[Q] Does CWM work across devices of the same model? - Nexus 4 Q&A, Help & Troubleshooting

This may be an obvious and stupid question but I looked everywhere but couldn't find an answer to this.
I have a defective charger (bent at the tip) that keeps falling out of my phone when trying to charge it. The charger has to be OEM because my case is really tight and only fits the OEM ones, which are, shockingly, not on eBay or Amazon.
I never got around to calling Google until now. Today I have discovered that they have a policy that, if I want a replacement charger (free under warranty), I need to send in my phone and start over with a new one, which I think is ridiculous.
I of course have my phone's apps, data, and everything backed up with titanium, but I still prefer Nandroid for obvious reasons. If I get a new phone, would there be a difference in hardware or device ID that would make the CWM backup not work on a new Nexus 4 of the exact same model?
Thanks in advance!
P.S. If they find out the bootloader's unlocked, phone's Cyanofied, blah blah crap, would they bother replacing it? Or would they even look?

[Q] Somewhat dead touchscreen?

So my awesome Venue Pro with an already sketchy battery is giving me trouble.
It has only happened lately. I'll turn on the phone from standby in order to, well, use the phone. But 95% of the time, the screen will within a split second go black, showing nothing on it. Funny thing is, every key works and illuminates and you can even interact with the touchscreen as I noticed it made sounds previously when I just started moving my finger along the screen, same with powering it back on when it likes to actually show what's on the screen and it'll be on a totally different app or screen itself.
Because I bought it on eBay, Dell, very ignorantly, is refusing to even deal with me in regards to warranty despite the phone being manufactured this year, so I'm hooped for sending it in at all for repairs.
If the touchscreen technically "works", then what could be the problem?
Thanks for your help, guys.
You might want to google something like "dell ownership transfer." Seems to me there was a way to transfer the original warranty term to another person. If you can get in contact with your ebay seller, he may be able to help you out.
Short of replacement, I say the first thing you should try is opening it up and making sure all the cables are connected internally.

The next step will either be re-flashing the original stock 7.0.7004 rom in hopes that it's a software problem (unlikely if you ask me,) or ordering another DVP off ebay and swapping parts until you have diagnosed the problem.
That's the issue- My eBay dealer didn't actually buy the phone himself. He took them as a donation for his not-for-profit business so the proof of ownership is pretty much MIA.
I'm starting to believe the backlight is failing or something close to that. Possibly due to the slider being used? Not any more often than someone else would use it, though. I looked at the disassembly guide and it's something nearly impossible with my lack of tools or understanding.
I'm pretty much hooped then?
Wow, shady. I bet he took advantage of and offer like this and then just sold the phone for profit.

I can't think of any other ideas personally. Selling it off for parts seems to me like the best course. If you decide to do this, you should wipe your phone with a soft reset as you normally would when selling this phone (in settings > about > more > reset my phone.) If what you're experiencing is a software problem (which, again, I very much doubt) this might fix it. If not, your personal data is gone, and you're ready to sell it.
You may want to let the other forum members weigh in on this, but I don't think there's going to be an easy fix that doesn't involve disassembly.
I have attempted a reset + restore and whatnot, so most likely it would be a disassembly issue then.
The issue with me taking it apart would be that I'd probably do more damage that way lol.

[Q] Nexus 4 with broken (fullly black) screen and no USB Debugging

Hello xda-developers forum,
I realize this has been asked before, and I've read through many threads here and elsewhere, but I'm not getting a definitive solution that works for this particular situation.
Here are the details:
Phone Model/Make: Google Nexus 4
Carrier: Wind Mobile (Canada)
Screen is cracked/broken, completely black.
USB debugging is not enabled.
Completely stock ROM, have not made any customizations to the phone.
I have adb set up on my laptop, but don't know how to proceed in terms of loading into bootloader (?) and flashing, pulling data, etc.
Mostly only need to retrieve photos and videos. Already synced with Google for contacts (but not photos, unfortunately).
If you need more information, please let me know.
Is there any way I could retrieve the photos or are the precious memories lost forever?
Thanks in advance!
I dont know what cause you that problem.
but i suggest you to install driver on the computer and with tool box install stock rom in your phone.

Installing stock ROM would wipe his device, if he were able to, which he obviously can't.

