[Q] Variety of issues (unlocking bootloader, randomly rebooting phone, etc) [Resolved - Nexus S Q&A, Help & Troubleshooting

Hi! I realise this if my first post I'd like to tread lightly; but I'm about 4 days into solving my issues and I just want to finish it...
I've had my Nexus i9020a (bought from Koodo) since ~May 2012. I upgraded to ICS sometime in the summer and sometime in the last few weeks it has started rebooting. I hadn't been installing new apps, etc. I'm not sure what the cause is. I 'Factory Reset' today in an attempt to resolve the issue, thinking it may be a program gone AWOL; but it has rebooted a few times since. I *just* looked through rebooting FAQ on this site and have edited the first few features listed there. I'm not sure if it has worked yet, but I'll get back to you on that. For the record, the only programs I have installed now are Swiftkey 3, Handcent and Beats (DDR simulator, updated in November).
In the meantime, before I found the solutions here, I decided to take another shot at unlocking the bootloader and try installing... probably CyanogenMod.
Specs: Windows 7 64 bit with Nexus S I9020a (Koodo) running 4.0.4 (4.1.1/2 OTA haven't come through, despite dozens of attempts at clearing the GSF cache, etc)
So I've been using the Nexus S: Full Update Guide found at:
hxxp://wiki.cyanogenmod.org/wiki/Nexus_S:_Full_Update_Guide
(It won't let me post the link)
I've followed the guide for installing the Android SDK, gone to CMD and typed 'adb devices' and had it show up. Theoretically, the SDK should be running fine.
Next, I turned on the USB debug mode. Then I booted up the bootloader, plugged the NS into the PC... and despite not having issue when the it's turned on (driver installed properly) windows says drivers have not been found for the device. Thus, when I type fastboot devices, it comes up with nothing.
I've been, and will continue perusing forums for this, but so far I haven't seen anyone with this specific problem.
Edit: I have also gone to the directory with fastboot/adb and used cmd to reboot into the bootloader, only to have windows 'ding ding ding' an unrecognised device.
2nd Edit.
I've gotten a stage further! I'll keep the thread open because I may come across something and it's nice to write my issues down. Seems my head can wrap around the problem a bit better. Anyway, I installed PDAnet and BAM, it works. Onto getting CWM installed! Thanks for the, uh, help!
3rd Edit.
CyanogenMod 10.0 stable is booting for the first time!! It's taking a while... but I appear to be on the home stretch! Also, my phone didn't reboot for a few hours before I installed CM. So if I don't end up somehow bricking it... and I mean, this first boot is taking a heck of a long time... The animation sets me at least a bit at ease... maybe 4.0.4 will work out...
Edit 4
I forgot to clear the app and cache data before flashing the ROM to the phone and thus the issue... after a VERY tension filled moment of pulling the battery during first boot... I rebooted, cleared said data and reflashed the ROM. After a boot, I realised I forgot the GAPPS zip and fixed that. Now I'm running CM10 Stable!! I'm stoked that after months of putting it off cuz last time I did it I didn't get anywhere after many days, but now it's done!! Thanks again for such an awesome site!

Thanks for sharing your experience instead of just saying "Mods please delete this i solved my own problem" :good:

LG MyTouch E739 Boot Issue

First thing...greetings! Yes, I am a n00b (loved the video, though) and have searched for quite a while to hopefully resolve the issue I am currently burdened with. A thousand pardons if there is already another thread like mine, but I just couldn't find anyone with the same issues I am having.
First off, I started with rooting my phone. No problems.
Got my hands on ClockworkMod's ROM Manager. Downloaded Cyanogenmod 9 to my PC, and any other necessary programs to get this flashing underway. Opened up ROM Manager and proceeded to boot in recovery. This is where I think the problem originated. I wiped all that I needed (or so I think). It's entirely possible that I may have missed something. Not sure. After wiping it clean, I then went on to install the zip of cyanogenmod. All went well. Then the reboot. It starts up and gets to the loading screen with the really cool animation. 5 minutes. 10 minutes. It's constantly loading. I head on to google and search some possible culprits and solutions. There were suggestions to go back into recovery mode, but the thing is, when I try to get to that menu, it doesn't seem to pop up and goes right back to attempting to boot.
So, all things said...is there any possible solution? Any help would be greatly appreciated. And again, if there were any threads with my specific issue, many many apologies!
Thanks again!

