USB debugging is switched off. I can access the bootloader. I have WUG's toolkit installed, aswell as "Nexus7_Restore". I have got no idea what to do. been trying for 5 hours to fix this crap, no success. if theres anybody out there who shares sympathy and can help me i'd appreciate it ;') Please help, thanks:crying:

Urgent or not, bumping your thread after only 15 minutes is ridiculous. Give it at leat 24 hours.
Moved to General Q&A which is a more appropriate section for a basic question, and it will also get more exposure there.

Hi,
have a look here:
h**p://wiki.ubuntu.com/Nexus7/Installation (sorry, I can't post links by now)
The next to last topic says how to reinstall the stock rom using fast boot mode.
I think this method requires you to have linux on your pc
regards

Hi,
Please can you describe with more details and clearly what exactly is your problem?
Apparently your device is a Hewlett Packard Slate 6 voicetab - OS: JB 4.2.2
Is your device rooted?
Last operation made ?
Don't forget that you need to be more explicit when you need help

Can you tell me where have you downloaded your rom?
And apparently,you have changed the governor and the frequencies of your kernel.
The only solution is to use your nandroid backup for restore your last version.
I'm really sorry but we haven't forum or thread about your device.
I will tried to find something for helping you

i download the rom from the official HP support..(sorry i cant put the link bcause not have 10 posts)so i attach a screenshot.
i dont have back up from nandroid..im just change it and reboot the device..so i dont have the backup :crying:
yeah i search it but no one in the forum talk about this device
apreciate it for your help sir :good:
You need to post the URL of the HP site. Also, without a backup it's going to be pretty difficult. You're going to have to find the factory image somewhere on the web. You did some pretty serious modifications as Ikuza27 eluded to. Good luck

I'm really sorry but I cannot help you more. I've tried searching a link for a factory image or something that it can help you, but except the HP website for support, nothing.
For your next device, don't forget to do a nandroid backup before to do something.

[Completed] Unknown network error on downloading file

i have been looking for the repair/backup of my root on my Cherry Mobile Blaze 2.0 cause i accidentally full unrooted it using SuperSU application, and then i found this site. and i feel so lucky that it has the most normal/simple tutorial on how to root my device again . and when i download the file about 400++mb, it only says Unknown Network Error, and i tried it for about 4 times. the picture is attached on this thread.
Note : my network is all well, honestly i just downloaded other file from google drive too, and everything is perfect.. so i thnk its not the net.
This is what i want to download .. (forum.xda-developers.com/showthread.php?t=2746658) <-- remove parenthesis
PLEASE HELP ME... I NEED TO DOWNLOAD IT AND ROOT MY PHONE AGAIN..
FOLLOW-UP QUESTION
is it possible to reroot my phone from this procedure.
Well even if you've lost root on your current ROM, that doesn't matter as long as you have a custom recovery like CWM. If you know how then just flash that ROM, but being as you have no device specific forum you should post your question in the thread you linked me.
If you didn't understand any of that, then follow this guide HERE. Good luck.
the one you link to me is for CM Flame 2.0, my unit is Blaze 2.0, is that the same ?
im sorry for being noob but i dont know have any familiarity on the term ur giving me . you mean if i have my CWM on my Recovery mode .. i can just click that and then *bang* im rooted again with my system being reset ?
Thanks for your time and effort on helping me ! i'll expect a reply. TY

The zip is just a generic superSU update zip. It sounds like you have a recovery in which to flash the superSU zip anyway, so yes you may just be able to follow that guide. It won't break anything if it doesn't work though. If you need any further help then you should post in the Android Q&A section. Good luck
sir, i just found out that i have what u called CWM in recovery mode. does it help.

I can't give you technical help (read the 2 stickies), although I'll answer you once and say yes it helps: I highly recommend you read up on stuff abour custom recoveries, kernels, etc. To gain better understanding. I've given you a guide to follow HERE and directed you to the correct place to post further questions HERE. If you are still in doubt despite reading carefully through the first link then you should post in the second link where there are many more helpful members who may even have experience with your exact device.

Hi, and thank you for using XDA Assist!
I'm interested in what you mean by "crushed." Sounds like something physical was done to it.
At any rate, unfortunately, we currently do not have a forum (or a tag) for your device. but there is a general-purpose thread. Please go ahead and register for an account, so you can post i other forums. From there, you will probably have best luck with the foll.owing thread:

Hope this helps, and good luck!

Yeah, it sounds like the internal memory got borked, and without adb your options are quite limited.
As mentioned before, I would explain your predicament in the above thread (I see you have posted there already, can just edit the post to add the predicament). There won't be much of an audience, but it is better than the general help thread (and you have the advantage of bouncing ideas off someone who has the same device as you).
Hope this helps.
Thank you.

Today i got one of my friends phone(same as mine) and i did a back up work from system recovery mode and then used it to restore on my phone but an error occured again saying 'checksum compare fail' when i tried to restore the back up file. And by the way i am not sure how to use the ADB so can u help me send an easy steps to use it? Or maybe a link to it will be good enough.
With all my heart i thank you for your kind support.

Not sure about the checksum compare fail (sometimes backups are specific to the serial number of the device), but here is info on adb:

[Completed] flashed with CMOD13 but root again by using OneClickRoot and now having bootloop

Im new in android rooting. I flashed CMOD13 into my LG G2 yesterday night. But the phone showed me I don't have root access. I don't know there is a root access in the developer options ( it's too late to let me know about it ), i rooted the phone again by using one click root and now it's stucked in the cyanogenmod logo and never turn into normal boot after 4 hours. I cant even get into recovery mode. Anyone can help me to solve this problem? :crying::crying::crying: All I need is just get into recovery mode, then I think the problem may be solved

Boo loop issue

Hey everyone,
Up until recently, I've had no issues with my Zenfone 6. However last night the camera started acting up when I was trying to take a picture and the app suggested I restart my device inorder to rectify the problem. I followed the prompt and ever since last night my phone has been stuck in a boot loop. I have stock everything on this phone, I have experimented with roms and kernels in the past but didn't feel the need on this phone. I followed deadman96385 guide on how to unbrick your Zenfone but still have the same problem. I can't enter my recovery instead it just kicks me back to the boot screen. Unforchuntly, it is not unlocked so I have no way to flash twrp and install a fresh version of Android. I contacted Asus and their support suggested I find a local technician but I'm hoping git won't have to come to that. Any help would be greatly appreciated!
