Question Development for this device dead? - Samsung Galaxy Tab A7 Lite

I don't see much projects or even a custom recovery coming up soon because the forum for this device is very inactive , Is this device gonna be left behind like the Galaxy A80?

It's an Mediatek device. Don't expect custom roms.

This device sucks I rooted it for experimental purposes bt while removing some bloatware like Netflix using Titanium backup it didn't even got removed stating failed to locate APK then I tried lucky patcher and boom my Device went into bootloop.
My OEM was unlocked that was the only reason I was able to restore this crap.
Damn

[Q&A] [REF] LG Optimus FUEL lgl34c

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!
*ROOT*
These are the instructions I followed to root.

dont forget to install supersu

and busybox afterwards!

*RECOVERY*
Downloaded "TWRP Manager" from play store.
twrp settings, I enabled the sd card patch.
Install twrp\device name :l34c\version i instaled: openrecovery-twrp-2.8.4.0-l34c.img
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.
Sent from my ALCATEL A564C using XDA Free mobile app
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.
Here is link anyway in case anyone is interested:

[Q] Overwhelmed: Pop C1 custom ROM installation

Hiya
I have an Alcatel Onetouch Pop C1 4015D (and for the record, I'm never buying this brand or similar junk again). I just got it un-bricked after a few months thanks to the online USB firmware updater. It's currently in pretty much its factory-default state again, preinstalled crapware and all.
What I'd like to do is install a custom ROM on it, to have a clean system I can actually enjoy owning, e.g. AOSP (if that is what I think it is: the basic, clean Android system). The problem is that I'm getting a little overwhelmed with information, tutorials linking to more tutorials, tutorials linking to downloads for which I have to "complete a survey" and such (abort abort abort), 2 different tutorials for the same thing stating different ADB commands, a few outright scams, etc etc etc. There's tons of information out there, but 90% of it seems wrong, irrelevant, device-specific or otherwise unusable. I've already spent hours on this and still haven't gotten anywhere.
I'd be very grateful if someone actually reliable could walk me through the entire, correct process, please. :fingers-crossed:
I'm just going to write down the bits and pieces of info I already have:
I've already rooted it with Framaroot; no problems there, superuser works.
I've found this site that lists several ROMs, presumably specifically for the C1, including the standard ROM and a cleaned version: tinyurl dot com/o24wqoe. The AOSP one strikes my fancy and is on my SD card already.
The same site says I can just put the provided ROMs on my SD and install them as updates via stock recovery, but I highly doubt that because I read everywhere you specifically can't do that. Sounds like fake advice to me.
I'm told I'd need to unlock my bootloader, but once in fastboot/bootloader mode none of the offered fastboot unlock commands really do anything. The "..." appears in my console and then nothing.
I've tried installing TWRP and CWM recoveries, but you know, "your device is not supported". There's this video of a C1 with a custom recovery (watch?v=_TGgXIp3fWM) and the comments claim it's CTRecovery, but I can't even find anything about that. I already submitted requests for a fix for my device to twrp and cwm half a year ago before I bricked this thing, and one person promised he was gonna make a build for me, but nothing came from any of that.
I think that's just about all the useful things I can extract from this whole mess of information I have...
Please help me make sense of this overload of info and device-specific shenanigans, and walk me through what seems to be such a simple process for everyone with a mainstream device?
For the record, I'm back down to barely being up-to-date on what is what anymore. I'm more than familiar enough with the theoretical side (bootloaders, partitions, bios, etc) because of my heavy computer usage (professional programmer), but once I get into Android I'm just lost. All that fancy terminology nobody seems to bother to explain, things that are taken for granted but aren't really obvious (like a guy demonstrating the installation of a custom ROM, and only mentioning 10 minutes into the excessively long video that you need to install a custom this and custom that first), so many alternative methods for the same thing that have different dependencies (unlocking bootloader vs custom recovery), etc... I don't know anymore what's device-specific and what isn't, who is telling the truth, what a given tutorial is actually making me achieve in the end, etc. TL;DR I'm lost, I'm not stupid but I'm not gonna pretend to know anything about Android's subsystems anymore at this point.
wow u wrote a full post and u speaked for me as have the same problem
Custom recover
i have made a recovery for the 4015x
and got one of the roms to work
(and a fixed stock recovery)
there are 6 versions of this phone and at least two different partition tables that ive seen
but getting it back from softbrick id use the "mobile upgrade s 4.1.1" from the alcatel site
alcatel,mobiles,all mobiles, pop c1, support and on the right hand side down load the program and follow
this forces a stock rom back on the phone (no root and all data wiped)
im waighting on the mods to let me post links so i can host the roms and recoverys
but if you want to mess with the roms your self you can edit the partition tables and get the roms to install.
id use the app "diskinfo" to check what partitions your system and data etc etc are useing and chainge this in the roms.
hope this helped
p.s. if not i could poss look at editing the aosp rom for you and host if for a bit
just waighting on beeing able to post links :s
Alcatel onetouch c1 pop
MY PHONES flash light or led light comes on but it wont come on at all jus remains black wont start ....i tried restoring rom but ,it was useless ,well i used the upgrade tool and there wasnt the right models for my phone what should i do now .oh and also my phone has no stock rom from nowhere on google im so in need of getting back my phone .how can i fix a bricked or whatever phone its a alcatel one touch pop c1 4015a
What is the online USB firmware updater? Mine is also bricked

Do I have right procedure for installing custom recovery from I605VRUFND7?

Please, I hope somebody doesn't start berating me for not reading XDA posts about my Verizon Galaxy Note II more thoroughly. I have read many over recent years and been saved by quite a few during the hacking of my SCH-I605. Furthermore, I've been working in software development and network administration for decades now, so please don't somebody suggest I not mess with rooting my phone, custom recoveries, et cetera. I am here asking questions to make sure I don't hard brick my phone. Not asking resulted, about two months ago, in almost succeeding at Kobol's very interesting "short the tiny resistor" mode of getting out of a boot loop. I have a fully functioning phone now running rooted Kitkat and it's a sturdy platform, runs really great after I melted most of the bloatware and froze the rest (in case I ever need it), but I'd still like to move on to Lollipop and there is only one means for doing so which I know of (CyanogenMod), which I think may be problematic unless I am able to reflash an earlier ROM with unlocked bootloader.
The basic question I need verified is multi-part but basically boils down to this:
1. Is it or is it not true that if one is at baseband version I605VRUFND7, the bootloader is locked and one cannot install a custom recovery? (I think I read that in a few places anyhow.)
2. Is it or is it not possible to flash back to I605VRALJB from rooted I605VRUFND7?
3. Is flashing back to I605VRALJB, then installing TRWP or CWM, then using custom recovery to flash the latest CM12.x the best and only way to get from rooted Kitkat to rooted Lollipop?
4. I know there are some functional improvements in Lollipop but are they really that significant? I like the whole "material" thing which comes with Lollipop, but not at the price of loss of functionality.
Anyhow, here's my little sob story, which has a happy ending -- perhaps some of these details will elucidate my situation and lead to better answers:
I got tired of waiting around for Lollipop and had been unrooted by Kitkat for almost a year when I rooted again back in July 2015. I had wanted to go with the latest CyanogenMod Lollipop version, but ran into problems first using Heimdall (which refused to properly connect and write) and then trying Odin (against best advice post-root) to install a custom recovery (preferred TWRP but would go with CWM). Always led to that "unauthorized software" boot screen, which then necessitated reinstalling stock Kitkat and rerooting (I found the Ghettoroot .BAT file worked okay.) All was well, I was too busy to think about Lollipop but I woke up one morning about a month after I rooted Kitkat to find my Note II was stuck on red Verizon book splash-screen. Found a great article and YouTube showing all the keypress sequences which might exit a Note II from been stuck in boot -- but unfortunately not until after my further finagling just left me with a dead no-display-at-all device. I undertook Kobol's method, which requires partially reassembling the Note II's electronics outside its case and attempt to reboot with a very tiny screwdriver shorting a minute resistor on the motherboard right adjacent to the CPU -- I did in fact see the screen flash on briefly -- but I held my little screwdriver down too hard, accidentally gouged out the tiny resistor, and ended up buying a refurbished motherboard which very likely may have been scavenged from a stolen phone before going on sale on eBay. New motherboard worked great, I erased the original owner's info and data and proceeded to reinstall and root Kitkat. (Motherboard was already at I605VRUFND7) when I received it.
Anyhow, I also tried to install a custom recovery after I had new motherboard and rooted Kitkat. Using the TWRP Manager app put me back on the "unauthorized software" boot failure screen from Verizon, but I was able to Odin back Kitkat easily enough without losing my apps and configuration data. I believe I tried to use ROM Manager and Flashify as well -- but didn't find those apps very cooperative (though I didn't bother to upgrade to "pro" level on any of these in cast that matters). Unless I am mistaken, all these apps just place a zipped update file in the root of my internal SD card and then just hand it over to the Note II's stock recovery. I figured I just needed to stop and regroup later. That was a few weeks now.
Honestly, after the ordeal of having to replace a broken motherboard, and also -- after having looked at Verizon, Sprint and AT&T and the new Galaxy devices with no removable back and cracking the phone open necessary to replace the battery or upgrade the hidden microSD card and not liking that one would have to pay $600 over two years for a smartphone even further crippled at the cell carriers' requests -- it's even more important to me to be careful not to damage my Note II. (In fact, my Note II had turned out to be irreparable, I might even have even bought a refurbished unlocked Note 2 or 3 or 4 -- Samsung has made a real error on their latest generation of phones with their sealed backs and no user-accessible microSD reader.)
Yet, perhaps naively, I really do want to move on to Lollipop and even Marshmallow when CyanogenMod makes that available. So I really would appreciate it if you guys can verify whether what I intend to do (downgrading to pre-Kitkat in order to install custom recovery and then CM12.x) is workable? Or if there's a better solution? Or if I should just be content to have Kitkat rooted with all the fat cut off?
Many thanks. Hope my digression was not too long. Please don't anybody yell at me. XDA Developer's web forum is so full of very useful write-ups but unfortunately also some incorrect information and a lot of just plain useless posts -- it's really difficult sometimes to tell posts by guys who are actually experts from post by well-meaning folks with a lot of ideas but not so much expertise specific to SCH-I605 and VRUFND7. And I really need to get this right. (Granted that nobody on the forum can be held culpable should on mess up my phone based on their advice.)
Thanks once again!

