Need help with zte grand x z777 cricket version. - General Questions and Answers

I let a friend try to root it and he screwed me. The phone won't boot into the os, fastboot, or recovery. in fact it constantly tries to install some new recovery but gets to 25% and repeats. I can get into download mode, I assume it's download mode. that's the only way my pc will recognize the phone. I've tried everything, can't even find the stock rom and recovery for this thing. ADB doesn't see the device nor does fastboot. Am I out of luck or is there some type of fix for this?

[Q] Help, my device won't boot!

So basically I rooted my LG p500h and installed a ROM through ROM manager, the thing is that when I rebooted the device I got stuck at the analog to the Android logo that shows up after the LG logo. I flashed an stock ROM through KDZ update software but after the program did it's thing, I did hard reset the phone and got the same problem: won't boot up and forever stuck at the android logo. I can get to emergency mode tho and when usb connected will show the battery charging up. I have searched solutions and I haven't reached one yet so everyone told me to post here and ask for some help! I hope it's not the end of my device Any help is sincerly appreciated!

Much as I hate to say it, ROM Manager is not friendly to our devices. Secondly, stay away from KDZ too. But don't panic. You do have options. You will need to use either ADB and dd commands, or fastboot and fastboot mode. Since you can't boot, most likely the ADB way won't work ATM. Both methods require either the ADB binaries or the Android SDK. An alternate method would be Android Flash Recovery. There is a link in my signature. There are complete instructions in the download. On thing, put the device in fastboot mode before connecting it to the PC.
Enter into emergency mode, BACK+VOL UP+POWER
then follow this guide to flash recovery: http://forum.xda-developers.com/showpost.php?p=15217609&postcount=3
After that enter into recovery, HOME+VOL DOWN+POWER
then wipe data/factory reset, wipe dalvik cache, wipe cache, format system then flash a rom of your choice like oxygen, cm9 present in development section.
Then reboot

Odd enough, I plugged in the device to the computer after the USB drivers got installed (following all the instructions given by the files provided), I went to the bathroom and left the cell phone unattended, just to find it boot up! weird. Anyways your advice was very helpful and very clear! Now I will figure out how to get my old ROM for my country. Thanks again!

[Completed] [GT-N7000] Stuck in manufacturer Logo, unable to enter recovery can enter download.

Is my device soft bricked?
I flashed PhilZ-cwm6-XXLTA-ATL-5.15.0.tar which worked, then I started up the phone and tried to flash CWM 6.0.4.3 touch using ROMManager, the process was a "success" but after the reboot attempt the phone was unable to boot OS nor is it able to go to Recovery mod. I am still able to enter download mod.
I tried flashing PhilZ-cwm6-XXLTA-ATL-5.15.0.tar again, but it didn't work. I can detect my phone in ADB devices and in Odin3. I am currently searching for a stock ROM for my device.
If anyone has experienced this before and knows the result already, could you tell me whether my device is lost or I can revive it somehow? Thanks in advance.
EDIT: My phone doesn't seem to go into recovery, stuck at manufacturer Logo(Not restarting); but in ADB devices I can see it in recovery mod and can see its contents in adb devices.
Solved: It booted normally after deleting update.img and cache via ADB.
Thread completed as user already founded the solution.

Cant enter download mode

Hello, I have a Blu life one (x010q model) and I tried installing a twrp recovery for it, and it bricked. Now I can't bot up the phone or even get into revovery mode, it's just the menu screen boot loop never going away. I tried to use a software called oneclick unbrick, but I can't even use it without getting into download mode. Any ideas., or is there a better way to fix it?

Helping Hand please !

Im stuck on nvidia logo. With no recovery and OS.
I am planning to go back to stock.
But i cannot connect shield to my laptop. It doesn't connect, it just charging. I tried adb, i tried my device manager but i still got nothing.
Please, if anyone knows a solution on how to connect. Or to go back to stock
How do you know there's no recovery? Did you mess up the partition?
That part, i mean i used fastboot and success, but im stuck. Like its not installed. But when i tried twrp 3.1 it was installed but the problem is it wont touch.
If you can access fastboot, that means you can pretty much re-flash recovery and the ROM. Download the latest recovery image file from the Nvidia download center (it's 5.1). Don't need twrp for that

Major help on Samsung S7

Hello,
Who can help me on a major issue.
I tried to recover some photos from my phone and I installed dr.fone application on my pc. At one time, the application stucked and the phone also and I can't boot it.
I tried to put the phone in safe mode, and no luck.
It stays at Samsung logo and the led is blinking blue.
I can only put it in the stage where I can install a new firmware on it.
Can some tell me how can I boot it, without reinstalling the firmware ? Also the temperature of the phone is high.
Thanks
Do you have a custom ROM on the phone or stock?
Are you able to get the phone into recovery? Or only Download mode?
If only Download mode, try using Odin to flash TWRP, then boot into Recovery from there. Once in TWRP you should be able to use File Manager to access your pics if they're still there.
