I thought that I should do a backup, for once, since I was assuming the 4.3 build may have issues, I'd rather restore a backup then reflash, and spend a good hour gettings all my settings and app setting restored.
Info, before I get to the problem.
Optimus G for my phone, running on the Sprint network. I'm using a rootbox ROM, which is synced to the very latest kernals. Everything has been running flawlessly on my phone for a while now. I am using TWRP recovery, and the ROM is 4.2.2, with stock gapps (not that that matters, but I info is useful to someone). Also, the phone was at a 72% charge.
So, I start the backup, going well, although a tad slow compared to a wipe or flash. Then the screen goes black. I'd say the bar was about 30% finished in TWRP. I thought it may have been the screen going in to sleep mode, as it's done this when I leave the phone sitting after a flash, but alas. It was not. The power button did nothing. So I hold the power button, turn it off. Nothing.
Now here's the fun part. I CAN get in to the alternate booscreen. However, on my phone it's....just a screen. There are no options, and I don't remember anything beyond when getting it the instructions were "press down on the volume key twice and press power to enter into recover mode" which, does not work. The phone has been VERY weird at this point. When unplugged, nothing can happen at all almost as if the battery is dead. Sometimes trying to get into the bootloader the LED light flashes red, along with the "hard" key button lights flashing (what are those called? The hard keys on phones that aren't keys, but a surface you touch. I refraid from softkeys because that usually is talking about the NavBar). I CAN get in to download mode, but right now I am at work, and will be for the next 6 hours. Many, MANY sites are blocked here, and thankfully, tek syndicate is not one of them. However, I am very limited and no sources to download any software needed to fix the issue.
If no one has suggestions beyond using download mode, feel free to post those links. I could most likely find all that info on my own when I get home. I'm no stranger to android at all, although never.....dare I say it, bricked anything before. I assume this would be not that hard to fix with download mode, and I'm hoping that maybe someone has a link that works here at work, and can be used with these computers.
The alternate question, or, TL;DR How could performing a backup cause a brick? I was backing up using TWRP, for the first time, on 4.2.2 android and during backup, black screen, can use bootloader, and download mode, but will not boot into ROM or recovery, as well as no actions at all without being plugged in.
Thank you in advance!
If this post in convoluted, I'm basically asking why this would have happened. After that, any suggestions to fix it without using download mode would be good, but I will take download mode suggestion as either the site may not be blocked here at work, or I could use the link when I get home later.
