[Q] Nexus 7 restore to factory - Android Q&A, Help & Troubleshooting

Hi - My sister has asked me to take a look at her Nexus 7 as she wants to upgrade it to the latest Android version. Unfortunately she bought it second hand and it had been rooted. It also seems to have the clockworkmod boot loader.
I'm having issues just trying to get this thing un-rooted and back to factory as it will not install the Android 5 update. I have used the Nexus Root Toolkit and all goes well right up to the part where it puts the device into recovery mode - my PC loses its connection to the Nexus and then the connection attempt times out. I have downloaded the Android 5 zip from from google and put it on the phone, then booted into recovery mode and tried to install from the zip. I just get an unhelpful 'Installation aborted' message. just not sure as to where to go from here..,.

The download from Google isn't meant to be flashed in recovery... it's the factory image files zipped. You have to unzip it, then unzip the zip that's inside also, then you should be able to fastboot flash the bootloader, recovery, system, data, and userdata.

[Q] CWM Touch won't "stick" Galaxy Nexus Verizon

I have been trying to get my rooted Galaxy Nexus to load the CWM Touch recovery image, and I just can't seem to get it to stick. I originally just tried to install the basic non-touch version from Rom Manager. When it rebooted, I got the red ! and a dead robot. So I booted into fast boot, and flashed the touch recovery. After flashing if I go straight to recovery, I do get the CWM recovery and can backup. My problem is that if I the reboot the phone, I can never get back to it again. I always end up at the red ! and a dead robot.
I read on another thread to rename the file "/recovery-from-boot.p" to "recovery-from-boot.p-bak" and that it might require reflashing the image. I moved this file and re-named it, reflashed, booted into android. Then powered off and booted into recover mode, just to see the red ! again.
It seems that when I first flash I can go into it, but anytime after that it just dies. Anyone have a deeper knowledge of what is going on here and care to point me in the right direction? I could probably just go ahead and flash a new image to the phone but I don't feel good doing that while the recovery image seems to need re-imaging every time.
Hi there,
You're correct, you need to rename/delete that file to make cwm stick on the nexus.
If you reboot the phone before removing that file, the file will update your settings to point to the old recovery instead of cwm.
Since you've just renamed it, reinstalling cwm should do the trick.
You're renaming the wrong file. You need to rename or delete install-recovery.sh from system/ect

[Q] How do I unbrick my T-mobile Springboard?

