Need huawei help. - Huawei Developers

So ive got huawei mediapad t3 10. I know it doesnt have a lot support here in xda but ill ask anyway. So thing is i installed it in my car. Unlocked it, rooted it and then i got warning screen at boot. Then i edited some kernel files so it will do like a double boot when power comes on so ill get past that warning screen (then the battery charging screen wont come on and boots into os directly). Now ive got another problem. It discharges when i use waze or any app that has screen turned on. Tried with huawei p30 dast charger at wall socket but it still discharges. Is there any kernel modifications i can do to prevent that? Thanks in advance ??

[Q] X10 mini pro bricked - help?

Hi all,
It seems my X10 mini pro is bricked.
Briefly: When I turn on the phone, it vibrates. About 8 seconds llater, the screen lights up, but doesn't show anything, then goes dark again. It then keeps repeating this: once in a while, the screen lights up, but shows nothing, and then goes dark again.
When plugged in to charge, the LED light doesn't come on (and actually hadn't for a while when charging, even though the phone was still working).
I've deleted all the contents of the SD card and updated the firmware with SEUS and PC Companion; both don't come up with any errors and claim everything has been installed, but there is no change in the phone's behavior. Also tried to install the French stock ROM (the only link that seems to work in the Flashtool+ROM thread) using Flashtool, but to no avail.
Does anyone have any other sugggestions?
I was wondering whether it could actually be a battery problem, as I've had some issues with charging the phone for a while before this happened; e.g. the LED didn't work when charging, and on more and more occasions the phone didn't seem to charge when plugged in. Could this be caused by a problem with the battery? (Have ordered a new one from ebay, so will see what happens when it arrives.) I'm not aware that I did anything unusual with the phone software-wise that could have caused it to be bricked. (Phone was rooted, but I did that ages ago.)
Many thanks for your help!
could be the battery going bad since you mentioned you have it ages ago or so. or could be the cable as well.

I've had it for about 15 months. Is it normal for the battery to go after that amount of time?
Which cable do you mean?
i cannot really tell about the battery but the usb cable for your charger.
Ok, it's not the battery. I tried it in a shop with one of their batteries, which worked in their phone, and the phone still won't turn on.
Is there anyone who thinks it could still be a software issue?
Otherwise it seems my options are to send off the phone, which might cost a bit, or to start digging around in the phone myself for a bit. I found a disassembly guide online, but it scares me a bit, since the first step seems to be to lift off the keyboard, and I'm a bit worried about damaging it and about how to put it back. Has anyone else here got any experience with taking their X10 mini pro apart?
Thanks!
Charging issues etc are nornally to do with the dodgy USB port in the phone. Try wiggling the cable at the port end see if you can get it to charge then try a SEUS

No, it wasn't a charging issue.
Took it to be fixed, and it turned out it was the cable inside that connects the screen etc to the low part of the screen.
Now that the phone is working again, I've got to figure out how to get rid of the French keyboard layout that I got onto it when trying to fix the firmware ...
Why not flashing mine in my signature, it's QWERTY! ;-)

[Q] Note 2 won't boot unless connected to charger.

The title says it all. My brothers Note 2 will only boot past the Galaxy Note 2 boot screen if it is connected to the charger. It doesn't matter if it is a USB or wall charge. If the phone is connected to a power source it boots into the system fine, however, once you remove it from the power source it turns off. I was wondering if it could be a bad battery but the charge is showing it at almost 80%. Has anyone ran into something like this before? If I try to boot the phone without it being connected, it sits at the Note 2 screen for about 15 seconds and then shuts itself off.
I'm not really sure but it sounds like the internals of the battery are closing up (shorting). Are you able to get another battery to test and see if it is the battery?
Note 2 - Boots , Loops, No SDS Detected as per eMMC checker on play store

Having same issues
Seems it hardware plus software issue.
Running 4.1.1 Jelly Bean
Happened after installing few games .
Goes in constant boot loop
Can start by attaching power cord only to socket.
With USB attached to Laptop .. still goes in loop
Powerbank is workaround.
Seems to reboot when saving to sd card ..
Will keep posted

The problem, after getting a stock image back on the phone, ended up being a bad battery. The phone wouldn't hold a charge even though the charging image showed otherwise. Once you get a working image on there, try replacing the battery. I ordered an eight dollar cheapo battery from Amazon and it worked like a charm.