[Q] Question concerning Dragonzkiller's Droid x2 CM9 Rom

Alright, so here goes. I've searched the thread for the issue I'm having, but have come up empty handed. I'm not Droid noob, especially not when it comes to flashing roms. But, here are the details I have.
I had been following dragonzkiller's development on his ICS rom. I hadn't really put forth any effort looking lately until yesterday, and saw that he had the wifi and camera fixed, which were really my two biggest issues, so when I saw that, I was excited. I began working on getting it all running. I've had the x2 for about 5 months or so, and usually, the first thing I do, as soon as I get a new phone, is root it. Back in April, I rooted with GingerBreak. Worked good, no issues there. Back in June, apparently I still received the OTA update taking it to 2.3.5-418, which I found out last night had kinda broken my root. So, I went back to find a way to re-root. I did that, with a desktop .exe that went in, and was supposed to flash BSR to my phone also. After I ran that, all my root permissions started asking for options again, so I was relieved. Now, for the issues I'm having.
I downloaded an app in the play store called Online Nandroid Backup. For some reason, and I think this may be a dev issue with the app, it won't run a backup, and tells me that it wasn't able to be granted superuser permissions, even though it is prompting and I'm allowing. Issue number two is this. I've tried 3 different ways to get this working. I used ROM Toolbox Lite, selected the rom I wanted to flash, and wipe data and cache, no delvik. I've selected to run a backup of my current rom. When it boots into recovery, I only have 4 options. Reboot your phone, something about installing the rom from sdcard, wipe data, and wipe cache. I'm not given the backup option on the recovery. Furthermore, when I kinda just decided that since I hadn't had any trouble flashing a rom to any of my other phones I've had, I would just try to flash the rom, it gives me a prompt about 25% through the rom package saying E: signature could not be verified, or something to that extent.
Even though it has said not to use Rom Manager, I did download that and try that, and got pretty much the same outcome of no rom, just a bit different scenario going through. Rom Manager won't reboot into recovery, and when I select to do a backup, it reboots the phone straight up. I also used the manual entrance into recovery, volume up, but it tells me something about starting RSD protocol, and sticks at that forever.
My real questions are this... I've always ever used CWM. All of my previous phones have been supported by Rom Manager nicely, so when it came to downloading and flashing a rom on them, no problems at all. I have never used BSR, to my knowledge, so I'm not sure if the recovery screen I'm seeing is the actual BSR recovery, or if it's some other recovery. If it's not BSR, do I just flash it like I would a rom, then re-run into that? And does the signature issue that I'm running into mean that I have to wait for a signed version of the rom in order to work it? Is there any way to fix this issue, or am I basically SOL right this moment? Any information on how I can fix all of this would be greatly appreciated. Thank you.

[Q] Issues with A701 upgrade to 4.1.1

Hi All,
Really sorry to post a new thread about this, but I am unable to add a post here: http://forum.xda-developers.com/showthread.php?t=1911437
So, followed Member - OPs guide to manually update my A701 to JB.
Simply put, the patch would not install (failed with a permissions error)
Put JB on anyway (just to see) and this won't let me get past the choice of language and location (Also, at this stage, SuperUser tells me system is requesting SuperUser access and whatever I do, it accepts)
So, used CWM to put the 4.0.4 build back, and that worked fine - though according to About Tablet I am actually on 4.1.1
I see improved UI speed and responsiveness, it's all looking great.
But Play Store won't run. Tried adding the latest version, still 'unfortunately stops' Also Nova refuses to run.
Has anyone run into any of these issues (Patch not installing, Play Store failing) and have any ideas what I can do to fix them?
Really sorry again for making a new thread in the wrong forum, I didn't see a choice (other than waiting!)
Thanks in advance,

