I have a new issue with my backlight. I didn't really see anything scanning a search on backlight so I'm hoping someone has seen this before and can help.

I just got a new 3200mah battery. Ever since I started using it, after turning off the device, I go back to it, press the power button or backlight button and while the screen itself comes on, the backlight does not. No light at all. I also often find that the screen is on already when I open the phone (which might explain why my battery is sometimes finding itself dead in a matter of a couple hours). I change the backlight setting to be the second tick on the scale (lowest light level) and turn the phone off again and then if I go back to it 5 mins later it's gone back to the first tick (off) on its own. However, turning on the phone right after I turn it off and it stays at the first tick. I've not be able to figure out why it keeps resetting itself to off.

Please, if you are familiar with this can you offer some direction? I'm using Helmi's WM6

Thanks

I never encountered this problem.. have you tried to keep pressed the power button and verify that backlight turns on? Or is a settings problem (backlight settings turn itself automatically to zero)?
[JASJAR, XDA Exec, MDA Pro ROM Development] Timeshell:
It 0's itself. I can turn it back on again with a little difficulty (as it's hard to see the screen without the backlight).
[JASJAR, XDA Exec, MDA Pro ROM Development] indrastrid:
really weird ...

have you try back to use the original battery? just for check is it something wrong with your 3200?

if it still ... (also for all problem that i can not solve) ... backup all data and ... hard reset!! :D

Backlight fixed with new flash...battery problem now

Ok, I reflashed with the Business rom and the backlight issue is gone. However, I have another issue now. When I charge it overnight, in the morning the power light is green, but if the Universal is off when it goes green it seems to hang and I have to reset. If the Universal is on, it responds fine. However, in both cases, when I unplug the power from the Universal, the light stays solid green and requires a reset to show the true battery status.

Also in both cases, after this overnight charge, the battery dies within an hour or two, the power level going down to 4%. As a result, I end up charging it at work (with a different charger) until it gets to 100%. I haven't tried leaving it to charge longer. But once charged on my work charger it seems to discharge properly without dying in an hour or two.

I'm very perplexed by this situation. Is this a battery problem, charger problem, phone problem? The battery, as I mentioned earlier, is a brand new 3200mah. Should I return for an exchange? I'm looking for any comments at this point. :confused:

Battery

Hi,

The locking up could be down to the overclocking/stepping built-in to some of the newer Roms. Some Uni's over/underclock quite happily some do not. Mine will happily overclock but locks up when stepping back down.

As far as the battery/charge issue it could be the battery itself or the charger, when charging at work are you using USB to charge and mains at home? It could be that the mains charger is charging too quickly for the battery to hold the charge and the device reads the battery as 100% and thus stops charging it, whereas the USB trickle charge is slower and thus the charge remains for longer.

Do you have another battery to test?

It could simply be the battery, there have been a lot of reports of Ebay batterys not reporting and holding charge correctly.

Cheers,

Beasty
[JASJAR, XDA Exec, MDA Pro ROM Development] Timeshell:
Yes it is an eBay battery. The charger at work is a "main", however, not an original "main", but its also an eBay special. The original "main" at home was designed for UK but I'm in Canada so there's a voltage difference but within the tolerance indicated on it's input definitions.

I'm however inclined to agree with the "trickle charge" comment. It could be charging more slowly. And I have not left it to see if the charge light will lock on green after the charge. I'll try that during the day and charge overnight with the work charger to see if I get the same result.

I'm still open to more comments.

I have problems with upgrading from B830 to B853. Every time I try to update, it just ends up in TWRP and I will just have to reboot.

I downloaded the update.app from http://consumer.huawei.com/de/support/downloads/detail/index.htm?id=58465 hoping that would work. I have also tried downloading it using Updater (only 70MB there) but the result is same. I thought it would be a fast update for better performance, don't really want to do a clean install at this moment.

Any suggestions? Has anyone had the same problem?

via local update it is not a clean install..by force update it will be a clean install (what i recommend, and after update a factory reset)..

the upgrade to the mate s is worth it, better performance, more features, brighter and clearer display, btw bigger ;)

[G4 Q&A, Help & Troubleshooting] :
Afternoon all,

My G4 has hit the bootloop for the last few days. Periodically, it has powered up to the main screen, but not for long enough for me to recover data.

