Hi! I was using my N7 3G reading the news and suddenly it became unresponsive. It took about 2 seconds to recognize my touch. So i decided to turn it off and turn it back on. But after it turned back on the touch screen is completely dead. I can't even unlock it. Power and volume buttons still work. I'm on CM 10.1.3
I even forced reboot it many times by holding the power button for about 20s but that didn't help. Anyone ever had this issue too? It seems like a hardware problem. If that's the case i would have it repaired by ASUS but I'm afraid that I won't get warranty because I'm not on stock ROM+rooted+unlocked bootloader
Can you get into recovery? If so, try wiping the cache partition first to see if that helps.
If that doesn't help, do you have usb debugging enabled? If so,
should be able to use the Nexus 7 toolkit. Just boot your tablet, plug it in your machine, fire up the Nexus 7 toolkit and have it unroot and relock your BL.
You might also want to try and see if you can backup your data partition and your internal storage with the N7 toolkit. If you can do that, then you won't lose any of your data or application settings.
You should also be able to flash it back to stock as well via the toolkit and have it erase the user data.
If usb debugging is NOT enabled, then you might be hosed. You could at least do a factory reset in the main recovery.
Other than that, not much else can probably be done unless you want to open your tablet yourself and ensure all the connections are tight. There might be a lose connection for the digitizer and that's all you would need to do to fix it. Of course, that voids your warranty if you open it yourself. I don't know exactly where the hook up is. I'm sure a quick Google will tell you how to fix this if it's possible.
It definitely sounds like either your digitizer is bad or it's got a lose connection.
Good luck!

thanks for your help. I was going to plug it in my PC BUT IT'S WORKING AGAIN. I was like WTF lol :laugh: . So it must be a lose connection i guess .
By the way, I'm planning to go back to stock in case it happen again so that i can get my warranty at ASUS. And I don't know much about rooting/ flashing so I want to ask some questions .
1. Can I flash google's stock ROM just like flashing other ROMs like CM with bootloader unlocked?
2. Have you tried KitKat. If so have you experienced battery drain? The only reason I rooted and installed CM is that I hate the battery draining issue. I had it since I updated my N7 3G to 4.2.2 and it kept happenings in 4.3
Anyway thanks a lot :good:
So far no major issue with battery and yes flashing process is the same just be careful u need to update ur bootloader to go to 4.4 and flashing wrong bootloader will brick ur device to be careful and read every thing.

Well, I used wug's nexus root toolkit to root and unlock bootloader. If I use the option:"go back to stock lock bootloader and flash stock", can I install update from OTA like normal again?

YES
I've rooted with King Root. Since I have got troubles with GPS and need to send phone for repair, I need to completely unroot with no trace that phone was rooted. Do you know hot to do it...? I've found that after unroot via King root RW is still mentioned while booting, so it's not clean unroot... Please explain if you can step by step.
Thank you very much.

Can you just do a factory reset from the recovery menu? Before I bought mine on Ebay I asked the seller about rooting and what if it bricks, he just said I can send it back within a month with no questions asked more or less.

Didn't try yet, in the meantime rather asking. Now did Nandroid backup and trying to find out if I can flash it without root in COS recovery or need to root again, install Nadroid backup and restore vie this app.
Also in Nandroid backup is missing script for Lenovo ZUk Z1 and no chance to find it, so I will cross fingers that it will not cause additional problem during recovering from backup...

Tried factory reset and full wipe and still not updatable, OTA update ends with same log "system was RW mounted" so it seems it's irreversible if you root. Very bad news, so you can't then apply warranty.
Do you have anybody advice how to reset into facotry default without any trace device was rooted..?????
You could try this toolkit, but you will need stock rom. http://forum.xda-developers.com/zuk-z1/development/win-zuk-z1-toolkit-0-1-alpha-t3235964
So it seems, it's not possible to make safe root and unroot on ZUk Z1 device as far as I know. Maybe somehow very difficult. That's not great news indeed. It's my first phone ever not possible root / unroot safely. And it's giving me feeling that Z1 despite it's great device in terms of hardware is not good choice. Also quite surprised how far away from well tuned OS is current release. I can't understand, why just CM didn't develop OS with possible root right or didn't incorporate full device backup. Honestly I don't care so much and probably neither other users about root, if natively in OS is complete backup / recovery. And... If I can do root without possibility go back (reclaiming warranty or not functional OTA update), then it makes me think, if really Z1 via CM is good choice or not. Despite really nice HW and materials... Pitty

