Jiayu G4 (God I hate to title it like this, but yes) stuck in bootloop - Android Q&A, Help & Troubleshooting

How the problem occurred
So a year or two ago I bought a Jiayu G4A/T/Whatever they're calling it and safely got it here. I've used the stock ROM for a bit but I wanted to get rid of the bloatware that was still on it, so I eventually ended up with a properly rooted phone with a ROM from Jiayu.es (Everything worked, have ClockworkMod as recovery, accessible via Mobileuncle Tools), which was essentially a stock Kitkat rom made to work for the phone. Now I got sick of the ROM and recently saw the new EMUI version on Huawei's P8 Lite, so I figured I'd look around for a tailored ROM running that, and ended up at "jiayu-emui-3-0-stable" from Needrom.
What I did
1. I downloaded a ROM from Needrom with identifier "jiayu-emui-3-0-stable" (I can't post external links)
2. Backed up my important files following a guide from androidcentral titled "[Guide] How to Backup and Restore Apps and Data when installing new ROMs" that I can't link,and did a full backup using CWM
3. Placed the ZIP on my internal SD card, went into recovery, wiped data/cache (not dalvik, since it wasn't described in the instructions, I think this might be a probable cause) and installed the new ROM from ZIP
4. Rebooted the phone and now it's stuck in the boot loop I mentioned.
What the problem is
Bootloops aren't that much of a problem usually, except this one is... I can't get into recovery mode. From there on it'd be cake, since I made the right preparations, but I can't get into it. While connected to my PC it keeps powering on, showing a splash screen from Jiayu.es briefly (which shouldn't be present anymore) and powering off after 10 seconds, only to come back to the splash screen.
What I've tried
I've unplugged it, removed the battery, waited to get a full power cycle and tried to hold my buttons in these combinations: [power button + volume up], [power button + volume down] - but neither work. It just keeps going with the boot loop. I can succesfully power it down, and when I plug it in from there it shows the low battery image. At the moment of seeing that I thought I could connect to it using ADB / Fastboot, but no luck there either. It keeps saying no devices found, and with fastboot it keeps on <waiting for device>.
My questions
What exactly can I do if there is no way for me to get into recovery mode? Are there any alternatives? How can I get my device to be recognized by ADB? Is that even possible? Why is this bootloop any different from others?

Update from the massive Q&A thread:
ZipAddict said:
Is it booting up on its own too after being off? This happened to wifes phone and it turned out the power button was stuck. I took a pencil and hit the power button with the eraser a few times and it worked then. Her case mustve dislogded it. I will keep my fingers crossed for u. If not send me a private message and i will look for an answer tomorrow and get back with u

Thank you for the reply!
Yes, it does. I took the battery out and let it lay disassembled for a night, after which I cleaned it a little and re-inserted the battery. With the case back on, nothing happened, so the power button wasn't stuck for sure. When I powered it back on with the power button (no USB attached) it showed the emblem for ~8 seconds and powered off. It then buzzes to show it's powered on again and up comes the splash screen again. Could it be that the ROM was just a rebooting falsehood? Why would it disallow me getting into recovery mode? I really hope there is something that can still force the device into recovery mode / interact with it somehow while in this state.
Oh, I also tried to see if the volume down button was broken but all the contacts seem intact, plus, they worked an hour before I started switching roms.

