Hello,
just bougth a low-cost and really little android phone: Alcatel OT-980. It's quite cheap as long I bought for 79 gpb from new. And it has quite nice specs:
-CPU 600mhz
-256 Rom / 192 Ram
-Android 2.1
-Slide-out QWERTY keyboard
Anyone is working on it? Is it possibile to have root access? What about a new page on XDA for it?
Let's start talking about it guys
So guys no one is interested in it?
I just purchased one of these things and it has a strange fault - the "hang-up" button seems to be constantly depressed so it's always trying to shut itself down. If I hold that button down it goes back to normal, it's like the button logic is in reverse or something.
Has anyone heard of this? It's nearly impossible to get Alcatel support in Australia.
Same one was just released on WIND Mobile in Canada.
Cool
Are you planning to buy one?
Nope, I have all the Androids I need for now.

I have the OT-981a (Wind version)
It's just another simple android phone.
Alcatel made some changes to the OS.
Took out the update feature (Probably because they will never support updates)
No live wall papers even though the software is installed.
It is running 2.1 update 1
The usual start up to get to programing mode
(Volume down + power) only restores the phone.
Think it would be pretty damn hard to make a rom for this.
Plus not a popular device so don't hold your breath as much as I would love to find a rom to work on this it is not likely.
Note universal androot does work but the NAT Filter is missing so no Wifi tethering ether

- Is there a bootloader mode in addition to this "recovery" mode?
- If it's rootable, and the bootloader is not locked, there is still some chance a custom recovery could be installed. The question is how many devs care to make a recovery and ROM specifically for this phone.
That is exactly my point no one would take the time for this device.
I tried to the usual bootloader sequence but just reset my phone.
Unless it needs the usb plugged in
What if there's another combo that involves booting up while holding one or two of the hard keys?

Hard Reset
Anyone know if there is a button combination for a hard reset?
Customer downloaded a brightness app on market and the "0" setting forced his screen to go black. Phone still runs in the background but you don't know where/what you're doing.
Help?

Upthread it is reported that power + volume up results in some sort of factory reset. I wouldn't know because I don't have the phone.
Here is an alternate idea, but you'll need someone's help to tell you roughly where to tap on the screen or how many up-down strokes it will take.
- Unlock the phone (swipe, you'll feel the vibration)
- Press Home a few times so you're on your main homescreen.
- Is the Power Widget on one of your homescreens? If so, some hunting and pecking can probably get you to tap on the Brightness icon.
- If not, you may be able to long-press and add a widget blindly, and hopefully that widget will be the Power Widget.

Volume Down + Power is hard reset to factory defaults.
It's what the usual recovery combo is on most android phones lol
backup / fs image
I've done a bit of hacking on my phone, got root, and used the adb shell to install busybox etc.
I'm trying to find a way to get a proper image out of the phone, I'm guessing that I can statically compile dd for it, and create dd images of the different partitions of the nand, on the SD, then loop mount them on a linux machine for development.
If there's an easier way, then I'd like to know about it
Based on that I imagine it would be possible to add in some of the changes that the G1 recovery images have for our phone.
Which version of busybox did you install?
Im going to try and catch up here lol
Is there any way to get the stock rom anywhere, or can anyone get them from the phone?
Ok I have found busybox as well as installed it,
I also sent an email asking if we could get support for the ot-981 from clockworkmods (Rom Manager) fingers crossed here.
That way we can a back up of the original rom
I'm trying to get the image off, dd doesn't work because the mtd block devices can't be read (perhaps because they are mounted, but I would still expect dd as root to be able to read them), and tar doesn't help much, because the tar function in busybox doesn't interpret the --exclude or -X parameters to exclude the sdcard dir (to avoid a recursive tar), and to exclude /proc and /dev and /sys.
I'm going to try to cross compile tar for android and hope to get a backup out that way.
Hi guys new to the scene and planning to get this phone as a low budget andriod device.. I hope you guys will be able to find a way to develop for this phone and more importantly upgrade it. It would be a big help! Thanks for all your hard work so far!!!
So my girlfriend's Verizon Galaxy S III is in quite the jam. The power button stopped working. She has to use a software button to turn the screen off and the home key to turn it back on.
Verizon sent over a replacement, but she needs to send the original phone in. Problem is, the normal methods for returning to stock all involve Odin, which requires the phone to enter Download mode....which we can't do. The phone won't register the power button being held down. I don't even want to turn it off since I'm not sure it could be turned back on.
So I've been googling around for another way (already having used Triangle Away) and found a couple of sets of instructions (here and here) on using Odin Mobile to flash the phone back to stock. But there seem to be a lot of comments around, especially on the YouTube video guides, of people saying it bricked their phone.
What's the safest bet here? As far as I can tell these are the options:
-Shut down the phone and pray the power button somehow works for getting into download mode (doubtful) so I can use Odin.
-Restore a nandroid / flash a zip of the stock ROM and then use EZ Root or whatever to unroot the phone and hope Verizon doesn't look into it.
-Use one of these sets of instructions for Mobile Odin...though it's not clear which one is best and what files I should be using.
-Just send it in and pray.
Odin Mobile seems like the smartest option...but the instructions out there aren't as comprehensive and up to date as I'd like. I'd rather not brick the phone.
Can anyone help? The phone is currently on AOKP 4.2 Milestone.

