[Nexus 7 Q&A, Help & Troubleshooting] rashaunb:
I know there's already dozens of threads with this problem but I've been going through them for three days now and I've pretty much given up trying to fix this. I'm posting here as a last resort.

All of sudden my nexus started shutting off or restarting and then it froze at the google screen, not the X logo like most people. I went into fastboot and then to recovery then tried the wipe data/factory reset option, doesn't do anything. Left it on that screen overnight and all that happened was the battery drained.

Now I'm stuck with in the android recovery screen because I kept trying to wipe it so much

E:failed to mount /cache (Invalid argument)

E: Can't mount /cache/recovery/log

E:failed to mount /cache (Invalid argument)

E: Can't mount /cache/recovery/last_log

E: Can't open /cache/recovery/last_log

E:failed to mount /cache (Invalid argument)

E: Can't mount /cache/recovery/last_install

E: Can't open /cache/recovery/last_install

E:failed to mount /cache (Invalid argument)

I've downloaded sdk files, images and toolkits. I've done commands but I can only get up to unlock bootloader because it fails. I don't know what else I can do at this point, nothing seems to work. I've watched a video of a guy doing the wipe data/factory reset and it reset in seconds so I'm very frustrated with this thing. It's only 10 months old and I can't remember if I got a warranty or not and I don't even know how long a warranty is on these anyway.

Forgot to mention a couple things. When I try to wipe it, the android is frozen unless I press the power button and volume up again. Then the blue line and the little shape in front of the android start moving. There's no text here and the text freezes on -- Wiping data... Formatting /data and I never rooted it.

I am getting this same issue. The lack of replies is concerning.
[Nexus 7 Q&A, Help & Troubleshooting] Captain Sweatpants:
The reason there are no replies is probably because there is no solution if people can't help they won't comment and clutter up the board with useless posts. Tell me everything you can about your situation is your bootloader unlocked? Rooted? What ROM are you on? Can you access fastboot mode? Ect and I will see if I can help:)
[Nexus 7 Q&A, Help & Troubleshooting] broncop3t3:
I was on cyanogenmod 11 4.4. I had many random reboots and was going to do a factory reset through recovery, it was freezing too much to reset through Android. I used Nexus root toolkit when I rooted/ installed CM11. Now when I try to use the toolkit I get fails and trying though recovery gets me the E: failed to mount errors.

Nexus 7 Wifi (2012)

unlocked bootloader (still shows unlocked on "google" screen

Was Rooted

I can access fastboot mode.

I tried to flash via fastboot and was unsuccessful.

Thanks for your help.
[Nexus 7 Q&A, Help & Troubleshooting] Captain Sweatpants:
What error message do you get when you use wugfresh NRT back to stock and unroot with the option for soft bricked

Edit: It just occurred to me the most common reason for flashing failing or "failure to mount" is a corrupted nand memory, a bit like bad sectors in a hard drive.

Nand going bad could produce the spontaneous reboots and would explain why you are unable to reflash it.

The only option if that is the case is RMA or a new motherboard.
[Sony Xperia Z Ultra] heartless vegan:
If your XZU freezes / restarts while booting, it's probably soft-bricked (in fact it's almost impossible to hard-brick it). Use this guide for a clean restore:

- internal data will be wiped

- no root required

- no unlocked bootloader required

- Windows is required

Download Flashtool: link to krabappel2548's post

Install Flashtool

Install drivers using the Flashtool-drivers.exe which is located inside the "driver"-folder of the installation path of Flashtool. Include the flashmode, the fastboot and the XZU drivers.

Download or build a full stocked FTF firmware file fitting your model. Choose Method A (fast) or B (recommended):

Method A (fast): Download a complete FTF-file from the XDA forum (for example link for C6833 or link for C6802 or search the forum for a up to date firmware fitting your model). Move the FTF-file to the "firmwares"-folder of the installation path of Flashtool.

- or -

Method B (recommended): Build your own .FTF file with the newest official stocked firmware:

Install Sony PC Companion: link

Do not connect your smartphone to your pc. Start Sony PC Companion, choose "Support Zone", start the software update. Click on repair and accept everything on the following dialogues. Sony PC Companion will start downloadng the newest firmware.

