[Q] Huawei Ascend P6 stuck on android logo - Android Q&A, Help & Troubleshooting

Hi,
I have a huawei ascend p6. It was for a whole day out of battery, when I connected it back to the charger it wouldn't boot. I'm getting the Huawei ascend screen and then an android logo which I've never seen before and from there nothing.
I can go into recovery system and I did a factory reset (not sure if that was right). I tried uploading the official firmware from an sd card but it tells me "E:failed to mount /cache (invalid argument)"
Any help would be much appreciated.
Thanks

I gave it to a mobile shop, they kept it for 2 weeks and then they told me they can't find the right software. I don't think they have any clue either.
If someone has an idea I would be super thankful! I love this phone and I'm not ready to give up yet hehe

Hi! What firware do you running? Did You put to /external_sd/dload/UPDATE.APP ?

Stuck at formatting /cache

Hi there,
I have had a problem when trying to update the ROM of my Ascend g300.
While doing the factory reset it got stuck on formatting /cache. It appened a few hours ago and it's still there. I already pulled out the battery but as soon as i turn it on, it goes to the same screen. I cant do anything else on the phone, not even go to the recovery screen.
Anyone had the same problem/ knows how to fix it?
Best Regards.
Anyone?

[HELP] Huawei Asend Y200 / U8655-1 SIM not deteted

Hi there! I recently rooted my phone with CWM 5.5, all was going well until I decided to flash a new OS onto my phone ( ). But now it won't detect my SIM card or connect to wifi! When I bring down the status/settings bar from the top of the screen, it just says "Emergency Calls Only". I have searched high and low on how to fix this, but I am having no luck. I have downloaded firmware directly off the huawei site and attempted to update by putting an update.app onto my SD card, but it gets halfway through and says "Update failed.". I have booted into CWM and have tried to flash the stock kernel, but this dosen't work. Stupidly, I don't think I backed up my phone properly, as I went to backup in CWM, then tried to restore the backup later, but that didn't work either. Any help would be much appreciated, as this is my first android phone that I got a couple of days ago and I really don't want to have to buy a new one. Thanks in advance

[Q] MDM Removal Help - Galaxy S5 Sport (Sprint SM-G860P) Stock Flash Problems

New to this forum but skilled in most things IT. I need help removing MDM restrictions and/or flashing a Samsung Galaxy S5 Sport (SM-G860P) to factory defaults. Here is the problem...
I purchased a Samsung Galaxy S5 Sport (Sprint SM-G860P) from Craigslist. When I received it, I instantly saw that it was a demo model with MDM restrictions that would not allow Factory Reset from within settings when the phone was booted normally OR when the phone was booted in Recovery Mode.
I used Odin to flash the stock ROM but this did not delete the demo software or remove the MDM settings. Stupidly, I tried using the Nand Erase All command in Odin and now I receive the following error when booting to Recovery Mode:
E: failed to mount /data (Invalid argument)
can't mount '/data' (Invalid argument)
E: failed to mount /data (Invalid argument)
E: Can't mount /data/log/recovery_log.txt
E: failed to mount /data (Invalid argument)
E: Can't mount /data/log/emmc_checksum_log.txt
When I boot the phone normally it hangs on the yellow "Sprint Spark" screen until the battery dies. I've tried many different .tar files and methods of flashing with Odin but to no avail. Attempting to reset the phone in Recovery Mode still gives this error:
MDM does not allow factory reset
I don't know if there is a way to remove the MDM settings and restore the phone to factory settings. I'm not sure if I need a PIT file to re-partition the phone, but I can't seem to find one online.
The phone is running KitKat 4.4.2 with G860PVPU1ANG2 originally, but I found and installed G860PVPU1ANG3 so when I am in Recovery Mode it reads at the top of the screen:
KOT49H.G860PVPU1ANG3
If anyone can assist, I'd be much appreciative. I've downloaded and installed Android Studio but have never really used it before and I don't know if there is any software that will allow me to remove the MDM restrictions and flash the phone to factory/stock.
Please let me know if you need any other information from me. Thank you in advance.

Anyone?
Is there anybody out there...?
Remove records of rooting attempts?
I stopped into Best Buy and spoke with a kid in the new Samsung department they have. Nice kid, but not very educated on flashing phones or rooting or installing ROMs. He explained that he had a tool that would allow him to wipe everything out and install the newest stock firmware. However, after a couple of attempts and having to manually enter the model info, he received a message that the phone is rooted and he is not able to fix the phone. I know that the software he was using is some special Samsung software that doesn't allow the user to work on phones that have had their warranty voided, but I would think that someone would be able to bypass that restriction and wipe the phone anyway. But this kid wasn't able to...SOOO:
In the state that the phone is in now, is there any way to remove the info that shows rooting took place? I'm hoping that if their special Samsung software doesn't detect that the phone warranty is voided from rooting attempts then it will be able to restore the phone.
Please, SOMEone, help me out! Thanks...

ZTE Nubia Z11 Max NX523J Stuck in BootLoop after V1.43 Update Failure

Hi Folks,
The Phone is stuck at Nubia Logo, and just stays there. TWRP was successfully installed and phone was rooted. Before actually loading the update package, i performed a wipe (delvik, system, data) and flashed a Stock Recovery. It prompted for Reboot which i did and the bad luck started.
Now, Vol-Up+Power boots into stock Recovery but unfortunately i do not have a backup nor an official Nubia ROM for the handset & hence can't do anything. Vol-Down+Power boots into Bootloader in which all the options pretty much take me back to Stock Recovery.
I know i made a stupid mistake but it would be really really helpful if anyone could please help put an end to my misery and undo this error. I have already tried discharging completely and then trying to power it back on again but to no avail.
Thanks in advance
Guys, a little help here please!!
My laptop does not recognize the device, it doesn't even appear when connected via USB Cable, although it charges alright.
I tried installing Nubia Recovery Tool but unfortunately it was in Chinese and I could not understand one word of it.
Please HELP!!
Hi Goraya,
I get a lot of answers from Pesa1234, hi is from Italy so his English is not that good.
I use the ComboRom 4.2 and in principle it is good, although I don't have fast charging.