wrong section buddy. this is international gs3 forum! here's where you have to go : http://forum.xda-developers.com/forumdisplay.php?f=1708
Answer has nothing to do with phone model.
Mobile Odin is the best option you have. I've never used it for a whole Rom. Install mobile Odin + its kernel flash add on (specific for phone model, it's well guided) then I guess you download a whole Sammy Rom in tar format.
Then in mobile Odin use Open File option file in menu.
I guess there must be some guides to confirm that.
Thanks for the response! Didn't realize I was in the wrong section. I'll post over there to see if people have recommendations for which files I use.
you can reboot into download via adb.
it's something like "reboot bootloader", use search.
Mind you I temporary bricked them, but I've yet to this day tried rooting a phone, and never had things go smoothly.
Any guide I try to follow just so happens to be the wrong one, or isn't thorough enough in its directions... Theres always some missing software, or missing details on what to do when you hit a road block, so here is my story so someone can point me in the right direction...
I bought this LG Optimus G LS970 on eBay, and apparently it was already rooted, and it had some sprint apps on it so I guess its the sprint version of the phone. Anyways I notice there are some photos on the phone, so start plugging in the the phone to my pc only to find that i cant access files.... I google some questions, start holding buttons trying to get into whatever boot or recovery mode or some mode i dont understand.
Turns out I got something called Team Win Recovery Project v2.6.0.0 flashed on my phone.... I don't quite get what all these options are, but all I see are wipe options and I'm thinking "Hey this will get me back to factory settings and maybe i can flash a barebones android jellybean whatever (I dont know what os is called on a phone) So I start checking boxes and wiping things...
I soon find out that my device is telling me I don't have an OS. Of ****ing course it doesn't. I realized I just deleted it, because it told me I deleted it.
Well atleast I still have this recovery dohicky so not all is lost.
I start reading unbick guides, and of course I dont know what they mean, I just download every link they tell me to and run them. I install "drivers" and even then, when I plug the phone into my PC, I still get "Did not install" popups even if "LGUnitedMobileDriver_S4981MAN38AP22_ML_WHQL_Ver_3.8.1" said it installed correctly....
I open up this Original LG Firmware thing, and asks for my phone's model and serial number... Just what the hell is my phone's model? eBay listing said E973, the back of the phone says LS970, that useless mobile tool that wont let me download additional drivers says its called LG-LS970, and google results call it LGLS970....
And of course I don't know my phones serial or whatever a "imeieieie" is because I don't have an os to tell me that (guides don't tell me how to get this on a bricked phone and google result is useless)...
So I cand download this thing called a kdz because #1 it wont let me, and #2, and google just doesnt have a download link for it.
All I wanted was a rooted lg optimus g with a nexus-like experience on it without bloatware, and I somehow manage to brick my device within minutes of owning it, what do you think I should do.
I did hold down Vol - to get into some black screen that says "SERIAL" with a number, but that number doesnt seem to work with that lg firmware downloader thing. What do?
Super easy fix. Get an external sd card. Put a ROM on it. I recommend one of these http://forum.xda-developers.com/showthread.php?t=2067871 the latest version is Stock Jellybean of our phones. OR is you want CM10 use this http://forum.xda-developers.com/showthread.php?t=2411406 . Be sure to download ROM+GAPPS for CM10. I recommend those since you probably don't know if your phone has the updated partitions.
Anyway put whichever you want on the External SD card. Reboot back into recovery TWRP (Team Win Recovery). Wipe Data/Cache/Dalvik. Go back then Install the files you put on the External SD card.
Ls970 is sprint version. Only att version has external SD.

