Hey, I recently tried using AnTuTu to benchmark my (non-converted) Optimus G and the phone just shut off on me. From there I couldn't get it to turn back on, it will only boot loop the charging logo when I plug it in. I'm pretty sure the partition tables are all messed up.
Anyway, I'm attempting to completely flash back to stock with LGNPST and I've tried every combination of installing drivers and I've tried going to "Tools>Load Ports" (can't remember exactly what the menu said, I'm using a mac now). However I plug the phone in, however, it isn't recognized, I've tried opening the program with it plugged in in download mode, and plugging it in when the program was running in download mode.
Any suggestions?
Thanks a bunch!
EDIT: Probably worth noting that recovery gets stuck at a black screen and no adb access. Can't flash a ROM using fastboot flash zip, I get the following error "FAILED (remote: partition table doesn't exist)", that being said I have access to the bootloader and fastboot.
Gotta take the battery out. Use a t5 torx for the bottom 2 screws, then starting by the sim card slot work an old credit card all the way around the edges popping off the little plastic clips. Gently lift off the back. The camera will still be attached to the back so be careful. Gently remove the camera from the back panel of the phone (not the ribbon cable!) then remove the 2 tiny phillips screws holding down the battery connector, pop it up, wait a few seconds and reassemble. Be careful when putting the camera back in the housing, and put the top of the back panel back in first. Sounds like a lot but pretty easy if you take your time.

I Think Before Messing With Your Device Internals,Do A Overnight Charge,It Should Probably Solve Your Issue.

Make sure you run LGNPST with admin rights.

Running TnT lite v5. Normal boot was fine except for an error "System UIDs Inconsistent". I wanted to fix that but whenever I try to boot into recovery it hangs on the Viewsonic screen after the 2nd line of text (something like "Booting recovery kernel image"). I do not have an external card in it right now, but I have tried booting from one with no success.
Any ideas?
Thanks
Another bit of information, "lsusb" does not show the tablet.
happened to me to. put in the gtab-cwm-v08.tntlite5 before i was gonna run the 5.0 tntlite. what i´m gonna do now?
I found this thread:
http://forum.xda-developers.com/archive/index.php/t-934595.html
Looks like there is a process that involves opening the device up. Does anyone know if this actually works? Here's the process outlined in the thread:
1. Disassemble the tablet. Remove the four rubber stoppers on the bottom of the tablet (put them aside). Next, unscrew the screws under them (keep those too). Next we need to get the back half of the tablet off. Put the tablet face down on a piece of paper or another protective material. Gently work one corner of the tablet until the two halves are slightly separated, then use something thin like a business card to keep them slightly parted. You can then use something thin and strong, like a plastic gift card to zip around the edges and break the seal. Prying will only damage your plastics.
2. Disconnect the battery lead (a flat connector with multicolored wires, probably held down with tape. Look near the battery.)
3. Connect the device via USB.
4. Short (connect) the four contacts circled in the photo. (A smallish square of tinfoil works well for this. Be careful.)
5. Press the power button for 2-3 seconds and release.
6. Disconnect the tinfoil shorting tool.
7. The APX device should be detected on your computer.
8. NVFlash a working bootloader.
9. Disconnect the AC adapter.
10. Reconnect your battery.
11. Reconnect the power until your device is charged.
You have pushed a wrong set of buttons ... you need to hold the "volume Down" botton and then power it up so you can restore it with NVFLASH, you will have a BLACK screen... no need to opend it ... if you see a message on the screen it's means you only boot in recovery (Volume up + power)
tried this...nothing different. still frozen. any other ideas?
[Alternative Low battery in Ap fastboot fix
Tested and confirmed to work on Verizon Motorola Droid RAZR XT912
I softbricked my Verizon Motorola DROID RAZR XT912 while testing some stuff out when it got bootloops. I hard reset it by holding the volume down and power button for thirty seconds. when it restarted it got the all black screen with white letters saying Boot Failure in Ap Fastboot mode. I could not flash the factory Rom back on it to make it operational again cause my battery was below 50% charged. So here is what I did.
I used a 600ma charger cut the end off and then cut the wire coating back exposing 3/16 of wire. With charger unplugged I attached the red to the + and the black wire to the - terminal being extremely careful not to touch anything else in there causing it to arc and possibly causing damage. I recommend that you download the IFIXIT APP in the market to a tablet or use their website so you can get the instructions on the removal of the back plate without breaking or cracking it. Once removed you can use the torx screwdriver to remove the negative screw. It has a washer too I just placed the wire neatly under there making sure not have any individual wire sticking out everywhere and re-tightened it. Then done the same to the positive side.
Now that you have done this you should very carefully flip it over taking extreme care as to not have the wire break or fall out. I placed mine over the edge of the table so I could inspect it before plugging it up. If all is good plug it up then hit volume up and down plus the power button at the same time. When done correctly the Boot Mode Selection Menu will show. Use volume down to scroll the list to AP Fastboot highlight it select by pressing volume up. Usually it'll go straight there cause it's bricked and in bootfailure. The RAZR will now say BATTERY OK. Run RSD Lite and install your Fastboot files with RSD5.7
Fast boot file listed below is for the verizon edition.
ICS 4.0.4
VRZ_XT912_6.7.2-180_DHD-16_M4-31_1FF.xml
After it fully installs turn device off and carefully remove everything paying close attention not to touch the cut wires to anything and also be very careful with your torx screwdriver. Then snap the back cover on and power it back on. Worked twice for me since it keeps soft bricking every time cause of Bootloader being locked.
Update, Thanks to whirleyes and the app called Bootmenu which allows you to partition some space for a second system (dual boot) i'ts located on the market. I'm able to flash without any problems now.
If you find this helpful give thanks.
600ma charger was the one i was willing to sCrifice to get the phone back up and running. Search motorola droid razr stuck in fastboot with low battery on youtube or mikevipsr. I really didnt want to put a charger with to much charging power like 850-950ma cause i was thinking its hook up directly to the battery and its not getting filtered through any hardware before it gets there. I had to open my phone and do this out of nessicity since my rom crashed and i was in boot failure. All the button presses and didnt work.
I need to update this because i do not need any help with clockworkmod. I have moved on to a really great app called Bootmenu its even on the market and the razr guy has a great video up for it.. http://www.youtube.com/watch?v=KmMgcVi7tgU&feature=g-user-c

