I was in the process of taking my Nexus 7 back to stock yesterday it started giving errors from fastboot. My device is completely wiped clean. Can't boot into recovery since there isnt one, there is no system to boot into, etc. I tried to install 4.2.2 via the toolkit and manually from fastboot and I keep getting errors. The most recent one is no such device or address found. The only the only thing that I have been successful in doing this entire time is oem lock and unlock. I read somewhere else that someone had a similar issue and that fixed it. I have tried every different port on my laptop and every different cable I can find. I haven't used the OEM ASUS cable since i cant find it, but I think it is at work so that the last one I can think of.
Can anyone offer any help or solutions? I've had the worst luck int he last three days with my devices. I've never had a potential bricking issue since my G1 and now i can't seem to avoid them. Any help is greatly appreciated. I can provide screenshots of the errors if that would help as well.
EDIT
Turns out it wasn't a bad device or any of the million cables. It was a bad laptop. I was finally able to get the drivers to install on my win8 desktop and it all went as it should.
Hello all,
I had an old phone lying down in the drawer for a couple of years and I decided to use it as my sports tracker. But I happen to notice that, my cute little phone had alzheimer and forgot it's name. Heck, even it's mac address and so on.
The version looks like it's the same with D290N just with a local patch.
The one that I found on XDA is a link for MIUI devices. And the other resources (other then xda) on the internet involves only shady stuff for duplicating IMEI and so on. I actually paid for this phone, and I want it to work. I don't want to deal with those weird "hacking" tools or download some random zip with malware in it. The only source I'd be trusting is from XDA.
Here's what I've tried to do
I tried to reinstall the OS with entering serial and the IMEI (I still happen to have the box) on the official LG software tool thing. Yet I still could not get it updated. The update stucks and tells me that it cannot connect to phone (which is connected already and debug mode is on)
So I gave up my warranty and give it a little go with the purple drake tool. Right now I do not even know if the device is rooted or not. It cannot go online because it does not happen to have a mac-id.
I tried to factory reset, factory reset on safe mode, hard factory reset both got stuck on the "restoring" phase. I left the phone overnight while plugged at charge. Logically it shouldn't take more then a 5 minutes complete the reset
I used to install custom roms on Nexus devices but I'm really clueless about non-nexus devices. What should I do? Please mind that I'm not a developer and I'm not used to with this rooting stuff.
Thanks in advance!
Hi all,
I'm just about at my wits end here. I have a Note 4 (N910W8) with a failed USB connection and I would really like to root it. The underlying goal is to remove/disable all samsung bloatware.
WRT the USB, I have tried adjusting developer options, *#0808#, updating drivers, changing cables, changing PC's, etc. I've tried everything I could find online. Recently, I took it to a local shop and learned that the problem is not with the USB port/board, but the motherboard itself. I'm not going to pay to replace it. I have googled far and wide. As far as I can tell, this phone will never again connect to a PC via USB. So, download mode and Odin are out.
I have tried TowelRoot, KingoRoot, and other apk's, but I am on Android 6.0.1 (MMB29M/GLW-N910W8VLS1DPK1) so all of these exploits have been patched.
I am able to boot into (stock) recovery mode, so I thought I'd try recovering via SD card, however that doesn't work either. First I get a loading screen of the mascot with a spinning wireframe polygon in his belly and the message "installing system update". Then after ~15 seconds, the mascot is on his back with a red warning symbol over his belly, and the text "No Command." is displayed. I'm not sure what that's all about, because I have the latest update installed.
Any attempts to install CF-Autoroot or another recovery firmware (ie https://samsung-firmware.org/model/SM-N910W8/region/GLW/ , or https://forum.xda-developers.com/note-4/snapdragon-dev/trltecan-n910w8-aoa1-stock-rooted-t3025538, etc) from SD (in recovery mode) have been met with the same error messages:
E:footer is wrong
E:signature verification failed
I'm not sure why because at least some of these recovery firmwares claim to be official builds. Granted, they are older versions (downgrades), but are signed nonetheless.
I have tried installing TWRP or CWM so I can disable signature verification, but AFAIK the device must already be rooted to install these (which seems like a bizarre catch-22, but maybe I'm confused) so that's a no-go.
It certainly feels like I have explored every possible avenue, but I have one remaining idea. Perhaps if the phone doesn't want to downgrade, I could force its hand by carefully soft-bricking the current rom in a controlled manner, then performing a recovery from SD with an official 4.4.4 KitKat build, and finally, using the towelroot/kingoroot/etc exploit to gain root access.
I mean, why else would there be a recover-from-SD option in the stock recovery menu? There must be a way to get it to accept a recovery build...