Oh wow I read that some many times and it just didn't click. Well it's much hard now. To OP, you should ask in your designated forum. This one is for the AT&T model. The easiest way is to find out how they restore their phones to stock. Probable LGNPST or something similar. Or install ADB, then push a ROM file to the internal, then flash in recovery. You're gonna have to do some research. But it's still easily do-able. As for the issues with the drivers, someone over there should have a link to alternative ones. But you can google "universal ADB drivers" and those should work.
I used LGNPST with a positive result. The hardest ****ing part was finding whatever-necessary file I was supposed to flash to the device. It took me hours to find it (not much help from XDA) and I was never clear if the file I washed, was indeed the stock rom the device came with.
The device now has startup and shutdown animation and jingles I wasn't familiar with (Different from what I got the phone with)
What I know is, the ebay Listing was for a E973 from West Virginia with abunch of Sprint apps on it.
But E973 is said to be a Canadian model? But Canada doesnt have sprint? And the phone says LS970?
I don't know whats this phones origins are, I just know I flashed a file called LS970ZV7_02.SV7_02.P25006.tot which told me to rename to bin, it flashed an outdated, possibly mismatched version of android, and from update to update I eventually got back to 4.1.2 but had new animation startup stuff...
My phone came pre-rooted and pre-recovery, but this recent flash killed those and now im looking to get back to that point. I'm unaware if my radios or whatever are jacked up or not because I never intended to use the device with a service as I get by just fine on Wifi only.
I found something called GAIO but the original page is offline and i cant download it.

Well, by your own admission, you said you needed to flash the LS970 tot file, which wouldn't be in this forum, the AT&T LG Optimus G is the E970, it's distinct in that the back glass has the AT&T logo, for one. On the bottom center on the back glass it also says "LG-E970"
On the left side of the device, with the volume buttons, below them is a tab that pops open for the micro SDCARD and SIM card.
If the phone you hold in your hands doesn't have these distinctions, and you start flashing stuff from THIS forum and not the LS970 (aka Sprint LG Optimus G) You very well might brick, temporary or not, all over again.
That being said, with the correct kernel, MANY of our roms work just fine for your phone, but research and reading is a prerequisite for such.

Welcome to the mobile world, where everyone does whatever the **** they want when developing a phone, and people in their free time struggle to fix it!
I picked up this device from walmart for $29.99 with the intentions of learning some new development stuff.I
thought for 30 bucks there's gonna be a lot of these little "duallies" running around why not a cheap candidate?
So far as i can tell there is little info found about this device so I'm looking to collect what little is known about
it in one place in hopes to get a jump on it. First things first, I am responsible for my own actions as you are yours.
If your not sure ask or simply dont do, some of this stuff can brick your device!

click install... wait... things will pop up..... things will go away... wait some more...
finally a dialogue that states sucess.
***ISSUES HAVE BEEN REPORTED OF LOSING RECOVERY OR THE ABILITY TO ENTER IT AFTER
A WIPE AS WELL AS PROBLEMS BACKING UP AND OR RESTORING.
I have "injected" twrp manager into the system using titanium backup (link2sd will work also). This seems to
prevent any issues I have read about previously mentioned. Also I have successfully preformed backups as
well as restores, both before and after wiping. I have not figured out how to enter twrp recovery upon boot
yet, so be careful of what you do!
*SAFE TO REMOVE APPS*
yet to come
I use "titanium backup" from the play store, still trimming.I can get it down to about 230MB
available "free" ram at the moment but not consistently.
Ok had an issue with a task manager improperly reporting free available ram... true availability was
around 150mb free. There are apps that have to be replaced when removed, for example a launcher
for a launcher but some do not. Again I'm still trimming and experimenting, right now my system rom
around 244mb free. Most every thing I have done has been on the phone its self without the need of a P.C.
*STOCK BACK UP*
Yet to come
Any candidates for a true stock rom? Ive hacked the crap out of this one so far without the need of a back up... i know tisk tisk tisk!
I'm going for a debloated deodexed stock rom, hopefully!
*DRIVERS*
The only ones I could find that actually work. The Verizon drivers mentioned for the g2, not surprising since it runs on vz towers!

I've got a few of these that are bootlooping. They show the LG logo, and then TracPhone Wireless splash screen infinitely in a loop.
Two questions.
1 - Is there any way to recover them? I'm hoping for some sort of a dev tool that I could flash a stock image or something (like Odin is for Samsung phones)
2- When these phones started bootlooping, I installed TWRP on the other Fuels that I have, thinking that I didn't want it to happen to them. My understanding of the TWRP that's installed from TWRP manager doesn't flash a modified boot image, so you can't enter TWRP from a powered off (or in my case, bootlooping) phone. Is that correct? I flashed a custom boot image from elsewhere that allows me to tap vol up at the LG logo to boot to TWRP. Any idea if this is enough of a safeguard to in the even of similar boot loops?
Any chance you know how to get it in diag mode? I need to connect it to DFS but can't without diag. Thanks for your help!