When the download is finished, exit Sony PC Companion. Use the search function of windows to locate a folder named "blob_fs". This is the place where Sony PC Companion dumped the downloaded firmware. You need 4 files named "FILE_XXXXXXXXX", which have different numbers and no filename extension. There are two small files < 1 mb, one medium sized (circa 20 mb) and one big file ( > 700 mb). Ignore the ICON_ files.

Start flashtool.

Choose Tools > SEUS Decrypt. Choose the "blob_fs" folder as source. Convert the 4 files. Wait until the Bundler dialogue pops up. Content everything you just decrypted and fill in the three fields (Device, Branding and Version). Click on "Create". Wait until it's finished. You will find your fresh FTF file in the "firmwares"-folder of the installation path of Flashtool. Leave the file where it is.

Now it's time to flash the FTF on your XZU. Start flashtool if you haven't yet.

Turn off your XZU and wait at least 5 seconds. If you cannot turn off your XZU, hold the power- and volume-up-button at the same time for 3 seconds. Your XZU will vibrate briefly and poweroff. Or push the button inside the Micro SIM card slot: link to Kiwi Tech video. If you choose the last method, don't forget to leave a youtube comment on Kiwi Tech's video declaring war on his overlong intro :)

Plug in a fitting USB cabel to a USB 2.0 port of your PC. Do not use a USB 3.0 port. Enter Flashmode: Hold down the volume-down-button and connect your XZU to the prepared USB cabel. You can release the button when the LED lights up.

Flashtool will notice your XZU in flashmode (check log). If not, reinstall the drivers using Flashtool-drivers.exe. Inside flashtool, click on the lighting symbol. Choose Flashmode.

Choose a full FTF firmware & click on "Flash". Wait until it's finished.

Your XZU is now unbricked. Have fun :)
[Sony Xperia Z Ultra] SweFox:
I got my Z1 Ultra today, unlocked bootloader and tried to get root following "[HOW-TO] ROOT 14.1.B.2.257 and poosibly newer Sony Roms"

I screwed it up and the phone boot looped. I now realize flashtool was at fault refusing flashing stuff. I reinstalled it lots and then installed it one more time with version .12

I tried flashing and now it finally flashes the newest firmware!

I guess my phone will be okey now :).

--

Yep, phone works.

Thanks for this thread.
[Sony Xperia Z Ultra] moom999:
If I go with method B how I know that it will download the latest firmware for XZU not for any other sony phone.
[Sony Xperia Z Ultra] heartless vegan:
After decrypting you will get a elabel .sin-file, which includes information about the firmware version (for example "elabel-C6833-row_201310161732.1_14.1.B.2.257_XXX"). During the repairing process of the Sony Pc Companion a screen will pop up and asks you to choose your smartphone modell. But at that point your download is already finished, which is quiet confusing too me. For me it worked perfectly and the built FTF file got the estimated file size (circa 780 mb). Maybe someone can test method B to the point where you decrypt the files and tell me if he got the fitting elabel.sin?
[Sony Xperia Z Ultra] moom999:
So I will know which after it finish downloading. I can’t make it download to exact phone I need FTF.

[Sprint LG Optimus G] criddopher:
Im running treve mod to tether wifi on my optimus g. I have the latest updates from sprint and im rooted on the stock rom. It worked fine for a while.

I then developed an issue when if I was using two conntections *ie, me on my pc and my gf on hers, It would stop working after a while of use. Now I just couldn't visit any new web pages, if I was say, watching a youtube video or playing an online game it would continue to play, But when i tried to visit a new webpage Id get the cant reach server error. This would typically occur after a few hours of use.

Then it progressed to doing this after shorter an shorter time periods when we both use the connection, to the point where we'd both surf for perhaps 20 minutes and It would stop working.

Now its to the point where whether we both use it or not the connection only lasts maximum an hour, sometimes as little as 10 min. Same thing though If im paying a game or on youtube it will continue to play thought but new pages wont load. Its like established connections stay connected but I cant make any new ones.

So, the temporary fix I've found is just the untether wait 5 seconds and retether. Its annoying.

I've tried a few different versions, most recent that I know are 11-22-12 and the one i just installed today is 3.2 beta2 modv5

My settings are what was posted here:

wlan0 (when i try others my pc cant connect)

netd-ndc (master)

send netd cliend cmd ( tried turning this off no change)

wifi driver reload (I tried checking reload 2 in addition to the first, and tried just reload 2, or none checked)

mms clamping

routing fix

Its really starting to become discouraging. I don't understand how it would work fine for a while then slowly and progressively deteriorate. (its been over the course on 8 months or so to get to this point.

soooo I my hope is that someone else has an idea, im running out!
[Sprint LG Optimus G] bruiserman:
I have all the same settings except I have disable wake lock checked. Not sure if that makes a difference. I haven't updated to ZVC yet just in case wifi tether has issues with it. I really want to update just to get rid of the notification. Will be paying attention to see if you get it fixed. My wifi tether has good and bad days though. I think it depends on the signal I get. Where i use it has a weak signal. Sometimes a restart works and other times I fight with it all day. On average though, I can run it all day long without issues. Oh, and I'm using the same version of Wifi tether.
[Sprint LG Optimus G] criddopher:
I have wake lock checked also. Forgot about that.

These tether problems started before the update, I installed the update and nothing changed.

As for your weak signal, I can relate and ill tell you what I did.

I live in the country, on the sprint map I'm outside of 4g service by about a mile. I was getting a 3g signal and almost no bars, Id have to go outside to talk. I got a wilson sleek universal from the 3gstore. (not to advertise any single company you can get em all over) my talk bars went to max with it, and with the little antenna I could get a 4g signal. BUT then summer came and i assume the foliage blocked my signal. I was back to 3g most the time and 4g sometimes. So i got this outdoor universal antenna from the same place. Now I have 4glte signal all the time, ranging from 6meg to 14 meg down, so it works really well. I Just have the antenna in my window too even though its meant to be mounted on the roof.

back to the tethering, I loaded up a custom rom on my gf galaxy s3 that has the built in hotspot hack. So I'm going to see if that one works. Id prefer to keep my phone because, well, I just think the optimus G is 10x the phone. But having internet is more important. The only other internet provider in my area is cable company that has a 10 meg line going to THEM! Meaning I get 0.9 meg downloads if im lucky with them.

Im going to continue to play with the treve mod, and try to get it working again, hopefully someone has an idea.

I tried setting up access control thinking perhaps if I limit it to just the two pcs it would help ( i have a tablet, and my home theater setup all connect) i couldnt connect at all when i did this.
[Sprint LG Optimus G] criddopher:
You know, I just thought about it. You said you have the same settings and version. This makes me think that perhaps

A; sprint has caught on to my usage and is locking it down on me? (but so far the galaxy tether has no issues, different phone on same account)

B; Is it possible some other device I have in my house is messing up the optimus g's signal?
[Sprint LG Optimus G] criddopher:
I still can't get this working, I also tried the galaxy s3 with its native hotspot enabled and same thing, after about 10 minutes i can't access new pages, but i can watch netflix all night long.

this has to be sprint cutting my connection off right? They can tell im not accessing mobile sites or what?

anyone have an idea?
[Sprint LG Optimus G] devo3d:
I GOT THIS OFF ANOTHER SITE BECAUSE I HAD PROBLEMS TOO....

Download Wifi Tether TrevE Mod APK

Step 2. Open the Wifi Tether app, hit Menu button and hit “Settings”

Step 3. Press on “Change Device-Profile”.

Step 4. Choose “Generic ICS/JB (wlan0)”.

Step 5. Choose “Change Setup-Method”.

Step 6. Choose “Netd-Ndc (master)”.

Step 7. Choose “Send Netd Max Client Cmd”.

Step 8. You can set your wifi encryption and SSID here to whatever you’d like.

Step 9. Make sure either “WiFi-driver reload” or “WiFi-driver reload 2″ is checked on. If wifi tether fails for some reason you can change this to the one you didn’t use.

Step 10. Scroll down and make sure “MSS clamping” and “Routing fix” are both checked on.

Step 11. Turn on tethering by hitting the Wifi icon.

Step 12. You can check logs by hitting Menu button->Show Log. If you don’t see any errors you are good to go.

Step 13. Now, try connecting to your wifi tether using your computer or another wifi device. Once connected, it should show up under Access Control. (hit Menu then Access Control)

Step 14. Enjoy your wifi tether without paying carriers twice!