I second this. My phone went down Saturday. Thought it was something with CyanogenMod 11, but flashing back to stock did nothing. Replaced the battery, haven't had any problems since.

Thats first thing i did .. checked different battery ..
Battery is fine .. its not battery issue .. atleast in my case ..
i checked for SDS .. my phone has no SDS insane bug either .. though symptoms were same .
I have backup phone, using it.

I can root and all..
But after this booting dont want to brick it ..
So plan to do it via the mobile repair shop
Had same issue. Solved after replace the battery.
I have the same issue right now as well. I was on stock for awhile and used casual one click method, switched between a few roms. Than it started happening after that. So I flashed back to stock on odin and still have that issue. Havent figured it out yet.

I have had this issue and replacing the battery did the trick. I was having issues with the battery beforehand. once the battery showed as being at 17% the phone would start the reboot cycle and not fully boot until it was plugged in.
Have same problem here.....All these started when I replaced my bulge battery. New battery doesn't hold power below 20%. Phone goes off in boot cycle until plugged in a charger
Try to boot on USB/PC data connection
When connected t PC-system will boot to a point. PC indicates new connection then looses it and Note 2 returns to flash screen. Problem start when using corporate email and encrypted data. Works w/o error connected to wall charger. Disconnect crashes system. Flashes screen forever. No diagnostics. Did all SW reboots. Doubt battery, but will try.

Did you ever test a new battery/figure it out?
Mine is doing the same thing I think. I only boots if connected to a wall charger. If connected to PC with USB it will boot to the [T-Mobile in my case] boot screen, connect to PC for a split second (long enough to make the connection sound in windows, then I can't find it) and it stays on that screen. Without being connected to either, or after pulling plug, it turns off.
Same problem here with mine
can't be just the battery because it will stay on w/o charger when in download/recovery mode or if it gets stuck on the Verizon screen.

[Q] Nexus 9 won't boot or even charge

Hello everyone,
yesterday I've been using my Nexus 9 with a bluetooth-OBD-Dongle in order to read ECU fault codes of a customers car, using the Torque Pro-App from Playstore.
After this being done, I put my Nexus on top of my desk, bluetooth and WiFi still turned on, with about 80% battery left. Eventually the next day I came back into the office and wanted to unlock the device in order to check my mails, but there was a bad surprise: The nexus did not react on anything I've done. At first I thought the battery was dead due to some wakelock issue, but I couldn't really imagine that 80% battery charge were gone in less than 10 hours. I tried to boot into bootloader or recovery, but nothing worked. The screen stayed black.
Even after putting in the charger cable, nothing happened, no battery charging icon or something else. Simply no sign of life at all.
Currently on CM12 nightlies and Fire-Ice Kernel.
What do you guys think? Shall I wait a few days until the battery is completely dead and then try to charge/reboot it or send it immediately in and try to get a warranty repair/replacement?
Is there any possibility to fix it or do you think that I somehow managed to hard brick the device?
Thanks
@MrSchaal,
I've never seen a problem like this. And (based on the fact that 72 users have viewed this thread), I suspect that no one else knows what to tell you.
So, my suggestion would be to return it for warranty repair/replacement. Good luck.
@cam30era
thanks for your advice, I'll give it a try.