Mate, it doesn't sound good.
What I would do, at this point, is Fastboot the 4.1 image again.. And stay the heck out of CWM. If you Fastbooted the 4.0.4 image, and you still have it showing 4.1, then you have a serious issue. So boot to fastboot, and try it again. Clearly, whatever you did with CWM, didn't work,
Installing a rom from CWM, requires certain things to be done, either in the install script, or via CWM.
Most notably, Formatting User data, cache, dalvik, system, and data. If any of these do not get done, chances are, the rom install will not go good. The basic install script, generally only formats System and Flexrom. This is because Acer distributes a full rom with the understanding there is nothing on it. Most rom modders know this, which is why they give extra instructions via cwm.
The big thing, is when you boot your tablet, is if it says which bootloader you are on. So you have to look,. You want to be on the JB bootloader.
MD
Thanks for the response MD,
A tiny bit unsure how to proceed. I understand everything that you said (well, I think I understood correctly!)
I have in fact tried to fastboot the 4.1.1 image again, and again I am stuck on the language and location screen (did this last night before giving up for the day)
I have read and understood "Stay away from CWM" (and I know that it is in this case only - have used CWM on my Gnex without issue)
Please forgive me if what I am about to write is ridiculous - this is kind of where we'll see whether I understood correctly or not.
I'm thinking that if the various areas were not wiped, and that could be the reason for the snafu, then it would be worth going into CWM (which I have been warned to stay away from, and which I would stay away from except for this one thing) and formatting the user data, system, dalvik etc, then applying either the 4.1 or 4.0.4 to result in a working tablet.
Or possibly flashing the bootloader to make sure it is JB
Or going back to the weird 4.0.4/4.1.1 hybrid which works but doesn't allow Play Store and finding a way around that issue.
Mate, I'm not sure which way to go at this point!
Fastbooting 4.1 is a dead end at the moment (but could that be a bootloader issue....)
Fastbooting 4.0.4 gives me the hybrid (though I can check this again tonight)
BTW, the only CWM Rom work I have tried to do has been with the patched update (second downloadable file I think) - everything else has been done via ADB
So.....CWM to wipe/format caches? (I'm thinking 'NO! DID YOU NOT HEAR WHAT I SAID ABOUT STAYING AWAY FROM CWM????' but I'm asking anyway!)
Flash a new bootloader on? If so, any idea where I would find it (will obviously search here and Google)
Thanks anyway, and thanks in advance if you have any more advice. I really do appreciate the support!
Al
Well Al,
This is perplexing to say the least. Clearly fastbooting the 411 results in frozen at the wizard. My question, when you have the unlocked bootloader, does it say JBxxxxxxxx unlock mode when you boot the tab? Because it should. If it doesn't, then you're still on ICS bootloader. And will have to do the CWM thing to get JB installed. The 411 image flash, is to get a rooted version.
And this is the point. Personally, I do not trust the CWM's at this point. That's just me (already bricked 1 tab 3 months ago with a faulty CWM) I know the folks with ICS are using Pawitp's CWM, and haven't reported issues. But I don't know if they are doing wipes or not.
As with the 404 image, well, why playstore doesn't work is perplexing. You could try reinstalling the playstore via manual method (root required). Which is to delete the vending.apk, install a new vending.apk (making sure permissions are the same as the other files), then reboot. Go to settings, wipe the playstore cache's. Then try Playstore again. This was an old method we used with market issues in HC.
Personally, I feel the issue is with the wipes before running the patch. But I would hate you do the wipes and formats, then discover the emmc chip bricked. So it's 50/50.
But heck, you have warranty. Just install some update.zip, and it resets your bootloader so service doesn't complain
Wish I could give you a definitive answer, but these processes are too new.

Hi MD,
Thanks for such a speedy and useful response!
Warranty: nope! I'm in China, bought the tablet in Shanghai (now way down south in Shenzhen) and it was a dodgy deal to say the least. I suspect they were being lifted from the factory. No complaints from me about this, or about any difficulties caused by rooting/flashing/CWM. My choice of action all the way along and I am aware of the risks
Just flashed 404 again and it is fine so far, again very nice and smooth. Going to look at the Play Store and see how it behaves, see what I can do as far as vending.apk is concerned (although I'm lost when it comes to permissions. Obviously I know what permissions are in tech terms, but no idea where they would be set, how to change them, what to use as a reference) I figure this is the path of least resistance for right now.
Then I'm going to see if I can apply the standard A701 update to JB (which I won't be able to because of rooting/unlocking but I will fiddle around) and see if I have any joy.
Got my keen eyed gf to check the message on boot, you were right that with the 411 image applied it still had an ICS bootloader, so that's good to know if I want to try going back to the flashed JB image. However, I have no idea how to flash the JB bootloader/kernel, and the CWM process for the patched update fails each time (despite editing the first line of the necessary file in META-INF/Google/Android)
So, I will keep you up to date with progress. Fingers crossed!!!

