Unable to get into Recovery after 4.1.2 upgrade... - Nexus 7 General

Ok, so I ran into a VERY weird issue and was wondering if anyone else has experienced this or has a better solution then what I found.
My Nexus7 was running stock JRO03D. I had it rooted, using the Motley kernel with CWM Recovery - but outside of that, everything else was pretty stock. Anyway, I decided to upgrade to the 4.1.2 image. I pulled the one it downloaded automatically out of /cache and looked at the updater-script to see what it did. I noticed it replaced a lot, including the boot image, so I figured it would be better just to let it do everything and revert my custom stuff later. So I replaced the kernel with the stock JRO03D kernel and, using CWM, flashed the upgrade. Everything seemed to go perfect and it completed the upgrade. Prior to rebooting it, I also flashed the "unofficial" motley 4.1.2 kernel posted on XDA. I rebooted the device, and CWM warned me that 'su' needed to be fixed (how nice!) and made it suid again. It rebooted and after android "updated", everything was up and running. I confirmed in settings that it was on 4.1.2 with the custom kernel. SU was suid root as well. Perfect!
Not quite.
I decided to try rebooting into recovery to make sure CWM was still there, or flash it back if it wasn't. I opened up a terminal emulator, removed the new recovery-recovery image in /system, and did "reboot recovery". The Nexus7 rebooted, but rebooted right back into normal operation. Very weird. So I hooked it up to my computer, figuring CWM was gone, and tried to fastboot flash it back. Fastboot said it did, but I still wasn't able to reboot into recovery. I tried three different versions of CWM and even TWRP, but no dice. Every time I tried rebooting into recovery (using terminal emulator, adb shell or bootloader method) it just went right back into the normal boot process.
I spoke to some people on IRC who recommended reflashing the stock image from Google (without wiping user data). I reflashed the bootloader and then did a fastboot update <stock image>, and it said it replaced boot, recovery, system, etc. It rebooted automatically, and I tried going into stock recovery. That still did NOT work. Instead, I got a very sick looking android guy who was lying down with a red triangle with an exclamation point over him. I was a bit worried and upset at this point. I tried reflashing CWM/TWRP again, but nothing. When I did this, I no longer got the unhappy android image, but it just booted up normally.
I decided to try and doing a more thorough wipe, using fastboot to wipe cache/boot/recovery/system manually. Then I reflashed the bootloader and stock image. Still no recovery (stock or custom).
As you can imagine, I was getting even more concerned now. Especially since I was no without root and no way to get it back (since I couldn't get into recovery to flash the zip for it).
I tried every other thing I could think of to flash recovery back, but nothing worked. It wouldn't load at all.
Finally, I was about to do a complete factory reset and wipe/reflash of everything, but one last thought crossed my mind. I found the older (JRO03D) bootloader and flashed that. Reloaded bootloader and selected "Recovery". Voila, I was in TWRP Recovery Mode! (which was the last one I tried installing). I was able to reinstall my SU.zip and get everything back up and running.
SO, long story short, I'm now on 4.1.2, running the newer unofficial motley kernel and have su back. But I'm also stuck on the older 3.34 bootloader. If I try upgrading it back to 3.41, I won't be able to get into recovery.
Has this happened to anyone else? It doesn't seem like it. Is there a HW issue with my device causing this problem? I can't believe it's software related since I tried two different copies of the 3.41 image. Does anyone have any other suggestions on how I can upgrade the bootloader while keeping the ability to get into recovery mode?
Also, while everything *seems* to be working OK using 3.34, do you think it will cause other problems since I'm using 4.1.2?
Thanks.

*MOD EDIT* please don't quote the entire OP
Thanks for the bootloader info. I was in the same boat, and once I found your post, I went back to JRO03D and my recovery has returned.
Again, thanks, you F'n rule!!!