Mediapad S7-301u starts but not charging

Hi All,
I wanted to turn my tablet on this afternoon, and it did.
Plugged it right in the wall power socket, but after my Cyanogenmod logo, my tablet says it is empty and turns off...
I have charged it now for 2 hours, but still switching off...
I have flashed different roms, including the stock rom, but nothing helped.
Does someone has something to repair this, or is it just a dead battery?
I hope to hear something soon.
Greetings,
Rik
Bump
FYI: The TWRP recovery mode works.
But it says CPU: 0C (zero degrees Celsius).
I can flash any rom, except the stock one...
I can't boot further than my lockscreen, then it says something about the battery is empty, and it turns off.
This keeps cycling until I stop trying to boot it...
Please help me!
Bump
Nobody with a Mediapad that can help me???

No, until now my tablet is still stuck in that loop.
Therefore a BUMP!
Some new information for you..
I bought a new battery, swapped it with the original one - still the same.
I can update the system via sd card, by starting the tablet and pressing all buttons together.
Flashing works fine, it boots until i see the android beginng menu (with language selection etc..) and then it turns off.
The only thing i can see from then on is the red battery symbol, showing low battery..

Damn that the new battery didn't work.
I have got the same problem as you...
You do not have found an other solution??
I hope someone can resolve this problem... :crying:
Make sure the battery plug is connected correctly. After changing battery I had to reopen the pad twice because battery stayed at 0%. It is a bad plug, maybe it can already get loose because your tablet fell of the table.
Also look at the manufacture date of your "new" battery. Mine was from 2011 !!! Surprisingly it works, but yours could be bought dead.

Green charging screen of death?

Hi all,
My phone cut out at about 10% battery charge earlier and wouldn't turn back on. I thought it was probably just bad battery stats. But now I'm home, even after an hour on charge (and 30 mins on another charger) the phone won't turn on. It also shows up as an unrecognised device in device manager.
Whats weird is that when I first plug the charger in, rather than seeing the blue battery logo, I see an unfamiliar green battery logo as attached.
Has anyone got any ideas on how to fix this? (Tried booting with the volume up and volume down buttons held)
It's also come at quite a frustrating time, I may not be able to reply until Sunday night as I'm off camping in the sticks for the weekend.
Thanks
Plug your charger and Try to keep holding the power button for 1 min.....maybe start

Sadly that didn't work.
The battery appears to now be taking a charge (300mA/h according to a USB multimeter), but I haven't been able to even get SP flash tools to recognise the handset sadly.

That is the conclusion I'm coming to, sadly there doesn't seem to be a UK stockist of the battery yet, but I guess in the mean time I can see if the seller will honour any form of warranty on the product. For now, I'm back on my old G3 and it doesn't even begin to compare. I loved my Elephone.
Bad luck my friend.....I have a samsung galaxy 2 and one day run out of battery and never awake again....weird things
I think it should be cover with warranty.....Is one year in China
Type a email to Elephone support and they must be assist you because the phone is less than one year in the marketing.
I hope you will have a possitive news from Elephone
Thanks, I'll let you know how I get on.
I have the same problem a while ago with the green thing logo while charging , I even try it on wireless charger but it has the same thing with the green logo of battery ...but luckily it charge normally with blue logo
I have seen this on my screen a few times when I ****ed my bootloader during flashing. Device ended up being semi-bricked. I could not flash via SPtools because my device didn't get recognized. I was able to fix it luckily!
Hi all, sorry for the delay in responding.
So, the first problem was the battery. You need to charge it beyond 3.8v I think to get the phone to turn on, probably better to get it to 4v so you have enough charge stored to use the phone. The phone can't charge the battery below a certain threshold (around 3.7v) so you have to remove the battery and use a lithium-ion battery charger (any phone battery charger), these are available for about £2 on ebay.
In my phone the USB port had also stopped working for data transfer. I tried changing the board with the USB port on to no avail.
I replaced everything but the screen in the end to get it working.
Are/were you on stock OS or had you replaced it with another rom? Just for a bit more clarity of the problem.
