[Completed] pantech vega a860L boot loop - XDA Assist

my vega has boot loop. i cannot boot into recovery because it stucks there whenever i try to get into recovery. the only thing i have is fastboot. adb is useless because no usb debug. i connect it with my computer its detected as fastboot but i cant do anything to format it. i try unlock bootloader and it worked. but after i use run_cwm_adb.bat to boot a temporary recovery it has locked back my oem bootloader. after i runs the file.bat i managed to get into recovery,but it said failed to read system. i try to mount everything it still failed. so how should i do? wish i could make a bootable sdcard to fix this. it thinks its iso faulty. please help me. this is my email [email protected]

Hello, and welcome to XDA! Perhaps you could try to fastboot flash the recovery again. If that doesn't work, reflash stock firmware. Or if you register, you can post your question here for more help: http://forum.xda-developers.com/android/help
Good luck!

Have you tried reflashing recovery via fastboot? If you see the Google logo it's trying to boot.
Reflash recovery via fastboot and reflash your rom of choice.

I'd tried and didn't work either, but i was able to get to the bootloader screen. I can't get my computer to see the phone while its in the bootloader screen.
Maybe you could boot into recovery from the bootloader and use a nandroid backup of some sort?

I can't get into recovery from bootloader, when I click on recovery, it looks like it's going to boot but nothing happen. I leave the phone on over night and nothing happen.
Ah...no worries..
stay in ur bootloader.
download a clockworkmod recovery image and cd into the directory u r in.
Perform the following commands if you ALREADY have a recovery img installed:
1. fastboot erase recovery
2. fastboot flash recovery _____.img (the blank line is the recovery img name)
3. reboot into recovery and perform ur nandroid
If you DON'T have a recovery img installed, then skip step 1

Soft Brick..no USB to help
Nexus S 4g is not connecting to the mobile network. Because of this I am trying to go back to the Sprint stock firmware. USB is properly charging my phone, but I'm unable to have the device enumerated by my pc. I've tried multiple cables, OS's, and PCs. USB is not enumerated even in the bootload state.
I have reverted to a backup when everything was working, but I still have the same problem with the network and USB.
WiFi works so getting new firmwares from ClockworkMod is an option, but going to CM7 did not resolve the problem.
I've read the forums and not found any solution yet. Has anyone heard of this before? Are there any options I can still try through software?

[Q] Can't fastboot / No recovery JB

I have an interesting problem:
I have a tf300t curently running JRO03C.ww_epad-10.4.2.17-20121018
I ended up here after an unsuccessful flash with twrp. Tried to recover my back up with no joy. At this time it would only boot twrp recovery, finally flashed stock via micro sdcard and got it to boot again! Only I had no root anymore, so I tried to boot into recovery and there was none. So next I tried to boot into bootloader and when I select fastboot, the tablet says starting "starting fastboot download protocol" but after nothing else happens. ADB looses it, and it just stops right there.
The good news is that I can still use the tablet, it boots and everything works fine but I have no root. I have searched and read and searched and read. I don't know if the reflash flashes the bootloader but that didn't seam to have any effect. If anybody could point me in the right direction I would sure appriciate the help.
there is a way on the TWRP instructions using terminal when you are in system

No when I try to flash recovery it says waiting for device and nothing ever happens.
I seamed to have got it. I down graded to 10.4.2.9 and back to 13. plugged it to the computer and this time it installed drivers and that time I was able to flash recovery. I don't know what happened and it was probably something that I was doing wrong. But just incase that is what did the trick and it helps someone else, i wanted to be sure and follow up.

[Q] stuck in boot loop / pc not recognizing phone with adb

Hi,
I tried to install a ROM but it got stuck on the white screen with the HTC logo. I tried to do factory reset but it gets stuck again. I don't have clockwork recovery, and I rooted my phone using adb and ace recovery, which is not on my phone. I only temporarily used it to flash my rom, stupid I know. :-/ When I connect my phone to the PC it is not being recognized. I tried putting the PD98IMG.zip file on my sd card but it just says that it the image is incorrect. Is there anything I can do? Is this fixable?

I just went through some similar stuff. What type of computer are you using? PC/Mac? Are you using the original cable? What troubleshooting steps for connectivity have you done? Different cable? USB port?
Can you access the bootloader screen when you pull the battery and reboot while holding the volume button down and holding the power button? By accident, I found that the phone and PC will communicate with each other when "Fastboot" is selected on the bootloader screen (you should hear a connection chime and it should change to "Fastboot USB") except I could only get fastboot commands to work. The good news is that should be enough to flash a boot or whatever else you need to get back in business.

Hi, Thanks for the reply.I am using windows 7. I downloaded the drivers for HTC, and I am using a data cable and the USB port in the back of my computer, nearest the mother board. I do see "Fastboot USB" on the phone but when i type in the command prompt "adb devices" I get nothing.