Samsung Galaxy J5 wont install custom bootloader, feel like ive tried everything?

Hi guys. Sorry if this is in the wrong section. I have rooted several phones a few years back such as HTC's etc. However i have been running into a problem with the J5. I believe I have installed the samsung drivers, i have rooted the phone on the software itself via kingroot, however when I try to run ODIN it detects the phone COM/USB port however when I try to flash any of the recovery files it looks as if its going to start to do it then says 'FAIL' and when I look at the phone nothing happens (when its in blue recovery mode) it just says Custom Binary (Recovery) Blocked by FRP Lock - I have tried to search this on the forums but cant find many solutions for it with regards to the J5 - Does anyone have any suggestions? I dont mind the phone and would like to install custom kernel on it to allow for slight overclocks etc as its quite a nice bang for buck phone. but I have spent hours and can't seem to find a solution. There was one post that seemed to suggest if you downloaded a 'CROM Services' APK whilst in android and run that it might work, however this is a new J5 on the latest android and the CROM Services APK file in that link doesnt seem to want to run when i install + try to run it on this android
Any suggestions are welcome! Really wrecking my head over this one
FRP lock means that you have to enable OEM Unlocking in Developer options and/or remove the Google account. FRP is Factory Reset Protection, introduced with Android 5.1.1. Prevents someone from just grabbing your device and wiping it and using it easily. Also, you need to be in Download Mode, not recovery to flash custom kernels and recoveries. You aren't wanting to or trying to install a custom bootloader. That is a whole nother thing.
Thanks for the info! That one option has solved it for me! I will go from here and see how it goes. Thanks alot!

Ulefone Power 2 TWRP bootloop, cant flash ROM

Hey guys, this is my first Thread in xdadevelopers
I am pretty new to coding and all this "behind the UI" stuff, but i am eager to learn more, since its really fun.
So i have got a new Phone : the ulefone power 2 with MTK6750T Prozessor. It has quite the battery with 6000mah, but i still wanted to root the device to archieve like one week battery time or so xD
I rooted, installed TWRP recovery and some apps, everything just went fine. I didnt install a custom rom, since i didnt find any for this phone. Well, i wont buy mtk phones anymore, since they dont offer open source code with all its community possibilities
Anyway, today the touchscreen suddenly stopped working. I thought its a common bug, restarted it. Now it wont start the OS anymore, its only booting in TWRP. I dont remember well, but it said something like "phone is not safe, gotta factory reset".
Since i have TWRP, i just did the reset. Without success though. Its still booting into recovery and cant shut down either, whatever i chose in TWRP options.
My next thought was flashing a new ROM with TWRP, which doesnt work due to "zip file is corrupt" error, even though its the stock file from ulefone.com
Since TWRP has a command terminal, it might be possible to use to stop the recovery bootloop when connecting to pc? in this case i might be able to use adb, but atm i cant, and the battery is non removable
I dont care that much about having a phone, i could just buy a new one (xiaomi redmi note 4x it would be), but i would really like to fix this and enlarge my knowledge for situations to come.
Hopefully someone of the professionals here can help. There is a similar Thread already by drkeey, but in my case i can still use TWRP with my mouse, so there might be hope.
