[Q] Help for my Huawei Ideos U8150

Hi all,
I was trying to install a new Rom Dronix 0.4. Upon entering the bootloader I accidentaly somehow no idea how,deleted clockwork mod recovery that was on there and now just can't get into bootloader mode or even get my phone to start up past the 1st screen.I've tried volume up +green button and power button to try to get in,volume down + end call red button and power button no go.The only thing it goes into is if I hold the volume down button + call green button and power which takes me to the firmware update but just flashes and says unpack failed.The other thing is that if press the red and green buttons for calls and the power button it brings the screen to a purplish colour but does nothing as well.I've tried to get the computer to recognize the phone but it won't even after installing the usb drivers with windows xp and windows 7.Atm there is no ROM on the phone after deleting it,cache and dalvik cache. It's just empty with not even a bootloader to try and boot into, only hardware is available now.
I'm at a loss as to what and any help if trying to get it back and running would be appreciated.
Thanks,
Paul

Problem after installing 4 button/overclock

I have a big problem with my Lg optimus 3d with Darkroom ICS.
After that i tried to install overclock with 4 keys fix from this thread http://forum.xda-developers.com/showthread.php?t=1982744
my phone wont boot up. Here is a link to show you the problem: http://www.youtube.com/watch?v=BfdHevSyR0c&feature=youtu.be
the last thing I do in the video is holding power+vol up+3D and then I get a error screen in Korean.
When i try to connect it to my computer it just wont stay connected. (The connect and disconnect sound beeps with around 3s between)
Do anyone have a suggestion on how to fix this?
Sincerely, Henrik

Try this:
-keep battery in
-hold vol+
-connect usb (hold vol+ 'till you enter download mode)
-flash ICS via LG FlashTool
oh and make sure you've installed the whole drivers.. (for omap4430 etc)

Thanks! :good:
I have successfully been able to enter download mode. I have also installed omap drivers and LG drvers. But
LG flashtool dosent start the flashing process. Any sugestions on how to solve this?
I have been looking around on other guides and the all say you need to connect your phone without the battery, but I cant do that as my phone wont stay connected.
Sincerley, Henrik

I just did mine. Leave the battery in. Connect your phone and it will power up for 3 secs then power off repeatedly. While this is happening, hold Vol + and Power and you'll enter download mode with the korean screen. Flash ICS404 again with LG Flash tool or smart flash (I used smartflash cos it was simpler and quicker)

Please read all before flash
Anyway was not necessary to reflash all the rom, you can just fix through wkpark fastboot

Please tell me i didnt kill my phone!!!

Ok so my fiancé pointed out that her phone got an update and I liked how it looked so I wanted to update mine. but I couldn't because of root. and so since I never use my root I went into super su and hit the unroot button and then my phone reset I have been in bootloop ever since. before someone suggests NO I cannot use ODIN because it wont register my phone being plugged in. YES I have the proper driver installed I triple checked and no my computer does not register the phone either. is there anything that I can do?

You didnt kill your phone!!!
The reason of bootloop is that when you press unroot in superSU it also restores unpatched stock boot.img which doesn't boot with custom recovery.
Hold power + home + volume up + volume down for 7 seconds to hard reboot your phone and enter download mode confirmation page. Press volume down to exit downloading mode and immediately hold volume up + power + home until you enter recovery. Do a factory reset.
Enter download mode confirmation page again by same method and press volume up, connect phone to your PC. Now if Odin doesn't recognize your phone then that 100% Driver or USB Cable problem. Flash latest official firmware and you should be good to go.

Nice tut! Anyway, if he still can't get recognized by PC, i suggest to try different PC, i had the same problem a while ago, my pc wouldn't recognize my phone in odin no matter what. Then i checked on my friends PC and it worked like a charm. It must be USB ports problems.

if your pc does see your phone but the odin still fails you can just use smartswitch and do emergency recovery tyoe your model number and imei in and sit back and relax and you are done

Thank YOU!!!!!!

Nonsense.... I used it when I trashed my EFS / Modem
Smart Switch does work, check your USB drivers and internet connection.
At the end of the process smart switch does verify a lot of thing, when your CPU from your computer is slow it will hang a long time on 94%

, can't enter into recovery mode, c'ant enter in download mode, even my pc and odin doesn't recognize the device at all, please help I can't afford a new one.
Thanks in advance.