I just spoke to a data recovery place that told me that if I can put my phone into download mode, they can recover the data. Lo and behold, my phone is currently next to me in download mode!

I'm quite keen to avoid dropping that amount of money if possible, so does anyone know of a way to recover the internal memory of the phone via download mode?

Apologies if I'm duplicating a previous thread - I had a quick look, but couldn't see any with the same issue.
[G4 Q&A, Help & Troubleshooting] s0ulreaver:
Probably when the phone is in download mode they can copy the partitions bit by bit then try to do data recovery from those partition images.

So if the phone doesn't boot, it doesn't mean the data partition is corrupted so in theory you could try to copy the data partition and mount it and see what files you can recover.

I do not know the exact commands to dump the data partition but I think that's the way it can be done.

Anyone else willing to give a hand here?
[G4 Q&A, Help & Troubleshooting] :
Thanks for the help so far. I believe the data is intact - when the phone starts up, the data is all there. It's just accessing it that is the issue.
[G4 Q&A, Help & Troubleshooting] je2854:
something similar to

dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/mnt/media_rw/external_SD/data.img

OR

dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/dev/block/mmcblk1/data.img

don't quote me on that but in theory this should work...

make SURE you have a 32gb SDCard in the phone first
[G4 Q&A, Help & Troubleshooting] :
Where would that command be entered mate? Sorry, only ever used my phone stock before.
[G4 Q&A, Help & Troubleshooting] je2854:
I thought the OP title said download mode?

Use the LG Root method as if you were going to root..

I'm mobile ATM but if I remember correctly...

Send_Command \\.\Com# [# meaning your com port number]

Then insert that command.

Tomorrow at work I can get a common list of partition names and the command to back it up with.
[G4 Q&A, Help & Troubleshooting] nagalun:
You need to mount the partition first.

Also, you could mount data if it is not encrypted (is it?)

Do this:

mkdir /temp
mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/
[G4 Q&A, Help & Troubleshooting] terisse:
A little tip that should work :

Take the battery off your phone

Put both phone and battery in the fridge

Wait till the phone is cold and boot the device.

The bootloop trouble is due to an abnormal warm so this way you can have a one shot normal boot to backup your data before send for warranty.
[G4 Q&A, Help & Troubleshooting] s0ulreaver:
If you try this, please put the phone in a ziploc bag 1st and seal it so humidity won't get inside the phone while in the fridge.
[G4 Q&A, Help & Troubleshooting] je2854:
just a question though... How can you use this command if it will not boot?

---------- Post added at 08:59 AM ---------- Previous post was at 08:50 AM ----------

to get into download mode do the following...

Pull Battery

Hold Volume Up

Plug in USB Cable (make sure it's plugged in the computer)

Release button after 5 seconds

follow the link to grab the files needed for "Send_Command"

Grab LG Root here

once you are in the mode and you followed directions you can copy the command I wrote

above to copy your data partition. The reason you must have a 32gb+ SDCard is you will

be making an exact copy of the /data partition where you can remove the SDCard and recover

whatever is needed.
[G4 Q&A, Help & Troubleshooting] nagalun:
Hmm... With the Send_Command.............? dd is a command too :silly:
[G4 Q&A, Help & Troubleshooting] je2854:
there is no need to mount the partition first..

the dd command will copy the partition as a RAW image.

you must then take it to a computer and mount it as an EXT4 or use it with ext2explore
[G4 Q&A, Help & Troubleshooting] nagalun:
in that case the command you have given him will copy 4492 mb only.

Here is why:

dd if=/dev/block/mmcblk0p55 bs=8192 skip=65536 count=548352 of=/dev/block/mmcblk1/data.img
input_file=(some partition) block_size=8192 skip_this_much_data=65536 how_many_data=548352 output_file=(somewhere)

actual data copied is 8192 * 548352 = 4492099584 bytes, and you are skipping some data from the beggining with 'skip'

you do still need to mount the sdcard, the "mmcblk1" is not treated as a directory, and it is very unlikely the sd card is mounted automatically in download mode.

[G4 Q&A, Help & Troubleshooting] :
Hi all. Firstly, thanks for all your responses!

I've not got much of a clue what I'm doing unfortunately, I've never really messed with Android before - I'm typically fairly computer literate, but I've steered clear of messing with and rooting phones for the most part.