That android with the red triangle sounds like the stock recovery... so I think you actually got it to work, but you just didn't have a custom recovery...
Then again I don't think I've ever seen the stock recovery. Haha

No problem. I'm glad to hear that my solution above helped someone else, and also that I'm not the only one experiencing the problem. I assume you mean you only went back to the JRO03D bootloader and not the whole image, right?
What I'm most concerned about is that it seems like my N7 (and possibly yours as well) is defective. I'm not an uber-expert on Android, but I'm fairly knowledgeable. With a stock system, outside of userdata, that I reflashed multiple times from multiple sources, to have any type of recovery (stock or custom) not work is a bit upsetting. Since it works fine on the older bootloader, it definitely seems to be an issue with that. But since most people do not have the same issue, the only variable I can see being the difference is hardware.

It looked more like a warning symbol that something went very wrong then a stock recovery screen.
I've gone into stock recovery on other Android devices before, and it looked similar to CWM. There was a menu that allowed you to install "authorized" update.zip files, factory reset the device, etc. There was no menu here, just a very pissed off and sick looking android guy .

I believe I am having the same issue. Would you mind linking me to the bootloader which worked for you? Tried searching but couldn't find it. Thanks, and great post!

There's a big thread around here somewhere with people having the same problem as the op. Unfortunately, staying with the 3.34 bootloader is the only 'fix' I've read about. I still can't figure out why some people run into this problem and some don't. I used twrp to flash the update when it became available, and twrp continued to work afterwards.

It took me a long time to find the old full JRO03D update, since Google only has the latest one on their page. I uploaded the bootloader out of it and you can download it here:
http://core.routed.com/bootloader-grouper-3.34.img
Reboot the Nexus7 into bootloader mode and run:
fastboot flash bootloader bootloader-grouper-3.34.img
fastboot reboot-bootloader
and then you should be able to flash recovery and get into it.

The android with the red triangle does not sound like the stock recovery, it is THE stock recovery.
Under JB 4.1.2 you do not need anymore to connect the N7 to a computer - like it had to be under JB 4.1.1 - to access the bootloader and then the recovery.
Now, pressing volume + power brings the bootloader , the up volume, one press, and then power press put the N7 to recovery. The recovery is the android with the red triangle. To enter in the recovery menu pressing power + volume up brings the menu with the following options:
i) reboot system now,
ii) apply update from ADB,
iii) wipe data/factory reset,
iiii)wipe cache partition.
Concerning specifically the OTA update for an unlock and root N7 there should be no problem during the process using stock recovery or CWM 6.0.1.0 as long as OTA Rootkeeper is set, before the installation, in order to keep root.

the fact that you were able to do volume down + power button into bootloader, then select recovery, makes me know its working. and the android guy on his back is the stock recovery... so everything is working fine. you said you flashed motley kernel, it may have something to do with that, and a few other things. you really need to understand how the N7 works, and what it will do if you do not do certain things.
what u should try is, fastboot flash recovery, then fastboot boot recovery
flash a different rom, i prefer Paul's Jr8 as its close to stock with nice little tweaks and see if your issue continues.
at the end of everything, i honestly find this more user error then device related. not everyone understands what the N7 is doing, and why.

Smirkis, my initial thought was that something went wrong in the upgrade process, possibly with the kernel like you suggested, so, as I mentioned in the OP, I flashed everything back to stock 4.1.2. I used flashboot to manually erase boot, cache, recovery and system. I then reinstalled the bootloader from Google's update tarball. I then used fastboot to update to image-nakasi-jzo54k.zip. At this point, outside of wiping sdcard, everything was stock 4.1.2.
While I will admit that I didn't realize that the dead-looking android meant stock recovery (and that's good to hear), subsequently flashing a custom recovery (CWM or TWRP) would continually fail to load it. In fact, I couldn't even boot into the recovery manually without flashing it. While using 100% stock, I attempted to flash three different versions of CWM and one version of TWRP. It claimed it updated, but I was not able to get back into recovery - either through bootloader, adb or "reboot recovery".
I know it's easy for people to always jump to the "user error" answer, but I fail to see how that is the case here. Based on your response, I don't think you actually read what I did and just jumped to the wrong conclusion, especially since I already tried your recommendation and much more. I am not running any custom ROM - everything was always stock outside of recovery, root and kernel. If you can explain your reasoning for thinking I did something wrong in all of my numerous attempts to get it working, I would appreciate it since maybe that would provide a solution. While I did attempt to use a custom kernel originally, that obviously isn't the issue if going back to stock didn't fix it.
Additionally, reverting back to the older bootloader magically fixed everything, while all other attempts failed. Subsequently reinstalling the custom kernel didn't break anything either. So if it wasn't the bootloader and something else was broken, I would assume it would be broken in both versions of the bootloader. The fact that this problem is affecting others, granted a small number, and the same solution works for them, leads me to believe that there is either a bug in the bootloader affecting some N7s or some rare HW defect causing a few of us problems.

