At The Beginning
I have a Cingular 8125 G3. I first began flashing new roms onto my phone 4 months ago after I unlocked it using "the definitive guide to unlocking phone" by DrDot. Everything went smoothly.
The Start of the Problem
A couple days ago, I was running the TNT 1933 with CoolCamera. SUDDENLY, my phone started to reset itself everytime I went on the internet, or downloaded emails.
The Attempted Fix
I decided to flash my phone to another rom, so I began by flashing it back to 1.05 rom that you use in "the definitive guide to unlocking phone" by DrDot, before flashing it to a better rom.
The Final Finally
In the middle of the udate process (for the 1.05 rom), my computer screen said, an error occured, and to redo the update. When I looked at my phone, it started to blink on the 3 color bars. It kept blinking until it died. Now it cannot read a charge or turn on. I tried leaving it on my charger overnight, hoping it would charge, and nothing (not even the charge light on the phone would go on. I also made sure the phone charger was fine, which it is. I even tried to charge it on the usb cable, and occassionally I see the 3 color bars flash). My phone is bricked.
buy a new battery and then flash a new rom
It is not bricked
I will try that

Okay, I'll try that. I'll let you know tonight.
keep in mind that when you are in bootloader mode (tri-color screen) the phone cannot be charged, this is why you should always have a 50% battery level when you flash a rom. A new battery should definately fix it, id flash it with a manufacturers rom that is known to work like the wizard love or t mobile 2.26
Everything is good thanks
I put a new battery in there and it is fine now. Thanks. How can I delete this thread? It is pointless now.
bringing the emty battery UP again with home tools
Please note that the following is highly experimental and if you consider to use the following "workaround" it is TOTALLY AT YOUR OWN RISK and i can not be held responsible for damages caused to your hardware or to yourself!!!!!
I had the same issue 2 times till now, what i made:
i took a USB cable (like the normal one i use for the wizard to connect it to the pc), cut off the mini usb jack. There are 4 wires in the cable we need the black one and the red one. The red goes to the + of the battery and the black goes to the - of the battery (on my battery the + and the - are marked), if on some batteries there are no marks for + and - you can use multi zet tool to check. The next thing is to put the cable in a free usb on the pc and the wires on the battery. Its quite difficult to find out the right place and position for charging the battery this way - but you actually need to charge it this way not more than 5-10 mins. Then you can boot normally and continue charging the "right" way. Use your old battery again. Thats all...
Regards
So I've fully discharged my phone following the instruction given by a battery calibration app. But now the phone won't even turn on and I can't even recharge it. I tried to pull the battery out and put it back in, and then plug in the cable and turn on the phone, but hell no, the phone gave only 8 short blinks and 3 long blinks from the amber colored led and went dead.
I don't know if this is related to MDJ's unity V5 beta kernel, but my phone is unwilling to recharge while it's off. Can somebody help please?
Btw, I can't even boot into bootloader by holding vol down after pressing power button.
Charge your battery min.3.6v on external charger or another phone and then put it back.
lol found a solution, a badass one too:

Ghetto Solution:
I have a spare, semi-busted USB cable.
I stripped off the insulation and exposed the green, white, black and red cables.
You only need the black (-ve) and red (+ve) cables for this effort.
Use any means you have to get expose the actual wiring and be sure to match them properly to the corresponding contact points on the battery.
The idea is to directly place the positive wire on the positive terminal of the battery and vice versa for the negative. The plug the battery into the phone.
What I did was loop the wires around the leads that would be in direct contact with +ve and -ve inside the phone itself, plugged the battery back in the phone and then plugged the USB cable into my laptop.
The phone booted right up.
Seems to be working thus far even though its still "off". I have a solid amber light and I'll leave the phone for a little bit before I try to boot it back up.
I hope this helps.
DISCLAIMER: I take NO responsibility for any damage (physical, psychological or emotional) you or your phone may incur should you attempt this.
It worked for me.
YMMV.
Be advised and tread carefully.