So to clarify, I've downloaded LG Root, Running either of the exes just leads to a cmd box that's open for about a second before closing, so I'm presuming I've missed a step. Is there a guide already in existence on how to use it?

But once in, ensure there's a sizeable Micro SD card in (it's a 64gb so I should be okay!) and use the send_command exe to send:

mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/

And then the entire image should be on the Micro SD card.

How would I then mount the data image to be readable? I've only used .iso for mounting before.

Apologies for my ignorance - I'm probably making helping me quite difficult!
[G4 Q&A, Help & Troubleshooting] :

[G4 Q&A, Help & Troubleshooting] IlyaKol:
I'm having the same issue and actually tried this earlier today. Ports.bat didn't show a DIAG communication port even when I had the phone stably sitting in Download Mode.

Going to try the freezer trick. I already bought a Nexus 6P, just want to unlock the locked content on my SD card. lol.

EDIT: Holy crap! It worked. I chilled it in a baggie, then stood in front of the freezer as I unlocked all of my locked gallery files (1,411 files totaling 900MB). As soon as I was done, 30 seconds after stepping away from the freezer, it started to bootloop again.

Got the only information I needed off my phone...nice! I might give it another go tomorrow and see if I can't run ROM Toolbox and backup all my apps so it'll be easier to push to my N6P.

Awesome suggestion!

Hi all, sorry for the double posting, but just to make certain before I do something that will accidentally brick my phone. I'm intending to do the following:

Put phone in download mode and connect device.

Open LG_Root folder

Run a command window in LG_Root

Send_Command.exe \\.\Com4

Then, line by line, command:

mkdir /temp/sd /temp/data
mount /dev/block/mmcblk1p1 /temp/sd
mount /dev/block/bootdevice/by-name/userdata /temp/data
mkdir /temp/sd/recoverydata
cp -R /temp/data/media/ /temp/sd/recoverydata/

Once I've done all this, what happens next? Will I see responses on the screen etc?

Again, I apologise for the probably stupid questions. I don't want to brick my phone and lose all of the data, but I'm going away with work so would like to square it before I go if I can.

Many thanks to you all so far.
[G4 Q&A, Help & Troubleshooting] nagalun:
Do "mkdir /temp" as the first command, then the others in order, also you need a sdcard.

If you want to make sure it worked, before doing "cp -R /temp......", do

ls /temp/data/media/0/

You should see your files and folders, and if you do

ls /temp/sd/

You should see the files in your sdcard. if everything is correct you can start copying with "cp -R /temp..."

If you see errors making the directories that say: "Read-only filesystem", do this:

mount -o rw,remount /

Then try again.

You will only see responses if a command fails, if not, it will not say anything.

After the command cp has been completed, do "sync" to make sure everything is written to the sdcard and then you can do:

umount /temp/sd
umount /temp/data
[G4 Q&A, Help & Troubleshooting] :
Doesn't appear to have worked unfortunately. I haven't checked the SD card properly as I'm now away with work, but when I ran ls /temp/SD there was only the recovery file listed - and nothing on the /data/media/0 command. ?
[G4 Q&A, Help & Troubleshooting] nagalun:
please note that the commands and arguments are case sensitive, also you mounted data on /temp/data/ , not /data/

Hi all, sorry for the slow replies.

I've gone through the commands a couple of times now, and haven't managed to get any output. No additional data appears on the SD card, and only #ls /temp/sd produces a response - 'recoverydata'

Am I missing something that I should be doing?

Can you please tell me which is the company who is able to retreive your data from download mode on lg g4 ? Did you find a way ? Thank you
[G4 Q&A, Help & Troubleshooting] Norcalz71:
anyone found any way to get the thing stable in download mode other than the freezer? mine has been in there on/off for 2 hours and I cant get it to stay on more than 90 seconds or so. is this send command working for recovering pictures from the internal, provided download mode can stay active?
[G4 Q&A, Help & Troubleshooting] Norcalz71:
So I managed to actually get into download mode and recognize via ports.bat. I then ran send_command and issued the following commands as described above (this an ATT H810):

mkdir /temp/sd /temp/data

mount /dev/block/mmcblk1p1 /temp/sd

mount /dev/block/bootdevice/by-name/userdata /temp/data

mkdir /temp/sd/recoverydata

cp -R /temp/data/media/ /temp/sd/recoverydata/

Trying to understand what it's doing and make sure I'm doing it right:

1) making directories /temp/sd and /temp/data - are those on internal storage?

