I have accessed a hidden menu with *#*#4636#*#*, and from various options I selected "CDMA prl auto" (original setting was "GSM only"). My phone is one of those China phones that works only on GSM network.
Now, my phone is stuck in some sort of boot loop (only part of loading logo shows and by part I mean only logo and no animation).
I can't access CWM nor download mode and I tried almost everything mentioned over here.
- I tried with adb, phone is not found.
- I tried with ChannelServer and ResearchDownload (phone is sometimes recognized by my PC as "Unrecognized USB Device" and I had some hope).
- Holding Volume +/- and Power Up doesn't go into download mode or CWM, it just shows the logo.
Phone specs:
MocorDroid2.3.5
MT6515_C910_HT_M2_EN_V03
6820_2.3.5_C910_HUITENG_M2_EN_V03
sprdroid_base-user 4.0.4 MocorDroid2.3.5 MT6515_C910_HT_M2_EN_V03 test-keys
I do have a backup made with (I think it was) CWM.
Phone is rooted, if that helps anything.
Any help would be greatly appreciated, because this is my only phone.

Hello,
I think I bricked my BQ Aquaris 4.5 phone but I'd like a confirmation:
I did a "wipe data/factory reset", and now my phone boots into a picture of an android robot being updated right after the operator logo. The image is animated, but it seems to be in some sort of "reboot" loop because it flashes black periodically (it doesn't completely reboot the phone tho, because I only see the operator logo the first time the phone boots).
Here are screenshots of what I'm talking about (since I can't link urls because of my new account I'm forced into tricks):
- tinyurl id o9d4h9z
- tinyurl id nenpfz8
When I plug the phone on my laptop, I see /dev/ttyACM0 for a short time but adb fails to connect to the phone (it's basically only available when the operator logo shows when the phone boots). I can't boot in recovery/fastboot/whatever anymore by pressing volume down after I reboot it with power+volume up/down.
I have an external SD card on that phone, is there any hope for me to boot onto it if I format it right? Are there other key combinations/tricks to put the phone on fastboot/recovery? I tried some trick around adb but adb just can't connect to the phone anymore.
Thanks in advance
soft bricked.
I think I may have bricked a phone it says unfortunately the process com.android.phone has stopped
Acer 7
A neighbor girl I know round here dropped her broke phone off at my house while I was out, when I got it the plastic rim was off and it was flashing on the home and lockscreen with low battery, when I enter recovery or factory mode it boots up and then displays a blank black screen, so I'm suspecting if I firmware flash a new factory image it might bring it back out of this state hopefully, but the drivers page says unavailable and I've yet to to find motoflash tools and any factory firmware images, I'm in the menu
Start
Restart Bootloader
Recovery Mode (When I enter it it says not connected)
Power Off
Factory Mode (Again it boots up to a blank black screen after optimizing 36 apps)
Barcodes
BP Tools
QCOM
Bootloader Logs
Where do I need to go and where can I find IT? Thanks
Fixed it with this
Yesterday I loaded new rom for my phone through cwm. Everything was ok until when in the phone the screen flashed (joining in and disconnecting the phone. It isn't turning out even a logo lark'a neither of android. I tried to enter recovery mode but into it I didn't also manage to access myself. Only into the boot mode which I have 3 options to choose from in:
1. Recovery mode
2. Fastboot mode
3. Normal mode
But when a phone wants to choose some of options is ignoring (simply when I am clicking on vol- nothing is happening)
Rom I have from mtk roms 12.1 cm
I have copies earlier rom'u but I don't know how to put it in. When connection through usb the computer isn't detecting the phone
**The problem as it stands**
My Galaxy S6 Active is stuck in a sort of bootloop, except it never seems to attempt a boot. If it was turning on, without any combination of keys, it would go to the "No Command" screen. From there all I can do is force reset (power + volume down) to get it to restart to the same place or as it displays the Samsung splash screen, press volume up + power + home, it goes to the download screen. From the download screen, I can use my pc to flash a rom (that may not be correct) to the device and according to Odin, that is a success but my device freezes on "erasing".

**Description of the problem when it was booting**
At seemingly random times, the device would freeze and the only way to get it to do anything was to reset it. Sometimes it would enter a bootloop but through key combinations, I would be able to get it out. One time after a bootloop, I had the sense to back up the device's storage, so luckily I have that.