There is a conversation about the new android update the boot-loader update and A Power management chip on the nexus 7.. It seems this chip is being changed out. The new chip functions the same as they have been using but Its not compatible with the old boot-loader . The above is the reason for the boot-loader change.. Google is aware of the troubles everyone in this thread is having . I would be looking for a new very tiny update in the near days. Just a guess im wondering if the truth is they are gearing up for the 3g version of nexus .maybe the pm chip being changed has a issue with the added radios. They did say ITS NOT A Chip upgrade but will not say why they are making the switch .
sorry i do not have a link . but everyone knows how to get to google groups ..
Happy Reading..

I just got another N7 in the mail today, gonna unlock n root it when i get off work. hopefully i end up in your situation so i can attempt to assist in resolving this. why the old bootloader works for you, and never worked for the rest of the world is beyond me. they updated it for a reason lol, i even called google the first week i got mine in july to tell them about the bootloader and they "said" they would forward that info to the development team. it took almost 3 months for them to fix it.
if the old one works for you, then use the old one. the only difference really is the fact that reboot to recovery thru bootloader actually works. if it works for you, don't upgrade.
mine on the other hand, couldn't get into recovery via bootloader. i was dieing for that upgrade, and when it came i was beyond relieved. i did a RMA this week because my first one had screen lift since the 2nd day i owned it lol, so i'll report back when i get home in an hour or so on my results.

Just to clarify, going from bootloader->recovery never worked for me either. Whenever I needed to get into recovery mode, I just opened up a terminal, su'd to root and then ran "reboot recovery", or occasionally doing it via adb. However, those methods always worked for me until I upgraded to the latest bootloader. Then, no custom recoveries would load via any method.
My Nexus7 was first generation. I actually picked it up in Sams Club the day before they were officially released. So if Google made any HW changes in the different revisions, that might explain the difference in results on 4.1.2. Though I imagine most people on XDA also picked theirs up out of the first batch, so I don't think that could be the case. What seems more likely is that there are minor hardware differences that are causing some people's to fail with the 3.41 bootloader, while most don't have that issue. It will be interesting to see if you experience the same issue on your new one though.

It didn't worked for me. I've tried Rootkeeper apk, but it was useless.
This was driving me crazy until I've found this topic! I've tried resetting it to original settings, using rootkeeper and traditional methods, nothing, zero!
At last, phonic saved my life, and finally I a could root my Nexus 7!

I never responded but my RMA worked as it should. but the issue has been resolved with recovery updates from the developers. the rest of the world who had issues should be good to go. I ended up selling my 16gb unit and got a 32 and it works as it should as well. are we all happy campers now?

I've had similar experiences where the way certain kernels install zips are packaged, the wipe custom recoveries at install. In that situation, I've never wiped anything from system, but rebooted into bootloader and fastboot boot recovery "recovery.img". Then from there install the recovery.zip. The worst is when this happens when you get flash happy away from home and the kernel doesn't work. No way to fix without a comp w/SDK. Glad you're back up and running.
(I cannot be held responsible if the aforementioned damages your device; do the research and own the process.)

I am so glad to have found this thread. This problem was beginning to drive me nuts.

