Error 9 often appears when processing firmware update or system restores by iTunes. Several reasons are attributed towards the problem, and we have alredy posted a solution for iPhone error 9 fix related to the NAND Flash error before. This time REWA comes with a totally different solution regarding to iPhone 6 error 9 caused by insufficient soldering within CPU BGA. With the help of our newly developed CNC chip grinding machine, chip removing can be safe and quick without damaging the logic board and nearby chips.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Four steps to help you to solve the iPhone 6 error 9 issue.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. D\u00e9montage du t\u00e9l\u00e9phone<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The phone is stuck in Recovery Mode when trying to start up. Connect it with computer and start system restore via iTunes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L'erreur 9 appara\u00eet. D\u00e9montez le t\u00e9l\u00e9phone et sortez la carte m\u00e8re. Retirez une partie de la plaque de blindage avec une pince coupante.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. Diagnostic des dysfonctionnements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Test grounding resistance value of resistor R0317 and R0316 with diode mode-Abnormal value (480 under normal circumstances). R0317 and R0316 are connected with CPU pin AP31-SDA&nbsp;and pin AR31-SCL directly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. R\u00e9paration des dysfonctionnements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Take down the shield plate of CPU with hot air gun. Then put the logic board on the corresponding position of the CNC mold and fix it tightly. Load iPhone 6 corresponding logic board chip grinding program and start grinding.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Une fois termin\u00e9, retirez la carte logique et utilisez un couteau \u00e0 sculpter pour gratter d\u00e9licatement jusqu'\u00e0 ce que le circuit de la sous-couche du CPU apparaisse. Ensuite, nettoyez avec un nettoyeur de PCB.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Apply some UV curable solder mask to the exposed area, apart from the two bonding pads (SDA,SCL). Once it has been done, put the logic board under the UV dryer lamp for 10 minutes and then take out the logic board.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00c9tamez les deux pastilles de liaison avec un fer \u00e0 souder. Ensuite, soudez le fil de cuivre de 0,02 mm respectivement sur les deux pastilles de liaison. Les deux fils soud\u00e9s se connectent respectivement \u00e0 la pastille SDA correspondante de R0317 et \u00e0 la pastille SCL correspondante de R0317.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Test grounding resistance value of R0317,R0316 with diode mode again-Normal value this time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">4. Test des t\u00e9l\u00e9phones<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Assemblez le t\u00e9l\u00e9phone et restaurez-le via iTunes. Ensuite, activez le t\u00e9l\u00e9phone et testez, dysfonctionnement r\u00e9par\u00e9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Une fois le test termin\u00e9, retirez la carte logique. Appliquez ensuite \u00e0 nouveau un masque de soudure durcissable aux UV sur l'endroit soud\u00e9. Placez la carte logique sous la lampe de s\u00e9chage UV pendant 10 minutes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Assemblez le t\u00e9l\u00e9phone et testez \u00e0 nouveau, tout fonctionne normalement.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Outils utilis\u00e9s :<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Machine \u00e0 rectifier les copeaux \u00e0 commande num\u00e9rique<\/li>\n\n\n\n<li>Tournevis<\/li>\n\n\n\n<li>Pince \u00e0 \u00e9piler (ESD-10 \/ ESD-15)<\/li>\n\n\n\n<li>Pince d'ouverture LCD (M)<\/li>\n\n\n\n<li>Pince \u00e0 d\u00e9couper<\/li>\n\n\n\n<li>Plate-forme de maintenance<\/li>\n\n\n\n<li>Microscope \u00e9lectronique<\/li>\n\n\n\n<li>Multim\u00e8tre num\u00e9rique<\/li>\n\n\n\n<li>Fer \u00e0 souder<\/li>\n\n\n\n<li>Pistolet \u00e0 air chaud<\/li>\n\n\n\n<li>Couteau \u00e0 sculpter<\/li>\n\n\n\n<li>Fil \u00e0 souder<\/li>\n\n\n\n<li>Lampe de s\u00e9chage UV<\/li>\n\n\n\n<li>Bracelet antistatique<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Have you ever come across with iPhone 6 error 9 issue?