A new screen should work, as long as that's the only thing that's damaged. It's up to you whether it's worth the $45 for a new screen assembly or $60 for the entire front unit (less frustration and possibility of screwing up than just the screen assembly) to save the photos on your phone. Those are USD amounts - I don't know how that translates into Canadian or if shipping will be extra. Swapping screen assemblies on the Nexus 4 is actually fairly easy - especially if you buy the assembly already installed with the bezel. I've done it myself probably 20+ times trying to get mine to work (I eventually did). There's plenty of teardown guides and videos on youtube on how to do it. Get yourself a new battery while you're at it, for $20. Maybe you've already replaced your phone, but either way you can get practically a new phone for $45-80 depending on what you want to replace, or a cheap back-up (always good to have) for whatever you've replaced it with. Plus all your precious memories back.
You cannot unlock the bootloader without losing everything so your best option to restore important data is to replace the screen. The battery is glued pretty hard to a breakable piece so watch one of the YouTube videos and decide what all you want to replace. Ifixit had a good video that I used when I had to replace the logic board in mine.

IMEI Change - EFS Backup Available

My phone seems to have caught a case of sudden death. There's no response to any hardware buttons, no download mode, nothing. That part I've given up fixing.
Being a smart user(I like to think so), I've got backups of my backups, including my EFS partitions, from TWRP.
I'm going to fix my phone by taking the logic board out of a broken screen phone I buy on eBay, but the seller isn't sure about the ESN status of the phone and hasn't responded to my messages. (seems fishy to me too)
In the event I do buy it and he is a dishonest seller and *illegally* sells me a stolen phone, but disappears off the face of the earth after I buy it so I can't get a refund... His profile has him listed as a top rated seller, but just in case...
Long story short, if I do end up stuck with a bad ESN/IMEI after all this, what would I be able to do to change the IMEI to the old, dead logic board's number? Would it be as simple as reflashing the EFS, or would that cause other problems?
Look guys, I know typically it is illegal to change an IMEI, blah blah, but I've done my research and (in the USA) you can legally do it if you own both devices, and you will never be using the "donor" device again. Seeing as it's broken, it certainly can't be used again.
I've seen some horror stories about data in particular and I can reflash it comfortably, I just need to know if there's any device specific issues with reflashing the EFS like on Samsung devices.

Galaxy s4 almost bricked

Hello. I want to start off and say that even tho i used a lot of phones Samsung fits me bets. With that in mind i want to tell the story of my broken s4 i9505. I bought it new and used it about 2 years until i got and iphone 5s. The phone remaind in a drawer with the intention of selling some time but forgot about it, then i used the phone once a week or so paired with moto 360 because iphone could not connect and used the watch only for time .(bluetooth worked fine remember this). Anyway i decided to sell it and i had all my apps and accounts in there so i thought the fastest way was to factory reset it and make it fresh so i can sell it (rom was not stock at the moment, i have no ideea what rom it was). I sold it to a friend that told me he wanted to pair something with it thru bluetooth and bluetooth didnt work...i sayd that it wasnt possible because all i did was a factory reset and that couldn't damage anything. Things got worse as the phone was charging very very slow and if it got over 90% baterry would not respond to anything (red led at 90% and got to green when full but still no response from phone) and the only thing to do is to remove battery. Then i took the phone back, got it a new battery but that didn't changed anything, took it to some repairs shops that didn't ever hear about this problem, i had it chance the software but that didn't do anything. The problem i suspect it is and i saw a few other posts online was the bluetooth module would stop working for some reason and do this to the phone. Currently i don't know what to do with it and i don't want to sell it just for part for 50 euros or so. Also i read that the bluetooth module can't really be changed as a spare part because it's part of the motherboard and that means almost all the phone. Phone is in mint condition, i didn't damage it before the sell , the buyer didn't damage it or messed with the rom...Another thing i noticed is that in settings under bluetooth address says unavailable. Can someone please help me ? I can provide more information about serials and stuff if needed. Also wi-fi doesn't work now.
Mine also show unavailable under Bluetooth address, but it works.
Are you currently on the stock rom?
Yes is stock. Android version 5.0.1 I9505XXUHOJ2. If i toggle bluetooth on says starting bluetooth then after 5 seconds it disables. I guess the problem is from hardware not software. So fast battery drain is not normal something is using a lot of energy.
As far as I know, the Wi-Fi and Bluetooth modules are in the same physical chip, therefore something might be physically broken. Here's a clip I came across while trying to fix my phone's Wi-Fi and I think it's exactly what might fix yours. (Should be very cheap to do too.) I think basically what he's doing is putting some flux on the board then reflowing it with the hot air gun.
Before taking that step, be sure to exhaust the possible software fixes. I'm not sure, but updating the bootloader and modem MIGHT fix it.
My wi-fi started working again it just took a while but the bluetooth does exactly the same as in the clip so maybe that's the problem. I don't understand why does so glue over it make it work...also for me it's hard to turn the phone off because the screen goes black but the blue led still stays on and the only way to turn it off completly is to take out battery. Maybe this will solve the battery problem aswell ?

