[help] Huawei Ascend G740 in reboot loop - Huawei Ascend G7 Questions & Answers

Hello, my g740 was working normally, yesterday I did put a sim card in it and it went in reboot loop even once removed.
I don't mind doing a factory reset except I saw sometime it removes data from internal sd card too, any way I can recover files from it before ? Maybe recuva would work though.
I don't have a micro sd card nor a usb adapter to connect a usb key (not sure it would help anyway), all I have is my PC to connect it in usb.
Please help me I'm sure you can help even if you don't know that phone (it's on android 4 and system recovery is 3e) thanks :crying:

[Q] Unable to Boot without SD

Hello,
Any and all help would be appreciated.
I am able to boot off the SD just fine. I can't boot without the SD. Nothing happens. If I have it connected to the PC I hear the PC recognizing a USB device but nothing on the screen of the nook.
I can't get into RECOVERY at all.
Here is what caused this. Really dumb... I tried to restore a RECOVERY backup from another Android device. At that point I was booting off the internal flash.
What can I do? Thanks in advance.
UPDATE:
I was able to get into CWR from SD using info finally found in this thread...

SD Card

Just unlocked bootloader and installed TWRP and root etc. on MXP all working.
SD card is now not seen by phone and not when connected to pc by cable. Card works in pc and moto g 2014.
Sandisk Extreme 32GB
I've searched but cannot find anything.
Thanks in advance.

Still no fix. Factory data reset. Reformatted SD card to exFAT. Still not seen.????
Can't see this as a hardware problem. Please, anyone...
11/7
Phone sent to repairer in Manchester (UK) who said they could fix it; had it for nearly a month. Finally said it was not repairable. Sent it back boot looping and flat battery. I managed with fastboot to restore stock ROM then rooted again. So now it is as before, working correctly but no SD card recognition. The pins in the reader look unbent.
Do I give up on this?? Is there a software fix or command I can try? Mainboard damage?
It all seemed to happen when I unlocked rooted etc.
Estoy igual , ayudaaa

System files transferred to Sd Card now phone won't turn on or connect to PC via USB

I rooted my Samsung Galaxy J5. Tried to swap my internal storage to my Sd Card. I transferred all of my files (including my system files) to the Sd Card and then restarted the phone.
Now the phone will not boot up (not turn on at all) and the phone will not connect to the pc via USB.
How can I fix this problem? I am running the 5.1.1 OS
The phone will not boot while holding the power button for 20-30 sec., it will not boot either mode while holding the (vol+/pwr/home) or (vol-/pwr/home).
The phone will not sync to the computer while in the Device Manager mode on my PC so I am not able to restore the galaxy from a recovery .exe
Thanks in advance.

Z17 Lite won't boot after v1.05 ROM update

Hello,
After rooting the system I tried to upgrade the stock firmware.
I probably did something wrong because now the device won't boot.
At startup it shows the "Nubia... Powered by android" screen and does not continue with the boot process.
I still have access to TWRP so I tried to wipe everything and to install the ROM from TWRP.
It looks as if the ROM is installed correctly, but it requires reboot and after reboot the same "Nubia... Powered by android" screen comes up.
I also tried the emergency recovery but that installs only from external sd card (that the Z17 lite does not have), or from OTG device. I connected a USB thumb drive with OTG cable but it doesn't recognize it
At this point I have no idea what else to do.
I'd be happy for any assistance.
TIA

UPDATE: I tried different USB drives. One of them mounted. I found that this one was formatted in FAT. Since this is a small 2Gb drive that cannot hold the ROM, I found another drive that was formatted in ExFAT that also loaded correctly.
I loaded the ROM as suggested and now the phone is working again.
My guess is that the phone can't read NTFS file format in emergency recovery mode.