[Q] Bricked my phone... another one bites the dust

YUP. I "soft bricked" my t-mobile galaxy s (vibrant here in the us) or so I hope. The phone was rooted via z4 on the latest android t959uvji6 from t-mobile.
How did i do it? Brick my phone that is...
The 3d gallery was pissing me off by picking up everything on the phone. I tried clearing the default setting via the manage app but nothing changed so I decided to delete it. First backing up the apk and odex file from the system folder with titanium backup then deleted them from the system folder via root explorer. Rebooted the phone, pulled out the battery, waited for 30 seconds or so, popped in the battery and booted up the phone w/o any issues.
I tried installing the backup 3d gallery apk file and got the "app not installed" error on numerous attempts. Then tried simply copying it over again with ti backup and nothing happens. Gave up and said the heck with and went the factory restore route, got all the relevant apps installed and tried reinstalling the 3d gallery apk but resulting in the same "app not installed" error prompt. So I again copied over the apk and odex file into the system folder. Rebooted and nothing... phone does not boot into the home screen.
At this point here is what the phone is able to do.
It will boot up and display the default galaxy s animation, goes through it's array of colors then comes to a stop at all white letters then the screen goes blank and nothing happens - zip. nadda. i left it on for 12hrs like that - blank screen w/all the hard keys lit up.
What i did notice was win7x64 recognizes the phone after it gets into the blank screen of death as mass storage units.
So far i've tried booting into the recovery screen via the three button method and none of them works.
Did the karma-volume up-home-power twist - nothing
Did the karma-volume down-home-power roll - nothing
Did the karma-volume up and down-power jiggy - nothing
I tried the key combos for about 2hrs without any success then jumped into adb. After reading for a bit I realized that the phone was still rooted and the debug mode was enabled the last time i shutdown the phone (good'ol ti-backup)
For a while there adb did not recognize the phone at all but with an odd power cycling while spamming "adb reboot recovery" it was able to finally nab hold of the phone and jump into the recovery console. At first I thought it was pure luck so unplugged everything and tried it again - works every time if i did the odd out of sequence power cycle while spamming the adb console with "adb reboot recovery".
In the reboot recovery - deleted the user data and did the restore.
Here's where I think I really screwed up - now the phone is no longer in debug mode.
Long story short - is there a way to get into the recovery screen w/o debug mode on?
**quickly pulls on flack jacket**
but seriously any suggestions would be great
Wrong section bro. You probably won't get an answer here.
To answer your question. Yes, Remove Battery, Plug your phone to USB, Press and hold the volume down and the power button Put the batter back on. This should get you into download mode. Use ODIN to restore.
the usb jig trick did the work - now i have two phones!!!! (bought the nexus s yesterday) lol
Time to ODIN.
To access Download mode.
Unplug. press volume up and down togheter, and connect USB. VOILA!
If ODIN does not recognize it, plug and unplug again

no!
Why the hell are people giving others ideas on how to get into download when their doing it wrong.
its JUST THE VOLUME BUTTONS, NOT THE POWER BUTTON ALONG WITH IT.
volume + power = Recovery, which in this case you probably cant get into
Volume - Power = Download mode, which everyone can get into unless if they somehow hard bricked, if its possible.

Phone won't turn on

Sometimes my I5500 won't turn on.
This has already happened 2 times (with two different firmwares I5500XWJPL and I5503TTLPJP9). The phone shows absolutely no signs of life - screen is black, no sounds, nothing.
I tried everything: pressing VolumeDown+Center+Power, VolumeDown+Home+Power, with or without battery/SIM/charger/SD. Tried removing battery for 30 minutes, charging battery in external charger.
Sometimes when charger is connected, it shows green battery on the screen, but still won't boot.
Last times I spent several hours fiddling with it until it finally turned on..
Can someone tell my if there is a fast way to revive the phone next time this happens?
Maybe your arm11boot is damaged, but still partly working. You need replace that partition. I saw arm11boot partition image in one Russian FW. I can't remember actual name. You can try that, but caution. You might brick your phone compleatly!
sorry for reviving this thread.
but I got the same problem now. Tried to use ROM Manager to install CWM Recovery (following a blogpost explaining how to install a Custom ROM on the SG5). Might have accidentally clicked a different CWM Rec. version than I thought I did. However, ROM manager showed a message, telling me that CWMR was installed correctly.
So I wanted to boot into CWMR up to flash my device with the latest CyanogenMod 7 port from MADTeam. Used the "boot into recovery" option from ROM manager for that purpose. The next thing I know is my phone not reacting to anything.
Tried all methods mentioned afore (Vol- + Home + Power / Vol- + Center + Power, with/w.o. SD card and/or battery inserted). Screen keeps being off, no sign of life, phone wont even do anything when plugged to my PC or a charger.
The phone has been rooted properly before and was running Stock 2.1. Houston, we've got a problem.