[SOLVED!] Bricked Nexus One

Ok so I think I've bricked my Nexus One. Everything was working perfect until I re-rooted it (to have SetCPU to work). I am now stuck at the loading animation screen (Google Nexus One "X"). It just keeps going and going and going. I've even tried loading my Nandroid backup and still does the same and won't work. Also I've wiped to factory default settings and tried to reinstall Modaco's 1.3 rom.
Someone please help me out...
Flash bacon add-on on top
bye!
So reinstall Modaco's 1.3, then install Bacon Add-On, and then reboot?
Yep That's the solution for some users
ok cool I'll give it a shot right now... I really appreciate it
ok at this moment it's still stuck on the animated screen... now I really don't know what to do...
Try flashing the stock rom
if u have the sdk installed, the run ddms. power on the phone usb connected to pc and see the log in ddms, paste-bin here
I have no idea on how to do that... I'm pretty much stuck at this point
try not flashing Modaco's Rom,
just flash CM's bacon
i think there is a confusion because Modaco's rom is in the rooting threat (made me believe you HAVE to use Modaco's superboot and then go to CM's bacon.
reality is you don't need modaco's superboot. after bootloader unlocking and flashing Amon Ra's recovery image you can go straight flashing CM's Makin' Bacon.
It seems people have been successful with CM's
maybe just go straight back to the start, check that bootloader is unlocked, flash amon ra's recovery, then flash Makin' Bacon
good luck

WOW, I really appreciate it and that just worked for me. Thank you to the both of you guys!
if you can get into bootloader mode (this is the lowest level mode you can boot into), you can not brick. Even more so if you can get into recovery (which is usually always possible if you can get to bootloader)
Good you found a way to get out of your situation.
Like i said in Android 101, you CAN NOT brick the phone unless you are updating SPL and Radio. All other stuff is just a minor inconvenience.

glad it worked and it confirmed my research - so i can go at it with ease once i can
This is good news. OP, you should update your thread titled with the prefix [SOLVED].
ahh how'd I miss that 101 sticky... thanks for the heads up again guys.

Am I bricked?
Ok, my issue is that I cant boot into bootloader or recovery (I tried booting with rollerball pushed in, booting with down volume, abd-mac reboot recovery, abd-mac reboot bootloader) and it just goes right into my OS which is crashing every few minutes, and my radio wont work. Any suggestions? If I am bricked, can I send it to HTC even though its rooted and bootloader is unlocked? I dont care if I have to pay for fixing it.

First of all, if your phone boots at all, it isn't bricked. A brick is a paperweight - it doesn't do anything. Second, this thread of 5 months old. Third, people have talked A TON about sending phones in to HTC with an unlocked bootloader, do a bit of searching.
And finally, it is very peculiar that your phone doesn't boot into bootloader or recovery. Try plugging your phone into your computer, opening your command prompt, navigate to your adb install direction, typing "adb wait-for-device reboot bootloader", and turning on your phone. Best of luck!
People should be banned for bumping 5 month old threads with posts not even related to the OP's post. Ridiculous.
@rcxquake: thanks for your suggestion. That didnt work, it just rebooted the OS. Ill keep searching for my solution and how to send to HTC if I cant find the solution.
@GldRush98: Sorry for ruining your day. I put in a google search for what I was experiencing and this was one of the top result of anyone remotely close to my issue. Yes, this is an old post, but maybe someone had this issue months ago, and had a solution I wasnt aware of.
And like I said, I found this post, although not exactly my same issue, was as related as Ive been able to find. I didn't find it so ridiculous.
If you can find my same issue on another post, then please help by pointing me to it so I can find my solution. I didn't mean to cause any issues.
Thanks
I for one am glad you posted. I don't know whether this is a solution for you or not, but I'm sometimes only able to get to the bootloader after I've had the phone off the charges, with the battery out, for some time. It varies for me between a few minutes and many minutes. It is hard to say because when I try and it doesn't work, I don't know if I've reset the time by having tried.
Anyhow, I found this thread because I'm having trouble with an N1, and one of the earlier posts may help me. Thanks for bumping the thread for my benefit.

You've probably heard that from idiots who don't know what they are doing.
The latest version of TWRP works perfectly fine with 4.2 (3G and not). I'm using it on my 3G without any issues.
And the previous 'su' binaries and apk's should be fine. Neither of them should cause any problems with the 3G functionality as they have nothing to do with it. I installed custom recovery and rooted mine the day I got it. Everything is perfect.
Also, absolute worst case scenario, if you do screw something up, it's easy to revert without losing all of your data.
Hmm...I don't consider myself an idiot but did nothing more sinister than root and flash CWM and lost cellular data functionality completely at random two days later (unknown baseband). Had about 6 Android devices before this going back to HTC Hero, flashed all sorts, and never seen anything like it. Eventually had to flash factory image to get it back. Not especially helpful as inexplicable and not reproduced but worth saying nonetheless.

