[Q] Nvidia Shield black screen on boot - Shield Q&A

I rooted my Nvidia shield a day or 2 ago and everything was working fine, until i i went to the play store to look for some apps. it wouldn't connect. i tried everything anyone suggested and nothing worked. i tried completely resetting the whole thing. that didn't work. then i found a guide at http://forum.xda-developers.com/showthread.php?t=2110225 and at the bottom he explains that if you delete Hosts file under system/etc/ and reboot and Wipe Cache/Dalvik Cache. well i ended up deleting the whole system/etc/ folder. i so dumbly deleted the whole thing and now my nvidia shield will not boot. it gets stuck on a black screen during the boot process after the nvidia shield thing comes up. i tried reflashing the root_shield.img, i tried the recovery options and thats not working. please help me
Thank you.

Man I'm sorry these guys on the forums are ignoring you, try shield ram, restore bone stock, and it should work, I hope you can still boot into boot loader, if I were you I would have gone nuts, especially when you come back emty handed after asking the forums, just wish there was a better averting questions implementation on xda, its like once your question is ignored for a week, its done for good, hope this help tho

[Q] Important Help please. Nexus One Rebooting

Hi, I'm quite upset and I don't really know what to do. You see, I bought I Nexus One and since I'm a computer tech (Network is my strong point and I also got a Professional diploma of informatics support)I thought I could go and mod my thing out. Thing is everything worked fine until I downloaded Cyanogen with Rom Manager Premium (Crack3d)and tried to install it. At first it simply shut down the screen, rebooted a few times and restarted normally, then I retried downloading and it brought me to the reboot in recovery mode to install cyanogen popup. Clicked ok and then it rebooted another 3-4 times and when it came back, it was cyanogen splash screen bugging and rebooting in the middle of the loading. I have Android SDK if that changes anything, I just really don't even know how to bring any sort of menu from my pc or my phone.
P.S. I didn't cleared cache and didnt do any backup[thats no that important].
Thanks

First, please don't double post. You don't need to start two threads for the same problem.
Second, I'd start by searching the nexus one forum, reading through the wiki, then, if you still have questions or need assistance, posting in the nexus one q&a forum.

What's this 'cracked' thing you mention? I truly hope you're not saying it was a warez copy that you downloaded to avoid paying for it? The App developer posts his work on this forum and would just love to meet you!
You started flashing custom ROMs without doing a backup? Bit unusual for a 'computer tech' with a 'professional diploma' to be so reckless.
Threads closed will deal with it personally

I say you needed to use the g2x android development forums on this site to find a suitable jb rom, not this other site. The one click method isn't very stable, so nvflash is most definitely what you need to try to get working. There are very thorough tutorials on how to get that to work. Do you know which clockwork recovery version you have installed? Should be 5.0.2.0. Once you get home, I suggest you read read read. Do as much research you can to make sure you can follow nvflash instructions to the letter. I know I personally spent about a week researching to make sure I had a solid understanding of the procedure.
I recommend getting nvflash going to get clockwork properly installed, then download a rom from xda, nowhere else. I would even say use a gb rom before trying a jb ...the jb roms are hackfest versions, so they have (from my experience) much poorer battery life, and lack hardware acceleration. Netflix and many 3d games won't work. You can use adampk or mazout's roms but they don't have working radio, i.e. no phone/SMS functionality.

Boot into recovery, there should be an option to format or wipe system. Do that then flash the ROM. It won't boot if you flash it over stock.
Also, use the paranoid android rom found in the development section, same cyanogenmod base but works better.

Ok, wait I think I understand what you're saying now. If you can, pm the op of that thread you used to unbrick. Ask that person if you need some kind of different file in that .zip file to work on your carrier.
I remember having to use that guide to get back to stock. Glad to see you're making progress. I know it can be frustrating when devices get wacky. Good luck!

hehehe sorry, I am not fully used to the right terms so I rather stay in the gray zone by using words like ''thing''
but I can now oficially say I was talking about ROMs
finally, I managed to bring back my phone to the stock mode everything seem to work!
now I can brick it again!
thx for the help!
I began to wonder if it was just a matter of changing APN settings?

