[Galaxy Tab S2 Q&A, Help & Troubleshooting] Extarys:
Hi there,

Now, this issue may already been addressed but if so, I couldn't find it.

I have a T810 tablet and I was running the stock ROM. Last year I flashed a custom ROM and so I thought when I entered recovery mode I was using some kind of custom recovery tool. But I was using the system one.

I formatted everything before attempting to flash LineageOS 'Apply update from SD card', resulting in the following output:

-- Install /sdcard/lineageos-16.0-20190407-nightly-gts210vewifi-signed.zip --
Finding update package
Opening update package
Verifying update package
E:failed to verify whole-file signature
Installation aborted

Now, obviously, when I try to turn the tablet on, I'm redirected to the recovery tool because there is no OS installed.

Also, I suppose this tool isn't meant for any type of zip file and I need a specific one.

Can someone point out to me where I can download the appropriate file?

I tried for the brief moment I could make ADB work flashing a ROM but it resulted in a similar issue.

Thanks for your help!

EDIT:

I tried flashing 'T810XXU2CPD9_T810XAC2CPE2_HOME.tar.md5': E:failed to map file

Everything I flash with adb result in footer or signature error.

I would really love an insight on how I can fix my tablet now that I f-'ed up everything.

I'm sorry for bumping this but I'm still trying to figure out how to unbrick my device. If you have anything for me, please tell me. I don't want to lose my tablet.
[Galaxy Tab S2 Q&A, Help & Troubleshooting] viasat:
Can you enter download mode after reboot?

If you can,you can flash an official rom with Odin.

Cheers

So, I have the KURATU [K8432] head unit, https://www.amazon.com/gp/aw/d/B07HQHCH65?ref=ppx_pt2_mob_b_prod_image. Is there anything cool people can tell me about it :). The seller says it rootable, etc, but who knows. Is it? Twrp, Magisk, other roms, etc. Or am I stuck with stock?

Also, first time with an android system like this (or any, basic radios before). Any tips/tricks to be aware of?
[Google Pixel 3 Questions & Answers] bobby janow:
Has anyone had the screen flash and updated to dp2 and then it was gone? I'm on the April update and the phone just went nuts. Had to turn it off let it flash for like 10 min then it went away for now. Oops it just came back. Unusable

edit: After a night's rest it seems back to normal. What happened was I was minding my own business, reading some forums, news, etc. before bed. Swiped left and I saw a flash. Hmm.. interesting, right? Then all of a sudden the bottom of the screen started flashing and then the whole phone. And I mean multiple flashes / second and very bright. I even saw the light when I closed my eyes later it was that bright and steady. So I turned off AOD, no help. Rebooted, no help. Turned the phone off for a few minutes and it came right back on restart. Put the phone on my night table face down and watched the light show for a while illuminating the room from out the sides of the phone. Then it stopped. Woke up and it seems to be gone at least for a while. I'll call G for a replacement this morning but seriously! This device is simply flawed. Obviously April update did nothing corrective for this phone. I wonder what happened with the displays on these phones since the XL doesn't have this issue. I might just see if they'll comp me an XL upgrade even though it's really too large for my tastes. Anyway, that's my story for the day.

I'm curious, as asked above, if anyone with a similar situation has joined Q beta and the issue is resolved. It's hard to determine I get that due to the intermittent nature of the flaw but I would install DP2 if it indeed fixed it. TIA
[Google Pixel 3 Questions & Answers] GoreD:
I’ve got the exact same problem/question....
[Google Pixel 3 Questions & Answers] bobby janow:
I installed Q and it did nothing. Still went buggy so I returned the device. Bought a new one which has been ok for about 4 days so far. I'm not holding out much hope since many have experienced the flashing a few days after the return window closes, I think it's 15 days. The only solution so far is to either get an XL with a different display or an iPhone XS for $1000. Google is not acknowledging the design flaw as of yet.
[Google Pixel 3 Questions & Answers] qualitymove13:
I used to get it regularly (a few x a week) on Pie but havent gotten it since the first Q Beta.
[Google Pixel 3 Questions & Answers] decker39:
Just ordered this phone on a new contract, wondering if i've made a big mistake. This screen flashing saga seems quite widespread ?
[Google Pixel 3 Questions & Answers] bobby janow:
It is widespread but not guaranteed to flash. My wife has one bought in November and not once did it flash. I'm on my 4th new one now. The problem now is that it doesn't happen right away so you're kind of behind the 8 ball. When it does happen it's usually after about 3 weeks at which point there is nothing you can do about it other than get a refurb replacement that someone else has sent back due to flashing. I really don't know what I would do if I had to pay full price. Just curious, what did you pay on a new contract? If this one starts flashing after my return window I'm trading it in or getting a refurb and selling it unopened. If I can get $500 I'd splurge for the extra 5 and get an XS. The 3XL is just too big for me as is the XR. I want something 5.8 or smaller. I mean it's a great device if it just didn't flash. The fact that it flashes in safe mode and through the entire reboot pretty much says this is not a software bug but hardware. Read it and weep... https://issuetracker.google.com/issues/119210591
[Google Pixel 3 Questions & Answers] decker39:
£20 upfront cost for the phone then £26 a month on a 2 year contract. After reading multiple stories regarding the flashing issue, seems the majority of users are having problems after AOD is turned on. That link leads to depressing reading ?
[Google Pixel 3 Questions & Answers] bobby janow:
Pretty much the current US prices, not bad. Yes, AOD caused it initially but as I said, my wife has had it on since day one and never a flash. Turning off AOD or perhaps never turning it on might help but that is really not the issue. Why can't you turn it on without a blinding flash searing your eyeballs? I like having it on, flip the phone over to disable it and not much extra battery use. I wish you luck on yours. As I said the phone is great, quick, good size, decent battery life and great camera. The google issue tracker is indeed depressing to read but those are the facts on the ground. I think at some point they will have to address the issue and perhaps we will get a great trade in for the Pixel 4. We shall see.
[Google Pixel 3 Questions & Answers] bobby janow:
The pixel 3 xl is now on sale. Might be time to pull the trigger on it if you can. No flashing on that device. 200 off retail.
[Google Pixel 3 Questions & Answers] decker39:
Pixel xl is too big for my liking, but thanks for the thought. Mine should be with me tomorrow, so i'll turn AOD on and see if it causes any issues, if does, it's going straight back and the contract cancelled, i have 30 days to do this. Or.........save causing me any headaches, send it straight back, cancel the contract and go for something else.... Galaxy S10e ??
[Google Pixel 3 Questions & Answers] bobby janow:
I have Google Fi on one of my lines and they have a 1/2 price sale today only on all Pixel 3s. So I went over to Best Buy to check out the size of the 3XL and it's not horrible. A little too big for my preference but it doesn't flash and I won't have to return it. So I'm on the fence right about now. The price for the 3XL 64GB is $449 if you have Fi. That is a ridiculous price but alas, they're out of stock across the board so I'm back to hoping this doesn't start flashing. 30 day return window is amazing. I think you'll know by then.
[Google Pixel 3 Questions & Answers] decker39:
I'll keep you updated ?
[Google Pixel 3 Questions & Answers] bobby janow:
Thanks. You talked me out of the xl lol. I got a return window of 4 weeks due to the problems I've been having. If it starts on day 29 I'm going to freak..
[Google Pixel 3 Questions & Answers] crispi7:
The screen flash issue was fixed in latest monthly security update (android P) so the change will probably be merged right now in android Q.
[Google Pixel 3 Questions & Answers] decker39:
Ahhh, sorry man, didn't mean to disuade you from the XL, it's just too big for my liking. Keep me posted ?

---------- Post added at 08:20 AM ---------- Previous post was at 08:18 AM ----------

Yeah i read that the latest security update should have fixed the flashing problem, but still plenty of users reporting issues after the patch.
[Google Pixel 3 Questions & Answers] bobby janow:
The screen flash issue was not fixed in the April update as noted above. Perhaps for some with minor display disturbances it was but for a large part of those with hardware defective devices it was not.
[Google Pixel 3 Questions & Answers] bobby janow:
Nah it's ok. You just talked me off the ledge because seeing an XL for $449 was tempting. Then my wife asked, are you going to be happy with that large device? That was it. I removed it from my cart and they sold out shortly afterwards. Day 5 and no flashing yet.
[Google Pixel 3 Questions & Answers] decker39:
Well guys, my Pixel 3 arrived this morning, and 5 updates later aswell as phone restarts, i was able to actually spend a bit of time navigating different features and finish setting it up. I decided to set it up from new instead of data transferring from my Sony. All good so far. Anybody got any advice on Pixel Pulse, apparently this replicates led notifications ?
[Google Pixel 3 Questions & Answers] wangdaning:
Yeah, the XL is quite large. I like the size of blueline, fits in the hand comfortably. It is strange how this screen flash issue is going. Given the number of people reporting it vs the number of devices out there is seems like it might have been a bad batch of devices somewhere. I wonder what else could be causing it other than some devices with faulty hardware. Wonder if it would help if people with the issue started posting their serial number.