**What I've done**
- I have tried wiping the storage in device recovery -- when it was accessible, I can no longer get to it.
- I have tried using Kies/Smart Switch emergency software recovery -- but when provided with the model name and serial number they would both crash.
- When the device booted, I tried using the standard recovery feature in Smart Switch. I can't remember the exact message but it was something along the lines of "This device does not support initializing"
- I have tried using Odin to flash ROMs (again, I may be using this incorrectly) to the device. I have only tried Samsung release ROMs, meaning ones that have not been modified by a 3rd party. I followed the second and third methods of a guide on XDA forums (https://forum.xda-developers.com/ga...e/downloading-flashing-att-galaxy-s6-t3260744). Odin never throws an error and it always says it was successful. During the device's initialization with this new ROM, it gets to 32% then goes to "Erasing". A few seconds later the animation freezes. I can leave the device here for hours but nothing happens. So I believe more than the animation is frozen.
- I tried using ADB recovery via the device's recovery mode (when it was accessible) but from what I can gather, Samsung uses a proprietary ADB interface that would not work with what I was trying to do (I was following method 3 of the previously mentioned guide (https://forum.xda-developers.com/ga...e/downloading-flashing-att-galaxy-s6-t3260744). I would always get a message saying "ADB server out of date".
I may have done more than that but that's what I can recall.
Any help would be appreciated. Even if you know of a better place to post this, let me know.
Thanks
My s6 active did the same thing on 08/24/17. I have not yet found a solution.
Hi everyone, I just received my Teclast M30 (10-inch tablet), version M5P3. I tried flashing a custom ROM but - surprise - I'm stuck on a bootloop.
The stock ROM was an Android 8 version. It is not rooted.
- I went into the developer options and allowed Bootloader unlocking via the corresponding option.
- Then via fastboot, I unlocked the Bootloader via (without any error):
Code:
fastboot flashing unlock
- Flashed TWRP, found on the only Teclast M30 thread... (=> https://forum.xda-developers.com/showpost.php?p=81064235&postcount=56) via fastboot (without any error):
Code:
fastboot flash recovery twrp-3.3.1-teclast-m30-20191201.img
- Flashed a GSI (ARM64 A-only) ROM (without any error). I used the "Android 9 - Havoc-OS v2.9" ROM on this link => https://github.com/phhusson/treble_experimentations/wiki/Teclast-m30-(MT6797x-helio-x27))
Code:
fastboot flash system Havoc-OS-v2.9-20190914-phhgsi_arm64_a-Official.img
I realized after a few hours that the TWRP I used was for the M4P7 version and mine is M5P3.. so I now know what I did wrong but even with this info, it doesn't help for my problem.
When trying to boot after flashing, I'm stuck on a bootloop.
It shows the Teclast Logo with some text saying it's in Orange State (= show a message saying the is bootloader unlocked) and then go to a screen with an Android Logo and a message saying: "No Command".
This "No command" screen is well known in our forum BUT problem is this screen stays only for about 3 seconds, and then the screen become black for 1 sec, then the "No Command" screen appears again for 3 sec, then it disappears again, endlessly. Here is a video of what's going on https://www.youtube.com/watch?v=O1iiu6MtOyM
Pressing "Power & Vol+" or "Power Button & Vol-" on this screen does nothing, I just can't enter fastboot mode as it keep looping and do not stay on the "No Command" screen.
When the tablet is completely shut down, I tried powering it up pressing just the "Power" button, but also "Power & Vol+", "Power Button & Vol-" but it does the same thing every time. It also acts identical whether the tablet is plugged in to the computer or just charging on the wall plug.
There is a "Reset" button on the tablet (must use a SIM pin to press it) but it seems useless to reset the device. When pressing it, it only shut down the tablet and stops the loop. I tried pressing it for long periods like 10-20-30 seconds in different situations but it just shut down the device and do nothing.
Does anyone have any leads on what I can do to revert back to original state or even just access fastboot mode ?
Thanks
I have the factory firmware file for my tablet (the good version this time..) now, but still the same problem of looping...
For future reference:
I fixed it thanks to the stock firmware and a tool (SP Flash Tool) that are both included in a file package provided by the constructor (at the time I created this post, this file didn't exist on their website. Now it does ).
This file is hosted on Baidu (only accessible with an account, and you need a Chinese phone number to create one) so I uploaded it on Mega if anyone need it:
