close to brick (coby 7015): how i got out of a pinch

Here is my story.
I found a patch that was supposed to give me ad-hoc on my coby 7015. i don't quite remember where i got it but i believe it was in the xda forums. well i'm not sure if it wasn't written correctly, was malicious, or if i didn't read the details correctly but i tried to install it. this also may have had a part in why things went south. I first tried to use the regular recovery util to install it since the zip was called update...w/e that didn't work. i then switched to clockworld recov to install and i used the apply update from sdcard setting...didn't look at when it was installing i just rebooted and kept moving ( i was at work and pressed for time).
when i realized my wifi wasn't working anymore i tried to install it again realizing maybe it was the way i did it, so it stead of the "apply" option, i used select zip to install. still the same problem...
after all this i decided the best thing to do would be to
1. see what was updated in the file: only thing i saw other than certs was the wpa_supplicant file
2. find an original version of said file and replace it: I did this via WinVista instead of terminal for couple of reason the primary being that i couldn't remember the command to copy/paste in linux and i wasn't sure if the terminal could extract and re-zip files.
so plugged into the laptop i pulled files and tried updating first in the regular again, then in clock world with similar results and the same problem.
Ieventually tried posting a question on the linux forums because it was quickest and i usually get fast answeres, however, i was impaitent so i ended up doing the most fatal part of this. I decided to do a factory reset.
I started with the main recovery util and used the reset:
1. i still had the same problems with wifi
2.ALL my APPS (including my emulator and root access, the most important of al my apps)
I then tried the UI factory reset and got nothing.
Becoming frustrated I tried really just a freak, last ditch attempt. used the coby update found on there site and it fixed the wifi. I am now lacking Gapps and my other apps but i can now get those back cuz i have wifi....whew

Fixing LG vortex bootloops

I recently had a problem on my LG vortex. I had rooted and deleted some bloatware, then because I was upgrading phones, I thought I might sell my vortex for cash. So I did a factory reset. Much to my dismay I shortly found out that I had accidentally deleted the home screen from the phones factory memory leaving me in a boot loop. even a hard reset using default recovery wasn't working. After a day or so of research I found a couple of guides:
LG vortex downgrade guide - many thanks to Salem, as much of my guide is copied from his
http://forum.xda-developers.com/showthread.php?t=883314
after a bit of tweaking I was able to recover the phone by following these steps:
Disclaimer: I am not responsible for *any* loss or damage (including bricking) to your device -- use this guide at your own risk!
[Setting up your computer]
if you previously downgraded your LG vortex from 2.2.1 to 2.2 chances are good this part is already done
1. download files from following links:
factory flashing software & firmware
optional free un-rar software
2. plug in your phone (even in it's crippled state) it should autorun, and install some USB drivers
3. extract LGNPST.rar and run the LGNPST_General_v1.2_Lab_Version.msi this will setup to the directory C:\LG Electronics
4. copy/move LGNPST.exe to C:\LG Electronics
5. extract the LGNPST_Components rar file, this will make a directory with two MSI files in it - run these.
6. Go to C:/LG Electronics/LGNPST/ and create a folder called “Model”. Inside that folder, create another folder called “LGVS660″.
7. Extract LGVS660.rar. Inside this, you’ll find a VRZ folder. There are three files inside this: a .tot file, a .scr file, and a .dll file. Move these all into C:/LG Electronics/LGNPST/Model/LGVS660/ (the folder you just made.
8. If you’re on Windows XP, hit start, click on “Run”, and run this:
regsvr32 "C:\LG Electronics\LGNPST\Model\LGVS660\VS660.dll"
If you’re on Windows Vistas or 7, hit start, type cmd.exe, right click on cmd.exe when it comes up in the search area, and run it as an administrator. Type in the following and hit enter:
regsvr32 "C:\LG Electronics\LGNPST\Model\LGVS660\VS660.dll"
[setup complete] your computer should now be ready to fix your phone
Contrary to popular opinion on the many forums I perused researching this, I found that this software does *NOT* require your phone to be in debugging mode! it will see your phone if you simply plug it in at this point
[Flashing the phone]
1. go to C:\LG Electronics
2. run lgnpst.exe
3. if you haven't already boot phone and connect USB if the phone was already connected disconnect and reconnect it to make sure the software recognizes it.
Warning! do not disconnect your phone from the cable under ANY circumstances until the software tells you it's safe to do so!
4. try to directly flash phone back to factory. This will require you to select the .tot file from above under where the program is expecting a .bin file (you'll have to manually type in a filter in your file selection box) also select the .scr file in that same directory.
5. if that doesn't work go to the Data menu
6. select 'data recovery'
7. let that work it's magic and it should transfer to 'emergency mode'
8. select the .tot file and then the DLL for your phone
9. flash -- if everything works out your phone will reboot around 60% with everything on it
10. once the phone has booted completely go to menu and set phone to USB debug to stop the 'flashing' process this will allow you to safely disconnect your phone
ENJOY!!!
[emergency flashing]
*WARNING! the following methods are untested! above methods worked for my phone!*
Once again, do not disconnect the phone under ANY circumstances until the software tells you it's okay to do so!!
1. boot the phone in emergency mode by holding volume *up* and the back button at the same time (as I gather from the above mentioned xda post)
2. once in emergency mode it should be safe to continue from step 8. above.
[end guide]
Many thanks to those out there who helped me build this guide!! I hope it helps!! Now you should have the freedom to try removing all that bloat ware again. Hopefully, with a bit more discretion this time
In case anyone is wondering -- yes, I'm a n00b, and yes, this guide is for n00bs just like me