[Google Pixel 3 Questions & Answers] bobby janow:
This seems to be the later batch. My wife has and I had a Verizon original bought in November. I never had a flash and neither does she. I traded mine in because I couldn't use the esim on vzw. The Google new ones flashed. Let's see with the one I have now. I think it might flash but I'm trying to think positive. What would the serial number show?
[Google Pixel 3 Questions & Answers] wangdaning:
If we got a pool of the serials with issues we could assume the meaning of the code and see if they came from a similar batch/factory.
[Google Pixel 3 Questions & Answers] decker39:
I noticed when i first booted mine up the battery was quite low so i checked in battery settings and it said the last charge was 129 days ago. Guess mine is from the first batch then ? [MENTION=4850735]wangdaning[/MENTION], what was the Staffs collaborative program you were involved in ?

I am making this post so it is more broadly seen by people who have a specific hardware issue.

This solution is for issues specifically with the board being fried or more likely broken solder connection. I found this solution while browsing Chinese Custom Rom threads and apparently it works.

Absolutely it's better to pay a professional reball the broken solder connection.

There is a do it yourself/cheap method that definitely does not involve using an Oven.

Good Luck

Make sure you followed all of the unbricking steps here https://xdaforums.com/le-pro3/how-to/unbrick-leeco-phones-leeco-variants-t3847220 before even considering this method..

There are 3 unbricking methods mentioned

Qfil with Flash 2.0 or 1.9 ( Try both)

Hi

What do you think, can I repair this problem? :

My phone is dead. It is not able to turn on, it just squezing sometimes, if I push the turn on button. The screen is full black since the shut down. No logo no any fastboot screen, nothing. The led light was pale green before the qfil.
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
I wouldn't bother trying this possible solution unless you are 100% sure that you have broken solder connections. Just because your phone doesnt turn on doesn't mean its the chips. It much more likely that your issue is just the battery.

Also just so you know when the board is fried the phone will still turn on, and will boot to fastboot but not recovery, qfil works but does nothing and if you boot to fastboot and leave it on the fastboot screen the screen will turn to static. At least this is what happens with the majority of chip death issues. However there was one case that I know of on a friends X722 which could not go to fastboot, and that issue ended up being a fried GPU, which this possible fix may resolve.

If you are only getting a black screen leave the phone plugged in overnight ( preferably with a different cable) , After knowing that the phone was charged for long enough what happened? Did the phone get warm at all? Does the phone vibrate?

If the phone does vibrate, try using the QPST method, it's the 2nd post on the Unbricking thread mentioned above in the OP.

Another possible cause of your issue is static, they only way to test and possibly resolved is to unplug the battery from the board and plug back in again. Should you attempt trying this, only use a heat gun to melt the glue holding the screen on...there is alot and a hair dryer will not work, without damaging your LCD.

If I had your issue, I would order a battery and LCD, and swap the battery, there is a good chance it will work. If not you can move on to more drastic solutions such as the one mentioned in the OP. Worse case scenario, you will be out the cost of the battery which is about $7 and LCD which is about $15

This thing here I believe is very important, so much to put it in special color

>>Also just so you know when the board is fried the phone will still turn on, and will boot to fastboot but not recovery, qfil works but does nothing and if you boot to fastboot and leave it on the fastboot screen the screen will turn to static.

I guess it's certain now that I have some harware issue, most probably if GPU is separated from the CPU.

I don't know if it's just me who is unlucky but I have lost yet another USB board. This time the one you sent me burnt up as I connected it to my PC. I don't think it's a cable issue because I was using a high quality USB cable from BASEUS. How could it be that I'm not seeing more complaints like mine?

This time I think it could have been caused by dirt in the port because I'd just returned from my rural area and there I did a lot of work involving dirt. Also, there was a slight shower that got me on my way back and I keep the phone in the pocket with the USB port exposed and looking up. My patience with this phone has just about run out now. This is the worst investment I've ever made on a phone :crying:
[LeEco Le Pro3 Guides, News, & Discussion] tsongming:
Wow, sorry to hear that. I think that those LeEco phones are hit or miss. But it really doesn't seem that they were made to last more that a couple of years. I have fried the usb card myself, when I bought very first leeco, its too easy to fry those cards, and in retrospect the Leeco charge is too powerful. The remaining Leeco that I have left charges much better ( stays cooler) when using my Xiaomi Charger.

