Used One X, boot loop then out of battery

Hi,
I really truly tried to resolve my issue (by searching etc.) and learned a lot along the way but I have the problem still.
I bought a used One X. The guy showed me Jelly Bean working on it. I didn't use it at the sale. After I got home I found it was stuck on the HTC start screen. I had to go and it wouldn't turn off so I left it for half a day.
Found the volume down and power trick and booted several times into recovery mode and clockwork. Eventually tried format SD in clockwork. I also found a factory reset or similar button somewhere (can't quite remember if it was in recovery or clockwork). I think it was then that I had no more clockwork. Got a loop into Fastboot, message at the top says "Relocked - Security Warning". Can't switch it off. It occasionally switches itself off doesn't respond to the power button, after a few minutes with a usb plug in it starts again. It turns itself off after 15-20 mins again. When in Fastboot all options just loop back to Fastboot although reboot bootloader takes more time and has more lights.
Eventually started using fastboot cmd. Got an unlock token to flash, received error Failed (remote: battery low). Continued to receive that error with whatever I tried.
Found forums on using wires on the battery to charge and cycling reboots without success. As far as I can tell you can't get to the battery of the one x and I don't get the HTC flash screen mentioned in the cycling solution anymore.
Can I charge this phone? Should I investigate taking it apart to access the battery? Will a phone shop be able to fix this problem by doing things I can't?
Thanks for your time.

Great! Thank you very much A&D. I downloaded and installed Android SDK, got the file and put it in the right folder, now I need to open a cmd window and type "adb ???? fastboot-battery-recharge.bat" in order to charge the phone. Can you help?
Thanks

Just extract the Fastboot-battery-recharge.bat and put it into your platform-tools folder inside your Android folder (assuming you have downloaded the SDK).
Now enter fastboot (power and Vol Down) and double click the .bat file and let it do it's work
Another source for you

Great thanks, it's going. I didn't realise it was a batch file.
One problem is that my voltage is going down not up, happy to leave it for a while though. Started at 2877mV and now is 2858mV after about 50 cycles. You can see it going up sometimes and down others but overall is going down...
IMPORTANT: I figured out you need to use a short usb cable and avoid front panel and bracket usb slots

Weird. Your phone is still connected right? It should be charging but takes a long time. If all else fails, HTC is your only help ):

Hi,
I have the same problem but i can't get ADB to work on mac osx.
I can't get to recovery because the battery is to empty, i can't get to flash a boot.img because batt. is empty.
does anyone have a solution?

The battery is up after 30 mins to 2960mV so it does work overall.

The batch file contents are as follows:
@echo off
:start
fastboot getvar battery-voltage
fastboot reboot-bootloader
ping /n 6 localhost >nul
goto start
You could write your own batch for use with mac (assuming mac's can run fastboot.exe)...or just type it out for 6 hours straight

I have the same problem, the HTC screen is coming up the led is burning and than reboot (in about 5 sec).
My Battery is charging with every reboot very slow but it is charging.
From 1% to the required 3474mV was 12 hours of charging (about (8640 reboots :silly
Now i am on 3487mV but this is still not good enough.
I will let is charge for a little while hoping it will work again.