It's a last resort. But I'm willing to try it. The phone boots up, but is so bloated and laggy that it's practically unusable. Still. Am I missing anything? Surely there's some way to skip the USB / Odin method. What do you guys think? Is it time to go hulk on this thing? Is there any hope left? Curious to see how much further this rabbithole can go.
Cheers and thanks guys.
I've searched for ways to soft-brick, but have not come across anything. The bootloader appears to be locked, which is odd because I thought that only applied to Verizon variants.
I have recently downloaded an ADB/fastboot package for windows so I could attempt ADB over WiFi, however I can't establish a connection. I thought I'd do some more poking around on the phone side, so I installed some Wireless ADB apps. They all indicate a root is required, so I think that might be a dead end. I also connected to a ubuntu machine. Nothing. The phone charges, but both the PC and Ubuntu machine show zero signs of any connection at all.
There has to be some kind of SD-based solution to this. You can boot a computer from an SD card / USB stick and use that to access files (on an unencryped partition), and I'd be happy to do that here and delete those bloatware APK's directly... but I guess phones don't behave like other computers.
I've picked all the low hanging fruit. A part of me believes that there are some sneaky hacker ways to get at this without USB (ie some sort of rootkit) but that's way beyond my abilities. I'm going to take a break and attack this again once I have fresh ideas.
I'm in the same boat (busted usb port), does your phone still fast charge? Mine stopped fast charging.
I too have the same problem, except with the Note 10.1 2014. I know that is a different forum, but if you find a solution, it might be adaptable to my problem. I too have exhausted all other options as described above. Please someone, there must be a way to root via SD card instead of Odin. Help us please!
Me too. I have a Note Pro 12.1 running Lollipop. USB is busted and I've already replaced the port and ribbon, so it must be the motherboard. I mainly need it for Titanium backup, so I don't have to reinstall large games over my limited connection.
I have the same problem. Note 4 N910H. Not recognized by pc, stopped fast charging shows usb charging in battery settings. AFAIK I just re-rooted the phone before it went bust. There is no solution except changing the motherboard. Also this problem seems to be quite common.
Hi there
I'm not sure if my phone has a hardware problem or if I've done something stupid earlier in the year. I flashed the 'CRAP' Odeo to my phone ahead of general OTA release. I should have known better with the build tag but there you go.
Phone's working fine apart from poor battery life, and now it seems that nothing seems to communicate on USB! I plug it in, and it will charge from USB but that is as far as it goes. What has transpired though is I'm not getting OTA updates so I decided to just restore the phone to stock with Smart Switch which then lead me to discover the phone isn't working over USB.
I can change the mode between MTP/PTP/whatever in dev options and still nothing detects on the computer it is plugged into. Trying to do ADB results in nothing, even from the recovery loader (selecting ADB just reboots the device).
So I am not sure if I am missing something obvious or if there is a hardware fault with the phone. Not a problem if there is, as it is still in warranty/showing as official/in warranty on the phone but I'd rather not take it in for repair if I'm doing something stupid.
So tl;dr: flashed pre-release Oreo to my phone (CRAP build), want to restore to latest official stock, can't because not detecting in either adb/odin.
Any ideas are well welcomed
Cheers
Hello everyone,
My old S10+ suddenly shut down and entered a bootloop. The last things I did were the following:
copied some data from my old to my new phone
Switched my SIM-card to my new phone
watched some Youtube in my browser (since stock had some issues)
Then, out of nowhere, my android system turned off. Since then it is stuck in a bootloop.
I can still access Android Recovery and download mode. I tried re-flashing stock firmware, but I get the error that the Android firmware seems to be corrupt.
My question is: How can I get my phone to work again without losing my data?
There is still some important data left on my old phone. My 2FA app for instance. So I would rather go to a repair shop and pay instead of losing said data.
But before I do that I wanted to get some advice what else I may be able to do. I haven't tried sideloading an OTA since I don't quiet understand it and want to be on the safe side. persist.safemode.sys does not seem to exist. And I read about perhaps backing up my "emmc" with TWRP but, again, I don't quiet grasp the concept yet.
I have some experience with adb, ROMs and flashing. The latest recovery-logs are attached, if they are of any help
Well, repair shop went and formatted everything
Even though I asked them not to
Let this be a lesson for everyone: If you care about your data, back it up AND don't bring it to a repair shop

In the future use a SD card* as a data drive. All critical data goes there. Do Not encrypt it.
Had you done that you probably be ok. Always backup redundantly and regularly to at least 2 hdds that are physically and electronically isolated from each other and the PC.
*A V30 rated Sandisk Extreme is a good choice