and if we're not feeling so badass?
I don't wanna go messing with my USB cable, but I'm in the same boat as the OP. When I plug in to wall or computer, there are 9 dim orange short flashes on the notification light, about 1 per sec, and then two longer flashes, and brighter too, then nothing. Any other suggestions that are maybe a little less bad-ass and a lot more usable?
Any help would be GREATLY appreciated!
Hey guys, i've done the search button and still can't find any answers. First of all, all i've done to my phone : S-off, superuser, root. No custom ROM installed. i did that 2days prior yesterday and it was working and charging fine. So yesterday when i was playing paradise island my phone died. I connected it to the USB wall charger and left my room. After 3-4hrs, my phone is still dead. So i thought maybe the USB or wall charger is not working. I tried using my cousin Mytouch wall charger with the htc USB, still doesnt work but using my wallcharger with the mytouch usb, my cousin's phone charges.
When i try to charge my phone, the amber light comes on but its flashing, then after 3 times, light will stop
Troubleshooting i've done
I've tried numerous times to go to HBOOT, nothing
Removed the battery several times, nothing
tried USB charging through my laptop nothing.
Any help guys??
Same issue!
Please help with this!!
CMW
If you search you'll find that there is a problem and after installing CMW Recovery most phones will not charge if they're off, so if you let your battery drain to the last you will be unable to charge your battery trought the phone, no solution at this moment for this
Work arounds
- Charge your battery on a wall charger directly not trought the phone
- Charge your battery on an stock untouched Sensation

Wallcharger, is there one i can purchase??
Is the battery itself the problem?? because t-mobile, will sent me a new battery. I've only had this phone for 3 weeks. IF the battery itself not the problem, they will send me a new phone but i'm assuming that i've going to have to send the old phone back, is there going to be an issue regarding the warranty when i send the old phone to them???
it's not the battery, it's the cmw what's the problem. You have an older version of cmw.
I see, where to get the latest CWM? There's a way to go back to stock right?
Now i kinda regret S-OFF,ROOt, CWM ...lol..-.- i know it's my fault tho...
Once you managed to boot the phone again, you can install rom manager, from there you can easily install the latest cmw.
i have the latest CMW Still doesn't charge when battery at 0%
You would think they would test CMW before releasing....

I used CWM 4.0.1.4. From what i know its suppose to fix the charging problem. As of right now, im trying to manually charge my battery by splitting on of my old USB cable +wall charger. So hopefully this will work.
None of the threads in the entire forum are even remotely helpful if you can't even get the phone to turn on.
I can't reflash the recovery - if there is no way for me to get into the bootloader.
A wall charger hasn't helped - nor my N1 battery taped in.
NOTHING.
Please stop jumping a million steps ahead to reflashing the recovery - start with HOW TO TURN THE PHONE ON - bearing in mind that NOTHING IN THE FORUM so far has worked.

I've been using my brothers G2 battery (which doesn't fit) to turn on my phone.
But since I don't have a universal charger, and my phone wont turn on (I tried EVERYTHING) than there is no point to attempt to get into recovery unless I'm going back to stock.
Tl;DR CWM Needs to fix there shhhhhheeeet.
I finally manage to turn on my fone by splitting my old usb cable...i know somone said, its dangerous but it work for me....so do it at your own risk....now im juz looking for a safe wayto revert to stock w/o cwm,root,super user....might keep S-off tho
Any suggestion
If u need to start you fone....get a spare usb cable...and split it..remove the battery from your fone. Now tape the red wire to positive and black to negative....attach the usb to ur wall charger.....then wait 10- 20 min. Now remove ur battery then insert it back to you phone and turn it on. Once it starts, connect it to ur htc usb+ wallcharger.... once again, someone said its dangerous....so make this your last resort