Solved - "FAILED - Remote (battery low)" error

Yep it's a common problem by the sounds and hopefully this thread will stand out as the one to use.
Basically if you receive a "FAILED - Remote (battery low)" error through fastboot you should use the command "fastboot getvar battery-voltage" and find out how far from the required 30% (how low the mV number is / highest mV the battery holds = [> or < 30%]), this will vary from phone to phone. If you are under the threshold and have the older boot loader you will not be able to charge your phone by leaving it plugged in and hoping. You are have 3 options:
1) If your phone has a removable battery you can the wiring from an extra usb cable in order to get charge or just put in a charged one - the One X cannot use this solution
2) If it is close to 30% you might be able to get enough charge by rebooting it 10 or 20 times (this is because for a portion of the boot up time the phone takes on charge). The report of this solution working involved the ph boot looping onto the HTC splash screen, my ph was looping into boot loader only.
3) If it is far enough off the correct mV, you can run a batch file (props to Laav) that loops 2) and reports battery voltage until you are satisfied. This requires a USB connection and you should use a short usb cable and avoid front panel or bracket slots (especially if you notice that the voltage doesn't always increase each reboot).
Once you get to 30% you are able to flash imgs using fastboot and I would recommend (as Laav does) flashing the newer Clockwork Recovery which allows you to charge the phone while in recovery mode. Then let it charge to 100% and worry no more that you'll get caught out.
If you are reading this and don't have this problem, make sure your clockwork is up to date so you don't end up with it (ie. having a problem with your rom and needing flash tools with a battery below 30% leaves you with no way to charge it).
From my experience the batch file method increased my battery voltage 300mV in about 3 hours so 100mV/hr is probably a reasonable guideline.

I'm sorry actually it's not working for me. Just checked the voltage and it's 2960mV. Because it's not my phone I don't know if it had a battery problem or anything. Is there no way around the 30% check?
The receipt says it was purchased on 24.4.12...

This tutorial thread says 30% = 3478mV
With battery-voltage: 3490mV
sending 'boot' (4466 KB)... OKAY
writing 'boot'... FAILED (remote: battery low)
Others say it has to be over 3680mV, i think this is the correct value. But i don't have that value so i have to wait until then to check.
I have the clockwork recovery but it is not loading, when i press recovery i see the clockwork logo about 1 sec and then it reboots.
For now i wil leave it to the charger for 7/6 hours and let it reboot every 5 sec, i hope this will get me enough power.
Is there someone who can make the batch work on OSX?
Thanks

2819mV now...2781mV 3 mins later... I guess aside from installing a new charged battery or sending it to HTC I'm sunk. I'll call a phone repair store and see if they'll change the battery and flash the new clockwork or stock rom for me tomorrow...
Does anyone suggest a change to the batch file/timing to see if that works? To make it longer do I change the "ping /n 6 localhost >nul" to a larger number?
Are other people getting a constant increase when they look over the voltages reported?

OMG! I found something v. important out, I was using a long usb cable (1.5m) and a usb slot on the computer that is a bracket (rather than the motherboard slots) and once I changed over to a very short cable (10cm - I have it for the car) and the motherboard usb slot I'm almost charged up in 10 mins. I'll edit the longer post now.

Received error "FAILED: remote (not allowed)" when trying "fastboot flash recovery recovery.img"

If your bootloader is unlocked, just flash CWM touch recovery whilst the phone is in fastboot.
http://db.tt/VF9J2eo8
Place it in the same folder as fastboot in Android SDK,
Enter fastboot
Plug in usb cable from PC to phone
Should now say fastboot USB
Open command prompt
cd c:/Android-SDK/platform-tools
fastboot flash recovery CWM.img

A couple of hours later my battery did not charge ant more and is stuck at 3490mV.
Is there any other way to load my battery?

You should still be able to flash ClockworkMod & a custom rom.
You could do this, even if to at least get your phone up and running to charge it fully.

I found the same thing, it wouldn't go past this but it was enough to change the message from Battery low to (in my case) Not allowed.
I had locked the bootloader but it wouldn't unlock so I locked it (sent command twice and received 'ok' message). Unlocked the bootloader again, realised how the menus/options on stock bootloader actually work, loaded clockwork recovery through the recovery option (it was on there the whole time), went back out and made sure it was up to date, used it to install a new Jelly Bean copy, charged the phone.
Well, it took 12 solid hours of researching and attempts after I initially bought what was supposed to be a working phone but it's back again.
Thanks to all who contributed to my questions.

[Q] HTC not charging and booting up.