Advice?
Can this method be used to return a rooted/hacked/modified phone to FULL factory stock so you can return it for a warranty claim? IE- will it remove clockworkmod, superuser, and any other traces that you messed with the phone? Also, is this for verizon?
I had a lg vortex I had to return recently due to a blown speaker making my calls sound like a kazoo.
I DID root it (using gingerbreak)
I DID run some sketchy root programs like setcpu, wifikiller, root explorer, wifitether, and a few others
I originally ran ROM manager to backup my rom when I first rooted, but it said it installed clockworkmod (selected LG optimus V from the list and it worked) in order to run properly.
I have slowly uninstalled all of the software, used rom manager to restore my first backup, then uninstalled rom manager, installed gingerbreak, unrooted, uninstalled gingerbreak, uninstalled everything, then did factory reset from settings menu.
As of today the phone looks stock. No superuser. No sketchy programs, I'm just not sure if CWM or something else could have survived the factory wipe from the settings menu. I know superuser survives a factory wipe, so I'm not sure if I still have dirty files lying around. If verizon knows I rooted my phone it will cost me $309
Is that good enough? I don't want to return a device that has evidence files on it, but I have no clue if clockworkmod got uninstalled with rom manager or not. I never changed roms, I never knew how to boot into cwm, I don't know if it's still there or not. Advice?
EDIT: You should note that my phone is NOT bricked- the speaker is blown, so there should be no limit to the menus, functions, or software tweaks available which would be needed to fix my situation. Also it should be noted that I am not the type of person who condones returning a bricked phone to get another one- That hurts us all. Unbrick yourself using a thread like this or eat your mistakes.

hi, I recently rooted my phone with gingerbreak and uninstalled some bloatware from verizon. Then I couldn't see the home screen, although I can pulled down the status bar. After following your steps above and at running lgnpst.exe. I got the error message saying: Fail to load the Skin.dll. Do you have any idea? Thanks