Take your battery out, put it back in and turn your phone on, then it will boot up into recovery mode. I also have this problem from time to time, sometimes it boots into recovery, sometimes not and i have to remove/replace the battery.
I actually thought that this might be a useful feature for say - if you wanted to upgrade a friends phone to cyanogenmod in the pub, for example.
did try that. now even had the battery removed for about an hour. put it back in. still no reaction on pressing the power button or one of the combinations that should put it into recovery or download mode. no sign of life when plugging the phone to my computer or the charger.
I do fear the worst, though I dont know how ROM manager was actually able to brick the phone that badly.

In that case then this also happened to me - While exploring the rom manager application after first ever flashing my phone i accidentally selected the wrong phone model from the 'flash clockworkmod recovery' option and my phone was gone forever. Perhaps your problem is similar.
(Luckily it was under warranty and they replaced it. The method worked so well in fact it happened 'accidentally' a second time i acquired a 3rd i5500 out of the box )
bought mine already used, so no chance for a warranty replacement :/
gonna give it a shot with a usb jig now, maybe i can get the thing into d/l mode with that, so I can revive it with odin.

what about the Emergency DLoad Mode, which is not the Download Mode? Did you try it?
{ brvsn ~ CM7 on GT-I5500 ~ Tapatalk }
how do I access emergency d/l mode?
UPDATE
I actually CAN get download mode (or what I assume it to be) running by pressing Vol- + Menu + Power (while Vol- + Home + Power wont do anything, nor does the USB jig that arrived today). Took me some time to discover this, as this doesnt seem to be the usual 3-button-combination used. BUT: while the phone is now recognized by my PC, it wont show anything on the screen.
Odin (tried 4.28 and 4.43 on both win7 x64 and x32 and everyting related to Kies shut down) does now detect my phone. However, it always gets stuck at "Setup Connection" when I try to flash the stock rom or CWMR. Tried different approaches (from starting DL-mode with the phone being connected to my PC to separately starting DL mode and then connecting, starting it up with the battery already being in place, starting it up with sliding the battery in place while holding the 3 buttons etc.), none of them gets me further so far.
Another hint I found was setting the Baud-rate of the Samsung mobile modem to 203400, but this, unfortunately, didnt change anything.
Anyone got a lead on how to get Odin finally started properly?

ops, sorry: I miss your previous message!!
Now I got it and read this last post.. let some time to think about it, I'll replay soon.. but, generally speaking, at this point there's not so much you can do..
If you can get it into Download or Recovery mode, then you should be fine.

download mode is Vol - / Central Button / Power..
Im aware of that. However, Vol- + Menu + Power is the only key combination that the phone will react upon.
Anyway. Brought it to a mobile phone shop on friday, called them on monday and according to them, the phone should be fixed by tomorrow, wednesday. Seems like ROM manager has done damage that cant be undone without knowing how to handle a JTAG device. But at least its not completely broken. Learning that will cost me 25 Euros, though.
One final update to this: Got the phone back today, they were indeed able to fix it.
Conclusion:
While installing a non-fitting CWM-Recovery through ROM Manager will make your Galaxy 5 unfixable via Odin, it still can be saved by making proper use of a JTAG.

[Q] Stuck in CWM - Power button fail

Alright guys. I hardly post on here because I know many questions have been answered. I searched and was unlucky.
I had my phone rooted last year, but went completely back to stock because I was tired of the battery drain. Recently, maybe a month or 2 ago? I updated to 4.0.4. That's when my power button stopped working. All of a sudden, about a week after, it started working again. So I was happy. A week ago, it stopped again. Using my phone everyday, it got really frustrating. I was dumb and didn't search for a fix, which I later found a temporary fix.
So I decided to root again. Well, when I plug my phone into my laptop, it tells me "USB device not recognized" so I looked for a way to root using mobile. Found a few videos on YouTube with links with an .apk and did it that way. I had CWM backed up in Titanium Backup, so I restored it and opened it. I wanted to flash a ROM on my phone, but I didn't think before I went into CWM. Stupid, I know lol.
Now I'm stuck in CWM, without a working power button. I tried taking the battery out, and putting it back in. It still boots into CWM. I tried taking the battery out, plugging in my phone, and putting the battery back in, and still CWM. I've also tried taking the battery out and leaving it out for a while then putting it back in. And also, taking the battery out and leaving it out for a while, plugging in my phone, then putting the battery back in. Still in CWM. I've also tried hitting the Home button (does nothing). Nothing happens when I hit the Search or Back buttons either. I hit the Menu button, and it hides the menu, then I hit it again and the menu comes back.
Luckily, I'm due for an upgrade next month so recently I've been using my super old "Krzr" flip phone. I miss having a Smartphone though!
Any help would be appreciated!! Please don't flame me lol