FYI, there seems to be a sporadic bug in JB on my GNex where on certain reboots it says Unknown Baseband and IMEI in the About menu, and then on the next reboot it's fine. I am wondering if that same bug is cropping up on the N7, and it's just coincidentally happening on some people's devices after rooting, but it goes away later. On my GNex this issue is particularly noticeable if I gave the phone a full reboot from inside software (e.g. using the app Easy Reboot). Whereas a power off / power on does not as frequently run into this issue.
I'm looking forward to getting mine Ordered today and it shipped today! I'm going to give my 16gb (bought in Aug for $249 so no price mod for me ) to either my GF or my daughter. lol
Sorry for the OT post.. I'm just excited. It will be nice to not have to tether my N7 to my phone. I just switched to the shared data plan on AT&T so it will only cost me $10 to add the N7 to my plan
Just fired up my 3g and will root it tomorrow, is there anything really different in rooting this thing vs the 16gb, anything I should watch out for?

No, they are identical from a rooting perspective. However, they do run slightly different versions of the image, so if you wind up flashing stock, use the right one.
so first my success, i have managed to get root and a TWRP recovery.
now my question in menus im seeing horizontal lines that move with the landscape. so as the phone rotates the screen, the lines also rotate. maybe its just the background design but it seems really awkward to me that they would intend from these lighter brighter lines to be there

I don't have my N7 yet, but on most Androids the stock recovery images do not vary much or at all between minor upgrades, so any stock recovery should be fine. Try the recovery.img inside the JOP40C image straight from Google. https://developers.google.com/android/nexus/images#nakasigjop40c
Worst case if the update still won't take, flash both system and boot from the stock image too (this will unroot you but so would the OTA, and you can fix that later), and then you'll be stock enough for OTAs to work the next time it prompts.

im pretty sure the "recovery" partition doesn't contain any of those things. i don't want a stock rom, i need stock a recovery. twrp allows you to back up certain partitions such as boot, cache, and recovery

i just downloaded that ill try flashing it now i downloaded the "Google Nexus 7 Toolkit" and while it didn't work for me, it did provide a JRo03d stock recovery which i flashed with fastboot and that recovery did not work. when you nexus 7 arrives i believe it would be possible to recover the stock recovery using "fastboot boot twrp-recovery", ALTHOUGH im not sure when you would execute the "backup recovery" if it would read the phones actual partition or the image you uploaded and booted on

Sorry for my quick answer, I haven't seen the "recovery.img". that's file system.zip or tar which contains apps and data for restore
And if you want the Factory image, go to the thread : [Index] All for NEXUS 7 - "nakasig" - (GSM/HSPA+) , it is on, ready for download
ya i grabbed it thanks. what i don't understand is what the 34mg update is for? any ideas? i uploaded two shots, one settings page showing the build mine shipped with and the other is just the update screen i got showing size. Im about to flash the stock ROM from google now. we'll see how goes
the 34mg update was "signed-nakasig-JOP40C-from-JVP15S". i was able to flash the recovery from the stock ROM JOP40C and use that to patch through android and avoid flashing usuing TWRP

im pretty sure the "recovery" partition doesn't contain any of those things. i don't want a stock rom, i need stock a recovery. twrp allows you to back up certain partitions such as boot, cache, and recovery

Honestly don't try toolkits. Just don't, because you don't know what commands or files they are really flashing, and especially because they were written for the wi-fi version. The stock recovery from the wi-fi version is not guaranteed to be compatible with the 3G version.

System.img is also devoid of personal information because to the standard end user it is write-protected. All the personal stuff is in the data partition.

Glad it worked out for you. I had a feeling it was just going to give you JOP40C anyway.
So, I have been trying to root my 3G tablet (JOP40C), but have no luck. I installed TWRP and unlocked just fine using the Google Nexus 7 ToolKit 3.2. When I use the toolkit to root it seems like it is doing everything fine, reboots, and I do not see any errors during the process. However, when I access Titanium backup, or Root Checker it cannot gain root access. I have tried all the options in the toolkit and nothing is working. Can anyone give me some pointers? Thanks!