So, yesterday i was flashing first rom for my HOX and it seems it had less battery than 30% and it wasnt done flash rom completely and it is stuck in "HTC" screen and Bootloader says, that there are "Battery level is too low to flash" .... So what i can do now? How I can do to it does work?
How to charge it?
P.s. In Fastboot my computer is not recognize my phone and I cant go into recovery - because it boot in to it and automaticly reboot my device.
++++++ SOLVED - for solution read #8 POST ++++++

it's a well known problem, don't try to charge from usb cable. power off and plug it into the wall charger and leave it charging for about 3 hours or more

I can leave it on HTC screen?
I tries this -
Code:
@echo off
:start
fastboot getvar battery-voltage
fastboot reboot-bootloader
ping /n 6 localhost >nul
goto start
But still it not let me in into recovery ...

No, power off completely and plug into wall charger for at least 3 hours

How do i do that? After i power it off (I cant go further than HTC logo and in Bootloader it do the same) he switches off and then starts again and boot till HTC logo ...
P.s. I hold Power button - it turns off, conect to wall charger, red led indicator shows up (in front grill) and after ~5 sec it automaticly turns on.
P.s.s. It turns on only with charger in phone ... w/o charger it stays off.

red led is on, phone comes back on, does the led stay on on wall charger ?

Yep it was on, but full brightness screen ate more energy than changer can give, so phone was discharging.
Problem was this -
Phone was not able to boot up ROM, because there was no energy to flash full rom, flashing failed - not fully flashed rom, so no system to operate;
Pc di not recognize my device, but somehow it still was able to flash from sdk;
When i tried to boot into recovery, it just blinked and rebooted phone.
So what i done -
Pluged my phone via usb to my pc;
Navigete to fastboot, it was showing fastboot USB;
Opened sdk -> platform tools folder, created txt file with code (below), renamed <name>.bat
Code:
@echo off
:start
fastboot getvar battery-voltage
fastboot reboot-bootloader
ping /n 6 localhost >nul
goto start
Runed my .bat file;
Script was runing and phone was turning on, then off, on, off ... etc, so the voltage went to 3680mV, somehow not further;
Closed my .bat file ...
Navigated to recovery, boot it, still NOTHING;
P.s. I was using that from General theard "All in one kit for HOX", but seems antivirus was deleted something and i flashed faulty recovery;
So I downloaded new one CRW;
Flashed it - "freeboot flash recovery <name_of_recovery>.img" form sdk tools...
So - it was booted into recovery,
Went to mound storage, but it was not alow me to mount it, some kind of error,
I flashed - TWRP - from rondom sorces;
There I was able to mount storage, put ROM in storage.
SO I Wiped and Format all what neceseary and get back to PC;
There I flashed boot.img via SDK fastboot tool;
Then from recovery i flashed my new ROM;
DONE! That was so hard, but only thing what was foult was recovery and my unclever mind to know it before - but as they say - "If you are not tryed it, you will never know how to do that" ...

Desire HD bricked!

Hey guys,
I've flashed quite a few ROMs in the past 2 years. Today, I flashed a new ROM and it worked fine. After that, I installed Nova Launcher and changed the density to 160 and the phone asked for a reboot. However, it isn't booting after the reboot. I can see the white HTC screen for 1-2 seconds, after that the display dims and then turns off. Can't go into the bootloader or the recvovery. The phone charges normally (can see the orange light) and on connecting to the PC, it gives the successful connection sound. Any tips on how to fix this? I've done S-OFF long back if that helps. I've tried removing the battery and inserting after 5-10 mins, however I'm still getting the same output.

EDIT: Guys, just noticed that the phone isn't turning off after the HTC white boot screen. The backlight starts and then turns off after a second, and then starts again for a second and this keeps repeating..

Pull the battery.

Did you reboot holding power and volume-down?

Yeah, tried all possible combinations incl the usual power + vol down. The HTC logo appears for 5 seconds and then I can only see the backlight on the screen for another 2 seconds. This backlight then turns off and turns on repeatedly every 2 seconds and continues till I remove the battery again.
In short: No bootloader access, no recovery access. Just can see the device after I connect it to pc and type adb devices.

UPDATE: Fixed. Used the adb, on typing adb reboot-bootloader, I could access the bootloader. Thanks guys!