Why don't you try repairing the power key. I strongly believe It may be a hardware problem
Sent from my SGH-I777 using xda premium
If you have USB debugging enabled you could connect through ADB and force a standard restart.
If that's not an option and you can't get out of recovery (Had a very similar issue with my wife's phone when her power button went) you can use an odin 1 click downloader to revert it to stock and it will then restart normally. I then used the odin 1 click downloader to install a rooted stock rom. After that I took a touch enabled kernel (like Siyah) and installed that through Android Terminal emulator. Now you can boot into CWM and be able to use the touch screen to navigate. It's a pain and it requires a full wife and reversion to stock but it does work. Then you flash a rom that allows for holding the volume down to wake the screen or a kernel like AJK that allows for swiping across the screen to wake the phone.
I'm sure your power button failed so as the previous poster suggested you can look into getting it repaired. I don't have the link on me but there was a place listed here on the forums before that were like $40 to do the hardware replacement.

Thanks for the info. Late last night I pressed the power button while "reboot" was highlighted in CWM and it finally worked. But it only worked that once, at least it got me out of CWM. My phone reboots a LOT. At one point, it rebooted at least 3 times in a row; getting to the AT&T screen and rebooting then.
I've decided to just deal with it lol I'm probably going to see if AT&T can kindly let me upgrade this week instead of waiting until June 1st.
Again, I appreciate the info!!
Do a clean flash
Ok since you are saying your phone's power button started being flaky after a ROM flash, I'm thinking most likely it is not a hardware issue.
Bad flashes, loading different bootloaders, or kernel flashes and then panics happen for various reasons.
You need a clean flash, reset to factory (erase data/cache multiple times) and reboot.
Back up first (like right now), then gather your operation tools.
1-Download I777 usb drivers from Samsung itself, uninstall the current ones, and install the new drivers (Do this plz)
2-Download the stock ROM from [INDEX]AT&T I777 GSll {Root/ROM's/Tools} thread by t3chn0s1s in AT&T Samsung Galaxy S II Android Development (http://forum.xda-developers.com/showthread.php?t=1301682)
3-from that thread get: A) Odin B) UCLE5 ROM
4-Run Odin and try connecting your phone to see if it stays in the Download mode successfully (phone off, Odin loaded on your PC, plug in your phone to your PC while holding down both volume keys, release the keys once your COM connection port lights up) sometime holding down the volume down only button works instead of both depending on what you flashed before.
5-load up the stock .tar UCLE5 file in the PDA section, leave all the Odin default check marks on and add the flash bootloaders check mark too(DO NOT check the repartition option)
6- once a clean flash finally happened (doesn't matter if the phones boots up all the way or not yet) pull the battery, and get to recovery and reset / factory reset and let the newly flashed ROM boot up
7-let it settle for 10-15 minutes and then reboot it.
Good luck,
I727-CM10.1

CWM Recovery hanged while erasing... bootloop problem.

Hello, today I wanted to restore my previous CWM backup. So i started with cleaning partitions before restoring. I've begun with system and my phone hang. I waited about 30 minutes, then pulled out battery with hope I'll try again via CWM. The thing is - I can't boot it into recovery: Volume Up/Volume Down+Power leads to normal start up (LG screen and nothing further). So i connected it to PC and wanted to make it right via ADB. Unfortunely it seems I had USB Debugging turned off, and ADB isn't recognizing my phone now... What should I do now?
I have rooted D620r with unlocked bootloader.

You must never delete partitions before restoring a backup especially system!!
CWM will do that for you...
Boot your device in factory reset mode (which simply boots CWM) by doing the following key combination: (while your device is off - pull and plug the battery to be sure) press and hold Vol - and power, when you see the LG logo, release the power button and press it again. Hold them until you see the facory reset mode, then simply enter YES. It will reboot to CWM.