Yeah. That didn't work for me. After splitting two cables - I decided to cut my losses.
Unfortunately I'm not in the US - and that's where I bought the phone. I'm going to try and find and independent vendor and see if they have a battery I can buy.
If not - I am ROYALLY screwed.
Yeah the battery/cwm combo is ****ed. So angry.
Do you have the one with the blue text? It's supposed to fix these issues
Swyped from my HTC Sensation
Sorry to revive this thread, but I am in the same boat. After trying to flash android on my brother's hd2, I noticed that the battery died. I cannot charge it since it has no ROM currently installed... Has there been a fix?
Its all in chronological order. As the title says my phone wont charge. USB CABLE from PC or wall charger it just wont charge. Following some threads i also removed the battery and connected it to main but no led would show up. Right now i've removed the battery and charging on universal charger fine,
So here is the history. I dont know what can cause it not to charge. While i was at university my phone fell on the ground. It was not from height as i was just sitting on the sidewalk and it fe ll down. Then I came back home. I have ICS Ruu Saga on it which i'm not happy about and wanted to go back to GB ever since i realized that my camera quality is worse than before and my Subway Surfer game is not smoother any more,
Seeing some threads I selected the recovery option in bootmode (vol down+power). After few second a red triangle came showing ! sign. I removed the battery and re-inserted as the power key wont work. When i re-inserted the battery and powered up but it was different boot method. before selecting recovery option the booting of phone was smooth..but after that it stucked for a few seconds first and then came the home screen.
After all this as my battery was getting low i decided to put it on charge. I connected USB Cable to charge it and realized after sometime it isnt being charged,,,there was no orange led that usually indicates its being charged.
So thats all. I dont know if dropping the phone was cause of it or doing recovery ( note: i never made a backup of my phone every..i dont know why i did it, in hoping that it would go back to GB itself) and the appearing of red trianlge with ! mark and me removing the battery did it.
Please help me. I spent entire night on finding the solution but couldnt find anything.
Phones warranty is over..Its not rooted or has CWM as i dont know that stuff.

Please help me! :crying:I have already went to different forms and read several threads, but I cant find any solution. I have a Samsung Galaxy tab 2-P3110 that is completely restored to factory settings except that it is still rooted. I tried to update its OS to 4.4 manually by using CWM 6.0.2.7(which is specifically for my device), flashed it using heimdall. At first it worked out fine, booted into CWM recovery mode. But i think i have downloaded a broken OS upgrade, because when i tried to install the package it said it was aborted. After that i never tried to install it again but started to wipe every data that i can wipe, I wiped the cache, the dalvik cache, even restored it to factory settings again. Then i selected boot system now,then it goes into a boot loop in CWM recovery mode, after trying some things like booting it into download mode and pressing the power button down for minutes but it doesn't turn off still the boot loop. Then I emptied the battery, didn't touched it for a couple of days, then charged it for hours, but when i tried to press the power button it didn't boot looped into recovery mode, and it didn't boot at all, all i can see is the empty battery logo when plugged. Even tried pressing all three buttons, and pressing power+down/power+up buttons still nothing. Is my device hard bricked? Help me please!!!
Update: Tried using oneclick unbrick tool (how noobish). It occurred to me that i can't even boot my droid into download mode or even simply boot it for cryn out loud, how can my PC read it. Maybe i should try making an improvised JIG for desperate measures hahaha.

i had a similar problem.. but did you try and go into recovery mode (using cwm)... press volume up and then hold power down until it switches off and then let go of power. you should see the tab 2 logo and after about 5 seconds should go to recovery mode.
volume up is the one next to the power button btw. not sure if that will let you fix it in your case (depending on you having a working recovery) but it fixed my softbrick (did a full wipe in preparation for new rom but rebooted instead of installing a new rom).
Thank you for the advice, but...

Thank you for the advice, but i have already tried that, given the title: Wont Boot, enter Recovery or Download mode. For the past few days I've been trying to accept that my device is officially bricked. Because I have read a forum about the difference between hard bricked and soft bricked, and when my device didn't enter both download or recovery mode I already knew that is a sign that it is hard bricked and that it would be hard to fix it because i cant connect it to my computer and try to force boot it manually. Now I'm feeling hopeless But once again thank you, because u tried to help me :good:

To get to the most critical point first: You obviously didn't read the OP of the ROM thread as "everything P311x Android 4.4.x" needs to flashed through TWRP (recommended recovery for OMNI) or PhilZ Touch or CWM Swipe Edition (later two are recommended for CM11). That being said and out of the way...
- "Bootlooped when attempting to get into CWM"
Well... if your tablet is plugged in to the charger the key combo to either enter recovery or download mode doesn't work. Your tablet needs to be turned off (looooooong pressing power will turn it off in case it hangs) and disconnected from the charger/USB port. Of course, needless to say that you best have 50%+ charge at least.
- "Drained battery, doesn't charge"
No idea what really went wrong in your various attempts to breathe life back into the tablet, but if you drained the battery and now it won't turn on / charge but only show you the "empty battery" sign ... the only way to resurrect the tablet would be to open it up, take out the empty battery and replace it with a charged one to flash back Stock or the correct recovery to go from there again.
I don't know from the top of my head how many cables leads the battery uses to connect to the motherboard, but I assume there are at least three of them (+5V, GND, Charge monitoring). If you can't get hold of a charged replacement battery then you may try to use the trick AdamOutler posted on his YouTube channel? XDA TV channel? some time ago. This involves the use of a resistor across the +5V/GND pins (right there where the battery connects to the motherboard) to trick the charging circuit into actually charging the battery.
However, be warned that taking apart the tablet and tinkering around with the electronics requires SOLID knowledge, otherwise it's just a recipe for disaster (seeing how you already failed reading comprehension prior to flashing a ROM).
As a last resort you may try to post a question in the General forums to try and maybe get a reply on how to get the tablet to charge back up by giving it a shot with Adam's little trick. Alternatively there might also be a way to "hot charge" the battery by connecting it to a suitable power supply for a short amount of time (restoring just a basic charge as you can't possibly fully charge the battery this way - would be way too dangerous without proper charge monitoring).
If you manage to get it back to life you well better make sure you read "everything flashing" the next time you try to flash a ROM... using the totally wrong recovery can have nasty side-effects.
Don't recall if it is a li-poly or lithium ion battery if it is lipo I don't suggest attempting to charge it indoors I set a fire once in a tin pan attempting to charge an rc car lipo pack. It started off normal then about 80% charge it must have finished quickly and exploded yielding a surprisingly large flame.
But if he is right and a charge on the battery will cure it watch it very very closely.
Sent from my XT907 using xda app-developers app
It should be a Li-Ion battery pack.
However, "hot charging" the battery from a power supply is a dangerous task even with "just" a Li-Ion one. It shouldn't be charged for any longer than one hour tops, and depending on the amp rating of the power supply the +5V line should also be choked with a suitable current-limiting resistor to prevent too much current rushing into the cells; that could heat up the battery pack and lead to very unlovely effects like the battery going up in flames.
Like I said ... tinkering around inside the tablet, or with its battery, requires some SOLID, and SERIOUS, knowledge about electronics (i.e. Ohms law to calculate a suitable current limiting resistor value).
Anyhow, attempting Adam's trick (applying a "dummy load" resistor across +5V/GND to get the charging circuit to charge the battery) or pre-charging the battery might be the only way left to get the tablet back to operation - unless he wants to fork out some cash to obtain a replacement battery. Though, with a somewhat charged up replacement battery the "life saving" attempt should well better play out at the first attempt to at least get a recovery up and running (the tablet actually charges in TWRP, can't say for PhilZ/CWM Swipe) or have the tablet get into download mode (once connected to the PC it should draw power from the USB and leave the battery alone).
Though... on a second thought... shouldn't the tablet charge the battery with a lot less than 5V? Looking at the image of a replacement battery on Amazon it would seem the max. charge voltage is 4.2V (this may even involve a voltage divider to bring a 5V supply down a bit).
Typically you can charge a battery with a slightly hotter voltage.
.8 volts isn't that bad a car can charge at 14.4 volts for a fast charge (normally 13.8 tho)
I would charge it from a 100 ma USB charger till it hit 3.7 volts but then again I'm the guy who burned up his rc car....

