Hi guys,
I'm new to XDA Developers, so please let me know if I'm doing something wrong.
As I said in the description above, I am the unfortunate owner of a Huawei Ascend Y550, which after a reboot:
- takes 3 minutes to boot
- does not recognize the IMEI and baseband version
- constantly freezes / crashes
- plays no Sound
- wont longer recognize the Sim-Card
I have already tried a factory reset, which resets the device, but outputs the message "commom nv restore fail" (the problems are still there after reboot).
The Safe Mode did not solve the problem either.
With MatLog I have read out the logs, which are flooded by errors like these:
"Lib: oem_qmi_cmd: Connection failed !!, Connection refused, retry 456".
(Since the entire log is too big, please ask me to provide the full Log by Mail.)
Can someone help me in this case or give tips?
Or someone had a similar problem?
Let me know.
Try "Wipe data + factory reset" and then "Clear cache partition" in Recovery Mode.
I have already tried this several times, result: "common nv restore fail".

Hi guys, my sister has this phone and she has the following problem: the phone keeps crashing just after inserting the PIN (it says that the process.gapps or process.swiftkey has stopped working). We don't even have time to reach settings. I went in recovery mode (TWRP 2.8.0.0) and wiped data, system, etc, but after the reboot I noticed that the phone was in the exact same state it was before factory reset! Flashing a new ROM is not working either. I tried to change and downgrade recovery, but nothing. I also tried Original Firmware and Vol+, Vol-, Power, but it says
"update exception
emmc is readonly, you can't update your system"
Any suggestion? ADB does not find it in fastboot mode.

Hi there!
I have this Huawei Ascend 540-U01, from Portugal, running (or not running) its original rom. It was working find until it start to run slow. At boot it was blinking a half screen wite square, from time to time it shows "process com.android.play stoped" and some other times "com.android.google stoped". At this point I decided to enter in recovery mode and wipe cache and reset to factory defaults. The problem ware not fixed with this action and I decided to "scan system" from the recovery mode too. It showed lots of files corrupted. Knowing it woldn't solve nothing I tryed again for a reset. Now, the system simply don't boot, but I'm able to reach the recovery mode.
May anyone guide me (or point me) to re-install the stock rom for this device? It was not rooted and I can't boot on normal mode.
Thanks

- Fastboot says: "Warning: App has root actions first in 2015-01-01"
Good day, I dont know what happened to my phone. I'm just charging and this message popped out.
"Encryption was interrupted and can't be completed. As a result, the data on your phone is no longer accesible.
To resume using your phone you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up on your Google account." and a reset phone button.
I already did reset the phone, but the said message is still there,
i tried many things like flashing twrp through fastboot and then format data but it says cant mount storage,
flashed stock rom thru miFlash but same message appears, flashed custom rom but all apps are crashing and rebooting, flashed china rom still the message is there.
any suggestions? need help badly.
thankyou.
Sound alike the devices corrupted its self. Known to happen with Xiaomi devices. The hardware just ends up failing after a short amount of time.
Time to send it back for repair.
Hi, whenever I try to HARD RESET my phone, the following error appears:
EMUI
Software Install failed!
Get Help from emuiDOTcomSLASHemotiondownloadDOTphpQUESTIONMARKmodEQUALSrestore
REBOOT SYSTEM NOW
(Sorry I couldn't post link OR share the snapshot as forum is not letting me).
How to fix that?
Why I wanted to HARD RESET?
My phone's display suddenly goes BLANK (even though ringtone is continuing), this also happens anytime, even when unlocking. So I thought, wiping cache might help.
So, Anyone, please help. Shall be grateful.
Hi guys, please I need your help. I got a samsung A7 (2018) device which doesn't connect to network though SIMs worked even showing my contacts.
I made research and found out I have root the device since the IMEI has been tampered. I rooted with Magisk, i.e patched my AP with magisk right on my phone then flashed with odin. After rooting I downloaded Super Tool as per instructions cause I read alot of articles and watched alot of videos.
Now that's when I messed up, all I know is, I clicked "Restore original IMEI" while my device was in download mode. And upon reboot I was greeted with an error message telling me something like "update failed, connect to Smart Switch, then click on Emergency Software Recovery".
Tried that, didn't work. I reflashed using Odin several times, with even using PIT and NAND Erase but still nothing. It's just stucked at boot logo and whenever I reboot to stock recovery, this "E:failed to mount /.system" message along with other writings like "#no data on recovery_cause#" show up.
I tried many methods found here on XDA and other sites but still nothing worked. I even installed the PBRP Recovery I saw here on XDA, though that worked but it still didn't fix my problem. And it failed to install zip. 'Cause I tried installing my firmware, said "zip verification failed" and other zip files I don't even understand the message it gave.
I tried wiping cache and formatting, change file system and repair file system, still nothing.
Whenever I try the "Run graphics test" in stock recovery it shows "Installing system update" along with gage, then "Error", then "No command" then "Erasing" along with gage and then back to Recovery.
and whenever i try "wipe cache partition" option
Wipe cache partition->
--Wiping cache...
E:[PDP] lstat /c____/pdp_b__:0 - No PDP Scenario
Formatting cache...
cache wipe complete.
cache wipe complete.
I cut the story short for convenience, but I know you quite understand all procedures I took.
Please help me with anything you have, I would appreciate it.
I tried everything myself cause I want to know how everything works and because I want to study Computer Science. I'm faily familiar with codes.
I'm really sorry if you find my English hard to read or digest, I didn't mean to make it hard for you to understand me.
Thank y'all.