No you should have read how to do it before you touched the phone. XDA is not a spoon feeding centre. It's for people who want to help themselves. If you had done the reading and had an issue with getting a part of the process to work, yes, but to blindly rush in and want it sorted out because of your own +++++ I must sound like a #### but you learn then act. Everyone has 4 posts and a screwed up phone wanting help. Errr there is a link between the two.
1.Flash a clean COS image via Twrp
2.Flash a clean COS recovery via twrp or adb sideload
3.Lock the bootloader
Hi there! I've always been a Samsung user and I'm familiar with chainfire rooting method, Odin, the damn knox and all the tools that people need to achieve the beloved full control of our phones.
Let's go straight to the point: I need to buy a new phone for a friend of mine and the P9 Lite seems the most complete and suitable but I've read that if you unlock the bootloader and root it you obviously loose your warranty. The phone is unrootable by flashing a fresh OS image, but the bootloader will stay unlocked, tripping the useful warraty.
Is there any damn way to revert everything to stock in case there should be the need to send the phone to the customer service?
Thanks for the infos!

You can relock the bootloader if you reinstall a stock rom and revert to stock recovery, just fyi... Also there have been reports that the warranty is not void if the issue was not caused by a faulty software. Also if you are new to Huawei, be careful. And READ! A lot of people don't read, and mess up their phone...
Instead of making a new thread about the same issues I'll pitch in here too. What is the safest way to root and unroot in case of warranty? LIke the OP I came from the Samsung ecosystem too but I get the feeling if I don't at least ask about Huawei's one I'll probably **** something up.

Simply flashing stock rom will lock bootloader but Huawei have your data of unlocking bootloader.

That way you could say that when i get the code, i void my warranty without actually unlocking the bootloader...

Huawei says they "could" apply fee on unlocked phones. Maybe relocking it restores warranty? I tried to ask them but damn Chinese they don't reply.
They could, but the chance of that happening is really low, especially if your device is 100% bricked, and it needs a motherboard swap

If it's hardbricked and bootloader is unlocked and the problem is not related to bootloader or a process you made that requires unlocked bootloader, I think they won't fee you because it has nothing to do with bootloader. But of course a company will always choose cheaper way. If a phone goes download mode or fastboot mode it's already saved anyway.

I wish... I can't seem to be able to save mine, even though it shows up on fastboot on the pc. The phone itself won't turn on at all. I can't seem to lock the bootloader either, anything I flash now seems to have no effect. I just hope the Huawei service fixes it.

If you have access to fastboot mode, you can flash anything. You dont have to flash an img permenantly if you want to save your phone. Use
Code:
fastboot boot boot.img
you can boot your recovery without rooting your phone. You can even open your custom recovery and flash your system.img or stock boot.img.

I tried fastboot flash boot boot.img (and similarly, recovery.img, system.img, any partition I could flash, multiple times with multiple files) but the phone did not boot at all. Not even into the bootloader nor recovery. It was completely unresponsive. Now the phone is not in my hands so any suggestion is too late...
Welp, my power button has decided to do some funky things lately and I decided to RMA it. Just wanted to double check on the steps to bring it back to stock. First, download an official RUU and flash it to the phone. IIRC this will also bring back stock recovery which will replace twrp. Then lock the bootloader and then go back to S-on. I sent my phone to J-case before unlocking was available on Sunshine, so is there anything special that I need to do to lock the bootloader and go S-on? I will be following the steps outline in this guide to help me out https://theunlockr.com/2016/08/18/unroot-htc-10/. With that being said, is there anything special that needs to be done that this guide does not outline for our phones? Also, if my terrible googling skills missed a thread that already has the steps outlined, please link it to me and after I get the phone back to stock I will then delete this thread.

Honestly, if you are just returning it and anticipate a replacement warranty device, as opposed to a repair, just factory reset it and don't worry about it. They're not even going to power it up; they'll bulk erase it and reflash it and nobody will ever know it was S-OFF and/or bootloader unlocked.

I kinda figured that is what they would end up doing with it. But I also did not want to go through the headache in case they decided to check. Thanks for the advice!
Hgol is probably right but when I was on the phone getting my device set to be replaced they told me that if the phone was physically abused or had software modifications they would charge me a 300$ unrefundable fee so for me I ruu to stock and went back to s-on locked to be safe I would too you never know if your device is gonna be that one that they actually check
If my bootloader was unlocked and had Fulmics Rom on my LG g6, would LG repair a cracked screen if it were to be broken?
LG G6 H870
They will be assholes about it.
I do a lot of repair work for Samsung, Apple, Sony and LG and all of them will try and get out of a warranty repair.
Just be safe and backup to SD, flash stock, lock BL and send off for repair.
When you get it back use the all-in-one tool to unlock and restore backup.

Oh fair enough, also 99% time they wont fix a cracked screen, as they don't crack on their own. If it was blank or non responsive they might.
They would never repair a damaged screen, with or without bootloader unlock.
But if you have a problem with your phone that is covered by the warranty, don't forget to re-lock your bootloader before sending it.
Ok thanks for your help again!