First of all I'm very grateful for the concern and more grateful for the knowledge that u shared. i tried to remove the battery and putting it back again, guess what it did'nt work. :silly: I know I'm such a klutz for not reading all about this new OS, because i have done flashing a couple of times before with older versions that's why i felt confident in flashing this new one. I truly feel like an idiot now hahaha... Hope that it would turn on again even if only in the download mode. (Wishful thinking...)
Thank you again for the info, idea, suggestion, etc. etc.. :good:
I have a question. Do you think i accidentally destroyed my battery in my attempt to bring my tab back to life? I just drained it after reading a thread that says "drain the battery and charge it again". Is it the battery or did i just hard bricked my tab by being a complete idiot
btw isn't "Adam's trick" similar to the so called JIG method where you solder resistors/resistor to a micro USB plug? (I'm very sorry for my lack of knowledge, I'm just a medical student with a knack of tinkering with devices
@Nirdla01: To answer your posts from above...
About "was flashing ROMs before":
There's the trap. Each device requires a different strategy to prepare it for flashing a custom ROM; it's not as straightforward across devices - even within the same vendor - as you may think. The other trap, which isn't obviously clear from "just reading through the <insert name of ROM here> OP post" is that the more recent ROMs require an updated recovery for successful flashing.
To wrap it up:
CWM 6.0.2.7 is to be used with CyanogenMod 10.1.2 ONLY
CWM Swipe Edition, Philz Touch Advanced CWM Recovery and TWRP are to be used with CyanogenMod 11 or OMNI
TWRP is to be used with OMNI (with the official Nightlies it's even required so you can flash the nightly delta updates, to my knowledge CWM does not support the "OpenRecovery" scripting).
CWM Swipe Edition, PhilZ Touch and TWRP are all provided by AndroidAndi through his file repository on AndroidFileHost.
As for "destroyed battery":
No, I don't think you "destroyed" the battery. That's not easily doable. However, if the battery is deeply depleted the charging circuit may not want to start charging because it has to pull a whole lot of current (current = Amps). Normally a properly designed charging curcuit shut down in case it goes over-amp to prevent damage.
What I don't fully understand is that you can't get into download mode, though you said the tablet will at least show you the red "Battery Empty" screen for a brief moment.
Anyway, disconnecting and re-connecting the battery doesn't help you in any way. I would try to get some juice into the battery by using a silicon diode (that are the tiny diodes with that copper/brown glass body and the black stripe on one side denotig the cathode) in series with the +5V line coming from the power supply to drop the voltage to ~4.3/4.4V and let it try to charge for... let's say 30 minutes for a start while also keeping an eye at the temperature of the battery (just touch it every one or two minutes, and if it gets too hot to the touch (~ 122°F/50°C) disconnect the power supply and let it cool down if the 30 minutes aren't up already). BUT... Do NOT use any power supply outputting more than 500/750mA for safety reasons! Once you charged for some time connect the battery to the tablet's motherboard and see if it shows a change in charge (i.e. slightly green instead of red). If that works just charge it up a bit more until you're at ~50/60% charge.
Then prepare ODIN + Stock image or ODIN + custom recovery and see if you can get into download mode to flash (avoid having the tablet turned on for too long to save battery - once it's connected to the PC and flashing it draws power from the USB anyway).
If that does not work out no matter what you try, because you managed to screw things up really good, using a JIG to flash through JTAG is then your last resort of recovery (if you can get hold of a readily-assembled one or are able to build one yourself).
As for the confusion about the resistor. I wasn't referring to a JIG. I was talking about putting a resistor (possibly 10 Ohms I would assume) across the positive and negative pins of the pins where the battery connects with the motherboard (and while it's connected). That acts as a "current limiter". In this case the battery can't attempt to pull too much current, therefore avoiding the charging circuit from shutting down.
If you have any questions feel free to ask.
@BoneWithABeagle: Thank you for entertaining my questions you've been a really good help in my journey to revive this piece of brick :laugh: I'm sorry for asking these silly questions, as you know I'm not that knowledgeable about electrical stuff, and I find your advice and suggestions very helpful. So here's another question Can I use the usb cable maybe cut the part where the plug goes into the tablet and maybe connect the wires of that cable to the wires battery directly, then plug the cable into the adapter then try to charge it?
to give you an idea I uploaded some pics :fingers-crossed: btw please view the photos in another tab to see them fully because I've put red arrows as guides.

Not a terribly great idea for two reasons: The charger you got with the tablet will happily output up to 2.1 Amps... that's a whole lot of current and far beyond any safe attempt of trying to "hot charge" the battery to reinstate a basic charge. The other reason being the leads inside the USB cable. You cut them rather easily while stripping the outer insulation, but if you got a replacement cable in case the repair attempt works out have a crack at it.
So, while you can sacrifice the cable if you don't have anything better at hand, I highly recommend you to either use a power supply being limited to a much lower output amperage (5V @ 500<->750mA - you don't have any old phones?) or to torture Google to work out a suitable resistor to limit current from the Samsung charger (again, should be large enough to choke current down to 500<->750mA). Also be aware that a limiting resistor needs to turn quite a few Watts into heat. Layman's Estimation Formula: Volts * Amps ~= Watts. Burning away 1.35 Amps to bring it down to ~750mA ... the resistor has to turn ~6.5W into heat, and that's a lot even if it doesn't sound like much! So you need a ceramic power resistor which will get very hot to the touch (keep that away from things that easily melt). Every well-equipped electronics store should have such a such for some exchange money.