That's great you're getting the fastboot usb message! As long as you're not using a hub or some other usb extender, any functioning usb port on the pc will do. Again, I learned this by accident (ie the hard way) and found that in this mode, only fastboot commands will work, not adb. (on a side note, and others should correct me here, adb and fastboot work together when the phone is rebooted normally or in recovery but not in the bootloader screen)
Great test for connection: fastboot devices (if you get anything else except a serial # with fastboot after it, then close the cmd window, unplug, and pull battery/reboot to bootloader), fastboot reboot-bootloader. Once it reboots back into the bootloader screen, make sure you press the power button while fastboot is selected and you should again hear the chime and see fastboot usb come up. This is your phone saying it's ready to accept your fastboot commands.
Do let us know how it works.

As far as I know, fastboot only works when your phone is in fastboot mode. ADB works in recovery or system.

Flash a rooted stock ROM from recovery. Whether you have root is in your system partition. Whether your bootloader is unlocked is in your bootloader. Whether you have a custom recovery is in your recovery partition. Three separate things.
As for your post in your other thread, read my signature.

I'm guessing that you're trying to flash a PD98IMG.zip or a RUU. You need an actual stock rooted ROM, probably from here on the forum. Or just flash Android Revolution HD, an optimized rooted stock ROM, also from here on the forum in the development section. For more specific steps read the Ace Think Tank linked in my signature.

Dear friends,
I have this problem: I got a brand new TCL S720 and the Google Play did not work, being a known rom issue. So, before doing anything, I've managed to make a backup of it's original rom with MTK Droid tools whichI supose it did it well. Then I've tried to install a CWM recovery to try a custom rom for it. The CWM recovery seemed to install succesfully but I didn't manage to install the new rom. If I remember well, it stucked on boot logo. Then tried to revert at it's original stock recovery, managed to have the phone back as it was in initial state, but doing more tries, It remained stucked on boot logo. The problem is that my computer doesn't recognise it anymore, when I connect it to USB it tries to install MTP usb driver but even before the driver was installed well, now it refuse to install, like the driver is not good or the proper driver doesn't exist. So the only thing I can do is to boot on stock recovery but even I tried to copy the original rom update.zip on external SD and to flash the phone using install update from sd card in recovery mode, It doesn't find the external sd card. So I'm stuck here, the computer doesn't detect the phone to try flashing it with SP flash tool or MTK Droid tool, and I also can't flash it from sd card. Have you any idea how to make it work again?
Thanks in advance.

Please help me out!!!!

Sorry for my bad English. I know is a post about this , but no solution founded! I wiped my cachel/dalvik/data and Now I'm stucked with TWRP 2.6.3.0 boot loop. My tablet doesn't mount! I can go in the fastboot with adb reboot-bootloader. Fastboot work but it stucks and sending or reboot(and if i force reboot my tablet goes in twrp boot loop).I flashed Nv but I couldn't extract that blob. The custom recovery for twrp says something about saving in the intenet server. Please help me out! Sorry for my mistakes..

That's not nearly clear enough for someone to come in and help. Why don't you recount exactly each step you did and what happened at each then. What is a TWRP boot loop? Does fastboot recognize your tablet (does it return a serial number when you inquire?)? When you tried to send, did it say ok? Or wait for device? NVFlash: Are you on CWM recovery now? NVFlash doesn't run on TWRP! Saying "twrp says something about saving in the intenet server..." confuses me.

Let's recap: I'm running TWRP. TWRP boot loop means the tablet continous boot into recovery.The only way I can acces fastboot i by going in recovery and than using the adb reboot-bootloader command in my pc. When I type fastboot devices gives me a serial number. The flashing procces from fastboot is preatty annoying because sometimes says OK erase , sended , writed(sometimes the writing procces take 2-3 secconds)Sometimes gives me errors such as many links. When I flashed NVflash that Root recovery from NV says something like: The bloobs were uploaded to the server!
Thanks anyway! I managed to delete the bootloader and the bad recovery! After that I flashed 2.4.40 and after the 2.7.0.1 . Now I'm running CM! THANKS:laugh:

Help please. Im desperated

Hello
I bought a Huawei x2 and brought a Chinese rom that gave me many problems.
I tried to ask him for updates using the "dload" method but he gave me an error.
The fact is that I formatted it from Flashtool thinking that I had the bootloader open.
After trying everything, he discovered that the bootloader is closed, but now the phone does not boot because I think I have flashed the entire system.
Flash a recovery, it makes me ok but then it does not pass Huawei's logo.
I guess without opening the bootloader it will be impossible to fix it.
I can access the Fastboot mode but I do not know what to do.
I also tried to flash img from the Huawei Extractor, which had previously worked on another X2 that I had brickered.
I guess without the open bootloader it's impossible to do anything.
I need your help. Thank you
Checked in fastboot, bootloader is unlocked.
But I cant install Twrp
I erase system, boot, user data etc

Flash this boot.img in fastboot which should still work. This boot.img is from B212 but should work on any B2xx rom. I'm not sure how else to help you when I don't know much about your device.

Thanks ,but now I dont have access to fastboot mode
You have to use a usb cable and connect your phone to your PC first.
Then press volume down first + power to boot into Fastboot.
I know how use fastboot but now phone cant enter in fastboot..
Boot from B212 dont work

I don't know how else to help you. If you want to ship me your device Ill get it working for you and ship it back. You should always be able to get into the bootloader to run fastboot commands.
Now I can enter in fastboot.
I tried ALL but dont works.