[Q] Nexus 5 Stuck in Recovery and can't mount on Mac

HI, I love learning about my phone and wanted to gain root access and have clearly made a HUGE meal of it. I desperately would love some one to explain if I can save be beloved Nexus 5.
When turned on it loads to the 4 colours and just wont go past that stage. I can access recovery mode but it wont mount on my Mac so i can access the SD card.
I'd just be happy to reset my phone now to factory can someone please help me do that!!!!
Thank you VERY much to anyone that could explain to me how....
Recovery doesn't mount storage. Google "adb on mac" then learn to configure adb.
Sent from my Nexus 5 using Tapatalk
It is hard to know the best way to fix your issue, because it isn't really clear what you have done and when the boot looping started. I think that what you need to do is to reflash the factory firmware and that will require you to set up adb and fastboot correctly (as mentioned in the post above). This tutorial and this begginner's guide are probably a good places to start. If you don't understand something, search that thread and look in the "stickies" in Nexus 5 General...if you are still confused go a head and ask in the most appropriate guide thread or in the Nexus 5 Q&A thread.
i highly recommend WUG's nexus root toolkit.
this have saved my ass many times.
http://forum.xda-developers.com/goo...olkit-wugs-nexus-root-toolkit-v1-8-0-t2517778
but you must sort out your ADB problems first.
many ppl have run this on Parallels or WINE, or borrow a PC from somewhere to restore to stock.
Never use toolkits! They tend to do more damage than good.
@thegrapher : Go to stock recovery and do a factory reset and see whether the phone boots or not.. If it doesn't, do what rootSU suggested and setup adb/fastboot on mac and flash the stock factory images!
Thanks heaps guys....really appreciated all the replies. .
Firstly, thanks for the advice i will avoid toolkits in the future.
However...i did manage to sort it out i think. All seems ok so i hope so. Yeah it was loading the google screen showing the padlock on the bottom but the four colours just bounced on and on and nothing... so i couldnt mount it. I could go to recovery (a teamwin logo appeared so i guess that was installed). but in all the options it had nothing on the sd card or didnt appear to after going into every option and clicking mount or sideload. tried to reset it and finally i formatted decrypted data under that option and boom all good. even got it unlocked and working so i guess i found my way eventually.
Would like to know what i did so i can learn but i feel i went about it in such a way i didnt really learn anything. just happy its sorted i guess. and sort proud it is unlocked now i can move that annoying volume bar to the top where it should be!!! lol
hope some of that made sense or can explain what i did. cheers

[Q] LIkely a idiot noob question, but I dun goofed and idk how ot fix it...

Basic rundown, I bought an HTC One M8 on tmoblie yesterday, coming off an iphone 4. I've heard you have have have to root your android devices, so that was one of the very first things I did. Shortly after, I was trying to figure out exactly what I could do with the root, and decided to flash a custom ROM. I tried the Google Play edition posted on the dev section of this same forum. Everything worked as planned, except for one huge problem: my data no longer works. I can connect to wifi fine, as well as send texts, but no 4g lte access anymore. Idk if this is a common problem, if I'm doing something simple wrong, etc. I made a backup in TWRP, and saved it to my desktop, and tried restoring my phone to see if that would help, but I must have dne something wrong there too, as it doesn't show any files when I try to restore under TWRP.
I would greatly appreciate any and all help or tips. I'm new to the android rooting scene and should have taken it more slowly. I thought I had done sufficient research, but I guess I ****ed the pooch somewhere along the way. Thanks in advance.

Try the Tmobile M8 forum

[Completed] Phone inoperable did nothing but followed steps.