been looking for you for three solid weeks!
dude, i've literally tried every posted forum in xda, androidforum, soul, phandroid, etc, downloaded every possible software, updates, utilities, recoveries, firms, and yada, yada, yada, and for the past three weeks i have past this one flippin' thread, over (no lie) 20 or so times. and please believe that your solution/explanation for this problem was really my last @#$#@## time i was going to EVER, and i mean EVER, download, install, re-install, re-name, re-write, place, copy/paste, throw-up, stroke, stomp-feet, and dosie-doe anything technology-based/wired-wireless eqipment in this young mans life again!!! so i thank you:victory::victory::victory::victory::victory::victory::victory::victory::victory::victory: and to ALL those not mentioned here (my apologies, but are still and forever will be in my prayers) for this and every single solution/explanations, that has ever been posted for dumb-a#$es like me. and for donating im trying to do that but recently messed up by using google's new/terrible wallet proccess. yes i know i should have used "PAY-PAL" but had already had money link to that GOD-aweful--theivery account. and for all those out there like me/us i will be posting my own thread/solution to this very same problem using my own words in a more in-depth description including all-props to you and for them not mentioned here (my apologies, but are still and forever will be in my prayers). thanks to you all and fyi im stopping here, oh no, i too, will become a master of all this hacking stuff, or i will become a master of destroying them all and then will have new problems for ya'll real hackers to nibble on.!!!

[Q] Apps will not update, device won't shutdown

Starting about two weeks ago, Google Maps app would begin launching itself periodically after opening any new apps. Then I started getting a notice when Hangouts was trying to update that "The package file is invalid" or something like that. That eventually became apps never finishing updates. This is especially noticeable with Google apps (Hangouts, Newsstand, Play, etc); they get to some percentage of completion and then just stop. (The percentage ranges between 37% [Newsstand] and 91% [Chrome]).
Cleared the Play Store cache and data and attempted to reboot, but the device would not shutdown. It cycled through the various shutdown prompts, then the shutdown spinning icon appeared.... and it stayed like that until the battery drained. Re-started after charging, nothing was fixed. Tried shutting down again, same problem. The only way it becomes responsive again is to hit the little hard reset button.
Did a full hard reset to factory spec, none of the apps will download updates at all. And when the device is fully booted I get a barrage of error messages saying that various Google apps/services have stopped working. (i.e. "Unfortunately, Google Maps has stopped working." or "Unfortunately, Google Play Services has stopped working.")
Device is a stock 32gb TF700T running I think 4.2.1 JB, with a 32gb SD card to which nothing has been written.

What do you mean by you did a "full hard reset"?
First, copy all data you don't want to loose off the tablet.
Then you can try to clear cache and data on everything Google. Go to Settings > Apps, swipe until you see All, then go to town: Maps, Hangouts, Services framework, Chrome, Play Store - the works.
Then go to Settings > Accounts and remove your Google account.
Reboot.
If it still hangs, try holding Power and Volume Down button together until the tablet boots into the bootloader menu.
You'll see 3 icons. Push Volume Down until "Wipe Data" is highlighted. Then press Volume Up.
It should reboot once it's done. If it returns you to the bootloader menu, use Volume Down to cycle to the Android, then hit Volume Up to boot the system.
If all that does not do it, you can manually reflash the Asus firmware or - even better - unlock the bootloader and flash a custom rom.

First, thank you for taking the time to reply. I appreciate the help.
And for what it's worth, the problem as evolved since I posted this; now, as soon as I power or wake up the device and enter my PIN, I start getting error massages that a variety of Google services have stopped working. Always Maps first.

This is what I meant by 'full hard reset'. Apologies for using confusing or incorrect verbiage.

Okay, gave this a try. Still would not shut down on its own, and I had to hit the little reset button on the side. Got back in, added one Google account, attempted to update apps, and I get an error saying: "Update for [app name] could not be downloaded due to an error. (Error retrieving information from server. [RPC.S-7:AEC-7])" So I deleted that account and added another one. This time the Play Store wouldn't even show me the installed apps. White screen, spinning circle of sadness.
I don't know if this makes a difference, but I did not indicate in my original post that I have three different Google accounts on this device. But only one of them is the one used for downloading apps to this device.

If removing anything Google doesn't help, I would start fresh: Reflash the firmware following the steps under Alternative Install Method here: http://forum.xda-developers.com/showthread.php?t=1755576
Then set it up again with just one Google account. That should do it.

I attempted to reflash using the steps outlined at that URL, but to no avail. The update isn't recognized (perhaps because I'm already on that build number?), and the rar file does not launch.
At this point, I have two options: Install a custom ROM (can't really hurt, right?), or just get a new device. Considering ASUS is not updating the firmware anymore, meaning 4.2.1 is the highest OS version I'll ever run on it, I'm sort of leaning towards a new device. But I'll try flashing a custom ROM and see what that gets me.