Same problem, Please Help!
My DHD, passes the HTC logo, then goes blank. The backlight doesnt go off, its just blank and remains like that indefinitely.
There is no charging led light when on the blank state,
The blank state does get detected by the computer.
Fastboot Commonader V1.51 says no fastboot device detected.
(P.S. My volume keys are water damaged and do not work, so i cannot use Vol- and power)

just try plug your phone to pc...then open cmd n change source to adb folder that you place..then type "adb devices" if your phone detected in there..then you can continue to next command type "adb reboot bootloader" or "adb reboot recovery"..next if you success go into recovery..just flash/ install another rom from there..
hopefully can help...

That worked. Thanks

M9 issues after update

Hello everyone,
a friend of mine is having problem with his M9. He recently downloaded an update to the phone, but after restart the phone no longer boots, says 0% battery and would not charge (just keeps heating). After a while on the charger it tries to boot (white screen with HTC logo), but after like 20 seconds it reboots.
I can make it enter the "service menu" (or how is it called) - white screen saying "Software status - modified, LOCKED, S-ON" and some menu items (I would post a picture but the forum won't let me because I am new...)
the problem is that Recovery mode does not work, there is just black HTC logo in infinite reboot loop. Reboot to bootloader just reboots to the same menu. The download mode basically says "Failed to boot to download mode. This build is for development purposes only..."
If I plug the phone to PC, while the menu is present, I hear a sound that is was plugged to PC, but a second later it's unplugged, so I was unsuccessful trying to make some sense to it using ADB.
Can the phone be saved? Thanks for help

Whats annoying is that the phone keeps rebooting until it runs out of battery power, I haven't found a way to prevent it from rebooting. So-called "smartphone"...

I tried to update the firmware using RUU_HIMA_UL_N70_SENSE80_ATT_MR_NA_Gen_Unlock_4.23.617.1.exe, but it said I don't have sufficient battery charge. So I plan to use the Fastboot-battery-recharge.bat overnight to give it a charge.
The problem however is that the command
Code:
fastboot getvar battery-voltage
returns "battery-voltage: " without the voltage itself. Anyone experienced this? I am using the latest minimal ADB and fastboot (1.4.3)

BTW the phone is originally EE UK.

Battery problem ? Bootloop when battery unplugged, flash LED when plugged, fastboot ok

Hello everybody,
I have a problem with my Xiaomi Mi A2 Lite (with bootloader unlocked but stock ROM) : I changed the screen and digitizer, the phone being okay after a repair and working for a few days. Then it stopped turning on when I press power button (the screen does not turn on). When I plug charger I have the white LED flashing but nothing (even after hours of charging with different chargers and USB cables). I can not go to fastboot by pressing power button down.
I disconnected the battery, the phone starts when plugged into charger but bootloops (with "Your device software can not be checked" and the fixed "android one unlocked" screen). When I replug battery in the bootloop stops and we get back to the black screen/flashing LED state.
I can go to fastboot mode when pressing volume down with battery disconnected, I tried flash_all from the official daisy_images package with no success. I also tried to fastboot boot to TWRP but I get a black screen (with bootloop if battery is unplugged).
I also tried QDL flashing of the official ROM using the guide on the forum, no success either.
I tried swapping the battery for a new one, still doesn't work.
When I dump fastboot vars I have amongst other "battery-soc-ok: no" (with and without battery plugged) and a reported battery voltage of 1000 with battery, 0 without.
I measured (with a voltmeter) the voltage between + and - pins of the battery I have 4.13V.
Would you have any idea of something to try ?
Thank you for your help,

any updates on this?, my unit is stock no reimage or what not but while charging one time it wouldnt turn on white LED flashing also but no display, so i let be , then after awhile i discovered it wont boot up, after several times trying ,i got to boot but went to be stuck on "android one unlocked" screen, i tried draining the battery same results , wtf is wrong with this phone now it works perfectly for the past 3-4 years

I swapped the motherboard and it worked again.

damn, where did you purchase your motherboard? and did it erase the files inside?