Quick update.
Play Store seemed fine for quite a long time (although I didn't download anything, I was able to browse no problem)
Went to install my back up of Nova, and of course had to tick 'Unknown Sources'
As soon as I did that, allowing installation of apps not downloaded from the play store, I got the 'Unfortunately Play Store has stopped working' message. Before I installed anything else, immediately I ticked that box.
Unticked it, but still not working - installed Nova, not working.
So....

Well, seems like Nova is the culprit. I assume you are talking about nova launcher? Or nova the game?
Hi MD
Yes, Nova launcher but no, it's not the culprit. At least I don't think so.
The play store stopped as soon as I ticked 'Install from unknown sources', before I installed Nova.
Very odd.
Quick questions:
1) Any advice/links/downloads for changing to JB bootloader if I apply the 4.1.1 again? Given that I cannot run the patched update/flash from CWM, I am guessing I would need to directly install/flash the bootloader from ADB...
2) Don't kill me for asking this. I know to stay away from CWM, I have seen you post it a good few times here, I heed the warning....BUT.....
Given that I have CWM installed and it's working ok (apart from failing to apply updates) - I have 6.0.1.4 - many of the guides to updating the 701 say it needs 6.0.1.1. Would the slightly more recent version of CWM make a difference in terms of success or failure of the update? Update is failing with a 'set_perm:some changes failed' very early in the update.
Seriously, I am being extremely wary of CWM, it's just that currently I have a slightly disabled tablet and it would be great to get this sorted.
Thanks, once again, for all your help,
Al
Update again, put 404 back on (after issue with play store and unknown sources)
Opened play store, downloaded Apex launcher - all good.
Ran Apex, all good....then suddenly Play Store stops, Apex stops, never to return.
With 404 img on, About Tablet still says 4.1.1
The saga continues!!
Aaaand that's the end of that!
Put 4.1.1 back on, pushed the boot.img from the official update.
Now no CWM, so it seems no recovery mode....if I try to get there by volume down and power on, it goes into update mode.
And of course neither the official update nor the 'patched' one will apply.
Can boot to the first start screen (language/location) but can't get any further.
Maybe I can find a service center here in Shenzhen who can sort it out.....as I said before, no harm no foul, I knew the risks!
Thanks one more time MD for all your support and advice )
Or is it......?
Didn't give up, didn't surrender. Found out how to get into fastboot using frantic waggling of the rotation lock.
Just flashed 404 on again, waiting for boot to finish. Might still have a semi-usable tablet! Then I just wait till a 100% working JB manual update surfaces!

HA HA, you found the User Data wipe.... Yeah, a little known secret from the 500 forums.
MD
It's so strange....so now I'm back to having flashed 404 but the tablet thinks it's 411.
Play store was fine for about 40 minutes, I quickly got chrome, currents and BBC news.
I turned off the Acer ring and play store died...
But here I am, typing to you on the tablet and it's fine. And what a change in performance. It's most noticeable in currents..the increase in speed and smoothness when scrolling between pages makes it at least ten times better than before.
But the last flash was 404....weird....
I'll leave it like this for now. No market but at least it's not semi bricked!
Super Quick update - in lieu of finding a sparkly copy of vending.apk, I tried wiping data and uninstalling Play Store (reverting to factory)
It duly downloaded a new version, and worked fine.
Then I popped Apex on, the GPS got busy, and Apex and Play Store died.
The wipe/uninstall worked again for Play Store so to be honest, I am currently quite happy. Ok, it's not perfect, but if I can quickly reinstate Play any time it fouls up, I can still build up a decent amount of apps to make the thing useful.
And seriously, whatever changes are there (considering the weird 404/411 hybrid) the performance is incredibly enhanced. All the faffing has been worth it, it is finally the tablet that it should have been from the start.