You will need to unlock the bootloader. This can only be done with the app from asus. Then you must install a recovery. I recomend twrp 2.7.1.1 or philz touch recovery. If you want to stay stock flash sbdags's asus stock rooted rom. If you want stock, but with better performance, then flash CROMi-x. If you want the latest version of android and the new zen ui apps, flash CROMBi-kk, then my asus apps 2.0. If you want asus apps, you will have to wait till monday, the current releace has some issues.

.rar file??? Where did you get that from? The Asus firmware downloads as a zip (which contains the zip to be renamed). The ecovery will not flash a rar file...
You need to outline the exact steps you are taking. Somewhere you are making a mistake...

Pardon, I misspoke. I downloaded this zip file: www . asus . com /Tablets_Mobile/ASUS_Transformer_Pad_Infinity_TF700T/HelpDesk_Download/ V10.6.1.14.10 Only for US SKU (Android 4.2.1)
Unzipped the zip within the zip and copied that to the microSD card. Inserted the card into the tablet and nothing happened. Restarted the tablet, nothing happened. Same problems persist.

If you use a microSD you have to rename the zip and boot into recovery.
Rename the ...user_ xxxx.zip to
EP201_768_SDUPDATE.zip
Copy it to the microSD, then boot to recovery with Power and Volume Down buttons and press Volume Up on the flashing RCK icon. That should do it.

Okay, the instructions did not say to rename the file or to boot into recover.
I don't have the tablet with me today, so I will try this when I get home. Thank very much you for your help.

Followed instructions. Got notice that the update was starting, then instantly I get a prostrate android with his chest panel opened, a red triangle with an exclamation point and the word 'Error!' underneath. The device is now completely unresponsive in this condition, reacting only to holding the power button down until the device restarts.

Ok, halfway there.
The recovery sees the zip file but fails to open it. Either because it became corrupted during download/unzip or because it's named incorrectly.
You can just reboot by long pressing power from the dead Android screen btw - no harm done.
Recheck your steps.
You download the Asus firmware (file name contains "UPDATELAUNCHER")
You unzip that file ONCE, resulting in a file name that has "user+firmware version" in it.
You rename that "user" file to EP_201_768_SDUPDATE.zip (caps do matter).
Make sure Windows is showing the file extensions! In Windows Explorer - does it show the file's extension?
Do you have "Document" or "Document.doc", "Picture" or "Picture.jpg"?
If Windows adds file extensions automatically you may have named the file ....SDUPDATE.zip.zip

Okay, windows is not automatically adding the extension (I get the deleted file extension warning if I omit it and try to save with the suggested file name). The file name in the last two posts are different (one with an underscore between the EP and 201 and one without), and I've tried it both ways and I'm getting the same result regardless. And I've downloaded the rom update file fresh from the ASUS website, and I'm still ending up in the same place. Broken Android.
Just to clarify, when I download the original "UPDATELAUNCHER" file, my steps are to unzip that file, extract the zip file within, and rename that to EP_201_768_SDUPDATE.zip. Put that on the microSD card root, insert that into the TF700T, start in recovery (PWR+Vol down), select 'RECK' (I think that's what it reads) and hit Vol up, and it should take care of itself after that. Yes?

Your card is FAT32 formatted?

Okay, I managed to miss the instruction to use the alternate method and so had not formatted the microSD to FAT32.
Formatted to FAT32, re-ran the steps and apparently the update took..... in part. I am no longer getting the same bevvy of 'Unfortunately [Google process] has stopped.' messages as I was before. But when I launch Google Play Store app, the 'Unfortunately...' message appears immediately. None of the other Google apps present this problem, but of course many of the 'problem' apps from a few weeks ago are not on the device by default. And with Play Store constantly crashing, there's no way for them to get on the device.
So the device works.... but no apps can be downloaded or updated.