Weird, I was always doing this when I had HTC Desire S
Used this countless times and always worked!
Ok, i've done as You said, something like CWM loading screen appeared, and then went back to LG Screen. LG Screen standing still and nothing happens
The only good thing is that I can access ADB for 20 seconds when CWM is "loading", but no action can be executed - every command ends up with "waiting for device".
Thanks for Your reply, though! :highfive:
EDIT:
I solved my problem by using "Emergency software restore" mode featured in "LG User Support Tool". I got clean, unrooted system now and I need to modify it again but...
...THAT'S WHY I REGISTERED HERE!
Lock bootloader
Hello everyone.
I was just going to try out CM11, but got one question. Is it possible to lock the bootloader and revert everything to stock? There were some talks about new stock ROMs coming out and they might not work after a custom ROM.

[Q] Bricked phone - Boot loop - Recovery & Download mode not working [HELP]

Hello guys,
I've got a big problem with my I9300 and therefore I would like to ask here for any help. (If I'm in the wrong section, please move the thread to a correct one)
I had installed the Resurrection Remix ROM, v5.2.6. from 30.12.2014 and Googy-Max 2 recovery (CWM based) on my phone. I was using it for days and all worked fine.
One day I turned the phone off and I wanted to restart it. But it never restarted again; it ends up in a boot loop. It shows me the white Samsung Boot-Logo for some seconds, then a total black screen and the same thing repeats in a loop.
So I wanted to get into the recovery for wiping etc. but I couldn’t access the recovery. Nothing happens by pressing the relevant buttons. The device is still hanging in the boot loop. So I wanted to flash via Odin, but this isn't possible. I also can't go into the download mode. After pressing the relevant buttons, the green warning screen appears, which asks me if I really want to go to the download mode. But when I press volume up for "continue" or even if I don't press anything, the phone turns off and the boot loop with the white Samsung Logo starts again.
Therefore I ordered a USB JIG for forcing the device to go into download mode. When I plug the USB JIG in, the device actually goes into download mode but this status holds on only for a few seconds. After accessing download mode through the JIG, after a few seconds the phone turns off, restarts, (and because the JIG is still plugged in) the download mode appears again and it ends in a loop.
At first I thought maybe the power button is sticking and therefore the device turns on and off autonomous. But definitively I can negate it, because I opened the phone and removed the power button and nothing changed. Also by pressing the power button on the mainboard I can clearly hear the "click".
So I started a new attempt. Although the time, in which the device stays in download mode before turning off, is very short (only a few seconds), I tried flashing an other recovery, namely TWRP v2.8.3.0. So I prepared ODIN, plugged the JIG into the device, by appearing the download mode I switched cables and an other person clicked start at ODIN and it worked. So now TWRP is installed. Now I also can't get into recovery but after flashing TWRP there exist two little differences. First, after pressing the relevant buttons, TWRP appears for less than 1 second until the phone turns off. Secondly, when I plug the device in for charging, the Samsung charging logo appears for some seconds, then for less than 1 second appears a charging logo from Lollipop and the device ends up in a loop by displaying alternately the two different charging logos. Before flashing TWRP, the device booted in a boot loop (as I wrote above) by plugging it in for charging.
So the main question: how can I get my device work again
I tried telling you all details so that you have a better view of the problem.
Maybe I should flash a fully (stock) rom, but as I told you the download mode appears only for a few seconds. Flashing a recovery was possible, because the recovery file is very small - 7 MB. A full rom is much bigger and I think by flashing a complete rom, the device would turn off while Odin is flashing, therefore I ask first here for any assistance.
Thank you very much in advance!

