[Completed] HUAWEI P9 lite (VNS-L21)-ROOT PROBLEMS - XDA Assist

Hi!
First of all, I'm sorry for my English...
I have unlocked and rooted my device (Huawei P9 lite).
I have install the TWRP bootloader and I tried to install a new costum ROM, but my device was turned off and never opened again. (Maybe: Low battery).
I try to charge my device but it didn't recognize the charger. So, I removed the battery from device (with the help of a technician) and charging it.
After all, I tried again to root and install TWRP but the device doesn't open or recognized of my PC...the only thing to do is to be recognized by the PC in fastboot mode but not allowing me to do something in the command window.
What am I doing?

[Q] How to unbrick Xiaomi Mi3

Hi guys.
I have for a few weeks one Xiaomi Mi3 16GB Snapdragon (WCDMA). Because I thought it was too slow, I flashed another rom by Mirecovery, but I think I used a wrong one because the phone is completely dead! I am not able to get access to the recovery mode or fastboot. The keys don’t work anymore.
This is the rom I flashed: xiaomi.eu_multi_NX403A_4.7.11_jb-4.2. downloaded on miuiandroid.com.[later I heard this is a rom for zte z5s mini, so really wrong one ]
After installing of MiPhone2.11.6, the first time when I connected the phone with the pc, the red led kept lighting on and the driver wasn't installed, but the phone was recognized by MiFlash(com20, i think): flashing did't work because there wasn't a communication with the port. After that I tried to reinstall MiPhone and afther some attempts, when I connected the phone with the pc, the red led kept lighting on for a few seconds and the driver was installed. But the phone wasn't anymore recognized by Miphone, so again no possibility to flash it.
I’m really desperate because i used the phone just for 2 weeks.
I would really appreciate if somebody would come with a good solution.
Thank you.

if you have no access to recovery or fastboot, the phone is finished
one of the worst things you can do to a device is flash the wrong software, as you see.

[Completed] [Q] Bootloop on Huawei Ascend G700-U10

Hi everyone,
First of all, I have some basic knowledge but treat me as an absolute noob please
I have a issue with my Huawei Ascend G700-U10. I tried flashing twrp recovery from the phone itself. It was either a wrong one or (I read that that could happen) something with the partition. The result is a boot loop. My PC does recognise the decive, but only for a few seconds. The flash tool does "try" flashing, but as the phone is disconnected too fast, I get an error message. Without much experience, I'd say that the only way I could flash something is making the phone stay connected longer or make the program flash faster. I have no idea how to make the phone stay connected and tried to only flash the stock recovery because I thought it would have to flash less and get it done in those two seconds that the phone stays connected. That didn't work though.
I thought about buying a new phone anyway, so if I can't solve it, it's not dramatic, but a working phone is always better than one that doesn't.
Thanks for your help in advance
Hi, thank you for issued XDA Assist. I think you're right that you need to flash the stock firmware. I'm not sure why usb would keep disconnecting but try different usb ports, the ones in the back of your pc, and cables.

Xiaomi MI4C don”t start !

Hi guys
I have a big problem with my Xiaomi MI4c , last night i flashed a incomatible room , not works and now my phone is dead. i Cannot boot , i can not use the download mode ,i cannot use the recovery mode, i cannot connect to pc:/
i need help, someone know how to fix it?
Thanks.
If the pc recognizes nothing at all and you can not enter fastboot, I don't know of any options.
However if you're bootlooping and can still enter fastboot, this seems by far the most successful unbrick method so far: http://en.miui.com/thread-237832-1-1.html