Ok so I am unsure if someone is filtering out OLD topics but i keep coming across FORUM posts from people and it seems like they are getting no help or being referred to NON existent topics.
I just recently bought a HTC ONE M8 H/K from sprint. I have had android for a decade and am seriously tired of the ROOT it people. so I figured why not no down falls and everyone says it is easy. Well I am Murphy last name law and you people have not seen or know the things I am about to post
I recently spent over 32 hours watching video and preparing for ROOTING. I unlocked phone got Pilz touch recovery and everything worked fine. I even got CWM and SUPERSU and Busy box. all of which needed OTHER files to work properly. Again a few forced quits everything was fine.
I wanted to Switch to TWRP and the install didnt go through. however now I have BOOTloop. trust me this is the tip of the berg at this point.
Just short of finding NO help after another 24hrs binge session on the CPU and just shy of RUNNING MY PHONE OVER WITH A DAMN CAR>
I get oh so simple easy fix and the only posts I see are FIXED IT!!! so that helps me approximately as much as my phone helps me make phone calls currently.
After the boot loop SEVERAL friends versed in this so called ROOTING (which I still find to be a hoax and not actually possible by any means at this point and time.) and no one has any clue. Tried flashing ROMS RUU's everything comes back to NO will not work.
Then it brings me to the STOCK RUU config for the HK M8 which seemed like it was going to work through ADB flash but guess what. 2 hrs idle NOTHING. after that The recovery program dropped out and boot loader only stated RUU in the menu. (something never before logged in a forum or post as I can tell) after many attempts to do GOD KNOWS WHAT WITHOUT ANSWERS as i was about to smash my beautiful gold phone into a dozen tiny peices and claim accident the Recovery came back to...... You guessed it NOTHING. All directories are UNMOUNTED and cannot be mounted.
I am stuck. Seriously you all fix my phone or help i am willing to send gifts because I am out 700$ now on this nice paperweight but everything and everyone tells me. OH SO SIMPLE you have recovery it aint no thang.
Well guess what it is and I am tired of being so PISSED OFF for something that was so automated.
Again I am Murphy and what you attempt to get me to follow will come up with some REALLY weird repercussions I will post back.
Please oh mighty gods of ruining my life. Spare me this one thing I will never ask for another again.
How do I get my phone to just WORK, Simple. Right?
Hi there! I think I found a thread that can get you back on track. Please read every word carefully and follow every step. If you have further trouble or want to clarify anything, please ask in the thread. They know the device best and can help you I'm sure.

I'm afraid that is the extent of what we do in the XDA Assist Section. We are guides...pointing people in the right direction when they can't find what they are looking for. Unfortunately we don't do hands on support in this section, so as I said....if you need a further hand, I am sure someone in the thread I linked can help.
And make sure anything you download and flash is for your model. And as always, do a Nandroid backup in recovery... before flashing anything new....it can be a lifesaver to help restore you when you hit trouble.
Good luck!
Details
Let me re iterate.
All guides are demanding S-Off (cannot as I cannot acess phone apps to do so)
All guides need HOME access for apps to modify certain things
I cannot:
Push packet through adb as they are unreadable
Get past boot screen
Recovery is only 40% operational with visibilty of phone only working sometime.
Cannot flash
Cannot push
Cannot fastboot
Cannot see device on CPU as it is stuck in recovery
ALL DIRECTORIES in /SDCARD have been removed
No Firmware
No RUU
No img
As far as I can tell.....Phone is empty and cannot be populated with anythin. I did manage to get SuperSu pushed through and installed. But how do I open it?
No ROOT access as well in the recovery.
I followed ALL STEPS of EASY guides even downloaded one button app that runs it all for me. Can't talk to phone does not see it in ADB.
The other guide I went to was helpful but I have already attempted all of those things.
With an empty phone NO DATA and no ability to get ADB to even run data over cable I am baffled.
I did exactly like the 500 guides i read said.
1) bootlock unlock
2)instal recovery (Philzmod)
3) get CWM (retrieved from playstore) Need a .zip to run in ADB
Phone worked fine until I changed from Philz mod to TWRP which never took place. Philz mod still runs but TWRP said it installed.
Now I have a completely worthless empty phone and I have cried about a tub worth of tears over the 700 i will be dropping over the next year for a piece of metal.
Oh and 99.9% of time if ADB DOES do something either no directory once pushed, cannot read or cannot FIND/Open directory stating BAD installation aborted I NEED a better recovery
I understand your frustration. Not a fun situation at all.
As I said, XDA Assist is here to help navigate the website. Not to troubleshoot I'm afraid.
The purpose of XDA Assist... http://forum.xda-developers.com/showthread.php?t=2764768
The very best place to ask for help in your situation is right here, in the Q&A section for your device... http://forum.xda-developers.com/showthread.php?t=2764768
The people there know your device best. Start a thread that's to the point, polite and accurate....what is exactly wrong, and the exact steps you took to get there. And hopefully help will follow.
Hope it can be solved for you!