Just flash stock rom with odin, conect to pc pressing vol + and vol - to get download mode

It doesn't react with + - buttons, that is why i can't flash it

What is the last OS you are running?
If the phone keeps restarting, first connect the phone to your PC via USB cable.
Then
1. Keep Vol+ and POWER pressed.
or
2. Keep Vol- and POWER Pressed.

Thank you but it seems that my motherboard is damaged

I do not think it has been damaged, try pressing vol + vol- boot at the same time a couple of times and then the third release the vol + i the boot and it will restart in dowload mode. then flash with odin each of the partitions of an original rom.
good luck

Stuck at entering fastboot mode

How can I get my Galaxy Note 20 Ultra out of stuck at 'entering fastboot mode'?

Hold down power and volume down until it reboots back to recovery. I got stuck there last week and that's what worked for me.

Is this problem solved? I cannot boot into bootloader mode, thanks!

Switch off the device. Then hold volume up and down buttons and insert the USB cable plugged to PC. You will get to download/odin mode

Download mode is different from fatboot mode, I can enter, and works ok download mode. However, fastboot does not, it gets stuck in entering fastboot mode and no fastboot command works

I got same issue here, I've tried rooting via TWRP and after data wipe and "reboot to recovery" it got stuck in same thing and doesn't move at all, if I hold power and vol down it just boots the device which i dont want since i need to flash magisk as a last step. if anyone encountered this or knows how to fix it i'd be helpful

I'm not rooted but I've had past Samsung devices that I was able to root and if I'm not mistaken Samsung phones aren't able to boot into fastboot mode because Samsung removed the ability to. You can run commands via ADB mode but I think that's about it

i cant eneter into download mode by using volume up and volume down ... the only thing that happens is the battery display kicks in .. is there a trick on how long to hold the volume bottons .. or any special way of doing it .. or for the usb c while trying to connect it to the computer
it gets stuck into fastboot entering if i try to do it the old fashion way .. please help

Guys, turn off the phone, press volume up and volume down together, and plug the usb cable while pressing volume up and down, and wait until the phone enter in downloading mode. This work for me.

Thanks Man. This worked.

Since we can"t enter into fastboot mode is it possible to flash boot.img with adb commands?

I m having the same problem with a21s(a217f). I can t enter download mode using key combinations and the other way launching it from recovery doesn t work, it stays stuck at,, entering fastboot mode,,
The ROM is already bricked, it says in recovery when i try to factory reset the following error:,, can t mount. /system (structure needs cleaning)
Even with,, apply up. with adb,, doesn t work, it just doesn t get detected on my computer when i checked with adb tools.
! The only thing that works is that I can access my sd card and apply a update from sd card but I don t know where to get the update file. (I ll edit if it works to flash stock rom from,, apply update from sd card,, )
Anybody got some ideas or should i burn my motherboard and replace it?
sorry for bad english

Honestly plug device into PC.
Power off device
hold all 3 side buttons. Volume up and down and power/bixby.
Should usually work.
After in fast boot you must press a button Volume button to find via odin.

I already did that, unplugged the battery, reconnected it after 1min, connected my phone to the computer and pressed all 3 side buttons, still doesn t work. I guess the download mode is deleted or something..

Volume up & down, no side key, then connect to PC. Works for me. Connect to PC first does not work for me.

It wouldn't be deleted as it's a safety protocol if the device has a bad update and freaks out.
Maybe try to person above method.
Normally I can enter download mode with any of these methods if you cannot I'd suggest trying to get the device replaced due to software malfunction

Samsung phones use a tool called Odin to flash firmware. If you're flashing custom firmware firmware you'll need to have your bootloader unlocked.

I got mine into download mode just now. It's a Galaxy A13 .. Like stated above, try to hold all three buttons down and connect to USB. I had to let go before it showed the battery charge icon. From off. If not from off try from charging. I think that's what I did just now. Plug the usb -> let it show the charging icon (from powered off!) -> hold all three buttons, let it power on, let go. DONE.

just follow this video it helped me a lot to unlock my boot loader