ENJOY!

:D
[Sprint LG Optimus G] criddopher:
It doesn't work.(for long) Im pretty sure either sprint has caught on to my usage or my local tower is acting weird, I noticed that my connection drops here and there when i browse on the phone even. Im thinking thats whats causing the tether to drop. It just happens more often with the tether than on the phone.

Its just so weird that only new connections stop, open connections will stay connected.

I ended up getting my local cable company back, they upgraded to a whopping 3.9 meg.. beats the hell out of the .9meg it was

[One (M7) Q&A, Help & Troubleshooting] novsun88:
I'm trying to go back to stock ROM to do the OTA update. I have a bootloader that says the following ***TAMPERED***, ***UNLOCKED***, HBOOT- 1.44.000, RADIO04A.17.3250.20. Firmware is 1.27.531.11. I know that it also says S-ON even though I was S-OFF Before. I tried using moonshine to S-Off since I'm on 1.44 hboot. It did its process but still shows S-ON. Anytime I try to flash a firmware package it tells me FAILED (remote: 99 unknown fail). So I'm stuck. When I try to do a software update it will allow me to download, but I'm afraid to install as it may brick the phone. Any help?

Thanks

[Galaxy Tab 3 Accessories] Dabylpmis:
Hey Guys, just like to share my experience with buying a nice flipcover which meets my needs. First I bought the original Samsung Flipcover. It looked really cool and flat, but there were no magnets built in. So the cover just opend up when turned over. Also both of the flip-stand functions were very unstable. They were hard to etablish and you can't really use the touchscreen because the whole construction just collapsed when I touched the Screen. So the value for money ratio was plain unworthy of discussion.

So I ended up buying the IVSO Cover: amazon.de/gp/product/B00CWPILDE/ref=noref?ie=UTF8&psc=1&s=computers

I chose it because of the good reviews and the mention of magnets. The first shipment got lost, but after a short email contact with the vendor I recieved the second within 2 days.

The first impression is very good. It's a very good quality and the color was as expected. I chose the blue one, because it is the only one with white backcover. Any other color seems to have a black backcover, but I don't know this for sure. The Flipcover needs some bending in the first place because it is kinda stiff out of the box and the stand-functions needs a flexible flipcover. But after some usage the stand function works really fine. There is a magnet for closing the cover and one for the stand-function. Once put in the stand it is very stable. I even use the high angular stand in bed and still can use the touchscreen and it does not collapse.

[Xperia Z1 Q&A, Help & Troubleshooting] Mempha:
Hi,

I got the Z1 and love the phone(some bad reception on it, but meh ), however I've gotten a few problems.

Firstly, I bought a wallet casing for it, but it doesnt fit into the docking with this on ( and the big 'frame' placed in ), so I have to take this case off all the time.

The second problem was that when I bought display films instead, I bought the Copter fullbody ( front and back ), with theese on the phone got too thick to fit into the non-casing dock and way to thin to fit into the casing one.

This is really annoying, so does anyone have an alternative?

Like an docking station that has customizeable width on it ?
[Xperia Z1 Q&A, Help & Troubleshooting] papped:
One simple option is to just get the magnetic charge cable by itself.
[Xperia Z1 Q&A, Help & Troubleshooting] Mempha:
Yes,

I saw this as an option previously but I heard alot of people had problems with it not sticking. But am looking at options for this yes:)

Thanks.
[Xperia Z1 Q&A, Help & Troubleshooting] papped:
It works, it just isn't a very strong magnetic connection that holds the cable in place.

Hi all-

I'm returning to android after a three year relationship with Apple so I'm a little rusty when it comes to android. Anywho, I just got a GS4 for Verizon which is running MI1. I found the root for this build, and now want to flash the Hyperdrive ROM. I searched the Hyperdrive thread and noticed that it was compatible with ME7 and MDK. I was wondering if it was possible to flash Hyperdrive with MI1 or if there were any special steps.