Well, good news then. I think it's an interesting set-up. Hybrid. Still not sure though, why it pulls 411 from the build.prop as it should have been changed when you flashed the 404image. But honestly, after reading the OP's steps, I believe he references going back to 404 via CWM, and not fastboot. This of course would mean installing a full 404 original rom. I'll have to look over my JB system dump and see where the other prop would be. Maybe something changed in JB.
So if you can live with it, it's probably better to leave it be till we come up with something more definitive.
MD
"So if you can live with it, it's probably better to leave it be till we come up with something more definitive"
Yeah, totally agree.
Mate, seriously, thanks for the support and advice on this. It makes a big difference. Even as I sat there last night with what seemed to be an unusable tablet, being able to chat to you about it meant that at least I didn't feel completely adrift!
Big big thanks

Stuck at system loading.

Hello.
First off i will start with the fact that i've read most of topics proposed by Google and Xda forum search, so please don't treat me like an idiot.
From what I've noticed there's quite a few people with similar problem - after going back to stock ICS everything was fine for a week then boom, this morning i wake up and my TF101 is refusing to turn on. First off I've thought its just a fail and i will fix it easily but now I'm seriously scared. So far I've wiped device around 10 times, and so did i tried to install other system software (I've had couple zip files with other rooms stored on my SD, and Clockwork recovery works fine except for the fact that when i use "Super wipe" from android revolver it's getting stuck on clearing DATA).
Some detailed info :
After installing energy ICS device does not even go to loading screen, just keeps on boot loop.
After installing CM10 there's no boot animation change...
After installing any ROM and rebooting there's this installation bar... it progresses instantly.
Did anybody had similar problem which they got fixed by some magic method... or should i just throw my transformer into the bin? I'm clueless now, hope you can help me out.
Regards Nekyo.
Edit : 2h later , Fixed it through the NVFlash... thanks for all support.

You wait 2 hours and then complain there was no support?
If you run into a problem you can't fix on your own, you're not going to make many friends expecting people to jump on your issue within 2 hours.
This is XDA, basically a DIY forum, if you want support here, expect a few days delay for an answer that helps.

[Completed] Nexus 7 (2013) Cyanogenmod stuck at loading, cannot connect to computer

Ok first, I did a lot of research into the topic and spent more than a few months in thinking it over and seeing if I wanted to attempt this. In a day long research fest, I finally decided to just try rooting and installing my daily-driver Nexus 7 2013 Wi-Fi with CyanogenMod. I chose a method that wasn't too daunting, using the Nexus Root Tools to push the CM rom and finally into working... I used RootJunkie on YouTube, "How to Flash a rom with the Nexus Root Tool Kit plus make a Backup with one click" as a refrence, watchign and rewatching the video and all he referenced over and over.
I loaded the zips into the "Flash Zips" section (It loaded the GApps zip in first and then the CM image). It seemed to install without a hitch except the GApps weren't there. Figuring that it installed the GApps first and then wiped them, I redid the flash with the CM first and the GApps second. Now I'm stuck in the Cyanogenmod loading screen. Problem is, since it's hit the point where it installed everything and hasn't let me into the device, I haven't been able to enable USB debugging. Now the computer isn't able to recognize the device at all and I cannot push just the CM image to fix it nor can I restore factory since the computer doesn't recognize it.
I've attempted to boot into recovery mode, which just results in the android laying on its back with a red ! in a triangle over it. I'm sorry if this makes no sense but I'm slightly panicked because I can't afford to have this thing professionally fixed nor replace it at the moment and I use this tablet daily. Is there something I'm missing? I'm going to lay down for now and try to calm myself, letting the thing sit at the loading screen, hoping that it'll let me in after a while. What options do I have, I'm sorry if this is the wrong place, the wrong crowd... I've just browsed quietly and used XDA as my source for information for everything from rootig my first device to this and it seems I've overstepped my abilities in this.
Problem solved
I stepped away from my computer and tablet for an hour or two to calm down from a panic I was in and found that it let me into the bootloader finally where I flashed the stock image and then restarted the process.
I discovered my problem in trying to use the 'stock' level of GApps from opengapps when the Cyanogenmod wiki pointed directly for the 'nano' version. Sorting out a silly wizard crash later and my tablet is happy, healthy and working much better than the stock at the moment aside some setup I need to do.
Thread closed as OP solved his issue