2) mounting block mmcblk1p1 to /temp/sd directory

3) mounting not sure what to the /temp/data directory

4) making another directory /temp/sd/recoverydata (again is this on internal storage or external)?

5) copying /temp/data/media to /temp/sd/recoverydata (again not sure what this is doing)?

Is that mostly correct above? All I really care about are my photos in the DCIM folder, so if I could direct straight to those to reduce copy time and reduce the risk of it rebooting again that would be ideal. Do I need to mount the SD card first? I'm not sure where it is creating those directories (very noob at linux anything). I tried executing those exact commands above and nothing seemed to happen - should it be an instant copy (I doubt it) or will it take awhile thinking and copying files over to the SD card? My guess is it takes quite awhile since its GB's of stuff, but not sure my phone will stay on that long.

Since I managed to actually get into download mode I hope I can recover my photos (any method at all would be fine even if complicated as long as I can get them).
[G4 Q&A, Help & Troubleshooting] Norcalz71:
is mmcblk1p1 the external SD card, and you are mounting it to the directory /temp/sd which you created, and then copying /temp/data/media/ (which is the userdata block mounted to this location) to the /temp/sd/recoverydata directory (which is the mount point for the external SD)?

Is that correct? I'm just not seeing where the external SD card comes into play in those lines unless mmcblk1p1 is the partition of the external SD for the G4.

major fingers crossed I can get this to work.
[G4 Q&A, Help & Troubleshooting] nagalun:
(Read the end of the post first, please)

Yes, that is exactly it, the "p1" is the partition 1 of the card, also I'm not subscribed to this thread so I didn't see your last posts.

You should mount the rootfs (/) read write before doing all that:

mount -o rw,remount /

I'm not 100% sure if the send_command is a proper shell or if it doesn't work for some tasks, if something fails you should get an error explaining what's wrong.

After making all the directories and mounting you can run the "mount" command to see which partitions are mounted. You should see something like this:

rootfs on / type rootfs (rw,seclabel,relatime)
/dev/block/bootdevice/by-name/userdata on /temp/data type ext4 (rw,other_unimportant_options...)
/dev/block/mmcblk1p1 on /temp/sd type vfat (rw,blahblah...)

Doing "ls /temp/data/" should give you the usual folders you see from android: app, media, misc, system......

Copying may take some time, and if the shell is proper you should not get the "#" prompt until it is done.

---------- Post added at 10:25 PM ---------- Previous post was at 10:12 PM ----------

1) those directories are in the ram, they are not persistent.

2) it should be the external SD

3) the partition that contains all the user apps and files

4) Now this folder is made on the SD card, because you mounted it to the /temp/sd directory

5) It is copying the entire internal sdcard to a folder named recoverydata on the external sdcard.

I think you could do this:

cp -R /temp/data/media/0/DCIM /temp/sd/recoverydata/

To copy the DCIM folder only.

This here ↓↓

I just checked and I'm sorry, the data partition gets automatically mounted.

instead of mounting userdata and copying from /temp/data, do this first:

mount

and check if the mmcblk1p1 is already mounted and where, then for example if you see:

/dev/block/mmcblk1p1 on /external_sd type vfat (rw,blahblah...)

You replace the "/temp/sd" bit to wherever the directory is:

mkdir /external_sd/recoverydata
cp -R /data/media/0/DCIM /external_sd/recoverydata/

(No need to mount if everything already is.)
[G4 Q&A, Help & Troubleshooting] Norcalz71:
Major thanks, going to have to digest that a bit. I just want to make sure I'm 100% clear on what the commands I run are actually doing so I can speed through it when/if I can get into DL mode again. I only got about 2-3 minutes last time before it looped, so hoping I can fly through it if it turns on.
[G4 Q&A, Help & Troubleshooting] nagalun:
If you have time after copying and want to make sure everything is well written, do the command "sync", this will write all the cache and things in ram so if it reboots there is no chance of (major) corruption, it will still shut down without unmounting it first, but nothing should really happen from that.