Phone charger probably burned my S5 overnight

Hello everyone,
I have a problem with my Samsung Galaxy S5 and I was hoping to find some help here.
When I got up this morning I unplugged my S5 from its charger. However, it was turned off which is usually not the case as I usually don't turn it off. After trying to switch it on for several times and failing with it, I asked Google for help.
What I found after some research was a hint that it might be a problem with either the battery, the charging cable or the mainboard that has been damaged/burned.
Long story short, after some testing (tried a new battery and charging cable) and going to two different repair shops, it turned out it probably is the mainboard. (I'm writing 'probably' because I don't trust those shops 100%. I left my phone at the second shop for about 2.5 hours though, for error diagnostics).
Nevertheless, what I want your help with are these three questions:
1. If there really is a problem with the mainboard, how can I find it all by myself? Is there a way to tell it apart? And is there a way of telling which (more or less) exact part/entity of the mainboard has been damaged?
2. Let's say the mainboard is damaged. Is it possible to fix it? And by fixing I don't mean to just replace the mainboard, but really fixing it. (Ofc I know it might depend on the part that has been damaged, this is why I asked Question #1).
3. Assuming there is no (feasible) way to repair that mainboard. How can I possibly save the data stored on the internal memory? Is there any Software available that can still read the storage? Or do I have to physically move the memory chip to a functioning mainboard, e.g. by soldering?
Any help is appreciated. Thank you in advance!

My personal opinion would be that one or both of the following may have happened.
1) Bad Charger - Chargers can go bad without any warning that resulted in your battery going dead.
2) Bad Battery - Also can just go bad suddenly or over time.
The motherboard of your device has a type of regulator that will only allow a certain amount of voltage/amperage to pass on to the battery. It's extremely rare for a proper charger to kill a motherboard (unless jumper cables were involved LOL!).
Your best bet is to replace both the battery and the charger but, this is only a suggestion/recommendation.
I wish you the best of luck!

Thank you very much. Unfortunately using a new battery and a new charger didn't solve the problem. And my charger is still in use for my backup phone, which is a Samsung Galaxy S2, and it's still working fine.
So it appears it really narrows down to some physical damage on the board.
After some more reading I found out that professional data recovery uses eMMC adapters for their SD card slot, as eMMC is downwards compatible to MMC. Unfortunately those adapters come at a cost of 85-230$, which of course is still cheaper than paying for professional data recovery, yet too expensive for having no actual clue how it even works. I still didn't figure out what the data will look like once I get access to the memory chip. Will I have to use an android emulator to get to the data? Will I have to use some special recovery tool to read the memory? Or is the eMMC already formatted in such a way that Windows can easily read it?
Anyway, what I'll try now is the cheapest method that came to my mind: mounting the eMMC on some sort of USB stick, that I found on aliexpress for 5$+shipping (it's called "USB3.0 eMMC 153 169 U disk PCB NS1081 main controller without flash memory for recycle emmc emcp chips").
I hope this will suffice to read the memory, somehow.
Any comments on this?

Unfortunately Motherboards can go bad suddenly too but, there's a few options.
Option 1) You can try buying a USB JIG from eBay for $3-5, it's a tool designed to force your device into download mode. It isn't guaranteed to work but if it does you can flash the firmware. If it doesn't then you only lose $5.
Option 2) You can see if there's a friendly and helpful individual at an official service center for your device for a JTAG service. Though it isn't guaranteed to work but, some may do it for nothing while others can charge up to $50 +/-. The fees are all individually determined by them. Some have the JTAG service there while others require it to be shipped to another shop to repair them and then ship it back to you.
Option 3) You can always purchase another compatible motherboard and put the new one in your device. This is an option you can do yourself if you're careful.
These options/suggestions are the best that I can think of at this time and I hope one of those will work out for you.
Good Luck!