My apologies for the delayed response. I have a lot going on in life.
As for recovering them, use the device you have closest to stock to make a backup. Do this before you attach your account or put any thing in to it after a "fresh wipe". To the best of my knowledge there isnt a tool like odin available, i could be wrong though. You can push a back up to the looping devices via adb. in order to do this you must have previously enabled usb debugging. The instructions are available on the web, i my self dont know how to do this. If you can establish an adb connection im sure you can command it to boot into twrp. For setup and testing use one of the devices that doesnt have a problem to establish adb. There is a little info on another thread i created about investigating the boot process the link is in my signature for the defy. Please be patient with me as i have two jobs and a single father, im not a hacker or developer. just a normal guy that is fascinated by my little robot willing to learn any thing. now that I know this thread is becoming active Ill monitor a little closer. Also if there is any thing i can help with ill be glad to do so. Im wanting to get a second fuel just for dev and learning purposes.
Recovery
Is there a way to access recovery on the lg fuel? I am stuck in a boot loop because I disabled the home screen service as well as other things that I did not pay attention to. I do not have a custom recovery installed.
I've never been able to boot to recovery by way of button press. Seems like there's a way to get into boot loader mode though. Just can't remember off the top of my head, I'm at work now and don't have the fuel with me. I'll see what I can figure out in a few hours when I get home. In the mean time you can try button combos upon boot to include the home button. If we can get ADB talking to it there's a chance I can send you copies of the files needed. Give me more details of what you have done just before the boot looping.

I bought the optimus fuel a few months ago and i've been using it primarily for a music player/run keeping devices during my jogs. I turned off mobile data and i've noticed that i still see signal bars on the top notification area - does this mean that the radios are still on?
I was wondering if there was some way to completely disable the cellular radios so that i could conserve battery life inbetween days where I don't run?
Thanks!
This is a pretty cool app....

Airplane mode and then turn WiFi back on does the trick. "Radios off" = ton more juice
Has anyone found out anything else for this little phone? I have the LG Optimus Fuel. Had it for a few months now. I rooted it as soon as I got it and uninstalled a few system apps like the LG keyboard, the default SMS app and Chrome along with 2 or 3 other Google apps. It's still running fine.
I installed TWRP recovery and a custom boot image so I could boot into recovery by pressing the up volume button. Works great. I made a full system backup and saved it to my external SD card and saved it to my Debian laptop.
Right now I'm just looking for a custom ROM for this little phone but can't find one. I'd love to get Cyanogenmod on this phone but there are none. I'd port it myself but I'm not able to at the moment.

I'll expand on the above link because no one can view all of the info in that thread w/o registering for that site [PITA].
Load towelroot (www.towelroot.com). Upon running towelroot, press "welcome to towelroot v3" 3-times (quickly). Change 1337 0 1 0 4 0 to 1337 0 0 0 4 0 (change only the ONE to a ZERO), click "make it ra1n" and you're rooted. :good:
This was verified on an L34C running Android 4.4, Kernel 3.4.0+, build KRT16S.L34CV10c, Sw ver L34CV10c.
YMMV; IANAL
My apologies for the inconvenience, I was unaware for the need to register.
What I would like to do with the L34C is find a ROM with all the phone functionality removed, and few to no Google Apps (let me just add the ones I need). I am not planning on using it as a phone (I still have my old Casio flip-phone, need nothing else). My intention was to experiment with creating a PalmPDA "replacement", something small to carry around for addresses, notes/memos, calendar (you know, the stuff you used to do on PalmOS), and in addition figure out how to do record-level synchronization **locally** (as in I don't need to send my data to some dirt-floor shack in Bangalore just to have it sent back to a device 2 feet away from my computer). Additionally, would line to use it as a basic portable media player. Essentially, trying to re-create the Palm LifeDrive on Android.
To my knowledge there are no roms available for this device. Your best bet in my opinion is to remove apps 1 by 1 after rooting. Google each and find out what the risk and severity of removing them are. I have donated my device to a less fortunate fellow employee. So as of now I'm unable to help with testing. This method is what I do for all of my devices until I'm finally happy with its performance and functionality. Think of Android as the swiss army knife of the computer world, you can do just about any thing with it, you just gotta figure out what tools are useful to you and the ones you can do with out, then you gotta ask Google witch ones Android can function with out. I hope you find what your looking for in the little robot, its a really neat world inside there!
I hate to bump an old thread but, I also don't it necessary to start a new one, at least not yet anyway but, I too am looking for a way to flash stock ROM. I have LG34Cs to use as a reference..
Where is the link to exposed framework at for this phone?