Yes - Don't use a toolkit!
Since you already have a custom recovery, put the attached file on your sdcard and install it using TWRP. Then you should be good to go.

[Q] PASSIMG.ZIP Really Screwing Me Up

I've rooted my Nexus One a long long time ago, and eventually reverted to it's original state. Let's skip ahead a year..
I wan't to use my Nexus One again until I can get my hands on a Nexus 4. I'm trying to root this bad boy, but run into a problem with every method. I got the one click method to work, but it wouldn't boot up. And when I try to go into Bootloader for recovery, it checks for the PASSIMG.ZIP file and then updates. If I click no, it makes no difference, it doesn't let me do anything. Updating will restore the phone to stock(unrooted). So I deleted PASSIMG.ZIP from the SD card. Ever since, I can actually click on Recovery, but I run into trouble(see further below). S is ON btw, I don't remember what this was, but I'm sure I had it OFF before? I have been using an iPhone for the past year and a half, so I apologize for being a noob. I'm not to tech savvy when it comes to these terms, either.
Short explanation:
One Click Root - I can root it, but when I go to Bootloader Recovery it shows the Android guy and a triangle around !
Using the old school method using Windows terminal, recovery-clockwork-5.0.2.0-passion.img was flashed without problem.
But I can't access Recovery!
In the end I'm trying to at least have an ICS ROM, or Jellybean(Really wanna try Google Now or whatever) if possible.
Check the Wiki for instructions on how to bootloader unlock your phone. Much easier. You can then flash everything you want using fastboot (so make sure you have the fastboot driver installed correctly).
Btw, the triangle means you still have stock recovery.

The unlock padlock icon means the bootloader is unlocked, correct? I've done that. And I actually went through that, and flashed the custom Recovery, still the same result. I'll retry it again.
I figured it out, but I don't get it...
I did this in kind of a different route, so just incase someone runs into a similar problem some how:
I rooted the phone using the one click root software on a windows PC, the N1 was successfully rooted.
However, same error recovery, even after adb flashing recovery(followed wiki and unlockr tutorial).
What I did different to fix the issue, was after the root, I downloaded Rom manager(yes I've done this before too, but...), I flashed the recovery via Rom Manager. After it didn't work(sadface).
I tried it again, but just out of frustration I re-flashed it after flashing. So I flashed the recovery twice, back to back. And poof, I check bootloader, go into recovery, and there it is(just like it used to be).
Close this I guess, (an embarrassing)problem has been solved.

Please help. Phone stuck in purgatory [Resolved]

Okay, so being the wise person that I am, I decided that it would be a good idea to get the 4.2.2 sense update a few days/weeks before my carrier (Rogers) pushes it. I'll write it step by step, in case anyone can help me
- I started by making an ADB Backup, rooting the phone, and installing twrp recovery. No issues there
- When the phone started back up, I tried to restore my data, but the adb backup kept getting stuck on "com.Android.contacts" or something similar, so I decided I might as well try getting S-Off so I could change CID and get the 4.2.2 update.
- I used Revone, but it kept failing (error code -1). I posted in that thread about it, but I decided that in the mean time, I would just factory reset my phone.
I stupidly clicked "format" in twrp!
Now, my phone is on twrp with no OS. I tried downloading the rogers rom from HTC Dev, but it was a Zip file, and it won't install. I restarted the phone, and now I can't push anything to it. It says "error: device not found" when I try push the European 1.28 RUU (which I'm not sure if that would even work, because of CID/MID differences since the phone isn't S-Off.
Any help would be greatly appreciated :crying:
Okay, So I finally got the European RUU to push to the phone, only to realize that it's a ".exe" that can't be flashed from twrp. I have no access to a PC

Just flash any stable ROM in the meantime so you can at least boot the phone. Download ARHD, push the zip to your phone, and flash that.
I really don't understand all these people changing CIDs to force updates, especially when they go back to s-on afterward. You're locking your phone into a potentially problematic configuration. I helped another guy this morning who did it and then couldn't boot up but couldn't fix anything because he went back to s-on and locked bootloader.
If you want 4.2.2, do it the right way: S-off, flash firmware, flash rom. If you want stock, there are stock roms. All of this can be done on a Mac.