Thanks in advance!
[Verizon Samsung Galaxy S 4] Crawshayi:
From what I understand at this time roms running with Safestrap are not fully functional if you are on MI1. I think WiFi is broken, not sure about anything else.
[Verizon Samsung Galaxy S 4] Cosmo1012:
Awesome! Thanks for the time being I can just root and run titanium backup to freeze the bloat apps until tjhe devs find a way around safestrap?
[Verizon Samsung Galaxy S 4] Crawshayi:
Well I think the rom authors just need to update the radio, Safestrap still works fine as far as I've heard. Until the roms get updated though you can root and freeze, but also install Xposed Framework and try a bunch of modules for it.
[Verizon Samsung Galaxy S 4] riker147:
WiFi has been fixed with this : http://xdaforums.com/showthread.php?t=2496027.

You also need to install Safestrap : http://xdaforums.com/showthread.php?t=2441441.

I'm currently running Hyperdrive on MI1 with Safestrap and the MI1 kernel module with zero issues.

Are you saying that your auto screen rotation actually works?
[Verizon Samsung Galaxy S 4] rpk213:
Auto-rotation definitely does NOT work with MI1

I've been running hyperdrive for the last few days with the MI1 also and autorotation is the one thing that doesn't work. Wifi is perfect though, so thats nice. I am very new to rooting and roms and basically all this, any advice on how to solve this? Should I just update and get out of MI1? This seems to be the ugly ducking of firmware...
[Verizon Samsung Galaxy S 4] SnydersWeb:
Problem is if you go up any higher you're even more stuck in locky-town where the only thing you'll have is Root.

I too am eagerly waiting for Hyperdrive over MI1 to support rotation. It has been the one thing from keeping me using it as my daily driver. For now I've been just keeping it on a ROM slot and booting Stock.

Wondering what can be done to help SBreen fix that.
[Verizon Samsung Galaxy S 4] rpk213:
Well ****...

So yeah, that's definitely not the news i wanted to hear. For now I am trying to find a way to manually toggle landscape mode in certain apps through the quick settings drop down menu. I really wouldn't mind that, but I just can't seem to find anything that manually does that. Every third party app or rotation toggle simply toggles the auto rotation that doesn't work to begin with. Starting to drive me insane. I'm just venting.

Do you have any idea if official MI1 support is in the works? Or should I just scrap my dreams of ever auto-rotating my phone in hyperdrive basically again?

Also where do you check for updates related to build number compatibility. Not sure where to check for these things. Random xda forum posts seem to have the best info, but its pretty unreliable when it comes to trying to find these threads.
[Verizon Samsung Galaxy S 4] joshm.1219:
Hyperdrive has nothing to do with the rotation issue, nor does any ROM. It is kernel dependent. Unfortunately, Safestrap needs KEXEC support to be able to get that low in code & touch the kernel.

While Hashcode, the inventor of Safestrap, is working on KEXEC, it's been months so realistically I wouldn't be too optimistic about it.

If you want an S4 with custom software, switch carriers or buy an MDK device, that's what I did.
[Verizon Samsung Galaxy S 4] SnydersWeb:
Actually on further info I got after making this response, the problem is NOT on Hyperdrive, it is on SafeStrap and getting KEXEC to work. Once Hashcode is able to crack that nut, then we'll be in luck. until then it's an exercise in patience.

Hello, just about to pull the trigger on a new xperia ZU, but i wanted to see if anyone had any tricks for me to try on my Xperia Z. I was running near the latest CM 10.2 without issues for awhile now. Last night while i was bowling the battery died( nothing new happens all the time to me :) ). When i returned home i hooked it up to the wall charger for about 30 minutes, came back and still no life. I have tried multiple chargers and multiple cables with no luck. Device has been plugged into power all night and all day so far. When i attempt to power on with it unplugged i get the 3 pulse red led. When i hit the power button with it plugged in all i get is a solid red LED. Nothing more, nothing less. Cant get into recovery or anything. Most of the time a hard brick involves a mis flash or something along those lines....any idea what could have happened to mine?
[Xperia Z Q&A, Help & Troubleshooting] ronald_loulan:
It might be the battery...

Its not advisable to full discharge the battery but it seems that u did it a few times..

The battery might not take any charge as the red indicator means low battery...

Tried a new battery,i know after removing the rear panel n say good bye to water resistance but is worth a try...

Or u can send it to me for free if u wanted to throw it away... :D

hope this helps...