wrong boot img flashed. Now phone stuck in bootloop and won't be detected by PC

Hi guys,
Before i start, just be informed that i have tried google all possible solutions and tried them but to no avail. I know its a long shot but perhaps someone may be able to help however small the chances are.
My phone is a Xiaomi Redmi Note 3 Snapdragon variant and is rooted.
What happened was, i tried installing TWRP (kenzo version) on my phone and so following the "instructions" in the downloaded file.
I used Flashify to flash the boot.img and then redmi_note_3_Twrp.img then the phone prompted me to reboot.
Now my phone is stuck in bootloop. The only thing i can do is to boot into Fastboot. So i tried accessing fastboot via ADB hoping to be able to some how flash the original boot.img back.
The problem i have now is that i am unable to access the phone at all even though i can go into fastboot. It wont be detected by my PC. I tried Minimal ADB and Fastboot and PdaNet.
Is there any other way for me to detect my phone and run some form of command to get it started again? Any help at all is appreciated. The phone is fairly new and i'm regretting trying to get the latest ROM for it.
I'm hoping i'll have some luck in a helpful community such as this.
Thanks guys.
Omg!! someone with the same problem as me. The same happened to me. Flashed a CWM file now am stuck in a Bootloop and ADB wont find my device either

Head over to the MIUI forum and search unbrick under the Redmi Note 3 forums. I can't post the link here unfortunately
You can also thank me after you unbrick your phone.
This only applies if you are uaing the Redmi Note 3 Pro

Well if that's the case i suggest googling how to get into EDM mode for ur phone and using your phone brand's flash tool to flash a new ROM onto your phone. This means you will not be able to save your phone's memory. Is your phone's bootloader unlocked?

yes it is unlocked,
i think? When i entered fastboot mode. One of my apps says bootloader enabled and when i typed 'fastboot devices' in the Minimal ADB and Fastboot its shows:
0123456789ABCDEF devices
whereas if I type 'adb devices' i just shows:
List of devices attached
The main problem is the driver, i cant get adb to find my device. I have tried the universal usb drivers like Kouch but no success. My device is listed in the Unspecified section in my computer

Question Rog Phone 5 Brick

Hello to all,
I apologize in advance for this message.
I mistakenly bricked my phone,
It was running WW-18.0840.2201.226 (Android 11).
I'm not sure if I'm going to be able to use it again, but I'm sure I'll be able to use it again in the future.
The recovery mode does not work anymore. It remains stuck on the logo.
Concerning the device manager :
In Bootloader, nothing is detected
When I test the recovery mode, it detects 'Android Composite ADB interface'.
However, the ADB commands do not work (Unauthaurized)
This is a call for help, I don't know which tutorial to look at to help me.
Do I need to get a Deep Flash Cable to restore the phone?
Excuse my English, I'm French ^^'
Hi, I'm not sure, but I think you will have to delete this POST... It doesn't respect the forum rules... That said, you can follow this link for your problem. https://forum.xda-developers.com/t/...to-unlock-bootloader-to-modify-country-cn-to- ww.4353865/não lido
Hi Rico,
If I have to delete the post I will do it, it's not a problem.
Do you think I can put this post in the topic you gave me?
I had come across it in my research but I didn't know if it needed a Deep Flash Cable
I didn't know that my problem was similar to the one in the post because I don't have a 9008 mode

There is nothing wrong with your post at all.
Do you have access to see and send Fastboot commands to the phone when on the bootloader screen? You need to get that right first and get your driver on your PC sorted. Forget ADB, that's not going to help you here.
Once you have sorted the above, doing a RAW flash following one of the guides you can find on this form with a rom version that matches your device should get you back on track.
At this stage you shouldn't need EDL or a deep flash cable before exploring the above option.
Good luck.
Hello Andrologic,
Thanks for your reply
I only have access to the Bootloader with 'Start / Restart Bootloader / Recovery Mode / Power Off'.
I bought a Deep Cable, this one detects me when I connect it to the pc, previously my other cables did not want it
So I can indeed use the Fastboot commands whereas before I couldn't

Thank you very much Andrologic!
The phone works like magic again, I can't believe it T_T
When I should do the updates, should I reflash the phone?
It doesn't offer me any new ones even though I'm on Android 11

Nice. No, I would suggest updating the conventional way, i.e download ROM for ASUS and let the device pick it up and flash it. If you have TWRP installed, you can flash from there too, but there is no need for that unless the first method is not working