I agree that you have had some really bad luck. I would not put any more money into it. you are better off buying a cheap Xiaomi...even a used one. You can find some good deals on Amazon and Swappa. Amazon also has refurbished Samsung phones, and they are highly reliable.

You can get a Galaxy 7 for $139 https://www.amazon.com/Samsung-Gala...s=wireless&ie=UTF8&qid=1573693012&sr=1-4&th=1 and they are really good phones.

Here is a renewed One Plus 6T for $267 https://www.amazon.com/OnePlus-A601...ked+cell+phones+renewed&qid=1573693220&sr=8-4

LG V30 for $177 https://www.amazon.com/LG-Camera-Si...ed+cell+phones+renewed&qid=1573693365&sr=8-21

I bought my daughter an A3 and honestly I can't recommend it enough. For a tight budget I personally feel that this is one of the best deals out there for ony $158 ( $50 less than what I paid 2 months ago) https://www.amazon.com/Xiaomi-A3-64...=sr_1_3?keywords=Xiaomi&qid=1573693435&sr=8-3

It has an Amoled Screen and comes with Android One with zero bloatware. You basically get a custom rom experience with a stock phone. To make matters better Android 10 will be released for the A3 in January. The camera, is light years better than the Le Pro 3 and the processor is honestly fast enough, for most of us. No doubt, its more expensive than just getting another card. But saving yourself from the hassles of these constant issues will make it worthwhile. The only drawback is the screen is 720 instead of 1080. But I swear, if you place in side by side with my Mi8, most people would never guess, that the resolution is a little less. Because it's still an amoled screen.

Best wishes, unfortunately I don't have any more working cards or I would send it to you.

I've learned that quick charge is dangerous. I'm using now an usb meter that doesn't let an output beyond 1.4amps to charge my phone now, it charges pretty quickly in fact and my phone doesn't get hot now (even that I live in a hot area)
[LeEco Le Pro3 Guides, News, & Discussion] twistyplain:
Yeah. The current pushed by the stock leeco charger is either too high (doubtful) or the charging system of the pro 3 isn't designed to handle quick charge 3 very well (most likely). I have used my stock leeco charger to charge my brother's Nokia 8 (Q.C. 3) and it gets just a little warm even with a case on. Also, the leeco charger is Quick Charge 3 certified so they must have made it according to Qualcomm standards.

I think it's the quality of the parts on the phone itself that are substandard. Since this USB board was sent to me by [MENTION=7672955]tsongming[/MENTION] and he had used it quite a while, I believe it could have been perfectly fine. My suspicion is that something else could be wrong with my phone like the USB flex cable. The kind of burning I saw must have been caused by power from the battery because the USB 2.0 port I was connecting to on my PC can only provide 2.5 amps maximum. This is not enough in my opinion to completely melt the usb-c receptacle on the phone. (It's very badly burnt). I will just have to charge the battery externally until I figure out whether it's worth investing any more money into this phone.
[LeEco Le Pro3 Guides, News, & Discussion] tylerciggy:
My X722 died because I just plugged in the cable to charge. Although I have to admit that the phone socket was not in optimal conditions because I used a crappy cable, so the last one I was using was charging fine but it had to enter in an specific position in order to quick charge to function. It's probably the charger IC that is damaged, but I haven't had the money to send it to repair.

As far as I know, the motherboards just provide 0.5amp unless you are using an special port that can provide more power.

In my opinion 2.5amp at 5v is not that good either, because it's pushing the limit of most phones at 5v.
[LeEco Le Pro3 Guides, News, & Discussion] twistyplain:
I am guessing that buying the original $30 USB board from AliExpress won't buy me much time because they have all been used before. Almost every spare part of this phone is not brand new (except for batteries and screens, I guess).

I think it's time to cut my losses. My pro 3 not only needs a new USB board but also a battery and another high quality USB cable. I might buy all of that for $60 only to have the USB port burn again. It doesn't make any sense to keep pouring money into this phone.
[LeEco Le Pro3 Guides, News, & Discussion] tylerciggy:
What ? $30 usd ? I've seen it in $2.5 for 2 boards, well, not original of course.

You just need to check that it has the extra IC, because there are ones that doesn't has it... although I don't remember what was for that IC, but you can easy see it that some boards just are missing a chip.

As for the cable, I'm using some EFFE cables (EFFE is the brand) and they are working wonderfully, I bought 3 for $7 usd, they plug in fine and stay in too, they were recommended to me by a friend and I'm very happy with them. They even stop giving charge to my dead phone because they detect somehow that there is a short, well, at least that is what my usb meter tells me, although I don't know how do they manage to do that, I don't really think they have an IC in them.