Broken as in doesn't boot into recovery. The phone will still boot into android, assuming you have a working system, and within android with root you can flash a working recovery image over a broken flash with the dd command on the twrp device info page (twrp.me/lg/lgoptimusfuel.html). So no real risk of brick, just possible inconvenience that might require a battery pull.
I built twrp 3.2.1 with same sources but I have not tested it since my battery seems to have completely died and the phone won't boot with usb power alone.

Hey guys, please forgive me for any bad etiquette or lack of information (any information I can provide is available upon request if I leave anything out). I am new to forums in general and especially to XDA, which seems like a good place to get help.
I recently purchased a Sony Xperia Z2 Tablet from Craigslist under the assumption it was a fully unlocked tablet not associated to a carrier. Turns out it was a Verizon Z2 tablet. I dislike Verizon with a firey passion and without getting into too many details, I'm fairly certain they won't help me because a) this tablet wasn't purchased through them as a customer and b) Verizon and I have bad history (unauthorized account modification, shady charges, etc.)
So I thought I'd do my best to make the tablet mine since the asshole who sold it to me has ceased all contact and I don't know how to get a hold of him anymore. No receipt and a data-less tablet.
Anyway, I successfully rooted the tablet and began installing apps that I installed for my G4 when I rooted it (SuperSU, Adaway, Greenify, etc.)
Things were going well but I realised I wanted anything that had to do with Verizon removed from the tablet so I was going to flash Cyanogenmod onto it with a guide I found online. Now rooting and installing custom recoveries was familiar territory and I did these flawlessly. It had TWRP and I made a backup of the system -no Nandroid, sadly-and I began the flashing process. The process said it completed without issue and I went to reboot my device. Enter my current situation:
The device, when I attempted to turn it on, all it did was vibrate constantly until I let go of the power button. Attempting to enter recovery mode (green LED, power + vol down) it showed me, instead of TWRP, a very basic recovery mode with basic options. "Continue booting up", "enter safe mode", "system recovery", and "power down". I tried entering safe mode and it just shut back down, I tried doing a system recovery and it shut down. The only time I ever see the "SONY" logo is if I'm entering this mode. I can enter what I assume is "fastboot mode" (power + vol up and plugging the device into a PC). Nothing on the screen but the LED is blue. I am trying to find guides to restore it if I can and it all looks promising but the only things I know how to really do are root and install custom recovery. I know there are PC tools I can use to send commands to it while it's in fastboot, or send commands in general I just don't know where to begin.
Does anyone know how to fix this? I know it was from Verizon, which sucks, and I know the problem most likely occurred with the attempted flashing of Cyanogenmod. I think I read somewhere I might have done something regarding mismatching kernal numbers. I couldn't find a way to unlock the bootloader so I assume that had something to do with it too.
If someone could give me a guide to restore it to at least its stock ROM where I can begin rooting and installing a custom recovery again, that would be great. Even better would be just flashing a ROM on there that doesn't need Verizon or being able to take it to a stage where it's unlocked and the only evidence it was ever with a carrier is the Verizon logo on the back. I'd really hate to think I wasted money on this and now I'm at a dead end because of a mistake I made. This was supposed to be a gift for my mom on her birthday which is coming up soon. So if anyone knows anything, or has a guide where we can at least get the thing bootable again and I'll just try and deal with a rooted locked device, that would be great.
Thanks for considerations,

I have spent time on that screen too.
2 things
1. .. If you installed dual recovery, there is an up, down sequence to select the recovery.
2. Find a downgrade guide, use flashtool to flash. Ft back to stock.
Also you need to know what hardware you are running..511, 561.. And use the proper version.
There are some options with the flashtool and prf maker that can remove branding and vendor stuff. I have not tried those options.

Sorry if this is late... But where can I find the stock? I've searched everywhere and I would need to do it from a flash tool on my PC? I could use all the help I can get.
I just had a very similar experience to the OP, seemingly identical in every way, and am curious if anyone has a solution.
ADB won't function at all, and the bootloader has blocked any sort of flashing via fastboot. Can't boot into TWRP, it goes into a very minimal "recovery," which I imagine is the stock tool, and the Factory Restore option there does absolutely nothing. Flashtool would work great if ADB / Flashmode was at all functional (device blinks and vibrates in a fashion typical of something bricked, and no connection is picked up).
Verizon Z2 Tablets are 561s.
This thing dead or is there some way to push back onto it?