Okay, so this is what happened:
1) I received the OTA update and everything went fine with upgrading the my T-mobile Springboard tab to ICS 4.0.3
2) I then got brave and went ahead with rooting and installing SU using the technique described in "Root Stock T-Mobile Springboard" by xdajunkman. That worked fine and I was able to get CWM recovery installed.
3) I then tried to install the [ROM][ICS] [Unofficial] Root-ready Huawei/Springboard International ROM and downloaded the dload folder to my SDCard, etc. I tried using the dload folder with the ulmt.cfg file in it and that failed with a "Installation aborted" message. I then removed that file and tried to go into CWM and tried "Install from zip" approach. Same thing...installation aborted message.
4) So, then I did the next stupid thing...in CWM, I formatted my /system, /data, and /cache. That was a big mistake! I now have officially bricked by tab.
5) I tried to get rid of CWM recovery by extracting the recovery.img file from the stock rom zip file. I fastboot flashed that to the recovery and recovery2 partitions. I then thought, let me try extracting the update.zip from the stock rom zip and put that on the root of my sdcard and tried to install that. No go...it just says, update failed with a big red "FAIL" message in the center.
6) I then tried to install CM10, to see if that would work. I downloaded the TWRP recovery and also the CM10 ROM .zip file, along with the google apps zip. I flashed the TWRP recovery using fastboot. That worked fine. I was also able to install the CM10 Rom, or at least it reported back "Successful". Same with the google apps zip. But then when I reboot, it only gets to the T-mobile Splash screen and stays there forever.
Please help! I tried to install the Stock Rom using the TWRP recovery, but again, it reports "Installation aborted." So, what am I doing wrong or what can I do to fix this?
Thanks.
[UPDATE] -
Okay, so I actually tried installing CM10 again using the TWRP recovery since it said that it was "Successful." And sure enough, it was successful, it seems. Once I installed it, rebooted the tablet and waited on the T-mobile Springboard screen for about 10 minutes, it launched CyanogenMod. I then set up the tablet with CM10. I had received the unlock code from T-mobile and so my tablet was sim unlocked. I put a AT&T sim card and sure enough it got signal and I was able to surf the web and make phone calls. I downloaded the speed test app from the Play Store and noticed that I was getting about 1.5Mbps download and about 600kbps upload. Not bad. The problem I noticed is that I can't receive calls. I can call out, but when someone tries to call me, the tablet doesn't acknowledge an incoming call. The caller just goes straight to voicemail. I do get a voicemail alert.
So, I don't know whether that is an issue with the CM10 build or a problem in my network / APN settings.
I would like to get the rooted T-mobile International stock ROM on there so that I can try it with that. I'll keep you all posted.
Thanks!
9 times out of 10, I get installation aborted errors because of a botched download. Try downloading the file again, and if available, verify that the MD5 sum of your downloaded file matches the one provided by the developer.
And if I'm not mistaken, TWRP recovery and CWM recovery aren't capable of flashing the T-Mobile stock recovery. If you have TWRP working properly, I would continue trying to flash one of the unlocked ROMs available. I highly recommend HWMOD's ICS (available here)
Best bet would be to fastboot flash the recovery img from the hauwei site update.zip. Then do the standard pop the stock hauwei update.zip on the sd card and do the normal upgrade method. That should full wipe the phone and then you can start tinkering with it again. Also huawei posted the offical root on their site.

I don't want to mix up the T-mobile images with the Huawei images. Even though I've screwed things up already. But, if you read my previous post, I've got CM10 working, but no incoming calls.

[Q] Stuck at boot logo after root

Hello.
I have a GT-i9305 andI tried the rooting by following the instructions at http://galaxys3root.com/ on my Ubuntu laptop with heimdall.
I managed to install the recovery and also flash the cwm zip. I saw som problems related to /cache/ so I wiped cache and after that I have not been able to get past boot logo. I hav ealso tried flashing a custom rom and doing a factory reset and wipe dalvik cache bu
t it did not help. I have tried Odin and flashing from a .tar.md5 file but it results in FAIL.
I can reach both download mode and recovery but that is all.
Please help, I need my phone.
did you use a i9300 method on your i9305? you've probably killed the phone.
flash a stock ROM via Odin (i9305 one) and factory reset from recovery. if that doesn't help - send it to Samsung.
And this is the i9300 section, you're in the wrong place
Thanks.
I got back to stock. I will try to use the i9305 method.
Mount /sdcard not possible
Wel, I have the same problem.
Samsung SIII International version. After installing a new rom (believe it was "jellybam-v6.1.0_i9300-STABLE.zip") but I am not sure, the phone boots only to the original logo and then the screen goes black. Nothing more.
I can get into recovery mode and download mode so I tried several recovery versions (CWM, TEAMWIN, latest ClockworModRecovery v 6.0.2.8.) and several ROM.
No mater what I install, I get the same results. Boot phone and it hangs after the standard Samsung logo.
I was able to find out "/sdcard" could not be mounted. All the recovery programs I used with the option "mount unmount" reporting the same "/sdcard could not be mount" error.
Formatting /sdcard all so won't work.
I am thinking installing a new kernel but I have some difficulties in finding witch one will work with my phone?
Any suggestions or help is really appreciated b/c I have no idea what to do next.
Samsung I9300
Win 7
Latest USB drivers from Samsung installed
No Kies installed.
Odin3_v3.07 installed.
Using Odin I flashed:
CF-Root-SGS3-v6.4.tar
recovery-cwmtouch-6.0.2.8-GTI9300.tar
recovery-stock-dlj4-GTI9300.tar
recovery-stock-blg9-GTI9300.tar
And a few more.
Due to being unable to acces the phone installing a zip file is not possible. Using "installing a rom from zip, or sdcard" from recovery is not possible.
I tried installing a file using sideload but was not succesfull. I can get the phone in receiving a file from sideload but was unable to send a file from the PC.
Thanx in advance
you have to do a factory reset after flashing a new rom
Did wipe/clear/factory set etc every time just to find the phone goes black after the Samsung logo.
One particular thing: I can see the /sdcard in some recovery programs but can't modify it.
How can I transfer a zip file using Sideload?
I can get into "download a file using Sideload" on my phone but what should I do to get a zip file transferred. Maybe then I can use "install from zip" from a recovery.
Update Problem solved (for me) http://forum.xda-developers.com/showthread.php?t=2162908
I flashed the 9305 firmware from here http://www.samfirmware.com/ in Odin then I was back to stock.
Then I rooted the phone by this instruction.