Okay, I just did another factory reset. Can launch Play Store.... but no apps will update. I get an error saying "Update for [app] could not be downloaded due to an error. (Error retrieving information from server. [RPC:S-7:AEC-7])" A trip to the Google Box indicates that this might be a problem on Google's end, and is account related. Si?

Okay, sorry to be shotgunning the thread..... the error message appears to be account-specific. I've signed in using a different Google account, and everything appears to be fine and dandy when using that account as the primary for the device. I've added the 'problem' account, and it seems to be going smoothly. Just updated something like 40-odd apps without incident.
Thanks for the help!

[Completed] [Q] Smartphone android 4.2.1. Guophone I9600 fully bricked. I you help me, please?

Hello,
I am contacting you to see if someone can help me.
I have a Chinese phone. It is a Guophone i9600, MT6589 CPU quad core 1.2 GHz with 1 GB RAM.
This week it began to continuously display messages “memory full” and it told me to uninstall applications. I looked in settings options and it really showed internal memory was fully occupied ... when it wasn't true. There aren’t no applications installed nor data (including whatsapp app).
I restored the phone to factory defaults and it worked well. Now there was a lot of internal free space. After this, I installed lnk2sd app and I started uninstall applications that came with me smartphone ... but the phone has been bricked.
When I turn it on, it hangs in the original logo GUOPHONE. I don’t have any backup.
My laptop doesn’t recognize it. I have downloaded MT65xx drivers and when I try to connect the smartphone, it tells me not receive reply from the peer (I guess it will be smartphone). Therefore, I can’t use all that solutions that need to connect mi smartphone to my laptop (flash tool, CWM, TWRP, ROM manager ...). I think the only solution is to load a ROM file in ZIP format from the factory recovery menu.
I searched ROMS and I only found one in needrom.com (for Guophone I9602 (I guess you can be the same as mine, i9600)). I've downloaded it from a web page link and a mirror link, and one is a single file with img extension and the other one is a .rar. I have unzipped it and it has a few files with extension tar and img. I've tried everything, zip them, unzip them, renamed file extension... and nothing have worked.
I have also tried to generate a zip with the two img file (I think they're called recovery and boot) as someone said in some websites and it didn’t work. They said I have to include a META_INF folder, but I have no idea where to get it.
I have even located the manufacturer's website, I sent them an e-mail to ask them smartphone`s ROM zip file and they didn’t reply me.
One more thing, I bought two identical phones, one for a friend and one for us. Is there any way to get from me friend’s smartphone a file from ROM ZIP file to use it in our smatphone from recovery menu?
From my friend's phone I have downloaded (in "backup user data" option from original recovery menu) a file with backup extension. But when I try to restore it in me phone, it shows me a checksum error.
Thanks in advance. Excuse my poor English, please.
Best regards.

Hi,
I can't find anything relevant on XDA for your device, so asking here is your best option,
> Android Development and Hacking > Android Q&A, Help & Troubleshooting
Also, I would not attempt to flash anything not designed for your exact make and model number. Or that could be the end of your device.
Good luck!

Thank a lot, Dart.

Need help to reinstall OS/restore APKs [Fire HD 6 but don't need specific Fire info]

So I rooted my old FireHD 6 perfectly using this: https://forum.xda-developers.com/fire-hd/general/how-to-downgrade-to-4-5-3-root-device-t3139351
It was my first time ever trying the do a root and it worked perfectly! I then installed System App Remover (ROOT) to clear some remaining Amazon apps out. It seems I selected some system apps by accident and hit remove. This totally screwed everything up in the OS as expected and I was very annoyed at myself for not double checking my selection. So these deleted apps are sitting in the recycle bin of SAR and I CAN restore them I assume? The only problem is that my tablet does boot up, but you can't select hardly anything and my screen is just a black background flashing when plugged into USB. It accepts commands form ADB, but I need to somehow restore the whole thing or open this app remotely via ADB. There's no options in recovery to reinstall the firmware either.
Can anyone help me with my weird issue? Pretty please?
P.S I'm new so if I have missed any information please say. I have also tried the unbrick floating around via Linux, but it doesn't load on my PC. I don't think it is totally bricked though obviously.