Can you do this with just a regular USB cable and USB power adapter?
Any usb cable preferably the factory cable that came with it in the box.

If it ain't broke...see if it'll go faster. That's what I tried, BUT ended up
If it ain't broke...fix it 'til it is!
I posted this in XDA Assist, but as I suspected, I've well hosed this one, with probably no way up, but here goes. I promise, next time I won't be so wild. I know now that if you must burn your bridges, don't be standing on them!
Android 4.2.2
It's rooted with Vroot, has SuperSU and Titanium Backup Pro, shows rooted.
Had ADB working, tablet taking commands.
I first tried to put in CWM recovery for the HSG1279, supposed to be the same tablet, just bigger screen. I don't even know now whether THAT'S true or not.
Started in recovery mode, but was just stock, so I tried arctools to put in a generic Rockchip CWM 6.0.3.1. That's when things started going sideways. The install hung (imagine that!). The arctools had a forced restart of some kind, so I used that. When I got back to my home screen (whew!), I used Titanium backup to see what recovery mode looked like. The tablet went dark, and would not power on. I did the paper clip trick, which got it started, but did NOT wipe anything out, so not a hard reset. Any time after that when I tried to restart in recovery mode, the hard shutdown with the clip was required. Yesterday afternoon, I went off to work for about 3 hours, leaving the tablet on, but in standby. When I came back, the tablet was dark and no amount of paper clipping would help. It would not recognize a charge. Not being one to duck a fight, I opened the case and unsoldered the black (-) wire at the PC board. The battery measured some voltage, but I didn't notice how much, about 1/4 on the 25v. scale. I soldered it back on, put it back together without any further incident. It sill does just what it was doing...nothing. I have noticed that when it's plugged into my PC's USB port, and I reset with the clip, Unknown Device shows up in my PC's Devices And Printers list. When I unplug the cable, I get the stock Windows "be-boop" USB removal sound. When I plug it back in, I get a short "boo-boo-boop" sound. That's where it is now. Anyone have any ideas on getting it going again? For me, no more trying files that aren't made specifically for this oddball tablet. This has been a fairly expensive lesson in that.
Thanks for any help.

My Mi Pad 2 is fully bricked, is there any solution?
this is what happend, I install LineageOS on it and it was fine, but then I wanted to change the recovery, then the OS wont boot so I try to put the old recovery in it, it also fails, so I tried to put windows on it, by booting an USB pendrive and mouse with an OTG cable when it start, but a signal of battery error appears, and now it wont boot at all. If I connect the tablet to the wall power, it shows me 0% loading, I left it for like 2 or 3 days connected and nothing, still 0%, when I try to power on the tablet, it shows me the battery icon with a warning sign /!\ and wont show me the "Mi" logo, just direct to the warning sign.
The pc wont recognize it either, and wont work any buttons combination, is there any solution?
This might be over 2 years late for you but the same thing happened to me and I thought i'd post the fix incase anyone else comes across this thread.
[FIX] Open the backing and simply untether the battery ribbon cable, im not sure if leaving it unplugged cleared any held memory so I left it for a good minute or so before reconnecting. Screw it all back together, turn it on, should work fine

remove the 2 screws at the bottom (they're torx t3? I think. a good set of precision screwdriver bits should have it) and use ideally plastic spudgers to spudge it out. its clipped in but it's really easy to remove. the back panel comes off by itself, and the rest of the tablet is self contained in a magnesium frame attached to the screen.
i was pretty impressed by the construction really. super solid!
So... I had the Mi pad 2 laying in my house running on MIUI 9 and one day I got curious and tried to unlock its bootloader.
I didn't remember my password and the recovery phone no. is discontinued now. and I couldn't change it or sign out.
So like an idiot, I factory reset it. And now it's asking for a password for the last mi id.
can anyone help me? Will and edl flash do the work?
THANKS
