easy way to start kf without original battery - Kindle Fire Q&A, Help & Troubleshooting

Hi there!
I'd tried to find easy way to boot my KF w/out original battery and didn't found anything.
All in all I discovered an easy way to boot your KF:
1. disassemble your KF
2. disconnect its battery (isn't soldered, connected w/ socket)
3. connect pins SCL and SDA with wire (watch photos, connection is marked w/ yellow pen)
4. connect your Li-Ion or Li-Poly 1S 3.7V battery (red wires: +, black wires: -, are marked too)
5. wait about 3-4 secs
6. cut wire between SCL and SDA (when KF boots it will continiously switch boot menu)
7. when you cut wire, KF will stop switching, choose "normal boot" with power button
8. well done! it is booting :3
Tested w/ cyanogenmod, eth works well.
When it is on, battery indicator will show "?" and 0% of charge. It means nothing, your KF won't shutdown itself until you discharge battery about 3.1-3.3V)
A bit of photos:

Sorry for my english, i'm russian and it's quiet difficult to learn this language w/out practice.
UPD: moderator! if i'm wrong, please, move this topic to right forum :з
UPD2: logs when it is shutting down w/out original battery. when i use my way to boot KF sends I2C read: I/O error many times and then it boots ok

[mod] Revive your phone if you don't have enough battery!

This is very iffy, and DO NOT TRY THIS IF YOU CANNOT FOLLOW DIRECTIONS, I AM NOT RESPONSIBLE FOR YOUR PHONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This is your problem not mine, if you mess it up
My apologies for supersized images, but they get the point across.
Things you will need.
1. Battery bricked Photon/Motorola Device (x/x2/d/d2/etc)
2. A SPARE USB CABLE, NOT YOUR MAIN CABLE! (Don't be dumb!)
3. Your usb cable you use to to connect your device to your pc.
Directions as follows:
Step 1:
Splice your cable by cutting off the end of the cable (where you would input it to the phone)

1a: strip the wire about two inches so that white,green,red,black wires are all showing, pull back Green and white wires, as they will not be used.
1b. Strip the red/black wire so they look like below, then wind them up like so.
2. Pull out the battery in the photon.
2a. This is where this gets tricky, look the postive/negative logo's on the battery above the terminals, place the red in the positive terminal and the black in the negative terminal.
2b. Place battery in phone with wires connected to terminal!
3. Plug usb cable into your pc, then connect your usb cable to the phone, wait 2 minutes, and you should no longer have battery too low messages!!!
Remember when you disconnect the phone, UNPLUG THE BATTERY USB CABLE FROM THE PC FIRST OR YOU WILL **** UP YOUR PHONE'S BATTERY SENSOR!!!!
This will work on ALL motorola devices, and most phones period.
This is like jumping your battery from a car.
You're welcome for saving you money , this helped me out SO MANY TIMES.
Luckily I'm not in need of this but I was just wondering earlier this morning if this would be possible.. I figured I'd find out the hard way if it came down to it, but now I know it should work!
Thanks and excellent guide

I went into the water to do some video and after about 14 minutes of video on my Z1C reboot, after the reboot I take another video about 4 minutes after that turn off completely, I go out of the water and did not want to turn on, 3 vibration and black screen, I remove the simcard and the memory and let some air, I notice that the simcard there is a bit of water a few hours after arriving home plug my phone to my pc et woilà my Z1C turns on normally.
What could it be?

My Dumb Ass told my Wife's Parents I could fix their tablet (Stuck in Reboot Loop).

Good Morning!
I have lurked hear on and off when I had problems before with my Samsung phones so I thought I was qualified to help my Wife's parents with their Galaxy Tab 3 10.1. They aren't techy and will buy something new at the first sign of trouble. I was just hoping to save them a couple hundred bucks. All they told me was that it wouldn't turn on. I'm not a techy guy myself but I know how to google and follow instructions so I'm the de facto IT guy in the family.
What it appears is happening is that it's stuck in a sort of reboot loop. I read a bunch of threads about starting in recovery mode and hard resets or hooking it to the computer and updating it from there but nothing works. The computer won't recognize it when I plug it in since it's constantly rebooting. None of the button combos (power+volume up+home, etc.) work either.
I made a quick YouTube video of the problem but as a new member I can't post it but it just flashes the "Samsung Galaxy Tab 3" on and off until I suppose the battery dies.
Any ideas on what else I could try?
If this battery connector is severely cracked, your tablet won't be able to boot.

You can try this, press hard on the back cover near the center to see if it can boot or remove the rear cover and press directly on the battery connector while power on.
Power + Volume Down ( next to Power Button ) is Download Mode
Power + Volume Up is Recovery Mode.
If you cannot access these two modes, may be your power or volume buttons are not working, I guess. The flex cable for these 3 buttons only few dollars on Ebay.

[solved] ZL dead, no reaction (because of faulty battery) - emergenc charge method

I had an issue with my phone and resolved it, this is me sharing this particular error and solution.
First the Problem:
I had my ZL running low on charge and the next morning it would not react to anything.
pushing buttons (and a combination of buttons, like power+volumeup) did not work
connecting it to the charger
connecting to pc did not show the device or trigger a reaction (did not show up in device manager)
Solution A: Install a new battery (e. g. via IFIXIT guide).
Solution B (try on your own risk!!!):
Open the backcover of the device (i used the IFIXIT disassembly guide).
You dont need to remove the main curcuit board, you just need to disconnect the flex-cable of the battery shown in the picture below, the pink marker shows the battery connector (top right).

I bent the connector so that it was accessible with my universel charger, which looks like this
I connected the two marked connectors go to the + and - on the flex-cable of the battery and the charger signaled that it was charging the battery.
I guess you can use any universal charger of this fashion. Do not use your standard usb charger, it's dangerous!
After 10-20 minutes i reassembled the phone and was able to charge it normally, start it up, etc.
I'm no expert but this is what I think happend:
A completely drained and at the same time worn out battery did not allow chrging the divice. Mine was 20 months old. The phone controls the charging process I think, so maybe there was not enough power left for that.
I will be replacing my devices battery with a new one and I suggest the same I you have had the same problem.
I hope this helps

Samsung Galaxy tab S4 - VZW Bootloop / Splash Screen

Boot Looping Samsung Galaxy Tab S4 scenario​1- If you cannot access your device, download the ADB and latest version of Odin
2- Hold Volume Down + Power and HOLD (I'm talking even after booting, I believe this clears the cache and re-initializes
device lock
3. Repeat. . . .
Many people give up or move on to something else at this point to try to fix, if it's still not working
squeeze the front and back panels together (softly) to ensure no loose Display cable,
then... hold
VOL+ VOL- + PWR This resets the device as if you were pulling a physical battery out, clearing the cache, repairing security program. REPEAT until Tablet says cannot initiate Encryption service, and will repair itself. IT WILL REBOOT
No need to hold the buttons this time as you will see your login screen.
The Secret is VOLUME UP - VOLUME DOWN + POWER for 45-50 second intervals.
Took me a day and a half so I figured I would save you some trouble.

+Yes it is still possible that this does not repair your tablet, I do not suggest taking off the back chassis as I have seen professionals break and hard brick devices this way.
IF YOU DO - Use guitar picks and or the official phone repairkit tool. YOU WILL need it.