But definitively I can negate it, because I opened the phone and removed the power button and nothing changed. Also by pressing the power button on the mainboard I can clearly hear the "click".
So I started a new attempt. Although the time, in which the device stays in download mode before turning off, is very short (only a few seconds), I tried flashing an other recovery, namely TWRP v2.8.3.0. So I prepared ODIN, plugged the JIG into the device, by appearing the download mode I switched cables and an other person clicked start at ODIN and it worked. So now TWRP is installed. Now I also can't get into recovery but after flashing TWRP there exist two little differences. First, after pressing the relevant buttons, TWRP appears for less than 1 second until the phone turns off. Secondly, when I plug the device in for charging, the Samsung charging logo appears for some seconds, then for less than 1 second appears a charging logo from Lollipop and the device ends up in a loop by displaying alternately the two different charging logos. Before flashing TWRP, the device booted in a boot loop (as I wrote above) by plugging it in for charging.
So the main question: how can I get my device work again
I tried telling you all details so that you have a better view of the problem.
Maybe I should flash a fully (stock) rom, but as I told you the download mode appears only for a few seconds. Flashing a recovery was possible, because the recovery file is very small - 7 MB. A full rom is much bigger and I think by flashing a complete rom, the device would turn off while Odin is flashing, therefore I ask first here for any assistance.
Thank you very much in advance!

Check and make sure that your volume buttons and home button are not stuck also. If they are not, I would suggest a visit to a repair shop as your EMMC chip might be weak already.

Hello guys,
I've got a big problem with my I9300 and therefore I would like to ask here for any help. (If I'm in the wrong section, please move the thread to a correct one)
I had installed the Resurrection Remix ROM, v5.2.6. from 30.12.2014 and Googy-Max 2 recovery (CWM based) on my phone. I was using it for days and all worked fine.
One day I turned the phone off and I wanted to restart it. But it never restarted again; it ends up in a boot loop. It shows me the white Samsung Boot-Logo for some seconds, then a total black screen and the same thing repeats in a loop.
So I wanted to get into the recovery for wiping etc. but I couldn’t access the recovery. Nothing happens by pressing the relevant buttons. The device is still hanging in the boot loop. So I wanted to flash via Odin, but this isn't possible. I also can't go into the download mode. After pressing the relevant buttons, the green warning screen appears, which asks me if I really want to go to the download mode. But when I press volume up for "continue" or even if I don't press anything, the phone turns off and the boot loop with the white Samsung Logo starts again.
Therefore I ordered a USB JIG for forcing the device to go into download mode. When I plug the USB JIG in, the device actually goes into download mode but this status holds on only for a few seconds. After accessing download mode through the JIG, after a few seconds the phone turns off, restarts, (and because the JIG is still plugged in) the download mode appears again and it ends in a loop.

Your power button is failing, stuck in 'pressed' position. Try pressing repeatedly power button for several seconds, then release it completely. It shall bring it back to life. Visit your local service, or prepare tin, heat gun and soldering pistol. One button cost $0.2, they are selling them on eBay in sets of three (and 10, and 100....).
Happened to me some time ago, and video on youtube helped me to dismantle my phone, pull broken button out of it, and change it for new.
My phone was cycling like yours.

As said your emmc chip maybe failing.
The dead boot thread maybe of interest to you.

He said he has tested this and can also hear the micro-switch clicking.

Thank you very much for helping! :good:
So the question is, whether it's the power button's or emmc's fault...
I did a little searching and found this video. I've got exactly the same problem like the guy. At 1:06 following the boot loop, at 1:34 following the problem with downlod mode.
Although he thinks it's caused to the sudden death problem, but at least in my case I think it's wrong because months ago I did the eMMC Brickbug Check.
Also I noticed a probably important detail. When I put the battery in the phone, it automatically turns on without pressing the power button like in 1:04-1:09 in the video. Which normal working phone turns itself on by simply putting in the battery...?
So it must get a command for turning on - (possibly through a defect power button?)
@Virnik0, do you remember, if you could hear the micro-switch clicking on your phone before replacing the button on the mainboard?

Your power button is faulty, replace it before you try fixing anything else.
Thank you very, very much for helping! :good: :good: :good:
Truly the power button was fault although you could hear clearly the "click".
I unsoldered and removed the power module and (by startig with JIG and rebooting via ADB) the phone works as it should. :victory:
Now I'm trying to solder a new power button......it's a bit tricky
Again, thank you very much guys!
I had the same problem, pressed the button many times, and it helped. Thank you for your suggestions