Well, I flashed CM 10.1, and finally managed to get S-Off. Now my issue is trying to go back to stock HTC Firmware. I can only get the RUU, which obviously doesn't work on Mac. Even If could extract the Zip, I have twrp recovery. How would I go back to a stock recovery that would allow me to get the OTA? I'm really upset about this whole thing. I mean, come on. HTC should've provided a Mac utility that allows users to go back to stock completely. I understand that they give you warnings about doing this kind of stuff, but I should be able to play around with my device and still be able to get it back to a functional factory state. I got iOS 7, and it was incredibly easy to go back. I've upgraded my Blackberry Z10 a 100 times with firmware from all over the world with no issues. I've also never had to deal with this S-crap stuff on my Nexus 4. It's just frustrating for end users.
Anyways, rant aside, would you happen to know how I can go back to a full factory state? I'm on CM 10.1 right now with twrp recovery.

Without a PC to run the RUU, I'm not sure. You can flash stuff, but if you want to be out of the box stock, you need a RUU.
I finally managed to get my phone to work. In case anyone comes across this, I'll write down what I did.
I had too many problems to list. From not being able to access adb on the phone, to the phone's memory being partitioned incorrectly, to the point where even a recovery like twrp couldn't format or access it in order to flash anything ("Unable to mount internal storage").
The solution to all problems (and if you're a Mac user like I am, this is disheartening), is that you'll need to run RUU on a PC. When doing this, you'll likely run into a few error messages.
Error 170: Make sure the device is in fastboot mode before plugging it in (hold power and volume down on boot, and select fastboot with the power button). You can make sure that the computer can see it by going to your device manager in windows, and make sure that it says "My HTC" under "Android Device." If it has a cryptic name with an exclamation mark, or you can't see it by using "fastboot devices" command, you'll continue to get that error.
Error 171: This error kept occuring when the computer could no longer see the phone after the process had already begun. The reasons this happens are many (ie your USB wire or drive might be faulty), but to me, it was because the phone was not going back to the bootloader on its own, and the computer eventually gave up. To solve this, start RUU.exe and WAIT BESIDE IT. You will come across 2 points where it says waiting for bootloader. Have your computer's device manager open, and hold the phone's power button until you see that the "Android Device" or "My HTC" disappears and reappears. RUU should continue when that happens. Again, you will have to do this twice! If you don't, RUU gives up on the phone as it does not go into the bootloader by itself, and will eventually give you an error.
For anyone going through this, just realize that as long as you can get into the bootloader, there's always a way to get it to work. At times, I thought my phone was completely bricked, but no matter what issue you have (including unable to access the phone's internal memory), you can always solve it if you can get into the bootloader. With that said, this process will erase everything on your phone, unfortunately. Everything is done at your own risk, so please don't blame those who are trying to help you. Good luck, and remember to always post your solution online, if you start a topic discussing the issue. I came across many people with the same issue who never came back with their solution!
Edit the title to solved
Not that it has happened to me but I think you could have just sideloaded a custom Rom from twrp and flashed that.

That was one of the first things I tried. It kept coming back with "unable to mount internal storage" or something like that, as I noted earlier. It was really weird, I couldn't format, mount, or do anything to my storage with tarp, and I couldn't get adb to see the phone. A lot of people have the issue with the One X, but I couldn't find a solution anywhere. I think what made the whole thing trickier than it needed to be is the fact that I changed my CID/MID, and in that guide, it is explained that you have to reboot the phone yourself in RUU, but I didn't realize not doing so would result in errors. I kept thinking it was because my device wasn't being seen in adv, so I was trying to get it to boot into any ROM for that to happen, and the inability to flash anything due to the internal storage error really complicated things. It's good to know that even this can be resolved, as I had all but convinced myself that I was dealing with a brick. I hope anyone coming across this issue in the future can benefit from my ordeal.

[q] phone stuck on bootloader unlocked screen dont know what to do!!!