I have not tried a custom rom but I think it should work.

Can't install ClockWorkMode on my Galaxy s3

Hello,
I come for you, because I am trying to install android 4.4 on my phone, because android 4.3 isn't compatible with pokemongo.
I have a galaxy s3 GT-I9300 from a few years, I've never rooted it and it runs on android 4.3.
I've been looking for guides that say that I need to install CWM recovery to then be able to install CyanogenMod.
So I've downloaded Odin, and CWM recovery, added the CWM recovery .tar in the AP box of Odin, put my phone on download mod, plugged it, and run Odin.
It appears that it works succesfully, but when I reboot my phone in recovery mode, I still have Android Recovery System <e3>, and I can't install zip from sdcards (if I understood correctly, <e3> doesn't support zip, whereas <e2> does, and CWM is supposed to put it to <e2>), so I can't install CyanogenMod.
Here is a screenshot of my Odin after running it: (I can't post the link since I'm a new user, so it's on imgur)

I can't think of any more information to provide for now.
Thanks for your help.

It could be permission issues. But try using a different cable.
Also, the recovery you are flashing has to support the model of the phone, otherwise, Odin will refuse to install it.

Thanks for the answer, I was not in root mode.
I fixed it and it now works, I have been able to install CyanogenMod from the zip in recovery.
Now I tried restarting my phone, and it's stuck in "Android is starting".
I have a little blue alien popping on my screen, then the screen turns off, then the screen turns on and says things like "starting applications, preparing settings, optimizing applications". But it seems to be doing it on repeat and it's been an hour. Is it normal that it takes so long? I haven't seen it mentionned anywhere from what I checked.

Help getting Ramos MOS1 Max to boot again

Hello, I need a little advice on getting my phone working again. I got a new Ramos MOS1 Max today and rooted it via Kingo PC software. I checked to make sure it was rooted using RootChecker and it said it was rooted. I was reading up on what to do next and some sites said the next thing you must do is to make a backup of your phone via TWRP. I installed the software and then attempted to use the "reboot and create backup" functionality. The phone rebooted and I was in the Android system recovery menu. I didn't see anything like what TWRP was supposed to show, so I just rebooted via the standard recovery screen method. Now when I try to start the phone, it gives me a logo, then ARMPHONE and it hangs on that.
I've tried wiping my cache partition via recovery menu and rebooting, but no dice. Next they suggested to do a wipe data/factory reset, and since I just received the phone today, I decided to try that. After doing that via system recovery menu it still wouldn't boot past the ARMPHONE screen. I don't have a lot of experience with rooting and modifying Android devices, is there something I can do to fix this? I've installed the android SDK tools for my version of android (5.1 I believe), but I don't know how to proceed. Is there a stock image I can use for this phone, or can I just use a vanilla android image?
Thanks in advance.