I had a problem a few days ago that i was having problems after rooting my phone so i brought it back to stock using RSD Lite and then tried to flash a new rom on the phone and it said my phone was not unlocked so i downloaded The Myth Tools and unlocked it that way but I am wondering if i messed it up because i did not really know what i was doing i just tried to see if i could figure it out and it seemed like it worked until today. I flashed Touchwiz on there a couple days ago and it worked fine i made a backup wiped the cache,dalvik cache and system now today it randomly freezes and is now stuck on the bootloader unlocked screen. I can hold down power and volume up and boot into recovery which is ClockworkMod Recovery v6.0.3.6 touch and it also says under that in the bottom right of the screen Warning No file_contexts now i dont know if it has always said that since i flashed this recovery or just started. I also once again tried wiping the cache and dalvik cache because i read it on another post of someone stuck on this screen so i tried that and rebooted it still the same result stuck on bootloader screen. At this point i have no idea what to do. If i have to start over from stock because i messed up unlocking it or completely wipe it again and reflash touchwiz or another rom. I have had nothing but problems since rooting this phone I have gone through atleast 6 to 8 roms because every single one of them gives me a problem somehow. The most common is when i make a call or recieve one and i put the phone up to my ear I know the sensor turns off the screen but when i take it away to end it or do something its completely off or apps force closing all the time still after i did the stock reflash. I am starting to wonder if its just my phone because everyone else i read about has no problems with there phones mine nothing but problems. Please if someone could help me or walk me through this process it would be greatly appreciated I love the things it can do with custom roms but i just wish it would run smooth.

You can enter Recovery, right? What happens if you install a .zip? Right now your phone is stuck in the Motorola logo?
it wouldnt even go to the motorola symbol it just stayed in the first screen where it said your bootloader was unlocked. It would go into recovery and i tried to reboot it and it gave me the same screen. So i wiped it completely cache, dalvik cache and system and shut it off. Last night i plugged it into my comp to put it back to stock and it started up like normal and booted into a rom like i just installed one where you have to fill in all that info and setup wifi if you choose too which was weird because it wouldnt do anything before. Anyways i used RSD Lite and put it back to stock and thats where it is now. I am reading the Atrix HD Beginners Guide written by skeevydude right now and I am thinking about trying to root it again with the help of that article and maybe I will have better luck doing it that way hopefully haha maybe I can finally get a rom to run the way everyone else says they run smooth and fast. Any input though to help me would be much appreciated i am definitely new at this and want to learn its something that interests me alot ever since a friend rooted my phone the first time i cant stop playing with it I was trying to make it as fast as I can I had ProBam on there i think its called ive had touchwiz, motoblur, carbon, liquidsmooth, MIUI, and a couple others I cant remember also had a custom kernel i flashed on there and Pure performance so as you can see I have been trying everything.

Good to know that is working now. I would recommend you to take it easy. Don't flash it everyday, use and know a ROM, then you can decice which one is better for you. Be sure to have a backup if something fails, also save a .zip (ROM) in the SD card. Just FYI, I haven't come across a ROM that is 100% smooth (Not even HoloBlur). They are very good, but maybe not the smooth level that you think.
Hey bpc87, I was wondering if you were able to get a custom ROM up & running after all that & if so, how?
I've had the same issue whenever I tried installing a ROM. It would install & boot okay the first time, but when rebooting, it would get stuck at the "bootloader unlocked" warning screen. I went back to stock using Myth Tools & now, after installing a ROM, a reboot leaves me stuck at the "Motorola Dual Core" screen.
Any help from you & the community would be awesome!

dude i havent even tried to since i flashed it back to stock because i dont want the same thing to happen. The last time I just went to turn on bluetooth and it just rebooted on its own. Not too mention the other problems I had I am not going to mess with it again until I read more on how to root it because it is either that or my phone.
Yeah, I understand. Hopefully then some other users who run into the same problem will investigate & figure out what's goin on. I've seen several other threads of people who've encountered the same thing but unfortunately no answer. For me, this is the determining factor as to whether I end up keeping the AHD or not.
Thanks
I have the same problem. Everytime in moto logo after rebooting, but with stock firmware all ok. Is there any solution for this problem?
